The Columbia Museum of Art
implemented a renewable energy project using a recently installed solar panel array on the roof of its building which is reducing the amount of energy the museum has to purchase. The Museum received a $213,500 grant from the US Department of Energy to fund the 177 solar panels, special installation equipment, 6 electrical inverters and a web based monitoring system. A special educational webpage at columbiamuseum.org provides visitors with fun facts, live readings of energy saved, photos and interactive games for kids.
For more information on renewable energy please visit NCInsurance
The Solar Panels will:
PRODUCE 10-20% of the Museums daily usage
OFFSET 40 tons of carbon every year
SAVE 379 trees per year
GENERATE 53,340 kilowatts per hour
This project is a great example of using renewable energy to improve the environment and the economy. Patrons of the museum will be able to learn more about solar technology as they see it work first hand, SC Energy Office
director John Clark said.
This scalable project fosters market penetration of renewable energy technology by promoting the benefits of solar power production. As a downtown anchor, the Museum endorses a cleaner, healthier environment by utilizing a renewable resource to reduce and displace its traditional electricity consumption. This is the only solar project of this size in the city of Columbia.
We are thrilled to be making technological advances that are greatly impacting our environment in a positive way. Additionally, this project allows us to reduce our utility costs and to redirect those resources toward programs that advance our educational mission, Museum executive director, Karen Brosius, said.
The South Carolina Energy Office (SCEO) provides a broad range of resources designed to help citizens, businesses and public entities save energy and money. In recent years, the SCEO has helped save South Carolina over $250 million through public and private energy-saving measures and new energy technologies. The SCEO is a unit of the South Carolina Budget and Control Board. Additional information can be found at _URL_.

Objectives: Health care services in Malaysia are widely available and accessible at a minimal cost. However, in pursuing with the health care reform, policy-makers and hospital managers need to know the unit cost for the purpose of planning and efficiency of providing the services. This study estimated the cost of out-patient services in a public hospital
Methods:The study was conducted in a 341 bedded hospital that provide secondary level care to 24,486 in-patients and 127,389 specialist out-patients in 2010. The costs were estimated using a step-down approach where the costs were allocated to the different cost-centres. Capital costs were annualised cost of capital item with life expectancy of more than 1 year and recurrent cost were all inputs consumed within a year. Total costs were then allocated to the in-patient and out-patient services based on historical financial data with a ratio of 1: 4. This was then followed by a stepwise approach of allocating the ancillary department cost centres to the clinical department cost centres. The unit cost per patient visit was calculated based on the number of visits for each department. Base year of 2010 was used to calculate the cost and patients visits. Costs were calculated from the perspective of the hospital.
Conclusions: The findings provide an estimate of the costs for out-patient visit. At the current minimal fee of MYR 5.00 (USD 1.5), the Ministry of Health is subsidising more than 95.0% of the health care cost for each patient. These estimates provide the policy-makers with an understanding of the cost data should they need to establish a cost basis for payment rates.

The Brandenburg-Prussian Superior Board of Mines in Berlin Responsibilities, Tasks and Leading Personalities from 1810 to 1838
The fact that the Brandenburg-Prussian Superior Board of Mines or the Superior Board of Mines for the Provinces of Brandenburg and Prussia only existed for 28 years is probably why this authority has failed to receive the credit it deserved for its work in more recent histories of mining administration. Nevertheless, the establishment of this now virtually forgotten Superior Board of Mines in 1810 can be regarded as a result of the Stein-Hardenberg administrative reforms. To demonstrate this, the article begins with a brief review of the mining laws and the administration of the Prussian mining industry towards the end of the 18th century.
The report then describes in detail what led to the establishment of this provincial authority and how its responsibilities changed over the years from its foundation in 1810 to its dissolution in 1838. A close look is also taken at the Board's staff, in particular the long-standing head of the Board and subsequent Director of Mines, Hans Otto Philipp Martin. Before he took over the management of die Silesian Superior Board of Mines in 1833, he fought in the mid-1820s for the survival of the Brandenburg-Prussian Board, which was already doubtful only 15 years after its establishment. In the end, however, he was unable to prevent the Superior Board of Mines for Brandenburg and Prussia having to hand over its work to the Berlin Superior Mining Directorate and other subordinate authorities. It was finally dissolved in 1838.


Take the 2-minute tour ×
I was wondering how one can rescue all of the prediction results when using the Java API for liblinear.
As it is well documented one can rescue the accuracy of the prediction with the following code:
Feature[] instance = new FeatureNode[5];
double prediction = Linear.predict(model, instance);
But how can we rescue the rest of the results kept in a file that is given to us when running for example:
./predict -b 1 testfile.test modelfile.model resultfile.out
Hope you can help, for the moment I am rescuing the data from the file but is most inefficient having to go to disk to get it. Thanks in advance.

If I understand you correctly, you're trying to get the probability results in runtime. Well, what i'm using is the following code:
double[] probabilityResults = new double[];
double prediction = Linear.predictProbability(model, instanceToTest, probabilityResults);
in the probabilityResults array, you'll find the probabilities of prediction. Good luck!

Conductive Coating (SEM)
Conductive coating with a few nanometers of carbon or noble metals is often necessary for analysis of insulating specimens in high-vacuum SEMs. Conductive coating is required when charge cannot properly dissipate and the electron beam charges and/or damages the specimen.
Carbon coating is typically recommended for elemental analysis (EDS) as noble metals have higher interference with characteristic X-ray signal from the specimen (exact requirements will vary between different materials). Carbon can also be used for imaging, or in very thin layers to coat insulating specimens requiring electron backscatter diffraction (EBSD).
Noble metal coating is typically used for secondary electron (SE) imaging of specimens, though under the right conditions can be used for other techniques.

Monkey Business – Rounding to Nearest Ten
I've been working on a comprehensive Notebook lesson called Monkey Business that helps students learn and review basic procedures for rounding to the nearest 10 and the nearest 100. In this lesson, I created a fun review activity called Banana Rama where the goal is to collect 10 bananas as fast as possible by touching on the correct answer to a rounding problem.
I thought it would be useful for teachers if I put the Banana Rama activity into a separate Notebook file and place it in the Free Resource section of The Notebook Gallery website. On the last page of the file, I also included instructions for how to create new versions of the activity that use different numbers so teachers can continue to reinforce rounding to 10 without using the same numbers over and over again.
The complete Monkey Business lesson will be available on The Notebook Gallery resource site in the next day or two. The 80+ page lesson introduces the concept of rounding, provides a fun method for remembering the rules for rounding, and reinforces the concept of rounding through examples and assessment activities.

DNR fisheries biologists write Status of Fishery Reports on major lakes and streams around the state. These reports contain the environment, both physical and chemical, the history, including all stockings and fish surveys, Current status of the fishery, management operations, and finally Management direction recommendations. These reports are available online on the DNR's web site. Today we will look at a gem of an inland lake, Gratiot Lake.
Gratiot Lake, which lies at the feet of Mt. Horace Greeley and Mt. Gratiot, contains 1,438 acres (2.25 sq miles) and is the largest lake in Keweenaw County. These peaks are the two highest points in the Keweenaw, at 1550 feet and 1490 feet, respectively. Gratiot Lake is at 743 feet, while Lake Superior is at 602. It has a maximum depth of 78 feet and averages 25-30 in depth. Fifteen percent, or 216 acres, is less than 15 feet deep. It has four inlet streams, Eister Creek, Sucker Creek, 932 Creek, and an unnamed creek. It has an outlet, the Little Gratiot River, which flows about six miles into Lac La Belle. The water is very clear, one being able to see bottom in 20 feet of water. The oxygen levels and pH are good for aquatic life.
Gratiot Lake has a long history of fish stocking, with the first in 1934 and the last in 2004, in 31 different years and 10 different species. The species stocked were large and smallmouth bass, walleye, northern pike, northern muskie, tiger muskie, yellow perch, bluegill, lake trout, and rainbow trout.
Although 110,000 bluegill were stocked, none are present today, as Gratiot Lake lies north of their historical range, with mid-Houghton County being the northern extent of bluegill.
In 1962, a single stocking of 3,000 northern muskie fingerlings was made and will be discussed later. Of the 10 species stocked, five are currently found in Gratiot lake, so not all stockings are successful.
Ten fish surveys have been conducted on Gratiot Lake, with the first being in 1926 and the last in 2011. The 1926 survey found yellow perch and pike abundant, rock bass abundant, but smallmouth bass moderately abundant, and brook trout present, but rare. The brookies probably came out of the creeks entering the lake.
For more information
If you have questions regarding this column, and/or would like to see more of this type of report, please email the Daily Mining Gazette.
The next survey, done in 1938, was more comprehensive and attempted to see if any of the almost 1.5 million walleye fry stocked in the four previous years had survived. None were found. They did report about the same fish and numbers as the 1926 survey.
They did report on minnow species sampled, which are important as forage for game fish. They found blunt nose minnows, Johnny darters, Iowa darters, sculpin, log perch, and ninespine stickleback.
The next seven surveys were done in 1953, 1957, 1968, 1977, 1987, 1997, and 2005. These were made to evaluate the various stockings of walleye, muskie, lake trout, and rainbow trout. No lake trout and very few rainbow trout were found in these surveys. All surveys reported rock bass very abundant and small.
In the early 1980's smelt were reported by anglers and also captured in surveys.
The 1987 survey found the first walleye, the result of the 1985 and 86 fingerling plants. The recently developed smelt population mostly likely contributed to their survival.
The 2005 survey was the first to capture muskie, although there were reports previously anglers had caught them.
The 2011 survey's goal was to evaluate and get a population estimate of the northern pike, muskie, and walleye. It was done with fyke nets and electrofishing, so all the fish could be released back into the lake unharmed. Several members of the Copper Country Walleye Association assisted DNR on the survey and reported it was great fun and a tremendous learning experience.
Ten fish species, excluding minnows, were captured, including walleye, pike, muskie, smallmouth bass, yellow perch, pumpkinseed sunfish, rock bass, bullhead, smelt, and common white suckers. The bullheads were a first-time discovery and probably came from a well-meaning angler dumping his bait bucket after a day's fishing.
Common white suckers were the most numerous, numbering over a thousand. Walleye were second-most common, with 659 captured. They represented 20 different inch classes from 5-25, with 139 being in the 15-inch class. Of the total, 391 or over 59 percent of the walleye were legal size of 15 inches or greater.
The walleye fishery is very good. Seventy-eight pike were handled, with 28 or almost 36 percent being the legal minimum size of 24 inches. Of the 24 smallmouth sampled, 17 were 14 inches or greater and the largest in the 17-inch class.
Seven muskie were captured, ranging from just over 10 inches to a monster female of 51-plus inches. The range of sizes indicates they are naturally reproducing, albeit at a low level. The large female, weighed over 50 pounds, and as far as is known, still swims in Gratiot Lake. So, if you are fishing on Gratiot Lake and something very big grabs your lure and suddenly breaks your line, this may have been the large muskie.
Rock bass continue to be small and very abundant, while perch populations are low.
In 1961, a public access site was purchased and developed. It is located on the north side of the lake, off Gratiot Lake Road.
In 1947, 90 brush shelters were placed along the 15-foot contour and another 600 were placed in 1958. It is not known if any of these remain or are functional.
Management direction is totally up the the Fisheries Division of the DNR. A couple of my thoughts: Protect the smelt population by banning dipping in the tributary creeks. They are a very important part of the forage base and over time, a winter ice fishery could be developed. A low-level stocking of muskie fingerlings, in my opinion, of say 5,000 every third year, would be appropriate. This would potentially create a better fishery, while reducing the white sucker population, the muskie's favorite food.

should be done to prove this.
When using the commission expense from the tax return be ALERT -- the commission expense might include wages and thus you have an employee vs. independent contractor issue (see section on Employee vs. Independent contractor, below). Separate the wage expense from the actual commission expense. The commission expense can then be used in an algebraic formula to determine retail sales.
Method 3 - Retail Income Formula
Information needed:
 1. Commission expense on tax return
 2. Commission percent paid on retail sales
Commission Expense divided by the Employee Commission percent paid on sales equals Retail Income
There are two items to consider when reconstructing retail sales using this formula:
 1. Consideration for special sales on products (there might not be a 100 percent mark-up) and
 2. Consideration for "walkthrough" traffic where no specific worker receives a commission.
It is worth reiterating that these audit techniques are guides and not absolutes. However, they have been effective in previous examinations. Using the techniques, adjustments have been made to the individual (booth renter) who failed to report his or her commission income. In the situations encountered, Forms 1099 were not issued by the salon owner for the commissions paid. In addition, salon income was also adjusted. The salon had understated retail revenue. The first indication of a potential problem was noted through the COGS percentage comparison.
Example - Retail Income Formula
Information provided:
 1. Commission Expense per Tax Return equals $15,000
 2. Commission Percent equals 15%
 3. COGS equals $53,000
 4. Retail income per tax return equals $105,000
COGS times 2 equals the Potential Retail Income
$53,000 times 2 equals $ 106,000
Retail Income equals the Commission Expense divided by Employee Commission Percent paid or $15,000 divided by 15 percent which equals Retail Revenue of $100,000.
Analysis of Reported Retail Income:
1. There is a percent mark-up on cost. The industry practice is 100 percent mark-up on cost. This mark-up percent is reasonable.
2. The commission expense reported on the tax return indicates retail revenue should be at least $100,000.
Note: Small amounts of skimming are not easily identified. These two formulas were designed to identify large discrepancies.
Rental Income
If all stylists are employees there will be no rental income.
If the salon has all booth rentals, the salon owner is a landlord. Verify the available spacehow many chairs, or "booths" are there, and the number that were occupied. As with any landlord, be suspicious whenever there are unrented booths. This means the business is operating below capacity and costing the landlord money. It is very unlikely the business would have unrented booths.
Appointment Book
The appointment book can be used as a tool in an income probe. Have the salon owner or individual (the individual may be a stylist or some type of worker providing a service) go through a day in the appointment book and explain the scheduling and recording procedure for appointments. Normally, there is a coding system used to designate the type of service scheduled and whether or not the customer kept the appointment. For example, the barber may enter the customer's name for a regular cut, the customer's named may be circled for a style and a "b" may be placed by the customer's name to indicate a beard trim. Each salon has its own scheduling and recording procedures.
It is crucial to ask in the initial interview about the types of services provided (cuts, perms, coloring) and the scheduling procedures (walk-ins, set appointments). Also, ask the salon owner about the salon activity, what percentage of each service is customary for that salon and how much activity is normal. The salon owner may remember busy or slow months. Verify the statements by looking in the appointment book and reconcile the statements to the income reported.
Frank, a barber stated that he worked 5 days a week. Reviewing the appointment book, it was determined that he actually worked 6 days a week. However, consistent with his statement, but inconsistent with the appointment book, he reported only income from the operation of 5 of the 6 days.
Another important examination step is to compare the type of services and the number of appointments to the amount of income reported. The salon should have a list of services and prices. Services provided could include: hair cuts, shampoo/style, perms, hair color, nail services, skin care/facials, make-up hair removal, tanning, massage, etc. Compare the services provided with the standard prices. Use the Service Revenue Formula to calculate the average appointment price. By calculating the average appointment price, that amount can be compared to the standard prices changed in the salon. This technique is not an absolute, but can indicate potential income problems.
In addition to the appointment book, a salon or barbershop may also maintain a daily income summary. This should be tested and compared to the appointment book. In some situations, using only the appointment book, the income reported was very close to the correct income. However, in other situations, income was understated. In one case, it was found that the daily income was understated by about $300 due to numerous walk-in appointments not recorded in the appointment book. In that situation, the barber had, however, recorded the correct income in the daily income summary. The point is that while the appointment book is an important document to review, it may not reflect all services actually rendered. Therefore, it is important to analyze it in conjunction with other available records.
Method 4 - Rental Income Formula
Information needed:
 1. Flat rate of rent
 2. Number of Stations
 3. Rent Revenue per Tax Return
Flat Rent Paid times Number of Stations times 52 Weeks equal the Rental Revenue (adjust for vacancy rate)
Analysis of Rent Revenue Reported
Total Rent Revenue Reported divided by 52 Weeks equal's weekly rental revenues
Weekly rental revenues divided by the number of stations equal the amount reported per station.
Example - Rental Income Formula
Information Needed:
 1. Flat Rate of Rent per Station equals $130
 2. Number of Stations equals 10
 3. Rent Revenue per Tax Return equals $65,000
$130 times 10 times 52 equals $67,600
Total Rent Revenue Reported divided by 52 Weeks equal's weekly rental revenues:
$65,000 divided by 52 equals $1,250 per week rental revenue
Weekly rental revenues divided by the number of stations equal the amount reported per station:
$1,250 divided by 10 equals $125 reported per station
Compare the flat rate of rent per station and the reported rate per station. In this particular example, $130 compared to $125 is reasonable. The objective of this comparison is to identify large discrepancies between the flat rate of rent and the reported rate of rent.
Indirect Methods
The Service does not have unlimited discretion to use an indirect method. An indirect method should be used only when the facts of the individual case warrant its use. For example, when:
 1. The taxpayer has no books and records, or incomplete books and records. Incomplete means not sufficient for the examiner to perform a meaningful audit.
 This issue should be documented in the workpapers. If a taxpayer's books and records are inadequate, the examiner should prepare a detailed inventory of the books provided and why they are inadequate. Failure to produce the appointment book for review will usually constitute incomplete records.
 2. The examiner tests the books and records provided by the taxpayer (for example, with a Cash-T method) and determines that they do not accurately reflect income. While use of the Cash-T method may not always, in itself, be used as evidence of the correct tax liability, it can be used a basis, or justification, for the Service to reconstruct the taxpayer's income using an indirect method.
Identification of likely sources of unreported income is generally necessary for the Service to sustain an indirect method of deficiency. In the case of salons and barbershops, like most cash intensive businesses, the most likely source of unreported cash or other unreported service, retail or rental revenue is the business itself. Courts have upheld the Service in situations in which the taxpayers have likely sources of income and no books and records. Careful documentation of the investigation is essential in sustaining a deficiency in such a case.
Employee VS. Independent Contractor
This section discusses the common law factors and relief under Section 530, State Regulatory Authority, revenue rulings, and court cases.
Common Law Factors
The question of whether an individual is an independent contractor or an employee is determined based upon consideration of the facts and application of the law and regulations in each particular case.
See Professional & Executive Leasing V. Commissioner, 89, T.C. 225, 232 (1987), aff'd 862 F.2d 751 (9th Cir. 1988); Simpson v. Commissioner, 64 T.C. 974m 984 (1975). Guides for determining the existence of that status are found in three substantially similar sections of the Employment Tax Regulations; namely, section 31.3121(d)-1, 31.3306(i)-1, and 31.304(c)-1, relating to the Federal Insurance Contributions Act (FICA), the Federal Unemployment Tax Act (FUTA), and federal income tax withholding, respectively.
In general, it should be noted that section 3121(d) (2) of the Internal Revenue Code requires the application of the common law rules in determining the employeremployee relationship. In determining whether an individual is an

Ithaca, N.Y.-"In terms of speed and the breadth of material now accessible to anyone in the world, this is really revolutionary," says audio curator Greg Budney, describing a major milestone just achieved by the Macaulay Library archive at the Cornell Lab of Ornithology. All archived analog recordings in the collection, going back to 1929, have now been digitized and can be heard at _URL_
. "This is one of the greatest research and conservation resources at the Cornell Lab," said Budney, "and through its digitization we've swung the doors open on it in a way that wasn't possible 10 or 20 years ago."
It took archivists a dozen years to complete the monumental task. The collection contains nearly 150,000 digital audio recordings equaling more than 10 terabytes of data with a total run time of 7,513 hours. About 9,000 species are represented. There's an emphasis on birds but the collection also includes sounds of whales, elephants, frogs, primates, and more.
"Our audio collection is the largest and the oldest in the world," explained Macaulay Library director Mike Webster. "Now, it's also the most accessible. We're working to improve search functions and create tools people can use to collect recordings and upload them directly to the archive. Our goal is to make the Macaulay Library as useful as possible for the broadest audience possible."
The recordings are used by researchers studying many questions, as well as by birders trying to fine-tune their sound ID skills. The recordings are also used in museum exhibits, movies, and commercial products such as smartphone apps. For example, a reserve manager in Africa could use the recordings to train staff to conduct an acoustic survey. A teacher could pull out the sounds of ten birds found on the school grounds and create an interactive learning tool for her students. And a sound engineer working on a movie could find just the right sound to create that proper mood.
"Now that we've digitized the previously archived analog recordings, the archival team is focusing on new material from amateur and professional recordists from around the world to really, truly build the collection," Budney said. "Plus, it's just plain fun to listen to these sounds. Have you heard the sound of a walrus underwater? It's an amazing sound!"
Sample some fascinating Macaulay Library sounds:
- Earliest recording: Cornell Lab founder Arthur Allen was a pioneer in sound recording. On a spring day in 1929 he recorded this Song Sparrow sounding much as they do today.
- Youngest bird: This clip from 1966 records the sounds of an Ostrich chick while it is still inside the egg-and the researchers as they watch.
- Liveliest wake-up call: A dawn chorus in tropical Queensland, Australia is bursting at the seams with warbles, squeals, whistles, booms, and hoots.
- Best candidate to appear on a John Coltrane record: The indri, a lemur with a voice that is part moan, part jazz clarinet.
- Most spines tingled: The incomparable voice of a Common Loon on an Adirondacks lake in 1992.
- Most likely to be mistaken for aliens arriving: Birds-of-paradise make some amazing sounds-here's the UFO-sound of a Curl-crested Manucode in New Guinea.
- Most likely to be mistaken for your dog: Three walrus pups bellowing in an uncanny canine cacophony.
- Most erratic construction project: the staccato hammering sounds of a walrus under water

Swedish explorer Peter Lindberg has discovered what he believes to be a UFO at the bottom of the Sea. He states the object is perfectly round, about 60 ft in diameter and unlike anything he has seen in his 18 years of research. The object was discovered between Finland and Sweden on the Ocean floor about 300 ft down. His team has found submerged treasure using sonar, including a century old shipwreck with rare and valuable champagne. Could his team have discovered a UFO wreck? Part of me remains incredulous but after watching the video and seeing the pictures I have to admit, the thing doesn't only look out of this world, but looks just like what a saucer shaped UFO would look like if it somehow ended up on the Ocean bottom. I've heard some people speculate that UFOs energy fields are disrupted by airplanes and helicopters and could cause them to crash. Some say this is what happened with the crash in Roswell. If it is a UFO crash in the Ocean, I hope the aliens hitched a ride and got to safety? Do you think it could be a UFO? If it is, how did it get there? Can aliens travel through the Ocean? What else could it be?

Canopy Layer
Canopy Layer
The Canopy Layer is the second highest layer of the rainforest.
This is where most of the trees grow to, at around 30-45 metres high.
As most trees grow to this height in the rainforest, the leaves tend to overlap each other and the branches tend to wind around each other.
As the leaves of the trees in the Canopy Layer are so thick and big, and overlap each other so much, they block a lot of sunlight going down below.
However, these trees themselves get lots of sunlight.
This layer sees lots of fruit and nuts growing on them, which means lots of rainforest animals live her.

LONDON, England (CNN) -- As an organization they're used to investing billions of dollars in scientific experiments that further our knowledge of earth and space. But the only bill to speak of on this occasion is orange and attached to the body of a rubber duck.
Scientists from NASA hope that rubber ducks will help them better understand glacier movements.
In the name of climate change science, researchers at NASA have dropped 90 rubber ducks into holes of Greenland's fastest moving glacier: the Jakobshavn Glacier in Baffin Bay.
Scientists remain unsure as to why glaciers speed up their movement in the summer months and it is hoped that the rubber ducks -- labeled with the words "science experiment" and "reward" in three languages, along with an email address -- will shed some light on the phenomenon.
One theory is that the summer sun melts ice on the surface of the glacier which creates pools of water which then flow into moulins -- narrow tubular shafts in the glacier. These then transport the water from the top to the underside of the glacier.
It's thought that this base water acts as a lubricant to speed up the movement of the glacier towards the sea.
It is hoped the ducks will help show how the water moves through the ice.
In conjunction with the ducks, Nasa has also launched a GPS probe which they hope will tell them more about the inner workings of the glacier.
So far, neither the probe nor any of the ducks have turned up.
Alberto Behar of NASA's Jet Propulsion Laboratory in California told Reuters: "We haven't heard back but it may take some time until somebody actually finds it and decides to send us an e-mail that they have found it."
The Jakobshavn Glacier is responsible for seven percent of all ice which is peeling off Greenland and its ice sheets could contribute to sea levels rising this century.
The glacier's menace was also felt last century. Experts believe that it was the source of the iceberg which sank the Titanic in 1912.
It's not the first time rubber ducks have helped scientists track water flows. Thousands fell into the sea in 1992 when a container ship bound for Seattle from China shed its load in a storm in the Pacific Ocean. The ducks spent years at sea and washed up in all corners of the globe, telling oceanographers much about the surface currents of the oceans.

The procedure works with Windows 8 or any other Windows actually, it's not Windows 8 exclusive:
 1. Once installed the operating system in the virtual machine install VMware Tools (with the VM running click on the VM menu and select to install VMware Tools). It'll mount an image in one of your CD/DVD drivers.
 2. Start the installation program within the virtual machine:
 Starting the installation program
 3. Once installed you'll be prompted to reboot the machine, do so.
 4. After the reboot you'll see that there's a new icon by the clock in the classic desktop, it denotes that VMware Tools (they enhance the performance of the virtual machine's guest operating system and improve its management).
After that you'll be able to transfer files and folder from and to the VM's operating system by drag and drop for example.
A more permanent way is to setup shared folders between both machines. In the Options tab of the virtual machine settings dialog you can setup folder mappings between both OSs, and even specify if they're to be read only:
Shared folder options
Since the guest OS is Windows selecting to map them as network drivers will make them appear in Computer just like any other:
Access to mapped folders
If you don't wish to map them as a network drive you can access your shared folders over network:
\\vmware-host\Shared Folders\shared_folder_name
Access shared folders via network
share|improve this answer
You can do it from Settings, Just follow the steps,
 - Go to Edit > Virtual Machine Settings > Options and click Shared folders.

A Heligan pineapple.
A fruit produced in the Lost Gardens of Heligan in Cornwall, England, may just be the most expensive pineapple in the world.
The gardeners at Heligan, who began restoration of the derelict gardens in 1990, first purchased fruits for the Pineapple Pit in 1994. Utilizing the same techniques used 70 years ago, during Heligan's heyday, Heligan's Productive Gardening Team produced a miniature pineapple that was, according to the gardeners, "the most delicious pineapple flavour ever tasted."
The "hotbed" technique used in the Pineapple Pit involves heating 30 tons of straw and horse manure through glass. The team was lucky enough to locate the proper mixture of straw and horse manure at a stable near Falmouth, about an hour from the gardens.
While the price of a modern day Heligan pineapple is yet to be announced, the original Heligan pineapples are estimated to have cost the Victorian equivalent of $15,000 to produce.
After the first fruit was tested by Heligan's gardeners, the second was delivered, by hand, to the Queen.

A dual reaction-mass dynamic vibration absorber for active vibration control
MetadataShow full item record
Traditional dynamic vibration absorbers (DVAs) consist of a mass-spring-damper system and are an effective means of attenuating structural vibration over a narrow frequency band. The effective bandwidth of the DVA can be increased by the addition of an externally controlled force, generally applied between the reaction-mass and the primary structure. Such devices are known as hybrid DVAs. This thesis presents a new hybrid DVA configuration which utilizes two reaction-masses in parallel. On this proposed hybrid dual-mass (DM) DVA, the control force is applied between the reaction-masses. It is shown that in broadband control applications, the proposed DM-DVA requires less control force to achieve the same primary attenuation as the traditional hybrid single-mass (SM) DVA. The hybrid DM-DVA was compared to the hybrid SM-DVA with two tests. A numerical simulation of the hybrid DVAs attenuating a single-degree-of-freedom structure was performed. To achieve an equal amount of primary attenuation, the hybrid SM-DVA required 65% higher root-mean-square (RMS) control effort than the hybrid DV-DVA. The numerical model also demonstrated that the hybrid DM-DVA was less sensitive to changes in the system as compared to the hybrid SM-DVA. Additionally, a prototype hybrid DVA was built which could be configured as either the hybrid SM or DM-DVA. The prototype hybrid DVA was used with the feedforward Filtered-X LMS algorithm to control the vibration of a fixed-free beam. The hybrid SM and DM-DVAs attenuated the primary response by a factor of 11.5 and 12.3, while requiring control efforts of 4.9 and 2.7 V/N RMS, respectively. Thus, the hybrid DM-DVA required 45% less control effort while yielding a higher attenuation ratio in this experiment. These results demonstrate the superior performance of the proposed DM-DVA for broadband control applications as compared to the traditional SM-DVA.

Bright Tips for Seniors to Combat the Winter Blues
Alegre home care San Francisco
Winter can be a difficult time for anyone, due to the cloudy days, wet weather, and cold temperatures that typically accompany the season. However, these issues are oftentimes more severe for seniors. Moods can so quickly fall during a rainy winter in San Francisco, which is why it's essential for seniors to do all they can to combat the winter blues. Thankfully, there are a myriad of useful tips that help to facilitate better moods and an increase in happiness.
Why Winter Weather is Extra Difficult for Seniors
For seniors, winter weather is extra difficult than it is for people who are young and more able bodied, though this is mitigated somewhat when making use of a home caregiver. The cold and wet winter weather in the San Francisco Bay Area can really put a damper on the moods of older people. There are a number of reasons as to why, the most obvious of which is simply because the cloudy and gray skies automatically put a damper on anyone's mood.
Colder temperatures can worsen chronic pain conditions to the point where it can simply be difficult to get comfortable at all. This can have a debilitating effect on seniors who already have limited mobility. It's also important to understand that having to stay indoors on a more consistent basis creates feelings of isolation and loneliness that aren't nearly as big of an issue during other times of the year. This is just a small sample of the many reasons as to why winter weather is extra difficult for seniors. Additional factors include:
 - Seniors are likely to exercise less frequently during this season
 - Over-eating for comfort is common
 - The bad weather leads to a more sedentary lifestyle, which exacerbates medical conditions
 - Isolation from being indoors leads to less social time
 - The cold weather affects medical ailments and can make it difficult to sleep
Common symptoms that point towards the onset of the winter blues include sadness, tiredness, and fatigue. To combat the effects that this season may have, make sure to practice some of the following tips.
Exercise is an essential component to a person's happiness. Even light walking 30 minutes per day for five days a week will assist greatly in the reduction of feelings of mild to moderate depression. Walking at a fast pace for 60 minutes a day around three times per week will also help with this, but it will depend on the senior's capabilities. A home caregiver or family member can offer assistance. It's recommended that seniors at least attempt to exercise outdoors during days when it's sunny.
Bright light, in general, has been found to improve mental health, reduce depressive symptoms, and help with social functioning. If support is needed, exercise can even be done alongside a home caregiver. For seniors who can't get outside, consider working out indoors. While this isn't quite as beneficial as as exercising outdoors, it can still lessen mild depression during the winter season.
Listen to Music
Studies have shown that listening to upbeat music on a regular basis can do wonders for a person's mood. These benefits apply both in the short term and long term. During the cold and wet winter months, it can be difficult to get outside. Because of this, it's essential that seniors find activities that can keep them energized and happy. Listening to music is an easy activity that can be done alone or with others. It may even inspire some dancing! Either way, it's an activity that will help combat the winter blues.
It's important that senior s are able to get out of their home as much as possible during the winter months, even if this can only happen on occasion. There are many wonderful ways to volunteer throughout the winter season, from handing out toys to children that are in need to volunteering at a soup kitchen. For those who are able bodied, these activities can be done by both the senior and their home caregiver. Volunteering throughout the winter season will provide an emotional boost that may be needed when experiencing feelings of loneliness and depression. For seniors who are homebound, sending care packages to children in need is also a great way to volunteer.
Engage in Social Activities
As touched upon in the last tip, getting out of the house can really help boost a person's happiness during the cold months of winter. In the San Francisco Bay Area, there are many social activities that seniors can participate in. These activities include everything from going out to eat with an old friend to bowling. Keeping a relatively packed social calendar during the winter season can provide a much needed boost of energy. A home caregiver can help facilitate outings and social time with friends and family members.
Maintain a Healthy Diet
Colder temperatures and dark, cloudy days have the unfortunate effect of causing many people to crave unhealthy foods and carbohydrates. Eating too much food can have negative effects, such as weight gain, which only serves to increase feelings of sadness and depression. Eating a healthy diet that's balanced with a good amount of exercise will keep spirits up and assist in combating the winter blues. Soups that are high in protein and vegetables are some of the most important foods for seniors because they are both nutritional and warming on cold days.
Chase Away Those Winter Blues!
By following each of the aforementioned tips, seniors will be able to effectively reduce and even eliminate the adverse emotional effects caused by winter. These solutions are more readily tackled with the assistance of home caregiving. Home care allows seniors to maintain a sense of independence and allows them to maintain familiar routines. Exercising, volunteering, and partaking in regular social activities are easier to accomplish when a home caregiver is helping with these tasks.

Dracula may not have been able to tolerate sunlight, but some nocturnal bat species may actually rely on the sun for navigation. A study this week in PNAS shows that the greater mouse-eared bat (Myotis myotis) calibrates its internal geomagnetic compass using cues from the setting sun.
At sunset, the researchers exposed bats to a magnetic field rotated 90° east from its normal orientation. The bats, which were displaced from their home range and released in a completely new setting, flew in a direction 77.6° counterclockwise from the actual direction of their roost. Control bats, which had been exposed to a normal geomagnetic field, flew directly toward home.
In the second phase of the study, another experimental group of bats was exposed to a similarly-skewed geomagnetic field, but only after the glow from the setting sun had disappeared. In this treatment, both experimental and control bats flew directly toward their roosts. Taken together, these two experiments show that the timing of the calibration is vital, and the bats must be taking some cue from the setting sun.
Greater mouse-eared bats are nocturnal and generally emerge from their roosts after the sun sinks below the horizon, but before the residual light in the sky disappears. Their nocturnal strategy makes it rather surprising that the sun—rather than the stars, as previously thought—calibrates their navigational systems. The next step in the scientists' research plan: to figure out what aspect of the sunset the bats are using as a cue.

Angela WanhallaDr Angela Wanhalla
Raised in a house full of books and aware of her whakapapa, lecturer Angela Wanhalla knew she'd follow a history path.
"Dad was always interested in history and I knew where I came from, so history became part of the trajectory."
Of Ngāi Tahu descent (Taumutu and Otakou), Angela grew up in the small Canterbury town of Rolleston.
While the subject history was dead certain, Angela took time to fine-tune her specific fields of interest. For her first degree - a BA(Hons) from the University Canterbury - she took papers in Māori history, education, sociology and anthropology, before choosing feminist history for her honours project and MA.
Today, Angela specialises in the histories of cultural encounter in New Zealand's colonial past, with a focus on the history of interracial relationships and intermarriage in New Zealand. She's writing a book based on her PhD, which explored the history of interracial marriage between 1830 and 1940 in a community based at the Taieri Native Reserve.
With postdoctoral studies under her belt (she researched intermarriage in the Canadian prairies at the University of Saskatchewan), Angela's teaching focus at Otago is comparative indigenous histories. This includes teaching papers that introduce students to New Zealand history from a comparative perspective, and take a biographical approach to Māori history.
Dry facts it's not - history is about people's interaction with the world around them, she says.
"It's about reviving and reconstructing communities and looking at personal experiences."

text: Most Americans are now in some form of managed care plan that restricts access to services in order to reduce costs. It is difficult to determine whether these restrictions affect health because individuals and firms self-select into managed care. We investigate the effect of managed care using a California law that required some pregnant women on Medicaid to enter managed care. We use a unique longitudinal database of California births in which we observe changes in the regime faced by individual mothers between births. We find that Medicaid managed care reduced the quality of prenatal care and increased low birth weight, prematurity, and neonatal death.


Q and A
At Lytton Advisory we say that providing commercially oriented economic solutions is all about 'where infrastructure meets money'. In this Q and A, Lytton Advisory Principal Craig Lawrence explains what this means.
Q: So who are economists and what do they do?
A: Economists working with Lytton Advisory are typically postgraduate qualified professionals. We study, develop, and apply theories and concepts from applied microeconomics and write about economic policy. We study the firm and how its commercial operation affects its financial performance, as well as how groups of firms within an industry compete against one another, and how an industry meets the needs of a market.
Q: How does that relate to the development of infrastructure?
A: Because benefits are spread out over a long time and across a wide range of stakeholders. If all the benefits and costs were accrued in one year we could easily see whether the infrastructure was delivering and how risk was defined.
Q: Is it ever that simple?
A: No. Large capital costs of investing in economic infrastructure are recouped through small amounts of use by large numbers of stakeholders over a long period of time. Economic analysis helps identify where the risks are in building and operating infrastructure, ensuring risk is properly attributed to those best able to handle it. Invariably there are also significant social and environmental impacts that need to be considered.
So we help figure out:
 1. Why specific economic and social infrastructure is required and how users may benefit
 2. What infrastructure can cost to build, operate and maintain
 3. How external factors such as exchange rates, interest rates and technology impact on infrastructure project economics
 4. Whether infrastructure provides a sufficient rate of return to its owners, governing authorities and the wider community, as well as identifying in what form that return occurs – financial, economic, social, or environmental
 5. Who is best placed to bear the various risks around building and financing infrastructure
Q: When do you get involved in an infrastructure project?
A: We provide front-end advice and clarity before anybody even starts building; we do mid-project evaluation to ensure that the project remains commercially and economically valid; and we do post-project evaluation to ensure that infrastructure continues to deliver the right results.

We have a database that stores events. Events are generated at a 1000 per sec rate. We need to keep these events accessible for some years.
Usual use of these events is selecting some of them from the last 1-2 months.
Each event corresponds to a resource_id (estimated 5000).
Since just keeping all these in one table gets all maintenance and selects quite slow and resource consuming I was thinking on improving it in some ways:
a) separate every resource_id to each table. 5000+ tables. Selects from multiple resource_ids (maximum 100) will need some rewrite and unions or something.
b) separate every day to a different table. unions or something would be required when selects will require data from multiple days.
c) both the above (too extreme I think)
d) partitioning in someway on timestamp index and maybe even resource_id index. Is it worth it? Or "manual" partitioning of above suggestions is better?
The database is PostgreSQL.

We have something simular, ~5000 events per seconds. Tables are partitioned by month and we store 5 years of data. That gives us a 60 partitions, works fine. It runs on PostgreSQL version 9.1, works better than any older version when using partitions.
EXPLAIN and EXPLAIN ANALYZE are your best friends to get your queries right.

This is a classic case for rolling partitions (or sliding window partitions). Before redesigning the table in thousands of children tables and rewriting your code please give a try to partitioning, like Erwin already advised.

Friedrich von FlotowArticle Free Pass
Friedrich von Flotow, (born April 26, 1812, Teutendorf, near Lübeck, French Empire [now in Germany]—died Jan. 24, 1883, Darmstadt, Ger.), German composer, active mainly in France, who was best known for his opera Martha (1847).
Originally intended for a diplomatic career, from age 16 Flotow studied music in Paris with Anton Reicha. Forced to leave Paris during the July Revolution of 1830, he went home but returned to Paris in 1831. In 1837 he produced a first, brief version of the opera Alessandro Stradella, which later, in its complete form, enjoyed great success. In 1839 he collaborated with Albert Grisar and Auguste Pilati on Le Naufrage de la Méduse ("The Wreck of the Medusa"). Between 1840 and 1878 he produced 19 light operas. Martha, composed to a German libretto and first performed in Vienna, was subsequently heard in translation in many European cities. One of its numbers, in the English version, is "
The Last Rose of Summer." Appealing in its melodic charm, Martha won a lasting place in the operatic repertory. Flotow also wrote ballets for the court theatre at Schwerin, of which he was director from 1855 to 1862, and incidental music for William Shakespeare's The Winter's Tale.

, but to the type! This is sometimes confusing, because one usually uses the same name for the rules and the types. That is if we had named the type for events differently like in the following the cross references needs to be adapted as well:
Transition :
 event=[MyEvent] '=>' state=[State];
Event returns MyEvent :....;
Looking at the syntax definition of cross references, there is an optional part starting with a vertical bar followed by 'CrossReferenceableTerminal'. This is the part describing the concrete text, from which the crosslink later should be established. By default (that's why it's optional) it is "|ID".
Have a look at the linking section in order to understand how linking is done.
By default the object to be returned by parser rule is created lazily on the first assignment. Then the type of the EObject to be created is determined from the specified return type (or the rule name if not explicit return type is specified). With Actions however, creation of EObject can be made explicit. We have two kinds of Actions:
If at some point you want to enforce creation of a specific type you can use simple actions. Example :
MyRule returns TypeA :
 "A" name=ID |
 {TypeB} "B" name=ID;
In this example TypeB must be a subtype of TypeA. If an expression " A foo " is parsed an instance of TypeA is created as soon as the assignment is evaluated. An expression "B foo" would result in creation of TypeB.
Unassigned rule calls
We previously explained, that the EObject to be returned is created lazily when the first assignment occurs or when a simple action is evaluated. There is another way one can set the EObject to be returned, which we call an "unassigned rule call".
Unassigned rule calls (the name suggests it) are rule calls to other parser rules, which are not used within an assignment. If there is no feature the returned value shall be assigned to, the value is assigned to the "to-be-returned" reference.
With unassigned rule calls one can, for instance, create rules which just dispatch between several other rules:
AbstractToken :
 TokenA |
 TokenB |
As AbstractToken could possibly return an instance of TokenA, TokenB or TokenC its type must by a super type to these types. It is now for instance as well possible to further change the state of the AST element by assigning additional things. Example:
AbstractToken :
 (TokenA |
 TokenB |
 TokenC ) (cardinality=('?'|'+'|'*'))?;
Thus, to state the cardinality is optional (last question mark) and can be represented by a question mark, a plus, or an asterisk.
Actions revisited
LL parsing has some significant advantages over LR algorithms. The most important ones for Xtext are, that the generated code is much simpler to understand and debug and that it is easier to recover from errors and especially Antlr has a very nice generic error recovery mechanism. This allows to have AST constructed even if there are syntactic errors in the text. You wouldn't get any of the nice IDE features as soon as there is one little error, if we hadn't error recovery.
However, LL also has some drawbacks. The most important is, that it does not allow left recursive grammars. For instance, the following is not allowed in LL based grammars, because "Expression '+' Expression" is left recursive:
Expression :
 Expression '+' Expression |
 '(' Expression ')'
Instead one has to rewrite such things by "left-factoring" it:
 Expression :
 TerminalExpression ('+' TerminalExpression)?;
 TerminalExpression :
 '(' Expression ')' |
In practice this is always the same pattern and therefore not problematic. However, by simply applying Xtext's AST construction we know so far like so...
 Expression :
 {Operation} left=TerminalExpression (op='+' right=TerminalExpression)?;
 TerminalExpression returns Expression:
 '(' Expression ')' |
 {IntLiteral} value=INT;
... one would get unwanted elements in the resulting AST. For instance the expression " ( 42 ) " would result in a tree like this:
Operation {
 left=Operation {
 left=IntLiteral {
Typically one would only want to have one instance of IntLiteral.
One can solve this problem using a combination of unassigned rule calls and actions:
 Expression :
 TerminalExpression ({Operation.left=current} op='+' right=TerminalExpression)?;
 TerminalExpression returns Expression:
 '(' Expression ')' |
 {IntLiteral} value=INT;
Hidden terminal symbols
Because parser rules describe not a single token, but a sequence of patterns in the input, it is necessary to define the interesting parts of the input. Xtext introduces the concept of hidden tokens to handle the "noise" like whitespaces, comments etc. in the input sequence gracefully. It is possible to define a set of terminal symbols, that are hidden from the parser rules and automatically skipped when they are recognized. Nevertheless, they are transparently woven into the node model, but not relevant for the semantic model.
Hidden terminals may (or may not) appear between any other terminals in any cardinality. They can be described per rule or for the whole grammar. The grammar org.eclipse.xtext.common.Terminals comes with a reasonable default and hides all comments and whitespace from the parser rules.
If a rule defines hidden symbols, you can think of a kind of scope that is automatically introduced. Any rule that is called from the declaring rule uses the same hidden terminals as the calling rule, unless it defines other hidden tokens itself.
Person hidden(WS, ML_COMMENT, SL_COMMENT):
 name=fullname age=INT ';';
 (firstname=ID)? lastname=ID;
The sample rule "Person" defines multiple-line comments (ML_COMMENT), single-line comments (SL_COMMENT), and whitespaces (WS) to be allowed between the fullname and the age. Because "Fullname" does not introduce another set of hidden terminals, it allows the same symbols to appear between 'firstname' and 'lastname' as the calling rule "person." Thus, the following input is perfectly valid for the given grammar snippet:
John /* comment */ Smith // line comment
 /* comment */
 42 ;
To see a list of all default terminals like WS look up Language Inheritance.
Meta-Model inference
The meta model of a textual language describes the structure of its abstract syntax trees (AST).
Xtext uses Ecore EPackages to define meta models. Meta models are declared to be either inferred (generated) from the grammar or imported. By using the 'generate' directive, one tells Xtext to derive an EPackage from the grammar. All elements/types can occur multiple times, but are generated only once.
Type and Package Generation
Xtext creates
an EPackage
 - for each generated package declaration. After the directive generate a list of parameters follows. The name of the EPackage will be set to the first parameter, its nsURI to the second parameter. An optional alias as the third parameter allows to distinguish generated EPackages later. Only one generated package declaration without an alias is allowed per grammar. The aliases have to be unique among every generated EPackage.
an EClass
 - for each return type of a parser rule. If a parser rule does not define a return type, an implicit one with the same name is assumed. You can specify more than one rule that return the same type but only one EClass will be generated.
 - for each type defined in an action or a cross-reference.
an EEnum
 - for each return type of an enum rule.
an EDatatype
 - for each return type of a terminal rule or a datatype rule.
All EClasses, EEnums and EDatatypes are added to the EPackage referred to by the alias provided in the type reference they were created from.
Feature and Type Hierarchy Generation
While walking through the grammar, the algorithm keeps track of a set of the currently possible return types to add features to.
 - Entering a parser rule the set contains only the return type of the rule.
 - Entering a group in an alternative the set is reset to the same state it was in when entering the first group of this alternative.
 - Leaving an alternative the set contains the union of all types at the end of each of its groups.
 - After an optional element, the set is reset to the same state it was before entering it.
 - After a mandatory (non-optional) rule call or mandatory action the set contains only the return type of the called rule or action.
 - An optional rule call does not modify the set.
 - A rule call is optional, if its cardinality is '?' or '*'.
While iterating the parser rules Xtext creates
an EAttribute in each current return type
 - of type EBoolean for each feature assignment using the '?=' operator. No further EReferences or EAttributes will be generated from this assignment.
 - for each assignment with the '=' or '+=' operator calling a terminal rule. Its type will be the return type of the called rule.
an EReference in each current return type
 - for each assignment with the '=' or '+=' operator in a parser rule calling a parser rule. The EReference type will be the return type of the called parser rule.
 - for each action. The reference's type will be set to the return type of the current calling rule.
Each EAttribute or EReference takes its name from the assignment/action that caused it. Multiplicities will be 0...1 for assignments with the '=' operator and 0...* for assignments with the '+=' operator.
Furthermore, each type that is added to


James Stewart was the first Hollywood star to enlist in the military when he was inducted into the Army in March 1942. Due to having a commercial pilots license, he was accepted into the Army Air Corps (the US Air Force did not yet exist). As a bomber squadron commander, he flew numerous combat missions over Germany and was promoted to colonel by the war's end in 1945. For his bravery and the success of his missions, he received the Distinguished Flying Cross and from the French Government the Croix de Guerre with Palm.
After taking some time off, he returned to Hollywood to make It's a Wonderful Life in 1946.

How surprising is it to discover that a "clowder" really is the word for a bunch of cats? As four bewitching members of a coven put together a brew to summon a groom, readers will discover a whole slew of disturbing new vocabulary words. Cobras, for example, are a "quiver" when they gather together. A group of mice is a very apropos "mischief." Find out more as the witches gather toads, goldfish, worms, and more—only to discover that the desired groom, Brungles himself, is less than willing to find matrimonial bliss.

The Gaspésie has fourteen proud witnesses to history, five of which have been given a second life thanks to the judicious interventions of enthusiasts. Thus, these true sentinels of the sea or their outbuildings have been transformed into museums or tourist information offices.
Discover the Matane and La Martre lighthouses, whose beacons have been lighting the way since 1906. The first lighthouse towers above the area and offers a splendid view of the maritime activities, the windmill park and the Chic-Chocs Mountains, and the lightkeeper's house is a museum as well as a tourist information office. The second lighthouse, which remains operational, still has its original clock components, and the building next to it houses the lighthouse museum and its permanent exhibit.
From the top of the 44 stairs of the Cap de la Madeleine lighthouse, the village, the mountains, the barachois, and the mouth of one of the most beautiful salmon rivers reveal themselves before your eyes. The site also offers several services, and has a shop, and a museum. The Pointe-à-la-Renommée lighthouse, renowned for having traveled a lot, stands in a panoramic setting that is quite breathtaking which is also its original home. This historical site was, thanks to Marconi, a strategic communications centre. The beacons of these lighthouses were lit in 1907.
The Cap-des-Rosiers lighthouse, which stands at 34 meters, is the highest lighthouse in Canada, and navigators can always count on its beacon, which was lit in 1858, to find their way. Firmly planted at the entrance of the Forillon National Park of Canada, this fabulous structure was declared a historic monument.
All these witnesses to maritime heritage know how to make their respective history known through various ways. Now it is up to you to take the trail that will lead you to them…

In 2011, one HSC student made headlines because an intruder into her family hope had strapped a device she was told was a bomb strapped to her neck in an attempt to blackmail her wealthy parents for money.
The man was eventually caught, charged and sent to prison.
Incidents of blackmail are historically prevalent and continue to be so today.
The offence of blackmail in NSW
Section 249K of the Crimes Act sets down a maximum penalty of 10 years in prison for the crime of blackmail, which is where a person makes any unwarranted demand with menaces with the intention of:
- obtaining a gain or causing a loss, or
- influencing the exercise of a public duty.
The maximum increases to 14 years where the person threatens to commit a serious indictable offence, which is any offence that carries a maximum penalty of at least five years' imprisonment.
Examples of serious indictable offences include larceny (stealing), assault occasioning actual bodily harm, robbery etc.
Section 249L explains that a demand with menaces is 'unwarranted' unless the person believes that he or she has reasonable grounds for making the demand and reasonably believes that the use of the menace is a proper means of reinforcing the demand.
'Menaces' is defined by section 249M to include:
- an express or implied threat of any action detrimental or unpleasant to another person, and
- a general threat of detrimental or unpleasant action that is implied because the person making the unwarranted demand holds a public office.
The section makes clear that a threat against an individual does not constitute a menace unless it would cause:
- an individual of normal stability and courage to act unwillingly in response to the threat, or
- the particular individual to act unwillingly in response to the threat and the person who makes the threat is aware of the vulnerability of the particular individual to the threat.
Further, a threat against a Government or body corporate does not constitute a menace unless it would:
- ordinarily cause an unwilling response, or
- cause an unwilling response because of a particular vulnerability of which the person making the threat is aware.
In any event, it is immaterial whether the menaces relate to action to be taken by the person making the demand.
Section 249N defines the terms 'gain', 'obtaining a gain', 'loss' and 'causing a loss'.
A 'gain' is defined as any gain in money or other property, whether temporary or permanent, and includes keeping what one has.
'obtaining a gain' includes obtaining a gain for oneself or for another person.
A loss is a loss in money or other property, whether temporary or permanent, and includes not getting what one might get.
'causing a loss' includes causing a loss to another person.
And finally, section 249O defines 'public duty' as a power, authority, duty or function:
- that is conferred on a person as the holder of a public office, or
- that a person holds himself or herself out as having as the holder of a public office.

African Update on Modern-Day Slavery in Saudi Arabia
January 16, 2016
Again, this is another piece I'm putting up in response to the Saudi's foreign minister, al-Jubair, urging the rest of the world to respect Saudi Arabia's death penalty, 'because it's the law'.
This isn't about the Saudi death penalty, but another blemish on theirs and the world's culture and history: slavery.
It's a piece from the African news show, Africa Update, on present day slavery in Saudi Arabia. The presenter states that although slavery was officially banned in 1962, 300,000 slaves remained after its official abolition. And slavery continues today in the form of the Kafala system, or sponsorship, under which Saudi Arabia imports domestic servants and labourers. These are ruthlessly exploited. They typically work between 15-20 hours a day, with no rest days. If they run away, adverts are placed for their apprehension and return, as in the days of real, open slavery. If they complain or resist, they may suffer brutal maltreatment. Some of these domestic workers have even been killed. The Indonesians banned their people from working in Saudi Arabia after one or two Indonesian maids were killed by their masters. And just as shocking, a Saudi man placed an advert in one of the papers for a male slave he was selling, who had been castrated.
The presenter therefore urges her fellow Africans not to go to Saudi Arabia, unless they have a secure, well-paid job, where they will not be subject to such maltreatment, or have been given professorships at a Saudi university. She wonders how long the Saudis will continue to abuse Africans like this, and states that someone should complain to them.

Income mobility can be viewed as a first-order Markov process, with a matrix of transition probabilities which measure how individuals move from an income status in time t to a new status in time t+1. Direct estimation of transition matrices is difficult, since time series panel data are unavailable and limited data on the distribution of income do not suffice to determine the coefficients mathematically, let alone provide enough degrees of freedom for estimation. In this paper, we show that maximum entropy econometrics offers a feasible way to estimate transition matrices using distributional data from Colombia. Using a cross-entropy estimation method, we make efficient use of prior information about the structure of the transition matrices and how they vary with age. The approach is very flexible, allowing the use of "information" in a variety of forms such as inequality constraints, errors in measurement, and prior estimates. Under weak assumptions about the error generation process, we can derive test statistics based on the likelihood ratio measuring the significance of the estimation. The model fits the data well in that the predicted and actual distributions for period t+1 are close. The results show that there is a large degree of upward mobility in Colombia, especially at the bottom of the income distribution and for the younger age cohorts.

- Dilute-Dense-Semi Dense Phase, Controls and Testing.
Dilute Phase Theory
Dilute phase pneumatic conveying systems, also know as suspension flow, operate on the principle that the solids will be suspended in the conveying line air stream. This is accomplished by metering product into a moving air stream. Dilute phase conveying velocities typically are greater than 3500 FPM and material to air ratios are less than 12 to 1. Individual particles in the air stream will have some separation by their suspension in the air stream.
Dense phase conveying:
Dense phase pneumatic conveying systems operate below the minimum suspension velocity and are characterized by product moving along the bottom of the pipe in slugs or a moving bed. Product is conveyed below its saltation velocity at high differential pressures. Conveying velocities are typically less than 2600 FPM and material to air ratios of up to 100 to 1 are possible. Interaction of the particles in a dense phase system is greater than in dilute phase systems.

Tiny, cute and oh so vulnerable. As thousands of baby Western Toads attempt to navigate life in Chilliwack, British Columbia, they only hope they don't get squished by passing motorists.
All week, these miniature toads have traversed Ryder Lake Road, making an attempt to migrate from the wetlands around the lake where they were born into the surrounding forest, reports the Vancouver Sun.
But doing this requires a trip across one of two local roads for the 800,000 or so babies smaller than a dime, so the Fraser Valley Conservancy has stepped in to help control traffic.
(PHOTOS: Top 10 Miniature Animals)
The conservancy hopes to eventually build costly toad-crossing tunnels to place underneath the roadway, an attempt to increase the survival rate of the babies, which can be as little as 1%. Still, with a female having as many as 16,000 eggs, the Western Toad still has a place in B.C., as evidenced by the toad road crossings.
A conservancy representative tells the Vancouver Sun that during peak migration to expect toads covering 30% of the roads around the lake. And with each crossing taking roughly five minutes, it doesn't help that when the tiny creatures get scared they either freeze or roll over.

Emulsion soft templating of carbide-derived carbon nanospheres with controllable porosity for capacitive electrochemical energy storage
A new approach to produce highly porous carbide-derived carbon nanospheres of 20–200 nm diameter based on a novel soft-templating technique is presented. A platinum catalyst is used for the cross-linking of liquid (allylhydrido)polycarbosilane polymer chains with para-divinylbenzene within oil-in-water miniemulsions. Quantitative implementation of the pre-ceramic polymer can be achieved allowing precise control over the resulting materials. After pyrolysis and high-temperature chlorine treatment, the resulting particles offer a spherical shape, very high specific surface area (up to 2347 m2 g−1), and large micro/mesopore volume (up to 1.67 cm3 g−1). The internal pore structure of the nanospheres is controllable by the composition of the oil phase within the miniemulsions. The materials are highly suitable to be used as supercapacitor electrodes with high specific capacitances in aqueous 1 M Na2SO4 solution (110 F g−1) and organic 1 M tetraethylammonium tetrafluoroborate in acetonitrile (130 F g−1).


The Main Objective In Facility Management And Main Reason For Facility Service
facilities management bristol
facilities management bristol
Facilitators assist businesses in achieving their objectives by assisting the stakeholders involved in achieving the objectives in reaching essential agreements. While the context of facilitation may change, the aim stays the same: to assist parties in reaching agreements that enable them to achieve their objectives. Many facilitators need more than just technical practice to complete this task; they also need facilitator training from a strategic expertise training company. The facilities management bristol will guide the people to manage their business and helps to develop the business further.
Be an active listener:
facilities management bristol
It is difficult to lead a group conversation if you do not listen to the members. Although the goal is to assist a community in reaching its own decision, facilitators must lead the discussion in the right direction a role that necessitates careful listening. Trainees cannot seize opportunities to help the
organization gain insight into its issues unless they actively listen, and they cannot seize opportunities to discuss beneficial or unprofitable facets of the group's outlook unless they actively listen.
 Be an Effective Leader:
A facilitator, unlike an executive, does not lead by order or example, but participants must consider him or her as a representative. Otherwise, the person's capacity to lead the meeting and mediate interactions among participants can be jeopardized. Receiving consulting skills instruction as part of facilitator training will assist facilitators in leading in the right direction.
Manage Group Conflict:
Facilitators are often called upon when group contact breaks down after days or weeks of trying to find an agreement. As a result, they are often tasked with resolving the tension between members who have competing views and have created opposing alliances within the party. The ultimate aim is not to manage the tension, but to assist members in working through it and coming together as a team.
Create Effective Agendas:
The meeting's orderliness and efficiency are partially determined by the policy it serves. A successful agenda can help reduce group tension by keeping members centred on profitable issues and encouraging the facilitator to lead the meeting toward a reasonable outcome, in addition to assisting participants in concluding in an organized manner.
Managing Time:
The facilitator must help members work around the agenda's points in a timely way, no matter how well-tailored the agenda is. If the dialogue remains on a certain subject for too long, or if those people dominate the discussion, reaching a consensus within the planned timeline can be difficult.
Managing Administration:
Since various groups have different dynamics, a facilitator must consider the complexities of a certain community to facilitate the appropriate type of discussion. Some classes, for example, will have specific people, such as senior representatives or administrators, who do most of the talking. In this case, motivating all to contribute fairly will hurt rather than help group dynamics.
Two Main Reason To Use Facility Management:
Facilities administration also includes the accurate and productive management of communications between a company's different subsidiaries. This covers faxes and emails passed from one agency to the next. Mailroom management can be performed either on-site or remotely. In reality, many companies tend to handle their mailrooms from a remote location because it improves security. If conditions necessitate it, mailroom administration should also provide a scanning mechanism to further strengthen internal security.
Facilities maintenance firms are typically considered to be highly dependable and security-aware, which can be extremely beneficial to companies who need extra storage space for storing corporate documents and other classified information. The medical profession, in particular, is known to use facilities management firms to stop recruiting professional IT staff, although those companies may support a wide variety of other industries as well.


text: We propose an approach for estimating the probability that a given small target, among many, will be the first to be reached in a molecular dynamics simulation. Reaching small targets out of a vast number of possible configurations constitutes an entropic barrier. Experimental evidence suggests that entropic barriers are ubiquitous in biomolecular systems, and often characterize the rate-limiting step of biomolecular processes. Presumably for the same reasons, they often characterize the rate-limiting step in simulations. To the extent that first-passage probabilities can be computed without requiring direct simulation, the process of traversing entropic barriers can replaced by a single choice from the computed ("first-passage") distribution. We will show that in the presence of certain entropic barriers, first-passage probabilities are approximately invariant to the initial configuration, provided that it is modestly far away from each of the targets. We will further show that as a consequence of this invariance, the first-passage distribution can be well-approximated in terms of "capacities" of local sets around the targets. Using these theoretical results and a Monte Carlo mechanism for approximating capacities, we provide a method for estimating the hitting probabilities of small targets in the presence of entropic barriers. In numerical experiments with an idealized ("golf-course") potential, the estimates are as accurate as the results of direct simulations, but far faster to compute.


of this, we tried to optimize where we cut the tape so we could splice in power and data without having to solder it directly to the tape itself. We spliced by simply soldering wire together and wrapping the joints in electrical tape.
2. Soldering the Banks
Solder station
Based on our design, we knew each strip would be about 10 5/8″ apart, so we cut and stripped 12″ lengths of three conductor wire to use as jumpers to connect strips of tape in series into banks. Then we soldered the strips together–careful to pay attention to the directionality of the tape–into completed banks.
3. Testing
We found out the hard way that you can almost instantly destroy pixels or even entire strips of tape if you have a power short. A power short really means the positive and negative sides of your DC power are connected somewhere with very low or no resistance. As the resistance approaches zero (a complete short) your current grows towards infinity, or as much as your power supply can push. This surge in power will likely fry an LED or two. You can test for a short but checking resistance (Ω) anywhere on your tape across the positive and negative sides of your power lines.
Tip We discovered that there can be some continuity in the tape across those lines, but we considered anything less than 200 Ω to be a short. We saw as little as 300 Ω of resistance in well-connected tape.
We also double-checked that we had the connections right: data to data, positive to positive, and negative to negative. At some points where you're injecting power, your colors may not line up and things can get a little tricky, so it's worth double-checking.
Finally, we plugged the tape in and powered it up before gluing it to the wall. We would simply wire the input side into the Plink it would be connected to, and ensure we could control the bank from E.L.M. and that everything was working as expected.
Our first test brought a little tear to our eye...
Our first test almost brought us to tears… 😂
4. Gluing the Bank to the Wall
Although the tape does come with a 3M adhesive strip, we found it didn't stick well enough to the painted wall we were attaching it to. We found Gorilla glue gel worked the best.
We used a laser level to mark the vertical line for our strip, laid down some glue, and pressed the strip onto the wall.
5. Connecting Control and Injecting Power
We soldered leads onto the tape before gluing it to the wall since it's much easier to solder on a workbench than once the tape is glued to the wall. We made sure the leads for control and power were plenty long enough, so we simply had to cut, strip and connect them to the Plink or terminal block we set up for that bank.
6. Testing and Mapping
Finally, once the tape was glued on with control and power wired in we did a last test to make sure we had proper control of the bank, including the direction of each strip and full RGB control. We also set the bank to full white to ensure there were no visible voltage drops and if required we injected additional power to maintain a perfect white.
Tip For some reason that I never really dug into, the pixels weren't always addressed completely as expected. Often times most of them would be right in order, but a few pixels would jump to the end of the universe. When you're testing, make sure you address all pixels in the universe if some are missing. You might have to sort of reverse engineer their address to finalize your mapping.
Progress! Part of our completed wall during the install:
Progress! Part of the wall is complete.
You're all set now to start playing media and lighting up those beautiful pixels! I'll talk more about configuration and control in part 3.
