The Myth:
Adding potassium or magnesium to your landscape plants will increase their cold hardiness
The Facts
Several articles have been written recently for gardeners who like to "push the zone" envelope. With winter weather on the way, this information is generally useful for protecting marginally cold-hardy plants, The addition of wood ashes (for potassium) and Epsom salts (for magnesium) was recommended to promote cold hardiness of plants grown outside their normal range.
In particular, potassium is mentioned numerous times as "promoting cold hardiness, disease resistance, and general durability." Some horticultural consultants state "what the potassium does is strengthen the cell walls of the plant and will displace the amount of water in the cells making it harder for them to burst during freezing temperatures."
They also recommend that by adding magnesium for increased cold hardiness is less common on the web, and the rationale behind its use is not clear. Where did these recommendations originate?
We first need to dispel the notion that freezing temperatures cause plant cells to burst. This is a common misconception, but in fact rarely happens in nature. What generally happens is that water freezes in the spaces between the cell walls, and this ice formation draws liquid water from the living cells. The living ells are actually stressed and sometimes killed by the dehydration imposed by water moving into these paces.

 - Before adding any mineral supplement to your landscape, have a soil test done first to determineif deficiencies exist,
 - Addition of chemicals (organic or inorganic) to a landscape where no mineral deficiency exists is a waste of money, time, and resources, and is environmentally irresponsible.
 - There is no conclusive evidence that addition of either potassium or magnesium will increase the hardiness of native landscape species
 - There is no evidence whatsoever that addition of either potassium or magnesium will increase the hardiness of non-native, marginally hardy landscapeplant.
 - To grow marginally hardy species, take advantage of microclimates to maximize their chances for survival.
 - The best strategy for overwintering marginally hardy species is to insulate them and the surrounding soil.
The Myth
Always choose native plants for environmentally sustainable landscaping
The Facts
One of the most populr trends in gardening circles is to use more native plants as our natural ecosystems shrink.
There is a large misconception that native plants are supposed to be be resistant to local pathogens and parasites.
There are some urban areas where many native plants just do not survive (or do so only with substantial maintenance). Such areas can include parking strips, traffic circles, and parking lots: in short, areas with imited soil area and lots of environmental stress. Consider the realities of these landscapes:
Dissimilar layers of topsoils and subsoils with poor drainage and aeration
 - Significant compaction and other physical disturbances as a result of animal, pedestrian, andvehicular traffic
 - Alkaline pH due to leaching of lime from concrete
 - Inadequate or improper fertilizer application
 - Lack of mulch or other soil protection
 - Lack of adequate water in summer months
 - Increased heat load from asphalt reflectance
 - Air pollution
Many of the trees and shrubs native to your region evolved in thin, acidic soils with adequate moisture to maintain soil and plant water status. When these species are installed in urban landscapes with significantly different soil and water characteristics they are challenged by a new set of environmental circumstances.Native, forest plants are excellent choices for unrestricted sites with acidic, well drainedsoils.
 - For sites with limited, alkaline, and/or poorly drained soils, choose species adapted toenvironments with similar soils. Consider especially those species that tolerate clay soils.
 - For sites exposed to increased heat choose species adapted to hot, dry climates that can also tolerate cool, wet winters.
 - Instead of installing large trees into limited sites, considered smaller trees or shrubs, Be sure to protect soils with mulch, especially where foot traffic causes compaction.
 - Site considerations should always dictate plant selection.
The Myth
Wood chips made from cedars will kill landscape plants
The Facts
Many gardeners are reluctant to use cedar wood chips because they will kill plants.When one plant emits toxics that kill other plants this process is called allelopathy. One of the best known allelopathhic plants is the Black Walnut tree. It is believed that plants do this to eliminate competition for water and nutrients.
There is virtually no documented evidence for allelopathic activity in cedars.
 - It is unlikely that wood chip mulches containing cedar will have negative effects on established landscape plants.
 - The allelopathic activities attributed to mulches made from cedar and other species may actually be due to other factors such as nutrient and light limitations.
 - Seeds and seedlings, whether weeds or desirable species, are more sensitive to mulch suppression as they do not have established root systems.

Scientists link ancient Arctic camel to modern breed
OTTAWA (AP) — Ancient, mummified camel bones dug from the tundra confirm that the animals now synonymous with the arid sands of Arabia actually developed in subfreezing forests in what is now Canada's High Arctic, a scientist said Tuesday.
About 3.5 million years ago, Strathcona Fiord on Ellesmere Island's west-central coast would have looked more like a northern forest than an Arctic landscape, said paleobotanist Natalia Rybczynski of the Canadian Museum of Nature in Ottawa.
"Larch-dominated, lots of wetlands, peat," said Rybczynski, lead author of a study published Tuesday in the journal Nature Communications. Nearby fossil sites have yielded evidence of ancient bears, horses, deer, badgers and frogs. The average yearly temperature would have been about 0 Celsius (32 Fahrenheit).
"If you were standing in it and watching the camel, it would have the feel of a boreal-type forest."
The Arctic camel was 30 percent larger than modern camels, she said. Her best guess is it was one-humped.
Although native camels are now only found in Africa and Asia, scientists have long believed the species actually developed in North America and later died out. Camel remains have been previously found in the Yukon.
What makes Rybczynski's find special is not only how far north it was found, but its state of preservation.
The 30 fragments found in the sand and pebbles of the tundra were mummified, not fossilized. So despite their age, the pieces preserved tiny fragments of collagen within them, a common type of protein found in bones.
Analyzing that protein not only proved the fragments were from camels, but from a type of camel that is much more closely related to the modern version than the Yukon camel. Out of the dozens of camel species that once roamed North America, the type Rybczynski found was one of the most likely to have crossed the Bering land bridge and colonized the deserts.
"This is the one that's tied to the ancestry of modern camels," she said.

Estimated Time Until Zero Stock Explained
One of the most popular methods of calculating when you should order is the estimated time until zero stock method. Simply keep your estimated time until zero stock number above your lead time and you're in the safe zone. If it approaches or goes below, then you are running the risk of a stock outage.
It's important to note that it is a primitive method of inventory management and doesn't account well for unexpected spikes in sales.
There are two methods through which you can see the estimated time until zero stock.
- Select "Dashboard" and scroll down until you see SKUs – you can sort them by fastest or slowest moving, and you can see whether a reorder is recommended.
- Select "Reorder Point". Use the "Column" button to activate and deactivate filters – select the "Estimated Time until Zero Stock" filter, and optionally the "Reorder" filter to let the app show you which SKUs you need to reorder.


Top 10 firefighter statistics
If you're interested in starting a career in firefighting, or if you are already employed in that field, you might be interested in reviewing the top ten firefighter statistics. Although firefighting can be dangerous and the hours are long and erratic, it's one of the most rewarding careers you can choose. By becoming either a career firefighter or a volunteer, you're making a valuable contribution to your community and to society at large.
The top ten firefighter statistics as compiled by the National Fire Protection Association:
 1. The estimated number of firefighters working in the U.S. is 1,148,100. Of that number, 335,950 are career firefighters and 812,150 are volunteers.
 2. Firefighter statistics categorized by age group: Age 16-19 (3%), Age 20-29 (21%), Age 30-39 (28%), Age 40-49 (26%), Age 50-59 (16%), Age 60 and over (6%)

My project assumes quite big integration with external webservices. Unfortunately first major service is SOAP and second is REST.
Problem is that there are getting more and more places in the code where for example SOAP callout needs some value from different REST callout. Putting this methods inside one wrapper is impossible for me to test since Apex is allowing only to mock one type of callout at the time (either REST or SOAP).
Question: How to create unit test with mocks for both callouts to achieve 100% code coverage of the wrapper method?
Without getting into specifics ( partially because there aren't any, and also because I've only dabbled in this area ) you want to leverage a pattern called Dependency Injection.
Essentially, the idea is to separate your code & calls so that you can pass the result of a call into a helper class. This lets you create mock results in your test class, and test specific parts of a larger system without needing to make a large number of calls. A very simple example is below.
Response response = Caller.Call(); // Calls rest api
Handler.Handle(response); // Handler calls soap api
// In the test, you can create a "mock" object of a response, and pass that to your handler.
Response testResponse = new Response(... ); // Doesnt call rest api, but has a identical response
Handler.Handle(testResponse); // calls soap api
You might have done something close to this - maybe you have a test which has some json in a certain format, which your code is supposed to get from a webservice. Instead of calling the service, you fake a call, and return this explicit json instead. The idea here is exactly the same!
You'll probably need more than one wrapper, and an overhaul of your code in order to make it testable. This is something thats best designed from the start with testing in mind (which is where test-driven development comes from).
Specifically, on the platform, the Stub API is provided to help mock methods. This would be a good place to start looking & designing around.
Heres a better example of setting up a mock (without the stub api):
public void MakeCall(Caller c) {
 Response r = c.Call(); // rest
// Test class
public interface Caller {
 public Response Call();
public class MyCaller inherits Caller {
 public Response Call() {
 return RestApi.Call(); // Valid call out
public class MockCaller inherits Caller {
 public Response Call() {
 return new Response(... ); // pre-set result - can vary result for mult. tests

Making Eden
How Plants Transformed a Barren Planet
Making Eden is a sweeping history of plant evolution that demonstrates both the development and fragility of plant life.
Natural sciences professor David Beerling's book is a comprehensive evolutionary history that traces the birth and maturity of this planet's plants. Sound and alluring, it exposes readers to phenomena like the remarkable complexity of plants, the genetic commonality that enables an incredible variety of flowers, and the fascinating biological secret behind the resilience of redwood trees that flourish despite their immense size.
One of the book's key focuses is the interrelationship of plants and animals. "Our brains are wired to notice animals, not plants," Beerling writes, yet plant life is "a prerequisite for sustaining a consumer society of land-dwelling animals." He makes a strong case that plants "paved the way for the evolution of terrestrial animals, and ultimately led to the appearance of human beings." Plants were, are, and will continue to be essential to the well-being of human beings, says Beerling.
The text also addresses the negative impact that humans have on plants and the Earth in general. Growing populations and increased agricultural production have imperiled the Earth to the extent that plant species are likely to risk extinction, albeit slow extinction. This reality, in combination with climate change, suggests the need for fundamental change.
One cannot help but be humbled by the sophistication and abundance of nature and plant life promulgated on Earth. That story unfolds with beauty in Making Eden. While David Beerling is cautiously optimistic, he also argues that we must "reject the grim alternative future of sending our emerald planet back to the drab world of the distant past."

Helium mass spectrometer leak detectors are designed to measure the partial pressure of trace amounts of helium passing through small leaks and then display the measurement as a function of leak rate. To ensure the accuracy of the measurement, it is necessary to tune and calibrate the leak detector on a regular basis by introducing a precise flow of helium into the leak detector and comparing the output measurement with the actual flow.
This regulated flow, or leakage of tracer gas, is achieved through the use of a calibrated helium leak standard. Many of today's leak detectors have integrated or built-in calibrated leak standards. Older models of leak detectors, and current models of leak detectors that do not provide automatic calibration, may require an external calibrated leak standard to do the tune and calibration function.
Two common types of commercially available calibrated leak standards are glass permeation and capillary leaks. Glass permeation calibrated leak standards consist of a permeable glass membrane encapsulated in a sealed reservoir that is charged with helium. The helium in the reservoir diffuses through the glass membrane out of the leak and into the leak detector vacuum system.
An important factor to consider when using glass permeation style leaks is the temperature's affect on accuracy. Permeation style leaks have a leakage temperature coefficient of 3 or more percent per degree Celsius. As the operating temperature of the calibrated leak increases, its leakage rate also increases by its temperature coefficient. The temperature at which the leak standard was originally calibrated is typically marked on the side of the leak. This allows the user to compare the ambient temperature at the time the leak is used with the original calibration temperature and to compensate for the difference as required.
Glass permeation leaks are fragile and should be handled with care. If the glass membrane breaks from impact, the helium supply will immediately deplete from the reservoir and the leak will be unreparable.
Capillary-type leak standards are made up of a thin metal or glass capillary tube constructed into a pressurized metal envelope such that the gas from the envelope flows through the capillary tube out of the leak and into the vacuum system of the leak detector. One advantage of capillary type leaks over permeation leaks is that they are less sensitive to temperature changes. The leakage temperature coefficient of a capillary leak is approximately 0.2 percent per degree Celsius. Although capillary leaks are not as fragile as permeation leaks, they do have a capacity to become plugged by solids or vapor condensation.
The accuracy of calibrated leaks incorporating an integral gas supply depends on age. Gas-filled leaks will decrease in value over time as the source of helium leaks out. This applies to both permeation and capillary type leaks. The depletion rate of a calibrated leak depends on its specified leakage rate. A 10-7 or 10-8 standard cubic centimeters per second (sccs) range leak will lose approximately 2% to 3% of its initial leak rate value per year.
The depletion rate of a calibrated leak does not change when the leak is stored with its valve in the closed position. In fact, storing a gas-charged calibrated leak with its valve closed will result in helium buildup within the mechanism of the valve, causing the leak to become inaccurate. A gas-charged leak should always be stored with its valve in the open position.
Aged calibrated leaks can be recertified on a regular basis to keep up with internal or external quality standards. Recertifi-cation involves measuring the leak on a calibrated system and re-labeling it with the new leakage rate, calibration temperature and date of calibration. A typical re-calibration cycle is one year.
Regardless of whether the leak detector calibration is done automatically or manually, or whether it is done with an internal or external leak, the process is the same, in general. The first step in calibration involves tuning the leak detector so that the output signal is optimized for a constant in-flow of helium. This is generally performed by introducing a steady flow of helium into the leak detector vacuum system and then adjusting voltages within the analyzer cell and monitoring the output signal of the leak detector. The voltage values that result in the greatest signal output are set as the standard operating voltages until the calibration routine is re-initiated. Attempting to tune to a leak that is less than 1.0E-9 sccs may result in a "no signal" or "low signal" error message. This is an indication that the available helium flow is too low for the leak detector to do a successful tune adjustment.
After tuning is complete, the calibration routine is run. Calibration involves comparing the tuned output signal with the calibrated leak value and applying a multiplier or gain factor to make the leak detector output or display equal the calibrated leak value. It should be noted that adding additional gain to calibrate a leak detector may also amplify noise and background. Higher gain settings could potentially make the leak detector unstable in the higher sensitivity ranges.
The typical gain factor of a leak detector that is isolated from all external systems depends on the inherent sensitivity of the leak detector. This is a function of the design of the vacuum system and the analyzer cell components. A gain factor that is equal to or near 1.0 is the most appropriate because it indicates that the leak detector design provides enough inherent sensitivity to read a calibrated leak accurately without additional amplification of the tuned signal. A significant change in the typical gain factor of a leak detector may indicate a problem. Monitoring the gain factor on a regular basis is a good way to ensure that the leak detector is clean and working correctly.
It is possible for the gain value to vary as a result of a change in the test configuration. If the leak detector is connected to an external vacuum system during the calibration routine, the pumping action of the external system could divert helium from the calibrated leak away from the leak detector. This is referred to as a split-flow condition. In this situation, a greater gain value would be required to bring the measured value up to the fixed value of the calibrated leak. This is not an indication of a problem with the leak detector; it is the result of the application.
Calibration of modern leak detectors is relatively easy and fast. Many of today's leak detectors have an integrated calibrated leak standard and an automatic calibration feature. Calibrating a leak detector with an integrated leak often involves the push of a single button and a 3 to 5 minute wait period. It is important to warm up the leak detector for at least 30 minutes prior to performing a calibration routine.
The frequency of calibrating a leak detector can depend on the application or be mandated by quality control requirements. More frequent calibrations are recommended for applications that involve accurate and quantitative testing to a specific pass/fail value. Less frequent calibrations are required for qualitative or go/no go testing. A well-designed leak detector will hold its calibration within the tolerances of go/no go test requirements for more than a few weeks. In addition to scheduled calibrations, it is appropriate to perform a calibration after the leak detector has experienced an unexpected shock, such as a power outage, power surge or inadvertent venting of the test port while in high sensitivity mode.
- A regulated flow is achieved through the use of a calibrated helium leak standard.
- Many of today's leak detectors have built-in calibrated leak standards. Older models may require an external calibrated leak standard.
- Two common types of commercially available calibrated leak standards are glass permeation and capillary leaks.


note BrowserUk What most the responses so far seem to have missed is that the cast of the in-ram [split]ing and [join]ing of records, pales into insignificance when compared to the time required for the read-a-record, write-a-record flip-flopping of the read head back and forth across the disk. There are two possible ways to speed up your processing: Overlap the [split]ing & [join]ing with either the reading or the writing (or both). This can be achieved by using two or more threads or processes. Read and write larger chunks of the file to minimise the number of seeks the read heads need to make. Interleaving 80GB/4k = 20 million reads, and (~) 200,000 write means (at least) 400,000 track to track seeks. If you increase the read & write chunk sizes to 1MB each, that can be reduced to ~1,500 track to track seeks. Try these: #! perl -sw use strict; our $B //= 64; $B *= 1024; my $ibuf = ''; while( sysread( *STDIN, $ibuf, $B, length $ibuf ) ) { my $p = 1+rindex( $ibuf, "\n" ); my $rem = substr( $ibuf, $p ); substr( $ibuf, $p ) = ''; open my $RAM, '<', \$ibuf; print while <$RAM>; $ibuf = $rem; } #! perl -sw use strict; our $B //= 64; $B *= 1024; my $obuf; while( <> ) { my _USER_ = split chr(9); $obuf.= join( chr(9), _USER_[2,0,5] ). "\n"; if( length( $obuf ) > $B ) { print $obuf; $obuf = ''; } } print $obuf; ## Corrected C&P error. See [lotus1]'s post below. Usage: ibuf -B=1024 < in.tsv | -B=1024 > out.tsv. Based on my experiments, it might be possible to more than halve your processing time, though YMMV. Experiment with adjusting the -B=nnn (in kbs) parameters up & down in unison and independently to find the sweet spot on your system. Be aware, bigger is not always better. 1024 for both seems to work quite well on my system, anything larger slows it down. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. _PHONE_ _PHONE_

In precise detail, Ali Kazim captures the stillness of a deserted landscape or a sudden transformation as a storm tears through parched terrain. His paintings are based on the Punjab region of Pakistan – once home to a large part of the Indus Valley Civilisation and now scattered with ancient ruins. Kazim regularly visits these ruins, studying the mounds that form the contours of the landscape, and searching the sites of long-abandoned cities, which are partly exposed or still buried.
He draws on a repertoire of techniques and materials to access these emotive surroundings and conjure the mysteries of forgotten cities. The large landscape is informed by Siyah Qalam, a fleetingly popular form of Persian painting influenced by the ink painting traditions of East Asia, whereby multiple layers of ink were applied with a fine brush. Kazim also creates atmospheric compositions on polyester film rendered in pigment with cotton or soft brushes. Stencils and erasers are then used to detail bolts of lightning, and storm and dust clouds, elements that momentarily bring the landscapes to life.
Kazim is also interested in how pottery shards have transformed over centuries from practical objects to remnants of deserted and forgotten places, and the blackened ceramics bear organic lines or veins to resemble both rocks and organs.

GSAS/EXPGUI Alumina example (Intro)
What's this all about?
The goal of Rietveld analysis is to fit a structural model ("crystal structure") to powder diffraction data. To do this requires determining the structural parameters [unit cell, atom positions and displacement (thermal) parameters, etc.] for all crystalline phases present, as well as a variety of instrumental and sample parameters that describe the experimental and sample conditions: scale factors, peak broadening, the background, preferred orientation, etc. In most cases Rietveld analysis is performed to determine the structural parameters, but increasingly, the method is also used to determine relative amounts of the crystallographic phases, the amount and type of peak broadening, the preferred orientation, or similar types of sample characterization.
This exercise provides a tutorial example of how to use the GSAS software package with the EXPGUI interface to perform Rietveld analysis. The material chosen for this exercise, corundum (aka alumina, sapphire or ruby), has a simple structure, so the starting coordinates have been distorted so that there is an improvement obtained by performing the fit. Likewise, this sample exhibited virtually no sample-related broadening, so the instrumental peak profile was altered so that the peak profile terms would not agree with the data, again so that the exercise would demonstrate the sorts of steps needed for typical Rietveld refinements. The tutorial consists of 11 web pages, each has a series of related steps. There are also editorial comments, that explain a point further or explain how these steps might be applied differently in another case. These comments are in specified in italic type.
Rietveld analysis works using non-linear least-squares fitting to optimize (refine) parameters. This means that we must start with approximate values for all parameters that will be fit. We then allow the software to optimize a small subset of the parameters -- a minimal number of parameters that must be fit before any progress can be made. Slowly, additional parameters are selected to be refined, until all parameters in the model (if the data support that) are refined. Despite the simplicity of the material, this exercise demonstrates many of the procedures needed for more complex materials.
EXPGUI and GSAS run on Windows, Linux and IRIX (Silicon Graphics computers). The example figures show in this tutorial were generated in Unix, but virtually all GSAS and EXPGUI operation is identical between Unix and Windows.
Getting Started
To perform this tutorial on your own computer, you will need to have GSAS and EXPGUI loaded on your computer (see installation links on the EXPGUI home page). You will also need three files that are referenced in the following web pages:

What is SAP PI?
SAP PI (Process Integration) is an undertaking joining stage that gives consistent mix among SAP and non-SAP applications inside the association A2A (Application to Application) or even external the association B2B (Business to Business). It permits associations to trade data between inner programming projects inside the organization and outer frameworks outside the organization.The SAP PI full structure is Process Integration.
What is SAP PO?
SAP PO (Process Orchestration) is an instrument for mechanization and streamlining of business processes. It consolidates elements of SAP Business Process Management (BPM), SAP Process Integration (PI), and SAP Business Rules Management (BRM). As such, SAP Process Orchestration is a further developed rendition of SAP PI and has every one of the instruments expected to incorporate applications. The SAP PO full structure is Process Orchestration. Figuring out SAP PI/PO with an Example However, this was a specialized part of SAP PI, yet to comprehend this better we will see the case of execution of SAP Process Integration.
To comprehend the idea of SAP PI all the more plainly, we take an illustration of an enormous scope Dairy Industry, which is working in a huge part of a state and ruling the locale. Be that as it may, there is some limited scale dairy businesses working in a similar district, lined up with the enormous scope industry which isn't creating a gain because of their cost variety contrast with huge scope industry. So to keep away from the valuing struggle and keeping up with a similar value all around the district, enormous scope and limited scope industry choose to connect together, with the assistance of SAP PI. They interconnect with one another with the assistance of SAP PI and began to function as a solitary unit. Presently, through SAP PI they can trade all the data relating to dairy industry, including estimating and share an equivalent measure of benefit.
SAP PI interfaces various stages like
SAP and Non-SAP frameworks
B2B and A2A Scenarios
Offbeat and Synchronous Communications
Cross-part business process the executives
In this SAP PI/PO instructional exercise, we will learn
Why SAP PI/PO?
Before SAP PI, business would associate with one another through highlight point correspondence. In any case, this cycle isn't utilized for various and complex cycles. For smooth correspondence between different organizations, Mediated correspondence or Integration merchant is utilized, and SAP PI adjusts this framework well overall. It empowers interconnection of an alternate interaction by means of a focal area known as Integration Broker, dissimilar forthright to point association which is more similar to a cobweb. The coordination specialist or server is a fundamental piece of interceded correspondence comprise of Java based Advanced Adapter Engine (AAE) and a reconciliation motor for directing. Interceded correspondence depends on a coordination merchant which is executed by trading XML messages.
Significance of SAP PI/PO
SAP PI PO Overview
Let perceive how SAP PI handles the XML messages by the assistance of Integration Broker. The trading of information or message in SAP PI happens in this four stages.
Message Transformation: During message trade, it changes the construction of the business information
Message Routing: Forwarding a message sent by a shipper framework to at least one recipient frameworks
Network Adapters: Connecting the coordination representative and recipient framework, the connector will change the approaching message into an inbound message and later believer it to the configuration of the getting framework at the opposite end
Joining Processes: Cross part Business Process Management (ccBPM) comprises of capabilities for upgraded administration organization.
Next in this SAP PI instructional exercise, we will figure out How SAP PI/PO works.
How SAP PI/PO works
SAP PI carries out three essential roles
Interface: SAP PI has a capacity to incorporate with all application whether or not it is an application from an outsider or from the SAP. It utilizes the connector system to coordinate outsider arrangements. Co-ordinate: It can characterize a way/work process for every deal that is incorporated. It guarantees that each message is accurately conveyed from the source to the objective Convey: It can make an interpretation of documents into any configuration whether an inside record design or any business to business combination standard.Next in this SAP PO instructional exercise, we will find out about SAP PI PO design. SAP PI is certainly not a solitary part liable for the reconciliation of SAP and Non-SAP application, yet a bunch of parts together make SAP PI useful.

Walk Two Moons Summary
Extended Summary
Walk Two Moons has received five prestigious awards, including the Newbery Medal in 1995. The Ohio-born author, Sharon Creech, attributes the title of the book to a message she discovered inside a fortune cookie while she was finishing her manuscript: "Don't judge a man until you've walked two moons in his moccasins." The plot is separated into three separate settings that intermingle throughout the story to illustrate the personal transformation of the lead character, Salamanca Tree Hiddle, known as Sal. She is a thirteen-year-old girl who is homesick for her farm in the fictional town of Bybanks, Kentucky, and who misses her mother with a desperate intensity that dominates the story. The book is framed around a road trip Sal takes with her grandparents from Euclid, Ohio, to Lewiston, Idaho, where her mother fled after a tragic miscarriage and a bout with depression. Sal and her grandparents trace the route her mother took west, visiting the places she described in postcards she sent them.
Throughout the road trip, Sal recalls memories of her mother before she left their home in Bybanks. She also tells stories to her grandparents about the recent disappearance of Phoebe Winterbottom's mother, the appearance of the Lunatic, and her budding romance with a classmate named Ben. In turn, Sal's grandparents relate stories about their own lives and marriage.
Sal's memories of her mother, Sugar, are both sweet and sad. Sal's early memories of her mother reveal a woman who adores her husband, her daughter, and life on their family farm. Sugar loves anything to do with nature, including insects, animals, and sugar maple trees (after which she was named). Of particular importance are the wild blackberries Sal would pick with her mother in the spring. Sugar's kisses often smelled like blackberries, so the berries come to represent her mother to Salamanca, as do the trees for which they are each named.
Sal's parents dream of "filling up the house with children," but when Sugar gives birth to a stillborn daughter and subsequently undergoes an emergency hysterectomy necessitated by complications with the birth, she struggles with her roles as a wife and mother and falls slowly into a depression. Sugar hopes to find relief during a visit to her cousin, so she travels to Lewiston, Idaho. But she does not return. The details of Sugar's experience in Idaho are vague until the last few chapters of the book.
Sal struggles with guilt because of an accident she had the day of the stillbirth, which caused her mother to carry her for a short distance. She also feels guilty because she has an intermittent desire to move on without her mother. Her father's grief proves to be too painful; he moves Sal and himself to Ohio where his new friend, Margaret Cadaver, has found him a new job. Sal is resentful of her father's relationship with Margaret. She attempts to avoid Margaret and her blind, eccentric mother, Mrs. Partridge, when possible. Then Salamanca meets Phoebe.
The girl's friendship begins when Sal spots Phoebe Winterbottom peering from her bedroom window across the street from Margaret Cadaver's house. Phoebe thinks Margaret and her eccentric mother are peculiar and have possibly murdered the late Mr. Cadaver. Because Sal is eager to find fault with the new woman in her father's life, she agrees with Phoebe although her better judgment tells her otherwise.

Title Quality Assurance of Foreign Placement in Europe (QAFP in EU)
Project Number 2012-1-NL1-LEO05-08712
Project Type Transfer of Innovation
The competitiveness of Europe requires an international oriented and skilled workforce. QAFP in EU aims to make a start on creating a European network of regional agencies that will be authorized to assess companies of being a 'learning company' based on agreed criteria and at establishing accreditation agencies and accreditors, at partnerships in this area, expansion of placement companies accredited (and labelled) and expansion of students using accredited companies. Increasing the quality of accreditation and increasing the quality of the 'on the job' - learning environment contributes to the learning process and skills of students.
We focus on the Green Sector. The Dutch VET system requires that students have a substantial amount of practical 'on the job training' (mobility, work experience abroad, and getting insight in live and work) which is provided and executed at accredited companies because accreditation guarantees better the quality of a placement.
The agenda of the EU VET contributes to the competitiveness of Europe, and promotes an international oriented and skilled workforce. All VET sectors in European countries will have to work on increase of mobility, and work experiences abroad. This project, Quality Assurance of Foreign Placement in Europe (QAFPE),stimulates companies all over Europe to create a learning environment of high quality to teach trainees in a effective and efficient way.
The Dutch VET system requires that students have a substantial amount of practical training, and this 'on the job training' (mobility, work experience abroad, and getting insight in live and work) is provided and executed at accredited companies. Accreditation is provided by a National Centre of Expertise as Aequor is and is a guarantee for quality of guidance and practical training. Now the international mobility is stimulated and increasing, we need much more accredited companies in the European member states
model for accreditation of placement companies in Europe and to establish sustainable cooperation of accreditation agencies in Europe.
To realise this objective we work on:
- Development of a network in Europe that can and will accredit placement companies (the network takes care for exploitation and maintenance)
- Development of common criteria, and a common procedure for accreditation of companies (model)
- Monitoring of companies and the quality of work based learning
- To discuss and propose a European label as a qualification of accredited companies
- Expansion of work placement opportunities for students (databank, data exchange), the number of accredited placement companies, and of colleges that open their placement information.
The consortium is constituted with partners experienced in placement opportunities, VET relations, and/or European umbrella organisations related to VET or companies, knowledge centres in 'green' education and program development, or representatives of the 'green' sector'.
- Methodology and procedures for European accreditation of placement companies agreed by involved institutions or authorities that cooperate in a European network
- Report on criteria, protocols, monitoring companies and placements, and recognition of practical learning outcomes
- Increase of interest of companies as a recognised placement company, registration in a cooperative database and more interest of colleges and students for international placements.
QAFPE supports the EC and national authorities to realise in 2020 a high percentage of students with work experience abroad, insight in culture, and language. QAFPE stimulates authorities to accept and recognise the placement (competencies, time, and work experience) because this approach guarantees the quality of work based learning and the number and quality of placement companies will increase.
Recognition, transparency, certification

transparency and certification
The project has ended in February 2015.
The objective of the project was to improve the quality of traineeships abroad. We have developed and tested:
- recognition of learning outcomes of work based learning
- a quality labe 'WBL' (Work Based Learning)
- a model for accreditation presented as Memorandum of Understanding. Over 20 organisations in Europe have agreed with this MoU.
- through Newsletters we have informed our target groups.
- a needs analysis
- a training for employees of Local Agents
- an implementation plan.

text: This work is concerned with the proposition of high contrast multi-layer structure for the fabrication of reflecting surface in the visible range. The multi-layer SiO2/Ta2O5 system has superior heat resistance and reflecting properties. Ta2O5 and SiO2 thin films were prepared by RF plasma sputtering in Ar-O2 mixed gas using Ta2O5 and SiO2 target respectively. Secondary ion mass spectroscopy and SEM observation were performed in order to investigate the multi-layer structure. The XRD and XPS analyses were also performed in order to investigate the crystal structure and the chemical state of the films. The optical constants of Ta2O5 single film were investigated by the ellipsometric analysis. Using the Ta2O5 film doped Bi2O3 for a reflecting multi-layer structure improved the reflecting properties and the heat resistance of the multi-layer system because of the high refractive index of the doped film.

Highway & Rail Transit Tunnel Maintenance & Rehabilitation Manual
2005 Edition
Appendix A: Life-Cycle Cost Methodology
To properly plan for future repairs or scheduled maintenance in a tunnel, it is beneficial to perform a life-cycle cost analysis of the different options involved for each anticipated major repair to ensure the greatest cost efficiency over the life of the tunnel. This process involves evaluating the alternatives over a given duration or economic life to determine specific costs involved for each option and then equating them through a series of mathematical formulas that enable the costs of each option to be compared at a common point in time. The life-cycle costs of a given alternative include all associated costs over the expected life of the option. In general these costs may include:
 - Initial costs - Engineering or design costs, price of equipment, construction costs, etc.
 - Operating/energy costs - Annualized amount to operate (e.g. cost of electricity to run mechanical equipment).
 - Maintenance costs - Annualized costs to maintain equipment or repair minor defects.
 - Rehabilitation costs - Future expense for known procedure at specified time (e.g. certain type of light bulbs may need to be replaced every five years).
 - User costs - Costs associated with impact on the functioning of tunnel (e.g. tunnel may need shut down for repair; therefore, impact to traffic can be shown by applying an annualized cost to each hour tunnel is closed).
 - Salvage value - Sale value of equipment at end of expected life (e.g. mechanical fan or railroad tie may be of some value to others even after it has served its purpose in the tunnel).
There are two main methods for performing a life-cycle cost analysis, namely, the present worth and the annualized methods.
 - 1. Present Worth Method
 As the name implies, this method attempts to bring all of the present and future costs of a given option to present day values. This process should be completed for each major repair/rehabilitation and subsequently the options could be compared. Determining the present worth of a future expense is done by taking into account inflation of the dollar and therefore discounting the amount by a predetermined rate over the period between the future expense and the present time. The present worth of the future expense is also the amount that could be invested today with reinvested interest over the duration to equal the amount of the future expense. An example of a future expense would be the rehabilitation costs mentioned above. The general form of the equation for determining the present worth of a future expense is:
 P = F 1
 ( 1 + i )n
 P = Present worth
 F = Future one-time expense
 n = Number of years
 i = Discount rate
 Future expenses can also be uniform, in that the same expense occurs at the end of each year. An example of this would be the annualized maintenance costs described previously. The general form of the equation for determining the present worth of an end-of-year expense is:
 P = A [ ( 1 + i)n - 1 ]
 [ i ( 1 + i )n ]
 P = Present worth
 A = End-of-year payments
 n = Number of years
 i = Discount rate
 - 2. Annualized Method
 The annualized method is used to transform present and future costs into a uniform annual expense. This annual expense can be compared to the annual expenses of the other repair/rehabilitation alternatives to determine which one is most cost effective. Converting all future expenses into a present value as before and then using the equation below to convert that value into an annual expense will provide a uniform annual cost.
 A = P [ i ( 1 + i )n ]
 [ (1 + i )n - 1 ]
 A = End-of-year payments
 P = Present worth
 n = Number of years
 i = Discount rate
 The above two methods can also be performed without using the actual equations given. Standard economic tables have been developed that give factors that are based on the discount rate and the economic life under consideration. These factors are also unique to the desired result. The procedure for using standard economic tables is as follows:
 - Determine the discount rate (i) and economic life (n) to be used for the analysis. It is important to choose an economic life that is equal for the given alternatives if the present worth method is to be used. Otherwise, the annualized method must be used.
 - Develop a cash flow diagram for each option, which shows all relevant costs described above on a timeline of years in the economic life.
 - Take individual costs, whether uniform or one-time, and insert them in the proper formula given below along with the factor from the appropriate economic table.
 - (P/F,i%,n) - or present worth (P) given future expense (F) at discount rate (i) for number of years (n).
 - (P/A,i%,n) - or present worth (P) given end-of-year payments (A) at discount rate (i) for number of years (n).
 - (A/P,i%,n) - or end-of-year payments (A) given present worth (P) at discount rate (i) for number of years (n).
 Caution must be used in determining the appropriate discount rate. Because of the power of compounded interest, a difference in discount rate can actually change the final outcome of the analysis if the repair/rehabilitation options being considered have different arrangements of uniform and onetime costs. According to Peter Kleskovic who wrote A Discussion of Discount Rates for Economic Analysis of Pavements, a draft report for FHWA:
 "The discount rate can affect the outcome of a life-cycle cost analysis in that certain alternatives may be favored by higher or lower discount rates. High discount rates favor alternatives that stretch out costs over a period of time, since the future costs are discounted in relation to the initial cost. A low discount rate favors high initial cost alternatives since future costs are added in at almost face value. In the case of a discount rate equal to 0, all costs are treated equally regardless of when they occur. Where alternative strategies have similar maintenance, rehabilitation, and operating costs, the discount rate will have a minor effect on the analysis and initial costs will have a larger effect."
 The above procedures will allow the most economical repair/rehabilitation alternative to be identified, but as can be expected, the least costly is not always the best. Therefore further comparison can sometimes be utilized to take into account the "human factors" of the alternatives. In his book entitled Value Engineering: Practical Applications... for Design, Construction, Maintenance & Operations, Alphonse Dell'Isola, P.E., has developed a procedure for weighted evaluation of human factors such as comfort, appearance, performance, and safety along with the economic costs. It is suggested that his procedure or something similar be used if the effects of the human factors are of concern during the economic life of the alternatives.
 - 3. Example
 The following example uses completely arbitrary costs to properly show the benefits of a life-cycle cost analysis.
 Consider a transit tunnel in which the track support system is in need of replacement. Currently the system is ballasted track and can either be replaced with direct fixation slab track or a new, ballasted track system. Costs given to the different options are shown below for every 150 m (500 ft) of track.
 - a) Direct Fixation Slab Track:
 Initial Construction Costs$500,000
 Joint/Crack Sealing (years 10, 20, 30 and 40)$20,000
 Annual Maintenance$1,000
 Estimated Life50 years
 Direct Fixation Slab Track
 - b) Ballasted Track:
 Initial Construction Costs$250,000
 Replacement Ties (years 12 and 24)$200,000
 Annual Maintenance$20,000
 Estimated Life35 years
 Ballasted Track
 - c) Factors from Standard Economic Table (assume 7 percent discount rate)
 - d) Alternate 1 - Direct Fixation Slab Track
 - (1) Present Worth Method
 P =$500,000 + $1,000(P/A,7%,50) + $20,000(P/F,7%,10) + $20,000(P/F,7%,20) + $20,000(P/F,7%,30) + $20,000(P/F,7%,40) - $100,000(P/F,7%,50)
 P =$500,000 + $1,000(13.8007) + $20,000(0.5083) + $20,000(0.2584) + $20,000(0.1314) + $20,000(0.0668) - $100,000(0.0339)
 P =$529,709
 - (2) Annualized Method
 A =$500,000(A/P,7%,50) + $1,000 + $20,000(P/F,7%,10)(A/P,7%,50) + $20,000(P/F,7%,20)(A/P,7%,50) + $20,000(P/F,7%,30)(A/P,7%,50) + $20,000(P/F,7%,40)(A/P,7%,50) - $100,000(P/F,7%,50)(A/P

As we wind down Summer and prepare to say "hello" to Fall days, here are a few ways to play, learn, and explore during the month of September.
Ways to play, learn, and explore in September
September's flower is the Aster. The word "aster" comes from the ancient Greek for "star." Sometimes the aster is called the Michaelmas Daisy. There are some activities and a poem for the Michaelmas Daisy at The Flower Fairies Official website.
While you and your kids are learning about Autumn flowers, why not try your hand at a few of these felt sunflowers from Living Crafts?
The wonderful Se7en has a free printable September calendar for you.
Although September is the ninth month, the word September comes from the Latin "septi" for seven because in the Roman calendar it was the seventh month.
Talk Like a Pirate Day is September 19th (which also happens to be the day after my husband Christopher's birthday, what fun!). Right now you can pick up a copy of Captain No Beard for your kindle for 99 cents from Amazon (you can pick up the printed version, too) – and if you are an Amazon Prime member you can borrow it for free! Love that!
The Autumnal Equinox occurs on September 22nd. The leaves will begin to change colors, the air will become cooler, and the hours of daylight a little shorter.
Here are a few fun leaf-related activities:
Why not try out an Autumn recipe or two with your kids this month?
- Maple Pecan Baked Apples ::: Simple Bites
- Pumpkin Butterscotch Cookies ::: Joy the Baker
- Healthy After-School Snacks: Popsicles ::: Playful Learning
How will you and your kids be playing, learning, and exploring this September?


It has been a few months since I have made a change to the "Generics based Framework for.Net Hadoop MapReduce Job Submission" code. However I was going to put together a sample for a Reduce side join and came across a issue around the usage of partitioners. As such I decided to add support for custom partitioners and comparators, before stamping the release as a version 1.0.
The submission options to be added will be -numberPartitionKeys (for partitioning the data) and -comparatorOption (for sorting). Before talking about these options lets cover a little of the Hadoop Streaming Documentation.
A Useful Partitioner Class
Hadoop has a library class, KeyFieldBasedPartitioner, that allows the MapReduce framework to partition the map outputs on key segments rather than the whole key. Consider the following job submission options:
 -partitioner org.apache.hadoop.mapred.lib.KeyFieldBasedPartitioner
The option specifies that the map output keys will have 4 fields. In this case the the -Dmapred.text.key.partitioner.options=-k1,2 option tells the MapReduce framework to partition the map outputs by the first two fields of the key; rather than the full set of four keys.This guarantees that all the key/value pairs with the same first two fields in the keys will be partitioned to the same reducer.
To simplify this specification the submission framework supports the following command line options:
 -numberKeys 4
 -numberPartitionKeys 2
When writing Streaming applications one normally has to do the partition processing in the Reducer. However with these options the framework will correctly send the appropriate data to the Reducer. This was the biggest change that needed to be made to the Framework.
This partition processing is important for handling Reduce side joins; the topic of my next blog post.
A Useful Comparator Class
Hadoop also has a library class, KeyFieldBasedComparator, that provides sorting the key data. Consider the following job submission options:
 -D mapred.output.key.comparator.class=org.apache.hadoop.mapred.lib.KeyFieldBasedComparator
 -D mapred.text.key.comparator.options=-k2,2nr
Here the MapReduce framework will sort the outputs on the second key field; the -Dmapred.text.key.comparator.options=-k2,2nr option. The -n specifies that the sorting is numerical and the -r specifies that the result should be reversed. The sort options are similar to a Unix sort, but here are some simple examples:
Reverse ordering: -Dmapred.text.key.comparator.options=-r
Numeric ordering: -Dmapred.text.key.comparator.options=-n
Specific sort specification: -Dmapred.text.key.comparator.options=-kx,y
For the general sort specification the -k flag is used, which allows you to specify the sorting key using the the x, y values; as in the sample above.
To simplify this specification the submission framework supports the following command line option:
 -comparatorOption "-k2,2nr"
The framework then takes care of setting the appropriate job configuration values.
Although one could define the Partitioner and Comparator options using the job configuration parameters hopefully these new options make the process a lot simpler. In the case of the Partitioner options it also allows the framework to easily identity the difference in the number of sorting and partitioner keys. This allows the correct data to be sent to each Reducer.
As mentioned, using these options, in my next post I will cover how to use the Framework for doing a Reduce side join.

In years past, grilling usually meant cooking hot dogs, hamburgers, steak, or chicken over charcoal. Among the equipment now available for outdoor cooking are electric, gas, and pellet grills. An unlimited array of food now seems destined for the backyard grill.
Many kinds of seafood are prime candidates for grilling because of their nutritional composition, physical attributes, and flavor. Most seafood is low in fat, which (aside from being less prone to flare-ups) provides a healthy source of high-quality protein. According to the 2020–2025 Dietary Guidelines for Americans (DGA), eating seafood beginning at around 6 months and continuing through all stages of life can be beneficial to health. The DGA encourage adults and children to eat seafood 2 or 3 times a week for the following benefits:
- Seafood consumed regularly during pregnancy can help brain development in babies.
- Seafood starting at age 6 months provides critical nutrients such as iron, omega-3's, and choline that support brain development and immunity for infants and toddlers. Lifelong taste preferences and healthful food choices can also be shaped by introducing seafood early.
- For adults, seafood provides protein, calcium, and vitamin D, which help strengthen bones and maintain muscle mass.
Seafood has smaller percentages of skeletal and connective tissues compared to equal portions of red meats or poultry. This makes seafood fast and easy to grill. Seafood also offers a variety of flavors that can be enhanced during the grilling process. For seafood recipes, visit the Eat Alabama Seafood, The Catfish Institute, and Dish on Fish websites.
Grillable Alabama Seafood
Whether you catch them yourself or purchase them from a seafood retailer, many Alabama fish, crustaceans, and mollusks are ideal for outdoor grilling. The following is a basic list of Alabama seafood suitable for the grill. Check with your local seafood retailer to find out what is fresh, seasonal, and suited to your budget.
- Cobia (Ling)
- Mahi-Mahi (dolphinfish)
- Porgy (Sea Bream)
- Rainbow trout
- Redfish (Red Drum)
- Snapper (numerous species)
- Spanish mackerel
- Striped bass
- Aquacultured oysters
- Softshell crabs
- Freshwater prawns
- Shrimp (pink, white, brown, royal red)
How much seafood to buy depends on the number of people you are feeding and whether the seafood will be in a sauce or mixed with other ingredients. The following is an estimate of the amount of seafood to buy.
Fish Per Person
For whole fish, consider 3⁄4 to 1 pound (12 to 16 ounces) per person. Dressed fish that is ready to cook, meaning headed, gutted, scaled, and fins removed, will take 6 to 8 ounces. Fillets are practically boneless sections of flesh cut from either side of the backbone. Steaks are crosswise cuts of fish that include a small portion of the backbone. For either fillets or steaks, you need 4 to 6 ounces per person.
Mollusks (Oysters) Per Person
- In the shell: oysters, 1⁄2 to 1 dozen depending on size
- Shucked: oysters, 1⁄2 to 1⁄3 pound
Crustaceans Per Person
- Whole: 1 dozen
- Headed: unpeeled, 1⁄2 pound
- Headed: peeled, 1⁄3 pound
- Live meat:1 to 11⁄2 pounds
Freshness and Quality Attributes
Fresh seafood should not smell fishy, sour, or ammonia-like. Choose seafood that has a faint sea odor. Freshly cut fish, peeled crustacean meats, and shucked mollusks should be moist, never slimy or dry around the edges.
Fresh, high-quality fish have clear, well-rounded eyes. Older fish may have eyes that are clouded, dry, and sunken in. The gills of fresh fish are bright red or pink, not darkened or slimy. The flesh of fish should be moist and springy to the touch, not mushy.
Crustaceans also have several easily noticed qualityrecognition points. The tail meat from prawns and shrimp should be uniformly light-colored with no signs of discoloration around the tail joints. Reject crustacean tail meat that is slimy or smelly. Likewise, fresh soft-shell crabs should have a mild, pleasant odor. The crab's color should be bright.
Make sure mollusks (oysters) purchased in the shell, are alive. Live molluscs hold their shells closed tightly when handled. If the shells do not close, do not purchase them. In a container, shucked mollusc meat should be plump and covered in its liquor. The liquor should be clear and slightly milky or light gray with no sign of shell pieces or grit. Containers for raw shucked shellfish must bear a legible label that states a "sell by" or "best if used by" or the date shucked for packages holding one-half gallon or more. Check the label before purchase.
Fish, crustaceans, and mollusks are among the most perishable muscle protein commodities. Ideally, seafood should be purchased the day it is going to be used.
Of course, that is not always possible. Take care to adequately and appropriately refrigerate or freeze fish and seafood until it is prepared and cooked.
In general, fresh fish should be used quickly within one to two days of purchase. Wash fresh fish in cold water, pat dry with a paper towel, wrap in plastic wrap, and store in an airtight container in the refrigerator at 32° F to 38° F. Check the air temperature of the refrigerator using a refrigerator thermometer. Fish can be frozen in water and stored in a freezer at 0 degrees F or lower for 4 to 6 months.
Refrigerate live shellfish in a well-ventilated container and cover the container with a damp cloth or paper towel to keep them alive until grilling. Live oysters should be used within 2 days. Scrub live shellfish with a stiff vegetable brush just before grilling. If shells open during storage, tap them. If they close, you can grill them. If not, discard them. After cooking, also discard any that do not open. Frozen mollusks are not good candidates for grilling because the meat is soft and prone to shrinkage.
Live crabs move their legs. Crabs will not be active if they have been refrigerated but should move at least a little. Fresh soft-shell crabs will maintain their quality better when sealed in plastic wrap and packed in ice in the refrigerator. For maximum quality, use within 2 days of purchase. Soft-shell crabs can be frozen and good quality maintained for up to 3 months if they are sealed in several layers of plastic wrap, foil, or moisture-proof paper and stored in a freezer at 0 degrees F or lower. Thaw soft-shell crabs overnight in the refrigerator only.
Store fresh shrimp and shucked shellfish in a refrigerator at 32 degrees F to 38 degrees F in a leak-proof plastic bag or airtight container and consume in 2 to 3 days. Fresh shrimp can be frozen with or without the shell. For best quality, freeze raw shrimp that has been washed with heads removed but shells still on. In a storage container or freezer bag, cover shrimp with cold water, seal, and freeze. The recommended freezer shelf life of shrimp is 3 to 6 months.
- If you are going to cook with charcoal briquettes, line the interior of the barbecue grill with foil for easier cleanup.
- Clean the grill thoroughly.
- Avoid strong lighter fluids or self-lighting briquettes because their odors can overwhelm delicate seafood flavors. Use an electric fire starter or kindling instead.
- A hot fire (375 degrees F to 425 degrees F) is best for cooking seafood. Start briquettes about 30 minutes before you begin cooking. Let the briquettes burn until white-hot, then spread coals in a single layer. Set outdoor gas or electric grills at 425 degrees F and preheat for 15 minutes.
- Oil both the grate and the seafood with vegetable oil or nonstick spray to prevent sticking before placing the grate on the grill.
- Place the grate on the grill and adjust the height 4 to 6 inches above the heat source.
- Cook small, whole, or butterflied fish, fish steaks, fillets, kabobs, crustaceans, and mollusks directly over the heat source.
- Use indirect heat for large whole or stuffed fish. If you are cooking with briquettes, bank hot coals on either side of the barbecue grill and place the fish in the middle of the grill. If you are using an electric or gas outdoor grill, heat the burner on the opposite side.
- For fragile fish, use an oiled, hinged fish basket, a small-mesh seafood grilling screen, or perforated aluminum foil.
- Baste seafood frequently to maintain moistness and prevent sticking.
- Turn most seafoods halfway through cooking time. Fish fillets under 1�

The Formula language is a scripting language used by Lotus Notes. It is often referred to as _USER_ language (pronounced at-formula) because many language elements start with the @-character. Here is an example of a selection formula:
SELECT _USER_ = "NT0050D26"
It was created by Ray Ozzie during the early development of Lotus Notes. He borrowed the compiler and decompiler from the Lotus 1-2-3 spreadsheet, but unlike the spreadsheet language Formula Language was designed primarily for string and list processing, not numerical processing. It was originally a Functional programming language with unique text list-handling features inspired by Ray Ozzie's prior use of Icon and Lisp.
The Formula language has two parts:
- _USER_ for calculations and simple logic
- _USER_ for performing actions in the user interface
_USER_ can be used in several places throughout Lotus Notes. The most important uses are:
- to select documents to show to the user in a view (a kind of index) or to select documents for further processing. In this case, the formula will evaluate to a 'true' (selected) or 'false' value (not selected) for each document.
- to provide default values for fields, to transform the data entered by the user (like stripping off redundant spaces) and to validate this data.
- to get a list of values from a Notes database or even from a relational database (using ODBC). This may be used to provide a user with a list of values to choose from.
- to process a set of documents. The formula is placed in an agent, a program or macro that can be started by a user or by the Notes server according to a schedule. When the agent is triggered, the formula executes for each selected document (this a very limited form of a loop). This is an efficient way of changing lots of documents, if the logic is not too complicated. In case of complicated changes, LotusScript is used.
_USER_ are like menu commands: they perform actions in the Lotus Notes client. Examples of actions are:
- opening a Notes database
- creating an e-mail
- putting the cursor in a specific data-entry field
- closing a window
- starting an agent
_USER_ are primarily used in formulas that are triggered by user action, such as in button formulas. It is possible to combine them with _USER_, for example by making execution of an _USER_ conditional on a field value.

Food industry's green efforts may hit price wall
The European food and drinks industry is finalising plans to measure its environmental performance but increasingly price-aware consumers might derail their efforts, the European Commission cautioned.
A European round table bringing together the food industry, farmers and consumer groups has drawn up a series of 10 guiding principles to assess the environmental impact of food and drink products during their entire life cycle.
The principles, agreed on Tuesday (13 July), will guide the round table's future work on developing a uniform and scientifically reliable methodology for assessing the environmental impact of food and drink products.
It is also meant to serve as a communication tool for companies wanting to boast their green credentials.
The methodology, which is expected to be finalised by 2011, will address key sustainability challenges facing the food value chain, including climate change, resource efficiency, water use and waste reduction.
Mike Faupel from the Sustainability Consortium, an organisation of global companies seeking to improve consumer product sustainability, noted that the proliferation of eco-labels and other green claims led to confusion among consumers.
There is a need for more holistic approach and more transparency in how products are evaluated, he said.
EU principles underline that the environmental information should be provided in an easily understandable way that supports informed choice and allows consumers to compare products.

triple X syndrome
Tuesday 26 February 2008
Definition: Triple X syndrome, also called trisomy X or 47,XXX, is characterized by the presence of one extra X chromosome in each of a female's cells. This condition occurs in about 1 in 1,000 newborn girls. Five to 10 girls with triple X syndrome are born in the United States each day.
Most often, this chromosomal change causes no unusual physical features or medical problems. Females with triple X syndrome are sometimes taller than average and have an increased risk of learning disabilities and delayed speech and language skills.
Developmental delays and behavioral problems are also possible, but these characteristics vary widely among affected girls and women.
Most females with triple X syndrome have normal sexual development and are able to conceive children.


Since the beginning of the global emergency, airports in the country developed a preventive protocol to continuously evaluate risks and mitigate the potential spread of COVID-19, including sanitary inspections of aircrafts and the use of technology to identify passengers with a fever, among others.
In this video, AERODOM, holding company for Las Americas Airport in Santo Domingo, illustrates some of the prevention & control methods that are in place, including the use of masks, new sanitation technologies and rearrangement of wait lines to maintain a safe distance between passengers.


Adding Push Notification
The Thing-IF SDK uses the push notification for receiving the response from the things. For iOS, Kii Cloud provides the push notification via Apple Push Notification service (APNs). You need to make some APNs-related configuration and prepare your build environment besides configuring Kii Cloud.
See Overview of the Push Technology for iOS for the technical overview of APNs.
Initialization of push notification is not required if your mobile app does not manage end nodes but only the gateway which interacts with Thing Interaction Framework.
By following the description in this page, you will be ready to receive push notifications from Kii Cloud.
Setting up
You need to complete various configurations in order to enable push notification with APNs. Kii recommends you to follow the instructions in the tutorial because such configurations and implementations of push notification are complicated.
First, in order to make push notification functional, follow the steps described in iOS Push Notification Tutorial to set up, implement, and test push notification. Skip the steps that you have already done such as integration of the Kii Cloud SDK into your development project. Choose Swift 2.3 in the tutorial because the Thing-IF SDK supports Swift 2.3 only.
After completing the above steps, go to Modification for Thing-IF.
The tutorial explains how to enable the feature in the development environment. You need to enable it in the production environment in a similar way before you release your mobile app. Also, note that the tutorial does not cover the instruction for integrating the Thing-IF SDK. You need to integrate the Thing-IF SDK to your project for the Thing-IF SDK features.
Modification for Thing-IF
Once you are done with the tutorial, we will remove lines that are unnecessary for mobile apps with the Thing-IF SDK. Replace the lines for device installation that use the Kii Cloud SDK API with those that use the Thing-IF SDK API. This is because the method for device installation is different between the two SDKs.
Remove the call of the KiiPushInstallation.installWithDeviceToken method from the application:didRegisterForRemoteNotificationsWithDeviceToken: method in the AppDelegate class. The code below reflects the removal.
 let username = "user1"
 let password = "123ABC"
 KiiUser.authenticate(username, withPassword: password) { (user: KiiUser?, error: NSError?) -> Void in
 if (error!= nil) {
 print("Failed to authenticate: \(error!.userInfo["description"])")
Leave the sample code as the above for now. We will insert the API call for Thing-IF later. See Installing a device in the Initializing and Onboarding topic for more information.
Also, according to the specification of your mobile app, rewrite the login processing that uses user1 for testing. The sample code in the Initializing and Onboarding topic uses a pseudo user as a thing owner. If you implement a login screen where an explicit owner user logs in, move the above login processing to the processing class of the login screen. Also, update the program structure so that you can use deviceToken that contains the device token from APNs after the owner logs in.
Customizing a push notification
Some of the APIs used in the initialization of push notification are iOS APIs. They do not depend on Kii Cloud.
You can also customize the way that push notification works by using the APNs features such as categories. For implementation, see Initializing APNs in the push notification topic for the Kii Cloud SDK.

Once you have identified that you are in an emotional affair or you have been caught in an emotional affair, there is a specific reconstruction process to follow to heal your relationship.
These are the first 5 things to do once the initial disclosure has come out:
1. Seek IMMEDIATE help from a profession. The longer you wait the harder the healing process is. Don't expect that you and your partner can navigate your own way through this. You are too emotionally involved to stay focused.
2. The person you had the emotional affair with needs to be gone. Completely cutoff contact.
3.Both of you must make a commitment to the long road of healing for it to work.
4.Full disclosure of things such as who it was with, what happened, when, how long, where, and that it ended are important. No new details can come up after this point. Otherwise you will start back from square one.
5. Look at the causes that lead up to the affair.
Once these first steps are taken then you can start the road to recovery. These steps all happen simultaneously, and must continue over a significant period of time to be effective.
1. Rebuild safety in the relationship
2. Rebuild trust
3.Begin the forgiveness process
4. Manage triggers as they arise
This is a difficult yet powerful process to go though. Remember relationships can heal after and affairthere is HOPE!

1. After installing the 3DEnvironment using the Macromedia Extension Manager, open Flash and start a new file.
Press Ctrl+F7 (Win) or Cmnd+F7 (Mac) to open the Component panel and drag a copy of the component onto the stage.
2. Next you must create a symbol to exist in the 3D environment you're creating. Press Ctrl+F8 (Win) or Cmnd+F8 (Mac) to open the 'Create New Symbol' dialogue box. Enter a name for the symbol, for the purposes of the tutorial name it circle_clip. Ensure that the type is set to 'Movie clip'. Tick the 'Export for Actionscript' checkbox (the 'Export in first frame' check box will be ticked automatically.) Enter an 'Identifier' for the clip, for the purposes of the tutorial give it the instance name circle. Click OK.
3. On the timeline of the clip you have just created draw a graphic, for the purposes of this tutorial draw a circle.
4. Return to the main timeline, select the 3DEnvironment component on the stage and press Alt+F7 to open the Component Inspector panel.
5. Press the Add button to add an object to the 3D environment. The new object panel will appear once you press the Add button.
Enter x, y and z positions for the object in the 3D environment. The x value indicates the desired horizontal position, the y indicates the desired vertical position and the z value indicates the desired depth.
Enter the regName for the object. This value allows you to refer to the object later. Note that the regName should be a unique name.
Finally enter the linkage Identifier of the symbol you created in step 2.
Now that the object has been added to the object's list, you can edit the object's position, regName and linkage identifier if you wish.
6. The essence of a 3D environment is the position of objects relative to each other. To create a three dimensional effect with your component repeat step 5 several times to create more objects. (For the purpose of the tutorial you can use the same linkage identifier so that you do not need to create multiple symbols.)
7. In the Component Inspector, press the Control tab. Tick each of the checkboxes to include that type of movement.
Select the text field labelled Forward and press the up arrow button on your keyboard.
Select the text field labelled Backward and press the down arrow button on your keyboard.

When you test your file, pressing and holding these buttons will control the movement of your environment. For more information on the subject please refer to the Using the Control tab section of this userguide.
8. Press Ctrl+S (Win) or Cmnd+S (Mac) to save your file and Ctrl+Enter (Win) or Cmnd+Enter (Mac) to test your file.
Press and hold the keys that you entered in step 7 to move your environment.


Heart of Palm
To identify a list of farms or exporting companies that specialize in exporting freshly peeled hearts of palm to the US by air. The list will only include primary growers or exporters of the produce from host countries.
Early Findings
 - Heart of palm is also commonly known as "palmetto," a local name for the product.
 - The world's largest producer of palmetto is DEMASA, which controls 20 percent of the world's production. However, DAMASA only offers the canned variant of the product and does not export freshly cut produce to the US.
 - Other top producers of palmetto include Conservas del Valle, Palmitos of Costa Rica, Ticochaal, Palmitos del Norte, Palmitos Amador, Corpa S.A., Tucurrique, and El Hogar.
 - Due to their extremely short life span, fresh palmettos are mostly sold in the local food markets of their host countries, while those meant for export are often canned.
Summary of Findings
In our initial hour of research, we were able to identify the top producing countries and top producers of the "heart of palm" across the globe. Although we were not able to identify any farms or exporters outside the US that facilitate the delivery of fresh palmettos to the US, we believe it is possible to identify a number of businesses that provide the required services based on the insights already garnered in the preliminary research.

 1. For a mapping between two Euclidean spaces, is it a linear conformal mapping if and only if it is a similarity transformation?
 My answer is yes, because the Jacobian matrix of a conformal transformation is everywhere a scalar times a rotation matrix.
 Note that both allow reflection, i.e. change of orientation.
 2. Is it correct that a conformal mapping may not be an affine nor projective transformation, because it may not be linear?
Thanks and regards!

1 Answer 1
 1. Yes, for elementary reasons. Let $f$ be a linear conformal map and apply this to any triangle $ABC$. Then $f(AB),f(BC),f(CA)$ will be lines by linearity, and by conformality $f(ABC)$ will have the angles of $ABC$ so they will be similar therefore $f$ is a similarity mapping.
 2. Yes, consider inversion with respect to a fixed circle.

(Note: It might help if you explain why you want this. There might be a better way to approach the underlying problem.)
Is this possible?
Not with ForeignKey alone, because you're overloading the column values with two different meanings, without a reliable way of distinguishing them. (For example, what would happen if a new entry in the target table is created with a primary key matching old entries in the referencing table? What would happen to these old referencing entries when the new target entry is deleted?)
The usual ad hoc solution to this problem is to define a "type" or "tag" column alongside the foreign key, to distinguish the different meanings (but see below).
Is this what Generic relations are for?
GenericForeignKey is just a Django convenience helper for the pattern above; it pairs a foreign key with a type tag that identifies which table/model it refers to (using the model's associated ContentType; see contenttypes)
other_type = models.ForeignKey('contenttypes.ContentType', null=True)
other_id = models.PositiveIntegerField()
# Optional accessor, not a stored column
other = generic.GenericForeignKey('other_type', 'other_id')
This will allow you use
other like a ForeignKey, to refer to instances of your other model. (In the background, GenericForeignKey gets and sets
other_id for you.)
To represent a number that isn't a reference, you would set
other_type to None, and just use
other_id directly. In this case, trying to access
other will always return None, instead of raising
DoesNotExist (or returning an unintended object, due to id collision).
