An Empirical Investigation into the Relationship Between Computer Self-Efficacy, Anxiety, Experience, Support and UsageJournal of Computer Information Systems
AbstractOrganizations make significant investments in information technology. However, if individuals do not use information system applications as anticipated, successful implementation can be hard to achieve. In order to investigate some key factors thought to affect an individual's use of information technology, this study draws on Bandura's Social Cognitive Theory (SCT), Triandis's Theory of Interpersonal Behavior (TIB), and the computer anxiety literature to develop its conceptual model and research hypotheses. An empirical investigation (n=978) found support for the majority of the hypotheses. As suggested by SCT, experience and support were positively related to computer self-efficacy, and computer self-efficacy was negatively related to anxiety and positively related to usage. As suggested by TIB, experience was positively related to usage. Furthermore, computer anxiety was negatively related to experience. By providing insight into these important relationships, this research can help further understanding of their role in the acceptance and use of information technology.

A Discourse Analysis of Chinese Disagreement Management Strategies in Business Negotiation Settings [electronic resource]
Abstract (Summary)This dissertation investigates strategies of native Mandarin Chinese speakers in disagreement management at business negotiation settings by examining linguistic and non-linguistic resources recurrently utilized by the participants in this study. A principal concern is how cultural and contextual factors contribute to the formation and interpretation of the strategies.The present study is intended to provide Western audiences with practical information about Chinese tactics in their disagreement management particularly at business settings. The ultimate goal of this study is to enhance intercultural communication and understanding. Under the guidance of the theoretical and methodological principles of interactional sociolinguistic approaches, I observed and filmed seven live Chinese business negotiation meetings and conducted three post-interviews with key participants at three Chinese cities. The treatment of the data includes transcribing the set of the data, identifying the instances containing the strategies, and analyzing patterned strategies with the qualitative method. In this study, I argue that the preference for agreement is situational specific. The findings indicate Chinese people are conscious of their opponent's face, but business interest outweighs face politeness. The study shows that business interest and power/personal relationships are major factors in the participant's choice of disagreement management strategies.

The Cronulla Wastewater Treatment Plant (WWTP) is one of 30 wastewater treatment and water recycling plants in greater Sydney, the Blue Mountains, and the Illawarra. It is owned and operated by Sydney Water, Australia's largest water utility. The plant is located on the southern end of the Kurnell Peninsula (about 18 km [11 miles] from the city center), and treats about 54 million liters (14 million gallons) of wastewater a day.
Like many of Sydney Water's WWTPs, the Cronulla WWTP is located in a sensitive environmental area. Concerns regarding the potential impact of odors on a new residential development near the WWTP led to a review of odor sources and environmental factors. The source of odor was determined to be coming especially from the primary treatment areas: inlet screening, grit tanks, primary sedimentation tanks (PSTs), PST launders, inter-stage overflow, and pumping station areas. There were existing covers on the grit tanks, launders and the inter-stage overflow area, but the covers had reached the end of their service life and were not effectively controlling odor emissions.
Sydney Water felt it had an obligation to be a responsible neighbor, so it decided to develop and implement an odor control improvement project that would drastically reduce predicted odor impacts. The project would also ensure the Cronulla WWTP could continue to perform in line with environmental requirements. The Odor Management Program Alliance (Sydney Water, Lend Lease, and CH2M Hill) worked to design, deliver, and manage the project, which included three areas of focus related to odors:
- Covering the various treatment tanks to capture foul air while allowing the required operator and maintenance teams access to tank internals.
- Rehabilitating and protecting concrete structures below the covered areas to ensure the intended asset life.
- Constructing a new odor treatment facility to capture and treat the foul air.
Because the Cronulla WWTP had been identified as having a 'high odor risk', the design and implementation of the odor control technology was important. "Odor control covers must be tailored to suit the requirements of plant operational and maintenance teams," says Robert Aurisch, Cronulla Plant Manager. A combination of innovative and traditional cover solutions were needed to address the odor issue.
Sydney Water and their engineering advisor, CH2M Hill, researched available cover technologies to determine the appropriate cover designs for the different process units at the Cronulla WWTP. When it came to choosing a cover technology for the PSTs, launders, and portions of the inter-stage overflow area, operational and maintenance teams at the Cronulla WWTP knew that access and egress would be critical factors. For example, when PSTs are taken out of service for cleaning, the scraper flights must be lifted slightly to allow wash water and residuals to drain. Any odor control cover must allow this access. Considerations also included safety, manual handling requirements, confined spaces, air tightness, maintainability, and cost. Retractable covers from Evoqua's Geomembrane Technologies™ brand were selected for these large areas of the plant, where access and egress were critical.
The retractable covers were chosen because they effectively capture foul air while still allowing workers quick and easy access to tank internals. The cover system consists of retractable fabric covers tensioned over supporting aluminium arches. The design includes inspection hatches as well as clear span guardrails that allow covers to be safely opened and closed without interference from standard guardrail supports.
Sydney Water and its Alliance partners developed and implemented the right solution for the Cronulla WWTP to help it fulfill its obligations as a neighbour within its community.
Wastewater is treated to tertiary standard (the highest level of treatment) and then used for irrigation. Odors are proactively controlled, while protecting plant infrastructure and allowing operational and maintenance teams to perform their necessary work.
With the newly designed ventilation system, Evoqua's Geomembrane Technologies™ brand covers are able to maintain a negative pressure of around 20 Pascal (0.08" w.g.), which means an odor capture of more than 99%.

Trapezoid Midsegment Investigation
How do you know the quadrilateral initially constructed is a trapezoid? (What postulate or theorem helps justify this?)
The thick black segment (with three tick marks) is called a median (or midsegment) of a trapezoid. Define the term median of a trapezoid without looking up its definition on another site.
What two facts/properties about the median of a trapezoid does this applet illustrate?
Suppose the bases of the trapezoid above measured 14 inches and 26 inches. What would the length of its median be?
Suppose a trapezoid has a median with length 35 inches and one base measuring 23 inches. What would the length of its other base be?
Now move any point so that one of the trapezoid's bases has length = 0. Then re-slide the slider. What other theorem(s) previously learned does this applet now show?

Study objectives: Conditions that give rise to reduced lung function are frequently associated with low-grade systemic inflammation, which may lead to poor cardiovascular outcomes. We sought to determine the relationship between reduced FEV1 and cardiovascular mortality, independent of smoking.
Design: Longitudinal population-based study and a meta-analysis of literature.
Setting: Representative sample of the general population.
Participants: Participants of the first National Health and Nutrition Examination Survey Epidemiologic Follow-up Study who were 40 to 60 years of age at baseline assessment (n = 1,861).
Measurements and results: We compared the risk of cardiovascular mortality across quintiles of FEV1. Individuals in the lowest FEV1 quintile had the highest risk of cardiovascular mortality (relative risk [RR], 3.36; 95% confidence interval [CI], 1.54 to 7.34). Compared to FEV1 quintile 1, individuals in quintile 5 had a fivefold increase in the risk of death from ischemic heart disease (RR, 5.65; 95% CI, 2.26 to 14.13). We also performed a systematic review of large cohort studies (> 500 participants) that reported on the relationship between FEV1 and cardiovascular mortality (12 studies; n = 83,880 participants). Compared to participants in the highest FEV1 category, those with reduced FEV1 had a higher risk of cardiovascular mortality (pooled RR, 1.77; 95% CI, 1.56 to 1.97).
Conclusions: There is strong epidemiologic evidence to indicate that reduced FEV1 is a marker for cardiovascular mortality independent of age, gender, and smoking history.

Happy June from the Department of Distance Learning. As the first mini session is progressing, there have been some questions about weighting grades in Blackboard. Since most of you weight by category, there is a three step process:
- Set up categories (and remove duplicates).
Manage > Categories
- Set up category weights in your weighted grade column.
Weighted Column > Edit Column Information
- Assign a category to all items that will be graded.
Manage > Column Organization
In addition to the steps above, here are a few items that frequently cause problems:
- Items must be "included in Grade Center calculations" in the item settings.
- An item must include "possible points" to affect the calculation.
- When selecting "Yes" for Calculate as Running total, make sure to assign a Zero for items not attempted or students will not be penalized for not attempting the assignment (excused absence).
The following short video might be helpful in setting up Grade Weighting (start at 1:35 if you weight by category, rather than by individual items). Weighting Grades in Blackboard 9.1 (4:53)
Please see the following document for a list of known issues in Blackboard and solutions or work arounds:


The county seat in Norfolk, the city of Norwich has the most American connections in the county.
In the early seventeenth century, a number of ministers and parishes relocated from the city due to religious conflicts with the Bishop of Norwich. Also under pressure were the Dutch migrants in the city who were seen as 'strangers' to the English. Peter Folger, one of these early strangers who left for America was the ancestor of Benjamin Franklin. The religious influences in the city led to a strong anti-slavery, and abolitionist movement in the late eighteenth-century, the chapter formed in 1787 was one of the first in the nation.
In the twentieth century a large number of US Air Force servicemen and women were based in Norfolk, and frequented the night spots of Norwich when they were able to get time off their bases.
In recent times Norwich been visited by a number of famous Americans including Barnum and Bailey's Circus, Laurel and Hardy, Cary Grant, Glenn Miller, James Stewart, Jimi Hendrix, Geno Washington and the Ram Jam Band, and Muhammad Ali.
Other famous people with a connection to Norwich and North America are Francis Lawes, Michael Metcalf, Thomas Allen, the Pettus family, Ukawsaw Gronniosaw, Olaudah Equiano, Harriet Martineau and Vernon Castle.

Lempa RiverArticle Free Pass
Lempa River, Spanish Río Lempa, river in Central America. It rises in Guatemala near Esquipulas, crosses a corner of Honduras, and enters El Salvador at Citalá. After cutting across El Salvador's northern mountain range, it flows eastward for over 80 miles (130 km) and then southward for 65 miles (105 km) across the southern mountain range to enter the Pacific Ocean after a total course of about 200 miles (320 km). It is El Salvador's largest and only navigable one. Its northern valley has hydroelectric projects that supply power to much of El Salvador. Its southern basin has been developed agriculturally, sisal (a cordage fibre) being the major crop.

The first potlid with a colored transfer print was made in 1846 and was called Polar Bears. The English Staffordshire potteries made ceramic containers with decorative lids for bear's grease, shrimp or meat paste, cold cream, and toothpaste. Printed advertising and pictures of historical events, portraits of famous people, or scenic views were designed in black and white or color. Reproductions have been made.

Welcome to the Social Justice Neuroscience and Psychology Laboratory at the University of Chicago. The aim of our research is to understand how to decrease discrimination. Specifically, our research explores how social categories such as race, gender, and sexual orientation influence prejudice, stereotyping, and discrimination. Broadly, we are interested in how perception, emotion, cognition, and motivation shape intergroup relations and social justice. The ultimate goal of our work is to use empirical evidence to inform policy by identifying and characterizing robust and reliable interventions for prejudice and discrimination, and testing the constraints of these interventions in producing lasting reductions in inequality.
Our lab explores social psychological theory by integrating across the social and neural sciences. We utilize innovative neuroscience and behavioral research methods and quantify when and why intervention is successful. We use a range of techniques, employing a multi-level approach from hormonal determinants (e.g. cortisol), to neural activations (e.g. EEG, fMRI), to behavioral outcomes, with the ultimate goal of understanding social change in real-world situations, such as in economic and judicial contexts. Such an approach will provide insight into the origins of discrimination, how specific interventions operate, and under what circumstances these techniques are practical and predicative of bias reduction.

Naming the 'harshest sound in the world' seems like it would be a subjective matter, but scientists say they have pinpointed the sound that qualifies for the moniker.
Perhaps for you it is nails on a chalkboard, or maybe the snap of bubblegum, or even the sound of a particular person's voice.
Naming the "harshest sound in the world" seems like it would be a subjective matter, but scientists say they have pinpointed the sound that qualifies for the moniker.
According to a research study by a team at the University of Newcastle, the harshest sound in the world is a knife against glass.
The team examined brain activity in a group of volunteers, who listened to 74 recorded sounds under an MRI machine and ranked each experience, according to ABC News. The 13 subjects found the sound of a fork against glass to be the second worst sound.
The group found that sounds with frequencies of 2000-5000 Hz were the most disagreeable.
The MRI scans showed that these sounds increased blood flow in the brain's auditory cortex, which processes sounds, as well as triggers the amygdala, a primitive part of the brain that processes our emotional responses, according to MSN.
While it's hard to imagine a study like this ever having a purpose beyond finding a better torture technique, Tim Griffiths, the study's co-author, said, "The new finding in this study is to precisely define the loop between the auditory cortex and the amygdala."
In the mood for a bit of masochism? Take a listen to what scientists say is the harshest sound on Earth.

There's a hole in the middle of Prague, and we want you to know what's in it. The early 1980s metro station at Národní třída is the scene of a fascinating archaeological dig that we'll be visiting in this month's Science Journal.
The Národní třída metro station that most of us know was a metaphorical hole even before the dig – a line of fast food kiosks between two chrome and plastic socialist structures that was a favourite stomping ground for beggars and winos. Plans to develop the plaza for office and shopping space has peeled back the grimy surface of this historic part of Prague to reveal century after century of history in strata that can be read like a book back to the 1100s. Here to do that for me is Polish archaeologist Tomasz Cymbalak, who is heading the dig.
"What we see in front of us are the remains of the townhouses that used to be here. There are five of them here, and the way they looked changed from small houses of townspeople to larger buildings that were built further back from the street. Through time, the structure gets more dense, they added wells and waste pits, and those are the places where we make the most finds. And aside from those coins, pottery fragments, bones and so on, we have taken various samples for archeo-botanic analyses, so we will be able to reconstruct the early Praguers' diet, the illnesses they suffered from, and so on."
So from where we're stranding now – about four or five metres above the bottom of the dig – we can see a very compact kind of maze of stone walls from which you can kind of see what a busy place this city was even that long ago...
"Yes, it shows the very lively development of this part of the city. The place where we are standing is actually the border between Old Town and New Town. Right next to the place we are studying was an ancient road that led from Prague Castle through Old Town to Vyšehrad, and one of the gates to the city through the fortification was a few dozen metres from here. So this was a gathering point for traders and other service tradesmen. In the later periods, like in the 17th and 18th century, then of course the social structure of the inhabitants changed and Renaissance buildings are built, followed by Baroque and Neoclassical and so on."
Archaeologists did of course know there would be findings here – aside from the evidence from the sonar scans that preceded the dig, you will always find layers of pottery, bones and other relics wherever you dig down into city centre Prague. But they were nonetheless greatly surprised by the excellent way everything under Národní Třída had been preserved, even despite the encroachment of the metro in the 1980s, and the dates that the evidence went back to. While they expected 14th century remnants from the establishment of New Town by Charles IV, they found even the predecessors of those structures – not the wooden and mud buildings themselves per say, but the outlines of them left like photonegatives left in the ground. Another surprise was a burial site lying just under what is now Tesco.
"What you see here is part of a burial site where the individual bodies have been laid in ordered rows like on a chessboard. We have already dug out the graves here. The bodies were laying with their heads to the west, feet to the east, with their arms by their sides, and the state they were in was surprising, because they were wonderfully preserved. So all in all we uncovered six graves that I would tentatively date to the turn of the 13th century."
"We know that among them there were about three women – the anthropological survey is still underway. The bones show that the deceased worked in a hunched over position, they did hard work that left its mark on their skeletons. We are also going to do a DNA analysis as well and from that we should have some approximate idea as to their ethnicity or where they were from."
Can you describe what it might have looked like right here at Národní Třída at the time that these graves were dug, in the 12th to 13th centuries?
"The structures were primarily wooden, with a couple stone buildings and were compacted together. The road network was much smaller than it is today, there were less streets, but the road that we are on just now existed even in the early Middle Ages, and that's Spalená Street. The water situation was different, there must have been several creeks here, and we know that the terrain was much more rolling, with small hills and sunken farm paths. There was of course much more greenery – bushes and trees. There were groups of houses – like countryside cottages – one next to the other, making small units. What was in this area was a small settlement that provided material support for the Old Town."
Under what is going to be a very modern multifunctional building at this site you can follow the complex meshing of one era into another. As the farmers ran out of space for storing their products and feeding their animals, the space became used more and more by merchants and craftsmen, until even more people begin moving to the city in the 19th century and there is more residential rather than economic area. In the 20th century the lot changes altogether, filling up with restaurants, offices, administrative spaces and so on, showing the various needs of each century until it is cemented over for the construction of the Soviet-style metro station. The metro in fact runs just metres away from ancient cellars still being explored and learned from beneath Spalená Street.
"Four or five."
Four or five metres, and it's very cool now, and it's very beautiful.
"This is the oldest of the cellars that we have here, so it's from the mid 1300s. The layout of this cellar is beautifully legible and it's a wonderful teaching aid for students and art historians. You can follow the development of building methods and urban transformation on the structure here. The walls show right here that the original floor was almost two metres higher, and the ceiling was not vaulted but flat. As they ran out of space they made these other cellars under the street; this one is twice as large, and they stop changing things for the most part at the beginning of the 16th century. And next door there are another two cellars, each about three times larger than this one...
"What we see here is a wartime passage hole. During WWII, when they found there were too few air raid shelters, the protectorate government ordered that the gothic cellars be used, because they were of such massive design, and they made these passageways between them so that if one began to collapse people could run to another. It's wonderful, you have a real example here of how people lived and how things worked."
Coming back up to the busy streets above is something of a shock, and it is a beautiful reminder of everything the modern world is literally based on and derives from. As one shopping centre and multifunctional building springs up in Prague after another, I'm concerned about whether these ruins will go the way of so many others, being documented only to be preserved in archives while progress ploughs over the real thing forever. The answer is happily no.
"It looks like most of the 11 cellars on this site will remain and will be written on to the list of cultural monuments. The intention for the future is that it be made accessible to the public in what could be a protected archaeological zone. Maybe in the end it will be preserved partly for archaeological and teaching purposes, or there could be a kind of gallery where the original structures that are in very good condition can remain and will not be damaged."
That was archaeologist Tomasz Cymbalak ending that edition of Science Journal. Thanks for joining us today and I hope you'll tune in again next month.
The episode featured today was first broadcast on August 29, 2010.


Jernkilden i Sæby (The Iron source)
Jernkilden (The iron source) in Sæby played such a big role for a period that Sæby at that time was one of the leading spa towns. One thought that ferrous water was good against many different ailments.
The source has been known for centuries, but the Sæby Iron Source building, in Art Nouveau style drawn by Ulrik Plesner, was not bulit before the year 1887. The source building, which gathered around the well itself, was open towards Sæbygård Forest, while the slope and the forest sheltered from the west wind.
For many years, the iron source has lived a sad life. It was allowed to decay and was repeatedly subjected to vandalism. But now the beautiful building has got the great renovation and has thus again become an attraction for Sæby.


Do Drywall Screws Rust?
Screws are screws right? Believe it or not there are many different types of screws that are used for certain projects or situations. This means that they are made from different materials and configured differently in order to get their specific job they are designed for done in their own special way.
In this article we will be specifically talking about the drywall screw. Just like the name gives away it is typically used to hangup sheets of dry wall to wall studs or ceiling joists.. I know, mind blowing stuff right? So one question we may ask ourselves related to drywall screw is… do drywall screws rust? Even though the black phosphate outer coating will help prevent rusting of a drywall screw, these screws will eventually rust. Since after awhile drywall screws will rust, they are typically only used for indoor projects. If used outdoors it can cause them to rust since they would be exposed to the elements.
If you want to find the best Drywall Screws, click here.
What is a Drywall Screw?
A drywall screw are the standard screw used to secure sheets of drywall. Many people will also use drywall screws for other projects because they are inexpensive and the heads on these screws are flat, meaning they will keep from sinking into the wood. This means there is less of a chance of splitting the wood. You need to be careful using a drywall screw for non drywall projects because they are very brittle and can snap easily.
What Causes Rust?
Rust is a natural process where the iron in metals comes into contact with oxygen and water. This then causes it to corrode and deteriorate. Since oxygen and iron have opposite charges they are attracted to each other. So when they combine it causes oxidation and the reaction then creates rust.
Rusting causes issues because it looks gross and makes the metals become weak by causing decaying. This causes major problems because you expect metal to be a strong and durable metal but if rust is occurring that once strong object could become weak and nimble and cause serious problems with the functionality.
What To Do If Your Screw Rusts
If you have a screw that is deeply rusted it is important to fix this asap. If left you never know when it will snap and whatever it was holding up could crash and fall. The first thing we want to do is remove the rusted nail.
Steps to remove a rusted screw:
 1. Apply a product such as WD-40 that will help dissolve the corrosion on and around the screw. Things such as hydrogen peroxide, lemon juice, or cola can also be used.
 2. Gently tap the head of the screw with a hammer. This will cause vibrations which will allow the solution to work its way through the threads of the screw.
 3. Try to unscrew to remove the screw. If it's still stuck then try again.
 4. Clean the area where the screw was.
 5. Replace with a new screw.
Always keep an eye out for rusted screws in the home. It is vital to always replace them if they are found. We do not want to wait until it is too far gone.
The Make of a Drywall Screw
Drywall screws are inexpensive and can be bought in huge tubs because for any drywall project you are going to need a plethora of screws to get the job done. So what makes a drywall screw different than other types of screws?
The drywall screw is a threaded screw from the head to the bottom. It is coated in zinc or phosphate. The phosphate coating, which gives it its black color, is what makes it more rust resistant. This doesn't mean its rust proof though and is still not recommended for using on any outdoor projects.
Sizes Drywall Screws
Drywall screws come in many different sizes. They can range from 1-8 inches long because building materials range in thickness. Materials would range from metal sheets to wood beams.
Today's typical home will consist of 1/2 inch thick drywall, but the thickness can range from home to home. It is important to know the thickness of the drywall so you can choose the right size of drywall screw to get the job done.
 - 1/4 inch drywall: Use 1 inch to 1 1/4 inch drywall screws
 - 1/2 inch drywall: Use 1 1/4 inch or 1 5/8 inch drywall screws
 - 5/8 inch drywall: Use 1 5/8 inch or 2 inch drywall screws
Thread Types: Coarse or Fine
Drywall screws can have one of two thread types. Each are used for a very specific reason and need to be considered before buying the right one. It is important to know what your studs are made of before picking the right thread type for your drywall screws.
 1. Coarse: Used for drywall and wood projects. Have wide threads in order to grip to the wood and pull the drywall against the studs as close as possible.
 2. Fine: Used for installing drywall into metal studs. These drywall screws work great with metal because they are self threading.
Now we know if your studs are made of wood, use coarse, if made of metal, lets go with the fine thread.
Drywall Screws vs. Wood Screws
Obviously the number one use for drywall screws is to be used for putting up sheets of drywall in the home. They can either be attached by screwing into wood or metal studs.
Some DIYers use drywall screws for building projects, which I would not recommend. Drywall screws are brittle and do not bend easily, which means at any moment they could snap, especially if used in hardwood. If they snap then it leaves the shaft in the wood with the head gone… pretty hard to remove a screw with no head. Drywall screws are hardened so Phillips slots wont strip out under high stress from power tools. Wood screws are thicker and made of a softer metal making them more snap resistant. Lets make sure we use wood screws over drywall screws when we are doing any wood working.
Wood and drywall screws also have different thread patterns. Wood screws are smooth right under the head and not threaded. This part ensures the top part of the screw slides in the wood makes it easier for the lower part of the screws threads to clamp on the wood.
Drywall screws are threaded all the way to the head. Which means when two pieces are attached together sometimes it could keep them apart unless the two pieces are clamped together in the beginning.
Final Thoughts
Dry wall screws are made for a very specific job. To hang up sheets of drywall. This means if used for this specific job you probably do not have to worry about them rusting. However, if you choose to use this screw for it not intended purpose or outside, it is highly likely the phosphate covering will deteriorate over time and the drywall screws will indeed rust.
Related Questions
What type of screws are rust resistant? Any stainless steel screw are the most rust resistant.
Will zinc screws rust? Zinc screws will rust. They are corrosion resistant but will rust if the coating deteriorates or exposed to a wet environment.
Can I use drywall screw outdoors? You should not use drywall screws outdoors. The elements of the outdoors will deteriorate the phosphate coating and cause the screw to rust quickly.

We consider the problem of multiple lightweight devices monitoring unstructured data on the web. To do this effectively, we propose a 3-tiered architecture for a consolidated system that monitors changes in unstructured web data to cater to these clients (lightweight devices).
Typically, our clients work under constrained resources like memory, network bandwidth, processing power, etc.
This limits their ability to run applications that require timely and relevant web-data applications like news readers, offline/online search engines, directories, or general web-page monitoring tools.
The proposed system can deliver relevant and timely data to its clients by adapting to their profiles and usage statistics, which it uses to crawl and monitor the web effectively.
Existing literature covers numerical and textual updates in either the monitoring or the crawling context. However, there is little or no existing work on optimizing overall monitoring that includes both textual content as well as client side constraints. We formalize this overall optimization problem to some extent, and propose modules in each layer of our architecture that work together to minimize our objective.
This objective includes user satisfaction and resource costs. Our layered architecture includes modules to manage novelty detection, workload, monitoring and scheduling, client profiles, client usage statistics, data packaging and delivery, client connections, etc. We also propose ways to evaluate our architecture across a few variations in managing some of these modules like crawling, client connections, and delivered data size.

SEED: Social Economic Environmental Design® provides a common standard to guide, evaluate and measure the social, economic and environmental impact of design projects.
SEED maintains the belief that design can play a vital role in the most critical issues that face communities and individuals, in crisis and in every day challenges. To accomplish this, the SEED® process guides professionals to work alongside locals who know their community and its needs. This practice of "trusting the local" is increasingly recognized as a highly effective way to sustain the health and longevity of a place or a community as it develops.
The name "SEED" was first proposed during a 2005 meeting at the Harvard Graduate School of Design where architects, designers, and other diverse experts in the public interest design movement convened to evaluate how design could respond to the triple bottom line of social, economic, and environmental justice.
SEED's Mission is to advance the right of every person to live in a socially, economically and environmentally healthy community.
- The SEED guiding principles are:
- SEED Principle 1: Advocate with those who have a limited voice in public life.
- SEED Principle 2: Build structures for inclusion that engage stakeholders and allow communities to make decisions.
- SEED Principle 3: Promote social equality through discourse that reflects a range of values and social identities.
- SEED Principle 4: Generate ideas that grow from place and build local capacity.
- SEED Principle 5: Design to help conserve resources and minimize waste.


How To Read a Load Chart
Each crane has a load chart that, in short, specifies the crane's capabilities — detailing its features and how its lift capacity varies when considering distance and angle. Just like the old saying if you fail to plan, you plan to fail,' failing to consult a crane load chart before renting or employing a crane for a specific job could leave you with too much or too little capacity for your job.
Before a crane is rented, transported, employed or purchased, the crane chart must be consulted. Everyone, from the crane operator, to the job supervisors, to even the sales guys have to know how to read a crane chart. Here's how.
To illustrate how to read a crane chart, we've chosen the chart for the Terex RT345XL, a rough terrain crane with a maximum lift capacity of 45 tons.
1. DIMENSIONS and WEIGHT — The chart shows the crane dimensions. It includes data for operation with the outriggers extended, transport weight, and steering dimensions. Knowledge of this information is especially critical if the crane will be working in a confined space, as the lifting capacity varies depending on whether the outriggers are extended. The transport weight (below) determines the trailer to be used, how to load the crane on the trailer, the route to take, and what permits are required to get it to the jobsite.
Along the top axis, the first number is the gross vehicle weight. In the other two columns, the arrows indicate the weight load for each axle depending on what additional accessories are loaded.
2. LIFT CAPACITY — This is where the magic happens. In the legend at the top of the chart, you can see these ratings apply when using 6.5 tons of counterweight, with the outriggers extended to 22 x 22.3 feet. Here, you'd graph out the specific lift the crane is needed for. The ft.' indicator on the left axis represents the radius, the distance from the center pin to the center of the load.
EXAMPLE: You need to lift a load of 15 tons (30,000 pounds) a distance of 25 feet. The distance is measured from the center pin of the crane to the center of the load. Once you determine the distance, look on that line for the largest capacity; that will indicate how many feet of boom must be extended. In this case, it is 45 feet.
It's important to note that the maximum capacity is always measured by the shortest lift, usually over the rear of the crane, and with the outriggers fully extended. While the Terex RT345 has a maximum capacity of 45 tons, lifts at any distance or height drops the maximum capacity dramatically.
3. LIFT RANGE — Just as important as lift capacity is lift range. For that, a range diagram is usually included in every chart which illustrates how much boom length is needed to pick up and lift a load both at a distance and at height.
EXAMPLE: You need to pick up a load at 25 feet and lift it to the top of a five-story, 65-foot building. Consulting the range diagram, 69 feet of boom is required to make the lift.
4. LIFT ANGLE — This chart illustrates the maximum lift if a luffing or fixed jib is used. Lifts with jib lengths of 32 and 49 feet (in addition to boom extension of 105 feet) are illustrated. With higher angles of lift, the maximum load capacity decreases. With a luffing jib, the angle can be automatically adjusted from the operators cab. With a fixed jib, of course, the angle is fixed.
5. CRANE IN MOTION — This illustrates the lift capacity for a pick and carry. Here, the chart illustrates the total weight able to be picked up at a 360-degree angle while stationary on wheels, the total weight being able to be supported both while slowly rolling with the load at a zero degree angle (creep), and the total weight able to be supported while moving at 2.5 miles per hour. The column to the left again indicates the radius of the lift, the one to the far right, the maximum boom length each weight can be carried at.

Chicken feathers, as unlikely as it seems, have turned out to be a wonderfully useful material. Among other things, researchers have found they make for great circuit boards and cheap, efficient storage tanks for hydrogen. Now it turns out they could also be used to create biodegradable, petroleum-free plastics.
Researchers at the University of Nebraska-Lincoln say that the protein keratin in chicken feathers, which is strong and durable, as well as the fact that so many of them end up as unused waste, is what makes them such an appealing material. When making the plastic, the scientists heat-treated the feathers to clean them and then pulverized them into a fine powder. They then added chemicals that made the keratin molecules join together into long chains and create a polymer.
The resulting plastic was stronger than other bioplastics made of soy beans or starch and it stood up to water. The material is a thermoplastic which means that heat can be used to mold it into various products and can be melted and remolded many times. It could be used for plastic plates and cups or even furniture and when those things are no longer usable, the plastic is biodegradable.

I'm trying to cut a hole in a mesh to create torpedo tubes on a spacecraft, and am running into a bit of trouble. I can get the hole cut out just fine using Knife Project, the problem, however, is that it completely screws with the shading of the mesh.
Here are the target and pattern meshes:
Here's a detail of the pattern that creates the shape of the outer tube:
and the target mesh:
Target with pattern superimposed
Now, as I said I can cut the hole in the target mesh just fine. The problem is, I get this:
Result Result showing polys
As you can see, cutting the hole in the mesh throws off the smoothing of the mesh, leading to some odd shading which is just unacceptable.
I'm trying to do this with as few extra polys as possible.
Prior to cutting the new geometry the transitions are smooth because the shading is a function of the average face normals connected to each vertex. Because each of those adjacent face normals is different as you go around the surface of the object, the transition is relatively smooth. It's a cheap but effective trick.
Once you start cutting into a face, you get new geometry which has a number of vertices which are surrounded by faces which have the same face normals, therefore the shading is 'flat' on those sections. The transition from surrounding faces onto that flat area is also abrupt, and more prominent with transitions between quads and triangles.
Read Blender docs about custom normals
possible solutions
 1. A way out of that is to carefully adjust the positions of the new vertices such that they follow the inferred curvature, this doesn't have to be exact. as long as you get away from the faces all having the same normals on that spot.
 enter image description here The dark area just below the blue arrow indicates the flow that your geometry would need to have (seen from the side of that edited face). If you can move the internal vertices to match the curvature you'll get reasonable smoothing.
 2. or adjust the vertex normals to follow the curvature, but (May 2015) this is not exposed to the UI, but can be scripted. Manual changes might be overwritten by operations such as remove doubles / recalc normals.
 enter image description here
 3. Normal Edit modifier. It takes a vertex group, and an object, and modifies the normals of the vertices in the vertex group to follow as if they eminated from the center of the object (radial) or directionally if you use a mesh object to help guide the normals.
Blender's Proportional Editing feature can help get nice curvature, but you'll have to experiment with it.
 - $\begingroup$ So if I'm reading you right, this means that even though the vertices are aligning properly on the plane of that particular poly, I'll need to move them inwards or outwards to fit the curvature that the smoothing is simulating? $\endgroup$ – Ambaryerno May 9 '15 at 23:13
 - $\begingroup$ The upside of keeping it lowpoly is that any such intervention isn't going to take too long even if you have to manually adjust the verts or faces. That being said: now i'm wondering if there isn't an add-on for this kind of stuff.. $\endgroup$ – zeffii May 10 '15 at 7:25
 - $\begingroup$ _USER_ probably can be fixed with normal edit modifier copying normals from the original model $\endgroup$ – Denis May 10 '15 at 8:15
 - $\begingroup$ I tried using the Normal Edit modifier after turning on Auto-Smooth in mesh options (which it required). However while Radial and Directional fixed the specific problem I was having, it caused serious issues on OTHER parts of the model. The modifier required me to turn on Auto-Smooth in the mesh options, and I noticed that when I switched from Radial to Directional BEFORE setting a target for Directional, the problem instantly went away. So it looks like just turning on auto-smooth corrected everything. However I wanted to touch base before I decided to just leave it at that. $\endgroup$ – Ambaryerno May 10 '15 at 13:55
 - $\begingroup$ Disregard, it was looking ok from some angles but it's definitely not right on others. AND it screws with the Edge Splitting. $\endgroup$ – Ambaryerno May 10 '15 at 14:10
Zeffi mentioned surface normals and shading. Perhaps you want sharp edges where the hull meets the torpedo launcher. This effect is often achieved using an Edge Split modifier for Sharp edges. You have to leave the Sharp Edges checkbox checked, and then mark those edges in the mesh editor (Ctrl-E > Mark Sharp).
Another thing that sometimes causes strange shading is if the surface normals are flipped. You can check that using the 3d View's N-panel Mesh Display > Normals (pick the Face icon).
 - $\begingroup$ Already made sure the normals are correct, and making a sharp edge around the torpedo tube made no difference. $\endgroup$ – Ambaryerno May 12 '15 at 15:20
I ended up turning on Auto-Smooth and then making the transition between the sides of the hull and the bottom (specifically, the edge along the bottom of the poly in which the torpedo tube was cut) sharp, and that fixed it. It's not exactly how I wanted the contour to look, but it works.
enter image description here
 - 4
 $\begingroup$ show an image :) i'm interested to see what was 'acceptable' $\endgroup$ – zeffii May 12 '15 at 15:29
 - $\begingroup$ _USER_ Added. You'll note I made the transition between the sides of the hull and bottom sharp rather than smooth, and that fixed the shading around the corner and tip of the torpedo tube. $\endgroup$ – Ambaryerno May 13 '15 at 22:59
 - $\begingroup$ Great, that does indeed appear to look good. Marking Sharp edges + Auto Smooth. $\endgroup$ – zeffii May 14 '15 at 4:19
 - $\begingroup$ I was actually able to turn off Auto Smooth and just use the Edge Split modifier once I marked that bottom edge sharp. So it definitely had to do with having a smooth transition between the sides and lower hull. $\endgroup$ – Ambaryerno May 15 '15 at 0:19

connecting food with people
Some organisations, such as Pret a Manger (donor), FoodCycle and Fareshare (receivers) are already working to reduce their food waste and converting surplus food into meals for people who need it. However, there are still many more who don't know this is possible and are not aware of the existing different solutions for different needs, such as scale of the business, type of food, location of a store and restaurants.
It was found that there are several ways to address this issue and what is missing is the inspiration and information to create the links between each particular case and what can be done.
Stage 1: collect information:
Identify businesses and organisations which can donate surplus food and organizations/projects which can receive it
Classify/categorize solutions, define characteristics of donors and recipients
Stage 2: disseminate information:
Create an online map, link donors and recipients who are in close proximity
Run campaign to drive-up adoption and engage local communities
As the concept is proved, the team are working on consolidate knowledge and operational model:
Keytree has redesigned the map, with user direct input and more advanced technology, including automated matchmaking system and communication system to streamline surplus food donation process (new platform to be launched early 2015)
Stage 3: reward and recognition
Launch a Zheroes Index:
Increase visibility and reward best practice
Help councils and citizens promote a healthier neighbourhood
Having created the initial map with 500 entries, further investment will be used to extend the map to engage volunteers and transporters able to overcome logistical barriers, expand coverage across London and other parts of the UK/the World. The PZ solution is evolving from an online tool towards an online community, and toolkits are being developed to empower citizens and communities to grow Zheroes local initiatives.
The aim is to provide the use of the digital platform for free to any user, and develop revenues from professional services to support organisations to overcome their operational and cultural barriers to donate/receive surplus food. Plan Zheroes aspires to become the knowledge hub for surplus food in the UK.
As an example, current knowledge allowed Plan Zheroes create the _URL_ at the request of the GLA to guide citizens and advisors to identify reliable providers of low cost and free food in London.
Plan Zheroes has been advising Sustain/FoodSave in food waste prevention and how to set up surplus food donations. They would also like to convert a bus into a mobile kitchen/restaurant which could use surplus food and promote Plan Zheroes in London
The team have a new partnership with NUS (National Students Union) to roll out a national programme help set up Student's led food redistribution schemes; with Sustain/FoodSave programme they helped set up and coordinate the food donations from Borough Market (where in 20 weeks we rescued 5 Tonnes of Surplus Food from 4 bakers and 3 vegetable traders), they have started a new partnership (through an RSA Fellow Michael King), which the new platform will be trialled to support OASIS/We Believe programme in Liverpool growth plan. We have been awarded a grant from Garfield Weston, and Maria Ana is currently at the SSE/Lloyds Bank Start-Up programme.

Mining Publication: Injury Analysis of Pennsylvania Small Surface Coal Mines
This paper is a descriptive analysis of injuries and fatalities at small surface bituminous coal mining companies in Pennsylvania. The purpose of analyzing a specific industry sector and location is to identify issues that might be missed in a wider analysis. Other studies of small mine safety (e.g., Peters and Fotta, 1994, Randolph and Boldt, 1997) have shown that the relationship between safety and mine size is not a simple one. Some injury types occur at higher rates at small mines, while others occur at lower rates. Consequently, an analysis limited to a specific type of mining can help identify hazards and issues specific to that sector. The results of this analysis will be useful for directing training, intervention, and research efforts towards the most prevalent causal factors and incident types.

Vacuum frying refers to dehydrate food in a negative pressure environment.
Generally, the frying temperature is between 80 to 120 ℃, which can effectively reduce the damage of high temperature to food nutrients. The vacuum fried product has lower oil content and is healthier.
01. KEEP FRESH FLAVORS
Most of the flavors in the fresh materials are water-soluble and do not dissolve in the oil, vacuum frying is carried out at a hermetically sealed vessel, these flavors are further concentrated.
02. COLOR PRESERVING
The vacuum frying temperature is 80~120*C, and the oxygen absence in the vacuum fryer. Fried food is not brown. For example, kiwifruit is easily browned by heat, and it can keep its green color if it is fried in vacuum.
03. CRISPY AND DELICIOUS
In vacuum, the moisture in the intercellular space of fruits and vegetables vaporized and expands rapidly, the vacuum fried snacks are crisp and delicious, and has excellent rehydration performance.

How many valence electrons does scandium have?
Quick Answer
Scandium, element 21 on the periodic table, has 2 valence electrons. Valence electrons are the electrons that occupy the highest energy orbital of an atom. They are the electrons in an atom that participate in chemical reactions.
Continue Reading
Full Answer
Scandium's electron configuration is [Ar] 3d1 4s2. The 4s orbital is the one that houses its valence electrons. Since valence electrons are the primary electrons involved in chemical reactions, they are a key factor in determining an element's chemical properties. Elements in the same column, or group, of the periodic table have the same number of valence electrons, so they frequently have similar chemical and physical properties; scandium is a group 3 element, and it shares many physical properties with other group 3 elements, such as lutetium and yttrium. For example, these elements have very similar melting points.

Bash: some useful "set"
» Votes: 2/2
When using Bash, you can change the default behavior of the script/shell by
set command. Example
set -e: The script/shell will exit immediately if a simple command exits with a non-zero status, unless the command that fails is part of an until or while loop, part of an if statement, part of a
||list, or if the command's return status is being inverted using
set -C: Prevent output redirection using
from overwriting existing files. You need to use, for e.g,
tee -a, if you really want to overwrite some file.
set -u: Treat unset variables as an error when performing parameter expansion. An error message will be written to the standard error, and a non-interactive shell will exit.
set -x: Print a trace of simple commands and their arguments after they are expanded and before they are executed. This is very useful when debugging your script, though it is not really helpful in many cases.
set -u is very useful and it's highly recommended when your script/shell is running as
root. For example, if you invoke
rm -rfv /$_MY_DIR/etc/ and if the variable
$_MY_DIR isn't defined (unset), your script is simply executed as
rm -rfv /etc/ -- this is dangerous as that means that you delete all configuration on your server. Please note that, an unset variable isn't an empty variable. (A defined variable is DEFINED but it may as an EMPTY VALUE.)

The Spallation Neutron Source (SNS) is a facility being designed for scientific and industrial research and development. The SNS will generate and employ neutrons as a research tool in a variety of disciplines including biology, material science, superconductivity, chemistry, etc. The neutrons will be produced by bombarding a heavy metal target with a high-energy beam of protons, generated and accelerated with a linear particle accelerator, or linac. The low energy end of the linac consists of, in part, a multi-cell copper structure termed a coupled cavity linac (CCL).
The pressure of the cryogen within a Dewar determines the operating temperature since the cryogen is typically in a saturated state. Thus, the operating temperature of a Dewar is directly related to the ambient pressure external to the Dewar and the flow losses associated with venting cryogen. Given the low vapor pressures of some cryogens, such as solid hydrogen, the vent flow from Dewars used in space can enter the transitional and molecular flow regimes.


Gender, political knowledge and descriptive representation
Successive studies have found a persistent gender gap in political knowledge. Despite much international research, this gap has remained largely impervious to explanation. A promising line of recent enquiry has been the low levels of women's elected representation in many democracies. We test the hypothesis that higher levels of women's elected representation will increase women's political knowledge. Using two large, comparative datasets, we find that the proportion of women elected representatives at the time of the survey has no significant effect on the gender gap. By contrast, there is a strong and significant long-term impact for descriptive representation when respondents were aged 18 to 21. The results are line with political socialization, which posits that the impact of political context is greatest during adolescence and early adulthood. These findings have important implications for explaining the gender knowledge gap, but also for the impact of descriptive representation on political engagement generally.

Effect of helium on irradiation-induced hardening of iron: A simulation point of view
Irradiation-induced hardening and loss of ductility of ferritic/martensitic materials envisaged for future fusion reactor is still difficult to understand. In particular, helium (He), produced by transmutation by the fusion neutrons of 14 MeV, is known to impact mechanical properties, but its effect at the microstructural level is still unclear. Molecular dynamics simulations of the mobility of an edge dislocation in iron (Fe) are performed to study the effect of He, either as a gas in solid solution or in cavities. Obstacle to the dislocation, the cavity, in the form of a void or a He bubble, is compared to a ao dislocation loop, all being 2 nm in size. Results show that He in solid solution up to 1.0 at.% has a little effect on the dislocation mobility. Conversely, the cavities and the ao [10 0] dislocation loop are strong obstacles to the passage of the edge dislocation. Interestingly He bubbles present a lower obstacle strength than voids for low He contents, while for high He content the bubble promotes loop punching, which induces a strong resistance to the passage of the dislocation.

Map of Alberta Townships in Canada
You can easily create a map of Alberta Townships in Canada using Mapline. The township system was first introduced in Canada in the late 1700s. Township is the basic land survey division of land. It refers to the district or area associated with a town. Using Mapline, you can easily create a map of Alberta townships in Canada. In Alberta province, townships are not used in administrative units. Rather, they are used for the purpose of land division by Dominion Land Survey. They are recognizable by their township number and range number.
Steps to Create a Canada Township Map
- Create a Mapline account and login.
- Click the orange "Add New Items" button.
- Select "New Map" on the drop down arrow.
- Give your map a name and click "OK."
- Click the "Add" button from the left sidebar.
- Select the "Territories" option.
- Click "From Mapline's Repository."
- From the "Territories" select "Canada Townships – Alberta."
- Select how you want your boundaries to be colored in "Fill Color" (Random Colors, Uniform Color, Dynamic heat map colors, or Custom colors from spreadsheet).

In a peel test, energy is applied to the system in order to separate the adhesive (and its backing) from the substrate. Ideally, all this energy is applied to the adhesive-substrate interface, so that by measuring the applied energy, you then have a value of the strength of that adhesive bond. That however, is not the case in any real system.
Some of the energy applied to the system is spread to other components of the system and does not go to the adhesive-substrate interface. These other components include the part of the adhesive not at the adhesive-substrate interface and also the backing.
Adhesives in general and pressure-sensitive adhesives in particular are made from soft materials which absorb energy. In a peel test, a good amount of the applied energy will be used to first deform the bulk of the adhesive prior to any energy being applied to the adhesive-substrate interface. This is the reason that thicker layers of adhesive have stronger bonds – the actual bond at the interface is identical, but the extra amount of adhesive adsorbs more applied energy. More energy is needed to break the bond. More energy = stronger bond.
Foam adhesives (whether the adhesive is foamed itself or applied to both sides of a layer of foam) are another example of this. The foam absorbs a terrific amount of energy so that the interface doesn't.
A similar issue occurs with the backing – it too must be deformed during the peel test and this deformation requires energy. The stiffer the backing, the more energy that must be applied to deform it.
Both of these deformations then represent energy sinks that make it more difficult to understand the results of any peel test. If a consistent backing is used, and if the adhesive thickness is the same, then it is possible to make comparisons between different adhesives. The energy sinks still exist, but they have become standardized.
Additionally, it is possible with very stiff substrates that the energy sinks will consume such a large fraction of the applied energy (90% +) that the energy applied to breaking the adhesive-substrate interface will be lost in the noise of the measurements. That's when you need to find another test.

What is the conjugate training system?
Also known as the "Westside Method" because it was devised by Louie Simmons of Westside Barbell gym in Columbus, Ohio, the conjugate training system has its roots in powerlifting. However, the effectiveness of this program extends well beyond the world of powerlifting.
I first began training the conjugate method for powerlifting purposes, but quickly saw that it had a great carryover when training youth athletes. Why? Well, beyond the fact that the method gets results, young people have a tendency to get bored. The conjugate system sees you utilize the same movement pattern over and over, but frequently varies how you train that pattern. So while you may know that the "main" lift in a given workout will be a squat, it could be a Front Squat, Zercher Squat, Back Squat, etc. This constant variety keeps things interesting and also allows new PRs to be set quite often (since the more exercises you train, the more chances for PRs you give yourself).
This article is intended to be a basic primer on the conjugate training system. I'd like to outline the basic premise of the program and the reasons I believe it to be beneficial, and if it sounds like something that might intrigue you, I'd encourage you to research it further.
So what exactly separates the conjugate method from any other training system? It's attention to detail and accessory training. The conjugate method breaks training down into 4-5 weekly training sessions:
- maximum effort upper (Bench Press)
- maximum effort lower (Squat and Deadlift)
- dynamic effort upper
- dynamic effort lower
- one extra day for posterior chain and weak point training
Let's say you're training the Bench Press for max effort. You'll begin with a quick warm-up routine followed by lifting a Bench Press variation until you reach a one-rep max. As soon as the max is reached (without failing), you'll move on to accessory training. Accessory movements should make up roughly 80% of your session. Here's a quick mock-up of a max effort upper training day in the conjugate training system:
- Barbell Floor Press x 10/8/6/4/2/1/1
- Strict Pull-Ups 4x8
- Rope Face Pulls 4x12
- Tricep Skull Crushers 4x10
- Bicep Hammer Curl 3x15
As you can see, only 20% of the workout is barbell-specific work used to train the main lift. The remaining 80% is made of specialty exercises trained for volume to help build the supporting muscles of the main lift. Repeat in similar fashion for the lower body max effort day, remembering to rotate through variations of the main lift and accessory lifts.
So how do I train on the dynamic effort days?
Dynamic effort is essentially training a load that is less than your one-rep max for maximum speed. In similar fashion to the max effort, you'll train a barbell lift followed by accessory movements. The barbell lift will vary similar to max effort, but you'll choose a percentage of your max to train as fast as possible while maintaining good form.
It's important to note that the separation of max effort and dynamic effort should be approximately 72 hours. If you train max effort lower body on Tuesday, the dynamic lower body should be on Friday to allow for adequate recovery. I believe that the dynamic effort is key in building explosive power in athletes, because it forces the athlete to move a sub-maximal weight with the highest rate of force possible. In order to continually progress, the percentage should raise roughly 5-10% each training session until a new max is established.
For example, a person with a 400-pound squat max would squat 50% (200 pounds) week one, 55% (220 pounds) week 2, and 60% (240 pounds) week 3. These percentages can be changed to ensure the athlete is moving the bar with max force. Accommodating resistance can also be added by rotating various bands and chains to the bar. If you decide to add bands or chains, lower the bar weight, but make sure the bar and accommodating resistance don't total more than 60-80% of your max. If you have a 400-pound Squat max, the total weight of the bar and the accommodating resistance should never exceed 320 pounds.
The conjugate training system places a high priority on physical preparedness. Sled Walks, Lunges, Jumps and Carries ensure that the athlete is prepped and ready for their given event. The system is also easy to scale for novice athletes; if you're not able to bench with proper form, Chin-Ups, Push-Ups or dumbbells can replace the barbell lift. For lower body; swings, jumps and bounds can replace the Squat and Deadlift.
The conjugate system is great at allowing the coach and athlete to design a program that fits the athlete's specific needs. Instead of opting for a one-size-fits-all training system, the conjugate method can easily accommodate an athlete who has a weak low back or hips by swapping in exercises to address their individual needs. By changing the variation on max effort days, you allow the athlete to set a new PR each session, allowing them to physically and mentally become a stronger athlete.
Here's a sample week of the conjugate program:
Monday: Max Effort Upper
- Incline Barbell Bench up to a 1 rep max
- Lat Pulldowns 4x12
- Shrugs 4x8
- Tricep Rollbacks 3x20
- Planks 3 x 45 seconds
Tuesday: Dynamic Lower Body
- Box Back Squat (using 50% of Back Squat 1-Rep Max) 8x2
- DB RDL 3x15
- Goblet Squat 3x12
- Box Jump 30 total reps
- Palof Press 3x10 each side
Wednesday: Off Day
Thursday: Dynamic Upper Body
- Barbell Bench Press (using 50% of 1-Rep Bench Press max) 6x3
- DB Floor Press 4x12
- 1-Arm DB Row 4 x 8 each side
- DB Hammer Curl 4x12
- Close Grip Push Up 3 x Failure
Friday: Max Lower Body
- Sumo Deadlift up to a 1 rep max
- Heavy DB Lunge 4x8 Each
- Band Hamstring Curl 4x15
- GHR 3x10
- Ab Wheel 3 x Failure
Next time you're searching for a system that'll make training exciting while also catering to the needs of your athletes, consider the tried and true conjugate method!

STRAWSCRAPER – an urban power plant
STRAWSCRAPER is an extension of Söder Torn on Södermalm in Stockholm. With its new energy producing shell covered in straws the building can now recover wind energy and thus works as an urban powerplant. What was originally planned to become a building of 40 flights became 26. Söder Torn was finalized in 1997, however, the architect Henning Larsen had already left the contract after having lost influence over the design of the tower.
Belatchew Arkitekter wants to give Söder Torn its original proportions and at the same time explore new techniques that could create the urban wind farm of the future. By using piezoelectric technology a large number of thin straws can produce electricity merely through small movements generated by the wind. The result is a new kind of wind power plant that opens up possibilities of how buildings can produce energy. With the help of this technique, surfaces on both old and new buildings can be transformed into energy producing entities. Furthermore, an additional aspect is revealed when the constant movement of the straws creates an undulating landscape on the facades. What is usually considered to be the most static of all things, the building, suddenly comes alive and the construction gives the impression of a body that is breathing. The straws swaying in the wind gives the building a constantly changing facade further reinforced at nighttime with lighting in changing colors.
The straws of the facade consist of a composite material with piezoelectric properties that can turn motion into electrical energy. Piezoelectricity is created when the deformation of certain crystals is transformed into electricity. The technique has advantages when compared to traditional wind turbines since it is quiet and does not disturb wildlife. It is operable at low wind velocity since only a light breeze is sufficient for the straws to start swaying and generate energy. The existing premise on top of the building is replaced with a public floor with room for a restaurant. The new extension creates, apart from the energy producing shell, room for the citizens with the possibility to reach a lookout platform at the very top of the tower. Here you will be able to enjoy an unmatched view of Stockholm.

Propofol detection and quantification in human blood: the promise of feedback controlled, closed-loop anesthesia
The performance of a membrane-coated voltammetric sensor for propofol (2,6-diisopropylphenol) has been characterized in long term monitoring experiments using an automated flow analytical system (AFAS) and by analyzing human serum and whole blood samples by standard addition. It is shown that the signal of the membrane-coated electrochemical sensor for propofol is not influenced by the components of the pharmaceutical formulation of propofol (propofol injectable emulsion). The current values recorded with the electrochemical propofol sensor in buffer solutions and human serum samples spiked with propofol injectable emulsion showed excellent correlation with the peak heights recorded with an UV-Vis detector during the HPLC analysis of these samples (R2 = 0.997 in PBS and R2 = 0.975 in human serum). However, the determination of propofol using the electrochemical method is simpler, faster and has a better detection limit (0.08 ± 0.05 μM) than the HPLC method (0.4 ± 0.2 μM). As a first step towards feedback controlled closed-loop anesthesia, the membrane-coated electrochemical sensor has been implemented onto surface of an intravenous catheter. The response characteristics of the membrane-coated carbon fiber electrode on the catheter surface were very similar to those seen using a macroelectrode.

But behind these similar rates hide two very different labor markets. Unemployment duration in Portugal is more than three times that of the United States. Symmetrically, the flow of workers into unemployment in Portugal is, in proportion to the labor force, less than a third of what it is in the United States. Relying on evidence from Portuguese and U.S. micro data sets, we show that these lower flows come in roughly equal proportions from lower job flows, and from lower worker flows relative to job flows. We then argue that these differences plausibly come from high employment protection in Portugal. We finally show how, looking across countries, higher employment protection is associated with lower flows and higher unemployment duration. In short, high employment protection makes economics more sclerotic; but because it affects unemployment duration and flows in opposite directions, it has an ambiguous effect on the unemployment rate.}, }
