Non-Profit Spotlight: Devon Wildlife Trust
By Jessica Hardesty Norris
As an appreciation for beaver as wildlife outstripped the appetite for hats and clothing made with beaver fur, Europe has initiated reintroductions across the continent. The pilot project to bring the mighty rodent back to the British Isles is somewhat on the tail end of that activity. Unlike other parts of Europe, which have quickly growing beaver populations, the English landscape is more challenging, with fewer natural areas and more barriers to connectivity. Peter Burgess, the Director of Conservation and Development for the Devon Wildlife Trust (DWT) and self-described keen enthusiast of beavers, is undaunted. DWT has been spearheading a strengthening collaboration to bring wild beaver back for over seven years. It's a short period compared to the 400 years since wild beaver were hunted to extinction from the island, but things are moving fast.
"We started to see a groundswell of public support for the idea," says Burgess. "And it became apparent that Devon would likely be in the spotlight." Compared to other regions of England that are more highly constrained by development and their inherent or altered ecological context, Devon presents advantages for beaver reintroduction. A pastoral landscape with a mild, wet climate, Devon has lower population density. It also hosts remnant Culm grassland systems, which depend on poorly drained acidic and clay soils that retain water and stay too wet for modern farming practices. Maintained by grazing and occasional managed burning, Culm grasslands support a unique community of plants and animals, including a highly endangered species of butterfly, the marsh fritillary. More than half of the original grassland extent has been lost since the 1980s, mostly as land was drained to allow for agricultural improvement. Given this context, Burgess and others felt that beaver could likely serve as a natural mechanism to restore the hydrology and thereby the former Culm grasslands through their coppicing activity.
By 2011, the Wildlife Trust had constructed a three-hectare fenced area where beaver could be released and studied to understand their capacity as landscape engineers. This project was a first step along a road to reintroduction, a chance to examine the efficacy of beaver as a wet grassland management tool, introduce stakeholders to a concrete example of their effects, and build popular support for reintroduction efforts. The results have been promising.
Devon Wildlife Trust was merrily proceeding with the enclosure experiment when there was an unexpected development that offered an opportunity to fast-forward the overarching program. They heard and confirmed reports that beaver of unknown origin were busily building dams outside the enclosure, along the nearby River Otter. Though their provenance remains a mystery, they are thought to be animals from a private collection that had either escaped or were released into the area.
"Hearing about those introduced beaver gave us an amazing opportunity to crack on with the process of understanding the public sentiment and regulatory framework for beaver reintroduction," says Burgess. The mystery beavers posed an interesting problem: because beaver can carry a potentially damaging tapeworm (Echinocochus multilchularis), they needed to be tested.
Once they were captured for testing, their legal status posted specific challenges. Captive beavers, which they now were, are not allowed to be released into the wild. Even where legal, such releases are carefully managed according to established guidelines from the IUCN. So once the beavers were given a clean bill of health, DWT saw their situation as an opportunity to generate public awareness and a chance to pioneer the process of securing legal authorization for their release.
DWT initiated a massive outreach campaign that built on the relationships they had developed while securing permission and buy-in for the enclosure experiment. DWT knocked on doors of local landowners and farmers, appeared at public meetings, sought opportunities to speak to community groups, and began to untangle the concerns of stakeholders and other parties who resisted the notion. Eventually the regulators from Natural England Department for Environment, Food, and Rural Affairs, who worked closely with DWT and other experts from the start, decided that the mystery beavers could be rereleased as an independent trial, lasting five years. The solution required DWT to reframe its approach.
"We started out campaigning for the re-release, but that role has shifted in that we are sharing responsibility for supervising an independent research study," says Burgess. "We have permission to add additional animals. After five years, we will face a decision about how to proceed."
This facet has important implications for the team's decisions today, which is roughly the midpoint of the trail period. A tiny population of beaver, left to breed amongst themselves for even five years, will undergo inbreeding and have a very restricted genetic diversity. Would that mean that if the trial is successful, a thoughtful reintroduction program should not begin with the population already living in the wild? The nine beavers found today in the River Otter are believed to have a common parent. In England, there is no studbook for the beavers. Most animals in England today have come from areas in Bavaria, Germany, and Norway.
"Genetic diversity is something we are trying, retrospectively, to improve," says Burgess. Another challenge that has to be worked out centers on how the animals will be managed if they cause trouble for humans or infrastructure. DEFRA must decide how to respond if the beaver build dams that increase local flood risk, for example. The answers are starting to become clearer through the listening sessions and conversations occurring today. The hard data on the water quality and quantity changes are captured by the research enclosure, but the situation of the mystery beavers has quickly advanced everyone's understanding of potential socioeconomic impacts, such as changes to land immediately adjacent to the river that would prevent its use for agriculture. Most social considerations, though, are rapidly becoming less complex.
"The nearby communities are amazingly supportive," says Burgess. Neighbors describe their enthusiasm for the program, and their sense that they are proud to see the beavers coming back to the landscape. This has been a welcome insight to Burgess, who is resolutely optimistic about the future of the program. "England has so little natural vegetation and so few unaltered ecosystems. We now have a chance to enable beavers to breathe new life into our waterways and provide them with more space to behave in much more dynamic, complex, and ecologically beneficial ways – and whilst doing so reduce flood risk to communities downstream and improve the quality of water."
The River Otter Beaver Trial is led by Devon Wildlife Trust working in partnership with The University of Exeter, the Derek Gow Consultancy, and Clinton Devon Estates. Expert independent advice is also provided by the Royal Zoological Society of Scotland, Professor John Gurnell, and Gerhard Schwab, an international beaver expert based in Bavaria. Their funding support, however, comes entirely from individuals and foundations. Click here for more info. [hyperlink _URL_

World's First Chemistry on a Chip "Chem Chip™". Interested industrialists within the energy, chemical or fuels space will find our Chemistry on a Chip "Chem Chip™" of interest at multiple strategic levels and within several time domains.
Chemistry on a Chip™ or "Chem Chip(s)™" are solid-state chemical cells that upgrade existing refinery and petrochemical plants to solid-state chemistry and de-couple their dependence on crude oil. Use cases for a Chem Chip™ include, "Refinery on a Chip™" and "Plant on a Chip™" for production of more than one carbon molecule.
Chem Chips are built with trillions of nanoscale spikes that concentrate the electrical field to enable 12 electron direct reactions. Think of this innovation as an industrial scale version of nature's enzymes that focus electron transfer. However, life in nature's mission is to live first and not make products. Our Chem Chip's mission is to make products first as it does not require biological life to run the reaction within such an intense electrical field created on the Chem Chips.

Colorado to study oil and gas emissions
Colorado officials are launching a study of emissions tied to oil and gas development following a hearing by regulators that questions the science needed for making rules.
The project is expected to provide information about how oil and gas emissions travel and their behavior in areas along the northern Front Range, which has become a hotbed for drilling. A second phase is expected to assess possible health effects.
Officials said Wednesday that testimony during this week's Colorado Oil and Gas Conservation Commission rulemaking hearing reinforced views of industry and environmental experts that better science is needed related to oil and gas emissions.
On Monday, the commission approved rules making the state one of the first to require energy companies to do groundwater sampling both before and after they drill.

We hear many statements that a woman should earn money herself, so the question of whether this is so is sharply raised. We decided to find out if this statement is true and how to achieve the desired goal.
These are the 5 main reasons why a woman should earn money herself
You can not meet the expectations of others.
As a rule, money gives a sense of power. Most often, using the means of their parents or partner, many people feel driven and dependent. They spend other people's money, which means they have to put up with the whims of another person. Any disapproval creates a sense of anxiety and reduces the sense of confidence. When they fail to live up to expectations, a bitter sense of guilt appears in their soul. It is this imposed sense of guilt that often leads to unpleasant consequences. With the advent of your own money, you can forget about it. A person blossoms and begins to live, not exist indeed.
The ability to express your position, including in clothing.
For a woman, appearance is significant. Of course, the original purpose of clothing is protection and warmth. However, when the fundamental needs of Maslow's pyramid are closed, a person no longer needs to survive. The image comes to the fore, which acts as a way to visualize your inner world, demonstrate your individuality, and establish interaction with the outside world. You can feel more confident, relaxed and free by choosing what you like. On the contrary, melancholy and impotence will cover your head if you have to put up with what you don't like.
You don't have to take on a job you don't like.
An unloved job or household chores are daily chores that take energy. Often, household chores are an endless waste of time, and the result of this work can be challenging to see. It seems that you just cleaned up and redid everything you need, as the next day, you can start all over again. And so on in a circle. Naturally, this isn't very pleasant. Because of the numerous routine tasks, there is a massive drain of energy that can be spent on essential things or just spending time with loved ones. With the help of money, you can solve these issues in one fell swoop. For example, you can use the services of a housemaid, order ready-made food, hire an assistant who will help you do the hated work, and so on.
Engage in creativity and self-development.
What kind of acting skills, dancing and going to concerts can we talk about when you need to pay off your communal apartment and close your debts? As a basis, we again take the Maslow pyramid. Initially, it is essential to deal with the primary needs and only then move on to a new level. Conscience or limited resources will always prevent creative expression. And without it, the brightness and taste of life, freedom and diversity are lost. If a woman earns her own money, she can afford much more, dramatically affecting her inner confidence and interaction with people.
Change your environment to a strong community.
You cannot avoid some challenges on the path of quantum leap and development. You have to face difficulties that can become a springboard before taking off. One of them is changing the environment. In other words, your thinking, interests, priorities, and values may also change when you move to a new financial level. Like attracts like, so there are new charged people in the environment who strive for their dreams and make progress. It is difficult for the old environment to understand, for example, why spend a lot of money on luxury housing when you can live like everyone else in an ordinary apartment, why buy delicacies when there are products for promotions, and so on. And it will always be so. Therefore, there must be those whose thinking and priorities will be the same. The same goes for relationships. Both must be on the same level in a couple; otherwise, it will be challenging to avoid misunderstandings and conflicts.
And most importantly, money gives you a sense of freedom. The opportunity to feel like who you are. To be yourself, you should start changing your financial thinking and income level.

Given a measure space $X$ with its measure $\mu$, it can be shown (I'll provide a proof if asked for) that $\displaystyle \forall f \in L^\infty(X,\mu),~\textrm{if } \exists p_0:\forall q \geq p_0, f\in L^q\cap L^\infty, \textrm{ then } \lim_{p \to \infty}\|f\|_p = \|f\|_\infty$ (whih by the way justify this notation)
This convergence implies the following: $\forall f, \forall \epsilon > 0, \exists q:= q(f,\epsilon),\textrm{ such that } \forall p\geq q, |\|f\|_p-\|f\|_\infty| < \epsilon$
This means that given an approximation error of the infinity norm bounded by $\epsilon$, I should be able to compute an (let's call it) index so that, I don't need to go any further, but I have a priori knowledge of the potential error.
The idea is, I am working on some pattern recognition problems and I am using the infinity norm somewhere there. However, as it is quite unreliable against outliers, using a p-norm approximation allows to "average out" the local outliers and get a more robust result. The higher the power the more importance the local outliers (or singularities) have, and the less I like it :)
If you have any idea on a proof or a results, it would be very helpful.

In general it sounds not too good to "average" outliers (since they are outliers and hence, distort the mean quite heavy). How about calculating the infinity norm, but leaving out a few of the largest contributions? – Dirk Mar 22 '12 at 10:08
Well, even though some points can be considered as outliers, they may carry a bit of information anyway, or we cannot distinguish if they proper information carrier or information destroyer sometimes (see for instance the problems in OCT imaging). As a basic example, you can think of the Hausdorff distance in image alignment:… The two sets seem to be pretty well aligned, if we take out the peak, but taking this peak into consideration tells us also that the shapes are quite different. – Jean-Luc Bouchot Mar 22 '12 at 10:38

Our encoding for encrypted filenames is now open source
Why do Boxcryptor's encrypted filenames consist of Chinese characters? This is a question we often hear about our folder and filename encryption and today we want to give you a detailed explanation.
Filename Character Limit
The underlying problem in choosing the appropriate font is the character limit. Core elements of Microsoft Windows can only handle file paths with a length of maximum 256 characters. This limitation is relevant, for example, when using Windows Explorer. Since files with longer paths would therefore not be accessible, many cloud providers—Dropbox, for example—don't synchronize files with a path length of more than 260 characters.
However, encrypted filenames require even more bytes than plaintext filenames. Thus, we had to find a way to reduce the character count of encrypted filenames, so Boxcryptor would not constantly trigger sync issues.
The solution to this problem is to use Unicode characters instead of ASCII characters. While an ASCII character can only transport 1 byte of information, a Unicode character transports 4 bytes. Thus, for every 4 ASCII characters there is 1 single Unicode character.
Comparable to already existing methods for encoding like Base64, we have developed the binary-to-text method Base4K, which uses 4000 different Unicode characters. While Base64 requires more characters than bytes, Base4K requires fewer characters than bytes. Base4K is more than 50 percent more effective than Base64 in terms of character length.
So why do we use Asian characters for Boxcryptor? The answer is quite simple: We need 4000 different characters and there are just not enough ASCII characters in the Latin alphabet. Also, the required elements additionally had to meet several technical specifications:
- Consecutive points in the Unicode system
- Universal representability (this is not the case, for example, with some symbols such as control characters)
- Unambiguous distinguishability
The large size of the Asian character set proved to be perfectly suitable here. Base4k therefore maps bytes (0x00-0xff) to Unicode points in the ranges 0x4000-0x40ff and 0x6000-0x6fff. Thus, the selection was based solely on technical requirements.
The Asian character set contains many times more symbols than the Latin alphabet. Therefore, it is perfectly suited for our encoding of folder and file names. However, real Asian (e.g., Chinese) file names would look completely different, since the encoded symbols follow neither syntax nor language logic.
By the way: If you use Boxcryptor to encrypt files and folders with real Asian names, you should have no problem in most cases. "Normal" Chinese file names, for example, do not correspond to the structure of encrypted Boxcryptor file names, for example. Accordingly, they are not recognized as such. In the unlikely event that Boxcryptor misinterprets a file as encrypted, you can simply enable the "show also non-decryptable files" setting. This will also display misinterpreted, "real" file names normally.
Now Also Open Source
By the way, although we will not publish the source code of Boxcryptor in its entirety, we have also added a sample implementation of the Boxcryptor encryption algorithm on Github.

Electrostatics of polymer translocation events in electrolyte solutions
journal contributionposted on 19.01.2018, 14:10 authored by Sahin Buyukdagli, Tapio Ala-NissilaTapio Ala-Nissila
© 2016 Author(s).We develop an analytical theory that accounts for the image and surface charge interactions between a charged dielectric membrane and a DNA molecule translocating through the membrane. Translocation events through neutral carbon-based membranes are driven by a competition between the repulsive DNA-image-charge interactions and the attractive coupling between the DNA segments on the trans and the cis sides of the membrane. The latter effect is induced by the reduction of the coupling by the dielectric membrane. In strong salt solutions where the repulsive image-charge effects dominate the attractive trans-cis coupling, the DNA molecule encounters a translocation barrier of ∼10 kBT. In dilute electrolytes, the trans-cis coupling takes over image-charge forces and the membrane becomes a metastable attraction point that can trap translocating polymers over long time intervals. This mechanism can be used in translocation experiments in order to control DNA motion by tuning the salt concentration of the solution.

Teachers' Awareness of Their Diverse Classrooms: The Nature of Elementary Teachers' Reflections on Their Science Teaching Practice
Action in Teacher Education
This multiple case study examined the reflections of elementary teachers as they taught science to English language learners (ELLs). The six participants in this study developed explanations about their science teaching with ELLs as they engaged in reflective practice using video-based tools during a professional development experience. Open coding was used to analyze the data and cross-case comparison identified similarities and differences among the participants' cases. Participants' reflections indicated that knowledge of their students' culture and backgrounds influenced their teaching practices and the focus of their reflections. Themes that emerged from participants' reflections related to navigating the school world, managing the technical classroom, negotiating barriers, nurturing all students, and understanding learning. Findings illustrate the importance of examining teachers' reflective writings in order to develop an understanding of how they use students' backgrounds to inform their teaching practice and how they develop their science teaching practice with ELLs.

The ability to adapt is critical to survival and varies between individuals. Adaptation of one motor system may be related to the ability to adapt another. This study sought to determine whether phoria adaptation was correlated with the ability to modify the dynamics of disparity vergence. Eye movements from ten subjects were recorded during dynamic disparity vergence modification and phoria adaptation experiments. Two different convergent stimuli were presented during the dynamic vergence modification experiment: a test stimulus (4° step) and a conditioning stimulus (4° double step). Dynamic disparity vergence responses were quantified by measuring the peak velocity (°/s). Phoria adaptation experiments measured the changes in phoria over a 5-min period of sustained fixation. The maximum velocity of phoria adaptation was determined from an exponential fit of the phoria data points. Phoria and dynamic disparity vergence peak velocity were both significantly modified (P < 0.001). The maximum velocity of phoria adaptation was significantly correlated with the changes in convergence peak velocity (r > 0.89; P < 0.001). There was a strong correlation between the ability to adaptively adjust two different oculomotor parameters: a tonic and dynamic component. Future studies should investigate additional interactions between these parameters, and the ability to adaptively change other oculomotor systems such as the saccadic or smooth pursuit system. Understanding the ability to modify phoria, dynamic disparity vergence, and other oculomotor parameters can yield insights into the plasticity of short-term adaptation mechanisms.

Dickinson State University (DSU), located on the edge of the North Dakota Badlands, strives to be a premier university in the Upper Great Plains. DSU is also the physical home of the Theodore Roosevelt Center.
To celebrate the centennial year of Theodore Roosevelt's birth in 1958, a Theodore Roosevelt Centennial Commission was created by the United States House of Representatives. The Commission worked with the Theodore Roosevelt Association to coordinate activities to commemorate the anniversary of Roosevelt's life. In observation of the centennial, Dickinson State University, then Dickinson State Teacher's College, organized a symposium to honor Roosevelt's memory and to give recognition to the role North Dakota played in his life. The symposium theme was Responsible Citizenship, and the keynote speakers included Senator John F. Kennedy, Howard K. Beale, Hermann H. Hagedorn, Secretary of the Interior Fred A.

 In certain circumstances, the nCipher MSCAPI CSP Install Wizard support
 software on Windows 2000 will set the nCipher CSP key generation
 behavior incorrectly. Despite the user requesting Operator Card Set
 protection for keys ('cardset protected keys') that are generated using
 the nCipher CSP, a software error might result in keys being protected
 by the module alone.
 1. Security world
 nCipher's key management modules (nForce/nShield) are generally
 used with nCipher's suite of utilities for managing a 'security
 world'. A security world is a collection of cryptographic keys,
 smart cards, modules and associated data stored on host computers.
 A security world is designed to prevent unauthorized access to
 application keys while maintaining scalability and key availability.
 The core security world secrets are protected by Administrator Cards
 written by the initialization software and kept safe by the user.
 Application keys can either be made available to any nCipher module
 appropriately programmed with the user's Administrator Cards (module
 protected keys) or they can be protected by further smart cards known as
 Operator Cards that provide an additional layer of security.
 2. The nCipher CSP
 If the CSP is set up to use module-protected keys, when applications
 tell the CSP to create a key, it needs no input from the user. If the
 CSP is set up to use Operator Cards and is told to create a key, it
 first looks to see if there are any cards which it can load
 automatically, and uses those if any are present. If not, it prompts
 the user to choose which Operator Card Set to use.
 1. Cause
 The Install Wizard for the nCipher CSP support software on Windows 2000
 offers a check box for controlling whether a key to be generated is
 module protected or to be additionally protected by an Operator Card
 When the Install Wizard is used to create an Operator Card Set then the
 nCipher CSP key generation behaves as requested by the user.
 If cardset protection is selected from the Install Wizard but a new
 Operator Card Set is *not* created, the wizard incorrectly sets the
 nCipher CSPs up to use module protection for all keys that they
 subsequently create.
 2. Impact
 If the user is affected by this issue, any application key generated
 by the nCipher CSP will be incorrectly protected by the module alone,
 rather than by a combination of operator card set and module.
 This means that an attacker, who gains control of any nCipher module,
 has been programmed into the key's security world can gain unauthorized
 access to this key, since no further smart card authorization is
 3. Who May Be Affected
 This problem only affects keys that have been generated by the nCipher
 CSP after the Install Wizard from CD version 5.50 has been run.
 The problem does not affect keys that were
 * generated by any software other than the nCipher CSP, or
 * generated by the nCipher CSP using the Install Wizard from any CD
 other than version 5.50.
 4. How To Tell If You Are Affected
 To find out whether you're affected, run 'c:\nfast\bin\csputils.exe -d'
 from the command line. This will give you a detailed summary of all your
 containers and information for the keys they contain.
 Each key (key exchange and/or signature) will have a description
 including whether or not it was generated by the nCipher CSP, its hash,
 and its protection method.
 A cardset protected key (here stored in a container called 'expimptst')
 will have an entry like the following (lines have been truncated for
 Detailed report for container ID _TAG_...
 Filename: key_mscapi_container-cbfb7b11909b40ddc50da759d6...

 Key was generated by the CSP
 Key hash: 6fa4c59efefb6c01db6eca9f1eadbb17158fc2a8
 Key is recoverable.
 Key is module protected.
 If you have keys unexpectedly module protected when they should be
 cardset protected you are affected by this bug.
 1. Users who have NOT already created a key with the wrong protection
 In order to force MSCAPI applications to generate cardset protected keys
 a file 'wizardfix.reg' should be created containing the following text:
 Windows Registry Editor Version 5.00
 This file can then be run by the user to change the appropriate registry
 entry that determines the behavior of key generation using the nCipher
 Alternatively, the user can edit the registry value specified above
 directly using 'regedit'.
 The registry setting must be reset using either of the above methods
 after each invocation of the affected nCipher CSP Install Wizard.
 2. Users who have already created a key which is erroneously module
 Users who have already generated keys which were intended to be cardset
 protected, but due to this error are not, are advised to apply the above
 registry fix and generate new keys. nCipher recommends against
 converting existing module-protected keys to cardset-protected status,
 since it is extremely difficult to do this in a way that increases

Trade Federation Console
The Trade Federation Console is an optional component that allows you to inspect the state of Trade Federation and what it sees, from the device states to the current tests in progress.
It is a great tool for monitoring a large number of tests running in parallel and understanding the progress of each test.
Reaching the console
Once Tradefed is built, the launcher script is accessible from your path and by default will take you to the console.
The console presents itself with the tf > prompt.
What can the console do?
The help of the console will always list the most up-to-date information. A few interesting features of it are:
 - List the devices and how Tradefed sees their state: list devices
 - List the currently running invocations and their metadata: list invocations
 - Get the logs of all running invocations and Tradefed: dump logs
The console allows you to debug what is happening in Tradefed and the devices by querying some states that are not shown together anywhere else.
How to avoid the console?
In several cases the console is not needed, or example When running a one-time command.
In such cases, commandAndExit can be added to the launcher script command in order to prevent the console from starting. This extra argument is needed when attempting to run Tradefed as part of a script or piping its output directly. Letting the console enabled while running Tradefed from a script will triggered an inconsistent behavior and might cause several issues. run commandAndExit
Console autocompletion
The console provides basic autocompletion of configuration names.
tf > run
result in:
Display all 167 possibilities? (y or n)
By hitting TAB after the run you can get the full list of configurations available. And if you have a partial name already typed in, the console will print all the possibilities.
tf >run tf/
tf/acceptance tf/fake tf/func
tf/stress tf/uiautomator tf/unit-runner
tf >run tf/
This is a useful when you don't remember an exact configuration name.

Fast Ball Physics
Is there away to calculate the speed of my sons pitch with
a stop watch? He throws from 60 feet 6 inches.
Not likely unless you have a fast finger! Let's say your son throws a 60
mph fastball -- that's equal to
88 ft/sec. Since the distance from mound to plate is 60.5 ft, that is a
lapsed time of ~0.7 sec. It is estimated that humans have a reaction time
of ~0.1 sec., so the measurement would not be very accurate.

Dry Round Hay Bale Storage Costs
Focus on ForageWisconsin Team Forage
Dry Round Hay Bale Storage Costs
by Brian Holmes
PDF Version
Round bale storage economics depends on a variety of issues. Investments in structures need a longer time to yield beneficial returns, while low capital systems can be used for a short period before they pay off. If a person will be in the hay storage business for 15-20 years, a building may be a good choice. If a person will be in the hay storage business for only 1-5 years, a building may not be a good choice. The type of hay storage to use is influenced by how long the hay will be stored each year and in what seasons. Dry matter (DM) loss of dry hay bales is a function of hay moisture, temperature, and how long the hay is exposed to those conditions. The higher the moisture and temperature, the higher will be the rate of decomposition. Large losses can occur in a short period under moist hay conditions (>30% moisture) when the temperature is high (>70°F). Even at a low rate of decomposition, a large quantity of hay can be lost over a long storage period.
What factors influence dry matter loss in stored bales?
Storing hay inside a building results in minimal DM losses of 1- 5%. Hay should be stored so as to reduce the exposure to moisture. Bales will absorb moisture from the soil if left outside on the ground yielding the highest DM losses (DM loss = 5-20% up to 9 mo. storage and 15-50% DM loss for 12-18 mo. storage). Even when covered by plastic tarps, contact with moist soil increases the DM loss compared to bales not in contact with the soil (DM loss = 5-10% up to 9 mo. storage and 10-15% DM loss for 12-18 mo. storage). Higher density bales tend to have lower loss values in the DM loss ranges listed above. Lower density bales will have higher losses in these ranges as they tend to absorb more moisture than higher density bales. Elevating the bales above the soil breaks the wicking action of moisture from the soil. This practice can reduce DM losses by an additional 2-15%. Uncovered round bales touching on the sides will hold water as it runs off and is directed into the bales. The worst case of DM loss occurs when low density bales rest on the ground, are not protected from precipitation, and are stored for a long period of time in a wet warm climate. Round bales shed water better than square bales which should not be stored outside without a cover. Small bales tend to have a have a large surface-to-volume ratio. Since outside storage exposes surfaces to high loss rates, large bales will have a lower DM loss than smaller bales.
Densely packed bales shed more moisture than low density bales. If bales must be stored outside, use high density baling methods. Large bales are more susceptible to initial harvest moisture than are smaller bales because they retain moisture longer in storage. Dry the hay below 17% moisture before making large bales. Net wrapping helps bales shed precipitation better than those wrapped with twine. Flat hay blades like grass or sorghum will shed water better than coarse hay like alfalfa.
A climate with high precipitation, relative humidity, and temperature has higher moisture hay and higher losses than one that is drier and/or cooler. Placing bales in the sunshine helps to keep them drier than if they are stored in the shade while outside. Locate outside storages at higher elevations, not in low lying areas toward which runoff drains.
There are a variety of ways to keep bales dry when being stored in humid climates. Direct precipitation can be kept from the hay by placing the bales under roof, wrapping them in plastic or in net wrap, or placing the bales under a tarp. Moisture can be kept from wicking from the ground to the hay by separating the hay from the soil. Use plastic wrap, large crushed stone, ties and/or poles, pallets, or tires to keep the hay off the ground.
Placing a value on storage loss
The value of hay depends on what a willing buyer and a willing seller can agree upon. If you have to buy hay today, what would you give for it? If you wanted to sell hay today, what would you need to get for it?
Screen Shot 2016-07-15 at 10.49.24 AMFeeding value (grass hay vs. alfalfa hay) influences the price as does handling and feeding convenience. Depending on the animals being fed and the other ingredients in their ration, the producer buying hay will be looking for a specific type and quality of forage. Large round bales tend to be discounted from square bales over the range of all feed values.
Table 1 shows the hay value lost as a function of DM loss during storage and the original hay value. For example, hay worth $60/Ton and losing 15%, the value lost is $9/Ton of hay
originally present.Screen Shot 2016-07-15 at 10.49.01 AM
What's the economic return from various round bale storage systems?
There are low to high capital cost alternatives for large round bale storage. The low capital cost systems often have high DM loss costs. One should consider both the initial captal investment as well as the annual cost which can include depreciation, interest, repairs, taxes and insurance on the capital investment as well as labor, equipment, fuel, plastic and DM lost.
The question then becomes, what can I afford to spend to prevent the loss of feed while storing large round hay bales? To answer that question, a spreadsheet was developed to do the calculations used for the cost analysis. The assumptions highly influence the results of the capital and annual costs of the various alternatives. One significant factor is the DM loss used for each alternative storage system. The results and conclusions are based on the assumptions used. Using different assumptions can result in different results and conclusions. For your situation, you should use the spreadsheet to enter your own assumptions. The Excel spreadsheet can be downloaded from the UW Extension TEAM FORAGE, Harvest and Storage web site at the URL
Screen Shot 2016-07-15 at 10.49.36 AMAn example analysis presented below is based on typical DM losses for various storage alternatives used in a humid climate using plastic twine on tightly wrapped bales (Table 2). Use of sisal twine and/or loosely wrapped bales will experience higher losses of DM for bales exposed to the ground and precipitation. Location in a wet climate will experience higher losses while location in a dry climate will experience lower losses than those used here.
Dry Climate = Western U.S.
Humid Climate = North Central to Northeast U.S.
Wet Climate = South Central to Southeast U.S., Northwest U.S.
Note the same 2% loss for a building with hay stored for 6 or 12 months. This means the annual cost for each system will be the same.
Screen Shot 2016-07-15 at 10.49.58 AMBuilding costs are a function of size and construction type. For this analysis, a builder was asked (in late 2003) to provide the cost of a hay storage shed without walls. The cost for a 30×40 ($8.45/sq ft for 12-ft walls, $9.12/sq ft for 14-ft walls) and the cost for a 40×90 ($5.56/sq ft for 12-ft walls, $5.81/sq ft for 14-ft walls) were provided. This cost was for the building shell only. Site preparation and floor would cost extra. For this analysis, a 16-ft tall building worked best for stacking the bales of Table 3 three high. Consequently, a cost of $6.00/sq ft was used. Recent cost increases for steel and lumber may make these values obsolete.
For this analysis, the assumptions for the hay stored and the building used for storing the bales are listed in Table 3. The bales are assumed to be stored three high in a long axis horizontal position with 8 rows on the bottom layer and 6 rows on the top.
Screen Shot 2016-07-15 at 10.50.08 AMAn alternative storage is a pad constructed of crushed stone known as macadam, Table 4. This material allows water to drain away from the bales and not wick up into the bales. This helps to keep the bottom of the bale drier and reduces loss compared to resting on soil. A pad only large enough to support the bales was used. In the analysis, a macadam surface was used alone or in combination with pallets. When combined, the macadam is probably needed to provide a good driving surface for the equipment used to load and unload bales. There is only a slight improvement in DM recovery (from reduced deterioration) when both pallets and macadam are used together. Thus it may be difficult to justify both if a drivable surface can be maintained without macadam.
Pallets are sometimes used to elevate the bales above the ground. The cost of recycled pallets was used in the analysis.
Results of Analysis
Screen Shot 2016-07-15 at 10.50.22 AMThe crushed rock pad with tarp covering is the most cost effective system for 6-month storage (Figure 1). In the case of 6-month storage, storing the hay on the ground is quite similar to that of storing

I intend to plot x-y coordinates of a traced object with scatterplot.density to use colour to show the density of points in the scatterplot instead of just displaying the points in a smooth scatterplot (smoothScatter). When I run the following short segment of the trace:
x <- c(69.8, 69.8, 70.07, 70.87, 70.87,72.48,73.02, 73.02, 74.36, 74.63)

par(mfrow = c(1, 1))
scatterplot.density(x, y)
I get the following error:
Error in image.default(x = 1, y = z, z = matrix(z, nrow = 1, ncol = length(col)), : increasing 'x' and 'y' values expected
I can blot the points in a smoothScatter without a problem, but this would not help once I add the full trace with 1500 x-y coordinates.
Any suggestions and help with the scatterplot.density problem would be highly appreciated! Thanks!

What I've found is that if the argument num.bins is high enough to seperate each point into a single bin then you will recieve the error. Try
scatterplot.density(x, y, num.bins=11)
scatterplot.density(x, y, num.bins=10)
the default is 64. That means 64 bins in the x axis and y axis. You either need to be lower you're bin number, add more points, or be content with the error. Hope that helps.

Thank you! That solved the problem. Also after including all other data points, it became obvious that 64 bins would be too detailed for the trace anyway. – user2510541 Jun 22 '13 at 0:33

text: Our impact Past successes Journey to Hospital Land A therapeutic program for children in hospital In conjunction with Hadassah Hospital's Director of Paediatric Education and Therapy Services (Edna Pinchower) and the Chairman of Department of Paediatrics (Prof Eitan Kerem), the Journey to Hospital Land program has been developed by Melbourne based award-winning author and child and adult psychologist, Esther Takac. It is designed for the Israeli hospital system, which provides a unique cross cultural environment where religious Jews, secular Jews, Muslim and Christian Israeli Arabs and Palestinians spend time together. This provides a real window of opportunity for getting to know 'the other' and reducing fear, mistrust and stereotypes. The program has three components… 1. 'Yoni's journey to Hospital Land' A therapeutic storybook which helps children manage the hospital experience (including pain management, relaxation breathing and cognitive behaviour therapy strategies tailored for children). 2. 'Parents' Guide to Hospital Land' Providing ideas for parents to support their child through the hospitalisation experience. 3. A Hospital Land website A place for children to share experiences and gather ideas. 'Yoni's journey to Hospital Land' - EXCERPT FROM 'TRAVEL GUIDE' Going to hospital can be strange and a bit scary. Everything is so different! The doctors with their stethoscopes, the machines that beep, the other kids in bandages, the noises and lights when you're trying to sleep, the food, the people you meet, even the strange medical language the doctors and nurses speak! It's all so different it's rather like being in a different land – you could call it Hospital Land! When people travel to a foreign land they often take a travel guide to help them find their way. It tells you what to expect and how to behave. So this book is a travel guide to Hospital Land – helping you find your way in hospital and know what to expect. It tells you what happens when you first come into hospital, what the nurses and doctors do and what it's like sharing a room with somebody you don't know. And just like travel guides have traveller's tips and a little dictionary so you can manage with the different customs and language, so this book also has tips. They can help you manage in hospital, such as how to go to sleep when it's noisy and what to do if you're nervous about blood tests. There's also a little dictionary so you can understand some of that foreign medical language. All travellers set out on their journey not knowing exactly where it will lead them. Sometimes its only when we journey away from the things we know that we learn new things about the world, and ourselves. I wonder what you will learn in your journey to hospital land! 'Parents' Guide to Hospital Land' - EXCERPT FROM 'MEETING THE OTHER' In hospital you and your child will meet people from different cultural backgrounds. They may be people you would never meet or talk to in your normal life. In fact, you may find yourselves in very close contact with these "other" people. If they are fellow patients, you may be sharing a room, using the same bathroom or kitchen. This culturally different person may also be looking after you in the hospital – a doctor, nurse or teacher. It can feel awkward and uncomfortable at first. However, you are likely to see that here in hospital the usual separations between people are less relevant. Here the divisions are between the sick and the healthy. And the healthy, no matter what background they come from, are all working together to help the sick. In this world of sickness and health, where we are all made of the same flesh and blood, different relationships develop. The program is now almost ready. It will be distributed to children and their parents in paediatric departments at Hadassah and a range of other children's hospitals across Israel. Esther's work on research, development and writing the story and parents' guide, and the illustrator's work have been contributed on an honorary basis. Financial contributions have been made by Hadassah hospital and donors in Israel. However additional donations are required for creating the website, and printing Yoni's Journey to Hospital Land Storybook and Parents' Guide.


text: I Am Not Inarticulate is a documentary project that seeks to shed light on a community of beings that are often misunderstood and misheard. Unable to excel or even participate in the most necessary of human traits, their shared disability of stuttering places them in a stagnant position. Though the knowledge of communication exists and has potential, it is disclosed in fragments that leaves the result in a state of alteration. All with varying degrees of stuttering, they all exist as constructions of how their struggle has shaped and identified them, in terms of how they view themselves and how others perceive them. Constricted by their limitations, many of them experience moments in time where all control is lost. Their interest in participating as a member of a stuttering association comes as a result of this loss of control, with a desire to take it back. This body of work utilizes the stillness and silence of the photographic medium in an attempt to display the banality of the issue based on what can only be seen, allowing the viewer to make assumptions and connections based on thematic context.

Traumatic and Complicated Grief Among Children: One or Two Constructs?
The purpose of this study was to examine the concepts of traumatic and complicated grief among children. Some authors seemingly use the concepts interchangeably, whereas others make a distinction between the two. A sample of 240 mainly parentally bereaved children were administered the Extended Grief Inventory (EGI). Two confirmatory factor analyses were run to examine the EGI factor structure and to determine whether traumatic and complicated grief are one or two concepts. Goodness-of-fit tests for the two models was considered acceptable for both models, however, the two-factor model was a better fit. Multiple regression analyses found that children's age, gender, and ethnicity were important predictors of traumatic grief but only gender was a predictor of complicated grief. Violent death was a predictor of complicated grief in an unadjusted regression analysis.

This paper discusses the dynamics of the current security and defence landscape (SDL), viewed from within the framework of the rules-based international order (RBIO), with particular focus given to the terrorism phenomenon. To better understand the undercurrents of the international SDL, demands consideration of the perspectives of other geopolitical actors, specifically, the Russian, the Islamic, and the Chinese. What is clear is that the dominance of the Western geopolitical polar is constantly challenged by the aforementioned geopolitical polars – who also understand that the legitimacy of any action is determined, rightly or wrongly, by the Western Order. The current SDL is thus animated by Russian, the Islamic and the Chinese challenges, even threats, against the a RBIO defined, institutionalised, and controlled by the West. What emerges is a multi-polar SDL, configured by multi-linear vectors between the West and other competing geopolitical polars; each seeking to divert power currents toward their direction. The tensors and trajectories between the competing power vectors are defined much by the ebbs and flows of the polars' geopolitical capabilities (political, economic and military) relative to each other.

If a life insurance company is delaying payment of your claim, you may be owed interest.
When an insurance company denies or delays your claim, they can continue investing the proceeds and accruing interest that would otherwise be in your pocket. The insurer may owe you that interest under certain circumstances.
To find out if you are entitled to interest on your delayed life insurance payout, contact our life insurance beneficiary lawyers. We have over 25 years of experience getting clients paid and getting clients interest on their delayed payout. We can tell you if you are owed interest during your free, no-obligation case evaluation.
How Long Does it Take to Receive Life Insurance Death Benefits, Usually?
Wondering how long insurance companies take to process claims, or how long does it take for a life insurance company to pay out? An uncontested claim for death benefits, where the death of the insured does not require investigation, is usually paid within 30 days. Most states require life insurance companies to respond to a claim within thirty days, whether that response is approval, denial, or a request for more information.
Insurance companies are required to tell claimants which of the reasons life insurance won't pay out. And when life insurance does not pay promptly, you have a right to know why.
How Can a Beneficiary Get Interest on a Delayed Life Insurance Payout?
If an insurance company unreasonably delays its response to your claim for death benefits, you may be entitled to interest. Whether you are owed interest on life insurance death benefits depends upon the terms of the policy and the jurisdiction governing the policy.
Some life insurance policies include a provision that entitles a beneficiary to interest after a specified delay in payout.
Many states have enacted statutes that grant interest to a beneficiary of a life insurance policy when an insurer unreasonably delays a claim determination. For example, this Iowa statute explains the circumstances that allow a beneficiary to collect interest and the rate at which the interest is calculated.
Some delays in payment of the death benefit are considered inherently unreasonable, including:
Delay in Life Insurance Payment after Claim has Been Approved
Occasionally, an insurer or a company's agent will tell a beneficiary that a claim has been approved, but the insurer delays sending payment. The longer an insurer retains the funds, the longer an insurer is able to continue investing those proceeds and reaping the profits for its shareholders. Under these circumstances, a beneficiary may be entitled to interest.
Delay in Payment of Claim Because Life Insurance Company Does not Contact the Beneficiary
Frequently an insurance company has reason to know that an insured died but fails to reach out to the beneficiary of the life insurance policy. Often a beneficiary is unaware that they are named in a policy or that a life insurance policy even exists.
If an insurer has reason to know that an insured has died, for example, because they use the Social Security Death Master File to identify policyholders who have died, that insurer should notify the beneficiary promptly.
Recently, several states have brought lawsuits against insurance companies that knew of policyholder deaths but failed to notify beneficiaries, retaining the death benefits and the interest accruing on them instead. Under these circumstances, a beneficiary may be entitled to interest due to the unreasonable delay.
Why Would a Life Insurance Payout Be Delayed?
Payout may be delayed six to twelve months or longer if the insurance company must investigate because:
If you are a beneficiary to a life insurance policy and you've submitted your claim and all required paperwork but haven't been paid, know that the insurance company has no incentive to pay you quickly. In fact, any delay means your payout is accruing interest and benefitting the insurance company's shareholders.
In the past there were many examples of life insurance companies not paying claims without delay. Fortunately, laws have been enacted to incentivize insurers to pay life insurance claims promptly, and if they do not, they may have to pay you interest.
How Long Does a Life Insurance Investigation Take?
What is the typical timeline for insurance companies to investigate claims? It varies, depending upon the circumstances of the death. Beneficiaries should be sure to respond promptly to all information and documentation requests from the life insurance company.
After the insured has died, beneficiaries of the life insurance policy file a claim with the insurance company and include a copy of the death certificate with their claim, keeping at least one original death certificate for their records in the event that the life insurance company misplaces the one sent to them.
When the insurance company receives the claim form and a certified copy of the death certificate, insurers have 30 days to deny the claim, pay the claim, or ask for more information.
In some situations, insurers will need to investigate a claim and the payout will exceed 30 days. Depending on the terms of the insurance policy and the laws that govern the policy, sometimes a beneficiary will be entitled to interest that has accrued during the delay of payment.
If your claim has been pending for more than thirty days, whether you have heard from the life insurance company or not, contact our experienced life insurance beneficiary attorneys. We help beneficiaries nationwide get paid with interest when their claim has been unreasonably delayed.
When Will Life Insurance Companies Investigate Claims?
In most cases, an insurer will either deny a claim or pay a claim within 30 days. When there is a delay in life insurance payout instead of denying or approving, it may mean that an insurer requires more time to investigate the claim. Delays will likely occur in the following situations:
Delay in Life Insurance Payout When the Insured Died by Homicide.
When an insured is murdered, the insurance company often waits to pay any benefits until the investigation is completed. Depending on the type of policy in question (term life, whole life, or AD&D insurance), the insurance company may need to know whether the beneficiary is associated with the murder or whether the insured was engaged in a felony at the time of his or her death
Delay in Life Insurance Payout When the Insured Died in a Foreign Country.
If the insured dies while abroad, an insurance company may take longer to investigate the circumstances of the death.
Insurers always require proof of death when a claim is made. In the U.S., a death certificate is acceptable proof of death. However, customary practices, records, and technologies vary across countries and continents, and a foreign death certificate may not satisfy the insurance company. Also, to ensure a claim for overseas death is not fraudulent, an insurance company may attempt to confirm the circumstances of the insured's death independently. Depending on where the insured died, this may extend the investigation period significantly.
Delay in Life Insurance Payout When there is a Beneficiary Dispute.
If the insurance company is notified that multiple parties might have a claim to life insurance proceeds, it will postpone paying the benefit until a rightful beneficiary is established. Often, the insurance company will not make this determination itself. The insurer may file a life insurance interpleader action, and a court will decide the lawful beneficiary.
Case Study #1: the insurance company delayed paying for over two years because the insured had a girlfriend and child and neither was named in his policy. Luckily for our client, Illinois law prevents such improper claim practices and unreasonable or vexatious delay in paying claims, and we were able to get our client paid.
Delay in Life Insurance Payout When the Insured Died Within the Contestability Period.
The contestability period lasts for two years. During this time, an insurer is authorized to investigate to look for evidence of fraud and misrepresentation in life insurance application and medical questionnaire. If the insured dies within this two-year period, a payout of benefits may be delayed while the insurer examines medical records, financial records, or other relevant evidence.
Delay in Life Insurance Payout When the Insurance Company Makes an Administrative Error.
Case Study #2: payment of our client's claim for death benefits was delayed because the insurance company never received medical records from a doctor that the insured never visited.
If your claim is denied, please get all the details you can about the reason for the denial: it may be something as simple as a mistake such as this preventing you from getting your life insurance payout.
Delay in Life Insurance Payout When the Insured Never Received Notice of Lapse or Termination.
Case Study #3: Our client's claim was denied because the policy lapsed and terminated due to non-payment of premiums. We investigated and found that the insured never received the statutorily-required notices. We got our client paid.
What Can a Lawyer Do if a Life Insurance Payout is Delayed?
An experienced life insurance lawyer will be able to tell you whether the delay can be turned into approval and whether you are entitled to interest for the time of the delay. Do not rely on an insurance company to tell you that you are entitled to interest – they have no incentive to do so.
Our life insurance attorneys can demand and obtain the full death benefits you are legally entitled to. Again, your right to interest depends on the jurisdiction in which the policy was issued and the terms of the policy itself, and we help beneficiaries get paid in jurisdictions across the nation.
For more information about your rights to interest on a delayed payout of benefits, contact a trusted life insurance attorney at the Boonswang Law Firm with your questions. Your initial case evaluation is free of charge, and if we take your case, know that we don't get paid unless you do.

NeuroCa: Integrated framework for systematic analysis of spatio-temporal neuronal activity patterns from large-scale optical recording data
Minjee Jang and Yoonkey Nam
In this work, Minjee developed a MATLAB-based toolbox, named NeuroCa, for the automated processing and quantitative analysis of large-scale calcium imaging data. This tool includes several computational algorithms to extract the calcium spike trains of individual neurons from the calcium imaging data in an automatic fashion. Two algorithms were developed to decompose the imaging data into the activity of individual cells and subsequently detect calcium spikes from each neuronal signal. Applying our method to dense networks in dissociated cultures, we were able to obtain the calcium spike trains of ∼1000 neurons in a few minutes. Further analyses using these data permitted the quantification of neuronal responses to chemical stimuli as well as functional mapping of spatiotemporal patterns in neuronal firing within the spontaneous, synchronous activity of a large network. These results demonstrate that our method not only automates time-consuming, labor-intensive tasks in the analysis of neural data obtained using optical recording techniques but also provides a systematic way to visualize and quantify the collective dynamics of a network in terms of its cellular elements.

6 Must-Have Power Tools for the Serious Home Renovator
Whether it's converting an attic into a complete bedroom or installing new cabinets in the kitchen, home renovation projects are hard work. You must measure walls and corners, install fasteners, make adjustments and more. And if you make a mistake, you might be forced to start over. The right power tools, however, can streamline your renovation projects, allowing you to quickly and efficiently upgrade your home.
1. Cordless Drill
A cordless drill is an invaluable tool for serious home renovators. Typically featuring either a nickel-cadmium or lithium-ion rechargeable battery, their primary function is to bore pilot holes into wood and other materials. Most cordless drills support a variety of bits, so you can use them to insert screws into newly created pilot holes as well. Just remember to keep your cordless drill charged or invest in a backup battery.
2. Cordless Screwdriver
Many home renovators simply use a power drill to extract or insert screws. While this usually works, a cordless screwdriver is the preferred choice among serious renovators and builders because it performs fewer revolutions per minute. This makes them easier and more comfortable to use. Keep in mind that cordless screwdrivers aren't as powerful as cordless drills. Therefore, you shouldn't use them to drive screws into solid materials. Only use them to extract or insert screws.
3. Air Compressor
Some tools are designed to support the function of other tools. An air compressor, for example, is a versatile power tool that's used for pneumatic staple guns, nail guns, paint sprayers, water hoses and more. Without an air compressor, you won't be able to use any of these tools. Air compressors feature an electric or gasoline motor that compresses air to a specific pressure. While all air compressors perform this action, there are different available, including twin-stack, wheelbarrow and pan cake style.
4. Belt Sander
A belt sander will allow you to buff and refinish surfaces in your home renovation projects. This handheld, motorized power tool features two small cylinders on the bottom that hold sandpaper. When turned on, the sandpaper moves rapidly against any surface on which it's placed to remove the outer layer of material. After the outer layer has been removed, apply your surface preferred finish. You can use a belt sander to refinish floors, cabinets, doors and furniture. For most projects, it's recommended that you start with a high-grit sandpaper and gradually transition to a low-grit paper to achieve the smoothest finished texture.
5. Nail Gun
Also known as a nailer, a nail gun is a handheld power tool that drives nails into wood and other materials. Most nail guns are driven by compressed air though some use butane or other flammable gases. Regardless of type, all nail guns make driving nails into floors, walls and ceilings a breeze.
6. Circular Saw
A circular saw is a power tool that uses a circular, metallic disc to cut through material. Power supplied from either a connected electrical outlet or battery spin the metallic disc. When the spinning disc is placed against a surface, such as a 2-by-4, it creates a clean, smooth cut through the material. Without a circular saw or any other powered saw, you'll have to cut materials the old way: using a hacksaw. This is incredibly tedious and inefficient for home renovation projects, so add a circular saw to your toolbox.
For serious home renovators, a hammer and manual screwdriver isn't going to cut it. Invest in these power tools to streamline your renovation projects.

LBNL Report Number
We review the relationship between energy efficiency improvement measures and productivity in industry. We review over 70 industrial case studies from widely available published databases, followed by an analysis of the representation of productivity benefits in energy modeling. We propose a method to include productivity benefits in the economic assessment of the potential for energy efficiency improvement. The case-study review suggests that energy efficiency investments can provide a significant boost to overall productivity within industry. If this relationship holds, the description of energy-efficient technologies as opportunities for larger productivity improvements has significant implications for conventional economic assessments. The paper explores the implications this change in perspective on the evaluation of energy-efficient technologies for a study of the iron and steel industry in the US. This examination shows that including productivity benefits explicitly in the modeling parameters would double the cost-effective potential for energy efficiency improvement, compared to an analysis excluding those benefits. We provide suggestions for future research in this important area.


How it works - Basic
~ Single Pinhole ~
Fundamental Law: Light travels in a straight line
A candle emitting light behaves in this way:
Tracing out some of the light rays illustrates this point
Adding a light tight box blocks light from entering box
If we add a small hole at the center, some light can enter
We can trace light reflecting off of the rest of the candle in the same way
And form an image of the candle upsided down at the back of the box
If we now add film at the back of the box, a cap at the hole to control when light enters the box and exposes the light sensitive film, we have a camera.
That's it. This is a basic pinhole camera and all that is needed to make images.
The rest is refinement to a specific end.

Day of Mourning
Why is April 28th a Day of Mourning?
Every year on April 28, people across the country gather to light candles and wear ribbons as they pay their respects and remember the thousands of men and women who have been killed, injured, or suffered illness as a result of work-related incidents. We also honour the families, coworkers, and friends whose lives have been significantly impacted by these tragedies. April 28th was chosen to reflect the anniversary of the day Ontario passed the Workers' Compensation Act in 1914.
How do unions improve workplace health and safety?
Unions stand up for the health and safety of everyone who works for a living. We work with employers to improve working conditions. Unions work with governments to improve workplace health and safety standards and pass laws to punish employers who put lives at risk for their own gain. We can't bring back those who have died, but we are working hard to make workplaces safer for today. By working together – with employers, unions, workers, and our health and safety partners, we can work towards every worker returning home at the end of the day safe and sound.
UFCW Canada encourages every worker to make workplace health and safety a personal priority and help spread the word that workers have the right to refuse unsafe work.
On April 28, let us remember those who have been injured or killed on the job, and keep them in our thoughts. Let us honour the memory of those killed or injured on the job, and never forget the importance of our commitment to keep workers safe.
To commemorate the National Day of Mourning, UFCW Canada has developed a Day of Mourning poster available for download in both English and French. See below the article image for different formats.

:1→J :For(I,2,dim(L₁ :If L₁(I)=L₁(J:Then :.002+L₁(J→L₁(J :Else :If L₁(I)=int(L₁(J:Then :.001+L₁(J→L₁(J :Else :J+1→J :L₁(I→L₁(J :End:End:End :J→dim(L₁
Run-length encoding (RLE) is a very easy compression algorithm that you can use for compressing a list of numbers. The way it works is that you remove all of the consecutive repeated numbers from the list, and modify the first instance of the numbers with how many repeated numbers there were.
For example, say you have a list of numbers 1,2,2,3,3,3,4. You start with the 1, and since there is only one 1, it wouldn't be modified. There are two 2's, however, so you would remove the second two, and add a decimal part (using fPart() of how many 2's there were (in this case, just two, which we represent as.002). You would do this for the rest of the list, and the final list would be 1,2.002,3.003,4.
To save memory (which is of course the reason we're compressing) we will store the result to L₁, the same list the uncompressed data is in. Throughout the loop, J is the index of the last element of the compressed part of the list, and I is the index in the uncompressed part. We don't have to worry about the indices colliding, since I is always bigger than J.
We loop over the list with I, and check if the current element has the same value as the last element of the compressed list. If it is, then it's the beginning of a run, so we add.002 to that last element.
If it isn't there's another possibility — the last element could represent an existing run of the same element. We check for this with the code If L₁(I)=int(L₁(J)). If this turns out to be the case, we add.001 to increase the length of the run. Otherwise, the element really is different, and we increase J and add a new element.
At the end, we store J to the size of L₁. This gets rid of all the unnecessary data, leaving us only with the compressed portion of the list.
Note that we never store anything to L₁ itself, only to its elements. This is a useful technique to avoid using too much memory while the program is running: if we stored to L₁, a copy of the list would be stored to Ans, which could easily give a ERR:MEMORY if the list is too large. As the program is now, the only additional memory used is contained in three real variables (I, J, and Ans).

syntax. Otherwise the defmethods won't work right. CLtL2 gives an example of using DEFTYPE in this way to define a "square 2-d array" type:
(defun equidimensional (a)
 (or (< (array-rank a) 2)
(deftype square-matrix (&optional type size)
 "SQUARE-MATRIX includes all square 2-d arrays."
 (satisfies equidimensional)))
So we can say something like:
(deftype *matrix-like* (&optional type nrows ncols)
 '(and matrix-like (satisfies (or (= (* (nrows A) (ncols A)) 0)
 (typep (mref A 0 0) type)))))
and then make the defmethods specify (*matrix-like* double-float) or whatever type as the types of the matrix arguments. Note that zero-element matrices and matrix views have any data type you want, and we don't evaluate (mref A 0 0) unless we know that there is at least one element in the matrix (view). Note that we don't ask for (array-element-type (my-array A)) because (a.) zero-element Lisp arrays may be tricky (I'm not sure), and (b.) we might use a C array instead of a Lisp array.
Code generation
The BLAS and LAPACK support four different datatypes: single-float, double-float, (complex single-float) and (complex double-float). We can generate DEFMETHODs for all different types of matrices by using the same "method template" that we use for WITH-COPIES. It's easy to find the right BLAS / LAPACK routine for a given datatype because it begins with a letter corresponding to the datatype: S for single-float, D for double-float, C for (complex single-float) and Z for (complex double-float). I've written some code sketches for this.
The BLAS and LAPACK wrapper functions that we support are put into an alist mapping from method name to method template. We could even store them in a file, though this could be a security risk if people mess with the file, no?
Dependency analysis (for a "smart Matlab compiler")
Here follows discussion of a "smart Matlab compilation" technique that tries to preserve Matlab copy semantics while avoiding copying whenever possible.
Types of accesses:
 1. overwrite-read: qr (A)
 2. overwrite-write: A(2:4, 2:4) = [0 1; 2 3];
 3. read: print (A(:, 2:3));
We can classify datapath links as follows. A (plain) read can be followed by anything.
 1. overwrite-read -> overwrite-read:
 [Q, R] = qr (A);
 [L, U] = lu (A);
 This requires saving a copy of the dependent variable the first time.
 2. overwrite-read -> overwrite-write: [Q, R] = qr (A); A(2:4, 2:4) = [0 1; 2 3]; These require saving a copy of the dependent variable, or at least a copy of the subview that is required. Of course if we are in a function and we don't have inter-procedural analysis, we have to return a whole copy of A.
 3. overwrite-read -> read:
 [Q, R] = qr (A);
 print (A);
 4. overwrite-write -> overwrite-read:
 [Q,R] = qr (A);
 E = eig (Q); (???)
 OK, no special handling needed.
 5. overwrite-write -> overwrite-write:
 [Q, R] = qr (A);
 [Q, S] = qr (B);
 Cleverness can avoid computing Q the first time (e.g. with a QR factorization, we can avoid computing Q explicitly or at all; with an eigenvalue decomposition, we can avoid computing the eigenvectors). Otherwise there's nothing we need to do.
 6. overwrite-write -> read:
 [Q, R] = qr (A);
 print (Q);
 OK, no special handling needed.
Dependency analysis is pretty easy in straight-line code. We may not know if we have a loop unless we macro-expand all the way and look for primitives (DO, GO, etc.). User-defined functions can be optimized if we ask the user to make assertions about inputs and outputs, or we can do inter-procedural analysis ourselves (operate on blocks -- find their inputs and outputs). For example, in Allegro CL v. 8.0 on MacOS X PPC:
CL-USER> (macroexpand '(dotimes (i n) (setf (aref A i) 0)))
(block nil
 (let ((#:g251 n) (i 0))
 (cond ((>= i #:g251) (return-from nil (progn))))
 (tagbody (setf (aref A i) 0))
 (psetq i (1+ i))
 (go #:Tag4))))
CL-USER> (macroexpand-1 '(dotimes (i n) (setf (aref A i) 0)))
(do ((#:g252 n) (i 0 (1+ i))) ((>= i #:g252)) (setf (aref A i) 0))
If we want to do this thoroughly, we'll have to trace out the control flow. User-defined functions may even have return-froms that make things messy. But eventually we have to make simplifying assumptions. These can be governed by a conservativity level so that the user can choose to sacrifice safety for speed.
"Matlab in Lisp"
Parse a Matlab file and convert it into a PROGN of Lisp statements. This can then be compiled (using the standard Lisp compiler) which gives you, therefore, compiled Matlab code! We can also use our own code optimization tools on the PROGN before we feed it into COMPILE.
It's too ambitious to try to replicate all of Matlab in Lisp, especially the GUI stuff and the toolboxes. Nevertheless, we can bring in a lot of useful functionality from e.g. the GSL (though that's GPL'd, be careful) or other libraries.

Product Parameters for Our MPP Electrical Conduit Pipe
Name: MPP Electrical Conduit Pipe
Product color: orange
Raw materials: PP powder is the main masterbatch.
Product length: generally 6 meters/piece, can be made into 6-13 meters/piece.
Product type: ordinary type and reinforced type, reinforced type is divided into excavation pipe and non-excavation pipe.
Connection method: use a welding machine to hot-melt butt joints, the fusion point is about 200 degrees, and cannot exceed 220 degrees. When the temperature reaches, the two ends can be butted. (Because the connection method of the MPP pipe is hot melt welding, the welding port is not good, it will damage the cable or may be flattened, so the MPP power pipe must be made of new material).
MPP material refers to a kind of modified polymer which is based on ordinary polypropylene resin (PP) and added with chemical raw materials and chemical auxiliaries with heat resistance, high pressure resistance and excellent insulation properties. Compared with ordinary PP material, MPP material has more impact resistance, oil resistance and chemical resistance, and also has excellent properties such as strong thermal stability and local heat resistance, which is suitable for the production of MPP power tubes.
MPP material, also known as modified polypropylene material (MPP material), is mainly used to produce MPP power cable pipes. Modified polypropylene pipes (MPP pipes, MPP power pipes) have the characteristics of high temperature resistance and external pressure resistance, and are suitable for 10KV The above high-voltage transmission line and cable pipes and pipes. MPP power cable pipe has good electrical insulation; it has high thermal deformation temperature and low temperature impact performance; MPP pipe has higher tensile and compressive properties than HDPE; in addition, MPP pipe is light, smooth, with low friction and can be hot-melted Welded butt; MPP pipe has excellent physical properties of corrosion resistance, long service life. MPP electrical conduits are made of modified polypropylene. The conduits can be laid without the requirements of excavation and destroying roads, which makes them can be applied to special constructions in roadway, railway, buildings and riverbed. Compared with traditional excavation construction, non-excavation construction is more environmental without the result of floating dust and traffic jam caused by construction. It is specially applied to constructions in historical sites, downtown, farms, highways and rivers which are hard to carry out excavation construction.
Identification of MPP Pipes and Non-MPP Pipes
In fact, it is not difficult to understand the properties of MPP and HDPE materials, and it is not difficult to identify MPP pipes and non-MPP pipes; MPP pipes have the characteristics of high temperature resistance, and the pipes are rigid, while HDPE double-wall corrugated pipes cannot withstand high temperature, and the material is thermoplastic; understand this essence After the distinction, it is very easy to identify without special testing equipment at the construction site. The pipe end can be sliced with the cutting machine attached to the pipe hot-melt butt machine. Because the MPP power pipe has the characteristics of high temperature resistance, it will not decompose during cutting. The cutting surface is smooth and flat; while the PE pipe cannot withstand high temperature, it will soften and decompose during cutting, and the cutting surface is rough. In addition, those who are familiar with the two kinds of pipes can also identify by tapping the pipes and the sound of the tapping. Due to the rigidity of the MPP pipe, the sound is clear and loud.
Advantages of Our MPP Electrical Conduit Pipe
1, Excellent electrical insulation property
2, Better in crush resistance and anti-tension than HDPE pipes
3, Higher distortion temperature and good performance in low-temperature impact
4, MPP conduits have light weight and smooth surface with small friction
5, MPP conduits can be connected by thermofussion welding and their service temperature range from -5℃ to 70℃
Application of Our MPP Electrical Conduit Pipe
1, Pipeline constructions in municipal construction, telecommunication, electric power, gas, water and heat supply
2, Urban and rural non-excavation directional drilling power pipeline construction and open excavation power pipeline construction
3, Urban and rural non-excavation directional drilling drainage pipeline construction and industrial sewage drainage construction
