text: Manganese (Mn) oxidation by the plant-pathogenic fungus Gaeumannomyces graminis var. tritici has been correlated with virulence in take-all disease. The mechanism of Mn oxidation has not, however, been investigated adequately. Research on bacteria and other fungi indicates that Mn oxidation is most often the result of the activity of multicopper oxidases. To determine if G. graminis var. tritici oxidizes Mn by similar means, the Mn oxidizing factor (MOF) produced by G. graminis var. tritici was characterized by cultural, spectrophotometric, and cellulose acetate electrophoresis methods. Based on our results, the MOF is an extracellular enzyme with an estimated molecular weight of 50 to 100 kDa. Electrophoresis and spectrophotometry indicate that the MOF is a multicopper oxidase with laccase activity.

The Classical Revival style of architecture is known as Jeffersonian Classicism because it is closely associated with the work of Thomas Jefferson (_PHONE_). The style is typified by simplicity, dignity, monumentality and purity of design, based on the use of Roman forms of classical antiquity, although later examples exhibit Greek influences. In the United States, the style emerged after the Revolution when the monumental architecture and republican ideals of Rome inspired the shape of American public buildings designed to house the newly organized state and national governments. Thomas Jefferson was one the most influential proponents of the style, designing buildings in early Washington D.C. and the University of Virginia at Charlottesville. Jefferson also set the stage for Early Classical Revival domestic architecture through the design of his homes in Monticello and Poplar Forest.
Classical Revival buildings may be one or two story tall, typically symmetrical in form and sometimes similar to a classical Temple, including the presence of a dome in public buildings. Residential Classical Revival architecture is typically two rooms deep with the long side commonly facing the street. Identifying features of the Classical Revival tradition include a gabled entrance portico dominating the front façade and usually equaling it in height, supported by four or more simple Roman Doric or Tuscan type columns. Smaller porches may be present on rear and side facades. In some examples, porches are recessed, also known as porticos. A semi-circular or elliptical fan light is usually present above a paneled front door. Examples of Classical revival domestic architecture with three and seven ranked facades are rare. A five ranked façade is most popularly observed.

Graphical representation
An impressive javascript library three.js is used for graphical representation of the orientation data. This library aims to provide 3D graphics in a browser. Most of the functionality was extracted to orientation.js module. It contains functions to initialize the drawing canvas (createCanvas), create objects (createCube), transformations to achieve rotation around world axes (setObjectQuaternion) and extracting device's orientation data (calculateEulerOrientationForDevice). The canvas is then attached to the DOM (the empty div in index.handlebars) mentioned earlier in indexController's handleWebSocketReceivedMessage function.
Calls to Device.update() function then dynamically update the rotation of the displayed object by using Orientation.setObjectQuaternion() function.
The maing WebGL and Three.js objects are
 - renderer - renders the scene using camera
 - camera - defines the view of the scene
 - scene - all displayed objects must be added to scene
Render is using a render function to update the canvas with the latest changes.
 var render = function () {
 renderer.render(scene, createCamera());
We are using a simple cube/box object which is instantiated using the THREE.BoxGeometry class. But it is not enough for displaying it in the scene. We have to specify the object material. We chose one of the simplest materials to display boxes with only one colour. For our demo purpose is the box a very nice representation of mobile device (mobile,phone,tablet). The selected colour is passed to the material constructor and our object can be appended to the scene.
 var scene = new THREE.Scene();
 renderer.setSize(600, 300);
 renderer.shadowMapEnabled = true;
 cube.receiveShadow = true;
 // add subtle blue ambient lighting
 var ambientLight = new THREE.AmbientLight(0x000044);
 // directional lighting
 var directionalLight = new THREE.DirectionalLight(0xffffff);
The 3d object is very nice but if we use only one color for all faces it doesn't look so good. The 3d objects becomes flat. Because of that we added 2 different lights to the scene with different colors and positions. It causes color changes on the faces which thank looks much more plastic. Unfortunately it slightly changes the resulting color so it is not so easy to identify the proper device.
In conclusion, notice what the template achieves. Play is not just a server providing resources on endpoints. It acts as a server and router for messages which can also apply transformations on them. It would also be possible to cooperate with other services and applications. All in a reactive way. Where else can Play and web sockets (or even different protocol) be used? How difficult would it be for example to create a 2d, isometric projection or even a 3d racing game using the Play server we already have? Wouldn't it be achievable by just changing the javascript front end? Or a message queue? Or an enterprise service bus?
We know that tests are very important part of the application. This is only a demo with only small amount of code but still we included at least tests for the util package in the play backend. Because only with tests you can build applications which can satisfy the Reactive manifesto.
Can we do better? There is always space for improvements.
 - Update the Play plugin for EmberJS to support the latest versions of JQuery and Bootstrap.
 - Detection if the browser supports required technologies eg. Orientation API and WebGL.
 - Better handling of WebSockets to ensure reliable connection and auto-reconnects.
 - Notification if the server is up and running.


about 50%. To avoid device damage, aeration temperatures should be less than 140º F.
Pulse continuously from vacuum to atmospheric (approximately) pressure and back. This helps sweep EO from the chamber. The rate of pulsing will be limited by equipment capability. No pulses have been reported at times less than 15 minutes, time from atmospheric pressure to vacuum back to atmospheric pressure.
Aerate longer at vacuum than at atmospheric or higher pressures. At vacuum there is little to no air or water molecules to block and slow the rate of EO degassing from the medical device.
Using less gas to sterilize reduces the amount of EO to be degassed. But it doesn't reduce total cycle time. Using 25% less EO to sterilize reduces aeration time about 5 to 10%--a savings of one hour in aeration. But, to use 25% less EO, we must increase exposure time by one hour. Using less EO results in a net trade-off of zero in reducing total cycle time, one hour more exposure offset by one hour less aeration.
We validate shorter aeration times, so we know we can reduce aeration time safely without leaving higher EO residues on the medical devices. The validation occurs in the following manner. First, measure the residue left after aeration, using the current long cycle. We measure residue on a hard-to-aerate material, PVC tubing. Although PVC is not generally in re-usable devices, medical device manufacturers have found it to be one of the toughest of all device materials to aerate. PVC tubing is placed in the chamber at the same locations we use barrier packs to measure efficacy. Second, measure residues on the PVC tubing using shorter aeration times. Third, if the residue left after short cycle aeration is no more than the residue left after the current aeration, we have demonstrated that the short cycle did not leave a higher residue and worked as well as the current cycle. Note: Residues are measured by an outside laboratory that specializes in such procedures.
Some service companies now offer short cycle upgrades. Upgrade costs range from $5,000 to $20,000. The hospital must validate these service company cycles. One firm is developing new control systems and seeking an FDA 510K so that they may offer them to any US hospital. The hospital would not have to validate a 510K cycle. These systems are expected to cost $15,000 to $20,000 installed. For either type of upgrade, the hospital can save 25% on gas cost, can double the number of cycles run each day, or can start the sterilizer late in the afternoon, knowing that sterilized devices will be ready for early morning surgery.
21st Century Blend--Steriflo® Sterilant Gas
Oxyfume 2002 and Penn Gas 2 blends use HCFCs which have 0.02+ Ozone Depletion Potential (ODP), a measure of a chemical's potential to deplete the stratospheric ozone that protects life on earth. The ODP is 2% of the ODP of 12-88 sterilant that was phased out in 1995. For this reason, under the Clean Air Act, hospitals may continue to use these materials in existing sterilizers until the year 2030 and may buy new sterilizers with these materials until the year 2015.
A new blend, with the brand name, Steriflo, has been developed. It has zero ODP and, under the Clean Air Act, may be used into the indefinite future with no expectation of a phase-out date. The new blend uses HFCs to control EO flammability.
The HFC blend offers other benefits over the current blends. It contains about 5% more ethylene oxide, so no matter what cycle the hospital uses, it can use about 5% less gas. In cycle studies with barrier packs, Steriflo sterilizes much faster than the current blends, meaning the operator can sterilize with less exposure time or in the same time with less gas, and Steriflo can be substituted in the same sterilizer with few equipment changes.
Steriflo provides the same benefits now available to the sterilizer operator. This sterilant gas offers:
 - Non-flammablity.
 - Highest available low-temperature SAL.
 - Compatibility with the most device and packaging materials.
 - Ability to sterilize most types of and largest size devices.
 - Usability in improved cycles.
 - Extended use of a sterilizing technology proven over the last 50 years.
Steriflo is now being validated in Europe and the US by medical device manufacturers and sterilizer makers. First conversions will begin in Canada and Europe. US use of the new blend will not start until it has been validated and is registered as a pesticide by the EPA. Expected date release for this product is 2001 to 2002.
Hospitals will continue to use EO sterilization because it sterilizes in a penetrating fashion. Hospitals will continue to use blend sterilizers because EO blend sterilizers have shown the good sterility assurance and high throughput. Improved cycles make the blend sterilizer both economic and flexible. The 21st Century Blend EO/HFC further enhances sterilizer performance while its zero ozone depleting properties make it a sterilant for the future. Most importantly, it is not subject to the 2030 phase-out date that affects the current blend sterilants.

TRUE OR FALSE: Cold weather is bad for batteries.
FALSE: Batteries like the cold. Lower average battery temperature means longer life expectancy. A typical baggage tractor battery weighs well over 3,000 pounds, which is too much mass to lower the internal temperature over the course of a day or two. Hopefully, the battery is being used and charged, which generates heat and maintains temperature. And even if the internal temperature drops, the electrolyte in a charged battery will not freeze. So in most cases, even freezing temperatures don't make any difference at all, and possibly they even help.
There is some bad news, however:
- Lower internal battery temperature means lower capacity: A cold battery could deliver as little as half the capacity of a warm battery. And probably at a time when the tractor is demanding more power to do the same work.
- Some chargers shut off before cold batteries reach 100 percent state-of-charge: In this case the electrolyte can stratify, leaving mostly water on top and create the possibility of freezing. Unlikely, but possible.
What To Do
Don't let a tractor sit on the ramp for days. Keep charging and discharging. And make sure you charge to 100 percent and equalize charge regularly to keep the electrolyte properly mixed.

When shelving international books, be aware that the direction of text along the spin varies from country to country—even those countries using Latin characters.
With English-language books, text goes from the top to the bottom. Italian books are reversed. Title text starts at the bottom and goes up.
Since my English books greatly outnumber my Italian ones, I flip the Italian ones upside down. This allows me to read all the titles on the spines in the same direction.

Comparison of CAD and manual sketching tools for teaching architectural design.
Automation in Construction, 19
978 - 987.
Official URL: _URL_
Communications for information synchronisation during the conceptual design phase usually require designers to employ more flexible and intuitive digital design tools. In developing such support tools, a case study research was initiated to first understand the current state of communication among novice design team members. The main purpose of the study is to understand the novice designers' collaboration culture when working on conceptual architectural design projects. The overall case study research involves 1) ethnography for data collection and 2) artefact and protocol analyses for data analysis. This paper presents the latter data analyses based on the earlier ethnography results about novice designers' conceptual design and technology design synthesis strategies. Data analyses on the characteristics of utilised external representation tools indicate that although conventional manual sketching is beneficial for providing rich intuitive design concepts, they have limitations when novice designers need to oversee complicated design problems. The study also found that although current conventional CAD tools are advantageous for detailed engineering design articulation, they do hinder novice designers' creativity due to their intuitive ideation limitation. Based on these results, this paper discusses the identified advantages and challenges of current design media and then proposes an alternative VR-based design interface for enhancing cognition and communication among designers during the conceptual design phase.

- Why didn't Ringo pat out the fire on the diary or do something?!
- Rule of Symbolism.
- And everything was on fire around her. If she tried rolling over, she would've gotten even more burns on her.
- Couldn't she have put the diary under herself and smothered the fire? The fire wasn't THAT close to her.
- And risking getting burned in vital places Not sure if I want.
- After reading all the references and theories one question remains: why penguins?
- Everything's Better with Penguins?
- Apparently it's a very obscure visual pun. If you read the Japanese word for "apple", "ringo" with Chinese conventions, it becomes "pingu", which is also why the penguins are called "pingu", rather than the more conventional "pingin". And the apple is ofcourse the most important symbol in the series — the apple cut in half is the eponymous "Penguindrum".
- It does relate to the plot as well if you think about it. Sanetoshi and Kenzan first met while on an arctic trip, and that is where they decided to form Pingroup. Likely, they made their symbol a penguin in reference to the way it began. Then the Princess of the Crystal took over Pingroup after they changed their name to Kiga Group. As for why she chose to continue the penguin theme we can't be sure, but at least it works thematically.
- So what purpose did Mario ultimately serve? The big revelation of him owning another penguin hat, and thus the other half of Momoka's soul ended up meaning exactly squat in the end.
- Wasn't Mario meant as a trigger for Masako to join the hunt for the Penguindrum, just like Himari triggered Shouma and Kanba to search for it? Episode 16 was pretty explicit about that; Masako agreed to hunt for it in order to save Mario's life.
- And to follow up from that, what was the Princess of the Crystal, in the end? We see that both Momoka and Himari are distict entities from her, and neither has a personality like her's, so what is she and why did she come into being from their union?
- Momoka's literal Split Personality Takeover?
- The Princess of the Crystal was one-half of the containers that sealed Momoka away, in the same way that the two bunnies/twins were the two halves of the container that sealed Sanetoshi. If the bunnies are any indication, the personalities of the containers are distinct from, but supportive of, those who they are sealing. As for why the penguin hat needs to be placed on someone's head for the Princess in the Crystal to take over, and the bunnies don't, though...
- I think the reason you need to wear the hat for it to work is because that is how someone would normally use a hat. There were several times where Sanetoshi was visibly feeding the two bunnies carrots or treating them as mere pets. This could be the reason the bunnies do not have the same restrictions as the Princess of the Crystal does, as they are functioning like any kind of pet bunny would.

Derived Types: PolygonB, PolygonN
An abstract class that serves as a base to its derived types, representing a collection of one or more exterior and interior rings..
The rings do not need to be connected to or
contained by other rings in the polygon. However,
all rings are considered to be part of a single polygon regardless of
their location. Rings can be embedded in the interior
of other rings. Embedded rings define interior
boundaries or holes within the polygon. Exterior
rings are oriented in a clockwise direction while interior rings are oriented
In general, you will work with the normalized polygon type PolygonN, whether creating a polygon or working with a polygon returned from a service request. See the discussion on binary and normalized geometry for more information. When constructing a PolygonN with overlapping rings in the same direction, the server will simplify the polygon for you. If two rings overlap, the overlapping area will be considered an interior ring (hole). If three rings overlap, the overlapping area will be considered an exterior ring and so on.


locations, and that is who I now believe is in the photograph with his wife, Laura Gertrude's mother.
So the man sitting on the chair in the photo above is William John Isaacs who was in the Wiltshire Constabulary from c1881 to 1907. This has been confirmed in a reply from the History Centre to PB: "William Isaac Police number 172 born 1851 at West Cholderton entered the force in 1874 and served to 1902." In the censuses he was at Ludgershall 1881, Tinhead 1891, and Edington 1901. Coincidentally he shared the same police collar number as William Fred 'Farmer' Brown of the Metropolitan Police and Chitterne.

Church Organ
The Willis Organ in Chitterne Church
The Willis organ in Chitterne Church has recently been tuned, cleaned and updated by an organ-builder who was trained by the original designer of the instrument.
Our organ was built in 1968 for Laleham Abbey Convent, Middlesex. The secondhand organ was offered to Chitterne Church in 1993, installed, and dedicated on 26 February 1995 by the then Bishop of Ramsbury, the Rt Rev Peter Vaughan.
This Willis Junior Development Plan Organ was designed by Henry Willis 4, the fourth Henry of the Willis family of organ builders. I know very little about organs so here I will quote AC who carried out the recent work and let him explain what the name means:
" "Junior" because they (the organs) were designed by Henry Willis, 4, who was then Junior to his father who was running the firm up until 1968. "Development Plan" because they were a series of models which started as a one manual organ with two stops and no pedals, and could be developed in stages to a two manual organ, a little larger than the Chitterne instrument, as and when funds became available. The Willis nameplate on the console IV-LVII denotes Henry Willis, 4, then the Opus Number. Opus 57 started as a one manual and pedal instrument. It gained the Swell organ, which I worked on in the early 1980s. "
Members of the Willis family of organ builders
The Chitterne Willis organ has been updated with a computer that enables recordings to be made. The recordings can be used at future services when no organist is available. I have heard a recording of AC playing the instrument and it sounded beautiful.
War Memorial 100
Field Marshall Viscount Allenby
On Sunday 28th August 1920 Field Marshall Viscount Allenby unveiled the Chitterne War Memorial to the fallen, and servicemen who had served, in the First World War. Field Marshall Allenby, who had taken command of the British Forces in Palestine in the war, was seen as a great hero at the time.
Edmund Allenby's connection to Chitterne was through his sister Faith who lived at Chitterne House with her husband Vice-Admiral Charles Lionel Napier.

For workers who spend most of their time out in hazardous situations, Personal Protective Equipment (PPE) clothing is an absolute necessity to keep them safe on site.
When you first think of Personal Protective Equipment, your first thoughts might be safety goggles, protective boots, and construction hats. But before PPE clothing became a mandatory staple for tradesmen, its origins date further back than you might realise.
Scruffs, the UK's leading experts in innovative safety wear, has taken a look at the history behind some of the most common PPE equipment and its evolution over the years.
In the beginning…
Personal protective equipment has a long history.
The first well documented use of PPE equipment was in World War One, in the form of respirators. The use of these respirators allowed the troops to escape the effects of harmful toxins and gas.
Outside military settings, PPE clothing also dated back to the middle ages. Blacksmiths would wear protective aprons, and hand gear to prevent themselves from being burned or to stop equipment from falling on their heads.
The modern industry has drastically evolved since then, with greater focus on protective workwear for a range of trade industries. PPE now extends to clothing, footwear, goggles and other garments that are all designed to protect an individual from injury.
Headgear history
Hard hats and headgear can be traced back as far back as soldiers in ancient times, who wore protective headgear when heading off to battle. The ironclad material was definitely heavyso heavy in fact often times when a soldier would fall off their horse, they would need help from others to get up again!
Nonetheless, the humble helmet played an integral role in the face of defeat.
Headgear in the form of hard hats also helped to protect construction workers and miners from potential injury. Today, the hard hat is a compulsory requirement for worksites.
They are now generally made of harder plastic materials and composites, including:
 - Fiberglass
 - Vulcanised rubber
 - Aluminium
 - Polyurethane
Some of these materials have the added benefit of being flame and heat resistant.
Seeing clearly and safely
The real breakthrough in eye protection safety came from Powell Johnson, an AfricanAmerican inventor who patented "eye protectors" in 1880. Welders, construction workers, and others in hazardous professions can thank safety goggles for helping to protect their eyesight. The 20th Century saw a real demand for increased high-quality protection, leading to more innovative and refined designs compared to the basic designs seen previously. Fashionable safety eyewear is now available, that workers can enjoy wearing, whilst still being highly functional. You can now even buy prescription goggles and glasses, which are in compliance with safety standards.
Image removed.Glove development
The origins of protective gloves date back to eighth century BC, where ancient poet Homer's Odyssey gives a description of Laertes using gloves to protect his hands from thorns while working in the garden.
Throughout the centuries, gloves have further expanded to a fashion statement, but are still being used as protective everyday protective wear.
There are now many types of gloves that are used on various jobsites. Though the overall design hasn't evolved much, you can now get gloves with flexi-options, fleece (for insulation) and waterresistant materials for improved function in wet environments.
Best foot forward
Footwear PPE didn't exist in industry until the late 1800s, when protective boots were introduced, reinforced with steel and made from stiff leather.
Modern safety boots are now designed to better protect the individual wearer, wiImage removed.th features including:
 - Water resistant and waterproof materials, such as Gore-Tex, to protect the wearer from penetrating liquids.
 - Puncture resistant soles and steel toe caps to prevent potential injury.
 - Weatherproof designs to protect the wearer from extreme heat or cold, by using varying levels of insulation.
The vast development of PPE equipment across the ages has greatly benefitted the modern trade industry. Its continuous innovation will ensure even safer measures for tradesmen while tackling dayto day tasks onsite.

AbstractStochastic linear programming problems are linear programming problems for which one or more data elements are described by random variables. Two-stage stochastic linear programming problems are problems in which a first stage decision is made before the random variables are observed. A second stage, or recourse decision, which varies with these observations compensates for any deficiencies which result from the earlier decision. Many applications areas including water resources, industrial management, economics and finance lead to two-stage stochastic linear programs with recourse. In this dissertation, two algorithms for solving stochastic linear programming problems with recourse are developed and tested. The first is referred to as Quadratic Stochastic Decomposition (QSD). This algorithm is an enhanced version of the Stochastic Decomposition (SD) algorithm of Higle and Sen (1988). The enhancements were designed to increase the computational efficiency of the SD algorithm by introducing a quadratic proximal term in the master program objective function and altering the manner in which the recourse function approximations are updated. We show that every accumulation point of an easily identifiable subsequence of points generated by the algorithm are optimal solutions to the stochastic program with probability 1. The various combinations of the enhancements are empirically investigated in a computational experiment using operations research problems from the literature. The second algorithm is an SD based algorithm for solving a stochastic linear program in which the recourse problem appears in the constraint set. This algorithm involves the use of an exact penalty function in the master program. We find that under certain conditions every accumulation point of a sequence of points generated by the algorithm is an optimal solution to the recourse constrained stochastic program, with probability 1. This algorithm is tested on several operations research problems.

Decision makers do not make choices in a vacuum. They make them in an environment where many features, noticed and unnoticed, can influence their decisions. The person who creates that environment is, in our terminology, a choice architect. In this paper we analyze some of the tools that are available to choice architects. Our goal is to show how choice architecture can be used to help nudge people to make better choices (as judged by themselves) without forcing certain outcomes upon anyone, a philosophy we call libertarian paternalism. The tools we highlight are: defaults, expecting error, understanding mappings, giving feedback, structuring complex choices, and creating incentives.

I've discussed the need to be a learner and lead learner in this era of education which includes maker education. What I find absolutely exciting about being a maker educator is that they need to be learners; dedicated and invested in attitudes and behaviors related to being lifelong learners as the maker movement is ever evolving with seemingly daily advances. I believe that being a lead learner involves documenting and reflecting on the iteration process that is common for maker education. I provided an example of this in my post, Educator as Lead Learner: Learning littleBits.
As a learner and maker educator who wants to keep developing my making skills, I decided to hack out an ugly Christmas vest. What follows is what I did and my reflections about the process of creating this vest:
Reflection on This Hack:
- None of the original hacks worked correctly the first time. It was very frustrating but I had a need to make it work. Failure was not an option even if it meant my hacks weren't as clean as I desired.
- Even though they weren't as clean as I originally pictured, there was joy in getting my hacks to work. It was rewarding and fun to see the finished vest.
- The most joy I felt was when I wore the hacked out ugly Christmas vest to my health club. It was fun to watch others reactions – their smiles, laughs, and comments were priceless when they realized all that was going on in my vest.
I have been offered an opportunity to teach maker education again at a local summer enrichment program during summer, 2016. Last summer was my first time around so I experimented with lots of different maker education activities to see what worked and didn't work with the 5 to 10 year old kids. I now have this foundation and can build upon this foundation. I love creating new learning activities and will be thinking of new ways to use the materials so my returning students will have new activities. I plan to blog about those activities as I formulate them so (1) I don't forget about them, (2) others will have access to them, and (3) folks will realize that maker education can be implemented with accessible, fairly cheap materials; that a makerspace is not required to do maker education.

- Each learner is given the task to make 4-6 LED throwies (with the intent that they aren't going to be thrown.
- Directions from Make Magazine:
- Pinch the LED's leads to the sides of the battery, with the longer lead (the anode) touching the battery's positive (+) terminal, and the shorter lead (cathods) touching negative (–). It should light up.
- Cut a 7″ length of strapping tape or electrical tape, and wrap the leads tightly to the battery so the LED does not flicker. Wrap once around both sides of the battery.
- The battery's positive contact surface extends around the edges of the battery, so don't let the short lead (cathode) touch it or you'll short the circuit.
- More about LED throwies can be found at _URL_
- Each learner is then given a magnetic dry erase board and the task to create a design using both their LED throwies and dry erase makers (like the opening photograph).
- Since it is a dry erase board, learners can be encouraged to create multiple iterations of their LED-based art pieces. Photos can be taken so the learners feel comfortable with erasing and creating new art works.
- Learners can work with partners and switch around their LED throwies creating new and unique designs.

- Small groups form a design on a larger classroom whiteboard. They all put their LED throwies on the larger magnetic, dry erase board. They all then use the dry erase markers to create a group mural.
This is a whole group example prior to me realizing they could have decorated their LED group creation with the dry erase makers.

In the midst of the implementation of common core state standards and no relief in sight from all the standardized testing, there's been a breadth of fresh air in the form of maker education entering into many classrooms. The Maker Movement is not easily defined nor placed neatly into a nice little box. It can be high tech or low tech; hacking what is or creating from scratch; it can be creating from building and arts materials or creating on the computer. We have entered into a convergence of several factors that are igniting the maker education movement.
The rise of maker culture has been slowly bubbling out of sheds, science labs, tech workshops, in schools and learning spaces. But, suddenly it is very present. The Imagination Foundation that has emerged out of energy and excitement of Caine's Arcade is raising funds and investing in projects that support maker activities in education. The New Maker Education Initiative, backed by a range of organizations including Intel and Pixar, has just launched its first project called Maker Corps. There are initiatives like the Make2Learn which aims to "leverage DIY culture, digital practices, and educational research to advocate for placing making, creating, and designing at the core of educational practice". Makers and Teachers Unite!
Some maker-related educational movements that gained traction in 2013 and will most likely gain more momentum in 2014 include:
- A focus on STEM (science, technology, education, and mathematics) and STEAM (science technology, engineering, arts, mathematics):
At a time when many people are asking how we can get more students interested in STEM fields, we are hearing from teachers who have found making to be a great way to get students excited and engaged in their classrooms. We are seeing making occurring in subject classes such as math or science — in classes specifically listed as maker classes — and in a variety of less formal settings such as clubs and study halls. Many of these projects incorporate a variety of STEM topics. (Engaging Students in the STEM Classroom Through "Making")
- Economical, open source, and accessible robotics and electronics tools like Arduino, Rasberry Pi, Makey-Makey, Little Bits:
New open-source microcontrollers, sensors, and interfaces connect the physical and digital worlds in ways never before possible. Plug-and-play devices that connect small microprocessors to the Internet, to each other, or to any number of sensors mean that low-cost, easy-to-make computational devices can test, monitor, and control your world. They offer much more than just "hands-on" crafting—these tools bring electronics, programming, and computational mathematics together in meaningful, powerful ways. We must reimagine school science and math not as a way to prepare students for the next academic challenge, or a future career, but as a place where students are inventors, scientists, and mathematicians today. (How the Maker Movement is Transforming Education)
Think of the Maker Movement as DIY for technology. It's not just a passing fad – web tools like KidsRuby, Gamemaker, Scratch, Storify and Mozilla Webmaker make it possible for people of all ages to learn to code, build games, and re-mix media. For libraries and schools, the Maker Movement means new opportunities for promoting digital, media, visual, and critical literacies (21st century literacies). (Inanimate Alice and the Maker Movement)
- An interest in and focus on design thinking both in educational and corporate sectors:
Making is a way of bringing creativity, authentic design thinking, and engineering to learners. Tinkering is the process of design, the way real scientists and engineers invent new things. Such concrete experiences provide a meaningful context for understanding abstract science and math concepts while often incorporating esthetic components. Creating opportunities for students to solve real problems, combined with imaginative new materials and technology, makes learning come alive and cements understandings that are difficult when only studied in the abstract. (Why we're excited about the Maker Movement, maybe you should be too!)
3D Printing is one of the most disruptive technologies around. These printers are affordable, personal fabrication tools, compact enough to sit on any desktop, and allow anyone at any skill level to become producers, inventors and artists. Students participate in project-based learning that is experiential in nature and has real-world applications. 3D printing projects engage students in the world around them, kindles a curiosity about how machines work, how objects fit together, and how the designers, architects, and inventors who build the products, spaces and technology in their lives have found solutions to a variety of design problems. (Makerbot Curriculum)
- Global making initiatives like the Cardboard Challenge:
The goals of Imagination Foundation, who sponsors, the Cardboard Challenge is in line with many Maker Education Initiatives:
1. Instill Creative Thinking as a Core Skill and Social Value
Give kids the tools to develop as creative thinkers who can take on the jobs of the future, seek innovative and resourceful solutions, tackle social issues and find happiness.
2. Give Kids Opportunities to Create and Learn Based on their Passions
Help children find and develop their passions through play

APPLICATIONS OF TECHNOLOGY:
- In-the-field cryogenic microscopy sample preparation
- Microbial ecology
- Cryo-TEM laboratories
- Extremophile sampling
- Works in remote locations and extreme environments
- Simple operation
- Affordable alternative for labs lacking cryo-plunging equipment
A Berkeley Lab team led by Luis R. Comolli has developed the Portable Cryo-Plunger, a lightweight, portable flash-freezing apparatus that can safely preserve biological samples in the field for subsequent analysis using cryogenic transmission electron microscopy (cryo-TEM), an approach to study near-intact bacteria, viruses, and protein structures if they are flash frozen in vitreous (non-crystalline) ice. The Portable Cryo-Plunger has successfully prepared cryo-TEM samples in real time, enabling the study of microbial communities that have never been cultured in a laboratory setting.
As demonstrated in one configuration of the device, weighing 4 kg and standing 71-cm tall, the Portable Cryo-Plunger can be transported on foot to a sampling site (see image below). Mounted on a tripod, it can be set up in difficult terrain, such as the interior of a mine or the shores of a salt lake. The Portable Cryo-Plunger is designed to fit in its base, a medium density foam cylinder Dewar containing a liquid nitrogen bath, surrounding a liquid ethane or propane cup where the flash freezing (~-188 °C) takes place. A droplet of sample is applied to a standard cryo-TEM grid, and the grid is placed at the plunger tip. At the top of the plunger is a spring-loaded handle that is used to drive the sample tip quickly into the flash-freezing cup.
The use of Cryo-TEM has been limited because most specimens must be flash frozen in a lab, and by the time they reach the lab from remote field locations, they can be seriously degraded. Freezing eliminates damage caused by traditional fixation and dehydration of specimens, affording more realistic and detailed views of bacteria, including images of delicate extracellular structures whose surfaces are exposed to the environment.
Since the Cryo-Plunger costs less than a tenth of the price of commercially available cryo-TEM flash freezing devices, it can be used in laboratories that do not have the resources to acquire automated equipment. The device also can foster collaborations between cryo-TEM labs and field researchers who previously lacked access to cryo-TEM microscopy.
The Cryo-Plunger is designed for ease of operation in the field. This version, set up on a tripod, weighs only 4 kg.
DEVELOPMENT STATUS: Fully functional field-tested prototype.
STATUS: Patent pending. Available for licensing or collaborative research.

What is the Keep?
The Keep, the site of Bermuda Maritime Museum, was the citadel or
great fortress of the Dockyard defences. It is a six-acre fort,
with seven irregular bastions, named 'A' to 'G',
designed to protect the Dockyard from enemy attack. The lower grounds
of the Keep contain large Sea Service stores, which in 1857 comprised
two bombproof magazines for 6,540 barrels of powder, a shell store,
a filling room and a shifting house. Lighters, or small boats, were
dispatched from the Keep Pond to serve the fleet at anchor in Grassy
Bay. Lighters would provide ships with munitions from the Keep stores,
or safely remove munitions from ships under repair in the Dockyard.
How is the Museum funded?
The Museum is a non-governmental, not-for-profit charity (Bermuda Charity No. 136), meaning
the institution depends on private and corporate donations, membership
dues, admissions, and events rentals.
How many visitors does the Museum receive?
There are approximately 50,000 visitors to the Museum annually,
making it Bermuda's most visited Museum attraction.
How many objects are in the Museum's collections?
There are more than 30,000 objects in the Museum's diverse
collections, including photographs, documents, plans, books, oral
testimonies, archaeological specimens, boats, ship models, and a
wide range of maritime artifacts.
Where do the Museum's collections come from?
The Museum's impressive collections are mainly donations from
the public and institutions, while some come from archaeological
How long have the dolphins been at the Museum?
Dolphin Quest has operated out of the Keep with its dolphins resident
in the protected waters of the Keep Pond since September 1999, when
Hurricane Gert destroyed the Dolphin Quest habitat at the Fairmont
Southampton Princess Hotel.
Why are there sheep on the upper grounds of the Museum?
The sheep you'll encounter are our trusty lawnmowers. They
trim all the grass and vegetation on the Upper Grounds year-round.
The flock is Katahdin sheep, a special breed that requires no shearing.
Local farmer Bascome of Westover Farm in Somerset manages the flock.
Please do not try to follow, touch, or feed the sheep as they are
extremely timid creatures and scare very easily!
Does the Museum manage the entire historic Royal Naval Dockyard site?
The Museum manages the Keep, while the West End Development Corporation manages the majority of the remainder of the Dockyard site.

Predicting protein structures and simulating protein folding are two of the most important problems in computational biology today. Simulation methods rely on a scoring function to distinguish the native structure (the most energetically stable) from non-native structures. Decoy databases are collections of non-native structures used to test and verify these functions.
We present a method to evaluate and improve the quality of decoy databases by adding novel structures and removing redundant structures. We test our approach on 20 different decoy databases of varying size and type and show significant improvement across a variety of metrics. We also test our improved databases on two popular modern scoring functions and show that for most cases they contain a greater or equal number of native-like structures than the original databases, thereby producing a more rigorous database for testing scoring functions.

In her dramatic monologue 'The Dolphins", Carol Ann Duffy has presented herself as an animal-lover and protested against the exploits of animals and other natural elements by man. Though the poem only speaks of the deplorable condition of the dolphins who are forced to live in a pool to perform tricks in circus, the theme actually goes beyond this. In a broader view, the dolphins are mere representatives of all such creatures receiving ill-treatments in the hands of man.
The poet here expresses the sadness in the dolphins' mind through their own voice using the technique of dramatic monologue. The dolphin says that they are in their 'element' to mean they are still living in water, but they are kept away from their natural habitat, i.e., the ocean. They are not free. Freedom is what the dolphin finds most important to be happy. They are not 'blessed' anymore as their movements are restricted in a pool and are guided by a man. They cannot even move according to their will; they have to perform tricks as the man wishes in order to entertain people. So, the dolphins are now used for the monetary purpose of humans. They have to balance themselves on a coloured ball. The dolphin regrets repeatedly:
We were blessed and now we are not blessed.
The dolphin is sad as it is living a monotonous life in the same space. It is in sharp contrast to what the life was like when they were in the sea. The space is limited. A man is there constantly above them guiding their movements and making them feel guilty. The moon has disappeared for them, not only literally but also metaphorically. They can no longer see the moon as they are not in the open sea, and the cheerfulness of their free life has now turned gloomy.
The dolphin remembers its happy days of the past. It finds its own reflection in the other dolphin's actions. Its heart turns to stone when it hears the "music of loss" from the other dolphin.
… Music of loss forever
from the other's heart which turns my own to stone.
So, there is a sense of loss and there is hopelessness. The only thing they have got to entertain themselves is a plastic toy. That is not the ideal thing they used to use living in the open ocean. The man's whistle makes them sink to the limit of the pool. There is a tone of suppression. Humans are toying with the innocent animals' lives. The very last line has a sarcastic tone:
There is a man and our mind knows we will die here.
It is as if where there is a man, there is impurity, there is distortion, artificiality and destruction of everything natural. In fact, the existence of a man above them has been repeated in every stanza of the poem to highlight the authority of man not only over the dolphins but also over nature and most other natural creatures. The way man is expanding their reach in this universe and trying to use natural elements in their way, they may eventually end up making a mess with the balance of this universe and its natural aspects. We are slowly but surely destructing nature and its purity.
The poet here raises her voice against this destruction through human cruelty towards animals. The dolphin acts as the poet's voice to convey her message towards the readers that we should respect the rights of animals to live in their natural habitat and should not inflict our cruelty on them.

People often fail to understand that the relative brain of a dolphin is only second to that of a modern human being. They live in large complex social groups and swim vast distances in open ocean. But while in captivity they can only swim in circles in tanks and are denied to stay in natural habitat and are forced to perform meaningless tricks and are often taken away from their family.
It is just like a man in a prison blindfolded, the dolphins feel the same way. Accounting to all the years many of the dolphins died while in captivity in touch tanks. By this poem the poetess wants to show us the torture the animals receive in the hands of the people. The poetess expects us to see the world from their perspective too and to protect the life of the innocent animals and demands to stop the exploitation of wildlife in the name of self-entertainment. Most of the countries have already banned the dolphin captivity.

Coming soon: The Largest Flare System in Asia
 This technology is coming soon to the largest flare system in Asia
 Giant flames -- as part of flare systems -- are key to keeping refineries running around the world.
 Flare technology helps refineries safely dispose of toxic or flammable gases, while its burners reduce and better control emissions, and more efficiently generate heat.
 At Hengli Petrochemical in China, Honeywell's Callidus flares will be used in a new, 5,000-ton-per-hour flare system that will be the largest of its kind in Asia when it is completed construction in 2018.
 Here's how the system works:
 Burners provide the heat
 Here is a bottom's up view of a refinery burner. Burners generate heat for refinery processes and typically are fueled by gas. Hengli will use 400 Callidus low-nitrogen oxides (NOx) burners, covering the entire complex.
 Cooler temperatures
 The reason the flames are blue is because they burn cooler, which is a sign of low-NOx combustion.
 Gas in, vapor out
 Modern flare systems compress waste gases with steam or air inside the flare system, then burn the mixture to produce a low-particulate product with water vapor and carbon dioxide.
 Watch for flares
 Flare systems are ready 24/7, which is why flames can occasionally be seen coming out of pipe stacks. Pollutants such as smoke and flare particulates cause air pollution and other environmental consequences that have a serious impact on public health. However, flare systems such as Hengli work to minimize the release of such pollutants.
 Reduce emissions
 A pipe stack like this will be erected at the Hengli refinery by the end of 2018. A customized design can help reduce emissions. For Hengli, the technologies will reduce emissions to half of the regulatory limit in China.

Wandle Valley Living Landscape - London Wildlife Trust
The River Wandle is a unique south London chalk stream.
The Wandle has been identified as one of London's five flagship rivers by the Environment Agency.
Once, this river teemed with wildlife including trout and otter, but by 1960 it was officially declared a sewer. Subsequently much-improved through active conservation effort, the Wandle now supports fish and other wildlife, but still flows through significant stretches of industry, residential areas and commercial centres.
This scheme aims to restore six kilometres of urban river habitat in the River Wandle catchment to create a thriving landscape that supports a rich variety of species and habitats, provides connectivity for people and wildlife, is adaptable to climate change and encourages access and enjoyment by people.
The Wandle Valley is a flagship urban river restoration project, demonstrating how partners can work together to restore a functional river corridor for people and wildlife.
Its value as a regional priority has been recognised by Natural England and the area has been proposed as a new regional park.
We have focused our recent efforts on habitat restoration in-stream and on our Wilderness Island nature reserve.
We are also developing a strategy for the future reintroduction of water vole.
Start date: 2008
Scheme area: 500 hectares
Trust reserves within the scheme
This scheme is helping species including...
Current threats to the landscape:
Habitat loss and fragmentation, pollution, climate change, inappropriate development, non-native species (e.g. mink, Chinese mitten crab).

EMANCIPATION OF PERILOUS LEACHATE'S FORAY IN A CITY ENVIRONMENT: EXAMPLE FROM ILLEGAL WASTE DUMP SITES IN KUBWA-ABUJA, NIGERIA.
Abstract:Cities in Nigeria face with problems of solid waste on illegal dump-site that could encourage poor sanitary conditions and unhygienic standard. This study examines the perilous impact of leachate's foray in Kubwa-Abuja, with the purpose to enlightening city inhabitants from dumping refuse indiscriminately on unauthorized sites which may proactively have composite consequences around dump-sites. Kubwa-Abuja has three prominent illegal dumpsites which were designated into zones. the three zones are within residential houses of; 100-300 meters radials from the dumpsites. Data for the study were obtained from primary and secondary sources. The primary source employed the administration of 200 questionnaires each to selected household members in the three designated zones and oral interview were conducted to random selected public members and the refuse control agencies in as to obtain information about impacts incursion of the unauthorized dumpsites in the area. Other source reveals the related literature on the work. Correlation was used to analysis the hypotheses set. Results show significant differences as residents' susceptibility to health related diseases and effect of leachate from dumpsites to the nearby water. Policy measures are suggested on how best to curtail the impact of illegal dumpsites on the city environment.


Robot Scouts May Assist Humans in the Exploration of the Moon
Robots have been the trailblazers in space exploration. In particular, Ranger, Surveyor, and the Lunar Orbiters paved the way to the lunar landings in the Apollo Program. Now, tests are planned to see if robot scouts can aid human explorers on future missions to the Moon. What these current and future robots will do that sets them apart from the earlier machines is that they will work closely with the humans on the moon's surface.
During Apollo surface operations, the astronauts did recon and geological exploration at the same time. In the return to the Moon around 2020, robots will be tasked to reconnaissance. This should make the astronauts work more productive. During the upcoming testing of the K10, researchers hope to show that robots can increase the science return of the human missions. Check out the article at the link below for more information.

Colour-Based Binary Discrimination of Scarified Quercus robur Acorns under Varying Illumination
AbstractEfforts to predict the germination ability of acorns using their shape, length, diameter and density are reported in the literature. These methods, however, are not efficient enough. As such, a visual assessment of the viability of seeds based on the appearance of cross-sections of seeds following their scarification is used. This procedure is more robust but demands significant effort from experienced employees over a short period of time. In this article an automated method of acorn scarification and assessment has been announced. This type of automation requires the specific setup of a machine vision system and application of image processing algorithms for evaluation of sections of seeds in order to predict their viability. In the stage of the analysis of pathological changes, it is important to point out image features that enable efficient classification of seeds in respect of viability. The article shows the results of the binary separation of seeds into two fractions (healthy or spoiled) using average components of regular red-green-blue and perception-based hue-saturation-value colour space. Analysis of accuracy of discrimination was performed on sections of 400 scarified acorns acquired using two various setups: machine vision camera under uncontrolled varying illumination and commodity high-resolution camera under controlled illumination. The accuracy of automatic classification has been compared with predictions completed by experienced professionals. It has been shown that both automatic and manual methods reach an accuracy level of 84%, assuming that the images of the sections are properly normalised. The achieved recognition ratio was higher when referenced to predictions provided by professionals. Results of discrimination by means of Bayes classifier have been also presented as a reference.

School district aims at boosting skills
Two out of every three Langley Grade 9 students can't solve math problems by themselves, according to a just-released report prepared by Langley school district superintendent Cheryle Beaumont.
The numbers cited in the annual "Superintendent's Report on Achievement" show just 31 per cent of Grade 9 students in the 2009-2010 school year met "numeracy" skills, which are defined by the provincial ministry of education as the ability to appropriately apply mathematical concepts and procedures without a teacher at their side.
That left 69 per cent who required some help or "close, ongoing assistance" by an instructor.
Beaumont, in her report, notes the district is trying to determine the impact poor Grade 9 math skills may be having on graduation rates, since students who have trouble with the more advanced math of secondary school may be less likely to finish Grade 12.
The report flags a number of other areas of concern.
It shows that roughly one out of every five Grade 1 Langley students finished the 2010 school year unable to read short, simple illustrated selections on their own.
That is based on numbers released by the school district and the provincial education ministry that show 246 of 1359 or 18 per cent of pupils "left Grade 1 still not reading at grade level."
Provincial standards state a Grade 1 student will "fully meet expectations" for literacy when they can read short age-appropriate passages independently."
The Grade 1 stats still represent an improvement from the previous school year when 364 of 1296 or 35 per cent of Grade 1 students failed to meet expectations.
"The district is committed to having all students reading at grade level by the end of Grade 3," the Beaumont report states.
Langley Grade 10 students showed a drop in reading skills, with the percentage of students meeting or exceeding expectations falling from 93 per cent in the 2008-2009 school year to 85 per cent in 2009-2010.
The news is not all bad. In most categories, student performance is improving.
Overall, the number of students who graduate Grade 12 has increased from 78 per cent in 2008 to 83 per cent in 2010, the report states, better than the provincial average.
However, boys are lagging behind girls, with 78 per cent of male students gradating Grade 12 compared to 87 per cent of female students.
Langley First Nations students still have a relatively high drop-out rate, with four out of 10 failing to graduate Grade 12. That's still better than the provincial average for aboriginal students.
Only one in two Langley graduates goes on to university or college-level studies.
"While 2009-2010 was undoubtedly a very challenging year, we have made remarkable progress," Beaumont said in a written memo to district trustees.
"Much work remains to be done. However, the initial areas of the district that needed to be stabilized are being addressed and the work is underway."

A number of our labs are workbook-style labs, where instructions and questions are contained in a PDF workbook. If you would like to fill out the workbook on your computer instead of on paper, Adobe (the creator of the PDF format) has a free software solution called Adobe Acrobat Reader which makes this easy.
To use this feature, follow these instructions:
- Install the latest version of Adobe Acrobat Reader. You will need a recent version, as older versions do not include the capability to edit PDFs. You can download the free "Reader" software from Adobe's website. (NOTE: There is a professional version of Adobe Acrobat which costs money, but that version is not needed in order to fill out SimBio workbooks.)
- Launch the Adobe Acrobat Reader application, and open the SimBio Virtual Labs workbook.
- Under the Tools menu, select Comment. A commenting toolbar will appear.
- In the Comment toolbar, find the Add Text Box tool —. You can hover over the different tools with your mouse until you see the Add Text Box tooltip appear.
- In the area where you want to type an answer to a question, drag out a box with the mouse and start typing.
- If the question asks you to make a drawing, you can use the Draw free form tool — — and the Drawing Tools —
- When you are done filling out the workbook (and periodically as you are working through it, just to be safe), save it using the Save or Save As commands in the File menu.
- You can then email that file to your professor to turn in your completed workbook.

As statistics point to a rise in avoidable deaths among high school athletes, because of heat exhaustion, concussion, even cardiac arrest, more schools are looking at adding athletic trainers to their rosters. The trainers are taught to look for possible problems in young players before the serious symptoms show up. And schools like Fairfax provide special training for their athletic trainers and coaches, so they are ready for anything.
So there's an emergency action plan that coaches have for every facility that they're at, where they practice and as well as where they compete.
Athletic trainers are also the medical experts away from home.
The Fairfax county model costs several million dollars a year - but many school districts across the country are looking at it as a way to protect their young athletes.


How to find out that "/nvdli-nano" is the name of the directory in the docker container?
Hi guys, I am currently going through the DLI Course and when mounting a directory to the docker container using volume command we set the path of the container as "/nvdli-nano". My question is how do we find this out?
I'm sorry if the question may seem a little noobish, I'm quite new to docker.
--volume ~/nvdli-data:/nvdli-nano/data
Hi, this argument to docker run means that your user's ~/nvdli-data folder on your device (outside of container) will be mounted into the container and appear at /nvdli-nano/data (inside the container)
The /nvdli-nano path inside the container is where the notebooks reside and was how the container was setup. So knowing that path requires knowledge of how the container was built. Or you can typically launch a container and just look around for the different folders.

Can you choose to other activities such as the size and shape of the mattress, it's also advisable to pay attention in addition to shade variety. Choosing a mattress of white on white room would need to be adjusted to the size of the space. Variety of these beds so your room white does not appear cramped or whole since one to be truly accurate can select the mattress.
In case you are looking for your companion of course and a bed for you personally select the mattress measurement is sufficient for 2 folks. But do not be too large in addition to area can be taken up by it. For you personally along with your partner you select enough calculate the only real mattress.
Actually the latest types of mattress today many are good-and can be utilized for anything else. Beneath the sleep where the portion will soon be employed like a clothes wardrobe or storage space. The mattresses have contemporary white color was selected as it is good-and relative to the idea of white shade.
But when you are buying Pedestal Fans; Ceiling Fan. (exceptional Ceiling Fans Manufacturers #8) to your kid or for your own (with no associate) it's greater should you choose a mini bed (simple poor). By doing so, the space place won't feel crowded. This bed that was mini is correctly useful for teenagers or kids.


Dynamic Range (contd.)
RAW headroom
The second part of the dynamic range story is of course the additional headroom available in RAW files. Experience has told us that there is typically around 1 EV (one stop) of extra information available at the highlight end in RAW files and that a negative digital exposure compensation when converting such files can recover detail lost to over-exposure. Much experimentation lead us to eventually use Adobe Camera RAW for conversion with the settings show below to retrieve the maximum dynamic range from our test shots.
It would appear that the EOS 5D's RAW files contain just over one stop of extra highlight detail, although interestingly this was pretty much unavailable in any Canon RAW converter because of their conservative approach to potentially incorrect data. At the shadow end it is possible to lift shadow detail however this also increases the visibility of noise. Another interesting artifact here was that using the default ACR conversion we lost a tiny bit of highlight range and about a stop of shadow range, it appears that ACR's default 'Medium' tone curve is a little more contrasty than the camera curve and also that ACR is doing less noise supression in shadows (hence it hit our lowest acceptable SNR earlier than in-camera JPEG).
 - ACR Best: Exp. -1.25 EV, Shadows 0, Bright. 50, Contrast 0, Curve Linear
The issue with highlight data above the normal 'clip' point is that the RAW converter can not be sure that it is 100% color correct, it appears as though rather than risk false color the Canon converters simply discard it. Adobe Camera RAW (and some other third party RAW converters) however do attempt to reproduce as much extra detail as possible and where a single channel is completely clipped they instead produce a gray of the correct luminance (seen below).
Real life example
Step wedge shots are great for analyzing the optimum response from a camera but nothing beats a real life example to get some idea what all this means. Below left you can see an example of an EOS 5D image with a large area of over-exposure. Using Adobe Camera RAW we produced two additional versions of this shot, the first with the 'optimum' -1.25 EV compensation and the second with a -2.00 EV compensation. While initially the -2.00 EV shot looks better a closer look shows that where ACR could not correctly calculate the color of a pixel it instead turns it gray (with the correct luminance), some of the brickwork has its correct color, other bricks are gray. The -1.25 EV shot shows no less detail it's just about optimum for the amount of additional information available in this RAW shot.
Default conversion (original) -1.25 EV, lower contrast -2.00 EV, lower contrast
Different RAW converters
Lastly it's worth comparing a couple of other RAW converters. In these cases we used -2.00 EV, despite the fact that it's more than the available headroom to explore how each converter deals with the lack of complete (accurate) data for some pixels. As you can see Adobe Camera RAW produces the most natural looking image with the best 'guess' for the value of pixels with inaccurate color data, RawShooter comes in second and Canons DPP takes the conservative approach, if it can't be sure of the pixel color then it just leaves it white / gray.

Single-Acting Hydraulic Cylinder (Simple)
Basic functionality of single-acting hydraulic cylinder
The Single-Acting Hydraulic Cylinder (Simple) block represents a simplified version of a hydraulic cylinder, developed for applications where only the basic cylinder functionality must be reproduced, in exchange for better numerical efficiency. For these reasons, such factors as fluid compressibility, friction, and leakages are assumed to be negligible. The hard stops are assumed to be fully inelastic, to eliminate any possible oscillations at the end of the stroke. The model is especially suitable for real-time and HIL (hardware-in-the-loop) simulation, if such simplifications are acceptable.
The model is described with the following equations:
|F||Force developed by the cylinder|
|v||Cylinder rod velocity|
|vR,vC||Absolute velocities of cylinder rod and cylinder case, respectively|
|p||Pressure at the cylinder inlet|
|q||Flow rate at the cylinder inlet|
|x0||Initial distance between piston and the cap|
|Fc||Hard stop force|
|xE||Distance the piston can travel to fully extend from initial position|
|xR||Distance the piston can travel to fully retract from initial position|
The main difference between this block and the Single-Acting Hydraulic Cylinder block is the representation of the hard stop:
The Single-Acting Hydraulic Cylinder block utilizes the elastic model of the stop, which is essentially a combination of a spring and a damper, connected in parallel. The stiffness of the spring, which represents contact stiffness of colliding bodies, is very high, resulting in high-frequency, low-magnitude oscillations at the moment the bodies collide. These oscillations can hardly be noticed experimentally, but they are difficult to process by a numerical simulation and generally decrease numerical efficiency.
The hard stop in the Single-Acting Hydraulic Cylinder (Simple) block is represented with the inelastic model, which is essentially a viscous damper with the penetration-dependent damping coefficient. This coefficient is referred to as the penetration coefficient. With inelastic model, no oscillation is generated during an impact, resulting in improved numerical robustness and efficiency. But inelastic stop model has a feature that you must consider while selecting the model: colliding bodies continue slowly moving into each other as long as the contact is loaded with the compressing force. In real life, this phenomenon is similar to collision of two bodies separated by a sizable layer of viscous liquid. It takes some time to squeeze the liquid before bodies themselves come into contact.
Connections R and C are mechanical translational conserving ports corresponding to the cylinder rod and cylinder clamping structure, respectively. Connection A is a hydraulic conserving port associated with the cylinder inlet. The physical signal output port P shows current rod extension.
Pressure at port A generates force in the direction specified by the Cylinder orientation parameter.
Basic Assumptions and Limitations
Friction between moving parts is not taken into account.
Inertia effects are not taken into account.
Fluid compressibility is not taken into account.
Leakage flows are assumed to be negligible.
The hard stops are assumed to be fully inelastic, as explained above.
- Piston area
Effective piston area. The default value is
- Piston stroke
Piston maximum travel between caps. The default value is
- Initial distance between piston and cap
The distance between the piston and cap at the beginning of simulation. This value cannot exceed the piston stroke. The default value is
0, which corresponds to the fully retracted position.
- Penetration coefficient
Specifies the penetration property of colliding bodies. The higher the value of the coefficient, the less the bodies penetrate into each other, but the sharper the increase of the impact force. To find out the value of the coefficient for a particular application, it is recommended to run the same model with different hard stop models (or with different cylinder models) until they show close results. The default value of the coefficient is
- Cylinder orientation
Specifies cylinder orientation with respect to the globally assigned positive direction. The cylinder can be installed in two different ways, depending upon whether it exerts force in the positive or in the negative direction when pressure is applied at its inlet. If pressure applied at port A exerts force in negative direction, set the parameter to
Acts in negative direction. The default value is
Acts in positive direction.
The block has the following ports:
Hydraulic conserving port associated with the cylinder inlet.
Mechanical translational conserving port associated with the cylinder rod.
Mechanical translational conserving port associated with the cylinder clamping structure.
Physical signal output port that outputs rod extension.
