Will the game be cancelled if it is raining?
For U10, U12, and U15, games will not be cancelled due to rain. The referees make the determination if the fields and conditions are unplayable, and that decision will not be made until the referees arrive at the fields and make the determination. Please come to the games prepared to play. For U6 and U8, the coaches together at the fields determine if the conditions are too bad to play.
What is the correct Age Division for my child?
Your child's division is determined by his/her age at the end of the calendar year. For example, if your child will be 9 years old (having a birthday in November) before the end of the current calendar year, your child will be playing in the U10 Division. If your child is not under 10 years old on December 31 of the calendar year, then your child does not play in the U10 division. He/she plays U12.

These services are aligned with National Cyber Security Centre (NCSC) component-driven risk assessment guidance and utilise cutting-edge defence algorithms improve the cyber resilience of your business. Click the logo below to find out more.
Expertise and innovation and in cyber defence, leveraging core capabilities in modelling, simulation, data analytics and visualisation
Recent years have witnessed a dramatic increase in the level of threat from cyber-attacks against government, enterprise and the domestic environments. The threat comes from a variety of sources, ranging from lone hackers through to the new wave of internet-aware terrorist organisations, sophisticated cyber criminals and nation state actors. The effects of these cyber-attacks can range from minor impact to major existential threat. This dramatic increase in the level of threat has led to an increasing focus on cyber security and the resilience of systems and organisations to cyber-attacks. Riskaware plays an active role in this area, developing both software tools and new techniques to improve cyber resilience.
Riskaware is developing systems which allow both analysts and leaders to understand how an organisation, process or mission is dependent on cyber infrastructure and how vulnerabilities there can result in critical risks. Our systems provide rapid update of the security status of an enterprise cyber infrastructure, along with assessments of the potential impact of cyber threats and how protective measures will help resolve the situation. Our approach is based on an automated capture of network architecture schematics and automated vulnerability mapping. Vulnerability analysis and visual analytics are used to allow the user to understand the "big picture" of the organisational or mission impact, to prioritise the key threats in terms of their potential impact and to find resolutions for key issues.
Another important aspect of cyber security is the inadvertent leakage of information. This can often be an indication that a cyber-attack has occurred, although it can also have an innocent explanation, such as enthusiasts or employees posting information online. Even so, this information can provide a potential cyber-attacker with information they can use to design a social-engineering or full cyber-attack on the organisation. Riskaware have successfully developed open-source intelligence tools to identify and analyse information leakage so that the likely source and the level of leakage can be understood and the potential impact quantified.

A Tar Pit to Dye In by Ed Werstein
A Tar Pit to Dye In by Ed Werstein. Kelsay Books, 2018.
Reviewed by Ashley Ehman
The saying goes, "There are two sides to every story." My immediate question: why are there only two sides to a story? Is there not more to be said? I believe that Ed Werstein and I would agree on such a fact. Throughout his chapbook A Tar Pit to Dye In, he is constantly wavering on a line between the two sides; the living and the lost, the good and the bad, science and imagination. His pages discuss the black and white aspects of the world as they are explored through a flurry of greys. And there we are, the people inhabiting this world, existing as a herd of monochromatic sheep.
Upon delving further into the book, this theme of parallelism exists within the structure of the poems as well. A majority of his pieces are written in free verse, which lack any sort of firm rules to guide its shape. Werstein uniquely uses this fluid form to solidify his thoughts on the page. In "The Best We Can Hope For," he again tackles the presence of duality in life, using happiness and sadness as his instruments. The poem explains:
An hourglass floating
on an undulating sea
tilting sometimes toward
sometimes away
is the best we can hope for.
This poem explores life as an hourglass, where instead of two options, happy or unhappy, there is a varying degree that can occur between these extremes. The world does not exist as one or the other. The symbolism of the hourglass can also be connected to the constant theme of mortality.
The idea that we only live one life is present in all three sections of the book. An intriguing example takes form in the poem "Another Useless Headline Poem," one of the few poems that has variety of repetitive shape. The poem begins:
I've been thinking about flesh
and blood
and guts
and bullets
and assaults
on our sanity.
This short phrasing continues into the next stanza. Initially, it would seem the author did this to enforce some sort of significance on his words, which is not entirely untrue. The context of the poem also plays into this. At the top of the page, there is an epigraph that reads "US Senate Response to Orlando: Nothing." The only insight to what this could be referencing is in the date listed below: June 21, 2016. This article was published nine days after a shooter opened fire in a gay dance club. The name of the club? Pulse. Intentional or not, the breaking of his stanzas into shortened phrases gives the poem a 'beating' sound, much like the pulse of a heartbeat. This artistic styling shows that Werstein goes beyond the words of the page by using other elements to give meaning to his work.
While I could go on about how the author captures sarcasm with seriousness, humor with humility, and politics with perspective, I digress. Werstein used a variety of techniques to explain the world in a way that is unseen to the common eye. He has much to say, and captures this in a concise and interesting fashion that goes beyond the words on the page. His poems showcase a writing ability only met by someone who loves their craft. Even in his closing, he leaves the reader with one last parallel, a single written word: "Speak!"

F for fat: obesity on report cards?
Illustration: Ron Tandberg.
A CHILD'S weight should be included in their school report as part of a radical plan to tackle the obesity crisis, according to the man who led Australia's successful response to the AIDS epidemic.
David Penington, who chaired the National AIDS Task Force from 1983 to 1987, also suggests the GST be raised and extended to a broader range of foods to encourage healthy eating.
Professor Penington, a former Melbourne University vice-chancellor and dean of medicine, told an obesity summit in Canberra this week that the inclusion of weight in primary school reports could spark discussion between teachers and parents about their children's diet and level of physical activity.
''Some obesity does start in early childhood just with very bad eating habits,'' Professor Penington said.
''It's not that I want the schools to be seen as the body responsible, but nonetheless use the school environment as a way to contribute to ensuring that the broader issues are there for discussion.''
Child and adolescent psychologist Michael Carr-Gregg said schools could play a role in preventing obesity but warned that placing a child's weight on their report card could trigger depression and anxiety and lead to bullying.
Christine Morgan, chief executive of the Butterfly Foundation, which works to prevent eating disorders, said weight was not the best measure of health, and reporting weight could undermine children's self-esteem.
''I would be very concerned that this would have some very detrimental impacts on a young person and would actually be very counterproductive,'' she said.
Australian Education Union federal president Angelo Gavrielatos said schools had a role to play in teaching children about healthy lifestyles, but more resources should be directed to supporting parents.
''We cannot continue to expect more and more from schools, which takes away from the core responsibility of teachers,'' he said.
A federal Health Department spokeswoman said placing children's weight on report cards would not be a federal responsibility, and the department's approach was to promote healthy eating and physical activity.
Coalition health spokesman Peter Dutton said: ''We support people having the information they need to make choices for themselves and their children. We do not support reporting on a child's weight on their report card.''
Obesity Australia chairman John Funder said the idea would need to be implemented sensitively, and suggested parents of overweight children be offered the chance to talk to their physical education teacher.
Professor Penington said the GST could be changed to encourage those in low socioeconomic groups - who suffer disproportionately from obesity - to eat more fresh fruit and vegetables and less processed food. Currently fresh food is GST free, but the tax applies to hot takeaway foods, ice-cream, biscuits, confectionary, soft drinks and some other prepared foods.
Professor Penington said fresh fruit and vegetables should remain GST free, and an expert group could decide which other foods remained free of GST based on their nutritional value. He suggested other foods be subject to the tax, which could be raised to provide extra revenue to cover rising healthcare costs.
''Telling people over television to eat better doesn't do very much,'' Professor Penington said. ''Price signals do influence behaviour.''
Since 1980, the proportion of Australians who are obese has almost tripled and now stands at 28 per cent. About one-quarter of Australian children are overweight or obese.

16 Ships Pollute More Than All Cars in the World
Just 16 of the worldâ€™s largest container ships can produce more pollution more than all the cars on the planet.
In an editorial report in Britain's Daily Mail, an award-winning science writer Fred Pearce, author of Confessions of an Eco Sinner, writes that the super-ships that keep the West in everything from Christmas gifts to computers pump out killer chemicals linked to thousands of deaths because of the filthy fuel they use.
"As ships get bigger, the pollution is getting worse. The most staggering statistic of all is that just 16 of the world's largest ships can produce as much lung-clogging sulphur pollution as all the world's cars."
In today's world ships are used to transfer everything from oil to electronics and as the demand for cheap consumer goods increase, so does the number of ships needed to transport goods around the world.
Thanks to the International Maritime Organization (IMO) rules, the largest ships can each emit as much as 5,000 tons of sulfur in a year -- the same as 50 million typical cars, each emitting an average of 100 grams of sulfur a year.
With an estimated 800 million cars driving around the planet, that means 16 super-ships can emit as much sulphur as the world fleet of cars.
Ship emissions expert James Corbett of the University of Delaware calculates a worldwide death toll of about 64,000 a year. He expects that figure to rise to 87,000 deaths a year by 2012.

Vale de Rodrigo (Évora)
Large prostrated menhir, elongated oval and flat shaped, craved on both sides - primarily composed of circular and subcircularmotifs, serpentine and a possible staff.
The monolith stands along the outer edge of the mound of megalithic tholos Vale de Rodrigo 1, on the East side. In the immediate area are known many funerary monuments and Neolithic/Chalcolithic settlements.
The set is located in a little steep slope exposed to the East and there are no granite outcrops nearby, although they occur less than 1 km away.
This is one of the first standing stones identified in the area of Évora (Leisner, 1944). Their association in space with the dolmen led Georg Leisner regard it as a benchmark indicator and, later, the same association was based on a proposal for a late-Neolithic chronology for the menhirs in general (Gibson et al., 1978).


My paper "Diagrammatic time-local master equation for open quantum systems" is out in Phys Rev A.
We all know that an isolated quantum system is governed by the Schodinger equation. However, in real world, a quantum system is always interacting with the surrounding (possibly macroscopic) environment. Such unavoidable interactions are an essential ingredient that contributes to the fact that we are living in a classical world.
Unfortunately, we typically are not able to follow the dynamics for the full system+environment considering the environment may consist of hundreds of degrees of freedom. In many cases, we are only interested in the primary system instead of the environment, we can focus on the reduced density matrix of the system only. The important question is then: How do we describe the evolution of the reduced density matrices?
In this manuscript, I introduce single Feynman diagrams and rules to directly write down the exact time-local master equation for a general open quantum system interacting with an arbitrary environment.

ACCOUNTING TERMS - ACCOUNTING DICTIONARY - ACCOUNTING GLOSSARY
From the web's #1 provider of financial analysis / ratio analysis
RETAINAGE, in a construction contract, is the money earned by a contractor but not paid to the contractor until the completion of construction or another predetermined date. The retainage is held back as assurance for the quality of the contractors work.
Learn new Accounting Terms
RATIO ANALYSIS involves conversion of financial numbers for a firm into ratios. Ratio analysis allows comparison of one firm to another. Since ratios look at relationships inside the firm, a firm of one size can be directly compared to a second firm (or a collection of firms) which may be larger or smaller or even in a different business. Financial Ratio Analysis is a method of comparison not dependent on the size of either firm. Financial Ratios provide a broader basis for comparison than do raw numbers. In the VentureLine database the comparison is conducted against the industry (SIC Code) in which each particular listing is associated.
NET BOOK VALUE is the difference between total assets (net of accumulated depreciation, depletion, and amortization) and total liabilities of a business enterprise as they appear on the balance sheet (synonymous with Shareholder's Equity); with respect to an intangible asset, it is the capitalized cost of an intangible asset less accumulated amortization as it appears on the books of account of the business enterprise.

The ODPRN has conducted multiple studies that have both informed and evaluated the impact of drug policies in Ontario, and more broadly across Canada. This research includes a wide breadth of work ranging from large drug class reviews to specific rapid response projects resulting from decision makers' pressing initiatives.
Biologic drugs are important treatment options across a wide number of medical conditions, including rheumatic conditions, gastrointestinal disease, and diabetes. Although these drugs have had a measurable impact on patient outcomes, their substantial cost and growth in use threatens the sustainability of public drug programs. A biosimilar biologic drug, or biosimilar, is a drug that is highly similar and has no clinically meaningful differences to an innovator biologic. Biosimilars can also be developed at a lower cost and therefore offer an opportunity to reduce public drug spending.
Unfortunately, biosimilars are underutilized and as a result, public payers in Canada have begun developing policies designed to increase the use of biosimilar drugs. Essential to this work is a better understanding of biologics and biosimilars use across various clinical conditions.
This report describes the current and prospective utilization patterns and expenditures of innovator biologics and biosimilars through the public drug program in Ontario, Canada.
CADTH summarizes this report in "Utilization of Innovator Biologics and Biosimilars for Chronic Inflammatory Diseases in Canada: A Provincial Perspective" and discusses potential implications for decision-makers.


Angel Number 20 Meanings – Why Are You Seeing 20
We all know that numbers are most often used as signs by our guardian angels as they are not able to communicate with us directly. Since the angels don't have a physical form, they look forward to different signs and symbols in order to communicate with humans. As we live in the modern days, we are always surrounded by numbers everywhere.
Meaning of 20 Angel Number – Seeing 20

Terrestria is the plane on which the planet Earth is located.
EDIT: Due to limited Magic information, the best assumption is that planes are individual planets. No other information can be garnered from the true Magic: the Gathering storyline. The best explanation for our universe being in the MtG multiverse is billions of overlays on a gigantic plane, causing each individual cosmic body that exists in real life.
EDIT: The formation of a seperate article, i.e. 'The AoM Multiverse' is suggested.
It is commonly accepted that a plane is not a planet, though in most cases the focus of a plane will take place on a particular planet within this plane. The confusion arises in that most planes are confused with planets, due to the fact that most planes are named after their primary planets.(). Each plane is a seperate 'universe' however, the word itself has the stigmatic effect of only meaning there can be one'verse'. Each'verse' is a plane, within a wider multiverse. This given it means that any number, and any variant of a plane is possible within the multiverse, it can be said that the Magic multiverse contains an infinite number of planes. (). As part of the possibility, and as is used in these storylines, Terrestria is part of this multiverse.

What Is A Telephoto Lens?
What Is A Telephoto Lens?
Widely used among both professional and amateur photographers, telephoto lenses are incredibly popular and can help take your photos to a whole new level.
Telephoto lenses are used in landscape, portrait and sports photography and can enhance the precision of your images. A telephoto lens has a long reach, allowing you to magnify a subject that is several meters away.
Here's what you should know about the benefits and disadvantages of using a camera equipped with a telephoto lens
Telephoto Lens Definition
A telephoto lens is generally defined as any focal length beyond 'normal'. Put simply, this is any focal length beyond around 50mm
Some people confuse telephoto lenses and zoom lenses, usually because most telephoto lenses are of the zoom variety. However, the two are not necessarily related and one can find telephoto lenses in both the Prime and Zoom configurations. You can read more about the differences between zoom and prime lenses here.
What Does A Telephoto Lens Do?
Essentially, a camera equipped with a telephoto lens allows you to capture far-away subjects or simply have a close object fill more of the frame.
Because of this, telephoto lenses are ideal for wildlife photographers or other individuals who cannot move close to their subjects because of physical constraints or safety concerns, likewise event and sports photographers also find them essential. However, these types of lenses also enhance the artistic appeal of a photograph by blurring the background behind your subject, making them very popular for portrait photographers as well.
This is known as'subject isolation' - allowing the photographer to eliminate distractions and ensure that the viewers focus is on their chosen subject. Telephoto lenses excell at this, regardless of where they are applied
Most Commonly Used Telephoto Focal Lengths
Here are the most commonly used telephoto focal lengths:
 - 70–200mm lenses:
 These lenses are ideal for capturing portraiture and events. You can capture a sharp subject with a blurred background so the focus remains on the subject. They are often the 'fastest' (wide aperture) telephoto zoom lenses, making them popular for low light situations like events and indoor sports where a slower zoom lens, or less versatile prime lens, may not be ideal.
 - 100–400mm lenses:
 This lens type allows photographers to accurately capture subjects that are far away. While usually'slower' this lens type is a popular choice for wildlife photographers shooting in bright outdoor situations.
 - 85mm prime lenses:
 These lenses are great for shooting portraits as they have a shallow depth of field. You can easily capture sharp subjects that appear crisp and concise. As a Prime Lens, they are generally some of the fastest lenses you can get, creating fantastic subject isolation under controlled conditions.
 - 135mm prime lenses:
 Similar to 85mm lenses, 135mm have a shallow depth of field that is ideal for shooting portraits, weddings and sporting events. They can be rather large and bulky however, making them less ideal for photographers on-the-go compared to an 85mm
 - Super telephoto prime lenses:
 These types of lenses typically start at around 600mm. While generally large, bulky and slow, they provide a field of view generally un-acheivable with any other lens and are popular for wildlife, deep sky astro and bird photography.
Why Use A Telephoto Lens?
Because a telephoto lens closes the distance between the photographer and the subject, it is perfect for capturing wildlife and sporting events.
Here are the benefits of using a camera equipped with a telephoto lens:
 - Photography subjects are magnified and appear closer to the camera.
 - Telephoto lenses help produced blurred backgrounds, providing excellet subject isolation
 - Telephoto lenses are ideal for creating flattering portraits, generally focal lengths below 50mm can create undesirable distortion which can be unflattering for human subjects. Between 70 - 135mm is often cited as the ideal focal range for flattering portraits.
Best Telephoto Lenses to Choose
There are countless telephoto lenses on the market to choose from. With so many options, how do you know which one to choose? Here are three of the best-selling telephoto lenses available from C.R Kennedy:
Pentax D FA 70-200mm f/2.8 ED Lens
Weather sealed and optically precise, the Pentax D FA 70-200mm f/2.8 ED Lens is one of the best lenses on the market. The Pentax has a bayonet hood and a long petal configuration that snaps easily into position and helps elminate flare without darkening the edges of your image. The hood also comes with a removable section that allows you to enable the filters without removing the lens.
Each lens comes with a clutch mechanism that allows you to manually focus the adjustments. The lens also comes with various modes of operation, including the ability to limit your focus within a selected range, greatly improving the speed and accuracy of the autofocus.
Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens
Another quality lens is the Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens. It's sturdy and durable but has a lightweight construction that allows for flexibility. Designed for mirrorless cameras, it seeks to strike a balance between weight, size and optical performance. The lens also comes with an optional tripod mounting ring, allowing for maximum stability while photographing subjects.
The lens also features excellent optical stabilisation for when you need to go handheld.
Zeiss Batis 135mm f/2.8 Lens
The Zeiss Batis 135mm f/2.8 Lens is very light and compact prime lens, allowing for flexibility without making a compromise on image quality
While many 135mm lenses feature faster apertures, this is often at the expense of size and weight, making this lens ideal for those looking for excellent portraits without sacrificing portability.
If you are ready to purchase a high-quality telephoto lens that is both affordable and functional, look no further than C.R. Kennedy.

This article analyses the history of the Argentina's wealthiest family, the Anchorenas, in the period 1760s- 1940s. What makes these capitalists so peculiar is not only the sheer size of their wealth but also their capacity to adapt to profound changes in the economic and institutional environment. Analysis of the Anchorenas' patterns of investment is placed within a larger debate on the peculiarities of the Argentine economic elite. This article makes use of little-explored sources such as probate records, together with private correspondence. Links between changes in patterns of investment and changes in the economic and institutional environment are explored.
Keywords : Anchorena; Argentina; economic elite; landowners; wealth.

Stoke Newington is a place in the London Borough of Hackney.
Stoke Newington includes Clissold Park, the historic and pretty Abney Park Cemetary, as well as the primary schools St. Mary's School and William Patten, and the secondary school Stoke Newington School.
Stoke Newington has been settled for hundreds of years, with possible Saxon settlements in the area near River Lea. In the middle ages and Tudor times it was a small village on the outskirts of London, frequently visited by wayfarers as a pit stop before journeying North. During the 18th and 19th century, as London expanded, Stoke Newington was absorbed, and was no longer a separate village. Also at this time, many expensive and large houses were built to house London's expanding population of nouveau riche.
During World War II, much of the area was destroyed in the Blitz, and many were made homeless. However luckily, many historic buildings did survive. After the war, the old bomb sites were often transformed into giant housing estates. Initially these were a good idea, but soon after they were seen to be ugly and centres of poverty and crime.
These days, Stoke Newington is a very multicultural area, with large Asian, Turkish and Afro-Carribean communities. There is also a large "green community" which is centred on Church Street and are sometimes seen as new age hippies. They are sometimes nicknamed "Stoke Newington green wellies".
The area continues to be home to many new and emerging communities such as Kosovan.

UK engineers create petrol from air
October 15, 2012
Landmark London conference to discuss 'revolutionary' air capture technology
AFS petrolAir capture technology, which scrubs carbon dioxide (CO2) out of the air, has the potential to become a 'game-changer' in the battle against climate change, and British engineers are at the forefront of making it a reality, the Institution of Mechanical Engineers said today.
The technology will be the subject of a conference – the first of its kind – to be held at the Institution's London headquarters on Tuesday 16 October.
Development of the technology has accelerated over the past few years, and one small British firm has become the first company in the world to demonstrate CO2 air capture as a viable industrial prospect. Air Fuel Synthesis (AFS), based in Stockton-on-Tees, is using air capture to create synthetic petrol using only air and electricity.
AFS recently created its first litres of fuel at the company's Stockton demonstrator plant. The process works as follows:
 - Air is blown into a tower containing a mist of sodium hydroxide which reacts with the carbon dioxide in the air, forming sodium carbonate. Electricity is then passed through the sodium carbonate to release the carbon dioxide, which is stored.
 - A dehumidifier in the tower condenses water from the air. The water is then split into hydrogen and oxygen using an electric current.
 - The carbon dioxide and hydrogen are reacted together to create Syngas, which is then processed to form methanol.
 - The methanol is passed through a gasoline fuel reactor, creating petrol.
The fuel produced can be used in any regular petrol tank and, if renewable energy is used to provide the electricity, the process and end product are completely carbon neutral.
This clean fuel is a direct drop-in replacement fuel for existing vehicles and infrastructure. It can also be used to store intermittent 'wrong-time' or stranded 'wrong-place' energy from renewable sources and has many advantages over biofuels when blended with conventional petrol – a feature that has already attracted the attention of the motorsport industry.
Dr Tim Fox, Head of Energy & Environment at the Institution of Mechanical Engineers, said:
"Air capture technology ultimately has the potential to become a game-changer in our quest to avoid dangerous climate change. What was just a smart idea in the minds of a handful of academics a few years ago is now a proven, engineered method for removing carbon dioxide from the atmosphere and making a useful product. The beauty of petrol from air is that you are effectively recycling CO2 and avoiding further transport emissions.
"While the major recent research advances have largely been made in the US and Canada, it is hugely encouraging that it is British engineers and entrepreneurs who are taking air capture technology out of the lab and using it to create a product. This is particularly poignant given that so much of the world's fossil fuel-based industrial economy of today has its origins in great British engineering innovation from the North East.
"What we need now is the financial and political support to help turn this revolutionary demonstration into a large-scale industrial solution that could make sustainable products, remove and store CO2 from point sources or the atmosphere and set the international carbon price to drive innovation across all clean technologies."
David Still, Chairman of Air Fuel Synthesis, said:
"We are now ready to build the first commercial Air Fuel Synthesis production plant making carbon-neutral petrol. The technology can add to new or existing renewable energy projects, especially where the energy is stranded; where there is a premium for secure liquid fuels for existing vehicles; or for reducing carbon emissions. Demand for specialist high quality low-carbon fuels in motorsports offers a particularly attractive early niche market for investors.
"Further investors and partners will enable us to rapidly commercialise our technologies and help customers address fossil oil price volatility and supply constraints as well as the implications of carbon-driven climate change."
Tuesday's conference, Air Capture: Developing Technologies for Carbon Recycling and Negative Emissions will feature a presentation by Peter Harrison, CEO of Air Fuel Synthesis as well as presentations from some of the world's leading specialists in air capture technology. Highlights include:
 - 9.55am: Keynote presentation: Energy security, economic development and global warming: addressing short and long term challenges

 this is just not a game changer it is the way forward for the human race. In my mind we as a human race are behind in time in terms of development as a 21 century community. We have been destroying our planet for decades drilling, fracking and other methods. Im not an expert but this will clean our air and even tho we putting back CO2 when we re-burn the fuel in effect we will stop adding CO2 to the atmosphere as it a cycle of manufacture.There is still a long way with development but Governments should look into investing money into this, the conspiracy theory it will end west vs east in terms of peace of mind, shift power from countries and the oil companies where there wealth is based on there oil reserve. My opinion forget about attracting interest in oil companies in a sense governments should stick there two fingers up at them and develop self sustaining solution to the fuel market in there country for consumers, there people. This is the first step to sustainable human race.

 This technology could also be a carbon sink by using surplus petrol as a carbon source to grow biomass instead of fueling vehicles. One example might be to identify nitrogen fixing bacteria that utilize petrol as a carbon source and using the recovered biomass as a fertilizer. The possibilities are definitely exciting. Good job!
 4. 5 komentator 23 Oct
 The technology was developed in Germany more than 90 years ago. The carbon source was coal and hydrogen comes from water vapours and the process was known as Fischer-Tropsch reaction (basically CO + H2) of water-gas.
 More information could be find on Wiki. As you see, instead of methanol, the main reaction products are methane (30%) and short alkans and alkenes, alcohols etc.).
 Carbon dioxide reuse
 In 2009, chemists working for the U.S. Navy investigated a modified Fischer–Tropsch process for generating fuels. When hydrogen was combined with the carbon dioxide over a cobalt-based catalyst, the reaction produced mostly methane gas. However, the use of an iron-based catalyst reduced methane production to 30 per cent with the rest being predominantly short-chain, unsaturated hydrocarbons [27] The introduction of ceria to the catalyst's support, functioning as a reverse water gas shift catalyst, furthermore increased the yield of the reaction.[28] The short chain hydrocarbons were successfully upgraded to liquid fuels over solid acid catalysts, such as zeolites.

 This is a great breakthrough towards achieving green-energy system. Exceptionally brilliant ideas!
 6. 3 BCM CEng MIMechE 23 Oct
 It amazes me the IMechE is promoting this. I would be very interested to see some Energy calculations for this process to show just how inefficient and uneconomical it really is.
 The cost and rate of production will never make this viable. The aim after 2 years is to build a plant capable of producing 1 tonne of petrol a day? So about 1400 litres, or enough to fill 20 cars. I would suggest the money used for this venture would be better spend on some engineering education for those who think this is a 'game changer'.
 7. 2 Albert 05 Feb
 it seems that lot of engineers have lost their mind in the search for an impossible solution of a no problem. considering the energy we do use does not came for free from another galaxy but it generated mostly burning fossil fuels, this idea is a nice opportunity to produce more CO2 in the big picture than the CO2 removed with huge costs for the tax payers and at the same time mining more oil, coal and gas. if there is a top ten of the stupid ideas, this is possibly the best.

The development of kaos was fueled by our ambition to mimic natural incremental model development, simplify model reproducibility and collaboration, and automate ML infrastructure deployment in a flexible language-agnostic environment.
Incremental Development is Natural
The typical Data Science workflow is an iterative end-to-end pipeline. It is extremely unlikely that the first inputs result in a final model. Inputs are always changing due to additional training data, an improved model architecture, new tuning parameters, etc... The natural problem solving flow is temporal in nature since we adapt to outcomes - i.e. try X, adapt X, try Y, adapt Y, etc...
Typical tooling ignores the reality of natural temporal incremental development
Reproducibility is Tricky
Data Scientists rely on sampling from large datasets, building interactive visualizations, performing exhaustive statistical analyses, engineering features, developing models, and evaluating model metrics prior to delivery into production. The process is performed in many iterations, which inherently requires tracking which inputs and what processing caused what output (i.e. data provenance).
Tracking provenance explodes when multiple users share multiple models and their respective inputs (e.g. code, environment, data, and parameters).
ML Infrastructure is Tough
Data Scientists use multiple technologies and tools for data processing, algorithm and model development. This mandates the knowledge of what underlying resources are necessary for each task.
Deploying stable elastic infrastructure requires detailed knowledge of authentication, processing, storage and networking (i.e. DevOps).
Flexibility Flexibility Flexibility
Data Scientists require diverse libraries for processing features and/or training models, which is typically linked to a preferred programming language. Tooling flexibility is an absolute necessity to ensure Data Scientists are not hindered throughout their workflow.
A flexible tool must handle different frameworks, packages and languages.

Q. What is the source for the ceremony of placing and dedicating a matzeva, is it an obligation? If the ceremony was postponed (see question above), does the monument have to stay covered until the ceremony?
A. An early source for hakomas hamatzeiva is Yaakov Avinu erecting a monument on Rochel's grave (Bereishis 35: 20). Mishna (Shekalim 2: 5) establishes that obligation and payment dues, to erect a tombstone as asserted by the Tur, Shulchan Aruch (Y. D. 348: 2) and Teshubas Horashbo (56). The Zohar, the Arizal and Sefer Chassidim (738) also place great importance and significance on the monument named nefesh or soul.(See Gesher Hachaim, Kol Bo and others).
Nitei Gavriel (Avelus 2: 67: 3) writes that "after researching all sforim dealing with the traditions of communities, chevros kadishos, avelus and related topics, he could not find a source for the order of the ceremony of hakomas hamatzeiva." He mentions, what is actually said and recited, depends on each community and the sidurim and similar texts they use.
Horav Shlomo Miller's opinion is that the custom that some have to cover the matzeiva with a cloth or similar before the dedication ceremony when it is unveiled, has no basis on Halacha or our traditions.

Tri-Cities Has an Inversion – What the Heck is That? I Found Out!
In normal conditions, hot air close to the ground slowly rises upwards. When a temperature inversion occurs, cooler air gathers near the ground, with a layer of hot air pressing down on top of it. This forces clouds, smog, and pollution to be trapped near the ground. The bottom line is this: We should see more normal weather in the Columbia Basin starting this afternoon and tomorrow. Inversion = pain in the butt!

Innes National Park
Please, login to help us
Hey friend, could you provide us a wikipedia URL with a good description of this protected area?
Please, be sure that you are suggesting an english language wikipedia URL (_URL_....)mark it as wrong
Innes is a national park on the southwest tip of Yorke Peninsula in South Australia (Australia), 160 km west of Adelaide. Innes is the largest area of native vegetation remaining on the Yorke Peninsula, providing habitat for 115 species of conservation significance.
The Narungga people occupied the Yorke Peninsula for thousands of years. They consisted of four clans, the Kurnara of the north, the Windera of the east, the Wari of the West and the Dilpa of the south. European colonisation of the area began in 1846 with sheep grazing near Cape Spencer. Crops were grown on a small scale in the 19th and early 20th century. Innes National Park was named after William Innes, who discovered commercial quantities of gypsum in the early 1900s and founded the mining town of Inneston in 1913, which had a population of around 500 at its peak. Gypsum was mined until 1930 when the great depression made it uneconomical, and in 1970 the town and surrounding land was sold to the South Australian government, creating Innes National Park. Some gypsum mining still continues at nearby Marion Bay.
Some of the buildings at Inneston have been restored and are available as basic hire accommodation. A number of gypsum lakes are with the area of the park, but excluded so they can still be mined for gypsum if required. The park also contains a spectacular rugged coastline which contains the sites of several historic shipwrecks and two lighthouses. The sailing barque Ethel, which ran aground on 2 January 1904, was well-preserved on the beach for many years but little now remains.
Innes National Park was first proclaimed in 1970 when the first Ranger in Charge, Mr Bruce Macreth was assigned to manage the park. Since that time a number of rangers have served the area well including Mr Peter Tomlin (1973-77), Mr Pearce Dougherty (1977-89), Ms Katherine Stephens, Mr Ross Allen, Mr Colin Waters, Mr Bryn Troath, Ms Caroline Paterson and more recently Mr Aaron Smith.
The park headquarters are located in Stenhouse Bay and visitors can obtain information on the park and obtain entry and camping permits at this location.
Innes National Park has 9 camping ground in the park. Pondalowie Campground is the main campground and has fifty sites situated in coastal mallee and sheoak vegetation. Caravans and generators are permitted in the western end of the campground.
Casuarina Campground is a quiet, tranquil campground ideal for families. Eight sites located behind a locked gate require bookings and collection of the gate key from the visitor centre. Access to the beach.
Surfers Campground has ten sites located close to the Pondalowie boardwalk providing access to the popular surf beach and viewing platform.
Shell Beach Campground has eight sites in this shady campground. The lovely Shell Beach is only a short walk from this campsite.
Browns Beach Campground has ten sites nestled amongst natural vegetation and bordered by a steep sand dune. This site is popular with people who come to fish for Australian Salmon at nearby Browns Beach.
Gym Beach Campground, accessed from the Corny Point road, this campground at the northernmost boundary of the park has four sites offering solitude and beach access.
Jollys Beach Campground is a small coastal camping area with approximately four sites. There are no facilities provided.
Stenhouse Bay Campground has twenty-five sites in close proximity to the beach, visitor centre, Innes Trading Post.
Cable Bay Campground has eight sites with easy access to the beach and great views of the offshore islands.
Heritage accommodation is available at the historic lodges at Inneston. In addition, the Stenhouse Bay Hall is available for group bookings (up to 30) and Shepherds Hut at Shell Beach accommodates four people.
The main surf break at Pondalowie is a popular quality wave. It consists of a combination left and right peak that breaks over a reef and snad bottom. The left is good up to about 4'. The right starts to become good from between 3' to 8' plus.
A second smaller right hand reef break known as 'Richards Reef' is located 250 metres further north along the beach. It was named in honour of Mr Richard Thomas a long time local surfer and resident of the area.
Not far from Stenhouse Bay is a break known as 'Chinamans'. This is a powerful and hollow left hand reef break which breaks in shallow water and washes over a rock shelf. It is a high quality wave that is suitable only for skilled surfers and caution should be used when surfing here.

Dr. Giacomo Corneo, Free University of Berlin
Giacomo Corneo joins Brookings scholars and colleagues in a discussion of his research on a "socio-economic equilibrium."
In their collaborative work entitled, A Theory of Symbolic Values, With an Application for Economic Development, Corneo and Jeanne* provide a general framework for thinking about symbolic values in economic settings. They present a theory that addresses the value systems that are consistent with a given resource allocation, and the resource allocations that can be supported by a given value system. This naturally leads to the notion of a "socio-economic equilibrium," the efficiency properties of which can be studied using the standard tools of economic analysis.
In order to illustrate the potential of their theoretical framework for helping understanding key economic issues, Corneo and Jeanne develop three simple models in which people attach a symbolic value to occupations. The models shed some light on the transition from traditional to modern values, the emergence of tolerant societies, and the possibility of failing economic development because of a cultural trap.
*Dr. Oliver Jeanne is a scholar with the International Monetary Fund.

May 25, 2008 Children with autism and ADHD may soon get anxiety relief from a novel "deep-pressure" vest developed by Brian Mullen at the University of Massachusetts Amherst. The vest, which can also be used for adults with mental illness, delivers a "portable hug" called deep pressure touch stimulation (DPTS).
"People with developmental disorders and mental illness are often overwhelmed in everyday environments such as school and the workplace, and solutions available to families and mental health professionals are limited," says Mullen, a doctoral student of mechanical engineering. "This is an alternative therapy that can safely and discreetly provide the treatment they need to function in mainstream society."
To market the vest, Mullen has created a concept business called Therapeutic Systems, which recently won the $50,000 grand prize in the UMass Amherst Technology Innovation Challenge, a competition for the best entrepreneurial technology business plan produced by students, recent alumni and faculty advisors on campus.
Occupational therapists working with children suffering from autism, ADHD and sensory processing disorders have observed that DPTS can increase attention to tasks and reduce anxiety and harmful behaviors by providing different sensory stimuli. DPTS is also part of a growing trend to improve the lives of adults with mental illness by using touch, sound and aroma to influence alertness, attention and their ability to adapt to their surroundings.
Eight clinical studies of the effectiveness and safety of existing weighted blankets and vests that deliver DPTS were conducted by Mullen and his advisor Sundar Krishnamurty, a professor of mechanical and industrial engineering at UMass Amherst. Mullen used that data to design a prototype system for applying DPTS that can be inserted into any commercial vest or jacket with a lining. Initial results of a study with students at UMass Amherst who did not have autism or ADHD showed that participants preferred Mullen's prototype vest, which applies pressure that feels like a firm hug or swaddling, over the current gold standard weighted vest.
Mullen's prototype has several advantages over weighted or elastic garments and toys currently used to apply DPTS in hospitals and schools. "Existing methods provide limited control over the amount of pressure applied and require some oversight by a caregiver," says Mullen. "Their use is also limited because of the lack of literature documenting their safety, and their tendency to make the user stand out in a crowd."
Therapeutic Systems is also starting the initial phase of designing a DPTS blanket to aid with resting and falling asleep. "Falling asleep has been found to be a major problem for many people with mental illness," says Mullen, who adds that an estimated 65 percent of Americans are losing sleep due to stress."

China Welcomes Russian Approval of Kyoto Protocol
BEIJING — China welcomed on Thursday Russia's ratification of the Kyoto climate change protocol and urged countries that have not done so to follow suit.
Russia's upper house of parliament ratified the protocol on Wednesday. The pact aims to limit emissions of greenhouse gases, such as carbon dioxide and methane.
President Vladimir Putin's signature is needed as the final step to kickstart global efforts to try to curb the pace of climate change, which scientists believe will cause more intense storms, severe droughts and rising sea levels.
"It brings hope for the ultimate legalisation of the Kyoto Protocol. China welcomes this move," Foreign Ministry spokeswoman Zhang Qiyue told a news conference. "We hope countries which have not ratified the Kyoto Protocol can approve it like Russia as soon as possible."
China has approved the treaty but has no obligation to cut carbon dioxide emissions during the pact's first phase to 2012.
China, the world's fastest-growing major economy, is also looking at ways to curb greenhouse gas production, including promoting the use of solar panels and wind power. The China Daily said last week the government was drafting a law requiring power companies to buy electricity generated by green energy sources.
Under Kyoto's terms, developed countries responsible for 55 percent of the industrialized world's emissions must ratify the pact for it to come into force and Putin's signature is crucial to meet this condition. If he does, 127 countries would have signed up.
Russia accounts for 17 percent of the world's greenhouse gas emissions.
The United States, by far the world's top polluting and richest country, produces 36 percent. But Washington pulled out of the pact in 2001, saying it would be too expensive for its economy and that it unfairly benefited the developing world because they were not bound by the same reduction targets.
The European Union pushed ahead and put heavy pressure on Moscow to approve it, with Putin finally pledging backing after E.U. leaders gave Russia favorable terms to enter the World Trade Organization.

The Flood of '55
Hurricanes and record rainfalls cause a deadly, devastating flood in August 1955
In August of 1955, Hurricanes Connie and Diane smashed into Connecticut. The storms spawned record rainfalls that transformed placid rivers into killers. During the night of August 18, 1955, and into the next morning, the landscape of nearly half of the state was ravaged and transformed. Dozens were left dead, thousands became homeless and the lives of survivors were forever changed.
Forty years later, Connecticut citizens recounted the most traumatic experience of their lives in The Flood of '55. Underscored by stunning archival film and photographs, this documentary is an unforgettable story of tragedy and heroism; of lives ended and lives renewed.

OUT to sea on the Sunshine Coast, an epic river of flight is wheeling its way south on the great annual mutton bird migration.
But like every great surge of nature, some of these long-distance fliers are starting to drop from the skies and wash up on beaches along Sunshine Coast and Moreton Bay islands.
Biosecurity Queensland test results on several short-tailed shearwaters, otherwise known as mutton birds, which have fallen victim to their non-stop mass migration from Russia to rookeries in Victoria, South Australia and Tasmania, may be available today.
The Department of Environment and Resource Management believes the birds were probably suffering from exhaustion after encountering bad weather along the way.
"A similar event occurred five years ago when short-tailed shearwater birds were found deceased around Fraser Island," a DERM spokesman said.
"Tests at that time confirmed they died from emaciation and starvation as a consequence of the migration."
He said more than a million migratory birds travelled thousands of kilometres to and from Australia each year.
Coast migratory bird enthusiast Jill Dening said mass deaths usually were weather and starvation related and were nothing to be alarmed about.
"They fly by in their millions. It's like a river of birds and it's nature's way of sorting out the strongest," she said.

Chief Seattle's Speech
HistoryLink.org Essay 1427
: Printer-Friendly Format
In addition to his namesake city, Chief Seattle (178?-1866) is best remembered for a speech given, according to pioneer Dr. Henry Smith, on the occasion of an 1854 visit to Seattle of Isaac Stevens (_PHONE_). Stevens was governor and Commissioner of Indian Affairs of Washington Territory. He visited in January and again in March 1854. Chief Seattle's speech went unnoted in the written record until October 29, 1887, when the Seattle Sunday Star published a text reconstructed from admittedly incomplete notes by Dr. Smith.
Smith rendered his memory of Chief Seattle's speech in the rather ornate (to modern ears) English of Victorian oratory. Chief Seattle would have given the speech in the Lushootseed language, which then would have been translated into Chinook Indian trade language, and then into English. Smith's text is a necessarily filtered version of the speech and was certainly embellished by him.
Smith's reconstruction lacks corroboration in the written record, but it is far from implausible. Seattle was well respected among his own people and settlers as a powerful and eloquent orator in his native tongue. It is likely that he was present to meet Governor Stevens in January 1854. Stevens' assistant George Gibbs noted his presence during the March 11, 1854 meeting. Also, there are several accounts in pioneer records of Chief Seattle giving speeches to large crowds.
Frederick James Grant included Smith's text in his 1891 History of Seattle, Washington and Clarence B. Bagley reprinted a slightly altered version in his 1929 History of King County, Washington (Vol. I, pp. 114-116). Most significantly, Bagley appended a new close without explanation or attribution: "Dead -- I say? There is no death. Only a change of worlds."
Bagley's version was reprinted in Roberta Frye Watt's 1931 memoir, Four Wagons West. That same year, John M. Rich used the Bagley text in a popular pamphlet, Chief Seattle's Unanswered Challenge. The speech was revived in the 1960s, notably in articles by William Arrowsmith and Ted Perry (who introduced entirely new material), and these fabricated versions became something of a manifesto for human rights and environmental activists. The evolution of Henry Smith's text is analyzed in detail by Albert Furtwangler in Answering Chief Seattle, published in 1997.
The words themselves remain a powerful, bittersweet plea for respect of Native American rights and environmental values. The version below duplicates Dr. Smith's text as published by the Seattle Sunday Star on October 29, 1887, and as reprinted in Grant's 1891 History of Seattle, Washington. Furtwangler has merged the two texts since the sole copy of the extant newspaper version is damaged. (It now resides in Special Collections at the University of Washington Library.) The speech, along with Henry Smith's account of it, is reproduced here with all original punctuation and spelling.
Henry Smith's Account of Chief Seattle's Speech
"When Governor Stevens first arrived in Seattle and told the natives he had been appointed commissioner of Indian affairs for Washington Territory, they gave him a demonstrative reception in front of Dr. Maynard's office, near the waterfront on Main street. The Bay swarmed with canoes and the shore was lined with a living mass of swaying, writhing, dusky humanity, until old Chief Seattle's trumpet-toned voice rolled over the immense multitude like the startling reveille of a bass drum, when silence became as instantaneous and perfect as that which follows a clap of thunder from a clear sky.
"The governor was then introduced to the native multitude by Dr. Maynard, and at once commenced in a conversational, plain and straightforward style, an explanation of his mission among them, which is too well understood to require recapitulation.
"When he sat down, Chief Seattle arose with all the dignity of a senator who carries the responsibilities of a great nation on his shoulders. Placing one hand on the governor's head, and slowly pointing heavenward with the index finger of the other, he commenced his memorable address in solemn and impressive tones."
[Note: Native Americans believed that Washington was still alive and that King George was the ruler of England.]
Chief Seattle's Speech
"Yonder sky that has wept tears of compassion on our fathers for centuries untold, and which, to us, looks eternal, may change. Today it is fair, tomorrow it may be overcast with clouds. My words are like the stars that never set. What Seattle says, the great chief, Washington … can rely upon, with as much certainty as our pale-face brothers can rely upon the return of the seasons.
"The son [a reference to Terr. Gov. Stevens] of the White Chief says his father sends us greetings of friendship and good will. This is kind, for we know he has little need of our friendship in return, because his people are many. They are like the grass that covers the vast prairies, while my people are few, and resemble the scattering trees of a storm-swept plain.
"The great, and I presume also good, white chief sends us word that he wants to buy our lands but is willing to allow us to reserve enough to live on comfortably. This indeed appears generous, for the red man no longer has rights that he need respect, and the offer may be wise, also, for we are no longer in need of a great country.
There Was A Time
"When our people covered the whole land, as the waves of a wind-ruffled sea cover its shell-paved floor. But that time has long since passed away with the greatness of tribes now almost forgotten. I will not mourn over our untimely decay, nor reproach my pale-face brothers for hastening it, for we, too, may have been somewhat to blame.
"When our young men grow angry at some real or imaginary wrong, and disfigure their faces with black paint, their hearts, also, are disfigured and turn black, and then their cruelty is relentless and knows no bounds, and our old men are not able to restrain them.
"But let us hope that hostilities between the red-man and his pale-face brothers may never return. We would have everything to lose and nothing to gain.
"True it is, that revenge, with our young braves, is considered gain, even at the cost of their own lives, but old men who stay at home in times of war, and old women, who have sons to lose, know better.
"Our great father Washington, for I presume he is now our father, as well as yours, since George [a reference to King George III, i.e., Great Britain] has moved his boundaries to the north; our great and good father, I say, sends us word by his son, who, no doubt, is a great chief among his people, that if we do as he desires, he will protect us. His brave armies will be to us a bristling wall of strength, and his great ships of war will fill our harbors so that our ancient enemies far to the northward, the Simsiams [Tsimshian] and Hydas [Haidas], will no longer frighten our women and old men. Then he will be our father and we will be his children.
But Can This Ever Be?
"Your God loves your people and hates mine; he folds his strong arms lovingly around the white man and leads him as a father leads his infant son, but he has forsaken his red children; he makes your people wax strong every day, and soon they will fill the land; while my people are ebbing away like a fast-receding tide, that will never flow again. The white man's God cannot love his red children or he would protect them. They seem to be orphans who can look nowhere for help. How then can we become brothers? How can your father become our father and bring us prosperity and awaken in us dreams of returning greatness?
"Your God seems to us to be partial. He came to the white man. We never saw Him; never even heard His voice; He gave the white man laws but He had no word for His red children whose teeming millions filled this vast continent as the stars fill the firmament. No, we are two distinct races and must remain ever so. There is little in common between us. The ashes of our ancestors are sacred and their final restingplace is hallowed ground, while you wander away from the tombs of your fathers seemingly without regret.
"Your religion was written on tables of stone by the iron finger of an angry God, lest you might forget it. The red man could never remember nor comprehend it.
"Our religion is the traditions of our ancestors, the dreams of our old men, given them by the great Spirit, and the visions of our sachems, and is written in the hearts of our people.
"Your dead cease to love you and the homes of their nativity as soon as they pass the portals of the tomb. They wander far off beyond the stars, are soon forgotten, and never return. Our dead never forget the beautiful world that gave them being. They still love its winding rivers, its great mountains and its sequestered vales, and they ever yearn in tenderest affection over the lonely hearted living and often return to visit and comfort them.
"Day and night cannot dwell together. The red man has ever fled the approach of the white man, as the changing mists on the mountain side flee before the

Although Tunisia has enacted several laws pertaining to environmental protection, enforcement of environmental legislation has not been consistent until recently, due both to the lack of staff and resources. In addition, the legal instruments available in the past were not highly effective.
The creation of the National Environmental Protection Agency (ANPE) in 1988, however, led to the development of a National Action Plan for the Environment (NAPE), which attempts to draw together existing environmental legislation and programs and to provide a strategy for natural resource conservation, pollution control and land-use management. To that end, article 8 of Air Pollution and Noise Emissions Law No. 88-91 dictates that any industrial, agricultural or commercial establishment as well as any individual or corporate entity carrying out activity that may cause pollution to the environment, is obliged to eliminate or to reduce discharges and, eventually, to recycle rejected matter. The ANPE may initiate legal proceedings against violators or reach a compromise with the polluting entity.
Legislation pertaining to environmental protection includes the Wildlife Protection Law No. 88-20; the Water Pollution Law No. 75-16; and the Marine Pollution Law No. 75-16.
In addition, Tunisia is a member of ISO. In June, 1997, the Technical Committee for the Elaboration of Standards adopted the ISO 14,000 Series relating to industrial atmospheric emission standards.
Tunisia has entered into several international conventions and agreements dealing with environmental problems and aspects, including:
- Convention of the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons, and on Their Destruction;
- Convention on International Trade in Endangered Species of Wild Fauna and Flora;
- Convention for the Protection of the Mediterranean Sea Against Pollution;
- Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space and Under Water; and
- International Convention Relating to Intervention on the High Seas in Cases of Oil Pollution Casualties.

I am getting this error when I GetById() on an entity and then set the collection of child entities to my new list which comes from the MVC view.
I don't quite understand this line:
Why would I change the relationship between 2 entities? It should remain the same throughout the lifetime of the whole application.
The code the exception occurs on is simple assigning modified child classes in a collection to the existing parent class. This would hopefully cater for removal of child classes, addition of new ones and modifications. I would have thought Entity Framework handles this.
The lines of code can be distilled to:
var thisParent = _repo.GetById(1);
thisParent.ChildItems = modifiedParent.ChildItems();

You should delete old child items thisParent.ChildItems one by one manually. Entity Framework doesn't do that for you. It finally cannot decide what you want to do with the old child items - if you want to throw them away or if you want to keep and assign them to other parent entities. You must tell Entity Framework your decision. But one of these two decisions you HAVE to make since the child entities cannot live alone without a reference to any parent in the database (due to the foreign key constraint). That's basically what the exception says.
What I would do if child items could be added, updated and deleted:
public void UpdateEntity(ParentItem parent)
 // Load original parent including the child item collection
 var originalParent = _dbContext.ParentItems
 .Where(p => p.ID == parent.ID)
 .Include(p => p.ChildItems)
 // We assume that the parent is still in the DB and don't check for null
 // Update scalar properties of parent,
 // can be omitted if we don't expect changes of the scalar properties
 var parentEntry = _dbContext.Entry(originalParent);
 foreach (var childItem in parent.ChildItems)
 var originalChildItem = originalParent.ChildItems
 .Where(c => c.ID == childItem.ID && c.ID!= 0)
 // Is original child item with same ID in DB?
 if (originalChildItem!= null)
 // Yes -> Update scalar properties of child item
 var childEntry = _dbContext.Entry(originalChildItem);
 // No -> It's a new child item -> Insert
 childItem.ID = 0;
 // Don't consider the child items we have just added above.
 // (We need to make a copy of the list by using.ToList() because
 // _dbContext.ChildItems.Remove in this loop does not only delete
 // from the context but also from the child collection. Without making
 // the copy we would modify the collection we are just interating
 // through - which is forbidden and would lead to an exception.)
 foreach (var originalChildItem in
 originalParent.ChildItems.Where(c => c.ID!= 0).ToList())
 // Are there child items in the DB which are NOT in the
 // new child item collection anymore?
 if (!parent.ChildItems.Any(c => c.ID == originalChildItem.ID))
 // Yes -> It's a deleted child item -> Delete
Note: This is not tested. It's assuming that the child item collection is of type ICollection. (I usually have IList and then the code looks a bit other.) I've also stripped away all repository abstractions to keep it simple.
I don't know if that is a good solution but I believe that some kind of hard work along these lines must be done to take care of all kinds of changes in the navigation collection. I would be happy as well to see an easier way.

So what if some are only changed? Does that mean I still have to remove them and add them again? – jaffa Apr 4 '11 at 17:10
_USER_: No, you can also update existing items of course. I've added an example how I would probably update the child collection, see Edit section above. – Slauma Apr 4 '11 at 18:33
_USER_: Lol, if I knew that you are going to modify your answer I would not write my answer... – Ladislav Mrnka Apr 4 '11 at 19:53
_USER_: No, no, I am glad that you wrote your own answer. Now at least I know that it's not complete nonsense and much too complicated what I did above. – Slauma Apr 4 '11 at 20:27
I would add a condition when retrieving the originalChildItem in the foreach:...Where(c => c.ID == childItem.ID && c.ID!= 0) otherwise it will return the newly added children if the childItem.ID == 0. – perfect_element Mar 1 at 17:02
This is a very big problem. What actually happens in your code is this:
 - You load Parent from the database and get an attached entity
 - You replace its child collection with new collection of detached children
 - You save changes but during this operation all children are considered as added becasue EF didn't now about them till this time. So EF tries to set null to foreign key of old children and insert all new children => duplicate rows.
Now the solution really depends on what you want to do and how would you like to do it?
If you are using ASP.NET MVC you can try to use UpdateModel or TryUpdateModel.
If you want just update existing children manually, you can simply do something like:
foreach (var child in modifiedParent.ChildItems)
 context.Entry(child).State = EntityState.Modified;
Attaching is actually not needed (setting the state to Modified will also attach the entity) but I like it because it makes the process more obvious.
If you want to modify existing, delete existing and insert new childs you must do something like:
var parent = context.Parents.GetById(1); // Make sure that childs are loaded as well
foreach(var child in modifiedParent.ChildItems)
 var attachedChild = FindChild(parent, child.Id);
 if (attachedChild!= null)
 // Existing child - apply new values
 // New child
 // Don't insert original object. It will attach whole detached graph
// Now you must delete all entities present in parent.ChildItems but missing
// in modifiedParent.ChildItems
// ToList should make copy of the collection because we can't modify collection
// iterated by foreach
foreach(var child in parent.ChildItems.ToList())
 var detachedChild = FindChild(modifiedParent, child.Id);
 if (detachedChild == null)
share|improve this answer
But there is your interesting remark about using.Clone(). Do you have the case in mind that a ChildItem has other sub-child navigation properties? But in that case, wouldn't we want that the whole sub-graph is attached to the context since we would expect that all the sub-childs are new objects if the child itself is new? (Well, might be different from model to model, but let's assume the case that the sub-childs are "dependent" from the child like the childs are dependent from the parent.) – Slauma Apr 4 '11 at 20:35
It would probably require "smart" clone. – Ladislav Mrnka Apr 4 '11 at 20:39
What if you don't want to have a Child's collection in your context? _URL_ – kirsten g Nov 27 '13 at 4:55
I've no idea why the other two answers are so popular!
I believe you were right in assuming the ORM framework should handle it - after all, that is what it promises to deliver. Otherwise your domain model gets corrupted by persistence concerns. NHibernate manages this happily if you setup the cascade settings correctly. In Entity Framework it is also possible, they just expect you to follow better standards when setting up your database model, especially when they have to infer what cascading should be done:
You have to define the parent - child relationship correctly by using an "identifying relationship".
If you do this, Entity Framework knows the child object is identified by the parent, and therefore it must be a "cascade-delete-orphans" situation.
Other than the above, you might need to (from NHibernate experience)
instead of replacing the list entirely.
_USER_'s comment reminded me that detached entities are another part of the overall problem. To solve that, you can take the approach of using a custom model binder that constructs your models by attempting to load it from the context. This blog post shows an example of what I mean.
share|improve this answer
Setup as identifying relationship won't help here because the scenario in the question has to deal with detached entities ("my new list which comes from the MVC view"). You still have to load the original children from the DB, find the removed items in that collection based on the detached collection and then remove from the DB. The only difference is that with an identifying relationship you can call parent.ChildItems.Remove instead of _dbContext.ChildItems.Remove. There is still (EF <= 6) no built-in support from EF to avoid lengthy code like the one in the other answers. – Slauma May 7 '13 at 21:39
I understand your point. However, I believe with a custom model binder that loads the entity

4 Spooky Ways the Moon Can Affect Your Body

4 Spooky Ways the Moon Can Affect Your Body
"On October 27, the Taurus full moon shines its light on your third house of communication, helping you refine your message and million-dollar ideas. This full moon is the last of three consecutive supermoons, so its effect will be potent..."
If you're a loyal horoscope follower, you know that if the moon makes an appearance in your monthly reading, you're in for something BIG. 'Mercury in retrograde' might be the trendiest of astrological phases right now—seems like we can blame everything from breaking a fingernail to breaking up with a significant other on the problematic planetary alignment. But before Mercury, there was the moon, and for thousands of years folklore and mythology has blamed its lunar orbit for the strange and unexplainable.
Although astrologists can't officially blame our emotions on the moon (sorry, mystic mamas, this myth has been debunked by science!), there are actually more than a few ways that the moon can totally mess with you. Don't worry, we're not talking full-on werewolf effect, but read on for the crazy ways the moon influences our lives.
It can control your cycle
In a study published in the Acta Obstetricia et Gynecologica Scandinavicaresearchers looked at the menstrual cycles of 826 healthy women. During the full moon, 28 percent of women started their cycle, compared to the proportion of 8 to 12 percent of women who started during other phases of the month. The study shows a strong link to the lunar cycle and women's menstrual cycles, but researchers are unclear as to why exactly the moon influences hormones.
It protects your heart
Despite what horoscopes say about each sign's love life during the full moon, it might be a good thing for your heart muscle. Researchers from Central Hospital of Augsburg, Germany, studied 16,000 cardiac patients and found that there was a significant drop in heart attacks in the three days after a new moon. Why? It could have something to do with gravity. The gravitational pull from the moon and from Earth is the strongest during the full moon and new moons, and this could have a beneficial effect on circulation and heart rates.
It disrupts your sleep
Feeling a little more tired this morning? Blame it on the full moon. Swiss sleep scientists studied 31 subjects over a full lunar cycle and found that during a full moon it took longer to fall asleep, they slept 20 minutes less, and had 30 percent less time in a deep sleep mode.
If you're imagining it's harder to fall asleep simply because of the extra brightness of a full moon, think again: Researchers' sleep studies took place in rooms with zero exposure to outside light. No doors, no windows, and definitely no moonlight. This fact lead researchers to suggest that in addition to a circadian rhythm, humans also have a circalunar rhythm. But its effect on our health and sleep habits couldn't be explained. Want to fall asleep a little more easily when the full moon appears? Try a melatonin supplement before bed!
It can help you recover more quickly
Going in for a medical procedure? Plan it around the full moon. According to a study done at Rhode Island Hospital, patients that had surgery during the waning full moon were less likely to have complications and were more likely to survive their procedures. Plus, if surgery was completed during the full moon patients stayed in the hospital an average of 10 days, versus during the rest of the month when patients who had the same procedures took 14 days to recover.
Although the term lunatic originates from the Latin root for moon, luna, there's no certain evidence that the moon truly affects our emotions or psychological health. But it's undeniable that the orbiting planet plays a role in our daily lives and health—it's reasonable to assume that if the moon can affect our hearts and circulation, sleep cycles, menstrual cycles and hormones, and the way our bodies regenerate, then maybe it might have an effect on our emotions, too.

 If the moon has all these effects on us, then why not our emotions?! I've ALWAYS realized that my emotions are affected by the full moon. I feel and act way more stable now that it's not the full moon anymore. Hello...moods and hormones are SO interrelated!


Introduction to IP Conflict Prevention of VigorSwitch
Nowadays, it is common that a company network consists of not only servers and PC, but also IoT devices, printer, IP cameras, and a lot more. Stability would always be the top priority, and IP conflict is one of the causes of unstable connections. In the past, the network administrator may need to take a long time to find conflict sources from the big network.
VigorSwitch supports IP Conflict Prevention (ICP) since firmware version 2.4.0. It helps the administrator to find out the conflicting port and IP and take action quickly. This article introduces ICP and demonstrates how to use it on VigorSwitch.
an illustration of network topology
ICP on Multiple Switches
ICP takes the advantages when there are multiple switches on the network, even if not all the switches support ICP. The edge switch can be other brands that you already have, and ICP would still work partially.
For example:
PC4 conflicts PC1: PC4 can't go through core switch, but PC4 still can access other hosts within edge switch.
PC2 conflict PC1: PC2 will be locked. It's because PC1 is configured to have the higher priority of using the IP.
an illustration of network topology
Conflict Warning
When IP conflict happens, ICP shows the conflict status on the GUI like below, so that the network administrator could be aware of where the problems are.
a screenshot of VigorSwitch
How to Set up ICP?
Quick Start Wizard will be convenient and easy way to set up.
a screenshot of VigorSwitch
1. In the Quick Start Wizard, first select a port to which DHCP server is connecting.
a screenshot of VigorSwitch
2. VigorSwitch will conduct a preliminary detection of the environment and show the port type. If the port is incorrect, click on the port to change the port type to the correct one
 1. DHCP server: Tell the Switch which port the DHCP Offer will come from so it can block illegal DHCP Offers.
 2. DHCP Client: The Switch automatically learn the DHCP offer/ack to each port, and dynamically add/remove the IP into the table, thus to protect LAN clients who receive IP from DHCP server.
 3. Static Binding: For connecting to a device with a static IP. The switch memorizes the "static IP/port" combination and protects LAN clients on the list.
 4. Multiple Hosts: For connecting to an AP or a switch, all the IP behind the port will all be protected. If there's conflict in this port, conflict status will show the port conflict itself.
 5. LAG:Accept multiple ports using same IP address without looping and conflicting
 6. Multiple Host with DHCP Server:Accept several IP addresses to a single port; these IP addresses include DHCP Clients or Static Binding Clients, and a host register to be a legal DHCP Server and gain protection.
an illustration of network topology
3. The switch will detect your network, and showing the hosts table. Remember to put the correct information on it.
a screenshot of VigorSwitch
4. Enable ICP, then ICP will be affected immediately.
a screenshot of VigorSwitch
1. If I have multiple switches in my network, what is the sequence to enable ICP on different switch layer?
We recommend to set the port type first (1-3 step on Wizard), then enable ICP on each layer.
2. We can set up the Mail Alert to let VigorSwitch send the message to notify the network administrator which port conflicts
3. When IP Conflict Prevention is processing, IP conflict detection can not be enabled.
