The stem, black and cereal rusts are caused by the fungus Puccinia graminis and are a significant disease affecting cereal crops. Crop species which are affected by the disease include bread wheat, durum wheat, barley and triticale. An epidemic of stem rust on wheat caused by race TTKSK (e.g. isolate Ug99) is currently spreading across Africa, Asia and the Middle East and is causing major concern due to the large numbers of people dependent on wheat for sustenance. The strain was named after the country where it was identified (Uganda) and the year of its discovery (1999). It spread to Kenya, then Ethiopia, Sudan and Yemen, and is becoming more virulent as it spreads. Scientists are working on breeding strains of wheat that are resistant to UG99. However, wheat is grown in a broad range of environments. This means that breeding programs would have extensive work remaining to get resistance into regionally adapted germplasms even after resistance is identified.
There is considerable genetic diversity within the species P. graminis, and several special forms, forma specialis, which vary in host range have been identified.

Rust is an iron oxide, usually red oxide formed by the redox reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances. Rust consists of hydrated iron(III) oxides Fe2O3·nH2O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH)3).
Given sufficient time, oxygen, and water, any iron mass will eventually convert entirely to rust and disintegrate. Surface rust is flaky and friable, and it provides no protection to the underlying iron, unlike the formation of patina on copper surfaces. Rusting is the common term for corrosion of iron and its alloys, such as steel. Many other metals undergo equivalent corrosion, but the resulting oxides are not commonly called rust.
Other forms of rust exist, like the result of reactions between iron and chloride in an environment deprived of oxygen. Rebar used in underwater concrete pillars ,which generates green rust, is an example.
A quick overview of what STEM education is and why it's important.
What is STEM? It's the acronym for science, technology, engineering and mathematics. But while kindergarten through 12th grade education usually focuses on science or mathematics in isolation, all four of these disciplines are closely intertwined in the real world. Imagine if K-12 students were taught in ways that highlighted these connections, making their education more relevant to their lives and opening doors to new and exciting careers. Watch this video and tell us what you think!

Professor Roni Ellington has served on the faculty at Morgan State University since 2006. Her work focuses on mathematics education. Research interests include understanding the experiences of high achieving mathematics students, STEM education, and teacher professional development. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regula...
STEM is a nationwide initiative aimed at better equipping kids for the future. STEM stands for science, technology, engineering, and math. But STEM is more than just an acronym, its a step forward. In today's society, United States companies are forced to outsource high level jobs because Americans aren't qualified. STEM is trying to fix this problem by getting kids involved in these fields in early education.

A STEM career video produced by Rolls-Royce. For more information about this video please visit http://www.wherestemcantakeyou.co.uk Teachers should also have a look at our annual STEM careers conference: https://www.sciencelearningcentres.org.uk/cpd/ondemand/faa63c40-be7f-46cc-a5e8-42e9d981ad13/promoting-stem-careers-in-your-classroom-engage-enrich-enthuse/ Which will provide ideas and inspiration on delivering effective careers education and guidance. Corporations interested in getting involved with educating teachers about what STEM graduates in their organisations actually do, should get involved with our Teacher Industry Partnership Scheme https://www.sciencelearningcentres.org.uk/consortia/national/teacher-industrial-partners-scheme/

This is a solo survival of the new update. The component system, base building, pvp and more! For the first time in recent Rust history, all items are able to be crafted by anyone from the get go. There is no more learning blueprints; no more unlocking items with XP. In fact, there are no more levels, XP, or blueprints at all. Everyone can craft anything, at any time, provided they have the required components.
