1.8 Key points about vitamins Vitamins A, D, E and K are fat-soluble; the remainder are water-soluble. Adequate amounts of vitamins are required, many on a regular basis, though some can be stored. A balanced diet should provide the necessary amounts of vitamins, but people on a restricted diet need to take particular care to ensure an adequate intake of all of them. Deficiency diseases can occur when vitamins are absent or in short supply.
Replacement anxiety: White supremacist terrorism The terrorist attack in Christchurch, New Zealand, has left 50 people dead and a lot of unanswered questions. How big a threat are violent white supremacists? We take a look at a network of museums in China trying to commemorate that country’s murderous experience in the 20th century without offending the Communist Party. And our San Francisco correspondent goes in pursuit of free stuff - a lot of it-in the Bay Area.
17.436 Territorial Conflict (MIT)
This graduate seminar introduces an emerging research program within International Relations on territorial conflict. While scholars have recognized that territory has been one of the most frequent issues over which states go to war, territorial conflicts have only recently become the subject of systematic study. This course will examine why territorial conflicts arise in the first place, why some of these conflicts escalate to high levels of violence and why other territorial disputes reach set
Analyse et prise en compte des contraintes didactiques et informatiques dans la conception et le dé
This paper shows the didactical and computational constraints in the design of software for mathematical proof in geometry: Cabri-Euclide. The earliest constraint is to produce software for mathematical proof without has the previous solutions concerning the problem. Cabri-Euclide is a microworld, Thus, the essential is that the system have to verify a local coherence, and not to designate a global automatic deduction.

6.823 Computer System Architecture (MIT)
6.823 is a course in the department's "Computer Systems and Architecture" concentration. 6.823 is a study of the evolution of computer architecture and the factors influencing the design of hardware and software elements of computer systems. Topics may include: instruction set design; processor micro-architecture and pipelining; cache and virtual memory organizations; protection and sharing; I/O and interrupts; in-order and out-of-order superscalar architectures; VLIW machines; vector
Line Integral - Green's Theorem
This is a short introduction to Green's Theorem which concerns turning a closed loop integral into a double integral given certain conditions.

This case study describes the use of pod casts to support and enhance student decision making in the development and running of a new simulated company using business simulation software
1.3.6 Journals Journals and articles written by academics or experts are an excellent source of information. Journals are usually published monthly or quarterly, and contain a selection of articles providing details of recent research. Often they will also contain reviews of relevant books. They are usually published more quickly than books, and so are often more up to date. To access content of journals, most publishers require a subscription. There are, however, some journals which you can freely ac
Defining City Regions
The concept of 'City Regions' has been picked up by political leaders in the UK at both a national and local level. The concept has been used as the basis for a number of policy initiatives, but what lies behind the idea of a 'City Region' and what are the implications for governance and local identity if we start to think in these terms.
Professor Colin Crouch, Professor of Governance and Public Management at Warwick Business School, has studied City Regions for the OECD.

2.2.2 Precision Measuring the same sample should give the same result every time if the equipment is precise. In practice, the information displayed by a measuring device can depend on several factors (such as temperature and humidity) and can drift slightly over time. Nevertheless, during the time it takes to complete a measurement sequence, all measurements ought to remain within a specified, small margin of error, often marked on the equipment. We will see later on, in Author(s):
1.1.1 Assessing your current level of knowledge If you explore all the resources and activities in this course, you might need to allow between two and nine hours to complete it. Before you read this guide, why not use the self-assessment questions on the next screen to rate your current level of knowledge? Print or save these questions and for each question, mark the most appropriate number on the scale. When you have finished, you can review your answers. A score of three or less might indicate a gap in your knowledg

For me, thinking about the use of models convinces me of some of the benefits of ‘problematising’ science – as we've been doing in the commentary so far. Indeed, my feeling is that using models reflects something more general about how scientific understanding is built up.

You will find that these concepts are open to a range of possible definitions, and that the functions of social work and law can change depending on the practice context. Their meaning is also affected by the perspective from which they are viewed, for example, the service user's experience of social work and law will not always match the expectations of the professional, or the perceptions of the general p
