Preamble

The two main types of superconducting materials are known as type-I and type-II superconductors, and their properties will be discussed in the remainder of this course. All of the pure elemental superconductors are type-I, with the exception of niobium, vanadium and technetium. The discussion of the effects of magnetic fields and currents on superconductors earlier in this course has been confined to thin cylinders of type-I materials like lead or tin in a parallel magnet

Surgical Navigation in Orthopaedic Oncology: Promise or Peril?
Orthopaedic oncologists help care for patients with tumors of the bones and soft tissues, which are generally called sarcomas. Surgical treatment often consists of accurate tumor removal with an appropriate margin of uninvolved tissue, followed by a reconstruction that maximizes patient function. So-called 'surgical navigation', these are developing technologies which allow 3D intraoperative localization, based on advanced imaging studies. In this Grand Rounds, orthopaedic surgeons from the Uni

During this course, we will study the similarities between cancer and normal development to understand how tumors co-opt normal developmental processes to facilitate cancer initiation, maintenance and progression. We will examine critical signaling pathways that govern these processes and, importantly, how some of these pathways hold promise as therapeutic targets for cancer treatment. We will discuss how future treatments might be personalized to target cancer cells in specific patients. We wil

4.1.1 Identifying the pregnacy

Our description of the developing embryo has, so to speak, detached it from its mother. But we should remember that on the other end of the placenta is a woman whose reaction to her pregnancy may lie almost anywhere in the scale of human emotion, and whose behaviour during her pregnancy will have an enormous effect on its outcome. This section attempts to look at the pregnancy from the mother's point of view. Of course, it cannot possibly be applicable to all women in all pregna

Why create the EU?

All the member states of the EU have declared a belief in certain fundamental values and aims. Those fundamental values include the securing of lasting peace, unity, equality, freedom, security, solidarity, democracy and the rule of law (Article 6 [1] TEU). Remember that the creation and growth of the EU, like the European Convention on Human Rights, was achieved through the efforts of individuals and states that experienced the horrors and economic aftermath of the Second World War.

9.1 Overview

There are over 139,000 social service workers in Scotland, providing care and support to some of the most vulnerable sections of society. The Scottish Social Services Council is responsible for specifying the standards to which social service workers involved in providing or delivering social work, social care services, early education and child care will work.

In this section of the OpenLearn Scotland collection, we look at issues relating to social care by focusing on three particular
