2.3 Environmental regulation of breeding

As pointed out in Section 1.1, primary plant productivity occurs for only a few months in the summer, so the reproductive physiology of most arctic animals, particularly herbivorous species, is tightly synchronized with the seasons. On Svalbard (Figure 2b), more than 90% of the reindeer fawns are born in the first week of J

2.2 Receptor specificity

Binding of an extracellular signal to its receptor involves the same type of interactions as those between an enzyme and its substrate. Receptor specificity depends on the binding affinity between the ligand and the binding site on the receptor. The dissociation constant (KD) describes the affinity between receptors and their ligands.

Proteins can be thought of as consisting of various domains, and the different combinations of structural motifs in the extracellular re

3.1 Market access: expectations unfulfilled

A key objective of developing countries in trade liberalisation negotiations is access for their exports to the markets of developed countries. However, the rules have been played out by developed countries in ways that block the hoped-for rise in exports.

HST.542J Quantitative Physiology: Organ Transport Systems (MIT)
This course elaborates on the application of the principles of energy and mass flow to major human organ systems. It discusses mechanisms of regulation and homeostasis. It also discusses anatomical, physiological, and pathophysiological features of the cardiovascular, respiratory, and renal systems. There is emphasis on those systems, features, and devices that are most illuminated by the methods of physical sciences.

2.3.2 Fast breeder reactors

If fast neutrons produced in the chain reactions are not moderated or absorbed, the rate of conversion of uranium-238 into plutonium-239 (Equation 3) can exceed the fission rate of plutonium-239. Reactors that use fast neutrons in this way are called fast breeder reactors.

Their main fuel is

3.2 Uranium occurrence and ore deposits

In igneous rocks, uranium is more abundant in granites (~3.5 ppm) than in basalts (~1 ppm). The large size of the uranium atom prevents it from easily entering the structures of common rock-forming minerals, so it is an incompatible element that tends to remain in magmas until a late stage of crystallisation, when it enters minor minerals, or even the uranium oxide, uraninite (UO2). In suitable circumstances, following fractional crystallisation of uranium-rich granitic magm

Learning outcomes

After studying this course, you should be able to:

  • explain the meanings of the newly defined (emboldened) terms and symbols, and use them appropriately

  • distinguish between perfect conduction and perfect diamagnetism, and give a qualitative description of the Meissner effect

  • explain how observation of a persistent current can be used to estimate an upper limit on the resistivity of a superconductor, and perform calculations related to such estimates<

7.8 Summary of Section 7

This section has sought to illustrate the formation of connections between neurons and their targets by exploring a few examples. The picture that emerges is one of cells at different stages of development subjected to a vast array of signals. These signals are the medium through which environmental factors exert their effects. To some of these signals, some cells respond; to other signals, other cells respond. What a cell, a neuroblast, a growth cone actually does is dependent on the combina
