2.1 The primary structure of nucleic acids

We now know the detail of the order of individual bases, i.e. the genome sequence, of many of the organisms listed in Table 1. In Section 2 we will focus on the structures of nucleic acids within the cell, and we will start this discussion by outlining some of the general principles that apply to all nucleic acid structures

Analysing the significance of problem solving expertise and computational tool proficiency in design
This paper presents a pilot study to analyze the role of problem solving expertise (PSE) and computational tool proficiency (CTP) of expert and novice architects in the ideation process within a distributed cognition environment. To analyze PSE, we studied the frequency of occurrence of unique problem solving tasks per limited commitment mode (LCM) revisit. We also devised a quantitative measure for analyzing CTP based on the frequency of unique and normally distributed modeling activities per d

1.3.1 Why are cells different?

Now let us go on with our story and assume that we have decided the time is right to have a baby. The primary requirement for conception is that healthy gametes should be produced. We shall therefore look first at how gametes are made, and then examine some of the factors affecting their quality. But we must start with an explanation of what gametes are, and what sets them apart from other kinds of cell. In other words, what makes gametes special? Gametes are the cells that fuse to form a new

2.5 Critical current

The current density for a steady current flowing along a wire in its normal state is essentially uniform over its cross-section. A consequence of this is that the magnetic field strength B within a wire of radius a, carrying current I, increases linearly with distance from the centre of the wire, and reaches a maximum value of μ0I / 2Author(s): The Open University

Introduction

We are used to seeing spectacular astronomical images in the press and on the internet. This course gives an in-depth introduction to two of the most important instruments used to create these images and explore the science behind them – telescopes and spectographs.

This course is drawn from the preparatory work for the practical residential school at the Observatori Astronomic de Mallorca. The course image shows a student at work in one of the telescope domes at the Observatori.

3.5 Summary of Section 3

Behavioural mechanisms for reducing water loss are integrated with physiology. While Dipodomys rests in a cool burrow, the nasal counter-current heat exchanger cools exhaled air, conserving water vapour evaporated from respiratory surfaces. Long loops of Henle operate as counter-current multipliers, producing highly concentrated urine. Desert foxes use panting for evaporative cooling, but high rates of evaporative water loss cannot be sustained; hence the crucial importance of dens for

2 Solar thermal energy

Solar heating of trapped air, water and solids has been used for centuries, but modern architectural design can enhance all three effects for space heating, hot water supply and heat storage. Such passive solar heating relies on short-wave radiation being absorbed by materials so that they heat up and then slowly re-emit long-wave radiation. The most obvious example is inside a greenhouse, where solar radiation that passes through the glass heats the inside air to temperatures well abo

Space Station Live: The Secrets of Bones
NASA Commentator Dan Huot talks with Dr. Paola Divieti Pajevic, the principal investigator of the Osteo-4 experiment which is arriving at the International Space Station on the new Dragon cargo ship, about her research into the function of osteocytes, the cells in the bones which sense mechanical forces. The experiment will study the function and behavior of those cells in space to try to determine why astronauts who spend long periods in space lose bone density; the findings may have also appl
