8.3 The AND operation

The AND operation combines two binary words bit by bit according to the rules

  • 0 AND 0 = 0

  • 0 AND 1 = 0

  • 1 AND 0 = 0

  • 1 AND 1 = 1

In other words, only when both bits are 1 is the result 1. You may find it helpful to think of it this way: when one bit is one and the other bit is 1 the result is 1.

3.2 Some general properties of galaxies

Firstly, we note that galaxies tend to occur in clusters rather than singly. The mutual gravitational attraction of galaxies naturally tends to hold them on paths that remain close to each other. Typically a cluster contains tens or hundreds of galaxies. There are, however, large clusters with thousands of galaxies, and there are some solitary galaxies. Our own Galaxy is a member of a smallish cluster of about 36 galaxies called the Local Group (see Author(s): The Open University

Business and Human Rights in Transition from Conflict to Peace
A panel discussion among an academic, a company representative and practitioners, held on 21 June 2016, hosted by the Oxford Business and Human Rights Research Network and the Business and Human Rights Resource Centre. How can business support or hinder the process of peace-building after armed conflict? This panel discussion looks at the role of the private sector in countries emerging from conflict. An academic, a company representative and practitioners engage with questions of corporate comp

6.2 Non-covalent bonding in site-specific binding

The affinity of a protein for DNA is determined in thermodynamic terms by the free energies of the individual components compared to the free energy of the DNA-protein complex. DNA binding proteins, which contain different binding motifs, demonstrate a wide range of thermodynamic strategies.

The affinity of a site-specific DNA binding protein for its specific DNA sequence is generally of the order of 104−107 times greater than its affinity for non-specific sequen

2011 Utzon Lecture Series: Peter Singer - Building Values
Prof Peter Singer (Princeton University) discusses the way in which our decisions about the kind of built environment we choose to create, and to live in, should take into account the interests of others, whether present or future, human or nonhuman. Australian-born philosopher Peter Singer is frequently acknowledged as a major force in modern bioethics. Peter has taught at the University of Oxford, La Trobe University and Monash University, as well as holding several visiting appointments. He

Introduction

This unit will allow you to extend your visual modelling skills through the use of the sign graph diagramming technique. You will explore the dynamic relationship between social, economic and ecological factors whose interdependencies will determine the complex dynamics of the future as it unfolds. Your final task will be to identify points of intervention within this complex system in order to "nudge" the situation towards a more favourable outcome.

How often have you seen someone endlessly seek guidance and expertise, and never actually act?

2.6 Summary

  1. Receptors comprise a limited number of structural motifs, which determine binding affinity and specificity of receptor–ligand complexes. Some ligands bind to several receptors and some receptors bind to several ligands.

  2. Acetylcholine is a good example of a ligand with two structurally different kinds of receptor. Nicotinic receptors are ion channels, which are found predominantly in skeletal muscle, and are stimulated by nicotine. Nicotinic
