Orchestrating cell separation in plants : what are the risks and benefits?
In this podcast, Professor Roberts from the School of Biosciences discusses his research into the mechanism responsible for regulating cell separation in plants. In particular how plants ‘shed’ parts of themselves such as leaves or fruit. Professor Roberts explores the potential application of his research, through prevention or encouraging of the ‘shedding’ process, agricultural harvests could potentially be increased or even synchronised. Professor Roberts also discusses the resistance

Ahead of the digital environments expansion which follows the principles of the web 2.0, one can notice a growing opening for user's participation. The proposal of this research is to reflect on how this scenario of participation is strengthening a social structure capable of actively acting not only in the production of digital content, but also in the form of this content presentation. From a survey of cases and a theoretical review, this paper aims to analyze two different types of user?s inf

Our taster sessions give students the chance to develop and build on the knowledge and understanding of a particular writing form. It's also an opportunity for you to develop the independent practice skills crucial to a professional writer and an opportunity to develop writing industry contacts. All MA Professional Writing students spend time exploring different forms of writing before deciding which area they wish to specialise. Specialisms might be in the field of Business Writing, Features W
Organic chemistry is important in many areas of industry and in the field of pharmaceuticals. In this module you will explore some of the key aspects of organic chemistry in the context of the design and delivery of drugs. This brings together issues of fundamental research, industrial scaling up of processes, environmental impact and patent law.
This session will introduce you to electric and magnetic fields. We’ll look at what we mean by a field and at what electric charge is and relate the two through Gauss’s theorem. From this we’ll derive Coulomb’s law for the force between charges. Then we’ll look at the concept of electrical potential which is related to the work done in moving a charge through a field. We’ll return to the notion of capacitance which we used in session 4, this time looking at how capacitance is compute
In this session we’ll begin with Faraday’s law of electromagnetic induction. We’ll describe and use the analogy between a current loop and a magnetic dipole and study the magnetic energy in various situations, including the energy density of a magnetic field. Finally we’ll look at magnetic forces from the point of view of the interaction between moving electrical charges, the Lorentz force law, and describe the force between current carry wires, the Biot-Savart law.
In this session we’ll look at certain macroscopic properties of solids that result from the quantum mechanical behaviour of electrons. This field of physics initially concerned just the behaviour of solids so was referred to as solid state physics. It has been called condensed matter physics since the late 1960s, when it was realised that the type of collective behaviour extended beyond that of electrons in solids to many other systems such as, for example, superfluids.

It is necessary to form a stable dispersion of nanotubes in order to properly integrate them into polymeric systems. This can be achieved by treating them with acid to oxidise the tube surfaces. The tubes will then spontaneously disperse in an aqueous medium. The viscosity of these suspensions is analogous to that of polymers; it increases gradually with concentration up to a critical point (at about 0.7 vol%) where entanglement occurs. However, their separation is determined more by surface rep
A hypoeutectoid alloy (carbon composition less than eutectoid). The first phase formed upon cooling from the austenite phase field is proeutectoid ferrite. Due to the lower solubility of carbon in ferrite, carbon is partitioned into the remaining austenite. At the eutectoid point the remaining carbon enriched austenite transforms to pearlite (a mixture of ferrite and cementite) which is the darker region of the micrograph. The proportion of pearlite is dependent upon the overall composition. The
This is a hypoeutectoid alloy, which has been air cooled from the austenite phase field at 950 °C. The first solid to form is proeutectoid ferrite, its morphology being determined by the cooling rate. At slow cooling rates (furnace cooling) there is sufficient time for the carbon rejected from the austenite to diffuse and equilibrium solidification occurs. With faster cooling the microstructure also depends on the original austenite grain size.Fast cooling and large grain size favours ferrite f

In the field with Simon Haslett, Professor of Physical Geography and Director of the Centre for Excellence in Learning and Teaching at the University of Wales, Newport, and Professor Jon Nott of James Cook University. Whilst Simon and Jon were in the field in Queensland, Jon received a phone call to do a radio interview about an earthquake and tsunami that had occurred in New Zealand the day before and generated a small tsunami that arrived along the southeast coast of Australia.

A central issue in acquiring knowledge is its appropriate transfer beyond the contexts and contents of first acquisition. In contrast to dominant "common elements" transfer theory, an interpretive perspective is developed, according to which "appropriate transfer" is a concept socioculturally rather than objectively defined. "Elements" perceived by the thinker as common between the current and a prior situation are not given in the nature of things but "read in terms of the thinker'sculturally-i
