Oxford Brookes University is a new university in Oxford, England. It can trace its origins to 1865 when the former Oxford School of Art was established. The university was renamed in 1992 to honour its former principal, John Brookes. The university's School of Architecture is one of the largest in Britain.In 2014 it was ranked 379th in the world according to the QS World University Rankings but is not included in Times Higher Education's list of the top 400 universities in the world. Oxford Brookes is the sixth largest employer in Oxfordshire, providing over 2,800 jobs across the university. Wikipedia.

In this paper, we solve the problem of approximating a belief measure with a necessity measure or 'consonant belief function' in a geometric framework. Consonant belief functions form a simplicial complex in both the space of all belief functions and the space of all mass vectors: Partial approximations are first sought in each component of the complex, while global solutions are selected among them. As a first step in this line of study, we seek here approximations that minimize Lp norms. Approximations in the mass space can be interpreted in terms of mass redistribution, while approximations in the belief space generalize the maximal outer consonant approximation. We compare them with each other and with other classical approximations and illustrate them with the help of a running example. © 1993-2012 IEEE.

Plant myosins are required for organelle movement, and a role in actin organization has recently come to light. Myosin mutants display several gross morphological phenotypes, the most severe being dwarfism and reduced fecundity, and there is a correlation between reduced organelle movement and morphological defects. This review aims to discuss recent findings in plants relating to the role of myosins in actin dynamics, development, and organelle movement, more specifically the endoplasmic reticulum (ER). One overarching theme is that there still appear to be more questions than answers relating to plant myosin function and regulation. © 2011 The Author.

Eukaryotic flagella are microtubule-based structures required for a variety of functions including cell motility and sensory perception. Most eukaryotic flagella grow out from a cell into the surrounding medium, but when the flagellum of the protozoan parasite Trypanosoma brucei exits the cell via the flagellar pocket, it is attached along the length of the cell body by a cytoskeletal structure called the flagellum attachment zone (FAZ). The exact reasons for flagellum attachment have remained elusive, but evidence is emerging that the attached flagellum plays a major role in cell morphogenesis in this organism. In this review we discuss evidence published in the past four years that is unravelling the role of the flagellum in organelle segregation, inheritance of cell shape and cytokinesis. © 2010 Elsevier Ltd.

Renewable and Sustainable Energy Reviews | Year: 2012

The price of hydroelectricity in Cameroon has recently sky-rocketed. At the same time, firewood in remote areas is being depleted without being replenished. This has led to a number of challenges; energy is no longer affordable and environmental impacts from the wanton exploitation of firewood are widespread. Therefore, there is a need to explore other renewable energy sources which have enormous environmental and energy potentials. However, there is limited scholarly work on the potential of other renewable energy sources in Cameroon. Literature on the potential of renewable energy in Cameroon is still very limited and scattered. The exact sizes of the different renewable energy sources, their benefits and the market potential that can stimulate their uptake are not well-known. Therefore, stakeholders including policy makers, researchers and investors lack guidelines on how and at what level to invest, intervene, and design policies that can lead to the practical exploitation of renewable energy sources. This article investigates the extent to which renewable energy can contribute to the energy sector in Cameroon. The article lays the groundwork that can inform various stakeholders to engage into different activities which can foster the understanding of renewable energy sources and their potentials and limitations. Some key findings are that: while solar and biomass energy are abundant almost everywhere in Cameroon, wind energy is feasible in some selected regions. Furthermore, while the few literature sources about geothermal sources are contradictory or at best non-conclusive about their potential, tidal energy is yet to receive considerable attention, with its first feasibility studies having been just recently begun. These findings point to the fact that if renewable energy is to be part of the Cameroon's energy programme, there is need to scale-up research in the development of renewable energy in order to better inform energy policies. © 2012 Elsevier Ltd.

Organelle movement in plants cells is extremely dynamic. Movement is driven by the acto-myosin system. Higher plant myosins fall into two classes: classes XI and VIII. Localization studies have highlighted that myosins are present throughout the cytosol, label motile puncta and decorate the nuclear envelope and plasma membrane. Functional studies through expression of dominant-negativemyosin variants, RNAi (RNA interference) and T-DNA insertional analysis have shown that class XI myosins are required for organelle movement. Intriguingly, organelle movement is also linked to Arabidopsis growth and development. The present review tackles current findings relating to plant organelle movement and the role of myosins. ©The Authors.
