Recent Advances in the Technology of Aluminium- Magnesium Alloys
ALLOYS of aluminium with copper. to which smallamounts
of manganese. magnesium and silicon are added, belong
to the well known group of alloys termed "'Duralumin ', and were amongst the earliest of aluminium alloys to
be used commercially on account of their age-hardening characteristics.
Alloys of aluminium with magnesium as the principal
alloying element, first attracted the interest of
investigators as early as 1900, and since then, cast
alloys containing as much as 10% magnesium have
been used for specified purpose
Barriers to Ethnic Minority and Women’s Enterprise:Existing Evidence, Policy Tensions and Unsettled Questions
This article presents an overarching review of the evidence regarding enterprise diversity. It discusses the context of ethnic minorities and women in enterprise and summarises research evidence relating to their relative access to finance, market selection and management skills. Policy within the field of diversity and enterprise is characterised by a number of tensions and unresolved questions including the presence of perceived or actual discrimination, the quantity and quality of ethnic minority and women-led businesses, potential market failure in the support provided to diverse enterprises and the substantive uniqueness of ethnic minority and women-led enterprises. Particular implications for policy and practice as well as directions for future research are discussed
Clinical Research Environment in India: Challenges and Proposed Solutions.
India has compelling need and keen aspirations for indigenous clinical research. Notwithstanding this need and previously reported growth the expected expansion of Indian clinical research has not materialized. We reviewed the scientific literature, lay press reports, and ClinicalTrials.gov data for information and commentary on projections, progress, and impediments associated with clinical trials in India. We also propose targeted solutions to identified challenges. The Indian clinical trial sector grew by (+) 20.3% CAGR (compound annual growth rate) between 2005 and 2010 and contracted by (-) 14.6% CAGR between 2010 and 2013. Phase-1 trials grew by (+) 43.5% CAGR from 2005-2013, phase-2 trials grew by (+) 19.8% CAGR from 2005-2009 and contracted by (-) 12.6% CAGR from 2009-2013, and phase-3 trials grew by (+) 13.0% CAGR from 2005-2010 and contracted by (-) 28.8% CAGR from 2010-2013. This was associated with a slowing of the regulatory approval process, increased media coverage and activist engagement, and accelerated development of regulatory guidelines and recuperative initiatives. We propose the following as potential targets for restorative interventions: Regulatory overhaul (leadership and enforcement of regulations, resolution of ambiguity in regulations, staffing, training, guidelines, and ethical principles [e.g., compensation]).Education and training of research professionals, clinicians, and regulators.Public awareness and empowerment. After a peak in 2009-2010, the clinical research sector in India appears to be experiencing a contraction. There are indications of challenges in regulatory enforcement of guidelines; training of clinical research professionals; and awareness, participation, partnership, and the general image amongst the non-professional media and public. Preventative and corrective principles and interventions are outlined with the goal of realizing the clinical research potential in India

Academics in pursuit of the part-time doctorate: Pressures and support issues associated with the career development of business and management academics
This article poses the question, how might the application of human resource development, career development (CD) and critical management studies perspectives cast light on the development of doctoral student? Nine part-time students took part in a longitudinal study that required them to complete monthly reflective reports or journals and participate in semi-structured interviews. Most of these part-time students are also in full-time employment as academics within ‘Post-1992' university employment in the United Kingdom. Post-1992 UK universities, also classified as ʼnew’ or ‘modern’ universities, comprised UK higher education institutions that were transformed from polytechnic institutions in or after 1992. Those part-time students within this study who are also in full-time employment as academics complained the lack of time for study has proved to be a significant hindrance and even a threat to their doctoral progress. From a critical management stance, it is proposed that power asymmetries exist between these students and the leaders of their employment organisations. These students are considered to be working towards CD within the turbulence of ʼnew’ universities, primarily in the strife for employment security. It is suggested that these concerns link with Grey’s (Grey, C. 1994) critical management perspective relating to ‘self-management’ as an example of labour process discipline. As such, this article offers a new perspective within CMS discourse, that of critical career development
Antibiotics as part of the management of severe acute malnutrition
BACKGROUND: Severe acute malnutrition contributes to 1 million deaths among children annually. Adding routine antibiotic agents to nutritional therapy may increase recovery rates and decrease mortality among children with severe acute malnutrition treated in the community. METHODS: In this randomized, double-blind, placebo-controlled trial, we randomly assigned Malawian children, 6 to 59 months of age, with severe acute malnutrition to receive amoxicillin, cefdinir, or placebo for 7 days in addition to ready-to-use therapeutic food for the outpatient treatment of uncomplicated severe acute malnutrition. The primary outcomes were the rate of nutritional recovery and the mortality rate. RESULTS: A total of 2767 children with severe acute malnutrition were enrolled. In the amoxicillin, cefdinir, and placebo groups, 88.7%, 90.9%, and 85.1% of the children recovered, respectively (relative risk of treatment failure with placebo vs. amoxicillin, 1.32; 95% confidence interval [CI], 1.04 to 1.68; relative risk with placebo vs. cefdinir, 1.64; 95% CI, 1.27 to 2.11). The mortality rates for the three groups were 4.8%, 4.1%, and 7.4%, respectively (relative risk of death with placebo vs. amoxicillin, 1.55; 95% CI, 1.07 to 2.24; relative risk with placebo vs. cefdinir, 1.80; 95% CI, 1.22 to 2.64). Among children who recovered, the rate of weight gain was increased among those who received antibiotics. No interaction between type of severe acute malnutrition and intervention group was observed for either the rate of nutritional recovery or the mortality rate. CONCLUSIONS: The addition of antibiotics to therapeutic regimens for uncomplicated severe acute malnutrition was associated with a significant improvement in recovery and mortality rates.

Re-Focusing - Building a Future for Entrepreneurial Education & Learning
The field of entrepreneurship has struggled with fundamental
questions concerning the subject’s nature and purpose. To whom and to
what means are educational and training agendas ultimately directed?
Such questions have become of central importance to policy makers,
practitioners and academics alike. There are suggestions that university
business schools should engage more critically with the lived experiences
of practising entrepreneurs through alternative pedagogical approaches
and methods, seeking to account for and highlighting the social, political
and moral aspects of entrepreneurial practice. In the UK, where funding in
higher education has become increasingly dependent on student fees,
there are renewed pressures to educate students for entrepreneurial
practice as opposed to educating them about the nature and effects of
entrepreneurship. Government and EU policies are calling on business
schools to develop and enhance entrepreneurial growth and skill sets, to
make their education and training programmes more proactive in
providing innovative educational practices which help and facilitate life
experiences and experiential learning. This paper makes the case for
critical frameworks to be applied so that complex social processes
become a source of learning for educators and entrepreneurs and so that
innovative pedagogical approaches can be developed in terms both of
context (curriculum design) and process (delivery methods)
