An Upper Bound on the Critical Value Involved in the Blasius Problem
Yang GC
Journal of Inequalities and Applications , 2010,
Abstract: Utilizing the Schauder fixed point theorem to study existence on positive solutions of an integral equation, we obtain an upper bound of the critical value involved in the Blasius problem, in particular, . Previous results only presented a lower bound and numerical investigations .

Abstract: Two new classes of growth morphologies, called doublons and seaweed, were simulated using a phase-field method. The evolution of doublon and seaweed morphologies was obtained in directional solidification. The influence of orientation and velocity on the growth morphology was investigated.It was indicated that doublons preferred growing with its crystallographic axis aligned with the heat flow direction. Seaweed, on the other hand, could be obtained by tilting the crystalline axis to 45°. Stable doublons could only exist in a range of velocity regime. Beyond this regime the patterns formed would be unstable. The simulation results agreed with the reported experimental results qualitatively.
Microbiological quality of poultry meat: a review
Mead, GC;
Revista Brasileira de Ciência Avícola , 2004, DOI: 10.1590/S1516-635X2004000300001
Abstract: poultry meat can be contaminated with a variety of microorganisms, including those capable of spoiling the product during chill storage, and certain foodborne pathogens. human illness may follow from handling of raw meat, undercooking or mishandling of the cooked product. while salmonella and campylobacter spp. remain the organisms of greatest global concern in this respect, others present include the more recently reported arcobacter and helicobacter spp. and, occasionally, verotoxigenic escherichia coli. also considered here is the growing problem of antimicrobial resistance among poultry-associated pathogens. because of the need for a systematic and universally applicable approach to food safety control, the hazard analysis critical control point (haccp) concept is increasingly being introduced into the poultry industry, and quantitative risk assessment (qra) is being applied to microbial hazards. among a number of completed and on-going studies on qra are those undertaken by fao/who on salmonella and campylobacter in broilers. in the case of campylobacter, however, any qra must assume at present that all strains have the same pathogenic potential for humans and comparable survival capabilities, even though this is unlikely to be the case. implementation of the haccp system in poultry processing plants addresses zoonotic agents that are not detectable by conventional meat inspection procedures and can help to control contamination of carcasses with spoilage organisms. the system brings obvious benefits in optimising plant hygiene, ensuring compliance with legislation and providing evidence of 'due diligence' on the part of the processor. it is now being applied globally in two different situations: in one, such as that occurring in the usa, carcass contamination is clearly reduced as carcasses pass through the process and are finally chilled in super-chlorinated water. there is also the option to use a chemical-rinse treatment for further reduction of microbial c
Effective Information Provision as a Panacea for The Resolution Of Conflict In Autonomous Communities: A Case Study Of Amiyi Akah Community
GC Umunnakwe
Information Manager (The) , 2009,
Abstract: The paper studied the Amiyi Akah Community, a village in Umuaka Autonomous Community in Njaba Local Government area of Imo State, Nigeria. The paper adopted a survey method and used questionnaire complemented with unstructured interviews and observation to elicit the desired responses. In all, the target population was 10% of the entire population. Since it runs in thousands only 1480 were used. Data collected were analyzed using tables and graphic representations. In conclusion, it was observed that autonomous community creation is a welcome venture if the government would strictly stipulate guideline be used in Ezeship election of which has been the major source of conflict. Communities should work towards establishing rural libraries and information centres to help in keeping the populace educated and informed on the on-goings in the society.
The Clausewitzian and Heuristic Evolution of the ANC' s Armed Struggle: A Dependent Pillar of the South African Revolution
GC Khwela
Scientia Militaria: South African Journal of Military Studies , 2000,
Abstract: The paper tries to address the armed struggle as one of the pillars of the South African revolution, especially its adoption, together with the underground component, after all other avenues had been restricted. The argument emphasises the centrality of the political struggle, particularly the other two pillars of the revolution: mass mobilisation and international isolation of the racist government. The armed struggle and the underground are regarded as extension pillars necessitated by objective conditions, which demanded the ANC to reveal its existence through other means, since it was banned as a legal political force internally. This argument is stressed by looking at the nature of the adoption of the armed struggle, its heuristic evolution, from armed propaganda until the late 1970s, and particularly the 1980s, when there was more focus on revolutionary people's war, its protracted nature, the role and structure of the people's army, and the armed seizure of political power through insurrection. Thereafter the paper discusses the debate that emerged with the realisation that there were possibilities of a negotiated settlement, the subsequent contest between absolute and relative victories, and the preparation of the cadres for integration into the new SANDF. The paper concludes with the need to revisit the Integration Process, especially the need to re-orient the uniformed members' political attitudes towards a common cause. "No people can accept slavery for ever. We have reached a stage where we have taken a decision to liberate ourselves, and no force on earth can stop us from attaining that objective."
A ten-year histopathological study of generalised lymphadenopathy in India
GC Kamat
South African Family Practice , 2011,
Abstract: Background: Lymphadenopathy is a rather common clinical finding in a primary healthcare setting, and may be due to inflammatory lesions and tumours. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. This study was undertaken to study the histopathology of generalised lymphadenopathy in India, as well as the demographics of the study population. Method: This study was conducted for a period of 10 years (August 1997-July 2007), of which eight years were retrospective, from August 1997-July 2005, and two years were prospective, from August 2005-July 2007. The source of data for this study was patients seeking medical attention, who, on clinical examination, were found to have generalised lymphadenopathy. A representative node was excised for histopathology. Tissues were routinely processed, stained with haematoxylin and eosin, and examined by means of light microscopy. Results: Of the 244 lymph node biopsies analysed in this study, 75 cases (30.73%) were reactive lymphadenitis, 142 cases (58.19%) showed granulomatous lymphadenitis, one case (0.40%) was Hodgkin’s lymphoma, eight cases (3.27%) were non-Hodgkin’s lymphoma, and 18 cases (7.37%) were metastatic malignancy. Conclusion: In this study, the most common cause of generalised lymphadenopathy was granulomatous lymphadenitis, followed by reactive lymphadenitis. Among the neoplastic lesions, metastatic malignancy accounted for most cases.
