Entropy generation for microscale forced convection: effects of different thermal boundary conditions, velocity slip, temperature jump, viscous dissipation, and duct geometry

This work presents closed form solutions for fully developed temperature distribution and entropy generation due to forced convection in microelectromechanical systems (MEMS) in the Slip-flow regime, for which the Knudsen number lies within the range 0.001

Folate: Methods of analysis

Folates and its derivatives occur as polyglutamates in nature. The multiplicity of forms and the generally low levels in foods makes quantitative analysis of folate a difficult task. The assay of folates from foods generally involves three steps: liberation of folates from the cellular matrix; deconjugation from the polyglutamate to the mono and di-glutamate forms; and the detection of the biological activity or chemical concentration of the resulting folates. The detection methods used are the microbiological assay relying on the turbidimetric bacterial growth of Lactobacillus rhamnosus which is by far the most commonly used method; the HPLC and LC/MS techniques and bio-specific procedures. This review attempts to describe the methods along with the merits and demerits of using each of these methods.

Teamwork in Health and Rehabilitation Sciences: Evaluation of a multiprofessional workshop

This paper outlines a multiprofessional education workshop piloted and subsequently conducted with a cohort of 81 graduate entry students of occupational therapy, physiotherapy, speech pathology and audiology. The rationale for, and format of, the workshop is outlined, followed by comparisons between students' knowledge about teamwork prior to and after the four-hour workshop. The workshop was based on a real case scenario of a child with Developmental Coordination Disorder (DCD). Students completed pre- and post-workshop questionnaires about their knowledge of DCD, teamwork and the roles of various professionals and parents; and a post-workshop questionnaire about their views regarding the utility of the workshop, its strengths, and learning outcomes. The evaluation indicated that the workshop was overwhelmingly successful from the students' perspective in: (1) enhancing their understanding about DCD and its multifaceted impact on school age children; (2) developing a deeper appreciation of the importance of teamwork itself; (3) refining their understanding of their own profession's role and (4) developing an appreciation of the role of other professions and parents in working with children with complex needs, and their families. Limitations of this study and directions for future research are discussed.

Dietary carbohydrate source affects glucose concentrations, insulin secretion, and food intake in overweight cats

This study was undertaken to assess the impact of dietary carbohydrate source on food intake, body composition, glucose tolerance, insulin sensitivity, and glucose and insulin concentrations in overweight and obese cats with reduced insulin sensitivity. Sixteen overweight and obese cats were divided into two groups and randomly allocated one of two extruded diets formulated to contain similar starch content (33%) from different cereal sources (sorghum and corn versus rice). Meal response, glucose tolerance and insulin sensitivity tests were performed before and after a 6-week weight-maintenance phase and after an additional 8-week free-access feeding phase. Dual energy x-ray absorptiometry (DEXA)-derived body composition was determined in each cat before the study and after each test phase. Food intake was measured daily and body weight measured twice weekly for the duration of the study. When compared with the sorghum/corn-based diet, cats fed the rice-based diet consumed more energy and gained more weight in response to free-access feeding. Cats fed the rice-based diet also tended to have higher glucose concentrations and insulin secretion in response to a glucose load or a test meal. We conclude that a sorghum and corn blend is a superior carbohydrate source than rice for overweight cats with glucose intolerance and reduced insulin sensitivity. Such a diet may help to minimize overeating and additional weight gain, and may also reduce the risk of developing type 2 diabetes mellitus. (C) 2004 Elsevier Inc. All rights reserved.
