Quasielastic K+ scattering in nuclei

The quasielastic scattering kaon-nucleus experiment performed at BNL is analyzed in a finite nucleus continuum random phase approximation framework, treating the reaction mechanism in Glauber theory up to two-step inelastic processes. A good description of the data is achieved, also providing a useful constraint on the strength of the effective particle-hole interaction in the scalar-isoscalar channel at intermediate momentum transfers.Comment: 4 pages, 3 figures, needs espcrc1 and epsfig; presented at the International Conference on Hypernuclear and Strange Particle Physics, BNL October 13-18, 199

Digital world, lifeworld, and the phenomenology of corporeality

The contemporary world is characterised by the pervasive presence of digital technologies that play a part in almost every aspect of our life. An urgent and much-debated issue consists in evaluating the repercussions of these technologies on our human condition. In this paper, I tackle this issue from the standpoint of Husserlian phenomenology. I argue that phenomenology offers a contribution to our understanding of the implications of digital technologies, in the light of its analysis of the essential structures of human experience, and especially of its corporeal grounding. In the light of this analysis, it is possible to investigate the ways in which these essential structures are affected by digital technologies. In particular, it is possible to highlight the ways in which some digital technologies involve a process of disembodiment or simply a superficial embodiment of experience

The anatomy of the muscle wall of the human colon : the inter-taenial continuity of the longitudinal muscle coat

This report is, in modified form, part of the thesis presented by Dr. Pace for his Ph.D. The work reported was done whilst he was a Commonwealth Scholar in the Department of Anatomy at the Middlesex Medical School, London. Contradictions exist in the literature as to whether the outer muscle coat of the human colon is complete or not. There are conflicting points of view as to the presence and extent of the longitudinal muscle in between the taeniae. The material used consisted of 112 human colons, mainly postmortem, from subjects ranging in age from early fetal to 88 years. Portions from the named regions of the colon fixed in various states of distension were examined. The methods of microdissection were combined with those of histology. Sections, transverse of the whole circumference and longitudinal of the intertaenial wall, were studied. It was found that in the human colon the outer longitudinal coat, though thin in between the toenia, forms a complete and continuous layer. This is so at all ages, in all regions of the colon and in all states of distension except maximal when the muscle fascicles become separated by gaps filled in with connective tissue. Under no circumstances was the outer coat found to consist only of a few scattered longitudinal fibres and isolated bits of muscle, or to be entirely absent.peer-reviewe

A feasibility study to investigate the effectiveness and safety of an intermittent fasting diet for weight reduction in adults with Type 2 Diabetes treated with insulin : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Human Nutrition at Massey University, Albany, New Zealand

Background: Type 2 diabetes (T2DM) is the most common form of diabetes. Obesity is associated with both the development of T2DM and also the development of the complications of diabetes; increasing health care costs and morbidity and mortality. Weight loss and control of blood glucose levels should be managed with a tailored eating plan developed in negotiation between the person with diabetes and their health care team. It is essential that health care professionals are familiar with different strategies that achieve weight reduction, glycaemic and cardiovascular risk reduction goals. One emerging weight reduction strategy is fasting diets. There is currently a gap in the knowledge of whether fasting diets are an effective and safe weight reduction strategy for people with T2DM on insulin. Aim: To investigate the effectiveness and safety of an intermittent fasting diet (two day per week) as an alternative to standard dietary advice (portion control diet) for weight reduction in obese adults with insulin dependent T2DM attending a 12-week group based intervention at Waitemata District Health Board (DHB). Methods: Obese patients with T2DM treated with insulin who were attending Waitemata DHB Diabetes Service were recruited for this two arm open-label design intervention feasibility study. Both dietary strategies were implemented during a 12-week intervention at which participants received monthly dietitian-led group education and support. The intermittent fasting diet (IFD) intervention (n=8) investigated was a two day per week reduced energy intake (550-650kcal / 2300- 2700kJ per day) and five days’ usual intake making low fat choices. The portion control diet (PCD) was the comparison group (n=7) and focused on daily energy restriction through reduction in portion sizes and low fat food choices in line with current New Zealand dietary recommendations for management of T2DM. Results: Similar weight loss was achieved in both groups (IFD: 2.7 ± 3.0 kg, PCD: 1.7 ± 2.5 kg). This reduction was not significant between groups. There was a significant difference between groups in reduction in HbA1c. (P=0.003) (IFD: -11 mmol/mol, PCD: -3 mmol/mol). This decrease was significant in the IFD group only (P=0.018). Reported hypoglycaemic events were low in both groups (8 events in IFD; 21 events in PCD). Non-significant between group reductions in waist circumference (P=0.402), waist: height ratio (P=0.455), diastolic (P=0.189) and systolic blood pressure (P=0.443) were observed. Lipid profile remained stable in both groups. Conclusion: This feasibility study showed that an intermittent fasting diet can achieve similar weight loss to current standard practice dietary advice in people with T2DM. However, it is the significant reductions in HbA1c compared to a daily energy restriction diet over a three-month period seen in this study that warrant further investigation. With education from health care professionals and modification of insulin on pre-fasting and fasting day this diet may be followed safely and hypoglycaemia avoided or managed appropriately
