Pulsatile fully developed flow in rectangular channels

Solutions for pulsatile fully developed flow of Newtonian viscous fluid in a straight rectangular channel can be synthesized from analytic solutions of steady flow and oscillatory flow. A new steady solution is presented that is valid for all duct aspect ratios. Also new oscillatory solutions are given, showing dependence on a “viscous diffusion length”, the square root of the kinematic viscosity divided by frequency.     

Preschoolers Reduce Inequality While Favoring Individuals With More

Inequalities are everywhere, yet little is known about how children respond to people affected by inequalities. This article explores two responses—minimizing inequalities and favoring those who are advantaged by them. In Studies 1a (N = 37) and 1b (N = 38), 4‐ and 5‐year‐olds allocated a resource to a disadvantaged recipient, but judged advantaged recipients more positively. In Studies 4 (N = 38) and 5 (N = 74), a delay occurred between seeing the inequality and allocating resources, or stating a preference, during which time participants forgot who was initially more advantaged. Children then favored advantaged recipients on the preference and resource allocation measures, suggesting an implicit “affective tagging” mechanism drives the tendency to favor the advantaged. In contrast, reducing inequalities through resource allocation appears to require explicit reasoning.     

On Consultation and Beginner Educational Psychologists

In this article, we describe some of our purposes and processes when introducing consultation as a comprehensive model of service delivery to course members in their programme of initial professional education. We also note some of the impacts from this model, both in the course modules and the placement experiences. While it is written from the perspective of course tutors, we hope that this account may trigger useful thoughts for readers-about their own initial training, about their current model of practice, about their current professional development or even their current contribution to initial training.     

Comparative study on lipid peroxidation and antioxidant vitamins E and C inFalciparum andVivax malaria

Reactive oxygen species are thought to be involved in the pathogenesis of Malaria. To assess the extent of oxidative stress, a study was conducted in patients withPlasmodium falciparum malaria andPlasmodium Vivax malaria. Plasma Thiobarbituric acid reactive substances (TBARS) were measured to assess the degree of lipid peroxidation. Antioxidant status was measured by estimating the levels of Vitamins E and C. Results were compared with age and sex matched control subjects. This study suggests that plasma TBARS levels were significantly increased in malaria patients. The patients withP. falciparum infection showed significantly increased levels of lipid peroxides when compared toP. vivax malaria. The antioxidant Vitamins E and C were decreased significantly in malaria patients in both the groups. Maximum decline in Vitamin C was observed inP. vivax malaria. Therefore it is been hypothesized that antioxidant Vitamins E and C could provide protection against the oxidative stress induced by malaria.     

Student support via audio teleconferencing: Psycho‐educational workshops for post‐bachelor nursing students

Abstract

Although the provision of student services for distance learners is recognized as critical, the development of effective services for distance learners has been minimal. This paper will provide an overview of a recently initiated project designed to provide student services via audio teleconferencing to a population of Post‐R.N. Bachelor of Nursing students at the University of Calgary. A series of psycho‐educational workshops was developed to ease the transitions first to the distant student role and then back to the role of worker. These workshops were implemented and evaluated in terms of both process and content. Evaluation results indicated that the teleconference delivery of psycho‐educational workshops is effective in providing support services to distance students.
