Description: A numerical model has been developed to predict the three-dimensional flow character within low scope vertical slot fishways (VSFs). The modek solves the three dimensional Reynolds averaged Navier-Stokes equations, closed with the renormalised k-e turbulence formulations. The model employs the volume of fluid method to deal with the free surface. Results are presented for velocities and surface elevations utilising two fishway designs from prototype and laboratory studies. The respective data from the studies are direct compared to the numerical model predictions forming the basis of verification. The model is shown to predict critical design velocities, slot flow characteristics, flow recirculation and water surface elevations well enough to be useful in low slope VSF design.

Description: NKT cell subsets can be divided based on CD4 and NK1.1 expression and tissue of origin, but the developmental and functional relationships between the different subsets still are poorly understood. A comprehensive study of 19 cytokines across different NKT cell subsets revealed that no two NKT subpopulations exhibited the same cytokine profile, and, remarkably, the amounts of each cytokine produced varied by up to 100-fold or more among subsets. This study also revealed the existence of a population of CD4-NK1.1 - NKT cells that produce high levels of the proinflammatory cytokine IL-17 within 2-3 h of activation. On intrathymic transfer these cells develop into mature CD4-NK1.1+ but not into CD4 +NK1.1+ NKT cells, indicating that CD4-NK1. 1- NKT cells include an IL-17-producing subpopulation, and also mark the elusive branch point for CD4+ and CD4- NKT cell sublineages.

Description: Global statistics of HIV/AIDS infection reveals the disastrous effects of discrimination against women in the area of human health. Women’s vulnerability to HIV/AIDS reflects their wider social, economic and sexual disadvantages compared to their male counterpart. Although the gender context of HIV/AIDS has received a considerable attention recently, however, in case of Vietnam gender aspects of the epidemic have still been a neglected area of research. Little is known about how gender affects the epidemic as well as how the epidemic affects the life of women. This paper reveals that the gender context of HIV/AIDS epidemic in Vietnam has a much complex reality. Institutions, social norms and opportunity structures, of which “Doi Moi” [Renovation] has become an integral part, combine to create new norms and conditions put women more vulnerable to HIV/AIDS. A gendered strategy is crucial in order to successfully fight against the growing HIV/AIDS epidemic

Description: Iron-sulfide minerals in benthic sediments may sequester potentially toxic trace elements that are introduced to estuaries from natural and anthropogenic sources (Chapman et al., 1998, Morse and Luther, 1999, Simpson et al., 2002 and Teasdale et al., 2003). Understanding iron-sulfide formation in benthic sediments is therefore central to assessing the risk posed by sedimentary trace elements (Machado et al., 2004, Burton et al., 2005a and Burton et al., 2006a). This report provides a baseline description of sedimentary iron-sulfide and trace element behaviour in Coombabah Lake – a sub-tropical estuarine lake in southern Moreton Bay, Australia (Fig. 1).

Description: This article reports research conducted on students’ perceptions of assessment in science classes in Queensland and Western Australia. A specially developed instrument, the Student Perceptions of Assessment Questionnaire (SPAQ) which assesses Congruence with Planned Learning, Authenticity, Student Consultation, Transparency, and Diversity was used to collect data from 3,055 students. Hierarchical cluster analysis resulted in a four cluster solution being accepted. While one cluster of 799 students held positive perceptions of assessment, another cluster of 640 students held negative views. The SPAQ allows for a greater focus on classroom-based perceptions of assessment rather than crude external accountability measures that decontextualise classroom assessment.
