background : there are several methods, such as vaccination, to control visceral leishmaniasis. although there is no efficient vaccine, it seem dna vaccination with stimulates both cellular and humoral immunity apparently is the best way. the aim of this study was cloning and expression of lack gene, a 36kd protein, as a can-didate protein for vaccination against iranian l.infantum. methods: ir...

Musical fit, the congruence between music and product leading to improved response, is presented as an explanation of differences in recall of food items from two cultures. Musical fit predicts that, in this case, more Indian food items would be recalled when Indian music was playing, and more Malay food items would be recalled when Malay music was played. The underlining premise of this predic...

Fit testing of tight-fitting respiratory protective facepieces has been in use for some years, but there are still widespread misconceptions and misunderstandings about what a fit test pass actually signifies. Various aspects frequently generate research papers, and there are three relevant ones in this issue (Han and Lee, 2005; Kuo et al., 2005; Vaughan and RajanSithamparanadarajah, 2005). In ...

he goal of the ApL solar physics research program is to deepen our understanding of the fundamental physical processes on the sun. For this purpose we have built and tested innovative solar instruments and telescopes such as the Flare genesis experiment and the solar bolometric imager. This article briefly describes the instrumentation program and then focuses on the scientific advances achieve...

Truss structures are widely used for the support of structural loads in applications where minimum mass solutions are required. Their nodes are normally constructed to resist rotation to maximize their stiffness under load. A multi-link node concept has recently been proposed that permits independent rotation of tetrahedral trusses linked by such a joint. High authority shape morphing truss str...

The axostyles of the flagellates Oxymonas, Saccinobaculus, and Notila are large ribbon-shaped structures which undulate actively in the cytoplasm. The form of their movements is described and illustrated. Axostyles consist of regular arrays of longitudinal fibres, the number of which varies between 100 and 5000 in different species. The fibres are about 240 A in diameter, apparently hollow, reg...

This study investigated the presence of microplastics in two common edible bivalves Vietnam, hard clam (Meretrix lyrata) and undulate venus (Paratapes undulatus), from estuaries Da Nang city. Microplastics were detected both species with relatively high concentrations—from 2.17 ± 0.43 to 2.38 1.28 items g−1 clams 4.71 2.15 5.36 2.69 clams. Fibers most dominant form microplastic clams, a proport...
