AIMS To use BioBall cultures as a precise reference standard to evaluate methods for enumeration of Escherichia coli and other coliform bacteria in water samples. METHODS AND RESULTS Eight methods were evaluated including membrane filtration, standard plate count (pour and spread plate methods), defined substrate technology methods (Colilert and Colisure), the most probable number method and ...

Use of composites for a range of structural application in aircrafts, space-crafts, automobiles, etc., has widely spread in the last few years. Other than weight reduction, cut-outs provide pathways to link different aircraft parts. In this paper, an experimental investigation was conducted to study the effect of a cut-out on the tensile strength of the fiber glass/ epoxy composite plate. Geome...

abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

In 1839, the daguerreotype photographic process was first presented to the scientific community in France. The technology spread rapidly and was widely used around the globe until roughly 1860. Image formation can be generalized into four steps: 1) exposing silver-plated copper to an iodine plus or minus another halogen vapor(s), 2) further exposing the sensitized plate to visible light within ...

Left-right asymmetry is initiated during chick embryogenesis in small domains near Hensen's node. Subsequently, broad asymmetric gene expression domains are established in the lateral plate mesoderm, ultimately determining the directionality of morphogenetic events. The transfer of asymmetric information from the node to the lateral plate is mediated by Caronte (Car), a novel member of the Cerb...

In my research work, I primarily focused on the investigation of yogurt (made from home-made raw milk) spoilage by microbiological and dielectric measurements. During experiment, continuously monitored changes in aerobic anaerobic Lactobacillus cell counts product, as a possible process would cause deteriorative microbes to displace lactic acid bacteria, also properties sample material at 400 M...
