Questionnaire surveys to passengers in metro have been performed. Frequency distribution statistics was conducted about their personal information, environmental information and human behavior information in fire. On the basis on that, the author made a comparison between results of this research and ones of other researches for buildings fires in domestic, and gained a coincident result. These conclusions will provide more accurate and more effective supports for fireproofing design. At the same time, these conclusions also are good for the fire prevention and environment protection.Questionnaire surveys to passengers in metro have been performed.

Eggs And Larvae

Worms infection is still common in Indonesia with a prevalence that varies around 40% -60% at all ages. This disease can be caused by infection of Soil-Transmitted Helminths (STH) that require soil media to infect humans. The many plantation lands in Jember are a suitable environment for the development of STH and STH identification in soil can be done by flotation method using MgSO4 solution or sucrose. The comparison of the effectiveness of the MgSO4 solution with the sucrose solution has not been widely studied. Therefore, the aim of this study was to compare the efficacy of using saturated MgSO4 solution with saturated sucrose to identify eggs and larvae of STH in Sumber Wadung plantation soil, Hargomulyo Village, Silo District, Jember Regency using the flotation method. Soil samples were taken as many as 35 samples in the garden area, 35 samples around the river, and 35 samples in residential areas,. The results of identification of STH eggs and larvae obtained Ascarid eggs (1.9%) and Hookworm larvae (0.01%). The number of positive soil samples containing STH eggs and larvae using different solutions is the same as three samples (0.02%).The Wilcoxon test results showed that there was no difference in the results of using the MgSO4 solution with the sucrose solution in the flotation method (p> 0.05) so that the MgSO4 solution and sucrose solution could be used to detect eggs and larvae of STH worms and had the same effectiveness.

All food needs to be free of contaminants, especially pathogens that may be harmful to health. The food security is achieved when strict quality control conditions are used during the preparation. The objective of this work was to analyze the hygienic-sanitary conditions during the school meals preparation. The research included microbiological analysis from food, hands of those handling the food, and the utensils used in the preparation. The samples analyzed, collected from eight schools, were of vegetables, the surface of hands, plastic bowls and chopping boards. Microbiological analyses were performed at the food microbiology laboratory of Integrado University of Campo Mourão, where the following microorganisms were researched: Coliforms at 35°C and at 45°C; mesophyll; Salmonella spp. and coagulase-positive strains of Staphylococcus according to the procedures determined by APHA and number 62 Normative. In the analysis of vegetables there were not positive results for Salmonella nor coagulase-positive strains of Staphylococcus; but 12.5 % showed contamination by coliforms at 35°C, and 12.5% by coliforms at 45°C. All the samples of the hands showed contamination by mesophyll, 6.25% were contaminated by Coliforms at 35°C and 6.25 % by coliforms at 45°C. None of the samples of utensils was positive for Salmonella, however, 12.5% of them were contaminated by coliforms at 35°C and 12.5 % by coliforms at 45 °C. It is concluded that it is necessary the adoption of corrective and preventive steps in order to produce safe food in the analyzed schools.

AbstractWe develop a figure of merit for SETI observations which is anexplicitfunction of the EIRP of the transmitters, which allows us to treat sky surveys and targeted searches on the same footing. For each EIRP, we calculate the product of terms measuring the number of stars within detection range, the range of frequencies searched, and the number of independent observations for each star. For a given set of SETI observations, the result is a graph of merit versus transmitter EIRP. We apply this technique to several completed and ongoing SETI programs. The results provide a quantitative confirmation of the expected qualitative difference between sky surveys and targeted searches: the Project Phoenix targeted search is good for finding transmitters in the 109to 1014W range, while the sky surveys do their best at higher powers. Current generation optical SETI is not yet competitive with microwave SETI.

Gas Reactions

Studying the behavior of surfaces at high temperatures is of great importance for understanding the properties of ceramics and associated surface-gas reactions. Atomic processes occurring on bulk crystal surfaces at high temperatures can be recorded by reflection electron microscopy (REM) in a conventional transmission electron microscope (TEM) with relatively high resolution, because REM is especially sensitive to atomic-height steps.Improved REM image resolution with a FEG: Cleaved surfaces of a-alumina (012) exhibit atomic flatness with steps of height about 5 Å, determined by reference to a screw (or near screw) dislocation with a presumed Burgers vector of b = (1/3)<012> (see Fig. 1). Steps of heights less than about 0.8 Å can be clearly resolved only with a field emission gun (FEG) (Fig. 2). The small steps are formed by the surface oscillating between the closely packed O and Al stacking layers. The bands of dark contrast (Fig. 2b) are the result of beam radiation damage to surface areas initially terminated with O ions.
