The heat resistance of foot-and-mouth disease virus (FMDV) strains isolated from outbreaks in Thailand was investigated in phosphate-buffered saline (PBS) at 50, 60, 70, 80, 90, and 100 degrees C. The first-order kinetic model fitted most of the observed linear inactivation curves. The ranges of decimal-reduction time (D value) of FMDV strains at 50, 60, 70, 80, 90, and 100 degrees C were 732 t...

The effects of ultrasonic power, treatment time and holding on AZ80 magnesium melt purification by field were studied. results indicate that can accelerate the separation inclusions attain purification. When alloy is treated with power 80 W at 650 °C for 60 s 100 s, best achieved. Moreover, effect degassing AZ91 was also investigated. 150 90 hydrogen content efficiency are 9.6 cm3/100 g 50.5%, ...

sera from ninety one patients clinically suspected to extra intestinal amoebiasis (ex-am) were collected and examined for presence of anti entamoeba histolytica (e.h) antibody. the tests were indirect immunofluorescence antibody, (ifa or iif), gel diffusion (gd) and counter immuno electrophoresis (ciep). thirty one patients (34%) had anti e.h. antibody titres of >1:80. among them eight patients...

OBJECTIVE We aimed to estimate the effective dose of 4D-Perfusion-CT protocols of the lung, liver, and pelvis for the assessment of tumor vascularity. MATERIALS AND METHODS An Alderson-Rando phantom equipped with thermoluminescent dosimeters was used to determine the effective dose values of 4D-Perfusion-CT. Phantom measurements were performed on a 128-slice single-source scanner in adaptive ...

A new fluorescence in situ hybridization assay based on peptide nucleic acid probes (MTB and NTM probes targeting tuberculous and nontuberculous species, respectively) for the identification of Mycobacterium tuberculosis complex and differentiation between tuberculous and nontuberculous mycobacteria (NTM) was evaluated using Lowenstein-Jensen (LJ) solid cultures from 100 consecutive sputum samp...

BACKGROUND FEV(1) is endorsed by the National Asthma Education and Prevention Program as a means for grading asthma severity. However, few data exist on the relationship between FEV(1) and asthma outcomes during long-term follow-up. OBJECTIVE We explored the relationship between the percent predicted FEV(1) (FEV(1)%) and subsequent asthma attacks in a longitudinal study of pediatric lung heal...

hydatidosis, caused by the larval stage of echinococcus granulosus, is one of the most important zoonosis with worldwide distribution. as its diagnosis by clinical symptoms and scanning alone is difficult and confusing, we designed the present study to achieve a sensitive and simple diagnostic method for epidemiological studies. sera (250 samples) were collected from 90 cases of hydatidosis pro...

Abstract In this study we determined the effect of variations in composition and particle size Red Sand (RS) grains on quality concrete. Concrete was prepared as cubes 15 cm 3 with a cement, sand gravel ratio 1:2:3 water to cement 0.5. Variations RS (fine aggregate) are 0 %, 5 10 20 % weight red grain were 80 mesh, 100 120 mesh. Mechanical properties maximum concrete pressure strength test at a...

the life table parameters of macrosiphum rosae l. (hemiptera: aphididae) on five vermicompost-tea (tea-compost) concentrations (20, 40, 60, 80 and 100%) and control treatment (0%) on rosa hybrida l. were determined under laboratory conditions. there were significant differences among pre-imaginal period and adult longevity of the aphid on the five teacompost concentrations. the highest mortalit...
