Ge distributions in ten iron meteorites with bulk Ge contents of 8.7 to 2000 ppm have been measured by electron probe microanalysis. Ge is concentrated almost entirely in the metallic phases. It was redistributed in the temperature range at which the Widmanstatten pattern developed. Ge content shows a positive correlation with Ni content, reaching a maximum in taenite and a minimum in kamacite ...

This paper reports two multitransducer vacuumsealed capacitive barometric pressure sensors, one using singlelead and the other using multiple-leads to transfer the electrical signal out of the vacuum-sealed reference cavity. The first device operates with a resolution of 37 mtorr over a pressure range from 600 to 800 torr. The sensitivity is 27 fF/torr (3000 ppm/torr). The TCO at 750 torr is 39...

A method was developed for rapid separation and determination of iron by employing capillary zone electrophoresis (CZE) technique with direct UV detection. Iron could be separated from matrix uranium by direct injection of dissolved sample solution into capillary using a mixture of 10 mM HCl and 65 mM KCl (pH = 2) as background electrolyte (BGE) at an applied voltage of 15 kV. The developed met...

lead (pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. in this study, the effect of pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. the results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µm) of pb, agropyron elongatum exhibited the h...

Citrus can be propagated successfully through stem cutting. However, success of the propagation is depends on various internal as well external factors. The 2*7 factorial Randomized Complete Block Design (RCBD) experiment was conducted at Institute Agriculture and Animal Sciences, Paklihawa Campus, Rupandehi, Nepal from 22 November 2019 to 5 March 2020 assess interaction effect types cuttings i...

The relationship between the concentration of trichloroethylene (TCE) in the brain and changes in brain function, indicated by the amplitude of steady-state pattern-elicited visual evoked potentials (VEP), was evaluated in Long-Evans rats. VEPs were recorded from visual cortex following stimulation of the eyes and, thus, reflect the function of the afferent visual pathway and, in broad terms, m...

Abstract This research aims to determine the ability of Pluchea indica Less methanol extract as an inhibitor in low carbon steel corrosion 1 M hydrochloric acid media. HCl solution was reacted with P. leaves decelerate process oxidation iron (Fe) concentration variations 0 ppm, 500 1000 1500 and 2000 ppm immersion time 2, 4, 6 days. The level determined by loss weight method potentiodynamic pol...

The modifying effect of four dose levels of butylated hydroxytoluene (BHT) on liver and bladder carcinogenesis by A/-2-fluorenylacetamide (FAA) was studied in rats. FAA (200 ppm) was fed simultaneously with four levels of BHT (300, 1000, 3000, and 6000 ppm) to male F344 Fischer strain rats. Groups of animals were killed at 6, 12, 18, and 25 weeks. Hepatocellularaltered foci in the liver were id...

The modifying effect of four dose levels of butylated hydroxytoluene (BHT) on liver and bladder carcinogenesis by N-2-fluorenylacetamide (FAA) was studied in rats. FAA (200 ppm) was fed simultaneously with four levels of BHT (300, 1000, 3000, and 6000 ppm) to male F344 Fischer strain rats. Groups of animals were killed at 6, 12, 18, and 25 weeks. Hepatocellular-altered foci in the liver were id...

Fetal and neonatal iron deficiency results in cognitive impairments in adulthood despite prompt postnatal iron replenishment. To systematically determine whether abnormal expression and localization of proteins that regulate adult synaptic efficacy are involved, we used a quantitative proteomic approach (isobaric tags for relative and absolute quantitation, iTRAQ) and pathway analysis to identi...
