Palladium-copper alloys continue to be of interest for hydrogen membrane applications because of their high catalytic activity for hydrogen dissociation, high hydrogen permeability, robustness, and degradation resistance in the presence of sulfur-containing compounds. This sulfur tolerance makes these alloys attractive for membrane applications where sulfur compounds are likely to be present, s...

Uterotropic Activity of DDT in Rats and Mink and Its Influence on Reproduction in the Rat. DUBY, R . T., TRAVIS, H. F., and TERRILL, C. E. (1971). Toxicol. Appl. Pharmacal. 18, 348-355. The injection of o,p'-DDT increased uterine weights in intact immature rats, and in intact and castrate immature minlc The p,p' -isomer had only slight activity while the uterotropic activity of technical DDT wa...

A new strategy to discriminate four types of hazardous gases is proposed in this research. Through modulating the operating temperature and the processing response signal with a pattern recognition algorithm, a gas sensor consisting of a single sensing electrode, i.e., ZnO/In₂O₃ composite, is designed to differentiate NO₂, NH₃, C₃H₆, CO within the level of 50-400 ppm. Results indicate that with...

The oil of Schinus molle exhibited the maximum fungitoxic activity during the screening of some essential oils against some common storage and animal pathogenic fungi. It showed absolute toxicity against animal pathogens and mild activity against storage fungi. The effective concentrations of the oil varied from 200 to 900 ppm. The toxicity of the oil persisted up to 80 degrees C and 90 days of...

The purpose of the present study was to clarify the potentiality of acidic fluoride solution in treating peri-implantitis. We examined bactericidal activity of fluoride solution against periodontal pathogens; and evaluated the effects of fluoride on titanium, and the effects on cell proliferation and differentiation of rat bone marrow cells on the fluoride-treated titanium. Aggregatibacter acti...

It is crucial to develop new bottom-up fabrication methods with control over the physical properties of active materials produce high-performance devices. This article reports well-controlled, without seed layer and site-selective hydrothermal method ZnO bridging nanowires sensors. By controlling growth environment, performance sensor became more efficient. The presented on-chip nanowire enhanc...

Metallic monoliths were prepared by anodized aluminum-scale pilot plant, using sulfuric acid as electrolyte. Anodisation tests were conducted at different times and different temperatures of the electrolytic bath. Aluminum monolith anodized at 40oC for 30 min was selected for catalysts support. The monoliths were impregnated by two methods: i) impregnation in two stages using two Mn salts in an...

Gradients in elevation impose changes environmental conditions, which turn modulate species distribution and abundance as well the interactions they maintain. Along gradient, interacting (e.g., predators, parasitoids) can respond to different ways. This study aims investigate how egg parasitism of a forest pest, pine processionary moth (PPM), Thaumetopoea pityocampa, vary along an elevational g...

Fiber-optic sensors were developed for monitoring dissolved carbon dioxide in water samples in the 0 to 900 ppm concentration range. A pH-sensitive fluorescent dye (HPTS) was reacted with a cationic quaternary ammonium salt to form an ion pair which was electrostatically bound to the surface of particles of aminocellulose which then were dispersed into a gas-permeable silicone polymer. The gree...
