Gouramy cultivation has obstacles in its development, one of which is disease. Disease attack fish farming activities a serious obstacle. The purpose this research was to determine the effect cattapa leaf solution (Terminalia goramy) on treatment juvenile gouramy (Osphronemus infected with fungal pathogen Saprolegnia sp. This study used completely randomized design method 5 treatments and 3 rep...

Groups of 48 males and 48 female rats were given diets containing 0 (control), 500, 2000 or 10,000 ppm Chocolate Brown HT for 2 years. These treatments had no adverse effect on mortality, body-weight gain, food or water consumption, haematology, renal function, serum constituents, organ weight or histopathology. From the incidence of tumours observed in the control and test animals it is conclu...

A sensor for carbon monoxide detection based on broadband absorption spectroscopy with a gas correlation filter is developed using a miniaturized light source and detector without the need of a mechanical chopper to alternate between two gas correlation cells into the optical path. Measurements were conducted using calibrated CO/N2 mixtures and sampled combustion products from a diffusion flame...

The current study investigates the energy consumption and corresponding global warming potential (GWP) of tellurium recovery from multimetal solution by use a tailored electrochemical approach based on electrodeposition-redox replacement (EDRR). A three-electrode cell was used to recover Te synthetically prepared pregnant leach similar PLS leached Doré slag (30% aqua regia, [Cu] = 3.9 g/L, [Bi]...

Formaldehyde (FA) is a common source of allergic contact dermatitis. The source of FA exposure is often difficult to be elucidated. It is generally agreed that the most frequent FA exposure source is cosmetics. The 2,4-dinitrophenyhydrazine (2,4-DNPH) derivatization method followed by high performance liquid chromatography (HPLC) analysis was used to determine the FA content in some commercial ...

In this study, three different compositions of ZnO and TiO₂ powders were cold compressed and then heated at 1250 °C for five hours. The samples were ground to powder form. The powders were mixed with 5 wt % of polyvinyl butyral (PVB) as binder and 1.5 wt % carbon black and ethylene-glyco-lmono-butyl-ether as a solvent to form screen-printed pastes. The prepared pastes were screen printed on the...

Efficacy of thiamethoxam (Cruiser) and imidacloprid (Gaucho) were evaluated as seed treatments for controlling European corn borer, Ostrinia nubilalis (Hübner) and Indianmeal moth, Plodia interpunctella (Hübner) larvae in stored grain. At approximately 22-26 degrees C, all fifth instar European corn borers died after two or 4 d of exposure to corn treated with 250 and 500 ppm thiamethoxam, resp...

Biofilm-forming marine bacterium Pseudomonas aeruginosa JP-11 was isolated from coastal marine sediment of Paradeep Port, Odisha, East Coast, India, which resisted up to 1,000 ppm of cadmium (Cd) as cadmium chloride in aerobic conditions with a minimal inhibitory concentration of 1,250 ppm. Biomass and extracellular polymeric substances (EPS) secreted by the cells effectively removed 58.760 ± 1...

BACKGROUND Hard water is associated with atopic dermatitis (eczema). We wanted to determine if a baby cleanser and its individual components altered free ionized calcium (Ca2+) in a simulated hard water baby bath. For these studies, an in vitro determination of free Ca2+ in a simulated hard water baby bath, and an in vivo exploratory study of free Ca2+ absorption into skin from hard water were ...
