Organic compounds including seaweed extract were applied in organic production system and sustainable agriculture. One of these compounds is humic acid that was used widely in research and commercial programs. Humic acid is an organic acid obtained from humus and other natural resources with hormonal effects and improving nutrient absorption, increasing root and shoot biomass. In order to inves...

This study was conducted to evaluate the effects of exogenous polyamines, isopropyl ester, 2, 4-D and naphthalene acetamide application on yield and quality of date palm of ‘Kabkab’ cultivar. The inflorescences sprayed with 2, 4-D isopropylester (0, 10, and 20 mg L-1), naphthalene acetamide (0, 80, and 120 mg L-1), putrescence and spermidine (0, 0.1, and 1.0 mM), three or six weeks after pollin...

Let H be a Krull monoid with finite class group G such that every contains prime divisor. We consider the system L(H) of all sets lengths and study when or is contained in L(H?) H? G?, divisors classes Davenport constant D(G?)=D(G). Among others, we show if either cyclic order m?7 an elementary 2-group rank m?1?6, G? any which non-isomorphic to but D(G?)=D(G), then systems are incomparable.

Recent studies indicate that co-planar 3,3',4,4',5-pentachlorobiphenyl (PCB) congeners or their metabolites may disrupt thyroid function in fishes. Although co-planar PCB have been detected at microgram per kilogram levels in fish from contaminated areas, few studies have examined mechanisms whereby, co-planar PCBs may alter thyroid function in fish. We treated immature lake trout by intraperit...

The investigation aimed to study the effect of foliar application chemicals on plant canopy, vegetative growth and flowering, as well overall appearance Ixora chinensis plants grown in pot. Application salicylic acid, benzyl adenine silicon at different concentrations significantly influenced growth, pigments compared untreated (control). Plants treated with 10 mg/l 20 acid showed significant i...
