15-Hydroxyeicosatetraenoic acid (HETE), as a mammalian biologically active metabolite, has anticarcinogenic effect. The conditions of producing 15-HETE from arachidonic acid by using soybean lipoxygenase were optimal at pH 8.5 and 20°C with 9 g/l arachidonic acid, 54.4 U/ml soybean lipoxygenase, and 4% methanol. Under these optimized conditions, the enzyme produced 9.5 g/l 15-HETE after 25 min,...

is the need to share and utilize it among the members of the scientific community. The concept of science, either basic or applied, implicates its utility for the development of the society. This is the reason why no discovery should stay private and the public access needs to be established. It is a kind of exchange which benefits the authors and the scientific community. The investigators gai...

alstroemeria flower is one of the most important cut flowers in the world. some materials can increase longevity of cut flowers. the aim of this research was evaluating the effect of some chemical solutions on postharvest alstroemeria (cv. stratus) cut flowers. this experiment was conducted with two factors of sucrose at four concentrations, 0, 5, 10 and 15 g/l and salicylic acid (sa) at four c...

Nowadays, energy consumption is massively increasing in the world. The production of biofuels from microalgae has received considerable attention recently and potential to supplant fossil fuels. Recent research focuses on developing as an alternative fuel. This will focus evaluating effect indole-3-acetic acid (IAA) growth metabolite Euglena sp. methods used this study started with a medium pre...

We give a new proof of the fact that every planar graph is 5choosable, and use it to show that every graph drawn in the plane so that the distance between every pair of crossings is at least 15 is 5-choosable. At the same time we may allow some vertices to have lists of size four only, as long as they are far apart and far from the crossings. Thomassen [5] gave a strikingly beautiful proof that...

Cadmium can be found in wastewater in high concentrations and can cause dangerous effect on aqueous environment and human health. At present, many methods have been used to heavy metals removal. Among this clean up techniques, adsorption techniques by using low-cost adsorbent are more considerable. In this study, batch adsorption experiments were conducted for removal of cadmium ions from a...

Let $$p \geqslant 3$$ be a prime integer and, for $$l 1$$ , let $$G \cong {{\mathbb {Z}}}_{p}^{l}$$ group of conformal automorphisms some closed Riemann surface S genus $$g 2$$ . By the Riemann–Hurwitz formula, either \leqslant g+1$$ or $$p=2\,g+1$$ If $$l=1$$ and then S/G is sphere with exactly three cone points if moreover 11$$ G unique p-Sylow subgroup $$\textrm{Aut}\hspace{0.55542pt}(S)$$ $...
