The tetra-nuclear title compound, [Cu(2)Ti(2)(C(6)H(6)NO(6))(2)O(O(2))(2)(H(2)O)(10)]·7H(2)O, lies about a twofold rotation axis that passes through the bridging oxide atom. The titanium atom is N,O,O',O''-chelated by the nitrilo-triacetate and O,O'-chelated by the peroidxo group and is coordinated to the bridging O atom in an overall penta-gonal-bipyramidal geometry. The O atom of one of the c...

iran is a rather wide country, and, as a rule, the chrage per one call in s. t .d . (subscriber trunk dialing ) is required more compared with a local call , so, just after the opening of the std service widely in national telephone network, unconcerned use of the s. t. d. service has been caused on an incon- ceivable increase in telephone charge of th subscriber. this is a common problem for a...

A coupled binuclear copper active site is present in a wide variety of proteins and enzymes which perform different biological functions utilizing 0,. In the multicopper oxidases, the Type 2 and Type 3 centers comprise a trinuclear Cu cluster which represents the active site for the multielectron reduction of 0,. A coupled binuclear copper active site is present in a wide variety of proteins an...

In the title complex, [Pr(2)(C(2)O(4))(3)(H(2)O)(4)](n), the two independent Pr(III) ions are both nine-coordinated in a distorted monocapped square-anti-prismatic geometry by seven O atoms from four oxalate ligands and two water mol-ecules. The Pr(III) ions are bridged by the oxalate ligands, forming a layer parallel to (001). O-H⋯O hydrogen bonds connect the layers.

Merremia emarginata plants were treated with different plant growth regulators (PGRs): naphthyl acetic acid (NAA), phenyl acetic acid (PAA) and gibberellic acid (GA 3). To determine the role of wall stiffening enzymes in internode elongation, IAA oxidase and peroxidase in the presence of different hydrogen donors like caffeic acid, chlorogenic acid and guaiacol were assayed. The levels of total...

Extra-virgin olive oil is an integral ingredient of the Mediterranean diet, and it has been suggested that its high consumption has beneficial effects on human health. Its protective effect, in particular against the development of CVD, has been related not only to the high content of oleic acid, but also to the antioxidant and anti-inflammatory properties of polyphenols. In order to verify the...

Soils contaminated with low levels of heavy metals and other trace elements are now frequently used for vegetable growing. In this situation, heavy metals and trace elements from these polluted soils may accumulate in the agricultural plants being grown in them and thereby enter the human food chain. The objectives of this study are to elucidate the effects of growth conditions, manipulated by ...
