By ST u’ iIsLAw SZMIGIELSKI AND JOANNA Ln’w T HE PHYSIOLOGIC and biochemical role of zinc (Zn), as a cofactor of many important enzymes ( carboxypeptidase, dehydrogenases, alkaline phosphate, carboanhydrase) is now well established, but our present knowledge of zinc metabolism and transport in the human body is still incomplete. Vallee1 estimated Zn content in whole blood at 880 gamma/100 ml. H...

In order to study the effect of zeolite and biologic fertilizers application under different irrigation regime on yield and quantitative traits in sugar beet, a research project was conducted according split-split plot experiment based on randomized complete block design with four replicates. The main factor included irrigation regime at two levels (Normal and stress), sub factor included zeoli...

In order to continue our previous studies on some Viola species from Romania, we have analysed for the first time some active principles from aerial parts of V. declinata Waldst. et Kit. We have performed gravimetric methods for saponins and mucilages, and spectrophotometric determinations and HPLC analysis of carotenoids. We established the content in saponins (4.40%), mucilages (10.26%), and ...

We have synthesized a series of cluster assembled materials in which the building blocks are As(7)(3-) clusters linked by group 12 metals, Zn, Cd and Hg, to investigate the effect of covalent linkers on the band gap energy. The synthesized assemblies include zero dimensional assemblies of [Zn(As(7))(2)](4-), [Cd(As(7))(2)](4-), [Hg(2)(As(7))(2)](4-), and [HgAsAs(14)](3-) in which the clusters a...

In order to determine effect salicylic acid and Zn on characteristics of pistachio nut (Pistacia vera L. cv. Owhadi), the experiment was carried out as factorial in the framework of CRD design with three replications. The results showed that salicylic acid and Zn increased nut fresh weight and decreased blank nut percentage. The application of salicylic acid decreased splitting percentage and k...

Fruits and vegetables are considered as good source of functional foods due to their health benefits nutritional content. Dietary constituents fruits vegetable commonly available has significant application in management chronic diseases such as; coronary heart disease, stroke, cancer diabetes, many medicinal purposes, control excess weight obesity high fiber content present. Many phenolic comp...

The increase of sucrase activity in homogenates of jejunum and ileum of suckling rats after cortisone administration has been investigated. Serial tissue sections of villi and crypts were also assayed for sucrase activity and these results were compared with the migration of cells labelled with [(3)H]thymidine along the villus. By using a low dose of cortisone (0.5mg/day per 100g body wt.) it w...

This paper presents a few examples of the application of electron back-scatter diffraction (EBSD) to solidification problems. For directionally solidified Al-Zn samples, this technique could reveal the change in dendrite growth directions from <100> to <110> as the composition of zinc increases from 5 to 90 wt%. The corresponding texture evolution and grain selection mechanisms were also examin...
