Microelements are essential for the function of innate immune system. A deficiency in zinc or copper results an increased susceptibility to bacterial infections.

In this paper microsensing elements with thin piezoelectric films are presented. Three different materials from the basic types – ceramic, metal oxide and polymer, in microsystems for environment parameters control are used. Zinc oxide (ZnO) and lead zirconium titanate (PZT) by sputtering technology from hot targets are deposited. The optimal parameters of the process and thickness of the layer...

People are exposed to heavy metals both in an occupational and natural environment. The most pronounced effects of heavy metals result from their interaction with cellular genetic material packed in form of chromatin. Heavy metals influence chromatin, mimicking and substituting natural microelements in various processes taking place in the cell, or interacting chemically with nuclear components...

New criteria (full physiological value and preservation of the properties of drinking water) are scientifically substantiated. Also discussed are indices (minimal admissible and optimal levels of basic water mineralization and calcium content, standards of microelements such as boron and bromine content, content of individual groups of microorganisms, water temperature) for evaluating the quali...

Enterosorbents (oral sorbents) on a basis of spherically granulated synthetic (d = 0.3-0.6 mm) and fruit stones (irregular granules d = 0.3-2 mm) carbons, and also the activated carbon fibers represent high purity and high porous materials with controllable surface chemistry. In some cases in a superficial layer of such carbons there are set amounts and types of heteroatoms nitrogen and oxygen,...

to find out the effects of urea and animal manure as pellet and some microelements on total dry matter and physiological indices of medicinal pumpkin a split plot experimental design based on a randomized complete block with three replicates was conducted at university of tehran, college of abouraihan. the animal manure and urea as pellet with four levels (150 kg urea, 50 kg urea+3.5 tone anima...

The article presents a plasma chemical technology for processing solid fuels, using examples of bituminous and brown coals. Thermodynamic and experimental investigation of the technology was made. The technology allows producing synthesis gas from the coal organic mass and valuable components (technical silicon, ferrosilicon, aluminum, and carbon silicon, as well as microelements of rare metals...

Most medicinal plants are flowering plants and they also serve as ornamental plants. Measurement of trace element content in medicinal plants, drugs and extracts may be relevant in view of e.g. human health, animal health and environmental relations. This fact has a great significance since about half of the plant drugs available in the trade originate from natural habitats and the element cont...

We introduce a simple and robust method for fabricating hierarchical fibrillar arrays based on polymer micropillar (microPLR) arrays decorated with ZnO nanowires (NWs) on mechanically flexible substrates. The hierarchical fibrillar arrays are fabricated by replica molding of polymer microPLR arrays on microfabricated silicon templates and subsequent solution-based growth of ZnO NWs. Fine contro...

With a large and growing demand in the market, rapeseed (Brassica napus subsp. napus.) is crop with relatively high requirements for macronutrient fertilization. The aim of experiment was to study effect mineral fertilization different doses nitrogen phosphorus on accumulation microelements vegetative organs grains oilseed rape plants.The carried out long-term experimental fields SCDA Livada.
