Modern town and regional planning was shaped institutionally under the conditions of industrialisation and the associated growth in the economy and population in towns and industrial agglomerations. The aim is to manage this growth and create the conditions for its continuance with the smallest possible negative impacts on conditions. The main resources for ensuring problem-free growth consists of seeking out suitable areas for the construction of new housing and industrial plants, and the regulation of constructi...

Currently, for the development of industry, it is very important and relevant to create materials with improved properties and parameters. The creation of composite materials based on polymers is promising. YBa2Cu3O6+x (YBCO) particles, according to the Le Chatelier principle, absorb oxygen atoms from the surrounding macromolecules of the matrix, causing a decrease in the volume of the polymer. The effect of nanodisperse fillers from YBa2Cu3O6+x in polyimide composite films on the interactions between macromolecul...

Interest in polymer materials with a metallized coating is growing every day. Polyimide (PI) with high heat-resistant properties and a low coefficient of thermal expansion is one of the promising materials for metallization. Polyimide metallized films are used as highly reflective materials for space technologies, and they are also used to produce materials for adaptive and flexible optical devices. Polyimides have good dielectric properties. The process of metallization of polyimide films is studied and the optim...

Progress in new technologies brings with it unknown dangers and risks. The biggest development of the last few years is the use and production of fine and ultrafine particles (aerodynamic diameter less than 2.5 ?m), which, according to new studies, may have a negative impact on human health. It is very important to deal with this problem, especially from the point of view of workers who are at the front line of contact with these new materials, and it means that they are also at the greatest risk. There is yet no ...

Wheat (Triticum L.) is a cereal which has a unique role in the global economy due to its technological and production value. The aim of this paper was to highlight the variation of the amount of mineral substances from thirty one varieties of wheat grains cultivated in Romania, from various origins such as: Romanian, German, French, Austrian, etc. Twenty-four grains samples were of common wheat (Triticum aestivum), two wheat samples were of Triticum monococcum and five wheat samples were of Triticum spelta. All th...

The blood parameters of rats under repeated inhalation exposure to copper oxide (II) nanoparticles aerosol (CuO NPs) compared to the microdispersed analogue (CuO MPs) have been studied and evaluated. According to the results of the study of the size, specific surface area, and total volume of pores, it was found that the sample under test is a nanomaterial. Rats were exposed to aerosols of aqueous suspensions of CuO NPs and CuO MPs for 10 days at 4 h/day in an inhalation system with a full-body chamber. The actual...

Currently, the task of modifying the technological properties of mineral raw materials for the construction industry, road construction and the oil industry based on clay in order to obtain the specified characteristics, provided that the production cost is reduced, is relevant. The results of the study of the acid-base characteristics of the clay suspension surface without and in the presence of modifying additives that improve the plasticity of the mass, reduce shrinkage and crack formation in baked ceramics are...
