Metal Oxide Varistors are today used for manufacturing state of the art overvoltage protection equipment, at any voltage level, being one of the most common power electronic devices existing on the market. They are widely used because they have a very high non-linear dependence between the applied voltage and the resulting current, and a relatively high energy absorption capability in case of normal overvoltage shocks or even in case of permanent overvoltages. Researches could be carried out both for finding a new...

Pruning is one of the most important agro-technical measures during cultivation of grapes that affects directly in increasing the quantity and quality of grapes and wine.

Thermal pollution is considered to be one of the physical water pollution types that is caused by dumping of water heated by the units of industrial, thermoelectric and nuclear power stations. This type of pollution is characterised by the increase of water temperature higher than the natural level. At the places where heated water is dumped there are zones with water temperature higher than in the whole reservoir: about + 12пїЅ ? in winter and + 30пїЅ ? in summer. This fact results into the increased amount of or...

Extra-heavy oil is considered as one of alternative energy sources mainly because of reserve potentials, rich in organic compounds and rare transition metals like V and Ni. Extraction from this hydrocarbon resource has always been a challenge due to high oil viscosity and as a result low mobility within porous media. Conventionally the production from extra-heavy oil reservoirs is achieved by thermal methods such as SAGD, CSS, Insitu combustion, etc. However, these techniques do not consider the post productionsпї...

In historical city centers cobbled roadways are currently being used in the reconstructions of roads. Cobbled roadways are being built also in new construction for example parking lots, sidewalks and bike paths. Cobbled aprons are often built around a central island on roundabouts. Elevated transverse thresholds or pillows made of cobblestones are popular as elements for traffic calming in residential urban areas. A prerequisite for perfect function of these cobbled surfaces is the adherence to the correct technol...

The paper concerns the pores systems characterization of the Miocene mudstone samples provided by mercury injection capillary pressure (MICP) method. This analysis is the progressive intrusion of mercury into a porous structure under stringently controlled pressure. Since mercury does not wet most substances and does not spontaneously penetrate pores by capillary action, it must be forced into the pores by the application of external pressure. The required equilibrated pressure is inversely proportional to the siz...

The aim of this article is to study astronomical refraction anomalies. Back in 1925 Grachev and Banahevich found systematic errors in meridian observations depending on zenithal distance. Grachev suggested that these refraction anomalies arise from the inclination of the Earth's surface to the South. The airstratas of the same density were considered as parallel to the Earth's surface. But the analysis of latitude observations from the Bamberg and ZTL-180 telescopes showed there were significant systematic errors ...

When building the foundations of a machine tool, demands must be placed on high quality and, above all, on their stability during their entire lifetime. In practice, however, it shows that these requirements are not always fully met on the customerпїЅs side when laying foundations. In the course of working, these foundations are subsequently damaged and their uneven decline occurs, which results in a change of the machine alignment, and thus it also influences the accuracy of production. For the supplier of the ma...

Specific models and storage technologies which is possible to save domain semantics are required to create configurable information systems. This is why modern researchers talk about the high cost of domain models in comparison with a program code. But they don't suggest any approaches for including this model as a component of the system itself. Existing approaches for domain modeling during the transition to final stages of a system life cycle tend to lose the semantic component of the data. They only allow to p...

For a long time, coal mining in the Eastern Donbass was the most powerful factor affecting the natural environment. The most significant were the natural underground and surface waters. Their pollution was due to mixing with highly mineralized man-made mine waters, which seeped through the rock mass, polluting the underground hydrosphere, and at the same time, as a result of pumping out of mines, fell into rivers. As a result of the closure of most coal mines in the region in the 1990s, the processes of hydrospher...
