Recent online translators for languages without a significant number of speakers cannot reach the quality of the translators for languages such as English, Spanish, and French, etc. The great number of users of these common languages means a higher possibility of correction of an inaccurate translation. For those languages with around ten, twenty million speakers, translators cannot gain such effectivity. All the documents produced in the EU must be translated into all the languages of the EU. Translators that hav...

From geological point of view tailings dam materials are different compared to regular types of soil. In mechanical aspects it is material that has regular mechanical properties like shear parameters and deformation moduli. Based on the huge expansion of the hardening soil model in the last 20 years, this paper discusses the E50 modulus and its relation to some of the well-known physical soil properties. Expressions of E50 in respect to water content, grain size distribution, void ration, site depth and confining ...

One of the important environmental problems in the development of copper ore deposits is the pollution of biological objects located in the zone of influence of mining enterprises. This problem is most relevant for sulfide copper ore deposits, which include a number of heavy metals that are toxic to the environment. Geochemical processes, occurring during the development of such deposits, lead to the entry of heavy metals into the surrounding landscape and their accumulation in the grassy vegetation. It is necessa...

Poultry meat and table eggs are known to be a popular food items all over the world. The nutritional value of poultry white meat is of great value over the red meat. It contains considerable amount of protein, minerals, vitamins, and fat. In order to ensure a good quality of poultry products, the flock should be a good health and free from infectious agents. Antibiotics were widely used to prevent diseases in poultry flocks. However, using antibiotics for long time may lead to microbes that are resistant to drugs....

In accordance with the hypothesis of cold homogeneous accretion, it is usually assumed that the Earth?s core and mantle resulted from the gravitational separation of iron and silicate particles in its interior. According to this scenario, the core and mantle temperatures should not differ significantly. Therefore, the reason for mantle convection is difficult to explain. Recent data on the rapid accretion of planets, on the existence of magmatic fractionation trends in mantle xenoliths and in rocks of the crystall...

In-situ combustion (ISC) is an enhanced oil recovery process where heat and flus gases (combustion gases) are generated by burning a portion of crude oil to reduce oil viscosity and pressurize the system in the reservoir. Overall, in this method, air is injected to the reservoir, after the ignition process (self-ignition or artificial ignition), a combustion front is formed and moves toward the producer well. Nowadays, using metal oxide catalysts is considered as a possible and feasible route to improve the oxidat...

Along the north-eastern and eastern margins of the Siberian platform extends the foreland zone of the Verkhoyansk fold-and-thrust belt (VFTB) to the west of which is the Priverkhoyansk foredeep. On the north, the platform is bounded by the Olenek folded zone with the Lena-Anabar basin located to its south. Various authors identified a number of deformational events in the Late Mesozoic tectonic history of the region, of which the nature, kinematics and relationships are as yet poorly studied.

During High Carbon Ferromanganese production as well as other reduction processes, the chemical composition of the feed plays a crucial role on the quality of the products. It is believed that the reduction from high manganese oxides to their lower oxides during HCFeMn production, the transitional phases that form in the prereduction zone and reduction zone are very influential on the coke-bed zone behavior. Data on acidic manganese ores use are available. However, on the basic manganese ores especially the South ...

In this study we performed a comparative analysis of the flavonoid compounds found in the composition of some species belonging to the Cucurbitaceae family, namely: cucumber (Cucumis sativus), bitter melor (Momordica charantia), zucchini or courgette (Cucurbita pepo) and horned melon (Cucumis metuliferus). The flavonoids in these species were identified by high performance liquid chromatography. The Cucumis metuliferus plant extract had the highest content in phenolic compounds (14.424 mg/L), while the Cucumis sat...

One of the most important alternatives in sewage sludge ash management is the recovery of essential elements such as phosphorus. Phosphorus is an important element for plants, food supply, human health and industry. Phosphorus is a non-regenerative resource and therefore it is important to find alternative sources to recover phosphorus. Phosphorus recovery as struvite (NH4MgPO4.6H2O) from sewage sludge ash has attracted special attention in the last decade due to the potential to be used as an ecologic fertilizer....

The Upper Devonian shales are predominantly carbonate, carbonate-siliceous thin-layer rocks with a high content of organic matter. Considered formation is widespread within the Volga-Ural and Timan-Pechora basins in the European part of Russia. Various estimations show that the hydrocarbon resources of the Upper Devonian shales range between hundreds of millions to billions of tons of oil. However, recovery of such hydrocarbons is significantly constrained due to the high heterogeneity and complex structure of roc...

Due to their properties and low production costs, plastics have replaced a number of construction materials and are being used more and more. To maximize the potential of plastics at the final stage of their life, you need to choose the right way to manage the resulting waste. In accordance with Circular Economy, the first form of using this waste should be material recycling, energy recovery may be an alternative to this method of management. It is unacceptable that in the era of today's technology this type of w...

In the development of a sustainable society and an active approach to environmental protection, it is essential to focus on building energy efficiency and its increasing. Within the member states of the European Union, the process of increasing the energy performance of buildings is ensured by increasing the requirements for new buildings through legal and technical standards. This process is supported financially by various EU funding programs. One of the useful helpers in spreading awareness of the energy perfor...

The added value generated by the fisheries sector in 2017 was only 0.15% of the total value added in Latvia, in the meantime its significance in external trade was higher, as the sector accounted for 1.8% of the total value of export production (EUR 206 million). The export capacity of the fishing sub-sector is mostly determined by the development of the fish processing sub-sector. Canned fish form 35% of the Latvian exports but this product group faces challenges of product and market reorientation due to decreas...
