The Verkhoyansk fold-and-thrust belt (VFTB), composed of terrigenous-carbonate rocks of the Upper Proterozoic, Paleozoic and Mesozoic age and formed in the Late Mesozoic time, stretches along the north-eastern and eastern framing of the Siberian platform. Studies were carried out (from south to north) in the Kuranakh and Kharaulakh segments of the Western-Verkhoyansk sector of VFTB and in the Olenek sector of VFTB. Structures of the Kuranakh and Kharaulakh segments have submeridional strike, and the Olenek ? subla...

The breeding value of the selection candidates is the criterion on which the best individuals are retained for breeding, corresponding to proportion of the selected individuals. When the livestock is grown in an ecological system, the only leverage by which meat production can be increased is the use of the individuals with the highest genetic merit. The average of breeding values of selected individuals coincides with genetic progression on generation, implicitly with the growing production in the considered trai...

The quality of water sources used for drinking water production is highly varied. Many problems arise in groundwater due to the content of hydrogen sulfide and ammonia. Thei presence of its in water affects the organoleptic properties, in disosolved form the hydrogen sulphide confering undesirable taste and irritating rotten egg smell which make it unpalatable. Ingestion of sulphides through drinking water can result in stomach discomfort, nausea and vomiting. Ammonia in concentration above 1.5 mg/L can cause odou...

In the current work, a series of poly(sodium acrylate)-co-acrylamide (polyNaA-co-AAm/pectin and polyNaA-co-AAm/bentonite) superabsorbent composites were prepared using pectin, bentonite, acrylamide and acrylic acid (AA) in the presence of N,N-methylenebisacrylamide (MBAAm) as cross-linker and a mixture of ammonium persulfate and TEMED as initiator.

The analysis of bottom sediment quality is an important yet sensitive issue. The anthropological influences (i.e., urban, industrial and agricultural activities) as well as the natural processes (i.e., changes in precipitation amounts, erosion and weathering of crustal materials) degrade surface water quality and impair its use for drinking, industrial, agricultural, recreational and other purposes. Due to spatial and temporal variations in water chemistry, a monitoring program that provides a representative and r...

Constructive details of welded steel industrial structures involve critical areas in the structure. A welded steel structure behaves differently toward a steel structure made of laminated steel profiles in a pervasive corrosive environment. Details of the joining of the steel elements must correspond primarily to the strength of the welded steel structure but also to the impact of the corrosive environment, that is to say, some details must be chosen to fade the effect of the corrosive environment. The paper will ...

The reliable determination of solid material thermal properties (thermal conductivity, thermal diffusivity and heat capacity) are significant for various industries. Knowledge of thermophysical characteristics of reservoir rocks is essential in developing high viscous oil deposits by thermal methods. One of the biggest problems in experimental investigation of thermophysical properties concerns with measurement errors due to multidimensional character of thermal flow (generally, in most cases, one-dimensional theo...

Agricultural production is expected to increase in the world, which will be determined by the growing population and the rising demand for food, feed, fibre and energy. However, an increase in agricultural output could result in an increase in greenhouse gas (GHG) emissions from the agricultural sector. In order to avoid it, emissions have to be ?decoupled? from agricultural production, i.e. it is necessary to decrease the GHG emissions per unit of agricultural production. This is particularly important for Latvia...
