Rectangular bottom balance bars netting in a homogeneous flow is considered. It is shown that the calculation on traditional formulas in the self-drag area can lead to appreciable errors. Improved model allows correct account of local hydrodynamic drag force acting on the netting in the self-drag area the influence of various parameters on the shape and magnitude of effort is considered. Boundary value problem of equilibrium netting strips fixed nets is simply solved by numerical method in the Mathcad medium. Calculation results do not contradict the physical sense.

Lovage (Levisticum officinale L.) is a perennial herb belonging to the Umbelliferae family, with a characteristic earthy, celery-like flavour and it contains biologically active substances. For isolation of biologically active substances several solvents and extraction methods can be applied. Dried lovage seeds were extracted with six different solvents using different extraction methods. For all extracts, total phenolic, flavonoid content and DPPH˙, ABTS radical scavenging activity, and reducing power were determined using a spectrophotometric method. As the best extraction method for isolation of phenolic compounds and preventive inhibitor of lovage seeds ultrasound-assisted, but for antioxidants Soxhlet extraction can be chosen. While the best solvent for isolation of phenolic compounds and preventive inhibitor ethanol, but for antioxidants ethanol / water / acetic acid mixture can be chosen. Lovage seeds extracts have strong antioxidant activity, comparable to synthetic antioxidant.

The increasing popularity of minimally processed vegetables has been attributed to the health benefits associated with fresh produce as well as to the consumers’ demand for convenience provided by ready-to-eat products. Fresh shredded carrots, treated by immersion during 30±1 seconds with 1.5% hydrogen peroxide water solution, packaged in DuniForm PP trays (138x114x53 mm) and hermetically sealed by breathing polymer film BOPP PropafilmTM P2GAF, cellulose based biodegradable NatureFlex NVS. Polilactid BIO-PLA containers were used as well. Samples were stored at temperature +4±1 °C for 8 days. The object of this research is to study the effect of the treatment method with H2O2 on the quality evolution, during the storage period. To study the possible effects on the quality - colour intensity and sugars. As a control samples, non-processed carrots packaged in mentioned packaging materials were tested.

The maim requirements to normative feeding and keeping dogs are established. The fodder that is used in zonal centre of cynological gervis has a disbalance of nutrient compounds. The change of fodder is recommended. The trend to increase bony index and decrease prolixity index in male dogs is established. The signs of laryc paw, high paw, increase of bony indexes are showen, and hypertrophy of dogs skeleton is observed. The trend to breed degeneration of German shepherd is also observed. In order to preserve the gene pool and reduce the cost of puppies it is recommended to rent out their males to mate with pedigreed female.

In low-voltage shipboard power systems the use of neutral grounding resistor modeis allowed. However the known methods for the implementation of the grounding used in onshore net-works of medium voltage classes are not compatible with continuous monitoring of insulation resistance. Compatibility can be maintained by using separations capacitors. The developed method of neutral grounding for ship low-voltage electrical systems will limit the arc voltage while maintaining the possibility of continuous insulation resistance measurement of direct current.

The regional fishery is one of the key industries of the Kaliningrad region and it plays a significant role in the population food supply. Market reforms of 1990s led to the destruction of the fishing industry enterprises and efficiency reduction. After the crisis regional fishery complex had positive changes, but the overall dynamics of catches and fish processing is not ideal. Therefore the questions associated with the search of the main directions of its development and growth are very important. There are a number of significant problems hindering the development of this strategically important sector of the economy, which can be solved through government and business agreed cooperation. Sustainable development of the Kaliningrad fishery complex will create conditions to increase the gross regional product and food security of the region and the country as a whole.
