This article is devoted to the study of small mammal communities (species composition, daily activity and spatial distribution) in the agrocoenosis. The fields of winter crops that were surrounded by similar fields or by winter crops with meadow vegetation were researched. The Mus musculus became the dominant species in the winter crops agrocoenosis. The R. Sylvaemus living near the border with field-protective forest belts (and 25 meters field around) are subdominant group. Marked single finds Mus musculus in the forest and R. Sylvaemus in the field (at a distance before 50 meters). It is shown that the presence of meadow vegetation increases the species diversity of mice in the agrocoenosis. In the middle of this field a subdominantion group is Microtus arvalis s.l. and Cricetulus migratorius. The both species prefer a neighborhood with meadow vegetation. The method of recapture, followed by labeling with animals, made it possible to fix the movement for a distance of about 400 m. during the night (maximum values were males Mus musculus). The activity of small mammals in the winter crops was timed to coincide with the day-night cycles, with high activity from 01:00 to 04:00 am, and minimum activity after 09:00 hours of the morning before 08:00 pm

The results of the study presented showed that predator mite Ph. persimilis exhibited high food preference of the larval stage (30,2% of the total number consumed) compared to the egg (20,5%), nymph (13,4%) and adult (10,1%) stages of two spotted spider mite T. urticae. The functional response of Ph. persimilis feeding on eggs and adults of T. urticae was described by the Type II curve. At a maximum density of 60 prey per leaf disc, Ph. persimilis consumed an average of 22.8 eggs and 3.2 adults over an eight-hour period. Calculated time for handling of the prey by Ph. persimilis was on the average 0.074 hours (4.4 minutes) and 3.2 hours for T. urticae eggs and adults respectively. The mean number of T. urticae eggs consumed by Ph. persimilis progressively increased with the increase of the prey density, but the rate of predation (number of eggs consumed/prey density) decreased from 0.5 to 0.3 with the increasing of prey density. The mean number of adult T. urticae consumed by Ph. persimilis at densities of 20, 40 and 60 per leaf disk remained relatively constant. But the rate of predation decreased from 0.09 to 0.04 with increasing of prey density. The experiments showed that regardless of the strategy utilized by the predator it was the one that was efficient for the predator survival
The article explains the importance of the transport process when performing repair jobs of asphalt roads. The scheme of the technological process was drawn up; job steps were identified, while the latter may be characterized by non-productive downtime of transport as well as that one of technological machines. We have analyzed the following steps of the flowchart of the road concrete mix transportation: the preparation of the road concrete mix for transportation, loading, transportation, unloading, laying and packing. The transportation of goods starts at the working site of their production and ends at the site of their consumption. The transportation process is a multistep and multioperational process having the greater diversity of technological, operational and economic operations, which must be correctly organized. It is extremely important to deliver the road concrete mix of coating plant (OP) just in time, while avoiding the unproductive idle standing of the equipment, the deterioration of the mixture, as well as performing the job steps at minimum transportation cost savings. The successful combining of the steps of the concept organization of the road concrete mix transportation (coating plant, asphalt laying step, transportation step) will improve the performance and will provide the reduction of the job cost. One must perform the coordination of job steps on different road sections using information technologies and communication facility
The key stage of clonal micropropagation, the micropropagation sensu stricto, affords to increase the propagation index for plants, especially perennials. In this study, we consider ways to optimize clonal micropropagation of remontant raspberry cultivars. It is found that microsprout regeneration rate is 78,5–96,0 % on the multiplication s. str. stage. The most multipurpose nutrient medium is selected with containing 0,5 mg/l both of BAP and GK. When one uses this medium, regeneration rate runs 79,0–94,0% depending on genotype with sprout high running 24,8–32,7 mm and sprout number – 1,2–2,2 per node. The optimal duration of growing cycle is 30 days with the propagation index within 6,6–7,8, depending of genotype
To the present stage, the process of becoming contract soldier professionals lasts up to 10 years or more, which is impermissible for the Armed Forces of the Russian Federation. One of the elements of a professional orientation of soldiers under contract is its evaluation. In the study, the authors have proposed evaluation methodology of professional orientation of contract soldiers. The validity and reliability assessment of the proposed methodic was carried out in two stages: stage 1 - respondents survey according to the methodic of M. Rokeach and getting their individual profiles; stage 2 - predicting the level of respondents professional military orientation, based on the assessment of proximity (conformity) of the respondents' individual profiles of value orientations to owned reference profiles. The evaluation of the internal (criterion) validity technique was performed as assessing the validity of the relationship between the influence and the observed results and the possibility to use this relationship to predict respondent's actions in future. Reliability of the methodic was assessed by three indicators. For all the indications we have obtained the results, showing the retest reliability of the proposed methodology of evaluation of military-professional orientation
The aim of this study is the substantiation of recreational zones in the mountain forests for walking tourists. The article contains a functional zoning, design and spatial solution of landscapes of these zones. The aesthetic and recreational value of forests recreational areas increases the implementation of thinning. Implementation of thinning in the territory of the forest zone allocates places for relaxing and walking. This is the basis of functional separation of recreational areas. Coordinates of the objects of recreational areas (inputs and outputs, the center of the composition, toilets, natural monuments, gazebos, crossing trails and wooden sculptures) are determined using GPS satnav. We can determine the spatial composition of landscapes with forest vegetation, relief and water space. This allows you to allocate places for sight-seeing platforms. Small architectural forms must be in harmony with the surrounding landscape. Walking paths form the basis recreation areas. Turns and bends of routes for walking must comply with the elements of the landscape. Areas for recreation are usually located along the trail in of water bodies and in places of disclosure prospects. The recreation area is limited to with an enclosure which fits into the forest landscapes. In this case, the fence should not interfere with of migration of small animals (herpetofauna, insectivores, and others). The harmony of landscape elements serves as a criterion of completion of design. In the recreation area fire prevention measures have to be carried out by tenants. Permissible load of tourists to recreation areas is determined by a special technique. Conclusions: there was proposed a new kind of recreation facilities in the mountain forests - the zone for walking tourists. When carrying out forestry works, there will be a minimum of expenses on arrangement of the zone. Negative consequences to the forest environment would also be minimized
A training text in a foreign language is a fundamental communicative unit of the learning process. However there is tracing a tendency to explain the text as a global fact in the scientific literature and to study language’s contacts with different sides of human activity, which are actualizing through the text. The data shows at first that linguistic and cultural features of training texts are connected with communicative directivity of the foreign language learning process, second, they are due to the goals and objectives of learning. In the article the cultural component of training texts is reviewed, the types of texts determining sociolinguistic behavior of the characters, with which someone learning foreign language should identify himself, are marked, sociocultural subject of texts of tutorials in German and French is analyzed. A pragmatic aspect of training texts is studied separately, quantitative and genre texts’ relations and authentic and quasi-realistic texts’ relations in German and French are compared. Studying of features of training text in foreign language allows characterize it as a universal unit, which fosters to form a communicative competence and influence the recipient complex. Results of the study expand knowledge about the methodical potential of a training text in learning a foreign language and culture and are of interest for experts in the fields of linguistic, linguodidactics and intercultural communication
