Current state and potential of Forage Production in the Non-Chernozem region

В Доктрине продовольственной безопасности России на период до 2030 года одной из приоритетных задач является повышение обеспеченности народонаселения молочно-мясной продукцией отечественного производства. Для успешного решения этой задачи потребуется интенсификация кормопроизводства не только на мегафермах, но и на традиционных сельхозпредприятиях, в крестьянских фермерских и личных подсобных хозяйствах. В статье на примере Нечернозёмной зоны дана оценка современного состояния кормопроизводства и перспектив его развития до 2030 года с использованием статистических данных, научно обоснованных рекомендуемых технологий и систем повышения продуктивности кормовой базы на основе сочетания полевого и лугового кормопроизводства, а также с учётом предложений, сформулированных ведущими учёными-экономистами по модернизации управления аграрными и нерегулируемыми рыночными отношениями. На основе анализа современного состояния полевого и лугового кормопроизводства и имеющегося научно-производственного опыта дано обоснование многовариантным направлениям модернизации этой отрасли сельского хозяйства для решения задач, поставленных в Доктрине по развитию животноводства. Соотношение полевого и лугового кормопроизводства в каждом регионе и даже каждом хозяйстве зависит не только от природно-экономических условий и современного состояния сельскохозяйственных угодий, но и от экономических показателей технологий их интенсификации, себестоимости корма и животноводческой продукции, её количества, а также здоровья и продуктивного долголетия животных. Для достижения цели, поставленной в Доктрине, необходимо научным сообществом и макроэкономическим руководством разработать критерии выполнения программы, экономические стимулы её поддержки и методологию, которая послужит основой для разработки программы по федеральным округам и областям, а также основой методики для различных типов хозяйств. According to the Food Security Doctrine of the Russian Federation one of the priority tasks is the increase in domestic milk and meat products by 2030. To achieve this goal advanced forage production technology is required. This paper reports on the current state of the forage production sphere in the Non-Chernozem region as well as potential approaches to improve it by 2030. The review deals with statistical data, validated technologies and methods combining field and grassland forage production, expert evaluation of agricultural and free market relations. Promising ways to improve this sphere are based on theoretical and practical investigations of the current state of field and grassland forage production. Proportions of field and grassland forage in the particular region depend on environmental conditions, economy, quality of agricultural lands, economic efficiency of a modernization approach, prime costs of feed and animal products as well as health and productivity of livestock. To meet the Doctrine goal researchers and leading economists have to introduce criteria to implement modernization, provide financial support and methodology as a basis of such modernization suitable for particular regions and farms.

Directions of Artillery Development on the Example of the US Military and Artillery Use in the Baltic Sea Region

This article discusses role of field artillery on battlefield and the current state of field artillery. The purpose of this article is to outline development directions of artillery capability. Army surface-to-surface indirect fires will have a crucial part on the future battlefield. Essential trends in field artillery include: increase in range of fires systems; develop and disseminate of multi-sensor active-seeker munitions; advancement automated command and control; develop and implementation systems order to protect ground forces and forward operating bases from the threat of rockets, artillery, and mortars (C-RAM).

Land management under protective forest plantations at the local level: decentralization models

The state of field protective afforestation in Ukraine has been studied and it has been found that the indifferent attitude of the state to field protective forest belts for many years has led to a ecological crisis (we have about 15 million hectares of degraded soils and estimated losses of 33-35 billion hryvnia annually), which is also the result of the long absence of the owner of these lands. Characterizing the problems associated with the use of forest plantations in terms of the interests of management and economic entities, it was found that currently the most influential entities are the state, the State Forestry Agency, united territorial communities and people whose interests compete with each other. Based on studies of the evolution of land ownership under protective forest belts, taking into account the decentralization processes taking place in the country and taking into account the provisions of the Laws of Ukraine, models of their management at the local level are proposed. Emphasis is placed on the fact that, regardless of the choice of the owner, preference is given to the creation of a municipal agroforestry reclamation enterprise for the arrangement of protective forest belts.

Centrally Decentralising? Analysing Key Policies and Pathways in Norway’s Electricity Transitions

With national electricity systems, ‘transition’ may involve decentralising production and ownership, and digitalising the system. These processes are facilitated by smart metering, ‘prosuming,’ and changes in consumer behaviour. Driving factors may be national steering, or the process can be left to the market. In Norway, the government has opted for tightly steered national coordination of three key areas: national smart-meter implementation (since 2011), prosumer regulation (since 2016), and a national end-user demand flexibility regulation (expected to be adopted in 2020). These regulations influence production patterns, energy flows and grid activities. Drawing on organisational fields theory, this article asks: Why was it decided to adopt these policies centrally? Which actors have had greatest influence on policy outputs? And, finally, what of the possible implications? The regulations, developed in a sector in a state of field crisis, have generally been supported by the relevant actors. The Norwegian case can help to explain incumbent roles and field crisis, as well as nuanced drivers in complex transitions, beyond decarbonisation.

Bound state in a model of electromagnetic field interacting with a material plan

In the model with Chern-Simons potential describing the coupling of electromagnetic field with a two-dimensional material, the possibility of the appearance of bound field states, vanishing at sufficiently large distances from interacting with its macro-objects, is considered. As an example of such two-dimensional material object we consider a homogeneous isotropic plane. Its interaction with electromagnetic field is described by a modified Maxwell equation with singular potential. The analysis of their solution shows that the bound state of field cannot arise without external charges and currents. In the model with currents and charges the Chern-Simons potential in the modified Maxwell equations creates bound state in the form of the electromagnetic wave propagating along the material plane with exponentially decreasing amplitude in the orthogonal to its direction.

ANALYSIS OF THE TRACER STUDIES RESULTS: A STUDY OF AS1-3 FORMATION OF THE SEVERO-OREKHOVSKOYE OIL FIELD

In oil field practice tracer (indicator) studies are an effective and efficient method of monitoring the state of field development. Using the multifactor mathematical analysis, the nature and intensity of the impact of injection wells on production wells have been compared with the results of injection of indicator liquids. Injection of indicator liquids was carried out along the AS1-3 formation at the Severo-Orekhovskoye oil field through the wellheads of the injection wells. The technique provides for correlation of injection in all potentially possible directions within a given range of action (usually no more than 2 rows), excluding one or more of the wells and more from the analysis. There is a direct positive correlation between evaluation data on indicator downloads and multivariate mathematical analysis data. The convergence of the results is 65%.
