SUPPLYING THE GREENHOUSES WITH POWER BY THE USE OF ASYNCHRONOUS GENERATORS
DescriptionDue to the recommendation of the World Health Organization, the standard rate of vegetables consumption for a person per year is 130-150 kg, including up to 15 kg of fresh production during the off-season. To meet these standards in Russia, the construction of greenhouses and greenhouse complexes was sped up. To cultivate the bulk of vegetables in the conditions of protected soil we have mostly used winter greenhouses. At the same time, in terms of the climatic conditions, the main production costs are accounted for energy carriers (up to 60 – 70%). The main consumers of energy in greenhouses are plants’ lighting and creation of the required temperature conditions for plants and soil. Annual increase of rates for energy carriers affects the cost of the greenhouses’ production. To increase the energy efficiency and independence in greenhouse complexes, it is proposed to use installations based on gas reciprocating units (GRU) for the production of two types of energy – electric and thermal. Such installations can run on the natural gas and other types of fuel. The drawback of existing installations is that they are mainly produced abroad or consist of the foreign components. As an alternative, we offer new technical solutions, which were developed and patented in the Russian Federation. What makes these solutions original is that asynchronous generators in the installations are used with various control schemes

Description
The transportation process plays an important role in the delivery of agricultural products to the consumer. On how well the fruits are preserved, their grade will depend, and, consequently, the price of them. It is known, that the annual damage from losses of agricultural products in the agro-industrial complex amounts to 8 billion rubles, according to various estimates. A large number of different factors affect the safety of fruits during transportation: temperature, humidity, smoothness of the vehicle, type of container, etc. The more factors will have a negative impact on fruit and vegetable products, the more losses will ultimately be. The appearance of dents and abrasions on the fruits gives rise to the formation of foci of rot, leading to damage to the transported products, and, as a consequence, reducing the grade. In order to reduce the losses of fruit and vegetable products in the process of transportation, the USSR and the Russian Federation have been and are working on the creation of containers and ways of transporting pomegranates. All of them, according to the authors, are able to reduce the dynamic loads that arise during the transportation process and have a negative impact on the transported products. However, due to various circumstances in commercial gardening all these developments have not been extended

Description
The competitiveness of any company engaged in the wholesale or retail sale of goods and services is substantially determined by the level of quality of the services provided. For the accompanying business of vertically integrated oil companies, the criterion of quality service is not an exception. Currently, cafes and shops at the refueling complex are not only a convenient service for customers, but also a solid source of additional revenues for the largest oil companies, each of which seeks to make the retail network attractive to customers by offering a wide range of goods in stores, ready meals in a cafe, and related services. To satisfy the needs of the client, it is necessary to offer a wide, but rational assortment of goods at the refueling complexes. The claimed goods must always be at the refueling complexes. The lack of goods necessary for the customer on the shelf means the loss of sales and profits, the order and location of goods that are not in demand - the formation of surpluses, returns to the supplier and write-offs. This also affects the overall economic performance of the company. In this regard, the increase of logistics service is one of the priority tasks of the accompanying business of vertically integrated oil companies
