INFLUENCE OF MACROSTRUCTURE ON THE DENSITY OF OAK WOOD

An individual process of staining of each trunk occurs as a result of the long-term presence of wood in the river soil without oxygen access. It consists in changing the structure and chemical composition of the wood. There are industrial reserves of this wood on the territory of the Russian Federation, in the floodplains of a number of rivers. One of the most important tasks at the extraction stage is the primary individual quality assessment of the trunk. One of the most effective diagnostic indicators for assessing wood quality can be the number of annual layers in one centimeter. This indicator correlates well with wood density. The purpose of the research is to establish the influence of the macrostructure of natural wood and stained oak wood, changes in the microstructure on its density. It was found that the density of stained oak wood, depending on the number of annual layers in 1 cm, is about 10% higher than that of natural wood, all other things being equal. The magnitude and nature of the decrease in density along the radius of the trunk is the same as in natural wood. It is about 20%. The performed studies will allow making an express analysis of the quality of each stained wood trunk at the stage of making a decision on the behavior of its extraction. This will significantly reduce the cost of logging and primary processing of stained oak wood

The paper presents the results of long-term research on the infl uence of pinching of Northern ecotype soybeans (Okskaya variety) on yield, protein, and oil productivity in high latitudes (57°), a long day, a limited amount of active temperatures (1700…2000 °C) on sod – podzolic soils of the Non-Chernozem zone of the Russian Federation. The authors determine the prospects of using the method for varieties of an indeterminate type of growth. The pinching of crops was carried out three times: at the beginning of the fl owering phase, in the middle of the fl owering phase, and at the beginning of the bean formation phase. It was found that the pinching of crops carried out at the beginning of the bean formation phase, reduces the duration of the growing season by an average of 15 days. The technique ensures a more than double increase in the number of side shoots. The share of the coarse fraction of seeds was about 89%, the yield of seeds reached up to 2.00 t/ha, the protein content in seeds – up to 42.2%, fat – up to 19.1%, protein collection from the seed yield – up to 0.834 t/ha, essential amino acids in protein – up to 0.459 t/ha, fat – up to 0.380 t/ha, collection of unsaturated fatty acids – up to 0.228 t/ha. It is shown that the technique allows optimizing the ripening processes without reducing the productivity and quality of the crop, while the costs of pinching are paid off by reducing the costs of harvesting. The obtained data can be used to optimize soybean growing technologies at the northern border of the soy cultivation

Radio Planning

Transitioning a Terrestrial Trunked Radio (TETRA) network to a Long-Term Evolution (LTE) network in public protection and disaster relief (PPDR) systems is a path to providing future services requiring high radio interface throughput and allowing broadband PPDR (BB-PPDR) radio communications. Users of TETRA networks are currently considering how to deploy a BB-PPDR network in the coming years. This study offers several radio planning considerations in TETRA to LTE migration for such networks. The conclusions are obtained from a case study in which both measurements and radioelectric coverage simulations were carried out for the real scenario of the Murcia Region, Spain, for both TETRA and LTE systems. The proposed considerations can help PPDR agencies efficiently estimate the cost of converting a TETRA network to an LTE network. Uniquely in this study, the total area is divided into geographical areas of interest that are defined as administrative divisions (region, municipal areas, etc.). The analysis was carried out using a radio planning tool based on a geographic information system and the measurements have been used to tune the propagation models. According to the real scenario considered, the number of sites needed in the LTE network—for a specific quality of service (90% for the whole region and 85% for municipal areas)—is a factor of 2.4 higher than for TETRA network.

The objective of this study was to assess the risk of bacteremia, estimate the cost and evaluate the quality of life by using a transparent dressing (TD) versus (vs) a dry gauze (DG) on the exit site of long term central I.V. catheters (LTCC) of hemodialysis patients. This 6-months preliminary study was conducted on 58 patients (pts) randomized to receive DG replaced 3 times/week (29 pts) or TD replaced every 7 days (29 pts). Data on patients, conditions of the exit site, local infection, bacteremia, quality of life and cost related to each type of dressing were collected. Two pts in the DG group experienced bacteremia related to their LTCC vs 1 pt in the group TD. A total of 7 (DG) vs 13 (TD) pts experienced skin condition changes at the catheter exit site. Some skin reactions, erythema and pruritus, did occur initially in the group TD and was due in part to insufficient drying time of the skin preparation solution. The estimated individual, weekly costs for using the DG was $7.60 vs $4.72 Canadian dollars for the TD. The SF-36™ scores did not show a significant difference between the 2 groups during the study (3.8 (PCS), 6.4 (MCS) at study end). Although this study was statistically underpowered, it suggests that the incidence of bacteremia was not increased with the use of a TD. Moreover, the use of a TD allowed fewer dressing changes, lowered total treatment costs, with no observed unfavorable impact on the quality of life and without significant local complications of the exit site. Based on the positive results observed in this pilot study, further study is warranted to examine the cost effectiveness of long-term use of TD dressings on dialysis catheter exit sites.

Museum Practice

<p>In the current economic climate museums are increasingly being asked to do more with less. For museums that hold collections, this poses a unique challenge. With the cost of collections being relentlessly accumulative, questions are being raised about the long term financial sustainability of current collecting practices. Deaccessioning is being suggested as a way in which museums can improve the quality of their collection without increasing its size. Yet the literature on deaccessioning suggests that the process is fraught with ethical and practical difficulties. By highlighting the negatives aspects of the process, writing in museum studies and practice does little to explore how deaccessioning might be used to achieve positive outcomes. This research addresses this gap by asking whether deaccessioning is a positive tool that, if used appropriately, can assist a museum in improving the quality and manageability of their collection through systematic planning. To understand how and why a museum may permanently remove objects from their collection, the study focuses on one New Zealand museum’s response to the challenge of redeveloping a collection through the process of deaccessioning and disposal. The Museum of Wellington City and Sea’s deaccessioning process is analysed through documentary research and interviews with Museum staff. The interviews offer an understanding of the thought processes and motivations involved in selecting objects to be deaccessioned. The data collected reveals both the challenging aspects of the process but also offers insights into how these aspects can be mitigated or resolved. The conclusions presented in this dissertation suggest that deaccessioning is an integral part of current museum practice that can be used positively to actively shape and refine a museum collection. I argue that some of the beneficial outcomes of the process include greater understanding of collections, improved knowledge and context, resolution of historical collecting problems, strategic relationships built with other museums and improvement in how objects are stored and utilised. More importantly deaccessioning allows museums to determine the character and content of their collections. In order for this to be achieved, I recommend that museums adopt a rational approach to reviewing their collections that is multi-disciplinary, transparent and acknowledges how their collection is used in the achievement of their institution’s mission.</p>

The goal- at present there is no clear concept for the long-term development of infrastructure of agro-industrial complex in the republic, and the degree of support for agricultural sector is inferior to the level of advanced countries, which may lead to a restriction of the population's access to quality food. Methods - abstract-logical, monographic, sociological survey, economic-statistical, analytical. Results - the best world practice of rural entrepreneurship was reviewed. The experience of farmers of the Russian Federation, economically developed countries of the EU, Eastern Europe, advanced Asian States, including Japan and South Korea, is presented. It is indicated that the main condition for preservation and multiplication of the achievements of the AIC of the Republic of Kazakhstan is the socio-economic growth of rural settlements. The authors focus on the issue of ensuring food security - one of the main tasks of the economy of each country, the key areas of implementation of which are public support for agricultural sector, improving the quality of life of rural residents. The activity of agricultural producersis analyzed, problems of development of agribusiness in these countries and Kazakhstan are reflected, recommendations for their solution are presented. Conclusions - the following basic factors contributing to the formation and expansion of entrepreneurship in agro-industrial production are highlighted: improvement of the regulatory and investment base; business management, which implies transformation of the structure and advanced training of specialists of enterprises of agro-industrial complex, as well as the heads of peasant (private) farms. Access to markets is a serious problem for small and medium-sized enterprises in agricultural sector, which has a significant impact on the sphere of agricultural production and processing of agricultural products. The research results can be used in the development of measures to support SMEs in agricultural sector at the regional level.

Community Centre

This case study aims at comprehensively assessing a decision by XYZ Ltd (name withheld due to confidentiality), New Delhi, on whether to build or to lease a recreation centre for its rank-and-file employees. Based on a cost–benefit analysis, we concluded that the centre should be built since the company would recover its investment within 11 years. Apart from the financial considerations, the recreation centre could be considered a long-term investment in employee morale, as it would lead to a better quality of life for the staff and their families, and is likely to enhance their sense of belonging and improve productivity. To date, what little space there is available for hosting family functions is reserved for the use of the officers, and only officers and their families are invited to most company functions. Thus, the other employees feel neglected by the management. Hiring a community centre external to the organisation for a function would involve spending a lot of money as the company is located in a prime real estate area where the cost of land and rentals is huge, and sometimes even availability is an issue. Most of the staff cannot afford such places and are generally under a lot of stress whenever they have a family function. This, in turn, tends to affect their productivity.

Growing global population has caused environment degradation through ecosystem impairment and over exploitation. Although, people have made great moves for improving life style, and enjoy a drastically improved quality of life but such improvements have been made at the cost of environment degradation. Climate change will force humans to adjust with changing environment and find ways to deal with short term protection and long term health consequences. The range of potential threats to human health caused by climate change is increasing and at the same time is not clear. So, owing to the potential magnitude and universality of such an issue, we have a moral obligation for developing proper tools and make informed choices that ultimately result in better lives for the humans.
