Study of changes in the technological performance of raw cotton when storing

The results of the experiments showed that with an increased density of raw cotton that occurs in the lower layers of the bundle and an increase in its shelf life, an increase in the mass fraction of defects and trash in the fibre is observed. It was found that with an increase in the density of raw cotton more than 250 kg/m3, the mass fraction of defects and weeds in the fibre increases by almost 10 %, the damage to seeds by 6 %, the staple mass length decreases by 3 %, and the proportion of short fibres by 9 %. The increase in the shelf life of the fibre also negatively affects the quality of the fibre and seeds and, most importantly, cotton for grades III–V. An increase in the mass fraction of flaws and trash in the fibre, in turn, affects the unevenness of the yarn and the quality category of the resulting yarn.

QUALITY MANAGEMENT OF LUMBER DRYING IN CONVECTIVE AUTOMATIC CHAMBERS

The timber industry complex of Russia has no less potential than the recognized flagships of the Russian industry – the oil and gas sector, the metallurgical and military-industrial complex. The potentialities of the Russian woodworking industry and such a traditional industry as sawmilling are especially great. According to available forecasts, despite significant growth in the production of panel materials, cardboard and paper, the demand for sawnwood will increase, especially in Europe. The recommendations for improving sawmill production emphasize the need to increase the volume of sawn timber drying, expand the range of products by producing targeted dry sawn timber, and bring the requirements for the quality of sawn timber drying to consumer requirements. Specific issues related to quality management of woodworking products have basically been resolved. At the same time, there are a number of bottlenecks in the management of drying quality that cannot be solved at once. This is especially true for issues related to the significant instability of the properties of wood subjected to drying. The system of controlled moisture exchange proposed by the authors makes it possible to largely neutralize the influence of the scatter of the initial properties of wood on the entire drying process. This applies to both the moisture removal process itself and the development of internal stresses in the wood with the provision of the required margin in order to avoid wood cracking. Moreover, the controlled moisture exchange system allows the formation of a drying regime in accordance with the required quality category with minimal energy consumption for drying.

Limnochemistry and Plankton Diversity in Some High Altitude Lakes of Kashmir Himalaya

High altitude lakes (HALs) of Kashmir Himalaya are the important ecosystems in the mountain ecology of the broader Hindukush Himalayan region. This article provides a comprehensive information about the plankton (phytoplankton and periphyton) assemblages, water quality (WQ), bathymetry, morphometry, and land use land cover (LULC) of some select high altitude mountain lakes of Kashmir Himalaya. LULC analysis revealed that the catchment of the lakes spread over an area of about 16179 ha, is covered by different land cover types dominated by pastures (50.8%), followed by barren rocky (32.6%), snow and glaciers (11.9%), lakes (2.5%), forest (2%), and streams (0.2%). Bathymetric and morphometric analysis revealed that the Gangbal Lake is the deepest (84 m) and largest (162.4 ha) among the investigated lakes. The water quality index revealed that all the HALs have the excellent water quality category. Statistical analysis (Wilk’s λ) depicted that nitrate-nitrogen (NO3−-N), nitrite nitrogen (NO2−-N), ammoniacal nitrogen (NH3-N), total phosphorus (TP), and magnesium hardness (Mg-H) are responsible for major variability between all HALs sites. The cations followed the order of Ca2+ > Mg2+ > Na+ > K+ while as anions followed the order as HCO3− > Cl− > SO42−. Algal composition (phytoplankton and periphyton) assessment revealed the presence of 61 taxa belonging to Bacillariophyceae (45), Chlorophyceae (14), Cyanophyceae (1), and Xanthophyceae (1). The higher dominance of Bacillariophyceae indicates oligotrophic nature of the lakes. Canonical correspondence analysis (CCA) highlighted the role of various water quality parameters like pH, EC, and TDS on the composition of phytoplankton and periphyton species among the lakes. The present study therefore generated a baseline database for some of the HALs of Kashmir Himalaya that can act as a precursor for more research on future changes in the lake ecosystems of the region.

Classification Maps for TDS Concentrations in the GIS Along Euphrates River, Iraq

Iraq currently undergoing the problem of water shortage, although Iraq has two Rivers (Euphrates and Tigris) pass throughout most of its areas, and they have represented a major source of water supply. In the current research, to evaluate the quality of the Euphrates river in Iraq based on the values of total dissolved salts (TDS), the TDS concentrations were collected from sixteen sections along the river in the three succeeding years (2011, 2012, and 2013). The evaluation of the river was done depending on the classification of (W.H.O. (World Health Organization). (2003). Total Dissolved Salts in Drinking-water: Background document for development of W.H.O. Guidelines for Drinking-water Quality. World Health Organization, 20 Avenue Appia, 1211 Geneva 27, Switzerland). of rivers for drinking uses. Inverse Distance Weighting Technique (IDWT) as a tool in the GIS was employed to establish the maps of the river that using interpolation/prediction for the TDS concentrations to each selected year and the average values of TDS for these 3 years. Based on the five categories of rivers’ classification of the TDS concentrations according to the (W.H.O. (World Health Organization). (2003). Total Dissolved Salts in Drinking-water: Background document for development of W.H.O. Guidelines for Drinking-water Quality. World Health Organization, 20 Avenue Appia, 1211 Geneva 27, Switzerland), the Euphrates river was classified, and the maps of classification for the years 2011, 2012 and 2013 and the average values for 3 years were created. The average values for 3 years of TDS along the Euphrates river indicated that the sections from SC-1 to SC-4 as moderate-water-quality-Category-3, the sections from SC-5 to SC-10 as poor-water-quality-Category-4, while the sections between SC-11 to SC-16 as very poor-water-quality-Category-5. The interpolation maps showed that the Euphrates river in Iraq was ranged from moderate water quality (Category-3) to very poor water quality (Category-5).

Linear combination of chi-squares for multinomial process monitoring

Marcucci (1985) proposed a chi square goodness of fit statistic based generalized p-chart for multinomial process monitoring. A chi square distribution quantile was considered as a control chart limit. A weighted chi square goodness of fit statistic-based control chart is proposed for multinomial process monitoring in this paper, where more important weights are advocated to poor quality categories. The statistic distribution is approximated by a well-known linear combination of chi squares distribution. The approximation is assessed through a simulation, an extreme percentile of the approximated distribution is used as an upper control chart limit and a comparison is carried out with a chi square goodness of fit statistic-based control chart. The average run length is used as a benchmark and the comparison is performed using simulations considering two process shifts scenarios. Under some restrictions, the weighted statistic-based control chart allows an earlier detection of process shift in case of deterioration and postpones out of control signals in case of improvement. This benefit is clearer when the process is improved by a decrease in the poor quality probability category and an increase in the best quality category probability.

The effectiveness of the use of microbiological preparations when interacting with seed stocks of the genus Prunus L.

An important element of increasing the efficiency of production of high-quality planting material of fruit crops according to the criteria of environmental management, resource conservation and productivity is the use of adaptive, technological rootstocks, as well as microbiological preparations that are environmentally friendly and multifunctional. They stimulate plant growth by changing their hormonal status, act as fungicides, as bio protectors, forcing the plant turn into its defense mechanisms, as bio fertilizers that promote the absorption of atmospheric nitrogen by plants, hard-to-reach forms of phosphorus, a number of trace elements, have an anti-stress effect, etc. To control the process of obtaining seedlings of the highest quality category, it is necessary to study the living system “plant-microbiological preparation-environment”. As a result of this research, it was found that the high temperature background in combination with severe drought, observed during the years of research, adversely affected both the development of rootstocks in the first field of the nursery, and the effect of microbiological preparations. When developing resource-saving elements in technology - the selection of genotypes and microbiological preparations for growing rootstocks, bypassing the school of seedlings, form 3-106 was highlighted, when using the preparation Pseudobacterin-2. Found a regularity - a positive interaction in the conditions of the Ust-Labinsk district of OLL “Experimental Nursery (EN) named after K.A. Timiryazev” seedlings of rootstocks for sweet cherry and cherry, of different origin, and the preparation Pseudobacterin-2. In conditions of high temperatures in the spring-summer period, the isolated preparation increased the germination capacity and the yield of high-quality planting material.

Existential Necessity for Dominance of the “Quality” Category in Socio-economic Development of the Russian Federation as Part of the Global Anthropogenic World

The evolution of man-made technological society to the scale of the global system has changed the whole nature of social reproduction. The modern global biosocium “rests” on the quasi-closure of the main subsystems of our planet — the biosphere and planetary matter, their quantitative limitations. It is impossible to remove (resolve) this contradiction under the dominance of the category “quantity”, in the conditions of the promoted flywheel of the consumption society. The aggregate “amount” of public reproduction already crosses the boundary of the category “measure”. Therefore, the development of the global technological biosocium (noosphere), its relationship with the biological and basic planetary subsystems enters the zone of existential bifurcation, in which the likelihood of the appearance of the effect of a “butterfly” capable of destroying all humanity increases sharply. The authors justify the acute existential need for the priority of the “quality” paradigm in the social reproduction of the Russian Federation by its special position in the global world, the bifurcation state of the entire anthropogenic technological civilization and the socio-biological nature of man
