In the world, the demand for quality and safe grain products is increasing. The need to preserve wheat in the event of a natural disaster requires the study of optimal storage times of grain without degrading technological indexes. The purpose of the work was to study the dynamics of technological properties of winter wheat grown after peas, clover, corn for silage and the industrial, ecological, biological growing systems during 1, 3, and 5 years of storage in the conditions of the ordinary granary. The absence of significant differences in the technological parameters of the grain of wheat grown at industrial and ecological systems, but significantly lower indicators at a biological growing system was found. The highest hectolitre weight obtained when wheat grain was grown after corn for silage, and vitreousness – after the clover. Significantly higher biochemical parameters of grain and alveographic properties of flour were for the cultivation of wheat after peas, which provided additional accumulation of protein substances. There are no significant changes in the indicator of hectolitre weight during the grain storage. Other indicators increased significantly after 1 year of storage (on average by 10 – 30%). For further storage, vitreousness growth was insignificant. After 5 years of storage, the falling number significantly increased (on 21% compared to the initial values and on 7% – after 3 years of storage). The content of protein, gluten in the grain, and alveographic properties of flour significantly decreased after 5 years of storage. The possibility of obtaining grain of wheat with high technological parameters for a more safe ecological growing system was established. It was also confirmed to need for grain storage up to 1 year to improve quality indicators and it was established that it safely stored for 3 years.

This article presents an analysis of the results of the study of flour obtained from batches of wheat grain at the stages of storage. It is shown that during the observed period of grain storage, the quality of the obtained wheat flour was stable and corresponded to the highest grade in terms of physicochemical parameters. Wheat of the 3rd class after 6 years of storage can be used for milling purposes for the production of bakery flour.

This report describes the features and the performance of a new and significantly improved 1536-well microplate design. The design allows for simple, automation-friendly, and cost-effective storage of compound solutions for high-throughput screening. The plate design is based on Society for Biomolecular Sciences standards for microplates and can be molded from polystyrene or cycloolefin copolymer, thus making the plate suitable for use with acoustic dispensing as well as other conventional liquid dispensing in the nanoliter range. For a 9:1 DMSO/water mix as solvent, the novel plate design has shown to perform over 4 months with only minor losses in solvent. Thus, this novel plate design creates the basis for further reductions in compound storage volumes and allows for an increase in the storage times for microliter volumes for up to a year or more. The high protection against solvent evaporation is also visible for aqueous solutions, thus allowing for reduced edge effects during screening campaigns.

AbstractWe investigated the effect of the following on the sterile integrity of surgical packs: four wrapping materials (two-ply reusable, nonbarrier wovens, both new and previously used; disposable, barrier nonwovens; and polypropylene peel pouches), dustcovers, two storage locations, and storage times ranging from 2 to 50 weeks. Two hundred sixty-three packs containing stainless steel coupons were prepared, wrapped, sterilized, and stored. Half of the packs were dustcovered prior to storage. At monthly intervals for a year, packs of each type were opened in a laminar flow hood, and the coupons inoculated into trypticase soy broth. The coupon contamination probabilities were 0.019 for reusable, woven packs; 0.017 for disposable, nonwoven packs; and 0.016 for peel pouches. These differences were not significant. The probability of finding a contaminated coupon in any pack after 50 weeks was 0.018. No trend toward increased probability of contamination over time was observed for any of the pack types studied.

The article shows the conditions for the development of microflora during long-term storage of grain. The results of studies of stored grain batches on microbiological indicators and mycotoxins are presented. It was found that the number of mesophilic aerobic and facultative anaerobic microorganisms and the number of mold fungi annually decreased by an order of magnitude when storing wheat in silos of elevators. During storage in silos of elevators, the concentration of mycotoxins in wheat did not change, and after a storage cycle of 3-4 years, the quantitative content of mycotoxins met the requirements of TR CU 015/2011 "On Grain Safety". After the storage, the wheat was safe from the point of view of toxic products of microbiological origin. This was facilitated by the low humidity of wheat (no more than 13%) and the optimal temperature regime: for most of the annual cycle, the grain was in a chilled state at a temperature below 10 °C.

For wheat grain with long-term storage, a set of additional methods has been developed that make it possible to assess its quality, firstly, as an object of long-term storage, and secondly, as an object for processing into flour and making bread from it after a storage cycle. Improving the methodology for assessing the quality of grain is a promising and relevant scientific direction in the development of the technological foundations for long-term storage of grain.

A study was conducted concerning effects of temperature and relative air humidity during long-term storage of wheat grain in a steel silo. The study was aimed at identifying the possibility of condensed moisture appearing under the silo roof. The probable periods of condensate in the space under the silo roof depending on the temperature difference inside and outside the silo have been determined. Some ways to prevent the condensate formation are proposed in the paper.

Several liquid lipids have been proposed to obtain nanostructured lipid carriers (NLC) with improved efficiency. An attractive strategy is the use of oils that could elicit a synergic effect with the loaded drug. In this work, different percentages (0–4% w/w) of tocopheryl acetate (TA), an oily antioxidant, were used as liquid lipid to prepare NLC loading idebenone (IDE), a synthetic antioxidant investigated for the treatment of neurodegenerative and topical diseases. The technological properties of such NLC were evaluated, as well as the interactions among lipid core components. Loading different percentages of IDE (1–4% w/w) into NLC containing TA up to 4% w/w, no significant change of mean size and polydispersity index was observed. IDE loading capacity was 4% w/w but NLC containing IDE percentages greater than 1.5% w/w showed poor stability during long-term storage. Differential scanning calorimetry analyses highlighted linear relationships between peak temperature and TA percentages, while the enthalpy variation and recrystallization index values showed that increasing the percentage of TA led to less crystalline structure of the NLC core. Therefore, NLC co-loading IDE and TA could be useful to design new delivery systems for the treatment of diseases that could benefit from the co-administration of these antioxidants.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
