A by-product of soybean production, as a non-grain part of the crop, can be used to meet the needs of livestock in providing complete feeding of livestock. Pressing the floor allows to reduce the volume of plant material in order to reduce the cost of storage and transportation, improve the safety of its nutrients during long-term storage. Therefore, the development of an efficient, cost-effective and less energy-intensive technology and a process line for compacting the soybean floor by pressing is a promising direction. The pile of the floor is a complex mixture of particles of different sizes, as well as voids filled with air. Equipment compaction chaff should provide a stable preparation of pellets under all the fluctuations of the moisture content and fractional composition of chaff. In 2018, research experiments were carried out in the Far Eastern Scientific–Research Institute of Mechanization and Electrification of Agriculture to study the process of pressing the soybean floor, depending on its fractional composition and humidity, on the manufactured laboratory unit for compaction with the production of soybean floor briquettes. It was found that when the humidity of the sample increases from 9 to 21%, the energy consumption decreases by 17.1%. The coefficient of compaction of the floor when the humidity changes almost does not change. By increasing the length of the sex particles from 14 to 87 mm, the compaction coefficient increases by 73.3% and the energy intensity by 6.2 %. For transportation and storage of the soybean floor briquette, it is recommended to pack it tightly with polyethylene film or tie it with twine, this will increase the shelf life and eliminate losses.

The introduction and active use of information transmission and storage systems in the Ministry of Defense (MoD) of Ukraine form the need to develop ways of guaranteed removal of data from media after their use or long-term storage. Such a task is an essential component of the functioning of any information security system. The article analyzes the problems of guaranteed destruction of information on magnetic media. An overview of approaches to the guaranteed destruction of information on magnetic media of different types is presented, and partial estimates of the effectiveness of their application are given by some generally accepted indicators of performance evaluation. The article also describes the classification of methods of destruction of information depending on the influence on its medium. The results of the analysis revealed the main problems of application of software methods and methods of demagnetization of the information carrier. The issue of guaranteed destruction of information from modern SSD devices, which are actively used in the formation of new systems of information accumulation and processing, became particularly relevant in the article. In today's conditions of development of the Armed Forces of Ukraine, methods of mechanical and thermal destruction are more commonly used today. In the medium term, the vector of the use of information elimination methods will change towards the methods of physical impact by the pulsed magnetic field and the software methods that allow to store the information storage device, but this today requires specialists to develop new ways of protecting information in order to avoid its leakage.

The problem of utilization or recycling industrial tobacco wastes is an important problem for tobacco industry. Economically preferable way for utilizing industrial tobacco wastes (tobacco scrap) is production smokeless products and hookah blends as wastes are utilized without special treatment. Monitoring of humidity and fractional composition of cut tobacco taken from tobacco rod/cigarette spoilage (tobacco scrap) is carried. Its long-term storage leads to increasing scrap and dust quantity. Researches on utilizing tobacco scrap for sniff and hookah blend production, which are considered to be less harmful compared to cigarettes, were carried. Chemical composition of American type tobacco and scrap was defined. Nicotine content varies from 0.9 to 2.4% and carbohydrates content – from 5.6 to 9.6%. Experimental samples of hookah blend were produced and their organoleptic and taste evaluation were carried. It was found that utilization of tobacco scrap is economically efficient for hookah blend production, as quality of final product made of leaf tobacco and tobacco scrap is similar. Experimental samples of sniff tobacco were produced in order to discover possibility of utilization industrial tobacco scrap for manufacturing this product. Consumer’s properties of sniff tobacco were evaluated by 100 points tasting protocol. This technology for sniff tobacco production from tobacco scrap allows manufacturing product of good quality, decreasing technological operations, rejecting stages of tobacco selection and its cutting and as the result decreasing cost of final product. The results of the research on utilizing tobacco scrap for hookah blend and sniff tobacco production proves optimality of recycling the tobacco wastes.

ABSTRACT Parasitic Chytridiomycota (chytrids) are ecologically significant in various aquatic ecosystems, notably through their roles in controlling bloom-forming phytoplankton populations and in facilitating the transfer of nutrients from inedible algae to higher trophic levels. The diversity and study of these obligate parasites, while critical to understand the interactions between pathogens and their hosts in the environment, have been hindered by challenges inherent to their isolation and stable long-term maintenance under laboratory conditions. Here, we isolated an obligate chytrid parasite (CCAP 4086/1) on the freshwater bloom-forming diatom Asterionella formosa and characterized its infectious cycle under controlled conditions. Phylogenetic analyses based on 18S, 5.8S, and 28S ribosomal DNAs (rDNAs) revealed that this strain belongs to the recently described clade SW-I within the Lobulomycetales. All morphological features observed agree with the description of the known Asterionella parasite Zygorhizidium affluens Canter. We thus provide a phylogenetic placement for this chytrid and present a robust and simple assay that assesses both the infection success and the viability of the host. We also validate a cryopreservation method for stable and cost-effective long-term storage and demonstrate its recovery after thawing. All the above-mentioned tools establish a new gold standard for the isolation and long-term preservation of parasitic aquatic chytrids, thus opening new perspectives to investigate the diversity of these organisms and their physiology in a controlled laboratory environment. IMPORTANCE Despite their ecological relevance, parasitic aquatic chytrids are understudied, especially due to the challenges associated with their isolation and maintenance in culture. Here we isolated and established a culture of a chytrid parasite infecting the bloom-forming freshwater diatom Asterionella formosa. The chytrid morphology suggests that it corresponds to the Asterionella parasite known as Zygorhizidium affluens. The phylogenetic reconstruction in the present study supports the hypothesis that our Z. affluens isolate belongs to the order Lobulomycetales and clusters within the novel clade SW-I. We also validate a cryopreservation method for stable and cost-effective long-term storage of parasitic chytrids of phytoplankton. The establishment of a monoclonal pathosystem in culture and its successful cryopreservation opens the way to further investigate this ecologically relevant parasitic interaction.

In three-year field experiments, the effect of genotype, flesh color, site conditions and storage on chlorogenic acid content (CAC) in tubers of potato cultivars with purple or red flesh was compared to yellow-fleshed cv. Agria. The results confirmed the significant effect of genotype on CAC. The highest CAC was characteristic on a three-year mean for the purple-fleshed cv. Vitelotte (769.5 mg/kg fresh weight (FW)), i.e. 1.19−2.6 times higher than in the other cultivars. In regard to the effect of flesh color, significantly higher mean CAC levels have been shown for the red-fleshed (2.8 times) and purple-fleshed (3.16 times) cultivars in comparison with cv. Agria (148 mg/kg FW). At the Uhříněves location with a warmer climate and frequent dry periods as compared to the second Valečov location, a higher CAC (1.18 times) was found. Cold storage (4°C, 6 months) resulted in a significant CAC increase varying from 33.2% in the Blaue St. Galler cultivar to 210.6% in the Vitelotte cultivar among all eight evaluated color-fleshed cultivars. On the other hand, the effect of storage on CAC was not evident in the yellow-fleshed Agria cultivar (inconclusive difference against CAC after harvest).

The work objective is to substantiate the technical bases for the production of gas hydrate blocks directly on-site for further transportation and storage in above ground storages, as an alternative to transporting and storing gas in underground gas storages. The theoretical bases have been considered and processes of gas hydrate blocks producing, physical-mechanical characteristics of artificial hydrates with the purpose of determining the conditions of their storage and prolonged storage were tested in laboratory conditions. The construction of above ground gas hydrate storage in the form of a building, partially deepened in a ground, which is separated from the environment by a wall of gravel cement elements made by the mixing method were substantiated. It is proved that such a constructive solution for a long-term storage of gas hydrate blocks is the most economical in terms of energy consumption to maintain internal negative temperature.

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.

Cereal and pasture hays, cut at the same site, were packaged into medium-sized round bales, large round bales and stacks. Halfthe number of each hay type and of each hay package were stored in the open for up to 15 months in a 500 mm rainfall area and half were transported to and stored for up to 15 months in a 1000 mm rainfall area. Densities of the pasture hay packages were within the manufacturers' specified ranges but those of the cereal hay packages were lower. Medium-sized round bales were less dense than large round bales and weathered more than large round bales and stacks after 10 and 15 months storage. Cereal hay packages deteriorated more than pasture hay packages with long-term storage. Medium-sized round bales lost more dry matter than large round bales after storage over the winter and more digestible dry matter over this period and after long-term storage. They also lost more crude protein than large round bales when stored over the first summer and over the following winter. It was economic to store all packages in the open over the first summer. It was uneconomic to store medium-sized round bales in the open over the following winter, while storage of large round bales and stacks was economic. For long-term storage, it was uneconomic to store any of the hay packages in the open, and storage under cover would have to be considered.

This study aimed to evaluate apple firmness measured using both the penetrometer and acoustic methods. The methodologies were applied to Royal Gaya and Golden Smoothee apples (Malus domestica. Borkh) harvested from 12 different orchards in Catalonia (Spain), on six different dates, and over three seasons. The relationship between firmness and physicochemical quality parameters was analyzed at harvest and post-harvest. The results obtained showed a noticeable correlation between Magness Taylor firmness and acoustic measurements in Royal Gala, but no correlation was found for Golden Smoothee. Fruit variety and storage had a clear influence on correlations between the two measurements. Measurements of Magnes Taylor and acoustic firmness seemed to correspond to different physical properties. Acoustic measurements seemed to be a good tool for evaluating changes in tissue firmness during long-term storage, especially for Golden Smoothee apples. The maturity of the fruit seemed to play a more important role in the measurement of Magnes Taylor firmness than in the measurement of acoustic firmness for the Royal Gaya variety.

An automated system for mounting and dismounting pre-frozen crystals has been implemented at the Stanford Synchrotron Radiation Laboratory (SSRL). It is based on a small industrial robot and compact cylindrical cassettes, each holding up to 96 crystals mounted on Hampton Research sample pins. For easy shipping and storage, the cassette fits inside several popular dry-shippers and long-term storage Dewars. A dispensing Dewar holds up to three cassettes in liquid nitrogen adjacent to the beamline goniometer. The robot uses a permanent magnet tool to extract samples from, and insert samples into a cassette, and a cryo-tong tool to transfer them to and from the beamline goniometer. The system is simple, with few moving parts, reliable in operation and convenient to use.
