In this paper the essential elements concerning cattle and swine rearing and growing conditions were given in order to establish welfare and biosecurity standards. These elements were formed according to detailed annual investigations on 11 cattle and 5 swine farms and include relevant spatial, microclimate and hygienic conditions. In order to establish welfare standards, certain spatial conditions have higher importance, such as correct construction and maintenance of beds, pens and yards, and type and quality of materials used to build beds and walls. It is necessary to enable movement of animals in stables and yards as basic physiological and ethologic needs, according to latest scientific data. Also, optimal temperature, relative humidity and air velocity insuring have to be considered, as well as quality ventilation in order to establish and preserve optimal microclimate conditions. Also, it must be pointed out that hygiene maintenance of stable surfaces and animal bodies on a regular bases is essential. Basic principles and criteria for welfare level assessment are given in this paper. According to results obtained in previous investigations, special attention is given to possibilities to correct rearing and growing conditions in cattle and swine farms in our country. .

The demand for dental orthopedic assistance in Russia makes more than 60% of the number of examined patients. With this, a share of use of removable dentures for rehabilitation of patients with partial or complete absence of teeth makes 40.2% of all types of prosthetics. Removable prosthetics remains an actual treatment option for patients with partial or complete absence of dentitions, along with use of non-removable structures including those with support on dental implants. Improvement of approaches to manufacture and design of dentures led to a considerable increase in the variants of combinations of materials and methods of their manufacture, and there appeared a possibility to optimize denture structures due to the ability to compensate for atrophic processes of the bone tissue. All this permits an orthopedist to achieve satisfactory results in treatment with use of removable dentures. In the given literature review, modern views on the variants of orthopedic rehabilitation of patients with use of removable laminar dentures are presented including their technological, functional, operational, phonetic, chewing peculiarities, and information on modern materials for manufacture of dentures is given. Based on the literature data, it can be concluded that despite active development of the technological component of the manufacture of removable dentures, the basic principles of their design, methods of evaluation of the effectiveness and comfort of use have not undergone significant changes. However, there are a significant number of factors whose influence on the success of orthopedic rehabilitation with removable dentures has not been fully studied. For example, orthopedic dentists often do not analyze the volume of atrophy of the bone tissue of the jaws and design the basis of a dental prosthesis without taking these parameters into account. Another important issue that remains not considered is taking into account the design and architectonics of the resulting prosthesis and its effect on the speed and direction of respiratory flows in the oral cavity. All this creates a technological window that allows, due to compliance with the physiological requirements of the factors described above, to significantly increase the functional properties of the denture, to facilitate the patients habituation to the prosthesis by reducing the adaptation period. The research conducted in this area of knowledge will permit to obtain both new scientific data and develop a number of practical recommendations aimed at improvement of the quality of orthopedic rehabilitation using removable dentures made of various materials.

When applying coatings using various methods on the surfaces of moving parts that work in joints, it is important to make sure that the coatings are strong and wear-resistant in order to return them to their original resource. All existing hardening technologies and materials used to perform coatings have their own characteristics, therefore, the quality of the resulting coatings can be judged only after specific tests. (Research purpose) The research purpose is in evaluating the properties of the coating obtained by the method of electric spark hardening, and its ability to resist friction and mechanical wear. (Materials and methods) Authors conducted tests on the basis of the "Nano-Center" center for collective use. A coating was applied on the BIG-4M unit with a VK-8 hard alloy electrode, tribological properties were evaluated on a CSM Instruments TRB-S-DE-0000 tribometer, the width of the friction track was measured after the test using an inverted OLYMPUS gx51 optical microscope, and samples were weighed before and after the test on a VLR-200 analytical balance. Conducted research in accordance with GOST 23.224-86 and RD 50-662-88 guidelines. (Results and discussion) The article presents performed tests on the run-in and wear resistance of the coating. The samples were worked on with a step-by-step increase in the load. During the tests, the friction force was drawed on the diagram. Authors compared the results with the reference sample, an uncoated surface. (Conclusions) The resulting coating has better run-in and wear resistance compared to the standard, and the increase in wear resistance in dry friction conditions is very significant.

The use and quality analysis of household compost have become very important issues in recent years due to the increasing interest in local food production and safe, self-produced food. The phenomenon was further exacerbated by the COVID-19 pandemic quarantine period, which gave new impetus to the growth of small home gardens. However, the knowledge associated with making high-quality compost is often lacking in home gardeners. Therefore, the objective of this research was to find answers to the following questions: can the quality of backyard compost be considered safe in terms of toxicity and nutrient content? Can weed seed dispersion affect the usability of backyard compost? In general, can the circulation of organic matter be increased with the spread of home composting? In this study, 16 different house composts were analysed for stability, weed seed contamination, toxic elements, and nutrient content using analysis of variance. The results of the research showed that the quality properties of the composts (including their weed seed dispersion effect) were greatly influenced by the different techniques and raw materials used. The toxicity levels, as well as the content of macro and microelements, were within the parameters of safe-quality compost. The specific macronutrient (Ca, Mg) and micronutrient (Fe, Mn) contents of the tested composts have a similar and, in some cases, more favorable nutrient supply capacity in crop production than the frequently-used cow manure-based composts. With a plan of basic education on composting, there is potential to encourage farmyard composting.

This research aimed at investigating the effect using molasses and cornmeal as additives with Lactobacillus sp. and Streptomyces sp. as inoculums during fermentation on the quality of silage flour made from dead chickens. The study was conducted using a completely randomized factorial design, consisting of 2 factors with 5 replications. The materials used were the newly dead chickens which were chopped and mixed thoroughly with all ingredients; then transferred into a 5 liters plastic box for fermentation. Observations were made after 3 weeks fermentation, including: a) physical characteristics, b) microbial contents, and c) nutritional contents. The data were calculated using variance analysis utilizing computer program of SPSS version 21.0. It was found that based on the protein contents the Lactobacillus sp. (19.0%) was better than the Streptomyces sp. (17.8%) if combined with molasses and corn meal as the accelerators. However, the fat contents produced were relatively similar for both of the inoculums (mean of 37.8%). It can be concluded that in order to obtain a best fermented product in terms of the protein and fat content, the dead chicken should be fermented using molasses and cornmeal as the accelerator and Lactobacillus sp. as the inoculum.

Agaricus Bisporus is an edible button mushroom that is highly perishable with an extremely short shelf-life at ambient temperature. This work aims to evaluate some antioxidant activities, oxidation enzymes, and determine postharvest qualities of nano-coated mushrooms with the combination of chitosan (CHN) component during storage at 4 °C for (0, 3, 6, 9, and 12 days). Silica/CHN Film strongly delayed the mushroom respiratory spike onset and blocked carbon dioxide passage from inside to the outside, while Titanium/CHN Film (0.035 mmol s−1 kg−1) established the lowest O2 production rate and thiobarbituric acid reactive substances production (6.21 nmol g−1). Silica/CHN Film was mainly effectual for the polyphenol contents (0.39 g kg−1) and antioxidant activities (78.14% and 71.09%) for DPPH and ABTS+ radical scavenging activities, respectively. The results reported that Silica/CHN Film induced the highest (catalase and ascorbate peroxidase) activities, while Titanium/CHN Film recorded the highest (peroxidase and superoxide dismutase) activities of antioxidant enzymes. Besides, Titanium/CHN Film preserved relatively lower contents of hydrogen peroxide (22.40 µmol g−1) and hydroxyl radical (0.16 µmol g−1). In a word, nano-materials used in coating films such as titanium or even silica with the combination of CHN can directly reduce the cell degradation, oxidation processes and enhance the harvested horticultural crops.

<em>Background</em>. The Center for Transfusion Medicine, Cell Therapy and Cryobiology, Milan, Northern Italy, is the headquarter of the POLI-MI biobank. It co-ordinates the biobank activities of the Fondazione Ca’ Granda Ospedale Maggiore Policlinico of Milan. Such activities require specific safeguarding of donors’ rights and protection of sensitive and genetic data. The Fondazione Ca’ Granda Ospedale Maggiore Policlinico has set up a project on informed consent with the aim of developing awareness and understanding of this issue. Within this project, it has been decided to evaluate how consent for biobanking material is expressed. <em>Design and methods.</em> The aim of the study was to evaluate the quality and completeness of consent to biobanking in the POLI-MI biobank. This was a retrospective study carried out in 2012 on samples of consent declarations collected by biobank units in 2011. Some units used a single, standard consent model available from a previous POLI-MI biobank workgroup. Other units used models which had been previouly formulated. Evaluation was made using a form that indicated the essential elements of consent. <em>Results</em>. A total of 48 consent declarations were collected using the single, standard model and 84 were collected using other models. The consent declarations that used the single, standard model were found to be the most complete and were filled in better than other models. <em>Conclusions</em>. Progressive adoption of a simple, standard consent model is expected to improve the quality of consent acquisition. Regular audit of the compliance of consent practices with ethical and legal requirements is mandatory to improve the quality of research biobanking.
