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.

Lactic acid bacteria (LAB) are naturally associated with many foods or their raw ingredients and are popularly used in food fermentation to enhance the sensory, aromatic, and textural properties of food. These microorganisms are well recognized for their biopreservative properties, which are achieved through the production of antimicrobial compounds such as lactic acid, diacetyl, bacteriocins, and other metabolites. The antifungal activity of certain LAB is less well characterized, but organic acids, as yet uncharacterized proteinaceous compounds, and cyclic dipeptides can inhibit the growth of some fungi. A variety of microbes are carried on raw materials used in beer brewing, rendering the process susceptible to contamination and often resulting in spoilage or inferior quality of the finished product. The application of antimicrobial-producing LAB at various points in the malting and brewing process could help to negate this problem, providing an added hurdle for spoilage organisms to overcome and leading to the production of a higher quality beer. This review outlines the bioprotective potential of LAB and its application with specific reference to the brewing industry.

The results of the study of the natural sweetener effect from Stevia on the quality of two types of table semisweet fruit blended wine - from gooseberries and raspberries, gooseberries and black currants - in comparison with the classical recipe with sugar, are presented in the article. The recipes and the production technology of table blended fruit wine with Stevia extract as a sweetener were presented in the work. Stevia extract and sugar (control sample) were added after complete fermentation of sugars into dry wine material. The extract dose was 1.4 ml per 1 liter of wine material. Organoleptic and tasting evaluation of the finished product showed that wine with the addition of Stevia extract has good quality indicators, a pleasant taste without extraneous smacks. The sugar content was practically at zero point - 0.25 g / l in wine from gooseberries and raspberries, 0.28 g / l in wine from gooseberries and black currants. In the wine made by classical technology, the sugar content was 70.30 g / l and 71.10 g / l, respectively. The titrated acidity of the wine was within the requirements of the regulatory document and ranged from 9.0 to 10.9 g / dm3. The content of vitamin C and beta-carotene depended to a greater extent on the type of fruit and berry raw materials used. A higher content of ascorbic acid was noted in blended wine from gooseberries and black currants - at the level of 26.88–27.02 mg, beta-carotene - in wine from gooseberries and raspberries. The introduction of sugar or Stevia extract did not affect the values of these indicators much. According to the results of studies in the manufacture of blended fruit wines in order to reduce their calorie content and use as a functional product, the addition of Stevia extract is recommended

The effectiveness of an amine-negative starter culture (Lactobacillus sakei CTC494) in the reduction of biogenic amine production during the ripening of fermented sausages was examined. Four batches were manufactured in parallel:spontaneously fermented and starter-mediated sausages were manufactured from two lots of raw materials of different hygienic quality. Besides the biogenic amine contents, changes in the microbial counts, nitrogenous fractions, pH, and water content were measured at several sampling points during the ripening process. In sausages manufactured from good quality meat, the starter strain of L. sakei reduced and even inhibited biogenic amine accumulation during sausage fermentation, the end products showing extremely low biogenic amine contents (tyramine levels less than 15 mg/kg of dry matter and putrescine and cadaverine levels less than 5 mg/kg of dry matter). Nevertheless, starter-mediated sausages made from poorer-quality raw materials showed much higher amine contents (308, 223, and 36 mg/kg of dry matter of cadaverine, tyramine, and putrescine, respectively), which were only slightly lower than those of the spontaneously fermented sausages made from the same raw materials. The relatively high bacterial numbers of raw materials of poorer-hygienic quality diminished the beneficial effect of the starter strain. Therefore, the effectiveness of the starter was strongly dependent on the hygienic quality of the raw materials used.

A study into the failure causes of mixing and charging equipment confirms that the main impact on the probability of accidents is the use of raw materials that do not meet the specifications and have unstable properties. The raw materials used for explosives preparation in mechanized charging of boreholes include such components as ammonium nitrate, emulsion phase, diesel fuel, emulsifier and others. The paper describes the application of various formulations with these components in specific types of mixing and charging machines manufactured by AZOTTECH LLC. The main properties that affect the quality of raw materials are summarised, and the incoming inspection of explosive components is described as part of the acceptance procedure at temporary storage sites at a hazardous production facility. The paper describes common types of equipment failures and maintenance procedures when using substandard raw materials. The conclusion highlights the key practices to improve the equipment uptime as well as recommendations for incoming inspection and the use of high-quality explosive components.

The Impact

Abstract The Retired Senior Volunteer Program (RSVP) is a national program with many regional offices that offers a variety of volunteer opportunities for seniors. Research demonstrates the importance of volunteering and social participation on the well-being, health and longevity of older individuals. Further, studies of RSVP volunteers have demonstrated marked improvement in their perceived physical, mental health and quality of life (McDonald et al., 2013). Little evidence exists, however, supporting the effectiveness of using senior volunteers to assist with or even lead activities programming for persons with dementia (PWDs). Seniors Making Connections through Music, a group program designed to engage persons in the moderate to advance stages of dementia, included the training of 21 RSVP volunteers to lead or assist with the program. Volunteers were mostly female (95%) and educated (80% college/advanced degree), with more than half reporting professional or personal experiences with dementia (62%). Data were gathered through structured interviews and post-session debrief meetings. Findings suggest volunteers felt they were able to use existing knowledge and experience, received good and helpful supervision, and reported increased knowledge of dementia after volunteering for the group. Other results summarize: Volunteer satisfaction with program, role, tools and materials used, the program’s impact on the community, and willingness to volunteer for the program in the future. Programmatic features, training protocols, and the impact of using retired senior volunteers to strengthen program sustainability will be discussed. Volunteer testimonials and video demonstrations will also be shared.

Background: The ability to save the life of an extremely premature baby has increased substantially over the last decade. This survival, however, can be associated with unfavourable outcomes for both baby and family. Questions are now being asked about quality of life for survivors of extreme prematurity. Quality of life is rightly deemed to be an important consideration in high technology neonatal care; yet, it is notoriously difficult to determine or predict. How does one define and operationalise what is considered to be in the best interest of a surviving extremely premature baby, especially when the full extent of the outcomes might not be known for several years? Research question: The research investigates the caregiving dilemmas often faced by neonatal nurses when caring for extremely premature babies. This article explores the issues arising for neonatal nurses when they considered the philosophical and ethical questions about quality of life in babies ≤24 weeks gestation. Participants: Data were collected via a questionnaire to Australian neonatal nurses and semi-structured interviews with 24 neonatal nurses in New South Wales, Australia. Ethical considerations: Ethical processes and procedures have been adhered to by the researchers. Findings: A qualitative approach was used to analyse the data. The theme ‘difficult choices’ was generated which comprised three sub-themes: ‘damaged through survival’, ‘the importance of the brain’ and ‘families are important’. The results show that neonatal nurses believed that quality of life was an important consideration; yet they experienced significant inner conflict and uncertainty when asked to define or suggest specific elements of quality of life, or to suggest how it might be determined. It was even more difficult for the nurses to say when an extremely premature baby’s life possessed quality. Their previous clinical and personal experiences led the nurses to believe that the quality of the family’s life was important, and possibly more so than the quality of life of the surviving baby. This finding contrasts markedly with much of the existing literature in this field. Conclusion: Quality of life for extremely premature babies was an important consideration for neonatal nurses; however, they experienced difficulty deciding how to operationalise such considerations in their everyday clinical practice.
