Means Of Production

RESUMO: No momento de instabilidade econômica em que se encontra o país, ações que minimizem os gastos e que aumentem a produtividade na construção civil visando ao desenvolvimento sustentável dos meios de produção estão cada vez mais sendo solicitadas. Com o intuito de realizar um diagnóstico da disposição, organização e práticas nos canteiros de obra da região do Crajubar, foram estudadas dez construções em execução na região. A amostra selecionada contemplava edificações horizontais e verticais, com finalidade de uso comercial, residencial e mista. Os dados foram obtidos a partir do método de diagnóstico que consiste na aplicação de uma lista de verificação (check-list) padronizada, que contemplava três grupos a serem analisados: instalações provisórias, segurança na obra e movimentação e armazenagem de materiais. Para a visualização e identificação de falhas nos canteiros foi feito um registro fotográfico de itens pré-determinados. De posse das informações coletadas foram atribuídas notas para os grupos, calculada a nota global (que é a média aritmética das notas de grupo) e as obras foram distribuídas em quatro categorias: ótimas, boas, regulares e ruins. As obras horizontais obtiveram as piores notas, entre 4,01 e 6, enquanto as obras verticais que apresentavam políticas de gestão de qualidade se destacaram com as melhores notas, entre 8,01 e 10. O tipo de obra foi o fator que mais influenciou na qualidade dos canteiros de obras avaliados no Crajubar cearense.ABSTRACT: At a time of economic instability in the country, actions that minimize expenditures and increase productivity in civil construction aimed at the sustainable development of the means of production are increasingly being requested. In order to make a diagnosis of the layout, organization and practices in the construction sites of the Crajubar region, ten constructions were studied in the region. The sample selected included horizontal and vertical buildings, for commercial, residential and mixed use. The data were obtained from the diagnostic method, which consists of the application of a standardized checklist, which included three groups to be analyzed: temporary installations, handling and storage of materials. Along with this list, a photographic record of predetermined items was made for the visualization and identification of defects in the construction. From the information collected, the group notes and a global grade (the arithmetic mean of the group notes) were assigned and the works were distributed into four categories: great, good, regular and bad. The horizontal construction obtained the worse notes, between 4.01 and 6, while the vertical construction that presented policies of quality management stood out with the best notes, between 8,01 and 10. The type of construction was the factor that most influenced the quality of the construction sites evaluated in Crajubar cearense.

Required Quality

In construction production, the safety of constructing buildings and structures is achieved by ensuring the required quality as a result of systematic construction control based on the implementation of a complex of technical, economic and organizational measures at all stages of the object's life cycle. The article deals with the actual problem of improving the quality of construction products-buildings and structures in conjunction with the activities of construction control bodies. The article presents the advanced foreign and domestic experience of ensuring the quality control at the construction sites, providing for the prevention of the underlying causes of defects and increasing the interest of the contractors directly. On the basis of the analysis of the current situation with quality control at the construction market, ways to improve its efficiency by developing a unified system of technological implementation of relevant requirements for the quality of construction products, determining the rational number and business load of construction control engineers, as well as the active activities of self-regulatory organizations in this area are offered.

The purpose of this study has been to identify the degree of sustainability in the development of the Province of Warmia and Mazury. The theoretical and empirical investigations were conducted between 2003-2014 based on data from the Local Data Bank. Using a comparative indicator method, 20 indicators were developed, with different directions of preference. The evaluation involves the concept of uniform preference, hence the higher the assessment indicator, the better the situation in the evaluated area unit. Our studies on the sustainable development of the Province of Warmia and Mazury suggest that the indicators measuring the environmental dimension and consequently the quality of life of the residents (in this aspect) score higher than the country's average values. It is also optimistic that some progress, however small, can be seen in this area based on the analyzed dynamics of changes.

Harvest quality of sugar beet varies according to soil conditions, harvester type and setting, and variety, too. Harvest quality may affect storage losses, in particular when injuries occur. To determine the harvest quality of commercial sugar beet and to quantify resulting storage losses, 92 commercial sugar beet clamps were sampled across Germany and information about harvest conditions were gathered. At IfZ, soil tare, leaf residues, topping diameter, root tip breakage and surface damage of the beets were determined. The beets were stored in 6 replicates in a climate container at 9°C for 10 weeks. The results demonstrate a rather good harvesting quality of sugar beet in Germany. Soil moisture at harvest did not affect harvest quality and storage losses. Very light, but also heavier soils lead to inferior harvest quality (soil tare, root tip breakage, damage) and slightly higher storage losses compared to the typical loam soils. Significant differences occurred between the three harvester types (companies). In general, high root tip breakage and severe surface damage of the beet was related to a high infestation with mould and rots, high invert sugar contents after storage and high sugar losses. Out of the five most planted varieties, in particular one turned out to be very susceptible to damage, resulting in high storage losses. The factor analysis suggests that the effect of harvester / harvester setting and of variety is more important for harvest quality and storage losses of sugar beet than soil conditions at harvest. Therefore, attention should be paid to optimize these conditions.

Various treatments are carried out in order to extend both the shelf life and storage life of fresh fruit and vegetables after harvest and among them non-toxic for humans, environmentally and economically friendly alternative treatments are gained more importance. In the current study, methyl jasmonate (MeJA), cytokinin, and lavender oil which are eco-friendly and safe for human health were applied on apricot fruit. The treated fruit were stored at 0 °C and 90–95% relative humidity for 25 days and catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) enzyme activities and lipid peroxidation of apricots after treatments were studied. According to the findings obtained from the study, it was observed that 5 ppm cytokinin and 1000 ppm lavender oil treatments of apricot fruit gave better APX and CAT enzyme activity, respectively. In addition, better SOD enzyme activity in fruit was obtained with MeJA+lavender oil treatments. As a result, it can be emphasized that the product quality of apricot fruit is preserved as both the eco-friendly application of MeJA, cytokinin, and lavender oil separately from each other and the treatment of combinations between these compounds activate the enzymatic antioxidant defense systems of apricot fruit after harvest.

The study aimed to assess the effect of herbal additions with antioxidant properties (pepper, thyme and oregano) on the microbiological and oxidative stability as well as the sensory quality of minced poultry meat. Meatballs treatments without additives and treatments with the addition of three types of spices in two forms—dry spices and industrial extracts were examined. Popular seasoning additives of oregano (Origanum vulgare), thyme (Thymus vulgaris) and black pepper (Piper nigrum) at 0.3% of dry herbal or 0.003% as industrial extract were added to minced meat. The microbiological, chemical and sensory tests were performed at specified times and storage temperature. Based on the studied criteria, products maintained constant and adequate quality by up to 10 days while stored in 4 °C. In the case of all tested samples, the overall sensory quality began to deteriorate after 10 days of storage. The preservative role of herbs and extracts in meat products during processing and storage was observed. Oregano and black pepper in both forms maintained good microbial quality and showed their inhibitory effects on the growth of psychrotrophic bacteria. It was observed that dried herbs revealed a stronger antioxidant effect than additives in the form of extracts. The studied dried herbs played an antioxidant, antimicrobial and preservative role in meat products during processing and storage.
