Theoretical basics and technological characteristics of pork with typical syndromes
Get PDFIn the practice of meat processing, pork is often characterized by such syndromes as PSE (pale, soft, exudative), DFD (dark, firm, dry) and RSE (reddish-pink, soft, exudative). They worsen the perception of meats and have a negative impact on their technological properties in the production of meat products. In the total amount of pork used as raw material, meat with PSE and DFD syndromes features up to 50%. Studies have shown that PSE pork differed from quality meat (NOR) in a less elastic texture, the cut surface was soft, exudative, pale pink in color, and DFD pork was distinguished by a darker color. Compared to NOR meat, the pH value of pork DFD decreases during storage, while that of pork PSE increases. By appointing optimal feeding rations with the minimum necessary use of veterinary preparations, minimizing the causes of pig stress, choosing rational slaughter methods and regimens, it is possible to limit the impact of PSE syndrome and other common meat defects and improve pork quality
Justification of the dibber drill machines wheel parameters under the condition of rotation uniformity
Get PDFThe article presents theoretical and experimental study results of rotation uniformity for seed drill wheel and possibilities of using wheeled dibber drills in the design of sowing machines. The main purpose of research is to obtain mathematical models of wheel dynamic model expressing the dependence of wheel sliding on the technological and design factors. The objectives were to determine rolling coefficients in order to use their numerical characteristics in the analysis of wheel dynamic model and in particularity, the axial load, wheel radius, parameters of the dibber drills wheel and speed of movement. Freely rotating wheels with a rim width of 170 mm and diameters of 524 mm and 712 mm were used in the experiments. Soil in the channel was brought close by properties to the soil prepared for sowing. Measurement of the driving force was made by strain gauge equipment at a wheel speed of 0.47 m/s. The optimal axial load at the masses of 35-55 kg and diameter in the range of 500-800 mm of thewheeled dibber drills was determined. It was proved, that wheel slip within 10-12% will assure the quality of sowing crops technological process execution at speeds up to 3 ms-1. Numerical values of wheel sliding coefficients are on average 58% lower for rolled soil than for loose soil for equal conditions. 
Stimulating circular economy in the food industry: a comparative analysis of the governance strategies in Greece and Armenia
Get PDFThe success of transformation to a circular economic model mainly depends on effective government interventions. The objective of this paper is to reveal the implementation schemes, actors in charge, and funding mechanisms of the circular economy action plan in Greece. Additionally, a comparison has been made concerning the waste management governance practices in Armenia given a few distinct political, social, economic and behavioral characteristics common to both countries. Special emphasis was put on the food industry, since it generates a large amount of waste annually with limited by-product valorization and recycling rate. A comprehensive document analysis has been conducted with deductive or concept-driven approach using the software Atlas.ti. Research results highlighted several deficiencies existing within the policy papers and a set of recommendations covering critical success factors such as education, finance, cooperation, market development, monitoring, and evaluation related to the system change were offered. By addressing these deficiencies, policymakers may ensure an environment conducive to circularity practices and facilitate the transition to a more sustainable and resource-efficient economy
Republic of Moldova: Assessment of energy poverty
Get PDFEnergy poverty is a topic addressed every time when it comes to supplying residential customers with energy - either from traditional or from renewable sources. In the context of the preparations of the Republic of Moldova for the accession to the EU, it is relevant to evaluate the structure of energy consumption of households in the country, the level of related costs, as well as the level of energy poverty. The paper presents data on the evolution of household energy consumption for the period 2010-2020. For a reference year (2019), the level of poverty in the country was assessed under different aspects (by living environment – urban and rural, by socio-economic status (5 categories), by household size (5 cat.) etc.). From the calculations, the average value of the level of energy poverty, characteristic to the Republic of Moldova, as a whole, for the year 2019, was equal to 15.7 % and a slightly higher value for the urban area. The paper also presents the new government initiative to support energy-vulnerable households - the "Help at the meter" program
