Качество и безопасность зерна выступает важным и обязательным объектом государственного регулирования и контроля. Рост количества опасных видов сорных растений, вредных насекомых и заболеваний зерновых культур привел к снижению качества зерновой массы, повышению ее микробиальной обсемененности. Важным этапом снижения микробиальной обсемененности зерна является его подготовка к переработке. Для повышения эффективности сепарирования и поверхностной очистки зерна пшеницы и снижения его микробиологической обсемененности учеными Кубанского государственного технологического университета предложена технологическая линия, включающая установку фотоэлектронного сепаратора перед овсюгоотборником для очистки зерновой массы от примесей, отличающихся от зерна пшеницы по цвету, и шлифовального агрегата вместо обоечных машин для очистки поверхности зерна. Цель настоящего исследования – определить эффективность применения предложенной технологии подготовки зерна пшеницы к помолу на примере его микробиологических показателей безопасности. В качестве объектов исследования были образцы зерна пшеницы из партий, поступивших с элеватора в подготовительное отделение мельницы, отобранные на зерноперерабатывающих предприятиях Краснодарского края, работающих как по традиционной, так и по усовершенствованной технологии. Установлено, что в зерновой массе, подготовленной к помолу по разработанной технологии, общее количество бактерий на 65% меньше, а содержание дрожжей и плесеней соответственно в 2 и 3 раза ниже, чем в зерновой массе, подготовленной к переработке по традиционной технологии. Из зерновой массы, подготовленной к переработке по усовершенствованной технологии, были полностью удалены вредные и минеральные примеси, фузариозные зерна и куколь. Результаты исследования показали высокую эффективность применения разработанной технологии подготовки зерна пшеницы к помолу. The quality and safety of grain is an important and mandatory object of state regulation and control. The increase in the number of dangerous species of weeds, harmful insects and diseases of grain crops has led to a decrease in the quality of grain mass, an increase in its microbial contamination. An important step in reducing the microbial contamination of grain is its preparation for processing. To increase the efficiency of separation and surface cleaning of wheat grain and reduce its microbiological contamination, scientists of the Kuban State Technological University have proposed a technological line that includes the installation of a photoelectronic separator in front of the oat collector to clean the grain mass from impurities that differ from wheat grain in color, and a grinding unit instead for cleaning the grain surface. The purpose of this study is to determine the effectiveness of the proposed technology for preparing wheat grain for grinding on the example of its microbiological safety indicators. The objects of the study were samples of wheat grain from batches received from the elevator to the preparatory department of the mill, selected at grain processing enterprises of the Krasnodar region operating both according to traditional and improved technology. It was found that in the grain mass prepared for grinding according to the developed technology, the total number of bacteria is 65% less, and the content of yeast and mold respectively is 2 and 3 times lower than in the grain mass prepared for processing according to traditional technology. Harmful and mineral impurities, fusarium grains and Agrostemma L. were completely removed from the grain mass prepared for processing using improved technology. The results of the study showed the high efficiency of the application of the developed technology for preparing wheat grain for grinding.

Solar energy is one of the more attractive renewable energy sources that can be used as an input energy source for heat engines. In fact, any heat energy sources can be used with the Stirling engine. Stirling engines are mechanical devices working theoretically on the Stirling cycle, or its modifications, in which compressible fluids, such as air, hydrogen, helium, nitrogen or even vapors, are used as working fluids. When comparing with the internal combustion engine, the Stirling engine offers possibility for having high efficiency engine with less exhaust emissions. However, this paper analyzes the basic background of Stirling engine and reviews its existing literature pertaining to dynamic model and control system for parabolic dish-stirling (PD) system.

This chapter examines how regulation from the state can shape conditions and practices for welfare professions. New members of the European Union, such as Poland, often lack a tradition of social work as an integral part of the welfare state. Challenges for these countries are both to educate social workers and to create legislative solutions stipulating the responsibilities and professional jurisdiction of the social work profession. In the chapter, it is argued that strong regulation and control from the Polish government has resulted in the standardisation of social work. This has curtailed professional autonomy in a manner that is unfavourable to social workers as well as to clients.

There is a growing interest in laser radioactive decontamination of metal surfaces. It offers advantages over conventional methods: improved safety, reduction of secondary waste, reduced waste volume, acceptable cost. The main mechanism of cleaning by lasers is ablation. Apulsed TEACO2 laser was used in this work for surface cleaning in order to show that ablation of metal surfaces is possible even at relatively low pulse energies, and to suggest that it could be competitive with other lasers because of much higher energy efficiencies. A brief theoretical analysis was made before the experiments. The laser beam was focused using a KBr-lens onto a surface contaminated with 137 Cs (b-, t1/2 = 30.17 y). Three different metals were used: stainless steel, copper and aluminium. The ablated material was pumped out in an air atmosphere and transferred to a filter. The presence of activity on the filter was shown by a germanium detector-multichannel analyzer. The activity levels were measured by a GM counter. The calculated decontamination factors and collection factors showed that ablation occurs with a relatively high efficiency of decontamination. This investigation suggests that decontamination using a CO2 laser should be seriously considered.

The phenomenon of phishing has now been a common threat, since many individuals and webpages have been observed to be attacked by phishers. The common purpose of phishing activities is to obtain user’s personal information for illegitimate usage. Considering the growing intensity of the issue, this study is aimed at developing a new hybrid rule-based solution by incorporating six different algorithm models that may efficiently detect and control the phishing issue. The study incorporates 37 features extracted from six different methods including the black listed method, lexical and host method, content method, identity method, identity similarity method, visual similarity method, and behavioral method. Furthermore, comparative analysis was undertaken between different machine learning and deep learning models which includes CART (decision trees), SVM (support vector machines), or KNN ( K -nearest neighbors) and deep learning models such as MLP (multilayer perceptron) and CNN (convolutional neural networks). Findings of the study indicated that the method was effective in analysing the URL stress through different viewpoints, leading towards the validity of the model. However, the highest accuracy level was obtained for deep learning with the given values of 97.945 for the CNN model and 93.216 for the MLP model, respectively. The study therefore concludes that the new hybrid solution must be implemented at a practical level to reduce phishing activities, due to its high efficiency and accuracy.

Theoretical investigations of the ejector refrigeration system using hydrofluoroolefins (HFOs) and hydrochlorofluoroolefin (HCFO) refrigerants are presented and discussed. A comparative study for eight olefins and R134a as the reference fluid was made on the basis of a one-dimensional model. To facilitate and extend the possibility of comparing our results, three different levels of evaporation and condensation temperature were adopted. The generator temperature for each refrigerant was changed in the range from 60 °C to the critical temperature for a given substance. The performed analysis shown that hydrofluoroolefins obtain a high efficiency of the ejector system at low primary vapor temperatures. For the three analyzed sets of evaporation and condensation temperatures (te and tc equal to 0 °C/25 °C, 6 °C/30 °C, and 9 °C/40 °C) the maximum Coefficient of Performance (COP) was 0.35, 0.365, and 0.22, respectively. The best performance was received for HFO-1243zf and HFO-1234ze(E). However, they do not allow operation in a wide range of generator temperatures, and, therefore, it is necessary to correctly select and control the operating parameters of the ejector.

This letter aims to explain the importance of using cell phones to take helpful images with high efficiency in various types of dental procedures. In our dental practices’ photography is an effective tool. Its applications are widespread such as in the diagnosis and treatment planning, keeping an illustrative clinical history, legal documentation, publishing, and delivering lectures.1 In modern dentistry, photography has grown into a standard of treatment. With the advent of digital technology these days, photography has now become simpler and widely available. Even then, few practitioners introduce them in their daily practices due to reasons such as a lack of expertise in cameras, lenses, and technique, disruption of workflow, and cost considerations. The use of smartphones with improved technology, however, is constantly emerging. It allows every practitioner with minimal interruptions in their patient workflow to incorporate photography into his or her practice.2 Making images from mobile in dentistry has multi-level importance. Its implementation in dental practice is simple, swift, and extremely useful in recording working practices, conducting health promotion sessions, and administering clinical examinations, thus providing dentists and patients with many advantages.1-2
