Published: May 2021

In modern conditions of meat production, one of the priorities of the meat processing industry is the production of products with improved consumer properties. To perform this task, it is necessary to include in the industrial circulation of physiologically functional ingredients of plant origin, which will provide the body with nutrients and expand the range of functional foods. The paper covers the issues of partial replacement of raw materials of animal origin with germinated sea-buckthorn seeds (GSBS) flour as a functional ingredient in the production of sausages. The chemical and vitamin composition of the physiologically functional ingredient has been studied. Three experimental recipes for sausages from GSBS flour has been developed. The positive influence of GSBS flour on functional-technological and physical-chemical properties of the received forcemeat is proved. Organoleptic parameters of sausages from GSBS flour are determined. The use of GSBS flour as a functional ingredient in the technology of sausages affects the appearance, taste, smell. It is established that the increase in the amount of GSBS flour introduction leads to an increase in pH by 0.4–0.8 % and finished products by 6.8 %. The improvement of functional and technological properties of experimental minced meat of sausages based on the use of GSBS flour is proved. The optimal amount of replacement of the main raw material with a physiologically functional ingredient, which is characteristic of the experimental sample № 2. The changes in the qualitative characteristics of the developed sample of sausages, which where within the regulatory requirements. The addition of 10 % GSBS flour to the minced meat of sausages leads to a slight increase in protein with a significant reduction in lipid content by 4.4 % in the finished product. As a result, the caloric content of Altaiska functional sausage is reduced by 13.2 % compared to traditional products. Production of such products will allow to expand the domestic range of functional products. Consumption of such sausages allows to consider them as foodstuff with essentially new functional properties which would correspond to modern requirements concerning food.

Published: May 2021

Quick and accurate determination of oil content is extremely important to control the oil content of vacuum fried fruit and vegetable chips. This article uses fresh Pleurotus eryngii as raw materials to explore the influence of different vacuum frying times (0–14 min) on the moisture distribution, oil changes and quality of Pleurotus eryngii strips. The results show that as the frying time increases, the lateral relaxation time required for the taro strips to drop from the highest point of the signal amplitude to smooth becomes shorter and shorter, and the decay rate becomes faster and faster, that is, when the frying time is 14 minutes, The attenuation curvature and velocity are the largest. The oil content and brittleness of Pleurotus eryngii strips are significantly increased (P < 0.05); the water content is significantly reduced (P < 0.05); the hardness first decreases and then increases (P < 0.05); the brightness L* value does not change much, and the color is not Significant change (P > 0.05). At the same time, low-field NMR shows that the high-degree-of-freedom water in the pleurotus eryngii strips migrates to the low-degree-of-freedom water during the vacuum frying process. Among them, the free water in the pleurotus eryngii strips has a large degree of freedom. It has been removed, resulting in poor mobility and increased inability to flow. Part of the free water migrates to the semi-bound water, and most of the semi-bound water migrates outward as free water and then is removed. From this, all peaks are gradually removed. Moving to the left, the total peak area decreases. During the frying process, the T2 relaxation time of Pleurotus eryngii strips all shifted to the left, the total peak area is continuously reduced, the water content is getting less and less, the fat content is getting higher and higher, and the fat content distributed in the edge shell is always higher than Other locations. Low-field nuclear magnetic resonance technology can provide a fast, accurate, and non-destructive method for detecting moisture and grease for the vacuum-fried fruit and vegetable chips. As the frying time increases, the inner contour of the MRI image of Pleurotus eryngii strips gradually becomes blurred, the brightness gradually decreases, the volume shrinks, the less water, and the image interior is close to the background color (blue), indicating that the sample has reached the end of drying; and The grease content is distributed in the edge shell layer higher than other positions. Therefore, the water is continuously removed, the oil signal becomes stronger and stronger, and the oil content of the sample becomes higher and higher.

В этой статье представлен анализ распространения SARS-CoV-2 в Amapá с использованием трех подходов. В первом случае модель пандемии ICL, примененная к Бразилии, использовалась для реализации сравнительного линейного прогноза для населения Amapá. Второй подход был разработан на основе краткосрочного решения стандартной модели SIR, где было показано, что типичное экспоненциальное поведение удовлетворительно описывает данные за первые недели эпидемии, но вскоре после этого появляются ранние расхождения из-за внезапного замедление темпоральной эволюции, количество случаи из-за мер изоляции. Этот новый режим надлежащим образом описывается с помощью третьего подхода, который основан на модели vSIR, которая является вариантом модели SIR. Представленные результаты позволяют, с одной стороны, лучше понять сценарии, с которыми уже сталкивается население, и, с другой стороны, предоставить краткосрочные прогнозы, которые будут постоянно обновляться по ссылке[11].

Este artículo presenta un análisis de la propagación del SARS-CoV-2 en Amapá utilizando tres enfoques. En el primero, partimos del modelo ICL para la pandemia aplicado a Brasil para implementar una proyección comparativa lineal para la población de Amapá. El segundo enfoque se desarrolló con la solución a corto plazo del modelo SIR estándar donde se demostró que el comportamiento exponencial típico describe satisfactoriamente los datos de las primeras semanas de la epidemia, pero poco después, se producen discrepancias tempranas debido a una desaceleración repentina en la evolución temporal del número de casos por medidas de aislamiento. Este nuevo régimen se describe adecuadamente con el tercer enfoque, que se basa en el modelo vSIR, que es una variante del modelo SIR. Los resultados presentados permiten, por un lado, una mejor comprensión de los escenarios ya enfrentados por la población y, por otro lado, proporcionan proyecciones a corto plazo que se actualizarán constantemente en el enlace [11].

Published: May 2021

One of the biggest challenges that public health experts have ever faced is detecting and mitigating the community spread of COVID-19. Current clinical testing of COVID-19 patients is limited in terms of testing kits available, cost logistics, and detecting individuals that are mildly symptomatic and asymptomatic. False positives and false negatives also cloud the true picture of the pandemic. Ontario municipalities’ wastewater systems can provide new testing opportunities for a non-invasive approach in tracking and monitoring the community spread of COVID-19 through sampling raw sludge or untreated wastewater to test for SAR-CoV-2 RNA fragments. Current global and domestic research confirms the effectiveness of wastewater epidemiology surveillance of SAR-CoV-2 and can be detected even before individuals experience symptoms providing a real-time indicator for appropriate public health interventions. In collaboration with the COVID-19 Wastewater Consortium of Ontario (CWCO), an initiative of McMaster University, the objective of this research is to determine the means to optimize the current infrastructure capacity of municipal wastewater systems as an opportunity to monitor and track COVID-19 spread in the community by identifying local realities and risks. To identify local challenges, we distributed a survey amongst Ontario municipalities regarding wastewater treatment plants’ characteristics, held focus group discussions, and implemented an eight-week sampling program with CWCO’s partners. This report focuses on municipal wastewater treatment plants with in-house laboratory facilities to analyze the current capacity and limitations associated with their sampling and analysis programs. Drawing from survey responses and focus group discussions, we revealed gaps for municipalities to move forward with sample testing and data processing as well as governance challenges.

Introdução: A imobilidade no leito de pacientes em unidades de terapia intensiva (UTI) favorece o maior tempo de permanência na unidade. Objetivos: Comparar a funcionalidade na admissão e na alta da UTI segundo a especialidade médica e correlacionar a funcionalidade na alta com o tempo de internação na UTI. Métodos: Estudo exploratório, longitudinal, realizado na UTI Geral de um hospital escola. Os pacientes foram divididos em grupos de acordo com a especialidade de internação: neurologia, pneumologia, gastroenterologia, politrauma e outros. O estado funcional prévio à internação foi obtido por meio da medida de independência funcional (MIF). Na alta foi aplicada a escala de mobilidade funcional em UTI (EMU). Resultados: Amostra de 174 pacientes, 53% do sexo masculino. O grupo politrauma apresentou idade significativamente menor que os outros grupos (p < 0,0001). O tempo médio de internação para os grupos neurologia e pneumologia apresentou correlação inversamente proporcional com p = 0 ,02 / r = -0,5 e p = 0,009 / r = -0,4 respectivamente. Não houve diferença significativa entre as médias da MIF na admissão (p = 0,11) e da EMU na alta (p = 0,24) entre as especialidades médicas em que os pacientes foram admitidos. Conclusão: Quanto maior o tempo de internação na UTI, menor a funcionalidade na alta em pacientes neurológicos e pneumopatas.

This research focuses on the Formulation of Regional Regulation Policy Number 3 of 2017 concerning the Riau Malay Customary Institution, Dumai City. This study aims to examine the process of formulating a Perda policy by the Dumai City DPRD and related institutions. This study used a descriptive qualitative approach, in which the informants were determined by purposive sampling from various related agencies. The results of the study found that the process of determining Perda policies follows the direction of the prevailing laws, but the compilation process has not been carried out in a holistic manner, it is lacking in depth, especially in the phase of setting the policy agenda. In this context, it was found that the identification of the problem was not very deep related to the problems and peculiarities of the local cultural, customary and historical conditions. Apart from the Perda, there is also no clear framework for protecting, defending and fighting for the fate of indigenous peoples and local communities. Furthermore, in the drafting phase, it has not yet mobilized public participation, including providing public space and public discussions. In fact, this shows the openness in the formulation phase of the Perda. The interesting thing here is that the concept of the Perda in broad terms refers too much to the Perda of the Riau Provincial Malay Customary Institution. So it is advisable to clarify the concept and frame work "so that it is affective in achieving the mission and goals of the Riau Malay Customary Institution. This study concludes that the Perda is more oriented towards micro interests, namely internal organizations, besides the need to have a legal basis, it can also be used as a basis for obtaining grant allocation from the Dumai City APBD.

Published: May 2021

The purpose of this work is to substantiate the possibility of using a new composite sintered in the "diamond-carbonate" system for equippingdiamond drilling tools with high wear resistance and efficiency of rock destruction. The research technique consisted in establishing the influence of the wear resistance of the cutting edge of the samplesof a superhard composite diamond-containing material on the efficiency of rock destruction, assessed by the granulometric composition of its sludge. Research results. The two-phase superhard composite materials diamond – CaMg(CO3)2 and diamond – SrCO3 were obtained as a result of sintering by the method of impregnation of diamond micropowder with carbonate melts under conditions of a high pressure of 8.0 GPa and a temperature of 2100 °C. Wear resistance of the investigated composite sampleswas determined by based on the results of turning the core of granite from the Korostyshevskoye deposit of the X category of drilling. Determination of the size and shape of particles of granite fragments of the Korostyshevskoye deposit, taken during its destruction was carried out by laser diffraction and digital image analysis using a Microtrac Sync analyzer.The relationship between the degree of its wear of the cutting edge of composite samplesand the energy consumption of rock destruction, the size distribution of particles in the cuttings sample and their specific surface was established after analyzing the results of the study of wear resistance and the nature of their wear. Plates of the diamond–CaMg(CO3)2 composite, which have a higher wear resistance compared to other composites, are characterized by an increase in the proportion of large particles in the cuttings sample and a decrease in the value of their specific surface, which indicates a more rational use of energy, which goes to a greater extent for destruction rock and to a lesser extent for friction and wear. Practical value. The research results allow us to make a conclusion about the advisability of equipping a drilling rock cutting tool with samplesof a diamond–CaMg(CO3)2 composite in order to increase its wear resistance and the efficiency of rock destruction.

Published: May 2021

Purpose. To propose a new methodological approach to optimizing the parameters of the functioning of coal mines in the context of diversification. The methods. The production flows of coal mines are considered, as well as production functions. To solve the problem of diversification of production, the relationship between the types of resources expended, as well as the level of production in the form of raw materials, was compared. Based on the production function of Cobb-Douglas, a model of life support for the operation of a coal mine is built, considering the possibility of diversifying the activity. Findings. For the first time, the paper proposes a model for optimizing the parameters of mining in the context of diversification, which demonstrates the ratio of production functions and resources. With the help of the developed model, it is possible to trace in time the efficiency of the use of production resources, to determine the volume of production, to calculate the main parameters of the functioning of coal mines, to study at the expense of which resources the increase in productivity is achieved. The originality. For the first time, the possibility of diversifying mining activities by changing production flows is considered. Methodological recommendations for assessing the production activity of the mining complex are given. In this work, for the first time, to improve the efficiency of coal mines functioning, the internal potential of the technological scheme is considered, and the components that form it are analyzed. This made it possible to form management decisions, which consist in determining the volume of production, as well as the ratio between the attracted resources necessary to ensure the specified volume of production, constant monitoring of the use of resources, by establishing a rational ratio between fixed assets, labor, material resources; as well as establishing the interchangeability of productive flows in the aggregate balance sheet. Practical implementation. For practical application, the paper proposes a method for determining the rational volume of production from the standpoint of optimizing the production activities of an enterprise, as well as the ratio of production resources to achieve a given scale of production. Thus, there is an increase in capital productivity with the same degree of use of fixed assets, labor, materials. For the full and effective use of the technology, a specific example was considered to determine the optimal method of manufacturing products for a coal mining enterprise.

La justicia conmutativa y el principio del sinalagma en los contratos de trabajo con relación a la estabilidad laboral
Authors: D’Ambrocio-Camacho Diana
Published: May 2021

El derecho actual en su estructura cuenta no solo con reglas sino también con principios que subyacen en las legislaciones contemporáneas, uno de ellos es el tradicional principio de la reciprocidad en los cambios o sinalagma, que se centra en las relaciones interpartes y determina la existencia de contraprestaciones recíprocas entre los contratantes. Ahora bien, en cuanto una de los intervinientes incumple con la contraprestación recíproca derivada de la relación jurídica alcanzada por el acuerdo de voluntades, genera un acto injusto que da paso al derecho del agraviado a solicitar su reparación y la consecuente obligación de la contraparte a pagar. En este sentido, la contraprestación no necesariamente es proporcional, es decir, no es geométrica como lo referiría Aristóteles, sino que es aritmética, ya que mira a las partes como iguales, se centra en el daño ocasionado y busca restablecer el derecho objetivo y la igualdad, que puede ser mediante el pago de una indemnización, con el objeto de materializar la justicia conmutativa o correctiva, para alcanzar el ideal de justicia y bien común, conforme lo expone Santo Tomás de Aquino. En este contexto, la estabilidad laboral de los trabajadores, puede ser estudiada superando la barrera que limita el conocimiento al principio protectorio y los sub-principios que lo integran y trascender al análisis del principio de antropía y principalmente el de reciprocidad en los cambios o sinalagma, que resalta la naturaleza y especificidad de las relaciones que derivan de la prestación del trabajo, reconocido como el esfuerzo físico o intelectual que se presta a cambio de una remuneración.

Published: May 2021

La expansión de la elección de escuelas en la última década, ha debilitado el fuerte vínculo entre los vecindarios y las escuelas creado bajo un estricto sistema de asignación de escuelas basado en la residencia, desacoplando las decisiones de inscripción residencial y escolar para algunas familias. Un trabajo reciente sugiere que el vínculo entre el vecindario y la escuela se está debilitando más en los vecindarios rurales (gentrificación). Se analizó una combinación novedosa de datos individuales, escolares y del vecindario que vinculan a los niños con las escuelas asignadas y matriculadas mediante un método cuantitativo. El objetivo de este estudio fue examinar los factores familiares, escolares y del vecindario que determinan si los padres se inscriben en la escuela local asignada. Se verificó que, es más probable que los padres opten por no participar en las escuelas de vecindarios gentrificados en comparación con vecindarios urbanos de elección cercana con disponibilidad. Se concluye que, existe una tendencia de elección de escuela de cambio urbano al dejar de lado los vínculos del vecindario.

Abstrak. Indonesia sebagai bangsa yang beranekaragam mulai dari suku, ras, agama, bahasa dan adat istiadat. Karena dari hal tersebutlah muncul kebudayaan-kebudayaan yang diciptakan oleh masyarakat indonesia itu sendiri, bahasa memiliki jalinan yang sangat erat dengan budaya sehingga keduanya tidak dapat dipisahkan, karena begitu eratnya jalinan antara bahasa dan budaya. Tanpa bahasa, budaya kita pun akan mati. Hal ini bisa terjadi karena, sebagaimana dikatakan oleh Purwo (2000:3) bahasa adalah penyangga budaya, sebagian besar budaya terkandung di dalam bahasa dan diekspresikan melalui bahasa, bukan melalui cara lain. Ketika kita berbicara tentang bahasa, sebagian besar yang kita bicarakan adalah budaya. Ketika seseorang menggunakan bahasa untuk berkomunikasi dengan orang sekelilingnya, dan kemungkinan orang lain yang berbeda bahasa juga. Ada dua kemungkinan yang terjadi yaitu yang apakah seseorang itu mempertahankan bahasanya atau bahasa yang digunakannya mulai bergeser dengan bahasa lain.Â  Banyak sekali faktor penyebab pergeseran dan pemertahanan bahasa.Kata Kunci : Pemertahanan, Pergeseran Bahasa Daerah Masyarakat Pentingsari Abstract. Indonesia as a diverse nation ranging from ethnicity, race, religion, language and customs. Because of the emergence of cultures created by Indonesian society itself, language has a very close relationship with culture so that they cannot be separated, because so closely the relationship between language and culture. Without language, our culture will die. This can happen because, as Purwo (2000: 3) says, language is a support for culture, most cultures are contained in language and expressed through language, not through other means. When we talk about language, most of what we talk about is culture. When someone uses language to communicate with people around him, and possibly other people with different languages too. There are two possibilities that occur, which is whether someone maintains his language or the language he uses begins to shift with other languages. There are many factors that cause shifting and language retention.Keywords: Defense, Shifting Regional Languages of the Pentingsari Society
