Authors: Lazarte JMT , Liston GC
Published: June 2023

This study aims to calculate the thermal conductivity and vibrational density of states of CdTe using MD simulation. The lengths of CdTe varied from 10 nm, 20 nm, 30 nm, 40 nm, and 50 nm, with fixed width and height of 10 nm at room temperature (300 K). The results show the decrease of thermal conductivity as a function of length due to phonon-phonon interaction. The width varied from 10 nm, 20 nm, 30 nm, 40 nm, and 50 nm at room temperature (300 K) with a fixed length and height of 10 nm. Similarly, the height varied from 10 nm, 20 nm, 30 nm, 40 nm, and 50 nm with fixed length and width at room temperature (300 K).  It was found that the phonon spread less in the boundaries of the mean free path which follows the creation processes resulting to the decrease of thermal conductivity. The temperatures varied from 50 K, 75 K, 100 K, 300 K, 500 K, 700 K, 900 K, 1,000 K, and 1,365 K with fixed dimensions of 50 nm in length, 50 nm in width, and 50 nm in height. As observed, the thermal conductivity decreases with a further increase in temperature. There were four major peaks found in the vibrational density of states of cadmium telluride: ~1.3 THz and ~3.5 THz which corresponds to transverse and longitudinal acoustic modes, ~4.5 THz and ~5 THz which corresponds to transverse and longitudinal optical modes.

This paper presents the method of cryogenic extraction by means of liquefied freons. Using the equipment to extract lipid fractions from biological raw materials, a freon extract from bay leaves (Laurus nobilis) was experimentally obtained. A low-temperature extraction of lipid fractions from bay leaves was first realized using liquefied freons within the temperature range of –2...–8°С. The difference in composition of these fractions from that of the oils, obtained within the standard temperature ranges of 30...50°С was shown. Dependence of the finished product weight on extraction time as a result of three consecutive cycles of 23 hrs each was demonstrated. Using gas chromatography, 68 components of freon extract were identified, and their quantitative composition and dominant compounds were detected. The content of essential oils and aroma-forming substances, stipulating the number of odour units was specified. These findings may be the basis for novel technological approaches to separation of lipid fractions, isolated from biological raw materials of plant and animal origin. Here, we described the device version with a three-stage cryogenic system of freon solvent recovery for effective implementation of the designed technology. Key words: bay leaf, low-temperature technologies, liquefied freon R406A, extract, gas chromatography, number of odour units.

According to scientists, a significant role in the progression of chronic pancreatitis (CP) and diabetes mellitus (DM), as well as in the occurrence of complications of these diseases, is played by inflammation and endogenous intoxication by the products of protein breakdown as a result of the inflammatory process, fibrosis, and degradation of connective tissue in the patient’s body, in particular, and in the pancreas. The aim is to analyze the state of parameters of inflammation, endotoxicosis, and their influence on the functional capacity of the pancreas in the comorbid course of chronic pancreatitis and type 2 diabetes mellitus (DM2). Materials and methods. 112 patients with CP in the phase of mild therapeutic exacerbation in combination with DM2 in the stage of subcompensation were examined. The results. Moderate and moderate inverse correlations were established between CRP and fecal α-elastase in patients with CP and comorbidity of CP and DM2 (respectively r=-0.423 and r=-0.565, p<0,05). An increase in the strength of reliable direct moderate correlations between the levels of HbA1c and CRP in patients with CP in combination with DM2 compared to those with isolated CP (respectively r=0.313 and r=0.410, p<0,05) was proved. Conclusions: We proved a reliable influence of the index of endogenous intoxication on the level of pancreatic functional insufficiency according to the content of fecal α-elastase, which was more significant in the combined course of CP and DM2 compared to that in isolated CP. An increase in the strength of reliable direct, moderate, and moderate correlations between HbA1c levels and the index of endogenous intoxication in patients with isolated CP and CP in combination with DM2 has been proven.

Published: June 2023

Current epidemiological and clinical data confirm the relationship between chronic heart failure (CHF) and osteoporosis (OP), which cannot be explained only by aging and the use of pharmacological drugs. Clinical and epidemiological studies show that CHF is most often accompanied by low bone mineral density, a high risk of fractures and, moreover, a fourfold increase in the risk of any fracture requiring hospitalization. Further research on the relationship between CHF and OP is needed, as understanding the common mechanisms of disease development will serve as a platform for preventive and therapeutic interventions aimed at both conditions.

Guidance from the American Academy of Pediatrics (AAP) for the use of palivizumab prophylaxis against respiratory syncytial virus (RSV) was first published in a policy statement in 1998. AAP recommendations have been updated periodically to reflect the most recent literature regarding children at greatest risk of severe RSV disease. Since the last update in 2014, which refined prophylaxis guidance to focus on those children at greatest risk, data have become available regarding the seasonality of RSV circulation, the incidence and risk factors associated with bronchiolitis hospitalizations, and the potential effects of the implementation of prophylaxis recommendations on hospitalization rates of children with RSV infection. This technical report summarizes the literature review by the Committee on Infectious Diseases, supporting the reaffirmation of the 2014 AAP policy statement on palivizumab prophylaxis among infants and young children at increased risk of hospitalization for RSV infection. Review of publications since 2014 did not support a change in recommendations for palivizumab prophylaxis and continues to endorse the guidance provided in the 2021 Red Book.
Drought and Flood Disaster Control of Agricultural Land and Optimization Method of Planting Structure to Avoid Disaster
Authors: Zhang Yi
Published: June 2023

Agricultural disasters frequently occur in China. Therefore, this article studied the prevention and control of drought and flood disasters in agricultural land and the optimization method of planting structures to avoid disaster. Firstly, the impact of the change of input structure on the prevention and control of drought and flood disasters on agricultural land was analyzed, and the evaluation system of input-output efficiency was constructed. Secondly, the evaluation model was built by DEA method, so as to provide the theoretical basis for the quantitative evaluation of input-output efficiency. Taking Jiangxi Province as an example, the input-output data of drought and flood control of agricultural land in twenty cities in 2014-2017 was analyzed. The results show that the input-output efficiency of 80% of farmland in Jiangxi Province is low, and the resources of drought and flood prevention are not sufficiently utilized. In addition, the low pure technical efficiency and scale efficiency are the main reasons for the low input-output efficiency of drought and flood prevention. The effect of human and financial input in drought and flood prevention of farmland in Jiangxi Province is slightly different for value output and actual output. From the aspects of strengthening the investment in basic facilities and the technical research and development of agricultural products, the optimization strategy for the input structure of drought and flood prevention of agricultural land is put forward.

Authors: Shalavina Ekaterina V. , Vasilev Eduard V. , Papushin Eduard A.
Published: June 2023

Introduction. There is not enough data on the used intensive technologies of processing pig manure into organic fertilizer to accurately calculate the content of nutrients in the final products and, accordingly, their doses of application.
Aim of the Article. To determine the efficiency of pig manure processing technology, which includes liquid fraction rectification, by the quantitative and qualitative characteristics of manure and final products, and to trace the redistributing total nitrogen between the final products on the example of a pilot pig breeding complex production.
Materials and Methods. For the study, there was chosen a typical pig-breeding complex, where the pig manure processing included slurry acidification, flocculation, separation into fractions in a decanter centrifuge, rectification of liquid fraction, passive composting of solid fraction, and long-term storing of liquid fraction. The technology allows producing three types of end products: solid organic fertilizer, concentrated liquid (ammonia water), and fertilizer solution. Quantity and quality of pig manure and the end products were calculated by the known methods. Experimental studies were performed to compare the results. Samples were analyzed in the analytical laboratory of Institute for Engineering and Environmental Problems in Agricultural Production in 2022. Three replications were carried out for each sample. The experimental data were statistically analysed in MS Excel.
Results. Quantitative and qualitative characteristics of pig manure, its solid and liquid fractions, and end products were calculated. The difference between the calculated and actual values does not exceed 10.2% that indicates the reliability of calculations.
Discussion and Conclusion. The introduction of a new technology at the pig-breeding complex has reduced atmospheric emissions by 10% due to the nitrogen conservation, has reduced operating costs for transporting organic fertilizer by 47% due to the concentration of nutrients in a smaller volume and has improved soil fertility through fertilizer irrigation.

Published: June 2023

Introduction. Under conditions of high demand for rubber products, continuous modernization of technological processes of continuous production is carried out. One of the tools to control the physical and chemical parameters of the resulting product is the technology of multipoint feeding of controlling impurities that can significantly affect the molecular characteristics of polymers. However, it is difficult to experimentally select the technology of multipoint feeding of controlling impurities to achieve the given molecular characteristics of polymers.
Aim of the Article. To create a methodology that allows using the tools of model system description to carry out directed regulation and construction of the technological process to achieve a given molecular weight distribution.
Materials and Methods. For more accurate mathematical modeling of polymer synthesis processes, two approaches to the model description of the system under study are considered: 1) Kinetic approach. In this case, the developed algorithm is based on the method of moments in combination with numerical methods for solving systems of ordinary differential equations that characterize the change in the material balance for each reaction component. When describing large-tonnage production, a modular principle is proposed, according to which the kinetics model is supplemented by hydrodynamic regularities that depend on the reactor type. 2) Statistical approach (Monte Carlo method). The algorithm for implementing the statistical approach is based on the probabilistic nature of elementary reactions. To describe the process in the reactor cascade, a systematic approach to the organization of calculations is proposed.
Results. Using kinetic and statistical approaches new dependences of conversion and characteristic viscosity on polymerizer number were obtained, which showed satisfactory agreement with the values of the experimental results. Comparative analysis of calculated molecular-mass distribution curves of obtained product was carried out. The analysis confirms the significant influence of different modes of regulator feeding on molecular characteristics of polymer.
Discussion and Conclusion. The analysis of the molecular chain structure of the copolymerization product under conditions of adding the third control point characterizes the decrease in rigidity and increase in elasticity of the resulting product, and the created digital evaluation tools allow by means of computational experiments to select optimal parameters of the regulator feeding in order to obtain polymers with a given molecular mass.
Ensino de Eletromagnetismo

Published: June 2023

O estudo do Eletromagnetismo exige um grau de abstração para a compreensão de alguns conceitos, como a capacidade de interpretar a linguagem própria da Física repleta de signos específicos e sistematizar esses símbolos em operações de cálculo ou em explicações conceituais. A dificuldade de visualização geralmente motiva certo desinteresse de grande parte dos alunos. Entretanto, o interesse discente em aprender é um dos fatores para uma aprendizagem significativa, bem como para uma formação mais crítica. Nesse contexto, é importante que se criem condições para instigar a curiosidade dos estudantes, buscando novos caminhos que estimulem a elaboração de hipóteses, a pesquisa, a solução de problemas contextualizados dentro e fora do ambiente escolar. Neste trabalho, é apresentada uma proposta didática baseada no modelo híbrido Rotação por Estações para o ensino de conceitos de Eletromagnetismo em aulas de Física, para fins de facilitação da aprendizagem. Tal proposta desenvolve-se em oito encontros com dois tempos de aula cada, tendo como público-alvo alunos da terceira série do Ensino Médio. Espera-se que seja um instrumento que colabore com a prática docente para o desenvolvimento de aulas diferenciadas, com a utilização de tecnologia, experimentos, entre outros recursos didáticos e que possibilite uma participação ativa e crítica dos alunos com autonomia no processo de aprendizagem.

What Is Not, but Might Be: Disnarration as Narrative Device in the Hebrew Bible
Authors: D’Amico Davide
Published: June 2023

This article investigates the use of disnarration in the biblical text as a narrative device to create cooperation between text and reader. Conceptualized by Gerard Prince in the late 1980s, disnarration refers to the technique of narratively explicating plot outcomes that are not realized in the actual flow of the story. This mechanism leads to several consequences that stimulate the reader’s inference by producing a mimetic effect and contributing mainly to two functions. The first is to contribute to the creation of a narrative world that simulates the contingency of the real world; the second is to provide the reader with elements essential to the characterization of the characters involved in the disnarration process. Through some examples, it will be seen how biblical authors use disnarration and how this device contributes to creating a more complex and deeper narrative.
The Jewish Pig Prohibition from Leviticus to the Maccabees
Authors: Rhyder Julia
Published: June 2023

Pig avoidance is among the most famous and well studied of the customs described in the Hebrew Bible. Commonly the ban on consuming pork has been considered evidence of the importance of dietary prohibitions in establishing boundaries between Israel and neighboring groups. I argue, however, that differentiation from other ethnicities by means of diet was not the only function that the pig prohibition served in ancient Israel. In fact, the relevant biblical texts are as much, if not more, concerned with employing the pig prohibition as a device by which cultic norms as well as dietary customs within the Israelite community were standardized. With the accounts of the Maccabean rebellion in the second century BCE, the pig assumes a greater significance in identity formation, but even in these traditions, the relationship between pig avoidance and ethnic boundaries is more complex than is often assumed. Detailed analysis of the references to the pig in Lev 11, Deut 14, Isa 56–66, and 1 and 2 Maccabees, along with the study of archaeological evidence and comparative materials from the ancient Near East and ancient Mediterranean more broadly, reveals the multiplicity of factors that shaped the emergence of pig avoidance as a central custom in ancient Judaism.
Prophetic Validation and the Nonregnal Dates in the Superscriptions to Jeremiah and Amos
Authors: MacGillivray Ian M. A.
Published: June 2023

In superscriptions to the biblical prophetic books, dates are usually expressed in terms of the reigns of kings. In the headings to Amos and Jeremiah, however, the standard regnal chronology is augmented by a “nonregnal date” that does not directly refer to a monarch. Amos’s prophecies are set “two years before the earthquake” (Amos 1:1), while Jeremiah’s career ends with “the exiling of Jerusalem in the fifth month” (Jer 1:3). In this article, I examine both of these nonregnal dates and conclude that they serve similar rhetorical purposes in their respective books. Each reference anticipates central themes of divine judgment that are developed across the rest of the book, while also corroborating an important prediction that reinforces the authority of the titular prophet. The nonregnal dates thus help to show how the social processes of “prophetic validation” continued to operate in the literary production of prophetic books. The uniqueness of these dates among the Latter Prophets may be related to the unusually detailed accounts of prophetic conflict found in Amos and, especially, Jeremiah.

Abstract: According to the World Health Organization (WHO), 1.6 million deaths and 10.6 million cases of tuberculosis (TB) were reported worldwide in 2021. If treated opportunely with the recommended therapy, 85% of patients with TB are healed. The occurrence of death from TB without prior notification of the disease indicates failure in the timely access to this effective treatment. Therefore, this study aimed to identify TB cases with post-mortem notification in Brazil. This is a nested case-control study using a cohort of new TB cases reported to the Braziliam Information System for Notificable Diseases (SINAN). This study analyzed the following variables: selected characteristics of the individual (gender, age, race/color, education), the municipality (Municipality Human Development Index - M-HDI, poverty rate, size, region, and municipality), health services, and underlying or associated cause of death. Logistic regression was estimated using a hierarchical analysis model. People with TB aged 60 years or older (OR = 1.43), with low educational level (OR = 1.67), and with malnutrition (OR = 5.54), living in municipalities with low M-HDI and medium population size (OR = 1.26), located in the North Region of Brazil (OR = 2.42) had a higher chance of post-mortem notification. Protective factors were HIV-TB coinfection (OR = 0.75), malignant neoplasms (OR = 0.62), and living in cities with broad primary care coverage (OR = 0.79). Vulnerable populations should be prioritized in order to address the obstacles to the access to TB diagnosis and treatment in Brazil.

ABSTRACT: This retrospective study evaluated the impact of the clinical presentation of pyometra on the morbidity and mortality of the affected bitches. The medical records of 47 bitches surgically treated for pyometra between May and December 2017 were evaluated. The admission data were analyzed to classify the animals according to the clinical presentation of pyometra, presence of systemic inflammatory response syndrome (SIRS) and organic dysfunctions (cardiovascular, neurological, renal, and hemostatic). The outcomes were recorded for up to 14 days. The overall mortality rate was 13%. Open and closed pyometra were identified in 62% (n= 29) and 38% (n= 18) of the cases, respectively. The SIRS was present in 44 (94%) bitches, and 27 (57%) had at least one organ dysfunction. The most prevalent dysfunction was hemostatic, followed by neurological, cardiovascular, and renal dysfunction. The clinical presentation of pyometra and the presence of SIRS did not correlate with each other, or with the presence of organ dysfunction and mortality. However, cumulative organ dysfunction (r=0.532, P=<0.001) and the presence of neurological (r= -0.371; P=0.012) and renal dysfunction (r=0.303; P=0.041) were correlated with mortality. Thus, the identification of organ dysfunction through physical examination and routine laboratory analysis proved to be more effective in identifying and predicting the critically ill patients than the SIRS criteria or clinical presentation of the disease.

ABSTRACT: In integrated crop-livestock systems, overseeding annual summer pastures over grain crops can reduce forage shortages in autumn without altering grain production. This study evaluated the influence of pearl millet (Pennisetumglaucum L.) and sudangrass (Sorghum Sudanese) overseeded on a soybean (Glycine Max) crop or no-tillage seeding after soybean harvest on productive aspects of pasture. The experimental design was a randomized block with treatments in a 2 × 2 factorial arrangement (pearl millet or sudangrass, overseeding in the full seed stage (R6) of soybean crops or seeding them in a no-tillage system after soybean harvest) in two agricultural years. Pasture height, plant stand, tiller density, and forage production were higher in the first crop year. The overseeding strategy resulted in higher pasture height and foraged production in the first crop year and higher pasture utilization for the next two crop years. Under the no-tillage strategy, the plants stand more elevated in the first crop year, resulting in a higher tiller density in the second crop year. Pasture height, utilization period, and forage production did not differ among the forage species. Pearl millet had a more elevated plant stand, while sudangrass had a higher tiller density. Annual summer pasture overseeding of soybean crops increases the pasture utilization period and forage production in autumn.
