Authors: Kuznetsova I. A. , Maksimov I. I.
Published: April 2021

The article presents the results of the studies for the porphyry copper ores of the Tominsky deposit conducted to develop the respective processing technology. These process studies had been carried out since 2011 jointly by the TOMS Institute, Outotec, and JSC Mekhanobr Engineering. The experiments were carried out in 2017 at the laboratory of Mekhanobr Engineering using an ore charge from the Tominsky deposit and its Kalinovsky area with the percentage ratio of 75:25, copper content of 0.37 wt%, gold content of 0.09 g/t, and silver content of 0.89 g/t. The closed-cycle experiments yielded copper concentrates containing 20.7 wt% of copper, 3.95 g/t of gold, and 39.9 g/t of silver, with the recoveries of 90.27, 72.71 and 72.45 %, respectively. According to the results of the studies, the following technology was recommended for the design of the concentrator for the ores of the Tominsky deposit: semi-autogenous grinding and ball milling of the ore to 85 % passing –0.071 mm, rougher and scavenger flotation, rougher concentrate regrinding to 80 % passing –0.035 mm and two cleaner flotation stages for the rougher concentrate to obtain grade KM-5 copper concentrate with the mass fraction of copper of 20 % and copper recovery of 85 %. The concentrator of JSC Tominsky GOK, designed by JSC Mekhanobr Engineering, was put into pilot operation in 2020 and has reached its design performance.

Published: April 2021

The article presents the results of an experimental study to establish the leaching indicators for limestone-kaolin cakes conducted using soda solutions with various process parameters. The experiments use the mathematical planning method that allows assessing the significance of various cake leaching parameters with the minimum number of experiments. It is shown that the temperature and concentration of the soda solution have a significant effect on the aluminum oxide recovery, with the highest recovery of 79.5 % within the selected factor variation intervals achieved at the process temperature of 50 °C, the soda solution concentration of 100 g/l, the liquid/solid ratio in the slurry of 7, and the leaching time of 25 minutes. Further studies using the coordinate-wise optimization method allowed establishing the leaching process parameters that ensure the aluminum oxide recovery of up to 85.2 %. At the same time, the paper shows a significant effect of the process temperature and time on the depth of secondary interactions leading to the deposition of aluminum oxide and requiring additional systemic studies. The established chemical and material composition of the sludge suggests that it may be effectively used as a component in raw Portland cement mixes, as well as a raw material for the regeneration and recycling of the lime component, which would reduce the consumption of natural carbonate raw materials and cut the emissions of greenhouse gases into the atmosphere. The research was carried out with the use of the laboratory equipment of the Scientific and Educational Center for Shared Use of the St. Petersburg Mining University. The work was carried out with the financial support of the Russian Science Foundation under the Agreement No. 18-19-00577 of April 26 2018 of grant for fundamental scientific research and exploratory scientific research.
China’s aluminium sector and prospects of global aluminium industry
Authors: Korneev S. I.
Published: April 2021

Using statistical data, this paper analyzes the evolution, current status and prospects of China’s aluminium industry: sufficiency of raw materials, bauxite mining, alumina production, capacity utilization, primary aluminium output, technological development. The analysis confirms that China will maintain its leading position at the global aluminium market in the long term. Thus, China will remain the world’s biggest importer of bauxites and alumina, the leading producer of alumina and primary aluminium, a big exporter of semi-finished products and aluminium compounds with a high added value. The growth of the country’s aluminium sector is a typical example of China’s global economic dominance policy — i. e. imports of raw materials, rising production and exports of final products, which are sweeping the national and international markets thanks to breakthrough technology and competitive prices. Being the key player at the global market for non-ferrous metals (primarily, aluminium), China, on one hand, generates an initial demand for them by using them in manufacturing and, on the other hand, the country is interested in low and stable prices. The main advantages of China’s aluminium industry include its large scale, low energy consumption, the capacity of the steadily growing internal market, available production facilities with a low wear level, a developed transport infrastructure and port facilities, an aggressive merge policy exercised at both the national and international markets, the government’s flexible currency policy, quick decision making, a high economic mobilization discipline. In the long run, only primary aluminium producers of comparable size and technology status (both the existing and the projected ones) will be able to survive the competition with their Chinese peers.

Published: April 2021

The work is aimed at the oxidative processes occurring in the metallic structures of the universal refrigerators “UKHB 3/30” used to transport and cool calcined coke. The temperature of the coke entering the device reaches 1320 oC. As it moves along the device, chemical and thermal effects occur on unprotected metallic structures with the formation of erosion centers and through damage to the shells. The service life of refrigerators hot-cut metallic structures made of A284 Grade B (ASTM) is 1 year, which determines its repairs frequency. Experiments on the oxidative processes in real conditions of operation of refrigerators were conducted for samples made of carbon steel of the A284 Grade B (ASTM) brand and heat-resistant high-alloy steel AISI 301. Changes in the chemical composition and physical parameters were determined in the samples. The thermogravimetric method for estimating the corrosion kinetics based on the sample mass loss, spectrometric study of metal samples, and classical chemical “wet” analysis were used. According to the results, the degree of corrosion damage of samples after 1,5 hours is estimated. The kinetics of corrosion has been studied. The mechanism of decarburization of the surface layer in A284 Grade B (ASTM) steel and the accompanying deterioration of the metal mechanical properties are described. An economic analysis of the feasibility of using AISI 301 steel to increase the service life of refrigerators was carried out.

Published: April 2021

Medical doctors of today are challenged with increasingly large volumes of high-dimensional, heterogeneous and unstructured data from various sources that pose significant challenges for manual analysis. However, this unstructured data is mainly vital for decision making but there exists shortage of intelligent tools to extract the hidden knowledge. In view of these facts, application of machine learning methods in healthcare is a growing phenomenon. This paper explores machine learning approaches for interpreting large quantities of continuously acquired, multivariate patient based laboratory data, in intensive care unit (ICU) settings. The research hypothesizes that principal component analysis (PCA) can be able to capture the changes in the outcomes of applying medical interventions. We adopted PCA as a main method, to observe and capture the daily changes for intensive care unit patients. The approach will be able to inform the physicians, which laboratory tests are exhibiting variances after an intervention, and their associated epiphenomenon. This can be used as a clue to make decisions on which treatment or diagnosis to apply further. Experimental analysis results indicate that PCA was able to capture patient progression in terms of variances and permutation tests for the validity and stability of the model exhibits an acceptable significance level with a p-value of 0.001. Results showed that the approach provides promising results for interpreting large quantities of patient data for establishing a cause-effect relationship from medical interventions and be used as an early warning system. The study retrospectively demonstrated the capability of PCA to monitor and provide an alert to the clinicians about the patient’s changing conditions, thereby providing opportunities for timely interventions. If coupled with other machine learning models, the approach can also be able to support clinical decision making and enable an effective patient tailored care for better health outcomes.
Automatic Positioning of Mobile Users via GSM Signal Measurements
Authors: DEMİR Ercan , ÖZTEKİN Abdulkerim
Published: April 2021

Today the need for mobile communication systems and the high increase in the number of users have also made the development of new generation mobile applications indispensable. Obtaining location information has been one of the most interesting and significant areas of improvement. The purpose of the services used to determine the location is generally to obtain the information of the users such as approximate location, speed and time. The GPS system is the most preferred and globally accurate positioning system among global positioning systems. However, in addition to requiring a high installation cost of this system, it is one of the biggest constraints that galactic and meteorological factors, high buildings and other physical obstacles, and especially closed areas can lead to serious signal weaknesses and losses which may cause the system to be out of service. Considering these issues, it is seen that there is an urgent need for positioning systems that will be alternative and complementary to global positioning systems. The cellular network is widely used by almost everyone and its coverage area is increasing day by day. The employed data sets were created by recording the received signal strength (RSS), location information of the GSM base station and the user measured in indoor and outdoor areas through a mobile application we have developed in the Android Studio environment for mobile phones. The network has been trained by machine learning algorithms; extreme learning machine (ELM), generalized regression neural network (GRNN) and k nearest neighborhood (kNN). In the tests conducted with indoor, outdoor and combined data sets, it has been observed that the proposed positioning system works well with distance error rates below a meter (m) at the minimum, and between 76-216 m on average.

Authors: Sharipova Elena V. , Babachenko Irina V. , Orlova Elizaveta D.
Published: April 2021

Objective: to study the clinical features of metapneumovirus infection in children of different ages in a hospital.

Materials and methods. A retrospective analysis of medical records of 142 patients aged 1 month to 14 years inclusive who were hospitalized in the period from January 2012 to April 2019. Metapneumovirus infection was confirmed by hMPV nucleic acid isolation by PCR in nasopharyngeal smears.

Results. Metapneumovirus infection is detected among hospitalized children with acute respiratory viral infections in 4,4% of cases. In the age structure, 72,2% are children under 4 years old, and the maximum incidence rate is among children aged 3 years of life. The leading clinical symptoms are cough in 93,0% of cases and rhinitis in 96,5% of cases.In 88,2% of children, the disease proceeds with an increase in temperature 38 C, including in 34,6% 39,5 C and above. Symptoms of gastrointestinal dysfunction in the form of vomiting and diarrhea develop in 26,1% and 22,5% of children, respectively. 78,2% of patients requiring hospitalization suffer hMPV infection with damage to the lower respiratory tract, including in the form of bronchitis in 85,6% of cases and pneumonia in 14,4% of cases. The disease is complicated by the development of bronchial obstructive syndrome in 38,7% and acute respiratory failure in 22,3% of cases. ARF and BOS are significantly more likely to develop in children of the first 3 years of life 71,0% versus 29,0% in children of the older age group (p = 0.038) and 69,8% against 30,2% (p = 0.007), respectively. In a clinical blood test for hMPV infection, leukopenia and leukocytosis are detected only in 3,5% and 12,7% of cases, respectively, as well as an increase in ESR in 23,9% of children. The level of CRP in the 93,0% of children was less than 20 mg/l.

Conclusions. Virological confirmation of metapneumovirus infection in hospitalized children with lower respiratory tract infections contributes to the formation of an adequate therapeutic tactic.
Niemann–Pick disease in a child with congenital cytomegalovirus infection
Authors: Bem Elena V. , Fedorova Larisa A. , Sajkova Maria Yu. , Reutskaia Olga G.
Published: April 2021

In this publication, we present own clinical observation demonstrating the early diagnosis of NiemannPick disease, type C (NPС) in a child with congenital cytomegalovirus infection (сCMV). NiemannPick disease is a rare orphan inherited disease with an autosomal recessive type of inheritance that belongs to lysosomal accumulation diseases. There are 4 clinical phenotypes of NiemannPick disease (A, B, C, D), among which types A and B are associated with a mutation of the lysosomal sphingomyelinase (SMPD1) gene, and types C and D are associated with mutations in the NPC1 or NPC2 genes responsible for intracellular transport of cholesterol and lipids. The disease is a form of glycosphingolipidosis, which is accompanied by progressive degenerative processes in the target organs. The incidence of NPС is approximately 1 case per 100,000 live births. During the newborn period, NPС may occur under the guise of the other inherited or acquired diseases, and sometimes be combined with them. In particular, the manifest form of neonatal cytomegalovirus infection has similar target organs for damage to the NPС: the liver, the spleen, and the Central nervous system. The multi-system nature of clinical manifestations requires a differential diagnosis and clarification as early as possible. The polymorphism of clinical manifestations and the lack of diagnostic tests for mass screening make it is difficult to diagnose the disease. In the given clinical case, the diagnosis of NPС in a child with congenital cytomegаlovirus infection was established using DNA diagnostics of NPC1 gene mutation at the age of 2.5 months of life, which allowed determining the long-term management and medical observation.

ResumenEl objetivo de este trabajo fue evaluar el conocimiento común y especializado del contenido de los futuros profesores españoles de bachillerato sobre el intervalo de confianza. Para lograr tal fin se propuso a un grupo de 73 futuros profesores un problema abierto sobre intervalo de confianza, similar a los propuestos en cursos anteriores a los estudiantes de Bachillerato en las pruebas de acceso a la universidad. Además, se les preguntó cómo explicarían a un estudiante el significado del intervalo de confianza y sus propiedades. Utilizando una metodología cualitativa de análisis de contenido, se estudia el planteamiento, cálculo, interpretación y definición del intervalo y las propiedades que recuerdan. Aunque la mayor parte de los participantes en el estudio plantea y calcula correctamente el intervalo, sólo el 28,8% de los futuros profesores lo interpreta correctamente. Se encuentran interpretaciones deterministas o propias a la metodología bayesiana, similares a las descritas en investigaciones con estudiantes. Otros o no proporcionan una interpretación. Pocos participantes fueron capaces de definir correctamente el intervalo de confianza cuando se les pide explicar a un estudiante su significado y recuerdan pocas propiedades del mismo. Se concluye la necesidad de reforzar el conocimiento del contenido sobre intervalo de confianza en estos futuros profesores.

AbstractThe aim of this research was to assess prospective high school teachers’ common and specialized content knowledge of confidence intervals. To achieve this aim, we proposed to 73 prospective teachers an open problem similar to those proposed to high school students in the previous years at the entrance to university tests. Besides, participants were asked to describe how they would explain the concept and its properties to a student. Using the qualitative methodology of content analysis we study the setting, computation, interpretation and definition of confidence interval and its properties. Although most participants correctly set and computed the confidence interval, only 28.8% of them made a correct interpretation of the same. Deterministic and Bayesian interpretations, similar to those described in previous research with students arose or there was no interpretation. Few participants defined correctly the interval when asked how they would explain the topic to a student; additionally, only a few properties of the interval were remembered. We conclude the need to reinforce the content knowledge of confidence intervals in prospective teachers.

ResumoO livro didático é uma das principais fontes de consulta dos professores no ensino de estatística. Esse artigo analisa atividades envolvendo tabelas apresentadas nos livros didáticos de Matemática, dos anos iniciais do Ensino Fundamental do Brasil e do Quebec/CA. Nossas análises se fundamentaram em seis categorias: tipo de representação (quadro, banco de dados ou tabela); função da tabela; habilidade explorada; tipo de tabela (simples ou dupla entrada); tipo de variável; representação dos elementos fundamentais da tabela. Os resultados revelam que, em todos os anos de escolarização, podemos encontrar os três tipos de representação, sendo a maior frequência de tabelas em ambos os lugares de publicação. Além disso, a maioria delas é utilizada como objeto de estudo, indicando uma mudança recente de foco nos livros brasileiros, que priorizavam atividades na quais as tabelas eram pretexto para outros conceitos serem abordados. Observamos, entretanto, uma ênfase em interpretar e completar tabelas já estruturadas. Infelizmente, muitas tabelas não apresentam a fonte, principalmente nos livros do Quebec. A ausência de contextos reais e significativos não contribui efetivamente para a aprendizagem Estatística pelos alunos.

AbstractTextbooks are one of the main sources of consultation for teaching statistics. This article analyzes activities involving tables presented in Primary School Mathematics textbooks from Brazil and from Quebec - CA. Our analysis were based on six categories: type of representation (rectangular configuration, database or table); table function; explored skill; table type (single or double entry); type of variable; representation of the fundamental elements of the table. The results show that in all years of schooling we can find the three types of representation, with the highest frequency of tables in both places of publication. Most of them are used as an object of study, indicating a recent change of focus in Brazilian books that prioritized activities in which tables were a pretext for other concepts to be addressed. However, we still observe an emphasis on interpreting and completing tables already structured. Unfortunately, many tables do not present their source, especially in Quebec textbooks. The absence of real data and significant contexts effectively does not contribute to the students' significant learning of Statistics.

Resume:The present article arose from the interest in games that involved Mathematics during the school stage in a project called Young Mathematicians, whose purpose was the use of games aimed at learning Mathematics. In this study, we chose to investigate the use of matchstick as a support for learning Probability content in the 5th grade of elementary school I. We aimed to analyze the influence of matchstick on the understanding of 5th grade students on the content of Probability, seeking to identify its influence, particularly with regard to randomness, sample space and probabilistic calculation. A pre-test was conducted with 18 5th graders to analyze the students' previous knowledge and after the familiarization of the game we performed the post-test to know the influence of the game. It is concluded that in general the game can be an instrument for understanding the content of Probability in approaches to probabilistic reasoning, sample space identification and random event estimates.

Classifying the Epicurean Goods
Authors: Gillham Alex R
Published: April 2021

Scholars have paid little attention to the classifications among goods that Epicureans posit. This paper remedies that deficiency. I argue for three claims. First, if we take instrumental goods to be those that are a means or causally lead to the intrinsic good and we take constitutive goods to be those that are part of or amount to the intrinsic good, then the Epicureans probably took reverence for a wise man and wisdom to be instrumental goods but self-sufficiency and phronesis to be constitutive goods. Second, Epicurean personal goods are those that produce eudaimonia but are firmly up to us to achieve rather than owing to chance. Third, Epicurean immortal goods are those that bring about divinely resilient tranquility for those who cultivate them. I then show how positing these classifications enables the Epicureans to claim that godlike happiness is achievable through our own efforts no matter the external circumstances.
What does Divination Mean for Plato’s Socrates? On the Relationship between Being and the Good
Authors: Zhang Huaiyuan
Published: April 2021

Has philosophy ever completed a transition from divine revelation to rational reflection? Has it been Plato’s goal? In this paper I will establish and examine a parallel between divination and philosophy embodied in Plato’s Socrates. I will cite instances from both directions to analyze Plato’s indecision concerning a philosophical treatment of divination: On the one hand, Plato renovates the cultural stock of divination to supplement the rational process of Socratic dialectics. In particular, when he makes a proposal not as a proven proposition, but as the starting point of discussion, Socrates frequently helps himself to divinatory language. On the other hand, Plato does not seem to abandon the nondiscursive elements in his narrative, especially since the vision of the ultimate objective of the Platonic-Socratic project, i.e. the Good, requires a resort to divination. The indecision is reflected in the textual ambivalence as to whether the being of the Good transcends other forms or is on a par with other forms as the noblest form. Based on the correlation between the power of knowledge and the object of knowledge, I will argue that the epistemic entanglement of divination with reason in Plato’s approach corresponds to the ambiguous relationship between being and the Good in Plato’s ethically imbued metaphysical scheme. Since Plato presents Socrates as a seer in the aforementioned occasions, I will further suggest that Plato presents himself as a collector of oracles by preserving Socratic’s teaching in writing, whose ultimate meanings are open to interpretation and debate.
Aristóteles Contra o Bem dos Economistas
Authors: Maximo Mário
Published: April 2021

Despite its origins within moral philosophy, economists think their science has nothing to do with the good. They appeal to some kind of Hume’s guillotine that divides the descriptive and the normative. With that in hand, they affirm the solely descriptive aspect of their discipline. I argue this is not the case. Economists have, as they need to, an all encompassing notion of the good. I suggest going back to Aristotelian arguments to show the shortcomings of this good of economists. Aristotle is helpful because of his analysis of chrematistics and the real function of money. Hence, the loosely utilitarian good of the economists is confronted with a robust sense of the good and the human form. The capability approach is the first to identify these weak points on economic theory and to propose a sort of Aristotelian comeback. However, I claim the capabilities approach itself doesn’t follow the Aristotelian arguments used to attack economists to its necessary conclusion. Therefore, I suggest that the recent advances in neo-Aristotelian ethical naturalism can be used to reformulate economics by dispossessing economists of their sumo bonnun.
A Insuficiência das Leis: uma Reflexão sobre o Pensamento de Antifonte
Authors: Azevedo Cristiane A. de
Published: April 2021

In the 5th century BC, in Athens, Antiphon reflects on the relationship between physis and nómos in a way quite different from most sophists. Indeed, one of the particularities of sophist thought is to minimize physis so that thinking focus itself on nómos, on what man can, through thinking and debate, establish in regard to the common good and justice in the pólis. However, Antiphon takes up this relationship between nature and law to direct it to another path. In an unusual way for a sophist, we see physis being emphasized at the expense of nómos. The comparison between the two concepts also serves as a backdrop for harsh criticisms of justice and laws. The objective of this article is, through the criticisms Antiphon makes to the system of the laws of the pólis, to think about the relationship established by the sophist between physis and nómos in order to find out if there is a new understanding of these concepts and to reflect the reason that led Antiphon to revisit them.
El logos propio y el problema de la verdad en Antístenes
Authors: Chame Santiago
Published: April 2021

In this paper, I examine Antisthenes’s conception of truth in order to better understand the relation between ontology and language in his thought. I intend to show that it presents a sharp contrast to Plato’s account of the problem of truth, which relies on an affirmative conception of ontology that involves both the concepts of correspondence and of predicative attribution. While for both philosophers the problem of truth is central, Antisthenes develops a peculiar perspective that subverts Plato’s attempt to sort, through dialectics, the interferences that permeate language, in order to gain access to an essential instance that warrants a truthful discourse. For Antisthenes, truth cannot be understood in terms of correspondence, since, properly speaking, there are only true propositions.

The aim of the study is to analyze the income and price impact in trade between China and Turkey. In addition, to trade with this country which has a strategic importance in Turkey's foreign trade, to discuss the possible impact on Turkey's trade deficit. In the study where Autoregressive Distributed Lag (ARDL) econometric time series method was preferred, quarterly data of 1998Q1-2018Q4 period was used. All of the data were used in the analysis with their logarithmic values. The unit root test results performed showed that some variables are stationary in level values, while others contain unit roots. However, it has been observed that when the first differences are taken, they all become stable. F statistics obtained as a result of cointegration tests performed for both models showed that there is a long run integration relationship between variables. The results of long run coefficients showed that the impact of income in Turkey's exports to China is strong, stastically significant and compatible with economic expectations. On the other hand, both of price and income effects at Turkey's imports from China has been seen strong, istastically significant and compatible with economic expectations.

: Vitamin D deficiency is a serious health problem and is widespread in individuals irrespective of age, gender, race and geography. Despite being studied so much its deficiency is still missed by clinicians. This study was done to find vitamin D status of patients attending DM WIMS, Wayanad, Kerala, irrespective of the department they attended.

A retrospective cross-sectional study was done and the data for 1 year was extracted from HIS (hospital information system) and reviewed. The subjects were divided into three groups: Group A: level <20 ng/ml (vitamin D deficient), Group B: level = 21-29 ng/mL (vitamin D insufficient) and Group C: level between 30-100 (vitamin D sufficient).

Out of total 498 subjects in our study, 27% were males and 73% were females. Vitamin D deficiency was seen in 57.4% males and 72.5% females. The most affected age groups were 20 -40 years (28.7%) and 41-60 years (28.3%).

In the present study vitamin D deficiency was found to be more in females compared to males. Also the most affected age groups were 20-40 years. Routine screening for vitamin deficiency and its supplementation starting at all ages should be recommended to improve vitamin D status.

Published: April 2021

As áreas naturais protegidas são reconhecidas como a melhor estratégia para a preservação dos recursos naturais e também para a manutenção dos processos ecológicos, capazes de gerar inúmeras contribuições à sociedade, dentre elas o bem-estar. A partir do aumento do turismo em Unidades de Conservação (UCs) e dos impactos negativos causados por esta atividade, tornou-se necessário um planejamento que ordene a visitação e promova a sustentabilidade do ecossistema, conciliando assim o desenvolvimento e a conservação do ambiente. Deste modo, os objetivos do estudo foram levantar e caracterizar diferentes metodologias de estimação da capacidade de visitação em UCs apresentadas pela literatura. Foram levantadas oito principais metodologias, Limits of Acceptable Change (LAC), Visitor Impact Management (VIM), Visitor Activity Management Process (VAMP), Método Cifuentes, Visitor Experience and Resource Protection (VERP), Tourism Optimization Management Model (TOMM), Sustainable Recreation and Tourism (SRT) e Rol de Oportunidades de Visitação em Unidades de Conservação (ROVUC). O SRT foi identificado, mas não discutido em função de carência de informações. Os resultados apontaram que não é possível apontar uma metodologia mais eficiente ou adequada, visto que a adoção e aplicação destas metodologias levam em conta as características do meio, como o contexto da localidade, o acesso às áreas de preservação, a caracterização das atividades desenvolvidas por visitantes, entre outros fatores. Entretanto, este estudo apresenta um orientativo a respeito das metodologias de visitação existentes e que podem ser adotadas em UCs.
What Does a Pandemic Sound Like? The Emergence of COVID Verbal Art
Authors: Pennesi Karen
Published: April 2021

In times of social upheaval, people create and engage with verbal art for entertainment and a feeling of connection. While millions of people were forced to stay home to reduce the spread of COVID‑19 from March to July 2020, verbal artists posted recorded performances online and viewers had more time than usual to watch and share them. COVID verbal art refers to songs, poems, and comedy skits that mention social and physical distancing, quarantine and isolation, hygiene and cleaning practices, everyday experiences during the pandemic, as well as social and political critiques of policies and practices that explicitly mention COVID‑19 or coronavirus. An examination of 227 verbal art performances posted on YouTube and TikTok provides an ethnographic record of how everyday life has changed over time during the COVID‑19 pandemic, and how the focus shifted from initial confusion to political critique.

Purpose: The purpose is to investigate the effect of cefazolin sodium on perioperative prophylactic anti-infection in patients undergoing gynecological surgery. Methods: 112 cases of gynecological surgery from January 2019 to April 2020 were divided into the control group and the observation group, with 56 cases in each group. They were given cefazolin sodium + metronidazole and cefazolin sodium monotherapy respectively. The perioperative white blood cells and the incidence of adverse reactions of the two groups were compared. Results: There was no difference in the normal rate of white blood cell count between the observation group and the control group (P > 0.05), and no adverse reaction in the observation group, which was significantly lower than 7.14% in the control group (P < 0.05). Conclusion: the use of cefazolin sodium in perioperative period of gynecological surgery can prevent infection, with advanced security, less adverse reactions and high value.

Objective: To study the value of microscrew implant anchorage in orthodontic treatment. Methods: A total of 80 cases received orthodontic treatment in recent two years were selected and divided into experimental group and control group based on their received orthodontic measures, each group contains 40 cases. The control group was treated with general orthodontic treatment plan, while the study group received microscrew implant anchorage for the treatment. The clinical conditions of the two groups were counted and observed. Results: After different treatments, the effect of the study group was significantly better than that of the control group. All the indicators (including the improvement of molar displacement, incisor inclination angle and incisor convex distance) were available. In addition, there are obvious differences between the two groups in the occurrence of adverse reactions including inflammatory reaction, soft tissue edema and discomfort. Conclusion: In oral clinic, microscrew implant anchorage can achieve ideal curative effect for those who need orthodontics. Besides, its safety is relatively high, which is worth popularizing widely.

Background: Testes, epididymis and accessory glands measurements should be mandatory as an imminent for male selection. This study aimed at defining the ultrasonographic characteristics and measurements of testes, epididymis and accessory glands at different growth stages in Chios rams. Methods: Sixteen rams were assigned by age class into: group A (pre-pubertal, n=3), group B (pubertal, n=5) and group C (mature, n=8). Scrotal circumference (SC) was measured using a tape. Scrotal contents were examined using a B-mode ultrasound. Testicular breadth (TB), thicknesses of tunica albuginea (TA) and mediastinum (MS) and the largest dimension of epididymal tail (EpT) were estimated. Trans-rectal ultrasound was carried out to estimate the echogenicity and diameter of bulbourethral gland (BUG), height of pars dessiminata of prostate (PDP) and maximum breadth of seminal gland (SG). Result: SC increased curvilinear with age. Testicular echogenicity increased with age. Thickness of TA did not differ with age. MS could not detect in pre-pubertal rams, reached maximum thickness with puberty and became relatively thinner by maturity. EpT evidently enlarged with puberty. BUG, PDP and SG exhibited moderate echogenicity. They reached their greatest size with sexual maturity. SC estimated by tape and TB estimated by US correlated with most of the ultrasonographic measurements of the epididymis and accessory glands.
