Published: June 2021

Hydrolysis of the lignocellulosic biomass results in the release of high-value chemicals that during industrial processing can be recovered with membrane technologies. To maintain an effective performance of the membranes used in the technological processing of biomass, their regular cleaning is essential. Although several guidelines may be found for membrane cleaning in the cases of organic fouling, the data for cleaning membranes fouled by hydrolyzed lignocellulosic biomass is limited. Current research is aimed to evaluate physical (air backpulse) and common cheap chemical membrane cleaning methods. The results showed that air backpulse alone had a minor (9%) effect on the membrane cleaning. The alternation of NaOH (1 %) solution with the NaClO (200 mg/L of Free chlorine) was the most effective approach for membrane cleaning. The cleaning effectiveness was 95.1 % for 50 nm membrane and 89 % for 200 nm membrane, indicating that membranes used for hydrolyzed lignocellulosic biomass filtration can be effectively cleaned using affordable and accessible chemicals.

Published: June 2021

The relevance of the study is associated with the formation of a complex of stress factors of the environment in relation to graduates of higher military educational institutions and lies in the need for a systematic solution to the problem of adaptation of medical officers to professional activities in the Arctic. The aim of the study is to develop promising directions for the prevention of diseases and increase the efficiency of medical officers on the basis of a systematic study of medical-geographical, military-professional and socio-psychological factors in the formation of stable adaptation in graduates of higher military educational institutions. An original questionnaire Adaptation has been developed, which allows assessing the impact of the complex impact of stress factors. A systematic approach has been applied to assess the contribution of medical-geographical, professional factors, as well as lifestyle. Based on the results of the regression analysis, prognostic models of the influence of factors on the psychophysiological indicators of health, as well as correlations between the three groups of factors and the adaptive capabilities of the organism of military personnel, were obtained. It is concluded that the adaptation of military personnel in the Arctic is more intense in comparison with the redeployment in the subtropics and temperate latitudes. Ensuring high performance of young officers requires the planning and implementation of preventive measures based on monitoring the medical and geographical situation, preliminary adaptation to upcoming service activities, the development of infrastructure for everyday life and recreation of the families of military personnel, scientific support for the problem of redeployment of troops, including the adaptation of young officers. Ensuring high efficiency of young officers requires planning and implementation of preventive measures based on monitoring the medical and geographical situation, preliminary adaptation to the upcoming service activities, development of the infrastructure of everyday life and recreation for families of military personnel, scientific support of the problem of redeployment of troops (1 table, bibliography: 11 refs).

AIM: revealing microstructural brain connectivity alterations in patients with paranoid schizophrenia.
MATERIALS AND METHODS: 25 patients diagnosed with paranoid schizophrenia were examined. The control group was 30 healthy people without neurological and somatic diseases. Studies were carried out on the Philips Ingenia magnetic resonance tomograph, with a magnetic field strength of 1.5 T using the DTI pulse sequence. Data processing was carried out using the tractographic module DSI Studio.
RESULTS: According to the group assessment of the obtained tractographic brain data, significant differences in microstructural connectivity in the group of patients with paranoid schizophrenia were detected. A pathological conglomerate of cortical-subcortical structure connectivity was found, different from the sets of normal connections in the control group, consisting of a cingulate gyrus, hippocampus and thalamus. Such a pathological control center is one of the possible tractographic patterns of schizophrenia. In our opinion, the pathological connectivity of the hippocampus and thalamus, as one of the main components of the limbic system of the brain, reduces the controlling emotional function of the cingulate cortex, the control center of this system. In this case, excessive connectivity of the hippocampus with the cingulate cortex may indicate an incorrect implementation of their interaction, which also affects the occurrence or progression of emotional-will disorders. The thalamus, being the center of transmission of sensory and motor information from the sensory organs, can transmit incorrect redundant data about what is happening around the body and participate in the formation of auditory and visual hallucinations. Also, the pathological work of the thalamus may be involved in the progression of autism. Thus, the patient is increasingly losing touch with reality, increasingly preferring unknowingly fantasy, erasing ties with reality. Data from one of the characteristics of the artiformal neural network the clustering coefficient were significantly increased in patients compared to the control group, which may indicate the presence of excess, abnormal microstructural connectivity in the network.
CONCLUSION: The study confirms the presence of microstructural and neural network changes in the hippocampus, thalamus, cingulate cortex and basal ganglia. These changes are peculiar tractographic semiotic signs of brain pathology in paranoid schizophrenia. This study is a step in the search for a tool to identify the features of neuroplasticity disorders in this disease and schizophrenia screening (2 figures, 3 tables, bibliography: 13 refs).

The COVID-19 pandemic affected the whole world, threatened individuals physically, mentally and
socially, and considerably transformed their lifestyles in varying ways. Considering the spread of the
disease and affected age groups, the struggle with COVID-19 should not be limited to the medical
aspect but should also be addressed socially. The present study attempted to reveal how the usage
of social media has been modified during the pandemic by drawing attention to the aspects of the
COVID-19 pandemic that affected social life. The general aim of the study is to examine the purposes
and motivations of the individuals’ social media usage during the pandemic with reference to Uses and
Gratification approach. The research was carried out with 12 university graduate female participants
over the age of 50, who were determined by snowball sampling method. The findings obtained in this
study showed that the participants increased their usage of social media during the pandemic compared
to their previous engamenents with social media. Moreover, some of the participants increased their
usage of social media to reach news about COVID-19 faster, which pointed out their motivation to use
social media for obtaining accurate information. Finally, the most important change in the participants’
usage of social media was about their Twitter engagements. The results show that covid-19 has changed
social media usage and also points to the power of social media.

To search for new targets of therapy, it is necessary to reconstruct the gene network of the disease, and identify the interaction of genes, proteins, and drug compounds. Using the online bioinformatics tools we have analyzed the current data set related to the metabolism of xenobiotics, mediated by the N-acetyltransferase 2 (NAT2) gene. The study of allelic polymorphism of the NAT2 gene has a prognostic value, allowing to determine the risk of a number of oncological diseases, the degree of increased risk due to smoking and exposure to chemical carcinogens, including drugs. The aim of this study was to determine the frequencies of two important “slow” variants of the NAT2 gene (NAT2*5, rs1801280 and NAT2*7, rs1799931), which significantly affected the rate of xenobiotic acetylation among the indigenous Nenets population of Northern Siberia. The obtained frequencies of polymorphic variants among the Nenets occupy an intermediate value between those for Europeans and Asians, which might indicate specific features of adaptation. We present a model of the distribution of two polymorphic variants of the NAT2 gene involved in the biotransformation of xenobiotics to study the characteristics of their metabolism in the indigenous inhabitants of Yamal.

Based on the prediction of biological activity spectra for several secondary metabolites of medicinal plants using the PASS computer program and validation in vitro of the predictions results the priority direction of the pharmaceutical composition Phytoladaptogene (PLA) development was determined. PLA is a complex of structurally diverse small organic compounds including biologically active substances of phytoadaptogenes (ginsenosides from Panax ginseng, rhodionin from Rhodiola rosea and others) compiled considering previously developed pharmaceutical compositions. Two variants of the pharmaceutical composition were studied: — the major and minor variants included 22 and 13 compounds, respectively. The probability of activity exceeds the probability of inactivity for 1400 out of 1945 pharmacological effects and mechanisms predicted by PASS for the major variant of PLA. The wide range of predicted activities is mainly due to the low structural similarity of constituent compounds. An in silico prediction indicates the possibilities of antitumor properties against bladder, stomach, colon, ovarian and cervical cancers both for minor and major PLA compositions. It was found that the highest probability values of activity were predicted for three mechanisms: apoptosis agonist, caspase-3 stimulant, and transcription factor NF-κB inhibitor. According to the PharmaExpert program they are associated with the antitumor effect against bladder cancer. Experimental validation was using the human bladder cancer cell line RT-112. The results of the MTT test have shown that the cytotoxicity of the major PLA variant is higher than that of the minor PLA variant. In vitro experiments performed using two methods (double staining with annexin V and propidium iodide and detection of active caspase-3 in cells) confirmed that the death of bladder cancer cells occurred via the apoptotic mechanism. The data obtained correspond to the results of the prediction and indicate advantages of the major PLA composition. Thus, PLA can become the basis for the development of a drug with the antitumor activity against bladder cancer. The antitumor activity predicted by PASS for other cancers may be the subject of further studies.

Published: June 2021

The internal transport system of the body, represented by Srotamsi has been given a place of fundamental importance in Ayurveda both health and disease. Srotas are described as channels through which oozing of the fluids takes place. There are 13 srotas as described by Acharya Charak and 11 pairs as per Acharya Sushruta. Both have described the Medovaha Srotas and the vitiation of which leads to diseases of which Sthaulyata (Obesity) is one. According to Acharya Sushruta, the concept of Prakriti (body constitution) of an individual is derived by the predominance of Doshas at the time of fertilization. The entire health of an individual depends upon the Prakriti and health of a person is being affected according to it.

The present study is being done to find out the basic concept of medovaha srotas described in Ayurveda whose vitiation is the cause of medovriddhi (overweight and obesity) and its relation with the prakriti.

It was a clinical study conducted on total 150 cases in State Ayurvedic College and Hospital, Lucknow. The main tools used to conduct this study were the B.M.I criteria recommended by W.H.O and proforma of Prakriti Parishan.

The vitiation of medovaha srotas affects all the prakriti person almost in same manner i.e., fat accumulate beneath the skinfold and thyroid hormones level has relation with overweight and obesity. However the number of kaphaja prakriti persons showed that these are more prone to develop Obesity/overweight as a result of Medovaha srotodusthi.

Published: June 2021

The acceptance of any vaccine relies on the belief and perception towards it. After a wait of almost 10 months, the COVID-19 vaccine is ready with the first phase in progress in India. The aim of this study is to assess the impact on the acceptance intentions of COVID-19 vaccine among the general population of India after the vaccine is inoculated to health care workers in the first phase. An empirical study was conducted by analyzing the data collected by a self-administered questionnaire. The various variables that were addressed were the socio-demographic variables, past behavior of participants towards such seasonal influenza vaccine, awareness about the vaccine and adoption intention post vaccination drive. Logistic regression was used to identify the association between various variables and the predicting variables for the vaccine acceptance. Majority of them were ready for the COVID-19 vaccine. However, there was a decline in the acceptance rate post vaccination drive. Age, Gender and Region were found as the major factors affecting this decision.

To analyse, 1. The shift in confidence level in COVID-19 vaccine; 2. The role of Social Influence (SI) towards COVID-19 vaccine; 3. The role of past behavior towards seasonal influenza vaccines (Swine Flu, Ebola or similar) in acceptance of COVID-19 vaccine; 4. The association bet ween awareness of the COVID-19 vaccine and rate of adoption.

: The study was conducted by analyzing the data collected by a self-administered questionnaire that was shared online across India in January 2021 – February 2021. The variables that were addressed through the questionnaire were the socio-demographic variables, past behavior of participants towards such seasonal influenza vaccine, awareness about the vaccine and adoption intention post vaccination drive. Associations between various variables were observed during analysis. Logistic regression was also used to identify the predicting variables for the vaccine acceptance. Statistical analysis used: Odds Ratio, p-value, logistic regression

Out of 456 respondents, 59.21% were ready to uptake the COVID-19 vaccination, whereas 16.67% respondents declined to take the vaccine. There were 24.12% respondents who were not sure about the acceptance of the vaccine. Younger age groups specifically male from Northern India were more likely to accept the vaccine.

The major findings of the study shows that after the start of implementation of COVID-19 vaccination drive, there is a drop in the number of people who are ready to take the vaccine as compared to the number before the arrival of the vaccine. This may lead to the conclusion that the faith of general people of India has declined in the COVID-19 vaccine post vaccination drive.

Ku nowemu rozumieniu stypendiów mszalnych

Pojęcie „stypendiów mszalnych” zostało utrwalone w długoletniej tradycji Kościoła. Ich uzasadnienie można znaleźć w liście apostolskim Firma in traditione oraz w Kodeksie Prawa Kanonicznego z 1983 r. Mimo to zrozumienie ich znaczenia nie jest jasne i często bywa mylone z kupowaniem sakramentów lub rodzajem opłaty za wykonaną usługę. Z historycznego punktu widzenia stypendium Mszy św. wywodzi się z procesji z darami podczas sprawowania Mszy św. To właśnie podczas offertorium uczestniczący w celebracji Eucharystii składali swoje dary. Niniejsze opracowanie analizuje koncepcję tzw. stypendiów mszalnych i ich ewoluującą formę w praktyce Kościoła. Autor zwraca uwagę na fakt, że ofiary składane z racji Mszy św. muszą być spójne z teologią sakramentu Eucharystii i jego ścisłego związku między celebransem a ludem wiernych. Ostatecznie ofiary te przyczyniają się do dobra Kościoła oraz uczestniczą w jego trosce o utrzymanie szafarzy i dzieł.
Sankcje ustanawiane przez Radę Bezpieczeństwa ONZ a państwa nieczłonkowskie ONZ

Published: June 2021

Celem niniejszego artykułu jest zbadanie, czy sankcje ustanawiane przez Radę Bezpieczeństwa ONZ (RB ONZ) wiążą nie tylko państwa członkowskie ONZ, ale również państwa, które nie są członkami Organizacji. Artykuł opiera się na tezie, że w Karcie NZ (KNZ) nie ma podstaw prawnych, które pozwalałyby RB ONZ na uchwalanie sankcji wobec państw nieczłonkowskich, jak również sankcje przyjmowane przez Radę nie są prawnie wiążące dla państw pozostających poza Organizacją. Udowodnienie tej tezy wymagać będzie w pierwszej kolejności krótkiego scharakteryzowania mechanizmu sankcji na gruncie Rozdziału VII KNZ. W drugiej kolejności zostanie przeanalizowana treść i znaczenie art. 2 ust. 6 KNZ. Po trzecie, zostaną omówione argumenty wskazywane w doktrynie i praktyce prawa międzynarodowego, przemawiające za związaniem państw nieczłonkowskich sankcjami RB ONZ. W końcu zostaną przedstawione przykłady relacji między państwami nieczłonkowskimi a Organizacją w zakresie realizacji sankcji ustanawianych przez RB ONZ.

Authors: Deneva Aneta , Narojczyk Sebastian
Published: June 2021

The purpose of this chapter is to present the traditional methods used in operational man-agement. The methods described include benchmarking, outsourcing, Just-In-Time, kaizen, Total Quality Management, MRP I, MRP II, and core competencies developed in various periods of the 20th century to improve the planning process and efficient management of the flow of resources, goods and information. Benchmarking consists of comparing the processes and practices used by one’s own enterprise with those used in enterprises considered to be the best in the analysed field. Outsourcing means separating from the organizational structure of the enterprise some functions performed by them independently and transferring them to other entities for execution. Just-In-Time is used to reduce work in progress and inventory levels in production and warehouse processes. Kaizen and TQM are based on the continuous diagnosis and improvement of all elements of the company. MRP methods are based on computer systems and clearly defined, inter alia, the volume of demand, order fulfilment time and provide other data relevant to the company’s logistics system and its operations. Core competencies are company-specific skills that are difficult to copy or win over to competitors. The authors focused primarily on the presentation of the main goals, principles of operation, as well as the advantages and disadvantages of the selected methods in operational management.

Published: June 2021

Climate change, resource depletion, technical progress, growing consumer awareness and changing requirements causes companies to look for new production methods. They may concern various areas of the company’s activity, starting from product design, procurement organization, optimization of production processes, control of manufactured products and services, through improvement of work organization and reduction of production costs, and ending with the implementation of modern solutions based on digital technologies. The purpose of implementing new production methods is to improve labour mobility, optimization of the use of raw materials and resources, costs reduction, increase efficiency, productivity, etc. In the literature, there are many different types of methods that can be used by modern enterprises. It is practically impossible to present all methods in this study. The authors focused on the presentation of selected methods, which are characterized on the one hand by innovation and, on the other hand, by the possibility of implementation. Particular attention should be paid to methods focused on environmental aspects. This group presents basic information on environment-conscious manufacturing (ECM), life-cycle assessment (LCA) and waste management and recycling. These methods allow to implement the concept of sustainable development and are directly related to the 17 goals set out in the 2030 Agenda for Sustainable Development and adopted by UN member states. In the group of methods related to next generation production management, the focus was on Matrix shop floor control and cooperative manufacturing. Of particular importance is cooperative management, because cooperation in practice is considered as a specific resource and one of the most important factors of a competitive position. The next group of methods concerned production planning and control. Drum Buffer Rope (DBR) and theory of constraints (TOC) were discussed as part of it. From the company’s point of view, methods related to manufacturing processes are very important, including group technology (GT) and cellular manufacturing (CM). Another group focused on commercial aspects, including demand chain management (DCM) and competitive intelligence (CI). The chapter also presents methods related to auxiliary software support, advanced organizational manufacturing and focused on product design. In the first case, Electronic Data Interchange (EDI) was discussed, in the second, virtual enterprises (VE) and World Class Manufacturing (WCM) were presented, and in the third, the assumptions concerning the Quality Function Deployment (QFD) and House of Quality (HOQ) method were shown. Additionally, Statistical Process Control (SPC) and Computer-Aided Process Planning (CAPP) are discussed within the framework of methods focused on cost and quality manufacturing.

The paper examines the microstructure and mechanical properties of experimental compositions of a heat-resistant cobalt superalloy, produced by the method of selective laser melting (SLM). Strengthening in the studied materials is achieved by the formation of a fine-celled structure of a solid solution based on cobalt and highly dispersed intermetallic and carbide phases. By the EMPA (electron micro probe analysis) method, the ratio of chemical elements in these phases was evaluated and their type was determined. It was estimated that the tantalum content determines the strength properties of the alloy. It was found that dispersed particles formed during the synthesis have a positive effect on the creep resistance at 800 °C temperature, whereas at 1100 °C temperature the destruction occurs along the boundaries of the persisted structure of synthesis, regardless of the alloying and morphology of structural components.

Tal visão, oferecida pelos livros didáticos, é o fator limitante mais importante para o domínio destas competências. Modelos tridimensionais de boa qualidade são de custo elevado. Materiais biológicos de procedência conhecida e ética também são infrequentes, sua preparação e conservação exigem mão de obra especializada, curadoria constante e ainda requerem substâncias químicas no seu preparo que são irritantes, tóxicas ou com potencial de abuso, e.g. formol, álcool, clorofórmio. A necessidade de aproximar o estudante do conteúdo ministrado em sala de aula enriquecendo a didática e melhorando o processo ensino-aprendizagem faz com que haja uma busca de novas maneiras e materiais que auxiliem o professor neste desenvolvimento. O protocolo de ação para a produção de material didático, para o ensino de Anatomia, fazendo uso de fatias semifinas de encéfalo de vertebrados, fixado e posteriormente incluídas em resina acrílica de poliéster facilita o contato real do estudante com o exposto teoricamente, desvinculando da necessidade de um laboratório de Ciências e Biologia, uma vez que a resina é um material leve, atóxico, de grande durabilidade e que pode ser levado para dentro da sala de aula. A escolha de peças da neuroanatomia (encéfalos) se mostra interessante devido a sua complexidade estrutural e de nomenclatura que, ao ser vista e manuseada, facilita ao estudante a correlação teórico-prática.
Clinical and microbiological characteristics of diabetic foot infection by carbapenem-resistant bacteria in a hospital in southern Brazil
Authors: Braun Stela , Silva Marcia
Published: June 2021

Carbapenem-resistant bacteria are a major cause of diabetic foot (DF) infection. They are resistant to almost all available antimicrobial agents and lead to increased hospital costs. The clinical and microbiological characteristics of DF infection due to these microorganisms and the association of DF with outcomes such as mortality and amputation are not yet well established. This was a retrospective cohort study involving 60 vascular surgery patients who were admitted to Nossa Senhora da Conceição Hospital due to DF infection caused by carbapenem-resistant bacteria and who underwent debridement or amputation, and a control group with 60 randomly selected patients. The analyzed parameters were mortality and amputation rates and patients’ epidemiological and microbiological profiles. A significant association was observed between bacterial resistance and previous amputation, previous hospitalizations, and DF ulcer classification into ischemic and neuroischemic; however, there were no differences in mortality and amputation rates between the groups, even after using the Charlson comorbidity index. Although DF infections by carbapenem-resistant bacteria were not statistically associated with worse outcomes, their study is important given that there are few therapeutic options for treating these specific infections.
Drenagem e a Urbanização – Estudo de caso dos impactos da urbanização no sistema de drenagem em uma cidade de pequeno porte
Authors: Cauduro Flávia , De Matos Henrique
Published: June 2021

O crescimento populacional e o processo de urbanização, sem planejamento em infraestrutura urbana, vem acompanhado de inúmeros problemas, principalmente no que se refere às instalações urbanas dos sistemas de água, esgotos sanitários e pluviais, e a inexistência de fiscalização que resulta na ocupação das áreas de risco. Dentre os sistemas instalados, o sistema de esgotamento pluvial compreende conjuntos de medidas que têm como objetivo minimizar os riscos e os prejuízos causados por inundações e possibilitar o desenvolvimento urbano de forma harmônica, articulada e sustentável. Em uma perspectiva mais moderna, os sistemas de drenagem devem ser vistos como um dos componentes do espaço urbano, uma vez que é impossível dissociá-lo da infraestrutura das cidades. O sistema deve ser projetado para compor a paisagem urbana e promover sua valorização de forma bem integrada ao urbanismo. O presente estudo tem objetivo de estudar o impacto do crescimento urbano no sistema de drenagem de uma cidade de pequeno porte do Estado de Santa Catarina. O objeto de estudo abrange a área central de uma municipalidade de 16.684 habitantes, fundada no ano de 1885. A área de estudo contempla uma região de ocupação mista, composta principalmente por residências horizontais e verticais, comércios de pequeno e médio, e está inserida na bacia hidrográfica do Rio Urussanga. O estudo foi realizado em três anos pré-definidos, 1999, 2009 e 2019. Com auxílio de imagens via satélite foi medido o desenvolvimento urbano nestes períodos com base nas taxas de uso e ocupação do solo correlacionadas com os Coeficientes de Escoamento Superficial. Foram então quantificados valores que permitem mensurar os impactos da urbanização num sistema de drenagem tradicional de modo a analisar os agentes de impacto e listar o desenvolvimento do sistema. O processo de urbanização estudado apresentou os resultados esperados, com o passar dos anos a área se desenvolve sem preocupação com as taxas ocupação do solo, apresentando uma redução de área verde na ordem de 36% ao longo dos anos. O sistema de drenagem é sobrecarregado devido a impermeabilização do solo e apresenta uma defasagem imediata a sua concepção, quando não analisado corretamente o cenário de pós urbanização.

A prática de atividade física é importante para pessoas idosas. É importante compreender os aspectos que podem influenciar o idoso na adesão e na manutenção do estilo de vida ativo e saudável. O objetivo deste estudo é investigar os fatores motivacionais de idosos que praticam atividades físicas regulamente. A coleta de dados foi realizada utilizando-se o IMPRAF-54 (Inventário de Motivação para Prática Regular de Atividades Físicas). A amostra foi composta por idosos com idade entre 60 e 79 anos (69,3±5,4), 27(54%) homens e 19(38%) mulheres. A maior motivação para atividade física nessa população foi relacionada a saúde (38,0±3,7) e o fator mais irrelevante foi a competitividade (9,3±3,0). Uma correlação binária entre os domínios do IMPRAF-54 realizada relacionou que o controle do estresse está positivamente associado à saúde, sociabilidade, estética e prazer. A busca por melhor saúde foi maior motivador para essa população. Algumas diferenças entre os sexos foram encontradas. A competição foi relevante em idosos com idades entre 60 e 69 anos do que idosos com idades entre 70 e 79 anos. Fator motivacional mais importante foi a saúde relacionada à prática de atividade física. A  competitividade foi negativamente relacionada à maioria dos domínios relacionados a IMPRAF-54.

Проведен анализ коллекции сортов гладиолуса гибридного.
Из 109 изученных 26 сортообразцов имели по 235 замещающих клубнелуковиц.
Из них более 50% сортов имели оранжево-лососевую и розово-малиновую окраску цветков, которая определяется антоциановыми пигментами.
Причем, у сортов с белой, зеленой, желтой и розовой окраской цветка число замещающих клубнелуковиц не превышало 2 шт.
Самый низкий коэффициент вегетативного размножения был у сортов с голубой окраской.
В этой группе не было сортов, способных образовывать из одной материнской клубнелуковицы несколько новых.
