Food Waste Loss Trend Index (FWLTI), A New Tool to Enable Management Decisions
Authors: Zachár János
Published: October 2021

The main purpose of this research is to work out a new, innovative tool to describe trends of food waste and loss (FWL) in the food industry. The result can help evaluate efforts for lowering wastes. FWL prevention recently gained much attention and priority among governments and international organizations as a major means to achieve global food security and sustainability; this led to the very ambitious UN goal SDG 12.3, which aims to halve global food losses by 2030. It is an ethical obligation to achieve SDGs by 2030. It is not declared in law and is not required for profitability in the food industry. A new tool is proposed to evaluate efforts to halve food losses in this article, which one may be used in leadership easily and effectively. At first, FWL definitions were analyzed to get a clear picture of the content of FWL data sourced from FAOSTAT and EUROSTAT. These definitions were compared with others from different sources. It is concluded that we have so many different definitions for FWL because of the difference in the purpose of data collecting. The most justified definition – often newly created – is used in each case. FWL data received from FAOSTAT and EUROSTAT in the period of 2010 − 2018 were compared to find the correlation. It is inverse and very weak, so they are not comparable; they must be evaluated separately. The trend of the FWL data is increasing and is not significant on level 95% in EUROSTAT, and decreasing and important on level 95% in FAOSTAT, from 2010 to 2018. FWL data from EUROSTAT are in moderate correlation with GDP and HDI. A new index, Food Waste Loss Trend Index (FWLTI), was created to evaluate FWL in EU member states and analyzed them with cluster analyses and scatterplots. There was no connection among the EU28 member states with FWLTI, so every member state is an individual case; there are no standard rules for FLW generation.

Published: October 2021

This study has been the focus of much investigation in the search for the association between transformational leadership behavior and job satisfaction among small businesses in the United States. Several attempts have been made to the importance that small businesses have on the economy, and small businesses constitute over half of all jobs. No known empirical research has focused on exploring the association between transformational leadership behavior and job satisfaction among small businesses in Virginia. The research is based on a theoretical framework such as self-determination theory. The investigation of association qualitative research study was undertaken to explore the potential relationship between transformational leadership behavior and job satisfaction among small businesses in the United States. Results showed the importance improvement both personal lives and the health of small businesses and the microeconomy of the United States. Employee satisfaction has been a topic of interest for scientists for many years and has roots in multiple psychological theories that served as a basis for understanding job satisfaction. When employees trust leadership, this can contribute many benefits to the business, such as an increased focus on being productive at work, commitment to the organization, intent to stay with the organization, and increased profitability. Small businesses are also known for their innovation, job creation, and financial growth. Yet, some suffer from severe issues with inexperienced owner-managers, lack of resources, and competition that can significantly hinder their chances of success. The small businesses that struggle or are faced with closure represent an essential part of the economy that cannot be overlooked. However, despite their value in the economy, many still struggle due to multiple factors, including unskilled or incompetent leaders and owners, challenges related to technical expertise, and funding issues, including increased business costs that can be exacerbated by poorly performing owners or managers, who in turn may negatively affect employees as well. In fact, in developed countries, small businesses contribute 40% to 60% of the gross domestic product (GDP) and 67% of employment. The research presented here confirms that the workplace is crucial in improving teamwork from the general perspective and approach. The findings can contribute to a better understanding of the transformational leadership style for all management levels and the effect on the job satisfaction of all employees hired by small business entities in the United States.

The aim of the research: to investigate the features of the comorbid course of chronic kidney disease (CKD) (chronic pyelonephritis), non-alcoholic fatty liver disease and obesity, depending on the stage of CKD.
To achieve this goal, 250 patients with chronic kidney disease (CKD) (chronic bilateral pyelonephritis) stage I–III were examined, of which 160 patients had concomitant NASH and class 1 obesity (1 group) and 90 people had CKD stage I–III without NASH and obesity (group 2). Depending on the stage of CKD, patients of group 1 were divided into 3 subgroups: with CKD stage I – 63 patients, with CKD stage II – 52 patients, with CKD stage III – 45 patients. Patients of group 2 were also divided into 3 subgroups: with CKD stage I – 32 patients, with CKD stage II – 31 patients, with CKD stage III – 27 patients.
The control group included 30 apparently healthy individuals (AHIs). The average age of patients was 49.8 ± 5.8 years. The study did not include patients with CKD stage I–III with nephrotic syndrome and patients with chronic uncomplicated pyelonephritis in the phase of exacerbation.
According to the results of our study, we noted a probable effect of nonalcoholic steatosis and steatohepatitis on the functional state of the kidneys in patients with stage I–III CKD: significant changes in glomerular filtration rate, nitrogen excretory function, increased hypoalbuminemia, increased protein in the urine, erythrocytes, leukocytes, the presence of bacteria, compared with patients with CKD without comorbidity. There was a significant correlation between a decrease in glomerular filtration rate (GFR), an increase in the intensity of oxidative stress, a decrease in blood glutathione, hydrogen sulfide, hyperproduction of homocysteine, cytokeratin-18, connective tissue components (collagen, sialic acids).
In patients with CKD stage I–II without comorbid NASH and obesity, we found a significantly higher renal functional reserve in response to water-electrolyte stimulation, which is sufficient in both groups of patients (increase in GFR by 28–37% vs. 19–31% for comorbidity with NASH). In patients with CKD stage III with nonalcoholic steatohepatitis we found a significantly reduced functional reserve of the kidneys (increase in GFR by 8.9% vs. 17.5% in patients without NASH), and in 4.9% of patients with comorbidity ­– no functional reserve of the kidneys (p > 0.05), indicating irreversible changes in the functional state of the kidneys.

A study with three independent experiments for the seeds of three vegetable species was set at the roof top of Sunway Dormitory near the Bus Terminal, Dinajpur, Bangladesh, during March to May, 2019. The aims were to evaluate the physiological fluctuations in the seeds of sweet gourd cv. Monitaraprimed with the aqueous solutions of H2O2 and to find the suitable concentration. Each experiment had eight treatments: T1 (control/no priming), T2 (hydro-priming in plain H2O) and other six aquatic solutions of H2O2: T3 (0.5), T4 (1.0), T5 (1.5), T6 (2.0), T7 (2.5) and T8 (3.0%). The seeds were soaked for six hours in those seven media (T2 toT8). The seeds were dibbled in wooden seed flats filled-in with coarse sand. The experiments were laid-out in the Randomized Complete Block Design with three replications. Data collected for the 13 traits viz. % germination, % abnormal seedlings, shoot length, root length, seedling length, shoot dry matter, root dry matter, seedling dry matter, number of secondary roots (>1cm) per seedling, number of true leaves per seedling, relative growth rate, seedling vigor index, and root : shoot ratio (dry weight basis). Except the first two traits, the rest 11 were collected at three stagesviz.10, 20 and 30 days after dibbling (DAD). It was lucid that H2O2 was significantly (Pâ‰¤0.05%) effective to improve most of the traits noted. Treatment T4 (1% concentration) was utmost helpful for sweet gourd and >1.5%, others were toxic and hindered the maximum parameters for all the three species. Nevertheless, further studies with different varieties of those three vegetables species with variable doses of H2O2, priming time and temperature could be explored before drawing valid conclusions.

IMPACT OF CORONAVIRUS ON AIR QUALITY: BENEFITS OVER HARM?
Authors: Singhania Sriyash
Published: November 2021

The coronavirus pandemic is one of the most devastating crises in recent times. The first coronavirus case was reported on the 31st of December 2019 in Wuhan, China (World Health Organization, 2020), and, to date (as of May 2021) more than 170 million cases have been reported, with 3.54 million deaths, in 220 countries and territories (Worldometer). With the advent of the coronavirus, there has been a considerable impact on the environments air quality. This study does two case studies - in New York and New Delhi - to evaluate the change in air quality before and during the pandemic. The lockdowns led to the closure of public spaces, with limited access to only the essentials. However, owing to the lifting of these restrictions, the emissions of air pollutants have again soared to extremely high levels, outweighing the benefits of the reduction in emissions of pollutants during the peak of the pandemic.

O objetivo geral deste trabalho é analisar como a estrutura de propriedade influência os custos de agência nas instituições financeiras listada na B3. Os procedimentos metodológicos, são descritivos com abordagem quantitativa, a amostra composta por 26 companhias, analisadas no período de 2014 a 2018. A coleta de dados deu-se por meio formulário de referência para métrica de estrutura de propriedade, enquanto a métricas dos custos de agência deu-se por meio da Taxa de Retorno sobre o Ativo (TRA) e para a Relação Despesas com as Vendas (RDV) extraída das demonstrações financeiras. Os resultados encontrados indicam uma relação positiva de 0,196 entre as variáveis TRA e Participação Acionária com Nível de confiança de 99%; e também identificou-se relação positiva entre as variáveis TRA e RDV de 0,380, a nível de confiança de 95%. O teste de médias de Wilcoxon-Mann-Whitney apontou que as empresas com participação acionária maior que 51% demonstram médias iguais às instituições com participação menor que 51%; no que se refere aos custos de agência referentes à variável TRA. Assim, as instituições com maior estrutura de propriedade demonstram melhores aplicabilidades dos ativos, e, dessa forma, menores custos de agência; as Joint Venture apresentam maiores custos de agência quando comparada com as companhias com controle individual; e, por fim, as companhias com capital votante maior que 51% também possuem maiores custos de agência quando comparado com aquelas com participação menor que 51%.

Published: October 2021

O agronegócio possui grande representação no setor econômico brasileiro com significativa participação no PIB. Contudo, trata-se de um dos segmentos com o maior número de acidentes ocupacionais e alta prevalência de riscos ergonômicos. Logo, esse artigo objetivou diagnosticar, sob enfoque da ergonomia e da qualidade de vida no trabalho (QVT), a realidade de trabalhadores rurais, utilizando como modelo de estudo uma empresa familiar agrícola no estado de São Paulo. A partir de uma pesquisa exploratória e descritiva, aplicou-se o método observacional assistemático e coletou-se dados por meio do Questionário Nórdico de Sintomas Osteomusculares (QNSO) e do Questionário World Health Organization Quality of Life (WHOQOL-bref), seguindo-se de tratamento estatístico descritivo e inferencial. Os principais pontos de dores identificados referiram-se ao quadril/membros inferiores (40%) e região dorsal (40%), associando-se esses relatos às atividades repetitivas, alta incidência de trabalho estático, movimentação manual de carga e má postura observadas in loco. Estatisticamente, verificou-se que as dores na região dorsal estão relacionadas ao tempo de trabalho na função (p = 0,009), bem como há relação com os desconfortos da região cervical (p = 0,001). Ainda, os trabalhadores apresentaram elevada QTV (3,9 ± 0,7), apontando como única fragilidade a influência do sono no trabalho (2,7 ± 1,1). Constatou-se que manifestações de dores e desconfortos deve-se à falta de alinhamento das atividades laborais com os preceitos ergonômicos, porém sem impacto direto na QVT na amostra estudada. Esse artigo contribui para discussões gerenciais sobre planos e práticas que prezem pela saúde e bem-estar do trabalhador agrícola para otimizar indicadores sociais e econômicos no agronegócio brasileiro.

Published: October 2021

Savings is increasingly being acknowledged as a powerful tool for poverty alleviation but the peri- -urban households who are mostly, low cadre workers, peasant farmers and small-scale business owners lacks savings services. This study analyzed savings mobilization on poverty alleviation among peri-urban households in Kwali and Bwari Area Councils Abuja. Cross-sectional primary data was used in this study. The data was collected with the aid of a well-structured questionnaire administered to 185 peri-urban farming households. Descriptive statistics (mean, frequency and percentage), Foster Greer Thorbecke index and ordered logit regression were used to analyze the collected data. The results that emanated from the analysis reveals that 98% of respondents are within the economic active age while 82% of them had formal education and average household size of 4 person. About 93% of households saved in one form or the other. About 51% of the respondent are non-poor while 49% are poor based on analysis of poverty status which revealed poverty incidence of 49%, poverty depth of 28% and poverty severity of 56%. The results further reveals that primary occupation and education reduces the likelihood of not being poor, but there is an increment in the likelihood of being very poor while farm size, savings, access to credit and income generated from secondary activities increases the probability of being non-poor, but reduces the probability of being very poor. Therefore, households should be encouraged by Governmental agencies to engage in secondary economic activities for multiple stream of income to improve on their poverty status. In addition, government should facilitate the establishment of Financial Institutions in the Peri- Urban areas to inculcate saving habit among the people.
Current Anticoagulation Recommendation for COVID-19 Patients
Authors: Prasetya Indra
Published: October 2021

Thromboembolic events in COVID-19 patients can be one of the factors that aggravate the disease and increase mortality. When severe hypoxemia and hypotension occur in COVID-19 patients, the possibility of embolism should be considered. As a result, anticoagulant therapy in COVID-19 patients has an essential role in lowering disease severity and mortality. Many studies report that giving anticoagulants to COVID-19 patients can reduce mortality. Therefore, it is important to understand the role and use of anticoagulant therapy in cases of COVID-19. Several guidelines that have been issued by several health organizations in the world and Indonesia can be used as guidelines for clinicians to start anticoagulant therapy in cases of COVID-19. Various anticoagulant drug regimens have also been recommended to be used both as prophylaxis and as therapy for thromboembolism that can occur after COVID-19 cases.

Authors: Kamelia Irma , Kurnianigsih Novi
Published: October 2021

Background: Peripheral arterial diseases could be a major burden for the health system with a wide clinical spectrum from asymptomatic to limb-threatening. Sudden onset of limb deteriorations represent a vascular emergency and need proper treatment for limb preservation and life-saving. It is still challenging to choose proper management to reduce morbidity and mortality, despite the various advance in diagnostic and therapeutic tools were available. Objective: This case report aimed to elaborate on the management of acute aorto-illiac occlusion with bilateral limb ischemia underwent direct catheter thrombolysis in an older patient. Case Presentation: A 70-years-old man came to our hospital with a chief complaint of leg pain in both of his legs, suddenly since 18 hours before admission. He had paresthesia and paralysis in both of his legs. And the Doppler ultrasonography result was occlusion proximal to the right and left common iliac artery. Then we performed percutaneous intra-arterial thrombolysis using streptokinase with a successful outcome of peripheral revascular- ization but with gastrointestinal bleeding as an adverse event. Conclusion: Despite the various advancement of diagnostic and therapeutic tools available today, Acute Limb Ischemia (ALI) still proceed to be related to increasing major amputation and mortality rates in 20% of patients, more often due to the existing comorbidities such as other atherosclerotic diseases.

Background : A newly emerging pandemic of Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory coronavirus 2 is responsible for significant morbidity and mortality worldwide. As one of the effects is hematological changes related to the COVID-19 infection causing patient tend to thrombosis than hemorrhagic. Current review of evidence and statements on management of coagulopathy and thrombotic complications related to this novel disease is needs to be explored Case : Male 53 years old referred from Private Hospital, due to Severe pneumonia due to COVID-19 and Acute Limb Ischemia. This patient was assessed as Pneumonia COVID-19 severe with acute limb ischemia bilateral grade IIB and performed bilateral surgical thrombectomy with antegrade approach using fogarty catheter with the result was thrombus 10cm along the left femoral artery and thrombus 2cm in the right femoral artery. Discussion : With consideration of atherosclerotic diseases in this patient, we decided to give rivaroxaban as an anticoagulant combined with aspilet and statin high dose. But due to lack of source in our hospital, and patient also denied for further management, treatment for the patient cannot be optimal, so the patient discharge with unresolved limb ischemia. Conclusion : This case showed that the increase risk of heparin resistance in SARS-CoV-2 patient, it is recommend- ed to monitor heparin activity of UFH treatment based on anti-Xa levels instead of aPTT alone.
The Role of Shiite Clergy in the Constitutional Movement at the Initial Stage of the First Iranian Revolu-tion of 1905–1911

Published: October 2021

The article highlights the history of the development of the Constitutional Movement in Iran in 1905-1906, i.e. in the first period of the Iranian Revolution of 1905–1911, and the participa-tion of the Shiite clergy in it. Shiite clergy, dissatisfied with the attempt of the Shah and his entou-rage to weaken their rights in the area of legal proceedings, as well as with the government's policy aimed at “Europeanizing” Iran, took an active part in the protest movement. The article reflects the period of the emergence of secret revolutionary societies in the country, created by representatives of advanced bourgeois intelligentsia of Iran. The leaders of Shiite clergy joined them, and later began to create and lead such societies themselves. The author focuses on the role and influence of Shiite clergy in the revolutionary activities of various secret societies, such as “Enjomene Mahfi”, which included the main leaders of Shiite clergy of Tehran: Ayatollah Sayyid Abdollah Behbehani and Said Mohammed Tabatabai, politician M. Kermani and others. These organizations carried out a great deal of work among the believers: they published political leaflets, appeals to the Iranian people, called on the people to speak out against the Shah's tyranny and European penetration. The revolu-tion showed the potential of Shiite clergy as an active factor in the socio-political history of Iran.
Modern Approaches to the Study of Islamic Soteriology
Authors:   St. Petersburg State University, Shavrina Maria Svyatoslavovna
Published: October 2021

The article is dedicated to the research methodology of Islamic soteriology in the field of re-ligious studies. The main focus is on empirical and theoretical research paths. It is noted that Islamic soteriology as an object of study can be considered through sociological tools, religious and technical terminology as well as from the point of view of religious exclusivism, inclusivism and pluralism. Based on the analysis of relevant sources, this paper points out the conceptual series of Islamic sote-riology and highlights key personalities of Muslim theologians whose works contain the issues of salvation. The research demonstrates that the basis of Islamic soteriology study is methodological and ideological pluralism. The author concludes that the pluralism inherent in Islamic thought pro-vides a golden opportunity for modern scholars and Muslim theologians to formulate an optimistic soteriology in the fold of Islam and extrapolate its positive consequences to the area of interreligious dialogue.
Birthplace Revisited – a look at Humanity in Nnedi Okorafor

Enquanto berço derradeiro da Humanidade, África é um terreno fértil para escritas e reescritas da História humana. As tragédias e as atrocidades do seu percurso civilizacional acrescem à relevância de refletir sobre a Humanidade com recurso a África. Também por isso, a ficção científica africana (AfroSciFi) tem um papel central no pensamento utópico e distópico do século XXI. Na dianteira da literatura africana tem estado a Nigéria, com contribuições notáveis como as de Chinua Achebe e Chimamanda Ngozi Adichie. Na segunda década do século XXI irrompe o trabalho de Nnedi Okorafor como voz afrofuturista, cosmo/afropolitana. Todos três partilham uma escrita altamente politizada e a total oposição a leituras redutoras e dogmáticas do mundo e, particularmente, de África., assim como uma tradição híbrida de formação ocidental(izada) em contexto Africano, com ecos da experiência agreste de opressão. Rejeitar a “narrativa única” e todos os estereótipos é um tópico contante na ficção Africana contemporânea e quando o trabalho de Nnedi Okorafor chega à Nigéria as possibilidades já são ilimitadas e unir passado e futuro Africanos é simultaneamente factível e desafiante.

A theory of multicomponent diffusion based on Fick's law is proposed, where, when writing the Maxwell-Stephen equations, a multicomponent mixture is represented as consisting of two components: the isolated substance and all the others with average characteristics. The number of diffusion coefficients is significantly reduced, the method for their calculation is indicated, and they strongly depend on the concentration of the mixture components. Based on the results of this theory, the combustion of an H2/O2 mixture with an equivalence ratio equal to unity was simulated. For each component, great chemical work is carried out with alternating signs, but in total they partially destroy each other. Also, in the chemical reaction zone, there is a strong change in the stoichiometric ratio of the H2 and O2 components.

Heat transfer in capillary pumped loops (CPL) is carried out by transferring the mass of the circulating coolant in the form of liquid and vapor. Therefore, the hydrodynamics of the phases in the CPL determines their heat transfer capacity (heat flow or the product of the heat flow by the heat transfer length). The influence of structural, hydraulic and thermo-physical properties of capillary structures used as capillary pumps in two-phase thermal control systems (Loop Heat Pipes - LHP) on their heat transfer capacity has been analyzed. Methods of increasing the heat transfer capacity of LHP, due to the use of anisotropic capillary structures with a decrease in pore sizes in the direction of the vaporization zone, have been determined. The conditions of LHP operability and the method of analytical calculation of the temperature field in anisotropic capillary structures for a model with pseudo-convection have been considered. The calculated and experimental data have been compared.

Antireflection coating, ohmic contacts and mesa-structure forming stages have been reviewed. The technology of n+-GaAs contact layer etching with the help of plasma-chemical, liquid and ion-beam etching has been investigated. Antireflection coefficient of radiation from the heterostructure with TiOx/SiO2 (x close to 2) antireflection coating surface was less then 3% in wavelength range 450-850 nm. The value of contact resistance for n- and p-type conductivity was 3E−5 − 3E−6 ohm · cm2, the decrease of photosensitive region shading degree at increased bus-bar conductivity has been archived. The mesa-structure surface current leakage decreased to the value of E-9 A at voltage less then 1 V.
Modern Evolutionist Naturalism And Šankara’s Arguments Contra Sankhya
Authors: Shokhin Vladimir K.
Published: November 2021

This comparative study aims at juxtaposition of modern Western naturalistic evolutionism and the mostly similar attitude in the classic Indian philosophy in the shape of Sankhya’s cosmology in the context of their corresponding critiques by contemporary creationists and Advaita-Vedanta. The long and pointed polemics with Sankhya in the Brahmasutrabhasya by Šankaracharya (7th-8th centuries A.D.) is in the focus of this investigation along with numerous references to the Sankhya-karika by Isvarakrsna (5th century A.D.) as the basic text of the philosophical school criticized by its most powerful opponent. Comparing Western and Indian evolutionism reveals some very important differences to such a degree that the Indian species of the genus would be, in the author’s opinion, better identified as not evolutionism in the strict sense but as a “développisme” combining features of evolutionism with those of emanationism. As to Sankhya’s naturalism, it turns to be much more “sophisticated” than that, e.g., of Thomas Huxley or the so-called New Atheists because its “stuff” is more psychological than material. Nevertheless, crucial logical gaps remain the same in both cases (along with an antitheistic “faith” instead of rationalism), while their taking into account by opponents of naturalism offers a challenge for comparative philosophical theology.

Authors: Padilla Patiño Rosalía , Ramírez Miranda César Adrián , Rosas Landa Ramos Octavio
Published: November 2021

This paper presents a conceptual approach to the study of the urbanization process in the Metropolitan Area of Valley of Mexico (ZMVM), from the perspective of the social production of space and its capitalist appropriation. The aim is to contribute to the understanding of the problems derived from the expansion and metropolitan urbanization of Mexico City, among which the precarious living conditions of the population integrated to the metropolitan area stand out, as the expression of the contradictions inherent in the social production of space in capitalism.
For the research, a mixed methodology was used to combined classical theoretical sources with the empirical reference gathered in documentary sources and field observations; offers a historical perspective and an interdisciplinary effort. The main contribution of the article is to underline the contradictory nature of the metropolitan expansion process and the continued subordination of rural space to urban dynamics. It concludes by highlighting the possibility and need to strengthen forms of social production of space focused on the reproduction of life rather than the reproduction of capital.
Educación remota y pandemia: experiencias de padres de familia
Authors: Ortiz Nava Edna Karina
Published: November 2021

The paper presents an analysis of the experiences of parents and emergency remote education, implemented by the Ministry of Public Education (SEP), due to the COVID-19 pandemic. It is a phenomenological investigation, supported by the semi-structured interview, which outlines the use of ICT, through platforms and digital resources, and the process of appropriation by parents in virtual environments; its objective is to investigate what are the challenges they have faced in this period, in order to redefine this information. The work is presented in three sections: in the first, the problem is contextualized; the second presents the theoretical references and instruments used; and the third, the review, systematization and interpretation of the data obtained.
The research shows the heterogeneity of the educational environment in public schools, the little recognition of the teaching work, the functions of parents and a task for which they were not prepared. This conjuncture reveals the urgency of reworking the educational model and adapting it to the context, as well as creating educational policies, whose central axes are in the permanent updating, in the immediate attention of deficiencies and needs of the educational actors, and in providing connectivity and literacy digital to all of them.
