Aflatoxins are the carcinogenic, mutagenic and highly toxic secondary metabolite, which is produced by two species of fungus such as Aspergillus flavus and Aspergillus parasiticus mostly. These two types of fungus contaminate the cereals crops such as maize, cotton, rice and spices. These are naturally occurring toxins all over the world. There are 20 different types of aflatoxins but out of six have significance importance for instance, AFB1, AFB2, AFG1, AFG2, AFM1 and AFM2. Most commonly, AFB1 and AFB2 are present in the maize crops and M1 and M2 present in the milk and dairy products. Even the small amounts of aflatoxins, which may cause the harmful effects in human and liver stocks. They cause many acute, subacute and chronic diseases such as hepatic carcinoma in human. Aflatoxins can pose a significant economic burden. It caused up to 25-30 % approximately destroy the crops all over. Aflatoxicosis detection from the humans as well as animals is very tough because variation may occur, or sign and symptoms may be change due to the suppressor of immune system that cause many chronic diseases. These aflatoxins are determined and analyzed by the many techniques such as chromatographic techniques mostly HPLC, immunoassays, fluorescence spectroscopy and many biosensors which are very essential to check the quality, quantity and concentration of aflatoxins present in food and feeds. So that, there are many methods to limit the growth of aflatoxins from the grain in pre-harvest, during harvest and post-harvest conditions or also control the environmental conditions and managed the proper storages of the grains that may diminish the aflatoxins levels. Furthermore, they are many techniques and biological control methods are used to control the growth and activities of fungus species that cause the toxicity in food and feeds and protect the grains for the uses of human and animals.

Governments globally are stressing on nutrition interventions combined with nutrition sensitive policies and programs to combat malnutrition. Governance at all levels has been identified as a critical element in ensuring success of national nutrition plan. Ethiopia has an integrated approach to addressing food insecurity and malnutrition; however, there is little clarity about the wider impact of government policy on food and nutrition. Overall, there have been notable successes in nutrition policy in Ethiopia, but significant challenges remain unsolved. Multi-sectoral nutrition governance has been hailed as an effective mechanism to reduce undernutrition. Ethiopia has adopted many approaches and has been implementing nutrition programs with some success, but undernutrition remains high for a range of reasons. This political economy analysis of nutrition sensitive agriculture of Ethiopia will address challenges of nutrition program design, coordination, and implementation, and looks at root causes that remain less understood. If these challenges are to be met successfully, greater consideration of how to address rapidly changing food systems in Ethiopia is needed at national policy level. The focus of government policy needs to shift from food availability to broader issues of food acquisition and particularly food affordability, which is mediated through food prices and waged employment. Ethiopia as country tried to combat food insecurity and malnutrition through different approaches. The country developed National Nutrition program, National food and Nutrition policy, National Nutrition sensitive agriculture strategy and the Seqota Declaration, which all are intended to eradicate poverty and reduce malnutrition. To attain the highest possible food security and nutritional benefits for the people of Ethiopia, it is essential that agriculture, nutrition, and health (ANH) sciences and their related research activities work together in an integrated manner.

Malnutrition is a common finding in patients with cancer and can significantly affect disease progress and patients’ survival. Gastrointestinal Cancers (GIC) are amongst the most common cancer types. In gastroin-testinal cancer patients, the prevalence of malnutrition has been estimated to be around 39-67%. Body composition reflects the nutritional status. Bio-Impedance Analysis (BIA) is a noninvasive, time- and cost-effective technique to analyse body composition. This review paper aims to critically summarise the currently available clinical data on the efficiency of the easily obtainable BIA measure, Phase Angle (PA), in the evaluation of malnutrition in GIC patients and on disease progression and prognosis. PubMed database was thoroughly searched, in order to identify clinical studies that explore the role of BIA- derived raw data and weight loss on disease prognosis and progress, as well on assessing malnutrition. Phase angle may be used as a nutritional screening tool in patients with gastrointestinal cancers. However, it cannot distinguish between stages of cachexia. Concerning the role of PA as a prognostic factor, current studies show that PA may be used as a prognostic factor of survival, yet further studies are needed for firm conclusions regarding post-operative complications and disease characteristics. Due to the fact that gastrointestinal cancers are a group of various cancers, further studies should be undertaken, in order to evaluate the role of BIA and PA on all gastrointestinal cancer sites and types.

The beautiful structures of conjugated -systems with three-dimensional shapes have stimulated the curiosity of scientists and contributed to the evolution of science and technology. However, the construction of such distorted structures by multistep transformations often accompanies with undesirable side reactions. Consequently, the mass production of nonplanar-systems has still been challenging despite its utility for accelerating interdisciplinary research. In this article, we demonstrate that the inner double bond cleavage of nanographenes is a rational strategy for creating figure-eight molecules. Treatment of dibenzo[g,p]chrysene (DBC) with sodium dichromate dihydrate selectively cleaves the inner double bond to afford cyclobisbiphenylenecarbonyl (CBBC), which adopts a figure-eight structure. This transformation is scalable up to 23 g. This protocol is also applicable to brominated DBC derivatives. The Suzuki-Miyaura cross-coupling reactions of thus obtained brominated CBBCs afforded the corresponding p-tolyl derivatives, which emit circularly polarized luminescence (CPL) with high g values of more than 0.01. CBBC exhibits various intriguing properties: (1) the spontaneous resolution to afford a conglomerate, (2) configurational stability at room temperature, (3) the formation of a triplet excitation state upon photo-irradiation, and (4) the transformations of carbonyl groups. We also examined the oxidative inner bond cleavage of larger nanographenes, which furnished three non-planar -systems consisting of two figure-eight subunits. These highly distorted structures are difficult to construct by the conventional bottom-up approach, thus highlighting the power of the oxidative inner bond cleavage strategy.

Published: March 2023

This study aims to develop the questionnaire of students’ perception about the real and virtual refutational laboratory which is a misconception remediation method adapted from refutation text using a new approach i.e., laboratory. This study was a quantitative description that involved 53 students (12 males and 41 females) chosen using purposive sampling. The students were initially given a trial questionnaire after receiving a misconception remediation treatment using a real and virtual laboratory method in different classes. The validity and reliability of the instrument were analyzed using Rasch Model. The analysis result reveals that the Cronbach's alpha was 0.61 (enough category), the item reliability was 0.82 (good category) and the person reliability was 0.31 (less variance in students' answers). Meanwhile, based on the validity test, the raw variance was obtained from measures of 29.4% reaching the minimum criteria range of 20%. The Differential Item Function (DIF) test based on gender results revealed that an item was biased (p=0.0435), whereas, there is no biased instrument based on the kind of class in the Differential Item Function test study. The analysis demonstrates that after correcting and deleting some items that did not match based on its criteria, this instrument may be used to gather information on students’ perception regarding the implementation of laboratory learning methods or the like in a valid and reliable way by the researchers and teachers.
Durable Solutions’ Dilemma In The International Refugee Regime. (c2022)
Authors:   ,   Lebanese American University, Srour Lama
Published: March 2023

The International Refugee Regime (IRR) offers three durable solutions for the plight of refugees: (1) local integration in the first country of asylum, (2) voluntary repatriation, and (3) resettlement in third party-states. Despite these devised solutions, in most refugee crises no durable solutions demand is met (Stein, 1986). This is the case for millions of Syrian refugees, who have faced extreme hardship and difficulty since fleeing Syria following the start of the civil war in 2011. Ten years into the crisis, nearly 6.6 million Syrian refugees are displaced across 126 countries, of whom 5.7 million are seeking refuge in five countries neighboring Syria (Lebanon, Jordan, Egypt, Iraq, and Turkey) (UNHCR, 2019). Lebanon, a fragmented state, remains the host with the largest number of refugees per capita worldwide. This dissertation draws international relations theory to explain how and why the IRR failed to ensure durable solutions for Syrian refugees in Lebanon. It argues that, given the anarchical international system in which the IRR operates, responsibility sharing and attaining durable solutions for Syrian refugees hosted in Lebanon will remain unlikely as long as the IRR remains unable to exert policy decisions on states. This thesis demonstrates the ways in which states draw on securitization discourse to justify their non-compliance with and rejection of the durable solutions put forward by the IRR and in turn (re)producing their sovereignty. By analyzing these elements within the specific context of Lebanon, the dissertation attempts to highlight the repercussions of lacking durable solutions for Syrian refugees and provides recommendations for achieving the durable solutions and improving the workings of the IRR.

Remote work plays an essential role during COVID-19 pandemic to help employees proceed in their work. This work mode continues in organizations even after the pandemic. This change accompanies with several modifications in the work environment of the employees among work life balance, work engagement, all the way to employee performance. This study explores the effect of work overload on work life balance, work engagement and their relations to employees performance among remote workers; as self-efficacy moderates the relation between work overload, Work life balance, and work overload, work engagement. A sample of 486 employees work in several sectors in Lebanon serves as the basis for this study. The study revealed opposite results as expected, whereas work overload has no effect on Work life balance and employee engagement. Furthermore, structural equation modeling indicates that self-efficacy moderates the relation between work overload and work engagement, while having no moderation role in the relation between work overload and work life balance.

Published: March 2023

The object of the study is the monetary policy of states at the end of the second — beginning of the third decade of the XXI century. The subject of the study is the tools of monetary policy, changing under the influence of external factors. The purpose of the work is to establish the degree of effectiveness of monetary policy measures of developed countries due to the fact that many of them were taken during the crisis of 2008-2009. However, at present, force majeure factors have imposed on the general turbulence of modern world politics, which required the development and implementation of new monetary mechanisms. The main attention in the article is paid to the United States as a country that actually determines the direction of further development of the world economy, despite forecasts of the imminent loss of the leading role of both the state itself and its currency. Based on the results of the analysis, conclusions are drawn about the inflationary impact of monetary measures taken in covid times to support national economies and financial institutions and it is proposed to intensify fiscal policy to counter inflation in combination with the adoption of monetary measures, since globalization has led to the intertwining of the mutual influence of the financial and real sectors of the economies of both states individually and the world economy as a whole. Conclusions are drawn that if earlier inflation was considered as a negative phenomenon, restraining primarily consumption and investment in production due to a decrease in the number of purchased goods and services, now scientists are increasingly inclined to the need to accelerate inflation as an incentive for accumulation.

The subject of the study is the financial responsibility of a public legal entity to an organization implementing an investment project, which are parties to an agreement on the protection and promotion of investments, in case of violation of the stabilization clause. The purpose of the work is to develop methodological approaches to determining the real damage (including justification and calculation formulas) arising from various deteriorating conditions of the organization implementing the project. Conclusions are drawn that the real damage to the organization implementing the project, in case of violation of the stabilization clause, is to recover the costs of restoring the violated right. Such expenses are the difference between the actual and estimated purchase price of goods (works, services); the difference in the cost of payment for procedures, as well as the payment of sanctions to third parties for violating the terms of concluded contracts (in case of an increase in the time and number of procedures, the establishment of additional requirements and prohibitions to the conditions of implementation of the investment project); an increase in the amount of payments (as a result of an increase in the rate of export customs duties, the sale price and the amount of rent for land plots owned by the state and municipal property); fees for negative environmental impact and use of water bodies; additional costs (incurred in connection with the change of the basis for obtaining the rights of the organization implementing the project to land plots that are in state or municipal ownership, as well as reducing / limiting the scope of rights of land owners /land users /landowners /tenants of land plots and changing the timing and scope of state support measures).

Authors:   Financial University, Moscow, Russia, Eremin V.V.
Published: March 2023

The relevance of the study is due to the complexity of the implementation of state project management in conditions of lack of resources due to sanctions imposed by Western countries on the import of goods and services to the Russian Federation. The subject of the study is integral indicators in the control system of the project approach to ensuring national security. The purpose of the work is to create a methodology for calculating integral indicators to assess the state of national security. As a result of the study, a classification of integral and partial control indicators was formed; the reasons for the low efficiency of using strictly formalized mathematical methods for the formation of integral indicators in project management were identified, which necessitate the establishment of expert methods for determining the weights of particular indicators for their further linear convolution into integral indicators; an approach to expert formation of weights of particular indicators that reduce the influence of subjective expert opinions. Conclusions are drawn that the use of integral indicators of project management control allows organizations to form a more flexible system of control over the implementation of project management in the areas of national security and socio-economic development of the country.

Published: March 2023

This work has aimed to assimilate the obstacles faced by women to achieve success in their professional careers. To achieve this aim, at first, a literature review was carried out with the themes of women working in medium and large companies, female leadership, gender inequality, the division between personal and professional life, and double working hours, enabling the bases of theoretical frameworks for research. Then, the empirical data were gathered from qualitative research through interviews with a semi-structured script. Based on these data, a content analysis was carried out based on the theoretical review and the results of the interviews, and, subsequently, an interpretative assessment based on the reports of the interviewees. Through this analysis, traits that interfere with and assist the female executive career were observed. Behavioral factors linked to organizational guidelines (e.g., machismo) were identified, and that there is still an apparent arduous path for women to reach higher positions in organizations. Another issue encountered is the issue of double working day.

The objective of the study is to estimate the impact of the project "Capacity development and employment generation in the Northeast region of Puno, period 2010-2012" in the income of beneficiary families. The scope of the study corresponds to alaskan households of the districts of Cojata, Ananea and Patambuco whose total beneficiary population was 582 families; The analysis methodology used was based on the Propénsity Score Matching method and the Nearest Neighbor Matching variant. Social, economic, productive and reproductive indicators were used for this. The results indicate that the average effect on the income of the families involved in the project compared to the control group was S/. 580.00. Variables: district, sex, marital status, hectares and skin of young alpacas contribute significantly to the balance and pairing of the data in 7 blocks, while the variables age, number of children and alpacas reduce the probability of pairing. The non-significance of the alpaca variable would explain the nature of the project as an intervention not only with results in the short term but rather that the quality improvement in alpacas occurs in the medium and long term.

It describes the performance of the mining and agricultural sectors during the last two decades, using macroeconomic indicators; In addition, it describes how in this period the Peruvian economy shows an impressive growth of 5.4% in terms of gross domestic product (GDP); This period is also known as the "mining boom". The excellent performance of mining and agriculture sectors contributed to this economic performance. However, despite the economic growth and changes during the last two decades, extreme poverty, malnutrition and childhood anemia are still a serious problem. To eliminate the extreme poverty Peru has to grow at least 6% per year in terms of GDP. This study proposes that mining and agriculture should continue to grow, as well as the other sectors to ensure Peruvian development. The recent recovery of the Peruvian economy is due to the latest mining investments and the interest of the current government in the promotion of private investments.

Published: March 2023

Wind speed forecasting has found economic significance as it can increase operational efficiency. In this regard, an accurate forecast of wind speed is crucial in the application of wind resources. This study is intended to incorporate independent and output variables as the input of support vector regression (SVR) to forecast wind speed of Zanjan and Ahvaz stations in Iran. The independent variables were minimum, maximum, and mean temperatures, relative humidity, precipitation, average visibility, and dew point temperature. The incorporation of independent and output variables were conducted with principal component analysis (PCA) and differential weighting scheme (DWS), respectively. DWS combined the forecasts of linear regression, SVR, and group method of data handling (GMDH) in which the SVR showed the best The forecast of DWS outperformed the other three mentioned models. The incorporation of DWS and PCA (DWS-PCA) improved the forecasts and the capability of DWS-PCA as a novel method was significant in terms of forecast stability. The novel method can be a robust approach for wind speed forecasting in some subjects such as renewable energy, and meteorological decisions.

The article studies one of the most important mechanisms for sustainable development and innovative modernization of modern enterprises – the reproduction of human resources. The authors, using the example of oil and gas companies, conduct a detailed analysis of that process and highlight its key stages. It is shown that the process of reproduction of the personnel potential covers a set of organizational and managerial measures aimed at identifying both the quantitative needs for personnel and the qualitative individual characteristics of employees, which make it possible to clearly determine the required staffing, rank the personnel and predict its development, taking into account the goals and objectives of the company. The authors determined that the basis of the gradation of personnel potential is a comprehensive analysis of the quantitative and qualitative characteristics of the employee, which are concentrated in the so-called “profile portfolio of the employee”. They considered the full cycle of work on the formation of the company’s staffing system and the system for the development of its human resources in a complex and taking into account the needs of specific employees. It is highlighted that modern oil and gas companies are positioned as socially oriented production structures, focused on creating conditions for mobile replenishment of staff needs through the implementation of a detailed and large-scale policy to improve living conditions, social security and the use of free time for employees.

The language and cultural barriers in the multilingual population have risen in Japan and  resulted in the importance of public service translators and interpreters. Understanding thepublic service translators and interpreters’ roles and perspectives in intercultural communication in Japan is interesting and important to be investigated to explore the emotional and psychological impact on their work. Despite several research on translating, interpreting, or intercultural communication do exist, however the public service translators and interpreters’ emotional and psychological impact on their work has generally not been much researched. Therefore, it is necessary and meaningful to study the perspective and role of the public service translator and interpreters in the context of translation and intercultural communication.This research is based on the longitudinal observation and interview with ten public service translators and interpreters in Yamaguchi City, Japan. It was found that their preferences toward their work and other psychological aspects such as willingness to communicate, anxiety, and empathy also influence their role and perspective.
