Frequency of Hypothyroidism in Patients with Fibromyalgia Syndrome.
Authors: Naji Ragad I. , Turki Kismat M. , Al-Osami Mohammad H.
Published: August 2023

Background: Fibromyalgia (FMS) is characterized by chronic widespread pain and allodynia (pain from stimuli which are not normally painful with pain that may occur other than in the area stimulated) of more than 3 months duration. The current hypothesis of the etiology of FMS includes inflammatory and neuroendocrine disorders. Many features of fibromyalgia and hypothyroidism are virtually the same, and thyroid hormone treatment trials have reduced or eliminated fibromyalgia symptoms. These findings led the authors to test the hypothesis that fibromyalgia patients are hypometabolic compared to matched control .
Patients and Methods: The samples  were taken from the patients attending the out-patient clinic in Medical city-  Baghdad Teaching Hospital – Rheumatology and Rehabilitation Consultation Unit , where the anthropometric tests were performed , from the period Nov. 2010 till June 2011
The samples were taken from 57 fibromyalgia patients and 34 apparently healthy controls . Blood samples were collected and T3 , T4 , and TSH were estimated in serum of patients and control .
Results: The present results show that only 6.6% of the FMS patients had elevated serum TSH level , and the T3 , T4 , and TSH results were non-significant .
Conclusion: There is no conclusive evidence of specific thyroid dysfunction in FMS , although , it remains an important diagnosis to exclude when making a primary diagnosis .
HUMAN RIGHTS IN THE CONDITIONS OF URBANIZATION
Authors:   Alfred Nobel University, Bocharova Natalia V.
Published: August 2023

World practice proves that one of the important functions of city self-government in recent years has become the provision of management services that meet local needs and priorities related to the realization of human rights at the local level. Although the primary responsibility for the promotion and protection of human rights rests with national governments, the promotion of a culture of human rights at local level plays a vital role in promoting the respect and realization of human rights in society. The article analyzes the connection between the process of urbanization and the process of "municipalization of human rights", which refers to the transfer of human rights activities to the local level, mainly in cities. It is noted that the trends of socio-political and socio-economic development of the late 1980s and early 1990s of the 20th century, associated with the rapid development of large cities and the creation of urban agglomerations, led to the involvement of cities in the discourse and practice of international human rights, when the latter began to be taken into account in the formation of city policy. It is indicated that the involvement of megacities in human rights activities took place against the background of two phenomena, firstly, the emergence of the concept of "human rights cities" and the formation of a corresponding socio-political movement, which quickly acquired an international character, and secondly, the emergence of the doctrine and global movement for the right to the city. The article reveals their essence and significance. The author concludes the need for further theoretical research in the field of doctrinal and practical aspects of the problem of the connection between urbanization and human rights.
FEATURES OF JUDICIAL PROTECTION OF THE RIGHTS OF BUSINESS ENTITIES DURING THE CONSIDERATION OF BANKRUPTCY CASES
Authors:   Donetsk State University of Internal Affairs, Tolstykh Anna B.
Published: August 2023

The article is devoted to the study of the peculiarities of judicial protection of the rights of economic entities during the consideration of bankruptcy cases. The choice of the topic is due to the relevance of the problem of insolvency of debtors in the light of modern views on the economic development of the country in the conditions of the global and national economic crisis. In addition, not so long ago a new legal act was introduced - the Code of Ukraine on Bankruptcy Procedures, the main purpose of which was announced to speed up court proceedings in bankruptcy cases, increase their efficiency, implement new protective mechanisms for business, so it seems appropriate to analyze the relevant legal institution in the conditions of modernization of the legislation. The article examines the definition and essence of the concept of "bankruptcy", its economic and legal nature. The currently relevant procedure for consideration of debtors' insolvency cases is studied, taking into its specifics and differences from general legal proceedings in the economic process. Attention is paid to the principle of "concentration" of all disputes within the bankruptcy case. An analysis of the national legislation on bankruptcy was carried out, taking into the adoption of the Code of Ukraine on Bankruptcy Procedures. Separate elements of such a procedure are revealed: the procedure for opening, considering and closing insolvency cases, determining the circle of main participants in such cases. The methods of protecting the rights of debtors and creditors, which can be applied by the court in the process of considering bankruptcy cases, are analyzed, for example, the possibility of introducing a moratorium by the court on the satisfaction of creditors' demands, and appeal to the court with a statement on the opening of bankruptcy proceedings was considered as one of the ways of protecting the rights of business entities.
Exploring the Relationship Between Gender and Sustainable Development Competencies in Higher Education Institutions: Insights from a Zimbabwean University
Authors: Zvavahera Promise , Pasipanodya Sheppard , Bogalin Victor , Aquino Emmanuel
Published: August 2023

Denying nearly half of the world's population, which constitutes approximately 49.72% of women, equal access to resources and opportunities means depriving them of the chance to contribute to the sustainable development of the global economy. To gain insights into the challenges faced by female academics in higher education institutions (HEIs) in developing sustainable competencies for a sustainable future, a case study was conducted using mixed methods, focusing on a university in Zimbabwe. The study involved all 43 academics who constituted the entire academic staff of the university. Face-to-face interviews and online questionnaires were employed to collect data from the respondents, taking into consideration the limitations imposed by the COVID-19 pandemic, which made some respondents prefer online interactions. The study revealed a lack of gender mainstreaming in the university's programmes and projects, resulting in unequal participation and limited access to opportunities and resources. Most female academics in the institution lacked critical competencies in research and innovation, interdisciplinary thinking, and granting writing. This disparity was attributed to male academics holding positions of authority and decision-making while controlling a significant portion of resources. Consequently, the study concluded that the institution's prevailing culture, systems, and processes hindered the development of sustainable competencies among female academics, thereby denying them opportunities to fully contribute to building a better future for all. To address these challenges, the study recommended the full implementation of affirmative policies, gender mainstreaming practices, and institutional practices and processes that would enable equal participation in all spheres of life, calling for a profound shift in policy implementation and a change in the mindset of leadership and individuals within HEIs. The study illuminates the ways in which gender influences the acquisition, growth, and utilisation of sustainability knowledge and skills among academic staff in HEIs.
Unflavored Excitations of Nucleon-Nucleon States in Terms of a First-Order Mass Formula
Authors: Bevelacqua Joseph
Published: August 2023

The possibility that hadrons could exist with structures beyond conventional qq or qqq quark configurations was noted by Gell-Mann1. Clement et _al_.2 provide an example of these exotic hadrons in the unflavored dibaryon sector as illustrated through both elastic nucleon-nucleon (NN) scattering and NN-induced pion production. 

     Clement et _al_.2 address three specific unflavored excitations of the nucleon: (1) X(2148) Jπ=2+, X(2140) Jπ=1+, and d*(2380) Jπ=3+. These states are addressed in terms of a first-order hexaquark mass formula as proton (uud) and neutron (ddu) baryon clusters. The first-order hexaquark model predicts a state with a mass of 2180 MeV/c2 with a Jπ = 0+ or 1+ spin assignment. The model mass result is within 2% of the X(2140) J=1+ state.
An alternative foundation of quantum theory
Authors: Helland Inge Svein
Published: August 2023

A new approach to quantum theory is proposed in this paper. The basis is first taken to be theoretical variables, variables that may be accessible or inaccessible, i.e., it may be possible or impossible for an actor to assign arbitrarily sharp numerical values to them. In an epistemic process, the accessible variables are just ideal observations connected to an actor or to some communicating actors. Group actions are defined on these variables, and group representation theory is the basis for developing the Hilbert space formalism here. Operators corresponding to accessible theoretical variables are derived, and in the discrete case, it is proved that the possible physical values are the eigenvalues of these operators. The focus of the paper is some mathematical theorems paving the ground for the proposed foundation of quantum theory. It is shown here that the groups and transformations needed in this approach can be constructed explicitly in the case where the accessible variables are finite-dimensional. This simplifies the theory considerably: To reproduce the Hilbert space formulation, it is enough to assume the existence of two complementary variables. To focus only on physical variables rather than mathematical variables, the concept of inaccessible variables is then replaced by the concept of notions, and in this connection, aspects of category theory partly replace group theory. The interpretation inferred from the proposed foundation here may be called a general epistemic interpretation of quantum theory. A special case of this interpretation is QBism; it also has a relationship to several other interpretations.

Introduction. Today obesity is becoming an epidemic, with the problem of an increasing prevalence of periodontal tissue disease in the population. There is increasing evidence in the literature of the relationship between periodontal health and body weight. Our study aimed to evaluate the condition of periodontal tissues of overweight patients. Patients and methods. In this cross-­sectional study, 44 patients were evaluated. 31 overweight/obese patients were included in the main group, 13 patients with normal body mass index (BMI) formed the control group. PMA, Fush and Silness-­Loe indices were used to assess periodontal status. Results. An analysis of the relationship between the PMA and Fush indices and the presence of overweight/obesity showed statistically significant differences (p = 0.006). A higher incidence of advanced chronic generalized periodontitis was observed in overweight/obese patients compared to normal weight patients (p = 0.007). The odds for advanced chronic generalized periodontitis were 10,0 times higher in overweight/obese than in normal weight patients (95% CI 1.87–53.48). Conclusion. Our findings indicate that overweight patients had more severe chronic generalized periodontitis than normal-­weight patients.

Introduction. Adolescence is a period in which many adolescents start exploring certain risky behaviours like tobacco use. Adolescent tobacco use is a significant global public health challenge. This study was conducted to determine the intention to smoke tobacco products among coeducational senior secondary school students in Uyo LGA, Akwa Ibom State. Materials and methods. A cross-­sectional study was conducted among 200 senior secondary school students aged 10–19 from January 2020 to December 2020. A multi-­stage sampling technique was used to select respondents from four senior secondary coeducational schools. Data were collected using a semi-structured interviewer-­assisted questionnaire. Results. Mean age of respondents was 15.3 ± 1.4 years, and 110 (55.0%) of them were males. The prevalence of intention to smoke tobacco products among the respondents was 75 (37.5%). 43 (21.5%) of them reported peer pressure as the reason for their intention to smoke. 190 (95.0%) of them knew that cigarette smoking is harmful to their health. There was a statistically significant association between respondents’ sex, ever smoked, currently smoking, age at first experience, last experience, having a sibling that smokes, having friends that smoke, and intention to smoke tobacco products (p < 0.05). Conclusion. Adolescents with these risk factors should be prioritized by smoking prevention efforts.

Published: August 2023

In this research, we discuss the removal of basic fusion (BF), and crystal violet (CV) dyes by strontium hydroxyapatite supported BiOI. In a modified hydrothermal model, one can synthesize BiOI/SrHA. BiOI/SrHA was characterized using Fourier transform-infrared spectroscopy (FTIR), UV-visible (UV-vis) analysis, X-ray diffraction (XRD), energy diffraction X-ray (EDX), and scanning electron microscopy (SEM). SEM outcome confirmed the dispersion of BiOI onto strontium hydroxyapatite. The shape of the BiOI catalytic samples overlapped with each other to form 3D hierarchical flower-like structures. The UV-visible was used as a radiation source during photocatalysis. BiOI/SrHA had an effect on malachite green dye degradation. The oxidative removal occurred through hydroxyl radical formation. UV-visible (UV-vis) BiOI/SrHA showed perfect photocatalytic property for the decay of Basic Fuchsin (BF) and Crystal Violet (CV) from an aqueous solution. According to kinetics analysis, the dye degradation rates could be in a pseudo-first-order model

Prospects of Russian regions for the transition to a new technological order
Authors: Tukhtarova E. K.
Published: August 2023

The article presents the analysis of Russia’s potential to transition to a new technological order. The potential assessment was carried out on the basis of the obtained level of manufacturability in the Cobb—Douglas production function as an indicator reflecting long-term technological trends, the available resource potential, the efficiency of its use and the country’s ability to transition to a new technological order. The conducted research has shown that since 2014, the country has been undergoing a restructuring of the level of technology, caused by a decrease in the return on capital against the background of a stretched process of innovation in the economy. One of the limitations hindering the successful transition to a new technological order is regional differentiation in the level of technology, which can be explained by the excessive accumulation of old technologies and the discrepancy in the skill level of the workforce, as well as significant differences in the level of knowledge and skills among regions.

Foram analisados 19 casos de neoplasias malignas primárias da vesícula biliar, que passaram pela seção de cirurgia abdomino pélvica do Instituto Nacional de Câncer no período de 1962 a 1972. O tipo histológico mais comum foi o adenocarcinoma, afetando, principalmente, pacientes do sexo feminino, numa faixa etária entre 50 e 70 anos. Observamos colelitíase associada em 10 casos. As metástases ocorreram com maior freqüência para o cólon. Os melhores resultados foram obtidos em casos de tumor inicial, restrito ao órgão. O cálculo da sobrevida foi prejudicado, uma vez que em 12 pacientes perdeu-se o follow-up. Por ser uma doença de difícil diagnóstico, concluímos que o futuro do tratamento está no progresso dos protocolos quimioterápicos e dos métodos propedêuticos visando diagnóstico precoce, onde a cirurgia obtém os melhores resultados.

Corporate Minimum Tax Options
Authors: Mintz Jack M. , Venkatachalam V. Balaji
Published: August 2023

Canada faces a quandary. Should it adopt a corporate minimum tax under the pillar two agreement that is consistent other agreeing countries, or should it adopt a US-style corporate alternative minimum tax that is more harmonized with the minimum tax of the United States, its largest trading partner? There is no easy answer to this question. The pillar two corporate minimum tax is complex and distortionary, even though it puts a floor on tax-rate competition at 15 percent; but a made-in-Canada corporate minimum tax could reduce distortions while raising more revenue by being applied to a wider group of companies. The authors of this paper argue that Canada should take its time to see whether the US corporate alternative minimum tax qualifies as a minimum tax, giving Canada better options for a corporate tax than pillar two's global tax.

This study evaluated the responses of runoff and soil erosion to a clear-cutting period of Acacia plantation in a headwater mountain. Two plots with 15m2 (3m width*5m length) were installed in a headwater mountain of Hoa Binh, Vietnam. Plot 1 remained untreated as the control plot, while plot 2 was clear-cutting in March 2019. Runoff and soil erosion was observed from April to September 2018 for the pre-cutting period with 55 storm events and from March to May 2019 for the post- cutting period with 15 storms-events. Observed data was examined the effects of the cutting period by using paired-plot analysis that compared the control plot and the treatment plot. The main results included: (1) Surface runoff after clear-cutting increased statistical significantly from 0.18 mm storm-1 (corresponding to 0.38 %) to 0.26 mm storm-1 (corresponding to 0.56 %). Paired- plot analysis showed the increase of surface flow is 81.14% after cutting; (2) Soil erosion increased statistically significant after clear-cutting from 228.44 g/storm to 309.27 g/storm on average, the amount of soil erosion due to treatment effect increased 33.1 %. The increase of runoff and soil erosion is quite high after the cutting period. This suggests that plantation management practices to control runoff and soil erosion in the headwater basin are necessary for Vietnam.

The use of dump soils for the rearing of African giant land snail (AGLS) leads to the bioaccumulation of metals and microbial loads in AGLS, which is a major food chain route for the human body. This study investigated the concentrations of heavy metals (As, Cd, Cr, Hg, and Pb) and microbial load in AGLS reared with dumpsite and control soil and also to ascertain if they are within permissible limits. Soil samples; dump soil (A), and Control soil (B) were collected at 0-30 cm depth with the aid of a soil auger and were used for AGLS farming, to ascertain whether the Toxic elements (TEs) concentration was within the permissible limits on AGLS consumption. A total of 18 juvenile snails of similar weights was used for the study. The experiment lasted for three months (90 days), during which the snails were subjected to similar dietary reign and equal quantity of feed. The soil samples were analyzed for TEs before and after farming, and a snail was also analyzed for TEs after farming using an atomic absorptions spectrophotometer (AAS). Standard methods of APHA were used to determine microbial loads such as Total heterotrophic bacteria, E. coli, total coliform, fecal coliform, Staphylococcus aureus, Salmonella, and intestinal parasites. Results indicated that bacterial counts recorded in this study exceeded the recommended levels by WHO and ICMSF, standards (i.e. 10 to 102 coliforms g-1, 10 fecal coliform g-1, and 4.9×106 aerobic count g-1). The result shows a significant difference (P<0.05) between the dump and the control soil The concentration of TEs (As, Cd, Cr, Hg, and Pb) in snails reared with dump soil were 2.20, 2.68, 1.08, 2.23, and 2.89 mg/kg respectively. The control recorded 0.28, 1.89, 0.36, 0.16 and 0.24 mg/kg. The values were greater than the maximum permissible limit of 0.5, 2.0, 0.3, 0.1, and 0.1 mg/kg respectively recommended by FAO/WHO compared to the control. The study concludes that snails bioaccumulate toxic elements and microbial loads from the soil used in rearing them which is deleterious to human health when consumed.

Published: August 2023

Human-wildlife conflict (HWC) occurs in various forms throughout the world, with a greater influence in developing countries. This is due to fast increasing human populations and increased subsistence agriculture, which reduces wildlife habitat and increases human-wildlife interactions. Wild animals fight for resources with humans in the Arjo Dhidhesa Sugar Factory in Western Ethiopia, and they are in conflict with each other. As a result, this research was carried out to determine the reasons of HWC, as well as the mammals responsible for them. From August 2017 to March 2018, researchers utilized questioner and interview approaches to examine community perceptions toward wildlife and overall cthe result showed that a total of 99.034 sugarcane stalk damage events were registered in all three sample sites both during the dry and wet seasons. Wildlife consumed 46,468 sugarcane stalks during the rainy season, while 52,566 stalks were consumed during the dry season, with the documented damage event varying greatly from site to site. Hippopotamus, Anubis baboon, Warthog, Bush pig, and Buffalo were the most affected by HWC, with agricultural loss occurring throughout both wet and dry seasons. During the wet season, Hippopotamus 16,133 stalks per ha were the most damaged, followed by Anubis baboon 12,484 stalks per ha. Buffalo 5,083 and Bush pig 3,931 stalk per ha did the least damage, placing fourth and fifth, respectively. During dry seasons, Anubis baboon caused the most sugarcane stalk damage (16, 898 stalks per hectare), followed by hippopotamus (16,533 stalks per ha). During both the wet (t = 4.08, DF = 4, P< 0.05) and dry seasons (t =3.73, DF = 4, P< 0.05), there was a significant difference in the damages caused by mentioned fauna. According to the findings, about 67.9% and 25.2 % of all respondents said that HWC expressed itself in crop destruction and livestock predation, respectively. Habitat damage, agricultural development, a lack of feed, and a rise in the population of wild animals are among the explanations cited by respondents. Some of the key crop raider mitigation strategies revealed in this study that were adopted by the investment community and local communities include hanging dead animal parts, habitat disturbance, keeping animals alive by tying them to the side of field, and mass murdering wildlife. These practices are one of the main causes of the extinction of wildlife, making conservation even more challenging. There are currently many human activities in the field of science, which has resulted in many HWCs. As a result, investment decisions should be made based on strong and viable domain choices both commercial and environmental, as well as promoting natural tourism as a viable option for education and conservation education.

Authors: Rahmat Ali
Published: August 2023

The waste of date palm seeds is abundant in Indonesia, however, the seeds are still regarded as trash from the manufacture of date palm-based products. Dates seed, when processed further, can be a useful resource, one of which is as a raw material in the production of Biochar. The utilization of date palm seeds into biochar is one strategy that can be applied. The purpose of this study was to determine the chemical properties of biochar derived from the seeds of palm date (Phoenix dactylifera L.). Making biochar is done by burning the seeds using a furnace with a temperature of 250°C and 350°C, then ground and sieved with a size of 350 micrometers carried out at the Research Center for Limnology and Water Resources. Chemical property analysis using X-Ray Fluorescence Spectrometer (XRF) at the Lampung Advanced Characterization Laboratory- BRIN. The results show there are four macronutrients found in date palm seed biochar namely P, K, Ca, and S. Most composition is Potassium (K). The potassium content of biochar burned at 250 °C is 66.24% while the biochar burned at 350 °C contains 67.189%. In addition, the phosphorus (P) content of biochar burned at a temperature of 250 °C is 6.574% while the biochar burned at a temperature of 350 °C contains 7.429%. Increasing the temperature increases the percentage of Potassium and Phosphorus, but the opposite results in Sulfur (S) and Calcium (Ca).

In agriculture practices, besides animal, human activity belongs to the enemy of Grey-headed Lapwing (Vanellus cinereus). This study aims to analyze the farmers’ perception on Grey-headed Lapwing existence in paddy field surrounding Gifu University, Japan. There are 10 farmers who are work in the research area. All of them are farmers. Descriptive method was used in this study, the data were collected with questionnaire. The finding show that farmers ignore the existences of Grey-headed Lapwing. They saw the nest of Grey-headed Lapwing in unplowed area as many as 60% and they found the nest in plowed area (soil tillage) as many as 40%. Although Grey-headed Lapwing has great defense to attack the enemy, but they prefer breeding in safety place. In this case, when human activity do their work in soil tillage period, it can ruin the nests. It means that human activity is one of the factors that influencing the breeding success of Grey-headed Lapwing.
