The article deals with the problem of achieving sustainable development. The purpose of this study is to reveal the relationship between the components of sustainable development, taking into account the involvement of indigenous peoples in nature conservation. Climate change makes achieving sustainable development more difficult. Indigenous peoples are the first to feel the effects of climate change and play an important role in the environmental monitoring of their places of residence. The natural environment is the basis of life for indigenous peoples, and biological resources are the main source of food security. In the future, the importance of bioresources will increase, which is why economic development cannot be considered independently. It is assumed that the components of resilience are interrelated and influence each other. To identify this relationship, a model for the correlation of sustainable development components was developed. The model is based on the methods of correlation analysis and allows to determine the tightness of the relationship between economic development and its ecological footprint in the face of climate change. The correlation model was tested on the statistical materials of state reports on the environmental situation in the Khanty-Mansiysk Autonomous Okrug – Yugra. The approbation revealed a strong positive relationship between two components of sustainable development of the region: economy and ecology.

Genome-Wide Regulatory Interactions in the Early Stages of Drosophila Speciation
Authors:   , Go Alwyn Clark
Published: December 2020

Speciation occurs when reproductive barriers prevent the exchange of genetic information between individuals. A common form of reproductive barrier between species capable of interbreeding is hybrid sterility. Genomic incompatibilities between the divergent genomes of different species contribute to a reduction in hybrid fitness. These incompatibilities continue to accumulate after speciation, therefore, young divergent taxa with incomplete reproductive isolation are important in understating the genetics leading to speciation. Here, I use two Drosophila subspecies pairs. The first is D. willistoni consisting of D. w. willistoni and D. w. winge. The second subspecies pair is D. pseudoobscura, which is composed of D. p. pseudoobscura and D. p. bogotana. Both subspecies pairs are at the early stages of speciation and show incomplete reproductive isolation through unidirectional hybrid male sterility. In this thesis, I performed an exploratory survey of genome-wide expression analysis using RNA-sequencing on D. willistoni and determined the extent of regulatory divergence between the subspecies using allele-specific expression analysis. I found that misexpressed genes showed a degree of tissue specificity and that the sterile male hybrids had a higher proportion of misexpressed genes in the testes relative to the fertile hybrids. The analysis of regulatory divergence between this subspecies pair found a large (66-70%) proportion of genes with conserved regulatory elements. Of the genes showing evidence or regulatory divergence between subspecies, cis-regulatory divergence was more common than other types. In the D. pseudoobscura subspecies pair, I compared sequence and expression divergence and found no support for directional selection driving gene misexpression in their hybrids. Allele-specific expression analysis revealed that compensatory cis-trans mutations partly explained gene misexpression in the hybrids. The remaining hybrid misexpression occurs due to interacting gene networks or possible co-option of cis-regulatory elements by divergent transacting factors. Overall, the results of this thesis highlight the role of regulatory interactions in a hybrid genome and how these interactions could lead to hybrid breakdown by disrupting gene interaction networks.
God and the Anthropologist
Authors: Piette Albert
Published: December 2020

The article aims to be theoretical, and to consider the impact of the word "ontology" in anthropology. I will start from an observation of religious worship, in which at least humans, various objects and a divinity are present, as well as actions, movements, statements, perceptions and various thoughts. I shall then try to use the word "ontology" on at least two different levels: on the one hand, to describe entities, the presence of which must be assumed if the situation is to remain consistent, and on the other hand, to focus on what really exists, beyond what people do and say. Finally, I will explore the advantage of this "realist" point of view.

Authors: Malik Abdul , Mohkumuddin Syed , Rahim Humaira , Hanif Shamima
Published: December 2020

Background: Proton pump inhibitors (PPIs) are in routine widely prescribed to hemodialysis patients. Recent studies have reported the association of PPIs use with hypomagnesemia in patients with long term hemodialysis. This study aims to determine the frequency of hypomagnesemia in patients of hemodialysis taking proton pump inhibitors.

Patients and methods: This cross-sectional study was conducted in the Department of Nephrology of Sandman Provincial Hospital Quetta from 01-6-2019 till 01-9-2019. A total of 120 patients (52 PPI users and 68 non-PPI users) who were on HD for more than 06 months were included. Data regarding age, gender, duration of hemodialysis and taking PPIs were collected. Determination of serum magnesium was made by taking 3 different samples at 2 weeks’ interval and the mean value of serum magnesium was calculated. Serum Mg2+ levels <2.0 mg/dL was taken as hypomagnesemia. A Chi-square test was applied to determine the association of PPI use with hypomagnesemia.

Results: Demographic variables such as age and gender were not significantly different between the groups. There was female dominance in both groups (73% in PPI groups and 66.1% in the non-PPI group (p-value 0.65). The mean duration of dialysis was 45.3±13.8 months in PPI users versus 48.9±12.9 months in non-PPI users (p-value 0.14). There was a significantly higher frequency of hypomagnesemia in PPI users; 36 (69.3%) versus 27 (39.7%) in non-PPI users (p-value 0.001).

Conclusion: The use of PPI is associated with a significant reduction in serum magnesium levels. So serum magnesium levels should be advised as routine monitoring in patients of hemodialysis taking PPIs.

Authors: Munawar Saira , Jafri Farhana , Qureshi Ahmad Farzad , Fatima Darab , Zahid Aliya
Published: December 2020

Background: Among the cervical vertebrae, atlas is known to have many variations, posterior ponticle being the commonest. It may completely or incompletely covers the groove of vertebral artery leading to ischemia of posterior circulation. Therefore, vertebral artery is at greater risk of injury during neurological and spinal surgeries. Prevalence of posterior ponticles varies widely among different populations, for instance in Turkish population it was 10.8%, in American 22.1%, Kenyan 14.7%, Brazilian and Indian 16.7%. The prevalence of lateral ponticle in Kenyan population was reported to be 3.9% and in Indians it was 2%. However, the data regarding the prevalence of these ponticles is largely lacking in Pakistan. Therefore, this research was designed to determine the prevalence of posterior and lateral ponticle in atlas vertebrae of Pakistani population.

Materials and methods: A total of 47 human atlas vertebrae of unknown age and gender from bone bank of Department of Anatomy Fatima Jinnah Medical University, Lahore were studied for the presence of complete and incomplete posterior and lateral ponticles. The bones studied were completely intact and did not have any pathology.

Results: Total incidence of ponticles was 38 % in this study, of which 36% were posterior ponticles and 2% were lateral ponticles. Bilateral incomplete posterior ponticles/were found in 8 (17%) atlas vertebrae whereas bilateral complete posterior ponticles/foramen arcuale were found in only 1 (2%) atlas vertebrae. Unilateral incomplete posterior ponticle was identified on right side in 5 (11%) and left side in 2 (4%) atlas vertebrae. Unilateral complete posterior ponticle was found in only 1 (2%) atlas on the left side whereas no such finding was identified on right side in any vertebra. Unilateral complete lateral ponticle was found in only 1 (2%) atlas on the right side but not on left side. No bilateral complete lateral ponticle and incomplete unilateral or bilateral lateral ponticles were identified in this study.

Conclusion: Presence of posterior and lateral ponticles pose a risk of vertebrobasilar vascular insufficiency and may cause variety of symptoms. Vertebral artery may be at risk during neurosurgical procedures when having a foramen arculae and may give a false impression of much wider posterior arch of atlas. Knowing the prevalence of this can help neurosurgeons, general surgeons, radiologists, and chiropractors in management of the patients.
Use of non-contrast computed tomography determined urinary stone fragility in predicting the outcome of extracorporeal shockwave lithotripsy treatment: a single-center study
Authors: Hameed Athar , Gondal Khazir Hayyat
Published: December 2020

Background: Renal stones represent a common urological pathology where standard treatment advised is ESWL in current practice. However, NCCT based determination of stone fragility may help to predict the outcome of ESWL treatment, hence optimizing its clinical use. Therefore, this study evaluated the role of NCCT determined urinary stone fragility in predicting the outcome of ESWL treatment in local clinical settings.

Patients and methods: One hundred patients with single renal calculus of 0.6-2 cm in size were included. NCCT based determination of stone fragility in HU units was done for all patients. Patients were then subjected to ESWL, with a maximum of 3000 shock waves given per ESWL session. Plain film and/or ultrasonography was used to monitor ESWL treatment progress with a final NCCT evaluation at 12 weeks to determine the clearance of the calculi for each patient. Association of NCCT based stone fragility and outcome of ESWL was statistically analyzed using Fisher exact test.

Results: The mean age of the patients was 37.7 ± 10.9 years with 54% being male. Decreasing stone fragility on NCCT (high = <500HU, moderate = 500-1000HU, and high = 1000HU) required more number and intensity of ESWL sessions (1-2 visits and 3000-6000 shock waves for high stone fragility group, 3-5 visits and 7000-18000 shock waves for the moderate group, and 6 visits and >18000 shock waves for low fragility group, respectively) necessary for clearance of urinary stones (p<0.001). In 98% of patients, the clearance of urinary stones was excellent.

Conclusion: Renal stone patients with NCCT determined high and moderate stone fragility show an optimal response after ESWL treatment, whereas, for low fragility renal stones attenuative treatment like percutaneous nephrolithotomy and/or ureteroscopy should be considered instead of ESWL. This approach can enable patient stratification before ESWL therapy ensuring better clinical management of the renal stone disease.

This
article examines the problem of legitimacy within the EU political system and
focuses on the political power and recognition of the only one directly elected
EU institution – the European Parliament. Historically, being the weaker
house of the EU legislative system, throughout the last decades, the
European Parliament has increased the political authority dramatically. These
political changes should have risen the participation of the EU citizens in the
elections and the legitimacy of this EU institution. Analysing the Lithuanian
case, based on the qualitative interviewing of politicians and quantitative
survey of citizens, the authors claim that while most of Lithuanians recognise
the significance of the European Parliament and the turnout in the European
elections has increased, the European Parliamentary elections remain, however,
of secondary importance.

Material were collected of two focus groups and it involved 13 leaders from different hospital management levels. Customer feedback information is collected simultaneously in several ways; oral feedback is not collected systematically. Customers provide feedback on service, care, friendliness and general hospital functioning. Customer feedback information is processed primarily by the unit attended by the customer. Physicians and nurses have a different role in customer feedback information processing. Hospital customer information processing is declarative and there is no uniform view on how to transfer customer feedback information between management levels. It is difficult to form a common conception of customer feedback information on the organizational level of this hospital

В статье рассматриваются действующие нормы Уголовного кодекса Российской Федерации, непосредственно направленные на борьбу с насильственным (незаконным) захватом государственной власти, а также нормы, которые формируют механизмы противодействия терроризму и экстремизму. Отмечается, что признак насильственного захвата власти на данный момент, помимо ст. ст. 278 и 279 УК РФ, встречается в структуре ряда составов ст. ст. 205.1-205.4, 205.6, 275, 280, 280.1, 282.1-3 УК РФ. На основании действующего законодательства насильственный захват власти относится к проявлениям экстремизма и терроризма. Автором анализируется эффективность имеющегося набора средств уголовно-правовой охраны основ конституционного строя, делается вывод об отсутствии в действующем УК РФ такого механизма уголовно-правового противодействия насильственному захвату власти, который бы позволял эффективно бороться с этим крайне опасным явлением на всех стадиях (этапах) его детерминации вне зависимости от формы осуществления государственного переворота. Предлагается развитие механизма уголовно-правового противодействия насильственному захвату власти, состоящего из комплекса взаимосвязанных и взаимодополняющих уголовно-правовых запретов, с учетом разнообразия проявлений и характера совершаемых действий.

The article examines the current norms of the Criminal Code of the Russian Federation, which are directly aimed at combating the violent (illegal) seizure of state power, as well as the norms that form the mechanisms for countering terrorism and extremism. It is noted that the sign of a violent seizure of power at the moment, in addition to articles 278 and 279 of the Criminal Code, is found in the structure of a number of compositions - art. 205.1-205.4, 205.6, 275, 280, 280.1, 282.1-3 Criminal Code of the Russian Federation. Based on current legislation, violent seizure of power is considered to be a manifestation of extremism and terrorism. The author analyzes the effectiveness of the existing set of tools of criminal law protection of the constitutional order, the conclusion about the absence in the current Criminal Code of the Russian Federation this mechanism of criminal legal counteraction to violent seizure of power, which would allow to effectively deal with this extremely dangerous phenomenon in all stages (stages) of its determination regardless of the form of the coup. It is proposed to develop a mechanism of criminal-legal counteraction to the forcible seizure of power, consisting of a set of interrelated and mutually complementary criminal-legal prohibitions, taking into account the variety of manifestations and the nature of the committed actions.

Poverty is a social problem that requires effective and sustainable management. Many parties have made various efforts to overcome poverty. However, the poverty reduction model that was built tended to only use a charitable approach. So that’s only creates a sense of dependence on aid. Poverty reduction requires the involvement of all elements of society, which in a systematic, sustainable, holistic and integrated manner. In line with that, the Islamic economic system offers an alternative in overcoming various socio-economic problems in society, through the instrument of zakah. Although many studies have found that the potential for zakah is very large, the collection and distribution of zakah funds has not been carried out optimally, so that it has not had a significant impact on poverty. Therefore, facing the current development, it is necessary to digitize the proper mustahiq economic empowerment model. The research type used is in the form of field research with a qualitative methods by conducting a deep review of various literatures. The research concludes that the proper digitalization of the mustahiq economic empowerment model can be carried out in a creative productive manner, by distributing a zakah that cannot directly used or spent by the mustahiq. So that the utilization of zakah itself, will have an economic impact on the mustahiq. In order to make this creative productive distribution model runs successfully, it requires coaching and mentoring activities. Coaching and assistance carried out for mustahiq must be adjusted with the era development, through the use of digital technology.
On modelling harmonic waves in linear micropolar elastic media by four screw fields
Authors: Радаев Юрий Николаевич
Published: December 2020

В статье рассматриваются дифференциальные уравнения для потенциалов, обеспечивающие выполнение связанных векторных дифференциальных уравнений линейной теории микрополярной упругости в случае гармонической зависимости поля перемещений и микровращений от времени. Предложена альтернативная схема расщепления связанных векторных дифференциальных уравнений микрополярной теории упругости для потенциалов на несвязанные уравнения первого порядка. Она основана на пропорциональности с разными масштабными факторами вихревых составляющих перемещений и микровращений одному вихревому винтовому полю. Найдено представление векторов перемещений и микровращений с помощью четырех винтовых векторов, обеспечивающее выполнимость связанных векторных дифференциальных уравнений линейной теории микрополярной упругости. В результате проблема нахождения вихревых составляющих перемещений и микровращений сводится к решению четырех несвязанных между собой векторных винтовых дифференциальных уравнений первого порядка с частными производными. Полученные результаты могут быть использованы в прикладных задачах механики, связанных с распространением гармонических (монохроматических) волн перемещений и микровращений вдоль длинных волноводов.

The paper is devoted to study of the coupled vector differential equations of the linear theory of micropolar elasticity formulated in terms of displacements and microrotations in the case of a harmonic dependence of the physical fields on time. An alternative analysis aimed at splitting the coupled vector differential equation of the linear theory of micropolar elasticity into uncoupled equations is given. It is based on a notion of proportionality of the vortex parts of the displacements and microrotations to the single vector, which satisfies the screw equation well known from the mathematical physics. As a result, the problem of finding the vortex parts of the displacements and microrotations fields is reduced to solution of four uncoupled screw differential equations of the first order with partial derivatives. Obtained results are to be used in applied problems of the micropolar elasticity and in particular in studies of harmonic wave propagation along waveguides

Получены наборы материальных и геометрических параметров силового поля DREIDING и балочного элемента, точно воспроизводящие механические модули графена в рамках стандартного метода ММ и метода МСМ. Эти методы реализованы в компьютерных кодах Pioner и MSC.Marc соответственно. Компьютерное моделирование частот и форм собственных колебаний однослойного графенового листа показало, что как частоты, так и соответствующие им формы собственных колебаний, полученные обоими методами, близки между собой, а также близки к частотам и формам колебаний почти квадратной сплошной пластинки, моделирующей ОГЛ.

Sets of material and geometric parameters of the DREIDING force field and beam element, which accurately reproduce the mechanical modules of graphene in the framework of the standard MM method and the MSM method, are obtained. These methods are implemented in computer codes Pioner and MSC.Marc, respectively. Computer simulation of the frequencies and modes of natural vibrations of a single-layer graphene sheet showed that both the frequencies and the corresponding modes of natural vibrations obtained by both methods are close to each other, as well as close to the frequencies and modes of vibration of an almost square continuous plate simulating a single-layer graphene sheet.

Рассмотрены максимальные напряжения в осесимметричных волнах в упругих стержнях для положительных значений коэффициента Пуассона. Обнаружена особая длина волны, для которой имеет место наибольшее значение максимального растяжения на оси по отношению к максимальному растяжению на поверхности. Показано, что и особая длина волна, и наибольшее значение отношений растяжений не зависят от коэффициента Пуассона.

The maximum stresses in axisymmetric waves in elastic rods for positive values of the Poisson’s ratio are considered. A special wavelength has been found for which the ratio of axial maximal extension to surface maximal extension has the largest value. It is shown that both the special wavelength and the largest value of the extensions ratio are independent of the Poisson’s ratio.
