Published: September 2022

The demand of energy utilization is increasing expressively as fast as the development of countries. Besides being available everywhere and virtual inexhaustible, renewable energy is undoubtedly necessary to avoid depleting the planet’s natural resources and global warming. Even considering the primordially environmental importance, the result of no emissions by renewable energy grant attractive also for political and economics statement.  It should be noted the sun is the most abundant primary energy source in the planet and essential for eco-friendly process like photosynthesis, wind action, water cycle as well direct uses as electric and thermal generations. Consequently, nowadays several methodologies have been applied in order to transfer energy between the cycle and its surroundings optimizing for instance the coefficient of performance and heat exchangers. An absorption system is widely applied in these cases due to supply a unique solution for a range of technological problems from solar cooling to steam-driven refrigeration. Alternatively, this article main objective is modulating an absorption refrigeration system (ARS) which uses water-lithium bromide as a working fluid. Therefore, using the software Engineering Equation Solver (EES) is possible to obtain a thermodynamic single effect code that allows elaborating parametric analyses. In other words, performed and verified the influence of some input parameters over other output parameters. First, it was necessary to consider the cycle operating as reversible and steady state. Furthermore, it is assumed that no chemical reactions occur between water and lithium bromide. Thus, in the meantime apply the heat exchangers and a Solar Collector to receive the thermal energy and provide to the refrigeration cycle. Similarly, water from external sources was used to change heat with the fluid water-lithium bromide. Satisfactory results were founded and it enable to calculate and evaluate all system heat transfers rates and coefficient of performance. Almost all of input parameters introduced brought adequate values over output parameters, but the most convenient were: mass balance of water-lithium bromide solution and temperature of cold water from outside source. Clearly, results always can be found but in conclusion this article can be used to verify parameters sensitivity, optimized absorption refrigeration solutions and supply knowledge for future applications.

Поскольку миграционная политика Российской Федерации должна быть направлена не только на снабжение экономики трудовыми ресурсами, но и на решение задач по обеспечению общественного порядка и безопасности граждан России, то особую важность приобретает противодействие нелегальной миграции, которая ухудшает криминогенную обстановку в стране и создает условия для теневой экономики и коррупции. Автор предлагает комплекс мероприятий, который позволит снизить уровень криминальной активности иностранных граждан, упорядочить миграционные потоки, будет способствовать формированию благоприятной миграционной ситуации.

The migration policy of the Russian Federation must be aimed not only at supplying the economy with labor resources, but also at solving the problems of ensuring public order and the security of Russian citizens. It is of particular importance to counteract illegal migration, which worsens the crime situation in the country and creates conditions for the shadow economy and corruption. The author proposes a set of measures that will reduce the level of criminal activity of foreign citizens, streamline migration flows and contribute to the formation of a favorable migration situation.
Features of the system of separation of powers in modern Russia during the constitutional reform
Authors: Багмет Анатолий Михайлович , Бычкова Екатерина Игоревна
Published: September 2022

Разделение властей является важнейшим инструментом демократии. Именно разделение властей создаёт необходимый баланс между существующими в стране органами власти и важные условия для взаимодействия государства и общества. В статье 10 действующей Конституции Российской Федерации закрепляется положение о том, что государственная власть в нашей стране осуществляется на основе разделения на законодательную, исполнительную и судебную ветви власти. Нормы Конституции закрепляют механизм гарантий самостоятельности каждой из ветвей власти и независимости при реализации ими своих полномочий. Принцип разделения властей на соответствующие ветви применяется в организации деятельности не только органов федеральной власти, но и органов власти в регионах нашей станы. В статье предпринимается попытка научного осмысления существующих проблем системы разделения властей и сдержек и противовесов в современной России, которые сохранились и были созданы в ходе конституционной реформы после поправок к Конституции в 2020 году. Авторы выражают точку зрения, согласно которой между ветвями власти необходим баланс и примерное равновесие, с целью более эффективного функционирования механизма государственной власти и государственного аппарата в частности.

Separation of powers is an essential tool of democracy. The separation of powers creates the necessary balance between the existing authorities in the country and important conditions for the interaction of the state and society. Article 10 of the current Constitution of the Russian Federation enshrines the provision that state power in our country is exercised on the basis of separation into the legislative, executive and judicial branches of government. The norms of the Russian Constitution establish a mechanism for guaranteeing the independence of each of the branches of government and independence in the exercise of their powers. The principle of separation of powers into corresponding branches is applied in the organization of the activities of not only federal authorities, but also authorities in the regions of our country. The article attempts a scientific understanding of the existing problems of the system of separation of powers and checks and balances in modern Russia, which were preserved and created during the constitutional reform after the amendments to the Constitution in 2020. The authors express the point of view that there is a need for balance between the branches of government, for the more effective functioning of the mechanism of state power and the state apparatus.

Authors: Ильюхов Алексей Александрович
Published: September 2022

Статья посвящена исследованию вопросов следственных (процессуальных) ошибок, возникающих в ходе производства по уголовным делам, которые в силу закона могут рассматриваться судом с участием присяжных заседателей. Анализируются объективные и субъективные причины, способствующие возникновению следственной (процессуальной) ошибки на различных стадиях досудебного производства. При этом делается акцент на том, что следственные (процессуальные) ошибки, допускаемые при производстве по данной категории уголовных дел, имеют стратегический, тактико-криминалистический, процессуальный и правовой характер, дается их правовая оценка и называются причины их возникновения. Отмечается наличие связи следственной (процессуальной) ошибки с профессиональным риском в работе следователя и предлагаются варианты его поведения, способные снизить возможность возникновения следственной (процессуальной) ошибки в ходе возникновении рискованной ситуации при выполнении следователем профессиональной деятельности. Методы: анализ, обобщение, сравнение, описание, системный анализ. Выводы: Следственные (процессуальные) ошибки по уголовным делам, которые в силу закона могут быть рассмотрены присяжными заседателями, носят стратегический и тактический характер. Следственные ошибки возникают по объективным и субъективным причинам. Эти же причины формируют явно обвинительный уклон в деятельности следователя - психологическую установку направить уголовное дело с обвинительным заключением в суд.

The article is devoted to the study of the issues of investigative (procedural) errors in criminal cases, which, by virtue of the law, can be considered by a court with the participation of jurors. The article analyzes objective and subjective reasons contributing to the emergence of investigative (procedural) errors at various stages of pre-trial proceedings. At the same time, the emphasis is placed on the fact that investigative (procedural) errors made during the production of this category of criminal cases have a strategic, tactical-forensic, procedural and legal nature, and their legal assessment is given and the reasons for their occurrence are called. It is noted that there is a connection between an investigative (procedural) error and an occupational risk in the work of an investigator and suggests options for his behavior that can reduce the possibility of an investigative (procedural) error during the occurrence of a risky situation when an investigator performs professional activities. Methods: analysis, generalization, comparison, description, system analysis. Conclusions: Investigative (procedural) errors in criminal cases, which, by virtue of the law, can be considered by jurors, are strategic and tactical in nature. Investigative errors arise for objective and subjective reasons. The same reasons form a clearly accusatory bias in the investigator's activity - a psychological attitude to send a criminal case with an indictment to court.

Published: September 2022

Our study was carried out to determine the control efficacy of sodium hypochlorite (NaOCl) for violet root rot caused by Helicobasidium mompa in apple. The experiment was conducted in the farm located at Chungbuk province in South Korea from 2014 to 2016. When infected apple trees were treated at least two or three times with 31.25 and 62.5 ml/l available chlorine content in NaOCl, it greatly increased the rooting of rootstock, and restored the tree crown density by 44.4-60.5%. In addition, the number of commercial fruit setting was increased by 54.3-64.5%, and the total starch content in shoots was significantly higher than other non-treated apple trees. However, the untreated disease control and thiophanate-methyl WP treated trees showed the symptom of dieback. Therefore, our results indicate that the drenching treatment of NaOCl with 31.25-62.5 ml/l available chlorine content more than two times from late fall to early spring could effectively control the violet root rot and recover tree vigor up to 60%.

Published: September 2022

Fake news has been in our lives as part of the media for years. With the recent spread of digital news platforms, it affects not only traditional media but also online media as well. Therefore, while companies seek to increase their own brand awareness, they should also protect their brands against fake news spread on social networks and traditional media. This study discusses a solution that accurately classifies the Turkish news published online as real and fake. For this purpose, a machine learning model is trained with tagged news. Initially, the headlines were analyzed within the scope of this study that are collected from Turkish online sources. As a next step, in addition to the headlines of these news, news contexts are also used in the analysis. Analysis are done with unigrams and bigrams. The results show 95% success for the headlines and 80% for the texts for correctly classifying the fake Turkish news articles. This is the first study in the literature that introduces an ML model that can accurately identify fake news in Turkish language.

Published: September 2022

Introduction: Venous disease comprises a range of conditions of varying severity, which can result in pain and discomfort and a reduced quality of life. The annual costs for the treatment and management of venous disease in the UK is in the order of billions of pounds. It is vitally important to direct finite National Health Service (NHS) funding into areas that will maximise health outcomes and reduce the burden on the NHS. To address the issue of where best to target resources and research, the Vascular Society of Great Britain and Ireland (VSGBI) in association with the James Lind Alliance (JLA) undertook a national Priority Setting Process (PSP) for vascular conditions. This paper presents the results of this process, with a focus on the topic of ‘venous conditions’. Methods: A modified JLA Priority Setting Partnership was developed to gather clinician, patient and carer research priorities for vascular conditions. Consensus workshops were held to discuss clinician and patient priorities and agree a list of joint research priorities. Consensus was achieved using the nominal group technique and a ranked ‘top 10’ list of research priorities for venous conditions was established. Results: In the first phase (clinician-led survey), 481 clinicians submitted 1,231 research questions related to vascular conditions in general. Of these, 130 venous-specific research priorities were reduced to 13 overarching summary priorities recirculated for interim scoring. In the second phase (patient and carer-led survey), 373 patients and carers submitted 582 research priorities. Of these, 101 venous-specific priorities were reduced to 22 overarching summary priorities and recirculated for interim scoring. In the third phase (consensus workshop), clinician and patient priorities were amalgamated into 14 priorities for discussion. The final ‘top 10’ list of venous condition research priorities relate to: access to specialist venous services, prevention, wound healing, pain management, education and compliance. Conclusions: The ‘top 10’ venous-related priorities demonstrate the research areas considered to be most important from the perspective of patients, carers and healthcare professionals. Researchers can now focus their efforts on developing research questions and studies to address these priorities and funders should increase their investment to support new studies in these areas of greatest importance.

Published: September 2022

The need to provide additional information towards adopting a well-developed and standard waste management scheme in Yenagoa Metropolis prompted this study. It was based on waste source, transferring process and stakeholders, location and elevation, ecological sensitivity, risk factors and general people’s wellbeing. The operation of waste stakeholders and their activities were recorded on daily basis through Mass-Volume Analysis method using weighbridge scale for twelve (12) months (January–December 2021); Student-T test (t) and Two-Ways ANOVA were used to analyzed results. Results confirmed that, Etelebou is a government approved open-air-dumpsite for both liquid and solid waste; the Brikari Nig. Ltd. Company is transferring 50% solid waste while the Patico and Saturday (21.8% each) merged top commuters transferring liquid waste to the central Dumpsite. In general, the open-air-dumpsite is receiving an average 546.830 tonnes of waste annually consisting of 91% solid and 9% liquid with less than 10% material recovery for reuse and recycling. At 5% (ά=0.05%) interval, the difference between weekly waste stream and wastes stakeholders (commuters) is insignificant (0.324<2.57); so also waste stream per monthly summary (0.32<2.14). We therefore discouraged the current dumping operation at Etelebou due to its elevation (5 meters below sea level), proximity to natural drainage with a porous geological structure that posses’ ecological health risk on flora and fauna. Therefore, the study advises alternative disposal site and recommends controlled incineration, compositing and waste recycling for best practice in low regions like the Niger Delta of Nigeria.

Authors: Tak Himangi , Gupta Ashok , Tak Himani , Agarwal Kamlesh
Published: September 2022

Gaucher's disease is a hereditary disease that can be diagnosed by determination of acid beta glucosidase enzyme activity on leucocytes but it's diagnosis is mostly delayed due to limited availability of test. The aim of the study was to determine prevalence of Gaucher's disease in patients of unexplained spleenomegaly and/or thrombocytopenia using dried blood spot filter test. This prospective cross sectional study was conducted after approval from Institutional ethical committee in 222 subjects, assuming 3.6% prevalence of the disease among unexplained cases of splenomegaly with 95% confidence interval, 0.05 α error, 80% power and with an absolute allowable error of 2.5%. After implementation of the diagnostic algorithm, samples from the patients were collected on dried blood pot filter paper and sent for analysis. Patients who tested positive by screening test were confirmed through mutational analysis done from the same sample. Data was expressed as mean, proportions and percentages. Mann Whitney test, Chi square test and Fisher's exact test were used for analysis. The prevalence of Gaucher's disease in our study population was 2.7% (CI 0.54 to 4.86) with the odds ratio for gender calculated as 3(95% CI 0.344 to 26.134). The results of this study show that the use of an appropriate diagnostic algorithm and DBS filter test facilitate early diagnosis and management of a rare disease, thereby saving a lot of medical resources while simultaneously improving the quality of life in patients.

COVID-19 outbreak has been declared pandemic by World Health Organization (WHO). This study was planned to know the current COVID-19 situation in district and to know the impact of data driven preventive strategy to curtail the cases (Between 3rd August and 2nd September 2020). This is a cross sectional study done in tribal district of Gujarat. Total registered patients upto 2nd September 2020 were included in the study. Out of total 1189 patients, 34.4% were female. Recovery rate on 3rd August 2020 was 44.8% which is increased to 82.09% on 2nd September 2020. Positivity rate declined from 5.2% to 2.3% despite increase in test per million from 5042 to 51606 between 3rd August and 2nd September 2020. This decrease in test positivity rate attributed to preventive strategy followed by district. Over a period of one month (3rd August to 2nd September) district observed gradual decrease in Compound daily growth rate (CDGR) and increase in doubling time. Over a period of time, downward trend in cases detection and increase in recovery rate observed due to preventive strategies followed by district. To curtail the COVID-19 it is required to keep constant watch on spread, as few cases left undiagnosed can make big spike in district.

Published: September 2022

The Intracerebral Hemorrhage (ICH) Score is commonly used in patients of ICH as a grading tool which assesses clinical outcome after ICH. It has undergone validation for 30 days mortality in various studies but data on its validation for long term outcome is limited. The aim of this study was to assess whether ICH Score accurately categorizes ICH patients with regard to mortality and functional outcome at 3 months. This was a prospective observational study which included patients reporting to emergency department of a superspeciality care hospital with acute intracerebral hemorrhage over one year period. Components of ICH Score and baseline parameters were recorded. The functional outcome was assessed using modified Rankin scale (mRS) at 3 months post ICH. Of the 70 patients included in the study, 42(60%) patients survived at 3 months and out of them 26(37.1%) patients had a good outcome on mRS scale at 3 months. The ICH score correctly stratified patients with respect to mortality and functional outcome at 3 months as assessed by dichotomous cut points along the mRS. To conclude, the ICH Score is a valid score used in intracerebral hemor-rhage for assessing mortality and functional outcome at 3 months.

It has been estimated that 4.4 billion individuals are infected with Helicobacter pylori and the prevalence of the infection varies globally ranging from the highest reported in Africa (70.1%) to lowest in Switzerland (18.9%). The prevalence is still abundant in developing countries and is due to the outcome of low socioeconomic status and poor sanitation. Helicobacter pylori infection is implicated in several pathological states and is confronting a gigantic challenge to the global health community. This review provides an extensive picture of Helicobacter pylori infection prevalence and its association with disease outcomes using myriad sample studies, emphasizing detection using gastric biopsy. Moreover novel molecular mechanisms unveiled to date are also presented to better comprehend the underlying events that triggers the epidemiological effects. Data and mechanistic pathways presented in this review aid in improved regulation of Helicobacter pylori infection and assists in designing and crafting new drugs to treat the associated clinical conditions.

This study was conducted to evaluate the attitude of radiography un-dergraduates in Sri Lanka towards artificial intelligence (AI) on medical imaging. An electronic questionnaire designed by Google forms survey administration software was used for data collection. The questionnaire consisted of different sections to evaluate demographic status of the participants, attitude, practice and knowledge related to AI on medical imaging. A total of 168 students responded to the questionnaire. The majority of them (64.3%) were female. Most of the respondents (92.3%) stated that they have practiced plain radiography imaging mo-dality during their clinical training. Around 67.9% respondents were aware about the AI based applications used in medical imaging. How-ever, the majority of respondents (51.17%) opined that AI will drastical-ly change and revolutionize medical imaging tools and methods in a foreseeable future. Most of the respondents (64.29%) believed that the use of AI based applications will make a radiographer’s duties more technical in the next 5-10 years. More than two thirds of the respond-ents (73.8%) stated their interest to involve any research on AI based techniques. In sub group analysis, there is a significant difference (p>0.05) of attitude between male and female respondents while no significant difference (p<0.05) of attitude between academic years. In conclusion responders showed a favorable attitude on AI which revolu-tionize medical imaging making radiographers duties more technical. It led to a strong demand to include AI technologies in both undergradu-ate and postgraduate training. Therefore, it is essential to take the lead in educating radiography undergraduate students about these emerg-ing technologies in the field of medical imaging and how to work effi-ciently with those technologies.

Onychomadesis is an idiopathic shedding of a proximal part of the nail as a result of the temporary suspension of a nail matrix function. It is seen in fingernails, toenails, or both. Various underlying causes like systemic illness, drug reactions, Viral diseases, and bullous diseases have been associated with Onychomadesis. However, the mechanism of any such association remains unclear. Here we present a case of On-ychomadesis and Beau lines in the fingernails of a 13-month-old girl following Hand, foot, and mouth disease.

Cervical lymphadenopathy is not a diagnosis but it is a sign or symp-tom. The etiology could be inflammatory or degenerative or neoplastic. Cervical lymph node evaluation plays a vital role in patients with head and neck cancers because the results determine the prognosis and choice of therapy. Ultrasonography can be used to assess the mor-phology, site, number, size and vascularity of cervical lymph node. However, the ultrasound criteria for metastatic lymph nodes are con-troversial. Sonoelastography is a novel imaging modality introduced as a non-invasive technique for evaluating cervical lymph nodes and to map the elastic properties of examined soft tissue. Neck lymph nodes are easily accessible and can be efficiently compressed against under-lying anatomical structures, with use of an ultrasound transducer for elastographic tissue characterization. The detail about the rigidity of a lymph node gives us the direction for percutaneous biopsy and nodal dissection under ultrasound guidance. Use of this information can also improve patient follow-up by enabling detection of cancer recurrence at an early stage. The study aims to differentiate benign and malignant cervical lymph nodes by observing the morphology, vascular Pattern and strain ratio cut-off value. In this trial 40 patients with cervical lym-phadenopathy were studied and the study concluded that Ultrasound elastography is a specific test unlike B-mode ultrasonography in dif-ferentiating benign and malignant cervical lymphadenopathy. The strain ratio cut-off value for benign vs malignant lymphadenopathy is 1.78. Thus Sonoelastography along with B-mode ultrasound increases the rate of detection of malignancy.
