This studyaims to treat kaolin synthetic wastewaterby using sludge from water treatment plant as a coagulant via the coagulation process. Water treatment sludge (WTS) was characterized by using Fourier transform infrared (FTIR), Scanning electron microscope (SEM), and X-ray diffraction (XRD). WTS had an amorphous structure and contained high aluminium metal constituents at 25.3%, which can be recovered as a coagulant. Acidification was conducted to recover the aluminium in WTS using sulphuric acid and produced water treatment sludge coagulant (WTSC). The optimum condition of WTSC prepared from WTS was evaluated through sludge concentration and acid dosage parameters. It has been observed that 0.5% sludge concentration acidified with 0.08 ml/ml sulphuric acid and normality constant at 0.5N was the optimum condition as it can remove turbidity at 99.5%. The performance of WTSC in the coagulation process using a standard jar test was studied based on the effect of pH and dosage of coagulant. The highest percentage turbidity removal (98.66%) was obtained at pH 12, kaolin turbidity was 117NTU, and WTSC dosage at 40mg/L. The percentage turbidity removal for alum and WTSC was almost similar. Thus, WTSC can potentially replace alum as a coagulant in water treatment plant (WTP).

Currently Elaies Guineensisor oil palm is the most widely planted commodity crop in Malaysiaand hasa very large impact to the country’s economy. At the same time, the industry also produces huge amount of oil palm waste materials such as Unripe FreshFruit Bunche (FFB).Each year million tons of Unripe FFB could not be processed in the mill and were disposed-off and thus posed additional threats to the environment. The objective of this study was to recycle the oil from Unripe FFB and comparedthe carotenoids content with the Ripe FFB. Carotenoids isthe natural chemical compounds which givespalm oil its orange red color. The compound is good for human health as it can strengthen body immunity system and act as antioxidantThe experiment was conductedby collecting fruits from three (3) samples of Ripe FFB and Unripe FFB. The selected fruits were then sterilized, and Crude Palm Oil (CPO) was extracted. The analysis of oil samples was conducted using Near Infrared Spectroscopy Diode Array (NIRS DA) 1650. Result for the carotenoids showed that mean for the Ripe FFB was 968.07 ppm and for the Unripe FFB was927.37 ppm. The Free Fatty Acids (FFA) were 22.08 and 14.47respectively which indicated that the fruits were badly bruised during the processing. This study showed that the carotenoids contentin Unripe FFB is comparable with the Ripe FFB and thus it canbe concluded that Crude Palm Oil (CPO) from Unripe FFB can be used for carotenoids extraction instead of rejected or disposed-off to the environment.

Published: January 2023

The article analyzes the main stages of the transformation of the British colonial administration, the process of transforming the system of relations between Great Britain and dependent countries that were part of the British Empire into the Commonwealth of Nations. The purpose of the research is to study the process of transformation of the British Empire, the formation of the Commonwealth of Nations and the role of official London in its formation and development. The methodological basis of the research are the principles of objectivity, historicism and systematicity with the application of general scientific methods of analysis, synthesis, generalization of logical and historical aspects, the study of phenomena in concrete-historical conditions, the transition from the concrete to the abstract and from the abstract to the concrete with the use of general scientific methods. The scientific novelty of the publication consists in a comprehensive analysis of the process of transformation of the British Empire into the Commonwealth of Nations, which convinces of the advantages of the peaceful transformation of multinational state entities over their spontaneous disintegration. Conclusions. A balanced and reasoned approach to the peculiarities of the state-territorial system in combination with stable traditions of democracy in the metropolis contributed to ensuring the asymmetry of the British imperial political body. Even at the end of the 19th century. at the first colonial and imperial conferences, the concept of the formation of all-imperial management structures - a common parliament, a common government, a common army, etc. was rejected. It was the lack of unification and asymmetry that formed the basis of the evolutionary processes that contributed to Great Britain in the 20th century to carry out the gradual formation of the "British Consensus" or "soft association" model.

Published: January 2023

The article attempts to analyze the role of the Arctic region in the foreign policy of Germany in the 20th century. It was revealed the influence of the internal political situation in the state on the manifestation of cyclicality in the use of certain mechanisms and tools for the implementation of foreign policy initiatives in the Arctic. At the end of the 19th and at the beginning of the 20th centuries, Germany actively used scientific researchers in the Arctic, which were introduced in the initiation of the International Polar Year (synchronous meteorological research in the Arctic) and participation in a number of international expeditions to the region. After the First World War, the Weimar Republic continued to participate in international polar research, but in the form of technological modernization of expeditions during the Second International Polar Year, which allowed the state to emerge from international isolation. Internal political changes in Germany with A. Hitler coming to power, contributed to the formation of the Arctic as a strategic direction of the Third Reich’s foreign policy during the Second World War – the occupation of the Arctic states (Norway, Denmark) and the use of their territory and the Arctic in the “weather war”. Cyclicality in Germany’s foreign policy regarding the Arctic was manifested with the return of a part of divided Germany, namely, West Germany, to participation in international scientific cooperation in the region during the Cold War era. The author came to the conclusion that the basis of Germany’s foreign policy initiatives in the 20th century, its active participation in international cooperation in the Arctic in the scientific and technological spheres contributed to the involvement of Germany, already united within modern borders, to the existing multilateral institutions of cooperation in the region.

The purpose of this study is to determine the distribution and features of sympathetic innervation of the tissues of the human colon wall in chronic slow-transit constipation using immunohistochemical methods. Materials and methods. Immunohistochemical study of large intestine segments (colon and sigmoid colon) obtained as a result of surgical treatment of patients with chronic slow-transit constipation was carried out using neural markers (PGP 9.5 protein, tyrosine hydroxylase, synaptophysin). Results. It has been shown that the majority of postganglionic sympathetic nerve fibers are localized in the Auerbach and Meissner plexuses. Their terminal axons form pericellular synaptic apparatuses around cholinergic neurons. Another part of the sympathetic fibers is involved in the innervation of the muscular plate of the mucous membrane and the walls of the venous vessels of the submucosa; their terminal varicose axons can be seen on smooth muscle cells as distant synapses en passant. Significant features of sympathetic innervation disorders of the large intestine of the studied patients were established; morphological evidence for the reactive, dystrophic and degenerative changes in the sympathetic apparatuses in the ganglionic plexuses were found. The regularities of the absence of sympathetic innervation in two muscle layers (longitudinal and circular), as well as in the mucous membrane, were revealed. Sympathetic neurons were not found in the studied sections of the large intestine. Conclusion. It is assumed that the identified pathological changes in sympathetic innervation in chronic slow-transit constipation can serve as one of the main causes of disruption of normal bowel functions.

Authors: Lychkova A. E. , Terentiev A. A. , Puzikov A. M.
Published: January 2023

Aim - to evaluate the effect of exogenous serotonin on the motility of the bauhinian valve and to identify the mechanism of this effect. Materials and methods. The experiments were performed on 36 Wistar rats weighing 250-270 g. The motor function of the ileum, ileocecal region, and caecum was recorded in the animals of two experimental groups (n=30). tonic contractions and propulsive activity. As a result of the study, it was shown that serotonin has a prokinetic effect on the ileum, the ileocecal junction with the Bauhinian valve and the caecum. 5HT3,4 receptors are located on the cytolemma of intramural serotonergic neurons and EC cells, and 5HT1,2 receptors are located on the cytolemma of effector smooth muscle cells. The Bauhinian valve contains the largest number of 5HT3,4 serotonin receptors, which is due to the complex function of this formation in the regulation of propulsive activity at the border of the small and large intestine.

The article introduces two clinical cases of successful treatment of Crohn’s disease (CD) of the upper gastrointestinal tract (UGT) with TNF inhibitors. Besides that, the article presentes the review, devoted to diagnostics and treat the same injury of patients with CD. It should be mentioned, that number of publications in worldwide and national literature is quite insignificant. One fact that is more important is the unavailability of unificational approach to treatment of such group of patients. We suppose that epidemiological research is necessary to define the true prevalence of lesions of the upper gastrointestinal tract in CD, risk factors and prognosis for this patient group, and to output the diagnostic and therapeutic tactics.

Published: January 2023

Despite the mass population immunization, the total spread of the COVID-19 pandemic once again made scientists around the world doubt the effectiveness of currently existing methods of prevention and treatment of a novel coronavirus infection. The rationale for a potentially new approach to the preventive therapy of COVID-19 using probiotic bacterial strains was the presence of a bidirectional “gut-lung” axis, which interacts between these organs through transported soluble microbial metabolites in blood. The study aimed to determine the relationship between the correction of the gut microbiota with the polycomponent synbiotic Maxilac® and clinical and laboratory markers of the severity of the new coronavirus infection. During the open-label, prospective, observational study 60 patients with a confirmed diagnosis of COVID-19, a moderate severity and the presence of gastrointestinal symptoms were divided into 2 groups: the 1st performed the outpatient complex standard treatment with the addition of synbiotic, the 2nd - without addition. All patients of group 1 showed positive dynamics of clinical and laboratory indicators of COVID-19 severity, compared with group 2, where 2 patients needed hospitalization due to the aggravation of the course of novel coronavirus infection. A reduction in the duration of clinical symptoms and the duration of outpatient treatment was revealed in a group of patients taking Maxilac®. The dynamics of clinical and laboratory indicators reflecting the course of COVID-19 indicate the effectiveness of symbiotic’s usage as adjuvant therapy and the possibility of recommending its use in the complex treatment of patients with a novel coronavirus infection.
Climate and health benefits of a transition from gas to electric cooking

Published: January 2023

Household electrification is thought to be an important part of a carbon neutral future, and could also have additional benefits to adopting households such as improved air quality. However, the effectiveness of specific electrification policies in reducing total emissions and boosting household livelihoods remains a crucial open question in both developed and developing countries. We investigated a transition of more than 750,000 households from gas to electric cookstoves - one of the most popular residential electrification strategies - in Ecuador following a program that promoted induction stoves, and assessed its impacts on electricity consumption, greenhouse gas emissions, and health. We estimate that the program resulted in a 5% increase in total residential electricity consumption between 2015 and 2021. By offsetting a commensurate amount of cooking gas combustion, we find that the program likely modestly reduced national greenhouse gas emissions, thanks in part to the country's electricity grid being 89% hydropower in later parts of the time period. Increased induction stove uptake was also associated with declines in all-cause and respiratory-related hospitalizations nationwide. These findings suggest that when the electricity grid is largely powered by renewables, gas-to-induction cooking transitions represent a promising way of amplifying the health and climate co-benefits of net-carbon-zero policies.
Leaving a plastic legacy: current and future scenarios for mismanaged plastic waste in rivers
Authors: Nyberg Bjorn , Harris Peter , Kane Ian , Maes Thomas
Published: January 2023

Mismanaged plastic waste (MPW) entering the riverine environment is concerning, given that most plastic pollution never reaches the oceans, and it has a severe negative impact on terrestrial ecosystems. However, significant knowledge gaps on the storage and remobilization of MPW within different rivers over varying timescales remain. Here we analyze the exposure of river systems to MPW to better understand the sedimentary processes that control the legacy of plastic waste. Using a conservative approach, we estimate 0.8 million tonnes of MPW enter rivers annually in 2015, affecting an estimated 84% of rivers by surface area, globally. By 2060, the amount of MPW input to rivers is expected to increase nearly 3-fold, however improved plastic waste strategies through better governance can decrease plastic pollution by up to 72%. Currently, most plastic input occurs along anthropogenically modified rivers (49%) yet these represent only 23% of rivers by surface area. Another 17% of MPW occur in free-flowing actively migrating meandering rivers that likely retain most plastic waste within sedimentary deposits, increasing retention times and likelihood of biochemical weathering. Active braided rivers receive less MPW (14%), but higher water discharge will also increase fragmentation to form microplastics. Only 20% of plastic pollution is found in non-migrating and free-flowing rivers; these have the highest probability of plastics remaining within the water column and being transferred downstream. This study demonstrates the spatial variability in MPW affecting different global river systems with different retention, fragmentation, and biochemical weathering rates of plastics. Targeted mitigation strategies and environmental risk assessments are needed at both international and national levels that consider river system dynamics.
Gender Identity in the 2021 Census of England and Wales: What Went Wrong?
Authors: Biggs Michael
Published: January 2023

The 2021 Census of England and Wales was the first in the world to elicit information on gender identity from an entire population. This paper argues that its results are implausible on the dimensions of geography, education, ethnicity, and religion. The results contradict external sources of data such as referrals to gender clinics and signatures on a pro-transgender petition. The results are also internally inconsistent when the various categories of gender identity are correlated across geography, and when compared to the results for sexual orientation. The spurious results were produced by a badly flawed question on gender identity, which was originally formulated by a transgender campaigning organization. The question evidently confused a substantial number of respondents who erroneously declared their gender identity to differ from their natal sex. Confusion is manifested by the overrepresentation of people lacking English proficiency or educational qualifications in the most suspect gender categories. These findings demonstrate how a faulty survey question can systematically distort our apprehension of the social world.

Authors: Karmacharya Ranjita , Thapa Nirupa
Published: January 2023

Introduction: The number of senior citizens in the world is growing rapidly so life satisfaction is the best indicator for evaluating successful aging. The aim of the study was to assess life satisfaction among senior citizens in Pokhara metropolitan city.
Methods: This community-based cross-sectional study was conducted among 325 samples from 17 cluster of Pokhara metropolitan city. Life satisfaction were measured through life satisfaction index-A. Descriptive statistics and inferential statistics were computed at a 5% level of significance. Study participants were aged 60 years and above, residing permanently in the study sites. Wards, households, and respondents were selected randomly. Data were entered in Epi Data and analyzed using statistical package for the social sciences 16.0 version.
Results: Findings revealed that 53.5% respondents were not satisfied with their life. Likewise, age below 70 (52.4%), male respondents (53.7%), senior citizens (60+) living with partner (50.8%) were more satisfied. In multivariate analysis pension (OR=0.482, CI=0.248, 0.935), sufficient money for expenditure (OR=2.370, CI=1.362, 4.123), family income (OR=4.391, CI=2.019, 9.551), state of health (OR= 0.464, CI= 0.215, 0.923) and role in family decision making (OR=2.001, CI=1.055, 3.793) were positively associated with life satisfaction.
Conclusions: More than half of the senior citizens were dissatisfied with their life. Financial state, state of health and role in family decision making are the main determinant factors of life satisfaction. Therefore, the authority body needs to be developing proper old age policies to resolute the socioeconomic problems of old people.

Published: January 2023

Introduction: Tonsillectomy is one of the most common surgical procedure in the world performed by Ear, Nose and Throat surgeon. Over the past decade, there has been progress in surgical techniques for tonsillectomy, yet pain and bleeding after tonsillectomy remain important surgical complications. With the increasing need to reduce healthcare costs in developing countries, there is currently a trend towards performing tonsillectomy on a daycare basis and this study aims at evaluating how efficacious it may be in our setting.
Methods: A retrospective review of all the daycare tonsillectomy surgeries performed at the Pokhara ENT Center, Pokhara, Nepal from February 2018 to January 2019. Patients aged 15 years and up of either sex who met the paradise criteria were included while patients who met the same but had a contraindication for tonsillectomy surgery were excluded. Demographic information as well as complications within six hours of surgery before discharge and on follow-up on the seventh post-operative day were evaluated, as were any emergency room visits in the first 24 hours and any complications requiring a visit to a healthcare facility.
Results: On day of surgery 17% had worst pain and on seventh post-operative day 75% had no pain, only 2% presented with primary hemorrhage and 3% presented with secondary hemorrhage. None of them required revision surgery.
Conclusions: Daycare tonsillectomy is being done in only some of the centers owing to the risk of postoperative complications in our country. In our study, the number of complications was lower and not life-threatening. It can be considered a safe and cost-effective method, though patient selection is crucial.

Published: January 2023

A buildup of plaque that contracts arteries and decreases blood flow to the heart causes chest pain, difficulties in breathing, or another coronary artery disease, medically called stenosis puts our lives at risk. We have used Navier-Stokes equations in a cylindrical polar coordinate system to study this problem by considering the flow is steady, axially symmetrical, fully developed, and laminar. Flow parameters like velocity profile, pressure drop, shear stress, and volumetric flow rate in the stenosed regions are analyzed after getting analytical solutions. We have focused our study to know the effect of the thickness of the stenosis in different parameters and the effect of the viscosity coefficient on blood flow behavior.

Melanism has been reported in many mammals, but records of melanistic leopards in Nepal are very few and not systematic, even though common leopards are found throughout the country and are considered one of the most problematic carnivores. In this study, we gathered data on records of five melanistic leopards that were seen or caught close to the Kathmandu Valley. Out of the five, two were captured on camera by locals, two were records of animals that were found alive but suffered injuries and passed away in captivity, and one was a record of a dead animal. All of them were recorded close to human populated areas. It is unknown what causes a high occurrence of melanosis in leopards and why it frequently occurs close to the Kathmandu Valley. It is recommended to conduct a comprehensive analysis of their population, geographic range, and habitat.

El objetivo fue evaluar la calidad seminal y el resultado de los servicios entre octubre/98 y enero/99, en una granja porcina del sur de Uruguay (34º LS). Se analizaron 100 eyaculados de 6 verracos Large White (LW) y Landrace (LD) adultos, y 363 inseminaciones artificiales que dieron lugar a 242 partos. Se estudiaron los efectos del genotipo del varraco y la cerda, mes de servicio, y sus interacciones sobre el número de lechones nacidos totales (LNT) y vivos (LNV). Al analizar las características espermáticas también se incluyeron los efectos de las temperaturas (máxima: TM; mínima: Tm) y humedades relativas (máximas: HRM y mínimas: HRm) del mes de colecta y sus interacciones. Se observaron efectos sobre el volumen del eyaculado, la concentración espermática y anormalidades espermáticas. El volumen fue afectado por el mes del servicio (P=0.0149); la TM (P=0.0274) y la HRm (P=0.0506) afectaron negativamente, pero la Tm (P=0.0066) y la interacción TM*HRM (P=0.0412) afectaron positivamente. Las temperaturas afectaron negativamente la concentración (TM: P=0.0006; Tm: P=0.00044) y se observó una interacción entre ellas (P=0.0010). El mes también afectó la morfología (P=0.0548). El tipo genético del verraco afectó el tamaño de camada, LD>LW (P=0.0021). El mes de servicio afectó el porcentaje de parición (P>0.01). En conclusión, si bien para las (P=0.0021). El mes de servicio afectó el porcentaje de parición (P>0.01). En conclusión, si bien para las condiciones de este ensayo, la calidad seminal entre los meses de octubre a enero no parece ser un factor limitante del tamaño de la camada; se confirma el efecto estacional sobre la fertilidad del cerdo en nuestro país.
ОБРАЗ «РАДЯНСЬКОЇ ЛЮДИНИ» У КОНТЕКСТІ ПРОБЛЕМИ ДВОМОВНОСТІ В ПЕРІОД «ЗАСТОЮ»
Authors: Демуз Інна , Січкаренко Галина
Published: January 2023

У статті висвітлюються ключові методи трансформації мовно-культурних цінностей особистості, перетворення її у «радянську людину» у контексті проблеми двомовності періоду «застою». Визначено основні причини й наслідки впливу політики русифікації на формування нової особистості, її моделі поведінки і самоідентифікації. Це був визначальний крок у розбудові нової наднаціональної спільноти «радянський народ» у контексті проголошеного курсу на «злиття націй». Доведено, що мовна політика мала значний ефект на розвиток самобутності населення Радянської України і стала важливим методом формування радянської людини. Встановлено, що поряд з русифікацією суспільства радянська влада використовувала й інші інструменти формування нового світогляду населення. Особливо ефективно вони втілювалися через засоби масової інформації. Використовуючи обґрунтовані радянськими ідеологами міфи, тези, ідеологеми, радянські медіа здійснювали своєрідне зомбування, нав’язуючи потрібні ідеї пересічним громадянам. У контексті реалізації курсу на «злиття народів» певні інформаційні повідомлення радянських ЗМІ формували комплекс меншовартості в окремих етнічних груп, що зумовлювало швидку зміну мовно-культурних традицій свого народу на нові радянські. З’ясовано, що телебачення і кіноіндустрія значно вплинули на формування особистості періоду «застою». Російськомовний кінематограф поступово заполонив ефірний час. Через низку чинників українське кіно не мало змогу повноцінно конкурувати з російським. Визначено, що так зване «виховання мас» відбувалося ще зі шкільних років. Особливо активно впроваджувалася антирелігійна кампанія і русифікація. Розкрито значення ідеологічного обґрунтування місця жінки в радянському суспільстві в контексті формування образу «радянської людини». Чільне місце в контексті трансформації світогляду населення мав розвиток радянської обрядовості. З’ясовано, що радянська політика у галузі культури мала негативні наслідки, оскільки суттєво вплинула на етнодемографічні процеси, деформувала ідентичність окремих категорій населення, які не сприймали мовно-культурних і національних особливостей державотворення України від моменту проголошення незалежності.

Published: January 2023

In the context of the development of physical education, there is a problem of formation of ideas about nanotechnology of students of general secondary education, which requires its thorough research. The methodology of the research includes the analysis of legal documents, psychological and pedagogical literature and scientific research to determine the essential characteristics of the main concepts, such as: «perception», «perception of nanotechnology»,«perception of nanotechnology of students of general secondary education». It was found that representations are divided into two groups depending on the impact on the subject's sense organs and perform signaling, regulatory and tuning functions in its implementation. They begin to function in a problem situation, which can have varying degrees of certainty, helping to predict the consequences of an event, solve complex problems, rationally evaluate circumstances, search for cause-and-effect relationships, and act in an environment with incomplete information. The interpretation of the terms with the prefix «nano-», in particular «nanotechnology», which in the general sense is defined as the influence on matter at the level of individual molecules and atoms, is given. It has been established that nanotechnologies provide an opportunity to create and modify nanomaterials in a controlled manner, as well as to integrate them into fully functioning larger-scale systems. Thus, the main task of nanotechnologies is to obtain nanomaterials with a given structure and properties and their use for a specific purpose. Emphasis is placed on the need for students of general secondary education to realize the role of nanotechnology in science, production and various spheres of human activity, which leads to the activation of imagination as an important cognitive process. The possible ways of forming ideas about nanotechnology among students of general secondary education are highlighted: updating the content of physics regarding the physical properties of nanomaterials and the use of nanodevices; coverage of historical facts that lead to changes in the perception of the physical picture of the world; implementation of a separate course on nanotechnology, etc. Key words: students of general secondary education, nanotechnology, imagination, physical education.

The article examines the possibilities of using new information technologies in the professional activity of a subject teacher, with the aim of improving various approaches to learning, focused on the development of the student's intellectual potential in the conditions of distance education. Competence - includes a set of interconnected qualities of a person (knowledge, abilities, skills, methods of activity) that are set in relation to a certain range of subjects and processes and necessary for high-quality productive activity in relation to them. Competence is a person's possession of appropriate competence, which includes his personal attitude towards it and the subject of activity. Competency approach is an approach that focused on the result of education, and the result is not the amount of information learned, but the ability of a person to act in various problem situations. In our work, we focused on the issue of formation and development of informational competence of subject teachers. By the information competence of the subject teacher, we will understand not only the use of various information tools, but also their effective application in pedagogical activities in the conditions of distance education. According to the new regulation on certification, if a teacher does not own a computer, he cannot be certified to the first or higher category. To increase the level of the teacher's information competence, it is recommended to: participate in seminars of various levels regarding the use of new information technologies in educational practice; participate in professional contests, online forums and forums; use a wide range of digital technologies and tools (text editors, image processing programs, presentation preparation programs, electronic spreadsheets) in preparation for lessons, electives, and project activities; ensure the use of Internet resources; form a bank of educational tasks that are performed with the active use of new information technologies; to develop own projects regarding the use of new information technologies in the conditions of distance education. It is also considered how the use of new information technologies facilitates the activity of the teacher in conducting classes. Possibilities of using new information technologies at all stages of conducting a modern lesson in the conditions of distance education. Key words: new information technologies, information competence, multimedia presentation, distance education.
