Evidence that residues of tebuthiuron arboricide present in soil of Mokala National Park can be phytotoxic to woody and grass species
Authors: Reinhardt Carl F. , Bezuidenhout Hugo , Botha Judith M.
Published: March 2022

Mokala National Park (MoNP) has a history of arboricide use through South African National Parks (SANPs) having bought commercial game farmland for its establishment in 2007. Tebuthiuron arboricide is known to have been applied for controlling bush densification during the period 1996 to 2004. Persistent negative impacts on MoNP vegetation, which are ascribed to the historical arboricide use, have prompted this investigation from 2016 to 2017. Bioassay experiments employing as test plants the tree species Vachellia erioloba and Vachellia tortilis, the shrub species Senegalia mellifera and the grass Tragus berteronianus were conducted in a glasshouse. Growth responses of these species were assessed upon their exposure to a tebuthiuron concentration range that simulated expected levels in MoNP soil soon and long after application. Chemical analysis as well as bioassay with the test species Lycopersicon esculentum (tomato) were performed on soil samples collected from three depths (0−30, 30−60 and 60−90 cm) of the soil profile at two sites in MoNP where tebuthiuron was applied in the past. The three woody test species showed differential, negative growth response to tebuthiuron, and even growth of the grass species (T. berteronianus) was affected at the higher concentrations. Evidence provided by the tomato bioassay and analysis performed on soil samples collected in situ points to the putative presence of tebuthiuron, more than a decade after the last use of arboricides for controlling bush densification.Conservation implications: If the reported evidence of the presence of phytotoxic residue of tebuthiuron in soil of MoNP would be substantiated through further research, such findings could at least partly explain the failure of natural recruitment of vegetation in those areas where the woody component was degraded because of arboricide application more than a decade ago.

Published: March 2022

Effective risk communication is essential for outbreak mitigation, as recently highlighted during the coronavirus disease 2019 (COVID-19) pandemic. Hand hygiene is one of the proposed public health interventions to protect against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) acquisition and transmission along with social distancing, improved ventilation, environmental cleaning, and wearing of masks. Improving hand hygiene practices in the community requires an understanding of the socio-behavioural context. This cross-sectional community survey in Soweto identified gaps in hand hygiene, which can inform appropriate messaging at the community level. Only 42% of survey respondents practiced adequate hand hygiene. Tailored educational messaging should be targeted at young adults in particular, and the importance of soap for hand hygiene must be emphasised for all age groups. Risk communication should expand to focus on preventing multiple infectious diseases during and beyond the COVID-19 pandemic.
An audit of the adequacy of contrast enhancement in CT pulmonary angiograms in a South African tertiary academic hospital setting
Authors: Basson Derik J. , Moodley Halvani
Published: March 2022

Background: Undiagnosed pulmonary embolism carries high mortality and morbidity. Computed tomography pulmonary angiogram (CTPA) is the diagnostic method of choice for accurate diagnosis. Inadequate contrast opacification is the second most common cause of indeterminate CTPAs.Objectives: Audit the adequacy of CTPA contrast enhancement and determine whether inadequate enhancement is affected by the size and site of the intravenous cannula, flow rate, contrast volume, contrast leakage and day shift versus after hours services.Method: Retrospective and prospective audits of the adequacy of contrast enhancement of CTPAs at the Charlotte Maxeke Johannesburg Academic Hospital were conducted using the Royal College of Radiologists guidelines (≤ 11% of studies with 210 HU). Protocol variables were collected prospectively from questionnaires completed by radiographers performing the CTPAs. Adequate versus inadequate groups were analysed.Results: A total of 63 (retrospective) and 130 (prospective) patients were included with inadequate contrast enhancement rates of 19% (12/63) and 20.8% (27/130), respectively. The majority of CTPAs were performed during the day 56.2% (73/130) with a 20G cannula 66.2% (86/130) in the forearm 33.8% (44/130) injecting 100 mL – 120 mL contrast 43.1% (56/130) at 3 mL/s 63.1% (82/130). The median flow rate (3 mL/s) and contrast volume (80 mL) were identical in both adequate and inadequate groups, while the remaining variables showed no statistical difference.Conclusion: The rate of inadequately enhanced CTPAs in this study was high. The protocol variables did not have a significant influence on the rate of inadequate enhancement. Further research, particularly using flow rates 4 mL/s, is required for protocol optimisation.
Selection of the most appropriate interpolation method for sandstone reservoirs in the Kloštar oil and gas field

The distribution of porosity data collected at the Kloštar field is analysed. This field is located in the north-western part of the Sava depression, and represents one of the most long-standing fields with respect to oil production in Croatia, where production has been ongoing for more than 50 years. Several reservoirs of very diverse lithology and stratigraphic age have been discovered. The oldest reservoirs (with minor oil reserves) occur in basement rocks of the Tertiary system (informally named the „temeljno gorje";;), then in Badenian coarse-grained clastics, as well as sandstones of Pannonian and Pontian ages. Major reservoirs, with respect to size, number and volume, are located in sediments of the Upper Pannonian and Lower Pontian. These are medium-grained sandstones, mostly quartz-mica grains, mutually separated by marls. Reservoirs of Lower Pontian age occur within whole structures (anticlines) at Kloštar, while the Upper Pannonian has been developed only in the south-west part. Earlier studies on the reservoirs have included only several measured values of reservoir porosity. These values have not been mapped, but only a unique average value, characteristic for the whole reservoir was calculated. Reinterpretation of e-logs increased the number of input values to 20 points of data. Rules are determined for the distribution of porosities in the largest reservoir of the Lower Pontian named ";;T";;. These regularities can be translated to the other sandstone reservoirs. Several interpolation methods were selected (inverse distance, nearest neighbourhood and moving average), with special emphasis on kriging. The interpolated maps are different. Based on a comparison of isoporosity, lines, shapes, and cross-validation results, kriging was evaluated as the most appropriate method for porosity interpolation.
New findings of halimedacean algae from the Late Triassic Dachstein Limestone of the Northern Calcareous Alps (Hochschwab Area, Styria, Austria)
Authors:   University Leoben, Institute for Geosciences, Germany, Schlagintweit Felix , Pavlik Wolfgang ,   Geologische Bundesanstalt, Wien, Austria
Published: March 2022

Two taxa of halimedacean algae are recorded from the Upper Triassic lagoonal Dachstein Limestone (Norian-Rhaetian) of the Hochschwab area in the south-eastern part of the Northern Calcareous Alps of Austria. They are described in open nomenclature as Halimeda? sp. 1 and Halimeda? sp. 2. In contrast to the widespread occurrence of dasycladacean algae, representatives of Halimedaceans are very rare. These findings are the second record in the Northern Calcareous Alps since FLÜGEL (1975).
Palaeobiogeography of the genus Latochara (fossil Charophyta) in the Upper Jurassic of Southern Europe. New data from Oléron Island (France)

Published: March 2022

A charophyte assemblage including Latochara tenuicostata (PECK 1937) and Mesochara gr. voluta (PECK 1937) was found in the Lower Tithonian bone-bed 148 of the stratigraphic section at the Pointe de Chassiron, Oléron Island (Charente-Maritime, Southwestern France). This bed, which is well known for its rich and diverse fauna of tetrapods, was deposited in a margino-littoral environment of Purbeckian facies in the Late Jurassic Charente palaeogulf. The occurrence of Latochara at Oléron Island is the most southern location known in the distribution of this genus during the Late Jurassic. This suggests that the boundary between the charophyte Boreal and Tethyan provinces, defined on the basis of this distribution, is not solely determined by latitudinal (i.e. thermal) factors. Ecological factors such as salinity and competition with other charophyte families are hypothesized as alternative explanations.
Lithocodium and Bacinella signature of a late Hauterivian, local microbial event: the Urgonian limestone in South-East France
Authors: Conrad Marc A. , Clavel Bernard
Published: March 2022

Sediment binding crusts of Lithocodium aggregatum and associated Bacinella irregularis abound in a shallow water limestone layer, in South-East France. The sudden appearance of these crusts denotes a local, conspicuous change in the otherwise balanced, open marine depositional environment. Based on regional correlations, the layer is Lower Hauterivian, Ligatus Zone, directly dated by an assemblage of orbitolinids, and indirectly by a specimen of ammonite. It is older than the Faraoni OAE (latest Hauterivian, Angulicostata auct. Zone), and presumably not linked with a global climate change. Two facies are recognized: (1) Lithocodium bindstone, with Bacinella, other microencrusters, and fluorescent automicrite of microbial origin; (2) floatstones containing numerous fragments of Lithocodium and accompanying biota. Coarse rhomboedral dolomite is locally present. Two modern analogues of microbial mediation are put forward to explain the Lithocodium event: (a) Lagoa Vermelha, in Brazil, along with anoxic, marginal marine conditions; (b) Highborne Cay, in the Bahamas, along with oxic, open marine conditions. A stack of four, Upper Hauterivian parasequences is described: Parasequence 1 ends with oolitic deposits; the somewhat deeper water Parasequence 2 occurs only in the south-eastern part of the study area, towards the direction of the Subalpine depotcenter; Parasequence 3 matches the layer with Lithocodium and Bacinella, with wide thickness variations (0.8 m - 11 m), resulting from a syn-sedimentary tectonic activity in the area of a major feature, the Vuache fault system. Parasequence 4 finally corresponds to the resumption of the normal, Urgonian carbonate factory.

Published: March 2022

Izmirella cretacea nov. gen., nov. sp., a complex alga, forming microbioherms is described from Barremian - Aptian platform carbonates of the "Bornova block", an allodapic unit derived from the northern margin of the Menderes Massif, included in Maastrichian - Danian flysh deposits, the so called "Bornova melange". The verticillate thallus of this alga consists of strongly imbricated bowl- to funnel-shaped whorls having tightly stacked laterals with two layers. The first is composed of radially and fan-like running segments, appearing as large cells in section parallel to the growth direction. The second is composed of multibranched tubes, running perpendicular to the segments of the first layer. Besides its organizational traits, this has original calcite mineralogy and an aggregative behaviour leading to the formation of laminated buildups closely resembling stromatolitic bioconstructions or even stromatoporoids.
W kręgu Yukiguni. Język i sztuka pisarska Kawabaty Yasunariego

Published: March 2022

Trwająca niemal pół stulecia aktywność pisarska Kawabaty Yasunariego (1899–1972), pierwszego japońskiego noblisty, autora uznanych powszechnie na całym świecie wybitnych dzieł, takich jak przyswojone polszczyźnie Tancerka z lzu, Kraina śniegu, Tysiąc żurawi, Śpiące piękności, Głos góry czy Meijin – mistrz go, przypada na okres, kiedy historyczne doświadczenia Japonii obejmowały zarówno imponujące sukcesy, jak i dotkliwe porażki, entuzjazm duchowego otwarcia na świat, jak i próby nacjonalistycznej izolacji, pokojowy rozkwit, jak i agresywną ekspansję. Wobec wszystkich dramatycznych i przełomowych dotknięć losu, nie tylko w życiu kraju, ale też we własnej indywidualnej egzystencji, cieszący się autorytetem w japońskich kręgach literackich Autor starał się zachowywać spokój i równowagę, a świat literatury, estetyki i dawnej tradycji japońskiej był dla niego schronieniem w ucieczkach przed tym wszystkim, czego nie umiał bądź nie chciał akceptować. Kawabata w całej swojej pisarskiej spuściźnie może być odbierany jako liryczny piewca wędrówek, poszukiwań i niespełnień w życiu uczuciowym jednostki, jako autor prowadzący czytelnika przez świat poruszających pejzaży oraz własnych zaskakujących odkryć, dokonywanych okiem wrażliwego obserwatora miejsc i ludzi, korzystający często z prawa do narracyjnych niedopowiedzeń, zawieszonych na wpół pytań i paradoksów ukrytej strony zjawisk, a przy tym mistrz subtelnej aluzji literackiej. Przygotowany w środowisku naukowym japonistyki Uniwersytetu Jagiellońskiego tom studiów omawiających dorobek Kawabaty, walory jego sztuki pisarskiej i stylu, ma być w intencji redaktorów i autorów tekstów próbą wypełnienia zauważalnej od dawna luki w polskim dyskursie literaturoznawczym i zapoczątkowania wielostronnej debaty na temat dzisiejszej percepcji jego twórczości z perspektywy poetyki, estetyki i stylistyki literackiej oraz translatoryki i lingwistyki tekstu.
Nowoczesne. O syberyjskich miastach okresu radzieckiego
Authors: Nędza-Sikoniowska Kinga
Published: March 2022

Książka Kingi Nędzy-Sikoniowskiej jest dla polskiego czytelnika zainteresowanego tematyką miejską unikatową, interesującą i dobrze udokumentowaną pracą dotyczącą powstawania radzieckich miast zakładanych in cruda radice na obszarach Uralu i Syberii przy znaczącym udziale architektów pochodzących z Europy Zachodniej i Stanów Zjednoczonych. Autorka, odnosząc się do przykładu dwóch ważnych przemysłowych ośrodków – Magnitogorska i Nowokuźniecka – rekonstruuje proces powstawania nowych miast, wskazuje na złożone i wielowymiarowe relacje łączące industrializację i urbanizację, zleceniodawców i projektantów, władze i przyszłych mieszkańców. Za sprawą dwóch studiów przypadków uzyskujemy interesujący obraz wykuwania się nowoczesności i utopii, ścierania awangardowej wizji zbawienia zaklętego w cegle z realiami gospodarki niedoboru, urbanizacji uwikłanej w polityczne walki między zjednoczeniami przemysłu, lokalnymi władzami a moskiewską centralą. To nie tylko opowieść o urbanizacji: projektowaniu i wytyczaniu miast, ale także o kartografii – wyznaczaniu i tworzeniu Syberii jako konstruktu geograficznego, politycznego i społecznego.

Think Locally, Act Globally. Polish farmers in the global era of sustainability and resilience
Authors: Drąg Zbigniew
Published: March 2022

The monograph should be seen as an attempt to present changes affecting the category of family farm owners in Poland over the last 70 years, since the end of World War II. These changes brought significant social transformations, including the dismantling of the landowner class (who had large agricultural farms in their possession), moving the state border westward and changing the multiethnic Polish society into one close to ethnic homogeneity. The main goal of this reflection is to recount ways in which family farms coped with various unfavorable forces and factors in order to remain in operation. One could say that the entire study can be viewed as a manifestation of the well-known phrase that served as the title of the James C. Scott book (1990): Domination and the Arts of Resistance. The monograph presented here refers to these analyses stemming from another edition of sociological research, completed within the framework of the MAESTRO project financed by the National Science Center of Poland. The main goal of the project was to depict the functioning of agricultural family farms as the traditional sector of agriculture in Poland in the contemporary context of globalization processes. The farms were examined in terms of the principles of sustainable development as well as flexibility and resilience in reaction to various crises. The monograph is divided into four essential parts. The first part is devoted to the theoretical issues and methodological groundwork for the entire publication. The second part of the book aims to capture the changes that took place from 1994 to 2017, which was an adequate period to encompass the changes and metamorphoses that mostly happened as a result of two things: the regime transformation which began in 1990, and Poland’s accession to the European Union on May 1, 2004. The third part deals with the crucial issues of regional variations, mostly in regard to life strategies and strategies of operating agricultural farms. Finally, there is a fourth part which places the focus on select themes, such as rural lifestyles, food safety and security, farmers’ utilization of new computer and IT resources, and the potential for socio-political mobilization.
A text-immanent, narrative-critical and logotherapeutic reading of the book of Amos and the necessity of a scientific approach by its readers to prevent terror deeds
Authors: Masoga Mogomme A , Ras Johan M
Published: March 2022

A text-immanent and narrative critical approach to the Biblical book of Amos reveals that the prophet Amos had addressed the social injustices of his time. He addressed the issues of his day with the belief that it was the Lord God (Elohim) Almighty who had instructed him to do so. The leaders of the well-known terror groups, Al-Qaeda, Al-Shabaab, Boko Haram and the Islamic State (IS) are also addressing contemporary social issues that confront them with the belief that Allah (God) has prompted them to do so. While Amos had discovered meaning through what he had seen and what he had said about the Lord and his interventions, the terror groups find their meaning in jihad (holy war). The book of Amos confronts modern readers to take scientific contextual analyses seriously and it also makes them aware that believers need to do what is right without making use of any violence to effect some societal change. In contrasts to this, the jihadists’ interpretation of the Quran and their quest for a world under Sharia law are not in line with sound scientific contextual analyses and as a result led to unacceptable terror and violent deeds in practice – something that must be rejected at all costs.

Se estudió la pubescencia de cuatro genotipos de Phaseolus vulgaris L. que bajo condiciones de campo demostraron diferencias en la reacción al virus del mosaico dorado. Las hojas de los genotipos A-429, DOR-303, 27-R y PC-50 mostraron sólo dos tipos de tricomas sin glándulas. Estos tricomas son aciculares (en forma de aguja) y unciformes (en forma de gancho). Entre el haz y envés de las hojas de los cuatro genotipos evaluados hubo diferencias en densidad y tamaño de los dos tipos de tricomas. Los tricomas en las hojas de cada uno do los genotipos varían tanto en número como en tamaño según el tipo de hoja. La línea A-429 fue la de hojas menos pubescentes y con menos densidad de tricomas por centímetro cuadrado. La línea DOR-303 mostró un mayor densidad de tricomas unciformes, pero de menor tamaño. En la variedad PC-50 hubo más tricomas aciculares en el envés que tricomas unciformes. En términos generales, la variedad 27-R fue la de mayor densidad de tricomas y en la que con mayor regularidad se encontraron los dos tipos de tricomas.

Managed Cyber-Vigilantism: StopXam between Collaboration and Competition
Authors: Martyanov Denis S. , Lukyanova Galina V.
Published: March 2022

Digital vigilantism is one of the challenges of e-democracy. Many scholars recognize the threat of vigilantism to civil society. However, we believe it can also reinforce weak government institutions. We consider digital vigilantism as an alternative to e-participation tools. This study aims to determine a model of digital vigilantism in Russia based on the analysis of the social media activity of StopXam in the context of the development of alternative e-democracy institutions. Considering vigilantism as an example of an informal institution, we analyze vigilantism following Helmke and Levitsky typology. The case chosen for analysis is one of the largest Russian vigilant StopXam movement that can be compared with the government initiative Moscow Helper. To identify the model of digital vigilantism in Russia, we conduct a social network analysis in respect to five communities in Vk.com, a Russian social network: “StopXam”, “StopXam Moscow”, the official community of “Moscow Helper”, the unofficial community of “Moscow Helper”, the community of opponents of “Moscow Helper” application. The findings of this study suggest that vigilantism could be considered as an instrument of informal institutionalization, which can be used by political actors (primarily the government) as a tool for setting the rules of the game that correspond to established public values. The creation of groups that are ready to observe the general principles of the game’s rules and impose common values with only minor, occasional violations of the letter of the law is becoming a working model of managed vigilantism. This model tends towards the routine practice of vigilantism, which limits the potential for online mobilization.
Cyberfeminism as Science Fiction. Drawn in Japan
Authors: Afanasov Nikolai B.
Published: March 2022

In the 80’s representatives of the second wave feminist theory nurtured hopes that new technologies would become an effective instrument of liberating from binary oppositions of patriarchal culture. Donna Haraway saw the potential of social transformations in cybernetic technologies. The fusion of biological, mechanical and cybernetic was to have led to the emergence of new cyborg subjectivity. It should be capable of creating its own culture as well as a new world. Later this narrative would be widely criticized, but in this optimistic form it greatly affected science fiction of the period. The author makes an attempt to present the theoretical components of cyberfeminism as science fiction that engenders cognitive estrangement. Catchy images of cyborgs were born in the performative framework of cyberfeminist theory and popular culture. They continue to affect imagination to the present day. Japanese animation stood at the vanguard of this cultural process. The article considers the visions drawn in Japan as a narrative that represents historical evolution of cyberfeminism. The end of anime’s “golden age” meant the end of a thorough work with cyberfeminism in the language of popular culture. The findings of the study reveal that cyberfeminism is a part of general theory that has subsequently become a part of global discourse of a new posthuman subject. The article emphasises the other part of the phenomenon – cyberfeminist practice – that has successfully adapted to the modern world.
The main risk factors for the development of cerebral palsy in children

Published: March 2022

Introduction. Currently, worldwide the formation of cerebral palsy (CP) makes a great contribution to the gain in childhood disability prevalence. The goal is to conduct a comparative analysis of risk factors and the main causes of the development of CP in children living in the Belgorod region for the period from 2020 to 2021. Materials and methods. There were analyzed histories of two hundred two CP children aged from four months to seven years. Results. Spastic forms of the disease predominated in the structure of infantile CP. Significantly more often this pathology occurred in premature babies at an early age and children residing in urban areas. The most frequent risk factors for the onset of the disease were such pathology of pregnancy as chronic fetoplacental insufficiency and chronic intrauterine fetal hypoxia. Delayed psycho-speech development had a leading place among all manifestations of the central nervous system in CP patients is beyond doubt. An analysis of the causes leading to the onset of the disease showed that in most cases it is not possible to discriminate one of them, since a combination of several unfavourable factors is often noted during pregnancy and parturition. CP children require constant care from relatives, long courses of complex drug and rehabilitation treatment.
Race, Religion, and Slavery in Alonso de Sandoval’s S. J. De instauranda Aethiopum salute
Authors: Hofmeister Pich Roberto
Published: March 2022

One of the most significant works on black slavery written by a Catholic thinker in the seventeenth century was Alonso de Sandoval’s De instauranda Aethiopum salute (1627/21647), which both describes the traffic of African slaves to Latin America and offers different clues to understanding the emergence of an ‘ideology’ of black slavery, which, to a certain extent, justified that system inside the Roman Catholic Church and the Iberian world. At the same time, Sandoval made an attempt to set up ethical criteria for the slave trade and the relationships between masters and slaves in the everyday life of the South American colonies. I propose an analysis of Sandoval's work focusing first on the theological foundations invoked for the slavery of black people, second on legal and moral debates over the justification of the enslaved condition of Africans and of the slave trade, and third on the roles of ‘race,’ ‘racism,’ and ‘true religion’ in Sandoval’s arguments. Sandoval introduces peculiar language and descriptions that deeply devaluate dark-skinned persons in general and African black culture in particular, supporting an ideology of subjection.

Owing to the various social media networks and the resulting plethora of data, there is a continuous change in social network research. This change has its own advantages and disadvantages for mathematical and statistical modeling. In this paper, we provide a mathematical model for Text Analytics parameters used in social networks. Game theory is used as the main tool in this modeling, as it works effectively in a decision-making process. In order to obtain the payoffs of the game theory model, the intercept parameter of Regression Analysis is used. Also, the paper has provided the solution for the proposed model of Text Analytics parameters of the social networking sites viz. Facebook and Twitter.
A Case Report of Intraocular Radiotherapy with Strontium-90 for Juxtapapillary Retinal Capillary Haemangioma
Authors: J Navaratnam , N Eide , TP Bærland , B Rekstad , T Nilsen
Published: March 2022

Juxtapapillary retinal capillary haemangiomas are rare benign vascular tumors located adjacent to the optic disc. They may occur sporadically or in association with von Hippel-Lindau disease. Treatment modalities for juxtapapillary retinal capillary haemangiomas vary from observation to aggressive vitreoretinal surgery. A combination of different treatment modalities is often tried with modest success. We report a patient diagnosed with right-sided juxtapapillary retinal capillary haemangioma at the age of 36 in an amblyopic eye previously treated with patching and surgery. In 2013, at the age of 45 he presented with increasing shadow in his right visual field. The ophthalmological examination revealed a right-sided subtotal serous retinal detachment with 6.2×5.6×3.5 mm juxtapapilllary retinal capillary haemangioma and visual acuity of hand movements. He underwent vitreoretinal surgery, radiation of juxtapapillary retinal capillary haemangioma with intraocular strontium applicator and insertion of silicone oil, all in one session. We describe a novel treatment, the intraocular radiation with strontium. This can be applied in complicated cases where vitrectomy is necessary.

INCREASING THE ENERGY PARAMETERS OF THE MAINS SUPPLY BY ACTIVE RECTIFIERS IN THE COMPOSITION OF FREQUENCY CONVERTERS
Authors: Ganiev Rishat N.
Published: March 2022

The total power consumed by electrical loads from the electric mains consists of their two components – active and reactive. Most electric drives of modern industrial enterprises operate with a reactive power index of 0.7–0.8. This leads to increased consumption of full power, which increases the load on the mains supply. Modern electric drives are built according to the principle: power supply – rectifier – DC link-inverter – asynchronous motor. Full power consumption occurs at the junction of the “power supply-rectifier”, where the required active power factor of the converter device can be formed. The higher the active power factor, the lower the reactive component in the total energy consumed. Thus, the article proposes a solution to the problem of creating highly efficient converter devices for powering electric motors with the formation of the necessary power factor, since frequency-controlled electric drives of modern mechanisms in industrial enterprises are the main consumers of electricity, which have a significant impact on the state of the supply network. The article considers the possibility of increasing the power factor of the mains input of electric drives with two-link frequency converters based on active (controlled) rectifiers with current inverters and voltage inverters. New methods of control of active rectifiers based on the use of AC rectifiers on fully controlled thyristors GTO, GCT, as well as IGBT transistors with pulse width adjustment are proposed. The variants of the construction of these rectifiers and the results of modeling the proposed control methods are presented, confirming a decrease in the passive components of the mains current, and as a consequence, an increase in the power factor of the network input. The simulation results are performed in the MATLAB 10 program, and are the basis for confirming the method of increasing the active power factor at the network input of a controlled frequency converter with a two-link structure.
DETERMINATION OF THE DYNAMIC LOAD CAPACITY OF ROLLING BEARINGS BASED ON THE RATED TORQUE OF THE ELECTRIC MACHINE
Authors: Matyunin Aleksey N. , Romanov Roman A.
Published: March 2022

The purpose of the article is to describe the method of calculating the dynamic load capacity of the most loaded bearing of an electric machine at the stage of electromagnetic calculation. The proposed method allows to initially determine the dimensions of such parts of an electric machine as bearings and bearing shields. The article considers the calculation of electromagnetic and mechanical parameters of an electric machine on the basis of the machine constant. The transition from the machine constant to the mechanical parameters of the bearing is carried out through the plot of radial loads (reactions) acting on the bearings. The dependences of the length of the shaft end on the permissible torque of the electric machine in accordance with GOST are given for different types of load, different strength and hardness of the shaft material. This technique connects the mechanical and electromagnetic parameters of the machine, allows to perform elements of mechanical calculation at the early stages of development. To simplify the calculation method, some relative geometric parameters are introduced, depending on the type and series or model of the electric machine. The load capacity of the most loaded bearing of the magneto-electric motor 11DVM160 for driving oil pumping machines is calculated. The initial data for the calculation were information from the design documentation, the results of computer modeling of the magnetic field, as well as test results. As a result of the calculation, the value of the dynamic load capacity of the most loaded bearing corresponding to the calculated mechanical load is obtained. In practice, the inverse problem may be relevant – determining the electromagnetic moment and power of the designed electric machine according to the bearing parameters limited by the specified initial dimensions of the machine.

Background: In the absence of effective treatment, coronavirus disease (Covid-19) poses severe risks to public health. This study aimed to explore the knowledge, attitude, and practice towards the COVID-19 pandemic among healthcare workers.
Methods: An online approach was adopted to conduct a cross-sectional study from 1st to 31st October 2020 among Iraqi healthcare workers in Anbar Province, west of Iraq. A semi-structured and self-administered questionnaire was recruited to collect the data. The study tool contains four parts sociodemographic, knowledge, attitude, and practice assessment. Multiple Linear regression was performed to test the association between the dependent and the independent variables. SPSS version 16 was used to analyze the data, and the statistical significance level was considered at less than 0.05 p-values.
Results: A total of 209 health workers were included in this study. Most of the respondents (54.5%) were Doctors (Physician, dentist, and pharmacist), males (60.8%), married (74.2%), aged less than 45 years (53.1%), urban region (64.6%), with a monthly income of USD 400 and above (61.7%) and 75.1% of them perceived their health good. The mean knowledge, attitude, and practice level of participants were 14.43 (± 2.01), 27.68 (± 2.74), and 4.33 (± 0.97), respectively. In the regression analysis, doctors (P-value = 0.000) aged 45 years and above (P-value=0.008) and urban residents (P-value=0.007) were significantly associated with upper knowledge scores. Female gender (P-value =0.022) was significantly related to positive attitude scores. While married (P-value = 0.038), those with experience of 10 years and above (P-value=0.041) showed better practice.
Conclusion: The level of knowledge, attitudes, and practices of healthcare workers in Anbar Province was adequate. However, with the expected new waves of pandemics, the policy of continuous training to update healthcare workers is inevitable to control and prevention of COVID-19.

Authors:   HOD Internal Medicine Department, American International University West Africa, Cabrera Asmell Ramos
Published: March 2022

Behcet’s disease (BD) is a rare condition, considered as a variable vessel vasculitis with multi-system involvement, characterized by the triad of recurrent mouth and genital ulcers with eye involvement, also may involve joints, skin, central nervous system, and gastrointestinal tract with important heterogeneity among patients regarding demographic features and organ manifestations. BD has a worldwide distribution. However, it is observed commonly among populations living along the historic Silk Road.The etiology of the disease remains unknown, but the most widely held hypothesis of disease pathogenesis is that of a profound inflammatory response triggered by an infectious agent in a genetically susceptible host. Number of reported cases is inexplicably low in sub-Saharan region and especially lowest in West Africa where only few cases have been reported. The aim of this presentation is to announce the first case description of BD in Gambia as well as, to sensitize physicians, Internal Medicine residents and general practitioners in our sub region with the pattern of the disease, as only way to reduce the diagnosis time frame

Particel Swarm Optimization (PSO) is a form of population evolutionary algorithm introduced in the early 1995 by two American scientists, sociologist James Kennedy and electrical engineer. Russell. This thesis mainly deals with the PSO optimization algorithm and the methods of adaptive adjustment of the parameters of the PSO optimization. The thesis also presents some basic problems of PSO, from PSO history to two basic PSO algorithms and improved PSO algorithms. Some improved PSO algorithms will be presented in the thesis, including: airspeed limit, inertial weighting, and coefficient limit. These improvements are aimed at improving the quality of PSO, finding solutions to speed up the convergence of PSO. After presenting the basic problems of the PSO algorithm, the thesis focuses on studying the influence of adjusting parameters on the ability to converge in PSO algorithms. PSO algorithms with adaptively adjusted parameters are applied in solving real function optimization problems. The results are compared with the basic PSO algorithm, showing that the methods of adaptive adjustment of the parameters improve the efficiency of the PSO algorithm in finding the optimal solutions.
Moral Decadence in Nigerian Politics: A Philosophical Investigations
Authors:   Department of Philosophy, Nnamdi Azikiwe University, Awka, Mbah, PhD Anikpe Anthony
Published: March 2022

When Nigeria got her independence in 1960 there were high hopes that she would become one of the greatest nations in the nearest future. Those who made this prediction were not wrong because Nigeria has what it takes to become great. In terms of population, it is not just the most populous but also one of the most talented in the continent. In natural resources, very few countries in Africa can boast of the resources the country parades. However, when these endowments are placed side by side with development in the country, the result becomes discouraging. Currently, one may assert that Nigeria is or at the point of becoming the poverty capital of the world looking at the rate her citizens are fleeing to other countries in search of greener pastures. Using the method of documentation and conceptual analysis, this study examines why Nigeria has not been able to translate its potentials into development indexes. The investigation centres around two research questions: 1) what is the relationship between the lack of development in Nigeria and electoral malpractice and 2) is Nigeria’s inability to translate its potentials to development caused by executive abuse of powers. The paper discovered that moral decadence in the form of electoral malpractice and executive recklessness are the root causes of Nigeria’s political and economic backwardness. It recommended the formation of an enlightened populace who will not only reject but also fight these two ills through civil resistance as the philosopher’s stone that will save Nigeria.
