This experiment has studied the changes in the liver in sheep during experimental infection with fascioliasis. Sheep were infested with 300 adoliskaria and observed changes up to 142 days. At the ultrastructural level in animals with fascioliasis, destructive changes were found in the liver. In the nucleus, the number of nucleoli decreases or they disappear completely, fragmentation of heterochromatin occurs and the content of euchromatin increases. The karyolemma exfoliates from the nucleus, as a result of which the perinuclear space expands. Mitochondria swell, they are polymorphic, and have an electron-dense matrix. At the beginning of the invasion, their number increases, and then their vacuolization, destruction occurs, while under the action of anthelmintic drugs and fasciolus toxins, the structure of the endolasmic network first of all changes: its cavities expand, then fragmentation occurs. Ribosomes are sprayed into the cytoplasm of the hepatocyte. It should be noted that under the influence of hexichol, acemidophene and thiopagol in the liver, membrane structures change most significantly and undergo necrobiosis.

The main safety indicators of the new preparation VEIS-2, containing natural or chemically modified avermectins as an active ingredient, when exposed to the skin of mammals, intended to protect the downy feather raw material from keratophagous insects, have been studied. It has been established that the VEIS-2 compositions containing abamectin or avermectin B1a hemisuccinate as an active principle have a mild irritating effect on the conjunctival mucosa of the rabbit eye. With single and multiple applications on the skin, the above compositions do not cause such functional and structural changes in the skin as edema, erythema, cracks, desquamation. The presence of skin-resorptive and allergenic action in the compositions of the VEIS-2 preparation with abamectin or hemisuccinate avermectin B1a using the "test tube method" in rats, as well as using the reaction of specific lysis of leukocytes (RSLL), has not been established. It was shown that the VEIS-2 composition based on avermectin complex has a more pronounced local irritant effect on laboratory animals in terms of toxicity and allergenicity.

The presented article presented data confirming the antioxidant properties of ferulic acid, which is associated with inhibition of the intensity of lipid peroxidation in the body of day-old turkeys, expressed in a decrease in the concentration of its cytotoxic products formed at different stages of the peroxide cascade: isolated double bonds (IDB) by 1,2 times, diene conjugates (DC) 1,6 times (p<0,001,.1,1), triene conjugates (TC) and oxodienic conjugates (ODC) 1,4 times, Schiff bases (SB) 12,02 times compared to the control. This helped to optimize the central metabolic processes, in particular carbohydrate metabolism. The paper analyzes these changes, presents and explains their relationship with the increase in quantitative and qualitative indicators of young turkeys at the early stages of ontogenesis. Thus, the superiority of the experimental group over the control of hatching turkey poults was 0,01% (p<6,66), the hatchability of eggs was 8,23% with a tendency to an increase in live weight of individuals of day-old age by 0,5%, the score according to the «Pasgar» scales and «Optistart» by 0,05 (p<1,0) and 0,001 points (p<XNUMX), respectively.

Esta pesquisa teve como objetivo investigar as implicações da produção de biocosméticos para o desempenho econômico do estado do Amazonas. Para tal, de forma específica, foi descrita a produção de biocosméticos e verificada a sua relevância na composição da indústria de transformação amazonense.Isto posto, de forma a viabilizar os objetivos propostos por esta pesquisa, foram utilizados dados oriundos do Instituto Brasileiro de Geografia e Estatística (IBGE), bem como da Superintendência da Zona Franca de Manaus (Suframa), pertinentes ao período de tempo estabelecido entre 2010 e 2015. A partir desses foi ponderada a dimensão da contribuição da indústria de biocosméticos na esfera econômica amazonense, mostrando, por meio de gráficos e tabelas, o resultado da atuação desta no cenário regional. Quanto aos resultados, foi percebido que a bioindústria de cosméticos no Amazonas ainda apresenta dificuldades na produção em larga escala, consequência da baixa produtividade das matérias-primas utilizadas, visto que o cultivo desses insumos apresenta sazonalidade, como é o caso do açaí, da castanha e da copaíba. Além disso, a logística de transporte na região amazônica é outro fator que desincentiva a instalação de nova matriz econômica no estado por causa da dificuldade de escoamento da matéria-prima para a indústria de biocosméticos.

Fractures are one of the most common components in multiple and associated injuries. Fractures of the lower jaw are observed in 76%, of the upper jaw in 24%, a fracture of the zygomatic-orbital complex in 12%. The actual problem of modern traumatology is the violation of reparative osteogenesis with injuries combined with facial trauma. The duration of the consolidation of fractures is determined by the degree of microcirculation disorders in the fracture zone, changes in cellular and coagulation hemostasis and mineral metabolism. In this connection, increasing the effectiveness of treatment of fractures of the bones of the face on the basis of early diagnosis of vascular and hemostasiological changes is of great importance for practical health care.
Detecting near-tail current sheet formation using isotropic boundaries: lessons from global MHD.
Authors:   Saint Petersburg State University, Gordeev E.I.
Published: February 2021

A number of recent studies suggests an existence of magnetotail current sheet configurations with tailward Bz gradient during the growth phase of the substorm. Such configurations are especially interesting since they are potentially unstable for different types of instabilities and can lead to explosive reconfiguration of the magnetosphere. However, the observations are rare and ability to observe tailward gradients is very limited. Here we use the global MHD configuration with near-tail Bz minimum to investigate the regions with adiabatic and non-adiabatic behavior of energetic particles. Thus we estimate the locations of the isotropic boundaries for the modelled POES-type spacecraft flybys. We expect that the lessons learned from global MHD simulation may become helpful in exploration of non-monotonic tail current sheet configuration using observations on low-orbiting spacecraft.

Изучены и классифицированы быстропротекающие динамические процессы, возникающие в системе нейтральной атмосферы и ее ионизованной компоненты в верхней области F2 при воздействии на среду мощного электрического поля с амплитудой 50-100 мВ/м, иногда до 150 мВ/м. Сделан статистический анализ развития восходящих потоков плазмы из ионосферы в плазмосферу для различных геофизических условий. По данным доплеровских измерений на субавроральной ионосферной станции Якутск впервые обнаружены новые, ранее неизвестные, динамические явления во время развития поляризационного джета. Проведенное исследование горизонтальных и вертикальных скоростей дрейфов ионосферы выявило, что в периоды наблюдения поляризационного джета пик вертикальной компоненты скорости не всегда совпадает с пиком горизонтальной составляющей. Скорости горизонтального дрейфа плазмы составляют, в среднем, ~300–600 м/с (есть события со скоростями 900–1000 м/с). Скорости вертикальной составляющей дрейфа, также в среднем, составляют 30–50 м/с (есть события со скоростями 100–150 м/с). По результатам анализа наземных ионосферных данных установлено, что все события с развитием поляризационного джета над Якутском подразделены равномерно на 4 группы, где первая группа –это когда значения вертикальных скоростей в полосе поляризационного джета достигали максимума одновременно с горизонтальными скоростями. В двух других группах времена пиков вертикальных скоростей сдвинуты в обе стороны от реперного времени на ±1 ч, a в последнем случае вертикальные скорости имеют равнозначные пики по обе стороны от пиковых значений горизонтальных скоростей.

Published: February 2021

У статті висвітлено результати моніторингу розвитку професійної успішності майбутніх учителів у педагогічних закладах вищої освіти. На основі проведено опитування серед студентів педагогічних спеціальностей, виокремлено чинники професійної успішності та уявлення щодо особистісних якостей та компетентностей, які забезпечать успішність професійної діяльності вчителя.

Проведене тестування за методиками: рейтингова шкала професійних мотивів; «Мотивація професійної діяльності» (методика К. Замфір у модифікації А. Реан), «Методика аналізу мотивації навчання у ВНЗ» (Т. Ільїна), «Діагностика мотивації успіху» (Т. Елерс), «Методика діагностики особистості на мотивацію до уникнення невдач» (Т. Елерс), тест «Потреба в досягненні» (Ю. Орлов та ін.), «Методика дослідження цін¬нісних орієнтацій» (Ш. Шварц), «Діагностика рівня професійної спрямованості» (Т. Дубовицька), «Діагностика потреб у саморозвитку» (В. Маралов). Це дозволило встановити, що у студентів недостатньо сформовані уявлення та мотивація досягнення професійної успішності, немає відповідних умов у середовищі ЗВО для стимулювання студентів до професійного зростання у напрямі досягнення успіху професійної діяльності. Причинами цього є недостатнє розуміння значущості успішності для особистості, неусвідомленість суспільних та особистісних критеріїв успіху, невисокий статус та престижність професії вчителя у суспільстві тощо. Виявлені недоліки дозволили сформулювати рекомендаційні положення щодо забезпечення необхідних та достатніх умов розвитку професійної успішності майбутніх учителів у закладах вищої освіти, закцентувати увагу на подальшій розробці системи реалізації професійної успішності майбутніх учителів у ЗВО.

Published: February 2021

Drilling mud is a dense, viscous fluid mixture used in oil and gas drilling operations to bring rock cuttings to the earth's surface from the boreholes as well as to lubricate and cool the drill bit. Water-based mud is commonly used due to its relatively inexpensive and easy to dispose of. However, several components and additives in the muds become increasingly cautious and restricted. Starch was introduced as a safe and biodegradable additive into the water-based drilling fluid, in line with an environmental health concern. In this study, the suitability of four local rice flours and their heat moistures derivatives to be incorporated in the formulation of water-based drilling fluid was investigated. They were selected due to their natural amylose contents (waxy, low, intermediate, and high). They were also heat moisture treated to increase their amylose contents. Results showed that the addition of the rice flours into water-based mud significantly reduced the density, viscosity, and filtrate volume. However, the gel strength of the mud was increased. The rice flours, either native or heat moisture treated, could serve as additives to provide a variety of low cost and environmentally friendly drilling fluids to be incorporated and fitted into different drilling activity.

‘A man embedded in society’
Authors: Medalie David
Published: February 2021

This chapter explores the ways in which E. M. Forster’s Maurice and Alan Hollinghurst’s The Swimming-Pool Library (1988), while criticizing the oppression of homosexual men, both offer trenchant criticisms of aspects of the ‘social fabric’, including contemporary constructions of masculinity. They locate aberrance and even criminality within the texture and deep structures of society itself rather than in the homosexual men whom society abjures. Unlike Maurice, The Swimming-Pool Library – a novel imbued with Forsterian echoes – was able to engage more openly with its social and political context; unlike the repressed Maurice Hall, its protagonist, Will Beckwith, enjoys what seems to be a sexually liberated lifestyle. However, Hollinghurst shows that, despite this, there has been very little progress where the inclusion or ‘embedding’ of these men in the ‘social fabric’ is concerned. Reading the two works together suggests that unpredictability and reversals may lie within ostensibly straightforward literary lineages.
Fruit, vegetable, and starch mixtures on the nutritional quality of black soldier fly (Hermetia illucens) larvae and resulting frass
Authors: Fischer H. , Romano N.
Published: February 2021

The production of black soldier fly (Hermetia illucens) larvae (BSFL) is rapidly becoming a new method to convert food waste into a sustainable ingredient in terrestrial and aquatic nutrition while the by-product, called ‘frass’, can be used as a soil amendment. The growth and nutritional quality of BSFL and their frass is greatly influenced by the provided substrates. In this study, fruits, vegetables, starches and in their combination (mixture) were provided to BSFL for two weeks and afterwards their final weight and nutritional composition of the BSFL and frass were measured. The starch treatment produced significantly heavier BSFL compared to those in the fruit treatment. However, BSFL produced from starch had the lowest amino acid levels. The BSFL produced from vegetables had significantly higher crude protein and essential amino acids compared to all substrates, with the exception of histidine. Frass produced from vegetables had significantly higher nitrogen-phosphorus-potassium values compared to all others, with the exception of nitrogen in the starch and mixture treatment. This study showed that the use of vegetables produced BSFL and frass comparable to soybean meal and many organic fertilisers, respectively, and these could be valuable and sustainable resources for the agricultural industry.

Authors: Pastor Danilo , Arcos-Medina Gloria , Bonito Vanessa , Cepeda Jaime
Published: February 2021

The personalization of certain teaching processes produces improved learn-ing results. In the assessment of learning, there is a need to personalize the test items according to the learning styles of the students. This paper pro-poses the design of an adaptive application that generates personalized tests according to the students' learning styles. To facilitate the design of the proposed application, an ontology for creating personalized tests was de-signed based on the use of learning styles by means of applying the Methontology methodology. This ontology has a hierarchy of 3 levels, 9 first-level classes, 12 second-level subclasses, and 10 third-level sub-classes. The application was developed using the Primefaces framework and the Jena library to manage the ontology. At the end of the development stage, the usability of the application created was measured using the heu-ristic evaluation method based on the ten principles of Jackob Nielsen. The results obtained indicate that the application complies with the aforemen-tioned principles, earning a 94% usability rating. Consequently, it can be deemed a useful application for end-users

It examined the effects of MGHE Connect on the course letter grade, pass rate, retention rate, total score, and final exam score in addition to the proportions of having more A and B grades in the course. The study used a posttest-only control group design. The 95-student sample was selected by sampling four sections using a simple one-stage cluster method. Then two sections were randomly assigned as a treatment group (N=45), in which using MGHE Connect Chemistry was required to com-plete course assignments, quizzes, and tests, and the other two assigned as a con-trol group (N=40) in which students completed the course conventionally. The study used ordinal logistic regression, binomial logistic regression, and multiple linear regression. The study indicated that when controlling the effect of students' CGPA, there was no significant difference in the odds of having higher letter grades between the experimental treatment and control groups. Also, the experi-mental group did not significantly have a higher proportion of A and B grades compared to the control group. The course pass rates and the retention rates in both groups differed insignificantly. The total course score and the course final exam score did not differ significantly. The study findings of students' academic performance metrics in the study indicating no statistically significant positive ef-fect of the MGHE Connect on the student academic performance.

Developments in information and communication technologies enable more information services to be used in education applications. In this respect, it is important for educators to adopt technology, follow it closely and show a positive attitude towards technology in order to be able to use the developing technology in the classroom. Today, using technology is not a privilege but a necessity. Technological developments affect the structure and functions of educational institutions. For this reason, teachers are expected to integrate their lessons with technology in order to train individuals of the information society. This study aims to determine teachers’ views on the use of information and communication technologies in education. Mixed research method was used in the study including experimental dimension and qualitative research. A total number of 58 teachers participated in the study. Results of the study provided useful implications for teachers in developing the ability to work in the information and educational environment.
Intelligent Tutoring Systems, Learning and Cognitive Styles of Dyslexic Students
Authors: Rasheed-Karim Walifa
Published: February 2021

This paper discusses how teachers may not always be available for supporting students, especially if students live in areas which are relatively inaccessible or too time consuming for teachers to reach. An alternative is intelligent tutoring systems (ITS) offering learners course support. However, it is evident that learners with special educational needs (SEN) such as dyslexia, may not have the cognitive facility to progress at levels equivalent to their peers and so may require support in strategies in which they could grasp concepts. One way of helping students to learn would be to harness strategies of teaching in ITS. It is suggested that bringing students together with ITS using mnemonic strategies may be a way of helping students achieve. The paper discusses the benefits of using mnemonic strategies by dyslexic learners and ways in which mnemonics could be harnessed in ITS.

One of the common types of arrhythmia is Atrial Fibrillation (AF), it may cause death to patients. Correct diagnosing of heart problem through examining the Electrocardiogram (ECG) signal will lead to prescribe the right treatment for a patient. This study proposes a system that distinguishes between the normal and AF ECG signals. First, this work provides a novel algorithm for segmenting the ECG signal for extracting a single heartbeat. The algorithm utilizes low computational cost techniques to segment the ECG signal. Then, useful pre-processing and feature extraction methods are suggested. Two classifiers, Support Vector Machine (SVM) and Multilayer Perceptron (MLP), are separately used to evaluate the two proposed algorithms. The performance of the last proposed method with the two classifiers (SVM and MLP) show an improvement of about (19% and 17%, respectively) after using the proposed segmentation method so it became 96.2% and 97.5%, respectively.

Prostate cancer (PCa) is one of the major causes of death due to cancer in men. Conventional imaging modalities such as magnetic resonance imaging (MRI) provide locoregional status, but fall short in identifying distant metastasis. C-11 choline F-18 fluorocholine (F-18 FCH) has been shown to be useful in imaging of PCa. The present prospective study evaluates and compares the role of F-18 FCH positron emission tomography–computed tomography (PET-CT) with locoregional MRI and whole-body bone scintigraphy in PCa patients for initial staging and recurrence evaluation. This study included a total of 50 patients. Tc-99m skeletal scintigraphy, F-18 FCH PET-CT, and diffusion-weighted MRI of the pelvic region were performed within a span of 2–3 weeks of each other, in random order. For the primary site, core biopsy findings of the lesion were considered as gold standard. The kappa test was used to measure agreement between bone scintigraphy, F-18 FCH, and MRI. For comparing Tc-99m bone scintigraphy, F-18 FCH, and MRI, McNemar's test was applied. F-18 FCH PET-CT and MRI were able to detect primary lesion in all initial staging patients. The sensitivity and specificity of F-18 FCH PET-CT versus MRI were found to be 92.8% versus 89.2% and 100 versus 80%, respectively, for the recurrence at the primary site. A total of 55 bony lesions at distant sites were detected on F-18 FCH PET-CT in comparison to 43 bone lesions on whole-body bone scintigraphy. F-18 FCH PET/CT also detected additional lung lesions in 2 patients and abdominal lymph nodes in 12 patients. F-18 FCH PET-CT could detect primary lesions, local metastasis, bone metastasis, and distant metastasis in a single study and is also a useful modality in recurrence evaluation in PCa patients.

Diagnostic Challenges in Right Iliac Fossa Mass Caused by a Fish Bone
Authors: Yahaya Ahmad Ibrahim , Burud Ismail , Zakariaa Jasiah
Published: February 2021

Right iliac fossa (RIF) mass is a common condition seen by surgeons. Despite advances in diagnostic modalities, it remains a diagnostic and therapeutic challenge, hence many authors describe RIF mass as temple of surprises. We report a challenging case of a 35-year-old man whopresented with a tender RIF mass. Abdominal ultrasonography (USG) and computed tomography (CT) scan abdomen were done and he was treated nonsurgically. His symptoms recurred after one month and a CT scan abdomen was repeated which revealed a suspicious foreign body within the appendicular mass. Laparotomy was performed which showed a macerated appendix with a 4-cm long fish bone within. The role of diagnostic tools in managing RIF mass and the treatment modality of appendicular mass are discussed. In managing RIF mass, a surgeon must be aware of thevarious differential diagnoses, but common diagnosis should always be entertained. Multi-modal diagnostic tools must be considered, including serial imaging in different planes.

Published: February 2021

Background: Ki67 levels have been shown to have good predictive value in breast cancer treatment. There is paucity of data on Ki67 levels in predicting response to neoadjuvant chemotherapy (NACT) in Kenya. This study evaluated the utility of Ki67 in predicting response to NACT.

Methods: This was a prospective observational study carried out at Kenyatta National Hospital between December 2017 and January 2019 onpatients with locally advanced breast cancer. We recruited 61 women through consecutive sampling technique. Data collected included patient demographics, pre-treatment tumor size, Ki67 levels and tumor biology. After 3 cycles of first-line chemotherapy, ultrasonography was used to determine response. Data were analyzed by SPSS for proportion of change in tumor size. The response was correlated with tumor biology and pretreatment levels of Ki67 using chisquare at a 95% confidence interval. A p-value <0.05 was considered statistically significant.

Results: The response rate after 3 cycles of NACT was 39.4%, sensitivity and specificity of Ki67 levels were 70.8% and 43.2% respectively with a cut-off value of 32.5%.

Conclusions: Ki67 was found to predict response in our context at a rate of 39.4% at 20% cutoff after 3 cycles.

Orofacial Infections in Kenya: A Retrospective Study
Authors: Mutwiri Kimathi Denis , Dimba Elizabeth , Nzioka Bernard Mua
Published: February 2021

Background: Orofacial infections are either odontogenic or non-odontogenic in nature. The clinical spectrum of these infections is diverse. This study aimed to describe the presentation and management of patients presenting with orofacial infections at Kenyatta National Hospital (KNH).

Materials and Methods: This was a retrospective study based on clinical records of patients treated for orofacial bacterial infections at KNH fromJanuary 2016 to December 2018. Data on the following study variables were obtained and analyzed: demographic data, clinical presentation,  diagnosis, management, and treatment outcome.

Results: 214 clinical records were studied. Male to female ratio was 1.4:1 with age range of 3 months to 78 years (mean=27.0 years). Swelling (96.30%, n=206) was the most common symptom, next was pain (58.90%, n=123). The most common source of infection was odontogenic (60.30%,n=129) in nature. Permanent teeth (57.00%, n=122) were more commonly involved than deciduous teeth (2.80%, n=6). In both dentitions, the mandibular posterior teeth were the most commonly involved, Ludwig’s angina (30.84%, n=66) and submandibular abscess (25.23%, n=54) were the most common clinical diagnoses of orofacial bacterial infection. The commonly used treatment modality was a triad of extraction of the associated tooth, incision and drainage, and antibiotic therapy. These management modalities resulted in favorable treatment outcomes (92.50%, n=198) in most cases.

Conclusion: Orofacial infections can occur among all sociodemographic groups. These infections are potentially life-threatening if not diagnosed early and managed promptly. Multidisciplinary teams are required to manage the severe morbidity and mortality of advanced orofacial infections.

This study was formulated to investigate productivity systems within Kenyan territorial waters. The interaction of processes on the margins of the marine waters, particularly the influx of fresh water loaded with sediments and nutrients, influences productivity of coastal waters. These deposited sediments, rich in nutrients, create a topographic barrier to the northerly flowing East African Coastal Current (EACC). Phosphate and nitrate peaks observed around the North Kenya Bank area provide evidence of an upwelling event. The contribution of sediments from the Lamu archipelago mangrove system is evident from the high observed particulate organic carbon (POC) input around the area. The system around the Lamu archipelago did not however show high chlorophyll-a levels despite the high POC influx. This may be due to the low levels of limiting phosphate in the surrounding waters, contrary to the observation further north in the region where high chlorophyll-a levels and corresponding higher phosphate levels were apparent. Productivity was largely supported by upwelling and organic matter mineralization. High levels of chlorophyll corresponded to high pelagic fish densities in the south (around 4.5°S) and north of the study area (around 2.5°S).
