The study adopted qualitative research approach using case study design. Three specific objectives and three research questions were used to guide the study. The population consisted of senior administrators from all the state tertiary institutions in the three geo-political zones in Bauchi State. The study had sample of respondents drawn from the population using purposive sampling technique. The numbers that constituted the sample size were five and drawn from College of Education Azare, College for Legal and Islamic Studies Misau and College of Education Kangere within the three educational zones of Bauchi state. Area of the study is Bauchi state. Semi-structured interview, observation and document analysis were used for data collection. Data collected were analyzed using content and thematic analyses to answer the research questions of this study. The results of the study were discussed in details from interviews and triangulated with the findings made from observations and documents. Based on the findings, it was concluded that politics affects curriculum development positively. It was recommended among others that politics of curriculum development should be done bearing in mind rationale economic calculus for educational development of tertiary institutions. Politics of curriculum development should be intended to improved sustainable tertiary institutions development and not the other way round. In spite of these, the politics of curriculum development has made it difficult to properly plans and administer educational policies and management which has affected the enrolments, federal character policies, control of education among others.

Authors: Oladokun A. Tajudeen , Aderibigbe N.B.
Published: May 2022

Noise is an important environmental problem in major cities of tropical African countries with Nigeria not exempted. The study adopted a quantitative measurement of noise at selected sites having heterogeneous spatial characteristics. The data collected were analyzed using totals, means, t-test and a two-way ANOVA. The study showed that noise is a feedback mechanism stemming from myriads of urbanization and industrialization processes, poor urban planning, social functions, vehicular activities (hooting), household activities, hawking and other commercial activities of the recent times. The study also showed that noise level is functionally related to temporal and spatial characteristics of places. All these have resulted in vulnerability and exposure of the cities dwellers to noise related health impairment despite the presence of some health care centres. The immediate responses known to have followed excessive noise in these areas are hearing loss, sleeping disorder, annoyance, communication impairment, health related problems like cardiovascular diseases, temporary or permanent deafness and the likes. It is hereby recommended that adequate and timely environmental education be organized for people to have a change of attitude towards noise level reduction in particular and environmental pollution in general.

Defending Innovative Theologies
Authors: Tucker Rev Gabrielle H , Nortjé-Meyer Prof Lilly (SJ)
Published: May 2022

Colonialism never was intended to be a short-term project, and it laid a foundation that projected itself 200 years into the future – stifling the voices, ideas, dreams and ambitions of all it touched. The church, particularly in ‘post colonies’ in the Global South, wrestles with coloniality, where such impositions influence racial, gender and class divisions, where female church groups, lay and clergy women, still struggle in reclaiming their identity, and issues of patriarchy and endemic poverty. This struggle for transformation is unfortunately waged in silence, with ways to “break down walls that divide us”. It is in this context of struggle that innovative Christian theologies can
be elevated by women with the intention of transforming all of society.

In order to develop a suitable theological interpretation of innovative theologies, that is capable of neutralising the insidious impacts of coloniality and its historical embedded impediments, requires that our journey of re-discovery explore very intensely our African indigenous heritage in order to find answers that free the soul from systemic oppression. New methods of using unexplored epistemologies should be investigated for their contributory value. Creating an ontology, new innovative theologies that can transform existing beliefs in order to advance, transform and contribute in a manner in which readers and hearers interpret the Bible, enhancing the embracement of their African identity requires a collective input.

Published: May 2022

Introduction. Due to the COVID-19 pandemic, teaching conditions changed around the world from in-person classes to online classes, which also determined changes on teachers’ working conditions.
Method: Exploratory cross-sectional study with the aim of determining the association between two voice symptoms (vocal fatigue and throat pain) with home working conditions during online classes in times of COVID-19 pandemic. Professors answered an online survey including 27 questions about four components: sociodemographic factors, characteristics of home working, quarantine characteristics, and health conditions (including voice functioning).
Results: 177 college professors from Argentina, Colombia, and Chile participated in this study. First, incidence of vocal fatigue, during online classes in times of COVID-19 pandemic, represented around 50%. Although throat pain had a smaller incidence, it was also important (35%). Second, days in quarantine, number of classes per week, people living with during quarantine, and history of vocal fatigue before quarantine were important associated factors of vocal fatigue. Third, important associated factors of throat pain were number of classes per week, level of stress, years of experience, and history of throat pain before quarantine.
Conclusion: Similar to pre-COVID-19, vocal fatigue and throat pain were frequently reported voice symptoms among college professors. Associated factors of these symptoms included years of experience, number of classes per week, stress, people living with during quarantine due to COVID-19, and history of voice symptoms. Workplace Health Promotion programs should include activities that facilitate a healthy occupational voice use during and post-COVID-19 pandemic, considering the implications of online teaching on teachers’ health and safety.

Neste trabalho procuro discutir as potencialidades da linguagem da Arte na educação geográfica a partir de uma experimentação com algumas obras do acervo permanente do MARCO (Museu de Arte Contemporânea de Mato Grosso do Sul) realizada com estudantes do Ensino Fundamental da Rede Pública Estadual do município de Fátima do Sul (MS). Além de estimular a participação ativa dos estudantes, dialogando sobre suas percepções e criando suas próprias obras, a experimentação também proporcionou o contato dos estudantes com uma parte da produção artística sul-mato-grossense. Utilizo as obras não apenas para ilustrar o conteúdo, mas para potencializar imaginações sobre o espaço. Baseio a discussão em conceitos propostos por autores como Doreen Massey (2008), Gilles Deleuze (2013), Felix Guattari e Suely Rolnik (2013), entre outros, referenciando a aproximação da Arte com a Geografia.

Art and geographical education: possibilities from artworks of the Contemporary Art Museum in Mato Grosso do Sul (MARCO)
Abstract
This paper look up to discuss the potentialities of the language of Art in geographic education from an experiment with some artworks from the permanent collection of Museum of Contemporary Art of Mato Grosso do Sul (MARCO) carried out with Elementary School students from the State Public Network of the city of Fátima do Sul (Mato Grosso do Sul State). Besides encouraging the active participation of students, talking about their perceptions, and creating their own works, the experimentation provided students with contact with part of the artistic production in the state of Mato Grosso do Sul. We use the artworks not only to illustrate the content, but also to enhance imaginations about space. We based the discussion on concepts proposed by authors such as Doreen Massey (2008), Gilles Deleuze (2013), Felix Guattari and Suely Rolnik (2013), among others, referencing our understanding of the approximation between Art and Geography.

Published: May 2022

This research work is focused on the enzymatic hydrolysis of amaranth (Amaranthus hypochondriacus) stubble to obtain peptides and demonstrate their antioxidant activity. To this aime, we analyzed extracts of leaves and stems of this plant species. Amaranth stubble was dried and grounded to 0.1 mm particle size and treated by enzymatic digestion using Flavourzyme® or Alcalase®. The hydrolysis degree was 16.31 % and 12.64 %, for each digestion, respectively. The peptides obtained showed antioxidant activity in all the range of molecular size from < 1 kDa to >10 kDa. Our findings indicate that amaranth stubble is an available material that can be used to obtain peptides with antioxidant activity.

Authors:   Professor, Tashkent Medical Academy, G.I. Shaykhova
Published: May 2022

The article is devoted to the role of iron, vitamins and minerals in the development of iron deficiency anaemia in children of early and pre-school age. Iron deficiency (ID) is one of the most common nutritional-dependent states in the world, which, according to WHO [1], affects more than 1.5 billion people. Iron deficiency is in the form of iron deficiency anaemia (IDA) [1, 2] in about half of the cases (over 700 million of the world’s population). ID is mostly due to nutritional reasons, but age and socio-economic factors are also important.

Authors:   Independent researcher, Andijan State Medical Institute, S.Sh. Egamov
Published: May 2022

For the period from 2001 to 2020, 1567 patients were operated on for duodenal ulcers (DU) on the basis of the Department of Surgical Diseases and Urology of the Andijan State Medical Institute. At the same time, “difficult” DU was diagnosed in 494 (31.5%) patients. Of these, 364 (73.7%) patients were operated on in a planned manner and 130 (26.3%) – in an emergency. The subject of our study were only 262 patients with “difficult” DU who were admitted to the clinic in a planned manner. At the same time, the control group consisted of 114 (43.5%) patients and the main group – 148 (56.5%) patients. Thus, the analysis of the causes of undesirable consequences and the revision of surgical tactics, taking into account the omissions made in patients of the control group and the widespread use of improved methods and techniques of operations, made it possible to reduce the frequency of postoperative complications associated with surgical intervention on the stomach – by 12.6% (from 19 .3 to 6.7%), as well as mortality by 5.4% (from 6.1 to 0.7%). All this allowed us to achieve the desired goal.

Synovial chondromatosis is a generally monoarticular disorder characterized by multiple benign nodular cartilaginous formations, arising as a result of metaplasia of synovial tissue. Other names by which this entity is known are synovial osteochondromatosis, primary synovial chondromatosis, synovial chondrometaplasia. The most frequent location is the knee, hip, shoulder, shoulder, elbow, wrist and temporomandibular joint. It can be primary or secondary to a pre-existing chondromatosis. 1-8 It is an uncommon entity with a worldwide incidence of 1:100,000 with greater involvement of males up to 3 times higher. It usually affects people between 30 and 50 years of age, and although its etiology is unknown, it has been associated with chromosomal effects. In studies published between 1996 and 2002, structural alterations were found, which showed a rearrangement of bands 1p13-p22. 1, 2, 3, 9, 10, 11
Contribuições da anatomia à taxonomia de Tetrapterys Cav. (Malpighiaceae) e gêneros segregados
Authors:   , Matos Rafael Ribeiro de
Published: May 2022

Malpighiaceae A. Juss é uma família monofilética que compreende cerca de 77 gêneros e 1300 espécies. Entretanto, a semelhança na morfologia floral, dos frutos e do pólen, além de mesmo número de cromossomos tem dificultado os arranjos taxonômicos e o entendimento das relações de parentesco em níveis inferiores como subfamílias, tribos e gêneros. Alguns táxons também emergiram como grupos polifiléticos em hipóteses filogenéticas baseadas em dados moleculares e morfológicos. Tetrapterys e Mascagnia sofreram mudanças drásticas em sua circunscrição taxonômica, com a proposição de desmembramento de novos gêneros e elevação de seções à gênero. Assim, o presente estudo objetivou encontrar caracteres anatômicos foliares e micromorfológicos que possam contribuir para a resolução dos problemas taxonômicos no clado Tetrapteroide, em especial quanto ao tratamento taxonômico proposto por Almeida e Van den Berg (2021), no qual Aenigmatanthera é sinonimizado a Niedenzuella e Tetrapterys é redefinido com a exclusão de parte das espécies que foram alocadas no novo gênero Glicophyllum. O presente estudo realizou pela primeira vez a descrição anatômica e micromorfológica de Tetrapterys, bem como dos seus gêneros segregados e/ou proximamente relacionados, apontando novos caracteres diagnósticos capazes de identificar os três gêneros estudados. Corroborando com a circunscrição genérica proposta por Almeida e Van den Berg (2021). Através da utilização de caracteres anatômicos é possível identificar 33 das 35 espécies utilizadas na chave de identificação, englobando cerca de metade das espécies totais de Niedenzuella e ⅔ das espécies de Glicophyllum e Tetrapterys ocorrentes no Brasil, além de seis espécies de Tetrapterys não nativas do país. Propomos ainda, baseados em nossos dados, a realocação ou reposicionamento de G. fimbripetalum no gênero Tetrapterys. Apontamos valor taxonômico no uso de novos caracteres anatômicos, bem como uma metodologia padrão e clara para a análise de margem. Contudo, reforçamos a importância do uso da anatomia para a interpretação de relações filogenéticas entre grupos, sobretudo aliados a dados morfológicos e moleculares.Palavras-chave: Malpighiaceae neotropicais.

Avaliação da densidade superficial do mar e conteúdo de calor oceânico no Oceano Austral a partir de dados de reanálises
Authors:   , Reis Rafael Afonso do Nascimento
Published: May 2022

O Oceano Austral é uma peça-chave do clima global. Ele sozinho é responsável pela maior parte do sequestro de dióxido de carbono e calor antropogênico. Apesar de sua importância, ele permanece pobremente amostrado e muitos estudos visam a utilização de reanalises e modelos oceânicos para melhor compreender este tão importante oceano. Com base nisso, este trabalho estuda a capacidade das reanálises GLORYS, ORAS5 e GODAS em representarem a densidade neutra em superfície e o conteúdo de calor na camada de 0 a 300 metros do Oceano Austral. As reanálises apresentam erro na densidade neutra em relação aos dados coletados in situ, variando entre -1 e 2 kg/m³. A maior parte dos erros significativos ocorre na década de 1990 em virtude da baixa cobertura de dados de sensoriamento remoto da região. As tendências de densidade neutra das reanálises são distintas, devido aos diferentes perfis de salinidade. Todas as reanálises apresentam perfis de tendência de temperatura e de fluxos de densidade muito similares. O ORAS5 é o mais diferente entre as reanálises, pois apresenta uma tendência negativa de salinidade e de densidade neutra para a maioria do Oceano Austral. Acredita-se que o motivo dessa tendência é o fato de sua salinidade ser restringida por um processo chamado nudging. Em relação ao conteúdo de calor, todas as reanálises apresentam crescimento do conteúdo de calor, sendo o mais intenso o GLORYS com um aumento de 1,38x10 18 J/yr. O primeiro módulo de variabilidade das reanálises é diretamente ligado ao ENOS com GLORYS e ORAS5 apresentando uma correlação maior que GODAS e tendo um claro Dipolo Antártico. O segundo modo de variabilidade é representado por GLORYS e ORAS5, por estar relacionado aos vórtices oceânicos, cuja reanálise GODAS não resolve. GLORYS e ORAS5 são as únicas a apresentarem correlação com a MAS. A MAS impacta o conteúdo de calor também com um Dipolo Antártico, mas de maneira contrária ao ENOS. Ao se retirar o sinal do ENOS da correlação da MAS com o conteúdo de calor, é possível verificar que ela perde a característica de dipolo. Isso indica que a MAS age mais como um regular do impacto do ENOS do que por si própria no Oceano Austral. Os dois modelos oceânicos MOM025 e MOM, rodados com os parâmetros do experimento CORE-II, falham em representar o conteúdo de calor no Oceano Austral; bem como seus módulos de variabilidade em razão de eles descartarem o impacto do ENOS no conteúdo de calor.

Aim: Prolonged operative timing is likely to negatively impact clinical outcomes and accurate preoperative prediction of those likely to undergo longer procedures can assist theatre planning and postoperative care. We aimed to apply artificial neural networks (ANN) as a predictive tool for prolonged operating time in laparoscopic colorectal surgery. Methods: A dedicated, prospectively populated database of elective laparoscopic colorectal cancer surgery with curative intent was utilised. Primary endpoint was the prediction of operative time. Variables included in the network were: age, gender, ASA, BMI, stage, location of cancer, and neoadjuvant therapy. A multi-layered perceptron ANN (MLPNN) model was trained and tested alongside unit and multivariate analyses. Results: Data from 554 patients were included. 400 (72.2%) were used for ANN training and 154 (27.8%) to test predictive accuracy. 59.3% male, mean age 70 years, and BMI of 26. 161 (29%) were ASA III. 261 (47%) had rectal cancer and 8.5% underwent neoadjuvant treatment. Mean operative time was 218 minutes (95% CI 210-226) with 436 (78.7%) of less than 5 hours and 16% conversion rate. ANN accurately identified and predicted operative timing overall 87%, and those having surgery less than 5 hours with an accuracy of 93.3%; AUC 0.843 and 93.3%. The ANN findings were accurately cross-validated with a logistic regression model. Conclusion: Artificial neural network using patient demographic and tumour data successfully predicted the timing of surgery and the likelihood of prolonged laparoscopic procedures. This finding could assist the personalisation of peri-operative care to enhance the efficiency of theatre utilisation.

Introduction: Gastrointestinal disorders (GI) including hepatobiliary-pancreatic (HBP) diseases are a cause for significant morbidity and mortality. Mortality due to nonmalignant disorders are often diagnosed but are less studied. Limited autopsy-based studies have been conducted on gastrointestinal causes of death despite gastrointestinal and hepato-biliary-pancreatic diseases being one of the important causes for morbidity and mortality. Autopsy is still considered a valuable tool in reliably determining the underlying pathology and cause of death. This study of gastrointestinal causes of death was conducted to evaluate and understand its impact. Methods: This is a 5-year retrospective autopsy-based study for the period August 2016 to July 2021. Data was collected from autopsy request forms, patients’ hospital records and autopsy reports, which included age, gender, ethnicity, salient clinical features, key autopsy findings and the cause of death. Results: During the 5-year period, a total of 3435 autopsies were performed, out of which 294 cases were found to have gastrointestinal-hepato-biliarypancreatic (GIHBP) disorders as the cause of death, contributing to 8.6%. This accounts for the third leading cause of death. The main causes of death were gastrointestinal bleeding (GIB) (26%), perforation of a viscus organ and peritonitis (23%), hepato-biliary-pancreatic disease (17%), ischemic bowel changes (13.6%), neoplastic disease (11.6%) and others. Majority of patients were males and of African ethnicity. Patients aged above 40 years accounted for 83% of the deaths. Abdominal pain was the most common presenting symptom. Three leading autopsy findings include gastrointestinal bleeding, ascites, perforation and peritonitis. Conclusion: GIHBP disorders are the third leading cause of death. GI bleeding, non-traumatic perforation and peritonitis are identified as significant mechanisms of death. Autopsy still plays an important role in reliably determining the cause of death. Prompt diagnosis and appropriate management may decrease mortality. This study augments the limited body of literature and provides insight into gastrointestinal causes of death.

Published: May 2022

Education means of delivery has been transformed from in person to online learning because of COVID-19. This study assesses factors influencing the use of Google Classroom (GC) in four northern states located in Peninsula Malaysia for lessons during the COVID-19 pandemic among secondary ESL educators. A non-experimental design was employed. Primary data collected from a self-administered online questionnaire were analysed descriptively in a general survey of trends, involving 103 survey respondents (i.e., teachers). The findings of this study will allow Malaysian education stakeholders to understand the factors influencing the use of GC in schools to enable appropriate decisions about its use among teachers. It will also assist Malaysia's Ministry of Education in formulating policies relating to the use of GC and assist administrators of secondary schools in making decisions on the type of infrastructure and technical support needed. To evaluate the factors affecting GC used for instructions, a longitudinal study is recommended as such study will indicate whether longer periods of instructions result in better use of GC or not. This study extends significance in the field of instruction for teachers since it can be used to perform additional studies to increase the use of GC by teachers. To better evaluate the power of GC’s instructions or other learning management systems in advancing virtual instruction prowess, a potential global expansion of this study should be performed.

Authors: Gasanova A. S. , Izmailov A. Ch.
Published: May 2022

The method of sub-Doppler fluorescence spectroscopy is proposed, which is based on the features of the narrowing with time of the velocity distribution of optically excited atoms (molecules) of a rarefied gas medium in a thin cell after exposure to a sufficiently short light pulse. Changes in the established sub-Doppler resonances with time as well as the essential dependence of these resonances on dimensions of the gas cell are analyzed.

Published: May 2022

The comparative study of the spectral-luminescent properties of hydrophilic 21-thia-5,10,15,20-tetra-(4-sulfonatophenyl)-porphyrin and 5,10,15,20-tetra-(4-sulfonatophenyl)-porphyrin is carried out in solutions at 293 K. The peculiarities of the halochromic effects have been revealed for the first time, which were due to the replacement of the pyrrole ring by thiophene in the macrocycle. It is found that multicenter interactions

on the periphery and in the core of the macrocycle led to the modulation of the spin-orbit interactions which became apparent in changes of the fluorescence quenching efficiency. It is shown that the fluorescence of the doubly protonated form of heteroporphyrin deceases compared to the free base whereas the

double protonated form of porphyrin reveals the fluorescence enhancement.

Authors: Rotshteyn V. M. , Turdaliev T. K. , Ashurov Kh. B.
Published: May 2022

The technologies of obtaining nanostructured silicon, including porous nanosilicon are presented. The method for the synthesis of porous nanosilicon using electrochemical etching is described. The main parameters of the generation of porous silicon with specified characteristics are given. The results of the study of nanostructured porous silicon samples using a Renishaw InVia Raman Spectrometer are described in detail. This spectrometer permits to register and identify both amorphous and crystalline phase components in the samples. According to the results of granulometric studies, the crystal structure of the samples is established. The approximation of the Raman spectra confirms the absence of amorphous silicon in the samples under study. In the Raman spectra of the samples, a shift of lines towards lower energies is observed, which is characteristic of nanoparticles with a decrease in their size. The photoluminescence spectra of the synthesized samples of porous silicon exhibit a stable intense band in the range 700—900 nm, which confirms the nanocrystalline nature of the samples. We demonstrate the efficiency and sensitivity of Raman spectroscopy, which makes it possible to register even insignificant changes in the crystalline and amorphous fractions of silicon structures.

Помидор етиштириш жараёнида биостимуляторларнинг таъсир этиш самарадорлигини ўрганиш мақсадида уруғларни экишдан аввал ўрганилаётган намуналар ивитилганида назоратга нисбатан помидорниниг униб чиқиши 6,7 – 11,1% га ошди. “Агростимул”, “Бион” ва “Новосил”  препаратларини қўллаш ўсимликларнинг ўсиши ва ривожланишига ижобий таъсир кўрсатди. Меваларнинг етилиш фазасида биометрик кўрсаткичлари назорат ва тажрибада ўсиши ўсимликларнинг баландлиги бўйича 11,9 – 44% (энг кўп фоиз – “Новосил”да), ўсимликларнинг массаси 28,4 – 52,7% (энг кўп фоиз – “Агростимул”да), барглар сони бўйича 18,2 – 28,2% (энг кўп фоиз – “Бион”да), ён куртлари бўйича 59,4 – 86,4% (энг кўп фоиз – “Бион”, “Агростимул”, “Новосиль”) ва мевалар сони билан 25- 40% (энг кўп фоиз –“Бион”да). Биостимуляторлар ҳар хил даражада қўллаш помидорда учрайдиган асосий касаллик – альтернариознинг ривожланишига таьсир кўрсатда. Препаратни кўллашнинг 1-ҳисоботида биологик самарадорлик 29,8 – 61,6% га тенг бўлди, ҳҳосилни йиғиштиришда бу кўрсаткичлар 6,2 – 10,7% га пасайди. Биостимулятор “Бион” уруғларни экишдан аввал ивитилганди ва икки марта помидор ўсимликларига пуркалганди, касалликни ривожланиши самарали тўхтатди. Препаратлар помидорлар мевасининг оғирлигини сезиларли даражада орттиришига ўртача “Агростимул” да 8,1 га – “Бион” да 16,1 г назоратга нисбатан (77,3 г) кўрилди. Энг кўп ҳҳосилдорлик 32,9% “Бион” стимулятори кўлланган вариантда эришилди.
Препаратларни қўллаш ҳосилдорликнинг сифатига ижобий таъсир кўрсатди – касал мевалар миқдори 1,5 – 2,4 марта камайди.
