Antibiotics are one of the most exploited metabolites produced by soil actinomycetes. This study isolated fifteen actinomycetes (A1 â€“ A15) from dumpsite soils within Ilorin metropolis & screened them for antibacterial activity. Isolates were identified with morphology & biochemical characteristics.Their activity against clinical bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae & Staphylococcus aureus) was determined. Their bioactive metabolites after fermentation was assayed for by agar well diffusion & compared with reference antibiotics. Molecular analysis of two most active isolates was done. The most active metabolite was subjected to GCMS. All isolates were identified as Streptomyces, 7 isolates exhibited activity against 3 test bacteria with highest (10.5mmÂ±0.35) by Streptomyces griseoplanus while S. aureus demonstrated total resistance to all isolates. Secondary activity revealed 7 of the metabolites as effective against the bacteria with highest activity (28.5Â±1.04mm) by S. sparsogenes showing similar activity with Cefuroxime (28.01Â±0.01mm). The two most active isolates were Streptomyces griseoplanus strain NR725RL-ISP 5009 & Streptomyces sparsogenes strain NBRC 1308616S & RNA nucleotide similarity revealed close phylogenic relationship. GC-MS revealed10 compounds in S. sparsogenes strain NBRC 1308616S metabolite. Streptomyces from dumpsite soils within Ilorin produced bioactive compounds against clinical test bacteria and thus could be potential sources of antibiotics.
AN EFFICIENT HYBRID DERIVATIVE-FREE PROJECTION ALGORITHM FOR CONSTRAINT NONLINEAR EQUATIONS
Authors: Muangchoo Kanikar
Published: November 2021

In this paper, by combining the Solodov and Svaiter projection technique with the conjugate gradient method for unconstrained optimization proposed by Mohamed et al. (2020), we develop a derivative-free conjugate gradient method to solve nonlinear equations with convex constraints. The proposed method involves a spectral parameter which satisfies the sufficient descent condition. The global convergence is proved under the assumption that the underlying mapping is Lipschitz continuous and satisfies a weaker monotonicity condition. Numerical experiment shows that the proposed method is efficient.

Authors: Dissanayake Dilini , Dissanayake Sulochana , Ajward Roshan
Published: November 2021

Disclosure of sustainability practices has become vital for organizations to secure their image as legitimate corporate citizens in society (Panjaitan, 2017). It might be influenced by the board of directors subject to the performance and resource availability. The prime objective of the paper is to investigate the association between board characteristics and a level of sustainability disclosure with the moderating role of performance gap and resources. Secondary data was obtained from 174 non-finance firms representing 16 sectors of the Colombo Stock Exchange (CSE) over 2016–2020. The study used 13 board characteristics and 7 controlling variables. According to the results of ordered logistic regression, board size and audit committee size have a significant impact on the degree of sustainability disclosures. At the same time, female directors displayed a significant adverse effect on such disclosures. It was found that resource availability significantly impacts the relationship between board characteristics and sustainability reporting. The study contributes to the extant literature by filling an empirical gap in the area by encapsulating a more comprehensive sample, using a broader theoretical perspective and a wide measurement to capture sustainability disclosure. The study findings are predicted to have extensive managerial ramifications in strengthening corporate governance mechanisms to elevate sustainability disclosure

Published: November 2021

MicroRNAs (miRNAs) are part of deregulated insulin secretion in type 2 diabetes (T2D) development. Rodent models have suggested miR-200c to be involved, but the role and potential as therapeutic target of this miRNA in human islets are not clear. Here we report increased expression of miR-200c in islets from T2D as compared with nondiabetic (ND) donors and display results showing reduced glucose-stimulated insulin secretion in EndoC-βH1 cells overexpressing miR-200c. We identify transcription factor ETV5 as the top rank target of miR-200c in human islets using TargetScan in combination with Pearson correlation analysis of miR-200c and mRNA expression data from the same human donors. Among other targets were JAZF1, as earlier shown in miR-200 knockout mice. Accordingly, linear model analysis of ETV5 and JAZF1 gene expression showed reduced expression of both genes in islets from human T2D donors. Western blot analysis confirmed the reduced expression of ETV5 on the protein level in EndoC-βH1 cells overexpressing miR-200c, and luciferase assay validated ETV5 as a direct target of miR-200c. Finally, LNA knockdown of miR-200c increased glucose-stimulated insulin secretion in islets from T2D donors approximately threefold. Our data reveal a vital role of the miR-200c–ETV5 axis in β-cell dysfunction and pathophysiology of T2D.
Exercise-Induced Improvement in Insulin-Stimulated Glucose Uptake by Rat Skeletal Muscle Is Absent in Male AS160-Knockout Rats, Partially Restored by Muscle Expression of Phosphomutated AS160, and Fully Restored by Muscle Expression of Wild-Type AS160

Published: November 2021

One exercise session can elevate insulin-stimulated glucose uptake (ISGU) in skeletal muscle, but the mechanisms remain elusive. Circumstantial evidence suggests a role for Akt substrate of 160 kDa (AS160 or TBC1D4). We used genetic approaches to rigorously test this idea. The initial experiment evaluated the role of AS160 in postexercise increase in ISGU using muscles from male wild-type (WT) and AS160-knockout (KO) rats. The next experiment used AS160-KO rats with an adeno-associated virus (AAV) approach to determine if rescuing muscle AS160 deficiency could restore the ability of exercise to improve ISGU. The third experiment tested if eliminating the muscle GLUT4 deficit in AS160-KO rats via AAV-delivered GLUT4 would enable postexercise enhancement of ISGU. The final experiment used AS160-KO rats and AAV delivery of AS160 mutated to prevent phosphorylation of Ser588, Thr642, and Ser704 to evaluate their role in postexercise ISGU. We discovered the following: 1) AS160 expression was essential for postexercise increase in ISGU; 2) rescuing muscle AS160 expression of AS160-KO rats restored postexercise enhancement of ISGU; 3) restoring GLUT4 expression in AS160-KO muscle did not rescue the postexercise increase in ISGU; and 4) although AS160 phosphorylation on three key sites was not required for postexercise elevation in ISGU, it was essential for the full exercise effect.

Adipose
derived stem cells (ADSCs) can differentiate into vascular lineages and
participate in vascular remodeling. Perivascular ADSCs (PV-ADSCs) draw
attention due to their unique location. The heterogeneity of subcutaneous (SUB-)
and abdominal ADSCs were well addressed, but PV-ADSCs’ heterogeneity hasn’t
been investigated. In the present study, we applied single-cell analysis to
compare SUB-ADSCs and PV-ADSCs respectively regarding their subpopulations, functions,
and cell fates. We uncovered 4 subpopulations of PV-ADSCs including Dpp4+,
Col4a2+/Icam1+, Clec11a+/Cpe+ and Sult1e1+
cells, among which Clec11a+ subpopulation potentially
participated in and regulated the PV-ADSCs differentiation towards a smooth
muscle cell (SMC) phenotype. The present study revealed the distinct characteristics between
PV-ADSCs and SUB-ADSCs.
Multispot optics for beam shaping of high-power single-mode and multimode lasers

Published: November 2021

The performance of various laser technologies, such as welding, laser powder bed fusion (LPBF), brazing, cladding, and sheet metal cutting, based on the use of high-power multimode fiber lasers, fiber-coupled solid-state, and diode lasers, can be improved using the patent pending beam-shaping optics providing optimal energy distributions by splitting the laser beam into several separate spots in the working plane and variable energy sharing between these spots. Various patterns, such as square, line, and rhombus, consisting of four or nine separate spots, are expected to eliminate or reduce spatter and to realize optimum temperature distributions in the melt pool and stabilizing the processes in the welding of tailored blanks, copper and aluminum parts in the production of batteries, zinc-coated steel, cladding, and LPBF. Because multimode lasers have a comparably low spatial coherence characterized by large beam parameter products or beam quality (M²) values, it is difficult to control the intensity distribution by methods other than imaging the fiber end with a collimator and a focusing objective. The proposed solution is a combination of fiber end imaging and geometrical separation of focused spots perpendicular to the optical axis using special optical components and creating a working spot as a combination of several spots. Varying the energy portions in separate spots and the distances between them make it possible to optimize common spot intensity distributions for particular applications. To ensure reliable operation with multi-kW lasers, the refractive optical components of the multispot devices are implemented from athermal optical materials characterized by insignificant thermal lensing and, hence, negligible thermal focus shift and spherical aberration. The article presents descriptions of multispot optics and examples of intensity profile measurements and application results, while the reduction in spattering was observed using multispot laser welding. It is concluded that the melt pool flows homogenize when applying several laser spots compared to a single spot. The possibility of tailoring melt pool dimensions in LPBF was shown.

Published: November 2021

During the laser-powder bed fusion process on aluminum alloys, instabilities such as spatter ejections result from the laser-matter interaction. These spatters create a variety of defects and affect the mechanical properties of the final parts. To help in understanding this phenomenon, a global method was developed, combining experimental study and image analysis. This system provides statistic information on spatter population (radius, velocity, direction, and emission rate), and the idea of pollutant spatter is defined. Four aluminum alloys are compared. The results show that the oxygen content in the fabrication chamber has no effect on the spatter ejection dynamic. The spatter velocity, angle of ejection, and size increase with intensity. Also, significant differences are noticed between the different alloys.

Published: November 2021

The acquisition of procedural and conceptual knowledge is imperative for the development of problem solving skills in mathematics. However, while there are mixed research findings on the relationship between the two domains of knowledge in some branches of mathematics, the relationship between learners’ procedural and conceptual knowledge of algebra has not been well explored. This research paper examined the relationship between Grade 11 learners’ procedural and conceptual knowledge of algebra. Data for the study was collected using an algebra test administered to 181 grade 11 learners in Gauteng province, South Africa. Descriptive statistics and Pearson’s correlation coefficient were used to analyse the data in SPSS. The study revealed that the learners have low levels of both procedural and conceptual knowledge of algebra. However, they displayed better procedural knowledge than the conceptual knowledge of algebra. In addition, a statistically significant moderate positive linear relationship was found between the learners’ procedural and conceptual knowledge of algebra.

Technology and Truth. Reflections on Russia, America, and Live Not By Lies
Authors: Grenier Paul
Published: November 2021

The main thesis of the author of the essay is that in contemporary Western society the objective and subjective truth is created by the people. This is the key to what the author calls technological and technocratic society for which truth and reason are no longer the goals that the man should be striving for in his thoughts and behavior. In a technocratic society the reality itself is created and thus accordingly the term “lie” loses its meaning. Anything can potentially be viewed as a useful step in the process of creating something new and “efficient” for those who above all value the strengthening of their own control (over people, nature, etc). Subjects acting in the framework of technological society deny any identifications and technologically determine themselves what man, nature and society is, – right down to the basics of our biological existence. This approach overturns such notion as absolute truth, establishing relevant truth. In contemporary Western society subjective and objective truth is created. The author examines in detail how this approach is used by the United States in their international policy to achieve dominance. He also considers Russia to be the only great power that is prepared to choose a different line of development due to its historical development. The possibility of such choice is capable to prevent final Americanization of Europe, which, should it happen, would lead to the “mankind as a whole losing its past”, as Simone Weil predicted.
Post-liberal Communitarianism in Contemporary Russia: Future in the Legacy of the Past
Authors: Bakurkov Anatoly A. , Tyapin Igor N.
Published: November 2021

The address to communitarianism as a system of ideas and a model of the “ideal type” of a public organization can serve as the foundation for scientific and philosophical research of the problems of organizing public dialogue and social consolidation, the implementation of the organic relationship of technological progress with institutional and anthropological conservatism. The issue of communitarianism has a certain tradition in Russian thought of different eras and directions (Slavophilism, philosophy of the “new religious consciousness”, Eurasianism, ethical and anthropological studies in Soviet – orthodox and non–Marxist – philosophy and certain recent historical, philosophical and political science works), which is both indirect and in some cases quite direct. Comparing the approaches of domestic and foreign authors to the factors of transformation of society on the principles of social harmony allows us to conclude that when in Western philosophy communitarianism is simply the criticism of liberalism and the search for a balance between various social forces interests, in Russia it is capable to reach a fundamentally higher axiological and theoretical level within the framework of integration with the conceptual baggage of the Russian idea and the real experience of the state of social justice understanding.

Donec non sumus deos temporis: id talis machina nobis non est!..
Authors: Ашшурский Эмир
Published: November 2021

Не секрет, что в нынешнюю поистине головокружительную эпоху перемен наука стала уже развиваться куда более впечатляющими темпами. Благодаря чему человечество довольно-таки успешно осваивает сейчас всё новые и новые неизведанные горизонты, тем самым приоткрывая для себя очередные сокровенные завесы бытия.

Что же касается потенциальных путешествий во времени, то задолго еще до начала серьезных академических исследований эта достаточно экстравагантная тема не раз затрагивалась в популярных произведениях целого ряда всемирно известных писателей-фантастов. Так, о полетах в будущее очень ярко и увлекательно поведал нам англичанин Герберт Уэллс в своем романе «Машина времени», а об аналогичных вояжах в прошлое – американец Рэй Брэдбери в рассказе «И грянул гром».

Со своей стороны, пытались не отставать от признанных зарубежных классиков и ведущие советские специалисты. Конкретно же речь здесь прежде всего идет о братьях Стругацких, В.А.Черноброве, С.В.Красникове, ну и, разумеется, И.Д.Новикове. И вот как раз критическому анализу отдельных весьма спорных взглядов и гипотез последнего из них (а если точнее – умозрительно выдвинутого им принципа самосогласованности) и посвящена большая часть данной авторской статьи. Причем особое внимание уделяется в ней доказательству абсолютного концептуального запрета на перемещения в прошлое. Ибо де-факто максимум, что можно было б тут еще на практике реализовать (да и то – не без изрядной доли скепсиса и трезвой иронии), так это тестовую отправку неких роботоподобных портативных систем, которые не будут якобы там замечены местными ретро-туземцами. Хотя, в общем-то, даже и это компромиссное рацпредложение отнюдь не претендует на оригинальность, поскольку перекликается, так или иначе, с основными тезисами современной уфологии.

В целом же автор напоследок подводит своего читателя к вполне аргументированному выводу, что распутывание наиболее сложных мировоззренческих проблем сущего лучше всё-таки, очевидно, доверять философам, а не технарям!

Hydraulic expansion facilitates remodeling of arteriovenous fistulas without increasing venous intimal hyperplasia in rabbits
Authors: Ren Wanjun , Niu Jiyuan , Du Yuejuan , Jiang Huili
Published: November 2021

Background

An arteriovenous fistula (AVF) is considered essential for chronic hemodialysis.

Objective

To determine the effects of hydraulic expansion on the intimal hyperplasia of an AVF.

Methods

We divided 12 healthy male New Zealand white rabbits into a control group (vein without special handling and direct anastomosis with an artery, n = 6) and a hydraulic expansion group (vein dilated by hydraulic pressure before anastomosis, n = 6). Histopathomorphology was examined with hematoxylin and eosin staining and immunohistochemistry. Analysis of covariance (ANCOVA) was used to compare the data between the groups.

Results

Immediately and 1 day after surgery, the diameter of the fistula vein in rabbits in the hydraulic expansion group was significantly larger than it was in the control group (P = 0.02 and 0.03 respectively), but not on subsequent days. After hydraulic expansion and before construction of the fistula, the wall of vein was noticeably thinner on macroscopic observation, and the anterior and posterior walls were indistinguishable. At 3 weeks after surgery in the hydraulic expansion group, cells in the vein wall were disordered, there were fewer elastic fibers, tissues from the endothelium to tunica externa were less dense, and there was less extracellular matrix than in the control group. Expression of connective tissue growth factor in the hydraulic expansion group was significantly less than that in the control group (P = 0.01). No differences were found in intimal thickness or immunohistochemistry scores for transforming growth factor-β1 between the groups.

Conclusion

Hydraulic expansion did not increase intimal hyperplasia of an AVF, but facilitates remodeling of AVFs in rabbits.
Cash Flow and Profit Impact on Capital Account Liberalization-Investment Growth Nexus in Nigeria: An Aggregated Firm Case
Authors: Okungbowa Ewere Florence O.
Published: November 2021

The article examines the firm’s investment growth effect following capital liberalization and financial constraints. It employs firm-level aggregated data of 80 firms for the period of 2006 to 2016. Employing the differenced dynamic panel regression technique, the analysis has revealed among others that investment growth appears to be significantly determined by cash flow (internal), thereby indicating the presence of profound financial constraint among firms in all industries. Second, the capital account liberalization appears to drive investment more through the indirect channel (capital/credit availability channel proxied by cash flow). Third, capital account liberalization-investment growth nexus appears to be less sensitive and significant with high profitability. This could be attributed to “profit flight” or repatriation of profit by foreign investors who may not necessarily prefer ploughing back of profit, which has implication for further expansion of investment among firms. This suggests that the level of capital openness is still low; hence, there is a need for further liberalization of the capital account with some mandate of profit ploughing back.

Introduction

The medical emergency team enables the limitation of patients’ progression to critical illness in the general ward. The early warning scoring system (EWS) is one of the criteria for medical emergency team activation; however, it is not a valid criterion to predict the prognosis of patients with MET activation.

Aim

In this study, the National Early Warning Score (NEWS) and Rapid Emergency Medicine Score (REMS) was compared with that of the Acute Physiology and Chronic Health Evaluation II (APACHE II) score in predicting the prognosis of patients who had been treated a medical emergency team.

Material and Methods

In this single-centre retrospective cohort study, patients treated by a medical emergency team between April 2013 and March 2019 and the 28-day prognosis of MET-activated patients were assessed using APACHE II, NEWS, and REMS.

Results

Of the 196 patients enrolled, 152 (77.5%) were men, and 44 (22.5%) were women. Their median age was 68 years (interquartile range: 57-76 years). The most common cause of medical emergency team activation was respiratory failure (43.4%). Univariate analysis showed that APACHE II score, NEWS, and REMS were associated with 28-day prognostic mortality. There was no significant difference in the area under the receiver operating characteristic curve of APACHE II (0.76), NEWS (0.67), and REMS (0.70); however, the sensitivity of NEWS (0.70) was superior to that of REMS (0.47).

Conclusion

NEWS is a more sensitive screening tool like APACHE II than REMS for predicting the prognosis of patients with medical emergency team activation. However, because the accuracy of NEWS was not sufficient compared with that of APACHE II score, it is necessary to develop a screening tool with higher sensitivity and accuracy that can be easily calculated at the bedside in the general ward.
Plasmapheresis in the Treatment of Refractory Myoclonic Status. A Case Report

A case of myoclonic status treated with plasmapheresis in a patient of 63 years of age who was admitted to a Spanish intensive care unit is reported. The patient showed clinical and radiological evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection; molecular tests did not verify this.
“You’re only a carrier” – women and the language of haemophilia
Authors: Chaplin Steve , Khair Kate
Published: November 2021

Women who have the gene variant for haemophilia are labelled solely as ‘carriers’ unless they have a factor VIII activity of ≤40%. This term, which describes an individual who can pass on a disorder but are themselves unaffected, reflects a legacy that extends from the 18th century to the present day. There is strong evidence that women labelled as carriers experience heavy periods, joint damage, pain and impaired quality of life. The label ‘carrier’ does not recognise this burden and is associated with guilt, stigma and difficulty accessing care. People living with a long-term disorder should now be described using person-first terminology and it is common to see the term ‘people with haemophilia’. The term ‘carrier’ should be limited to its application in genetics and not used as a catch-all label for women with haemophilia.
A new framework for ranking Critical Success Factors for International Construction Projects
Authors: Butković Lana Lovrenčić
Published: November 2021

Due to the wide range of opportunities, collaborations, and challenges offered by the international construction sector, interest in international construction is on the rise. Construction companies must be able to carry out international construction projects (ICPs) more effectively and efficiently. However, executing ICPs is more challenging than executing domestic construction projects. Considering the peculiarities of the construction industry and the associated complexity of construction projects, construction companies should decide on international capability and the selection of an ICP through a careful evaluation of their critical success factors (CSFs). Most of the previous research deals with the concept of CSFs in the context of project management in general, but few studies have identified CSFs for ICPs. To fill that gap in current research, the main objective of this study was to identify and group CSFs for ICPs. A total of 37 CSFs were identified after conducting a detailed literature review and a pre-pilot study. A new framework of CSFs for ICPs was proposed following primary research, which was conducted through in-depth interviews with leading experts in international projects. Although the constructability/complexity factor of the project received the highest rating in terms of importance to the success of the ICP, the next most critical factors were found to be external factors, such as local contractor/subcontractor, investor, and presence of a foreign partner. The results of this research may help participants involved in ICPs to improve their understanding of the international construction environment and deliver more successful ICPs.
Socioeconomia e gestão florestal no Projeto de Assentamento Moju I e II, Pará, Brasil
Authors: Bentes Antonio José Mota , Monteiro Raimunda Nonata , Vieira Thiago Almeida
Published: November 2021

Os assentamentos representam importantes territórios ocupados por agricultores familiares. Na Amazônia, dadas especificidades culturais, geográficas, de infraestrutura e ambientais, a sustentabilidade econômica, social, cultural e ambiental dos projetos de assentamento é mais exigente que em outras regiões do país.  A floresta, como um bem comunitário ou coletivo, pode representar um importante ecossistema a partir do uso sustentável, em prol da subsistência e qualidade de vida dos assentados. Assim, este artigo objetiva analisar o perfil socioeconômico dos assentados e a gestão florestal no Projeto de Assentamento Moju I e II, Oeste do Pará, Brasil. A insegurança das famílias nos lotes, somada à ausência de políticas públicas que promovam a floresta como um componente de desenvolvimento sustentável do assentamento, denota que a Reforma Agrária tenha se tornado um mero processo de distribuição de terras sem a promoção da qualidade de vida das famílias.
Theory: Leadership, Governance, Management, and Administration (Review of the Education Journal Articles in 2020)
Authors: Ngoc Hung Le , Trang Tran Thi , Nhan Cao Thi Thanh , Phuong Bui Thi
Published: November 2021

Based on the general systems theory, this study uses scoping method and bibliometrics to review 874 articles published in Vietnam’s  three educational journals in 2020. The article titles and abstracts with key words “theory, leadership, governance, management, administration” are selected and reviewed. The study tends to accept the hypothesis of “doctrine abundance, scientific theory shortage” in Vietnam’s educational research. The hypothesis of under-differentiation and confusion of leadership, governance, management and administration has also been accepted with the fact that there are the majority of articles on management and a few articles on leadership, governance, administration. Other finding is that most articles focus on internal elements including professional development, teaching and learning for cognitive objectives in systems of general education and tertiary education. Therefore, this study recommends to further do research and develop theories of educational sciences for all educational systems in general and preschool education and occupational education in particular. The research subject matter needs to cover external relationships between educational systems and environments. The objectives of comprehensive education should include ethical/moral, physical, aesthetic education harmonized with cognitive education to adapt to changes in the period of economic market conditions, international integration and digitalization.
