Authors: Nascimento Alanderson Maxson Ferreira do , Sousa Joilson Silva de , Lima Neto Avelino Aldo de 
Published: October 2020

Com o intuito de colaborar com a emergência de novas fontes e objetos na historiografia da educação norte-rio-grandense, o presente trabalho busca analisar a Revista Som como fonte primária de pesquisa sobre a História da Música no estado entre as décadas de 1930 e 1940. A Revista Som foi um periódico especializado em música com circulação trimestral em Natal, lançada no ano de 1936. Seu objetivo era difundir e propagar os assuntos correlatos à educação musical, bem como, comunicar a produção artístico-musical da época, seja em âmbito local ou nacional. Ultrapassando as fronteiras do estado, sua circulação conseguiu alcançar outras regiões do país. No que concerne ao discurso historiográfico, nos valemos de uma interlocução com Barros (2017; 2019; 2020) e Zicman (1985) por suas considerações teórico-metodológicas relacionadas ao uso de fontes impressas, em específico a análise do periódico em tela. Neste trabalho analisamos os aspectos históricos da revista e seu papel enquanto fonte para a pesquisa em história da música no Rio Grande do Norte.

Abstract
One of the skills vocational education students must master in English courses is understanding the language of instruction or procedures in English. A total of 24 vocational education students at the Politeknik Negeri Lhokseumawe participated in filling out the questionnaires distributed online. Data were collected using the convenience sampling technique for two weeks from the date of August 26, 2020 until September 9, 2020. The data were analyzed qualitatively using the Miles and Huberman model. Data analysis consists of four stages, extensive coding, pattern coding, distilling and making propositions. The results showed that the majority of vocational education students at PNL were visual learners. The inclusion of pictures in the English instruction material is very helpful in understanding the text of the instructions given. Students prefer English instruction materials that are equipped with pictures rather than just pictures or just text. Students also use google translate to understand unfamiliar words to understand English instruction texts.

Extracting the Possible Intrinsic Relation between the Radiative Efficiency and Mass of QSOs: A Maximum Likelihood Method and its Application to the SDSS DR7 QSOs
Authors: Zhang Fupeng , Lu Youjun 
Published: October 2020

Abstract
Radiative efficiencies of QSOs and their distribution encode rich information on the evolution of both masses and spins of massive black holes (MBHs) across cosmic time. In this paper, we develop a maximum likelihood method to statistically extract the intrinsic relation between radiative efficiency (ϵ) and mass (M
•) of QSOs from their distribution on the luminosity–(empirically estimated virial) mass plane. By using mock samples, we find that strong constraint can be put on the ϵ–M
• relation at redshift z ≲ 0.4 from uniform QSO samples similar to those in the Sloan Digital Sky Survey (SDSS) and from QSO samples at z ∼ 0.6 (or ≲1.0) if the magnitude limit of the survey can be ∼1–2 (or 2–3) magnitude deeper. Applying this method to the SDSS DR7 QSOs with z ≲ 0.7, we find

(or

) correlation for QSOs with the masses obtained according to the H β (or Mg ii) empirical mass estimator. These contradictory results may be due to the unknown systematic errors in the two mass estimators, preventing an accurate constraint on the ϵ–M
• relation by using current available QSO samples. We find that both the estimates of MBH mass and Eddington ratio distribution functions can be affected by the ϵ–

relation, suggesting that the determination of this relation is important for understanding the accretion and growth history of MBHs. In the future, the intrinsic ϵ–M
• relation is expected to be strongly constrained by using QSO samples obtained from surveys deeper than the SDSS if the host galaxy contamination and systematic errors of the mass estimator(s) can be well modeled or removed.

Published: October 2020

Abstract
We present measurements of [Fe/H] and [α/Fe] for 128 individual red giant branch stars (RGB) in the stellar halo of M31, including its Giant Stellar Stream (GSS), obtained using spectral synthesis of low- and medium-resolution Keck/DEIMOS spectroscopy (

and 6000, respectively). We observed four fields in M31's stellar halo (at projected radii of 9, 18, 23, and 31 kpc), as well as two fields in the GSS (at 33 kpc). In combination with existing literature measurements, we have increased the sample size of [Fe/H] and [α/Fe] measurements from 101 to a total of 229 individual M31 RGB stars. From this sample, we investigate the chemical abundance properties of M31's inner halo, finding

and

. Between 8 and 34 kpc, the inner halo has a steep [Fe/H] gradient (−0.025 ± 0.002 dex kpc−1) and negligible [α/Fe] gradient, where substructure in the inner halo is systematically more metal-rich than the smooth component of the halo at a given projected distance. Although the chemical abundances of the inner stellar halo are largely inconsistent with that of present-day dwarf spheroidal (dSph) satellite galaxies of M31, we identified 22 RGB stars kinematically associated with the smooth component of the stellar halo that have chemical abundance patterns similar to M31 dSphs. We discuss formation scenarios for M31's halo, concluding that these dSph-like stars may have been accreted from galaxies of similar stellar mass and star formation history, or of higher stellar mass and similar star formation efficiency.

Abstract
We present a reanalysis of the cumulative ACIS-S Chandra data set pointed at the double active galactic nuclei (AGNs) of the NGC 6240 merging galaxy, focusing on the hard energy bands containing the hard spectral continuum (5.5–5.9 keV), the redshifted Fe i Kα line (6.0–6.4 keV), and the redshifted Fe xxv line (6.4–6.7 keV). We have used the full Chandra telescope angular resolution and modeled the Chandra point-spread function (PSF) by comparing a preflight calibration model to the data for the two bright AGNs. With two complementary approaches—(1) studying the residuals after PSF subtraction and (2) producing reconstructed Expectation through Markov Chain Monte Carlo (EMC2) images—we are able to resolve structures extending from ∼1 kpc to <200 pc in the S AGN. The latter are within the sphere of influence of this BH. We find significant extended emission in both continuum and Fe lines in the ∼2″ (∼1 kpc) region surrounding the nuclei, in the region between the N and S AGN, and in a sector of PA 120–210 deg. extending to the SE from the centroid of the S AGN surface brightness. The extended Fe i Kα emission is likely to originate from the fluorescence of X-ray photons interacting with dense molecular clouds, providing a complementary view to recent high-resolution Atacama Large Millimeter/submillimeter Array (ALMA) studies. The nonthermal emission is more prevalent in the region in between the two active X-ray nuclei and in the N AGN. We do not find strong evidence of X-ray emission associated with the third nucleus recently proposed for NGC 6240.

Published: October 2020

Introduction: Due to widespread inflammatory processes, often accompanied by pain and fever syndromes, NSAIDs are now the most prescribed drug group in the world. NSAIDs are characterized by taking a leading position in the number and severity of adverse actions. In recent decades, the efforts of scientists have been aimed at seaching for adequate ways to increase the safety profile of NSAIDs.
Materials and methods: In a series of experiments, the main objects of research were derivatives of α-cyanothioacet­amide – new tetrahydropyridones under laboratory codes TD 0364, TD 0353, TD 0351, CV 036, as well as hexahydro­quinolines CV 125 and OCO 5184. One promising area for searching for effective and safe pharmacological agents is some derivatives of α-cyanothioacetamide (CAS Number: 7357-70-2). The trigeminal orofacial pain test and the ther­mal tail immersion test were used to assess the analgesic effect. Determination of antipyretic activity was carried out on the yeast-fever model. To study an anti-inflammatory activity, the method of subacute non-infectious parotitis was used.
Results and discussion: The results of the experiment made it possible to find among the new samples of tetrahydro­pyridones and hexahydroquinolines the compounds with analgesic, anti-inflammatory and antipyretic activities, which, in terms of these types of activities in dynamics, surpass the reference (paracetamol, diclofenac sodium, and ketorolac). It is important that these compounds have low acute toxicity.
Conclusion: The consequence of the above is the necessity of further preclinical and clinical studies of samples of α-cyanothioacetamide derivatives in order to create new promising highly effective and safe drugs with analgesic, anti-inflammatory and antipyretic activities.
The Predictive Power of Baseline Hemoglobin for Transfusion Risk in Surgery Patients
Authors: Faris Philip M , Spence Richard K , Larholt Kay M , Sampson Allan R , Frei Dieter 
Published: October 2020

ABSTRACT
Preoperative hemoglobin concentration may be an important predictor of transfusion risk in surgical procedures with significant expected blood loss. Contemporary studies investigating transfusion risk with regard to the relationship between perioperative administration of Epoetin alfa and baseline hemoglobin provide data to test this hypothesis. The predictive power of seven preoperative variables (hemoglobin concentration, age, erythropoietin level, ferritin concentration, serum iron, total iron-binding capacity, and predicted blood volume) on transfusion risk was examined via retrospective logistic regression analysis of 276 orthopedic surgical patients. In the two studies used to perform the regression analysis, patients were treated daily with either Epoetin alfa or placebo. Based on the retrospective analyses, a prospective study was conducted to validate the hypothesis. Of the seven variables evaluated, baseline hemoglobin concentration and predicted blood volume were significantly predictive of transfusion risk in both Epoetin alfa- and placebo-treated patients. Further, an inverse correlation between hemoglobin concentration and transfusion risk was demonstrated in placebo-treated patients. Placebo-treated patients with hemoglobin > 10 to ≤ 13 g/dL had an approximately twofold greater risk of transfusion than patients with hemoglobin > 13 g/dL In contrast to placebo treatment, Epoetin alfa significantly reduced transfusion risk in patients with hemoglobin > 10 to ≤ 13 g/dL. Baseline hemoglobin concentration is an excellent predictor of transfusion risk in orthopedic surgical patients. As a result, hemoglobin testing should be considered a part of routine preoperative testing for orthopedic surgical patients.

-planes. We show that both the tropical variety of the Plücker ideal and familiar valuations associated to the construction of Newton–Okounkov bodies for the Grassmannian variety can be recovered from these compactifications. In this way, we unite various perspectives for constructing toric degenerations of flag varieties.

Published: October 2020

The Omani higher education system has enlarged noticeably since 1970 both in the number of students and in the infrastructure. As a result, there has been a big investment to provide quality higher educational institutes capable of providing suitable graduates to fulfill the requirements of the labor. The mean purpose of the higher education system is to provide the nation with the quality education that meets the requirements of the 21st century with graduates having readiness for employability skills and competencies. However, The skills gap between HEIs graduates and industrial requirements in Oman and other regional Gulf countries is seen as one of the most important factors that affect the employment of graduates in the private sector because the graduate readiness for employability did not consider the graduate attributes factors which influence graduate readiness for employability. Therefore, the main objective of the current study is to determine the effects of the graduates’ attributes on the readiness for employability and justified with existing theories in the higher educational institutes in Oman. Specifically, this study intends to determine the influencing factors that contribute to the readiness of Engineering Graduates for Employability in the Higher Education Institutes (HEIs) in Oman. The study reviews the current literature on the effects of graduates’ attributes on the readiness for employability especially for Omani engineering graduates as the main source of information. The study is designed to determine and analyze graduates’ attributes factors and elements. The literature utilized for this study covers the latest literature (from 2013 to 2019) extracted from Google Scholar, ProQuest, and Scopus. The four main keywords used were ‘higher education’, ‘graduate attributes ‘or ‘readiness for employability, and ‘skills gap and justify with most relevant theories in the particular area’. The study summarized the empirical review on the graduate attributes which analyses the effects of graduate attributes on the graduates’ readiness for employability that will be considered as an empirical study on the graduates of the engineering colleges in Oman. The study explored review findings on the graduate readiness for employability framework from different graduates’ attributes and provisions perspectives. The results of the study will fill the gap in understanding the main graduate attributes factors affecting the attainment of graduates’ readiness for employability skills which has justified with most relevant theories in the particular. The study also recommends a policy guideline for ensuring of readiness of engineering graduates for employability in the HEIs in Oman.

INFLUENCE OF SOCIALIZATION ON ACADEMIC PERFORMANCE OF LEARNERS WITH HEARING IMPAIRMENT AT INCLUSIVE PRIMARY SCHOOLS IN KENYA: A CASE IN THAWABU PRIMARY OF NAIROBI CITY COUNTY
Authors: Owuor Everlyne Achieng , Awori Beatrice Bunyasi , Otieno Syprine A. 
Published: October 2020

Purpose: This research aimed at determining the influence of socialization on performance of learners with hearing impairment at Thawabu Inclusive Public Primary School in Nairobi, Kenya. The objectives were to; establish modes of communication that promote socialization in an inclusive environment; establish strategies for boosting socialization to enhance academic performance; and establish challenges facing teachers in enhancing socialization to improve academic performance of learners with hearing impairment.
Methodology: The research design was a case study design. Structured questionnaires and interviews were used to collect data. Purposive sampling was employed to select the school and learners with hearing impairment while hearing learners were randomly selected.
Findings: The study found that: modes of communication among learners with hearing impairment, hearing learners and teachers create social and educational change for improvement of academic standards in the school and narrows the gap between those with hearing impairment and their hearing counterparts. Strategies like family support program (assisting children and families in language learning), family-infant-toddler program, and competent and consistent administration system promote learning. Socialization influences incidental learning of learners with hearing impairment to put them at par with their hearing peers on matters related to both academic performance and social advancement. Socialization makes learners with hearing impairment comfortable, self-esteemed, and self-actualized, hence improving educational performance.
Unique contribution to theory, practice and policy: The study may help to promote attitudinal, psychological and educational change in all stakeholders for inclusive education to be a success and meaningful to learners with hearing impairment. The study recommends that the government should add specially qualified teachers of learners with hearing impairment in Thawabu among other inclusive public schools in Kenya to help promote socialization and to increase inclusivity of leaners with hearing impairment.
