Authors: Sari Enna Berkah , Akbar Nizam Zikri , Hariman Herman
Published: August 2021

Background: Acute Coronary Syndrome (ACS) is a major cardiovascular problem because it causes high hospital admissions and mortality rates. Acute Coronary Syndrome is divided into 3 (three), namely: unstable angina pectoris (UAP), myocardial infarction without ST segment elevation (NSTEMI), and myocardial infarction with ST segment elevation (STEMI). In addition to changes in biomarkers of heart injury, the platelet index (IPF = immature platelet fraction) will also change the level difference between STEMI with NSTEMI/UAP.
Objective: To determine the differences in IPF levels of ACS patients with STEMI and NSTEMI/UAP
Method: Observational analytic with cross sectional approach. The subjects of this study were 80 patients who came to the emergency installation of integrated heart center Emergency Room Haji Adam Malik Hospital Medan from May 2019 to September 2019 and was diagnosed with ACS (STEMI or NSTEMI/UAP). The sample in the study was the patient's venous blood and put it in an EDTA tube, then immediately checked the IPF value/level using the automatic hematology analyzer. Patients with heart failure or patients with thrombocytopenia were not included in this study.
Results: In this study, the demographic characteristics of the ACS patients based on gender were male 77.5% STEMI and 87.5% NSTEMI/UAP while women 22.5% STEMI and 12.5% ​​NSTEMI/UAP. The results of the STEMI patient's IPF levels Compared with NSTEMI/UAP, the median is 6.2 (3.5-16.8) VS 2.9 (0.7-12) with a p-value of 0.0001.
Conclusion: The characteristics of ACS patients based on the results of sex were that there were more men with NSTEMI/UAP than those with STEMI. There was a significant difference in the IPF levels of STEMI with NSTEMI/UAP.

Twentieth century could be termed as the period when a renewed interest was seen in the Qur’ānic exegesis. Included in the long list of exegetes during this period are some women commentators of the Qur’ān, such as ‘Ā’ishah bint al-Shātī’ and Zaynab al-Ghazālī. This paper aims to analyze their commentaries of the Qur’ān, while focusing on their respective methodologies. A survey of ‘Ā’ishah’s commentary, al-Tafsīr al-Bayānī li ’l-Qur’ān al-Karīm, indicates that she focuses on the apparent meaning of the text of the Qur’ān and has tried to present the rhetorical and linguistic aspects of the verses (Āyāt) of the Qur’ān. On the other hand, Zaynab in her commentary, Naẓarāt fī Kitāb Allāh, primarily relies on the traditional methods of the Qur’ānic exegesis i.e., tafsīr bi ’l-riwāyah.

Considering the significant expenses with fertilizer and irrigation, the use of wastewater in fertirrigation has been studied as an alternative, since it can supply part of the water demand and provide nutrients to the plants. The objective of this work was to evaluate the changes in soil nutrient/pollutant contents, with successive applications of Domestic Sewage. Two treatments were implanted, one of them without alternation and another with alternation in the direction of the flow. Chemical and physicochemical analyzes of soil in the superficial layer were made in samples collected after 10 and 26 weeks from the beginning of application. According to the results, there was an increase in the Total Nitrogen, Sodium content available and in the electrical conductivity values, but a decrease in Potassium, Organic Matter and pH values. Although Total Nitrogen levels increased, they remained below the limit of risk. Potassium reduction can be explained by the high mobility in the soil and the absorption of plants. However, the reduction in the content of organic matter and in the pH value is due to the effect of the nutrient supply, which favored the degradation of the native organic matter of the soil.

Pedagogical knowledge (PK) can be understood as the set of educational analysis and instructional technics; and also, management strategies that primary teachers use to teach. For its assessment, a previously validated instrument to assess Pedagogical Content Knowledge, called CoRe, was used and a set of specific indicators (rubrics) were defined combining experts’ criteria and data analysis from an exploratory studio with preservice elementary teachers. Results showed the sufficiency of these rubrics to account for the variability of participants’ answers. Those indicators were used to analyze effects on PK from the instruction in general versus specific didactic in science. Results show an important contribution from specific didactic in science on preservice elementary teachers’ PK.

Dengue, zika virus and chicungunya are diseases transmitted by the bite of the female mosquito Aedes aegypti Linn. Because of this, these diseases pose a public health problem, especially in tropical countries. To date, there are no specific vaccines that act against the different serotypes of the disease. In this way, the measures adopted to combat it are restricted in the control of the mosquito. This is done using larvicide chemicals and insecticides, whose main component are organophosphorus, such as Temephos and pyrethroids. However, frequent use of these products has brought over the years some disadvantages: mosquito resistance, water contamination and attack on non-target living beings. Therefore, this work evaluated the larvicidal potential of the flower buds of the Syzygium aromaticum species against larvae in the third stage of the Aedes aegypti mosquito (Linnaeus, 1762). For this, the essential oil was quantitated by hydrodistillation. The physicochemical properties of the essential oil (density, refractive index, solubility, color and appearance) were determined. In addition, the oil was characterized chemically, quantifying its components and identifying its major component by gas chromatography coupled to mass spectrometry. The oil LC50 was calculated, in addition to the confidence limit at 95% probability, from the methods of Reed-Muench (1938) and Pizzi (1950), respectively. The yield of oil was 3.54% m / m and 3.63% v / m. Using the method used, it was possible to identify and quantify eugenol (52.53%), caryophyllene (37.25%), humulene (4.11%), eugenyl acetate (4.05%) and copaene %), With eugenol being the major component of the oil. The oil exhibited larvicidal activity being totally lethal at a concentration of 120 μg/mL.

Published: August 2021

Nanofluids have become nowadays of special importance because of their different uses in industry, therefore, to propose methods to calculate their thermal properties would be useful. In this work, a new variant for the calculation of thermal conductivity and diffusivity of nanofluids is proposed; the possibilities and limitations of this non-stationary method, which uses light radiation as the heat source, are studied. Here, the light is homogenously incident on one of the end surfaces of a cylinder that has a thermally insulated side surface, setting the temperature at the other end to a constant value, then the temperature distribution is obtained as a function of the coordinate and time; adjusting the theoretical model, parabolic heat diffusion equation, to the experimental data obtained. The conditions of validity of the method to measure thermal diffusivity and thermal conductivity of fluids are analyzed; as well as, the way in which it could be used to verify the validity of the Hamilton and Crosser (HC) model in the case of nanofluids. Currently, nanofluids are used to exchange heat, as they have been found to exceed the potential of conventional refrigerants; however, the calculation of thermal properties still does not offer definitive values.

The pesticide aldicarb is the most toxic active ingredient registered in all national territory, standing out for its extreme acute toxicity. In the environment, mainly in the water resources, several studies have demonstrated the potential of contamination of aldicarbe. The Paranaíba River cuts off the municipality of Itumbiara-GO, a region considered an important economic center in the south of the state. Along the Paranaíba River Basin there is a wide range of crops, such as sugarcane, corn, soy, cotton. This work aimed to quantitatively analyze the occurrence of aldicarb contamination in surface waters of the Paranaíba River, in addition to conducting a theoretical study of the river. For this purpose, the liquidliquid extraction with low temperature partitioning (LLE-LTP) and high-performance liquid chromatography (HPLC-UV) analysis were used. In the surface water samples of the river analyzed, no aldicarb contamination levels were found or the concentrations were below the detection limit of the LLE-LTP and HPLC-UV method.

Published: August 2021

The treatment of effluents is essential for the maintenance of the quality of water resources. Among the treatments used, photodegradation is on the rise. Although it is promising, the separation/recovery of photocatalysts in suspension is laborious and costly. In addition, the incorrect disposition of residues causes concern, for example, the glass originated from fluorescent lamps, which presents difficult destination and recovery. In this context, the objective of this work was to synthesize foam glass as substrate for the catalyst (ZnO), from glass residues of fluorescent lamps applying CaCO3 as foaming agent, observing the efficiency of this material in the photodegradation of Alizarin S dye in aqueous solution. To obtain the catalyst foam glass, the characterization was made on the glass and in the foaming agent, followed by its formulation, conformation and burning. Finally, the dye photodegradation tests were done. The results allow to conclude that the foam glass show a great potential as a support for ZnO in catalyzed photodegradation techniques, presenting very similar results when compared to suspended ZnO. It is worth mentioning that the material produced reduces the environmental impact caused by incorrect allocation of fluorescent lamps and solves a problem in the effluent treatment process.

Persistence and Change: Marriage and Family Among the Overseas Indians in the Caribbean
Authors: Jha Kiran
Published: August 2021

Indians came to the Caribbean under the system of indenture to augment the labour shortage in the plantations around the middle of the nineteenth century. Rather than returning after the contractual period, many Indians stayed on, accepting the Caribbean as their new found home. Thus began a symbiotic relationship of the Indian culture with the Caribbean society in the new habitat. This paper outlines the lives of the overseas Indians with reference to aspects of marriage, including the selection of spouses, different kinds of marriage and its dissolution. The paper also discusses the institution of family and its internal mechanisms in terms of patterns of authority, inheritance, conflicts, the position of women and the system of kinship. The overseas Indians moved from tradition to modernity, and from custom to legality. There was also resistance to change and deviations as some values struggled to be reinforced, while others were discarded. On the whole, kinship relations remained of vital importance for the sake of mutual cooperation and social intercourse in a foreign land. Interpersonal relations helped to regulate and standardize behaviour. In providing these accounts, this paper seeks to portray the persistence and change of traditional Indian social intuitions and customs among the overseas community in the Caribbean.

Published: August 2021

Objective: Patients with oral potentially malignant disorders (OPMDs) are at risk for development of malignancy and tobacco use contributes in its transformation. This study was designed to assess exfoliative cytological findings in OPMD cases using tobacco and healthy controls with no history of tobacco use. The aim was to screen OPMD cases for biopsy with the help of brush cytology.

Materials and Methods: This comparative cross-sectional study was conducted at Histopathology Laboratory of Peshawar Medical College, Peshawar for which samples were collected from two dental hospitals and private dental clinics of Peshawar. The study included 20 cases of clinically diagnosed Oral Potentially Malignant Disorders (OPMDs) with history of tobacco use; including 10 cases of leukoplakia and 10 cases of oral lichen planus (OLP), and 20 age and gender matched healthy controls with no history of tobacco use, after observing a strict inclusion and exclusion criteria. A pre-designed proforma was used to collect the data, which was later analyzed in SPSS version 21.

Results:  A total of 40 participants had a mean age of 48.25±10.01 years with gender distribution of 32(80%) males and 8(20%) females, giving a male to female ratio of 4:1. The duration of tobacco use in cases had a mean of 22.95 ± 9.17 years, while duration of lesion had a mean of 2.3±4.4 years. As per Oral Bethesda Criteria, 18 (90%) OPMD cases were Negative for Intraepithelial Lesion/Malignancy (NILM). Buccal mucosa 12(60%) was the most common site of lesions. On Oral Exfoliative Cytology (OEC), OPMDs showed mild to moderate cytological changes as compared to healthy controls.

Conclusion: This study concluded that most of the OPMD cases show mild to moderate cytological changes as compared to healthy controls. Dysplastic changes were seen only in 10% of OPMD cases that needed further assessment through biopsy.
The Greek tourism-led growth revisited: insights and prospects
Authors: Lolos Sarantis , Palaios Panagiotis , Papapetrou Evangelia
Published: August 2021

The paper investigates empirically the tourism-growth relationship in Greece, over the period 1960-2020. We find that the long-run relationship between tourism and output is positive and is characterized by a substantially faster convergence of output after a negative shock than after a positive one. Using asymmetric error-correction model analysis the results show that the short-term adjustment path occurs through the level of output for negative deviations from the long-run equilibrium, thus supporting the tourism-led growth hypothesis. Linear quantile regression analysis indicates that while the impact of tourism remains positive and significant across the output distribution it is stronger at lower quantiles of output than at higher ones. Our results have important policy implications, since the tourism-led growth hypothesis is a useful policy recommendation, but it should not be considered a cure-all policy.
Delitos sexuales: un enfoque médico legal

Published: August 2021

Human sexual behavior is a very complex matter that has been the subject of interesting studies throughout history. Sex is understood as the set of somatic, functional and psychic characteristics that distinguish a man from a woman. Sexual instinct, an hereditary derivation, is moderated and repressed by the intelligence and the conscious, in addition to being governed by the social norms of the environment in which the individual relates to others; on the other hand, there are those with behavioral problems that break all established rules. In the catalog of sex crimes in Mexico there are several criminal types: sexual abuse, rape, solicitation, sexual harassment, child molesting, among others, which can be prosecuted when they conjure the legal asset of the subjects of the crime, the typical norm, its material object and normative elements that may determine the unlawfulness and, consequently, the guilt, judicable by the authorship or participation. From a medical-legal standpoint, proving a crime of this nature represents a monumental challenge, because sometimes there isn't physical evidence manifested, and other times the nature of the circumstantial evidence does not help to determine whether or not a crime was committed.
Correctivos disciplinarios en las corporaciones de seguridad pública en México
Authors: Lomelí-Delgadillo Juan Gabriel
Published: August 2021

Disciplinary procedures comprised within the internal regulations of public security corporations in Mexico have long been used as ways of workplace terrorism by overseers who lack both the required preparation for their posts as well as the leadership to achieve goals that could be attained by other means, but their lack of empathy, obsession for shortterm goals and inexperience on the subject of crime prevention, combined with the inadequate training of new recruits, derive in the breeding of the submissive personnel that said overseers require to maintain their repressive working environment; that is to say, they groom their new employees to match their way of managing, creating robots that only obey and are unable to expose their bosses' incompetence.

This situation has paved the way for a disregard, in both the executive and the legislative branches, to rectify the mistakes made when it comes to the labor rights of those within public security corporations. The premise has always been to appoint the next “Security Guru”, and to follow blindly whichever road he chooses. Politicians in office have never been concerned with learning the least about public security strategies: they simply put their trust in whoever they appoint and defend their stance, as long as it doesn't backfire.

Les infections  sont responsables d'une part importante de la morbidité et de la mortalité chez l'enfant drépanocytaire. Notre objectif était d'étudier le profil clinique et bactériologique des infections bactériennes de l'enfant drépanocytaire dans le service de pédiatrie du CHU Gabriel Touré. Matériel et méthodes: Nous avons réalisé une étude rétrospective sur 25 dossiers d'hospitalisation d'enfants drépanocytaires fébriles ayant bénéficié d'une hémoculture sur une période de 5 ans (2005-2010). Nous avons analysé les caractéristiques cliniques et bactériologiques des enfants ayant une hémoculture positive. Résultats: Dix des 25 hémocultures réalisées étaient positives. La tranche d'âge de 0-5 ans était la plus touchée (60%). Le suivi était irrégulier pour 7 enfants et 6/10 n'avaient pas reçu le vaccin anti pneumococcique. Sur le plan clinique, 5 cas de sepsis, une infection pulmonaire et 4 cas infections ostéo articulaires ont été diagnostiquées. La goutte épaisse était positive pour 4 patients. Les germes retrouvés ont été : Salmonella enterica sérotype Typhi (4 fois), Streptococcus pneumoniae (4 fois), Staphylococcus aureus (1fois), Enterobacter cloacae (1fois) ont été isolés. Salmonella enterica sérotypeTyphia été isolé dans 3 cas d'infections ostéo-articulaires et un cas de sepsis, Streptococcus pneumoniae était en cause dans l'infection pulmonaire et dans un cas de sepsis. L'antibiothérapie probabiliste dans la majorité des cas était basée sur les céphalosporines de troisième génération. L'évolution a été favorable dans 80% des cas. Conclusion : Les complications infectieuses de la drépanocytose peuvent être graves. La disponibilité de l'hémoculture doit nous permettre de caractériser le profil bactériologique dans notre contexte.
Etude de l'implication du système d'efflux EmrAB dans la multirésistance chez Salmonella enterica Typhimuriu

Published: August 2021

Salmonella est un responsable majeur des cas de toxi-infection d'origine alimentaire. Malgré la diminution de l'incidence des salmonelloses ces dernières années, une augmentation du nombre des souches résistantes aux antibiotiques est observée. La résistance simultanée à plusieurs familles d'antibiotiques est particulièrement importante chez le sérotype Typhimurium de lysotype DT104. La résistance multiple est due à des mécanismes spécifiques associés et au mécanisme d'efflux actif plurispécifique. L'efflux permet à la bactérie de diminuer sa concentration intracellulaire en composés toxiques et ainsi de survivre dans un environnement hostile. Chez les entérobactéries, parmi les différents transporteurs identifiés, AcrB joue un rôle important dans la résistance multiple en fonctionnant en système d'efflux tripartite AcrAB-TolC. Cependant, chez S. Typhimurium, un autre transporteur que AcrB semble jouer un rôle important, en association avec TolC, dans la résistance aux sels biliaires. EmrB, un transporteur de la famille MFS pourrait jouer ce rôle, ainsi, des mutants inactivés au niveau du gène emrB et du gène codant le régulateur transcriptionnel, emrR ont été construits. Les tests de sensibilité aux antibiotiques et aux sels biliaires n'ont pas montré de différence significative entre la souche parentale et les mutants. La complémentation avec le gène emrB n'a pas permis d'amplifier le fragment attendu, pour chacun des clones testés.

Platônicos, aristotélicos ou sexistas? A metafísica implícita nas concepções geométricas associadas à produção de corações artificiais
Authors: Marini Marisol
Published: August 2021

O intuito é explorar as concepções matemáticas da natureza, a compreensão de que o suposto mundo natural manifesta-se por meio de códigos matemáticos, investigando os ecos desses argumentos na produção de dispositivos de assistência circulatória, chamados de corações artificiais. O ponto de partida é uma situação relativa ao exame de qualificação e resultados de pesquisa de uma das bioengenheiras da rede investigada, cuja tese justifica matematicamente a correlação entre o desenho das aletas (pás que fazem o rotor do dispositivo girar) a uma constante real algébrica extraída da Sequência de Fibonacci, conhecida também como proporção áurea ou divina. Trata-se de iluminar uma possível relação entre temáticas metafísicas associadas à perfeição, harmonia e beleza e o papel da feminilidade e a presença de mulheres na bioengenharia. O propósito não é reificar, naturalizar ou generalizar posições de gênero, mas explorar o papel estratégico da presença feminina num campo tido como masculino. Recuperando argumentos de Alexandre Koyré e dialogando com a hipótese de Edwin Burtt a respeito das bases metafísicas da ciência moderna o intuito é problematizar a emergência de argumentos metafísicos, a despeito do esforço de purificação construído ao longo de toda a história das ciências modernas e do desenvolvimento tecnológico
The feedback process: Perspectives of first and second year undergraduate students in the disciplines of education, health science and nursing

Published: August 2021

The purpose of this study was to determine the current perspectives of feedback from first and second year undergraduate students enrolled in blended units of study which incorporated both face-to-face and online components. Students enrolled in a unit of study taught by the School of Health Sciences at the University of Tasmania were surveyed to broadly determine their perception of the feedback process. Responses from the 55% of the cohort who completed the survey indicated that students recognised a wide variety of feedback processes in both written and online formats. Results indicated that students did not always identify that feedback (particularly formative) could feed forward to enhance their learning. There was a strong student focus on the importance of summative assessment feedback. The analysis of survey responses identified four main themes which form the focus of the discussion; types of feedback, student role in seeking feedback, the usefulness of feedback to learning and, feedback perception and awareness of students. The outcomes of this study also highlighted the necessity to educate both teaching staff and students with respect to feedback processes within the learning and teaching paradigm in higher education.
If you build it, they may not come: Why Australian university students do not take part in outbound mobility experiences.
Authors: Jones Benjamin , Power Anne , Gray Tonia , Downey Greg , Hall Timothy , Truong Son
Published: August 2021

Universities around the world seek to internationalise students to prepare them for an increasingly globalised world. Outbound mobility experiences (OMEs) are recognised as one of the most effective ways to foster independent thinking, cultural sensitivity, and a sense of ‘worldmindedness’. This article takes a case study from an Australian university and explores efforts to increase student participation rates in OMEs. Through a mixed-method study of three student cohorts (n=223), important data was gathered relating to how OMEs are perceived by undergraduate and post-graduate students. The results are filtered through thematic discourse analysis and suggest that the university needs to do more to build awareness, explain the professional and employability benefits, and create a travel culture where students are encouraged to grow their international skills and communication competencies. This research has important implications for universities seeking to increase international student mobility and prioritise a global outlook.
The Implementation of Sheltered Instructional Observation Protocol (SIOP) Model in Saudi Schools: A Study of EFL Teachers’ Perspectives
Authors: Aldakhil Ahlam , Alfadda Hind
Published: August 2021

The Sheltered Instructional Observation Protocol SIOP is a model designed to assist teachers in organizing and planning the lessons delivery through different stages. This model is also useful in enhancing the students’ achievement and minimizing any chance of educational failure. However, EFL teachers need to be trained in order to guarantee successful implementation of this model. This study examined the implementation of the SIOP model from teachers’ perspectives after they attended an introductory workshop in a private school in Riyadh city, Saudi Arabia. The study adopted the qualitative approach for collecting and analyzing the data. The sample of the study consisted of seven English language teachers (4 females & 3 males). Two data collection instruments were used, namely, observational sessions and a semi-structured interview. Most of the researcher interaction with the sample was done online due to the outbreak of Covid-19 pandemic. The workshop and the interviews were done through Zoom video communication. The central findings of this study reveal that the majority of the teachers have covered all SIOP components during their lessons. Moreover, it was found that there is a relationship between the implementation of the SIOP model and the students' learning motivation. Furthermore, the results showed that the SIOP implementation might help in enhancing the teachers’ proficiency. Besides, it was revealed that most of the teachers had a positive attitude towards the implementation of the SIOP model. However, they claimed that time and place might hinder any future implementation of the SIOP model. This study recommends a larger sample size, longtime study application and a life sample workshop to guarantee better results. It also provides significant implications which might be useful for EFL teachers, policy makers and interested researchers. 
Is the impact of the Economic Diversification on Economic Growth Symmetric or Asymmetric? Evidence from Saudi Arabia
Authors: Houfi Mohamed Ali
Published: August 2021

This paper presents our investigation of the impact of economic diversification on economic growth in Saudi Arabia for the 1990-2018 period. To this end, we used linear and nonlinear error-correction models (i.e., the ARDL, Pesaran et al. (2001), and NARDL, Shin et al. (2014), models) that are suited to capture the symmetric and asymmetric effects of economic diversification on economic growth based on the Solow model. As a measure of economic diversification, we used the Herfindahl index. In the linear and the nonlinear specifications, our results show that, economic diversification has a positive effect on the economic growth only in the long term. Furthermore, using the Wald test, the symmetric hypothesis in this relationship is not rejected, indicating that economic growth responds symmetrically to positive and negative changes in economic diversification. Our results also reveal that Saudi Arabia had relative success in achieving its goal of attaining a degree of economic diversification and enhancing its economic growth.
