The Use of English Placement Test (EPT) in Assessing the EFL Students’ Language Proficiency Level at a Saudi University
Authors:   English Department, Applied College for Girls, King Khalid University, Saudi Arabia, Sheerah Hebah Asaad Hamza , Yadav Meenakshi Sharma
Published: January 2023

Purpose: In order to ascertain EFL students’ characteristics (English proficiency, fluency, critical thinking, and communication), educational context, level of competence, professional goals, and pursuits for future endeavors, English Placement Tests (EPTs) are conducted in several academic contexts (Lamb, 2017; Ta?pinar & Külekçi, 2018; Stehle & Peters-Burton, 2019; Alrabai, 2021; Yuan, 2022). An EPT is a standard test used to determine students’ levels and abilities in English. It assesses how different their skills are in English before registering for English language courses in schools, universities, and companies. This research lends credence to the EPT’s reliability and validity in determining students’ course enrollment in university education. Design/methodology/approach: This study implemented a hybrid research design. At the start of the second semester in December 2021, 136 students took the placement test. A t-test was used to compare the students’ pre- and post-test results in order to assess the efficacy and effectiveness of the EPT. Five instructors also took part in a semi-structured interview to discuss their thoughts, beliefs, and experiences related to their teaching-learning enhancement of English programmes at the time the EPT was completed. Findings: The EPT results show students’ proficiency levels in three main areas: grammar, reading, and listening. After knowing the results of the EPT and the student’s performance, the weak areas were worked on. After one semester’s intervention, the test scores finally resulted positively, showing the students’ improvement. Since the results were statistically positive and significant, the study strongly suggested that EPT must be conducted at the beginning of the semester at the university level. Furthermore, based on the qualitative analysis and the comments and suggestions of the instructors, the idea of having an EPT for English foreign language (EFL) first-year students who want to take English language courses at universities was also strongly favored. The study supports the EPT’s validity for EFL students at college enrollment requirements according to English skills competency levels for English language courses.

bstract This study aimed to determine the number of cases, causes, and main rejection factors of Indonesia's fishery products by the USA and European markets. Data were obtained from the websites of USFDA (USA) and RASFF (Europe) from 2010 to 2020. Pareto analysis and fishbone diagram were used for analyzing data that informants validated from selected exporters and experts. Within the observed period, there were 2,318 cases of rejection in the USA and 79 in Europe. The highest case was in 2011 in the USA and 2012 in European markets. Based on Pareto analysis of rejection cases, the main factors that accounted for more than 80% of rejections in the USA were filthy and Salmonella; meanwhile, in Europe, were mercury, poor temperature control, Salmonella, histamine, and cadmium. The fishbone diagram result with validation from fishery product exporter shows that human factor, such as the lack of coordination and communication between business actors, especially at the supplier level when selecting raw materials, was considered the cause of rejection (filthy). Establishing well-managed cooperation among business actors within an integrated fish supply chain management is essential to ensure the quality of fishery products.

Alfisols have low fertility, so fertilization is carried out to increase soil fertility and support the growth of maize plants. The continuous use of inorganic fertilizers in high quantities can cause land degradation, so it is necessary to reduce the amount by adding other fertilizers, such as organic fertilizers, as well as the relatively high price of inorganic fertilizers. This research was aimed to examine the potential of organic fertilizers in replacing inorganic fertilizers. The experimental design was a completely randomized block design with nine combination treatments of organic and inorganic fertilizers with three replications. The results showed fertilizer treatment ½ NPK + 1 PO affected and increased levels of organic C, CEC, base saturation, total N, and available P in Alfisols and maize yield. However, it did not significantly affect pH, base saturation and available S in Alfisols. The chemical properties of the soil had increased values ​​of 48%, 9.01%, 61.3%, and 134.5%, respectively. The treatment of ½ NPK + 1 PO  increased maize productivity by 47.76% compared to the control with the productivity of 12.7 t ha-1, which the results were not significantly different from standard NPK. Thus, the application of 10 t ha-1 of organic fertilizer has the potential to replace ½ doses of inorganic fertilizer.

The review presents the prevalence of both type 2 diabetes mellitus (type 2 DM) and its microvascular complications among patients with coronary heart disease (CHD), and CHD among patients with carbohydrate metabolism disorders. It is shown, that the prognosis of patients with CHD and type 2 DM, especially in the presence of microvascular complications, is extremely unfavorable, and is characterized by a significant increase in the risk of cardiovascular death, myocardial infarction, stroke, terminal stage of the chronic kidney disease and visual impairment. It was noted, that despite the successes achieved in the treatment of CHD, type 2 DM and its microvascular complications, there is a high risk of total, cardiovascular mortality and hospitalizations associated with cardiovascular diseases. In type 2 DM, especially in the presence of microvascular complications and comorbid pathology, special pathogenetic mechanisms of thrombotic risk and bleeding have been identified. Based on large randomized clinical trials, the review evaluated the efficacy and safety of various antithrombotic strategies in patients with stable СРВ, type 2 DM in the presence of microvascular complications and comorbid pathology.
Comparison Analysis of Liquid and Air-cooling Systems for GPU
Authors: DV Prateeth
Published: January 2023

Abstract: In order to increase reliability and prevent early failure, heat produced by electronic components and circuits must be drained. Heat sinks, fans, and other air-cooling devices, as well as alternative computer cooling methods like liquid cooling, can all be used as heat dissipation techniques. Here the paper's main focus is on a numerical analysis of temperature distribution in a GPU scenario with various input velocity circumstances, including v = 1 m/s, 3 m/s, and 5 m/s. Air and water are the two distinct fluids employed in this investigation to cool the graphics card. An analysis of the fluid flow and heat transfer simulation of a desktop graphics card heat sink is conducted using the CFD software ANSYS Fluent. According to the findings, cooling with water was 10% more effective than cooling with air. The outcome also shows an inverse correlation between the graphic card chip's intake velocity and temperature. The rate of heat transfer to the heat sink increases as the inflow velocity rises which is helped by the convection.

Abstract: In today's world, automated tasks have made nearly everything we perform simpler. In an endeavour to concentrate on the road, drivers frequently overlook signs on the side of a road, which might be dangerous for them and nearby motorists. If there was an rapid means to inform the driver before causing them to change their focus, this problem may be avoided. If TSDR (Traffic Sign Detection and Recognition) identifies and understands signs in this circumstance, it may warn the driver of any impending signs. This not only ensures traffic safety, but also gives the driver peace of mind when traveling through uncharted or challenging roads. Not being able to interpret the sign's meaning is another significant problem. (Traffic Sign Recognition), which is a crucial element of modern driver assistance systems that contributes to driver safety, autonomous vehicle safety, and increased driving comfort. In comparison to previous decades, road conditions have vastly improved in today's globe. The vehicle's speed obviously increased. As a result, there may be opportunities for drivers to disregard necessary traffic signs while driving. This study investigates a systemIt helps drivers see traffic signs and prevent tragedies. TSR is a difficult process, and its accuracy is dependent on two factors: the feature extractor and the classifier.. To do both feature extraction and classification, most current popular algorithms use CNN (Convolutional Neural Network). In this work, we use CNN to the recognition of traffic signs. 43 unique traffic datasets will be used to build the CNN. Sign classes, as well as the TensorFlow library. The findings will indicate a 95% accuracy rate

Abstract: Traffic sign recognition is a driver assistance tool that can alert and warn the driver by showing any applicable limitations on the current stretch of road. Such limitations include signs such as 'traffic light approaching' or 'walking crossing.' The present research focuses on identifying Indian road and traffic signs in real time. Real-time footage from a moving automobile is captured by a computerized camera, and genuine traffic signs are retrieved using vision data. The network is divided into three stages: one for identification and the other for classification. The first stage created and constructed hybrid colour edge detection. In stage 2, a new and successful custom feature-based technique is used for the first time in a road sign identification strategy. Finally, a multilayer Convolution Neural Network (CNN) with Graphical User Interface (GUI) is being created to identify and analyse various traffic signals. It's tricky, despite the fact that it's been tested on both traditional and nontraffic signs and passed with flying colours..

Published: January 2023

El propósito del artículo consistió en realizar una revisión de algunas de las definiciones de Modernidad y Modernización y de las propuestas de su convergencia, con el fin de guiar los estudios de estos procesos en sociedades particulares, como las de América Latina, en las que desarrollo y atraso coexisten generando conflictos y desigualdad.

 

Se revisó las teorías de algunos autores contemporáneos especialmente de la sociología, así como las reflexiones de científicos sociales latinoamericanos provenientes de diferentes disciplinas, como la economía. Los criterios elegidos para seleccionar estas fuentes se soportaron en su riqueza explicativa y en la gama de indicadores que ofrecen para identificar e investigar la particularidad del cambio.

 

La revisión mostró que en las definiciones operativas de la modernización y en la manera como se manifiesta la superación de las tensiones entre este proceso de cambio y la modernidad se encuentran dimensiones e indicadores para investigarlos, analizarlos y caracterizarlos en este tipo de sociedades. También arrojó que las definiciones contemporáneas ofrecen una explicación limitada de su dinámica que mixtura diferentes velocidades y ritmos en un mismo tiempo y espacio.

Abstract: HIV infection continues to be a significant problem. Infected patients with HIV/AIDS were the first to show skin infections in the 1980s. It was projected that 35 million individuals would be infected with the Human Immunodeficiency Virus (HIV) in 2013. Before illnesses like diabetes and COPD, skin disorders were considered the 4th most common non-fatal disease burden globally in terms of years lost owing to disability. HIV-related skin disorders have a significant burden on society, have an adverse effect on the quality of life, and are directly linked to death. Pathophysiology of the disease is based mainly on understanding the pathology of the skin's immune system, as CD4 lymphocytes are considered the main key to the immunological response of the dermis and serve to inhibit autoimmune diseases and control infections. Hence, a massive decline is noticed in CD4 lymphocytes in patients diagnosed with HIV/AIDS, as mostly CD4 counts below 200 cells per cubic millimetre, which reveals the absence of immunity in the patients Because HIV-related skin problems are challenging to manage and might even reoccur more frequently than in immunocompetent people in the absence of immunological reconstitution with cART, managing them effectively presents unique challenges. Early detection of skin problems linked to HIV offers the chance for early HIV identification and cART introduction, potentially improving overall survivability. Additionally, in environments with low resources, attention is brought to opportunistic infections that are more likely to be fatal, and skin disorders may go unnoticed. This review aims to summarise current knowledge of pathophysiology, causes, and treatment of HIV-related skin disorders with the objective of more qualitative resources for further research, which contributes to better understanding and reveals the points that need further research.

Published: January 2023

Tilletia laevis cause common bunt and Tilletia controversa
cause dwarf bunt of wheat. Both pathogens can cause fungus galls which
replace with wheat grains and lead to the total loss of wheat yields. To
better understand disease progression, confocal microscopy was used to
construct the timeline of cell development of healthy wheat anthers, and
which was approved by analyzing the expression level of some
developmental and program cell death genes. Based on comparing with
normal healthy anthers, tapetum cells should be disappeared at 1300 µm,
but in T. laevis infected anthers, tapetum cells was visible in
2100 µm of T. controversa infected anthers. For the anthers
infected by T. laevis and T. controversa, cell size and
counts showed significant difference with normal anther cells.
Additionally, for the anthers of five developmental stages,
transcriptome profile and infected five developmental stages were also
analyzed. Furthermore, we established virus-induced gene silencing
(VIGS) for wheat bunt pathogens. Based on RNA-Seq data, TaEC in
wheat anther were validated to contribute to the resistance to both bunt
pathogens. This study firstly constructed the development timeline of
wheat anthers and firstly constructed VIGS system to explore the
interaction of both bunt pathogens with wheat anther development.

Whooping cough remains a life-threatening infection, especially for unvaccinated young children. The article describes a case of severe and non-smooth course of whooping cough in an unvaccinated girl of 4 months of life from the family hearth of whooping cough and COVID-19. There were cases of COVID-19 and whooping cough in adults in the family, occurring under the mask of a mild respiratory infection, not verified before they were detected in a child and did not require hospitalization. The combined course of two infectious diseases COVID-19 and whooping cough in a 4-monthold unvaccinated girl contributed to the prolongation of the duration of whooping cough, prolonged release of SARS-COV-2 RNA, the late appearance of hematological changes typical of whooping cough, the development of respiratory delays and re-hospitalization of a patient with prolonged respiratory support. In the context of the COVID-19 pandemic, the coverage of routine vaccination has significantly decreased, as a result of which children of the first years of life have become more vulnerable to vaccine-controlled infections, which causes the risk of combined infections.

Objective. To study the features of invasive aspergillosis (IA) due to A. non-fumigatus versus A. fumigatus in adult (≥ 18 years) recipients of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in 2016-2021.   Materials and methods. The study included 33 patients with IA caused by A. non-fumigatus (n = 20) and A. fumigatus (n = 13). A comparative analysis of cases of IA, the results of therapy and outcomes in patients after allo-HSCT in the RM Gorbacheva Research Institute was performed. Diagnostic criteria EORTC / MSGERC 2020 were used.   Results. Invasive aspergillosis caused by A. non-fumigatus made up the majority (60.6 %) of IA cases with an identified pathogen registered in patients after allo-HSCT in the period from 2016 to 2021. The main etiological agents in the A. non-fumigatus group were A. niger in 13 (65 %) patients, A. flavus – in 4 (20 %). The median day of diagnosis of A. non-fumigatus IAwas + 110 days (17–2093), for A. fumigatus it was + 46 days (2–866) (p = 0.171). Overall 12-week survival was 55 % and 59.2 % in the A. non-fumigatus and A. fumigatus groups, respectively (p = 0.617). The majority of patients in both the A. fumigatus (n = 10, 77 %) and A. non-fumigatus (n = 16, 80 %) groups received voriconazole as initial antifungal therapy. Second-linetherapy was required in 2 (10 %) patients with A. non-fumigatus IA: liposomal amphotericin B and echinocandins with or with-out posaconazole, and 2 (15 %) patients in the A. fumigatus group: liposomal amphotericin B and voriconazole in combination with echinocandins. A comparative analysis showed that in patients from the two groups, none of the assessed signs (gender, age, underlying disease, disease status at the time of transplantation, time from diagnosis to allo-HSCT, source of hematopoietic stem cells, conditioning regimen, donor type, antifungal prophylaxis, cytomegalovirus reactivation, severe acute and chronic graft-versus-host disease) did not differ significantly.   Conclusions. A. niger is the main causative agent of IA caused by A. non-fumigatus. Patients characteristics, their treatment and outcomes did not differ significantly between the A. non-fumigatus and A. fumigatus groups.

UreA is an important virulence factor of Helicobacter pylori that, along with UreB and UreC, produces urease. Urease enzyme helps the bacterium to colonize the human stomach through metabolizing urea in order to neutralize the gastric environment. The current study aimed to detect the prevalence of the H. pylori’s ureA virulence factor gene, and to investigate the influence of this gene on the result of the rapid urease test (RUT). Eighty stomach biopsy samples were isolated from participants who were suspected to be infected with H. pylori in Erbil city. Participants were 36 males and 44 females, aged between 18 and 67 years. The results showed that 42 (52.5%) of the participants were positive for H. pylori when tested by RUT, while 59 (73.8%) of the patients showed positive H. pylori infection when tested by polymerase chain reaction (PCR) targeting the 16S rRNA gene. The results of the PCR test based on the ureA gene revealed that 42 (52.5%) of the samples were positive. The important finding of this research is the presence of 100% compatibility between positive samples of RUT and ureA genes. It can be concluded from this study that a person may be infected with H. pylori, but the RUT test fails to detect the infection if the bacteria lack the ureA gene, indicating a direct impact of this gene on the result of RUT, which is a defect of RUT.

Published: January 2023

In this paper, we relied on historical observations for the period between (2005-2020) for the Baghdad meteorological station, which is characterized by a hot, dry climate in summer and cold and rainy in winter, as it is an example of a subtropical region. The multiple linear regression equation was developed and improved to produce a formula that predicts maximum air temperature. This was done by relying on climatic elements, namely minimum air temperature, wind speed, and relative humidity, and entering them into the formula as independent inputs that have a direct impact on estimating the maximum air temperature also calculating the correlation coefficients for each of them. The bias of the model was calculated and its value was entered as the correction for errors that accompany the application of the model.

Published: January 2023

This study aimed to investigate the multivariate relationship between the glycolytic potential, and meat quality traits from grass-fed steers carcasses with variations in early postmortem pH. From a contemporary group of steers (n=70) from the same production unit and slaughtered under similar conditions, thirty carcasses (10/group) were selected based on pH values measured at 3h (pH3h): Low (< 6.2), Intermediate pH3h (6.2–6.5), and High (> 6.5). Carcasses segregated by pH3h groups were different (p < 0.05) in muscular glycogen (MCG), glucose (G+G6P) content, glycolytic potential (GP) and GPstrict (GP without lactate content). The interaction pH3h groups × sampling time was significant only for lactate content (LC) (p < 0.05). Quality traits, except redness, did not vary (p > 0.05) among pH3h groups. Color variables had a positive and moderate correlation with MGC, G+G6P, LC, and GP. Results does not allow to recommend early carcass segregation by very early pH (3h postmortem); however, important bivariate and multivariate relationships between G+G6P, lactate content and instrumental color parameters in LL muscle from grass-fed cattle were demonstrated.

Visibility of articles is a key task for any peer-reviewed journal. It makes articles to be cited more likely thus helping journals to grow and to hold higher positions in international ranking systems. Like Elsevier company running the Scopus database, the Scilit database has been launched and is managing by another academic publishing company—MDPI (Basel, Switzerland). A Scilit name is a contraction of two words—scientific and literature. As a publishing house team, we are proud to receive inclusion of the Journal of Endodontic Microsurgery to its first database. Like other respected international open access English-language journals, among top priors of our Journal are listing in PubMed, Scopus, and Web of Science. For that purposes we will assist the editorial board of the Journal, helping to publish high quality articles in the field of endodontic microsurgery.
The economic valuation of ecosystem services: bibliometric analysis
Authors: Velasco-Muñoz Juan F. , Aznar-Sánchez José A. , Schoenemann Marina , López-Felices Belén
Published: January 2023

Research background: The services provided by ecosystems are the main support for human populations and for the development of any type of activity. Today, the provision of these services is under threat. The economic valuation of ecosystem services is vital to design appropriate policies, define strategies and manage ecosystems.
Purpose of the article: The objective of this study is to analyse the evolution of research on the economic valuation of ecosystem services over the last two decades. More specifically, it aims firstly to identify the main agents driving research and, secondly, it seeks to synthesize in a single document the relevant information on the main economic valuation methods, relating them to the categories of services, ecosystems and regions where they have been employed.
Methods: A quantitative review was first carried out through a bibliometric analysis to identify the main drivers of this line of research and its development trends. Secondly, a qualitative review was conducted through a systematic review focusing on the most commonly used valuation techniques in relation to the characteristics of the service, the geographical scope and the ecosystem analysed.
Findings & value added: The main novelty of this work, compared to previous literature, is that the relationship between the study area, the type of ecosystem, the category of service and the economic valuation methodology are analysed for the first time. The results highlight the need to continue expanding knowledge in relation to the temporal and spatial scale in the economic value of ecosystem services, the subjective nature of the estimates and the heterogeneity between the different social sectors with respect to the benefit obtained.
