Published: September 2022

The aim of this study is to investigate the antihyperlipidimic effect of Terpenes fraction of Iraqi Cicer areitinum in high-fat diet (HFD)-fed mice. Animals were divided into four groups (n =8). The total duration of the study was 56 days split into two intervals. During the first 28-days interval, mice were administered with HFD, whereas during the second 28-days interval they were co-administered HFD plus Terpenes (500mg/kg: p.o.) or the standard drug Atorvastatin (10mg/kg:p.o.). Terpenes treatment to HFD-induced hyperlipidemic mice caused a high significant decrement in the levels of total cholesterol, triglycerides, LDL-C and VLDL-C. Moreover, Terpenes resulted in significant increase in the levels of HDL-C, whereas it caused remarkable decreases in ALT, AST and ALP enzymatic activities also in total serum bilirubin levels among hyperlipidemic mice. Besides that, Terpenes treatment showed significant improvement in levels of tissue MDA and GSH in hyperlipidemic mice. Histopathological examination of hyperlipidemic mice showed a disorganized hepatic tissue, marked and diffused cytoplasmic fatty infiltration which was all ameliorated by Terpenes administration. The results revealed that Terpenes (500mg/kg;p.o.) possess potential ameliorating benefits against hyperlipidemia induced by HFD on lipid profile, liver function enzymes, oxidative stress parameters and hepatic histo-architecture.

Published: September 2022

Laryngopharyngeal reflux (LPR) can contribute to chronic rhinosinusitis (CRS). Pepsin is believed to be one of the causes of CRS. Pepsin can be a promising biomarker because it is only produced by gastric parietal cells, so it can explain the correlation of CRS with LPR. This study aims to determine the relationship between CRS and LPR based on nasal pepsin examination. The design in this study is a cross-sectional prospective with statistical analysis using the Chi-square method. The research sample were patients with complaints of runny nose and nasal congestion within 12 weeks and met the inclusion and exclusion criteria. All samples were subjected to nasal endoscopy and fiber optic laryngoscope and have Reflux Symptoms Index (RSI) > 13. Specimens from the samples were obtained through the nasal washing method, and pepsin was evaluated using the PepTest lateral flow device. A total of 35 samples in this study consisted of 13 men (37.14%) and 22 women (62.85%). The highest age in the CRS group was the 18-40-year-old group with 16 (64%). A total of 20 (83.3%) CRS patients were positive for pepsin p=0.04 (p<0.05).

Diabetic foot ulcers are common complication in diabetics. This study aims to explore the effect of exercise on the risk of diabetic foot ulcers in diabetics using the Health Belief Model approach. One of the essential benefits of this study is to reduce the risk of developing diabetic foot ulcers, thereby reducing disability rates. The problem of diabetic foot ulcers can be prevented by implementing exercise interventions. In this experimental study, there were three groups, with 161 diabetics as respondents. Group one and group two were given different interventions, while group three was the control group. In this study, changes in the ankle-brachial index and the effect of Health Belief Model on activeness in the intervention were measured. Follow-up was done after three months of intervention. All aspects of the Health Belief Model scale were different in the three groups. Perceptions of obstacles showed the most significant difference (p=<0.001). All aspects of the Health Belief Model scale also affect the activity of diabetics in doing exercise (p=0.001). The results of the ankle-brachial index measurement showed that there were differences between the three groups (p=0.019) and the  “MULDA” exercise group had the highest median value.

Authors: Al-Mubasher Zakaria Mahmoud Abdullah
Published: September 2022

Background: Jordan is an Islamic country with a substantial percentage of its population belonging to the Muslim community. It teaches the younger generation Islamic knowledge (Malkawi, 2020). Islamic teaching consists of the preaching of the Quran, Sunnah, and Islamic history to the students. In Jordan, the three basics of Islamic education are given to children. However, with the surge of the COVID wave, the lockdown was imposed all around the country and education was made online. Online education did not satisfy teachers and students because of different issues including technical issues and social issues. Results: Analysing the response from the interview conducted, it can be said that mainly the technical issues faced by the teachers and students of Jordanian primary schools were mostly related to lagging and troubleshooting issues of the Dark application used by them to conduct online classes. Some of the difficulties were caused by distraction in a home environment, difficulty in accurate assessments of the students, no or less physical interaction, absence of practice-based learning and the lack of digital literacy. Conclusion: Since COVID-19 online education has been on the verge to rise in different parts of the world, including Jordan.

Published: September 2022

Background: This study aims to evaluate the value of adding elastography (strain elastography) to US in the evaluation of tendon abnormalities with comparison to conventional MRI. Methodology: After institutional review board approval and informed consent taken from all the patients, supraspinatus and tendoachillis tendon sonoelastography performed on 46 patients with shoulder or ankle pain and limitation of movement. Statistical analysis of this research was assessed by Chi-square test, Fisher’s exact test and Independent-Samples t-test. Results: This study included 46 patients with shoulder or ankle pain and limitation of movement, 23 male and 23 female patients. Their mean age (years) ± SD was 51.30 ± 12.4 years. We found that US had perfect agreement with MRI for detection of complete tear (k=1), strong agreement in diagnosis of partial tendon tear (k=0.810), while moderate agreement in detection of tendinopathy (k=0.645). Also we found that elastography increased US sensitivity and accuracy in diagnosis of partial tendon tear from (73.3% and 93.9% to 86.7% and 97% respectively) while it didn’t add any effect to US in diagnosis of complete tendon tear. Conclusion: Elastography plays an important role if added to US in evaluation of tendon abnormalities, especially if MRI is contraindicated for any reason.

Published: September 2022

Objectives: The study used three-dimensional finite element analysis to evaluate the effects of total deformation and Von Mises stresses (VMS) of different shaped non-carious cervical lesions (NCCLs) and occluso-gingival dimensions (OGD) of maxillary premolars when restored with different restorative materials. Methods: Maxillary premolar was scanned utilizing 3D-laser scanning to produce a 3D digital geometrical model. Six cavities were created with three different shapes (notch, saucer, and mixed), and two OGD (1.5mm and 3mm). Two 100N oblique forces were applied at 11o and 45o from the vertical axis. The total deformation data obtained were expressed in mm, and the VMS values were recorded. Results: Various tested dimensions and shapes of NCCLs produce equivalent values of maximum total deformation on restorations. Increasing oblique angle from 11º to 45º increased the total deformation about three times. Increasing oblique angle increase VMS by about 30%. One Bulk Fill restorative came in second with the lowest VMS. Ketacä N100 restoration had the longest lifetime. Conclusion: Various OGD shapes of NCCLs did not affect the restoration deformation or the values of VMS, whereas the loading angle and the type of restorative materials influenced the stress distribution in the cavity models of the maxillary premolars.

Published: September 2022

This research studies the sociological approach through a holistic pattern in solving the problem of homosexuality from the Qur’an perspective. This research is qualitative research that focuses on religious understanding as well as religious research. The conclusion of this research: First, the sociological approach through a holistic pattern in solving the problem of homosexuality from the Qur’an perspective is on attention, focus, objectives, and purposes in placing every individual. Second, according to the Qur’an perspective, the problem of homosexuality is an abomination (fâhisyah) because it deviates from the grand design of the creation of creatures in pairs between one gender and another. Thus, this problem must be handled based on a holistic pattern. Third, there are several factors that cause homosexuality. The experts are also not of the same opinion. Those several factors, among others: are biological, genetic and hormonal, psychodynamic, sociocultural, lack of religious understanding, education, family, and social life. Fourth, homosexuality gives negative impacts on health, education, faith, and social life such as venereal diseases, HIV/AIDS, and drug abuse. Fifth, the sociological approach through the holistic pattern from the Qur’an perspective applied in solving the problem of homosexuality covers the whole system: action, social, cultural, and personality.

Osteointegration is a direct structural relationship between the bone and the implant surface, a properly osseointegration implant can function without mobility. We aim to evaluate this process using serial radiological examinations, where characteristics such as bone sclerosis and cortical-periosteal thickening will be investigated. A retrospective analytic-observational study was conducted on 96 patients after cementless bipolar hemiarthroplasty operation from January 2012 to January 2021, examined for standing pelvic or hip anterior-posterior radiographs after six weeks, six months, and a year post-procedure at Surabaya Orthopaedic and Traumatology Hospital. Two musculoskeletal radiology consultants blindly evaluated for bone sclerosis, femoral stem positioning or stem angulation, cortical-periosteal thickening, and leg length discrepancy. The study was conducted on 24 male subjects (25%) and 72 female subjects (75%). Bone sclerosis significantly appeared in the six-month evaluation. There was no difference in femoral stem positioning. Cortical-periosteal thickening was found on the medial side according to the valgus position of the stem and began to appear in the 6-month evaluation and became more prominent after one year. No significant leg length discrepancy was found.
Aspects of Gothic Tradition in the Literary Imagination of Nnedi Okorafor
Authors: Sum Robert
Published: September 2022

The Gothic writing has often been perceived as a form of Western fiction- making. This apparently is based on the fact that Gothic genre originated in Europe in the late 18th century and has been widely exploited in the West (Europe and North America). Contrary to these assumptions, it can be confirmed that Gothic mode has indeed been appropriated by many non–Western fiction writers. An in- depth interrogation of Nnedi Okorafor’s, selected novels like ‘Who Fears death’, Akata Witch and The Book of Phoenix reveal that she does indeed appropriate Gothic elements. This article therefore critically examines aspects of Gothic tradition in Nnedi Okorafor’s selected novels. It seeks to portray how unique Gothic motifs like monstrosity, villainy and morality have been appropriated, transformed and complicated in Nnedi Okorafor’s selected novels ‘Who Fears death’, ‘Akata Witch’ and ‘The Book of Phoenix’. This study found out that that the three motifs indeed exist in Okorafor’s selected novels and are closely related. Gothic Monsters are generally implicated in subversion of social norms and nature. This often renders them villainous and their defeat, as portrayed in the analysed texts, leads to a restoration of moral order in a given society. Yet the findings affirm that physical or moral monstrosity of a character does not necessarily qualify her or him to be a villain. Villainy is tied to innate monstrosity which manifests itself through characters’ inhuman, unjust, and oppressive attitude towards the perceived other. This piece therefore concludes that Nnedi Okorafor does indeed appropriate the Gothic motifs of monstrosity, villainy and morality in a manner that offers radically fresh means of highlighting Africa’s complex reality.

Published: September 2022

This article evaluated the knowledge of Construction Waste Management (CWM) among contractors in Gqeberha and establish what legislative shortcomings were there in terms of CWM regulations. The reduction in landfilling could decrease the waste management cost for construction companies, and reduce negative impacts on the environment. This article used a qualitative design approach. The primary data was obtained through structured interviews from a selected number of main contractors in Gqeberha. The study focused on on-site agents, contracts managers, and Health Safety and Envronment officers through a nonprobability sampling technique. The study reveled that the lack of government legislation, to discourage the landfilling of waste, was the main catalyst. The primary data also stated that the lack of recycling facilities also contributed to the abundance of landfilling waste among contractors in Gqeberha. The research findings also showed that contractors in Gqeberha were knowledgeable on several construction waste management strategies. Future research will require contractors to research the potential economic benefits of CWM, as well as minimisation and recovery CWM strategies, and the local municipality to explore methods of discouraging landfilling waste, within the construction industry and in other sectors, as well as the economic and environmental benefits of CWM. The article provided insight concerning the CW and CWM practices among contractors in Gqeberha, including identifying the interventions required to address shortcomings.

The effect of Calcium and Sodium Intake on Bone Health
Authors: Wang Xinyi
Published: September 2022

Bone health gets more and more attention in the younger population since the peak bone mass will be achieved during one’s childhood and adolescence. Bone mineral density (BMD), an important indicator, is commonly used to indicate overall bone health. The development of BMD is critical during the growth period, which could contribute to less incidence of osteoporosis as people get old. Osteoporosis is one of the most common bone diseases, which could lead to other health complications. In addition to other factors affecting bone health such as physical activity and hormones, nutrition is the most important factor of bone health. Calcium (Ca) and vitamin D (VD) act hand in hand. The absorption of dietary calcium is highly affected by VD. Different hormones regulate Ca homeostasis and balance in the body. Moreover, bone remodeling is tightly regulated to conserve bone integrity. The bone formation is tightly coupled to the resorption. Dietary intake of sodium (Na) cannot be ignored as well. High intake of Na is negatively associated with bone health. The DASH diet with low sodium intake positively affects bone mineral density to some extent.
The Pathogenesis of Giardia Intestinalis
Authors: Li Xilin
Published: September 2022

Giardia intestinalis infection leads to intestinal cell damage and loss of the brush border of the intestinal epithelium, resulting in shortened microvilli and impaired epithelial barrier function. Watery diarrhoea, diarrhoea, nausea, abdominal pain, vomiting, and weight loss are all symptoms of this pathological alteration. Most infections are asymptomatic. Malnutrition absorption is the most common symptom of Giardia intestinalis infection. To treat Giardia intestinalis, several medications with good efficacy are employed, but the dose regimen is not always ideal, and the evolution of drug resistance is beginning to cast doubt on their clinical worth. In addition, some of these drugs can produce side effects that cause discomfort and make it difficult for patients to adhere to treatment. Giardia intestinalis is an important zoonotic parasite that causes diarrhoea in humans and many mammals. In recent years, its pathogenesis, including structural proteins and excretion of Giardia intestinalis, surface antigen variants, and the role of Giardia intestinalis in the small intestine, has been extensively studied. This article discusses this issue and lists the risks of Giardia intestinalis to the human intestine and the various diseases it can cause.
A Bayesian-based study on the average waiting time of airport taxis
Authors: Zhang Chen
Published: September 2022

In recent years, the incompatibility of airport taxis with passenger time, scale and other factors has led to the problem that airport taxi traffic is difficult to control. This topic starts from the perspective of the number of taxis in Zhengzhou Airport, uses Bayesian statistics and R implementation, applies Bayesian calculation to the analysis of the average waiting time of airport taxis, and establishes the Poisson distribution model of the actual airport taxi traffic flow and Exponential distribution model for waiting time. This topic clearly presents the influence of factors such as the number of passengers and the number of taxis on the average waiting time of taxis. The visual description of the airport taxi waiting time is realized by using R language. By analyzing the model from multiple angles, the model is solved and tested with data, and the model is evaluated and improved after the end. The results show that the taxi traffic flow Indeed, it obeys the Poisson distribution model with η as the parameter, and the average taxi waiting time obeys the exponential distribution model with λ as the parameter, and the posterior distributions of the two are gamma distribution and inverse gamma distribution respectively, which is the city taxi. Management provides basic theoretical tools.
Tree Search Algorithms For Chinese Chess
Authors: Heng Siyu
Published: September 2022

Computer Games are an important aspect of Artificial Intelligence (AI) which has produced many representative algorithms of optimal strategies. Therefore, many AI researchers have applied game theory to various board games in an attempt to find the essence of games and grasp the core of AI behaviour. AlphaGo is a very famous and typical chess-playing program that uses Monte Carlo tree search (MCTS) to estimate the value of each node in the search tree and optimize the possible results. Chinese chess is one of the traditional chess versions with its typical strategy. However, due to its late start and high complexity, there are many more technical problems to be solved. In this paper, we recommend two commonly used search frameworks for Chinese chess: the minimax algorithm and the alpha-beta pruning algorithm. On this basis, to deal with the complex and changeable situation, the Chinese chess algorithm based on Monte Carlo tree search and appropriate neural network evaluation function is studied.
Time Series Analysis for Air Pollution Data of Beijing
Authors: Li Jiasheng , Liu Huanshuo
Published: September 2022

For a long time, air pollution has been a serious problem encountered Beijing due to the city’s rapid economic development, high level social production and living standard, and unfavorable climate. This paper will use hour-by-hour data for six air pollutants and eight weather variables collected from January 1, 2014, to December 31, 2015, at an air pollution monitoring site in Beijing. We mainly analyze the data on SO2 pollutants with the ARIMA model which is used to make predictions on SO2 data. Since the periodicity of hour-by-hour data is too long and fluctuates drastically, using the ARIMA model will face problems such as lacking valid forecasting time and significant forecast bias. Besides, we have data on many climate indicators, including temperature, moderation, and concentration of many pollutants, which may be correlated. Therefore, with proper treatment, variable correlation analysis can assist us in predicting specific indicators. We use two different time series decomposition methods in the SO2 variable. The relationships between the periodic terms and air temperature and humidity were compared separately to verify the conclusions of some previous papers. Moreover, SCINet was used to predict and get excellent results.

Published: September 2022

With the development of 5G network, it becomes a hot topic to reasonably plan the siting of communication base stations in the weak coverage area of 5G network. In this paper, we take improving the coverage of service volume and reducing the cost of building base stations in the weak coverage area as the target of siting, and select base station sites among 2500×2500 points in a given area under ideal conditions and actual conditions, respectively, and use the less time-complex clustering method to cluster all weak coverage points. In order to improve the feasibility of the model in practical applications, we try to develop the base station site selection scheme that benefits the most for the 5G construction company by setting up a multi-objective planning model based on multiple constraints. On this basis, the conditions of the multi-objective planning model are changed and optimized to obtain a new multi-objective planning model based on the requirement that the communication coverage of base stations is fan-shaped in real life, and the simulated annealing optimization algorithm based on greedy thinking is used to optimize and solve the listed multi-objective planning model to obtain a new station site plan.
Media Bias Detecting based on Word Embedding
Authors: Geng Yihan
Published: September 2022

Machine learning research to detect political bias in articles has boomed in recent years. However, there is still no widely accepted and effective word embedding technique for detecting bias. This paper explores the connection between political bias and word embedding models and deduces factors to consider when selecting and developing word embedding techniques. Three classic word embedding models are introduced into experiments to conduct comparisons to achieve this goal. Contextual meaning is observed to lose efficiency in the task. In contrast, frequency is the most relevant feature in predicting media bias. Simultaneously, this paper discovers a unique accuracy distribution generated by Random Forest through experiments. Experiments reveal that it has apparent advantages in accuracy when predicting left-biased articles, which may relate to features undiscovered.
