Following the exponential growth of information and communication technologies, the smartphone market, as well as advances in wireless data networks (3G and 4G), has accelerated. Mobile apps for social networking and instant messaging have been created by these firms. Other instant messaging (IM) smartphone programs like WhatsApp (WA), Viber, and IMO have also been created. WA is the most widely used instant messaging program. With WA, you can send and receive messages in a variety of formats, including text, voice, video, and documents. Various cybercrime incidents were committed through WA's. WA use leaves several artifacts that may be examined to detect the digital evidence. In addition, iOS and Android are two of the most popular smartphone operating systems. Because of this, the inquiry will involve the use of forensic investigative techniques and methodologies. Forensics on both iOS and Android cellphones were utilized to investigate a digital crime that was believed to have been perpetrated in WA. To conclude the investigation, we analyzed chat logs, phone records, and other media to gather proof. Legal framework and established processes were used to guarantee that evidence was preserved from change or destruction and that the witness's account was acceptable in court throughout the investigative process. It was finally stated that the inquiry and evidence had been presented. As a result, WA forensic artifacts might be evaluated and found effectively utilizing the mobile forensic procedure.

This study aimed to assess the potential association between nutrient intake and dyslipidemia in Jordanian pediatric patients diagnosed with type 1 diabetes mellitus.Methods: This cross-sectional study was conducted in Amman, Jordan, and involved 90 children and adolescents diagnosed with type 1 diabetes mellitus. Caregivers provided the following data: sex, age, type and dose of insulin, age at onset of type 1 diabetes, and level of physical activity. Anthropometric measurements were obtained using calibrated scales, and CDC growth charts were used to assess participants’ body weight status. Nutrient intake was estimated using a 120-item food frequency questionnaire (FFQ) previously validated in Jordanian children and adolescents. Serum lipid levels, including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C), were measured. Binary logistic regression was used to assess the relationship between nutrient intake and dyslipidemia.Results: The results indicated that 36.7% of study participants had dyslipidemia. There were no significant differences in nutrient intake between dyslipidemic and normolipidemic individuals, except for a significantly higher median intake of vitamin B12 in the dyslipidemic group compared to the normolipidemic group (3.6 versus 2.7 μg, P-value = 0.046).Conclusion: This study found no significant association between the prevalence of dyslipidemia and nutrient intake in children and adolescents diagnosed with type 1 diabetes mellitus.Keywords: nutrients, type 1 diabetes, dyslipidemia, children, adolescents

Online assessment is a new introduction in many developing countries during the COVID-19 pandemic, including Malaysia, Lithuania, and Spain. The current study conducted a phenomenology study to probe insights about fairness in online assessment. The interview data were interpreted from the perspective of social psychology theory that emphasizes distributional, procedural, and interaction justice. The study selected participants through purposive sampling techniques. Distributional justice revealed that grading seems fair when students experience multiple assessments, clear rubrics, and effective feedback from lecturers. In distributional justice students experience injustice when there are unclear expectations of assessment. Regarding procedural justice, students' unfairness was related to limited time, technical problems, and unclear assessment expectations. Interactional justice was related to privacy in communicating grades and weak interaction during the assessment. These results emphasize the importance of understanding the elements that influence students' views of fairness and methods to improve assessment during online assessment in a university setting.

One of the greatest challenges experienced by teachers teaching students who learn English as a foreign or a second language is teaching a class consisting of fast learners and slow learners commonly referred to as mixed-ability classes. The present study investigates challenges experienced by teachers of English language classes encompassing slow learners and fast learners. Data was collected using survey questionnaire and analyzed using Microsoft excel. Results revealed that teachers of English language experience several challenges: mixed-ability class tend to be uncooperative and fast learners get bored easily; challenges in planning for the lesson to teach a mixed-ability class; challenges in creating appropriate work-materials for the mixed-ability class; lack of best approaches to manage mixed-ability class; challenges in getting attention of all learners in a mixed-ability class; and frustration when teaching mixed-ability classroom due to low motivation of weak students.

Different Database management systems (DBMS) were developed and introduced to store and manipulate data. Microsoft SQL (MSSQL) Server one of the most popular relational DBMS used for large databases. With the increasing use of databases, intentional and unintentional accidents on databases are increasing dramatically.

In addition, the extended events another new feature introduced with MSSQL server 2008 for database performance troubleshooting. This study focused on DBFI in the MSSQL server using temporal tables and extended events artifacts. The experiment is conducted and the results have presented the use of the temporal tables and extended events artifacts in analyzing and determining the internal unauthorized modification on the database.

Most autism centers in Arabic countries rely on manual techniques in teaching children the basics of language, math, and social skills. Actually, these techniques may be limited in measuring the child's progress in a systematic way considering different fields. To overcome these limitations, we developed Autistic Innovative Assistant (AIA) which is an Android smartphone app that is dedicated to teach Arabic autistic children the necessary linguistic and mathematical basics in addition to improving their social skills through creating an interactive learning environment. The proposed app covers five main categories with an interactive quiz, included in each, as an assessment tool. The lessons included in each category are viewed as a series of colorful pictures with a written sentence and an audio message to describe the meaning of each, thereby attracting the child's attention and making learning a fun activity. Each child's supervisor can access his/her quizzes' records, measure the child's progress in different categories, and use the related recommendation reports to adjust the app usage pattern. AIA was tested by a group of autistic children for a one-month test period in a real life environment represented in "Jordan Specialized Center for Autism" and the results and feedback were very promising.

Abstract. With the rapid spread of technology in all sectors of life and the necessary need to increase the speed of payment processes, confidentiality, and privacy in business operations, cryptocurrencies appeared. The cryptocurrency is a virtual and intangible currency, in which transactions are made through the Internet and without any physical exchange between parties. These currencies are characterized by decentralization, transparency, privacy. Because transactions are carried out through a cryptography process and depend on Blockchain technology it is highly protected. Blockchain generally is a distributed ledger or a decentralized database. The Blockchain architecture combines advanced cryptography, distributed consensus mechanisms, and a complex system of incentives and rewards. In cryptocurrency, transactions are created, transferred, and verified through an integrated process called mining. Network members (network nodes) who carry out verification processes of transactions are called miners. As it is a credit or debit card used in banking transactions, in cryptocurrencies there is a so-called electronic wallet that is used for transactions that take place on cryptocurrencies over the Internet through computers or smartphones. Blockchain technology architecture has given cryptocurrencies many advantages and features that increase its strength and distinction from regular currencies and regular financial transactions such as decentralization, high confidentiality, anonymity, speed of transactions, very low fees, unlimited number of transactions, unrestricted by geography and borders, transparency, protection from Inflation, and the peer-to-peer network. The misuse of powerful features in cryptocurrencies and Blockchain technology has led to many disadvantages such as the risks of lack of knowledge, the lack of wide acceptance, the high risk of investing in them, its volatile nature, and the inability to return missing payments. This study concentrates on cryptocurrencies in terms of advantages and disadvantages.

Purpose Locally advanced rectal cancer (LARC) is managed by chemoradiotherapy (CRT), followed by surgery. Herein we reported patients with metastases during or after CRT. Methods Data of patients with LARC who received CRT from 2008 to 2017 were reviewed. Patients with metastases after CRT were included. Those with metastatic tumors at the initial diagnosis were excluded. Results Fourteen patients (1.3%) of 1,092 who received CRT presented with metastases. Magnetic resonance circumferential resection margin (mrCRM) and mesorectal lymph nodes (LNs) were positive in 12 patients (85.7%). Meanwhile, magnetic resonance extramural vascular invasion (mrEMVI) was positive in 10 patients (71.4%). Magnetic resonance tumor regression grade (mrTRG) 4 and mrTRG5 was detected in 5 and 1 patient respectively. Ten patients (71.4%) underwent combined surgery and 3 (21.4%) received palliative chemotherapy. Conclusion Patients with metastases after CRT showed a higher rate of positive mrCRM, mrEMVI, mesorectal LNs, and poor tumor response. Further studies with a large number of patients are necessary for better survival outcomes in LARC.

The rapid transformation from conventional vehicles to electric vehicles (EVs) holds promise for enhancing air quality, reducing CO2 emissions, revitalizing the renewable energy market, and enhancing countries' economies. This study investigated the performance of EVs in Jordan and the key challenges hindering their rapid development. It implemented a structured questionnaire of 202 EV owners/drivers and 15 interviews with technicians at many service centers. Findings revealed that Jordan leads among MENA countries in Battery Electric Vehicles(BEVs) market share and growth rate, with 52% market share of BEVs new cars in 2023, projected to surpass 80% by 2025. This rapid development is tied up with many internal and external influences; government backing, high fossil fuel prices, and tax exemptions are common causes that enhanced the market of EVs. Respondents highlighted prevalent issues of BEVs, including the rapid battery depletion, low battery capacity, electric inverter malfunctions, battery overheating, low performance in hot and cold climates, and inflating costs. Finally, this study recommends educational institutions to offer targeted training programs for EV maintenance and service, and the government should provide more incentives for this industry, and combat the influx of counterfeit charging accessories, batteries, and spare parts.

Herein two stacked nanosheets of lanthanum and silver coated by the thermal evaporation technique under a vacuum pressure of 10–5 mbar are used to form Ag2La compound. Ag2La thin films exhibited crystalline orthorhombic structure with lattice parameters, crystallite sizes and defect densities of a = 6.670 Å, b = 10.386 Å, c = 7.485 Å, 29 nm and 3.99 × 1011 lines/cm2, respectively. The films showed an indirect band gap of 3.25 eV. The band gap contained energy band tails of widths of 0.75 eV. In addition, the dielectric dispersion analyses on the Ag2La film have shown their excellent performance as high k dielectric materials displaying high dielectric constant value of 9.5 at incident light energy of 2.12 eV. On the other hand the optical conductivity and terahertz cutoff frequency spectral analyses have shown that Ag2La films have potentials applications in terahertz technology. The terahertz cutoff frequency varied in the range of 2–9 THz based on the driving light signal energy. As optical resonators they showed high sensitivity to visible and ultraviolet light signals. A respective high drift mobility of ~ 1.5 cm2/Vs and 44 cm2/Vs are estimated for the semitransparent Ag2La terahertz optical filters. The simplicity of producing Ag2La compound, the high dielectric constant values and the semiconducting characteristics of this compound make it attractive for high k-dielectric devices and for terahertz technology applications.

Naim Kittana,1 Mohyeddin Assali,2 Hanood Abu-Rass,1 Susanne Lutz,3,4 Rama Hindawi,2 Lina Ghannam,2 Marah Zakarneh,2 Ahmad Mousa1 1Department of Biomedical Sciences, Faculty of Medicine and Health Sciences, An-Najah National University, Nablus, Palestine; 2Department of Pharmacy, Faculty of Medicine and Health Sciences, An-Najah National University, Nablus, Palestine; 3Institute of Pharmacology and Toxicology, University Medical Center, Göttingen, Germany; 4German Center for Cardiovascular Research e.V., Partner Site, Göttingen, Germany Background: Impaired wound healing is commonly associated with many health problems, including diabetes, bedsores and extensive burns. In such cases, healing often takes a long time, which subjects patients to various complications. This study aims to investigate whether single-wall or multi-wall carbon nanotubes complexed with chitosan hydrogel can improve wound healing. Materials and methods: Initially, the effects of the complexes on the viability and functionality of fibroblasts were investigated in engineered connective tissues. Then, their activity on wound healing was investigated in a mouse model with induced full-thickness wounds, in which the wounds were treated daily with these complexes. Finally, the effect of the complexes on collagen deposition by fibroblasts was investigated in vitro. Results: The engineered connective tissue studies showed that fibroblasts were viable in the presence of the complexes and were still able to effectively organize and contract the extracellular matrix. In vivo data showed that both types of complexes improved the re-epithelialization of the healing wounds; however, they also increased the percentage of wounds with higher fibrosis. In particular, the chitosan-multi-wall carbon nanotube complex significantly enhanced the extensiveness of this fibrosis, which is in line with in vitro data showing a concentration-dependent enhancement of collage deposition by these complexes. These observations were associated with an increase in inflammatory signs in the wound bed. Conclusion: Single-wall and multi-wall carbon nanotubes complexed with chitosan improved the re-epithelialization of wounds, but an increase in fibrosis was detected. Keywords: carbon nanotubes, chitosan, wound healing, re-epithelialization, fibrosis, inflammation

Herein Ag2La thin films are fabricated by a vacuum coating method and subjected to a thermal annealing process. The thermally heated of films at 200 °C increased the crystallite sizes and improved the crystalline structure of the films. For these films the electrical conductivity measurements which were handled in the temperature range of 300-440 K. The conductivity analyses indicated that the transport of charged particles is dominated by the thermionic emission and by the variable range hopping conduction mechanisms. The annealing of films shifted the impurity levels and decreased; the degree of disorder, the average hopping distance and the average hopping energy. [ABSTRACT FROM AUTHOR]

This study aimed to explore the impact of a training program using elastic bands on selected physical and skill variables among volleyball players of Palestine Technical University - Kadoorie. Twenty male volleyball players were selected, their arithmetic average age was 20.45 years, and they were divided into two groups, (10) players for the pre-training test (control) and (10) players for the post-training test (experimental). The experimental group participated in an elastic band training program for two months. The data were analyzed using the statistical analysis program SPSS, and this was done by t-test to determine the differences between the pre- and post-measurements and the equivalence between the experimental and control group. The results indicated that there were statistically significant differences in the post-measurement between the experimental and control groups for selected physical and skill variables among the volleyball players, in favor of the experimental group. The percentage and p values of change in these measure variables tests were the Spiking (20.51%; p=0.011), Blocking (18.18%; p=0.001), Vertical Jump from Standstill (9.71%; p=0.033), Vertical Jump from Movement (5.37%; p=0.037), Medical Ball Throws from Overhead (2.81%; p=0.022), Medical Ball Throws from Chest (3.23%; p=0.001), and Push-Up (35.80%; p=0.001). This study concludes that elastic band training represents a promising evolution in the development of volleyball players, and is considered a comprehensive approach to improving their physical and skill attributes and enhancing their overall abilities on the court. This study recommended conducting additional research and applying elastic band training in the field of sports performance. [ABSTRACT FROM AUTHOR]

Background: Intra-tumoral CD8 + T-cell infiltration in squamous cell carcinoma of the head and neck (HNSCC) has previously been linked to the efficacy of cisplatin-based chemoradiation (CDDP-CRTX) and immune checkpoint inhibitor (ICI) monotherapy. Further detailed characterization of the tumor immune-micromilieu and its influence on outcome may guide the development of CRTX-ICI combinations. Methods: Comprehensive immune transcriptome analysis was applied to a training set of tumor specimens from oropharyngeal squamous cell carcinoma (OPSCC) patients treated with CDDP-CRTX in the ARO-0401 phase III study (n = 33). A composite immune signature risk score (ISRS) for survival prediction was developed, and subsequently validated in two independent OPSCC cohorts treated with either CDDP-CRTX (n = 36) or mitomycin-based CRTX (MMC-CRTX, n = 31). Further validation of the ISRS was performed in the OPSCC subset (n = 79) of the TCGA HNSCC cohort. Potential interference between immune signatures and HPV status was evaluated in multivariate Cox regression models. Results: Significant differences according to the 3-y OS status in the abundance of tumor-infiltrating T- and B-cells, and the expression levels of 51 immune-related genes were observed. A risk score based on 13 differentially expressed genes involved in cytokine signaling, T-cell effector functions and the TNFR pathway was established as robust predictive factor of OS. Its predictive power was superior to the 6-gene interferon-gamma signature of ICI efficacy and independent of the HPV status. Conclusions: This study further elucidates the complex interaction of the tumor immune microenvironment with the efficacy of CDDP-CRTX in OPSCC. The results suggest immune markers for selection of patients treated with CRTX-ICI combinations.

This study explored the multiple intelligence representation in the microcredentials designed by Malaysian educators and the reasons for integrating multiple intelligences in their course materials. The study was guided by the eight indicators of multiple intelligences suggested by Howard Gardner. We conducted in-depth qualitative interviews with 20 educators from a university in the northern region of Malaysia. The thematic analysis guided by Braun and Clarke shows a number of reasons why educators included the indicators in designing their content for micro-credential. Educators generally demonstrated that they used all the multiple intelligences indicators in designing the microcredentials. The findings are encouraging and suggest that all eight intelligences can be included in designing micro-credentials to enhance students' learning experiences with the help of technology. Finally, the authors suggest a pedagogical framework that can be considered by educators who intend to design the micro-credentials. [ABSTRACT FROM AUTHOR]

Introduction: Sex determination of unidentified human remains is very important in forensic medicine, medicolegal cases, and forensic anthropology. The mandible is the largest and hardest facial bone that commonly resists postmortem damage and forms an important source of personal identification. Additional studies have demonstrated the applicability of facial reconstruction using three-dimensional computed tomography scan (3D-CT) for the purpose of individual identification. Aim: To determine the sex of human mandible using metrical parameters by CT. Materials and Methods: The study included thirty subjects (15 males and 15 females), with age group ranging between 10 and 60 years obtained from the outpatient department of Oral Medicine and Radiology, Narsinhbhai Patel Dental College and Hospital. CT scan was performed on all the subjects, and the data obtained were reconstructed for 3D viewing. After obtaining 3D-CT scan, a total of seven mandibular measurements, i.e., gonial angle (G-angle), ramus length (Ramus-L), minimum ramus breadth and gonion-gnathion length (G-G-L), bigonial breadth, bicondylar breadth (BIC-Br), and coronoid length (CO-L) were measured; collected data were analyzed using SPSS statistical analysis program by Student's t-test. Results: The result of the study showed that out of seven parameters, G-angle, Ramus-L, G-G-L, BIC-Br, and CO-L showed a significant statistical difference (P < 0.05), with overall accuracy of 86% for males and 82% for females. Conclusion: Personal identification using mandible by conventional methods has already been proved but with variable efficacies. Advanced imaging modalities can aid in personal identification with much higher accuracy than conventional methods.
