Research Title: The effect of malnutrition on students' academic performance: Roy’s model application
Author: Mariam Mofleh Kawafha, Published Year: 2024
Nutrition and Food Science, 54
Faculty: Nursing
Abstract: Purpose
This study aims to enhance understanding of malnutrition's effect on academic achievement of primary school students.
Design/methodology/approach
This is a descriptive, cross-sectional design built on Roy's adaptation model (RAM). This study uses a random cluster sample, consisting of 453 primary school students. Contextual stimuli (mother's educational level, income and child’s breakfast eating) and focal stimuli (wasting, thinness, body mass index and stunting) were examined regarding adaptive responses to student’s academic achievement.
Findings
The investigation revealed that Model 1, which took into account factors of age, gender, the frequency of breakfast, income, the number of family members and the education of mothers, explained 12% (R2 = 0.12) of the variance in academic achievement. Stuntedness (β = −3.2 and p < 0.01), BMI (β = 0.94 and p < 0.001), family income per month (β = 5.60 and p < 0.001) and mother's education (β = 2.79 and p < 0.001) were the significant predictors in Model 2.
Practical implications
This study provides evidence that malnutrition is associated with ineffective academic achievement. Moreover, variables such as the mother's level of education, family income and the child’s breakfast consumption have a significant impact on academic achievements.
Originality/value
RAM is a useful framework for determining factors affecting people's reactions to difficult circumstances.

Research Title: Deep Learning-based Arabic Optical Character Recognition: A New Comprehensive Dataset at Character and Word Levels.
Author: Maram Bani Younes, Published Year: 2024
International Conference on Information and Communication Systems, Jordan
Faculty: Information Technology
Abstract: Optical character recognition (OCR) technology aims mainly to transform printed or handwritten text into machine-readable text. Recently, OCR technology has improved text scanning for various languages. It is widely used for digitizing physical documents, making them searchable and editable digitally. It aids in language learning and boosts business efficiency. However, attempts to apply OCR technology to Arabic texts face several challenges. This is because of the high complexity of its script, the cursive nature of Arabic characters, and contextual variations. Many Arabic OCR mechanisms have been developed in the literature. However, they suffer high error rates and issues of low accuracy. Then, an accurate OCR benefits the visually impaired, making content accessible via text-to-speech and braille displays is required. This work introduces a new dataset, MFSRHRD (Multiple Fonts, Sizes, Resources, High Records Dataset), containing sufficient records to ensure adequate training and correct learning of the model. This dataset gathers two types of words; the first includes words with diacritics, and the second includes words without diacritics. Besides, the new dataset contains images of the words collected from different specialized websites to ensure the diversity of the words and separate character images with and without diacritics. Therefore, the proposed dataset is classified at word and character levels. All these words and letters were drawn in different font styles, sizes, and image quality. The diacritical marks are dhamma, fatha, kasra, shade, and sukun. This work describes the detailed specifications of the proposed dataset intended for the research community.
Keywords: Arabic Optical Character Recognition (OCR), Arabic OCR datasets, Deep learning, MFRSHD, and Neural Networks.

Research Title: modelling and synthesis use of linear programming to generate tool paths for milling
Author: Hasan Abdel-Razzaq Al Dabbas, Published Year: 2024
Third International conference of Reliability of Engineering and Smart Energy (ICRESE), Istanbul
Faculty: Engineering and Technology
Abstract: The motion transmitted by a machine to both a tool and a workpiece being shaped, can be expressed by means of the fundamental kinematic cutting schemes [1, 8, 9 ]. As per the conventional fundamental kinematic cutting scheme, the movement of cutting elements of the tool relative to the surfaces of the workpiece being cut follows a path relative to working motion at speeds, predetermined by relations: the tool (T)–the workpiece (D).
When cutting the workpieces of any form in the simplest and shortest way possible the kinematics of cutting are represented as a combination of two basic motions: linear (straight line) and rotary [1]. In this case, both can be either primary or feeding, which is factored into different classifications of fundamental kinematic cutting schemes for cutting simple and complex shapes [1, 2, 8, 9].

Research Title: Novel anthraquinone amide derivatives as potential glyoxalase-I inhibitors
Author: Soha Telfah, Published Year: 2024
JOURNAL of MEDICINE and LIFE, 17
Faculty: Pharmacy
Abstract: This study aimed to identify novel Glyoxalase-I (Glo-I) inhibitors with potential anticancer properties, focusing on
anthraquinone amide-based derivatives. We synthesized a series of these derivatives and conducted in silico docking
studies to predict their binding interactions with Glo-I. In vitro assessments were performed to evaluate the anti-Glo-I
activity of the synthesized compounds. A comprehensive structure-activity relationship (SAR) analysis identified key
features responsible for specific binding affinities of anthraquinone amide-based derivatives to Glo-I. Additionally, a
100 ns molecular dynamics simulation assessed the stability of the most potent compound compared to a co-crystallized
ligand. Compound MQ3 demonstrated a remarkable inhibitory effect against Glo-I, with an IC50 concentration
of 1.45 μM. The inhibitory potency of MQ3 may be attributed to the catechol ring, amide functional group, and
anthraquinone moiety, collectively contributing to a strong binding affinity with Glo-I. Anthraquinone amide-based
derivatives exhibit substantial potential as Glo-I inhibitors with prospective anticancer activity. The exceptional inhibitory
efficacy of compound MQ3 indicates its potential as an effective anticancer agent. These findings underscore
the significance of anthraquinone amide-based derivatives as a novel class of compounds for cancer therapy, supporting
further research and advancements in targeting the Glo-I enzyme to combat cancer.

Research Title: Lower Respiratory Infections in Children With Febrile Neutropenic Leukemia: A Case in a Jordanian Hospital
Author: Nabil Nimer, Published Year: 2023
Clinical Pediatrics, 62 (11) 1342-1349
Faculty: Pharmacy
Abstract: The study aimed to examine the prevalence of pneumonia in pediatric children diagnosed with leukemia at King
Hussein Medical Center, Royal Medical Services, Amman, Jordan. The study was conducted from January 2019 to
March 2020. A total of 100 hospitalized leukemia patients with febrile neutropenic episodes were evaluated for
the presence of pneumonia. Samples were collected from all patients and tested for microbial growth. Univariate
analysis revealed that age (P = .033) and packed cell volume (P = .006) were statistically significant risk factors,
associated with the prevalence of pneumonia in leukemia patients with febrile neutropenia episodes. Similarly,
as the absolute neutrophil count counts increased with an odds ratio and a 95% confidence interval of 2.386
(0.859-6.625), the odds of pneumonia in febrile neutropenic patients were more prevalent. The study reported
the prevalence of pneumonia in immunocompromised febrile neutropenic patients with leukemia, which could lead
to the development of evidence-based febrile neutropenic treatment protocol development. It will assure more
responsive patient management and treatment.

Research Title: A Class of Bi-Univalent Functions in a Leaf-Like Domain Defined through Subordination via q-Calculus
Author: Abdullah Mohammed Khalid Al Soboh, Published Year: 2024
Mathematics MDPI, 12
Faculty: Science
Abstract: Bi-univalent functions associated with the leaf-like domain within open unit disk are
investigated, and a new subclass is introduced and studied in the research presented here. This is
achieved by applying the subordination principle for analytic functions in conjunction with q-calculus.
The class is proved to not be empty. By proving its existence, generalizations can be given to other
sets of functions. In addition, coefficient bounds are examined with a particular focus on |α2| and
|α3| coefficients, and Fekete–Szegö inequalities are estimated for the functions in this new class. To
support the conclusions, previous works are cited for confirmation.

Research Title: Towards optimal tuned machine learning techniques based vehicular traffic prediction for real roads scenarios
Author: Maram Bani Younes, Published Year: 2024
Ad hoc Networks, 161
Faculty: Information Technology
Abstract: Smart cities have been widely investigated, and several algorithms, techniques, and protocols have recently been developed to serve smart city environments. Intelligent traffic management is one of the main research fields in this area. It aims to control and monitor the traffic over downtown and highway scenarios. The real-time traffic characteristics on road networks highly affect safety conditions and driving behaviors. Detecting hazardous traffic conditions and congested areas early helps drivers make the best decision to avoid dangerous situations. After extensive training, machine learning algorithms are mainly used for prediction in this field. In the intelligent traffic control target, trained machines are beneficial in obtaining instant and accurate predictions regarding traffic congestion levels and their distributions. Several parameters control the efficiency of the selected machines. This includes the dataset quality, the regression algorithm’s parameters, and how they have been tuned. In this work, we first create high-quality datasets representing the moving vehicles for different main roads in various countries, including Bank St in Canada, North Rodeo Drive (NRD) in Los Angeles, USA, Queen Rania Al Abdullah (QRA) road in Jordan, and Sheikh Zayed Road (SZR) in Saudi Arabia. Then, we test the most popular regression algorithms and evaluate their performance in terms of temporal prediction of traffic characteristics and traffic congestion in different geographical road scenarios. We optimized these regression algorithms and tuned the used parameters using the grid search approach. After that, more advanced metaheuristic optimization algorithms were used to improve the prediction accuracy of the selected machine. Experimentally, we have proved the enhancements in predicting traffic characteristics for the tested road scenarios. Both approaches show enhanced results compared to using the regression algorithm without tuning the parameters. It shows advanced results for both approaches for the coefficient of determination measure, named R squared (
), with approximately 0.07, 0.04, and 0.08 enhanced values for Bank St., NRD, and SZR roads, respectively. In contrast, it shows approximately 0.95, 0.49, and 3.62 enhanced values for Bank St., NRD, and SZR roads, respectively, for the Root Mean Squared Error (
) measure.
