The purpose of this study is to underline the progression and development of research regarding oxygen-containing heterocycles as well as the contribution that some oxygen-containing heterocycles have made as anticancer medicines. A series of publications about the antitumor effects of derivatives of heterocyclic compounds containing an oxygen atom, such as furan, benzofuran, oxazole, benzoxazole, and oxadiazole, were evaluated, and their anticancer activities showed encouraging results when compared to those of established standard treatments.

Background: a metabolic condition characterized by a failure in the metabolism of proteins, lipids, and carbohydrates that is brought on by problems with insulin production. When multiple autoantibodies, such as those against glutamic acid decarboxylase, are present against different insulin antigens, type 1 diabetes is present. Objective: To estimate the Glutamic Acid Decarboxylase Autoantibodies and assessment of HbA1c in type 1 DM. Methods: 40 children with diabetes participated, while 10 kids in the control group had blood sugar levels that were normal. HbA1c levels for each participant are measured as part of a quantitative ELISA test for the identification of circulating autoantibodies against glutamic acid decarboxylase in human serum. Results: All the pathological samples showed an increase in the concentration of Anti-GAD compared to the control. Samples of patients with diabetes for 5 years or more showed a decrease in Anti-GAD concentration compared to patients with diabetes for less than five years, but the decrease was not significant Conclusion: There was positive association between duration of type 1 Diabetes Mellitus and Glutamic Acid Decarboxylase Autoantibodies

Melanoma, the deadliest form of skin cancer, is on the rise. The goal of this study is to present a deep learning system implementation for the detection of melanoma lesions on a server equipped with a graphics processing unit (GPU). When applied by a dermatologist, the recommended method might aid in the early detection of this kind of skin cancer. Evidence shows that deep learning may be used in a variety of settings to successfully extract patterns from data such as signals and images. This research presents a convolution neural network–based strategy for identifying early-stage melanoma skin cancer. Images are input into a deep learning model known as a convolutional neural network (CNN) that has already been pre-trained. The CNN classifier, which is trained with large amounts of data, can discriminate between malignant and nonmalignant melanoma. The method's success in the lab bodes well for its potential to aid dermatologists in the early detection of melanoma. However, the experimental results show that the proposed technique excels beyond the state-of-the-art methods in terms of diagnostic accuracy.

We study a tropical linear regression problem consisting in finding the best approximation of a set of points by a tropical hyperplane. We establish a strong duality theorem, showing that the value of this problem coincides with the maximal radius of a Hilbert's ball included in a tropical polyhedron. We also show that this regression problem is polynomial-time equivalent to mean payoff games. We illustrate our results by solving an inverse problem from auction theory. In this setting, a tropical hyperplane represents the set of equilibrium prices. Tropical linear regression allows us to quantify the distance of a market to the set of equilibria, and infer secret preferences of a decision maker.

Polycystic ovary syndrome (PCOS) is receiving increasing attention, due to its association with many health troubles such as infertility and diabetes. The purpose of our study is to estimate the serum level of some indicators in women patients with PCOS. This study was conducted prospectively on 70 participating women who attended Al-Batool Teaching Hospital in Baquba (Iraq), with ages between (18-35) years, from February 2020 to November 2022. All the participating women were separative into two groups: )Control( group included 30 healthy women,and (PCOS) group included 40 women suffer from polycystic ovary syndrome. Ultrasound and analyzes of the sex hormones of the participants were used to confirm the detection of PCOS. Serological biomarkers were measured for both groups, including histidine, ferritin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin, and estrogen (E2). Results proven a notable reduction in the serum levels of hepcidin and FSH in PCOS group compared to healthy control group. In contrast, a considerable increases in levels of LH, prolactin, ferritin, and estrogen E2 hormone were observed in patients with PCOS. It was founded that these biochemical indicators may be a reliable diagnostic measure for polycystic ovary syndrome cases. Bangladesh Journal of Medical Science Vol.22 (Special Issue) 2023 p.4-9

What a genius, building a home for more than 10 centuries in the Sahara desert with all the necessary amenities to withstand a hyper-arid climate like that of Timimoun and Tiout. During our work missions during the period: 2000-2019 in the south-west of the Sahara, we were interested in the feeding of Timimoun ksours by the foggaras. This study shows that feeding ksar water remains an unresolved problem for the ksouriens of the Sahara. Two success stories in this area of water have been cited in this paper. These are the ksours of Timimoun which are fed by the foggaras. The ksar of Tiout was supplied with water by an ancestral dam. These are the two cases of the Sahara that have benefited from water with zero energy. These two examples demonstrate the ingenuity of the ksours population. If after ten centuries, the oasis have managed to master the architecture of the ksours, against the supply of ksar in water has shortcomings.

This paper focuses on Load distribution factors for horizontally curved composite concrete-steel girder bridges. The finite-element analysis software“SAP2000” is used to examine the key parameters that can influence the distribution factors for horizontally curved composite steelgirders. A parametric study is conducted to study the load distribution characteristics of such bridge system due to dead loading and AASHTO truck loading using finite elements method. The key parameters considered in this study are: span-to-radius of curvature ratio, span length, number of girders, girders spacing, number of lanes, and truck loading conditions. The results have shown that the curvature is the most critical factor which plays an important role in the design of curved girders in horizontally curved composite bridges. Span length, number of girders and girder spacing generally affect the values of the moment distribution factors. Moreover, present study reveals that AASHTO Guide criterion to treat curved bridges with limited curvature as straight one is conservative. Based on the data generated from the parametric study, sets of empirical equations are developed for the moment distribution factors for straight and curved steel I-girder bridges when subjected to the AASHTO truck loading and due to dead loading.

Resistance spot welding (RSW) aluminum alloys has a major problem of inconsistent quality from weld to weld, because of the problems of the non-uniform oxide layer. The high resistivity of the oxide causes strong heat released which influence significantly on the electrode lifetime and the weld quality. Much effort has been devoted experimentally to the study of the sheet surface characteristics for as-received sheet and surface pretreatment sheet by pickling in NaOH and glassblasted with three thicknesses (0.6, 1.0, and 1.5 mm) of AA1050. Three different welding process parameters energy setup as a low, medium, and high were carried. Tensile-shear strength tests were performed to indicate the weld quality. Moreover, microhardness tests, macro/micrographs, andSEM/EDS examinations were carried out to analyze, compare, and evaluate the effect of surface conditions on the weldability. The as received sheet showed a higher electrical contact resistance because of its thicker and non-uniform oxide layer. In contrast, the glass-blasted sheet showed lower value, since it has a roughest surface, which leads to easy breakdown the oxide layer. The highest average values and least scattering of the maximum load fracture are with treated sheet bypickling in NaOH, these values are 760, 1193, and 2283 N for 0.6, 1.0, and 1.5 mm sheet thickness respectively for medium input energy. In contrast, the minimum values with glass-blasted sheet are 616, 1008, and 2020 N for 0.6, 1.0, and 1.5 mm sheet. The microhardness profiles of the fusion zone and HAZ is the lower than the base metal for all cases. Numerical simulation with SORPAS® was used to simulate and optimize the process parameters, and it has given good results in prediction when they compared with experiments.

Fish drying is one of the traditional methods where the fishermen land their catch on the beaches for drying traditionally under sun for several days. Dried fish provides valuable and economical sources of animal protein. The quality of dried fish is significantly influenced by the presence of microorganisms. Therefore, this study aims to determine the physical quality changes in anchovy under three different solar drying methods which are open sun drying (OSD), solar greenhouse tunnel dryer (GTD), and forced convective solar dryer (FCD) and to verify the chemical and microbial contamination in solar-dried anchovy. About (20 kg) of fresh anchovy were taken for experiments. Quality analyses were conducted in the samples before, during, and after drying. The parameters analyzed included three main analyses which are physical, chemical, and microbial analyses. The drying rate was higher in GTD compared to the two other methods. Moisture content, drying rate, and moisture ratio were significantly affected by drying methods. GTD required less time (6 hr) to dry anchovies compared to other drying methods (9 hr time). The highest reduction in lightness is in GTD dried anchovies followed by FCD and OSD. The drying methods and drying time statistically affect the lightness (L) of dried anchovies ( p ≤ 0.05 ). The water activity of solar-dried anchovies was 0.3. Experimentally dried anchovies were found to have lower microbial count compared to the dried fish quality standards. The total viable count (TVC) in fresh anchovy was 6.44 log CFU/g compared to the greenhouse tunnel dryer 2.90 log CFU/g, open sun dryer 4.16 log CFU/g, and forced convective dryer 4.19 log CFU/g anchovies. Water activity and moisture content did not affect total viable count (TVC) significantly, but it affects total fungal count (TFC) ( p ≤ 0.05 ). There was a significant difference on Krusal Wallis between the samples of three methods of drying and a fresh one on the water activity, ash content, and fat content ( p ≤ 0.05 ).

Levaluation prenatale du pronostic postnatal des nouveau-nes porteurs de hernie de coupole diaphragmatique (HCD) sest amelioree au cours des cinq dernieres annees. Bien que les facteurs pronostiques utilises ne fassent pas lunanimite, il semble important que toutes les equipes utilisent les memes mesures afin de pouvoir comparer et ameliorer nos pratiques. Levaluation du pronostic se fera souvent a laide du Lung over Head Ratio (LHR) entre 22 et 28 SA ou du LHR observe/attendu (LHR o/a) quels que soient le terme, la position du foie et la mesure du volume pulmonaire a lIRM. Ces facteurs permettent de definir un groupe de fœtus porteurs de HCD de mauvais pronostic. Lorsque le LHR est inferieur a 1 ou le LHR o/a est inferieur a 25 % et le foie est dans le thorax, les chances de survie en periode neonatale sont de moins de 20 %. pour ce groupe, un traitement in utero peut etre propose. Un ballonnet peut etre place, entre 28 et 30 SA, par voie endoscopique dans la trachee fœtale et Il est retire vers 34 SA. Les premiers resultats montrent que le taux de survie de ces enfants passe de moins de 20 % a environ 50 %. Cette technique ne semble pas entraîner une majoration de la morbidite, mais cela est en cours devaluation.

Ovarian cancer is a growth of cells that forms in the ovaries. The cells multiply quickly and can invade and destroy healthy body tissue. Tumors of the ovary are remarkably varied as they may arise from any of the three cell types in the normal ovary. A retrospective study was conducted on 48 cases of ovarian specimens diagnosed as ovarian tumors in the Oncology department at Benghazi Medical Center from January 2020 to December 2021. The files were conducted by the staff members of the Oncology department, and the students divided themselves into groups to obtain the data from the department, the data were age, type of ovarian cancer, histological and cytological reports (microscopic description) and diagnosis. Twelve patients were in the age range 51-60 years old as the highest number followed by the age range 61-70 years of age at 11 patients. Most of the ovarian tumors were seen in patient in postmenopausal age more than 45 years of age with a percentage of 78.7%. Surface epithelial tumors were the most found at followed by metastatic tumors while germ cell tumors were not found in our sample. The most common subtype of ovarian tumors observed in this study was serous cystadenocarcinoma low grade and endometrioid adenocarcinoma, while the least common tumor seen was papillary mucinous cystadenocarcinoma. Concerning the occurrence of bilateral versus unilateral tumors, most of the cases were bilateral. The aim of our research was to study the histological types of ovarian cancer in Benghazi Medical Center in Benghazi - Libya from the years 2020-2021.

Biopolymers obtained from renewable resources became the center of public interest by virtue of their environmental and commercial advantages. Natural polymers such as starch, almond gum, chitosan and arabic gum were investigated to get fully or partially biodegradable dielectric material. Thus, in this article we study the material properties of cashew gum. This biopolymer is an exudate collected from occidental anacardium tree. For this investigation, scanning electron microscopy of powder and thin film cashew gum showed homogenous and slightly rough surface morphology with visible wrinkles. The thermal analyses such as thermogravimetric (TGA) and differential scanning calorimeter were realized. thermogravimetric thermogram shows two distinct stages of decomposition. The first around 150°C is attributed to moisture evaporation with loss in weight of 9.7%. The second transition, between 255°C and 330°C, is related to the decomposition of cashew gum with loss in weight of 50%. UV-visible spectra of the cashew gum thin film show a low absorbance and high transmittance. For this material, we obtained a direct optical band gap around 4.56 eV. In addition, the dielectric and electrical characterizations lead to conclude that cashew gum may be interesting for transistor applications as a gate dielectric.

By radical polymerization, two series of superabsorbent hydrogels of hydroxybutyl acrylate and acrylamide copolymers, poly(HBA-co-AAm), were obtained. In the first series, the ratio of hydroxybutyl acrylate to acrylamide was optimized with a constant amount of methylene bisacrylamide (MBA) as a cross-linking agent. In the second series, the amount of MBA was changed at a fixed monomer ratio. The structure of the copolymers was confirmed by the FTIR method. Swelling parameters and mechanical properties were tested. Hydrogels with a high Young’s modulus and a high degree of swelling were selected for the study of adsorption properties towards Co2+, Ni2+ and Cd2+ ions. The influence of basic factors such as adsorbent dose, exposure time and pH on adsorption efficiency was also investigated. The ability to adsorb heavy metal ions changed as follows: Co2+> Ni2+> Cd2+.

This study includes the preparation of the ferrite nanoparticles CuxCe0.3-XNi0.7Fe2O4 (where: x = 0, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3) using the sol-gel (auto combustion) method, and citric acid was used as a fuel for combustion. The results of the tests conducted by X-ray diffraction (XRD), emitting-field scanning electron microscopy (FE-SEM), energy-dispersive X-ray analyzer (EDX), and Vibration Sample Magnetic Device (VSM) showed that the compound has a face-centered cubic structure, and the lattice constant is increased with increasing Cu ion. On the other hand, the compound has apparent porosity and spherical particles, and there are no other elements other than those participating in the preparation of the compound, which means that it is of high purity. The prepared compound possesses excellent magnetic properties due to the narrowness of the magnetic hysteresis ring. The gas sensing system found that the compound has good sensitivity to H2S gas.

In this paper, Cr2O3 thin films were synthesized successfully on glass substrates at 450 °C using a simple and low-cost homemade pneumatic spray system (SP) using two different precursors: chromium chloride and chromium nitrate. A systematic study of the influence of concentration of each precursor used for deposition on the structural, morphological, optical and electrical properties has investigated. The XRD results show that the Cr2O3 films prepared with chromium chloride are polycrystalline with rhombohedral structure and those prepared with low concentration of chromium nitrate have a poor crystallinity. Peaks associated with Cr and O elements are present in EDS analysis that confirm the composition of the films and SEM images revealed a uniform, homogeneous and well covered surface. The measured electrical conductivity was found in the order of 5(Ω.cm)–1. The average transmittance of the films deposited from chromium nitrate is in the range of 60 % and for the films deposited from chromium chloride, it reaches75 % in the visible region. These electrical and optical properties of Cr2O3 thin film ascribed to its wide band gap, are indeed required for optoelectronic devices especially for solar cell window.

In 21st century business-mentality era, bank-services have been modernized where customers compete for comparative time-saving-options. However, many factors in services are unpredictable. Perceived-risk has been undermining the prospects of cashless-society country-wise such as Bangladesh. But banks should work eliminating issues particularly perceived risk by adopting Voluntary Insurance (VI) provision as proposed by Rahman (2018) in literature. Now using statistical techniques, this study examined customers’ opinions on VI as provision in e-banking services. Findings of this study show that customers’ “age group” and “education level” have preferences for enacting VI as Provision. Data statistics were collected from 200 respondents of city & rural areas of Bangladesh, which was used to test the mediated model using the Hierarchical Regression. The results have supported that the perceived-risk has acted as a partial mediator in the relationship between independent variables particularly psychological risk, trust, financial, performance, dispute, pin-fraud, social/ privacy-risk to dependent variable, that is, customers’ preferences for VI provision in e-banking services. Absolute risk-free services can attract more users of bank-led e-banking. Accordingly, policymakers can play vital role ensuring modern-society when it come e-banking services. Since digital transactions are not insured under Bank Laws in Bangladesh, like in other countries, this effort is for bringing the findings to the attentions of policymakers country-wise. Keywords: bank-led digital, perceived risk, voluntary insurance as banking-provision, risk-free digital-banking services

Background and ObjectivesRefugees and asylum seekers are at risk of head trauma. They endure blows to the head due to exigent circumstances necessitating resettlement (e.g., torture, war, interpersonal violence) and during their dangerous journeys to refuge. Our objective was to assess the global prevalence of head trauma in refugees and asylum seekers and describe its clinical characteristics in this population.MethodsThe protocol was registered in the PROSPERO International Prospective Register of Systematic Reviews (CRD42020173534). PubMed/MEDLINE, PsycInfo, Web of Science, Embase, and Google Scholar databases were searched for relevant studies. We included all studies in English that comprised refugees or asylum seekers of any age and examined the prevalence or characteristics of head trauma. We excluded studies that were not peer-reviewed original research. Information was recorded on the prevalence of head trauma, method of ascertaining head trauma, severity, mechanism of injury, other trauma exposures, and comorbidities. Descriptive analyses and narrative syntheses were performed.ResultsA total of 22 studies were included, of which 13 with 6,038 refugees and asylum seekers reported head trauma prevalence. Prevalence estimates ranged from 9% to 78%. Heterogeneity among studies precluded meta-analysis. Most studies were US based (n = 9, 41%), followed by the Middle East (n = 5, 23%). Most refugees or asylum seekers were from the Middle East (n = 9, 41%), with those from Latin America least represented (n = 3, 14%). Studies disproportionately involved younger (pooled mean age = 29 years) adult samples composed of men. Recruitment settings were predominantly hospitals/clinics (n = 14, 64%), followed by refugee camps (n = 3, 14%). The most common mechanism of injury was direct impact through a beating or blow to the head. Studies varied greatly in how head trauma was defined and ascertained; no study used a validated traumatic brain injury (TBI)–specific screening tool. Similarly, TBI severity was not uniformly assessed, although hospital-based samples captured more moderate-to-severe head injuries. Mental health comorbidities were more frequently documented rather than physical health ones. Only 2 studies included a comparison with local populations.DiscussionRefugees and asylum seekers are vulnerable to head trauma, but studies using systematic approaches to screening are lacking. Increased attention to head trauma in displaced populations will allow for optimizing equitable care for this growing vulnerable population.

Background: Blood is one of the most common clues found at crime scenes. Human blood is diagnosed according to the following context: first, the location of the blood spots, then virtual tests, then confirmatory tests. Genetic testing and serological testing are important tests in forensic medicine.. Materials and Methods: Thirty blood samples were collected in EDTA tubes, of which 25 were collected from humans and five from sheep. This study lasted five months from 23/3 to 22/8/2022. This study was conducted at Babylon University - College of Science - Department of Biology. The aim of this study was to evaluate the Hightop kit for detection of human blood. The blood was exposed to different weather conditions. Then it was examined using this kit to determine the ability of the antigen to withstand different conditions and the sensitivity of the measurement for this kit. Results: The positive results of blood stains that were exposed to different weather conditions for 30 days, except for blood stains that were placed on a smooth surface, showed negative results after 10 days of exposure, as opposed to those that were buried in the soil or blood stains on clothes that endured weather conditions for 30 days.. Conclusion: The Hightop kit is suitable in the field of forensic medicine to determine human blood that is exposed to harsh environmental conditions, as well as the ability to distinguish human blood from animal blood and its target antigen bears the weather conditions.

A three-dimensional investigation of mixed convection which occurs from Al2O3-water nanofluid flow in tube of a reduced solar collector and free convection in air gap situated between cover of solar collector and its absorber was investigated. Heat transmission by conduction in absorber and cover as well as thermal losses to exterior expressed in form of a convective flux have also been taken into account. The different transport equations were solved using CFD-Fluent software which is founded on finite volume method and Boussinesq’s law was introduced to take into account of buoyancy effects. In this investigation, thermal efficiency of solar collector was evaluated and use of nanofluids allows to increase this parameter which is generally low for this kind of thermal systems. Length of thermal regime established in the tube is proposed and this investigation is extended relative to other works developed in this research field. Results obtained gave an idea about the flow structure of the fluid under consideration in a tube of a solar collector and heat transmission mechanisms in air gap and in other elements of the solar collector. These results can facilitate design of this thermal system.

Moisture damage is one of the most significant troubles that destroy asphaltic pavement and reduces road serviceability. Recently, academics have noticed a trend to utilize fibers to enhance the efficiency of asphalt pavement. This research explores the effect of low-cost ceramic fiber, which has high tensile strength and a very high thermal insulation coefficient, on the asphalt mixture's characteristics by adding three different proportions (0.75%, 1.5%, and 2.25%). The Marshall test and the Tensile Strength Ratio Test (TSR) were utilized to describe the impact of ceramic fiber on the characteristics of Marshall and the moisture susceptibility of the hot mix asphalt mixture. The Field Emission Scanning Electron Microscopy (FE-SEM) analysis was used to investigate ceramic fibers' microscopic structure and clarify the mechanics of their improved behavior and their distribution within the asphalt concrete mixture. The results showed that the incorporation of ceramic fibers improved the Marshall properties and the asphalt mixture's susceptibility to moisture damage with an optimum fiber content equal to 1.5%, where Marshall stability increased by 39.04%, and the TSR increased by 11.06% at this content compared with the control asphalt mixture.

The magnetic and thermal properties of a ferrimagnetic mixed spin-1 and spin-2 cubic Ising nanowire are studied by using the Monte Carlo simulation. The influences of the nearest (JAB) and next-nearest neighbor (JA and JB) exchange interactions and the single-ion anisotropies (DA and DB) on the critical and compensation temperatures are illustrated. Moreover, the phase diagrams on the (temperature, anisotropy) plane are plotted for several values of JA/|JAB|. The system shows very rich and interesting behaviors, namely first and second order phase transitions, tricritical points and compensation phenomenon. Finally, the dependence of hysteresis loops on the anisotropies, the exchange interactions and the temperature is also investigated.

The Herlyn-Werner-Wunderlich syndrome (OHVIRA syndrome) is a rare urogenital malformation, characterized by a blind hemivagina, a didelphic uterus, and homolateral renal agenesis, it results from a defect in the development of the muller and Wolf ducts during the embryonic period, of unknown origin, the diagnosis is most often made at puberty during the first menstruation, sometimes late, particularly for non-obstructive forms: infertility or obstetrical complications, the diagnosis is based on pelvic ultrasound especially with 3D reconstructions and pelvic magnetic resonance imaging (MRI) which remains the standard gold for the detection of mullerian anomalies, laparoscopy can also play a double diagnostic and prognostic role in order to study the consequences of the blood reflection (hematosalpinx, inflammatory pelvis, endometriosis. In this work we report the case of an OHVIRA syndrome diagnosed late at the age of 36 years in a multiparous woman with acute pelvic pain simulating the picture of a torsion of the adnexa, we will discuss through this case the clinical, diagnostic and therapeutic aspects of this uterine malformation.

Recently, corrosion-inhibiting compounds have been discovered in a number of medications. In the past, corrosion inhibitors were used by researchers. Corrosion is a significant issue since it is difficult to eradicate completely. When metals interact with their surroundings, their chemical composition and physical properties change. Non-toxic antioxidants, such as organic and inorganic inhibitors, have been prohibited from use in corrosion prevention due to environmental concerns. Drugs can be utilized as corrosion inhibitors due to their minimal toxicity and impact on the environment. Corrosion inhibitors have been evaluated with a wide range of materials, including mild steel, carbon steel, and aluminum (melatonin, cephapirin and tramadol among them). By developing on the surface of mild steel, an insoluble compound has been discovered to inhibit corrosion. Because mass and charge transfer are blocked by the adsorption of modified dapsone medicine on mild steel, corrosion is inhibited. The corrosion inhibition was investigated using EFM, linear polarization resistance, and electrochemical impedance spectroscopy. XRD, SEM, and AFM techniques were utilized to evaluate the Metal surface morphology before to and following drug addition. Researchers discovered that expired Dapsone can be used to make a new corrosion inhibitor. According to an EIS investigation, during the inhibition phase, a charge transfer mechanism is at action. As the inhibitor concentration grew, so did the corrosion rate. Researchers used weight loss and electrochemical technologies to study the effect of cephapirin medications on carbon steel corrosion (CS). Density functional theory simulations revealed that cephapirin is an excellent carbon steel corrosion inhibitor (DFT).

The methods of detecting objects and tracking their movements are among the methods that are relied upon in many fields, whether medical or industrial, and others. One of these areas that will rely on deep learning meth-ods in discovering and distinguishing the player's movements is the sports field and is very useful in games in which the player's degree depends on the accura-cy of the performance of the movement, such as the gymnastics game, where it was applied to the static ring gymnastics game, where the distinction of move-ments was discovered the stability in this game is based on a convolutional neu-ral network. Models. The neural network was trained on five of the most im-portant stability movements in this game after creating the data set based on a set of videos of tournaments held in the period from 2016-2022, where an aver-age of 1500 images were obtained for each stability movement, which was di-vided into 80% for training and 20 % for testing, after training the convolution-al neural network model, it was applied to a group of video clips for different tournaments. Many criteria were adopted to measure the efficiency of the model after training and practical application, which showed the efficiency of the pro-posed system.

Cardiovascular diseases (CVDs) are the number one cause of death globally. Coronary artery disease (CAD) is the most common form of CVDs. Abundant research works propose decision support systems for CAD early detection. Most of proposed solutions have their origins in the realm of machine learning and datamining. This paper presents two solutions for CAD prediction. The first solution optimizes a random forest model (RFM) through hyperparameters tuning. The second solution uses a case-based reasoning (CBR) methodology. The CBR solution takes advantage of feature importance to improve the execution time of the retrieve step in the CBR cycle. The experimentations show that the RFM outperformed most recent published models for CAD diagnosis. By reducing the number of attributes, the CBR solution improves the execution time and also performs very well in terms of diagnosis accuracy. The performance of the CBR solution is intended to be enhanced because CBR is a learning methodology.

Oil and gas-producing countries are suffering from water resource depletion without any treatment or with technologies that have the same impact, regardless of how expensive or large a land area required. On the other hand, domestic wastewater also has many treatment technologies, and biological full cell is one of them. Using an end-of-tube hollow fiber membrane in domestic wastewater allows biological microorganisms to grout and treat the water, whereas using oil-filled water has not been studied so far. This study addresses the potential of biological growth on two different types of dead-end hollow fiber membranes by using three samples of oilfield water i.e., Membrane Aerated Biofilm Reactor OxyMem and MEMCOR® Ultrafiltration. The Membrane Bioreactor Systems are selected for the current studies and scanning electron microscopy (SEM) is used to show the biological growth on selected types of membrane to treat the oilfield wastewater. As a result, the growth in OxyMem is better which is 54% of COD removal and 55% NT removal for 55 days, whereas MEMCOR shows comparatively less growth in SEM results with 33% of COD removal and 9% NT removal during the same period. Therefore, this confirms that both types of membranes can be used to treat oilfield water in biological cells and noticed a better performance in OxyMem compared to MEMCOR.
