Perceptions of Academic Dishonesty: Insights from the University of Tehran
Authors: Shahghasemi Ehsan , Shirzadifard Maysam
Published: January 2024

In recent times, Iran has seen an increase in various forms of academic dishonesty. The frequency of academic fraud, plagiarism, and cheating has led to efforts to rebuild the global reputation of Iranian academic institutions. We argue that academic dishonesty adversely affects not only the academic sphere but society as a whole, and addressing it requires an understanding of its various contributing factors. To this end, we undertook a study involving students from three different faculties at the University of Tehran. The study included 300 undergraduate students (182 females and 118 males), aged between 17 to 34 years (average age 20.55, standard deviation 2.04), from the Faculty of Psychology and Educational Sciences, Faculty of Management, and Faculty of Social Sciences. While only minor differences were observed among students from these three faculties, significant variations were noted in the perceptions of academic dishonesty among students from different academic years, including their views on professors' and peers' dishonest behaviors, and the justifiability of academic dishonesty.
The Correlation between Poverty and Crime in Pakistan
Authors: TUNIO Fayaz Hussain
Published: January 2024

This scholarly article investigates the relationship between poverty and crime in Pakistan, a country facing significant poverty challenges with a substantial portion of its population living below the poverty line. The interconnection between poverty and crime is influenced by multiple factors, including feudalism, inflation, political corruption, population growth, an inadequate education system, and unsustainable utilization of natural resources, democratic deficits, and global economic variables. The rising crime rates not only jeopardize societal security but also generate an environment of fear and insecurity. To effectively address poverty-related crimes, it is crucial to establish a robust economic and social framework while implementing transparent policies for equitable resource allocation.

Authors: Mubarak Andi As'ad , Mahfuz Muhammad Ainul , Aziz Abdul , Dahlan Muhammad Sopiyudin
Published: January 2024

Objective: We wish to update existing meta-analyses to assess the effectiveness of pharmacological agents against ureteral stent-related symptoms with better design of RCTs, as well as more valid and reliable measurement methods. Material & Methods: Relevant published articles up to February 2022 were obtained from PubMed, CENTRAL, Google Scholar, Science Direct, and DOAJ. All single-blind or double-blind RCTs with various comparisons using pharmacological agents and/or placebo in patients with ureteral stent-related symptoms, with outcome assessment using USSQ at week 1 and week 4 during stent placement was included in the study. Statistical parameter Mean Difference (MD) with 95% CI was used to measure effect size. The p value less than 0.05 indicates statistical significance. Results: Alpha blockers (2 studies, 85 samples) significantly reduced fourth week UIS compared to placebo (MD: – 5.46, 95% CI: – 7.47 to -3.46, I2 = 0%, P = < 0.001), and alpha blockers (2 studies, 42 samples) significantly reduced first week SIS compared to combination therapy (MD: – 0.82, 95% CI: – 1.56 to – 0.08, I2 = 0%, P = 0.03). The results of the meta-analysis of USSQ scores in other domains have no significant differences. Conclusion: Alpha blockers were better than placebo in reducing UIS due to ureteral stent in the fourth week of stent placement, and better than combination therapy in reducing SIS due to ureteral stent in the first-week post stenting. However, more RCTs are needed with larger samples and better designs to reach valid conclusions.

Published: January 2024

The subject matter of this article is the processes of increasing information security in communication systems to solve applied problems that are critical in the transmission of confidential data. The goal is to develop a multi-stage method for protecting information from unauthorized access, based on probabilistic encryption integration, error-correcting code, and error decorrelation. The tasks to be solved are as follows: to develop a probabilistic encryption algorithm that considers the entropy of the characters’ appearance in a message; to implement iterative coding with variable parameters of the information bits matrix; and to implement error decorrelation based on the generated matrix by interleaving information and check bits according to a given algorithm. Methodology: theory of signal communication and signal processing, theory of cryptography, theory of noise-resistant codes, probability theory, statistical analysis. The following results were obtained: a multi-stage method for protecting information from unauthorized access was proposed, in which at each step of data conversion, information secrecy is increased; probabilistic encryption was implemented, which considers the entropy of a discrete source of information when forming a space of random combinations; based on an iterative code with specified matrix parameters, an additional increase in the space of random combinations was implemented; error decorrelation reduces the multiplicity of errors in codewords and ensures mixing of bits according to a predetermined law. Conclusions. The scientific novelty of the results obtained is as follows: 1) an improved method of information protection from unauthorized access is proposed, based on probabilistic encryption integration, interference-resistant coding, and error decorrelation; 2) increasing information concealment is realized by eliminating the main shortcomings of probabilistic encryption, which did not take into account the entropy of the symbols of the open message; 3) it is proposed to form the space of random combinations taking into account the average probability of the appearance of a symbol in open texts, which will allow the output of a probabilistic cipher to form a stream of random combinations, which, according to its statistical properties, is close to the uniform distribution law; 4) further development of information protection methods based on interference-resistant coding and error decorrelation with encryption functions is received; 5) a further development of the statistical encryption method is the use of all redundant elements for both probabilistic encryption and interference-resistant coding.
Morphological assessment of ovaries during stimulation of ovulation in rab-bits with equine serum gonadotropin in different doses
Authors: Tverdokhlib Yu. V.
Published: January 2024

Ovulatory stimulation of rabbits during artificial insemination requires the use of hormonal drugs to stimulate maturation of follicles, effective fertilization and full manifestation of female sexual function. For this purpose, gonadotropins or analogues of gonadotropin-releasing hormone are common in the practice of rabbit breeding. The latter have a selective effect on folliculogenesis and, under certain conditions, are not capable of inducing ovulation in rabbits of “zero” reproductive cycle, that is, those that have not given birth. Instead, gonadotropins, in particular serum gonadotropin obtained from foal mares (eCG), have a pronounced effect on folliculogenesis in animals. eCG is a glycoprotein hormone secreted by trophoblastic epithelial cells of fetal origin. In other species, except for horses, it is able to induce the release of both luteinizing and follicle-stimulating hormone. That is why eCG is widely used together with human chorionic gonadotropin to induce follicle growth and ovulation. However, there are data on complications and pathological conditions that may occur with long-term use of eCG, especially in genital tract. Therefore, the goal of our research was the morphological evaluation of the functional compartments of ovaries when using eCG to stimulate reproductive function of rabbits. Schemes of hormonal treatment of females in the conditions of a private rabbit farm, an experiment was conducted, which included the introduction of eCG in different doses (40 IU for animals of experimental group 1 and 25 IU for experimental group 2) during five reproductive cycles. Selection of material for histological studies, its fixation, production and analysis of tissue sections stained with hematoxylin and eosin were performed according to commonly used methods. The complex of morphofunctional changes in the ovaries of the rabbits of experimental groups corresponds to the pathomorphological picture of the syndrome of hyperstimulated ovaries. In our experiment, obtained changes were more pronounced at a dose of 40 IU, using which we additionally detected signs of increased immunoreactivity in body of rabbits, as evidenced by the presence of nodular lymphoid formations in outer theca of secondary and tertiary follicles. Thus, as a safe regimen for the use of eCG for ovulatory stimulation in rabbits, we recommend a dosage of 25 IU for 1–2 reproductive cycles.

The market situation regarding the breeding of decorative dogs of the Pomeranian breed and providing consumers with appropriate services in this field of activity dictate the rules and create the conditions of competition between market participants, which encourages improvement, development, and constant monitoring of it in terms of novelties and needs that provide opportunities for comfortable care and decent maintenance of pupils. The work aimed to analyze the impact of sanitary and hygienic factors and ensuring healthy housing conditions on the functional state of the body and mental health of Pomeranian Spitz dogs in the conditions of the private breeding kennel Fluffy Luxury Pom in the suburbs of Lviv. To fulfill this task, a study of the hygienic parameters of the air environment, compliance with the hygiene of feeding and drinking of the wards, peculiarities of the care of the wool coat, and compliance with the concept of animal welfare – the principle of “Five Freedoms” was carried out. It has been established that the technological solutions for keeping Pomeranian Spitz dogs in the conditions of this kennel are characterized by compliance with hygienic requirements for the air environment at the proper level and meeting sanitary standards. Thus, the air temperature was 17 °C, and its movement speed was 0.15 m/s. In the absence of the smell of ammonia, the illuminance ratio corresponded to 1:2. The animals are fed with industrial complete ration super premium 1st Choice feed, the use of which, according to recommendations, helps dogs strengthen the immune system, slow down the aging process, maintain health and activity. This type of food requires constant free access of dogs to clean water, and the containers are kept clean by changing the filling every day. Regarding the quality characteristics of the water, it was established that it fully meets the standard. Dogs of this breed are characterized by a beautiful, lush coat requiring special care. Evaluating the level of compliance with individual hygienic procedures, it was established that they are carried out at a high level, as evidenced by the appearance of the animals. According to the statements of John Webster, the welfare of animals is defined by advocating the main three conditions - to live a natural life, to be healthy, and to be happy. The dogs in this kennel are provided with a good life; the behavioral reactions of the wards themselves confirm this. During the research, the dogs behaved calmly, naturally, and playfully, which indicates the socialization of dogs; the purpose is to make the pet feel comfortable and calm in various life situations without causing trouble to its owner and his surroundings.

On the Effective Concrete Compressive Strength in the Theory of Plasticity
Authors: Windisch Andor
Published: January 2024

In his fundamental book Nielsen (1984) summarized the basics of application of plastic theories to the design of concrete structures. Since that time extended experimental and theoretical works were carried out. Models based on plastic theories were developed for bending, shear, for beams, plates, etc. The strut-andtie-, the stress field models and the Modified Compression Field Theory perform further developments of application of the theory of plasticity. Crucial point (the governing material characteristic) of these models is the effective concrete compressive strength. This paper critically reviews its different theoretical origins and despairs of its existence. It reveals that the main source of plastic behavior of structural concrete structures is the reinforcement. In design for shear instead of a preposterous effective concrete strength the effective web thickness and (a maybe slightly reduced) concrete compressive strength should be taken into account. Neither the concrete compressive strength nor any reduced (effective) value of it are applicable as governing material characteristic of any plasticity model for structural concrete structures.

Published: January 2024

Every year, cardiovascular disease (CVD) claims the lives of nearly 17 million people worldwide. Predicting heart disease early and accurately can help delay therapies and improve results. Patient data analysis machine learning techniques have shown promise for better predictive capabilities than conventional methods; however, there are still gaps in areas such as algorithm blending, standardization, feature optimization, and model tuning that require strong methodology. By benchmarking against established methods, this study attempts to create a more sophisticated machine learning model with detailed performance and a robust approach for predicting heart disease. Using a clinical dataset that was obtained from an internet repository, an improved random forest (RF) model was created. It was then tested against baseline logistic regression and support vector machine models, Naïve Bayes Classifier, K Nearest Neighbors Classifier, and Decision Tree Classifier. RF hyperparameter tweaking, redundant feature filtering, and systematic data preprocessing were used. Accuracy, precision, recall, F1 score, and ROC analysis were computed as evaluation measures. With F1 score, 1.00 AUC, and 90% accuracy, The RF model demonstrated superior performance compared to the remaining models, which exhibited, AUCs of 0.9, 0.82, and 0.9. On the public dataset, the refined RF model demonstrated exceptional predictive performance, highlighting the promise of a methodical machine learning approach to improve heart disease prediction. The external clinical validation and optimization of various patient populations should be the main areas of attention for future research.

Published: January 2024

The Ajali sandstone is a possible reservoir rock in the Lower Benue Trough (LBT)/Anambra Basin (AB), and understanding its geological, sedimentological distribution is essential for accurate prediction of fluid flow dynamic. Geological, granulometric analysis and laboratory hydraulic conductivity test are integrated for this investigation. Results from geological studies reveals three sandstone lithofacies; namely; AJALI L2A a sandstone intermixed with siltstone, lamination, bioturbated, and crossed bedded, AJALI L2B sandstone mixed  with silty clay, crossed bedded and bioturbated and AJALI L2C an excessive weathered sandstone with visible ripple and ridges with all sedimentary features supporting the earlier proposed fluvio-deltaic depositional environments. The granulometric analysis reveals medium to coarse grain, poorly sorted sandstone lithofacies. Hydraulic conductivity test for AJALI L2A crossed bedded and lamination sandstone contributes smaller pore spaces between grains, which reduce overall interconnectivity of the pore network primarily decreasing the fluid hydraulic flow conductivity and thus lowers the permeability value to 75mD. While in the AJALI L2B intermixed with siltstone and clay sandstone, lowers porosity; but cross-bedding may have contributed positively to increase in permeability value to 1850 mD in this lithofacies. The weathered AJALI L2C sandstone with visible ripples and ridges significantly affect the physical properties and pore spaces obliteration by iron oxide, by contributing to reduction in the permeability value to 60 mD. In overall it is concluded that the Ajali sandstones generally will exhibits an average moderate permeability of 662 mD.
SPATIAL AND TEMPORAL DISTRIBUTION OF PORE THROATS IN RESERVOIR SANDSTONE: IMPLICATION TO PERMEABILITY VARIATION IN WEST BARAM DELTA, MALAYSIA
Authors: Yusuf Ishaq
Published: January 2024

This paper attempts to quantify pore throats distribution towards more effective approach to permeability prediction. The mercury inoculation capillary pressure (MICP) is used to calculate pore throat diameters, and porosity-permeability system (POROPERM) validates effect of pore throats diameters on permeability variations from core plugs. Results reveal three major classes of pore throats diameters (micropore, mesopore and macropore) from five identified pore throat types. It indicates also that the abundance of mesopore and macropore throats above 30% in upper section (1475 m – 1480 m) of Siwa well increases permeability above 990 mD, an increase in micropore throats in middle unit (2106 m – 2114 m) of BK-102 well vary permeability from 495 mD to 600 mD. Whereas, in the TK well, permeability is moderate lower between 230 mD to 670 mD due to abundance of macropore throats in groundmass of the fine to very fine-grained sandstones. In WL well, at depth from 1720 m to 1850 m, permeability is moderate higher varying between 120 mD to 945 mD attributed to abundance mesopore and macropore throats presence in coarse friable and medium grained sandstones within stratigraphic succession. The results also indicates that increase in percentage composition of mesopore and macropore throats above 20% holds potential increase in permeability, and conversely increase in micropore throats type 1-3 disrupts or lowers permeability. The understanding of spatial and temporal distribution of pore throats in wells, could improve accurate prediction permeability and hydraulic flow units in reservoirs
Optimization of Breakpoint Chlorination Technologies for Drinking Water Treatment: a Hungarian Case Study
Authors: Laky Dóra , Neguez Souha
Published: January 2024

Ammonium ion is one of the major pollutants found in drinking water sources in Hungary, especially in deep aquifers. under oxidative conditions, ammonium can transform into nitrite ions in the water system, posing potential health risks. In Hungary mostly biological process or breakpoint chlorination are used to eliminate ammonium ion from raw water during the drinking water treatment process. When breakpoint chlorination is applied, harmful by-products are formed. Trihalomethanes concentrations have long been regulated in Hungary, therefore during the design and optimization of the breakpoint technologies trihalomethane concentrations have been considered. However, haloacetic acids (HAA5) and chlorate ion have been recently regulated in accordance with EU Directive 2020/2184. Chlorate is a by-product that appears in treated water when sodium hypochlorite is used in breakpoint chlorination.Experiments were carried out at four Hungarian case study areas to determine the optimal strategy for breakpoint chlorination: applying higher chlorine dosages with lower contact times, or lower chlorine dosages with higher contact times. The investigations concluded that the preferable dosing strategy is to use lower chlorine concentrations and longer contact times. This approach reduces chemical demand (cost-effective) and has a neutral effect on THMs formation. it can be concluded that when the raw water contains ammonium ion concentrations above 0.5 mg/l, the use of sodium hypochlorite may raise concerns due to elevated chlorate ion levels in the treated water, particularly during summer. Further research is required to expand the optimization strategy, considering not only ammonium and trihalomethane concentrations but also chlorate concentrations.

Authors: Poornamazian Ali , Izadinia Mohsen
Published: January 2024

In this paper, iron slag is used as partial coarse aggregate substitution in Self-compacting concrete (SCC). The SCC samples tests were conducted after 28 days of water curing for samples with 0%, 10%, 20%, 30%, 40%, 50%, and 60% iron slag as coarse aggregate substitutes. This paper evaluates slump flow, V-funnel, L-box, compressive strength, flexural strength, splitting tensile strength, surface water absorption, capillary water absorption, electrical resistance, acid resistance, and ultrasonic pulse velocity (UPV) of concrete samples. Furthermore, scanning electron microscopy (SEM) of samples was investigated for evaluating cement paste microstructure. Samples containing 20%, 60%, and 60% iron slag as coarse aggregate substitute have higher compressive, flexural, and splitting tensile strength than control samples (about 18.4%, 28.6%, and 16.9% higher, respectively). In addition, using 10%, 20%, 30%, and 40% iron slag as coarse aggregate increased the compressive strength. Moreover, incorporating iron slag as a coarse aggregate decreased the mass loss of samples which were exposed to the acid environment compared to control specimens. Using iron slag as partial coarse aggregate substitution reduced the porosity of the cement matrix compared to control samples (based on SEM images).

Hypertension stands as a perilous non-communicable disease, often leading to emotional instability among affected individuals. Symptoms like irritability, sleeplessness, and stress are commonly experienced by those with hypertension. Sleep quality is notably disrupted, with patients frequently experiencing discomfort and worry, often manifested as headaches, leading to disturbed sleep patterns. A multi-pronged approach is crucial for optimal results. Non-pharmacological interventions, combining health education with stress management techniques like progressive muscle relaxation (PMR) and deep breathing exercises, prove beneficial. This study aimed to evaluate the effectiveness of this combined approach on the sleep quality of hypertensive patients, utilizing a quantitative pre-experimental one-group pretest-posttest research design. The non-probability sampling technique employed accidental sampling, involving 17 hypertensive patients meeting specific criteria. The Wilcoxon Signed Ranks test yielded a significant result (p-value) of 0.000 ≤ 0.05. The combined intervention of health education, deep breath relaxation, and progressive muscle relaxation exhibited a positive impact on improving sleep quality among hypertensive patients. Further qualitative research is warranted to explore the experiences of hypertensive patients engaging in routine deep breath relaxation and progressive muscle relaxation therapies.

Pantai adalah tempat yang nyaman buat berwisata dan jalan santai. Oleh sebab itu kebersihan daerah tepian pantai harus tetap terjaga demi kenyamanan bersama. Akibat ketidak disiplinan pengunjung, banyak sampah berserakat dan menumpuk tidak pada tempatnya setiap hari. Sehingga  petugas kebersihan kesulitan untuk membersihkan sampah secara manual. Oleh sebab itu diperlukan tahap awal merancang, kemudian dilanjutkan dengan pembuatan sebuah mesin pembersih pantai semi otomatis atau Beach Cleaning Machine untuk mengatasi masalah tersebut. Nantinya membersihkan pantai dengan menggunakan mesin ini dapat mempercepat proses pembersihan serta meringankan pekerjaan petugas kebersihan pantai. Prinsip kerja mesin ini menggunakan motor bensin sebagai sumber penggerak. Sehingga saat motor dinyalakan, maka mesin akan bekerja secara otomatis. Kemudian untuk mengarahkan gerakan mesin diperlukan seorang operator. Sehingga sangat tepat sekali menggunakan Beach Cleaning Machine untuk membersihkan pantai bila dibandingkan dengan memungut langsung ataupun menggunakan alat manual, karena dapat menghemat waktu pekerjaan.

Rancang bangun ini dilatar belakangi hasil observasi, studi literatur dan pengembangan mesin pelet terdahulu. Observasi mendapatkan hasil bahwa mesin pelet horizontal kurang efisien dalam segi waktu, karena pada mesin pelet horizontal membutuhkan komposisi bahan yang basah, bahan yang basah akan menghasilkan pelet yang basah pula sehingga masih membutuhkan penjemuran yang cukup lama agar pelet tersebut kering dan siap dikemas, hasil produk mesin pelet horizontalpun dalam segi bentuk kurang rata. Untuk meminimalisir masalah tersebut kami membuat mesin pelet vertikal, untuk mengefesiensikan tenaga kami menamabahkan mini conveyor sehingga operator tidak lagi mengeluarkan banyak tenaga. Mesin pelet vertikal ini di lengkapi motor listrik bertenaga 1 HP atau 746 watt, gear box 1 : 60, coveyor dengan tinggi 165 cm, piringan cetakan 3 mm - 10 mm, hoper diameter 60 cm dan roller diameter 3 cm - 10 cm. Sehingga dapat menghasilkan pelet 120 kg / jam.
