The deflection of thin orthotropic rectangular plate under moving loads is a classic problem in solid mechanics. However, the equations are challenging to solve due to their non linearity and complexity. At the same time, this equation is a coupled fourth order partial differential equation having variables and singular coefficients. In this research article, the partial differential equation is converted to a set of coupled second order ordinary differential equations by using a special technique adopted by Shadnam et al., [19]. This transformed set of second order ordinary differential equations is then reduced using modified asymptotic method of Struble and Laplce transformation. The closed form solution is evaluated, resonance conditions are obtained and the results are showed in plotted curves to solve the variations in amplitudes for some varying orthotropic plate parameters with elastically supported ends under moving loads for both cases of moving distributed force and moving distributed mass.

This study is about committing anti-social activities like: theft, illicit sexual relations, use and trafficking of drugs, fighting, destruction of property and cheating (juvenile Delinquency) by high school students ages 14-18 in Kisii Central Sub-County, Getembe Zone, Kenya. The purpose of the study was to explain the extent to which suicidal ideation, help-seeking behaviour, and use of media influence JD among secondary school students in Kisii Central Sub-County, Getembe Zone. It was also about the extent of differences in JD according to family type and perceived social class. The objective dealt with in this paper was to investigate the relationship between help-seeking behaviour and Juvinile Delinquency among secondary school adolescents in Kisii county, Kenya. Kisii Central Sub-County was selected because no similar study has been done there and because acts of student violence are apparent there. Probability and non-probability sampling methods were used. Questionnaires were used to collect data from students and teachers, interview schedules for principals, and focus group discussion questions were used on parents. The results indicated that respondents who scored highly in help-seeking behaviour were more delinquent than those that had a low score. The conclusion was that young people who think that they do seek help probably seek it from irresponsible people. It was therefore recommended that youths should be sensitized to seek help from caring persons in order to reduce cases of juvenile delinquency.

This research article considers the flexural rigidity influence along both x and y axes on the dynamic response of orthotropic rectangular plate resting on constant elastic foundation with elastic end conditions. The orthotropic rectangular plate model is a coupled fourth order partial differential equation having variables and singular coefficients. The solutions to this model are arrived at by reconstructing the fourth order partial differential. This partial differential equation model is converted to a set of coupled second order ordinary differential equations by using a special technique adopted by Shadnam et al., [11]. This set of second order ordinary differential equations is then reduced using modified asymptotic method of Struble. The closed form solution is evaluated, resonance conditions are obtained and the results are showed in plotted curves to depict the influence of flexural rigidities along both x and y axes on the dynamic response of orthotropic rectangular plate resting on constant elastic foundation with elastic end conditions for both cases of moving distributed mass and moving distributed force.
The primary objective of this research is to study the Jordanian Cybercrime Law No. (17) of 2023 between regulating social media sites and restricting freedom of opinion. In addition, it clarifies the concept of cybercrimes and how to control social media sites while preserving citizens’ rights to freedom of expression. In terms of balancing digital security and controlling social media sites. Defining concepts and terms, such as “regulating” social media sites and “restricting freedom of opinion,” is crucial to understanding the law's impact on users. Monitoring and implementing the law by the competent authorities to avoid excessive violations of individuals’ rights. The researcher used the descriptive analytical method, as well as the inductive method, and the legal text analysis tool was used. This research has reached several results, the most important of which are that the Jordanian cybercrime law has used broad, vaguely defined, inaccurate, ambiguous, and non-specific terms, such as fake news. Even though these texts do not meet the requirements of international law regarding drafting legal texts precisely enough to allow individuals to regulate their behavior accordingly. In addition, the Jordanian cybercrime law focused on the penal and punitive dimensions and did not include any institutional or preventive measures to reduce negative phenomena in the digital environment. This research has reached several recommendations, the most important of which are that the Jordanian legislator must reconsider amending legal texts that are unfair to internet users in a way that leads to the adoption of balanced legal texts compatible with basic rights. These rights include the right to exchange information, the right to express opinions and ideas, and the right to privacy, which the Jordanian Constitution guarantees in Article (7).
Background: Viral conjunctivitis is a prevalent eye infection that is typically linked to epidemic circumstances. The aim of this study was to evaluate the clinical features of continuing viral conjunctivitis in Sudan during times of conflict. Methodology: This is a prospective descriptive study that was launched after seeing an uncommon presentation of acute hemorrhagic conjunctivitis in people of all ages around the beginning of August 2024. Results: Subconjunctival hemorrhage (SCH) was observed in a total of 83 cases, with 76% being males and 95% being females. Swelling of the eyelids was observed in 82 patients, with 82.5% being males and 81% being females. Conjunctival edema was observed in a total of 79 patients, with 77.7% being males and 81% being females. The majority of the patients exhibited symptoms in both eyes, while 8% and 4% experienced symptoms in the left eye and right eye, respectively. Conclusion: This pandemic of viral conjunctivitis, which often begins in one eye and spreads to the other, can clear itself in a week or two, based on the typical clinical symptoms. Steroids and antibiotics work synergistically to alleviate symptoms and avoid bacterial infections.
Curriculum based ideological and political education is a new requirement for talent cultivation in universities in the new era of education reform. It includes diversified curriculum based ideological and political education elements such as norms, culture, and competition in traditional ethnic sports, and is the main path to achieve the fundamental task of cultivating morality and talents. On the basis of exploring the effectiveness of traditional ethnic sports teaching in undergraduate colleges under the background of curriculum ideological and political education, this article analyzes how to carry out traditional ethnic sports teaching in undergraduate colleges under the background of curriculum ideological and political education, and give full play to the educational value of traditional ethnic sports.

Strategic administrative initiatives in schools helps in identifying emerging trends and anticipate future challenges, allowing them to prepare and respond proactively so as to bring change in students’ academic performance. For three consecutive years (2016 -2018), Kisii County’s mean standard score in Kenya Certificate of Secondary Education declined resulting to an average mean standard score of 3.765 (D+) which was still below the National Mean Standard Score of 3.962. The purpose of this study was to determine the extent to which strategic administrative initiatives influence academic performance. Education Production Function theory was applied. The study employed a descriptive survey design. Target population of 353 principals and 4354 teachers were considered from 353 public secondary schools in Kisii County. Slovin’s formula with a margin error of 0.05 was used to sample 28 principals and 341 teachers as respondents. Stratified random sampling was used to get school categories. Instruments for this research included: questionnaire for teachers and interview schedule for principals. Validity of research instruments was ascertained by supervisors’ inputs from the School of Education Kisii University. Questionnaires were considered reliable since Cronbach’s Coefficient Alpha 0.998 obtained was higher than the critical Cronbach alpha of 0.7 on a scale of -1 to +1 by use of test re-test method. Data was analysed both qualitatively and quantitatively. Qualitative data on interview schedules were organized based on research objective and themes of study. Data was presented using percentages, means, frequency distribution tables and bar graphs for easier interpretation. This study’s findings were: The strategic administrative initiatives have a positive influence on academic performance. This study is significant as it indicates that county and sub-county secondary schools need to improve on the application of the strategic administrative initiatives in the academic activities/programs for them to do better academically. In conclusion, National and Extra- County secondary schools’ strategic administrative initiatives have a high positive influence on academic performance compared to county and sub-county secondary schools.
