A Randomized Controlled Trial to Study the Effects of Suboccipital Muscle Release Technique versus Neck Isometrics for Tension Headache in Medical Students
Full text linkBackground: Headaches are a prevalent concern among medical students, often attributed to stress, long study hours, and poor posture. Evidence is present to support the influence of sub-occipital muscle release technique and neck isometrics on reduction in tension type headache intensity among medical students. Objective: To compare and determine the effects of sub-occipital muscle release and neck isometrics in reducing headache intensity among medical students. Data Collection Procedure: A total of 40 participants with tension type headache were selected according to the inclusion criteria. Participants were divided into two groups, i.e. Group A and Group B, with 20 participants in each group. Sample size was calculated using Open Epi calculator. Non-probability convenient sampling was used for recruitment and then subjects were randomly allocated to both groups by sealed envelope method. Sub-occipital muscle release technique was performed in Group A. Group B was instructed to perform neck isometrics. These interventions were performed over a period of 4 weeks. Measurements were taken at baseline and 4 weeks after treatment. NPRS and HDI scales were used to assess the headache intensity. The overall duration of study was 6 months. Independent Sample T-test was used for between group analysis and Paired Sample T-test was used for within group analysis. Results: Between group analysis showed no significant difference in effects of Sub- occipital Muscle Release and Neck Isometrics with P-value > 0.05. Within group analysis demonstrated that both techniques were effective in reducing the headache intensity among medical students with P-value <0.05 in both groups. Conclusions: The results concluded that while both interventions demonstrated efficacy within their respective groups, there is not sufficient evidence to conclude that one intervention is significantly superior to the other

Mekong Delta a amount of alluvium sediments flows from upstream China to Vietnam by the river branches, then get out the Sea.This sediments accumulated gradually elevation the new land. The coastal where mangrove forests with a rich ecosystem of plants and animals. Over time, these forests change, with different plant species succeeding each other. This aims of this study to finding plant species, classification of forest types based on ecological regions, assessement the biodiversity of tree species, and compare the abundance communities, measuring the growth of the forest in these regions. In 2023, a comprehensive survey was conducted by using a systematic approach. Research content and methods. The content is to investigate the situation of woody plant species in mangrove forests in sub-regions with different ecological characteristics. The number of survey plots have done depend on the density of the forest, Base on the width of the forest range, the number of survey plots in sub region set up from 10 to 15 plots. In total, 68 plots have done established in the erea, the area of plot is 100 square meters (10m x 10m). Using the statistical software in forestry to survey and analysis data. The results of research is to find the number of species in each ecological region and growth situation, in which the important thing is to evaluate the adaptation of species in each sub-region to propose wich species to choose as the main species in aforestation the fastest land on sea. The result provided a complete picture of the tree species composition, distribution, and community structure characteristics in each ecological sub-region. The result of survey showed in the sub-region one is seven species. In the sub region two is eleven species. In the sub region three is eight species. In the region four is ten species. The total species of the mangrove forest in the Western Mekong Delta have 16 species from 11 plant families have been identified. Among these species have 6 dominant species include Avicennia oficinali),Avicennia alba, Rhizophora apiculata, Excoecaria agallocha, Someratia caseolaris, and Bruguiera yipamoriza. From the investigation have been found two species grow on the best on new land were Avicennia officinalis and Avicennia alba this findings show they can develope on the original new land for the shore of the Western Mekong Delta. The survey results also calculated the average of the height, diameter (D1.3), canopy, health of the nature mangrove tree for each sub region and total region. From these results showed the division of foresty structure, the structure of height, diameter (D1.3), canopy, heathy of the sub region and total region in the Western Mekong Delta. Suggestions after discovering during the investigation that there are Avicennia officinalis and Avicennia alba are two species that can implement development plants to expand natural land by planting on suitable sea surface areas for Mekong Delta of Vietnam. In addition, referring to research documents on these adapted species can exploit food and medicinal herbs in discovering the level biodiversity distribution abundance of these species.

Findings highlight that Kalanguya rituals such as the kalang and padit foster community unity, while the ba-liw and dayomti provide moral guidance and cultural education. The research reveals that modernization has altered traditional practices, often diminishing their prevalence. The study concludes that integrating Kalanguya cultural elements into educational curricula can enhance cultural appreciation and support indigenous knowledge preservation. Recommendations include developing indigenized instructional materials and exploring additional aspects of Kalanguya culture, such as migration history and festivals, for a more comprehensive understanding
Study of Heat Transfer in a Fixed Bed Centimeter Furnace with Pottery Walls : The Case of Natural Laterite and Kaolinic Laterite
Full text linkThe valorization of municipal waste is a good option for energy production. Our work consists of a numerical study of the heat equations in a fixed-bed centimetric grate furnace modeled by a natural laterite inner wall and a kaolin laterite wall. Simulation results showed that the kiln filling rate at 100% is 5 kg of fuel. From 500o C as the starting point for heating, the temperature reaches a maximum of 1225o C and 1050o C respectively for natural and kaolin laterite at 30 minutes of operation. In addition, the internal temperature is optimal around 35 ± 5 hgs-1 of internal air flow. A drop in internal temperature was observed after 35 minutes due to mass degradation and convection of the outlet gas. Natural laterite tends to retain heat inside the kiln more than kaolinite, which dissipates too quickly. These results show that, depending on how heat is converted into energy, the right materials and operations need to be chosen to optimize the process

A Method to Classify Users on Social Networks Based on Similarity Mesuring
No full textWith the express growth of social networks, users have joined more and more of these networks and live their lives virtually. Consequently, they create huge amounts of data on these social networks: their profile, interests, and behaviors such as posting, commenting, liking, joining groups or communities, etc. One of the basic issues in these challenges is the problem of estimating the similarity among users on these social networks based on their profile, interests, and behavior. This paper presents a model for estimating the similarity between users based ontheir behavior on social networks. The considered behaviors are activities including posting or sharing entries, liking these entries, commenting and liking the comments in these entries, and joining a group in the social networks. The model is then evaluated with a dataset collected from Facebook users. The results show that the model correctly estimates the similarity among users in the majority of cases
Modelling and Optimization of Reliability Functions for a Gas Compressing System
Full text linkThis study entails the optimization of a gas compressing system to maximize its reliability and subsequently cut maintenance costs. In the course of the work, an improvement of Mean Time To Failure (MTTF technique was achieved by varying different failure cost of maintenance with targeted system reliability for a gas processing system and this was done using LINGO application programming bundles which was used to run a Nonlinear Mixed Integer Programing Model (NLMIP) to effectively enhance the processing plant and the reliability of five individual systems, including air compressing system: impeller, bearings, mechanical seals, valves and cooling fan within the gas compression system. The Excel solver was utilized to process the mean time to failure (MTTF) and the evaluated MTTF was additionally used to assess and understand the system failure history. From the study outcomes, it was ascertained that the MTTF of a system can be controlled through a maintenance planned support program The study outcomes also helped to determine that an alternative way to deal with the conventional maintenance practice is developing a support program through the execution of system reliability that reviews the system framework and sub-component and key parameter index, such as repair rate and failure rate
