The management of osteochondral tumors is a major challenge due to their rarity, diagnostic complexity, morbidity, and mortality. The objective was to assess the epidemiological, diagnostic, and therapeutic aspects of osteochondral tumors in Bamako (Mali). A retrospective, multicenter, descriptive, and analytical study was conducted over a five-year period (January 2019 to December 2023) in three university hospitals of Bamako, Mali. Patients admitted during the study period with complete medical records who were followed for at least six months were included. The prevalence was 6.2 cases per 10,000 patients. The mean age of patients was 35.3 ± 20 (range: 2 to 82 years). Pain was the most common presenting symptom in 90.6% (184 cases). Pelvic localization represented 166 cases (81.3%). There were 154 cases of malignant tumors, including 140 primary cases (70%) and 14 secondary cases (7%). Stage IV according to the TNM classification represented 26.1% of cases. Surgical treatment was the most common, accounting for 61.6% (125 cases), combined with chemotherapy in 106 cases (52.2%) and/or radiotherapy in 7 cases (3.4%). The outcome was favorable in 59.1% of cases. Recurrence and death were associated with malignant tumors in 16 cases (7.9%) and 19 cases (9.3%), respectively.

Today, consumers can go through different online channels by which they are able to interact with sellers. This research has specifically examined the factors essential for the acceptance of online shopping in Pakistan. These factors have been selected on the basis of international market literature that will provide ways to implement online shopping in Pakistan including the personal choices of the users. Four hypotheses were developed and tested with the help of a systematically designed questionnaire, comprising of over fifty questions. Where, H1: Muslims are more reluctant to adopt online shopping option as compared to consumers from Pakistani Christian community. H2: Females from urban background are more inclined to purchase online than the females from rural background. H3: Fear of insecure dealing of personal information is positively associated with refusing online shopping websites. H4: The choice of online shopping is more dependent on the quantity of information provided about the product with suitable illustrations on the website than the colour or font of the website content. The questionnaires were distributed among 500 students of the selected institutes throughout Islamabad, Pakistan at random. H1 and H4 were supported while H2 and H3 were not supported by the data. The findings of this research are helpful for the e-marketers and managers to better understand the methods of increasing the online sales via online retailing in Pakistan. The major limitation of this study is that it is focused on the students studying in the universities of the single geographical location, therefore the results may not be generalizable to other geographical locations.

Five derivatives of oxazolone were synthesized by using Erlenmeyer azlactone synthesis. Antibacterial and antifungal activity of these oxazolones was evaluated on selected skin microorganisms. Preliminary screening was performed to identify growth inhibition, and MIC (Minimum Inhibitory Concentration) was determined for the active compounds. Results obtained were very promising and the most active compound in our screen was the dimethoxy substituted oxazolone, which demonstrated a significant enhancement of antimicrobial activity both against selected bacterial and fungal strains. The MIC value of the highly active compound was found to be 12.5µg/ml.

The occupational radiation doses for medical staff at the Sheri Kashmir Institute of Medical Sciences (SKIMS) Hospital's departments of diagnostic radiology, nuclear medicine, radiotherapy, cardiology, gastroenterology, radiological physics, and bioengineering were monitored and evaluated. To ascertain the status of their average yearly effective dosage and average cumulative lifetime exposure, 250 medical radiation employees were observed. The Radiation Safety Lab of the Department of Radiological Physics and Bioengineering at SKIMS was where the analysis for this study was completed. Based on their clinical responsibilities and expertise, the observed personnel were divided into two subgroups: technical professionals and physicians. Thermo luminescent dosimeters (TLD-BARC (CaSo4:Dy)) were used to measure the whole body doses in all categories of workers, with the exception of those in the cardiology lab and gastroenterology, for whom the TLD was worn under the lead apron (0.5millimeter lead thickness). Additionally, an extremities dosimeter was given to each of the three departments—nuclear medicine, cardiology, and gastroenterology. Radiological physics, nuclear medicine, radiation, cardiology, gastroenterology, BE, and SKIMS Medical College employees' annual average effective doses were found to be 0.26, 0.60, 0.18, 0.35, 1.37, 0.17, and 0.25 mSv, respectively. The average hand/extremity dose recorded by the department of nuclear medicine utilising the unsealed radioisotopes was 1.06mSv. Cardiology and gastroenterology, two departments that use fluoroscopic guidance for a variety of procedures, were also given an extra extremity dosimeter, and the average dosages were discovered to be 0.42 and 5.57 mSv, respectively. The measured annual dosage resulted in levels that were significantly lower than the international recommended occupational dose limit.

At the Makelekele base hospital in Brazzaville, the most neglected aspect of activities is hospital information management. Our study aimed to assess the quality of information by interviewing patients hospitalised or consulting at the Makélékélé base hospital between July 2020 and February 2021. This was a descriptive cross-sectional study with a qualitative approach based on the quality criteria of the Delone and MacLean models. Our study population consisted of a group of patients, users of hospital information. The patients gave their consent to participate in the survey. Confidentiality and anonymity of the data were ensured. A total of 300 patients responded to the questionnaires, most of them with a satisfaction rate of over 60%. The satisfaction rate of the patients appeared to be satisfactory with regard to the comfort and cleanliness of the room (63.27%), the noise in the ward (60.20%) and the organisation of discharges. The responses (90-100%) regarding possible improvement of the quality of the data were maximum. The statistical results were significant. Our survey revealed a relatively positive patient satisfaction rate regarding the quality of care, the comfort and cleanliness of the room and the noise in the ward. Patients were satisfied with the organisation of hospital discharges. Most respondents were unanimous about the evolution of data quality. The measurement instrument used for this exploratory research concluded that the target population had a high level of satisfaction. Users were clearly satisfied with the current information system. This investigation revealed that there were significant gaps in data quality that should be prioritised in the management of the Hospital Information System. Our study has allowed us to understand the constraints that hinder information management in the hospital. There were specific elements of health information that need to be diligently applied (information quality) or improved and enhanced (information use).

The purpose of this article is to examine the broad contours of Eritrea-India relations in the past two decades, and in turn to stimulate further academic and policy researches with specific focus on the opportunities and challenges. To this end, secondary and primary sources have been thoroughly referred. Eritrea-India relation was formally established when Eritrea emerged as an independent sovereign state on May 24, 1993. Since then, both countries shared multi-dimensional relations, but with very limited results. India has provided manifold assistance to Eritrea in areas, such as agriculture, education, and science and Technology. India’s engagement with Eritrea also extended to technical assistance, training and capacity development under the framework of South–South cooperation. Recent development in trade and various investment initiatives are also a reflection of the new stride in the bilateral friendship. In addition, Eritrea has been hiring a great number of skilled labour from India. However, the bilateral relations is not always without estranges. Trade imbalance, restrictive monetary and fiscal policies and Eritrea’s more closeness to China are among other fault-lines. The balance sheet of the two states bilateral relations however proves the positive gains from the current diplomatic impetus. Finally, the researchers suggested to Eritrea and India to make more effort to bit back fences against the curve of evolving bilateral relation and avoid obsolete mechanism which is purely interest driven.

This paper deals with the performance analysis and optimization of working parameters of a flat plate solar cavity collector. Cavity type configuration is an improved version of a flat plate collector. It is evident that every solar gadget need a little bit of improvement in order to perform well. Various experiments both theoretical and experimental are going on in various countries to achieve better performance of flat plate collector. Hence the better choice for the improvement of flat plate collector is the cavity collector. Usually the cavity type configuration is utilized for focusing, solar tower and Fresnel lens collectors. But it was experimented for the flat plate improvement and hence it is proved to be a one of the alternate solution for the flat plate collector. It also works more efficiently even at low radiation source for a certain period of time and at part cloudy days. Solar Cavity Collector (SCC) has been experimented with various working parameters like change of receiver material (Copper and Aluminum), various L/D ratio, change of inclination angle, change of mode of flow (parallel and serpentine), collector packed with pebble bed and metal chips to enhance the heat transfer phenomena in the collector, by increasing the number of cavities and Collector with end plates. End plates were welded at entry and exit of the receiver pipes to stagnate the water for a while inside the collector.

The purpose of the study was to determine the extent induction of students into school culture influence students’ discipline in secondary schools in Nandi County, Kenya. The study used systems theory by Ludngvan Bartalanffy. Descriptive survey design was adopted. The study sample consisted of 118 public schools’ principals, 108 teacher and 1534 student leaders. Each school provided 13 student leaders. Questionnaires for principals, interview guide for teachers and student leaders were used as instruments of data collection. Data was analysed using SPSS. Descriptive statistics was used to analyse data then, tabulate and present data. The results generated were reported in tables. The study established that school culture defines the students, the school, the reputation, mannerisms and performance. Formal induction sets the rules, norms, expectations, behaviour patterns, the goals and objectives and the set school agendas. The study established that pairing of new students to older ones is not significantly related. It established that formal orientation, giving documents on school ethos, guest speakers who inculcate long lasting impressions on the students, introducing them to successful alumni of the school for inspiration give guiding principle to stay in the school. This impacts positively and the student discipline improves. The government should ascertain that Student leaders are inducted and due to its sensitivity the MOEST should devise a system of encouraging the formation of county bodies to specifically carry out induction of the chosen leaders in clusters of sub counties or the lower units. This will enhance the training and its impacts. The present scenario is national conference for a few students for three days and the sub county a day and this is grossly insufficient and will not make much impacts.

This paper aims to examine how the extra-curricular activities affect the social skills of students. Social skills to be implemented here is communication skills and students; self-confidence. Student participation in co-curricular activities helps to promote students’ social skills in order to enter any field for the future prospect to produce skilled human capital in terms of academics and character. Mastering social skills is vital as it gives a good impact in generating positive relationships of a particular student. Active student participation in extra-curricular activities outside the classroom environment allows the students to interact with teachers and friends and to some extent act as a catalyst for social skills development of a student. In addition, through extra-curricular activities, the production of excellent human capital from the physical, emotional, spiritual and intellectual aspect can be developed. Involvement in leisure activities also leads to the interaction of students with environment, social and learning inside or outside of the classroom in order to produce excellent human capital development. It will also encourage the development of talent, creativity and students potential to the maximum level. Therefore, the direction of this concept paper seeks to unravel the relationship between extra-curricular activities and their impact on social skills because it could act as a catalyst for the development of students social skills. Therefore, extra-curricular activities should be given the ‘right’ in Malaysia education system.

Many advance colorimetric analytical techniques or methods are available to estimate/determine environmental pollutants like selenium, vanadium, thallium, iodine, sulphur dioxide, pentachlorophenol, carbon tetrachloride, mercury. Many researchers opined to make use of automatic or continuous air monitoring station. Central Pollution Control Board established many CAAQMS in all over India, but for operation of these stations is generally required skilled persons as well as a huge amount is required to install CAAQMS. According to CPCB the installation of CAAQMS approximately 1.1 crore rupees and 8 lakh rupees for operation and maintenance annually was met. Low cost method for estimation of sulphur dioxide (SO2) is being used right now in manual monitoring stations in India. The study applies the feasibility of the alternative low cost method; Rhodamine-B has been used as a simple and sensitive colorimetric reagent for the estimation of sulphur dioxide. The results have significantly indicated that the use of NCS method for the alternative to TCM method could able to save around 3.54 crores rupees per year from proposed 1352 manual Air monitoring stations in India.
