Styrene-divinylbenzene copolymer is a special macroporous strong base anion resin crosslinked with divinylbenzene that is specially selective for hydrophobic anions. It shows good mechanical strength and an excellent resistance to osmotic and thermal shock. The amination reactions were done by chloro dimethyl ether solvent at 45°C. TGA and FTIR techniques were used to investigate the thermo gravimetric analysis and structures of obtained resins, respectively. The exchange capacities of anion exchange resins (X-16) are 312 meq/100g as determined by titration method. Then the structure of PS-DVB resin was investigated by scanning electron microscope (SEM) technique. The SEM images showed that the porous structure of PS-DVB resin was approximately intact after amination reaction.

Studies have shown that alcohol use is a vice that has serious effects on the users. However use of the substance has been found to be highly prevalent among various populations including University students. In order to ascertain this assertion, this study examined the prevalence of alcohol use among the students of Mount Kenya University, Kenya. Data was collected from a population of 258 participants from Mount Kenya University who were between 18-26 years of age. The sample of the study comprised of 126 undergraduate students from the said university. This sample was selected using stratified purposeful sampling method. The instrument that was used for screening alcohol use among the students was the Alcohol Use Disorder Identification Test (AUDIT). Participants who scored 7 or less in AUDIT were considered to have low risk to AUD, hence they were casual and social drinkers whereas, those who scored 8 and above were diagnosed to exhibit alcohol use disorder. The distribution of participants’ gender scores showed that male participants who had AUD were higher at 10.9% as opposed female participants who had AUD at 5.5%. The frequency of participants who scored 7 or less were higher (215, 83.7%) compared to those who scored 8 or above on AUDIT (42, 16.3%). Therefore, the prevalence of alcohol use disorder among the students of Mount Kenya University was 16.3%. Recommendations were made for stakeholders to arrange for strategic therapeutic activities for different groups of students and especially those that are almost graduating from University.

A graph G=(V,E) with n vertices is said to be admitted prime labeling if its vertices can be labeled with distinct positive integers not exceeding n such that the label of each pair of adjacent vertices are relatively prime. Some previous work on prime labeling includes prime labeling of bipartite graphs and ladder graphs. In this work, a new graph called Snow graph which is a union of wheel and star graphs is introduced. A theorem is given to obtain a prime labeling for this graph and an algorithm for prime labeling is given.

The authors report one case of anorectal malignant melanoma, seen and managed in EFD-HGE Unit, Ibn Sina Hopital . It’s a very uncommun affection of bad pronostic. At the present time, the surgical management is the only therapeutical attitude.

Leadership plays a crucial role in the management of international airlines' alliance ground staff operations environment. Leadership that is transformational and proactive can serve to optimize the talents of a diverse and inclusive workforce and have the potential to affect an organization positively. This qualitative study was reinforced with the lens of the transformational leadership theory, as the purpose of this single case study was to explore the role of leadership in a U.S.-based international airline alliance, and their approach to leading ground staff operations, successfully. Managing a diverse workforce is often a challenge, as the aim is to ensure desired and optimal organizational effectiveness and performance, on which organizational sustainability and profitability hinges. The study entailed the collection of data using semistructured interviews in computer-mediated conferencing format with five airline alliance leaders located in the state of Georgia, who held at least 2 years of successful experience in leading a diverse workforce. The analysis using a process of constant comparison and thematic analysis yielded the principal theme of the importance of the proactiveness of leadership, in leveraging a diverse workforce, under the aegis of strategic human resources management, and leadership. A key recommendation is for airline alliance leaders to display astute transformational skills and align diversity, equity, and inclusion policies as a critical corporate human resources strategy. Optimizing employee performance is vital in gaining a competitive advantage in a field where service quality is a key differentiating factor in being superior among equals.

To contribute to the resolution of the problem relating to the growth of plantain (Musa spp.), the growth parameter of plantain was evaluated under Kindu conditions using the Fertilizers (Control, Sawdust and rice husks) as substrate. The experiment was conducted in the experimental device installed in the concession of the University of Kindu, department of phytotechnics comprising 6 treatments, corresponding to ten repetitions for each treatment. The observations made during this investigation focused mainly on the diameter at the collar (cm), Height of the pseudostem (m) and the leaf area).The results obtained showed that:The height of the pseudostem, the diameter at the collar and the leaf area varied from one cultivar to another and according to the fertilizers used; - Sawdust was the best fertilizer, compared to rice husks and controls; - the Mbonjilo C4 cultivar is the tallest cultivar, from the point of view of the collar diameter it is the Mbudi 1 cultivar, on the other hand from the leaf area point of view it is the Mbonjilo cultivar which has the most open leaves.

The proximate and anti-nutrient profiles of Dioscorea bulbifera tubers were determined. The proximate profile included high crude fiber (18.17±6.28%/wet weight and 20.34±6.67%/dry weight) and total carbohydrate (60.83±3.82%/wet weight and 68.41±5.78%/dry weight). The anti-nutrients composition included tannins, cyanogenic glycosides, oxalates, phytates and saponins. These results support the medicinal uses of Dioscorea bulbifera tubers, and suggest its potentials as food, after proper processing

Education is one of the strongest predictors of health. Early termination of education can negatively impact health, shorten life span, and increase stress on the healthcare system. Although improving overall high school graduation rates have been debated and discussed by the Toronto District School Board and the Ministry of Education, there is a paucity of research studies on increased graduation rates as they relate to public health in a Canadian context. The purpose of this phenomenological qualitative study was to explore the perceptions of liaison public health nurses, who worked directly with the Toronto District School Board, regarding influencing students in Toronto, Ontario to complete high school. Bronfenbrenner’s ecological model was the underlying conceptual framework for the study. Purposive sampling was used to select 10 public health nurses who were interviewed regarding their role and involvement in high schools. Data were subjected to triangulation and were analyzed to identify commonalities and trends and patterns. The findings from this study indicated that liaison public health nurses believe that high school dropout out is a public health issue and that collaboration between the Ministry of Education and Public Health is needed to address the issue. The emergent recommendations from the analysis of data indicate the potential for greater to explore the connection between health and school achievements and the expanded role of public health nurses in Canadian high schools. With increased research and resources, improving graduation rates students may be expected.

A well-functioning hospital information system must ensure the production, analysis, dissemination and use of reliable and timely information on health determinants, health system performance and health status. The aim of this study is to contribute to the improvement of information management and, by extension, to strengthen the overall performance of the Makélékélé Base Hospital. We conducted a descriptive cross-sectional study, at the Makélékélé Base Hospital in the first arrondissement of Brazzaville, the political capital of the Republic of Congo. The study took place during the period from 1 July 2020 to 8 February 2021. Authorisation to collect data for the study will be sought from the Hospital's General Management. In total, 55 questionnaires were completed by data management staff in the health information system field. More than 50% of the respondents answered that the same tools were used from year to year, site to site (58.18%) and that data collection was done according to the same methods from year to year, site to site (69.09%). Only 83.64% of the respondents answered that data from all reportable sites are included in the overall data, while 36.36% answered that there are measures in place to ensure data completeness. There were 69.09% of respondents confided the existence of the risk of the data being used for personal or political purposes. In our study, the analysis of the constraints of health information management was mainly related to data quality problems. The quality of health information is poor and does not allow the establishment of an efficient hospital system. The use of health information is insufficient to allow the implementation of an efficient hospital system. 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. The two investigations revealed that the "data quality" component had significant shortcomings that should be prioritised in the management of the Hospital Information System. Health information is essential for monitoring progress in improving and maintaining the health of populations and the functioning of the health system.

We report the case of a 69-year-old man with radiation-induced osteosarcoma of the mandi-ble diagnosed four years after radiation treatment for squamous cell carcinoma of the tongue. Although radiation therapy is a proven treatment modality for malignancies of the head and neck, it can have adverse effects. Late complications in bone following radiotherapy include osteoradionecrosis, radiation-induced osteitis, and osteosarcoma, which is an uncommun tumor, diagnosed by meeting certain diagnostic criteria. The mandible is a location very sensitive to radiation effects.
