The present maniscrupt aimed to improve the castable refractory castable concretes. Thus, kaolin-based refractory castables investigated were carefully prepared. They are composed of 90 wt. % well-graded (coarse, medium, and fine) kaolin aggregate, 10 wt. % binding matrix and adequate amount of distilled water. The binder mixture was calcium aluminate cement (CAC) containing 80 % Alumina and magnesium-aluminate spinel (MA- spinel) or mullite either preformed or insitu. The castable batches were cast into cubes (25 x 25 x 25 mm), cured for 7 days under water, and followed by drying at 110ºC for 24 hrs. The samples were then subjected to firing at 1550°C for a soaking time of 1 hr. The phase composition of the prepared castable samples were investigated by using X-Ray diffraction (XRD) analysis, scanning electron microscopy (SEM), energy dispersive X-ray (EDX) analysis, differential thermal analysis (DTA) and thermal gravimetric analysis (TGA). Results of these investigations confirm each other.

In this research, phytochemical screening and antibacterial properties of Phyllanthus muellerianus were investigated to confirm the potency of the plant on the basis of ethno medicinal significance. The percentage yield of crude methanolic leave extract of Phyllanthus muellerianus was 12.58% while the phytochemical screening of crude methanolic leave extract of Phyllanthus muellerianus revealed the presence of anthraquinone, carbohydrates, tannins, alkaloids, flavonoids, cardiac glycosides, saponin and lipids. The result of the antibacterial activities showed that the crude methanolic leave extract of the plant exhibits high potency against all the tested organisms. These properties above may be the reason Phyllanthus muellerianus plant has been reported to be useful in the treatment of several ailments.

The purpose of the study was to determine the Principals’ mentorship programmes in secondary schools in Nandi County. The study used social learning theory by Albert Bandura. Descriptive survey design was adopted. The study sample consisted of 118 public and private 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 and charts. The study established that Mentorship builds confidence, established that on academic excellence, it reduces theft of student’s items, reduced prevalence of strikes and prevalence of failing to do duties. On the ethical living it reduced strikes but not much with theft and attendant to duties. The study finds mentorship the key and the most useful in terms of upholding discipline in the schools. Students mentorship programmes in schools in the county be mandatory. Study established that it enhances respect for diversity amongst students and teachers, improves academic excellence, improves career choices, ethical considerations, self-awareness, improves on leadership traits, learning on etiquette, assertiveness and diversity. The principals should make a regular practice and introduce mentorship programmes since if this was in the study it’s an indicator the discipline turn round will be within reach.

Majority of the females in Ethiope East has undergone Female circumcision either while as teenage or at the point of getting married orduring conception. Female circumcision is a practice that needs to be discouraged. This would only be possible through public enlightenment campaigns and sensetisation programs to mother and school students alike. The study focused mainly on the causes of Female Circumcision in the area and the consequences of the practice to the victim and the society at large. The rate of this practice was equally looked at and recommendations were also advanced towards discouraging of this practice. In order to achieve this task, a field survey was carried out with various methods. The use of questionnaires, oral interview, direct observation, and archival methods were used in gathering the data. For convenient purpose, six communities were selected in Ethiope East. The communities are Orhoakpor, Kokori Inland, Okpara Inland, Ovu, Eku and Abraka Inland. The data gathered from the field were presented in tables. The Pearson’s Product Moment Correlation Co-efficient was used for the testing and validity of the data to determine the degree of relationship between the data.

Pulmonary sequestration is a rare congenital malformation that receives its blood supply from a systemic artery. We report a case of pulmonary sequestration initially diagnosed as a hydatid cyst of the lung, surgical findings revealed an abscessed collection related to a pulmonary sequestration of the left lower lobe. Pulmonary sequestration remains a diagnostic and therapeutic challenge.

A Primary cutaneous leiomyosarcoma located in the left thigh is reported in a 83-year-old patient. The clinical examination found a voluminous ulcero-budding infected tumor, measuring 15 cm long axis. The result of the histological examination and the immuno-histochemical profile revealed the diagnosis of a leiomyosarcoma. The patient underwent extensive excision with cutaneous margins of three to five cm and carried the Gracilis muscle deep down. After one year of control we did not notice local recurrence. The prognosis remains poor. We recommend long-term follow-up of patients to prevent recurrence. The purpose of this work is to show the difficulties to make the diagnosis and describe our management of this rare case.

In the recreation and reusing of old clothing in different ways we are using our imagination, so it is essentially a celebration of expressing ourselves. It can be a challenge to make old clothing look good. Old pieces of clothing and who might want a chance to bring them back to life. Garments become fashion waste when they no longer fit, cease to appeal visually and ideologically, or are superseded by a superior version. This research aim sees available garment materials as a kind of fabric semi-finished product. It combines with the characters of clothing style and utilizes new design thought and craft to further change available fabric appearance style. Recreating fifteen garments designs waste to give them second life by repurposed, re-construction, re-cut and adding decorative elements (embroidery, stitching, threads, crochet techniques, and discharge printing) to change original appearance for a new fashion trend.

Despite the use of appropriate teaching and learning approaches and the government of investing resources to promote quality education, there is a continuous record of poor academic performance among students in National Examinations in Kenya. There was therefore need for a study to be conducted to establish the factors that affect their performance.The purpose of this study was to determine the relationship between Self Esteem and student academic performance. The study was anchored on The Marsh/Shavelson model self-concept. The study employed Ex-post facto research design. The study targeted students from public secondary schools in Nyeri County. Krejcie and Morgan (1970) formula was used to calculate the sample size of the students while Purposive sampling was used to select 25 teacher counselors making a total of 409 respondents. Data was collected using questionnaires, interview schedules and document analysis. The quantitative data from the questionnaire was first be subjected to preliminary processing through validation, coding and tabulation in readiness for analysis with the help of the statistical package for social science (SPSS) to analyze data. Descriptive statistics was presented using frequencies and percentages. Pearson Correlation Coefficient was employed to determine relationship that exists between the independent (Self-esteem) variables and dependent variable (student academic performance). In addition, regression analysis was employed to test the relationships in the study. Qualitative data was transcribed, thematically classified and arranged before they are reported in narrations and quotations according to research objectives. Major findings from the study indicated that there was a significant positive correlation between Self-esteem and student academic performance (r = .800; p = .000) showing a strong correlation between Self-esteem and student academic performance. This study therefore, recommended that there is need for the teachers and education stakeholders in the ministry of education and beyond should give great attention to student self-concept as it affects student academic performance in schools and that schools should promote self-advocacy skills. Strong advocacy skills lead to greater self-confidence. It is also important to for the teachers to understand student background. Schools should design effective feedback mechanism to encourage students to compare present performance against a goal and also against previous performance.

In the present work, the building waste material Red Kotta was treated with sulphuric acid and formaldehyde and used as an adsorbent for the removal of Methylene red from aqueous solution. The adsorption characteristics of Methylene red dye on untreated and treated Red Kotta powder was evaluated as a function of pH, adsorbent dose, initial concentration of adsorbate, contact time and temperature. The effective adsorption was found to be in pH range 2 to7, adsorbent dose 1gm to 5 gm, initial concentration (100ppm to 500ppm) and temperature range (283K to 313K). The results show that Red Kotta powder holds a great potential in removal of Methylene red dye from industrial wastewater.
