This study was conducted to investigate the factors that contribute towards the turnover intention of teachers of private sector schools of Sargodha division. For this purpose several factors of satisfaction i.e. security, nature of work, working condition, colleagues (integration), principal, students, recognition, social status and promotion are considered because these are the main factors which increase or decrease the turnover intention of teachers. Data was collected through paper and pencil technique from various private schools of Sargodha division. Pearson correlation and zero order correlation were used to test the hypotheses. Only four factors i.e. principal, promotion, pay and working conditions were proved to have a strong negative relationship with turnover intention.

Moringa oleifera (M. oleifera) is renowned for its range of essential nutrients and bioactive compounds. However, the toxicity and potential radiation modifying effects of extracts from its entities are not well characterised. The cytotoxic and radiomodulatory effects of aqueous extracts obtained from seeds, leaves and flowers of M. oleifera were evaluated. Cytotoxicity and radiation modifying effects of extracts were assessed in apparently normal Chinese hamster lung fibroblasts (V79 cells), using the colony forming assay. The free radical scavenging activity of each extract was also assessed, using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. At relatively low concentrations of 6.25–100 µg/ml, the seed extract showed about 20% cytotoxicity and yielded radiation sensitizing factors ranging from 1.23±0.07 to 2.38±0.76. The leaf extract was non-toxic at concentrations of up-to 50 µg/ml, but produced ~12% cell kill at 100 µg/ml. With the little or no cytotoxity on its own, the leaf extract was radiosensitizing, with radiation modifying factors ranging from 1.30±0.18 to 1.50±0.26. At all tested concentrations, the flower extract was non-toxic, but significantly enhanced cell growth in unirradiated cultures, showing no effect on cellular radiation response. With the exception of the leaf extract which had a maximum of only 9% free radical scavenging capacity, the other extracts showed no potential as radical scavengers. Aqueous extracts of seeds, leaves and flowers of M. oleifera may potentially be clinically useful as cytotoxic agents, radiosensitizers, and wound healing promoters.

Macabo (Xanthosoma sagittifolium (L.) Schott.) May be a solution to the problems of hunger, inadequacy and food insecurity faced by several developing countries like DR Congo, because it is adapted to tropical equatorial and tropical climates. However, its large-scale cultivation encounters a problem of lack of propagating material in quality and quantity sufficient for the extension of the culture related to its mode of multiplication and growth. Indeed, the pronounced dominance of the terminal bud inhibits the development of lateral buds. To try to solve this problem, a study was carried out by experimenting the PIF method in Kisangani. It consisted in evaluating the rejecting power of X. sagittifolium bulbs planted on three different substrates, notably sawdust, charcoal (bio-char) and rice husks. The parameters observed were respectively the recovery rates of the mother bulbs, the number of offspring formed and weaned. The results obtained showed that: 1. The recovery rate of mother bulbs was 100% irrespective of the treatment; 2. After 24 weaning, a 9.6 cm diameter bulb produced 32 and 34 3 cm diameter shoots respectively for sawdust and bio-char, and 32 x 2.9 cm diameter shoots with bulb 8.8 cm in diameter for rice balls. These numbers of offspring do not differ statistically; 3. There is a positive correlation between the size of mother bulbs and the number of offspring formed (Y = -32,057 + 6,926X with r = 0,521) and secondly between the size of mother bulbs and the vigor of the offspring formed (Y = 1,300 + 0,182X with r = 0,560). These results show that the number of offspring formed increases with the size of the mother bulbs and their vigor also depends on it.

The aim of this study is to detect Total Electron Content (TEC) anomalies before (Mw=7.0) Haiti earthquake on 12 Jan 2010. Three earthquake-associated TEC anomalies appear at 15:00, 20:00 and 22:00 on 11 Jan 2010 (UTC), 1 day before this earthquake. The analysis results are examined using a mathematical tool called Principal Component Analysis (PCA). After more detailed analysis using PCA, each of three TEC anomalies lasts about 30 minutes.

The paper explores the link between Islamic accounting and the cash Waqf. It exposes and introduces the reader to accounting for cash Waqf in medieval times and in contemporary times. It tracesdiachronically the legitimacy and use of cash Waqf, describes Islamic accounting and highlights its relevance for cash Waqf accounting. The paper concludes with an opinion on the application of the seemingly recent phenomenon of Islamic accounting with specific reference to cash Waqfs.

Isolated ischemia of the caecum is a rare condition, with only a few reported cases in the literature and most often manifested by pain in the right iliac fossa.The mode of revelation by occlusive syndrome is unique. With early medico-surgical management, the prognosis is relatively excellent.We report an original case of isolated ischemia of the caecum revealed by an occlusive syndrome.

The study sought to know how Library and Social Media serve as a facilitator for national unity and security in Nigeria. The study adopted a correlational research design with a population of 3,840 comprising of students and lecturers of different levels. A random sampling technique was adopted and Krejcie and Morgan method was used to determine the sample size of 350. The instrument used was tagged “Library and Social Media as a Facilitator for National Unity and Security (LSMFNUSQ)”. The instrument was validated by five experts and a field trial of test retest was done to know the internal consistency which yielded 0.79 co-efficient. 350 copies of questionnaire items were face-to-face administered to the respondents and 200 successfully retrieved. Mean statistics was used to analyse the research questions and Pearson Product Moment Correlation (r) was adopted to test the hypotheses. The study noted that Library and Social Media played a high level of role towards national unity and security. Among other things, the study recommended that there is need as an issue of priority to establish more public and school libraries which will help cultivate reading habits among youth and adults. Books on security issues should be stocked in the libraries for users
