The effect of different concentrations of indole butyric acid (IBA) at 4g/L and 0.12/31.2 ml hardwood and semi hardwood cuttings of coratina olive was observed. Cuttings were taken in the month of February from coratina plant and dipped for 10 seconds in the required IBA solutions. The highest survival percentage, shoot formation, number of roots formation was maximum in 4g/L treated hardwood cuttings. The maximum numbers of branches were observed in hardwood cuttings as compared to softwood cuttings. It was concluded that either type of olive cutting treated with IBA solution 4g/L showed best results to propagate coratina olive.

The global poultry industry has experienced significant changes in the methods used to harvest and process the fresh egg over the past century. Applications of animal genetics and breeding have significantly increased in line speed for poultry operation. In this study aims at reviewing production factors that influence egg quality traits across the globe. The production factors so far utilized were classified into three main categories and presented based on their influencing capacity. For this purpose, two types of search criteria to find publications relevant to the scope of this review were employed. The first type was an automatic search performed on the following publishers' databases: ScienceDirect, Google's scholar, researcher gates, academia. The second type was a manual search on conferences, recent theses and dissertation that have not been published in journals from numerous Babcock University. Generally, 23 publications were reported for the breed; 17 for housing, and 19 for age of the breed after excluding studies that do not focus explicitly on breed, housing and age of the bird as production factors that influenced egg quality traits out of 183 potential relevant articles identified from January 2001 to December 2016. Thus, this review would provide animal genetics and breeding researchers in terms of identifying the most potent breed, adequate housing system and precise age for optimum production of birds with high quality.

In this paper, we introduce a new family of continuous distributions based on [0, 1]] truncated Frechet distribution. [0, 1]] Truncated Frechet Gamma ([0, 1]] TFG) and truncated Frechet inverted Gamma ([0, 1]] TFIG) distributions are discussed as special cases. The cumulative distribution function, the rth moment, the mean, the variance, the skewness, the kurtosis, the mode, the median, the characteristic function, the reliability function and the hazard rate function are obtained for the distributions under consideration. It is well known that an item fails when a stress to which it is subjected exceeds the corresponding strength. In this sense, strength can be viewed as "resistance to failure." Good design practice is such that the strength is always greater than the expected stress. The safety factor can be defined in terms of strength and stress as strength/stress. So, the [0, 1]] TFG strength-stress and the [0, 1]] TFIG strength-stress models with different parameters will be derived here. The Shannon entropy and Relative entropy will be derived also.

Malaria remains a major health problem in Nigeria. It accounts for over 60% outpatient visit and 30% hospital admission in Nigeria. Ineffective treatment of malaria is also one of the factors responsible for its prevalence. The prevalence of malaria and treatment procurement was studied in Ekiti state, Nigeria. The study was carried out using well-structured questionnaire comprising of three sections A to C, Socio-economic, input and output data; data on method, cost of treatment of malaria and expenditure were obtained. Multistage random sampling technique was adopted. The result obtained showed that males with percentage prevalence of 53% were more infected than females with 47%. Respondent with symptoms of fever and chills was 48.2% while 51.8% complained of headache and pains. 80.3%% of the respondents have knowledge of malaria transmission while 19.7% have no idea. 46.7% of respondents spent less than 1000 naira for treatment procurement while 53.3% spent more than 1000naira. However, there was a significant difference (p<0.05) between males and female's susceptibility to malaria disease. Therefore, as at the time of study, there is prevalence of malaria in the communities despite the knowledge of the respondents on transmission of malaria and treatment procured.

Impact of wrong sexual behavior of adolescent has been surveyed. It effect on the victims has been proven negative, with consequences like health effect including financial effect been a drawback, acting like a barrier to the ideal development of an individual adolescent. Wrong sexual behavior has been found to be on the increase, forcing adolescents to drop-out of school, exhibiting behaviors that do not conform to the development of the society. Result of this research findings shows the impact of wrong sexual behavior to include: Disregard for cultural/societal moral values, teenage/adolescent pregnancies, rapid increase in STDs and HIV/AIDS transmission, eagerness to practices illicit sexual acts, wrong conception about the opposite sex including sexual intercourse addiction with prostitution tendencies. The high positive percentages achieved from statistical analysis (respondent view-point) presents these impact as been on the increase, capable of dragging the society towards ruin. Recommendations of this study presents a view that the problem of adolescent wrong sexual behavior can be control , presenting guides like proper guidance and counseling , proper monitoring, aggressive sex education, reawakening of traditional African moral and value teachings, inclusion of sex education in religious teachings including proper dressing and restricting of adolescents from pornographic materials.
