Aim: The shear strength of wood is a very significant parameter required in describing the potential of woods in making wooden structure. This study is aimed at comparing the shear strength of Pentaclethra macrophylla and Erythrophleum suaveolens with respect to their fibre. This is to determine the suitability of including Erythrophleum suaveolens in making traditional motars in order to reduce the demand load on Pentaclethra macrophylla. Methods: The heartwood samples of Pentaclethra macrophylla and Erythrophleum suaveolens for maceration were fixed in specimen bottles containing formalin-acetic-alcohol (FAA) in the ratio 90:5:5 to prevent fungal growth. The preparations involved cutting small clear samples of the heartwood of the two timber species of fabaceae family. The shear strength parallel to the grain test was conducted using a Hounsfield Tensometer. Results: Significant differences were recorded across the fibre characteristics of the two plant species. The share strength of the 25 wood samples from the two plants each fluctuate around 100 to 200 N/mm2.  On the average, P. macrophylla recorded higher shear strength as compared to suaveolens however no significant difference was recorded between the means when tested for significant differences using independent sample t-test. Conclusion: Since the shear strength of E. suaveolens is comparable to that of P. macrophylla, it  is therefore recommended its substitute for the manufacturing of wood based products where P. macrophylla has been in continual usage in order to relieve the pressure and demand on P. macrophylla.

The spawning potentials of Heterotis niloticus from Great Kwa River and Cross River was compared in a twelve-month study. Forty-nine female H. niloticus was sampled from Cross River and thirty four from Great Kwa River from January to December 2014.  Gonadosomatic index (GSI), fecundity and histological examinations were investigated in the Institute of Oceanography laboratory. Each month of this study recorded at least one female specimen with eggs at different stages of development. In Cross River, the months of August and September recorded one hundred per cent female with eggs, while Great Kwa River exhibited such performance in July, an indication of spawning activities by the fish. Cross River had a major GSI peak in July with a minor one in August, but Great Kwa River did not exhibit any significant GSI peak throughout the study, and no significant difference in GSI between the rivers when compared with T-test (0.22; P>0.05). There was a significant difference (0.02, P<0.05) in fecundity of H. niloticus between the population in Cross River and Great Kwa River. Regression analysis of fecundity and body weight showed a positive correlation (P<0.05)(r=0.3686). Histological changes in the gonad of the fish showed no disparity between the rivers. H. niloticus has the ability to spawn all year round, but in the Cross River, the fish has high reproductive potentials than those in the Great Kwa River.

Radiographic Mandibular Indices serve as easy and relatively cheap tools for evaluating bone mineralization. Objectives: To examine the effect of age and gender on three mandibular indices: the panoramic mandibular index (PMI), the mandibular ratio (MR) and the mandibular cortical index (MCI), among Libyan population. Methods: The three indices were measured on 317 digital (OPGs) of adult humans (155 males, 162 females). The sample was divided into six age groups (from 18-25 years through 56-65 years). The measurements were analyzed for interactions with age and sex, using SPSS (Statistical Package for Social Studies) software version no. 22. The tests employed were two way ANOVA, the unpaired T-test and chi-square test. Results: The mean PMI fluctuated between 0.37 s.d. 0.012 and 0.38 s.d. 0.012. among the sixth age groups. One-way ANOVA statistical test revealed no significant of age on PMI. On the other hand gender variation has effect on PMI, since independent sample t-test disclosed that the difference between the male and female PMI means statistically significant. ANOVA test showed that the means of MR among age groups showed a negative correlation i.e. MR mean declined from 3.01 in 18-25 age groups to 2.7 in 55-65 age groups. In contrary, the gender showed no effect on MR according two sample t-test at p> 0.05. In regards with MCI, statistical analysis showed that it affected by age that is C1 was decreasing by age while C2 and C3 were increased by age. Using chi square test the result indicated that there is a significant difference among the different age group and the two genders in MCI readings. Conclusion: PMI was influenced significantly by age but minimally by the gender. MR is not affected by gender but has a negative correlation with age. MCI is affected by both age and gender

ABSTRACT Toilet training is an effort to train children to be able to control and urinate (BAK) and defecate (BAB). Toilet training is one of the main tasks of children at toddler age. Toilet training is one of the main tasks of children in toddler age which is very important to be done to create independence in children in controlling BAK and BAB and children know the parts of the body and their functions. Data in 2012 shows that ± 60% of parents do not teach toilet training to children from an early age. The aim of the study was to find out the effectiveness of toilet training education on maternal behavior and toilet skills in toddler age training (18-36 months). The study was conducted in July-August 2018. This type of quantitative research used the design of the Quasy pretest and posttest experiment with non-equivalent control group design. Samples were 36 mothers and 36 children with purposive sampling technique. Data analysis used Paired t test, Wilcoxon test, Man-Whitney test an Independent t test. The results showed that toilet training education through lecture methods, modules and maze games was more effective than toilet training education through lecture and leaflet methods on children's knowledge and abilities. Conversely, for the role of mothers in supervision there is no significant difference in effectiveness. Health education is recommended in health promotion programs to increase maternal knowledge, the role of mothers and the ability of toilet training children independently.
