Geometric an. micro-structure design. tribology properties of beetle join.s were experimen.ally studied, which aimed to en.ighten.ideas for the join. design.of *** observation.by usin. SEM an. microscopy suggested that beetle's join.s con.ist of a con.ave surface matched with a con.ex surface. The heads of the beetles, rubbin. with flat glass, were tested in.fresh an. dried statuses an. compared with sapphire ball with flat glass. Friction.l coefficien. of the join. material on.glass was sign.fican.ly lower than.that of the sapphire sphere on.glass. The material of the join. cuticle for con.ex surface is rather stiff (the elastic modulus 4.5 Gpa) an. smooth. The surface is hydrophobic (the con.act an.le of distilled water was 88.3° ). It is suggested here that the high stiffn.ss of the join. material an. hydrophobicity of the join. surface are parts of the mechan.sm min.mizin. friction.in.in.ect join.s.

Water samples from chromite min. quarry of Sukin.a an. its adjacen. areas were an.lyzed for their heavy metal con.amin.tion.alon. with physico-chemical an. microbial con.en.s. The chromite min. water samples possessed high con.en.ration. of heavy metals in.the order of Cr〉Fe〉Zn.n.〉Co〉Mn.while groun. water did n.t show an. heavy metal con.amin.tion.except Fe. Physico-chemical parameters of min. water samples showed deviation.from those of n.rmal water. Min. water harboured low microbial population. of bacteria, fun.i an. actin.mycetes in.comparison.with min. adjacen. water samples. The correlation.of data between.metals with physico-chemical parameters showed both positive an. n.gative respon.es while that of metal an. microbial population.exhibited n.gative correlation. Bacterial strain. isolated from chromite min. water exhibited high toleran.e towards chromium an. other heavy metals as well as an.ibiotics which could be used as an.in.icator of heavy metal pollution.

n.>Backgroun.:n.> One of the key strategies in the HIV/AIDS prevention and control programs in Nigeria is Voluntary HIV counseling and testing (VCT). However, its utilization among young adults, particularly undergraduates, is very low. The aim of the present study was to determine the prevalence and predictors of non-uptake of VCT among undergraduates. Methods: A cross sectional study using quantitative methods was conducted. Using simple random sampling, three faculties were selected out of nine and 422 respondents were selected from three faculties. Interviews were conducted using pre-tested semi-structured questionnaires. Data analysis was done using statistical package for social sciences version 20. Prevalence was measured by the percentage of respondents that had never used VCT. Analytical statistics were done using chi-square test to measure strength of association between VCT uptake and knowledge and attitude of respondents. Association with P-valuen. 0.05 was considered significant. Logistic regression was used to identify predictors of non-uptake of VCT. The associations were presented as odds ratios (OR) and 95% confidence intervals. Results: Overall, 59.3% of respondents were knowledgeable about VCT while majority, 64.7% had negative attitude towards it. Knowledge (X2 = 9.89, P-value 2n.style="fon.-family:Verdan.;"> = 10.78, P-

Main.Objective: To determin. the prevalen.e of thumb suckin. habits amon.st children.at the Kn.ST Basic School. Methodology: This study was quan.itative an. descriptive with the design.bein. a cross-section.l type. The data was obtain.d from Kn.ST Basic School with a sample size of 200. Data was obtain.d through question.aires an. clin.cal examin.tion. Results: Out of the 200 children.studied, 19 (9.5%) were iden.ified as thumb suckers, with a majority bein. females (13, 68.42%) an. the rest bein. males (6, 31.58%). Most of the thumb suckers (47.37%) en.aged in.the habit due to hun.er. The clin.cal man.festation. observed amon. the thumb suckers in.luded Class I malocclusion.(94.7%), high arched palate (89.5%), an.erior open.bite (4), in.reased overjet (3, 15.8%), proclin.d maxillary in.isors (4, 22.2%), lin.uoversion.of man.ibular in.isors (1, 5.6%), un.lateral posterior crossbite (2, 10.5%), speech chan.es (7, 41.2%), thin.er thumb (7, 36.8%), elon.ated thumb (9, 47.4%), an. callus formation.on.the thumb (2, 10.5%). Con.lusion. Thumb suckin. is a common.oral habit which stimulates the growth of the orofacial complex from ages 0 to 3 years. The habit of thumb suckin. is usually outgrown.by age 3 but beyon. this age, it turn. out as a deleterious habit which has to be seen.as such an. measures put in.place to stop thumb suckin..
