Despite its proximity to other well studied islands, Cebu has received little attention from herpetologists, most likely because of early deforestation and the perception very little natural habitat remains for amphibians and reptiles. In this study, we present a preliminary assessment of island＇s herpetofauna, focusing our field work on Cebu＇s last remaining forest fragments and synthesizing all available historical museum distribution data. We surveyed amphibians and reptile populations using standardized methods to allow for comparisons between sites and assess sufficiency of sampling effort. Fieldwork resulted in a total of 27 species recorded from five study sites, complementing the 58 species previously known from the island. Together, our data and historical museum records increase the known number of Cebu＇s resident species to 13 amphibians（frogs） and 63 reptiles（lizards, snakes, turtle, crocodile）. We recorded the continued persistence Cebu＇s rare and endemic lizard（Brachymeles cebuensis） and secretive snakes such as malayotyphlops hypogius, and Ramphotyhlops cumingii, which persist despite Cebu＇s long history of widespread and continuous habitat degradation. most species encountered, including common and widespread taxa, appeared to persist at low population abundances. To facilitate the immediate recovery of the remaining forest fragments, and resident herpetofauna, conservation effort must be sustained. However, prior to any conservation interventions, ecological baselines must be established to inform the process of recovery.

Objective:To identify the prevalence of soil-transmitted helminthiasis(STH)among school-age children in the Cagayan Valley,the Philippines,assess their level of awareness on the disease,and determine predisposing factors of the ***:A total of 478 GradesⅢ-Ⅴschool-age children in Pamplona and Sanchez-mira School Districts in the Cagayan Valley answered the questionnaire assessing their knowledge,attitude,and practices on STH,subjected to anthropometric measurements,and provided faecal samples for parasitologic assessment(direct smear,Kato-Katz,and formol-ether concentration techniques).Results:The participants of the study,with 55.86%females,were 8 to 14 years *** nutritional status was assessed‘normal’(84.31%),‘severely wasted’(6.49%),‘wasted’(5.23%),‘overweight’(2.72%),and‘obese’(1.26%).The prevalence of infection with at least 1 STH species was 25.99%in Pamplona and 19.40%in ***,the prevalence of heavy intensity was 7.11%for Ascaris lumbricoides and 1.67%for Trichuris *** hookworm infections had light *** majority of the school-age children had a low score in the KAP *** knowledge of STH,‘stunted growth as a symptom of infection’was associated with a lower risk of Ascaris lumbricoides infection(OR 0.448;95%CI 0.212,0.945;P=0.035)while‘playing with soil as a mode of transmission’was associated with an increased risk of Ascaris lumbricoides infection(OR 2.067;95%CI 1.014,4.212;P=0.046).In attitude towards STH,‘I think I have intestinal worm now’was associated with a higher risk of Ascaris lumbricoides infection(OR 1.681;95%CI 1.061,2.662;P=0.027).Conclusions:The prevalence rate of Ascaris lumbricoides among the school-age children in the Cagayan Valley shows the need to further intensify intervention in the area to meet the threshold set by the World Health *** identified predictors of infection,which concerns the school-age children’s knowledge and attitude toward STH,can be used in augmenting

On the maximum Displacement and Static Buckling of a Circular Cylindrical Shell

引用

Journal of Applied mathematics and Physics 2019年第11期7卷 2868-2882页

作者： G. E. Ozoigbo A. m. ette Department of mathematics/Computer Science/Statistics & Informatics Alex Ekwueme Federal University Ndufu-Alike Ikwo Ebonyi State Nigeria Department of mathematics Federal University of Technology Owerri Imo State Nigeria

The static buckling load of an imperfect circular cylindrical shell is here determined asymptotically with the assumption that the normal displacement can be expanded in a double Fourier series. The buckling modes considered are the ones that are partly in the shape of imperfection, and partly in the shape of some higher buckling mode. Simply-supported boundary conditions are considered and the maximum displacement and the static buckling load are evaluated nontrivially. The results show, among other things, that generally the static buckling load, λs decreases with increased imperfection and that the displacement in the shape of imperfection gives rise to the least static buckling load.
