Educated females are taking a lion share in a country’s development. In Ethiopia female students’ participation at university level is growing time to time. But, the numbers of female students who graduate from the universities are low compared with male students because of different challenges. This study was conducted with the objectives of to investigate the challenges of female students’ academic achievement in the case of Debre Markos University. To meet this objective the researcher employed on qualitative research approach with case study design method. The participants selected by using non probability sampling technique specifically purposive sampling. The data sources were primary data. Semi-structured interview and FGDs were used as a tool for collecting primary data. The data were analyzed using thematic analysis methods. The findings from the study revealed that female students are facing different challenges. Such as, institutional challenges like lack of special support, problem of academic advisor, lack of orientation, low facilities, instructors lack of teaching skills, crowded classroom, drastic life change, sexual harassment and personal challenges such as, poor socialization, lack of interest, low self-confidence, stress, poor study habit, lack of money, gender related problem, low follows up, poor language ability, lack of commitment. The study has concluded that female students are faced with many institutional and personal challenges. Based on the conclusion, recommendations are forwarded in line with the major finding of the study.","PeriodicalId":108573,"journal":{"name":"Advances in Applied Sciences","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127677601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lie, Vipin Sukumara-Pillai","doi":"10.11648/J.AAS.20190401.12","DOIUrl":"https://doi.org/10.11648/J.AAS.20190401.12","url":null,"abstract":"The safety assessment procedure in the new BS 7910:2013+A1:2015 guide is based on the failure assessment diagram (FAD) method. This paper aims to validate the above procedure for complex geometries such as damaged multi-planar square hollow section (SHS) welded joints and to recommend optimal solutions if necessary. FAD curves are constructed for cracked multi-planar SHS TT-, YT- and KT-joints for the first time and are compared with the Option 1 curve of the BS guide. A robust novel automatic finite element (FE) mesh generator, which is validated using the full-scale experimental test results, is used in this study. The new FE mesh generator addresses the issue of non-convergence by using a key-hole for the modelling the crack tip in elastic-plastic analyses. The new FE mesh generator is capable to model cracks and geometries of arbitrary dimensions and is able to achieve convergence of solutions even at a high plastic deformation. It is shown to be aiding in speedy generation of cracked FE mesh models which is otherwise time consuming to generate using commercial software packages. The results show that the Option 1 curve does not always guarantee safe solutions for multi-planar SHS welded joints. Hence, a penalty factor of 1.1 is recommended to be used to calculate the plastic collapse load. The use of proposed penalty factor gives optimal solutions for cracked multi-planar SHS TT-, YT- and KT-joints.","PeriodicalId":108573,"journal":{"name":"Advances in Applied Sciences","volume":"463 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125321358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
