Nano-crystalline metals performance of defects and mechanisms of plastic deformation and conventional polycrystalline are completely divergent in behavior and its perfor-mance. This paper discusses about grain boundary and dislocation mediated deformation me-chanisms in Nano-crystalline metals. The plots are for burger vectors of single value, Gaussian and uniform characteristics considering various parameters such as elastic constants, plasticity, loading condition and uncertainty quantification.Introduction People Living With HIV make up the most important group to address HIV Prevention. Simultaneous protection against both unwanted pregnancy and STIs/HIV is referred to as dual contraceptive. Therefore, dual protection with the use of effective modern contraceptive method together with condom is critical.

Objectives:- To assess the prevalence and associated factors of dual contraceptive use among HIV positive reproductive aged women (15-49) in Metekle Zone, west Ethiopia.

Methods: Institutional based cross-sectional study was conducted. Systematic sampling technique was used to get 403 participants. Data were analyzed using SPSS version 20. Logistic regression was used to check variable having association dual-contraceptive use.

Results:- Of the 403 PLHIV women,99.5% had heard about modern contraceptive, but only 273(58.8%) had heard about dual contraceptive, out of which 165 (40.9%) had reported using dual methods. The common reason not to use dual method was lack of knowledge 174(73.1%).

Conclusions: -Less than half used dual methods. Awareness creation on dual contraceptive use should be given attention.
