    Analysis of Two Generalized Exponential Populations Under Joint Type-I Progressive Hybrid Censoring Scheme

    This paper discussed inference for two generalized exponential using the joint type-I progressively hybrid censoring (JPHC-I) scheme. It assumed that the lifetime distribution of the items from the two populations follow generalized exponential distribution. Based on the JPHC-I scheme, we first consider the maximum likelihood estimators of the unknown parameters along with thier asymptotic confidence intervals. Next, we provide the Bayesian inferences of the unknown parameters under the assumptions of independent gamma priors on the scale parameters using squared error (SE) and linear-exponential (LINEX) loss functions. Markov Chain Monte Carlo (MCMC) techniques is applied to carry out the Bayesian estimation procedure and in turn calculate the credible intervals. To evaluate the performance of the estimators, numerical example is carried out

    Evaluation of Genetic Diversity and Heritability of Some Rapeseed (Brassica Napus) Genotypes Using Agronomical and Molecular Traits

    High level of heritability and variability were estimated for all traits among genotypes. The genetic similarity of nine genotypes Brassica napus was estimated by random amplified polymorphic DNA (RAPD), which ranged from 69% to 94%. The phylogenetic tree resulted in two different clusters; the first including two genotypes which also showed high similarity in agronomic traits and the second included the rest of the genotypes. The genetic diversity was discussed in relation to molecular and agronomical traits. High and positive correlation were recorded for all traits. The high coupled of heritability and variability is considered as a powerful source for the selection of donors in the breeding program, where the genetic gain depends on the availability of genetic variation and high heritability

    Objective: To identify factors influencing medical student participation in an obstetrics and gynaecology (OBGYN) setting.Methods:This was a cross sectional study carried out on patients admitted in OBGYN wards of Aga Khan University Hospital, Karachi, Pakistan. A total of 250 patients consented to participate in this study.Results: Eighty three percent of the people responded \u27yes\u27 to the question of being initially seen by a medical student. People who consented were 3.5 times more likely to know that their primary consultant was a teacher at a medical school i.e. they were initially aware that they were in a teaching hospital (p-value \u3c 0.01). Additionally, people who did consent were 3.5 times more likely to have been admitted because of labour/delivery (p-value \u3c 0.001) and 2.7 times more likely to have a monthly income of more than Rs. 20,000 (p-value \u3c 0.05).Conclusions: A number of factors have been identified in our study along with proposed solutions. Identification of these potentially modifiable factors in the medical student-patient interaction is important to improve the involvement of medical students in the care of the patients
