BiFeO3 is a multiferroic substance which exhibits both antiferromagnetic and ferroelectric behaviour. Manganese doped Bismuth ferrite (BiFeO3) nanoparticles were prepared by using co-precipitation method, BiFeO3 was fabricated with the substitution of manganese from 10%, 20%, 30%, 40% and 50%. However, a small lattice distortion or phase change app...

Silicon solar cells with non-uniform and heavily doped emitter region have been investigated. The results show that non-uniform doped solar cells have significantly higher conversion efficiency as compared to the uniformly-doped Si-solar cells. These results were obtained from simulation with the PC1D software. By introducing non-uniform doping pro...

Image captured in bad weather conditions confines scene prominence, appears grey and diminishes image contrast. This usually happens due to atmospheric dispersing phenomenon that affects the quality of outdoor computer vision frameworks. This deprivation relies on the gap between the object point and the camera and mostly differs for every pixel pr...

In developing countries, typhoid fever is mostly seen due to poor public health and low socioeconomic indices. Currently Pakistan is going through the largest outbreak of XDR typhoid fever which has resulted in increased morbidity and mortality especially in pediatric population. Objectives: To see the pattern of extended drug resistant typhoid fev...

Hazy image observation is a serious phenomenon occurred by random scattering of atmospheric elements. This reduces the scene prominence in terms of color contrast and makes the vision system poor. To overcome this issue, dehazing of digital images is dealt with much attention in the field of computer vision. Dense scattering in hazy image results i...

Junctions or portions of blood vessels may sometimes develop weak spots because of certain factors like high blood pressure, head trauma, and infection. With time, these weak spots result in bulging or ballooning out or filling with blood creating some sac-like structures known as aneurysm. These structures can burst by leaking blood into the nearb...

Background Educational interventions to improve teamwork in crisis situations have proliferated in recent years with substantial variation in teamwork measurement. This systematic review aimed to synthesise available tools and their measurement properties in order to identify the most robust tool for measuring the teamwork performance of teams in c...

The study was conducted to conceptualize and find relationship between self-esteem and gratitude among college students. Data was collected through Rosenberg self-esteem scale and gratitude GQ6 questionnaire. 60 students from both genders were administered both questionnaires. The finding revealed that there was no significant relationship between...

The present study was carried on 6300 birth records of Kashmir Merino breed maintained at Government Sheep Breeding Farm Kralapathri and Government Sheep Breeding farm Gowbal Kashmir born to 301 sires during the years 1997-2017. The Mixed Model Least Square and Maximum Likelihood algorithms were applied to analyze the data using Harvey's statistica...

Kashmir Merino sheep is a synthetic breed developed by crossing Gaddi, Bhakarwal and Poonchi with Tasmanian and Delain Merino at Government Sheep Breeding Farm Reasi, Jammu for apparel wool, better growth and adaptability. The present investigation was undertaken to evaluate the Kashmir Merino sheep for four performance traits viz: greasy fleece yi...

Saffron (Crocus sativus L.) is a triploid sterile plant characterized by its long red stigmas, which produce and store its chief carotenoid derivatives-safranal, crocin and picrocrocin. Saffron selections of Kashmir are heterogeneous for floral characteristics which are mainly attributed to the environmental factors, though genetic factors may have...

Saffron (Crocus sativus L.) being triploid in nature is propagated by vegetative means through corms. The natural propagation rate of such plant species is relatively low, therefore some breeding and biotechnological technique like introduction, clonal selection, mutagenesis, micro-propagation and molecular markers have been used earlier as an alte...

Consider uniform flow past four slender bodies with elliptical cross-section of constant ellipticity along the length of 0, 0.125, 0.25 and 0.375, respectively, for each body. Here, ellipticity is defined as the ratio of the semiminor axis of the ellipse to the semimajor axis. The bodies have a pointed nose which gradually increases in cross-sectio...

"The purpose of this paper is to examine the effects of selected socioeconomic and demographic factors on fertility in a rural area of Bangladesh. It has been revealed that age at first marriage and coital frequency have direct significant effects while ever use of contraception and duration of breast-feeding have direct positive significant effect...

"In this paper an attempt has been made to examine fertility differentials of currently married rural women [in Bangladesh] by their socioeconomic (viz, education of women, land ownership and family type) and demographic (viz, age at the first marriage, duration of breast feeding and duration of post partum amenorrhoea for the child) characterisati...

"Data from two sources in rural Bangladesh have been used in this study to examine the differentials in fertility by selected socio-economic and demographic factors. Results [indicate] that age at first marriage, education of spouses and availability of electricity in the household...have [an] inverse relationship with fertility. Higher fertility i...

The incidence of vitiligo varies from country to country. In the present study, seventy cases of vitiligo have been studied from skin out patient department of the Institute of Post-graduate Medicine & Research over a period of 2 years. The prevalence rate of vitiligo among the total out patient attendent was 0.4 per cent. 85 per cent of the cases...
