The main focus of the heavy flavor program at RHIC is to investigate the properties of the dense matter produced in heavy-ion collisions by studying its effect on open heavy flavor and quarkonia production. This in turn requires a detailed understanding of their production in elementary p+p collisions so that the dense matter effects can be later unfolded. In this paper, we present the first mi...

Prelacteal feeding practices are associated with an increased risk of diarrhoea and many early-life diseases. This paper examined trends and predictors of prelacteal feeding practices in Nigeria. A sample of 6416 infants aged 0-6 months from the Nigeria Demographic and Health Survey data for the period (2003-2013) was used. Trends and multilevel logistic regression analyses were used to determi...
This dissertation describes a comprehensive study of the Zγ → eeγ/μμγ/νν̄γ process. The data have been collected with the DØ detector at the Fermilab Tevatron pp̄ collider with the center-of-mass energy of 1.96 TeV, and correspond to up to 3.6 fb−1 of integrated luminosity. Firstly, in this study we perform a measurement of the Zγ production cross section. The measured cross sections in both ``γ ...
Background and purpose: Increase in cesarean section (C-Section) is a health system problem around the world. The aim of this study was to compare the rate of C-Section and indications for that before and after implementation of Health System Reform in the hospitals of Mazandaran province, Iran. Materials and methods: This descriptive cross-sectional study was conducted analytically. The indic...
