Inspired by the excluded volume model for isospin symmetric quarkyonic matter, we construct an `excluded volume' a charge neutral phase whose hadronic sector contains only neutrons. We refer to this as neutron matter. compute equation of state and solve Tolman-Oppenhermer-Volkoff equations obtain mass radius relations relevant stars. The most straightforward extension matter does not satisfy co...
In this paper, modeling of high speed projectiles with different nose shapes, penetrating into steel fiber reinforced concrete is investigated. This is a novel study because it considers the length to diameter ratio of steel fiber as well as projectile length to diameter ratio and volume fraction of fiber used in concrete matrix on the impact resistance of steel fiber reinforced concrete fibers...
Nonalcoholic fatty liver is known in the general public as an epidemic disease. The purpose of this mini-review was to determine a link between physical education (PA) and the risk of nonalcoholic fatty liver disease (NAFLD) determine the influence of an exercise method (volume and kind of exercise) on being health outcome. Body mass index (BMI) was the good criteria for classifying obesity. I...
Urinary 1-hydroxypyrene is frequently used as a major metabolite and biological indicator of the overall exposure to polycyclic aromatic hydrocarbons. In this study, solid phase extraction was appropriately conditioned with regard to sample pH, sample concentration, loading flow rate, elution solvent, washing solvent, sample volume and sorbent mass. Octadecyl silica cartridge (C<su...
this study aimed at determining the physico-morphological attributes, in vitrofertilityand their interrelationships in semen of sahiwal bulls. semen samples werecollected weekly for 6 weeks from ten mature sahiwal bulls divided randomly into 5 groups. the mean (±sem) of ejaculate volume (ml), mass activity (score 0-5), progressive sperm motility (%), sperm concentration (106/ml), live sperm (%)...
this study presents a comparison between aluminum and iron plate electrodes on phosphate removal from aqueous solutions by electrocoagulation process. the effectiveness of main operational parameters such as initial ph, initial phosphate concentration and current density were examined. in addition, treated solution and sludge characteristics, energy consumption and electrode mass depletion were...
