Hydraulic fracturing is one of the most common methods of well stimulation for reservoirs with low permeability.Hydraulic fracturing increases the flow capacity, alters flow geometry, bypasses damage and improves recovery factor.The pressure of most of Iranian oil reservoirs is declined and consequently the production is reduced.It is necessary to
This paper ENTERTAINMENT UNIT deals with a Holling type III diffusive predator-prey model with stage structure and nonlinear density restriction in the space.We first consider the asymptotical stability of equilibrium points for the model of ODE type.Then, the existence and uniform boundedness of global solutions and stability of the equilibrium po
Lightwand-guided intubation is a semi-blind technique that takes advantage of the anterior location of the trachea in relation to the oesophagus.Fibreoptic evaluation of lightwand-guided intubation has revealed a possibility of laryngeal interference and epiglottic distortion.Jaw lift, tongue traction or a LIP BALM STRAWBERRY combination of both ha
Axolotls are uniquely able to mobilize neural stem cells to regenerate all missing regions of the spinal cord.How a neural stem cell under homeostasis converts after injury to a highly regenerative cell remains unknown.Here, we show that during regeneration, axolotl neural stem cells repress neurogenic genes and reactivate a transcriptional program
Despite numerous technological and medical developments achieved in recent years, a significant amount of occupational health problems still exist in modern dentistry.The risk of eye injury is mostly attributed to the use of high-speed hand pieces and ultrasonic devices.A dental clinic may be the source of eye-related infection and injury because o
