the starting behavior of a supersonic axisymmetric mixed compression air intake was numerically investigated. the code solves reynolds-averaged navier–stokes equations using an explicit finite volume method in a structured grid by the roe flux difference splitting scheme. further, it uses the baldwin–lomax algebraic model to compute the turbulent viscosity coefficient. the correct method of sur...

Adjustable throat-area expansion valves (ATAEV), including thermostatic and electric expansion valves, are used commonly in air conditioning equipment and lead to improved system performance as compared with the use of fixed orifice expansion devices. However, ATAEV modeling literature is limited. Typically, a TXV is modeled by specifying the superheat entering the compressor or empirically cor...

introduction: nausea and vomiting after ear, nose and throat (ent) surgery is one of the most common and notable problems facing anesthesiologists in this area. this study was conducted to determine the effect of a pharyngeal pack on the severity of nausea, vomiting, and sore throat among patients after ear, pharynx, and throat surgeries.   materials and methods: this randomized clinical study ...

OBJECTIVE To estimate the incidence and risk factors of group A streptococcus (GAS) sore throat among school-aged children living in a periurban slum area of Chandigarh, North India. METHODS A total of 536 children aged 5-15 years from 261 families identified by a systematic random selection method were enrolled in the study. Episodes of sore throat were recorded through fortnightly home visi...

Background. Sore throat is very common in general practice and is usually caused by viral infection. Nevertheless, up to 95% of patients may be treated with antibiotics. Previous diagnostic systems have not transferred well from one area to another because of an inability to allow for changing prevalence of streptococcus. Aim. To measure the occurrence rates of symptoms and signs in sore throat...

Adjustable throat-area expansion valves (ATAEV) are functioned as area regulator control units. In literatures, there are many expansion valves normally used in automotive air-conditioning systems, as regulator and electrical type valves. Nevertheless, a review study for such issue has not been introduced, according to the best of author knowledge. The present paper presents a review study for ...

background: sore throat is one of the major complications of tracheal intubation after general anesthesia. harpagophytum is an herbal medicine, the anti-inflammatory and analgesic effects of which have been demonstrated in various studies. we studied the effects of single dose harpagophytum one hour before tracheal intubation, to prevent the sore throat after extubation. methods: in a randomize...

BACKGROUND Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common causes of infection in the intensive care unit (ICU). Although surveillance culture for MRSA is recommended for ICU patients, no comparative study investigating the optimal sites and frequency of culture has been performed in this population. METHODS A prospective observational cohort study was performed i...
