Obstructive sleep apnea (OSA) is a condition characterized by repeated pauses in breathing during sleep, which is frequently accompanied by snoring, daytime sleepiness, and decreased concentration. Several scales, including the STOP-BANG and EPWORTH scores, have been developed to screen people at high risk for OSA. There have been few studies on both OSA risk and anthropometric characteristics, academic performance in student populations, particularly medical students.

The combination of hydrochlorothiazide (HCT), amlodipine besylate (AML) and olmesartan medoxomil (OLM) is highly effective in treating hypertension. Currently, Vietnamese Pharmacopoeia V and other reference pharmacopoeias do not have a procedure for the simultaneous quantification of these three ingredients. To develop and validate a procedure for simultaneous determination of HCT, AML and OLM in tablets by HPLC method.

In this research the effect of ground proximity on the lift, drag and moment coefficients of inverted, two-dimensional aerofoils was investigated. The purpose of the study was to examine the effect ground proximity on aerofoils post stall, in an effort to evaluate the use of active aerodynamics to increase the performance of a race car. The aerofoils were tested at angles of attack ranging from 0° – 135°. The tests were performed at a Reynolds number of 2.16 x 105 based on chord length. Forces were calculated via the use of pressure taps along the centreline of the aerofoils.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.

The nasal route for drug administration has the potential for local and systemic delivery of a wide variety of therapeutics. Nasal spray drug delivery has the potential to administer drugs to the bloodstream, avoiding the use of painful needles. While there is great potential, studies in the area are limited and somewhat conflicting. This study aimed to support the improvement of nasal drug delivery through experimental work on a model nasal cavity and through experimental characterisation of nasal spray behaviour. Four different brands of nasal spray were investigated.

Thermostable and highly water-soluble polymers are essential for polymer flooding — one of the most effective methods used in the enhanced oil recovery (EOR) in hightemperature (HT) offshore reservoirs. In this research, the copolymerization reaction of acrylamide (AM) and N-vinylpyrrolidone (NVP) monomers were performed via a freeradical mechanism induced by gamma-rays (γ-rays) irradiation.
