Amlodipine is a dihydropyridine drug that used to lower high blood pressure. In this study, the photostabilities of orally disintegrating (OD) amlodipine tablets, both original and generic versions, their powdered suspended forms were evaluated. The concentration active pharmaceutical ingredient (API) was monitored by high-performance liquid chromatography (HPLC), revealing residual amounts API...

Motivated by field studies of the Ems estuary which show longitudinal gradients in bottom sediment concentration as high as O(0.01 kg/m), we develop an analytical model for estuarine residual circulation based on currents from salinity gradients, turbidity gradients, and freshwater discharge. Salinity is assumed to be vertically well mixed, while the vertical concentration profile is assumed to...

High-speed maglev train is considered an ideal vehicle in the 21st Century, as an important part of the train, the travel mechanism bears and delivers a variety of vertical and horizontal alternating load in operation, it affects the operation safety of the train directly, so key components of the travel mechanism should under fatigue strength test by fatigue test machine.The paper proposed a v...

The Northwest Pacific Ocean (NWPO) is a significant sink for atmospheric CO 2 but paucity of large-scale phytoplankton surveys in the upper and lower euphotic zone results uncertainties estimates efficiency biological carbon pump there. Here, we report spatial distribution lipid biomarkers from diatoms (brassicasterol/epi-brassicasterol), dinoflagellates (dinosterol), haptophytes (C 37 alkenone...

We present results of wavelength-dependent ultrafast pump-probe experiments on micelle-suspended single-walled carbon nanotubes. The linear absorption and photoluminescence spectra of the samples show a number of chirality-dependent peaks, and consequently, the pump-probe results sensitively depend on the wavelength. In the wavelength range corresponding to the second van Hove singularities (VH...

background: this study aimed to evaluate the role of efflux pump regulator and oxa-23 genes in imipenem resistance acinetobacter baumannii strains isolated from hospitalized patients in tehran, iran. methods: this study was conducted on 60 a. baumannii isolates collected from patients admitted to the shahid motahari and taleghani hospitals in tehran during 2013-14. antibiotic susceptibility tes...

We present an optomechanical method to tune phase and group birefringence in parallel silicon strip waveguides. We first calculate the deformation of suspended, parallel strip waveguides due to optical forces. We optimize the frequency and polarization of the pump light to obtain a 9 nm deformation for an optical power of 20 mW. Widely tunable phase and group birefringence can be achieved by va...

Magnetically suspended left ventricular assist devices have only one moving part, the impeller. The impeller has absolutely no contact with any of the fixed parts, thus greatly reducing the regions of stagnant or high shear stress that surround a mechanical or fluid bearing. Measurements of the mean flow patterns as well as viscous and turbulent stresses were made in a shaft-driven prototype of...
