objective(s):cefixime (cfx), is a semi-synthetic third-generation oral cephalosporin antibiotic that is prescribed for the treatment of susceptible infections. there are some procedures for the determination of cfx in pharmaceutical formulations and biological samples. herein a spectrofluorimetric method was proposed for cfx determination based on the fluorescence quenching of terbium-danofloxa...

arid and semi-arid regions of the world are confronted with limited water resources. a large part of iran is arid and semi-arid and rainfall in arid and semi-arid regions is typically meager, irregular and highly variable. this irregularity affects the hydrological cycle and water resources. investigating the hydrology of the arid and semi arid regions is essential to know this environment and ...

Environmental impact assessment (EIA) has led to the dominance of planners on the natural environment of the regions, providing the possibility of continuously monitoring and controlling the status quo by management staff. In this regard, a new semi-quantitative model is presented for the EIA of the Eastern Alborz Coal Mining complex using the matrix method, and determining the corresponding im...

A semi-batch crystallization system is used to determine growth kinetics and morphology of barium carbonate crystals, under a constant pH value and constant temperature in the various relative supersaturations. Results show that crystal growth rate satisfies a first-order kinetic expression at high relative supersaturation, while at relative supersaturation values lower than 3,  the k...

Abstract The temperature dependent linear viscoelastic material behaviour of the most commonly used interlayer PVB is typically determined by means Dynamic-Mechanical-Thermal-Analysis (DMTA). By horizontally shifting isothermal modulus curves, a mastercurve created at certain reference temperature, which can then be mathematically approximated with Prony series. A time–temperature superposition...

manual planting of sugar-beet stecklings is a very laborious and time-consuming opera-tion. to overcome the problems, and decrease the cost of operation to a reasonable level, a semi-automatic steckling transplanter was designed. the suitability of the steckling trans-planter with regard to the agrotechnical requirements of sugar-beet stecklings was stud-ied and the main field performance param...

The present paper revisits the determination of semi-classical limit Feshbach resonances which play a role in electron impact broadening (the so-called “Stark“ broadening) isolated spectral lines ionized atoms. Gailitis approximation will be used. A few examples results provided, showing importance resonances.
