Determination and analysis of vibration behavior of structures for at least first few natural frequencies and mode shapes needs several sensors to be connected at different non node points and exciting the structure at one point. Other method for determination of first few mode shapes is to excite several points of the structure at once and sensing the response from one point.  Both methods nee...

In this work a new chemically modified carbon paste electrode was constructed for accurate, simple, sensitive and selective determination of molybdenum (VI) ions. The results of modified electrode by an ion imprinted polymer were compared with those obtained with carbon paste electrode. The results showed the stripping peak currents had a dramatic increase at the modified electrode. Under the o...

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...

The stress response in Drosophila melanogaster reveals sex differences in behavior, similar to what has been observed in mammals. However, unlike mammals, the sex determination pathway in Drosophila is well established, making this an ideal system to identify factors involved in the modulation of sex-specific responses to stress. In this study, we show that the Drosophila fat body, which has be...

Gallic acid (GA) is the main phenolic antioxidant which has been subjected of many studies because of its important biological properties including anticancer, anti-inflammatory and antimicrobial activities as well as free radicals scavenger and cardiovascular diseases protector. Hereupon, fabricating a selective and sensitive sensor for GA detection and measurement is an important issue. In th...

A longitudinal study refers to collection of a response variable and possibly some explanatory variables at multiple follow-up times. In many clinical studies with longitudinal measurements, the response variable, for each patient is collected as long as an event of interest, which considered as clinical end point, occurs. Joint modeling of continuous longitudinal measurements and survival time...
