In this study, we evaluate the different biological activities of Artemisia annua L., locally known as "Moureh", in various altitudes in North of Iran, which has been used as sedative, fever few, anti inflammation, insecticide and anti infection to treat many current diseases. Parts of plants were collected from two different localities (23-1000 m) in Mazandaran province, North of Iran. The mos...

It is argued that reliable acoustic profiles of speech under stress can only be found if different types of stress are clearly distinguished and experimentally induced. We report first results of a study with 100 speakers from three language groups, using a computer-based induction procedure that allows distinguishing cognitive load due to task engagement from psychological stress. Findings sho...

Young chickens are more susceptible to Salmonella colonization than older chickens that have developed resistance with age as native microflora become established. Elevated concentrations of cecal propionic acid and total volatile fatty acids (VFA) have been observed by many researchers to be indicators of establishment of anaerobic microflora and protection against Salmonella colonization of t...

Self-crosslinking of Tannic acid (TA) was accomplished to obtain poly(tannic acid) (p(TA)) particles in single step, surfactant free media using sodium periodate (NaIO4) as an oxidizing agent. Almost monodisperse p(TA) with 981 ± 76 nm sizes and −22 4 mV zeta potential value ellipsoidal shape obtained. Only slight degradation 6.8 0.2% observed at pH 7.4 PBS up 15 days because the irreversible c...

The aim of this research is to develop composite (CG-TA) films by using chitosan (CS)/gelatin (GL)/tannic acid (TA), for fresh-cut apples preservation. TA was used as the crossing-linking agent improve mechanical and barrier properties, active substance anti-ultraviolet antioxidant abilities chitosan/gelatin (CG) film. With incorporation from 0 1 wt%, tensile strength CG film increased while wa...

A general model is presented for the interpretation of the Raman spectra of amorphous carbon nitrides measured at any excitation energy. The Raman spectra can be explained in terms of an amorphous carbon based model, without need of extra peaks due to CN, NN or NH modes. We classify amorphous carbon nitride films in four classes, according to the corresponding N-free film: a-C:N, a-C:H:N, ta-C:...

Single β phase titanium alloys are used for fabricating biomedical devices, and it is desirable to improve the strength of these alloys. In this study, tensile Ti-35 at.% Ta with a single was improved using oxygen solid solution strengthening mechanism also investigated. The lattice constants calculated from X-ray diffraction data increased an increase in content. This result suggests that atom...

Thioacetamide (TA), a potent centrilobular hepatotoxicant, undergoes a two-step bioactivation mediated by microsomal CYP2E1 to TA sulfoxide (TASO), and further to TA-S,S-dioxide (TASO2), a reactive metabolite that initiates cellular necrosis. Our earlier studies showed that bioactivation-mediated liver injury of TA is not dose-proportional. The objective of this study was to examine whether inc...

Instructions: Failure to follow these directions may result in loss of points. • Your solutions for this assignment need to be in a pdf format and should be submitted to the blackboard and a webpage (to be specified later) for peer-reviewing. • For the programming question, your code should be well-documented, so a TA can understand what is happening. • DO NOT include any identification (your n...

'Early Rich', 'Royal Glory', 'Sweet Dream(cov)', and 'Elegant Lady' peaches were stored at -0.5 °C for up to 40 days and then subjected to ripening at 20 °C for up to 3 days. Firmness, soluble solids content (SSC), titratable acidity (TA), color, consumer acceptance, and volatile compounds were then determined. The observed physicochemical changes included a significant decrease in firmness dur...
