In the present investigation natural phenolic antioxidants were extracted from Jojoba seed waste. Samples of defatted jojoba meal (JSM), detoxified residue (DMR) and shell (JSH) subjected to extraction by using various solvents: 70/30 (vol/vol) ethanol/water, methanol/water 60/40 acetone/water. Total phenolics content (TPC) is measured according Folin-Ciocalteu method. In addition, solvent extr...
در این پایان نامه به بررسی اثرات ضد دردی تعدادی از مشتقات n_اریل ایزوایندول که دارای فارماکوفر فتالامید ها هستند در دو مدل تست صفحه داغ و تزریق اسید استیک پرداخته میشود و به نظر می رسد که این ترکیبات از طریق مهار انزیم سیکلو اکسیژنار اثرات ضد دردی خود را اعمال میکنند.
the present study was an attempt to investigate varieties of cloze test and c-test as measures of reading comprehension ability. it aimed at comparing the performances of subjects on different cloze and c-test forms constructed from the same passage. to this end, five versions of cloze test and two versions of c-test were developed by applying different deletion techniques and deletion rates, a...
This work examines pressurized accelerated oxidation by a RapidOxy tester as an alternative method for determination of biodiesel stability. Sunflower oil-based was synthesized and treated with antioxidants: tert-butylhydroquinone (TBHQ) - synthetic antioxidant known its powerful protective effect, mixture bio-based compounds extracted from vinery waste, VWEeth. The potency TBHQ evaluated at va...
Arbequina extra-virgin olive oils were flavored with lemon verbena (Aloysia citrodora) essential oil (0.1–0.4%, w/w), being evaluated quality parameters (free acidity, peroxide value, UV-extinction coefficients), oxidative stability, antioxidant and total reducing capacity. The kinetic-thermodynamic nature of the lipid oxidation was by Rancimat (110–150 °C). addition promoted capacities but, un...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...

the present study was an attempt to compare the effect of peer metalinguistic corrective feedback on elementary and intermediate efl learners speaking ability to see which level benefits more from this type of feedback. to this end, 117 female efl learners at grade 3, al-zahra high school in kermanshah, iran were non-randomly chosen. the homogeneity of the participants was attained through a pi...
Improving the quantity and quality of olive oil extraction is considered crucial for producers not only in Jordan but also worldwide. The present study aimed to enhance yield from fruits without compromising its by applying an enzymatic treatment technique during malaxation stage process.
 enzymes that were used this cellulase, pectinase, a mixture both at ratio (1:1). Each there was added...
