since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...

in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...

Background and purpose: Bombesin is a 14-amino acid peptide with high biological functions which has a high affinity to GRP )Gastrin releasing peptide( receptor. GRP receptors are overexpressed in many malignant tumors such as prostate and breast cancers. The purpose of this study was to prepare [HYNIC-(Gly)3-D-Phe13]Bombesin(7-14) to label it easily by 99mTc and to evaluate it as a potential a...
