The substitution reactions of the tetrahedral Fe sites in [FeCl(4)](-), [Fe(2)S(2)Cl(4)](2-), [Fe(4)S(4)Cl(4)](2-) and [{MoFe(3)S(4)Cl(3)}(2)(micro-SEt)(3)](3-) with 4-RC(6)H(4)S(-) (R = MeO, Me, H, Cl or NO(2)) all involve rapid binding of the thiolate to a Fe site and formation of a kinetically and spectroscopically detectable intermediate. Kinetic studies allow calculation of the rate of Fe-...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
mn(tpp)cl catalyzes cooxidation of olefin in the singlet oxygenation of sulfid. mn(tpp)cl is able to transfer an oxygen atom from a peroxidic intermediate generated in singlet oxygenation of sulfide to a metal ion affording metal 0x0 species which is responsible for epoxidation. this system leads to allcenes epoxidation such as styrene and cyclooctene. epoxidation of cyclohexene produces cycloh...
For any number field K with non-elementary 3-class group Cl(3,K) = C(3^e) x C(3), e >= 2, the punctured capitulation type kappa(K) of in its unramified cyclic cubic extensions Li, 1 <= i 4, is an orbit under action S3 S3. By means Artin's reciprocity law, arithmetical invariant translated to transfer kernel kappa(G2) automorphism G2 Gal(F(3,2,K)/K) second Hilbert K. A classification finite 3-gr...
We have recently demonstrated that the anti-proliferative effect of interferon (IFNg) in RCC is due to an increased production of nitric oxide (NO) which in turn inhibits the induction of arginase (ARG2). The growth of cultured murine RCC cell lines was inhibited in 85% in IFNg treated when compared to un-treated cells. In contrast only 33% of these cells were inhibited by IFNg. These results i...
We performed low-resolution spectroscopy for the red giant branch stars in an intriguing globular cluster (GC) NGC 2808, which hosts subpopulations with extreme helium and light-element abundances. In order to trace N, C, Ca abundance differences among subpopulations, we measured CN, CH, ii H&K spectral indices, respectively. identified four (G1, G2, G3, G4) from CN CH strength, CN-weak/CH-stro...
why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...

Background and Aims: Cutaneous leishmaniosis (CL) is a neglected tropical vector-borne disease. As other vector-transmitted diseases, its transmission is sensitive to the physical environment. The purpose of this study was to investigate the relationship between El Niño-Southern Oscillation (ENSO) and annual incidence of CL in Iran. Materials and Methods: The data of ENSO were obtained from ...
The N-terminal fragment (G1-G2) of cartilage proteoglycan protein core contains two globular domains, binding region (G1) and a second globular domain (G2), G1-G2 was isolated after mild trypsin digestion of purified proteoglycan aggregates followed by chromatography first on Sepharose CL-2B under associative conditions and then on a TSK-4000 column in 4 M-guanidinium chloride. It migrated as a...
