Background & Aims: Human cystic Echinococcosis (CE) caused by larval stage of Echinococcus granulosus, has a cosmopolitan distribution and is particularly more prevalent in rural regions. Iran is an endemic focus for CE and human cases are reported regularly from medical centers in different parts of Iran including Kerman. The objective of this study was to determine the prevalence of hydatidos...
In this study, the photocatalytic and bleaching properties of pure and doped titanium dioxide nanoparticles with 1%, 3%, 5% and 10% Ce dopant were studied using Ce(NO3)3 precursor. The results showed that the highest methylene blue degradation of the sample with 5% cerium impurity was 97% in neutral medium (pH=7) after 75 minutes. The bleaching response to wastewater treatment with 5% cerium im...
A new polyvinyl choloride (PVC) membrane sensor for cerium (III) was prepared based on 4,13-didecyl-1,7,10,16-tetraoxa-4,13-diazacyclooctadecane (kryptofix22DD) as an ionophore. The sensor exhibites a linear concentration range of 1.0×10-6 to 1.0×10-1 M, with a Nernstian slope of 18.0±1.0 mV/decade, and a detection limit of 9.7×10-7 M. It has a fast response tim...
The Kuh-e- Sefid and Banari phosphate horizons in Zagros Simply fold belt occurred in Pabdeh Formation. At this regard several samples collected from two phosphate horizons, for ICP-MS analyses. The result of ICP-MS analyses show that major oxides in two horizons are CaO> SiO2> Al2O3> Fe2O3> P2O5 respectively that the values of P2O5 in the Banari and Kuh-e- Sefid horizons is low and about 1.95 ...
this study examines the effects of organizational culture (oc) on corporate entrepreneurship (ce) among small and medium enterprises (smes). first, some models were developed to measure organizational culture and corporate entrepreneurial activities. these models measure the key factors of oc that influence personnel to initiate ce and different entrepreneurial activities that smes applied for ...
RÉSUMÉ. De nos jours, les intergiciels à composants sont utilisés pour concevoir, développer, et déployer facilement les applications réparties, et assurer l’hétérogénéité, et l’interopérabilité, ainsi que la réutilisation des modules logiciels, et la séparation entre le code métier encapsulé dans des composants et le code système géré par les conteneurs. De nombreux standards répondent à cette...
Knowledge Management (KM) is a complex objective, especially in the instance of extended enterprises consisting of SMEs, and critical in new product design and development (NPD). The use of patterns is essential to get KM in collaborative NPD processes. This paper presents the use of patterns adopted in the CE-TILE project to standardize information and knowledge in collaborative work. The diff...
The practice and study of medicine in Persia has a long and prolific history. The present study examines recorded information on the subject of medicine during the Sassanid period based on Avesta and Pahlavic texts such as Dinkard, Bundahishn, Sad dar Nasr and Sad dar Bundahishn. Moreover, Sassanid medicine was under the influences of neighboring countries such as Egypt and Greece. The Sassanid...
In this work, Ce-YIG nanoparticles with nominal composition of Y3-xCexFe5O12 (x = 0, 0.1, 0.3, 0.4, 0.5, 0.6, 0.7 and 0.8) were first fabricated by sol-gel method and then the influence of the cerium substitution on the structural and magnetic properties of garnet nanoparticles were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transform infrared (FT-IR)...
