A study of the impact of strategic thinking on the performance of Mashhad municipal managers

This examines the impact of strategic thinking on the performance of Mashhad municipal mangers. Strategic thinking as one of the ways of thinking has a crucial place in the modern world and plays essential role in major issues at different organizational levels including individual decision-making and planning. We expand our horizons and take the opportunity to increase our performance using strategic thinking. Organizations are being involved in competitive and chaotic situations; therefore, they need managers with strategic thinking. Nevertheless, there are some organizations throughout the world managing their business activities in increasingly difficult situations with highly developed duties. Therefore, they need strategic thinkers to cope up with the mentioned problems and Mashhad Municipality is no exception to this policy because it has a special place among all aspects of metropolitan districts. Thus, this study has attempted to explain of the impact of strategic thinking on the performance of Mashhad municipal managers. The results obtained from the study show that strategic thinking had an acceptable level among municipal managers of Mashhad City and all factors of strategic thinking improved their performance

Cu immobilized on chitosan-modified iron oxide magnetic nanoparticles: Preparation, characterization and investigation of its anti-lung cancer effects

Chitosan is a linear polysaccharide and non-toxic bioactive polymer with a wide variety of applications due to its functional properties such as ease of modification, and biodegradability. In this study, a green protocol for supporting of Cu(II) on chitosan-encapsulated magnetic Fe3O4 nanoparticles is described. The morphological and physicochemical features of the material were determined using several advanced techniques like fourier transformed infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), inductively coupled plasma (ICP), vibrating sample magnetometer (VSM) and X-ray photoelectron spectroscopy (XPS). The average diameter of the NPs was approximately 15–25 nm. In addition, the Fe3O/CS/Cu(II) nanocomposite was engaged in biological assays like study of anti-oxidant properties by DPPH mediated free radical scavenging test using BHT as a reference molecule. Thereafter, on having a significant IC50 value in radical scavenging assay, we extended the bio-application of the desired nanocomposite in anticancer study of lung well-differentiated bronchogenic adenocarcinoma, lung moderately differentiated adenocarcinoma, and lung poorly differentiated adenocarcinoma of human lung in-vitro conditions. In the cytotoxicity and anti-human lung studies, the nanocomposite was treated to lung cancer lung well-differentiated bronchogenic adenocarcinoma (HLC-1), lung moderately differentiated adenocarcinoma (LC-2/ad), and lung poorly differentiated adenocarcinoma (PC-14) cell line following MTT assay. The cell viability of malignant lung cell line reduced dose-dependently in the presence of Fe3O/CS/Cu(II) nanocomposite. The recent results suggest that Fe3O/CS/Cu(II) nanocomposite have a suitable anticancer activity against lung cell lines
