Background: Due to the importance of industrial accidents in workplaces, the current study aimed at epidemiologically investigating occupational accidents in some industrial sites in Semnan, Iran. Materials and Methods: The current descriptive-analytical study was conducted on all accidents taking place from 2014 to 2016 in some industrial sites in Semnan. The data were extracted from the Depa...
This paper will review recent progress on developing a unified theory for complex networks from biological systems and physics to engineering and technology. Insights into what the potential universal laws, architecture, and organizational principles are can be drawn from three converging research themes: growing attention to complexity and robustness in systems biology, layering and organizati...
We present a new finishing process that is capable of locally shaping and polishing optical surfaces of complex shapes. A fluid jet system is used to guide a premixed slurry at pressures less than 6 bars to the optical surface. We used a slurry comprising water and 10% #800 SiC abrasives (21.8 mum) to reduce the surface roughness of a BK7 sample from 350 to 25 nm rms and to vary the shape of a ...
Background and Aim: In order to best use from traditional medicine, world health organization suggested hygiene in making products and traditional healing method. Considering the great importance of different types of drug distillates and different uses of traditional & industrial, the amount of fungal and bacteria pollution in sweat chicory, Tp and forty traditional essences was studied in Bir...
The accurate prediction of electronic response properties of extended molecular systems has been a challenge for conventional, explicit density functionals. We demonstrate that a self-interaction correction (SIC) implemented rigorously within Kohn-Sham theory via the optimized effective potential (OEP) yields polarizabilities close to the ones from highly accurate wave-function-based calculatio...
A new simple and cheap method to grow large scale SiC-SiO2 nanocables on catalyzed Si substrate directly is presented. The method is based on the thermal decomposition of methanol. The grown nanocables consisted of crystalline 3C-SiC and amorphous SiO2. A simple etching and oxidation process was used to analyze the contribution of SiC and SiO2 components to photoluminescence.
