Nowadays, green chemistry and its advantages are generating interest of researchers toward ecofriendly biosynthesis of the metallic nanoparticles. In this research, a rapid, simple and green method was developed for the synthesis of silver nanoparticles using aqueous extract of Prangos ferulaceae leaves. The synthesized silver nanoparticles were characterized by UV-Vis spectroscopy, sc...

objectives: the aim of this study was to assess the efficacy of aloe vera and green tea mouthwash for reducing pain after periodontal pocket reduction surgery. methods: this randomized, split-mouth, double-blind, cross-over clinical trial was carried out on 45 patients between 25 and 50 years of age requiring pocket reduction surgery. patients underwent bilateral surgeries in two sessions. afte...

In this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. The benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (CH3COO)2Cu.H2O individually as Cu sources. Al...

Recently, the subject of “green chemistry” has received considerable attention from academic and industrial researchers alike.1 While the central tenets of waste reduction, process economy and elimination of risks and hazards have long been embraced by industrial process chemists, the current focus on green chemistry concerns has led to renewed appreciation for the importance of these topics. T...

The green tract of land is one of the significant factors for urban planning and urban management to improve and conserve the urban environment. Planning the green tracts is often carried out as a part of land use strategy based on relation to neighborhood, their scale, functions, and locational condition. On the other hand, a vegetation-covered area is a considerable focus of investigation for...

Green space has been identified as a modifiable feature of the urban environment and associations with physiological and psychological health have been reported at the local level. This study aims to assess whether these associations between health and green space are transferable to a larger scale, with English cities as the unit of analysis. We used an ecological, cross-sectional study design...

nowadays, paying attention to the environmental needs and desires of consumersand trying to satisfy them by designing marketing activities in an environmentallyfriendly way, is the best way to increase their satisfaction and finally, gaincompetitive advantage. prior research has paid much attention to the consumerbehavior and marketing activities of corporate organizations, but none has studied...

Green roof technology is recognized for mitigating stormwater runoff and energy consumption. Methods to overcome the cost gap between green roofs and conventional roofs were recently quantified by incorporating air quality benefits. This study investigates the impact of scaling on these benefits at the city-wide scale using Washington, DC as a test bed because of the proposed targets in the 20-...

Fluorescence correlation spectroscopy (FCS) is a robust method for the detection of intramolecular dynamics in proteins but is also susceptible to interference from other dynamic processes such as triplet kinetics and photobleaching. We describe an approach for detection of intramolecular dynamics in proteins labeled with a FRET dye pair based on global fitting to the two autocorrelation functi...
