This work described a simple and efficient method for the synthesis of 1-azabicyclo[3.1.0]hexane-3-ene derivatives. arylidenmalononitriles and hydroxylamine hydrochloride in the presence of NaOH, under microwave irradiation and solvent-free conditions produced the titled compounds in good to excellent yields. Using of simple chemicals, short reaction times, and solvent-free conditions, high yie...
abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
Innovativeness, determining the development potential of enterprises and economies, and hence the economic welfare of societies, became an important area of interest for both theoreticians and especially economic life practitioners. Thus, in this study of the subject there can be found numerous definitions and types of innovation, including environmental innovation, being a response to the dema...
Elite controllers (EC) of human immunodeficiency virus type 1 (HIV-1) maintain viremia below the limit of detection without antiretroviral treatment. Virus-specific cytotoxic CD8(+) T lymphocytes are believed to play a crucial role in viral containment, but the degree of immune imprinting and compensatory mutations in EC is unclear. We obtained plasma gag, pol, and nef sequences from HLA-divers...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
Turbulent fluxes of carbon, water and energy were measured at the Wind River Canopy Crane, Washington, USA from 1999 to 2004 with eddy-covariance instrumentation above (67 m) and below (2.5 m) the forest canopy. Here we present the decomposition of net ecosystem exchange of carbon (NEE) into gross primary productivity (GPP), ecosystem respiration (R(eco)) and tree canopy net CO(2) exchange (Del...
The current study emphasizes the process of synthesis of nanoparticles from the natural residue that is rapid and eco-friendly. So we present a simple and eco-friendly biosynthesis of silver nanoparticles using Ficus benghalensis fruit extract as reducing agent, rapid reduction of silver ions is observed leading to the formation of silver nanoparticles in solution. The synthesized nanoparticles...
Planning and construction are well-known practical topics; however, eco-city developments and their sustainable effects on the city are less known. Xi’an is a typical city that has a target to become an eco-city. This city is selected in this case study with the aims of (1) framing eco-practices to enhance the understanding of an eco-city development and (2) evaluating the effect of eco-practic...
Pathogenic infection in tasar silkworm, Antheraea mylitta Drury. is common and there is a breed specific response regarding tolerance. Observations reveal the possibility of differential response by haemocytes to microbial infection in different breeds. Hence, the susceptibility of three eco-races of tasar silkworm viz. Daba, Sarihan and Raily to Antheraea mylitta Cytoplasmic Polyhedrosis Virus...
