Environment, Energy and Environmental Productivity of Energy: A Decomposition Analysis in China and the US
The global warming, if not global burning, is a dire warning about environmental pollution
dangers to everyone, living on the only one Earth. This study aims to measure relative
contributors to the environmental quality changes during 2002-2011 using Logarithmic Mean
Divisia Index in China and the US. Since these countries are the biggest polluters in the world,
the decomposition technique is used to cut their wide environmental issues into the tiny bits of
problems, being easy to cope with. Moreover, we employed Environmental Performance Index
(EPI) to evolve the concept of Environmental Productivity of Energy (EPE). The results suggest
that economic growth and income equality are environmentally-friendly while energy
consumption is environmentally-unfriendly; and the Environmental Productivity of Energy (EPE)
and technology progress are environmentally-moody (with various effects on environment).
Consequently, the policy makers are advised to develop those economic sectors which are
independent of pollutant energies; to replace the black energies by the green ones; and to invest
on the research about the products whose demand is price inelastic
Price and Income Elasticities of Gasoline Demand in Iran: Using Static, ECM, and Dynamic Models in Short, Intermediate, and Long Run
Price and income elasticities of gasoline demand show whether the price policy, pursued by the
Iranian government, can decrease the high gasoline consumption sufficiently or not. Since the two
oil price shocks in 1970 and 1973, interest in the study of oil products demand has increased considerably,
especially on gasoline. High gasoline consumption is a serious crisis in Iran, posing
economically, politically, and environmentally threats. In this study, the elasticities are estimated
over three intervals, short run, intermediate run, and long run in Iran during 1976-2010, by putting
the estimates of Error Correction Model (ECM), static model, and dynamic model in an increasing
order, respectively. The short run, intermediate run, and long run price elasticities are
−0.1538, −0.1618, and −0.3612 and the corresponding income elasticities are 0.2273 - 0.3581,
0.4636, and 0.7284, respectively. Not only do these elasticities imply that the gasoline demand is
price and income inelastic but also the adjustment velocity, estimated by ECM, is a low point at
−0.1942. Based on the estimations, the gasoline demand responds to the changes of price and income
slightly and slowly. Therefore, policy makers should develop more strategies to reduce
gasoline consumption, for example, substitute goods, public transportation systems, and environmental
standards setting

Evaluation of Wound Dressing Made From Spider Silk Protein Using in a Rabbit Model
The aim of the present article was to study the healing of wounds using spider silk. Eight New Zealand female rabbits were selected as animal model. First, 3 identical wounds with length of 15 mm and a depth of 4 mm on the back of each rabbit were created. The first group, as standard control, did not receive any special treatment, they were treated only with saline and Vaseline locally. The second group, as positive control, received a thin film of phenytoin 1% ointment locally. The third group, as treated group, received a thin film of spider silk protein. At the end of the study, a biopsy of skin was done. After tissue preparation, all sections were evaluated. Some morphometrical parameters such as counting cells, fibroblasts, blood vessels, determination of the area of the wound closure, necrotic tissue, speed of wound healing, and epidermal thickness were done, and for data statistical analysis, SPSS software and Excel software were used. The results of this study showed that spider silk dressing may benefit as a possible effect of nanoparticles in the test preparation in wound healin
