The main share of energy consumption in the country and more than a third of its loss is in residential use. Per capita, household electricity consumption is far from the world standard, and the existence of subsidies for energy carriers in Iran, and consequently their low prices, causes occupants to pay less attention to energy consumption. Due to the policy of eliminating subsidies, the effec...
The future distribution network comprising different energy carriers will include small-scale energy resources (SSERs) and loads, known as a Networked multi-carrier microgrid (NMCMG). This concept not only leads to an efficient reduction in operation costs, but also encompasses the energy transformation between gas and electric networks at combined nodes, as well as district heating networks. I...
Polymeric micelles, which are formed by the self-assembly of block copolymers, can load various substances and have received attention as drug carriers. Negatively charged nucleic acids such as DNA or RNA are some of the drugs delivered by polyion complex-based polymeric micelles (polyplex micelles). Polyplex micelles are expected to be nonviral gene carriers instead of viral vectors, which hav...
IIn order to study the effects of increasing level of metabolizable energy and protein on feed intake, improve nutrient digestibility, performance and blood metabolites of Zell pregnant ewes at late gestation, 32 pregnant ewe (mean body weight 42.1 kg, 2.5 years-old, multiparous, 100 days of pregnancy) were used in completely randomized design with 4 treatments and 8 replicates. Treatments were...
Pluronic/bile salt/phospholipid mixed micelles (Pluronic/BS/PS-MM) drug carrier system for solubilization hydrophobic drugs was developed. A typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. Five Pluronics, F68, F88, F98, F108, and F127 with different PPO chain length were studied. CMC data and solubilization capacities w...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
well-designed lighting decreases accidents and diseases of eyes and can increase productivity and concentration. increase of energy price and a high proportion of electric lighting energy consumption in buildings due to defects in designing and maintenance led to desirable lighting to be reduced. one of our challenges in providing health and quality of lighting is lack of economic justification...
According to international trade theories, countries attempt to produce and export commodities with their abundant resources. Iran has great energy resources and availability of inexpensive energy input has increased energy consumption per capita in manufacturing sector as well as in consuming sector. Relying on low energy price, manufacturers employ energy-intensive methods for producing and e...
This article computes the energy productivity changes of regions in Japan using total-factor frameworks based on data envelopment analysis (DEA). Since the traditional DEA-Malmquist index cannot analyze changes in single-factor productivity changes under the total-factor framework, we apply a new index proposed by Hu and Chang [2009. Total-factor energy productivity growth of regions in China. ...
