جهت بهینه سازی شرایط تولید پروتئین هیدرولیز شده (شامل نسبت آنزیم به سوبسترا، دما و زمان) به منظور دستیابی به بالاترین خواص آنتی اکسیدانی، مینس تهیه شده از ضایعات میگوی ببری سبز (penaeus semisulcatus) پس از تعیین درصد پروتئین آن (13%، بر اساس وزن تر) با استفاده از دو پروتئاز تجاری آلکالاز و فلاورزایم بر اساس 18 تیمار تعیین شده با طرح آزمایشات سطح پاسخ برای هر آنزیم، هیدرولیز شده و با خشک کن انجم...

By the recent growing of global trend for decentralized power generation via natural gas, the interest in joint operation of several energy carriers has substantially increased. The most significant concept in this regard is the "Energy Hub", which in this paper is employed to supply electrical and heat demands via electricity and natural gas carriers. Transformers, furnaces, combined...

In this research, the effects of B, O and B&O−doped on the SO2 gas adsorption on the surface of the (4, 4) armchair AlNNTs are investigated by using DFT method. From optimized structures the geometrical and electrical properties, adsorption energy, gap energy, global hardness, electrical potential, HOMO−LUMO orbitals, density of states (DOS) plots, electrostatic potential (ESP) plots and NMR pa...

introduction water scarcity has led to the search for alternative water resources. one solution is the recycling of wastewater for irrigation. wastewater treatment is often based on biological systems such as activated sludge or other engineered units in urban areas. in rural areas, low-cost, environmentally-friendly alternative treatments such as constructed wetlands (cw), are more common. cws...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

In recent years, the issue of energy consumption modeling techniques in the building sector has been widely considered by researchers and managers. Researches indicate that energy consumption in residential sector is one of the main parts of the total consumption. Moreover, the urban residence is supposed as a significant consumer of energy in every country and therefore a focus for energy cons...

it can be argued that fuel and energy sector plays a crucial part in the countries' development and improvement of people's living standards, constituting a pillar of economic development for nations. electricity is considered as an infrastructure for economic, social and cultural development in a way that the growth in electric power is evaluated as an indicator for measuring the gro...

Kamran Aghakhani, Maryam Ameri,

Although electrical energy is one of the best and cleanest energy sources, the proper protection and utilization of it, always and everywhere is problematic. One of the most important problems is electric shock and the dangers that can sometimes be lost in the lives of people. When a body or part of it is completely located in a strong power supply field or a contact with a device that is conne...

Large commercial and industrial loads known as large energy consumers are always seeking to reduce their energy costs and consequently they are utilizing renewable and non-renewable energy sources in procurement of their required energy. Use of renewable energy sources (RESs) and plug-in electric vehicles (PHEVs) parking lot without proper planning will make technical and economic problems for ...
