Metal-Organic Framework (MOFs) are new crystalline materials which because of having propertiessuch as high porosity, optical and electrical properties, etc., have been considered in areas such as gasstorage, catalysis, pollutants removal and so on. Therefore, in order to develop these compounds andtheir use in this study, in this work, Zn-HKUST-1 metal-organic framework was synthesized by fast...
Photochemical reactions are expected to have an increasing role in organic synthesis with the drive towards environment-friendly reactions. Some examples illustrating the scope and versatility of radical alkylation of electrophilic alkenes via photoinduced electron transfer are presented. A few applications in special fields are mentioned. PHOTOCHEMISTRY FOR ORGANIC SYNTHESIS Photoinitiated rea...
many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
abstract al- muntazam by ibn al -jawzi is one of the greatest the book ancient book of texts on history of islam in the 6th century.it is very important one;because of including rare reports which are not found any where.in addition to historical reports,his outlook , in which embodies information on mythologies, milal wa nihal (sects and creeds), geography, and political, social and religiou...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
Background: The Baby-Friendly Hospital Initiative was launched in 1989 by World Health Organization and the United Nations Children's Fund for the promotion of breastfeeding. This program was implemented in many departments of gynecology and obstetrics and resulted in reduced malnutrition, infection, morbidity and mortality in children. This program has introduced 10 specific steps to support s...
Farming is an important and key factor for the economy of developing countries. Since last several years, farmers once again welcomed many traditional farming systems to get crop yield for completion of food requirement. Although, traditional techniques are not much sufficient in new agriculture world because farming is getting new challenges from biotic and abiotic factors. New techniques and ...
