This paper presents the possibilities of minimizing the energy and water demand in urban areas by introducing technical changes, such as more efficient technology and local supply systems. In order to examine the effects of solutions, Musashino city, Olleof the cities in Tokyo, Japan, is used as a cage study. Urban cities, in which most of human societies exist, have developed drastically durin...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
a major concern in the last few years has been the fact that the cultural centers are keeping distance with what they have been established for and instead of reproducing the hegemony, they have turned into a place for resistance and reproduction of resistance against hegemony. because the cultural centers, as urban public spaces in the last two decades, have been the subject of ideological dis...
Today along with the growing urban population, consumption rates of energy carriers and, especially, urban electricity are increasing. In long run, this issue can cause problems in provision of such urban infrastructure. Therefore, making necessary arrangements for optimal provision of urban electricity is a significant priority for urban planners. At the same time, solar energy is one of the m...
Introduction: Urban infrastructure systems provide foundations for modern civil communities and enhance the quality of life. Coordination between different urban infrastructure agencies involved in urban infrastructure provision plays a significant role in the success of these critical urban sub-systems. It brings together various independent agencies to make their endeavors more accordant. In ...
The issue of electricity-natural gas interdependence is becoming a major energy policy and regulatory issue in all jurisdictions around the world. In this paper, we develop a model that looks at natural gas and electricity simultaneously, and apply it to the scenarios for European decarbonization at the horizon 2030/2050. The increased role of gas fired plants in RES dominated electricity marke...

thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
تهیه ترکیب فسفرتری کلرید بااستفاده از واکنش فسفر سفید(زرد) و گاز کلر در فاز محلول و درمقیاس آزمایشگاهی موردمطالعه قرارگرفت .پس از انتخاب مناسبتر روش و انتخاب بهترین شرایط کوشش درجهت طراحی واحد نیمه صنعتی انجام شد و توانستیم دراین راستا به تولید 10 کیلوگرم درساعت باخلوص 99/5 درصد برسیم . abstract the preparation of phosphorous trichloride by the reaction of white phosphorous and chlorine gas in ...
مراتع حدود نیمی از خشکی های جهان را در بر دارند و پوشش گیاهی آن در نتیجه تأثیر متقابل محیط و موجودات زنده به وجود آمده است و به عنوان یک اکوسیستم طبیعی مدیریت می شوند. علاوه بر مراتع، راه ها در عصر حاضر نیز از اجزا مهم و زیرساخت های اصلی زندگی نوین و توسعه کشورها به شمار می روند. جاده ها ساخته دست بشر هستند و جوامع گیاهی کنار جاده تحت تأثیر ساخت و ساز قرار دارند. پوشش "رودرال" به مجموعه ای از پ...
