Lack of sufficient information on conservation tillage systems leads to the dominating use of conventional tillage practice in most parts of Iran. Testing other management practices may help in decision making regarding the types of tillage systems that reduce soil deterioration. A three- years field experiment was conducted to study the effects of conventional (CT), reduced (RT) and no-till (N...
natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...
in this thesis,spin dependend transport and electron transport through of ng/sg(graphene/ superconductor graphen) are studied in the junction of ng/fgt/sg. due to andreev reflection conductance increases in the presence of superconductor graphene.also, by applying a voltage gate on a superconductor, fermi level shifts and the conductance is independent of ferromagnatic substrate. also, the cond...
Distributed data stream processing systems, like Twitter Storm or Yahoo! S4, have been primarily focusing on adapting to varying event rates. However, as these systems are becoming increasingly multi-tenant, adaptation to the varying query load is becoming an equally important problem. In this paper we present FUGU – an elastic allocator for Complex Event Processing systems. FUGU uses bin packi...
the present research has been deducted from a provincial research project which aims at determining the relationship of variables of variables of occupational self-concept, intelligence beliefs and metacognitive with entrepreneurship among the students of payame noor university of kurdistan. the volume of the samples was 1080 students (576 female and 504 male students). the research methodology...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
Despite the unprecedented mobilization of people and resources to confront the COVID-19 Phenomenon, the identification and treatment of ever-increasing number of patients has put the health systems of many countries under an unprecedented pressure beyond their capacity. On the frontline of this battle, the employees of the health systems, especially nurses are among the people who have been imp...
the search for new stationary phases has been one of the predominant concerns in high performance liquid chromatography (hplc) in order to achieve better resolutions, longer column lives, and reduce the time of analysis. a chromatographic packing for separation of underivatized amino acids (aas) were prepared by dynamically coating 2-amino tetraphenyl prophyrin (atpp) on a c-18 reversed-phase p...
this study is an outlook of iranians religious practices and customs in eras such as nasser one. it attempts to answer the main question, "religious practices and ceremonies in the society during naseri ruling" and other subsidiary questions with scientific and historical theories. iran was a traditional and religious community . people abided by their religious practices and duties within reli...
