there are different studies in urban literature on the determinants of urban growth, from the theoretical and empirical points of view. the most completed theoretical model is henderson model (1988, 1997, and 1999), which is tested by some empirical studies. as henderson model shows, the set of national product, specialization and technological progress are the determinants of urban growth. usi...

the convergence hypothesis maintains that an economy whose productivity lags behind other economies has a potential to grow faster. in other words, this economy can experience faster economic growth through absorbing, accepting, and using available technology experience. in this study, we have examined the relationship between tfp of industry sectors and regional convergence in iran's prov...

This article explores the level of Women’s Empowerment (W’E) from six empowerment domains: decision-making, autonomy, access and control resources, community participation, participation in business management, within context corn-tortilla value chain. A semi-structured questionnaire was used to collect data through survey method participant observation. The sample consisted 136 women producers...

During the Physics learning process, students often have difficulty in understanding concepts, such as Electromagnetic Induction concepts. For example, assumed that a loop magnetic field B whose coil plane area shrinks towards page produces constant induced electromotive force. However, truth is when surface of reduced, force produced gets smaller. This contradiction called misconception. misco...

In year-round hot climatic conditions, conventional air conditioning systems consume significant amounts of electricity primarily generated by power plants. A compression-assisted, multi-ejector space cooling system driven low-grade solar thermal energy is investigated in terms and exergy performance, using a real gas property-based ejector model for 36 kW-scale application, exposed to annually...

Research has found out that speaking skill covered pronunciation as the fundamental significance in linguistic proficiency. Surprisingly, most English Language test, appears to be subject is often neglected. Despite generous amount of media utilize practice utterance syllable or words, supply teaching textbook source scarce. By employing research and development (R&D) 4D design, this study ...

In this paper analytical study has been made to investigate a hybrid refrigerant consists of different refrigerants with mixing ratios and find out its effects on the performance cycle specify best that gives least environmental pollution. Firstly vapor compression refrigeration system analyzed several pure refrigerants( R11, R12, R13,R22,R23, R32, R41, R115, R116, R124, R125, R134a, R142a, R14...

Introduction. The article is concerned with increasing the efficiency of energy-independent heat supply systems in agriculture through using a recovery unit thermomechanical energy converter. most promising converter thermodynamic cycle periodic action to drive diaphragm pump. For heaters and boilers, use pulsating mode carrier has double effect: it increases transfer reduces formation deposits...

The present study aimed at developing scientific literacy instruments and science learning outcomes for sixth grade elementary school students. This uses a research development design with 4-D model. results of this are, (1) In the define stage, conducting observations interviews regarding that have been used SD No. 3 Kerobokan Kaja. (2) At lattice are compiled, grid is translated into instrume...
