the effect of learning strategies on the speaking ability of iranian students in the context of language institutes abstract language learning strategies are of the most important factors that help language learners to learn a foreign language and how they can deal with the four language skills specifically speaking skill effectively. acknowledging the great impact of learning strategies...
Two-phase flow regimes are affected by conduit position, alignment, geometry, flow direction, physical characteristics, and flow rate of each phase as well as the heat flux toward the boundaries. Due to the importance of two-phase flow, numerous regimes have been identified. The first step in studying micro-bubble formation inside a venturi tube is to recognize the type of flow regimes. In this...

Due to thermal sensitivity, costs and importance of dying process for foods, it seems to be necessary looking for new optimal approaches which could consider effects of various parameters in this research, drying process of kohlrabi in a fluid bed, exposed to air and microwave, will be analyzed using response surface method. Microwave power, temperature and flow rate of inlet air will be studie...
nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
Air-lift-pump merupakan suatu rangkaian alat yang digunakan untuk memindahkan air dan campuran (berlumpur) dari tempat ke titik lain. Sistem kerja air-lift-pump melalui media pipa dengan cara menginjeksi udara pada saluran bawah terendam. Tekanan aerator akan mendorong bergerak atas menuju arah sama melewati pipa. Cairan kental atau lumpur dapat dinaikan menggunakan air-lift-pump. Gaya apung me...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
In this paper, technique for order of preference by similarity to ideal solution(TOPSIS) method is used to find the best compromising design of intake manifold for a 3-cylinder engine considering mean value of torque, torque at 3500 rpm, mean value of brake mean specific consumption (BSFC) and BSFC at 3500 rpmas four objective functions. To calculate the objective functions, engine simulation i...
in this paper, the performance evaluation of a two-way hybrid photovoltaic/thermal (pv/t) solar collector was analytically and experimentally carried out. mathematical expressions for operating parameters in glass to glass and glass to tedlar pv/t solar collectors were developed and experimentally validated by a glass to tedlar pv/t solar collector system. also the influence of air flow rate on...
Background: In embryological culture dishes, there is a temperature decline when they are removed outside incubators. This study aimed at investigating the effects of this temperature decline within a certain time frame, the type of culture dish with or without the use of laminar air flow and whether it is possible to achieve a sufficient thermal control with the use of a heating stage. Materia...
