This paper aims to analyze tariff protection policies in the agricultural sector of developing countries. The agricultural tariff structure in developing countries is characterized by: i) high average tariffs, ii) the existence of tariff escalation, iii) dispersion of nominal tariffs across tariff lines, and iv) a wide gap between average nominal tariffs and import-weighted average tariffs. Con...

a numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. the continuity and momentum equations were solved first, assuming the wall reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. the results show that at constant inlet and...

background family planning (fp) program in pakistan has been struggling to achieve the desired indicators. despite a well-timed initiation of the program in late 50s, fertility decline has been sparingly slow. as a result, rapid population growth is impeding economic development in the country. a high population growth rate, the current fertility rate, a stagnant contraceptive prevalence rate a...

pressurized irrigation technologies of course have the potential to raise the productivity of land and water; but, these technologies could not popularize among the smallholders who own millions of farms worldwide. in developing pressurized irrigation technologies, particularly for field crops irrigation, researchers and manufacturers have developed more specialized and expensive technologies w...

background: developmental sentence scoring (dss) was developed as a numerical measurement and a clinical method based on the morphosyntactic acquisition in the english language. the aim of this study was to develop a new numerical tool similar to dss to assess the morphosyntactic abilities in persian-speaking children.   methods:  in this cross-sectional and comparative study, the language samp...
