abstract foreign and iranian cultures are far distinct in the constraints imposed on writing and translating for children, since the iranian literary system is mainly concerned with cultural and religious instructions which lead to manipulation of translated texts. this study sought to identify the cultural and social constraints and norms which determined the strategies applied in the transl...
Optimal crop water requirement is needed for precise irrigation scheduling. Prediction of crop water requirements is a basic factor to achieve this goal. In this study, maize potential evapotranspiration (ETp) was prediced by maize simulation model (MSM). Then, it was evaluated and validated using experimental field data obtained in Agricultural Research Station of Shiraz University (Bajghah, F...
Many birds, alligators, and turtles spend their entire lifetimes communing between wetlands and adjacent bodies of water, while land animals that normally occupy dry land visit the wetlands to feed. Herons, eagles, sandpipers, ducks, and geese winter in marshes or rest there while migrating. The larvae of shrimp, crab, and other marine animals find shelter in the marsh from larger animals. Blue...
development in the production of agricultural products can take place in two ways: 1) increasing the inputs, which due to limitations in resources is possible only up to a specified level. the second possibility is to increase the productivity of the units by making use of new technologies. technology is defined as, substituting new ways of production for the old ones to increase production per...
â â â â â â â â â â â the recent global crisis, as a big crash ( baldwin and simon , 2009), has reduced foreign demand growth affecting total countriesâ exports. given the importance of foreign trade to nations and the reality that recent crisis has affected international trade we study the effects of the global financial crisis on trade relations between countries by using ma and cheng (200...
in this study a simple and general chemical association theory is introduced. the concept of infinite equilibrium model is re-examined and true mole fractions of associated species are calculated. the theory is applied to derive the distribution function of associated species. as a severe test the application of presented theory to the van der waals mixture model is introduced in order to perfo...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Abstract This article provides a description and an Optimality Theory (OT) analysis of contact-induced changes variation in contemporary Yoruba syllable structure. The claims that major diachronic change has occurred the structure phonology due to its continued contact with English, resulting invention, preservation, hypercorrection clusters codas. I characterize this terms OT constraint re-ran...
A triethylaluminium(TEAl)-modified Phillips ethylene polymerisation Cr/Ti/SiO2 catalyst has been developed with two distinct active regions positioned respectively in the inner core and outer shell of the catalyst particle. DRIFTS, EPR, UV-Vis-NIR DRS, STXM, SEM-EDX and GPC-IR studies revealed that the catalyst produces simultaneously two different polymers, i.e., low molecular weight linear-ch...
The reaction of copper stearate with triethylaluminurn (TEAL) formed a soluble catalyst that promoted the selective hydrogenation of the linolenyl groups in soybean oil. This homogeneous catalyst was more active than copper-chromite. The activity was enhanced by the addition of silica, alumina or titania. Ethyl alcohol accelerated the hydrogenation when it was added in small amounts and retarde...
