Trade relationships built through production chains appear to be lasting due to relation-specific nature of the transactions, compared with the usual transactions of goods sold on the open market. This paper aims to verify such stability of international production networks at the global level, with special emphasis on intra-East Asian trade. A series of survival analyses provide an evidence su...

Background: Advances in medical science and nursing care today have led to the survival of preterm infants. Therefore, it is important to address methods to reduce the duration of hospitalization of preterm infants. Aim of the systematic review on the efficacy of aromatherapy on reducing the duration of hospitalization of preterm infants. Materials an...

In recent years worldwide interest has grown towards the development of mucoadhesive drug delivery systems. These systems are capable of adhering to body's mucosal surfaces for an extended period of time, releasing their drug content in a retarded manner. The use of biopolymers, and in particular phytopolymers, could provide a natural basis for the development of such systems. The aim of this s...

This paper presents a probabilistic extension of Neighbourhood Logic (NL,[14, 1]). The study of such an extension is motivated by the need to supply the Probabilistic Duration Calculus (PDC, [10, 4]) with a proof system. The relation between the new logic and PDC is similar to that between DC [15] and ITL [12, 3]. We present a complete proof system for the new logic.

agriculture and its development is the foundation of development in iran as a developing country. so, it can be regarded as the foundation for economical and social development.the capabilities of agriculture sector are limited and its efficiency is trivial because of neglecting agricultural development and keeping its support just as a slogan. the transformation of agriculture to a developed, ...
