Spatial patterning of periodic dynamics is a dramatic and ubiquitous ecological phenomenon arising in systems ranging from diseases to plants to mammals. The degree to which spatial correlations in cyclic dynamics are the result of endogenous factors related to local dynamics vs. exogenous forcing has been one of the central questions in ecology for nearly a century. With the goal of obtaining ...

in the present study, competitiveness of iranian pistachio exports and competitor countries in  the world market are studied. pistachio export advantage using indices of revealed comparative advantage (rca) approach and vector error correction model(vecm) based on  agricultural and non-petroleum export commodity basket were investigated separately. the results showed that iran has a comparative...

in this study, the situation of iran, u.s and turkey's pistachio export is investigated. to this purpose, revealed comparative advantage (rca) index is calculated based on agricultural and total economy export, separately, then forecasted by using auto- regressive integrated moving average (arima) approached, for 2008-2013. the results show that considering both commodity baskets, turkey a...

The objective of this work was to study the effect pistachio by-product flour (PBF) addition wheat on rheological properties dough. Pistachio levels used were: 0 (C), 5 (P5), 15 (P15), and 25 g/100 g (P25). Alveographic farinographic assays, gluten, moisture content (H), dough pH were studied. In addition, texture profile analysis, dynamic rheology relaxation performed. water absorption, develo...

pistachio is a major agricultural export commodity in iran. nowadays, it ranks first among iran’s agricultural exports. this paper focuses on the comparative advantage in pistachio production and the export market in iran. a policy analysis matrix (pam) framework and revealed comparative advantage (rca) index are applied to 2000-2004 data to study iranian government policy regarding pistachio p...

The genetic diversity of a large number of pistachio genotypes grown in Iran is not exactly known. Most of the studies on genetic diversity of Iranian pistachio varieties are based on morphological characteristics or isozyme markers. In the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by Amplified Fragment Length Polymorphism (...

Pistachio paste is produced from ground roasted kernel. This study focused on the influence of the milling process on colloidal stability, rheological behavior and color of pistachio paste. The colloidal stability of pistachio paste samples increased with a reduction of particle size from 31.4 to 15.10µm. The Herschel-Bulkley model was found to be the best model to describe the flow behavior of...
