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...

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 (...

A linear-time algorithm that computes the envelope of the offset of a monotone chain is presented. The scallop hull, an extended notion of the convex hull, of the monotone chain is first computed by using an approach similar to that of the convexhull construction algorithm. The offset of the scallop hull, which yields the desired envelope, can then be computed in linear time from the scallop hu...

If X is a vector space and E is a subset of X, the convex hull of E is defined to be the intersection of all convex sets containing E, and is denoted by co(E). One checks that the convex hull of E is equal to the set of all finite convex combinations of elements of E. If X is a topological vector space, the closed convex hull of E is the intersection of all closed convex sets containing E, and ...

background: the pistachio is a nut produced by about 20 species of shrub. present-day studies show the health benefits of pistachio in preventing or treating diseases such as diabetes, cardiovascular diseases (cvds), cancer, multiple sclerosis (ms), and erectile dysfunction. materials and methods: medline / pubmed, and google scholar databases were searched using the keywords of pistacia vera, ...

Consumers' awareness about the nutritional profile of their diets has made the industry to respond their needs seriously. In this study, response surface methodology was used to analyze the effect of three fat replacers and two sweeteners on sensory attributes and viscosity of low- calorie pistachio butter. Balangu seed extract (BSG) (0.01-0.04), Reihan seed gum (RSG) (0.01-0.023), xanthan (0.0...

This article describes a 3D CFD (computational fluid dynamics) simulation implementation of the stepped planning hull in calm water. The turbulent free surface flow around the stepped planing hull is computed with a RANSE method, using the solver ANSYS-CFX. The turbulence model used is standard k–ε. In order to simulate the disturbed free surface, VOF model is implemented. The CFD model has bee...
