extended abstract 1. introduction in dry areas, crop yield is generally low and there are limitations in fulfilling goals such as increasing the area under cultivation and reducing the cost of production. in such circumstances, the agricultural activity is limited to crops that can tolerate the harsh climatic conditions, secure farmers' income, and tolerate saline and limited water resources in...

background: pistachio is one of the main nutrients, not only as a strategic crop but also as a main type of nut, in iranians’ food cycle. the aim of this study was to measure the relative safety of iranian pistachio based on the standard pesticide’s residue limits, which should be monitored and assessed in the cultivation of pistachio in order to confirm its public health. methods: fifty sample...

Pistachio powder is a product used today in confectionery, ice cream, pistachio paste and other foods. Considering the higher rate of spoilage and oxidation in pistachio powder, developing methods to increase the shelf-life of this product is therefore important. In this study the effect of  freezing and vacuum packaging on the quality characteristics of pistachio powder during storage was inve...

In this expository paper, we survey the various approaches to compactifying moduli stacks of polarized abelian varieties. To motivate the different approaches to compactifying, we first discuss three different points of view of the moduli stacks themselves. Then we explain how each point of view leads to a different compactification. Throughout we emphasize maximal degenerations which capture m...

Let X1, . . . , Xm denote smooth projective curves of genus gi ≥ 2 over an algebraically closed field of characteristic 0 and let n denote any integer at least equal to 1 + max i=1 gi. We show that the product JX1 × · · · × JXm of the corresponding Jacobian varieties admits the structure of a Prym-Tyurin variety of exponent n. This exponent is considerably smaller than the exponent of the struc...
