About 480 million tons of rice (milled base) are produced annually in the world. It is one cereals with a low trade rate for its production. In Asia, more than 90% world's production produced. The top 10 countries all Asian countries. main operation cultivation consists planting, management while growing (weed & pest control, water management), harvesting, and post-harvest processing. addit...

It is well-known that many relevant aspects of everyday reasoning based on natural language cannot be adequately expressed in classical rst-order logic. In this paper we address two of the problems, rstly that of so-called presuppositions, expressions from which it is possible to draw implicit conclusion, which classical logic normally does not warrant, and secondly the related problem of parti...

We describe the Minimal Model Program in the family of Q-Gorenstein projective horospherical varieties, by studying a family of polytopes defined from the moment polytope of a Cartier divisor of the variety we begin with. In particular, we generalize the results on MMP in toric varieties due to M. Reid, and we complete the results on MMP in spherical varieties due to M. Brion in the case of hor...

Let Γ ⊂ X be a smooth curve on a 3-fold. In this paper we classify terminal divisorial contractions E ⊂ Y −→ Γ ⊂ X contracting an irreducible surface E onto Γ, in the case when the general section of X containing Γ has D5 type singularities. In doing so we consider the problem of existence of MMP in families of canonical 3-folds, and we get results about existence of simultaneous Q-factorialisa...

guilan province is the biggest hazelnut producer in iran. over 70% of hazelnut production cost is due to its manual harvesting. therefore, study on all aspects of its cultivation mechanization is necessary to sustain its production. this study focused on identifying factors that affect the development of hazelnut harvesting mechanization in guilan province, iran, using a three-round delphi tech...

The purpose of this study was analyzing the skill of Khoram Abad township wheat farmers regarding mechanization. This research was applied research and, based on methodology, was descriptive and correlative. Wheat farmers of Khoram Abad township, (N=18597) were considered as statistical population. Based on Krejcie and Morgan table, 377 ones were selected as sample. In this study, cluster rando...

agriculture (mechanization), food industry and environment are the concepts that cannot be surveyed separately (because of their interaction). present research aimed to study tomato paste production by applying life cycle assessment. two functional unit of kg co2-eq/ kg tomato and kg co2-eq / kg paste was used. data were collected from one paste factory in alborz province and open-field tomato ...
