Identification of the appropriate dose for mutagen material is the most important step in setting experiment and creating mutant genetic material. According to a definition the most appropriate dose of mutagen is a dose that causing a reduction of 50% survival or 30% growth, compared to control. The aim of this study was to evaluate the effect of different doses of gamma radiation (0 as a contr...

In order to evaluate and compare 15 different hybrid genotypes of greenhouse tomato (Solanum lycopersicum L) in Gorgan, Golestan, north of Iran, an experiment was carried out in randomized complete block design with 3 replications at two Golestan province greenhouses (greenhouse of Gorgan Agricultural and Natural Resources Research and Education Center and a private greenhouse in Gorgan).  Inve...

target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...

this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...

The use of growth regulators and light quality change are two methods to improve plant performance. Therefore, a factorial experiment was conducted in a completely randomized design. Factors included three light modes (greenhouse light (control) and LED combination light of white: red: blue as 70: 10: 20 and 40: 40: 20 ratios) and gibberellic acid in four concentrations (0, 20, 40 and 60 mg/l)....
