Watermelon [Citrullus lanatus (thumb.) Matsum and Nakai] cv. Charleston gray was grafted onto three rootstocks: Cucurbita pepo, Lagenaria siceraria and (Cucurbita maxima x C. moshata). The non grafted watermelon plant was used as control. In this experiment efficiency of two kinds of grafting methods: Tube grafting and Hole insertion grafting and it was found that, Hole insertion grafting gave ...

Introduction: Hydatid Disease (HD), a helminth infection with various clinical complications is a serious economic and public health concern around the world. Nowadays, different agents have been broadly applied as scolicids; these agents have several side effects on patients. Therefore, the aims of this experimental study were to evaluate the scolicidal activity of Cucurbita maxima seeds metha...

معادلات ‎$X-AXB=C$‎ و ‎$A X+X^{*} C=B$‎ دارای کاربرد وسیعی در نظریه کنترل و سیستم های خطی می باشند. در این پژوهش به بررسی شرط ‎‎لازم و کافی برای وجود جواب آن‎‎‌ها‏ با در نظرگرفتن شرایطی پرداخته شده است. برای پیدا کردن جواب دقیق معادله دوم از نمایش ماتریسی عملگرها استفاده شده است‏، که این امکان را فراهم آورده‏، که بتوان جواب معادله را بر حسب وارون مور-...

We reflect upon an analogue of the cut locus, a notion classically studied in Differential Geometry, for finite graphs. The cut locus C(x) of a vertex x shall be the graph induced by the set of all vertices y with the property that no shortest path between x and z, z 6= y, contains y. The cut locus coincides with the graph induced by the vertices realizing the local maxima of the distance funct...

Double doped (Nd + K) ferroelectric lead germanate single crystals were grown by controlled cooling of melt. Greenish tinge crystals of 5 x 4 x 3 mm were found embedded in the solid. Pure lead germanate was grown by cz technique for comparative analysis. Dielectric constant and loss tangent of pure crystals showed a sharp dielectric peak at 179°C while dielectric constant of doped crystals show...
