The experiment was carried out during summer season of 2022 at crop research farm (CRF), Department Agronomy, SHAUTS, Prayagraj (U.P), to evaluate the influence potassium and sulphur rates on growth yield sunflower. treatments consisted 3 levels Potassium (30,40,50 kg/ha) Sulphur (10,20,30 Kg/ha) a control. used Randomized Complete Block Design (RCBD) with ten that were replicated three times. ...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
objective: at present, treatment of edentulous areas with implant-supported prosthesis has greatly increased. the aim of this study was to assess the survival rate of implants with different diameters. methods: this retrospective study was conducted on 239 warfare victims presenting to qazi tabatabaie clinic during 2000-2010. a total of 1,649 implants were placed. the success criteria included ...
The main postharvest disorder of cut gerbera flowers is the stem bending and break. The cause of stem bending is not completely clear. Although the genetic background seems to play the major role, some plant hormones such as ethylene and cytokinins may enhance or reduce the incidence of stem break during postharvest life. The choice of withstand genotypes seems to be a good strategy. In fact, s...
Foliar application or minerals is a methodology to promote growth and/or yield and protect plants against different kinds of stresses. Currently there great interest in evaluating the effect nanoparticles for enhancing these treatments. This study was performed evaluate compare foliar zinc oxide (ZnO) (ZnO-NPs) on safflower under irrigation regimes. applications ZnO all concentrations (4, 6, 8,...
Effective insect pollination requires appropriate responses to internal and external environmental cues in both the plant pollinator. Helianthus annuus, a highly outcrossing species, is marked for its uniform eastward orientation of mature pseudanthia, or capitula. Here we investigate how this affects floral microclimate consequent effects on pollinator interactions reproductive fitness. We art...
the treatment of in completely formed pulpless teeth has presented considrable problems. these teeth have wide open apexes and the walls of the root canal diverge toward the apical tissues. mechanical preparation cannot be done in the normal manner beacause of the large initial size and the taper of apical part of the canal , a mechanical stop cannot be produced at the apex of the canal and , t...
the aim of this study was to determine the combination effect of latanoprost and pilocarpine on theintraocular pressure and pupil size in normal rabbits. in this study, 18 rabbits were randomized to threegroups of 6 animals each. the right eyes of rabbits in group 1 were treated topically with latanoprost, ingroup 2 with pilocarpine and in group 3 with latanoprost and pilocarpine. the left eyes...
