comparison and grouping of 32 grape cultivars and genotypes by using 61 traits including; 5 phenological and vegetative characters, 41 traits related to fruit and amount of resveratrol in 15 parts of plant was done according to grape descriptor and related methods. according to the results some traits such as spikelet weight, berry color, length of peduncle, length of berry tail, weight and len...

to evaluate effects of gibberllic acid, gridling, berry and bunch thining and their combination on fruit maturity, berry and bunch characteristics of grape cv. yaqooti an experiment was carried out using randomized complete block design with three replications in kavar, shiraz, iran, in 2010-2011 growing season. each experimental plot consisted of three vines. treatments included: t1: gibberlli...

Computer-based scaffolding is instructional support that assists students as they generate solutions to complex and ill-structured problems, goals, or tasks, helping to increase and integrate higher-order skills in the process. In this preliminary meta-analysis in STEM education, we coded 35 studies, resulting in 97 outcomes. The average effect size for scaffolding was 0.44. Performance-adapted...

The experiments described in this paper have been prompted by interest in the radiation loss of relativistic electron rings passing through periodic structures. In these experiments, single bunches of electrons with intensities up to log particles per bunch are accelerated through the SLAC three-kilometer accelerator and their energy spectrum is analyzed. Although only a limited number of measu...

The secrecy performance of realistic wireless multicast scenarios can be significantly deteriorated by the simultaneous occurrence multipath and shadowing. To resolve this security threat, in work an opportunistic relaying-based dual-hop framework is proposed which source dispatches confidential information to a bunch receivers via intermediate relays under wiretapping attempts multiple eavesdr...

A a scientist who is not a physicist and you might hear that we physicists are an arrogant bunch. And to a layperson, scientists in general often seem arrogant. No, we shrug, we’re not really arrogant, we are just very objective and thus usually right! We are certainly a group with admirable strength in our convictions. Could there be a problem with welltempered arrogance? I have worked in a nu...

The increasing ability to interconnect computers through internetworking, wireless networks, high-bandwidth satellite, and cable networks has spawned a new class of information-centered applications based on data dissemination. These applications, which often serve huge client populations, employ broadcast to efficiently deliver data to the clients. In data dissemination, the data transfer is i...

The AØ Photoinjector at Fermilab can produce high charge (10-14 nC) electron bunches of low emittance (20 mmmrad for 12 nC). We have undertaken a study of the optimal compression conditions. Off-crest acceleration in the 9-cell capture cavity induces an energy-time correlation, which is rotated by the compressor chicane (4 dipoles). The bunch length is measured using streak camera images of opt...
