to identify the impacts of chemical control of weeds on wheat aphids community, a field experiment was conducted in a completely randomized design with two factors, each in three replicates in a 20-ha wheat field. the herbicide treatment used tribenuron methyl, a broadleaf–selective herbicide and the control treatment not treated with herbicide. all other agricultural practices were the same fo...

Before the 1981 growing season, a s tudy was instal led in southeastern Arkansas to examine the eflects of three dormant-season burn intervals ( low, moderate, and highfrequency) and an unburned treatment on natural regeneration in uneven-aged stands of loblolly and shortleaf pines (Pinus taeda and P. echinata, respectively) . Merchantable pine basal areas were maintained by harvest ing on a 5 ...

A hydroxamate type siderophore producing fluorescent Pseudomonas strain, isolated from the rhizoplane of paddy root showing plant growth promoting activity, exhibited a decreased in vitro antibiosis, production of siderophore and suppression of collar rot in presence of metham sodium. Use of herbicide had a detrimental effect on the plant growth promoting activity of this organism. The multiple...

Due to the importance of collective communications in scientific parallel applications, many strategies have been devised for optimizing collective communications for different kinds of parallel environments. Recently, there has been an increasing interest to evolve efficient broadcast algorithms for computational Grids. In this paper, we present application-oriented adaptive techniques that ta...

Use of efficient methods of weed control with as regards environmental sustainability as well as increased crop yield and also weed resistance to herbicides is essential. In order to, an experiment was conducted in 2012 in the Damavand jaban in Iran. Experiment treatments were compared in a split plot design by a randomized completely block design with 3 replication. The used variety of maize w...

Abstract The objective of this work was to evaluate the effects application glyphosate herbicide on seed reserve mobilization and seedling morphology genetically modified soybean. Two herbicide-tolerant (TMG 1264RR P98Y11) two herbicide-sensitive (Emgopa 315 UFUS 7415) cultivars were selected for study subjected germination, length, tests after treatments with solutions at concentrations 0.00, ...

LTE broadcast is a communication standard which is expected to revolutionize the multimedia service provision in the future. The distinctive features of this standard such as increased service capacity, high spectral efficiency, and spectral adjustability have encouraged many companies to select this standard for the future generation broadcasting. In this paper, after a complete introduction o...

Because network-level reliable group communication protocols rely on IP multicast and have lack of reliability, this motivates the demand on application-level group communication. Epidemic-style protocols among these application-level approaches guarantee reasonably high reliability, provide good scalability and are easy to deploy. But, earlier versions of these protocols often rely on the assu...

This paper describes the design and application of time-enhanced, finite state models of discourse cues to the automated segmentation of broadcast news. We describe our analysis of a broadcast news corpus, the design of a discourse cue based story segmentor that builds upon information extraction techniques, and finally its computational implementation and evaluation in the Broadcast News Navig...
