Two experiments, one site per year, were conducted in Scotland County, North Carolina, to determine the usefulness of selected cultivars and nematicides for limiting soybean losses due to Hoplolaimus columbus. Coker 317 was relatively tolerant to this nematode, and Coker 156, Centennial, Dehapine 105, and Gordon were generally intolerant. Most nematicides significantly increased soybean yields,...

[1] The vulnerability of society on extreme weather has resulted in extensive research on the statistics of extremes. Although the theoretical framework of extreme value statistics is well developed, meteorological applications are often limited by the relative shortness of the available datasets. In order to overcome this problem, we use archived data from all past seasonal forecast ensemble r...

This response to Kress agrees that it is vital to identify gains and losses afforded by changing media but questions his reliance on binaries and periodization. It suggests a return to James Gibson’s affordances; more precise analysis of semiotic objects; and sociohistoric theories that link semiotic artifacts, individual development, and social practice. © 2004 Elsevier Inc.

A cochlear implant is an indispensable apparatus for a profound hearing loss patient. But insertion of the electrode entails a great deal of stress to the cochlea, and may cause irreversible damage to hair cells and related nerve structure. Although damage prevention effects of dexamethasone have been reported, long-term administration is difficult. In this study, we used a dexamethasone-elutin...

The currently employed cannulations preparatory to establishing cardiac bypass with the aid of a pump-oxygenator, include isolation of the superior and inferior vena cavae over tapes and the insertion of catheters into each of these vessels. t At the onset of bypass the caval tapes are tightened around the indwelling catheters and venous drainage is effected by suction applied to the venous lin...

In the open route version of the well-known vehicle routing problem, vehicles are not required to return to the depot; or if they are required, then they return by traveling the same route back. In this study, we present a modified Clarke-Wright parallel savings algorithm, a nearest insertion algorithm and a tabu search heuristic for the open vehicle routing problem with time deadlines. Some ra...

Prediction of accurate values for insertion loss (S21) on printed circuit boards has become ever more critical to SI modeling as signal speeds required for next-generation networking equipment move into the 10+ GHz range. Existing industry-standard insertion loss estimation techniques assume that the copper conductors (PCB traces) are smooth, when in fact they are not. The error thus induced is...

aim and background:   safe airway maintenance in patients under general anesthesia is the most important duty of anaesthesiologists. classic laryngeal mask airway (clma) is a supra-glottic device to achieve this aim. there are different insertion techniques for this device, but the best of them is unknown. methods and materials:   two hundred patients were included in this mono-blinded clinical...

The area of micro strip antennas has seen some inventive work in recent years and is currently one of the most dynamic fields of antenna theory. This designing is very easy and chip in micro strip antenna designing. In this paper SHF band frequencies x-band frequency 10 GHz and Kuband frequency 13GHz are gives the best result, the antenna has become a necessity for many applications in recent w...
