In undertaking cultivar trials, the variability of the response of the cultivars to the di¡erent environments in which they are grown introduces the possibility of release errors and non-release errors in the decisions made on the basis of the trial results. In this article a model is developed that accounts for the economic costs of those errors as well as the costs of operating the trials, an...

Analog zum Electronic Business wird im Mobile Business zwischen Business-to-Customer(B2C) und Business-to-Business (B2B) unterschieden. Mobile B2B-Anwendungen zeichnen sich dadurch aus, dass sie zur Unterstützung von Transaktionen zwischen Unternehmen eingesetzt werden. Mobile B2B-Marktplätze und Anwendungen aus dem Bereich Telemetrie und Supply Chain Management sind hierfür Beispiele. Darüber ...

Daily transpiration rate was decreased by low soil moisture, phenylmercuric acetate (PMA) in combination with kaolinite, Mobileaf (a filmforming wax emulsion manufactured by the Mobil Oil Co.), PMA alone, and kaolinite alone in this order. At high soil moisture, dry matter was decreased by PMA but was increased by Mobileaf and by PMA + kaolinite combination. At low soil moisture, dry matter was...

Deutsche Hochschulen erweitern ihr Angebot an browserbasierten Selbstbedienungsfunktionen als Service für die Studierenden stetig. Mobile Applikationen haben aber noch keinen Einzug in den Hochschulalltag gehalten, obwohl bereits fast alle Studierenden mobil telefonieren und mobile Endgeräte darüber hinaus nicht nur zur Kommunikation nutzen, sondern multifunktional als intelligenten, persönlich...

Recent mobile devices are capable of creating and storing a large amount of multimedia data, but sharing those data with others is still challenging. This paper presents Cocktail, a new gesture-based mobile interaction system that exploits bartenders’ motions. Like a bartender who pours drinks to a glass, a user can pour (transfer) multimedia data to other device. The user can also mix music fi...

A nematicide, dibromochloropropane; the fungicides benomyl and maneb; an insecticide, oxydisulfoton; the herbicides trifluralin, linuron, and dinoseb; and fertilizers were applied to Heterodera glycines-infested soil. A resistant soybean cultivar alone produced the highest yield in one test, and its yield was not affected by application of pesticides or fertilizer. In two tests the cultivar tha...

One flavone-C-glycoside and two flavonol-O-glycosides were recognized and isolated as the main flavonoidal components in nine different carnation cultivars, and their chemical structures have been determined by spectroscopic methods, including UV detection, MS and NMR. The distribution of these three compounds in flowers, leaves, stems, young sprouts, and roots of each cultivar was evaluated by...

Pengemudi mobil sering kali mengalami kesulitan untuk memarkir di lokasi sempit, karena lahan parkir yang semakin berkurang serta tidak sedikit menabrak tiang listrik atau menggores tembok ketika mundur. Penyebabnya adalah pengemudi mengetahui kondisi belakang kendaraan keterbatasan pandangan. Penelitian bertujuan membuat sistem dapat mempermudah mobil, yaitu dengan menggunakan sensor ultrasoni...

The number of transgenic cotton cultivars available for commercial production has increased greatly in recent years. Cotton producers now have multiple choices when choosing transgenic cotton cultivars. The choice of cultivar now dictates the insect and weed control programs that will or can be used. It is estimated that, in 2003, at least 77% of Arkansas’ cotton acreage was planted to a stacke...
