proper application of n fertilizer and its optimization for increasing the economic yield of rice is definitely important. in order to determine the best n application method and amount according to growth stages of hybrid rice, an experiment was carried out at experimental farm of rrii in a factorial experiment based on a randomized complete block design with 3 replications. the treatments inc...

" To the '60s radical, 'Turn on, tune in, drop out' was a mantra. In these Web-happy days it could be, "Boot up, log on, download."

This paper describes preliminary conclusions from a long-term study of cultural heritage digital collections. First, those features most important to cultural heritage digital libraries are described. Second, we list those components that have proven most useful in boot-strapping new collections.

This paper develops a potential reduction algorithm for solving a linear-programming problem directly from a "warm start" initial point that is neither feasible nor optimal. The algorithm is of an "interior point" variety that seeks to reduce a single potential function which simultaneously coerces feasibility improvement (Phase I) and objective value improvement (Phase II). The key feature of ...

The clinical problem of bladder cancer is its high recurrence and progression, and that the most sensitive and specific means of monitoring is cystoscopy, which is invasive and has poor patient compliance. Biomarkers for recurrence and progression could make a great contribution, but in spite of decades of research, no biomarkers are commercially available with the requisite sensitivity and spe...

Unreliable failure detectors are a well known means to enrich asynchronous distributed systems with time-free semantics that allow to solve consensus in the presence of crash failures. Implementing unreliable failure detectors requires a system that provides some synchrony, typically an upper bound on end-to-end message delays. Recently, we introduced an implementation of the perfect failure de...

The Number Field Sieve (NFS) algorithm is the best known method to compute discrete logarithms (DL) in finite fields Fpn , with p medium to large and n ≥ 1 small. This algorithm comprises four steps: polynomial selection, relation collection, linear algebra and finally, individual logarithm computation. The first step outputs two polynomials defining two number fields, and a map from the polyno...

The identification of the application stage and correct dose 2,4-dichlorophenoxyacetic acid (2,4-D) herbicide is important so that wheat not harmed. In view this, objective this study was to evaluate effect 2,4-D doses applied at different development stages crop. experiment conducted in a randomized block design, arranged 4 × 5 factorial scheme, with four replications. factor A, (before tiller...

Improving winter wheat grain yield and water use efficiency (WUE) with minimum irrigation is very important for ensuring agricultural and ecological sustainability in the Northern China Plain (NCP). A three-year field experiment was conducted to determine how single irrigation can improve grain yield and WUE by manipulating the "sink-source" relationships. To achieve this, no-irrigation after s...
