The Web and Grid services frameworks provide a promising infrastructure for cross-organizational use of online services. The use of services in large-scale and cross-organizational environments requires the negotiation of agreements that define these services. Buying at a fine granularity just when a need arises is only feasible if the costs of establishing new agreements are low. Today, negoti...

1-butyl-3-methylimidazolium bromide ([bmim]br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by nabro3 in excellent yields under neutral conditions.

conclusions an approach to preventing obesity must not be enacted only in health centers. schools should also offer information and resources for families in order to prevent obesity in children. background regular body mass index (bmi) screenings in schools is important to ensure that 3- to 6-year-old children are not negatively affected by obesity in terms of their current and future health. ...

Let XI, X2, . . . be independent random variables taking values in [a, b], and let T denote the stop rules for X1, X2, Then E(sup,, X,,) sup{EX,: t E T) < (1/4)(b a), and this bound is best possible. Probabilistically, this says that if a prophet (player with complete foresight) makes a side payment of (b a)/8 to a gambler (player using nonanticipating stop rules), the game becomes at least fai...

In this paper , we evaluate a two-pass parsing strategy proposed for the so-called ' lexicalized' grammar. In ' lexicalized' grammars (Schabes, Abeill$ and Joshi, 1988), each elementary structure is systematical ly associated with a lexical i tem called anchor. These structures specify extended domains of locality (as compared to CFGs) over which constraints can be stated. The 'g rammar ' consi...

the goal of this article is mapping urban management science. the main question of the research is “what are the subject areas of urban management science and how is the relation between these subject areas?” the map of urban management science can help to recognize urban management and its subject areas and can help policy makers to get familiar with the priorities in this subject area. for th...

common bacterial blight (cbb) of bean caused by xanthomonas axonopodis pv. phaseoli is a seriously important disease that adversely affects the quantity and quality of seed. cultivation of resistant cultivars is the most effective method of  the disease control. to identify disease resistant genotypes of selected beans, an experiment was conducted in  agriculture and natural resources research ...
