The STAR level-3 trigger is a MYRINET interconnected ALPHA processor farm, performing online tracking of N 53!#, 58000 particles (N 10*/5 445 per track) with a design input rate of R"100 Hz. A large-scale prototype system was tested in 12/99 with laser and cosmic particle events. ( 2000 Published by Elsevier Science B.V. All rights reserved.
To the careless observer and general critic the making of a law is a very easy thing. But to the actual lawmaker who meets the usual difficulties and encounters the practical obstacles it is a very different matter, and it may be of interest to many to follow the course of a bill from beginning to end.

Eurema elathea adults were census weekly (1992-1994) in six night-roosts around a forest fragment on a farm, and in two roosts in the urban area of Uberlândia, Minas Gerais, Brazil. Males were grouped in six phenotypic classes. These were based on a range between having a conspicuous wide black bar at the dorsal forewing inner margin (wet season dark morphs) and the absence of that bar (dry sea...

Background Q fever is a zoonosis with reported outbreaks in rural areas, related to farms and farm animals. In the urban area, the source of infection is almost always unknown and can be related to windborne spread of Coxiella burnetii. Objective: To emphasize the importance of Coxiella burnetii etiology in prolonged febrile syndrome. We want to point out that Q fever can become a real threat e...
Wind energy is a clean renewable and its benefits are considered greater than the disadvantages. However, even though wind farms represent environmentally friendly projects, they frequently generate public resistance. Wind turbines are socially controversial because of their visual and acoustic impacts. The aim of this work was to design a methodology for the preliminary evaluation of potential...
Farm ponds help maintain diversity in altered landscapes. However, studies on the features that drive this type of property in the Neotropics are still lacking, especially for the insect fauna. We analyzed the spatial and temporal distribution of odonate larval assemblages in farm ponds. Odonates were sampled monthly at four farm ponds from March 2008 to February 2009 in a temperate montane reg...
This study was designed to measure technical efficiency and identify its determinants in crop production in Lafia Local government Area of Nasarawa State of Nigeria using a stochastic frontier production model. Double stage random sampling technique was used to select 100 crop farmers from which input-output data were collected based on 2005 cropping season. The results revealed that sixty five...
