The hypre software library (http://www.llnl.gov/CASC/hypre/) is a collection of high performance preconditioners and solvers for large sparse linear systems of equations on massively parallel machines. This paper investigates the scaling properties of several of the popular multigrid solvers and system building interfaces in hypre on two modern parallel platforms. We present scaling results on ...

Tagged as victims of 'the world's biggest, longest running industrial disaster; dwarfing Chernobyl', 10 000 known silicosis-affected Southern African gold miners are finally set to negotiate a payout that could induce a painful paroxysm of shareholder coughing across the Johannesburg Stock Exchange.

Introduction The province of Newfoundland and Labrador is located on the east coast of Canada. The province, which has both an island and mainland portions with a total area of 505 066 square kilometres, has a population of approximately 550 000 people. With about 60% of the population living within a 150-kilometre radius of the capital region, the remainder of the province is sparsely populate...

Résumé La thrombopénie néonatale représente l’anomalie d’hémostase du nouveau-né la plus fréquente. Elle est définie par un chiffre de plaquettes inférieur à 150 000/mm. Le risque de thrombopénie néonatale concerne 40% des nouveau-nés de mère ayant des antécédents de thrombopénie auto-immune et le risque de thrombopénie sévère est évalué à 10 à 15%. Nous rapportons à travers l’observation d’un ...

A 58-year-old man had a biopsy taken in November 1998 and was diagnosed as having prostatic adenocarcinoma of Gleason score 5 (3+2); his serum PSA was 86.7 ng/mL. A DRE revealed a palpable nodule of increased consistency on the left lobe of the prostate; TRUS showed a hypoechoic area 1.5 cm in diameter in the peripheral zone of the left lobe of the prostate, with no evidence of capsular or semi...

The main aim was to assess the impact of mastitis on technical and economic results of a dairy herd under current Swedish farming conditions. The second aim was to investigate the effects obtained by withdrawing milk with high somatic cell count (SCC). A dynamic and stochastic simulation model, SimHerd, was used to study the effects of mastitis in a herd with 150 cows. Results given the initial...
