OBJECTIVE To investigate the association, if any, between child mortality and distance to the nearest hospital. METHODS The study was based on data from a 1-year study of the cause of illness in febrile paediatric admissions to a district hospital in north-east Tanzania. All villages in the catchment population were geolocated, and travel times were estimated from availability of local transp...

The effects of land use and land use change on stream nitrate are poorly understood. While case studies have been presented, most process work has been done in areas with one land use (minimally disturbed or agricultural) and areas with substantial atmospheric deposition. In this paper we present results from three neighboring headwater catchments in western Oregon with similar (low) atmospheri...

It is well known that the quark-gluon plasma (QGP) produced in heavy ion collisions can be successfully described by hydrodynamics; successful hydrodynamics requires rapid thermalization with the thermalization time τ0 less than 1 fm/c [1]. Studying the dynamical processes before the formation of the QGP can provide initial conditions for the hydrodynamic simulations. During the hydrodynamic ev...

A complete history of relativistic hydrodynamics is yet to be written. Some partial accounts can be found in [1, 2]. Here, I just want to remember some seminal works which started this field, which might be called hydrodynamics applied to multiparticle production in high energy hadronic collisions. In his pioneering work of 1953 [3] Landau developed several aspects of hydrodynamics and prepaire...

In urban catchments of arid central Arizona, we investigate how the export of mineral and organic nitrogen (N) in storm runoff is regulated by interactions between local landscape characteristics and broader scale storm features. First, we test whether N export is more a function of (1) processes that affect N concentration in runoff or (2) the propensity of the catchment to convey rainfall as ...
