The aim of this paper is to measure the spatial accessibility to public health care facilities in Greece. We look at population groups disaggregated by age and socioeconomic characteristics. The purpo...
We prove that in the space of all C r (r  1) partially hyperbolic di eomorphisms, there is a C 1 open and dense set of accessible diffeomorphisms.
it takes more than the Adcp itself, however, to yield good current measurements. The end result depends on how and where the sonar is installed; on the quality of ancillary information includi...
Cholesterol is an essential component of mammalian cell membranes and it is important to regulate the structure and function of lipid bilayers. Changes in cholesterol levels are involved in many physi...
Good health is a prerequisite for global livability of man, and it is a critical component of universal needs, hence a need for equitable distribution of health facilities is a factor for sustaini...
Urban green spaces are quite significant in reducing negative effects of urbanization. They are viewed as the green lung of the city, and typically perform important functions, including absorbing...
The recently released Chandra Transmission Grating Catalog and Archive, TGCat, presents a fully dynamic on-line catalog allowing users to browse and categorize Chandra gratings observations quickly ...
The paper describes an algebraic construction of the inversive difference field associated with a discrete-time rational nonlinear control system under the assumption that the system is submersive. We...
The study evaluates the enzymatic dry matter (DM) degradability and water holding capacity of leaf and stem fractions of orchardgrass (Dactylis glomerata L.) at different growth stages with or without...
