OBJECTIVE To estimate the number of unowned free-roaming cats in a college community in the southern United States and identify the characteristics of community residents who feed these cats. DESIGN Cross-sectional, random-digit telephone survey. SAMPLE POPULATION 587 households in Alachua County, Florida, surveyed between March 1 and May 10, 1999. PROCEDURE Telephone surveys were conduct...
The dynamics of sheared inelastic-hard-sphere systems is studied using nonequilibrium molecular-dynamics simulations and direct simulation Monte Carlo. In the molecular-dynamics simulations Lees-Edwards boundary conditions are used to impose the shear. The dimensions of the simulation box are chosen to ensure that the systems are homogeneous and that the shear is applied uniformly. Various syst...
Current Italian legislation does not permit euthanasia of dogs, unless they are ill or dangerous. Despite good intentions and ethical benefits, this 'no-kill policy' has caused a progressive overpopulation of dogs in shelters, due to abandonment rates being higher than adoption rates. Shelter overcrowding has negative implications for dog welfare and increases public costs. The aim of this pape...
In the last five years, medical care policies for prisons in the Argentine Federal Penitentiary Service were developed by the previous Medical Care Assistance Office of this Institution to improve primary medical healthcare. Policies were applied with heterogeneous criteria in comparison to the ones established by the Ministry of Health. This may be why I am interested in taking a deeper look a...
The aim of this study was to evaluate health-care waste in the 18 districts of metropolitan municipality of the third biggest city in Turkey. This cross-sectional study was carried out with 825 health institutions established in the 18 districts of Izmir metropolitan municipality, in 2007. The total amount of health-care waste collected was 4841 tons and 621 kilograms per patient's bed in 2007....
This paper is devoted to the study of a generalized modified version of the well-known BevertonHolt equation in ecology. The proposed model describes the population evolution of some species in a certain habitat driven by six parametrical sequences, namely, the intrinsic growth rate associated with the reproduction capability , the degree of sympathy of the species with the habitat described by...
The approach that allows to analyse an overpopulation of phase-space in heavy ion collisions in model independent way is proposed. It gives the possibility to extract a chemical potential of thermal pi-ons at freeze out irrespective of a form of freeze-out hypersurface in Minkovsky space and transverse flows on it. The correspondent estimates , that operate correctly with contributions to phase...
Group living often entails a balance between individual selfinterest and benefits to the group as a whole. Situations in which an individual’s vested interests conflict with collective interests are known as social dilemmas (Kollock 1998). More formally, a theoretical game becomes a social dilemma when an equilibrium of dominant strategies leads to worse outcomes for all players compared to a m...
Since July 2009, there has been a community outbreak of leishmaniasis in the south-west area of the Madrid autonomous community, Spain, affecting residents from four towns that are geographically close together and share extensive park areas. As of December 2012, 446 cases were reported (6 in 2009, 97 in 2010, 196 in 2011 and 147 in 2012), a mean incidence rate of 22.2 per 100,000 inhabitants d...
Purpose of this work is to analyze oscillatory regimes in a system nonlinear differential equations describing the competition three non-antagonistic species spatially homogeneous domain. Methods. Using theory cosymmetry, we establish connection between destruction two-parameter family equilibria and emergence continuous periodic regimes. With help computational experiment MATLAB, search for li...
