This paper presents a model of spread sheet cost for training and development programs to the nursing staff in a hospital organization. Significant items of the total cost have been considered in relation to its elaboration and proper functioning. This model is divided into four parts: Item 1--data related to the training programs; Item 2--direct costs of these programs; Item 3--indirect costs ...

The spread of news about an epidemic can easily lead to a social panic. In order to devise measures to control such a panic, it is necessary to consider characteristics of the spread of epidemic news, based on mechanisms at the individual level. In this paper, first, some features of multi-agent simulation are reviewed. Then a multi-agent simulation model of epidemic news spread (ENS) is design...

Demographers have emphasized the importance of age in explaining spread COVID-19 and its impact on mortality. However, relationship between mortality should be contextualized relation to other causes death.

information technology as a new and very efficient tool in human communications has multiple functions that effect on public affair management is one of them. along with growth & spread of such technologies in contemporary world, this function simultaneously has spread & is changing to be an important paradigm in management & regional administration all over the world. in the other hand, good g...

The Point Spread Function (PSF) of an image forming optical system is determined by the parameters of the optical system and the distance or depth of the object being imaged. In this paper we consider the depth information in the PSF of the optical system determined by paraxial wave optics under quasi-monochromatic incoherent illumination. The spread parameter of a PSF is deened as the standard...

AIMS To assess the immunoexpression of cyclin D1 and retinoblastoma in a cohort of oesophageal squamous cell carcinoma cases from South Africa to see whether there is a relation between these two proteins. In addition, protein expression was correlated with clinicopathological features. METHODS Fifty biopsies and 30 oesophagectomy specimens were immunostained with commercially available antib...

The figure of merit for the electron optical performance of carbon-nanotube (CNT) electron sources is presented. This figure is given by the relation between the reduced brightness and the energy spread in the region of stable emission. It is shown experimentally that a CNT electron source exhibits a highly stable emission process that follows the Fowler-Nordheim theory for field emission, fixi...

A family of the spread harmonic measures is naturally generated by partially reflected Brownian motion. Their relation to the mixed boundary value problem makes them important to characterize the transfer capacity of irregular interfaces in Laplacian transport processes. This family presents a continuous transition between the harmonic measure (Dirichlet condition) and the Hausdorff measure (Ne...

The sequential correction of a fire spread model parameters is performed via the assimilation of airborne-like fire front observations in order to improve the simulation and forecast of the fire propagation. An Ensemble Kalman Filter (EnKF) is applied to reduce uncertainties in the atmospheric and vegetation parameters for the Rate Of Spread (ROS) model. The non-linear relation between the para...

During the second half of 2005, highly pathogenic avian influenza (HPAI) H5N1 virus spread rapidly from central Asia to eastern Europe. The relative roles of wild migratory birds and the poultry trade are still unclear, given that little is yet known about the range of virus hosts, precise movements of migratory birds, or routes of illegal poultry trade. We document and discuss the spread of th...
