Prime cost determinations can increase managerial effectiveness in budget allocation and strategic planning. This study was designed to calculate the prime cost of clinical laboratory services in Tehran Valiasr Hospital using the activity-based costing (ABC) model. The highest costs were for human recourses (44%) and the lowest for energy (5%). The largest proportion of activities (97%) was by ...

background: bio aerosols include airborne micro-organisms such as bacteria, fungi, viruses, etc and their products. exposure to a bio aerosol is linked with a broad spectrum of health problems, including infectious diseases, acute toxic effects, allergies, and cancer. the aim of this study was to evaluate the quality and quantity of bio aerosols found in the air of different wards in valiasr ho...

When upwardly mobile persons are promoted from lower, individual contributor roles to higher, managerial roles, they are confronted by the challenge of negotiating a series ofl35-degree "crossroads" or shifts in their careers. Those who make the complete journey must traverse five pathways and four crossroads. These critical career crossroads consist of discontinuous and unprecedented changes i...

1. Enrichment analyses of the unfiltered set of genes curated in HD Crossroads For the analysis presented in the main text, a filtered set of genes from HD Crossroads was used. Filtering was performed using the Target Validation Score (TVS). Genes were only included with a corresponding TVS equal or larger than 3.0, i.e. for which a causal relationship has been deduced from experiments in a HD ...

The present paper studies simulation of traffic flow in urban environment, microscopic traffic flow simulation models of street’ crossroads are made. The behaviour of cellular automata (CA) models is analyzed by means of such as indexes queue lengths at crossroads with traffic signals, flow rates, average velocities on different roads. The following indicators characterize traffic situations in...

In this article, we present a real-time machine-vision system to detect vehicles running on red light or performing forbidden turns at crossroads. The system operates during daytime by receiving video streams from two different sources. One of them is a camera viewing the crossroads to detect unusual activity, while a second camera watches the semaphore to keep synchrony with the traffic contro...
