Background: Considering the importance of standards in improving the quality of health care centers and the role of sterilization units in controlling hospital infections, especially surgical site infections, a study is done with the goal of investigating compliance of structural and functional standards in sterilization units in educational hospitals in Guilan province. Method: This analytical...
In this paper we describe a language extension that adds dimension analysis to Java. Dimension analysis can be used to check that values that represent physical measurements such as length and mass are not used inconsistently. What distinguishes this work from previous work that adds dimension analysis to programming languages is that here the extension is implemented as a composable language e...
the purpose of this study was to depict the quality of life the chronic schizophernics are experiencing in the community, with the aim of providing and appropriate care plan for these individuals. to this end the wiscosin – quality of life index (w-qli) was administered to a sample of one hundred randomly selected patients who lived within the catchment area of the shaheed esmaeili psychiatric ...
Industry is being considered as major economic element in any area. This in turn, is associated with prominent economic variables including production, employment and investment. It performs considerable role regarding environmental and social changes. More specifically, rural industries are responsible for provision of job-opportunities, prevention of rural-urban migrations, increase in econom...
The effective Lagrangian for the seesaw model is derived including effects due to CP violation. Besides the usual dimension-5 operator responsible for light neutrino masses, a dimension-6 operator is obtained. For three or less heavy neutrino generations, the inclusion of both operators is necessary and sufficient for all independent physical parameters of the high-energy seesaw Lagrangian to a...
Introduction: with the start of planning in the new form in rural areas, there is a conflict between the demand of villagers from below with the view of planners from the above that there is no normative view of issues and little attention to the environmental quality of development, that have influence on deepening the conflict. Aims: determining the dimensions of environmental quality in rura...
Let $G$ be a simple connected graph. In this paper, Szeged dimension and PI$_v$ dimension of graph $G$ are introduced. It is proved that if $G$ is a graph of Szeged dimension $1$ then line graph of $G$ is 2-connected. The dimensions of five composite graphs: sum, corona, composition, disjunction and symmetric difference with strongly regular components is computed. Also explicit formulas of Sze...
In this work, we propose a novel MIMO-aided security scheme. By exploiting an extra dimension provided by MIMO systems for adding artificial noise to the transmission process, the physical-layer security is enhanced as a result. In the proposed scheme the physical-layer may rely on upper-layer encryption techniques for security, which results in a cross-layer security scheme.
Using a combination of laboratory experiments and computer simulation we show that microwaves reflected from and transmitted through soil have a fractal dimension correlated to that of the soil's hierarchic permittivity network. The mathematical model relating the ground-penetrating radar record to the mass fractal dimension of soil structure is also developed. The fractal signature of the scat...
We consider a six-dimensional braneworld model and we study the cosmological evolution of a (4+1) braneuniverse. Introducing matter on the brane we show that the scale factor of the physical three-dimensional brane-universe is related to the scale factor of the fourth dimension on the brane, and the suppression of the extra dimension compared to the three dimensions requires the presence of dar...
