background: mental disorders have an important relationship with work conditions. excessive workload, laborers needs and expectations ignorance, harmful physical agents, noise, poor lightning and bad work atmosphere result increasing stress and job dissatisfaction in workers . methods: this descriptive-analytical survey implemented in order to investigate stress and job satisfaction rate of one...

The role of the atmospheric boundary layer (ABL) in the atmosphere-climate system is the exchange of heat, mass, and momentum between “the earth’s surface” and the atmosphere. Traditionally, it is understood that turbulent transport is responsible for this exchange and hence the understanding and physical description of the turbulence structure of the boundary layer is key to assess the effecti...

The photon density operator function is used to describe the propagation of single-photon pulses through a turbulent atmosphere. The effects of statistical properties of photon source and the effects of a random phase screen on the variance of photon counting are studied. A procedure for reducing the total noise is discussed. The physical mechanisms responsible for this reduction are explained.

The Ionosphere missions are the part of Ionosond-2025 space project, which main scientific objectives monitoring physical processes in Earth upper atmosphere, ionosphere and magnetosphere, as well solar activity. Within framework Ionozond-2025 it is planned to launch four spacecraft one satellite Zond. Zond be launched 2025. task mission patrol first pair early 2022, second - late 2022 or 2023....

Theoretical arguments and observations suggest that the atmospheres of Brown Dwarfs and planets are very dynamic on chemical and on physical time scales. The modelling of such substellar atmospheres has, hence, been much more demanding than initially anticipated. This Splinter1 has combined new developments in atmosphere modelling, with noval observational techniques, and new challenges arrisin...

This chapter summarizes our current understanding of the upper atmosphere and ionosphere of Saturn. We summarize the available observations and the various relevant models associated with these regions. We describe what is currently known, outline any controversies and indicate how future observations can help in advancing our understanding of the various controlling physical and chemical proce...

Free Oxygen in the Atmospheres of Mars and Venus Mark Allen, Jet Propulsion Laboratory, Califomia Institute Of Technology Yuk L. Yung, California Institute of Technology The study of the terrestrial planets has provided an opportunity to understand the factors controlling the abundance of free oxygen--primarily O2 and O3--in abiotic atmospheres. This experience should be able to guide future as...
