The role of airborne observatories and their study of the most basic parameters concerning Solar System bodies usually reside as footnotes in the annals of planetary science exploration. This is due in part to the high profile and obvious advantages of spacecraft observations over terrestrial platforms. However, airborne observations of the planets have a long and vibrant history. In this paper...

The Airborne Mission System in military aircraft is a complex real time system consisting of a mission control computer, sensors, displays, controls, and data buses that provide interfaces between sub-systems. The complexity and real time requirements of Airborne Mission Systems represent major challenges to the Australian Defence Force during acquisition, upgrades, and maintenance. This has mo...

OBJECTIVES The objective of the present study was to evaluate and compare the efficiency of a filter based sampling method and a high volume sampling method for sampling airborne culturable fungi present in waste sorting facilities. MATERIAL AND METHODS Membrane filters method was compared with surface air system method. The selected sampling methods were modified and tested in 2 plastic wast...

Background and Purpose: Airborne fungi are one of the most important agents responsible for triggering allergic reactions such as rhinitis and severe asthma. This study was conducted to analyze and monitor the prevalence and distribution patterns of atmospheric fungal aerosols in the air of Qazvin during winter of 2012. Materials and Methods: In the current descriptive study, the incidence ...

this paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. the study area located in semnan province of iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...

Information is limited for the exposure levels of airborne hazardous substances in swine feed buildings that are not completely enclosed. Open-style breeding, growing and finishing swine houses in six farms in subtropical Taiwan were studied for the airborne concentrations of endotoxin, dust, ammonia, hydrogen sulfide and carbon dioxide. The air in the farrowing and nursery stalls as partially ...

Exposure to elevated levels of endotoxin in family-room dust was previously observed to be significantly associated with increased wheeze in the first year of life among a cohort of 404 children in the Boston, Massachusetts, metropolitan area. However, it is likely that family-room dust endotoxin was a surrogate for airborne endotoxin exposure. Therefore, a related substudy characterized the re...

INTRODUCTION AND OBJECTIVE The presence of airborne bacteria in hospital environments is of great concern because of their potential role as a source of hospital-acquired infections (HAI). The aim of this study was the determination and comparison of the concentration of airborne bacteria in different wards of four educational hospitals, and evaluation of whether particle counting could be pred...
