Abstract. The interplay of bio-aerosol dispersion and impact, meteorology, air quality is gaining increasing interest in the wide spectrum atmospheric sciences. Experiments conducted inside confined artificial environments, such as simulation chambers (ASCs), where conditions composition are controlled, can provide valuable information on viability, dispersion, impact. We focus here reproducibl...
A rapid compression machine (RCM) has been designed and built for investigating the autoignition characteristics of bio-derived jet and diesel fuels. The RCM has been designed with a particular emphasis on versatility, so that non-volatile fuels may be tested in a premixed gas phase, as a fuel spray, or as an aerosol in an oxidizing bath gas. A blend of these test approaches provides insight in...
background: most rural carpet weaving workshops are part of the house and sanitary conditions of the workshop not only affect the weaving but also other family members this study aimed to determine the aerosol and bioaerosols concentration in the rural household carpet weaving workshops in isfahan. methods: in this this study is a cross - sectional study and was performed in 92 rural household ...
Rationale: Mucus hypersecretion has been shown to be an important cause of airway obstruction in COPD and asthma, and has been associated with fatal asthma. Previous in-vitro and in-vivo studies have provided direct evidence that the myristoylated alanine-rich C kinase substrate (MARCKS) is a central regulatory molecule linking secretagogue stimulation at the goblet cell surface to mucin granul...
Environmental and occupational monitoring of hazardous aerosols, especially bioterrorism threats by way of dispersal of pathogenic bioaerosols, requires advanced systems that can identify harmful bioaerosol particles in quasi real-time and in situ. Instruments presently available to identify airborne biowarfare agents (BWA), mostly based on biochemical technologies, cannot be run continuously a...
Coastal area represents one of the more delicate and complex relation between natural environment and human activities. Remote sensing, offering considerable understanding of the temporal dynamics of bio-physical factors at different scale, represents a solution for monitoring the ecosystem. In particular marine phenomena, i.e. Sea Surface Temperature, chlorophyll concentration etc. can be rela...
Accurate correction of the corrupting effects of the atmosphere and the water’s surface are essential in order to obtain the optical, biological and biogeochemical properties of the water from satellite-based multiand hyper-spectral sensors. The major challenges now for atmospheric correction are the conditions of turbid coastal and inland waters and areas in which there are strongly-absorbing ...
The Bio-hydro-atmosphere interactions of Energy, Aerosols, Carbon, H2O, Organics & Nitrogen (BEACHON) project seeks to understand the feedbacks and interrelationships between hydrology, biogenic emissions, carbon assimilation, aerosol properties, clouds and associated feedbacks within water-limited ecosystems. The Manitou Experimental Forest Observatory (MEFO) was established in 2008 by the Nat...
Magnetic nanoparticles are frequently coated with SiO2 to improve their functionality and bio-compatibility in a range of biomedical and polymer nanocomposite applications. In this paper, a scalable flame aerosol technology is used to produce highly dispersible, superparamagnetic iron oxide nanoparticles hermetically coated with silica to retain full magnetization performance. Iron oxide partic...
