Long-range simulation of the dispersion of air pollutants in the atmosphere is one of the most challenging tasks in geosciences. Application of precise and fast numerical models in risk management and decision support can save human lives and can diminish consequences of an accidental release. Disaster at Fukushima Daiichi nuclear power plant has been the most serious event in the nuclear techn...

Generating spatially controlled, non-destructive changes in the interstitial spaces of the brain has a host of potential clinical applications, including enhancing the delivery of therapeutics, modulating biological features within the tissue microenvironment, altering fluid and pressure dynamics, and increasing the clearance of toxins, such as plaques found in Alzheimer's disease. Recently we ...

in order to ensure the safety of parenterals, international pharmacopoeias and national standards have set up stringent guidelines and standards. particulate con- tamination is a potential health risk caused by intravenous injection of particles large enough to potentially clog the small arteries. particles could be produced through manufacturing and packaging or even dispensing of the pharmace...

Understanding the influence of synergisms on natural processes is a critical step toward determining the full-extent of anthropogenic stressors. As carbon emissions continue unabated, two major stressors--warming and acidification--threaten marine systems on several scales. Here, we report that a moderate temperature increase (from 30°C to 32°C) is sufficient to slow--even hinder--the ability o...

Diesel particulate matter (DPM) is considered to be carcinogenic after prolonged exposure. With more diesel-powered equipment used in underground mines, miners' exposure to DPM has become an increasing concern. This paper used computational fluid dynamics method to study the DPM dispersion in a dead-end entry with loading operation. The effects of different push-pull ventilation systems on DPM ...

BACKGROUND The efficacy of particulate and non-particulate steroids in patients receiving epidural steroid injections remains unclear. OBJECTIVE The purpose of this meta-analysis was to compare the efficacy of particulate and non-particulate steroids in patients receiving epidural injections for radicular pain over 3 months. STUDY DESIGN Systematic review and meta-analysis. METHODS We rev...

1. Evaluation of the meteorology: The largest concern I have with this manuscript is the lack of meteorological evaluation. The authors use two different particle dispersion models (FLEXPART & HySplit) but both are driven by the same meteorology (GFS at 0.5 ◦ × 0.5 ◦ resolution). Obviously, if the meteorology is incorrect then the authors will obtain erroneous results. Surely there are observat...

Because of their extraordinary properties, such as high thermal stability, flame retardant, high chemical resistance and high mechanical strength, thermotropic liquid crystalline polymers (TLCPs) have recently gained more attention while being useful for many applications which require chemical inertness and high strength. Due to the recent advance in nanotechnology, TLCPs are usually compounde...

The Iowa City Landfill in eastern Iowa, United States, experienced a fire lasting 18 days in 2012, in which a drainage layer of over 1 million shredded tires burned, generating smoke that impacted the surrounding metropolitan area of 130,000 people. This emergency required air monitoring, risk assessment, dispersion modeling, and public notification. This paper quantifies the impact of the fire...
