Emission rates and the personal cloud effect associated with particle release from the perihuman environment

Dusan Licina

Inhalation exposure to elevated particulate matter levels is correlated with deleterious health and well‐being outcomes. Despite growing evidence that identifies humans as sources of coarse airborne particles, the extent to which personal exposures are inf ...

Anthropogenic- and natural sources of dust in peatland during the Anthropocene

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

As human impact have been increasing strongly over the last decades, it is crucial to distinguish human-induced dust sources from natural ones in order to define the boundary of a newly proposed epoch -the Anthropocene. Here, we track anthropogenic signatu ...

Single florescent nanodiamond in a three dimensional ABEL trap

Aleksandra Radenovic, Metin Kayci

Three dimensional single particle trapping and manipulation is an outstanding challenge in various fields ranging from basic physics to life sciences. By monitoring the response of a trapped particle to a designed environment one can extract its characteri ...

Measurements of Submicron Aerosols at the California-Mexico Border during the Cal-Mex 2010 Field Campaign

Satoshi Takahama

We present measurements of submicron aerosols in Tijuana, Mexico during the Cal-Mex 2010 field campaign. A suite of aerosol instrumentations were deployed, including a hygroscopic-volatility tandem differential mobility analyzer (HV-TDMA), aerosol particle ...

Comminution limit (CL) of particles and possible implications for pumped storage reservoirs

Mohamed Farhat

Comminution (fragmentation) of solid particles is important in a range of technologies. An interesting effect is the so-called comminution limit (CL), which is effectively a brittle/ductile transition. Above the CL particles fail by fracture. However, as p ...

Springer2014

The US Environmental Protection Agency's (EPA) Community Multiscale Air Quality (CMAQ) modeling system version 4.7 is further developed to enhance its capability in simulating the photochemical cycles in the presence of dust particles. The new model treatm ...

Experimental proposal Test of radiation protection instrumentation in HiRadMat

Nikolaos Charitonidis, Marco Silari

The knowledge of the response of radiation protection detectors in pulsed fields is very important, since this is a typical condition often encountered with stray radiation fields around particle accelerators at CERN and elsewhere. This document presents a ...

Particle Manifold Method (PMM) for Multiscale Continuous-Discontinuous Analysis

Liang Sun

It is important to consider the microstructure of a material when studying the macroscopic mechanical properties. Although special equipments have been used for micromechanics study through experimental tests, it is limited by instruments and reproducibili ...

Deposition Processes with Hardcore Behaviour

Particles are deposited onto a surface with discrete sites. They are subject to an inhibition by which they cannot pass close by a particle already fixed on the surface. This implies that the surface builds up with vertical gaps between the particles. In t ...

Construction of the Inner Tracker and Sensitivity to the B°s -> [mu][mu] Decay at LHCb

Marc-Olivier Bettler

LHCb is one of the four main experiments hosted at the Large Hadron Collider (LHC) at CERN. The LHC first started in September 2008 and, after a one-year hiccough, restarted in November 2009. In the course of three weeks, the HEP community witnessed the fi ...
