A study of the CMS hadron calorimeter is presented using simulated events with single particles and jets. The impact of the outer hadron calorimeter has been looked into from the point of view of linearity, energy resolution and leakage of energy. The study shows a net improvement in missing pT measurements at LHC energies due to the addition of the outer hadron calorimeter. 1) Tata Institute o...

We report the design and performance of the hybrid electromagnetic calorimeter for the PRIMEX experiment at Jefferson Laboratory. The detector was designed, constructed and used for high precision measurement of the lifetime of the neutral pion via the Primakoff effect. Calorimeter installation and commissioning was completed with first physics run in fall of 2004. Especially we present calorim...

Abstract Concern for the health of natural environment is growing as human population grows. Recently, renewed attention has been given to environmental impact fires and fire implications sustainability choices made in built environment. To properly understand fires, however, it crucial that we can estimate emissions. This paper explores concept emissions emission factors investigates potential...

Abstract The application of poly(lactic acid) (PLA) has been limited in flame-retardant field, and modification usually deteriorates its mechanical properties. In this study, a reactive hexa(ethylene oxide)-cyclotriphosphazene (HCCP-EP) was synthesized used to improve the fire retardancy PLA. As result, limiting oxygen index PLA increased from 19.5% 27.3% with an addition 3 wt% HCCP-EP, PLA/HCC...

Phosphorus modified polyurethane/acrylic hybrid dispersions were prepared for flame retardant transparent wood coatings. The polymerisation was carried out in three steps. In the first one, polyurethane synthesised using an acrylic monomer as solvent. second step involved water addition that promoted phase inversion and lastly, part polymerised. phosphorous compounds covalently linked to a phos...

The understanding of the reconstruction and calibration of electrons and photons is one of the key steps at the start-up of data-taking with ATLAS [1] at the LHC (Large Hadron Collider). The calorimeter cells are electronically calibrated before being clustered. Corrections to local position and energy measurements are applied to take into account the calorimeter geometry. Finally, longitudinal...

1. The heart-rate (HR) method for determining the energy expenditure of free-living subjects has been evaluated using a whole-body calorimeter in which individuals lived continuously for 27 h while carrying out normal daily activities. Eight male volunteers each occupied the calorimeter on at least two occasions when HR and energy expenditure were measured continuously. 2. After each session in...

Whis work presents a study on the flammability of epoxy coatings containing two types of nano-scale fillers as potential flame retardants: expandable graphite (EG) and halloysite nanotubes (HNTs). Both nanocomposites are prepared by incorporation of the same amount of nanofiller into the epoxy resin for the sake of comparison. Fire retardant nanocomposite coatings are cured through a two-stage ...

The hadronic shower longitudinal and lateral leakages and its effect on the pion response and energy resolution of ATLAS ironscintillator barrel hadron prototype calorimeter with longitudinal tile configuration with a thickness of 9.4 nuclear interaction lengths have been investigated. The results are based on 100 GeV pion beam data at incidence angle Θ = 10 at impact point Z in the range from ...

This paper presents the influence of selected flame retardant additives on heat release rate and thermokinetics properties epoxy materials made resin—Epidian 5. The resin underwent modification with use organophosphorus compounds (Roflam F5, Roflam B7) Al(OH)3, Mg(OH)2. fire characteristics analysed were determined using cone calorimeter method, thermal analysis surface morphology was an SEM mi...
