Biomass burning is a major and growing contributor to particulate matter with an aerodynamic diameter less than 2.5 microm (PM2.5). Such impacts (especially individual impacts from each burning source) are quantified using the Community Multiscale Air Quality (CMAQ) Model, a chemical transport model (CTM). Given the sensitivity of CTM results to uncertain emission inputs, simulations were condu...

Particle mass and number measurements in a church indicate significant increases of indoor particle concentrations during the burning of incense. Generally, varying concentration regimes can be attributed to different "modes of indoor activity" and emission sources. While periods of candle burning are negligible concerning particle concentrations, increases by a factor of 6.9 and 9.1 during inc...

The primary goals of this project are to discover management processes which benefit a restored prairie and reduce the need for prescribed burning. Moreover, because of the interdependence of the plants and soil, there is a strong focus on the soil community as a driving force of the vegetation. Consequently, our objectives were to assess the effects of manipulation (burning, mowing) on: (1) th...

background: injury is a leading cause of morbidity and mortality in children. there is insufficient data on the epidemiology or incidence of injuries in the first two years of life, especially in iran. the main objective of this study was to describe the incidence and causes of injuries in a sample group of infants and toddlers in mashhad, iran. methods: this prospective, observational study, w...

Charcoal burning has emerged as a novel suicide method in Taiwan and its impact on maternal filicide-suicide (MFS) remains unexplored. Using official national mortality data and reports of MFS cases from electronic newspaper archives, the authors aimed to examine whether the newly available charcoal burning was associated with an increase in MFS incidents during the period from 1999 to 2006. Th...

in order to compare of ecological management of weed control on economical income, yield and yield components of cotton (gossypium hirsutum l.), a randomized complete block design with 12 treatments and four replications was conducted in mahvelat of khorasan razavi province, iran. treatments consisted of weeding, harrowing, burning, two times weeding, weeding + harrowing, weeding + burning, har...

Burning mouth syndrome (BMS) can be a frustrating condition to the patient and the practitioner because the patient often experiences a continuous burning pain in the mouth without any apparent clinical signs, but the practitioner is unable to definitively diagnose symptoms even with the use of diagnostic testing or imaging. To overcome this dilemma, it is important for the practitioner to reco...

BACKGROUND A double-blind placebo-controlled trial was conducted in order to evaluate the efficacy of alpha lipoic acid (ALA) and determine the statistical significance of the outcome variables. Burning mouth syndrome (BMS) is defined as an oral burning sensation in the absence of clinical signs which could justify the syndrome. Recent studies suggest the existence of neurological factors as a ...

We investigate the evolution of metal deficient stellar structures, presenting H-burning isochrones covering cluster ages from 800 Myr to 7 Gyr. Evolutionary evidences for selection effects in the metallicity distribution of very metal poor H-burning red giants are reported. The evolution of stars during central and shell He burning is further investigated, discussing the occurrence of He burni...
