Utilization of wood waste particles (WWP) is important for environmental and economic concern. This study focuses on the behavior mortars having WWP with various amounts. Incorporation brings about advantages such as decrease in mass cost mortar. In present study, proportions replacing crushed sand by volume were 0, 10, 20, 30 40 %. Physical, mechanical capillary absorption properties have been...

BACKGROUND Acute lower respiratory illnesses (ALRI) have been associated with exposure to domestic smoke. To examine further this association, a case-control study was conducted among Navajo children seen at the Public Health Service Indian Hospital at Fort Defiance, AZ. METHODS Cases, children hospitalized with an ALRI (n = 45), were ascertained from the inpatient logs during October, 1992, ...

Residential combustion has been identified as one of the main sources of particulate matter (PM); fine particles are important because of their adverse effects on human health and the environment. In this thesis, fine particle emissions originating from residential pellet combustion were characterized in different operational situations and using different raw materials as pellet fuel. Moreover...

Analyticity theorists, as I will call them, endorse the doctrine of analyticity in ontology : if some truth φ analytically entails the existence of certain things, then a theory that contains φ but does not claim that those things exist is no more ontologically parsimonious than a theory that also claims that they exist. Suppose, for instance, that the existence of a table in a certain location...

The human respiratory system is the gateway of entry for inhaled detritus from anthropogenic (e.g. combustionderived (CD) particulate matter (PM; e.g. diesel exhaust and wood-burning PM). Adult humans inhale 20m 3 of air and suspended debris (gases and particles) into the airways daily. Inhalation exposure to CDPM (Figure 1) is known to increase the risk of morbidity and mortality of lung and h...
