The dynamical states of molecular clouds may affect the properties stars they form. In vicinity Trifid Nebula ($d=1180\pm25$ pc), main star cluster (Trifid Main) lies within an expanding section cloud; however, ~0.3 deg to north North), cloud's velocity structure is more tranquil. We acquired a Chandra X-ray observation identify pre-main-sequence in North, complementing previous Main. we identi...

The goal of this paper was to assess the possibilities for one-stage reactor anaerobic digestion processing fruit and vegetable biomass within a biorefinery concept optimum products. Co-digestion simplest strategy implement increase product yield among variables tested (pH, ultrasonification, co-digestion). Methane yields from co-digestion waste (FVW) pig manure (PM) ranged 318 434 NmL /g VS, w...

The $UBVRI$ CCD photometric data of open star cluster NGC 1513 are obtained with the 3.6-m Indo-Belgian Devasthal optical telescope (DOT). Analyses GAIA EDR3 astrometric have identified 106 possible members. mean proper motion is estimated as $\mu_{\alpha}Cos{\delta}=1.29\pm0.02$ and $\mu_{\delta}=-3.74\pm0.02$ mas yr$^{-1}$. Estimated values reddening $E(B-V)$ distance to 0.65$\pm$0.03 mag 1.3...

association between [chronic PM] air pollution exposure and health [mortality]." In applying these criteria, I have included experimental studies in animals and epi-demiologic studies in humans (6). Rodents exposed to high concentrations of diesel exhaust for life did not show early or increased mortality (6). The available epi-demiologic studies (3-5) showed only weak associations across a nar...

the ability of subminimum inhibitory concentrations (sub-mics) of antibiotics to affect the virulence factors of bacteria may be an important criterion in selecting an antibiotic for therapy. proteus mirabilis is one of the most frequently seen pathogens in urinary tract infections. the aim of this study was to analyze the effects of some antibiotics on two important virulence factors of p. mir...

OBJECTIVES This study was conducted to assess the size characteristics of particulate matter (PM) generated during waste collection and sorting, and to assess the effect of the type of waste-handling activity on levels of coarse and fine PM. METHODS A portable aerosol spectrometer calibrated to 1.2 //min was used to monitor PM generated during four types of waste-handling activities. The type...

With increasing evidence of adverse health effects associated with particulate matter (PM), the exposure impact of natural sources, such as forest fires, has substantial public health relevance. In addition to the threat to nearby communities, pollutants released from forest fires can travel thousands of kilometers to heavily populated urban areas. There was a dramatic increase in forest fire a...

Scientific assessments of agricultural air quality, including estimates of emissions and potential sequestration of greenhouse gases, are an important emerging area of environmental science that offers significant challenges to policy and regulatory authorities. Improvements are needed in measurements, modeling, emission controls, and farm operation management. Controlling emissions of gases an...

the photocatalytic decomposition of trichloroethylene (tce) and tetrachloroethylene (pce)in water was studied. tce and pce were present in water at very low concentrations of about 15 μg/dm3. thisconcentration level corresponds to the one occasionally occurring in groundwater. results of this researchconfirmed usefulness of the photocatalytic process for successful removal of low-concentrated t...

the effects of three arbuscular mycorrhizal fungi (amf) species (glomus versiforme, claroideoglomus etunicatum and rhizophagus intraradices) were studied on the growth parameters and nutrient uptake of three apple rootstocks (m.9, m.7 and mm.106). the soil medium contained a high level of calcium carbonate (38.65%). the results showed that amf inoculation could increase almost all growth parame...
