House dust mites play an important role in the pathogenesis of allergic diseases. Many factors may influence mite growth. The presence of mites is related to mean temperature and humidity as well as altitude. The aim of this study was to analyze the mite fauna in 5 regions of western Anatolia, Turkey, that have similar climatic properties with low mean temperature and humidity, but differ in al...

This paper considers a simple model in which dust produced in a planetesimal belt migrates in toward the star due to P-R drag suffering destructive collisions with other dust grains on the way. Assuming the dust is all of the same size, the resulting surface density distribution can be derived analytically and depends only on the parameter η0 = 5000τeff (r0) √ M /r0/β; this parameter can be det...

We aim to constrain the dust mass and grain sizes in interaction regions between stellar winds ISM around asymptotic giant branch stars. By describing these regions, we shed light on role of low evolved stars origin galaxies. use images far-infrared at 70 micron 160 derive temperatures masses wind-ISM a sample carbon-rich oxygen-rich (AGB) The temperature are determined two ways. First directly...

We present spatially resolved mid-IR spectra of NGC 1068 with a diffractionlimited resolution of 0.25 using the Long Wavelength Spectrometer (LWS) at the Keck I telescope. The mid-infrared image of NGC 1068 is extended along the N-S direction. Previous imaging studies have shown the extended regions are located inside the ionization cones indicating that the mid-infrared emission arises perhaps...

We present 1.25mm continuum data for a southern galaxy sample selected from the IRAS PSC and complete to S60 = 2 Jy. Two thirds of the galaxies have been detected and significant limits on the remaining objects have been set. We find, on a statistical basis, indications that the dust emission in these galaxies is somewhat more centrally concentrated than that of the optical light, possibly trac...

Abstract. Even though desert dust is the most abundant aerosol by mass in Earth's atmosphere, relative contributions of world's major source regions to global cycle remain poorly constrained. This problem hinders accounting for potentially large impact regional differences properties on clouds, energy balance, and terrestrial marine biogeochemical cycles. Here, we constrain contribution each ma...

The nearby face-on spiral galaxy M101 has been observed with the Far-Infrared Surveyor (FIS) onboard AKARI. The far-infrared four-band images reveal fine spatial structures of M101, which include global spiral patterns, giant H II regions embedded in outer spiral arms, and a bar-like feature crossing the center. The spectral energy distribution of the whole galaxy shows the presence of the cold...
