A 44-yr climatology of spring Asian dust aerosol emission, column loading, deposition, trans-Pacific transport routes, and budgets during 1960–2003 was simulated with the Northern Aerosol Regional Climate Model (NARCM). Interannual variability in these Asian dust aerosol properties simulated by the model and its climate connections are analyzed with major climatic indices and records in ground ...

An increase in the number of motorized vehicles has potential to air pollution, es-pecially on protocol roads, one which is Particulate matter (PM 2.5). The response tri-chomes from shade plants vehicle exhaust gases can be used as environmental biomonitor-ing. main road Seberang Ulu II District a fairly dense mobility terms Ve-hicle Volume Ratio Road Capacity (VCR). purpose this study was dete...

A Spitzer Space Telescope survey in the NOAO Deep-Wide Field in Boötes provides a complete, 8 μm-selected sample of galaxies to a limiting (Vega) magnitude of 13.5. In the 6.88 deg field sampled, 79% of the 4867 galaxies have spectroscopic redshifts, allowing an accurate determination of the local (z < 0.3) galaxy luminosity function. Stellar and dust emission can be separated on the basis of o...

The street garment vendors are playing a significant role in the fields of the economic development through protecting resources (garment products) from such a position where they are treated as wastes; very much less valued products and creating the opportunity for self-employment. This study aimed at showing the economic contribution and the impact of the street vendors to the local community...

Introduction: Children, who work or live at streets, are one of the HIV high risk groups in Iran, with no comprehensive preventive programs. This study intended to assess substance use among street children in Tehran, Capital of Iran. Methods: This paper is a part of comprehensive rapid assessment and response (RAR) research on street children in Tehran i...

introduction thermal infrared integrated dust index (tiidi) is one of indices that is presented in this direction. the index operates based on four brightness temperature difference including wavelengths 3.7, 8.6, 11 and 12 micrometer. according to the studies, btd (bt12-bt11) is used for cloud detection. btd (bt8.6-bt11) is the index for separation for dust from sandy surface and btd (bt3.7-bt...

Abstract Background Occupational predisposition to dry eye disease is known. Simultaneous exposure multiple factors may pose more risk. Street sweepers are exposed sunlight in addition dust which all to. Tropical climate predisposes significant sunlight. Combined and lead a synergy of factors. This study aims assess the prevalence (DED) amongst Office cleaners Calabar metropolis. Methods A cros...

The deformation of underground gateroads tends to be asymmetric and complex. Traditional instrumentation fails to accurately and conveniently monitor the full cross-sectional deformation of underground gateroads. Here, a full cross-sectional laser scanner was developed, together with a visualization software package. The developed system used a polar coordinate measuring method and the full cro...
