Monitoring the concentration and distribution of nitrogen dioxide NO2 in urban environment is great interest because importance this gaseous pollutant affecting air quality. In paper we present development a multi-axis differential optical absorption spectroscopy instrument capable sensitively detecting NO2. The passive collects sun light scattered by molecules aerosols atmosphere measures spec...

Emerging evidence indicates that epidermal growth factor (EGF) signaling plays a positive role in myelin development and repair, but little is known about its biological effects on the early generation and differentiation of oligodendrocyte (OL) lineage cells. In this study, we investigated the role of EGF in early OL development with isolated glial restricted precursor (GRP) cells. It was foun...

Dissemination of Acinetobacter baumannii strains in different units of a hospital in Sorocaba, São Paulo, Brazil was evaluated over a period of two years. By using biotyping, serotyping and ribotyping, 27 distinct clones were differentiated among 76 strains isolated between 1993-94, from clinical specimens of hospitalized patients. Two clones, 2:O4:A (biotype:serotype:ribotype) and 2:O29:A acco...

Vibrio parahaemolyticus is recognized as major cause of foodborne illness of global public health concern. This study collected 107 strains of V. parahaemolyticus during active surveillance of diarrheal diseases in hospitals in Zhoushan during 2013 to 2014 and investigated their serotypes, virulence genes (tdh, trh, and orf8), antimicrobial resistance, and genotypes. The dominant serotypes of t...

Multi Axis Differential Absorption Spectroscopy (MAX-DOAS) is a well established measurement technique to derive atmospheric trace gas profiles by collecting scattered light spectra at different elevation angles and subsequent inverse modelling of the radiative transfer (Hönninger et al., 2004). Since aerosol particles are significantly involved in the scattering of the detected light, informat...

The type specimen of peisleyite has been reinvestigated by a combination of scanning electron microscopy, electron probe microanalysis (EPMA) and synchrotron powder X-ray diffraction. Morphological investigation showed that mats of peisleyite crystals, individually <3 mm across, are intergrown with wavellite veinlets to form the white cryptocrystalline material that is typical of ‘peisleyite’. ...

To identify and analyse precursor cells of neuronal and glial cell lineages during the early development of the chick peripheral nervous system, monoclonal antibodies were raised against a population of undifferentiated cells of E6 dorsal root ganglia (DRG). Non-neuronal cells of E6 DRG express surface antigens that are recognized by four monoclonal antibodies, G1, G2, GLI 1 and GLI 2. The prop...

Dideoxy chain-termination DNA sequencing was used to determine the specific DNA base changes induced after in vivo exposure of Escherichia coli to N-methyl-N-nitrosourea (MNU) and N-ethyl-N-nitrosourea (ENU) using the xanthine guanine phosphoribosyltransferase (gpt) gene as the genetic target. The resultant mutation spectra were compared with the levels of O6-alkylguanine and O4-alkylthymidine ...

Gravitational waves from binary neutron star mergers can be used as alerts to enable prompt follow-up observations. In particular, capturing electromagnetic and astroparticle emissions the moment of a merger presents unique constraints on time scale sky localization for online gravitational wave detection. Here we present expected performance SPIIR detection pipeline that is designed this purpo...
