An infrared-submillimeter study of star-forming regions selected by the ISOSS 170um survey

open access: yes, 2008
Using the ISOPHOT Serendipity Survey (ISOSS) at 170um a sample of galactic star-forming regions exhibiting very cold dust temperatures (< 20 K) and high masses (> 100 M_sun) has been established.

A spectroscopic examination of accretion diagnostics for near solar mass stars in IC 348 [PDF]

open access: yes, 2008
High-resolution optical and moderate-resolution near-infrared spectra were obtained for 40 near solar mass (~2.0-0.5 M⊙) members of the 2-3 Myr old cluster IC 348 in order to examine established accretion diagnostics and the coupling between inner disk ...

INFRARED SPECTROPHOTOMETRY, A RAPID AND EFFECTIVE TOOL FOR CHARACTERIZATION OF DIRECT DISTILLATION NAPHTHAS La espectrofotometría infraroja, una herramienta rápida y efectiva para la caracterización de naftas de destilación directa

open access: yesCT&F Ciencia, Tecnología & Futuro, 2005
The characterization of naphtha obtained by direct distillation of medium and heavy crude oils is often limited by the low yield of these fractions. Gas chromatography is a technique that allows a complete determination of the chemical composition of ...

Simulated Extragalactic Observations with a Cryogenic Imaging Spectrophotometer [PDF]

open access: yes, 2000
In this paper we explore the application of cryogenic imaging spectrophotometers. Prototypes of this new class of detector, such as superconducting tunnel junctions (STJs) and transition edge sensors (TESs), currently deliver low resolution imaging ...

Investigation of in vivo measurement of cerebral cytochrome-c-oxidase redox changes using near-infrared spectroscopy in patients with orthostatic hypotension [PDF]

open access: yes, 2007
We have previously used a continuous four wavelength near infrared spectrometer to measure changes in the cerebral concentrations of oxy- (Δ[HbO2] and deoxy- haemoglobin (Δ[HHb]) during head-up tilt in patients with primary autonomic failure.

Preparation of Polyester-Based Metal-Cross Linked Polymeric Composites as Novel Materials Resistant to Bacterial Adhesion and Biofilm Formation

open access: yesMolecules, 2011
Bacterial biofilms constitute an extremely resistant form of bacterial colonization with dire health and economical implications. Towards achieving polymeric composites capable of resisting bacterial adhesion and biofilm formation, we prepared five 2,6 ...
