Using a combination of observations involving the Very Large Array (VLA), MERLIN and global Very Long Baseline Interferometry (VLBI) networks we have made a detailed study of the radio continuum and the neutral hydrogen (H I) kinematics and distribution within the central kiloparsec of the radio galaxy 3C 293. These observations trace the complex jet structure and identify the position of the s...

objective: scutellaria luteo-caerulea bornm. & snit. is one of the species of genus scutellaria, within the family of the lamiaceae, that is used for immune system stimulation and antibacterial effects in traditional medicine in iran. the aims of this study were to analyze essential oils and mineral element contents of leaves of  s. luteo-caerulea in flowering stage of development. materials an...

An optical absorption sensor for gas chromatography (GC) is presented. It consists of a quantum cascade laser along with a long piece of Hollow Waveguide for Infrared (HWIR) transmission inserted into the GC line. It measures the infrared absorption in each individual gas peak after separation by the GC column, and maintains the shapes of gas peaks after the HWIR sensor, making the gas samples ...

PURPOSE To present a physical model for intraocular absorption of an inert gas used as a tamponade. METHODS The absorption kinetics of gas in contact with the retinal surface is examined, including the changing geometry of the shrinking gas bubble inside the eye. RESULTS An analytic solution is derived that predicts how the bubble dimensions change with time, yielding a formula for the life...

We present a detailed analysis of narrow Na i and K i absorption resonance lines toward nearly 40 T Tauri stars in Taurus with the goal of clarifying their origin. The Na i 5889.95 Å line is detected toward all but one source, while the weaker K i 7698.96 Å line in about two thirds of the sample. The similarity in their peak centroids and the significant positive correlation between their equiv...

Onboard carbon capture and storage is an excellent solution to reduce the greenhouse gas emissions from shipping. This paper focuses on the absorption process and CO2 gas flow rate, the geometry of absorption tank and the concentration of absorption solution are key factors affecting the absorption efficiency. This paper will illustrate the experimental results of the impacts of these factors o...

Gas in scattering media absorption spectroscopy (GASMAS) has been extensively studied and applied during recent years in, e.g., food packaging, human sinus monitoring, gas diffusion studies, and pharmaceutical tablet characterization. The focus has been on the evaluation of the gas absorption pathlength in porous media, which a priori is unknown due to heavy light scattering. In this paper, thr...
