Infrared Imaging of Hh 25/26 and Hh 42/128

چکیده
Images of the HH 25/26 and HH 42/128 systems obtained in the emission lines of H 2 1-0 S(1), Fe II] 1.64 m, and a 2.22 m continuum lter are reported. A series of aligned H 2 knots has been discovered in association with HH 26, along with a new infrared continuum source located at the center of a previously-discovered CO outtow which may power the HH 26 knots. HIRES images from IRAS are used to investigate the structure of deeply embedded sources near HH 25 and HH 26. The infrared structure of HH 42 is compared with that seen in visible S II] emission, and it is suggested that the HH 42/128 system has been produced by episodic outtows from a source located to the southwest of HH 42. Monochromatic 1.64], 2.12], and 2.22] mags are reported for stars detected in each eld, as well as H 2 and Fe II] emission-line uxes for HH knots in each system.

1514Targeting Behaviors Using Transtheoretical Model To Improve Hand Hygiene Adherence Among Intensive Care Unit Healthcare Workers
Background. To evaluate the behavioral-based interventions to improve hand hygiene (HH) among Thai intensive care units (ICUs) healthcare workers (HCW). Methods. A quasi-experimental study was performed at Thammasat University Hospital. Baseline HCW demographics, self-reported stage of HH behavior within the Trantheoretical Model (TTM), and observed HH adherence were examined. Pre-intervention ...
متن کاملGiant protostellar outflows revealed by infrared imaging
We present new infrared data from a survey for embedded protostellar jets in the Orion A cloud. This survey makes use of the S(1) v = 1–0 line of molecular hydrogen at λ = 2.12 μm to search for infrared jets deep inside the cloud and thus hidden from view at optical wavelengths. We present data on the three flows associated with the Herbig-Haro objects HH 43/38 & HH 64, HH 65, and the L1641-N g...
متن کاملI-3: Hypogonadotropic Hypogonadism
Hypogonadotropic hypogonadism (HH) is an uncommon cause of male infertility and a congenital or secondary disorder characterized by delayed or absent sexual maturation. Congenital abnormalities leading to HH are usually the consequence of deficient GnRH secretion occurring either in isolation (idiopathic hypogonadotropic hypogonadism (IHH)), or in association with anosmia (Kallmann syndrome; KS...
متن کاملWarm Molecular Hydrogen and Ionized Neon in the HH 2 Outflow
We report on spectro-imaging observations of the Herbig-Haro 2 outflow with the ISOCAM camera onboard the Infrared Space Observatory (ISO). The [Ne II] 12.81μm and [Ne III] 15.55μm lines are detected only towards the jet working surface (HH 2H), consistent with the high excitation of this knot in the optical range, while H2 pure rotational emission is found all over the shocked region HH 2. The...
