Observational diagnostics of gas in protoplanetary disks

Protoplanetary disks are composed primarily of gas (99% of the mass). Nevertheless, relatively few observational constraints exist for the gas in disks. In this review, I discuss several observational diagnostics in the UV, optical, near-IR, mid-IR, and (sub)-mm wavelengths that have been employed to study the gas in the disks of young stellar objects. I concentrate in diagnostics that probe the inner 20 AU of the disk, the region where planets are expected to form. I discuss the potential and limitations of each gas tracer and present prospects for future research.Comment: Review written for the proceedings of the conference "Origin and Evolution of Planets 2008", Ascona, Switzerland, June 29 - July 4, 2008.

Problems in interhospital pediatric intensive care transport in The Netherlands: results from a survey of general pediatricians

Problems in interhospital pediatric intensive care transport in The Netherlands: results from a survey of general pediatricians. Vos GD, Nieman FH, Meurs AM, Van Waardenburg DA, Ramsay G, Donckerwolcke RA. Department of Pediatrics, University Hospital Maastricht, P.O. Box 5800, 6202 AZ Maastricht, The Netherlands. [email protected] OBJECTIVE: Interhospital pediatric intensive care transport accompanied by non-trained specialists usually occurs with inadequate equipment and has been associated with high incidence of complications. These facts have serious consequences for patients but also can be very disconcerting for specialists. This survey was undertaken to gain insight into the problems encountered in organizing pediatric intensive care transport in The Netherlands to measure the specialist's satisfaction or dissatisfaction with the current state of affairs in the organization of such transports, and additional workload and feelings of insecurity experienced during self-organized transports. DESIGN: Survey, retrospective. SETTING: A postal questionnaire sent to all pediatricians of community hospitals in The Netherlands. METHODS: Results of direct questioning are given as discrete frequencies. After factor and reliability analysis 5-point Likert scale items are summed up in scale constructions. Relationships between scales are examined in regression analysis. RESULTS: Pediatricians appear to be satisfied with current specialist retrieval teams if these teams are available in their region, and highly dissatisfied if not available. Many nontrained specialists consider these transports burdening tasks with a high workload, and they feel insecure during these transports, especially if they report lack of knowledge of the transport equipment. CONCLUSIONS: The need for pediatric specialist retrieval teams in The Netherlands is seen not only in the insufficient level of care delivered by accompanying nontrained specialists and the reported high incidence of complications as shown in the literature but also in the dissatisfaction and high stress of these specialist

Interhospital paediatric intensive care transport: a novel transport unit based on a standard ambulance trolley

Interhospital paediatric intensive care transport: a novel transport unit based on a standard ambulance trolley. Vos GD, Buurman WA, van Waardenburg DA, Visser TP, Ramsay G, Donckerwolcke RA. Department of Pediatrics, University Hospital Maastricht, PO box 5800, 6202 AZ Maastricht, The Netherlands. [email protected] A recent development in providing intensive care for children is that it is more and more centralized in tertiary centres. The centralization of intensive care facilities for children in tertiary centres demands a safe and well-organized transport system. The transfer of critically ill children from a referring general hospital to a tertiary paediatric intensive care centre should be performed by a specially trained and fully equipped transport team. During the transfer of these children continuous intensive care facilities should be provided. The minimal requirements of equipment and materials for transport that allow such care have been determined. The equipment consists of a monitor allowing continuous measurement of vital signs, a defibrillator, tools for airway and ventilatory management, an oxygen source, suction unit, fluid and electrolyte management, medication, resuscitation chart and a communication system. A mobile paediatric intensive care unit was constructed in order to store this equipment, including easily accessible ventilator and materials optimized for close patient observation and ventilator contro
