Discovery of the most luminous quasar of the last 9 Gyr
We report the discovery of a bright (g = 14.5 mag (AB), K = 11.9 mag (Vega))
quasar at redshift z = 0.83 -- the optically brightest (unbeamed) quasar at z >
0.4. SMSS J114447.77-430859.3, at a Galactic latitude of b = +18.1deg, was
identified by its optical colours from the SkyMapper Southern Survey (SMSS)
during a search for symbiotic binary stars. Optical and near-infrared
spectroscopy reveals broad MgII, H-beta, H-alpha, and Pa-beta emission lines,
from which we measure a black hole mass of log10(M_BH/M_Sun) = 9.4 +/- 0.5.
With its high luminosity, L_bol = (4.7 +/- 1.0) * 10^47 erg/s or M_i(z=2) =
-29.74 mag (AB), we estimate an Eddington ratio of ~1.4. As the most luminous
quasar known over the last ~9 Gyr of cosmic history, having a luminosity 8
times greater than 3C 273, the source offers a range of potential follow-up
opportunities.Comment: 13 pages. Accepted for publication in PAS
Nurse's support to family members : A study on family memberâs experiences of support within the intensive care unit.
UppmÀrksamhet och stöd till intensivvÄrdspatienters anhöriga kan ibland bli begrÀnsad dÄ sjuksköterskan ofta fokuserar pÄ patientens behov och glömmer bort de anhöriga. Eftersom möten med anhöriga sker frekvent inom sjuksköterskeyrket Àr det dÀrför viktigt att sjuksköterskan har insikt och förstÄelse för vad anhöriga upplever som stödjande. PÄ en intensivvÄrdsavdelning Àr tillstÄndet hos patienten ofta kritiskt och de anhöriga behöver stöd för att hantera, förstÄ och anpassa sig till situationen. Syftet med den strukturerade litteraturstudien Àr att belysa anhörigas upplevelser av sjuksköterskans stöd inom intensivvÄrd. Sammanlagt har 10 vetenskapliga artiklar sÄvÀl med kvalitativ och kvantitativ ansats analyserats tematiskt och analysen gav fyra kategorier, Tillit och förtroende, NÀrvaro och delaktighet, Tröst och empati samt TillgÀnglighet och kontinuitet. Sammanfattningsvis finns det ett stort behov av att fÄ stöd som anhörig. De anhöriga Àr i allmÀnhet nöjda med stödet de fÄr av sjuksköterskan inom intensivvÄrden men det behövs ytterligare forskning om vad för stöd som behövs samt hur stödet upplevs av de anhöriga.The attention and support given to family members at the Intensive Care Unit can sometimes be limited due to that the nurses often focus on the patient's needs and forget about family members needs. Since nurses meet family members on a daily basis it is important for them to know what family members find supportive. The condition of patients at the intensive care unit is often critical and family members need support to cope, understand and adapt to the situation. The aim of the study was to highlight family membersŽ experiences of support from nurses at the intensive care unit. A structured literature review was conducted in which 10 articles with both qualitative and quantitative design underwent thematic analysis. The analysis gave four categories: Trust and reliance, Presence and participation, Comfort and empathy and Availability and continuity. To sum up; family members at the Intensive Care Unit have a great need of support. Family members are in general satisfied with the support, but there is need for more research in what kind of support they require and how family members experience the support
