In advanced CHF and COPD, spiritual well-being remains stable over time, it varies by race and symptom distress, and contributes to quality of life, in combination with symptom distress, mental health and physical functioning.

[1] We present results of detailed paleomagnetic investigations on deep-sea cores from sediment drifts located along the Pacific continental margin of the Antarctic Peninsula. High-resolution magnetic measurements on u channel samples provide detailed age models for three cores collected from drift 7, which document an age of 122 ka for the oldest sediments recovered near the drift crest at site SED-07 and a high sedimentation rate (11 cm/kyr) at site SED-12 located close to the Alexander Channel system. Low-and high-temperature magnetic measurements in conjunction with microscopic and mineralogic observations from drifts 4, 5 and 7 indicate that pseudosingle-domain detrital titanomagnetite (partially oxidized and with limited Ti substitution) is the dominant magnetic mineral in the drift sediments. The titanomagnetite occurs in two magnetic forms: (1) a low-coercivity form similar to laboratory-synthesized titanomagnetite and (2) a high-coercivity form (B cr > 60 mT). These two forms vary in amount and stratigraphic distribution across the drifts. We did not find evidence for diagenetic magnetic iron sulfides as has been previously suggested for these drift deposits. The observed change of magnetic mineralogy in sediments deposited during Heinrich events on drift 7 appears to be related to warming periods, which temporarily modified the normal glacial transport pathways of glaciogenic detritus to and along the continental rise and thus resulted in deposition of sediments with a different provenance. Understanding this sediment provenance delivery signature at a wider spatial scale should provide information about ice sheet dynamics in West Antarctica over the last ∼100 kyr.

[1] This study constitutes the first attempt to integrate rock magnetism and metamorphic petrology in the Hercynian basement of northern Sardinia. The investigation focused on the magnetic petrology of variably retrogressed eclogites and amphibolites from two suites of basic meta-igneous rocks, which occur along a major tectonic line (Posada-Asinara Line), within a medium-grade (MG) and a high-grade (HG) metamorphic complex. Consistent with petromagnetic results, HG metabasites contain variable amounts of monoclinic pyrrhotite (intergrown with rutile) and titanomagnetite (occurring as inclusions in garnet), abundant ilmenite (associated to secondary hornblende and with sphene ± lowTi-magnetite rims), and rutile both as inclusions in ilmenite and as discrete grains. In MG metabasites, pyrrhotite is restricted to amphibolites of the Posada Valley area where it occurs as rare inclusions in garnet. All samples are characterized by variable amounts of ilmenite, rutile, and sphene which show the same microstructural features described in HG rocks. Microstructural evidence and geothermobarometric data indicate that (1) pyrrhotite and titanomagnetite likely formed prior to and remained stable during the eclogite facies metamorphic peak and (2) the growth of ilmenite and sphene can be attributed to the amphibolite facies retrogression, mainly due to model reactions such as garnet + omphacite + rutile + H 2 O ! hornblende + plagioclase + ilmenite and amphibole + ilmenite + O 2 ! sphene + magnetite + quartz + H 2 O. The results from our combined petrological and petromagnetic study corroborate the hypothesis that significant volumes of mafic/ultramafic rocks, similar to some of the investigated outcrops, may account for the magnetic anomalies flanking the northeastern part of the Posada-Asinara Line.
