An overview of the volcano-tectonic hazards of Portland, Oregon, and an assessment of emergency preparedness
(Massachusetts Institute of Technology, 2011)Portland, Oregon, lies within an active tectonic margin, which puts the city at risk to hazards from earthquakes and volcanic eruptions. The young Juan de Fuca microplate is subducting under North America, introducing not ... -
Oxygen isotope systematics of nitrification
(Massachusetts Institute of Technology, 2007)During nitrification there is an exchange of oxygen atoms between water and nitrite, causing the [delta]¹⁸O of nitrate produced by nitrification to be closer to the [delta]¹⁸O of water than expected. A series of lab and ... -
Oxygen precipitate studies in silicon for gettering in solar cell applications
(Massachusetts Institute of Technology, 2001)Oxygen precipitates in silicon can be used (in a process called internal gettering) as sites of heterogeneous nucleation of precipitates of iron and other transition metal that are harmful to solar cell device operation. ... -
Oxygen-oxygen bonds : catalytic redox pathways in energy storage
(Massachusetts Institute of Technology, 2009)Introduction: The present understanding of energy - its many forms, and its governing role in the time evolution of physical systems - underlies many of the most fundamental and unifying principles furnished by scientific ... -
Ozone chemistry during global glaciations : a possible climate feedback
(Massachusetts Institute of Technology, 2006)A theory for changes in ozone chemistry during late Proterozoic global glaciations is developed. The possible significance of temperature, humidity, nitrogen oxides, reactive chlorine, lightning frequency, surface deposition ... -
Packet delay and sequence number space in the radio link protocol layer
(Massachusetts Institute of Technology, 1998) -
Paleomagnetic Constraints on Assembly of the Superior Craton: Results from the 2.72-2.69 Ga Vermilion District of the Wawa Subprovince, MN
(Massachusetts Institute of Technology, 2022-05)Paleomagnetism can reveal ancient tectonic motions and identify the processes that regionally overprint magnetizations. We present paleomagnetic data from greenstones in the 2.72-2.69 Ga Vermillion Belt, Superior Craton, ... -
A paleomagnetic study of the angrite Sahara 99555
(Massachusetts Institute of Technology, 2009)Sahara 99555 (SAH 99555) is the oldest dated angrite sample, a rare type of meteorite, and is only ~2 Myr younger than the age of the solar system (1, 2). SAH 99555 shows no post-cooling brecciation or weathering from the ... -
Paleomagnetism conglomerate test on Archean conglomerate rock from Jack Hills, Australia
(Massachusetts Institute of Technology, 2011)A paleomagnetism study known as a conglomerate test was run on an Archean sandstone conglomerate rock to determine if the sample contained a remnant magnetization from the time of its formation. Twenty-nine clasts from a ... -
Paleomagnetism of Lonar impact glass
(Massachusetts Institute of Technology, 2008)Several dozen impact glasses from Lonar Crater, in Maharashtra, India, were analyzed for evidence of impact-generated paleofields, and possible motional remanent magnetization. Lonar Crater formed when a meteorite impacted ... -
Palladium-catalyzed C-N cross-coupling reactions toward the synthesis of drug-like molecules
(Massachusetts Institute of Technology, 2012)The development of methodologies for C-N bond formation reactions is an important scientific challenge because of many academic and industrial applications. This work will focus particularly on palladium-catalyzed ... -
Palmyra's ephemeral empire by Steven John Holcomb.
(Massachusetts Institute of Technology, 2016)The story of the third century AD rebellion of the Palmyrene Empire against the Roman Empire remains one of the most curious and fascinating episodes from the ancient world. Palmyra, a wealthy desert city-state, was neither ... -
