951 Lighty, Joann; Sarofim, Adel F.Carbon dioxide effects on metal vaporization during coal combustionCoal combustion products may take one of two forms. Residual ash (> 1 micron) is formed by particle shrinkage and breaking during combustion. Some material will vaporize and later recondense. During recondensation, these molecules have a high affinity for submicron particles because of the large sur...Coal combustion products; Metal vaporization; Carbon dioxide; Residual ash2001
952 Ehleringer, James R.Carbon isotope discrimination and water relations of oak hybrid populations in southwestern UtahThe evergreen oak Quercus turbinella and the deciduous Q. gambelii form natural hybrids in southwestern Utah and northern Arizona. Hybrid individuals also are found in northern Utah in a region where only Q. gambelii currently exists, indicating that Q. turbinella has recently retreated southward. ...Quercus turbinella; Oak hybrids; Leaf structure; Leaf nitrogen; Carbon isotope discrimination; Water potential; Oak ecology2000
953 Ehleringer, James R.Carbon isotope discrimination in the C4 shrub Atriplex confertifolia along a salinity gradientCarbon isotope discrimination (∆) was measured for leaves of Atriplex confertifolia along a salinity gradi~ ent in northern Utah. Over this gradient, the variation of ∆ values was high for a C4 species, and the ∆ values were positively correlated with salinity in both years of the study. Of th...Carbon isotope ratio; Salt stress; Bundle sheath leakiness; Halophyte; Atriplex confertifolia; Salinity gradient1995
954 Ehleringer, James R.Carbon isotope dynamics in Abies amabilis stands in the CascadesCarbon isotope ratios (d13C) of canopy air and carbon isotope discrimination at the ecosystem level were studied in three montane Pacific silver fir (Abies amabilis (Dougl. ex Loud.) Dougl. ex J. Forbes) stands, an old-growth and two younger stands. Spatial and temporal variations of canopy CO2 con...Carbon isotopes; Pacific silver fir; Carbon budget; Soil respiration; Cascade Mountains1998
955 Ehleringer, James R.Carbon isotope ratios in belowground carbon cycle processesAnalyses of carbon isotope ratios (δ13C) in soil organic matter (SOM) and soil respired CO2 provide insights into dynamics of the carbon cycle. δ13C analyses do not provide direct measures of soil CO2 efflux rates but are useful as a constraint in carbon cycle models. In many cases, δ13C analyses...Below ground processes; Ecosystems; Carbon cycle; Carbon isotope ratio; Ecosystem processes; Global change; Soil organic carbon; Soil organic matter2000
956 Ehleringer, James R.Carbon isotope ratios of Atacama Desert plants reflect hyperaridity of region in northern ChileLeaf carbon isotope ratios were measured on plants from the coastal portions of the Atacama Desert at Pan de Azucar and Paposo, Chile. Most species possessed C3 photosynthesis, although there were several CAM species, indications of some facultative CAM species, and only one C4 species. The carbon i...Atacama Desert; Carbon isotope ratio; Intercellular carbon dioxide concentration; Hyperaridity1998
957 Orendt, Anita; Pugmire, Ronald J.Carbon-13 chemical shift tensors in polycyclic aromiatic compounds. 9. BiphenyleneThe principal values of the 13C chemical-shift tensors of natural abundance biphenylene were measured at room temperature with the FIREMAT experiment. Of 18 crystallographically distinct positions (three sets of six congruent carbons each), the three primary bands have been resolved into seven singl...Carbon-13; Chemical-shift tensors; Biphenylene; Polycyclic aromiatic compounds; FIREMAT2000
958 Digre, Kathleen B.; Blumenthal, Deborah T.; Cessna, Melissa H.; Gopez, Evelyn V.; Shen, YueCarcinomatous meningitis as the presenting manifestation of gallbladder carcinoma: case report and review of the literatureThe primary tumors that typically cause carcinomatous meningitis include lung cancer, breast cancer, leukemia, lymphoma and melanoma. A variety of neurological signs and symptoms can be seen depending on the extent and location of the meningeal metastasis. Once the diagnosis of carcinomatous meningi...Carcinomatous Meningitis; Gallbladder Carcinoma; Leptomeningeal Metastasis; Meningeal Carcinomatosis; Cranial Neuropathy2004-10

962 Diamond, LisaCareful what you ask for: reconsidering feminist epistemology and autobiographical narrative in research on sexual identity developmentFeminist theory has had an undoubtable but inconsistent influence on developmental psychology. Although feminist perspectives have productively challenged developmental models centered on male experiences (Gilligan 1982) and have called attention to socialization practices that reproduce systemati...Feminism; epistemology; autobiography2006
963 Llanque, Sarah M.Caregiver stress: a concept analysisThe purpose of this concept analysis is to provide clarity on the concept of caregiver stress as it pertains to the caregiver of people with Alzheimer's disease and related dementias.2014-01-01
964 Wright, Scott D.Caring to cultivate on the long row of life: an eclectic look at gardens, gardening, and the aging processGardening is one of the most popular home-based leisure activities in the U.S. and represents an important activity in the lives of older adults in a variety of residential settings. Yet, there has been a lack of any comprehensive and multidisciplinary examination of the nexus between gardening and...gardening; gardens; aging; caring2010
965 Silverman, Randall H.Carol Twombly on typeThe appeal of an inviting building begins with its solid architectural space. So too with typography, that all-too-often unnoticed "architecture" implicit in the conveyance of the printed word. Viewed under magnification, bold, vertical stems clearly support cross bars like studs; spherical bowls op...Typography; Type designer; Typeface1994
966 Couldwell, William T.; Orlandi, Richard R.Carotid artery-sparing repair of a cavernous carotid artery pseudoaneurysmCarotid artery (CA) injury after transsphenoidal and endoscopic sinus surgery is a well-recognized but fortunately rare complication.1 It is associated with significant morbidity and mortality rates5 and is more common in cases of repeated surgery, cavernous sinus invasion, prior radiotherapy, and ...Carotid artery; Sinus; Pseudoaneurysm; Endoscopic surgery2006

970 Battin, Margaret P.Case comment: the case of Nicole: suicide and terminal illnessWhat shall one say about Nicole? My immediate answer is an easy one-liner: if there ever were a case in which a choice of suicide appears both rational and rationally made, this seems to be it.1933

973 Riloff, Ellen M.Case study in using linguistic phrases for text categorization on the WWWMost learning algorithms that arc applied to text categorization problems rely on a bag-of-words document representation, i.e., each word occurring in the document is considered as a separate feature.
