801 Johnston, Susan S.Beginning augmentative communication systemsTo be unable to produce communicative behavior that can be understood by others represents one of the most frustrating experiences imaginable. Communicating through a communication board or with gestures lessens this frustration but does not eliminate it. Since 1975, remarkable advances have been ma...Intervention; Challenging behavior; Symbols1992
802 Miller, Jan D.The behavior of arsenic trioxide in non-ferrous extractive metallurgical processingStudy of the acid bake-leach process has shown potential advantages for the treatment of enargite (Cu3AsS4) concentrates. Among the most important advantages of the process is the transformation of enargite to water-soluble copper sulfate and highly soluble arsenic trioxide (arsenolite). Because ars...2014-01-01
803 Codding, BrianBehavioral ecology and the future of archaeological scienceThe future of archaeological science relies as much (if not more) on theoretical as on methodological developments. As with anything in biology, explaining past human behavior will require the application of evolutionary theory. As with anything in archaeology, theory is useless without clear ties t...2015-01-01
804 Yaffe, JoanneBehaviorism, social learning, and exchange theoryBehaviorism focuses on learning and the way in which behavior is shaped by its antecedent conditions and consequences. In rejecting mentalistic constructs such as mind, consciousness, and other internal processes, behaviorism stresses the importance of studying observable behavior rather than pheno...2006
805 Vardeny, Zeev ValentineBelow-gap excitation of ∏-conjugated polymer-fullerene blends: implications for bulk organic heterojunction solar cellsWe used a variety of optoelectronic techniques such as broadband fs transient and cw photomodulation spectroscopies, electroabsorption, and short-circuit photocurrent in bulk heterojunctions organic solar cells for studying the photophysics in ∏-conjugated polymer-fullerene blends with below-gap...pi-conjugated polymers; Fullerene blends; Below-gap excitations; Bulk heterojunctions; Bulk organic heterojunction solar cells; Photophysics2008-07
806 Pershing, David W.Bench and pilot scale process evaluation of reburning for in-furnace NOx reductionThis paper describes a combined experimental and theoretical study which was undertaken to quantify the impact of fuel and process parameters on reburning effectiveness and provide the scaling information required for commercial application of reburning under highly varied industrial conditions.

807 Miller, Jan D.Bench scale flotation of alunite ore with oleic acidAlunite [KA13(SO4)2(OH)6] is a promising non-bauxitic aluminum resource, the domestic reserves of which are estimated to be 800 x 106 tons at 35 percent alunite. The major gangue mineral associated with alunite is quartz. The thermochemical process that has been developed for treatment of this ore...Mesh; Separation; Liberation1980
808 Miller, Jan D.Bench scale flotation of sedimentary phosphate rock with hydroxamic acid collectorsIt has been discovered that water insoluble alcoholic solutions of alkyl hydroxamic acids serve as selective collectors for the flotation of phosphate mineral resources. The effectiveness of the new collector chemistry has been demonstrated by the results from single stage bench scale flotation exp...Flotation; Insoluble collectors; Hydroxamic acid; Alcohol; Phosphate rock; High solids conditioning; Particle size2002

810 Liu, FengBending of nanoscale thin Si film induced by growth of Ge islands: hut vs. domeWe perform atomistic simulations to compute bending of freestanding nanoscale thin Si film induced by strained Ge islands. We show that a larger Ge dome island can induce smaller bending than a smaller hut island and explain the surprising experimental observation for growth of Ge islands on pattern...Bending; Nanoscale thin Si film; Ge islands; Hut islands; Dome islands; Atomistic simulations2004
811 Liu, FengBending of nanoscale ultrathin substrates by growth of strained thin films and islandsMechanical bending is ubiquitous in heteroepitaxial growth of thin films where the strained growing film applies effectively an "external" stress to bend the substrate. Conventionally, when the deposited film is much thinner than the substrate, the bending increases linearly with increasing film th...Nanoscale ultrathin substrates; Strained thin films; Islands; Heteroepitaxial growth; Si substrate; Ge film2005-08
812 Goldberg, Robert A.Beneath the hood and robe: a socioeconomic analysis of Ku Klux Klan membership in Denver, Colorado, 1921-1925The Invisible Empire of the Knights of the Ku Klux Klan was in numbers and political influence the most powerful social movement of the 1920s and probably the most significant crusade of the American right-wing. Unlike its predecessor of the Reconstruction period or its descendant of today, this Kla...1980
813 Coley, Phyllis D.Beneficios y costos de defensa en un arbusto del neotrópicoLOS beneficios y costos son de importancia capital para las teorfas de optimization de las defensas de las plantas. El beneficio es la ganancia de aptitud para reducir el herbivorismo; el costo es la perdida de aptitud al comprometer recursos en defensa.

814 Hobson-Rohrer, Wendy L.Benefits and Barriers of Interprofessional Education Beyond the ClassroomMedical schools need to include interprofessional education (IPE) in their curricula not only to meet accreditation standards but to optimize students' readiness to practice in today's team-based heathcare environment. This is most often accomplished in classroom settings.Interprofessional Education; Team-Based Patient Cre; Collaboration2020
815 Coley, Phyllis D.Benefits and costs of defense in a neotropical shrubBenefits and costs are central to optimality theories of plant defense. Benefit is the gain in fitness to reducing herbivory and cost is the loss in fitness to committing resources to defense. We evaluate the benefits and costs of defense in a neotropical shrub, Psychotria horizontalis. Plants were ...Cost of defense; Growth-defense trade-off; Exclosures; Field experiment; Herbivory; Panama; Psychotria horizontalis; Rubiaceae; Tannins; Toughness; Tropics1995
816 Schmidt, Meic H.Benzoporphyrin derivative and light-emitting diode for use in photodynamic therapy: applications of space light-emitting diode technologyPhotodynamic therapy (PDT) is a cancer treatment modality that recently has been applied as adjuvant therapy for rain tumors. PDT consists of intravenously injecting a photosensitizer, which preferentially accumulates in tumor ells, into a patient and then activating the photosensitizer with a light...Benzoporphyrin; Photodynamic therapy; Brain tumors; Photofrin1998
817 Caserta, Michael; Lund, Dale A.Bereavement stress and coping among older adults: expectations versus the actual experienceThis investigation compared the stress and coping levels of 108 older adults who recently lost their spouse with expectations of stress and coping reported by eighty-five matched nonbereaved controls. While the bereaved reported moderately high stress levels over two years, their stress scores were ...Coping; Bereavement stress; Spousal bereavement1992

820 Chachas, MaryBetter resolutionThere's hardly anyone around today who is not familiar with the ultrasound image of a baby in the uterus. Usually it's confirmation that the fetus is all right, and the birth can be anticipated with joy. The skilled eye of a diagnostics expert, however, may detect something troubling.

823 Mallat, ChibliBeware of Sudan's Secessionist DemonsDemocracy means sorting out problems together, not going ones own way in a separate state every time there is disagreement. Only a miracle can save Sudan from the demons of secession. The precedent set could be devastating for the Middle East and well beyond.2010-09-02
824 Paiva, MarieBeyond databases: a creative approach in keeping up with our growing resourcesMost libraries in the 21st century provide databases for their users.
