Basic Science and Risk Communication: A Dialogue-Based Study
The authors use ethnographic analysis of a focus group discussion between scientists and laypersons to study information exchange in risk communication
Plug flow and the breakdown of Bagnold scaling in cohesive granular flows
Cohesive granular media flowing down an inclined plane are studied by
discrete element simulations. Previous work on cohesionless granular media
demonstrated that within the steady flow regime where gravitational energy is
balanced by dissipation arising from intergrain forces, the velocity profile in
the flow direction scales with depth in a manner consistent with the
predictions of Bagnold. Here we demonstrate that this Bagnold scaling does not
hold for the analogous steady-flows in cohesive granular media. We develop a
generalization of the Bagnold constitutive relation to account for our
observation and speculate as to the underlying physical mechanisms responsible
for the different constitutive laws for cohesive and noncohesive granular
media.Comment: 8 pages, 10 figure

Apportionment of primary and secondary organic aerosols in Southern California during the 2005 Study of Organic Aerosols in Riverside (SOAR-1)
Ambient sampling was conducted in Riverside, California during the 2005 Study of Organic Aerosols in Riverside to characterize the composition and sources of organic aerosol using a variety of state-of-the-art instrumentation and source apportionment techniques. The secondary organic aerosol (SOA) mass is estimated by elemental carbon and carbon monoxide tracer methods, water soluble organic carbon content, chemical mass balance of organic molecular markers, and positive matrix factorization of high-resolution aerosol mass spectrometer data. Estimates obtained from each of these methods indicate that the organic fraction in ambient aerosol is overwhelmingly secondary in nature during a period of several weeks with moderate ozone concentrations and that SOA is the single largest component of PM1 aerosol in Riverside. Average SOA/OA contributions of 70−90% were observed during midday periods, whereas minimum SOA contributions of ~45% were observed during peak morning traffic periods. These results are contrary to previous estimates of SOA throughout the Los Angeles Basin which reported that, other than during severe photochemical smog episodes, SOA was lower than primary OA. Possible reasons for these differences are discussed
RANTES Secretion by Gene-Modified Tumor Cells Results in Loss of Tumorigenicity In Vivo: Role of Immune Cell Subpopulations
Overview summary Members of the chemokine superfamily mediate potent and selective chemoattraction of a variety of immune cell subsets, which is concentration dependent. This important and novel biologic activity raises the possibility of using chemokines as adjuvants in cancer vaccine strategies. We describe here the in vitro chemotactic capacity of RANTES for murine CD8+ tumor-infiltrating lymphocytes (TIL). Moreover, murine fibrosarcoma cells transfected with the cDNA encoding RANTES and secreting high levels of this chemokine become nontumorigenic in immunocompetent mice. The antitumor effect of RANTES is dependent on inherent tumor immunogenicity and is mediated through the participation of host-derived T cells and macrophages. Thus, the general chemoattractant properties exhibited by RANTES in vitro appear to be relevant in an in vivo model. These data warrant further investigation of other distinct members of the chemokine superfamily for their potential use, either alone or in combination, in gene therapy approaches that employ tumor cells as immunogens.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/63285/1/hum.1996.7.13-1545.pd
