Strong Earthquake Motion Estimates for Three Sites on the U.C. Riverside Campus  

SciTech Connect

The approach of the Campus Earthquake Program (CEP) is to combine the substantial expertise that exists within the UC system in geology, seismology, and geotechnical engineering, to estimate the earthquake strong motion exposure of UC facilities. These estimates draw upon recent advances in hazard assessment, seismic wave propagation modeling in rocks and soils, and dynamic soil testing. The UC campuses currently chosen for application of our integrated methodology are Riverside, San Diego, and Santa Barbara. The procedure starts with the identification of possible earthquake sources in the region and the determination of the most critical fault(s) related to earthquake exposure of the campus. Combined geological, geophysical, and geotechnical studies are then conducted to characterize each campus with specific focus on the location of particular target buildings of special interest to the campus administrators. We drill and geophysically log deep boreholes next to the target structure, to provide direct in-situ measurements of subsurface material properties, and to install uphole and downhole 3-component seismic sensors capable of recording both weak and strong motions. The boreholes provide access below the soil layers, to deeper materials that have relatively high seismic shear-wave velocities. Analyses of conjugate downhole and uphole records provide a basis for optimizing the representation of the low-strain response of the sites. Earthquake rupture scenarios of identified causative faults are combined with the earthquake records and with nonlinear soil models to provide site-specific estimates of strong motions at the selected target locations. The predicted ground motions are shared with the UC consultants, so that they can be used as input to the dynamic analysis of the buildings. Thus, for each campus targeted by the CEP project, the strong motion studies consist of two phases, Phase 1--initial source and site characterization, drilling, geophysical logging, installation of the seismic station, and initial seismic monitoring, and Phase 2--extended seismic monitoring, dynamic soil testing, calculation of estimated site-specific earthquake strong motions at depth and at the surface, and, where applicable, estimation of the response of selected buildings to the CEP-estimated strong motions.

Famous physicians-botanists.  

PubMed

Two hundred years ago a group of physicians laid the foundations of botany with their study of plants for medicinal purposes. Linnaeus of Sweden devised the binomial classification of plants, which is still in use today. Boerhaave of Leyden revitalized bedside teaching and was a major influence in the English-speaking medical schools. Sloane founded the still-existing Physic Garden in London; his natural history collection formed the foundation of the British Museum. Withering prepared digitalis from the purple foxglove and wrote a standard work on the cultivation of vegetables. The gardenia and poinsettia are named after New World physician-botanists Alexander Garden and Joel Poinsett. Swedish physicians Sparrman and Thunberg, pupils of Linnaeus, were the major and original describers of the Cape flora. Atherstone of Grahamstown--the first doctor to use a general anaesthetic (ether) outside America and Europe--is a 19th century example of the naturalist physician as an ardent botanist; he was also a geologist and identified the first diamond found in South Africa.

Joseph Hooker: the making of a botanist.  

PubMed

Joseph Hooker became one of the most influential botanists of his day. He is best remembered as a friend of Charles Darwin and an early advocate of natural selection. However, after returning to Britain from his first major voyage, Hooker spent years struggling to find a paid position that would allow him to pursue his studies of plant classification and distribution. As he worked to establish himself, he also helped transform the status of botany as a discipline. In all his efforts, Hooker relied on a network of unpaid, colonial collectors, whose often-forgotten contributions to Victorian natural history are vital to the understanding of the professionalization of the sciences in the 19th century.

Fogwater chemistry at Riverside, California  

NASA Astrophysics Data System (ADS)

Fog, aerosol, and gas samples were collected during the winter of 1986 at Riverside, California. The dominant components of the aerosol were NH 4+, NO 3-, and SO 42-. Gaseous NH 3 was frequently present at levels equal to or exceeding the aerosol NH 4+. Maximum level were 3800, 3100, 690 and 4540 neq m -3 for NH 4+, NO 32- and NH 3(g), respectively. The fogwater collected at Riverside had very high concentrations, particularly of the major aerosol components. Maximum concentrations were 26,000 29,000 and 6200 ?M for NH 4+, NO 3- and SO 42-, respectively. pH values in fogwater ranged from 2.3 to 5.7. Formate and acetate concentrations as high as 1500 and 580 ?M, respectively, were measured. The maximum CH 2O concentration was 380 ?M. Glyoxal and methylglyoxal were found in all the samples; their maximum concentrations were 280 and 120 ?M, respectively. Comparison of fogwater and aerosol concentrations indicates that scavenging of precursor aerosol by fog droplets under the conditions at Riverside is less than 100% efficient. The chemistry at Riverside is controlled by the balance between HNO 3 production from NO x emitted throughout the Los Angeles basin and NH 3 emitted from dairy cattle feedlots just west of Riverside. The balance is controlled by local mixing. Acid fogs result at Riverside when drainage flows from the surrounding mountains isolate the site from the NH 3 source. Continued formation of HNO 3(g) in this air mass eventually depletes the residual NH 3(g). A simple box model that includes deposition, fog scavenging, and dilution is used to assess the effect of curtailing the dairy cattle feedlot operations. The calculations suggest that the resulting reduction of NH 3 levels would decrease the total NO 3- in the atmosphere, but nearly all remaining NO 3- would exist as HNO 3. Fogwater in the basin would be uniformly acidic.

Initial source and site characterization studies for the U.C. Santa Barbara campus  

SciTech Connect

The University of California Campus-Laboratory Collaboration (CLC) project is an integrated 3 year effort involving Lawrence Livermore National Laboratory (LLNL) and four UC campuses - Los Angeles (UCLA), Riverside (UCR), Santa Barbara (UCSB), and San Diego (UCSD) - plus additional collaborators at San Diego State University (SDSU), at Los Alamos National Laboratory and in industry. The primary purpose of the project is to estimate potential ground motions from large earthquakes and to predict site-specific ground motions for one critical structure on each campus. This project thus combines the disciplines of geology, seismology, geodesy, soil dynamics, and earthquake engineering into a fully integrated approach. Once completed, the CLC project will provide a template to evaluate other buildings at each of the four UC campuses, as well as provide a methodology for evaluating seismic hazards at other critical sites in California, including other UC locations at risk from large earthquakes. Another important objective of the CLC project is the education of students and other professional in the application of this integrated, multidisciplinary, state-of-the-art approach to the assessment of earthquake hazard. For each campus targeted by the CLC project, the seismic hazard study will consist of four phases: Phase I - Initial source and site characterization, Phase II - Drilling, logging, seismic monitoring, and laboratory dynamic soil testing, Phase III - Modeling of predicted site-specific earthquake ground motions, and Phase IV - Calculations of 3D building response. This report cover Phase I for the UCSB campus and incudes results up through March 1997.

Detection of Reactive Ions Towards UC H  

NASA Astrophysics Data System (ADS)

We report the first detection of the reactive ions CO+ and HOC+ towards ultracompact (UC) Hii regions, in particular Mon R2 and G29.96-0.02. Two positions in Mon R2, the peak of the UC Hii region and a position in the high density molecular cloud which bounds it, were observed. CO+ and HOC+ were detected at the UC Hii region but not in the molecular cloud, as expected if the CO+ and HOC+ emissions arise in the PDR surrounding the UC Hii region. The measured CO+ and HOC+ column densities are of order of ? 1011 cm 2 in both sources, which yields a strikingly low [HCO+]/[HOC+] abundance ratio of 460 in Mon R2. Our values are similar to those found in some other well-known PDRs, like NGC 7023 or the Orion Bar.

Being a botanist and a gardener: using diagnostic frameworks in general practice patients with medically unexplained symptoms.  

PubMed

Patients with multiple medically unexplained symptoms commonly seek treatment in primary care. Many of these patients seem to have a psychological 'core' to their illness that affects the way they experience, conceptualise and communicate their distress. There is considerable debate around diagnosis for this group of patients. Existing diagnoses include somatoform disorders in psychiatry and functional disorders in the medical specialties. Some clinicians use the term 'heartsink' patients, which reflects the interpersonal frustration inherent in some therapeutic relationships. A good diagnosis should be clinically useful, helping clinicians and patients understand and manage illness. Diagnosis should also provide a reliable classification for research and evidence-based treatment. The allegory of the botanist and the gardener has been used to describe diagnosis. For the botanist, a good diagnosis produces a taxonomy that is rigorous and reliable. For the gardener, it informs the way a garden is described and understood in a specific context. Clinicians need both: a 'botanical' type of classification to bring rigour to research and therapy, and clinical 'gardening', which allows for multiple perspectives and diagnostic frameworks. Clinical reasoning is a form of research with therapeutic intent. Botany and gardening represent a mixed-methods approach that can enrich diagnosis. The challenge is to integrate multiple perspectives in clinically helpful ways that help us retain both richness and rigour. PMID:22951035

The journal Broteria has covered a long path, since its foundation in 1902 until the mid 20's, when it stands as one of the best journals of natural history and a voice of the renewal of the natural sciences in Portugal. Broteria's success was due, mainly, to the remarkable qualities of its founders and main editors: their working capacity, intellectual standards and perseverance as well as the ability to establish a network of naturalists who sent them biological collections from remote regions and the ability to adapt to exile, while continuing to work and focusing their studies on the natural history of the exile country. The maintenance, in regular functioning, of their schools, and the opening to the collaboration of non Jesuit naturalists, such as the botanists from Oporto, also contributed to the success of Broteria.

[Carcinogenic risk in residents of the Techa riverside villages].  

PubMed

The paper summarizes carcinogenic risk estimates in residents of the Techa riverside villages who have been exposed for many years to radiation due to discharge of radioactive wastes from the Mayak Production Association into the Techa-Iset-Tobol-Ob river system. Analysis of cancer incidence and mortality data has shown a statistically significant dose-dependent increase in the risk of both malignant tumors and leukemia. The dependence of excess relative risk on exposure dose is well described by a linear model. No evidence has been obtained that carcinogenic risk resulting from low-rate radiation exposure is lower than that from acute exposure of A-bomb survivors. Difficulties of following up vital status due to population migration, incomplete data on mortality causes, and inaccurate dose estimates are believed to be key contributors to radiation risk uncertainties.

This paper examines the crucial early history of the American Journal of Botany from the years following the founding of the Botanical Society of America in 1906 to the termination of the agreement for publication with the Brooklyn Botanic Garden in 1935. It examines the efforts of individuals like F. C. Newcombe, who did the most to raise support for the journal and became the first Editor-in-Chief, in the context of the growing numbers of professional botanists and plant scientists who were actively engaged in research requiring appropriate publication venues and in the process of forming an independent identity as "American botanists." It also examines the launching of the journal in the context of the Great War in Europe and the transition from German botany to American botany in the second decade of the 20th century.

Mercury pollution and childhood in Amazon riverside villages.  

PubMed

Mercury is a hazardous metal responsible for environmental contamination and human intoxication. Methylmercury, a very toxic organic compound, bio-accumulates through food chain, and is responsible for chronic mercury exposure of riverside Amazonian communities with a diet rich in fish. Uncertainties about the reference exposure dose that could have damaging consequences for nervous system development makes necessary the biomonitoring of these Amazonian populations, especially children. In this work, a comparative study was performed in exposed and non-exposed children living in the Amazon. A total of 168 children were analyzed to find possible correlations between gender, age, location, and hair mercury content. For each location, no statistically significant differences (P<0.05) were detected for gender and age versus mercury content. However, mean mercury levels in hair samples may indicate a tendency of boys to average higher hair concentrations. Also, in the community with highest levels of mercury, the limit of 10 micro g/g of mercury was surpassed by 65% of 2-6 years and 50% of 7-12 years children but only by 27% of 0-1 year babies, pointing to a lower bioaccumulation and/or the existence of a protection mechanism in babies. Log normal distributions of mercury concentrations for each location showed that children from populations under influence of gold mining activity contain the highest mercury levels in hair samples, though this intoxication may have decreased when compared to previous studies. Knowledge originated by this monitoring will better assist in the development of prevention strategies and government actions targeting the mercury contamination of Amazonian environment.

Diurnal and Seasonal Variability of Gasoline-Related Volatile Organic Compounds in Riverside, CA  

NASA Astrophysics Data System (ADS)

On and off-road mobile source emissions are the dominant contributor to urban anthropogenic volatile organic compound (AVOC) emissions. Analyses of speciated gasoline samples from California for both summer and winter indicate significant differences in chemical composition due to intentional seasonal adjustments to liquid fuel composition. Ambient air measurements of ~60 compounds, including VOCs, were measured via in-situ gas chromatography during the Study of Organic Aerosols at Riverside (SOAR) 2005 for both summer and fall. A chemical mass balance analysis was used to differentiate evaporative and tailpipe VOC emissions from motor vehicles. Overall, evaporative emissions accounted for 31 ± 2% of gasoline emissions in Riverside, CA. The California Air Resources Board (CARB) EMFAC model similarly estimates 39% of gasoline engine-related VOC emissions are due to evaporative sources for Riverside County. Diurnal evaporative emission source contributions are relatively stable around 10 ug/m3, while tailpipe emissions peak at ~60 ug/m3 during the morning commuter peak period and lack a peak in emissions during the afternoon commute due to rapid dilution associated with high afternoon vertical mixing heights and wind speeds in the Riverside area. The relative increases in ambient VOC and carbon monoxide concentrations during pollution events are consistent with CARB's 2005 emission inventory; we calculated 0.086 ± 0.006 mass of VOC emissions to mass of CO emissions compared to 0.105 in the emission inventory.

Recent Results from the uc(ANTARES) Neutrino Telescope  

NASA Astrophysics Data System (ADS)

The uc(ANTARES) detector, located 40 km off the French coast, is the largest deep-sea neutrino telescope in the world. It consists of an array of 885 photomultipliers detecting the Cherenkov light induced by charged leptons produced by neutrino interactions in and around the detector. The primary goal of uc(ANTARES) is to search for astrophysical neutrinos in the TeV-PeV range. This comprises generic searches for any diffuse cosmic neutrino flux as well as more specific searches for astrophysical sources such as active galactic nuclei or galactic sources. The search program also includes multi-messenger analyses based on time and/or space coincidences with other cosmic probes. The uc(ANTARES) observatory is sensitive to a wide range of other phenomena, from atmospheric neutrino oscillations to dark matter annihilation or potential exotics such as nuclearites and magnetic monopoles. The most recent results are reported.

Calculation of elastic constants in UC, US, and UTe  

NASA Astrophysics Data System (ADS)

The calculated electronic structure and charge density of UC and US are reported. We also report calculations on the elastic constants of the cubic compounds UC, US, and UTe using the local-spin-density approximation (LSDA) to the exchange and correlation potential. Good agreement between calculations and experiment has been obtained for UC and US suggesting that the chemical bonding is well reproduced by LSDA for these two compounds. In contrast, for UTe the calculations do not reproduce the measured negative Poissons ratio (negative C12). We suggest that the failure to describe the elasticity of UTe reflects the weakness of LSDA in describing accurately electron systems that are strongly correlated and we speculate that UTe is an anomalous, possibly mixed valent, system.

Airborne radioactivity surveys in the Mojave Desert region, Kern, Riverside, and San Bernardino Counties, California  

USGS Publications Warehouse

Airborne radioactivity surveys in the Mojave Desert region Kern, Riverside, and Bernardino counties were made in five areas recommended as favorable for the occurrence of radioactive raw materials: (1) Rock Corral area, San Bernardino County. (2) Searles Station area, Kern county. (3) Soledad area, Kern County. (4) White Tank area, Riverside and San Bernardino counties. (5) Harvard Hills area, San Bernardino County. Anomalous radiation was detected in all but the Harvard Hills area. The radioactivity anomalies detected in the Rock Corral area are of the greatest amplitude yet recorded by the airborne equipment over natural sources. The activity is apparently attributable to the thorium-beating mineral associated with roof pendants of crystalline metamorphic rocks in a granitic intrusive. In the Searles Station, Soledad, and White Tank area, several radioactivity anomalies of medium amplitude were recorded, suggesting possible local concentrations of radioactive minerals.

Reconstruction of Long-Lived Radionuclide Intakes for Techa Riverside Residents: Cesium-137  

SciTech Connect

Radioactive contamination of the Techa River (Southern Urals, Russia) occurred from 1949–1956 due to routine and accidental releases of liquid radioactive wastes from the Mayak Production Association. The long-lived radionuclides in the releases were 90Sr and 137Cs. Contamination of the components of the Techa River system resulted in chronic external and internal exposure of about 30,000 residents of riverside villages. Data on radionuclide intake with diet are used to estimate internal dose in the Techa River Dosimetry System (TRDS), which was elaborated for the assessment of radiogenic risk for Techa Riverside residents. The 90Sri ntake function was recently improved taking into account the recently available archival data on radionuclide releases and in-depth analysis of the extensive data on 90Sr measurements in Techa Riverside residents. The main purpose of this paper is to evaluate the dietary intake of 137Cs by Techa Riverside residents. The 137Cs intake with river water used for drinking was reconstructed on the basis of the 90Sr intake-function and the concentration ratio 137Cs/90Sr in river water. Intake via 137Cs transfer from floodplain soil to grass and cows’ milk was evaluated for the first time. As a result, the maximal 137Cs intake level was indicated near the site of releases in upper-Techa River settlements (8,000–9,000 kBq). For villages located on the lower Techa River the 137Cs intake was significantly less (down to 300 kBq). Cows’ milk was the main source of 137Cs in diet in the upper-Techa.

Diurnal and seasonal variability of gasoline-related volatile organic compound emissions in Riverside, California.  

PubMed

On- and off-road mobile sources are the dominant contributors to urban anthropogenic volatile organic compound (AVOC) emissions. Analyses of gasoline samples from California for both summer and winter indicate significant differences in liquid fuel and vapor chemical composition due to intentional seasonal adjustments. Ambient concentrations of 55 VOCs were measured via in situ gas chromatography in the 2005 Study of Organic Aerosols at Riverside (SOAR) during both summer and fall. A chemical mass balance analysis was used to differentiate vapor pressure-driven VOC emissions from other motor vehicle-related emissions such as tailpipe exhaust. Overall, fuel vapor emissions accounted for 31 +/- 2% of gasoline-related VOC in Riverside; California's emission factor model similarly estimates 31% of gasoline-related VOC emissions are fuel vapor. The diurnal pattern of vapor pressure-driven VOC source contributions is relatively stable around 10 microg/m3, while whole gasoline (i.e., tailpipe) contributions peak at approximately 60 microg/m3 during the morning commute. There is no peak in whole gasoline source contributions during the afternoon, due to rapid dilution associated with high mixing heights and wind speeds in the Riverside area. The relationship between estimated gasoline-related VOC and observed carbon monoxide concentrations in this study is similar to California's 2005 emission inventory; we calculated a VOC to CO mass ratio of 0.086 +/- 0.006 (95% CI) compared to 0.097 in the emission inventory for all gasoline-related sources.

Monitoring and analysis of combined sewer overflows, Riverside and Evanston, Illinois, 1997-99  

USGS Publications Warehouse

The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, collected and analyzed flow data in combined sewer systems in Riverside and Evanston, northeastern Illinois, from March 1997 to December 1999. Continuous 2- and 5-minute stage and velocity data were collected during surcharged and nonsurcharged conditions at 12 locations. Mass balances were calculated to determine the volume of water flowing through the tide-gate openings to the Des Plaines River and the North Shore Channel and to determine the volume of water flowing past the sluice gate to the deep tunnel. The sewer systems consist of circular pipes ranging in diameter from 0.83 feet to 10.0 feet, elliptical siphon pipes, ledges, and tide and sluice gates. Pipes were constructed of either brick and mortar or concrete, and ranged from having smooth surfaces to rough, pitted and crumbling surfaces. One pipe was noticeably affected by water infiltration from saturated ground. During data analysis, many assumptions were necessary because of the complexity of the flow data and sewer-system configurations. These assumptions included estimating the volume of water entering an interceptor sewer at the ''Gage Street pipe'' at Riverside, the effect of infiltration on the ''brick pipe'' at Riverside, and the minimum velocity required for the meter to make an accurate velocity determination. Other factors affecting the analysis of flow data included possible non-instrumented sources of inflow, and backwater conditions in some pipes, which could have caused error in the data analysis. Variations of these assumptions potentially could cause appreciable changes to the final massbalance calculations. Mass-balance analysis at Riverside indicated a total inflow volume into chamber 3 of approximately 721,000 cubic feet (ft3) during April 22-26, 1999. Outflow volume to the Des Plaines River at Riverside through the tide gate was approximately 132,000 ft3; outflow volume to the deep tunnel through the sluice gate was approximately 267,000 ft3. The mass-balance analysis at Evanston indicated a total inflow volume into chamber 3 of approximately 5,970,000 ft3 during April 21-26, 1999. The outflow volume to the North Shore Channel through the tide gates at Evanston was approximately 2,920,000 ft3; outflow volume to the deep tunnel through the sluice gates was approximately 3,050,000 ft3.

The UC-LLNL Regional Climate System Model  

SciTech Connect

The UC-LLNL Regional Climate System Model has been under development since 1991. The unique system simulates climate from the global scale down to the watershed catchment scale, and consists of data pre- and post- processors, and four model components. The four model components are (1) a mesoscale atmospheric simulation model, (2) a soil-plant-snow model, (3) a watershed hydrology-riverflow model, and (4) a suite of crop response models. The first three model components have been coupled, and the system includes two-way feedbacks between the soil-plant-snow model and the mesoscale atmospheric simulation model. This three-component version of RCSM has been tested, validated, and successfully used for operational quantitative precipitation forecasts and seasonal water resource studies over the southwestern US. We are currently implementation and validating the fourth component, the Decision Support system for Agrotechnology Transfer (DSSAT). A description of the UC-LLNL RCSM and some recent results are presented.

Observations of Unresolved Photospheric Magnetic Fields in Solar Flares Using Fe uc(i) and Cr uc(i) Lines  

NASA Astrophysics Data System (ADS)

The structure of the photospheric magnetic field during solar flares is examined using echelle spectropolarimetric observations. The study is based on several Fe uc(i) and Cr uc(i) lines observed at locations corresponding to brightest H? emission during thermal phase of flares. The analysis is performed by comparing magnetic-field values deduced from lines with different magnetic sensitivities, as well as by examining the fine structure of I±V Stokes-profiles' splitting. It is shown that the field has at least two components, with stronger unresolved flux tubes embedded in weaker ambient field. Based on a two-component magnetic-field model, we compare observed and synthetic line profiles and show that the field strength in small-scale flux tubes is about 2 - 3 kG. Furthermore, we find that the small-scale flux tubes are associated with flare emission, which may have implications for flare phenomenology.

Determinants of scientific output: an in-depth view of the productivity of tropical botanist and conservationist, Luis Diego Gómez Pignataro.  

PubMed

Bibliometric studies have found that male researchers have their greatest productivity around the age of 40, that female researchers produce less than their male colleagues, that incentives for collaboration are slow to affect productivity and that, just like humans, research institutes become larger, less productive, more expensive to maintain and less able to raise money as they grow old. Almost invariably, these conclusions come from statistical studies of large numbers of European and American scientists, and there are practically no studies about tropical researchers. We present an in-depth analysis of the productivity of an internationally recognized tropical botanist and conservationist, Luis Diego Gómez Pignataro, based on the totality of his published work and on our own knowledge, as co-workers and friends, of the life frame in which that scientific output was produced. His life output departs from the expected pattern in that he had the highest productivity before reaching the expected peak productivity age, and that when he reached it his productivity fell and never recovered. Furthermore, marriage did not produce the expected fall in productivity. A close analysis of his life indicates that in the middle of his career he switched to intense teaching and conservation activities, and this better explains why his output of scientific research articles was low afterwards. This switch may occur in other tropical scientists. PMID:21246981

Hourly Speciated Organic Aerosol Composition in Riverside, CA during SOAR 2005  

NASA Astrophysics Data System (ADS)

Thermal Desorption Aerosol GC/MS-FID (TAG) is a new in-situ instrument to identify and quantify organic aerosol chemical composition with one hour time resolution. Atmospheric particles are collected by means of humidification and inertial impaction. The sample is then thermally desorbed onto a GC column, where it is separated into individual compounds which are identified and quantified using a quadrupole mass spectrometer (MS) and flame ionization detector (FID). With the exception of periodic manually applied calibration standards, TAG is fully automated, offering around the clock measurements to determine diurnal, weekly, and seasonal patterns in organic aerosol composition. The summer and fall of 2005 offered a unique opportunity for TAG to operate in parallel with a large suite of organic aerosol instrumentation, including several Aerodyne AMS instruments, three ATOFMS instruments, several high volume filter samplers, two EC/OC monitors, along with other aerosol and gas phase instrumentation as part of the Study of Organic Aerosol at Riverside (SOAR) campaign at the University of California, Riverside. We will present initial TAG particle source apportionment results, including separation of the influence from particle sources such as biomass combustion, vehicle emissions, pesticides, biogenic aerosol, and oxidation of biogenic and anthropogenic precursor gases leading to secondary organic aerosol (SOA) formation. We will also present ambient air observations of gas-particle partitioning as a function of molecular size and functional groups.

Heavy Metal Contaminated Soils in Riverside Park, Milwaukee, WI: Character, Bioavailability, and Distribution  

NASA Astrophysics Data System (ADS)

Prior to being breached in 1990, the North Avenue Dam on the Milwaukee River had created a 2.5-mile impoundment for over 150 years. Upstream urban runoff and industrial pollution resulted in the deposition of heavy metal rich sediments in the slow moving waters of the impoundment. After the dam removal, the river returned to a more natural flowpath and as the river narrowed, newly exposed riverbed was annexed as part of Riverside Park, enabling ecological recovery efforts on the river and riparian zones. However, these newly exposed soils are enriched with heavy metal contaminants, most notably, Pb, Zn, Cd, Cu, and Ni, concentrated by the impoundment. The current study has analyzed the location and concentrations of these trace metals, as well as their mobility and availability. This study is being conducted in conjunction with the Urban Ecology Center, a nonprofit environmental organization located in Riverside Park that is dedicated to serving the local community and urban youth while restoring and protecting the natural areas along the Milwaukee River. Analyses have included determination of general soil parameters such as particle size, organic content, and point of zero charge analyses. Beyond bulk chemical analysis, we have conducted selective sequential extractions to estimate the chemical speciation of these elements, which showed that approximately 30 percent of contaminants are highly available. Additionally, the soils have been analyzed with an Electron Microprobe to directly observe phase relationships of metals in the soils. Microprobe and other analyses have shown that heavy metals are associated with a variety of phases, including Mn and Fe oxy-hydroxides, and vary in concentration and phase relationships with depth and distance from the river. Finally, a field-portable x-ray fluorescence spectrometer (pXRF), coupled with GPS data, is being used to create a geochemical map of heavy metal distributions throughout the park.

Characterizing urbanization, and agricultural and conservation land-use change in Riverside County, California, USA.  

PubMed

Monitoring trends in urbanization and land use related to population growth and changing social and economic conditions is an important tool for developing in land use and habitat conservation policy. We analyzed urbanization and agricultural land-use change in Riverside County, California from 1984 to 2002, comparing maps every two years on the basis of aerial photographs. Matrix analysis combined with information theory was applied to study land type conversion. Results showed that the total area of "Urban and Built-Up Land" increased the most whereas total area of "Prime Farmland" decreased most. Land-use characterized as "Grazing Land,"Farmland of Local Importance," and "Farmland of Statewide Importance" also decreased. Mean patch size also decreased for "Grazing Land,"Water Area,"Other Land," and "Prime Farmland." The diversity of land types decreased dramatically after 1992. Urbanization patterns were different among three city groups (Riverside City, Coachella Valley, and Blythe), indicating the different times for "leapfrog" development in the three areas. Furthermore, the unpredictability and change in composition of land use increased after 1996 due to intensified urbanization. If the current driving forces continue, our model projects that in 2020 the area of "Urban and Built-Up Land" may increase between 25% and 39% in comparison with 2002. Percentages of most agricultural land types are projected to decrease, especially "Farmland of Local Importance,"Prime Farmland," and "Farmland of Statewide Importance." If the county's goal is to preserve agricultural lands and natural biodiversity, while maintaining sustainable development, current land-use policies and practices should be changed. This study demonstrates new useful methods for monitoring and detection of change of land-use processes. PMID:20586769

Linking academic and clinical missions: UC Davis' integrated AHC.  

PubMed

Academic health centers (AHCs) rely on cross-subsidization of education and research programs by the clinical enterprise, but this is becoming more challenging as clinical reimbursements decline. These new realities provide an important opportunity to reevaluate the relationships between medical schools and academic medical centers. The authors examine the benefits of their ongoing commitment to create a fully integrated AHC at the University of California (UC) Davis, discussing strategies that serve as catalysts for continued growth. They explore how investments of proceeds from the clinical enterprise directly enhance educational and research initiatives, which, in turn, increase the success of patient-care programs. This has created a cycle of excellence that leads to an enhanced reputation for the entire health system. One strategy involves using clinical margins to "prime the pump" in anticipation of major research initiatives, resulting in rapid increases in external research funding and academic recognition. In turn, this facilitates recruitment of high-quality faculty and staff, improving the ability to deliver expert clinical care. The overall enhanced institutional reputation positions both the clinical and academic programs for further success. The authors posit that such approaches require executive-level commitment to a single strategic vision, unified leadership, and collaborative financial and operational decision making. Adopting such changes is not without challenges, which are discussed, but the authors suggest that an integrated AHC fosters optimized operations, enhanced reputation, and stronger performance across all mission areas. They also provide examples of how the UC Davis Health System has thus attracted philanthropists and investments from the private sector. PMID:18728433

The 2005 Study of Organic Aerosols at Riverside (SOAR-1): instrumental intercomparisons and fine particle composition  

NASA Astrophysics Data System (ADS)

Multiple state-of-the-art instruments sampled ambient aerosol in Riverside, California during the 2005 Study of Organic Aerosols at Riverside (SOAR) to investigate sources and chemical composition of fine particles (PMf) in the inland region of Southern California. This paper briefly summarizes the spatial, meteorological and gas-phase conditions during SOAR-1 (15 July-15 August) and provides detailed intercomparisons of complementary measurements and average PMf composition during this period. Daily meteorology and gas-phase species concentrations were highly repetitive with meteorological and gas-phase species concentrations displaying clear diurnal cycles and weekday/weekend contrast, with organic aerosol (OA) being the single largest component contributing approximately one-third of PMf mass. In contrast with historical characterizations of OA in the region, several independent source apportionment efforts attributed the vast majority (~80%) of OA mass during SOAR-1 to secondary organic aerosol (SOA). Given the collocation of complementary aerosol measurements combined with a dominance of SOA during SOAR-1, this paper presents new results on intercomparisons among several complementary measurements and on PMf composition during this period. Total non-refractory submicron (NR-PM1) measurements from a high-resolution aerosol mass spectrometer (HR-AMS) are compared with measurements by tapered element oscillating microbalances (TEOM) including a filter dynamics measurement system (TEOMFDMS). NR-PM1 is highly correlated with PM2.5 TEOMFDMS measurements and accounts for the bulk of PM2.5 mass with the remainder contributed primarily by refractory material. In contrast, measurements from a heated TEOM show substantial losses of semi-volatile material, including ammonium nitrate and semi-volatile organic material. Speciated HR-AMS measurements are also consistent and highly correlated with several complementary measurements, including those of a collocated compact AMS (C-AMS). Finally, elemental analysis (EA) of HR-AMS OA spectra allows direct comparison of HR-AMS organic carbon (OC) with measurements from two collocated Sunset thermal-optical semi-continuous monitors, and investigation of the elemental composition of OA in Riverside. While HR-AMS and base OC measurements from both Sunset instruments are similar within the combined uncertainties, a correction intended to account for the loss of semivolatile OC from the Sunset yields OC measurements ~30% higher than either HR-AMS or base Sunset measurements. Oxygen is the main heteroatom of ambient OA during SOAR-1 with a minimum atomic O/C of 0.28 during the morning rush hour and maximum of 0.42 during the afternoon. H/C is broadly anti-correlated with O/C, while N/C and S/C (excluding organonitrate (ON) and organosulfate (OS) functionalities) are far lower than O/C at about 0.015 and ~0.001, respectively. O/C, N/C, and S/C increase by 21%, a factor of 2, and a factor of 30, respectively, while H/C changes little when ON and OS estimates are included. This implies that ON account for ~1/2 of the organic nitrogen while OS dominate organic sulfur at this location. Accounting for the estimated ON and OS also improves the agreement between anions and cations measured by HR-AMS by ~8%, while amines have a very small impact (1%) on this balance.

Hydrologic and Geologic Reconnaissance of Pinto Basin, Joshua Tree National Monument, Riverside County, California  

USGS Publications Warehouse

Pinto basin, in the north-central part of Riverside County, Calif., is a typical desert valley formed by downfaulting along several major fault zones. The valley is filled with alluvium, and ground water in the alluvium discharges as subsurface outflow through an alluvium-filled gap at the east end of the valley. Occasionally surface water from cloudburst floods also discharges in a wash through the gap at the east end of the valley. A northeastward extension of the major fault along the south side of the valley acts as a barrier to the discharge of ground water from the valley. The average ground-water gradient is less than 1 foot per mile across the main part of the valley above this barrier, but the water level drops abruptly across the fault. The ground-water storage capacity of the uppermost 100 feet of saturated alluvium beneath the central valley area is estimated to be about 230,000 acre-feet. All this water in storage occurs at depths greater than 95 feet below the land surface and cannot be reached by plants or animals. During 1959 virtually all the water pumped in the area was withdrawn from storage. However, the quantity of water pumped is small in relation to the total quantity in storage. Except for a small decline in head, no evidence indicates that the pumping will greatly impair the yield for many years or cause the water to deteriorate in quality.

Modeling analysis of the lymphocytopoiesis dynamics in chronically irradiated residents of Techa riverside villages.  

PubMed

A biologically motivated dynamical model of the lymphocytopoietic system in irradiated humans is applied here to analyze the data obtained under hematological examinations of residents of Techa riverside villages. Those people were exposed to chronic irradiation with varying dose rates, due to the radioactive contamination of the river basin by the Mayak Production Association. Modeling studies revealed the relationship between the dynamics of the lymphocytopoietic system in the examined individuals and the variation of dose rate over the considered period of time. It is found that the developed model is capable of reproducing the decreased level of blood lymphocyte concentration observed during the period of maximum radiation exposure, the recovery processes in the system observed during the period of decreasing dose rate, as well as the enhanced mitotic activity of bone marrow precursor cells in this hematopoietic lineage observed during the entire period under consideration. Mechanisms of these effects of chronic irradiation on the human lymphocytopoietic system are elucidated based on the applied model. The results obtained demonstrate the efficiency of the developed model in the analysis, investigation, and prediction of effects of chronic irradiation with varying dose rate on the human lymphocytopoietic system. In particular, the developed model can be used for predicting any radiation injury of this vital system in people exposed to chronic irradiation due to environmental radiological events, such as anthropogenic radiation accidents or radiological terroristic attacks.

The 2005 Study of Organic Aerosols at Riverside (SOAR-1): instrumental intercomparisons and fine particle composition  

NASA Astrophysics Data System (ADS)

Multiple state-of-the-art instruments sampled ambient aerosol in Riverside, California during the 2005 Study of Organic Aerosols at Riverside (SOAR) to investigate the chemical composition and potential sources of fine particles (PMf) in the inland region of Southern California. In this paper, we briefly summarize the spatial, meteorological and gas-phase conditions during SOAR-1 (15 July-15 August), provide detailed intercomparisons of high-resolution aerosol mass spectrometer (HR-AMS) measurements against complementary measurements, and report the average composition of PMf including the composition of the organic fraction measured by the HR-AMS. Daily meteorology and gas-phase species concentrations were highly consistent, displaying clear diurnal cycles and weekday/weekend contrast. HR-AMS measurements of non-refractory submicron (NR-PM1) mass are consistent and highly correlated with those from a filter dynamics measurement system tapered-element oscillating microbalance (TEOM), while the correlation between HR-AMS and heated TEOM measurements is lower due to loss of high volatility species including ammonium nitrate from the heated TEOM. Speciated HR-AMS measurements are also consistent with complementary measurements as well as with measurements from a collocated compact AMS while HR-AMS OC is similar to standard semi-continuous Sunset measurements within the combined uncertainties of both instruments. A correction intended to account for the loss of semi-volatile OC from the Sunset, however, yields measurements ~30% higher than either HR-AMS or standard Sunset measurements. On average, organic aerosol (OA) was the single largest component of PMf. OA composition was investigated using both elemental analysis and positive matrix factorization (PMF) of HR-AMS OA spectra. Oxygen is the main heteroatom during SOAR-1, with O/C exhibiting a diurnal minimum of 0.28 during the morning rush hour and maximum of 0.42 during the afternoon. O/C is broadly anti-correlated with H/C, while N/C and S/C (excluding organonitrate (ON) and organosulfate (OS) functionalities) are far lower than O/C at about 0.015 and ~0.001, respectively. When ON and OS estimates are included O/C, N/C, and S/C increase by factors of 1.21, 2, and 30, respectively, while H/C changes are insignificant. The increase in these ratios implies that ON accounts for ~1/2 of the organic nitrogen while OS dominate organic sulfur at this location. Accounting for the estimated ON and OS also improves the agreement between anions and cations measured by HR-AMS by ~8%, while amines have only a very small impact (1%) on this balance. Finally, a number of primary and secondary OA components were resolved by PMF. Among these a hydrocarbon-like OA and two minor, local OA components, one of which was associated with amines, were attributed to primary emissions and contributed a minor fraction (~20%) of OA mass. The remaining OA mass was attributed to a number of secondary oxidized OA (OOA) components including the previously-identified low-volatility and semi-volatile OOA components. In addition, we also report for the first time the presence of two additional OOA components.

When water quantity regulation is not water quantity regulation. Riverside v. Andrews, 568 F. Supp. 583 (D. Colo. 1983)  

SciTech Connect

A review of the Riverside v. Andrews case concludes that basing a nationwide permit on a narrow reading of the Corps of Engineers' responsibilities and a narrow interpretation of its authority would be contrary to the Corps' evolution during the past 20 years, contrary to the intent of Congress, and irreconcilable with the stated purpose of environmental enhancement under the Clean Water Act. The environmental goals of the Act depend upon authorized agencies considering all the foreseeable adverse environmental effects of activities before granting permits. Claims of states' rights to regulate water quantity cannot override the federal environmental mandate.

Elevated blood lead levels in a riverside population in the Brazilian Amazon.  

PubMed

Lead (Pb) is recognized as one of the most toxic metals. Sources of Pb exposure have been widely documented in North America, and the removal of Pb additives from gasoline was reflected in a dramatic lowering of blood Pb concentration. In Latin America, the removal of Pb from gasoline resulted in decreased exposure, but Pb levels in many areas remain high due to occupational and environmental sources of exposure. While many of the Pb sources have been identified (mining, industries, battery recycling, lead-based paint, ceramics), new ones occasionally crop up. Here we report on blood Pb (B-Pb) levels in remote riverside communities of the Brazilian Amazon. Blood Pb (B-Pb) levels were determined in 448 persons from 12 villages of the Lower Tapajós River Basin, Pará, Brazil. Socio-demographic and dietary information, as well as occupational, residential and medical history was collected using an interview-administered questionnaire. B-Pb, measured by ICP-MS, showed elevated concentrations. Mean B-Pb was 13.1 microg/dL +/- 8.5, median B-Pb was 11.2 microg/dL and ranged from 0.59 to 48.3 microg/dL. Men had higher B-Pb compared to women (median: 15.3 microg/dL vs 7.9 microg/dL respectively). B-Pb increased with age for women, while it decreased for men. For both genders, B-Pb decreased with education. There were significant differences between villages. Exploratory analyses, using linear partition models, showed that for men B-Pb was lower among those who were involved in cattle-raising, and higher among those who hunted, farmed and fished. The distribution profile of B-Pb directed us towards artisanal transformation of manioc to flour (farinha), which requires heating in a large metal pan, with stirring primarily done by young men. In the village with the highest B-Pb, analysis of Pb concentrations (dry weight) of manioc (prior to transformation) and farinha (following transformation) from 6 houses showed a tenfold increase in Pb concentration (mean: 0.017 +/- 0.016 to 0.19 +/- 0.10 microg/g). This was confirmed in one of these villages where we sampled manioc paste (just before roasting) and the roasted farinha (0.05 microg/g vs 0.20 microg/g). While there may be other sources (ammunition, sinkers for fishing nets), the high concentrations in farinha, a dietary staple, assuredly makes an important contribution. Further action needs to reduce Pb sources in this region. PMID:19389665

Yeast UCS proteins promote actomyosin interactions and limit myosin turnover in cells.  

PubMed

Two functions are proposed for the conserved family of UCS proteins: helping to fold myosin motor proteins and stimulating the motor function of folded myosins. We examined both functions in yeast. The fission yeast UCS protein (Rng3p) concentrates in nodes containing myosin-II (Myo2) and other proteins that condense into the cytokinetic contractile ring. Both the N-terminal (central) and C-terminal (UCS) domains of Rng3p can concentrate independently in contractile rings, but only full-length Rng3p supports contractile ring function in vivo. The presence of Rng3p in ATPase assays doubles the apparent affinity (K(ATPase)) of both native Myo2 and recombinant heads of Myo2 for actin filaments. Rng3p promotes gliding of actin filaments by full-length Myo2 molecules, but not Myo2 heads alone. Myo2 isolated from mutant strains defective for Rng3p function is soluble and supports actin filament gliding. In budding yeast the single UCS protein (She4p) acts on both myosin-I isoforms (Myo3p and Myo5p) and one of two myosin-V isoforms (Myo4p). Myo5p turns over approximately 10 times faster in she4Delta cells than wild-type cells, reducing the level of Myo5p in cells 10-fold and in cortical actin patches approximately 4-fold. Nevertheless, Myo5p isolated from she4Delta cells has wild-type ATPase and motility activities. Thus, a fraction of this yeast myosin can fold de novo in the absence of UCS proteins, but UCS proteins promote myosin stability and interactions with actin. PMID:18523008

Risk assessment of mercury exposure through fish consumption by the riverside people in the Madeira Basin, Amazon, 1991.  

PubMed

Aquatic food chain mercury pollution is one of the consequences of the gold rush in the Amazon, which started in the late 1970s. This paper addresses the risks of methylmercury (MeHg) toxicity by a riverside population of heavy fish eaters along the Madeira river, in the Amazon, based on their hair mercury (Hg) concentration. Given the vulnerability of the developing nervous system, NOEL/LOEL values were used based on prenatal (LOELp = 0.7 microgram/ kg bw), and adult and childhood (LOELa = 3 micrograms/kg bw) Hg exposures. Based on hair Hg concentrations, we observed that approximately 95% of infants were at risk of absorbing Hg through the previous placental exposure, and/or by ingesting Hg from mother's milk, and/or fish consumption, at a level as great as the LOELp. The hazard quotient derived from the LOELp for neurobehavioral effects was 64 based on an estimated mean Hg daily intake of 4.5 micrograms/kg bw. Approximately 45% of the mothers of the infants and other women of child bearing age were at risk of ingesting Hg at a level equivalent to the LOELp. This also translates into a derived hazard quotient for neurobehavioral effects of 17 for all potential mothers in the population. The non-infant population at the highest risk was fish-eating children under 5 years old. This sub-population had a mean estimated Hg daily intake of 6.4 micrograms/kg bw. This resulted in a probability that almost 60% of this sub-population ingested Hg at a level equivalent to the LOELa or higher. For this sub-population, there was a hazard quotient of 21. These data strongly indicate that the young children of this riverside fish-eating population may be ingesting Hg doses that have been correlated with neurological damage from Hg poisoning.

UC781 microbicide gel retains anti-HIV activity in cervicovaginal lavage fluids collected following twice-daily vaginal application.  

PubMed

The potent nonnucleoside reverse transcriptase inhibitor UC781 has been safety tested as a vaginal microbicide gel formulation for prevention of HIV-1 sexual transmission. To investigate whether UC781 retained anti-infective activity following exposure to the female genital tract, we conducted an ex vivo analysis of the UC781 levels and antiviral activity in cervicovaginal lavage (CVL) fluids from 25 Thai women enrolled in a 14-day safety trial of twice-daily vaginal application of two concentrations of the UC781 microbicide gel. CVL samples were collected from women in the 0.1% (n = 5), 0.25% (n = 15), and placebo (n = 5) gel arms following the first application of gel (T(15 min)) and 8 to 24 h after the final application (T(8-24 h)) and separated into cell-free (CVL-s) and pelletable (CVL-p) fractions. As UC781 is highly hydrophobic, there were significantly higher levels of UC781 in the CVL-p samples than in the CVL-s samples for the UC781 gel arms. In T(8-24 h) CVL-p samples, 2/5 and 13/15 samples collected from the 0.1% and 0.25% UC781 gel arms, respectively, efficiently blocked infection with ? 4 log(10) 50% tissue culture infective dose (TCID(50)) of a CCR5-tropic CRF01_AE HIV-1 virus stock. Independent of the arm, the 11 CVL-p samples with UC781 levels of ? 5 ?g/CVL sample reduced infectious HIV by ? 4 log(10) TCID(50). Our results suggest that the levels and anti-infective activities of UC781 gel formulations are likely to be associated with a cellular or pelletable component in CVL samples. Therefore, cellular and pelletable fractions should be assayed for drug levels and anti-infective activity in preclinical studies of candidate microbicides. PMID:22508307

Investigation of the diffusion of atomic fission products in UC by density functional calculations  

NASA Astrophysics Data System (ADS)

Activation energies of U and C atoms self-diffusion in UC, as well as activation energies of hetero-diffusion of fission products (FPs) are investigated by first-principles calculations. According to a previous study which showed a likely U site occupation was favoured for all the FPs, their diffusion is restricted to the uranium sublattice of UC in the present study. In this framework, long-range displacements are only possible through a concerted mechanism with a surrounding uranium vacancy. Using the apparent formation energies of the uranium vacancy defect calculated in our previous study and the classical approach used in UO2 by Andersson et al., the activation energies of the main fission products in the various stoichiometric domains have been calculated. The results are compared to those obtained with the five frequency model applied to two representative fission products, Xe and Zr. Interestingly, despite strong differences of formalism, both models provided similar activation energies.

Space Station UCS antenna pattern computation and measurement. [UHF Communication Subsystem  

NASA Technical Reports Server (NTRS)

The purpose of this paper is to analyze the interference to the Space Station Ultrahigh Frequency (UHF) Communication Subsystem (UCS) antenna radiation pattern due to its environment - Space Station. A hybrid Computational Electromagnetics (CEM) technique was applied in this study. The antenna was modeled using the Method of Moments (MOM) and the radiation patterns were computed using the Uniform Geometrical Theory of Diffraction (GTD) in which the effects of the reflected and diffracted fields from surfaces, edges, and vertices of the Space Station structures were included. In order to validate the CEM techniques, and to provide confidence in the computer-generated results, a comparison with experimental measurements was made for a 1/15 scale Space Station mockup. Based on the results accomplished, good agreement on experimental and computed results was obtained. The computed results using the CEM techniques for the Space Station UCS antenna pattern predictions have been validated.

Over-estimation of glucose-6-phosphatase activity in brain in vivo. Apparent difference in rates of (2-TH)glucose and (U- UC)glucose utilization is due to contamination of precursor pool with UC-labeled products and incomplete recovery of UC-labeled metabolites  

SciTech Connect

Significant dephosphorylation of glucose 6-phosphate due to glucose-6-phosphatase activity in rat brain in vivo was recently reported. The evidence was an apparent more rapid TH than UC loss from the glucose pool and faster (2-TH)glucose than (U- UC)glucose utilization following pulse labeling of the brain with (2-TH,U- UC)glucose. Radiochemical purity of the glucose and quantitative recovery of the labeled products of glucose metabolism isolated from the brain were obviously essential requirements of their study, but no evidence for purity and recovery was provided. When we repeated these experiments with the described isolation procedures, we replicated the results, but found that: 1) the precursor glucose pool contained detritiated, UC-labeled contaminants arising from glucose metabolism, particularly 2-pyrrolidone-5-carboxylic acid derived from ( UC)glutamine; 2) ( UC)glucose metabolite were not quantitatively recovered; 3) the procedure used to isolate the glucose itself produced detritiated, UC-labeled derivatives of (2-TH,U-14C)glucose. These deficiencies in the isolation procedures could fully account for the observations that were interpreted as evidence of significant glucose 6-phosphate dephosphorylation by glucose-6-phosphatase activity. When glucose was isolated by more rigorous procedures and its purity verified in the present studies, no evidence for such activity in rat brain was found.

UC San Diego study identifies two cancer drugs that may target a form of glioblastoma:  

Cancer.gov

Scientists at the University of California, San Diego School of Medicine and UC San Diego Moores Cancer Center, in collaboration with colleagues in Boston and South Korea, say they have identified a novel gene mutation that causes at least one form of glioblastoma (GBM), the most common type of malignant brain tumor... Perhaps more importantly, the researchers found that two drugs already being used to treat other forms of cancer effectively prolonged the survival of mice modeling this particular form of GBM.

Sequence specificity of DNA-psoralen photoproduct formation in supercoiled plasmid DNA (pUC19)  

Microsoft Academic Search

Supercoiled pUC19 DNA, photoreacted with psoralen derivatives (xanthotoxin (8-methoxypsoralen, 8-MOP), 4,5?,8-trimethylpsoralen (TMP) and angelicin), influences the enzymatic activity of restriction enzymes in a different manner, although all the enzymes employed contain, within their recognition sites, suitable nucleic acid bases for photoproduct formation. The activity of the enzymes is strongly influenced by the photomodification of thymine residues within their recognition sites.

In vitro batch cultures of gut microbiota from healthy and ulcerative colitis (UC) subjects suggest that sulphate-reducing bacteria levels are raised in UC and by a protein-rich diet.  

PubMed

Imbalances in gut microbiota composition during ulcerative colitis (UC) indicate a role for the microbiota in propagating the disorder. Such effects were investigated using in vitro batch cultures (with/without mucin, peptone or starch) inoculated with faecal slurries from healthy or UC patients; the growth of five bacterial groups was monitored along with short-chain fatty acid (SCFA) production. Healthy cultures gave two-fold higher growth and SCFA levels with up to ten-fold higher butyrate production. Starch gave the highest growth and SCFA production (particularly butyrate), indicating starch-enhanced saccharolytic activity. Sulphate-reducing bacteria (SRB) were the predominant bacterial group (of five examined) for UC inocula whereas they were the minority group for the healthy inocula. Furthermore, SRB growth was stimulated by peptone presumably due to the presence of sulphur-rich amino acids. The results suggest raised SRB levels in UC, which could contribute to the condition through release of toxic sulphide. PMID:23941288

An Integrated Study of Geoelectric Vertical Sounding and Hydrogeochemistry in the Riverside Alluvium around Buyeo Area, Korea  

NASA Astrophysics Data System (ADS)

The water quality of alluvial aquifers in agricultural areas is sensitive to the behaviour of agricultural chemicals (e.g., fertilizers, pesticides, and lime) and, also, to the geologic conditions. It is important to know the characteristics of the aquifers (e.g., depth, spatial distribution, and soil types) and the relationship between subsurface geology and the groundwater contamination for its effective use and management in the future. In order to provide the subsurface information of the lithology and the groundwater zone for hydrogeologic interpretations, an integrated study using twenty vertical electric soundings (VES), direct observation of lithology from two boreholes and hydrochemical data from irrigation well has been conducted in the riverside alluvium near Buyeo area, Korea. Main results of this study are as follows. The depth of main groundwater table is getting slightly deeper toward the river. The boundary between surface sandy and silty soils extends to the subsurface at depth of groundwater table. The vestige of an ancient river channel, such as an oxbow lake, can be identified by a lateral continuation of perched aquifer parallel to the river on the resistivity profiles. This perched aquifer materials are composed of clay-rich silt soils, which prohibit the infiltration of oxygen and nitrate from the land surface. Therefore, the groundwater of the main aquifer below the oxbow lake shows the very low NO3 level and Eh values under the strong anoxic condition. Surface resistivity contour map indicates that the resistivity varies with a NW-SE trending zonal distribution and increases toward the river. This result shows an agreement with the spatial distribution of surface soils, implying that the variation of surface resistivity is mainly controlled by surface lithology or soil type. On the other hand, the distribution of water resistivities is correlated with that of total dissolved solids (TDS) concentration, while the earth resistivity of aquifer shows a different spatial distribution from those of water resistivity and TDS. It is interpreted that the earth resistivity of aquifer might represent the variations of soil type rather than water chemistry in the study area. The present study shows that the geoelectric sounding survey with the complement of borehole lithology and hydrochemical data can provide an inexpensive and useful method for delineating the subsurface hydrogeology in the riverside alluvial aquifer.

A process was developed for the production of high-density UO/sub 2/-UC/sub 2/ microspheres for use as fuel in HTGRs. This process applied thermochemical principles so that reaction and sintering could occur at the unusually low temperature of 1550/sup 0/C and neartheoretical densities could still be obtained. Temperatures previously used for carbothermic conversion are several hundred degrees higher./sup 12/ Reaction and sintering took place in two steps. The first was sintering in Ar-1% CO at 1550/sup 0/C for 4 h. which produced highly dense microspheres containing UO/sub 2/ and UC /SUB x/ O /SUB y/. The second required sintering in Ar-3% CO at 1550/sup 0/C for an additional 4 h to shift the thermodynamic equilibrium from UO/sub 2/ and UC /SUB x/ O /SUB y/ to UO/sub 2/ and UC/sub 2/. The highly dense structure was retained, while carbon from the carbon monoxide atmosphere reacted with UC /SUB x/ O /SUB y/ to form UO/sub 2/ and UC/sub 2/.

Use of airborne remote sensing to detect riverside Brassica rapa to aid in risk assessment of transgenic crops  

NASA Astrophysics Data System (ADS)

High resolution descriptions of plant distribution have utility for many ecological applications but are especially useful for predictive modeling of gene flow from transgenic crops. Difficulty lies in the extrapolation errors that occur when limited ground survey data are scaled up to the landscape or national level. This problem is epitomized by the wide confidence limits generated in a previous attempt to describe the national abundance of riverside Brassica rapa (a wild relative of cultivated rapeseed) across the United Kingdom. Here, we assess the value of airborne remote sensing to locate B. rapa over large areas and so reduce the need for extrapolation. We describe results from flights over the river Nene in England acquired using Airborne Thematic Mapper (ATM) and Compact Airborne Spectrographic Imager (CASI) imagery, together with ground truth data. It proved possible to detect 97% of flowering B. rapa on the basis of spectral profiles. This included all stands of plants that occupied >2m square (>5 plants), which were detected using single-pixel classification. It also included very small populations (<5 flowering plants, 1-2m square) that generated mixed pixels, which were detected using spectral unmixing. The high detection accuracy for flowering B. rapa was coupled with a rather large false positive rate (43%). The latter could be reduced by using the image detections to target fieldwork to confirm species identity, or by acquiring additional remote sensing data such as laser altimetry or multitemporal imagery.

Onchocerciasis transmission levels and Simulium damnosum complex biting activity at riverside and rice field sites in Sierra Leone.  

PubMed

Biting densities of the Simulium damnosum Theobald complex of blackflies and their levels of parasitism by Onchocerca volvulus (Leuckart) were compared at two ecologically contrasted sites in the Southern Province of Sierre Leone, West Africa: by the Tabe riverside close to Gbaiima village where onchocerciasis is hyperendemic (63.1% positive skin-snips) and in open rice fields 2 km from the mesoendemic (54.9%) village of Senehun. Using a combination of morphometric and enzyme electrophoresis techniques, the primary vector was found to belong to the S.sanctipauli subcomplex and was most probably S.soubrense 'B' (sensu Post, 1986). In the wet season biting activity took place throughout the day at the village, but had morning and evening peaks in the rice fields. Transmission of O.volvulus was detected at the village in all months except February-April, while in the rice fields it was detected only during September-November and May at one tenth the level of the village. There was a significant difference between the two sites in the proportion of parous flies carrying third stage larvae in the head, but not of other larval stages. PMID:2980195

[Immunomodulatory effect of UC-MSC on function of immunocytes of rats with collagen type II induced arthritis].  

PubMed

This study was purposed to observe the influence of umbilical cord mesenchymal stem cells (UC-MSC) on the peripheral blood CD4(+)CD25(+)regulatory T cells (Treg), Th17 cells and neutrophils in rats with collagen type II-induced arthritis(CIA), and to explore the regulating effect of UC-MSC transplantation on immunocyte subgroup. The rats wee divided into 3 groups: CIA group (model group), UC-MSC treated group and blank control group. The CIA rats were injected with UC-MSC via tail vein. The percentage of CD4(+)CD25(+) cells in peripheral blood and the expression of NCD11b on neutrophil surface in CIA rates was detected by flow cytometry (FCM), and the serum interleukin-17 (IL-17) was observed by enzyme-linked immunosorbent assay (ELISA). The results showed that the mean fluorescence intensity(MFI) of NCD11b and the level of IL-17 in the model group were significantly higher than those in the blank control group, and the ratio of CD4(+)CD25(+) cells were significantly lower (P < 0.05). The MIF of NCD11b and the level of IL-17 in the UC-MSC treated group were significantly lower than that in the model group (P < 0.05), while the proportion of CD4(+)CD25(+) Treg increased (P < 0.05). Since the fifth week, the above indicators in the UC-MSC group have almostly approached the control group. It is concluded that the UC-MSC can increase peripheral blood Treg proportion in CIA rat, inhibit the secretion of Th17 and the activity of neutrophils, reduce the immune inflammation reaction, decrease the release of proinflammatory factor, and induce immune reconstruction.

Theoretical study of the structure and bonding in ThC2 and UC2.  

PubMed

The electronic structure and various molecular properties of the actinide (An) dicarbides ThC(2) and UC(2) were investigated by relativistic quantum chemical calculations. We probe five possible geometrical arrangements: two triangular structures including an acetylide (C(2)) moiety, as well as the linear AnCC, CAnC, and bent CAnC geometries. Our calculations at various levels of theory indicate that the triangular species are energetically more favorable, while the latter three arrangements proved to be higher-energy structures. Our SO-CASPT2 calculations give the ground-state molecular geometry for both ThC(2) and UC(2) as the symmetric (C(2v)) triangular structure. The similar and, also very close in energy, asymmetric (C(s)) triangular geometry belongs to a different electronic state. DFT and single-determinant ab initio methods failed to distinguish between these two similar electronic states demonstrating the power of multiconfiguration ab initio methods to deal with such subtle and delicate problems. We report detailed data on the electronic structure and bonding properties of the most relevant structures. PMID:22191481

The Plasmid Complement of Lactococcus lactis UC509.9 Encodes Multiple Bacteriophage Resistance Systems.  

PubMed

Lactococcus lactis subsp. cremoris strains are used globally for the production of fermented dairy products, particularly hard cheeses. Believed to be of plant origin, L. lactis strains that are used as starter cultures have undergone extensive adaptation to the dairy environment, partially through the acquisition of extrachromosomal DNA in the form of plasmids that specify technologically important phenotypic traits. Here, we present a detailed analysis of the eight plasmids of L. lactis UC509.9, an Irish dairy starter strain. Key industrial phenotypes were mapped, and genes that are typically associated with lactococcal plasmids were identified. Four distinct, plasmid-borne bacteriophage resistance systems were identified, including two abortive infection systems, AbiB and AbiD1, thereby supporting the observed phage resistance of L. lactis UC509.9. AbiB escape mutants were generated for phage sk1, which were found to carry mutations in orf6, which encodes the major capsid protein of this phage. PMID:24814781

Insertion sequence ISPst4 activates pUC plasmid replication in Pseudomonas stutzeri.  

PubMed

Insertion sequences (IS) are important drivers of bacterial evolution. Here, we report a previously undescribed IS element (ISPst4) in Pseudomonas stutzeri, and its unusual interaction with plasmids introduced into this species. Transformation of the pUC19 derivative plasmid pUS23 into P. stutzeri yielded ampicillin-resistant transformants in P. stutzeri, but these grew very poorly. Plasmids recovered from the transformants frequently contained insertions of the IS elements ISPst4 and ISPst5. Hybridisation analysis showed that these two IS elements were common in P. stutzeri strains, but were not found in other pseudomonads. Insertions of ISPst4 in pUS23 were found predominantly between bla and oriV, and plasmids with this type of insertion were capable of robust replication in P. stutzeri, unlike pUS23. A promoter-containing region was localised to a 74 bp NcoI-SacI fragment within ISPst4, and we postulate that this promoter drives expression of the pUC oriV in P. stutzeri. This is the first report of IS transposition directly leading to an expansion of the effective host range of a plasmid, adding a new dimension to our understanding of the relationship between plasmids and IS elements.

Discovery Learning in Astronomy Laboratories at UC Berkeley: A Report from the Field  

NASA Astrophysics Data System (ADS)

We describe new developments in laboratory courses for Astrophysics majors in the Astronomy Department at the University of California at Berkeley, both from the "bottoms up" view of the courses' conception, design and practical teaching experience, and from the "top down" view of their financing and management, including some aspects of pure luck that allowed them to be constructed at less cost than one might have normally expected. We put particular emphasis on the courses' use of discovery learning techniques, pursued by students working in teams. The relation between these laboratory efforts in optical, radio and infrared astronomy and other changes in the major, which have led to an approximate doubling of the number of students majoring in Astrophysics at UC Berkeley, will also be outlined.

Fractionation of radioactivity in the milk of goats administered UC-aflatoxin B1  

SciTech Connect

A detailed fractionation of radioactivity in the milk of goats administered UC-aflatoxin B1 at low doses was performed. The milk collected in the first 24 h following dosing contained radioactivity equivalent to 0.45-1.1% of the dose given. The radioactivity in each sample was partitioned into 4 fractions: ether, protein, dichloromethane, and water-alcohol. Over 80% of the radioactivity was detected in the dichloromethane fraction, of which over 95% was attributable to aflatoxin M1. No aflatoxin B1 or other known aflatoxin metabolites were detected in any fraction. The results indicate that the major metabolite of aflatoxin B1 in goat milk is aflatoxin M1 and that other metabolites, including conjugates, are of minor significance.

The Chicago Public Schools (CPS)/University of Chicago (UC) Internet Project (CUIP) is a collaborative pilot project among the UC, CPS Central Administration, and 24 public schools in the Woodlawn, Hyde Park/ South Kenwood, and North Kenwood/Oakland neighborhoods. Our primary goal is connecting these schools to the Internet, emphasizing the continued support of the schools and their teachers after the computers and connections are in place. We work with principals, department heads, and individual teachers to create and nurture a self-sustaining computer culture that will both maintain the network systems and incorporate the technology into the curriculum. We also encourage the schools to take advantage of ther new connectivity by collaborating and sharing resources among themselves. Formal interactions are fostered with museums and research centers, locally and nationally. CUIP is committed to supporting these schools as they use the Internet to enhance student learning. CUIP's goals include: providing T-1 internet connectivity to 24 local schools, supporting the technology coordinator in each school in order to ensure continuous Internet connectivity, and developing effective technology plans, including technology upgrades; nurturing and supporting teachers interested in incorporating technology in their classroom; fostering an environment in which the students can acquire a wide range of comptuer skills appropriate to the current job market; and fostering similar community-based efforts, around Chicago and the nation. CUIP's milestones include: internet service connected to 12 schools; technology interns placed in some CUIP schools in collaboration with Governors State University; email provided to more than half of the 660 teachers in connected schools; and World Wide Web for Teachers, a summer class on curriculum uses of the Web, taught by CUIP staff to 23 of over 100 public school teacher applicants.

Results of a shallow seismic-refraction survey in the Little Valley area near Hemet, Riverside County, California  

USGS Publications Warehouse

Little Valley, a small locally named valley southeast of the city of Hemet in Riverside County, California, is being evaluated for development of a constructed wetland and infiltration area as part of a water-resources management program in the area. The valley is a granitic basin filled with unconsolidated material. In August 1993 and June and July 1994, the U.S. Geological Survey conducted a seismic-refraction survey consisting of four lines northwest of the valley, eight lines in the valley, and six lines northeast of the valley. Two interpretations were made for the lines: a two-layer model yielded an estimate of the minimum depths to bedrock and a three-layer model yielded the most likely depths to bedrock. Results of the interpretation of the three-layer model indicate that the unsaturated unconsolidated surface layer ranges in thickness from 12 to 83 feet in the valley and 24 to 131 feet northeast of the valley. The mean compressional velocity for this layer was about 1,660 feet per second. A saturated middle layer was detected in some parts of the study area, but not in others--probably because of insufficient thickness in some places; however, in order to determine the "most likely" depths to bedrock, it was assumed that the layer was present throughout the valley. Depths to this layer were verified on three seismic lines using the water level from the only well in the valley. Data for additional verification were not available for wells near Little Valley. The bedrock slope from most of Little Valley is down toward the northeast. Bedrock profiles show that the bedrock surface is very uneven in the study area. The interpreted most likely depth to bedrock in the valley ranged from land surface (exposed) to a depth of 176 feet below land surface, and northeast of the valley it ranged from 118 to 331 feet below land surface. Bedrock depths were verified using lithologic logs from test holes drilled previously in the area. On the basis of a measured mean compressional velocity of about 12,000 feet per second, the bedrock was interpreted to be weathered granite.

UC Davis researchers find oropharyngeal cancer patients with HPV have a more robust response to radiation therapy  

Cancer.gov

UC Davis cancer researchers have discovered significant differences in radiation-therapy response among patients with oropharyngeal cancer depending on whether they carry the human papillomavirus (HPV), a common sexually transmitted virus. The findings, published online today in The Laryngoscope Journal, could lead to more individualized radiation treatment regimens, which for many patients with HPV could be shorter and potentially less toxic.

Development and characterisation of a self-microemulsifying drug delivery systems (SMEDDSs) for the vaginal administration of the antiretroviral UC-781.  

PubMed

UC-781 is highly selective and potent against HIV-1. However, its hydrophobic nature (logP 5.1) and lack of aqueous solubility have limited its development as a HIV microbicide. Self-microemulsifying drug delivery systems (SMEDDSs) have been developed to enhance the water solubility and bioavailability of hydrophobic drugs, such as UC781. In this study, we show the development of UC781-loaded SMEDDS and their enhanced release of UC781 from hard gelatine capsules, when compared to UC781 powder only. The majority of antiretrovirals being evaluated as potential HIV microbicides are hydrophobic. Therefore, a SMEDDS formulation offers an alternative approach to enhancing the vaginal absorption of these microbicidal candidates. PMID:23159711

Source apportionment of 1 h semi-continuous data during the 2005 Study of Organic Aerosols in Riverside (SOAR) using positive matrix factorization  

NASA Astrophysics Data System (ADS)

Positive matrix factorization (PMF2) was used to elucidate sources of fine particulate material (PM 2.5) for a study conducted during July and August 2005, in Riverside, CA. One-hour averaged semi-continuous measurements were made with a suite of instruments to provide PM 2.5 mass and chemical composition data. Total PM 2.5 mass concentrations (non-volatile plus semi-volatile) were measured with an R&P filter dynamic measurement system (FDMS TEOM) and a conventional TEOM monitor was used to measure non-volatile mass concentrations. PM 2.5 chemical species monitors included a dual-oven Sunset monitor to measure both non-volatile and semi-volatile carbonaceous material, an ion chromatographic-based monitor to measure sulfate and nitrate and an Anderson Aethalometer to measure black carbon (BC). Gas phase data including CO, NO 2, NO x and O 3 were also collected during the sampling period. In addition, single-particle measurements were made using aerosol time-of-flight mass spectrometry (ATOFMS). Twenty different single-particle types consistent with those observed in previous ATOFMS studies in Riverside were identified for the PMF2 analysis. Finally, time-of-flight aerosol mass spectrometry (ToF-AMS) provided data on markers of primary and secondary organic aerosol. Two distinct PMF2 analyses were performed. In analysis 1, all the data except for the ATOFMS and ToF-AMS data were used in an initial evaluation of sources at Riverside during the study. PMF2 was able to identify six factors from the data set corresponding to both primary and secondary sources, primarily from automobile emissions, diesel emissions, secondary nitrate formation, a secondary photochemical associated source, organic emissions and Basin transported pollutants. In analysis 2, the ATOFMS and ToF-AMS data were included in the analysis. In the second analysis, PMF2 was able to identify 16 factors with a variety of both primary and secondary factors being identified, corresponding to both primary and secondary material from both anthropogenic and natural sources. Based on relationships with Basin meteorology, the PMF identified source profiles and diurnal patterns in the source concentrations, sources were identified as being of local origin or resulting from transport of pollutants across the Basin due to onshore flow. Good agreement was observed between the PMF2 predicted mass and the FDMS measured mass for both analyses.

Geologic map and digital database of the Porcupine Wash 7.5 minute Quadrangle, Riverside County, southern California  

USGS Publications Warehouse

This data set maps and describes the geology of the Porcupine Wash 7.5 minute quadrangle, Riverside County, southern California. The quadrangle, situated in Joshua Tree National Park in the eastern Transverse Ranges physiographic and structural province, encompasses parts of the Hexie Mountains, Cottonwood Mountains, northern Eagle Mountains, and south flank of Pinto Basin. It is underlain by a basement terrane comprising Proterozoic metamorphic rocks, Mesozoic plutonic rocks, and Mesozoic and Mesozoic or Cenozoic hypabyssal dikes. The basement terrane is capped by a widespread Tertiary erosion surface preserved in remnants in the Eagle and Cottonwood Mountains and buried beneath Cenozoic deposits in Pinto Basin. Locally, Miocene basalt overlies the erosion surface. A sequence of at least three Quaternary pediments is planed into the north piedmont of the Eagle and Hexie Mountains, each in turn overlain by successively younger residual and alluvial deposits. The Tertiary erosion surface is deformed and broken by north-northwest-trending, high-angle, dip-slip faults and an east-west trending system of high-angle dip- and left-slip faults. East-west trending faults are younger than and perhaps in part coeval with faults of the northwest-trending set. The Porcupine Wash database was created using ARCVIEW and ARC/INFO, which are geographical information system (GIS) software products of Envronmental Systems Research Institute (ESRI). The database consists of the following items: (1) a map coverage showing faults and geologic contacts and units, (2) a separate coverage showing dikes, (3) a coverage showing structural data, (4) a scanned topographic base at a scale of 1:24,000, and (5) attribute tables for geologic units (polygons and regions), contacts (arcs), and site-specific data (points). The database, accompanied by a pamphlet file and this metadata file, also includes the following graphic and text products: (1) A portable document file (.pdf) containing a navigable graphic of the geologic map on a 1:24,000 topographic base. The map is accompanied by a marginal explanation consisting of a Description of Map and Database Units (DMU), a Correlation of Map and Database Units (CMU), and a key to point-and line-symbols. (2) Separate .pdf files of the DMU and CMU, individually. (3) A PostScript graphic-file containing the geologic map on a 1:24,000 topographic base accompanied by the marginal explanation. (4) A pamphlet that describes the database and how to access it. Within the database, geologic contacts , faults, and dikes are represented as lines (arcs), geologic units as polygons and regions, and site-specific data as points. Polygon, arc, and point attribute tables (.pat, .aat, and .pat, respectively) uniquely identify each geologic datum and link it to other tables (.rel) that provide more detailed geologic information.

This data set maps and describes the geology of the Conejo Well 7.5 minute quadrangle, Riverside County, southern California. The quadrangle, situated in Joshua Tree National Park in the eastern Transverse Ranges physiographic and structural province, encompasses part of the northern Eagle Mountains and part of the south flank of Pinto Basin. It is underlain by a basement terrane comprising Proterozoic metamorphic rocks, Mesozoic plutonic rocks, and Mesozoic and Mesozoic or Cenozoic hypabyssal dikes. The basement terrane is capped by a widespread Tertiary erosion surface preserved in remnants in the Eagle Mountains and buried beneath Cenozoic deposits in Pinto Basin. Locally, Miocene basalt overlies the erosion surface.

The Tertiary erosion surface is deformed and broken by north-northwest-trending, high-angle, dip-slip faults in the Eagle Mountains and an east-west trending system of high-angle dip- and left-slip faults. In and adjacent to the Conejo Well quadrangle, faults of the northwest-trending set displace Miocene sedimentary rocks and basalt deposited on the Tertiary erosion surface and Pliocene and (or) Pleistocene deposits that accumulated on the oldest pediment. Faults of this system appear to be overlain by Pleistocene deposits that accumulated on younger pediments. East-west trending faults are younger than and perhaps in part coeval with faults of the northwest-trending set. The Conejo Well database was created using ARCVIEW and ARC/INFO, which are geographical information system (GIS) software products of Envronmental Systems Research Institute (ESRI).

THE NASA-UC ETA-EARTH PROGRAM. I. A SUPER-EARTH ORBITING HD 7924  

SciTech Connect

We report the discovery of the first low-mass planet to emerge from the NASA-UC Eta-Earth Program, a super-Earth orbiting the K0 dwarf HD 7924. Keplerian modeling of precise Doppler radial velocities reveals a planet with minimum mass M{sub P} sin i = 9.26 M {sub +} in a P = 5.398 d orbit. Based on Keck-HIRES measurements from 2001 to 2008, the planet is robustly detected with an estimated false alarm probability of less than 0.001. Photometric observations using the Automated Photometric Telescopes at Fairborn Observatory show that HD 7924 is photometrically constant over the radial velocity period to 0.19 mmag, supporting the existence of the planetary companion. No transits were detected down to a photometric limit of {approx}0.5 mmag, eliminating transiting planets with a variety of compositions. HD 7924b is one of only eight planets detected by the radial velocity technique with M{sub P} sin i < 10 M {sub +} and as such is a member of an emerging family of low-mass planets that together constrain theories of planet formation.

Examination of UC-ZrC after long term irradiation at thermionic temperature  

NASA Technical Reports Server (NTRS)

Two fluoride tungsten clad UC-ZrC fueled capsules, designated as V-2C and V-2D, were examined a hot cell after irradiation in NASA Plum Brook Reactor at a maximum cladding temperature of 1930 K for 11,089 and 12,031 hours to burnups of 3.0 x 10 to the 20th power and 2.1 x 10 to the 20th power fission/c.c. respectively. Percentage of fission gas release from the fuel material was measured by radiochemical means. Cladding deformation, fuel-cladding interaction and microstructures of fuel, cladding, and fuel-cladding interface were studied metallographically. Compositions of dispersions in fuel, fuel matrix and fuel-cladding interaction layer were analyzed by electron microprobe techniques. Axial and radial distributions of burnup were determined by gamma-scan, autoradiography and isotopic burnup analysis. The results are presented and discussed in conjunction with the requirements of thermionic fuel elements for space power application.

[Economic evaluation of social technologies applied to health promotion: water supply by the SODIS System in riverside communities of the Brazilian Amazon].  

PubMed

The so-called social technologies have been widely used in many places around the world as a viable alternative for low-income populations to gain access to opportunities for employment and income and other aspects related to quality of life, including basic sanitation. This paper conducts a cost-benefit analysis of using a low cost technology for drinking water used in several countries, namely the SODIS system. The study was conducted in riverside communities living in the island area of Belem municipality, located in the Brazilian Amazon. Data were collected through questionnaires answered by families living on three islands: Jutuba, Nova and Urubuoca. The results were positive, considering the cost-benefit analysis of the project, which demonstrates the economic viability of using the SODIS system in the situation investigated. PMID:23827916

Population Dynamics of Blood-Fed Female Mosquitoes and Comparative Efficacy of Resting Boxes in Collecting them from the Northwestern Part of Riverside County, California  

PubMed Central

Objectives: Testing of blood-fed mosquitoes plays an integral role in arbovirus surveillance and in understanding its interaction mechanisms between host, vector and reservoir. The present study was undertaken to evaluate the efficacy of two different traps (gravid and resting boxes) for collection of blood-fed mosquitoes in the northwestern part of Riverside County. Materials and Methods: Three trapping sites were selected in the Northwest Mosquito and Vector Control District of Riverside County, California. At each site resting boxes and gravid traps were set; and mosquitoes were collected on a weekly basis between July-December 2009. Mosquitoes were transported over blue ice, identified up to species level on chill table, and classified as male, female and blood-fed females. Results: During this study period, 3953 mosquitoes (826 blood-fed females) belonging to three different genera and eight species were collected; resting boxes collecting maximum number (seven) of mosquito species. Overall as well as individually in each trap kind, the most abundant mosquito species collected was Cx. quinquefasciatus. The proportion of blood-fed females of the Culex species collected in resting boxes was 28.8 times more, while of blood-fed females of Cx. quinquefasciatus was 32.2 times more than the proportion collected from gravid traps. Conclusions: Overall, the proportion of blood-fed female mosquitoes collected for each species trapped was highest in resting boxes. Additionally, resting boxes showed the advantage of extremely low running and maintenance cost; generation of no hazardous waste; quick turnaround time in terms of mosquito collection per man-hour spent; and they were less prone to vandalism or thefts.

Effect of glutathione depletion on UCO2 evolution from ( UC)methyl-labeled aminopyrine in intact rats  

SciTech Connect

The effect of hepatic glutathione depletion on UCO2 evolution from ( UC)methyl-labeled aminopyrine was assessed in fed male Sprague-Dawley rats. Within 30 min of i.p. administration of either diethylmaleate or phorone, hepatic glutathione fell approximately 75 to 80% and remained depressed for the ensuing 120 min. ( UC)Aminopyrine was i.p. administered 30 min after the glutathione-lowering agents (zero time) and exhaled UCO2 was collected at 15-min intervals for the next 120 min. Parameters of UCO2 exhalation including peak exhalation rate, cumulative exhalation from 0 to 120 min and the elimination rate constant were all impaired in glutathione-depleted rats. Metabolism of the ( UC)methyl groups involves N-demethylation with formation of formaldehyde, oxidation to formate and conversion to UCO2. Glutathione depletion did not affect CO2 evolution from i.p. administered formate or bicarbonate. The glutathione-dependent step presumably involves either or both generation of formaldehyde or its subsequent oxidation to formate.

Simulation of rice plant temperatures using the UC Davis Advanced Canopy-Atmosphere-Soil Algorithm (ACASA)  

NASA Astrophysics Data System (ADS)

The thermal environment in the plant canopy affects plants’ growth processes such as flowering and ripening. High temperatures often cause grain sterility and poor filling in serial crops, and reduce their production in tropical and temperate regions. With global warming predicted, these effects have become a major concern worldwide. In this study, we observed the plant body temperature profiles for the rice canopy and simulate them using a higher-order closure micrometeorological model to understand the relationship between plant temperatures and atmospheric condition. Experiments were conducted in rice paddy during 2007-summer season under warm temperate climate in Japan. Leaf temperatures at three different height (0.3, 0.5, 0.7m) and panicle temperatures at 0.9m were measured using fine-thermocouples. The UC Davis Advanced Canopy-Atmosphere-Soil Algorithm (ACASA) was used to calculate plant body temperature profiles in the canopy. ACASA is based on the radiation transfer, higher-order closure of turbulent equations for mass and heat exchange, and detailed plant physiological parameterization for the canopy-atmosphere-soil system. Water temperature was almost constant of 21-23 C throughout the summer because of continuous irrigation. Therefore, larger difference between air temperature at 2 m and water temperature was found on daytime. Observed leaf/panicle temperature was lower near the water surface and higher on upper layer in the canopy. Difference of temperatures between 0.3 m and 0.9 m was around 3-4 C for daytime, and around 1-2 C for nighttime. Calculated result of ACASA recreated these trends of plant temperature profile sufficiently. However, the relationship between plant and air temperature in the canopy was a little different from observed, i.e. observed leaf/panicle temperature were almost the same as air temperature, in contrast the simulated air temperature was 0.5-1.5 C higher than plant temperatures for the both of daytime and night time. This could be mainly due to the overestimation of latent heat flux in the day, and longwave cooling at night, although the precise reasons are unclear. ACASA can calculate the plant temperatures from given boundary condition, so that it is expected that it will elucidate how canopy structure (mainly leaf area index) affects thermal conditions in the canopy.

Undenatured type II collagen (UC-II(R)) for joint support: a randomized, double-blind, placebo-controlled study in healthy volunteers  

PubMed Central

Background UC-II contains a patented form of undenatured type II collagen derived from chicken sternum. Previous preclinical and clinical studies support the safety and efficacy of UC-II in modulating joint discomfort in osteoarthritis and rheumatoid arthritis. The purpose of this study was to assess the efficacy and tolerability of UC-II in moderating joint function and joint pain due to strenuous exercise in healthy subjects. Methods This randomized, double-blind, placebo-controlled study was conducted in healthy subjects who had no prior history of arthritic disease or joint pain at rest but experienced joint discomfort with physical activity. Fifty-five subjects who reported knee pain after participating in a standardized stepmill performance test were randomized to receive placebo (n?=?28) or the UC-II (40 mg daily, n?=?27) product for 120 days. Joint function was assessed by changes in degree of knee flexion and knee extension as well as measuring the time to experiencing and recovering from joint pain following strenuous stepmill exertion. Results After 120 days of supplementation, subjects in the UC-II group exhibited a statistically significant improvement in average knee extension compared to placebo (81.0?±?1.3º vs 74.0?±?2.2º; p?=?0.011) and to baseline (81.0?±?1.3º vs 73.2?±?1.9º; p?=?0.002). The UC-II cohort also demonstrated a statistically significant change in average knee extension at day 90 (78.8?±?1.9º vs 73.2?±?1.9º; p?=?0.045) versus baseline. No significant change in knee extension was observed in the placebo group at any time. It was also noted that the UC-II group exercised longer before experiencing any initial joint discomfort at day 120 (2.8?±?0.5 min, p?=?0.019), compared to baseline (1.4?±?0.2 min). By contrast, no significant changes were seen in the placebo group. No product related adverse events were observed during the study. At study conclusion, five individuals in the UC-II cohort reported no pain during or after the stepmill protocol (p?=?0.031, within visit) as compared to one subject in the placebo group. Conclusions Daily supplementation with 40 mg of UC-II was well tolerated and led to improved knee joint extension in healthy subjects. UC-II also demonstrated the potential to lengthen the period of pain free strenuous exertion and alleviate the joint pain that occasionally arises from such activities.

Identification of the Minimal Replicon of Lactococcus lactis subsp. lactis UC317 Plasmid pCI305  

PubMed Central

Replication functions of the stable, cryptic 8.7-kilobase (kb) plasmid pCI305 from multi-plasmid-containing Lactococcus lactis subsp. lactis UC317 were studied. Analysis of this replicon was facilitated by the construction of replication probe vectors that consisted of the pBR322 replication region, a pUC18-derived multiple cloning site, and either the cat gene of pC194 (pCI341; 3.1 kb) or the erm gene of pAM?1 (pCI3330; 4.0 kb). Plasmid pCI305 was introduced into plasmid-free L. lactis subsp. lactis MG1363Sm, a streptomycin-resistant derivative of MG1363, by a transformation procedure with the 75-kb lactose-proteinase plasmid pCI301 of UC317 as a marker plasmid. A combination of transposon Tn5 mutagenesis and subcloning in pCI341 and pCI3330 with individual Tn5 insertions around the replication region facilitated the identification of a 1.6-kb minimal replicon on pCI305. This region was separable into two domains: (i) a 1.3-kb region (repB) encoding a trans-acting function (in vitro transcription-translation studies suggested the involvement of a 48-kilodalton protein); and (ii) a 0.3-kb region (repA) sufficient to direct replication when provided with repB in trans and thus probably containing the origin of replication. Lactococcus-Escherichia coli shuttle vectors based on the pCI305 replication region were constructed. Images

Induction of the liver cancer-down-regulated long noncoding RNA uc002mbe.2 mediates trichostatin-induced apoptosis of liver cancer cells  

PubMed Central

Differential expression of long non-coding RNAs (lncRNAs) plays critical roles in hepatocarcinogenesis. Considerable attention has focused on the antitumor effect of histone deacetylase inhibitor (Trichostatin A, TSA) as well as the coding gene expression-induced apoptosis of cancer cells. However, it is not known whether lncRNA has a role in TSA-induced apoptosis of human hepatocellular carcinoma (HCC) cells. The global expression of lncRNAs and coding genes was analyzed with the Human LncRNA Array V2.0 after 24 h treatment. Expression was verified in cell lines and tissues by quantitative real-time PCR. The data showed that 4.8% (959) of lncRNA and 6.1% (1849) of protein coding gene were significantly differentially expressed. The differential expressions of lncRNA and protein coding genes had distinguishable hierarchical clustering expression profiling pattern. Among these differentially expressed lncRNAs, the greatest change was noted for uc002mbe.2, which had more than 300 folds induction upon TSA treatment. TSA selectively induced uc002mbe.2 in four studied HCC cell lines. Compared with normal human hepatocytes and adjacent noncancerous tissues, uc002mbe.2 expression level was significantly lower in the HCC cell lines and liver cancer tissues. The TSA-induced uc002mbe.2 expression was positively correlated with the apoptotic effect of TSA in HCC cells. In addition, knockdown the expression of uc002mbe.2 significantly reduced TSA-induced apoptosis of Huh7cells. Therefore, TSA-induced apoptosis of HCC cells is uc002mbe.2 dependent and reduced expression of uc002mbe.2 may be associated with liver carcinogenesis.

Geoelectric resistivity sounding of riverside alluvial aquifer in an agricultural area at Buyeo, Geum River watershed, Korea: an application to groundwater contamination study  

NASA Astrophysics Data System (ADS)

Twenty profiles of vertical electric soundings (VES) were obtained in a riverside alluvium at the Buyeo area, South Korea, to examine the variations of subsurface geology and associated groundwater chemistry. The combination of the VES data with the borehole data provided useful information on subsurface hydrogeologic conditions. The vestige of an ancient river channel (e.g. oxbow lake) was identified on the resistivity profiles by the lateral continuation of a near-surface perched aquifer parallel to the river. Such a perched aquifer is typically developed in the area with a clay-rich silty surface alluvium which prohibits the infiltration of oxygen. Therefore, groundwater below the oxbow lake shows a very low nitrate concentration and Eh values under the strong anoxic condition. The distribution of water resistivity is correlated with that of measured total dissolved solids concentration in groundwater, while the earth resistivity of the aquifer shows a significant spatial variation. It is interpreted that the earth resistivity of the aquifer is mainly controlled by the soil type rather than by the water chemistry in the study area.

Characterization of UC781-Tenofovir Combination Gel Products for HIV-1 Infection Prevention in an Ex Vivo Ectocervical Model  

PubMed Central

HIV continues to be a problem worldwide. Topical vaginal microbicides represent one option being evaluated to stop the spread of HIV. With drug candidates that have a specific action against HIV now being studied, it is important that, when appropriate and based on the mechanism of action, the drug permeates the tissue so that it can be delivered to specific targets which reside there. Novel formulations of the nucleotide reverse transcriptase inhibitor tenofovir (TFV) and the nonnucleoside reverse transcriptase inhibitor UC781 have been developed and evaluated here. Gels with three distinct rheological properties were prepared. The three gels released both UC781 and TFV under in vitro conditions at concentrations equal to or above the reported 50% effective concentrations (EC50s). The drug concentrations in ectocervical tissues were well in excess of the reported EC50s. The gels maintain ectocervical viability and prevent infection of ectocervical explants after a HIV-1 challenge. This study successfully demonstrates the feasibility of using this novel combination of antiretroviral agents in an aqueous gel as an HIV infection preventative.

Effects of defoliation in the developing leaf zone on young Populus Xeuramericana plants. II. Distribution of UC-photosynthate after defoliation  

SciTech Connect

Patterns of UC-photosynthate distribution in growth chamber-grown Populus xeuramericana cv. Negrito de Granada were determined 24 h, 3 weeks, and 5 weeks after defoliation in the developing leaf zone. Translocation patterns were determined by exposing leaves below, within, or above the defoliated zone to UCO2 and determining UC distribution within the plant after 48 h. Translocation patterns were altered within 24 h after defoliation. When leaves below or remaining tissue of leaves within the zone of defoliation were exposed to UCO2, a greater percentage of UC-photosynthate was transported to the expanding shoot and lateral branches and less to the roots in defoliated plants compared to controls. Little difference between defoliated and control plants and UC distribution occurred when new leaves produced subsequent to defoliation were exposed to UCO2. By 5 weeks after defoliation there was little difference in patterns of UC distribution between defoliated and control plants. These results substantiate biomass partitioning data which showed that a single defoliation of young poplar plants did not affect diameter or height growth, whereas leaf growth was stimulated and root growth reduced.

A New Bioinformatics Approach to Analyze Gene Expressions and Signaling Pathways Reveals Unique Purine Gene Dysregulation Profiles that Distinguish between CD and UC  

PubMed Central

Expression of purine genes is modulated by inflammation or experimental colitis and altered expression leads to disrupted gut function. We studied purine gene dysregulation profiles in IBD and determined whether they can distinguish between CD and UC using Pathway Analysis and a new Comparative Analysis of Gene Expression and Selection (CAGES) method. Raw datasets for 22 purine genes and 36 probe-sets from NCBI GEO (http://www.ncbi.nlm.nih.gov/ projects /geo/) were analyzed by NCI BRB array tools for random-variance of multiple/36 t-tests in colonic mucosal biopsies or PBMCs of CD, UC or control subjects. Dysregulation occurs in 59% of purine genes in IBD including ADORA3,CD73, ADORA2A,ADORA2B,ADAR,AMPD2,AMPD3,DPP4, P2RY5,P2RY6,P2RY13,P2RY14 and P2RX5. In CD biopsies, expression of ADORA3,AMPD3,P2RY13 and P2RY5 were negatively correlated with acute inflammatory score, CDAI or disease chronicity;P2RY14 was positively correlated in UC. In mucosal biopsies or PBMCs, CD and UC were distinguished by unique patterns of dysregulation (up- or down-regulation) in purine genes. Purine gene dysregulation differs between PBMCs and biopsies and possibly between sexes for each disease. Ingenuity pathway analysis (IPA) revealed significant associations between alterations in the expression of CD73 (upregulation) or ADORA3 (downregulation) and inflammatory or purine genes (?10% of 57 genes) as well as GPCR, cAMP-dependent and inflammatory pathways; IPA distinguishes CD from UC. In conclusion, CAGES and Pathway Analysis provided novel evidence that UC and CD have distinct purine gene dysregulation signatures in association with inflammation, cAMP or other signaling pathways. Disease-specific purine gene signature profiles and pathway associations may be of therapeutic, diagnostic and functional relevance.

Development of a Real-Time GPS/Seismic Displacement Meter: Applications to Civilian Infrastructure in Orange and Western Riverside Counties, California  

NASA Technical Reports Server (NTRS)

We propose a three-year applications project that will develop an Integrated Real-Time GPS/Seismic System and deploy it in Orange and Western Riverside Counties, spanning three major strike-slip faults in southern California (San Andreas, San Jacinto, and Elsinore) and significant populations and civilian infrastructure. The system relying on existing GPS and seismic networks will collect and analyze GPS and seismic data for the purpose of estimating and disseminating real-time positions and total ground displacements (dynamic, as well as static) during all phases of the seismic cycle, from fractions of seconds to years. Besides its intrinsic scientific use as a real-time displacement meter (transducer), the GPS/Seismic System will be a powerful tool for local and state decision makers for risk mitigation, disaster management, and structural monitoring (dams, bridges, and buildings). Furthermore, the GPS/Seismic System will become an integral part of California's spatial referencing and positioning infrastructure, which is complicated by tectonic motion, seismic displacements, and land subsidence. Finally, the GPS/Seismic system will also be applicable to navigation in any environment (land, sea, or air) by combining precise real-time instantaneous GPS positioning with inertial navigation systems. This development will take place under the umbrella of the California Spatial Reference Center, in partnership with local (Counties, Riverside County Flood and Water Conservation District, Metropolitan Water District), state (Caltrans), and Federal agencies (NGS, NASA, USGS), the geophysics community (SCIGN/SCEC2), and the private sector (RBF Consulting). The project will leverage considerable funding, resources, and R&D from SCIGN, CSRC and two NSF-funded IT projects at UCSD and SDSU: RoadNet (Real-Time Observatories, Applications and Data Management Network) and the High Performance Wireless Research and Education Network (HPWREN). These two projects are funded to develop both the wireless networks and the integrated, seamless, and transparent information management system that will deliver seismic, geodetic, oceanographic, hydrological, ecological, and physical data to a variety of end users in real-time in the San Diego region. CSRC is interested in providing users access to real-time, accurate GPS data for a wide variety of applications including RTK surveying/GIS and positioning of moving platforms such as aircraft and emergency vehicles. SCIGN is interested in upgrading sites to high-frequency real-time operations for rapid earthquake response and GPS seismology. The successful outcome of the project will allow the implementation of similar systems elsewhere, particularly in plate boundary zones with significant populations and civilian infrastructure. CSRC would like to deploy the GPS/Seismic System in other parts of California, in particular San Diego, Los Angeles County and the San Francisco Bay Area.

Evaluation of toxic effects of a diet containing fish contaminated with methylmercury in rats mimicking the exposure in the Amazon riverside population.  

PubMed

This study was designed to evaluate the effects of a diet rich in fish contaminated with MeHg, mimicking the typical diet of the Amazon riverside population, in rats. Animals were randomly assigned to one of three groups with eight rats in each group: Group I-control, received commercial ration; Group II-received a diet rich in uncontaminated fish; Group III-received a diet rich in fish contaminated with MeHg. Treatment time was 12 weeks. Oxidative stress markers were evaluated, as well as the effects of this diet on DNA stability, systolic blood pressure (SBP), nitric oxide (NO) levels and histological damage in different tissues. There was a significant increase in SBP values in rats fed with MeHg-contaminated fish diet after the 10th week of the treatment. As far as oxidative stress biomarkers are concerned, no differences were observed in reduced glutathione and protein carbonyl levels, glutathione peroxidase, catalase, superoxide dismutase or ?-aminolevulinate dehydratase activities between the groups of animals receiving contaminated and uncontaminated fish diets. On the other hand, malondialdehyde levels increased significantly in rats fed with contaminated fish. NO levels were similar in all groups. DNA migration showed augmented in rats exposed to contaminated fish and histopathological analyses showed weak but significant leukocyte infiltration. Thus, we conclude that the MeHg-contaminated fish diet induced a slight lipid peroxidation and genotoxicity. However, these effects seem to be much less pronounced than when rats are exposed to aqueous solution containing CH3HgCl. Our findings support the contention that the chemical form of MeHg in fish or fish nutrients such as polyunsaturated fatty acids, Se or vitamin E could minimize the toxic effects of MeHg exposure in fish-eating communities.

Does the cortical bone resorption rate change due to 90Sr-radiation exposure? Analysis of data from Techa Riverside residents  

SciTech Connect

The Mayak Production Association released large amounts of 90Sr into the Techa River (Southern Urals, Russia) with peak amounts in 1950-1951. Techa Riverside residents ingested an average of about 3,000 kBq of 90Sr. The 90Sr-body burden of approximately 15,000 individuals has been measured in the Urals Research Center for Radiation Medicine in 1974-1997 with use of a special whole-body counter (WBC). Strontium-90 had mainly deposited in the cortical part of the skeleton by 25 years following intake, and 90Sr elimination occurs as a result of cortical bone resorption. The effect of 90Sr-radiation exposure on the rate of cortical bone resorption was studied. Data on 2,022 WBC measurements were selected for 207 adult persons, who were measured three or more times before they were 50-55 years old. The individual-resorption rates were calculated with the rate of strontium recirculation evaluated as 0.0018 year?1. Individual absorbed doses in red bone marrow (RBM) and bone surface (BS) were also calculated. Statistically significant negative relationships of cortical bone resorption rate were discovered related to 90Sr-body burden and dose absorbed in the RBM or the BS. The response appears to have a threshold of about 1.5-Gy RBM dose. The radiation induced decrease in bone resorption rate may not be significant in terms of health. However, a decrease in bone remodeling rate can be among several causes of an increased level of degenerative dystrophic bone pathology in exposed persons.

Production of spherical UO/sub 2/-UC/sub 2/ for nuclear fuel applications using thermochemical principles  

SciTech Connect

A process for the fabrication of uranium dioxide-uranium dicarbide microspheres for use as an advanced nuclear fuel is described. The uranium-carbon-oxygen phase diagram was used extensively in applying thermochemical principles to the combined process of uranium carbide synthesis and kernel sintering. Variation of the partial pressure of carbon monoxide during the carbothermic reduction of urania plus carbon allowed the kernel composition and density to be controlled. X-ray diffraction, microstructural examination, and detailed chemical analyses were used to identify the kernel composition. A procedure was developed to convert urania plus carbon microspheres produced by a wet-chemical gelation process to a highly dense UO/sub 2/-UC/sub 2/ product at 1550/sup 0/C.

Preparation of UC0.07-0.10N0.90-0.93 spheres for TRISO coated fuel particles  

SciTech Connect

The U.S. Department of Energy is considering a new nuclear fuel, which should be much more impervious during a loss of coolant accident. The fuel would consist of tristructural isotropic coated particles with dense uranium nitride (UN) kernels. The objectives of this effort are to make uranium oxide microspheres with adequately dispersed carbon nanoparticles and to convert these microspheres into UN kernels. Recent improvements to internal gelation process were successfully applied to the production of uranium gel spheres with different concentrations of carbon black. After the spheres were washed, a simple, two-step heat profile was used to produce kernels with a chemical composition of UC0.07 0.10N0.90 0.93. The first step involved heating the microspheres to 2023 K in a vacuum, and in the second step, the microspheres were held at 1873 K for 6 hrs in nitrogen.

The use of the percentile method for searching empirical relationships between compression strength (UCS), Point Load (Is50) and Schmidt Hammer (RL) Indices  

NASA Astrophysics Data System (ADS)

Is50 and RL indices are commonly used to indirectly estimate the compression strength of a rocky deposit by in situ and in laboratory devices. The widespread use of Point load and Schmidt hammer tests is due to the simplicity and the speediness of the execution of these tests. Their indices can be related to the UCS by means of the ordinary least square regression analyses. Several researchers suggest to take into account the lithology to build high correlated empirical expressions (R2 >0.8) to draw UCS from Is50 or RL values. Nevertheless, the lower and upper bounds of the UCS ranges of values that can be estimated by means of the two indirect indices are not clearly defined yet. Aydin (2009) stated that the Schmidt hammer test shall be used to assess the compression resistance of rocks characterized by UCS>12-20 MPa. On the other hand, the Point load measures can be performed on weak rocks but upper bound values for UCS are not suggested. In this paper, the empirical relationships between UCS, RL and Is50 are searched by means of the percentile method (Bruno et al. 2013). This method is based on looking for the best regression function, between measured data of UCS and one of the indirect indices, drawn from a subset sample of the couples of measures that are the percentile values. These values are taken from the original dataset of both measures by calculating the cumulative function. No hypothesis on the probability distribution of the sample is needed and the procedure shows to be robust with respect to odd values or outliers. In this study, the carbonate sedimentary rocks are investigated. According to the rock mass classification of Dobereiner and De Freitas (1986), the UCS values for the studied rocks range between 'extremely weak' to 'strong'. For the analyzed data, UCS varies between 1,18-270,70 MPa. Thus, through the percentile method the best empirical relationships UCS-Is50 and UCS-RL are plotted. Relationships between Is50 and RL are drawn, too. Finally, the goodness of the plotted empirical expressions have been checked through couples of measures selected from the original dataset and not used to search for the empirical relationships.

First Phase 1 Double-Blind, Placebo-Controlled, Randomized Rectal Microbicide Trial Using UC781 Gel with a Novel Index of Ex Vivo Efficacy  

PubMed Central

Objectives Successful control of the HIV/AIDS pandemic requires reduction of HIV-1 transmission at sexually-exposed mucosae. No prevention studies of the higher-risk rectal compartment exist. We report the first-in-field Phase 1 trial of a rectally-applied, vaginally-formulated microbicide gel with the RT-inhibitor UC781 measuring clinical and mucosal safety, acceptability and plasma drug levels. A first-in-Phase 1 assessment of preliminary pharmacodynamics was included by measuring changes in ex vivo HIV-1 suppression in rectal biopsy tissue after exposure to product in vivo. Methods HIV-1 seronegative, sexually-abstinent men and women (N?=?36) were randomized in a double-blind, placebo-controlled trial comparing UC781 gel at two concentrations (0.1%, 0.25%) with placebo gel (1?1?1). Baseline, single-dose exposure and a separate, 7-day at-home dosing were assessed. Safety and acceptability were primary endpoints. Changes in colorectal mucosal markers and UC781 plasma drug levels were secondary endpoints; ex vivo biopsy infectibility was an ancillary endpoint. Results All 36 subjects enrolled completed the 7–14 week trial (100% retention) including 3 flexible sigmoidoscopies, each with 28 biopsies (14 at 10 cm; 14 at 30 cm). There were 81 Grade 1 adverse events (AEs) and 8 Grade 2; no Grade 3, 4 or procedure-related AEs were reported. Acceptability was high, including likelihood of future use. No changes in mucosal immunoinflammatory markers were identified. Plasma levels of UC781 were not detected. Ex vivo infection of biopsies using two titers of HIV-1BaL showed marked suppression of p24 in tissues exposed in vivo to 0.25% UC781; strong trends of suppression were seen with the lower 0.1% UC781 concentration. Conclusions Single and 7-day topical rectal exposure to both concentrations of UC781 were safe with no significant AEs, high acceptability, no detected plasma drug levels and no significant mucosal changes. Ex vivo biopsy infections demonstrated marked suppression of HIV infectibility, identifying a potential early biomarker of efficacy. (Registered at ClinicalTrials.gov; #NCT00408538)

With the aim of studying the interface magnetism, the onset of ferromagnetism and the onset of the transition to the superconducting state a series of [La0.7Sr0.3MnO3(n u.c.)/YBa2Cu3O7(2 u.c.)]20 (LSMO/YBCO) superlattices with nominally varying layer thickness of the LSMO from one to four unit cells (u.c.) was prepared and characterized by x-ray diffraction, electronic transport, magnetization and ferromagnetic resonance measurements. Spontaneous magnetization was observed for a superlattice with four u.c. LSMO layer thickness in a multilayer structure. Superlattices with 3 u.c. of LSMO and lower layer thicknesses did not show a signature of ferromagnetism. The onset of superconductivity was observed for superlattices with one and two LSMO layer u.c. thickness.

A change in temperature modulates defence to yellow (stripe) rust in wheat line UC1041 independently of resistance gene Yr36  

PubMed Central

Background Rust diseases are of major importance in wheat production worldwide. With the constant evolution of new rust strains and their adaptation to higher temperatures, consistent and durable disease resistance is a key challenge. Environmental conditions affect resistance gene performance, but the basis for this is poorly understood. Results Here we show that a change in day temperature affects wheat resistance to Puccinia striiformis f. sp tritici (Pst), the causal agent of yellow (or stripe) rust. Using adult plants of near-isogenic lines UC1041 +/- Yr36, there was no significant difference between Pst percentage uredia coverage in plants grown at day temperatures of 18°C or 25°C in adult UC1041?+?Yr36 plants. However, when plants were transferred to the lower day temperature at the time of Pst inoculation, infection increased up to two fold. Interestingly, this response was independent of Yr36, which has previously been reported as a temperature-responsive resistance gene as Pst development in adult UC1041 -Yr36 plants was similarly affected by the plants experiencing a temperature reduction. In addition, UC1041 -Yr36 plants grown at the lower temperature then transferred to the higher temperature were effectively resistant and a temperature change in either direction was shown to affect Pst development up to 8 days prior to inoculation. Results for seedlings were similar, but more variable compared to adult plants. Enhanced resistance to Pst was observed in seedlings of UC1041 and the cultivar Shamrock when transferred to the higher temperature. Resistance was not affected in seedlings of cultivar Solstice by a temperature change in either direction. Conclusions Yr36 is effective at 18°C, refining the lower range of temperature at which resistance against Pst is conferred compared to previous studies. Results reveal previously uncharacterised defence temperature sensitivity in the UC1041 background which is caused by a change in temperature and independently of Yr36. This novel phenotype is present in some cultivars but absent in others, suggesting that Pst defence may be more stable in some cultivars than others when plants are exposed to varying temperatures.

An uc(l)-Arginine supplement improves broiler hypertensive response and gut function in broiler chickens reared at high altitude  

NASA Astrophysics Data System (ADS)

An experiment was carried out to examine the effects of supplemental dietary arginine (ARG) on growth, hypertensive response, and gut function in broilers reared at high altitude (2,100 m). A total of 120 day-old male broilers (Cobb 500) were divided equally into two treatment groups. Treatments included a control basal diet composed of corn and soybean meal and an experimental diet to which an uc(l)-ARG supplement was added at 10 g/kg. The trial lasted for 42 days. There were no treatment differences with regard to feed intake, body weight gain, or feed conversion ratio. However ARG supplementation did increase the plasma concentration of nitric oxide, a potent vasodilator (P < 0.05), and attenuated indices of pulmonary hypertension as reflected by reductions in the hematocrit and the right to total ventricular weight ratio (P < 0.05). Significantly enhanced intestinal mucosal development was observed in broilers receiving ARG supplement when compared with controls (P < 0.05), suggesting that ARG supplementation increased the absorptive surface area of the jejunum and ileum. In conclusion, broiler diets supplemented with ARG beneficially improved pulmonary hemodynamics and appeared to enhance gut function.

The UC-LLNL Regional Climate System Model (RCSM) has been under development since 1991. This modeling system includes interactions among atmospheric, land surface, and subsurface processes. Important physical processes included in this RCSM are effects of vegetation, surface energy and water budgets, lateral hydrologic transport, and agro-ecosystem response. Our RCSM is composed of a preprocessor fro importing, interpreting, and analyzing multi-scale data, a Mesoscale Atmospheric Simulation (MAS) model, a multi-layer soil-plant-snow (SPS) model that is interactively coupled with the atmospheric model, a physically based, fully distributed watershed hydrology-riverflow model (TOPMODEL) and a post-processor for output data analysis. We are currently implementing and validating the Decision Support System for Agro-Economic Transfer (DSSAT). An important feature of our RCSM us the ability to simulate the atmospheric, land surface, and hydrologic variables from the global scale down to the watershed catchment scale. the full coupled MAS and SPS models have been used for experimental operational NWP over the southwestern United States since October 1993. Our watershed hydrology-riverflow model has been set up for the Russian River watershed and the Headwaters to the North Fork of the American River in Northern California.

The objectives of this effort are to make uranium oxide microspheres with adequately dispersed carbon nanoparticles and to convert these microspheres into UN spheres, which could be then sintered into kernels. Recent improvements to the internal gelation process were successfully applied to the production of uranium gel spheres with different concentrations of carbon black. After the spheres were washed and dried, a simple two-step heat profile was used to produce porous microspheres with a chemical composition of UC0.07-0.10N0.90-0.93. The first step involved heating the microspheres to 2023 K in a vacuum, and in the second step, the microspheres were held at 1873 K for 6 h in flowing nitrogen.

Rainfall-runoff characteristics and effects of increased urban density on streamflow and infiltration in the eastern part of the San Jacinto River basin, Riverside County, California  

USGS Publications Warehouse

To better understand the rainfall-runoff characteristics of the eastern part of the San Jacinto River Basin and to estimate the effects of increased urbanization on streamflow, channel infiltration, and land-surface infiltration, a long-term (1950?98) time series of monthly flows in and out of the channels and land surfaces were simulated using the Hydrologic Simulation Program- FORTRAN (HSPF) rainfall-runoff model. Channel and land-surface infiltration includes rainfall or runoff that infiltrates past the zone of evapotranspiration and may become ground-water recharge. The study area encompasses about 256 square miles of the San Jacinto River drainage basin in Riverside County, California. Daily streamflow (for periods with available data between 1950 and 1998), and daily rainfall and evaporation (1950?98) data; monthly reservoir storage data (1961?98); and estimated mean annual reservoir inflow data (for 1974 conditions) were used to calibrate the rainfall-runoff model. Measured and simulated mean annual streamflows for the San Jacinto River near San Jacinto streamflow-gaging station (North-South Fork subbasin) for 1950?91 and 1997?98 were 14,000 and 14,200 acre-feet, respectively, a difference of 1.4 percent. The standard error of the mean for measured and simulated annual streamflow in the North-South Fork subbasin was 3,520 and 3,160 acre-feet, respectively. Measured and simulated mean annual streamflows for the Bautista Creek streamflow-gaging station (Bautista Creek subbasin) for 1950?98 were 980 acre-feet and 991 acre-feet, respectively, a difference of 1.1 percent. The standard error of the mean for measured and simulated annual streamflow in the Bautista Creek subbasin was 299 and 217 acre-feet, respectively. Measured and simulated annual streamflows for the San Jacinto River above State Street near San Jacinto streamflow-gaging station (Poppet subbasin) for 1998 were 23,400 and 23,500 acre-feet, respectively, a difference of 0.4 percent. The simulated mean annual streamflow for the State Street gaging station at the outlet of the study basin and the simulated mean annual basin infiltration (combined infiltration from all the channels and land surfaces) were 8,720 and 41,600 acre-feet, respectively, for water years 1950-98. Simulated annual streamflow at the State Street gaging station ranged from 16.8 acre-feet in water year 1961 to 70,400 acre-feet in water year 1993, and simulated basin infiltration ranged from 2,770 acre-feet in water year 1961 to 149,000 acre-feet in water year 1983.The effects of increased urbanization on the hydrology of the study basin were evaluated by increasing the size of the effective impervious and non-effective impervious urban areas simulated in the calibrated rainfall-runoff model by 50 and 100 percent, respectively. The rainfall-runoff model simulated a long-term time series of monthly flows in and out of the channels and land surfaces using daily rainfall and potential evaporation data for water years 1950?98. Increasing the effective impervious and non-effective impervious urban areas by 100 percent resulted in a 5-percent increase in simulated mean annual streamflow at the State Street gaging station, and a 2.2-percent increase in simulated basin infiltration. Results of a frequency analysis of the simulated annual streamflow at the State Street gaging station showed that when effective impervious and non-effective impervious areas were increased 100 percent, simulated annual streamflow increased about 100 percent for low-flow conditions and was unchanged for high-flow conditions. The simulated increase in streamflow at the State Street gaging station potentially could infiltrate along the stream channel further downstream, outside of the model area.

Biotransformation of primary nicotine metabolites. I. In vivo metabolism of R-(+)-( UC-NCH3)N-methylnicotinium ion in the guinea pig  

SciTech Connect

The in vivo biotransformation and tissue distribution of the methylated nicotine metabolite R-(+)-( UC-NCH3)N-methylnicotinium acetate was studied in the guinea pig. The detection and quantification of 24-hr urinary metabolites after ip injection was determined by cation-exchange HPLC interfaced to a radiochemical flowthrough detector. The urinary metabolite profile consisted of five peaks. One eluted close to the void, and three coeluted with authentic standards of N-methylcotininium ion, N-methylnornicotinium ion, and N-methylnicotinium ion. A fifth, and as yet unidentified, metabolite was also detected. Tissue distribution of UC label after 24 hr was highest in the adrenal gland and epididymis followed by the gallbladder, bladder, kidney, spleen, and heart. No significant amounts of UC were found in the brain. The results indicate that N-methylcotininium ion and N-methylnornicotinium ion are both formed subsequent to the formation of N-methylnicotinium ion in the metabolism of R-(+)-nicotine in the guinea pig.

Uridine Composition of the Poly-U/UC Tract of HCV RNA Defines Non-Self Recognition by RIG-I  

PubMed Central

Viral infection of mammalian cells triggers the innate immune response through non-self recognition of pathogen associated molecular patterns (PAMPs) in viral nucleic acid. Accurate PAMP discrimination is essential to avoid self recognition that can generate autoimmunity, and therefore should be facilitated by the presence of multiple motifs in a PAMP that mark it as non-self. Hepatitis C virus (HCV) RNA is recognized as non-self by RIG-I through the presence of a 5?-triphosphate (5?-ppp) on the viral RNA in association with a 3? poly-U/UC tract. Here we define the HCV PAMP and the criteria for RIG-I non-self discrimination of HCV by examining the RNA structure-function attributes that impart PAMP function to the poly-U/UC tract. We found that the 34 nucleotide poly-uridine “core” of this sequence tract was essential for RIG-I activation, and that interspersed ribocytosine nucleotides between poly-U sequences in the RNA were required to achieve optimal RIG-I signal induction. 5?-ppp poly-U/UC RNA variants that stimulated strong RIG-I activation efficiently bound purified RIG-I protein in vitro, and RNA interaction with both the repressor domain and helicase domain of RIG-I was required to activate signaling. When appended to 5?-ppp RNA that lacks PAMP activity, the poly-U/UC U-core sequence conferred non-self recognition of the RNA and innate immune signaling by RIG-I. Importantly, HCV poly-U/UC RNA variants that strongly activated RIG-I signaling triggered potent anti-HCV responses in vitro and hepatic innate immune responses in vivo using a mouse model of PAMP signaling. These studies define a multi-motif PAMP signature of non-self recognition by RIG-I that incorporates a 5?-ppp with poly-uridine sequence composition and length. This HCV PAMP motif drives potent RIG-I signaling to induce the innate immune response to infection. Our studies define a basis of non-self discrimination by RIG-I and offer insights into the antiviral therapeutic potential of targeted RIG-I signaling activation.

Geology, ground-water hydrology, geochemistry, and ground-water simulation of the Beaumont and Banning Storage Units, San Gorgonio Pass area, Riverside County, California  

USGS Publications Warehouse

Ground water has been the only source of potable water supply for residential, industrial, and agricultural users in the Beaumont and Banning storage units of the San Gorgonio Pass area, Riverside County, California. Ground-water levels in the Beaumont area have declined as much as 100 feet between the early 1920s and early 2000s, and numerous natural springs have stopped flowing. In 1961, the San Gorgonio Pass Water Agency (SGPWA) entered into a contract with the California State Department of Water Resources to receive 17,300 acre-feet per year of water to be delivered by the California State Water Project (SWP) to supplement natural recharge. Currently (2005), a pipeline is delivering SWP water into the area, and the SGPWA is artificially recharging the ground-water system using recharge ponds located along Little San Gorgonio Creek in Cherry Valley with the SWP water. In addition to artificial recharge, SGPWA is considering the direct delivery of SWP water for the irrigation of local golf courses and for agricultural supply in lieu of ground-water pumpage. To better understand the potential hydrologic effects of different water-management alternatives on ground-water levels and movement in the Beaumont and Banning storage units, existing geohydrologic and geochemical data were compiled, new data from a basin-wide ground-water level and water-quality monitoring network were collected, monitoring wells were installed near the Little San Gorgonio Creek recharge ponds, geohydrologic and geochemical analyses were completed, and a ground-water flow simulation model was developed. The San Gorgonio Pass area was divided into several storage units on the basis of mapped or inferred faults. This study addresses primarily the Beaumont and Banning storage units. The geologic units in the study area were generalized into crystalline basement rocks and sedimentary deposits. The younger sedimentary deposits and the surficial deposits are the main water-bearing deposits in the San Gorgonio Pass area. The water-bearing deposits were divided into three aquifers: (1) the perched aquifer, (2) the upper aquifer, and (3) the lower aquifer based on lithologic and downhole geophysical logs. Natural recharge in the San Gorgonio Pass area was estimated using INFILv3, a deterministic distributed- parameter precipitation-runoff model. The INFILv3 model simulated that the potential recharge of precipitation and runoff in the Beaumont and Banning storage units was about 3,710 acre-feet per year and that the potential recharge in 28 sub-drainage basins upstream of the storage units was about 6,180 acre-feet per year. The water supply for the Beaumont and Banning storage units is supplied by pumping ground water from wells in the Canyon (Edgar and Banning Canyons), Banning Bench, Beaumont, and Banning storage units. Total annual pumpage from the Beaumont and Banning storage units ranged from about 1,630 acre-feet in 1936 to about 20,000 acre-feet in 2003. Ground-water levels declined by as much as 100 feet in the Beaumont storage unit from 1926-2003 in response to ground-water pumping of about 450,160 acre-feet during this period. Since ground-water development began in the San Gorgonio Pass area, there have been several sources of artificial recharge to the basin including return flow from applied water on crops, golf courses, and landscape; septic-tank seepage; and infiltration of storm runoff diversions and imported water into recharge ponds. Return flow from applied water and septic-tank seepage was estimated to reach a maximum of about 8,100 acre-feet per year in 2003. Owing to the great depth of water in much of study area (in excess of 150 feet), the return flow and septic-tank seepage takes years to decades to reach the water table. Stable-isotope data indicate that the source of ground-water recharge was precipitation from storms passing through the San Gorgonio Pass as opposed to runoff from the higher altitudes of the San Bernar

Coupling XRD, EXAFS, and 13C NMR to study the effect of the carbon stoichiometry on the local structure of UC(1±x).  

PubMed

A series of uranium carbide samples, prepared by arc melting with a C/U ratio ranging from 0.96 to 1.04, has been studied by X-ray diffraction (XRD), (13)C nuclear magnetic resonance (NMR), and extended X-ray absorption fine structure (EXAFS). XRD determines phase uniqueness and the increase of the lattice parameter versus the carbon content. In contrast, (13)C NMR detects the different carbon environments in the lattice and in this study, clearly identifies the presence of discrete peaks for carbon in the octahedral lattice site in UC and an additional peak associated with excess carbon in hyperstoichiometric samples. Two peaks associated with different levels of carbon deficiency are detected for all hypostoichiometric compositions. More than one carbon environment is always detected by (13)C NMR. This exemplifies the difficulty in obtaining a perfect stoichiometric uranium monocarbide UC(1.00). The (13)C MAS spectra of uranium carbides exhibit the effects resulting from the carbon content on both the broadening of the peaks and on the Knight shift. An abrupt spectral change occurs between hypo- and hyperstoichiometric samples. The results obtained by EXAFS highlight subtle differences between the different stoichiometries, and in the hyperstoichiometric samples, the EXAFS results are consistent with the excess carbon atoms being in the tetrahedral interstitial position.

PubMed

UC CEIN was established with funding from the US National Science Foundation and the US Environmental Protection Agency in 2008 with the mission to study the impact of nanotechnology on the environment, including the identification of hazard and exposure scenarios that take into consideration the unique physicochemical properties of engineered nanomaterials (ENMs). Since its inception, the Center has made great progress in assembling a multidisciplinary team to develop the scientific underpinnings, research, knowledge acquisition, education and outreach that is required for assessing the safe implementation of nanotechnology in the environment. In this essay, the development of the infrastructure, protocols, and decision-making tools that are required to effectively integrate complementary scientific disciplines allowing knowledge gathering in a complex study area that goes beyond the traditional safety and risk assessment protocols of the 20th century is outlined. UC CEIN's streamlined approach, premised on predictive hazard and exposure assessment methods, high-throughput discovery platforms and environmental decision-making tools that consider a wide range of nano/bio interfaces in terrestrial and aquatic ecosystems, demonstrates the implementation of a 21st-century approach to the safe implementation of nanotechnology in the environment.

[Status of hemapoiesis in residents of the Techa riverside villages in the period of maximum radiation exposure. Report 1. Evaluation of the cellular composition of peripheral blood and the role of comorbidities in the oppression of hemapoiesis].  

PubMed

Residents of the Techa riverside villages chronically exposed to ionizing radiation (the average dose rate in 1951-1956 was 0.047 Gy/year, the maximum reached 2.44 Gy/year) developed marked changes in the cellular composition of peripheral blood. The maximum reduction of peripheral blood counts occurred in the years 1951-1953, after which the beginning of the restoration of cellularity to the control level was observed. The dose rate at this point (1956) was about 0.02 Gy/year. The factors of radiation and non-radiation nature (gender, the age at the onset of exposure, health related disorders) in different combinations affect the number of peripheral blood cells. The influence of dose rate of a chronic radiation exposure on a platelet count takes precedence over other factors. The factors of gender and dose rate determine the number of erythrocytes in exposed persons. The changes accompanying the health status and dose rate significantly affect the number of neutrophils. The influence of comorbidity, age and dose rate on the number of monocytes was noted. A lymphocyte count was mainly determined by the age at the onset of exposure and concomitant diseases. A joint influence of chronic radiation exposure and concomitant diseases increases a mutual action on erythro- and thrombocytopoiesis. The decrease of the dose rate was followed by a gradual predominance of the somatic disease influence on leukocyte (neutrophils, lymphocytes and monocytes) counts. PMID:22690574

Analytical results and sample locality map for rock, stream-sediment, and soil samples, Northern and Eastern Coloado Desert BLM Resource Area, Imperial, Riverside, and San Bernardino Counties, California  

USGS Publications Warehouse

INTRODUCTION In 1996-1998 the U.S. Geological Survey (USGS) conducted a geochemical study of the Bureau of Land Management's (BLM) 5.5 million-acre Northern and Eastern Colorado Desert Resource Area (usually referred to as the NECD in this report), Imperial, Riverside, and San Bernardino Counties, southeastern California (figure 1). This study was done in support of the BLM's Coordinated Management Plan for the area. This report presents analytical data from this study. To provide comprehensive coverage of the NECD, we compiled and examined all available geochemical data, in digital form, from previous studies in the area, and made sample-site plots to aid in determining where sample-site coverage and analyses were sufficient, which samples should be re-analyzed, and where additional sampling was needed. Previous investigations conducted in parts of the current study area included the National Uranium Resource Evaluation (NURE) program studies of the Needles and Salton Sea 1? x 2? quadrangles; USGS studies of 12 BLM Wilderness Study Areas (WSAs) (Big Maria Mountains, Chemehuevi Mountains, Chuckwalla Mountains, Coxcomb Mountains, Mecca Hills, Orocopia Mountains, Palen-McCoy, Picacho Peak, Riverside Mountains, Sheephole Valley (also known as Sheep Hole/Cadiz), Turtle Mountains, and Whipple Mountains); and USGS studies in the Needles and El Centro 1? x 2? quadrangles done during the early 1990s as part of a project to identify the regional geochemistry of southern California. Areas where we did new sampling of rocks and stream sediments are mainly in the Chocolate Mountain Aerial Gunnery Range and in Joshua Tree National Park, which extends into the west-central part of the NECD, as shown in figure 1 and figure 2. This report contains analytical data for 132 rock samples and 1,245 stream-sediment samples collected by the USGS, and 362 stream-sediment samples and 189 soil samples collected during the NURE program. All samples are from the Northern and Eastern Colorado Desert BLM Resource Area and vicinity. Included in the 1,245 stream-sediment samples collected by the USGS are 284 samples collected as part of the current study, 817 samples collected as part of investigations of the12 BLM WSAs and re-analyzed for the present study, 45 samples from the Needles 1? X 2? quadrangle, and 99 samples from the El Centro 1? X 2? quadrangle. The NURE stream-sediment and soil samples were re-analyzed as part of the USGS study in the Needles quadrangle. Analytical data for samples from the Chocolate Mountain Aerial Gunnery Range, which is located within the area of the NECD, were previously reported (King and Chaffee, 1999a). For completeness, these results are also included in this report. Analytical data for samples from the area of Joshua Tree National Park that is within the NECD have also been reported (King and Chaffee, 1999b). These results are not included in this report. The analytical data presented here can be used for baseline geochemical, mineral resource, and environmental geochemical studies.

Sixth circuit's unsettling interpretations of the Corps of Engineers' wetlands definition. United States v. Riverside Bayview Homes, Inc. , 729 F. 2d 391 (bth Cir. 1984), cert. granted, 53 U. S. L. W. 3597 (U. S. Feb. 19, 1985) (No. 84-701)  

SciTech Connect

The Sixth Circuit Court ruling in United States v. Riverside Bayview Homes, Inc. raises questions about the future of the Corps of Engineers' wetlands definition and regulatory permitting process. It contradicts the accepted congressional intent of the Clean Water Act and wetlands case law. It could also erode the Corps' regulatory authority over wetlands at a time when development encroaches on wetlands at a rate of 300,000 acres a year. The Supreme Court agreed to review the decision. If it reverses and remands it for an agency determination, this would assure uniformity among the circuit courts and assure the continued protection of wetlands.

Herpes simplex virus type 1 recombination: the Uc-DR1 region is required for high-level a-sequence-mediated recombination.  

PubMed Central

The a sequences of herpes simplex virus type 1 are believed to be the cis sites for inversion events that generate four isomeric forms of the viral genome. Using an assay that measures deletion of a beta-galactosidase gene positioned between two directly repeated sequences in plasmids transiently maintained in Vero cells, we had found that the a sequence is more recombinogenic than another sequence of similar size. To investigate the basis for the enhanced recombination mediated by the a sequence, we examined plasmids containing direct repeats of approximately 350 bp from a variety of sources and with a wide range of G+C content. We observed that all of these plasmids show similar recombination frequencies (3 to 4%) in herpes simplex virus type 1-infected cells. However, recombination between directly repeated a sequences occurs at twice this frequency (6 to 10%). In addition, we find that insertion of a cleavage site for an a-sequence-specific endonuclease into the repeated sequences does not appreciably increase the frequency of recombination, indicating that the presence of endonuclease cleavage sites within the a sequence does not account for its recombinogenicity. Finally, by replacing segments of the a sequence with DNA fragments of similar length, we have determined that only the 95-bp Uc-DR1 segment is indispensable for high-level a-sequence-mediated recombination.

THE NASA-UC ETA-EARTH PROGRAM. II. A PLANET ORBITING HD 156668 WITH A MINIMUM MASS OF FOUR EARTH MASSES  

SciTech Connect

We report the discovery of HD 156668 b, an extrasolar planet with a minimum mass of M{sub P} sin i = 4.15 M{sub +}. This planet was discovered through Keplerian modeling of precise radial velocities from Keck-HIRES and is the second super-Earth to emerge from the NASA-UC Eta-Earth Survey. The best-fit orbit is consistent with circular and has a period of P = 4.6455 days. The Doppler semi-amplitude of this planet, K = 1.89 m s{sup -1}, is among the lowest ever detected, on par with the detection of GJ 581 e using HARPS. A longer period (P {approx} 2.3 years), low-amplitude signal of unknown origin was also detected in the radial velocities and was filtered out of the data while fitting the short-period planet. Additional data are required to determine if the long-period signal is due to a second planet, stellar activity, or another source. Photometric observations using the Automated Photometric Telescopes at Fairborn Observatory show that HD 156668 (an old, quiet K3 dwarf) is photometrically constant over the radial velocity period to 0.1 mmag, supporting the existence of the planet. No transits were detected down to a photometric limit of {approx}3 mmag, ruling out transiting planets dominated by extremely bloated atmospheres, but not precluding a transiting solid/liquid planet with a modest atmosphere.

The American Indian Summer Institute in Earth System Science (AISESS) at UC Irvine: A Two-Week Residential Summer Program for High School Students  

NASA Astrophysics Data System (ADS)

Native Americans remain severely underrepresented in the geosciences, despite a clear need for qualified geoscience professionals within Tribal communities to address critical issues such as natural resource and land management, water and air pollution, and climate change. In addition to the need for geoscience professionals within Tribal communities, increased participation of Native Americans in the geosciences would enhance the overall diversity of perspectives represented within the Earth science community and lead to improved Earth science literacy within Native communities. To address this need, the Department of Earth System Science and the American Indian Resource Program at the University California have organized a two-week residential American Indian Summer Institute in Earth System Science (AISESS) for high-school students (grades 9-12) from throughout the nation. The format of the AISESS program is based on the highly-successful framework of a previous NSF Funded American Indian Summer Institute in Computer Science (AISICS) at UC Irvine and involves key senior personnel from the AISICS program. The AISESS program, however, incorporates a week of camping on the La Jolla Band of Luiseño Indians reservation in Northern San Diego County, California. Following the week of camping and field projects, the students spend a week on the campus of UC Irvine participating in Earth System Science lectures, laboratory activities, and tours. The science curriculum is closely woven together with cultural activities, native studies, and communication skills programs The program culminates with a closing ceremony during which students present poster projects on environmental issues relevant to their tribal communities. The inaugural AISESS program took place from July 15th-28th, 2012. We received over 100 applications from Native American high school students from across the nation. We accepted 40 students for the first year, of which 34 attended the program. The objective of the program is to introduce students to Earth System Science and, hopefully, inspire them to pursue Earth or Environmental Science degrees. Towards this end, we developed a fairly broad curriculum which will be presented here. Evaluation planning was conducted during the first quarter of 2012 during recruitment. A longitudinal database was established for the project to track college preparatory course-taking, GPA, school attendance, participation in earth science activities, and attitudes and interest in attending college and completing a degree after high school. Based on attendance during AISESS, schools and students will be selected as descriptive case studies. A pre-post design for evaluating the Summer Institute includes a survey about student background, attitudes, and knowledge about preparing to complete high school and attend college after graduation and focus groups of participants immediately after the Institute to capture qualitative data about their experiences in the field and at the University. Initial evaluation results will be presented here.

Yields of damage to C4' deoxyribose and to pyrimidines in pUC18 by the direct effect of ionizing radiation.  

PubMed

Our mechanistic understanding of damage formation in DNA by the direct effect relies heavily on what is known of free radical intermediates studied by EPR spectroscopy. Bridging this information to stable product formation requires methods with comparable sensitivities, a criterion met by the (32)P-post-labeling assay developed by Weinfeld and Soderlind, [Weinfeld,M. and Soderlind,K.-J.M. (1991) (32)P-Postlabeling detection of radiation-induced DNA damage: identification and estimation of thymine glycols and phosphoglycolate termini. Biochemistry, 30, 1091-1097] which when applied to the indirect effect, detected phosphoglycolate (pg) and thymine glycol (Tg). Here we applied this assay to the direct effect, measuring product yields in pUC18 films with hydration levels (?) of 2.5, 16 or 23 waters per nucleotide and X-irradiated at either 4 K or room temperature (RT). The yields of pg [G(pg)] for ? ? 2.5 were 2.8 ± 0.2 nmol/J (RT) and 0.2 ± 0.3 nmol/J (4 K), which is evidence that the C4' radical contributes little to the total deoxyribose damage via the direct effect. The yield of detectable base damage [G(B*)] at ? ? 2.5 was found to be 30.2 ± 1.0 nmol/J (RT) and 12.9 ± 0.7 nmol/J (4 K). While the base damage called B*, could be due to either oxidation or reduction, we argue that two reduction products, 5,6-dihydrouracil and 5,6-dihydrothymine, are the most likely candidates.

Functionality and Safety of an Ultra-Congruent Rotating Platform Knee Prosthesis at 5.6 Years: More than 5- Year Follow-Up of the e.motion® UC-TKA  

PubMed Central

Background: Mobile bearing TKA prostheses were designed to minimize polyethylene wear by increasing implant conformity and reducing stresses between the articulating prosthesis components. It is the purpose of this study to assess the mid-term functionality and clinical outcome associated with a highly congruent mobile platform design, the e.motion® UC total knee prosthesis. Material and Methods: Functional and clinical outcomes were assessed after an average of 5.6 years (5.1 – 6.0 years) after total knee arthroplasty in 28 patients (24 women), aged 77.8±7.5 years. The Knee injury and Osteoarthritis Outcome Score (KOOS) was assessed. Secondary outcomes included the Knee Society Score (KSS), radiological evaluation of radiolucent lines and recording of adverse events. Results: The average KOOS subscore for the activities of daily life was 77.8 points after 5.6 years. Both the clinical and functional KSS improved at 2.4 and 5.6 years. Two patients showed radiolucent lines at 5.6 years. Adverse events over 5.6 years included 3 subluxations, 1 tilting and 1 misalignment of the patella. None of the prostheses were revised. Conclusion: This pilot study shows promising outcomes for the e.motion® UC prosthesis. In the small sample, the implant performed comparably to the LCS prosthesis (the gold standard). There were no loosenings or revisions observed at 5.6 years.

Biographical information is provided for Daniel Chambers Macreight. He worked in Augustin-Pyramus de Candolle's herbarium at Geneva during the early 1830s, and later in the decade was prominent in medico-botanical circles in London. Macreight retired in 1840, due to ill-health, and moved to Jersey in the Channel Islands where he died. In 1837, he published an innovative "Manual of the British flora" which covered both native and cultivated plants. This flora contained two novel features: dichotomous keys were provided to assist students to identify plants, and the category subspecies was employed for taxa within the genera "Rosa," "Rubus" and "Salix."

Science Education at Riverside Middle School A Case Study  

NASA Astrophysics Data System (ADS)

For more than thirty years the gender gap in science and related careers has been a key concern of researchers, teachers, professional organizations, and policy makers. Despite indicators of progress for women and girls on some measures of achievement, course enrollment patterns, and employment, fewer women than men pursue college degrees and careers in science, technology, engineering, and mathematics. According to the results of national assessments, the gender gap in science achievement begins to be evident in the middle school years. Gender and school science achievement involve a complex set of factors associated with schools and child/family systems that may include school leadership, institutional practices, curriculum content, teacher training programs, teacher expectations, student interests, parental involvement, and cultural values. This ethnographic case study was designed to explore the context for science education reform and the participation of middle school girls. The study analyzed and compared teaching strategies and female student engagement in sixth, seventh, and eighth grade science classrooms. The setting was a middle school situated in a district that was well-known for its achievement in reading, math, and technology. Findings from the study indicated that while classroom instruction was predominantly organized around traditional school science, the girls were more disciplined and outperformed the boys. The size of the classrooms, time to prepare for hands-on activities, and obtaining resources were identified as barriers to teaching science in ways that aligned with recent national science reform initiatives. Parents who participated in the study were very supportive of their daughters' academic progress and career goals. A few of the parents suggested that the school's science program include more hands-on activities; instruction designed for the advanced learner; and information related to future careers. Overall the teachers and students perceived their science program to be gender fair. Eighth grade participants who had career goals related to science and engineering, indicated that their science instruction did not provide the rigor they needed to improve their critical skills for advanced placement in high school. Recommendations include the need for professional development on inquiry-based science, equitable student achievement, and diverse perspectives in science education.

UC Berkeley Seismic Guidelines, Appendix II: Ground Motion TimeHistories for the UC Berkeley Campus  

SciTech Connect

Three sets of ten time histories each were developed to represent the ground motions for each of the three return periods. All of the time histories are provided as pairs of fault-normal and fault-parallel components. The ground motion time histories are provided in two forms: unmodified, and spectrally modified to match the probabilistic response spectra. The unmodified time histories can be scaled to match the probabilistic response spectra at a specified period, such as the first mode period of the structure being analyzed, while leaving the shape of the response spectrum unmodified. This approach preserves the particular characteristics of the individual time history, together with the peaks and troughs of its response spectrum. These individual characteristics are modified in the spectrally matched time histories, resulting in a suite of ten time histories (for a given return period) that all have the same response spectrum for a given component (fault normal or fault parallel) that follows the smooth shape of the probabilistic response spectrum.

This proposal is for the continuation of the High Energy Physics program at the University of California at Riverside. In hadron collider physics the authors will complete their transition from experiment UA1 at CERN to the DZERO experiment at Fermilab. On experiment UA1 their effort will concentrate on data analysis at Riverside. At Fermilab they will coordinate the high voltage system for all detector elements. They will also carry out hardware/software development for the D0 muon detector. The TPC/Two-Gamma experiment has completed its present phase of data-taking after accumulating 160 pb{sup {minus}}1 of luminosity. The UC Riverside group will continue data and physics analysis and make minor hardware improvement for the high luminosity run. The UC Riverside group is participating in design and implementation of the data acquisition system for the OPAL experiment at LEP. Mechanical and electronics construction of the OPAL hadron calorimeter strip readout system is proceeding on schedule. Data analysis and Monte Carlo detector simulation efforts are proceeding in preparation for the first physics run when IEP operation comenses in fall 1989.

Status of the UC-Berkeley SETI efforts  

NASA Astrophysics Data System (ADS)

We summarize radio and optical SETI programs based at the University of California, Berkeley. The SEVENDIP optical pulse search looks for ns time scale pulses at visible wavelengths. It utilizes an automated 30 inch telescope, three ultra fast photo multiplier tubes and a coincidence detector. The target list includes F, G, K and M stars, globular cluster and galaxies. The ongoing SERENDIP V.v sky survey searches for radio signals at the 300 meter Arecibo Observatory. The currently installed configuration supports 128 million channels over a 200 MHz bandwidth with ~1.6 Hz spectral resolution. Frequency stepping allows the spectrometer to cover the full 300MHz band of the Arecibo L-band receivers. The final configuration will allow data from all 14 receivers in the Arecibo L-band Focal Array to be monitored simultaneously with over 1.8 billion channels. SETI@home uses the desktop computers of volunteers to analyze over 160 TB of data at taken at Arecibo. Over 6 million volunteers have run SETI@home during its 10 year history. The SETI@home sky survey is 10 times more sensitive than SERENDIP V.v but it covers only a 2.5 MHz band, centered on 1420 MHz. SETI@home searches a much wider parameter space, including 14 octaves of signal bandwidth and 15 octaves of pulse period with Doppler drift corrections from -100 Hz/s to +100 Hz/s. SETI@home is being expanded to analyze data collected during observations of Kepler objects of interest in May 2011. The Astropulse project is the first SETI search for ?s time scale pulses in the radio spectrum. Because short pulses are dispersed by the interstellar medium, and the amount of dispersion is unknown, Astropulse must search through 30,000 possible dispersions. Substantial computing power is required to conduct this search, so the project uses volunteers and their personal computers to carry out the computation (using distributed computing similar to SETI@home). Keywords: radio instrumentation, FPGA spectrometers, SETI, optical SETI, Search for Extraterrestrial Intelligence, volunteer computing, radio transients, optical transients.

During the past year, record performance has been obtained at W-Band from the University of California, Davis TE01 proof-of-principle gyro-TWT: 75 kW output, 45 dB gain, 22.5 % efficiency, and 3.7 % saturated bandwidth (BW) at 93.5 GHz. We report the design and fabrication of a new follow-on ultra high gain (71 dB) gyro-TWT (thereby permitting the direct use of a MMIC driver) producing 110 kW output at 5 % BW (with design rules consistent with 10% duty) with the focus on advanced millimeter wave radars. The existing gun and solenoid will be used, but the entire circuit and collector will be replaced by the new design. The work is proceeding in two stages. First, we will maintain the saturated gain at the current level (45 dB) and fabricate an interaction circuit intended for operation at full design parameters (e.g. 110 kW, 5% BW, stable) with the rf brought straight out of the tube in the TE01 mode. There will be an uptaper from the interaction waveguide to an output waveguide of larger radius, which will also serve as the collector. Following these initial experiments, we will proceed to the ultra high gain case where the gain level would permit use of a solid state driver.

Characterization of Vegetation using the UC Davis Remote Sensing Testbed  

NASA Astrophysics Data System (ADS)

Remote sensing provides information about the dynamics of the terrestrial biosphere with continuous spatial and temporal coverage on many different scales. We present the design and construction of a suite of instrument modules and network infrastructure with size, weight and power constraints suitable for small scale vehicles, anticipating vigorous growth in unmanned aerial vehicles (UAV) and other mobile platforms. Our approach provides the rapid deployment and low cost acquisition of high aerial imagery for applications requiring high spatial resolution and revisits. The testbed supports a wide range of applications, encourages remote sensing solutions in new disciplines and demonstrates the complete range of engineering knowledge required for the successful deployment of remote sensing instruments. The initial testbed is deployed on a Sig Kadet Senior remote controlled plane. It includes an onboard computer with wireless radio, GPS, inertia measurement unit, 3-axis electronic compass and digital cameras. The onboard camera is either a RGB digital camera or a modified digital camera with red and NIR channels. Cameras were calibrated using selective light sources, an integrating spheres and a spectrometer, allowing for the computation of vegetation indices such as the NDVI. Field tests to date have investigated technical challenges in wireless communication bandwidth limits, automated image geolocation, and user interfaces; as well as image applications such as environmental landscape mapping focusing on Sudden Oak Death and invasive species detection, studies on the impact of bird colonies on tree canopies, and precision agriculture.

Primary and secondary carbonaceous species in the atmosphere of Western Riverside County, California  

NASA Astrophysics Data System (ADS)

Elemental carbon (EC), organic carbon (OC) and PM 2.5 mass concentrations were measured from September 2001 through January 2002 in Mira Loma, CA. EC and OC were analyzed using the NIOSH (National Institute of Occupational Safety and Health) 5040 thermal/optical transmittance method. OC concentrations in Mira Loma were found to be higher than those of other urban sites in the South Coast Air Basin (SoCAB), while EC concentrations were comparable to or lower than those of other SoCAB sites. Overall, OC and EC concentrations accounted for 26% and 5% of the total PM 2.5, respectively. OC/EC ratios ranged from 1.6 to 12.8 with an average of 5.2. These values were higher than those observed at other urban sites in the United States by a factor of 2. A stronger correlation between suspended OC and EC concentrations was noted in months with lower photochemical activity (December and January, r=0.82) than in months with greater photochemical activity (September and October, r=0.64). The elevated levels of OC, OC/EC ratios, and the seasonal difference in correlation between OC and EC concentrations were attributed in part to significant secondary organic aerosol formation. The fraction of total organic carbon that was secondary organic carbon (SOC) was estimated using the OC/EC minimum ratio method and Chemical Mass Balance (CMB) modeling. Based on the OC/EC minimum ratio method, the contribution of SOC to the total organic carbon tended to be higher during the months with greater photochemical activity (63%) than those with lower photochemical activity (44%). Based on CMB modeling, SOC contributed to 14% of the total PM 2.5 mass and 57% of the total organic carbon during the study period. Overall, these findings suggest that photochemical activity can appreciably affect total PM 2.5 mass concentrations in Mira Loma, and that measures to control emissions of SOC precursors incorporated as part of a region-wide air quality management plan could lead to a perceptible drop in total PM 2.5 mass concentrations in this area.

Intensive early season adulticide applications decrease arbovirus transmission throughout the Coachella Valley, Riverside County, California.  

PubMed

In the Coachella Valley of California the seasonal onset of St. Louis encephalitis virus (SLEV), western equine encephalomyelitis virus (WEEV), and West Nile virus (WNV) has been detected consistently at the shoreline of the Salton Sea near the community of North Shore. The timing and intensity of initial amplification in the Culex tarsalis Coquillett/wild bird cycle at this focus seemed closely linked to the subsequent dispersal of virus to the rest of the Coachella Valley and perhaps southern California. In 2004, an attempt was made to interrupt the amplification and dispersal of WNV using ground ultra-low volume (ULV) applications of Pyrenone 25-5. Although these localized treatments were started 1 month after the initial detection in April, surveillance indicated no dispersal from this focus at this time. However, these treatments appeared to have little effect, and WNV eventually was detected throughout the valley, with seven human cases reported in the urbanized upper valley near Palm Springs. In 2005, the initial detection of WNV at North Shore at the end of May was followed rapidly by dispersal throughout the valley precluding efforts at containment. Evaluation of ground and aerial applications at North Shore during May and June 2005, respectively, indicated variable kill of sentinel mosquitoes (overall mortality: ground, 43%; air, 34%) and limited control of the target Cx. tarsalis population. In 2006, aerial ULV applications with the same chemical were begun immediately following the first detection of virus in mid-April, resulting in an apparent reduction of Cx. tarsalis abundance and delay of WNV activity in the rural lower valley and a marked decline in transmission by Culex quinquefasciatus Say populations in the densely populated upper northwestern valley with no human cases reported.

Geologic map of the Valley Mountain 15’ quadrangle, San Bernardino and Riverside Counties, California  

USGS Publications Warehouse

The Valley Mountain 15’ quadrangle straddles the Pinto Mountain Fault, which bounds the eastern Transverse Ranges in the south against the Mojave Desert province in the north. The Pinto Mountains, part of the eastern Transverse Ranges in the south part of the quadrangle expose a series of Paleoproterozoic gneisses and granite and the Proterozoic quartzite of Pinto Mountain. Early Triassic quartz monzonite intruded the gneisses and was ductiley deformed prior to voluminous Jurassic intrusion of diorite, granodiorite, quartz monzonite, and granite plutons. The Jurassic rocks include part of the Bullion Mountains Intrusive Suite, which crops out prominently at Valley Mountain and in the Bullion Mountains, as well as in the Pinto Mountains. Jurassic plutons in the southwest part of the quadrangle are deeply denuded from midcrustal emplacement levels in contrast to supracrustal Jurassic limestone and volcanic rocks exposed in the northeast. Dikes inferred to be part of the Jurassic Independence Dike Swarm intrude the Jurassic plutons and Proterozoic rocks. Late Cretaceous intrusion of the Cadiz Valley Batholith in the northeast caused contact metamorphism of adjacent Jurassic plutonic rocks. The Tertiary period saw emplacement of basanitoid basalt at about 23 Ma and deposition of Miocene and (or) Pliocene ridge-capping gravels. An undated east-dipping low-angle normal fault zone in the Pinto Mountains drops hanging-wall rocks eastward and may account for part of the contrast in uplift history across the quadrangle. The eastern Transverse Ranges are commonly interpreted as severely rotated clockwise tectonically in the Neogene relative to the Mojave Desert, but similar orientations of Jurassic dike swarms suggest that any differential rotation between the two provinces is small in this quadrangle. The late Cenozoic Pinto Mountain Fault and other strike-slip faults cut Quaternary deposits in the quadrangle, with two northwest-striking faults cutting Holocene deposits. Geographic Information System and metadata on most geologic features are available on the Geologic map of the Sheep Hole Mountains 30’ by 60’ quadrangle, U.S. Geological Survey map MF–2234, scale 1:100,000, available at http://pubs.usgs.gov/mf/2002/2344/.

Semi-continuous mass closure of the major components of fine particulate matter in Riverside, CA  

NASA Astrophysics Data System (ADS)

The application of newly developed semi-continuous aerosol monitors allows for the measurement of all the major species of PM 2.5 on a 1-h time basis. Temporal resolution of both non-volatile and semi-volatile species is possible. A suite of instruments to measure the major chemical species of PM 2.5 allows for semi-continuous mass closure. A newly developed dual-oven Sunset carbon monitor is used to measure non-volatile organic carbon, semi-volatile organic carbon and elemental carbon. Inorganic species, including sulfate and nitrate, can be measured with an ion chromatograph based sampler. Comparison of the sum of the major chemical species in an urban aerosol with mass measured by an FDMS resulted in excellent agreement. Linear regression analysis resulted in a zero-intercept slope of 0.98±0.01 with an R2=0.86. One-hour temporal resolution of the major species of PM 2.5 may reduce the uncertainty in receptor based source apportionment modeling, will allow for better forecasting of PM 2.5 episodes, and may lead to increased understanding of related health effects.

Using NASA climate data to improve effectiveness of undergraduate-level climate change education  

NASA Astrophysics Data System (ADS)

Global climate change is one of the greatest challenges facing society today, and yet the science of global climate change and the potential effects are poorly understood by the general population. Through a NASA Innovations in Climate Education grant, UC Riverside is addressing this disconnect by fully redesigning the undergraduate level Earth Sciences courses, which serve over 3,000 students every year. The majority of these students are not Earth Sciences majors and so these changes in the climate change education curriculum reach a very broad range of students. This new curriculum centers around a new website that hosts online activities that allows students to utilized and manipulate NASA climate data sets in order to directly observe changes in the global climate system. All lower division Earth Sciences courses will include online activities and a unit on global climate change. In addition to this general improvement in climate change education, we have restructured our lower division Climate Change course (GEO 11) to focus on these online activities in order to give students first-hand experience with both global and local climate data. Because these activities are hosted online, they can be seemlessly integrated with other online resources, accessed from school or home and be viewed on a variety of devices, thus vastly increasing student accessibility. In the future, these activities will be available to other institutions. UC Riverside is an ideal institution at which to launch a broad-reaching climate change education program like this. As one of the most socioeconomically and ethnically diverse universities and one of only two federally-designated Hispanic Serving Research Institutions, UC Riverside primarily educates undergraduate students from the portions of society that will be most heavily impacted by the effects of climate change. GEO 11 and the other lower division courses produce climate-literate students of different majors and backgrounds, who can continue on to serve as climate science advocates in society.

The geologic map and digital database of the San Bernardino Wash quadrangle are products of a regional geologic mapping effort undertaken in the eastern Transverse Ranges in and around Joshua Tree National Park. This investigation, part of the Southern California Areal Mapping Project (SCAMP), is conducted in cooperation with the California Geologic Survey and the National Park Service. In line with the goals of the National Cooperative Geologic Mapping Program (NCGMP), mapping of the San Bernardino Wash and other quadrangles has been directed toward generating a multipurpose digital geologic map database that is applicable to land-related investigations in the earth and biological sciences. This mapping is conducted to further understanding of bedrock geology and surficial processes in the region and to document evidence for seismotectonic activity in the eastern Transverse Ranges. It is also intended to serve as a base layer suitable for ecosystem and mineral resource assessment and for building a hydrogeologic framework for Pinto Basin. Initial investigations span Pinto Basin from the Hexie and Eagle Mountains northward into the Pinto Mountains (see fig. 1). Quadrangles mapped include the Conejo Well 7.5-minute quadrangle (Powell, 2001a), the Porcupine Wash 7.5-minute quadrangle (Powell, 2001b), the Pinto Mountain 7.5-minute quadrangle (Powell, 2002), and the San Bernardino Wash 7.5-minute quadrangle. Parts of the San Bernardino Wash quadrangle had been mapped previously at a variety of scales (Weir, and Bader, 1963; Hope, 1966, 1969; Jennings, 1967; Powell, 1981, 1993).

Salton Seismic Imaging Project Line 6: San Andreas Fault and Northern Coachella Valley Structure, Riverside and San Bernardino Counties, California  

NASA Astrophysics Data System (ADS)

The Salton Seismic Imaging Project (SSIP) is a large-scale, active- and passive-source seismic project designed to image the San Andreas fault (SAF) and adjacent basins (Imperial and Coachella Valleys) in southernmost California. Data and preliminary results from many of the seismic profiles are reported elsewhere (including Fuis et al., Rymer et al., Goldman et al., Langenheim et al., this meeting). Here, we focus on SSIP Line 6, one of four 2-D seismic profiles that were acquired across the Coachella Valley. The 44-km-long, SSIP-Line-6 seismic profile extended from the east flank of Mt. San Jacinto northwest of Palm Springs to the Little San Bernardino Mountains and crossed the SAF (Mission Creek (MCF), Banning (BF), and Garnet Hill (GHF) strands) roughly normal to strike. Data were generated by 10 downhole explosive sources (most spaced about 3 to 5 km apart) and were recorded by approximately 347 Texan seismographs (average spacing 126 m). We used first-arrival refractions to develop a P-wave refraction tomography velocity image of the upper crust along the seismic profile. The seismic data were also stacked and migrated to develop low-fold reflection images of the crust. From the surface to about 7 km depth, P-wave velocities range from about 2.5 km/s to about 7.2 km/s, with the lowest velocities within an ~2-km-deep, ~20-km-wide basin, and the highest velocities below the transition zone from the Coachella Valley to Mt. San Jacinto and within the Little San Bernardino Mountains. The BF and GHF strands bound a shallow sub-basin on the southwestern side of the Coachella Valley, but the underlying shallow-depth (~4 km) basement rocks are P-wave high in velocity (~7.2 km/s). The lack of a low-velocity zone beneath BF and GHF suggests that both faults dip northeastward. In a similar manner, high-velocity basement rocks beneath the Little San Bernardino Mountains suggest that the MCF dips vertically or southwestward. However, there is a pronounced low-velocity zone in basement rocks between about 2 and 7 km depth beneath and southwest of the MCF, suggesting a vertical or slightly southwest-dipping MCF. The apparent northeast dip of the BF and the apparent vertical or southwest dip of the MCF suggests that the two main strands of the SAF (MCF and BF) merge at about 10 km depth. A plot of double-difference earthquake hypocenters (Hauksson, 2000) along the seismic profile shows events that occurred between 1980-2000 (excluding those in 1992, prior to and after the Joshua Tree and Landers earthquakes) are largely confined to the vicinity of the basement low-velocity zone between the MCF and BF. However, a separate alignment of hypocenters occurs southwest of the BF and projects toward the surface beneath Mt. San Jacinto. Collectively, the velocity images and the seismicity data suggest the BF strand of the SAF dips to the northeast at about 50 degrees in the upper 10 km, and the MCF strand is either vertical or dips southwestward about 80 degrees, with both strands merging at about 10 km depth and forming a near-vertical zone of faults to at least 15 km depth. The SSIP Line 6 data are consistent with structures interpreted by Catchings et al. (2009).

Salton Seismic Imaging Project Line 5—the San Andreas Fault and Northern Coachella Valley Structure, Riverside County, California  

NASA Astrophysics Data System (ADS)

The Salton Seismic Imaging Project (SSIP) is a large-scale, active- and passive-source seismic project designed to image the San Andreas Fault (SAF) and the adjacent basins (Imperial and Coachella Valleys) in southern California. Here, we focus on SSIP Line 5, one of four 2-D NE-SW-oriented seismic profiles that were acquired across the Coachella Valley. The 38-km-long SSIP-Line-5 seismic profile extends from the Santa Rosa Ranges to the Little San Bernardino Mountains and crosses both strands of the SAF, the Mission Creek (MCF) and Banning (BF) strands, near Palm Desert. Data for Line 5 were generated from nine buried explosive sources (most spaced about 2 to 8 km apart) and were recorded on approximately 281 Texan seismographs (average spacing 138 m). First-arrival refractions were used to develop a refraction tomographic velocity image of the upper crust along the seismic profile. The seismic data were also stacked and migrated to develop low-fold reflection images of the crust. From the surface to about 8 km depth, P-wave velocities range from about 2 km/s to more than 7.5 km/s, with the lowest velocities within a well-defined (~2-km-deep, 15-km-wide) basin (< 4 km/s), and the highest velocities below the transition from the Coachella Valley to the Santa Rosa Ranges on the southwest and within the Little San Bernardino Mountains on the northeast. The MCF and BF strands of the SAF bound an approximately 2.5-km-wide horst-type structure on the northeastern side of the Coachella Valley, beneath which the upper crust is characterized by a pronounced low-velocity zone that extends to the bottom of the velocity image. Rocks within the low-velocity zone have significantly lower velocities than those to the northeast and the southwest at the same depths. Conversely, the velocities of rocks on both sides of the Coachella Valley are greater than 7 km/s at depths exceeding about 4 km. The relatively narrow zone of shallow high-velocity rocks between the surface traces of the MCF and BF strands is associated with a zone of uplifted strata. Along SSIP Line 5, we infer that the MCF and BF strands are steeply dipping and merge at about 2 km depth. We base our interpretation on a prominent basement low-velocity zone (fault zone) that is centered southwest of the MCF and BF strands and extends to at least 8 km depth.

Geologic map and digital database of the Yucaipa 7.5' quadrangle, San Bernardino and Riverside Counties, California  

USGS Publications Warehouse

This geologic database of the Yucaipa 7.5' quadrangle was prepared by the Southern California Areal Mapping Project (SCAMP), a regional geologic-mapping project sponsored jointly by the U.S. Geological Survey and the California Geological Survey. The database was developed as a contribution to the National Cooperative Geologic Mapping Program's National Geologic Map Database, and is intended to provide a general geologic setting of the Yucaipa quadrangle. The database and map provide information about earth materials and geologic structures, including faults and folds that have developed in the quadrangle due to complexities in the San Andreas Fault system. The Yucaipa 7.5' quadrangle contains materials and structures that provide unique insight into the Mesozoic and Cenozoic geologic evolution of southern California. Stratigraphic and structural elements include: (1) strands of the San Andreas Fault that bound far-traveled terranes of crystalline and sedimentary rock; (2) Mesozoic crystalline rocks that form lower and upper plates of the regionwide Vincent-Orocopia Thrust system; and (3) late Tertiary and Quaternary sedimentary materials and geologic structures that formed during the last million years or so and that record complex geologic interactions within the San Andreas Fault system. These materials and the structures that deform them provide the geologic framework for investigations of geologic hazards and ground-water recharge and subsurface flow. Geologic information contained in the Yucaipa database is general-purpose data that is applicable to land-related investigations in the earth and biological sciences. The term "generalpurpose" means that all geologic-feature classes have minimal information content adequate to characterize their general geologic characteristics and to interpret their general geologic history. However, no single feature class has enough information to definitively characterize its properties and origin. For this reason the database cannot be used for site-specific geologic evaluations, although it can be used to plan and guide investigations at the site-specific level.

This source is particularly well suited to detailed study because it is nearby (distance ~ 3 kpc), very luminous (L ~ 3*E(5) L_?), and morphologically simple (shell type, isolated). Nine transitions in five molecular species (HCO(+) , H(13) CN, SO, CH3CN, (12) CO) and the H41alpha recombination line were mapped using the Hat Creek and Nobeyama arrays with 2(''}-8({'')) angular resolution and ~ 1 km/s velocity resolution. These observations show that the HII region is rapidly expanding into the surrounding warm (T>50 K), massive (M ~ 1000 M_?) molecular core and confirm that the associated bipolar outflow is the most energetic yet discovered. The HCO(+) J=1-0 spectrum towards the HII region shows an inverse P-Cygni profile that is most simply interpreted as evidence for remnant infall. We have modelled the detailed velocity and density structure of the cloud using a spherically symmetric, multi-level, non-LTE radiative transfer code and find that the observed HCO(+) J=1-0 and J=3-2 spectra and spatial distributions are successfully reproduced by an overall collapse of the molecular core.

UC Berkeley Nuclear Engineering Curriculum and Research Enhancement. Final report, February 14, 1993--February 14, 1995  

SciTech Connect

This is a report for the 2/14/93 to 2/14/95 period of the five-year program proposed and initiated in 1992, for curriculum and research enhancement for the Department of Nuclear Engineering at the University of California, Berkeley. The program is designed to strengthen the departmental academic infrastructure and improve the education breadth of nuclear engineering students. The DOE funds have supported scholarships and a novel educational program which includes summer coursework at the Diablo Canyon Nuclear Power Plant. The summer course provides an important introduction to reactor safety and operations to students who will in the future be responsible for running many of our existing nuclear power plants. The work was funded under DOE contract DE-FG0393ER75856, with a matching gift to the Department from the Pacific Gas and Electric Company (PG&E). The program described in the original grant proposal has been successful implemented with an enthusiastic response from our students and faculty. The program consisted of two parts, one for innovative additions to our curriculum funded by the DOE, and the other for distinguished lectureships and support for basic research funded by gifts from PG&E.

Monitoring Based Commissioning: Benchmarking Analysis of 24 UC/CSU/IOU Projects  

SciTech Connect

Buildings rarely perform as intended, resulting in energy use that is higher than anticipated. Building commissioning has emerged as a strategy for remedying this problem in non-residential buildings. Complementing traditional hardware-based energy savings strategies, commissioning is a 'soft' process of verifying performance and design intent and correcting deficiencies. Through an evaluation of a series of field projects, this report explores the efficacy of an emerging refinement of this practice, known as monitoring-based commissioning (MBCx). MBCx can also be thought of as monitoring-enhanced building operation that incorporates three components: (1) Permanent energy information systems (EIS) and diagnostic tools at the whole-building and sub-system level; (2) Retro-commissioning based on the information from these tools and savings accounting emphasizing measurement as opposed to estimation or assumptions; and (3) On-going commissioning to ensure efficient building operations and measurement-based savings accounting. MBCx is thus a measurement-based paradigm which affords improved risk-management by identifying problems and opportunities that are missed with periodic commissioning. The analysis presented in this report is based on in-depth benchmarking of a portfolio of MBCx energy savings for 24 buildings located throughout the University of California and California State University systems. In the course of the analysis, we developed a quality-control/quality-assurance process for gathering and evaluating raw data from project sites and then selected a number of metrics to use for project benchmarking and evaluation, including appropriate normalizations for weather and climate, accounting for variations in central plant performance, and consideration of differences in building types. We performed a cost-benefit analysis of the resulting dataset, and provided comparisons to projects from a larger commissioning 'Meta-analysis' database. A total of 1120 deficiency-intervention combinations were identified in the course of commissioning the projects described in this report. The most common location of deficiencies was in HVAC equipment (65% of sites), followed by air-handling and distributions systems (59%), cooling plant (29%), heating plants (24%), and terminal units (24%). The most common interventions were adjusting setpoints, modifying sequences of operations, calibration, and various mechanical fixes (each done in about two-thirds of the sites). The normalized rate of occurrence of deficiencies and corresponding interventions ranged from about 0.1/100ksf to 10/100ksf, depending on the issue. From these interventions flowed significant and highly cost-effective energy savings For the MBCx cohort, source energy savings of 22 kBTU/sf-year (10%) were achieved, with a range of 2% to 25%. Median electricity savings were 1.9 kWh/sf-year (9%), with a range of 1% to 17%. Peak electrical demand savings were 0.2 W/sf-year (4%), with a range of 3% to 11%. The aggregate commissioning cost for the 24 projects was $2.9 million. We observed a range of normalized costs from $0.37 to 1.62/sf, with a median value of $1.00/sf for buildings that implemented MBCx projects. Per the program design, monitoring costs as a percentage of total costs are significantly higher in MBCx projects (median value 40%) than typical commissioning projects included in the Meta-analysis (median value of 2% in the commissioning database). Half of the projects were in buildings containing complex and energy-intensive laboratory space, with higher associated costs. Median energy cost savings were $0.25/sf-year, for a median simple payback time of 2.5 years. Significant and cost-effective energy savings were thus obtained. The greatest absolute energy savings and shortest payback times were achieved in laboratory-type facilities. While impacts varied from project to project, on a portfolio basis we find MBCx to be a highly cost-effective means of obtaining significant program-level energy savings across a variety of building types. Energy savings are ex

Development of a coded-aperture backscatter imager using the UC San Diego HEXIS detector  

NASA Astrophysics Data System (ADS)

Defence R&D Canada-Suffield and the University of California, San Diego, have recently begun a collaborative effort to develop a coded aperture based X-ray backscatter imaging detector that will provide sufficient speed, contrast and spatial resolution to detect antipersonnel landmines and improvised explosive devices. While our final objective is to field a hand-held detector, we have currently constrained ourselves to a design that can be fielded on a small robotic platform. Coded aperture imaging has been used by the observational X-ray and gamma ray astronomy community for a number of years, which has driven advances in detector design that is now being realized in systems that are substantially faster, cheaper and lighter than those only a decade ago. With these advances, a coded aperture hand-held imaging system has only recently become a possibility. One group at the Center for Astrophysics and Space Sciences, University of California, San Diego, has had a longterm programme developing the CZT based HEXIS detector as the detection element of a coded aperture imager. Designed as a satellite payload, this low-power system is ruggedized and light-weight, all necessary qualities for incorporation into the envisioned portable imaging system. This paper will begin with an introduction to the landmine and improvised explosive device detection problem, followed by a discussion of the HEXIS detector. We will then present early results from our proof-of-principle experiments, and conclude with a discussion on future work.

The U.C. Berkeley infrared spatial interferometer - Instrumentation and first results  

NASA Astrophysics Data System (ADS)

An infrared spatial interferometer (ISI) designed for high-resolution imaging, using earth-rotation aperture synthesis techniques is described. ISI employs two Pfund-type telescopes allowing all optics and electronics to be contained in one standard-size semitrailer per telescope. The interferometer is designed for a maximum baseline of 1000 m which would give an angular resolution of nearly 0.001 arc sec. The use of HeNe laser metrology systems and a microcomputer workstation is addressed, along with heterodyne detection and IF signal processing and correlation. Interferometry results obtained on IRC + 10216 with the initial 4-m east-west baseline are presented, and it is noted that the sensitivity of the present system is such that a one-hour integration time should be adequate to detect fringes on sources six mag fainter than the brightest IR sources.

Experimental Status of the UC Davis Advanced X-Band Photoinjector Facility*  

NASA Astrophysics Data System (ADS)

A novel source of transform-limited pulses of coherent electromagnetic radiation relying on the synchrotron radiation process in a fast wave guiding structure is investigated. An ultrashort electron bunch transversally accelerated by a periodic external field is considered. At grazing, where the bunch and group velocities are matched, the duration of the resulting ultrawideband chirped pulse is governed by group velocity dispersion instead of slippage. Because of the intimate connection between the rate of chirping and the bandwidth, the corresponding pulse duration is shown to be very close to the Fourier transform limit. In addition, the propagation of such chirped pulses through a guiding structure with negative group velocity dispersion is investigated. The spectral and temporal characteristics of the chirped and compressed pulses are derived analytically. Detailed computer calculations complement this theoretical analysis. *Work supported in part by DoD/AFOSR (MURI) F49620-95-1-0253, AFOSR (ATRI) F30602-94-2-001, ARO DAAHO4-95-1-0336 and LLNL/LDRD DoE W-7405-ENG-48

High angular resolution 7 mm images toward the UC HII region W3(OH)  

NASA Astrophysics Data System (ADS)

Context. Recent high angular resolution radio observations of the ultracompact H ii region W3(OH) confirm the presence of an extremely compact (0.''05), time-variable source near its center. Aims: We use new, sensitive high angular resolution observations of radio continuum and recombination lines to study the compact source in W3(OH) and the ultracompact H ii region itself. Methods: We reduced and analyzed extensive Jansky Very Large Array observations of W3(OH) in the continuum at 41.0 GHz and in the H54? and He54? lines. Results: Our images confirm there is the compact source and show that it is connected by a linear filament to the brightest part of W3(OH). We discuss several possible explanations for this structure and propose future observations that may clarify its nature.

In commercial nuclear activities, spent fuel back end management is a key issue for nuclear countries as spent fuel represent most of national civil nuclear waste legacy. Ensuring public safety and protection of the environment, now and in the future has been and still remains a major commitment, it is still the subject of thorough development efforts and active public debates. Considerable benefits can be obtained from the Universal Canister strategy as implemented in France in spent fuel treatment and waste conditioning based on reprocessing. COGEMA developed sophisticated waste conditioning processes to simplify High Level and Long Lived Intermediate Level Waste storage and final disposal. Main benefits are: waste stabilization by immobilization and encapsulation; ultimate waste toxicity reduction; drastic ultimate waste volume reduction; and ultimate waste packages standardization.

UC/MALDI-MS analysis of HDL; evidence for density-dependent post-translational modifications  

NASA Astrophysics Data System (ADS)

The purpose of this study is to determine whether the nature of the post-translational modifications of the major apolipoproteins of HDL is different for density-distinct subclasses. These subclasses were separated by ultracentrifugation using a novel density-forming solute to yield a high-resolution separation. The serum of two subjects, a control with a normolipidemic profile and a subject with diagnosed cardiovascular disease, was studied. Aliquots of three HDL subclasses were analyzed by MALDI and considerable differences were seen when comparing density-distinct subclasses and also when comparing the two subjects. A detailed analysis of the post-translational modification pattern of apoA-1 shows evidence of considerable protease activity, particularly in the more dense fractions. We conclude that part of the heterogeneity of the population of HDL particles is due to density-dependent protease activity.

Training the translational research teams of the future: UC Davis-HHMI Integrating Medicine into Basic Science program.  

PubMed

There is a need for successful models of how to recruit, train, and retain bench scientists at the earliest stages of their careers into translational research. One recent, promising model is the University of California Davis Howard Hughes Medical Institute Integrating Medicine into Basic Science (HHMI-IMBS) program, part of the HHMI Med into Grad initiative. This paper outlines the HHMI-IMBS program's logic, design, and curriculum that guide the goal of research that moves from bedside to bench. That is, a curriculum that provides graduate students with guided translational training, clinical exposure, team science competencies, and mentors from diverse disciplines that will advance the students careers in clinical translational research and re-focusing of research to answer clinical dilemmas. The authors have collected data on 55 HHMI-IMBS students to date. Many of these students are still completing their graduate work. In the current study the authors compare the initial two cohorts (15 students) with a group of 29 control students to examine the program success and outcomes. The data indicate that this training program provides an effective, adaptable model for training future translational researchers. HHMI-IMBS students showed improved confidence in conducting translational research, greater interest in a future translational career, and higher levels of research productivity and collaborations than a comparable group of predoctoral students.

Possible role of laccase from Fusarium incarnatum UC-14 in bioremediation of Bisphenol A using reverse micelles system.  

PubMed

Bisphenol A [2,2 bis (4 hydroxyphenyl) propane] is widely used in the variety of industrial and residential applications such as the synthesis of polymers including polycarbonates, epoxy resins, phenol resins, polyesters and polyacrylates. BPA has been recognized as an Endocrine Disrupting Chemicals (EDC), thus it is necessary to assess its biodegradability or fate in the natural environment. In general, environmental pollutant such as BPA does not dissolve in aqueous media, owing to their high hydrophobicity, and hence non-aqueous catalysis can be employed to enhance biodegradability of phenolic environmental pollutant. Purified laccase hosted in reverse micelles using ternary system of isooctane: AOT [Bis (2-ethylhexyl) sulphosuccinate sodium salt)]:water having hydration ratio (Wo) of 30 with protein concentration of 43.5 ?g/ml was found to eliminate 91.43% of 200 ppm of Bisphenol A at 50 °C, pH-6.0 when incubated with laccase/Reverse Micelles system for 75 min. GC-MS analysis of isooctane soluble fractions detected the presence of 4,4'-(2 hydroxy propane 1,2 diyl) diphenol, bis (4-hydroxylphenyl) butenal and 2-(1-(4-hydroxyphenyl) vinyl) pent-2-enal indicated degradation of BPA by two oxidation steps and one ring opening step (C-C bond cleavage). Laccase/RM system exhibited several advantages for the oxidative degradation of hydrophobic phenols mainly because of the solubility of either enzyme or substrate was improved in organic media and the stable activity of laccase in organic media was achieved.

Array-based transcriptional analysis of Clostridium sporogenes UC9000 during germination, cell outgrowth and vegetative life.  

PubMed

The members of the genus Clostridium, including the spore-forming anaerobic bacteria, have a complex and strictly regulated life cycle, but very little is known about the genetic pathways involved in the different stages of their life cycle. Clostridium sporogenes, a Gram-positive bacterium usually involved in food spoilage and frequently isolated from late blowing cheese, is genetically indistinguishable from the proteolytic Clostridium botulinum. As the non-neurotoxic counterpart, it is often used as an exemplar for the toxic subtypes. In this work, we performed a microscopic study combined with a custom array-based analysis of the C. sporogenes cycle, from dormant spores to the early stationary phase. We identified a total of 211 transcripts in spores, validating the hypothesis that mRNAs are abundant in spores and the pattern of mRNA expression is strikingly different from that present in growing cells. The spore transcripts included genes responsible for different life-sustaining functions, suggesting there was transcript entrapment or basic poly-functional gene activation for future steps. In addition, 3 h after the beginning of the germination process, 20% of the total up-regulated genes were temporally expressed in germinating spores. The vegetative condition appeared to be more active in terms of gene transcription and protein synthesis than the spore, and genes coding for germination and sporulation factors seemed to be expressed at this point. These results suggest that spores are not silent entities, and a broader knowledge of the genetic pathways involved in the Clostridium life cycle could provide a better understanding of pathogenic clostridia types.

U.C. Davis particle physics research. Final technical progress report, May 1, 1970--February 28, 1989  

SciTech Connect

During the period of this contract, the participants carried out theoretical and experimental researches in high energy particle physics. The experiment group has been working with both bubble chamber and electronic detectors. The bubble chamber work made use of bubble chambers and particle beams at Lawrence Berkeley Laboratory, Brookhaven National Laboratory, Fermilab, and the Stanford Linear Accelerator Center. The different electronic detectors were the TPC/Two Gamma facility situated at the PEP electron-positron collider at SLAC, the AMY detector at TRISTAN, the electron-positron collider at KEK in Japan, fixed target detectors at Fermilab, and a hybrid bubble chamber/electronic detector at SLAC. Negotiations were also started with the H1 collaboration for a UCD participation at the upcoming Hera electron-proton collider. The theoretical groups have been engaged in a wide variety of studies. Phenomenological studies of high energy interactions have constituted a major fraction of the effort, particularly those associated with the higgs field, various aspects of supersymmetry, and searches for new physics. Work on reactions associated with ee, ep, and hadron colliders has been extensive and includes many analyses providing tests of QCD. Lattice gauge theory has been a major area of work, and electroweak physics and mathematical physics have also been topics of study. Work has been published on heavy flavor decays and CP noninvariance, super symmetry, Yang-Mills theory and electroweak symmetry breaking as well as string theory.

High-resolution seismic reflection/refraction imaging from Interstate 10 to Cherry Valley Boulevard, Cherry Valley, Riverside County, California: implications for water resources and earthquake hazards  

USGS Publications Warehouse

This report is the second of two reports on seismic imaging investigations conducted by the U.S. Geological Survey (USGS) during the summers of 1997 and 1998 in the Cherry Valley area in California (Figure 1a). In the first report (Catchings et al., 1999), data and interpretations were presented for four seismic imaging profiles (CV-1, CV-2, CV-3, and CV-4) acquired during the summer of 1997 . In this report, we present data and interpretations for three additional profiles (CV-5, CV-6, and CV-7) acquired during the summer of 1998 and the combined seismic images for all seven profiles. This report addresses both groundwater resources and earthquake hazards in the San Gorgonio Pass area because the shallow (upper few hundred meters) subsurface stratigraphy and structure affect both issues. The cities of Cherry Valley and Beaumont are located approximately 130 km (~80 miles) east of Los Angeles, California along the southern alluvial fan of the San Bernardino Mountains (see Figure 1b). These cities are two of several small cities that are located within San Gorgonio Pass, a lower-lying area between the San Bernardino and the San Jacinto Mountains. Cherry Valley and Beaumont are desert cities with summer daytime temperatures often well above 100 o F. High water usage in the arid climate taxes the available groundwater supply in the region, increasing the need for efficient management of the groundwater resources. The USGS and the San Gorgonio Water District (SGWD) work cooperatively to evaluate the quantity and quality of groundwater supply in the San Gorgonio Pass region. To better manage the water supplies within the District during wet and dry periods, the SGWD sought to develop a groundwater recharge program, whereby, excess water would be stored in underground aquifers during wet periods (principally winter months) and retrieved during dry periods (principally summer months). The SGWD preferred a surface recharge approach because it could be less expensive than a recharging program based on injection wells. However, at an existing surface recharge site, surface recharge of the aquifer was limited by the presence of clayrich layers that impede the downward percolation of the surface water. In boreholes, these clay-rich layers were found to extend from the near surface to about 50 m depth. If practical, the SGWD desired to relocate the recharge ponds to another location within the Cherry Valley–Beaumont area. This required that sites be found where the clay-rich layers were absent. The SGWD elected to explore for such sites by employing a combination of drilling and seismic techniques. A number of near-surface faults have been suggested in the Cherry Valley-Beaumont area (Figure 1b). However, there may be additional unmapped faults that underlie the alluvial valley of San Gorgonio Pass. Because faults are known to act as barriers to lateral groundwater flow in alluvial groundwater systems, mapped and unmapped subsurface faults in the Cherry Valley-Beaumont area would likely influence groundwater flow and the lateral distribution of recharged water. These same faults may pose a significant hazard to the local desert communities and to greater areas of southern California due to the presence of lifelines (water, electrical, gas, transportation, etc.) that extend through San Gorgonio Pass to larger urban areas. The three principal goals of the seismic investigation presented in this report were to laterally map the subsurface stratigraphic horizons, locate faults that may act as barriers to groundwater flow, and measure velocities of shallow sediments that may give rise to amplified shaking during major earthquakes.

Ground-water conditions in the Anza-Terwilliger area, with emphasis on the Cahuilla Indian Reservation, Riverside County, California, 1973-86  

USGS Publications Warehouse

Demand for groundwater in the 96-sq mi Anza Terwilliger area of California has increased in recent years because of population growth and agricultural development. In order to evaluate the potential effects of continued growth and development on the water resources of Cahuilla Indian Reservation, water level, land use, and water quality data were collected and analyzed. Water level measurements indicate that, as in previous years, groundwater normally moves toward streams in Anza and Terwilliger Valleys. However, during the summer, when pumping is at a maximum, groundwater moves toward two areas of groundwater withdrawal in Anza Valley. One area where groundwater levels were lowered extends to the northern boundary of Cahuilla Indian Reservation. Groundwater use during 1986 is estimated at 10,000 acre-ft, 6,000 acre-ft more than in 1973. The water table, however, generally has risen since 1973 due to the wet climatic conditions that generally have prevailed since 1976. Dissolved-solids concentrations during 1984-86 ranged from 184 to 1,320 mg/L. Water from two wells on Cahuilla Indian Reservation had dissolved-solids concentrations higher than the U.S. Environmental Protection Agency recommended limit for drinking water of 500 mg/L. No wells sampled on the reservation contained water with nitrate concentrations above the U.S. Environmental Protection Agency recommended limit of 10 mg/L. The observation-well network was found to be generally adequate, but the addition of one water level and two water quality observation wells would enhance its effectiveness. (USGS)

Occupational exposure of workers to ethylene oxide (EtO) was examined. Two of six side-by-side short-term personal breathing-zone (BZ) exposure levels, determined while the sterilizer operator unloaded the EtO sterilizer unit, exceeded NIOSH recommended short term levels of 5 parts per million (ppm) for any 10-minute period per workday. Three of 12 personal BZ exposure levels exceeded the NIOSH recommended standard of less than 0.1ppm for an 8-hour time-weighted average. Measurable levels of EtO, ranging from 0.18 to 14.5ppm were detected in the storage room where the EtO sterilized items were aerated. The authors conclude that EtO exposure potential at the nursing and rehabilitation center could be reduced by improving administrative controls, work practices, and engineering controls. Recommended improvements were given.

The Casimir effect is important in various fields from atomic physics to nanotechnology. According to the Lifshitz theory of the Casimir force, the interaction between two objects depends both on their dielectric permittivity and magenetic permeability. Thus the role of magnetic properties on the Casimir force is interesting particularly due to the possibility of a reduction the Casimir force. In this report we will present the results of a Casimir force measurement between a magnetic material such as nickel coated on SiO2 plate and a Au-coated sphere.

Trace elements in fine particulate matter within a community in western Riverside County, CA: focus on residential sites and a local high school  

NASA Astrophysics Data System (ADS)

Measurements of mass concentrations of 35 trace elements (TEs) and of total fine particulate matter (PM 2.5) were conducted at 20 residences and six high school rooms in Mira Loma, California, from September 2001 to January 2002. Sulfur (S) and silicon (Si) were the most abundant TEs measured (excluding a residence with heavy smokers). On average, total TE concentrations were lower indoors relative to outdoors; the proportion of TEs in total PM 2.5 was also lower indoors relative to outdoors. Among indoor sites, TE concentrations were found to be lower inside the schoolrooms relative to inside the residences. Environmental tobacco smoke (ETS) was found to contribute significantly to elevated levels of total TE inside residences; however, concentrations of carcinogenic TEs were not significantly different between residences with and without smokers. Potassium (K) and chlorine (Cl) were the most abundant species in a residence with frequent indoor smokers. Combustion-related elements were more enriched inside the residences relative to crustal elements.

Institute of Geophysics and Planetary Physics, Lawrence Livermore National Laboratory, 1996 Annual Report  

SciTech Connect

The Institute of Geophysics and Planetary Physics (IGPP) is a Multicampus Research Unit of the University of California (UC). IGPP was founded in 1946 at UC Los Angeles with a charter to further research in the earth and planetary sciences and in related fields. The Institute now has branches at UC campuses in Los Angeles, San Diego, and Riverside, and at Los Alamos and Lawrence Livermore national laboratories. The University-wide IGPP has played an important role in establishing interdisciplinary research in the earth and planetary sciences. For example, IGPP was instrumental in founding the fields of physical oceanography and space physics, which at the time fell between the cracks of established university departments. Because of its multicampus orientation, IGPP has sponsored important interinstitutional consortia in the earth and planetary sciences. Each of the five branches has a somewhat different intellectual emphasis as a result of the interplay between strengths of campus departments and Laboratory programs. The IGPP branch at Lawrence Livermore National Laboratory (LLNL) was approved by the Regents of the University of California in 1982. IGPP-LLNL emphasizes research in seismology, geochemistry, cosmochemistry, and astrophysics. It provides a venue for studying the fundamental aspects of these fields, thereby complementing LLNL programs that pursue applications of these disciplines in national security and energy research. IGPP-LLNL is directed by Charles Alcock and was originally organized into three centers: Geosciences, stressing seismology; High-Pressure Physics, stressing experiments using the two-stage light-gas gun at LLNL; and Astrophysics, stressing theoretical and computational astrophysics. In 1994, the activities of the Center for High-Pressure Physics were merged with those of the Center for Geosciences. The Center for Geosciences, headed by Frederick Ryerson, focuses on research in geophysics and geochemistry. The Astrophysics Research Center, headed by Charles Alcock, provides a home for theoretical and observational astrophysics and serves as an interface with the Physics and Space Technology Department's Laboratory for Experimental Astrophysics and with other astrophysics efforts at LLNL. The IGPP branch at LLNL (as well as the branch at Los Alamos) also facilitates scientific collaborations between researchers at the UC campuses and those at the national laboratories in areas related to earth science, planetary science, and astrophysics. It does this by sponsoring the University Collaborative Research Program (UCRP), which provides funds to UC campus scientists for joint research projects with LLNL. The goals of the UCRP are to enrich research opportunities for UC campus scientists by making available to them some of LLNL's unique facilities and expertise, and to broaden the scientific program at LLNL through collaborative or interdisciplinary work with UC campus researchers. UCRP funds (provided jointly by the Regents of the University of California and by the Director of LLNL) are awarded annually on the basis of brief proposals, which are reviewed by a committee of scientists from UC campuses, LLNL programs, and external universities and research organizations. Typical annual funding for a collaborative research project ranges from $5,000 to $25,000. Funds are used for a variety of purposes, including salary support for visiting graduate students, postdoctoral fellows, and faculty; released-time salaries for LLNL scientists; and costs for experimental facilities. Although the permanent LLNL staff assigned to IGPP is relatively small (presently about five full-time equivalents), IGPP's research centers have become vital research organizations. This growth has been possible because of IGPP support for a substantial group of resident postdoctoral fellows; because of the 20 or more UCRP projects funded each year; and because IGPP hosts a variety of visitors, guests, and faculty members (from both UC and other institutions) on sabbatical leave.

Hourly In-Situ Measurements of Organic Aerosol Speciation by Thermal desorption Aerosol GC/MS-FID (TAG): Advances in Calibration Procedures  

NASA Astrophysics Data System (ADS)

Thermal desorption Aerosol GC/MS-FID (TAG) provides a novel means of obtaining hourly in-situ measurements of organic aerosol speciation. In a typical chromatogram, hundreds to thousands of organic compounds may be present, making careful compound identification and calibration practices a critical part of obtaining reliable and useful data. This presentation will focus on a series of field calibrations performed during sampling of ambient aerosols using the TAG instrument. TAG couples inertial collection of fine particulates with diameters between 0.1 and 2.5 ?m and analysis via gas phase chromatography and mass spectrometry following thermal desorption of a sample. This combined collection and analysis system provides hourly speciation of a wide range of organic compounds that is limited only by the compatibility of the GC column (DB-5MS) and feasible temperature range (50-300 °C). The direct introduction of thermally desorbed species into the GC/MS-FID avoids sample handling artifact concerns and costly analytical sample processing. A modified collection cell was introduced to the system that allows direct, in-situ injections of compound standards to calibrate and monitor the performance of the instrument. An evaluation of this approach is presented using results from UC Berkeley laboratory studies and a 5 week urban aerosol study in Riverside, California conducted July-August, 2005 as part of the Study of Organic Aerosols in Riverside (SOAR) campaign. Examples are given where the retention times of a large selection of compounds used as injection standards assisted in the positive identification and quantitation of organic species in ambient aerosols.

The Role of Ethnographic Interviewing in Climate Change Evaluation Research: Investigating Intended and Unintended program effects  

NASA Astrophysics Data System (ADS)

Ethnographic interviewing is an under-utilized tool in climate change evaluation research, even though it has the potential to serve as a powerful method of data collection. The utility of the ethnographic interview lies in its ability to elicit responses from program participants describing what a program is in practice, shedding light on both intended and unintended program impacts. Drawing on evaluation work involving a federally-funded climate change grant at the University of California, Riverside, I will discuss how to design an ethnographic interview protocol in an effort to share "best practices" with other climate change evaluators. Particular attention will be given to applying ethnographic approaches to various program types, even those differing from the one discussed. I will share some of the concrete findings from my work on this grant, to serve as examples of the kinds of data evaluators can collect when employing an ethnographic approach to interviewing. UC Riverside's climate change grant is multi-faceted, however the component studied ethnographically was a science fair mentoring program. About twenty K-12 students from high poverty, ethnically diverse schools who expressed an interest in participating in science fair were paired up with graduate student mentors to simultaneously research climate change and design authentic science fair projects to compete at various levels. Since one of the stated goals of the grant is to "stimulate…students to consider climate science as a career track through experiential education activities" I was particularly interested in how student experiences with the project might differ from school science which has historically "pushed out" ethnically diverse students like those in many of Riverside's schools. (In the program students are able to interact one-on-one with a mentor and in school settings there is typically one teacher for more than thirty students). I also sought to understand student perceptions of the project design and implementation and how these perceptions might influence their thinking about science as a career. Further, I aimed to explore how mentor pedagogical philosophies might impact student experiences with the projects, since the scholarly literature supports the idea that teaching practices are linked to student success and interest in science. The key to ethnographic interviewing, which sets it apart from survey research and other interviewing styles is that the evaluator or researcher designs guided, yet open-ended questions, allowing informants to discuss what is important to them. This type of questioning affords the researcher the opportunity to ascertain whether or not the grant met some of its intended goals and impacts, while simultaneously granting participants the freedom to discuss unintended impacts not anticipated by the principal investigator and evaluator.

The Campi Flegrei caldera: historical revision and new data on seismic crises, bradyseisms, the Monte Nuovo eruption and ensuing earthquakes (twelfth century 1582 uc(ad))  

NASA Astrophysics Data System (ADS)

This paper presents the results of a systematic historical study of the seismic, bradyseismic and eruptive activity of the Campi Flegrei caldera. The aim is to make a revised historical data available for accurate volcanological interpretation, supplying additional data and highlighting spurious previous data. The analysis begins with the supposed 1198 eruption, which did not actually take place. No information is available for the thirteenth and fourteenth centuries. As far as the fifteenth and sixteenth centuries are concerned, only direct sources were examined for this paper, and they include many different types of evidence. The chronological breadth of the analysis has also provided information about the seismic crises and bradyseisms prior to the eruption of 1538. The exceptional nature of this 1538 eruption attracted the attention of intellectuals, diplomats and natural philosophers, who left valuable accounts, which we have analysed, and which include many that are still available in their original manuscript form. The previous studies concerning the 1538 eruption were based on 23 (variously used) sources. We have examined 35 additional sources bringing the overall corpus of sources analysed to 58. The results provide a more precise scenario of events preceding the 1538 eruption, including bradyseismic activity starting from the end of the fifteenth century. The chronology of the phenomena described comprises the core result of this study, and has been constructed so as to clarify the time, location and impact of each event. For the 1538 eruption, a countdown is included which may also have a predictive value. For the last 36 hours before eruption began, the countdown is hour-by-hour. The effects of the eruption and earthquakes on people, structures and society are also described for Pozzuoli, Agnano and Naples. The areas where heavy materials and ash fell are likewise indicated, as well are the earth tremors felt by the population from the eruptive crisis up to 1582.

Evaluation of Type I cement sorbent slurries in the U.C. pilot spray dryer facility. Final report, November 1, 1994--February 28, 1996  

SciTech Connect

This research was focused on evaluating hydrated cement sorbents in the U. C. pilot spray dryer. The main goal of this work was to determine the hydration conditions resulting in reactive hydrated cement sorbents. Hydration of cement was achieved by stirring or by grinding in a ball mill at either room temperature or elevated temperatures. Also, the effects of several additives were studied. Additives investigated include calcium chloride, natural diatomite, calcined diatomaceous earth, and fumed silica. The performance of these sorbents was compared with conventional slaked lime. Further, the specific surface area and pore volume of the dried SDA sorbents were measured and compared to reactivity. Bench-scale tests were performed to obtain a more detailed picture of the development of the aforementioned physical properties as a function of hydration time.

Quake-Catcher Network (QCN), a distributed computing project initiated by Stanford University and UC Riverside, encourages the volunteers to install the low-cost, novel sensors at home and school to build a seismic network. To meet both needs, we have developed a model curriculum that introduces QCN, earthquake science, and cloud computing into high school classrooms. Through professional development workshops, Taiwan cloud-based earthquake science learning platform, and QCN club on Facebook, we have worked closely with Lan-Yang Girl's Senior High School teachers' team to design workable teaching plans through a practical operation of seismic monitoring at home or school. However, some obstacles to learning appear including QCN installation/maintain problems, high self-noise of the sensor, difficulty of introducing earthquake sciences for high school teachers. The challenges of QCN outreach in Taiwan bring out our future plans: (1) development of easy, frequently updated, physics-based QCN-experiments for high school teachers, and (2) design of an interactive learning platform with social networking function for students.

High energy physics at UCR  

SciTech Connect

The hadron collider group is studying proton-antiproton interactions at the world`s highest collision energy 2 TeV. Data-taking with the D0 detector is in progress at Fermilab and the authors have begun the search for the top quark. S. Wimpenny is coordinating the effort to detect t{bar t} decaying to two leptons, the most readily identifiable channel. At UC Riverside design and testing for a silicon tracker for the D0 upgrade is in progress; a parallel development for the SDC detector at SSC is also underway. The major group effort of the lepton group has been devoted to the OPAL experiment at LEP. They will continue to focus on data-taking to improve the quality and quantity of their data sample. A large number of papers have been published based on approximately 500,000 events taken so far. The authors will concentrate on physics analysis which provides stringent tests of the Standard Model. The authors are continuing participation in the RD5 experiment at the SPS to study muon triggering and tracking. The results of this experiment will provide critical input for the design of the Compact Muon Solenoid experiment being proposed for the LHC. The theory group has been working on problems concerning the possible vilation of e-{mu}-{tau} universality, effective Lagrangians, neutrino physics, as well as quark and lepton mass matrices.

Advances in genome studies in plants and animals.  

PubMed

The area of plant and animal genomics covers the entire suite of issues in biology because it aims to determine the structure and function of genetic material. Although specific issues define research advances at an organism level, it is evident that many of the fundamental features of genome structure and the translation of encoded information to function share common ground. The Plant and Animal Genome (PAG) conference held in San Diego (California), in January each year provides an overview across all organisms at the genome level, and often it is evident that investments in the human area provide leadership, applications, and discoveries for researchers studying other organisms. This mini-review utilizes the plenary lectures as a basis for summarizing the trends in the genome-level studies of organisms, and the lectures include presentations by Ewan Birney (EBI, UK), Eric Green (NIH, USA), John Butler (NIST, USA), Elaine Mardis (Washington, USA), Caroline Dean (John Innes Centre, UK), Trudy Mackay (NC State University, USA), Sue Wessler (UC Riverside, USA), and Patrick Wincker (Genoscope, France). The work reviewed is based on published papers. Where unpublished information is cited, permission to include the information in this manuscript was obtained from the presenters. PMID:24626952

Secondary organic aerosol formation from primary aliphatic amines with NO3 radical  

NASA Astrophysics Data System (ADS)

Primary aliphatic amines are an important class of nitrogen containing compounds emitted from automobiles, waste treatment facilities and agricultural animal operations. A series of experiments conducted at the UC-Riverside/CE-CERT Environmental Chamber is presented in which oxidation of methylamine, ethylamine, propylamine, and butylamine with O3 and NO3 have been investigated. Very little aerosol formation is observed in the presence of O3 only. However, after addition of NO, and by extension NO3, large aerosol mass yields (~44% for butylamine) are seen. Aerosol generated was determined to be organic in nature due to the small fraction of NO and NO2 in the total signal (<1% for all amines tested) as detected by an aerosol mass spectrometer (AMS). We propose a reaction mechanism between carbonyl containing species and the parent amine leading to formation of particulate imine products. These findings can have significant impacts on rural communities with elevated nighttime PM loadings, when significant levels of NO3 exist.

Frozen Deuterium Cylindrical Target System for PBFA Z and Shiva Star  

NASA Astrophysics Data System (ADS)

AFRL, in conjunction with UC, Riverside, is perfecting a system for delivering round cylindrical fiber fragments of frozen D2 with diameters up to 1 mm to the central load region of SNL's PBFA Z and AFRL's Shiva Star capacitor bank. On Z, the intention is for the fiber to be shock heated by a wire array implosion to produce neutrons. On Shiva, the fiber is intended to serve as a plasma source to increase the density of a compact toroid or FRC prior to compression as one Magnetized Target Fusion geometry to be explored at AFRL. Operationally, a D2 fiber is first extruded by AFRL's closed cycled refrigerated frozen gas extruder. A few cm length of fiber is then cut off. The fragment falls into a funnel which guides it through LN2 refrigerated orifices above and below the load region. The fiber is prevented from falling all the way through the orifices by a thin Kapton(TM) foil a few mm below the lower orifice. The fiber is self-centering within the orifices due to D2 sublimation pressure effects. The supporting foil is LN2 cooled at its edges, but locally cools further due to contact with the tip of the fiber. A hydraulically activated blast shutter is closed after fiber delivery to protect the extruder from the energetic events which follow.

Experimentally measured morphology of biomass burning aerosol and its impacts on CCN ability  

NASA Astrophysics Data System (ADS)

This study examines the morphological properties of freshly emitted and atmospherically aged aerosols from biomass burning. The impacts of particle morphology assumptions on hygroscopic predictions are examined. Chamber experiments were conducted at the UC-Riverside Center for Environmental Research and Technology (CE-CERT) Atmospheric Processes Lab using two biomass fuel sources, manzanita and chamise. Morphological data was obtained through the use of an aerosol particle mass analyzer (APM), scanning mobility particle sizer (SMPS) system and transmission electron microscopy (TEM). Data from these instruments was used to calculate both a dynamic shape factor and a fractal-like dimension for the biomass burning emissions. This data was then used with ?-Köhler theory to adjust the calculated hygroscopicity for experimentally determined morphological characteristics of the aerosol. Laboratory measurement of biomass burning aerosol from two chaparral fuels show that particles are non-spherical with dynamic shape factors greater than 1.15 for aerosol sizes relevant to cloud condensation nuclei (CCN) activation. Accounting for particle morphology can shift the hygroscopicity parameter ? by 0.15 or more. To our knowledge, this work provides the first laboratory chamber measurements of morphological characteristics for biomass burning cloud condensation nuclei and provides experimental particle shape evidence to support the variation in reported hygroscopicities of the complex aerosol.

Red Planet? Red River!FIELD Works on the Red-Mud Flood Polluted Marcal Riverside: ph Measurements by the HUSAR-5 Nxt-Based Rover Model of the SZÉCHENYI ISTVÁN High School, Sopron, Hungary.  

NASA Astrophysics Data System (ADS)

On October 4, 2010, heavy industrial catastrophe polluted the Marcal river in West-Hungary. The Red-mud sludge, the byproduct of the alumina production, poured from a containment pond because of the broken dike. The environmental pollution first appeared in the creeks and rivers in the vicinity of the alumina plant at Ajka. Earlier our group prepared pH measurement robotics on the HUSAR-5 rover therefore our idea was to carry out - a planetary analog type - field works with the rover on the polluted region. The locality was about 100 kilometrs from our town, Sopron. We visited 3 times the region.

Visible and near-IR spectroscopic studies of UC1{sub 4} in a basic ambient temperature melt: The observation of a possible geometric distorted UC1{sub 6}{sup 2{minus}} species and the evidence for the hydrogen-bond in the melt  

SciTech Connect

Since high temperatures can lead to broadening of absorption spectra, ambient temperature chloride melts were used; the system used was AlCl{sub 3}-1-ethyl-3-methyl-imidazolium chloride (EMIC). The uv-visible spectrum of UCl{sub 4} in basic melt had many peaks with the most intense (triplet) ones around 2000 nm, similar to these at high temperature and indicating the same species. The electronic transition is allowed by a static rather than a vibronic mechanism. The central peak in the UCl{sub 6}{sup 2-} spectrum indicates distortion of geometry from the O{sub h} symmetry by the solvent medium. Very strong hydrogen bonding between UCl{sub 6}{sup 2-} and solvent EMI is suggested.

Satellite Sensornet Gateway Technology Infusion Through Rapid Deployments for Environmental Sensing  

NASA Astrophysics Data System (ADS)

The Satellite Sensornet Gateway (SSG) is an ongoing ESTO Advanced Information Systems Technology project, at the University of Southern California. The major goal of SSG is to develop a turnkey solution for building environmental observation systems based on sensor networks. Our system has been developed through an iterative series of deployment-driven design, build, test, and revise which maximizes technology infusion to the earth scientist. We have designed a robust and flexible sensor network called Sensor Processing and Acquisition Network (SPAN). Our SPAN architecture emphasizes a modular and extensible design, such that core building blocks can be reused to develop different scientific observation systems. To support rapid deployment at remote locations, we employ satellite communications as the backhaul to relay in-situ sensor data to a central database. To easily support various science applications, we have developed a unified sensor integration framework that allows streamlined integration of different sensors to the system. Our system supports heterogeneous sets of sensors, from industry-grade products to research- specific prototypes. To ensure robust operation in harsh environments, we have developed mechanisms to monitor system status and recover from potential failures along with additional remote configuration and QA/QC functions. Here we briefly describe the deployments, the key science missions of the deployments and the role that the SSG technology played in each mission. We first deployed our SSG technology at the James Reserve in February 2007. In a joint deployment with the NEON project, SDSC, and UC Riverside, we set up a meteorological station, using a diverse set of sensors, with the objective of validating our basic technology components in the field. This system is still operational and streaming live sensor data. At Stunt Ranch, a UC Reserve near Malibu, CA, we partnered with UCLA biologist Phillip Rundel in order to study the drought impact on deep and shallow rooted plants. Our system was deployed in December 2007 and monitors sap flow on various plant species, while using a satellite link for real-time data access. In April 2008, in a joint deployment with UCLA, UC Merced, and GLEON, our SSG technology was used to study the impact of agricultural run off in a series of salt lakes near Bahia Blanca, Argentina. Our system collected meteorological data that were combined with water quality measurements taken from boats and buoys. Our SSG technology was used at the PASI workshop in June 2008 at the La Selva Biological Research Station in Costa Rica. As part of a two-week curriculum, students from throughout the americas used our system to collect measurements in the rain forest and later analyzed the data. La Selva plans to install several SSG nodes throughout the reserve and make mobile nodes available for visiting researchers to use in their research. We are currently planning a deployment with environmental engineer Tom Harmon from UC Merced to build an autonomous water quality flow path and reactive transport observation system near Merced, CA. SSG technology will be deployed to monitor soil, groundwater, and surface water parameters. In China's Guizhou Province, we are collaborating with researcher Sarah Rothenberg, who is studying mercury cycling in rice paddies. Our SSG system will collect soil parameters such as pH and ORP, in addition to environmental measurements such as PAR, and UV. This presentation will describe the SSG project, the SPAN prototype and our experience with technology infusion from the deployments. class="ab'>

Precise Relocation of the Northern Extent of the Aftershock Sequence Following the 4 April 2010 M7.2 El Mayor-Cucapah Earthquake Kayla A. Kroll (UCR) and Elizabeth S. Cochran (UCR)  

NASA Astrophysics Data System (ADS)

Following the 4 April 2010 M7.2 El Mayor-Cucapah earthquake, teams from UC Riverside, UC Santa Barbara, and San Diego State University installed an array of 8 temporary seismometers in the Yuha Desert area north of the Mexican border. This temporary array complemented the existing network stations and continuously recorded data from the aftershock sequence from 6 April through 14 June 2010. SCSN and the temporary aftershock array data will be used to study several aspects of fault structure and behavior, including precise relocation of the aftershock sequence. While the mainshock sequence ruptured multiple fault strands west of the Cerro Prieto fault, and south of the Sierra Cucapah Range, the aftershocks are densely clustered in three areas. The largest cluster is located to the northwest of the mainshock, in an area with no previously mapped faults. By relocating aftershocks, we hope to illuminate the network of faults that extend from the Laguna Salada fault in Mexico to its northern extension towards the Elsinore and San Jacinto faults. Right-lateral displacements up to 2 cm were identified on several right- and left-lateral fault segments by the USGS/CGS geologists in the area south of Hwy 98, and into the Pinto Wash (Treiman et al., personal communication, 2010). We relocate aftershocks within a 20 km by 14 km region containing 1 network and 8 temporary stations. Within this region over 4,000 aftershocks are in the SCEDC catalog from 6 April to 14 June 2010, during the time the temporary network was installed. The P and S wave arrival times for both the network and temporary stations were manually picked for each of these events. We compute the double difference hypocenter locations using the picked phase arrivals and waveform cross-correlations in the hypocenter relocation program, hypoDD (Waldhauser & Ellsworth 2000). In the event relocation, we used the velocity profile for the Imperial Valley from the SCEC Unified Velocity Model (Version 4). Future work will include detecting and relocating events that are not in the SCEDC catalog using the continuous data from the temporary array. All of the data will then be relocated using waveform cross-correlation in hypoDD to further improve the locations. Since little is known about the fault structure in the Yuha Desert region, we hope that accurate earthquake locations will help illuminate the complex and unmapped fault structure in the area. Additionally, more precise earthquake depths will help determine the extent of the seismogenic zone.

Climate Change, NASA and New Media: Engaging Non-Science Undergraduates in Climate Science Education  

NASA Astrophysics Data System (ADS)

UC Riverside is one of the most socioeconomically and ethnically diverse university campuses in the country. As one of only two federally-designated Hispanic Serving Research Institutions, UCR has long been committed to successfully educating and graduating Latino students in science, technology, engineering and math (STEM) fields (fields in which Latino students are severely under-represented). Because Latinos are the fastest growing ethnic minority in the country, educating Latino students in climate science is necessary for creating an educated and informed American society. Each year nearly 3000 undergraduate students take lower-division courses in the UCR Earth Sciences Department. This creates a unique opportunity to educate a broad cross-section of students from all fields and majors in societally-important Earth Science issues. As part of a NASA Global Climate Change Education grant, the Earth Sciences Department has restructured its lower-division courses to emphasize climate science by redesigning labs and activities that incorporate online NASA climate data, with the idea that first-hand analysis of data will provide students with a better understanding of the complexities of climate change. While NASA data and resources are being woven in all lower-division courses, one course in particular, "Global Climate Change," has been completely redesigned: this course now both examines the science of climate change and trains students in the articulation of climate science. Students learn to use new medial like YouTube to create and disseminate their own educational vidoes. The goal of this approach is to educate all students, not just those studying Earth Sciences, and to ultimately increase the general public's understanding of global climate change.

Characterization of PM-PEMS for in-use measurements conducted during validation testing for the PM-PEMS measurement allowance program  

NASA Astrophysics Data System (ADS)

This study provides an evaluation of the latest Particulate Matter-Portable Emissions Measurement Systems (PM-PEMS) under different environmental and in-use conditions. It characterizes four PM measurement systems based on different measurement principles. At least three different units were tested for each PM-PEMS to account for variability. These PM-PEMS were compared with a UC Riverside's mobile reference laboratory (MEL). PM measurements were made from a class 8 truck with a 2008 Cummins diesel engine with a diesel particulate filter (DPF). A bypass around the DPF was installed in the exhaust to achieve a brake specific PM (bsPM) emissions level of 25 mg hp-1h-1. PM was dominated by elemental carbon (EC) during non-regeneration conditions and by hydrated sulfate (H2SO4.6H2O) during regeneration. The photo-acoustic PM-PEMS performed best, with a linear regression slope of 0.90 and R2 of 0.88 during non-regenerative conditions. With the addition of a filter, the photo-acoustic PM-PEMS slightly over reported than the total PM mass (slope = 1.10, R2 = 0.87). Under these same non-regeneration conditions, a PM-PEMS equipped with a quartz crystal microbalance (QCM) technology performed the poorest, and had a slope of 0.22 and R2 of 0.13. Re-tests performed on upgraded QCM PM-PEMS showed a better slope (0.66), and a higher R2 of 0.25. In the case of DPF regeneration, all PM-PEMS performed poorly, with the best having a slope of 0.20 and R2 of 0.78. Particle size distributions (PSD) showed nucleation during regeneration, with a shift of particle size to smaller diameters (˜64 nm to ˜13 nm) with elevated number concentrations when compared to non-regeneration conditions.

Neural substrates for expectation-modulated fear learning in the amygdala and periaqueductal gray  

Microsoft Academic Search

A form of aversively motivated learning called fear conditioning occurs when a neutral conditioned stimulus is paired with an aversive unconditioned stimulus (UCS). UCS-evoked depolarization of amygdala neurons may instruct Hebbian plasticity that stores memories of the conditioned stimulus–unconditioned stimulus association, but the origin of UCS inputs to the amygdala is unknown. Theory and evidence suggest that instructive UCS inputs

Late-Onset Distant Metastatic Upper Urinary Tract Urothelial Carcinoma Mimicking Lung Adenocarcinoma  

PubMed Central

Urothelial carcinomas (UCs) can occur in the upper urinary tract or lower urinary tract. Upper urinary tract urothelial carcinoma (UUT-UC) is relatively a rare disease and accounts for only about 5% of UC cases. Sporadic cases of late-onset metastasis, associated with UC of the bladder, have occasionally been reported. In contrast, no late-onset distant metastatic UUT-UC without local recurrence has, to the best of our knowledge, been reported in the English literature. We report an extremely rare case of distant metastatic UC, mimicking lung adenocarcinoma that originated from UUT-UC 12 years previously.

[Status of hemapoiesis in residents of the Techa riverside villages in the period of maximum radiation exposure. Report 2. Influence of exposure dose and dose rate of red bone marrow as well as modifying factors on the frequency of cytopenia and cytosis].  

PubMed

The purpose of this study is a retrospective estimation of the influence of dose and dose rate of the red bone marrow chronic radiation exposure in combination with various modifying factors (gender, age, comorbidity) on the frequency of deviations from normal values of the results of peripheral blood investigation in humans exposed on the Techa River. The results of investigation show that humans chronically exposed to radiation can develop marked changes in the cellular composition of peripheral blood characterized by a tendency to cytopenia (signs of the decompensation of hemopoiesis). The tendency to cytopenia can be identified earlier in the lymphoid germ, and later in platelet and erythroid lines. A high lability of granulocytes under the influence of various, often infectious, factors is the cause of the lack of statistically significant differences in terms of frequency of neutropenia. Several non-radiation factors (gender, age, health status) in combination with radiation exposure could have a modifying influence on hematopoiesis, which contributed to the disruption of adaptation processes and the development of conditions characterized by a tendency to cytopenias in exposed individuals. The red bone marrow dose rate reduction resulted in a gradual decrease in the frequency of erythrocytopenia, thrombocytopenia, neutropenia and lymphocytopenia in the group of exposed population. Increased frequencies of erythrocytosis, thrombocytosis, lymphocytosis, monocytosis and neutrophilia were observed when the median dose rate was reduced to the level of 0.024 Gy/year (in the year 1956), which could be regarded as activation of regenerative processes in hematopoiesis.

Modulation of phospholipid metabolism in murine keratinocytes by tumor promoter, 12-O-tetradecanoylphorbol-13-acetate  

SciTech Connect

The possibility that phospholipid deacylation may be a critical event in the 12-O-tetradecanoylphorbol-13-acetate (TPA)-associated effects on mouse skin prompted us to examine in vitro the effects of TPA on arachidonic acid metabolism in neonatal mouse keratinocytes. Three-day old neonatal keratinocytes were prelabeled with ( UC)arachidonic acid (( UC)AA) and ( UC) stearic acid (( UC)ST) and used to characterize the lipases that were activated when these cells were treated with TPA in culture. Data from these studies demonstrate that phosphatidylcholine (PC) and phosphatidylinositol (PI) are the major phospholipids that undergo early hydrolysis to release arachidonic acid when challenged by TPA. Of particular interest was the novel observation of the hydrolysis of UC-labeled PI in these keratinocytes, the accumulation of ( UC)1,2-diacylglyceride and the lack of the ( UC)diacylglyceride phosphorylation to form ( UC)phosphatidic acid. This lack of ( UC) phosphatidic accumulation implied that although TPA enhanced the hydrolysis of ( UC)PI resulting in increased ( UC)diacylglyceride it did not enhance the resynthesis of the ( UC)PI via the phosphorylation of the ( UC)diacylglyceride. Therefore, TPA probably is not involved in the turnover of PI in these cells but is involved in the activation of PC hydrolyzing phospholipase A2 and PI hydrolyzing phospholipase C in these keratinocytes releasing arachidonic acid which then undergoes oxygenation reactions to provide biologically active eicosanoids.

Ulcerative Colitis and Immunoglobulin G4  

PubMed Central

Background/Aims Ulcerative colitis (UC) is sometimes associated with autoimmune pancreatitis (AIP). Infiltration of immunoglobulin G4 (IgG4)-positive plasma cells is sometimes detected in the colonic mucosa of AIP or UC patients. This study aimed to clarify the relation between UC and IgG4. Methods Associations with UC were reviewed in 85 AIP patients. IgG4 immunostaining was performed on biopsy specimens from the colonic mucosa of 14 AIP and 32 UC patients. Results UC was confirmed in two cases (type 1 AIP, n=1; suspected type 2 AIP, n=1). Abundant infiltration of IgG4-positive plasma cells in the colonic mucosa was detected in the case of suspected type 2 AIP with UC and two cases of type 1 AIP without colitis. Abundant infiltration of IgG4-positive plasma cells was detected in 10 UC cases (IgG4-present, 31%). Although 72% of IgG4-absent UC patients showed mild disease activity, 70% of IgG4-present patients showed moderate to severe disease activity (p<0.05). Conclusions UC is sometimes associated with AIP, but it seems that UC is not a manifestation of IgG4-related disease. Infiltration of IgG4-positive plasma cells is sometimes detectable in the colonic mucosa of UC patients and is associated with disease activity.

Takayasu arteritis associated with ulcerative colitis and optic neuritis: first case in Korea

Takayasu arteritis (TA) is a chronic vasculitis that affects the aortic arch and its primary branches. Ulcerative colitis (UC) is an inflammatory bowel disease of unknown etiology. Patients diagnosed with both TA and UC have rarely been reported. The pathogenesis of TA and UC is uncertain, but cell-mediated mechanisms play an important role in both diseases, and a genetic factor is thought to have an effect on the coincidence of these two diseases. We herein report a 38-year-old female with TA who had a history of UC with optic neuritis. We believe that this is the first case of the coexistence of TA and UC in Korea.

Gutzwiller Method for an Extended Periodic Anderson Model with the c--f Coulomb Interaction  

NASA Astrophysics Data System (ADS)

We study an extended periodic Anderson model with the Coulomb interaction Uc\\aku f between conduction and f electrons by the Gutzwiller method. The crossovers between the Kondo, intermediate-valence, and almost empty f-electron regimes become sharper with Uc\\aku f, and for a sufficiently large Uc\\aku f, become first-order phase transitions. In the Kondo regime, a large enhancement in the effective mass occurs as in the ordinary periodic Anderson model without Uc\\aku f. In addition, we find that a large mass enhancement also occurs in the intermediate-valence regime by the effect of Uc\\aku f.

U.C. Berkeley Nuclear Engineering curriculum and research enhancement. Final report for award DE-FG03-94ER-76010 and progress report for award DE-FG03-95NE-38105, February 15, 1993--September 29, 1996  

SciTech Connect

This report discusses the progress achieved during the multi-year program for curriculum and research enhancement for the Department of Nuclear Engineering at the University of California, Berkeley. Due to its declining utility for research, six years ago the department decommissioned the TRIGA research reactor, to make the space available for an accelerator-driven rotating target neutron source for fusion studies. The DOE has traditionally supported these university reactors, in part because they provide a vital educational experience for undergraduate students in reactor operations. Thus in 1993 the department was determined to use its DOE award to replace the undergraduate education that the research reactor formerly provided with an equal or superior educational experience. As this progress report indicates, they can now make a compelling argument that the effort has been successful. Students now have the opportunity to spend a full week at the Diablo Canyon Nuclear Power Plant, after spending two weeks full time at Berkeley studying plant operations. The students spend a full day operating the plant using the full-scale simulator, spend a day each individually and in small groups with operations and engineering personnel, and by the end of the week are intimately familiar with the basics of nuclear power plant operations, at a depth that can not be achieved with a university research reactor. A primary mission for nuclear engineering departments will remain the education of the engineers who will be responsible for the safe operation of the nation`s existing nuclear power plants. In the past, university research reactors have provided a crucial element in that education. As more research reactors are decommissioned in response to evolving research needs, the program developed may serve as a useful model for other nuclear engineering departments.

Dysregulated Circulating Dendritic Cell Function in Ulcerative Colitis Is Partially Restored by Probiotic Strain Lactobacillus casei Shirota  

PubMed Central

Background. Dendritic cells regulate immune responses to microbial products and play a key role in ulcerative colitis (UC) pathology. We determined the immunomodulatory effects of probiotic strain Lactobacillus casei Shirota (LcS) on human DC from healthy controls and active UC patients. Methods. Human blood DC from healthy controls (control-DC) and UC patients (UC-DC) were conditioned with heat-killed LcS and used to stimulate allogeneic T cells in a 5-day mixed leucocyte reaction. Results. UC-DC displayed a reduced stimulatory capacity for T cells (P < 0.05) and enhanced expression of skin-homing markers CLA and CCR4 on stimulated T cells (P < 0.05) that were negative for gut-homing marker ?7. LcS treatment restored the stimulatory capacity of UC-DC, reflecting that of control-DC. LcS treatment conditioned control-DC to induce CLA on T cells in conjunction with ?7, generating a multihoming profile, but had no effects on UC-DC. Finally, LcS treatment enhanced DC ability to induce TGF? production by T cells in controls but not UC patients. Conclusions. We demonstrate a systemic, dysregulated DC function in UC that may account for the propensity of UC patients to develop cutaneous manifestations. LcS has multifunctional immunoregulatory activities depending on the inflammatory state; therapeutic effects reported in UC may be due to promotion of homeostasis.
