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.

The CBD for Botanists  

NSDL National Science Digital Library

One of the two conventions signed at the Earth Summit in Rio de Janeiro in 1992, the Convention on Biological Diversity (CBD) seeks to "conserve biological diversity, use biological resources sustainably -- to ensure that we do not use up our resources faster than they can recover, and share the benefits arising from the use of genetic resources fairly and equitably." This site, a link off of the Royal Botanic Gardens, Kew main site, provides the complete CBD for Botanists. Offered in several pdf documents that are downloadable in English, French, and Spanish, the CBD for Botanists is actually a series of slides and notes -- essentially a presentation. The site notes that the presentation "is designed to be a flexible training tool, adaptable to different audiences, but can also be read for practical guidance on implementation." Included are suggestions for where to find more information, links, and further reading on the subject.

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.

[Richard Spruce, botanist-South America's explorer].  

PubMed

Between 1849 and 1864, the English botanist and explorer Richard Spruce carried out a detailed study of the Amazon flora and the costumes of the peoples who inhabited the region. To date a large part of the existing knowledge about several botanical families in the region stems from this scientist's efforts. His comprehensive interests, his detailed and precise descriptions were outstanding: nothing seems to have been left out of his scrutiny and recording aptitude. Not only was Spruce a remarkable botanist but he was also a distinctive anthropologist, linguist (he knew French, Spanish and Portuguese), geologist and geographer, as well as an acute sociological observer of the political systems and habits of the Amazonian and Andean trips in which has has been. He could thus make a considerable contribution to the understanding of indigenous beliefs and practices, as well as to the knowledge and uses of plants within the Amazonian context. Also important was his participation in the economic exploration of local species, particularly as regards the Hevea and the Cinchona genera. PMID:16680890

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.

Assesses the Seepage of Riverside Caused by Pumping  

NASA Astrophysics Data System (ADS)

This thesis mainly explored the effect of riverside water withdrawing on the seepage of a riverside. First of all, it verified the reliability of numerical model by using the ground water flow software MODFLOW to construct the four analytical models proposed by Grigoryev (1957), Hantush (1965), Wilson (1993), and Hunt (1999). This thesis explored the effect of riverside water withdrawing on the seepage of the river by means of hydrogeologic parameters and pumping well types. The findings are shown as the four analytical models are simulated by means of MODFLOW, and the verified results indicate that the riverside water withdrawing could be simulated correctly. It is indicated that whether a river fully penetrate the aquifer is an important factor that affects the seepage of a river. If a river fully penetrates the aquifer, it is estimated that the qs/Q (seepage of riverside/pumping amount) is 35.31%, while if there is a low permeable soil layer between the river and the aquifer, the qs/Q is 21.06%. It indicates that the low permeable soil layer in this model has an effect on qs/Q by 14.25%. The sensitivity analysis results of hydrogeologic parameters based on the riverside water withdrawing model indicate that the horizontal permeability coefficient, permeability coefficient of riverbed, and the difference between the ground water level and the river water level are the important factors that may affect the model, but the vertical permeability coefficient, specific storage, and specific storage coefficient do not have a remarkable effect. When the pump increases, the seepage of the river would be positively corrected to the drawdown of ground water level. The effect of pumping well diameter on qs/Q indicates that the increase of well diameter does not have a remarkable effect on the seepage of a river, but could result in drawdown of the ground water level within the well. Therefore, the drawdown of ground water could be controlled by adjusting the pumping well diameter. From the effect of the distance between the pumping well and the river, it is estimated that if the distance becomes bigger, qs/Q will decrease a little.

Zr uc(iii) and Nb uc(iv) Energy Levels and f values

Relativistic configuration-interaction (RCI) calculations have been done for the 4d^2, 5s^2 J=0 and the 4d 5p, 5s 5p J=1 levels of Zr uc(iii) and Nb uc(iv.) Except for the Nb uc(iv) 5s^2 J=0 level which we place 107 013 cm-1 above the 4d^2 ^3P J=0 level, we are in good agreement with published experimental results (J. Reader and N. Acquista, Phys. Scr. 55), 310 (1997). (E. Meinders, F. G. Meijer, and L. Remijn, Phys. Scr. 25), 527 (1982).. The Nb uc(iv) 5s^2 level is, however, in good agreement with unpublished results of Ahmad and Reader (Unpublished results of Ahmad and Reader (private communication).). For both Zr uc(iii) and Nb uc(iv) J=1, second order effects added to the 4d vf configuration are important in positioning the 5s 5p levels, whereas correlation of vp^2 is essential to energy positioning in Zr uc(iii) and Nb uc(iv) J=0. Gauge agreement for all larger (>.01) f values averages 5.6% (4.2%) for Zr uc(iii) (Nb uc(iv).) Where differences exist among the experimental Zr uc(iii) f values, we tend to favor the result of Reader and Acquista ^2.

[A little known great botanist of indochinese flora: Paul Louis Simond].  

PubMed

Alongside his brilliant scientific and administrative career, Paul Louis Simond, a famous colonial doctor, was also an observer of nature and excellent botanist. Following in the tradition begun two centuries earlier by medical doctors and pharmacists in the marine and army health services, Paul Louis Simond showed particularly interest in the family of Indichenese orchids during the third visit he made to the country in 1914-1917, while he was inspector of the health service. There remain a splendid collection of 226 watercolours depicting the different species of orchids which he had painted by a local artist on live model he was cultivating himself or had had sent to him from all over Indochina both officially and privately. Most of the plates he determined himself, accompanying them by a thorough and exact hand-written description of the floral organs allowing their identification. His knowledge in the area was worthy of a professional and he contributed largely to the botanical description of a region which is still far from being completed. Whilst the plates in the collection are of unequal scientific value (sometimes they are unfinished or without a detailed floral description, or they are copies of already existing plates), the greater part (160) constitutes a considerable original contribution to the knowledge of Indochinese orchidological flora (21 types). The entire collection was bequeathed in 1947 to the laboratoire of Phanérogamie of the Muséum National d'Histoire naturelle, where it can be consulted by scholars. PMID:11000947

Strong earthquake motion estimates for three sites on the U.C. San Diego 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, sample, 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.

Mercury exposures in riverside Amazon communities in Pará, Brazil.  

PubMed

Cross-sectional studies were conducted in three riverside communities in the state of Pará in the Amazon Region of Brazil. Two of these communities, Brasília Legal and São Luís do Tapajós, are located in a watershed exposed to mercury pollution from artisanal gold mining, and the third, Santana do Ituqui, is outside this area. The studies were based upon a community census and included all persons volunteering for participation in each community. All participants were surveyed by questionnaire for health history, occupation, residence, and diet. Clinical evaluations were also done on each subject, along with collection of blood, urine, feces, and hair. Fish samples were collected to represent the most frequently consumed species. Mercury was measured in hair and fish. Although no signs or symptoms of overt mercury intoxication were observed, persons in Brasília Legal and São Luís do Tapajós had higher levels of mercury in hair than residents of Santana de Ituqui, located out of the risk area. Levels of mercury in fish were below Brazilian health guidance limits, but the high rates of fish consumption among these populations raise concerns for the possible effects of chronic exposure, especially among young children and women of childbearing age.

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 botanist effect revisited: plant species richness, county area, and human population size in the United States.  

PubMed

The "botanist effect" is thought to be the reason for higher plant species richness in areas where botanists are disproportionately present as an artefactual consequence of a more thorough sampling. We examined whether this was the case for U.S. counties. We collated the number of species of vascular plants, human population size, and the area of U.S. counties. Controlling for spatial autocorrelation and county area, plant species richness increased with human population size and density in counties with and without universities and/or botanical gardens, with no significant differences in the relation between the two subsets. This is consistent with previous findings and further evidence of a broad-scale positive correlation between species richness and human population presence, which has important consequences for the experience of nature by inhabitants of densely populated regions. Combined with the many reports of a negative correlation between the two variables at a local scale, the positive relation between plant species richness in U.S. counties and human population presence stresses the need for the conservation of seminatural areas in urbanized ecosystems and for the containment of urban and suburban sprawl.

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.

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.

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.

A Randomized, Controlled Trial of Home Telemanagement in Patients with Ulcerative Colitis (UC HAT)  

PubMed Central

Introduction Outcomes are suboptimal in ulcerative colitis (UC). Telemedicine for UC is feasible and improves outcomes. Our goals were to evaluate a home telemanagement system for UC (UC HAT) on disease activity, quality of life (QoL), and adherence compared to best available care (BAC) in a randomized, controlled trial. Materials and Methods Adults with UC were randomly assigned to receive UC HAT or BAC for 12 months. UC HAT recruits answered questions regarding disease activity, adherence, side effects, and measured their weight weekly. An educational curriculum was delivered after each session. Alerts and action plans were generated based on the results. BAC underwent routine follow up, received written action plans and were given educational fact sheets. Seo Index scores, IBDQ scores, and adherence rates were compared between UC HAT and BAC at one year. Results 25 patients were randomized to UC HAT and 22 to BAC. After 12 months, 11 withdrew in UC HAT compared to 5 in BAC. Disease activity, QoL, and adherence were not different between groups at any time point post baseline. Adjusted analyses of trial completers using all available data, demonstrated decreased Seo index (11.9 in UC HAT (p=0.08) vs. 1.2 in BAC (p=0.84) and increased IBDQ scores (12.5 in UC HAT (p=0.04) vs. to ?3.8 in BAC (p=0.47) from baseline in UC HAT compared to BAC. Discussion UC HAT did not improve disease activity, QoL or adherence compared to BAC after 1 year. After adjustment for baseline disease knowledge, UC HAT trial completers experienced significant gains in disease-specific quality of life from baseline compared to BAC trial completers. Our results suggest a potential benefit of UC HAT. Further research is indicated to determine if telemedicine improves outcomes in patients with IBD.

The Center supports the vision of the University of California Davis (UC Davis) Health System-a healthier world through bold innovation. The CHT focuses on the four pillars of the academic health center: clinical services, research and scholarly work, education, and public service. Since 1996, the Center has provided more than 33,000 telemedicine consultation (excluding teleradiology, telepathology, and phone consultations) in over 30 clinical specialties and at more than 90 locations across California. Research and continuous evaluation have played an integral role in shaping the telehealth program, as well as strategic collaborations and partnerships. In an effort to expand the field of telehealth the CHT provides telehealth training for health professionals, technical specialists, and administrators. Furthermore, it also plays an integral role in workforce development through the education of the next generation of community primary care physicians through Rural Programs In Medical Education (Rural PRIME) and continuing educational programs for working health professionals through videoconferencing and Web-based modalities. The Center is supported through a variety of funding sources, and its sustainability comes from a mix of fee-for-service payment, contracts, grants, gifts, and institutional funding. Together with key partners, UC Davis has educated and informed initiatives resulting in legislation and policies that advance telehealth. Looking toward the future, UC Davis is focused on technology-enabled healthcare and supporting synergy among electronic health records, health information exchange, mobile health, informatics, and telehealth.

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.

LAUE lens development at UC Berkeley: status and prospects  

NASA Astrophysics Data System (ADS)

We report on the status of the Laue lens development effort led by UC Berkeley, where a dedicated X-ray beamline and a Laue lens assembly station were built. This allowed the realization of a first lens prototype in June 2012. Based on this achievement, and thanks to a new NASA APRA grant, we are moving forward to enable Laue lenses. Several parallel activities are in progress. Firstly, we are refining the method to glue quickly and accurately crystals on a lens substrate. Secondly, we are conducting a study of high-Z crystals to diffract energies up to 900 keV efficiently. And thirdly, we are exploring new concepts of Si-based lenses that could further improve the focusing capabilities, and thus the sensitivity of Laue lenses.

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

Seasonal comparisons of single-particle chemical mixing state in Riverside, CA  

NASA Astrophysics Data System (ADS)

The Study of Organic Aerosols in Riverside, CA (SOAR) field campaign, conducted in the summer and fall of 2005, focused on developing a stronger understanding of seasonal influences on the sources and processes contributing to some of the highest levels of particulate matter in the United States. On-line single-particle mass spectrometry measurements showed that carbonaceous particles generally dominated the submicron size range (>75% by number), compared to primarily aged sea salt and dust in the supermicron size range. During periods with high PM2.5 (particulate matter <2.5 ?m) mass and number concentrations, hygroscopic water-containing carbonaceous particles internally mixed with sulfate and nitrate extended up into the supermicron size mode. The mixing state of carbonaceous particles changed with season. In the summer, carbonaceous particles were primarily mixed with secondary (oxidized) organic carbon and sulfate; whereas in the fall, they were mixed mostly with ammonium nitrate. During each season, different processes contributed to the highest pollution levels. In the summer, photochemical production of highly aged secondary organic carbon resulted in daily peaks in both number and mass particle concentrations, followed by removal in the afternoon by the arrival of the clean marine air masses from the coast. In contrast, cooler, more stagnant meteorological conditions in the fall season resulted in the buildup over several days of submicron carbonaceous particles mixed with semivolatile ammonium, nitrate, and amines. In addition, Santa Ana wind events in the fall led to dust and biomass burning particles dominating both the submicron and supermicron size ranges.

Impact analysis of the UC-609 shipping package  

SciTech Connect

The inner containment vessel of the UC-609 shipping container must remain intact and sealed after undergoing a thirty foot drop onto an unyielding surface. The drop scenarios which were considered in this study included top corner down and top down drops. Results of the calculations performed for this study predict structural damage, as measured by accumulated effective plastic strains, but no failure of the inner primary containment vessel for both drop configurations. The top down impact is predicted to produce a higher-impact deceleration in the payload but the amount of damage to the primary containment vessel is predicted to be greater for the top corner impact configuration. The critical damage region for both drop scenarios is confined to the containment canister flange region. Verification of the analysis methodology was accomplished by comparing measured top corner crashes with calculated top corner crushes. Acceptable damage levels in this study were determined from calculated damage comparisons between the top corner drop, which reed intact during a top corner impact test, and the calculated top down impact damages. Comparisons were also made on the calculated maximum shear stress levels, which remained near or within NRC regulatory guidelines for both scenarios.

Microbiotas from UC patients display altered metabolism and reduced ability of LAB to colonize mucus  

PubMed Central

We compared fecal microbial communities derived either from Ulcerative Colitis (UC) patients in remission (n = 4) or in relapse (n = 4), or from healthy subjects (n = 4). These communities were used for inoculation of a dynamic in vitro gut model, which contained integrated mucin-covered microcosms. We found that the microbiota of the ‘mucus’ largely differed from that of the ‘lumen’. This was partly due to decreased mucus-associated populations of lactic acid producing bacterial populations (LAB), as LAB originating from UC patients had a significantly decreased capacity to colonize the mucin-covered microcosms as compared to those originating from healthy subjects. We found significant differences between the metabolomes of UC patients in relapse and remission, respectively, while the metabolome of patients in remission resembled that of healthy subjects. These novel findings constitute an important contribution to the understanding of the complex etiology of UC.

Personal exposure to airborne particles and metals: results from the Particle TEAM study in Riverside, California.

The PTEAM Study was the first large-scale probability-based study of personal exposure to particles. Sponsored by the U.S. Environmental Protection Agency (EPA) and the Air Resources Board of California, it was carried out by the Research Triangle Institute (RTI) and the Harvard University School of Public Health (HSPH). HSPH designed and constructed a 4-lpm, battery-operated personal monitor for inhalable particles (PM10) that could be worn comfortably for up to 14 hours by persons from 10 to 70 years old. The monitor was worn for two consecutive 12-hour periods (day and night) during the fall of 1990 by 178 participants representing 139,000 nonsmoking residents of Riverside, California. Nearly identical monitors were employed to collect concurrent indoor and outdoor samples. The monitors were equipped with a different sampling nozzle to collect fine particles (PM2.5). Population-weighted daytime personal PM10 exposures averaged 150 +/- 9 (SE) micrograms/m3, compared to concurrent indoor and outdoor concentrations of 95 +/- 6 micrograms/m3. This suggested the existence of excess mass near the person, a "personal cloud" that appeared related to personal activities. Fourteen of 15 prevalent elements also were evaluated in the personal samples. The two major indoor sources of indoor particles were smoking and cooking; even in these homes, however, more than half of the indoor particles came from outdoors, and a substantial portion of the indoor particles were of undetermined indoor origin. Outdoor concentrations near the homes were well correlated with outdoor concentrations at the central site, supporting the idea of using the central site as an indicator of of ambient concentrations over a wider area. Indoor concentrations were only weakly correlated with outdoor concentrations, however, and personal exposures were even more poorly correlated with outdoor concentrations. Elemental profiles were obtained for environmental tobacco smoke (ETS) (major contributions from potassium and chlorine) and cooking emissions (aluminum, iron, calcium, and chlorine). These profiles can be used in future source apportionment studies. PMID:8777374

Molecular dynamics simulations of UC781-cyclodextrins inclusion complexes in aqueous solution.  

PubMed

The inclusion complexes of highly potent anti-HIV agent, UC781, with ?-cyclodextrin (?CD), 2,6-dimethyl-?-cyclodextrin (M?CD), and 2-hydroxypropyl-?-cyclodextrin (HP?CD) in aqueous solution were investigated by molecular dynamics simulations. Simulations show that the phenyl ring of UC781 is trapped inside CD cavities, while the NH group of UC781 interacts with secondary hydroxyl groups at the wider rim of CDs. The different types of CDs directly affect the binding energy and the stability of the inclusion complexes. M?CD provides the most stable inclusion complex of UC781 among all CDs in this study due to the effect of methoxy groups (-OCH(3)) at C2 and C6 positions on the glucopyranose of CDs. Structure analysis of CDs and the orientation of UC781 inside CD cavities as well as the effects of aqueous solution to the inclusion complexes of UC781/CDs are discussed. Results of this study have provided an agreeable output; therefore, a reliable prediction method for other drug/CD inclusion complex formations is introduced. PMID:22922099

[Characterization of immunity status in exposed residents of the Techa riverside villages 50 years after the onset of radiation exposure].  

PubMed

The goal of the study was to assess the state of immunity in exposed residents of the Techa riverside villages 50 years, or more, after the onset of radiation exposure. 127 chronically exposed persons and 55 unexposed persons were studied. The mean dose to red bone marrow (RBM) was 0.69 Sv in exposed subjects, the mean dose to soft tissue was 0.07 Sv, the mean dose rate amounted to 0.10 Sv/yr to RBM and 0.02 Sv/yr to soft tissues in 1950. The state of the basic links of the immunity system (cellular, humoral, mononuclear phagocyte system, cytokine spectrum, etc.) was assessed using conventional methods. Exposed persons manifested a significant reduction in the absolute counts of CD3+, CD4+, CD 11b+, CD16+ lymphocytes in the peripheral blood, as well as an increase in the relative counts of CD8+. The group comprised of the Techa riverside residents demonstrated an increased immunoregulatory index (exposed individuals: 1.47; controls: 1.71, p = 0.001). An increased production of Immunoglobulin A and increased proportions of CD25+ lymphocytes were revealed in exposed individuals. Changes in the phagocytic activity of neutrophils and monocytes were insignificant, and were primarily associated with changes in the proportions of pagocytes in the peripheral blood stream. The state of the immunity in chronically exposed individuals at late time after the begin of exposure is characterized by a number of specific features reflected primarily on the cellular immunity. No relationship between immunity changes and accumulated exposure dose and dose rate were noted over the period of maximum radiation exposures (1950). PMID:18689251

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.

Kinetics studies of uc(d)-glucose hydrogenation over activated charcoal supported platinum catalyst  

NASA Astrophysics Data System (ADS)

The kinetics of the catalytic hydrogenation of uc(d)-glucose to produce uc(d)-sorbitol was studied in a three-phase laboratory scale reactor. The hydrogenation reactions were performed on activated charcoal supported platinum catalyst in the temperature range 25-65°C and in a constant pressure of 1 atm. The kinetic data were modeled by zero, first and second-order reaction equations. In the operating regimes studied, the results show that the hydrogenation reaction was of a first order with respect to uc(d)-glucose concentration. Also the activation energy of the reaction was determined, and found to be 12.33 kJ mole-1. A set of experiment was carried out to test the deactivation of the catalyst, and the results show that the deactivation is slow with the ability of using the catalyst for several times with a small decrease in product yield.

Apportionment of primary and secondary organic aerosols in southern California during the 2005 study of organic aerosols in riverside (SOAR-1).  

PubMed

Ambient sampling was conducted in Riverside, California during the 2005 Study of Organic Aerosols in Riverside to characterize the composition and sources of organic aerosol using a variety of state-of-the-art instrumentation and source apportionmenttechniques. The secondary organic aerosol (SOA) mass is estimated by elemental carbon and carbon monoxide tracer methods, water soluble organic carbon content, chemical mass balance of organic molecular markers, and positive matrix factorization of high-resolution aerosol mass spectrometer data. Estimates obtained from each ofthese methods indicate that the organic fraction in ambient aerosol is overwhelmingly secondary in nature during a period of several weeks with moderate ozone concentrations and that SOA is the single largest component of PM1 aerosol in Riverside. Average SOA/OA contributions of 70-90% were observed during midday periods, whereas minimum SOA contributions of approximately 45% were observed during peak morning traffic periods. These results are contraryto previous estimates of SOAthroughout the Los Angeles Basin which reported that, other than during severe photochemical smog episodes, SOA was lower than primary OA. Possible reasons for these differences are discussed. PMID:18983089

UC781 Microbicide Gel Retains Anti-HIV Activity in Cervicovaginal Lavage Fluids Collected following Twice-Daily Vaginal Application  

PubMed Central

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 (T15 min) and 8 to 24 h after the final application (T8-24 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 T8-24 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 log10 50% tissue culture infective dose (TCID50) 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 log10 TCID50. 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.

Temporal evolution of exposure to mercury in riverside communities in the Tapajós basin, from 1994 to 2010.  

PubMed

Our objective was to evaluate the temporal evolution of mercury exposure in two riverside communities, Barreiras and São Luiz do Tapajós, downstream of gold mining areas in the Tapajós basin, Brazilian Amazon. The quantification of mercury in hair sample was made by atomic absorption spectrophotometry in the period between 1994 and 2010. In São Luiz do Tapajós the mercury exposure varied, in log units, from the peak of 1.21 ± 0.03 ?g/g in 1996 to 1.16 ± 0.07 ?g/g in 2007. Mercury exposure in Barreiras varied, in log units, from 1.25 ± 0.04 ?g/g in 1994 to 1 ± 0.03 ?g/g in 2010, peaking in 1995 at 1.25 ± 0.06 ?g/g. Total mercury concentration found in both communities had no statistical differences across the years (p > 0.05) and they were higher than non-mercury exposed communities in Brazil and in South America. We concluded that the mercury exposure in the Tapajós basin is more than regulatory levels or higher than the general population. PMID:22527003

Yuma District Resource Management Plan, Yuma, La Paz, and Mohave Counties, Arizona and San Bernardino, Riverside and Imperial Counties, California  

SciTech Connect

Implementation of a resource management plan is proposed for 1.2 million acres within the 2.7-million-acre Yuma District, located in Yuma, La Paz, and Mohave counties, Arizona and San Bernardino, Riverside, and Imperial counties, California. Under the preferred alternative, wildlife habitat would be a priority consideration on approximately 247,740 acre, and nine special management areas would be designated. A portion of the Cactus Plain and the Chemehuevi/Needles wilderness study areas would be recommended for wilderness designation. Two areas totaling 31,360 acres would be designated as special management areas, and another six areas totaling 155,705 acres would be managed to protect their natural values. Livestock grazing would be authorized at 3998 animal unit months on four allotments. Approximately 55,490 acres of federal lands would be available for disposal and 31,220 acres would be acquired. Nine utility corridors and nine communication sites would be designated. Existing recreational facilities would be maintained, with additional facilities provided when warranted. Along Parker Strip, only floodproofed day-use facilities would be allowed within the 100-year flood plain. Off-road vehicle (ORV) use designations would be made on 640 acres and ORV use in the remainder of the district would be limited to existing roads and trails. Continuous occupancy of mobile home sites would be restricted to one five-month period in a single year. Permanent residential use would be phased out.

Dynamic UC HII regions in Sgr B2: Flickering and Ionized Flows  

NASA Astrophysics Data System (ADS)

The Sgr B2 star forming region contains a large sample of ultracompact (UC) and hypercompact (HC) HII regions. The diversity of morphologies and number of unusual broad line sources make it an ideal laboratory for testing theories of UC HII region evolution. Recent high-resolution simulations that include heating from ionizing and non-ionizing radiation show that the dense, rotating, accretion flows required to form massive stars quickly become gravitationally unstable (Peters et al. 2010a). The orbits of these dense clumps and filaments near newly born massive stars irregularly trap and expose their ionizing radiation (Peters et al. 2010b). The resulting HII region flickers between HC and UC sizes throughout the main accretion phase, rather than monotonically expanding. Peters et al. (2010b) show that this model can solve the UC HII lifetime problem (Wood & Churchwell 1989), since accretion continues ten times longer than the free expansion timescale for an HII region. Imaged at 1.3 cm, the Sgr B2 region contains 49 regions, 25 of which are hypercompact, with physical diameters < 5000 AU (Gaume et al. 1995). In the past year, we have observed this large sample of UC HII regions in the Sgr B2 region with the EVLA in the three hybrid arrays in the 1.3-cm continuum and H66? and H68? lines with a resolution of 0.25''. We have also made continuum and RRL (H53?) observations at 7 mm in the BnA configuration to obtain morphological and line information at the highest available angular resolution of 0.06'' (650 AU). These new observations of Sgr B2 will allow us to: (1) Determine the frequency and magnitude of UC HII flux and size fluctuations over a 22 year time baseline (1989 to 2011) in one of the most source-rich massive star forming regions in the Milky Way, (2) Constrain and test the theoretical models described in Peters et al. (2010a, 2010b), (3) Observe recombination lines with the improved spectral resolution and bandwidth of the new EVLA correlator, and characterize line profiles and velocity gradients, and (4) Examine the dynamics of sources with especially broad or multiply peaked line profiles discussed in De Pree et al. (2011). We present preliminary results of the new 1.3 cm continuum imaging.

Production of UC-labeled gas in BACTEC Neisseria Differentiation kits by Neisseria cinerea  

SciTech Connect

Six strains of Neisseria cinerea were tested in BACTEC Neisseria Differentiation kits (Johnston Laboratories, Inc., Towson, Md.), and all yielded positive glucose growth indices and negative maltose and fructose growth indices. These results were similar to those achieved with Neisseria gonorrhoeae. However, most of the N. cinerea isolates tested yielded 3-h glucose growth indices that were lower than those obtained with gonococci. UC-labeled gas was produced significantly faster by N. gonorrhoeae than by N. cinerea. Additional studies suggested that the UC-labeled gas produced by N. cinerea was carbon dioxide. N. cinerea strains were similar to Branhamella catarrhalis strains because both species failed to produce detectable acid from glucose, maltose, sucrose, fructose, and lactose in cysteine-tryptic agar media. However, in contrast to N. cinerea strains, B. catarrhalis strains did not metabolize glucose in BACTEC Neisseria Differentiation kits.

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.

Fine organic particle, formaldehyde, acetaldehyde concentrations under and after the influence of fire activity in the atmosphere of Riverside, California.  

PubMed

Concentrations of gas-phase organic carbons (formaldehyde (HCHO) and acetaldehyde (CH(3)CHO)) and fine particle-phase carbons (organic carbon (OC) and elemental carbon (EC)) were measured under and after the influence of fire activity in southern California. The measurement was conducted after the start of the wildfire activities from October 27 through November 6, 2003 at a site in Riverside, southern California. Under the influence of the fire activities, HCHO, CH(3)CHO and EC concentrations were found to be over two times as high as those after the fire activities ended. The total lifetime cancer risk estimated by HCHO and CH(3)CHO concentrations measured was significantly higher under the influence of the wildfire activities than that after the activities ended. OC showed a larger difference in concentrations between the two event periods as compared with gas-phase organic carbons and EC. OC/EC ratios ranged from 3.7 to 12.5 during the study period with the highest OC/EC ratio observed when the study area was under the influence of the fire activities. Correlation analysis and multiple linear regressions between OC/EC concentrations and visibility were performed. It was found that the visibility was even worse under the influence of fire activity as compared to the period after fire activity ended. EC was a stronger contributor to the visibility reduction compared to OC. The influence of air mass pathways on HCHO, CH(3)CHO, OC, and EC concentrations during the wildfire activities was addressed using a backward trajectory model developed by NOAA. PMID:18538316

Independent technical review and analysis of hydraulic modeling and hydrology under low-flow conditions of the Des Plaines River near Riverside, Illinois  

USGS Publications Warehouse

The U.S. Geological Survey (USGS) has operated a streamgage and published daily flows for the Des Plaines River at Riverside since Oct. 1, 1943. A HEC-RAS model has been developed to estimate the effect of the removal of Hofmann Dam near the gage on low-flow elevations in the reach approximately 3 miles upstream from the dam. The Village of Riverside, the Illinois Department of Natural Resources-Office of Water Resources (IDNR-OWR), and the U. S. Army Corps of Engineers-Chicago District (USACE-Chicago) are interested in verifying the performance of the HEC-RAS model for specific low-flow conditions, and obtaining an estimate of selected daily flow quantiles and other low-flow statistics for a selected period of record that best represents current hydrologic conditions. Because the USGS publishes streamflow records for the Des Plaines River system and provides unbiased analyses of flows and stream hydraulic characteristics, the USGS served as an Independent Technical Reviewer (ITR) for this study.

Development of telescope control system for the 50cm telescope of UC Observatory Santa Martina  

NASA Astrophysics Data System (ADS)

The main telescope of the UC Observatory Santa Martina is a 50cm optical telescope donated by ESO to Pontificia Universidad Catolica de Chile. During the past years the telescope has been refurbished and used as the main facility for testing and validating new instruments under construction by the center of Astro-Engineering UC. As part of this work, the need to develop a more efficient and flexible control system arises. The new distributed control system has been developed on top of Internet Communication Engine (ICE), a framework developed by Zeroc Inc. This framework features a lightweight but powerful and flexible inter-process communication infrastructure and provides binding to classic and modern programming languages, such as, C/C++, java, c#, ruby-rail, objective c, etc. The result of this work shows ICE as a real alternative for CORBA and other de-facto distribute programming framework. Classical control software architecture has been chosen and comprises an observation control system (OCS), the orchestrator of the observation, which controls the telescope control system (TCS), and detector control system (DCS). The real-time control and monitoring system is deployed and running over ARM based single board computers. Other features such as logging and configuration services have been developed as well. Inter-operation with other main astronomical control frameworks are foreseen in order achieve a smooth integration of instruments when they will be integrated in the main observatories in the north of Chile

X-ray crystal structure of the UCS domain-containing UNC-45 myosin chaperone from Drosophila melanogaster  

PubMed Central

SUMMARY UCS proteins, such as UNC-45, influence muscle contraction and other myosin-dependent motile processes. We report the first x-ray crystal structure of a UCS domain-containing protein, the UNC-45 myosin chaperone from Drosophila melanogaster (DmUNC-45). The structure reveals that the Central and UCS domains form a contiguous arrangement of seventeen consecutive helical layers that arrange themselves into five discrete armadillo repeat subdomains. Small-angle x-ray scattering data suggest that free DmUNC-45 adopts an elongated conformation and exhibits flexibility in solution. Protease sensitivity maps to a conserved loop that contacts the most carboxy-terminal UNC-45 armadillo repeat sub-domain. Amino acid conservation across diverse UCS proteins maps to one face of this carboxy-terminal sub-domain and the majority of mutations that affect myosin-dependent cellular activities lie within or around this region. Our crystallographic, biophysical, and biochemical analyses suggest that DmUNC-45 function is afforded by its flexibility and by structural integrity of its UCS domain.

Role of oral nitrate in the nitrosation of ( UC)proline by conventional microflora and germ-free rats  

SciTech Connect

The urinary excretion of N-nitroso-L-(U- UC)proline by conventional microflora and germ free rats was used to assess the role of the gut bacteria and oral nitrate in the endogenous formation of N-nitroso compounds. The formation of nitrosoproline was qualitatively similar in conventional and germfree rats suggesting no involvement of the intestinal flora in this reaction. Furthermore, nitrosamino acid production was similar following the administration of nitrate and (U- UC)proline or (U- UC)proline alone, demonstrating no involvement of exogenous nitrate under the conditions of the experiment. Dietary contamination with nitrate/nitrite was negligible. The results are consistent with the suggestion that nitrate/nitrite reserves in the body are important in the formation of nitrosoproline in vivo.

Forecasting the Maxima of Solar Cycle 24 with Coronal Fe uc(xiv) Emission  

NASA Astrophysics Data System (ADS)

The onset of the "Rush to the Poles" of polar-crown prominences and their associated coronal emission is a harbinger of solar maximum. Altrock (Solar Phys. 216, 343, 2003) showed that the "Rush" was well observed at 1.15 R o in the Fe uc(xiv) corona at the Sacramento Peak site of the National Solar Observatory prior to the maxima of Cycles 21 to 23. The data show that solar maximum in those cycles occurred when the center line of the Rush reached a critical latitude of 76?±2?. Furthermore, in the previous three cycles solar maximum occurred when the highest number of Fe uc(xiv) emission features per day (averaged over 365 days and both hemispheres) first reached latitudes 20?±1.7?. Applying the above conclusions to Cycle 24 is difficult due to the unusual nature of this cycle. Cycle 24 displays an intermittent Rush that is only well-defined in the northern hemisphere. In 2009 an initial slope of 4.6? year-1 was found in the north, compared to an average of 9.4±1.7? year-1 in the previous cycles. An early fit to the Rush would have reached 76? at 2014.6. However, in 2010 the slope increased to 7.5? year-1 (an increase did not occur in the previous three cycles). Extending that rate to 76?±2? indicates that the solar maximum in the northern hemisphere already occurred at 2011.6±0.3. In the southern hemisphere the Rush to the Poles, if it exists, is very poorly defined. A linear fit to several maxima would reach 76? in the south at 2014.2. In 1999, persistent Fe uc(xiv) coronal emission known as the "extended solar cycle" appeared near 70? in the North and began migrating towards the equator at a rate 40 % slower than the previous two solar cycles. However, in 2009 and 2010 an acceleration occurred. Currently the greatest number of emission features is at 21? in the North and 24? in the South. This indicates that solar maximum is occurring now in the North but not yet in the South.

Site Monitoring at the U.C. Observatory of Santa Martina  

NASA Astrophysics Data System (ADS)

This work presents an astroclimatologic analysis of the UC Santa Martina Observatory site. This site is located near Santiago at latitude 33.3°S, longitude 70.5°W and an altitude of 1492 meters above sea level. The analysis was performed using data of temperature, pressure, humidity, and wind collected with a Davis Net Vantage Pro 2 meteo station in a period from December 2007 to January 2011. We estimated average values for the parameters monitored on different time scales and examined daily as well as seasonal variations. We also estimated the downtime due to clouds average with an 37.23% of nights in 2010, humidity, wind over the period examined. The average relative humidity is 49%, wind is predominantly (24% of time) from southsouthwest with an average speed of 0.6 m/s. Finally, we describe Seeing measurements obtained with a DIMM monitor recently installed in the site.

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.

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.

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.

Source Apportionment of Primary and Secondary Organic Aerosols in Southern California during the 2005 Study of Organic Aerosols in Riverside (SOAR-1)  

NASA Astrophysics Data System (ADS)

Ambient sampling was conducted in Riverside, California during the 2005 Study of Organic Aerosols in Riverside (SOAR-1) to characterize the composition and sources of organic aerosol using a variety of state-of-the-art instrumentation and source apportionment techniques. The secondary organic aerosol (SOA) mass is estimated by elemental carbon and carbon monoxide tracer methods, water soluble organic carbon content, chemical mass balance of organic molecular markers, and positive matrix factorization of high-resolution aerosol mass spectrometer data. Estimates obtained from each of these methods indicate that the organic fraction in ambient aerosol is overwhelmingly secondary in nature during a period of several weeks with moderate ozone concentrations and that SOA is the single largest component of PM1 aerosol in Riverside. Average SOA/OA contributions of 70-90% were observed during mid-day periods while minimum SOA/OA contributions of 45% were observed during peak morning traffic periods. These results are contrary to previous estimates of SOA throughout the Los Angeles Basin which reported that, other than during severe photochemical smog episodes, SOA was lower than primary OA. Possible reasons for these differences include: (a) for studies that used the EC-tracer method, a large systematic underestimation of SOA can occur when primary OC/EC ratios are derived from ambient measurements during periods "dominated by POA" since there is almost always a large SOA background present (Zhang et al., ACP, 2005); and (b) for model-based studies a large underestimation of SOA is observed for this area, consistent with previous studies (e.g. Volkamer et al., GRL, 2006). The results of the PMF analysis of high-resolution AMS spectra will also be summarized, and tracers from 1-hr data from the thermal-aerosol-GCMS instrument (TAG, Williams et al., JGR 2007) are used to help the interpretation of the AMS components. PMF is applied both to ambient-only and ambient plus thermally-denuded data, the latter of which is shown to enhance the separation of AMS components and which also provides information on their volatilities. We identify six OA components. Three of these components are likely primary and are characterized by a wide range of volatilities. These include a reduced hydrocarbon-like OA (HOA) which correlates with combustion emission tracers and two minor (3% of the OA mass each) components, one of which is strongly associated with amines. The majority ( 80%) of the OA is composed of oxidized components (OOA) which are of likely secondary origin. These include a highly oxidized, low volatility regional background OOA-1 component and a less oxidized, high volatility nitrate-associated OOA-3 component, each of which have been reported from previous AMS PMF analyses. We also report for the first time the presence of a secondary OA component which is intermediate in both extent of oxidation and volatility (OOA-2). Biomass burning makes a negligible impact to OA during SOAR-1, a result that is consistent across all the apportionment methods as well as ATOFMS data.

Chemical barriers to human immunodeficiency virus type 1 (HIV-1) infection: retrovirucidal activity of UC781, a thiocarboxanilide nonnucleoside inhibitor of HIV-1 reverse transcriptase.  

PubMed Central

UC781, a thiocarboxanilide nonnucleoside inhibitor of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (RT), inhibited RT DNA polymerase activity in vitro with marked potency. Significant inhibition was noted at a 1:1 molar ratio of UC871 to RT, characteristic of a tight-binding inhibitor. Infectivity of the HIV-1(IIIB) laboratory strain was eliminated in a concentration-dependent manner following short exposure of isolated virion particles to UC781. Neither nevirapine nor certain other carboxanilide nonnucleoside inhibitors were effective in this manner. Endogenous reverse transcription in UC781-treated virus particles was markedly reduced. Treatment of chronically HIV-1-infected H9 cells with UC781 did not alter virus production, but the infectivity of the virus produced by the cells during drug exposure was markedly reduced. Moreover, the infectivity of nascent virus produced by the UC781-treated H9 cells after removal of exogenous drug was dramatically attenuated. Similarly, pretreatment of peripheral blood lymphocytes isolated from HIV-infected patients abolished the infectivity of virus produced by these cells after removal of exogenous drug, as measured by coculture experiments with uninfected cord blood mononuclear cells, indicating the utility of UC781 against a variety of clinical HIV samples. Importantly, preincubation of uninfected MT2 cells with UC781 rendered these cells refractory to subsequent HIV infection in the absence of extracellular drug, an effect that persisted for several days following removal of exogenous drug. These unique properties of UC781 indicate that this nonnucleoside inhibitor may have considerable promise for use in retrovirucidal formulations to minimize the spread of HIV from infected to noninfected individuals.

Utilization of Molasses Sugar for Lactic Acid Production by Lactobacillus delbrueckii subsp. delbrueckii Mutant Uc-3 in Batch Fermentation?  

PubMed Central

Efficient lactic acid production from cane sugar molasses by Lactobacillus delbrueckii mutant Uc-3 in batch fermentation process is demonstrated. Lactic acid fermentation using molasses was not significantly affected by yeast extract concentrations. The final lactic acid concentration increased with increases of molasses sugar concentrations up to 190 g/liter. The maximum lactic acid concentration of 166 g/liter was obtained at a molasses sugar concentration of 190 g/liter with a productivity of 4.15 g/liter/h. Such a high concentration of lactic acid with high productivity from molasses has not been reported previously, and hence mutant Uc-3 could be a potential candidate for economical production of lactic acid from molasses at a commercial scale.

Mid-IR Observation and Kinematic Model of A Cometary UC HII Region G29.96 -0.02  

NASA Astrophysics Data System (ADS)

Mid-Infrared high-resolution spectroscopy allows the possibility of the study of kinematics of Ultracompact HII (UC HII) regions inside dense molecular clouds. Using the TEXAS Echelon Cross Echelle Spectrograph (TEXES) at the IRTF, we mapped a sample of such regions in five ionic emission lines: [Ne II] (12.8?m), [Ar III] (8.99?m), [S III] (18.71?m), [S IV] (10.51?m), Hu? (12.3?m). [Ne II] observation in one comet-shaped UC HII - G29.96 -0.02 is displayed here. The comparison between our observations and model predictions shows that the stellar wind compressed bowshock is the major cause of the mass flow in the ionized region. The TEXES is the prototype of the EXES, an instrument sponsored by NASA SOFIA (the Stratospheric Observatory for Infrared Astronomy) project.

Production of Cs and Fr isotopes from a high-density UC targets with different grain dimensions  

NASA Astrophysics Data System (ADS)

A UC target material of 11.3±0.5 g/cm^3 uranium density with the grain size of 20 and 5?m manufactured in a form of pills by the method of powder metallurgy has been tested on-line within the temperature range of 1800-2100 ° C . The mass of uranium exposed to the beam was 4-7g. The yields and release rates of Cs and Fr isotopes produced by fission and spallation reactions of 238U by 1GeV protons have been measured. The yields of Cs and Fr isotopes obtained from the tested target materials have been compared, including yields of very short-lived Fr isotopes with half-lives down to 1ms. Temperature-resistant materials (porous graphite and tantalum foil) have been used for the internal-container construction, which holds the UC target pills inside a tungsten external container heated by the resistant heating. The fastest release and the highest efficiency for short-lived isotopes have been obtained for the targets with the internal container manufactured from the tantalum foil. Results of on-line tests of a big mass target (730g of 5?m grain UC target material) have been discussed.

Infrared spectra and quantum chemical calculations of the uranium-carbon molecules UC, CUC, UCH, and U(CC)2.  

PubMed

Laser evaporation of carbon rich uranium/carbon alloy targets into condensing argon or neon matrix samples gives weak infrared absorptions that increase on annealing, which can be assigned to new uranium carbon bearing species. New bands at 827.6 cm(-1) in solid argon or 871.7 cm(-1) in neon become doublets with mixed carbon 12 and 13 isotopes and exhibit the 1.0381 carbon isotopic frequency ratio for the UC diatomic molecule. Another new band at 891.4 cm(-1) in argon gives a three-band mixed isotopic spectrum with the 1.0366 carbon isotopic frequency ratio, which is characteristic of the anti-symmetric stretching vibration of a linear CUC molecule. No evidence was found for the lower energy cyclic U(CC) isomer. Other bands at 798.6 and 544.0 cm(-1) are identified as UCH, which has a uranium-carbon triple bond similar to that in UC. Evidence is found for bicyclic U(CC)(2) and tricyclic U(CC)(3). This work shows that U and C atoms react spontaneously to form the uranium carbide U?C and C?U?C molecules with uranium-carbon triple bonds. PMID:21721636

AMS measurements are expected to use half of the beam time of the accelerator. LLNL use of AMS is in research on consequences of energy usage. Examples include global warming, geophysical site characterization, radiation biology and dosimetry, and study of mutagenic and carcinogenic processes. UC research activities are in clinical applications, archaeology and anthropology, oceanography, and geophysical and geochemical research. Access is also possible for researchers outside the UC system. The technological focus of the laboratory is on achieving high rates of sample through-put, unattended operation, and advances in sample preparation methods. Because of the expected growth in the research programs and the other obligations of the present accelerator, we are designing a follow-on dedicated facility for only AMS and microprobe analysis that will contain at least two accelerators with multiple spectrometers. 10 refs., 1 fig.

Evaluation of Potential Hydrocarbon Transport at the UC-4 Emplacement Hole, Central Nevada Test Area  

SciTech Connect

Emplacement hole UC-4 was drilled in 1969 at the Central Nevada Test Area and left filled with drilling mud. Surface characterization samples collected from abandoned mud pits in the area yielded elevated concentrations of total petroleum hydrocarbon, thereby raising a concern that the mud-filled emplacement hole may be leaching hydrocarbons into alluvial aquifers. This study was initiated to address this concern. An analytical solution for flow near a wellbore was used to calculate the amount of time it would take for a contaminant to move through the mud-filled well and into the surrounding aquifer. No hydraulic data are available from the emplacement hole; therefore, ranges of hydraulic conductivity and porosity were used in 100 Monte Carlo realizations to estimate a median travel time. Laboratory experiments were performed on samples collected from the central mud pit to determine the hydrocarbon release function for the bentonite drilling mud. The median contaminant breakthrough took about 12,000 years to travel 10 m, while the initial breakthrough took about 300 years and the final breakthrough took about 33,000 years. At a distance of about 10 m away from the emplacement hole, transport velocity is dominated by the hydraulics of the aquifer and not by the emplacement hole hydraulics. It would take an additional 45,500 years for the contaminant to travel 800 m to the U.S. Department of Energy land exclusion boundary. Travel times were primarily affected by the hydraulic conductivity and porosity of the drilling mud, then by the hydraulic conductivity, porosity and hydraulic gradient of the alluvial aquifer, followed by the hydrocarbon release function.

Well-construction, water-quality, and water-level data, and pond-infiltration estimates, for three ground-water subbasins, Riverside County, California  

USGS Publications Warehouse

Reclaimed water in the Eastern Municipal Water District of Riverside County,California, is used within the service area for agricultural irrigation.Owing to the seasonal demand for reclaimed water, storage/infiltration ponds were constructed in the Winchester, Menifee, and south Perris subbasins.Reclaimed water infiltrates from these ponds and enters the groundwater system. Little is known of the effects of the reclaimed water on groundwater quality. In cooperation with the Eastern MunicipalWater District, the U.S. Geological Survey began a study in 1995 to determine the quantity and fate of reclaimed water percolating from these storage ponds. Data compiled during the first phase of this study are presented in this report. Field reconnaissance of the Winchester, Menifee, and south Perris subbasins indicated the existence of many wells. Wellconstruction data for 115 of these wells were tabulated. Available historical waterquality and waterlevel data for 178 wells in the subbasins also were tabulated. In addition, water levels in 86 wells were measured during the spring and autumn of 1995. On the basis of these data, waterlevel contour lines were drawn and the direction of groundwater flow was determined.Three lithologic sections through the subbasins were constructed from drillers' logs of 26 wells.

Aquatic life water quality criteria derived via the UC Davis method: I. Organophosphate insecticides.  

PubMed

A new methodology for deriving freshwater aquatic life water quality criteria,developed by the University of California Davis, was used to derive criteria for three organophosphate insecticides. The UC Davis methodology resulted in similar criteria to other accepted methods, and incorporated new approaches that enable criteria generation in cases where the existing USEPA guidance cannot be used.Acute and chronic water quality criteria were derived for chlorpyrifos (10 and 10 ng/L, respectively), diazinon (200 and 70 ng/L, respectively), and malathion(170 and 28 ng/L, respectively). For acute criteria derivation, Burr Type III SSDs were fitted to the chlorpyrifos and diazinon acute toxicity data sets while an alternative assessment factor procedure was used for malathion because that acute data set did not contain adequate species diversity to use a distribution.ACRs were used to calculate chronic criteria because there was a dearth of chronic data in all cases, especially for malathion, for which there was a lack of paired acute and chronic invertebrate data. Another alternate procedure enabled calculation of the malathion chronic criterion by combining a default ratio with the experimentally derived ratios. A review of the diazinon chronic criterion found it to be under protective of cladoceran species, so a more protective criterion was calculated using a lower distributional estimate. The acute and chronic data sets were assembled using a transparent and consistent system for judging the relevance and reliability of studies, and the individual study review notes are included.The resulting criteria are unique in that they were reviewed to ensure particular protection of sensitive and threatened and endangered species, and mixture toxicity is incorporated into criteria compliance for all three compounds.For chlorpyrifos and diazinon, the UCDM generated criteria similar to the long-standing USEPA (1985) method, with less taxa requirements, a more statistically robust distribution, and the incorporation of new advances in risk assessment and ecotoxicology. According to the USEPA (1985) method, the data set gathered for malathion would not be sufficient to calculate criteria because it did not contain data for a benthic crustacean. Benthic crustacean data is also required to use a distributional calculation method by the UCDM, but when data is lacking the UCDM provides an alternate calculation method." The resulting criteria are associated with higher, unquantifiable uncertainty, but they are likely more accurate than values generated using static safety factors, which are currently common in risk assessment.

Tests of high-density UC targets developed at Gatchina for neutron-rich radioactive-beam facilities  

NASA Astrophysics Data System (ADS)

Production of on-line mass-separated neutron-rich isotopes using fission induced by 1 GeV protons on high-density uranium targets (typically 11 g/cm3) has been investigated for several years at the IRIS facility. Here we review some of the achievements during the years up to 2006 and the perspectives. In particular, we present a comparison of yields in p and n-induced fission, enhancements by secondary neutrons, a comparison with lower-density targets used at PARRNe and ISOLDE for Rb and Cs isotopes and preliminary results obtained with a new UC target material.

The Dynamics of Transmission and Spatial Distribution of Malaria in Riverside Areas of Porto Velho, Rond?nia, in the Amazon Region of Brazil  

PubMed Central

The study area in Rondônia was the site of extensive malaria epidemic outbreaks in the 19th and 20th centuries related to environmental impacts, with large immigration flows. The present work analyzes the transmission dynamics of malaria in these areas to propose measures for avoiding epidemic outbreaks due to the construction of two Hydroelectric Power Plants. A population based baseline demographic census and a malaria prevalence follow up were performed in two river side localities in the suburbs of Porto Velho city and in its rural vicinity. The quantification and nature of malaria parasites in clinical patients and asymptomatic parasite carriers were performed using microscopic and Real Time PCR methodologies. Anopheles densities and their seasonal variation were done by monthly captures for defining HBR (hourly biting rate) values. Main results: (i) malaria among residents show the riverside profile, with population at risk represented by children and young adults; (ii) asymptomatic vivax and falciparum malaria parasite carriers correspond to around 15% of adults living in the area; (iii) vivax malaria relapses were responsible for 30% of clinical cases; (iv) malaria risk for the residents was evaluated as 20–25% for vivax and 5–7% for falciparum malaria; (v) anopheline densities shown outdoors HBR values 5 to 10 fold higher than indoors and reach 10.000 bites/person/year; (vi) very high incidence observed in one of the surveyed localities was explained by a micro epidemic outbreak affecting visitors and temporary residents. Temporary residents living in tents or shacks are accessible to outdoors transmission. Seasonal fishermen were the main group at risk in the study and were responsible for a 2.6 fold increase in the malaria incidence in the locality. This situation illustrates the danger of extensive epidemic outbreaks when thousands of workers and secondary immigrant population will arrive attracted by opportunities opened by the Hydroelectric Power Plants constructions.

Evaluation of pyrethrin aerial ultra-low volume applications for adult Culex tarsalis control in the desert environments of the Coachella Valley, Riverside County, California.  

PubMed

Eliminating infected female mosquitoes by aerial applications of ultra-low volume adulticides is the intervention strategy currently recommended to interrupt the epidemic transmission of encephalitis viruses, including West Nile. The current research optimized pyrethrin formulations and evaluated their efficacy in the desert environment of the Coachella Valley, Riverside County, California. After seven trials during 2004, a 1:2 by volume mixture of Pyrenone 25-5 in BVA oil optimized particle size, droplet descent to ground level, and kill of sentinel mosquitoes. Three subsequent experiments used 3 aerial applications of the 1:2 Pyrenone 25-5:BVA oil mixture on alternate nights to suppress Culex tarsalis Coquillett host-seeking abundance over a 1-square-mile target area. Mortality patterns among caged sentinel mosquitoes varied among sites and replicate sprays, indicating variable particle dispersion at ground level within the target area. In addition, mortality was observed for sentinels up to 1 mile downwind from the target area, indicating considerable particle drift. Geometric mean abundance of host-seeking Cx. tarsalis females collected at dry ice-baited traps within each of 3 sprayed and 2 unsprayed negative control strata varied similarly over time, indicating that our sprays minimally impacted the target population or that drift combined with other factors led to widespread area control. Experiments during March and June when recruitment rates were minimal showed general area-wide suppression of abundance following spray, whereas an experiment during September when recruitment rates were high from newly flooded marshes failed to prevent an area-wide increase in abundance. Clearly additional research is needed to standardize the efficacy of aerial applications of pyrethrins in hot dry desert environments. PMID:18240517

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.

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

PubMed

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. PMID:23643933

Issues and challenges of non-tenure-track research faculty: the UC Davis School of Medicine experience.  

PubMed

Nationally, medical schools are appointing growing numbers of research faculty into non-tenure-track positions, paralleling a similar trend in universities. The American Association of University Professors (AAUP) issued a statement expressing concern that the marked growth in non-tenure-track faculty can undermine educational quality, academic freedom, and collegiality. Like other medical schools, the UC Davis School of Medicine has had a rise in non-tenure-track faculty in order to enhance its research mission, in particular in the Salaried Adjunct faculty track (SalAdj). SalAdj faculty have more difficulty in achieving promotion, report inequitable treatment and less quality of life, have less opportunity to participate in governance, and feel second-class and insecure. These issues reflect those described by the AAUP. The authors describe the efforts at UC Davis to investigate and address these issues, implementation of a plan for improvement based on task force recommendations, and the lessons learned. Supporting transfer to faculty tracks in the academic senate, enhancing financial support, ensuring eligibility for internal grants, and equitable space assignments have contributed to an improved career path and more satisfaction among SalAdj faculty. Challenges in addressing these issues include limited availability of tenure-track positions, financial resources, adequate communication regarding change, and compliance with existing faculty search policies.

In vivo and in vitro effects of growth hormone on the incorporation of ( UC)leucine into protein of liver and muscle of the eel  

SciTech Connect

In vivo administration of ovine GH (2 micrograms/g body wt) increased ( UC)leucine incorporation into protein of the liver, skeletal muscle, and opercular muscle of hypophysectomized eels. Addition of ovine GH into the medium slightly increased ( UC)leucine incorporation into protein of liver slices during 5 hr in vitro incubation, but did not affect protein synthesis from ( UC)leucine in opercular muscle. In vivo pretreatment with ovine GH 48 hr prior to tissue preparation clearly increased ( UC)leucine incorporation into protein of liver slices in vitro. However, no statistically significant change was observed for in vitro incorporation of ( UC)leucine into protein of opercular muscle of hypophysectomized eels which had been previously treated with ovine GH. These results indicate that ovine GH has a protein anabolic action in the liver and muscle of the eel and that compared to mammals a rather long lag period is needed to elicit such protein anabolic actions of GH in these animals.

Metabolism of high density lipoproteins reconstituted with (TH)cholesteryl ester and ( UC)cholesterol in the rat, with special reference to the ovary  

SciTech Connect

In order to study the metabolism of high density lipoprotein (HDL)-carried sterol in the rat, human HDL was reconstituted with ( UC)cholesterol and (TH)cholesteryl ester. After iv injection into immature PMSG-human CG primed rats pretreated with 4-aminopyrazolopyrimidine and aminoglutethimide, there was time-dependent accumulation of TH and UC in various organs which reached a maximum by 15-90 min. On a milligram wet weight basis, uptake of TH and UC was greatest in the adrenals, next in ovaries, followed by the liver, with little uptake by kidneys and spleen. On an organ basis, accumulation was greatest by the liver. Coadministration of excess unlabeled HDL, but not human low density lipoprotein, reduced accumulation of radioactivity by the ovaries and adrenals by 60%, indicating a specific and saturable uptake process. Granulosa cells cultured in lipoprotein-deficient medium with reconstituted HDL formed TH- and UC-labeled 20 alpha-hydroxypregn-4-en-3-one. Over a 24-h period, utilization of both ( UC)cholesterol and (TH)cholesteryl ester was linear, but rates of utilization of the two sterol moieties were not parallel. Lysosomotropic agents had no effect on utilization of either free or esterified cholesterol for steroidogenesis but reduced degradation of SVI-labeled low density lipoprotein apoprotein. These findings lend further support to the concept of a distinct HDL pathway in steroidogenic cells of the rat.

Roman literary and epigraphic sources for the study of historical seismicity in Algeria circa 42-420 uc(ad)  

NASA Astrophysics Data System (ADS)

The seismicity of Algeria since the nineteenth century is relatively well documented. However, compared with the numerous damaging earthquakes that are documented since 1850, fewer than a dozen reports of earthquakes are listed for the pre-1850 uc(ad) period, suggesting that the historical record is missing a substantial number of earthquakes. This paper examines the use of literary and epigraphic sources relevant to the investigation of seismicity in Algeria during Roman times. We provide examples where the meager written literary record may be supplemented with appropriate archaeological and epigraphic data describing damage to ancient Roman sites. The examples show that collaboration between earth scientists and archeologists is of utility in improving the seismic record and highlights the need for further study of data sources and repositories located both inside and outside of Algeria.

Growth, spectral, optical, and dielectric studies on novel semiorganic NLO single crystal: uc(d)-phenylglycine hydrochloride  

NASA Astrophysics Data System (ADS)

Good quality novel semiorganic nonlinear optical single crystal of uc(d)-phenylglycine hydrochloride has been grown from the aqueous solution by low temperature solution growth method. X-ray diffraction reveals that the crystal crystallises into orthorhombic system with noncentrosymmetric space group P212121. Experimental parameters are evaluated based on single-crystal XRD and the calculated values of the polarisability were compared with the values of polarisability using Clausius-Mossotti equation. The functional groups present in the grown crystal were confirmed by Fourier transform infrared spectral analysis. The 1H and 13C FT-NMR has been recorded to elucidate the molecular structure. Ultraviolet-visible-near infra-red absorption studies on this crystal reveal that the minimum absorption region is around 228 nm. The optical band gap of the crystal was found to be 2.9 eV. The scanning electron microscope study has been carried out to determine the surface morphology of the grown crystal. Photoluminescence studies show that the material emits violet fluorescence. Thermal studies bring forth that the crystal is thermally stable up to 255 °C. Dielectric studies reveal that both the dielectric constant and dielectric loss decrease with the increase in frequency as like the typical semiorganic nonlinear optical crystals such as bisthiourea zinc chloride, bisthiourea cadmium chloride and uc(l)-arginine dihydrogen phosphate. Electrical conductivity measurements were carried out and the Arrhenius plot is used to determine the value of activation energy. The Kurtz powder analysis on the crystal confirms the existence of second harmonic generation properties. The SHG efficiency was found to be 1.15 times that of KDP crystal.

The onset of ferromagnetism and superconductivity in [La0.7Sr0.3MnO3(n u.c.)/YBa2Cu3O7(2 u.c.)]20 superlattices  

NASA Astrophysics Data System (ADS)

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.

UC 729-6, a human lymphoblastoid B-cell line useful for generating antibody-secreting human-human hybridomas.  

PubMed Central

UC 729-6, a 6-thioguanine-resistant human lymphoblastoid B-cell line, was fused with normal and malignant human lymphocytes. Parent UC 729-6 cells were diploid with a 21p+ marker chromosome, expressed surface and cytoplasmic IgM kappa, and doubled every 17 hr. The resulting human-human hybridomas were pseudotetraploid containing the 21p+ marker, doubled every 20-30 hr, and secreted 3-9 micrograms of human Ig per ml per 10(6) hybrid cells for greater than 9 months in continuous culture. Human Ig-secreting hybridomas were generated in 88% (14/16) of the fusions carried out and were cloned by limiting dilution (one cell per three wells) without the use of feeder layers. The mean fusion frequencies (number of wells, plated at 10(5) cells per well, showing hybrid growth per 10(6) lymphocytes fused) of UC 729-6 with normal lymphocytes ranged from 0.45 to 2.9 and with malignant B lymphocytes, from 3 to 10. Analysis of the human-human hybridomas derived from lymphocytes isolated from regional draining lymph nodes of cancer patients revealed several that secreted human monoclonal antibody that reacted by an enzyme immunoassay with some carcinoma cell lines but not with normal fibroblast cell lines. These data suggest that (i) UC 729-6 can be fused with human lymphocytes to generate stable human-human hybridomas, some of which secrete antibody reactive to human cell surface antigens, and (ii) UC 729-6 can be used to rescue Ig from nonsecretory malignant B cells and thereby allow for the production of anti-idiotype antibodies.

UNC-45/CRO1/She4p (UCS) Protein Forms Elongated Dimer and Joins Two Myosin Heads Near Their Actin Binding Region  

SciTech Connect

UNC-45/CRO1/She4p (UCS) proteins have variously been proposed to affect the folding, stability, and ATPase activity of myosins. They are the only proteins known to interact directly with the motor domain. To gain more insight into UCS function, we determined the atomic structure of the yeast UCS protein, She4p, at 2.9 {angstrom} resolution. We found that 16 helical repeats are organized into an L-shaped superhelix with an amphipathic N-terminal helix dangling off the short arm of the L-shaped molecule. In the crystal, She4p forms a 193-{angstrom}-long, zigzag-shaped dimer through three distinct and evolutionary conserved interfaces. We have identified She4p's C-terminal region as a ligand for a 27-residue-long epitope on the myosin motor domain. Remarkably, this region consists of two adjacent, but distinct, binding epitopes localized at the nucleotide-responsive cleft between the nucleotide- and actin-filament-binding sites. One epitope is situated inside the cleft, the other outside the cleft. After ATP hydrolysis and Pi ejection, the cleft narrows at its base from 20 to 12 {angstrom} thereby occluding the inside the cleft epitope, while leaving the adjacent, outside the cleft binding epitope accessible to UCS binding. Hence, one cycle of higher and lower binding affinity would accompany one ATP hydrolysis cycle and a single step in the walk on an actin filament rope. We propose that a UCS dimer links two myosins at their motor domains and thereby functions as one of the determinants for step size of myosin on actin filaments.

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.

Numerical study of the hydroclimate of the Southwestern United States using the UC-LLNL regional climate system model  

SciTech Connect

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.

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 Education and Public Outreach (E/PO) Program for RHESSI at UC Berkeley develops many resources for the formal and informal education communities as well as the general public. We have developed several inquiry-based classroom activities for middle and high school students all aligned with National Science Education Standards. These activities cover the topics of sunspots, solar flares, the solar cycle, and magnetism on the Sun, highlighting the science investigated by RHESSI. In addition, we conduct ongoing professional development workshops for educators throughout the country. These workshops cover science content as well as pedagogy and curriculum materials. For the public and the informal education communities we have developed a series of lithographs about RHESSI discoveries as well as a website containing information about RHESSI science with images and movies from RHESSI data. The E/PO team also partners with the Sun-Earth Connection Education Forum (SECEF) in it's Sun-Earth Day programs at museums, including "Eclipse 2001", "Venus Transit", and the upcoming "Ancient Observatories: Timeless Knowledge."

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

A method for preparing M13 or pUC libraries for sequencing DNA with high G + C or A + T contents.  

PubMed

A simple method is described to generate M13 or pUC libraries from DNA with a very high G + C or A + T content. The G + C-rich DNA is partially digested with HinPI or HpaII restriction enzymes and cloned into the vector linearized in its multiple cloning site with AccI. The A + T-rich DNA is partially digested with TspI and cloned into the EcoRI-linearized vector. These libraries are suitable for large-scale DNA sequencing. PMID:7489903

Formulation of fast disintegrating tablets of ternary solid dispersions consisting of TPGS 1000 and HPMC 2910 or PVPVA 64 to improve the dissolution of the anti-HIV drug UC 781.  

PubMed

Solid dispersion formulations made up of d-alpha-tocopheryl polyethylene glycol succinate 1000 (TPGS 1000) and polyvinyl pyrrolidone co-vinyl acetate 64 (PVPVA 64) or hydroxy propyl methyl cellulose 2910 (HPMC 2910) were developed in order to improve the dissolution of UC 781. UC 781 dissolution rate was markedly improved as compared to the physical mixtures and the pure drug, attaining maximum drug releases of up to 100% after only 5 min in the case of TPGS 1000-UC 781-PVPVA 64 solid dispersions and 30 min in TPGS 1000-UC 781-HPMC 2910. The increased UC 781 dissolution rate could be maintained when formulating UC 781 in PVPVA 64 tablets. The latter disintegrated in only 4 min, reaching drug releases of up to 90% (w/w). In addition, as opposed to the corresponding solid dispersions, no decrease in drug release occurred upon dissolution of PVPVA 64 tablets when the pH was increased to 6.8. Contrary to the PVPVA 64 tablet formulations, HPMC 2910 tablets showed a slow dissolution process due to the gelling nature of the polymer. The drug was slowly released as HPMC 2910 dissolved in the medium, however also in this case 90% (w/w) of the drug was dissolved after 4 h. Both polymers formed compatible blends in combination with the drug. Thermal analysis of the ternary mixtures revealed eutectic behavior exhibiting an extremely fine dispersion of the drug in the carrier. This was confirmed by the fact that no drug crystals could be detected using X-ray diffraction (XRD). As opposed to the physical mixtures, PVPVA 64 and HPMC 2910 solid dispersions did not contain any isolated polymer-rich phases, hence showed improved homogeneity. Amorphous TPGS 1000 clusters occurred in PVPVA 64 and HPMC 2910 formulations upon addition of at least 10% (w/w) UC 781, showing extremely low glass transition temperatures depending of the thermal history of the samples.

Measurement of the enthalpy and specific heat of a Be/sub 2/C-graphite-UC/sub 2/ reactor fuel material to 1980/sup 0/K  

SciTech Connect

The enthalpy and specific heat of a Be/sub 2/C-graphite-UC/sub 2/ composite nuclear fuel material were measured over the temperature range 300 to 1980/sup 0/K using differential scanning calorimetry and liquid argon vaporization calorimetry. The fuel material measured was developed at Sandia National Laboratories for use in pulsed test reactors. The material is a hot-pressed composite consisting of 40 vol % Be/sub 2/C, 49.5 vol % graphite, 3.5 vol % UC/sub 2/ and 7.0 vol % void. The specific heat was measured with the differential scanning calorimeter over the temperature range 300 to 950/sup 0/K while the enthalpy was measured over the range 1185 to 1980/sup 0/K with the liquid argon vaporization calorimeter. The normal spectral emittance at a wavelength of 6.5 x 10/sup -5/ cm was measured over the experimental temperature range. The combined experimental enthalpy data were fit using a spline routine and differentiated to give the specific heat. Comparison of the measured specific heat of the composite to the specific heat calculated by summing the contributions of the individual components indicates that the specific heat of the Be/sub 2/C component differs significantly from literature values and is approximately 0.6 cal/g-K (2.5 x 10/sup 3/ J/Kg-K) for temperatures above 1000/sup 0/K.

Coupling XRD, EXAFS, and (13)C NMR to Study the Effect of the Carbon Stoichiometry on the Local Structure of UC1±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 UC1.00. 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.

Lifetimes, branching ratios, and Landé g values for (4d+5s)^7 and (4d+5s)^6 5p states in Tc uc(i)  

NASA Astrophysics Data System (ADS)

Relativistic Configuration Interaction (RCI) calculations suggest the ^6D^e_9/2 arrow ^6F^o_11/2 transition in Tc uc(i) as a possible candidate for Atomic Trap Trace Analysis(C. Y. Chen, Y. M. Li, K.

We present lifetimes and Landé g values for J= 5/2 -- 11/2 odd parity levels and J= 3/2 -- 9/2 even parity levels with branching ratios for the most important transitions. The increasing complexity of (d+s)^n/(d+s)^n-1p (n=7 in this case) calculations provides additional computational challenges compared to our earlier calculations (e.g. n=4 in Fe uc(v(S.) M. O'Malley, D. R. Beck, and D. P. Oros, Phys. Rev. A 63), 032501 (2001).). Changes in codes and computational techniques needed to accommodate this increased complexity of our basis sets and issues of loss of accuracy (relative to earlier work) in calculated energy spectra and f value gauge agreement are also presented.

The myosin-binding UCS domain but not the Hsp90-binding TPR domain of the UNC-45 chaperone is essential for function in Caenorhabditis elegans  

PubMed Central

The UNC-45 family of molecular chaperones is expressed in metazoan organisms from Caenorhabditis elegans to humans. The UNC-45 protein is essential in C. elegans for early body-wall muscle cell development and A-band assembly. We show that the myosin-binding UCS domain of UNC-45 alone is sufficient to rescue lethal unc-45 null mutants arrested in embryonic muscle development and temperature-sensitive loss-of-function unc-45 mutants defective in worm A-band assembly. Removal of the Hsp90-binding TPR domain of UNC-45 does not affect rescue. Similar results were obtained with overexpression of the same fragments in wild-type nematodes when assayed for diminution of myosin accumulation and assembly. Titration experiments show that, on a per molecule basis, UCS has greater activity in C. elegans muscle in vivo than full-length UNC-45 protein, suggesting that UNC-45 is inhibited by either the TPR domain or its interaction with the general chaperone Hsp90. In vitro experiments with purified recombinant C. elegans Hsp90 and UNC-45 proteins show that they compete for binding to C. elegans myosin. Our in vivo genetic and in vitro biochemical experiments are consistent with a novel inhibitory role for Hsp90 with respect to UNC-45 action.

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.

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.

AbiG, a genotypically novel abortive infection mechanism encoded by plasmid pCI750 of Lactococcus lactis subsp. cremoris UC653.  

PubMed Central

AbiG is an abortive infection (Abi) mechanism encoded by the conjugative plasmid pCI750 originally isolated from Lactococcus lactis subsp. cremoris UC653. Insensitivity conferred by this Abi manifested itself as complete resistance to phi 712 (936 phage species) with only partial resistance to phi c2 (c2 species). The mechanism did not inhibit phage DNA replication. The smallest subclone of pCI750 which expressed the Abi phenotype contained a 3.5-kb insert which encoded two potential open reading frames. abiGi (750 bp) and abiGii (1,194 bp) were separated by 2 bp and appeared to share a single promoter upstream of abiGi. These open reading frames showed no significant homology to sequences of either the DNA or protein databases; however, they did exhibit the typical low G+C content (29 and 27%, respectively) characteristic of lactococcal abi genes. In fact, the G+C content of a 7.0-kb fragment incorporating the abiG locus was 30%, which may suggest horizontal gene transfer from a species of low G+C content. In this context, it is notable that remnants of IS elements were observed throughout this 7.0-kb region.

Development and characterization of a novel rat model of type 2 diabetes mellitus: the UC Davis type 2 diabetes mellitus UCD-T2DM rat.  

PubMed

The prevalence of type 2 diabetes (T2DM) is increasing, creating a need for T2DM animal models for the study of disease pathogenesis, prevention, and treatment. The purpose of this project was to develop a rat model of T2DM that more closely models the pathophysiology of T2DM in humans. The model was created by crossing obese Sprague-Dawley rats with insulin resistance resulting from polygenic adult-onset obesity with Zucker diabetic fatty-lean rats that have a defect in pancreatic beta-cell function but normal leptin signaling. We have characterized the model with respect to diabetes incidence; age of onset; longitudinal measurements of glucose, insulin, and lipids; and glucose tolerance. Longitudinal fasting glucose and insulin data demonstrated progressive hyperglycemia (with fasting and fed glucose concentrations >250 and >450 mg/dl, respectively) after onset along with hyperinsulinemia resulting from insulin resistance at onset followed by a progressive decline in circulating insulin concentrations, indicative of beta-cell decompensation. The incidence of diabetes in male and female rats was 92 and 43%, respectively, with an average age of onset of 6 mo in males and 9.5 mo in females. Results from intravenous glucose tolerance tests, pancreas immunohistochemistry, and islet insulin content further support a role for beta-cell dysfunction in the pathophysiology of T2DM in this model. Diabetic animals also exhibit glycosuria, polyuria, and hyperphagia. Thus diabetes in the UC Davis-T2DM rat is more similar to clinical T2DM in humans than in other existing rat models and provides a useful model for future studies of the pathophysiology, treatment, and prevention of T2DM.

Daniel Chambers Macreight FRCP, FLS (1799-1856), a little-known, innovative Irish botanist.  

PubMed

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."

The article revisits the work of Honório da Costa Monteiro Filho, highlighting his contribution to the study of economic botany and the taxonomy of Brazilian Malvaceae. Many of his seventy articles, are still cited. Yet little is known about his important role in educating agronomists involved with Brazilian flora and the creation of the Botanical Society of Brazil. These topics are discussed in the article, along with his work on a project to reform the teaching of agronomy in Brazil. The entire works of Monteiro Filho, archival documents, his correspondence with other scientists, and his observations on plant labels in herbaria were researched; interviews were also conducted with people with ties to him.

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.

James Edward Smith's interest in botany led him to enter medicine at Edinburgh in 1781. Smith was continuing his medical studies in London when Sir Joseph Banks (1743-1820) suggested to him that he should purchase the collection of the famous Swedish naturalist Carl Linnaeus that had just been offered to Banks. Smith bought the Linnean Collection and Library in 1784. In 1786 he was awarded the degree of Doctor of Medicine from Leiden. In 1788 Smith, with two associates, founded the Linnean Society of London and became President for life. Smith turned from medicine to natural history as a lecturer and writer. During his lifetime he produced numerous botanical works of high value, including The English Flora (1824-28), and he did much to popularize botany. PMID:19401517

It’s been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other. But how does a short piece of DNA find its match, out of the millions of "letters" in even a small genome? New work by researchers at the University of California, Davis, handling and observing single molecules of DNA, shows how it’s done. The results are published online Feb. 8 by the journal Nature.

UC Davis 94 GHz Gyrotron Traveling-wave Amplifier Development  

NASA Astrophysics Data System (ADS)

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.

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.

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.

Management of ecological reserve lands should rely on the best available science to achieve the goal of biodiversity conservation. "Adaptive Resource Management" is the current template to ensure that management decisions are reasoned and that decisions increase understanding of the system being managed. In systems with little human disturbance, certain management decisions are clear; steps to protect native species usually include the removal of invasive species. In highly modified systems, however, appropriate management steps to conserve biodiversity are not as readily evident. Managers must, more than ever, rely upon the development and testing of hypotheses to make rational management decisions. We present a case study of modern reserve management wherein beavers (Castor canadensis) were suspected of destroying habitat for endangered songbirds (least Bell's vireo, Vireo bellii pusillus, and southwestern willow flycatcher, Empidonax traillii extimus) and for promoting the invasion of an exotic plant (tamarisk, Tamarix spp.) at an artificial reservoir in southern California. This case study documents the consequences of failing to follow the process of Adaptive Resource Management. Managers made decisions that were unsupported by the scientific literature, and actions taken were likely counterproductive. The opportunity to increase knowledge of the ecosystem was lost. Uninformed management decisions, essentially "management by assertion," undermine the long-term prospects for biodiversity conservation. PMID:17318698

Water-resources data, 1970-75, for Perris Valley and vicinity, Riverside County, California  

USGS Publications Warehouse

In 1969 the U.S. Geological Survey began in Perris Valley, Calif., to determine changes in the hydrologic regime as a rural area becomes urbanized. The investigations spanned several years when precipitation was below normal in most of southern California. Surface-water records were collected for a 6-year period at 21 sites, and continuous precipitation records were obtained at four sites. Ground-water levels were tabulated from historical data at selected wells for 1941, 1968, and 1970. Water quality was monitored at several wells in the valley, and sediment data were collected at three surface-water gages. There was little increase in urbanization during the investigation.

Releases of radioactive materials from the Mayak Production Association in 1949-1956 resulted in contamination of the Techa River; a nuclide of major interest was 90Sr, which downstream residents consumed with water from the river and with milk contaminated by cow's consumption of river water and contaminated pasture. Over the years, several reconstructions of dose have been performed for the approximately 30,000 persons who make up the Extended Techa River Cohort. The purpose of the study described here was to derive a revised reference-90Sr-intake function for the members of this cohort. The revision was necessary because recently discovered data have provided a more accurate description of the time course of the releases, and more is now known about the importance of the pasture grass-cow-milk pathway for the members of this cohort. The fundamental basis for the derivation of the reference-90Sr-intake function remains the same: thousands of measurements of 90Sr content in bone with a special whole-body counter, thousands of measurement of beta-activity of front teeth with a special tooth-beta counter, and a variety of other measurements, including post mortem measurements of 90Sr in bone, measurements of 90Sr in cow's milk, and measurements of beta activity in human excreta. Results of the new analyses are that the major intake started in September 1950 and peaked somewhat later than originally postulated. However, the total intake for adult residents has not changed significantly. For children of some birth years, the intake and incorporation of 90Sr in bone tissue have changed substantially.

Elevated levels of selenium in the typical diet of Amazonian riverside populations.  

PubMed

Selenium (Se) intake is generally from food, whose Se content depends on soil Se and plant accumulation. For humans, adequate Se intake is essential for several selenoenzymes. In the Lower Tapajós region of the Brazilian Amazon, Se status is elevated with large inter-community variability. Se intake in this region, where Hg exposure is among the highest in the world, may be important to counteract mercury (Hg) toxicity. The present study was conducted in 2006 with 155 persons from four communities of the Lower Tapajós. The objectives were: i) to evaluate Se content in their typical diet and drinking water; ii) to compare food Se concentrations with respect to geographic location; and iii) to examine the contribution of consumption of different food items to blood Se. More than 400 local foods and 40 drinking water samples were collected. Participants responded to an interview-administered food frequency questionnaire and provided blood samples. Food, water and blood Se levels were assessed by ICP-MS. Since Brazil nuts may also contain significant levels of barium (Ba) and strontium (Sr), these elements were likewise analyzed in nuts. The highest Se concentrations were found in Brazil nuts, but concentrations were highly variable (median: 13.9 microg/g; range: 0.4-158.4 microg/g). Chicken, game meat, eggs and beef also contained considerable levels of Se, with median concentrations from 0.3 to 1.4 microg/g. There was no particular geographic distribution of food Se. Se concentration in drinking water was very low (< 1.4 microg/L). Blood Se covered a (103-1500 microg/L), and was positively related to regular consumption of Brazil nuts, domestic chicken and game meat. Brazil nuts were found to contain highly variable and often very high concentrations of Ba (88.0 microg/g, 1.9-1437 microg/g) and Sr (38.7 microg/g, 3.3-173 microg/g). PMID:20646739

Systematics and the origin of species from the viewpoint of a botanist: edgar anderson prepares the 1941 jesup lectures with ernst mayr.  

PubMed

The correspondence between Edgar Anderson and Ernst Mayr leading into their 1941 Jesup Lectures on "Systematics and the Origin of Species" addressed population thinking, the nature of species, the relationship of microevolution to macroevolution, and the evolutionary dynamics of plants and animals, all central issues in what came to be known as the Evolutionary Synthesis. On some points, they found ready agreement; for others they forged only a short term consensus. They brought two different working styles to this project reflecting their different appreciations of what was possible at this point in evolutionary studies. For Mayr, it was a focused project with definitive short term conclusions imminent while Anderson viewed it as an episode in an ongoing historical process that, while exciting and suggestive, remained openended. Thus, Mayr and Anderson represent two distinct perspectives on the Evolutionary Synthesis in formation; by understanding both of their points of view, we can grasp more fully the state of evolutionary theory at this key moment.

Subsequently, he lived for many years in the Caribbean, in Antigua, Jamaica, Saint Croix and Montserrat, but retired to County Mayo in 1771. Browne published The civil and natural history of Jamaica in 1756 a most significant work in terms of botanical nomenclature, which included new names for 104 genera, and he promised also a volume of medical essays, but this was never printed.

Based on photographic records, this paper reflects on the ebb and flow of the Maracujá Island dwellers, between the island and Belém, making use of the ways they use their bodies or 'know how to use' them, that Mauss called corporal techniques. Bodies disclosed, since they are always exposed and therefore capable of being visually and ethnographically categorized. Inspired on Certeau, the article seeks to think of the corporal tactics devised by island residents to practice the landscapes of belonging revealing peculiar body expressions in constructing their everyday experiences. Such observations do not refer to a body-object, but to a body that is the subject of culture, as Csordas says, a body that is "the existential basis of culture". PMID:23060203

Verification of external exposure assessment for the upper Techa riverside by luminescence measurements and Monte Carlo photon transport modeling.  

PubMed

An area located in the Southern Urals was contaminated in 1949-1956 as a result of radioactive waste releases into the Techa river by the Mayak Production Association. The external dose reconstruction of the Techa river dosimetry system (TRDS-2000) for the exposed population is based on an assessment of dose rates in air (DRA) obtained by modeling transport and deposition of radionuclides along the river for the time before 1952 and by gamma dose rate measurements since 1952. The aim of this paper is to contribute to a verification of the TRDS-2000 external dose assessment. Absorbed doses in bricks from a 130-year-old building in the heavily exposed Metlino settlement were measured by a luminescence technique. By the autumn of 1956 the population of Metlino had been evacuated, and then a water reservoir was created at the village location, which led to a change in the radioactive source geometry. Radiation transport calculations for assumed environmental sources before and since 1957 were performed with the MCNP Monte Carlo code. In combination with TRDS-2000 estimates for annual dose rates in air at the shore of the Techa river for the period 1949-1956 and contemporary dose rate in air measurements, absorbed doses in bricks were calculated. These calculations were performed deterministically with best estimates of the modeling parameters and stochastically by propagating uncertainty distributions through the calculation scheme. Assessed doses in bricks were found to be consistent with measured values within the uncertainty bounds, while their best estimates were approximately 15% lower than the luminescence measurements.

Issues in the reconstruction of environmental doses on the basis of thermoluminescence measurements in the Techa riverside  

SciTech Connect

The potential of thermoluminescence measurements of bricks from the contaminated area of the Techa river valley, Southern Urals, Russia, for reconstructing external exposures of affected population groups has been studied. Thermoluminescence dating of background samples was used to evaluate the age of old buildings available on the river banks. The anthropogenic gamma dose accrued in exposed samples is determined by subtracting the natural radiation background dose for the corresponding age from the accumulated dose measured by thermoluminescence. For a site in the upper Techa river region, where the levels of external exposures were extremely high, the depth-dose distribution in bricks and the dependence of accidental dose on the height of the sampling position were determined. For the same site, Monte carlo simulations of radiation transport were performed for different source configurations corresponding to the situation before and after the construction of a reservoir on the river and evacuation of the population in 1956. A comparison of the results provides an understanding of the features of the measured depth-dose distributions and height dependencies in terms of the source configurations and shows that bricks from the higher sampling positions are likely to have accrued a larger fraction of anthropogenic dose from the time before the construction of the reservoir. The applicability of the thermoluminescent dosimetry method to environmental dose reconstruction in the middle Techa region, where the external exposure was relatively low, was also investigated.

Water-quality trends in the Santa Ana River at MWD Crossing and below Prado Dam, Riverside County, California  

USGS Publications Warehouse

The Santa Ana River, located in an extensively urbanized basin, drains about 2,670 square miles near Los Angeles, California. Almost all flow in the river, about 200,000 acre-feet annually, is diverted to ponds where it infiltrates and recharges underlying aquifers. About 2 million people are dependent on these aquifers for water supply. In recent years, base flow in the river has increased as a result of increased discharge of treated municipal wastewater, and high flows have increased as a result of increase precipitation and urbanization. Trends in water quality were calculated for two sites?at the Metropolitan Water District (MWD) Crossing (an upstream site) and below Prado Dam (a downstream site)?using the computer program ESTREND. Water-quality data for these sites were collected by the U.S. Geological Survey from 1969 to 1995. At MWD Crossing, flow-adjusted downward trends of -1.1 microsiemens per centimeter (iS/cm) per year and -1.6 milligrams per liter (mg/L) per year were calculated for specific conductance and dissolved solids, respectively. In contrast, a flow-adjusted upward trends of 2.2 iS/cm per year for dissolved solids was calculated for the Santa Ana River below Prado Dam. Specific conductance and dissolved solids in the Santa Ana River below Prado Dam had downward unadjusted trends (not adjusted for streamflow) of -8.3 iS/cm per year and -6.0 mg/L per year, respectively. For the Santa Ana River below Prado Dam, downward unadjusted trends were calculated for ammonia (-0.04 mg/L per year) and total organic carbon (0.19 mg/L per year); flow-adjusted upward trends were calculated for nitrite plus nitrate (0.15 mg/L per year), total dissolved nitrogen (0.39 mg/L per year), and orthophosphate (0.03 mg/L per year). Statistically significant unadjusted and flow-adjusted trends were not obtained for organic nitrogen, phosphorus, and dissolved organic carbon. Data for selected trace elements and organic compounds collected between 1970-94 also are summarized in this report.

The Society for Women in the Physical Sciences: a successful mentoring program at UC Berkeley  

NASA Astrophysics Data System (ADS)

The Society for Women in the Physical Sciences (SWPS, http://socrates.berkeley.edu/ swps) at the University of California at Berkeley has been up and running successfully for three years. This organization aims to increase the number of women undergrad majors in physics, astronomy, and geology and to foster a general sense of community among all the women in these departments: faculty, postdocs, and students. The program consists of three parts: mentoring, events, and resources. The mentoring portion pairs 4 to 5 undergraduate women with one graduate mentor. These mentoring groups meet approximately weekly to visit labs, work on homework, go to science museums, or just talk and gather ideas from one another. SWPS also organizes monthly events that include all members of the department and which have in the past been social events, workshops, or discussion forums. Finally, SWPS writes and distributes, on paper and on our website, a series of guides which make “informal” information, such as where are the quiet places to study, more easily available. During this talk I will present more of the details of this program. In addition, I will present anecdotal and quantitative results of the program at Berkeley and discuss how this program has been implemented at other universities. Finally, I will discuss the general strategies behind the program and how they can be applied to other programs aimed at women in science.

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

Heracleum Sosnowskyi Manden.  

PubMed

Heracleum Sosnowskyi was discovered in 1772 and described as a separate species in 1944 by I. P. Mandenova. Its name is derived from the surname of a botanist studying Caucasian flora, Prof. D.I. Sosnowski. In the area of the Caucasus foothills, the plant reaches approximately 1-1,5 m in height, whereas in Poland its size is significantly larger, up to 3-3.5 m. Heracleum blooms from mid-June to the end of July. The flowers are arranged in umbels and last for 2-3 weeks. In Central Europe, the species colonizes mostly neglected green areas, ruins and riversides. Heracleum poses a serious threat to the human population due to its photoallergic properties, resulting from the presence of intensely toxic furanocoumarin in its sap. Furanocoumarins are found in small hairs that cover the leaves and stem, and are the components of the essential oil. They may penetrate the skin through the epithelial layer, posing a direct threat to human health. Contact with the plant, followed by sun exposure, may lead to the development of large blisters and symptoms of burns. Heracleum, in the event of consumption, is also harmful to farm animals, causing, among others, internal bleeding and diarrhea. Although the toxic properties of Heracleum have been known for many years, every summer people who had contact with the plant present at physicians of different medical specialties. PMID:22742809

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.

Superfund explanation of significant difference for the record of decision (EPA Region 9): Stringfellow Acid Pits, Riverside, CA, July 9, 1998  

SciTech Connect

This document presents the explanation of significant differences (ESD) for a proposed change to the remedy chosen to the second Record of Decision (ROD2) for the Stringfellow Superfund site (the Site''). Currently, contaminated groundwater is being extracted from a series of wells located in the original disposal area of the Site and in downgradient, contaminated zones just to the south. The extracted groundwater is pumped to the on-site Stringfellow pretreatment plant (the PTP'') where the water is treated to remove site contaminants. The treated water from the PTP is then transported by tanker truck and discharged into the regional wastewater collection system, commonly known as the Santa Ana Regional Interceptor (SARI), that serves the upper Santa Ana River watershed area. Since the time ROD2 was completed, the SARI has been extended and now passes within 1.5 miles of the Stringfellow PTP. A direct pipeline to the SARI line would eliminate the tanker truck trips on the regional highways and municipal streets, and result in a significant reduction in operating costs of the Stringfellow PTP.

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.

Conditioned taste aversion is not disrupted in rats exposed to weak, complex magnetic fields during the CS-UCS interval.  

PubMed

40 normal male Wistar rats were trained for 8 successive days to consume water ad libitum during once-daily 20-min. sessions. On the following day (training day) the rats were presented with a novel solution of 10% sucrose for 20 min. followed by a single exposure for 2 hr. to one of two weak (200 to 500 nanoTesla) complex magnetic fields or to sham-field conditions. The patterns of the two magnetic fields and the durations of their repeated presentations (interstimulus interval) were designed to be resonant with the intrinsic firing of hippocampal pyramidal and solitary neurons, respectively. Immediately after the applications of the fields one-half the number of rats were injected with lithium to evoke gastrointestinal malaise. Although on the test day, three days later, rats previously injected with the lithium exhibited the usual robust reduction in the consumption of sucrose compared to the training day, there were no statistically significant differences between field-exposed and sham-field groups for these ratios. We conclude that a 2-hr. exposure to weak magnetic fields designed to simulate the pattern of two structures likely involved with conditioned taste aversion between the conditioned stimulus and the unconditioned stimulus did not affect this behavior.

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.

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. To focus attention on areas of topical interest i

Construction of improved Escherichia-Pseudomonas shuttle vectors derived from pUC18/19 and sequence of the region required for their replication in Pseudomonas aeruginosa.  

PubMed

The nucleotide sequence of the 1.9-kb PstI fragment from pRO1614, that allows stable maintenance of pMB1 (ColE1)-based cloning vectors in Pseudomonas, was determined. This fragment encodes a putative origin of replication (ori), a replication-controlling protein, and the C terminus of the Tn3 beta-lactamase-encoding gene. Improved versions of the broad-host-range plasmid vectors, pUCP18 and pUCP19, were constructed by deletion of nonessential DNA or replacement of nonessential DNA with an antibiotic-resistance cassette.

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.

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.

Long wave infrared (8 to 14 microns) hyperspectral imager based on an uncooled thermal camera and the traditional CI block interferometer (SI-LWIR-UC)  

NASA Astrophysics Data System (ADS)

Since the early '90's CI has been involved in the development of FTIR hyperspectral imagers based on a Sagnac or similar type of interferometer. CI also pioneered the commercialization of such hyperspectral imagers in those years. After having developed a visible version based on a CCD in the early '90's (taken on by a spin-off company for biomedical applications) and a 3 to 5 micron infrared version based on a cooled InSb camera in 2008, it is now developing an LWIR version based on an uncooled camera for the 8 to 14 microns range. In this paper we will present design features and expected performance of the system. The instrument is designed to be rugged for field use, yield a relatively high spectral resolution of 8 cm-1, an IFOV of 0.5 mrad., a 640x480 pixel spectral cube in less than a minute and a noise equivalent spectral radiance of 40 nW/cm2/sr/cm-1 at 10?. The actually measured performance will be presented in a future paper.

Oxygenated VOCs as indicators of regional-scale photochemistry: comparison of CMAQ model results with measurements from the UC Blodgett Forest Station, California  

NASA Astrophysics Data System (ADS)

We present a study of a subset of the processes which influence ozone (O3) and Secondary Organic Aerosol (SOA) on a regional scale. Using measurements taken at Blodgett Forest Research Station (BFRS) during the BEARPEX 2007 & 2009 campaigns, we examine the role of photochemistry within the canopy and the influences of anthropogenic emissions (ex. NOx) in a region dominated by biogenic Volatile Organic Compound (VOC) emissions. Measurements of formaldehyde (HCHO) and glyoxal (GL) are used as tracers for the generalized oxidation of VOC at BFRS. We investigate observed gradients in GL and HCHO with respect to rapid photochemistry within the canopy. The interaction of anthropogenic emissions (in this case the aged anthropogenic effluent from the Sacramento area) with biogenic emissions is examined. The Community Multiscale Air Quality (CMAQ) model is used both for direct comparison to measurement and as a means to generalize the processes under study here to Northern California as a region. Finally, we employ ratios of compounds (ex. GL / HCHO, GL / MPAN, etc.) in both measurement and CMAQ to study plume evolution and the antecedent conditions of airmasses arriving at BFRS. These reduced-complexity datasets attenuate the influence of meteorology, allowing more complete analysis of measured data and enabling comparison to measurements from other campaigns or platforms and with models.

Changes in droplet surface tension affect the observed hygroscopicity of photochemically aged biomass burning aerosol.  

PubMed

This study examines the hygroscopic and surface tension properties as a function of photochemical aging of the aerosol emissions from biomass burning. Experiments were conducted in a chamber setting at the UC-Riverside Center for Environmental Research and Technology (CE-CERT) Atmospheric Processes Lab using two biomass fuel sources, manzanita and chamise. Cloud condensation nuclei (CCN) measurements and off-line filter sample analysis were conducted. The water-soluble organic carbon content and surface tension of the extracted filter samples were measured. Surface tension information was then examined with Köhler theory analysis to calculate the hygroscopicity parameter, ?. Laboratory measurement of biomass burning smoke from two chaparral fuels is shown to depress the surface tension of water by 30% or more at organic matter concentrations relevant at droplet activation. Accounting for surface tension depression can lower the calculated ? by a factor of 2. This work provides evidence for surface tension depression in an important aerosol system and may provide closure for differing sub- and supersaturated ? measurements. PMID:23957441

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 found to be 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 NO3 has been investigated. Very little aerosol formation is observed in the presence of O3 only. However, after addition of NO, and by extension NO3, large yields of aerosol mass loadings (~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 (<17% 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 and lead to elevated nighttime PM loadings, when significant levels on NO3 exist.

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.

Analyse frühgeschichtlicher Gefäßinhalte  

NASA Astrophysics Data System (ADS)

Informations on the contents of prehistoric vessels were up to now obtained by occasional findings of residues recognizable by botanists. Recently the application of a method of food analysis, the fat determination, considerably broadened the possibilities, for from almost every potsherd fat can be extracted. Difficulties arise by the decomposition of old fats, which can be overcome by simulations in the laboratory or by extraction of fat from old findings which are determined by the botanist or zoologist.

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'>

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.

Retrospective searching for poisonous plant vouchers.  

PubMed

Few published reports of plant poisoning, whether experimental or accidental, document vouchers. This can be rectified by retrospective location of vouchers through determination of a collaborating botanist or herbarium of deposit. An absolute voucher is referenced in the toxicology report. For a probable voucher the report does not identify an herbarium specimen, but the report and the specimen label or sheet agree on plant name, collector's name, collection date and place. A possible voucher is perhaps from the exposure lot, but was collected by the collaborating botanist at a somewhat earlier or later date than the exposure date. On the other hand, a supporting specimen was collected by the collaborating botanist but is not from the exposure lot. Vouchers and supporting specimens for some species of Asclepias tested for toxicity by CD Marsh and coworkers were found in the US National Herbarium at the Smithsonian Institution, Washington DC.

Influence of environmental parameters on secondary organic aerosol formation  

NASA Astrophysics Data System (ADS)

The influence of environmental parameters on secondary organic aerosol (SOA) was extensively investigated in the UC Riverside/CE-CERT environmental chamber. The presence of water vapor provided an additional SOA formation pathway during cyclohexene ozonolysis that increased SOA formation by ˜30%. The presence of dissolved salts had minimal impact as compared to the presence of water vapor. Temperature proved to be an important SOA formation parameter; aerosol formation increased by 3.5 times at 278K as compared to 300K for both alpha-pinene and cyclohexene isothermal ozonolysis. Changing experimental temperatures, in most cases led to a different gas-particle equilibrium, even after returning to the original temperature set point. A model, temperature influenced partitioning aerosol yield (TIPAY), was created to explain these results by incorporating a thermally labile component, a traditional gas to particle partitioning component, and an additional gas to particle partitioning component whose formation potential was temperature independent. Increasing light intensity, measured as the photolysis rate of NO2 to NO (k1), was found to increase SOA formation for the m-xylene/NOx photooxidation system. Irradiation source had a slight effect on total SOA formation as an irradiation spectrum more similar to natural light produced slightly more SOA than that with black lights, provides the wavelengths necessary for NO2 photolysis, at the same light intensity. Modeling of the gas phase chemistry with SAPRC07, supports the idea that the concentration of radical species OH and HO 2 greatly determine the amount of SOA formation. Building on SAPRC07, the SOA formation model PM-SAPRC08, was developed to determine the dominate gas phase reactions needed to predict SOA formation results for 100 experiments. While 7 simulations are tested, several of which are published routes, none adequately predicted SOA formation. Results of the influence of these environmental parameters provide a wealth of experimental data, along with model simulations that provide insight to SOA formation behavior and SOA formation mechanisms; essential to bridging the apparent disconnect between models of SOA production based on environmental chambers and that estimated from direct ambient measurements.

Secondary succession: insect-plant relationships  

SciTech Connect

Botanists have dominated the study of secondary succession, and as a result, models and theories have focused on plants. Recent work, however, has revealed several complex relationships between plants and insects during succession, including adaptations of life-cycle strategies. Furthermore, insect herbivores play a key role in the course and rate of plant succession.

Biology, like all sciences, is increasingly compartmentalized. This helps us to interact more easily with fellow specialists, but also tends to shield us from useful cross-fertilization with other fields. For example, plant and animal ecologists have established largely distinct research traditions over the years. Botanists studying population ecology, interspecific competition, and ecological and evolutionary aspects of sexual reproduction can benefit
