    1973-01-01

    A plan was developed during 1971 to determine gross tectonic plate motions along the San Andreas Fault System in California. Knowledge of the gross motion along the total fault system is an essential component in the construction of realistic deformation models of fault regions. Such mathematical models will be used in the future for studies which will eventually lead to prediction of major earthquakes. The main purpose of the experiment described is the determination of the relative velocity of the North American and the Pacific Plates. This motion being so extremely small, cannot be measured directly but can be deduced from distance measurements between points on opposite sites of the plate boundary taken over a number of years.

  5. Mesure et retroaction sur un qubit multi-niveaux en electrodynamique quantique en circuit non lineair

    Science.gov (United States)

    Boissonneault, Maxime

    L'electrodynamique quantique en circuit est une architecture prometteuse pour le calcul quantique ainsi que pour etudier l'optique quantique. Dans cette architecture, on couple un ou plusieurs qubits supraconducteurs jouant le role d'atomes a un ou plusieurs resonateurs jouant le role de cavites optiques. Dans cette these, j'etudie l'interaction entre un seul qubit supraconducteur et un seul resonateur, en permettant cependant au qubit d'avoir plus de deux niveaux et au resonateur d'avoir une non-linearite Kerr. Je m'interesse particulierement a la lecture de l'etat du qubit et a son amelioration, a la retroaction du processus de mesure sur le qubit de meme qu'a l'etude des proprietes quantiques du resonateur a l'aide du qubit. J'utilise pour ce faire un modele analytique reduit que je developpe a partir de la description complete du systeme en utilisant principalement des transfprmations unitaires et une elimination adiabatique. J'utilise aussi une librairie de calcul numerique maison permettant de simuler efficacement l'evolution du systeme complet. Je compare les predictions du modele analytique reduit et les resultats de simulations numeriques a des resultats experimentaux obtenus par l'equipe de quantronique du CEASaclay. Ces resultats sont ceux d'une spectroscopie d'un qubit supraconducteur couple a un resonateur non lineaire excite. Dans un regime de faible puissance de spectroscopie le modele reduit predit correctement la position et la largeur de la raie. La position de la raie subit les decalages de Lamb et de Stark, et sa largeur est dominee par un dephasage induit par le processus de mesure. Je montre que, pour les parametres typiques de l'electrodynamique quantique en circuit, un accord quantitatif requiert un modele en reponse non lineaire du champ intra-resonateur, tel que celui developpe. Dans un regime de forte puissance de spectroscopie, des bandes laterales apparaissent et sont causees par les fluctuations quantiques du champ electromagnetique intra-resonateur autour de sa valeur d'equilibre. Ces fluctuations sont causees par la compression du champ electromagnetique due a la non-linearite du resonateur, et l'observation de leur effet via la spectroscopie d'un qubit constitue une premiere. Suite aux succes quantitatifs du modele reduit, je montre que deux regimes de parametres ameliorent marginalement la mesure dispersive d'un qubit avec un resonateur lineaire, et significativement une mesure par bifurcation avec un resonateur non lineaire. J'explique le fonctionnement d'une mesure de qubit dans un resonateur lineaire developpee par une equipe experimentale de l'Universite de Yale. Cette mesure, qui utilise les non-linearites induites par le qubit, a une haute fidelite, mais utilise une tres haute puissance et est destructrice. Dans tous ces cas, la structure multi-niveaux du qubit s'avere cruciale pour la mesure. En suggerant des facons d'ameliorer la mesure de qubits supraconducteurs, et en decrivant quantitativement la physique d'un systeme a plusieurs niveaux couple a un resonateur non lineaire excite, les resultats presentes dans cette these sont pertinents autant pour l'utilisation de l'architecture d'electrodynamique quantique en circuit pour l'informatique quantique que pour l'optique quantique. Mots-cles: electrodynamique quantique en circuit, informatique quantique, mesure, qubit supraconducteur, transmon, non-linearite Kerr

  8. Quantitative analysis and relevant features of the scientific literature related to SAXS and SANS

    International Nuclear Information System (INIS)

    We present and discuss here numerical information derived from a systematic searching of scientific papers related to SAXS and SANS published in indexed journals - from 1945 until nowadays - recorded by the Web of Science Data Bank (WoS). We have detected interesting features regarding the time dependence of the number of papers/year, N(t), indicating the existence of three well-defined periods of historical evolution with rather well-defined boundaries. All three periods exhibit a positive and approximately linear variation of N(t) but, at the two transitions between periods, the rate of growth exhibits clear and strong increases. Differences of the historical evolutions in the numbers of papers/year related to SAXS and to SANS were established. The different behaviours regarding the numbers of papers/year related to SAXS and to SANS and the existence of three different and well defined periods for N(t) can be qualitatively understood as a consequence of the progressive and increasing availability along the last three decades of very brilliant synchrotrons, last generation commercial X-ray sources, new neutron facilities, powerful computers and novel theoretical approaches for SAS data analysis. The rates of growth in the number of papers/year published by authors from a set of different countries are approximately constant along the last two decades. For other countries we have detected a slowing down effect in the number of papers/year while a clear acceleration could be noticed for the production of SAS papers by authors from several emerging countries. These opposite trends compensate in such a way that the number of SAS (SAXS+SAXS) articles published per year all around the world maintained a vigorous linear growth - during more than 20 years - at a constant rate of 60 papers/year, without any indication of eventual saturation. The observed distribution of articles among different journals indicates that a very high fraction of the volume of SAS research is focused to the structure of soft matter.

    A study is made of the absolute stability of nonlinear systems, using Liapounov's second method and taking into account the results obtained from V.M. Popov's work. The results already established are first presented, in particular concerning the frequency domain criterions for absolute stability of automatic control systems containing one single non linearity. The results have been extended to show the existence of a limiting parabola. New use is then made of the methods studied for deriving absolute stability criterions for a system containing a different type of non linearity. Finally, the results obtained are considered from the point of view of Aizerman's conjecture. (author) [French] Dans ce travail, on etudie la stabilite absolue des systemes non lineaires utilisant la deuxieme methode de Liapounov en tenant compte des resultats acquis a partir des travaux de V.M.

On a prolonge ces resultats jusqu'a l'etablissement de l'existence d'une parabole limite. On fait ensuite une nouvelle utilisation des methodes etudiees, etablissant des criteres de stabilite absolue pour un systeme comportant un type different de non linearite.

  13. Anomalous Diffuse CO2 Emission Changes at San Vicente Volcano Related to Earthquakes in El Salvador, Central America

    San Vicente or Chichontepeque (2,180 m a.s.l.) is a composite andesitic volcano located 50 Km east of San Salvador. Its paired edifice rises from the so-called Central Graben, an extensional structure parallel to the Pacific coast, and has been inactive for the last 3000 yrs. Fumaroles (98.2°C ) and hot spring waters are present along radial faults at two localities on the northern slope of the volcano (Aguas Agrias and El Infiernillo). CO2 is the most abundant component in the dry gas (>90%) and its mean isotopic composition (? 13C(CO2)=-2.11 ‰ and 3He/4He of 6.9 Ra) suggests a magmatic origin for the CO2. These manifestations are supposed to be linked to a 1,200 m depth 250°C reservoir with a CO2 partial pressure of 14 bar extended beneath the volcano (Aiuppa et al., 1997). In February 13, 2001, a 6.6 magnitude earthquake with epicenter about 20 Km W of San Vicente damaged and destroyed many towns and villages in the north area of the volcano causing some deceases. In addition, two seismic swarms were recorded beneath the northeastern flank of the volcano in April and May 2001. Searching for any link between the actual seismic activity and changes in the diffuse CO2 degassing at San Vicente, an NDIR instrument for continuos monitoring of the diffuse CO2 degassing was set up at Aguas Agrias in March 2001. Soil CO2 efflux and several meteorological and soil physical variables were measured in an hourly basis. Very significative pre-seismic and post-seismic relationships have been found in the observed diffuse CO2 efflux temporal variations related to the May 2001 seismic swarms. A sustained 50% increase on the average diffuse CO2 efflux was observed 8 days before the May 8, 5.1 magnitude earthquake. This pre-seismic behaviour may be considered a precursor of the May 2001 seismic swarm at San Vicente volcano. However, about a three-fold increase in the diffuse CO2 efflux was also observed after the intense seismicity recorded on May 8-9. These preliminary results suggest that changes in the fluid pore-pressure within faults/fractures associated to the volcanic roots may be triggering, enhancing and responding (aperture and closure of fractures) to the local seismicity in the area of San Vicente volcano.

    Cette recherche s'inscrit dans le cadre du projet de recherche Active Control Technology entre l'Ecole de Technologie Superieure et le constructeur Bombardier Aeronautique . Le but est de concevoir des strategies de commandes multivariables et robustes pour des modeles dynamiques d'avions. Ces strategies de commandes devraient assurer a l'avion une haute performance et satisfaire des qualites de vol desirees en l'occurrence, une bonne manoeuvrabilite, de bonnes marges de stabilite et un amortissement des mouvements phugoides et rapides de l'avion. Dans un premier temps, nous nous sommes principalement interesses aux methodes de synthese LTI et plus exactement a l'approche Hinfinity et la mu-synthese. Par la suite, nous avons accorde un interet particulier aux techniques de commande LPV. Pour mener a bien ce travail, nous avons envisage une approche frequentielle, typiquement Hinfinity. Cette approche est particulierement interessante, dans la mesure ou le modele de synthese est construit directement a partir des differentes specifications du cahier des charges. En effet, ces specifications sont traduites sous forme de gabarits frequentiels, correspondant a des ponderations en entree et en sortie que l'on retrouve dans la synthese Hinfinity classique. Par ailleurs, nous avons utilise une representation de type lineaire fractionnelle (LFT), jugee mieux adaptee pour la prise en compte des differents types d'incertitudes, qui peuvent intervenir sur le systeme. De plus, cette representation s'avere tres appropriee pour l'analyse de la robustesse via les outils de la mu-analyse. D'autre part, afin d'optimiser le compromis entre les specifications de robustesse et de performance, nous avons opte pour une structure de commande a 2 degres de liberte avec modele de reference. Enfin, ces techniques sont illustrees sur des applications realistes, demontrant ainsi la pertinence et l'applicabilite de chacune d'elle. Mots cles.

  16. Problems related to water quality and algal control in Lopez Reservoir, San Luis Obispo County, California

    1975-01-01

    A study to determine the present enrichment status of Liopez Reservoir in San Luis Obispo county, California, and to evaluate copper sulfate algal treatment found that stratification in the reservoir regulates nutrient release and that algal control has been ineffective. Nuisance algal blooms, particularly from March to June, have been a problem in the warm multipurpose reservoir since it was initially filled following intense storms in 1968-69. The cyanophyte Anabaena unispora has been dominant; cospecies are the diatoms Stephanodiscus astraea and Cyclotella operculata, and the chlorophytes Pediastrum deplex and Sphaerocystis schroeteri. During an A. unispora bloom in May 1972 the total lake surface cell count was nearly 100,000 cells/ml. Thermal stratification from late spring through autumn results in oxygen deficiency in the hypolimnion and metalimnion caused by bacterial oxidation of organic detritus. The anaerobic conditions favor chemical reduction of organic matter, which constitute 10-14% of the sediment. As algae die, sink to the bottom, and decompose, nutrients are released to the hypolimnion , and with the autumn overturn are spread to the epilimnion. Algal blooms not only hamper recreation, but through depletion of dissolved oxygen in the epilimnion may have caused periodic fishkills. Copper sulfate mixed with sodium citrate and applied at 1.10-1.73 lbs/acre has not significantly reduced algal growth; a method for determining correct dosage is presented. (Lynch-Wisconsin)

    In nuclear resonance fluorescence as in the optical field abnormal dispersion curves are related to the absorption lines. It is possible, by using quadrupolar or magnetic splitting of the line in the case of recoilless resonance fluorescence (Moessbauer effect) to obtain differential dispersion effects between the two orthogonal linear or the two inverse circular components of the incident gamma radiation. These effects induce bi-refraction phenomena or Faraday rotation on the gamma beam, which have been studied on Fe-57 enriched absorbers. (author) [French] Comme dans le domaine optique, aux raies d'absorption de fluorescence resonnante des noyaux atomiques sont associees des courbes de dispersion anormale. Les decompositions des raies d'absorption de fluorescence resonnante sans recul (raies Moessbauer) par couplage quadrupolaire ou effet Zeeman permettent d'obtenir des effets dispersifs differentiels entre composantes lineaires orthogonales ou circulaires inverses du rayonnement gamma incident. Ces effets se traduisent par des phenomenes de birefringence ou de rotation Faraday, qui ont pu etre etudies sur des milieux enrichis en fer-57. (auteur)

  2. Distribution of nitrate and related nitrogen species in the unsaturated zone, Redlands and vicinity, San Bernardino County, California

    Science.gov (United States)

    Klein, John M.; Bradford, Wesley L.

    1979-01-01

    Nitrogen in the unsaturated soil zone in the vicinity of Redlands in San Bernardino County, Calif., has been suspected as the source of nitrate in water from wells. Plans have been made to recharge the aquifer with imported surface water. If this occurs, the rising water table will intercept soluble nitrate in the unsaturated zone. This study was made to quantify and delineate the distribution of the nitrate in the unsaturated zone. Thirteen test holes were drilled in areas of various land uses, and samples of the unsaturated-zone materials were obtained with depth. In 10 of the test holes, the maximum nitrate-nitrogen (N03--N) concentrations occurred within 10 feet of land surface suggesting N03--N sources at the surface. Ranking the test holes according to near-surface N03--N concentrations showed that, of the top six, only two are in irrigated citrus areas. One is in an abandoned feedlot. Of the lowest six, four are in irrigated citrus areas and one is in the Santa Ana River channel. The control test hole ranked fourth suggesting that relatively high N03--N concentrations can occur in near-surface soils even in the absence of human habitation. Analysis according to one conceptual model suggests that raising the water-table altitude by aquifer recharge will intercept N03--N now in the unsaturated zone causing increases in N03--N concentrations in water from wells of up to 48 milligrams per liter. The largest increases will occur in the vicinity of irrigated citrus areas. (Woodard-USGS).

  5. Prediction des vibrations eoliennes d'un systeme conducteur-amortisseur avec une methode temporelle non lineaire

    Langlois, Sebastien

    Les vibrations eoliennes sont la cause principale de bris de conducteurs en fatigue des lignes aeriennes de transport d'energie electrique. Ces vibrations sont dues a des detachements tourbillonnaires produits dans le sillage du conducteur. Une methode commune de reduction des vibrations est l'ajout d'amortisseurs de vibrations pres des pinces de suspension. Contrairement aux essais en ligne experimentale, la modelisation numerique permet d'evaluer rapidement et a faible cout la performance d'un amortisseur de vibration sur une portee de ligne aerienne. La technologie la plus frequemment utilisee fait appel au principe de balance d'energie (PBE) en evaluant le niveau de vibrations pour lequel la puissance injectee par le vent est egale a la puissance dissipee par le conducteur et l'amortisseur. Les methodes actuelles pour la prediction des vibrations reposent sur des hypotheses simplificatrices quant a la modelisation de l'interaction conducteur-amortisseur. Une approche prometteuse pour la prediction des vibrations est l'utilisation d'un modele numerique temporel non lineaire qui permet de mieux representer la masse, la geometrie, la rigidite et l'amortissement du systeme. L'objectif principal de ce projet de recherche est de developper un modele numerique avec integration temporelle directe d'un conducteur et d'un amortisseur en vibration permettant de reproduire le comportement dynamique du systeme pour la gamme de frequence et d'amplitude typique des vibrations eoliennes des conducteurs. Un modele par elements finis d'un conducteur seul en vibration resolu par integration temporelle directe a d'abord ete developpe en considerant une rigidite de flexion variable. Comme une rigidite de flexion constante et egale a 50% de la rigidite de flexion maximale theorique ( EImax) est jugee adequate pour la modelisation du conducteur, c'est cette valeur qui a ete utilisee pour la suite du projet. Ensuite, des modeles non-lineaires pour deux types d'amortisseur de vibrations (Stockbridge et Hydro-Quebec) ont ete developpes. Ces modeles reproduisent adequatement le comportement dynamique des amortisseurs pour une grande gamme de frequences et d'amplitudes de deplacement. Finalement, les modeles d'amortisseur ont ete integres au modele de conducteur et uil nouvel outil de prediction de vibrations eoliennes base sur le principe de balance d'energie (PBE) a ete developpe. Celui-ci permet de bien reproduire des amplitudes de vibration mesurees sur une ligne experimentale, en particulier dans la gamme 8 a 35 Hz. A plus long terme, un tel modele pourrait servir de point de depart vers une modelisation temporelle complete du phenomene de vibrations eoliennes des conducteurs incluant l'excitation eolienne, l'auto-amortissement des conducteurs et des conditions limites realistes pour les lignes aeriennes. Mots-cles : dynamique de cable, elements finis, conducteurs, amortisseurs, vibrations eoliennes, lignes aeriennes electriques

    1985-02-01

    San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to collectors around the world and from payment of an annual budget subsidy by the Italian government. Despite its close ties with Italy, San Marino has maintained its distinctive status for centuries. PMID:12178101

  8. On-going development on MINT's small angle neutron scattering (SANS) facility upgrading and related research activities

    International Nuclear Information System (INIS)

    The TRIGA MARK II Research reactor at the Malaysian Institute for Nuclear Research (MINT) was commissioned in July 1982: next year will be its 20 year criticality. Since then various works have been performed to utilize the neutrons produced from this steady state reactor. Projects undertaken are the development and utilization of the Neutron Radiography (MyNR) and Small Angle Neutron Scattering (MySANS) facilities. Materials research, together with traditional scientific interest in understanding matter at the atomic scale, requires detail knowledge of the arrangement and the dynamics of the atoms or molecules. To enhance Malaysian research and development in this area in particular nanoparticle and nanostructure, MINT has made a dedicated commitment to strengthen the utilizing and maintaining the existing small angle neutron scattering facility to its optimal. This paper describes the recent progress of the MySANS facility and its proposed applications in materials science and technology research and education. Both management and technical strategies are generally explained. In addition a future work plan is also noted. (author)

    2005-01-01

    Full Text Available Empirical relationships to estimate vertical attenuation coefficient of photosynthetically available radiation (KPAR using Secchi disk, vertical black disk, and horizontal sighting ranges for San Quintín Bay, Baja California, were developed. Radiometric PAR profiles were used to calculate KPAR. Vertical (ZD and horizontal (HS sighting ranges were measured with white (Secchi depth or ZSD, HSW and black (ZBD, HSB targets. The empirical power models KPAR = 1.48 ZSD –1.16, KPAR = 0.87 ZBD –1.52, KPAR = 0.54 HSW –0.65 and KPAR = 0.53 HSB –0.92 were developed for the corresponding relationships. The parameters of these models are not significantly different from those of models developed for Punta Banda Estuary, another Baja California lagoon, with the exception of the one for the KPAR-HSW relationship. Also, parameters of the KPAR-ZSD model for San Quintín Bay and Punta Banda Estuary are not significantly different from those developed for coastal waters near Santa Barbara, California. A set of general models is proposed that may apply to coastal water bodies of northwestern Baja California and southern California (KPAR = 1.45 ZSD –1.10, KPAR = 0.92 ZBD –1.45, and KPAR = 0.70 HSB –1.10. While this approach may be universal, more data are needed to explore the variability of the parameters between different water bodies.

    Tributyltin and its degradation products, mono-and dibutyltin have been determined in sediments collected in some representative sites in San Vicente Bay, Chile. The organic matter contents of sediments and water collected simultaneously from the same sampling sites were also determined. High levels of total organic carbon were found in sediments, especially in those from the northern part of the bay (1.80-8.87%). Good correlations were found between total organic carbon and the oxidizable and refractory carbon fractions. Among the butyltin species determined, TBT presented the highest levels, ranging from 14 to 1,560 ng Sn g(-1) dry weight. Concentration ratios of TBT to DBT ranged between 1.33 and 3.10, showing a high degree of contamination in sediments of this Chilean bay. All data obtained were analysed by the chemometric method of principal components analysis. A strong correlation was found between TBT and DBT concentrations in sediments, the different organic matter contents in sediments and water. In marine organisms only TBT was detected, containing the filterer organism Semele solida higher level than Perumytilus purpuratus and Pyura chilensis (220, 150 and 120 ng Sn g(-1) dry weight, respectively). For the alga Rodoficea iridae the TBT concentration was 60 ng Sn g(-1) dw. Comparatively, these values are higher than those reported for the same kind of marine organisms worldwide. The different samples from San Vicente Bay were found to be contaminated by TBT. This contamination can be attributed to the different anthropogenic activities taking place in the bay. PMID:18651232

    Suisun Marsh, in northern San Francisco Bay, is the largest brackish marsh in California, and provides critical habitat for many fish species. Storm runoff enters the marsh through many creeks that drain agricultural uplands and the urban areas of Fairfield and Suisun City. Five creeks were sampled throughout a major storm event in February 2014, and analyzed for representatives of several major insecticide classes. Concentrations were greatest in creeks with urban influence, though sampling was done outside of the primary season for agricultural pesticide use. Urban creek waters reached maximum concentrations of 9.9 ng/l bifenthrin, 27.4 ng/l fipronil, 11.9 ng/l fipronil sulfone, 1462 ng/l imidacloprid, and 4.0 ng/l chlorpyrifos. Water samples were tested for toxicity to Hyalella azteca and Chironomus dilutus, and while few samples caused mortality, 70% of the urban creek samples caused paralysis of either or both species. Toxic unit analysis indicated that bifenthrin was likely responsible for effects to H. azteca, and fipronil and its sulfone degradate were responsible for effects to C. dilutus. These results demonstrate the potential for co-occurrence of multiple insecticides in urban runoff, each with the potential for toxicity to particular species, and the value of toxicity monitoring using multiple species. In the channels of Suisun Marsh farther downstream, insecticide concentrations and toxicity diminished as creek waters mixed with brackish waters entering from San Francisco Bay. Only fipronil and its degradates remained measurable at 1-10 ng/l. These concentrations are not known to present a risk based on existing data, but toxicity data for estuarine and marine invertebrates, particularly for fipronil's degradates, are extremely limited.

    Asian women who work at massage parlors in San Francisco have high levels of risk for sexually transmitted infections (STIs), including HIV, and being victims of violence, which jeopardizes their health and wellbeing. On the basis of mapping, the targeted districts in San Francisco where massage parlors were located, 23 massage parlors were identified where commercial sex activity took place. Using snowball-sampling methods, 43 Asian female massage parlor workers were recruited for focus groups; 21 participants were Vietnamese and 22 were Thai. Qualitative analyses revealed frequent exposure to violence including verbal or physical abuse from customers and gang members, as well as persistent HIV risk behaviors associated with multiple daily sex partners, inconsistent condom use with customers, and forced sex. Social factors related to gender, immigration status, and socioeconomic status appeared to be closely tied to the health and wellbeing of Asian masseuses. Study findings suggest that individualized as well as community-level interventions are necessary to improve these women's health and decrease their prolonged exposure to risks for STIs and violence.

    The theoretical characteristics of the electron linear accelerator are: 30 MeV for the energy W{sub S} and 250 mA for the peak current I{sub c}. The main utilization is the intense production of fast neutrons by the reactions ({gamma},n) and ({gamma},f) induced in a target of natural uranium by the accelerated electrons. In the first part of the thesis, relative to the study and the realization of the accelerator, a new equation of dispersion is established analytically when the guide is loaded with round-edged irises. The relation is compared with the equation established by CHU and Hansen, WALKINSHAW, KVASIL in the case of a guide loaded with flat-edged irises. The experimental and theoretical curves of dispersion are compared. The accuracy of every relation of dispersion is estimated. The second part of the thesis is relative to the theoretical study of the electrons dynamics in the guide; it allows the derivation of the parameters of the beam: dispersion of phase, energy, dispersion of energy and the relation W{sub S} = f (I{sub c}). The results relative to the first experiments are given and compared with the theoretical expectations.

  16. Mercury in the mix: An in situ mesocosm approach to assess relative contributions of mercury sources to methylmercury production and bioaccumulation in the Sacramento-San Joaquin Delta

    Mercury (Hg) contamination is considered one of the greatest threats to the Sacramento-San Joaquin Delta and the San Francisco Estuary ecosystems. This threat is driven by the transformation of Hg, deposited in the Delta from erosion of upstream historic mining debris and atmospheric deposition, by native bacteria into the more toxic and biologically available form, methylmercury (MeHg), in the wetlands and sediment of the Delta. To effectively manage this threat, a quantitative understanding of the relative contribution of the different Hg sources to MeHg formation is needed. Mass balance estimates indicate as much as 99% of the Hg entering the Delta arrives via tributary inputs. Of the tributary Hg load, approximately 90% is adsorbed to suspended particles from tributary discharge and 10% is in the dissolved fraction, potentially of atmospheric origin. In comparison, the remaining 1-2% of the Hg entering the Delta arrives through direct atmospheric deposition (wet and dry). The relative importance of these sources to MeHg production within the Delta is not linearly related to the mass inputs because atmospherically-derived Hg is believed to be more reactive than sediment-bound Hg with respect to MeHg formation. We conducted an in situ mesocosm dosing experiment where different Hg sources to the Delta (direct atmospheric, dissolved riverine and suspended sediment) were "labeled" with different stable Hg isotopes and added to mesocosms within four different wetlands. Mercury isotopes added with the streambed sediments were equilibrated in sealed containers for six months; while the Hg isotopes associated with the precipitation and river water were equilibrated for 24 hours prior to use. After adding the isotopes, we sampled the water column, overlying air, bottom sediments and fish (Gambusia) at time intervals up to 30 days. Preliminary results from this experiment suggest that aqueous Hg sources (Hg introduced with precipitation and filtered river water) are 10-1,000x more available to methylating microbes and fish uptake than particle bound Hg. Consequently, although atmospheric Hg deposition may contribute a relatively small portion of the total Hg loading to the Delta, it may contribute to a substantial portion of the MeHg produced within the Delta.

    The works presented in this manuscript are in the field of computer vision, and tackle the problem of real-time vision based localization and 3D reconstruction. In this context, the trajectory of a camera and the 3D structure of the filmed scene are initially estimated by linear algorithms and then optimized by a nonlinear algorithm, bundle adjustment. The thesis first presents a new technique of line search, dedicated to the nonlinear minimization algorithms used in Structure-from-Motion. The proposed technique is not iterative and can be quickly installed in traditional bundle adjustment frameworks. This technique, called Global Algebraic Line Search (G-ALS), and its two-dimensional variant (Two way-ALS), accelerate the convergence of the bundle adjustment algorithm. The approximation of the re-projection error by an algebraic distance enables the analytical calculation of an effective displacement amplitude (or two amplitudes for the Two way-ALS variant) by solving a degree 3 (G-ALS) or 5 (Two way-ALS) polynomial. Our experiments, conducted on simulated and real data, show that this amplitude, which is optimal for the algebraic distance, is also efficient for the Euclidean distance and reduces the convergence time of minimizations. One difficulty of real-time tracking algorithms (monocular SLAM) is that the estimated trajectory is often affected by drifts: on the absolute orientation, position and scale. Since these algorithms are incremental, errors and approximations are accumulated throughout the trajectory and cause global drifts. In addition, a tracking vision system can always be dazzled or used under conditions which prevented temporarily to calculate the location of the system. To solve these problems, we propose to use an additional sensor measuring the displacement of the camera. The type of sensor used will vary depending on the targeted application (an odometer for a vehicle, a lightweight inertial navigation system for a person). We propose to integrate this additional information directly into an extended bundle adjustment, by adding a constraint term in the weighted cost function. We evaluate three methods (based on machine learning or regularization) that dynamically select the weight associated to the constraint and show that these methods can be used in a real time multi-sensor SLAM, and validate them with different types of constraint on the orientation or on the scale. Experiments conducted on real video sequences show that this technique of constrained bundle adjustment reduces the drifts observed with the classical vision algorithms and improves the global accuracy of the positioning system. (author) [French] Les travaux presentes dans ce manuscrit concernent le domaine de la localisation et la reconstruction 3D par vision artificielle. Dans ce contexte, la trajectoire d'une camera et la structure 3D de la scene filmee sont initialement estimees par des algorithmes lineaires puis optimisees par un algorithme non-lineaire, l'ajustement de faisceaux. Cette these presente tout d'abord une technique de recherche de l'amplitude de deplacement (recherche lineaire), ou line search pour les algorithmes de minimisation iterative. La technique proposee est non iterative et peut etre rapidement implantee dans un ajustement de faisceaux traditionnel. Cette technique appelee recherche lineaire algebrique globale (G-ALS), ainsi que sa variante a deux dimensions (Two way-ALS), accelerent la convergence de l'algorithme d'ajustement de faisceaux. L'approximation de l'erreur de reprojection par une distance algebrique rend possible le calcul analytique d'une amplitude de deplacement efficace (ou de deux pour la variante Two way-ALS), par la resolution d'un polynome de degre 3 (G-ALS) ou 5 (Two way-ALS). Nos experimentations sur des donnees simulees et reelles montrent que cette amplitude, optimale en distance algebrique, est performante en distance euclidienne, et permet de reduire le temps de convergence des minimisations. Une difficulte des algorithmes de localisation en temps reel par la vision (SLAM monoculaire) est que la trajectoire estimee est souvent affectee par des derives: derives d'orientation, de position et d'echelle. Puisque ces algorithmes sont incrementaux, les erreurs et approximations sont cumulees tout au long de la trajectoire, et une derive se forme sur la localisation globale. De plus, un systeme de localisation par vision peut toujours etre ebloui ou utilise dans des conditions qui ne permettent plus temporairement de calculer la localisation du systeme. Pour resoudre ces problemes, nous proposons d'utiliser un capteur supplementaire mesurant les deplacements de la camera. Le type de capteur utilise varie suivant l'application ciblee (un odometre pour la localisation d'un vehicule, une centrale inertielle legere ou un systeme de navigation a guidage inertiel pour localiser une personne). Notre approche consiste a integrer ces informations complementaires directement dans l'ajustement de faisceaux, en ajoutant un terme de contrainte pondere dans la fonction de cout. Nous evaluons trois methodes permettant de selectionner dynamiquement le coefficient de ponderation et montrons que ces methodes peuvent etre employees dans un SLAM multi-capteur temps reel, avec differents types de contrainte, sur l'orientation ou sur la norme du deplacement de la camera. La methode est applicable pour tout autre terme de moindres carres. Les experimentations menees sur des sequences video reelles montrent que cette technique d'ajustement de faisceaux contraint reduit les derives observees avec les algorithmes de vision classiques. Ils ameliorent ainsi la precision de la localisation globale du systeme

    Full Text Available Mother and child mortality reflects the level of social and economic development of a country; therefore, reproductive health is a sanitary priority. Mortality prevention depends directly on the coverage and quality of health services. Objective: to assess the compliance of prenatal care with the NOM 007 norm and its correlation with maternal morbidity in a health center located in San Luis Potosí, Mexico. Methodology: a descriptive, correlational, and quantitative study in which the units of analysis were the medical records of 571 pregnant women cared for during 2008. In order to prove the hypothesis, Pearson’s r was used. The p value was ? 0.05. Results: ages ranged from 13 to 43 years. Additionally, 37.1% of the patients were teenagers and 44.3 % began receiving attention during the second trimester of their pregnancy; 38.2 % attended at least five medical appointments, and 46.4 % had morbidity. For the latter group, urinary infection was the most common condition (224 cases. Prenatal attention was adequate in 2.6 % of the cases according to the actions performed. Health promotion actions were the least frequent. Conclusion: the level of compliance with the NOM 007 norm for prenatal care was considered inadequate in 97.4 % of the cases and was consistent with maternal morbidity (87.5-100 %. This could be related to more frequent appointments for some women and with late treatment, which resulted in less time to perform said actions. Contrary to expectations, greater compliance meant higher maternal morbidity (r = 0.318, p < 0.000.

    Full Text Available La historia de la ciudad San Luis Potosí se remonta al siglo XVI. Con el descubrimiento de yacimientos de oro y plata y la presencia de cuerpos de agua en el valle, fue fundada la ciudad San Luis Minas del Potosí, dando lugar a los dos primeros usos de suelo, urbano y minero. A partir del siglo XVII [...] , el uso de suelo agrícola se desarrolló en huertos y fue relegado a la periferia de la zona urbana en el transcurso del tiempo. Finalmente el uso de suelo industrial surgió de manera importante en la segunda mitad del siglo XX. En la actualidad los tres usos de suelo existentes dentro del Valle de San Luis Potosí son el urbano, agrícola e industrial. A través de una campaña de muestreo hidrogeoquímico en octubre de 2008, con 44 muestras de norias y 3 de manantiales dentro del valle, se evaluaron parámetros físico-químicos, cationes, aniones y elementos traza. En los tres usos de suelo en la zona de estudio fueron detectados niveles importantes de nitratos, sulfatos, cloruros, conductividad eléctrica, coliformes totales y fecales; sin embargo, en la zona urbana existen anomalías puntuales de metales pesados principalmente de mercurio, bario, estroncio, cadmio, plomo, fósforo y plata, relacionadas a las antiguas actividades mineras y a la industria activa en la zona. Mientras que en la zona agrícola, la presencia de metales está asociada a los canales a cielo abierto que también reciben agua del Tanque Tenorio y éste a su vez de la zona industrial. En la zona industrial se detectaron grandes anomalías de tipo puntual en casi todos los metales pesados analizados; la principal fuente de estos contaminantes corresponden a un terreno industrial activo. Este trabajo está enfocado a evaluar el impacto que ha generado la actividad antropogénica sobre el acuífero colgado del Valle de San Luis Potosí desde inicios de la fundación de la ciudad hasta la actualidad, utilizando la calidad del agua como herramienta de análisis. Abstract in english The history of San Luis Potosi City dates back to the sixteenth century. With the discovery of gold and silver deposits and the presence of water bodies in the valley, the city of San Luis Minas Potosí was founded, leading to the first two uses of land: urban and mining. From the seventeenth century [...] , agricultural land developed in orchards and, over time, was relegated to the periphery of the urban area. Finally, industrial land use emerged significantly in the second half of the twentieth century. Currently the three existing land uses within the Valley of San Luis Potosi are urban, agricultural and industrial. Through a hydrogeochemical sampling campaign in October 2008 with 44 samples from wells and 3 from springs within the valley, we assessed physical and chemical parameters, cations, anions and trace elements. In the three land uses within the study area, we detected significant levels of nitrates, sulphates, chlorides, electrical conductivity, total and fecal coliforms; but in urban areas there are punctual anomalies of heavy metals, mainly mercury, barium, strontium, cadmium, lead, phosphorus and silver related to former mining and active industry in the area. However, in the agricultural zone, the presence of metals is associated with open channels, which also receive water from the Tanque Tenorio and this in turn from the industrial area. In the industrial area, puntual anomalies were detected in almost all heavy analyzed metals; the main source of these pollutants corresponds to an active industrial area. This work aims to evaluate the impact of anthropogenic activity in the perched aquifer of the Valley of San Luis Potosí since the city's foundation to the present, using water quality as an analytical tool.

  8. Transition de phase quantique de type verrouillage-deverrouillage dans les canaux lineaires coherents des phases en rayures dans les doubles puits quantiques sous champ magnetique perpendiculaire

    Science.gov (United States)

    Faribault, Alexandre

    On peut creer un gaz electronique bidimensionnel en utilisant le potentiel de confinement d'une couche mince d'un semiconducteur dans un substrat fait d'une autre semiconducteur de gap plus eleve. L'ajout d'un champ magnetique perpendiculaire au plan de confinement modifie de facon drastique les proprietes du gaz electronique. Pour des densites et des valeurs du champ magnetique adequatement choisies, on obtient un etat fondamental en onde de densite de charge. Dans un systeme compose de deux de ces gaz bidimensionnels suffisamment rapproches l'un de l'autre, on prevoit theoriquement l'existence d'un etat fondamental compose d'une onde de densite de charge dans chacun des puits et d'une serie de regions lineaires ou l'on a une delocalisation coherente des electrons entre les deux puits. Dans cette these, on etudie le comportement a temperature nulle de cet etat fondamental en rayures coherentes. L'etude numerique des modes collectifs de ces phases laisse croire qu'un deverrouillage des canaux coherents est envisageable dans ce systeme. Afin d'etudier cette possibilite, nous construisons d'abord un modele effectif de canaux quasi-unidimensionnels couples qui permettent de reproduire correctement les excitations collectives a basse energie de la phase en rayures coherentes du double puits quantique. Dans un systeme de coordonnees adequatement choisi, ces excitations peuvent etre decrites par des ondes de pseudospin. Les parametres de ce modele effectif simple peuvent etre extraits des calculs des fonctions de reponse realises dans l'approximation Hartree-Fock dependante du temps (appelee aussi Generalized Random Phase Approximation). On constate l'efficacite de ce modele a decrire la dynamique basse energie du systeme pour une certaine plage de distances inter-puits. En retirant de ce modele les contributions a l'hamiltonien provenant des couplages de type Josephson entre les canaux, on obtient alors un systeme ou les canaux sont deverrouilles. Un traitement en groupe de renormalisation perturbatif des couplages Josephson generaux permet alors de conclure si la phase deverrouillee peut etre stable lorsque l'on traite les fluctuations quantiques qui ne sont pas incluses dans l'approximation GRPA. Ces calculs nous permettent de conclure que la phase en rayures coherentes dans les doubles puits quantiques sous champ magnetique perpendiculaire est telle que les canaux coherents demeurent toujours verrouilles et ce, peu importe la valeur de la distance inter-puits. On envisage par contre que l'ajout d'un biais electrostatique pourrait permettre de modifier les proprietes du double puits de facon telle qu'une phase en rayures deverrouillees puisse etre stabilisee par les fluctuations quantiques.

  9. Spatial distribution of Illex argentinus in San Matias Gulf (Northern Patagonia, Argentina) in relation to environmental variables: A contribution to the new interpretation of the population structuring

    Traditionally, it was assumed that major spawning activity of Illex argentinus occurs in discrete pulses along the outer-shelf/slope off Argentina/southern Brazil during late-fall/winter and that early life stages develop near the Brazil-Malvinas Confluence (BMC). However, a novel hypothesis of the population structuring of the species was proposed that states that coastal waters may be important as spawning and feeding grounds. Here, we analyzed the spatial distribution of Illex argentinus inside San Matias Gulf based on the position of the CPUE of jiggers in order to improve the knowledge of the population structuring in coastal regions. Squids were mainly concentrated on the northern region of the gulf where favorable oceanographic conditions (e.g. water stratification, chlorophyll-a concentration peaks) to feeding and spawning are present. These results provided empirical evidences that individuals of I. argentinus use Argentinean coastal waters, particularly San Matias Gulf, as permanent feeding and spawning grounds which supports the new hypothesis.

  13. SANS studies of polymers

    International Nuclear Information System (INIS)

    Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H2O/D2O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

    Full Text Available Se conoce que la esponja incrustante y excavadora del Caribe Cliona delitrix puede aumentar su abundancia en las cercanías de fuentes de aguas servidas. Para determinar si su notable abundancia actual en los arrecifes de sotavento de la Isla de San Andrés (Caribe SO, Colombia) está relacionada con l [...] a contaminación orgánica generada por las descargas locales de aguas servidas, se obtuvieron datos cuantitativos de densidad y cobertura de esta esponja y otros componentes bentónicos, en transectos de banda y línea en siete estaciones a lo largo de la terraza somera (5- 10 m de profundidad). Se obtuvo mucus de coral para cuantificar la bacteria Escherichia coli, como indicador de la influencia de las plumas de aguas servidas en la biota bentónica. Una regresión potencial negativa entre la cantidad de E. coli en mucus de coral y la distancia del tubo principal de salida de aguas servidas, demostró que las bacterias provienen de los desechos domésticos. Aunque hubo conteos significativos de E. coli solamente hasta 1-2 km de las fuentes de aguas servidas, la influencia general de estas aguas puede extenderse mucho más lejos, ya que se encontraron abundancias moderadas de C. delitrix a lo largo de la terraza somera occidental de San Andrés, aparentemente asociadas con el enriquecimiento general de nutrientes de las aguas servidas. Las abundancias de C. delitrix fueron menores en el suroccidente, lejos de la influencia de aguas servidas, e incrementaron en general hacia las fuentes, pero disminuyeron cerca del tubo de salida principal. Muy cerca de las fuentes de aguas servidas, cualquier efecto positivo en la esponja producido por un aumento en la materia orgánica en suspensión, probablemente es neutralizado por el efecto negativo que el exceso de sedimentación tiene sobre la esponja misma y sobre la cantidad y calidad del sustrato disponible para la colonización. Abstract in english It is known that the encrusting and excavating Caribbean sponge Cliona delitrix may increase its abundance near sources of sewage. To ascertain whether its current conspicuousness in leeward reefs of San Andrés Island (SW Caribbean, Colombia) is related to organic pollution from local raw sewage dis [...] charges, quantitative data on density and cover of this sponge and other benthic components was obtained from belt and line transects at seven stations along the shallow (5-10 m deep) terrace. Coral mucus was sampled to quantify Escherichia coli bacteria, as an approximate indicator of sewage plume influence on benthic biota. A negative multiplicative regression between amount of E. coli in coral mucus and distance from the main raw sewage outlet demonstrated the domestic-wastes origin of the bacteria. Whereas significant E. coli counts occurred only up to 1-2 km from sewage sources, overall sewage influence may extend further as moderate C. delitrix abundances occurred throughout the West shallow terrace of San Andrés, apparently associated to the overall nutrient enrichment from sewage. C. delitrix abundances were lower in the Southwest, farthest from sewage influence, and generally increased towards sewage sources, but decreased near the main sewage outlet. Close to sewage sources, any positive effect on the sponge brought about by the increase in suspended organic matter is probably outweighed by the negative effect that excessive sedimentation has on the sponge itself, and on the quantity and quality of substratum available for settlement.

    Universal stability diagrams have been calculated and experimentally checked for Hill-Meissner type equations with square-wave coefficients. The study of these equations in the phase-plane has then made it possible to extend the periodic solution calculations to the case of non-linear differential equations with periodic square-wave coefficients. This theory has been checked experimentally. For non-linear coupled systems with constant coefficients, a search was first made for solutions giving an algebraic motion. The elliptical and Fuchs's functions solve such motions. The study of non-algebraic motions is more delicate, apart from the study of nonlinear Lissajous's motions. A functional analysis shows that it is possible however in certain cases to decouple the system and to find general solutions. For non-linear coupled systems with periodic square-wave coefficients it is then possible to calculate the conditions leading to periodic solutions, if the two non-linear associated systems with constant coefficients fall into one of the categories of the above paragraph. (author) [French] Pour les equations du genre de Hill-Meissner a coefficients creneles, on a calcule des diagrammes universels de stabilite et ceux-ci ont ete verifies experimentalement. L'etude de ces equations dans le plan de phase a permis ensuite d'etendre le calcul des solutions periodiques au cas des equations differentielles non lineaires a coefficients periodiques creneles. Cette theorie a ete verifiee experimentalement. Pour Jes systemes couples non lineaires a coefficients constants, on a d'abord cherche les solutions menant a des mouvements algebriques. Les fonctions elliptiques et fuchsiennes uniformisent de tels mouvements. L'etude de mouvements non algebriques est plus delicate, a part l'etude des mouvements de Lissajous non lineaires. Une analyse fonctionnelle montre qu'il est toutefois possible dans certains cas de decoupler le systeme et de trouver des solutions generales. Pour les systemes couples non lineaires a coefficients periodiques creneles, il est alors possible de calculer les conditions menant a des solutions periodiques, si les deux systemes non lineaires adjoints a coefficients constants, entrent dans une des categories du paragraphe precedent.

    We examined mercury concentrations and space use of prebreeding Forster's terns (Sterna forsteri) in San Francisco Bay, California, USA, to assess factors influencing mercury levels in piscivorous birds. In 2005 and 2006, we collected blood and feathers from 122 Forster's terns and radio-marked and tracked 72 terns to determine locations of dietary mercury uptake. Capture site and capture date were the most important factors explaining variation in blood mercury concentrations (geometric mean ?? standard error: 1.09 ?? 0.89 ??g/g wet wt), followed by sex and year. Accordingly, radiotelemetry data revealed that Forster's terns generally remained near their site of capture and foraged in nearby salt ponds, managed and tidal marshes, and tidal flats. In contrast, capture site and capture date were not important factors explaining variation in feather mercury concentrations, probably because feathers were grown on their wintering grounds several months prior to our sampling. Instead, sex and year were the most important factors explaining mercury concentrations in breast feathers (9.57 ?? 8.23 ??g/g fresh wt), and sex was the most important factor for head feathers (6.94 ?? 7.04 ??g/g fresh wt). Overall, 13 and 22% of prebreeding Forster's terns were estimated to be at high risk for deleterious effects due to mercury concentrations in blood (>3.0 ??g/g wet wt) and feathers (>20.0 ??g/g fresh wt), respectively. Breeding terns are likely to be even more at risk because blood mercury concentrations more than tripled during the 45-d prebreeding time period. These data illustrate the importance of space use and tissue type in interpreting mercury concentrations in birds. ?? 2008 SETAC.

    Full Text Available There is substantial evidence that the overuse of antibiotics is a major cause for the emergence in antimicrobial resistance. This study analyzes the evolution of antimicrobial resistance to ciprofloxacin and levofloxacin from 2007 to 2008 in some Units of the “San Bassiano” hospital and compares this evolution among the consumption of the same antibiotics. The study involved the collection of all first isolates in blood, urine and transtracheal samples between 2007 and 2008; three microorganisms were chosen: Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Microorganisms investigations concerned Geriatrics, Medicine, Surgery and Intensive Care Unit (ICU with 48, 48, 44 and 10 beds respectively. Identification and antimicrobial susceptibility testing was performed using the Phoenix automated system (Becton Dickinson. If the ciprofloxacin susceptibility was (S and levofloxacin susceptibility was (I/R antimicrobial susceptibility was confirmed by the E-Test method (bioMérieux on Muller Hilton agar and cell density of 0.5 MacFarland. Control strains were E. Coli ATCC 25922, P. aeruginosa ATCC 27853 and S. aureus ATCC 29213. The antibiotics consumed in the hospital between January 2007 and December 2008 were transformed into Defined Daily Dose (DDD, which corresponds to the quantity of antibiotics consumed by a patient in 24 h. Ciprofloxacin and levofloxacin demonstrated a similar pattern of increasing resistance in some units between 2007 and 2008. Fluoroquinolone resistance increase for E. coli, varies from 10% in Geriatrics to 15% in ICU, for S. aureus varies from 15% in Medicine Unit to 5% in ICU. P. aeruginosa maintained the same percentage of resistance from 2007 to 2008, but there was a significantly increase of strains with intermediate sensitivity (I up to 30%. The consumption of Ciprofloxacin didn’t increase in any of the units and in some case decreased. The consumption of levofloxacin increased in every units and particularly in ICU it raised from 5100 ev doses in 2007 to 6480 in 2008 and from 0 to 300 doses os (DDD. The increased consumption of levofloxacin in 2008 in ICU could explain the increased of Pseudomonas aeruginosa strains with intermediate sensitivity (I.

    Using the Vlasov equation we calculate and discuss non-linear coupling equations between three electronic plasma waves (Langmuir waves) which propagate in a cylindrical plasma column confined by a strong magnetic field. We study, in the experimental device EOS, along the magnetic field, the disintegration of a Langmuir wave excited in the plasma column by means of an antenna. Space structure measurements for various waves show that the resonance conditions (selection rules) are satisfied. The measured disintegration threshold is in agreement with the theoretical value within 30 per cent and shows that this non linear mechanism appears when the oscillating density to the mean density ratio is about 10{sup -3} to 10{sup -2}. The variation of the spatial growth rate as a function of the amplitude of the disintegrated wave shows that the resulting waves are correlated in groups of three along the magnetic field even though the disintegrating spectrum appears in a wide frequency band. (author) [French] A partir de l'equation de Vlasov nous calculons et discutons les equations de couplage non lineaire entre trois ondes plasma electroniques (ou ondes de Langmuir) qui se propagent dans une colonne de plasma cylindrique confinee par un champ magnetique de forte intensite. Nous etudions, dans le dispositif experimental EOS, le long du champ magnetique, la desintegration d'une onde de Langmuir excitee dans la colonne de plasma a l'aide d'une antenne. La mesure de la structure spatiale des differentes ondes montre que l'ensemble des conditions de resonance (ou regles de selection) sont satisfaites. Le seuil de desintegration mesure est en accord avec la valeur theorique a 30 pour cent pres et montre que ce mecanisme non lineaire apparait lorsque le rapport de la densite oscillante a la densite moyenne est de l'ordre de 10{sup -3} a 10{sup -2}. La variation du taux de croissance spatiale en fonction de l'amplitude de l'onde qui se desintegre montre que les ondes restent trois par trois fortement correlees le long du champ magnetique bien que le spectre de desintegration apparaisse dans une large bande de frequences.

    The San Joaquin - Tulare Conjunctive Use Model (SANTUCM) was originally developed for the San Joaquin Valley Drainage Program to evaluate possible scenarios for long-term management of drainage and drainage - related problems in the western San Joaquin Valley of California. A unique aspect of this model is its coupling of a surface water delivery and reservoir operations model with a regional groundwater model. The model also performs salinity balances along the tributaries and along the main stem of the San Joaquin River to allow assessment of compliance with State Water Resources Control Board water quality objectives for the San Joaquin River. This document is a detailed description of the various subroutines, variables and parameters used in the model.

    2013-11-01

    Full Text Available The spotted sand bass (Paralabrax maculatofasciatus is an important recreational sport and subsistence food fish within San Diego Bay, a large industrialized harbor in San Diego, California. Despite this importance, few studies examining the species life history relative to pollutant tissue concentrations and the consumptive fishery exist. This study utilized data from three independent spotted sand bass studies from 1989 to 2002 to investigate PCB, DDT, and mercury tissue concentrations relative to spotted sand bass age and growth in San Diego Bay, with subsequent comparisons to published pollutant advisory levels and fishery regulations for recreational and subsistence consumption of the species. Subsequent analysis focused on examining temporal and spatial differences for different regions of San Diego Bay. Study results for growth confirmed previous work, finding the species to exhibit highly asymptotic growth, making tissue pollutant concentrations at initial take size difficult if not impossible to predict. This was corroborated by independent tissue concentration results for mercury, which found no relationship between fish size and pollutant bioaccumulation observed. However, a positive though highly variable relationship was observed between fish size and PCB tissue concentration. Despite these findings, a significant proportion of fish exhibited pollutant levels above recommended state recreational angler consumption advisory levels for PCBs and mercury, especially for fish above the minimum take size, making the necessity of at-size predictions less critical. Lastly, no difference in tissue concentration was found temporally or spatially within San Diego Bay.

    San Miguel volcano, also known as Chaparrastique, is one of many volcanoes along the volcanic arc in El Salvador. The volcano, located in the eastern part of the country, rises to an altitude of about 2130 meters and towers above the communities of San Miguel, El Transito, San Rafael Oriente, and San Jorge. In addition to the larger communities that surround the volcano, several smaller communities and coffee plantations are located on or around the flanks of the volcano, and the PanAmerican and coastal highways cross the lowermost northern and southern flanks of the volcano. The population density around San Miguel volcano coupled with the proximity of major transportation routes increases the risk that even small volcano-related events, like landslides or eruptions, may have significant impact on people and infrastructure. San Miguel volcano is one of the most active volcanoes in El Salvador; it has erupted at least 29 times since 1699. Historical eruptions of the volcano consisted mainly of relatively quiescent emplacement of lava flows or minor explosions that generated modest tephra falls (erupted fragments of microscopic ash to meter sized blocks that are dispersed into the atmosphere and fall to the ground). Little is known, however, about prehistoric eruptions of the volcano. Chemical analyses of prehistoric lava flows and thin tephra falls from San Miguel volcano indicate that the volcano is composed dominantly of basalt (rock having silica content

  9. Status of the San Onofre neutrino oscillation experiment

    International Nuclear Information System (INIS)

    The San Onofre experiment is designed to investigate neutrino oscillations in the parameter space suggested by the atmospheric neutrino problem. A liquid-scintillator-based 12-ton detector will be installed at 650 m from the two units of the San Onofre power reactor. For the detection of the anti ve-induced inverse beta decay reaction a novel four-fold coincidence method is used allowing effective suppression of background at the relatively low shallow depth of 25 mwe. We report on the experimental method and demonstrate its feasibility by presenting results from recent test experiments performed with a prototype detector in the Tendon Gallery of the San Onofre Unit 2 reactor

    The connotations of "du-fu" and "Sanli" in "Sanli acupoint for du-fu diseases" are discussed in this paper, which can provide theoretical foundation for the clinical application of "Sanli acupoint for du-fu diseases". Based on ancient literature combined with related theories in the Huangdi Neijing (Yellow Emperor's Canon of Internal Classic), a deep discussion is performed through the relationship between Zusanli (ST 36) and stomach, indication and mechanism of Zusanli (ST 36) on du-fu diseases and comparison between Zusanli (ST 36) and Shousanli (LI 10). It is believed that "du" should be pronounced as "dÅ­", meaning stomach, and it indicates that Zusanli (ST 36) is closely related to stomach and spleen when it is used for du-fu diseases; "fu" means abdomen area, including liver-gallbladder, spleen, stomach-intestine, kidney, uterus, triple energizer; "sanli' means exclusively the acupoint of Zusanli (ST 36).

  13. Investigation of Quaternary slip rates along the Banning strand of the southern San Andreas Fault near San Gorgonio Pass

    Present-day Pacific-North American relative plate motion in southern California is shared primarily between the San Jacinto and San Andreas faults. At the north end of the Coachella Valley, the San Andreas fault splits into the Banning and Mission Creek strands, which are sub-parallel to each other within the Indio Hills. Northwest of the Indio Hills, the Mission Creek fault diverges from the Banning and continues northwest toward the southeastern San Bernardino Mountains, but loses surface expression beneath Quaternary alluvial deposits in Morongo Wash. The Banning fault, upon exiting the Indio Hills, is deflected toward the west and transitions into a structurally complex fault zone at San Gorgonio Pass, where it is delineated by thrust scarps in Holocene alluvium. The slip rates of the Banning and Mission Creek fault strands northwest of the Indio Hills and southeast of San Gorgonio Pass are presently unconstrained, but understanding how slip is partitioned between these two strands is critical to southern California earthquake forecasting efforts. Here we present preliminary slip rate data for the Banning fault ~2 km southeast of San Gorgonio Pass at Devers Hill. Using the B4 LiDAR as a base, we have mapped the extents of three truncated and offset alluvial fan deposits, which we have differentiated based on both field and remote (LiDAR- and air photo-based) observations of texture: in particular, the distribution of different clast sizes, pavement and soil development, and color and appearance. To confirm across-fault correlation of the displaced deposits, we have measured 26 cosmogenic Be-10 ages from boulders and cobble samples taken from each of the three fan surfaces on both sides of the fault. One debris flow deposit (Q2a) has been dated to ~80 ka, and appears to be offset 1.6-2.2 km, though confirming this reconstruction will depend on future excavations and uranium-series dating of soil carbonate. A second debris flow deposit (Q2b), for which ages are pending, has been displaced 1-1.6 km. Together, these measurements suggest a late Quaternary slip rate for the Banning strand of the San Andreas fault of about 12-24 mm/yr. Our preliminary slip rate measurement for the Banning strand just southeast of San Gorgonio Pass is consistent with the slip rate of the San Bernardino section of the San Andreas fault to the northwest, and suggests that averaged over late Quaternary timescales (~80 ka), displacement along the San Andreas south of San Gorgonio Pass may be more focused on the Banning strand than the Mission Creek strand.

    This Open-File Report is a digital geologic map database. The report serves to introduce and describe the digital data. There is no paper map included in the Open-File Report. The report includes PostScript and PDF plot files that can be used to plot images of the geologic map sheet and explanation sheet. This digital map database is prepared from a previously published map by Dibblee (1973). The geologic map database delineates map units that are identified by general age, lithology, and clast size following the stratigraphic nomenclature of the U.S. Geological Survey. For descriptions of the units, their stratigraphic relations, and sources of geologic mapping, consult the explanation sheet (of99-14_4b.ps or of99-14_4d.pdf), or the original published paper map (Dibblee, 1973). The scale of the source map limits the spatial resolution (scale) of the database to 1:125,000 or smaller. For those interested in the geology of Carrizo Plain and vicinity who do not use an ARC/INFO compatible Geographic Information System (GIS), but would like to obtain a paper map and explanation, PDF and PostScript plot files containing map images of the data in the digital database, as well as PostScript and PDF plot files of the explanation sheet and explanatory text, have been included in the database package (please see the section 'Digital Plot Files', page 5). The PostScript plot files require a gzip utility to access them. For those without computer capability, we can provide users with the PostScript or PDF files on tape that can be taken to a vendor for plotting. Paper plots can also be ordered directly from the USGS (please see the section 'Obtaining Plots from USGS Open-File Services', page 5). The content and character of the database, methods of obtaining it, and processes of extracting the map database from the tar (tape archive) file are described herein. The map database itself, consisting of six ARC/INFO coverages, can be obtained over the Internet or by magnetic tape copy as described below. The database was compiled using ARC/INFO, a commercial Geographic Information System (Environmental Systems Research Institute, Redlands, California), with version 3.0 of the menu interface ALACARTE (Fitzgibbon and Wentworth, 1991, Fitzgibbon, 1991, Wentworth and Fitzgibbon, 1991). The ARC/INFO coverages are stored in uncompressed ARC export format (ARC/INFO version 7.x). All data files have been compressed, and may be uncompressed with gzip, which is available free of charge over the Internet via links from the USGS Public Domain Software page (http://edcwww.cr.usgs.gov/doc/edchome/ndcdb/public.html). ARC/INFO export files (files with the .e00 extension) can be converted into ARC/INFO coverages in ARC/INFO (see below) and can be read by some other Geographic Information Systems, such as MapInfo via ArcLink and ESRI's ArcView.

    Full Text Available La communauté de San Juan est reconnue depuis 1939. Une première partie concerne l’organisation de la reducción de San Juan vers le milieu du XVIe siècle. Le poids fiscal s’exerce durement sur le village et la crise est générale dans toute la vallée du Chancay au XVIIe. siècle. La christianisation des habitants est définitive au milieu de ce même siècle. C’est vers la fin du XVIIe siècle et durant tout le XVIIIe que se multiplient les conflits entre San Juan et les villages voisins liés aux terrains de pâture et à la possession de l’eau. La deuxième partie du travail concerne les rapports de la communauté de San Juan avec le Pérou contemporain : contrainte fiscale toujours très lourde durant la fin de l’époque coloniale, exactions des militaires juste avant l’indépendance. La période républicaine voit toujours les conflits avec les villages voisins mais aussi la naissance de familles qui cherchent à retirer le maximum de la communauté. Les terres sont divisées et attribuées : la détérioration de l’organisation communale traditionnelle est manifeste. L4es conflits se multiplient entre petits propriétaires, mais aussi avec les haciendas voisines : c’est l’apparition d’une véritable lutte de classes. La situation actuelle est incertaine, le poids de l’économie marchande se développe avec l’exode des jeunes. Que sera la communauté San Juan à la fin de ce siècle? La comunidad de San Juan está reconocida desde 1939. La primera parte concierne a la organización de la 'reducción' de San Juan hacia mediados del siglo XVI. El peso fiscal se ejerce duramente sobre el pueblo y en el siglo XVII la crisis es general en todo el valle de Chancay. Hacia mediados del mismo siglo la cristianización de los habitantes es definitiva. Es hacia fines del siglo XVII y durante todo el siglo XVIII que se multiplican los conflictos entre San Juan y los pueblos vecinos, los que están relacionados con los terrenos de pastoreo y la posesión del agua. La segunda parte del trabajo concierne a las relaciones de la comunidad de San Juan con el Perú contemporáneo: obligaciones fiscales cada vez más pesadas hacia fines de la época colonial, exacciones de los militares justamente antes de la independencia. El período republicano ve siempre los conflictos entre los pueblos vecinos pero igualmente el nacimiento de familias que procuran sacar el máximo de la comunidad. Las tierras son divididas y atribuidas: el deterioro de la organización comunal tradicional se pone de manifiesto. Se multiplican los conflictos entre pequeños propietarios, pero también con las haciendas vecinas: es la aparición de una verdadera lucha de clases. La situación actual es incierta, el peso de la economía comercial se desarrolla con el éxodo de los jóvenes. ¿Que será de la comunidad de San Juan a fines de este siglo? San Juan community has been recognized since 1939. In the first part, we will show' the organization of San Juan's reducción at the middle of the XVI century. The fiscal burden on the village was hard and this crisis was general all over the valley of Chancay during the XVII century. Christianisation of the inhabitants was completed in the middle of this same century. It is only at the end of this century and along all the XVII that the conflicts between San Juan and the neighboring villages were multiplied, tied to pasture lands and water possession In the second part, we will show the relations of San Juan with the contemporary Peru: always very hard fiscal constraint at the end of the colonial time and military exactions till the independence. Along the republican period, the conflicts with the neighboring villages persisted but there were also arising families who were trying to take the maximum of the community. Lands were divided and attributed, deterioration of traditional communal organization was visible. Conflicts between small landlords and neighboring haciendas were multiplied A real class struggle appeared. The actual situation seems uncertain but the trading economy burden is developing it with the exode of the youth. What will be of San Juan community at the end of this century?

  3. Preliminary analysis of SANS data from hydrated cement paste

    International Nuclear Information System (INIS)

    Full text: The microstructure of hydrated cement paste is investigated using the technique of Small Angle Neutron Scattering (SANS). The results from SANS measurements are dependent upon the thicknesses of the target materials. Reduction of target thickness is usually not a practical proposition owing to the difficulty in preparing sufficiently thin cement samples and also to the subsequent low count rates of the scattered beam relative to the transmitted beam. In this paper we present a method of analysis that takes advantage of the process of multiple scattering in thick samples. Using cement specimens, which are of different thicknesses, but are otherwise identical, SANS patterns with different degrees of multiple scattering have been obtained. It is shown how these measurements not only provide information about the shape and size of the scattering entities but also provide absolute values of the scattering contrast between the entities responsible for SANS and the matrix. This method of analysis has been used to analyse SANS data from hydrated cement paste. The data were collected on the Ultra High Resolution SANS Diffractometer at Oak Ridge National Laboratory, USA

  5. Complexities of the San Andreas fault near San Gorgonio Pass: Implications for large earthquakes

    Science.gov (United States)

    Yule, Doug; Sieh, Kerry

    2003-11-01

    Geologic relationships and patterns of crustal seismicity constrain the three-dimensional geometry of the active portions of San Andreas fault zone near San Gorgonio Pass, southern California. Within a 20-km-wide contractional stepover between two segments of the fault zone, the San Bernardino and Coachella Valley segments, folds, and dextral-reverse and dextral-normal faults form an east-west belt of active structures. The dominant active structure within the stepover is the San Gorgonio Pass-Garnet Hill faults, a dextral-reverse fault system that dips moderately northward. Within the hanging wall block of the San Gorgonio Pass-Garnet Hill fault system are subsidiary active dextral and dextral-normal faults. These faults relate in complex but understandable ways to the strike-slip faults that bound the stepover. The pattern of crustal seismicity beneath these structures includes a 5-8 km high east-west striking step in the base of crustal seismicity, which corresponds to the downdip limit of rupture of the 1986 North Palm Springs earthquake. We infer that this step has been produced by slip on the linked San Gorgonio Pass-Garnet Hill-Coachella Valley Banning (SGP-GH-CVB) fault. This association enables us to construct a structure contour map of the fault plane. The large step in the base of seismicity downdip from the SGP-GH-CVB fault system probably reflects a several kilometers offset of the midcrustal brittle-plastic transition. (U/Th)/He thermochronometry supports our interpretation that this south-under-north thickening of the crust has created the region's 3 km of topographic relief. We conclude that future large earthquakes generated along the San Andreas fault in this region will have a multiplicity of mostly specifiable sources having dimensions of 1-20 km. Two tasks in seismic hazard evaluation may now be attempted with greater confidence: first, the construction of synthetic seismograms that make useful predictions of ground shaking, and second, theoretical investigations of the role of this complexity in retarding the propagation of future seismic ruptures.

  11. Structure of microemulsions by SANS

    International Nuclear Information System (INIS)

    Small-angle neutron scattering (SANS) has been used to determine the structure of microemulsions in the system hydrocarbon-water-sodium di-ethylhexylsulfosuccinate (AOT). SANS spectra taken in a deuterated solvent showed a perfect Guinier fit with a radius of gyration of 15A regardless of the amount of AOT from 0.1 to 5% present. By varying the proportions of deuterated and undeuterated solvent to vary the contrast between the micelles and the solvent, it is concluded that the micelles are basically monodispersed spherical aggregations of 22 AOT molecules

  1. Sintered materials studied by SANS

    International Nuclear Information System (INIS)

    Complete text of publication follows. The small angle scattering of compacted and sintered single phase materials with open or closed porosity can be described by the two phase model. During sintering, the decrease of pore volume is accompanied with decreasing internal surface measured by SANS [1]. Such investigation can be extended to the field of technically relevant multiphase materials as well, e.g. doped tunsten, SiN ceramics and WC-Co composite made from nano-crystalline powder. The deformation of remaining porosity after sintering can be monitored by 2D anisotropy of SANS distribution as the sintered body is processed through several steps of thermomechanical treatment. The elongation of pores or stable bubbles, e.g. K gas filled bubbles in doped W [2], follows the macroscopic deformation of the body. Heat treatment, however, causes spheroidization with vanishing SANS anisotropy. Our investigation using the isointensity contour map method allows establishing a new description of mechanisms of thermomechanical processing. (author) [1] O. Blaschko, R. Glas, G. Krexner and P.

    Energy Technology Data Exchange (ETDEWEB)

    El Arem, S.

    2006-01-15

    The aim of this work is to study the dynamic response of a cracked rotor to establish some possibilities for early on line crack detection. First, a review on experimental, numerical and analytical works on the dynamics of cracked rotors is given. Then, an original method of calculating the behavior of a cracked beam section in bending with shearing effects is presented. The nonlinear behavior relations are derived from a three-dimensional model taking into account the unilateral contact conditions on the crack's lips. Based on an energy formulation, this method could be applied to any geometry of crack. The exploration by different numerical integration methods of the vibratory response of some models of cracked rotors is presented in the third chapter of this thesis. The un-cracked parts of a rotor are represented by elements of bar or beam type, and the cracked section by a nonlinear spring taking into account the breathing mechanism of the cracks. At the end of this part, an original method of construction of a finite element of a cracked beam is presented. The final chapter is devoted to the analytical study of the system with 2 degrees of freedom. The breathing mechanism of the crack is taken into account by considering specific periodic variation of the global stiffness of the system. The differential equations system is solved using the harmonic balance method. The linear stability of the periodic solutions is studied by the Floquet theory. Some vibratory parameters are proposed as crack indicators. (author)

    Full Text Available Se estudió la diversidad y relaciones entre diferentes poblamientos de la biocenosis de raspadores-suspensívoros del golfo San José (Chubut, Argentina: 42º20’S; 64º20’W), con énfasis en los bancos de cholga Aulacomya atra atra. Las relaciones entre poblamientos se estudiaron a través de un análisis [...] de correspondencias sin tendencias y las relaciones entre poblamientos y factores ambientales a través de un análisis factorial de correspondencias. Para el estudio de la diversidad se utilizaron los índices de diversidad de Hill (N0, N1 y N2), así como el índice de uniformidad derivado (E=N2/N1). Se analizaron, dentro del contexto de estos poblamientos, las relaciones entre la diversidad observada con la resistencia a los disturbios, la presencia de depredadores y con la sucesión y aumento de la heterogeneidad espacial. Se concluyó que: (1) Los bancos de cholga sobre sustratos duros, en razón de hallarse en sitios protegidos del oleaje producido por vientos locales y con una matriz física fijada firmemente a la roca mantienen una alta riqueza específica y una alta uniformidad. (2) Los poblamientos de fondos blandos de mejillón Mytilus edulis platensis en condiciones de estabilidad, evolucionan hacia bancos mixtos con cholgas lo que implica aumento en la complejidad del sustrato, en la heterogeneidad espacial del banco y en la riqueza específica. Estos bancos mixtos al quedar sujetos a disturbios físicos revertirían el proceso de sucesión. (3) Los bancos de vieira tehuelche Aequipecten tehuelchus son propios de ambientes permanentemente disturbados por movimientos del agua y poseen características de baja uniformidad y baja riqueza específica. Con disturbios intensos e infrecuentes estos bancos son eliminados del sitio que ocupaban, ocasionándose arribazones de las especies desprendidas.

The ordination analysis of the assembla [...] ges species composition was performed using detrended correspondence analysis and the relationships of the assemblages with the environmental factors were analysed using factorial correspondence analysis. The Hill diversity indices (N0, N1, N2), and the evenness derived index (E=N2/N1) were calculated. It was concluded that: (1) The ribbed mussel beds on hard sustrate have high species richness and high equitability, because the rocks provides firm surfaces for byssal attachment and these beds are usually found in protected localities. (2) The soft bottom assemblages with the mussel Mytilus edulis platensis, under conditions of environmental stability, evolve towards mixed beds with ribbed mussel; this process implies increased sustrate complexity, increased spatial heterogeneity and higher species richness. This successional process can be reverted if the mixed bed are affected by strong physical disturbance which can dislodge the assemblages. (3) Beds of the scallop Aequipecten tehuelchus are found at sites permanently disturbed by waves generated by local winds, they have low equitability and low species richness. When the environmental disturbance is very intense the bed is dislodged and big quantities of individuals are beach stranded. (4) The mixed beds of ribbed mussel and Aequipecten tehuelchus are facies which are alternative to Aequipecten beds and they are found in protected sites

    Full Text Available In order to synthesize the exploration of above presented ideas, wesuggest the following conclusions: Pope John Paul II cherished Saint Thomas as representing „that eternal novelty of thinking” which brought us close to the ontic space of knowledge, the dynamic principle of which is Being. The climax of this condition would be the moment of embracing the truth, which would trigger that vital necessity for metaphysics. According to the stated objective ofthe necessary and indispensable ratio between reason and faith, we see that Tomas suggested the vision of the objective, transcendent and universal truth. This fact determined Pope John Paul II to appreciate that “passion” for truth. The man of our time must walk again towards the light of this truth. In this sense, Saint Thomas’ philosophy represents the guide above all. Its philosophic importance, meaning that “it is truly the philosophy of Being, and not the philosophy of a simple epiphany”, confirms its aim to provide a constant answerto many of the problems that concerns the human mind: the problems ofknowledge and Being, the problems of speaking and doing, the problems of the world, and the problems related with Man and God.

  10. San Onofre - the evolution of outage management

    International Nuclear Information System (INIS)

    With the addition of units 2 and 3 to San Onofre nuclear station in 1983 and 1984, it became evident that a separate group was needed to manage outages. Despite early establishment of a division to handle outages, it was a difficult journey to make the changes to achieve short outages. Early organizational emphasis was on developing an error-free operating environment and work culture. This is difficult for a relatively large organization at a three-unit site. The work processes and decision styles were designed to be very deliberate with many checks and balances. The organization leadership and accountability were focused in the traditional operations, maintenance, and engineering divisions. Later, our organization emphasis shifted to achieving engineering excellence. With a sound foundation of operating and engineering excellence, our organizational focus has turned to achieving quality outages. This means accomplishing the right work in a shorter duration and having the units run until the next refueling

  14. Beneficial Reuse of San Ardo Produced Water

    Energy Technology Data Exchange (ETDEWEB)

    2006-07-31

    This DOE funded study was performed to evaluate the potential for treatment and beneficial reuse of produced water from the San Ardo oilfield in Monterey County, CA. The potential benefits of a successful full-scale implementation of this project include improvements in oil production efficiency and additional recoverable oil reserves as well as the addition of a new reclaimed water resource. The overall project was conducted in two Phases. Phase I identified and evaluated potential end uses for the treated produced water, established treated water quality objectives, reviewed regulations related to treatment, transport, storage and use of the treated produced water, and investigated various water treatment technology options. Phase II involved the construction and operation of a small-scale water treatment pilot facility to evaluate the process's performance on produced water from the San Ardo oilfield. Cost estimates for a potential full-scale facility were also developed. Potential end uses identified for the treated water include (1) agricultural use near the oilfield, (2) use by Monterey County Water Resources Agency (MCWRA) for the Salinas Valley Water Project or Castroville Seawater Intrusion Project, (3) industrial or power plant use in King City, and (4) use for wetlands creation in the Salinas Basin. All of these uses were found to have major obstacles that prevent full-scale implementation. An additional option for potential reuse of the treated produced water was subsequently identified. That option involves using the treated produced water to recharge groundwater in the vicinity of the oil field. The recharge option may avoid the limitations that the other reuse options face. The water treatment pilot process utilized: (1) warm precipitation softening to remove hardness and silica, (2) evaporative cooling to meet downstream temperature limitations and facilitate removal of ammonia, and (3) reverse osmosis (RO) for removal of dissolved salts, boron, and organics. Pilot study results indicate that produced water from the San Ardo oilfield can be treated to meet project water quality goals. Approximately 600 mg/l of caustic and 100 mg/l magnesium dosing were required to meet the hardness and silica goals in the warm softening unit. Approximately 30% of the ammonia was removed in the cooling tower; additional ammonia could be removed by ion exchange or other methods if necessary. A brackish water reverse osmosis membrane was effective in removing total dissolved solids and organics at all pH levels evaluated; however, the boron treatment objective was only achieved at a pH of 10.5 and above.

  19. Developing solar power programs : San Francisco's experience

    International Nuclear Information System (INIS)

    This keynote address discussed an array of solar programs initiated in government-owned buildings in San Francisco. The programs were strongly supported by the city's mayor,and the voting public. Known for its fog and varying microclimates, 11 monitoring stations were set up throughout the city to determine viable locations for the successful application of solar technologies. It was observed that 90 per cent of the available sunshine occurred in the central valley, whereas fog along the Pacific shore was problematic. Seven of the monitoring sites showed excellent results. Relationships with various city departments were described, as well as details of study loads, load profiles, electrical systems, roofs and the structural capabilities of the selected government buildings. There was a focus on developing good relations with the local utility. The Moscone Convention Center was selected for the program's flagship installation, a 675 kW solar project which eventually won the US EPA Green Power Award for 2004 and received high press coverage. Cost of the project was $4.2 million. 825,000 kWh solar electricity was generated, along with 4,500,000 kWh electricity saved annually from efficiency measures, resulting in a net reduction of 5,325,000 kWh. Savings on utilities bills for the center were an estimated $1,078,000. A pipeline of solar projects followed, with installations at a sewage treatment plant and a large recycling depot. A program of smaller sites included libraries, schools and health facilities. Details of plans to apply solar technology to a 500 acre redevelopment site in southeast San Francisco with an aging and inadequate electrical infrastructure were described. A model of efficient solar housing for the development was presented, with details of insulation, windows, heating ventilation and air-conditioning (HVAC), water heating, lighting, appliances and a 1.2 kilowatt solar system. Peak demand reductions were also presented. tabs., figs

  5. SANS (USH1G) expression in developing and mature mammalian retina.

    The human Usher syndrome (USH) is the most common form of combined deaf-blindness. Usher type I (USH1), the most severe form, is characterized by profound congenital deafness, constant vestibular dysfunction and prepubertal-onset of retinitis pigmentosa. Five corresponding genes of the six USH1 genes have been cloned so far. The USH1G gene encodes the SANS (scaffold protein containing ankyrin repeats and SAM domain) protein which consists of protein motifs known to mediate protein-protein interactions. Recent studies indicated SANS function as a scaffold protein in the protein interactome related to USH. Here, we generated specific antibodies for SANS protein expression analyses. Our study revealed SANS protein expression in NIH3T3 fibroblasts, murine tissues containing ciliated cells and in mature and developing mammalian retinas. In mature retinas, SANS was localized in inner and outer plexiform retinal layers, and in the photoreceptor cell layer. Subcellular fractionations, tangential cryosections and immunocytochemistry revealed SANS in synaptic terminals, cell-cell adhesions of the outer limiting membrane and ciliary apparati of photoreceptor cells. Analyses of postnatal developmental stages of murine retinas demonstrated SANS localization in differentiating ciliary apparati and in fully developed cilia, synapses, and cell-cell adhesions of photoreceptor cells. Present data provide evidence that SANS functions as a scaffold protein in USH protein networks during ciliogenesis, at the mature ciliary apparatus, the ribbon synapse and the cell-cell adhesion of mammalian photoreceptor cells. Defects of SANS may cause dysfunction of the entire network leading to retinal degeneration, the ocular symptom characteristic for USH patients. PMID:17923142

  7. RheoSANS: simultaneous SANS and rheology measurements on the Quokka SANS instrument

    International Nuclear Information System (INIS)

    The highly penetrative and non-ionising nature of neutrons make the SANS measurement particularly suited to examine toe response of soft materials to an external stimulus. In this case we consider the response of a complex fluid. an aqueous solution of a block co-polymer. to shear flow in a couette cell consisting of two concentric quartz cylinders with a variable gap between The couette shear cell is connected to a commercial Paar Physica MCR 500 rheometer. Depending on the ability to maintain laminar flow, rheometric tests may be performed at shear rates from 0.1 to 2000s-1 and at temperatures from -5 to 80cC. The jacket responsible for thermal control of the sample allows access of neutron beam in directions radial and tangential to the now direction. In the tangential direction the need to use a highly collimated beam to illuminate the gap provides a serious limitation to neutron flux at the sample. A trap may be used to prevent the evaporation of solvents. SANS data from the detector may be acquired in either of two modes. Acquisitions may be triggered by voltage output from rheometer (e.g shear rate), or using the detector in list mode where detector counts are post-binned to provide the optimal signal to noise for example in kinetic studies. A further possibility of the latter mode rs the study of shear induced structural changes in a steady perturbed slate such as an oscillatory smear.

  9. SANS study of asphaltene aggregation

    International Nuclear Information System (INIS)

    The colloidal properties of asphaltenes affects their solubility, reactivity and transport properties. We have been investigating the molecular basis for the aggregation of asphaltenes in toluene through the use of Small Angle Neutron Scattering (SANS), in which the hydrogen nucleus provides the strongest scatterer, and the contrast may be varied by deuterium replacement. The measured intensity curves can be fitted with a elongated particle. Both radius of gyration and molecular weight are significantly decreased upon increasing temperature, indicating a disaggregation rather than a conformational change mechanism. Thus, the ''true'' molecular weight of asphaltenes is much less than that measured at room temperature, and appears to be ≤6000. The internal structure is probably complex enough so that a simple description in terms of colloidal or micellar structures is not granted

    Ocean Beach in San Francisco, California, contains a persistent erosional section in the shadow of the San Francisco ebb tidal delta and south of Sloat Boulevard that threatens valuable public infrastructure as well as the safe recreational use of the beach. Coastal managers have been discussing potential mediation measures for over a decade, with little scientific research available to aid in decision making. The United States Geological Survey (USGS) initiated the Ocean Beach Coastal Processes Study in April 2004 to provide the scientific knowledge necessary for coastal managers to make informed management decisions. This study integrates a wide range of field data collection and numerical modeling techniques to document nearshore sediment transport processes at the mouth of San Francisco Bay, with emphasis on how these processes relate to erosion at Ocean Beach. The Ocean Beach Coastal Processes Study is the first comprehensive study of coastal processes at the mouth of San Francisco Bay.

  13. Moving Towards SAN Storage: An Enterprise Perspective

    Full Text Available Abstract – One of the major components of any enterprise IT infrastructure is data storage. There has been continuous effort to explore new storage technologies to improve performance with respect to input/output operations, data availability, consolidation of storage assets and data protection and archiving. Storage has moved from the traditional Direct Attached Storage (DAS to Network Attached Storage (NAS and now to Storage Area Networks (SAN. Traditional storage subsystems like Server Attached Storage (SAS and Network Attached Storage (NAS use disks directly attached to servers over a Small Computer Systems Interface (SCSI bus. However, these have limited capabilities keeping in view the rapidly expanding storage needs. The SAN technology holds great promises to be used for enterprises where issues like data availability, serviceability, consolidation of storage and reliability are major concerns. It can provide high speed data transfer with many other storage services, backboned with a high speed Fibre Channel (FC. Storage-area networks are also more popular and efficient way of building large storage systems both in an enterprise environment and for multi-domain storage service providers. SAN design and implementation requires careful analysis before SAN can be used as an enterprise storage solution. In this paper we provide an overview of SAN technology from the view point of building large storage systems in an enterprise environment. We also discuss on return on investment (ROI which can justify the adoption of SAN in an enterprise. Further, it compares two specific technologies, namely, FC SAN and IP SAN. In the sequel different design considerations are made to recommend suitable SAN implementations in order to meet the requirements of any enterprise.

    International Nuclear Information System (INIS)

    Small-angle neutron scattering (SANS) has proved to be an excellent technique for the study of complex fluids. This article introduces SANS from the viewpoint of such studies. The use of SANS to determine the structures of concentrated micellar fluids is then discussed within the framework of current one-component macrofluid (OCM) models, and experimental examples are taken from several contemporary studies. Finally, the discussion is extended to magnetic fluids (ferrofluids) in which the neutron magnetic interaction plays an important experimental role. 25 refs., 11 figs., 1 tab

    The theory of relativity has become a cornerstone of modern physics. Over the course of time it has been scrutinized in a multitude of experiments and has always been verified with high accuracy. The correctness of this theory can no longer be called into question. Right after its discovery by Albert Einstein in 1905, special relativity was only gradually accepted because it made numerous predictions contradicting common sense, fervently castigated by Einstein, and also defied experiment for too long a time. It was only with the advent of particle or high energy physics that matter could be ac

    Time magazine's ""Man of the Century"", Albert Einstein is the founder of modern physics and his theory of relativity is the most important scientific idea of the modern era. In this short book, Einstein explains, using the minimum of mathematical terms, the basic ideas and principles of the theory that has shaped the world we live in today. Unsurpassed by any subsequent books on relativity, this remains the most popular and useful exposition of Einstein's immense contribution to human knowledge.With a new foreword by Derek Raine.

    2009-01-01

    We report small angle neutron scattering (SANS) experiments on two crude oils. Analysis of the high-Q SANS region has probed the asphaltene aggregates in the nanometer length scale. We find that the radius of gyration decreases with increasing temperature. We show that SANS measurements on crude oils give similar aggregate sizes to those found from SANS measurements of asphaltenes redispersed in deuterated toluene. The combined use of SANS and V-SANS on crude oil samples has allowed the determination of the radius of gyration of large scale asphaltene aggregates of approximately 0.45 microm. This has been achieved by the fitting of Beaucage functions over two size regimes. Analysis of the fitted Beaucage functions at very low-Q has shown that the large scale aggregates are not simply made by aggregation of all the smaller nanoaggregates. Instead, they are two different aggregates coexisting. PMID:19063643

    Sediment plays an important role in the ecological health of rivers and estuaries and consequently is an important issue for water-resource managers. To better understand sediment characteristics in the San Antonio River Basin, the U.S. Geological Survey, in cooperation with the San Antonio River Authority, completed a two-part study in the San Antonio River Basin downstream from San Antonio, Texas, to (1) collect and analyze sediment data to characterize sediment conditions and (2) develop and calibrate a watershed model to simulate hydrologic conditions and suspended-sediment loads during 2000–12.

  18. Miocene and Pleistocene mollusks from San Andres Island (Caribbean Sea, Colombia) and Paleogeographic considerations

    International Nuclear Information System (INIS)

    San Andres Island is the largest emerged portion of the oceanic archipelago of San Andres and Providencia, southwestern Caribbean Sea; it originated as a coralline atoll during Miocene times. The central and highest part of the island consists of a calcareous crest, the San Andres Formation, formed by Neogene lagoonal and reefal deposits. This crest is surrounded by a calcareous platform of Pleistocene age (San Luis Formation) which emerges only along the island coast, whereas its most part is submerged and covered by a Recent reef complex. Fossil material of molluscs from these two formations was collected in various sites throughout the island and taxonomically identified. In the four sites sampled in the San Andres Formation, material belonging to 19 gastropod and 37 bivalve species was obtained, most of them relatively well represented in other geologic formations of the Caribbean region that are stratigraphically situated between the upper Miocene and the middle Pliocene. Some elements occurring in this formation, such as Ostrea haitiensis, Meretrix dariena and Siphocypraea henekeni, were widely distributed in the Caribbean Miocene Province. In the San Luis Formation, material belonging to 18 gastropod and 11 bivalve species was obtained, most of them also represented in the Recent molluscan fauna of the region. The estimated age of this formation is Sangamonian, hence corresponding to similar formations occurring in Grand Cayman, Jamaica, Hispaniola, the Netherlands Antilles and other Caribbean islands, with which it also shows a great similarity in the composition of the molluscan fauna.

    Full Text Available Currently, the environmental decision-making related to watershed preservation is oriented under the precepts of an historical environmental assessment. The objective of this research was to conduct a historical ecotoxicological assessment of the San Juan de Santiago de Cuba ecosystem. This was considered a systematic environmental monitoring which ran from 2010 to 2013, made q?uarterly. Physicochemical parameters such as electrical conductivity, total alkalinity, total hardness, pH, total solids, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were determined. All parameters of environmental risk prediction were performed using the GECOTOX program. The concentrations of Cu, Zn, Pb and Cd on three target organs (brain, gills and liver in the biomonitor adult Gambusia punctata (Poecilidae were analyzed. In this species, the effect of total protein and enzymatic activity of acetylcholinesterase as biomarkers were evaluated. In general, the parameters were outside the values set used by the Cuban quality standards. The GECOTOX program said that the waters of the San Juan ecosystem presented a high rate of risk. The highest concentrations of metals were determined in the gills, liver and brain, respectively. Biomarker values w? ere high, being higher for females. Finally, it was concluded that from one year to another all responses were ascending; thus, the San Juan ecosystem presented ecotoxicological effects in time.

  20. San Onofre Unit 1 decommissioning

    International Nuclear Information System (INIS)

    Nuclear plant decommissioning presents several challenges in radiation protection. The plant demolition must consider radiation protection for workers, protection of the public, and careful material management. Decommissioning of the San Onofre Nuclear Generating Station (SONGS) Unit 1 presented some additional challenges. Including complete removal of above ground structures this can be accomplished safely and efficiently. None of the low-level radioactive waste is unique to decommissioning although transportation of large components can be a significant challenge. Proven techniques are available to handle Greater than Class C waste (highly activated reactor internals) and spent fuel. A considerable challenge is the disposing of the very large volume of potentially clean material. There is a high cost to survey and decontaminate materials. Moreover, in the US today there are no standards for the clearance of potentially contaminated volumetric materials. Careful planning is necessary to determine the most cost-effective means for waste management, whether it includes decontamination and surveys or simple disposal. Lastly, existing ALARA programs with some minor modifications provide sufficient worker and public protection from radiation

  2. Long Return Periods for Earthquakes in San Gorgonio Pass and Implications for Large Ruptures of the San Andreas Fault in Southern California

    Science.gov (United States)

    Yule, J.; McBurnett, P.; Ramzan, S.

    2011-12-01

    The largest discontinuity in the surface trace of the San Andreas fault occurs in southern California at San Gorgonio Pass. Here, San Andreas motion moves through a 20 km-wide compressive stepover on the dextral-oblique-slip thrust system known as the San Gorgonio Pass fault zone. This thrust-dominated system is thought to rupture during very large San Andreas events that also involve strike-slip fault segments north and south of the Pass region. A wealth of paleoseismic data document that the San Andreas fault segments on either side of the Pass, in the San Bernardino/Mojave Desert and Coachella Valley regions, rupture on average every ~100 yrs and ~200 yrs, respectively. In contrast, we report here a notably longer return period for ruptures of the San Gorgonio Pass fault zone. For example, features exposed in trenches at the Cabezon site reveal that the most recent earthquake occurred 600-700 yrs ago (this and other ages reported here are constrained by C-14 calibrated ages from charcoal). The rupture at Cabezon broke a 10 m-wide zone of east-west striking thrusts and produced a >2 m-high scarp. Slip during this event is estimated to be >4.5 m. Evidence for a penultimate event was not uncovered but presumably lies beneath ~1000 yr-old strata at the base of the trenches. In Millard Canyon, 5 km to the west of Cabezon, the San Gorgonio Pass fault zone splits into two splays. The northern splay is expressed by 2.5 ± 0.7 m and 5.0 ± 0.7 m scarps in alluvial terraces constrained to be ~1300 and ~2500 yrs old, respectively. The scarp on the younger, low terrace postdates terrace abandonment ~1300 yrs ago and probably correlates with the 600-700 yr-old event at Cabezon, though we cannot rule out that a different event produced the northern Millard scarp. Trenches excavated in the low terrace reveal growth folding and secondary faulting and clear evidence for a penultimate event ~1350-1450 yrs ago, during alluvial deposition prior to the abandonment of the low terrace. Subtle evidence for a third event is poorly constrained by age data to have occurred between 1600 and 2500 yrs ago. The southern splay at Millard Canyon forms a 1.5 ± 0.1 m scarp in an alluvial terrace that is inset into the lowest terrace at the northern Millard site, and therefore must be < ~1300 yrs old. Slip on this fault probably occurred during the most recent rupture in the Pass. In summary, we think that the most recent earthquake occurred 600-700 yrs ago and generated ~6 m of slip on the San Gorgonio Pass fault zone. The evidence for two older earthquakes is less complete but suggests that they are similar in style and magnitude to the most recent event. The available data therefore suggest that the San Gorgonio Pass fault zone has produced three large (~6 m) events in the last ~2000 yrs, a return period of ~700 yrs assuming that the next rupture is imminent. We prefer a model whereby a majority of San Andreas fault ruptures end as they approach the Pass region from the north or the south (like the Wrightwood event of A.D. 1812 and possibly the Coachella Valley event of ~A.D. 1680). Relatively rare (once-per-millennia?), through-going San Andreas events break the San Gorgonio Pass fault zone and produce the region's largest earthquakes.

  3. Abrupt along-strike change in tectonic style: San Andreas fault zone, San Francisco Peninsula

    Science.gov (United States)

    Zoback, M.L.; Jachens, R.C.; Olson, J.A.

    1999-01-01

    Seismicity and high-resolution aeromagnetic data are used to define an abrupt change from compressional to extensional tectonism within a 10- to 15-km-wide zone along the San Andreas fault on the San Francisco Peninsula and offshore from the Golden Gate. This 100-km-long section of the San Andreas fault includes the hypocenter of the Mw = 7.8 1906 San Francisco earthquake as well as the highest level of persistent microseismicity along that ???470-km-long rupture. We define two distinct zones of deformation along this stretch of the fault using well-constrained relocations of all post-1969 earthquakes based a joint one-dimensional velocity/hypocenter inversion and a redetermination of focal mechanisms. The southern zone is characterized by thrust- and reverse-faulting focal mechanisms with NE trending P axes that indicate "fault-normal" compression in 7- to 10-km-wide zones of deformation on both sides of the San Andreas fault. A 1- to 2-km-wide vertical zone beneath the surface trace of the San Andreas is characterized by its almost complete lack of seismicity. The compressional deformation is consistent with the young, high topography of the Santa Cruz Mountains/Coast Ranges as the San Andreas fault makes a broad restraining left bend (???10??) through the southernmost peninsula. A zone of seismic quiescence ???15 km long separates this compressional zone to the south from a zone of combined normal-faulting and strike-slip-faulting focal mechanisms (including a ML = 5.3 earthquake in 1957) on the northernmost peninsula and offshore on the Golden Gate platform. Both linear pseudo-gravity gradients, calculated from the aeromagnetic data, and seismic reflection data indicate that the San Andreas fault makes an abrupt ???3-km right step less than 5 km offshore in this northern zone. A similar right-stepping (dilatational) geometry is also observed for the subparallel San Gregorio fault offshore. Persistent seismicity and extensional tectonism occur within the San Andreas right stepover region and at least 15 km along-strike both to the SE and NW. The 1906 San Francisco earthquake may have nucleated within the San Andreas right stepover, which may help explain the bilateral nature of rupture of this event. Our analysis suggests two seismic hazards for the San Francisco Peninsula in addition to the hazard associated with a M = 7 to 8 strike-slip earthquake along the San Andreas fault: the potential for a M ??? 6 normal-faulting earthquake just 5-8 km west of San Francisco and a M = 6+ thrust faulting event in the southern peninsula.

  4. San Onofre unit 1 water hammer event

    International Nuclear Information System (INIS)

    San Onofre Unit 1 experienced a severe water hammer event in the main feedwater (MFW) system on November 21, 1985. Southern California Edison (SCE) performed an extensive investigation and evaluation to determine the cause and effect of the event. The most significant finding was that five MFW system check valves had degraded to an inoperable condition prior to the event. The inoperable check valves caused the formation of a water hammer in the B MFW line which, in turn, caused a reactor trip transient to escalate into a more serious event. The water hammer created a MFW system leak which affected the capability of the auxiliary feedwater system to perform its safety-related shutdown function. Moderate damage was sustained in the MFW and Condensate system including the rupture of the evaporator heater and flash chamber shell (a 21-foot long split in the weld seam). In spite of the MFW system leak and damage, the inherent redundance and defense in depth built into the plant allowed the operators to shut down and stabilize the plant in a timely and orderly manner

El análisis estadístico fue realizado STATA 12.0. Un 51,8% es población femenina, con una edad media de 42,26 (DE 16,5). Un 91,97%, percibe que la salud oral afecta su calidad de vida, siendo levemente mayor en mujeres. Las molestias psicológicas son una manifestación en 80,29% de los encuestados. Un 75,91% percibe incomodidad por dolor en su boca, 62,77% manifiesta problemas de incapacidad psicológica. Existe mayor impacto en la calidad de vida relacionada con salud oral a medida que aumenta la edad. Por cada año de vida, el valor del OHIP-14 aumenta 0,07 (IC:95% 0,04­0,1). Los resultados obtenidos sugieren la necesidad de generar políticas públicas que consideren la salud oral desde una perspectiva integral, con énfasis en poblaciones altamente vulnerables considerando la mejora en la calidad de vida como un resultado a esperar. Abstract in english Geographic isolation and environmental conditions make the population of Robinson Crusoe Island, in the Juan Fernández archipielago highly vulnerable. It is therefore relevant to know the quality of life related to oral health (QOLRTO). In this report a cross sectional study in 137 inhabitants over [...] 14 years of age was carried out. OHIP-14 was applied to measure QOLRTO, after informed consent was obtained. Statistical analysis was made in STATA 12.0. The population is 51.8% female, mean age 42.26 (SD 16.5) being similar in both sexes. Of the subjects studied, 91.97% perceived that oral health affects their quality of life, being slightly higher in women. Psychological distress was a manifestation in 80.29% of subjects, while 75.91% perceived discomfort and mouth pain, and 62.77% reported psychological disability issues. There is a greater impact of oral health issues with increasing age. For each year of life, the value of the OHIP-14 increased 0.07 (CI 95%, 0.04 to 0.1). The results suggest that public health policies that include a comprehensive oral health perspective, with emphasis on highly vulnerable populations should be considered.

  4. Une République islamique sans mosquée

    Full Text Available Qui dit mosquée en Iran dit d’abord un ensemble de moyens ou de facilités laissés au quotidien à la disposition des passants ou des usagers. Ensuite des rituels religieux accomplis, de façon régulière, en présence des autorités ayant le privilège ou le monopole de délivrer un certain savoir islamique. Dans le premier sens la mosquée est un point d’eau, un toit, un accueil où nul(le ne se sentirait exclu(e ou ne se verrait refoulé(e. Dans le second sens elle relève des choix du croyant qui peut préférer un lieu par rapport à un autre, en fonction de critères aussi bien intellectuels que religieux ou encore de type communautaire, professionnel, voire générationnel. C’est sans doute la concomitance même de ces deux formes d’utilité, matérielle et spirituelle, qui font que les mosquées ont résisté, d’une part, au monopole, de l’autre, à l’isolement. Autrement dit, si les mosquées ont servi de cadre à la centralisation de l’Etat, elles ont également été des instances de résistance à la prétention monopolistique de ce dernier. Le présent travail tente une analyse des dynamiques concomitantes, spirituelles et matérielles, qui se renforcent et se complètent, à partir de la nouvelle organisation des mosquées et des nouvelles pratiques qui se déroulent en leur sein ou dans leur proximité. De fait il convient mieux, depuis une vingtaine d’années, de parler de complexes religieux plutôt que de simples lieux de prière.

    2012-12-01

    Full Text Available Storage replication is one of the back bones for network environments. While many forms of Network Attached Storage (NAS, Storage Area Networks (SAN and other forms of network storage exist, there is a need for a reliable storage replication technique between distant sites (> 1 Km. Such technology allows setting new standards and removes demerits of network failover and failback systems for virtual servers; specifically, the growing storage need for effective disaster recovery (DR planning. The purpose of this manuscript is to identify growing technologies such as IP-SAN that allow with remote storage cluster replication for virtual servers. This study (Cluster Replication provides an analysis of improving the uptime and availability of SAN. For higher levels of availability, mirrored images maintained in Active/Active Cluster mirroring can provide a system with No Single Points of Failure, which is designed to improve the overall uptime of the storage system for organizations with 7x24x365 requirements.

    2011-05-24

    Mesoamerican peoples had a long history of cacao use--spanning more than 34 centuries--as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, and documents assorted vessels forms used in its preparation and consumption. One elite context reveals cacao use as part of a mortuary ritual for sacrificial victims, an event that occurred during the height of San Lorenzo's power. PMID:21555564

    For measuring the diverse characteristic parameters of a Linac electron beam, the one method causing the least perturbation to the electron beam itself, consists in the detection of signals induced in certain types of detectors by the electromagnets fields associated with the beam. Some particular detectors are then described, for measuring the following characteristic parameters of a Linac electron beam; a) electron beam peak current, a) longitudinal dimension and density of an elementary electron bunch, c) phase position of the electrons on the travelling sine wave of the accelerating field, d) transverse position of the beam. These particular electrodes are then used to provide experimental data In order to check the theoretical computations giving the longitudinal and transversal motions Of the electrons during their acceleration. (author) [French] Parmi les methodes de mesure des diverses caracteristiques du faisceau d'electrons d'un accelerateur lineaire, celles qui perturbent le moins le faisceau sont les methodes dans lesquelles l'energie du signal de mesure provient de la perturbation par l'electrode de mesure des champs electromagnetiques associes au faisceau. On decrit les electrodes de ce type qui ont ete mises au point pour mesurer les caracteristiques suivantes du faisceau d'electrons: a) courant crete, b) extension en phase d'un paquet elementaire d'electrons, c) phase d'accrochage des electrons, d) position transversale moyenne des electrons. On decrit ensuite comment les signaux provenant de ces diverses electrodes peuvent etre utilises pour verifier experimentalement les previsions theoriques des mouvements longitudinaux et transversaux des electrons en cours d'acceleration.

  9. Chlorinated hydrocarbon pesticides and polychlorinated biphenyls in sediment cores from San Francisco Bay

    1999-01-01

    Sediment cores of known chronology from Richardson and San Pablo Bays in San Francisco Bay, CA, were analyzed for a suite of chlorinated hydrocarbon pesticides and polychlorinated biphenyls to reconstruct a historic record of inputs. Total DDTs (DDT = 2,4'- and 4,4'-dichlorodiphenyltrichloroethane and the metabolites, 2,4'- and 4,4'-DDE, -DDD) range in concentration from 4-21 ng/g and constitute a major fraction (> 84%) of the total pesticides in the top 70 cm of Richardson Bay sediment. A subsurface maximum corresponds to a peak deposition date of 1969-1974. The first measurable DDT levels are found in sediment deposited in the late 1930's. The higher DDT inventory in the San Pablo relative to the Richardson Bay core probably reflects the greater proximity of San Pablo Bay to agricultural activities in the watershed of the Sacramento and San Joaquin rivers. Total polychlorinated biphenyls (PCBs) occur at comparable levels in the two Bays (sediment deposited during the 1930's in Richardson Bay, about a decade earlier than the onset of detectable levels of DDTs. PCB inventories in San Pablo Bay are about a factor of four higher in the last four decades than in Richardson Bay, suggesting a distribution of inputs not as strongly weighed towards the upper reaches of the estuary as DDTs. The shallower subsurface maximum in PCBs compared to DDT in the San Pablo Bay core is consistent with the imposition of drastic source control measures four these constituents in 1970 and 1977 respectively. The observed decline in DDT and PCB levels towards the surface of both cores is consistent with a dramatic drop in the input of these pollutants once the effect of sediment resuspension and mixing is taken into account.

  16. Radium 228 distribution and mixing in San Nicolas and San Pedro Basins, southern California borderland

    International Nuclear Information System (INIS)

    Sediment profiles of 228Ra and 232Th and water column profiles of 228Ra are presented for San Nicolas and San Pedro Basins, located in the Southern California Borderland. These data are used to estimate fluxes of 228Ra from the sediments, the vertical eddy diffusivity (Kz) in the water column, and the upwelling velocity (wz). The fluxes of 228Ra from sediments, estimated by integrating the downcore deficiency of 228Ra with respect to its parent nuclide 232Th, are 335 ± 115 atoms/m2s for San Nicolas Basin and 166 ± 50 atom/m2s for San Pedro Basin. San Nicolas Basin sediments have an excess of 228Ra in the upper 4 cm, but irrigation and diffusion create a 228Ra deficiency from 4 to 30 cm. San Pedro Basin sediments are anoxic and laminated, have a 228Ra deficiency above 6-12 cm depth, and have no surface excess of 228Ra. Basin waters appear to be well-mixed horizontally below sill depth and in steady-state with respect to 228Ra. Concentrations of 228Ra increase from sill depth to the bottom, ranging from approximately 1.0 dpm/100 kg to 2.4 dpm/100 kg in San Nicolas Basin and from 1.6 dpm/100 kg to 3.1 dpm/100 kg in San Pedro Basin. Estimates of Kz and wz at several horizons in these basins are made by evaluating two steady state mass balance equations, one for 228Ra and one for heat. Upper limits for Kz are 23 cm2/s at 1,700 m in San Nicolas and 2.8 cm2/s at 850 m in San Pedro Basin. The best estimate for Kz and wz for the deeper part of the basins are: Kz = 5-17 cm2/s and wz = 50-150 m/y in San Nicolas Basin, and Kz = 1-3 cm2/s and wz = 20-50 m/y in San Pedro Basin

In the San Pedr [...] o River, the "Central Hidroeléctrica San Pedro" (San Pedro Hydroelectric Plant) is planned, whose dam is located 14 km downstream from the outlet of the Riñihue Lake, which will transform 12.5 km of river in a reservoir. This generated the need for an Environmental Impact Assessment, which was developed by the Center for Environmental Sciences EULA-Chile (Universidad de Concepción). In relation to the river ecology, the study placed special emphasis on generating detailed knowledge about their ichthyofauna, in order to make a species-specific impact assessment. In this issue, we present the foundations and methodological approaches to undertake the intensive study, whose results give rise to this monograph and to the description of the distribution, abundance, habitat use, movement patterns, length-weight relationships, early life stages and genetic structure of the fish fauna of San Pedro River.

  1. Psychiatric Disorders and Substance Use in Homeless Youth: A Preliminary Comparison of San Francisco and Chicago

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Youth homelessness is a growing problem in the United States. The experience of homelessness appears to have numerous adverse consequences, including psychiatric and substance use disorders. This study compared the frequencies of psychiatric disorders, including substance use, between homeless youth (18–24 years-old in San Francisco (N = 31 and Chicago (N = 56. Subjects were administered the Mini International Neuropsychiatric Interview (M.I.N.I. to assess DSM-IV-TR diagnoses and substance use disorders. Eighty-seven percent of the San Francisco youth, and 81% of the Chicago youth met criteria for at least one M.I.N.I. psychiatric diagnosis. Nearly two-thirds of the youth in both samples met criteria for a mood disorder. Approximately one-third met criteria for an anxiety disorder. Thirty-two percent of the San Francisco sample and 18% of the Chicago met criteria for Antisocial Personality Disorder. Approximately 84% of the San Francisco youth and 48% of the Chicago youth met criteria for a substance-related disorder, and more substances were used by San Francisco youth. In conclusion, the high rate of psychiatric disorders in homeless youth provides clear evidence that the mental health needs of this population are significant. Implications are discussed.

  10. Isotopic Evidence of Nitrate Sources and its Relationship to Algae in the San Joaquin River, California

    Many competing demands have been placed on the San Joaquin River including deep water shipping, use as agricultural and drinking water, transport of agricultural and urban runoff, and recreation. These long-established demands limit the management options and increase the importance of understanding the river dynamics. The relationships among sources of water, nitrate, and algae in the San Joaquin River must be understood before management decisions can be made to optimize aquatic health. Isotopic analyses of water samples collected along the San Joaquin River in 2005-2007 have proven useful in assessing these relationships: sources of nitrate, the productivity of the San Joaquin River, and the relationship between nitrate and algae in the river. The San Joaquin River receives water locally from wetlands and agricultural return flow, and from three relatively large tributaries whose headwaters are in the Sierra Nevada. The lowest nitrate concentrations occur during periods of high flow when the proportion of water from the Sierra Nevada is relatively large, reflecting the effect of dilution from the big tributaries and indicating that a large fraction of the nitrate is of local origin. Nitrogen isotopes of nitrate in the San Joaquin River are relatively high (averaging about 12 per mil), suggesting a significant source from animal waste or sewage and/or the effects of denitrification. The d15N of nitrate varies inversely with concentration, indicating that these high isotopic values are also a local product. The d15N values of nitrate from most of the local tributaries is lower than that in the San Joaquin suggesting that nitrate from these tributaries does not account for a significant fraction of nitrate in the river. The source of the non-tributary nitrate must be either small unmeasured surface inputs or groundwater. To investigate whether groundwater might be a significant source of nitrate to the San Joaquin River, groundwater samples are being collected monthly from over 20 bank and in-stream wells. Preliminary data suggest that much of the groundwater nitrate has been variably denitrified thereby increasing its d15N values, but not by enough to account for the high d15N values in the river nitrate. The d15N of algae in the San Joaquin reflects the high values of the nitrate in the river indicating (1) that the San Joaquin is productive despite its relatively high opacity, (2) that the algae use the nitrate as a primary nutrient source, and (3) that the concentrations of algae in the San Joaquin are not principally dependent on algae from the tributaries being flushed into the river as has been suggested. The sources of nitrate to the San Joaquin River must be identified if algae production is to be controlled and hypoxic conditions in the downstream reaches eliminated.

    San Martín Tuxtla (N18.562°; W95.199°, 1659 masl) is a basaltic volcano located in southern Veracruz, a Mexican State bordering the Gulf of Mexico. It rises in a volcanic field strewn with monogenetic volcanic cones, maars and three other large volcanoes mostly dormant since the late Pliocene: Santa Marta, San Martín Pajapan and Cerro El Vigía. The latest eruptive event of San Martín occurred in 1793 and was described by Don José Mariano Moziño, a naturalist under the commission of the Viceroy of the then New Spain. In this work we present results of the study of this eruption based on historical accounts and field observations. We identified an ash deposit around the volcano related to the 1793 eruption, mapped its distribution and determined its granulometric, petrographic and geochemical characteristics. These studies suggest that the volcano began its activity with explosive phreatomagmatic explosions, which were followed by Strombolian activity; this period lasting from March to October 1793. The activity continued with an effusive phase that lasted probably 2 years. The eruption covered an area of about 480 km 2 with at least 1 cm of ash; the fines reaching distances greater than 300 km from the crater. A total mass of about 2.5 × 10 14 g was ejected and the volcanic columns probably reached altitudes of the order of 10 km during the most explosive phases. The lava emitted formed a coulee that descended the northern flank of the volcano and has an approximate volume of 2.0 × 10 7 m 3.

  2. Sediment geochemistry of Corte Madera Marsh, San Francisco Bay, California: have local inputs changed, 1830-2010?

    Science.gov (United States)

    Takesue, Renee K.; Jaffe, Bruce E.

    2013-01-01

    Large perturbations since the mid-1800s to the supply and source of sediment entering San Francisco Bay have disturbed natural processes for more than 150 years. Only recently have sediment inputs through the Sacramento-San Joaquin Delta (the Delta) decreased to what might be considered pre-disturbance levels. Declining sediment inputs to San Francisco Bay raise concern about continued tidal marsh accretion, particularly if sea level rise accelerates in the future. The aim of this study is to explore whether the relative amount of local-watershed sediment accumulating in a tidal marsh has changed as sediment supply from the Sacramento-San Joaquin Rivers has decreased. To address this question, sediment geochemical indicators, or signatures, in the fine fraction (silt and clay) of Sacramento River, San Joaquin River, San Francisco Bay, and Corte Madera Creek sediment were identified and applied in sediment recovered from Corte Madera Marsh, one of the few remaining natural marshes in San Francisco Bay. Total major, minor, trace, and rare earth element (REE) contents of fine sediment were determined by inductively coupled plasma mass and atomic emission spectroscopy. Fine sediment from potential source areas had the following geochemical signatures: Sacramento River sediment downstream of the confluence of the American River was characterized by enrichments in chromium, zirconium, and heavy REE; San Joaquin River sediment at Vernalis and Lathrop was characterized by enrichments in thorium and total REE content; Corte Madera Creek sediment had elevated nickel contents; and the composition of San Francisco Bay mud proximal to Corte Madera Marsh was intermediate between these sources. Most sediment geochemical signatures were relatively invariant for more than 150 years, suggesting that the composition of fine sediment in Corte Madera Marsh is not very sensitive to changes in the magnitude, timing, or source of sediment entering San Francisco Bay through the Delta. Nor does there appear to be a ubiquitous increase in the proportion of fine sediment from Corte Madera watershed accumulating in the marsh during the last 20 years when sediment inflows through the Delta have decreased to pre-disturbance levels. We conclude that a large, well-mixed reservoir, such as the transportable fine sediment pool in San Francisco Bay, is the primary source of sediment to Corte Madera Marsh, and this source buffers the marsh against changes in sediment supply from the Delta and local watersheds. This study also found that Corte Madera Marsh sediment between about 10-30 centimeters depth is highly contaminated with lead, likely a legacy of lead smelter operations near Carquinez Strait and leaded gasoline use.

  3. El impacto psicosocial de la violencia en San Salvador / The psychosocial impact of violence in San Salvador

    1999-04-01

    Full Text Available En este estudio se busca lograr dos objetivos: primero, describir los niveles de victimización de la población salvadoreña a causa de la violencia delictiva y el tipo de población más afectada por ella; segundo, averiguar si estos niveles de victimización están relacionados con la presencia de norma [...] s, actitudes y comportamientos que favorecen la aparición de la violencia. Para ello se utilizaron los datos del proyecto ACTIVA de El Salvador, que fue realizado por el Instituto Universitario de Opinión Pública entre los meses de octubre y noviembre de 1996 con una muestra de 1 290 entrevistas personales, presuntamente representativa de las personas entre los 18 y 70 años de edad que residen en el Área Metropolitana de San Salvador. La muestra se obtuvo mediante un muestreo probabilístico y multietápico. Los resultados revelan que el nivel de victimización por la violencia es bastante alto en San Salvador y que afecta sobre todo a los hombres y a los jóvenes, y sugieren que las personas que han sido víctimas de agresiones graves suelen mostrar con más frecuencia que el resto normas de justificación y aprobación del uso de la violencia, inclinación por el uso de armas, y conductas de agresión hacia otras personas. Abstract in english This study had two objectives: (1) to describe the levels of victimization of Salvadorians due to criminal violence, and the population groups most affected by it; (2) to learn if these levels of victimization are related to the presence of norms, attitudes, and behaviors that encourage the occurren [...] ce of violence. For this purpose data from the ACTIVA project of El Salvador were used. The project was carried out by the University Institute of Public Opinion during October and November 1996, with a sample of 1 290 personal interviews that were presumed to be representative of people between 18 and 70 years of age living in the Metropolitan Area of San Salvador. The sample was obtained through multistage probability sampling. The results show that the level of victimization from violence is quite high in San Salvador and that it especially affects adult and young men. The results also indicate that persons who have been victims of serious aggression tend to show, more frequently than average, norms justifying and approving the use of violence, a tendency to use weapons, and aggressive behaviors toward other people.

    The San Cristobal Galapagos wind power project was described. With its unique endemic flora and fauna, the Galapagos Islands were declared a world heritage site and marine reserve. The San Cristobal wind project was initiated in 1999 to reduce the environmental impacts of energy use on the island, and has been operational since 2007. Three 800 kW wind turbines have been installed in order to reduce 52 per cent of the island's diesel generation. The project's high penetration wind-diesel hybrid system included 300 kW diesel generators, a 13.2 kV utility distribution system, and six 300 kW wind turbines. The project is located outside of Galapagos Petrel flight paths and nesting areas. Turbines from a factory in Spain were used. The wind turbine foundation was constructed from concrete sand and stone mined on the island. Photographs of the installation process were included. tabs., figs.

  7. San Rafael mining and fabrication complex today

    International Nuclear Information System (INIS)

    In Mendoza province, 35 km West San Rafael city, is located a CNEA installation for uranium ore extraction and concentration: the San Rafael Mining and Fabrication Complex. By the middle of the nineties, as a consequence of the very low prices of uranium concentrate in the international market and of the high internal production costs, uranium extraction was stopped. To day, the international price of the concentrate had a very important increase and the Government has decided the completion of the Atucha II Nuclear Power Station construction. Moreover, studies have been started for new nuclear power plants. In such circumstances the reactivation of the Complex will make sure the uranium supply for our nuclear power stations, contributing to the improvement of the energy generation mix in our country.

    2006-03-27

    Salt management has been a challenge to westside farmerssince the rapid expansion of irrigated agriculture in the 1900 s. Thesoils in this area are naturally salt-affected having formed from marinesedimentary rocks rich in sea salts rendering the shallow groundwater,and drainage return flows discharging into the lower reaches of the SanJoaquin River, saline. Salinity problems are affected by the importedwater supply from Delta where the Sacramento and San Joaquin Riverscombine. Water quality objectives on salinity and boron have been inplace for decades to protect beneficial uses of the river. However it wasthe selenium-induced avian toxicity that occurred in the evaporationponds of Kesterson Reservoir (the terminal reservoir of a planned but notcompleted San Joaquin Basin Master Drain) that changed public attitudesabout agricultural drainage and initiated a steady stream ofenvironmental legislation directed at reducing non-point source pollutionof the River. Annual and monthly selenium load restrictions and salinityand boron Total Maximum Daily Loads (TMDLs) are the most recent of thesepolicy initiatives. Failure by both State and Federal water agencies toconstruct a Master Drain facility serving mostly west-side irrigatedagriculture has constrained these agencies to consider only In-Valleysolutions to ongoing drainage problems. For the Westlands subarea, whichhas no surface irrigation drainage outlet to the San Joaquin River,innovative drainage reuse systems such as the Integrated Farm DrainageManagement (IFDM) offer short- to medium-term solutions while morepermanent remedies to salt disposal are being investigated. Real-timesalinity management, which requires improved coordination of east-sidereservoir releases and west-side drainage, offers some relief toGrasslands Basin farmers and wetland managers - allowing greater salinityloading to the River than under a strict TMDL. However, currentregulation drives a policy that results in a moratorium on all drainagereturn flows.

    According to the cooperation between Beijing, San Juan and La Plata Astronomical Observatories, the photoelectric astrolabe Mark II(PAII) of the Beijing Astronomical Observatory was moved and installed at the San Juan Observatory, Argentina in January, 1992 for observations of the catalogue of stars in the southern hemisphere. The first observing period was from Feb. 23, 1992 to Mar. 31, 1997. Using the data observed in San Juan with the instrument during this period, residuals for 11002 stars are reduced from about 405700 observations of stars over 1532 days. The mean precision of the residuals is +/-0.043''. The Second Catalogue of Stars (CPASJ2) has been compiled from double transits at both the eastern and western passages. There are 5241 stars in this catalogue, including 1225 FK5/FK4Supp stars, 794 FK5Ext stars, 1084 SRS stars, 937 CAMC4 stars, 310 GC stars and 891 IMF stars. The mean precisions are +/-3.2ms and +/-0.057'' in right ascension and declination, respectively. The magnitudes of stars are from 2.0 to 11.5. The declinations are from -3(deg) to -60(deg) . The mean epoch is 1994.9. Finally, systematic corrections of(CPASJ2-FK5) are given.

    2010-11-25

    As part of our research endeavour aimed at developing and improving decontamination processes of wastewater containing alpha emitters, physico-chemical complexation studies of actinides (U, Pu, Am) with organic open-chain ligands such as poly-aminocarboxylic acids (H{sub 4}EDTA) and sidero-chelates (di-hydroxamic acids and desferrioxamine B) have been carried out. Gaining a clear understanding of the coordination properties of the targeted actinides is an essential step towards the selection of the most appropriate chelating agents that will exhibit high uptake efficiencies. EXAFS (Extended X-ray Absorption Fine Structure) measurements at the ESRF synchrotron enabled to elucidate the coordination scheme of uranium and plutonium complexes. Solution thermodynamic investigations were intended to provide valuable information about the nature and the stability of the uranium(VI) and americium(III) complexes prevailing at a given pH in solution. The set of stability constants determined from potentiometric and UV-visible spectrophotometric titrations, allowed to predict the speciation of the selected actinides in presence of the aforementioned ligands and to determine the pH range required for achieving 'ultimate' decontamination.

  19. Late Glacial and Holocene Record of Hydroclimate in the San Luis Valley, Southern Colorado, USA

    Lake sediments from the San Luis Valley, south-central Colorado, archive a detailed record of Late Glacial and Holocene climatic fluctuations in the southern Rocky Mountains. Together with radiometric dating analysis, measurements of grain size, magnetic susceptibility, total inorganic carbon (TIC), oxygen and carbon isotopic composition of the TIC fraction on sediment samples from San Luis Lake (at an average resolution of 60 years per sample) allow us to generate a sediment record of climatic change in the region spanning the last 16ka (1 ka=1000 cal yrs). This record documents the timing and duration of major climate episodes and trends, comparable to the existing paleoclimate records from the American Southwest. The Late Glacial record of San Luis Lake contains a big wet episode in the late part of the Mystery Interval (MI), a relatively dry climate during Bølling-Allerød (B/A) warm interval, and a relatively wet episode during the Younger Dryas (YD) interval, similar to the lake-level record found in the Estancia basin in central New Mexico. The early to middle Holocene record of d18O in the San Luis Lake parallels the calcite d18O record of Bison Lake in northern Colorado, documenting a history of significant change in precipitation seasonality across the northern boundary of the North American monsoon (NAM). The middle Holocene epoch is characterized by greater variations in magnetic susceptibility, d18O and d13C, suggesting the prevalence of wet, variable or transitional climate conditions. In contrast, the late Holocene climate is relatively dry, as indicated by more positive values of d18O in San Luis Lake. The results of this study reveal a complex history of climate evolution due to the interactions of two seasonally distinct precipitation regimes with mountainous landforms in the region.

  1. Development of 40m SANS and Its Utilization Techniques

    International Nuclear Information System (INIS)

    Small angle neutron scattering (SANS) has been a very powerful tool to study nanoscale (1-100 nm) bulk structures in various materials such as polymer, self assembled materials, nano-porous materials, nano-magnetic materials, metal and ceramics. Understanding the importance of the SANS instrument, the 8m SANS instrument was installed at the CN beam port of HANARO in 2001. However, without having a cold neutron source, the beam intensity is fairly low and the Q-range is rather limited due to short instrument length. In July 1, 2003, therefore, the HANARO cold neutron research facility project was launched and a state of the art 40m SANS instrument was selected as top-priority instrument. The development of the 40m SANS instrument was completed as a joint project between Korea Advanced Institute of Science and Technology and the HANARO in 2010. Here, we report the specification of a state of art 40m SANS instrument at HANARO

  3. Sans study of asphaltene aggregation

    International Nuclear Information System (INIS)

    The colloidal properties of asphaltenes have long been recognized from peculiarities in their solubility and colligative properties. A layered micellar model or asphaltenes was proposed by others in which a highly condensed alkyl aromatic formed the central part, and molecules of decreasingly aromatic character (resins) clustered around them. Numerous studies, based on a variety of techniques such as ultracentrifugation and electron microscopy indicated a particulate nature for asphaltenes with size 20-40 A diameter. Others have proposed a refined model based on x-ray diffraction and small angle scattering. In this model, interactions between flat sheets of condensed aromatic rings form the central ''crystallite'' part of a spherical particle with the outer part being comprised of the aliphatic positions of the same molecules. These particles are bunched together with some degree of entanglement into ''micelles''. Concentration and solvent dependent radii of gyration, ranging from 30-50 A were reported. The aggregation creates a good deal of uncertainty as to the true molecular size or weight of asphaltenes. Neutron scattering offers novel contrast relative to light scattering (refractive index) and x-ray scattering (electron density). This is because the scattering length of proton is negative, whereas that from deuterium and other nuclei such as C, S, O, and N are positive. Thus by replacing hydrogen with deuterium in either the solvent or the scatterer the contrast can be varied, and different parts of the molecule can be highlighted

  6. Ruptures of the San Andreas fault system in San Gorgonio Pass

    Science.gov (United States)

    Yule, D.; Sieh, K. E.

    2010-12-01

    Fault behavior models for the San Andreas fault system in San Gorgonio Pass hinge upon contrasting interpretations of the structural complexity and diffuse seismicity in the Pass region. One model maintains that the fault system can rupture through the Pass in ~ M 7.8 earthquakes that extend from the Salton Sea to the Mojave Desert. Another model argues that the structural complexity here arrests San Andreas ruptures as they approach from either side of the Pass and limits their size to ~ M 7.5. One way to test these models is to examine the paleoseismic record of active faults in the Pass. Work at the Burro Flats site, located where the San Bernardino strand feeds into San Gorgonio Pass from the north, reveals evidence for at least nine earthquakes in the last 2000 yrs. The average earthquake recurrence is about 200 yrs with the maximum and minimum intervals between earthquakes equal to about 550 and 80 yrs, respectively. The average recurrence is considered to be a maximum value because a hiatus in sedimentation during the Early Middle Ages may ‘hide’ one or more event during this time period. The maximum recurrence interval of 550 yrs is likely an overestimate owing to the large errors in the timing of one event ~1300 yrs ago. In general, the Burro Flats event record and average recurrence is very similar to those at sites in the San Bernardino and Coachella Valley regions. The most recent rupture at Burro Flats cuts strata that contain European-introduced pollen and is interpreted to record the southeastern extent of the 1812 Wrightwood earthquake, a possible example of a ‘Pass-as-a-barrier’, moderate-sized event. The timing of pre-1812 events at Burro Flats correlate with the timing of San Andreas events in the San Bernardino and Coachella Valley regions, possible examples of through going, larger-sized earthquakes. Work at the Cabezon site, located on a thrust segment of the San Gorgonio Pass fault zone, shows evidence for two ruptures since ~ AD 1300. Age data permit correlating the two events at Cabezon with the second and third events at Burro Flats, assuming that the 1812 earthquake died out between the Burro Flats and Cabezon sites. Another test of the likelihood of a through going rupture is the analysis of fault steps in the Pass region. Mapping of the active faults here shows that fault steps are smaller than the 3-4 km limit that has halted historic ruptures worldwide, and within the size range where ruptures cease only ~40 per cent of the time. Though the 1812 earthquake appears to have stopped within the Pass, active fault maps in combination with paleoseismic data cannot preclude that very large, through going San Andreas earthquakes happen in San Gorgonio Pass.

  9. SANS study of hydrophobic effects on pressure-induced micro- and macrophase separations of block copolymers

    International Nuclear Information System (INIS)

    Hydrophobic effects on pressure-induced microphase separation of block copolymers were investigated by using small-angle neutron scattering (SANS). A block copolymer, pEOEOVE-b-pMOVE aqueous solution, which shows LCSTs (at 40 and 60 deg. C, for pEOEOVE and pMOVE homopolymers, respectively) was used. A phase diagram was obtained by tracing light-transmittance at 632.8nm by increasing temperature (T) at various pressures (P), which was a convex-upward function. The change in the slope of the phase boundary curve could be explained by volume change associated with mixing as well as 'iceberg' formation. SANS revealed that a microphase separation took place by pressurizing or increasing temperature. At 28 deg. C, the correlation length was observed to show continuous increase with divergence at 350MPa. This result showed that the block copolymers at 28 deg. C underwent macrophase separation and the transition was a second-order transition. At 45 deg. C, under atmospheric pressure, the SANS curve suggested formation of a BCC lattice structure with micelles composed of a central core of pEOEOVE. By pressurizing, the SANS peak related to the microphase separation disappeared, meaning dissolution of block copolymers. However, by further pressurizing, another peak re-appeared at 250MPa. This peak indicates the microphase separation of block copolymers is different from those observed under low pressures

  10. SANS experiments and molecular dynamics studies of asphaltenes : driving force and morphology of nano-aggregation

    Small-angle scattering experiments have shown that asphaltenes form nanoaggregates, but their shape, arrangement and the driving force behind their formation are not well understood. This study used SANS experiments to probe the shape of the asphaltene nanoaggregates in toluene solution and crude oil. Molecular Dynamics simulations of model asphaltene structures were used to discover the most probable morphology of asphaltene molecules in nanoaggregates and the nature and strength of the driving force behind aggregation. SANS experiments were conducted on heptane extracted asphaltenes in d8-toluene and on a crude oil. In addition, V-SANS experiments were conducted on the crude oil. Potential of Mean Force (PMF) calculations between pairs of asphaltene molecules were conducted in baths of explicit solvent molecules, both toluene and heptane. The free energy of aggregation was found to be approximately -8 kJ mol-1. There was little difference between the PMF curves in toluene and heptane, indicating that the nano-aggregation process is relatively independent of solvent. This implies that it is larger scale aggregation seen in the V-SANS experiments that occurs in heptane and does not occur in toluene. Larger simulations were also conducted for 6 asphaltene molecules in a box of solvent at 7wt per cent asphaltene. Preliminary results showed that aggregation does occur spontaneously. Further analysis of the simulations is ongoing to determine the most probable morphology of asphaltene aggregates. 2 refs.

  11. Characterization of Tight Gas Reservoir Pore Structure Using USANS/SANS and Gas Adsorption Analysis

    2012-01-01

    Small-angle and ultra-small-angle neutron scattering (SANS and USANS) measurements were performed on samples from the Triassic Montney tight gas reservoir in Western Canada in order to determine the applicability of these techniques for characterizing the full pore size spectrum and to gain insight into the nature of the pore structure and its control on permeability. The subject tight gas reservoir consists of a finely laminated siltstone sequence; extensive cementation and moderate clay content are the primary causes of low permeability. SANS/USANS experiments run at ambient pressure and temperature conditions on lithologically-diverse sub-samples of three core plugs demonstrated that a broad pore size distribution could be interpreted from the data. Two interpretation methods were used to evaluate total porosity, pore size distribution and surface area and the results were compared to independent estimates derived from helium porosimetry (connected porosity) and low-pressure N{sub 2} and CO{sub 2} adsorption (accessible surface area and pore size distribution). The pore structure of the three samples as interpreted from SANS/USANS is fairly uniform, with small differences in the small-pore range (< 2000 {angstrom}), possibly related to differences in degree of cementation, and mineralogy, in particular clay content. Total porosity interpreted from USANS/SANS is similar to (but systematically higher than) helium porosities measured on the whole core plug. Both methods were used to estimate the percentage of open porosity expressed here as a ratio of connected porosity, as established from helium adsorption, to the total porosity, as estimated from SANS/USANS techniques. Open porosity appears to control permeability (determined using pressure and pulse-decay techniques), with the highest permeability sample also having the highest percentage of open porosity. Surface area, as calculated from low-pressure N{sub 2} and CO{sub 2} adsorption, is significantly less than surface area estimates from SANS/USANS, which is due in part to limited accessibility of the gases to all pores. The similarity between N{sub 2} and CO{sub 2}-accessible surface area suggests an absence of microporosity in these samples, which is in agreement with SANS analysis. A core gamma ray profile run on the same core from which the core plug samples were taken correlates to profile permeability measurements run on the slabbed core. This correlation is related to clay content, which possibly controls the percentage of open porosity. Continued study of these effects will prove useful in log-core calibration efforts for tight gas.

    Silica gels under study are materials intended for use as the packing sorbents in liquid chromatography (LC), namely in gel permeation chromatography (GPC). The quality of silica for LC should meet strict physical and chemical parameters. Especially in GPC is very important to know pore size and pore shape because they control the whole process of chromatographic separation. Pore size and thickness of pore wall can be measured by various methods. SANS technique is a nondestructive method providing an average information about a large number of scattering object in our case about objects (pore or wall) in silica and their shape. (author)

    Month-to-month variations in the early morning surface-based and near-noon elevated inversions at San Jose, Calif., were determined from slow rise radiosondes launched during a four-year period. A high frequency of shallow, radiative, surface-based inversions were found in winter during the early morning hours, while during the same period in summer, a low frequency of deeper based inversions arose from a combination of radiative and subsidence processes. The frequency of elevated inversions in the hours near noon was lowest during fall and spring, while inversion bases were highest and thicknesses least during these periods.

    The self-assembly of the ??-precipitates in superalloy during thermo-mechanical exposure can be used to produce a nanoporous material by a selective phase dissolution. Nanoporous superalloy (CMSX4) samples, containing narrow channel-like pores, were investigated by high-resolution small-angle neutron scattering (SANS) in order to observe a time dependence of the pore depth during etching. The mean distance of pores and their depths were determined. A saturation of the pore depth with etching time was observed.

  14. Early Maya writing at San Bartolo, Guatemala.

    Science.gov (United States)

    Saturno, William A; Stuart, David; Beltrán, Boris

    2006-03-01

    The ruins of San Bartolo, Guatemala, contain a sample of Maya hieroglyphic writing dating to the Late Preclassic period (400 B.C. to 200 A.D.). The writing appears on preserved painted walls and plaster fragments buried within the pyramidal structure known as "Las Pinturas," which was constructed in discrete phases over several centuries. Samples of carbonized wood that are closely associated with the writing have calibrated radiocarbon dates of 200 to 300 B.C. This early Maya writing implies that a developed Maya writing system was in use centuries earlier than previously thought, approximating a time when we see the earliest scripts elsewhere in Mesoamerica.

    Nous utilisons un Oscillateur Paramétrique Optique (OPO) pompé sous le seuil dans le but d'amplifier une image multimode transverse sans dégradation du rapport signal à bruit. Le dispositif expérimental met en œuvre un OPO de type II triplement résonant et semi-confocal pour le faisceau amplifié. L'existence d'effets quantiques lors de l'amplification multimode dans un tel dispositif a été montrée expérimentalement. Plus généralement, ceci nous a amené à étudier les propriétés quantiques transverses des faisceaux lumineux amplifiés. Une telle étude peut trouver des applications non seulement en imagerie, mais également dans le traitement quantique de l'information.

    San Nicolas Island (SNI) is the site of the Navy Range Instrumentation Test Site which relies on an isolated diesel-powered grid for its energy needs. The island is located in the Pacific Ocean 85 miles southwest of Los Angeles, California and 65 miles south of the Naval Air Weapons Station (NAWS), Point Mugu, California. SNI is situated on the continental shelf at latitude N33{degree}14` and longitude W119{degree}27`. It is approximately 9 miles long and 3.6 miles wide and encompasses an area of 13,370 acres of land owned by the Navy in fee title. Winds on San Nicolas are prevailingly northwest and are strong most of the year. The average wind speed is 7.2 m/s (14 knots) and seasonal variation is small. The windiest months, March through July, have wind speeds averaging 8.2 m/s (16 knots). The least windy months, August through February, have wind speeds averaging 6.2 m/s (12 knots).

  14. The radiological accident in San Salvador

    International Nuclear Information System (INIS)

    On 5 February 1989, a radiological accident occurred at an industrial irradiation facility near San Salvador, the capital of the Republic of El Salvador. Prepackaged medical products are sterilized at the facility by irradiation by means of an intensely radioactive cobalt-60 source in a movable source rack. The accident happened when this source rack became stuck in the irradiation position. The operator bypassed the irradiator's already degraded safety systems and entered the radiation room with two other workers to free the source rack manually. The three workers were exposed to high radiation doses and developed the acute radiation syndrome. Their initial hospital treatment in San Salvador and subsequent more specialized treatment in Mexico City were effective in countering the acute effects. However, the legs and feet of two of the three men were so seriously injured that amputation was required. The worker who had been most exposed died six and a half months after the accident, his death being attributed to residual lung damage due to irradiation, exacerbated by injury sustained during treatment. The report details the events leading up to the accident, the circumstances of the accident itself and the response to it. From the facts established, lessons are derived for operators and suppliers of irradiators, national authorities, medical staff and international organizations. Detailed information on dosimetric and medical aspects of the accident for the specialist reader is presented in the appendices and annexes. 20 figs, 9 tabs, 24 photographs

    Two well-equilibrated Na-Cl geothermal liquids are recognisable in the San Marcos area. Both have the same Cl concentration (540 mg/kg) and the same isotopic composition ({delta}D of -66.5 per mille and {delta}{sup 18}O of -9 per mille) under reservoir conditions, but they come from two distinct aquifers with different temperatures , i.e. 240degC below La Cimarrona and 185degC below La Castalia. The numerous thermal Na-Cl to Na-Cl-HCO{sub 3} springs located in the San Marcos areas originate through dilution and boiling of these two geothermal liquids and different degrees of re-equilibration at lower temperatures. Silica and K contents are useful in discriminating between dilution, boiling and re-equilibration phenomena. Thermal Na-HCO{sub 3} waters, generated through conductive heat transfer or input of geothermal vapor or gases from below, delineate the extent of the geothermal reservoir(s) at depth. (Author)

  16. Il Maestro della Commenda di Meldola e la magione ospitaliera di San Giovanni Battista

    Directory of Open Access Journals (Sweden)

    Paolo Cova

    2012-02-01

    Full Text Available L’intervento propone, attraverso l’indagine di alcuni dipinti di area forlivese, una prima ricostruzione della personalità di un interessante interprete locale del XV secolo, provvisoriamente denominato Maestro della Commenda di Meldola. Lo studio, parte integrante della mia tesi di dottorato, prende le mosse dall’analisi dell’affresco dell’Oratorio di San Giovanni Battista a Meldola, per poi allargarsi ad altre emergenze del territorio circostante, fino ai lacerti pittorici emersi nella chiesa della Santissima Trinità di Forlì. Nella prima parte dell’articolo viene ricostruita la storia dell’Oratorio di San Giovanni Battista presso Villa Fronticelli a Meldola: già magione templare di Santa Maria Biacque, nel 1312, in seguito al processo ai templari, passò alle dipendenze della precettoria dei cavalieri gerosolimitani di San Giovanni di Palareto. La realizzazione dell’affresco deve essere probabilmente inserita all’interno dei lavori di ristrutturazione intrapresi dai giovanniti dopo la metà del XV secolo. Nella seconda parte dell’articolo invece si procede alle indagini tecniche e stilistiche relative alla pittura murale che rappresenta la Madonna col Bambino e San Giovanni Battista. L’affresco mutilo è opera di un interessante maestro che agisce nella sfera del tardogotico locale, mostrando però tenui accenti rinascimentali caratteristici alla pittura forlivese tra sesto e settimo decennio del Quattrocento. Muovendo dalle ricerche di Anna Tambini e Giordani Viroli, attraverso l’analisi di diverse testimonianze del territorio, viene così proposta la ricostruzione di un corpus pittorico caratterizzato da stringenti affinità stilistiche, che, confermando l’appartenenza del suo anonimo pittore ad un milieu stilistico caro ad altri interpreti forlivesi del periodo, come il Maestro di Castrocaro o il Maestro di San Pier Damiani, aiuta ulteriormente a chiarire il panorama artistico romagnolo all’avvento della 'brigada melozziana'.

  8. Risk behaviors for HIV in sexual partnerships of San Francisco injection drug users.

    Science.gov (United States)

    Chen, Yea-Hung; McFarland, Willi; Raymond, Henry Fisher

    2014-01-01

    While injection drug users (IDU) in the USA are known to form sexual partnerships with IDU as well as non-IDU, scientific research is lacking regarding risk behaviors for HIV transmission within these partnerships. Such information could aid HIV-prevention efforts among IDU and could also explain the relatively low prevalence of HIV among non-IDU heterosexuals in US cities such as San Francisco. Using data from a cross-sectional sample of San Francisco IDU we estimated (1) the prevalence of IDU-IDU and IDU-non-IDU sexual partnerships, (2) the frequency of serodiscordant unprotected intercourse in IDU-IDU and IDU-non-IDU sexual partnerships, and (3) the frequency of concurrence of sexual risk and injection-related risk within IDU-IDU sexual partnerships. An estimated 68% of sexually active San Francisco IDU is in IDU-IDU partnerships. Our analysis suggests that compared to IDU-non-IDU partnerships, IDU-IDU partnerships include a greater rate of episodes of serodiscordant unprotected intercourse (incidence rate ratio: 10.2; 95% confidence interval: 2.1-50.7). In fact, our data suggest that 92% of serodiscordant sexual episodes involving IDU are attributable to IDU-IDU pairings. Unprotected intercourse and needle sharing occur concurrently in an estimated 29% of IDU-IDU partnerships. Our data suggest that HIV-transmission risk is higher within IDU-IDU partnerships than it is within IDU-non-IDU partnerships. This disparity could explain the relatively low prevalence of HIV among non-IDU heterosexuals in San Francisco. We recommend that HIV-prevention efforts among IDU continue to address sexual risk behaviors for HIV transmission in addition to injection-related risk behaviors, with emphasis on IDU-IDU partnerships.

  14. Microbial biogeography of San Francisco Bay sediments

    Science.gov (United States)

    Lee, J. A.; Francis, C. A.

    2014-12-01

    The largest estuary on the west coast of North America, San Francisco Bay is an ecosystem of enormous biodiversity, and also enormous human impact. The benthos has experienced dredging, occupation by invasive species, and over a century of sediment input as a result of hydraulic mining. Although the Bay's great cultural and ecological importance has inspired numerous surveys of the benthic macrofauna, to date there has been almost no investigation of the microbial communities on the Bay floor. An understanding of those microbial communities would contribute significantly to our understanding of both the biogeochemical processes (which are driven by the microbiota) and the physical processes (which contribute to microbial distributions) in the Bay. Here, we present the first broad survey of bacterial and archaeal taxa in the sediments of the San Francisco Bay. We conducted 16S rRNA community sequencing of bacteria and archaea in sediment samples taken bimonthly for one year, from five sites spanning the salinity gradient between Suisun and Central Bay, in order to capture the effect of both spatial and temporal environmental variation on microbial diversity. From the same samples we also conducted deep sequencing of a nitrogen-cycling functional gene, nirS, allowing an assessment of evolutionary diversity at a much finer taxonomic scale within an important and widespread functional group of bacteria. We paired these sequencing projects with extensive geochemical metadata as well as information about macrofaunal distribution. Our data reveal a diversity of distinct biogeographical patterns among different taxa: clades ubiquitous across sites; clades that respond to measurable environmental drivers; and clades that show geographical site-specificity. These community datasets allow us to test the hypothesis that salinity is a major driver of both overall microbial community structure and community structure of the denitrifying bacteria specifically; and to assess whether patterns of diversity observed at the broadest of taxonomic scales also apply to patterns observed within a single extremely diverse gene (nirS). In sum, this project provides a first look at the forces driving the migration and selection of microbial communities in San Francisco Bay.

The University of Minnesota participants were asked to verify that the performance of the SAN/CXFS configuration did not fall below 85% of the performance of the XFS local configuration. There were two basic hardware test configurations constructed from the following equipment: Two Onyx 2 computer systems each with two Qlogic-based Fibre Channel/XIO Host Bus Adapter (HBA); One 8-Port Brocade Silkworm 2400 Fibre Channel Switch; and Four Ciprico RF7000 RAID Disk Arrays populated Seagate Barracuda 50GB disk drives. The Operating System on each of the ONYX 2 computer systems was IRIX 6.5.6. The first hardware configuration consisted of directly connecting the Ciprico arrays to the Qlogic controllers without the Brocade switch. The purpose for this configuration was to establish baseline performance data on the Qlogic controllers / Ciprico disk raw subsystem. This baseline performance data would then be used to demonstrate any performance differences arising from the addition of the Brocade Fibre Channel Switch. Furthermore, the performance of the Qlogic controllers could be compared to that of the older, Adaptec-based XIO dual-channel Fibre Channel adapters previously used on these systems. It should be noted that only raw device tests were performed on this configuration. No file system testing was performed on this configuration. The second hardware configuration introduced the Brocade Fibre Channel Switch. Two FC ports from each of the ONYX2 computer systems were attached to four ports of the switch and the four Ciprico arrays were attached to the remaining four. Raw disk subsystem tests were performed on the SAN configuration in order to demonstrate the performance differences between the direct-connect and the switched configurations. After this testing was completed, the Ciprico arrays were formatted with an XFS file system and performance numbers were gathered to establish a File System Performance Baseline. Finally, the disks were formatted with CXFS and further tests were run to demonstrate the performance of the CXFS file system. A summary of the results of these tests is given.

  17. SANS and dynamic light scattering to investigate the viscosity of toluene under high pressure up to 1800 bar

    International Nuclear Information System (INIS)

    We present a joint experimental study of small angle neutron scattering (SANS) and dynamic light scattering (DLS) under high pressures up to 1800 bar on a colloidal suspension, which consists of a core–shell system made of sterically stabilized silica particles grafted with octadecyl chains in toluene. From the analysis of SANS contrast variation under pressure, we could estimate the amount of compression in both core and shell under the action of pressure. The DLS measurements under pressure yield a diffusion coefficient which enabled us together with the SANS result to evaluate the pressure-dependent viscosity of the dilute suspension which is to a good approximation the solvent viscosity on the basis of the Stokes–Einstein relation. The excellent comparison of the so-calculated pressure-dependent viscosities of toluene with literature values demonstrates the value of our method to measure viscosities under pressure

    International Nuclear Information System (INIS)

    An airborne radiological survey of an 11 km2 area surrounding the San Onofre Nuclear Generating Station was made 9 to 17 January 1980. Count rates observed at 60 m altitude were converted to exposure rates at 1 m above the ground and are presented in the form of an isopleth map. Detected radioisotopes and their associated gamma ray exposure rates were consistent with that expected from normal background emitters, except directly over the plant

    Full Text Available El plutón La Florida se localiza en la parte central de la Sierra de San Luis y se aloja en metasedimentitas regionales de grado medio pertenecientes al grupo micaesquistos derivadas de subgrauvacas y areniscas. Es de morfología semicircular, ligeramente elongado en dirección oblicua a la foliación [...] regional, la cual acompaña la forma del plutón en el contacto. Su composición es monzogranítica y marcadamente peraluminoso, y está compuesto por cuarzo, microclino, plagioclasa, muscovita, biotita y granate. El estudio detallado ha permitido establecer que el contenido de biotita de los monzogranitos disminuye hacia los bordes del cuerpo en tanto que la muscovita, generalmente porfiroblástica, aumenta, lo cual conduce a variaciones notables del índice de color de las rocas. Además, se registra una abundante pegmatización que forma tanto diques como cuerpos irregulares en el borde del intrusivo y también en las rocas de caja adyacentes al contacto. Esta zonación sería resultado del incremento de fluidos acuosos durante la etapa tardío magmática, que causaron reacciones subsólidas en la mineralogía ortomagmática. El magma está relacionado con el proceso subductivo desarrollado durante la orogenia famatiniana, muestra afinidad con fundidos sin-colisionales y un tren evolutivo compatible con magmas de tipo S. El plutón de La Florida exhibe algunas diferencias geológicas, petrográficas y composionales con otros granitoides sin-cinemáticos de la sierra de San Luis, encontrándose algunas similitudes solamente con rocas del cordón de El Realito. Abstract in english La Florida pluton is located in the central part of the Sierra de San Luis. It is a nearly semicircular-shape intrusion, slightly elongated perpendicularly to the main NNE-SSW country rocks foliation, which deforms at the pluton margins. The body is emplaced in medium-grade metamorphosed subgreywake [...] s and sandstones-derived rocks of the Micaschist Group. Intrusive rocks are mostly greyish medium to coarse-grained peraluminous monzogranites, composed of quartz, microcline, plagioclase, muscovite, biotite and minor garnet. Biotite content decreases from the core to the margin of the pluton while muscovite, usually forming up to 4 cm-long porphyroblasts, and garnet amounts increase in such direction. This leads to a remarkable variation of the colour index across the body, grading from 12 % to 0 % at the contact with the country rocks. Abundants dykes and irregular bodies of pegmatites intrude the outer parts of the pluton as well as the adjacent metasedimentary country rocks. The mineralogical zonation and the increase of pegmatization to the margins is interpreted here as the result of the enrichment in water-rich late-magmatic fluids which caused subsolid reactions with the minerals cristallized during the orthomagmatic stage. The magmatism is related to the Famatinian subduction, showing a syn-collisional affinity and S-type evolutionary trend. However, several differences have been found between La Florida and others syn-kinematic S-type granitoids from the Sierra de San Luis.

En el departamentoSan Martín hay tres grupos mineros: Los Avestruces, La Aspereza y CerritoBlanco. La geología del área está constituida por rocas del ComplejoMetamórfico Conlara, compuesto por esquistos cuarzo-m [...] icáceos de rumboaproximado N300º y por granitoides y pegmatitas. Además, hay lamprófiroscalcoalcalinos sobresaturados que conforman cuerpos subverticales de rumboNO-SE a O-E. Hacia la salbanda se incrementa la cantidad de biotita hasta un80-90% constituyendo una roca denominada biotitita que sería producto deprocesos metasomáticos y posterior cataclasis del lamprófiro.

La deformación de la fase achaliana y la intrusión del batolito LasChacras-Piedras Coloradas (Devónico a Carbonífero) son los eventos quepromovieron la removilización de fluidos de los sedimentos del basamento, sucanalización en fracturas, y el metasomatismo y la mineralización. Abstract in english Towards thenortheast of the Sierra de San Luis several wolfram ore deposits occur. In SanMartín district they are divided into three groups: Los Avestruces, LaEsperanza and Cerrito Blanco. The geology of this area is formed of the Conlarametamorphic complex composed of schists (with a strike of 300º [...] north),granitoids and pegmatites. In the same area subsaturated chalco-alkalinelamprophyres also appear as subvertical bodies with NW-NE strikes. Toward theboundaries of these rocks, the amount of biotite rises gradually from 80 to 90%developing a biotitite rock due to metasomatic processes and the superimposeddeformation. This biotitite is rich in K, Rb and W among other elements. Thescheelite mineralization (with quartz, biotite and tourmaline as non oreminerals) occurs in veins that are usually hosted between the lamprophyres andthe wall rocks. Scheelite also appears between the schist planes of thebiotitite rocks as well as disseminated crystals in quartz aggregates. Thismineralization took place from fluids with XH2O: 0.87/0.82 - XCO2:0.11/0.16 - XNaCl: 0.015/0.013 - (CH4) meanwhile the scheelite,according to the fluid inclusions studies, precipitated from unmixing processesbelow 320°C and 2.3 kb. Achaliana orogeny and the intrusion of LasChacras-Piedras Coloradas batholiths (Devonian-Carboniferous) were theresponsible for the slight rise of the fluids from the basement, the generationof fault structures through which they rose, the metasomatism and themineralization.

  1. San Andreas Fault in the Carrizo Plain

    Science.gov (United States)

    2000-01-01

    The 1,200-kilometer (800-mile)San Andreas is the longest fault in California and one of the longest in North America. This perspective view of a portion of the fault was generated using data from the Shuttle Radar Topography Mission (SRTM), which flew on NASA's Space Shuttle last February, and an enhanced, true-color Landsat satellite image. The view shown looks southeast along the San Andreas where it cuts along the base of the mountains in the Temblor Range near Bakersfield. The fault is the distinctively linear feature to the right of the mountains. To the left of the range is a portion of the agriculturally rich San Joaquin Valley. In the background is the snow-capped peak of Mt. Pinos at an elevation of 2,692 meters (8,831 feet). The complex topography in the area is some of the most spectacular along the course of the fault. To the right of the fault is the famous Carrizo Plain. Dry conditions on the plain have helped preserve the surface trace of the fault, which is scrutinized by both amateur and professional geologists. In 1857, one of the largest earthquakes ever recorded in the United States occurred just north of the Carrizo Plain. With an estimated magnitude of 8.0, the quake severely shook buildings in Los Angeles, caused significant surface rupture along a 350-kilometer (220-mile) segment of the fault, and was felt as far away as Las Vegas, Nev. This portion of the San Andreas is an important area of study for seismologists. For visualization purposes, topographic heights displayed in this image are exaggerated two times.The elevation data used in this image was acquired by SRTM aboard the Space Shuttle Endeavour, launched on February 11, 2000. SRTM used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994. SRTM was designed to collect three-dimensional measurements of Earth's land surface. To collect the 3-D SRTM data, engineers added a mast 60 meters (about 200 feet) long, installed additional C-band and X-band antennas, and improved tracking and navigation devices. The mission is a cooperative project between the NASA, the National Imagery and Mapping Agency (NIMA) of the U.S. Department of Defense, and the German and Italian space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif, for NASA's Earth Science Enterprise, Washington, D.C.

    Full Text Available En este artículo se mide el cambio en la productividad durante la década de los años noventa en San Mateo Atenco para un grupo de empresas, descomponiendo a su vez dicho cambio en uno tecnológico, cambio en eficiencia y en escala. A pesar de que el aumento en la productividad fue de sólo 1.2% para los empresarios cuyas empresas fueron evaluadas, la productividad nunca apareció como un factor a considerar a fin de asegurar su permanencia en el mercado. Esto es trascendente ya que esta percepción desincentiva el uso de los apoyos que brindan los programas gubernamentales. Lo anterior sugiere que, el reto de las políticas públicas es conseguir que las empresas encuentren en la productividad el mejor aliado para aumentar su rentabilidad.

    Isla San Cristobal, the most easterly of the Galapagos Islands, consists of two parts: a large volcano constitutes the southwest half of the island and an irregular apron of small cones and flows makes up the northeast half. As some of the younger flows on the flanks of the large volcano are reversely magnetized, the minimum age of the volcano is 0.7 my, which is the age of the Brunhes-Matuyama reversal boundary. The true age is probably several times greater. The cones and flows to the northeast are all normally magnetized. The between-site angular dispersion of virtual poles is 11.3?? - a value consistent with mathematical models for the latitude dependence of geomagnetic secular variation. ?? 1971.

    Full Text Available Baptized but once - Sans Jamais Le Réitérer In principle re-baptism is rejected by almost all churches and theologians. However, since some regard infant baptism as invalid, they encourage those who have not been baptized in faith and obedience to have it administered by immersion. On the contrary, it is argued that, no matter what circumstances prevailed, any baptism administered with water in the ‘Name of the Father and of the Son and of the Holy Spirit’ by a church official with the power to baptize is indeed valid and should never be repeated. Neither do baptism of confirmation or ‘double baptism’ offer a solution. At the root of the problem a difference of approach towards the covenant of grace is maintained. Churches maintaining the infant baptism tradition should, however, critically view the praxis of their doctrine and consider whether church members are perhaps too readily allowed to present their children for baptism.

    Full Text Available En esta investigación se evalúa una hipótesis que sostiene que en las comunidades rurales la reciente migración internacional ha inducido una mayor desigualdad en la distribución del ingreso (Stark, Taylor y Yitzhaki, 1986. Para analizar el efecto de las remesas internacionales sobre la distribución del ingreso en una muestra de 37% de los hogares en San Miguel Coatlán, Oaxaca, se ha utilizado la descomposición del coeficiente de Gini por fuentes de ingreso. Los resultados muestran que si bien en esta comunidad se advierte una fuerte desigualdad, las remesas mejoran la distribución; la historia migratoria no decide la forma de la distribución, sino que depende más bien de la estructura de los hogares que perciben las remesas, de la importancia de éstas respecto a los demás ingresos, y de ciertas formas culturales que propician la incorporación a la migración de algunos miembros de hogares de todos los estratos económicos de la comunidad.

    2007-11-15

    CLIC is one of the current projects of high energy linear colliders. Vertical beam sizes of 0.7 nm at the time of the collision and fast ground motion of a few nanometers impose an active stabilization of the final doublets at a fifth of nanometer above 4 Hz. The majority of my work concerned vibrations and active stabilization study of cantilever and slim beams in order to be representative of the final doublets of CLIC. In a first part, measured performances of different types of vibration sensors associated to an appropriate instrumentation showed that accurate measurements of ground motion are possible from 0.1 Hz up to 2000 Hz on a quiet site. Also, electrochemical sensors answering a priori the specifications of CLIC can be incorporated in the active stabilization at a fifth of nanometer. In a second part, an experimental and numerical study of beam vibrations enabled to validate the efficiency of the numerical prediction incorporated then in the simulation of the active stabilization. Also, a study of the impact of ground motion and of acoustic noise on beam vibrations showed that an active stabilization is necessary at least up to 1000 Hz. In a third part, results on the active stabilization of a beam at its two first resonances are shown down to amplitudes of a tenth of nanometer above 4 Hz by using in parallel a commercial system performing passive and active stabilization of the clamping. The last part is related to a study of a support for the final doublets of a linear collider prototype in phase of finalization, the ATF2 prototype. This work showed that relative motion between this support and the ground is below imposed tolerances (6 nm above 0.1 Hz) with appropriate boundary conditions. (author)

  15. The wister mud pot lineament: Southeastward extension or abandoned strand of the San Andreas fault?

    Lynch, D.K.; Hudnut, K.W.

    2008-01-01

    We present the results of a survey of mud pots in the Wister Unit of the Imperial Wildlife Area. Thirty-three mud pots, pot clusters, or related geothermal vents (hundreds of pots in all) were identified, and most were found to cluster along a northwest-trending line that is more or less coincident with the postulated Sand Hills fault. An extrapolation of the trace of the San Andreas fault southeastward from its accepted terminus north of Bombay Beach very nearly coincides with the mud pot lineament and may represent a surface manifestation of the San Andreas fault southeast of the Salton Sea. Additionally, a recent survey of vents near Mullet Island in the Salton Sea revealed eight areas along a northwest-striking line where gas was bubbling up through the water and in two cases hot mud and water were being violently ejected.

  16. SANS investigation of microstructure evolution in high chromium ODS steels after thermal ageing

    Száraz, Z.; Török, Gy.; Kršjak, V.; Hähner, P.

    2013-04-01

    In the present paper the small-angle neutron scattering (SANS) technique was used to investigate the phase separation in two oxide dispersion strengthened (ODS) ferritic steels, PM2000 and MA956, during isothermal ageing at 475 °C. The ferritic matrix of the investigated materials separates into Fe-rich ? and Cr-rich ?' phases during ageing at this temperature. The samples were measured under magnetic field in order to separate the nuclear and magnetic scattering intensities. The ratio of these two contributions was used to gain information on the chemical composition of the scatterers. The SANS measurements revealed the formation and subsequent growth of Cr-rich precipitates on the nanometer scale. The size distributions and the volume fractions of the precipitates were evaluated from the scattering data. Microhardness was found to significantly increase as a function of ageing time for both materials. The hardening is related to the formation of the Cr-rich ?' phase.

  17. A correlation for miscible flood displacement efficiency in the San Andres with NMR relaxation

    International Nuclear Information System (INIS)

    This paper reports that a set of San Andres crystalline dolomite cores was examined for the relationship between pore attributes discernible from NMR relaxation and miscible flooding displacement efficiency. A strong correlation was observed between the inferred abundance of long relaxation time components and laboratory measured residual oil to a multicontact miscible displacement process. NMR relaxation time distribution proved to be a simple, noninvasive, nondestructive indicator of flow performance in the 12 San Andres dolomite samples examined. Spin-lattice relaxation measurements were conducted on clean, brine saturated core end pieces from plugs taken adjacent to those used for flow displacement studies. Sample data were deconvoluted into a distribution of relaxation times, which is ultimately related to surface-to-volume ratio distribution. The median relaxation time was determined to be the most sensitive statistics to convey flow performance. Residual oil saturation was adequately represented by a power law function of the median relaxation time

    During September 1979, the breakdown of a waste treatment plant resulted in discharge of 1.5 X 107 m3 of primary- treated sewage into a tributary of South San Francisco Bay. Chemical and microbial changes occurred within the tributary as decomposition and nitrification depleted dissolved oxygen. Associated with anoxia were relatively high concentrations of particulate organic carbon, dissolved CO2, CH4, C2H4, NH4+, and fecal bacteria, and low phytoplankton biomass and photosynthetic oxygen production. South San Francisco Bay experienced only small changes in water quality, presumably because of its large volume and the assimilation of wastes that occurred within the tributary. Water quality improved rapidly in the tributary once normal tertiary treatment resumed. -Authors

    This thesis concerns the mathematical and numerical study of nonlinear hyperbolic partial differential equations. A first part deals with an emergent problematic: the coupling of hyperbolic equations. The pursued applications are linked with the mathematical coupling of computing platforms, dedicated to an adaptative simulation of multi-scale phenomena. We propose and analyze a new coupling formalism based on extended PDE systems avoiding the geometric treatment of the interfaces. In addition, it allows to formulate the problem in a multidimensional setting, with possible covering of the coupled models. This formalism allows in particular to equip the coupling procedure with viscous regularization mechanisms, useful in the selection of natural discontinuous solutions. We analyze existence and uniqueness in the framework of a parabolic regularization a la Dafermos. Existence of a solution holds true under very general conditions but failure of uniqueness may naturally arise as soon as resonance occurs at the interfaces. Next, we highlight that our extended PDE framework gives rise to another regularization strategy based on thick interfaces. In this setting, we prove existence and uniqueness of the solutions of the Cauchy problem for initial data in L{sup {infinity}}. The main tool consists in the derivation of a flexible and robust finite volume method for general triangulation which is analyzed in the setting of entropy measure-valued solutions by DiPerna. The second part is devoted to the definition of a finite volume scheme for the computing of nonclassical solutions of a scalar conservation law based on a kinetic relation. This scheme offers the feature to be stricto sensu conservative, in opposition to a Glimm approach that is only statistically conservative. The validity of our approach is illustrated through numerical examples. (author)

    Full Text Available Las rocas metamórficas aflorantes en la Plancha 64 (estribación NE de la Serranía de San Lucas, Cordillera Central), están agrupadas en dos unidades estratigráficas: una denominada formación Neis de San Lucas y otra unidad de carácter informal, denominada Unidad Metamórfica de Pinillos. Esta ultima, [...] compuesta por los Esquistos de Armenia y las Filitas de Tapoa. El Neis de San Lucas, consiste en neises cuarzo-feldespáticos (neises cuarzo-feldespáticos con biotita, neises cuarzo-feldespáticos con hornblenda) y rocas metamáficas (neis hornblendico, granulitas, metagabros). Los Esquistos de Armenia, se componen de esquistos pelíticos, tales como esquistos micáceos y esquistos micáceos con andalusita, y esquistos calco-silicatados, los cuales son cuarzosos con cantidades variables de minerales del grupo de la epidota, hornblenda y actinolita. Las Filitas de Tapoa son rocas compuestas de cuarzo y sericita con minerales opacos alterados. El metamorfismo del Neis de San Lucas es regional, alcanzando las facies anfibolita alta y granulita piroxénica. Edades U-Pb en circones de esta formación, apunta a un evento tectonotermal del Mesoproterozoico (1124Ma±22 Ma), relacionado con la orogenia Grenviliana, durante la consolidación del supercontinente Rodinia. Las rocas de la Unidad Metamórfica de Pinillos, es considerada por sus relaciones de campo, como de edad Paleozoica Temprano. Abstract in english The metamorphic rocks that outcrop in the San Lucas foothills (in the area covered by the map indentifed as number 64), are grouped in two stratigraphic units: The so-called San Lucas Gneiss Formation and the Pinillos Metamorphic Unit (informal stratigraphic denomination). This latter unit is compos [...] ed by The Armenia Schists and Tapoa Phyllites. The San Lucas Gneiss Formation, comprise quartz-feldspar gneisses (quartz-feldspar gneisses with biotite, quartz-feldspar gneisses with hornblende) and metamafc rocks (hornblende gneiss, granulites and metagabbros). The Armenia Schists is composed by pelite schists; such as micaceous schists; micáceous schists with andalusite; and calco-silicate schists, quartz rich and with variable amounts of minerals from epidote, hornblende and actinolite groups. The Tapoa Phyllite Rocks are composed by quartz and sericite with altered opaque minerals. The San Lucas Gneiss Formation Metamorphism is regional and reaches the high anfbolite and pyroxene granulites facies. The 1.124Ma ± 22 zircon U-Pb age, indicates a Mesoproterozoic tectonothermal event, related to the Grenville Orogeny, that took place during the Rodinia supercontinent consolidation. The Pinillos Metamorphic Rocks Unit, is Early Paleozoic in age, according to the feld relations.

  3. Danger on mountain roads, Iglesia Department, San Juan, Argentina

    International Nuclear Information System (INIS)

    This paper is related to Mining Projects at Valle del Cura - Iglesia Department-San Juan Province-Argentina Republic. Basis for an Integrated Management of a Sustainable Mining.It aims at locating and analyzing natural dangers which may interfere high mountain paths, such as climatic, anthropic and/or tectonic factors since they may stop a region development. A hillside, a mountainside,a talus or a slope may have, due to their extensive areas, either lithological or structural variations which might determine the presence of un stability phenomena.The cordillera n Iglesia sector major dangers are related to mass displacement movements as a result of the great quantity of unstable detritus situated in valleys slopes.Landsat images, aerial photographs, topographic and geological maps data allowed to detect several sectors that may generate mass displacement movements, Arroyo de Aguas Negras rising sector was selected because it is on the right of National Route No. 150 trace. It is not only a national, but also an international route that connects Argentina and Chile.(author)

    San Juan County, in the northwestern corner of New Mexico, uses surface water from the San Juan, Animas, and La Plata Rivers as a principal source of water for the county, but the water in these streams is fully appropriated. Ground water is present in San Juan County in several bedrock formations and in the alluvium of the river valleys. This report describes the hydrologic data that have been collected in San Juan County, presents examples of the data, shows the locations of the data-collection sites, and indicates where more complete records may be obtained. This data base should be helpful in assessing the quantity, quality, and availability of the county 's water resources.

  5. Microstructure of magnetite doped elastomers investigated by SAXS and SANS

    International Nuclear Information System (INIS)

    Some recent results on the SAXS and SANS investigations of the magnetic elastomers are presented. Samples were obtained by polymerizing dimethylsiloxane with Fe3O4 ferrofluid in a magnetic field and without magnetic field and characterized by XRD, SANS and SAXS. The SAXS maximum at large angles, obtained from magnetic elastomers, was fitted by using a Pseudo-Voigt function. It was found that the Fe3O4 particles lead to a change of the local structure of the elastomer, meaning the decrease of the quasi-crystalline phase and of the microstrains induced in the matrix. The average particle size obtained from SANS measurements agrees well with the average particle size determined by XRD and SAXS analysis. The splitting of the SANS intensity owing to an additional scattering in zero field reflects the existence of magnetic correlations inside the Q region of 0.005 -1

    Full Text Available The state of Baja California has the greatest municipalities of the country and, therefore, the fewest. New municipalities have begun to be formed recently: Playas de Rosarito in 1995 and, as projects, San Quintín and San Felipe. Traditionally, a municipality is designed according to socioeconomic and, mainly, political reasons. Our proposal puts the ecosistemic unit of a hydrographic basin on a level with a political-administrative unit, that in this case would be the municipality. Today, municipalities make use of hydrographic basins and their natural resources in an ecologically disintegrated fashion. The creation of a new municipality is proposed, that would cover three delegations whose area corresponds to the hydrographic basins of the Sierra de San Pedro Mártir flowing into the Pacific and feeding the agriculture valley of San Quintín. This proposal coincides with today?s agenda of municipal reform

  10. A record of hydrocarbon input to San Francisco Bay as traced by biomarker profiles in surface sediment and sediment cores

    Science.gov (United States)

    Hostettler, F.D.; Pereira, W.E.; Kvenvolden, K.A.; VanGeen, A.; Luoma, S.N.; Fuller, C.C.; Anima, R.

    San Francisco Bay is one of the world's largest urbanized estuarine systems. Its water and sediment receive organic input from a wide variety of sources; much of this organic material is anthropogenically derived. To document the spatial and historical record of the organic contaminant input, surficial sediment from 17 sites throughout San Francisco Bay and sediment cores from two locations Richardson Bay and San Pablo Bay were analyzed for biomarker constituents. Biomarkers, that is, 'molecular fossils', primarily hopanes, steranes, and n-alkanes, provide information on anthropogenic contamination, especially that related to petrogenic sources, as well as on recent input of biogenic material. The biomarker parameters from the surficial sediment and the upper horizons of the cores show a dominance of anthropogenic input, whereas the biomarker profiles at the lower horizons of the cores indicate primarily biogenic input. In the Richardson Bay core the gradual upcore transition from lower maturity background organics to a dominance of anthropogenic contamination occurred about 70-100 years ago and corresponds to the industrial development of the San Francisco Bay area. In San Pablo Bay, the transition was very abrupt, reflecting the complex depositional history of the area. This sharp transition, perhaps indicating a depositional hiatus or erosional period, dated at pre-1952, is clearly visible. Below, the hiatus the biomarker parameters are immature; above, they are mature and show an anthropogenic overlay. Higher concentrations of terrigenous n-alkanes in the upper horizons in this core are indicative of an increase in terrigenous organic matter input in San Pablo Bay, possibly a result of water diversion projects and changes in the fresh water flow into the Bay from the Delta. Alternatively, it could reflect a dilution of organic material in the lower core sections with hydraulic mining debris.

    Full Text Available The 50,470 m2 the total area of the hospital is distributed as follows: 18,900 m2 for the 22 main clinics and for the additional clinics; 2,770 m2 for complementary activities; and the remaining 28,800 m2 for a parking lot with space for 700 cars. The building occupies a site that slopes strongly towards the north across which runs the pedestrian access from one of the circumference roads to the main façade; the access road for the vehicles leads to the back facade, where the natural slope of the ground has been taken advantage of to build the 5 storey parking building. The two main functions —the clinics and the parking house— are conveniently separated though connected with each other by means of corridors and lifts. The interior design of the clinics is very flexible so as to allow for further enlargements. The patients' waiting rooms are provided with a glazed façade and have a beautiful view over the San Francisco Bay and its surroundings. The construction is entirely of concrete and its structure is calculated ín such a manner as to allow for two additional storeys.Cuenta con una superficie total construida de 50.470 m2, repartidos de la siguiente forma: 18.900 se destinan a la distribución de 22 clínicas principales y otras secundarias; 2.770 a locales de actividades complementarias; y el resto, 28.800 m2, a aparcamiento con capacidad para 700 plazas. El edificio ocupa una parcela fuertemente inclinada hacia el norte, inclinación que permite el acceso peatonal a la clínica, por la fachada principal, desde una de las avenidas perimetrales; y el vehicular, por la fachada posterior, en donde, aprovechando el desnivel del terreno, se han organizado las cinco plantas del aparcamiento. Las dos funciones principales —clínicas y aparcamiento— se hallan convenientemente separadas, estableciéndose el enlace entre los distintos niveles mediante ascensores que relacionan las clínicas, el centro médico, los aparcamientos y las calles exteriores. A su vez, el área de las clínicas está servida por un grupo central de ascensores. El espacio interior reservado a las clínicas es altamente flexible, con el fin de posibilitar futuras modificaciones. Las salas de espera para los pacientes se localizan en el perímetro acristalado, dominando un amplio panorama de la bahía de San Francisco y de las zonas circundantes. La construcción se ha realizado en su totalidad de hormigón, con estructura calculada para la eventual incorporación de dos nuevas plantas.

  18. Sediment transport in the San Francisco Bay Coastal System: an overview

    Barnard, Patrick L.; Schoellhamer, David H.; Jaffe, Bruce E.; McKee, Lester J.

    2013-01-01

    The papers in this special issue feature state-of-the-art approaches to understanding the physical processes related to sediment transport and geomorphology of complex coastal–estuarine systems. Here we focus on the San Francisco Bay Coastal System, extending from the lower San Joaquin–Sacramento Delta, through the Bay, and along the adjacent outer Pacific Coast. San Francisco Bay is an urbanized estuary that is impacted by numerous anthropogenic activities common to many large estuaries, including a mining legacy, channel dredging, aggregate mining, reservoirs, freshwater diversion, watershed modifications, urban run-off, ship traffic, exotic species introductions, land reclamation, and wetland restoration. The Golden Gate strait is the sole inlet connecting the Bay to the Pacific Ocean, and serves as the conduit for a tidal flow of ~ 8 × 109 m3/day, in addition to the transport of mud, sand, biogenic material, nutrients, and pollutants. Despite this physical, biological and chemical connection, resource management and prior research have often treated the Delta, Bay and adjacent ocean as separate entities, compartmentalized by artificial geographic or political boundaries. The body of work herein presents a comprehensive analysis of system-wide behavior, extending a rich heritage of sediment transport research that dates back to the groundbreaking hydraulic mining-impact research of G.K. Gilbert in the early 20th century.

  19. Spawning, fertilization, and larval development of Potamocorbula amurensis (Mollusca: Bivalvia) from San Francisco Bay, California

    In Potamocorbula amurensis time for development to the straight-hinge larval stage is 48 hr at 15??C. Potamocorbula amurensis settles at a shell length of approximately 135 ??m 17 to 19 days after fertilization. Our observations of timing of larval devdlopment in P. amurensis support the hypothesis of earlier workers that its route of initial introduction to San Francisco Bay was as veliger larvae transported in ballast water by trans-Pacific cargo ships. The length of the larval period of P. amurensis relative to water mass residence times in San Francisco Bay suggests that it is sufficient to allow substantial dispersal from North Bay to South Bay populations in concordance with previous observations that genetic differentiation among populations of P. amurensis in San Francisco Bay is low. Potamocorbula amurensis is markedly euryhaline at all stages of development. Spawning and fertilization can occur at salinities from 5 to 25 psu, and eggs and sperms can each tolerance at least a 10-psu step increase or decrease in salinity. Embryos that are 2 hr old can tolerate the same range of salinities from (10 to 30 psu), and by the time they are 24 hr old they can tolerate the same range of salinities (2 to 30 psu) that adult clams can. The ability of P. amurensis larvae to tolerate substantial step changes in salinity suggests a strong potential to survive incomplete oceanic exchanges of ballast water and subsequent discharge into receiving waters across a broad range of salinities.

  20. Magnetic SANS study of a sintered Nd–Fe–B magnet: Estimation of defect size

    International Nuclear Information System (INIS)

    The magnetic microstructure of an isotropic sintered Nd–Fe–B permanent magnet was studied at room temperature by means of unpolarized magnetic-field-dependent small-angle neutron scattering (SANS). Although the microstructure of the material consists of micron-sized Nd2Fe14B crystallites that are separated by a (low volume fraction) nanometer-sized Nd-rich phase, the SANS signal contains a significant contribution due to spin misalignment, which is evidenced by an enhanced scattering signal along the direction of the applied field. The origin of this spin misalignment is presumably related to the perturbing effect of the Nd-rich interphases. Analysis of the SANS data in terms of the autocorrelation function of the spin misalignment provides an almost field-independent length scale lC ? 40 nm, which, for soft magnetic materials, is usually taken as a measure for the size of inhomogeneously magnetized regions around lattice imperfections. Comparison of our results with a phenomenological expression for lC based on micromagnetic theory suggests that the large anisotropy field of the Nd2Fe14B phase (which is of the order of 8 T) reduces the size of gradients in the spin microstructure, so that, for hard magnetic materials, lC represents the (field-independent) size of the characteristic defect in the microstructure

  1. Tectonic inversion events in the western San Jorge Gulf Basin from seismic, borehole and field data

    The San Jorge Gulf Basin, located in Central Patagonia, has been interpreted as a Jurassic-Cretaceous rift basin that was later inverted mainly in its western sector. Consequently, the Bernardides System formed as a set of foreland contractional structures that constitute the core of the Patagonian broken foreland, exhuming continental deposits of the Cretaceous Chubut Group, 500 km away from the Pacific trench. In spite of the intense research done in the San Jorge Gulf Basin many aspects remain under discussion, particularly those regarding the age of uplift of the Bernárdides System. In order to unravel the tectonic evolution of the western San Jorge Gulf Basin (Río Mayo Sub-Basin), we analyzed subsurface information (2D and 3D seismic lines and oil wells) located in the western area of the basin and compared this with surface data of the southern Bernárdides System. Based on our interpretation, the western part of the basin could have been uplifted in a series of deformational events that began as early as late Early Cretaceous, related to the initial uplift of the Patagonian broken foreland, during the early stages of South Atlantic opening. Subsequent stages of tectonic reactivation identified in this system have selectively inverted previous extensional structures according to the variable direction of the greatest horizontal stress (?1) acting at each time.

    GEOPHYSICAL OBJECTIVES: The goals of work done this quarter were to (1) refine the maps of seismic-derived porosity for the upper Grayburg for reapplication to the production model, (2) determine rock fabric and porosity patterns for the lower Grayburg and the upper San Andres, (3) relate any seismic-derived porosity characteristics, particularly seismic waveform attributes, to the historical production of oil allocated to lower Grayburg and San Andres zones, and (4) to test other geologic attributes for possible inter-relationships. GEOLOGIC OBJECTIVES: Continue the integrated geological/geophysical effort to develop a usable seismic velocity/log porosity transform for each Grayburg producing interval. The lower Grayburg and San Andres core were revisited to glean lithology and porosity information for the seismic inversion model. Update recent production and injection for each well in the study area. Add new production and injection wells to spreadsheet. Continue evaluation of effectiveness of recent completions, plug backs and injector conversions by monitoring oil production and produced water composition. ENGINEERING OBJECTIVES: To build the most accurate reservoir picture by continued integration of all data types available and utilize that model to optimize oil production. Monitoring and testing of new and worked-over wells continues to test the early production models. Methods to improve water quality are being evaluated using normal field management procedures.

  3. Nondestructive testing of high-temperature alloys by small angle neutron scattering (SANS)

    International Nuclear Information System (INIS)

    The suitability of the Small Angle Neutron Scattering (SANS) technique for the measurement of microstructural parameters of high-temperature alloys has been studied. The aim was the non-destructive determination of the creep damage for the estimation of the residual lifetime of service loaded gas turbine blades. In the first step the quantitative correlation between the SANS Signal and the microstructure of the material has been investigated using two oxide dispersion strengthened (ODS) alloys of simple microstructure. The size distributions of the dispersoid in the as-received alloy and the thermally induced growth of the dispersoid have been measured. Good agreement with results of transmission electron microscopy examinations was found. Subsequently the relationship between the SNS signal and the strain of a typical, creep loaded, ?'-strengthened Ni-base superalloy has been investigated. In a series of creep specimens made from the cast superalloy IN100, systematically increasing amounts of creep strain have been produced. With these specimens two parameters can be derived from the SANS scattering curve, each pair of values having a clear relationship with the creep strain. A hypothesis is discussed concerning the related scattering mechanism. (orig.)

  8. Mercury in San Francisco Bay forage fish

    International Nuclear Information System (INIS)

    In the San Francisco Estuary, management actions including tidal marsh restoration could change fish mercury (Hg) concentrations. From 2005 to 2007, small forage fish were collected and analyzed to identify spatial and interannual variation in biotic methylmercury (MeHg) exposure. The average whole body total Hg concentration was 0.052 ?g g-1 (wet-weight) for 457 composite samples representing 13 fish species. MeHg constituted 94% of total Hg. At a given length, Hg concentrations were higher in nearshore mudflat and wetland species (Clevelandia ios, Menidia audens, and Ilypnus gilberti), compared to species that move offshore (e.g., Atherinops affinis and Lepidogobius lepidus). Gut content analysis indicated similar diets between Atherinops affinis and Menidia audens, when sampled at the same locations. Hg concentrations were higher in sites closest to the Guadalupe River, which drains a watershed impacted by historic Hg mining. Results demonstrate that despite differences among years and fish species, nearshore forage fish exhibit consistent Hg spatial gradients. - Total mercury in estuarine forage fish varies with species, habitat, and proximity to a historic mercury mine.

  9. Teaching Geology at San Quentin State Prison

    The students enrolled in our Geology 215 class are about as on-traditional as it gets. They range in age from about 20 - 50 years old, they are all male, all from under-represented ethnic groups, and they are all serving time in one of the country's most notorious prisons. We teach in a degree-granting community college program inside California's San Quentin State Prison. The program is run entirely by volunteers, and students who participate in educational programs like ours are about 5 times less likely to return to prison than the general inmate population in California. The prison population of California is ethnically diverse, though minorities are present in higher proportion than in the general population. Last semester, our geology class happened to be composed entirely of minorities even though the college program serves the full spectrum of the prison population. While some trends in geoscience education encourage the use of technology in the classroom, security restrictions prevent us from using even some of the simplest visual aids. Faced with these challenges, we have developed an inquiry-based syllabus for an introductory Geology class at the community college level. We find that kinaesthetic learning activities such as urban geologic mapping and acting out plate tectonic motions from ridge to trench (complete with magnetic pole polarity shifts) are not only possible in restricted learning environments, but they promote student learning in unexpected ways.

  10. SYNROC densification: SEM correlation to SANS

    International Nuclear Information System (INIS)

    SYNROC is among the first crystalline waste forms introduced to radioactive waste management as alternative host to glass for disposal in underground repository. Variation of densification parameters obtained from scanning electron microscopy of microstructure and small-angle neutron scattering investigation has been correlated in the present paper. Three specimens of SYNROC were characterized. One was green pellet uniaxially compacted powder, two others were hot-isostatically compacted at 1000? 1000 bar and 1300? 1000 bar 2h dwell time respectively. The compactness was found to increase with sintering. The SEM image of microstructures showed the progress towards densification of the samples. The SANS profile suggested that pores in three widely separated length scales were present in the samples. The average radius of the size distributions at three length scales for the green pellet was 300 nm, 75 nm and 10 nm. These values for the first hot compacted sample, get modified to 126 nm, 73 nm and 20 nm, respectively. For the second hot compacted sample, the average radius of the pore size distributions become as 84 nm, 80 nm and 20 nm. It is evident that the larger diameter pores follow the trend of densification. The bigger pores from SEM imaged microstructures also follow the same trend of densification

  11. The radiological accident in San Salvador

    International Nuclear Information System (INIS)

    In February 1989 a radiological accident occurred in San Salvador at an industrial irradiation facility for sterilizing prepackaged medical products. A movable rack holding a 660 TBq (18 kCi) 60Co source jammed in the exposed position. The operator managed to bypass degraded safety systems and enter the irradiation chamber and, with two helpers, free the rack and lower it manually into the storage pool. The three workers were exposed to very high doses and developed acute radiation syndrome. Initial treatment locally and subsequent more sophisticated treatment in Mexico City was effective in countering the acute effects. However, the legs and feet of two men were so seriously injured that amputation was necessary. Moreover, despite the medical efforts, the most exposed worker died six months after the accident from radiation induced lung damage complicated by a lung injury sustained during treatment. As there are more than 160 industrial irradiation facilities throughout the world, some in countries with little or no infrastructure for radiological protection, an international review was undertaken to document the facts and define lessons for all with safety responsibilities at such facilities. The paper provides a brief summary of the findings of that review. (author). 1 ref., 3 figs

  12. Radiological survey of San Diego Bay

    International Nuclear Information System (INIS)

    A radiological survey of three sites in San Diego Bay provided the basis for the following conclusions: 1. Small quantities of Co-60 (0.02-0.05 pCi/g) are present in the bottom sediments in some areas of the harbor at the Submarine Base. Most, if not all, of the Co-60 contamination present probably originated prior to the earlier 1967 survey that reported Co-60 levels as much as 300 times larger than those observed in this study. The highest Co-60 concentration measured is now less than one percent of the normal background radioactivity in harbor sediment samples. 2. No tritium or gamma-ray emitters, other than trace amounts of those occurring naturally, were detected in surface water from the dock areas or in nearby drinking water supplies. 3. Only radionuclides of natural origin and trace amounts of Cs-137 from fallout of previous nuclear weapons tests were detected in samples of kelp, algae, and fish taken from the harbor at the Submarine Base. 4. Gamma-ray surveys of the harbors near the docking areas and along shorelines and beaches near the shipyards failed to detect any exposure rates above background. 3 refs., 4 figs., 3 tabs

    Gold mining is responsible for most Hg pollution in developing countries. The aims of this study were to assess the levels of total Hg (T-Hg) in human hair, fish, water, macrophyte, and sediment samples in the gold mining district of San Martin de Loba, Colombia, as well as to determine fish consumption-based risks for T-Hg ingestion. T-Hg levels were measured by electrothermal atomization and atomic absorption spectroscopy. The overall mean T-Hg level in hair for humans in the mining district of San Martin de Loba was 2.12 ?g/g, whereas for the reference site, Chimichagua, Cesar, it was 0.58 ?g/g. Mean T-Hg levels were not different when considered within localities belonging to the mining district but differed when the comparison included Chimichagua. T-Hg levels in examined locations were weakly but significantly associated with age and height, as well as with fish consumption, except in San Martin de Loba. High T-Hg concentrations in fish were detected in Pseudoplatystoma magdaleniatum, Caquetaia kraussii, Ageneiosus pardalis, Cyrtocharax magdalenae, and Triportheus magdalenae, whereas the lowest appeared in Prochilodus magdalenae and Hemiancistrus wilsoni. In terms of Hg exposure due to fish consumption, only these last two species offer some guarantee of low risk for Hg-related health problems. Water, floating macrophytes, and sediments from effluents near mining sites also had high Hg values. In mines of San Martin de Loba and Hatillo de Loba, for instance, the geoaccumulation index (I(geo)) for sediments reached values greater than 6, indicating extreme pollution. In short, these data support the presence of a high Hg-polluted environment in this mining district, with direct risk for deleterious effects on the health of the mining communities. PMID:25354433

  15. Evolving Hazard Monitoring and Communication at San Vicente Volcano, El Salvador

    El Salvador has 20 potentially active volcanoes, four of which have erupted in the last 100 years. Since San Vicente Volcano has had no historic eruptions, monitoring is not a high priority; especially given the current eruptive crisis at San Miguel Volcano. Though probability of eruptive hazards remains low at San Vicente, it is arguably one of the most hazardous volcanoes in the country due to rainfall-induced landslides and debris-flow risk. At least 250 deaths occurred in November 2009 from landslides and debris flows triggered by Hurricane Ida. This disaster caused the Universidad de El Salvador - Facultad Multidisciplinaria Paracentral (UES-FMP, San Vicente, El Salvador) to partner with governmental and nongovernmental organizations (including the U.S. Peace Corps, U.S. Fulbright Program, Korean International Cooperation Agency, Protección Civil and the Centro de Protección para Desastres (CEPRODE)) to focus its faculty and student research toward hazard monitoring and risk studies. Newly established monitoring efforts include: measurement of surface cracks and localized rainfall by Protección Civil and local residents using crude extensometers and rain gauges; installation of six weather stations that operate within the most at-risk municipalities; seismic refraction surveys to better characterize stratigraphy and seasonal water table changes; and most recently, a USAID/NSF-funded initiative partnered with the UES-FMP to monitor seasonal hydrologic conditions related to flooding and groundwater recharge. The information from these initiatives is now used to communicate current conditions and warnings through a network of two-way radios established by CEPRODE and Protección Civil. Representatives from the multi-institutional team also communicate the data to authorities who make better-informed decisions regarding warnings and evacuations, as well as determine suitable areas for population relocation in the event of a crisis. Data will eventually be used to model and forecast potential hazard events.

    Full Text Available A major and trace element based characterization of the metasedimentary protoliths of three metamorphic units of Sierra de San Luis (Pringles Metamorphic Complex, San Luis Formation and Conlara Metamorphic Complex is presented. Geochemistry indicates a dominance of shales in the protoliths of San Luis Formation, whereas greywackes and shales made up the Conlara Metamorphic complex and mainly greywackes, the Pringles Metamorphic Complex. Both major element data and trace element ratios (i.e. Th/Sc, Th/U, indicate a source with an average upper crustal composition for the protoliths of the Pringles Metamorphic Complex, the San Luis Formation and the shales of the Conlara Metamorphic complex. A component with less evolved signature may be inferred for the metagreywackes of the Conlara metamorphic Complex. Mixed sourced detritus are indicated for the three units with clastic material resulting mainly from both andesitic and acidic/recycled detritus. The overall data consistently suggest a continental island arc and/or active margin setting as the more probable geodynamic scenario for the deposition of the sedimentary precursors of the studied units. In this context, a back-arc setting can account for the mixed nature of the inferred source areas with uplifted old basement and arc-related detritus as the end members of the mixtures. The inferred back-arc basin would have evolved through the Cambrian receiving the sediments derived from the Pampean Orogen to the east combined with probably some old crust exposures and to the west the source might have been controlled by the active continental margin.

    The linear motor is one of the most important developments in electrical drive technology. However, it only, began to be adopted on a large scale at the beginning of the 1990's and will not be considered a mature technology until well into the next millennium. Actuators based on linear motor technology have a number of technical advantages including high speed, high positional accuracy and fine resolution. They also require fewer component parts. Some precautions are necessary when using linear motors. Care must be taken to avoid overheating and excessive vibration, and the magnetic components must be protected.

    An assessment of the indoor air quality (IAQ) of the San Francisco Federal Building (SFFB) was conducted on May 12 and 14, 2009 at the request of the General Services Administration (GSA). The purpose of the assessment was for a general screening of IAQ parameters typically indicative of well functioning building systems. One naturally ventilated space and one mechanically ventilated space were studied. In both zones, the levels of indoor air contaminants, including CO2, CO, particulate matter, volatile organic compounds, and aldehydes, were low, relative to reference exposure levels and air quality standards for comparable office buildings. We found slightly elevated levels of volatile organic compounds (VOCs) including two compounds often found in"green" cleaning products. In addition, we found two industrial solvents at levels higher than typically seen in office buildings, but the levels were not sufficient to be of a health concern. The ventilation rates in the two study spaces were high by any standard. Ventilation rates in the building should be further investigated and adjusted to be in line with the building design. Based on our measurements, we conclude that the IAQ is satisfactory in the zone we tested, but IAQ may need to be re-checked after the ventilation rates have been lowered.

  20. Emissions of organic carbon and methane from petroleum and dairy operations in California's San Joaquin Valley

    Petroleum and dairy operations are prominent sources of gas-phase organic compounds in California's San Joaquin Valley. It is essential to understand the emissions and air quality impacts of these relatively understudied sources, especially for oil/gas operations in light of increasing US production. Ground site measurements in Bakersfield and regional aircraft measurements of reactive gas-phase organic compounds and methane were part of the CalNex (California Research at the Nexus of Air Quality and Climate Change) project to determine the sources contributing to regional gas-phase organic carbon emissions. Using a combination of near-source and downwind data, we assess the composition and magnitude of emissions, and provide average source profiles. To examine the spatial distribution of emissions in the San Joaquin Valley, we developed a statistical modeling method using ground-based data and the FLEXPART-WRF transport and meteorological model. We present evidence for large sources of paraffinic hydrocarbons from petroleum operations and oxygenated compounds from dairy (and other cattle) operations. In addition to the small straight-chain alkanes typically associated with petroleum operations, we observed a wide range of branched and cyclic alkanes, most of which have limited previous in situ measurements or characterization in petroleum operation emissions. Observed dairy emissions were dominated by ethanol, methanol, acetic acid, and methane. Dairy operations were responsible for the vast majority of methane emissions in the San Joaquin Valley; observations of methane were well correlated with non-vehicular ethanol, and multiple assessments of the spatial distribution of emissions in the San Joaquin Valley highlight the dominance of dairy operations for methane emissions. The petroleum operations source profile was developed using the composition of non-methane hydrocarbons in unrefined natural gas associated with crude oil. The observed source profile is consistent with fugitive emissions of condensate during storage or processing of associated gas following extraction and methane separation. Aircraft observations of concentration hotspots near oil wells and dairies are consistent with the statistical source footprint determined via our FLEXPART-WRF-based modeling method and ground-based data. We quantitatively compared our observations at Bakersfield to the California Air Resources Board emission inventory and find consistency for relative emission rates of reactive organic gases between the aforementioned sources and motor vehicles in the region. We estimate that petroleum and dairy operations each comprised 22% of anthropogenic non-methane organic carbon at Bakersfield and were each responsible for 8-13% of potential precursors to ozone. Yet, their direct impacts as potential secondary organic aerosol (SOA) precursors were estimated to be minor for the source profiles observed in the San Joaquin Valley.

    Full Text Available Se registran concentraciones de hierro disuelto (Fe d) en la zona del mínimo de oxígeno (ZMO) del golfo de California, que se ubicó frente al relieve del umbral de San Esteban y entre el Agua Subsuperficial Subtropical (ASS) y el Agua Intermedia del Pacífico. La concentración promedio de Fe d en la [...] ZMO fue de 3.84 ± 2.48 nM, con un valor mínimo de 1.48 nM y un máximo de 10.02 nM. Estas concentraciones son mayores y están enriquecidas (8:1) en relación con las de la ZMO del océano Pacífico Nororiental Tropical (0.25-1.2 nM), cuyas aguas ingresan al golfo de California mediante el ASS. La resuspensión de sedimentos y aguas ricas en Fe d provocan el incremento de este metal en las estaciones aledañas al umbral de San Esteban. Por otro lado, los valores relativamente menores son producto de la desnitrificación en la zona subóxica en las estaciones más alejadas del umbral de San Esteban. Abstract in english Dissolved iron (Fe d) concentrations are reported for the Gulf of California oxygen minimum zone (OMZ), which was located in front of San Esteban sill, between Subtropical Subsurface Water (SSW) and Pacific Intermediate Water. Mean Fe d concentration in the OMZ was 3.84 ± 2.48 nM, with minimum and m [...] aximum values of 1.48 and 10.02 nM. These concentrations are higher and are enriched in relation to the Tropical Northeast Pacific Ocean OMZ (0.25-1.2 nM), whose waters enter the gulf through SSW. Sediment resuspension and Fe d-enriched waters cause the observed Fe increase at the stations located near San Esteban sill. On the other hand, the relatively lower Fe d concentrations found at the stations farthest from the sill are the result of denitrification in the suboxic zone.

    A linear perturbation computation method for predicting the linear growth of three-dimensional hydrodynamic instabilities in unsteady compressible flows, with planar or spherical symmetries, is presented. Simple yet demanding configurations of spherically converging flows, taken from gas dynamics, illustrate the method capabilities at yielding predictive results. Examples of more complex flow configurations point out the interest of such an approach in the context of inertial confinement fusion applications. (authors)

    Full Text Available Se calcularon los componentes del balance hídrico en San Antonio Oeste (SAO, Argentina. SAO se localiza en el sector Nororiental de la Patagonia, en una zona semiárida de escasa productividad agropecuaria como consecuencia del elevado déficit anual y la insuficiencia del drenaje superficial. El objetivo principal de este trabajo es evaluar el déficit en SAO a partir de metodologías adaptadas a las condiciones de sitio. Para ello se realizaron balances hídricos climáticos normales y secuenciales de acuerdo con Thornthwaite y Matter (1955 en base a datos pertenecientes a la estación SAO del Servicio Meteorológico Nacional. Se seleccionó y calibró el método de estimación de la evapotranspiración potencial más adecuado, mediante una comparación entre cuatro métodos empíricos y FAO Penman-Monteith. Para la caracterización de las condiciones edáficas del terreno se realizó un análisis de textura del suelo y contenido de materia orgánica en tres sitios representativos próximos a la estación SAO. El método de evapotranspiración potencial de Christiansen presentó la mayor correlación (r2=0,994 cuyo error relativo medio es 1,1 y 24,2 % en verano e invierno, respectivamente. Las interrelaciones entre las variables precipitación y evapotranspiración potencial en los balances hídricos normales señalaron volúmenes anuales deficitarios en todos los períodos de análisis (1961-2000 del orden de los 1170 mm. Estos volúmenes ocurren principalmente durante los meses de septiembre a marzo, concentrando más del 80 % del total anual. El período que mostró mayor déficit es el 1971-1980 (1258 mm/año. En contraposición, en los decenios 1981-1990 y 1991-2000 los valores de déficit fueron moderadamente inferiores (approx. 12 % al citado período. Los aportes metodológicos y resultados obtenidos deben ser considerados en las políticas de planificación y manejo del riego, máxime en un contexto económico de creciente diversificación productiva.

  7. Performance improvement of multilayered neutron monochrometer for KUR-SANS

    International Nuclear Information System (INIS)

    Small angle neutron scattering (SANS) experiments have been used widely to investigate the structure of the size of 1-100 nm such as the living body molecules. The collimated beam with comparatively large cross section and wave length resolution of about 20% is necessary in high strength for the SANS in the nuclear reactor neutron source. The multilayered neutron monochromator is compact and with no performance deterioration due to the breakdown of mechanical movable part. Then, the multilayered neutron monochromator has been used in KUR-SANS. In the SANS experiment, necessary neutron wave length is different depending on the size of the sample. In this research, the wave length resolution of 20% was requested at the vicinity of the peak of the neutron spectrum in consideration of efficiently using neutron and increasing the variation of the neutron wave length in the SANS experiment. Multilayered neutron monochromator was developed using ion beam spattering method, and the performance was evaluated as the highest level in the world. Reflectivity of the first Bragg peak showed 0.81 with peak reflectivity 0.86 and reflectivity by the second Bragg conditions to obstruct making of the neutron monochrome was suppressed to 5.0 x 10-3 or less, and can be suppressed to 3.0 x 10-5 or less by uniting the reflection type monochromator twice. About 4.4 times strength were obtained with the monochromator. (T.Tanaka)

  8. Prediction of maximum earthquake intensities for the San Francisco Bay region

    Science.gov (United States)

    Borcherdt, Roger D.; Gibbs, James F.

    1975-01-01

    The intensity data for the California earthquake of April 18, 1906, are strongly dependent on distance from the zone of surface faulting and the geological character of the ground. Considering only those sites (approximately one square city block in size) for which there is good evidence for the degree of ascribed intensity, the empirical relation derived between 1906 intensities and distance perpendicular to the fault for 917 sites underlain by rocks of the Franciscan Formation is: Intensity = 2.69 - 1.90 log (Distance) (km). For sites on other geologic units intensity increments, derived with respect to this empirical relation, correlate strongly with the Average Horizontal Spectral Amplifications (AHSA) determined from 99 three-component recordings of ground motion generated by nuclear explosions in Nevada. The resulting empirical relation is: Intensity Increment = 0.27 +2.70 log (AHSA), and average intensity increments for the various geologic units are -0.29 for granite, 0.19 for Franciscan Formation, 0.64 for the Great Valley Sequence, 0.82 for Santa Clara Formation, 1.34 for alluvium, 2.43 for bay mud. The maximum intensity map predicted from these empirical relations delineates areas in the San Francisco Bay region of potentially high intensity from future earthquakes on either the San Andreas fault or the Hazard fault.

  13. Solar energy system performance evaluation-seasonal report for Elcam San Diego, San Diego, California

    Science.gov (United States)

    1980-01-01

    The solar energy system, Elcam San Diego, was designed to supply domestic hot water heating for a single family residence located in Encinitas, California. System description, performance assessment, operating energy, energy savings, maintenance, and conclusions are presented. The system is a 'Sunspot' two tank cascade type, where solar energy is supplied to either a 66 gallon preheat tank (solar storage) or a 40 gallon domestic hot water tank. Water is pumped directly from one of the two tanks, through the 65 square feet collector array and back into the same tank. Freeze protection is provided by automatically circulating hot water from the hot water tank through the collectors and exposed plumbing when freezing conditions exist. Auxiliary energy is supplied by natural gas. Analysis is based on instrumented system data monitored and collected for one full season of operation.

  14. Holocene Geologic Slip Rate for the Banning Strand of the Southern San Andreas Fault near San Gorgonio Pass, Southern California

    We present the first Holocene geologic slip rate for the Banning strand of the southern San Andreas Fault in southern California. The southern San Andreas Fault splays into the sub-parallel Banning and Mission Creek strands in the northwestern Coachella Valley, and although it has long been surmised that the Banning strand eventually accommodates the majority of displacement and transfers it into San Gorgonio Pass, until now it has been uncertain how slip is actually partitioned between these two fault strands. Our new slip rate measurement, critically located at the northwestern end of the Banning strand, overlaps within errors with the published rate for the southern San Andreas Fault measured at Biskra Palms Oasis. This indicates that the majority of southern San Andreas Fault displacement transfers from the southeastern Mission Creek strand northwest to the Banning strand and into San Gorgonio Pass. Our result corroborates the UCERF3 hazard model, and is consistent with most previous interpretations of how slip is partitioned between the Banning and Mission Creek fault strands. To measure this slip rate, we used B4 airborne LiDAR to identify the apex of an alluvial fan offset laterally 30 ± 5 m from its source. We calculated the depositional age of the fan using 10Be in-situ cosmogenic exposure dating of 5 cobbles and a depth profile. We calculated a most probable fan age of 4.0 +2.0/-1.6 ka (1?) by combining the inheritance-corrected cobble ages assuming Gaussian uncertainty. However, the probability density function yielded a multi-peaked distribution, which we attribute to variable 10Be inheritance in the cobbles, so we favor the depth profile age of 2.2-3.6 ka. Combined, these measurements yield a late Holocene slip rate for the Banning strand of the southern San Andreas Fault of 11.1 +3.1/-3.3 mm/yr. This slip rate does not preclude possibility that some slip transfers north along the Mission Creek strand and the Garnet Hill fault, but it does confirm that the Banning strand has been the most probable rupture path for earthquakes nucleated on the southern San Andreas Fault over the past few thousand years, and is likely to remain so in the near future. This clarification of slip partitioning within the northwest Coachella Valley is timely given that the southern San Andreas Fault is considered overdue for a large earthquake.

  19. Variability of fault slip behavior along the San Andreas Fault in the San Juan Bautista Region

    An improved understanding of the time history of fault slip at depth is an essential step toward understanding the underlying mechanics of the faulting process. Using a waveform cross-correlation approach, we document spatially and temporally varying fault slip along the northernmost creeping section of the San Andreas Fault near San Juan Bautista (SJB), California, by systematically examining spatiotemporal behaviors of characteristically repeating earthquakes (CREs). The spatial distribution of pre-1998 SJB earthquake (1984-1998) fault slip rate inferred from the CREs reveals a ~15 km long low creep or partially locked section located near the 1998 Mw 5.1 SJB earthquake rupture. A finite-fault slip inversion reveals that the rupture of the 1998 SJB earthquake is characterized by the failure of a compact ~4 km2 asperity with a maximum slip of about 90 cm and corresponding peak stress drop of up to 50 MPa, whereas the mean stress drop is about 15 MPa. Following the 1998 earthquake, the CRE activity was significantly increased in a 5-10 km deep zone extending 2-7 km northwest of the main shock, which indicates triggering of substantial aseismic slip. The postseismic slip inferred from the CRE activity primarily propagated to the northwest and released a maximum slip of 9 cm. In this 5-10 km depth range, the estimated postseismic moment release is 8.6 × 1016 N m, which is equivalent to Mw 5.22. The aseismic slip distribution following the 1998 earthquake is not consistent with coseismic stress-driven afterslip but represents a triggered, long-lasting slow earthquake.

  1. Uranium mineralization in the San Marcos Volcanic Centre, Chihuahua, Mexico

    International Nuclear Information System (INIS)

    The Eocene San Marcos silicic volcanic centre contains about 30 radiometric anomalies, the most important of which are the San Marcos and Victorino uranium prospects. The volcanic centre is located in the eastern foothills of the Sierra Madre Occidental, 30 km northwest of the Chihuahua City. Volcanic activity began with eruption of the rhyodacitic Victorino Ignimbrite leading to collapse of the 20-km diameter San Marcos Caldera. A second stage of plinian eruptions at 46 million years led to collapse of the 5x15 km Tinaja Graben within the larger San Marcos Caldera. More that 200 m of rhyolitic Quintas Ignimbrite accumulated within this graben. A still smaller nested graben developed inside the Tinaja Graben, in which volcaniclastic deposits and a small volume of ignimbrite accumulated. Later volcanism led to the accumulation of extensive air falls. Ryolite domes erupted in different portions of the San Marcos volcanic centre throughout its history. Finally, the eastern half of the centre was down-faulted by a north-south striking range-front fault and was covered by alluvium. The San Marcos prospect is hosted by the Quintas Ignimbrite, and is interpreted to be the upper level of a vein system comprising two alteration events. The Victorino prospect is a stockwork developed in locally pyritized Victorino Ignimbrite. Wall rocks are haematitically altered. Pitchblende, now partially rimmed by uranophane, was precipitated probably by reduction of the ore fluids during reaction with magnetite-bearing, densely welded portions of the ignimbrite and/or with the pyrite-bearing portions. At other prospects in the volcanic centre, disseminated uranophane occurs in fault breccias, along intrusive dome contacts, and as small mantos in air falls and ignimbrites

    San Vicente volcano, also known as Chichontepec, is one of many volcanoes along the volcanic arc in El Salvador. This composite volcano, located about 50 kilometers east of the capital city San Salvador, has a volume of about 130 cubic kilometers, rises to an altitude of about 2180 meters, and towers above major communities such as San Vicente, Tepetitan, Guadalupe, Zacatecoluca, and Tecoluca. In addition to the larger communities that surround the volcano, several smaller communities and coffee plantations are located on or around the flanks of the volcano, and major transportation routes are located near the lowermost southern and eastern flanks of the volcano. The population density and proximity around San Vicente volcano, as well as the proximity of major transportation routes, increase the risk that even small landslides or eruptions, likely to occur again, can have serious societal consequences. The eruptive history of San Vicente volcano is not well known, and there is no definitive record of historical eruptive activity. The last significant eruption occurred more than 1700 years ago, and perhaps long before permanent human habitation of the area. Nevertheless, this volcano has a very long history of repeated, and sometimes violent, eruptions, and at least once a large section of the volcano collapsed in a massive landslide. The oldest rocks associated with a volcanic center at San Vicente are more than 2 million years old. The volcano is composed of remnants of multiple eruptive centers that have migrated roughly eastward with time. Future eruptions of this volcano will pose substantial risk to surrounding communities.

  3. Villa San Michele at Capri – a House with a distinct home for "Genius Loci"

    DEFF Research Database (Denmark)

    Fisker, Anna Marie; Danielsen, Mads Harder

    2015-01-01

    To address the relationship between House & Home from a theoretical perspective we set out on an journey towards Southern Europe; seeking answers to how a fellow Scandinavian here constructed a house, that was built of "Roba di Tiberio" - columns, capitals, fragments of statues - that was dug up on the spot. When we approached Capri by crossing the Neapolitan bay the first thing our eyes saw was the chapel of San Michele resting high above the blue waters at the top of the steep cliffs - on the edge of the abyss. This place is also the location of the Egyptian Sphinx, half lion, half woman; in a transient moment of clarity we had seen her face in our dreams. Capri was the place where eccentrics and wealthy fantasists could exorcize their demons: Goethe, Rilke and Nietzsche loved Capri. The island described by the Scandinavian poet Hans Christian Andersen visiting the Blue Grotta, the personal swimming hole of the Roman emperor Tiberius, as a “Fairy World”, was also the stupendous home of Axel Munthe. At Villa San Michele, entering through the beautiful loggias and the long row of arcades to the chapel that Munthe also restored, our eyes first felt the enigma of the spirit of the place - we wanted to know what happened. When Tiberius lived in his home on the island, the sphinx was already 1000 years old. Now the fantasy creature is on the last outpost of Munthe’s Villa San Michele where it lays majestic, at home, as the guardian spirit of the place – genius loci. It is our thesis that the spirit of the place adjoins a metaphysical core of architecture; and as the very core of architecture could be connected to an absolute truth so it seems that genius loci is related to truth; even though it is a truth that is not directly visible. We ask in this paper if it is a truth that is perennially present? And furthermore with which eyes are we to see this truth? Nietzsche was concerned with truth and the eyes that recognize truth: “There are various eyes. Even the Sphinx has eyes: and as a result there are various truths, and as a result there is no truth.” Let us enhance with the gaze of the Sphinx. For Nietzsche, the Sphinx becomes not the symbol of truth but of “truth”. The will to truth tempts us to many a hazardous enterprise. It is, says Nietzsche, the Sphinx who asks us questionable questions. That day at Villa San Michele we felt the enigma of the spirit of the place, but if we are going to hear the Sphinx ask us questions, all these riddling puzzles, we first have to ask the Sphinx to know how to ask questions. That genius loci are present in architectural theory owes much to the Scandinavian theoretician and architect Christian Norberg-Schulz, who emphasized considerations to the specific characteristics and atmosphere of a place. Is the atmosphere of Villa San Michele thus the key word in the understanding of the physical and metaphysical levels and layers of architectural language in this home of archaeological origin? We focus in our paper with these theoretical views on Villa San Michele through an architectural lens and perspective within the frames of House&Home on the language of architecture, and ask; can we explain the language of genius loci in Villa San Michele? Can we hereby clearly see how Axel Munthe - who was not an architect – could build a house at the very core of architecture and create a home caught between reality and dream?

  4. Strike-slip fault propagation and linkage via work optimization with application to the San Jacinto fault, California

    Science.gov (United States)

    Over multiple earthquake cycles, strike-slip faults link to form through-going structures, as demonstrated by the continuous nature of the mature San Andreas fault system in California relative to the younger and more segmented San Jacinto fault system nearby. Despite its immaturity, the San Jacinto system accommodates between one third and one half of the slip along the boundary between the North American and Pacific plates. It therefore poses a significant seismic threat to southern California. Better understanding of how the San Jacinto system has evolved over geologic time and of current interactions between faults within the system is critical to assessing this seismic hazard accurately. Numerical models are well suited to simulating kilometer-scale processes, but models of fault system development are challenged by the multiple physical mechanisms involved. For example, laboratory experiments on brittle materials show that faults propagate and eventually join (hard-linkage) by both opening-mode and shear failure. In addition, faults interact prior to linkage through stress transfer (soft-linkage). The new algorithm GROW (GRowth by Optimization of Work) accounts for this complex array of behaviors by taking a global approach to fault propagation while adhering to the principals of linear elastic fracture mechanics. This makes GROW a powerful tool for studying fault interactions and fault system development over geologic time. In GROW, faults evolve to minimize the work (or energy) expended during deformation, thereby maximizing the mechanical efficiency of the entire system. Furthermore, the incorporation of both static and dynamic friction allows GROW models to capture fault slip and fault propagation in single earthquakes as well as over consecutive earthquake cycles. GROW models with idealized faults reveal that the initial fault spacing and the applied stress orientation control fault linkage propensity and linkage patterns. These models allow the gains in efficiency provided by both hard-linkage and soft-linkage to be quantified and compared. Specialized models of interactions over the past 1 Ma between the Clark and Coyote Creek faults within the San Jacinto system reveal increasing mechanical efficiency as these fault structures change over time. Alongside this increasing efficiency is an increasing likelihood for single, larger earthquakes that rupture multiple fault segments. These models reinforce the sensitivity of mechanical efficiency to both fault structure and the regional tectonic stress orientation controlled by plate motions and provide insight into how slip may have been partitioned between the San Andreas and San Jacinto systems over the past 1 Ma.

    The Tulum Valley aquifer vulnerability and its correlation with the behavior of hydro chemical parameters related to new urban neighborhoods and uncontrolled waste disposal are discussed. A high vulnerability to contamination by substances solved in the recharge water at the San Juan river shore is estimated. A fast transport rate due to the high permeability is foreseen, as well as the existence of contamination sources related to waste disposals and populations without a sewer system. The results show that the mentioned populations and waste disposal sites are located at vulnerable zones of the area. A higher concentration of nitrates and nitrites is observed at the Southeast, due to the short permanency period of the water in the system, and to the reconcentration in zones with less permeable levels.

  6. Simulation of virtual SANS spectrometers at IBR-2 reactor

    International Nuclear Information System (INIS)

    The experience gained in the last 15 years of experimental studies of large-scale structures with the SANS instrument at the IBR-2 pulsed reactor in Dubna shows that some parameters of the spectrometer can be improved. In particular, it concerns reduction of the fast neutron and gamma backgrounds that limit the possibilities of studying weakly scattering objects. Another direction of improvement is to reduce a minimum momentum transfer value Qmin to study objects with larger characteristic dimensions. The paper investigates several configurations of the SANS machine at IBR-2. The Monte Carlo codes are used to calculate the parameters of such virtual instruments. An optimal instrument structure is proposed

    A way to generate a microporous carbon structure is to carbonize and optionally activate a high carbon yield polymeric precursor such as a phenol-formaldehyde resole. Carbonized samples are studied by SANS and nitrogen adsorption at 77 K. Porod plots and modified Guinier analysis of various geometries are presented. On the basis of the results obtained from SANS and nitrogen adsorption a carbonized resole model based on 4.0 nm solid structural units and a network of nearly isotropic pores is proposed.

  9. A SANS study of capillary condensation in porous media

    International Nuclear Information System (INIS)

    The authors use small angle neutron scattering (SANS) to study the microstructure of porous Vycor glass and the capillary condensation of fluids in the medium. Using a chord distribution model, they can predict the structure factor measured by SANS. Excellent agreement with the data is obtained. The fitted parameters characterize quantitatively the porous structure before and during the process of condensation, and are in good agreement with isotherm measurements. However, at the latest stages of the process, when all the pores are nearly filled, the model can no longer describe the system

    Meteorological factors influence dengue virus ecology by modulating vector mosquito population dynamics, viral replication, and transmission. Dynamic modeling techniques can be used to examine how interactions among meteorological variables, vectors and the dengue virus influence transmission. We developed a dengue fever simulation model by coupling a dynamic simulation model for Aedes aegypti, the primary mosquito vector for dengue, with a basic epidemiological Susceptible-Exposed-Infectious-Recovered (SEIR) model. Employing a Monte Carlo approach, we simulated dengue transmission during the period of 2010-2013 in San Juan, PR, where dengue fever is endemic. The results of 9600 simulations using varied model parameters were evaluated by statistical comparison (r2) with surveillance data of dengue cases reported to the Centers for Disease Control and Prevention. To identify the most influential parameters associated with dengue virus transmission for each period the top 1% of best-fit model simulations were retained and compared. Using the top simulations, dengue cases were simulated well for 2010 (r2 = 0.90, p = 0.03), 2011 (r2 = 0.83, p = 0.05), and 2012 (r2 = 0.94, p = 0.01); however, simulations were weaker for 2013 (r2 = 0.25, p = 0.25) and the entire four-year period (r2 = 0.44, p = 0.002). Analysis of parameter values from retained simulations revealed that rain dependent container habitats were more prevalent in best-fitting simulations during the wetter 2010 and 2011 years, while human managed (i.e. manually filled) container habitats were more prevalent in best-fitting simulations during the drier 2012 and 2013 years. The simulations further indicate that rainfall strongly modulates the timing of dengue (e.g., epidemics occurred earlier during rainy years) while temperature modulates the annual number of dengue fever cases. Our results suggest that meteorological factors have a time-variable influence on dengue transmission relative to other important environmental and human factors. PMID:26275146

  12. A summary of the San Francisco tidal wetlands restoration series

    Directory of Open Access Journals (Sweden)

    Larry R. Brown

    2003-10-01

    Full Text Available The four topical articles of the Tidal Wetlands Restoration Series summarized and synthesized much of what is known about tidal wetlands and tidal wetland restoration in the San Francisco Estuary (hereafter ?Estuary?. Despite a substantial amount of available information, major uncertainties remain. A major uncertainty with regard to fishes is the net benefit of restored tidal wetlands relative to other habitats for native fishes in different regions of the Estuary given the presence of numerous invasive alien species. With regard to organic carbon, a major uncertainty is the net benefit of land use change given uncertainty about the quantity and quality of different forms of organic carbon resulting from different land uses. A major challenge is determining the flux of organic carbon from open systems like tidal wetlands. Converting present land uses to tidal wetlands will almost certainly result in increased methylation of mercury at the local scale with associated accumulation of mercury within local food webs. However, it is unclear if such local accumulation is of concern for fish, wildlife or humans at the local scale or if cumulative effects at the regional scale will emerge. Based on available information it is expected that restored tidal wetlands will remain stable once constructed; however, there is uncertainty associated with the available data regarding the balance of sediment accretion, sea-level rise, and sediment erosion. There is also uncertainty regarding the cumulative effect of many tidal restoration projects on sediment supply. The conclusions of the articles highlight the need to adopt a regional and multidisciplinary approach to tidal wetland restoration in the Estuary. The Science Program of the CALFED effort provides an appropriate venue for addressing these issues.

    Full Text Available OBJETIVOS: Evaluar la carga de malaria en San Esteban, departamento de Olancho, Honduras, y ofrecer recomendaciones para su control. MÉTODOS: La malaria es causa de una considerable morbilidad en San Esteban. En 2006, los trabajadores sanitarios informaron un aumento de casos de malaria y solicitaro [...] n recomendaciones para su control. En 2005, en el laboratorio de San Esteban se detectaron 385 casos (316 por Plasmodium vivax y 69 por P. falciparum) en 4 007 frotis sanguíneos (tasa de positividad: 9,6%). Entre mayo y julio de 2006 se evaluó la carga de malaria y se hicieron las recomendaciones. Se revisaron los datos epidemiológicos de los casos confirmados de 2005 y 2006 y se aplicó una encuesta sobre conocimientos, actitudes y hábitos en los hogares para evaluar las prácticas relacionadas con el diagnóstico, el tratamiento y la prevención de la malaria. RESULTADOS: Entre mayo y julio de 2006 en San Esteban se detectaron 143 casos de malaria confirmados por el laboratorio (134 por P. vivax y 9 por P. falciparum), en comparación con 104 (79 por P. vivax y 25 por P. falciparum) entre mayo y julio de 2005. Entre enero de 2005 y julio de 2006 se detectaron 538 casos en San Esteban, con un aumento en la frecuencia entre mayo y octubre y la mayor incidencia en niños de 0 a 14 años. Se aplicaron 112 encuestas en 19 comunidades. De los que respondieron, 70% había tenido algún miembro del hogar con malaria, con una mayor frecuencia en las madres (45%) y los menores de 14 años (37%). La mayoría de los hogares carecían de protección contra los mosquitos, como mosquiteros para las camas y ventanas o fumigación de interiores. CONCLUSIONES: La malaria se mantiene en aumento en San Esteban, con una mayor incidencia en los niños. Se recomienda incrementar la disponibilidad y la promoción de mosquiteros tratados con insecticidas, mejorar la periodicidad y la cobertura de la fumigación de interiores y mejorar los hábitos de la comunidad mediante sesiones educativas. Abstract in english OBJECTIVES: To assess the burden of malaria in San Esteban, Department of Olancho, Honduras, and provide recommendations for control. METHODS: Malaria causes appreciable morbidity in San Esteban. In 2006, health workers reported an increase in malaria cases and requested recommendations for control. [...] In 2005, 385 cases (Plasmodium vivax, 316; P. falciparum, 69) were detected from 4 007 blood smears in the San Esteban laboratory (slide positivity rate = 9.6%). During May-July 2006, we assessed the burden of malaria and made recommendations. We reviewed epidemiologic data from slide-confirmed malaria cases in 2005 and 2006 and conducted a knowledge, attitudes, and practices survey in households to assess malaria diagnostic, treatment, and prevention practices. RESULTS: During May-July 2006, 143 laboratory-confirmed malaria cases were detected (P. vivax, 134; P. falciparum, 9) in San Esteban, compared with 104 (P. vivax, 79; P. falciparum, 25) in May-July 2005. From January 2005 to July 2006, 538 cases were detected in San Esteban, with increased frequency in May-October and the highest incidence in children 0-14 years old. We administered 112 surveys in 19 communities. Seventy percent of respondents reported a history of malaria in a household member, with the highest frequency reported in mothers (45%) and children under 14 years old (37%). Most households did not have mosquito protection such as bed nets, screens, or indoor residual insecticide. CONCLUSIONS: Malaria is ongoing in San Esteban, with increased incidence in children. We recommend increased availability and promotion of insecticide-treated bed nets, improved timing and coverage of indoor residual spraying, and improved community malaria practices through education sessions.

    2006-01-01

    Heat flow measurements along much of the San Andreas fault (SAF) constrain the apparent coefficient of friction (??app) of the fault to 0.2 should be detectable even with the sparse existing observations, implying that ??app for the creeping section is as low as the surrounding SAF. Because the creeping section does not slip in large earthquakes, the mechanism controlling its weakness is not related to dynamic processes resulting from high slip rate earthquake ruptures.

    Full Text Available Agricultural societies in the state of Mexico involved a form of legal resistance used by indigenous communities in the face of liberal individualization policies of communal property, particularly the federal seizure law of June 25, 1956. In this context, some residents of the towns of Santa Cruz and San Miguel created an agricultural association, as did residents from the town of San Pedro, to retain the collective use of their communal goods and acquire some legal capacity. This condition thus allowed indigenous peoples to present writs of amparo to defend "private" rights.

  9. Fossil content and structural relationships of the San Luis zone and the Caborca zone of NW Sonora, Mexico, suppression of the precambrian Z of Caborca

    International Nuclear Information System (INIS)

    In the Caborca region of western Sonora a Precambrian Z does not cover a unique Precambrian socle as previously believed. Two tectonic zones occur there instead: the San Luis Zone and the Caborca Zone. The first is comprised of the Precambrian San Luis socle of gneiss and granite, crossed by 1.1 Ga old anorthosites, the San Luis sedimentary cover, and, above it, a Lower Jurassic volcano-sedimentary sequence. The Caborca Zone consists of the Precambrian Bamori socle of parametamorphic rocks crossed by 1.1 Ga old Aibo granite, and of the Gamuza sedimentary cover. 1.1 Ga ago the two zones were far away from each other. They have been brought together by the Nevadian orogeny. Both zones are allochthonous, and the Caborca Zone is a nappe upon the San Luis Zone. The lowermost units of the Gamuza cover furnished psammocorals and a possible Pterophyllum jageri (?). Accordingly, its geological age is either Palaeozoic or Triassic.The San Luis cover furnished Nematophites [Prototaxites (?) and Nematothallus] from its lower part; Calcispongiae, Cardaicarpus' seeds, and Artisia from its upper part Thus, it is a Devono-Carboniferous unit. The study area belongs in the Baja-Borderland block, which underwent, an Eocene northwards drifting of about 900 - 1000 km, and a 30 celsius degrade to 40 celsius degrade clockwise rotation relative to the main part of Sonora.

  10. Population density, biomass, and age-class structure of the invasive clam Corbicula fluminea in rivers of the lower San Joaquin River watershed, California

    Corbicula fluminea is well known as an invasive filter-feeding freshwater bivalve with a variety of effects on ecosystem processes. However. C. fluminea has been relatively unstudied in the rivers of the western United States. In June 2003, we sampled C. fluminea at 16 sites in the San Joaquin River watershed of California, which was invaded by C. fluminea in the 1940s. Corbicula fluminea was common in 2 tributaries to the San Joaquin River, reaching densities of 200 clams??m-2, but was rare in the San Joaquin River. Biomass followed a similar pattern. Clams of the same age were shorter in the San Joaquin River than in the tributaries. Distribution of clams was different in the 2 tributaries, but the causes of the difference are unknown. The low density and biomass of clams in the San Joaquin River was likely due to stressful habitat or to water quality, because food was abundant. The success of C. fluminea invasions and subsequent effects on trophic processes likely depends on multiple factors. As C. fluminea continues to expand its range around the world, questions regarding invasion success and effects on ecosystems will become important in a wide array of environmental settings.

  11. Investigating Fault Slip and Rheology Along the San Andreas Fault in the San Juan Bautista Region

    An improved understanding of the connection between seismic behavior and fault-zone rheology at depth is an essential step toward understanding the underlying mechanics of the faulting process. We investigate the seismicity along the northernmost creeping section of the San Andreas fault near San Juan Bautista (SJB), California, by systematically examining spatiotemporal behaviors of the aftershock sequences following the 12 August 1998 Mw 5.1 SJB earthquake. This 1998 SJB earthquake was the largest historic earthquake in the SJB area and was associated with a large slow slip event. Using a waveform cross-correlation approach (Peng and Zhao, 2009, NatureGeo), we have detected previously uncataloged earthquakes (about 500 events), resolving details of the aftershock activity in a zone at a depth of 9 km about 7 km northwest of the 1998 SJB mainshock. This aftershock zone is marked by one of the highest changes in the seismicity rate, exhibiting a delayed peak (about 20 hours after the mainshock) in the rate of aftershocks preceded by a period of very low rate of aftershocks since the mainshock. Subsequently, the rate of aftershocks shows power-law decay with time for about 1 month, and then the aftershock activity approached the pre-earthquake background level. This temporal behavior of the aftershock activity is different from the predicted aftershock decay based on the model of Dieterich (1994, JGR). Instead, our observation is more consistent with the decay rate of aftershocks occurring in the transition zone between locked and stable slip, as simulated numerically by Kaneko and Lapusta (2008, JGR). Our waveform analysis also identifies over 20 repeating microearthquake sequences (or groups of earthquakes with similar waveforms) associated with the 1998 SJB mainshock. The majority of the sequences have events occurring in the first month of the postseismic period. In other words, they reflect short-lived, accelerated repeater recurrences activated by the 1998 SJB mainshock (Templeton et al., 2008, BSSA). This temporal pattern could indicate that these sequences are located at rheological boundaries between stable and unstable sliding in which the coseismic stresses were accumulated, rather than they represent small asperities surrounded by creeping areas. The sequences are localized in the northwest of the 1998 SJB hypocenter. We investigate the source process of the 1998 SJB mainshock using an empirical Green's function (eGf) approach (Dreger, 1994, GRL), finding the northwest directivity of the rupture propagation. We expect larger stress concentrations by the mainshock in the northwest region from the hypocenter in which the number of repeating earthquakes identified were activated, compared with those in southeast region. We evaluate the slip distribution of the 1998 SJB mainshock, by making use of a M 3.1 foreshock as the eGF. Our preliminary result shows the mainshock has a concentrated slip patch with radius on the order of 300-500 m, with peak slip of about 30 cm. The resulting peak stress drop is about 20 MPa. Efforts are ongoing to evaluate a spatial variation in Coulomb stress change based on our fault slip model and to explore the variability of fault frictional property along the San Andreas fault in the SJB region, with the constraints from the spatiotemporal variations of aftershock and repeating earthquake activities.

A state of the art SANS instrument was selected as a top-priority instrument by an instrument selection committee, which consisted of domestic users and HANARO personnel. An instrument development team and an international and domestic instrument advisory team were formulated. The guide and the instrument simulation were performed using Vitess software and the optimum basic design was completed based on the simulation results and the international advisory team reviews. The optimum design of the guide for the 40M SANS instrument was completed and the optimum basic design of the 40M the SANS instrument was also completed based on the Vitess simulation results. The Q range of the instrument will cover from 0.0008 to 1.0 A-1 and the maximum flux at a sample position can reach about 5.5x10 7 n/cm2sec. The simulation results and the basic design product will be used for the detailed design and the construction of the SANS instrument. The simulation results could be applied to the development of the other instrument

    Full Text Available The heritage of San rock art in southern Africa is globally acknowledged, and was one of the primary reasons for the successful nomination of the uKhahlamba/ Drakensberg Park in South Africa as a World Heritage Site.¹ Deterioration of rock paintings in the reserve could adversely affect the internat [...] ional status of the region, particularly as little has been achieved with regard to preserving the art for future generations. A study is currently under way in the Injisuthi and Giant's Castle areas of the park, to investigate the deterioration of San art; this article serves to introduce the project and to highlight some initial findings. Previous research on the weathering of San paintings has focused largely on either monitoring rock shelters² or investigating rock surfaces that are adjacent to the paintings. None of the methods applied in earlier investigations has considered the interface between rock and pigments, mainly because of the potential damage that may result from the use of tactile monitoring equipment. Recent advances in weathering research, using improved techniques to measure conditions at the rock surface where the San art is painted,³ provide new insights into surficial processes and suggest new lines of investigation.
