Evidence of Niche Partitioning under Ontogenetic Influences among Three Morphologically Similar Siluriformes in Small Subtropical Streams  

PubMed Central

Ontogenetic influences in patterns of niche breadth and feeding overlap were investigated in three species of Siluriformes (Heptapterus sp., Rhamdia quelen and Trichomycterus poikilos) aiming at understanding the species coexistence. Samplings were conducted bimonthly by electrofishing technique from June/2012 to June/2013 in ten streams of the northwestern state of Rio Grande do Sul, Brazil. The stomach contents of 1,948 individuals were analyzed by volumetric method, with 59 food items identified. In general Heptapterus sp. consumed a high proportion of Aegla sp., terrestrial plant remains and Megaloptera; R. quelen consumed fish, and Oligochaeta, followed by Aegla sp.; while the diet of T. poikilos was based on Simuliidae, Ephemeroptera and Trichoptera. Specie segregation was observed in the NMDS. Through PERMANOVA analysis feeding differences among species, and between a combination of species plus size classes were observed. IndVal showed which items were indicators of these differences. Niche breadth values were high for all species. The niche breadth values were low only for the larger size of R. quelen and Heptapterus sp. while T. poikilos values were more similar. Overall the species were a low feeding overlap values. The higher frequency of high feeding overlap was observed for interaction between Heptapterus sp. and T. poikilos. The null model confirmed the niche partitioning between the species. The higher frequency of high and intermediate feeding overlap values were reported to smaller size classes. The null model showed resource sharing between the species/size class. Therefore, overall species showed a resource partitioning because of the use of occasional items. However, these species share resources mainly in the early ontogenetic stages until the emphasized change of morphological characteristics leading to trophic niche expansion and the apparent segregation observed.

Evaluation of the chromium contamination at Ribeirão dos Bagres, Franca (SP), Brazil, by the ²¹?Pb method.  

PubMed

This paper presents a chronological study focusing the use of ²¹?Pb in four sediment cores collected at Ribeirão dos Bagres in the region of Franca, São Paulo State, Brazil. When evaluating the sedimentation rate by using the ²¹?Pb method, it was possible to monitor historical changes occurring in the concentrations of chromium present in the sediments. In order to do so, several specific parameters were determined in sediments, as chromium concentration, major oxides, organic matter, grain size, and chemical and physical-chemical parameters of waters. The sediments possessed a Cr concentration range of 0.83-26.25mg/kg that is below the world's average of shales. The sedimentation rates obtained from the ²¹?Pb analysis were between 0.07 and 0.77 g cm?²year?¹, while the linear sedimentation rate was from 0.6 to 3.2 cm/year. The adoption of the CIC (Constant Initial Concentration) ²¹?Pb model allowed characterize older sediments, aged 177 years, and younger sediments, aged 4 years. The organic matter in the sediments was more abundant in the first few centimeters of practically all profiles, and the analysis of oxides showed that silica is the major constituent of the sediments, in which there is predominance of sand and silt. In addition, the analysis of the physical and chemical parameters of waters indicated that they are suitable for navigation and natural harmony landscape. PMID:24184739

Trophic ecomorphology of Siluriformes (Pisces, Osteichthyes) from a tropical stream.  

PubMed

The present study analysed the relationship between morphology and trophic structure of Siluriformes (Pisces, Osteichthyes) from the Caracu Stream (22º 45' S and 53º 15' W), a tributary of the Paraná River (Brazil). Sampling was carried out at three sites using electrofishing, and two species of Loricariidae and four of Heptapteridae were obtained. A cluster analysis revealed the presence of three trophic guilds (detritivores, insectivores and omnivores). Principal components analysis demonstrated the segregation of two ecomorphotypes: at one extreme there were the detritivores (Loricariidae) with morphological structures that are fundamental in allowing them to fix themselves to substrates characterised by rushing torrents, thus permitting them to graze on the detritus and organic materials encrusted on the substrate; at the other extreme of the gradient there were the insectivores and omnivores (Heptapteridae), with morphological characteristics that promote superior performance in the exploitation of structurally complex habitats with low current velocity, colonised by insects and plants. Canonical discriminant analysis revealed an ecomorphological divergence between insectivores, which have morphological structures that permit them to capture prey in small spaces among rocks, and omnivores, which have a more compressed body and tend to explore food items deposited in marginal backwater zones. Mantel tests showed that trophic structure was significantly related to the body shape of a species, independently of the phylogenetic history, indicating that, in this case, there was an ecomorphotype for each trophic guild. Therefore, the present study demonstrated that the Siluriformes of the Caracu Stream were ecomorphologically structured and that morphology can be applied as an additional tool in predicting the trophic structure of this group.

Molecular phylogeny and biogeography of air sac catfishes of the Heteropneustes fossilis species complex (Siluriformes: Heteropneustidae).  

PubMed

The air sac catfish, Heteropneustes fossilis (Siluriformes: Heteropneustidae), is widely distributed in freshwaters of the Indian subcontinent and mainland southeast Asia. No comprehensive molecular studies that cover the broad distributional areas have been carried out to date. Here, we conducted molecular phylogenetic analyses using both mitochondrial and nuclear gene sequences to suggest that the Heteropneustes fossilis species complex consists of three clades that may potentially be separate species with distinct geographical distribution (southeast Asia, northeastern India, and southwestern India). The first and second clades are more closely related to each other than they are to the third clade. Within the first clade there is a basal divergence of a subclade consisting of individuals from the Upper Irrawaddy River basin of Myanmar, which share some morphological traits with members of the Indian clades. Our molecular and morphological data are congruent with hypotheses that the Early-Middle Miocene disconnection between the paleo-Tsangpo River and the Irrawaddy River caused the vicariant divergence between southeast Asian and northeastern Indian clades, and that the southeast Asian Heteropneustes originated from the Upper Irrawaddy.

Metazoan parasites of Mandi-amarelo Pimelodus maculatus and of Jundiá Rhamdia quelen (Osteichthyes: Siluriformes) of Paraíba do Sul River, Volta Redonda, Rio de Janeiro.  

PubMed

Forty-one specimens of mandi-amarelo Pimelodus maculatus Lacépède, 1803 (Siluriformes: Pimelodidae) and 54 specimens of jundiá Rhamdia quelen (Quoy & Gaimard, 1824) (Siluriformes: Heptapteridae) were collected from the Paraíba do Sul River, Volta Redonda, State of Rio de Janeiro, Brazil between November 2007 and October 2008. These fish underwent necropsy so their infracommunities of metazoan parasites could be studied. The same three species of parasites were collected in the two fish species studied. These were one monogenean, one nematode, and one hirudinean. Cucullanus pinnai (Travassos, Artiga, and Pereira, 1928) (Nematoda: Cucullanidae) and Aphanoblastella sp. (Monogenea: Dactylogyridae) were the dominant species with the highest prevalence in P. maculatus and R. quelen. The parasite species of P. maculatus and R. quelen showed an atypical over-dispersed pattern of distribution. No parasite species showed significant correlation between the body total length of the siluriform hosts and their prevalence and abundance. The parasite species richness showed a mean value of 0.87 ± 0.67 (0-2) and 0.57 ± 0.56 (0-2) in P. maculatus and R. quelen, respectively, and no correlation with the body total length. PMID:20943019

Neotropical Monogenoidea. 57. Revision and phylogenetic position of Scleroductus Jara & Cone, 1989 (Gyrodactylidae), with descriptions of new species from the Guatemalan chulin Rhamdia guatemalensis (Günther) (Siluriformes: Heptapteridae) in Mexico and the barred sorubim Pseudoplatystoma fasciatum (Linnaeus) (Siluriformes: Pimelodidae) in Brazil.  

PubMed

The diagnosis of Scleroductus Jara & Cone, 1989 (Gyrodactylidae) is amended to include viviparous species having a large spine associated with the ejaculatory duct within the male copulatory organ, two band-like projections originating from the posterior margin of the superficial bar and hooks evenly distributed along the haptoral margins. Two new species of Scleroductus are described from the external surfaces of siluriform fishes of Mexico and Brazil: Scleroductus lyrocleithrum n. sp. from the Guatemalan chulin Rhamdia guatemalensis (Günther) (Heptapteridae) in a cenote on the Yucatan Peninsula, Mexico; and Scleroductus angularis n. sp. from the barred sorubim Pseudoplatystoma fasciatum (Linnaeus) (Pimelodidae) in the Rio Tocantins, Tocantins, Brazil. Scleroductus sp. is recorded from the jundiá Rhamdia quelen (Quoy & Gaimard) (Heptapteridae) in the Iguaçu drainage of southern Brazil. Phylogenetic analyses of 18S rDNA suggest that Scleroductus (represented in the analyses by Scleroductus sp. from R. quelen), Ieredactylus Schelkle, Paladini, Shinn, King, Johnson, van Oosterhout, Mohammed & Cable, 2011 (represented by its type-species) and Gyrodactyloides Bychowsky, 1947 (represented by G. bychowskii Al'bova, 1948) comprise the sister taxon to the remaining viviparous gyrodactylids, with Scleroductus serving as the sister group to Ieredactylus + Gyrodactyloides. The clade containing the three taxa is supported by two putative synapomorphic features: two band-like projections (R1 sclerites) originating from the posterior margin of the superficial bar and a large spine associated with the ejaculatory duct within the male copulatory organ.

Metazoan parasites of Conorhynchos conirostris (Valenciennes, 1840) an endemic siluriform fish of the São Francisco basin, Brazil.  

PubMed

Specimens of Conorhynchos conirostris (Valenciennes, 1840) (Osteichthyes: Siluriformes) were collected from the upper São Francisco River (18 degrees 12'32''S, 45 degrees 15'41''W) in the municipality of Três Marias, Minas Gerais, Brazil, to investigate their parasitofauna. Of the 24 pirá fish collected, 8 were male (33.3%) and 16 were female (66.7%). Of this total, 12 were parasitized (50%). Nine species of parasites were found: Helobdella sp., Creptotrema creptotrema Travassos, Artigas & Pereira, 1928; Palaeocryptogonimus claviformis Szidat, 1954; metacercariae of Clinostomum sp. and of Austrodiplostomum compactum (Lutz 1928); Procamallanus (Spirocamallanus) sp. (young specimen); larvae of Anisakidae and Rhabdochona sp.; and Neoechinorhynchus sp. (young specimen). Helobdella sp. had the highest prevalence, followed by C. creptotrema (most abundant) and P. claviformis. Creptotrema creptotrema was dominant species in the parasite community of C. conirostris. There was no influence of the host size and sex on the prevalence and abundance of parasites, with P. claviformis being found only in male hosts. With the exception of Procamallanus (Spirocamallanus) sp., this was the first record of these parasites in C. conirostris. PMID:16445873

B chromosomes are considered additional and non-essential; they likely originate from A chromosomes and follow a distinct evolution. In fish, approximately half of the Neotropical species with B chromosomes are Characiformes and 35% are Siluriformes. There has been no report of B chromosomes in Auchenipteridae until this moment. B chromosomes found in a population of Parauchenipterus galeatus from the São Francisco River basin in the state of Minas Gerais (Brazil) were small, metacentric, totally heterochromatic and exhibited intra-individual and inter-individual variation. The diploid number was 58 chromosomes (22 metacentric, 16 submetacentric, 12 subtelocentric and 8 acrocentric). The nucleolar organizing regions were simple and the heterochromatin intercalated in the ribosomal sites, characterized by CMA(3) and DAPI fluorochromes, was of a GC-rich constitution. The 5S rDNA genes were located in an intercalary position in only one chromosome pair. An hypothesis about the origin of the B chromosomes in P. galeatus and a review on B chromosomes in catfish are also presented in this study. PMID:19394233

Molecular differentiation of species of the genus Zungaro (Siluriformes, Pimelodidae) from the Amazon and Paraná-Paraguay River basins in Brazil.  

PubMed

Fish species of the Zungaro genus (Siluriformes, Pimelodidae) are amongst the largest migratory fish in Latin America and have considerable economic importance for commercial fishing in Brazil. However, natural populations of this large catfish are experiencing a severe decline. There are significant taxonomical inconsistencies for this fish. Two geographically separated species of the fish were initially described, one endemic in the Amazon and another in the Paraná-Paraguay River basins. A taxonomic review had recently proposed that there is only one Zungaro species in Brazil, based on morphological data. We made a molecular study of Zungaro populations in an attempt to solve taxonomical inconsistencies and to analyze genetic diversity in natural populations of this genus. We analyzed two regions of the mitochondrial DNA (the control region and the ATPase 6 gene region) of individuals sampled from the Paraná-Paraguay River and Amazon River basins. Analyses based on p-distances and maximum likelihood phylogenetic models showed a genetic difference between populations corresponding to different species. Genetic differentiation between Zungaro populations was at the same level as that observed between other Siluriformes species, using the same DNA sequences. We conclude that Zungaro species of the Paraná-Paraguay River basin do not belong to the same species found in the Amazon basin. This finding has a significant implication for conservation of this fish, given that populations are disappearing at a high rate in the Paraná-Paraguay River basin, mainly due to impoundments.

Grand Rip and Grand Bang/Crunch cosmological singularities  

E-print Network

The present accelerated expansion of the universe has enriched the list of possible scenarios for its fate, singular or not. In this paper a unifying framework for analyzing such behaviors is proposed, based on generalized power and asymptotic expansions of the barotropic index $w$, or equivalently of the deceleration parameter $q$, in terms of the time coordinate. Besides well known singular and non-singular future behaviors, other types of strong singularities appear around the phantom divide in flat models, with features similar to those of big rip or big bang/crunch, which we have dubbed grand rip and grand bang/crunch respectively, since energy density and pressure diverge faster than $t^{-2}$ in coordinate time. In addition to this, the scale factor does not admit convergent generalized power series around these singularities with a finite number of terms with negative powers.

Grand Challenges of Enterprise Integration  

SciTech Connect

Enterprise Integration connects and combines people, processes, systems, and technologies to ensure that the right people and the right processes have the right information and the right resources at the right time. A consensus roadmap for Technologies for Enterprise Integration was created as part of an industry/government/academia partnership in the Integrated Manufacturing Technology Initiative (IMTI). Two of the grand challenges identified by the roadmapping effort will be addressed here--Customer Responsive Enterprises and Totally Connected Enterprises. Each of these challenges is briefly discussed as to the current state of industry and the future vision as developed in the roadmap.

American Experience: Grand Coulee Dam  

NSDL National Science Digital Library

Among many great national achievements during the Great Depression, the Grand Coulee Dam remains one of the most impressive. This fine website from the American Experience program complements a documentary that was first aired on PBS in 2012. The construction of this dam would, in the worlds of President Franklin Roosevelt, be part of a "planned promised land" that would transform the lives of farm families. The site includes a great interactive timeline, a photo gallery, and a short preview of the entire film. Additionally, the site includes two nice bonus videos, including one that deals with the processes of closing the spillway. The blog on the site includes several interesting posts on the history of the dam. Also, visitors have the opportunity to share their own stories about their own favorite iconic structures in the United States.

A large-scale phylogeny of Synodontis (Mochokidae, Siluriformes) reveals the influence of geological events on continental diversity during the Cenozoic.  

PubMed

To explain the spatial variability of fish taxa at a large scale, two alternative proposals are usually evoked. In recent years, the debate has centred on the relative roles of present and historical processes in shaping biodiversity patterns. In Africa, attempts to understand the processes that determine the large scale distribution of fishes and exploration of historical contingencies have been under-investigated given that most of the phylogenetic studies focus on the history of the Great Lakes. Here, we explore phylogeographic events in the evolutionary history of Synodontis (Mohokidae, Siluriformes) over Africa during the Cenozoic focusing on the putative role of historical processes. We discuss how known geological events together with hydrographical changes contributed to shape Synodontis biogeographical history. Synodontis was chosen on the basis of its high diversity and distribution in Africa: it consists of approximately 120 species that are widely distributed in all hydrographic basins except the Maghreb and South Africa. We propose the most comprehensive phylogeny of this catfish genus. Our results provide support for the 'hydrogeological' hypothesis, which proposes that palaeohydrological changes linked with the geological context may have been the cause of diversification of freshwater fish deep in the Tertiary. More precisely, the two main geological structures that participated to shape the hydrographical network in Africa, namely the Central African Shear zone and the East African rift system, appear as strong drivers of Synodontis diversification and evolution.

Population Dynamics and Diet of the Madamango Sea Catfish Cathorops spixii (Agassiz, 1829) (Siluriformes: Ariidae) in a Tropical Bight in Southeastern Brazil  

PubMed Central

The madamango sea catfish, Cathorops spixii (Siluriformes: Ariidae), is often among the most abundant fishes on the South American Atlantic coast. In the present study, conducted in shallow, non-estuarine coastal areas of Caraguatatuba Bight in southeastern Brazil, collections of this species, the most abundant member of the ichthyofauna, included primarily medium-sized individuals, indicating that the area may play a specific role in their development. Although studies of the local ichthyofauna have been much neglected, the area is economically important and its ecological significance is undervalued. This study primarily treats habitat use by C. spixii, assessing certain population parameters and the dietary composition. Monthly samples were taken from August 2003 through October 2004, with three trawls in two areas, corresponding to depths of about 1 to 4 m. The catfish showed two main peaks of abundance in the area, in April/May and July 2004. A mode around 9 cm SL persisted through time, and the entrance of younger recruits peaked from January to April. The low estimate for body-growth parameters (K?=?0.16) corroborates some K-strategist characteristics of the species. The asymptotic length was 27.3 cm SL and total mortality (Z) was 1.01 yr?1. Cathorops spixii showed an omnivorous feeding habit, preying mainly upon polychaetes, copepods and bivalves, with considerable seasonality in its diet. PMID:24282575

Grand rounds: a paradox in medical education.  

PubMed Central

OBJECTIVES: To assess perceptions of the importance and educational purpose of hospital grand rounds among physicians with administrative responsibilities, and to examine organizational aspects of grand rounds as educational events. DESIGN: Descriptive survey by mailed nonanonymous questionnaire. SETTING: All hospitals of more than 100 beds in Calgary. PARTICIPANTS: A total of 150 residency program directors and directors of departments and divisions in hospitals with differing teaching functions. RESULTS: A total of 120 questionnaires (80%) were returned, and the responses of 107 physicians were analysed. Each year in Calgary formal grand rounds activities occupy auditoriums and seminar rooms for more than 2000 hours. Most respondents considered grand rounds to be the main hospital-based continuing medical education activity in their discipline. Aspects of grand rounds considered to be important were updates in research, diagnosis and management, and only one third of the respondents felt that actual patient problems should always be the focus of discussion. The organization and planning of grand rounds revealed a paradox: despite the perceived educational importance, only 13% of rounds were based on a curricular structure, and 16% were based on needs assessments. The grand rounds topic was most often the choice of the presenter. CONCLUSIONS: The quantity of time devoted to grand rounds suggests importance in the routine workings of hospital departments. Grand rounds are used as a showcase for excellence in medical care or recent medical advances. It is paradoxical, therefore, that little interest appears to be shown in educational structure such as curriculum or evaluation of learning. Professional interaction is an inherent objective of traditional grand rounds. Further evaluation of the purpose and educational efficacy of traditional grand rounds is suggested. PMID:7828100

Orthopedic grand rounds can change resident practice.  

PubMed

This study sought to determine whether a grand rounds presentation could change resident practice. A 6-month review of all hip fracture patients 65 years and older at a single academic medical center was performed. The rate of addressing advanced directives and code status as documented in the medical record was noted. A grand rounds presentation was then given to the orthopedic department, and the medical records of hip fracture patients for the 12 months following the grand rounds were reviewed. In the 6 months prior to the grand rounds, orthopedic residents did not document code status or advanced directives in any of their admission or consultation notes. Following the grand rounds, orthopedic residents addressed advanced directives, code status, and contact person in 76% of their admission notes. There was a marked difference in the rate of documentation among residents who attended the grand rounds (88%), compared with residents who did not attend grand rounds (20%). Based on the results of this study, specifically whether residents attended grand rounds, this form of teaching can lead to changes in resident behavior. PMID:23710477

Perturbative SO(10) grand unification  

SciTech Connect

We consider a phenomenologically viable SO(10) grand unification model of the unification scale M{sub G} around 10{sup 16} GeV which reproduces the minimal supersymmetric standard model at low energy and allows perturbative calculations up to the Planck scale M{sub P} or the string scale M{sub st}. Both requirements strongly restrict a choice of Higgs representations in a model. We propose a simple SO(10) model with a set of Higgs representations {l_brace}2x10+16+16+45{r_brace} and show its phenomenological viability. This model can indeed reproduce the low-energy experimental data relating the charged fermion masses and mixings. Neutrino oscillation data can be consistently incorporated in the model, leading to the right-handed neutrino mass scale M{sub R}{approx_equal}M{sub G}{sup 2}/M{sub P}. Furthermore, there exists a parameter region which results the proton lifetime consistent with the experimental results.

A new imminent grand minimum?  

NASA Astrophysics Data System (ADS)

The planetary hypothesis of solar cycle is an old idea by which the planetary gravity acting on the Sun might have a non-negligible effect on the solar magnetic cycle. The advance of this hypothesis is based on phenomenological correlations between dynamical parameters of the Sun's movement around the barycenter of the Solar System and sunspots time series. In addition, several authors have proposed, using different methodologies that the first Grand Minima (GM) event of the new millennium is coming or has already begun. We present new fully three dimensional N-body simulations of the solar inertial motion (SIM) around the barycentre of the solar system in order to perform a phenomenological comparison between relevant SIM dynamical parameters and the occurrences of the last GM events (i.e., Maunder and Dalton). Our fundamental result is that the Sun acceleration decomposed in a co-orbital reference system shows a very particular behaviour that is common to Maunder minimum, Dalton minimum and the maximum of cycle 22 (around 1990), before the present prolonged minimum. We discuss our results in terms of a dynamical characterization of GM with relation to Sun dynamics and possible implications for a new GM event.

Karyotype and cytogenetic mapping of 9 classes of repetitive DNAs in the genome of the naked catfish Mystus bocourti (Siluriformes, Bagridae)  

PubMed Central

Background In the present study, conventional and molecular cytogenetic studies were performed in the naked catfish Mystus bocourti (Siluriformes, Bagridae). Besides the conventional Giemsa staining, fluorescence in situ hybridization (FISH) using nine classes of repetitive DNAs namely 5S and 18S rDNAs, U2 snRNA, the microsatellites (CA)15 and (GA)15, telomeric repeats, and the retrotransposable elements Rex1, 3 and 6. was also performed. Results M. bocourti had 2n?=?56 chromosomes with a karyotype composed by 11 m?+?11 sm?+?6 st/a and a fundamental number (NF) equal to 100 in both sexes. Heteromorphic sex chromosome cannot be identified. The U2 snRNA, 5S and 18S rDNA were present in only one pair of chromosomes but none of them in a syntenic position. Microsatellites (CA)15 and (GA)15 showed hybridization signals at subtelomeric regions of all chromosomes with a stronger accumulation into one specific chromosomal pair. FISH with the telomeric probe revealed hybridization signals on each telomere of all chromosomes and interstitial telomeric sites (ITS) were not detected. The retrotransposable elements Rex1, 3 and 6 were generally spread throughout the genome. Conclusions In general, the repetitive sequences were not randomly distributed in the genome, suggesting a pattern of compartmentalization on the heterochromatic region of the chromosomes. Little is known about the structure and organization of bagrid genomes and the knowledge of the chromosomal distribution of repetitive DNA sequences in M. bocourti represents the first step for achieving an integrated view of their genomes.

2010 Panel on the Biomaterials Grand Challenges  

PubMed Central

In 2009, the National Academy for Engineering issued the Grand Challenges for Engineering in the 21st Century comprised of 14 technical challenges that must be addressed to build a healthy, profitable, sustainable, and secure global community (http://www.engineeringchallenges.org). Although crucial, none of the NEA Grand Challenges adequately addressed the challenges that face the biomaterials community. In response to the NAE Grand Challenges, Monty Reichert of Duke University organized a panel entitled Grand Challenges in Biomaterials at the at the 2010 Society for Biomaterials Annual Meeting in Seattle. Six members of the National Academies—Buddy Ratner, James Anderson, Allan Hoffman, Art Coury, Cato Laurencin, and David Tirrell—were asked to propose a grand challenge to the audience that, if met, would significantly impact the future of biomaterials and medical devices. Successfully meeting these challenges will speed the 60-plus year transition from commodity, off-the-shelf biomaterials to bioengineered chemistries, and biomaterial devices that will significantly advance our ability to address patient needs and also to create new market opportunities.

Creationism in the Grand Canyon, Texas Textbooks  

NASA Astrophysics Data System (ADS)

AGU President Bob Dickinson, together with presidents of six other scientific societies, have written to Joseph Alston, Superintendent of Grand Canyon National Park, pointing out that a creationist book, The Grand Canyon: A Different View, is being sold in bookstores within the borders of the park as a scientific explanation about Grand Canyon geologic history. President Dickinson's 16 December letter urges that Alston clearly separate The Grand Canyon: A Different View from books and materials that discuss the legitimate scientific understanding of the origin of the Grand Canyon. The letter warns the Park Service against giving the impression that it approves of the anti-science movement known as young-Earth creationism, or that it endorses the advancement of religious tenets disguised as science. The text of the letter is on AGU's Web site http://www.agu.org/sci_soc/policy/sci_pol.html. Also, this fall, AGU sent an alert to Texas members about efforts by intelligent design creationists aimed at weakening the teaching of biological evolution in textbooks used in Texas schools. The alert pointed scientists to a letter, drafted by AGU, together with the American Institute of Physics, the American Physical Society, the Optical Society of America, and the American Astronomical Society, that urged the Texas State Board of Education to adopt textbooks that presented only accepted, peer-reviewed science and pedagogical expertise. Over 550 scientists in Texas added their names to the letter (http://www.agu.org/sci_soc/policy/texas_textbooks.pdf ), sent to the Board of Education on 1 November prior to their vote to adopt a slate of new science textbooks. The Board voted 11-5 in favor of keeping the textbooks free of changes advocated by groups supporting intelligent design creationism.

The Grand Tack model: a critical review  

E-print Network

The `Grand Tack' model proposes that the inner Solar System was sculpted by the giant planets' orbital migration in the gaseous protoplanetary disk. Jupiter first migrated inward then Jupiter and Saturn migrated back outward together. If Jupiter's turnaround or "tack" point was at ~1.5 AU the inner disk of terrestrial building blocks would have been truncated at ~1 AU, naturally producing the terrestrial planets' masses and spacing. During the gas giants' migration the asteroid belt is severely depleted but repopulated by distinct planetesimal reservoirs that can be associated with the present-day S and C types. The giant planets' orbits are consistent with the later evolution of the outer Solar System. Here we confront common criticisms of the Grand Tack model. We show that some uncertainties remain regarding the Tack mechanism itself; the most critical unknown is the timing and rate of gas accretion onto Saturn and Jupiter.

Hospital grand rounds in family medicine. Content and educational structure.  

PubMed Central

OBJECTIVE: To investigate hospital grand rounds in family medicine, to examine their content and organization, and to recommend improved educational structures for these ubiquitous continuing medical education events. DATA SELECTION: Retrospective analysis of titles and content of 358 family medicine grand rounds offered in the department of family medicine of a large urban hospital from mid-1983 to the end of 1994. FINDINGS: Only 10% of family medicine grand rounds were presented by family physicians. Most grand rounds were in the form of specialists exhibiting their own interests in a lecture format. Analysis of grand rounds titles showed no consistent pattern of topics but an emphasis on practical aspects of medical care. Patient-based presentations were uncommon, as were grand rounds with more than one speaker. CONCLUSIONS: The content and mix of topics appeared appropriate, but in the absence of a curricular structure, or evaluation of learning gain, it is difficult to assess the value of grand rounds.

Needs assessment for the Greenway Grand Forks-East Grand Forks development and public education  

NASA Astrophysics Data System (ADS)

Following the flood of 1997, the U.S. Army Corps of Engineers included the Greenway Grand Forks---East Grand Forks (the Greenway) as a flood control measure for Grand Forks, North Dakota and East Grand Forks, Minnesota. It extends along both the Red River of the North and the Red Lake River, encompassing 2200 acres of land. The cities of Grand Forks and East Grand Forks hired consultants to assist with the postflood planning process. The planning process culminated with the Red River of the North Greenway Final Report (Flink, 1998). The purpose of this study was to determine if the development of the Greenway addressed the objectives of the planning report. The history of the land adjacent to the rivers was reviewed to document the progression of riverfront development. Anecdotal evidence was collected, field observations were made, city council minutes were reviewed, Greenway Technical Committee members were interviewed, Greenway Technical Committee minutes were reviewed, and the Greenway Grand Forks---East Grand Forks survey results were reviewed to determine if the objectives of the Red River of the North Greenway Final Report were addressed. A cross section survey was designed by Laura Munski for this dissertation research. The survey was approved by the Greenway Technical Committee. The survey collected both quantitative and qualitative data from the community. The purpose of the survey portion of the research project was to ascertain how residents were kept informed of activities on the Greenway and what amenities residents were using on the Greenway and to solicit their comments regarding the Greenway. The results of the survey research were used in both marketing and event planning for the Greenway. The singular qualitative survey question gave respondents an opportunity to share their comments regarding the Greenway. The qualitative data analysis provided insight to the amenities and educational programs desired by respondents, their concerns regarding the Greenway, and the limitations of public knowledge regarding the Greenway. The Red River of the North Greenway Final Report (Flink, 1998) stated that the Greenway could be an excellent resource for supplementing educational curriculums. Greenways provide outdoor classrooms for both formal and informal education. The educational opportunities of other North American greenways were investigated and compared to the educational opportunities of the Greenway.

Karst hydrology of Grand Canyon, Arizona, USA  

NASA Astrophysics Data System (ADS)

SummaryCaves in Grand Canyon, Arizona, USA fall into two main categories: those formed under unconfined conditions and those formed under confined conditions. This study focuses on the hydrology and paleohydrology of the confined caves in the Redwall-Muav aquifer, where the aquifer is overlain by rocks of the Supai Group and underlain by the Bright Angel Shale. Unconfined caves are discussed only in their relation to confined caves. Discharge for confined groundwater was, as it is today, primarily from the Redwall Limestone where it has been incised by the main canyon or its tributaries and where it has converged along a structural low or fault. Descent of the potentiometric surface (or water table) over time is recorded by one ore episode and six cave episodes: (1) emplacement of Cu-U ore, (2) precipitation of iron oxide in cavities, (3) dissolution of cave passages, (4) precipitation of calcite-spar linings over cave passage walls, (5) precipitation of cave mammillary coatings, (6) minor replacement of cave wall and ceiling limestone by gypsum, and (7) deposition of subaerial speleothems. The mammillary episode records the approximate position of the water table when the incision of the canyon was at that level. Discharge toward spring points has reorganized and adjusted with respect to ongoing canyon and side-canyon incision. The dissolution of Grand Canyon confined caves was the result of the mixing of epigene waters with hypogene waters so that undersaturation with respect to calcite was achieved. The karst hydrology of Grand Canyon may be unique compared to other hypogene cave areas of the world.

The Grand Canyon: Its Youngest Rocks  

NSDL National Science Digital Library

This video segment adapted from NOVA shows a dramatic landscape created by relatively recent rock-forming activity in the Grand Canyon. Volcanic eruptions only a million years ago created the canyon's youngest rocks. In contrast with the much older Vishnu Schist formation, this younger rock has been much more susceptible to physical change. When three-hundred-meter (thousand-foot) lava dams periodically blocked the river, they were quickly eroded away and river flow restored. A background essay and list of discussion questions are included.

Grand unification and enhanced quantum gravitational effects.  

PubMed

In grand unified theories with large numbers of fields, renormalization effects significantly modify the scale at which quantum gravity becomes strong. This in turn can modify the boundary conditions for coupling constant unification, if higher dimensional operators induced by gravity are taken into consideration. We show that the generic size of, and the uncertainty in, these effects from gravity can be larger than the two-loop corrections typically considered in renormalization group analyses of unification. In some cases, gravitational effects of modest size can render unification impossible. PMID:18999739

Biological grand universality and its physical challenge  

NASA Astrophysics Data System (ADS)

Presented quantitative laws of metabolism, mortality and evolution are valid for animals from bacteria to mammals and demonstrate grand universality in biology. Its microscopic origin may be a physical and mathematical challenge. Natural evolution is accurately reduced to the continuous one, “weak” and “strong” Gould-Eldredge spurts. The discovery of writing, i.e. non-genetic, long range, collective information transfer from generation to generation with human rather than natural selection, leads to post-evolution. Technological post-evolution is exponentially rapid and may lead to the extinction of a civilization. This might resolve the Fermi-Hart paradox: if extra-terrestrial intelligence exists, why it cannot be contacted?

Local Grand Unification and String Theory  

SciTech Connect

The low energy effective action of string theory depends strongly on the process of compactification and the localization of fields in extra dimensions. Explicit string constructions towards the minimal supersymmetric standard model (MSSM) reveal interesting results leading to the concept of local grand unification. Properties of the MSSM indicate that we might live at a special location close to an orbifold fixed point rather than a generic point in Calabi-Yau moduli space. We observe an enhancement of (discrete) symmetries that have various implications for the properties of the MSSM such as proton stability as well as solutions to the flavor problem, the mu-problem and the strong CP-problem.

Aquatic macroinvertebrates of the Grand Calumet River  

USGS Publications Warehouse

The Grand Calumet River is potential habitat for a rich community of aquatic macroinvertebrates. Historical surveys of these organisms have been limited to post-industrialization of the Calumet Region; but because river habitats and conditions prior to industrialization have been described, past macroinvertebrate composition can be inferred. In the past 20 years, several surveys have been conducted in the Grand Calumet that have focused on a limited area, but when these studies are amassed the information available covers much of the river. In this paper, the aquatic macroinvertebrate communities in the river are described, and options for restoration are discussed. Many of the macroinvertebrates present are indicators of high levels of pollution, but a few pollution-sensitive species have been found. There is evidence, however, that the sediment quality has improved since the 1960's, likely due to pollution controls that have been put into place. Restoration opportunities should consider the macroinvertebrate community and the potential to improve sediment habitat without damaging the community structure.

Extension in the Rio Grande rift.  

USGS Publications Warehouse

A positive gravity anomaly along the axis of the Rio Grande rift reflects a volume of anomalous mass added at the base of the crust and intruded into the crust. Part of this volume can be associated with vertical uplift of the crust. The remainder of this anomalous volume, plus the volume of surficial graben fill, can be associated with horizontal crustal extension. The volume of crustal uplift in the Rio Grande rift is unknown, but this term can be eliminated by means of an independent equation provided by assumption of generalized isostatic equilibrium. The volume and mass equations combined provide a solution for extension of the crust in terms of the following parameters: total anomalous mass deficiency in the mantle lithosphere, total anomalous mass excess in the crust and its density contrast, total anomalous mass deficiency of surficial graben fill and its density contrast, and the volume of material eroded from the uplift. Using standard density estimates and masses determined by equivalent-source modeling of gravity profiles, I obtained 1-km extension at 37oN (Colorado-New Mexico border), 13- km extension at 35oN (Albuquerque, New Mexico), and 24-km extension at 33oN in S New Mexico.-Author

Finally, the ideas are shared with the class and recorded. It is important for students to gather information to decide whether or not this condition is hereditary. Students then watch two videos about osteoporosis. Grand Challenge Question: When you get home from school, your mother grabs you, and you rush to the hospital. Your grandmother fell and was rushed to the emergency room. The doctor tells your family your grandmother has a fractured hip, and he is referring her to an orthopedic specialist. The orthopedic doctor decides to perform a DEXA scan. The result showed her bone mineral density (BMD) was -3.3. What would be a probable diagnosis to her condition? What are some possible causes of her condition? Should her family be worried that this condition is hereditary, and if so, what are possible prevented measures they could take to prevent this from happening to them? What statistical method did you use to determine if the condition is hereditary?

Polygonal Arms in Grand Design Spirals  

NASA Astrophysics Data System (ADS)

The phenomenon of polygonal arms in grand design spiral galaxies is reviewed. The Whirlpool Nebula, Messier 51 (NGC 5194) in Canes Venatici, is taken as an archetypical example. Optical photographs, H?, UV and far-UV images, CO, 21 cm, sinchrotron emission maps, Ks-band mosaic of M 51 are used to recognize the global spiral pattern in M 51 which contains multiple straight arm segments and is presented by two polygons almost entirely. The polygons are almost identical, and the pattern has approximate twofold symmetry. The length of the straight arm segments is about the distance from the center of the disk. The segments intersect one another at the angle which is in average ? 2?/3. A brief list of galaxies with straight segments (M101 including) is given. The wave nature of the phenomenon is argued. A gasdynamical approach is discussed which implies that the formation of straight arm segments might be due to the generic stability of at shock fronts and the tendency of a slightly curved shock front to get at. A quantitative flattening criterion, based on this assumption, enables to explain the geometrical properties of the arm patterns found in M 51 and some other grand design spirals. Same considerations seem to be applicable to the ring structures that have a form of almost regular hexagons in a dozen disk galaxies.

Grand minima and maxima of solar activity: New observational constraints  

E-print Network

Using a reconstruction of sunspot numbers stretching over multiple millennia, we analyze the statistics of the occurrence of grand minima and maxima and set new observational constraints on long-term solar and stellar dynamo models. We present an updated reconstruction of sunspot number over multiple millennia, from $^{14}$C data by means of a physics-based model, using an updated model of the evolution of the solar open magnetic flux. A list of grand minima and maxima of solar activity is presented for the Holocene (since 9500 BC) and the statistics of both the length of individual events as well as the waiting time between them are analyzed. The occurrence of grand minima/maxima is driven not by long-term cyclic variability, but by a stochastic/chaotic process. The waiting time distribution of the occurrence of grand minima/maxima deviates from an exponential distribution, implying that these events tend to cluster together with long event-free periods between the clusters. Two different types of grand minima are observed: short (30--90 years) minima of Maunder type and long ($>$110 years) minima of Sp\\"orer type, implying that a deterministic behaviour of the dynamo during a grand minimum defines its length. The duration of grand maxima follows an exponential distribution, suggesting that the duration of a grand maximum is determined by a random process. These results set new observational constraints upon the long-term behaviour of the solar dynamo.

The Arctic Grand Challenge: Abrupt Climate Change  

NASA Astrophysics Data System (ADS)

Trouble in polar paradise (Science, 08/30/02), significant changes in the Arctic environment are scientifically documented (R.E. Moritz et al. ibid.). More trouble, lots more, "abrupt climate change," (R. B. Alley, et al. Science 03/28/03). R. Corell, Arctic Climate Impact Assessment team (ACIA), "If you want to see what will happen in the rest of the world 25 years from now just look what's happening in the Arctic," (Arctic Council meeting, Iceland, 08/03). What to do? Make abrupt Arctic climate change a grand challenge for the IPY-4 and beyond! Scientifically:Describe the "state" of the Arctic climate system as succinctly as possible and accept it as the point of departure.Develop a hypothesis and criteria what constitutes "abrupt climate change," in the Arctic that can be tested with observations. Observations: Bring to bear existing observations and coordinate new investments in observations through an IPY-4 scientific management committee. Make the new Barrow, Alaska, Global Climate Change Research Facility a major U.S. contribution and focal point for the IPY-4 in the U.S Arctic. Arctic populations, Native peoples: The people of the North are living already, daily, with wrenching change, encroaching on their habitats and cultures. For them "the earth is faster now," (I. Krupnik and D. Jolly, ARCUS, 2002). From a political, economic, social and entirely realistic perspective, an Arctic grand challenge without the total integration of the Native peoples in this effort cannot succeed. Therefore: Communications must be established, and the respective Native entities must be approached with the determination to create well founded, well functioning, enduring partnerships. In the U.S. Arctic, Barrow with its long history of involvement and active support of science and with the new global climate change research facility should be the focal point of choice Private industry: Resource extraction in the Arctic followed by oil and gas consumption, return the combustion products as greenhouse gases to their regions of origin. Thus multinational company operations are affected by their own activities. There is a strong, convincing case, that these industrial giants must be involved in Arctic partnerships of the grand challenge. A most instructive, very successful example is the collaboration by the chemical companies after the discovery of the polar ozone holes, followed by the replacement of the culprit chlorofluorocarbon compounds. Public relations and involvement/education: The IPY offers a unique opportunity to showcase and drive home, into homes, the seriousness of the issue, Hollywood/Madison Avenue/ NASA style, nothing else will do. Ultimately we need to be mindful that "civilizations are ephemeral compared to species. -What we need is a primer on science, clearly written and unambiguous in its meaning-a primer for anyone interested in the state of the Earth and how to survive and live well on it." (James Lovelock, Science, 08/05/98). - Let's start in the Arctic-NOW.

A liner timeline at Grand Central Sanitation  

SciTech Connect

Since the promulgation of the minimum landfill liner requirements under RCRA's Subtitle D in September 1991, nearly every operating landfill in the US that has expanded horizontally has been brought up to speed with basic environmental protection measures, i.e., liners, leachate collection groundwater monitoring, etc. For most landfills, however, these changes did not happen overnight. For more than a decade, most of the states and countless private landfills have been anticipating the advent of Subtitle D and have been upgrading outdated landfills long before the federal regulations were enforced. Grand Central Sanitation, Inc. (GCS, Pen Argyl, Pa.), for example, is a case in point. The family-run company's sanitary landfill began operation as a 52-acre, natural renovation, or earthen barrier, fill in the early 1950s and its first two fill areas, now closed, had only natural soils as a liner. Today, GCS's facility has more than doubled its permitted capacity. Its 10th disposal cell, now under construction, is triple-lined with the latest synthetic geomembranes, including high-density polyethylene (HDPE) liners, geotextiles, geonets, and leachate collection systems.

Bubbles and Black Branes in Grand Canonical Ensemble  

E-print Network

When the phase structure of the black brane in grand canonical ensemble is discussed, a new bubble phase with the same boundary data is found to exist in this structure. As such, the phase transitions among bubble, black brane and "hot flat space" are possible, therefore giving a much enriched phase structure. We argue that under some conditions, either the grand canonical ensemble itself is unstable or there are some unknown new phases.

SciTech Connect

In this research, we study Albuquerque`s water and how it may be affected by changes in the regional climate, as manifested by variations in Rio Grande water levels. To do this, we rely on the use of coupled atmospheric, runoff, and ground water models. Preliminary work on the project has focused on uncoupled simulations of the aquifer beneath Albuquerque and winter precipitation simulations of the upper Rio Grande Basin. The latter is discussed in this paper.

Chemical Contamination of the Lower Rio Grande near Laredo, TX  

NASA Astrophysics Data System (ADS)

The Rio Grande River stretches over 2000 miles from the southern Rocky Mountains in Colorado to the tip of Texas where the Rio Grande meets the Gulf of Mexico. It is the natural boundary between U.S. and Mexico from El Paso, TX, to Brownsville, TX. The communities along the border heavily rely upon the Rio Grande as a primary source of water for consumption, agricultural uses, supporting wildlife and recreation. For many years the Rio Grande has been polluted with municipal, industrial, agricultural and farming contaminants from both sides of the border. This pollution has led to the extinction or reduction of certain wildlife species as well as affecting the health of the residences along the border. Even though great strides have been made in monitoring the Rio Grande, there has been a lack of intense monitoring data collection for pollutants such as pesticides. Three sampling sites including Manadas Creek, the Rio Grande River at International Bridge I, and USGS monitoring site 08459200 off of Highway 83 were chosen. The water quality parameters focused include temperature, pH, conductivity, dissolve oxygen (DO), salinity, total dissolved solids, nutrients, metals and pesticides. Preliminary results have shown elevated concentration of total phosphorus and ortho-phosphorus in the Manadas Creek site. Organochlorinated pesticides such as heptachlor and 4, 4 DDE were detected at various concentrations at all sites and endrin aldehyde was found at Manadas Creek site. This research has provided more information on the current chemical contamination level of the Rio Grande in the Laredo area.

The Grand Tour via Geodesic Interpolation of 2-frames  

NASA Technical Reports Server (NTRS)

Grand tours are a class of methods for visualizing multivariate data, or any finite set of points in n-space. The idea is to create an animation of data projections by moving a 2-dimensional projection plane through n-space. The path of planes used in the animation is chosen so that it becomes dense, that is, it comes arbitrarily close to any plane. One of the original inspirations for the grand tour was the experience of trying to comprehend an abstract sculpture in a museum. One tends to walk around the sculpture, viewing it from many different angles. A useful class of grand tours is based on the idea of continuously interpolating an infinite sequence of randomly chosen planes. Visiting randomly (more precisely: uniformly) distributed planes guarantees denseness of the interpolating path. In computer implementations, 2-dimensional orthogonal projections are specified by two 1-dimensional projections which map to the horizontal and vertical screen dimensions, respectively. Hence, a grand tour is specified by a path of pairs of orthonormal projection vectors. This paper describes an interpolation scheme for smoothly connecting two pairs of orthonormal vectors, and thus for constructing interpolating grand tours. The scheme is optimal in the sense that connecting paths are geodesics in a natural Riemannian geometry.

Environmental Audit of the Grand Junction Projects Office  

SciTech Connect

The Grand Junction Projects Office (GJPO) is located in Mesa County, Colorado, immediately south and west of the Grand Junction city limits. The US Atomic Energy Commission (AEC) established the Colorado Raw Materials Office at the present-day Grand Junction Projects Office in 1947, to aid in the development of a viable domestic uranium industry. Activities at the site included sampling uranium concentrate; pilot-plant milling research, including testing and processing of uranium ores; and operation of a uranium mill pilot plant from 1954 to 1958. The last shipment of uranium concentrate was sent from GJPO in January, 1975. Since that time the site has been utilized to support various DOE programs, such as the former National Uranium Resource Evaluation (NURE) Program, the Uranium Mill Tailings Remedial Action Project (UMTRAP), the Surplus Facilities Management Program (SFMP), and the Technical Measurements Center (TMC). All known contamination at GJPO is believed to be the result of the past uranium milling, analyses, and storage activities. Hazards associated with the wastes impounded at GJPO include surface and ground-water contamination and potential radon and gamma-radiation exposure. This report documents the results of the Baseline Environmental Audit conducted at Grand Junction Projects Office (GJPO) located in Grand Junction, Colorado. The Grand Junction Baseline Environmental Audit was conducted from May 28 to June 12, 1991, by the Office of Environmental Audit (EH-24). This Audit evaluated environmental programs and activities at GJPO, as well as GJPO activities at the State-Owned Temporary Repository. 4 figs., 12 tabs.

Ecological potential of the Grand Calumet River basin  

USGS Publications Warehouse

The Grand Calumet River and watershed have been severely degraded by industrialization and urbanization, and yet several high-quality natural areas remain intact. The degraded condition presents numerous opportunities for pollution mitigation and ecosystem restoration. In many areas of the river and watershed, biological communities are characterized by low diversity and pollution-tolerant organisms. By establishing programs of nonnative species control, prescribed burning, sediment removal, wetland establishment and extirpated species re-introduction, the Grand Calumet can be improved to reflect some of its natural history. The dredging plan for the river presents an opportunity to coordinate simultaneous improvement and restoration plans. Possibilities for each section of the river are discussed.

Carbonaceous aerosol particles from common vegetation in the Grand Canyon  

SciTech Connect

The problem of visibility reduction in the Grand Canyon due to fine organic aerosol particles in the atmosphere has become an area of increased environmental concern. Aerosol particles can be derived from many emission sources. In this report, we focus on identifying organic aerosols derived from common vegetation in the Grand Canyon. These aerosols are expected to be significant contributors to the total atmospheric organic aerosol content. Aerosol samples from living vegetation were collected by resuspension of surface wax and resin components liberated from the leaves of vegetation common to areas of the Grand Canyon. The samples were analyzed using high-resolution gas chromatography/mass spectrometry (GC/MS). Probable identification of compounds was made by comparison of sample spectra with National Institute of Standards and Technology (NIST) mass spectral references and positive identification of compounds was made when possible by comparison with authentic standards as well as NIST references. Using these references, we have been able to positively identify the presence of n-alkane and n-alkanoic acid homolog series in the surface waxes of the vegetation sampled. Several monoterpenes, sesquiterpenes, and diterpenes were identified also as possible biogenic aerosols which may contribute to the total organic aerosol abundance leading to visibility reduction in the Grand Canyon.

This Tuesday saw the formal opening of a recent man-made addition to the rim of the Canyon that generated plenty of commentary and controversy months before it opened. The Grand Canyon Skywalk, which resembles a massive horseshoe, extends 70 feet beyond the canyon's edge. The Las Vegas developer, David Jin, created this project. Visitors to the Skywalk who pay $25 will get to look down through glass panels to the canyon floor some 4000 feet below, which could be both exhilarating and frightening, depending one one's temperament and tolerance for heights. The Hualapai Indians, who have aggressively defended the Skywalk as a form of effective economic development, approved the Skywalk and Sheri Yellowhawk who has been overseeing the project commented, "When we have so much poverty and so much unemployment, we have to do something." Other individuals and organizations have voiced strong concerns about the Skywalk, and Kieran Suckling, policy director for the Center for Biological Diversity is one of their number. In a recent interview, he commented "The tribe has repeatedly brought tacky, gross commercial ventures into the canyon, and it's inappropriate."The first link will take users to a well-written piece from Devika Bhat of the Times which comments on the opening of the Skywalk.

Water Environment Evolution along the China Grand Canal  

NASA Astrophysics Data System (ADS)

The China Grand Canal is one of the earliest canals in the world, having lasted for nearly 3000 years. Even its section canals have a rich history, such as the North-South Grand Canal that was established during the Sui Dynasty, whereas the Beijing-Hangzhou Canal was excavated during the Yuan Dynasty and the east line of the South-to-North Water Diversion. As one of the longest in the world, the China Grand Canal's total length is over 3500 kilometers. This length includes the navigable, unnavigable, and underground sections. Making the best use of situations and according to local conditions, the Chinese people harmoniously constructed the Beijing-Hangzhou Canal with nature. Tens of millions of workers took nearly 3000 years to complete the great shipping system. Navigable sections still exist for up to 900 kilometers and the volume of freight traffic is approximately 300 million tons. The canal remains the main logistical channel of the North-to-South Coal Transportation, South-to-North Water Diversion, and resources circulation. To date, China is promoting the success of heritage application. Part of these efforts is the declaration of the China Grand Canal as a World Cultural Heritage by 2014. In addition, the east route of the South-to-North Water Transfer project is planned to be navigable by 2016. The ancient Beijing-Hangzhou Grand Canal will usher in the new ecological civilization and cultural revival along the canal. This paper presents technical methods of water environment evolution research on the river system, river, and water quality along the Beijing-Hangzhou Canal through the integration of historical literature and modern remote sensing image data. The study carried out water environment investigation and analysis along the Beijing-Hangzhou canal by using ETM, SPOT image data, and GPS measurement data. Spatial and temporal evolution characteristics and regulations of the Beijing-Hangzhou Grand Canal regional water environment in the span of 3000 years were obtained. As a key national cultural relic, candidate of the world cultural heritage, and route of the South-to-North Water Diversion, the China Great Canal is a worthy subject of a study. Results presented in this paper therefore have high realistic significance.

Investigating the 2nd knee: The KASCADE-Grande experiment

Recent results from the multi-detector set-up KASCADE on measurements of cosmic rays in the energy range of the so called "first" knee (at approx. 3 PeV) indicate a distinct knee in the energy spectra of light primary cosmic rays and an increasing dominance of heavy ones towards higher energies. This leads to the expectation of knee-like features of the heavy primaries at around 100 PeV. To investigate this energy region KASCADE has recently been extended by a factor 10 in area to the new experiment KASCADE-Grande. Main results of KASCADE as well as set-up, capabilities, and status of KASCADE-Grande are presented.

It is expected to generate enough clean solar energy to power 25 percent of the building. The benefit to the public includes the economic savings from reduced operational costs for the building; an improved environmentally sustainable area in which to live and work; and increased knowledge about the use of solar energy. It will serve as a model for future energy saving applications.

Late archaic settlement systems in the northern Rio Grande  

SciTech Connect

Last year at these meetings I proposed a possible seasonal transhumance pattern for the Late Archaic in the northern Rio Grande region. This pattern involved the movement of groups from the lowland juniper-savanna grasslands in the early summer, to the upland ponderosa pindmixed conifer forests in the mid to late summer, and then back down to the piiion-juniper woodlands during the fall. The Rio Grande Valley was also used for winter habitation sites. Following on this research, I take the next step by studying the inter-assemblage variability represented in a sample of open-air sites located within each of these vegetation communities. The results indicate that there are significant differences in reduction tactics represented between valley habitation vs., upland campsites, and that these site sites are linked together by obsidian procurement patterns.

Pyrethroid Resistance in Aedes aegypti from Grand Cayman  

PubMed Central

The Grand Cayman population of Aedes aegypti is highly resistant to DDT and pyrethroid insecticides. Glutathione transferase, cytochrome P450, and esterase levels were increased in the Grand Cayman population relative to a susceptible laboratory strain, but synergist studies did not implicate elevated insecticide detoxification as a major cause of resistance. The role of target site resistance was therefore investigated. Two substitutions in the voltage-gated sodium channel were identified, V1016I in domain II, segment 6 (IIS6) (allele frequency = 0.79) and F1534C in IIIS6 (allele frequency = 0.68). The role of the F1534C mutation in conferring resistance to insecticides has not been previously established and so a tetraplex polymerase chain reaction assay was designed and used to genotype mosquitoes that had been exposed to insecticides. The F1534C mutation was strongly correlated with resistance to DDT and permethrin. PMID:20682868

Neutrino masses, grand unification, and baryon number violation  

NASA Astrophysics Data System (ADS)

If grand unification is real, searches for baryon-number violation should be included on the list of observables that may reveal information regarding the origin of neutrino masses. Making use of an effective-operator approach and assuming that nature is SU(5) invariant at very short distances, we estimate the consequences of different scenarios that lead to light Majorana neutrinos for low-energy phenomena that violate baryon number minus lepton number (B -L) by two (or more) units, including neutron-antineutron oscillations and B -L violating nucleon decays. We find that, among all possible effective theories of lepton-number violation that lead to nonzero neutrino masses, only a subset is, broadly speaking, consistent with grand unification.

Differential compaction mechanism for earth fissures near Casa Grande, Arizona.  

USGS Publications Warehouse

Precise gravity measurements indicate that earth fissures or tension cracks caused by ground-water withdrawal within a 10km2 area SE of Casa Grande are associated with relief on the buried interface between the alluvial aquifer and underlying bedrock. These relations suggest that the fissures are forming in response to localized differential compaction caused by localized variations of aquifer-system thickness. -from Authors

Origins of the 1996 controlled flood in Grand Canyon  

NASA Astrophysics Data System (ADS)

The March 1996 controlled flood in Grand Canyon resulted from a decade-long evolution in scientific thinking about the appropriate role of floods in management of the Colorado River in Grand Canyon. The flood was implemented after 5 consecutive years in which proposals to conduct a similar event were rejected; final implementation of the 1996 flood necessitated revision of the definition of the appropriate basin-wide runoff conditions that would trigger such a flood. The flood partly resulted from a multi-year effort to reform the Colorado River Storage Project Act that had culminated in passage of the Grand Canyon Protection Act in 1992. The flood itself consisted of a 4-day period of steady discharge of 227 m3/s, an 11-hr period of increasing discharge to a peak of 1274 m3/s that lasted for 7 days, a 45-hr period of recession, and a 4-day period of steady discharge at 227 m3/s. This event was partly a demonstration of the potential role of floods in regulated river management and also provided an opportunity for scientists to make measurements about physical and biological processes during flood conditions.

Field Studies of Geothermal Reservoirs Rio Grande Rift, New Mexico  

SciTech Connect

The Rio Grande rift provides an excellent field laboratory to study the nature of geothermal systems in an extensional environment. Much of the geologic complexity that is found in the Basin and Range is absent because the rift is located on cratonic crust with a thin and well-characterized Phanerozoic stratigraphy and tectonic history. On the other hand, the Neogene thermo-tectonic history of the rift has many parallels with the Basin and Range to the west. The geology of the southern Rio Grande rift is among the best characterized of any rift system in the world. Also, most geologic maps for the region are rather unique in that detailed analyses of Quaternary stratigraphic and surficial unit are added in concert with the details of bedrock geology. Pleistocene to Holocene entrenchment of the Rio Grande and tributaries unroofs the alteration signatures and permeability attributes of paleo outflow plumes and upflow zones, associated with present-day, but hidden or ''blind,'' hydrothermal systems at Rincon and San Diego Mountain.

Masses and mixings in a grand unified toy model  

SciTech Connect

The generation of the fermion mass hierarchy in the standard model of particle physics is a long-standing puzzle. The recent discoveries from neutrino physics suggest that the mixing in the lepton sector is large compared to the quark mixings. To understand this asymmetry between the quark and lepton mixings is an important aim for particle physics. In this regard, two promising approaches from the theoretical side are grand unified theories and family symmetries. In this paper we try to understand certain general features of grand unified theories with Abelian family symmetries by taking the simplest SU(5) grand unified theory as a prototype. We construct an SU(5) toy model with U(1){sub F} x Z{sub 2}{sup '} x Z{sub 2}{sup ''} x Z{sub 2}{sup '''} family symmetry that, in a natural way, duplicates the observed mass hierarchy and mixing matrices to lowest approximation. The system for generating the mass hierarchy is through a Froggatt-Nielsen type mechanism. One idea that we use in the model is that the quark and charged lepton sectors are hierarchical with small mixing angles while the light neutrino sector is democratic with larger mixing angles. We also discuss some of the difficulties in incorporating finer details into the model without making further assumptions or adding a large scalar sector.

Frequency and initiation of debris flows in Grand Canyon, Arizona  

NASA Astrophysics Data System (ADS)

Debris flows from 740 tributaries transport sediment into the Colorado River in Grand Canyon, Arizona, creating rapids that control its longitudinal profile. Debris flows mostly occur when runoff triggers failures in colluvium by a process termed "the fire hose effect." Debris flows originate from a limited number of geologic strata, almost exclusively shales or other clay-rich, fine-grained formations. Observations from 1984 through 2003 provide a 20 year record of all debris flows that reached the Colorado River in Grand Canyon, and repeat photography provides a 100 year record of debris flows from 147 tributaries. Observed frequencies are 5.1 events/year from 1984 to 2003, and historic frequencies are 5.0 events/year from 1890 to 1983. Logistic regression is used to model historic frequencies based on drainage basin parameters observed to control debris flow initiation and transport. From 5 to 7 of the 16 parameters evaluated are statistically significant, including drainage area, basin relief, and the height of and gradient below debris flow source areas, variables which reflect transport distance and potential energy. The aspect of the river channel, which at least partially reflects storm movement within the canyon, is also significant. Model results are used to calculate the probability of debris flow occurrence at the river over a century for all 740 tributaries. Owing to the variability of underlying geomorphic controls, the distribution of this probability is not uniform among tributaries of the Colorado River in Grand Canyon.

A Karst Connection model for Grand Canyon, Arizona, USA  

NASA Astrophysics Data System (ADS)

A new model for the connection of the eastern and western Grand Canyon is proposed that involves westward flow of Redwall karst aquifer water under the Kaibab arch along the steepest hydraulic gradient to discharge at a structural low in a headward-eroding protowestern Grand Canyon. A karst-aquifer hydrological connection was first established between the eastern and western Grand Canyon, then collapse, incision, and headward erosion of the canyon followed this subterranean route. This proposed model is based on what is happening today on the northern Marble Platform where the Redwall-Muav aquifer is still intact. The three sinkhole/caves Ah Hol Sah, Indian Pit, and Black Abyss provide vertical flow routes down to the Redwall karst aquifer, joining water discharging from the Kaiparowits hydrologic basin to the Colorado River along the Fence Springs system. Projecting this process back in time and spatially southward, we propose that at around 6 Ma a sinkhole or sinkholes existed at the confluence of the Colorado River with the Little Colorado River. Little Colorado River water, then flowing northward to an interior lake basin ("Glen Lake") in southern Utah, became pirated down this sinkhole(s), thus causing a reversal of drainage (barbed tributaries) in Marble Canyon. Headward erosion then proceeded up Marble and Little Colorado Canyons from the collapsing sinkhole, with Marble Canyon incision breaching Glen Lake at around 5.5 Ma. This effected the "final connection" and total integration of the Colorado River from Colorado to the Gulf of California.

Environmental assessment of facility operations at the U.S. Department of Energy Grand Junction Projects Office, Grand Junction, Colorado  

SciTech Connect

The US Department of Energy (DOE) has prepared a sitewide environmental assessment (EA) of the proposed action to continue and expand present-day activities on the DOE Grand Junction Projects Office (GJPO) facility in Grand Junction, Colorado. Because DOE-GJPO regularly proposes and conducts many different on-site activities, DOE decided to evaluate these activities in one sitewide EA rather than in multiple, activity-specific documents. On the basis of the information and analyses presented in the EA, DOE has determined that the proposed action does not constitute a major Federal action significantly affecting the quality of the human environment, as defined by the National Environmental Policy Act (NEPA) of 1969. Therefore, preparation of an environmental impact statement is not required for facility operations, and DOE is issuing this Finding of No Significant Impact (FONSI).

Fostering Scientific Literacy: Establishing Social Relevance via the Grand Challenges  

NASA Astrophysics Data System (ADS)

Numerous studies and polls suggest the general public’s understanding of science and scientific literacy remain woefully inadequate despite repeated calls for improvement over the last 150 years. This inability to improve scientific literacy significantly is a complex problem likely driven by a number of factors. However, we argue that past calls and efforts for improving scientific literacy have failed to: 1) articulate a truly meaningful justification for society to foster a scientifically literate public; 2) provide a rationale that motivates individuals of diverse backgrounds to become scientifically literate; 3) consider the impact of personal perspective, e.g. values, beliefs, attitudes, etc., on learning; and 4) offer a relevant and manageable framework in which to define scientific literacy. For instance, past calls for improving scientific literacy, e.g. the U.S. is behind the Soviets in the space race, U.S students rank below country X in math and science, etc., have lacked justification, personal motivation and a comprehensive framework for defining scientific literacy. In these cases, the primary justification for improving science education and scientific literacy was to regain international dominance in the space race or to advance global standing according to test results. These types of calls also articulate short-term goals that are rendered moot once they have been achieved. At the same time, teaching practices have commonly failed to consider the perspectives students bring to the classroom. Many STEM faculty do not address issues of personal perspective through ignorance or the desire to avoid controversial subjects, e g. evolution, climate change. We propose that the ‘grand challenges’ (e.g., energy, climate change, antibacterial resistance, water, etc.) humankind currently faces provides a compelling framework for developing courses and curricula well-suited for improving scientific literacy. A grand challenge paradigm offers four distinct advantages. First, it defines an enduring and meaningful rationale for society to invest resources in educational programs that promote scientific literacy. Second, it provides an educational context designed to engage individuals and motivate them to learn. Third, the nature of grand challenges provides mechanisms for addressing other affective barriers to individual learning that are commonly associated with controversial science-societal issues. Fourth, a grand challenge approach provides a framework to identify the concepts and processes of science a scientifically literate person should understand. Based on our experiences, we propose grand challenge science literacy (GCSL) courses or curricula are based on two primary foundations: the nature of science and the unifying concepts of science. Complementing this foundation is the science necessary to understand the grand challenge. To illustrate how science can contribute to crafting a just, equitable and sustainable solution, a GCSL course must also incorporate non-STEM perspectives, e.g. economics, politics. Finally, the personal perspectives learners bring to the classroom must be explicitly considered throughout the course.

Grande Ronde Model Watershed Program FY 1998 Habitat Projects.  

SciTech Connect

The Grande Ronde Model Watershed Program (GRMWP) is the primary entity coordinating habitat restoration on both private and public lands within the Grande Ronde Basin. The Grande Ronde Basin covers approximately 5,300 square miles, containing more than 2600 miles of fish bearing streams, in the Blue Mountains of northeast Oregon. Snake River spring chinook salmon, summer steelhead and bull trout, which are listed under the Endangered Species Act, are present in the basin. The GRMWP began coordinating restoration projects in 1994. Approximately 215 projects have been implemented through the GRMWP program as of 1998. Nine of these projects were funded in part through the Bonneville Power Administration's 1998 Columbia Basin Fish and Wildlife Program. These nine projects used a variety of methods to enhance and restore watershed conditions. In-stream work to improve fish habitat included construction of hard structures (eg. vortex rock weirs), placement of large woody material and whole trees, gravel bar treatments, and improvements to off-channel rearing habitat; 55 miles of stream were treated. Fish passage was improved at three locations by replacing or removing culverts that blocked fish. Stream riparian conditions were enhanced with exclosure fencing, vegetation planting and thinning, noxious weed control, and floodplain enhancements; 10 miles of stream were directly benefited with these riparian improvements. Four spring developments were constructed to enhance riparian and stream conditions by providing off stream livestock water sources. Nine spring developments and 1 reservoir were improved with fencing and/or piping to troughs to reduce sediment runoff and restore riparian habitat. Roads were closed or obliterated (8.5 miles) and road drainage was improved (3.4 miles) to reduce sediment delivery to streams. These nine projects cost approximately 1.3 million dollars to implement and monitor. BPA provided 41% of the funding, the remainder was cost shared by county, state, and federal agencies, private landowners, Indian tribes and natural resource interest groups.

The DOE Grand Challenge in Computational Accelerator Physics  

NASA Astrophysics Data System (ADS)

Particle accelerators are playing an increasingly important role in scientific research and in solving problems of national importance. In particular, efforts are now underway to develop accelerator-driven technologies for transmutation of radioactive waste, disposal of plutonium, energy production, and production of tritium. Next-generation spallation neutron sources based on similar technology will play a major role in materials science and biological science research. Accelerators such as the Large Hadron Collider (LHC), the Next Linear Collider (NLC), and fourth-generation light sources will have a major impact on basic and applied research. For many of these projects, high-resolution modeling far beyond that which has ever been performed by the accelerator community is required to reduce cost and technological risk, and to improve accelerator efficiency, performance, and reliability. In 1997 the U.S. Department of Energy initiated a Grand Challenge in Computational Accelerator Physics. The primary goal of the Grand Challenge is to develop a new generation of accelerator modeling tools for high performance computing platforms, and to apply them to the above-mentioned projects. The new tools will enable the simulation of problems 3 to 4 orders of magnitude larger than has ever been done before. This talk will focus on the beam dynamics effort of the Grand Challenge. Topics that will be discussed include parallel 3D space charge algorithms, high-resolution particle-in-cell codes, and the development of direct Vlasov-Poisson solvers. As an example of recent progress we will present results from a 50 million particle simulation for the accelerator production of tritium (APT) project.

Spatially adaptive grand canonical ensemble Monte Carlo simulations.  

PubMed

A spatially adaptive Monte Carlo method is introduced directly from the underlying microscopic mechanisms, which satisfies detailed balance, gives the correct noise, and describes accurately dynamic and equilibrium states for adsorption-desorption (grand canonical ensemble) processes. It enables simulations of large scales while capturing sharp gradients with molecular resolution at significantly reduced computational cost. A posteriori estimates, in the sense used in finite-elements methods, are developed for assessing errors (information loss) in coarse-graining and guiding mesh generation. PMID:15783451

Adsorption characteristics of alkanes onto carbon nanotube bundles: Grand Canonical  

E-print Network

The separation of alkanes is important for a range of applications such as oil refinement, filtration and gas separation. Carbon nanotubes, with their large surface area are highly promising for applications utilising alkane adsorption and separation. Rather than remaining isolated however, nanotubes tend to bundle together, and the adsorption properties of such bundles and subsequent potential for practical alkane separation is not yet entirely clear. For this reason, we have undertaken Grand Canonical Monte Carlo simulations in order to study the adsorption properties of alkanes on nanotube bundles. Our results show how precise control of temperature and pressure allows selective adsorption of certain alkanes, and we describe in detail the reasons behind this.

Grande Ronde Basin Fish Habitat Enhancement Project : 2000 Annual Report.  

SciTech Connect

On July 1, 1984 the Bonneville Power Administration and the Oregon Department of Fish and Wildlife entered into an agreement to initiate fish habitat enhancement work in the Joseph Creek subbasin of the Grande Ronde River Basin in northeast Oregon. In July of 1985 the Upper and Middle Grande Ronde River, and Catherine Creek subbasins were included in the intergovernmental contract, and on March 1, 1996 the Wallowa River subbasin was added. The primary goal of ''The Grande Ronde Basin Fish Habitat Enhancement Project'' is to access, create, improve, protect, and restore riparian and instream habitat for anadromous salmonids, thereby maximizing opportunities for natural fish production within the basin. This project provided for implementation of Program Measure 703 (C)(1), Action Item 4.2 of the Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program (NPPC, 1987), and continues to be implemented as offsite mitigation for mainstem fishery losses caused by the Columbia River hydro-electric system. All work conducted by the Oregon Department of Fish and Wildlife is on private lands and therefore requires that considerable time be spent developing rapport with landowners to gain acceptance of, and continued cooperation with this program throughout 10-15 year lease periods. This project calls for passive regeneration of habitat, using riparian enclosure fencing as the primary method to restore degraded streams to a normative condition. Active remediation techniques using plantings, off-site water developments, site-specific instream structures, or whole channel alterations are also utilized where applicable. Individual projects contribute to and complement ecosystem and basin-wide watershed restoration efforts that are underway by state, federal, and tribal agencies, and local watershed councils. Work undertaken during 2000 included: (1) Implementing 2 new projects in the Grande Ronde drainage, and retrofitting one old project that will protect an additional 1.3 miles of stream and 298.3 acres of habitat; (2) Conducting instream work activities in 3 streams to enhance habitat and/or restore natural channel dimensions, patterns or profiles; (3) Improving fish passage in Bear Creek to restore tributary and mainstem access; (4) Planting and seeding 6.7 stream miles with 7,100 plants and 365 lbs. of seed; (5) Establishing 18 new photopoints and retaking 229 existing photopoint pictures; (6) Monitoring stream temperatures at 12 locations on 6 streams; (7) completing riparian fence, water gap and other maintenance on 98.7 miles of project fences. Since initiation of the project in 1984 over 62 miles of anadromous fish bearing streams and 1,910 acres of habitat have been protected, enhanced and maintained.

Gravitational Collapse and Radiation of Grand Unified Theory  

E-print Network

The infinite gravitational collapse of any supermassive stars should pass through an energy scale of the grand unified theory (GUT). After nucleon-decays, the supermassive star will convert nearly all its mass into energy, and produce the radiation of GUT. It may probably explain some ultrahigh energy puzzles in astrophysics, for example, quasars and gamma-ray bursts (GRB), etc. This is similar with a process of the Big Bang Universe with a time-reversal evolution in much smaller space scale and mass scale. In this process the star seems be a true white hole.

Grand Challenges in Planetary Nebulae Studies: Binary Evolution and MHD  

E-print Network

We review work on the evolution of planetary nebulae and proto-planetaries via magneto-rotational mechanisms showing that a dynamo generated magnetic field can produce the energy and momentum needed to drive pPN and PNe outflows. Angular momentum considerations lead to the conclusion that single stars may not be capable of supporting strong fields for long times. Thus we take the working hypothesis that most PN may form via binary stars. We propose that the grand challenge for PN studies is fully understanding the diverse physical processes at work in binary late stage evolution including the development of disks, fields and outflows.

Grand Unification as a Bridge Between String Theory and Phenomenology  

NASA Astrophysics Data System (ADS)

In the first part of this paper, we explain what empirical evidence points to the need for having an effective grand unification-like symmetry possessing the symmetry SU(4)-color in 4D. If one assumes the premises of a future predictive theory including gravity — be it string/M-theory or a reincarnation — this evidence then suggests that such a theory should lead to an effective grand unification-like symmetry as above in 4D, near the string-GUT-scale, rather than the standard model symmetry. Advantages of an effective supersymmetric G(224) = SU(2)L × SU(2)R × SU(4)c or SO(10) symmetry in 4D in explaining (i) observed neutrino oscillations, (ii) baryogenesis via leptogenesis, and (iii) certain fermion mass-relations are noted. And certain distinguishing tests of a SUSY G(224) or SO(10)-framework involving CP and flavor violations (as in ? ? e?, ? ? ??, edm's of the neutron and the electron) as well as proton decay are briefly mentioned. Recalling some of the successes we have had in our understanding of nature so far, and the current difficulties of string/M-theory as regards the large multiplicity of string vacua, some comments are made on the traditional goal of understanding vis a vis the recently evolved view of landscape and anthropism.

Geomorphology of plutonium in the Northern Rio Grande  

SciTech Connect

Nearly all of the plutonium in the natural environment of the Northern Rio Grande is associated with soils and sediment, and river processes account for most of the mobility of these materials. A composite regional budget for plutonium based on multi-decadal averages for sediment and plutonium movement shows that 90 percent of the plutonium moving into the system is from atmospheric fallout. The remaining 10 percent is from releases at Los Alamos. Annual variation in plutonium flux and storage exceeds 100 percent. The contribution to the plutonium budget from Los Alamos is associated with relatively coarse sediment which often behaves as bedload in the Rio Grande. Infusion of these materials into the main stream were largest in 1951, 1952, 1957, and 1968. Because of the schedule of delivery of plutonium to Los Alamos for experimentation and weapons manufacturing, the latter two years are probably the most important. Although the Los Alamos contribution to the entire plutonium budget was relatively small, in these four critical years it constituted 71--86 percent of the plutonium in bedload immediately downstream from Otowi.

Assessing transboundary influences in the lower Rio Grande Valley  

SciTech Connect

The Lower Rio Grande Valley Transboundary Air Pollution Project (TAPP) was a US-Mexico Border XXI Program project to assess transboundary air pollution in and near Brownsville, Texas. The study used a three-site air monitoring network very close to the border to capture the direct impact of local sources and transboundary transport. Ambient data included particulate mass and elemental composition, VOCs, PAHs, pesticides, and meteorology. Also, near real-time, PM{sub 2.5} mass measurements captured potential pollutant plume events occurring over 1-h periods. Data collected were compared to screening levels and other monitoring data to assess general air pollution impacts on nearby border communities. Wind sector analyses, chemical tracer analyses, principal component analyses, and other techniques were used to assess the extent of transboundary transport of air pollutants and identify possible transboundary air pollution sources. Overall, ambient levels were comparable to or lower than other urban and rural areas in Texas and elsewhere. Movement of air pollution across the border did not appear to cause noticeable deterioration of air quality on the US side of the Lower Rio Grande Valley. Dominant southeasterly winds from the Gulf of Mexico were largely responsible for the clean air conditions in the Brownsville airshed. Few observations of pollutants exceeded effects screening levels, almost all being VOCs; these appeared to be due to local events and immediate influences, not regional phenomena or persistent transboundary plumes.

Female homicide in Rio Grande do Sul, Brazil.  

PubMed

This study aimed to assess the female homicide rate due to aggression in Rio Grande do Sul, Brazil, using this as a "proxy" of femicide. This was an ecological study which correlated the female homicide rate due to aggression in Rio Grande do Sul, according to the 35 microregions defined by the Brazilian Institute of Geography and Statistics (IBGE), with socioeconomic and demographic variables access and health indicators. Pearson's correlation test was performed with the selected variables. After this, multiple linear regressions were performed with variables with p < 0.20. The standardized average of female homicide rate due to aggression in the period from 2003 to 2007 was 3.1 obits per 100 thousand. After multiple regression analysis, the final model included male mortality due to aggression (p = 0.016), the percentage of hospital admissions for alcohol (p = 0.005) and the proportion of ill-defined deaths (p = 0.015). The model have an explanatory power of 39% (adjusted r2 = 0.391). The results are consistent with other studies and indicate a strong relationship between structural violence in society and violence against women, in addition to a higher incidence of female deaths in places with high alcohol hospitalization.

Molecular grand-canonical ensemble density functional theory  

NASA Astrophysics Data System (ADS)

The fundamental challenge of compound design, i.e. the reverse engineering of stable chemical compounds with predefined specific properties, originates in the high-dimensional and combinatorial nature of the chemical space [1] which is spanned by the grand-canonical variables (superimposed particle densities of electrons and nuclei). A rigorous description of chemical space, using a grand-canonical multi-component density functional theory framework, will be presented [2]. Specifically, a total energy density functional for molecular systems in contact with an electron and a proton bath is introduced using Lagrange multipliers which correspond to the energetic response to changes of the elementary particle densities. Results will be shown for a molecular Fukui function, for finite temperature estimates of the redox potential of ammonia, and for alchemical variation of the intermolecular energy of formic acid interacting non-covalently with 10 proton systems [2,3]. Implications for rational compound design [4] and multi-scale modeling shall be discussed.[1] P Kirkpatrick, C Ellis Nature 432 823 (2004) [2] OAvL, M E Tuckerman J Chem Phys 125 154104 (2006) [3] OAvL, M E Tuckerman submitted [4] OAvL, R Lins, U Rothlisberger Phys Rev Lett 95 153002 (2005)

Bringing Seismology's Grand Challenges to the Undergraduate Classroom  

NASA Astrophysics Data System (ADS)

The "Seismological Grand Challenges in Understanding Earth's Dynamic Systems," a community-written long-range science plan for the next decade, poses 10 questions to guide fundamental seismological research. Written in an approachable fashion suitable for policymakers, the broad questions and supporting discussion contained in this document offer an ideal framework for the development of undergraduate curricular materials. Leveraging this document, we have created a collection of inquiry-based classroom modules that utilize authentic data to modernize seismological instruction in 100 and 200 level undergraduate courses. The modules not only introduce undergraduates to the broad questions that the seismological community seeks to answer in the future but also showcase the numerous areas where modern seismological research is actively contributing to our understanding of fundamental Earth processes. To date 6 in-depth explorations that correspond to the Grand Challenges document have been developed. The specific topics for each exploration were selected to showcase modern seismological research while also covering topics commonly included in the curriculum of these introductory classes. Examples of activities that have been created and their corresponding Grand Challenge include: -A guided inquiry that introduces students to episodic tremor and slip and compares the GPS and seismic signatures of ETS with those produced from standard tectonic earthquakes (Grand Challenge "How do faults slip?"). - A laboratory exercise where students engage in b-value mapping of volcanic earthquakes to assess potential eruption hazards (How do magmas ascend and erupt?). - A module that introduce students to glacial earthquakes in Greenland and compares their frequency and spatial distribution to tectonic earthquakes (How do processes in the ocean and atmosphere interact with the solid Earth?). What is the relationship between stress and strain in the lithosphere? - An activity that examines the phenomena of earthquake triggering by distant events. (What is the relationship between stress and strain in the lithosphere?) To enhance the usefulness of these resources, all have been developed in a modular fashion which allows instructors to pick and choose some (or all) of these resources for integration in to the scope and sequence of their course. In addition to the in-depth labs, we also have created a number of mini-activities and visual material for the classroom, including think-pair-shares and lecture tutorials based on the following Grand Challenges: -What is the lithosphere-asthenosphere boundary? -How do plate boundary systems evolve? -How do temperature and composition variations control mantle and core convection? -How are Earth's internal boundaries affected by dynamics? Over the next year we will be pilot testing and refining these activities at a number of institutions, including 2- and 4-year colleges, and the materials will eventually be disseminated online and through small training workshops. Current drafts of some of the activities are available at www.tcnj.edu/~benoit/grandchallenges.

Grand Forks - East Grand Forks Urban Water Resources Study. Energy conservation and recreation appendix, public involvement appendix. Final report  

SciTech Connect

The goal of the Corps of Engineers Urban Study Program is to provide planning assistance to local interests in a variety of water resource areas. The St. Paul District conducted the Grand Forks-East Grand Forks (GF/EGF) Urban Water Resources Study which was a cooperative effort among local, state and federal agencies. Primary attention was given to flood control, water supply and wastewater management; supporting investigations addressed recreation and energy conservation. The recreation investigation consists of the leisure time analysis conducted in stage 2 of the urban study by the Heritage Conservation and Recreation Service, Department of the Interior. The leisure time analysis compared the study area's recreational needs to the available and planned facilities and identified unsatisfied needs. The thermography investigation was conducted in spring 1978 in response to the public's growing awareness of energy conservation and the Corps' desire to make the public aware of the urban study in a meaningful, useful fashion. The investigation consisted of aerial infrared photography, public displays of photographs, and distribution of information on energy saving practices. This investigation was a one-time effort with no plans for follow-up.

In 1985 the Upper and Middle Grande Ronde River, and Catherine Creek subbasins were included in the contract, and in 1996 the Wallowa River subbasin was added. The primary goal of 'The Grande Ronde Basin Fish Habitat Enhancement Project' is to create, protect, and restore riparian and instream habitat for anadromous salmonids, thereby maximizing the opportunities for natural fish production within the basin. This project originally provided for implementation of Program Measure 703 (C)(1), Action Item 4.2 of the Northwest Power Planning Council's Columbia River Basin Fish and Wildlife Program (NPPC, 1987), and continues to be implemented under revisions of the Fish and Wild Program as offsite mitigation for mainstem fishery losses caused by the Columbia River hydro-electric system. All work conducted by the Oregon Department of Fish and Wildlife and partners is on private lands and therefore requires considerable time be spent developing rapport with landowners to gain acceptance, and continued cooperation with this program throughout 10-15 year lease periods. Both passive and active restoration treatment techniques are used. Passive regeneration of habitat, using riparian exclosure fencing and alternate water sources, is the primary method to restore degraded streams when restoration can be achieved primarily through changes in management. Active restoration techniques using plantings, bioengineering, site-specific instream structures, or whole stream channel alterations are utilized when streams are more severely degraded and not likely to recover in a reasonable timeframe. Individual projects contribute to and complement ecosystem and basin-wide watershed restoration efforts that are underway by state, federal, and tribal agencies, and coordinated by the Grande Ronde Model Watershed Program (Project. No. 199202601). Work undertaken during 2008 included: (1) completing 1 new fencing project in the North Fork John Day subbasin that protects 1.82 miles of stream and 216.2 acres of habitat, and 1 fencing project in the Wallowa subbasin that protects an additional 0.59 miles of stream and 42.5 acres of habitat; (2) constructing 0.47 miles of new channel on the Wallowa river to enhance habitat, restore natural channel dimensions, pattern and profile and reconnect approximately 18 acres of floodplain and wetland habitat; (3) planting 10,084 plants along 0.5 miles of the Wallowa Riverproject; (4) establishing 34 new photopoints on 5 projects and retaking 295 existing photopoint pictures; (5) monitoring stream temperatures at 10 locations on 5 streams and conducting other monitoring activities; (6) completing riparian fence, water gap and other maintenance on 116.8 miles of project fences; and (7) completed a comprehensive project summary report to the Independent Scientific Review panel (ISRP) that provided our conclusions regarding benefits to focal species, along with management recommendations for the future. Since initiation of this program 57 individual projects have been implemented, monitoring and maintained along 84.9 miles of anadromous fish bearing streams, that protect and enhance 3,564 acres of riparian and instream habitat.

NASA Technical Reports Server (NTRS)

As part of the ERS-1 validation program, the ERS-1 Synthetic Aperture Radar (SAR) wave spectra validation experiment was carried out over the Grand Banks of Newfoundland (Canada) in Nov. 1991. The principal objective of the experiment was to obtain complete sets of wind and wave data from a variety of calibrated instruments to validate SAR measurements of ocean wave spectra. The field program activities are described and the rather complex wind and wave conditions which were observed are summarized. Spectral comparisons with ERS-1 SAR image spectra are provided. The ERS-1 SAR is shown to have measured swell and range traveling wind seas, but did not measure azimuth traveling wind seas at any time during the experiment. Results of velocity bunching forward mapping and new measurements of the relationship between wind stress and sea state are also shown.

Potential energy stored by planets and grand minima events  

NASA Astrophysics Data System (ADS)

Recently, Wolff & Patrone (2010), have developed a simple but very interesting model by which the movement of the Sun around the barycentre of the Solar system could create potential energy that could be released by flows pre-existing inside the Sun. The authors claim that it is the first mechanism showing how planetary movements can modify internal structure in the Sun that can be related to solar cycle. In this work we point out limitations of mentioned mechanism (which is based on interchange arguments), which could be inapplicable to a real star. Then, we calculate the temporal evolution of potential energy stored in zones of Sun's interior in which the potential energy could be most efficiently stored taking into account detailed barycentric Sun dynamics. We show strong variations of potential energy related to Maunder Minimum, Dalton Minimum and the maximum of Cycle 22, around 1990. We discuss briefly possible implications of this putative mechanism to solar cycle specially Grand Minima events.

The economic importance of fascioliasis in the livestock industry in the state of Rio Grande do Sul was assessed through the Federal meat inspection at major slaughter houses. Annual average rates of the livers condemned by Fasciola hepatica infection at the houses in the state have been recorded as 12-13% in cattle and 7% in sheep, respectively. Many farms in the provinces of the frontier regions of Brazil with Uruguay are contaminated with F. hepatica and acute fascioliasis with a high mortality among sheep flocks frequently occurs during the wet and cold winter season in the lowland areas of the regions. The two Lymnaeid snails, Lymnaea viatrix and L. columella are distributed in the state and act as intermediate hosts of F. hepatica. The former species, called the "mud snail", is more predominant than the latter: "pond snail". PMID:6891851

Currently, there is a number of entities seeking to determine the exact nature of the resource at the MGM site. This report concerns itself with identifying current natural gas loads within the MGM complex which could be met by geothermal should a source become available. The two principle assumptions upon which the following material is based are (1) that a source of 190/sup 0/F or higher temperature water is available and (2) all systems discussed would be installed in parallel with existing systems. That is, existing systems would remain in place providing 100 percent backup for the geothermal systems.

Magnetotelluric pilot study in the Rio Grande Rift, southwest USA  

NASA Astrophysics Data System (ADS)

A magnetotelluric (MT) pilot study consisting of approximately 25 stations distributed in and around the Rio Grande Rift of the southwest United States was carried out in the summer of 2012. Both broadband (100 Hz to 1000 s) and long-period (up to 10 000 s) MT data were collected across two profiles that run perpendicular to the rift axis near Denver, Colorado and Taos, New Mexico, respectively. Time-domain EM data was also collected at each site to account for galvanic distortion in the near-surface. The tectonic forces and rheologic properties behind the initiation and propagation of the rift are poorly understood. Surface mapping of volcanism, normal faulting and sedimentary basins reveals a narrow band of crustal deformation confined to a region in close proximity to the rift axis while geophysical results suggest that deformation is distributed across a much broader and deeper region of the lithosphere. In particular, seismic tomography shows low seismic wave speeds into the lower crust and upper mantle. The magnetotelluric technique is a well-proven passive electromagnetic method that allows for the detection of apparent resistivity at a wide range of depth scales. Complimenting the seismic results with MT data will provide important new information on the geologic and geophysical properties that control the rifting process in this low-strain rate environment. Properties to which the MT method is particular sensitive include temperature, fluid content, and mineral alteration. Preliminary results from this most recent survey are encouraging, showing good data quality up to 10 000 s. In an important precursor to full 2D modeling, the magnetotelluric phase tensor has been used to assess the dimensionality of the electrical resistivity structure at depth. This pilot study provides proof of concept for a much larger magnetotelluric experiment planned to take place in the Rio Grande Rift in 2013.

Web-based Interactive Landform Simulation Model - Grand Canyon  

NASA Astrophysics Data System (ADS)

Earth science educators need interactive tools to engage and enable students to better understand how Earth systems work over geologic time scales. The evolution of landforms is ripe for interactive, inquiry-based learning exercises because landforms exist all around us. The Web-based Interactive Landform Simulation Model - Grand Canyon (WILSIM-GC, http://serc.carleton.edu/landform/) is a continuation and upgrade of the simple cellular automata (CA) rule-based model (WILSIM-CA, http://www.niu.edu/landform/) that can be accessed from anywhere with an Internet connection. Major improvements in WILSIM-GC include adopting a physically based model and the latest Java technology. The physically based model is incorporated to illustrate the fluvial processes involved in land-sculpting pertaining to the development and evolution of one of the most famous landforms on Earth: the Grand Canyon. It is hoped that this focus on a famous and specific landscape will attract greater student interest and provide opportunities for students to learn not only how different processes interact to form the landform we observe today, but also how models and data are used together to enhance our understanding of the processes involved. The latest development in Java technology (such as Java OpenGL for access to ubiquitous fast graphics hardware, Trusted Applet for file input and output, and multithreaded ability to take advantage of modern multi-core CPUs) are incorporated into building WILSIM-GC and active, standards-aligned curricula materials guided by educational psychology theory on science learning will be developed to accompany the model. This project is funded NSF-TUES program.

Imaging the changing shoreface along South Carolina's Grand Strand  

NASA Astrophysics Data System (ADS)

The Grand Strand coastal region of South Carolina is located along Long Bay, a sediment starved embayment with few tidal inlets or fluvial sources of sediment input. The area has been the focus of ongoing coastal erosion, shoreface monitoring and geophysical/geologic framework investigations for more than a decade. We have taken a nested approach to studying shoreface morphology, looking across a range of timescales and spatial resolutions, focusing both onshore and off. Our research combines RTK-GPS beach surveys, ground-based LIDAR, beach cameras and aerial photography of the coastline, along with Chirp subbottom profiles, interferometric/multibeam bathymetry, and sidescan sonar surveys across the innershelf. Focusing on the central portion of the Grand Strand, several trends are apparent in observations across a range of time scales. In recent months, storm events and beach renourishment have influenced sediment patterns on the shoreface and innershelf. Evidence from beach profiles, shoreline surveys and sidescan sonar in the months following renourishment suggest a shift in sediment from the upper to lower shoreface and out onto the inner shelf. Pre and post surveys around Tropical Storm Hanna (September 2008) also appear to show a flux of sediment to the inner shelf. In contrast, past storm events appear to have directed sediment onshore and in many cases, the shelf appears to be the primary source of sediment to the region. Over longer time scales, we have observed seasonal variations in the geometry of the shoreface and a correlation between geologic framework and sediment distribution. Subparallel ledges along the innershelf appear to be funneling sediment offshore. Sidescan sonar and Chirp subbottom profiles suggest preservation of meandering tidal paleochannels along the innershelf that may be an important source of sediment to the region. Beach profiles over the past decade suggest a trend of lower shoreface retreat in areas with sediment cover offshore, while the shoreface may be accreting in areas flanked by nearshore hardbottom. Repeat multibeam bathymetry surveys this fall will allow us to more accurately determine the morphology of the shoreface and innershelf, examine coastal morphodynamics and assess the volume of mobile sediment.

Grand Army of the Republic Civil War Portraits  

NSDL National Science Digital Library

Shortly after the conclusion of the Civil War, Union veterans formed the Grand Army of the Republic, or the G.A.R. Through the Reconstruction era and the Gilded Age, the G.A.R. was a powerful organization that lobbied the federal government for federal and state Soldiers Homes for invalids, advocated for the creation of Memorial Day, and also provided support for soldier reunions. This digital collection created by the University of Washington Libraries peers into the faces of some of these veterans by offering up this photograph album originally created by the Stevens Post #1 of the G.A.R., based in Seattle. The album contains over 100 portraits, and visitors can browse through them at their leisure. Visitors can zoom in and out on each photograph and they can also use a number of other tools to get the best view of each photograph for their own purposes. Also, while many of the photographs have complete provenance information, some do not, and visitors are welcome to write in with any insights they might have.

Lunar and Terrestrial Planet Formation in the Grand Tack Scenario  

E-print Network

We present conclusions from a large number of N-body simulations of the giant impact phase of terrestrial planet formation. We focus on new results obtained from the recently proposed Grand Tack model, which couples the gas-driven migration of giant planets to the accretion of the terrestrial planets. The giant impact phase follows the oligarchic growth phase, which builds a bi-modal mass distribution within the disc of embryos and planetesimals. By varying the ratio of the total mass in the embryo population to the total mass in the planetesimal population and the mass of the individual embryos, we explore how different disc conditions control the final planets. The total mass ratio of embryos to planetesimals controls the timing of the last giant (Moon forming) impact and its violence. The initial embryo mass sets the size of the lunar impactor and the growth rate of Mars. After comparing our simulated outcomes with the actual orbits of the terrestrial planets (angular momentum deficit, mass concentration) ...

Grand minima of solar activity and sociodynamics of culture  

NASA Astrophysics Data System (ADS)

Indices of creative productivity introduced by C. Murrey were used to verify S. Ertel's conclusion about a global increase in creative productivity during the prolonged minimum of solar activity in 1640-1710. It was found that these indices for mathematicians, philosophers, and scientists increase in the Maunder era by factor of 1.6 in comparison with intervals of the same length before and after the minimum. A similar effect was obtained for mathematicians and philosophers for five earlier equitype minima in total (an increase by a factor of 1.9). The regularity that is revealed is confirmed by the fact that the most important achievements of high-ranking mathematicians and philosophers during the whole time period (2300 years) considered in this study fall on epochs of reduced levels of solar activity. The rise in the probability of the generation of rational ideas during grand minima is reflected also in the fact that they precede the appearance of written language and farming. Ultra-low-frequency electromagnetic fields appear to serve as a physical agent stimulating the activity of the brain's left hemisphere during the epochs of minima.

Hydrological and Meteorological Disturbances in Rio Grande Riparian Ecosystems  

NASA Astrophysics Data System (ADS)

Invasive species and ecohydrological disturbances are imperiling native riparian ecosystems. Adaptable, resilient exotic competitors including tamarisk have colonized many waterways in the western US. Alteration of the natural flow regime due to water diversions is expected to be exacerbated by climate change in this region, confounding restoration efforts. Climate change may also increase the likelihood of other disturbances, including extreme weather events (drought, floods, temperatures). We investigate how hydrological and meteorological variability impact water use by tamarisk communities that have overtaken native riparian vegetation. We have collected more than a decade of complete growing season eddy covariance evapotranspiration (ET) and water table (WT) elevation data at two sites along the Rio Grande corridor of central New Mexico, USA. Conditions have ranged from extreme drought to exceedingly wet years with extensive overbank flooding, and from record setting warm to cold temperatures. Severe to extreme droughts persisted throughout 2002 and 2003. Abundant snowpacks and wetter conditions led to extensive flooding early in the 2005 and 2008 growing seasons. Along with a return to intense drought conditions, extreme temperatures struck New Mexico in 2011. A deep freeze in early February followed by an extraordinarily late, extended hard freeze at the onset of the growing season was then succeeded by the warmest summer in the state's 117 year record. We present how water use by the replacement communities responds to droughts, flooding, and extreme temperatures, all of which are expected to increase in frequency, and speculate how these disturbances will affect native riparian ecosystems.

Young Clusters in Nearby, Grand-Design Spirals  

NASA Astrophysics Data System (ADS)

The distributions of stellar clusters in 10 nearby, grand-design spiral galaxies were studied using deep JHK-maps from HAWK-I/VLT. The properties of the cluster complexes were analyzed using (H-K)-(J-H) diagrams. Two groups of clusters can be identified where the main one is associated to old clusters with low extinction while the other, less populated, consists of very young clusters (i.e. < 10 Myr) with an average reddening around {A}_{{V}} ˜ 7m. The (J-K)-MK diagrams show two branches of clusters populated by old and young clusters, respectively. The gap between them suggests a rapid reduction of extinction in the clusters at an early evolutionary phase. Statistical tests, taking the sample sizes into account, show that the cluster distribution functions (CDF) are different in arm and inter-arm regions, for strong spiral perturbations, with the former being shifted to brighter magnitudes by at least 0.4m. Also the star formation rates in the strong arms were found to be 2-5 times higher than those in the inter-arm regions.

Analysis of the mass media coverage of the Gates Foundation grand challenges in global health initiative.  

PubMed

The Grand Challenges were launched in 2003 by the Gates Foundation and other collaborators to address the health needs of developing countries. This paper outlines the current problem with health research and development in the context of inequality as conveyed by the 90/10 divide. The paper then looks at the focus and nature of press reporting of global health issues by analysing how press articles have portrayed the Grand Challenges in Global Health initiative. Analysis of the mass media illustrates that the focus of reporting on the Grand Challenges tends to be on utilitarian themes, leaving issues related to justice and equity comparatively under-reported.

Magnétisme des cristaux de molécules à grand spin  

NASA Astrophysics Data System (ADS)

Magnetism of molecular crystals with large spins In the last decades, chemists have created magnetic molecules whose spin (typically s=10) is so high that the relaxation time of the magnetization can become macroscopic at low temperature. These new materials have novel properties which are described in detail, but in simple words in the present work. The basic principles of magnetism, such as anisotropy and exchange, are first recalled, then large spin molecules are described and situated in the world of magnetism. In the second chapter, thermally activated magnetic relaxation is studied using a master equation, the coefficients of which are evaluated from the spin-phonon interaction and Fermi's golden rule. The third chapter is devoted to the tunneling of an isolated spin in an anisotropy field, and the tunnel splitting is evaluated by simple methods. In particular, the values of the magnetic field where the tunnel splitting vanishes (“diabolic” points) are evaluated. In the fourth chapter, alternative methods based on path integrals are briefly described. In the fifth chapter, the effect of a time-dependent magnetic field is investigated, again in the case of an isolated spin. Spins are thus allowed to flip during the short time when tunneling is allowed by the magnetic field. The sixth chapter is devoted to the interaction of the spin with its environment at low temperature, when relaxation is influenced by dipole interactions with other molecular spins and with nuclear spins. In the last chapter, spin tunneling between excited states is addressed. This is a novel and important features of these materials. Finally, in six appendices, the fundamental constants and the various, usual notations are recalled as well as the correspondance between various types of magnetic fields, the Arrhenius law is derived from the master equation, the Landau-Zener-Stückelberg formula is proved, a theory of magnetic tunneling in the presence of hyperfine interactions is outlined. A last appendix contains an index. Les chimistes ont créé, dans les dernières années du vingtième siècle, des molécules magnétiques dont le spin (typiquement s=10) est suffisamment grand pour que le temps de relaxation de l'aimantation puisse devenir macroscopique à basse température. Ces nouveautés donnent lieu à des phénomènes nouveaux dont nous donnons ici une description détaillée. Nous commençons par rappeler les concepts fondamentaux du magnétisme, tels que l'anisotropie et l'échange, puis nous décrivons les molécules à grand spin et nous les situons dans le monde du magnétisme. Dans le deuxième chapitre, nous étudions la relaxation magnétique thermiquement activée, en utilisant l'équation maîtresse et en évaluant ses coefficients à partir de l'interaction spin-phonons et de la règle d'or. Le troisième chapitre est consacré à l'effet tunnel d'un spin isolé, et nous calculons l'écart tunnel par des méthodes simples. Nous obtenons en particulier les valeurs du champ magnétique où la séparation tunnel s'annule (points "diaboliques"). Dans le quatrième chapitre, nous décrivons brièvement des méthodes alternatives basées sur les intégrales sur les chemins. Dans le cinquième chapitre, nous étudions l'effet, toujours sur un spin isolé, d'un champ magnétique dépendant du temps, qui déclenche le retournement partiel des spins au moment où la valeur du champ autorise l'effet tunnel. Le sixième chapitre est consacré à l'interaction du spin avec son environnement à basse température, quand la relaxation magnétique est due aux interactions dipolaires avec les autres spins moléculaires et avec les spins nucléaires.

Geologic map of the Grand Junction Quadrangle, Mesa County, Colorado  

USGS Publications Warehouse

This 1:24,000-scale geologic map of the Grand Junction 7.5' quadrangle, in support of the USGS Western Colorado I-70 Corridor Cooperative Geologic Mapping Project, provides new interpretations of the stratigraphy, structure, and geologic hazards in the area of the junction of the Colorado River and the Gunnison River. Bedrock strata include the Upper Cretaceous Mancos Shale through the Lower Jurassic Wingate Sandstone units. Below the Mancos Shale, which floors the Grand Valley, the Upper and Lower(?)Cretaceous Dakota Formation and the Lower Cretaceous Burro Canyon Formation hold up much of the resistant northeast- dipping monocline along the northeast side of the Uncompahgre uplift. The impressive sequence of Jurassic strata below include the Brushy Basin, Salt Wash, and Tidwell Members of the Upper Jurassic Morrison Formation, the Middle Jurassic Wanakah Formation and informal 'board beds' unit and Slick Rock Member of the Entrada Formation, and the Lower Jurassic Kayenta Formation and Wingate Sandstone. The Upper Triassic Chinle Formation and Early Proterozoic meta-igneous gneiss and migmatitic meta- sedimentary rocks, which are exposed in the Colorado National Monument quadrangle to the west, do not crop out here. The monoclinal dip slope of the northeastern margin of the Uncompahgre uplift is apparently a Laramide structural feature. Unlike the southwest-dipping, high-angle reverse faults in the Proterozoic basement and s-shaped fault- propagation folds in the overlying strata found in the Colorado National Monument 7.5' quadrangle along the front of the uplift to the west, the monocline in the map area is unbroken except at two localities. One locality displays a small asymmetrical graben that drops strata to the southwest. This faulted character of the structure dies out to the northwest into an asymmetric fault-propagation fold that also drops strata to the southwest. Probably both parts of this structure are underlain by a northeast-dipping high-angle reverse fault. The other locality displays a second similar asymmetric fold. No evidence of post-Laramide tilting or uplift exists here, but the antecedent Unaweep Canyon, only 30 km to the south-southwest of the map area, provides clear evidence of Late Cenozoic, if not Pleistocene, uplift. The major geologic hazards in the area include large landslides associated with the dip-slope-underlain, smectite-rich Brushy Basin Member of the Morrison Formation and overlying Dakota and Burro Canyon Formations. Active landslides affect the southern bank of the Colorado River where undercutting by the river and smectitic clays in the Mancos trigger landslides. The Wanakah, Morrison, and Dakota Formations and the Mancos Shale create a significant hazard to houses and other structures by containing expansive smectitic clay. In addition to seasonal spring floods associated with the Colorado and Gunnison Rivers, a serious flash flood hazard associated with sudden summer thunderstorms threatens the intermittent washes that drain the dip slope of the monocline.

Grand unified theories and supersymmetry in particle physics and cosmology  

NASA Astrophysics Data System (ADS)

A review is given on the consistency checks of Grand Unified Theories (GUT), which unify the electroweak and strong nuclear forces into a single theory. Such theories predict a new kind of force, which could provide answers to several open questions in cosmology. The possible role of such a ``primeval'' force will be discussed in the framework of the Big Bang Theory. Although such a force cannot be observed directly, there are several predictions of GUT's, which can be verified at low energies. The Minimal Supersymmetric Standard Model (MSSM) distinguishes itself from other GUT's by a successful prediction of many unrelated phenomena with a minimum number of parameters. Among them: a) Unification of the couplings constants; b) Unification of the masses; c) Existence of dark matter; d) Proton decay; e) Electroweak symmetry breaking at a scale far below the unification scale. A fit of the free parameters in the MSSM to these low energy constraints predicts the masses of the as yet unobserved superpartners of the SM particles, constrains the unknown top mass to a range between 140 and 200 GeV, and requires the second order QCD coupling constant to be between 0.108 and 0.132. ``The possibility that the universe was generated from nothing is very interesting and should be further studied. A most perplexing question relating to the singularity is this: what preceded the genesis of the universe? This question appears to be absolutely methaphysical, but our experience with metaphysics tells us that metaphysical questions are sometimes given answers by physics.'' A. Linde (1982)

Lunar and terrestrial planet formation in the Grand Tack scenario.  

PubMed

We present conclusions from a large number of N-body simulations of the giant impact phase of terrestrial planet formation. We focus on new results obtained from the recently proposed Grand Tack model, which couples the gas-driven migration of giant planets to the accretion of the terrestrial planets. The giant impact phase follows the oligarchic growth phase, which builds a bi-modal mass distribution within the disc of embryos and planetesimals. By varying the ratio of the total mass in the embryo population to the total mass in the planetesimal population and the mass of the individual embryos, we explore how different disc conditions control the final planets. The total mass ratio of embryos to planetesimals controls the timing of the last giant (Moon-forming) impact and its violence. The initial embryo mass sets the size of the lunar impactor and the growth rate of Mars. After comparing our simulated outcomes with the actual orbits of the terrestrial planets (angular momentum deficit, mass concentration) and taking into account independent geochemical constraints on the mass accreted by the Earth after the Moon-forming event and on the time scale for the growth of Mars, we conclude that the protoplanetary disc at the beginning of the giant impact phase must have had most of its mass in Mars-sized embryos and only a small fraction of the total disc mass in the planetesimal population. From this, we infer that the Moon-forming event occurred between approximately 60 and approximately 130?Myr after the formation of the first solids and was caused most likely by an object with a mass similar to that of Mars.

Restoration potential of Rio Grande riparian ecosystems amid hydroclimatic challenges  

NASA Astrophysics Data System (ADS)

Hydrological processes drive the ecological functioning and sustainability of cottonwood-dominated riparian ecosystems in the arid southwestern USA. Snowmelt runoff elevates water tables (WTs) and inundates floodplains, which with favorable timing, magnitude, and duration promote cottonwood germination. Once established, these phreatophytes rely on shallow water tables. In New Mexico's middle Rio Grande (MRG) corridor, native cottonwood riparian communities are threatened by diminished flooding and deepening WTs due to river management, competitive invasive vegetation, and a persistent drought. Since 2000 we have monitored WTs and evapotranspiration (via eddy covariance flux towers) at several locations along the MRG. Conditions have ranged from extreme drought to exceedingly wet years with extensive overbank flooding. We assess the threats to and the restoration of these diverse ecosystems. Despite 2 wet years, drought has defined conditions during the first 13 years of our research (2000 - 2012). Severe to extreme drought has characterized about 40% of snowmelt periods critical to cottonwood germination and nearly half of the complete growing seasons. River flows have averaged 75% of normal and < 50% in many years. Peak snowmelt runoff during 2000 - 2012 was 36% lower and occurred 10 days earlier than the long-term mean. Our flood-prone site has been significantly inundated (> 50% of the snowmelt period) only twice, in the two wet years. The hydroclimatic regime of this region is expected to see an increase drought frequency. Thus, it is imperative to optimize restoration strategies. Suitable sites have diminished greatly as the once meandering, more freely flowing MRG has been constrained and depleted. Invasive vegetation less susceptible to the altered hydrologic regime further impact the MRG. Our long-term monitoring at various sites over a range of hydroclimatic extremes reveals attributes that can be evaluated for restoration potential. These include likelihood of flooding, timing of peak WT elevations, rate of water table decline following peaks, WT depths and variability during snowmelt and the overall growing season, and the relationship between WTs and the health of the riparian community.

Decontamination of nuclear systems at the Grand Gulf Nuclear Station  

SciTech Connect

Early in 1994 Management at the Grand Gulf Nuclear Station realized that a potential decontamination of several reactor systems was needed to maintain the commitments to the {open_quotes}As Low As Reasonably Achievable{close_quotes} (ALARA) program. There was a substantial amount of planned outage work required to repair and replace some internals in loop isolation valves and there were inspections and other outage work that needed to be accomplished as it had been postponed from previous outages because of the radiation exposure levels in and around the system equipment. Management scheduled for the procurement specification to be revised to incorporate additional boundary areas which had not been previously considered. The schedule included the period for gathering bids, awarding a contract, and reviewing the contractor`s procedures and reports and granting approval for the decontamination to proceed during the upcoming outage. In addition to the reviews required by the engineering group for overall control of the process, the plant system engineers had to prepare procedures at the system level to provide for a smooth operation to be made during the decontamination of the systems. The system engineers were required to make certain that the decontamination fluids would be contained within the systems being decontaminated and that they would not cross contaminate any other system not being decontaminated. Since these nuclear stations do not have the provisions for decontaminating these systems with using additional equipment, the equipment required is furnished by the contractor as skid mounted packaged units which can be moved into the area, set up near the system being decontaminated, and after the decontamination is completed, the skid mounted packages are removed as part of the contract. Figure 1 shows a typical setup in block diagram required to perform a reactor system decontamination. 1 fig.

Grand minima under the light of a low order dynamo model  

NASA Astrophysics Data System (ADS)

In this work we use a low order dynamo model and study under which conditions can it reproduce solar grand minima. We begin by building the phase space of a proxy for the toroidal component of the solar magnetic field and we develop a model, derived from mean field dynamo theory, that gives the time evolution of the toroidal field. This model is characterized by a non-linear oscillator whose coefficients retain most of the physics behind dynamo theory. In the derivation of the model we also include stochastic oscillations in the ? effect. We found evidences that stochastic fluctuations in ? effect can trigger grand minima episodes in this model under some considerations. We also explore other ways of creating grand minima by looking into the physical mechanisms that compose the coefficients of the oscillator. The balance between meridional circulation and magnetic diffusivity as well as the field intensification by buoyancy driven instabilities, might have a crucial role in inducing grand minima.

Quantifying Nitrogen Sources and Cycling Along the Upper Rio Grande  

NASA Astrophysics Data System (ADS)

Synoptic sampling of a 1200km reach of the Upper Rio Grande has been performed in January and August from 2000 to present. The objective of this sampling has been to develop seasonal relationships between discharge, land use, and major water quality parameters including salinity and nutrients. In general, water quality, both salinity and nutrient concentrations, degrades with distance downstream. Increased salinity is explained largely by gradual downstream increase due to evapoconcentration punctuated by localized inputs of saline groundwater. Both total dissolved nitrogen (TDN) and Dissolved Organic Carbon (DOC) concentrations gradually increase with distance downstream, however for TDN this trend is punctuated by large, localized inputs primarily from urban areas. Somewhat surprisingly, surface water draining from areas of intensive, irrigated agriculture during the growing season often had lower nutrient and DOC concentrations than the river. Increased spatial and temporal sampling of the 250km reach between Cochiti Dam and Elephant Butte Reservoir was conducted in June, July and August of 2004 to quantify the relationships between agricultural and urban land use and nutrient loading as well as nutrient sinks within the surface water, hyporheic and riparian systems. Summer 2004 data indicate that wastewater treatment plants are the largest and most consistent sources of inorganic nitrogen to the river. In both June and July there was a net removal of nitrogen from the reach as discharge decreased 26%, concentrations decreased 39%, and TDN loads decreased 56%. Interestingly, the diversion of river water for irrigated agriculture reduced discharge 25%, TDN loads 60% and concentrations 47% along the same reach before draining back to the main stem of the river suggesting that agricultural diversions were serving as a sink for nitrogen. However in August, TDN loads were higher in returning drains suggesting that agricultural systems had switched to a net source of nitrogen to the river. Possible reasons for this increase include higher rainfall in august flushing accumulated solutes coupled with increased soil available nutrients associated with the end of the growing system. Both conservative hydrologic tracers and labeled nitrogen tracer work in 2005 will be designed to identify primary controls on nitrogen removal along this reach.

Complete theory of grand unification in five dimensions  

NASA Astrophysics Data System (ADS)

A fully realistic unified theory is constructed, with SU(5) gauge symmetry and supersymmetry both broken by boundary conditions in a fifth dimension. Despite the resulting explicit breaking of SU(5) locally at a boundary of the dimension, when the size of the extra dimension is taken to be large precise predictions emerge for gauge coupling unification, ?s(MZ)=0.118+/-0.003, and for Yukawa coupling unification, mb(MZ)=3.3+/-0.2 GeV. The 5D theory is then valid over a large energy interval from the compactification scale, Mc~=1×1015 GeV, to the scale of strong coupling, Ms~=1×1017 GeV. A complete understanding of the Higgs sector of the minimal supersymmetric standard model is given, with explanations for why the Higgs triplets are heavy, why the Higgs doublets are protected from a large tree-level mass, and why the ? and B parameters are naturally generated to be of order the supersymmetry breaking scale. All sources of proton decay from operators of dimension four and five are forbidden, while a new origin for baryon number violating dimension six operators is found to be important. The exchange of the superheavy gauge boson, with a brane-localized kinetic energy interaction, leads to ?p~1034 yr, with several branching ratios determined in terms of a single mixing parameter. The theory is only realistic for an essentially unique choice of matter location in the fifth dimension: the ten-plets of the first two generations must lie in the bulk, with all other matter located on the SU(5) preserving boundary. Several aspects of flavor follow from this geometry: only the third generation possesses an SU(5) mass relation, and the lighter two generations have only small mixings with the heaviest generation except for neutrinos. The entire superpartner spectrum is predicted in terms of only two free parameters. The squark and slepton masses have sizes determined by their location in the fifth dimension, allowing a significant experimental test of the detailed structure of the extra dimension. Lepton flavor violation is found to be generically large in higher dimensional unified theories with nontrivial matter geometries, providing soft supersymmetry breaking operators are local up to the compactification scale. In our theory this forces a common location for all three neutrinos, predicting large neutrino mixing angles. Rates for ?-->e?, ?-->eee, ?-->e conversion and ?-->?? are larger in our theory than in conventional 4D supersymmetric grand unified theories, and, once superpartner masses are measured, these rates are completely determined in terms of two leptonic mixing angles. Proposed experiments probing ?-->e transitions will probe the entire interesting parameter space of our theory.

The occurrence and characteristics of grand solar minima and maxima during the Holocene epoch  

NASA Astrophysics Data System (ADS)

Observations of the Sun since 1610 AD show that the activity level of the Sun varies from the Maunder Minimum (1645-1715), when sunspots almost completely vanished from the solar surface, to the enhanced activity level since the middle of the 20th century. Maunder Minimum-like periods are believed to represent a special state of the solar dynamo and they pose a challenge for solar dynamo theory and models, in part because the current models do not agree on the frequency and nature of this phenomenon. Similarly, the models do not robustly address whether grand minima represent regular or random characteristics of the solar dynamo. Information on solar variations prior to 1610 relies on past production rates of cosmogenic nuclides, such as 10Be and 14C. Cosmogenic nuclides are produced in the atmosphere by interactions of galactic cosmic ray particles from space with atmospheric elements, such as N and O. Their production rates are inversely correlated with solar magnetic activity and the geomagnetic field intensity due to the non-linear shielding effect of the solar magnetic field and the geomagnetic dipole field. In this study, we use the IntCal13 14C and the GRIP 10Be records to calculate the solar modulation potential for the overlapping time period that approximately span the last 8000 years. Based on the solar modulation potential, we study the occurrence and characteristics of grand minima and grand maxima. In our approach, a period is only defined as a grand minimum or maximum if it can be identified as such in both reconstructions (14C and 10Be) based on Gaussian statistics. Based on this approach, we identify 19 grand minima and 15 grand maxima for the period spanning the last 8000 years. We also investigate whether the occurrence of these grand minima and grand maxima is best understood as a stochastic or non-stochastic process using waiting time distribution analysis. Furthermore, wavelet analyses of the solar modulation potential reconstructions reveal that the 22-year Hale cycle weakens during grand minimum episodes, whereas it's more pronounced during grand maximum periods. Such observations may serve as an important guide for solar dynamo models, and, in turn, improve our understanding of the processes underlying solar variability.

Evaluation of canoe surveys for anurans along the Rio Grande in Big Bend National Park, Texas  

USGS Publications Warehouse

Surveys for amphibians along large rivers pose monitoring and sampling problems. We used canoes at night to spotlight and listen for anurans along four stretches of the Rio Grande in Big Bend National Park, Texas, in 1998 and 1999. We explored temporal and spatial variation in amphibian counts and species richness and assessed relationships between amphibian counts and environmental variables, as well as amphibian-habitat associations along the banks of the Rio Grande. We documented seven anuran species, but Rio Grande leopard frogs (Rana berlandieri) accounted for 96% of the visual counts. Chorus surveys along the river detected similar or fewer numbers of species, but orders of magnitude fewer individuals compared to visual surveys. The number of species varied on average by 37% across monthly and nightly surveys. We found similar average coefficients of variation in counts of Rio Grande leopard frogs on monthly and nightly bases (CVs = 42-44%), suggesting that canoe surveys are a fairly precise technique for counts of this species. Numbers of Rio Grande leopard frogs observed were influenced by river gage levels and air and water temperatures, suggesting that surveys should be conducted under certain environmental conditions to maximize counts and maintain consistency. We found significant differences in species richness and bullfrog (Rana catesbeiana) counts among the four river stretches. Four rare anuran species were found along certain stretches but not others, which could represent either sampling error or unmeasured environmental or habitat differences among the river stretches. We found a greater association of Rio Grande leopard frogs with mud banks compared to rock or cliff (canyon) areas and with seepwillow and open areas compared to giant reed and other vegetation types. Canoe surveys appear to be a useful survey technique for anurans along the Rio Grande and may work for other large river systems as well.

Flood of July 27-31, 2006, on the Grand River near Painesville, Ohio  

USGS Publications Warehouse

Two separate weather systems produced storms resulting in more than 11 inches of rain in parts of Lake County, Ohio, on July 27-28, 2006. As a result of the storms and ensuing flooding caused by the weather systems, the counties of Lake, Geauga, and Ashtabula were declared Federal and State disaster areas, with damages estimated at $30 million and one fatality in Lake County. About 600 people were evacuated in Lake County. The U.S. Geological Survey streamflow-gaging station at Grand River near Painesville, Ohio (station 04212100), had a record peak stage of 19.35 feet (elevation, 614.94 feet), with a record peak streamflow of 35,000 cubic feet per second, and an estimated recurrence interval of approximately 500 years. This report describes the meteorological factors that resulted in severe flooding on the Grand River near Painesville from July 27 to July 31, 2006, and addresses the damages caused by the storms and flooding. Peak-stage, peak-streamflow, and recurrence-interval data are reported for the Grand River near Painesville. A plot of high-water marks is also presented for the Grand River in a reach that includes the City of Painesville, Painesville Township, the Village of Fairport Harbor, and the Village of Grand River.

Grand unification, nuclear structure and the double beta-decay  

NASA Astrophysics Data System (ADS)

Unification of the electroweak and the strong interaction prefers that the neutrino is a Majorana particle and therefore essentially identical with its own antiparticle. In such grand unified models the neutrino has also a finite mass and a slight right-handed weak interaction, since the model is left-right symmetric. These models have also left handed and right-handed vector bosons to mediate the weak interactions. If these models are correct the neutrinoless double beta-decay is feasable. Thus if one finds the neutrinoless double beta-decay one knows that the standard model can not be correct in which the neutrino is a Dirac particle and therefore different from its antiparticle. Although the neutrinoless double beta-decay has not been seen it is possible to extract from the lower limits of the lifetime against the double neutrinoless beta-decay upper limits for the effective electron-neutrino mass and for the effective mixing angle of the right-handed and the left-handed vector bosons mediating the weak interaction. One also can obtain an effective upper limit for the mass ratio of the light and the heavy vector bosons. The extraction of this physical quantities from the data is made difficult due to the fact that the weak interaction must not be diagonal in the representation of the mass matrix of the six neutrinos requested by such left-right symmetric models. A condition for obtaining reliable limits for these fundamental quantities from the measured lower limits of the half lifes of the 0??? decay are correct calculations of the nuclear matrix elements involved. These nuclear structure calculations can be tested by calculating the two neutrino double beta decay (2???) for which we have experimental data and not only lower limits as for the 0??? decay. The 2??? decay is dominated by the Gamow Teller (GT) transitions. The intermediate 1 + states in the odd-odd mass nucleus are usually calculated within the Quasi-particle Random Phase Approcimation (QRPA). Since the proton-proton and neutron-neutron pairing correlations are treated in the BCS approach particle numbers are only conserved in average for the initial |0 i+> and the final vb0 f+> states. Particle number projection is used to improve on this point. Since QRPA with the physical particle-particle interaction from the Bonn potential is close to breakdown, where the excitation energy goes to zero, higher up to third order RPA is included, by allowing anharmonicities up to three bosons in the physical wave functions. Third order RPA which is the lowest order to allow modifications of the ground state correlations affect the results appreciably. Since the intermediate states are supperpositions of proton- neutron two quasi-particle states one expects that proton-neutron pairing affects these states. From the masses of the nuclei one can extract a proton-neutron (pn) pairing gap. Due to the finite basis and the inclusion of only T = 1 (and not also T = 0, J = 1) pn-pairing the bare Brückner matrix elements of the Bonn potential yield no pn-pairing gap in most nuclei. If one fits the experimental pn-pairing gap by renormalizing the pn J ? = 0 + particle-particle Brückner matrix elements by a factor d pn ? 1.3 to 1.4 one obtains strong pn-pairing correlations, which reduce the GT strength. Since now part of the pn particle-particle correlations are already included in the BCS wave functions the 2??? strength is reduced and the dependence on the 1 + particle-particle strength parameter g pp gets weaker. In heavier nuclei like 76Ge to 76Se this dependence on g pp of the second order GT matrix elements ??GT(0 i+ ? 1 ?+ ? 0 f+) almost disappears. The upper limits derived from the neutrinoless double beta decay of 76Ge are for the effective neutrino mass < m?e >? 0.88 eV, for the left-right mixing angle < tg? >? 1.55 × 10 -8 and for the mass ratio of the light over the heavy vector boson squared < {M 12}/{M 22} > ? 1.08 × 10 -6.

US Department of Energy Grand Junction Projects Office Remedial Action Project, final report of the decontamination and decommissioning of Building 36 at the Grand Junction Projects Office Facility  

SciTech Connect

The U.S. Department of Energy (DOE) Grand Junction Projects Office (GJPO) occupies a 61.7-acre facility along the Gunnison River near Grand Junction, Colorado. This site was contaminated with uranium ore and mill tailings during uranium refining activities of the Manhattan Engineer District and during pilot milling experiments conducted for the U.S. Atomic Energy Commission`s domestic uranium procurement program. The DOE Defense Decontamination and Decommissioning Program established the GJPO Remedial Action Project to clean up and restore the facility lands, improvements, and the underlying aquifer. The site contractor for the facility, Rust Geotech, also is the remedial action contractor. Building 36 was found to be radiologically contaminated and was demolished in 1996. The soil beneath the building was remediated in accordance with identified standards and can be released for unlimited exposure and unrestricted use. This document was prepared in response to a DOE request for an individual final report for each contaminated GJPO building.

Investigation of rifting processes in the Rio Grande Rift using data from unusually large earthquake swarms  

SciTech Connect

San Acacia Swarm in the Rio Grande Rift. Because the Rio Grande rift is one of the best seismically instrumented rift zones in the world, studying its seismicity provides an exceptional opportunity to explore the active tectonic processes within continental rifts. We have been studying earthquake swarms recorded near Socorro in an effort to link seismicity directly to the rifting process. For FY94, our research has focused on the San Acacia swarm, which occurred 25 km north of Socorro, New Mexico, along the accommodation zone between the Albuquerque-Belen and Socorro basins of the central Rio Grande rift. The swarm commenced on 25 February 1983, had a magnitude 4.2 main shock on 2 March and ended on 17 March, 1983.

Vegetation and substrate properties of aeolian dune fields in the Colorado River corridor, Grand Canyon, Arizona  

USGS Publications Warehouse

This report summarizes vegetation and substrate properties of aeolian landscapes in the Colorado River corridor through Grand Canyon, Arizona, in Grand Canyon National Park. Characterizing these parameters provides a basis from which to assess future changes in this ecosystem, including the spread of nonnative plant species. Differences are apparent between aeolian dune fields that are downwind of where modern controlled flooding deposits new sandbars (modern-fluvial-sourced dune fields) and those that have received little or no new windblown sand since river regulation began in the 1960s (relict-fluvial-sourced dune fields). The most substantial difference between modern- and relict-fluvial-sourced aeolian dune fields is the greater abundance of biologic soil crust in relict dune fields. These findings can be used with similar investigations in other geomorphic settings in Grand Canyon and elsewhere in the Colorado River corridor to evaluate the health of the Colorado River ecosystem over time.

Addressing the Grand Challenge of atmospheric carbon dioxide: geologic sequestration vs. biological recycling  

PubMed Central

On February 15, 2008, the National Academy of Engineering unveiled their list of 14 Grand Challenges for Engineering. Building off of tremendous advancements in the past century, these challenges were selected for their role in assuring a sustainable existence for the rapidly increasing global community. It is no accident that the first five Challenges on the list involve the development of sustainable energy sources and management of environmental resources. While the focus of this review is to address the single Grand Challenge of "develop carbon sequestration methods", is will soon be clear that several other Challenges are intrinsically tied to it through the principles of sustainability. How does the realm of biological engineering play a role in addressing these Grand Challenges? PMID:22047501

A Miocene river in northern Arizona and its implications for the Colorado River and Grand Canyon  

USGS Publications Warehouse

The southwesterly course of the pre–late Miocene Crooked Ridge River can be traced continuously for 48 km and discontinuously for 91 km in northern Arizona. It is visible today in inverted relief. Pebbles in the river gravel came from at least as far northeast as the San Juan Mountains. The river valley was carved out of easily eroded Jurassic and Cretaceous rocks, whose debris overloaded the river with abundant detritus, possibly steepening the gradient. After the river became inactive, the regional drainage network was rearranged twice, and the Four Corners region was lowered by erosion 1–2 km. The river provides constraints on the history of the Colorado River and Grand Canyon; its continuation into lakes in Arizona or Utah is unlikely, as is integration of the Colorado River through Grand Canyon by lake spillover. The downstream course of the river was probably across the Kaibab Arch in a valley roughly coincident with the present eastern Grand Canyon.

Apatite 4He/3He thermochronometry evidence for an ancient Grand Canyon, Colorado Plateau, USA  

NASA Astrophysics Data System (ADS)

The very existence of Grand Canyon inspires questions about why canyons are carved, how drainage systems and landscapes evolve, and how these processes relate to the elevation gain of plateaus. Yet when and why Grand Canyon was carved have been extraordinarily controversial for more than 150 years. Over the last several decades, the dominant view for the origin of the canyon is one of rapid incision at 5-6 Ma, when detritus derived from the upstream reaches of the Colorado River system appeared in Grand Wash Trough at the Colorado River's western exit from the Colorado Plateau. The absence of such diagnostic deposits prior to 6 Ma has been used to argue that Grand Canyon was not yet excavated (e.g., Karlstrom et al., 2008). However, a variety of data hint at a more ancient age for part or all of the canyon, and it has been proposed that a smaller drainage basin in largely carbonate lithologies could explain the absence of pre-6 Ma Colorado River clastics in Grand Wash Trough even if a significant Grand Canyon were present. Most recently, apatite (U-Th)/He (AHe) thermochronometry data from western Grand Canyon were used to infer excavation of this area to within several hundred meters of its modern depth by ca. 70 Ma (Wernicke, 2011), an interpretation in direct conflict with the young canyon model. The unexpected implications of the initial Grand Canyon AHe work motivated the apatite 4He/3He and U-Th zonation study presented here. Apatite 4He/3He thermochronometry provides information about the spatial distribution of radiogenic 4He in an apatite crystal that can better constrain a sample's cooling history. A key premise of AHe and 4He/3He spectra interpretation is that the He kinetic model used is accurate. We first investigate whether differing 4He/3He spectra for apatites of variable AHe date, radiation damage, and U-Th zonation from eastern Grand Canyon yield mutually consistent thermal history results using the RDAAM kinetic model, which must be true if the system behaves as we anticipate. The eastern Grand Canyon 4He/3He spectra are in excellent quantitative agreement and yield a multi-phase cooling history consistent with previously published AHe data. With this validation of the radiation damage He kinetic model, we turn our attention to a similar dataset from western Grand Canyon. We find that the apatite 4He/3He and AHe data provide evidence that this segment of the canyon was excavated to within a few hundred m of modern depths by ca. 70 Ma, more than 60 m.y. earlier than generally believed. The data do not detect the strong late Tertiary cooling phase predicted by the prevailing model in which the entire canyon was carved in the last 5-6 Ma. Although the results presented here challenge the young canyon view, at present we do not see a reasonable alternative explanation for the data, and argue that any canyon model should attempt to account for these results in some viable form. No existing data refute the more ancient age for the canyon implied by these results. An ancient Grand Canyon would have important implications for the evolution of topography, landscapes, hydrology, and tectonism in the North American Cordillera.

Endangered Species Permit Number 1011 (formerly Permit No. 973) authorizes ODFW to take listed spring chinook salmon juveniles from Catherine Creek (CC), Lostine River (LR) and Grande Ronde River (GR) for research and enhancement purposes. Modification 2 of this permit authorizes ODFW to take adults for spawning and the production and release of smolts for the Captive and Conventional broodstock programs. This report satisfies the requirement that an annual report be submitted. Herein we report on activities conducted and provide cursory data analyses for the Grande Ronde spring chinook salmon Captive and Conventional broodstock projects from 1 January-31 December 2002. The Grande Ronde Basin Spring Chinook Salmon Captive Broodstock Project is designed to rapidly increase numbers of salmon in stocks that are in imminent danger of extirpation. Parr are captured in Catherine Creek, upper Grande Ronde River and Lostine River and reared to adulthood in captivity. Upon maturation, they are spawned (within stocks) and their progeny reared to smoltification before being released into the natal stream of their parents. This program is co-managed by ODFW, National Marine Fisheries Service, the Nez Perce Tribe and Confederated Tribes of the Umatilla Indian Reservation.

Site observational work plan for the UMTRA Project Site at Grand Junction, Colorado  

SciTech Connect

The U.S. Department of Energy (DOE) has prepared this initial site observational work plan (SOWP) for the Uranium Mill Tailings Remedial Action (UMTRA) Project site in Grand Junction, Colorado. This SOWP is one of the first UMTRA Ground Water Project documents developed to select a compliance strategy that meets the UMTRA ground water standards (40 CFR Part 192, as amended by 60 FR 2854) for the Grand Junction site. This SOWP applies information about the Grand Junction site to the compliance strategy selection framework developed in the UMTRA Ground Water Project draft programmatic environmental impact statement (PEIS). This risk-based, decision-making framework identifies the decision logic for selecting compliance strategies that could be used to meet the ground water standards. The DOE goal is to use the observational method to implement a cost-effective site strategy that complies with the ground water standards and protects human health and the environment. Based on an evaluation of the site characterization and risk assessment data available for the preparation of this SOWP, DOE proposes that the most likely compliance strategy for the Grand Junction site is no remediation based on the application of supplemental standards. This proposed strategy is based on a conceptual site model that indicates site-related contamination is confined to a limited-use aquifer as defined in the ground water standards.

Using Grand Challenges For Innovative Teaching in Structural Geology, Geophysics, and Tectonics  

NASA Astrophysics Data System (ADS)

An innovative approach to teaching involves using the "Big Ideas" or "Grand Challenges" of a field, as determined by the research community in that area, as the basis for classroom activities. There have been several recent efforts in the areas of structural geology, tectonics, and geophysics to determine these Grand Challenges, including the areas of seismology ("Seismological Grand Challenges in Understanding Earth's Dynamic Systems"), mineral physics ("Unlocking the Building Blocks of the Planet"), EarthScope-related science ("Unlocking the Secrets of the North American Continent: An EarthScope Science Plan for 2010-2020"), and structural geology and tectonics (at the Structural Geology and Tectonics Forum held at Williams College in June, 2012). These research community efforts produced frameworks of the essential information for their fields with the aim of guiding future research. An integral part of this, however, is training the next generation of scientists, and using these Big Ideas as the basis for course structures and activities is a powerful way to make this happen. When activities, labs, and homeworks are drawn from relevant and cutting-edge research topics, students can find the material more fascinating and engaging, and can develop a better sense of the dynamic process of scientific discovery. Many creative ideas for incorporating the Grand Challenges of structural geology, tectonics, and geophysics in the classroom were developed at a Cutting Edge workshop on "Teaching Structural Geology, Geophysics, and Tectonics in the 21st Century" held at the University of Tennessee in July, 2012.

Ground-water resources of the lower Rio Grande Valley area, Texas  

USGS Publications Warehouse

The report contains information about the occurrence, quality, and use of ground water in the Lower Rio Grande Valley area which consists of Cameron, Hidalgo, Starr, and Willacy Counties in southern Texas. The principal use of water in the area is for irrigation. The principal irrigated crops are cotton, winter vegetables, and citrus fruits. In southeastern Starr County, southern Hidalgo County, and western Cameron County, the main source of water is the Rio Grande. The greatest development of ground water in this area was after 1948 when ground water was needed to supplement water from the river. The Lower Rio Grande Valley area has four major ground-water reservoirs. Because of the uncertainty in mapping the stratigraphic units and because some of the ground-water reservoirs are composed of parts of two or more formations, three of the ground-water reservoirs have been given names in this report. The major ground-water reservoirs are: the Oakville sandstone, an important source of water for industrial use in northeastern Starr County; the Linn-Faysville ground-water reservoir, which supplies irrigation water in the Linn-Faysville area in central Hidalgo County; and the Rio Grande ground-water reservoir and the Mercedes-Sebastian shallow ground-water reservoir, both of which supply considerable irrigation water in southeastern Starr, southern Hidalgo, western Cameron, and southwestern Willacy Counties. The quality of water differs considerably from place to place in the Lower. Rio Grande Valley area. In most of the area, water is available that can be used for domestic or public supply, but it generally is slightly saline. In most of the area, the ground water is unsuitable for irrigation .particularly if used exclusively. Water of the best quality in the area is from the Rio Grande groundwater reservoir near the Rio Grande at depths of less than 75 feet in southeastern Starr County, between 50 and 250 feet in southern Hidalgo County, and between 100 and 300 feet in western Cameron County. At progressively greater distances from the Rio Grande, the ground water at these depths tends to be more mineralized. Also at some places at depths greater than those indicated, the water tends to be more mineralized. In the Linn-Faysville area the ground water from the Linn-Faysville ground-water reservoir is moderately mineralized and ranges from fair to unsuitable for irrigation. In western Cameron County, water levels in some wells tapping the Rio Grande ground-water reservoir declined about 10 feet from 1954 to 1957. In 1959 the water levels stood higher than in 1954. The water levels in most wells tapping the Linn-Faysville ground-water reservoir declined 10 feet or more from 1948 to 1958. In some wells the decline was more than 15 feet. The available information indicates that in some localities the Rio Grande ground-water reservoir may be nearly filled to capacity, and waterlogging will occur during periods of above-normal precipitation. During protracted periods of below-normal precipitation, the available water in the ground-water reservoir may be depleted. Further studies should be made in the area to correct important deficiencies in available information. A continuing program is recommended because information such as fluctuations in water levels and the amount and distribution of pumping can be obtained only on a current basis.

Using Grand Challenges to Teach Science: A Biology-Geology Collaboration  

NASA Astrophysics Data System (ADS)

Three science courses at the University of Wyoming explore the inextricable connections between science and society by centering on grand challenges. Two of these courses are introductory integrated science courses for non-majors while the third is an upper level course for majors and non-majors. Through collaboration, the authors have developed these courses to explore the grand challenges of energy, water and climate. Each course focuses on the fundamental STEM principles required for a citizen to understand each grand challenge. However, the courses also emphasize the non-STEM perspectives (e.g., economics, politics, human well-being, externalities) that underlie each grand challenge and argue that creating equitable, sustainable and just solutions to the grand challenges hinges on an understanding of STEM and non-STEM perspectives. Moreover, the authors also consider the multitude of personal perspectives individuals bring to the classroom (e.g., values, beliefs, empathy misconceptions) that influence any stakeholder's ability to engage in fruitful discussions about grand challenge solutions. Discovering Science (LIFE 1002) focuses on the grand challenges of energy and climate. Students attend three one-hour lectures, one two-hour lab and a one-hour discussion each week. Lectures emphasize the STEM and non-STEM principles underlying each grand challenge. Laboratory activities are designed to be interdisciplinary and engage students in inquiry-driven activities to reinforce concepts from lecture and to model how science is conducted. Labs also expose students to the difficulties often associated with scientific studies, the limits of science, and the inherent uncertainties associated with scientific findings. Discussion sessions provide an opportunity for students to explore the complexity of the grand challenges from STEM and non-STEM perspectives, and expose the multitude of personal perspectives an individual might harbor related to each grand challenge. Global Sustainability: Managing Earth's Resources (GEOL 1600) focuses on the energy-water climate nexus with a similar emphasis on STEM and non-STEM perspectives as LIFE 1002. Each week, there are three one hour lectures and a two hour lab. To set the stage for global and systems thinking, the concept of the Anthropocene and planetary boundaries are introduced early in the semester. Lectures focus on a variety of energy-water-climate topics and provide the content background for the labs. Labs are mini-case studies that address a variety of issues set in different global contexts, e.g. groundwater in Bangladesh, coal in China and petroleum in Saudi Arabia. Often the labs cover two weeks with one part covering science and the other economics. Unlike the other two courses, Energy: A Geological Perspective (GEOL 3650), is enrolled with half geology majors and half non-majors, representing almost every college on campus. Its organizational structure is similar to 1600. Labs focus on case studies, each lasting from 3 to 5 weeks, with each week addressing a different aspect of the same issue and social context, e.g. geology, economics, engineering, regulatory and political/social. Students, working in groups, present oral and written reports. Topics range from nuclear power and weapons in Iran to atmospheric emissions and global climate treaties.
