La feria discursiva de Juan José Arreola  

Directory of Open Access Journals (Sweden)

Full Text Available This paper is a reading of La feria, a Juan José Arreola's novel, as an eminently dialogic, heterogeneous, carnavalesque and fragmentary text that constructs meanings at the macrostructure's level. The treatment of the themes involves the formal writing structure. For this reason it's such an interesting novel. The "feria" as a religious and pagan holiday is the principal subject of this novel; but the text is a fair too, a discursive fair that includes diverse material and spiritual spheres

Full Text Available Background : The Norplant contraceptive implant has since been an accepted long-term steroidal method of contraception in Jos. It is now competing favorably with the older methods in our center. Method :A retrospective study was carried out to review the trend and characteristics of the acceptors of this relatively new contraceptive method in Jos. Results :During the 26 months period of study, May 2002 to July 2004, a total of 3,793 women accepted modern contraceptive methods within the period of study. Two hundred and sixty (260 had Norplant insertion after due counseling, constituting 6.8% of all contraceptive methods in the center. All clients were married. Their age ranged from 18-48 years with a mean of 33.05 ± 5.33 years. The women were of parity 0-8 and a mean of 3.57 ± 1.58. They were also of weight ranging from 32-95 kg with a mean of 65.78 ± 11.74. Two hundred and forty eight 95.4% of them were literate. Eighty five percent (222 of the clients had used other methods of contraception before switching over to the Norplant implants. Ten percent of the women were continuing with the Norplant after previous usage, and continuation rate was 99.2%. The commonest source of information about the method was from health workers at family planning clinics in Jos. Conclusion :Norplant contraceptive method was used by about 7% of all clients accepting modern contraceptive methods. The women accepting the method were of lower age and parity compared with that of other methods. Majority of the clients switched from other methods to Norplant.

Radioactivity effects of Jos tin mine tailings  

International Nuclear Information System (INIS)

The activity concentration of ''2''3''8U and ''2''3''2Th in Jos tin mine tailings was measured using High Purity Germanium detector (HPGe) in the Centre for Energy Research and Development, Obafemi Awolowo University, Ile-Ife. Preset counting time of 30,000s was used for each sample to avoid statistical errors. Results showed the activities varied from one site to another. The highest concentration of both ''2''3''8U and ''2''3''2Th was consistently obtained in APT1Dru sample which was collected from monazite separation site. The activity of ''2''3''8U measured range from 1.88±0.24 Bq/kg to 784.250±3.9 Bq/kg while the activity of ''2''3''2Th obtained range from 1.83± 0.16 Bq/kg to 3616.13±38.08 Bq/kg. The ratio of activity of Thorium to Uranium is greater by factor of 5 in all samples. The hot spot is APT1Dru site so also THS1 and APT1A1 can be said to hot because of high activity measured. Generally, the tailings contain both ''2''3''8U and ''2''3''2Th in high proportion which is traceable to the health concern of the inhabitants and most especially those who use the tailings for construction of dwelling and farming

Antimicrobial susceptibility pattern of Neisseria gonorrhoeae isolated at the Jos University Teaching Hospital, Jos, Central Nigeria.  

Science.gov (United States)

Widespread, inadequate and inappropriate treatment of gonococcal infections are facilitating antibiotic resistance in Jos Nigeria. We present an antimicrobial susceptibility pattern of Neisseria gonorrhoeae strains in this study. Thirty-one strains of Neisseria gonorrhoeae were isolated by inoculating swabs onto prewarmed heated blood agar and Thayer Martins medium and incubated overnight at 35 to 37 degrees C. The isolates were then screened for antimicrobial susceptibility by the disk diffusion method. About 93.6% were susceptible to azithromycin, 90.3% to ciprofloxacin, 87.1% to ceftriaxone, 80.7% and 64.3% to erythromycin and ofloxacin respectively. Less than half were each susceptible to spectinomycin (38.7%) and gentamicin (32.8%), while 12.9% and 4.6% were susceptible to tetracycline and penicillin respectively. These findings suggest that gentamicin, tetracycline and penicillin may not be recommended in this environment for treating gonococcal infections. Azithromycin, ciprofloxacin and ceftriaxone are the suggested alternatives. Prompt diagnosis, treatment and indeed continued surveillance are hereby recommended for an effective management of gonococcal infections. PMID:11705062

Genetic diversity of Mycobacterium tuberculosis Complex in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Nigeria has a high tuberculosis incidence, and genotyping studies of Mycobacterium tuberculosis Complex (MTC in the country are necessary in order to improve our understanding of the epidemic. Methods Isolates of MTC were isolated from cases of pulmonary tuberculosis in Jos, North Central region of Nigeria during 2006-2008. Drug susceptibility test (DST was performed on 77 of 111 isolates by proportion method on Lowenstein Jensen (LJ slope while genotyping of mycobacterial DNA was performed by spoligotyping. The SpolDB4 database and the model-based program 'spotclust' were used to assign isolates to families, subfamilies and variants. Results A total of 111 pulmonary isolates from consecutive tuberculosis patients in the city of Jos, Plateau State, Nigeria were spoligotyped. A total of 84 (76% of the isolates belonged to the Latin American Mediterranean (LAM family. Of these, 78 isolates were assigned to the LAM10 lineage. Among these, 66 exhibited identical spoligopatterns. Drug susceptibility profiles obtained were not consistently associated with any spoligopattern. Conclusions The dominance of few M. tuberculosis lineages suggests either a high rate of transmission, frequent import of closely related strains, or a highly conserved genotype. It remains to be confirmed whether the predominance of identical LAM10 represent an outbreak. Spoligotyping was useful to gain an overall understanding of the local TB epidemic. This study demonstrated that the incidence of TB in Jos, Nigeria may be caused by a few successful M. tuberculosis families, dominated by the LAM10 family.

Full Text Available Background : Teenage pregnancy constitutes a major health and social problem the world over. The objectives of the study were to determine the incidence of teenage pregnancy and to compare the socio-demographic characteristics, booking/delivery ratio and pregnancy outcomes of teenagers and the control in Jos University Teaching Hospital. Method : A prospective case-controlled study of the pregnancy outcome in 128 booked teenage primigravidae was compared with 633 older primigravidae aged 20-34 years (control group; who booked for antenatal care between January and December 2003 in Jos University Teaching Hospital (JUTH, Jos was conducted. Result : The study showed teenage mothers to have significantly increased proportions of Hausa/Fulani ethnicity (p=0.0000, Muslim religion (p=0.0000, lower educational status (p=0.0000, lower income group (p< 0.05, low birth weight babies (p = 0.031 and more likely to deliver outside of JUTH after booking (p = 0.036 compared to the control.

Management of the mass casualty from the 2001 Jos crisis.  

Science.gov (United States)

Background: We report our experience in the hospital management of mass casualty following the Jos civil crisis of 2001. Materials and Methods: A retrospective analysis of the records of patients managed in the Jos civil crisis of September 2001, in Plateau State, Nigeria. Information extracted included demographic data of patients, mechanisms of injury, nature and site of injury, treatment modalities and outcome of care. Results: A total of 463 crisis victims presented over a 5 day period. Out of these, the records of 389 (84.0%) were available and analyzed. There were 348 (89.5%) males and 41 females (10.5%) aged between 3 weeks and 70 years, with a median age of 26 years. Most common mechanisms of injury were gunshot in 176 patients (45.2%) and blunt injuries from clubs and sticks in 140 patients (36.0%). Debridement with or without suturing was the most common surgical procedure, performed in 128 patients (33%) followed by exploratory laparotomy in 27 (6.9%) patients. Complications were documented in 55 patients (14.1%) and there were 16 hospital deaths (4.1% mortality). Challenges included exhaustion of supplies, poor communication and security threats both within the hospital and outside. Conclusion: Most patients reaching the hospital alive had injuries that did not require lifesaving interventions. Institutional preparedness plan would enable the hospital to have an organized approach to care, with better chances of success. More effective means of containing crises should be employed to reduce the attendant casualty rate. PMID:24909466

Juan Ruiz político  

Directory of Open Access Journals (Sweden)

Full Text Available Más bien que en la vida amorosa del Arcipreste de Hita, de la que no sabemos nada, quizá tengamos que ver en el importantísimo conflicto con incidencias dinásticas virtualmente devastadoras entre María de Portugal, la mujer legítima de Alfonso XI, y Leonor de Guzmán, su concubina oficial, o, si se quiere, en el “loco amor” del rey y en el partido (el de María que –sugiero- escogió Juan Ruiz, la causa del encarcelamiento del autor del Libro de buen amor. También se comprendería que dicho contexto haya dado lugar a una obra que, tan ortodoxa en su sententia como genialmente paradójica en su littera, no tergiversa sobre los fundamentos a la vez sociales y espirituales del “buen amor” como tampoco se muestra muy propicia a la realeza tal y como la encarnaba entonces Alfonso XI de Castilla.Plutôt que dans la vie amoureuse de l’Archiprêtre de Hita, dont nous ne savons rien, peut-être faudrait-il voir dans le grave conflit aux incidences dynastiques virtuellement dévastatrices qui opposa Marie de Portugal, femme légitime d’Alphonse XI, et Aliénor de Guzmán, sa concubine officielle, ou, si l’on veut, dans le « fol amour » du roi et dans le parti (celui de Marie que choisit –je le suggère– Juan Ruiz, la cause de l’emprisonnement de l’auteur du Libro de buen amor. L’on comprendrait aussi que ce contexte ait donné lieu à une œuvre qui, aussi orthodoxe dans sa sententia que génialement paradoxale dans sa littera, ne tergiverse nullement sur les fondements sociaux et spirituels du « bon amour » mais ne se montre pas non plus favorable à une royauté telle que l’incarne alors Alphonse XI de Castille.

Un San Juan Bautista firmado por Juan Simón Gutiérrez  

Directory of Open Access Journals (Sweden)

Full Text Available El conocimiento de la pintura sevillana de la segunda mitad del siglo XVII supone uno de los grandes retos de nuestra historiografía artística. Efectivamente, el amplio abanico de discípulos e imitadores del arte de Murillo necesita una profunda revisión metodológica que sepa clarificar la nada fácil tarea de aislar las distintas personalidades que constituyen este importante grupo de artistas. En este sentido la personalidad de Juan Simón Gutiérrez (h. 1634-1724 continua siendo bastante confusa si bien con algunos interrogantes se le van atribuyendo ciertas obras que puedan responder al todavía escaso conocimiento de su estilo frente al amplio grupo de pintores pertenecientes a la escuela de Murillo.

Depression among medical outpatients with diabetes: A cross-sectional study at Jos University Teaching Hospital, Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Clinical depression is a common problem among patients who seek medical care, and diabetic patients with comorbid depression tend to have higher health care cost. A dearth of literature exists on depression among diabetics in Nigeria. The objectives of the study were to determine the prevalence of depression among diabetic patients and to determine the sociodemographic correlates of depression among diabetics. Methods: A cross-sectional descriptive study was conducted between December 2005 and April 2006 among patients who attend the diabetes clinic of Jos University Teaching Hospital (JUTH with a laboratory and clinical evidence of diabetes mellitus. A semi-structured questionnaire was used to record the sociodemographic data of each consecutive patient followed by an interview by psychiatrists using the depression module of the Structured Clinical Interview for DSM-I V axis I disorder (SCID. Subsequently, the Hamilton Rating Scale for Depression (HDRS was used to determine the severity of symptoms among subjects diagnosed with depression according to DSM-I V criteria. Results: Thirty-one of the 160 subjects fulfilled the DSM-IV criteria for the diagnosis of a major depressive episode giving a 1-year prevalence rate of 19.4%. Depression was significantly correlated with sex (P=0.001 with a female-to-male ratio of 3:1 and was also significantly associated with unmarried diabetics (P=0.002 and those who had a poor relationship with their partners (P=0.04. No significant association was found between depression and the respondents? age (P=0.216, educational qualifications (P=0.268, employment status (P=0.84, place of residence (P=0.80, household composition (P=0.77, and monthly income (P=0.110. Conclusion: Depression is a common psychiatric disorder among diabetic subjects in this environment. It was suggested that diabetic patients be screened for depression to allow for early detection and treatment.

Wind speed distribution and performance of some selected wind turbines in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available The wind speed data of Jos have been shown to be either gamma or normally distributed. The wind is available and could be used for both residential and large scale power generation. At respective hub heights of 15m and 100m, at least 23% and 40% of Iskra AT5-1 and Micon NM 82 wind turbines installed capacities can averagely be generated respectively. A Micon NM 82 installed at a height of 100m in Jos can service about 210 homes each consuming at most 3kW of electrical power. The site is therefore good and the performance of the best two wind turbines attractive for investors.

Measurement of alpha particle, beta particle and gamma radiation in mine site around Jos metropolis  

International Nuclear Information System (INIS)

Monitoring of alpha particle, beta particle and gamma radiation were carried out in mine sites around Jos metropolis using the G.M. counter, scintillometer and the PUG-7A survey meters. These instruments were used to monitor and measure the radiation levels in 15 mining sites in Jos metropolis. The highest radiation levels was found to be 12.8 mSv/yr which is less than internationally allowed maximum permissible level of 20 mSv/yr as recommended by the International Commission on Radiological Protection (ICRP). Also the individual radiation levels were found to be 1.3±0.05 mSv/yr for alpha, 0.11±0.01 mSv/yr for beta and 5.7±0.35 mSv/yr for gamma. This means that the mining sites visited are operating within the safety limits

Social factors affecting seasonal variation in bovine trypanosomiasis on the Jos Plateau, Nigeria  

Science.gov (United States)

Background African Animal Trypanosomiasis (AAT) is a widespread disease of livestock in Nigeria and presents a major constraint to rural economic development. The Jos Plateau was considered free from tsetse flies and the trypanosomes they transmit due to its high altitude and this trypanosomiasis free status attracted large numbers of cattle-keeping pastoralists to the area. The Jos Plateau now plays a major role in the national cattle industry in Nigeria, accommodating approximately 7% of the national herd, supporting 300,000 pastoralists and over one million cattle. During the past two decades tsetse flies have invaded the Jos Plateau and animal trypanosomiasis has become a significant problem for livestock keepers. Here we investigate the epidemiology of trypanosomiasis as a re-emerging disease on the Plateau, examining the social factors that influence prevalence and seasonal variation of bovine trypanosomiasis. Methods In 2008 a longitudinal two-stage cluster survey was undertaken on the Jos Plateau. Cattle were sampled in the dry, early wet and late wet seasons. Parasite identification was undertaken using species-specific polymerase chain reactions to determine the prevalence and distribution of bovine trypanosomiasis. Participatory rural appraisal was also conducted to determine knowledge, attitudes and practices concerning animal husbandry and disease control. Results Significant seasonal variation between the dry season and late wet season was recorded across the Jos Plateau, consistent with expected variation in tsetse populations. However, marked seasonal variations were also observed at village level to create 3 distinct groups: Group 1 in which 50% of villages followed the general pattern of low prevalence in the dry season and high prevalence in the wet season; Group 2 in which 16.7% of villages showed no seasonal variation and Group 3 in which 33.3% of villages showed greater disease prevalence in the dry season than in the wet season. Conclusions There was high seasonal variation at the village level determined by management as well as climatic factors. The growing influence of management factors on the epidemiology of trypanosomiasis highlights the impact of recent changes in land use and natural resource competition on animal husbandry decisions in the extensive pastoral production system.

Science.gov (United States)

As a part of the Special Funds Collection of the Jalisco's State Public Library ``Juan Jos'e Arreola'' is a physics course manuscript attributed to Francisco Javier Clavigero s.j. (1731-1787), teacher at the Jesuit Colegio de Santo Tom'as (a college-level institution in Guadalajara before the university opening), inside of the vellum bounded volume is a unbounded folio containing instructions on how to build a thermometer. In this work are discussed some evidences of the belonging of such folio to the manuscript in spite of their differences (it is written in Spanish not in Latin as the whole), we also describe the process to construct the thermometer and how could be the experimental part of the physics course. Also is briefly exposed the importance of the educational role of Clavigero as a builder of the concept of mexicanity.

Radiological measurement of some nuclides in processed mine tailings in Jos  

International Nuclear Information System (INIS)

The Jos plateau is situated in the central part of northern Nigeria; on a rugged terrain of low lands at the edge of the plateau surface. It is the principal centre of tin and columbite mineralization, which forms the focal area of younger granites. The mine tailings are associated with radioactive minerals as impurities such as monazite, zircon among others. These minerals are very radioactive and cause hazards to human health during mining and milling. A total of thirty-one tailings (31) samples from a mining and processing site in Jos were collected at different directions and distance and analyzed for ''4''0K, ''2''2''6Ra and ''2''3''2Th concentrations using NaI(TI) detector, in order to estimate the level of their radiological impact to the public. Samples D8 of ''2''3''2Th, B2 of ''2''2''6Ra D8 of ''4''0K show high concentrations in the composite tailings. D6 of ''2''3''2Th, D5 of ''2''2''6Ra and C7 of ''4''0K show low concentrations in the composite tailings. The highest and lowest concentrations are in D8 of ''2''3''2Th (27930.0 Bq/kg) and D5 of ''2''2''6Ra (364.9 Bq/kg). All concentrations range from (364.9 Bq/kg - 27930.0 Bq/kg) in the tailings. Considering ''2''2''6Ra, ''4''0K and ''2''3''2Th concentrations, it could be said that the major source of radiation in Jos, Plateau State is thorite

Multidrug Resistant Pasteurella multocida Strains Isolated from Chickens with Cases of Fowl Cholera in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Antibiotic resistance is often encountered despite multiple antibiotics being used for the treatment of fowl cholera in Jos. This study was conducted to determine the antibiotic resistant profile of Pasteurella multocida isolated from chickens in Jos. A total of 2000 samples consisting of bone marrow, heart, liver, lung and spleen (400 each were collected from 400 clinically sick chickens between November, 2010 and October, 2011 for the isolation of P. multocida. Swab from each sample was cultured on 7% defibrinated sheep blood, MacConkey and casein sucrose yeast agar. Presumptive colonies of P. multocida were subjected to biochemical characterization. Isolates identified by biochemical tests were further subjected to Microbact GNB 24E test. Disk diffusion method was employed to test the sensitivity of all the twelve P. multocida isolates confirmed by biochemical and Microbact GNB 24E test. The twelve pure isolates of P. multocida were tested for their sensitivity against fifteen different antibiotics. Drug sensitivity test conducted on P. multocida isolates showed that some of the isolates were resistant to penicillin 11 (73%, microlides 9 (60%, sulfanomides 8 (53.3%, cephalosporins 3 (20% and other new groups of antibiotics 4 (27%. High resistance of P. multocida was recorded for ampicillin (91.7% followed by amoxicillin/clavulanic acid (83.3%, trimethoprim/sulfamethoxazole (66.7%, erythromycin and anicillin (58.3% each, while tylosin was (33.3%. This study revealed that there is an emergence of multidrug resistance in some P. multocida strains among chickens in Jos, Nigeria. It is therefore recommended that antibiotic sensitivity test should be incorporated on a routine bases as part of measure to control fowl cholera and minimize the emergence of P. multocida resistance.

Full Text Available Residential segregation could be regarded as a process whereby two or more distinct communities who formerly lived together separate from one another due to many factors. Residential segregation is not only applicable to small communities but rather to a larger region. As a result of the ongoing civil unrest that engulfed the city of Jos, there has been a process of residential mobility and relocation among people of different faith. The paper is aimed at examining the implication of intangible location attributes on residential mobility, segregation and relocation in Jos town. Stratified random sampling technique was employed in order to come up with the sample needed to conduct the research. The data needed for the research were retrieved through structured, semi-structured and unstructured interview method of data collection. A qualitative method and approach of data analysis through the use of a thematic network analysis was incorporated in order to analyse the data gotten from the interview survey. The results uncovered that residential segregation in the study area leads to change in the residential pattern of Jos town. The variations and trends in the sales and rental value of residential properties were greatly affected as a result of the persisting residential segregation. The research concludes that residential segregation has a great implication on land and landed property value as variations in the values of residential properties is noticeable. There is a need for those in authority to take a decisive action in order to overcome and halt the persisting mobility and relocation in the study area.

Serological Survey Of Salmonella gallinarum Antibody In Chickens Around Jos, Plateau State, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available A serological survey of the prevalence of antibodies to Salmonella gallinarum among chickens under two different management systems around Jos, Plateau State, Nigeria was carried out using the standard plate agglutination test. The objective of this study was to determine serologically the prevalence of antibodies against Salmonella gallinarum among apparently healthy chickens around Jos. A total of 700 serum samples made up of 450 exotic and 250 local breed of chickens were used for this study with 37.9% seropositvity. In the free range system (19.3% of the flocks sampled were seropositive for Salmonella gallinarium antibodies while in the semi intensive, 18.6% of the flock tested positive. The serum agglutination test (SAT was adapted to the microtitre format used to determine somatic and flagella titres. The antigen used for this study was specific for S. gallinarum, hence differentiation between species infection was assessed in this study. Perhaps the most feasible way to eradicate the disease is to encourage farmers (both small and large scale to break the disease cycle at their levels by embarking on prompt and regular vaccination programmes. It is thus concluded that Salmonella gallinarum (fowl typhoid is present in the area investigated. Fowl typhoid may continue to have a negative effect on the economy of poultry production in Nigeria if not controlled. A statistical analysis was precluded due to inadequate data sets.

Multiple drug resistant strains of Shigella isolated in Jos, central Nigeria.  

Science.gov (United States)

The objective of this study is to highlight the alarming rise in antimicrobial resistance among Shigella species in Jos, Plateau State. Stool samples of eight hundred and ten patients who presented at the Jos University Teaching Hospital with diarrhoea/dysentery were analysed using standard bacteriological techniques. The antimicrobial susceptibility of the isolates were determined. 25 Shigella species were isolated representing 3.1% isolation rate. The male to female ratio is 1.3:1, children aged 0-10 years constituted 16(64%) of the cases. Shigella flexneri (48%) was the most common sero-group. This was followed by S. boydii (24%), then S. sonnei (20%), and S. dysenteriae (8%). Most strains of shigella species were resistant to Ampicillin (96.0%). Chloramphenicol (96.0%), Cotrimoxazole (88%), Nalidixic acid (84%) and Tetracycline (75%). All strains were found to be sensitive to Ciprofloxacin. The drugs of choice in the treatment of Shigella infection in this environment should be Ciprofloxacin and Ofloxacin. Gentamicin was the third drug of choice its use is limited since the infection is not systemic. To avoid continuous abuse of antibiotics in our country there should be an effective legislation by the government to control the indiscriminate purchase of antibiotics. PMID:14692056

Prevalence of cryptosporidium infection among undernourished children in Jos, Central Nigeria.  

Science.gov (United States)

This prospective study aimed at determining the prevalence data of Cryptosporidium infection in undernourished children, its seasonality and its relative frequency in diarrhoeic stool in Jos, Central Nigeria. One hundred and seventy each of undernourished and well nourished children aged 0-5 years were recruited into the study. Stool samples and clinical data were obtained using questionnaires. Results were analysed using Chi-square test. The prevalence of the infection was found to be 4.8% and all infections occurred in diarrhoeic stool. No infection with this pathogen was recorded in the well-nourished group. There was a defined seasonality of the infection. The high prevalence suggests the importance of introducing routine screening of this group of patients for cryptosporidium infection to facilitate their management. PMID:14567041

Quarter of a century of female sterilization in Jos, Central Nigeria.  

Science.gov (United States)

The study was to assess the types and trend of female sterilization between January 1985 and December 2009 (25 years) in Jos, Central Nigeria. There were 25,313 new acceptors of modern contraceptive methods out of which 4,951 (19.6%) were female sterilizations. Minilaparotomy was the commonest method of female sterilization. Local anaesthesia was the commonest anaesthetic utilized. The women were mostly women of relatively older age, grandmultiparous and with large family size. The women were of mean of 38.4 years, and 60% had more than 5 children at the time of sterilization. Interval sterilization constituted 78.5% of the female sterilizations. The acceptance of female sterilization, however, has declined over the years, as acceptance of the long acting contraceptive implants increases. Female sterilization by minilaparotomy under local anaesthesia was found to be feasible, cost effective and acceptable by majority of clients, and recommended for integration into minor gynaecological procedures in our institutions.

Road profiling of traffic accidents in Jos, Nigeria, 1995-1999.  

Science.gov (United States)

Road traffic accident data in Nigeria generally lack exact coordinate information. Accident analysis is, therefore, restricted to aggregate data on trends, magnitude and temporal dimensions. This article addresses the road accident problem in Jos between 1995 and 1999 through a road profiling approach. Results show that four gateway routes, seven multi-lane roadways (including two gateway routes) and seven road intersections accounted for 84% of all traffic accidents, 84% of injured casualties and 88% of fatalities. This approach allows for quantification of impacts of controlling for accidents by deliberate profiling of roads for close monitoring and policing. For example, reducing accident counts and fatalities by 50% each on gateway routes will amount to approximately 35 and 40% reduction in accident and fatality counts, respectively. Countermeasures must consider these roadways and intersections as important inputs in their accidents and casualty reduction targets. PMID:19941215

Full Text Available Water used for domestic purposes is ideally required to be free from contaminants. Various contaminants have frequently affected the quality of such water. Water samples were obtained from 150 sources including 72 wells, 60 streams, 17 taps, and one borehole, randomly selected from five residential areas in Jos, Nigeria. Structured questionnaires and one-to- one interview was used to obtain information on features of location and use of facilities in each area. Eighty (53.3% water sources were contaminated, predominantly wells (70.8%. The locations (identified in code with the highest number of contaminated sources were AGO (60.0%, GBU (56.7% and FGD (56.7%. AGD and FGD also had the highest ratio of households to one water source (25:1. Eighty- two fungi were isolated, predominantly Candida tropicalis (23.2%, Candida lipolytica (10.9% and Rhodotorula sp (9.7%. Candida lipolytica was the highest (42.9% contaminant in tap water. Rhodotorula sp was found in all types of water sources sampled. Type of water source had a significant effect (P<0.05 on the presence of some fungi in the water. The residential area (Location had a significant effect on contamination of water sources by some yeasts. Water sources for domestic use in Jos are contaminated by yeasts and yeast-like fungi. Frequency of use, exposure of the facility to dirt, and contaminations of surroundings contribute to the occurrence of fungi in water sources and, by implication, the prevalence of fungal infections.

Directory of Open Access Journals (Sweden)

Full Text Available Adaobi Ifeoma Ekwempu1, Zwalnan S Wuyep2, Bitrus Longkem3 1Department of Medical Laboratory Sciences, University of Jos, Jos, Plateau State, 2Hospital Management Board, Jos, Plateau State, 3Department of Chemical Pathology, Jos University Teaching Hospital, Jos, Plateau State, Nigeria Purpose: This study was designed to determine the blood glucose level of healthy adolescents living in the southern region of Plateau State in northern Nigeria. Design: The study screened apparently healthy adolescents to identify individuals at high risk of developing diabetes mellitus. Methods and materials: Individuals who were confirmed healthy and not on any form of medication were enrolled in the study after the administration of a questionnaire which ruled out any form of aliment such as fever, gastroenteritis, and malaria. The serum glucose level was quantified using the glucose oxidase reagent. Data generated were analyzed using Excel 2007 (Microsoft®, Redmond, WA and Student’s t-test for an established normal range. Results: The age distribution showed that those aged 14–16 years had a mean serum glucose level of 4.8 ± 1.11 mmol/L, while in those aged 17–19 years it was 4.9 ± 1.115 mmol/L, with a standard error of the mean of 0.17 and 0.15, respectively. The mean glucose level, weight, and height of the enrollees were 4.8 ± 1.12 mmol/L, 56.6 ± 6.20 kg, and 1.6 ± 0.009 m, respectively. The mean serum glucose of those from the Berom tribe and other tribes was 4.9 ± 1.21 mmol/L and 4.8 ± 1.15 mmol/L, respectively. Analysis of the mean glucose level with respect to sex, age, tribe, weight, and height of the established normal mean resulted in a P value of < 0.05, which was not significant. Conclusion: There was no significant difference in the serum glucose level of enrolled subjects. It was also observed that there was no significant difference between the glucose level based on the different tribes, sex, weight, and height of all enrolled subjects. Since glucose is involved with various body metabolic processes and is also an analyte of interest in diabetes mellitus, screening of adolescents would reduce the incidence of the disease.

Sero-survey of rubella IgM antibodies among children in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Sero-survey of rubella IgM antibodies was carried out among children aged 0-10 years in Jos, Nigeria. Blood samples were collected from the subjects and sera extracted. Of the 93(100% assayed for the rubella IgM antibody, 42(45.2% were seropositive for rubella IgM antibody while 51(54.8% were seronegative. A breakdown of the seropositive subjects reveals that 14(15.1% of the infected children were males while 28(30.1% were females. Those subjects within the age groups of 1-2, 3-4 and 5-6 years had the highest prevalence of 8(8.6% followed by those within the age groups of 7-8, 9-10 years with 7(7.5%. Blood transfusion as a risk factor did not show any significant influence on the status of the subjects. The demographic data of the mothers of the subjects were also linked with the seropositivity of the children.

A Survey of Chick Mortality at Hatching in three Selected Hatcheries in Jos, Central Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available A questionnaire-based survey was conducted to investigate chick mortality at hatching in three commercial hatcheries in and around Jos, central Nigeria. Mortality was defined as the sum of dead chicks, dead-in-shell embryos and culls due to various other reasons. There was a large variation in culling rates due to poor hatching. The major reasons for culling were dead-in-shell embryos, weak chicks, dead chicks, omphalitis and physical abnormalities such as incomplete feathering, weak limbs, distorted beaks and wetness. There was no significant correlation between the age of breeding flock and percentage of culls indicating that culling rate was not strongly influenced by the age of breeding flock. Although, factors contributing to poor hatching include management and incubation failures, the most probable cause of abnormalities, weak chicks and omphalitis are diseased breeder flocks or poor hygiene and sanitation in hatchery operations. Two of the hatcheries used a combination of formaldehyde and iodine for disinfection but hygiene standards were compromised due to inadequate cleaning in all three hatcheries. The poor hatch experienced in this study suggests that there is considerable room for improvement in hatchery operations particularly with regards to hygiene and sanitation. Adequate training of hatchery operators in understanding the crucial role hygiene plays in ensuring high chick quality is needed.

Exposure to high background radiation level in the tin mining area of Jos Plateau, Nigeria  

International Nuclear Information System (INIS)

The present work deals with the radioactivity of samples of tin tailings collected from a mining site in Jos, Nigeria. The activity concentrations of the samples were measured using a gamma-ray spectrometer with a hyper-pure germanium detector. In situ dose rates at the site were also measured using a precalibrated survey meter. Potassium-40 was not detected in any of the studied samples. The activity concentrations of 238U and 232Th ranged from 17.1 x 102 to 16.6 x 103 Bq kg-1 and from 52.9 x 102 to 47.5 x 103 Bq kg-1, with mean values of 72.2 x 102 and 16.8 x 103 Bq kg-1, respectively. The absorbed dose rates were between 4.0 and 36.3 ?Gy h-1, with a mean value of 13.5 ?Gy h-1, which is much higher than the world average of 0.06 ?Gy h-1 for soil. The calculated effective dose rates varied between 2.8 and 25.4 ?Sv h-1, with a mean value of 9.4 ?Sv h-1, whereas the effective dose rates obtained for the in situ measurement varied between 6.0 and 28.0 ?Sv h-1. The annual gonadal dose equivalent was calculated as 92.4 mSv. This is much higher than the world average dose equivalent rate to individuals from soil (0.30 mSv y-1)

Geochemical trends in the Jos-Bukuru granites of central Nigeria: magmatic and metallogenic implications  

Science.gov (United States)

The Jos-Bukuru Complex is the largest individual ring complex in the Nigerian province occupying an area of approximately 430 km 2. The Complex is composed of fayalite granite and porphyrites, hastingsite granites and biotite granites. The biotite granites play host to both disseminated and vein controlled mineralization. Columbite - Cassiterite deposits occur in the Rayfield (Centre and Southern eastern parts of the Complex) and Cassiterite-wolframite bearing quartz-topaz-greisens are found as veins in the Southwestern and Northwestern (Sabon Gida and Ngell phases) parts of the Complex. Geochemical evidence suggest that the fayalite granites and hastingsite biotite granites are metaluminous, while the biotite granites are generally peraluminous. Their sum characteristics point to an A-type classification with high SiO 2, K 2O and Na 2O, low CaO and MgO. Although the major element characteristics are comparatively similar, the trace elements show strong variations. Generally the high concentrations of Rb, Li, F, Nb, Sn, Th, Y and low contents of Ba and Sr compared with low-Ca granites indicate a high degree of fractionation of magma prior to emplacement. However the element enrichment and depletion trends in the biotite granites supports a model of liquid - state diffusion and or convective fractionation analogous to those observed for chemically zoned high silica magma chamber. It is suggested that such processes have been instrumental to the formationof tin and associated mineral deposits in the complex. Thus extreme enrichment of the large ion lithophile elements and depletion of Ba and Sr are useful indicators of mineralizing processes and ore bearing plutons.

Groundwater Potential on the Jos – Bukuru Plateau, North Central Nigeria. Using Lineaments from Gravity Measurements  

Directory of Open Access Journals (Sweden)

Full Text Available The rocks of the Jos – Bukuru area in North Central Nigeria is characterized by negative and positive gravity residual anomalies ranging from –25 to +20 mGals. Lineaments were extracted from the gravity residual anomaly map for the purpose of assessing the groundwater resources in the area. The region is marked by more than one set of lineaments, each with its distinctive orientation and probably spacing. Lineaments shorter than 20 km in length are shallow structures suitable for this exercise because of their importance in groundwater recharge, transmission and discharge. In a bin size of 15oone major and one minimum striking directions between 000o and 030o were obtained. The major type lies between 000o and 015o, while the minimum one is oriented within the 015o and 030o direction. These directions correspond to the stress axis of the essentially north – south trending geological structures of Nigeria. Invasions of mineralizing fluids might had sealed some of the joints and other fractures, however where the open spaces are not sealed, weathering and erosion widen and deepened the joints paving routes for surface water flows and direct seepage into the underlying strata. On the lineament density and lineament intersection maps the closures suggest probable discontinuity of the aquifer units. On this basis of the lineament density and the lineament intersection results, the area was divided into three hydrogeological zones. Site 1 is considered most favourable for water well development, while site 3 may result in low yields or even in abortive water wells.

A Survey of Early Chick Mortality on Small-Scale Poultry Farms in Jos, Central Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available A questionnaire-based survey was conducted to investigate early chick mortality and its causes during the first two weeks on small-scale poultry farms in Jos, central Nigeria. The survey covered layer and broiler farms procuring day-old chicks from three selected hatcheries. Flock sizes varied from 20 birds up to 2000. Average mortality was 10.4 per flock with a standard deviation of 14.4. As a percentage of flock size, mortality was 11.4% with a standard deviation of 18.8%. The major causes of mortality were stress, Pullorum disease and diarrhoea. There was no significant relationship (p = 0.01, R2 = 0.02 between flock size and mortality. There was also no significant relationship (p = 0.01, R2 = 0.04 between mortality and the breed of stock. Of farms experiencing mortalities, only 28.8% consulted a veterinarian for diagnosis and treatment. The other 71% self-diagnosed the problems and instituted treatment which included vitamin supplementation or antimicrobial therapy, with enrofloxacin and gentamycin being the most popular drugs. Medication without consultation with qualified veterinarians may result in the abuse and misuse of antibiotics with the attendant consequences of resistance and the occurrence of drug residues in poultry and poultry products. The wide-spread use of antibiotics in the study area is cause for concern from both a veterinary and public health point of view. Although factors responsible for early chick mortality are complex, information on chick mortality on small-scale farms can be used for the training of farmers on its control. A better understanding of the causes of mortality in the crucial first few weeks of the chick’s life may lead farmers to rely more on better management such as better hygiene and sanitation and less on antibiotics for problems encountered during the early brooding period.

Antibacterial Activity of Ethanolic Extract of Acalypha wilkesiana Leaves Growing in Jos, Plateau State, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Antibacterial activity of ethanolic extract of Acalypha wilkesiana leaves growing in Vom, Jos, Plateau state, Nigeria was carried out to verify claims by the locals of its medicinal properties. We tested the extract for activity against Staphylococcus aureus (G+, Yersinia enterocolitica, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa and Klebsiella aerogenes (G-. The extract exhibited activity against the organisms in varying degrees. In the agar diffusion test, Y. enterocolitica showed the highest zone of inhibition (18 mm at the highest concentration of extract tested (20 mg/mL while E. coli, S. aureus, S. typhi, P. aeruginosa and K. aerogenes showed zones of inhibition of 17, 16, 15, 14 and 16 mm respectively. At extract concentration of 2.5 mg/mL, Y. enterocolitica and P. aeruginosa did not show any zones of inhibition while E.coli, S. aureus, S. typhi, and K. aerogenes showed zones of inhibition of 7, 6, 6 and 7 mm respectively. Below extract concentration of 2.5 mg/mL, there was no zone of inhibition observed with any organism. The MIC of the extract against the organisms was 5 mg/mL except on S. aureus where the MIC was 2.5 mg/mL. The MBC of the extract was 10 mg/mL against Y. enterocolitica, S. typhi, P. aeruginosa and K. aerogenes, 5 mg/mL against E. coli and S. aureus. Preliminary phytochemical testing revealed the presence of tannins, steroids, flavonoids and cardiac glycosides while saponins, alkaloids and anthraquinones were not present. The result gives scientific backing to the use of the leaves by the local people in the treatment of conditions usually associated with the organisms tested.

An Assessment of Mining Activities Impact on Vegetation in Bukuru Jos Plateau State Nigeria Using Normalized Differential Vegetation Index (NDVI  

Directory of Open Access Journals (Sweden)

Full Text Available The study area has a pathetic and deplorable condition of landuse/ landcover. The vegetal cover in the area has to be removed from the activities of tin mining which consequently resulted into adverse environmental effect such as erosion. Different forms of human induced stress such as tin mining and heavy rainfall have severely degraded soils on the Jos Plateau. Such degradation problems are also caused by deforestation, inappropriate farming system, bush burning and over-grazing which are hostile to the environment. The impact of tin mining has greatly affected the natural ecology of the study area Bukuru. Micro and macro organisms and plants have been stripped off their natural habitat due to tin mining activities. This paper therefore, assesses the mining activities impact on the vegetation in Bukuru area of Jos plateau in Nigeria. Normalized Differential Vegetation Index (NDVI techniques was adopted to Maps effect of tin mining on the vegetation for the period between 1975 and 2007 using LandSat satellite data. The result of the differential vegetation index analysis reveals a decline in vegetated surfaces in 1986 ranging from 0.04 to 0.58 indicating 0.05 and continuous loss in vegetation over the study area in 2007 (vegetated surface decrease by 0.08 between 1986 and 2007. The decrease in vegetated surface is due to intensive mining and cultivation.

Gamma ray spectroscopy of soil samples from apple orchards in Lamingo dam and Vom area in Jos, Plateau State, Nigeria  

International Nuclear Information System (INIS)

Five samples each were collected from the apple orchards in Lamingo dam and Vom area of Jos East and Jos South local government areas respectively. The samples were allowed to decay for three weeks to ensure efficiency in acquiring the radionuclides. The samples were analyzed using Gamma Ray spectroscopy. Barium- 204 with gamma activity energy level 1765.50keV was used to check the presence of Uranium-235 in the samples. The results showed that samples Lams 2,3,4 and Voms 1,4,5 had high gamma activity energy levels of 2436.356keV, l837.24keV 2928.37 keV and 1656.32keV, 1635.48keV, 2351.87keV respectively as compared to (204B). While Lams 1,5 and Voms 2,3 had relatively lower gamma activity energy levels of 1325.23KeV, 1272.73keV and 1462.61KeV, 1183.24keV respectively. The samples with high gamma activity energy levels imply that radionuclide in the form of 235U is present in trace amounts in the sampled areas. This can affect the output of apples cultivated in such areas as the chemical composition or structure of plants will be altered.

Gamma activity and radiation dose in concrete building blocks used for construction of dwellings in Jos, Nigeria.  

Science.gov (United States)

Radioactivity concentrations of concrete building block samples made and used in Jos, Nigeria, were determined using a gamma ray spectrometry method. The mean values of the radioactivity concentrations were calculated as 66, 126 and 589 Bq kg(-1) for (226)Ra, (232)Th and (40)K, respectively. The radium equivalent activities ranged between 131 and 712 Bq kg(-1), with six of the samples exceeding the UNSCEAR reported maximum permissible level of 370 Bq kg(-1). The mean radium equivalent activity (292 Bq kg(-1)) is higher than the values available in the literature for some countries by factors ranging between 2 and 5, a situation that can be traced to the practice of sourcing sand aggregates from mining sites. The indoor annual effective dose for a dwelling of dimension 3.6 x 3.6 x 3.0 m(3) was calculated as 0.81 mSv. PMID:16702239

Natural radionuclides concentrations for soil samples from old mine spoil dumps in Jos and environs, Plateau state Nigeria  

International Nuclear Information System (INIS)

The concentrations of natural radionuclides in soils from around the mining sites in Jos and Bukuru in Plateau State were investigated with an aim of evaluating the environmental radioactivity and radiological health hazards. Concentrations of the primordial radionuclides in the samples were determined by solar MB3 Atomic Absorption Spectrometry (AAS). In the soil types generally, the concentration of ''4''0K is higher than than that of ''2''3''8U and ''2''3''2Th. This could be attributed to natural potassium, which is an essential constituent of soil. The mean values of the concentrations of the primordial radionuclides were found to be ''4''0K (15.50±0.70) ppm, ''2''3''8U (8.55±0.45) ppm and ''2''3''2Th (2.10±0.40) ppm respectively

Antimicrobial resistant profile of Streptococcus pneumoniae isolated from the nasopharynx of secondary school students in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Background : Antimicrobial resistance in Streptococcus pneumoniae has compromised the effectiveness of therapy for pneumococcal diseases and asymptomatic nasopharyngeal carriers play an important role in transmission of resistant strains. Method : Eighty-eight volunteer students attending 2 secondary schools in Jos, Nigeria were involved in this study to determine the antimicrobial resistant profile of Streptococcus pneumoniae isolated from the nasopharynx. The study population consisted of males and females between the ages of 15 - 25 years. Nasopharyngeal swab samples were analyzed for the presence of S. pneumoniae using standard bacteriological methods. The isolates were subjected to antimicrobial susceptibility testing using the disc diffusion method. Results : S. pneumoniae was isolated from 37(42.04% of the 88 samples. Isolates showed the highest resistance of 12 (32.43% to erythromycin and lowest resistance of 4(10.81% to ciprofloxacin. The resistance profiles for the 26(70.27% penicillin-sensitive and 11(29.72% penicillin-resistant isolates were similar. Both exhibited varying degrees of resistance to several groups of antimicrobials. However, isolates found to be resistant to penicillin showed a higher degree of resistance to other antimicrobial agents. Conclusion : This study has shown that some secondary school students are carriers of multiple antibiotic-resistant S. pneumoniae .

Measurement of radionuclides concentration of some commonly consumed vegetables and the soil samples in Jos and Bukuru metropolis, Plateau state  

International Nuclear Information System (INIS)

Studies of radiation level and radionuclide distribution in soil and vegetables of Bukuru and Jos metropolis in Plateau State, Nigeria, were undertaken to provide baseline data for the assessment of the impact of radionuclides which occur as a result of the tin mining activity that was set up in the region and to understand the behaviour of the radionuclides in the soil as well as the uptake of these radionuclides by the vegetables which are commonly consumed in the area. As part of this project the concentration of three important natural radionuclides namely: ''4''0K, ''2''3''2Th and ''2''3''8U have been measured in a number of geological samples and biological samples using the Atomic Absorption Spectrometry (AAS). The measurement showed that ''4''0K activity concentration is mostly high in the leafy vegetables with an average value of (17.04±0.04) ppm possibly as a result of its double intake both from the root uptake and from the atmosphere. While the ''2''3''8U and ''2''3''2Th are minimal in the leafy vegetables with an average value of (2.06±0.01) ppm and (0.29±0.02) as well as in the root vegetables. Though these could be higher relative to their expected values in normal soil due to fertilizer applications and washed tailings into the streams where the vegetables are mostly farmed

Seismic data acquisition over San Juan volcanic field, San Juan sag, south-central Colorado  

Energy Technology Data Exchange (ETDEWEB)

The San Juan sag, a foreland basin along the Uncompahgre-Brazos uplift, contains Mesozoic sediments overlain by up to 10,000 ft of Tertiary volcanics. Petroleum exploration beneath thick volcanic cover requires successful acquisition of seismic data; however, experience elsewhere has generally produced only marginal results. Commencing in 1983, Meridian Oil recorded 18 seismic lines comprising 260 mi of conventional and portable data. Noise test were performed at two sites to evaluate seismic response and to determine source and receiver parameters. Vibroseis, shothole, and surface dynamite were examined as sources and gave comparable results. Coherent noise trains with velocities from 4,000 to 8,000 ft/sec and dominant frequencies of 10 to 15 Hz were generated in the Tertiary section. The predominant factor affecting data quality was outcrop lithology. Data recorded over alluvial and other Quaternary deposits tended to be good to fair. Data quality over Tertiary volcanics was variable and highly unit dependent, ranging from fair over andesites and volcaniclastics, poor over ash-flow tuffs, and uniformly very poor over basalts. Seismic source appeared to have only a minor effect on quality. Data processing involved no unusual operations. Velocity filtering was used to suppress near-surface generated coherent noise, Refraction statics were applied to lines with significant elevation or lithologic variations. A successful acquisition program helped to establish the presence of a Mesozoic sedimentary section beneath the volcanics. these data revealed large structural features within the sedimentary section as well as a dramatic angular unconformity at the top of the Cretaceous section.

Occurrence of Hepatitis C Virus infection in type 2 diabetic patients attending Plateau state specialist hospital Jos Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Glucose intolerance is observed more in patients with HCV infection compared with control subjects with liver disease, Initial studies suggested that Hepatitis C virus infection may be an additional risk factor for the development of diabetes mellitus. This study was therefore carried out to determine the correlation of HCV infection and diabetes. Methods Three hundred (300 confirmed type 2 diabetic patients were screened for hepatitis C virus antibodies at the Plateau state specialist hospital, Jos, using Grand diagnostic test strip. Questionnaire comprising of age, sex, family history on diabetes, duration of disease and marital status were issued to subjects. Results Overall result showed that the prevalence rate of HCV infection was 33(11%. In response to diabetic status, females subjects had a higher prevalence of 178(59.3% compared to males 122(40.7%. Those aged 47–57 recorded the highest seroprevalence 10(30.3% to the Hepatitis C Virus, while Patients without family history of diabetes showed a higher seroprevalence of 13(39.4%. Subjects who never had any blood transfusion recorded a prevalence rate of 6(18.2%. Marital status showed no significant difference [(P = 0.275; P.0.05]. Considering duration of developing diabetes, patients within the range of 1–10 years diabetic status recorded the highest prevalence rate 25(75.8% compared to other ranges considered. Conclusion This study hence, suggests a relatively strong association between HCV infection and diabetes, this therefore call for an urgent approach strategy in the control and management of this disease of the endocrine system.

Tectonics and evolution of the Juan Fernandez microplate at the Pacific-Nazca-Antarctic triple junction  

Science.gov (United States)

Magnetic and bathymetric profiles derived from the R/V Endeavor survey and focal mechanism studies for earthquakes on two of the Juan Fernandez microplate boundaries are analyzed. It is observed that the Nazca-Juan Fernandez pole is in the northern end of the microplate since the magnetic lineation along the East Ridge of the microplate fans to the south. The calculation of the relative motion of the Juan Fernandez-Pacific-Nazca-Antarctic four-plate system using the algorithm of Minster et al. (1974) is described. The development of tectonic and evolutionary models of the region is examined. The tectonic model reveals that the northern boundary of the Juan Fernandez microplate is a zone of compression and that the West Ridge and southwestern boundary are spreading obliquely; the evolutionary model relates the formation of the Juan Fernandez microplate to differential spreading rates at the triple junction.

Labelling of precipitation by stable isotopes ( 18O, 2H) over the Jos Plateau and the surrounding plains (north-central Nigeria)  

Science.gov (United States)

Stable isotopes oxygen-18 and deuterium were studied in precipitation at five meteorological stations on the Jos Plateau and the surrounding plains. Rainwater is progressively depleted in heavy isotopes from the beginning of the rainy season towards the peak of the season, with the most depleted values being recorded in the August rains. Isotopic variation with altitude is very evident between the stations on the plateau and that on the plain. The isotope-altitude gradient is probably concealed by the mass-effect of the Jos Plateau. A Local Meteoric Line (LML) of the type ?D=7.8 ?18O+10.6 was obtained with all the available isotopic data. When only the data for the rain for the months of June through August are used, a relation ?D=8.4 ?18O+14, close to the Global Meteoric Water line but with a higher deuterium excess (d) is obtained. This suggests a contribution of continental vapour mass to precipitation over the region. On the basis of the stable isotope relationships, three categories of recharging rainwater are defined, which may have implications in groundwater tracing: i) precipitation of the early and perhaps late rainy season, enriched in heavy isotopes ii) precipitation of the advanced stage of the rainy season, marked by non-evaporated rains (slope 8, d > 10) iii) precipitation of the peak of the rainy season (August, September), depleted in heavy isotopes.

SCAP optimization of the Pasajes de San Juan power station  

Energy Technology Data Exchange (ETDEWEB)

In July 1990 the company Iberduero, now Iberdrola, decided to carry out a development project using the Spanish technology SCAP in the Pasajes de San Juan power plant. This methodology, featured by the utilization of adaptive predictive control methodology, had been successfully applied in order to achieve the optimization of other industrial processes. The ultimate aim of this project was the replacement of the power station conventional control system, with a SCAP control system with a distributed structure able to optimize the electric energy generation process by optimizing power station operation, maximizing efficiency and working life, reducing maintenance costs, and increasing safety and availability. The project was divided into two stages to evaluate the quality of SCAP technology in the control and optimization of a power station. In the present report, the results obtained in the control of the most critical variables during the power station operation are gathered together. Beforehand, and in order to place these results in a suitable context, the project proceedings summarized in the following phases are considered: the SCAP technology; problems in a thermal power plant; and the Pasajes de San Juan power plant and its control system. The results are presented through comparative graphs that show the performance of the SCAP system as compared to the power station conventional control. 17 figs., 4 tabs., 11 refs.

Modeling of Tidal Circulation in Strait of Juan de Fuca  

Science.gov (United States)

A high-resolution three-dimensional hydrodynamic model (EFDC) was developed to simulate the barotropic tidal circulation and residual currents in the eastern region of Strait of Juan de Fuca. Complex circulation patterns have been observed in this high tidal energy regime due to complicated bathymetry and coastal boundaries. In the present study, the model was driven by major semi-diurnal and diurnal tidal constituents, as well as surface wind. The model consists of multiple eastern open boundaries, which connect to a number of estuarine systems. Historical water surface elevation and ADCP data were used to calibrate the model over a period covering the spring and neap tidal cycles. A localized high-resolution grid was developed near Port Angeles Harbor to study the dynamics of a large tidal eddy. The effects of the bathymetry and coastal boundaries on the tidal circulation and residual currents were investigated. The long-term transport field was calculated using a Lagrangian approach. Comparisons between model results and field data indicate that the model reproduces the tidal dynamics in the Strait of Juan de Fuca well. Model results show that strong tidal residual currents are generated due to tidal nonlinearity and complex geometry.

Energy. Inspiration for the future. Essays in honour of Jos Bruggink's retirement from ECN  

Energy Technology Data Exchange (ETDEWEB)

This 'liber amoricum' is published at the occasion of the retirement of Jos Bruggink, who worked for the unit Policy Studies of the Energy research Centre of the Netherlands (ECN) from 1979 to July 2011. The central theme in this volume is: Is it useful at all to study the energy future? This book collects views on the future of a number of energy-related issues. Marc Londo and Wim Sinke give their views on biomass and solar energy. Piet Boonekamp reflects on studying the energy future for the Netherlands and concludes that despite all our efforts there has been limited progress towards a secure, affordable and clean energy supply. However, in any energy future, energy savings is a 'no-brainer'. Pieter Boot analyses the ambition and progress on a sustainable energy system in four Northwestern European countries, and how coordination between them could help transition. Dolf Gielen discusses the role of innovation in all of this, and Bob van der Zwaan and Hilke Rosler talk about whether we can foretell anything at all about that process. Are the billions of people without access to modern energy finally going to get connected and what policy does that take? Jan Cloin and Tineke Roholl reflect on this question, while Raouf Saidi and Rahul Barua wonder about the promise of improved cook stoves. Lastly, Heleen de Coninck asks what international developments mean for climate change, and what institutions matter? The titles of the essays are (1) Changing views in Dutch policy making and support by ECN; (2) Changes in Northwest European energy systems: different views, no coordination yet; (3) Energy technology and innovation policy: the value added of models; (4) Long-term energy scenarios: Why?; (5) The silent revolution: solar energy on its way to large-scale use; (6) The trouble with biofuels; (7) Markets for Clean Cookstoves: A Think Piece for Development Cooperation Positioning; (8) Climate mitigation and energy for all: is there a role for international collaboration?; (9) Energy and Development Policy: How to obtain universal access in 2060?.

Directory of Open Access Journals (Sweden)

Full Text Available Juan Carandell Pericay (1893-1937, geólogo y geógrafo ligado a la Institución Libre de Enseñanza, escribió unos trescientos títulos, con una actividad científica e intelectual muy polifacética: geología, geografía física, humana y regional, libros de viaje y excursiones pedagógicas, semiología gráfica, divulgación científica y otras actividades intelectuales y artísticas. Una parte significativa de dichas obras estuvo dedicada a las Béticas, en general, y a Sierra Nevada en particular. Aspectos considerados por Carandell sobre Sierra Nevada son los relativos a su geología, geomorfología y tectónica, la erosión y sus causas físicas y humanas, la geografía humana ?con especial importancia para el tema del hábitat? y otra variada gama de temas entre los que merece mención la faceta de las representaciones del paisaje, en todas las cuales demostró no sólo sus sólidos conocimientos geológicos y geográficos, sino incluso una calidad artística más que apreciable.

Analysis of causes for reject x-ray films as a quality assurance elements in diagnostic radiology in Jos university teaching hospital  

International Nuclear Information System (INIS)

The film reject rate and quality assessments studies were carried out at the Jos University Teaching Hospital. The rejected films collected and counted with respect to type, size and reasons for rejection were carried out for two calendar years. The observed reject rates were found to be nearly independent of the type of X-ray examination, which 68% of waste film reflected the nature and skills employed. The mechanical influence of equipment (machine fault is 11%, film rejection due to poor processing (dark room fault) was found to be 8% and for film rejection due to wrong identification, fogged film, uncooperating patient (patient movement) are 5%, 5% and 3% respectively. The deterioration in the quality of films and film processing conditions, ineffective quality assurance programs and inadequate regular staff training form a possible explanation for observed waste films which could have been avoided.

International Nuclear Information System (INIS)

In this project, measurement of x-ray radiation dose level during radiological examination in Jos university teaching hospital and Plateau State specialist hospital at different locations within the department were carried out using radiation survey meter. The results were converted from micro sievert per hour (?Sv/hr) to milisievert per year (mSv/yr). The radiation levels from the two hospitals visited ranged from 1.3m Sv/yr to 8.4m Sv/yr. This implies that all the radiology departments visited are still operating within the safety limit having less than 20 mSv/yr which is the standard permissible radiation level recommended per year

A new record for American Bullfrog (Lithobates catesbeianus) in San Juan, Argentina / Nuevo registro de rana toro americana (Lithobates catesbeianus) en San Juan, Argentina  

Scientific Electronic Library Online (English)

Full Text Available SciELO Mexico | Language: English Abstract in spanish Se presenta un nuevo registro de Lithobates catesbeianus (rana toro americana) en Argentina. L. catesbeianus fue introducida por primera vez a la provincia de San Juan hace 11 años en el Departamento Calingasta, donde el hábitat es pre-cordillerano. El nuevo registro es para el Departamento Zonda en [...] la provincia de San Juan, en el desierto del Monte. En este sitio, L. catesbeianus usa estanques artificiales para la reproducción y desarrollo del renacuajo. Los estanques reciben agua de un sistema de riego que conecta todas las tierras de la agricultura en la región. Los renacuajos utilizan los canales de riego para moverse entre los estanques. Sugerimos que se establezcan leyes para prevenir invasiones futuras y para lograr un manejo integrado de las poblaciones silvestres de rana toro que se encuentran en San Juan. La prevención de futuras invasiones y el manejo de las poblaciones establecidas de esta especie requieren la cooperación de numerosas entidades tanto gubernamentales como privadas. Abstract in english We report a new record of Lithobates catesbeianus (American bullfrog) from Argentina. L. catesbeianus was first introduced to San Juan Province 11 years ago in Calingasta Department, where the habitat is pre-cordilleran. The new record is for Zonda Department, San Juan Province, in the Monte desert [...] region. Here, L. catesbeianus uses artificial ponds for reproduction and tadpole development. These ponds receive water from an irrigation system that connects the whole agriculture land in the region. The tadpoles use the irrigation canals to move among ponds. We suggest that legislation should be established to prevent future invasions and to achieve sustainable management of the wild American bullfrog populations in San Juan. Prevention of future invasion and management of established populations of this species requires the cooperation of numerous stake holders.

Full Text Available El artículo contiene la primera parte de un estudio sobre la interpretación de Orígenes al capítulo 6 del Evangelio de Juan. Este estudio se propone primero reunir y examinar los distintos textos, relacionados a la exégesis de Jn 6, contenidos en las obras de Orígenes que nos han llegado. En un segundo momento se buscará trazar las líneas de fondo de la interpretación origeniana a Jn 6. Siendo el material abundante, en esta primera parte se presentan y examinan los textos relacionados a la parte narrativa (Jn 6,1-21, y se inician a presentar los textos relacionados al discurso de Jesús (Jn 6,35-59. En efecto, está claro que el interés de Orígenes se ha dirigido particularmente al discurso en el que Jesús se declara "pan de la vida". Aquí se verán los textos contenidos en el De Oratione, en el Comentario a Juan, y en el Comentario a Mateo. En la segunda parte del estudio se terminará de presentar los textos relacionados al tema del "pan de la vida" y que están contenidos en las Homilías al Génesis, Homilías al Éxodo, Homilías al Levítico, Homilías a los Números y Homilías a Josué. Haré también una revisión y balance de la presencia de esta temática en el resto de las obras origenianas que nos han llegado. En fin, intentaré poner de relieve las líneas de fondo de la exégesis de Orígenes a Juan 6The article presents the first part of a study on Origens' interpretation of chapter 6 of the gospel by Saint John. The study attempts to gather and examine the various texts related to the exegesis about Jn 6, comprised in the works by Origen which we have come to us. Then, there is an attempt to outline the foundations of Origen's interpretation to Jn 6. Given that the material is abundant, this first part presents and examines only the texts related to the narrative part (Jn 6, 1-21 and starts introducing the texts related to Jesus' words (Jn 6, 35-59. In fact, it clear that Origen's interest focuses particularly on Jesus' speech in which He calls himself "bread of life". This paper presents the texts comprised in De Oratione, Comment on John, and Comment on Mathew. The second part of this study presents the remaining texts related to the "bread of life" speech, which are contained in the Homilies on the Genesis, Homilies on Exodus; Homilies on Leviticus, Homilies on Numbers and Homilies on Joshua. The author also makes a balance of the presence of this issue in the other works by Origen which have to come to our days, to end up emphasising the train of thought of Origen's exegesis about Jn 6

Juan Carlos Rodríguez y la renovación de marxismo althusseriano  

Directory of Open Access Journals (Sweden)

Full Text Available In the immediate aftermath of 1968, a number of works on Marxist literary theory appeared that were destined to command the attention not only of writers who were re- cognizably ‘Marxist’ or ‘Marxian’ but of others who boasted little in the way of allegiance to the Marxist tradition, however broadly defined. Two such works were Terry Eagleton’s Criticism and Ideology (1976 and Fredric Jameson’s The Political Unconscious (1981. While deeply and confessedly indebted to Louis Althusser for kick-starting their careers, inspirationally speaking, both Eagleton and Jameson were subsequently to reveal an ambiguous, even troubled relation to the French Marxist: Eagleton, through a series of texts that, their unquestionable distinction notwithstanding, run hot and cold in their commitment to ‘Althusserianism’; Jameson, through a brand of Hegelianizing Marxism that finally proved unable to take on board the full complexity of the Althusserian legacy. Preceding both these scholars chronologically, and bearing comparison with them in terms of intellectual range, ambition, and productivity, was Juan Carlos Rodríguez, whose Teoría e historia de la producción ideológica appeared in 1974. Except that there the similarities end, for whereas Eagleton and Jameson were destined to achieve star status within their profession, a rather different career trajectory awaited Rodríguez.

Groundwater is mainly recharged by the San Juan river, which originates in the high Cordillera of the Andes, and is consequently depleted in isotopic content. However, this study led to the conclusion that precipitation over the surrounding hills (altitudes between 1500 and 3000 m), which is isotopically more enriched than the San Juan river source, must be taken into account in evaluating the groundwater inventory in different areas of the valley. About 80 wells covering the whole area, especially the piedmont of the hills, were sampled and analysed to study the regional influence of the different inputs. The interpretation of the results obtained suggests that the San Juan river has recharged most of the groundwater stored in the valley. Tritium levels provide evidence for the present area of recharge, not only limited to the alluvial fan, but also through the river bed in places where particular structural patterns and permeable deposits permit infiltration. The influence of water from Sierra Chica de Zonda, on the eastern border of the valley, is not significant, at least under present conditions. An important contribution of water from Sierra de Pie de Palo is evidenced in the southeast, i.e. groundwater in this area shows isotopic values that are interpreted as a mixture of water from the San Juan river with samples from the Sierra de Pie de Palo springs.

Occurrence, quality, and use of ground water in Orcas, San Juan, Lopez, and Shaw Islands, San Juan County, Washington  

Science.gov (United States)

Ground water, which supplies most of San Juan County 's water needs, occurs in both bedrock and glacial drift. Water in the bedrock occurs in fractures in the otherwise dense, poorly permeable rock. Deposits of sand and gravel in the glacial drift provide the best yields to wells drilled into unconsolidated materials. Specific capacities of bedrock wells are typically low, and those of glacial-drift wells considerably higher. Ground water is high in dissolved solids and hardness; 29 of 56 wells sampled had water classified as very hard. Sixteen percent of the 171 ground-water sites tested for indicator bacteria had positive counts of one or more of these bacteria: total coliform , fecal coliform, fecal streptococcus. Nine percent of the 279 wells sampled for chloride in September 1981, appear to be affected by seawater intrusion. All of these wells are located within a mile of the coast; 60 percent of these wells are on Lopez Island. In 1980 an estimated total of 220 million gallons of ground water was withdrawn for all uses. Ninety percent of all ground-water use is for domestic and public supply purposes. Heavy pumpage on northern and southern Lopez Island correlates with areas having high chloride concentrations.

A jewel in the desert: BHP Billiton's San Juan underground mine  

Energy Technology Data Exchange (ETDEWEB)

The Navajo Nation is America's largest native American tribe by population and acreage, and is blessed with large tracks of good coal deposits. BHP Billiton's New Mexico Coal Co. is the largest in the Navajo regeneration area. The holdings comprise the San Juan underground mine, the La Plata surface mine, now in reclamation, and the expanding Navajo surface mine. The article recounts the recent history of the mines. It stresses the emphasis on sensitivity to and helping to sustain tribal culture, and also on safety. San Juan's longwall system is unique to the nation. It started up as an automated system from the outset. Problems caused by hydrogen sulfide are being tackled. San Juan has a bleederless ventilation system to minimise the risk of spontaneous combustion of methane and the atmospheric conditions in the mine are heavily monitored, especially within the gob areas. 3 photos.

Full Text Available Notre travail prend en discussion l’un des plus célèbres libertins de l’histoire littéraire, Don Juan, tel qu’il est repris dans la pièce de Molière. Plus précisément, nous nous proposons d’étudier le discours de séduction de Don Juan dans les différentes hypostases dans lesquelles il apparaît. Nous voulons mettre en parallèle le discours de Don Juan devant Done Elvire, et celui devant la paysanne Charlotte, pour mettre en évidence deux aspects: la composante affective, c’est-à-dire l’insertion du moi dans le discours, et la composante séductrice, notamment le rapport entre le moi-séducteur et l’objet de la séduction.

Une des fêtes les plus importantes de la communauté de La Jalca, Province de Chachapoyas, Amazonas, est celle de la Saint-Pierre où l?on exécute une danse de l?ours très semblable à celle des ukukus du sud péruvien. Le narrateur du récit que nous publions ici assimile ce rite à l?histoire de Juan Oso (Jean de l?Ours très connue dans le monde andin. L?importance de l?ours dans cette culture des hautes terres amazoniennes est fondamentale. En quechua local, l?ours s?appelle ?puma? et partage avec le puma de la forêt les caractéristiques de puissance effrayante et de pouvoirs surnaturels. Le fils de l?ours, Juan, évoque les relations ambiguës liant les ?chrétiens? des hautes terres d?Amazonas et les ?sauvages? de la forêt. Una de las fiestas más importantes de la comunidad de La Jalca, Provincia de Chachapoyas, Amazonas, es la de San Pedro en la que se representa un baile del oso muy semejante al baile de los ukukus del sur peruano. El narrador del cuento que publicamos aquí asimila este rito a la historia de Juan Oso, muy conocido en el mundo andino. La importancia del oso en esta cultura de la ceja de selva alta es fundamental. En quechua local, el oso se llama ?puma? y comparte con el puma de la selva las características de fuerza temible y poderes sobrenaturales. El hijo del oso, Juan, evoca las relaciones ambiguas existentes entre los ?cristianos? de la serranía de Amazonas y los ?chunchos? de la selva. JUAN PUMA, THE BEAR'S SON. A QUECHUA TALE FROM LA JALCA, CHACHAPOYAS. One of the most important feasts of the community of La Jalca, Province of Amazonas, is that of Saint Peter in which a bear dance similar to the southern Peruvian dance of the ukukus is performed. In the story published here, the narrator assimilates this rite with the tale of Juan Oso, another story which is well known throughout the Andes. The importance of bears in Amazonas highland culture is fundamental. In local Quechua, bears are known as pumas and they share the fearful strength and superhuman powers which characterize jungle ?pumas?. The bear?s son, Juan, calls to mind the ambiguous relations linking the ?Christians? of the highlands of Amazonas and the ?savages? of the jungles.

Isotopic study of the aquifer in the Tulum and Ullum-Zonda Valleys, San Juan, Argentina  

International Nuclear Information System (INIS)

An isotopic and hydrochemical study on groundwater from Ullum-Zonda and Tulum Valleys, San Juan province, Argentina, has been performed. Recharge areas and the different water types feeding the basin groundwater were determined. Gross isotopic differences among the San Juan river, originated in the high Cordillera de los Andes (?18O = -16 per mille), rainwater over the surrounding hills (?18O = -7 per mille) and the more positive local precipitation favoured this characterization. Also 14C content of twelve groundwater samples are presented. The interpretation of these results is discussed. (author). 9 refs, 3 figs, 2 tabs

Estimation of annual effective dose due to natural radioactive elements in ingestion of foodstuffs in tin mining area of Jos-Plateau, Nigeria  

Energy Technology Data Exchange (ETDEWEB)

Soils and food crops from a former tin mining location in a high background radiation area on the Jos-Plateau, Nigeria were collected and analyzed by gamma spectrometry to measure their contents of {sup 40}K, {sup 238}U and {sup 232}Th. As well as collecting samples, in situ dose rates on farms were measured using a precalibrated survey meter. Activity concentrations determined in food crops were compared with the local food derivatives or diets to investigate the possible removal or addition of radionuclides during food preparation by cooking or other means. Potassium-40 was found to contribute the highest activity in all the food products. The activity concentration of {sup 40}K, {sup 238}U and {sup 232}Th in local prepared diets ranged between 60 and 494 Bq kg{sup -1}, between BDL and 48 Bq kg{sup -1} and between BDL and 17 Bq kg{sup -1}, respectively. The internal effective dose to individuals from the consumption of the food types was estimated on the basis of the measured radionuclide contents in the food crops. It ranged between 0.2 {mu}Sv y{sup -1} (beans) and 2164 {mu}Sv y{sup -1} (yam) while the annual external gamma effective dose in the farms due to soil radioactivity ranged between 228 {mu}Sv and 4065 {mu}Sv.

Poesía y poliorcética : El arte de conquistar el imaginario en el Auto de San Lorenzo de José de Anchieta  

DEFF Research Database (Denmark)

The conquest and colonization of a territory entails a series of operations designed to eliminate a whole model of culture. After wartime, the colonization and subsequent disposal of the collective imagination of the conquered space is imposed by the invadors. The operations performed in order to carry out such a removal occur mainly in the space of discourse. Indeed poetry â??or literature in generalâ?? is one of the discourses used to execute this operation. This article aims to establish a connection between the art of war and the colonization of the imagination through poetry. I will try to point out that the two mechanisms of invasion cannot be separated if the aim is to control the other effectively. Following this perspective I will analyze El auto de San Lorenzo written in Brazil in the middle of the XVI century by the Jesuit José de Anchieta. This play is precisely one of the most representative evidences of what I will call here a total conquest.

The geology and petrology of Volcán San Juan (Nayarit, México) and the compositionally zoned Tepic Pumice  

Science.gov (United States)

Volcán San Juan is the westernmost Quaternary composite volcano in the Mexican Volcanic Belt. Its activity is divided into three stages of decreasing eruptive volume. During stage-1 activity, the main cone of San Juan and the adjacent Cerro Alto grew to a combined volume of ˜60 km 3 through eruption of hornblende-bearing andesites, dacites, and rhyodacites. Stage 1 included explosive eruptions of hornblende-dacite and an andesite dated at 33,750 a (years ago) and 23,010 a. Stage-2 activity involved a major Plinian eruption 14,770 a that produced the hypersthene-hornblende-bearing, compositionally zoned, rhyodacitic-andesitic Tepic Pumice and led to formation of an oval-shaped caldera 4×1 km in diameter. Tepic, the capital city of Nayarit State, with a population of ˜250,000, lies at the NE foot of Volcán San Juan. This location was buried under 2-9 m of rhyodacitic pumice-fall deposits from the Tepic Pumice eruption. Erosion has since removed virtually all exposures of Tepic Pumice >15 km from the caldera. The estimated volume of erupted tephra is 5.6 km 3, equivalent to 1.2 km 3 of magma. Modeling of the eruption dynamics indicates that as the eruption evolved the column height increased from ˜15 km to ˜24 km and maximum mass discharge rate increased from ˜3×10 6 kg/s to ˜6×10 7 kg/s. During stage-3 activity, a hornblende-andesitic lava dome partially filled the caldera and sent block lava flows down the north slope of the cone; total erupted volume was ˜0.55 km 3. Compared to other composite volcanoes of the western Mexican Volcanic Belt, the products from San Juan have the highest Sr contents and the lowest Rb, Y, Yb, and Lu contents, resulting in high La/Yb and Sr/Y, with low Rb/Sr. These observations indicate a strong slab-melt component at San Juan, consistent with its proximity to the Middle America Trench where young, hot lithosphere is subducting. The San Juan andesites, dacites, and rhyodacites also have relatively high 87Sr/ 86Sr, 206Pb/ 204Pb, 207Pb/ 204Pb, and 208Pb/ 204Pb, and low ?Nd values compared to these other volcanoes, which appear to reflect significant crustal contamination of San Juan's magmas.

Assessment of external and internal doses due to farming in high background radiation areas in old tin mining localities in Jos-plateau, Nigeria  

Energy Technology Data Exchange (ETDEWEB)

Farming on soils situated in high background radiation areas can result to enhanced radiation exposure scenarios and pathways to humans. To assess the likely levels of exposures, farm soil samples were collected from different farmlands in three old tin mining localities (Bitsichi, Bukuru and Ropp) in Jos Plateau Nigeria, known for high radiations. The soil samples were analyzed for the activity concentrations of {sup 226}Ra, {sup 232}Th and {sup 40}K, using gamma-ray spectroscopy. The outdoor annual effective dose rates were calculated using the activity concentrations of the radionuclides and were found to vary from 0.07 mSv to 2.02 mSv across the three localities. Considering dust generation from soil tillage and inadvertent ingestion of soil particles, the likely internal radiation hazards were estimated using conservative dust and soil loading factors. The total average annual effective dose rates due to {sup 226}Ra and {sup 232}Th that could result from dust inhalation and ingestion of soil particles were 16.9 {mu}Sv, 8.1 {mu}Sv and 8.8 {mu}Sv, respectively for Bitsichi, Bukuru and Ropp. Though these values are about 5% the outdoor exposures to the farmers in those farms and greater than 1 {mu}Sv y-1, from the point of view of radiation protection and risk, they are significant. It suffices to say, therefore, that the results of this study will create the possibility of the importance to evaluate the health risk among the farming population and workplace environments which often is not covered by regulations concerning health protection.

Feria Exposición Agrícola y Pecuaria de San Juan de los Remedios (1857. Cuba - (Agricultural and Cattle Fair Exhibition of San Juan de los Remedios (1857. Cuba

Full Text Available ResumenEn una moción presentada en el cabildo de San Juan de los Remedios porD. Francisco Javier Balmaseda y Jullien dirigida al Capitán General de la Isla de Cuba en febrero de 1857, se solicitaba la autorización para celebrar una Feria Exposición Agrícola y Pecuaria en fecha que coincidiera con la del santo patrono de la villa, San Juan Bautista. La primera de estas ferias se celebró en ese año siguiéndole seis eventos más, excepto en el año 1861. En el presente artículo se dan a conocer los aspectos más importantes de su reglamento, que por sus características técnicas, lo consideramos muy avanzado para la época. Los premios así como lo premiado, representan un abanico del universo pecuario anteponiéndose a la necesidad de la utilización de las materias primas locales que sustituyeran a las importadas. Las medallas otorgadas a los premiados jugaron un papel fundamental en la historia local, pues en éstas aparecía el escudo originariode la villa, las que encontradas por el historiador José A. Martínez-Fortún y Foyo fundamentaron que hoy día sea el que pueda ostentar la ciudad. Inferimos que estas celebraciones jugaron un doble papel en la vida remediana: impulsaron el desarrollo ganadero y agrícola local y permitieron que Remedios fuera más conocido en el resto del país.SummaryIn a motion presented in the town council of San Juan de los Remedios by D.

In the present article are given to know the most important aspects of its regulation that for its technical characteristics, we considerate to be very advanced for that time. The prizes as well as that rewarded, represent the cattle universe, being prefixed to the necessity of the use of the local raw matters that substitute those cared. The medals granted to the winners played a fundamental role in the local history, because in these the shield native of the village appeared, those that were found by the historian José A.

Paleoenvironmental interpretation using fossil record: San Juan Raya Formation, Zapotitlán basin, Puebla, Mexico / Interpretación paleoambiental empleando el registro fósil: Formación San Juan Raya, cuenca de Zapotitlán, Puebla, México  

Scientific Electronic Library Online (English)

Full Text Available SciELO Mexico | Language: English Abstract in spanish La Formación San Juan Raya es mundialmente reconocida debido a su alta diversidad y abundancia fosilífera. En este estudio se reconocieron e interpretaron nueve biofacies y tres icnofacies tomando como base la influencia de diversos factores como los cambios relativos en el nivel del mar, la tasa de [...] sedimentación, la salinidad del agua y la consistencia del substrato. Entre estos factores, al parecer las variaciones en la salinidad del agua fueron muy importantes en el desarrollo y remplazo de las asociaciones de organismos. La mayor parte de los organismos que conformaron las distintas biofacies e icnofacies, habitaron en ambientes de zona de rompiente y de plataforma interna. El objetivo de este trabajo es el de proveer una reconstrucción de las diferentes comunidades bentónicas y de los ambientes de depósito de un sector de la Formación San Juan Raya durante el Cretácico Temprano. Los resultados indican que el modelo paleoambiental del área de estudio corresponde a un sistema clástico marino somero dominado por tormentas. Finalmente, a lo largo de los 765.5 m de la columna estratigráfica compuesta, se identificaron nueve ciclos transgresivos-regresivos, en los cuales las etapas de somerización se encuentran en los niveles de 200 y 500 m, mientras que las condiciones de mayor profundidad están ubicadas en los 300, 400 y 765.5 m respectivamente. Abstract in english The San Juan Raya Formation is world-wide recognized because of the high diversity and abundance of fossils. In this study nine biofacies, three ichnofacies and ten lithofacies were recognized and interpreted on the basis of the influence of several environmental factors such as water depth change, [...] sedimentation rate, water salinity and substrate consistency. Among these factors, salinity variations were apparently crucial for developing and replacement of the different biofacies. Most of biofacies and ichnofacies inhabited in subtidal, shoreface and inner shelf zones. The aim of this investigation is to provide a comprehensive reconstruction of the different faunal benthonic assemblages and paleoenvironments in a sector of the San Juan Raya Formation during Early Cretaceous time. The results indicate that the paleoenvironmental model for the study area corresponds to a shallow marine, open-coast, storm-dominated clastic system, characterized by several variations in subenvironments, from foreshore to offshore. Along a measured composite column of about 765.5 m in length, nine cycles of transgression-regression were identified, with the shallowest stage at the 200 and 500 m levels and the deepest conditions at 300, 400 and 765.5 m in the column.

PHENETIC RELATIONSHIPS BETWEEN JUAN FERNANDEZ AND CONTINENTAL CHILEAN SPECIES OF SOPHORA (FABACEAE BASED ON FLAVONOID PATTERNS  

Directory of Open Access Journals (Sweden)

Full Text Available Twenty-three flavonoids were isolated from the leaves of two species of Sophora (Fabaceae from the Juan Fernández Islands (S. fernandeziana and S. masafuerana, two related species from continental Chile (S. macrocarpa and S. microphylla and one sample from New Zeland (S. microphylla. A phenetic analysis was used to evaluate chemical similarities. Flavonoid profiles suggest that Chilean and New Zealand populations of S. microphylla are most closely related to each other. Sophora masafuerana appears most closely related to S. microphylla and this pair of species is also fairly closely related to S. fernandeziana. S. macrocarpa is more distantly related to the cluster of other species. The results suggest that the two Juan Fernandez endemic species are derived from two separate introductions. The exact origin of S. masafuerana remains unclear, as the evidence does not enable us to distinguish between or clarify its possible relationships with New Zealand or South American populationsSe aislaron veintitrés flavonoides de hojas de dos especies de Sophora (Fabaceae endémicas de Juan Fernández: S. fernandeziana y S. masafuerana, dos especies de Chile continental, S. microphylla y S. macrocarpa y una población de S. microphylla proveniente de Nueva Zelanda. Se realizó un análisis fenético para evaluar la similitud química entre las especies en estudio. Las dos poblaciones de S. microphylla están más relacionadas entre sí. S. masafuerana está más relacionada a S. microphylla, formando un grupo que se relaciona con S. fernandeziana. S. macrocarpa se ubica algo distante en el fenograma. Los resultados sugieren que las dos especies de Juan Fernández derivaron de dos introducciones.

The accretion of aeolian dust in soils of the San Juan Mountains, Colorado, USA  

Science.gov (United States)

Recent observations suggest a contemporary aeolian dust flux of at least 5-10 g m-2 yr-1 to high-elevation ecosystems of the San Juan Mountains of southwestern Colorado. To better quantify the influence of dust on San Juan soil geochemistry, we used Sr and Nd isotopic mixing models to estimate the total mass of accreted dust in soils of two alpine basins underlain by bedrocks of different geochemical composition. In order to minimize the potentially confounding effects caused by transient soil pools of Sr and Nd, we implemented a sequential leaching procedure that isolates the residual mineral fraction of soils and their putative parent materials, including local saprolite and exogenous dust inputs. Using this approach, we calculated masses of accreted dust in soils, which were similar across the two isotopic tracers and differing local geologies. Long-term rates of dust accretion were estimated to be slightly higher than contemporary rates of dust deposition. We conclude that dust inputs comprise from 10% to 40% of the total soil mass in these ecosystems. Our observations suggest that dust inputs have exerted a primary control on soil development in the San Juan Mountains and have likely influenced the physical and chemical characteristics of soils in this region.

Juan de Fuca slab geometry and its relation to Wadati-Benioff zone seismicity  

Science.gov (United States)

A new model of the subducted Juan de Fuca plate beneath western North America allows first-order correlations between the occurrence of Wadati-Benioff zone earthquakes and slab geometry, temperature, and hydration state. The geo-referenced 3D model, constructed from weighted control points, integrates depth information from earthquake locations and regional seismic velocity studies. We use the model to separate earthquakes that occur in the Cascadia forearc from those that occur within the underlying Juan de Fuca plate and thereby reveal previously obscured details regarding the spatial distribution of earthquakes. Seismicity within the slab is most prevalent where the slab is warped beneath northwestern California and western Washington suggesting that slab flexure, in addition to expected metamorphic dehydration processes, promotes earthquake occurrence within the subducted oceanic plate. Earthquake patterns beneath western Vancouver Island are consistent with slab dehydration processes. Conversely, the lack of slab earthquakes beneath western Oregon is consistent with an anhydrous slab. Double-differenced relocated seismicity resolves a double seismic zone within the slab beneath northwestern California that strongly constrains the location of the plate interface and delineates a cluster of seismicity 10 km above the surface that includes the 1992 M7.1 Mendocino earthquake. We infer that this earthquake ruptured a surface within the Cascadia accretionary margin above the Juan de Fuca plate. We further speculate that this earthquake is associated with a detached fragment of former Farallon plate. Other subsurface tectonic elements within the forearc may have the potential to generate similar damaging earthquakes.

El análisis toma como punto de partida el concepto de transparencia y opacidad morfológica, en virtud de que la formación de palabras en este poema estará condicionada, entre otras cosas, por el hecho de que el lector pueda identificar la palabra base de la licencia poética, situación que le permitirá determinar el significado de la misma. Además, algunas de estas licencia poéticas rivalizarán con palabras establecidas de la lengua, de manera que la licencia poética no será bloqueada, porque a partir de la transparencia Juan Gelman logrará restituir los significados básicos o prototípicos que las palabras establecidas han dejado de expresar. Finalmente, se muestra cómo se favorece la argumentación literaria con el empleo de herramientas propias de la descripción lingüística. Abstract in english In this paper, the author uses the tools of linguistics and morphology to describe formally and semantically the poetic licenses and archaisms found in the poem "Comentario VII" by Juan Gelman: that is, those occasional words coined by Gelman with emotional and poetic purpose, as well as words that [...] have become obsolete but have found themselves revitalized in his poetry. The analysis takes as its starting point the concept of morphological transparency and opacity, through which the formation of words in the poem is conditioned, among other things, by the fact that the reader can identify the base word of poetic license, an identification that allows him to determine the base word's meaning. Similarly, some of these words will contend with both formally and semantically established words in such a way that poetic license will not be blocked, as through transparency Gelman will succeed in restoring basic or prototypical meanings that words no longer express. Finally, the author shows how literary argument is supported by the use of tools of linguistic description.

Juan de Fuca Plate Ridge-to-Trench Experiment: initial results from active source seismic imaging of the Juan de Fuca plate and Cascadia fore-arc (Invited)  

Science.gov (United States)

Active source seismic data were acquired during the Juan de Fuca Ridge-to-Trench experiment (June-July 2012) to characterize the evolution and structure of the Juan de Fuca plate from formation at the ridge, through evolution in the plate interior, to subduction at the Cascadia trench. The survey provides plate-scale images of the sediments, crust, and shallowest mantle along two ridge-perpendicular transects, one extending from Axial seamount to the Oregon margin near Hydrate Ridge and the other from near Endeavour segment to Grays Harbor offshore Washington. In addition, a 450 km long trench-parallel line ~10 km seaward of the Cascadia deformation front was acquired to characterize variations in plate structure along the margin. Coincident long-streamer (8 km) multi-channel seismic (MCS) and wide-angle ocean bottom seismometer (OBS) data were collected along each transect. Using these data, our current investigations focus on the properties of the thick sediment blanket covering the Juan de Fuca plate and evidence for fluid flow at the deformation front, crustal structure within the plate interior and near the deformation front, and tracking the downgoing plate beneath the margin. Highlights include the discovery of numerous pockmarks on the seafloor providing evidence of active fluid flow up to 60 km west of the deformation front. Along the Oregon transect, a bright decollement horizon is imaged at ~1sec twtt above basement whereas at the Washington margin, protothrusts of the deformation front reach to the top of the oceanic crust. Variations in sediment properties are documented within the margin-parallel transect with changes in the stratigraphic level of decollement. While crustal thickness is quite uniform along the margin (~ 6 km), variations in crustal reflectivity and in shallowest mantle velocities are observed over ~30-50 km length scales that could be related to structural variations in the Cascadia subduction zone. Further landward, the top of the downgoing plate is imaged intermittently beneath the Oregon margin to within ~30 km of the coast. Patches of shallower bright reflectivity possibly related to the seaward edge of the Siletzia terrane are also imaged. A piggyback 3D onshore/offshore tomography experiment indicates considerable along-strike structural variation along this segment of the subduction zone. West of the deformation front, crustal-scale faults transect the downgoing plate along the Oregon transect. Seismic layer 2A is well imaged for most of this transect but disappears within 15 km of the deformation front, possibly linked to enhanced alteration or deformation associated with plate bending. An overview of these results will be presented here with details provided in companion presentations of the co-authors at this meeting.

Taxonomy and biogeography of the coastal fishes of Juan Fernández Archipelago and Desventuradas Islands, Chile / Taxonomía y biogeografía de los peces costeros del Archipiélago de Juan Fernández y de las islas Desventuradas, Chile

Full Text Available SciELO Chile | Language: English Abstract in spanish Las islas Desventuradas (San Félix y San Ambrosio) y del Archipiélago de Juan Fernández (Robinson Crusoe y Alejandro Selkirk) son islas oceánicas de origen volcánico ubicadas en el Pacífico Sudeste, frente a Chile. Sobre la base de material recolectado desde 1997 hasta la fecha, revisiones de colecc [...] iones de las expediciones del R/V Anton Bruun y actualizaciones taxonómicas, la fauna de peces litorales del Archipélago de Juan Fernández y las islas Desventuradas tienen un total de 52 especies, con 41 y 43 especies, respectivamente. Los peces costeros endémicos de Juan Fernández son solamente cinco (12,2%) y tres son las especies registradas aquí como nuevas para las islas (Gymnothorax cf. obesus, Gnathophis sp., Suezichthys sp.). Las Desventuradas tienen solamente dos especies endémicas (4,6%) y cuatro son los nuevos registros (Scorpaenodes englerti, Maxillicosta reticulata, Suezichthys sp., Aseraggodes bahamondei). El reducido número de especies endémicas para Juan Fernández comparado con trabajos previos (15 especies) se debe a que muchas resultaron ser endémicas de ambos grupos de islas (22 especies = 42,3% total peces litorales), apoyando la propuesta que ambos grupos de islas debieran formar una sola unidad biogeográfica. La extensión oriental de la región Indo Pacífico Oeste para incluir la cordillera de Nazca, las islas Desventuradas y Juan Fernández encuentra apoyo en este trabajo. La afinidad zoogeográfica entre las Desventuradas y las islas del Pacífico Oeste (Isla de Pascua hasta Australia) incluye 16 especies, agregando cinco nuevos registros a listas anteriores. Filogenias de tres géneros señalan un centro de origen en el Pacífico Oeste, con uno o más eventos de dispersión hacia las islas Desventuradas y Juan Fernández. Este patrón de dispersión puede repetirse en otros siete géneros de pocas especies y relativamente restringidas en distribución. Solo una filogenia (Odontesthes) propone un origen continental con una dispersión hacia el Oeste, sin embargo otros tres géneros parecen tener este mismo patrón de dispersión. Abstract in english The Desventuradas Islands (San Félix and San Ambrosio) and Juan Fernández Archipelago (Robinson Crusoe and Alejandro Selkirk) are oceanic islands of volcanic origin located in the southeastern Pacific off Chile. Based on new material collected since 1997, revision of the R/V Anton Bruun expeditions [...] collections, and a taxonomic update, the coastal fish fauna of Juan Fernández Archipelago and Desventuradas Islands found a total of 52 species, with 41 and 43 species, respectively. The number of coastal fish species recorded herein as endemic for Juan Fernández is only five (12,2%) and three species are new records (Gymnothorax cf. obesus, Gnathophis sp., Suezichthys sp). The Desventuradas Islands have only two endemic species (4,6%) and four species are new records (Scorpaenodes englerti, Maxillicosta reticulata, Suezichthys sp., Aseraggodes bahamondei). The reduced number of endemic species for the Juan Fernández Islands as compared with previous accounts (15 species) is the result that more species were found to be endemic to both islands groups (22 species = 42,3% all coastal fishes), suggesting these two island groups should be considered a single biogeographic unit. The eastern extension of the Indo West Pacific Region to include the Nazca Ridge, Desventuradas and Juan Fernández Islands is supported herein. The zoogeographical affinities between Desventuradas and western Pacific Islands (Easter Island to Australia), includes 16 species, adding five new species to previous lists. Relationships of three genera indicate a Western Pacific origin with one or more dispersal events to the Desventuradas and Juan Fernández Islands. Another seven genera, with relatively few species and restricted distribution, may have this same pattern. Only one phylogenetic study indicates a continental origin with a westward dispersal (Odontesthes), however another thr

Project "Conservation, Restoration, and Development of the Juan Fernández islands, Chile" / Proyecto conservación, restauración y desarrollo de las islas Juan Fernández, Chile  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: English Abstract in spanish Las islas Juan Fernández albergan una de las floras más interesantes del planeta desde el punto de vista científico. Aunque están protegidas como Parque Nacional y Reserva Mundial de la Biosfera, más de 400 años de intervención humana han dejado una profunda huella en sus comunidades de plantas nati [...] vas. Los repetidos incendios, sobreexplotación de especies y la introducción de plagas animales y vegetales, han colocado al 75 % de la flora vascular endémica bajo amenaza de extinción. En 1997, la Corporación Nacional Forestal de Chile (CONAF) dio inicio a un ambicioso proyecto, cuyo propósito es recuperar este ecosistema de alta complejidad a través de un enfoque socio-ecológico. Juan Fernández constituye un caso interesante, debido a que la población local (600 personas) prácticamente vive dentro del parque, por lo que no es posible excluir al humano de los programas de conservación. Segundo, el relativamente pequeño tamaño del archipiélago (100 km²) permite la observación de los efectos de cualquier modificación en el ecosistema en pequeñas escalas en el tiempo y el espacio. Tercero, la biota nativa e introducida se relaciona de tal manera que la modificación de la abundancia de una especie por acción humana puede provocar resultados inesperados en otras especies no consideradas blanco. El proyecto comprende principalmente programas que buscan controlar o erradicar algunas de las plagas animales y vegetales, adopta medidas activas para conservar y restaurar la flora, así como también inserta al humano en los planes de conservación. En este trabajo se da a conocer la problemática general del parque, la estrategia que se ha seguido para resolver estos problemas, así como también se informan los primeros resultados. Este proyecto ilustra la complejidad para realizar labores de conservación en una situación práctica, con variadas y complejas interrelaciones, y con vacíos en el conocimiento ecológico. Por lo tanto, puede servir como modelo para realizar programas similares en otros lugares Abstract in english From a scientific point of view, the Juan Fernández islands contain one of the most interesting floras of the planet. Although protected as a National Park and a World Biosphere Reserve, 400 years of human interference have left deep traces in the native plant communities. Repeated burning, overexpl [...] oitation of species, and the introduction of animal and plant plagues have taken 75 % of the endemic vascular flora to the verge of extinction. In 1997, Chile's national forest service (Corporación Nacional Forestal, CONAF) started an ambitious project, whose objective is the recovery of this highly complex ecosystem with a socio-ecological focus. Juan Fernández makes an interesting case, as the local people (600 persons) practically live within the park, therefore impeding the exclusion of the people from any conservation program. Secondly, the relatively small size of the archipelago (100 km²) permits the observation of the effects of whatever modification in the ecosystem on small scales in time and space. Thirdly, the native and introduced biota are interrelated in such a way that human-caused changes in one species population may provoke unexpected results amongst other, non-target species. The project mainly deals with the eradication or control of some animal and plant plagues, the active conservation and restoration of the flora and the inclusion of the local people in conservation planning. This article presents the park's general problems, the strategy proposed to resolve them as well as some preliminary results. This project shows the complexity of the conservation activities in practice, with diverse and complex interrelations and gaps in ecological knowledge. In this respect, the project may well serve as a model for similar programs in other places

Estimates of ground-water recharge from precipitation to glacial-deposit and bedrock aquifers on Lopez, San Juan, Orcas, and Shaw islands, San Juan County, Washington  

Science.gov (United States)

An important source of fresh water on Lopez, San Juan, Orcas, and Shaw Islands in San Juan County off the northwestern coast of Washington is glacial-deposit and bedrock aquifers. Two methods were used to estimate recharge from precipitation to the water tables on the islands. A daily near-surface water-balance method, the Deep Percolation Model (DPM), was used to simulate water budgets for the period October 1, 1996, through September 30, 1998 (water years 1997-98) for six small drainage basins?three on Lopez Island and one each on San Juan, Orcas, and Shaw Islands. The calibrated soil and subsoil parameters from the DPM for each small basin were then used in island-wide applications of the DPM where the direct runoff component (which is not available on an island-wide basis) was simulated, rather than input, and calibration was not required. A spatial distribution of annual recharge was simulated for each island, with island averages of: Lopez Island, 2.49 inches per year; San Juan Island, 1.99 inches per year; Orcas Island, 1.46 inches per year; and Shaw Island, 1.44 inches per year.A chloride mass-balance method that requires measurements of atmospheric chloride deposition, precipitation, streamflow, and chloride concentrations in ground water was used to estimate recharge to the glacial-deposit aquifers of Lopez Island. Only average recharge could be estimated using this method rather than area-specific recharge. Average recharge for Lopez Island estimated by this method was only 0.63 inch per year. The range of chloride concentrations in ground-water samples from selected wells indicates that the average recharge in areas of glacial deposits is between 0.29 and 1.95 inches per year. Recharge simulated using the DPM for two drainage basins on Lopez Island overlain by glacial deposits are 2.76 and 2.64 inches per year. Sources of chloride in ground water other than from the atmosphere would cause the recharge estimated by the chloride mass-balance method to be less than the actual recharge, therefore these estimates may represent lower limits which are, at least, consistent with the higher simulated recharge from the DPM. The average island-wide recharge is most closely related to the amount of area overlain by glacial deposits. Thus, even though Lopez Island receives the least precipitation, it has the most recharge per square mile because it proportionally has the largest area overlain by glacial deposits. Recharge simulated by the DPM for areas of shallow to outcropping bedrock generally were less than 1.5 inches per year, but recharge simulated in areas of glacial deposits ranged from less than 0.5 to 3 inches per year, with recharge as high as 9 inches per year in some small areas.

Darriwilian bryozoans from the San Juan Formation (Ordovician), Argentine Precordillera / Briozoos darriwilianos de la Formación San Juan (Ordovícico) de la precordillera argentina  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: English Abstract in spanish Se ha realizado un estudio taxonómico detallado de la fauna de briozoos de los niveles superiores (Darriwiliano) de la Formación San Juan en las secciones de Talacasto y Cerro Viejo, Precordillera Argentina. Se describen tres géneros y se definen dos nuevas especies: Lamottopora multispinosa sp. nov [...] ., Aostipora sanjuanensis sp. nov. y Phylloporinidae sp. indet. Se discute el significado paleoecológico de la fauna de briozoos. Los briozoos ramosos como Lamottopora y Aoistopora dominan en la sección de Talacasto. Algunas colonias vivieron fijadas directamente sobre el sustrato, aunque también aparecen como epibiontes sobre la superficie de esponjas, que son muy abundantes en este intervalo. En la sección de Cerro Viejo los briozoos se encuentran mayoritariamente adheridos a la superficie de las esponjas, mientras que algunos fragmentos de briozoos ramosos, incluyendo dos colonias del briozoo reticulado Phylloporinidae sp. indet, aparecen en el sedimento. La presencia de estas formas delicadas en el Cerro Viejo es una nueva evidencia de la baja energía del agua como fue sugerido para estos niveles. En las calizas de la Formación San Juan sólo el género laminar Nicholsonella aparece en niveles algo más antiguos (Floiano). Esta baja diversidad muestra un desajuste con las curvas globales de diversidad del grupo. La primera radiación local (géneros), descripta en esta contribución, es también significativamente menor y muestra un desacople con la diversificación que experimenta el grupo para este mismo intervalo temporal en otras regiones. Abstract in english A detailed study is carried out on the taxonomy of the bryozoan fauna from the upper levels of the San Juan Formation (Darriwilian) in the Talacasto and Cerro Viejo sections, Argentinean Precordillera. Three bryozoan genera are described and two new species are erected: Lamottopora multispinosa sp. [...] nov., Aostipora sanjuanensis sp. nov., and Phylloporinidae sp. indet. The paleoecological significance of the bryozoan fauna is discussed. The ramose bryozoans Lamottopora and Aostipora dominate in the Talacasto section. Some colonies probably lived attached directly to the substrate, while others occur attached to the surface of the abundant sponge fauna in the section. The majority of bryozoans at the Cerro Viejo section occur as epibionts, with bases attached to the surface of sponges. Bryozoans collected in the matrix are scarce compared to the Talacasto section, and comprise a few fragments of ramose bryozoans and two small fragments of the reticulate Phylloporinidae sp. indet were recorded exclusively in this locality. The presence of this delicate form in Cerro Viejo is further evidence of the quiet water conditions suggested for these levels. Only the laminar form Nicholsonella occurs in slightly older levels (Floian) of the San Juan Formation. The low diversity recorded here shows a slight decoupling with the global pattern. The first local radiation (three genera) is minor compared with the important radiation that the phylum experienced elsewhere.

Die Geschicke von Don Juan Tenorio in Barcelona: Skizze einer ignorierten Rezeption [The story of Don Juan Tenorio in Barcelona: Outline of a disregarded reception  

Directory of Open Access Journals (Sweden)

Full Text Available Against the common opinion that starting from Madrid (in 1844 José Zorilla’s Don Juan Tenorio began his triumph as an obligate and catharically cited play for All Soul’s Day soon after its premiere, its integration from 1847 onwards into the scenic ritual, that at that time had long since then been established in Barcelona, is documented here as well as its changeful development, that strongly differs from the development in Madrid, until it came to an end in 1974. This not only includes the many Spanish and especially Catalan theatre plays that derive from it and were represented alongside with it (variations, sequels, parodies, humoresques but also its media utilisation for cinematographs, films and trivial reading (penny dreadful. The discussion accounts for cultural traditions, ideal positions and ethnopolitical and linguistic political attitudes as factors for the reception process.

LA CAÍDA DE UNA ARTESANÍA: CESTERÍA EN SAN JUAN GUELAVIA, OAXACA THE COLLAPSE OF A CRAFT: BASKETMAKING IN SAN JUAN GUELAVIA, OAXACA  

Directory of Open Access Journals (Sweden)

Full Text Available Los artesanos oaxaqueños son célebres por la calidad de sus trabajos, el éxito de sus negocios y la capacidad de sus productos para trascender en el espacio y el tiempo. Los tejedores de algodón y textiles de lana, los fabricantes de cerámica de barro y más recientemente talladores de madera, que hacen alebrijes (animales de madera pintada, producen artículos que son comprados y vendidos en el mercado internacional y son exhibidos mundialmente en las colecciones de museos. Sin embargo, hay artesanías en Oaxaca que no son viables en el mercado y no aparecen en colecciones internacionales. En este documento examinamos la producción de canastas en la comunidad de San Juan Guelavia. Argumentamos que la caída en el mercado refleja tres cambios críticos: primero, una disminución en el uso local; segundo, un alza en los costos de producción; y tercero, una falta de apoyo de exportadores y una incapacidad para involucrarse en el mercado de exportación.Oaxacan artisans are celebrated for the quality of their work, their business success, and the ability of their goods to transcend space and time. Weavers of cotton and woolen textiles, potters, and most recently wood carvers who make alebrijes (painted wooden animals produce goods that are bought and sold on the international market and appear in museum collections world-wide. Nevertheless, there are crafts in Oaxaca that are not viable in the current market and that do not show up in international collections. In this paper, we examine one such craft: basket making in the community of San Juan Guelavia. We argue that the decline in the market for these goods reflects several changes: first, a decline in local use; second, a rise in the costs of production; and third, a lack of support by exporters and an inability to engage the export or tourist markets. In response, local producers have moved into wage labor (locally and through migration to secure their incomes.

Primeras dataciones del lago holoceno tardío de Zonda, San Juan First datings for the Late Holocene lake of Zonda, San Juan  

Directory of Open Access Journals (Sweden)

Full Text Available Se dan a conocer las primeras edades numéricas de los depósitos lacustres vinculados al río San Juan, que afloran en la depresión de Zonda y que corresponden al Holoceno tardío. Se determinaron cuatro unidades de depósitos cuaternarios correspondientes a: depósitos de bajada, fluviales antiguos, lacustres, y fluviales actuales aterrazados. De éstos, los depósitos lacustres fueron datados en los bordes occidental y oriental de la depresión de Zonda, que sobresalen entre los depósitos de las bajadas oriental de la sierra de Zonda, al oeste, y occidental de la sierra Marquesado, al este. De acuerdo a las dataciones radiocarbónicas (14C y relaciones estratigráficas, el episodio lacustre-palustre tuvo lugar en el Holoceno tardío (2.840 ± 80 AP, permaneciendo durante más de 1.000 años. Hacia el borde oriental del valle, la datación arroja una edad de (1.890 ± 80 AP. Este cuerpo de agua fría y dulce, se habría extendido en una superficie igual o superior a 750 km², ocupando gran parte del valle de Zonda y Ullum.We present numerical ages of lacustrine deposits associated with the San Juan River, which emerge in the depression of Zonda. Four different Quaternary units were identified from downstream bajada deposits, ancient fluvial deposits, lacustrine deposits and present fluvial terrace deposits. The lacustrine sediments were dated on both sides of the valley in the outcrops located in the distal portion of the eastern slope of the sierra de Zonda and the western slope of the Marquesado range. According to the dating and stratigraphic relationships, this lake-swamp episode would have occurred in the late Holocene (2,840 ± 80 BP, remaining around 1,000 years. Towards the eastern side of the valley, the dating yields an age of (1,890 ± 80 AP. The area of the cold and freshwater body would have been around 750 km² covering a great part of the Zonda and Ullum valley.

Un realismo de lo irreal: la imaginación material en la obra de Juan José Saer / Realism of the Unreal: Material Imagination in Juan José Saer's Works  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish Este trabajo propone una lectura de la narrativa de Juan José Saer desde la fenomenología de Gaston Bachelard. El análisis recae sobre tres novelas que se consideran representativas del autor argentino y consiste en una indagación de lo que Bachelard, en sus análisis poéticos, llama imaginación mate [...] rial. Tal noción permite reinscribir la interrogación sobre el realismo saeriano, pensado en general por la crítica en términos de representación y relacionado con un problema tópico de esta narrativa como es el de la percepción. La lectura no postula una simple traslación metodológica, sino que encuentra su potencial en el problema que implica el abordaje de una narración postulada como realista desde la fenomenología microscópica bachelardiana, elaborada para la poesía o para narraciones fantásticas. No se trata de un problema metodológico, sino interno a la narrativa saeriana: es la tensión entre la liberación de la imaginación material en una narración regulada por una imaginación formal que es la de la estructura novelística y las prerrogativas del verosímil realista. Abstract in english This article proposes to read Juan José Saer's narrative from the perspective of Gaston Bachelard's phenomenology. The analysis focuses on three novels, which are considered to be representative of the Argentine author, and inquires into which Bachelard calls material imagination in his poetic analy [...] ses. This notion allows to hypothesize about Saer's realism, which has been conceived in terms of representation and related to the topic of perception, especially in this narrative. This reading does not propose a simple methodological transfer but finds its potential in the realistic approach to a piece of writing carried out from the microscopic phenomenology of Bachelard, who studied mainly poetry and fantastic narratives. It is about an inherent problem to Saer's narrative, that is to say, the tension between liberation of material imagination in a narrative regulated by formal imagination, which is related to the novel structure and to the prerogatives of realistic verisimilitude.

El retablo mayor del convento de Santa Isabel de los Reyes de Toledo: nuevas aportaciones a la obra de Andrés Sánchez, Juan Bautista Monegro, Juan Sanchez Dávila y Pedro de Cisneros el Mozo  

Directory of Open Access Journals (Sweden)

Full Text Available Documents studied here and the analysis of the work demonstrate that the main altarpiece of Santa Isabel de los Reyes is one of the most outstanding examples of Toledan 16th-century sculpture. Commissioned in 1570, it was completed by 1572, according to the inscription on the altarpiece, which until now has remained anonymous. The discovery of two payment orders demonstrate that it was created by the architect and sculptor Juan Bautista Monegro, the woodcarver Andrés Sánchez and the painter-gilders Juan Sánchez Dávila and Pedro de Cisneros el Mozo, to whose respective catalogues this work should be added, particularly that of Juan Bautista Monegro. From the formal and stylistic point of view, the reliefs and statues by Monegro can be related to the best classicism of the Leoni.

Las pruebas documentales aquí aportadas y el estudio de las formas artísticas, demuestran que el retablo mayor de Santa Isabel de los Reyes es una de las obras más sobresalientes de la escultura toledana del siglo XVI. Encargado antes de 1570, estaba concluido, como señala el epígrafe que preside el propio retablo, en el año 1572, siendo abadesa María de Guzmán. Ha permanecido como anónimo hasta la localización de dos órdenes de pago que lo documentan como obra del arquitecto y escultor Juan Bautista Monegro, del entallador Andrés Sánchez y de los pintores-doradores Juan Sánchez Dávila y Pedro de Cisneros el Mozo a cuyos respectivos catálogos debe incorporarse como obra destacada, especialmente en lo tocante al estudio de Juan Bautista Monegro, que fue el de mayor trascendencia de los cuatro. Desde el punto de vista formal y estilístico, sus relieves y esculturas se pueden relacionar con lo mejor del clasicismo de los Leoni.

The Crownpoint and Churchrock uranium deposits, San Juan Basin, New Mexico: An ISL mining perspective  

International Nuclear Information System (INIS)

The Crownpoint and Churchrock uranium deposits, San Juan Basin, New Mexico are currently being developed by Uranium Resources, Inc. (URI) and its subsidiary Hydro Resources, Inc. (HRI) with an anticipated start-up in 1998. Both deposits will be developed using advanced in situ leach (ISL) mining techniques. URI/HRI currently has about 14,583 t U (37.834 million pounds U_3O_8) of estimated recoverable reserves at Crownpoint and Churchrock. at a cost less than $39/kg U ($15/lb U_3O_8). The uranium endowment of the San Juan Basin is the largest of any province in the USA. In March, 1997, a Final Environmental Impact Statement (FEIS) for the Crownpoint and Churchrock sites was completed by the Nuclear Regulatory Commission which recommends the issuance of an operating license. The FEIS is the culmination of a 9 year effort to license and develop the deposits. The Westwater Canyon Member of the Jurassic Morrison Formation is an arkosic, fine to coarse grained sandstone bounded by near basinwide confining clays deposited in a wet alluvial fan environment within the San Juan Basin. The primary, trend-ore deposits are hosted by the Westwater Canyon Member as humate-rich, syngenetic tabular deposits which were subsequently remobilized into roll fronts. Since deposition in the Jurassic, two phases of remobilization have occurred in the basin causing the formation of in situ leach amenable monometallic uranium rolls free of organic debris. Following in situ mining, ground water restoration of the Crownpoint and Churchrock mines is required to provide a water quality consistent with pre-mining baseline conditions. The development of in situ mining offers an environmentally sound and cost-effective method for uranium extraction. URI/HRI anticipates a production of 385-1,156 Tonnes U/year (1-3 million pounds U_3O_8) from the New Mexico properties. (author)

Community-based enterprises and the commons: The case of San Juan Nuevo Parangaricutiro, Mexico  

Directory of Open Access Journals (Sweden)

Full Text Available Commons scholarship has tended to focus on the administration and use of commons by individuals and households and less so on collective enterprises that extract, transform and market what they harvest from the commons. In this paper, we consider Nuevo San Juan, a Mexican case that is well known in the community forestry and commons literature. In San Juan, indigenous community members who hold the rights for the commons are also the members of the enterprise that transforms and markets goods from the commons. We argue that such a strategy is one way to confront internal and external pressures on a commons. We draw upon the transcripts of 40 interviews undertaken during 2006 which are analyzed using a framework developed from the social, community-based and indigenous enterprise literature. Our goal was to utilize this framework to analyze the San Juan Forest Enterprise and understand its emergence and formation as a long-standing community-based enterprise that intersects with a commons, and thereby identify factors that increase chances of success for community enterprises. We found that by starting from the community-based and indigenous enterprise literature and using that literature to engage with thinking on commons, it was possible to consider the enterprise from the perspective of a regulatory framework rather than from the poles of dependency and modernization theories in which much commons work has been based. Enterprise and commons intersect when both are guided by core cultural values and the enterprise can become a new site for the creation of social and cultural cohesion. We also found that there were a number of necessary conditions for commons-based community-enterprises to retain internal and external legitimacy, namely: (1 leadership representative of the broad social mission rooted in the customary institutions, values and norms of the community; (2 accountability of enterprise leaders to the memberships they represent; and (3 a close adherence to the political goals of the community as a whole.

Abstract in english The article reconstitutes the social thinking in health by Argentine physician and sociologist Juan César García (1932-1984), analyzing the main publications approaching his work and activities. The article situates his thinking in the two fields that marked his production: social medicine and the s [...] ocial sciences from the 1960s to the late 1980s. The article highlights his work with the Pan American Health Organization and his perspective of analyzing social medicine and the social sciences by relating them not only to the Latin American historical, social, economic, and political context, but also to historical materialism: linking medicine to the social structure; the influence of the social structure on the production and distribution of diseases; internal analysis of the production of medical services; and the relationship between training of health personnel and the medical field. As demonstrated, even today his work can be a reference for the discussion of such themes as medical education, health personnel training, the role of science and technology, the social sciences in medical education, and historical aspects of public health.

Abstract in english The article reconstitutes the social thinking in health by Argentine physician and sociologist Juan César García (1932-1984), analyzing the main publications approaching his work and activities. The article situates his thinking in the two fields that marked his production: social medicine and the s [...] ocial sciences from the 1960s to the late 1980s. The article highlights his work with the Pan American Health Organization and his perspective of analyzing social medicine and the social sciences by relating them not only to the Latin American historical, social, economic, and political context, but also to historical materialism: linking medicine to the social structure; the influence of the social structure on the production and distribution of diseases; internal analysis of the production of medical services; and the relationship between training of health personnel and the medical field. As demonstrated, even today his work can be a reference for the discussion of such themes as medical education, health personnel training, the role of science and technology, the social sciences in medical education, and historical aspects of public health.

Intestinal protozoan and helminth infections in the Municipality San Juan y Martínez, Pinar del Río, Cuba.  

Science.gov (United States)

A cross-sectional study was carried out to determine the prevalence of intestinal parasitic infections and the intensity of soil-transmitted helminths (STHs) among children who attend the educational centres of San Juan y Martinez, Cuba. Ascaris lumbricoides, Blastocystis hominis and Giardia lamblia were the most common parasites found, with prevalence rates of 40.5%, 38.5% and 25%, respectively. In total, 91% of children harboured at least one type of intestinal parasite. The rates and intensity of intestinal parasitic infections found permit us to speculate that the conditions that predispose to acquire intestinal protozoan and STH infections persist in this municipality.

PRELIMINARY GEOID MODEL IN SAN JUAN PROVINCE: A CASE STUDY IN THE ANDES  

DEFF Research Database (Denmark)

A high-resolution and high-precision detailed gravimetric geoid has been computed for San Juan province in Argentina, ranging from 27 degrees S to 34 degrees S in latitude and 72 degrees W to 65 degrees W in longitude. The gravimetric geoid was calculated using the RTM method, a multiband spherical Stokes Fast Fourier Transformation, and the removerestore technique for the spherical harmonic reference field and the terrain. As an external evaluation, the gravimetric quasigeoid/geoid was compared to the geoid heights obtained from 90 GPS/levelling points available for the province. Finally, a GPS-tailored local geoid, which fits the GPS observations, was computed.

DINÁMICA ESPACIO-TEMPORAL DEL HUMEDAL JUAN AMARILLO ENTRE 1950 - 2005  

Directory of Open Access Journals (Sweden)

Full Text Available

RESUMEN

Se analizó la dinámica del Humedal Juan Amarillo durante el periodo comprendido entre los años 1950-2005. Los resultados muestran que la configuración paisajística del ecosistema ha cambiado notoriamente con una tendencia al incremento en el número, tamaño y tipo de parches. Igualmente se presentan diferencias estructurales importantes entre los diversos periodos de tiempo analizados, ocasionados principalmente por la disminución y desaparición de espejos de agua y el aumento de pasto kikuyo (Pennisetum clandestinum. En cuanto al arreglo espacial de los elementos paisajísticos, no sucedieron cambios importantes en los patrones de distribución espacial de los elementos paisajísticos del humedal. De acuerdo con la dimensión fractal, los elementos del paisaje presentan dos tendencias en cuanto a su complejidad: los elementos introducidos poseen las formas más complejas y los elementos propios del ecosistema tienen formas más regulares. Finalmente, la dinámica del humedal fue modelada con el fin de interpretar cómo las múltiples interacciones entre los elementos paisajísticos han influido en la configuración del humedal a lo largo del tiempo.

Palabras clave: Humedal Juan Amarillo, estructura, composición, dimensión fractal.


ABSTRACT

The dynamics of Juan Amarillos’ wetland were analyzed during 55 year between 1950 and 2005. The results showed that the landscape configuration of the ecosystems has dramatically changed within a trend to increase in number, size, and patch type. Likewise, important structural differences came up between the various periods in question; such differences appear to be related to the reduction and disappearance of the pond and the significant increase of the non native kikuyo grass (Pennisetum clandestinum. Regarding the spatial arrangement of the landscape elements, there were no significant changes in spatial distribution patterns. According to the fractal dimension and complexity, the landscape elements showed two trends: non native and man-made elements are more complex in shape, whereas native elements showed more regular shapes. Finally, the wetland dynamics were modelled with the aim of construing how the multiple interactions of the landscape elements have influenced the wetland configuration over time.

Key words: Juan Amarillo Wetland, structure, composition, fractal dimension.

Henry Sigerist and the history of medicine in Latin America: his correspondence with Juan R. Beltran.  

Science.gov (United States)

During the years of World War II, the American Association for the History of Medicine fostered a Pan-American policy aimed at establishing relationships with Latin American historians of medicine. Juan R. Beltrán, professor of history of medicine at the University of Buenos Aires, also pursued an energetic program of academic diplomacy. The correspondence between Henry Sigerist and Beltrán makes manifest that by 1941 good channels of communication were established between Baltimore and Buenos Aires, but the friendly links did not last long. The motives for this can be found in the competing aims of the AAHM and Beltrán, and the pattern of international relationships during the war years. PMID:15764829

Impacts of Urbanization in the Coastal Tropical City of San Juan, Puerto Rico  

Science.gov (United States)

Urban sprawl in tropical locations is rapidly accelerating and it is more evident in islands where a large percentage of the population resides along the coasts. This paper focuses on the analysis of the impacts of land use and land cover for urbanization in the tropical coastal city of San Juan, in the Caribbean island of Puerto Rico. A mesoscale numerical model, the Regional Atmospheric Modeling System (RAMS), is used to study the impacts of land use for urbanization in the environment including specific characteristics of the urban heat island in the San Juan Metropolitan Area (SJMA), one of the most noticeable urban cores of the Caribbean. The research also makes use of the observations obtained during the airborne San Juan Atlas Mission. Surface and rawinsonde data from the mission are used to validate the atmospheric model yielding satisfactory results. Airborne high resolution remote sensing data are used to update the model's surface characteristics in order to obtain a more accurate and detailed configuration of the SJMA and perform a climate impact analysis based on land cover/land use (LCLU) changes. The impact analysis showed that the presence of the urban landscape of San Juan has an impact reflected in higher air temperatures over the area occupied by the city, with positive values of up to 2.5 C, for the simulations that have specified urban LCLU indexes in the model's bottom boundary. One interesting result of the impact analysis was the finding of a precipitation disturbance shown as a difference in total accumulated rainfall between the present urban landscape and with a potential natural vegetation, apparently induced by the presence of the urban area. Results indicate that the urban enhanced cloud formation and precipitation development occur mainly downwind of the city, including the accumulated precipitation. This spatial pattern can be explained by the presence of a larger urbanized area in the southwest sector of the city, and of the approaching northeasterly trade winds. No significant impacts were found in the sea breeze patterns of the city.

Colecistectomía abierta versus laparoscópica: experiencia en el Hospital San Juan de Dios  

Directory of Open Access Journals (Sweden)

Full Text Available La cirugía laparoscópica es una técnica mínimamente invasiva de uso cotidiano en el ámbito mundial. Desde hace quince años, la colecistectomía laparoscópica es un procedimiento seguro y muy valioso a disposición del cirujano. Este estudio tiene como fin comparar los resultados de la colecistectomía laparoscópica en el Hospital San Juan de Dios con la técnica de la colecistectomía abierta ó tradicional. Métodos: Se realizó un estudio retrospectivo de todos los pacientes colecistectomizados desde julio de 1996 a junio de 1999, en el Hospital San Juan de Dios en Costa Rica. Al comparar las dos técnicas quirúrgicas (clásica y laparoscópica, se consideró la evolución posoperatoria y las posibles complicaciones que aparecen posteriores al acto quirúrgico. Además se buscaron las contraindicaciones que dicha técnica pudiese tener. Resultados : Fueron revisados un total de 3193 pacientes colecistectomizados, de los cuales 476 fueron operados por laparoscopia. Se tuvo en éstas menos complicaciones posquirúrgicas y menor estancia posoperatoria que en las colecistectomías abiertas. También se notó una disminución paulatina del tiempo quirúrgico en los actos por laparoscopia. Conclusión: Se comprueban las ventajas de la cirugía invasiva mínima y se documenta que este tipo de abordaje es más seguro y beneficioso para el paciente y para el médico mismo.Justification: Today, laparoscopic surgery as a least invasive technique is widely used in the world. Laparoscopic cholecystectomy is a valuable and safe technique and is has been available to the general surgeon for the last 15 years. In Costa Rica it has become a pretty common procedure with great results but they have not been well studied and documented. This study aims to expose part of the work that takes place at the Hospital San Juan de Dios with laparoscopic cholecystectomy and highlights the results in contrast with those of traditional cholecystectomy. Methodology: Aretrospective study was conducted of all the cholecystectomies performed at the Hospital San Juan de Dios in Costa Rica from July 1996 to June 1999. A comparative analysis between the classic and the laparoscopic approach was completed considering post-operative evolution and postoperative complications. Results: A total of 3193 cholecystectomies, were reviewed, 476 were laparoscopic cholecystectomies, they had less post-operative complications and less post-operative recovery time as opposed to the open cholecystectomies. The study showed further a progressive diminution of the operative time in the laparoscopic group. Conclusions : Laparoscopic cholecystectomy is a safe procedure and it carries several advantages both for thepatient and the surgeon.

History of dredging and filling of lagoons in the San Juan, Puerto Rico  

Science.gov (United States)

Laguna La Torrecilla, Laguna de Pinones, Laguna San Jose, and Laguna del Condado, in the San Juan, Puerto Rico area, are located within a metropolitan area of more than 1 million people. Bathymetric maps made during the study, in 1973, showed that Lagunas La Torrecilla, San Jose, and del Condado have been modified by dredging and filling; whereas, Laguna de Pinones has remained in a near natural state. Laguna La Torrecilla has been dredged to a depth, in places, of about 18 meters, and Lagunas San Jose and del Condado, in places to about 11 meters. Dredging in the San Juan lagoons has been harmful, beneficial, and in a few instances has had little or no noticeable effect on the water quality. Usually, dredging in the connecting canals has been beneficial if the water entering the lagoons through the canals was of better quality than the water in the lagoon. Dredging in the mouths of lagoons has been beneficial; whereas, filling or blocking the mouths has been harmful. (Woodard-USGS)

Creep Transients and Fault Interaction from Repeating Earthquakes Near San Juan Bautista, California  

Science.gov (United States)

Along creeping sections of the San Andreas and other faults, small asperities in the fault zone load and fail in characteristic repeating earthquake sequences which can be used as subsurface creepmeters. Here, we use these virtual creepmeters to examine and compare slip rates on both the northwestern end of the creeping section of the San Andreas Fault near San Juan Bautista and on the nearby sub-parallel Sargent Fault, previously observed to have ~3mm/year of right-lateral creep. While creep on the San Andreas increases dramatically in response to the 1989 Loma Prieta earthquake and takes about ten years to resume interseismic rates, the Sargent shows little immediate response. The Sargent rather exhibits a very gradual increase of activity after the Loma Prieta earthquake, consistent with its generally lower interseismic slip rate and with static stress change models that show only a minor increase in the stress along the Sargent. When the SAF resumes its interseismic rate, it begins creeping coherently in time with the Sargent, indicating a mutual driving force in the system. Background seismicity in gray points, newly discovered repeaters in black circles (inset). Boxes show study area. Stars show epicenters of 1989 Loma Prieta EQ, 1998 San Juan Bautista EQ, and 2004 Parkfield EQ.

Sub-Seafloor Carbon Dioxide Storage Potential on the Juan de Fuca Plate, Western North America  

Energy Technology Data Exchange (ETDEWEB)

The Juan de Fuca plate, off the western coast of North America, has been suggested as a site for geological sequestration of waste carbon dioxide because of its many attractive characteristics (high permeability, large storage capacity, reactive rock types). Here we model CO2 injection into fractured basalts comprising the upper several hundred meters of the sub-seafloor basalt reservoir, overlain with low-permeability sediments and a large saline water column, to examine the feasibility of this reservoir for CO2 storage. Our simulations indicate that the sub-seafloor basalts of the Juan de Fuca plate may be an excellent CO2 storage candidate, as multiple trapping mechanisms (hydrodynamic, density inversions, and mineralization) act to keep the CO2 isolated from terrestrial environments. Questions remain about the lateral extent and connectivity of the high permeability basalts; however, the lack of wells or boreholes and thick sediment cover maximize storage potential while minimizing potential leakage pathways. Although promising, more study is needed to determine the economic viability of this option.

Endeavour Segment of the Juan de Fuca Ridge: One of the Most Remarkable Places on Earth  

Directory of Open Access Journals (Sweden)

Full Text Available Endeavour Segment of the Juan de Fuca Ridge is one of three Integrated Study Sites for the Ridge 2000 Program. It is a remarkable, dynamic environment hosting five major hydrothermal fields, numerous smaller fields, and myriad diffuse-flow sites; magma chambers underlie all fields. Over 800 individual extinct and active chimneys have been documented within the central ~ 15 km portion of the ridge, with some edifices reaching 50 m across and up to 45 m tall. Fluid flow is focused along faults within the rift zone, and seismically active faults along the western axial valley wall have been used by both magmas and upwelling hydrothermal fluids. There is significant chemical heterogeneity in basalt compositions within the axial rift valley, with the greatest diversity occurring near the base of the western axial valley wall where normal, transitional, and enriched type mid-ocean ridge basalts occur within tens of meters of each other. Endeavour is the only site where seismic intensity has been linked directly to heat flux at the individual vent field scale. Installation of the world's first high-power and high-bandwidth cabled observatory at Endeavour via NEPTUNE Canada ensures that new discoveries along the Juan de Fuca Ridge will continue into the future.

Didn’t it matter to him absolutely?: Juan Vilanova and the controversy about tertiary Man  

Directory of Open Access Journals (Sweden)

Full Text Available During the founding period of palaeoanthropology, the postulate about tertiary age of humankind was an outstanding subject. First proposals were based on supposed proofs about ancient lithical industry (eoliths. Some discoveries of human fossil remains complicated that issue, because they were dated as pliocene or oldest. This controversy about so-called «tertiary man» soon arrived to Spain. Juan Vilanova y Piera, palaeontologist and professor at Madrid, dealt with it from an antievolutionist point of view. When a human fossil skeleton, included in the Botet’s collection, with several apparently primitive traits arrived to Valencia from Argentina, Vilanova got reasserted and exposed his ideas about this question more intensely.

Un tema relevante durante el período fundacional de la paleoantropología fue el postulado de la antigüedad terciaria de la humanidad. Las primeras propuestas se basaban en supuestas evidencias de industria lítica (eolitos. La cuestión se complicó con el descubrimiento de diversos fósiles humanos que fueron datados como pliocenos o incluso de mayor antigüedad. Esta polémica sobre el llamado «hombre terciario» llegó pronto a España. El paleontólogo y catedrático de la Universidad Central, Juan Vilanova y Piera, se ocupó extensamente del asunto desde perspectivas antievolucionistas. La llegada a Valencia en 1889, formando parte de la colección paleontológica donada por José Rodrigo Botet, de un esqueleto humano fósil procedente de Argentina que mostraba rasgos aparentes de primitivismo, llevó a Vilanova a reafirmarse y exponer más intensamente sus ideas sobre esta cuestión.

Metal sources of black smoker chimneys, Endeavour Segment Juan de Fuca Ridge: Pb isotope constraints  

Science.gov (United States)

The hydrothermal chimney sulfides and vent cap chimney samples from the Endeavour Segment, Juan de Fuca Ridge, a sediment-starving mid-ocean ridge, display Pb isotope compositions that are indistinguishable from the local basalt, indicating the primary Pb source of sulfides and hydrothermal fluids in Endeavour Segment is basalt. Mean while the relative large Pb isotope composition variation range when compared with other sediment-starving ridges and the anomaly Pb-Pb plot, indicating a sediment component contribution. Results of binary mixing models suggest that the sediment sources contribution is no more than 1%. Combining the Pb isotope data with the chemistry data of hydrothermal fluid within the Endeavour Segment, we suggested the sediment component may locate in the recharge zone, rather than high temperature reaction zone. In addition, the sediment component should have a lower 206Pb/204Pb inferred from the "BF" line which through the densest cluster of Pb isotope data. The lower 206Pb/204Pb sediment component may have a common provenance with that of Middle Valley, providing a new insight on the evolution of the north end of the Juan de Fuca ridge.

Sedimentología y evolución del campo de dunas de Médanos Grandes (provincia de San Juan, Argentina) / Sedimentology and evolution of Médanos Grandes dunefield (San Juan province, Argentina)  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish El campo eólico de Médanos Grandes, sudeste de la provincia de San Juan (Argentina), es uno de los más extensos del país y está formado por distintos tipos de dunas, principalmente transversales y longitudinales. Junto a éstas aparecen grandes megaformas eólicas o draas, de hasta 70 metros de altura [...] y 2000 metros de espaciamiento. El análisis de imágenes satelitales permitió identificar cinco unidades geomorfológicas caracterizadas por geoformas de diferente morfología, tamaño, orientación y dirección de migración. En la unidad geomórfica 1 (UG1) se incluyen draas de crestas transversales (orientadas al azimut 150º), ligeramente sinuosas, con dunas menores sobreimpuestas. La disposición de sus caras de sotavento indica que este conjunto se desarrolló a partir de paleovientos del sudoeste. En la conformación de la UG2 aparecen también draas transversales con dunas asociadas, sin embargo en este caso la orientación de los primeros evidencia paleovientos del noreste. Por otro lado, las dunas menores se disponen de forma oblicua y se habrían, por lo tanto, formado con posterioridad. En la UG3, ubicada en el centro del campo eólico, se destaca la presencia de grandes hoyos de deflación, de hasta 1000 metros de diámetro y 50 metros de desnivel con respecto a las dunas adyacentes. Así mismo, esta unidad se caracteriza por un diseño enrejado de médanos, resultado de la interferencia de las crestas de los draas pertenecientes a las unidades 1 y 2. La UG4 comprende dunas longitudinales, de hasta 40 metros de altura y 150 metros de espaciamiento, que se asocian a pequeñas dunas transversales. La disposición de las dunas longitudinales, junto con la orientación de las caras de sotavento de las formas menores, indican paleovientos del sud-sudeste. Por último, la UG5 está integrada por dunas transversales, barjanoides y longitudinales, que ocupan la periferia del campo eólico aquí estudiado. Constituye la unidad más moderna y respondería también a vientos del sud-sudeste similares a los actuales. Las geoformas eólicas de Médanos Grandes están formadas por arenas finas (X= 2,88 ø), muy bien seleccionadas (s= 0,45 ø) y con distribuciones granulométricas unimodales y simétricas (SK 1 = 0,05). El percentil del 1 % corresponde a la arena mediana (1,87 ø) y el material inferior a 53 ? conforma en promedio el 1,05 % de las muestras. En cuanto a la composición de las arenas predominan los fragmentos líticos (clastos de volcanitas, mayormente ácidas y mesosilícicas, esquistos micáceos, anfibolitas, milonitas, chert, sedimentitas y calizas), junto a moderados porcentajes de feldespatos y muy baja proporción de cuarzo y minerales pesados. La presencia de geoformas con diferente morfología y orientación indica que el sistema eólico de Médanos Grandes es policíclico ya que en su conformación se sucedieron distintos episodios de crecimiento, bajo distintos patrones de vientos. Las unidades geomórficas identificadas pueden ser tentativamente correlacionadas con los estadios climáticos propuestos por autores anteriores para la región pampeana. Finalmente, en la actualidad el campo eólico de Médanos Grandes se halla parcialmente erodado debido a la acción fluvial, constituyendo probablemente un remanente de un extenso sistema eólico que cubría gran parte del valle del Bermejo. Abstract in english Médanos Grandes dunefield, which is located near Vallecito city at the southeast of San Juan province (Argentina), is one of the largest eolian depositional systems in Argentina. It is formed by draas together with transversal and longitudinal dunes and large blowouts. Alluvial plain deposits relate [...] d to San Juan and Bermejo rivers, and the Pie de Palo and Valle Fértil hills sourround the eolian system (Fig. 1). Previous works are very scarce (Groeber, 1937; Rodríguez, 1966), being Regairaz et al. (1987) the ones who described the dunefield as made up of complex dunes. The present study can be divided

LA CAÍDA DE UNA ARTESANÍA: CESTERÍA EN SAN JUAN GUELAVIA, OAXACA / THE COLLAPSE OF A CRAFT: BASKETMAKING IN SAN JUAN GUELAVIA, OAXACA

Sin embargo, hay artesanías en Oaxaca que no son viables en el mercado y no aparecen en colecciones internacionales. En este documento examinamos la producción de canastas en la comunidad de San Juan Guelavia. Argumentamos que la caída en el mercado refleja tres cambios críticos: primero, una disminución en el uso local; segundo, un alza en los costos de producción; y tercero, una falta de apoyo de exportadores y una incapacidad para involucrarse en el mercado de exportación. Abstract in english Oaxacan artisans are celebrated for the quality of their work, their business success, and the ability of their goods to transcend space and time. Weavers of cotton and woolen textiles, potters, and most recently wood carvers who make alebrijes (painted wooden animals) produce goods that are bought [...] and sold on the international market and appear in museum collections world-wide. Nevertheless, there are crafts in Oaxaca that are not viable in the current market and that do not show up in international collections. In this paper, we examine one such craft: basket making in the community of San Juan Guelavia. We argue that the decline in the market for these goods reflects several changes: first, a decline in local use; second, a rise in the costs of production; and third, a lack of support by exporters and an inability to engage the export or tourist markets. In response, local producers have moved into wage labor (locally and through migration) to secure their incomes.

This place presents the greatest incidence and prevalence in the municipality. A descriptive and cross-sectional research was conducted including questioning, physical examination and electrocardiogram to the total of the sample chosen. Data were processed using percentage value and chi square when necessary. In the sample male sex prevailed over the female, and ages older than 56 in both groups. Ischemic heart disease without angina was the prevailing clinical manifestation; meanwhile alterations of the ST-segment were the most common electrocardiographic findings. Smoking, sedentary life and hypertension were the most frequent risk factors in the series, increasing with age and all of them prevailed in the group suffering from ischemic heart disease significantly. A direct relationship between risk factors associated and ischemic heart disease was found.

De igual manera, se describen algunos momentos de su infancia, sus estudios -- desde el bachillerato hasta su matrícula en la Facultad de Medicina y Cirugía -- y su labor como médico en diferentes localidades de la antigua provincia de Las Villas, con la puntualización de que debe ser considerado como el primer médico cubano que ejerció la medicina rural. Asimismo, se comenta el alzamiento desde Vega Alta y su meritoria labor en la lucha independentista, que le confirió en solo 14 meses el grado de general de brigada, para ser en esos momentos el brigadier más joven del Ejército Libertador. Finalmente, los autores analizaron diferentes versiones de su caída en combate el 30 de julio de 1895 Abstract in english Juan Bruno Zayas Alfonso was a brilliant military boss and an excellent doctor, who was an example of how to combine both tasks and became one of the most important personalities in the Cuban Independence War. This work compiles, historiographically and documentarily, important aspects of his life, [...] his family origins are pointed out, constituted by merchants and aristocrats on the part of the father, and sacarocrats and shareholders railwaymen on the part of the mother; and the evolution of a member of this family to revolutionary combatant's radical position conformed a social fact of great interest in the Cuban historiography. In a same way, some moments of his childhood are described, his studies -- from the high school to his registration in the Medicine and Surgery Faculty -- and his work as doctor in different towns of the old county of Las Villas, pointing out that he should be considered as the first Cuban doctor who exercised the rural medicine. Also, the raising from Vega Alta is commented and his meritorious work in the independentist fight, which conferred him in only 14 months the grade of general of brigade, to become in those moments the youngest brigadier in the Liberator Army.

Cedar Hills Field, San Juan County, New Mexico: a multi-well coal degasification project, San Juan Basin, New Mexico-a case study  

Energy Technology Data Exchange (ETDEWEB)

Amoco Production Company is operating a multi-well coal degasification site, Cedar Hills field, in San Juan County, New Mexico. Data presented here have been made available by Amoco at public hearings before the New Mexico Oil and Gas Commission. The Cedar Hills field produces from the lowermost coal bed in the Cretaceous, Fruitland Formation, stratigraphically positioned above the Pictured Cliffs Sandstone. The coal bed reservoir is 18-20 ft (5-6 m) thick at a depth of 2800 ft (853 m). The first well in this field was the Amoco 1 Cahn, completed in 1977 with an initial production of 200-300 MCFGD and 200-300 BWPD. These rates increased to 1.5 MMCFGD and 80 BWPD by January 1984. This well's production history exhibits a negative decline (incline) curve. Gas analyses, water analyses, and reservoir pressure data strongly indicate that the 1 Cahn well is producing from the Fruitland coal bed rather than the Fruitland sandstones or underlying Pictured Cliffs Sandstone.

Modern Monarchs and Democracy: Thailand’s Bhumibol Adulyadej and Juan Carlos of Spain  

Directory of Open Access Journals (Sweden)

Full Text Available The history of democracy is typically a history of struggle against monarchs and other such autocrats. The elevation of one person over others by virtue of blood and birth has come to be seen as anachronistic; yet some monarchies have managed to survive to this day. This paper analyses two examples of the uneasy coalition between popular sovereignty and royal leadership that is constitutional monarchy. Whereas Juan Carlos of Spain has been described as having steered Spain away from dictatorship, Bhumibol of Thailand has come under scrutiny for allegedly lacking a principled approach to democracy. I argue that structural as much as personal factors influenced the ways in which the two monarchies were legitimised – one by positively responding to the modern aspirations of the king’s subjects, giving him a “forward legitimacy,” the other by revitalising the king’s traditional charisma and opting for “backward legitimacy.”

Structurally controlled and aligned tight gas reservoir compartmentalization in the San Juan and Piceance Basins  

Energy Technology Data Exchange (ETDEWEB)

Recurrent basement faulting is the primary controlling mechanism for aligning and compartmentalizing upper Cretaceous aged tight gas reservoirs of the San Juan and Piceance Basins. Northwest trending structural lineaments that formed in conjunction with the Uncompahgre Highlands have profoundly influenced sedimentation trends and created boundaries for gas migration; sealing and compartmentalizing sedimentary packages in both basins. Fractures which formed over the structural lineaments provide permeability pathways which allowing gas recovery from otherwise tight gas reservoirs. Structural alignments and associated reservoir compartments have been accurately targeted by integrating advanced remote sensing imagery, high resolution aeromagnetics, seismic interpretation, stratigraphic mapping and dynamic structural modelling. This unifying methodology is a powerful tool for exploration geologists and is also a systematic approach to tight gas resource assessment in frontier basins.

Sustainable development and culture - Some reflections for their search in the Alto San Juan  

International Nuclear Information System (INIS)

The economic processes in the upstream San Juan River are determined by decisions taken in cultural frames in which the traditional groups and peasants build in hybrid forms of existence according with their own history and the availability of resources in the territory. In this way, they alternate different production systems that introduce them in different social and economic groups: local, zonal, regional, national and trans national; each one with a specific rationality, impacting in a particular way, in agreement with the system of dominant production over the environment. The features of the society and culture that impact the economic decision making can be revealed and strengthened in a coherent strategy that respects the regional and group specificities and that looks for the sustainable development of the region

Sus medidas son 77,5 cm de alto, 38 cm de ancho y 38,5 cm de fondo. Presenta elegancia señorial, carácter y vitalidad en su cabeza. Aparece ante nuestros ojos con los mismos ademanes y la misma figura rígida y envarada que los adultos. La actitud recogida junto con su sencilla vestimenta acentúan el intimismo religioso del orante. Se consideró que era interesante encontrar otros ejemplos de este tipo de escultura funeraria infantil en madera, material poco usado en este género debido a su propia naturaleza.

Análisis de la dinámica del Humedal Juan Amarillo (Colombia y su sostenibilidad  

Directory of Open Access Journals (Sweden)

Full Text Available La recuperación y mantenimiento del humedal Juan Amarillo requiere de un sistema de soporte, subsidiado
y respaldado por el sistema económico del cual el hombre hace parte. Si bien esto implica una inversión, está plenamente justificada por las ganancias que se reciben a cambio, tal como se demuestra con el estudio de los principales flujos de energía y el contenido emergético asociado a estos flujos. Adicionalmente, constituye en primer lugar en un deber del hombre sustituir lo que en cierto momento deterioró, y en segundo lugar es obligación de la administración distrital en proporcionar ambientes sanos para la comunidad. El hombre es ahora el principal actor que regula las relaciones energéticas de los componentes del sistema, es decir, los flujos energéticos que determinan la sostenibilidad, y consecuentemente, explican el comportamiento del sistema y la naturaleza de sus fluctuaciones; por lo tanto, este agente artificial es el factor determinante para su funcionamiento.

Analysis of The Surface Radiative Budget Using ATLAS Data for San Juan, Puerto Rico  

Science.gov (United States)

The additional beating of the air over the city is the result of the replacement of naturally vegetated surfaces with those composed of asphalt, concrete, rooftops and other man-made materials. The temperatures of these artificial surfaces can be 20 to 40 C higher than vegetated surfaces. This produces a dome of elevated air temperatures 5 to 8 C greater over the city, compared to the air temperatures over adjacent rural areas. Urban landscapes are a complex mixture of vegetated and nonvegetated surfaces. It is difficult to take enough temperature measurements over a large city area to characterize the complexity of urban radiant surface temperature variability. The NASA Airborne Thermal and Land Applications Sensor (ATLAS) operates in the visual and IR bands was used in February 2004 to collect data from San Juan, Puerto Rico with the main objective of investigating the Urban Heat Island (UHI) in tropical cities.

Antidiatom activity of marine bacteria associated with sponges from San Juan Island, Washington.  

Science.gov (United States)

Crude extracts of 52 marine bacteria associated with sponges, which were collected from the sea near San Juan Island, Washington, USA, were screened using diatom attachment assays against Amphora sp., Nitzschia closterium, Sellaphora sp. and Stauroneis sp. to investigate their antidiatom activities. Among these samples, five expressed strong anti-adhesion effects on all four tested diatoms. There was no negative effect observed from those five active samples on the growth of Amphora sp. Those five active samples were prepared from respective isolates, which all belonged to the genus Bacillus based on 16S rRNA gene sequencing analysis. The results of present study indicate that Bacillus may play important roles for sponges' chemical defence against biofouling of diatoms and that the metabolites of Bacillus may be a potential source of natural antifouling compounds.

Los datos registrados de UNSJ son ampliamente utilizados en aplicacion [...] es catastrales, y sirven como base para la definición de los marcos de referencia geodésicos nacional y regional. Como una componente fundamental de la infraestructura geodésica, resulta conveniente un eficiente control de calidad de los datos crudos y el monitoreo de la estabilidad de una estación GPS de referencia. En este trabajo se presentan los resultados del control de calidad de las observaciones UNSJ luego de dos anos de operación. Para contro l ar y caracterizar el desempeno del receptor GPS y además el medio ambiente de la estación, se eligieron cuatro índices. Ellos son el número de observaciones, multicamino en L1, multicamino en L2 y ocurrencia de saltos de ciclos. También, se evaluó la estabilidad de largo término de la estación UNSJ a través del análisis de las series temporales de las coordenadas semanales provistas por los centros de cálculo SIRGAS (Sistema de Referencia Geocéntrico para las Américas). Completa este estudio el análisis de las coordenadas calculadas por distintos servicios de procesamiento disponibles en Internet. Nuestros resultados indican que durante el período analizado, el funcionamiento de la estación UNSJ fue satisfactorio, produciendo índices de calidad que son aceptables para estándares internacionales. Abstract in english As a part of the Argentine continuously operating reference station network, a GPS (Global Positioning System) station named UNSJ (Universidad Nacional de San Juan) was established in San Juan city on 6th March 2007. The recorded data of UNSJ are widely applied to cadastral surveys and serve as the [...] basis for defining national and regional geodetic reference frames. As a key component of the geodetic infrastructure, an efficient quality control of raw data and stability monitoring of a GPS reference station is highly convenient. In this study, results of quality control of the UNSJ observations after two year of operation are reported. In order to check and characterize the receiver performance and the station environment, four indices were chosen. They are the number of observations, multipath on L1, multipath on L2 and cycle slips occurrence. Also, the long term stability of UNSJ station was evaluated through the analysis of weekly coordinate time series provided by the SIRGAS (Geocentric Reference System for the Americas) calculus centers. The analysis of the coordinates derived from different online processing services completes this study. The results indicate that during the analyzed period, the functioning of the station UNSJ was satisfactory, producing qualit indexes that are acceptable to international standards.

Vexierklänge. Anmerkungen zu einem Tiento de falsas von Juan Cabanilles  

Directory of Open Access Journals (Sweden)

Full Text Available The 5th tiento de falsas of Juan Bautista Cabanilles is off the beaten track of his further compositions with this designation. Besides the typical dissonances and unusual progressions in tientos de falsas, this piece for organ surprises with an intricate polyphonic setting. Nearly two thirds of the whole piece can be reduced to a minimum of motivic material, that is presented in continually new facets by canonic voice-leading, sequences and inversion. Yet the rhythmic and melodic structure of this piece of an altogether traditional style is not touched. The effect upon the listener, describable as thrilling or charming - at the same time vexing by the monotony and fascinating by the subtle harmonic graduation of the sounds - proves this tiento as a jewel of a very late manierism.

[de] Das fünfte Tiento de falsas von Juan Bautista Cabanilles fällt aus dem Rahmen seiner übrigen Kompositionen mit dieser Titelangabe. Neben den für die Tientos de falsas typischen Dissonanzen und ungewöhnlichen Fortschreitungen überrascht dieses Orgelstück mit einem intrikaten polyphonen Satz. Fast zwei Drittel des gesamten Stücks lassen sich auf ein Minimum an motivischem Material zurückführen, das durch kanonische Stimmführung, Sequenzierung und Umkehrung in immer neuen harmonischen Facetten gezeigt wird, während sich die rhythmische und die grobmelodische Struktur nicht verändert. Die Wirkung auf den Hörer, die ais durch die Monotonie quälender, jedoch durch die feinfarbliche harmonische Abstufung der Klänge gleichzeitig faszinierender Reiz beschrieben werden kann, weist in Verbindung mit der sehr traditionellen Satztechnik dieses Tiento ais ein Kabinettstiick des sehr spaten Manierismus aus.

Is the Juan Fernandez Ridge (nazca Plate) a Deep-Mantle Hot SPOT Trail?  

Science.gov (United States)

The Juan Fernández Ridge on the oceanic Nazca plate is thought to be a classic hot spot trail because of the apparent westward rejuvenation of the eruptive ages. Geochronological data is still scarce to prove this is the case, and other hypothesis should be taken into account. There are a few constrains, like the ca. 9 Ma Ar-Ar age of the O'Higgins seamount (115 km from the Chile-Perú trench), published K-Ar ages of ca. 3-4 Ma in Robinson Crusoe island (580 km from the trench) and ca. 1 Ma in Alejandro Selkirk (180 km further west). New reconnaissance K-Ar ages in Robinson Crusoe yield ca. 1-3 Ma, which partially overlap with the age of Alejandro Selkirk, breaking the expected age progression given that the Nazca plate moves eastwards at ca. 6-8 cm/yr. New geological mapping also shows a sharp unconformity between the older, strongly altered sequences and more recent, post-erosional volcanic piles, where only the vent facies have disappeared. A fixed deep-mantle plume origin for Pacific hot spots has been widely debated and concurrent phenomena arose as a possible explanation for non-linear age progressions and/or long-lived volcanic activity. In fact, intraplate regional tectonics, plume displacement, and mantle heterogeneities could be the main factor of the ridge architecture or the mask for a first-order linear trend. An ongoing mapping and dating effort is aimed to understand the evolution of the Juan Fernández Ridge, testing the main hypothesis. Fondecyt grant 110966 is acknowledged for financial support.

Crustal structure of the Central Precordillera of San Juan, Argentina (31°S) using teleseismic receiver functions  

Science.gov (United States)

The subduction of the Nazca plate under the South American plate around 31°S is characterized by flat slab geometry. The (Chilean) Pampean flat slab of Argentina associated with the subduction of the Juan Fernandez ridge lies in a region of a series of foreland uplifts corresponding to the thin-skinned Precordillera and basement cored Sierras Pampeanas ranges. The SIEMBRA project deployed 40 broadband stations in 2008-2009 in both the Precordillera and the Sierras Pampeanas with the aim to foster the understanding of the entire central Andean flat slab region. One of the SIEMBRA station (DOCA) located on the western flank of Sierra de la Invernada in the Central Precordillera appears particularly appropriate to study the crustal structure and eventually detect discontinuities related to terranes establishment. We thus performed a receiver function analysis using teleseismic data recorded at the DOCA station during the SIEMBRA project and from October 2011 to June 2012 using a broadband UNSJ (National University of San Juan) seismic station with the purpose to obtain crustal images with details of the intracrustal structure consistent with a mechanism that could explains both the observed earthquake depths and the uplift pattern in the Central Precordillera. Our results show that the Moho beneath the Precordillera lies at a depth of about 66 km. The Moho signal appears diminished and behaves irregularly as a function of azimuthal orientations. Although this observation could be the result of an irregular geometry it also correlates with the hypothesis of partial eclogitisation in the lower crust. Two mid-crustal discontinuities have also been revealed. The shallower one could correspond to a décollement level between the Precordilleran strata and the Cuyania basement at 21 km depth. The deeper one which the presence has been matched with a sharp decrease of the crustal seismic activity drove us to the hypothesis of a major change in crustal composition at 36 km. Finally the flat portion of the subducted slab has been imaged lying at about 100 km depth.

Historia de un consenso: Un recorrido por las miradas historiográficas sobre Juan Álvarez / History of a consensus: A journey through the historiographical perspective of Juan Álvarez  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish Aún el más breve recorrido por las opiniones de los historiadores contemporáneos sobre la obra de Juan Álvarez nos muestra, rápida y claramente, un balance extremadamente positivo de la misma. Autores de las más variadas orientaciones historiográficas, políticas e ideológicas (ya sean de la Academia [...] , renovadores annalistas, revisionistas, marxistas) coinciden en resaltar a Álvarez como uno de los mejores representantes de los estudios históricos argentinos, en particular de la historiografía económica argentina. Pero este extenso consenso encierra también una paradoja, o más evidentemente la sospecha, que tan disímiles orientaciones difícilmente puedan estar hablando del mismo Álvarez. Partiendo entonces de ese consenso, en este artículo pretendo adentrarme, en primer lugar, en esas valoraciones de la obra de Álvarez, en un recorrido que parte desde sus mismos contemporáneos hasta la historiografía actual, al tiempo que se intenta ir bosquejando un panorama que también recorra un arco extenso de las orientaciones historiográficas argentinas. En segundo término, pretendo indagar sobre qué aspectos de la obra de Álvarez se construyen tales valoraciones (particularmente sobre el rol fundante de la historiografía económica, pero también sobre el de un enfoque regional de la historia argentina, el de promotor germinal de una historia social, o el de la necesaria y explícita articulación de sus indagaciones históricas con las preocupaciones del presente, etc.) y cómo éstos son resignificados tanto en relación a las orientaciones más generales de las tradiciones historiográficas, como a las coyunturas en las que fueron formuladas. En definitiva, lo que se quiere marcar es como las miradas sobre Álvarez construyen una especie de calidoscopio en el cual las múltiples interpretaciones toman aspectos de la obra, efectivamente existentes la mayor parte de ellos, que dan como resultado ese consenso del que hablábamos; pero que también encierran toda una serie de disputas del campo historiográfico desde su misma constitución al presente; campo al que Álvarez se integró no sin dificultad, precisamente por esa matriz de orientaciones historiográficas que tan buen concepto generara posteriormente en el arco complejo de la historiografía argentina. Abstract in english Even the shortest review of the contemporary historiographers' opinions about Juan Alvarez' works shows in a clear and rapid way an extremely positive balance. Authors coming from the most varied historiographic, political and ideological orientations (either those from the Academy, renovators, anna [...] lists, revisionists, marxists) agree in pointing out Alvarez as one of the best representatives of the Argentine historiographic studies, in particular of the Argentine economic historiography. But this wide consensus also includes a paradox, or more evidently, a suspicion, that such dissimilar orientations could hardly be referring to the same Alvarez. With this consensus as a starting point, in this article we intend to go deeply, in the first place, into those valuations of Alvarez' works, starting with his own contemporaries and getting to the current historiography, at the same time trying to outline an outlook which also covers a broad variety of Argentine historiographic orientations. In the second place, I intend to inquire onto which aspects of Alvarez' works these valuations are built (particularly in relation to the founding role of economic history, but also to the regional approach to Argentine history, the promoter of a social history, or to the necessary and explicit articulation of his historical inquiries with the concerns about the present time, etc.), and how they are resignified both in relation to the more general orientations in the historiographic traditions as well as the junctures in which the were formulated. In short, we are trying to point out how the points of view about Alvarez comprise a kind of kaleidoscope in wh

Monitoring of the artificial reef fish assemblages of golfe juan marine protected area (France, North-Western Mediterranean)  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Artificial reefs were deployed within the Golfe-Juan marine protected area (Alpes-Maritimes coast, France, Northwestern Mediterranean) created in 1981. This no-take area is fully protected since its establishment, except in 2004 when some anthropic activities were, exceptionally, authorized. Moreover, no park rangers to prevent poaching since 2002 occur. In order to carry out a long term monitoring of the artificial reef fish assemblages, underwater visual censuses (UVC) were carried out in 1...

Determining the Habitat Preference of Sand Lance (Ammodytes hexapterus) Using Multibeam Bathymetry in the San Juan Islands, Washington  

Science.gov (United States)

Ammodytes hexapterus (Pacific Sand Lance or PSL) is an important forage fish supporting many marine populations, ranging from salmon, harbor seals, and whales. Previous studies have shown PSL to be highly substrate specific (Robards et al., 1999). Sand lance spend time buried in the substrate and come out into the water column to feed. This is due to the lack of swim bladders. If the sand particles are too fine their gills can be clogged (Wright et al., 2000). Little is known about the species sub-tidal habitat and new information regarding habitat preferences in deep water would be beneficial in determining their distribution and abundance. Preliminary examination undertaken in this investigation was limited to three sand wave fields: one, the central San Juan Channel (a known PSL sub-tidal habitat), and two previously un-sampled fields west of Sucia Island and southwest of Lopez Island in the waters surrounding the San Juan Islands, Washington. Multibeam bathymetric data, subsea video, and sediment analysis show that PSL have occupied the San Juan Channel, which is composed of well-sorted medium grained (~500 ?m size) siliciclastic sand. Several sediment samples from in and around the fields were collected and analyzed to determine a grain size distribution of the sediments. The two un-sampled fields examined have an average grain size higher and lower respectively than the San Juan Channel field. The expected results of this study are to determine whether or not the two newly sampled sediment wave fields are potential sub-tidal habitats of PSL.

A continuación, también de manera general, se muestran las grandes líneas del pensamiento de san Juan de la Cruz en torno a la sustancia, específicamente en el comentario a la primera canción de su última obra Llama de Amor Viva, que en muchos aspectos representa una cumbre de la mística occidental. Finalmente, desde estos dos pasos, se pretende dar pistas para la cuestión de fondo: ¿qué aporte ofrece esta obra mística de san Juan de la Cruz a la cuestión del ser?In this article the author attempts to present in a synthetic manner, in the first place, an exposition on the theological esthetics represented in the style of St. John of the Cross, which Hans Urs von Balthasar discovered in his work, The Glory of the Lord. Following this, the author shows, also in a general way, the major lines of thought of St. John of the Cross regarding substance, especially in his commentary on the first song in his last work, The Living Flame of Love, which in many aspects represents the summit of Western mysticism. Finally, from these two steps, the author attempts to give some insights into the question at the heart of the matter: What contributions does this mystical work of St. John of the Cross offer to the question of being?

Rapports de parenté et de production à San Juan, haute vallée du Chancay, Pérou  

Directory of Open Access Journals (Sweden)

Full Text Available Les relations de parenté dans l'organisation des communautés andines sont particulièrement importantes, ce qui est aussi le cas à San Juan. L'utilisation et la distribution de l'eau en fonction de 'turnos' se font selon diverses combinaisons basées sur les relations de parenté. Il est vraisemblable que l'organisation des tours à l'intérieur du village et par quartiers se fasse également en fonction de la distribution des familles. L'élevage est aussi lié à ces relations de parenté, en particulier l'élaboration des fromages: les femmes ont ici une place prépondérante, tout comme pour l'irrigation. Ainsi les relations de parenté constituent un capital précieux, mais seulement dans le cas d'une société traditionnelle fonctionnant par prestations mutuelles. Or, on assiste actuellement à un développement du travail libre favorisé par les possibilités d'accumulation individuelle d'argent (vente de fruits, des produits de l'élevage. La division sexuelle du travail est envisagée en fin d'article. Las relaciones de parentesco en la organización de las comunidades andinas son particularmente importantes, lo cual también es el caso de San Juan. La utilización y distribución del agua, en función de 'turnos' se efectúa de acuerdo a diversas combinaciones basadas en las relaciones de parentesco. Es verosímil que la organización de turnos para el agua en el interior del pueblo y por barrios se efectúe igualmente en función de la distribución de las familias. La cría de ganado también estaba ligada a estas relaciones de parentesco, sobre todo la elaboración de quesos: en esto las mujeres tienen un lugar preponderante, así como para la irrigación. Así pues las relaciones de parentesco constituyen un capital precioso, pero tan solo en el caso de una sociedad tradicional que funcione por prestaciones mutuas. Ahora bien, actualmente se asiste a un desarrollo de trabajo libre favorecido por las posibilidades de acumulación individual de dinero (por venta de frutas, o productos de la crianza de ganado. La división sexual del trabajo es observada atentamente al final del artículo. Relations of relationship in the organization of andean communities are particularly important and this is also the case of San Juan. Utilization and distribution of water in function of the turnos are also related to different combinations based upon relations of relationship. It is probable that the organization of water turns in the village itself and by parts is also related to family distribution. Cattle raising is also tied to these relations of relationship, principally for the elaboration of cheese: there women play an important part as for the irrigation. So, relations of relationship settle a precious capital, but only in the case of a traditional society functioning by mutual prestatations. Now, we will see today free work development helped by possibilities of individual accumulation of money (fruit and cattle raising product selling. At the end, we will consider sexual work differentiations.

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish En el flanco oriental de la sierra de La Invernada, Precordillera Central de San Juan, aflora una sucesión marino-clástica del Ordovícico Superior-Silúrico, asignada al Grupo Tucunuco, integrada por las formaciones La Chilca, su equivalente lateral Los Bretes (Hirnantiano?-Wenlockiano temprano), y l [...] a Formación Los Espejos (Wenlockiano medio-Ludowiano), con espesores variables entre 150 m y 220 m. Esta sucesión yace en discordancia erosiva (paraconcordancia), sobre calizas de la Formación San Juan (Ordovícico temprano), y es cubierta en paraconcordancia por depósitos devónicos de la Formación Punta Negra. En el área de Gualilán, la Formación La Chilca está representada por una sucesión de pelitas y areniscas estrato-granocreciente, que hacia el sur cambian a facies de pelitas bioturbadas formalmente denominadas en este trabajo Formación Los Bretes (nom.nov) (="Facies Pachaco de la Formación Tambolar"), cuyo estrato-tipo se propone en el cerro Blanco de Pachaco. La Formación Los Espejos sobreyace en paraconcordancia a la Formación La Chilca, presenta arreglo estrato-granocreciente, con pelitas transgresivas a la base, vaques, acumulaciones bioclásticas y estructuras de deformación sinsedimentaria en la parte superior. La Formación Los Espejos no aflora en Pachaco, pero sus depósitos se encuentran resedimentados en olistostromas del Devónico. Los depósitos silúricos del área de estudio muestran posición relativa distal, respecto a sus equivalentes de la Precordillera Central. El cambio de facies de la Formación La Chilca y ausencia de la Formación Los Espejos, se interpreta como resultado del basculamiento de la cuenca silúrica hacia el norte debido al control estructural del Alto del Tambolar. Abstract in english A Silurian siliciclastic succession, assigned to the Tucunuco Group, composed of the La Chilca/Los Bretes (Hirnantian? to early Wenlock), and the Los Espejos (middle Wenlock to Ludlow) formations, is described on the eastern flanck of the sierra de La Invernada, at the Central Precordillera. In the [...] Gualilán area, the La Chilca Formation is composed by of silt and sand thickening and coarsening upward sequence (shallowing), exhibiting a facies change towards the south to bioturbated shale named "Facies Pachaco of the Tambolar Formation", which formally is here redefined as Los Bretes Formation, its type section is located at the cerro Blanco de Pachaco. The Los Espejos Formation shows a marked southward onlap toward south, but it is not exposed in the San Juan River area; there, its deposits appear reworked into the Los Sombreros Formation. The Punta Negra Formation paraconformably overlies the Los Espejos Formation (Gualilán area), and to the Los Bretes Formation (Pachaco area) and, in turn, it erosively underlies the Los Sombreros Formation, which age is assigned to the Devonian post-Punta Negra Formation on the basis of its stratigraphic relationship, and lithological and paleobiological features. The Silurian succession shows a relative distal position in comparison with its correlatives from the Central Precordillera. The facies change of the La Chilca Formation and the southward onlap of the Los Espejos Formation, are interpreted as a result of northward tilting of the Silurian basin.

Entretelones de una "estética operatoria" Luis Juan Guerrero y Walter Benjamin  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish En este artículo se ensaya una aproximación a la labor estético-filosófica del argentino Luis Juan Guerrero (1899-1957), a través de un cotejo de su temprana y productiva recepción de algunos aspectos centrales de la obra de Walter Benjamin. Se intenta mostrar que esta clave de lectura permite un ac [...] ceso privilegiado a la labor de Guerrero, a la vez que ayuda a construir una imagen más compleja y matizada de la generación intelectual "antipositivista" a la que perteneció. La olvidada obra de Guerrero se compone principalmente de trabajos sobre ética, psicología y estética. Acotaremos nuestra atención a su principal trabajo, y acaso la obra sobre estética más ambiciosa jamás escrita en nuestro país: Estética Operatoria en sus Tres Direcciones. Se muestra en el artículo que la summa estética de Guerrero, si bien expresa con toda claridad las preocupaciones centrales de una generación intelectual marcada por la cultura alemana de entreguerras y por la problemática de la "crisis de la cultura", inscribe, a su vez, una anomalía -benjaminiana-, una inflexión político-materialista, que pone en cuestión la idea frecuente de que la "crisis de la cultura" una y otra vez diagnosticada en aquella época mostró siempre alternativas "espiritualistas" de resolución. Abstract in english This essay deals with the aesthetic-philosophical work of the Argentinean Luis Juan Guerrero (1899-1957), through a consideration of its early and fruitful reception of some central aspects of Walter Benjamin's work. It is shown that this perspective allows a privileged access to Guerrero's work, at [...] the same time that it makes more complex the image of the "anti-positivistic" intellectual generation in Argentina. Guerrero's forgotten work includes principally contributions on ethics, psychology and aesthetics. This essay will pay attention only to his most important work, maybe the most ambitious aesthetic work ever written in Argentina: Operatory Aesthetics in its Three Directions. This aesthetic summa, although it expresses the typical features of an intellectual generation marked by German interwar culture and the concerns on the "culture crisis", it also inscribes a benjaminian anomaly, a political-materialistic inflection, that questions the frequent opinion that the "culture crisis" in those years diagnosed always showed "spiritualist" answers.

Foi possível reconhecer uma zona confinada de baixa velocidade de fase, que indica porosidade e quantidade de água mais elevadas.

Abstract in english This work presents some geophysical results obtained at Mesón San Juan located in the Central Andes (6,012 m, 33°30' Sand 69°49' W), on the border of Argentina and Chile. The permafrost plateau (4,400 m) situated at the loot of the glacier is limited by recent moraines produced by cryogenic phenom [...] ena. The geophysical results revealed lateral differences in the dielectric characteristics of the subsurface due to varying water contents, allowing a zoning of the permafrost structure. We have compared the electrical permittivities in a semi-quantitative way through a trial-and-error migration procedure, taking advantage of the clutter present in the permafrost as seen in the fixed-offset data. In this way we were able to recognize a confined zone of relatively low phase velocity indicating higher porosity and water content. We interpret that zone as degraded permafrost , probably a result of the impact of global warming on the Andean cryolithozone. That zone is likely a discharge channel linking a suprapermafrost to a subpermafrost aquifer, part of a laterally discontinuous near surface system not mapped in this work.

Analysis of Upper Air, Ground and Remote Sensing Data for the Atlas Field Campaign in San Juan, Puerto Rico  

Science.gov (United States)

The general climate of the island of Puerto Rico is dominated by the easterly trade winds from the Atlantic Ocean, and during synoptically calm days by the topographic and local land surface characteristics [1]. The urban canopy of the metropolitan area of San Juan, capital city of the Island, may introduce a new microclimate that changes the characteristics of the low atmosphere and interacts with the other microclimates already present in the island. The primitive land cover and land use (LCLU) of the metropolitan area of San Juan was composed by broadleaf trees, moist soils, and very dense vegetation in general. The urban LCLU changes the balance for the mass, momentum and energy between the bottom boundary and the lower atmosphere, creating different climate conditions over urban and rural regions. Some of these differences are low relative humidity and high temperatures observed in urban areas when compared to rural areas. These in turn produces a convective circulation over the urban areas, a phenomenon compared to the sea and land breezes, commonly known as heat islands (UHI). Factors that contribute to the formation of the UHI are anthropogenic heat sources, aerosols from pollutants, fast water canalization due to the presence of buildings and streets, among others. The comparison between urban and rural climates is the most common approach to analyze the UHI. These contrasts are larger in clear and calm conditions and tend to disappear in cloudy and windy weather. The UHI was recognized in the early 1950 s as closed isotherms that separates the city from the general temperature field [2]. The impact of the urban LCLU in San Juan, Puerto Rico, was quantified calculating the difference between historical data sets for the air temperature over an identified urban area and a rural area dT(U-R). The analysis of the climatological data revealed that a UHI exists in the metropolitan area of San Juan, Puerto Rico. The data reveals a permanent urban heat island effect present in the SJMA during the year, which is increasing at a rate of 0.41oC/decade. These findings encouraged the planning and execution of an intense field campaign in February 2004 referred as the ATLAS San Juan mission. The focus of the remaining of this report is the analysis of the data for this field campaign.

Sedimentary history and economic geology of San Juan Basin, New Mexico and Colorado  

International Nuclear Information System (INIS)

The San Juan Basin contains up to 15,000 ft of sedimentary rocks ranging in age from Cambrian to Recent. The earliest development of the area as a sedimentary basin or trough apparently took place in Pennsylvanian time, and the basin was maintained, with changing rates of subsidence and filling, through the remainder of geologic time. During the Early Paleozoic, sedimentation was dominated by marine transgressions across the northwestern flank of the regional Transcontinental Arch. The Late Paleozoic history was strongly influenced by tectonism related to development of the Ancestral Rocky Mountains Uplifts and associated downwarping. The Early Mesozoic is characterized by fluvial and eolian environments, interrupted periodically by thin marine transgressive deposits of nearshore redbeds. The final Mesozoic event was the widespread Late Cretaceous marine transgression which deposited a thick cyclic sequence of marine gray shale and sandstone, with interbedded coal. Late Tertiary regional uplift and resulting volcanism were accompanied by a regional dissection of the area by stream systems that evolved into the present drainage pattern of superposed streams. The sedimentary history is directly related to the occurrence of economic deposits in the basin. Major reserves of petroleum and gas are in Cretaceous and Pennsylvanian rocks, coal in Cretaceous, and uranium in Jurassic and Cretaceous. Abstract only

Eating in a Home for Children. Food Resistance in the Residence Juan de Lanuza  

Directory of Open Access Journals (Sweden)

Full Text Available The basic needs of the children of the Residence Juan de Lanuza (Zaragoza, Spain are covered by the daily amount of food they are provided with at meals. However, the tasks of the professionals who work in this Home are not restricted to feeding. One of the educational goals is to teach children socially adapted food habits, which are considered essential for the young persons’ “culturisation”. Food socialization has its roots in the ideology of the educating staff. The disciplinary system is based on the containment of deviations from normative food habits. The harshest punishment is inflicted when the child refuses to eat. The aim of this paper is to show that the resistance to food offered by the children of this Home between 6 and 12 years of age, is not due to lack of appetite but is the expression of a specific demand. Through their behaviour the children make explicit their wish to belong to a certain age group, they assert their ethnic difference, they show whether they wish to relate or not to other children or the staff, they ask for the educator’s attention to their state of mind, etc.

[Social thinking in health in Latin America: revisiting Juan César García].  

Science.gov (United States)

The article reconstitutes the social thinking in health by Argentine physician and sociologist Juan César García (1932-1984), analyzing the main publications approaching his work and activities. The article situates his thinking in the two fields that marked his production: social medicine and the social sciences from the 1960s to the late 1980s. The article highlights his work with the Pan American Health Organization and his perspective of analyzing social medicine and the social sciences by relating them not only to the Latin American historical, social, economic, and political context, but also to historical materialism: linking medicine to the social structure; the influence of the social structure on the production and distribution of diseases; internal analysis of the production of medical services; and the relationship between training of health personnel and the medical field. As demonstrated, even today his work can be a reference for the discussion of such themes as medical education, health personnel training, the role of science and technology, the social sciences in medical education, and historical aspects of public health.

Hydrothermal fluid effects on sediment column in Middle Valley, Juan de Fuca Ridge (northeast Pacific)  

Energy Technology Data Exchange (ETDEWEB)

Core PAR 85-34, located near a high heat flow area in Middle Valley, northern Juan de Fuca Ridge, contains carbonate nodules of various sizes (less than or equal to 1-5 cm in length). Sedimentological, geochemical, and isotopic results allow us to understand the origin of these concretions and the effects of hydrothermal activity from nearby sulfide vents on the sediment column. The mineralogy of the olive-gray surface sediment (0-15 cm) is identical to unaffected hemipelagic sediments in the region except for a concentration of barite crystals (up to 1 cm) at the water-sediment interface. In the clay, mud fraction, and bulk sediment, the FeO, S, Ba, Cu, Ni, Pb, Zn and As are more enriched than in normal hemipelagic sediment in the area due to hydrothermal activity. Petrographic and SEM analysis of the nodules reveal iron calcite and barite minerals in cracks and on the outside part of the nodules with mineralogical and textural variations downcore. Stable isotope curves of these nodules appear to demonstrate the effects of both bacterial sulfate reduction and microbiological methane generation, with consequent extreme /sup 13/C-depletion in the precipitated carbonate. The curves also demonstrate that the hydrothermal fluid entering the system may have caused the negative shift in oxygen isotopes downcore, although this effect may have been of cyclic or episodic nature.

This work is a preliminary diagnosis of the actual state of the high-montane water sources located in the Juan Cojo's and El Salado's basins of the NE side of the Aburra valley' both belong to the Girardota municipality (6 degrades 20.951' N, 75 celsius 27.199' W between 1900 and 2500 meter above sea level in the central montane chain. in order to achieve this work several samples were taken in august 10, 11, 17 and 19 of 2004. this preliminary study includes the physicochemical and microbiological evaluation of 30 sampling points. just one of the 30 sampling points exhibited absence of microbiological pollution due to fecal and total coliforms. this fact suggests bad practices in the final disposal of domestic and farming water residuals. in the other hand, the physicochemical and the ICA (water quality index) evaluation reveal that the sampled water sources exhibit typical characteristics of common low-montane ,non-polluted water sources. in other words, although pollution levels found in those water sources are not alarming, they do not exhibit the typical pollution levels found in natural high-montane waters, as they should, even we could find some sampling points with meso-eutrophic conditions

Stratigraphy, sedimentology and paleontology of lower Eocene San Jose formation, central San Juan basin, New Mexico  

Energy Technology Data Exchange (ETDEWEB)

The lower Eocene San Jose Formation in the central portion of the San Juan basin (Gobernador-Vigas Canyon area) consists of the Cuba Mesa, Regina, Llaves, and Tapicitos Members. Well log data indicate that, from its 100-m thickness, the Cuba Mesa Member thins toward the basin center and pinches out to the northeast by lat. 36{degree}40'N, long. 107{degree}19'W. The Regina Member has the most extensive outcrops in the central basin, and it decreases in sandstone/mud rock ratio to the north. The Llaves and Tapicitos Members occur only at the highest elevations, are thin due to erosion, and are not mappable as separate units. Well log data and 1,275 m of measured stratigraphic section in the Regina, Llaves, and Tapicitos Members indicate these strata are composed of approximately 35% medium to coarse-grained sandstone and 65% fine-grained sandstone and mud rock. Sedimentology and sediment-dispersal patterns indicate deposition by generally south-flowing streams that had sources to the northwest, northeast, and east. Low-sinuosity, sand-bedded, braided( ) streams shifted laterally across about 1 km-wide channel belts to produce sheet sandstones that are prominent throughout the San Jose Formation. Subtle levees separated channel environments from floodplain and local lacustrine areas. Avulsion relocated channels periodically to areas on the floodplain, resulting in the typically disconnected sheet sandstones within muddy overbank deposits of the Regina Member.

Profile of prospective bioengineering students at National University of San Juan  

International Nuclear Information System (INIS)

The low percentage of students (43 % of applicants) that passed the entrance exams for the bioengineering career at the National University of San Juan in 2007, plus the historical situation of desertion in first year (about 50%), motivated the application of a diagnostic test to prospective students of this career. The aim of this test was to obtain information about the competences acquired by students to solve problems in different contexts using basic mathematical tools, reading comprehension skills to understand texts, graphs and tables. Although this test was sat by the entire population of applicants of the current school year, only the results belonging to bioengineering students are the ones presented for the purpose of this work. However, students of other disciplines of the school of engineering also have similar problems. From the analysis of the answers to the different items, it can be observed that there are serious difficulties in the development of basic capacities to successfully take the courses of this career

Ingermina, de Juan José Nieto: antagonismo y alegoría en los orígenes de la novela caribeña.  

Directory of Open Access Journals (Sweden)

Full Text Available This paper analyzes a pioneering novel in the literary tradition of the Colombian Caribbean: Ingermina, published by Juan José Nieto during his exile to Jamaica in 1844, and practically forgotten for a century and a half, until it was reedited in 1998. Ingermina tells of the conquest of the Kingdom of Calamar and its conversion into the colonial Cartagena of the New Granada. The text revolves around the love between an Indian woman and a Spanish colonist. In contrast to other stories (such as the Mexican Malinche, Iracema in Brazil, etc., Nieto’s novel offers a notably diverse view of the indigenous population, which is divided between radical and moderate anti-colonialists. My article analyzes the subsumption made by Nieto, of a political antagonism under a moral antagonism. Firmly planted within the context of Colombia in the 19th century, I refer this subsumption to the limits of Nieto’s liberalism, one of the most radical of his time.

Metal sources of black smoker chimneys, Endeavour Segment, Juan de Fuca Ridge: Pb isotope constraints  

International Nuclear Information System (INIS)

Hydrothermal chimney sulfides, vent cap chimney samples, Fe-oxide and basalts from sediment-starving Juan de Fuca Ridge, in the Endeavour segment, exhibit a range of Pb isotope ratios (206Pb/204Pb = 18.658-18.769; 207Pb/204Pb = 15.457-15.566; 208Pb/204Pb = 37.810-38.276). The data array is not parallel to the northern hemisphere mantle reservoirs indicating a possible sediment component within the sulfides. By assuming that the potential end-member sediment component has a 207Pb/204Pb (15.70) similar to Middle Valley sediment, it is suggested the potential end-member sediment component may have 206Pb/204Pb = 18.90; 208Pb/204Pb = 38.82. Basalt-derived Pb for the Endeavour segment hydrothermal system involves about 50/50 leaching of E-MORB and T2-MORB. Detailed observations show the Mothra field derives more Pb from T2-MORB than the Main Endeavour field does. According to the binary mixing model, the results show little Pb (4+, CH4 and Br/Cl ratios in hydrothermal fluids are consistent with a sediment component within the segment. Reconciling the Pb isotope data with the chemistry data of hydrothermal fluids, it is suggested that the sediment component may be located in a lower temperature recharge zone where Pb could not be mobilized from the sediment.

Timescale of open-reservoir evolution beneath the south Cleft segment, Juan de Fuca ridge  

Science.gov (United States)

Lavas erupted at the southern end of the intermediate Juan de Fuca ridge (Cleft segment) are mostly cogenetic and their chemical diversity results from melt evolution in an open magma system. In the present study, we apply a theoretical model allowing the time evolution of this periodically recharged and tapped magma chamber to be estimated. In our mathematical procedure, the melt quantity supplied to the reservoir varies through time following a sinusoidal function. The rare earth element concentrations in the refilling melt were calculated on the basis of the REE distribution in lavas. This theoretical composition is akin to that previously estimated for a Mg#70 MORB from mineralogical and chemical data. Then, we approached the temporal evolution of the reservoir using a set of suitable parameters deduced from the geometry of the crust and magma system beneath the Cleft segment. Particularly, we considered two end-members scenarios for the melt repartition through the magma reservoir beneath the Cleft segment: the "gabbro glacier" model (crystal nucleation and growth occur within one single melt lens and crystals subside vertically and laterally) and the "sheeted sill" model (crystallization takes place within a network of connected sills located at various depths within the crust). We estimated that the magma chamber is refilled every thousand years and that the melt resides approximately one hundred years within the reservoir.

New additions to the introduced flora of the Juan Fernández Islands: origin, distribution, life history traits, and potential of invasion Nuevas adiciones a la flora introducida de las Islas Juan Fernández: origen, distribución, rasgos de historia de vida y potencial de invasión  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Oceanic islands, such as Juan Fernández in Chile, are the home for particular biotas that have evolved in isolation over a long period. The anthropogenic introduction of allochtonous plants is one of many problems for the conservation of endemic elements. In this paper, we present the new additions to the introduced flora of the Juan Fernández Islands, adding some comments about their life form, origin, morphological characteristics, ecology, distribution, abundance, and their potential of ...

Abstract in english The Cambro-Ordovician carbonate platform succession of the Precordillera Oriental of western Argentina is some 2000 m thick and consists of five formations, from base to top, La Laja, Zonda, La Flecha, La Silla and San Juan (Keller, 1999; Bordonaro, 2003). La Silla Formation (latest Cambrian-Early O [...] rdovician) was defined by Keller et al. (1994) from the lower part of the San Juan Formation. It reaches some 350 m in thickness and consists of a distinctive succession of dominantly light-coloured, poorly fossiliferous limestones. The upper part of La Silla Formation is extensively quarried because of the remarkable purity of the limestones. Based on a detailed study of the type section in the northern outcrop area near Jáchal and seven sections in the southern area near San Juan (Fig. 1a), we propose a formal stratigraphic subdivision of La Silla Formation into three members. These are, from base to top, the Río del Agua Member, Río Blanco Member and Río Salado Member (Fig. 1b), which are 85, 140 and 81 m in their respective type sections. This subdivision is based in the preferential occurrence of creamcoloured dolostones interbedded in the middle part of the formation, whereas the lower and upper members are essentially monotonous limestones. Keller (1999) erected an informal tripartite subdivision conforming to three putative, shallowing-upward sequences, with the boundaries recording abrupt changes in relative sealevel. We do not detect this pattern and our proposed members do not coincide with this subdivision. We recognize nine individual lithofacies types (Fig. 2a-f). These are for the most part similar to those determined by Keller (1999) and Cañas (1999), but we consider that they over-estimated the abundance of muddy facies in the form of lime mudstone, wackestone and packstone. Limestones in all three members are dominantly thick- and massively bedded peloidal grainstones exhibiting tabular and gently undulating bedding. In the lower and upper members there are subordinate ooidal grainstones, along with rare peloidal packstone, intraclastic rudstone, mudstone, microbial laminites

Juan Bautista Alberdi was a lawyer, writer, journalist and economist always concerned with the construction of the nationality of the region that would become Argentina in those early stages of capitalism's expansion that had England as its center of interest. Alberdi tried to understand his country from a liberal perspective, but with the local structures in mind. He defended, in the process, social and regional inclusion, a better power-sharing and a more equitable fiscal federalism for the region. He went far beyond the simple defense of international division of labor. If, at the beginning of his intellectual life, he presented himself as an optimistic thinker, with the course of events, particularly during the second half of the nineteenth century, he looked with distrust and pessimism at the liberalism's construction led by Buenos Aires.

Influence of the San Juan mountain geothermal anomaly and other tertiary igneous events of the coalbed methane potential in the Piceance, San Juan, and Raton basins, Colorado and New Mexico  

Energy Technology Data Exchange (ETDEWEB)

This paper presents a discussion of the development of gas resource in the subject basins and why the particular portions of those basins are gas-rich. It is suggested that the anomalously high geothermal gradients induced by the intrusion of the San Juan Mountain complex and aided locally by other Tertiary events is substantially responsible for the high-rank coals observed in these areas, and therefore is principally responsible for the anomalously high methane content and the high potential for coalbed methane production from these areas. 9 refs.

Application of seismic refraction tomography for tunnel design in Santa Clara Mountain, San Juan, Argentina  

Scientific Electronic Library Online (English)

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish Se llevó a cabo un estudio geofísico de tomografía sísmica por refracción (SRT) con ondas compresionales en la Sierra de Santa Clara, provincia de San Juan, República Argentina en julio de 2009. El propósito del estudio geofísico fue determinar las variaciones de velocidad de ondas P en el interior [...] del macizo rocoso con el fin de inferir el grado de fracturación y rigidez del mismo, y proyectar la construcción de un túnel vial de 290 m de longitud, que atravesará la montaña de forma casi perpendicular al eje de la misma, a 100 m de profundidad desde la cumbre. Varias dificultades se presentaron desde el punto de vista operativo, que tornaron altamente compleja la realización del trabajo de campo en circunstancias normales. En primer lugar las condiciones topográficas, con pendientes de 45° y profundidades de investigación de 100 m, que implicaba el uso de explosivos para generar ondas sísmicas que alcanzaran los sensores con suficiente relación señal-ruido para distinguirlas. Restricciones legales respecto al uso de explosivos, por una parte, y la potencia insuficiente en caso de uso de golpe de maza por otra, hicieron necesario el diseño y construcción de un cañón impulsado por gas en busca de generar la energía mínima (2 kJ) necesaria para la detección de las señales sísmicas. En segundo lugar, no fue posible la utilización de los métodos convencionales de interpretación que emplean modelos de capas, inoperable en este tipo de estructuras geológicas; por ello resultó imprescindible utilizar el método de tomografìa sísmica que hace uso del concepto de gradientes de velocidades, tanto laterales como en profundidad. Ello posibilitó mapear las variaciones de velocidad en subsuelo en forma de curvas de nivel. Abstract in english A geophysical survey involving seismic refraction tomography (SRT) for mapping 'P' waves was carried out in Sierra Santa Clara, San Juan Province, Argentina in July 2009. The purpose of the geophysical survey was to determine the degree of fracturing and the rigidity of the rock mass through which i [...] t is planned to build a 290 m long road tunnel traversing the mountain almost perpendicular to the axis thereof, at around 100 m depth from the summit. Several difficulties arose from the operational point of view which made it almost impossible to conduct fieldwork in normal circumstances. Firstly, the topography had almost 45° slopes and 100 m research depths which would have involved having had to use explosives to generate seismic waves reaching sensors which had sufficient signal-to-noise ratio for distinguishing them. Legal restrictions regarding the use of explosives on the one hand and insufficient power when using hammer blows on the other made it necessary to design and build a gas-powered gun to achieve the minimum energy (2 kJ) required for detecting seismic signals. Secondly, using conventional interpretation methods involving layered models was inoperable in such geological structures; seismic tomography methods were thus used which make use of the velocity gradient concept (both lateral and in-depth). This allowed mapping subsurface velocity variations in the form of velocity contour lines. The methodology used with the new seismic waves' source generator, as well as SRT application in this type of geological structure, demonstrated that satisfactory results could be obtained for this kind of geophysical study for geotechnical purposes.

El doctor Juan Santos Fernández Hernández y la Crónica Médico-Quirúrgica de la habana  

Directory of Open Access Journals (Sweden)

Full Text Available Durante el último tercio del período colonial, caracterizado por reiterados enfrentamientos políticos e inestables situaciones económicas, era casi imposible que algún médico criollo pudiera convertirse en un especialista de prestigio, dadas la carencia de escenarios donde demostrar la competencia adquirida y la falta de emolumentos que obligaban a la práctica de la medicina general. El doctor Juan Santos Fernández Hernández, además de superar ese escollo al ser el primer cubano en ejercer la Oftalmología y consolidarla como especialidad independiente, fue protagonista principal de un renacimiento científico en nuestro país. Uno de sus aportes más relevantes en este sentido fue la fundación de una revista que, con el título de Crónica Médico-Quirúrgica de La Habana, registró durante 66 años los trabajos de los más altos exponentes de la cultura médica nacional. Esta revista, ubicada en un lugar de preferencia en los anales de la bibliografía médica cubana de todas las épocas, atesora en sus páginas materiales de consulta obligada para los documentalistas consagrados a la labor histórico-bibliográfica y para los interesados en conocer todo lo que guarda relación con la evolución de las ciencias de la salud en la isla entre 1875 y 1940. En este artículo se trata de evitar que la inexorable acción del tiempo continúe absorbiendo y ocultando el valor de este baluarte de la documentación médica nacional, al consignar algunos rasgos importantes de la vida y la obra de su fundador y brindar detalles en relación con sus aspectos formales y de contenido.During the last third of the colonial period, characterized by repeated political confrontations and unstable economic situations, it was almost impossible that some Cuban physician could become a specialist of prestige, due to the shortage of settings where to show the competence acquired and the lack of fees that forced to the practice of general medicine. Dr. Juan Santos Fernández Hernández, besides overcoming that obstacle upon being the first Cuban to practice Ophthalmology and consolidate it as an independent specialty, was a major figure of a scientific revival in his country. One of his most relevant contributions in this sense was the foundation of a magazine that, under the title of Crónica Médico-Quirúrgica de La Habana, registered during 66 years the works of the highest representatives of the national medical culture. This magazine, established in a place of preference in the annals of Cuban medical bibliography of all times, amasses in its pages materials of obligatory reference for the specialists devoted to the historical- bibliographic work and for those interested in knowing all what is related to the evolution of the sciences of health in the island between 1875 and 1940. The present paper tries to prevent the inexorable action of time from keeping on absorbing and hiding the value of this remarkable exponent of national medical documentation, upon registering some important features of the life and work of its founder and giving details with respect to its formal and content aspects.

Candidiasis sistémica: experiencia en el Hospital San Juan de Dios 1996-1998  

Scientific Electronic Library Online (English)

Full Text Available SciELO Costa Rica | Language: Spanish Abstract in spanish La sobrevida de los pacientes con enfermedades crónicas así como de aquellos expuestos a terapias médicas y quirúrgicas agresivas ha aumentado. entre otras cosas, gracias al empleo de antibiáticos de amplio espectro, al uso de nutrición parenteral, a la aplicación de medicamentos inmunomoduladores, [...] al transpiante de órganos y al desarrollo de las unidades de cuidado intensivo. No obstante, esto ha conllevado a la aparición de complicaciones como son las infecciones por hongos. Dentro de éstas, en los últimos años se ha demostrado que las diversas especies de cándida tienen un papel importante. La candidiasis sistémica puede ser una complicación severa en estos pacientes, con una alta morbimortalidad. En nuestro medio, desconocemos estudios donde se analice esta patología, razón por la cual se llevó a cabo este trabajo. Se estudiaron retrospectivamente los pacientes con candidiasis sistémica diagnosticados en el Hospital San Juan de Dios, hospital nacional de aproximadamente 700 camas, entre los meses de enero de 1996 a diciembre de 1998. Se analizaron 48 episodios de candidiasis sistémica en 47 pacientes. La edad promedio fue de 53 años, 60% fueron hombres. La mortalidad fue de 36%. En 77% de los pacientes se logró identificar alguna patología de base (enfermedad hematooncológica, diabetes mellitus, cirugía abdominal, enfermedad por VIH, quemaduras extensas). Los principales factores de riesgo demostrados fueron el uso previo de antibióticos de amplio espectro (87%), presencia de catéter venoso central (72%), candidiasis en otros sitios (64%), cirugía abdominal previa (25%),empleo de nutrición parenteral (23%) y uso de corticoesteroides (23%). En todos los pacientes se logró identificar al menos un factor de riesgo. Las principales especies de cándida aisladas fueron C albicans (47%), C tropicalis (19%), C parapsilosis (11%), C krusei (4%) y C glabrata (2%). Se analizó la relación entre la especie aislada y los factores de riesgo. Se encontró que C krusei y C parapsílosís se relacionaron con el uso previo de antimicóticos azoles. La mortalidad fue mayor en aquellos pacientes no tratados con antimicóticos. Se discuten estos hallazgos y se correlacionan con lo publicado en la literatura médica, llamándose la atención sobre el aumento en la incidencia de candidiasis sistémicas por candidas no aibicans. Abstract in english The mortality of patients with chronic diseases and those with agressive medical and surgical therapies has decreased in recent years, specially due to the use of broad spectrum antibiotics, parenteral nutrition, immunosupressives therapies, organ transpiantation and management of those patients in [...] intensive care units. However, new infectious diseases have emerged in this population, for example candidal infections. We do not have reports in Costa Rica about this problem. The objective of this study was to analized, retrospectiviy, demographic characteristics, risk factors, microbiologic findings, mortaiity and treatment of patients with candidal bloodstream infections between January 1996 and December 1998, in the Hospital San Juan de Dios, a costarrican reference hospital. Forty seven patients with 48 systemic candidiasis episodes met the criteria to be included in our study. Sixty percent were men and the mean age was 53 years oid. The mortality rate was 36%. All the patients presentes at least, one risk factor.The most common were the use of broad spectrum antibiotics (87%), the presence of central venous catheter(72%), candidiasis in other anatomic site (64%), previous abdominal surgery (25%),use of parenteral nutrition (23%) and neutropenia (17%). The species isolated were: C albicans (47%), C tropicalis (19%), C parapsilosis (11%), C krusei (4%) and C glabrata (2%). The last two species were related to the previous use of antimycotic azoles.

Effect of seasonal variations and collection form on antioxidant activity of propolis from San Juan, Argentina.  

Science.gov (United States)

Propolis was included in the Argentine Food Code as a functional food. The chemical parameters and antioxidant properties of propolis samples from the same colonies of Apis mellifera in San Juan (Cuyo region, Western Argentine) were compared every month for 1 year using two collection methods. Chemical parameters were analyzed by the spectrophotometric method and fingerprinting using high-performance liquid chromatography with ultraviolet detection. The antioxidant activities of propolis samples were measured using model systems including the analysis of the scavenging activities for 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals and the beta-carotene bleaching assay. The results showed that propolis had a higher free radical scavenging and lipid peroxidation inhibitory capacity than butylated hydroxytoluene and quercetin, antioxidants used in the pharmaceutical and food industries. The concentration required to scavenge 50% of free radicals (SC(50)) values differed depending on the sample collection month. Samples collected in November had the highest antioxidant capacity. In all cases, SC(50) values of propolis samples obtained by scraping were similar to those collected from a wire mesh (5 microg/mL for ABTS and 20-30 microg/mL for DPPH radicals). A significant positive correlation was found between the antioxidant capacity and flavonoid content of each analyzed extract. The chemical profiles were very similar. Galangin (3,5,7-trihydroxyflavone), an antioxidant compound, was detected in all samples as a major compound. The chromatographic profile suggests that of Baccharis sp., which would be one of the botanical sources of propolis from western Argentina, and the content of galangin can be used as a parameter for evaluating propolis quality. Our results suggest that Argentine propolis from Cuyo is a promising source of bioactive compounds as ingredients for developing functional foods with a beneficial impact on oxidative stress.

Microbiological characterization of post-eruption "snowblower" vents at Axial Seamount, Juan de Fuca Ridge  

Directory of Open Access Journals (Sweden)

Full Text Available Microbial processes within the subseafloor can be examined during the ephemeral and uncommonly observed phenomena known as snowblower venting. Snowblowers are characterized by the large quantity of white floc that is expelled from the seafloor following mid-ocean ridge eruptions. During these eruptions, rapidly cooling lava entrains seawater and hydrothermal fluids enriched in geochemical reactants, creating a natural bioreactor that supports a subseafloor microbial “bloom.” Previous studies hypothesized that the eruption-associated floc is made by sulfide-oxidizing bacteria; however, the microbes involved were never identified. Here we present the first molecular analysis combined with microscopy of microbial communities in snowblower vents from samples collected shortly after the 2011 eruption at Axial Seamount, an active volcano on the Juan de Fuca Ridge. We obtained fluid samples and white flocculent material from active snowblower vents as well as orange flocculent material found on top of newly formed lava flows. Both flocculent types revealed diverse cell types and particulates when examined by phase contrast and scanning electron microscopy. Distinct archaeal and bacterial communities were detected in each sample type through Illumina tag sequencing of 16S rRNA genes and through sequencing of the sulfide oxidation gene, soxB. In fluids and white floc, the dominant bacteria were sulfur-oxidizing Epsilonproteobacteria and the dominant archaea were thermophilic Methanococcales. In contrast, the dominant organisms in the orange floc were Gammaproteobacteria and Thaumarchaeota Marine Group I. In all samples, bacteria greatly outnumbered archaea. The presence of anaerobic methanogens and microaerobic Epsilonproteobacteria in snowblower communities provides evidence that these blooms are seeded by subseafloor microbes, rather than from microbes in bottom seawater. These eruptive events thus provide a unique opportunity to observe subseafloor microbial communitie

DINÁMICA EÓLICA E HÍDRICA EN EL SISTEMA DE MÉDANOS GRANDES, SE DE SAN JUAN, ARGENTINA  

Directory of Open Access Journals (Sweden)

Full Text Available En los sistemas sammófilos los factores ecológicos más importantes son el movimiento de arena y la disponibilidad de agua. En este trabajo se describe la dinámica eólica e hídrica en crestas e intermédanos del sistema de los Médanos Grandes de San Juan, mediante el análisis del movimiento eólico de arena, los volúmenes de arena removidos por erosión hídrica medidos en cubetas y estudios topográficos y geofísicos para determinar el perfil de humedad del suelo. En las crestas dominan los procesos eólicos, sin la formación de nebkhas y con diferencias en el movimiento de arena en función de la cobertura vegetal. Para el período de estudio en las crestas con cobertura vegetal menor al 5% el movimiento de arena fue de -0,361 m3/m, mientras que en las crestas con cobertura de hasta el 35 % fue de -0,017 m3/m. Estos ambientes presentaron resistividades entre 5000 a 6000 O.m correspondientes a menos de 0,6 gr de agua/100 gr de arena en los primeros metros de profundidad. En los intermédanos las variaciones en la depositación y erosión eólica neta para el período de estudio fue de 0,032 m3/m, mientras que la tasa media de erosión hídrica fue de 0,184m3/año. En cuanto a la disponibilidad de agua se detectaron valores de resistividad entre 500 y 700 O.m a a 5 m de profundidad que corresponden a un bulbo húmedo (agua capilar aislada con valores de 1,21g a 2g de agua/100 g de arena.

Microbial diversity within basement fluids of the sediment-buried Juan de Fuca Ridge flank.  

Science.gov (United States)

Despite its immense size, logistical and methodological constraints have largely limited microbiological investigations of the subseafloor basement biosphere. In this study, a unique sampling system was used to collect fluids from the subseafloor basaltic crust via a Circulation Obviation Retrofit Kit (CORK) observatory at Integrated Ocean Drilling Program borehole 1301A, located at a depth of 2667?m in the Pacific Ocean on the eastern flank of the Juan de Fuca Ridge. Here, a fluid delivery line directly accesses a 3.5 million years old basalt-hosted basement aquifer, overlaid by 262?m of sediment, which serves as a barrier to direct exchange with bottom seawater. At an average of 1.2 × 10(4) cells ml(-1), microorganisms in borehole fluids were nearly an order of magnitude less abundant than in surrounding bottom seawater. Ribosomal RNA genes were characterized from basement fluids, providing the first snapshots of microbial community structure using a high-integrity fluid delivery line. Interestingly, microbial communities retrieved from different CORKs (1026B and 1301A) nearly a decade apart shared major community members, consistent with hydrogeological connectivity. However, over three sampling years, the dominant gene clone lineage changed from relatives of Candidatus Desulforudis audaxviator within the bacterial phylum Firmicutes in 2008 to the Miscellaneous Crenarchaeotic Group in 2009 and a lineage within the JTB35 group of Gammaproteobacteria in 2010, and statistically significant variation in microbial community structure was observed. The enumeration of different phylogenetic groups of cells within borehole 1301A fluids supported our observation that the deep subsurface microbial community was temporally dynamic. PMID:22791235

Se indaga cómo los mapuches justificaron el sistema de [...] raciones, y sus efectos en las estructuras de poder y las relaciones interétnicas. Se discuten los antecedentes historiográficos que asociaron el malón con el tráfico ganadero hacia chile de manera lineal, para postular la centralidad de las raciones para la economía mapuche, concebidas como el pacto de gobernabilidad que habilitó los procesos formativos de los Estados provinciales y nacional en las pampas, a partir de Juan Manuel de Rosas. Esta hipótesis se sostendrá mediante la lectura de documentos escritos por los caciques, sus secretarios y las autoridades argentinas y chilenas durante el siglo XIX. Abstract in english The authors propose an anthropological and historical analysis of the policy of rationing cattle and different goods for the Pampas and Patagonian indigenous groups, implemented by the Argentinean governments between 1820 and 1880. This article explores how the Mapuche justified the rationing system [...] , and its effects on power structures and interethnic relationships. The authors also discuss the historiographic antecedents that assumed a linearly relationship between malón (Indian raids) and cattle trafficking towards Chile, in order to propose the relevance of the rations for the Mapuche economy, understanding them as the governing pact which made possible the formative processes of the provinces and the national states in the pampas since Rosas' period. Documents written by the caciques, their secretaries and the Argentine and Chilean authorities during the nineteenth century will support this hypothesis.

Nature and extent of electrogenic microbial communities recovered from Juan de Fuca hydrothermal sulfides  

Science.gov (United States)

Microbes have evolved a variety of metabolic strategies to survive in anaerobic environments, including extracellular electron transfer (EET). Here we present laboratory and in situ experiments revealing that hydrothermal vent microbes employ and depend upon EET to access spatially remote oxidants via semi-conductive pyrite. To simulate the physical and electrochemical conditions in vent sulfides, we constructed a two-chamber flow-through bioelectrochemical reactor in which a pyrite electrode was enclosed in one chamber and subject to simulated hydrothermal conditions. Electroactive biofilms formed solely on pyrite in electrical continuity with oxygenated water. Phylogenetic and metagenomic analyses revealed a diversity of autotrophic and heterotrophic archaea and bacteria, markedly different in composition from the control (pyrite without electrical continuity). To further characterize this phenomenon, we deployed a bioelectrochemical experiment in situ at the hydrothermal vent sulfide "Roane" (2200 m water depth, at the Mothra hydrothermal field, Juan de Fuca ridge). A graphite anode was inserted into a borehole drilled into the base of a hydrothermal sulfide, and connected through a potentiostat to a carbon-fiber cathode on the outside of the vent structure. The in situ experiment produced sustained current and enriched for a distinct microbial community likely associated with EET. The data presented herein reveal the nature and extent of microbial communities that use conductive minerals such as pyrite, though fully reduced, to facilitate the reduction of spatially remote oxidants while maintaining chemical discontinuity. Thus EET, by enabling sustained access to terminal electron acceptors while maintaining the functioning of strictly anaerobic metabolisms, may alleviate the limitations commonly associated with anaerobic environs, namely the depletion of oxidants.

Magmatic effects of the Cobb hot spot on the Juan de Fuca Ridge  

Science.gov (United States)

The interaction of the Juan de Fuca Ridge with the Cobb hot spot has had a considerable influence on the magmatism of the Axial Segment of the ridge, the second-order segment that overlies the hot spot. In addition to the construction of the large volcanic edifice of Axial Seamount, the Axial Segment has shallow bathymetry and a prevalence of constructional volcanic features along its 100-km length, suggesting that hot spot-derived magmas supplement and oversupply the ridge. Lavas are generally more primitive at Axial Seamount and more evolved in the Axial Segment rift zones, suggesting that fractional crystallization is enhanced with increasing distance from the hot spot because of a reduced magma supply and more rapid cooling. Although the Cobb hot spot is not an isotopically enriched plume, it produces lavas with some distinct geochemical characteristics relative to normal mid-ocean ridge basalt, such as enrichments in alkalis and highly incompatible trace elements, that can be used as tracers to identify the presence and prevalence of the hot spot influence along the ridge. These characteristics are most prominent at Axial Seamount and decline in gradients along the Axial Segment. The physical model that can best explain the geochemical observations is a scenario in which hot spot and mid-ocean ridge basalt (MORB) magmas mix to varying degrees, with the proportions controlled by the depth to the MORB source. Modeling of two-component mixing suggests that MORB is the dominant component in most Axial Segment basalts. Copyright 2005 by the American Geophysical Union.

New discoveries of early Paleocene (Torrejonian) primates from the Nacimiento Formation, San Juan Basin, New Mexico.  

Science.gov (United States)

Primates underwent a period of diversification following the extinction of non-avian dinosaurs. Although the Order first appeared near the Cretaceous-Paleogene boundary, it is not until the Torrejonian (the second North American Land Mammal Age of the Paleocene) that a diversity of families began to emerge. One of the lithological units critical to understanding this first primate adaptive radiation is the early Paleocene Nacimiento Formation of the San Juan Basin (SJB; New Mexico). Primates previously described from this formation comprise six species of palaechthonid and paromomyid plesiadapiforms, all known from very limited material. Collecting has increased the sample of primate specimens more than fivefold. Included in the new sample is the first specimen of a picrodontid plesiadapiform from the Torrejonian of the SJB, referable to Picrodus calgariensis, and the first paromomyid specimen complete enough to allow for a species level taxonomic assignment, representing a new species of Paromomys. With respect to the 'Palaechthonidae', the current report describes large collections of Torrejonia wilsoni and Palaechthon woodi, and the first new specimens attributed to Plesiolestes nacimienti and Anasazia williamsoni since 1972 and 1994, respectively. These collections demonstrate previously unknown morphological variants, including the presence of a metaconid on the p4 of some specimens of T. wilsoni, a discovery that supports previous inferences about a close relationship between Torrejonia and Plesiolestes problematicus. This new sample considerably improves our knowledge of the poorly understood 'Palaechthonidae', and about the biostratigraphy, biogeography, and early evolution of North American primates. In particular, the rarity of paromomyids, the continuing absence of plesiadapid and carpolestid plesiadapiforms, and the presence of a number of endemic palaechthonid species in the SJB contrast with plesiadapiform samples from contemporaneous deposits to the north. Together, these data suggest that by the latter part of the early Paleocene primates had already developed not only an impressive diversity, but patterns of regional endemism. PMID:23084622

Endothelial dysfunction in the San Juan hypertensive rat: possible role of the nitric oxide synthase.  

Science.gov (United States)

Endothelial dysfunction is recognized as a critical event in the etiology of cardiovascular diseases, but its possible role during aging in arterial hypertension remains poorly defined. We evaluated the response of aortic rings precontracted with 0.1 microM norepinephrine (NE) to acetylcholine (ACh) in the San Juan hypertensive rats (SJH-Rs) (F19, F20) and Munich Wistar rats (MW). SJH-Rs is a model of inbred salt-sensitive hypertension, whereas similarly treated inbred MW rats are their normotensive counterpart. These experiments were performed with adult (6-7 months) and aged (11-13 months) rats to assess the effects of age and hypertension on endothelium-dependent relaxation. We generated dose-response curves by adding cumulative doses of ACh from 1.0 nM to 10.0 microM. In addition, we evaluated the Ca(2+)-dependent nitric oxide synthase (NOS) activity by increasing cell calcium with the ionophore A23187. The results indicate that hypertension induces a displacement to the right of the dose-response curve to ACh in both adults and aged SJH-Rs; IC50 for adult rats was 0.72 +/- 0.3 microM for SJH-Rs and 0.059 +/- 0.03 microM for MW (p control animals. The displacement of the dose-response curve to ACh in SJH-Rs appears to be associated with a reduced activation of NOS since in precontracted aortas from aged animals 1 microM A23187 induced a relaxation of 51.2 +/- 12% in MW as compared with 34.4 +/- 7% in SJH-Rs (n = 5, p < 0.05). These results indicate that endothelial dysfunction exists in SJH-Rs. The data suggest that an alteration of the endothelial NOS may be the cause of this abnormality. Finally, the magnitude of the endothelial dysfunction is not age dependent within the range evaluated. PMID:8761846

Contributions to the knowledge of the geological evolution of the Atrato and San Juan basins within the arc Panama-Choco  

International Nuclear Information System (INIS)

The geological, geophysical and geochemical data pertaining the previously known as Choco Basin was compiled and reinterpreted. Today, two distinct Cenozoic basins, the Atrato Basin and the San Juan Basin are identified, each with its own geological history. They are bounded by the Istmina-Condoto Structural High, in fact, a paleo-high which intermittently acts as sedimentary barrier, i.e. source area. In the San Juan Delta Basin up to 9 km (?) of mainly clastic sediments were deposited, most probably since Paleocene time. In the Atrato Fore Arc Basin a 10 km thickness of Cenozoic sediments were seismically recorded. Both basins are sufficiently structured, as to produce potential hydrocarbon traps, mainly post-Miocene in age. The tecto-sedimentary framework in the San Juan Basin is controlled by the Istmina-Condoto Fault System in the NW and the Garrapatas Fault System in the SE. In the Atrato Basin the occurrence of growth faults is an outstanding feature.

Geology and metallogeny of the volcanic complex of Rio Blanco Ullum. Province of San Juan. Republica Argentina  

International Nuclear Information System (INIS)

Preliminary results of a research carried out at the Complejo Rio Blanco de Ullum, San Juan. Argentina are summarized in the present paper. These studies are focused on geological and metallogenic features o f this unit. The study area is located 20 km. WNW of San Juan city with geographic coordinates of 31grades 30' South latitude and 68 grades 52' West longitude. The older rocks aotcroping in the area correspond to limestones of Ordovician San Juan Formation, the chronologic succession continues with sales and siltstones of Silurian Tambolar Formation, pelites and subgraywackes of Devonian Punta Negra Formation and finally a 1500 m thick package of piroclastics and sediments of Albarracin Formation of Tertiary age. Albarracin Formation is composed pf a Basal Member (sandstones and stilstones), a Tuffaceous Member (tuffs, tuffites and oligomictic breccia s with conglomerate interbed dings in the upper part) and a Conglomeratic Member (polimictic para conglomerates). According to piroclastics facies, relationships and spreading area of piroclastics deposits a colapsed dome and avalanche model is proposed to be the main process for the piroclastics package outcropping in the area.Sedimentary and piroclastics rocks are intruded by five sub volcanic units as noted by Leveratto (1968) which are composed by different lithologies such as: Altered Da cite - Rhyolite, Ullum Da cite, Cerro Blanco de Zonda Andesite, Ullum Andesite and Hybrid Andesite.Detailed work on alteration assemblages and metallogenic features in the southwestern sector of the Complejo resulted in the identification of three alteration zones with characteric features of potassic, argillic and propyllitic signature.

Shallow structure and surface wave propagation characteristics of the Juan de Fuca plate from seismic ambient noise  

Science.gov (United States)

Ambient noise cross-correlation analysis has been widely used to investigate the continental lithosphere, but the method has been applied much less to study the oceanic lithosphere due to the relative shortage of continuous ocean bottom seismic measurements. The Cascadia Initiative experiment possesses a total of 62 ocean bottom seismometers that spans much of the Juan de Fuca plate and provides data to investigate both the structure and evolution of the oceanic lithosphere near the Juan De Fuca ridge and the characteristics of surface waves and overtones propagating within the oceanic lithosphere. We produce ambient noise cross correlations for the first year of Cascadia OBS data for both the vertical and the horizontal components. The observed empirical Green's functions are first used to test the hypothesis that the near-ridge phase speeds can be described by a simple age-dependent formula, which we invert for an age-dependent shear wave speed model (Figure 1a). A shallow low shear velocity zone with a velocity minimum at about 20km depth is observed in Vsv and the lithosphere thickens with age faster than predicted by a half-space conductive cooling model (Figure 1b). To further understand the oceanic surface waves, we analyze the first higher mode Rayleigh waves that propagate within the Juan De Fuca plate and emerge on the North American continent and investigate the existence of radial anisotropy beneath the ridge by exploring the Rayleigh and Love wave Green's functions. The results of the study are summarized with the age-dependent shear velocity model along with some preliminary observations of both Love wave and higher mode Rayleigh waves.
