'Geoscientific research' performed at the Tono Geoscience Center is developing site investigation, characterization and assessment techniques for understanding of geological environment. Their important themes are to establish a methodology for analyzing uncertainties in heterogeneous geological environment, and to develop investigation techniques for reducing the uncertainties efficiently. This study proposes a new approach where all the possible options in the models and data-sets that cannot be excluded in the light of the evidence available, are identified. This approach enables uncertainties associated with the understanding at a given stage of the site characterization to be made explicitly using an uncertainty analysis technique based on Fuzzy geostatistics. This, in turn, supports the design of the following investigation stage to reduce the uncertainties efficiently. In the study, current knowledge had been compiled, and the technique had been advanced through geological modeling and groundwater analyses in the Tono area. This report systematized the uncertainty analysis methodology associated with the characterization of the geological environment, and organized the procedure of the methodology with the application examples in the study. This report also dealt with investigation techniques for reducing the uncertainties efficiently, and underground facility design options for handling geological uncertainties based on the characterization of the geological environment.

To compare central corneal thickness (CCT) measured by standard ultrasound pachymetry (USP), and three non-contact devices in healthy eyes. A cross-sectional study of CCT measurement in 52 eyes of 52 healthy volunteers was done by a single examiner at Ocular Surface and Contact Lens Laboratory. Three consecutive measurements were done by standard USP, non-contact tono-pachymeter, Pentacam corneal topographer, and Anterior Segment Optical Coherence Tomography (AS-OCT). The mean values were used for assessment. The results were compared using multivariate ANOVA, linear regression, and Pearson correlation. Agreement among the devices was analyzed using mean differences and Bland-Altman analysis with 95% limits of agreement (LoA). Finally, reliability was analyzed using intraclass correlation coefficient (ICC). Mean CCT by ultrasound pachymeter, tono-pachymeter, corneal topographer and AS-OCT were 558.9 ± 31.2 µm, 525.8 ± 43.1 µm, 550.4 ± 30.5 µm, and 545.9 ± 30.5 µm respectively. There was a significant positive correlation between AS-OCT and USP (Pearson correlation = 0.957, p device, and USP. Mean CCT among USP, Pentacam and AS-OCT were comparable and had significant linear correlations. In clinical practice, these three modalities could be interchangeable in healthy patients.

Rethinking of the criteria for natural analogue study. A case of Tono natural analogue study

Natural analogue regarding long-term performance of the geological disposal system for radioactive waste isolation is essentially the study of geochemical process which has been evolved in geological environment. All geochemical studies, however, will not be nominated as natural analogue studies. It is, therefore, important to be clear the criteria for natural analogue study with the view of analogy by following three categories, (1) Conceptual model development, (2) Data provision and (3) Model testing, for the concept of geological disposal and safety assessment model. Rethinking of the criteria for natural analogue study through the case of Tono Natural Analogue Study, and the usefulness of natural analogue study for the safety assessment of geological disposal system in Japan have been presented in this paper.

Study on dose assessment in surrounding environment of the Tono Mine associated with closure activity

International Nuclear Information System (INIS)

Sasao, Eiji

2012-07-01

Dose assessment associated with closure activity of the Tono Mine has been performed. In this assessment, exposure dose has been calculated on groundwater and surface water migration of radionuclide from 1) waste rock in the waste rock dump facility, 2) mining waste in the mining waste facility, and 3) uranium ore and waste rock backfilled in the shafts and galleries. Direct and skyshine gamma rays and exposure of exhalated radon from the waste rock dump has also been evaluated. An evaluation tool developed for safety assessment for sub-surface disposal of radioactive waste is utilized for this assessment. Localities for dose evaluation are selected at the Higashihoragawa and Hiyoshigawa based on the topography around the Tono Mine and groundwater flow simulation. Evaluation scenarios are classified into 'Scenario for intake of agricultural product' as the base scenario, and 'Scenario for intake of groundwater' as the alternative scenario. Parameters for dose assessment are set-up based on the existing data. But the range and uncertainty of parameters are taken into account in the 'alternative cases'. As the result of dose assessment, maximum exposure dose of the base scenario is 0.08mSv/year, and 0.09mSv/year including direct and skyshine gamma rays and exposure of exhalatedradon at the Higashihoragawa. Maximum exposure dose of the alternative scenario is 0.08mSv/year (0.09mSv/year including direct and skyshine gamma rays and exposure of exhalated radon). On the alternative cases, exposure doses are calculated as 0.05-0.14mSv/year in both of the base and alternative scenarios. At the Hiyoshigawa, maximum exposure dose is less than 0.001mSv/year (1x10 -6 mSv/year) for the base scenario, and 0.001mSv/year for the alternative scenario. On the alternative cases, maximum exposure doses are less than 0.001mSv/year for all cases of the base scenario and 0.0006-0.002mSv/year for the alternative scenario. (author)

Natural analogue study of uranium deposits in Japan with special reference to the Tono uranium deposit

In order to verify the safety assessment for geological disposal system of high-level radioactive waste, it is necessary to evaluate properly the stability of the disposal system under natural hydrogeological environment over long period of time (ten to hundred thousands years). For the safety assessment for that in the Japanese Islands, many geological processes inherent in the tectonically active Island-Arc system should be also taken into consideration in addition to those in stable continental environment. However, it is difficult because some processes such as earthquake seem to be accidental and some are periodic or gradual over our life scale. The uranium deposits in Japan are subjected to many geological processes inherent in the tectonically active Island-Arc system. The studies on long-term preservation of uranium deposits in Japan from a natural analogue viewpoint would be expected to provide useful information for the assessment in the Japanese Islands over long period of time. In order to understand the behavior of radionuclides under natural hydrogeological environment in Japanese Islands over long period of time, the uranium deposits in Japan, especially of the Tono uranium deposit was investigated from a natural analogue viewpoint under the course of joint research program by University of Tsukuba and Japan Nuclear Cycle Development Institute. Important conclusions obtained in the present study are summarized as follows: The migration behavior of the radionuclides in the granite area is mainly controlled by the stability of original minerals in oxic condition, being due to poor reducing agents such as organic matter and sulfide minerals. In the case of hydrothermal alteration, yttrialite and fergusonite were decomposed and thorogummite was formed at the altered part, whereas zircon and allanite have not been significantly altered. In the case of weathering, autunite and torbernite were formed, probably due to the high phosphorus weathering

Numerical models are powerful tools for the characterization of groundwater flow, especially when integrating geochemical and hydrogeological data. This paper describes modeling exercises performed in the area surrounding the Mizunami Underground Research Laboratory (MIU) Construction Site in central Japan. A particular issue being investigated at the MIU Site is the presence of saline water detected at depth in certain boreholes. The main objective of this study is to develop conceptual physical models for the origin of this salinity and to test these conceptual models using numerical modeling techniques. One scenario being investigated is that the saline fluids represent residual Miocene age seawater which has been slightly altered by water-rock interactions. It is likely that during Miocene times, seawater inundated the Tono area. This hypothesis is partially supported by carbon and oxygen isotopic data of the calcite fracture filling materials.

2017-08-01

Full Text Available Water resources are a major source of economic development for most West African (WA countries. There is, however inadequate information on these resources for the purposes of planning, decision-making and management. This paper explores the potential for using a state of the art hydrological model (WRF-Hydro in a fully coupled (i.e. land surface hydrology-atmosphere mode to assess these water resources, particularly the Tono basin in Ghana. The WRF-Hydro model is an enhanced version of the Weather Research and Forecasting model (WRF which allows simulating river discharge. A 2-domain configuration is chosen: an outer domain at 25 km horizontal resolution encompassing the West African Region and an inner domain at 5 km horizontal resolution centered on the Tono basin. The infiltration partition parameter and Manning’s roughness parameter were calibrated to fit the WRF-Hydro simulated discharge with the observed data. The simulations were done from 1999 to 2003, using 1999 as a spin-up period. The results were compared with TRMM precipitation, CRU temperature and available observed hydrological data. The WRF-Hydro model captured the attributes of the “observed” streamflow estimate; with Nash-Sutcliff efficiency (NSE of 0.78 and Pearson’s correlation of 0.89. Further validation of model results is based on using the output from the WRF-Hydro model as input into a water balance model to simulate the dam levels. WRF-Hydro has shown the potential for use in water resource planning (i.e. with respect to streamflow and dam level estimation. However, the model requires further improvement with respect to calibration of model parameters (e.g. baseflow and saturated hydraulic conductivity considering the effect of the accumulation of model bias in dam level estimation.

este problema consiste en la clasificación del producto en función de sus características visuales, lo que tradicionalmente se realiza de forma manual: un operario observa cada pieza y la asigna a uno de los tipos considerados en función de parámetros visuales tales como color, textura, grano, veteado, etc. Sin embargo, esta labor presenta a su vez problemas de consistencia, debidos a la subjetividad del criterio de clasificación de cada operario, y a los errores provocados por su progresiva fatiga. Los intentos de aplicar sistemas de inspección automática genéricos como los utilizados en la industria cerámica han resultado fallidos debido a que la piedra natural presenta una variabilidad mucho mayor que las baldosas cerámicas. Por ello, ha sido necesario desarrollar sistemas de clasificación específicamente diseñados para el tratamiento de los ámetros visuales que diferencian los distintos tipos de piedra natural. A continuación se describe los pormenores del sistema de visión artificial desarrollado por AITEMIN para la clasificación automática de piezas de granito en función de su tono, que permite dar una solución integral a la problemática del control de tono en la industria de elaboración y comercialización de granitos. El sistema ha sido diseñado para ser entrenado fácilmente por el usuario final, mediante el aprendizaje de las muestras seleccionadas como patrones de tono.

Kobayashi, Koichi; Nakano, Katushi; Koide, Kaoru

1996-01-01

The groundwater flow analysis involve the groundwater recharge from the subsurface to the rock mass. According to water balance method, annual groundwater recharge is calculated by the remainder of annual evapotranspirator and river flow from annual precipitation. In this estimation, hydrological and meteorological data observed for 5 years on the watershed in Tono mine area is used. Annual precipitation ranges from 1,000 to 1,900 mm and annual river flow ranges from 400 to 1,300 mm, then river flow depends critically on precipitation. Annual evapotranspiration calculated by Penman method ranges from 400 to 500 mm. It is less fluctuant than annual precipitation. As the result of examination of water balance in subsurface zone estimated, annual ground water recharge ranges from 10 to 200 mm in this watershed. (author)

The purpose of the study was to compare the levels of the intraocular pressure (NOT) measured in one eye at the same moment by three different methods: by Goldmann applanation tonometer (AT), non-contact tonometer (BT) and Tono-Pen (TP). It was further set the average variability of the performed measurements for particular tonometric methods. NOT was assessed in 106 eyes of 106 subjects aged 7-77 years (average 34.3 +/- 17.1 years). NOT was measured at the same moment with BT, TP and AT. The obtained data were statistically analyzed. The average NOT was 16.55 +/- 2.95, 17.95 +/- 4.47 and 16.13 +/- 3.4 mmHg when AT, BT and TP were applied. Average variability of three measurements for AT, BT and TP was 1.51 +/- 0.96, 1.78 +/- 1.08 and 1.47 +/- 0.9 mmHg. Average NOT levels of the measured AT and TP were almost identical with a difference of 0.42 mmHg (p = 0.236). Average level of the intraocular pressure measured by BT was higher by 1.40 mmHg and 1.82 mmHg in comparison with AT and TP (p = 0.00002), respectively. NOT measurement produced almost identical average levels at AT and TP, whereas at BT the levels were much higher. Average variability of the three subsequent NOT measurements was the highest at BT, whereas at AT and TP the average variability was lower and nearly identical.

Hydrochemical investigation of Tertiary sedimentary rocks at JNC's Tono in-situ tests site indicate the groundwaters are: meteoric in origin, chemically reducing at depths greater than a few tens of meters in the sedimentary rock, relatively old [carbon-14 ages of groundwaters collected from the lower part of the sedimentary sequence range from 13,000 to 15,000 years BP (before present)]. Ca-Na-HCO 3 type solutions near the surface, changing to Na-HCO 3 type groundwaters with increasing depth. The chemical evolution of the groundwaters is modeled assuming local equilibrium for selected mineral-fluid reactions, taking into account the rainwater origin of these solutions. Results suggest it is possible to interpret approximately the 'real' groundwater chemistry (i.e., pH, Eh, total dissolved concentrations of Si, Na, Ca, K, Al, carbonate and sulfate) if the following assumptions are adopted: CO 2 concentration in the gas phase contacting pore solutions in the overlying soil zone=10 -1 bar, minerals in the rock zone that control the solubility of respective elements in the groundwater include; chalcedony (Si), albite (Na), kaolinite (Al), calcite (Ca and carbonate), muscovite (K) and pyrite (Eh and sulfate). It is noted, however, that the available field data may not be sufficient to adequately constrain parameters in the groundwater evolution model. In particular, more detailed information characterizing certain site properties (e.g., the actual mineralogy of 'plagioclase', 'clay' and 'zeolite') are needed to improve the model. Alternative conceptual models of key reactions may also be necessary. For this reason, a model that accounts for ion-exchange reactions among clay minerals, and which is based on the results of laboratory experiments, has also been evaluated in the present study. Further improvements of model considering ion-exchange reactions are needed in future, however. (author)

WE AIMED TO COMPARE INTRAOCULAR PRESSURE (IOP) MEASUREMENTS VIA THREE DIFFERENT TONOMETERS: the Goldmann applanation tonometer (GAT), the Tono-Pen(®) XL (TPXL), and a non-contact airpuff tonometer (NCT). This was a cross-sectional study of 200 eyes from 200 patients. Right eyes of all patients were included in this study. IOP was measured via GAT, NCT, and TPXL by three physicians. Each physician used one of the tonometers. Measurements via the three devices were compared. The mean IOP was 15.5±2.2 mmHg (range 10-22) with the GAT, 16.1±3.0 (range 9-25) with the TPXL, and 16.1±2.8 (range 10-26) with the NCT. Bland-Altman analysis showed that the mean difference between measurements from the NCT and the GAT was 0.6±2.3 mmHg. The mean difference between the TPXL and GAT measurements was 0.7±2.5 mmHg. The mean difference between the NCT and TPXL measurements was -0.02±3.0 mmHg. There was no significant difference between the groups according to a one-way analysis of variance (ANOVA) test. P-values were 0.998 for NCT-TPXL, 0.067 for NCT-GAT, and 0.059 for TPXL-GAT. The NCT and TPXL provide IOP measurements comparable to those of the gold standard GAT in normotensive eyes.

To compare and evaluate the accuracy of intraocular pressure (IOP) measured through a therapeutic contact lens, using applanation (TonoPen XL(®)) and rebound (TonoVet(®)) tonometers in enucleated dog eyes. A total of 30 enucleated eyes from 15 beagle dogs. To measure accurate IOP, the anterior chamber of each enucleated eye was cannulated with two 26-gauge needles and two polyethylene tubes were connected vertically to an adjustable reservoir bag of normal saline and a pressure transducer. IOP was measured by the TonoPen XL(®) followed by the TonoVet(®) without a contact lens. After a contact lens was applied to the cornea, IOP was re-measured in the same order. Three consecutive IOP measurements were performed using both tonometers. Without the contact lens, the IOP values obtained by both tonometers correlated well according to the regression analysis (TonoVet(®): γ(2) = 0.98, TonoPen XL(®): γ(2) = 0.97, P contact lens was applied to the cornea. Bland-Altman analysis was used to determine the lower and upper limits of agreement (TonoVet(®): -29.7 and +21.1 mmHg, TonoPen XL(®): -3.9 and +3.6 mmHg) between the two devices. This study suggests that the TonoPen XL(®) is a useful tonometer for dogs wearing therapeutic contact lenses, and importantly, contact lenses would not need to be removed prior to IOP measurement. © 2012 American College of Veterinary Ophthalmologists.

To evaluate feasibility and accuracy of intraocular pressure (IOP) measurement by rebound tonometry in adult red-eared slider turtles and determine the effects of manual and chemical restraint on IOP. Seventeen adult red-eared slider turtles. Intraocular pressure was measured with TonoLab® and TonoVet® tonometers in conscious, unrestrained turtles. To evaluate the effects of manual restraint, turtles were restrained by digital pressure on the rostral head or proximal neck. The effect of two chemical restraint protocols (dexmedetomidine, ketamine, midazolam [DKM] and dexmedetomidine, ketamine [DK] subcutaneously) on IOP was evaluated. Triplicate TonoLab® and TonoVet® readings were compared with direct manometry in three ex vivo turtle eyes. TonoLab® correlated better with manometry at IOPs < 45 mmHg than TonoVet® (linear regression slopes of 0.89 and 0.30, respectively). Mean (±SD) IOP in unrestrained conscious turtles was significantly lower (P < 0.01) with TonoLab® (10.02 ± 0.66 mmHg) than with TonoVet® (11.32 ± 1.57 mmHg). Manual neck restraint caused a significant increase in IOP (+6.31 ± 5.59 mmHg), while manual rostral head restraint did not. Both chemical restraint protocols significantly reduced IOP (DKM: −1.0 ± 0.76 mmHg; DK: −1.79 ± 1.17) compared with measurements in conscious unrestrained turtles. Chemical and manual neck restraint affected IOP. Rostral head restraint had no significant effect on IOP and is, therefore, recommended as the appropriate restraint technique in red-eared slider turtles. TonoLab® measurements estimated actual IOP more accurately, within physiologic range, than measurements obtained using the TonoVet®. © 2013 American College of Veterinary Ophthalmologists.

To analyze the correlation of Goldmann applanation tonometer (GAT), I-Care tonometer and Tono-Pen tonometer results in young healthy persons, and to investigate the influence of central corneal thickness (CCT) on intraocular pressure (IOP) measurements recorded with these tonometers. We conducted a pilot clinical study in 78 eyes of 78 subjects aged 22-28 years old (44 women and 34 men; mean age 23.8±1.19y). IOP was measured using GAT, I-Care and Tono-Pen tonometers, followed by measurements of CCT. Statistical analysis was performed using SPSS 20.0. The mean IOPs and standard deviation (±SD) for GAT, I-Care and Tono-Pen were 15.62±2.281 mm Hg, 16.29±2.726 mm Hg and 16.32±2.393 mm Hg, respectively. The mean CCT was 555.15±29.648 µm. Clear positive correlations between GAT and I-Care, GAT and Tono-Pen, and I-Care and Tono-Pen tonometers were found (r=0.867, P0.05). Both non-gold standard tonometers were affected by CCT; that is, both I-Care and Tono-Pen tonometer values were significantly higher with higher CCT means (>555 µm; MD=-1.282, Ptonometers overestimated IOP compared with the GAT values. Either the I-Care or Tono-Pen tonometer could be used instead of GAT because there was no significant difference between their results. Higher CCT values (>555 µm) were associated with overestimated IOP values.

The purpose of this prospective study was to describe intraocular pressure (IOP) and examination findings in three tree frog species (Cruziohyla craspedopus [fringe leaf frog], Cruziohyla calcarifer [splendid leaf frog], and Anotheca spinosa [spiny-headed or coronated tree frog]). Thirty-one C. craspedopus, four C. calcarifer, and five A. spinosa were weighed, sexed based on phenotype where possible, and examined using slit-lamp biomicroscopy and indirect ophthalmoscopy. IOP was measured using the TonoVet and TonoLab rebound tonometers while the frogs were held two ways (unrestrained, then restrained). Statistical differences were determined using one-way analysis of variance (ANOVA) and t-tests. Mean ± SD IOP (TonoVet and TonoLab, respectively) was 15.1 ± 2.5 mmHg and 15.6 ± 4.1 mmHg in C. craspedopus; 14.8 ± 1.5 mmHg and 18.8 ± 3.1 mmHg in C. calcarifer; and 9.1 ± 2.1 mmHg and 10.8 ± 1.4 mmHg in A. spinosa. There was no significant difference in IOP in C. craspedopus by eye (Right vs Left), tonometer, or restraint method. IOP in female C. craspedopus was 1-3 mm Hg higher than in males with both devices (P Cruziohyla genus frogs and A. spinosa for the TonoVet (P < 0.05). There was no difference in IOP measurements between the TonoVet and TonoLab in C. craspedopus. IOP varied by gender in C. craspedopus and between species, but not by tonometer. Ocular abnormalities were minimal in this group of captive bred frogs.

To determine the accuracy and reproducibility of intraocular pressure (IOP) measurements obtained with the TonoVet® rebound tonometer in cynomolgus macaques and to determine the effects of corneal thickness on measurements obtained by the TonoVet®. The anterior chambers of both eyes of anesthetized monkeys were cannulated with branched 23-G needles; one branch was connected to a vertically adjustable reservoir and the other to a pressure transducer. IOP was increased by 5 mmHg increments and then decreased by 10 mmHg decrements. IOP was measured using the TonoVet® at each increment and decrement by 2 independent observers and at every other increment and every decrement by a single observer using 'minified' Goldmann applanation tonometry. Central corneal thickness was measured with a PachPen(TM) ultrasonic pachymeter. TonoVet® readings correlated well with manometric IOP (slope = 0.972, r(2) coefficient = 0.955). No significant differences were observed when comparing eyes or operators; however there was a non-significant trend for TonoVet® readings taken in right eyes to be closer to manometric IOP than those taken in left eyes. The TonoVet® had a non-significant tendency to underestimate manometric IOP. TonoVet® readings obtained during the decremental phase of the experiment were significantly closer (p tonometer is a reliable and accurate tool for the measurement of IOP in cynomolgus macaques. This tonometer has several advantages, including portability, ease of use, and brief contact with the corneal surface making topical anesthetics unnecessary. Copyright © 2011 Elsevier Ltd.

To identify the correlation between the difference of intraocular pressure measurements (IOP) obtained using the Goldmann applanation tonometer (GAT) and three others tonometers (Handheld applanation tonometer - HAT, Dynamic contour tonometer - DCT and Tono-Pen®) with biometric characteristics (corneal diameter, pachymetry, keratometry and axial length) in patients with congenital glaucoma. A cross-sectional study was performed on 46 eyes from 46 patients with congenital glaucoma. IOP measurements were obtained in all patients using GAT, HAT, DCT and Tono-Pen®. Keratometry, pachymetry, biometry and corneal diameter measurements were performed after the IOP measurement. The order of the tonometries was randomized. The correlations between the differences of IOP values of GAT and the other tonometers (Delta-IOP), and the different biometric parameters were studied. Tono-Pen® Delta IOP revealed moderate positive correlation to keratometry (r=0.41, p=0.004). The other Delta-IOPs showed no correlation with any of the biometric characteristics evaluated. IOP differences between GAT (gold standard) and GAT, HAT, DCT or Tono-Pen tonometers seem not to correlate with majority of ocular biometric characteristics. The only exception was the keratometry, which correlated in a positive and moderate way with Tono-Pen® Delta-IOP. This result suggests that the differences of IOP values of Tono-Pen® and GAT increase with the steepness of the cornea.

Intraocular pressure is affected by corneal thickness and biomechanics. Following ablative corneal refractive surgery, corneal structural changes occur. The purpose of the study is to determine the relationship between the mean central corneal thickness (CCT) and the change in intraocular pressure measurements following various corneal ablation techniques, using different measurement methods. Two hundred myopic eyes undergoing laser in situ keratomileusis (LASIK) or photorefractive keratectomy (PRK) were enrolled into a prospective, non-randomized study. Corneal parameters examined included full ocular examination, measurement of CCT, corneal topography, corneal curvature and ocular refractivity. Intraocular pressure measurements were obtained using three different instruments-non-contact tonometer, Goldmann applanation tonometer and TonoPen XL (TonoPen-Central and TonoPen-Peripheral). All measurements were performed pre-operatively and 4 months post-operatively. Post-operative intraocular pressure was significantly lower than pre-operative values, with all instruments (p value tonometer and non-contact tonometer (p value < 0.001, ANOVA). Intraocular pressure readings are significantly reduced following corneal ablation surgery. We determined in our myopic patient cohort that the TonoPen XL intraocular pressure measurement method is the least affected following PRK and LASIK as compared to other techniques.

N-nitrosamines are a group of potent human carcinogens that can be formed during oxidative treatment of drinking water and wastewater. Many tertiary and quaternary amines present in consumer products (e.g., pharmaceuticals, personal care and household products) are known to be N-nitrosodimethylamine (NDMA) precursors during chloramination, but the formation of other N-nitrosamines has been rarely studied. This study investigates the specific and total N-nitrosamine (TONO) formation potential (FP) of various precursors from nitrogen-containing micropollutants (chlorhexidine, metformin, benzalkonium chloride and cetyltrimethylammonium chloride) and tertiary and quaternary model amines (trimethyl amine, N,N-dimethylbutyl amine, N,N-dimethylbenzyl amine and tetramethyl ammonium). All the studied nitrogenous micropollutants displayed quantifiable TONO FP, with molar yields in the range 0.04-11.92%. However, the observed TONO pools constituted mostly of uncharacterized species, not included in US-EPA 8270 N-nitrosamines standard mix. Only the quaternary ammonium compound benzalkonium chloride showed quantifiable NDMA FP (0.56% molar yield), however, explaining only a minor fraction of the observed TONO FP. The studied model amines showed molar NDMA yields from 0.10% (trimethyl amine) to 5.05% (N,N-dimethylbenzyl amine), very similar to the molar TONO yields. The comparison of the FPs of micropollutants and model compounds showed that the presence of electron donating functional groups (such as a benzyl group) in tertiary and quaternary amine precursors leads to a higher formation of NDMA and uncharacterized N-nitrosamines, respectively. LC-qTOF screening of a list of proposed N-nitrosamine structures has enabled to identify a novel N-nitrosamine (N-nitroso-N-methyldodecylamine) from the chloramination of benzalkonium chloride. This finding supports the hypothesis that different functional groups in quaternary amines can act as leaving groups during chloramination and

The ICare (Tiolat Oy, Helsinki, Finland) is a new portable tonometer that measures intraocular pressure (IOP) with a new rebound method, in which a very light probe is used to make momentary contact with the cornea in slow motion. The purpose of this study is to assess the accuracy of the ICare IOP measurements by comparing them against other portable tonometers: Perkins applanation tonometer and Tono-Pen XL digital tonometer (Medtronic Solan, Jacksonville, FL). Sixty-five young subjects were assessed with each of the tonometers. ICare tonometry was performed first, followed by Perkins applanation tonometry and Tono-Pen XL in a random order. Regression analysis was used to evaluate the relationship between the Perkins tonometer and the remaining tonometers used in this study. Tonometers were also compared by plotting the difference between the methods against the mean. The hypothesis of zero bias was examined by a paired t test and the 95% limits of agreement (LoA) were calculated. ICare and Tono-Pen XL significantly overestimate IOP when compared with Perkins applanation tonometry. The mean of the difference between Perkins and ICare and Perkins and Tono-Pen XL was (mean +/- standard deviation) -3.35 +/- 2.28 mm Hg and -2.78 +/- 2.53 mm Hg, respectively. The 95% LoA between Perkins tonometry and ICare tonometry were between -7.81 and +1.12 and between Perkins tonometry and Tono-Pen XL tonometry between -7.74 and +2.18. Compared with Perkins tonometry, the ICare tonometer allows clinicians to estimate IOP with a portable, rapid, and noninvasive method with similar reliability to that offered by Tono-Pen XL. Clinicians should be aware of the systematic overestimation of IOP with the ICare. Further research is needed to evaluate the performance of rebound tonometry in populations with higher IOP and assess the reliability of this technique in the early detection and follow up of glaucomatous patients.

The Tono Geoscience Center is carrying out the Mizunami Underground Research Laboratory Project (MIU Project), as part of its scientific research program, in Mizunami City, Gifu Prefecture. We believe that the public and especially the local residents should have a precise understanding of the MIU project. Therefore, to provide information we have used virtual reality (VR) technology in the project since 1996. Software to introduce both the MIU Project and the geology of the Tono district has been completed. The Tono district is characterized by uranium ore deposits, and by clay deposits which are used by the pottery industry. Software with some amusement value, such as hot spring drilling, has also been completed. We plan further software development of VR technology to increase the feeling of realism. (author)

IOP measurements were compared and the effects of head position and presence of contact lenses on the resultant values were analyzed. the average difference between the recumbent and sitting positions was 3.56, 2.68, and 2.62 mm Hg for the Tono-Pen tonometer, Phosphene tonometer, and TERT, respectively. There was an increase of 5.60, 2.78, and 2.63 mm Hg in hyperextension compared to sitting for the Tono-Pen tonometer, Phosphene tonometer, and TERT, respectively. The difference in the IOP values obtained in the presence and absence of therapeutic contact lens for the three instruments in the three positions was between -1.23 and +1.47 mm Hg. IOP measurements of bedridden patients are only slightly higher than those of sitting patients except for the Tono-Pen tonometer in the hyperextension position. The presence of contact lenses does not affect IOP values obtained by the three evaluated instruments.

The data was analyzed with descriptive statistics, paired  t-test, correlation and regression analysis. The Bland-Altman method of analysis was used to evaluate agreements between the sets of data from the three devices. The CCT values ranged from 440 µm to 606 µm (mean= 518.49 ± 33.01 µm. There was little or no correlation between CCT and IOP for any of the instruments used in this study (r = 0.29 for Tonopachy™, r = 0.22 for iCare®, r = 0.17 for GAT. The mean IOP measured with the Tonopachy™ was 14.31 ± 3.57 mmHg (range 8.7 mmHg to 31 mmHg and 16.64 ± 4.38 mmHg (range 8 mmHg to 32 mmHg using the iCare®. The mean IOP measured with the GAT was 14.79 ± 3.09 mmHg (range 8.7 mmHg to 29.7 mmHg. Using the Bland-Altman method, the upper and lower limits of agreement between the Tonopachy™ and GAT, iCare® and GAT, iCare® and Tonopachy™ were 5.1 mmHg and –4.2 mmHg, 8.6 mmHg and –4.9 mmHg, 7.5 mmHg and –2.8 mmHg respectively. In 79.1% of the eyes studied, the mean IOP difference between Tonopachy™ and GAT was less than 3 mmHg and in 20.9% of the eyes, the difference was greater than 3 mmHg. However, mean IOP differences of greater than 3 mmHg were obtained by iCare® in comparison with GAT (40% and Tonopachy™ (34.3% respectively. Findings of this study suggest that the Tonopachy™ yielded IOP readings that were consistent with those of GAT values while iCare® yielded higher IOP values compared to both GAT and Tonopachy™.

Purpose To evaluate the usefulness of the TonoVet™ rebound tonometer in measuring intraocular pressure (IOP) of monkeys. Methods The accuracy of the TonoVet™ rebound tonometer was determined in cannulated eyes of anesthetized rhesus monkeys where IOP was controlled by adjusting the height of a connected perfusate reservoir. To assess the applicability of the equipment through in vivo studies, the diurnal fluctuation of IOP and effects of IOP-lowering compounds were evaluated in monkeys. Results IOP readings generated by the TonoVet™ tonometer correlated very well with the actual pressure in the cannulated monkey eye. The linear correlation had a slope of 0.922±0.014 (mean±SEM, n=4), a y-intercept of 3.04±0.61, and a correlation coefficient of r2=0.97. Using this method, diurnal IOP fluctuation of the rhesus monkey was demonstrated. The tonometer was also able to detect IOP changes induced by pharmacologically active compounds. A single topical ocular instillation (15 μg) of the rho kinase inhibitor, H1152, produced a 5–6 mmHg reduction (pmonkey eye. PMID:19898690

LLNL Underground-Coal-Gasification Project. Quarterly progress report, July-September 1981

We have continued our laboratory studies of forward gasification in small blocks of coal mounted in 55-gal drums. A steam/oxygen mixture is fed into a small hole drilled longitudinally through the center of the block, the coal is ignited near the inlet and burns toward the outlet, and the product gases come off at the outlet. Various diagnostic measurements are made during the course of the burn, and afterward the coal block is split open so that the cavity can be examined. Development work continues on our mathematical model for the small coal block experiments. Preparations for the large block experiments at a coal outcrop in the Tono Basin of Washington State have required steadily increasing effort with the approach of the scheduled starting time for the experiments (Fall 1981). Also in preparation is the deep gasification experiment, Tono 1, planned for another site in the Tono Basin after the large block experiments have been completed. Wrap-up work continues on our previous gasification experiments in Wyoming. Results of the postburn core-drilling program Hoe Creek 3 are presented here. Since 1976 the Soviets have been granted four US patents on various aspects of the underground coal gasification process. These patents are described here, and techniques of special interest are noted. Finally, we include ten abstracts of pertinent LLNL reports and papers completed during the quarter.

To compare the reliability and accuracy of intraocular pressure (IOP) measured while wearing soft contact lenses (SCLs) using a non-contact tonometer (NCT), Goldmann applanation tonometer (GAT), iCare rebound tonometer (RBT) and the Tono-Pen XL. Twenty-six healthy subjects were examined. The IOP was measured using NCT, GAT, RBT, and the Tono-Pen XL, while the subjects wore SCLs -5.00 D, -0.50 D and +5.00 D. Bland-Altman plots and a regression analysis were used to compare the IOPs obtained with those instruments and the IOPs of the naked eyes measured using GAT (the standard IOPs in this study). The IOPs obtained by the Tono-Pen XL while the subjects were wearing -5.00 D, -0.50 D, and +5.00 D SCLs were significantly higher than those of the naked eyes obtained using GAT. RBT showed that the IOPs were similar to the GAT standard IOPs under all conditions. The IOPs measured with NCT and GAT while the subjects were wearing -5.00 D and -0.50 D SCLs were similar to the GAT standard IOPs. The IOPs obtained with RBT and NCT while the subjects were wearing -5.00 D and -0.50 D SCLs exhibited a good correlation with the standard IOPs. The NCT and RBT are best when measuring IOP through hydrogel SCLs.

In the fiscal year of 2003, our committee achieved the following work items during the contract period, from September 3rd, 2003 to February 13th, 2004. The more accurate numerical data with respect to the geological/geometrical conditions including the fault were provided from Tono Geoscience Center and the numerical models by Finite Element Method (FEM), Finite Difference Method (FDM) and Boundary Element Method (BEM) were built taking those strata data into account. For small region modeling by FEM, three layers models, Shoumasama model and Tono-Shoumasama model, as well as Tono Mine model, were constructed, and each strain state at the far field boundary was determined. In order to get better agreement in local stress states with the measured values, a far field strain state was determined to the modified model in which material properties of upper granite and lower granite are different. In intermediate region modeling by FDM, actual strata data was taken into account, whereas strata boundary was assumed to be horizontal in former modeling, and far field stress field was analyzed. Intermediate region modeling by BEM was also carried out and far field stress state was determined. In wide region modeling by FEM, the fault was build in the model and fault slip was taken into account, and evaluation of strain state at the far field boundary was carried out for inhomogeneous rock including fault. It was proposed to output three-dimensional distribution of the maximum shear stress coefficients in order to advance three-dimensional modeling. It will make clear effect of shape, scale and property of the fault on stress state characteristic. This report describes minutely the results of the studies mentioned above. (author)

'Geoscientific' research at Tono are developing site investigation and assessment techniques in geological environment. One of their important themes is to establish rational methodology to reduce uncertainties associated with the understanding of geological environment, which often exhibits significant heterogeneity. Purpose of this study is to identify and evaluate uncertainties associated with the understanding of geological environment. Because it is useful to guide designing effective site investigation techniques to reduce the uncertainty. For this, a methodology of the uncertainty analysis concerning the heterogeneous geological environment has been developed. In this report the methodology has also been tested through an exercise attempted in Tono area to demonstrate its applicability. This report summarizes as follows: 1) The exercise shows that the methodology considered 'variability' and 'ignorance' can demonstrate its applicability at three-dimensional case. 2) The exercise shows that the methodology can identity and evaluate uncertainties concerning ground water flow associated with performance assessment. 3) Based on sensitivity analyses, it is possible for the methodology to support designs of the following stage investigations to reduce the uncertainties efficiently.

Impact of Nitrification on the Formation of N-Nitrosamines and Halogenated Disinfection Byproducts within Distribution System Storage Facilities.

Science.gov (United States)

Zeng, Teng; Mitch, William A

2016-03-15

Distribution system storage facilities are a critical, yet often overlooked, component of the urban water infrastructure. This study showed elevated concentrations of N-nitrosodimethylamine (NDMA), total N-nitrosamines (TONO), regulated trihalomethanes (THMs) and haloacetic acids (HAAs), 1,1-dichloropropanone (1,1-DCP), trichloroacetaldehyde (TCAL), haloacetonitriles (HANs), and haloacetamides (HAMs) in waters with ongoing nitrification as compared to non-nitrifying waters in storage facilities within five different chloraminated drinking water distribution systems. The concentrations of NDMA, TONO, HANs, and HAMs in the nitrifying waters further increased upon application of simulated distribution system chloramination. The addition of a nitrifying biofilm sample collected from a nitrifying facility to its non-nitrifying influent water led to increases in N-nitrosamine and halogenated DBP formation, suggesting the release of precursors from nitrifying biofilms. Periodic treatment of two nitrifying facilities with breakpoint chlorination (BPC) temporarily suppressed nitrification and reduced precursor levels for N-nitrosamines, HANs, and HAMs, as reflected by lower concentrations of these DBPs measured after re-establishment of a chloramine residual within the facilities than prior to the BPC treatment. However, BPC promoted the formation of halogenated DBPs while a free chlorine residual was maintained. Strategies that minimize application of free chlorine while preventing nitrification are needed to control DBP precursor release in storage facilities.

1997-03-01

Investigation for characterization of rock properties of the Excavation Disturbed Zone (EDZ) were carried out in NATM drift of North Extension in the Tono Mine. As a part of this investigation, hydraulic tests were performed by means of the hydraulic measuring instrument, which had been developed by PNC Tono Geoscience Center. The purpose of this tests is to characterize the change in hydraulic properties of the EDZ caused by drift excavation using machine (boom header). The hydraulic tests were performed in the burials MH-1,2,3, in which hydraulic tests had been performed before the drift excavation in 1994. The test results indicate that the measured values of pore water pressure have decreased after excavation of the drift. The values ranged from -0.037 kgf/cm 2 to 0.039 kgf/cm 2 . The measured hydraulic conductivities ranged from 2.2*10 -11 cm/s to 9.1*10 -11 cm/s for mud stone and from 2.8*10 -9 cm/s to 2.4*10 -7 cm/s for conglomerate. The measured hydraulic conductivities for mud stone are below the lower limit of the instrument, and the change in the hydraulic conductivities for conglomerate is little. The hydraulic conductivities for conglomerate and mad stone (reference values) are interpreted. The change in hydraulic conductivities measured before and after excavation of the drift is insignificant. (author)

Geochemical behaviour of natural uranium-series nuclides in geological formation

International Nuclear Information System (INIS)

Yamakawa, Minoru

1991-01-01

Recent research and investigation show that the Tono uranium deposit and its natural uranium-series nuclides have been preserved, without any significant changes like re-migration or reconcentration, throughout geological events such as upheaval-submergence, marine transgression-regression, and faulting which can readily change geological, hydrogeological, and geochemical conditions. This situation might have come about as a result of being kept in a geometrical closure system, with reducing and milk alkalic geochemical conditions, from the hydrogeological and geochemical point of view.

On the mining situation and future for Kibushi and Gairome clay in Tono-district. Tono chiku no kibushi nendo gairome nendo no sanjo to shorai ni tsuite

Energy Technology Data Exchange (ETDEWEB)

Omaru, I [Inagaki Clay Mining Co. Ltd., Gifu (Japan)

1993-07-10

The Kibushi clay and the Gairome clay which have been taking the role as the domestic produced bonding materials for refractories are running out. This paper reports their current situation and measures from the standpoint of producers. The Kibushi clay production has been decreasing since it has peaked in 1975 at 855,000 tons down to as low as its half at 400,000 tons in 1989. The Gairome clay production has also been decreased sharply from having been produced at 30 mines to 7 mines in Gifu Prefecture. The current situation is such that not only higher cost is incurred in removing gravel beds covering the clay bed, but also no gravel disposal areas can be procured, and no profitability can be assumed because of degradation in clay quality. On the other hand, demand as raw material for sanitary earthenwares and potteries has been increasing rapidly from 2,265,000 tons to 2,779,000 tons, hence import dependence of the material is rising. Positive activities as measures against the ore depletion include an establishment of a company jointly invested by five companies in 1991, which intends to develop the industry from a mining industry to a manufacturing industry by custom-blending and reforming various kinds of clays produced in different locations, including imports, to achieve stable supply. 1 tab.

Full Text Available La luz es un factor ambiental muy influyente en la calidad de vida y el rendimiento de las personas. Por esta razón es necesario crear e implementar tecnologías que ayuden a mantener ambientes sanos, en términos de iluminación, para los usuarios. Si a esto sumamos la gran cantidad de energía eléctrica que se desperdicia por malos hábitos de consumo y por el uso de dispositivos anticuados e ineficientes, resulta evidente la importancia del presente trabajo, el cual propone el diseño de una lámpara compacta y versátil que reemplace fácilmente a los focos tradicionales con ventajas como un control automático para el encendido y apagado en función del movimiento registrado en la habitación, un control automático de nivel de iluminación para mantener niveles óptimos en todo momento y regulación del tono de la luz de acuerdo a la habitación y a la hora del día. Para lograr lo anteriormente mencionado se utilizó tecnología LED, un microcontrolador y sensores que junto con técnicas de control gobiernan el comportamiento de la lámpara. Se establecieron varios parámetros de funcionamiento como nivel de iluminación y tono de la luz emitida los cuales se cumplieron dentro de ciertas condiciones operativas.

The developmental study made at Tono Geoscience Center under the Earthquake Frontier Research Project since 1996 is reported for a brand new technology system called ACROSS (Accurately Controlled, Routinely Operated, Signal System invented at Kagoya University in 1994). Various technology elements have been combined together under a specific theoretical framework for the underground exploration and monitoring of structures and physical states. The ACROSS is essentially a spectroscopy of the underground space consisted of complex media subjected to environmental noise. The robustness against noise is devised by utilizing coherent elastic and electromagnetic waves with phase controlled very accurately. Demanded hardware technology has been developed successfully and know how has been accumulated for practical applications. Accurate synchronization of transmission and observation systems has provided us with reliable data on the tensor transfer function between the source and receiver, which is equivalent to Green function within a limited frequency range. Several examples of the field application are demonstrated by the test experiments at Tono Mine site. After the developmental works of 10 years, the ACROSS is brought to be a practical method applied to the remote monitoring of temporal variation of underground states at the Horonobe Underground Research Laboratory and also it is being applied to the expected focal region of the coming Tokai earthquake near Hamaoka in Shizuoka prefecture. Whereas ACROSS technology is not mature enough yet, it is shown to be a potential and versatile methodology applied even for the health monitoring of the construction such as building strongly coupled with the ground in addition to the underground study.

Teores de carbono orgânico total foram superiores nas camadas superficiais no campo, quando comparados com a floresta. Dados de delta13C associados à cronologia do 14C indicaram predomínio de plantas C3 no início do Holoceno em ambos os ecótonos. Entre aproximadamente 7.000-3.000 anos AP verificou-se a influência crescente de plantas C4, indicando regressão da floresta com possível presença de um clima mais seco. A partir de aproximadamente 3.000 anos AP os dados sugeriram expansão da floresta provavelmente relacionada ao retorno a um clima mais úmido. A presença de algumas espécies características da borda, como a Sclerolobium paniculatum e Himatanthus sucuuba, nos campos, sugere o atual avanço da floresta sobre os mesmos. Estas espécies estariam sendo as bioindicadoras desse avanço.This paper presents a comparative study between organic soil horizons formed in depressions located at the forest/savanna boundary in the Southern Amazon Basin.

This paper presents the development and functionality of a suite of applications which are being developed to support the geological investigations in the Tono URL. GEOMASS will include 3D geological modelling, 3D fluid flow and solute transport and 3D visualisation capabilities. The 3D geological modelling in GEOMASS will be undertaken using a commercially available 3D geological modelling system, EarthVision. EarthVision provides 3D mapping, interpolation, analysis and well planning software. It is being used in the GEOMASS system to provide the geological framework (structure of the tectonic faults and stratigraphic and lithological contacts) to the 3D flow code. It is also being used to gather the geological data into a standard format for use throughout the investigation programme. The 3D flow solver to be used in GEOMASS is called Frac-Affinity. Frac-Affinity models the 3D geometry of the flow system as a hybrid medium, in which the rock contains both permeable, intact rock and fractures. Frac-Affinity also performs interpolation of heterogeneous rock mass property data using a fractal based approach and the generation of stochastic fracture networks. The code solves for transient flow over a user defined sub-region of the geological framework supplied by EarthVision. The results from Frac-Affinity are passed back to EarthVision so that the flow simulation can be visualized alongside the geological structure. This work-flow allows rapid assessment of the role of geological features in controlling flow. This paper will present the concepts and approach of GEOMASS and illustrate the practical application of GEOMASS using data from Tono

The Tono Research Institute of Earthquake Science (TRIES) has developed a multicomponent instrument that can be operated in deep boreholes (e.g., those one km in depth). It is equipped with stress meters, strain meters, tilt meters, seismometers, magnetometers, and thermometers; in addition, these sensors can be arbitrarily combined. The stress meters, which were developed recently, can observe stress and strain; in the future, data obtained from these sensors will offer new information on seismology and rock mechanics. The size of typical probe is 12 cm diameter 7.8 m total length and 290 kg total weight. It consists of many meters in tandem connection. (authors)

For artificial coalification, condensation reactions of aromatic ring and activated compounds produced by dehydrating reaction of glucose were studied experimentally. In heat treatment experiment in water, three reaction specimens such as glucose, glucose and phenol, and glucose and benzaldehyde were fed into an autoclave together with distilled water, and subjected to reaction at 180{degree}C under spontaneous pressure for 50 hours. In hydrogenation experiment, the specimens were fed into an autoclave together with tetradecane and sulfurization catalyst, and subjected to reaction at 350{degree}C under initial pressure of 9.8MPa for 2 hours for gas chromatography (GC) analysis of products. As the experimental result, the reaction between glucose and aromatic ring in heat treatment in water occurred between aromatic ring and active fragment with a mean carbon number of 4-5 produced by decomposition of glucose. The reactivity was higher in benzaldehyde addition than phenol addition. 3 refs., 4 figs., 1 tab.

Full Text Available This article is part of the research project, “Youth musical mediations,” that explores the appropriation of alternative means of communication which allow the young to develop identities sharply differentiated from those the adult world. In particular, the article examines the world of hip hop in Medellín and the ways that youth participate in it. To follow key trajectories of women in hip hop, their voices, feelings, and memories must be uncovered. This will allow us to see how the few women who are currently part of hip hop scene in Medellín and Colombia enter, move through, and persevere in it. Since women constitute only a small percentage of the youth who live and remake hip hop in Medellín, it is important to understand how they manage to live in a male-colored world. If hip hop is about strength, denunciation, confrontation, and resistance, it seems that these qualities are more appropriate for men than for women

To investigate the effects of the modulus of the lens material on the intraocular pressure measurement using the Tono-Pen XL applanation tonometer through soft contact lenses. Thirty eyes of 15 patients with myopia were evaluated. Intraocular pressure (IOP) measurements were performed using Tono-Pen XL directly over cornea, and subsequently through three soft contact lenses made up of different lens materials. All were -3.00 diopter soft contact lenses: lotrafilcon A with a low water content (24%) and high modulus (1.4 MPa) (CL-I), balafilcon A with a moderate water content (36%) and moderate modulus (1.1 MPa) (CL-II), and vifilcon A with a moderate water content (55%) and low modulus (0.79 MPa) (CL-III). IOP measurements through contact lenses were compared with each other, and with direct corneal measurements. The mean age of the patients (11 males and 4 females) was 26.86±5.62 years. All measurements obtained through CLs were significantly higher than the direct corneal measurements. The measurements through CLs differed by 4.61±0.54 mmHg (P=0,001), 2.9±0.46 mmHg (P=0.001), and 1.94±0.51 mmHg (P=0,003) for CL-I, CL-II and CL-III, respectively. In the paired comparisons of measurements through CLs, all comparisons were significant except the comparison of measurements through CL-II and CL-III (P=0.128). IOP measurements through silicone-hydrogel contact lenses with a high modulus and low water content were higher compared to the other contact lenses. While measuring IOP through CLs, the clinicians should consider the effect of the lens material and the features of the device used.

The concentrations of fluorine (7.2-10mg/L) and boron (0.8-1.5mg/L) dissolved in groundwater pumped from shafts during excavation at the Mizunami Underground Research Laboratory (MIU), Tono Geoscience Centre, must be reduced to the levels below the environmental standards (fluorine:0.8mg/L, boron:1mg/L). Coagulation treatment and ion exchange treatment are applied for fluorine and boron at a current water treatment facility in MIU, respectively. A collaborative research on groundwater treatment for fluorine and boron was started by the Environment and Industrial Materials Research Division, Quantum Beam Science Directorate and the Tono Geoscientific Research Unit, Geological Isolation Research and Development Directorate in 2006. This is because the Quantum Beam Science Directorate has synthesized fibrous adsorbents with radiation-induced graft polymerization and applied them to collect rare metals dissolved in hot springs and sea water. Boron adsorbent synthesized by grafting showed higher removal rate than that of the ion-exchange resin. Additionally, the durability and the repetitive use of the boron adsorbent were evaluated to estimate the capacity of the boron adsorption. Therefore we produced a test equipment to do scale-up test of the adsorbent. Effects of flow rate and the repetitive use on the adsorption capacity of boron were investigated. As a result, it concluded that the adsorption capacity of the boron adsorbent did not change even when the flow rate increased from SV 50h -1 to 100h -1 . In addition, enough durability was confirmed for the repetitive use of the adsorbent. The adsorption capacity of the adsorbent was affected by pH of the groundwater especially in high alkaline range above a pH of 10. (author)

Non-contact Tonopachy NT-530P (Nidek Co., LTD) provides intraocular pressure (IOP) and central corneal thickness (CCT) measurements. This study assesses the reliability and repeatability of its IOP measurements in young healthy adult subjects. IOP was determined in the right eye of 64 healthy patients using Tonopachy followed by the Canon TX-10 non-contact and Goldmann applanation (GAT) tonometers. Tonopachy IOP measurements were corrected (Tonopachy-C) or not (Tonopachy-NC) by the instrument for central corneal thickness. Central corneal thickness measurements provided by Tonopachy were also used to correlate (Pearson's coefficient) central corneal thickness with the GAT and Canon TX-10 IOPs. Repeatability of Tonopachy and GAT was assessed in the right eye of 31 subjects in two separate sessions one week apart. Differences between pairs of instruments and between sessions were determined using Bland-Altman plots. The coefficient of repeatability was calculated as the 95% limits of agreement (LoA) of differences between the two sessions. Tonopachy-NC, Tonopachy-C, Canon TX-10 and the Goldmann tonometers showed a mean IOP of 14.62, 15.64, 15.02 and 14.68 mmHg, respectively. Tonopachy-NC and Canon TX-10 readings did not differ significantly from the Goldmann (p > 0.05), with close agreement with both tonometers (GAT versus Tonopachy-NC: -3.84 to 3.96 mmHg; Goldmann versus Canon TX-10: -4.75 to 4.07 mmHg). Tonopachy-C readings differed significantly from Goldmann (mean difference -0.96 mmHg, p = 0.001, LoA from -5.09 to 3.17). Coefficients of repeatability were ± 3.70, ± 3.14 and ± 3.33 mmHg for GAT, Tonopachy-NC and Tonopachy-C, respectively. Central corneal thickness measured with Tonopachy was 530.42 ± 34.96 μm. There was a significant correlation between central corneal thickness and IOP for all tonometers except Tonopachy-C. Reasonable agreement was observed between the Goldmann and Tonopachy. This instrument provides reliable and repeatable IOP measurements not influenced by central corneal thickness. The Tonopachy-NC and Canon TX-10 offer similar reliability compared to the Goldmann applanation tonometer in a young normotensive population. © 2013 The Authors.

Arguyo que su redefinición valoriza la función de personajes femeninos que no sólo difieren físicamente de las ideas de belleza que se asocian con una diva sino que pertenecen a la clase trabajadora del país donde se desarrolla la acción. Por lo tanto, en estos cuentos se rinde tributo a otras formas de femineidad y de conocimientos que tienden a quedar excluidos por no ir a tono con las conductas y estéticas que afianzan el machismo.

Methods: All patients over the age of 18 years who underwent an LP in the emergency or neurological departments at the Tel Aviv Medical center for any reason between October 2007 and July 2010 were eligible to participate in this prospective observational pilot study. IOP was measured with the Tono-Pen XL while patients were in the supine position before undergoing LP. ICP was measured in the lateral recumbent position. ICP and bilateral IOP were measured, and the mean and maximum values of IOP were calculated. The association between ICP and each one of the four IOP measures was evaluated by the Pearson correlation coefficient. Results: Twenty-four patients (mean age 37.8 ± 15.8 years, ten males and 14 females were enrolled. The reasons for their requiring an LP were headache (19/24 patients, evaluation for hemiparesis (2/24, cognitive deterioration (1/24, and seizures (2/24. Nine had elevated mean opening pressure (>20 cm H2O, six had an elevated mean IOP (>20 mmHg, and four of these six also had an elevated opening pressure. There was no significant correlation between the ICP measurements and any of the IOP measurements. Conclusion: Handheld ocular tonometry has poor sensitivity and specificity for the prediction of increased ICP and is not an effective tool for screening for ICP in the ED or in the

The TGDc-01 "PRA" (Ryazan State Instrument, Ryazan, Russia) tonometer is a new portable small-sized tonometer that measures intraocular pressure (IOP) through the eyelid. The purpose of this study is to assess the repeatability of the TGDc-01 IOP measurements by comparing them against those obtained with Goldmann tonometer and with those from Perkins applanation tonometer, Xpert (Reichert, Depew, NY) noncontact tonometer, and Tono-Pen XL (Medtronic Solan, Jacksonville, FL) digital tonometer. Fifty-eight right eyes of 58 young subjects were measured with each of the tonometers. Noncontact tonometry was performed first, followed by Goldmann and Perkins applanation tonometer (in random order), digital Tono-Pen XL, and finally TGDc-01 tonometer (sitting and supine position). Correlation analysis was used to evaluate the relationship between the Goldmann tonometer and the remaining tonometers used in this study. Plotting the difference between the methods against mean was also done to compare the tonometers. The hypothesis of zero bias was examined by a paired t-test. The 95% limits of agreement (LoA) were also calculated. TGDc-01 showed no statistical difference between the IOP measurements obtained in sitting and supine positions. A poor relationship between the TGDc-01 and Goldmann tonometer was found (r = 0.173; p = 0.001). Although the mean differences between Goldmann and Tonopen XL, Xpert, and TGDc-01 IOP measurements were statistically significant, the wider 95% LoA was observed when comparing the Goldmann and TGDc-01 tonometers. Computation of the 95% LoA resulted in a wide bias range when comparing the TGDc-01 with all the tonometers used in this study. The TGDc-01 "PRA" tonometer was not comparable with the other techniques used in the study. The wide dispersion range of the values obtained shows low repeatability of the TGDc-01 for screening purposes. These results could be because of the technique of measurement and/or interindividual variables.

Topical atropine treatment is generally accepted to retard the progression of myopia, but it is associated with side effects such as photophobia and elevation of intraocular pressure (IOP). IOP measurements in children are challenging. The traditional applanation tonometry by direct contact with the cornea will require patient's cooperation. The rebound tonometer, using a dynamic electromechanical method for measuring IOP, shows good correlation with traditional tonometry. The purpose of this study is to evaluate the IOP of myopic children under atropine treatment using rebound tonometer and to compare the characteristics between rebound tonometry and applanation tonometry. This study is a prospective study measuring IOP by rebound tonometer in myopic children under regular low-dose atropine treatment. We recruited children with refraction error showing myopia over -0.5 D with 0.15%, 0.3%, or 0.5% atropine eye drops use every night or every other night for myopia control. Children with treatment duration of atropine tonometer (Tono-Pen XL, Reichert) and rebound tonometer (ICARE). The reliability of rebound tonometer was analyzed with percentage. Comparison of IOP between rebound tonometer and applanation tonometry was presented. The rebound tonometry was well tolerated by all participants and caused no complaints, discomfort, or adverse events. Totally 42 myopic eyes of 42 subjects were included in the study. The average age of these participants was 10 years old, range from 5 to 16. Median = 10 years old. The average IOP of the right eye by rebound tonometer was 17.4 ± 3 mmHg, and 17.1 ± 3 mmHg by applanation tonometry. Nearly 19%, 33%, and 24% of difference of IOP readings between rebound tonometer and Tono-Pen applanation are within 0 mmHg, 1 mmHg, and 1-2 mmHg, respectively. Rebound tonometry has good correlation with applanation tonometry and 76.1% of differences between two tonometers are <2 mmHg. The advantage of drop-free rebound tonometry has made it

The concentrations of fluorine (7.2-10mg/L) and boron (0.8-1.5mg/L) dissolved in groundwater pumped from the shafts during excavation of the Mizunami Underground Research Laboratory (MIU), Tono Geoscience Center, shall be reduced to levels below the environmental standards for fluorine: 0.8mg/L and boron: 1mg/L. Coagulation and ion exchange methods are being applied for fluorine and boron, respectively, at the operating water treatment facility at the MIU. As well, collaborative research on groundwater treatment started in 2006 between the Environmental and Industrial Materials Research Division, Quantum Beam Science Directorate and the Tono Geoscientific Research Unit, Geological Isolation Research and Development Directorate on a novel method to remove the fluorine and boron. The Quantum Beam Directorate has synthesized fibrous adsorbents with radiation-induced graft polymerization and applied the adsorbents to collect rare metals dissolved in hot springs and sea water. The results of previous testing indicated that the adsorbent was able to remove more than 95% of the boron and fluorine and that performance of adsorbent for boron removal was better than the performance using ion-exchange resin. It was also apparent that the pH of groundwater had an influence on the performance of the adsorbent with respect to boron removal. Therefore we reran the recycling tests using groundwater from the neutralization tank at the groundwater treatment facility were repeated. The results indicated that the performance of the adsorbent using neutral groundwater for boron removal was higher than using uncontrolled groundwater. However the bed volume (BV) with recycled adsorbent decreased compared to first use. It is thought that sulfur added at the groundwater treatment facility was retained by the adsorbent despite elution, and affected the performance such that repeat usage resulted in decreased efficiency. In addition, it is considered that the goals established in the first

Rock mass displacement measurements have been performed to understand rock mass behavior and its dependence on excavation method during drift excavation at the Tono mine. Rock mass displacements of 1.46 mm and 0.67 mm have been measured at one meter (0.33D: blasting, 0.42D: machine, D: width of drift) from the walls of drifts excavated by the drill and blasting method and machine, respectively. Numerical analysis of rock mass displacements with Finite Element Method has been performed assuming an excavation disturbed zone. Measured and analysed rock mass displacements are consistent with each other for the drift excavation by the drill and blasting method. The excavation disturbed zone was narrower for the drift excavated by machine than for the drift excavated by the drill and blasting method. (author)

Current status of regional hydrogeological studies on geological disposal including hydrogeological modeling using numerical simulators is reviewed in this report. A regional scale and boundary conditions of numerical models are summarized mainly from the results of the RHS (regional hydrogeological study) project conducted by Japan Nuclear Cycle Development Institute (JNC) in the Tono area. We also refer to the current conceptual modes of hydrology and numerical models of unsaturated zone flow at Yucca Mountain, Nevada, which is the arid site proposed for consideration as the United States' first underground high-level radioactive waste repository. Understanding behavior of a freshwater-saltwater transition zone seems to play a key role in the hydrogeological modeling in a coastal region. Technical features of a numerical simulator as a tool for geothermal reservoir modeling is also briefly described. (author)

Regional geologic settings of sandstone-type uranium deposits in Japan are firstly analyzed. The regional tectonic evolution characteristics of 'Green tuff region' and 'Non green tuff region' and their relationship with uranium mineralization are elaborated in depth. Based on those mentioned above, the uranium sources of sandstone-type uranium deposits in Japan are discussed deeply and the most favorable uranium sources are considered to come from the basement and the surrounding granites. Their intrusive epochs range from Later Cretaceous to Palaeogene (about 60 to 70 Ma ago). The characteristics of ore-bearing host rocks, matter compositions of the deposits, ore formation enrichment factors, the hydrogeologic conditions and so on are described by taking Ningyo-Toge and Tono deposits as examples. Finally, the prospecting measures for the palaeo-channel sandstone-type uranium deposits (basal type) are reviewed. (authors)

With an objective to elucidate relationship between human functions related to gravity in space and the gravity, simultaneous measurement was carried out on impulsive eyeball motions and antigravity muscles. The measurement used a non-polarized electrode mounted on a prescribed position on skin. The subject is a spacecraft crew who was subjected to an experiment in space in 1992. Data obtained during the flight were analyzed, and the following findings were obtained: the eyeball motions are performed accurately in terms of space and time; potential time relative to the target appearance time showed greater variation than in control conditions on the ground; activities of trapezius muscle as an antigravity muscle were suppressed, and electric discharge from the muscle was small even if the head is moved; the eyeballs move in coordination with the head when viewing an object; microgravity environment showed a head motion with very little muscle discharge possible as in the case where the head is held unmoved; and difference in motion patterns between the antigravity muscles and non-antigravity muscles may exist as a possible cause of spacesickness in addition to the conventional sensory disagreement theory. 32 refs., 6 figs.

This paper describes a study of a security method of protecting inside network computers against outside miscreants and unwelcome visitors and a control method when these computers are connected with the Internet. In the present Internet, a method to encipher all data cannot be used, so that it is necessary to utilize PEM (Privacy Enhanced Mail) capable of the encipherment and conversion of secret information. For preventing miscreant access by eavesdropping password, one-time password is effective. The most cost-effective method is a firewall system. This system lies between the outside and inside network. By limiting computers that directly communicate with the Internet, control is centralized and inside network Security is protected. If the security of firewall systems is strictly controlled under correct setting, security within the network can be secured even in open networks such as the Internet. 35 refs., 3 figs.

Let x = (x{sub 1}....,x{sub q}), R{sub q}(x) be the q-dimensional space (q{>=}2), s be the unit vector, and #Greek Capital Letter Omega With Tonos# the surface of the unit sphere. The problem of solving transport equations with a degenerate scattering indicatrix is a multidimensional problem in R{sub q}x#Greek Capital Letter Omega With Tonos#; the nature of these problems calls for rapidly converging iterative methods which do not require all the information on the preceding step. The paper proposes a KP method: the idea consists in solving in R{sub q} simplified problems of error determination using successive iterative steps of decreasing difficulty. Two operations are performed in the KP: the K-operation is a simple iteration in R{sub q}x{Omega} and operation P = {l_brace}P{sub 1}(n{sub 1}),...P{sub 0}(n{sub 0}){r_brace} is for the error with P{sub k} (n{sub k}) representing the solution in R{sub q} of the ultimate problem for a differential equation of order 2n{sub k}. P-operations are found and the convergence of the following methods is studied: KP{sub 1}(n), P{sub 2}(0), K{sup 2}P{sub 1}(n), cyclic KP{sub 1}(1) and KP{sub 1}(0) etc. For 2{pi}T periodic problems the convergence is estimated, P(KP) (KP price) and cheap algorithms are found, and the non-improvability is shown. Numerical calculations indicated that the KP method is very efficient. The Case results are generalized for the q-dimensional case: in Rqx{Omega} a system of solutions is found for a homogeneous single-velocity transport equation with constant coefficients and an isotropic scattering indicatrix {Phi}{sub {omega}}(S)exp({+-}(x, {omega})/v) These are generalized functions with {sub v}#Greek Lunate Epsilon Symbol#{l_brace}(-1, 1], {+-} v{sub 0}{r_brace} and {omega} #Greek Lunate Epsilon Symbol#.

Test of the use of a measurement technique for the hydraulic conductivity of geological structures which act as flow paths or are impermeable to groundwater flow. In order to prove the value of flow-meter logging as an in-situ technique for detecting conductive fractures in granitic rocks, the method has been applied to a borehole near the Tono uranium mine, Gifu, Japan. This study in involved with detecting a conductive fracture and calculating the hydraulic conductivities. The results were as follows: (1) In a zone of groundwater inflow into the borehole, the hydraulic conductivity was calculated to be of the order of the 10 -3 - 10 -4 (cm/sec) from flow-meter logging. This value agreed with the results of a in-situ borehole permeability test carried out with a similar depth interval. (2) The study showed that flow-meter logging is effective for detecting the distribution of high conductivity fractures and calculating the hydraulic conductivity. (author)

Full Text Available Frente a las limitaciones ideológicas y políticas del régimen isabelino surgió en 1868 un relanzamiento político promovido a través de una coalición compuesta de unionistas, progresistas y demócratas en torno a un programa que tenía como puntos fundamentales el derrocamiento de la monarquía de Isabel II y el planteamiento de un nuevo sistema sustantado en la soberanía nacional y que tendría que ser definido en unas Cortes Constituyentes elegidas por sufragio universal. Se partía así de unas perspectivas liberalizadoras y éstas terminaron por asentarse a través de ios programas de las juntas revolucionarias y de la presión popular que incorporaron toda una serie de reivindicaciones de libertades y derechos de los ciudadanos imponiéndose el tono democrático típico del movimiento revolucionario de 1868.

La ética como imprescindible ficción antropológica

Full Text Available [ES] Hablar de ética, como de cualquier otra cosa, es tratar de la vida humana desde una mirada obviamente finita y eso aconseja cierta humildad en el tono y asumir el carácter provisional de las afirmaciones. Se trata de un discurso contingente, aunque no se reconozca, como la propia peripecia atribulada de los hombres, donde las mayúsculas y los absolutos son inadecuados porque menosprecian la menuda realidad de los hechos y conducen al choque sectario. [EN] To speak of Ethics, as of anything else, is to deal with human life from an obviously finite look, and that advises certain humility in tone and to assume the provisional nature of the statements. This is a contingent speech, although it may not be recognized, as the troubled vicissitudes of men, where capital letters and absolutes are inadequate because they disparage the minute reality of facts and lead to sectarian clash.

Cuando Verena Stolcke y poco después Aurelio Díaz me invitaron a participar en este acto de homenaje y memoria a Ramón Valdés del Toro pensé, en primer lugar,que prepararía algo sobre el papel de Ramón en los inicios de la Antropología española.Comencé a escribirlo pero resultaba un texto demasiado erudito, aburrido y difícil de digerir. En esta situación de stand by agradecí un correo electrónico de Verena en el que se nos instaba a “intervenir a vuestro aire en torno a vuestros recuerdos personales del magisterio y de la obra de Ramón”.

Abstract: This article sets out to explore the ways native speakers as well as foreign language learners use dictionaries and the strategies dictionary users adopt in the language acquisition process. The basis for this article is a corpus of six books (in chronological order Atkins (Ed. 1998, Nesi 2000, Tono 2001, Humbl? 2001, Sin-wai (Ed. 2004 and Thumb 2004 that look at both the usage of bilingual, monolingual and bilingualised dictionaries and the users' behaviour in the consultation process. Both the bilingual and monolingual dictionaries seem to be used independently, depending on whether the user wants to utilise them for comprehension, translation or production with regard to a foreign language. As pointed out in the literature on lexicography, some of these dictionaries, though they have undergone many changes over the years, still have serious limitations as learning tools, but the user's performance is also under investigation in empirical research, with the aim of optimising dictionary effectiveness as well as developing the language learner's skills.

La atrofia urogonital causada por el estímulo deficiente estrogenito se manifiesta principalmente en la vagina, donde la mucosa sufre un adelgazamiento gradual que permite el predominio de células parabasales e intermedias propias del hipoestrogenismo, volviéndolo altamente sensible al trauma y la infección.

Clínicamente se traduce en disminución de la humedad vaginal, sensación de llenura en el intróito, ruptura fácil de capilares vaginales con aparición de petequias, irritación, prurito y dispareunia.

A nivel del endometrio se pueden presentar uno de los siguientes cambios: proliferación débil, atrofia senil, hiperplasia quística, hiperplasia adenomatosa, neoplasia omás raramente trastorno secretor; cambios que corresponden clínicamente a intervalos oligomenorreicos interpuestos por episodios hemorrágicos que finalmente terminan en amenorrea definitiva. En casos de sangrados postoriores ameritaría estudios anatomopatológicos de control obtenidos por biopsia o legrado uterino. Otros cambios que se presentan en el útero incluyen la pérdida de tono en sus ligamentos y elementos de sostén así comola disminución del cuello y su secreción.

A nivel urinario la pérdida del tono uretral cursará con prolapso de la mucosa a través del meato, uretritis ahacteriana recurrente manifestada por poliaquiuria, disuria de ardor e incluso incontinencia urinaria de esfuerzo.

Los cambios descritos anteriormente, hacen que la sexualidad femenina sea perturbada al presentarse dispareunia, disminuyendo de ritmo sexual y libido de la mujer haciendo su vida de pareja difícil y caótica. Se ha descrito también que la disminución de estrógenos produce ansiedad, depresión, tensión e irritabilidad al no permitir la disociación del triptófano de la albúmina para así formar sustancias tales como la hidroxitriptamina que participa en el mejoramiento del estado de ánimo. Esta etapa será de adaptación difícil y

With this scenario, t his study aimed to carry out a floristic inventory of a forest fragment on ecological tension in Bodoquena Plateau, MS, Brazil, and assess their phytogeographical relationships with other surveys of seasonal forests and savannas in the Midwest and Southeast regions of Brazil. For this, 102 contiguous plots of 10x10 m (100 m 2 were sampled. The inclusion criterion was the perimeter at breast height (PBH ≥ 15 cm. For floristic similarity analysis, the coefficient of Sorensen was applied, adopting the unweighted pair group method with arithmetic mean (UPGMA, with the determination of the level of similarity of 26 floristic lists. Of the 96 species occurring in this survey, 91 were identified at species level, and of these, 80.2% (73 were found in one or more studies of the analyzed areas with higher occurrence in seasonal deciduous forest (SDF (54, followed by seasonal semideciduous forest (SSF (47 and forested savannah (46. The results showed clustering of the study area with the FED of Minas Gerais in level of 30%, revealing low similarity. Due to low floristic similarity between the analyzed areas, these are characterized by their high beta diversity.

The distribution of the change in groundwater volume at the site of Mizunami Underground Research Laboratory in the Tono area, Japan, was estimated by the inverse method proposed by the authors, using tilt data measured with four tiltmeters at the surface during drainage, submergence and re-drainage in excavation of shafts. Furthermore, the reliability of the results was evaluated by a model analysis for groundwater flow in a single ellipsoidal field. The results showed that the hydrogeological structure for the region of 1000 m x 1000 m in area and 100 m to 180 m in depth is such that groundwater flow occurs mainly in a region between two impermeable faults with the center at 100 m to 150 m south of the Main shaft and this region tends to shrink toward north-west and be widened toward south to south-east. However, at the same time, the model analysis showed that areas north-west and south-east of the Main shaft in the corners of the region are vacua for estimation due to the aligned layout of the tiltmeters.

Di lui veniamo a sapere tutto ciò che occorre per accostarsi alle teorie che gli valsero il premio Nobel, ma anche i tratti di una normale vita borghese nella quale si intrecciavano le influenze dell'ambiente intellettuale e commerciale. Il tono è quello di una rievocazione piana e distesa che ci accompagna per le varie fasi della carriera dello studente, del docente, dello scienziato, nelle università tedesche e inglesi, negli anni delle persecuzioni naziste, alle quali l'ebreo Max Born ebbe la fortuna di sopravvivere, e nel dopoguerra, quando egli tornò in Germania e seppe dare un contributo di idee e di iniziative ai movimenti pacifisti.

2002-01-01

'Natural analogues' can be defined as the processes or materials analogous to those operating in the geological disposal system of radioactive waste. Natural analogue studies provide the only means by which long-term data can be obtained under the real natural conditions, and also the most convincing support to the long-term performance assessment of the geological disposal system. The framework of our natural analogue studies concerning the stability of the engineered barrier materials for geological disposal system of high-level radioactive waste is reviewed. One of the results is that the volcanic glass included in a clay bed did not alter during the past one million years. The Tono Uranium Deposits are studied as geochemical analogues of radioactive waste disposal in Japan. We conclude that although the deposits have been subjected to a variety of geological processes and events such as faulting, erosion and uplift/subsidence, the reducing condition has been maintained and uranium has not migrated for at least the past ten million years. Application and further development of the natural analogue studies are also discussed. (author)

Full Text Available Il mito letterario di don Giovanni, sorto nella commedia, attorno al 1800 viene riformulato in direzione del tragico. La trasformazione inizia con la versione operistica di Mozart-Da Ponte e trova compimento nel racconto di Hoffmann, che proietta il nuovo tono tragico del finale mozartiano su tutto il mito. L’articolo intende porre in rilievo la presenza nel Don Juan di numerosi richiami intertestuali al Faust di Goethe, finora non pienamente rilevati dalla critica, attraverso i quali è possibile leggere tale riscrittura tragica come una dichiarata sintesi dei due miti, in cui don Giovanni assume il ruolo di Faust-Mefistofele e donna Anna quello di Gretchen. La riscrittura del mito culmina nel finale rispecchiamento del narratore in Anna-Gretchen. Ma il valore del tragico è relativizzato in Hoffmann dall’ironica autocoscienza dell’artista romantico: confinato nel mondo fantastico dell’arte, risulta privo di senso nella prosaica realtà della vita borghese.

In the Tono Geoscience Center of Japan Atomic Energy Agency (hereafter, JAEA), Mizunami Underground Research Laboratory project is being advanced to develop a scientific and technological basis for geological disposal. The concept of geological disposal is based on a multi-barrier system which combines a stable geological environment with an engineered barrier system (EBS). In order to develop a engineering basis for the construction of disposal system, the enhancement of grouting technologies among engineering technologies is needed. In this study, the comprehensive performance of suspension type grouting materials to seal rock fractures encountered in excavation works at deep underground has been checked, and the clogging phenomenon at the entrance of rock fractures has been investigated following the previous year. Research issues are as follows; Study on grouting concept to secure high-level water sealing, study on the test method to check grout clogging under high injection pressure, study on grouting material which can penetrate into finer fractures. Among these, in the study on penetrability test method, prototype test instruments were made and a series of preliminary tests were conducted. (author)

In order to clarify a humification process in the early stage of coalification, the nitrogen functionality of prepared glucose-glycine condensate was studied experimentally. In experiment, the condensate was prepared by heating the mixture of glucose, glycine and water in a autoclave at 130{degree}C for 50 hours, and furthermore heating the produced solid material in water at 300{degree}C. After the condensate was hydrocracked, the fraction, condensate and hydrocracking residue were analyzed by elementary analyzer, {sup 13}C-NMR, XPS, FT-IR, capillary GC-FID/NPD and GC-MS. As a result, the glucose-glycine condensate could be arranged on the basis of three types of nitrogen such as pyridine, pyrrole and quaternary amine type. Pyridine type nitrogen increased, while quaternary amine type one decreased with an increase in heating treatment temperature. Rich pyrrole type nitrogen and poor pyridine type one were found in light nitrogen compounds in hydrocracked products. 2 refs., 4 figs., 2 tabs.

En P. mollissima cultivada en espaldera se observa que el crecimiento es acrótono. Las podas hacen más notable la acrotonía.3. EI transcurso de la cosecha depende del transcurso de la floración y de condiciones climáticas; por eso las cosechas de las ramas laterales de primer y de segundo orden pueden ser separadas o no.4. En descendencias de P. mollissima autopolinizada se presentan segregaciones en cuanto a distintas características, entre ellas también con respecto al habito de crecimiento.5. Con base en las observaciones se desarrolla un sistema de poda de renovación. Esta poda no influye sobre el transcurso de la cosecha, pero rebaja algo el vigor de la planta. Resultados definitivos sobre el valor de la poda sólo se pueden obtener mediante observaciones de varios años.

Full Text Available De acuerdo con la estilística y la crítica literarias, Cien Anos de Soledad de Gabriel García Márquez, se caracteriza por aludir constantemente a los personajes de la historia y narrar los eventos en tono neutro. En este artículo se utilizan métodos estilométricos para ratificar dichas afirmaciones y proveer nuevas visiones sobre la novela. Estos métodos incluyen, entre otros, el conteo de palabras y de frases, la construcción de árboles de consenso, el cálculo de la polaridad de las oraciones, e índices para cuantificar la complejidad y el nivel de concreción del texto. Los resultados indican la tendencia del autor a emplear, frecuentemente, palabras abstractas y referentes a objetos con los que se puede interactuar físicamente, para producir el efecto lingüístico propio del realismo mágico. Dada la importancia de los hallazgos, se plantean algunas ideas acerca de las implicaciones que la metodología puede tener en áreas de la psicolingüística y de la psicología cognitiva.

En el marco de la campaña sanitaria contra la mortalidad infantil que puso en marcha la Segunda República en la década del 30, la Asociación Española de Médicos Puericultores Titulados, en colaboración con Unión Radio, organizó dos ciclos de conferencias radiofónicas que pretendían explicar, a través de un discurso divulgativo de tono descriptivo dirigido a las clases populares, las nociones fundamentales de la higiene y la alimentación infantil, e impulsar una cultura de la prevención, guiada y orientada por los dictados de los expertos. Se trataba de una acción de propaganda y divulgación que tenía su continuidad en el medio familiar y comunitario a través de la actuación de las enfermeras visitadoras puericultoras, contemplando a las madres como población diana.

Dado que Cuba es uno de los países considerados distinguidores de caso, resulta especialmente interesante conocer qué verbos y qué estructuras pronominalizan en ambos casos o se inclinan por el uso del dativo en lugar del acusativo, con el fin de analizar las posibles opciones y determinar qué estructuras o tipos de verbo determinan y condicionan la elección del pronombre. Para ello, abordaremos el uso de los clíticos de tercera persona en verbos o construcciones transitivas y de caso reinterpretado, así como otros fenómenos interesantes como la inmovilización del pronombre le y la duplicación del complemento mediante clítico.

The effects of earthquakes and active faults on the geological environment have been studied at the Tono Geoscience Center. The Hyogoken-Nanbu earthquake (January 17, 1995; M7.2) in Kobe and Awaji island caused significant changes in hydrology, involving a large amount of groundwater discharge in low-lying land and drastic water-table lowering (during only about 2-4 months) in elevated land near the epicenter. Simulation of the groundwater behavior in the vicinity of the Nojima fault was analysed to evaluate permeability enhancements. Calculated values such as water level changes were matched in a time series with the hydrological observed data in order to optimize this simulation model. Results indicate that the increase of hydraulic conductivity (5 x 10{sup -3} cm/s in weathered granitic rocks) and 1 x 10{sup -5} cm/s in fresh granitic rocks would produce a lowering of the water level at EL 180 m, and increase of discharge at less than EL 100 m, within four months after the earthquake. The study also suggested that the change in the hydraulic conductivity in the Nojima fault could not depend on the change in geological hydrology. (author)

Los libros que de ellos tratan, ante todo los que 10 hacen en tono crítico, baten records en la industria editorial en todo el mundo. Las expectativas que acerca del futuro abrigan cientos de millones de personas se relacionan con 10 que ellas esperan, para bien o para mal, de la globalización. Las posturas que los gobernantes ocupan al respecto en el mundo son, cuando menos de aceptación, generalmente de activa participación en pos de la globalización. Por un lado, crece la preocupación y se multiplican las protestas; por el otro, dominan los razonamientos de los especialistas en materia de maximización de los rendimientos de los capitales que presentan la globalización, al estilo que se viene imponiendo, como el camino ineludible del gobierno universal de la eficiencia. ¿Tienen que decir algo los historiadores frente a todo esto?.

Full Text Available La última obra de Bartolomeu Campos de Queirós, la novela Vermelho Amargo (2011 es notable por su forma y contenido. La portada de la primera edición hecha por Cosac Naify, de color rojo oscuro y sin la vida que caracteriza a los tonos púrpura, anuncia el contenido doloroso de la narración, que es una mezcla de memorias en prosa poética y de escritura autobiográfica. Las imágenes de la infancia se abren como heridas mal curadas, y el lector tiene la oportunidad de desvelar el poder del verbo poético cuando se enfrenta directamente a estas llagas. En el presente artículo nos proponemos analizar la escritura autobiográfica y la memoria narrativa, con el fin de poner de relieve la imagen de la casa como construcción de la conciencia. Estos temas tienen el apoyo teórico de Gaston Bachelard especialmente en sus reflexiones sobre la poética del espacio relacionada con la primera casa, considerado lugar de formación de las subjetividades del ser.

De hecho, aun cuando el entrevistado se arrepienta de su paso por la militancia, tiende a exaltar su actividad y sus consideraciones en lo que entienden como su momento de “protagonismo histórico”. A partir del los testimonios en el archivo del Programa de Historia Oral de la Universidad de Buenos Aires, esta ponencia intenta una aproximación al análisis de la relación entre memoria, recuerdo y identidad del entrevistados que militaron entre 1955 y 1976. Así, la ponencia se centrará en dos temas interrelacionados. Primero, la narrativa de los entrevistados en cuanto al tono y al lenguaje, considerando en particular la construcción de imágenes determinadas. Y segundo, la memoria y el mito en la construcción de una historia personal como prisma para ver una historia sociopolítica.

The Mizunami Underground Research Laboratory (MIU) project is being carried out by Japan Atomic Energy Agency in the Cretaceous Toki granite in the Tono area, central Japan. The MIU project is a purpose-built generic underground research laboratory project that is planned for a broad scientific study of the deep geological environment as a basis of research and development for geological disposal of nuclear wastes. One of the main goals of the MIU project is to establish comprehensive techniques for investigation, analysis, and assessment of the deep geological environment. The MIU project has three overlapping phases: Surface-based Investigation (Phase I), Construction (Phase II) and Operation (Phase III). Hydrogeological investigations using a stepwise process in Phase I have been carried out in order to obtain information on important properties such as, location of water conducting features, hydraulic conductivity and so on. Hydrogeological modeling and groundwater flow simulations in Phase I have been carried out in order to synthesize these investigation results, to evaluate the uncertainty of the hydrogeological model and to identify the main issues for further investigations. Using the stepwise hydrogeological characterization approach and combining the investigation with modeling and simulation, understanding of the hydrogeological environment has been progressively improved.

Modalities of Tonometry and their Accuracy with Respect to Corneal Thickness and Irregularities

De Moraes, Carlos Gustavo V.; Prata, Tiago S.; Liebmann, Jeffrey; Ritch, Robert

2010-01-01

Recent advances in tonometry have led to the development of a number of devices with differing clinical applications. Their role in cases of abnormal corneal thickness and surface irregularities is particularly important, as inaccurate estimation of the true intraocular pressure (IOP) in such cases may lead to suboptimal evaluation. The purpose of the present review was to evaluate the accuracy of the most widely used devices in cases of corneal thickness and surface irregularities, based on a survey of the published literature. The analysis was based on a Medline search focusing mainly on papers that have evaluated the devices’ accuracy with respect to corneal thickness and irregularities. Nine device types (Goldmann tonometer, Tono-Pen, Perkins tonometer, Ocular Response Analyzer, non-contact tonometer, pneumatonometer, I-Care rebound tonometer, Pascal dynamic contour tonometer (DCT) and Phosphene tonometer) were described in detail. Moreover, the physical principles and major utility of each tonometer were compared. Each of the many different commercially available tonometers has specific advantages and disadvantages. New non-invasive technologies are getting closer to a precise estimation of the true IOP. However, among all tonometers, none is highly accurate when both corneal thickness and surface irregularities are present. Fifty years after its development, Goldmann tonometry remains the gold standard to which all other devices are compared.

Industrias Bachoco: estrategias de localización y competitividad ante el nuevo escenario avícola

Full Text Available Los cambios sustantivos en el sistema agroalimentario mexicano han impulsado a las empresas a aplicar estrategias que les permitan funcionar en un contexto cada vez más competitivo, complejo e incierto. En el ramo avícola, Industrias Bachoco ha logrado posicionarse como líder nacional, a pesar de las presiones de la apertura comercial y de la competencia interna de dos de los mayores consorcios avícolas transnacionales. El presente artículo destaca los resultados obtenidos por esta empresa a partir de su estrategia de desplazamiento por la república mexicana. Desde la perspectiva de la teoría de la localización y de la nueva geografía económica, se plantea la hipótesis de que tal estrategia le ha permitido a Bachoco sumar ventajas comparativas regionales y le ha conferido la capacidad de suministrar una oferta adaptada a las costumbres y tradiciones de cada mercado regional, que no ha sido igualada por ninguna de sus competidoras. Se concluye que la apertura total inminente del mercado avícola mexicano inducirá al consorcio a acelerar su actualización, para estar a tono y competir con las empresas internacionales.

Full Text Available Este trabajo analiza el objeto cibersexo partindo del contexto discursivo que involucró el concepto. Para este propósito, partimos del cuestionamiento de su especificidad mediante el análisis de las definiciones actuales en el ámbito científico. Después, trazamos la arqueología de su aparición en el campo del conocimiento, basado en un levantamiento del discurso transmitido por los medios de comunicación y revistas científicas, en tres momentos diferentes. En un primer momento, se analiza su emergencia como un problema de identidad que luego toma un tono peligroso marcado por el discurso de los medios de comunicación. Entonces vemos cómo el cibersexo comienza a ser conjurado por la dimensión jurídica a través de la sospecha permanente de crimen potencial. Finalmente, se investiga su inclusión en el ámbito de la Psicología, principalmente a través de discursos de patologización. Llegamos a la conclusión de que el concepto de cibersexo no se limita a este marco epistemológico que no contempla las experiencias únicas que revelan su dimensión molecular.

Full Text Available En diálogo con las fuentes griegas de la Antología Palatina de la colección de Cambridge se analiza el tema cultural de mesura-desmesura en el género epi- gramático cuyo valor testimonial de quince o dieciséis siglos de literatura griega sorprende. Se trata de un cuerpo de poesías de variada inspiración y de autores datados entre el VII a.C. y el VII d. C., conocidos y anónimos y en mayoría pagana. Llama la atención el campo casi inexplorado de un género que refleja el modo de pensar y sentir griego así como la falta de una traducción castellana que acerque la lectura de estas pequeñas obras de arte, más o menos ignotas, a un público lector más amplio. Entre la variedad de epigramas, se pretende seleccionar y analizar un corpus de poemas protrépticos que en tono dialógico aconsejaban, amonestaban a conquistar la excelencia, el orden y la reflexión en el comportamiento y costumbres humanas, válidas para el hombre de todas las épocas.

Tono Geoscience Center of Japan Atomic Energy Agency (JAEA) has been carrying out the Mizunami Underground Research Laboratory (MIU) Project, which is a scientific study understanding the deep geological environment as a basis of research and development for geological disposal of high level radioactive wastes. The aim of the MIU project is to establish comprehensive techniques for the investigation, analysis and assessment of the deep geological environment in fractured crystalline rock, and to develop a range of engineering techniques for deep underground application. This project has three overlapping phases: Surface-based investigation phase (Phase I), Construction phase (Phase II), and Operation phase (Phase III). Currently, the project is being carried out under the Phase III. Mass transport study is mainly performed as part of Phase III project. In Phase III, the goal of mass transport study is to obtain a better understanding of mass transport phenomena in the geological environment as well as to develop technologies for measurement of the mass transport parameters, model construction, numerical analysis and validation of those technologies. This study was planned to understand the influence of the geological characteristics of fracture on the mass transport parameters. This report presents the results of diffusion experiment, observation of polished thin section, sorption experiment and porophysicality measurement. (author)

Hydrological characteristics of Japanese rock

Ijiri, Yuji; Sawada, Atsushi; Akahori, Kuniaki

1999-11-01

It is crucial to evaluate the hydrogeological characteristics of rock in Japan in order to assess the performance of geosphere. This report summarizes the hydrogeological characteristics of various rock types obtained from broad literature surveys and the fields experiments at the Kamaishi mine in northern Japan and at the Tono mine in central Japan. It is found that the hydraulic conductivity of rock mass ranges from 10 -9 m/s to 10 -8 m/s, whereas the hydraulic conductivity of fault zone ranges from 10 -9 m/s to 10 -3 m/s. It is also found that the hydraulic conductivity tends to decrease with depth. Therefore, the hydraulic conductivity of rock mass at the depth of a repository will be smaller than above values. From the investigations at outcrops and galleries throughout the country, fractures are observed as potential pathways in all rock types. All kinds of crystalline rocks and pre-Neogene sedimentary rocks are classified as fractured media where fracture flow is dominant. Among these rocks, granitic rock is considered the archetype fractured media. On the other hand, andesite, tuff and Neogene sedimentary rocks are considered as intermediate between fractured media and porous media where flow in fractures as well as in rock matrix are significant.

Full Text Available The aim of this paper is to analyse the linguistic factors constraining the use of personal clitics lo(s, la(s, le(s in XVth Century Middle-Age Castilian, as revealed in the Relación de los Hechos de Don Miguel Lucas de Iranzo (1458. A multivariate analysis of data from this text shows that internal (morphological, syntactic, lexical and textual factors interact and allows us to imagine the simplest and original context where leísmo could start. A nearly categorical tendency to employ le for male referents as direct objects is developed with human antecedents and where Latin used dative case or alternated between dative and accusative case. If Latin used accusative case, occurrence of le (leísmo depends on a set of linguistic constraints whose effect is systematic and predictable, as shows a logistic regression analysis carried out in this paper. Use of le (leísmo for human antecedents is constrained by the following internal factors: etymology, the number and the clitic's position within the sentence, type of syntactic structure and the verb's tense.

On the insert reinforcing bar structure for the connecting part of the main tower of cable stayed bridges, this paper reports verification results on a load resistant safety with a full-scale model, structure analysis and construction work. The basic structure was composed of a drilled steel shell, inserted reinforcing bars, fixing structure of bars in lining concrete of the shell and a pressure bearing plate. As an experimental result, the connecting part had a sufficient load carrying capacity against both tensile and compressive loads. The shear stress of the insert reinforcing bar structure was estimated successfully under von Mises`s condition. The shear spring constant in deformation characteristics was linearly proportional to an inserted reinforcing bar ratio. In earthquake, nearly 60% of an allowable compressive load was transferred to concrete through the pressure bearing plate. The analytical results of load resistant deformation characteristics of the connecting part well agreed with experimental ones, and the proposed analytical model was applicable to estimation of a dynamic behavior. 5 refs., 22 figs., 4 tabs.

The purposes of this research are to establish large-scale reforestation techniques, and to transfer these techniques into Indonesia for contributing to the preservation of tropical rain forests and the protection of global warming. Lauan trees provide disease and drying resistance properties by inoculating their roots with mycorrhizal fungi, to promote their growth. This is due to the symbiotic relationship between them, in which mycelia of mycorrhizal fungi collect and bring water and nutritive substances in the soil to the roots of lauan trees and intake sugars from the roots as nutrition. Since lauan trees are local variety, they are suitable for the preservation of biosystem. Since their growth life is long, they are suitable for the fixation of CO2. However, the reforestation techniques have not yet been established. Between FY 1992 and 1997, a high survival rate about 60% was obtained through a method in which natural seedlings in mountains were implanted and a method in which seeds were planted in the nursery. About 34000 lauan trees have been planted for the reforestation tests. An inoculation method was established for the accelerated growth of seedlings with mycorrhizal fungi. Through the inoculation, the growth rate was increased up to three times of that without inoculation. The lauan trees grew up to 5 m, and the survival rate was also increased up to twice. 11 figs., 3 tabs.

The PNC/H-3 is the first progress report on the research and development of HLW geological disposal in Japan. This paper describes on overview of the performance assessment studies in the H-3 report and critical issues identified through the studies. Subsequently, the outline of the PNC's study plan for the post H-3 stage is introduced. The generic performance assessment studies in the H-3 report indicated that the performance of a massive engineered barrier system could be sufficient within a range of likely geological conditions in Japan. Sensitivity studies of the performance of the natural barrier system coupled with the strong engineered barrier indicated the importance of the investigation of geological barrier effects in the near-field. Studies in the H-3 indicated that the research approach which placed an emphasis on the near-field analyses was promising to confirm the technical feasibility of the HLW geologic disposal concept in Japan. In order to make the approach more promising and effective it is important to promote more detailed and comprehensive analyses of the near-field processes. The PNC's research and development of post H-3 stage before the year 2000 is focused on the detailed analyses of the near-field. A set of engineering scale laboratory experiments and in situ experiments at Tono and Kamaishi mines will play an important role for the post H-3 studies

Water permeability in granite is estimated by performing geophysical investigation using a 500m-deep test hole drilled in granitic rocks in the vicinity of a Tono mine. The investigation consists of flowmeter logging and geophysical logging. In flowmeter logging, a probe is moved up and down in the hole at a constant speed by use of a cable, and the cable speed and impeller revolution are used to workout the relative speed of the fluid in the hole. In the geophysical logging, a probe attached to the leading end of a logging cable is replaced with other probes so as to acquire different geophysical data. In a hole drilled in a crack-abundant rockbed such as a granitic rockbed, the inflow and outflow of ground water is governed mainly by water-permeable crack zones, and the result of the flowmeter logging show that this hole has three highly water-permeable zones. Using the results of the loggings, a correlative equation is worked out between changes in flow speed and changes in permeability index obtained by hydraulics tests. Among the various results achieved by the geophysical logging, a fine correlationship is found between an equation relative to permeability obtained using electricity and density and water-permeability indexes obtained by hydraulic tests conducted in situ. 4 refs., 8 figs., 1 tab.

This study was conducted to establish normal reference range for the Schirmer tear test (STT) and intraocular pressure (IOP) in clinically normal donkeys for use in clinical practice. Sixteen adult Ethiopian domestic donkeys were used in this study. Complete ophthalmic examinations were performed without chemical restraint. STT values were evaluated in both eyes of all donkeys using a commercial STT strip. IOP was measured in both eyes with a Tono-Pen Vet (Reichert. USA) without using regional nerve blocks. STT values for all eyes (n=32) were 22.1±6.9 mm/minute with a range of 13-35 mm/minute. Comparison of mean STT values between right (n=16) and left eyes (n=16) showed no differences (P=0.6). Mean ±sd IOP values by applanation tonometry were 17.8±3.7 mmHg (range 13.5-24.5 mmHg). Comparison of mean IOP values between right (n=16) and left eyes (n=16) showed no differences (P=0.7). This initial survey provides means and ranges for IOP and STT values in donkeys. These data will assist veterinary ophthalmologists in more accurate diagnosis and management of ophthalmic diseases in donkeys, including keratoconjunctivitis sicca and glaucoma. © British Veterinary Association (unless otherwise stated in the text of the article) 2017.

Geological disposal of high-level radioactive waste and the role of rock engineering

International Nuclear Information System (INIS)

Sugihara, Kozo

2008-01-01

Japan Atomic Energy Agency (JAEA) and its predecessors have been conducting an extensive geoscientific research program since the 1970's in order to contribute to the formation of a firm scientific and technological basis for the geological disposal of high level radioactive waste in Japan. As a part of this program, in situ experiments have been performed at the Tono Mine in soft sedimentary rocks and at the Kamaishi Mine in hard crystalline rocks. An experiment on excavation disturbance has been one of these experiments and has revealed the extent and properties of the excavation disturbed zone (EDZ) and the applicability of available measurement methods. It is suggested that mechanical excavation and controlled excavation have reduced excavation damage of the rock mass around a drift, although some improvements in the currently available methods for measuring and simulating the EDZ are essential to understand excavation disturbance in more detail. JAEA is now promoting two underground research laboratory projects in Japan; the Mizunami Underground Research Laboratory (MIU) project for crystalline rocks and the Horonobe Underground Research Laboratory (Horonobe URL) project for sedimentary rocks. From a rock mechanical point of view, the major interest in these projects will be paid to failure phenomenon deep underground, rock stress estimation at larger scales and long-term physical stability of underground structure. These projects are open for international collaboration. (author)

Full Text Available Introduction: A previous study has employed shear-wave ultrasound elastographic imaging to assess corneal rigidity in an ex-vivo porcine eye model. This study employs the same modality in vivo in a rabbit eye model in order to assess lens, ciliary body and total ocular rigidity changes following the instillation of atropine and pilocarpine. Methods: Ten non-pigmented female rabbits were examined. Measurements of the lens, ciliary body and total ocular rigidity as well as lens thickness and anterior chamber depth were taken with the Aixplorer system (SuperSonic Imagine, Aix-en-Provence, France with the SuperLinear™ SL 15-4 transducer in both eyes at baseline as well as after pilocarpine and atropine instillation. The IOP was also measured with the TonoPen tonometer. Results: Changes in rigidity in the examined areas following atropine instillation were statistically not significant. Ciliary body rigidity was significantly increased whereas lens and total ocular rigidity were significantly reduced following pilocarpine instillation. The decrease in lens rigidity following pilocarpine was significantly associated with the respective increase in ciliary body rigidity. Conclusions: Shear-wave ultrasound elastography can detect in vivo rigidity changes in the anterior segment of the rabbit eye model and may potentially be applied in human eyes, providing useful clinical information on conditions in which rigidity changes play an important role, such as glaucoma, pseudoexfoliation syndrome or presbyopia.

The decrease in lens rigidity following pilocarpine was significantly associated with the respective increase in ciliary body rigidity. Shear-wave ultrasound elastography can detect in vivo rigidity changes in the anterior segment of the rabbit eye model and may potentially be applied in human eyes, providing useful clinical information on conditions in which rigidity changes play an important role, such as glaucoma, pseudoexfoliation syndrome or presbyopia.

Japan Nuclear Cycle Development Institute has been conducting a wide range of geoscientific research in order to build a foundation for multidisciplinary studies of the deep geological environment as a basis of research and development for geological disposal of nuclear wastes. Ongoing geoscientific research programs include the Regional Hydrogeological Study (RHS) project and Mizunami Underground Research Laboratory (MIU) project in the Tono region, Gifu Prefecture. The main goal of these projects is to establish comprehensive techniques for investigation, analysis, and assessment of the deep geological environment at several spatial scales. The RHS project is a local scale study for understanding the groundwater flow system from the recharge area to the discharge area. The surface-based Investigation Phase of the MIU project is a site scale study for understanding the groundwater flow system immediately surrounding the MIU construction site. The MIU project is being conducted using a multiphase, iterative approach. In this study, the hydrogeological modeling and groundwater flow analysis of the local scale were carried out in order to set boundary conditions of the site scale model based on the data obtained from surface-based investigations in Step 1 in site scale of the MIU project. As a result of the study, head distribution to set boundary conditions for groundwater flow analysis on the site scale model could be obtained. (author)

A ampliação da distribuição geográfica e os novos registros de ocorrência de P. agmosticha, bem como sua ocorrência em diferentes formações fitofisionômicas da Caatinga e em áreas de florestas residuais e ecótonos, demonstram que, apesar de sua distribuição geográfica ser mais ampla do que se conhecia, seu padrão de distribuição relictual ainda se mantém, em virtude da ocorrência de P. agmosticha estar relacionada à ocorrência de bromélias. Contudo, o endemismo da espécie para o bioma Caatinga parece não ser absoluto.

Full Text Available TEMA: El vibrato de la voz es uno de los rasgos acústicos, técnicos y estilísticos más importantes en la caracterización de la cualidad de la voz en cantantes clásicos. Técnicamente, vibrato es una pulsación del tono, usualmente acompañada con pulsaciones sincrónicas de intensidad y timbre. El vibrato puede ser descrito acústicamente por el rate, extent y periodicidad de las modulaciones en frecuencia y modulaciones de la amplitud de la voz. El objetivo del presente artículo es mostrar y explicar un nuevo procedimiento para entrenar y corregir vibrato en cantantes. PROCEDIMIENTOS: Estudiante de canto lirico de 25 años, sexo masculino con clasificación vocal de barítono lirico, voz normal desde el punto de vista perceptual. La corrección del vibrato se realiza por medio del método "Entrenamiento rítmico del vibrato". Se produce la subdivisión rítmica de un pulso durante la emisión de una vocal con un "tempo" o velocidad constante. Posteriormente se varía la velocidad del pulso, las vocales y la melodía del ejercicio. Los parámetros acústicos del vibrato son evaluados objetivamente antes y después del entrenamiento. RESULTADOS: el paciente logró producir un vibrato con rate, extent y regularidad dentro de rangos normales. Esto se realizó de forma consciente y dirigida, utilizando actividad laríngea y abdominal en forma conjunta. La naturalidad del vibrato continuó mejorando después de finalizado el entrenamiento. CONCLUSIONES: es posible el entrenamiento y/o corrección del vibrato en forma dirigida a través de ejercicios específicos destinados a ese objetivo. El apoyo visual cumple un rol importante en los resultados obtenidos.BACKGROUND: vocal vibrato is one of the most important acoustic, technical and stylistic features to characterize the voice quality in classical singers. Technically, vibrato is a pulsation of pitch, usually accompanied with synchronous pulsations with intensity and timbre. Vibrato can be

This paper introduces Chubetsu Dam planned with a large-scale embankment having a river bed width of 600 m. Chubetsu Dam is being constructed with such objectives as flood control of Ishikari River, river flow rate maintenance, drinking water supply, irrigation water supply and power generation. The dam site is a gravel bed having a river bed width of 600 m and a maximum foundation rock thickness of 40 m, requiring evaluations as a dam foundation and discussions of water shielding methods. As a result of discussions at the Chubetsu Dam technical discussion committee, the dam type is decided to be a composition dam consisting of a gravity type concrete dam on the left river side and a central core type fill dam using a part of the gravel bed as the foundation on the right river side. A continuous underground wall system is planned to be used for shielding water in the gravel foundation. In discussing the anti-seismic properties, analyses for bank construction and water filling to derive stress and deformation conditions prior to an earthquake and a time-history response analysis to derive conditional changes during the earthquake are performed. According to the results thereof, evaluations are given on the safety by compounding the stress and the acceleration. In plans to improve the surrounding areas, an area will be provided upstream the reservoir where the water level is kept constant to serve as a bird sanctuary. 7 figs.

Full Text Available Presentamos a continuación la traducción castellana de dos textos estéticos escasamente conocidos de Frangois Fénelon, quien, universalmente conocido como autor de Les Aventures de Telemaque o por sus posiciones políticas durante el reinado de Luis XIV, no dejó de ocuparse a lo largo de su dilatada trayectoria intelectual de los problemas artísticos contemporáneos. Los textos en cuestión son dos diálogos que tienen por tema a la pintura y que, en la línea del helenismo confeso de Fénelon, imitan claramente la estructura y el tono de un cierto género de diálogos literario-filosóficos griegos cuyo máximo exponente sería Luciano de Samosata y que pretenden reproducir imaginarias conversaciones, siempre de corte moralizante, celebradas en el Hades entre las almas de graneles personajes de la Historia. De hecho, los dos diálogos sobre la pintura fueron originalmente escritos para una obra de mayor envergadura, los Dialogues des Morts (1712, en los que se incluían diálogos con temáticas muy variadas pero casi siempre girando en torno a la misma problemática ética y a la reflexión política sobre la naturaleza del poder ya presente, como es bien conocido, en el Telemaque.

The results of groundwater flow modeling are to be justified using groundwater monitoring data in the hydrogeological characterization. On the other hand, hydraulic continuities of the geological structures, all of which are considered to have great effect on groundwater flow and/or groundwater quality, are to be estimated using the groundwater flow monitoring data with hydraulic response to some impacts such as borehole drilling, pumping test and so on. Therefore, the groundwater monitoring is important for characterizing the geological and hydrogeological environments. In order to characterize of hydrogeological environment using the monitoring data, it is important to evaluate the influence of artificial and natural impact on the monitoring data. In this study, the following three research works are carried out based on the groundwater monitoring data collected at the Tono area. Artificial Neural Network (ANN) was adopted as the tool for monitoring data analysis. Runoff analysis for assessment of importance of soil moisture on runoff estimation in a catchment. Analysis of water level fluctuation for determination influence factors in the water level fluctuation and for filtering out the influence factors from the water level data . Analysis of hydraulic pressure fluctuation in deep geological formations for hydrogeological characterization and assessment of human influence on the pore pressure in deep formation. Through this study, applicability of ANN for analysis and interpretation of the groundwater monitoring data could be confirmed and methodology for utilization the monitoring data for understanding and characterization of hydrogeological environment could be developed.

The research is one of the program which was planned by PNC (Power Reactor and Nuclear Fuel Development Corporation). In this research the analyses of the uranium series nuclide of rock samples from uranium Tono deposit, Japan have been carried out. The 17 samples were collected from Tsukiyoshi Fault, at Gallery X on Shaft 2 consist of granite, sedimentary rocks and fault area. The aim of the research is to determine the area of U accumulation, equilibrium and leaching. The samples were treated by chemical reagent, separated by ion exchange resin and extracted by organic compounds. The uranium and thorium were deposited on the stainless steel plate surface by the electrolysis process. The activity of uranium and thorium was determined by alpha spectrometer. From the analyses data have been obtained that shows that the maximum activity of 238 U is 3.6798±0.1873 Bq/g, activity 234 U is 3.5450±0.1805 Bq/g and activity 230 Th is 3.6720±0.1868 Bq/g. The ratio figure 234 U/ 238 U versus 2 34 U / 2 30 T h has been drawn. As the conclusion, 6 samples point (No.3, 5, 8, 11, 13 and 16) lied in or on the boundary of the uranium accumulation area, 7 samples (No. 4, 6, 9, 10, 12, 15 and 17) are very close to the equilibrium position, 4 points (No. 1, 2, 7, and 14) in the leaching process.

Interaction between carbon blacks and oxygen molecules has been studied by means of electron spin resonance (ESR) spectroscopy. The ESR spectra of the carbon blacks appears at the g-value of free spin, which are contributed by both isolated electrons and conduction electrons. Upon introducing oxygen to the system the ESR linewidth was broadened in proportion to the partial pressure of oxygen. In case of lampblack (LB 101, Degussa) the interaction was not so strong that it took a tong time at 77K for the linewidth to reach the maxmum value. In case of gassblack (P 140 V, Degussa), on the other hand, the oxygen was easily adsorbed at 298K and the linewidth at 77K became its maximum immediately after cooling. The number of unpaired electrons decreased when the system was kept at 298 K and the decrease was prominent for the local spins. These phenomena have been explained with a simple band model for the electron. (author)

Intraarticular steroid injections are a common first-line therapy for severe osteoarthritis, which affects an estimated 27 million people in the United States. Although topical, oral, intranasal, and inhalational steroids are known to increase intraocular pressure in some patients, the effect of intraarticular steroid injections on intraocular pressure has not been investigated, to the best of our knowledge. If elevated intraocular pressure is sustained for long periods of time or is of sufficient magnitude acutely, permanent loss of the visual field can occur. How does intraocular pressure change 1 week after an intraarticular knee injection either with triamcinolone acetonide or hyaluronic acid? A nonrandomized, nonblinded prospective cohort study was conducted at an outpatient, ambulatory orthopaedic clinic. This study compared intraocular pressure elevation before and 1 week after intraarticular knee injection of triamcinolone acetonide versus hyaluronic acid for management of primary osteoarthritis of the knee. Patients self-selected to be injected in their knee with either triamcinolone acetonide or hyaluronic acid before being informed of the study. The primary endpoint was intraocular pressure elevation of ≥ 7 mm Hg 1 week after injection. This cutoff is determined as the minimum significant pressure change in the ophthalmology literature recognized as an intermediate responder to steroids. Intraocular pressure was measured using a handheld Tono-Pen® applanation device. This device is frequently used in intraocular pressure measurement in clinical and research settings; 10 sequential measurements are obtained and averaged with a confidence interval. Only measurements with a 95% confidence interval were used. Over a 6-month period, a total of 96 patients were approached to enroll in the study. Sixty-two patients out of 96 approached (65%) agreed. Thirty-one (50%) were injected with triamcinolone and 31 (50%) were injected with hyaluronic acid. Patients

El objetivo fue cuantificar ambas pigmentaciones en una muestra de población mexicana, y analizar su relación con el género, edad y fototipo. Se evaluaron 259 personas durante un periodo invernal. La colorimetría cutánea se obtuvo mediante espectrometría de reflectancia difusa utilizando las coordenadas de la Comisión Internacional de Iluminación. Se registraron los valores L*a*b* y se estimó el ángulo tipológico individual (ATI°) en frente, tórax, cuello, antebrazos y glúteos. La pigmentación facultativa difirió de la constitutiva en los parámetros L*, a*, y ATIº. En hombres, los valores facultativos de L* y ATI° fueron menores. La pigmentación constitutiva fue similar entre sexos. Los fototipos III, IV y V muestran diferencias en L*, b* y ATI°. Los valores facultativos L*, a*, ATI° y el constitutivo a* se reducen al incrementarse la edad. Se cuantificaron los tonos cutáneos de una muestra de población reconociéndose los valores para la piel blanca, morena clara y morena oscura. Se presenta un marco de referencia para estudios relacionados con la pigmentación cutánea en México. Copyright: © 2018 SecretarÍa de Salud

Full Text Available El presente artículo desarrolla la hipótesis según la cual el predominio de la estilística obturó la recepción de los aspectos más fecundos y renovadores del paradigma epistemológico estructuralista. Para ello examinamos dos momentos: En primer lugar, las iniciales consideraciones de Dámaso Alonso en torno a Saussure, como hecho inaugural de esa recepción condicionada. Luego, analizamos dos títulos de principios de la década del setenta: Significado actual del formalismo ruso (1973, de Antonio García Berrio; y La semiótica como teoría lingüística (1973, de María del Carmen Bobes Naves. Lo que perseguimos en esta segunda parte es mostrar hasta qué punto las opiniones de Alonso siguen condicionando la recepción del estructuralismo en un momento clave para la renovación teórica de la crítica literaria española; y eso, además, para obras de tono y perspectivas muy disímiles, de las que puede decirse que representan polos opuestos  en un contexto, el de los últimos años de la dictadura franquista, que fue de gran agitación en el ámbito universitario, y en el que a menudo las demandas por la dignificación laboral y la democratización de las instituciones, se hermanaron con las de actualización y modernización de los planes de estudio.

Full Text Available AIM: To present a new, simple, inexpensive Schlemm canal microcatheter for circumferential canaloplasty in a rabbit model. METHODS: A rabbit glaucoma animal model was established by intravitreal injection of triamcinolone acetonide. Circumferential canaloplasty with a new Schlemm canal microcatheter (patent license number: 201220029850.0 was performed. The Schlemm canal microcatheter was composed of microcatheter wall and lumen. The wall was made of high refractive index plastic optical fiber that could be attached to an illuminant so that the whole lighted microcatheter was visible during circumferential canaloplasty. The lumen could be attached to an injector for injection of viscoelastic during catheterization. Rabbits were divided randomly into the control, model and treatment groups. Intraocular pressure (IOP was measured with a Tono-pen tonometer pre-operation and 3, 7, 14, 21 and 28d post-operation. Ultrasound biomicroscopy was performed to visualize the Schlemm canal microcatheter in the Schlemm canal and the sclera pool. RESULTS: The Schlemm canal microcatheter could be used to perform circumferential canaloplasty in the rabbit glaucoma animal model. IOP was lower in the treatment group than that in the model group 3, 7, 14 and 28d after operation. There were no significant differences in IOP between the control group and treatment group. The differences among the three groups were statistically significant (3d: F=41.985, P<0.001; 7d: F=65.696, P<0.001; 14d: F=114.599, P<0.001; 28d: F=55.006, P<0.001. CONCLUSION: Circumferential canaloplasty is safe and effective in control of experimental glaucoma model in rabbits.

En el mundo en la formación de los Atletas del Ciclismo solo se realiza el entrenamiento deportivo, es decir se tiende a hacer al hombre y la mujer una máquina que maneja otra máquina. En los tiempos actuales están ocurriendo profundos cambios tecnológicos en el área del ciclismo. La globalización es una variable relevante a tener en cuenta como resultado inevitable del desarrollo histórico de la sociedad, sus fuerzas productivas y el desarrollo de la ciencia y la técnica. El desarrollo del deporte en Latinoamérica incluido el Ciclismo tiene que estar a tono con las tendencias innovadoras que se están desarrollando en este “Cambio de Época”. El paradigma que debe regir en nuestros países es el rescate de los principios del amateurismo, adecuados a las condiciones económicas actuales y cuya base de realización debe ser un paradigma humanista. Un modelo de escuela para cualquier deporte y en particular para el ciclismo, debe contener en su concepción una triada obligatoria: la formación ciudadana, la formación cultural general integral, la formación deportivas estructuradas y coherentemente desarrolladas

As of November 1996, Japan's total installed commercial nuclear power generation capacity was 42 GW(e), accounting for 34% of total electric energy generation. By 2010, Japan intends to have an installed electricity generation capacity of 70.5 GW(e). This will increase the country's demand for nat Ural uranium from 7,700 t U in 1994 (13% of the world consumption) to 13,800 t U in 2010 (17%-19% of the world projected consumption). However, Japan's known uranium resources at Ningyo-Toge and Tono deposits, are estimated at roughly only 6,600 t U. The Long-term Programme for Research, Development and Utilization of Nuclear Energy (adopted in 1994) calls for diversification through long-term purchasing contracts, independent exploration and involvement in mining vent Ures, with the objective of ensuring independence and stability in Japan's development and utilization of nuclear energy. The Power Reactor and Nuclear Fuel Development Corporation (PNC) has been commissioned to carry out the task of independent exploration. PNC is carrying out exploration projects in Canada, Australia, USA and China targeting unconformity related type deposits with an eye to privatizing them. Currently about 40,000 t U of uranium resources are held by PNC. PNC has been carrying out the following related activities: (1) Reference surveys on uranium resources to delineate the promising areas; (2) Development of uranium exploration technology; (3) Information surveys on the nuclear industries to project long-term supply and demand; (4) International Cooperation programme on uranium exploration with Asian countries.

Full Text Available Desde hace por lo menos una década, se ha insistido mucho en la orientación mundial del turismo como una opción de desarrollo. Visto a través de estudios de mercadotecnia, este sector económico, sea cual sea su versión, ha proliferado y sentado sus reales en los rincones más remotos del planeta. Del lado de las ciencias sociales existen investigaciones antropológicas abo - cadas a diversos temas; uno de ellos refiere una extensión del paradigma de la otredad al estudiar los procesos de reconocimiento del otro en contextos turísticos. Una línea de trabajo más a tono en México, guiada por la noción de patrimonio, coloca al centro la explotación de los recursos culturales y naturales como fuente de atractivos para visitantes. A partir de estas dos perspectivas se presenta el caso del turismo gay en Cancún, ubicado en la demandante región del Caribe mexi - cano, cuyo despegue e intentos de consolidación como segmento turístico enfrentan diversos di - lemas de orden social y político. En ese entorno se analizan las prácticas de consumo en donde las identidades colectivas se debaten frente a modelos hegemónicos expuestos en los espacios socia - les de interacción creados por el mercado y apropiados como escenarios de contienda simbólica.

Full Text Available Durante el embarazo aumentan el metabolismo basal, el consumo de O2, la frecuencia cardíaca, el volumen sistólico, el volumen minuto y la volemia y disminuyen la tensión arterial y la resistencia periférica. Diferentes estudios han demostrado que durante este período la posibilidad de que ocurra una arritmia cardíaca o se produzca la exacerbación de una arritmia preexistente es mayor. No obstante, en su enorme mayoría carecen de importancia pronóstica tanto para la madre como para el feto. La taquicardia ventricular del tracto de salida del ventrículo derecho es una arritmia poco frecuente y su aparición se ha correlacionado con el aumento del tono adrenérgico. Se presentan los casos de dos pacientes que mostraron en el curso de la gestación reiterados episodios de taquicardia ventricular del tracto de salida del ventrículo derecho. Se analiza la asociación del embarazo con la ocurrencia de trastornos del ritmo cardíaco.During pregnancy, there is an increase in metabolism, oxygen consumption, heart rate, stroke volume, cardiac output, blood volume and a decrease in blood pressure and peripheral resistance. Studies have shown that during this period the occurrence of cardiac arrhythmias is not uncommon. Fortunately, malignant arrhythmias are rare. Herein we report two young patients who presented with symptomatic right ventricular outflow tachycardia during pregnancy that required antiarrhythmic therapy. Possible pathophysiologic mechanisms are discussed.

Full Text Available Drosophila melanogaster, la mosca de la fruta, es un organismo genético modelo que en años recientes se ha usado exitosamente para estudiar el control del metabolismo y el crecimiento. A pesar de poseer algunas diferencias con las vías de señalización homólogas a las de los vertebrados, las semejanzas son profundas y claras. En D. melanogaster, la vía de la insulina, homóloga a la de los vertebrados, regula tanto el metabolismo como el crecimiento del organismo a través de un receptor membranal único. A su vez, esta vía –que conjunta lo que en vertebrados es la vía de la insulina y la de los péptidos parecidos a la insulina- está regulada por la ingesta de nutrientes (carbohidratos y proteínas y por el control hormonal (hormona del crecimiento, ecdisona, upd2, hormona adipocinética, Ilp8. En consecuencia, normalmente se obtiene un crecimiento adaptable a las condiciones nutricionales que influye, como en los vertebrados, en el promedio de vida y en la capacidad reproductiva con un tamaño típico y una diferenciación armónica, a tono con el bauplandel organismo. Por el contrario las mutaciones y desviaciones dan por resultado partes desproporcionadas, menor capacidad reproductiva, y disminución tanto del tamaño como de la proliferación, y hasta la muerte.

2016-11-01

Full Text Available Este artículo propone una crítica a ciertas tendencias dentro de los estudios sobre genocidio, entre las que aparecen el abuso del prestigio y de la obra de Lemkin, el alejamiento frente a las posturas del activismo académico contra el genocidio, el tono displicente con el que se aborda la agencia política de los grupos de víctimas, las tendencias relativistas del concepto de “políticas de la memoria” y su implementación, la creciente institucionalización del campo, el concepto de “generocidio” y la imagen opaca que supone la violencia genocida dirigida contra mujeres y niñas, el foco en la deshumanización como condición para el genocidio y el énfasis en las advertencias tempranas. El artículo también discute una nueva estrategia negacionista del genocidio. A la luz de ello, las advertencias tempranas sobre el genocidio son, en gran medida, inoperantes. Más allá de la indiferencia política que explica la existencia de genocidios perpetrados incluso en la actualidad, la preeminencia de este delito se debe al hecho de que el orden mundial del presente y muchas sociedades específicas fueron moldeados por el genocidio y la violación en masa y la opresión vinculadas con ese primer crimen. El artículo sostiene que un proceso global de reparación podría ayudar a encauzar el mundo y alejarlo de los fundamentos y tendencias genocidas.

As a Phase 1 of MIU project (Mizunami Underground Research Laboratory project), through the laboratory and borehole in-situ tests, JNC Tono Geoscience Center plans to constitute the comprehensive geological model and predicts the rock behaviors in excavating the shaft and gallery. These model and results leads to be reflected by the next step research projects. So far, the Phase 1 of MIU project is coming to final stage, and the Phase 2 will start at next year in which the in-situ researches are planned through the excavation. In this study, the comprehensive geometrical model was drawn out through the Phase 1 data, and MBC model analysis was carried out to predict the rock mass behavior around the shaft and gallery. The following results are obtained. 1. With MIZ-1 borehole core, artificial joints, which are assumed to be produced by rock blasting, were formed through the Brazilian test. And through the rock shear test for these joints, these mechanical properties were obtained. 2. By examining the MIZ-1 borehole research data, Mizunami site was classified by mechanical and joint properties and the Geomechanical model were made up. 3. Through the MBC model, the shaft and gallery cases were analyzed which depend on the rock mass classification, Excavation Damaged Zone, and the direction of the galleries. These results showed that in most cases, the joint opening were little because of the rock stiffness, but by the existence of high inclined joints, the side wall of the galleries were damaged by the excavation.

Japan Nuclear Cycle Development Institute has been conducting a wide range of geoscientific research in order to build a foundation for multidisciplinary studies of the deep geological environment as a basis of research and development for geological disposal of nuclear wastes. Ongoing geoscientific research programs include the Regional Hydrogeological Study (RHS) project and Mizunami Underground Research Laboratory (MIU) project in the Tono region, Gifu Prefecture. The main goal of these projects is to establish comprehensive techniques for investigation, analysis, and assessment of the deep geological environment at several spatial scales. The RHS project is a local scale study for understanding the groundwater flow system from the recharge area to the discharge area. The Surface-based Investigation Phase of the MIU project is a mainly site scale study for understanding the deep geological environment immediately surrounding the MIU construction site using a multiphase, iterative approach. In this study, the hydrogeological modeling and groundwater flow analysis on the Local scale were carried out in order to set boundary conditions of the site scale model based on the data obtained from surface-based investigations in the former part of the Step 3 in site scale of the MIU project. As a result of the study, the uncertainty of hydrogeological model of the local scale and boundary conditions for the site scale model is decreased as stepwise investigation, and boundary conditions for groundwater flow analysis on the site scale model for the former part of the Step 3 could be obtained.

An investigation was given on the relationship between methanol adsorbing behavior of reformed coal surface and oxygen containing functional groups in coal. Akabira bituminous coal was air-oxidized or Yallourn brown coal was decarbonated in oil as a reformation treatment. Both of the treated and untreated coals showed an adsorption heat curve of the Langmuir type. The Akabira coal had its oxygen content and the adsorption heat increased as a result of the air oxidizing reformation treatment. The Yallourn coal had its oxygen content and adsorption heat decreased as a result decarbonation reformation treatment. Oxygen containing functional groups act as strong adsorption sites for methanol, and the maximum adsorption amount depends on oxygen content in the coals. Since the coal surface is non-uniform in terms of energy, methanol is adsorbed first into sites with higher molar adsorption heat, and then into lower sites sequentially. Therefore, distribution of the molar adsorption heat can be derived from the relationship between adsorption amount and adsorption heat by changing methanol adsorption amount. The distribution of molar adsorption heat becomes broader when the oxygen content is high, and narrower when low. 2 refs., 2 figs.

Full Text Available This study aimed to evaluate changes in lacrimation and intraocular pressure (IOP in dogs with unilateral corneal ulceration using the Schirmer tear test (STT and rebound (TonoVet® tonometry. IOP and STT values were recorded in both ulcerated and non-ulcerated (control eyes of 100 dogs diagnosed with unilateral corneal ulceration. Dogs presented with other ocular conditions as their primary complaint were excluded from this study. The mean ± standard deviation for STT values in the ulcerated and control eyes were 20.2±4.6 mm/min and 16.7±3.5 mm/min respectively. The mean ± standard deviation for IOP in the ulcerated and control eyes were 11.9±3.1 mmHg and 16.7±2.6 mmHg respectively. STT values were significantly higher (p<0.000001 in the ulcerated eye compared to the control eye while IOP was significantly lower (p<0.0001. There is an increase in lacrimation and a decrease in IOP in canine eyes with corneal ulceration. The higher tear production in ulcerated eyes shows the importance of measuring STT in both eyes in cases of corneal ulceration, since this increased lacrimation may mask an underlying keratoconjunctivitis sicca only evident in the contralateral eye. The lower IOP in ulcerated eyes is likely to relate to mild uveitic change in the ulcerated eye with a concomitant increase in uveoscleral aqueous drainage. While these changes in tear production and IOP in ulcerated eyes are widely recognised in both human and veterinary ophthalmology, it appears that this is the first controlled documented report of these changes in a large number of individuals.

Study on long-term stability of geochemical environments at deep underground

Mizuno, Takashi; Iwatsuki, Teruki

2005-01-01

Observation and fluid inclusion analysis of fracture filling calcites in granite at the Tono area were conducted to assess long-term stability of geochemical environment at deep underground. The result of observation using SEM and luminoscope shows that precipitation processes of calcite can be divided into four phases (1 to 4) based on their occurrence. (1) Phase 1: indistinct morphology and includes the wall rock fragments. (2) Phase 2: rhombohedral and hexagonal form. (3) Phase 3: elongate rhombohedral form, growth over the layer of phase 2 calcite. (4) Phase 4: small rhombohedral form crystals growth from surface of phase 3 calcite. On Phase 1 calcite, it seems to be hydrothermal origin related to fracture activation. Previous study shows the correlation between the salinity of fluid from which calcite precipitated and morphology of calcite. According to previous studies, the groundwater from which phase 3 calcite precipitated would be the highest salinity such as seawater. Phase 2 and 4 calcite may be precipitated from groundwater with low salinity. On the other hand, fluid inclusions were recognized in phase 2 and 3 calcite. All inclusions indicated mono-phase (liquid phase). These suggest that phase 2 and 3 calcites were precipitated in low-temperature condition. Result of salinity analysis indicates that two groundwaters having different chemical properties had existed during phase 2 and 3 calcite precipitation. Based on these results, geochemical environment had changed by input of high salinity groundwater during Phase 2 and 3 calcite precipitation. It is required to identify the origin of each groundwater in consideration of historical geology for further understanding of long-term hydrochemical condition. (author)

In an effort to reach an economic, ecologic and electrogenic consensus, this time we search to point out an economic model that does not go against the energy changes occurring in nature and which conciliates the eternal technology's ambivalence for being a source of both benefits and adverse effects. Thus, taking advantage of this technology an economic model is established in accordance to the global ecosystem taking into account wastes and consumption: the Constanza Daly proposal. A proposal that does not aim to reduce CO{sub 2} emissions nor to lock them up for a future disposal, but looks for conforming to the nature, unfolding the CO{sub 2} and processing it in artificial sinks at a velocity equal or greater to its generation. Thus, perpetuating its use when controlling the adverse effects.

Yielding physically-interpretable emulators - A Sparse PCA approach

Science.gov (United States)

Galelli, S.; Alsahaf, A.; Giuliani, M.; Castelletti, A.

2015-12-01

Projection-based techniques, such as Principal Orthogonal Decomposition (POD), are a common approach to surrogate high-fidelity process-based models by lower order dynamic emulators. With POD, the dimensionality reduction is achieved by using observations, or 'snapshots' - generated with the high-fidelity model -, to project the entire set of input and state variables of this model onto a smaller set of basis functions that account for most of the variability in the data. While reduction efficiency and variance control of POD techniques are usually very high, the resulting emulators are structurally highly complex and can hardly be given a physically meaningful interpretation as each basis is a projection of the entire set of inputs and states. In this work, we propose a novel approach based on Sparse Principal Component Analysis (SPCA) that combines the several assets of POD methods with the potential for ex-post interpretation of the emulator structure. SPCA reduces the number of non-zero coefficients in the basis functions by identifying a sparse matrix of coefficients. While the resulting set of basis functions may retain less variance of the snapshots, the presence of a few non-zero coefficients assists in the interpretation of the underlying physical processes. The SPCA approach is tested on the reduction of a 1D hydro-ecological model (DYRESM-CAEDYM) used to describe the main ecological and hydrodynamic processes in Tono Dam, Japan. An experimental comparison against a standard POD approach shows that SPCA achieves the same accuracy in emulating a given output variable - for the same level of dimensionality reduction - while yielding better insights of the main process dynamics.

In an effort to reach an economic, ecologic and electrogenic consensus, this time we search to point out an economic model that does not go against the energy changes occurring in nature and which conciliates the eternal technology's ambivalence for being a source of both benefits and adverse effects. Thus, taking advantage of this technology an economic model is established in accordance to the global ecosystem taking into account wastes and consumption: the Constanza Daly proposal. A proposal that does not aim to reduce CO{sub 2} emissions nor to lock them up for a future disposal, but looks for conforming to the nature, unfolding the CO{sub 2} and processing it in artificial sinks at a velocity equal or greater to its generation. Thus, perpetuating its use when controlling the adverse effects. [Spanish] En un esfuerzo por conjugar economia, ecologia y energia, en esta ocasion se busca hacer notar un modelo economico que no vaya en contra de los cambios energeticos que ocurren en la naturaleza, conciliando al mismo tiempo la eterna ambivalencia de la tecnologia, fuente de beneficios y efectos adversos. Asi, echando mano de la tecnologia misma, se fundamenta un modelo economico a tono con el ecosistema global, que toma en cuenta desechos y consumo: La propuesta de Constanza Daly. Una propuesta que, aun con retos por delante, no busca disminuir la emision de CO{sub 2} ni encerrarlo para un desecho futuro, sino busca conformarse a la naturaleza desdoblando el CO{sub 2} y procesandolo en sumideros artificiales a una velocidad igual o mayor a la de generacion; perpetuando asi su uso al controlar los efectos adversos.

During surgery, changes in intraocular pressure (IOP) can be observed resulting from several factors, such as airway manipulations and drugs used. We aimed to investigate the effects of sugammadex and neostigmine on IOP, hemodynamic parameters, and complications after extubation. Our study comprised 60 patients, aged 18-65 years, with a risk status of the American Society of Anesthesiologists I-II who underwent arthroscopic surgery under general anesthesia. The patients were randomly assigned into two groups. At the end of the surgery, the neuromuscular block was reversed using neostigmine (50 μg/kg) plus atropine (15 μg/kg) in Group 1, and sugammadex (4 mg/kg) in Group 2. Neuromuscular blockade was monitored using acceleromyography and a train-of-four mode of stimulation. IOP was measured before induction and at 30 seconds, 2 minutes, and 10 minutes after extubation. A Tono-Pen XL applanation tonometer was used to measure IOP. This showed that elevation in IOP of patients reversed using sugammadex was similar to that recorded in patients reversed using neostigmine-atropine. When heart rate was compared, there was a significant difference between basal values and those obtained at 30 seconds and 10 minutes after extubation in the neostigmine-atropine group. Extubation time (time from withdrawal of anesthetic gas to extubation) was significantly shorter in the sugammadex group (p = 0.003) than in the neostigmine-atropine group. The postextubation IOP values of the sugammadex group were similar to the neostigmine-atropine group. Extubation time (time from withdrawal of anesthetic gas to extubation) was significantly shorter in the sugammadex group (p = 0.003) than in the neostigmine-atropine group. Copyright © 2016.

This progress report (H22 Report) documents progress made during JAEA 1st Midterm Plan (FY 2005 - 2009) to provide the scientific base for assessing geosphere stability for long-term isolation of the high-level radioactive waste. For the current 5-year R and D programme, three major goals have been defined as follows: 1) development and systematization of investigation techniques for selecting suitable sites in geosphere stability, 2) development, application and verification of prediction models for evaluating the changes of geological environment in thermal, hydraulic, mechanical and geochemical conditions for a long period of time, and 3) development of new dating techniques for providing information about geologic history and the timing of geologic events. For investigation techniques, an extracting technique of active faults with weak surface expressions by LiDAR, an integrated approach combining geophysical and geochemical methods for detecting crustal magma storage and an estimating method for uplift rates in an inland area using relative heights of fluvial terraces have been made. A numerical simulation code for predicting landform evolution in the next 100,000 years, and incorporating models of geophysical processes directly into probabilistic assessments for renewed volcanism using Bayesian inference (multiple inference model) have been prepared for prediction models. Improvement of AMS system for 14 C dating was conducted in order to precisely determine isotopic compositions. (U-Th)/He and K-Ar dating systems were also installed at Tono Geoscience Center (TGC) for determining the production age of fault gouge and precipitated within open fractures. In this paper, the current status of R and D activities with previous scientific and technological progress is summarized. (author)

Radionuclide migration toward the human environment is to be assessed as the part of long-term safety assessments of geologic disposal of radioactive waste. Geologic processes, which include volcanic activity, hydrothermal activity, seismicity and deformation, bring about hydrogeologic changes in the regional groundwater flow system around a repository site. Groundwater flow systems in Japan have been studied in several sites such as Tono mine, Kamaishi mine and Horonobe area, but methodology of studies in these sites does not have fully developed. This study was conducted to develop methodologies of boundary delineation for regional groundwater flow systems. Geographic Information System, GIS, was applied using available topographic, hydrologic and geologic data for an area of interest. Miyakoji in the Abukuma Mountains was selected as the area, for the reason of its simple geologic setting formed by granitic rocks and topographically gentle hills of drainage basin. Data used in this study cover topographic sheets, digital elevation model, satellite imagery, geologic maps, topographic classification maps, soil distribution maps and landuse maps. Through the GIS techniques using these data, thematic maps on topographic features, surface conditions, land coverage, geology and geologic structure and weathered crust were developed, and these thematic maps were further applied to extract four factors affecting the regional groundwater flows: topographic condition, precipitation recharge, fracture characteristics and potential flows. The present study revealed that, taking the potential groundwater flows and characteristics of fractured zones in the area into consideration, the groundwater flow system in Miyakoji drainage basin should be bounded by the Otakine Mountain and the northern part of Tokoha Drainage Basin. The delineated area is larger than understood before. (author)

Full Text Available Esta propuesta parte de las particularidades de la formación en Lengua A para Traductores, un ámbito poco definido y normalmente muy alejado de los contenidos literarios. Se plantean dos conjuntos de actividades, vinculados a la evaluación y a la reescritura, de cuya vinculación surgen los conceptos de lectura intencional y desautomatización de la escritura, y que parecen por tanto especialmente adecuadas para fomentar una creatividad en el uso de la lengua que resulta de la mayor importancia para la traducción literaria. A partir de unas primeras experimentaciones con reescritura de textos literarios, se puede concluir que las nociones de tono y estilo están intuitivamente disponibles para los escritores noveles y son por tanto excelentes candidatas para ser operativas en la formación en traducción literaria.  The distinguishing characteristics of First Language training - a vaguely defined area of study which is not usually explored in literary publications - will form the basis of our investigation.  We will consider two sets of activities, both linked to evaluation and rewriting, which will allow us to explore the concepts of intentional reading and deautomisation of the writing process. These notions seem especially useful for encouraging creativity in language use, a highly important skill in literary translation. Based on the results of a few initial experiments involving the rewriting of literary texts, we can conclude that novice writers are intuitively aware of tone and style. These notions could therefore provide an excellent focus for literary translation training.

Full Text Available Abstract - Chick lit is a genre comprised of books chiefly written by women for women. These books are mainly characterized by the tone, which is very confidential and personal, and often relies on the use of colloquial and slangy (and occasionally obscene expressions, by the use of humour, and by the numerous references to popular culture. This paper aims at analyzing the strategies used in the Italian translation of one of the best-known examples of the genre, Helen Fielding’s Bridget Jones’s Diary, taking two frames of reference. First of all, the analysis will try to identify in the target text the distinctive universal features observed in computer-based corpus translation (Baker 1996, namely explicitation, simplification and normalization. Secondly, it will consider the translation in terms of Venuti’s dichotomy of translation strategies into domestication and foreignization (1995. Riassunto -Il chick lit è un genere letterario costituito principalmente da romanzi scritti perlopiù da autrici donne per un pubblico femminile.

Questo saggio intende analizzare le strategie utilizzate nella traduzione italiana di uno degli esempi più rappresentativi del genere, ovvero Bridget Jones’s Diary di Helen Fielding, utilizzando due modelli di riferimento. Innanzitutto, lo studio tenterà di identificare la presenza degli universali traduttivi osservati nei corpus-based translation studies (Baker 1996, ovvero explicitation, simplification e normalization.

The peak period of the horizontal/vertical spectral ratio of microtremors was referred to the underground structure for the purpose of finding out if it was possible to estimate the ground structure by use of the peak period of the spectral ratio. The observation was carried in the areas of Morioka City and Hachinohe City using seismographs for measuring east-west, north-south, and up-down motions. As for the relationship between the peak period of the spectral ratio distribution involving 490 observation sites and the known gravity anomalies in the Morioka City area, it was found that the peak period of the spectral ratio tended to be shorter from west toward east while the gravity anomalies were greater from west toward east. Again, as for the relations with the underground geology, the period was longer when the distance to the granite basement was greater, and shorter when smaller. In the Hachinohe City area, relations not only of the first period peak but also of the second period peak to the basement were disclosed, which indicates the possibility that the peak period of the spectral ratio will be used as a means for estimating the basement structure. 2 refs., 8 figs.

With an objective of proposing to ISO a thermal environment evaluation method, development has been performed on an evaluation technology to evaluate comfort and discomfort in non-constant and non-uniform thermal environment, and research has been carried out on structuring an evaluation standard. This paper summarizes the achievements in fiscal 2000. In developing the evaluation technology by using a 'human body thermal model' it was verified that the 'human body thermal model' being the achievement of the project to develop the human sensitivity measurement applied technology is effective as a method to evaluate non-uniform thermal environment, as a result of the experimental verification of the human testees. With regard to the effects on human body of thermal transient based on the testee experiment, such basic findings were derived that the thermal transient affects the psychological reaction even after movement, and that thermal sensitivity of aged persons of both sexes, and young generation shows greater positional difference in peripheral sections than in the trunk sections. The major standard being the object of this research is ISO 7730, for which discussions were given on the revision draft for the floor heating standard and the transient standard, the evaluation method using a human body model, and the evaluation method using a thermal mannequin as the new standards.

Purpose. To study anatomical changes and mechanical behavior of the sclera in mice with experimental glaucoma by comparing CD1 to B6 mice. Methods. Chronic experimental glaucoma for 6 weeks was produced in 2- to 4-month-old CD1 (43 eyes) and B6 mice (42 eyes) using polystyrene bead injection into the anterior chamber with 126 control CD1 and 128 control B6 eyes. Intraocular pressure (IOP) measurements were made with the TonoLab at baseline and after bead injection. Axial length and scleral thickness were measured after sacrifice in the CD1 and B6 animals and compared to length data from 78 eyes of DBA/2J mice. Inflation testing of posterior sclera was conducted, and circumferential and meridional strain components were determined from the displacement response. Results. Experimental glaucoma led to increases in axial length and width by comparison to fellow eyes (6% in CD1 and 10% in B6; all P glaucoma, the remainder of the sclera uniformly thinned in CD1, but thickened in B6. Peripapillary sclera in CD1 controls had significantly greater temporal meridional strain than B6 and had differences in the ratios of meridional to effective circumferential strain from B6 mice. In both CD1 and B6 mice, exposure to chronic IOP elevation resulted in stiffer pressure–strain responses for both the effective circumferential and meridional strains (multivariable regression model, P = 0.01–0.03). Conclusions. Longer eyes, greater scleral strain in some directions at baseline, and generalized scleral thinning after glaucoma were characteristic of CD1 mice that have greater tendency to retinal ganglion cell damage than B6 mice. Increased scleral stiffness after glaucoma exposure in mice mimics findings in monkey and human glaucoma eyes. PMID:23404116

As an Integral part of the geological survey in 'The study of the regions ground water flow system' that we are carrying out with Tono Geoscience Center, we proved the relation between the uncontinuation structure such as lineament in the base rock and resistivity structure (resistivity distribution), for the purpose of that confirms the efficacy of the high resolution electrical survey as geological survey, we carried out high resolution electrical survey on granite area. We obtained the following result, by the comparison of resistivity distribution with established geological survey, lineament analysis and investigative drilling. 1. The resistivity structure of this survey area is almost able to classify it into the following four range. 1) the low resistivity range of 50-800 Ωm, 2) The resistivity range like the middle of 200-2000 Ωm, 3) The high resistivity range of 2000 Ωm over, 4) The low resistivity range of depth of the survey line 400-550 section. 2. The low resistivity range of 4) that correspond with the established geological data is not admitted. 3. It was confirmed that resistivity structure almost correspond to geological structure by the comparison with the established data. 4. The small-scale low resistivity area is admitted in the point equivalent to the lineament position of established. 5. We carried out it with the simulation method about the low resistivity range of 4). As a result, it understood that it has the possibility that the narrow ratio low resistivity area is shown as the wide ratio resistivity range in the analysis section. In the survey in this time, it is conceivable that the resistivity distribution with the possibility of the unhomogeneous and uncontinuation structure of the base rock is being shown conspicuously, the efficacy of the high resolution resistivity survey as geological survey on granite was shown.

Blanco sobre blanco : la arquitectura y el cambio cromático

Full Text Available El color tiene un impacto considerable en la percepción general del paisaje urbano. La luz resalta las superficies, la textura subraya los materiales. Cuando en un paisaje se realiza cualquier intervención, ésta se convierte en atracción visual en relación a su contexto, siendo necesario considerar los factores determinantes de esta nueva relación. El empleo del blanco brillante supone introducir un elemento perceptivo fuerte. Paradójicamente, es el color más agresivo. Los materiales naturales, como la propia naturaleza, tienden a ser complejos en su textura y en sus tonos. El uso generalizado de productos industriales está conduciendo a un empobrecimiento cromático de los paisajes urbanos. El futuro del color blanco pasa por un cambio en su concepción de elemento decorativo hasta convertirlo en fundamento del proyecto, aprovechando sus cualidades de gradación tonal, contraste, expansión espacial y composición de escalas y formas.The colour has a significant impact on the overall perception of an urban environment. Light plays on surfaces, the texture of materials are noticed. Since any object introduced into the environment becomes a visual target in relation to its context, it is necessary to considerer the factors determining that relationship. Brilliant white forms a visual target that attracts the eye. Paradoxically, is the most intrusive colour. Natural materials, like nature itself, tend to be richly textured and subtly coloured. Widely use of industrial products is leading to a chromatic impoverishment on the urbanscape. The future of white is going through a change in its conception as decorative element, until it is turned to project foundation thanks to its qualities of tonal gradation, contrast, spatial expansion and composition of scales and forms.

Full Text Available En este artículo desarrollo el uso de la obra cinematográfica en Latinoamérica (durante los años sesenta como instrumento ideológico que nos permite abordar la cuestión de la reivindicación de memorias populares. Inserta en un contexto altamente politizado e influida por las discusiones sobre el colonialismo y la teoría sartreana del compromiso, encontramos en la producción cinematográfica de esta región una voluntad de incitar al espectador a través del arte acerca de la creación de una nueva identidad que englobe al pueblo latinoamericano.Estas obras constituyen documentos, testimonios audiovisuales; pero el historiador que los examinará no será, esta vez, únicamente el estudioso, sino el pueblo mismo. La pretensión de estos films será, entonces, convertirse en portavoces de la memoria: el discurso cinematográfico se convierte en narrador de una identidad. Estas películas, que tendrán un tono militante, tomarán a esas “minorías” como protagonistas esenciales del cambio y como sujetos constructores de representaciones frente a las elaboradas por el discurso hegemónico. Las películas, entonces, no son concebidas como acto individual sino como obra colectiva, asumiendo la cosmovisión de grupos que no se conciben fuera de una comunidad. El cine latinoamericano de los sesenta culminó con la idea de que para la elaboración de un objeto artístico aprobado hay que tomar como referente a los paradigmas exitosos de Hollywood, y entendió que la cultura nacional no es un mero elemento de exhibición destinado a inflar la ambición conquistadora eurocentrista.

2016-10-01

To compare intraocular pressure (IOP) measurement using the Goldmann applanation tonometry (GAT) without fluorescein, with fluorescein strips, with fluorescein droplets, and IOP measurement with Tono-Pen Avia (TPA). This was a prospective comparative clinical analysis. It was performed in clinical practice. The study population consisted of 40 volunteer patients, 1 eye per patient. All patients who were 18 years and older having routine ophthalmological examination were eligible to participate. Active corneal abrasions and/or ulcers, previous glaucoma surgery, or prostheses interfering with GAT measurement were excluded. GAT IOP was measured first without fluorescein, then with fluorescein strip, then with fluorescein droplet, and finally with the TPA device. The main outcome measure was central corneal IOP. Mean±SD IOP measurements for GAT without fluorescein, with fluorescein strip, with fluorescein droplet, and for TPA groups were 12.65±3.01, 14.70±2.82, 15.78±2.64, and 16.33±3.08 mm Hg, respectively. Repeated-measures analysis of variance corrected with the Greenhouse-Geisser estimate ([Latin Small Letter Open E]=0.732) showed that measuring technique had a significant effect on IOP measurements (F2.20,85.59=34.66, P<0.001). The pairwise post hoc testing showed statistically significant mean differences (P≤0.001) between all techniques except when GAT with fluorescein droplet was compared with TPA (P=0.222). The Bland-Altman analyses showed 95% limits of agreement maximum potential discrepancies in measurement ranging from 5.89 mm Hg in the GAT with fluorescein strip versus droplet compared with 11.83 mm Hg in the GAT with fluorescein strip versus TPA comparison. IOP measurement technique significantly impacted the values obtained. The ophthalmologist should ensure consistent measurement technique to minimize variability when following patients.

Case history of natural analogue research on sandstone type uranium occurrences, Japan

International Nuclear Information System (INIS)

Sakamaki, Y.; Kanai, Y.

1991-01-01

Previous fundamental studies on the ore genesis of uranium occurrences chiefly in Cenozoic sandstone formations in Japan, have been re-examined as the case history on natural analogue of radionuclides in high-level radioactive wastes (HLRW). Two principal mode of occurrences have been distinguished among Cenozoic uranium localities in Japan. In the Setouchi (Inland Sea) subregion, hot-spots are found in lacustrine to shallow sea facies of calm environment, corresponding to the first stage of formation of tectonic basins. As observed in Ningyo-toge and Tono area, stratabound ore bodies are generally arranged into paleo-channels. Another type of sporadic uranium indications are found within collapse basins in the 'Green-tuff' subregion, where intense volcanisms and block movements had been taken places throughout Middle miocene age. Well-developed fractures were to be favorable paths for uraniferous groundwater, as well as the suitable site for deposition of uranium. In both cases, the source material of uranium is granitic basement. Under oxidizing environment, uranium anomalies have been occasionally detected in surface- or fracture waters which passing through decomposed granite. In contrast to the behavior of uranium, one of the adequate analogues for mobile nuclides, thorium and REE are relatively immobile even under the same geologic and geochemical circumstances. In ore horizon, where reducing condition has still been kept, geochronological age of tetravalent uranium mineral is in concordance with the age of the host rock. Analysis of structural control shows that the principal factors for uranium concentration are the layout of redox front related to paleo-water tables. 234U/238U disequilibrium method has been proved to be the powerful tool for detecting mobility of uranium in the host rock throughout diagenesis and weathering process. The result of field and laboratory works on this is reported as an example. (author)

Full Text Available Em Moçambique o Currículo Local permite conhecer a realidade próxima do aluno. A formação de professores de Geografia inclui agora a preocupação pelo conhecimento da influência dos fenômenos locais e externos na modificação da paisagem ao redor do aluno. Na Universidade Pedagógica, a formação de professores de Geografia havia-se desligado da realidade, sendo o ensino monótono e muito teórico. A localização da Delegação de Gaza numa área em constante mutação paisagística trouxe outra dinâmica na formação docente, passando a paisagem a ser um objecto de análise, permitindo que o futuro professor apreenda que é necessário romper com a geografia da sala de aulas. O estudante aprende a visualizar que as paisagens são construídas a partir das dinâmicas sociais, não existindo uma sociedade fora da natureza e que os fenômenos são localizados temporal e territorialmente no local onde ocorrem, tendo e recebendo influências de outros lugares e doutros períodos. O contato direto com a paisagem permite a utilização da linguagem cartográfica como metodologia importante para a construção do conhecimento geográfico. Neste trabalho mostra-se como é que a mutação da paisagem é utilizada no processo de ensino e aprendizagem no Curso de Geografia da Universidade Pedagógica, Delegação de Gaza.

Full Text Available São estudados os mecanismos psíquicos que se desenvolvem em agrupamentos humanos e a sua utilização para fins terapêuticos, sendo focalizado o fenômeno da interação como o dinamismo básico dessas reações. O autor compara a forma pela qual encara o grupo com as idéias de Bion, Moreno e Sullivan, encarando a hipótese de que os sentimentos de amor e hostilidade se manifestem em função do bom ou do mau funcionamento dos contactos primários que caracterizam a dependência. O autor comenta resultados que obteve usando o psicodrama, mediante o qual estudou reações emocionais de inveja, ódio, agressividade e amor. O autor analisa as técnicas de Slavson e Pratt baseando-se nos dinamismos inerentes ao grupo e refere os estudos de Beukemkamp para a compreensão do fenômeno transferenciai que, no grupo, tem características próprias. As diferenças entre a terapia de grupo e a individual são apontadas, sendo a contra-transferência considerada como elemento construtivo. Pensa o autor que o aspecto dramático vivenciado pelo grupo ou por um dos seus componentes tem alto valor, pois engloba a verbalização, os componentes emocionais e os componentes posturais. O tono emocional vivenciado pelo grupo é mais intenso e opressivo que o que é despertado na terapêutica individual, o que é explicável pela somação de efeitos provocada pela reação circular. Segundo o autor, a Psicoterapia de Grupo e a Psicoterapia Individual não se opõem, mas se completam.

Study on groundwater flow system in a sedimentary rock area. Case study for the Yoro river basin, Chiba Prefecture

In the safety assessment for a geological disposal of long-lived radioactive waste such as high-level radioactive waste and TRU waste etc, it is important to estimate radionuclide migration to human society associated with groundwater flow. Groundwater flow systems for many domestic areas including Tono Mine, Kamaishi Mine and Horonobe district have been studied, but deep groundwater flow circumstances, and mixing between deep groundwater and shallow groundwater flow system are not well understood. Japan Atomic Energy Agency (JAEA) has started to investigate a sedimentary rock area in the Yoro river basin, in Chiba Prefecture, where the topographic and geological features are relatively simple for mathematical modeling, and hydraulic data as well as data from river and well water are available. Hydro-chemical conditions of the regional groundwater were discussed based on temperature, chemical compositions, isotopic ratios of hydrogen and oxygen, and the isotopic age of radioactive carbon for water samples collected from wells, rivers and springs in the Yoro river basin. It was found that the groundwater system in this basin consists of types of water: Ca-HCO 3 type water, Na-HCO 3 type water and NaCl type water. The Ca-HCO 3 type water is meteoric water cultivated several thousand years or after, the Na-HCO 3 type water is meteoric water cultivated under cold climates several to twenty thousand years ago. The NaCl type water is fossil brine water formed twenty thousand years ago. It was also observed that the Na-HCO 3 type water upwelled at the surface originates from GL-200m to -400m. This observation indicates that the Na-HCO 3 type water upwelled through the Ca-HCO 3 type water area with the both waters partially mixed. (author)

Por la forma, por el contenido, y por la participación del espectador en la puesta en escena del acontecimiento poiético y por la morfología del texto. Recogiendo la pregunta de Hölderlin “Para qué poetas en tiempos de penuria”, la obra establece un dialogo intertextual y transemiótico con ese cuestionamiento a través de esferas rítmicas y de sentidos expresados en 42 textos diseminados a través de enlaces y vínculos que permiten la multidireccionalidad y la libertad de orden de lectura para el espectador. La propuesta brevemente sintetizada asume un propósito ineludible de abordar, eficazmente, los retos de la actual cibercultura, para mostrar, desde la poesía en una clara filiación con la poética mesoamericana (en términos de temporalidades, ritmos y tonos, dada la estructura de este aparato de poesía, los paisajes del desastre de la actual civilización occidental, hija de la razón instrumental que transformó todas las esferas de lo humano  y que, por lo tanto, obliga a tomar posiciones, en este caso, desde la creación estética critico, sin desechar ni olvidar la génesis originaria de todo quehacer poético.

Full Text Available Este artículo se dedica a la identificación numérica confiable y eficiente de los parámetros que definen la función de flujo y el coeficiente de difusión en una ecuación diferencial parcial de tipo parabólico fuertemente degenerada que es la base de un modelo matemático para procesos de sedimentación-consolidación. Para esta ecuación, el problema de valor inicial con valores en la frontera (IBVP en el que el flujo es nulo, describe el asentamiento de una suspensión en una columna. Los parámetros para un material dado se estiman con base en repetidas soluciones numéricas del problema directo (IBVP con una variación sistemática de los parámetros del modelo, con el objeto de minimizar sucesivamente un funcional de costo que mide la distancia entre una observación dependiente de tiempo y la correspondiente solución numérica. En este artículo se destacan dos aspectos. El primer aspecto es que en el método propuesto para la solución numérica eficiente y acertada del problema directo, se implementa un esquema explícito monótono bien conocido basado en diferencias finitas que usan tres puntos mejorado por molificación discreta. El esquema molificado utiliza una malla de más puntos pero converge con una condición CFL menos restrictiva, lo cual permite usar pasos temporales más grandes. El segundo aspecto es el exhaustivo análisis de sensibilidad y estabilidad de las funciones definidas por parámetros en el modelo y que juegan los papeles de aproximación inicial y dato observado, respectivamente.

Full Text Available El 26 de noviembre de 2009, Aitana, de 3 años, fallecía en Arona (Tenerife. Las causas de su muerte apuntaban, según el informe médico, a la existencia de diversos politraumatismos causados por malos tratos, junto con lesiones vaginales y anales. Diego Pastrana, compañero sentimental de la madre, fue detenido. Explicó ante la Guardia Civil que las heridas eran fruto de un accidente en un parque infantil días antes. Una nota de prensa oficial anunciaba la imputación del joven. Los juicios paralelos mediáticos arrancaron de inmediato. Diego apareció esposado mientras la clase periodística repudiaba los hechos y condenaba al acusado. No faltaron altisonantes declaraciones de repulsa entre las autoridades públicas canarias. Con posterioridad, la autopsia descartó las presuntas –y erróneas– causas del fallecimiento. Diego, víctima de una depresión, fue hospitalizado. Días después, abandonó Canarias. En algún diario, los menos, se realizó examen de conciencia; algunos periodistas se disculparon; poco más. Tanto la perspectiva jurídica como la deontología periodística coinciden al trazar el obligado proceder en la cobertura informativa de esta clase de noticias. Preocupa la facilidad con que un reportero puede sesgar la realidad. Este estudio de caso en diarios españoles permite detectar posibles y probables fallas informativas desde múltiples perspectivas: uso impropio de los géneros periodísticos, insuficiente contraste de las fuentes informativas, estilo impreciso, tono y titulación sensacionalistas, disfunciones en la estructura del mensaje y empleo inadecuado de las imágenes.

Full Text Available A juicio de alguno de los estudiosos que en la actualidad han prestado gran interés a los textos de la época, el Breviario de Festo presenta respecto a los Césares de Aurelio Víctor, el Breviario de Eutropio y el Epitome de Caesaribus la singularidad de que su materia no parte de la misma disposición biográfica evidente en ellos 1. En un reciente trabajo dedicado a este breve texto del s. iv procurábamos poner de relieve la estructura de la obra y las distintas particularidades que definen sus diferentes partes apuntando ciertos elementos que, en contra de las apariencias, dejaban traslucir un claro fondo biográfico dentro de una organización general a primera vista muy alejada de tales intereses. Nuestra pretensión al aproximarnos de nuevo a tan original texto, de nulo valor estilístico pero muy atractivo para la historiografía actual, radica en procurar recoger y subrayar esa serie de notas que, tanto desde el punto de vista estructural como calificando directamente a los personajes, conforman ese tono biográfico que, como decimos, se descubre en la obra. Lo cierto es que la concepción individualista de la historiografía latina, agudizada por las circunstancias históricas de la época imperial y el propio carácter del libro —en un epítome es impensable no sólo ya el estudio de cualquier proceso histórico sino el comentario razonado de causas o consecuencias de cualquier acontecimiento—, eran motivos suficientes para hacer derivar el proyecto inicial de Festo alejándolo de la concepción general que debería haber determinado el carácter de la narración.

Relation between fracture toughness and pressure condition in autoclave molding of GF composite laminates is investigated. Glass/epoxy prepregs are molded under different curing pressures, and UD laminates of [O{sub 8}]T and [O{sub 16}]T are fabricated. The results of the double cantilever beam (DCB) test show that the curing pressure has certain influences on the interlaminar fracture toughness via the change in morphology of matrix resin and fibers between laminae, and via the change in interfacial strength of fiber and matrix. It is also found that the fiber/matrix interfacial strength increases as the curing pressure increases by SEM photographs of the fracture surface in GF UD laminates. 13 refs., 12 figs.

The paper studied output characteristics of photovoltaic modules different in installation conditions on the basis of the energy balance state. In the study, an energy balance equation was constructed for insolation intensity, heat losses from PV surface/back, and output, in order to calculate cell temperatures in each installation condition. A comparative study was made between calculated results and measured data obtained on the top of the school building. The results indicated the following: The thickness of thermal boundary layer became approximately 27mm at insolation intensity of 800 W/m{sup 2}, ambient air temperature of 25degC, and wind velocity of 0.5m/s. When widening air gap from 20mm to 40mm, the cell temperature decreased 4degC, and the output increased 1.6%. In the case of installing photovoltaic modules on the roof considering the relation between the air gap in the heat balance state and the thickness of thermal boundary layer, heat from PV back was released outside the air gap if widening the air gap to more than 30-40mm. The type with a heat insulating material on the panel back decreased in output from other types. 5 refs., 7 figs., 4 tabs.

As a technology to evaluate comfort/discomfort of spaces where the thermal environment is non-uniform and unsteady, simulation by a human thermal system, evaluation technology using thermal mannequins substituting for humans, was developed. For the purpose of working out the evaluation standards using it, an experimental study was conducted, and the FY 1999 results were outlined. In the development of evaluation technology using the human thermal system, it was confirmed that the overall trend accorded with the experimental results, as a result of the improvement so made that the contact thermal environment can be simulated. In the development of evaluation technology of the thermal mannequin, a small thermal mannequin was fabricated. As a result of the evaluation of the non-uniform thermal environment, validity of the equivalent temperature was demonstrated. The results of the use of the small mannequin made the design/fabrication of an adult use mannequin possible. In the study to elucidate thermal susceptibility of each part of the human body, an experiment was carried out using an examinee in the uniform and steady environment, and the results were studied of the experiment using the aged examinee on validity of PMV by ISO7730.

Full Text Available This article discusses the philosophical significance of Leo Tolstoy for european modernity, in dialogue with a number of writers and authors that provide an alternative way of thinking confronted to the hegemonic ideas on how the modern conscioussnes was born. The authors addressed here cover a large time span, ranging from the sixteenth to the twentieth century: Thomas Müntzer, Jean-Paul and Carlo Michelstaedter. The hypothesis of this essay argues that european Modernity was strongly influenced by new forms of religious experience that helped to extend across the continent a rupturistic sense of consummation of historical time. The primary aim of this paper is to show the role that certain apocalyptic tone played in Tolstoi’s late work, a tone highly syntomatic of the deep crisis experienced in the religious-political sphere at the beginnig of the twentieth century.

Este artículo analiza cuál es el puesto de León Tolstói en la Modernidad a través de un diálogo con una serie de autores que representan una alternativa al discurso hegemónico en torno a la constitución de la conciencia moderna. Los autores elegidos son representativos de un gran arco temporal que va del siglo XVI hasta el XX: Thomas Müntzer, Jean Paul y Carlo Michelstaedter. La hipótesis del artículo defiende que la Modernidad política quedó fuertemente marcada por formas inéditas de experiencia religiosa que ayudaron a extender por todo el continente una nueva idea de la consumación del tiempo histórico. El argumento principal de este ensayo se dirige a demostrar que la obra de Tolstói participa de un cierto tono apocalíptico que resulta muy sintomático de las fracturas políticas de la modernidad así como de las crisis de la conciencia histórica.

Una estirpe transfeminista (2014. De nuevo, Itziar Ziga nos sorprende con su tono irreverente y su escritura directa. En esta ocasión, la autora recupera las biografías de ocho mujeres que aunque fueron claves en el desarrollo del movimiento feminista, han sido generalmente olvidadas e incluso minusvaloradas dentro de las propias filas del movimiento por la igualdad. De este modo, Ziga nos introduce en las perspectivas de las minorías, las obreras, las lesbianas, las negras, las chicanas, las putas, las transexuales… todos aquellos grupos que aún luchan por derrocar la noción dominante del sujeto del feminismo, así como ampliar su sentido. A través de su obra, así como de su trayectoria y comprometido activismo, Ziga pone en jaque al “Feminismo del Gran Poder”, como ella misma denomina. Sus palabras nos recuerdan que la lucha feminista no ha sido homogénea, sino que ha estado protagonizada a lo largo de las décadas por mujeres diversas, por grupos dispares que no se corresponden con el modelo de mujer blanca, occidental y heterosexual que parece ostentar el monopolio del discurso feminista en nuestra sociedad. En este sentido y con el objetivo de ampliar dicha noción, la selección de las biografías que aparecen en la obra se basa, según Ziga, en un aspecto común que une a todas las mujeres estudiadas, esto es, el estigma y la rebeldía: “todas fueron, son y serán mujeres de acción a las que les persigue cierto malditismo y que nunca trataron de erigirse como líderes”.

Full Text Available Monitoring intraocular pressure (IOP is essential for pediatric cataract treatment but always difficult due to lack of cooperation in young children. We present the baseline characteristics and the first-year results of a long-term prospective cohort study, which are aimed to determine the relationship of the incidence of ocular hypertension (OH in children after cataract surgery during the first-year period and the risk of developing late-onset glaucoma. Children were included with the following criteria: they were ≤10 years old and scheduled to undergo cataract surgery with/without intraocular lens implantation; they were compliant with our follow-up protocol, which included monitoring IOP using a Tono-Pen under sedation or anesthesia. Incidence of OH, peak OH value, OH onset time and OH duration within a 12-month period following surgery were measured. In brief, 206 patients (379 eyes were included and OH developed in 66 of 379 (17.4% eyes. The mean follow-up period was 14.0±3.2 months (median, 12 months; range, 10-16 months. Moreover, 33 of 196 (16.8% aphakic eyes and 33 of 183 (18.0% IOL eyes were diagnosed with OH. The peak OH onset times were at 1-week (34/66, 51.5% and 1-month (14/66, 21.2% appointments postsurgery. The peak IOP value in the OH eyes was 29.9±7.5 mmHg (median, 29 mmHg; range, 21-48 mmHg. The duration of OH was 30.9±31.2 days (median, 30 days; range, 3-150 days. OH recurred in 13 eyes with a history of OH diagnosed within 1 month postsurgery (13/54, 24.1%, which needed temporary or long term use of antiglaucoma medications. In conclusion, the incidence of OH in children after cataract surgery was 17.4% during the first-year period. Children who have suffered elevated IOP in the first year after cataract surgery should be followed closely to determine if there is an increased risk of developing late-onset glaucoma.

Los niños con ambigüedad sexual requieren un diagnóstico, una orientación y tratamiento adecuados en edad temprana. Es importante lograr un diagnóstico definitivo, establecer un plan de tratamiento apropiado, informar sobre el pronóstico participativo y comunicar prudentemente los riesgos precisos de las complicaciones.

En algunos casos es conveniente conformar un equipo de especialistas para resolver estas conductas de manera oportuna y eficiente. Al pediatra le corresponde la evaluación del diagnóstico, la coordinación del equipo de especialistas, ayudar a la familia para entender las condiciones médicas del niño y mantener una comunicación amplia entre la familia y los miembros del equipo de orientación. En la sala de nacimiento no es conveniente asignarle un género al niño que ha nacido con genitales ambiguos; debe referirse como a “su bebé”.

A los padres se les debe demostrar el defecto y explicarles que en el feto las estructuras primordiales del sexo son las mismas y que la evolución de la diferencia sexual puede ser normal o existir desarrollo incompleto o exagerado de los genitales externos, los cuales son posibles de corregir. Animar a los padres para que no se le dé nombre, ni se registre el bebé hasta que se defina el sexo de crianza. Cada niño requiere una atención individual, especialmente un cuidadoso examen físico, estudios de laboratorio y prodigarle sentimientos paternos. El tono emocional de los profesionales de la salud para transmitir esta información puede conducir a una influencia valiosa sobre el concepto de los padres en relación con el desarrollo normal de los genitales.

To evaluate the long-term results and complications of Ahmed glaucoma valve (AGV) implantation in a cohort of Egyptian patients. A retrospective study of 124 eyes of 99 patients with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 5y was performed. All patients underwent complete ophthalmic examination and intraocular pressure (IOP) measurement before surgery and at 1d, weekly for the 1 st month, 3, 6mo, and 1y after surgery and yearly afterward for 5y. IOP was measured by Goldmann applanation tonometry and/or Tono-Pen. Complications and the number of anti-glaucoma medications needed were recorded. Success was defined as IOP less than 21 mm Hg with or without anti-glaucoma medication and without additional glaucoma surgery. Mean age was 23.1±19.9y. All eyes had at least one prior glaucoma surgery. IOP was reduced from a mean of 37.2±6.8 to 19.2±5.2 mm Hg after 5y follow-up with a reduced number of medications from 2.64±0.59 to 1.81±0.4. Complete and qualified success rates were 31.5% and 46.0% respectively at the end of follow-up. The most common complications were encapsulated cyst formation in 51 eyes (41.1%), complicated cataract in 9 eyes (7.25%), recessed tube in 8 eyes (6.45%), tube exposure in 6 eyes (4.8%) and corneal touch in 6 eyes (4.8%). Other complications included extruded AGV, endophthalmitis and persistent hypotony. Each of them was recorded in only 2 eyes (1.6%). Although refractory glaucoma is a difficult problem to manage, AGV is effective and relatively safe procedure in treating refractory glaucoma in Egyptian patients with long-term follow-up. Encapsulated cyst formation was the most common complication, which limits successful IOP control after AGV implantation. However, effective complications management can improve the rate of success.

Full Text Available Durante años, en lo que respecta a la guerra fría de Asia oriental y la política exterior china, los estudiosos se han centrado más en la confrontación entre China y los EE.UU. o en las difíciles relaciones chino-soviéticas, pero ignoraron la política de China hacia Japón. En realidad, de forma distinta a línea dura hacia los Estados Unidos, la política China hacia Japón durante la guerra fría fue en gran parte flexible y suave, que se muestra normalmente en su Diplomacia Popular basado en contactos no-gubernamentales. Este trabajo no sólo analiza los orígenes y desarrollo de este nuevo enfoque diplomático, pero también explora su impacto en Japón y en la alianza de seguridad Estados Unidos-Japón. Según fuentes chinas, americanas, japonesas y de los documentos disponibles recientemente, se argumenta que la Diplomacia Popular, de tono suave y una gran flexibilidad, de hecho, minaba la alianza de Estados Unidos y Japón durante la guerra fría.__________ABSTRACT:For years, in regard to the East Asia cold war and the Chinese foreign policy, scholars have focused more on the Sino-American confrontation or tough Sino-Soviet relations but ignored China's policy toward Japan. Actually, different from its tough policy toward the United States, the Chinese Japan policy during the cold war was largely flexible and soft, which was typically shown in its People's Diplomacy with emphasis on non-governmental contacts. This paper not only discusses the origins and development of this new diplomatic approach but also explores its impacts on Japan and the US-Japan security alliance. Based on Chinese, American, and Japanese sources recently available, it argues that the People's Diplomacy, with its soft tone and great flexibility, effectively undermined the US-Japan cold war security alliance.

Full Text Available Purpose: Swimming goggles increase the intraocular pressure (IOP via the periorbital frame pressure and suction effect. In comparison, diving masks have a larger frame rim and incorporate the nose. The exact effect(s of diving masks on IOP is unknown. This study evaluates the influence of diving masks on IOP in normal, healthy subjects. Methods: Tonometry was performed in both eyes of all subjects with an AVIA®Tono-Pen by a single investigator. Measurements were taken at baseline without the diving mask and with the subjects wearing a small-volume, double-window diving mask, but with the mask lenses removed. Two IOP readings in each eye were measured, and an additional reading was measured if the difference between the initial 2 was ≥2 mm Hg. Central corneal thickness (CCT was also measured in each eye, using a contact pachymeter (OcuScan®Alcon. Results: Forty eyes of 20 healthy volunteers (age 29.7 ± 9.3 years; range 21–52 were included. The mean CCT was 544.4 ± 43.5 µm. The mean IOP before the diving mask was worn had been 17.23 ± 2.18 mm Hg (n = 40. The IOP decreased by 0.43 mm Hg (p < 0.05 to 16.80 ± 2.57 mm Hg after the diving mask had been put on. There was no correlation between IOP change and age (r = 0.143, p = 0.337, gender (r = –0.174, p = 0.283 or CCT (r = –0.123, p = 0.445. Conclusion: There was no increase in IOP after the diving mask had been worn. A small but statistically significant decrease in IOP was observed. This study demonstrates that unlike swimming goggles, the strap tension and frame pressure on the periorbital tissue from a diving mask does not increase IOP. Diving masks may be a suitable alternative to swimming goggles for patients with advanced glaucoma or glaucoma filtration surgery.

In order to establish the scientific and technical basis for geological disposal of technology, Japan Atomic Energy Agency (JAEA) is pursuing the geoscientific research project namely the Mizunami Underground Research Laboratory (MIU) in the crystalline rock environment at Tono Geoscience Center (TGC). In the MIU Project, geoscientific research is being carried out in three overlapping phases; Surface-based Investigation Phase (Phase I: FY1996 - 2004), Construction Phase (Phase II: FY2004- in progress) and Operation Phase (Phase III: FY2010- in progress). In the rock mechanical investigations at the Phase II, the research aims at “Characterization of geological environment in the Excavation Disturbed Zone (EDZ)” from the viewpoint of safety assessment. For the research, the specific information of the EDZ such as (1) size and structures, (2) petrophysical/geomechanical properties, and (3) stress state are required. The research also aims at “Characterization of geomechanical stability around tunnel” from the viewpoint of design and construction of underground facilities. For the research, the specific information such as (4) local stress regime, (5) spatial variability of petrophysical/geomechanical properties of rocks, and (6) distribution of discontinuities intersecting underground tunnels are required. The measurement system for rock mass behavior has been manufactured and set for groundwater recovery experiment in the Phase III. This report presents the results of following rock mechanical investigations conducted in FY 2013. In-situ stress measurements using Compact Conical-ended Borehole Overcoring Technique were performed at the - 500m stage. Measurement system for rock mass displacement using optical fiber was installed at the - 500m stage as part of the groundwater recovery experiment. Study on the modeling based on equivalent continuum model was continued. Phenomenological study and theoretical study on long-term behavior of crystalline rock were

Full Text Available A pesar de los grandes avances en la cardiología en el siglo XX y XXI, la insuficiencia cardiaca sigue suponiendo la principal causa de hospitalización en las personas ancianas y presentando un pronóstico ominoso. Además, a pesar de los múltiples estudios sobre nuevas dianas farmacológicas, apenas hemos avanzado en el campo del tratamiento, tal vez porque aún existen lagunas en su fisiopatología. No debemos olvidar que la insuficiencia cardiaca es un compendio de signos y síntomas que engloban múltiples órganos y sistemas.  Mucho se está investigando sobre la relación entre riñón y corazón en forma de síndrome cardiorrenal.  Algo cada vez más en boga es el papel del abdomen en la disfunción orgánica de la insuficiencia cardiaca. En ese sentido, el sistema venoso contiene el 70% del volumen sanguíneo, siendo almacenado en su mayor parte dentro de las vísceras abdominales. Un aumento del tono simpático supone aumento intenso del retorno venoso tan importante como para  aumentar las presiones de llenado y justificar una descompensación cardiaca. La congestión sistémica determina un aumento en la presión intraabdominal que está correlacionada con la disfunción renal en la insuficiencia cardiaca avanzada. La hipoperfusión tisular intestinal supone microtraslocación bacteriana promoviendo el status proinflamatorio típico de este síndrome. La visión holística e integrada de la insuficiencia cardiaca puede suponer un avance tanto en la estratificación del riesgo como en las estrategias terapéuticas. Grandes pasos se están dando en este sentido con estudios sobre la ultrafiltración, paracentesis, diálisis peritoneal, suero hipertónico o fármacos adsorbentes del sodio.

Full Text Available The films of Agnès Jaoui, a French filmmaker and actress, take an ironic and incisive view of the contemporary French bourgeoisie. Under the guise of dramatic comedies, her films offer polyphonic narratives underlining the difficulties of human relationships, the hypocrisies and the paradoxes of Western societies, as well as constituting a reflection upon identity discourses in present-day France. Jaoui’s biography is also closely linked to music, which comes accross in her films; and music becomes a fundamental element in the plot and a crucial means of expression. This paper analyses all these building blocks and their relation to the reality of France in the following films: Le goût des autres (2000, Comme une image (2004, and Parlez-moi de la pluie (2008.

El cine de la directora y actriz francesa Agnès Jaoui hace un retrato de la burguesía contemporánea del contexto francés en un tono mordaz e irónico. Bajo la apariencia de comedias dramáticas, sus películas plantean narrativas corales que sacan a la luz la dificultad de las relaciones humanas, las hipocresías y las paradojas de la sociedad occidental, al tiempo que son una reflexión sobre los discursos identitarios de la Francia actual. Además, la biografía de Jaoui presenta una estrecha relación con la música que se ve plasmada en sus películas, convirtiéndose en un factor fundamental de la trama y en un medio expresivo de primer orden en sus producciones. Este artículo aborda el estudio de todos estos elementos constructivos y su relación con la realidad francesa en los largometrajes Le goût des autres (Para todos los gustos, 2000, Comme une image (Como una imagen, 2004, y Parlez-moi de la pluie (Háblame de la lluvia, 2008.

Full Text Available AIM: To evaluate the long-term results and complications of Ahmed glaucoma valve (AGV implantation in a cohort of Egyptian patients. METHODS: A retrospective study of 124 eyes of 99 patients with refractory glaucoma who underwent AGV implantation and had a minimum follow-up of 5y was performed. All patients underwent complete ophthalmic examination and intraocular pressure (IOP measurement before surgery and at 1d, weekly for the 1st month, 3, 6mo, and 1y after surgery and yearly afterward for 5y. IOP was measured by Goldmann applanation tonometry and/or Tono-Pen. Complications and the number of anti-glaucoma medications needed were recorded. Success was defined as IOP less than 21 mm Hg with or without anti-glaucoma medication and without additional glaucoma surgery. RESULTS: Mean age was 23.1±19.9y. All eyes had at least one prior glaucoma surgery. IOP was reduced from a mean of 37.2±6.8 to 19.2±5.2 mm Hg after 5y follow-up with a reduced number of medications from 2.64±0.59 to 1.81±0.4. Complete and qualified success rates were 31.5% and 46.0% respectively at the end of follow-up. The most common complications were encapsulated cyst formation in 51 eyes (41.1%, complicated cataract in 9 eyes (7.25%, recessed tube in 8 eyes (6.45%, tube exposure in 6 eyes (4.8% and corneal touch in 6 eyes (4.8%. Other complications included extruded AGV, endophthalmitis and persistent hypotony. Each of them was recorded in only 2 eyes (1.6%. CONCLUSION: Although refractory glaucoma is a difficult problem to manage, AGV is effective and relatively safe procedure in treating refractory glaucoma in Egyptian patients with long-term follow-up. Encapsulated cyst formation was the most common complication, which limits successful IOP control after AGV implantation. However, effective complications management can improve the rate of success.

Full Text Available The fascist foreign politics was characterized by an aggressive tone of protest, which aspired to involve all social and economic forces of the country in an imperial-minded revisionist project. Colonies of emigrants were seen as a matter of proselytizing in the times of the conquest of the power, as speakers of the new domestic and foreign in the years of regime consolidation and as the diffusing avant-gardes of an expansionist project of ideological content in his totalitarian phase. The essential instrument to address this politics of fascistization of the emigrants were the Fasci Italiani all'Estero, whose history went from the initial claim of autonomy at the beginning of the twenties to their control in the context of the institutionalization of the totalitarian State during the decade of the thirties and to their decline with the intervention of Italy in the Second World War. | La política exterior del fascismo se caracterizó por un tono agresivamente reivindicativo, que aspiraba a implicar a todas las fuerzas sociales y económicas del país en un proyecto revisionista con vocación imperial.

El instrumento esencial para abordar esta política de fascistización de los emigrantes fueron los Fasci Italiani all’Estero, cuya historia pasó de la inicial reivindicación de autonomía a inicio de los años veinte a su control en el marco de la institucionalización del Estado totalitario durante la década de los treinta y a su declive con la intervención de Italia en la guerra mundial.

Full Text Available Chicken egg yolks generally owe their color to yellow carotenoids. The addition of synthetic red pigments allows changes in color, from the original yellow to red hues which may be more appealing to consumers in certain markets.Our aim has been to test whether ground crayfish shells, which are a rich and natural source of astaxanthin, produce detectable changes in the coloration of egg yolks through the accumulation of this carotenoid. Laying hens were fed with a commercial feed mixed with crayfish powder and the carotenoid profiles of the yolks in the eggs laid during the trial were monitored by HPLC. The analyses showed a progressive increase in the astaxanthin concentration in the egg yolks, reaching similar levels to those obtained for the rest of present carotenoid pigments.La yema de huevo de gallina debe su coloración a la presencia de carotenoides de tonalidad amarilla. La adición de colorantes sintéticos de tonalidades rojas permite modificar e incrementar la coloración de la yema desde el amarillo original a tonos rojos que pueden ser demandados en ciertos mercados según las preferencias del consumidor. El objetivo del trabajo fue probar si un triturado obtenido a partir de caparazones de cangrejo, que es una fuente natural y rica en astaxanteno, produce cambios detectables en la coloración de la yema de huevo por la acumulación de dicho carotenoide. Las gallinas ponedoras se alimentaron con un pienso comercial al que se adicionó triturado de caparazón de cangrejo. Se realizó un seguimiento de los cambios en la composición carotenoide (mediante HPLC de la yema de los huevos puestos durante el periodo de alimentación suplementada. Los análisis mostraron una progresiva incorporación de astaxanteno que alcanzó niveles similares al resto de carotenoides presentes inicialmente en la yema.

Full Text Available The objective of this study was to measure the intraocular pressure (IOP and tear production before and after topical anaesthesia in healthy chinchillas (Chinchilla lanigera. Thirteen healthy non-sedated chinchillas (eight males and five females were used in this study. The tear production was measured by the novel endodontic paper point tear test (PPTT using Roeko Colour No. 30 Paper points. Following the PPTT, one drop of 0.4 % oxybuprokainium chloride was added to the eye to anaesthetise the cornea and the IOP was measured using the Tono-Pen Avia®Vet. Excess anaesthetic was removed from the conjunctival fornix using a sterile cotton tipped applicator and the PPTT II was performed. The PPTT I and II were measured in 26 eyes, mean ± standard deviations (SD were 7.98 ± 1.95 mm.min−1, and 9.71 ± 3.52 mm.min−1 respectively. The IOP was measured in 20 eyes, and the mean ± SD was 28.52 ± 12.48 mmHg (35.50 ± 9.31 mmHg in males and 21.53 ± 11.57 mmHg in females. There was no significant difference in the PPTT results between the left and right eyes or between the male and female groups. The males were found to have a significantly higher IOP than females and the PPTT II was significantly greater than the PPTT I. The PPTT test proved to be effective, easy to use, and reliable, causing little apparent discomfort to the chinchillas and could prove to be a much more effective tool than the Schirmer tear test for the evaluation of the tear production in animals with small eyes and/or low aqueous tear production. The mean intraocular pressure proved to be much higher in this population of chinchillas than those previously studied and so further investigation is warranted before a reliable reference range may be produced.

Full Text Available Desde sus primeras manifestaciones hace más de un siglo, el cómic se ha ido consolidando como un género popular sobretodo dirigido a un lector juvenil. Su evidente atractivo entre los lectores ha hecho que algunos padres, educadores y profesionales del ámbito de la promoción de la lectura se plantearan el por qué de dicha afición, llegando a conclusiones erróneas como la creencia de que se trata de una lectura menor, dirigida esencialmente a la pura distracción de quien los lee. El manga, en concreto, es el género dentro del cómic que más se consume en occidente. Se ha convertido en un fructífero producto de mercado que deriva en videojuegos, series de televisión, películas de cine… Su gran acogida entre el público infantil y juvenil preocupa a mediadores por la supuesta carga violenta y sexual y la baja calidad literaria de sus obras. El presente propuesta tratará de deshacer algunos tópicos en relación con la concepción errónea la historieta nipona, a partir del estudio de un corpus de obras creadas por autores japoneses y europeos que quieren aportar un cómic de calidad tanto en su forma como en el contenido, abriendo así las puertas a nuevas investigaciones de gran interés. La Novelle manga es un nuevo género dentro del cómic nipón que aúna las estrategias comunicativas más destacables de las novelas gráficas japonesas, el valor estético del cómic francés y la sencillez y el tono de las películas de cine francés dentro de la Nouvelle Vague para crear un cómic que narra historias cotidianas de gran valor literario y estético, muy recomendable para lectores juveniles y adultos.

Full Text Available La apariencia de los poros de la piel normalmente es causada por glándulas sebáceas hiperactivas, sin embargo, en los últimos años se ha reportado que además se ve afectada por diversas enfermedades, entre ellas la diabetes [1], obesidad [2] o cáncer [3]. Generalmente los principales factores que contribuyen a la dilatación de los poros son la edad, género, acné, la exposición crónica al sol o la predispocisión genética. El desarrollo de un método no invasivo que permita conocer las condiciones de la piel, ayudara a relacionar los factores que determinan el tamaño del poro de la piel. En este trabajo se pretende caracterizar por medio de un modelo computacional y con ayuda de un esquema óptico, el tamaño del poro de la piel. El principio físico consiste en iluminar con leds (543nm el antebrazo de voluntarios, el esparcimiento de luz generado por la piel es colectada en una camara ccd. La captura de imágenes, el procesamiento y el análisis estadístico son parte de la metodología para la obtención de datos. Se propone un modelo matemático que relaciona género, edad, tono de piel y tamaño del poro (calculado estadísticamente en las imágenes colectadas ópticamente. Una base de datos se genera y se utiliza para construir matemáticamente modelos mediante regresión simbólica con optimizacion por enjambre de particulas (PSO y se realiza una comparación por medio de regresión lineal. Algunos indicadores estadísticos como el cuadrado medio de error, error de predicción suma de los cuadrados y porcentaje de variabilidad se utilizan en la comparación. Los resultados indican que el modelo propuesto con el tamaño de los poros de cada individuo puede ayudar a hacer una interpretación objetiva de indicadores de enfermedad que afecten directamente el tamaño del poro en la piel.

The Mizunami Underground Research Laboratory (MIU) is now under construction by Japan Atomic Energy Agency (JAEA) in the Cretaceous Toki granite in the Tono area of central Japan. One of the main goals of the MIU project, which is a broad scientific study of the deep geological environment as a basis of research and development for geological disposal of nuclear wastes, is to establish comprehensive techniques for the investigation, analysis and assessment of the deep geological environment in fractured crystalline rock. For this purpose, a geo-synthesis methodology has been developed and will be tested in a dry run to determine if it produces the data required for repository design and associated integrated safety assessment modelling. Surface-based hydrogeological characterisation, intended to develop conceptual models of the deep geological environment based on an understanding of the undisturbed conditions before excavation of this URL, was carried out in a stepwise manner. This allows field investigations, construction of geological and hydrogeological models and interpretation of resultant groundwater flow simulations to develop in an iterative manner. Investigations have the goal of obtaining information on factors relevant to repository design, associated construction, operational and postclosure safety assessment, evaluation of the practicality of implementation and environmental impact assessment. Such factors include bulk hydraulic conductivity, the locations and properties of water conducting features, direct and indirect indicators of regional and local flow (e.g. based on chemistry or isotopes), etc. Following evaluation of pre-existing site information, field investigations began with fault mapping. This was followed by reflection seismic and vertical seismic profile surveys. In addition, a large programme of investigations was carried out in boreholes, including cross-hole tomography and hydraulic tests. Such input is utilised for the construction

The Mizunami Underground Research Laboratory (MIU) is located in Tono area in Central Japan. It is operated by the Japan Atomic Energy Agency (JAEA) with the main purpose of providing scientific basis for the research and development of technologies needed for deep geological disposal of radioactive waste in fractured crystalline rocks. The current work is focused on the research and experiments in the tunnel located at 500 m depth. The data collected in the tunnel and exploratory boreholes were shared with the participants of the DEvelopment of COupled models and their VALidation against EXperiments (DECOVALEX), an international research and model comparison collaboration. This study describes the development of the fracture model representing granite rocks around the research tunnel. The model domain is 100x150x100m with the main experimental part of the tunnel, Closure Test Drift, located approximately in the center. The major input data were the fracture traces measured on the tunnel walls (total of 2,023 fractures), fractures observed in the horizontal borehole parallel to the tunnel, and the packer tests conducted in this borehole and one vertical borehole located within the modeling domain. 78 fractures (the ones with the inflow) in the tunnel were incorporated in the development of the fracture model. Fracture size was derived from the fracture trace analysis. It was shown that the fracture radius followed lognormal distributions. Fracture transmissivity was estimated from an analytical solution of inflow into the tunnel through an individual fracture and the total measured inflow into the tunnel. 16 fractures were incorporated in the model along the horizontal borehole. The packer test data in the different well intervals were used to estimate the range in fracture transmissivity. A relationship between the fracture transmissivity and fracture radius was developed. The fractures in the tunnel and borehole were used to derive fracture orientation and

Full Text Available The aim of this study was to measure the frequency of hearing loss in a sample of typical public high-school students exposed to recreational noise, and determine associated risk factors. The sample was made up of 214 teenagers from a high-school in Mexico City; subjects were selected randomly per strata. We applied a questionnaire to identify risk factors for hearing loss and performed a battery of audiologic tests consisting of otoscopy, tympanometry, and pure-tone audiometry. The mean age of the sample was 16 ± 1.07 years; 73% were male and 27%, female. Hearing loss was found in 21% of students. The main hearing loss-related risk factor was exposure to recreational noise: frequent attendance at discotheques and pop-music concerts; use of personal stereos; and noise exposure in school workshops. The high frequency of hearing loss in high school students from one Mexico City school (nearly one fifth of the sample was found to be related to noise exposure mainly during recreational activities.El objetivo de este estudio fue medir la frecuencia de alteraciones auditivas en una muestra de escolares de educación media superior expuestos a ruido recreativo y determinar algunos factores de riesgo asociados.

O emprego da armadilha CDC tornou acessivo determinar a fauna local. Treze espécies e um número global de 5.423 indivíduos foram capturados. Os pontos situados no ecótono foram os que apresentaram maiores rendimentos, com destaque para P. intermedius, L. migonei e L. fischeri. Desse modo, os resultados levam acreditar serem portadoras de hábito acrodendrófilo. Por outro lado, quando o resultado global foi agrupado segundo o sexo masculino e feminino, o primeiro foi predominante. A análise da distruição estacional dessas espécies citadas revelou claramente picos de atividades mais elevados, bi e tri-modal, para diferentes estações. Na estação outono, P. intermedius teve atividade quase exclusivamente ao nível do solo. Esta exclusividade praticamente se estendeu aos locais de coleta situados em campo aberto.This paper deals with the investigation on the composition and stratification of the Phebotominae activity developed in patch and clear areas of high agricultural activity. The employment of a CDC light trap proved to be a useful tool in determining the local faune. Thirteen species of sandflies and a total of 5,423 individuals were caught. The catch places situated in the ecotone were the ones in which the results reached their best, being outstanding for Psychodopygus intermedius, Lutzomyia migonei and L. fischeri. Thereby, data lead us to believe they have acrodendrophilous habit. On the other hand, when the global results were gathered according to male and female categories, the first one proved to be predominant. In the analysis of seasonal distribution for the three species cited, it was clear that the high-activity peaks were bi- and tri-modal for different seasons. P. intermedius was almost the exclusive sandfly caught at ground level in the Autumn

Lost functions of the larynx and the trachea may be restored by different means, but none of them is physiologic and patients are left with functional difficulties and self-esteem disorders that alter the quality of their lives.  Transplantation of these organs is an useful alternative but certain basic requirements concerning revascularization, reinnervation and immunosupression should be fulfilled.  The former has been achieved through the knowledge of vascular territories and the advances in surgical techniques.  Difficulties for reinnervation have no yet been thoroughly overcome but tone can be achieved in the vocal folds and functionality may be obtained by manipulation of their position.  Immunosupression is produced with cyclosporine which requirements were determined in experimental models.  The main reason for carrying out these and other transplantations is to improve the quality of life of persons who have suffered the loss of an organ.  A review is presented on important aspects that have to be taken into account when performing these transplantations.

Full Text Available O eucalipto sofre severos danos por cupins durante a implantação das mudas no campo, sendo considerada praga importante da cultura. No ecótono Cerrado/Pantanal não existem estudos anteriores sobre a ocorrência de cupins em plantações de eucalipto. O objetivo foi conhecer a riqueza de cupins, sua distribuição nos tratamentos e a influência do ambiente nas populações de cupins, nos híbridos de eucalipto Eucalyptus grandis x E. camaldulensis e Eucalyptus urophylla x E. grandis com fertirrigação por gotejamento, microaspersão e sequeiro. O delineamento experimental foi o de blocos ao acaso, com 10 tratamentos e quatro repetições. A riqueza de cupins foi associada pela Análise de Correspondência e pela influência climática pela Análise de Componentes Principais. Os cupins foram coletados de março de 2012 a fevereiro de 2013, em 432 parcelas de 4,0 x 2,25 m, em uma área de 3 ha, seguindo o protocolo rápido de coleta, observando-se a serrapilheira, e até 30 cm de profundidade no solo. Obtiveram-se 18 espécies de Termitidae, Rhinotermitidae, Heterotermitinae, Syntermitinae, Apicotermitinae e Nasutitermitinae. Nos tratamentos com gotejamento, houve a maior frequência total, com presença de 18 espécies de cupins nos híbridos, sem associação significativa. A associação entre espécies de cupins e tratamentos constituiu quatro grupos. A precipitação e a umidade relativa do ar influenciaram significativamente na comunidade dos cupins. Portanto, a maior riqueza de espécies ocorreu nos tratamentos com gotejamento. Das espécies consideradas pragas de eucalipto, destacou-se Syntermes molestus, pela sua maior frequência durante as coletas. Ocorreu diferença significativa na distribuição das espécies de cupins associadas aos tratamentos entre os meses de coleta. A riqueza e a distribuição dos cupins são influenciadas ao longo do ano pelos diferentes manejos de irrigação em áreas de cultivo de eucalipto.

This study involves evaluation of uncertainty in hydrogeological modeling and groundwater flow analysis. Three-dimensional groundwater flow in Shobasama site in Tono was analyzed using two continuum models and one discontinuous model. The domain of this study covered area of four kilometers in east-west direction and six kilometers in north-south direction. Moreover, for the purpose of evaluating how uncertainties included in modeling of hydrogeological structure and results of groundwater simulation decreased with progress of investigation research, updating and calibration of the models about several modeling techniques of hydrogeological structure and groundwater flow analysis techniques were carried out, based on the information and knowledge which were newly acquired. The acquired knowledge is as follows. As a result of setting parameters and structures in renewal of the models following to the circumstances by last year, there is no big difference to handling between modeling methods. The model calibration is performed by the method of matching numerical simulation with observation, about the pressure response caused by opening and closing of a packer in MIU-2 borehole. Each analysis technique attains reducing of residual sum of squares of observations and results of numerical simulation by adjusting hydrogeological parameters. However, each model adjusts different parameters as water conductivity, effective porosity, specific storage, and anisotropy. When calibrating models, sometimes it is impossible to explain the phenomena only by adjusting parameters. In such case, another investigation may be required to clarify details of hydrogeological structure more. As a result of comparing research from beginning to this year, the following conclusions are obtained about investigation. (1) The transient hydraulic data are effective means in reducing the uncertainty of hydrogeological structure. (2) Effective porosity for calculating pore water velocity of

This paper describes the distribution of Curie point depth and its characteristics determined from the spectral analysis of magnetic anomaly data in East and Southeast Asia. It also describes relationships between the Curie point depth and the other geophysical information such as topography, heat flow data and tectonics. The Curie point depths are shallower than about 10 km at volcanic and geothermal areas, between 15 and 25 km at island arcs and back arc rifts, deeper than 20 km at continents, and deeper than 30 km at trenches. The Curie point depth (Dc) estimated from the heat flow data can be expressed by Dc=k{theta}c/q where k is thermal conductivity, q is heat flow, and {theta}c is Curie point. Based on the Curie point depths obtained from Curie point depth analysis in the cross section of northeast Japan and the averaged values of heat flow at individual points, they are distributed along a line of k{theta}c=1500[Wm{sup -1}]. Values of k{theta}c are small near the axis of Japan trench and large in the northeast Japan. It is considered that local anomalies can not be grasped from the spectral analysis. 21 refs., 3 figs.

This is a detailed report on a 2-week tour made in May, 1997, as part of the `9th regular interchange with energy-related organizations in Europe,` during which tour visits were paid to energy agencies and institutes of Germany, the Netherlands, Sweden, Denmark, and France, and on-site investigations were conducted. The text describes, taking reference to a rich stock of data it carries, the nature, politics and economy, demand for energy, policy toward new energy, for each of the host countries. In the European countries, with the exception of France, efforts are being exerted to introduce new energy and to enhance its application, renewable energy in particular, in place of atomic power. The expectation they entertain toward new energy is far extensive than that of Japan which retains atomic power generation. Although wind power generation enjoys the overwhelming popularity over others, yet, in Germany and Sweden, it will be difficult for this technology to take the place of atomic power generation completely. As for photovoltaic power generation, not so much is expected from this technology as in Japan because of their climate and weather. 67 figs., 10 tabs.

As one of the environmental problems in sea areas surrounding a very large floating structure (VLFS), change in flow condition is important, and it is one of the factors dominating the prediction of succeeding diffusion and ecosystems. Although a multi-layer model is in wide use for computation of flow condition and diffusion in one inner bay, its applicability should be reexamined because of no consideration of VLFSs. In this study, flow velocity profiles around a barge were then measured through the towing test of a barge in shallow water, and compared with computation results using a multi-layer model. The multi-layer model computed the flow velocity profiles by dividing the flow region to be computed into normal one and that under VLFS, and determined pressures under VLFS by 2-D Poisson`s equation. Slip condition was used as boundary condition at the bottom considering the number of layers under VLFS. Further numerical computation was conducted by 2-D MAC method, in particular, to compare flow around the wake of VLFS with experimental one. Both computation results well agreed with experimental one. 3 refs., 9 figs., 1 tab.

It was intended to elucidate characteristics of distribution of damages caused by an earthquake which occurs directly below an urban area. Therefore, numerical simulation using the pseudo-spectral method was performed on characteristics of seismic wave propagation in non-homogenous media composed of rock beds and sediment beds, and of seismic wave amplitudes on ground surface. The simulation has utilized information on underground structures disclosed by using the latest physical exploration method. The underground structure model assumed a two-dimensional model hypothesizing presence of upper, middle and lower beds in the Osaka bed group on granite, using as reference the information on S-wave velocity underground structure revealed by the microtremor exploration method. With an objective to elucidate characteristics of distribution of collapse ratio in the area from 8-chome, Okamoto, Higashinada Ward, Kobe City to 2-chome of Sakanasaki Minamicho, as damages suffered from the Hyogo-ken Nanbu Earthquake, a simulation has been performed varying the structure model based on the results derived by the microtremor exploration method and the reflection method. As a result, it was shown that the characteristics of the maximum amplitude distribution of displacement of ground surface, velocity and acceleration agree well with those of the collapse ratio distribution, and that the simulation using the pseudo-spectral method is an effective means to analyze the ground surface collapse ratio distribution. 5 refs., 3 figs.

By recent developments of exclusive rotor blade, the efficiency of wind turbine is improved substantially. By measuring pressure on rotor blades of horizontal axis wind turbines rotating in wind tunnels, this report clarified relation between improvement of pressure distribution on main rotor blades by Mie vane and upgrade of wind turbine performance. The results under mentioned have been got by measuring pressure distribution on rotor blades, visualization by tuft, and measuring resistance of Mie vane. (1) The difference of pressure between suction surface and pressure surface on the end of rotor blade increase, and output power of wind turbine improves. (2) Vortex of blade end is inhibited by Mie vane. (3) The reason of reduction on wind turbine performance with Mie vane in aria of high rotating speed ratio is the increase of Mie vane flow resistance.(NEDO)

The relationship between change in resistivity and rainfall was studied by continuously measuring resistivities of fracture zone and stratum boundary along the measuring line of 95m long from the top to bottom of rock slope. The measurement field was located on a hill of 150-200m high at the northern part of Arima-Takatsuki tectonic line. Electrodes of 30m in maximum measuring depth were arranged at 289 points by dipole-dipole method. Resistivity was continuously measured at time intervals of 6 hours. Apparent resistivity was hardly affected by rainfall at points with less infiltration of stormwater from the ground surface, while it decreased by rainfall at points on fracture zone, stratum boundary or bleeding channel. The change rate of apparent resistivity could be approximated with the exponential function of rainfall. In such case, the apparent resistivity under most dried condition at the concerned point should be used as reference maximum apparent resistivity. The change rate of apparent resistivity due to rainfall in fracture zone reflects infiltration of stormwater, suggesting to be useful for disaster prevention of slopes. 5 refs., 6 figs.

The research in 2011 discovered a room with high-quality wall and mosaic decoration, especially on its western wall, which had collapsed over the pavement. It was moved to the laboratories of the University of Granada for consolidation and restoration works. Since previous information on wall paintings from Castulo was scarce, before the restoration took place the paintings were studied, including the characterization of the materials and painting techniques.

Full Text Available Descreve-se a ocorrência de raiva em ovinos na região Central do Rio Grande do Sul em novembro de 2003. Foram afetados dois ovinos de raça mista, um macho de três meses e uma fêmea de 2,5 anos de idade que apresentaram sinais clínicos com evolução de cinco dias e caracterizados por dificuldade de locomoção, tremores musculares, decúbito lateral, convulsões, opistótono e febre. Histologicamente havia mielomeningoencefalite não-supurativa, associada a inclusões eosinofílicas intracitoplasmáticas (corpúsculos de Negri em neurônios nos dois ovinos afetados. Em um ovino em que o gânglio de Gasser foi examinado, havia ganglionite não-supurativa. As lesões concentravam-se predominantemente na substância cinzenta da medula espinhal, no tronco encefálico e no cerebelo. Antígeno viral foi detectado em seções selecionadas de ponte e bulbo submetidas ao teste de imuno-histoquímica utilizando anticorpo policlonal anti-ribonucleoproteína do vírus da raiva. Os casos ocorreram em meio a um surto de raiva bovina transmitida por morcegos e foram considerados, com bases epidemiológicas, como transmitidos da mesma forma, como ocorre na raiva endêmica de bovinos no Rio Grande do Sul.Cases of rabies in sheep occurring in November 2003, in central Rio Grande do Sul state, Brazil, are described. A 3-month-old male, and a 2.5-month-old female sheep were affected. Clinical signs were characterized by abnormal gait, trembling, lateral recumbency, convulsion, opisthotonus, and fever. Histological findings included a non-suppurative myelomeningoencephalitis associated with intracytoplasmic eosinophilic inclusion (Negri bodies in neurons. Lesions were predominantly observed in gray matter of the spinal cord, brainstem and cerebellum. There was non-suppurative Gasserian ganglionitis in one sheep in which this structure was examined.

En ambos casos estuvo entre los vencedores pero por conveniencia e indecisión, los poderes políticos optaron por soluciones academicistas. Al conocer las decisiones definitivas, Le Corbusier y todos sus contactos del Movimiento Moderno orquestaron diversas polémicas ante los medios de comunicación y los gobernantes por entender que el progreso se veía lastrado por el triunfo de propuestas reaccionarias. Mediante el estudio de la correspondencia con personas particulares como Moser, Giedion, Colly o Stonorov, conservada en la Fundación Le Corbusier, se analizan las relaciones y el tono ideológico en torno a aquellas protestas. En esos textos quedan reflejados los principales rasgos que caracterizan la modernidad como su internacionalización, la seguridad en la propia misión, la defensa de lo nuevo o el método dialéctico. SUMMARY When Le Corbusier had already passed the age of forty he confronted two international competitions: the Palais des Nations in Geneva (1926–1931 and the Palace of the Soviets in Moscow (1931–32, with which he attempted to access large state commissions, with greater urban scale, in which to test his ideas about modern architecture and urbanism. In both cases he was among the winners, but through convenience and indecision the political powers opted for solutions from academicians. Upon knowing the final decisions, Le Corbusier and all his contacts in the Modern Movement orchestrated several controversies with the media, and the people in power, to convey that progress seemed burdened by the triumph of reactionary proposals.

Full Text Available Harvest time has been since Upper Antiquity an exceptional occasion in peasant societies, giving rise to festive customs such as duels of improvised poetry in obscene tone and motif. In these duels, precepts of decency were momentarily removed. The historical and comparative research since the fescennini verses of Antiquity, through the pullas of the trovadores de repente of the Golden Age and other satirical genres, allows to link the priapic improvised poetry of the Alpujarra in both reaping and grape harvest contexts to a long popular tradition in which debates of burlesque verses were an entertainment associated with the nexus between fertility of earth and sexuality and with a sense of regeneration that has cathartic laugh. The survival of this burlesque and erotic register among the Alpujarra troubadours in certain festivals, coincidental in dates, spaces and actors with the traditional context of licenses during harvest time, suggests the reusing of these duels of inventiveness, in which participants play recalling a time when

To investigate the potential usage of biological delivery membranes containing mitomycin C (MMC) or 5-fluorouracil (5-FU) in the construction of glaucoma-filtering blebs, and to evaluate their safety and efficacy. Chitosan was selected as the biological membrane carrier to prepare sustained-released membranes. Twelve micrograms of 5-FU or MMC was covalently conjugated onto the membranes by solvent volatilization. Rabbits underwent glaucoma filtration surgery and were randomly allocated into one of the four treatment regimens: glaucoma filtration operation with no implantation of chitosan membrane group (as control), drug-free chitosan membrane implantation group (blank/placebo group), membrane containing 5-FU treatment group (5-FU group), and membrane containing MMC treatment group (MMC group). Each group consisted of 12 rabbits. Intraocular pressure (IOP) was measured and evaluated over a 28-day period follow-up preoperatively, then after surgery on days 1, 3, 5, 7, 14, 21, and 28 by Tono-Pen. The aqueous humor was analyzed in each experimental and control groups at days 4, 6, 8, 10, 12, 14, 16, and 20 after operation. Bleb survival and anterior segment were examined with a slit lamp microscope and photographed simultaneously. Two rabbits from each group were killed on day 28 and eight eye samples obtained for histopathological study. Corneas and lenses were examined by transmission and scanning electron microscopy. Both 5-FU and MMC significantly prolonged bleb survival compared with control groups. The filtering bleb's survival period was significantly more prolonged in the MMC and 5-FU groups (maintained 14 days) than the other two groups (maintained 7 days). Significantly lower IOP was observed within the control, blank, and 5-FU groups after surgery on day 14 compared with that before operation, with F-values of 6.567, 11.426, and 13.467, respectively (P < 0.01). The most significant lower IOP was recorded in the MMC group on day 28 postoperation (F-value 26

Full Text Available Tanto los patrones como el tono de la coloración dorsal y ventral han sido caracteres comúnmente utilizados para el reconocimiento y diferenciación de numerosas especies y subespecies del género de Bufonidae Melanophryniscus. Sin embargo, raramente se han presentado análisis detallados y sistematizados que indiquen la ausencia o la baja frecuencia de polimorfismos en estos caracteres para asegurar que son realmente diagnósticos. Mediante una metodología sistematizada se estableció la validez diagnóstica de estos caracteres para las poblaciones argentinas de Melanophryniscus rubriventris. La información obtenida en este trabajo, sugiere la existencia de poblaciones con variaciones morfológicas distintivas aunque no exclusivas y se propone que las actuales subespecies sean sinonimizadas. Dada la importante variabilidad registrada en los patrones de coloración de ejemplares conservados y de la intensidad de la coloración in vivo en todo el rango de distribución de Melanophryniscus rubriventris, así como la multiplicidad de fuentes de variabilidad que estos caracteres pueden expresar, se sugiere que el uso de la coloración como carácter diagnóstico único para la delimitación de especies sea utilizado con cierta precaución o empleando una metodología de muestreo rigurosa que contemple la edad, el sexo y la mayor cantidad posible de poblaciones en todo el rango de distribución del grupo a investigar. Both, patterns and hue of dorsal and ventral coloration were commonly utilized in species and subspecies recognition in the genus of Bufonidae Melanophryniscus. However, no detailed and systematized analysis were presented to determine if such characters are truly fixed. I determine the validity of these attributes as truly diagnostic characters in different populations of Melanophryniscus rubriventris of Argentina. The evidence obtained suggest the existence of sets of populations which differ only in trait frequencies and I

Here we report the first seismic monitoring system in active and constant operation for the wave propagation characteristics in tectonic region just above the subducting plate driving the coming catastrophic earthquakes. Developmental works of such a system (ACROSS; acronym for Accurately Controlled, Routinely Operated, Signal System) have been started in 1994 at Nagoya University and since 1996 also at TGC (Tono Geoscience Center) of JAEA promoted by Hyogoken Nanbu Earthquakes (1995 Jan.17, Mj=7.3). The ACROSS is a technology system including theory of signal and data processing based on the brand new concept of measurement methodology of Green function between a signal source and observation site. The works done for first generation system are reported at IWAM04 and in JAEA report (Kumazawa et al.,2007). The Meteorological Research Institute of JMA has started a project of test monitoring of Tokai area in 2004 in corporation with Shizuoka University to realize the practical use of the seismic ACROSS for earthquake prediction researches. The first target was set to Tokai Earthquake not yet to take place. The seismic ACROSS transmitter was designed so as to be appropriate for the sensitive monitoring of the deep active fault zone on the basis of the previous technology elements accumulated so far. The ground coupler (antenna) is a large steel-reinforced concrete block (over 20m3) installed in the basement rocks in order to preserve the stability. Eccentric moment of the rotary transmitter is 82 kgm at maximum, 10 times larger than that of the first generation. Carrier frequency of FM signal for practical use can be from 3.5 to 15 Hz, and the signal phase is accurately controlled by a motor with vector inverter synchronized with GPS clock with a precision of 10-4 radian or better. By referring to the existing structure model in this area (Iidaka et al., 2003), the site of the transmitting station was chosen at Morimachi so as to be appropriate for detecting the

La obesidad está vinculada estrechamente con las principales causas de morbimortalidad y discapacidad. La resistencia insulínica (RI es quizás su consecuencia más temible, ya que de ella se derivan una serie de alteraciones metabólicas y endoteliales relacionadas con el desarrollo de la enfermedad vacular coronaria: la diabetes mellitus, la hipertensión arterial, las dislipidemias y la enfermedad cerebrovascular. En la medida en que aumenta el peso corporal, aumenta la producción de citoquinas y ácidos grasos libres con efectos sobre la insulina, disminuye la sensibilidad a su acción y de ahí derivan alteraciones de la pared y el tono vascular, así como del metabolismo de glúcidos y lípidos, que dan origen a estas consecuencias. Con la presente revisión nos proponemos profundizar en el papel del adipocito como órgano o tejido endocrino, y los mecanismos hasta ahora conocidos que dan origen a las complicaciones clinicometabólicas de la obesidad.Obesity is a serious problem in world health.

Ground-level ozone (O3) is an important pollutant that affects both global climate change and regional air quality, with the latter linked to detrimental effects on both human health and ecosystems. Ozone is not directly emitted in the atmosphere but is formed from chemical reactions involving volatile organic compounds (VOCs), nitrogen oxides (NOx = NO + NO2) and sunlight. The photochemical nature of ozone makes the implementation of reduction strategies challenging and a good understanding of its formation chemistry is fundamental in order to develop efficient strategies of ozone reduction from mitigation measures of primary VOCs and NOx emissions. An instrument for direct measurements of ozone production rates (OPRs) was developed and deployed in the field as part of the IRRONIC (Indiana Radical, Reactivity and Ozone Production Intercomparison) field campaign. The OPR instrument is based on the principle of the previously published MOPS instrument (Measurement of Ozone Production Sensor) but using a different sampling design made of quartz flow tubes and a different Ox (O3 and NO2) conversion-detection scheme composed of an O3-to-NO2 conversion unit and a cavity attenuated phase shift spectroscopy (CAPS) NO2 monitor. Tests performed in the laboratory and in the field, together with model simulations of the radical chemistry occurring inside the flow tubes, were used to assess (i) the reliability of the measurement principle and (ii) potential biases associated with OPR measurements. This publication reports the first field measurements made using this instrument to illustrate its performance. The results showed that a photo-enhanced loss of ozone inside the sampling flow tubes disturbs the measurements. This issue needs to be solved to be able to perform accurate ambient measurements of ozone production rates with the instrument described in this study. However, an attempt was made to investigate the OPR sensitivity to NOx by adding NO inside the instrument

Objective: Metuximab is a specific monoclonal antibody F(ab') fragment targeted to the hepatocellular carcinoma (HCC) associated antigen of HAb18G/CD147. 131 I labeled metuximab has shown to be effective response on HCC in phase I/II trails. To evaluate the feasibility of 131 I-metuximab combined with transarterial chemoembolization (TACE) is the treatment of HCC, the authors estimated the radiation absorbed dose to organs. Methods: 131 I-metuximab (27.75 MBq/kg) and the mixture of anticancer drug and Lipiodol with interval 20 min later were administered to 21 patients with HCC via a transfemoral catheter. The pharmacokinetic and dosimetric data were collected by means of venous blood samples, urine collections, and 4 or 5 γ-scintigraphies (SPECT) over 7 d. The total amount of activity in percent of injected activity (% ID) of main organ and the total body were calculated by regions of interest (ROI). The cumulated activities were determined from integration of the time-% ID curves using the SPSS 12.0 software. Absorbed doses to organ and red marrow were estimated according to the medical internal radiation dose (MIRD) formalism and blood-based marrow estimation with a red marrow-to-blood activity concentration ratio. The tumor- to-no tumor ratio was calculated as well. Results: A mean administered activity was 1.89 GBq per session (range 1.47-2.23 GBq). SPECT scans showed the significant accumulation of the radioconjugate in liver tumor and faint uptake in other organs until 14 d. Organ absorbed dose (n=12): the total absorbed dose to liver, spleen, thyroid, lungs, kidney and total-body was (3.19 ± 1.01), (3.65 ± 2.41), (3.61 ± 2.40), (0.97 ± 0.23), (0.96 ± 0.35) and (0.57 ± 1.55) Gy, with (0.55 ± 0.09) Gy to the red marrow (n=7), respectively. From 2.88 ± 1.11 to 1.64 ± 0.39 were observed in tumor-to-liver ratio at 3 h to 168 h. Conclusion: Internal absorbed dose estimation based on MIRD formalism is not only to establish re- liable dose

For investigating biological effects of a localized SAR (specific absorption rate) deposited in a human body for electromagnetic wave exposure, it is indispensable to graps a temperature-rise inside a human brain including the control center for the body temperature. This paper numerically analyzes a temperature-rise inside an eyeball of our developed realistic head model for 1.5 GHz microwave exposure, using the FD-TD (finite-difference time-domain) method. The computed results are validated in comparison with the data obtained by Taflove and his colleague. In order to examine a quantitative relationship between the localized SAR and temperature-rise, we also obtained a tissue amount over which the localized SAR should be averaged so as to well reflect the temperature-rise distribution inside the eyeball. 15 refs., 9 figs., 3 tabs.

Full Text Available Solid solutions corresponding to the YCoXMn1-XO3 system, x=0.2...0.7 have been studied. The powders were prepared by solid state reaction of the corresponding oxides. Sintered bodies were obtained by firing between 1250 and 1350ºC. The incorporation of 25 at% Co2+ to the yttrium manganite induces the appearance of a perovskite-type phase with orthorhombic symmetry and Space Group Pbnm, which is extended at least up to an amount of x=0.70. Increase of the Co content from x=0.25 to x=0.70 leads to a monotonic decrease of the orthorhombicity factor b/a. Electrical measurements have shown semiconducting behaviour for all the solid solutions with the perovskite-type structure. The room temperature conductivity increases with Co up to x=0.33, and then decreases. The 60/40 Co/Mn composition shows an increase of the electrical conductivity respect to the 50/50 and a correlative decrease of the activation energy. Small polaron hopping mechanism thermally activated controls the conductivity of these ceramics.Se han estudiado las soluciones sólidas correspondientes al sistema YCoXMn1-XO3 con x=0.2...0.7.

Full Text Available El desarrollo del niño está íntimamente ligado a los procesos de maduración del Sistema Nervioso Central (SNC, fundamentalmente en lo que se refiere a las funciones psicomotoras. Dentro de las alteraciones del SNC se encuentra la Parálisis Cerebral (PC, entendida como trastorno del tono postural y del movimiento, secundario a una lesión del cerebro inmaduro. La necesidad de la experiencia sensorial y el ejercicio motor es una premisa básica para el desarrollo infantil típico, haciéndose aún más necesaria en el niño con PC.La estimulación de las funciones motoras y cognitivas, debe darse en el marco de un vínculo de afecto con el niño con PC, a fin de establecer un clima de confianza que permita al niño trabajar junto al psicólogo en pos de su desarrollo. El objetivo del presente trabajo es analizar las implicancias del vínculo afectivo en el desarrollo motor y cognitivo de niños con PC, de entre 4 y 6 años de edad. Metodológicamente los datos son tratados cualitativamente, se trata de un estudio de casos seleccionados de forma intencional: se toman dos pacientes en tratamiento psicológico desde temprana edad, de una institución privada dedicada al abordaje interdisciplinario de las patologías de la infancia. Los pacientes designados presentan diagnóstico de P.C, de distinta complejidad, se comparan los sentimientos de los niños y su psicoterapeuta, durante su interrelación. Se utilizan como instrumentos para el relevamiento de datos, observación de la sesión psicológica y entrevista semidirigida a psicoterapeuta infantil. Entre los resultados se destacan la relación de la vulnerabilidad física y psíquica del niño con PC, siendo la desvitalización anímica, de la que habla Jorge Cantis, mayor en el paciente con diagnóstico de PC grave o severa. En relación al psicoterapeuta, se observa la necesidad de estar atento a sus sentimientos, para no identificarse con los sentimientos del paciente con P.C y/o de su

Full Text Available The mechanical behaviour of a Nb-microalloyed steel under non monotonie conditions has been studied using double hit hot torsion tests involving changes in the twist direction. For strain reversal conditions, a clear mechanical transient has been observed. This transient has been characterized by a steep hardening region just after reversal which takes place up to a stress level near the one reached before reversing, then a region showing a low strain hardening rate and finally, a region extending up to the convergence of monotonie and reversal behaviours. Testing temperatures and strain rates have ranged from 950°C to 1200°C and from 0.01s^-1 to 0.1s^-1, respectively. Applied prestrains before reversal have varied from 0.03 to 0.25 in order to avoid the occurrence of dynamic recrystallization during previous strain. Lastly, some relationships have been established between the deformation conditions and the parameters defining the transient. These parameters depend mainly on the prestrain.

Se ha estudiado el comportamiento mecánico de un acero microaleado con niobio bajo condiciones no monótonas de deformación mediante ensayos de torsión en caliente de doble pasada con cambio de sentido de giro entre la primera y la segunda de ellas. Se ha observado que la inversión de la deformación produce un transitorio en las curvas de fluencia caracterizado por un endurecimiento rápido hasta alcanzar un nivel de tensión menor al que se tenía, justo, antes de aplicar el cambio en el sentido de giro, una etapa de endurecimiento nulo y, finalmente, una región en la que el comportamiento mecánico durante la inversión tiende progresivamente al comportamiento mecánico monótono. Las temperaturas de ensayo se han variado entre 950 °C y 1.200 °C y las velocidades de deformación entre 0,01 y 0,1 s^-1 Las deformaciones previas aplicadas antes de la reversión han estado comprendidas entre 0,03 y 0,25, evit

Full Text Available In order to illustrate the relationships between the biotopes (or phytogeographical zones, arbovirus vectors and vertebrate hosts (including man, and epidemiology, current knowledge on the transmission of Yellow Fever virus in West Africa is reported. A dynamic scheme has been devised to integrate the observed geographical distribution of cases and the timing of their occurrence. Two principal areas, endemicity and epidetnicity, were defined according to the presence or absence of sylvatic monkey-mosquito transmission. The intensity and potential of contacts between humans and vectors depends on the degree of man-made changes in the environment, often increasing the extension of ecotone areas where the mosquitoes are easily biting at the ground level. Prevention and/or control of arbovirus diseases require detailed eco-epidemiological studies to determine: (1 the effective role of each potential vector in each phytogeographical region; (2 the risk factors for the people living in or near areas with a sylvatic transmission cycle; (3 the priorities - vaccination and/or control - for preventing the expansion of natural foci.Para ilustrar as relações existentes entre os biótopos (ou zonas fitogeográficas, os vetores e hospedeiros vertebrados (incluindo o homem de arbovírus e a epidemiologia, o conhecimento atual sobre a transmissão do vírus de febre amarela na África Ocidental é apresentado e discutido.

MF foi administrado, por via oral, em doses únicas de 0,5 e 1,0mg/kg, cada dose para dois ovinos, e em doses subletais repetidas diariamente de 0,1mg/kg/dia, por quatro dias, e 0,2mg/kg/dia por seis dias, cada dose para um ovino. Todos os ovinos que receberam MF morreram, exceto um que recebeu 0,5mg/kg e não mostrou sintomas. A evolução da intoxicação variou de 3min a 33h5min. Clinicamente os animais apresentaram taquicardia, respiração abdominal, tremores musculares, ligeira perda de equilíbrio, por vezes cambaleavam, deitavam e apoiavam a cabeça no flanco. Na fase final, os ovinos caíam em decúbito lateral, esticavam os membros, faziam movimentos de pedalagem, apresentavam opistótono e morriam. O exame ecocardiográfico evidenciou dilatação cardíaca e redução da fração de encurtamento sistólico. A análise dos níveis séricos de uréia e creatinina revelou moderada a acentuada azotemia. MF provocou "morte súbita" em todos os ovinos que mostraram sintomas. À necropsia verificaram-se aurículas e veias jugulares, cavas, ázigos e pulmonares moderadamente ingurgitadas e, em alguns animais, edema pulmonar. O exame histopatológico revelou, em todos os ovinos, leve a acentuada DHV das células epiteliais dos túbulos contornados distais, associada à picnose nuclear. Adicionalmente, verificaram-se discreta vacuolização e, por vezes, necrose de coagulação de hepatócitos. Não encontramos referências a esse tipo peculiar de lesão, exceto das descrições sobre lesões renais associadas à ingestão de PBCMS e de recentes estudos em bovinos intoxicados com MF. Este

Hotspot detection and characterization has played an increasing role in understanding the maintenance and transmission of zoonotic pathogens. Identifying the specific environmental factors (or their correlates) that influence reservoir host abundance help increase understanding of how pathogens are maintained in natural systems and are crucial to identifying disease risk. However, most recent studies are performed at macro-scale and describe broad temporal patterns of population abundances. Few have been conducted at a microscale over short time periods that better capture the dynamical patterns of key populations. These finer resolution studies may better define the likelihood of local pathogen persistence. This study characterizes the landscape distribution and spatio-temporal dynamics of Oligoryzomys fulvescens (O. fulvescens), an important mammalian reservoir in Central America. Information collected in a longitudinal study of rodent populations in the community of Agua Buena in Tonosí, Panama, between April 2006 and December 2009 was analyzed using non-spatial analyses (box plots) and explicit spatial statistical tests (correlograms, SADIE and LISA). A 90 node grid was built (raster format) to design a base map. The area between the nodes was 0.09 km(2) and the total study area was 6.43 km(2) (2.39 x 2.69 km). The temporal assessment dataset was divided into four periods for each year studied: the dry season, rainy season, and two months-long transitions between seasons (the months of April and December). There were heterogeneous patterns in the population densities and degrees of dispersion of O. fulvescens that varied across seasons and among years. The species typically was locally absent during the late transitional months of the season, and re-established locally in subsequent years. These populations re-occurred in the same area during the first three years but subsequently re-established further south in the final year of the study. Spatial

These versions present different solutions to the “problems” of Flaubert’s style. In fact, translated books content many aesthetic and formal modifications that are intimately related to the strategies actives into the literary system that receives the resultant text. However, there is a kind of double gaze in the translator’s work that hides the simultaneous development of other aspects that are not literary features.

Assuming that photovoltaic power systems were installed at two points, Shinjuku Tokyo and Chino Nagano, a study was conducted of difference in generated output of the systems caused by the difference in environmental factors. In the study, it was assumed that two of the photovoltaic power system with rated capacity of 3kW were installed at the two points, and the annual generated output was calculated and compared by the conventional method considering only cell temperature and the output estimation method considering intensity of solar radiation, cell temperature, and spectral distribution of solar radiation. The result of the study was as follows: the difference in output ratio at the two points was 1.7% or lower under the influence of intensity of solar radiation and cell temperature. On the other hand, under the influence of the distribution of spectral solar radiation, the difference is larger than under other environmental factors, 2.4% in polycrystalline Si and 5.5% in amorphous Si. The generated output estimated by the conventional method and the spectral method produced a difference between 81 kWh in Tokyo and 258 kWh in Nagano in amorphous Si. This is because environmental factors such as intensity of solar radiation and distribution of spectral solar radiation are different between the two points. 1 ref., 2 figs., 3 tabs.

En efecto, en Contemporáneo del mundo (1962 y Las condiciones de la época (1967, aún se advierte cierta fe en el poder de la palabra de incidir en lo social, por lo cual predomina una mirada volcada hacia el mundo externo, atravesado por las coordenadas de la historia. El viraje que se observa a partir de los poemarios de la época de “plomo” se sustenta en un repliegue de la mirada hacia el mundo interno, acompañado de un creciente protagonismo de lo físico, a tal punto, que el cuerpo deviene metáfora de la enfermedad social. A partir de estos cambios, proponemos la hipótesis de que, ante la experiencia de lo intolerable, las estrategias de solapamiento del discurso se constituyen en una forma de preservación del yo y de la poesía.The aim of this work is to study Joaquín Giannuzzi´s books of poems Señales de una causa personal (1977 and Principios de incertidumbre (1980 published during the Argentine military dictatorship.

J.L. Aranguren: reformador moral en época de crisis

Full Text Available Not available.

En el doble tono del pensamiento de Aranguren -el del filósofo moral y el de moralista- es el segundo el que lleva el cantus firmus y constituye el estilo del pensador. En este sentido, la obra de J.L. Aranguren continúa creadoramente la gran tradición moralista del pensamiento hispánico. Remedando la expresión orteguiana, podría definirse como «experimentos morales de nueva España», poniéndola en forma moral. A la vez, pervive en ella el aliento unamuniano de una profunda reforma del ethos del catolicismo español. Pero J.L. Aranguren ha realizado su vocación de reformador moral en un ejercicio de transmutación íntima, de autodesprendimiento irónico y transcendimiento utópico del propio si mismo. En otros términos: ha llevado a cabo su tarea de reformador en la tensión entre el desbloqueo crítico de la experiencia moral y su apertura hacia un nuevo horizonte. En un primer momento, el ámbito de experimentación estuvo demarcado por el «buen talante» católico y una metafísica intelectualista zubiriana, que fraguaron en una ética normativa, abierta a las diferentes esferas de la cultura y de profunda inspiración religiosa. Posteriormente, la exploración de la crisis nihilista de Occidente produjo una profunda inflexión en su planteamiento. La crisis determinó un «repliegue ético» decisivo, es decir, una mayor vecindad al planteamiento kantiano, poniendo ahora el acento en la actitud o existencia ética en sí misma, por encima de los contenidos. En sustitución del estilo fundamentalista de la metafísica, el factum moral y el mundo de la vida son ahora los dos focos de constitución de la experiencia moral. Paralelamente, la tarea del reformador moral se centra en el sondeo de la desmoralización utópica de la existencia. La crítica se ejerce fragmentariamente, a piezas sueltas, en torno a los problemas más acuciantes de la experiencia moral: violencia, consumismo

Methods: Chitosan was selected as the biological membrane carrier to prepare sustained-released membranes. Twelve micrograms of 5-FU or MMC was covalently conjugated onto the membranes by solvent volatilization. Rabbits underwent glaucoma filtration surgery and were randomly allocated into one of the four treatment regimens: glaucoma filtration operation with no implantation of chitosan membrane group (as control, drug-free chitosan membrane implantation group (blank/placebo group, membrane containing 5-FU treatment group (5-FU group, and membrane containing MMC treatment group (MMC group. Each group consisted of 12 rabbits. Intraocular pressure (IOP was measured and evaluated over a 28-day period follow-up preoperatively, then after surgery on days 1, 3, 5, 7, 14, 21, and 28 by Tono-Pen. The aqueous humor was analyzed in each experimental and control groups at days 4, 6, 8, 10, 12, 14, 16, and 20 after operation. Bleb survival and anterior segment were examined with a slit lamp microscope and photographed simultaneously. Two rabbits from each group were killed on day 28 and eight eye samples obtained for histopathological study. Corneas and lenses were examined by transmission and scanning electron microscopy. Results: Both 5-FU and MMC significantly prolonged bleb survival compared with control groups. The filtering bleb’s survival period was significantly more prolonged in the MMC and 5-FU groups (maintained 14 days than the

To compare the short-term effects of timolol 0.5%, brimonidine 0.2%, dorzolamide 2%, and latanoprost 0.005% on intraocular pressure (IOP), blood pressure (BP), and diastolic ocular perfusion pressure (DOPP), calculated as the difference between the diastolic blood pressure (DBP) and IOP. According to a 4 x 4 Latin squares design for repeated measures, 27 untreated patients and patients with newly diagnosed primary open-angle glaucoma (POAG) were treated with timolol 0.5% at 8 AM and 8 PM; brimonidine 0.2% at 8 AM and 8 PM; dorzolamide 2% at 8 AM, 2 PM, and 8 PM; and latanoprost 0.005% at 8 PM. The duration of each treatment course was 6-weeks, with a 4-week washout between each treatment. IOP and BP were measured at baseline and at the end of each treatment period. IOP was measured every 2 hours throughout a 24-hour period. Sitting IOP was measured from 8 AM to 10 PM by Goldmann applanation tonometry. Supine IOP was assessed from 12 to 6 AM by means of a handheld electronic tonometer (TonoPen XL; Mentor, Norwell, MA). BP monitoring was performed by means of an automated portable device (TM-2430; A & D Co., Saitama, Japan). All the drugs tested decreased the IOP significantly at all time points in comparison with baseline pressure. The mean 24-hour IOP after latanoprost administration (16.62+/-0.98 mm Hg) was significantly lower than that after timolol, brimonidine, or dorzolamide (P=0.0001). During the 24-hour period, brimonidine induced a significant decrease in systolic BP (SBP) and DBP at all time points when compared with baseline measurements and with those after administration of the other drugs (P<0.0001). Timolol caused a significant decrease in DBP and SBP at all the 24-hour time points when compared with the baseline and with the dorzolamide- and latanoprost-induced changes (P<0.0001). The mean 24-hour DOPPs were 50.7+/-5.9 mm Hg at baseline, 53+/-5.5 mm Hg with timolol, 46.2+/-5.4 mm Hg with brimonidine, 55.9+/-4.6 mm Hg with dorzolamide, and 56

Full Text Available ResumenEste estudio busca señalar la tipología discursiva propiciada por la Revolución Mexicana y sus políticas culturales, además de la apropiación de los medios de comunicación de los estímulos que la gesta propuso a otros artes. Aquí se describe algunas constantes narrativas de parte de las novelas y los films producidos durante el período revolucionario y el pos revolucionario con la finalidad de relacionarlas, desde una perspectiva estilística, al formato de sociedad que se erigía. Las conclusiones dan cuenta de que la novela y el cine, con estrategias diversas, comparten una visión crítica del mundo revolucionario. En el caso de la literatura, hay una tendencia a retratar, en tono periodístico y naturalista, lo más abyecto de la gesta. En el caso del cine, las manifestaciones más influyentes son las que tangencían a la guerra civil, narrando historias y desplegando figuras que se remontan al periodo de Porfirio Diaz, o idealizando a las consecuencias de la violencia en clave poética y escapista. El resultado de esas operaciones retóricas es la presentación de una especie de imaginación contrarrevolucionaria que, sin embargo, prosperó en el seno de las instituciones creadas a partir del advenimiento de los eventos de 1910, que determinaron una actualización política, económica y cultural en el país a la par con una modernización de los sentidos y de los sentimientos.AbstractThis study seeks to point out some discursive standards stablished by Mexican Revolution cultural policies as well as the media representation. Thus, there is a description of narrative motifs upon which novels and films evoke the war and its contents. The methodological proposal aims to combine stylistic and social signs in order to make up an overview of the main revolutionary representation figures in Mexican art and media discourses in the early 20th century. The conclusion shows that the novel and the movies share a critical point of view

The objective was to compare distribution and intensity of muscular tonus in spastic tetra paretic cerebral palsy (CP), correlating the clinical data with lesion location in the central nervous system. Twelve children aged two to four years old with predominantly cortical lesions (six children) and subcortical lesions (six children) were included. The tonus was analyzed in the upper (UULL) and lower limbs (LLLL) based on Durigon and Piemonte protocol. The result showed that there was no significant difference regarding tonus intensity and distribution in the UULL and LLLL in both groups. Comparing the upper and lower limbs of subjects in the same group, the LLLL presented more asymmetry and higher tonus intensity than the UULL. It was concluded that in this study children with CP as a result of predominantly cortical or subcortical lesions present a similar deficit in tonus modulation, causing a symmetric and homogeneous distribution of hypertonicity, which is predominant in the LLLL.

O diagnóstico é feito pela visualização dos corpúsculos causados por um Arenavírus modificado. Salmonella sp. pertence à microflora de animais de sangue frio e quente, e é um patógeno oportunista que pode causar quadros gastrointestinais ou septicêmicos. Em répteis a Salmonella sp. é a bactéria com maior frequência de citações em espondilites e osteomielites. Relata-se um caso de uma jiboia (Boa constrictor constrictor que apresentava restrição de movimento e múltiplos granulomas dorsais nas vértebras; à radiografia evidenciaram-se regiões fraturadas. Após meses de tratamentos sem melhora clínica e o aparecimento de novas lesões o animal ficou prostrado, anoréxico, caquético e desenvolveu opistótono; optou-se pela eutanásia. À necropsia verificaram-se, nas vértebras, múltiplos focos dorsais com aumento de volume que variava de 1,7cm à 3,8cm. Ao corte as vértebras eram deformadas e exibiam conteúdo caseoso focal próximo ao canal medular, este foi coletado para microbiologia onde se identificou Salmonella sp. À microscopia as vértebras tinham um infiltrado inflamatório multifocal moderado de macrófagos e heterofilos. Algumas áreas possuíam grande quantidade de granulomas com calcificação central e inúmeras células gigantes; outros mostravam áreas de osteomalácia e fibrose.

Nelas se inserem formações florestais higrófilas denominadas Ipucas, como enclaves peculiares pela sua fitossociologia e ambiente pedogeomorfológico. Esses fragmentos florestais naturais ocorrem na planície fluvial, em região de ecótono entre o Cerrado e a Floresta Amazônica. Neste estudo, foi selecionada uma área de 8.200 ha, situada no Município de Lagoa da Confusão, TO, sendo caracterizados nove perfis de solos em diferentes pedoambientes e suas inter-relações nas paisagens da planície do Araguaia, com ênfase nas áreas de Ipucas.

Excetuando as áreas de calcário aflorante na borda elevada da planície, onde predominam Cambissolos Háplicos eutróficos com acentuada riqueza química, os solos predominantes no interior da planície do Médio Araguaia, dominantemente Plintossolos e Gleissolos, são acentuadamente pobres em nutrientes e ácidos, mesmo sob formações florestais de Ipucas. Nessas últimas, há um acúmulo de matéria orgânica pelo ambiente hidromórfico redutor e ácido. Por serem áreas extremamente frágeis a intervenções antrópicas, e pouco interligadas, as Ipucas devem ser consideradas áreas de preservação permanente, sendo estreitamente ligadas ao ciclo hidrológico da planície do Araguaia.Amongst the landscape features of Mid Araguaia river valley, there are vast coalesced floodplains and waterlogging depressions, all seasonally inundated.

Non-Pythagorean proportions and the Diapasón in the design of iberian Harpsichord scales

Directory of Open Access Journals (Sweden)

Poletti, Paul

2009-12-01

Full Text Available One of the tenets of modern organology is that the strings of keyboard instruments have generally been designed according to the theory that length is inversely proportional to pitch, resulting in a progression of string lengths known as a Pythagorean Scale. Recent research has begun to focus on surviving Iberian instruments, heretofore largely neglected. While few have survived, it would appear that a signifi cant number of their builders had a tendency to employ non-Pythagorean scales. One recent study suggests that these instruments represent a curious collective adherence to archaic methods used in the design of Medieval instruments. The present article offers an alternative viewpoint, showing how such scales could easily have been constructed using a traditional organ builder’s design tool, called a Diapasón. The geometric logic of the Diapasón is briefl y explained as well as the various progressions which can result from its use. The scales of several Iberian instruments are then examined in light of these alternative methods, arriving at the conclusion that their makers, rather than exhibiting an archaic conservatism, actually formed part of growing 18^th century movement towards the use of extended non-Pythagorean scales as are now ubiquitously found in the modern piano.

Uno de los principios de la organología moderna es que las cuerdas de los instrumentos de teclado se han diseñado generalmente según la teoría que la longitud es inversamente proporcional al tono, dando por resultado una progresión de las longitudes de la secuencia conocidas como escala pitagórica. La investigación reciente ha comenzado a centrarse en los instrumentos ibéricos supervivientes, descuidados hasta ahora en gran parte. Mientras que pocos han sobrevivido, se ha constatado que un número signifi cativo de sus constructores tenía una tendencia a emplear escalas no-Pitagóricas. Un estudio reciente sugiere que

Full Text Available En la última década se ha aportado clara evidencia de que tanto nucleósidos como nucleótidos de adenina y uridina pueden funcionar como factores de señalización extracelular. Su acción es mediada por dos tipos principales de receptores de superficie denominados purinérgicos. Los receptores P1 se activan por adenosina, y son todos metabotrópicos, mientras que los receptores de nucleótidos (ATP, ADP, UTP y UDP y nucleótidos-azúcares (UDP-glucosa y UDP-galactosa pueden ser metabotrópicos (P2Y o ionotrópicos (P2X. La importancia y complejidad de este sistema de señalización se evidencia por la diversidad de mecanismos de liberación de nucleótidos al medio extracelular y por la distribución ubicua de varios grupos de ectonucleotidasas capaces de catalizar la degradación y conversión de nucleótidos. Hasta el momento se han descrito y clonado una veintena de estos receptores que modulan una variedad de respuestas, como el impulso nervioso, la respuesta inflamatoria, la secreción de insulina, la regulación del tono vascular y la percepción del dolor. En la presente revisión se describen las características estructurales y farmacológicas de los receptores purinérgicos y se analiza la interacción dinámica entre estos receptores, los nucleósidos y nucleótidos, y las ectonucleotidasas, con especial atención a la dinámica de la agregación plaquetaria, la respuesta inmune y la hidratación de las mucosas respiratorias.In the last decade evidence accumulated that nucleosides and nucleotides of both uridine and adenine can act as extracellular signaling factors.

Por sua proximidade com a caatinga e o cerrado, o LSN permite a co-existência de espécies destes Domínios conjuntamente com espécies de restinga, em diferentes formações, constituindo um Complexo Vegetacional. Apesar da grande importância ecológica e botânica deste ecótono, existem poucos estudos sobre a flora regional. O objetivo deste trabalho foi aprofundar o conhecimento sobre a composição florística e fitossociológica da região. Para isso, fizemos um levantamento florístico na área (entre 2007-2011, bem como consultas a registros de herbário na região e um levantamento fitossociológico em um trecho da floresta estacional semidecídua costeira (mata de tabuleiro. Foram inventariadas 382 espécies vegetais, pertencentes a 96 famílias. Na parcela fitossociológica (0,32 ha foram registrados 2.970 indivíduos de 52 espécies, sendo as mais abundantes as arbóreas Manilkara triflora, Chamaecrista ensiformis e Guapira nitida e as arbustivas Cordiera sessilis e Maytenus erythroxyla (altura média 3,8 m, diâmetro médio 6,2 cm, área basal 39,28 m²/ha.

Full Text Available Non-verbal communication is predominant in the mother-child relation. This study aimed to analyze non-verbal mother-child communication in conditions of maternal HIV. In an experimental environment, five HIV-positive mothers were evaluated during care delivery to their babies of up to six months old. Recordings of the care were analyzed by experts, observing aspects of non-verbal communication, such as: paralanguage, kinesics, distance, visual contact, tone of voice, maternal and infant tactile behavior. In total, 344 scenes were obtained. After statistical analysis, these permitted inferring that mothers use non-verbal communication to demonstrate their close attachment to their children and to perceive possible abnormalities. It is suggested that the mother’s infection can be a determining factor for the formation of mothers’ strong attachment to their children after birth.La comunicación no verbal es predominante en la relación entre madre/hijo. Se tuvo por objetivo verificar la comunicación no verbal madre/hijo en la existencia del HIV materno. En ambiente experimental, fueron evaluadas cinco madres HIV+, que cuidaban de sus hijos de hasta seis meses de vida. Las filmaciones de los cuidados fueron analizadas por peritos, siendo observados los aspectos de la comunicación no verbal, como: paralenguaje, cinestésica, proximidad, contacto visual, tono de voz y comportamiento táctil materno e infantil. Se obtuvo 344 escenas que, después de un análisis estadístico, posibilitó inferir que la comunicación no verbal es utilizada por la madre para demonstrar su apego íntimo a los hijos y para percibir posibles anormalidades. Se sugiere que la infección materna puede ser un factor determinante para la formación del fuerte apego de la madre por su bebé después el nacimiento.A comunicação não-verbal é predominante na relação entre mãe/filho.

ágicos hechos de Cajamarca. Pero más allá de determinar si algunas de las tonadas del Códice pudieran ser parte de una representación de la captura y muerte de Atahualpa de finales de la colonia, nos interesó interpretar estos cantos como signos portadores de un discurso colonial propio en dos sentidos: la relectura de hechos históricos cuales la captura y la muerte de Atahualpa; la persistencia de códigos andinos en la rememoración de ciertos rituales como el "llanto ceremonial". En este sentido se consideró, para el análisis musical, la existencia de un tono -visto en un primer momento como elemento perteneciente a un sistema de tonos incaicos cercano al sistema de modos eclesiásticos-, que llamaremos "llanto del Inca", su relación con el llanto ceremonial incaico y su rol en la transmisión de significados ligados a la ritualidad andina colonial.Throughout the colonial period a memory of the history of the Andean tribes was created. This memory considered the Inca empire as its main reference and the Inca as its natural symbol. From the narration of the facts of the Inca history, particularly those referring to the Spanish conquest, sprang up the myth of the Inca death to which contributed both conquerors and those who were conquered. During the eighthteenth century the death of the Inca was presented in numerous theatrical performances accompanied with music. The codex Martínez Compañón (1782-85 consists of nine volumes with about 1500 color plates depicting different aspects of both the social life and the natural phenomena of the Trujillo zone in Peru. Thirty eight plates, included in volume II, are related directly or indirectly with music of oral tradition of the period. The original folio numbers of these plates are all preceded by the letter E, standing for '"estampa" (plate. A total of twenty scores appear between E. 176 though E. 193. Judging from the title the text of the following two tunes -"E 188: Allegro tonada El tupamaro, Caxamarca" and "E. 191

Full Text Available Durante las últimas cuatro décadas del siglo pasado el crecimiento demográfico de México ha ido disminuyendo ostensiblemente. Esta tendencia ha continuado incluso durante la primera década del siglo XXI, a tono con las expectativas vigentes sobre el tema en el país. Sin embargo, y precisamente durante las mismas décadas, en los territorios costeros del país se viene presentando un fenómeno inverso, es decir: un crecimiento demográfico resultante de la migración hacia ellas, no del crecimiento promedio de las tasas de natalidad que, por cierto, se mantienen más o menos semejantes a las que imperan entre el resto de habitantes de la nación. Este fenómeno por sí mismo es prueba fehaciente del crecimiento de la inversión de capital tanto pública como privada en los territorios costeros. La única excepción a esta tendencia es la de tres municipios costeros sinaloenses creados a principios de la década de 1990 y tomados literalmente por las actividades del narcotráfico. Los nuevos habitantes de las costas mexicanas suelen ser en su inmensa mayoría personas llegadas de tierra adentro en busca de trabajo que les permita alcanzar mejores condiciones de vida. Para estos “costeños” de nuevo cuño la vida en esas latitudes es completamente distinta a la que llevaban en sus lugares de habitación anterior hayan sido éstos el altiplano o la mesa central, los desiertos norteños, los calcáreos terrenos del interior de la península de Yucatán o las intrincadas laderas de nuestras montañas: nuevos el ritmo y la manera de trabajar, distintas las costumbres alimenticias y de vestimenta locales, desconocidos los fenómenos climáticos y sus consecuencias en la vida cotidiana, extraños los modismos idiomáticos, exótico –en fin- el aprecio de los nativos costeños por su paisaje y su flora y fauna locales. Para analizar el caso de estudio se propone el concepto de “región costera”, haciéndose uso de información demogr

Polonia actual?En la Polonia actual la evolución de los modelos de compromiso cívico y político es particularmente visible en las jovenes generaciones. Entre los nuevos experimentos de participación política, las nuevas tecnologías de la información y de la comunicación permiten reconfigurar radicalmente el espacio público. La juventud polaca se vuelca masivamente en la Web. En el contexto de la expresión libre que permite el ciberespacio nos focalizamos en el desarrollo de un discurso que adopta el tono de la irrisión y de la sátira política. Han surgido una multitud de páginas web críticas, de caracteristicas aparentemente contestatarias, y de oposición basados en la sátira, con la voluntad común de aportar una respuesta a la situación política.

este artículo una viva polémica por sus acaloradas alabanzas de Clarín como crítico, novelista y cuentista y también por su tono burlesco y despectivo, al estilo del propio Clarín, uno de los autores peninsulares más leído y discutido en Hispanoamérica en su momento. Los críticos han comentado las relaciones literarias entre Clarín y Gómez Carrillo a partir de 1892, tras la llegada del guatemalteco a Madrid y tras la reseña clariniana del primer libro de su colega de ultramar. Este artículo, publicado dos años antes, es una demostración de la sincera devoción que Gómez Carrillo sentía por Clarín cuando todavía no le debía nada.

Full Text Available O presente trabalho busca descobrir a face pedagógica de Eros. Como ponto de partida, está o fato de a figura do educador/professor ser comumente representado por alguém cuja ocupação não suscita desejos de qualquer espécie. Não raras vezes assistimos a representações literárias e imagens televisivas ou cinematográficas nas quais o professor aparece comicamente como uma caricatura que fala, de modo monótono e sem parar, a alunos cujos rostos oscilam entre o tédio e o escárnio. No entanto, o que é de fato assustador é que, cada vez mais, as imagens que aparecem no discurso das novas gerações, numa tentativa de oposição à caricatura supracitada, associam a figura do professor à de um animador de auditório, performático, divertido, especialista em dinâmicas grupais catárticas, sem conteúdo e igualmente caricatural. Procurando, então, desviar-se de ambas as caricaturas e refletir sobre o gênero específico de libido pedagógica - compreendido como força ou energia espiritual para o progresso moral, intelectual e sensível -, o texto recupera o poder ilustrativo do mito, pensa sobre a força do imaginário na constituição de parâmetros modelares para a Educação e para o exercício da mestria (para isso, propõe notas socráticas, sofísticas e escolásticas com ênfase na linguagem e aponta para a importância dessa discussão diante dos problemas que habitam os espaços educativos contemporâneos.The present work seeks to uncover the pedagogical face of Eros.

os mecanismos periféricos responsáveis pela redistribuição de fluxo sanguíneo produzidas pela EE do hipotálamo. Os resultados obtidos demonstraram que 1 em ratos anestesiados a EE do hipotálamo produziu hipertensão arterial, taquicardia, vasoconstrição no leito mesentérico e acentuada vasodilatação dos membros posteriores; 2 a combinação do bloqueio farmacológico de receptores alfa1 e alfa2 adrenérgicos com fentolamina mais adrenalectomia bilateral reduziu a vasoconstrição mesentérica e a vasodilatação dos membros posteriores. Nestes animais o bloqueio da síntese de NO com L-NAME provocou nova redução significante da vasodilatação dos membros posteriores; 3 a administração de L-NAME, previamente o bloqueio farmacológico com fentolamina mais adrenalectomia bilateral, reduziu as respostas de vasoconstrição mesentérica e de vasodilatação dos membros posteriores. Estes resultados sugerem a existência de pelo menos três possíveis mecanismos responsáveis pela vasodilatação dos membros posteriores induzida pela EE do hipotálamo: 1 ativação de receptores beta-adrenérgicos por catecolaminas liberadas pela medula adrenal; 2 redução do tono vasoconstritor simpático e 3 um terceiro mecanismo que utiliza NO como mediador.

Full Text Available No município de Colniza, Mato Grosso, a principal limitação para expansão pecuária é a ocorrência de "morte súbita" em bovinos, com registros de mortalidade próxima a 50% dos animais. Em visitas realizadas em áreas de ocorrência do problema, nos anos de 2004, 2011 e 2012, constatou-se que havia coincidência entre a ocorrência de "mortes súbitas" no rebanho e a presença de Amorimia pubiflora nas pastagens. As mortes ocorrem durante todo ano, porém acentuam-se no início do período das chuvas, quando há maior quantidade de brotação nas áreas de pastoreio. A intoxicação foi reproduzida em ovinos e bovinos através da administração de folhas jovens coletadas em dois períodos do ano, e, em ovinos, através de folhas maduras e dos frutos. Nos ovinos que morreram, as primeiras manifestações clínicas foram observadas entre 34min e 17h34min após a administração da planta e a evolução clínica foi de 3min a 15h20min, com uma fase final superaguda de 3 a 21min. As principais alterações clínicas encontradas foram taquicardia, evidenciação da jugular, tremores musculares, apatia e relutância à movimentação. Todos os sinais acentuavam-se após a movimentação. A fase final superaguda foi caracterizada por relutância para caminhar, cifose, tremores e contrações musculares generalizadas, principalmente de membros, cabeça e pescoço. Notou-se também taquipneia com respiração abdominal, decúbito esternal e rapidamente lateral ou quedas em decúbito lateral, opistótono, nistagmo e cianose de mucosa oral, seguidos de morte. As folhas jovens, independentemente do período da coleta, foram mais tóxicas; causaram a morte de ovinos a partir de 2g/kg e de um bovino que ingeriu 3g/kg.

The model project aims at integration of Eastern Integrated Power System in the Far East and Russian Unified Power System, and development of abundant undeveloped hydraulic and tidal power generation in the Far East. The study result showed that (1) construction of the high-voltage DC power transmission (HVDC) system of model project class voltage and capacity in Eastern Siberia is possible technically enough, (2) the total construction cost of the model project scheduled to be put into operation in 2025 amounts to nearly $4.7 billion, and (3) the model project is environment-friendly without any CO{sub 2} gas emission because of hydraulic and tidal power generation.

las técnicas suponen un aumento de problemas de impresión de importancia en el producto. Un aumento en la resolución de impresión supone la aparición de nuevos problemas en la estabilidad del tono producido por la mayor dificultad de control de punto de impresión. Este problema es especialmente grave en la cerámica donde se exige una homogeneidad tonal de todo el producto fabricado. En el presente artículo se describen las interacciones que existen entre las variables de diseño, los sistemas de impresión y las características físico-químicas de las tintas que afectan a la estabilidad de los diseños en pavimentos y revestimientos cerámicos. El objetivo es destacar la necesidad de controlar sistemáticamente los máximos factores posibles con el fin de reducir la variabilidad tonal productiva. El presente trabajo es parte de un proyecto de investigación centrado en la minimización de la variabilidad tonal en el sector cerámico financiado con fondos Feder-Cicyt.

Full Text Available Se realizó un estudio analítico prospectivo longitudinal a través del seguimiento del neurodesarrollo durante los 2 primeros años de edad corregida en 86 recién nacidos de muy bajo peso al nacer, egresados del Hospital Ginecoobstétrico "Ramón González Coro" de Ciudad de La Habana, entre diciembre de 1988 y agosto de 1993, con el objetivo de evaluar el neurodesarrollo en recién nacidos de muy bajo peso ventilados. Se conformaron 2 grupos de estudio: a Ventilados (26 pacientes y b No ventilados (60 pacientes, entre los que no existían diferencias con respecto a sexo, peso, edad gestacional, pero sí en cuanto al puntaje de Apgar y correspondieron los valores más bajos de éste a los ventilados. No hubo diferencias entre ambos grupos de estudio con respecto a la evolución del neurodesarrollo, pero se detectó una mayor proporción de secuelas neurológicas severas en el grupo de ventilados con relación a los no ventilados (19,2 vs 1,7 %. Las alteraciones del neurodesarrollo más frecuentemente encontradas en los ventilados fueron dentro de las ligeras: la hiperactividad, las alteraciones reflejas, los trastornos transitorios del tono muscular y el retraso ligero del lenguaje. De las alteraciones severas la parálisis cerebral espástica fue la secuela más frecuentemente observada (11,5 %. Se concluye que la ventilación mecánica en sí no parece asociarse con un mayor índice de secuelas del neurodesarrollo en recién nacidos de muy bajo peso, aunque parece actuar como un factor agravante de las lesiones ya establecidas en los casos con depresión severa al nacer.An analytical, prospective and longitudinal study was conducted by following up the neurodevelopment during the first 2 years of corrected age of 86 newborn infants with very low birth weight that were discharged from "Ramon Gonzalez Coro" Gynecoobstetric Hospital between December, l988, and August, 1993.

Full Text Available Este artigo trata de alguns trabalhos poéticos de Ivan Goll, publicados em alemão, francês e inglês, nos quais o diapasão cosmopolita e o apelo a uma poesia supranacional representaram um grito marginal de resistência frente às tendências totalizantes e às categorias nacionais da primeira metade do século XX. Busca-se compreender se o grito encontra respaldo nas reflexões atuais, pensando-o como um antecedente questionador de taxonomias de gênero literário e de forma artística, um transgender. Assinala que o modernista brasileiro Mário de Andrade não somente acompanhou a querela entre Goll e Breton sobre a herança do conceito Surréalisme legado por Apollinaire, como também se correspondeu e trocou livros com o poeta alsaciano, tendo recebido com entusiasmo a antologia Les Cinq continents. Ao final, este artigo apresenta a tradução de dois poemas afinados com a noção cosmopolita: "O Negro do Teatro de Variedades" e "A Canção de João Sem-Terra, O Duplo".Esta comunicación trata sobre algunos trabajos poéticos de Ivan Goll, publicados en alemán, francés e inglés, en los cuales el tono cosmopolita y el llamamiento a una poesía supranacional representaron un grito marginal de resistencia frente a las tendencias totalizantes y a las categorías nacionales de la primera mitad del siglo XX.

Full Text Available La hiperplasia prostática benigna, enfermedad común en hombres a partir de los 50 años de edad, consiste en el crecimiento benigno e incontrolado de la glándula prostática y produce diversos síntomas del tracto bajo urinario. Su agente causal multifactorial involucra fundamentalmente el incremento de la conversión de testosterona en dihidrotestosterona por acción de la 5 a-reductasa prostática, lo cual desencadena eventos que propician el incremento en el tamaño de la próstata (componente estático y el aumento del tono del músculo liso de vejiga y próstata (componente dinámico regulado por los adrenoreceptores (ADR-a1. El tratamiento farmacológico de la hiperplasia prostática benigna incluye los inhibidores de la 5a-reductasa, antagonistas de ADR-a1, su terapia combinada y la fitoterapia. El objetivo del presente trabajo fue presentar los aspectos más relevantes de la farmacología de los fármacos utilizados en el tratamiento de la hiperplasia prostática benigna y brindar elementos de su eficacia, seguridad y tolerabilidad. Para ello, se realizó una reseña de los diferentes fármacos utilizados en el tratamiento de esta afección, los que fueron clasificados de acuerdo con su mecanismo de acción. Se incluyeron productos de origen natural como los extractos lipídicos del Serenoa repens y Pygeum africanum, así como el D-004, extracto lipídico de los frutos de la Roystonea regia, que ejerce efectos beneficiosos sobre los principales factores causales de la hiperplasia prostática benigna, ya que es un inhibidor de la 5 a-reductasa prostática, un antagonista de los ADR-a1, un inhibidor de la 5-lipooxigenasa y tiene acción antioxidante, lo que evidencia un mecanismo multifactorial. Los resultados hasta el presente indican que el D-004 es seguro y bien tolerado.Benign prostatic hyperplasia is a common disease in over 50 years-old men consisting in uncontrolled and benign growth of prostatic gland that leads to lower urinary

As variáveis cardiorrespiratórias foram mensuradas antes da indução (basal, imediatamente após a indução, e então a cada 15 minutos, durante 90 minutos. Amostras de sangue arterial também foram colhidas para análise de gases sanguíneos, exceto aos 45 e 75 minutos após a indução. A pressão arterial média diminuiu significativamente com a utilização de ambos os tratamentos, enquanto o índice cardíaco reduziu significativamente somente com o tratamento MICRO. O tempo necessário para extubação, decúbito esternal, deambulação e recuperação total foi semelhante em ambos os grupos. Opistótono foi observado em 33% dos animais em cada tratamento. A microemulsão de propofol apresentou parâmetros clínicos e respiratórios semelhantes àqueles obtidos com a emulsão lipídica comercialmente disponível, porém mostrou algumas características hemodinâmicas diferentes, quando utilizada para a indução e manutenção da anestesia. Com base somente nesses resultados, não são observadas vantagens na utilização da microemulsão.

La Formación Bajo de la Carpa se compone de areniscas, finos bancos conglomerádicos alternados con pelitas y capas de vaques. La Formación Anacleto está compuesta de capas arenopelíticas. La Formación Rentería está mayormente compuesta por conglomerados con clastos que alcanzan 15 cm de longitud, incluídos en una matriz sabulítica. El análisis de facies sugiere un regimen fluvial, con un control subacuático que oscila entre energía media y alta. Los canales arenosos, lenticulares, poseen estratificación entrecruzada indicando un agente de transporte unidireccional. El análisis tafonómico indicaría que el dinosaurio murió en las cercanías de los márgenes del río, siendo rápidamente incorporado a los sedimentos fluviales y sepultado en sucesivos eventos. La distribución especial de los huesos revela un corto transporte desde la fuente de aporte, con una leve orientación hacia el norte. La presencia de dos series de vertebras caudales con arqueamiento opistótono indican que el animal fue expuesto un período suficiente de tiempo para que actúe el rigor mortis y la disecasión.

El estudio de la VFC comenzó hace 30 años, aproximadamente, y ha ganado mayor importancia en los últimos 10 años. Existen varios métodos para evaluar la VFC. Los más aceptados actualmente son los métodos en el dominio de la frecuencia (análisis espectral. El análisis espectral consiste en descomponer el tacograma, el cual se asemeja a una onda compleja, de manera que se obtienen los componentes espectrales, y se encuentran componentes de alta frecuencia (HF, relacionados con el tono parasimpático, uno de baja frecuencia (LF, relacionado con la modulación tanto simpática como parasimpática y otro de muy baja frecuencia (VLF, el cual no se ha relacionado con el SNA. Los métodos del dominio del tiempo, son básicamente estadísticos y evalúan la variabilidad por medio de promedios y desviaciones estándar. Son los más conocidos, pero al parecer tienen menos ventajas que los métodos espectrales. La VFC se correlaciona con adaptaciones fisiológicas a cambios en el medio interno, externo y a la presencia de enfermedades. En este artículo se explican los principales métodos en el dominio de la frecuencia y del tiempo y la relación que tiene la VFC con las adaptaciones fisiológicas y con enfermedades específicas.

Sin embargo, a pesar de su relevancia como espacios para el tratamiento de estos problemas, las áreas metropolitanas tienen grandes dificultades para transformarse en territorios políticos, es decir, para alcanzar un nivel de agente político suficiente (como actor colectivo para producir políticas adecuadas que aborden estos problemas y produzcan estrategias colectivas que orienten su desarrollo futuro. Para tratar este tema, este artículo se centrará en primer lugar en los principales obstáculos que les impiden alcanzar el nivel de actor político, que son comunes a la mayoría de los países europeos: la resistencia del Estado a otorgar a estos territorios las funciones y recursos adecuados en el proceso de descentralización y su preferencia por el reforzamiento de los niveles de gobierno existentes; la oposición de estos niveles de gobierno y la falta de apoyo de la sociedad civil (actores económicos y población. En un segundo apartado, este artículo presentará diferentes experiencias que han tenido lugar en la última década para superar estos obstáculos. Centrándose en la pacificación de las relaciones de poder a nivel metropolitano mediante conferencias, cartas y pactos metropolitanos y “políticas procedimentales” como la planificación estratégica, el autor considera que estas experiencias no parecen ofrecer potencialidades para la reducción del conflicto político entre actores y concluye con un tono pesimista sobre la gobernabilidad de las áreas metropolitanas.Metropolitan areas have become places where some of the major issues and stakes for the government of our societies are taking place (social and territorial

author characterizes community arts, reflects on collective artistic creation as a tool of subjectivization, and discusses some of the political stakes raised by these original artistico-social practices.Cada vez más artistas norteamericanos optan por un compromiso con ciertas comunidades o colectividades estigmatizadas y marginadas, con el fin de crear obras colectivas en estrecha colaboración con sus miembros. Tales prácticas artísticas, son llamadas « artes comunitarias » y persiguen un doble objetivo. Por un lado, el de explorar –por medio de la creación– el sufrimiento individual y colectivo generado por las relaciones sociales de dominación (para dar pie a un proceso de subjetivación que puede hacerse político ; y por otro lado, para rechazar tales relaciones de dominación por medio de obras artísticas de tono crítico. Este tipo de resistencia contraviene el principio moderno de espacio público y de acción política, no sólo porque rechaza la estricta separación entre lo privado y lo público, sino también porque propone experiencias singulares y formas diferentes de deliberación política. Es por ello que, en este artículo, la autora precisa lo que son las artes comunitarias, reflexiona sobre la creación artística colectiva como instrumento de subjetivación y discute sobre algunos retos políticos que plantean estas prácticas artístico-sociales originales.

El Trastorno Afectivo Bipolar (TAB se caracteriza por episodios fluctuantes y cíclicos de oscilación del estado de ánimo o tono energético vital, de días, semanas o meses de duración, que pueden ir desde el apagamiento vital global o depresión hasta la exaltación vital global o manía. Estos ciclos están separados usualmente por períodos de remisión completa de la sintomatología. Su curso es generalmente crónico y recurrente (Kaplan y Sadock 1995, DSM IV.

La prevalencia del TAB en la población general varía del 0.4 al 1.6%. En el Segundo Estudio de Salud Mental realizado en Colombia en el año de 1997 se encontró que la prevalencia en la vida de TAB I es de 1.2%, siendo un poco más alta en hombres (1.3% que en mujeres (1.1% (Torres y Montoya 1997.

Desde hace varias décadas, numerosos estudios del TAB incluyendo estudios de agregación familiar y de gemelos han indicado la existencia de un componente genético importante en la etiología de esta enfermedad (Craddock y Owen 1996, Craddock 1996, DePaulo y McMahoon 1996, Freimer 1997, Plomin et al. 1997.

Hasta ahora han sido varios los genes candidatos en la susceptibilidad a desarrollar TAB, sin embargo, la identificación de genes que juegan un papel importante en la etiología del TAB es muy probablemente el reflejo de la complejidad clínica y genética de esta entidad, la cual no sigue un patrón de herencia mendeliano simple (Reus y Freimer 1997. Hasta el momento se han publicado estudios que reportan ligamiento genético a múltiples regiones del genoma, sin embargo, los diversos reportes positivos de ligamiento son difíciles de comparar debido, entre otros, a la variabilidad de

Este trabalho objetivou avaliar a composição florística e obter parâmetros fitossociológicos de componentes arbóreos presentes em um fragmento urbano no município de Sinop, Mato Grosso com vistas a confirmar sua classificação como vegetação de transição e detectar indícios de perturbação pela fragmentação. A vegetação foi amostrada pela instalação de 25 parcelas permanentes de 20 x 20m, onde foram amostrados os indivíduos com CAP igual ou superior a 15 cm à altura de 1,30m do solo. A densidade total da área foi de 1555 ind./ha, distribuídos em 37 famílias botânicas, 81 gêneros e 113 espécies. A família mais representativa foi Leguminosae com 14 espécies. As espécies que mais contribuíram em abundância e apresentaram maior frequência foram: Cecropia sciadophylla, Cecropia sp., Bellucia grossularioides e Vismia guianensis. O índice de Shannon (H' foi de 3,55, considerado alto para uma floresta de transição. A equabilidade de Pielou foi de 0,75, sugerindo grande dominância de poucas espécies. As espécies que mais se destacaram em ordem decrescente de VI (% foram Cecropia sp., Bellucia grossularioides, Qualea ingens, Cecropia sciadophylla, Vismia guianensis, Miconia prasina, Trattinickia burserifolia, Unonopsis guatterioides e Schefflera vinosa.

Histologicamente havia meningoencefalite. O controle da doença na propriedade com tratamento específico dos casos clínicos com aceturato de diminazene foi eficiente, pois após o tratamento não se verificou mais a presença do parasita em esfregaços sanguíneos nem evidência clínica da enfermidade em até 2 meses após o início do surto. Os fatores epidemiológicos favoráveis à ocorrência dos surtos foram a abundância de vetores mecânicos, como tabanídeos e Stomozys spp., e a entrada, no rebanho, de animais oriundos de propriedades onde ocorreu a doença em questão. Sugere-se que o semi-árido do Nordeste, devido a períodos prolongados de secas e altas temperaturas, é região de instabilidade enzoótica para a tripanossomíase, em conseqüência, provavelmente, ao ambiente desfavorável para o desenvolvimento de vetores durante a maior parte do ano.Two outbreaks of trypanosomiasis by Trypanosoma vivax, reported in cattle, occurred on two farms

Full Text Available En los últimos años es mayor el interés por el manejo del síncope de diferentes causas debido a su frecuencia, naturaleza incapacitante, su gravedad potencial y a los problemas complejos implicados en su génesis y difíciles de diagnosticar. El síncope se ha definido como la pérdida súbita, breve y transitoria del estado de conciencia, con incapacidad para mantenerse en pie, ausencia del tono postural y recuperación espontánea. El síncope vasovagal es el más común y produce una de las respuestas de vasodilatación más poderosa en los humanos. En su producción se halla implícita una disfunción breve de reflejos cardiovasculares vasodepresores con sisminución del metabolismo cerebral, como consecuencia de la deprivación de sustancias energéticas esenciales. La pérdida de conciencia puede ser causada por muchos trastornos, en su mayoría de origen benigno, tal como la reacción vasopresora, que es la más frecuente y no recurrente; sin embargo en una proporción pequeña de casos, el síncope puede ser causado por un trastorno peligroso para la vida como la taquiarritmia ventricular y ser causa de muerte súbita. Su mecanismo de producción más frecuente es el reflejo bradicárdico. El estudio del síncope es un problema complejo que requiere de una guía clínica que lo racionalice. No hay evidencia de la utilidad diagnóstica de las pruebas de neuroimagen, EEG o estudios vasculares en los pacientes con este trastorno cuando no hay signos de focalidad neurológica. La prueba de mayor rentabilidad diagnóstica en el estudio del síncope de causa no aclarada es la mesa basculante. Se deben remitir estos casos al neurólogo solo cuando existan signos neurológicos de disfunción focal, si hay dudas de que se trate de crisis epilépticas o cuando la valoración por el cardiólogo, incluyendo el estudio con la mesa basculares, es negativa.In the last few years, the interest for the syncope of different causes has grown due to its

A hydrochemical investigation using 36Cl/Cl in groundwaters

International Nuclear Information System (INIS)

Metcalfe, Richard

2003-03-01

This report describes 36 Cl studies which were undertaken during the H14 financial year. The results of this study suggest that, if 36 Cl data can be obtained for groundwaters at spatial scales comparable with, or smaller than, the spatial scales of the variability in in-situ 36 Cl production in the host rock, the data could potentially be useful for interpreting groundwater origins and flow paths. Four groundwater samples and one onsen water sample from the Tono area were collected for 36 Cl analysis. The groundwater samples came from boreholes MSB-2 and MSB-4 in the MIU Construction Site, whereas the onsen water was taken from Oniiwa Onsen (Komatsuya). In addition, a single sample from borehole HDB-1 at Horonobe was also sent for analysis. Supporting rock chemical data and wireline geophysical data have also been evaluated, to provide a basis for interpreting the 36 Cl data. Rock analyses and spectral gamma wireline data were used to estimate theoretical limiting equilibrium 36 Cl/Cl ratios in the rock. These have been compared with the compositions measured for groundwater samples, enabling a judgement to be made as to: whether the waters have resided for long enough in the rock to approach equilibrium (> c. 1.5 Ma); the spatial scales of mixing of the dissolved Cl in the groundwater. The estimates of in-situ 36 Cl/Cl production made with the newly available rock chemical data and wireline geophysical data have enabled 36 Cl data obtained previously from MIU-4, KNA-6 and DH-12 during H12 and H13 to be interpreted more confidently. In particular it seems that 36 Cl/Cl ratios measured previously in groundwater samples from MIU-4 are not in equilibrium with in-situ production in the granite. Furthermore, they imply that the Cl is homogenised, at least on the scale of the upper half of borehole. In contrast, the data from DH-12 imply that the Cl could be in equilibrium with in-situ 36 Cl production in the granite, which would be consistent with a relatively long

La parálisis facial es para el paciente un problema grave, no solo de orden estético y funcional, sino emocional y que puede dejar una deformación facial permanente con pérdida del tono muscular.

Los casos severos llegan a interferir en la expresión del lenguaje, la masticación y funciones elementales de la vida como comer, beber, silvar, afeitarse, etc. Es el nervio de la expresión facial voluntaria e involuntaria y en el hombre existe una grave variedad de movimientos faciales expresivos que exteriorizan diversos estados anímicos que nos
diferencian de los animales y que dan a cada individuo un carácter peculiar. La expresión facial es una función primordial en la vida, y su pérdida produce en el individuo un gran impacto sobre su personalidad, que lo puede llevar a la neurosis o al suicidio. El cirujano debe aceptar la parálisis como una complicación quirúrgica grave y estar preparado

El síncope es una entidad clínica caracterizada por una alteración o pérdida abrupta y transitoria de la conciencia y del tono postural, con recuperación espontánea y completa. El síncope es frecuente en niños y adolescentes. La causa más frecuente es el neurocardiogénico (vasovagal que presenta una evolución benigna. Otras causas son las enfermedades cardíacas, neurológica, metabólica, psicológica o psiquiátrica e intoxicaciones con pronósticos variables, pudiendo llegar a ser severas y ocasionalmente fatales. La evaluación del síncope se basa principalmente en una buena historia clínica y un examen clínico detallado. Pruebas complementarias básicas pueden ayudar en el diagnóstico, como estudios metabólicos, hemogramas y electrocardiograma. La prueba de Inclinación es la prueba por excelencia para confirmar el diagnóstico del Síncope Neurocardiogénico. El tratamiento está indicado en síncopes con episodios recurrentes o con el riesgo de lesiones. La prevención y las medidas educacionales están indicadas en todos los pacientes con síncope. Un tratamiento específico debe ser indicado para cada paciente individualmente. En el Síncope Neurocardiogénico con recurrencia frecuente, donde fallan las medidas preventivas o hay riesgo de lesiones con las caídas, son utilizados fármacos como los beta bloqueantes, estimulantes alfa adrenérgicos, inhibidores de la captación de serotonina, fludrocortisona y marcapaso para los casos severos que no responden a los tratamientos farmacológicos. Conclusiones. El Síncope es una entidad clínica frecuente en la infancia y adolescencia con evolución benigna, pero potencialmente letal en los casos de origen cardíaco. Es importante el diagnóstico, y la etiología para elegir el tratamiento específico y

ía del aceite producido en esta D.O. corresponde a la categoría de virgen extra y posee unas características organolépticas muy peculiares, derivadas del fruto de origen, la variedad «Arbequina» y de su cuidada elaboración. La aplicación en la zona de modemas técnicas de cultivo del olivo y las nuevas tecnologías de extracción del aceite, hacen necesario un estudio de su composición en campañas sucesivas, con el fin de determinar si la calidad se pudiera ver afectada. El presente trabajo se centra en la caracterización de los aceites producidos en la D.O. «Les Garrigues» durante la campaña 1995/96. Los aceites obtenidos presentan un grado de acidez medio de 0.17%, índice de peróxidos de 6.9 meq/kg de aceite y un K₂₇₀ de 0.21, valores todos ellos dentro de los criterios de calidad que establece la Reglamentación de la D.O. El contenido medio de polifenoles totales en el aceite es de 152 ppm, observándose una gran variabilidad entre las almazaras muestreadas. La concentración de clorofilas va de 15 mg/kg de aceite, al inicio de campaña, a 6 mg/kg al final de la misma. La concentración de carotenoides se reduce paralelamente, pasando de 12.6 a 4.6 mg/kg de aceite, al final de campaña. El color, en base a la escala visual ABT y a las coordenadas CIELAB, se mantiene dentro de los tonos del amarillo y no presenta diferencias importantes entre aceites de principio y final de campaña.

Full Text Available La disfunción sexual eréctil (DSE se define como la incapacidad que tiene un hombre para lograr y/o mantener una erección lo suficientemente adecuada para lograr una actividad sexual satisfactoria. La frecuencia de DSE es significativamente más elevada en la población diabética al compararla con la población general. El objetivo de este trabajo es hacer una revisión bibliográfica del tema DSE y diabetes mellitus (DM, y en él se incluyen los siguientes aspectos: anatomía del pene, aspectos fisiológico-clínicos y mecanismos patogénicos. Diferentes estudios señalan que la prevalencia de DSE en las personas con DM oscila entre el 20 y el 80 %, aunque esta varía en dependencia de la edad de los pacientes. En sujetos de 20 a 29 años, su prevalencia es del 9 %, y aumenta hasta un 90 % en aquellos que alcanzan los 70 años. La DSE se clasifica atendiendo a su causa en tres grupos: 1 orgánica, 2 psicógena y 3 mixta. Entre los factores patogénicos más relevantes se citan los neurológicos, los vasculares y los musculares, entre otros. La relajación del músculo liso de los cuerpos cavernosos y la erección del pene dependen de un complejo balance entre los eventos intracelulares y las señales extracelulares que controlan la contracción y la relajación del tono de las células musculares lisas de los cuerpos cavernosos. Las mediciones hemodinámicas y electrofisiológicas permiten evaluar con precisión la función sexual. El manejo terapéutico exige el control estricto y mantenido de los valores de glucemia. La DSE es una complicación frecuente en las personas con DM. Su etiología generalmente obedece a causas multifactoriales. Se impone desarrollar estudios clínico-epidemiológicos en muestra de población representativa, para conocer con precisión la magnitud de este problema. Su identificación temprana y el tratamiento adecuado determinarán una mejoría significativa de la calidad de vida de estas personas

Financial crises of the magnitude of that of 2007/2008 bring up important issues about financial markets. This paper investigates how distribution specification influences volatility modeling in the period including the financial crisis of 2007/2008.  Analysis was carried out by using weekly index data from the main stock exchanges of  BRIC (Brazil, Russia, India and China and the United States, using the APARCH model. The modeling is done in three subdivisions of  the sample considering six different distributions, normal, skewed normal, t-student, skewed  t-student, generalized and skewed generalized. Results of this research showed a variation in the distribution better adjusted during the crisis period, for almost all countries. Variation  in the distributions as well as in the significances and magnitudes of the coefficients can lead to the conclusion  that periods of financial oscillation and instability can influence the modeling of financial series, changing the magnitude and significance of coefficients, and be due to the  contagion  effect.La  crisis en el mercado inmobiliario norte-americano, en 2007, alcanzó estrechamente los mercados de capitales de los EEU y de los países europeos.

introducir Barcelona en el mercado de las Ciudades Globales. En estas ciudades se delega la producción de beneficios en el sector servicios en detrimento del industrial y se favorece la entrada ingente de capital inmobiliario, financiero y turístico. Nos encontramos pues con un proceso de tercerización que, a su tiempo, requiere una museización de la ciudad que la haga atractiva para los turistas e inversores inmobiliarios y financieros. Estas transformaciones –reconocidas bajo el epígrafe de Modelo Barcelona- no pretenden sólo modificar la morfología de la ciudad construyendo barrios residenciales, centros deportivos u hoteles, sino que aspiran a transformar los patrones culturales y mercantiles de sus habitantes hasta el punto, si es preciso, de sustituir los mismos vecinos por otros más a tono con estos nuevos escenarios en lo que se conoce como procesos de Gentrificación o Elitización. Dado que esta sustitución de hábitos y de habitantes no se ha producido “naturalmente” el consistorio, cediendo a diversos tipos de presiones ha instaurado un marco normativo proclive a la renovación estética y ética que se pretende. Se trata de un nuevo conjunto de normas que estrechen el abanico de formas de comportarse en el espacio público, de manera que afecte especialmente a cualquier sujeto que no responda a una especie de reglas universales de comportamiento –mimesis del saber estar de las clases medias de la ciudad. Esta reglamentación se encuentra recogida en el Proyecto de Ordenanza de medidas para fomentar y garantizar la convivencia ciudadana en la ciudad de Barcelona de noviembre de 2005, conocida popularmente como la Ordenanza cívica. Este texto problematiza el concepto de Espacio público y lo contrapone al de Multitud con la intención de poner en evidencia las correlaciones existentes entre estas transformaciones urbanas promovidas por las instituciones de gobierno y la conceptualización interesada dela noción de espació público.Download this

Vera Efigie

Puede usted yacer tranquilo y quieto
entre su tumba, ilustre doctor Zea:
al fin y al cabo la brillante idea
de retratarlo, ha sido de su nieto.

Qué mejor que, plasmado en un boceto,
colgarlo en el salón, como presea
de la Academia, en que brilló la tea
de su talento, lúcido e inquieto?

El problema, doctor, es el estilo;
la decisión pendiente está de un hilo
de retratarlo así, de cuerpo entero,
o, cediendo a atavismos de su gente
dejarlo a usted gordito y reluciente
en un cuadro …pintado por Botero.

En todo caso, sea que del soneto se derive o no una moraleja, sé que a Pacho le hubieran chocado los discursos. Hubiera preferido que habláramos en tono menor y un poco sonriente, como ahora, o como cuando nos conocimos desde siempre, hace ya 37 años, en los pabellones del Instituto Nacional de Cancerología.

This is the final report of the NUMO-LBNL collaborative project: Feature Detection, Characterization and Confirmation Methodology under NUMO-DOE/LBNL collaboration agreement, the task description of which can be found in the Appendix. We examine site characterization projects from several sites in the world. The list includes Yucca Mountain in the USA, Tono and Horonobe in Japan, AECL in Canada, sites in Sweden, and Olkiluoto in Finland. We identify important geologic features and parameters common to most (or all) sites to provide useful information for future repository siting activity. At first glance, one could question whether there was any commonality among the sites, which are in different rock types at different locations. For example, the planned Yucca Mountain site is a dry repository in unsaturated tuff, whereas the Swedish sites are situated in saturated granite. However, the study concludes that indeed there are a number of important common features and parameters among all the sites--namely, (1) fault properties, (2) fracture-matrix interaction (3) groundwater flux, (4) boundary conditions, and (5) the permeability and porosity of the materials. We list the lessons learned from the Yucca Mountain Project and other site characterization programs. Most programs have by and large been quite successful. Nonetheless, there are definitely 'should-haves' and 'could-haves', or lessons to be learned, in all these programs. Although each site characterization program has some unique aspects, we believe that these crosscutting lessons can be very useful for future site investigations to be conducted in Japan. One of the most common lessons learned is that a repository program should allow for flexibility, in both schedule and approach.

Sustancias como la Carbidopa y Levodopa, trajeron hace más de un decenio, renovadas esperanzas a los enfermos de Parkinson; desde hace un par de años los experimentos del grupo mexicano encabezado por el doctor Ignacio Madrazo (autoinjerto de médula suprarrenal en la cabeza del núcleo caudado y los intentos real izados en varios países para implantar en zonas del cerebro tejidos obtenidos de fetos, reabrieron las discusiones y avivaron las esperanzas de tratamiento quirúrgico, que habían comenzado con los éxitos de las lesiones talámicas estereotáxicas en las cuales fueron pioneros los doctores Tallairach y Cooper hace ya cuarenta años.

Como quinto volumen de la serie Neurological Diseases and Therapy (“Enfermedades neurológicas y su terapéutica” acaba de aparecer un libro en el cual se revisan los diversos aspectos de la enfermedad de Parkinson a la luz de los más recientes conocimientos y avances. Los doctores William C. Koller, del Departamento de Neurología de la Universidad de Kansas, y George Paulson, del Colegio de Medicina de la Universidad Estatal de Ohio, dirigieron el grupo de 70 científicos de todo el mundo (entre ellos, por supuesto, quienes trabajan en México y España que en 30 capítulos y 600 páginas pasan revista a los métodos de diagnóstico, los agentes farmacológicos, los métodos quirúrgicos, las medidas dietéticas, el tratamiento de la conducta y la terapia física para esta clase de enfermos.

y añadiduras, para poder alcanzar el resultado más apropiado en la intervención quirúrgica que se propone ejecutar; y la dosis, discutiendo la concentración, el volumen o la dosis gravimétrica, para poder obtener el resultado más adecuado, tanto en lo concerniente a la intensidad del bloqueo, como en lo que respecta a su duración. CONCLUSIONES: Los fallos son más inherentes a los factores técnicos: la evaluación anatómica adecuada, la elección de criterio de la aguja y del local de la punción, los cuidados en el almacenaje de los agentes, la adecuación de la dosis, la baricidad, además del posicionamiento correcto del paciente durante y después de la punción, todo a tono con el objetivo quirúrgico.BACKGROUND AND OBJECTIVES: Due to the discomfort caused to patients, failure of subarachnoid blocks that happen occasionally even when properly conducted be the most capable professionals have been described since Bier. However, the concept of failure and especially identification of the causes vary. The objective of this report was to identify the causes of this discomfort through a systematic review of publications with a significant number of patients. CONTENTS: The analysis was divided in three topics: anatomy and its variations; anesthetic agent, focusing on drug selection, its solutions, and additions to achieve the most appropriate result of the proposed surgery; and the dose, discussing concentration, volume, or gravimetric dose, to obtain the most adequate result regarding the intensity of the blockade and its duration. CONCLUSIONS: Failures are more commonly secondary to technical factors: adequate anatomic assessment, judicious choice of the needle and puncture site, care when storing the drugs, dose adequacy, and baricity, besides proper patient positioning during and after the puncture, and they all should be adequate for the surgical objective.

Research and development was carried out involving fine ceramic sintered body textural structure evaluation methods for the development of process technologies for achieving higher quality and lower cost. Studies centered about a method for evaluating coarse pores and coarse grains in sintered bodies, relations between sintered body fracture strength and textural structure, and the standardization of evaluation methods. As the result, an evaluation method for observing pore structures in a sintered body flake specimen under an optical microscope and another for observing coarse grains under a polarization microscope were proposed. As for the effect of coarse defects on the fracture strength of ceramics, it was demonstrated experimentally and theoretically that coarse defects several tens of micrometers in size greatly affected the fracture strength. In the study of methods for sintered body grain size evaluation, findings were obtained about the processing of the specimen surface. (NEDO)

Concerning the Manito Lowlands geothermal field and the Montelago geothermal field where the systems are to be newly installed, the geothermal reservoir characteristics are assessed, and cost effectiveness is compared between different power generating systems. According to the investigations conducted into the two geothermal fields in the past, they are supposed to have geothermal potentials of the medium grade. Chemical analyses are conducted anew on this occasion into the hot spring water and fumarole gas, and the MT (magnetotelluric) method is implemented for the survey of reservoir distribution. It is now expected that approximately 20MWe will be exploited from each of the two geothermal fields. The power generation systems studied are the single flash type and double flash type for the conventional power generation system, and the cascade type, bottoming type, and two-phase binary type for the combined binary power generation system. As the result, it is concluded that the double flash type or two-phase binary type will be advantageous to the Manito Lowlands geothermal field, and the double flash type or bottoming type or two-phase binary type will be advantageous to the Montelago geothermal field.

Uso del Propanolol en Hipertiroidismo

las manifestaciones de hipertiroidismo son de naturaleza hiperadrenérgica. Entre ellas están el nerviosismo, la hiperdiaforesis, en parte la intolerancia al calor, las palpitaciones, manifestaciones gastrointestinales, la taquicardia y/o fibrilación auricular, la piel caliente y húmeda, el soplo tiroideo o el temblor. El betabloqueo se traducirá en un rápido alivio de buena parte de la sintomatología (2.

Durante el manejo médico agudo del hipertiroidismo encontramos que el paciente tiene un aumento en la termogénesis y una respuesta exagerada a los estímulos beta-adrenérgicos, produciendo esto último nerviosismo y ansiedad, taquicardia y temblor. La terapia de apoyo para contrarrestar estos efectos incluye puntos tales como educación, mejoría del estado nutricional, reducción de las demandas cardiovasculares y el empleo de los betabloqueadores de los cuales el más usado es el propanolol.

Esta droga fue desarrollada por Sir James Black, recientemente galardonado con el Premio Nobel de Medicina. Se ha convertido en el prototipo de los beta-bloqueadores por la extensa experiencia clínica que de él se tiene. No es selectivo porque interactúa con igual afinidad con los receptores beta uno y beta dos; no bloquea los receptores alfa-adrenérgicos ni tiene actividad simpático-mimética intrínseca.

Al hacer el bloqueo, disminuyen proporcionalmente las respuestas cronotrópicas, inotrópicas y vasodilatadoras a la estimulación beta-adrenérgica; es altamente lipofílico y aunque se absorbe casi completamente cuando se da por vía oral, tiene un alto metabolismo de primer paso hepático y sólo un 25%llega a la circulación sistémica.

No existe una correlación simple entre el nivel plasmático o la dosis administrada y el efecto terapéutico y la gama de sensibilidad a las dosis utilizadas en clínica es amplia puesto que el tono simpático varía ampliamente entre individuos. Está contraindicado principalmente en asmáticos e

Full Text Available Trinta e um casos de polioencefalomalacia (PEM diagnosticados de 1999-2008 em bovinos do Sul (13 casos e Centro-Oeste (18 casos brasileiros foram estudados. As taxas de morbidade (0,04%-6,66 %, mortalidade (0,04%-6,66 % e letalidade (50%-100% foram semelhantes em ambas as regiões estudadas. Não houve uma associação clara entre os casos de PEM e a idade, sexo dos bovinos e sazonalidade. Os casos ocorreram principalmente em bovinos criados de forma extensiva em pastagem. Na Região Sul a doença afetou principalmente bovinos jovens (um ano de idade ou menos, enquanto que principalmente bovinos mais velhos (3 anos de idade ou mais foram afetados no Centro-Oeste. Os sinais clínicos mais frequentemente observados incluíram cegueira, incoordenação, andar em círculos, opistótono, decúbito e movimentos de pedalagem. A evolução do quadro clínico variou de 12 horas a 8 dias (media 3 dias e meio. Em 11 encéfalos não foram observadas alterações macroscópicas; as principais alterações macroscópicas nos outros casos incluíam congestão com tumefação e achatamento das circunvoluções, amolecimento e amarelamento do córtex telencefálico, focos de hemorragia no tronco encefálico, cerebelo e telencéfalo e herniação cerebelar. As principais alterações histológicas ocorreram no córtex dos lobos telencefálicos occipital, parietal e frontal; no entanto, lesões menos acentuadas e menos frequentemente observadas ocorreram no hipocampo, núcleos da base, tálamo, mesencéfalo e cerebelo. O tipo de lesão microscópica cortical era consistente em todos os casos e incluía necrose neuronal (neurônio vermelho laminar segmentar, espongiose, tumefação do núcleo das células endoteliais, astrócitos Alzheimer tipo II e infiltração por células gitter. Em 20% dos casos havia um leve infiltrado celular linfo-histiocitário e em 13% dos casos havia leve infiltrado de neutrófilos e eosinófilos. Adicionalmente, lesões necro

groundwaters, and also by stable isotopes and uranium isotopes in secondary minerals. Information on timing of water and solute movements is important because it indicates any correlation with the timing of external events that might have perturbed and destabilised the groundwater system in the past, and allows a timescale to be estimated for the persistence of stable conditions. Data from a number of published site investigation projects and research programmes are reviewed to illustrate the patterns of geochemical data and the relationships between them, and how these are interpreted in terms of hydrodynamic stability. Data from Aespoe and Stripa and from exploratory boreholes at Finnsjoen and other sites in Sweden are compiled and discussed. Preliminary data from SKB's ongoing site investigations at Simpevarp/Laxemar and Forsmark are not considered in detail but their general similarities with Aespoe and Finnsjoen/SFR respectively are introduced into the discussion of geochemical evidence for groundwater stability in inland and coastal areas. Relevant data from Finnish sites including Olkiluoto, from the Whiteshell URL area in Canada, from Sellafield in the UK, and from the Tono area and URL in Japan are also summarised in appendices and discussed because they add further insights into the interpretation of geochemical indicators for a range of geological environments. The compiled data provide only limited scope for comparison of groundwater evolution and stability between inland and coastal areas in Sweden, because of the patchiness of representative data especially from early site studies. The external changes that might have perturbed stable groundwater conditions in the past are glaciation (i.e. melt water, mechanical loading/unloading and permafrost) and varying sea water infiltration at coastal sites due to changes in palaeo-Baltic and isostatic conditions. The present distributions of palaeo-Baltic sea water in groundwaters at coastal sites vary, reflecting local

Full Text Available Monofluoracetato de sódio (MF foi identificado, por cromatografia, em três das doze plantas que causam morte súbita em bovinos no Brasil, incluindo Palicourea marcgravii, a mais importante desse grupo. Uma lesão considerada típica por alguns autores para intoxicação foi¹ a degeneração hidrópico-vacuolar dos túbulos uriníferos contorcidos distais (DHV. O objetivo deste trabalho foi verificar se a ingestão de MF induz sinais clínicos e lesões similares às observadas nos bovinos intoxicados pelas plantas que causam morte súbita. Seis vacas receberam, por via oral, 0,5 e 1,0mg/kg de MF diluídos em 50mL de água destilada. Clinicamente, os animais apresentaram taquicardia, jugular repleta com pulso venoso positivo, respiração abdominal, ligeira perda de equilíbrio, por vezes cambaleavam, deitavam e apoiavam a cabeça no flanco. Na fase final (agônica, todos os animais caíam em decúbito lateral, esticavam os membros, faziam movimentos de pedalagem, apresentavam opistótono, nistagmo, mugidos e a morte ocorria em 2-14 minutos. À necropsia verificaram-se aurículas, jugulares, ázigos e pulmonares moderadamente ingurgitadas. Observaram-se ainda leve a moderado edema da subserosa nos locais de fixação da vesícula biliar no fígado, além de leve edema entre o duodeno e o pâncreas. O exame histopatológico revelou, em todos os animais, desde leve a acentuada DHV das células epiteliais dos túbulos uriníferos contorcidos distais associada à cariopicnose. Com relação à ultraestrutura, observou-se vacuolização do citoplasma devido ao acúmulo de água. Vacuolização e necrose de coagulação individual ou de grupos de hepatócitos e leve congestão hepática secundários à estase venosa também foram observados. DHV tem sido observada em casos de envenenamento por outras substâncias, porém nestes não está restrita aos túbulos distais e não se observa cariopicnose. Este estudo demonstra que a DHV dos t
