    Described herein are the current status and development of insecticides for domestic purposes. For aerosol type cockroach-killing insecticides, oily type is predominant in Japan whereas aqueous type in USA and other countries. They are mixtures of knockdown agents and killing agents, the former being used for their immediate and lethal effects whereas the latter for their lethal effect. In 1996, agents showing high knockdown effects, such as pyrethroids, are registered. Fumigants are used in closed spaces, which are ventilated after they are used. Bait agents contain inducing agents. Recently, ticks become social problems as an allergy source. The insecticides are generally used to remove them, although physical methods, such as cleaning and heat treatment, are effective. They are centered by aerosols and fumigants, but insecticidal sheets are used to some extent. Fleas coming from pets also cause problems. Increased resistance of insects to insecticides has led to development of new types of insecticides, such as those based on organophosphates and those aimed at prevention of their metamorphosis. Commercial insecticides are safe, as long as they are produced in compliance with the Pharmaceutical Affairs Law and used correctly. Nevertheless, however, researches for safer countermeasures against insects are needed. 3 refs., 2 figs., 1 tab.

    The pig has an increasingly important role in ocular drug delivery models, but the most accurate tonometer in this species is unknown. The purpose of this study was to evaluate the accuracy of TonoVet and Tono-Pen Vet tonometers in the ex vivo porcine eye. Four freshly enucleated normal porcine eyes were cannulated with two 25-gauge needles; one connected via tubing to a mercury manometer calibrated continuous physiologic recorder and the other connected to a reservoir of lactated Ringer's solution on an adjustable stand. Triplicate IOP readings were taken with the TonoVet and then the Tono-Pen Vet at 5, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80 mmHg. Linear regression showed strong linear trends for both the TonoVet (r 2 = 0.969) and Tono-Pen Vet (r 2 = 0.983). The TonoVet slightly underestimated IOP at lower pressures and slightly overestimated IOP at higher pressures (y = 1.092x - 4.0, where y = tonometer reading, x = manometer reading, and 4.0 = intercept). The Tono-Pen Vet consistently underestimated IOP (y = 0.773x - 2.1). These differences were statistically significant (P = <0.001, one-way repeated-measures ANOVA). As in other species, both the TonoVet and Tono-Pen Vet tonometers do not measure true IOP in the porcine eye; however, the TonoVet more closely approximated true IOP in the normal porcine eye than the Tono-Pen Vet and may be the tonometer of choice for this species. © 2016 American College of Veterinary Ophthalmologists.

    The Tono-Pen is a miniaturized Mackay-Marg tonometer with electronic signal analysis and digital pressure display. In study 1, we compared the Tono-Pen with Goldmann tonometry in 108 healthy human subjects (216 eyes). In 33 of these subjects, the IOP was changed in a range between 0 and 50 mmHg by a scleral suction-cup system. In study 2, the Tono-Pen was compared with a Statham membrane manometer in 6 humans (12 eyes), 3-6h after death. The IOP was changed in a range between 0 and 60 mmHg by an infusion system. - Related to the Goldmann tonometer, the Tono-Pen gave a small overestimation of IOP below 16 mmHg (maximum deviation 1.5 mmHg at 0 mmHg Goldmann reading). Above 16 mmHg, however, the Tono-Pen increasingly underestimated the IOP determined by Goldmann tonometry (maximum deviation 8 mmHg at 50 mmHg Goldmann reading). Related to the manometer, the Tono-Pen gave a small overestimation of IOP below 17 mmHg and small underestimation above 17 mmHg (maximum deviation 2.5 mmHg at manometer readings of 0 and 60 mmHg, respectively). - Throughout the entire clinically relevant IOP range, an acceptable relationship between Tono-Pen and manometer readings was found in human cadaver eyes, whereas the relationship between Tono-Pen and Goldmann tonometric readings in the clinical study was found to be acceptable only in the low and physiological IOP range. The considerable deviation from the Goldmann readings in the high IOP range requires further modifications of the Tono-Pen.

    Tono-Pen and TonoVet have been used in rabbits to measure intraocular pressure (IOP) and investigate the effect of IOP lowering therapies. Therefore, their reliability and accuracy are very important and deserve careful evaluation. Our results showed that the with-subject deviation (S w ) and intraclass correlation coefficient (ICC) of the TonoVet and Tono-Pen were 0.61 mmHg/0.83 mmHg and 0.97/0.94, respectively for intrasession repeatability. For intersession reproducibility, the Sw and ICC of TonoVet and Tono-Pen were 1.42 mmHg/1.66 mmHg and 0.73/0.67, respectively. For interoperator reproducibility, the S w and ICC of the TonoVet and Tono-Pen were 0.72 mmHg/1.11 mmHg and 0.91/0.82 respectively. Both TonoVet and Tono-Pen underestimated the IOP measured by manometry. The regression function was: y = 0.8249x + 0.1011 and y =0.6881x + 2.2290 for TonoVet and Tono-Pen, respectively. Our study suggests that both TonoVet and Tono-Pen had excellent intrasession repeatability and inter-operator reproducibility, but good intersession reproducibility. Both TonoVet and Tono-Pen correlated well with manometry, but underestimated the manometric IOP with presence of fixed and proportional biases. These factors should be considered when measuring IOP with Tono-Pen or TonoVet in rabbit eyes.

    Tono-Pen and Goldmann tonometers were compared in 152 eyes of healthy subjects (Group A) and 69 eyes of patients after intraocular procedures (Group B). In Group A, the readings from both the tonometers showed no statistically significant difference in the 0 to 15mmHg range. However, the Tono-Pen values were lower in eyes with intraocular pressures between 16 and 30mmHg (P less than .0001). This questions the reliability of Tono-Pen as an adequate screening instrument. The correlation between the two instruments was acceptable in Group B (r = .89), indicating that the Tono-Pen may be used cautiously to determine intraocular pressure in postoperative patients.

    To compare scleral Tono-Pen (Medtronic Solan, Jacksonville, FL) readings to corneal Tono-Pen readings. Intraocular pressure (IOP) was measured prospectively in 72 eyes of 37 adult patients and in 10 eyes of 5 children. Measurements were taken on the central cornea and on the sclera. Recorded measurements were within 5% confidence levels by Tono-Pen. Corneal IOP ranged from 10 to 28 mm Hg (mean +/- standard deviation, 17.0 +/- 3.8 mm Hg). Scleral measurements ranged from 4 to 99 mm Hg (40.4 +/- 23.0 mm Hg). Scleral measurements ranged from 11 mm Hg lower to 76 mm Hg higher than corneal measurements. Tono-Pen readings obtained from sclera are of no clinical value and should not be used to approximate corneal IOP.

    A Tono-Pen-1 (TP-1) and a Tono-Pen-2 (TP-2) were calibrated against direct manometry in the eyes of living rabbits to determine the accuracy of the Tono-Pen. Eighteen normal eyes of 10 rabbits were cannulated and connected to a pressure transducer with a chart recorder. Intraocular pressure (IOP) was increased from 5 to 40 mm Hg in 5-mm-Hg increments and from 40 to 80 mm Hg in 10-mm-Hg increments. After each incremental increase, IOP was measured first with a TP-1 and then with a TP-2. Plotting the mean Tono-Pen readings for each eye against the transducer pressure produced the following two regression line formulas: y = -0.613+0.790x (r2 = 0.97) for TP-1, and y = -1.45+0.824x (r2 = 0.97) for TP-2. Neither regression line was statistically different; p = 0.2 for the two slopes, and p = 0.24 for the y-axis intersection. The TP-1 and TP-2 can be used to rapidly and accurately measure the IOP in normal rabbit eyes. Tono-Pen readings do, however, significantly underestimate pressures in the range of 5-80 mm Hg. A table with 95% confidence intervals for corrected IOP readings obtained with the TP-1 or -2 is provided.

    A clinical evaluation of two new portable tonometers, the Oculab Tono-Pen and the Keeler Pulsair, was performed to determine their accuracy and efficacy. Measurements were obtained in 229 eyes of 130 normal patients and compared to measurements obtained with the Goldmann applanation tonometer. The average absolute deviation for the Tono-Pen and the Pulsair was a significant 2.70 mm Hg and 2.49 mm Hg, respectively. Thirteen of 188 (7%) Tono-Pen readings and 19 of 229 (8%) Pulsair readings differed from the Goldmann readings by more than 5 mm Hg. Both instruments were highly sensitive and specific for detecting intraocular pressures greater than 21 mm Hg.

    To evaluate the intraocular pressure (IOP) measurements in patients with band keratopathy or glued corneas obtained from affected and non-affected areas. 15 patients with band keratopathy or glued corneas were prospectively recruited. When both eyes were affected, only the right eye was analysed. Tono-Pen readings of IOP were obtained sequentially from the affected and non-affected corneal surface. Additionally, Goldmann applanation tonometry was attempted. Determination of IOP with the Tono-Pen was possible in all cases, while Goldmann tonometry was not performed in three patients because of severe corneal irregularities. The average of the Tono-Pen readings obtained from the affected cornea (34.8 (SD 14.0) mm Hg) was consistently and significantly higher (p < 0.001) than mean IOP obtained by the Tono-Pen from the non-affected area (14.8 (4.3) mm Hg). The average of Goldmann tonometry readings (14.4 (6.1) mm Hg) did not differ significantly from the Tono-Pen values obtained from the non-affected corneal area (p = 0.47) but was significantly lower than the Tono-Pen measurements obtained from the affected area (p < 0.001). In patients with band keratopathy or glued corneas determination of IOP by Tono-Pen tonometry varies from affected to non-affected area. The Tono-Pen overestimates the level of IOP when it is applied to areas with band keratopathy or with glue.

    Full Text Available Abstract Background The purpose of this study is to evaluate the use of Tono-Pen XL in measuring IOP during the application of a suction ring in rabbit eyes with manometrically controlled IOP. Methods Tono-Pen XL was calibrated against direct manometry in 10 rabbit eyes. A suction ring was then applied in 4 rabbit eyes and the IOP was determined manometrically during suction ring application at 350 mmHg vacuum pressure. Finally, in 6 catheterized rabbit eyes the IOP was measured with Tono-Pen XL during suction ring application at suction vacuum from 350 to 650 mmHg, while keeping actual IOP stable at 30 mmHg and 60 mmHg. Results Linear regression analysis revealed that the Tono-pen XL was reliable for IOPs between 10 and 70 mmHg (R2 = 0.9855. Direct manometry during suction ring application showed no statistically significant variation of Tono-Pen XL readings when the incanulation manometry intraocular pressure changed from 30 mmHg to 60 mmHg and no statistically significant correlation between suction vacuum and IOP measurements. Conclusion Tono-Pen XL measurements are unreliable during the application of a suction ring on living rabbit eyes even when the actual IOP is forced to be within the validated range of Tono-Pen XL measurements. This inaccuracy is probably related to altered corneal and scleral geometry and stress.

    2010-09-01

    To examine the accuracy and reproducibility of intraocular pressure (IOP) measurements obtained by the TonoVet rebound tonometer. Animals studied  Freshly enucleated healthy eyes of 44 free-ranging birds of prey out of the species Haliaeetus albicilla, Accipiter gentilis, Accipiter nisus, Buteo buteo, Falco tinnunculus, Strix aluco, Asio otus and Tyto alba euthanized because of unrelated health problems. IOP readings from the TonoVet were compared with a manometric device, with IOP being set from 5 to 100 mmHg in steps of 5 mmHg by adjusting the height of a NaCl solution reservoir connected to the eye. Reproducibility of the TonoVet readings was determined by repeated measurements. TonoVet and manometer values showed a strong linear correlation. In the Accipitridae, the TonoVet tended to increasingly overestimate IOP with increasing pressure, while in the other families, it increasingly underestimated it. In the Sparrowhawk, the values almost represent the ideal line. Reproducibility of TonoVet values decreases with increasing pressure in the clinically important range from 5 to 60 mmHg. IOP values measured with the TonoVet demonstrated species specific deviation from the manometric measurements. These differences should be considered when interpreting IOP values. Using the regression formulae presented, corrected IOP values could be calculated in a clinical setting.

    Tono Geoscience Center, Japan Nuclear Cycle Development Institute has been conducting a wide range of geoscientific research in order to build a firm scientific and technological basis for the research and development of geological disposal. One of the major components of the ongoing geoscientific research programme is the Regional Hydrogeological Study (RHS) project in the Tono region, central Japan. The main goal of the RHS project is to develop and demonstrate surface-based investigation methodologies to characterize geological environments on a regional scale in Japan. The RHS project was initiated in 1992. To date, remote sensing, geological mapping, airborne and ground geophysical investigations, and measurements in eleven deep boreholes have been carried out in the study area (c. 100 km{sup 2}). Groundwater chemistry and hydraulic head monitoring is under way in these boreholes. Important results that have been obtained from these investigations include various information concerning the heterogeneity of lithological, hydrogeological and geochemical, and evolution of the groundwater geochemistry. During fiscal year 2001, hydraulic testing and groundwater sampling were conducted in borehole DH-13 which was drilled during fiscal year 2000. High density electrical resistivity measurements were conducted on a lineament. Groundwater monitoring was continued in the existing boreholes. As a part of evaluation of data uncertainties for modeling and simulation, study was started with the purpose of setting of modeling and simulation area around MIU constructionsite. Development of investigation instruments were also continued. (author)

    The purpose of the study was to determine if Tono-Pen tonometers use simple average and coefficient of variation (CV) algorithms to calculate intraocular pressure (IOP). IOPs were measured as part of routine ocular examination in 152 client-owned dogs. Using 11 Tono-Pen's, a total of 778 averaged readings were collected. Individual IOP readings, and average IOP and CV displayed by the instrument, were recorded. Average IOP and CV were then manually calculated from individual readings and compared with those displayed by the instrument. The mean absolute difference between the calculated and displayed average IOP was 1.37±2.01 mm Hg (P20%, but displayed CV was <5%. Receiver operating characteristic analysis could not correlate number of individual IOP readings with magnitude of difference in average IOP. Calculated average IOP and CV differ significantly from values displayed by the instrument, especially at higher IOPs. A difference of ≥5 mm Hg between calculated and displayed average IOP seen in 6% of cases may impact clinical judgement. Displayed CV<5% does not correlate with accurate IOP measurement based on individual results.

    This data book is the revised edition of the previous data book, made by Iwatsuki et al. (2001). Chemical data of groundwaters from 5 boreholes (MIU-4, DH-2, DH-3, MSB-2 and MSB-4) and those for onsen (spa) (Mikai and Hayakawa, 1970) are added to the previous edition. This data book presents the chemical data for groundwaters, surface waters and rain waters in the Tono area, obtained up to the beginning of April 2003. Compositions for about 350 waters are tabulated. These data were acquired over a period of more than 15 years, during many different studies that had various purposes. The data were obtained through the uranium exploration, the hydrochemical investigation within and around the Tono Mine, the regional hydrogeological study and the hydrochemical investigations within the Shobasama site and the MIU (Mizunami Underground Research Laboratory) construction site. While considerable effort has been expended to transcribe data correctly from the various sources, a care must be taken to read the data because of uneven quality in the data due to different methods of sampling and analyzing. Therefore report indicates the data sources, the geographical locations where the data were obtained and the main sampling and analytical methods respectively in order to reconfirm the suitability of the data for each appraisal purpose.

    This report summarizes the research result about geochemical modelling of the groundwater during H14 financial year. JNC-TGC have built the geochemical conceptual models of groundwater by using the chemical data of the groundwater of the Mizunami group and Toki granite. Although this models are extremely useful as interpretive tools, they lack the quantitative basis necessary to evaluate coupled processes of fluid-flow and water-rock interaction driving the chemical evolution of groundwater systems. In this research, the following three items have been considered for the purpose of construction of the geochemical model which can express the chemical reaction in groundwater correctly. Evaluation of the quality of the previous analytical data in the Tono region. Grasp of the chemical character of groundwaters. Consideration about the influence between Eh, pH and CO 2 (g) parameter, and which the change has. Evaluation of the quality of the previous analytical data are important because deficiencies in sampling technique, sample-preservation procedures or analytical method may adversely affect the overall quality of groundwater chemical and isotopic analysis. In addition, the effects of borehole drilling and logging, hydraulic testing inappropriate sampling strategies or inadequate sampling tools may perturb groundwater compositions to such an extent that they are unrepresentative of in-situ conditions. The quality of water analysis is indicated by its charge balance. The charge balance of many of the analysis lies within the strictly acceptable range of 0±5%, but charge imbalances exceeding these limits are calculated for many other samples. These reasons are examined in the following. Analytical errors (e.q., of alkalinity). Errors arising from the use of IC values that are unrepresentative because CO 2 was gained by or lost from the sample during storage and (or) analysis. Errors arising from the invalid assumption that non-carbonate contributions to the

    The present status of the JNC Tono Geoscience Center AMS system (TGC-AMS) and the recent developments for 14C and 10Be are summarized. The preparation system for 14C has been modified to enable the preparation of small samples. The precision for 14C measurements with samples having a carbon mass >0.3 mg was normally within 0.5%. For the 10Be analysis, the detector of the AMS system has been improved by mounting a nitrogen absorber together with Havar windows in order to suppress 10B isobars. The efficient separation of 10B from 10Be was demonstrated by comparing the rest energy spectra of a 10Be standard and a mutually 10Be-free sample material.

    The present status of the JNC Tono Geoscience Center AMS system (TGC-AMS) and the recent developments for {sup 14}C and {sup 10}Be are summarized. The preparation system for {sup 14}C has been modified to enable the preparation of small samples. The precision for {sup 14}C measurements with samples having a carbon mass >0.3 mg was normally within 0.5%. For the {sup 10}Be analysis, the detector of the AMS system has been improved by mounting a nitrogen absorber together with Havar windows in order to suppress {sup 10}B isobars. The efficient separation of {sup 10}B from {sup 10}Be was demonstrated by comparing the rest energy spectra of a {sup 10}Be standard and a mutually {sup 10}Be-free sample material.

    Tono Geoscience Center, Japan Nuclear Cycle Development Institute has been conducting a wide range of geoscientific research in order to build firm scientific and technological basis for the research and development of geological disposal. One of the geoscientific research programme is a Regional Hydrogeological Study (RHS) project in the Tono region, central Japan. This report mainly summarizes the results of research in DH-14 and DH-15 boreholes at Toki city and Mizunami city in fiscal year 2004 which were carried out to support and improve the results in fiscal year 2003. The research in the regional scale area shows the reliability of conceptual hydrogeological model and numerical simulation for the evaluation of regional hydrogeology. On the other hand, the geological and geophysical investigation, and borehole investigation during the surface-based investigations in the local scale area provide the pragmatic distribution of hydrogeological structure that may control regional groundwater hydrology. Hydrogeological simulations regarding the geological structure such as fault and hydrogeological property demonstrate the priority of investigation of geological structure for the evaluation of hydrogeology. The fault perpendicular to groundwater flow direction crucially affects on regional hydrology. Such fault is necessary to be investigated by priority. Hydrochemical investigation shows that chemical evolution process in this groundwater illustrated is mixing between groundwaters with different salinities. Principal component analysis and mass balance calculation reveal reliable chemistry of end-member waters for mixing. Regarding methodology development, the strategy and procedure of investigations are summarized based on the results of surface-based investigation. Moreover the multi interval monitoring system for water pressure and temperature has developed and started to monitor the in-situ condition of groundwater.

    To experimentally examine the effect of increased corneal stiffness on Goldmann applanation tonometry (GAT) and Tono-Pen (Reichert, Inc., Depew, NY) measurements of intraocular pressure (IOP) in a canine eye model. Twenty globes were recovered from 10 dogs with no known diseases. For each dog, corneal stiffening was induced in one eye with glutaraldehyde/phosphate buffered saline (PBS) immersion while the other cornea was immersed in PBS only. Acoustic impedance was measured before and after treatment in all eyes. After treatment, IOP was measured by GAT and Tono-Pen at true pressures of 10, 15, 20, 30, and 40 mm Hg. The corneas were then dissected for uniaxial tensile testing. The GAT/Tono-Pen readings, corneal stiffness (measured by ultrasound and tensile tests), and corneal thickness were compared between the two groups. The correlations between GAT/Tono-Pen readings and corneal stiffness were evaluated. Acoustic impedance significantly increased after glutaraldehyde treatment (P < 0.01). Secant modulus at 1% strain was significantly higher in corneas treated with glutaradehyde/PBS than those treated with PBS only (P < 0.01). GAT and Tono-Pen readings were significantly higher at all pressure levels (P < 0.001) in the eyes with corneal stiffening. Both corneal acoustic impedance and secant modulus were significantly correlated with GAT/Tono-Pen readings at all pressure levels (P < 0.01). This study provided experimental evidence that corneal stiffening significantly increases GAT and Tono-Pen readings in canine eyes. Noninvasive ultrasound measurement of acoustic impedance may be used to evaluate corneal stiffness and improve the accuracy of clinical measurements of IOP.

    To compare Tono-Pen AVIA (TPA) intraocular pressure (IOP) measurements performed at the limbus with central corneal Tono-Pen AVIA (TPA) intraocular pressure. Fifty-one patients attending our outpatient department with a best corrected visual acuity of ≥ 20/40, no corneal disease, and no astigmatism greater than 1.5 diopters underwent routine ophthalmological examination. Patients with ametropia greater than or equal to ± 5 diopters, a history of recent contact lens wear, and central corneal thickness of 550 µm were excluded from the study. IOP was recorded first in the corneal center, followed by tonometry measurements obtained from the temporal, nasal, superior, and inferior limbus using TPA. IOP measurements were compared using the paired t test. Correlation was derived by Pearson correlation coefficient, and regression equations were derived. The mean age of patients in our study was 43.86 ± 15.39 years. The mean TPA IOP from the central cornea was 16.59 ± 3.75 mm Hg. There was a statistically significant difference between Tono-Pen IOP from the central cornea and that recorded from all 4 limbal positions (P < 0.001). There was a positive correlation between the central and the limbal IOP obtained with Tono-Pen. Correlation was maximum for the temporal limbus. Limbal TPA IOP is significantly higher than central TPA IOP. There remains a good correlation between central and limbal IOP. This was found to be greatest for the temporal limbus.

    To compare the Tono-Pen tonometer with the Goldmann applanation and assess the precision and accuracy of the Tono-Pen tonometer. 62 cases (111 eyes) were random measured with the Tono-Pen tonometer and the Goldmann applanation tonometer. Overall we found that 74.8% of the Tono-Pen readings were within +/- 2 mmHg of the Goldmann applanation readings and 83.8% were within +/- 3 mmHg. The correlation coefficient between the readings of the two instruments was 0.865. The mean value of the paired differences was (-0.51 +/- 2.24)mmHg in the 9 to 30 mmHg interval. The Tono-Pen tonometer measures intraocular pressure in a manner that corresponds well to the Goldmann applanation tonometer, especially in the 9 - 30 mmHg interval. But this tonometer may overestimate the intraocular pressure in eyes with low intraocular pressure, and underestimate the intraocular pressure in eyes with high intraocular pressure.

    To evaluate the reproducibility of two portable tonometers and to compare the intraocular pressure (IOP) measurements obtained with both instruments taking into account the level of experience of the examiner with this technique. Cross-sectional study. IOP was measured in 35 eyes of 35 normal subjects and 20 eyes of 20 ocular hypertensive patients with Perkins aplanation tonometer and Tono-Pen XL digital tonometer. Five measurements were made with Perkins (by an ophthalmologist) and 10 with Tono-Pen (5 by an ophthalmologist and 5 by a general practitioner). Considering the sample as a whole there was no statistically significant difference, and there was a significant correlation between the mean measurements obtained with Perkins tonometer and Tono-Pen and between the mean obtained by doctors with and without previous tonometric experience (p or =21 mmHg with a sensitivity of 40% and a specificity of 94-97%. Tono-Pen allows measurement of IOP to personal with no tonometric experience. There is a strong correlation between measurements obtained with both tonometers. Tono-Pen shows a tendency to underestimate high IOP and offers low sensitivity in detecting IOP greater than 21 mmHg.

    To estimate agreement between measurement of intraocular pressure (IOP) by the Tono-Pen and by the Goldmann tonometer. The hypothesis tested was that the mean difference in measurements would be or =25 mmHg), the mean difference between instruments (Tono-Pen reading minus Goldmann reading): was -4.2 mmHg (P = 0.0004), SD: 4.6, 95% limits of agreement: -13.2 to 4.8 mmHg and ICC = 0.76. Combining the analysis for both groups, the Tono-Pen significantly underestimated the IOP when the pressure was >20 mmHg. The Tono-Pen cannot replace the Goldmann tonometer in the sense that it will give the same readings of IOP. The accuracy of the Tono-Pen is increased, if at least two measurements are taken per eye and then averaged.

    Measuring the intraocular pressure (IOP) in children can be difficult. We compared the accuracy of IOP measurements in pediatric patients using three tonometers: Perkins, Schiötz, and Tono-pen. Seventy-seven children (132 eyes; average age, 1 year, 7 months; range, 1 month to 60 months), mainly afflicted with retinopathy of prematurity (107 eyes), were evaluated. A good correlation (r = 0.867) was found between the Tono-pen and the Perkins tonometers. No statistical difference was found between the mean difference of IOP values obtained with the Tono-pen and the Perkins (P > .05). The Schiötz measurements were significantly higher than those obtained with the Perkins and the Tono-pen tonometers (P < .05). We concluded that the Tono-pen tonometer has a higher correlation coefficient, comparable to the Perkins tonometer, and can be used reliably to assess IOP in pediatric patients.

    A human monoclonal antibody (HuMab) TONO-1 (IgM, lambda) recognizes cell surface antigens associated primarily with human T-leukemia/lymphoma cells. In this study, we investigated the reactivity against T-leukemia/lymphoma cells in detail, cytotoxic potential and primary nucleotide and deduced amino acid sequences of the rearranged heavy and light chains of the HuMab TONO-1. Expression of the molecules (TONO-1 Ags) detected by a HuMab TONO-1 was significantly heterogeneous even in the same T-leukemia/lymphoma cell lines HPB-MLT and MOLT-4F. The flow cytometric curves showed an unusual broad-based spread of fluorescence intensity. HuMab TONO-1 was shown to have the ability to kill the T-leukernia/lymphoma cells efficiently in the presence of rabbit complements. However, HuMab TONO-1 did not demonstrate significant antibody-dependent cellular cytotoxic activity. Furthermore, HuMab TONO-1 heavy and light chain variable regions were cloned, sequenced and analyzed. HuMab TONO-1 uses a V(H) gene member of the V(H)IV gene family V(H)71-4, and is productively rearranged with the germ line D(H) gene D(XP')1, and the germ line J(H)5 gene with multiple somatic mutations. HuMab TONO-1 Vlambda belongs to the lambda light chain variable subgroup I family and is derived from the Vlambdalc germ line gene Humlv1042, and germ line gene Jlambda1 without somatic mutations. The results reveal that the production of HuMab TONO-1, with cytotoxic potential for human T-leukemia/lymphoma cells, is achieved by rearrangement of the V(H)71-4/Humlv1042 germ line variable region gene combination, that is associated with the autoimmune repertoire.

    As the awareness of the influence of central corneal thickness (CCT) on Goldmann tonometry has increased, many publications have questioned the accuracy of Goldmann intraocular pressure (IOP) measurement. The Tono-Pen, because it indents a much smaller surface area when compared to a Goldmann probe, may be less affected by corneal thickness variations when compared with Goldmann tonometry. Forty human subjects with no history of refractive surgery participated in this study. The IOP of the right eye of each subject was measured with the Goldmann tonometer, the Tono-Pen at the central cornea, and the Tono-Pen at the mid-peripheral cornea. An ultrasonic DGH Pachette pachymeter was used to measure the central and mid-peripheral corneal thickness at the location of the IOP readings. Tono-Pen measurements at the central and mid-peripheral cornea highly correlated (r = 0.933), and did not significantly differ (p = 0.646). The IOP readings with the Goldmann tonometer (r= 0.406), the Tono-Pen at the central cornea (r = 0.453), and the Tono-Pen at the mid-peripheral cornea (r = 0.321) showed a positive correlation to corneal thickness. The Goldmann and Tono-Pen tonometers differed significantly in the measurement of IOP at the central cornea (p = 0.007), but were positively correlated (r = 0.674). The Tono-Pen IOP measurement at the central cornea highly approximated Tono-Pen IOP measurement at the mid-peripheral cornea. Furthermore, although not highly correlated, both the Goldmann and Tono-Pen tonometers showed a significantly positive correlation between IOP and corneal thickness measurements.

    To compare the TonoVet(®) rebound tonometer with the Tono-Pen Vet(®) applanation tonometer in a larger number of glaucomatous eyes and to evaluate the effect of different corneal pathologies on both tonometers. In 26 eyes with clinical signs of glaucoma, intraocular pressure (IOP) was measured using the TonoVet(®) followed by the Tono-Pen Vet(®) . In 29 eyes with focal corneal pathology (e.g., corneal scarring, edema, pigmentation), both tonometers were used successively to measure IOP in one unaffected area of the cornea, as well as on the lesion itself. Impact on measurement results was assessed comparing the deviation in IOP readings of each tonometer between the two localizations. Statistical data analysis included paired t-tests and regression analysis using sas software (version 9.2; SAS Institute, Cary, NC). In glaucomatous eyes, the TonoVet(®) consistently yielded higher values of IOP than the Tono-Pen Vet(®) as can be quantified by the regression equation IOP (TonoVet(®) ) [mmHg] = 1.12 * IOP (Tono-Pen Vet(®) ) [mmHg] + 11.5 with R(2) = 0.91 and P < 0.0001. Depending on the type and degree of corneal pathology, the deviation in IOP resulting from measurements on altered cornea ranged from -6 to 16 mmHg for the TonoVet(®) and -7 to 20 mmHg for the Tono-Pen Vet(®) , respectively. On average, the effect of corneal disease on IOP measurements was lower for the TonoVet(®) by 1.14 mmHg. Rebound tonometry appears to be a valuable alternative to established applanation tonometry in patients with ocular disease such as glaucoma and corneal disorders. In patients suffering from glaucoma, the same type of tonometer should be used for follow-up examinations, as measurement results of the TonoVet(®) and the Tono-Pen Vet(®) differ substantially with increasing IOP. Corneal pathology has considerable influence on both tonometers with the degree of over- or underestimation of IOP depending on the alteration of biomechanical properties of the cornea inflicted

    To evaluate the validity and intraobserver reliability of intraocular pressure (IOP) measurements with both pneumotonometry and the Tono-Pen in a closed ex vivo system in cat eyes. IOP was increased step by step in 5 enucleated cat eyes, while taking IOP measurements with the Tono-Pen and pneumotonometry. The outcomes were compared to readings of a digital manometer simultaneously measuring the actual pressure in the anterior chamber. Pneumotonometry overestimated IOP below 15 mm Hg and underestimated pressures above 20 mm Hg. Tono-Pen tonometry considerably underestimated IOP over the whole spectrum in all of the eyes tested. The pneumotonometer was identified as the more valid and reliable instrument for cat eyes. Both tonometers are clinically useful tools to assess IOP for glaucoma studies using a cat animal model. However, one has to consider underestimation of IOP in the upper ranges. A correction formula can be used to calculate the actual IOP.

    Reproducibility of measurements of postural changes in intraocular pressure was determined by using the Tono-Pen (Mentor O & O, Inc., Norwell, Massachusetts) and Pulsair (Keeler Instruments, Inc., Broomhall, Pennsylvania) tonometers. Thirty subjects had three repeated sitting and reclining measurements performed on three separate visit days. Reproducibility coefficients of 3.3% for the Tono-Pen and 6.3% for the Pulsair were obtained for the within-visit postural change measurements. Across-visit reproducibility coefficients were 7.9% and 26.2% for the Tono-Pen and Pulsair, respectively. The estimated standard deviations for both the within-visit and across-visit postural change measurements were high for both instruments. These results indicate poor reproducibility of measurements of postural changes in intraocular pressure.

    To report an accuracy of intraocular pressure (IOP) by Tono-Pen XL over amniotic membrane patching in rabbits. Experimental study. Seven male albino rabbits were used in this study. After general anesthesia, IOP was measured in both eyes using the Tono-Pen without amniotic membrane. A single layer amniotic membrane was then immediately placed over the rabbit eye, and the IOP measurement was repeated. The average IOP without amniotic membrane was 5.8 +/- 0.6 mm Hg (mean +/- SD). The average IOP through amniotic membrane was 6.0 +/- 0.4 mm Hg (mean +/- SD). There was no statistical difference in IOP measured on corneas with or without the amniotic membrane (P =.34). The accuracy of IOP measurement by Tono-Pen XL over a single layer of amniotic membrane patching was demonstrated using rabbit eyes. Further studies in human eyes may verify our findings in actual clinical settings.

    We evaluated a miniaturized digital and electronic tonometer, the Tono-Pen, for accuracy of intraocular pressure measurement in the presence of a contact lens. In the manometric study, the Tono-Pen was used to measure a known intraocular pressure, ranging from 10 mm Hg to 60 mm Hg in a cadaver eye over soft contact lenses with different powers and a plano-T bandage lens. There was significant bias in pressure measurement over all contact lenses except for the plano-T, which had no bias at any level. In the clinical study, the intraocular pressures of 40 eyes in 20 normal patients were measured with and without a plano-T contact lens in place. Analysis of variance showed no significant interactive effect between the right and left eyes, with or without the lens. There was no significant difference in the Tono-Pen measurement of intraocular pressure over a plano-T contact lens compared with no lens.

    Tonometry in the anesthetized child, vital for evaluating known or suspected glaucoma, remains limited to tonometers capable of supine recording. The Icare PRO measures intraocular pressure (IOP) in the sitting or supine patient. The purpose of this study was to compare Icare PRO and Tono-Pen tonometry during examination under anesthesia in eyes of supine children with normal eyes and glaucoma and/or corneal pathology. In this prospective study of children undergoing examination under anesthesia, IOP was recorded in both eyes with Icare PRO and Tono-Pen immediately after mask anesthesia induction, with instrument order randomized. A total of 100 eyes of 50 children (median age, 58 months) were included. IOP range was 6-50 mm Hg by Icare PRO and 6-53 mm Hg by Tono-Pen. Mean IOP measured by Tono-Pen (18.9 ± 7.5) was higher than that measured by Icare PRO (16.7 ± 7.1 mm Hg) by 2.2 mm Hg (P < 0.001). The presence of corneal edema was associated with IOP measurements higher by Tono-Pen than by Icare PRO (mean difference, 8.4 mm Hg). When eyes with corneal edema were excluded from analysis, there was no correlation between central corneal thickness and the difference in IOP between the two instruments. IOP in eyes of supine children under anesthesia measured approximately 2 mm Hg higher by Tono-Pen than Icare PRO and this difference was greater in eyes with frank corneal edema. Icare PRO may become a valuable tool for tonometry in supine infants and children, but a confirmatory test should be considered in eyes with corneal edema.

    2005-08-01

    We sought to compare intraocular pressure (IOP) measurements by Perkins tonometer and Tono-Pen in young children with primary congenital glaucoma (PCG). This was a retrospective comparative case series. We reviewed the clinical records of all children with primary congenital glaucoma who underwent examinations under general anesthesia at Soroka University Medical Center between January 1999 and July 2002. Our main outcome measures were IOP with Perkins hand-held tonometer and Tono-Pen tonometer. A total of 28 eyes of 16 children were examined under general anesthesia. The mean IOP was 18 +/- 6 mm Hg with the Perkins tonometer and 22 +/- 8 mm Hg with the Tono-Pen. In 18 eyes, IOP was less than 21 mm Hg with the Perkins tonometer; these eyes had already undergone surgical procedures. The other 10 eyes with IOP greater than 21 mm Hg with the Perkins tonometer underwent surgery at the end of the examination under anesthesia. In eyes with IOP greater than 16 mm Hg (Group A, n = 18), a significant difference (P < 0.001) was found between the Perkins and Tono-Pen measurements, even although the values were strongly correlated (r = 0.60). In contrast, in eyes with IOP less than 16 mm Hg (Group B, n = 10) no statistically significant difference (P = 0.28) and good correlation (r = 0.78) were obtained. A difference of 5.8 +/- 3.8 mm Hg and 0.6 +/- 1.7 mm Hg between Perkins and Tono-Pen readings, respectively, was found in Groups A and B. Tono-Pen readings disagree with Perkins tonometer measurements for measuring IOP in children with PCG who present with IOP greater than 16 mm Hg and tends to overestimate IOP. A further study with a similar population is necessary to confirm these results.

    The objective of this study was to provide calibration curves for correcting intraocular pressure (IOP) measurements obtained using the Tono-Pen XL tonometer in cats, cows and sheep. Twelve eyes from 9 cats, 13 eyes from 7 cows, 10 eyes from 5 sheep were used. The anterior chamber of the eye was cannulated in vivo, in situ (immediately post mortem) or ex vivo with a fine needle and IOP was varied from 10 to 90 mmHg in steps of 10 mmHg by adjusting the height of a saline reservoir connected to the needle. For each pressure setting, several readings of IOP were made using the tonometer. The relationship between Tono-Pen reading and manometer setting was linear over the full range of measurement. However, the slope of the data regression line deviated significantly from 1 and indicated that the instrument systematically underestimated IOP. For cats the average slope was 0.62 and for cows and sheep it was 0.72 and 0.69, respectively. For the latter animals, the regression line also had a nonzero intercept of approximately 4.5 mmHg. Similar results were obtained from in vivo and ex vivo eyes and with different Tono-Pen XL tonometers. Although developed for use on humans, the Tono-Pen XL can provide reproducible and accurate measurement of IOP in cats, cows and sheep when suitably calibrated by manometry. The calibration curves provided here, and by implication those reported for other animals using this tonometer, differ in slope from those measured with earlier models of the Tono-Pen. The reproducibility of the curves we obtained implies that they can be used to correct IOP readings from the Tono-Pen XL when manometry is not possible.

    On 1996, Tono Earth Science Center of JNC introduced the mass spectrometer tandem accelerator for isotope analysis of natural samples such as underground water and rocks. Facilities were 15SDH-2 pelletron type system made by NEC (Nihon Electric Company), Japan. Total beam generation times were 949 hours from April 1999 to January 2000. We made measurements on total 795 samples from November 1999 to April 2000 using the ion source for solid samples. Samples were IAEA calibration standards, oxalic acid of NIST (National Institute of Standards), CaCO{sub 3} from shells, BaCO{sub 3} and SrCO{sub 2} from underground water, CO{sub 2} from air, and organic samples from soils. Preliminary tests using the ion source for gaseous samples have been carried out. We have used NIST oxalic acid as a standard and an IAEA C1 sample as background. We have got the lower values in the case of IAEA C2, C3 and C7 samples. Accumulation of the data is needed to confirm accuracy. In addition, we are accepting samples from outside after September 1999. Major troubles are: breaks of pellet chain, sparks near terminals, and damages of rotating shaft. The troubles are already fixed. We are continuing operation to estimate accuracy in relation with careful initial treatment of samples. (Y. Tanaka)

    When designing investigations of microbial populations in the subsurface, it is extremely valuable to undertake scoping calculations to estimate the likely microbial abundances and evaluate the effects of contamination during sampling. A biogeochemical assessment of the groundwater and lithologies of the Tono mine, Japan, has been made using the BGS/NAGRA computer code BGSE (Bacterial Growth in Subsurface Environments). This code enables an assessment to be made of the maximum microbial growth rates that may be achieved in ideal circumstances, based on availability of nutrients and energy calculated from mineralogical and groundwater analyses. The effect of drilling fluid/groundwater mixing on biomass was assessed using a hypothetical drilling fluid composition. The results of modelling the mixing between groundwater and drilling fluid shows that the addition of only small concentrations of drilling fluid (<1% (v/v)) to the groundwater gives rise to significant microbial growth rates for the systems studied. Maximum growth rates were observed at ratios of 50:50 (v/v) (groundwater: drilling fluid) for the Akeyo and Toki lower groundwaters, and ratios of 90:10 (v/v) (groundwater:drilling fluid) for the Toki upper and Granite groundwaters. At low ratios of drilling fluid (<1% (v/v)) the limiting factor in each system was the availability of an energy source. This reflects the fact that the system is approaching pristine conditions. However, there was sufficient energy to permit a significant growth rate to be observed.

    The Tono uranium deposit, located in central Japan, is thought to have formed when oxidizing groundwater leached uranium from the underlying Toki Granite and transported it to the overlying host sedimentary formations where it precipitated under reducing conditions. Fission-track dating shows that this uranium mineralization took place ~10 million years ago and has remained immobilized despite episodes of sedimentation, uplift, subsidence, major faulting, and erosion. In order to understand the mineralogical controls on uranium immobilization, this study is gathering data on the mode of precipitation and adsorption of uranium within the various host lithologies. Optical petrography done on samples has shown a predominance of volcaniclastic deposits, containing glass shards within a fine-grained phyllosilicate matrix. Tephra that were formerly glass lack axiolitic devitrification textures and are altered to similar fine-grained mineralogy as in the matrix. X-ray diffraction data indicates that the majority of this fine-grained mineralogy is chlorite and the Mg, Ca smectite, saponite. Electron dispersive spectroscopy and back scattered electron data will create a map of the uranium concentrations and show any mineralogical affinities. Scanning and transmission electron microscope data will resolve the nature, crystallinity, and host sites of the uranium mineralization and help resolve the paragenesis in these tuffaceous rocks. This paper will address data gathered on samples across the host sedimentary formations and with depth to establish what mineralogical controls, if any, have influenced uranium precipitation and immobilization.

    To compare intraocular pressure (IOP) measurements by the Tono-Pen 2 tonometer and Goldmann applanation tonometer (GAT) in post-photorefractive keratectomy (PRK) patients. Refractive Surgery Center, Assaf Harofeh Medical Center, Zerifin, Israel. In 18 patients, IOP was measured by GAT and then by Tono-Pen 2 tonometer 2 to 18 months following PRK (mean 6.6 months +/- 5.1 [SD]). Photorefractive keratectomy had been performed in 1 eye of each patient; the fellow eyes served as controls. Corneal curvature and thickness were evaluated. Ten of the 18 patients were treated with topical steroids. In the post-PRK eyes, mean GAT IOP was 1.8 +/- 3.1 mm Hg lower than mean Tono-Pen IOP (P = .012); there was no significant IOP difference in the control (fellow) eyes. In steroid-treated post-PRK eyes, mean GAT IOP (12.2 mm Hg) was 2.2 +/- 1.3 mm Hg lower than mean Tono-Pen IOP (14.4 mm Hg) (P = .0007). Mean Tono-Pen IOP in steroid-treated post-PRK eyes was 4.3 +/- 3 mm Hg higher than in the fellow eyes (P = .0014); mean GAT IOP was only 2.3 +/- 3.5 mm Hg higher (P = .04). In post-PRK eyes without topical steroid treatment, mean GAT IOP was 2.0 +/- 1.18 mm Hg lower than in the fellow eyes (P = .001); there was no significant difference in Tono-Pen IOP. There was a negative correlation between the difference in IOP values (Tono-Pen minus GAT) and corneal curvature in post-PRK eyes (r = 0.76, P = .0108, n = 15). The Tono-Pen tonometer appeared to be less affected than the GAT by the relative flattening, thinning, and anterior stromal decreased rigidity of the central cornea that occur following PRK. Post-PRK steroid-induced IOP elevation may be masked by the artifactual decrease in GAT IOP.

    Measuring the intraocular pressure (IOP) on the sclera can be an alternative to conventional corneal measurement in eyes with scarred corneas. However, these measurements have to be evaluated prior in normal eyes. Our study aimed to evaluate scleral IOP using Tono-Pen and compared it with corneal Goldmann applanation measurements. The aim of this study was to evaluate the ability of limbal and scleral Tono-Pen IOP readings to predict central corneal Goldmann applanation tonometry (GAT) readings in eyes with normal corneas. In a cross-sectional study, 115 eyes of 115 patients attending a tertiary eye care center underwent GAT on the central cornea followed by Tono-Pen readings at the central cornea, at the limbus, and at the sclera. Bland-Altman plots were used to determine the agreement between different methods of IOP measurement. The median IOP (interquartile range) by GAT performed on the central cornea was 18 (16, 24) mmHg, and the IOP ranged from 10 to 54 mmHg. The median IOPs (interquartile range) by Tono-Pen obtained at central cornea, limbus, and sclera were 16 (13, 23), 23 (17, 28), and 33 (27, 44) mmHg, respectively. The Pearson correlation coefficient and the 95% limits of agreement between GAT readings and Tono-Pen readings at the central cornea were 0.9 (P < .001) and -4.9 to 8.74 mmHg, respectively. The correlation coefficient between GAT readings and Tono-Pen readings at the limbus and GAT readings and Tono-Pen readings at the sclera was 0.46 (P < .001) and 0.23 (P = .01), respectively. The 95% limits of agreement between these pairs of readings were -20.55 to 13.66 and -44.02 to 13.37 mmHg, respectively. This study showed limited ability of Tono-Pen readings obtained at the limbus and sclera to predict the central corneal GAT IOP readings in eyes with normal corneas at various IOP ranges.

    To assess the validity of central corneal thickness (CCT) and corrected intraocular pressure (IOP) values obtained by tono-pachymetry in non-surgical and post-photorefractive keratectomy (PRK) eyes. For the study, 108 young healthy participants and 108 patients who had PRK were enrolled. Measurements were randomly performed by tono-pachymetry, ultrasonic (US) pachymetry, and Goldmann applanation tonometry (GAT). CCT measurement by tono-pachymetry was compared to that of US pachymetry. The corrected IOP value obtained by tono-pachymetry was compared to that obtained by US pachymetry and GAT. The corrected IOP from US pachymetry and GAT was calculated using the identical compensation formula built into the tono-pachymetry. Bland-Altman plot and paired t -test were conducted to evaluate the between-method agreements. The mean CCT measurement using tono-pachymetry was significantly greater by 7.3 µm in non-surgical eyes ( p < 0.001) and 17.8 µm in post-PRK eyes ( p < 0.001) compared with US pachymetry. Differences were significant in both Bland-Altman plotand paired t -test. The mean difference of corrected IOP values obtained by tono-pachymetry and calculated from measurements by US pachymetry and GAT was 0.33 ± 0.87 mmHg in non-surgical eyes and 0.57 ± 1.08 mmHg in post-PRK eyes. The differences in the Bland-Altman plot were not significant. The CCT measurement determined using tono-pachymetrywas significantly thicker than that of US pachymetry. The difference in CCT was greater in post-PRK eyes than in non-surgical eyes. However, the corrected IOP value obtained by tono-pachymetry showed reasonable agreement with that calculated from US pachymetry and GAT measurements.

    To compare intraocular pressure (IOP) measurements taken with Pascal dynamic contour tonometry (DCT), the TonoPen and the Goldmann applanation tonometry (GAT). The influence of central corneal thickness (CCT) on IOP measurements taken with Pascal DCT and the TonoPen was evaluated. One eye in each of 101 consecutive patients with primary open-angle glaucoma (POAG) underwent ultrasonic CCT measurement and IOP evaluation with GAT, Pascal DCT and the TonoPen in random order. The agreement between results from Pascal DCT and the TonoPen and those of GAT was assessed using the Bland-Altman method. The deviation of Pascal DCT and TonoPen readings from GAT values, corrected for CCT, was calculated and correlated to CCT using a linear regression model. The mean of the differences in IOP measurements was 3.2 +/- 2.4 mmHg for Pascal DCT minus GAT readings and 0.5 +/- 4.5 mmHg for TonoPen minus GAT readings. The 95% confidence interval of differences in IOP measurements was higher between TonoPen and GAT readings (- 6 to 7 mmHg) than between Pascal and GAT readings (0.1-6.8 mmHg). Pascal DCT significantly overestimated IOP compared with GAT, especially for higher IOP readings. Bland-Altman scatterplots showed reasonable inter-method agreement between Pascal DCT and GAT measurements, and poor agreement between TonoPen and GAT measurements. The deviations of Pascal DCT and TonoPen readings from the corrected GAT values were both highly correlated with CCT values (linear regression analysis, p Pascal DCT and 0.74 mmHg for the TonoPen. Agreement with GAT measurements was higher for Pascal DCT than for TonoPen readings; however, Pascal DCT significantly overestimated IOP values compared with GAT. Measurements of IOP obtained with both Pascal DCT and the TonoPen appeared to be influenced by CCT, and this influence appeared to be greater for the latter.

    The purpose of this study was to evaluate the Tono-Pen 2 tonometer for measuring intraocular pressure (IOP) in the living rat eye. One eye from each of 20 adult, anesthetized brown Norway rats (group 1) was cannulated and simultaneously connected to a syringe and a pressure transducer with a chart recorder. We increased IOP from 15 to 45 mmHg in 5-mmHg increments and obtained 15 consecutive readings (ignoring instrument-generated averages) at each pressure increment with a Tono-Pen 2 tonometer. To test the tonopen's ability to measure unknown IOP, transducer pressures were varied randomly in 20 additional animals (group 2), and tonopen readings were obtained in masked fashion. Plotting the mean tonopen readings for each animal against transducer IOP produced a regression formula of y = 4.54 + 0.79x (r = 0.98). Mean group 2 tonopen values plotted against transducer IOP yielded a regression formula of y = 4.75 + 0.78x (r = 0.94). A method comparison analysis showed that the tonopen significantly overestimates pressures at low IOP ( or = 30 mmHg). Using two-way analysis of variance, it was determined that the group 2 data did not differ significantly from the group 1 data (P > or = 0.76). Because of this consistency, we generated a correction factor with 95% prediction intervals for Tono-Pen readings. The Tono-Pen 2 can be used reliably to measure IOP in the normal rat eye.

    When estimating intraocular pressure in patients who are uncooperative or who have central corneal disturbances, the physician may find it either impractical or undesirable to place the small tip of a portable electronic applanation tonometer (Tono-Pen) over the central cornea. To gauge better the usefulness of Tono-Pen readings obtained from various locations, we compared such readings measured through the central cornea, midperipheral cornea, limbal cornea, and sclera of 15 cannulated eye bank eyes. Mean Tono-Pen readings from the midperipheral and clear limbal cornea did not differ significantly from central corneal readings over a 10- to 35-mm Hg range of intraocular pressures and were within +/- 2.4 mm Hg of mean central corneal readings. Mean readings taken from the sclera, however, were 8.8 to 17.0 mm Hg higher than mean central corneal readings over the 10- to 40-mm Hg range. We concluded that multiple noncentral corneal readings with the Tono-Pen provided a useful approximation of intraocular pressure, whereas scleral readings did not.

    The Japan Nuclear Cycle Development Institute (JNC) has been conducting a wide range of geoscientific research in order to build a firm scientific and technological basis for the research and development of geological disposal. One of the major components of the ongoing geoscientific research programme is the Regional Hydrogeological Study (RHS) project in the Tono region, central Japan. The main goal of the RHS project is to develop and demonstrate surface-based investigation methodologies to characterize geological environments at a regional scale in Japan. The RHS project was initiated in 1992. To date, remote sensing, geological mapping, airborne and ground geophysical investigations, and measurements in nine deep boreholes have been carried out in the study area (ca. 100 km{sup 2}). Groundwater monitoring (water chemistry and pressure) is continuing in these boreholes. Important results that have been obtained from these investigations include multi-disciplinary information about the heterogeneity of lithological, hydrogeological, geochemical and rock mechanical properties of the granitic rock, and evolution of the groundwater geochemistry. During fiscal year 1999, two 1,000 m long cored boreholes (DH-10 and DH-11) were drilled. Core logging, geophysical logging, hydraulic testing and groundwater sampling were conducted in these boreholes. Laboratory tests provided information about physical, rock mechanical and geochemical properties of granite in deep sections of these boreholes. Groundwater monitoring was continued in the existing boreholes. The usefulness and applicability of airborne and ground geophysical investigation methods were evaluated. Geological and hydrogeological models were developed based on information obtained until 1999. Groundwater flow simulation was conducted in order to evaluate the influence of boundary conditions and properties assigned to each hydrogeological unit.

    The current geosientific studies in the Tono Mine have been carried out since 1998. The main aims of the studies are to assess solute transport/retardation in Tertiary sedimentary rocks that host uranium ore bodies and to develop comprehensive techniques for the characterisation of faults, near-field geological environments around tunnels, etc in the sedimentary formation. A variety of results were obtained in the 2001 financial year in four different tasks involved in the studies. The long-term time-dependent behaviour of the rock mass was characterised by a couple of experimental studies involving in situ rock mass displacement measurements for over a decade and laboratory creep tests on sedimentary rock samples. In addition, temperature-dependent rock creep behaviour and a stress relaxation process were described. In the tunnel near-field geological environments, 3D distribution of pore water pressure and penetration of oxidised zone into the sedimentary formation were characterised. For the in situ characterisation of an unsaturated zone surrounding the tunnel, the applicability of a packer-type TDR (Time Domain Reflectometry) probe developed was confirmed. As part of studies on solute transport/retardation in the rock mass, the stability of reducing environment and uranium geochemistry in the host sedimentary formation were evaluated based upon the hydrogeochemical data sets developed in this task. Information on microbial diversity and abundance in groundwater and activity of sulphate-reducer was obtained. With respect to the Tsukiyoshi fault observed in the sedimentary formation, all information obtained were synthesised and a spatial distribution, geometrical features, the past movement and its function for groundwater flow were described in detail. Limitations and future approaches to the dating of a fault activity were discussed in this study. (author)

    To experimentally examine the effect of corneal modulus on Goldmann applanation tonometry (GAT) and Tono-pen (Tono-pen XL, Reichert, Inc., Depew, NY) measurements of intraocular pressure (IOP) in a canine eye model. Twenty-one canine globes were recovered from healthy animals. IOP was controlled at 10, 15, 20, 30, and 40 mm Hg and measured by GAT and Tono-pen following standard protocols. The corneas were dissected and uniaxial tensile tests were performed on corneal strips. The correlation between GAT and Tono-pen errors and corneal secant modulus was evaluated using Pearson correlation coefficients. The influence of corneal thickness and the true pressure was also examined. At a true IOP of 10, 15, 20, 30, and 40 mm Hg, the GAT readings were 1.1 ± 1.0, 5.1 ± 1.5, 9.5 ± 2.0, 17.3 ± 1.6, and 25.3 ± 1.8 mm Hg, respectively. The corresponding Tono-pen readings were 7.8 ± 1.7, 12.4 ± 1.7, 16.1 ± 1.9, 22.5 ± 2.1, and 28.1 ± 2.2 mm Hg, respectively. The mean secant modulus at 1% strain of the canine corneal strips was 1.54 ± 0.43 megapascal (MPa). Corneal secant modulus was significantly correlated with GAT errors when the true IOP was 30 mm Hg (R = 0.49; P < 0.05). No significant correlation was observed between tonometric errors and corneal thickness. Both GAT and Tono-pen errors increased significantly at higher pressures (P < 0.001). Both GAT and Tono-pen underestimated IOP in canine eyes. There was preliminary experimental evidence for a correlation between corneal modulus and GAT in the canine eyes and a higher corneal modulus was associated with higher GAT readings at a certain pressure level. The tonometric errors appeared to be pressure-dependent.

    Mononuclear cells from the peripheral blood of patients with systemic lupus erythematosus (SLE) were transformed with the Epstein-Barr virus (EBV) and the resultant polyclonal B-lymphoblastoid cell lines were tested for antibody activity to membrane antigens of certain T-cell lines. B lymphoblastoid cell lines secreting specific antibodies were fused with (mouse x human) heteromyeloma SHM-D33 cells. Among the large number of hybridomas generated, one which produced a human monoclonal antibody (MAb) TONO-1 (IgM, lambda) was selected. MAb TONO-1 proved to be reactive with 4 human T-cell lines, HPB-MLT, L-MAT, MOLT-3 and MOLT-4F, but not with B-leukemia, Burkitt's lymphoma, myelomonocytic leukemia, erythroleukemia or non-hematopoietic malignant cell lines. MAb TONO-1 reacted positively with fresh leukemia cells from 2 of 7 patients with acute T-lymphocytic leukemia, but no reaction was observed in non-T-cell leukemia cases. Normal lymphocytes, monocytes, granulocytes, red blood cells and platelets in the peripheral blood did not demonstrate remarkable binding. Neither thymocytes nor bone-marrow cells from healthy volunteers were reactive. The antigens defined by MAb TONO-1 were polypeptides of 57 kDa and 68 kDa. Immunohistological studies revealed no staining of thymocytes in the thymus of a 6-month-old child, but showed epithelial reticular cells and Hassall's corpuscles to stain positively. These results suggest that MAb TONO-1 is directed to T-leukemic cells and some components of thymus tissue.

    To evaluate the agreement of Goldmann applanation tonometer (GAT) with Tono-Pen and noncontact tonometer (NCT) for measurement of intraocular pressure (IOP) in pediatric age group and to evaluate the correlation between central corneal thickness (CCT) and IOP measured with the tonometers used. IOP was measured in 200 eyes in a group of Indian children, aged between 8 and 18 years using three different tonometers: NCT, the Tono-Pen and GAT. All IOP readings were made in the office settings by the same examiner. Readings obtained were compared between the instruments and with the CCT for each tonometer. Tonometer inter-method agreement was assessed by the Bland-Altmann method. The relations of CCT with absolute IOP values and inter-tonometer differences were analyzed by linear regression. The mean age was 13.37 ΁ 3.51 years. The mean IOP values recorded with NCT; Tono-Pen and GAT were 14.38, 15.63, and 12.44 mmHg, respectively. Both Tono-Pen and NCT recorded statistically higher IOP values than the GAT (P = 0.00) regardless of the CCT. The percentage increase of IOP measured over GAT was 15.66% for NCT and 25.70% for Tono-Pen which was also statistically significant. A correlation was found between CCT and IOP values obtained with all the three tonometers. IOP measurements on children vary significantly between instruments and correlations are affected by the corneal thickness. Further studies on children are needed to determine which instrument is most appropriate and to derive a normative IOP scale for the growing eye.

    A clinical evaluation of a new electron ProTon tonometer was performed comparing the values of intraocular pressure (IOP) measured using this instrument with those determined by a similar instrument, Tono-Pen XL, and by Goldmann applanation tonometry. The mean IOP measured in 106 eyes with the ProTon tonometer was not significantly different from that determined with Goldmann applanation, while the IOP values measured with Tono-Pen XL were significantly lower. The 95% limits of agreement between applanation tonometry and ProTon tonometry were between -4 mm Hg and 5 mm Hg and between applanation tonometry and Tono-Pen XL tonometry between -3 mm Hg and 8 mm Hg. The ProTon tonometer appears to have a higher level of accuracy than the Tono-Pen XL tonometer in clinical practice.

    To explore the effect of body position (sitting vs supine) on intraocular pressure (IOP) in children, as assessed by the Icare PRO and the Tono-Pen. Prospective clinical study. Children with known or suspected glaucoma and those without glaucoma were recruited from the Duke Eye Center pediatric clinic. Subjects underwent tonometry in both eyes while upright (sitting), after instillation of topical anesthetic, with either the Icare PRO or the Tono-Pen first, and then the second instrument (order randomized). Goldmann applanation tonometry (GAT) was then performed by a clinician masked to the previous measurements. The subjects were then placed in the supine position for 5 minutes, and tonometry using the Icare PRO and the Tono-Pen was obtained, in the same order used when they were the sitting position. Enrolled were 47 children (94 eyes). Mean seated IOP for GAT, Icare PRO and Tono-Pen were 16.4 ± 4.2, 17.5 ± 3.5, and 18.0 ± 3.9 mm Hg, respectively. The mean supine IOP for the Icare PRO and Tono-Pen were 18.4 ± 4.5 and 18.8 ± 4.2 mm Hg, respectively. This rise was +0.9 ± 2.3 mm Hg for Icare PRO (P = 0.01) and +0.7 ± 1.8 mm Hg for Tono-Pen (P = 0.009), respectively. In children, Icare PRO tonometry correlates well with GAT in the sitting position, and with the Tono-Pen in both the sitting and supine positions. IOP rises when a child changes position from sitting to supine when measured by the Icare PRO or the Tono-Pen. However, the increase, which is less than 1 mm Hg, seems clinically insignificant and is unlikely to alter glaucoma management in children. Copyright © 2014 Elsevier Inc. All rights reserved.

    In clinical practice ophthalmologists often need a tonometer which is independent of a slit lamp. Such a hand-held device is the Tono-Pen. We compared the precision of two equal Tono-Pens with Goldmann applanation tonometry. Measurement of intraocular pressure (IOP) was done in 100 eyes of 51 patients (mean age 63 +/- 15 years) suffering from ocular hypertension or glaucoma. According to a random table either the right or left eye was measured using Goldmann tonometer first and the Tono-Pen second. For the other eye the measurement was reversed. One of the two equal Tono-Pens (Solan/USA) was used according to a second random table. Three measurements were obtained with each instrument on both eyes within 15 minutes subsequently. Patients were placed in an upright position for all measurements. Even for well-trained ophthalmologists a learning curve of approximately 10 measurements was observed using the Tono-Pen. The Tono-Pen measured an average IOP of 16.9 mm Hg in all 100 eyes. The Goldmann tonometer measured an average IOP of 17.7 mm Hg. The difference was not statistically significant. The standard deviation for all measurements was better for the Tono-Pen (4.7 mm Hg vs 5.8 mm Hg for Goldmann tonometer). No reduction of the IOP after Tono-Pen measurement was observed (in contrast to the Goldmann tonometer). The reproducibility of the Tono-Pen on the same eye was inferior to the Goldmann tonometer by a factor of 2. There was an almost significant difference in reproducibility between two equal Tono-Pens. Measurement of IOP with the Tono-Pen is comparable to Goldmann applanation tonometry if an average of 3 measurements is used. The difference between two equal Tono-Pens indicates the need for improvement of the quality check during production.

    To assess the agreement of intraocular pressure (IOP) measured with the Tono-Pen and the Goldmann applanation tonometer (GAT) in normal children and adolescents. A total of 439 subjects from birth to 11 mm Hg in the office setting. Using the average of GAT and Tono-Pen IOPs to estimate the true IOP, the average difference (GAT - Tono-Pen) was 0.4 mm Hg at IOP of 10 mm Hg and -3.0 mm Hg at IOP of 20 mm Hg. The 95% limits of agreement on the average difference between instruments were ± 6.4 mm Hg in the office setting and ± 6.8 mm Hg under general anesthesia. Larger differences between instruments were found with younger age. Standard error of measurement with the Tono-Pen was 1.44 mm Hg and 1.82 mm Hg for the office and anesthesia settings, respectively. Thicker corneas were associated with higher IOP with both the GAT and the Tono-Pen. In normal children, average differences between IOP measured by Tono-Pen and GAT were small, although there was substantial test-retest variability. Younger age was associated with larger average differences, as was higher IOP in the office setting. Copyright © 2012 American Association for Pediatric Ophthalmology and Strabismus.

    The Tono-Pen XL (Bio-Rad, Santa Ana, CA) was compared with manometer readings for intraoperative measurement of intraocular pressure (IOP) in 40 eyes of 40 consecutive patients after vitrectomy, lensectomy, and fluid-air exchange. Tono-Pen readings corresponding to manometer readings of 10, 20, 30, 40, and 50 mmHg were obtained in a masked fashion with a randomized sequence of manometer readings. A correlation was obtained between the manometer and Tono-Pen readings (r = 0.96 in emmetropic eyes and r = 0.93 in myopic eyes). The regression curve that represents the calibration curve of Tono-Pen in terms of the manometer readings for air-filled vitrectomized eyes was obtained. Any Tono-Pen reading can be easily translated into the corresponding manometer reading by referring to the curve. The Tono-Pen can therefore be effectively used to accurately determine intraoperative IOP in eyes undergoing vitrectomy, lensectomy, and fluid-air exchange.

To date, remote sensing, geological mapping, airborne and ground geophysical investigations, and measurements in eleven deep boreholes have been carried out in the study area (c. 100 km{sup 2}). Groundwater monitoring (water chemistry and hydraulic head) is continuing in these boreholes. Important results that have been obtained from these investigations include multi-disciplinary information about the heterogeneity of lithological, hydrogeological, geochemical and rock mechanical properties of the granitic rock, and evolution of the groundwater geochemistry. During fiscal year 2000, two 1,000 m long cored boreholes (DH-12 and DH-13) were drilled. Core logging, geophysical logging, hydraulic testing and groundwater sampling were conducted in these boreholes. Laboratory tests were performed to provide information about physical, rock mechanical and geochemical properties of granite in deep sections of these boreholes. Groundwater monitoring was continued in the existing boreholes. The usefulness and applicability of ground geophysical investigation methods were evaluated. As part of evaluation of data uncertainties for modeling and simulation, geological and hydrogeological models were developed based on information obtained in an initial investigation stage. Groundwater flow simulation was conducted in order to estimate the extent of groundwater flow system in the study

    This is a descriptive study designed to assess the predictive value of intraocular pressure (IOP) measurement in GPs' offices in an urban healthcare site using Tono-pen XL. A total of 2044 patients, aged > or =40 years, were enrolled by consecutive sampling from patients visiting the GP. Those participants who had IOP > or =21 mmHg were referred to the ophthalmologist. Of the 226 then tested, ocular hypertension was confirmed in 100 participants (4.89%, 95% CI [confidence interval] = 3.93 to 5.85%). Predictive value was 44.2%. These results suggest the validity of using Tono-pen XL in the GP's office to detect ocular hypertension.

    To examine the relationship between intraocular pressure (IOP) readings taken by the Tono-Pen tonometer (Mentor O&O, Norwell, MA) and central corneal thickness (CCT). Prospective cross-sectional population study. There were 651 eyes of 332 healthy subjects. A questionnaire was given to each subject requesting information on gender, age, race, and other factors that can influence IOP. The IOP then was measured using the Tono-Pen followed by measurements of CCT using an ultrasonic pachymeter. The IOP was found to increase by 2.9 mmHg/100 microns CCT in males and 1.2 mmHg/100 microns in females. For males, CCT was found to be statistically significant in predicting IOP (P < 0.001 in the right and left eyes) and diabetes was of borderline significance (P = 0.012 in the right eye, P = 0.089 in the left eye). For females, CCT was of borderline significance (P = 0.064 in the right eye, P = 0.019 in the left eye). In females, a family history of glaucoma (P = 0.021 in the right eye, P = 0.022 in the left eye) and hypertension (P = 0.010 in the right eye, P = < 0.001 in the left eye) were also significant in the prediction of IOP. Race was found to be a significant predictor of CCT (P < 0.001 in both right and left eyes) for both males and females. Clinicians should be aware that, as with the Goldmann applanation tonometer, the Tono-Pen has a systematic error in IOP readings caused by its dependence on CCT. Tono-Pen IOP readings are positively correlated to CCT in males and, to a lesser extent, in females as well. The CCT measurements should be considered to ensure proper interpretation of IOP measurements in the diagnosis and management of disorders in which the CCT or IOP readings are outside normal limits.

    To determine the reliability of Tono-Pen XL in measuring intraocular pressure (IOP) over the amniotic membrane patch in human eyes. Ten healthy volunteers (nine males and one female) participated in this study. After topical anesthesia, IOP was measured using the Tono-Pen XL before and after the application of a single-layer amniotic membrane patch in the right eye and double-layer amniotic membrane patch in the left eye. We found no statistical difference between the IOP measured with and without a single layer amniotic membrane (P = 0.808). Nor did we find any statistical difference between the IOP measured with and without double-layer amniotic membrane patch (P = 0.813). The average thickness of the single- and the double-layer amniotic membrane patch measured by pachymetry was 131.9 +/- 31.4 microm (mean +/- SD) and was 246.1 +/- 69.3 microm (mean +/- SD), respectively. This study showed that it is reliable to measure IOP by Tono-Pen XL over single or a double layer of amniotic membrane patch on healthy human eyes. Further studies are required to determine the accuracy of IOP measurement over amniotic membrane patch on diseased corneas.

    Tono-pen measurement of intraocular pressure (IOP) under topical anaesthesia in full term normal newborns. The IOP measurements were taken using Tono-pen XL tonometer under topical anaesthesia in 150 newborns (300 eyes) within 24h after birth, over a period of three months, in a university hospital. Gender, gestation period, mode of delivery and birth weight of newborns were noted from medical records. There were 70 males and 80 females. All babies were Malays. The IOP measurements were taken between 12 and 24h after birth. The gestation period of babies ranged between 37 and 41 weeks; 118 babies were delivered by spontaneous vaginal delivery and 32 by caesarian section. The birth weight of babies ranged between 2.1 and 4.3kg. The mean IOP of 300 eyes was 15.99±2.79mmHg (range 8-22). There was no statistically significant difference of mean IOP and gender, laterality of eye, type of delivery, gestation age, or birth weight of newborns. The IOP in full term normal newborns was 16mmHg. Tono-Pen appears to be ideal instrument for taking IOP in newborns because of its small size and easy handling.

    1998-12-01

    To study if the Tono-Pen, a hand held digital tonometer, can replace Schiøtz tonometry in general practice. Tonometry with Tono-Pen and Schiøtz tonometer were compared. Group practice with two general practitioners (GPs). 48 consecutive patients over 40 years of age. The mean difference between intra ocular pressure (IOP) measured with the two methods with 95% confidence intervals and 95% limits of agreement between them. One observer found a mean difference between methods of 0.3 mmHg and 95% limits of agreement of +/- 4 mmHg. The other observer with a different Schiøtz tonometer, had a mean difference of approximately -2 mmHg and 95% limits of agreement from -8 to +4 mmHg. We consider the Tono-Pen to be an alternative to Schiøtz tonometry. The maximum mean difference between the methods for one GP, 1.9 mmHg, was within clinically acceptable limits. Possible reasons for the different agreement for the two observers are discussed.

    To compare the accuracy of Goldmann tonometry with that of the Tono-Pen(R) in measuring intraocular pressure (IOP) after photorefractive keratectomy (PRK). Eye Clinic, Cantonal Hospital, Lucerne, Switzerland.Thirty-five eyes (25 patients) had PRK for a mean myopia of -6.2 diopters +/- 2.6 (SD). Intraocular pressure (IOP) measurements were performed first with the Goldmann tonometer and then with the Tono-Pen in 2 corneal locations: centrally in the usual manner and temporally. For the temporal measurements, the patient was directed to gaze nasally as the tonometer was placed perpendicular to the temporal portion of the cornea and with the rim of the tonometer positioned just inside the limbus of the cornea. Subsequently, similar measurements were made with the Tono-Pen. Measurements were performed before and 1 and 3 months after PRK. Preoperative IOPs measured centrally and temporally were similar. After PRK, the central pressure readings with the Goldmann tonometer and the Tono-Pen were between 1.8 and 2.3 mm Hg lower than those measured temporally. The differences were statistically significant (P <.0001). Central corneal pressure readings obtained with either the Goldmann tonometer or the Tono-Pen after myopic PRK are inaccurate. Measurements over the temporal part of the cornea are likely more reliable.

    2008-01-01

    This cross-sectional study aimed to investigate if the Tono-Pen, Schiøtz and Perkins tonometers could be used interchangeably in general practice for measuring elevated intraocular pressure. A total of 74 eyes of 37 paediatric patients under general anaesthesia were checked with all 3 tonometers. All of the tonometers gave significantly different measurements from each other. However, with a mean difference of 1.4 mmHg and 95% limits of agreement of -5.7 to +8.6, the greatest agreement was between the Perkins and Tono-Pen tonometers. The Perkins tonometer is a hand-held variant of the Goldmann tonometer (the gold standard for intraocular pressure measures). Therefore the Tono-Pen with its ease of use and safety could be a reliable device for use in general practice.

    The purpose of this study was to assess the interoccasion repeatability of the Tono-Pen XL portable applanation tonometer in school-aged children. Thirty-one normal children were recruited from The Ohio State College of Optometry Pediatric Clinic. They ranged in age from 6 to 14 years. Intraocular pressure was measured using the Tono-Pen XL in both eyes of all subjects on two different occasions within a median of 9 days. Refractive error was measured by noncycloplegic autorefraction. Data from right eyes only are presented. There was no average difference in the intraocular pressure between occasions. The 95% limits of agreement between occasions were -5.58 to 4.87 mm Hg. The Tono-Pen XL gives reasonably repeatable readings between occasions in school-aged children.

    We performed 84 intraocular pressure measurements with the Oculab Tono-Pen, Goldmann applanation tonometer, and pneumatic tonometer in 47 eyes that had undergone pars plana vitrectomy and gas-fluid exchange. Measurements made by using the Tono-Pen were accurate when compared to those made by Goldmann tonometry (mean difference, 0.74 mm Hg). In a subset of eyes with increased intraocular pressure (greater than or equal to 25 mm Hg), the Tono-Pen provided measurements similar to those made by Goldmann applanation tonometry (P greater than .60), with only three of 39 readings (8%) underestimating the Goldmann pressure by more than 3 mm Hg. Pneumatic tonometry significantly underestimated the intraocular pressure in eyes with increased pressure (P less than .001), with 20 of 39 readings (51%) underestimating the Goldmann pressure by 5 mm Hg or more.

    To evaluate the influence of amniotic membrane on intraocular pressure (IOP) measurement with the Tono-Pen. Observational case series. Eight patients with partial limbal dysfunction who underwent penetrating keratoplasty were recruited. Amniotic membranes were patched just after keratoplasty. One week postoperatively, amniotic membranes were removed, and accuracy of IOP measurement with the Tono-Pen was evaluated with comparisons before and after the removal. No epithelial defects were detected after the removal of amniotic membrane. Mean IOPs with and without amniotic membranes were 16.6 +/- 3.0 mm Hg (mean +/- SD) and 16.0 +/- 3.7 mm Hg, respectively. The difference was not statistically significant. Assessment of IOP with the Tono-Pen was observed to be accurate even when used over an amniotic membranes patch in cases who underwent penetrating keratoplasty.

    Intraocular pressure in 21 eyes filled with silicone oil was measured with two different instruments: the Oculab Tono-Pen and a Goldmann applanation tonometer mounted to a slit lamp biomicroscope. Intraocular pressure ranged from 2 mmHg to 28 mmHg, and the mean difference between readings obtained from the two instruments was 0.64, which was not statistically significant. These results suggest that the Oculab Tono-Pen is an effective instrument with which to measure intraocular pressure in silicone-filled eye.

    The Tertiary Tono sandstone-type uranium deposit is recognized as a potentially useful analogue for the geological isolation of radioactive wastes in Japan. The study of this natural analogue is being carried out to acquire information about the geochemical processes that relate to the containment and migration of uranium series nuclides over geologic time. There is no significant migration for uranium for the samples investigated as the result of radioactive disequilibrium study. The hydrogeochemical study suggests that the groundwater in the ore horizons is very stagnant and reducing

    To compare intraocular pressure (IOP) measurements of the Ocular Blood Flow (OBF) pneumotonometer, Goldmann applanation tonometer, and Tono-Pen in eyes with normal corneas of various thicknesses. IOP was measured with an OBF pneumotonometer, Tono-Pen and Goldmann applanation tonometer in random order in 181 eyes with normal corneas. Central corneal thickness (CCT) was measured using an ultrasonic pachymeter after all IOP determinations had been made. Right and left eyes were analyzed separately for statistical purposes. With all instruments, IOP varied with CCT, even though the variation in IOP was large. Readings with the OBF pneumotonometer showed a mean increase in IOP with increasing CCT of 0.28 mm Hg/10 microm, an increase of 0.23 mm Hg/10 microm with the Goldmann tonometer, and of 0.10 mm Hg/10 microm with the Tono-Pen. The OBF pneumotonometer consistently recorded comparatively higher IOPs than the other two instruments. The Tono-Pen is least affected by CCT when used to measure IOP in eyes with normal corneas. The OBF pneumotonometer appears to be more affected by variation in CCT than the Goldmann tonometer. This is contrary to expectations, based on the mechanism of measurement of IOP of the OBF pneumotonometer.

The AMS system is versatile, based on a 5 MV tandem Pelletron-type accelerator. Since its establishment in 1997, the AMS system has been used for measurement of carbon-14 (14C) mainly for 14C dating studies in neotectonics and hydrogeology, in support of JAEA's research on geosphere stability applicable to the long-term isolation of high-level radioactive waste. Results of the measurement of 14C in soils and plants has been applied to the dating of fault activity and volcanism. Development of beryllium-10 (10Be) and aluminum-26 (26Al) AMS systems are now underway to enhance the capability of the multi-nuclide AMS in studies of dating by cosmogenic nuclides. The 10Be-AMS system has already been used for routine measurements in applied studies and improvements of the measurement technique have been made. Now we plan to fine tune the system and perform test measurements to develop the 26Al-AMS system.

    To determine the effect of central corneal thickness and radius of the corneal curvature on intraocular pressure (IOP) measurements using the Tono-Pen and a noncontact tonometer in healthy Turkish schoolchildren. IOP was measured with the Tono-Pen and a noncontact tonometer in 602 eyes of 602 healthy schoolchildren with a mean age of 10.1 +/- 1.6 years. Central corneal thickness was measured using an ultrasonic pachymeter after all IOP determinations had been made. The effect of central corneal thickness, radius of the corneal curvature, and sex on measured IOP was explored by linear regression analysis. The mean central corneal thickness was found to be 564.92 +/- 32 microm. The mean IOP readings were 17.9 +/- 2 mm Hg using the Tono-Pen, and 16.7 +/- 2 mm Hg using a noncontact tonometer. The Tono-Pen measured IOP values slightly greater than the noncontact tonometer (P < .0001). A significant association between measured IOP and central corneal thickness was found with each device. The IOP increased 2.1 and 4.2 mm Hg with every 100-microm increase in central corneal thickness for the Tono-Pen and the noncontact tonometer, respectively. The dependence of IOP on central corneal thickness did not differ between boys and girls. There was a significant association between the Tono-Pen and noncontact tonometer differences and central corneal thickness; the noncontact tonometer tended to overestimate IOP in eyes with thicker corneas. The Tono-Pen readings appeared to be less affected by corneal thickness than those of the noncontact tonometer. The corneal radius of curvature had no significant effect on measured IOP with each device. Because the Tono-Pen was relatively easy to use and less affected by corneal thickness, it may be an alternative method for measuring IOP in children.

    The Japan Nuclear Cycle Development Institute (JNC) has been conducting a wide range of geoscientific research in order to build a firm scientific and technological basis for the R and D of geological disposal. One of the major components of the ongoing geoscientific research program is the Regional Hydrogeological Study (RHS) project in the Tono region, central Japan. The main goal of the RHS project is to develop and demonstrate surface-based investigation methodologies to characterize geological environments on a regional scale in Japan. The RHS project was initiated in 1992. To date, remote sensing, geological mapping, geophysical investigations and measurements in thirteen deep boreholes have been carried out. Important results that have been obtained from these investigations include multi-disciplinary information about the geological, hydrogeological, geochemical and rock mechanical properties of granitic rock, and evaluation of the groundwater geochemistry. The JNC will synthesize the results from the R and D activities in fiscal 2004. (author)

  10. Solubility constraints on uranium concentrations in groundwaters of the tono uranium deposit, Japan

    A key concept underpinning most safety assessments of geological disposal systems for high-level nuclear wastes is that the maximum aqueous concentrations of actinide elements released from the waste will be limited by the solubility of the corresponding tetravalent oxide or hydrous oxide. The validity of this concept for U is evaluated in the present study using hydrochemical and mineralogical data from the tono uranium (U) deposit in gifu prefecture, Japan. In addition, the long-term stability of U mineralization in the tono deposit is assessed in terms of plausible range of U solubilities in paleogroundwaters migrating through the deposit. A thermodynamic evaluation of the aqueous-speciation and solubility behaviour of U indicates that U concentrations in the coexisting groundwaters greatly exceed the solubility of both uraninite [UO{sub 2}(c)] and coffinite [USiO{sub 4}(c)]. The dissolved U concentrations appear instead to be controlled by the solubility of amorphous hydrous U(IV) oxide [UO{sub 2}(am)], which is metastable with respect to uraninite. Mineralogical and microbiological investigations suggest that pH-E{sub h} conditions similar to those observed presently in groundwaters of the lower toki lignite-bearing formation (pH {approx} 8-10; E{sub h} {approx} -250--410 mV) have been buffered, possibly since the present geological structure formed about 5-0.7 Ma, by microbial sulphate reduction and precipitation/dissolution of calcite. If so, corresponding U concentrations controlled by UO{sub 2}(am) solubility are calculated to have been in the range of 10{sup -6.1} and 10{sup -8.7} mol kg{sup -1} depending on the possible environmental conditions, i.e., E{sub h}, pH and carbonate concentration.

    Based on geochemical data collected by Japan Nuclear Cycle Development Institute (JNC) in the Tono uranium mine, a conceptual groundwater evolution model developed by JNC is tested to evaluate whether equilibrium-based concepts of water-rock interaction are consistent with observed variations in the mineralogy and hydrochemistry of the Tono mine area. 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 that it is possible to interpret approximately the actual groundwater chemistry (i.e., pH, Eh, total dissolved concentrations of Si, Na, Ca, K, Al, carbonate and sulfate) if the following assumptions are adopted (a) CO 2 concentration in the gas phase contacting pore solutions in the overlying soil zone=10 -1 atm, and (b) 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). This result helps to build confidence in the use of simplified geochemical modeling techniques to develop an understanding of dominant geochemical reactions controlling groundwater chemistry in rocks similar to those that could be used for the geological disposal of radioactive wastes. 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 are needed to improve the model. 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 improvement of model considering ion-exchange reactions are needed in future, however.

    To assess the effect of examiner handedness on intraocular pressure (IOP) readings using the Tono-Pen XL in eyes without corneal pathology or previous ocular surgeries. Patients 18 years of age or older were included in this prospective study. Participants who had a history of corneal conditions or other characteristics that would prevent reliable IOP measurements were excluded. Five experienced examiners, 2 right-hand dominant and 3 left-hand dominant, took bilateral IOP measurements with a Tono-Pen XL. Each participant was tested by 2 examiners, 1 left-handed and 1 right-handed, in a random order. The time between each examiner's measurements was 15 minutes. A paired t test was used to compare IOP differences between "near" (right eye for right-hand or left eye for left-hand dominant examiner) and "far" (right eye by left-hand or left eye by right-hand dominant examiner) measurements for each eye. Forty-six participants with a mean age of 33.8 years (±12.8) were enrolled. No significant difference in IOP between near and far eyes was found (IOP difference=IOPfar-IOPnear=-0.11 [±2.74] mm Hg; P=0.70). Right-hand dominant examiners consistently measured significantly higher IOP (0.83±2.03 mm Hg; P=0.008) compared with left-hand dominant examiners, regardless of the relative position of the eye with respect to the examiner. The results suggest that IOP readings are not influenced by the positioning of the patient relative to the dominant hand of the examiner.

    To evaluate the influence of central corneal thickness (CCT) on intraocular pressure (IOP) measurements made with the Goldmann applanation tonometer (GAT), Tono-Pen XL, ocular blood flow tonograph (OBF), and Canon TX-10 non-contact tonometer (NCT). CCT was recorded for either eye (randomly selected) of each of 105 untreated patients with ocular hypertension and glaucoma attending the glaucoma research unit at Moorfields Eye Hospital. For each of the selected eyes, IOP was measured with the GAT (two observers), Tono-Pen, OBF, and NCT in a randomised order. The relation of measured IOP and of inter-tonometer differences with CCT and subject age was explored by linear regression analysis. A significant association between measured IOP and CCT was found with each instrument. The change in measured IOP for a 10 mum increase in CCT was 0.28, 0.31, 0.38, and 0.46 for the GAT, Tono-Pen, OBF, and NCT, respectively (all p< or = 0.05). There was a significant association between the NCT/GAT differences and CCT, with a tendency of NCT to overestimate GAT in eyes with thicker corneas. There was a significant association between GAT/Tono-Pen and OBF/Tono-Pen differences and age, with a tendency of GAT and OBF to overestimate the Tono-Pen in eyes of older subjects. IOP measurement by all four methods is affected by CCT. The NCT is affected by CCT significantly more than the GAT. Subject age has a differential effect on the IOP measurements made by the GAT and OBF compared to the Tono-Pen.

    To compare intraocular pressure (IOP) measurements obtained using the Icare Pro rebound tonometer and Tono-Pen XL tonometer in supine and lateral decubitus body positions. One-hundred eyes of 50 subjects (normal volunteers or glaucoma suspects) were enrolled in this prospective observational study. IOP was measured in both eyes using the Icare Pro and Tono-Pen XL in the sitting position and the recumbent positions including supine, right lateral decubitus and left lateral decubitus. IOP was measured five minutes after assuming each of the recumbent postures in a randomized sequence. The eye on the lower side in the lateral decubitus position was termed as the dependent eye. Agreement of IOP readings between the Icare Pro and Tono-Pen was assessed in all recumbent positions. Differences of IOP readings (ΔIOP) between the two tonometers and their correlations with ocular parameters were also assessed in all positions. The IOP readings obtained using Icare Pro and Tono-Pen showed good correlations in supine and lateral decubitus positions (all r > 0.7, p < 0.005), although Icare Pro readings were higher than Tono-Pen readings (all p < 0.001) in all positions. The ΔIOP showed a weakly positive correlation with central corneal thickness in both eyes, whereas such a positive correlation was found only in the dependent eye in the lateral decubitus positions (r = 0.307-0.531, all p < 0.005). Both the spherical equivalents and axial lengths were not correlated with ΔIOP in all positions. IOP readings obtained with Tono-Pen and Icare Pro tonometers showed good agreement in supine as well as in lateral decubitus positions, although Icare readings were higher than Tono-Pen readings in all positions. Such differences in IOP readings between the different tonometers need to be considered when measuring IOPs in various body positions.

There was a significant association between the NCT/GAT differences and CCT, with a tendency of NCT to overestimate GAT in eyes with thicker corneas. There was a significant association between GAT/Tono-Pen and OBF/Tono-Pen differences and age, with a tendency of GAT and OBF to overestimate the Tono-Pen in eyes of older subjects. Conclusion: IOP measurement by all four methods is affected by CCT. The NCT is affected by CCT significantly more than the GAT. Subject age has a differential effect on the IOP measurements made by the GAT and OBF compared to the Tono-Pen. PMID:15965165

    The Tono Geoscience Center of the Japan Nuclear Cycle Development Institute (JNC) has progressed various types of survey and research targeted at new Tertiary sedimentary rocks and bed rock granite distributing from earth surface to about 500 m in depth at and around the Tono mine belonged to Toki-city of Gifu prefecture, as a part of the stratum science research. The survey and research are carried out to aim at understanding on material transfer and delay feature of uranium in the sedimentary rocks with geological characteristics such as dislocation according to the 'Basic plan on survey and testing research at the Tono mine', and their items are survey and testing researches on 1) dynamic stability of rocks, 2) geological environment around road, 3) material transfer in rocks, and 4) the Tsukiyoshi fault. Results obtained in the survey and testing research not only are reflected as a base of the stratum disposal R and D, but also contribute to academic research on deep underground, application of underground space, and so on. For example, a research on sampling and applying of rocks containing uranium helps elucidation on formation of uranium ore deposit and forming process. (G.K.)

    The accuracy of intraocular pressure measurement with the minified Goldmann applanation tonometer, the pneumatonometer, and the Tono-Pen tonometer were compared in post-mortem human eyes which had undergone penetrating keratoplasty. Enucleated post-mortem human eyes underwent same sized (7.75 mm) or 0.5 mm oversized (8.25 mm) autologous penetrating keratoplasty. Intraocular pressure was then set and measured manometrically while being determined successively with each tonometer over the range of 0-65 mm Hg. Linear regression analysis comparing tonometric and manometric readings showed: (1) minified Goldmann applanation tonometer-slope 0.985 and 0.944, intercept 1.64 and 2.55 mm Hg, correlation coefficient 0.99 and 0.99 in same sized and oversized grafted eyes respectively; (2) pneumatonometer-slope 1.008 and 0.990, intercept 3.37 and 3.69 mm Hg, correlation coefficient 0.99 and 0.98; (3) Tono-Pen-slope 1.061 and 1.002, intercept 5.01 and 4.06 mm Hg, correlation coefficient 0.97 and 0.98. We concluded that the minified Goldmann applanation tonometer is as accurate or more accurate than the pneumatonometer and the Tono-Pen in post-mortem post-keratoplasty human eyes, and may be an economical, convenient alternative to the latter two instruments in clinical practice.

    To compare intraocular pressure (IOP) readings between Tono-Pen tonometry and GAT, between noncontact tonometry (NCT) and GAT, and between dynamic contour tonometry (DCT) and Goldmann applanation tonometry (GAT). The correlation between IOP reading and possible confounder was identified. This observational cross-sectional study enrolled sixty-two healthy subjects. All IOP and ocular pulse amplitude (OPA) measurements were taken by a single ophthalmologist; mean keratometric power (MK), central corneal thickness (CCT), and lens thickness (LT) were measured by a single experienced technician. Stepwise multiple regression analysis indicated that GAT (P=0.017) and DCT (P=0.002) readings correlated positively with MK; GAT, NCT, and Tono-Pen readings correlated positively with CCT (P<0.05); NCT (P=0.035), and DCT (P=0.016) readings correlated negatively with LT; GAT (P=0.006) and Tono-Pen (P=0.009) readings correlated positively with OPA. The K, CCT, LT, and OPA are confounders in tonometry readings.

    To assess the validity of the Tono-Pen XL as an alternative to the Goldmann applanation tonometer (GAT) for the measurement of intraocular pressure (IOP) in patients with ocular hypertension (OHT) and glaucoma. Over a 3 month period, patients with OHT or glaucoma attending a general clinic had IOP measurements taken using the Tono-Pen XL and the GAT. Tono-Pen measurements were taken by suitably trained nursing staff, while Goldmann tonometry was performed by the examining ophthalmologist. There were 124 eyes of 62 patients in this study. Overall, mean IOP was 18.3 +/- 4.8 mmHg using GAT and 18.8 +/- 5.5 mmHg using the Tono-Pen. Using the Bland-Altman method, the upper and lower limits of agreement between the two devices were +10.6 mmHg and -9.6 mmHg, respectively. Significant over- and under-estimates of IOP were noted in 10 (16%) patients. Our findings suggest that the Tono-Pen XL cannot be used as a substitute for GAT in the management of patients with glaucoma or OHT.

    In the introduction the authors describe a portable electronic tonometer Tono-pen XL and explain the principle of its function. After this follows a comparative study with Goldmann's applanation tonometry (AT) on 240 eyes in children aged 7 to 18 years. The mean value of the intraocular pressure (IOP) was 17.09 torr +/- 4.35 SD with AT and 16.46 torr +/- 4.04 SD when using the Tono-pen. Regression analysis revealed a very close correlation between the two methods of assessment (r = 0.925) with a high statistical significance (p < 0.0005). The difference as compared with AT values was constant, on average close to -0.68 torr in the whole range from 7 to 35 torr. The authors found also a significantly greater variability of values obtained by means of the Tono-pen (p = 0.0009), the mean scatter of individual values being 1.55 torr as compared with 1.25 torr in AT. However 97.1% of the eyes were within a range of 3 torr. The authors did not find a significant relationship between assessment by means of the Tono-pen and the doctor's experience. The unique advantage of Tono-pen as compared with all other methods of routine tonometry is the relatively accurate assessment of the IOP under irregular conditions of the cornea. It is also possible to take measurements in children where AT cannot be used.

    Water-level/pressure data recorded at a dense network of 16 wells of depths ranging from 23 to 201 m within 400 m of the Tono Mine in Gifu prefecture, central Japan, have been studied in search of possible earthquake-related changes. The study area is traversed by the east-west trending Tsukiyoshi fault, which is ordinarily impermeable, sustaining a significantly higher groundwater pressure on the north side of the fault than the south side. On March 16, 1997, a local earthquake of magnitude 5.8 occurred about 50 km south of Tono. The related water-level/pressure changes recorded at different sites showed different features. At three deeper wells on the north side of the fault the water level and pressure showed large coseismic drops (up to 29 cm) followed by larger rises (of as much as 1.8 m). Two days before the earthquake the water level at another deeper well began to show a total drop of about 3 m during the next 2 months. Most of the shallow wells on the north side of the fault showed water-level drops after the earthquake. On the south side, however, only a small delayed surge and a subsequent gradual increase were recorded at a deeper well. Long-term data since 1989 at one of the deeper wells on the north side showed coseismic drops and recoveries for 25 moderate local and large distant earthquakes up to about 1000 km away. The different observed earthquake-related water-level/pressure changes cannot be explained by the static strain field calculated on the basis of poroelastic dislocation models; the changes require earthquake-related permeability changes at the monitoring sites. The high sensitivity of some of the water wells to seismic shaking may be due to the near-critical condition of the tapped aquifer/barrier system beginning several years prior to the March 16 earthquake, such that the local seismic shaking caused by each of the above mentioned earthquakes was sufficient to produce some quickly recoverable fissures in the system, resulting in the

    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)

    Isotopic studies have been conducted to develop a method to estimate subsurface hydraulic conditions in the granite at the Tono research site, central Japan. The groundwaters were classified into three groups according to residence time, based on the {sup 3}H concentration: (1) modern water recharged from the surface within the last 40 years, (2) a mixture between modern water and relatively old groundwaters, and (3) relatively old groundwater which is devoid of {sup 3}H. An attempt was made to date the {sup 3}H-free groundwater using {sup 14}C. The relative groundwater age estimated by simple model, which assumes no addition of dead carbon ranges from 6500 to 14,000 years B.P. The calcite precipitations on the fracture surface are also classified into three groups, based on carbon isotope compositions: (1) precipitation from groundwater within the last 50,000 years, (2) precipitation from the solution with different {delta}{sup 13}C values from groundwater in the past more than 50,000 years, and (3) mixture of new calcite partly precipitated within the last 50,000 years and relatively old calcite. These data suggest the possibility that the conductive (open) fractures connected to the surface can be estimated by {sup 14}C determination in the calcite on fracture surfaces.

    A new hand-held tonometer, the Tono-Pen (TP), was compared with a Statham membrane manometer (MAN). The TP is a pen-sized Mackay-Marg tonometer with electronic signal analysis and digital pressure display. Comparative measurements of intra-ocular pressure (IOP) were performed on six cadavers (12 eyes in situ), 3-6 hours after death. The IOP was changed in 5 to 10 mm Hg steps in a range between 0 and 60 mm Hg by an infusion system. As compared to the manometrically determined IOP, the TP gave small overestimation of IOP below 17 mm Hg and a small underestimation above 17 mm Hg (maximum deviation 2.5 mm Hg). The mean values of 29.9 (TP) and 30.4 mm Hg (MAN) were not significantly different (p greater than 0.05, analysis of variance). The correlation coefficient was 0.99. The relationship between TP (y axis) and MAN (x axis) pressure readings is characterized exactly by a slightly curvilinear graph (y = 0.82x + 0.0002x2 + 2.52; mm Hg). This may be approximated by a regression line with a slope of 0.94, a y intercept of 1.46 mm Hg and a standard deviation of the TP readings in relation to the regression line of 2.36 mm Hg. In conclusion, the good agreement between TP and MAN pressure readings is superior to the recently described agreement between TP and Goldmann tonometer readings.

    Isotopic studies have been conducted to develop a method to estimate subsurface hydraulic conditions in the granite at the Tono research site, central Japan. The groundwaters were classified into three groups according to residence time, based on the 3H concentration: (1) modern water recharged from the surface within the last 40 years, (2) a mixture between modern water and relatively old groundwaters, and (3) relatively old groundwater which is devoid of 3H. An attempt was made to date the 3H-free groundwater using 14C. The relative groundwater age estimated by simple model, which assumes no addition of dead carbon ranges from 6500 to 14,000 years B.P. The calcite precipitations on the fracture surface are also classified into three groups, based on carbon isotope compositions: (1) precipitation from groundwater within the last 50,000 years, (2) precipitation from the solution with different δ 13C values from groundwater in the past more than 50,000 years, and (3) mixture of new calcite partly precipitated within the last 50,000 years and relatively old calcite. These data suggest the possibility that the conductive (open) fractures connected to the surface can be estimated by 14C determination in the calcite on fracture surfaces.

    A new AMS facility (NEC 15SDH-2) based on a 5 MV tandem accelerator has been installed at the Japan Nuclear Cycle Development Institute (JNC) Tono Geoscience Center in March 1997. It has two cesium sputter negative ion sources (for solid and gas samples) which are connected to a fast sequential injection beam line. A number of performance tests have been done on the MC-SNICS solid source for radiocarbon. Precision measurements with modern samples have shown that a precision below 0.5% is feasible on a routine basis. The 14C background of the machine and the chemistry blank are 0.04 and 0.10 pMC respectively, indicating a 14C dating limit of 56,000 yr BP. The normalized JNC 14C values for IAEA standard materials (C-2 to C-8) agree well with the nominal values. Since October 1998, the MC-SNICS solid source is used for routine radiocarbon dating. Preliminary results of performance tests of the MGF-SNICS gas source are reported, too.

    To find out the effect of central corneal thickness (CCT) and radius of the corneal curvature on intraocular pressure (IOP) measurements using rebound tonometer (RBT) and Tono-Pen in healthy schoolchildren. IOP was measured with Tono-Pen and RBT, respectively, in 165 healthy schoolchildren with a mean age 9.8+/-3.1 (range: 7 to 12 y) years. Corneal radius of curvature (in mm) was determined using a keratometer before CCT and IOP measurements. CCT was measured using an ultrasonic pachymeter after all IOP determinations had been made. The effect of CCT, radius of the corneal curvature, and sex on measured IOP was evaluated by linear regression analysis. The mean IOP readings were 17.47+/-2.7 mm Hg using Tono-Pen, and 16.81+/-3.1 mm Hg using RBT. Tono-Pen measured IOP values slightly greater than that of RBT (P=0.006). Mean CCT was found to be 561.37+/-33 microm. A significant association between measured IOP and CCT was found with each device (r=0.220 for the Tono-Pen, r=0.373 for the RBT; P=0.006 for the Tono-Pen and P<0.0001 for the RBT). The IOP increased 2.2 and 3.7 mm Hg for every 100-microm increase in CCT for the Tono-Pen and the RBT, respectively. The relation between IOP and CCT was not different for boys and girls. Mean radius of the corneal curvature readings was 7.68+/-0.41 mm (42.75+/-1.37 D) for both sexes. There was no significant relationship between either the mean corneal curvature readings, or CCT and IOP (r=0.02; P=0.4 for CCT and r=0.01; P=0.5 for IOP). Both the Tono-Pen and RBT have a systematic error in IOP readings caused by its dependence on CCT. The CCT measurements should be considered to ensure proper interpretation of IOP measurements in children, like in adults. The corneal radius of curvature had no significant effect on measured IOP with each device.

    An environmental survey has been made in the area around Tono mine continuously from 1971 aiming to elucidate the changes in natural environment and the influences of scientific research and industrial development on the surrounding natural environment. In this study, the radioactivities of radon and its daughter nuclides in side the pit of Tono mine were determined and uranium and radium contents in various samples collected around the mine, fine particles in the air, river water, drinking water, soils, etc. were analyzed. The results from the present survey showed that the effects of the mine on the natural environment are not significant. (M.N.)

    To determine the sensitivity and specificity of the Reichert™ Tono-Pen AVIA® when used by novice medical students in an ethnically diverse population in Trinidad. Participants were residents of Trinidad between the ages of 20 and 90 years attending the Ophthalmology Clinic at the Eric Williams Medical Sciences Complex (EWMSC). Intraocular pressure (IOP) was measured using the Goldmann applanation tonometer (the gold standard) for ophthalmology clinic patients as part of their routine care. Intraocular pressure measurements were then taken using the Tono-Pen. One hundred persons participated, consisting of Indo-Trinidadians (55%), Afro-Trinidadians (36%), Mixed (8%) and 1% of Caucasian descent. Fourteen per cent reported a diagnosis of glaucoma, with 70.6% of these being of African descent. One hundred and ninety-eight readings of IOP were taken. At a cut-off point of 21 mmHg, there were nine true positives, four false positives, seven false negatives and 178 true negatives. The sensitivity and specificity were found to be 56.3% (95% CI 33.2, 76.9) and 97.8% (95% CI 94.5, 99.1), respectively. The positive predictive value was calculated as 69.2% (95% CI 42.4, 87.3) while the negative predictive value was 96.2% (95% CI 92.4, 98.2). The prevalence of elevated IOP in this population was 8.1% (95% CI 4.8, 13.0). The likelihood ratio of a positive result was calculated to be 25.6 (95% CI 8.6, 73.9). The high specificity and negative predictive value suggests that the Tono-Pen can be used with minimal training, and can prove beneficial at the primary care level in the exclusion of increased IOP in an ethnically diverse high-risk Caribbean population.

    Water-level data recorded during 1989-1999 at 16 closely clustered wells near the Tono mine in central Japan are searched for possible premonitory changes before earthquakes. The results suggest that some water-level drops at a sensitive well before an M5.8 local earthquake on 1997March 16 and some large distant earthquakes during 1994-1995 in Japan may have been premonitory in nature. The high sensitivity of this well to earthquake occurrence is attributed to the near-critical hydrological conditions and the relatively high permeability of the tapped aquifer.

    In living cynomolgus monkey eyes, the authors compared manometrically set and measured intraocular pressure (IOP) with simultaneous IOP readings obtained with the Tono-Pen (TP), a handheld applanation tonometer based on the Mackay-Marg principle. In three pentobarbital-anesthetized cynomolgus monkeys, IOP was set and measured manometrically after anterior chamber cannulation through the peripheral cornea with a 26-gauge needle connected to a vertically adjustable reservoir and a pressure transducer. Intraocular pressure was raised in approximately 5 mm Hg steps from 5 mm Hg to 60 mm Hg and then lowered in 5 mm Hg steps to 5 mm Hg, with TP measurements taken at each increment and decrement in open and stopcock modes. Linear regression analysis of TP on manometric readings for grouped data from all six eyes, with each data point representing the average of all the TP readings from one eye at each manometric pressure setting, showed a slope 0.692 +/- 0.016 and 0.683 +/- 0.023 (both significantly different from 1; P < 0.001), intercept 1.21 +/- 0.60 and 1.64 +/- 0.82 mm Hg (both significantly different from 0.0, P < 0.05), and correlation coefficient 0.981 and 0.96 in open stopcock and closed stopcock mode, respectively. There were no striking differences when the data were analyzed for individual eyes or animals, for open versus closed stopcock manometry, or for increasing versus decreasing manometric IOP. The TP provides reproducible measurements of IOP in cynomolgus monkeys, with measurement accuracy dependent on the generation of an appropriate calibration curve.

    Levels of organochlorine (OC) and organophosphorus (OP) pesticide residues in fish, sediments and water and their health risk associated with the consumption of the fish from the Tono Reservoir, Ghana were evaluated. The analytical methods included solvent extraction of the pesticide residues using ultrasound sonication and soxhlet extraction and their subsequent quantification using GC equipped with electron capture detector and pulse flame photometric detector after clean-up on activated silica gel/anhydrous sodium sulphate. A total of 29 pesticides comprising 16 OCs and 13 OPs were analyzed, out of which aldrin, p , p '-DDE and p , p '-DDD were detected in fish and sediment samples. The results showed that all the residues in water had their concentrations below the detection limit. Mean concentrations of organochlorine pesticide (OCP) residues in fish ranged from 0.017 to 0.17, 0.043 to 0.30, 0.027 to 0.243 and 0.097 to 0.263 µg/g in Sarotherodon galilaeus , Clarias anguillaris , Schilbe intermedius and Marcusenius senegalensis respectively. Mean concentrations of organophosphates pesticides ranged from 0.080 to 0.090, 0.080 to 0.087 and 0.050 to 0.063 µg/g in C. anguillaris , S. intermedius and M. senegalensis respectively. The level of chlorpyrifos in S. galilaeus was 0.160 µg/g. Mean concentrations of OCP residue in sediments ranged from 0.047 to 0.090 µg/g. Aldrin recorded the highest level while p , p '-DDD recorded the lowest level. The mean concentrations for all the detected residues were below the WHO/FAO maximum residue limits. Health risk estimation revealed that aldrin in M. senegalensis had great potential for systemic toxicity to consumers.

    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{sub 3} type solutions near the surface, changing to Na-HCO{sub 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{sub 2} concentration in the gas phase contacting pore solutions in the overlying soil zone=10{sup -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)

    To compare the effect of using the fingertip of a surgical glove over Ocufilm (Reichert Technologies, NY, USA) on the agreement and reproducibility of measuring intra-ocular pressure (IOP) by the Tono-Pen XL (Reichert Technologies, NY USA). Experimental, clinical study. Patients were randomized into two groups to receive IOP measurements using Tono-Pen XL with two different types of tip covers. In Group 1, the IOP of the right eyes were first measured using Ocufilm as the tip cover followed by using the fingertip of a surgical glove. As for the left eyes, the tip of the surgical glove was used first, followed by use of Ocufilm. In Group 2, the IOP of the right eyes was first measured using the tip of the surgical glove,followed by use of Ocufilm, while for the left eye the latter was used first, followed by the tip of the surgical glove. A single operator measured the IOP in each eye twice using each type of tip cover. Agreement between the Tono-Pen XL measurements using the two different tip covers was analyzed using the Bland-Altman analysis. The difference between the repeated measures was assessed for reproducibility of the Tono-Pen XL measurements with regard to each type of tip covers. 100 patients (200 eyes) were recruited into the present study. The mean difference of IOP taken by the Tono-Pen XL covered with Ocufilm and the fingertip of a surgical glove was -0.21 mmHg (95% CI: -0.36 to -0.05). The limits of agreement (confidence interval 95%) as calculated by the Bland-Altman plots for Ocufilm-Fingertip of a surgical glove was -2.43 to +2.02 mmHg. The coefficient of repeatability of the Ocufilm vs. the surgical glove was nearly the same (1.74 vs. 2.37, respectively). A significant agreement exists between using Ocufilm and the fingertip of a surgical glove to cover the tip of a Tono-Pen XL for measuring IOP The coefficient of repeatability was comparable between the two different types of tip covers. When measuring IOP the tip of a Tono-Pen XL could

    To evaluate the influence of keratometric measurements on the concordance of intraocular pressure (IOP) readings with three applanation tonometers. The IOPs of 404 eyes of 202 patients from a general eye clinic were measured by Goldmann, Tono-Pen XL, and noncontact Nidek NT 2000 tonometers. Differences in the IOP measurements between Goldmann and the other two tonometers (deltaIOPG-TP and deltaIOPG-NCT) were analyzed in the overall group and within three subgroups based on keratometry measures: flatter, intermediate, and steeper corneas (quartiles as cut-off points). Regression analysis of deltaIOP and keratometry measures was also performed. Right and left eyes were analyzed separately. The IOP readings taken with the Goldmann tonometer were significantly higher than those taken with either of the other two tonometers within the overall study population. The deltaIOP within the three keratometric subgroups was not statistically significant except for deltaIOPG-TP in the right eyes. Regression analysis showed that keratometry and deltaIOPG-TP and deltaIOPG-NCT had a significant but very weak coefficient of correlation in the right eye, but not in the left. Corneal curvature within the normal range does not have a clinically significant influence on the concordance of IOP readings obtained with Goldmann and Tono-Pen or noncontact tonometers.

    The chemical properties of groundwater are one of the most important factors governing radionuclide migration in geological formations, and often determined by the use of boreholes. In this paper, a groundwater sampling procedure is described and the status of geochemical investigation of groundwater in Tono area (Japan) is presented. A sampling procedure using two-component mixing equation and continuous monitoring is proposed for the characterization of groundwater chemistry. Concentration of chemical components in formation water can be estimated even in the case of uncompleted groundwater sampling campaign due to mechanical troubles with groundwater sampler, time limitation for field investigation, and measurement in low permeability rock, by using this procedure. The chemical property of groundwater in the Tono sedimentary rocks varies from Ca 2+ -HCO 3 - type to Na + -HCO 3 - type depending on the depth. The comparison between stable and radioactive isotope data suggests that groundwater of the lower aquifer is of meteoric origin and is dated to the late Wurm glacial stage.

    To compare the accuracy between two applanation tonometers, Tono-Pen XL(®) and Perkins(®), in ophthalmoscopically normal dogs and cats. Both eyes of 25 conscious and healthy dogs and cats were evaluated. Both eyes of five dogs and cats immediately after sacrifice were used as controls for the postmortem study. In conscious animals, the tonometry was performed with topical anesthesia using 0.5% proxymetacaine eye drops for both tonometers and 1% fluorescein eye drops for the Perkins tonometer. Readings of intraocular pressure (IOP) in the postmortem study were taken using manometry and tonometry by Tono-Pen XL(®) and Perkins(®). The correlation coefficient (r(2) ) in dogs between manometry and applanation tonometers Tono-Pen XL(®) and Perkins(®) were, respectively, 0.896 and 0.981 and in cats were 0.905 and 0.988. The mean IOP values in conscious dogs with Tono-Pen XL(®) and Perkins(®) were, respectively, 17.5 ± 3.7 mmHg (10.0-25.0 mmHg) and 15.3 ± 2.1 mmHg (12.0-19.8 mmHg) and in conscious cats were 16.8 ± 3.6 mmHg (10.5-24.5 mmHg) and 15.5 ± 1.3 mmHg (13.0-18.5 mmHg). There was a strong correlation between the IOP values obtained by direct ocular manometry and the Tono-Pen XL(®) and Perkins(®) tonometers in dogs and cats. There was no statistically significant difference between the mean IOP obtained with both tonometers in conscious animals, there was, however, a difference between the minimum and mainly in the maximum values that were on average 5-6 mmHg higher with Tono-Pen XL(®) than those measured with Perkins(®), which justifies a table of normal values differentiated for each tonometer. © 2012 American College of Veterinary Ophthalmologists.

    Among other corneal biomechanical properties, Goldmann applanation tonometry (GAT) has been shown to depend on corneal edema. New tonometry devices have been designed, such as the Tono-Pen XL, iCare, and ocular response analyzer (ORA), to measure the intraocular pressure (IOP) accurately. This study aims to investigate the influence of corneal edema on the accuracy of these IOP-measuring devices in an in vitro model. A model of an artificial anterior chamber was developed using a guided trephination system. Eight donor corneas not suitable for keratoplasty were clamped into this artificial anterior chamber. All corneas showed signs of stromal edema. Intracameral pressure (ICP) was adjusted manometrically to 10, 20, 30, 40, and 50 mm Hg. The central corneal thickness (CCT) was determined by ultrasonic pachymetry. For each manometrically defined ICP, tonometry was performed using the iCare, Tono-Pen XL, GAT, and ORA. The mean CCT increased from 616.1±29.6 µm to 626.9±36.1 µm. At 10 mm Hg, GAT yielded a higher ICP than those manometrically adjusted (10.4±3.3 mm Hg); at all other ICP levels, GAT yielded lower ICP levels than those adjusted. The Tono-Pen XL and iCare showed the greatest difference at 10 mm Hg, with the Tono-Pen XL yielding a value of 14.0±4.0 mm Hg and the iCare yielding a value of 12.5±2.6 mm Hg. All other results of the 2 devices fell within a range of ±2 mm Hg from the adjusted ICP. The ORA provided accurate results only at "physiological" ICP levels with a maximum difference of 2.6 mm Hg at 30 mm Hg. At higher ICP levels, corneal hysteresis decreased significantly with increasing ICP. None of the measurement devices revealed a statistically relevant dependence on CCT in this experimental setting. The Tono-Pen XL and the iCare yielded the most accurate ICP values across all the adjusted ICP values. This may be because of their relatively small contact area with the cornea and, consequently, greater independence from corneal biomechanical

    In this study, the concept and possible uses of artificial neural network (ANN) for mapping hydraulic pressures within boreholes are presented. ANN models were developed using monitored hydraulic pressure data over a certain period representing near-natural conditions to map the fluctuating patterns of hydraulic pressure in deep geologic formations in the Tono area, Japan. The ANN models developed captured the natural effects due to barometric pressure, earth tides, and other factors. It was also observed that geologic structures such as the Tsukiyoshi Fault divided the groundwater flow domains in the area. The formulated models that satisfactorily captured those natural effects were then used to evaluate the effect of pumping over a different period.

    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)

    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.

    In order to explore the difference of intraocular pressure (IOP) at different points of cornea before and after laser in situ keratomileusis (LASIK), IOP was measured by Tono-Pen Tonometer at central cornea, pericentral cornea and limbus respectively and analyzed statistically. After LASIK, IOP was dropped significantly at central cornea and pericentral cornea (P0.05). There was no statistically significant difference in IOP at different points before LASIK (F=0.110, P=0.896), but statistically significant difference was found after LASIK (F=7.375, P=0.001). It was suggested that reliable IOP after LASIK could be obtained from the limbus by Tono-Pen tonometer.

    The Tono Geoscience Center (TGC) has been developing the GEOMASS system since 1997 to evaluate the groundwater flow at depth in a rock mass. The system provides an integrated simulation system environment for both model development and groundwater flow simulations. The integrated simulation system allows users to use resources efficiently. The system also allows users to make rapid improvement of their models as data increases. Also, it is possible to perform more realistic groundwater flow simulations due to the capability of modeling the rock mass as a continuum with discrete hydro-structural features in the rock. TGC tested the operation and usefulness of the GEOMASS system by applying to groundwater flow simulations in the Tono area, Gifu Prefecture. TGC confirmed that the system is very useful for complex geological models and multiple modeling. (author)

    To evaluate the effect of mild to moderate myopic correction by laser-assisted in situ keratomileusis (LASIK) on intraocular pressure (IOP) measurements with three tonometers: the Goldmann applanation tonometer, Tono-Pen, and pneumatonometer. In a prospective study of a clinic-based population undergoing elective LASIK surgery for myopia correction, IOP measurements were obtained preoperatively and postoperatively with a Goldmann applanation tonometer, Tono-Pen, and pneumatonometer. Central corneal thickness and keratometric and astigmatism measurements were also obtained before and after surgery. A paired test was used to evaluate the significance of differences between preoperative and postoperative IOP measurements with each instrument. Linear regression was used to correlate IOP measurements with degree of myopia corrected, astigmatism, and central corneal thickness before and after surgery. The study included 66 eyes of 34 individuals with a mean preoperative refractive error of -5.66 + 2.3 D (mean + SD). The reduction of central corneal thickness after LASIK of 0.032 + 0.030 mm (mean + SD) was statistically significant ( < 0.0001). However, there was no statistically significant change in mean IOP after the procedure with the Goldmann applanation tonometer or the Tono-Pen, while the pneumatonometer, was associated with a small but statistically significant decrease in mean IOP of 1.1 mm Hg. In this group of patients with mild to moderate myopia, LASIK had little or no statistically significant influence on IOP readings obtained with a Goldmann applanation tonometer, Tono-Pen, or pneumatonometer. This finding is in contrast to earlier reports of greater amounts of myopic correction, in which significant reductions in measured IOP were observed. Further study is needed to determine whether a critical amount of corneal change after LASIK is required to have a significant effect on IOP measurements.

    To determine the effects of probe orientation on the accuracy of intraocular pressure (IOP) measurements obtained with pneumatonometry (Model 30 Classic Pneumatonometer, Reichert Ophthalmic Instruments, Depew, NY) and with a handheld electronic tonometer (Tono-Pen XL, Reichert Ophthalmic Instruments, Depew, NY). Six enucleated human eyes were obtained fewer than 24 hours postmortem. IOP was maintained at 10, 20, and 30 mm Hg, sequentially, via liquid column manometry. At each IOP setpoint, the eyes were positioned to mimic a sitting, supine, and prone patient. Pneumatonometry was performed in the sitting and supine orientations. Tono-Pen measurements were performed in the sitting, supine, and prone orientations. Accuracy was analyzed using multifactor repeated measures analysis of variance, and one-sample t tests. At all IOP setpoints, for both instruments, probe orientation had no significant effect on the IOP measurement (pneumatonometer P=0.58; Tono-Pen P=0.85). At all 3 setpoints (10, 20, and 30 mm Hg) the pneumatonometer overestimated IOP (P<0.0001; P<0.0001; P=0.005, respectively). The Tono-Pen overestimated IOP at the 10 mm Hg setpoint (P<0.0001), but underestimated IOP at the 20 and 30 mm Hg setpoints (P=0.03; P<0.0001, respectively). Under experimental conditions, probe orientation had no significant effect on IOP measurements for either instrument, suggesting that both can be used without correction in the tested orientations. In enucleated human cadaveric eyes, the pneumatonometer overestimated IOP at all setpoints. The handheld electronic tonometer overestimated IOP at 10 mm Hg, but underestimated IOP at the higher setpoints. It is unknown if these findings are generalizable to human eyes in vivo.

    This report presents work undertaken by Richard Metcalfe, during a JNC International Fellowship, between 1st March 1999 and 28th February 2002. During this period, the main purpose of the work was continuous review and appraisal of geochemical studies being done by the Japan Nuclear Cycle Development Institute (JNC) and contribution to a range of specific geochemical studies. This involved working closely with Japanese colleagues at Tono Geoscience Center (TGC) and included the following major activities: assistance with the production of the English language version of the Second Progress Report (H12); contribution to the construction of a geochemical database for the Tono area; interpretation of groundwater and mineralogical chemical data from the Tono area; interpretation of rock chemical and mineralogical data from the Tsukiyoshi Fault zone; development of a new statistical method for investigating groundwater mixing; review of investigations in a new, inclined deep borehole (MIU-4); contribution to planning the Mizunami Underground Laboratory (MIU); publication of results (two papers in press at the time of completion); dissemination of results at conferences. These activities were very broad in scope and produced a wide range of different outputs. However, a dominant theme was the application of geochemical information to understand past and present groundwater flow. The present report aims to compile those outputs from the Fellowship that deal with this theme. (author)

    Full Text Available AIM: Tono-pen measurement of intraocular pressure (IOP under topical anaesthesia in full term normal newborns.METHODS: The IOP measurements were taken using Tono-pen XL tonometer under topical anaesthesia in 150 newborns (300 eyes within 24h after birth, over a period of three months, in a university hospital. Gender, gestation period, mode of delivery and birth weight of newborns were noted from medical records.RESULTS:There were 70 males and 80 females. All babies were Malays. The IOP measurements were taken between 12 and 24h after birth. The gestation period of babies ranged between 37 and 41 weeks; 118 babies were delivered by spontaneous vaginal delivery and 32 by caesarian section. The birth weight of babies ranged between 2.1 and 4.3kg. The mean IOP of 300 eyes was 15.99±2.79mmHg (range 8-22. There was no statistically significant difference of mean IOP and gender, laterality of eye, type of delivery, gestation age, or birth weight of newborns.CONCLUSION: The IOP in full term normal newborns was 16mmHg. Tono-Pen appears to be ideal instrument for taking IOP in newborns because of its small size and easy handling.

    The aim of this study was to compare intraocular pressure (IOP) measured with the Tono-Pen® to that measured using the Goldmann applanation tonometer (GAT) in patients with primary open angle glaucoma attending a glaucoma clinic. A comparative clinic-based observational study was conducted involving 75 patients (39 men and 36 women) attending a glaucoma clinic in Southwest Nigeria. A pretested structured questionnaire was used to collect sociodemographic data. The Tono-Pen and the GAT were used to measure the IOP in each patient. Central corneal thickness (CCT) was measured with an ultrasonic pachymeter, and the corrected GAT value was calculated for each patient. The Tono-Pen readings were compared with the uncorrected and corrected GAT readings. Descriptive and comparative analyses were performed. Values for p < 0.05 were considered statistically significant. The mean age of the participants was 60.39 ± 16.71 years. The mean IOP using the Tono-Pen was 21.1 ± 6.8 mm Hg versus the mean uncorrected GAT value of 17.1 ± 6.9 mm Hg and the corrected GAT value of 18.9 ± 7.5 mm Hg. The mean CCT was 510.5 ± 29.6 µm. The mean differences between the Tono-Pen reading and uncorrected and corrected GAT readings were 3.9 ± 2.6 and 2.1 ± 3.5 mm Hg, respectively. Gender (Tono-Pen vs. GAT; p = 0.981 vs. 0.437) and corneal thickness (p = 0.057) did not significantly affect the IOP value. Of the 75 patients, 68 (90.7%) preferred the Tono-Pen to the GAT. In this study, the Tono-Pen gave a higher value for IOP than the uncorrected and corrected GAT values. Gender and corneal thickness did not significantly affect the measurements. Most patients found the Tono-Pen more acceptable than the GAT. © 2016 S. Karger AG, Basel.

    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.

    Groundwater dating was performed simultaneously by the 4He and 14C methods in granite of the Tono area in central Japan. Groundwater was sampled at 30 packed-off sections of six 1000-m boreholes. 4He concentrations increased and 14C concentrations decreased along a groundwater flow path on a topographic gradient. 4He ages were calculated by using the in situ 4He production rate derived from the porosity, density, and U and Th content of the rock, neglecting external flux. 14C ages were calculated with a noncorrected model in which the initial 14C content was 100 percent of the modern radiocarbon level (Co = 100 pmC), a statistical model using the average 14C content of tritium-bearing samples (Co = 46.4 pmC), and a δ13C model based on the isotopic mass balance. Although the absolute 14C ages calculated by the models were different, the relative 14C ages were almost identical. The relative 14C ages were considered reliable because dissolved inorganic carbon has no significant geochemical reactions in granite. The relation between the 4He ages and the noncorrected 14C ages was [4He age] = 1.15 [14C age] + 7200 (R2 = 0.81), except in the discharge area. The slope of this relation was equivalent to unity, which indicates that the 4He accumulation rate is confirmed by the relative 14C ages. Moreover, the accumulated 3He/4He ratio was equivalent to that derived from the 6Li(α,n)3H reaction in granite. These results show that the accumulated He is of crustal origin, produced in situ without external flux, except in the discharge area. The intercept value of 7200 a implies that the 14C concentrations were diluted due to geochemical reactions. Tritium-bearing samples supported this result. Simultaneous measurements make it feasible to estimate the accumulation rate of 4He and initial dilution of 14C, which cannot be done with a single method. Cross-checking groundwater dating has the potential to provide more reliable groundwater ages. The circulation time of the

    Human- and snail-related aspects of transmission of urinary and intestinal schistosomiasis were studied in the Tono Irrigation Scheme in northern Ghana. The scheme became operational in 1977. In some schools, prevalences and intensities of both Schistosoma mansoni and S. haematobium infection were alarmingly high, pointing to human schistosomiasis being at least focally a health problem of major public health concern. Positive correlations between intensity of schistosome infection, as measured by egg output, with frequency of visible haematuria and history of haematuria point to opportunities for community-based assessment of morbidity and identification of high risk population subgroups. Bulinus globosus is the most important snail host for S. haematobium while Biomphalaria pfeifferi serves as host for S. mansoni. While transmission of S. mansoni is taking place only in the main canal, transmission of S. haematobium takes place in all parts of the irrigation system (lateral canal, night storage dam, main reservoir). Transmission of both S. mansoni and S. haematobium is rather focal and a seasonal pattern of transmission is indicated with peak transmission taking place during the beginning of the dry season. The high endemicity and the transmission patterns described in this study call for an integrated approach to schistosomiasis morbidity control in the area.

    Full Text Available The objective of this study was to compare the accuracy between two applanation tonometers, Tono-Pen XL® and Perkins®, in horses and cattle. The eyes of 20 horses and 20 cattle conscious and healthy were evaluated for the in vivo study and both eyes of 5 horses and 5 cattle were used as controls for the postmortem study. In conscious animals, the tonometry was performed with auriculopalpebral nerve block and then topical anesthesia for both tonometers and 1% fluorescein eye drops only for the Perkins tonometer. Readings of intraocular pressure (IOP in the postmortem study were taken using manometry and tonometry by Tono-Pen XL® and Perkins®. The correlation coefficient (r² between manometry and applanation tonometers Tono-Pen XL® and Perkins®, in horses, were 0.845 and 0.989, respectively, and in cattle, were 0.772 and 0.988, respectively. The mean IOP values in conscious horses with Tono-Pen XL® and Perkins® were 20.1±3.9mmHg and 20.9±3.2mmHg, respectively, and in conscious cattle, these values were 17.2±2.4mmHg and 17.9±1.4mmHg, respectively. There was a strong correlation between the IOP values obtained by direct ocular manometry and the Tono-Pen XL® and Perkins® tonometers in horses and cattle. There was no statistically significant difference between the mean IOPs obtained with both tonometers in conscious animals; however, there was a difference between the minimum values, which were on average 2-3 mmHg lower with the Tono-Pen XL® tonometer than with the Perkins® tonometer, which justifies a table of normal values differentiated for each tonometer.O objetivo deste estudo foi comparar a acurácia entre dois tonômetros de aplanação, Tono-Pen XL® e Perkins®, em equinos e bovinos.

    Faults are commonly believed to act as either barriers to horizontal ground-water flow normal to the fault, conduits to horizontal flow parallel to the fault, or a combination of both. In addition, enhanced vertical permeability has also been observed as a common feature. We use numerical modeling to investigate the effects of vertical anisotropy of a dipping fault zone on the distribution of hydraulic head within and around the fault. The Tsukiyoshi Fault in the Tono region of Japan extends through the center of the assessment area and has an E-W strike. According to the results of borehole investigations, the fault has N80W strike, 70 degree dip, 10-30 m width and approximately 30 m vertical off-set. Model results show that for anisotropy ratios (A = kz/kx) of greater than 100, hydrostatic conditions are achieved within the fault zone, despite the existence of significant vertical flow rates. A hydraulic head difference of about 40 m across the fault is observed and confirmed by our model, suggesting that the fault acts as barrier to flow normal to it. We consider the pressure response to two shafts pumping in the upper parts of the fractured granitic formation near the fault. The response to pumping is monitored at two boreholes (DH-15 and DH-2) on the same side of the fault as the pumping shafts. The responses at the two boreholes are vertically invariant and highlight the effects of enhanced vertical permeability around the fault. This suggests that the fault controls the hydrology in this area. Particle tracking is used to investigate and demonstrate the effects of the fault on pathlines.

    Qualitative evaluation of the effects of uncertainties originating from scenario development, modeling approaches, and parameter values is an important subject in the area of safety assessment for high-level nuclear waste disposal sites. In this study, regional-scale groundwater flow analyses for the Tono area, Japan were conducted using three continuous models designed to handle heterogeneous porous media. We evaluated the simulation results to quantitatively analyze uncertainties originating from modeling approaches. We found that porous media heterogeneity is the main factor which causes uncertainties. We also found that uncertainties originating from modeling approaches greatly depend on the types of hydrological structures and heterogeneity of hydraulic conductivity values in the domain assigned by modelers. Uncertainties originating from modeling approaches decrease as the amount of labor and time spent increase, and iterations between investigation and analyses increases.

    We have developed a digital multi-component borehole instrument for boreholes deeper than 1 km and with diameters smaller than 98 mm, and installed it at the bottom of seven deep boreholes in the Tono region, central Japan. So far, our borehole instruments have observed not only tidal signals, but also strain-steps associated with large earthquakes, and environmentally induced signals. In this study, we analyze the strain data from four observation sites using the tidal analysis program BAYTAP-G and compare the tidal amplitudes of strain with in situ rock properties. We observed an obvious difference in amplitude and phase of the M2 and O1 tidal strains from four observation sites that are located in the same Toki granite bedrock within a distance of 10 km. There are strong negative correlations between the semi-diurnal E-W, areal tidal strain and in situ rock hardness (shear modulus and Young's modulus), while N-S tidal strain is unrelated. In contrast, strain-steps associated with large earthquakes increase with hardness, as observed at two sites. We consider that the inconsistency of the behavior of the tidal amplitudes and strain-steps may be caused by the heterogeneity of rocks near the borehole strainmeters.

    Full Text Available The fact that so many Villancets and Tones by the composer Francesc Valls (*1671c; †1747 are preserved, lead me to check and contrast the formers with the latters, in order to guess which could be possible coincidences and differences between these two musical “styles”, so similar in structure, at least in their beginning. Following, I will offer the process and results of my study, as a posthumous homage to my teacher, Dr. Miquel Querol, and also as a further contribution to the study of this subject.

    Icare PRO (ICP) is a new Rebound tonometer that is able to measure intraocular pressure (IOP) in both sitting and reclining positions. In this study, the gold standard Goldmann tonometer (GAT) was compared to ICP and Tono-Pen AVIA (TPA). Hypothesis was that repeatability of GAT is superior to ICP and TPA. 36 eyes of 36 healthy caucasian individuals, 13 male and 26 females, 17 right and 19 left eyes have been included in this prospective, randomized, cross-sectional study. The study was conducted at a single site (Dept. of Ophthalmology, University Hospital Zurich, Switzerland). Primary outcome measures were Intraclass correlation coefficients (ICC) and coefficients of variation (COV) and test-retest repeatability as visualized by Bland-Altman analysis. Secondary outcome measures were IOP in sitting (GAT, ICP and TPA) and in reclining (ICP and TPA) position. Mean IOP measured by GAT was 14.9 ± 3.5 mmHg. Mean IOP measured by ICP was 15.6 ± 3.1 mmHg (with TPA 14.8 ± 2.7 mmHg) in sitting and 16.5 ± 3.5 mmHg (with TPA 17.0 ± 3.0 mmHg) in reclining positions. COVs ranged from 2.9% (GAT) to 6.9% (ICP reclining) and ICCs from 0.819 (ICP reclining) to 0.972 (GAT). Repeatability is good with all three devices. GAT has higher repeatability compared to the two tested hand-held devices with lowest COVs and highest ICCs. IOP was higher in the reclining compared to the sitting position. The study was registered to the Clinical Trials Register of the US National Institute of Health, NCT01325324.

  18. Redox buffer capacity of sedimentary rocks around uranium deposit. Study of water-mineral-microbe system at the Tono uranium deposit, Japan

    The redox buffer capacity of the water-mineral-microbe system in and around the Tono uranium deposit, Japan, was studied to evaluate the long-term stability of the redox system. The uranium deposit occurs in the lower part of a Miocene sedimentary rock sequence that unconformably overlies granite. In the groundwater, profiles of redox sensitive solutes such as sulphate and sulphide ions, abundance and viability of microbes, and sulphur isotope ratios of sulphate ions suggest that microbial sulphate reduction involving organic matter and subsequent pyrite precipitation are dominant redox reactions at the depths of the uranium ore bodies. Concentrations of both the sulphate and chloride increase with increasing depth. The dissolved sulphate is surmised to have originated from dissolution of sulphate and sulphide minerals in a geologic marine formation precipitated in marine environments, in the upper part of the sedimentary rocks. Such a redox process in the water-mineral-microbe system is inferred to have continued from the time when the marine formation underwent uplift above sea-level, because sulphate-reducing bacteria can use sulphate ions dissolved in fresh water that infiltrates from the marine formation and organic matter located in the deeper sedimentary rocks. The chloride ion also has a linear relationship with groundwater residence time. from the relationship between sulphate and chloride ion concentrations, the sulphate ion dissolution rates from the marine formation are estimated at about 5.9 x 10{sup -5} mM/yr. Calculations by using the sulphate-S contents of the rocks and the sulphate dissolution rate suggest that microbial sulphate reduction alone could maintain sufficiently reducing conditions to preserve the uranium ore for several hundred thousand years, in the case where a hydrogeological system continues to exist without much change.

    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.

    Full Text Available Purpose. To investigate the repeatability and reproducibility of intraocular pressure (IOP and central corneal thickness (CCT measurements using a noncontact tono/pachymeter (NT-530P and to assess the correlation of CCT with IOP. Methods. Forty-six eyes of healthy volunteers were measured by two examiners. Three consecutive measurements per eye were performed. Repeatability was assessed using the coefficient of variation, and reproducibility was assessed using Bland-Altman plots. Linear correlations were used to determine agreement between CCT and noncorrected IOP and CCT and corrected IOP, which was calculated using a formula built into the NT-530P. Results. The coefficient of variation for IOP was 6.4% and for CCT was 0.4%. The 95% limits of agreement between examiners were −0.17±1.42 mmHg (range: −2.95 to 2.61 mmHg for IOP, −0.93±4.37 μm (range: −9.50 to 7.64 μm for CCT. The corrected IOP was significantly higher than the noncorrected IOP (P=0.010.3. The noncorrected IOP significantly correlated with CCT (r=−0.4883, P=0.0006. The corrected IOP showed no significant correlation with CCT (r=−0.0285, P=0.8509. Conclusions. NT-530P offered repeatability and reproducibility in both IOP and CCT measurements. The corrected IOP calculated using the NT-530P was independent of the CCT, suggesting that this IOP may be less influenced by the central corneal thickness.

    To estimate agreement in diurnal variations of intraocular pressure (IOP) by Tono-Pen (TP) and Goldmann applanation tonometer (GAT) in glaucoma patients on topical anti-glaucoma medication(s). IOP was measured at every 3 h from 7 a.m. to 10 a.m. in 50 eyes of glaucoma patients on topical medication(s). Diurnal fluctuation of IOP by each method was calculated as maximum-minimum IOP in a day. Central corneal thickness (CCT) was measured by ultrasonic pachymeter. There was good correlation between TP and GAT at all times during a day, minimum, and maximum IOPs during a day (Correlation coefficient, 0.706 at 7 a.m., 0.624 at 10 a.m., 0.682 at 1 p.m., 0.814 at 4 p.m., 0.652 at 7 p.m., 0.572 at 10 p.m., 0.668 minimum IOP, 0.689 maximum IOP). Mean IOPs by TP were always higher than GAT at all times during a day. Bland-Altman plots suggested a close relationship between the two sets of readings, and that this relationship was consistent at different times in a day, in maximum IOPs, minimum IOPs and also in fluctuation of IOPs. Linear regression analysis between the differences of diurnal fluctuation (diurnal fluctuation by GAT-diurnal fluctuation by TP) and CCT showed strong association (R 2 = 0.857, p < 0.001). The mean change in difference of diurnal fluctuation (GAT-TP) for a 10-micron increase in CCT was 0.69 mmHg. TP can be considered a reliable alternative to GAT in glaucoma patients for knowing the diurnal control of IOP; however these two methods should not be used interchangeably. Difference of diurnal fluctuation between two methods is dependent on CCT.

    SummaryBy modifying a previous method with constant elements, we developed a quadratic element method for more accurately estimating groundwater flow by the inversion of tilt data. In this method: (1) a region of groundwater flow is divided into quadratic elements in which the change in groundwater volume per unit volume of rock (Δ v) and the Skempton coefficient ( B) vary in a quadratic manner with the coordinates, (2) the values of Δ v are set to zero at the boundaries of the region of groundwater flow and (3) the sum of the squared second derivatives of Δ v is adopted as a constraining condition that is weighted and added to the sum of the squared errors in tilt. First, analyses were performed for a flow model to determine the accuracy of this method for estimating groundwater flow and also to clarify the effect of the assumed size of a region of groundwater flow. These analyses showed that the quadratic element method proposed in this study gives a much better estimation of Δ v than the constant element method and that a large region of groundwater flow should be assumed, rather than a small region, since the values of Δ v at points outside of the actual region of groundwater flow are estimated to be nearly zero when a large region is assumed while these values are greatly overestimated when an excessively small region is assumed. Finally, the quadratic element method was applied to the site of the Mizunami Underground Research Laboratory in the Tono area, Japan. Inverse analyses were performed for tilt data measured by four tiltmeters with a resolution of 10 -9 radians during the excavation of two shafts under the assumption that the rock mass is an isotropic and homogeneous half- space. The results showed that the method proposed in this study reproduced the tilt data very accurately. Thus, the distribution of Δ v was estimated without sacrificing the reproducibility of the tilt data. The contour maps of B(1 + ν)Δ v ( ν: Poisson's ratio) showed that

    Full Text Available En la presente investigación de tipo descriptivo, comparativo y explicativo, se analizó el fenómeno de discordancia entre el complemento indirecto y el pronombre átono que lo duplica en la oración, en un corpus tomado del periódico El Colombiano, versión digital. Con la ayuda del software Cratilo® se encontraron frecuencias de uso tanto de la discordancia como de la concordancia, se analizaron las estructuras gramaticales de las oraciones, el número del sujeto de las mismas, la referencia del complemento indirecto a cosa y a persona, y se compararon los resultados. Se concluyó que no hay una única explicación para el uso de la discordancia y que probablemente se trate del fenómeno denominado fosilización. Lo que sí pudo comprobarse es que la discordancia abunda más cuando el pronombre átono aparece en la oración antes que el complemento.In this descriptive, comparative and explanatory research, the phenomenon of discordance is examined between the indirect object and the atonic pronoun that doubles it in the sentence, in a corpus taken from the digital version of El Colombiano newspaper. With the help of Cratylus ® software frequencies of use of the discordance as well as the concordance were found, the grammatical structures of sentences, their grammatical number, the indirect object reference to thing and person was analyzed and finally results were compared. It is concluded that there is not only one explanation for the use of the discordance and probably it is a question of the phenomenon called fossilization. What indeed could be proved is the high frequency of disagreement detected in the cases when the atonic pronoun precedes the direct complement in the sentence.

The right eyes of 105 subjects aged 18 to 82 years (mean age = 29.27 ± 14.67 years were assessed with the three tonometers. Central corneal thickness (CCT was measured first using the Tonopachy™ and then IOP was measured by Tonopachy™, iCare® and GAT. 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™.

A cultura do sorgo seria alternativa no período da seca na produção de silagem para o período das águas; contudo, o crescimento e desenvolvimento das plantas pode ser influenciado por alterações nos atributos do solo, como textura, porosidade e estrutura do solo. O objetivo deste trabalho foi analisar e caracterizar a dependência e variabilidade espacial entre atributos do solo e a cultura do sorgo forrageiro, em um Planossolo Hidromórfico no ecótono Cerrado-Pantanal. Para tanto, estimaram-se a produtividade de matérias verde e seca de forragem (MVF e MSF de sorgo forrageiro e os atributos do solo, como macroporosidade (Ma, microporosidade (Mi, porosidade total (Pt, diâmetro médio geométrico, diâmetro médio ponderado, índice de estabilidade de agregados (IEA e teor de carbono orgânico total do solo (COT, em duas profundidades: 1 (0,00-0,10 m e 2 (0,10-0,20 m. Em relação à malha geoestatística, foram realizadas 50 coletas de atributos de planta e solo em 40 ha. Isso possibilitou detectar a elevada variabilidade espacial dos atributos de planta (MVF e MSF e também os atributos do solo que mais variaram espacialmente. Com relação às variáveis que apresentaram dependência espacial, o coeficiente de determinação (r2 decresceu na seguinte ordem: IEA1, silte2, Ma1, Pt1, areia2, silte1, MSF, argila1, MVF e IEA2. Com isso, verificou-se que IEA1 apresentou o melhor ajuste semivariográfico (r2 = 0,926, com alcance de 677,0 m, e o avaliador da dependência espacial (50,6 % moderado. O silte1, porém, evidenciou o menor alcance (111,0 m e, assim, recomenda-se que em estudos posteriores o alcance mínimo a ser adotado, para esse tipo de avaliação, não deve ser inferior a esse valor em Planossolo Hidromórfico sob preparo convencional.

El portavoz, concebido como una forma particular de conducta política, permite esbozar la emergencia de la modernidad política a partir de sujetos imbricados en un complejo haz de preconstruidos culturales insertos en la filiación ilustrada y romántica. La delimitación del ethos conlleva a considerar la imagen del sujeto a partir del tono, del cuerpo y del carácter discursivo, encastrados en diversas huellas del lenguaje. Finalmente, la instauración de una comunidad discursiva, definida como la cara social de toda formación discursiva, posibilita aunar el vínculo entre la constitución de un modo de decir -de un lenguaje, de un sistema de representaciones- y de un orden político. A partir de estas estrategias se traza uno de los modelos discursivos del hispanoamericanismo, que será retomado y reformulado en posteriores procesos históricos, para expandir una memoria discursiva latinoamericana posicionada en la necesidad de implementar la integración regional.Starting from the papers published in Gaceta de Buenos Aires by Bernardo Monteagudo between 1811 and 1812, in this work we present the shaping of a discourse tradition zone of the Hispanic-Americanism revolution discourse in the nineteenth century.

    Microorganisms are ubiquitous in deep subsurface environments, but their role in the global carbon cycle is not well-understood. The natural abundance δ13C and Δ14C values of microbial membrane phospholipid fatty acids (PLFAs) were measured and used to assess the carbon sources of bacteria in sedimentary and granitic groundwaters sampled from three boreholes in the vicinity of the Tono Uranium Mine, Gifu, Japan. Sample storage experiments were performed and drill waters analyzed to characterize potential sources of microbial contamination. The most abundant PLFA structures in all waters sampled were 16:0, 16:1ω7c, cy17:0, and 18:1ω7c. A PLFA biomarker for type II methanotrophs, 18:1ω8c, comprised 3% and 18% of total PLFAs in anoxic sedimentary and granitic waters, respectively, sampled from the KNA-6 borehole. The presence of this biomarker was unexpected given that type II methanotrophs are considered obligate aerobes. However, a bacterium that grows aerobically with CH4 as the sole energy source and which also produces 56% of its total PLFAs as 18:1ω8c was isolated from both waters, providing additional evidence for the presence of type II methanotrophs. The Δ14C values determined for type II methanotroph PLFAs in the sedimentary (−861‰) and granite (−867‰) waters were very similar to the Δ14C values of dissolved inorganic carbon (DIC) in each water (∼−850‰). This suggests that type II methanotrophs ultimately derive all their carbon from inorganic sources, whether directly from DIC and/or from CH4 produced by the reduction of DIC. In contrast, δ13C values of type II PLFAs in the sedimentary (−93‰) and granite (−60‰) waters indicate that these organisms use different carbon assimilation schemes in each environment despite very similar δ13CCH4">δ13CCH4 values (∼−95‰) for each water.

    Full Text Available Desde hace más de treinta años, la inserción quirúrgica de puentes aorto-coronarios autólogos de vena safena y de arteria mamaria, constituye el tratamiento de elección para pacientes con enfermedad coronaria severa. La vida útil de estos injertos ha demostrado ser mayor en los colgajos de tipo arterial, aunque su uso está limitado por la restringida disponibilidad de los mismos. Por esta razón, y a pesar de que tienen mayor riesgo de presentar oclusión, los injertos de vena safena son los que más se usan en estos procedimientos de reperfusión miocárdica. Aún no se han esclarecido del todo las razones por las cuales los injertos venosos se ocluyen luego de su inserción en los lechos arteriales; no obstante, se ha propuesto que podría deberse a diferentes factores como: trauma mecánico quirúrgico, aumento de la presión arterial y disminuido estrés de fricción. En 1996 se describió la técnica "no-touch" de preparación de los injertos venosos, en la cual se implantaron los puentes venosos en los lechos coronarios junto con el tejido peri-vascular que los circunda, y demostró mejorar la vida útil de este tipo de injertos. Recientemente se ha propuesto que el tejido adiposo peri-vascular podría desempeñar un papel en la regulación del tono vascular, e incluso se ha descrito la existencia de un factor relajante derivado del adipocito (ADRF, cuya naturaleza no se ha esclarecido completamente. El objetivo de este articulo es revisar los diferentes factores vinculados con la oclusión de los injertos aorto-coronarios, las posibles vías fisiopatológicas que configuran este fenómeno, las nuevas alternativas quirúrgicas utilizadas para la preparación de los injertos venosos y los avances en la descripción del ADRF y su papel en la regulación del tono vascular.Since more than thirty years, surgical insertion of autologous aortocoronary bypasses from saphenous vein and mammary artery constitute the election treatment for

    2001-02-01

    Geostatistical simulation is used to extrapolate data derived from site characterization activities at the MIU site into information describing the three-dimensional distribution of hydraulic conductivity at the site and the uncertainty in the estimates of hydraulic conductivity. This process is demonstrated for six different data sets representing incrementally increasing amounts of characterization data. Short horizontal ranges characterize the spatial variability of both the rock types (facies) and the hydraulic conductivity measurements. For each of the six data sets, 50 geostatistical realizations of the facies and 50 realizations of the hydraulic conductivity are combined to produce 50 final realizations of the hydraulic conductivity distribution. Analysis of these final realizations indicates that the mean hydraulic conductivity value increases with the addition of site characterization data. The average hydraulic conductivity as a function of elevation changes from a uniform profile to a profile showing relatively high hydraulic conductivity values near the top and bottom of the simulation domain. Three-dimensional uncertainty maps show the highest amount of uncertainty in the hydraulic conductivity distribution near the top and bottom of the model. These upper and lower areas of high uncertainty are interpreted to be due to the unconformity at the top of the granitic rocks and the Tsukyoshi fault respectively.

    Rock stress measurements have been performed at the MIU (Mizunami Underground Laboratory) site to understand in - situ stress states. The hydraulic fracturing method has been applied in 1,000 m - deep boreholes. The results show that the stress state varied with depth from reverse fault type to strike - slip fault type. The ratio of maximum and minimum horizontal stresses is about two and is independent of depth. The orientation of maximum horizontal stress deeper than 200 m - 250 m coincides with the direction of the regional stress state. (author)

    The recently developed noncontact tonopachymeter Tonopachy NT-530 P provides intraocular pressure values corrected for central corneal thickness (CCT). The purpose of this study was to assess the accuracy and repeatability of its CCT measurements. The CCT measurements were obtained in 64 right eyes of 64 young healthy subjects using the Orbscan corneal topography system followed by the Tonopachy and then by ultrasound pachymetry (UP). Another sample of 31 subjects was used to test the repeatability of the tonopachy measurements in 2 separate sessions 1 week apart. To compare the tonometers and determine intersession repeatability for the tonopachymeter, differences in the readings provided by pairs of the instruments or obtained in the two sessions were plotted against mean differences. The hypothesis of zero bias was examined by a paired t-test. The coefficient of repeatability was calculated as the 95% limits of agreement (LoAs) of differences between the 2 sessions. Measurements made using the three instruments were significantly correlated (P<0.001). Mean CCTs (±SD) measured using the Tonopachy, Orbscan (acoustic factor set at 0.92) and ultrasound pachymeter were 530.42 ± 34.96, 526.73 ± 39.53, and 550.69 ± 37.26 μm, respectively. The differences between modalities (±95% LoAs) were -3.68 ± 24.36 for Orbscan versus Tonopachy, 20.66 ± 14.69 for UP versus Tonopachy, and 23.95 ± 24.21 for UP versus Orbscan. The coefficient of repeatability for the tonopachymeter was ±15.11 μm. The Tonopachy offers similar CCT measurements to those provided by conventional pachymeters with good repeatability.

    In order to understand the groundwater flow deep underground and its long term evolution in the future, it is necessary to develop a comprehensive hydrological evaluation system including in-situ investigation methodology, instrumentation for measurement and an assessment method such as numerical simulation. A hydrological evaluation system was developed and a project was planned to confirm the efficiency of the system. The project, named the Shaft Excavation Effect Project, in which a shaft 6 m in diameter and 150 m in depth was excavated and the system was applied to evaluate the shaft excavation effect on groundwater flow. The following results were obtained. 1. The recharge rate from the unconsolidated formation into the rock mass underneath was calculated to be 0.57 mm day 2. The hydrogeological model was classified into 12 groups according to the results from a geological survey, geophysical logging and in-situ hydraulic tests. 3. The predictive simulation and the subsequent observation showed good agreement, namely: the area where pore water pressure was considerably influenced by the excavation was within a range of 100 m around the shaft; the inflow into the pre-existing shaft and the drift was not affected by the excavation of the new shaft. 4. The efficiency of the hydrological evaluation system has been confirmed.

    Physical and chemical properties of polychlorinated naphthalenes are reviewed in the aspect of the reaction pathway of formation concerning polychlorinated dibenzo-p-dioxin (PCDDs) and polychlorinated dibenzofurans (PCDFs). PCNs are composed of the same number of isomers and a few of them are considered to have similar toxicity with PCDDs and PCDFs. The procedure for isomer specific analysis was developed to clarify the relation between the formation pathway and isomer composition. The contribution of each pathway will be studied in future by comparing the composition of PCDDs, PCDFs and PCNs. (author)

    In the flowing fluid electric conductivity (FEC) logging method, well bore fluid is replaced with deionized water, following which FEC profiles in the well bore are measured at a series of times while the well is pumped at a constant rate. Locations where fluid enters the well bore show peaks in the FEC logs, which are analyzed to infer inflow strengths and salinities of permeable features intersected by the borehole. In multirate flowing FEC logging, the flowing FEC logging method is repeated using two or more pumping rates. The results, coupled with those of a conventional well test over the entire borehole, enable the transmissivities and inherent pressure heads of permeable features to be determined. Multirate FEC logging is carried out on a deep borehole in fractured granitic rock using three different pumping rates. Results identify 19 hydraulically conducting fractures and indicate that transmissivity, pressure head, and salinity vary significantly among them. Using three pumping rates rather than the minimum number of two permits an internal consistency check on the analysis that provides a measure of the uncertainty of the results. Good comparisons against static FEC profiles and against independent chemical, geological, and hydrogeological data have further enhanced confidence in the results of the multirate flowing FEC logging method.

    102 patients with sub-clinical intra ductal non invasive breast cancer (T0N0) treated by limited surgery and curative radiation therapy. Follow-up ranged from 2 to 10 years with a median follow-up of 59 months. The long term survival rate of this therapeutic approach, consisting of simple excision without any adjuvant treatment and radical mastectomy was close to 100%. The actuarial local recurrence rate was only 8.6% at 10 years (confidence interval: 4.6 to 12.6%), which strongly suggests that radiation therapy is active on multicentric foci. Salvage surgery could be performed in every case of local recurrence. The survival rate of in situ breast cancer (T0N0) treated by conservative radio-surgery is comparable to that of radical mastectomy, while cosmetic results and psychological impact appear to be better for the conservative technique (breast preservation rate = 91 to 96%).

    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.

    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

    In the production of steel including high oxygen quantityt and special steels, tiny amounts of boron are added in steel melts for increasing hardness of the center of steels. But in that case, the furance consisting of refractory with high corrosion resistance tends to be damaged. In order to elucidate this problem, the refractory materials were examined by observations after real operating and reactions between presumed B{sub 2}O{sub 3} formed by boron oxidation and main ceramics constituting the refractory was investigated. In the production of steels including high oxygen quantity, both magnesia spinel and alumina-zirconia-carbon with non-silica were damaged and caused melt flow stopping. Therefoe reactions between presumed reaction products of B{sub 2}O{sub 3} and four kinds of bricks made from oxide ceramics which constitute the refractory, was examined. B{sub 2}O{sub 3} powders were put in hole of bricks and bricks were heated to 1500 degree C for one hour in argon. As the result of these experiments, the reaction between ZrO{sub 2} bricks and B{sub 2}O{sub 3} powders was not found. The practical test was done based on this result installing rings from zirconia materials inside pores of SG-P made from alumina-zirconia-carbon materials. This resut showed that damage due to melted steel was slight. (NEDO)

    The author had doubt about the method of designing controller system baste degraded models converted from physical models by using differential approximation when he considered controller of temperature distribution in 1984. He considered that controlling models could be use without accuracy degradation of physical models at least. He knew that Laplace transform and Fourier transform and so on are integral transformers, and that transformers being finite integral range were finite integral transformers. After that, adopting finite integral transformers to the control problem of axial temperature distribution in absorbing tower having migration layers, and agreeing prediction by simulation with results of experiments, he came to think control of distribution constant system in earnest as a theme of research. Especially, optimum arrangement problem of sensors and operating ends being characteristic problems in control of distribution constant system could be modeled and solved simply by performing this approach.

    Change in physical properties of granite is strongly affected by brittle deformation. Fractures are the main flow paths for the migration of contaminant materials and change in hydraulic properties of rock mass. Anisotropy of pore structure and permeability were studied using drill core of Toki Granite affected by a reverse fault -Tsukiyoshi Fault Zone (TFZ). The effect of deformation due to faulting is primarily observed on the micro-crack development.Based on fracture frequency distributions logged in the borehole, representative samples of variably deformed granite were selected to show the change in deformation and the control of structures on porosity, pore structure and permeability with depth toward the TFZ. Two fault zones were recognized in the borehole by examination of core and detailed structural analysis using BTV data. Movement indicators (mineral lineations) along fault planes and overall fracture orientations are consistent with regional structures. XRD analysis indicates hydrothermal activities along fault zones. Porosity of granite range from 0.54% to over 5.42%. The pore structure was visualized by a method assisted by a Laser Scanning Confocal Microscope where 3D images of pore structure were reconstructed from impregnated coupons. Micro-cracks were mainly observed at grain boundaries, cutting feldspars and biotite crystals in fresh granite and fracture zone. In the fault zone where the deformation is characterized by grain size reduction, the resin is seen to fill the fault matrix in a diffuse pattern. Crack density increases toward the fault zone where the cracks are highly oriented parallel to the TFZ.Permeability measurements were performed by a High Pressure-Temperature gas apparatus. In this method pore oscillation is applied with nitrogen gas as a pore fluid. Confining pressure was increased and then decreased in the range of 10-200MPa.The pore pressure was kept constant at 20MPa during oscillation method for Pc higher than 30MPa.Preliminary results indicate permeability of fresh granite about 10-15m2 at the initial confining pressure is higher than the fractured sample with chlorite veins of 10-18m2.Permeability of gouge in proximity to the Tsukiyoshi Fault core is 10-13m2. Result on permeability from two different directions show a decrease in permeability by a factor of one to two orders of magnitude in direction parallel to the TFZ.

    By the high exposure of the TCDD, it was confirmed that the death by the cancer remarkably increased in the research for the chemical plant worker. The exposure response analysis was carried out on 3500 workers of the factory with Kyle Steenland and cooperative research people who were the epidemiology researcher of National Institute for Occupational Safety and Health producing the chemicals including the TCDD, in U.S.A. As the result, the cancer mortality rate increased it in the average at 13%, and 60% was increased on the whistle blower who the TCDD was especially high. In our analysis, of the fact of which cancer, the high exposure of the TCDD has specially been connected with the superfluous crisis of all cancers. However, the crisis of the superfluous cancer is described whistle blower high, and this high exposure is called being an exposure of the concentration which is near for TCDD level used for the animal experiment at usual 100-1000 times.

    In the combined system of polymer additives and riblets, the polymer additives expand the range of non-dimensionalized riblet width s{sup +} where the riblets reduce the frictional drag. Although in the higher region of s{sup +} the riblets increase the frictional drag as the rough surface, the polymer additives thicken the wall layer, which dumps the drag increase due to riblets and then gives the benefical combined effect in this higher region of s{sup +}. Based on this scinario, the velocity profile and the pipe frictional coefficient for the combined system were derived from the velocity profile of each system. The turbulent velocity profiles were measured for the combined system using a laser Doppler velocimetry. The measured results agreed well with the derived prediction for the combined system.

    The paper described the flow of the standardization for EV use charge system and the inter-control with vehicles. Charge systems now used on the market are the inductive charge system and conductive charge system. The inductive charge system has no mechanical touches and is excellent in durability because the electromagnetic induction is used to the portion of power transmission. As to the standardization of the inductive charge system, it was found out that the construction of the world standards in the electric-wave use system is difficult, and the optical communication system was studied. At present, the work for revision has been proceeded with of the standards for the charge paddle (optical communication interface is adopted) which was reduced in size by about 40% of the conventional one. This charge paddle was made public at EVS15 in September 1998, and is being developed jointly with GM-Toyota. Around November 1999, the standards are expected to be formally revised. For the power control of the charger, the controller on the vehicle side transmits power request values. The rise in power request value is limited, so that the rapid power increase is avoided.

    For high-caking Warkworth and low-caking K-Prima coals, Geiseler plastometry, differential scanning calorimetry (DSC), proton magnetic resonance thermal analysis (PMRTA) and dynamic viscoelasticity were measured at a heating rate of 3 degree C/min under nitrogen. The amount of solvent-soluble constituent of the coals heat-treated at 3 degree C/min was also measured by using a solvent extraction with carbon disulfide-N-methyl-2-pyrrolidinone mixed solvent at room temperature, which gives high extraction yields for the heat-treated coals in the softening range. Changes in various chemical and physical parameters from the measurements were compared with one another to investigate the mechanism of softening and fusibility of coals. We suggest that the softening is occurred by a physical relaxation of aggregates in coal macromolecular structure and the amount of the solvent-soluble constituents greatly increases, resulting in enhancing the softening and fusibility. The mobility parameter from PMRTA, the viscoelastic parameter and Geiseler fluidity gave the maximum at similar temperature. showing that fusibility is the result of increased mobility of whole coal. The dynamic viscoelastic measurement was found to be a useful and convenient means for the study on caking behaviors of coals, since it can estimate concurrently both the fluidity and the elasticity of coals.

The heat transfer coefficient between a vertically immersed heater and bed in a pulsated fluidized bed is measured under various pulse cycles and fluidized particles. The obtained results are compared with those in a normal fluidized bed with continuous fluidization air injection. The relation between heat transfer coefficient and bubble characteristics, evaluated by using a digital video camera, was investigated. For certain fluidized particles and operated pulse cycles, fluidization of particles and increment of heat transfer coefficient can be obtained under lower mean air velocity based on a pulse cycle duration than minimum fluidization air velocity of the normal fluidized bed. Under the pulse cycles where a static ed is formed in off-period duration, the improved heat transfer rate in contrast with the normal fluidized bed can be measured. This because of the large bubbles formation. As the heat transfer in the pulsated fluidized bed is obstructed with increasing time to keep a static bed due to the excess of-period duration it is indicated that there is an optimum off-period duration based on the heat transfer rate.

    The effect of added water on structural change in castor oil was studied by a hot wire method. The change in kinematic-viscosity coefficients for anhydrous and hydrous castor oil were measured to evaluate the interaction between water and castor oil molecules. The kinematic-viscosity coefficient gradually increases with increasing the water content and reaches the maximum value at 4075 ppm of water. However, with the further increase in water, the kinematic-viscosity coefficient sharply decreases due to the destruction in the liquid structure of castor oil. Eventually, the maximum value is attained at the solubility limit of water in oil. The ratio of the number of hydroxy groups of glycerol triricinoleate in the castor oil to the amount of water molecule is 5/mol H{sub 2}O at the maximum kinematic-viscosity coefficient, where the liquid structure is developed due to the intermolecular crosslinking of water. However, the crosslinking of water disappears at the solubility limit of water and a water cluster is formed. In this case, water acts as a kind of a plasticizer decreases the kinematic-viscosity coefficient. The liquid structure is gradually destroyed at each water content with the rise in temperature from 10 to 50 degree C and it almost disappears at 60 degree C. (author)

    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)

    The discharge coefficients of the sonic Venturi nozzle were measured for eleven gases on the Reynolds number range from 2 x 10{sup 3} to 4 x 10{sup 4}. The results showed that the discharge coefficients strongly depend on gases. And it was also suggested that the discharge coefficients of most of the gases tested can be described by using two parameters theoretically determined on the assumption of isentropic flow of ideal gas, if they are on the conditions which are not so far from the ideal gas state. The differences between the theoretical and the experimental discharge coefficients were within 0.5 percent, except for CO{sub 2}, SF{sub 6} and C{sub 3}H{sub 8}. (author)

    The effect of the surface roughness on the contact charging of polypropylene with mercury has been studied by measuring the two-dimensional surface charge distribution. For each sample film, one half of its area was made rough by sandpaper, and the other half was left untreated. These two portions were charged by contacting them simultaneously with mercury, and the two-dimensional surface charge distribution was measured over the entire sample. Our observations show that the behavior of the contact charging clearly depends on physical roughness. The charge density on rough surface was lower than that on smooth surface. Moreover, when the surface was made exceedingly rough, no contact charging occurred. (author)

    Corrosion resistance of diffusion bonded joint with Ta foil inserted between the bonded surfaces and friction welding joint for SUS304L and Zr was examined in 3N-HNO{sub 3} solution contained Cr{sup 6+} ion. In a short term dipping test, it was difficult to qualitatively investigate the corrosion property for both joints, because it depended strongly on the surface condition (preparation) of the specimen before the test. In a long term dipping test, however, the type of the corrosion was mainly found intergranular corrosion in SUS304L base metal for all of the joints, moreover this developed the falling off the crystal grain of SUS304L base metal. In this corrosion process, a possibility that galvanic potential difference between dissimilar metals accelerated corrosion was pointed out, then local potential gradient was investigated using a measuring system, in which a sharp vibrating probe was scanned across the joint interface. SUS304L base metal showed a positive local potential gradient which indicated on acceleration of corrosion in SUS304L. But it was not so large and corrosion rates of SUS304L for the both solid state joining were nearly same value as that without Zr or Ta base metals. The acceleration of the corrosion at dissimilar metal joints were not observed from the results of the dipping test and the measurement of the local potential gradient, it is considered that there is no problem of the corrosion resistance in these joints.

    Ln-Cu/Al{sub 2}O{sub 3}, Ln-Fe/SiO{sub 2}, Ln-Ni/SiO{sub 2}, Ln-Co/SiO{sub 2} bimetallic catalyst are obtained Cu/Al{sub 2}O{sub 3}, Fe/SiO{sub 2} and Ni/SiO{sub 2} and Co/SiO{sub 2}, when it reacted with the rare metal which dissolved in the liquid ammonia. Using it, the reaction between carbonyl compound and ammonia was examined at 473-523K reaction temperature. In the reaction between carbonyl compound and ammonia, these bimetallic catalysts can be developed to amination and reductive alkylation, those relation reactions and in order to show the activity for hydrogenation, dehydrogenation and conversion hydrogenation, which made the ammonia to be the hydrogen source. The catalysis greatly changed with the rare earth metal composition in the catalyst. Especially, the Ln-Cu/Al{sub 2}O{sub 3} catalyst showed the activity for the reaction between methyl acetate and ammonia. By adding the rare earth metal at Cu/Al{sub 2}O{sub 3}, the Eu-Cu/Al{sub 2}O{sub 3} catalyst was more activated, and the acetonitrile was given. Eu-Cu /Al{sub 2}O{sub 3}, since it has the high activity for the conversion hydrogenation from the ammonia, the reductive amination progressed acetone ammonia hydrogen, and isopropylamine was formed.

    This paper introduces one example of research relating to the corrosion of sprayed coating at the Institute. The research has been conducted, in the environment of a frozen water solution, on the corrosion characteristic of aluminum-zinc thermally sprayed coating which is applied to the anti-corrosion of an aluminum and steel base material. The purpose is the protection against corrosion of the base material by dissolving this coating. Regardless of the sprayed coating, the characteristic of the surface-covered coating is very similar to that of electroplating. As a result of the examination of the corrosion characteristic of WC/Co based sprayed coating, corrosion resistance was found to be improved by adding Cr to the binder of Co. In the acid environment, WC/Co seems to be effective for corrosion resistance. Using the method of cladding by plasma powder spraying, a surfing layer of an Ni-Cr alloy was made on the surface of a carbon steel, with carbide particles dispersed, thereby examining corrosion resistance, wear resistance and high temperature oxidation characteristic. The cladding by welding of the Ni-Cr alloy was performed before carbide was dispersed, suppressing the dilution of Fe from the base material, which revealed great improvement in corrosion resistance and high temperature oxidation.

    In order to interpret resistivity profiles derived from electrical and electromagnetic surveys, it is necessary to study the correlation between electrical resistivity of rock and engineering properties. In this paper, we investigate the electrical resistivity of rock and its correlation to engineering properties. The experiments reveal the importance of electric surface conduction for studying those problems. These results suggest that resistivity measurements can be used as a quantitative guide in evaluating an area as to its engineering properties. (author)

    Lifting phenomena caused by vortex-flame interactions have been investigated about diluted propane jet diffusion flames forced by a speaker installed at the bottom of a fuel tube. Open let diffusion flames were formed on a co-flow burner composed of the inner fuel tube and an outer air tube. Two type nozzles of rim thickness of 1mm and 0.2mm were set at the end of the fuel tube for each experiment and the effects of the rim thickness on the flame stability were investigated. Artificial vortices were imposed in the fuel flow through the speaker excitation to make clear vortex flame interactions. The schlieren and OH radical imaging techniques were employed to unveil the interactions. Experiments in terms of the difference of rim thickness revealed that the ratio of the rim thickness to the Quenching distance is important for lifting criteria as proposed by Takahashi and Schmoll, because the ratio of unity determines the limitation of whether the end of the flame base being in or out the recirculation zone behind the rim. Moreover, it revealed that the vortex-flame interactions are able to become the trigger of lifting, though the effect to lifting was questionable so far. (author)

    The power loss (P{sub cv}) in Ni-Zn ferrite was analyzed by combining two methods. That is, P{sub cv} was divided into hysteresis loss (P{sub h}) and residual loss (Pr) from the frequency dependence of the power loss according to the method of Otsuki et al., as a first approach, and also the loss factors attributed to domain wall motion (P{sub w}) and the rotation magnetization (P{sub rot}) by adapting the method proposed by Visser et al. as the other one. The hysteresis loss dominates P{sub cv} in the frequency range below 500kHz, while Pr becomes predominant factor in the higher frequency range more than 500kHz. On the other hand, P{sub w} dominates P{sub cv} in the measured frequency range. It was found, by comparing the loss factors obtained by the analyzing methods, that Pr is mainly attributed to the domain wall motion in the lower frequency range and to the both magnetization processes in the megahertz range. It was also found that P{sub w} consists of P{sub h} and another loss factor which can be attributed to the dynamic motion of the domain wall. (author)

    An FTTC (fiber to the curb)-assisted optical/coaxial network for general clients and a multi-purpose use demonstration test system for the transmission line are constructed, and a performance verification test is conducted. For the testing, a common transmission line installed in the service area of Keihan Cable Television, Hirakata City, is utilized, and the test system consists of a landline system utilizing a CATV drop line and a wireless system. Remote meter-reading, load survey data collection, power consumption notification, and Internet service are provided for a total of approximately 100 clients engaged in monitoring via landline or wireless channel. During the test, ingress noise after uplink from the room to the transmission line is measured, quality verification is performed in relation to the state of data communication, etc., and it is found that communication services such as data collection and information delivery are executed practically with no difficulties on both landline and wireless systems. A client who carefully watches the load curve enjoys a consumption reduction effect of approximately 0.3kW at the maximum over a client who does not. (NEDO)

    With a purpose of attesting preferential oxidation of an alloying element which has low solid solubility in aluminum, an Al-5at%Y alloy was mechanically alloyed with or without addition of metal oxides. Y was chosen as an alloying element since it has higher oxidation tendency than Al and a low maximum solid solubility of 0.17mass% in Al. Mechanically alloyed powders were consolidated by hot-extrusion to the P/M materials of which constituent phases, microstructures and mechanical properties were examined. The added oxygen, either from the process control agent or from oxide powders, acted as oxygen sources for internal oxidation, and Y in Al was shown to be preferentially oxidized to Y{sub 2}O{sub 3} and Al{sub 5}Y{sub 3}O{sub 12}. The P/M materials with addition of oxide powders showed high tensile strength of about 600MPa at room temperature. (author)

    Synthesis of nano-scale inorganic particles and development of the application to electronics, photonics and catalytic reactions are recently paid attention. Nguyen, Mirkin et al. recently reported a simple method for synthesizing a nano organic-inorganic composite particle by polymerizing a monomer on the surface of a gold particle. The polymerization employs ring-opening metathesis polymerization of norbornene ring, and the point is using a Ru catalyst that makes living polymerization possible. In addition, Weiss, Grubbs et al. used the same method to grow a homopolymer of the similar norbornene monomer on the gold surface, and directly observed the existence of a polymer chain with a length of several hundred A or greater on the gold surface with an interatomic force microscope, a scanning tunnel microscope and scanning electron microscope. The reactions used in these cases is considered to be easily adapted to other monomers having a norbornene ring. This method is regarded as an effective method for forming a copolymer or a homopolymer having a uniform length on metal particles. (NEDO)

In order to investigate the facts, a group of experiments are planned, and the measured waves are compared with the simulation waves of one experiment. The results are as follows. (1) It seems that S pole and N pole are apart from the ends of a magnet. (2) These poles may movable on the magnet due to the influences of another magnet. (3) While another magnet exists between a sensor and an objective magnet, the recording obtained by moving the sensor may largely differ from the recording obtained by moving the objective magnet.

    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.

    When industrial robots are made to recognize obstacles or to collide with them, their speed of recognition is a very important problem. This article proposes a method to avoid obstacles using a disturbance observer which detects obstacles and its collision singnal. For the detection of collision with obstacles in this method, the reaction and the inertia force cause by self-inertia variations are utilized among the disturbance components obtained from the distrubance observer. Since this method is different from torque or tactile sensors, information about the torque current and the rotation speed of the motor are enough for this method, and it is unnecessary to consider especially the installation place of the sensor. It is also possible to detect collision at every part of the robot by using this method. The effectiveness of this method was verified by the experiment conducted to avoid collision by an articulated robot with three degrees of freedom. It is especially effective in the application to the repeating motion in which the characteristics of the disturbance along its trajectory can be known beforehand. 7 refs., 14 figs., 1 tab.

The campaigns of advertising used innovatives strategies to associate consume with modernity, both of mechanization as the aspirations of transformation to approach european models of its time. This advertising also make its part in the development of a female worker imaginary, wich shows the tension between the traditional moral values of constrained woman to domestic activities and dependent of the family nucleus and the patriarchal hierarchy, and the dawn of the female worker with economic independence and hints of individuality in her moral decisions. This paper analyze fragments of these advertising stories related with social values of the city at begin of XX century.

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.

    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.

    Full Text Available Based on the computer processing of the 16th century grammarians, we have analyzed the definitions of phones and the relationships between these and synchronic and diachronic facts, which are also defined; the forms of the words that have been selected as the object to bee described or as the illustration of the described facts are compared with the forms of the same words employed in non metalinguistic uses. The raising of atonic being the only point that is undisputed in this matter (this is due to the clearness of the description of the first grammarian, Fernão d’Oliveira, this information enables us to test the reliability of the other testimonies. The raising of the remaining atonic vowels continues to be a subject of debate, and it presents us with a vast area of common questions, starting with the chronology. The contribution of Fernão d’Oliveira being the most important, we have analysed the basic concepts («letter», [vowel] «pequena» = small, «grande» = big; we have defined the dominant perspective as being that of writing; we have revealed a larger incidence of descriptions in the phones represented by and , and , in accordance with theaffirmations of proximity between them, and we have observed contrasts between the expressed doctrine and information conveyed by testimonywords, as well as between the praised writings and the genuine writings of the Author. The lack of an adjusted terminology, which is still evident in Soares Barbosa (1822 is reflected in the difficulties in conceptualization, also clear in the other Authors, whose complementary information we have synthesised. The variation ~ and ~ give rise to a large number of references; the interpretations and connections are not always appropriate, but this does not make them less informative, at least when they are compared with changes by assimilation, dissimilation and analogy, whether theses changes occurred in the past or are still in progress at that time. As a whole, the exploration of the descriptions leads partly to the characterization, in the plane of the atonic vowels, of the state of the language on which the movement of relatinisation will spread.

    We inspect the influence of position-dependent effective mass (PDEM) on the third-order nonlinear optical susceptibility (TONOS) of impurity doped quantum dots (QDs) in the presence and absence of noise. The TONOS profiles have been followed as a function of incident photon energy for different values of PDEM. Using PDEM the said profile considerably deviates from that of fixed effective mass (FEM). However, a switch from one mode of application of noise to another primarily alters the TONOS peak intensity. The observations highlight the possibility of tuning the TONOS profiles of doped QD systems exploiting noise and PDEM.

    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.

    The behavior of Izod impact strength of acrylonitrile-butadiene-styrene (ABS) resins with the addition of silicone fluid has been investigated using some graft structure. Poly (dimethylsiloxane) was sued as silicone fluid, and added to the resins in the range of 0 to 0.1 wt%. In the case of lower graft density, Izod impact strength was almost the same as that observed in the absence of silicone fluid, though, the effect of added silicone fluid was marked in the case of higher graft density. Therefore, it was suggested that silicone fluid exists at near the rudder phase and gives a significant effect to the initiation of craze by contributiong to the entanglement of graft phase and matrix phase.

    The surface charge distribution of polypropylene with spherulites was investigated using charged sub-micron solid particles after the surface was charged by contact with mercury. The charge polarity of the sample surface after contact was negative and that of solid particles was positive. We observed that many particles accumulated in the interface region between spherulites as well as that between spherulites and outer non-spherulitic region, and also in the non-spherulitic region. These results can be explained by means of distribution of electron traps. (author)

    A regional new energy vision was formulated for Imabari City for reducing its oil dependence proportion, properly dealing with global environment matters, reenergizing the region, and for improving the impression that the region gives. The city in fiscal 1998 demanded 408 times 10{sup 10} kcal of energy, including 75% in oil and 9% in electricity. As for new energy availability, it was estimated that 625 GWh/year would be obtained from photovoltaic power generation, 26.5 GWh/year from ocean energy, 10.9 GWh/year from refuse-fueled power generation, 3162 Tcal/year from solar heat utilization, 98.8 Tcal/year from refuse-derived fuel, 28.2 Tcal/year from refuse-derived heat utilization, and so forth. New energy introduction projects were discussed, which included the introduction of photovoltaic power generation into training and educating facilities including schools, city office buildings, welfare facilities, hospitals, water purification plants, sewage treatment plants, city-managed housing, public gardens, lighting devices for disaster prevention, and into single-family housing; introduction of solar heat utilization and natural gas cogeneration into public hospitals, welfare facilities, and heated swimming pools; and the introduction of refuse-fueled power generation and natural gas-powered automobiles.

    A flow regime map for a two-dimensional spouted bed is constructed from the experimental conditions that cause the fixed bed, spouted bed, bubbling fluidized bed and slugging bed. The map is compared to the one that is made from the simulations using P-TAK, a general-purpose simulation code of gas and particle flow by the discrete element method. Both maps coincide very well, indicating that the discrete element method has big potential for predicting critical flow conditions such as the minimum spouting velocity or the maximum spoutable bed height.

    The reaction of trimethylenemethane with various alkyl-substituted p-benzoquinones was investigated. The reaction of 2,5-di-tert-butyl-p-benzoquinone with 2-(trimethylsilylmethyl) allyl acetate (1) was conducted with palladium (0) as a catalyst to afford 1 : 1-C=C-cycloadduct 2 in good yield. Similarly, 1 : -C=C-cycloadducts 3, 4, 5 and 6 were obtained with 2,6-di-tert-butyl-p-benzoquinone, 2,3,5,6-tetramethyl-p-benzoquinone, 2,3,5-trimethyl-p-benzoquinone and 2-methyl-1,4-naphthoquinone, respectively. On the other hand, the reaction with methyl-p-benzoquinone afforded the complicated mixture. As is the case with Diels-Alder reactions, the cycloaddition of trimethylenemethane with p-benzoquinones occurred towards C-C double bond. So, the reaction of trimethylenemethane with substituted p-benzoquinones is effective in the synthesis of methylenecyclopentane-fused cyclohexenediones having various substituents. (author)

    Industrially avaiable poly (bisphenol A arenedicarboxylate) Npolyarylate) is conventionally produced by the omterfacial condensation polymerization of bisphenol A and the mixture of terephthaloyl/isophthaloyl chlorides. We now report a new synthetic method without using the acid chloride derivatives, and the synthesis of oligomeric arenedicarboxylate by the melt condensation polymerization of bisphenol A and diphenyl terephthalte/isophthalate (mole ratio of reactants is 1/0.5/0.5). By removal of phenol from the reaction mixture, we obtained oligomeric ester, which can be changed to a high molecular weight polyester in the subsequent reactions. This report discussed the kenetics of the melt condensation of bisphenol A and diphenyl terephthalate/isophthalate mixtures. The melt condensation polymerization of bisphenol A and diphenyl terephthalate/isophthalate was analyzed by the bimolecular reaction of -OH and a phenyl ester. The activation energy was estimated to be 32.2 kcal/mol. The relationships between the reduced viscosity and molecular weight was estimated and the following experimental equation was obtained; {eta}{sub sp}/C=7.46x10{sup -5}M{sup 0.83}{sub w}. Polymer was analyzed by {sup 1}H-NMR, and the ratio of the end group of the hydroxy group to phenyl ester group was determined. FD-MS suggested four types of oligomeric ester end groups: phenyl-hydroxy, hydroxy-hydroxy, and cyclic. (author)

    With a purpose of attesting preferential oxidation of an alloying element which has low solid solubility in Al, an Al-5at%Ca alloy was mechanically alloyed with or without addition of metal oxides. Ca was chosen as an alloying element since it shows higher oxidation tendency than Al and a low maximum solid solubility below 0.01mass% in Al. Mechanically alloyed powders were consolidated by hot-extrusion to the P/M materials of which constituent phases, microstructures and mechanical properties were examined. The added oxygen, either from the process control agent or from oxide powders, acted as the oxygen sources for internal oxidation and Ca in Al was shown to be preferentially oxidized to CaO and CaAl{sub 4}O{sub 7}. The P/M materials with addition of CuO showed high tensile strength of above 500MPa at room temperature. (author)

    Three dimensional computations were performed using the KIVA-3 code to investigate the unsteady compressible turbulent flows about a practical train passing through a single-track tunnel. Both length of the train/tunnel and speed of the train were considered to investigate their effects on the train-tunnel interaction. In order to understand the whole process of the train-tunnel aerodynamic interaction, we studied the formation and propagation of the pressure waves, the reflection and radiation of the waves at the tunnel portals and the histories of aerodynamic forces on the train. The experimental results were compared well with the computational data. The code can be used to predict the aerodynamic phenomena of the train-tunnel system. (author)

    On the basis of data in previous reports regarding leaching experiments of water soluble vanadium compounds produced from dry mechanochemical treatment of EP dust by three kinds of ball mills, in the present research, the correlation between the yield of the vanadium compound and collision energy of balls instead of milling time was examined. The collision energy of ball in the three kinds of mills was simulated by particle element method taking into consideration the EP dust sample filling. As a result, the relationship between the yield and the collision energy was represented by one curve regardless of the kinds of the mills. This result suggests that the collision energy of the balls in the mills is one of the important factors dominating the dry mechanochemical reaction of EP dust. (translated by NEDO)

    The Solubility of triolein in supercritical carbon dioxide (SCCO{sub 2}) was measured by a continuous flow system at various temperatures (313, 323, 333 and 343 K) and pressures (15, 20 and 25 MPa). The solubility of triolein increases with experimental pressure. The obtained data were compared with previous investigations. At 15 MPa, the solubility is considerably governed by temperature (343-313 K), i. e. 10{sup 2} - fold change of solubility. On the other hand, at 25 MPa, which is fully mature supercritical conditions, the influence of temperature on the solubility become weaker. Under constant pressure conditions, solubility of triolein decreases gradually with increasing temperature. Solubility is correlated well with the estimated density according to Bender (1970).

    In many electromagnetic processings of molten metals, the interfacial motion between a molten metal and a slag plays an important role on the productivity and the quality of products. However the behavior of its motion has not been precisely examined yet because of technical difficulties in the direct observation of it. Here, a new experimental method has been developed to observe the interfacial motion between a liquid metal and a non-conductive transparent liquid. In the method, a laser slit beam which was rayed into the interface from the oblique upper side is so projected on a screen as to show the shape of the interface, which is recorded by a high-speed video camera. The interfacial motion caused by the imposition of a quasi-sinusoidal magnetic field is classified by use of the Shielding parameter R{sub {omega}} such that a periodical oscillation and an irregular motion dominate in the low frequency range (R{sub {omega}}<<1) and the high frequency range (R{sub {omega}}>>1), respectively and the periodical oscillation and the irregular motion coexist around the frequency range of R{sub {omega}} {approx} 1. It is noticed that the increase in viscosity of the liquid imitating a slag acted to suppress the interfacial motion and the wave number appeared larger in the case with the liquid imitating a slag than that in the case without it.

    The surface characteristics of surface-modified biocompatible ceramics made of {beta}-tricalcium phosphate (TCP) were found to change actively in tissue culture medium. Concentration changes of calcium and phosphate ions dissolved in distilled water or in culture medium showed that the solubility of the TCP ceramics was considerably high and depended on the pH value of the soaking medium. The most stable ceramics in the culture condition appeared to have the suitable surface for adhesion of L 929 cells. So, the solubility of the TCP ceramics as the cell carrier was considered to be the dominant factor in decreasing the adhesion of cells on TCP ceramics. Furthermore, it was found that the solubility and zeta potential of the surface-modified TCP ceramics, and cell adhesion and serum protein adsorption on the surface were varied with modification time.

    For many kinds of mixtures of pyrotechnic raw materials, the relation between mixture ratios with the highest or the maximum sensitivity in the electrostatic sensitivity test and those with the largest heat of reaction measured by the bomb calorimeter or calculated by REITP2 were discussed. The mixture ratios with the highest or the maximum sensitivity in the electrostatic sensitivity test coincided with those with the largest heat of reaction measured but did not coincide well with the calculated ones by REITP2. For many pyrotechnic materials, especialy for boron-oxidizer mixtures, the mixture ratios with the highest or the maximum sensitivity in the electrostatic sensitivity test were more fuel rich than those with the largest heat of reaction calculated by REITP2.

    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)

    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.

    The intermetallic compounds containing precious metals such as platinum white gold are widely used in chemistry or industry as catalysts. These alloy catalysts are mainly used in grinding the materials prepared by solidifying liquids. The authors of the paper attempt to prepare alloy powders of precious metal with Zr or Al by mechanical alloying (MA). As an object of applying them on a catalyst, alloy powders of precious metals (Pd and Pt) and M (Zr or Al) are regulated by the mechanical alloying reaction, and the results show that the Pd and Pt show different MA reaction while using Al as the M, the former generates an intermetallic compound as PdAl during the halfway point of the MA reaction, but the later generates amorphous powders. But, each of them generates amorphous alloys only while using Zr and the M. As a result of differential thermal analysis and electrical resistivity measurement investigating the crystalline process of the obtained amorphous alloys, it is clarified that the Pt-Al base alloy shows higher crystalline temperature compared with the other alloys. 8 refs., 6 figs.

    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.

    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 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.

    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 turtles was significantly lower (P 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.

    Ocular diseases reported in frogs include uveitis and glaucoma, which are associated with changes in intraocular pressure (IOP). The objectives of this study were to characterize the normal IOP for White's tree frogs ( Litoria caerulea ) using two types of rebound tonometers, and to assess whether time of day or method of restraint affected IOP. Eighteen conscious, unrestrained, ophthalmologically normal frogs were used to measure IOP using TonoVet® and TonoLab® tonometers, at three time points during the day. In a subset of 12 frogs, IOP was measured while under manual restraint using the TonoVet. Anesthesia was induced in 9 frogs using two different concentrations of MS-222 (0.5 g/L and 2 g/L) in order to evaluate for changes in IOP with the TonoVet. Mean (± SD) IOP values for the TonoLab (16.8 ± 3.9 mm Hg) were significantly higher than TonoVet values (14.7 ± 1.6 mm Hg; P frogs had significantly lower IOP (13.4 ± 1.5 mm Hg) compared with unrestrained frogs (15.3 ± 1.2 mm Hg; P frogs, but time of day and manual restraint can affect IOP values.

    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.

    Based on the author's precious numerical results of a reverse osmosis desalination system for seawater or brackish water utilizing the static pressure head of seawater in a deep-sea region or brackish water in a vertical pit, a dimensionless expression is formulated to predict the transmitted fresh water flow rate from the geometry and the submerged depth of the device, the pure water permeability and the solute permeability of membrane, and the physical properties of seawater or brackish water. The derived expression is compared with experimental results obtained by field experiments carried out in the Sea of Japan and the East China Sea with fair agreement and thus confirmed the applicability and usefulness of the expression.

    The ECO-OFFICE, applying technologies with low environmental burden, was built at the National Institute for Environmental Studies in 1995 to prove a reduction of CO{sub 2} emissions in the commercial sector could be achieved. We collected and analyzed operation data of the ECO-OFFICE from January 1996 to March 1998. We evaluated quantitatively the overall performance of the system and improved the system performance, based on these results. This paper is based upon data gathered from April 1997 to March 1998 about the energy consumption rate and the performance of a heat source system and a photovoltaic system. We evaluated the effect of improvements of the system by comparing its performance with that of the previous year. And we quantified the effect of introducing technologies with low environmental burden by converting the energy consumption rate and comparing it with that of an ordinary building. We specifically note that a system using photovoltaic cells was more energy efficient than one using solar thermal collectors in the air conditioning of the office building. (author)

    This paper discusses two main problems to develop practical inventory analysis using an input-output (I-O) table. The first is the allocation problem caused by use of an actual I-O table, which indicates transaction among sectors on monetary unit. When direct and indirect emissions at the production of commodities are calculated using conventional I-O analysis method, the values are underestimated or overestimated due to the assumption that a commodity is sold at a uniform price to all consumers. In this paper, modified method is presented, reflecting the fact that a commodity is sold at different prices to each consumer. It is found that CO{sub 2} emission factors of commodities estimated using the modified method are different fro those using the conventional method. The second is the way to combine process analysis with I-O analysis for reasonable and practical inventory analysis. The merit of process analysis is precise estimation reflecting actual processes. On the other hand, I-O analysis theoretically enables consistent estimation taking account of all processes in society. This paper describes an inventory analysis method that makes the best use of merits of both. CO{sub 2} emission factor of a boiler is calculated using the method and the result proves the method to be available. (author)

    A DSMC (direct simulation Monte Carlo) simulation using Dynamic Molecular Collision (DMC) model based on Molecular Dynamics (MD) calculation is applied for solving a two-dimensional non-equilibrium hypersonic rarefied flow over a flat plate with and without angle of leading edge. Numerical results show that non-equilibrium characteristics between translational and rotational temperature are obtained behind leading edge over the plate. The results of the DSMC agree well with those of the experiments, however, the results of the Navier-Stokes are quite different from those of the experiments. The comparison between Larsen-Borgnakke (LB) model and DMC model reveals that the DMC model obtains excellent results without a parameter such as an inelastic parameter. (author)

    A column/beam structure having reinforced concrete columns and steel beams (RC column/S beam structure) enables the assemblies to be manufactured in a plant by using PCa for the column including joints, and allows the assembling work at a job site to be performed by a dry/stacking construction method consisting mostly of the assembly operation. The writers developed a steel plate joint, a steel plate with an opening in the center, which is fixed inside a column by merely penetrating the joint with main reinforcements of the column, as a new joining method in the RC column/S beam construction that facilitates the PCa column. As a result of a previously implemented experiment of drawing out the joint, it was confirmed that the joint fixed by penetrating with the main reinforcements showed a sufficient fixing performance without special reinforcement, and that no damage was caused locally to the main reinforcements by drawing out the steel plate for example. In the subject research, for the purpose of grasping the basic dynamical properties of a bridge using the joint, a framework test was conducted on the six specimens with a reinforcing method varied for the joint. As a result of the test, the joint, having the opening in the center and penetration with the column main reinforcements, demonstrated a full fixing performance, ensuring a stable load/deformation relation up to a layer deforming angle of R={+-}25rad. In particular, no surface separation was recognized between the joint and the column concrete, and no local fall-off or the like of the joint was confirmed. (translated by NEDO)

    The dynamic mechanical properties of the composites of poly (p-phenylene terephthalamide) (PPTA) fibers (rigid molecules) and poly (methyl methacrylate) (PMMA) matrix (flexible molecules), were investigated as a function of the surface area of the fiber and temperature. These composites showed reinforcing effect indicated by the storage modulus (E') over the whole temperature range. At the temperature region of glassy state, E' was influenced by both the elastic modulus and the surface area of reinforcing fiber. However, at the temperature region of rubbery state, E' depended mainly on the surface area. Disappearance of {beta}-relaxation, that is attributed to rotation mode of the side-chain, and the shift of the higher temperature side of {alpha}-relaxation of main-chain of PMMA were observed in the PPTA composite with larger surface area. These results are attributed to an interaction at the PPTA/PMMA interface. Furthermore retardation of thermal decomposition of PMMA was observed in the presence of PPTA. It can be shown that the higher activation energy for the thermal decomposition of PMMA is equivalent to higher interaction energy in the PPTA composites. The shift of -NH, >C=O IR absorption band of benzanilide, a model compound of PPTA, with change in the PMMA composition proved that the interaction is chemically originated from the formation of hydrogen bond between PPTA and PMMA.

    We synthesized a novel cyclic formal, 1,3,5,7,10,13-hexaoxacyclopentadecane (HOCP), which is a direct reaction product of 1 mol of trioxane and 3 mol of ethylene oxide. The novel cyclic compound was separated and collected using a micro-distillation apparatus and gas chromatographic method. The chemical structure was determined using {sup 1}H-NMR, {sup 13}C-NMR, mass spectrum and elemental analyses. Formation of HOCP was critical. When the mole ratio of ethylene oxide to trioxane was below 0.026, only 1,3,5,7-tetraoxacyclononane (TOCN), which was the reaction product of 1 mol of trioxane and 1 mol of ethylene oxide was formed. When the mole ratio of ethylene oxide to trioxane was around 0.033, 1,3,5,7,10-pentaoxacyclododecane (POCD), which was the reaction product of 1 mol of trioxane and 2 mol of ethylene oxide was formed additionally to TOCN. When the mole ratio of ethylene oxide to trioxane was around 0.039, HOCP was formed additionally to TOCN and POCD. In the commercial base acetal copolymer which was produced by the copolymerization of trioxane and ethylene oxide, it is known that there is a consecutive three-unit sequences of ethylene oxide, and this consecutive sequences might be postulated to come from the ring-opening polymerization of the novel cyclic formal of HOCP. Direct reaction between trioxane and ethylene oxide is thought to supply us a possibility of a new type and new route of crown ether. (author)

    The writers have proposed a seismic retrofit technique using honeycomb dampers as a method for securing high safety with less reinforcing planes compared with conventional anti-earthquake reinforcements. As reported previously, in grasping the reinforcing effect of the two typical methods, a structural experiment was implemented using frame specimens through a scale-down to 1/2 size, confirming the effect for improving the bearing force of existing frames and the absorbing capacity of hysteresis energy, in the new reinforcing method of newly installing steel reinforcing frames with dampers. In this paper, possibility was investigated of simplifying a joining method in connection with the new technique, by carrying out an additional experiment which enabled the resulting effect to be grasped in the simplification of joining an existing part with steel reinforcing frames. In addition, a similar experiment was conducted on the new construction method using intermediate posts, on an assumption that an opening on both sides is secured inside a reinforcing retrofit plane, while a comparison was made with other methods in performance. As a result of the examination, concerning the method of newly installing vibration control frames, it became evident that these specimens with the joining method simplified can demonstrate a reinforcing effect comparable to the structural performance of the old specimens which used a conventional joining detail in anti-earthquake reinforcement. Concerning the balloon frame construction method, a fairly satisfactory reinforcing effect was also confirmed despite problems left on the details. (translated by NEDO)

    The authors proposed the snow cooling system of direct heat exchange between hot air and snow block with a vertical hole. In this snow cooling system, the characteristics of heat exchange is little affected by the amount of remaining snow, and the outlet air temperature is almost constant, and be enough low to use for the actual air conditioning system. So this system has become to be adopted widely. In this study, the authors investigated the effect of initial snow height on the characteristics of heat exchange by the experiment with models of practical scale. Experimental results showed that heat transfer coefficients on the snow surfaces of top and bottom plane were not affected by initial snow height, but the heat transfer coefficient of snow hole increased with decreasing snow height being affected by the entrance region. It was found that heat transfer coefficient of snow hole approached to a constant value on condition that snow height was over 2 meters. A empirical equation compensated by the initial height of snow block was obtained from the experimental results. (author)

    It is very important to use many kinds of natural energy resources to keep environment clean and to reduce the energy consumption. Many simple and skilful methods to utilize the natural energy have to be developed. The authors have been proposing to utilize snow stored till summer as one of the natural cold and clean energy resources. In this study, the authors investigated the characteristics of direct heat exchange between hot air and snow block with a vertical hole. This heat transfer model, so called as the snow cooling system, may he applied to various air-conditioning systems of conventional living room and so on. As the heat transfer process of this model is very complicated because the shape of the snow block changes by the progress of melting, the characteristics of -the direct heat exchange were investigated by the experiment with a model of practical scale. The outlet air temperature through the snow hole and snow melting process were measured for various air flow rates at constant inlet air temperature 30 degree C. Experimental results show that the outlet air temperature from the snow cooling system was almost constant and enough lower to use for the actual air conditioning situations. Heat transfer coefficients on the snow surfaces of top plane, bottom plane and side wall of the snow hole were clear by those experimental results, and the correlative equations between the overall Nusselt number and the Reynolds number are presented for three surfaces mentioned above.

    In Direct Internal Reforming Molten Carbonate Fuel Cells (DIR-MCFC) deterioration of catalytic activity takes place in the anode channel due to both the liquid-phase pollution and vapor-phase pollution. The liquid-phase pollution meant that catalytic activity is deteriorated by the molten salt's (62 Li{sub 2}CO{sub 3}/38 K{sub 2}CO{sub 3}) adhering to the catalyst. It can be solved by installing the protective barrier in the pollutant pathway. On the other band, the vapor-phase pollution meant that that catalytic activity is deteriorated by KOH adhering to the catalyst. Because the vapor-phase pollution is caused in the entire electrode, an effective defense method has not established yet. Moreover, a reactivation method of vapor-phase polluted catalyst has not been developed yet. In order to study the reactivation method, the adhesion form of potassium compounds in the polluted catalyst under the various gas conditions was evaluated by using a thermogravimetric analyzer in which water vapor can feed. Additionally, the activity of catalyst treated demonstratively was also tested by a differential reactor. As a result, KOH changes to K{sub 2}CO{sub 3} under the condition which CO{sub 2} concentration is larger than 25%. The catalyst with K{sub 2}CO{sub 3} cannot reactive. However., the activity of polluted catalyst is revived until 80% of initial activity by controlling the gas species concentration, especially for CO{sub 2}. Based on the results obtained by these fundamental experiments, the reactivation methods of polluted catalyst are proposed as follows; (1) Catalyst should load more in the upstream in the anode. (2) In order to reactive the polluted catalyst, the ratio of H{sub 2}O to CH{sub 4} in the fuel should increase, when DIR-MCFC is under operation. (3) Gas compositions under cell maintenance mode should be applied in the case that power generation quits. (author)

    Under the assumption of a large-capacity DC power transmission model project in the Far East and Siberia districts, technical study was made on the basic design of the project, considering selection of concrete power generation and consumption sites and power transmission routes, power transmission/transformation equipment, cables, and environmental impact. Study was also made on its applicability to similar projects in Japan. 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.

    For the purpose of promoting the introduction of new energy and enhancing the awareness of it in Mashiko Town, Tochigi Prefecture, an investigational study was conducted of the energy consumption amount of the city, existence amount of new energy and project for new energy introduction, and a vision was worked out. The FY 1999 energy consumption of the city was 69.80 x 10{sup 10} kcal in amount and was broken down into 49.6% of petroleum, 40.0% of electric power and 10.4% of LPG. As viewed by sector, the energy consumption consisted of 41.7% in the commercial/residential sector, 33.7% in the industrial sector and 24.6% in the transportation sector. As the project for new energy introduction, the following were studied: introduction of photovoltaic street light to the west promenade of the Nanai Station, introduction of clean energy vehicle to the Mashiko town office, introduction of photovoltaic power/wind power hybrid power generation facilities to the disaster prevention center, introduction of photovoltaic power generation facilities to the north sports grounds, supply of information on solar systems such as solar energy use water heater/heat storage tank/floor heating to the core facilities for lifelong study, education for new energy/environment to be given at elementary school/junior high school, etc. (NEDO)

We clarified theroles of BMP-2 and BMP-4, which are other members of BMPs, in cardiovascular formation at an early stage of embryo. In addition, we isolated a novel gene from bone mRNA and termed it rDLG-6. From the sequence comparisons by the BLASTX program, we found that rDLG 6 is a member of MAGUK (Membrane Associated Guanylate Kinase) family. (author)

    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.

    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)

    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.

    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)

    Described herein are the results of the experimental studies on combustion for mixed firing of waste (city garbage) and low-quality coal in external circulating fluidized bed (CFB) boiler for power generation, and the studies on high-efficiency mixed firing power generation system. The program for the basic research on the waste/coal mixed firing conducts thermal analysis of each sample type, to collect the basic data related to the burning profile from the ignition to completion of firing, and energy of activation, among others. The program for the flow characteristics of waste and coal in CFB conducts the experiments of the cold model. The program for the mixed firing with actual waste in the CFB pilot boiler conducts the mixed firing of low-quality coal of high ash content and high fuel ratio and actual waste (ash content: 60%, low heating value: 860kcal/kg), to confirm that the stable combustion is achieved at a mixed firing ratio of up to 40%. It is also found that the mixed firing produces smaller quantities of NOx, SO{sub 2} and CO emissions than the combustion of coal alone. The program for evaluation of the power generation system achieves a power generation efficiency of 28% at a mixed firing ratio of 22% with Chinese waste of low heating value and low-quality coal.

    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

    This study was undertaken to develop a method for evaluating geochemical environments in deep granitic basement rocks. The method involves analyzing fracture-filling minerals to determine their isotopic compositions. A preliminary isotopic investigation (δ 13 C, δ 18 O, 14 C activity) of the groundwater and fracture-filling calcite in granite at the Tono research site, central Japan, was conducted. The isotopic compositions were used, together with geological evidence for the history of the Tono area, to infer the origins of the waters from which the calcite precipitated. These waters were:1. hydrothermal solutions, 2. relatively 'old' fresh water, 3. seawater, and 4. present groundwater. The investigation methods were very valuable for evaluating the temporal variations of geochemical conditions deep underground. The isotopic evidence for seawater is so far the most direct evidence that seawater penetrated into the granite in this area in the past. (author)

    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.

    In search of measures to take for raising, developing and integrating venture firms, studies are made about the process and factors of growth after the corporatization of venture firms in the U.S. and Europe, and then about the mechanism of industrial integration in newly-arising high technology- and novel industry-intensive areas and the actualities of strategic clustering. In China, studies are made about feasibility of coordination with Japan. Activities are conducted in the four domains of (1) the analysis of development and growth factors after launching a venture firm in the U.S., (2) analysis of factors contributing to the development of industrial integration in newly-arising high-technology areas, (3) actualities of assistance to ventures in Europe, and (4) the survey of venture trends in China. In domain (4), venture firm creating, raising, and assisting conditions are studied. Also studied are the actual state of venture firm creating, raising, and assisting, and some cases of venture firm creation and raising. (NEDO)

  13. The Sustainability of Irrigation Schemes Under Climate Change

    Irrigation is considered to be one of the best practices in agriculture to ensure food security. However water resources that are used for Irrigation activities are increasingly coming under stress, either due to extraction or climate variability and change. To adequately plan and manage water resources so as to ensure their sustainability requires a long term investigations of streamflow and climate. Streamflow analysis and forecasting gives signal of the occurrence of floods and drought situations. However the ability to maximise these early warning signal, especially for small watersheds, require the use of rainfall predictions approaches (Yucel et al., 2015). One approach to extend the predictions of these early warning signals is the coupling of mesoscale numerical weather prediction (NWP) model precipitation estimates with a spatial resolution hydrological model into streamflow estimates (Jasper et al. 2002;Wardah et al. 2008; Yucel et al. 2015). The study explored (1) the potential of the NWP model (WRF) in reproducing observed precipitation over the Tono basin in West Africa, and (2) the potential of a coupled version of WRF with a physics-based hydrological model (WRF-Hydro) in estimating river streamflow. In order to cope with the lack of discharge observation in the Tono basin, the WRF-Hydro performances are evaluated with a water balance approach and dam level observation. The WRF-Hydro predicted dam level is relatively close to the observation (dam level) from January to August (R2=0.93). After this period the deviation from observation increases (R2=0.62). This could be attributed to surface runoff due to peak rainfall (in August) resulting in soil saturation (soil reaching infiltration capacity) into the dam which has not been accounted for in the water balance model. WRF-Hydro has shown to give good estimation of streamflow especially for ungauged stations. Further works requires using WRF-Hydro modeling system for climate projection, and assess the

  14. Can the SENSIMED Triggerfish®lens data be used as an accurate measure of intraocular pressure?

    The SENSIMED Triggerfish ® contact lens sensor (CLS) has an embedded micro-sensor that captures spontaneous circumferential changes at the corneoscleral junction and transmits them via an antenna to a device where these measurements are stored. During laparoscopic colorectal surgery, patients are placed in Trendelenburg position which has been shown to increase intraocular pressure (IOP). Laparoscopic colorectal surgery requires both pneumoperitoneum and Trendelenburg positioning; therefore, IOP can vary significantly. We aimed to assess whether circumferential changes in the corneoscleral area can be correlated to IOP changes measured using Tono-pen ® XL applanation tonometer during laparoscopic colorectal surgery. Patients undergoing laparoscopic colorectal resections were included. On the day of surgery, baseline IOP was taken and the SENSIMED Triggerfish ® CLS was then set up in one eye of the patient. During surgery (whilst under general anaesthetic), IOP measurements were taken in the contralateral eye using a Tono-pen ® XL applanation tonometer every hour and any time the table was moved to record the fluctuations of IOP during surgery and any association with position change. The timings of these readings were documented. Twenty patients were included in this study (six males, 14 females). Average age was 64.6 years (SD = 16.3). The fluctuation in IOP measured in the reference eye ranged between 6.3 and 46.7 mmHg. The mean correlation coefficient between CLS output measurements and these IOP measurements was r = 0.291 (95% CI). Our results showed a weak correlation between the SENSIMED Triggerfish ® CLS data output and IOP measurements taken using the Tono-pen ® XL applanation tonometer. © 2017 Acta Ophthalmologica Scandinavica Foundation.

    Stable overexpression of endothelial nitric oxide synthase (NOS-3) in HepG2 cells (4TO-NOS) leads to increased nitro-oxidative stress and upregulation of the cell death mediators p53 and Fas. Thus, NOS-3 overexpression has been suggested as a useful antiproliferative mechanism in hepatocarcinoma cells. We aimed to identify the underlying mechanism of cell death induced by NOS-3 overexpression at basal conditions and with anti-Fas treatment. The intracellular localization of NOS-3, the nitro-oxidative stress and the mitochondrial activity were analysed. In addition, the protein expression profile in 4TO-NOS was screened for differentially expressed proteins potentially involved in the induction of apoptosis. NOS-3 localization in the mitochondrial outer membrane was not associated with changes in the respiratory cellular capacity, but was related to the mitochondrial biogenesis increase and with a higher protein expression of mitochondrial complex IV. Nitro-oxidative stress and cell death in NOS-3 overexpressing cells occurred with the expression increase of pro-apoptotic genes and a higher expression/activity of the enzymes adrenodoxin reductase mitochondrial (AR) and cathepsin D (CatD). CatD overexpression in 4TO-NOS was related to the apoptosis induction independently of its catalytic activity. In addition, CatD activity inhibition by pepstatin A was not effective in blocking apoptosis induced by anti-Fas. In summary, NOS-3 overexpression resulted in an increased sensitivity to anti-Fas induced cell death, independently of AR expression and CatD activity. Copyright © 2015 Elsevier B.V.

    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)

  9. Change in Intraocular Pressure During Point-of-Care Ultrasound

    Directory of Open Access Journals (Sweden)

    Berg, Cameron

    2015-03-01

    Full Text Available Introduction: Point-of-care ocular ultrasound (US is a valuable tool for the evaluation of traumatic ocular injuries. Conventionally, any maneuver that may increase intraocular pressure (IOP is relatively contraindicated in the setting of globe rupture. Some authors have cautioned against the use of US in these scenarios because of a theoretical concern that an US examination may cause or exacerbate the extrusion of intraocular contents. This study set out to investigate whether ocular US affects IOP. The secondary objective was to validate the intraocular pressure measurements obtained with the Diaton® as compared with standard applanation techniques (the Tono-Pen®.   Methods: We enrolled a convenience sample of healthy adult volunteers. We obtained the baseline IOP for each patient by using a transpalpebral tonometer. Ocular US was then performed on each subject using a high-frequency linear array transducer, and a second IOP was obtained during the US examination. A third IOP measurement was obtained following the completion of the US examination. To validate transpalpebral measurement, a subset of subjects also underwent traditional transcorneal applanation tonometry prior to the US examination as a baseline measurement. In a subset of 10 patients, we obtained baseline pre-ultrasound IOP measurements with the Diaton® and Tono-Pen®, and then compared them.   Results: The study included 40 subjects. IOP values during ocular US examination were slightly greater than baseline (average +1.8mmHg, p=0.01. Post-US examination IOP values were not significantly different than baseline (average -0.15mmHg, p=0.42. In a subset of 10 subjects, IOP values were not significantly different between transpalpebral and transcorneal tonometry (average +0.03mmHg, p=0.07.   Conclusion: In healthy volunteer subjects, point-of-care ocular US causes a small and transient increase in IOP. We also showed no difference between the Diaton® and Tono-Pen® methods

Ii testo poetico viene cos trasformato in preghiera e ne adotta l´enunciazione. Attraverso i meccanismi linguistici dell´apostrofe e dell´allocuzione, il poeta personaggio è rappresentato come parlante a entità personificate o a persone presenti sulla scena d´enunciazione, mimando l´oralità primitiva della preghiera.

    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)

    Full Text Available Hasta el cuarto decenio del siglo, la pintura colombiana representó desnudos femeninos con poca frecuencia. Cuando lo hizo, fue para ilustrar propósitos moralizantes, como lo muestran dos ejemplares significativos: La mujer del levita, pintada por Epifanio Garay (1849-1903, y La última copa, de Francisco Antonio Cano (1865-1935. Hasta entonces los desnudos femeninos carecían de facciones precisas e incluso ocultaban el rostro; los cuerpos se presentaban generalmente en escorzo y la ausencia del vello púbico les confería un pretendido tono de inocencia y pudor cuyo contrapunto era la cuidadosa y sensual modelación ejercida por la luz sobre la piel.

    The early life history of anadromous salmonid fishes, be they Atlantic (Salmo salar) or Pacific salmon (Oncorhynchus spp.), trout of those genera, or charrs (Salvelinus spp.), appears much more complex than previously thought. The seaward movement or migration is extremely polymorphic among and within species. To help provide understanding of the processes involved, and implications for conservation, management and husbandry, the 8th International Workshop on Smoltification was held on September 20–24, 2009, with participants from 9 different countries. Because the native distribution of these fishes is in northern latitudes, more or less circumglobally, similar workshops have been held roughly every four years in various countries, starting in LaJolla, California; and subsequently in Stirling, Scotland; Trondheim, Norway; St. Andrews, Canada; Muonio, Finland; Westport, Ireland; and Tono, Japan. Papers emanating from these previous workshops can be found in earlier Special Issues of Aquaculture while those from the 2009 workshop are presented here.

    2016-01-01

    Full Text Available En este trabajo analizaré la manera en que Montañez redefine el concepto de diva en su colección de cuentos Las divas de mi barrio. 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.

    Eighteen species of gastropods were encountered living near and within the large coastal swamps, mangrove forests, intertidal flats and the rocky shore of the Cameroonian coast of the Atlantic Ocean. These represent members of the subclasses Neritimorpha, Caenogastropoda, and Heterostropha. Within the Neritimorpha, representatives of the genera Nerita, Neritina, and Neritilia could be distinguished by their radula anatomy and ecology. Within the Caenogastropoda, representatives of the families Potamididae with Tympano-tonos and Planaxidae with Angiola are characterized by their early ontogeny and ecology. The Pachymelaniidae are recognized as an independent group and are introduced as a new family within the Cerithioidea. Littorinimorpha with Littorina, Assiminea and Potamopyrgus as well as Neogastropoda (Thais) and Heterostropha (Melampus and Onchidium) are described and compared with representatives of the Caribbean and Indo-Pacific province.

    1998-01-01

    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

    To determine the central corneal thickness (CCT) by ultrasonic pachymetry and the effect of these values on the measurements of intraocular pressures (IOP) with rebound tonometry (TonoVet(®) ) in a captive flock of black-footed penguins (Spheniscus dermersus). Variations in CCT by age and weight, and variations in IOP by age were compared. Both eyes of 18 clinically normal black-footed penguins (Spheniscus dermersus) were used. The IOP was measured by the TonoVet(®) in both eyes of all the penguins. CTT measurements were performed 5 min later in all eyes using an ultrasound pachymeter. The mean IOP values ± SD were 31.77 ± 3.3 mm Hg (range of mean value: 24-38). The mean CCT values were 384.08 ± 30.9 μm (range of mean value: 319-454). There was no correlation between IOP and CCT values (P = 0.125). There was no difference in CCT measurements by age (P = 0.122) or weight (P = 0.779). A correlation was observed (P = 0.032) between IOP values and age. The coefficient of correlation was negative (ρ = -0.207). Ultrasound pachymetry has shown to be a reliable and easy technique to measure CCT in penguins. No correlation was observed between IOP and CCT values in this study. IOP showed a significant but weak decrease as age increased in the black-footed penguin. © 2014 American College of Veterinary Ophthalmologists.

    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.

    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.

    Full Text Available Currently, the existing information systems, and specifically the ERP, can not give adequate support to the management of manufacturing companies of ceramic tile, because, among other reasons, not to contemplate the existence of tone, size and quality within the same product. This feature, caused by the lack of homogeneity of the product (LHP, generates various problems in managing the product through the different business processes, such as, stocks management, order management, the production management, etc. Thus, it is necessary to develop an ERP solution that is able to manage adequately the ceramic product, including tone, size and quality. In this paper we analyze the requirements of the ceramic sector, in terms of product identification, and propose a data model to meet these requirements. The model arises as a basic guide for the development of vertical ERP solutions tailored to the ceramic industry.En la actualidad, los sistemas de información existentes, y en concreto los ERP, no pueden dar un soporte adecuado a la gestión de las empresas de fabricación de baldosa cerámica, debido, entre otros motivos, a que no contemplan la existencia del tono, calibre y calidad dentro de un mismo producto.

    Full Text Available OBJECTIVE: To assess the contribution of neonatal electroencephalogram (EEG and its correlation with the neurological examination at age of 9 months in newborns with bacterial neonatal meningitis. METHOD: Twenty seven infants were studied with positive cerebrospinal fluid (CSF culture for bacteria. We used the worse EEG result during acute phase of meningitis, and performed neurologic follow-up after discharge from hospital. Background cerebral activity was classified as normal or mildly, moderately, or markedly abnormal. Neurologic examination outcomes was classified normal, mild abnormalities, moderate abnormalities and severe abnormalities. RESULTS: EEG performed in the neonatal period during acute bacterial meningitis predicts adverse outcome early at age of 9 months, and had a significant correlation with cephalic perimeter and active tone alterations. CONCLUSION: Neonatal EEG is useful for predicting abnormal outcomes, especially cephalic perimeter and active tone abnormalities at 9 months of age in infants with bacterial neonatal meningitis.OBJETIVO: Medir la contribución del electroencefalograma (EEG neonatal y su correlación con el examen neurológico a la edad de 9 meses en recién nacidos con meningitis neonatal bacteriana.

    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.

Este fenómeno depende fundamentalmente de la interrelación entre el volumen sanguíneo, el tono vascular y el funcionamiento de la bomba cardíaca. La alteración de uno de ellos produce diferentes tipos de shock, para constituir el volumen el factor más afectado; este puede ser real y/o funcional, de ahí las diferencias en el manejo de la hemodinamia en el paciente críticamente enfermo. Los coloides en la actualidad, constituyen una opción eficaz para los diferentes casos de hipovolemia.The volume replacement is aimed at attaining an adequate perfussion at the cellular level and at preventing that the reperfussion be overadded to the ischemic process. This phenomenon depends mainly on the interrelation between the blood volume, the vascular tone and the functioning of the heart pump. The alteration of one of them produces different types of shock To be the most affected factor, the volume may be real and/or functional. That's why there are differences in the management of the hemodynamics in the critically ill patient. Colloids are at present an efficient option for the different cases of hypovolemia.

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.

    To describe the distribution and associations of demographic, familial, medical, and ocular factors with intraocular pressure (IOP). A cluster stratified random sample of urban and rural residents of Victoria, Australia, aged 40 years and older. Participants completed an interview and underwent a standardized dilated ophthalmic examination including measurement of IOP with an electronic applanation tonometer (Tono-Pen). Glaucoma status (possible, probable, definite) was determined by a consensus panel. The main outcome measure was IOP. The mean age of the 4576 participants was 59 years, 53% were women, 32% were born overseas, and 132 had open-angle glaucoma. Geometric mean (SD) IOP was 14.3 (+/-1.5) mm Hg. The relationship between IOP and nuclear sclerosis, iris color, and family history of glaucoma depended on glaucoma status. In those with glaucoma, family history of glaucoma and country of birth were significantly associated with IOP in multivariate models (model: r(2) = 0.08, P =.01). In the group without glaucoma, place of residence, use of alcohol, iris color, vitamin E intake, and spherical equivalent were associated with IOP (model: r(2) = 0.01, P =.006). In participants with glaucoma, genetic factors seem to be stronger predictors of IOP, whereas in those without glaucoma, lifestyle and physiological factors seem to play a greater role.

    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.

    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.

    Full Text Available La definición de la Psicología como ciencia de la conducta adoptada por el Conductismo supone e implica a su vez una conceptualización clara y unívoca de dicho concepto. Pero tal definición se enfrenta con una serie de malentendidos tenaces que dificultan no sólo la comprensión de dicho concepto básico sino también, en consecuencia, la propia conceptualización conductista. El propósito del presente trabajo es intentar exponer algunos de estos malentendidos, entre los que destacan los errores categoriales groseros, los procesos de reificación abusiva, los razonamientos tautológicos disfrazados, la generalización imprudente del modelo médico al ámbito de la conducta y la confusión nefasta entre un fenómeno y su conceptualización. Para ello, y con un tono más didáctico que académico, se recurre a una serie de metáforas de la vida cotidiana: la parte escondida del iceberg no es más que iceberg, las piedras no caen por su propio peso, los hombres y las mujeres no mueren porque son mortales, el bacilo de Koch existe y la máscara no es el rostro.

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.

    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.

    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.

    Full Text Available En los defectos de espesor total del párpado inferior de gran magnitud, siempre ha sido regla de oro la reconstrucción de la lamela posterior (tarso y conjuntiva palpebral. Esto es debido a que el tono del músculo orbicularis oculi no alcanza a mantener el soporte necesario para resistir la acción de la gravedad y/o contractura cicatricial. Además la ausencia de conjuntiva provocaría lesiones sobre la córnea ocular. Es por ello que el empleo de injertos compuestos condromucosos ha sido insustituible. El presente trabajo de investigación fue realizado en 20 conejos albinos con el objeto de evaluar la posibilidad de emplear cartílago auricular para la reconstrucción del tarso sin colocación de mucosa a modo de conjuntiva sobre dicho cartílago. Los resultados obtenidos permiten confirmar por diferentes tinciones histológicas sobre biopsias comparadas con zonas testigo, el crecimiento de tejido conjuntival sobre el pericondrio sin provocar lesiones oculares (neogénesis de conjuntiva. Los hallazgos encontrados provocan importantes y sustanciales cambios en la cirugía reconstructiva del párpado inferior debido a que de esta manera, no sería necesaria la reconstrucción de la conjuntiva palpebral, siendo útil exclusivamente la colocación de cartílago.

    Glaucoma, an irreversible optic nerve neuropathy, always results in blindness. This study aimed to evaluate glaucoma-like features in the rat episcleral vein cauterization (EVC) model by multiple in vivo and in vitro evidences. Wistar rat was used in this study. The elevated intraocular pressure (IOP) was induced by cauterization of three episcleral veins. IOP was monitored with Tono-Pen XL tonometer. Time-dependent changes to the neuronal retinal layers were quantified by Fourier domain-optical coherence tomography. The function of retina was evaluated by electroretinogram (ERG). Survival of retinal ganglion cells (RGCs) was quantified by retrograde labeling. Histology study was performed with retinal sections stained with hematoxylin-eosin, glial fibrillary acidic protein, and neuronal nuclear antigen. Retina and aqueous humor protein were extracted and cytotoxic protein tumor necrosis factor alpha (TNF-α) and alpha-2 macroglobulin (α2m) were measured with Western blotting. EVC is a relatively facile intervention, with low failure rates (EVC method can also induce glial cell activation and alterations of inflammation proteins, such as TNF-α and α2m. EVC method can establish a robust, reliable, economic and highly reproducible glaucomatous animal model.

    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.

    A comparison of loadings of N-nitrosamines and their precursors from different source water categories is needed to design effective source water blending strategies. Previous research using Formation Potential (FP) chloramination protocols (high dose and prolonged contact times) raised concerns about precursor loadings from various source water categories, but differences in the protocols employed rendered comparisons difficult. In this study, we applied Uniform Formation Condition (UFC) chloramination and ozonation protocols mimicking typical disinfection practice to compare loadings of ambient specific and total N-nitrosamines as well as chloramine-reactive and ozone-reactive precursors in 47 samples, including 6 pristine headwaters, 16 eutrophic waters, 4 agricultural runoff samples, 9 stormwater runoff samples, and 12 municipal wastewater effluents. N-Nitrosodimethylamine (NDMA) formation from UFC and FP chloramination protocols did not correlate, with NDMA FP often being significant in samples where no NDMA formed under UFC conditions. N-Nitrosamines and their precursors were negligible in pristine headwaters. Conventional, and to a lesser degree, nutrient removal wastewater effluents were the dominant source of NDMA and its chloramine- and ozone-reactive precursors. While wastewater effluents were dominant sources of TONO and their precursors, algal blooms, and to a lesser degree agricultural or stormwater runoff, could be important where they affect a major fraction of the water supply.

    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 Love of Don Perlimplin and Belisa in his Garden is one of the underprivileged works by Lorca’s critics, despite being a piece magnificently achieved. In it, García Lorca uses theater procedures that belong to different genres and tones, in order to destabilize the perception of the represented shares. These mechanisms of estrangement derive in the gradual transformation of the main character and the vision of the world that it projects, as result of a movement that transits from farce to tragedy.Amor de Don Perlimplín con Belisa en su jardín es una de las obras menos privilegiadas por la crítica lorquiana, a pesar de ser una pieza magníficamente lograda.

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.

    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 En los últimos años se ha constatado un aumento de estudios sobre los elemen - tos prosódicos del texto (tono, pausas, etc., que defienden la necesidad de trabajar estos componentes de la competencia comuni - cativa oral para mejorar la comprensión de los textos leídos en voz alta. Con el objetivo de estudiar las pausas como elementos que estructuran el discurso, en este estudio se computan los tipos de pausas, se identifican algunos aspectos a trabajar y, por último, se especifica el peso de algunas variables como las lenguas maternas, el género y la proce - dencia en la realización de las pausas den - tro de estructuras indivisibles. Para ello se ha realizado un experimento a partir de un texto periodístico, leído en voz alta, sobre un corpus de 100 informantes vascos bilingües con edades comprendidas entre los 18 y 25 años, y estudiantes de las Escuelas de Ma - gisterio de la UPV/EHU. Del estudio estadís - tico de los datos se concluye que los tipos de pausas más empleados por los jóvenes lecto - res son las silenciosas, que la posición de las pausas a menudo es incorrecta y que las len - guas maternas influyen significativamente en este hecho.

    Full Text Available El síncope asociado con el ejercicio es una condición que debe alertar al médico tratante; en primera instancia, se descartan alteraciones estructurales cardiacas que predispongan a muerte súbita, y en segundo lugar se evalúa la presencia de arritmias que potencialmente causen esta condición. En pacientes mayores de 35 años se descartan la enfermedad coronaria y las valvulopatías como eventuales causas. En sujetos que entrenan de manera frecuente, el tono vagal aumentado es una condición adaptativa común que a veces puede causar síncope cardioinhibitorio asociado con el ejercicio, cuya presentación puede variar desde bradiarritmias hasta asistolia, por lo cual constituye un reto diagnóstico.Exercise-induced syncope is a condition that should alert the treating physician; structural cardiac abnormalities that predispose to sudden death should be discarded, and the presence of arrhythmias that may potentially cause this condition are evaluated. In patients over 35 years, coronary and valvular disease are ruled-out as a possible cause of syncope associated with exercise. In subjects who train frequently, increased vagal tone is a common adaptive condition that may sometimes cause cardio-inhibitory syncope associated with exercise, whose presentation may vary from bradyarrhythmia to asystolia, thereby providing a diagnostic challenge.

    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.

    Tear production and intraocular pressures (IOPs) were determined in 38 and 102 wild Humboldt penguins (Spheniscus humboldti), respectively, from the Punta San Juan Marine Protected Area in Ica, Peru. Tear production was measured by Schirmer tear test, and IOP was measured with a TonoVet rebound tonometer. Adult (n = 90) and chick (n = 12) penguins were sampled from 2 different beaches (north and south facing) during 2 sampling years (2010 and 2011). Results showed a mean ± SD (range) of 9 ± 4 (2-20) mm/min for tear production and 28 ± 9 (3-49) mm Hg for IOP. Tear production in penguins differed between beach and sex, whereas IOP differed between age, year, and beach. The IOPs were negatively correlated with packed cell volume. Tear production and IOP values had greater variation in this population than it has in other avian species. Previous investigations of IOP and tear production in Spheniscus species were conducted with birds housed under professional care in artificial marine and freshwater environments. This is the first study, to our knowledge, investigating tear production and IOP in wild penguins and establishes valuable reference intervals for this species.

The aim of this study was to determine whether there is any difference between the effects of atracurium and cisatracurium on IOP and PD.Methods: Sixty patients with American Society of Anesthesiologists class I-II without history of previous eye surgery were studied in two randomly divided, double-blind groups. Following induction of anesthesia, atracurium (0.6 mg/kg and cisatracurium (0.15 mg/kg were administered to each group. IOP was measured by applanation tonometry (TONO – PEN ® XL and PD (COLVARD pupillometer at six sequential occasions, before induction of anesthesia, 2 and 5 minutes after induction and 2, 5 and 10 minutes after intubation prior to initiation of operation. Then they were compared to each other.Results: Trend of recorded IOP and PD values showed that there were no statistically significant differences between atracurium and cisatracurium according to their effect on IOP (p=0.125 and PD (p>0.137 during the course of study. Conclusion: It seems that both atracurium and cisatracurium have similar effects on IOP and PD before and up to ten minutes after tracheal intubation prior to surgical intervention.

    Full Text Available La cirugía multinivel (CMN es un real aporte en el manejo de pacientes con alteraciones neurológicas, especialmente en la parálisis cerebral donde, por el aumento del tono muscular durante el crecimiento, se producen deformaciones osteoarticulares, además de retracciones musculares que deterioran la marcha del paciente. Estas deformaciones se pueden corregir quirúrgicamente con la CMN basándose en los principios biomecánicos desarrollados a través del análisis tridimensional de la marcha. Esta cirugía logra recuperar los mecanismos antigravitatorios deteriorados de la marcha de pacientes con parálisis cerebral, permitiendo una marcha más funcional y con menos costo energético, lo que se ha corroborado con múltiples publicaciones internacionales que demuestran los beneficios de la cirugía y la duración en el tiempo de sus resultados. En el presente artículo se dan a conocer las bases de esta cirugía, haciendo énfasis en algunos procedimientos diagnósticos y terapéuticos.

  14. Antioxidant properties of melatonin--an emerging mystery.

    Over three centuries ago, the French philosopher René Descartes described the pineal gland as "the seat of the soul." However, it was not until the late 1950s that the chemical identity and biosynthesis of melatonin, the principal hormone secreted by the pineal body, were revealed. Melatonin, named from the Greek melanos, meaning black, and tonos, meaning color, is a biogenic amine with structural similarities to serotonin. The mechanisms mediating the synthesis of melatonin are transcriptionally regulated by the photoperiodic environment. Once synthesized, the neurohormone is a biologic modulator of mood, sleep, sexual behavior, reproductive alterations, immunologic function, and circadian rhythms. Moreover, melatonin exerts its regulatory roles through high-affinity, pertussis toxin-sensitive, G-protein (or guanine nucleotide binding protein) coupled receptors that reside primarily in the eye, kidney, gastrointestinal tract, blood vessels, and brain. Additional evidence also indicates a role for melatonin in aging and age-related diseases, probably related to its efficient free radical scavenger (or antioxidant) activity. The potential clinical benefit of melatonin as an antioxidant is remarkable, suggesting that it may be of use in the treatment of many pathophysiological disease states including various cancers, hypertension, pulmonary diseases, and a variety of neurodegenerative diseases such as Alzheimer's disease. This review summarizes the biosynthesis of melatonin and its many endocrine and physiological functions, including its therapeutic potential in human disease states. Emphasis is placed on the recent speculations indicating that this pineal hormone serves as an endogenous antioxidant agent with proficient free radical scavenging activity.

    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.

    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.

    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
