The line patterns on the masks are written into PMMA resist using a scanning electron microscope which has been interfaced to a personal computer equipped to control the x and y scan voltages. The opaque regions of the x-ray mask are then formed by electroplating fine grain gold into the open spaces in the etched PMMA. The mask and sample are mounted in an exposure cassette with a fixed spacer of 10 micrometers separating them. The x-ray patterning is carried out in an exposure chamber with flowing helium background gas in order to minimize debris deposition on the filters.
After etching the x-ray resist, the final patterns are produced using metallization and a standard lift-off technique. The SAW filters are then bonded and packaged onto impedance matching striplines. The resultant devices are tested using Scalar Network Analyzers. The final devices produced had a center frequency of 1. This report is a standardized methodology description for the determination of strong acidity of fine particles less than 2.
Modeling the language learning strategies and English language proficiency of pre-university students in UMS: This study aims to construct a mathematical model of the relationship between a student's Language Learning Strategy usage and English Language proficiency.
Bully (Fall Away, #1) by Penelope Douglas
Fifty-six pre-university students of University Malaysia Sabah participated in this study. A self-report questionnaire called the Strategy Inventory for Language Learning was administered to them to measure their language learning strategy preferences before they sat for the Malaysian University English Test MUET , the results of which were utilised to measure their English language proficiency. We attempted the model assessment specific to Multiple Linear Regression Analysis subject to variable selection using Stepwise regression. The model obtained suggests that not all language learning strategies should be included in the model in an attempt to predict Language Proficiency.

YAG laser in the treatment of rectosigmoideal tumors. Since January we have been using the combined Nd: The laser operates on the wavelength of 1.
Introduction of the laser into clinical practice was preceded by experimental operation, where we verified the interaction of laser emittance on both wavelengths with the tissues of colon, stomach, esophagus, and open surgery of the abdominal and thoracic cavities. To better understand the contribution of outdoor and indoor sources to particle concentrations found in residential indoor air, an extensive monitoring effort has been undertaken in a three-story townhouse located in Reston, VA.
Of particular interest was the determination of i Galaxy structural parameters from 3. We chose galaxies that had already been processed by the first three S4G pipelines Pipelines 1, 2, and 3; Sheth et al. In brief, Pipeline processes images and provides science-ready images. Pipeline 2 prepares mask images to exclude foreground and background objects for further analysis, and Pipeline 3 derives surface brightness profiles and total magnitudes using IRAF ellipse fits.

Spectral Irradiance Calibration in the Infrared. We present five new absolutely calibrated continuous stellar spectra from 1. All these spectra have a common calibration pedigree. The wavelength coverage is ideal for calibration of many existing and proposed ground-based, airborne, and satellite sensors. He identifies the basic issues facing the Brazilian Navy: Department of Defense, any other US Government agency, or any agency of a foreign government. Bars were identified based on the morphological classifications by Buta et al.

Besides, we provide a parameterization of the stellar contribution to the rotation curve and an estimate to the stellar-to-halo mass ratio within the optical radius for a sample of non-highly inclined galaxies i Aerosol microphysics simulations of the Mt. We use a stratosphere-troposphere composition-climate model with interactive sulfur chemistry and aerosol microphysics, to investigate the effect of the Mount Pinatubo eruption on stratospheric aerosol properties. Satellite measurements indicate that shortly after the eruption, between 14 and 23 Tg of SO2 7 to Best estimates of the peak global stratospheric aerosol burden are in the range 19 to 26 Tg, or 3.
In light of this large uncertainty range, we performed two main simulations with 10 and 20 Tg of SO2 injected into the tropical lower stratosphere. Simulated stratospheric aerosol properties through the to period are compared against a range of available satellite and in situ measurements. Stratospheric aerosol optical depth sAOD and effective radius from both simulations show good qualitative agreement with the observations, with the timing of peak sAOD and decay timescale matching well with the observations in the tropics and mid-latitudes.
However, injecting 20 Tg gives a factor of 2 too high stratospheric aerosol mass burden compared to the satellite data, with consequent strong high biases in simulated sAOD and surface area density, with the 10 Tg injection in much better agreement. Our model cannot explain the large fraction of the injected sulfur that the satellite-derived SO2 and aerosol burdens indicate was removed within the first few months after the eruption.
We suggest that either there is an additional alternative loss pathway for the SO2 not included in our model e. Overall, the model captures remarkably well the complex variations in particle concentration profiles across the different OPC size channels. However, for the 19 to 27 km injection height-range used here, both runs have a modest high bias in the lowermost stratosphere for the finest particles radii less than nm , and the decay timescale is longer in the model for these particles, with a much later return to background conditions.
Also, whereas the 10 Tg run compared best to the satellite measurements, a significant low bias is apparent in the coarser size channels in the volcanically perturbed lower stratosphere. Overall, our results suggest that, with appropriate calibration, aerosol microphysics models are capable of capturing the observed variation in particle size distribution in the stratosphere across both volcanically perturbed and quiescent conditions. Furthermore, additional sensitivity simulations suggest that predictions with the models are robust to uncertainties in sub-grid particle formation and nucleation rates in the stratosphere.
The relationship between English language learning strategies and gender among pre-university students: An overview of UMS. This study aims to analyze the effects psychological gender differences on the relationship between language learning strategies and their proficiency in English language for pre-university students.
Previous researchers found that the more employment of language learning strategies, the more successful the learners are and those with higher level of strategy use are female rather than male. In this study, fifty-six pre-university students 22 males, 34 females of University Malaysia Sabah participated in this study. Pearson's correlation coefficient, one-way analysis of variance ANOVA and the t-test were utilized to make statistical interpretation about the relationship.

Evaluation of the performance of actions and outcomes in primary health care. The objective of this study has been to evaluate the performance of the primary care of Brazilian municipalities in relation to health actions and outcomes.
This is an evaluative, cross-sectional research, with a quantitative approach, aimed at the identification of the efficiency frontier of the primary care in health actions and outcomes in Brazilian municipalities. The data envelopment analysis tool has been used for variable returns to scale with product orientation.
Municipalities have been analyzed by population size, and small municipalities have presented a high percentage of inefficiency for both models. The analysis of efficiency has indicated the existence of a higher percentage of effective municipalities in the model of health actions than in the model of health outcomes. To assess clinical and epidemiological characteristics of patients with Chagas disease, younger than 18 years, who had undergone pacemaker implantation in Brazil between and , and its temporal trend.
This was a cross-sectional analysis of data from the Brazilian Pacemaker Registry database. The following variables were analyzed: In a total of , implants performed between and , implants of cardiac stimulation device in Chagas disease patients aged younger than 18 years were identified. Mean age at implantation was 5. Fifty-six percent of the procedures were performed in the southeast region. Regarding the total number of pacemaker implants per year, there was a remarkable increase in the implants for all causes. However, time series analysis of the implants in Chagas disease patients younger than 18 years revealed a significant reduction in the annual number of implants.
There has been an important reduction in the number of pacemaker implantations among children and adolescents with Chagas disease, suggesting a reduction in the vertical transmission of the parasite.
