Um estudo sobre a utilização de Símbolos Pictóricos Táteis em Mapas Temáticos para o Ensino de Geo-grafia no âmbito do Desenho Universal
Authors: Faria Andrade Andrea , Castro Monteiro Caroline de
Published: December 2019

Este trabajo tuvo como objetivo evaluar el uso de mapas temáticos táctiles con simbología pictórica, que se utilizarán en base al Diseño Universal para el Aprendizaje (DUA). Por lo tanto, es posible utilizar el material didáctico de todos los niños, promoviendo la inclusión de estudiantes con discapacidad visual en la experiencia social y la comunicación con visionarios. Para eso, se hicieron dos mapas con patrones de simbologías distintas: pictórica y abstracta. Los mapas se modelaron en software 3D y se imprimieron utilizando la tecnología Rapid Prototyping. Las pruebas de percepción de estas simbologías se realizaron con estudiantes con discapacidad visual y visual en una escuela en Curitiba, Paraná. A partir de los primeros resultados obtenidos en esta investigación, se sugiere que se indique que la simbología pictórica se utiliza para la representación de características puntuales en el mapeo táctil, ya que era más atractiva para todos los participantes y estimulaba a los estudiantes con discapacidad visual a interacción social y para usar más allá del tacto, lenguaje, que contiene los principios del diseño universal. Sin embargo, al igual que con el uso de símbolos pictóricos para los videntes, algunos símbolos son aprehendidos a medida que se observan y usan en la vida cotidiana, haciéndolos sujetos a la estandarización y al uso universal. El diseño de estos símbolos de la impresión 3D demostró ser efectivo porque permite el modelado de geometrías complejas, lo que permite la combinación de recursos visuales y táctiles para generar mapas desde la perspectiva del Diseño Universal, así como para producir materiales duraderos y fácilmente reproducibles.

Treatment of textile wastewater prior to its discharge into the environment is a highly concerned issue of the industry.
The current established methods in textile industry for effluent treatment are typically high in cost, require range of
chemicals along with the generation of concentrated hazardous sludge. It is therefore inevitable to look for economical
and eco-friendly ways to treat textile wastewater. Hence, the present study was endeavored to develop green, chemical
free and sustainable bacteria inoculated plant based technique for remedying textile bleaching effluents. A lab scale
floating treatment wetlands (FTWs) system was developed and implemented for remediation of H2O2 based textile
bleaching wastewater. This system was designed by vegetating two free floating aquatic plants Eichhorniacrassipes and
Pistia stratiotes. The performance of this system was enhanced by inoculating two pollutant degrading and plant growth
promoting bacteria, Bacillus cereus and Bacillus subtilis. The efficacy of this bacterial augmented FTWs system was
assessed by monitoring physicochemical parameters of treated wastewater. A substantial decrease in pH, EC, TDS,
TSS, BOD and COD was noted. This stamped the effectiveness of this sustainable technique to treat textile effluents.

Capacity Bounds for Dense Massive MIMO in a Line-of-Sight Propagation Environment
Authors: Pereira de Figueiredo Felipe Augusto , Dias Claudio Ferreira , Rodrigues de Lima Eduardo , Fraidenraich Gustavo
Published: December 2019

The use of large-scale antenna arrays grants considerable benefits in energy and spectral efficiency to wireless systems due to spatial resolution and array gain techniques. By assuming a dominant line-of-sight environment in a massive MIMO scenario, we derive analytical expressions for the sum-capacity.

%

Then, we show that convenient simplifications on the sum-capacity expressions are possible when working at low and high SNR regimes.

%

Furthermore, in the case of a high SNR regime, it is demonstrated that the Gamma PDF can approximate the PDF of the instantaneous channel sum-capacity as the number of BS antennas grows. A second important demonstration presented in this work is that a Gamma PDF can also be used to approximate the PDF of the summation of the channel's singular values as the number of devices increases. Finally, it is important to highlight that the presented framework is useful for a massive number of Internet of Things devices as we show that the transmit power of each device can be made inversely proportional to the number of BS antennas.

Authors: Campuzano-Maya Germán
Published: December 2019

Una prueba diagnóstica, incluidas las del laboratorio clínico, las de patología y las de radiología en sus múltiples aplicaciones, es de utilidad clínica cuando su desempeño analítico alcanza indicadores de precisión y exactitud ideales, es decir, lo más cercano al 100%, cuando se utiliza en el diagnóstico, clasificación y manejo de un grupo de enfermedades para las cuales se ha diseñado. En el caso de las enfermedades hepáticas, ninguna de estas pruebas, hasta el momento disponibles, logra este objetivo e incluso están lejos de alcanzarlo, aun cuando son críticas en el diagnóstico y manejo de estas enfermedades. Con el descubrimiento de que el estómago podía ser colonizado con una bacteria, hoy denominada Helicobacter pylori, y el desarrollo posterior de la prueba de aliento con urea marcada con carbono 13 (13C-urea), múltiples pruebas de aliento han sido desarrolladas con sustratos marcados con 13C, siendo la prueba de aliento 13C-metacetina la más representativa para determinar la función hepática por esta metodología. En este módulo se presenta la prueba de aliento con 13C-metacetina como una nueva alternativa, no invasiva, para el estudio de la función hepática en el diagnóstico y seguimiento de las enfermedades del hígado. Además, se presentan los fundamentos de la prueba, los métodos para realizarla, la interpretación de los resultados, las limitaciones y las indicaciones de la misma.
Community-Level Resource Development and Management, Part 2: A Transferable Approach to Feasibility Analysis for Biogas as an Alternative Cooking Fuel
Authors: Richardson Megan McWalter , Sharp Kendra V.
Published: December 2019

Energy access for all is the seventh Sustainable Development Goal (SDG) put forth by the United Nations in 2015. This initiative has been taken on by many non-governmental organizations (NGOs), national governments and communities alike. Traditional approaches to cooking often rely on three-stone fires (or other open wood fires). The smoke from these open cooking fires is known to cause significant negative health impacts, thus access to cleaner energy sources is especially important for to improve cooking conditions. One alternative cooking fuel is biogas, which has the advantages of smoke reduction, and decreased reliance on and impact of firewood collection. In this article, we develop a method of analyzing the feasibility of biogas projects for rural communities. The method enables both evaluation of an ideal digester design for specific environments and determination of the scale, cost, and yields of a biogas plant. For example, in a cooking application 1-m3 of biogas can be compared to 1.3 kg of firewood or approximately 10 minutes not spent collecting firewood. Such evaluation is critical to help communities and organizations determine whether or not this type of project is ideal for their environments. All too often, development project concepts are funded prematurely, before the realization that the implemented technology does not function properly or is unsustainable for specific applications. The feasibility analysis we describe is a contribution to the literature because it provides a condensed, simplified resource that enables development practitioners and communities to readily evaluate whether or not a biogas energy solution is appropriate and sustainable for their setting prior to investing valuable resources and time into implementation.

Reorganización administrativa de una institución pública: Construcción de la estructura orgánica formal del Despacho del Gobernador del Estado de San Luis Potosí, México
Authors: Alavez Torres Ismael , Vega Campos Miguel Ángel
Published: December 2019

La elaboración de este trabajo surgió por la inquietud de documentar las acciones y estrategias que se ejecutaron para la reorganización administrativa del Despacho del Gobernador del Estado de San Luis Potosí, durante el periodo constitucional 1997-2003, a cargo de Fernando Silva Nieto. Se considera que un trabajo de estas características puede aportar evidencia empírica que sirva de referencia para otras organizaciones públicas -ya sean federales, estatales o municipales- que se interesen por la ejecución de acciones en el mismo sentido; es decir, puede ayudar desde el punto de vista jurídico, administrativo, técnico, metodológico, entre otros aspectos. Se trata de un trabajo realizado bajo un enfoque preponderantemente cualitativo, en virtud de que el mismo se apoyó casi en su totalidad de revisión documental, aunque también están inmersos en el estudio las experiencias y vivencias de los autores de esta investigación, quienes se desempeñaron como servidores públicos durante el periodo revisado y a quienes les tocó dirigir las acciones que aquí se documentan. Además de la descripción de las acciones y estrategias que se realizaron para el propósito de la reorganización, también se incluyen los productos que se generaron, derivados de dichas actividades.

Published: December 2019

With 118.400 hectare of concession area and employed people for more than 21.694 employees within company and from business partners, Berau Coal needs to put more concern in managing operational and health, safety and environment (SHE). The challenges that need to be faced are location that scattered into 4 operational areas, limited time for employess to access information because most of time exploitated for working, various educational background, and technology literacy. Berau Coal has been developed a learning platform, named SINTESIS+ and SID. The aims in development of those platforms are; (1) as a operational and HSE-themed learning platform, (2) toincrease capacity and to build HSE and operational competencies, (3) to increase operational control for competencies related to entry permit, work permit, license, and specialization, and (4) to intervene employees’ behaviour to build safety culture. Features and contents that has been embedded in SINTESIS+ are online learning with multimedia materials, online testing with real time result, webinar, incident and mining operational news, repositories for employees’ portfolio, event and training registration, integrated with SID to recordemployees’ historical competency-related data, and sustainable process to increase HSE awareness. Since its launching, SINTESIS+ has been accessed by 7867 employees, tested for 1024 exams, conducted webinar that participated by 330 employees, and run more effective and efficient processes. Impacts from integration process with SID are the increase of compliance level for competencies to 98% and the increase of process control efficiency. With those increments, beside the employees’ compency and HSE awareness is increased, hoped to lower incident rate. In the future, to improve access to the platform, Berau Coal is willing to develop mobile apps forSINTESIS+.

New s-process Mechanism in Rapidly Rotating Massive Population II Stars
Authors: Banerjee Projjwal , Heger Alexander , Qian Yong-Zhong
Published: December 2019

We report a new mechanism for the s-process in rotating massive metal-poor stars. Our models show that above a critical rotation speed, such stars evolve in a quasi-chemically homogeneous fashion, which gives rise to a prolific s-process. Rotation-induced mixing results in primary production of 13C, which subsequently makes neutrons via

during core He burning. Neutron capture can last up to

(∼3 × 105 yr) with the peak central neutron density ranging from ∼107 to 108

. Depending on the rotation speed and the mass loss rate, a strong s-process can occur with production of elements up to Bi for progenitors with initial metallicities of [Z] ≲ −1.5. This result suggests that rapidly rotating massive metal-poor stars are likely the first sites of the main s-process. We find that these stars can potentially explain the early onset of the s-process and some of the carbon-enhanced metal-poor (CEMP-s and CEMP-r/s) stars with strong enrichment attributed to the s-process or a mixture of the r-process and the s-process.
Long-term Variability and Correlation Study of the Blazar 3C 454.3 in the Radio, NIR, and Optical Wavebands

We performed a long-term optical (B, V, R bands), infrared (J and K bands), and radio band (15, 22, 37 GHz band) study of the flat spectrum radio quasar, 3C 454.3, using data collected over a period of more than 8 yr (MJD 54500–57500). The temporal variability, spectral properties, and interwaveband correlations were studied by dividing the available data into smaller segments with more regular sampling. This helped us constrain the size and the relative locations of the emission regions for different wavebands. Spectral analysis of the source revealed the interplay between the accretion disk and jet emission. The source predominantly showed a redder-when-brighter trend, though we observed a bluer-when-brighter trend at high flux levels, which could be a signature of particle acceleration and radiative cooling. Significant correlations with near-zero lag were seen between various optical and infrared bands, indicating that these emission regions are cospatial. Correlations with a time lag of about 10–100 days are seen between the optical/infrared and radio bands indicating these emissions arise from different regions. We also observe the DCF peak lag change from year to year. We try to explain these differences using a curved jet model where the different emission regions have different viewing angles resulting in a frequency-dependent Doppler factor. This variable Doppler factor model explains the variability timescales and the variation in DCF peak lag between the radio and optical emissions in different segments. Lags of 6–180 days are seen between emissions in various radio bands, indicating a core-shift effect.
X-Ray Spectra from Plasmas with High-energy Electrons: κ-distributions and e−–e− Bremsstrahlung
Authors: Cui Xiaohong , Foster Adam R. , Yuasa Takayuki , Smith Randall K.
Published: December 2019

Shocks, turbulence, and winds all influence the electron velocity distribution in hot plasmas, exciting lower-energy electrons and generating a high-energy (typically power-law) tail. This effect, typically described as a κ distribution can affect both the line and continuum X-ray spectra emitted by the plasma. Hahn & Savin proposed a “Maxwellian decomposition” to generate the rate coefficients of κ distributions. Using their method and the AtomDB atomic database, we have developed a general model to calculate the emission from a plasma with a κ distribution. We compare our κ results for the charge state distribution and spectra of oxygen with those from KAPPA package with the ion data available within the CHIANTI atomic database. Sufficiently energetic electrons, created either in a κ distribution or merely a very hot Maxwellian plasma, can also emit via electron–electron (e–e) bremsstrahlung, a process not previously included in AtomDB. We have added this process to AtomDB and apply it to calculate the temperature gradients, as well as the total spectra from the post-shock regions of an accreting magnetic cataclysmic variable. We find the contribution of e–e bremsstrahlung to the total spectra exceeds 10% at KT ∼ 100 keV, with the total emissivity in the post-shock accretion stream differing by more than 10% at energies above 60 keV.
The Galaxy Power Spectrum from TGSS ADR1 and the Effect of Flux Calibration Systematics
Authors: Tiwari Prabhakar , Ghosh Shamik , Jain Pankaj
Published: December 2019

We explore the large to moderate scale anisotropy in distant radio sources using the TIFR GMRT Sky Survey (TGSS) ADR1 catalog. We use different measures, i.e., number counts, sky brightness, and flux per source, for this study. In agreement with earlier results, we report a significant excess of clustering signal above the angular scale of roughly 10° (i.e., l ⪅ 20–30). We find that some survey areas have a systematically low/high flux and argue this may be the cause of the observed signal of excess power at low multipoles. With mocks we demonstrate the effect of such large-scale flux systematics and recover a TGSS-like excess clustering signal by assuming 20% flux uncertainties over ∼10° × 10° sized patches. We argue that that TGSS at this stage, i.e., TGSS ADR1, is not suitable for large-scale clustering measurements. We find that the measure, flux per source, shows evidence of isotropy for all multipoles l > 2 despite the presence of systematics in the data.

Published: December 2019

We present the analysis of Chandra and NuSTAR spectra of NGC 4968, a local (D ∼ 44 Mpc) 12 μm selected Seyfert 2 galaxy, enshrouded within Compton-thick layers of obscuring gas. We find no evidence of variability between the Chandra and NuSTAR observations (separated by 2 yr), nor between the two NuSTAR observations (separated by 10 months). Using self-consistent X-ray models, we rule out the scenario where the obscuring medium is nearly spherical and uniform, contradicting the results implied by the <10 keV Chandra spectrum. The line-of-sight column density, from intervening matter between the source and observer that intercepts the intrinsic active galactic nucleus (AGN) X-ray emission, is well within the Compton-thick regime, with a minimum column density of 2 × 1024 cm−2. The average global column density is high (>3 × 1023 cm−2), with both Compton-thick and Compton-thin solutions permitted, depending on the X-ray spectral model. The spectral models provide a range of intrinsic AGN continuum parameters and implied 2–10 keV luminosities (L
2–10 keV,intrinsic), where the higher end of L
2–10 keV,intrinsic is consistent with expectations from the 12 μm luminosity (L
2–10 keV,intrinisc ∼ 7 × 1042 erg s−1). Compared with Compton-thick AGN previously observed by NuSTAR, NGC 4968 is among the most intrinsically X-ray luminous. However, despite its close proximity and relatively high intrinsic X-ray luminosity, it is undetected by the 105 month Swift-Burst Alert Telescope survey, underscoring the importance of multiwavelength selection for obtaining the most complete census of the most hidden black holes.
Neuromyelitis Optica Spectrum Disorder: A Case Report of Effective Combination Immunosuppressant, Corticosteroids, and Therapeutic Plasma Exchange
Authors: Tambunan Laura , Ritarwan K. , Surbakti K. P.
Published: December 2019

BACKGROUND: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease that causes severe demyelination, especially in the optic nerve and spinal cord with typical clinical manifestations of acute optic neuritis and transverse myelitis. The symptoms can occur simultaneously or separated by a variable period. NMOSD is associated with serum aquaporin antibodies 4 immunoglobulin G (AQP4-IgG).
CASE PRESENTATION: We report a case of a 22-year-old male with complaints of weakness of all four limbs, impaired vision, urinary incontinence, and dyspnea. The Expanded Disability Status Scale (EDSS) was nine. Spinal magnetic resonance imaging (MRI) showed longitudinal extensive transversal myelitis. The brain MRI showed a normal impression, whereas the brain magnetic resonance spectroscopy (MRS) examination showed a description of the mild demyelination process. The serum antibody AQP4 (AQP4-IgG) results were seronegative, the cerebrospinal fluid examination was normal, and the oligoclonal band was negative. The ophthalmoscopic examination found bilateral papillary atrophy but optical coherence tomography (OCT) was still normal. Somatosensory evoked potential and visual evoked potential examinations were abnormal. The patient was diagnosed with NMOSD and was given combination immunosuppressant therapy, corticosteroids, and therapeutic plasma exchange. The patient experienced significant improvement with EDSS decreased to six.
CONCLUSION: In the case of relapsing NMOSD patient, combination therapy of immunosuppressants, corticosteroids, and TPE was used. There were significant improvements from EDSS nine to six.

BACKGROUND: The most widely used tumour markers, especially in colorectal malignancy, is Carcinoembryonic antigen (CEA).
AIM: This study was aimed to investigate CEA value among the degree of differentiation and tumour location.
METHODS: A cross-sectional analytical study was used in this study on eighty consecutive patients with colorectal carcinoma (CRC) at Adam Malik General Hospital and Permata Bunda Hospital, Medan, Indonesia. All data were analysed using SPSS for Windows version 21.
RESULTS: They were rectal cancer 49.4%, left-sided colon cancer 43.2% and right-sided colon cancer 6.2%. Histopathology findings were well-differentiated 40.7%, moderate differentiated 32.1% and poorly differentiated 25.9%. There were no correlations between CEA level and haemoglobin level, white blood cells count, and platelet count. There was no significant difference between CEA and location of the tumour (p = 0.70), although CEA level was significantly differenced among histopathology findings (p = 0.03). CEA levels were and associated with the degree of differentiation.
CONCLUSION: CEA levels increased in well-differentiated colorectal carcinoma especially in rectal cancer.
The Association between CD-4 Level, Stress and Depression Symptoms among People Living with HIV/AIDS
Authors: Effendy Elmeida , Amin Mustafa M. , De Vega Lidya , Utami Nurul
Published: December 2019

BACKGROUND: The lives of individuals diagnosed with HIV and the subsequent illness, AIDS, were often chaotic because these individuals deal with the physical, emotional, and interpersonal sequelae of this illness. Depressive symptoms and stress were common and impact on functioning, quality of life, and health status, highlighting the importance of diagnosis and treatment of patients with HIV infection. Psychiatric clinical practice and rating scales have come to play an ever-increasing role both in determining specific symptoms and diagnosing an individual condition. Descriptive reports of psychiatric morbidity among those with HIV infection, that relied primarily on self-report rating scales, described high rates of symptomatic depression and stress.
AIM: This study aimed to determine the proportion of depression among people living with HIV/AIDS using the BDI-II and PSS to determine a relationship between symptoms of depression and stress with CD4 counts.
METHODS: This study was a numerical correlative analytic study with a cross-sectional study approach that assessed the correlation between stress, depression and CD4 level in people with HIV/AIDS that were receiving ARV therapy in the Voluntary Counselling Test (VCT) Polyclinic of General Hospital Haji Medan by recruiting 46 subjects. CD4 level was examined in the Pramita Medan laboratory.
RESULTS: When analysis of BDI-II level and CD4 scores were done, a significant correlation was found (P < 0.05). The strength of the relationship between the BDI score and the CD4 score was 0.548 revealing a positive correlation with moderate correlation strength
CONCLUSION: We have shown a significant relationship between depression, stress and CD4 level among people with HIV/AIDS in Medan, Indonesia. Psychological distress may affect the immunity in infected people, leading to the disease progressivity.

Queer comrades: towards a postsocialist queer politics
Authors: Bao Hongwei
Published: December 2019

Perhaps one of the most fascinating changes in modern Chinese language in the past century is the use of the term tongzhi (). Literally 'comrade', the term is being used in the Chinese-speaking world today to refer to gender and sexual minorities, including LGBTQ people. This article
traces a brief history of how the term has been used in modern Chinese history. In doing so, it identifies key moments of political articulation and unravels the socialist politics and revolutionary potentials embedded in each articulation. In particular, it focuses on how the term has been
used in the Chinese-speaking world for queer identification and to mobilise transnational activism. Developing the idea of 'queer comrades' as a part of critical vocabulary, this article conjures up the socialist memories and revolutionary impulses that are embedded in contemporary queer subject
formation and social movements; it also gestures to the continuing relevance of socialist histories and politics to contemporary queer politics.

Published: December 2019

ABSTRACT

PURPOSE: To evaluate the amount of miosis induced by over-minused lenses and to assess subjective reduction of halos following laser in situ keratomileusis (LASIK) with such lenses.

METHODS: Part I: Infrared pupil diameter was assessed in 14 patients who had not had ocular surgery. The accommodative/miotic reflex was stimulated with concave trial lenses in -1.00-D increments up to -4.00 D while viewing the 20/40 acuity line. Part II. Subjective halos around a distant light were assessed in 14 patients following LASIK for myopia, with and without a -1.00-D lens over manifest refraction.

RESULTS: Part I: 100%, 79%, and 64% of patients clearly saw the 20/40 line with a -1.00-D lens, -2.00-D lens, and -3.00/-4.00-D lens, respectively. Mean pupil diameter decreased by 0.2 mm with the -1.00-D lens (P=.02), 0.5 mm with the -2.00-D lens (P=.003), 0.9 mm with the -3.00-D lens (P=.008,), and 1.1 mm with the -4.00-D lens (P=.008). Part II: 11 of 14 patients (79%) noticed a decrease in the size of the halo (30% average reduction) when overminused by -1.00 D.

CONCLUSIONS: Pupil diameters and halos decreased with a -1.00-D overcorrection in patients following LASIK. Patients with pupil-dependent night halos after LASIK may benefit from mildly over-minused lenses. [J Refract Surg 2004;20: 149-154]
Bilateral Comparison of Wavefront-guided Versus Conventional Laser in situ Keratomileusis With Bausch and Lomb Zyoptix
Authors: Kim Tae-im , Yang Seung-jae , Tchah Hungwon
Published: December 2019

ABSTRACT

PURPOSE: One aim of corneal refractive surgery is to correct defocus and astigmatism. In the process of correcting lower order aberrations, higher order ocular aberrations increase. To evaluate the effectiveness of wavefront-guided laser in situ keratomileusis (LASIK) in reducing the increase of higher order aberration, we compared aberrational change after LASIK with conventional and wavefront-guided customized ablation.

METHODS: Our study included 48 eyes of 24 patients. We performed conventional LASIK in one eye (Group 1) and wavefront-guided customized ablation in the other eye (Group 2). Ocular aberration was measured with the Zywave, a type of Shack-Hartmann aberrometer. We then compared low and high order aberrations, contrast sensitivity, visual acuity, corneal topography, and manifest refraction preoperatively and postoperatively at 1 and 3 months.

RESULTS: Uncorrected visual acuity improved to more than 20/20 in two eyes in the conventional ablation group and in five eyes in the customized ablation group. In the conventional ablation group, Root-mean-square for higher order (RMSH was 0.215 preoperatively, 0.465 (216.3%) at 1 month, and 0.418 (194.4%) at 3 months. In the customized ablation group, RMSn was 0.207 preoperatively, 0.380 (183.6%) at 1 month, and 0.371 (179.2%) at 3 months after LASIK. Mesopic contrast sensitivity in the customized ablation group was higher than that in the conventional ablation group, but this change was not statistically significant.

CONCLUSIONS: Wavefront-guided customized ablation reduced the increase of high order aberrations resulting from LASIK. In terms of visual acuity, patient preference, and mesopic contrast sensitivity, wavefront-guided customized ablation produced slightly-but not statistically significantbetter results.

Astigmatic Power Calculations for Intraocular Lenses in the Phakic and Aphakic Eye
Authors: Sarver Edwin J , Sanders Donald R
Published: December 2019

ABSTRACT

PURPOSE: To develop sets of equations employed in the power calculations for toric intraocular lenses (IOLs) in phakic or aphakic astigmatic eyes.

METHODS: Mathematical operations to convert from standard toric parameters of sphere, cylinder, and axis to astigmatic decomposition components, and vice versa, are presented. These operations are used to derive equations to calculate the ideal toric IOL power for a phakic or aphakic astigmatic eye, predict the postoperative spectacle correction for a selected toric IOL with power other than the ideal power, and back calculate a parameter to be used to optimize predictability of the calculations based on clinical data.

RESULTS: Two numerical examples are provided to show how the equations are used with clinical data.

CONCLUSION: The equations developed provide a method to perform toric IOL power calculations and supporting operations of predicted postoperative spectacle refraction and optimization of prediction error for phakic and aphakic eyes with astigmatism. [J Refract Surg 2004;20:472-477]
Improving Visual Function Diagnostic Metrics With the Use of Higher-order Aberration Information From the Eye
Authors: Campbell Charles E
Published: December 2019

ABSTRACT

PURPOSE: This paper reviews the currently used visual function diagnostic metrics, acuity, refractive error, and contrast sensitivity, and suggests ways to create new metrics using the information that has recently become available due to advances in measuring the higher-order aberrations of the eye. Particularly, emphasis is placed on finding metrics that address certain aspects of vision rather than on general metrics.

METHODS: Two metrics based on the modulation transfer function are introduced, the Visual Quality Factor (VQF), which is a value based on the modulation transfer function between the spatial frequencies of 3 and 12 cycles per degree (c/deg) giving a measure of the overall degradation of visual quality due to aberrations, and the Subjective Sharpness Factor (SSF), which is a value based on the modulation transfer function between the spatial frequencies of 15 and 40 c/deg, giving a measure of the decrease in perceived image "sharpness" due to aberrations. Two metrics based on the point spread function are suggested, Point Spread Quality (PSQ), which is a measure of the "compactness" of the point spread, and Multiplicity Factor, which is a measure of the multiplicity of perceived images by measuring the number of discrete peaks in the point spread function.

RESULTS: The VQF and SSF values for both monochromatic and polychromatic cases are analyzed with regard to the number of acuity letters lost using data from a published study.

CONCLUSIONS: The SSF is found to be the best overall correlate with acuity performance if the degradation of the letter stimuli is not excessive. [J Refract Surg 2004;20:S495-S503]
Confocal Microscopy in Early Diagnosis of Acanthamoeba Keratitis
Authors: Nakano Eliane , Oliveira Marivaldo , Portellinha Waldir , de Freitas Denise , Nakano Kozo
Published: December 2019

ABSTRACT

PURPOSE: This study correlated confocal microscopic images obtained using the Nidek ConfoScan 2.0 System in corneas with clinical suspicion of Acanthamoeba keratitis, with diagnosis confirmed by either cytological and/or histological analysis.

METHODS: Fifteen eyes of 14 patients with a clinical diagnosis of Acanthamoeba keratitis underwent confocal microscopy evaluation.

RESULTS: Fifteen eyes of 14 patients (one bilateral case) showed Acanthamoeba keratitis alterations that ranged from massive infestation to cicatricial opacity in the stroma. Ten patients (71%) were females. Mean age was 26 years (range 19 to 37 yr). All patients were contact lens wearers.

CONCLUSION: Confocal microscopy was a useful, noninvasive technique in the diagnosis and treatment of Acanthamoeba keratitis, especially in those cases in which corneal scraping, cytological analysis, and culture are negative. It also eliminated the necessity of tissue biopsy, considered an invasive procedure. [J Refract Surg 2004;20 (suppl): S737-S740]
Implantation of Artisan Toric Phakic Intraocular Lenses for the Correction of Astigmatism and Spherical Errors in Patients With Keratoconus
Authors: Budo Camille , Bartels Marjolijn C , van Rij Gabriel
Published: December 2019

ABSTRACT

PURPOSE: To evaluate the correction of astigmatism and spherical ametropia in patients with keratoconus through implantation of an Artisan toric phakic intraocular lens (PIOL) (Ophtec, Groningen, The Netherlands).

METHODS: Artisan toric PIOLs were implanted uneventfully in both eyes of three patients with keratoconus with clear central corneas and contact lens intolerance.

RESULTS: Best spectacle-corrected subjective visual acuity after lens implantation was unchanged in one eye and improved in five eyes. Spherical equivalent refraction was significantly reduced in all eyes (P=. 03). The safety index was 1.49.

CONCLUSIONS: The implantation of an Artisan toric PIOL may be an alternative for treating astigmatism and myopia in contact lens intolerant patients with keratoconus with clear central corneas. Especially in patients with associated myopia, this procedure is worth considering before planning a penetrating keratoplasty. [J Refract Surg. 2005;21:218-222.]
La Claudia Jerónima del Quijote: de virgo bellatrix de libro de caballerías a nyerra catalana
Authors: Domènech Conxita
Published: December 2019

La historia intercalada de Claudia Jerónima posee todos los ingredientes propios de un libro de caballerías. Miguel de Cervantes se servirá de los recursos usados por Feliciano de Silva en el Amadís de Grecia: el triángulo amoroso, los celos, el travestismo, la muerte y el retiro a un monasterio. La tarea de Cervantes consistirá en transformar a una virgo bellatrix —o una doncella guerrera— de libro de caballerías en una nyerra catalana. El resultado de la mezcla: Claudia Jerónima.
Alabanza y vituperio en el Persiles, I, 16: Polidoro Virgilio como posible fuente paremiológica
Authors: Alarcos Miguel
Published: December 2019

La réplica de Arnaldo a Clodio (Persiles, I, 16) compone un deliberado juego con las nociones de ‘alabanza’ y ‘vituperio’ y sus relaciones con determinados conceptos axiológicos. Por otra parte, el contenido global que arroja todo este diseño textual, ironiza especialmente con el éthos de Clodio y su conducta ulterior en la trama. Las singulares características del pasaje pudieran haberse inspirado en proverbios latinos, habida cuenta de los repertorios paremiológicos de Polidoro Virgilio (1498) y Erasmo (1500), que implantaron durante el Renacimiento un floreciente género de exégesis. Pues bien, el presente artículo, tras un bosquejo de esta clase de influjo en el Persiles y de su desarrollo cervantista, trata de explicar la originalidad de 1, 16, a tenor de la posible influencia de 3 adagios sacros «polidorianos» (los n.os 474, 477 y 478), estableciéndose una jerarquía entre los hipotextos, ya que cada uno aporta su particular grado de elaboración al pasaje.
El crédito del yo en el Persiles
Authors: Davenport Randi Lise
Published: December 2019

Este artículo documenta y analiza el uso del vocablo ‘crédito’ y sus derivaciones en el Persiles. Se presenta la hipótesis de que el uso frecuente y sofisticado de este vocablo en la última novela cervantina se podría relacionar con la constitución del sujeto y las construcciones del yo en la temprana Edad Moderna europea. Primero se ofrece un panorama diacrónico y temático del uso de este vocablo entre 1500-1750, señalando su auge en la época de Cervantes y un notable descenso hacia finales del Siglo de Oro. A continuación, se examina cómo el héroe de la novela cervantina se constituye y construye relacionándose con los demás personajes mediante el vocablo clave ‘crédito’ y sus derivaciones. Concluimos que el autor aprovecha este vocablo para con sus personajes precisamente porque viene cargado de sentidos múltiples de campos discursivos de acusada actualidad en su época, como el de la religión y el de la economía.
Reseñas de prensa: fuente para el estudio de la recepción de Cervantes en ediciones y traducciones británicas del siglo XVIII
Authors: Amenedo Costa Mónica
Published: December 2019

En el siglo XVIII, la prensa literaria inglesa ofrecía al lector valoraciones críticas sobre las novedades editoriales que salían al mercado. Esta labor periodística, que proporciona una visión sobre la recepción de obras y autores concretos, se ha empleado en este trabajo para estudiar la huella de Miguel de Cervantes en la tradición literaria inglesa en aquella centuria. Desde esta perspectiva, se ha llevado a cabo una recopilación de textos publicados en las revistas especializadas en la revisión de obras impresas The Monthly Review (1749-1845) y The Critical Review (1756-1817), poniendo el foco en los juicios de valor emitidos sobre las traducciones y ediciones de la obra cervantina. El propósito ha sido evaluar la recepción de estos trabajos, así como dar visibilidad al discurso que se articuló en torno a la figura de Cervantes y su producción literaria.
“Como si Los Amantes y Garín fueran rusos”: los motivos del fracaso de la ópera nacional en España
Authors: López Gómez Francisco Manuel
Published: December 2019

Las recientes investigaciones, a través del análisis de partituras del siglo XIX hasta hoy olvidadas, han puesto en valor algunos de los trabajos operísticos de los compositores españoles más destacados, lo cual no ha hecho más que sorprender a la comunidad musicológica, que no termina de comprender por qué estas obras nunca llegaron a implantarse dentro del repertorio canónico operístico nacional. En este artículo, partiremos de los análisis existentes de las óperas, reflexionaremos sobre el contexto en que se crearon y tomaremos en consideración las fuentes escritas coetáneas, para conocer la opinión de la crítica y el público y llegar a conclusiones factibles sobre la recepción de este género, lo cual nos permitirá establecer los motivos que impidieron el desarrollo de la ópera en España.
