Published: September 2019

Apart from being used for the treatment of malaria fevers, mono-herbal preparation of Ugandan Phyllanthus amarus is widely by local communities in central Uganda, for treatment of bacterial dysentery. However, efficacy studies regarding the mono-herbal extracts of the Ugandan Phyllanthus amarus against Shigella dysenteriae is lacking. The present study was aimed at determined the antibacterial activity of aqueous ethanol crude extracts of whole plant of Phyllanthus amarus against Shigella dysenteriae. Whole plant of Phyllanthus amarus was collected from Wakiso district central of Uganda. Different concentrations (128µg/ml, 256µg/mL-1 and 512µg/ mL-1) of the ethanol crude extract of whole plant of Phyllanthus amarus were tested against Shigella dysenteriae using agar well diffusion method. Minimum inhibitory concentration (MIC) was determined using broth tube dilution method while Minimum bactericidal concentration (MBC) was determined by culture method. The results of this study showed that, Shigella dysenteriae was sensitive to different concentrations (128µg/ mL-1, 256µg/ mL-1and 512µg/ mL-1) of ethanol crude extract of whole plant of Phyllanthus amarus possessed antibacterial against Shigella dysenteriae with mean and standard error mean zone of inhibition ranging from 11.5±0.5 to 13.5±0.5mm, while the positive control had mean and standard error mean zone of inhibition 24.5±0.5mm. The MIC and MBC of the ethanol crude extract of whole plant of Phyllanthus amarus against Shigella dysenteriae was found to be 32µg/ml and 64µg/ml respectively. This study found that the whole plant of phyllanthus amarus of ethanol crude extract was active against Shigella dysenterie. Further study should be carried out test whole plant Phyllanthus amarus crude extract on different microorganisms that cause dysentery to find out its activity against them and spectrum, determine lead compound in the whole plant Phyllanthus amarus crude extract responsible for the anti-microbial activity against Shigella dysenteriae and also determine the mechanism of action by which this plant crude extract inhibits Shigella dysenteriae.

Published: September 2019

A study to determine the occurrence of Yersinia enterocolitica and Citrobacter freundii, two potential human pathogens in the throats of tropical pigs of Grenada origin and the antimicrobial pattern of the isolates was carried out. During a period of 30 days (15 September 2017 to 15 October 2017), throat swabs from a total of 97 weaned pigs were sampled to isolate and characterize Y. enterocolitica by serotyping and resistance testing, and to isolates C. freundii. Of the pigs tested, four (4.1%) pigs were positive for Y. enterocolitica. The four Yersinia-positive pigs included one (2.4%) of 41 male pigs and three (5.4%) of 56 female pigs. There were no significant differences between the proportions of Yersinia-positive male and female pigs (p = 0.8437). Of these four Yersinia-positive pigs, two were mixed with C. freundii, one had slight contamination, and the other was pure. All belonged to serotype 0:9. There were 31 pigs positive for C. freundii, and all showed mixed growth. Antimicrobial susceptibility tests against 14 drugs indicated that all isolates of Y. enterocolitica were susceptible to third-generation cephalosporins and fluoroquinolones, two classes of antimicrobials recommended for the treatment of Y. enterocolitica infection in humans.
Visual and Refractive Outcomes of LASIK With the SCHWIND ESIRIS and WaveLight ALLEGRETTO WAVE Eye-Q Excimer Lasers: A Prospective, Contralateral Study
Authors: Mearza Ali A. , Muhtaseb Mohammed , Aslanides Ioannis M. 
Published: September 2019

Purpose
To compare the safety, efficacy, and predictability of LASIK with the SCHWIND ESIRIS and WaveLight ALLEGRETTO WAVE Eye-Q excimer laser platforms.

Methods
This prospective study comprised 44 eyes of 22 consecutive patients who were treated with LASIK using the Moria M2 microkeratome. One eye was treated with the SCHWIND ESIRIS laser and the fellow eye treated with the WaveLight ALLEGRETTO WAVE Eye-Q laser. All eyes operated with the SCHWIND ESIRIS were treated with standard aspheric ablation, whereas the eyes operated with the WaveLight ALLEGRETTO WAVE Eye-Q received treatment with three different ablation types according to the common practice at our clinic. Outcome measures were uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), manifest refraction, and proximity to target refraction at 6-month follow-up.

Results

At 6 months postoperative, mean decimal UCVA was 0.96±0.22 (range: 0.3 to 1.2) for ESIRIS eyes and 0.98±0.17 (range: 0.6 to 1.2) for ALLEGRETTO eyes (
P
=.57). Mean postoperative spherical equivalent refraction was −0.02±0.28 diopters (D) (range: −0.75 to +0.75 D) for ESIRIS eyes and 0.11±0.91 D (range: ±1.00 to ±3.88 D) for ALLEGRETTO eyes (
P
=.49). Of the ESIRIS eyes, 20/22 (91%) were within ±1.00 D of target refraction and 20/22 (91%) were within ±0.50 D of target refraction. Of the ALLEGRETTO eyes, 20/22 (91%) and 19/22 (86%) were within ±1.00 D and ±0.50 D, respectively, of target refraction. No patient lost ⩾2 lines of BSCVA in either group.

Conclusions

No differences were seen in safety and efficacy outcome parameters between the SCHWIND ESIRIS and WaveLight ALLEGRETTO WAVE Eye-Q excimer lasers when used according to a previously established treatment algorithm at our clinic in the treatment of refractive error. [

Estimation of Posterior Corneal Power for IOL Calculation After Myopic LASIK
Authors: Srivannaboon Sabong , Rakpanichmanee Thanapat , Cheng Arthur C.K. , Fam Han-Bor 
Published: September 2019

Purpose
To estimate the posterior corneal power for intraocular lens (IOL) calculation after myopic LASIK.

Methods
A retrospective study of 50 patients (92 eyes) who underwent uneventful myopic LASIK was conducted. Pre- and postoperative data (12 months) were collected including refraction and Orbscan II (Bausch & Lomb) for simulated keratometry (Sim K), central corneal thickness, and posterior corneal power. Statistical analysis was performed to determine the correlation between the postoperative posterior corneal power and other variables. An empirical formula was generated to predict the postoperative posterior corneal power. The net corneal power was calculated based on the new formula and Gaussian optics formula in an additional 31 eyes that underwent myopic LASIK and compared to the Orbscan total optical power map. The net corneal power was retrospectively applied to calculate the IOL power in an additional 10 patients who underwent cataract extraction after myopic LASIK. The back-calculation for emmetropic IOL power was performed and compared to the IOL power derived from the net corneal power.

Results

By using multiple linear regression, a formula to predict postoperative posterior corneal power can be computed from postoperative Sim K, central corneal thickness, and the amount of myopia treated with R
2
of 0.63 (standard error = 0.25) (
P
<.05). The net corneal power was highly correlated to the total optical power (R
2
=0.96); no statistically significant difference (paired
t
test) was noted (
P
>.05). The error of the IOL power derived from the net corneal power was −0.30±0.20 diopters.

Conclusions

Corneal power after myopic LASIK can be estimated using postoperative Sim K, central corneal thickness, and the amount of myopia treated, which can be used for the assessment of IOL power after myopic LASIK. [

Adaptive Calibration of Dynamic Accommodation—Implications for Accommodating Intraocular Lenses
Authors: Schor Clifton M. , Bharadwaj Shrikant R. 
Published: September 2019

Purpose
When the aging lens is replaced with prosthetic accommodating intraocular lenses (IOLs), with effective viscoelasticities different from those of the natural lens, mismatches could arise between the neural control of accommodation and the biomechanical properties of the new lens. These mismatches could lead to either unstable oscillations or sluggishness of dynamic accommodation. Using computer simulations, we investigated whether optimal accommodative responses could be restored through recalibration of the neural control of accommodation. Using human experiments, we also investigated whether the accommodative system has the capacity for adaptive recalibration in response to changes in lens biomechanics.

Methods
Dynamic performance of two accommodating IOL prototypes was simulated for a 45-year-old accommodative system, before and after neural recalibration, using a dynamic model of accommodation. Accommodating IOL I, a prototype for an injectable accommodating IOL, was less stiff and less viscous than the natural 45-year-old lens. Accommodating IOL II, a prototype for a translating accommodating IOL, was less stiff and more viscous than the natural 45-year-old lens. Short-term adaptive recalibration of dynamic accommodation was stimulated using a double-step adaptation paradigm that optically induced changes in neuromuscular effort mimicking responses to changes in lens biomechanics.

Results
Model simulations indicate that the unstable oscillations or sluggishness of dynamic accommodation resulting from mismatches between neural control and lens biomechanics might be restored through neural recalibration.

Conclusions

Empirical measures reveal that the accommodative system is capable of adaptive recalibration in response to optical loads that simulate effects of changing lens biomechanics. [

Outcomes of Hyperopic LASIK With the NIDEK NAVEX Platform Centered on the Visual Axis or Line of Sight
Authors: Kermani Omid , Oberheide Uwe , Schmiedt Karl , Gerten Georg , Bains Harkaran S. 
Published: September 2019

Purpose:
To report refractive outcomes of hyperopic LASIK with automated centration on the visual axis compared with centration on the line of sight (LOS).

Methods:
The NIDEK Advanced Vision Excimer Laser platform (NAVEX) was used to treat 181 hyperopic eyes with centration on the LOS (LOS group) and 64 hyperopic eyes with centration on the visual axis (visual axis group). The coordinates of the visual axis were digitally transferred to the excimer laser system based on the positional relationship between the LOS and the coaxially sighted corneal light reflex. All eyes were treated with a 6.5-mm optical zone and 9.0-mm transition zone. Three-month postoperative outcomes were retrospectively analyzed.

Results:
The preoperative manifest refraction spherical equivalent (MRSE) was +2.57±1.26 diopters (D) (range: 0.13 to 5.63 D) in the visual axis group and +2.46±1.32 D (range: 0.38 to 5.63 D) in the LOS group. The postoperative MRSE was +0.29±0.70 D (range: −1.00 to 1.75 D) in the visual axis group and +0.19±0.57 D (range: −0.75 to 1.75 D) in the LOS group. Postoperatively, 81% (38/47) of eyes in the visual axis group and 64% (74/116) of eyes in the LOS group were ±0.50 D. In the visual axis group, 91% (44/52) of eyes and 92% (102/109) of eyes in the LOS group maintained best spectacle-corrected visual acuity within one line compared with preoperatively.

Conclusions:

Initial experience with hyperopic LASIK centered on the visual axis indicated safe and predictable outcomes. [

Steroid-induced Interface Fluid Syndrome After LASIK
Authors: Calleja Tomás Moya , Ferrer Yolanda Iribarne , Jorge Alicia Sanz , Fernández Sergio Sedó 
Published: September 2019

Purpose:
To report ocular manifestations of eyes that developed interface fluid syndrome secondary to steroid-induced elevation of intraocular pressure (IOP) after LASIK. The patients presented with similiar characteristics of diffuse lamellar keratitis (DLK).

Methods:
Retrospective evaluation of four eyes of three patients with loss of vision, fluid in the lamellar interface, and IOP and topographic changes due to prolonged treatment with topical corticosteroids after LASIK.

Results:
Slit-lamp microscopy revealed an optically clear fluid-filled space between the flap and stromal bed. After early diagnosis, treatment with topical corticosteroids was stopped, resulting in quick and progressive cessation of symptoms.

Conclusions:

A steroid-induced rise in IOP after LASIK can cause transudation of aqueous fluid across the endothelium that collects in the flap interface. It is important to make an early differential diagnosis of interface fluid syndrome in DLK-suspected cases, as continued treatment with corticosteroids can produce serious visual loss. [

Multizone LASIK With Peripheral Near Zone for Correction of Presbyopia in Myopic and Hyperopic Eyes: 1-year Results
Authors: El Danasoury Alaa M. , Gamaly Tamer O. , Hantera Mohamed 
Published: September 2019

Purpose:
To investigate the refractive outcomes of multifocal LASIK to create a center far, peripheral near zone in presbyopes.

Methods:
This prospective study using LASIK with a center far, peripheral near ablation algorithm comprised 68 eyes of 34 hyperopes and 78 eyes of 39 myopes. Mean patient age was 49±5.60 years for hyperopes and 46.0±3.80 years for myopes. Mean baseline manifest refraction spherical equivalent was +1.76±0.96 diopters (D) in hyperopes and −3.06±1.73 D in myopes. The mean baseline addition was +1.94±0.40 D in hyper-opes and +1.67±0.44 D in myopes. One-year postoperative outcomes are reported.

Results:

The mean postoperative spherical equivalent refraction was −0.10±0.55 D in hyperopes and −0.48±0.51 D in myopes. Two percent of eyes in each group lost two lines of best spectacle-corrected visual acuity. With the distance correction in place, 20/40 or better near uncorrected visual acuity (UCVA) (Sloan acuity) was achieved in 33% of hyperopes and 36% of myopes. A statistically significant difference was noted in postoperative near visual acuity measured by the Sloan and Rosenbaum charts (
P
<.05). Fifty-four percent of hyperopes and 48% of myopes were satisfied or very satisfied with their postoperative near UCVA.

Conclusions:

Multifocal LASIK to create a center far and peripheral near zone is safe and allows half of the patients to achieve spectacle independence. A peripheral near zone was only created in myopic treatments. [

Authors: Liu Yue , Li Yuanxun , Lu Yongcheng , Su Hua , Tao Zhihua , Chen Mingzhou , Chen Daming 
Published: September 2019

Abstract
Because of good thermal, electrical, and mechanical properties, low-temperature cofired ceramic (LTCC) has shown great potential in microelectronic applications. One of the most promising directions of LTCC technology development are integrating and packing sensors. In this article, a wireless passive capacitive pressure sensor operating in the MHz range based on cofiring of heterogeneous materials with LTCC technology is proposed, and the design, simulation, and fabrication of the sensor are demonstrated and discussed. It consists of a circular spiral inductor and a capacitor of two electrodes separated by a glass medium. Furthermore, a unique process of cofiring of heterogeneous materials was introduced to avoid deformation of the capacitive embedded cavity during lamination or sintering. The results show that the inductance of the inductor and the capacitance of the capacitor embedded in the sensor are .28 μH and 16.80 pF, respectively. The novel sensor has a sensitivity of approximately 847 Hz/MPa within the pressure range from atmospheric pressure to 100 MPa.

Published: September 2019

Los tributos, además de instrumentos para la captación de los recursos necesarios para el sostenimiento de gastos públicos se erijen como herramientas de política económica y social cuya finalidad consiste en atender a realización de los principios contenidos en la Constitución. El espíritu del Estado social y democrático de Derecho que propugna en su artículo primero como valores superiores del ordenamiento jurídico la libertad, la justicia, la igualdad y el pluralismo político, y que se construye en el Capítulo Tercero de su Título I, coincide con el de la mayoría de los Objetivos de Desarrollo Sostenible contenidos en el documento “Transformando nuestro mundo: la Agenda 2030 para el Desarrollo Sostenible” adoptado en el marco de Naciones Unidas en 2015. Esta comunicación analiza el papel de la asignatura Derecho Financiero y Tributario en la incorporación de esos ODS, por un lado, a través de la puesta en relevancia del papel de los tributos como herramientas de política económica y social, subrayando no sólo la relevancia de los impuestos más generalistas sino también de los de corte extrafiscal, y, por otro, empoderando y movilizando al alumnado proporcionándole una formación académica para implementar soluciones ODS a través de los conocimientos y habilidades adquiridos.

Published: September 2019

En una de las prácticas de la asignatura Redes eléctricas inteligentes del Máster Universitario en Tecnología Energética para Desarrollo Sostenible de la UPV, se pide realizar el diseño de una microrred con un sistema solar PV y almacenamiento en baterías. Actualmente para realizar dicho diseño existen programas informáticos utilizados a nivel empresarial, como el PVSyst o el SAM, para el caso del diseño o Homer para llevar a cabo el análisis económico. Estas herramientas, aunque útiles, tienen un coste elevado y, como es habitual en programas informáticos, tienen limitaciones a la hora de modificar el método a utilizar. Al introducir los cálculos en MS Excel por sí mismo, comparado con softwares, se mejora el aprendizaje de los estudiantes. También se podría realizar el diseño de forma manual, pero es un procedimiento muy laborioso y se pueden cometer errores durante la realización de los cálculos. En este documento se explica y utiliza una metodología innovadora para realizar el diseño de un sistema de generación de energía de 12 kW, a través de una herramienta viable y utilizada por los estudiantes durante sus estudios como es el caso de Microsoft Excel. Como resultado de aplicar la innovación, el estudiante obtiene el diseño del sistema propuesto, el cual incluye la selección y el dimensionamiento de los paneles solares, inversores y baterías, así como la integración de todos los componentes en el sistema. Mediante este diseño el estudiante desarrolla las competencias transversales UPV 1 a 5 y 9.
Dibujo para todos. Prácticas pedagógicas en el grado en Artes Digitales: pensamiento abstracto, formas geométricas básicas y sistemas de retícula
Authors: Rejas del Hoyo Miguel A. , Báscones Reina Noelia 
Published: September 2019

Todo proyecto de diseño requiere de una concepción basada en la metodología proyectual que parte del esbozo como herramienta para la configuración de ideas a partir de elementos esenciales de la forma tales como la línea, el círculo o el cuadrado. Todas estas características se desarrollan mediante la observación y el dibujo, y nos ayudan a definir la estructura, dirección, peso visual, movimiento o composición y por lo tanto forman parte de la estructura reticular propia del diseño gráfico y en general de todas aquellas disciplinas en las que intervine la práctica creativa.
Por este motivo, el presente estudio plantea una reflexión sobre la necesidad de establecer nuevas prácticas pedagógicas dentro de los estudios de grado universitario vinculados a la formación en disciplinas como el diseño, la comunicación o la publicidad.
Para ello se lleva a cabo un recorrido por las nuevas pedagogías surgidas a finales del S. XIX y que fueron tan influyentes en la formación de diseñadores y artistas de Vanguardia y sobre las que se apoyan las bases estéticas de De Stijl y Bauhaus que a su vez conforman el principio de todo un estilo hacia la abstracción que marcó el cambio de paradigma hacia nuevos enfoques en el arte y el diseño del siglo XX y XXI. Este recorrido se ve reflejado en el análisis de un caso de estudio en el que se ponen en práctica estrategias de aprendizaje inspiradas tanto en las pedagogías Bauhaus como en el modelo pedagógico de Pestalozzi, combinando el aprendizaje de herramientas digitales con la formación para el desarrollo del pensamiento abstracto a través de formas geométricas básicas y su aplicación a los sistemas de retícula.
The Apostles as the Messiah’s Kingly and Prophetic Shepherds of Jeremiah 23
Authors: Henning Bruce 
Published: September 2019

Abstract
Matthew 9:36 and 10:6 clearly echo Ezek 34 with its description of restoration as eschatological shepherding. However, this article argues that Jer 23:1–6 also warrants serious consideration, though it is rarely noticed. Activating this text in the audience’s mind casts the apostles as eschatological shepherds in conjunction with the messiah, resulting in the emphasis of their royal and prophetic functions. After establishing that Jer 23:1–6 satisfies various criteria of an allusion, Jer 23 will be examined to demonstrate that, though הָרֹעִים and ποιμένας are general terms, contextually the terms refer to eschatological rulers and prophets connected to the messiah. Last, the Gospel of Matthew, particularly the mission discourse, will be considered to see how the apostles are cast in these roles.
