Authors: Steinwender Gernot , Shajari Mehdi , Mayer Wolfgang J. , Kook Daniel , Ardjomand Navid , Vidic Bertram , Kohnen Thomas , Wedrich Andreas 
Published: July 2018

PURPOSE:
To evaluate the possible impact of a displaced corneal apex (point of maximum curvature) on visual results and tomographic parameters after small incision lenticule extraction (SMILE).

METHODS:
In this retrospective evaluation, eyes with uncomplicated SMILE for myopia correction were classified in two groups based on their preoperative distance between the corneal apex and corneal vertex (corneal intercept with the patient's line of sight) of 1 mm or greater (large A-V distance) or less than 1 mm (small A-V distance). All surgeries were performed during the early learning curve of two surgeons. Visual outcome parameters included uncorrected (UDVA) and corrected (CDVA) distance visual acuity, manifest refractive spherical equivalent (MRSE), and refractive astigmatism 3 months postoperatively. Scheimpflug-derived tomographic outcome parameters included mean keratometry value, root mean square higher order aberrations (RMS HOAs), and optical zone decentration.

RESULTS:

The study comprised 94 eyes of 48 patients: 44 eyes in the large A-V distance group and 50 eyes in the small A-V distance group. Preoperative and postoperative RMS HOAs were significantly higher in the large A-V distance group than in the small A-V distance group (
P
= .002 and .008, respectively). Postoperative CDVA was significantly better in the small A-V distance group (
P
= .014). There were no statistically significant differences in postoperative UDVA, MRSE, refractive astigmatism, mean keratometry value, and optical zone decentration.

CONCLUSIONS:
After SMILE, CDVA was significantly worse in eyes with a preoperatively displaced corneal apex compared to eyes with a more central corneal apex. However, good visual results were achieved in both groups.

Authors: Castro José J. , Ortiz Carolina , Jiménez José R. , Ortiz-Peregrina Sonia , Casares-López Miriam 
Published: July 2018

PURPOSE:
To analyze stereoscopic vision under a broad range of experimental conditions simulating small-aperture corneal inlay and monovision conditions.

METHODS:
A total of 10 patients participated in the study. The anisocoria generated by corneal inlays was simulated by using a small-aperture contact lens fitted on the non-dominant eye. Visual acuity, contrast sensitivity function, visual discrimination capacity (halo perception), and stereoacuity tests were performed under natural conditions or when the non-dominant eye wore the small-aperture contact lens under two conditions: induced anisocoria and induced anisocoria combined with monovision (using two add-powers: +0.75 and +1.25 diopters [D]). Stereoscopic vision and binocular summation were analyzed under those experimental conditions and for far, intermediate, and near vision.

RESULTS:
The results showed a deterioration in stereoacuity with respect to natural conditions, being significant mainly for near and intermediate distances. Results with other visual functions showed a deterioration of the binocular summation and therefore of visual performance, although not in a generalized way for all distances. Binocular visual acuity under the conditions that used the small-aperture contact lens was comparable to that of the natural eye.

CONCLUSIONS:
The deterioration of stereopsis and other binocular functions found in this study may be acceptable for patients who had this surgical technique because it is similar to the deterioration found in other surgical procedures of emmetropization.

Published: July 2018

PURPOSE:
To investigate lenticule decentration following small incision lenticule extraction (SMILE) via the subjective patient fixation method or triple marking centration method and compare inductions of corneal higher order aberrations (HOAs) between the two methods.

METHODS:
This study analyzed decentration values obtained from the Keratron Scout (Optikon, Rome, Italy) tangential topography difference map of 110 eyes (110 patients) undergoing SMILE with the subjective patient fixation method (n = 55) or triple marking centration method (n = 55). Root mean square values of total HOAs, 3rd order coma aberration, and 4th order spherical aberration, as well as individual coefficients for vertical and horizontal coma, were measured preoperatively and 3 months postoperatively. Relationships between the magnitudes of decentration and induced corneal HOAs were assessed.

RESULTS:

There were significant differences in horizontal decentered displacement (
P
= .048), vertical decentered displacement (
P
= .002), and total decentered displacement (
P
= .001) between the two groups. Total HOAs, coma, vertical coma, and spherical aberration significantly increased in the subjective patient fixation method (all
P
< .001), whereas total HOAs (
P
= .002) and vertical coma (
P
= .005) increased in the triple marking centration method. Induction of total HOAs (mean values: 0.13 vs 0.07;
P
= .026), coma (0.09 vs 0.03;
P
= .032), and spherical aberration (0.08 vs 0.02;
P
= .013) was significantly greater in the subjective patient fixation method than in the triple marking centration method. Association between the total decentered displacement and induced vertical coma (
P
= .006) or induced spherical aberration (
P
= .018) was significant in the subjective patient fixation method.

CONCLUSIONS:

SMILE with the triple marking centration method can yield improved treatment centration and smaller induction of total HOAs, coma, and spherical aberrations.

Rotational Stability and Visual Outcomes of V4c Toric Phakic Intraocular Lenses
Authors: Lee Hun , Kang David Sung Yong , Choi Jin Young , Ha Byoung Jin , Kim Eung Kweon , Seo Kyoung Yul , Kim Tae-im 
Published: July 2018

PURPOSE:
To investigate the clinical outcomes and rotational stability following implantation of V4c toric implantable collamer lenses (ICLs) (STAAR Surgical Company, Monrovia, CA) and to analyze the factors that influence rotational stability.

METHODS:
In this prospective observational case series, the authors analyzed the visual outcomes and rotational stability in 52 eyes of 52 patients immediately and 3 and 6 months after implantation. Postoperative rotation was defined as the angle between the adjusted axis and alignment axis. Central vaulting of the ICL was measured in a non-accommodative state using Visante optical coherence tomography (Carl Zeiss Meditec, Jena, Germany). Vector analysis of refractive astigmatism was performed. Regression analysis was used to investigate the association between the degree of rotation 6 months postoperatively and the associated variables.

RESULTS:

The mean efficacy index and safety index 6 months postoperatively were 1.35 ± 0.19 and 1.38 ± 0.22, respectively. In vector analysis, the magnitude of error was −0.20 diopters (D), indicating slight undercorrection. Absolute degree of rotation was 2.81° ± 1.87° immediately after the operation and 3.75° ± 2.92° and 3.87° ± 3.07° at 3 and 6 months postoperatively, respectively (
P
= .009). Bonferroni-adjusted post-hoc comparison showed that the absolute degree of rotation immediately after the operation was significantly smaller than that after 3 (
P
= .043) and 6 (
P
= .023) months, with barely any change after 3 months. No explanatory variable relevant to the absolute degree of rotation was discovered.

CONCLUSIONS:
The V4c toric ICL is predictable, safe, and effective in correcting low and high levels of astigmatism, showing relatively good postoperative rotational stability.

The influence of long-term changes in canopy structure on rainfall interception loss: a case study in Speulderbos, the Netherlands
Authors: Cisneros Vaca César , van der Tol Christiaan , Ghimire Chandra Prasad 
Published: July 2018

Abstract. The evaporation of intercepted water by forests is a significant
contributor to both the water and energy budget of the Earth. In many
studies, a discrepancy in the water and energy budget is found: the energy
that is needed for evaporation is larger than the available energy supplied
by net radiation. In this study, we analyse the water and energy budget of a
mature Douglas fir stand in the Netherlands, for the two growing seasons
of 2015 and 2016. Based on the wet-canopy water balance equation for these
two growing seasons, derived interception losses were estimated to be 37 and
39 % of gross rainfall, respectively. We further scrutinized eddy-covariance energy balance data from these two
consecutive growing seasons and found the average evaporation rate during
wet-canopy conditions was 0.20 mm h−1. The source of energy for this
wet-canopy evaporation was net radiation (35 %), a negative sensible heat
flux (45 %), and a negative energy storage change (15 %). This confirms
that the energy for wet-canopy evaporation is extracted from the atmosphere
as well as the biomass. Moreover, the measured interception loss at the forest was similar to that
measured at the same site years before (I = 38 %), when the forest
was younger (29 years old, vs. 55 years old in 2015). At that time, the
forest was denser and had a higher canopy storage capacity (2.4 mm then
vs. 1.90 mm in 2015), but the aerodynamic conductance was lower (0.065 m s−1
then vs. 0.105 m s−1 in 2015), and therefore past evaporation
rates were lower than evaporation rates found in the present study (0.077 mm h−1
vs. 0.20 mm h−1 in 2015). Our findings emphasize the importance
of quantifying downward sensible heat flux and heat release from canopy
biomass in tall forest in order to improve the quantification of evaporative
fluxes in wet canopies.
Brief communication: Co-seismic displacement on 26 and 30 October 2016 (Mw = 5.9 and 6.5) – earthquakes in central Italy from the analysis of a local GNSS network

Published: July 2018

Abstract. On 24 August 2016 a strong earthquake (Mw = 6.0) affected central Italy and an intense seismic sequence started. Field observations, DInSAR (Differential INterferometry Synthetic-Aperture Radar) analyses and preliminary focal mechanisms, as well as the distribution of aftershocks, suggested the reactivation of the northern sector of the Laga fault, the southern part of which was already rebooted during the 2009 L'Aquila sequence, and of the southern segment of the Mt Vettore fault system (MVFS). Based on this preliminary information and following the stress-triggering concept (Stein, 1999; Steacy et al., 2005), we tentatively identified a potential fault zone that is very vulnerable to future seismic events just north of the earlier epicentral area. Accordingly, we planned a local geodetic network consisting of five new GNSS (Global Navigation Satellite System) stations located a few kilometres away from both sides of the MVFS. This network was devoted to working out, at least partially but in some detail, the possible northward propagation of the crustal network ruptures. The building of the stations and a first set of measurements were carried out during a first campaign (30 September and 2 October 2016). On 26 October 2016, immediately north of the epicentral area of the 24 August event, another earthquake (Mw = 5.9) occurred, followed 4 days later (30 October) by the main shock (Mw = 6.5) of the whole 2016 summer–autumn seismic sequence. Our local geodetic network was fully affected by the new events and therefore we performed a second campaign soon after (11–13 November 2016). In this brief note, we provide the results of our geodetic measurements that registered the co-seismic and immediately post-seismic deformation of the two major October shocks, documenting in some detail the surface deformation close to the fault trace. We also compare our results with the available surface deformation field of the broader area, obtained on the basis of the DInSAR technique, and show an overall good fit.
Impacts of the low-level jet's negative wind shear on the wind turbine
Authors: Gutierrez Walter , Ruiz-Columbie Arquimedes , Tutkun Murat , Castillo Luciano 
Published: July 2018

Abstract. Nocturnal low-level jets (LLJs) are defined as relative maxima in the vertical profile of the horizontal wind speed at the top of the stable boundary layer. Such peaks constitute major power resources for wind turbines. However, a wind speed maximum implies a transition from positive wind shears below the peak to negative ones above. The effect that such a transition has on wind turbines has not been thoroughly studied.This research study employed a methodical approach to the study of negative wind shear's impacts on wind turbines. Up to now, the presence of negative shears inside the turbine's rotor in relation to the presence of positive shears has been largely ignored. A parameter has been proposed to quantify that presence in future studies of LLJ–wind-turbine interactions. Simulations were performed using the NREL aeroelastic simulator FAST code. Rather than using synthetic profiles to generate the wind data, all simulations were based on real data captured at the high frequency of 50 Hz, which allowed us to perform the analysis of a turbine's impacts with real-life, small scales of wind motions.It was found that the presence of negative wind shears at the height of the turbine's rotor appeared to exert a positive impact on reducing the motions of the nacelle and the tower in every direction, with oscillations reaching a minimum when negative shears covered the turbine swept area completely. Only the tower wobbling in the spanwise direction was amplified by the negative shears; however, this occurred at the tower's slower velocities and accelerations. The forces and moments were also reduced by the negative shears. The aforementioned impacts were less beneficial in the rotating parts, such as the blades and the shafts. Finally, the variance in power production was also reduced. These findings can be very important for the next generation of wind turbines as they reach deeper into LLJ's typical heights.The study demonstrated that the presence of negative shears is significant in reducing the loading on wind turbines. A major conclusion of this study is that the wind turbines of the future should probably be designed with the aim of reaching the top of the nightly boundary layer more often and therefore the altitudes where negative shears are more frequent. Doing so will help to reduce the positive shear's associated damage and to capture the significant LLJ energy.

Aplicação da análise isotópica de composto específico (Técnica CSIA) em perícias ambientais para distinguir diferentes fontes de contaminação
Authors: Teixeira Luiz Guilherme Poggio , Abreu Ana Elisa Silva de 
Published: July 2018

A Análise Isotópica de Composto Específico (CSIA, do inglês Compound Specific Isotope Analysis) é uma técnica analítica para determinar razões de isótopos estáveis com ampla aplicação no campo das ciências forenses, incluindo, drogas ilícitas, explosivos, doping de atletas e, mais recentemente, no estudo da contaminação da água subterrânea. O presente artigo discorre sobre o emprego da referida técnica como uma importante ferramenta para diferenciar plumas distintas de contaminantes em estudos de perícia ambiental, enfatizando-se aqui compostos organoclorados. Com base em revisão bibliográfica são apresentados os princípios básicos da técnica, os processos naturais que causam o fracionamento isotópico e casos reais onde a técnica CSIA foi empregada. Tendo como base o modelo hidrogeológico/hidroquímico, a conjugação desta técnica, especialmente quando empregada com isótopos de mais de um elemento numa mesma área, aliada aos métodos tradicionais como análise físico-química e modelagem computacional, aumenta significativamente as chances de sucesso para distinção da origem dos contaminantes e imputação de responsabilidades em contendas judiciais.
Colita en contexto: fotografía y feminismo durante la transición española.
Authors: Rosón Villena María 
Published: July 2018

El trabajo que desarrolló la fotógrafa catalana Colita (Barcelona, 1940) durante la década de los setenta fue aliado del movimiento feminista que se recompuso en el Estado español tras la muerte de Franco. En este artculo estudiaremos sus práctcas fotográfcas al respecto, aquellas que visibilizaron las demandas más importantes del feminismo español del momento: su trabajo para la revista <em>Vindicación feminista</em> (1976- 1979 y el fotolibro <em>Antfémina</em> (Editora Nacional, 1977), que hizo en colaboración con María Aurèlia Capmany. En segundo lugar atenderemos a la fotografa erótca que también desarrolló Colita durante estos años, una producción más problemátca a la luz de las propuestas feministas del momento. Por un lado estas politzaron el placer sexual pero por otro se manifestaron en contra de las imágenes del “destape”, por cosifcar el cuerpo desnudo de las mujeres. Sin embargo, este trabajo permite una lectura <em>queer</em> o al menos presenta una estructura disidente con el deseo o la mirada heterosexual.

Agricultura y Alimentación en el México Prehispánico y siglo XVI/Agriculture and Food in Pre-Hispanic Mexico and the 16th Century.
Authors: Sánchez Verín Carlos Arturo Giordano 
Published: July 2018

El inicio de la agricultura en el Continente Americano inició en lo que actualmente se conoce como México. A partir de la gran diversidad geográfica fueron surgiendo diferentes productos y una especialización en su siembra y cuidados, a fin de obtener el mejor rendimiento de los mismos. Fue necesario conocer el clima, las calidades de la tierra y el tiempo a fin de establecer los ciclos agrícolas que dieron como resiltado una gran variedad de plantas que representaron la base de la alimentación de los pueblos mesoamericanos.La llamada Conquista de México trajo consigo nuevos métodos agrícolas, herramientas, animales de tiro y carga y, por supuesto, una gran cantidad de plantas que muy pronto se adaptaron a la geografía de la Nueva España. ABSTRACTThe emergence of agriculture in Mexico was a factor of great relevance, which allowed the development of Mesoamerican cultures more than three thousand years of history. The geographical location of the different ethnic groups that inhabited this region allowed the cultivation of a wide variety of plants, such as corn, beans, pumpkin and chili, basic products in the Mesoamerican diet, as well as other products were developed according to the geographic characteristics and climatological, such as cocoa, from which chocolate is obtained, and even vanilla, being appreciated all over the world. Those original products were mixed with those brought by Europeans in the sixteenth century and this gave rise to Mexican cuisine, which in 2010 was declared an Intangible Cultural Heritage of Humanity by the United Nations Educational, Scientific and Cultural Organization (UNESCO).Key words: Mesoamerican cultures, Mexican gastronomy, Intangible Cultural Heritage of Humanity of the United Nations Educational, Scientific and Cultural Organization (UNESCO)
