Published: September 2019

Amaç: Bu çalışmanın amacı, periodontal kemikiçi defektlerin belirlenmesinde klinik ölçümler ile ortopantomograf görüntüleme (OPG) ve konik ışınlı bilgisayarlı tomografi (KIBT) ile tanı değerini değerlendirmek ve sonuçları karşılaştırarak klinikte rutin olarak teşhis ve tedaviye yardımcı olan dijital radyografilerin güvenilirliğini sorgulamaktır.Materyal ve Metod: Eskişehir Osmangazi Üniversitesi Diş Hekimliği Fakültesi Periodontoloji Anabilim Dalına Ekim 2015 - Nisan 2016 tarihleri arasında başvuran hastalardan kronik periodontitis ve agresif periodontitis teşhisi konulmuş bireyler çalışmaya dahil edilmiştir. Radyografik ölçümlerde Alveoler kret (AK) projeksiyonunun kök yüzeyine temas ettiği en üst nokta defektin tavanı, periodontal ligamentin kök yüzeyinde izlendiği en apikal kontur defektin tabanı olarak belirlenmiştir. Mine-sement birleşimi (MSB) bu ölçümler için sabit koronal referans olarak alınmıştır. Radyografik ölçümler yukarıda belirtilen çizgiler çizildikten sonra yapılmıştır. Radyografik ölçümlerden sonra, klinik ölçümler flep ameliyatı esnasında ölçülmüştür. Bulgular: Bu çalışmanın bulgularına göre anterior bölgede OPG ve KIBT iyi düzeyde klinik bulguları temsil ederken, posterior bölgede ise KIBT ile yapılan ölçümler klinik ölçümlerde mükemmel oranda korelasyon bulunmuştur. Ayrıca tüm verilerin değerlendirilmesinde KIBT klinik ölçümleri OPG’ye oranla daha iyi temsil etmektedir.Sonuç: Klinik olarak tespit edilmiş kritik kemik içi defektlerde daha kesin yargıya varabilmek ve daha radikal tedavi planlaması yapabilmek amaçlandığında KIBT’den yararlanmak daha avantajlıdır.

Even every work of arts especially in literature has their own unique story style yet its also has similarities in the idea or problems of human being. The similarities appear on their works because they share some common aspects of life which is also called as the intertextuality. Themes and motives in work of arts are similar because of the universal consciousness among the authors. And by these works Diary of a Mad Old Man by Junichiro Tanizaki, Aku by Chairil Anwar, The Jilting of Granny Weatherall by Kathrene Anne Porter and The Tinkers by Paul Harding deal with the same theme about life and death. Moreover, three main characters also in the same age, they are old people who fought their life before the death toke it away. The analysis is using qualitative method to evaluate the similarities and the differences concept of life and death and also to able to found out any correlation of each work related with the intertextuality among them

Published: September 2019

Abstract
We present moderate resolution near-infrared spectra in the H, J, and K band of M-dwarf hosts to candidate transiting exoplanets discovered by NASA’s K2 mission. We employ known empirical relationships between spectral features and physical stellar properties to measure the effective temperature, radius, metallicity, and luminosity of our sample. Out of an initial sample of 56 late-type stars in K2, we identify 35 objects as M dwarfs. For that subsample, we derive temperatures ranging from 2870 to 4187 K, radii of 0.09–0.83 R
⊙, luminosities of

, and [Fe/H] metallicities between −0.49 and 0.51 dex. We then employ the stellar properties derived from spectra, in tandem with the K2 light curves, to characterize their planets. We report 33 exoplanet candidates with orbital periods ranging from 0.19 to 21.16 days, and median radii and equilibrium temperatures of 2.3 R
⊕ and 986 K, respectively. Using planet mass–radius relationships from the literature, we identify seven exoplanets as potentially rocky, although we conclude that probably none reside in the habitable zone of their parent stars.
Hydrogen Emission in Type II White-light Solar Flares
Authors: Procházka Ondřej , Reid Aaron , Mathioudakis Mihalis 
Published: September 2019

Abstract
Type II white-light flares (WLFs) have weak Balmer line emission and no Balmer jump. We carried out a set of radiative hydrodynamic simulations to understand how the hydrogen radiative losses vary with the electron-beam parameters and more specifically with the low-energy cutoff. Our results have revealed that for low-energy beams, the excess flare Lyman emission diminishes with increasing low-energy cutoff as the energy deposited into the top chromosphere is low compared to the energy deposited into the deeper layers. Some Balmer excess emission is always present and is driven primarily by direct heating from the beam with a minor contribution from Lyman continuum backwarming. The absence of Lyman excess emission in electron-beam driven models with high low-energy cutoff is a prominent spectral signature of type II WLFs.

Abstract
We report the first measurements with sub-kiloparsec spatial resolution of strongly inverted gas-phase metallicity gradients in two dwarf galaxies at z ∼ 2. The galaxies have stellar masses ∼109

, specific star formation rate ∼20 Gyr−1, and global metallicity

(1/4 solar), assuming the strong-line calibrations of [O iii]/Hβ and [O ii]/Hβ from Maiolino et al. Their radial metallicity gradients are measured to be highly inverted, i.e., 0.122 ± 0.008 and 0.111 ± 0.017 dex kpc−1, which is hitherto unseen at such small masses in similar redshift ranges. From the Hubble Space Telescope observations of the source nebular emission and stellar continuum, we present two-dimensional spatial maps of star formation rate surface density, stellar population age, and gas fraction, which show that our galaxies are currently undergoing rapid mass assembly via disk inside-out growth. More importantly, using a simple chemical evolution model, we find that the gas fractions for different metallicity regions cannot be explained by pure gas accretion. Our spatially resolved analysis based on a more advanced gas regulator model results in a spatial map of net gaseous outflows, triggered by active central starbursts, that potentially play a significant role in shaping the spatial distribution of metallicity by effectively transporting stellar nucleosynthesis yields outwards. The relation between wind mass loading factors and stellar surface densities measured in different regions of our galaxies shows that a single type of wind mechanism, driven by either energy or momentum conservation, cannot explain the entire galaxy. These sources present a unique constraint on the effects of gas flows on the early phase of disk growth from the perspective of spatially resolved chemical evolution within individual systems.

Abstract
Plagioclase feldspars are among the most prevalent minerals in the solar system, and are present in many chondritic and achondritic meteorite families. Nevertheless, spectral features of plagioclases have never been unambiguously and directly observed in remote observations of asteroids. We report here the detection of an absorption band at 12.2 μm on Vesta spectra provided by ground-based spectral observations at the Subaru Telescope. This signature represents the first direct evidence of a widespread presence of crystalline Ca-rich plagioclase on Vesta and reveals that its regolith is comminuted to a very fine grain size, smaller than a few tens of microns, indicating that the mechanical brecciation process has been very effective. The crystalline nature of plagioclase strongly suggests that impacts alone cannot be the sole mechanism for regolith formation on Vesta and a milder process, such as thermal fatigue, should be invoked as an important and concomitant process Thermal fatigue should be considered a very effective process in regolith production and rejuvenation not only for near-Earth asteroids but even for large asteroids located in the main belt.
Radio Continuum Emission from Local Analogs of High-z Faint LAEs: Blueberry Galaxies
Authors: Sebastian Biny , Bait Omkar 
Published: September 2019

Abstract
We present a radio continuum study of a population of extremely young and starburst galaxies, termed as blueberries at ∼1 GHz using the upgraded Giant Metrewave Radio Telescope. We find that their radio-based star formation rate (SFR) is suppressed by a factor of ∼3.4 compared to the SFR based on optical emission lines. This might be due to (i) the young ages of these galaxies as a result of which a stable equilibrium via feedback from supernovae has not yet been established; (ii) escape of cosmic-ray electrons via diffusion or galactic-scale outflows. The estimated nonthermal fraction in these galaxies has a median value of ∼0.49, which is relatively lower than that in normal star-forming galaxies at such low frequencies. Their inferred equipartition magnetic field has a median value of 27 μG, which is higher than those in more evolved systems like spiral galaxies. Such high magnetic fields suggest that small-scale dynamo rather than large-scale dynamo mechanisms might be playing a major role in amplifying magnetic fields in these galaxies.
Prospective Study of Photorefractive Keratectomy for Myopia Using the VISX StarS2 Excimer Laser System
Authors: Stevens Julian , Giubilei Marco , Ficker Linda , Rosen Paul 
Published: September 2019

ABSTRACT
PURPOSE: To evaluate the safety, efficacy, and predictability of excimer laser photorefractive keratectomy (PRK) for compound myopic astigmatism using the VISX StarS2 excimer laser system with international version 3.1 software.
METHODS: We report a prospective consecutive study of myopic excimer laser PRK, performed in a multi-surgeon environment with 200 eyes of 117 patients, to correct naturally occurring compound myopic astigmatism of between -0.50 to -5.90 D manifest refractive sphere and up to -3.50 D manifest refractive astigmatism. Patients were assessed prior to surgery and at 1, 3, 6, and 12 months after treatment.
RESULTS: One hundred and ninety-eight of 200 treatments (99%) were reviewed 1 year after surgery; 193 of 198 eyes (97%) achieved 20/40 or better uncorrected visual acuity and 163 of 198 eyes (82%) achieved 20/20 or better. One eye lost two lines of Snellen visual acuity assessed at 12 months but recovered acuity when assessed at 18 months. Mean spherical equivalent corneal plane power was reduced from -3.50 to +0.90 D 1 month after treatment and 0 D at 12 months (SD 0.67 D). Three eyes of three patients underwent further treatment, two with LASDX and one with PRK for residual refractive error. Refractive astigmatism of >1.00 D was reduced from a mean -1.70 to -0.70 D at 1 year after treatment. Vector magnitude was 79% of that intended and mean vector axis error (absolute) was 8.5°. No eye had a severe haze response. Pelli-Robson contrast acuity was significantly reduced after treatment from a mean 1.72 D preoperatively to 1.63 D at 12 months (P<.01).
CONCLUSIONS: PRK for myopia using the VISX StarS2 excimer laser system was effective in the treatment of low myopic astigmatism, although there was a significant reduction in Pelli-Robson contrast sensitivity. [J Refract Surg 2002; 18: 502-5083
Sara Melody: Stripped Stark Naked in the Cycle
Authors: Brietzke Zander 
Published: September 2019

Abstract
Eugene O'Neill invoked the phrase “stripped stark naked” to describe the desired effect in The Iceman Cometh, but he actually used that same phrase, and several other similar iterations, in the immediately preceding Cycle plays, A Touch of the Poet and More Stately Mansions. Although the Cycle plays seem to set up what happens in O'Neill's “dive” play, they function differently. Sara Melody Harford, the protagonist, sinks almost as low as the derelicts at Hope's bar, but she does not stay sunk. Her husband, Simon, strips her naked, literally and figuratively, but she rejects the humiliation and transforms the violence into a purification rite. Sara sins against herself and her husband due to her passionate and greedy nature, but, unlike the characters in The Iceman Cometh, she redeems what she has done in the act of love. The Cycle dramatizes compulsive behavior, The Iceman Cometh showcases the art of denial.
Derechos humanos en la Universidad de La Frontera: Un diagnóstico sobre el conocimiento insuficiente de estudiantes de primer año
Authors: Castillo Leonardo , Morales Soledad 
Published: September 2019

Se presentan los resultados del proyecto «Derechos humanos en la Universidad de La Frontera: Un diagnóstico en los estudiantes de primer año», que investiga si los estudiantes que ingresan a primer año en la Universidad de La Frontera poseen conocimientos mínimos en materia de derechos humanos, en específico, aquéllos reconocidos en la Declaración Universal de Derechos Humanos de 1948, y cuál es su apreciación acerca de afirmaciones que relacionan tópicos de derechos humanos con el ejercicio de ciertos derechos políticos. Se parte de la hipótesis de que los estudiantes que egresan de la educación media no cuentan con una formación ciudadana suficiente, particularmente en materia de derechos humanos. Se abordan los cambios en el currículum de formación ciudadana, para posteriormente analizar conceptos de formación cívica, específicamente en derechos humanos. Se analiza la alta abstención electoral a la que
contribuye en parte la formación cívica insuficiente. Se presentan y analizan los resultados de la aplicación del instrumento de diagnóstico. Se trata de un estudio cuantitativo y descriptivo, de tipo transversal, cuya muestra fue seleccionada con 95 % de confianza. La recolección de datos se realizó mediante la creación de un instrumento, analizando los resultados mediante el software estadístico SPSS.
Aportes para la enseñanza universitaria de la historia reciente: Una revisita a las memorias de la dictadura argentina a través de dispositivos audiovisuales
Authors: Fernando Gómez Nicolás 
Published: September 2019

Enseñar lo acontecido en la última dictadura militar en Argentina representa constantes desafíos en las escuelas, pero enseñar a quienes pronto serán docentes involucra un orden distinto de responsabilidades. Atendiendo a estos problemas, en este artículo nos proponemos abordar una secuencia didáctica destinada a ser implementada en las universidades o instituciones de formación docente que tengan carreras afines al campo de la historia. Para ello, incorporamos el uso de recursos audiovisuales que resultan potentes en la complejización de la mirada sobre hechos de «carácter traumático» de la historia reciente en Argentina. En este marco, el artículo propone identificar las distintas memorias sobre la dictadura que circulan en las décadas de 1980, 1990 y 2000, en particular las que son hegemónicas en cada período. Estos elementos nos permiten evidenciar que las memorias nos «dicen» más sobre la coyuntura en las que son recuperadas,
y por ende construidas, que sobre aquello que se recuerda. Finalmente, este análisis dará cuenta también de las relaciones entre política estatal y memorias oficiales. Acompañar a nuestros estudiantes en la comprensión de estos procesos de rememoración de un pasado cercano traumático invita a deconstruir lo que damos por sentado y lo que naturalizamos cuando miramos el presente.

Published: September 2019

The application of dry cocoa bean shell ash (DCBSA) and NPK 15:15:15 for the improvement of soil fertility and yield of maize (Zea mays L.) was studied on an Alfisol South Western Nigeria, located at Joseph Ayo Babalola University Ikeji-Arakeji, Ilesa Osun State, Nigeria Teaching and Research Farm from April to July 2017 and from August to November 2016. Four treatments of dry cocoa bean shell ash (DCBSA) at 5 tonsha-1, NPK 15:15:15 at 300 kgha-1, dry cocoa bean shell ash (DCBSA) at 2.5 tonsha-1, mixed NPK 15:15:15 at 150 kgha-1 and control (C) were used in a Randomized Complete Block Design (RCBD) with three replications. The data collected were subjected to analysis of variance (ANOVA) and the means were compared by the use of Duncan multiple range test (DMRT) at 5% significance level. The study showed that dry cocoa bean shell ash (DCBSA) used alone can serve as a suitable alternative to inorganic fertilizer in the south western Nigeria, Especially, DCBSA has higher organic carbon than NPK dry cocoa bean shell ash (DCBSA) at 5 t ha-1, NPK 15:15:15 at 300 kg ha-1, dry cocoa bean shell ash (DCBSA) at 2.5 t ha-1, mixed NPK 15:15:15 at 150 kg ha-1 produced higher values for plant height, leaf area, chlorophyll, plant diameter, cob length, cob diameter and grain yield against the control that recorded the lowest value. Also. DCBSA improves soil pH as well as increases minerals such as Ca, Mg, Na and in particular, made available phosphorous due to its increment on soil pH. pH increased fro 5.3 to 7.8 DCBSA, N levels in the soil increased from 0.06g kg-1 to 2.61g kg-1 (DCBSA) and 2.10 g kg-1 (DCBTA + NPK). Organic carbon (OC) increased from 0.07 g kg-1 to 2.87g kg-1 DCBSA plot. P level decreased from 3.7 mg dm-3 to 1.09 mg dm-3 (DCBSA) and 1.81 mg dm-3 (NPK) and 1.42 mg dm-3 (DCBSA + NPK) which was an indication of P availability to crop during growing season. Maize grain yield increased from 0.77 tonsha-1 in the control plot to 1.25 t ha-1 in DCBSA plot, 1.22 t ha-1 a in NPK plot and 1.26 t ha-1. in DCBSA + NPK plot. The study recommends an application rate of 5 t ha-1 of dry cocoa shell ash (DCBSA) alone or 2.5 t ha-1 combination each of (DCBSA + NPK) for maize yield and fertility improvement on this type of soil in this agro - ecology.
