Prototype of Gas Leak Detector System Using Microcontroller and SMS Gateway
Authors: Tombeng Marchel Thimoty 
Published: April 2018

On of the very important things in human life is home safety. Home Safety refers to the awareness of risks and potential dangers in and around home which may cause bodily harm, or even death. Awareness and vigilance is indispensable in preventing the threatening risks and potential dangers. Therefore, people needs a timely warning information about gas leak for prevention of home safety threatening risks and potential dangers. This warning information will allow people, users, or residents to reduce the risks and potential dangers caused by gas leak, especially when they are away from home. This paper describes the development of system technology regarding the gas leak detector which integrates the MQ2 gas sensor, Arduino Uno R3 Microcontroller and the Sim900 SMS Gateway. Keywords : MQ2 Sensor, Arduino Uno R3, Sim900, LPG
Politics of (Im)moderation: The Production of South Asian Identities in the Canadian Apology for Air India Flight 182
Authors: Busse Cassel 
Published: April 2018

Moderation, we are frequently told, is the key to a successful and fulfilling life: “everything in moderation,” and you will succeed, find happiness and become a well-adjusted member of society. The self-regulative function of “moderation”— whether in terms of one’s social life, nutritional habits or, in the case of this paper’s focus, political views and actions—has become a standard of capitalist Western citizenship and bourgeois political etiquette since Aristotle’s Nicomachean Ethics. As political theorist Wendy Brown notes in Regulating Aversion (2006), the polarization of the politically secular and liberal versus fundamentalist and radical has emerged as “part of a civilization discourse that identifies both tolerance and the tolerable with the West” (6). Bringing this analysis of social and political moderation to a Canadian context, I examine the use of the “moderate” in Stephen Harper’s 2010 apology for the Canadian government’s belated recognition of the bombing of Air India Flight 182 as a Canadian tragedy. This paper argues that in its supposed imperative of reconciliation, the Harper government does not question the racism against Indo- Canadians that has contributed to the dismissal of the bombing; instead, the government produces a binary between the radical, anachronistic terrorist and the “model minority” South Asian immigrant. The Harper apology not only makes any resistance to Canada’s “multicultural tolerance” irrational, but it also displaces all violent motives onto the foreign, South Asian body. The goal of this paper is to argue against the overt and systemic racism within Harper’s 2010 apology for Flight 182, and question the use of moderation in the political discourse of Canadian “diversity,” a discourse as innocuous and inclusive as it is deceitful, oppressive and even fatal.
To Sell “Reconciliation”: 8th Fire, Idle No More and the Possibilities of Reconciliation
Authors: McLeod Steven 
Published: April 2018

The Canadian Broadcasting Corporation documentary series 8th Fire seems designed to reassure its imagined non-Indigenous audience that reconciliation with Indigenous peoples can emerge without challenges to hegemonic beliefs in the primacy of the individual pursuit of wealth and the commodification of land. Although the series gives some scope to positions that contest the hegemony of these driving principles of neoliberalism—positions held by Indigenous nations and their allies seeking decolonization—8th Fire contains the energy of such challenges within its own representation of the most viable terms for reconciliation. By marketing reconciliation to its audience as a pathway to a neoliberal sense of prosperity, 8th Fire risks constraining the possibilities of reconciliation to the most instrumentalized form.. The mobilization of Indigenous and non-Indigenous communities during recent months under the banner of Idle No More has demonstrated the potential for a form of reconciliation that is very different from that suggested by 8th Fire. Idle No More demands that Indigenous peoples’ right to a unique form of citizenship be respected and that resource development be sustainable. In offering its terms for reconciliation, 8th Fire similarly invites non-Indigenous viewers to witness and participate in representations of Indigenous cultural identity. In Canada, powwows occasion such gatherings of Indigenous and non-Indigenous people on Indigenous terms. In this article, I discuss the broadcast content of 8th Fire and also examine its digital platform alongside the Idle No More movement. While I argue that the content of the 8th Fire documentary risks constraining the possibilities of reconciliation within parameters set by neoliberal imaginings of prosperity, I will show how the 8th Fire website and Idle No More demonstrate the potential for an alternative form of reconciliation, one grounded in the inclusive celebration of Indigenous cultural continuity and the ceremony of kinship between Indigenous peoples and land occasioned by powwow.
« Que cette demeure de Śrīpati dure sur terre... ». L'inscription préangkorienne K. 1254 du musée d'Angkor Borei
Authors: Goodall Dominic , Gerschheimer Gerdi 
Published: April 2018

Cet article présente une stèle inscrite préangkorienne inédite dont l'écriture est d'une facture calligraphique exceptionnelle. Le texte ne contient pas de date, mais l'inscription relate l'installation d'une image de Viṣṇu par un certain Jayavarman, probablement le roi Jayavarman I bis du VIIIe siècle. À en juger par l'endroit où la stèle a été trouvée en 1993, le temple qui abritait cette image s'élevait sur la rive nord de la rivière qui coule à quelques dizaines de mètres du nouveau musée d'Angkor Borei. Les onze premières des vingt stances consistent en un hymne à la gloire de diverses manifestations (prādurbhāva ) de Viṣṇu ; cinq stances font ensuite l'éloge du roi, présenté comme une incarnation partielle de Viṣṇu ; puis deux strophes rapportent la fonte, apparemment en argent, et l'installation de l'image de Viṣṇu, Tribhuvanañjaya ; les deux dernières strophes mentionnent la création du temple – probablement en matériaux moins durables que la stèle, puisqu'aucune trace n'en subsiste – par un courtisan du roi (rājavallabha).
Through-Focus Optical Bench Performance of Extended Depth-of-Focus and Bifocal Intraocular Lenses Compared to a Monofocal Lens
Authors: Yoo Young-Sik , Whang Woong-Joo , Byun Yong-Soo , Piao Jun Jie , Kim Dae Yu , Joo Choun-Ki , Yoon Geunyoung 
Published: April 2018

PURPOSE:
To analyze the optical performance and the effect of halos on modulation transfer function (MTF) of an extended depth-of-focus (EDOF) intraocular lens (IOL) compared to low add bifocal, high add bifocal, and monofocal IOLs.

METHODS:
The optical bench system was set up to evaluate the MTF and point spread function images for analyzing halos around the focused image with four different IOLs (TECNIS ZCB00, ZXR00, ZKB00, and ZMB00; Abbott Medical Optics, Inc., Santa Ana, CA). They were measured within a defocus range from +0.50 to −4.00 diopters (D).

RESULTS:

The EDOF IOL showed good and stable image quality from far to intermediate distance. The near visual performance was limited with the EDOF IOL compared to low add and high add power bifocal IOLs. Monofocal and EDOF IOLs focused light more tightly at far distance and showed higher intensity at the core compared to low and high add bifocal IOLs. The peak core intensity and the relative halo intensity of the EDOF IOL were comparable to those obtained from the monofocal IOL. A negative significant correlation was found in all IOLs between the relative halo intensity and MTF within a defocus diopter range from 0.00 to −3.00 D (
P
< .05).

CONCLUSIONS:
The EDOF IOL had distance acuity optical quality and halo effect similar to monofocal IOLs but worse near acuity compared to conventional bifocal IOLs.

Comparison of the Visual Performance After Implantation of Bifocal and Trifocal Intraocular Lenses Having an Identical Platform
Authors: Liu Xiaomin , Xie Lixin , Huang Yusen 
Published: April 2018

PURPOSE:
To compare the visual performance after bilateral implantation of a diffractive bifocal or trifocal intraocular lens (IOL) from the same manufacturer using the same IOL platform.

METHODS:
This prospective, non-randomized, controlled study involved patients who had cataract surgery with bilateral implantation of bifocal or trifocal IOLs. The near, intermediate, and distance visual acuities, defocus curve, optical quality including modulation transfer functions and higher-order aberrations, National Eye Institute Visual Functioning Questionnaire-14, patient satisfaction, spectacle independence, and perception of visual disturbances were assessed in all patients.

RESULTS:

Fifty eyes (25 patients) were implanted with a diffractive trifocal IOL (AT LISA tri 839MP; Carl Zeiss Meditec, Jena, Germany) and 60 eyes (30 patients) with a diffractive bifocal IOL (AT LISA 809M; Carl Zeiss Meditec). The follow-up was 3 months. No statistically significant difference was found in distance or near visual acuity between the two groups (
P
≥ .05). Uncorrected, corrected, and distance-corrected intermediate visual acuities were significantly better in the trifocal IOL group (
P
< .01). In the binocular defocus curve, the visual acuity was also significantly better for defocus of −1.00 to −2.00 diopters in eyes with trifocal IOL implantation (
P
< .01). Similar halos and glare were present in the two groups. The levels of overall satisfaction were similarly high between groups.

CONCLUSIONS:
Diffractive trifocal IOLs can provide significantly better intermediate vision and equivalent distance and near visual performance compared to bifocal IOLs and do not induce extra qualitative vision disturbances.

Juan Rulfo: Fotografía, literatura y música. Experiencias y propuestas pedagógicas
Authors: Prieto Aguaza Alberto 
Published: April 2018

En la primera parte de la comunicación pretendo sintetizar los aspectos básicos de la relación entre la obra literaria de Juan Rulfo (Pedro Páramo y El llano en llamas) y su cada vez más reconocida obra fotográfica. Si bien han sido marcadas ambas prácticas artísticas como independientes, no es menos cierto que comparten un idéntico origen poético y perceptivo sobre la vida y la muerte en general, y sobre el ser mexicano en particular, atendiendo en este sentido a la configuración social del país desde la colonización. El sincretismo religioso mexicano -sustrato indígena y catolicismo posterior-, así como la violencia de la colonización y los procesos revolucionarios posteriores influyen en la visión de Rulfo, pues la muerte, el olvido, la culpa y el rencor son aspectos que resuenan en el silencio y las sombras de sus tomas fotográficas y en las palabras de los fantasmas de Comala. Aprovechando el centenario del nacimiento de Juan Rulfo, he intentado acercar a estudiantes diversos la estética de Rulfo desde unos presupuestos interdisciplinares, explorando la conexión emocional de las imágenes como en un viaje de ida y vuelta, en el que las fotografías y las palabras se retroalimentan. En un primer momento decidí aprovechar dos contextos educativos de diferente ámbito en los que imparto clases desde hace años: la Escuela Internacional de Fotografía GrisArt y el Institut de música y bachillerato Oriol Martorell. Así, los alumnos del primer centro parten de las imágenes para llegar a los textos, y, viceversa, los del segundo leen la novela para acabar visualizando las fotografías. Como engarce complementario decidí incorporar la música a las propuestas pedagógicas, pues el silencio como elemento estético es capital en las tres disiciplinas, ayudando a envolver las fotografías y las palabras de Rulfo de otras lecturas y visualizaciones. Esto es lo que nos ofrece Ghosts of Comala, versión musicada de la novela de Rulfo, que ha compuesto Àlex Torío. A pesar de las diferentes propuestas, el acercamiento interdisciplinar a la obra de Rulfo se ofrece como un juego de asociaciones en el que se pueden compaginar, en diversas dosis y emparejamientos, fragmentos literarios, fotografías y música (con y sin texto). En una sesión en GrisArt, además de escuchar en directo temas del disco, participaron Ramon Reverte, editor creativo de RM, para tratar sobre el estudio y edición del archivo fotográfico de Rulfo, y la fotógrafa Anna Galí, autora de las imágenes del disco, remedo libre que compagina la atmosfera mortuoria del disco de Àlex Torío con las imágenes de la novela y las fotos de Rulfo. En último lugar, cabría destacar que las prácticas llevadas a cabo se presentan como un primer paso para avanzar en propuestas en las que los alumnos pasen de entender globalmente el mundo de Rulfo, a crear ellos, empleando alguno de los otros medios de expresión: así, realizar fotos en GrisArt a partir de los textos, o escribir textos y componer música a partir de las fotos, en el Instituto Oriol Martorell.
La dynamis de la imagen fotográfica
Authors: Garcia Orallo Robert 
Published: April 2018

El giro hacia la imagen producido en las últimas décadas ha situado la fotografía en el centro de unos análisis sobre unas imágenes que se mueven entre la sospecha y la fascinación por su potencia. A pesar de ello los modos de hacer de las sociedades contemporáneas a través de nuevos imaginarios ayudan a generalizar la opinión que la imagen se encuentra inmersa en una profunda crisis de credibilidad y de comunicabilidad como resultado del secuestro de aquella autonomía que tanto preocupó a la Escuela de Frankfurt. Ante esto, nuestra intención es presentar, desde una posición crítica pero también desde la fascinación por la potencia de la imagen, una propuesta metodológica dirigida a mostrar de qué manera la imagen que acompaña el medio fotográfico configura el lugar idóneo para debatir sobre las maneras de crear sentido en la actualidad. Para Giorgio Agamben, un crítico también de la autonomía, no es posible progresar en una definición de la imagen si no se comprende antes el hecho que esta aparece en la contemporaneidad como algo imposible. En la imagen se muestra aquello que es repetible y reproducible, pero, al mismo tiempo, se expone la aparición de algo único. Por lo tanto, desde una perspectiva ontológica las imágenes en cuanto tales no significan nada más que el lugar para una dualidad irreductible. Sólo es en el momento en que intentamos apropiarnos de ellas, de su exposición, que las imágenes aparecen como dispositivo en la forma imagen-exposición, abriéndose tanto a la comunicabilidad como a la posibilidad de su captura y manipulación. Este es precisamente el lugar que ofrece el medio fotográfico. Adoptamos aquí el análisis que realiza Agamben sobre el atlas Mnemosyne de Aby Warburg para crear una analogía capaz de situar la imagen fotográfica como el lugar privilegiado para constatar la potencialidad de un análisis centrado en la imagen-exposición. Aquello que, respondiendo a esta dualidad del dispositivo, es capturado y a la vez expuesto en las imágenes del Atlas Warbugniano, es identificado por Agamben como "gesto". Por un lado una fotografía, como cada imagen en Warburg, es la reificación y cierre del gesto (imagen-símbolo) mientras que por otro es la preservación y exposición de su dynamis (imagen-dynamis). La dynamis capturada en nuestras imágenes fotográficas acaba refiriendo a otras imágenes como fragmentos del mismo gesto a modo de fotogramas de una película que ya no puede ser vista. Poder identificar la dynamis del gesto, más allá de lo fijado en la imagen, permite su propia reversibilidad abriendo la fotografía hacia la experiencia de la comunicabilidad frente a un simple mensaje intercambiable. A partir de la estructura imagen-exposición, Agamben acaba construyendo un paradigma de la imagen que, funcionando por analogía, se convierte -como reconoce Didi-Huberman- en una autentica epistemología del ejemplo. Esto permite situarnos en el campo de lucha que abre la imagen armados con un esquema teórico definido y un instrumento útil para analizar y plantear estrategias válidas para la praxis fotográfica contemporánea.
Shifting borderlands
Authors: Camminga B 
Published: April 2018

Abstract
Within Africa’s long history of migration, this article focuses on the specific context of South Africa’s recent influx of people fleeing persecution, violence, and discrimination on the grounds of their gender identity/expression. This paper conceptualises people who can make claims to the refugee status, fleeing their countries of origin based on the persecution of their gender identity as ‘gender refugees’. I argue that gender refugees are different from sexual refugees in that their pre-dominant forced migration issue pertains to their gender identity, which is perceived as incongruent to their birth-assigned sex. Drawing on life story interviews carried out by the author between 2013 and 2015 with gender refugees living in South Africa, along with analysis of media and archival materials, this paper explores how, when, and under what circumstances transgender-identified individuals from countries in Africa are forced to journey, and come to seek refuge in South Africa specifically. Utilising the notions of ‘shifting’ and ‘discomfort’ as analytics in relation to narratives provided, I suggest that South Africa functions as a pan-African national imaginary, even for migrants, which represents a particular understanding of freedom due to widespread knowledge of its unique Constitutional precepts. In conclusion, I emphasise how the State in gender refugees’ countries of origin, which sanctions the possibility of death for transgender people as exemplary subjects, plays an especially transformative role in the decision to flee.
Using barometric time series of the IMS infrasound network for a global analysis of thermally induced atmospheric tides
Authors: Hupe Patrick , Ceranna Lars , Pilger Christoph 
Published: April 2018

Abstract. The International Monitoring System (IMS) has been established to monitor compliance with the Comprehensive Nuclear-Test-Ban Treaty and comprises four technologies, one of which is infrasound. When fully established, the IMS infrasound network consists of 60 sites uniformly distributed around the globe. Besides its primary purpose of determining explosions in the atmosphere, the recorded data reveal information on other anthropogenic and natural infrasound sources. Furthermore, the almost continuous multi-year recordings of differential and absolute air pressure allow for analysing the atmospheric conditions. In this paper, spectral analysis tools are applied to derive atmospheric dynamics from barometric time series. Based on the solar atmospheric tides, a methodology for performing geographic and temporal variability analyses is presented, which is supposed to serve for upcoming studies related to atmospheric dynamics. The surplus value of using the IMS infrasound network data for such purposes is demonstrated by comparing the findings on the thermal tides with previous studies and the Modern-Era Retrospective analysis for Research and Applications Version 2 (MERRA-2), which represents the solar tides well in its surface pressure fields. Absolute air pressure recordings reveal geographical characteristics of atmospheric tides related to the solar day and even to the lunar day. We therefore claim the chosen methodology of using the IMS infrasound network to be applicable for global and temporal studies on specific atmospheric dynamics. Given the accuracy and high temporal resolution of the barometric data from the IMS infrasound network, interactions with gravity waves and planetary waves can be examined in future for refining the knowledge of atmospheric dynamics, e.g. the origin of tidal harmonics up to 9 cycles per day as found in the barometric data sets. Data assimilation in empirical models of solar tides would be a valuable application of the IMS infrasound data.

Abstract. Reanalysis data show an increasing trend in Arctic precipitation over the 20th century, but changes are not homogenous across seasons or space. The observed hydroclimate changes are expected to continue and possibly accelerate in the coming century, not only affecting pan-Arctic natural ecosystems and human activities, but also lower latitudes through the atmospheric and ocean circulations. However, a lack of spatiotemporal observational data makes reliable quantification of Arctic hydroclimate change difficult, especially in a long-term context. To understand Arctic hydroclimate and its variability prior to the instrumental record, climate proxy records are needed. The purpose of this review is to summarise the current understanding of Arctic hydroclimate during the past 2000 years. First, the paper reviews the main natural archives and proxies used to infer past hydroclimate variations in this remote region and outlines the difficulty of disentangling the moisture from the temperature signal in these records. Second, a comparison of two sets of hydroclimate records covering the Common Era from two data-rich regions, North America and Fennoscandia, reveals inter- and intra-regional differences. Third, building on earlier work, this paper shows the potential for providing a high-resolution hydroclimate reconstruction for the Arctic and a comparison with last-millennium simulations from fully coupled climate models. In general, hydroclimate proxies and simulations indicate that the Medieval Climate Anomaly tends to have been wetter than the Little Ice Age (LIA), but there are large regional differences. However, the regional coverage of the proxy data is inadequate, with distinct data gaps in most of Eurasia and parts of North America, making robust assessments for the whole Arctic impossible at present. To fully assess pan-Arctic hydroclimate variability for the last 2 millennia, additional proxy records are required.
Posibilidades educativas en los módulos de respeto. Análisis de un caso
Authors: Galán Casado Diego , Gil Cantero Fernando 
Published: April 2018

El objetivo concreto es presentar los resultados de una investigación acerca de las posibilidades educativas del Módulo 5 de Respeto de la prisión de Valdemoro de la Comunidad de Madrid a través de la información aportada por los propios presos y los funcionarios que trabajan en estos módulos. La investigación con respecto a los internos ha recurrido al método biográfico-narrativo, estudio de caso múltiple, centrándonos en las historias de vida cruzadas, de tipo interpretativo, buscando la elaboración de categorías sociales y personales de carácter educativo, centradas en las experiencias de vida en el módulo de respeto. En relación a los funcionarios hemos recurrido a unas entrevistas semiestructuradas. La investigación muestra unas diferencias claras del Módulo 5 de Respeto con respecto a los módulos ordinarios. Estas diferencias se centran en destacar tanto por parte de los internos como de los funcionarios los siguientes aspectos: un estilo de vida más parecido al de afuera de la prisión (centrado en horarios rigurosos, normas claras y exigentes de actuación, refuerzos positivos y negativos continuos, participación y organización de actividades) y una percepción biográfica de cambio personal (referido en los relatos a una ruptura con estilos de vida pasada, una valoración presente que gira en torno a la formación y preparación, unas expectativas positivas futuras de mantenerse alejado de la carrera delictiva y, por último, una perspectiva personal de la reinserción referida a un nuevo comienzo de vida).
