Cyberactivisim in the process of political and social change in Arab Countries
Authors: Soengas-Pérez Xosé , Assif Mohamed 
Published: July 2017

This research analyses the contribution of cyberactivism to the political and social change in Tunisia, Egypt and Libya, as well as the opinion of young Arabs on the present context. Meaningful information has been extracted from regular interviews to 30 undergraduates over a five-year period. These students had already participated in the process boosting the Arab Spring in 2011, and they keep practising cyberactivism ever since. The use of a mixed method research allows for carrying out a study where quantitative elements are complemented by qualitative ones. Findings show that Arab countries have not yet shaken off the former structures that supported the regimes preceding 2011, which are those that hamper the consolidation of a modern country. At the moment, there are still two conflicting realities between millenary traditions and values connected to revolutions and symbols of progressivism in Tunisia, Egypt and Libya. In a context where the unity of action action is needed, cyberactivism plays an essential role, as it brings together critical citizens in a common and virtual space. These groups are committed to change, they keep in touch with the outside world and beyond censorship, they make protests visible to the international arena, and monitor government actions.
Esta investigación analiza la contribución del ciberactivismo al cambio político y social en Túnez, en Egipto y en Libia, y la opinión de los jóvenes árabes sobre la situación actual. Para disponer de información relevante sobre estos hechos se ha entrevistado periódicamente durante los últimos cinco años a 30 universitarios que ya habían participado en el proceso que impulsó las revueltas de 2011 y que siguen siendo ciberactivistas desde entonces. La utilización de una metodología mixta permite realizar un estudio donde los aspectos de carácter cuantitativo se complementan con contenidos cualitativos. Los resultados demuestran que los países árabes todavía no se han desprendido de muchas de las estructuras que sostenían a los regímenes anteriores a 2011, que son las que dificultan la consolidación de un sistema moderno. En este momento en Túnez, en Egipto y en Libia todavía conviven dos realidades que provocan un choque permanente entre las tradiciones milenarias, muy arraigadas en determinados sectores de la sociedad, y los valores asociados a las revoluciones, más progresistas. En un contexto donde es necesaria la unidad de acción, el ciberactivismo juega un papel fundamental porque congrega en un espacio virtual común a la ciudadanía crítica comprometida con el proceso de cambio, permite organizarse, mantener contacto con el exterior al margen de la censura oficial, hacer visibles las protestas en escenarios internacionales y vigilar las acciones del Gobierno.
Nouvelles perspectives dans la littérature brésilienne contemporaine : Vozes-Mulheres et Quantos filhos Natalina teve ? de Conceição Evaristo
Authors: Champagnat Pauline 
Published: July 2017

Cet article se propose d’analyser une des manifestations du féminisme brésilien contemporain dans les oeuvres Vozes-Mulheres (1990) et Quantos filhos Natalina teve ? (2015) de Conceição Evaristo sous le prisme des études de genre et des études post-coloniales. Dans un premier temps, nous questionnerons une nouvelle branche du féminisme brésilien : l’intersectionnalité. Après une brève définition du concept, nous expliquerons de quelle manière il s’insère dans le contexte du féminisme brésilien actuel. Dans un deuxième temps, nous nous pencherons sur l’analyse du conte Quantos filhos Natalina teve ? de Conceição Evaristo, ce qui nous permettra d’évoquer le concept de non-famille suggéré par Edouard Glissant, ce conte étant une illustration possible de ce concept. Nous évoquerons le concept de matrifocalité comme marque de l’esclavage mais également comme structure familiale héritée de l’Afrique. Puis finalement, nous analyserons le poème Vozes-Mulheres, également de Conceição Evaristo, qui rompt avec le concept de fragmentation familiale évoqué précédemment.

Published: July 2017

Abstract
Curing kinetics of an industrially important printed-circuit board (PCB) base material (epoxy–phenol/glass fillers) were studied by isothermal differential scanning calorimetry (DSC) measurements between 150 and 190°C, as relevant curing temperatures for the PCB industry. The extent of cure was calculated by integration of the exothermic peak and normalization by the total heat of reaction (obtained by nonisothermal DSC). Although the cross-linking was completed above 180°C, the kinetic profiles show two regimes: one fast and one slow. The kinetic parameters have been elucidated using an isoconversional model-free kinetic method, with the exact method of Friedman, to give to the PCB manufacturers a road map to predict curing behavior of base material. The linearity of Arrhenius plots was satisfactory. The apparent activation energy of curing reaction has been found to increase with the degree of conversion. The elucidation of the kinetic parameters allows us to propose an accurate and predictive description of the curing kinetics within the fast regimen of reaction (i.e., without vitrification). Finally, we discuss how these kinetic measurements and models can be completed and optimized.

Published: July 2017

ABSTRACT

Purpose
To determine the outcome and safety of endoscopic dacryocystorhinostomy (ENDO-DCR) with the use of silicon stents in nasolacrimal duct obstruction (NLDO).

Materials and methods
This study was done in the Department of Otorhinolaryngology and Head and Neck Surgery, Navodaya Medical College, Raichur, from January 2013 to June 2015, with a total of 82 cases (10 cases with bilateral disease) who underwent a standardized procedure, with an endonasal approach to the lacrimal sac, surgical removal of nasal mucosa, lacrimal bone, and a fragment of the frontal process of the maxilla. The medial wall of the lacrimal sac was removed completely and canalicular silicone intubation tube was placed for 6 weeks postoperatively.
Main outcome measures were resolution of epiphora, absence of discharge, and patency of the ostium confirmed by irrigation and endoscopic evaluation of neo-ostium at 6 weeks.

Results
The ENDO-DCR procedure with adjunctive canalicular silicone intubation tube was successful in 78 (95%) cases. No significant complications were encountered during or after the operative period.

Conclusion
Endoscopic dacryocystorhinostomy with canalicular silicon intubation for shorter duration (6 weeks) is a safe and successful procedure for the treatment of NLDO in adults as well as in children, with a success rate of 95%.

Authors: Rao SV Manjunatha 
Published: July 2017

ABSTRACTAimTo evaluate the efficacy and results of radiofrequency turbinoplasty in patients with rhinitis medicamentosa due to imidazolines like oxymetazoline and xylometazoline.Study designThis is a prospective, single-blinded, randomized controlled study.Materials and methodsStudy was conducted on 20 patients in a tertiary level center from January 2010 to February 2016. Patients with symptoms and signs of nasal obstruction due to rhinitis medicamentosa were selected. Patients were aged from 16 to 43 years (mean age is 24 years). Twelve were males and eight were females. The duration of use of nasal decongestant drops varied from 3 months to 5 years. The turbinoplasty was performed using the radiofrequency method. Nasal obstruction symptom evaluation (NOSE) questionnaires are used for subjective assessment and nasal endoscopy view score (NES) was used for objective assessment pre- and postoperatively. Follow-up was done at the end of 15 days and 3 months after surgery. The results were statistically analyzed by paired t-test.ResultsThe mean NOSE score before procedure was 92. At the 15th postoperative day, mean NOSE score reduced to 1.3 and it further reduced at the 3rd month to 0.5 (p < 0.001), with 99.5% reduction in subjective symptoms. The mean NES before procedure was 3.95. On the 15th day, it was 0.35 and at the end of 3rd month, it was 0 with 91.1% reduction in objective evaluation (p < 0.001). Results were same on left and right side of nose. No major postoperative complication was observed in patients.ConclusionRadiofrequency turbinoplasty technique can be recommended as an effective method in imidazoline-induced rhinitis medicamentosa. It is simple, comfortable, fast relief giving, no repeated steroids, and cost-effective, single-session treatment. Good compliance and cooperation from patients can be obtained with no major complications of the treatment. It allows patients to be managed in the office environment.How to cite this articleRao SVM.

ABSTRACT

Objective
The aim of the study is to evaluate the age, sex, site of lesion, histopathological diagnosis, and recurrence rate of the maxillectomy patients.

Materials and methods
A retrospective study was done in 42 patients, who underwent maxillectomy for malignant growth of the nose and paranasal sinuses from 2006 to 2015 at our center.

Results
The most common age group is 55 to 65 years (73.8), with male predominance (66.7%). Among symptoms prevalent is nasal obstruction (47%). Maxillary sinus is the most common site of origin (61.9%). Squamous cell carcinoma is the most common histopathological diagnosis (52.4%) and recurrence rate is 16%.

Conclusion
Exact clearance, reconstruction, postoperative care, and perfect teamwork play a vital role. Thus, successful outcome of maxillectomy is multifactorial.

Adenoidectomy: Conventional or Endoscopic Assisted?
Authors: Goel Anuj K 
Published: July 2017

ABSTRACTObjectivesAdenoid hypertrophy is known as the most common cause of nasal obstruction in children; thus, adenoidectomy is one of the most commonly performed surgical procedures in the pediatric population. We performed both conventional and endoscopic-assisted adenoidectomies in 54 patients. Our objectives were to compare the efficacy of both methods in terms of subjective and objective relief of symptoms, safety, recurrence, and postoperative morbidity.Materials and methodsFifty-four patients were studied and were diagnosed depending upon clinical examination and radiological investigation. The patients were operated by either conventional or endoscopic-assisted adenoidectomy (EAA). Intraoperative and postoperative complications were looked for. After discharge from the hospital, the patients were called for follow-up on 1st week, 3rd week, 2nd and 4th month, and patients were asked for relief of symptoms and examined for nasal disease and for recurrence.ResultsAdenoid hypertrophy was seen commonly in children and the most common presenting complaints were nasal obstruction, mouth breathing, and snoring. The patients were diagnosed to have chronic adenoiditis, chronic adenotonsillitis, with or without chronic suppurative otitis media. More number of patients became symptom free with EAA as compared with conventional adenoidectomy.ConclusionConventional adenoidectomy and EAA both have comparable success rates. Endoscopic-assisted adenoidectomy allows complete removal of adenoid tissue, thereby reducing the chances of developing recurrent adenoid obstructive symptoms and reducing the bacterial reservoir in the nasopharynx.How to cite this articleGoel AK.

Malignancy mimicking Juvenile Nasopharyngeal Angiofibroma
Authors: Kaur Navjot , Tiwana Harsimran , Sawhney Shikhar 
Published: July 2017

ABSTRACT
Nasopharyngeal masses in young males can be benign or malignant. As the treatment regimen for these masses differs considerably, it is crucial to differentiate benign from malignant masses for successful and adequate treatment of patients and also for minimizing morbidity from unnecessary interventions. We are presenting two case reports of patients with nasopharyngeal carcinoma (NPC) mimicking juvenile nasopharyngeal angiofibroma (JNA). Both the cases were presumed as JNA and underwent excessive surgical intervention only to reveal NPC on final histopathology report. We wish to highlight the importance of complete clinical examination and preoperative imaging in differentiating an ideal management of nasopharyngeal masses.

Authors: Dhawan Pankaj , Tandan Piyush , Grover Amrita , Madhukar Pankajz 
Published: July 2017

ABSTRACT

Aim
To evaluate the existence of different esthetic smile criteria in a section of North Indian population.

Materials and methods
A total of 100 students from Manav Rachna International University were selected based on the inclusion criteria. Two photographs were taken (smiling face and smile) using Digital Single Lens Reflex camera. The statistical analyses used were descriptive statistical tests and Spearman correlation after the images were analyzed using Digimizer image analysis software for different esthetic smile criteria.

Results
The coincidence of the facial midline with the arch midline occurred in more than half of the students. Most of the subjects presented parallelism between the incisal plane and the interpupillary line. Mostly parallel or straight smiles were also most commonly observed and the gingival display and the amount of gingival display were relatively less observed.

Conclusion
There exists a relationship between facial midline, interpupillary line, smile arc, gingival display, and facial esthetics.

Clinical significance
This article describes the existence of different esthetic smile criteria in enhancing the facial esthetics for a pleasing smile.

Improved pointing information for SCIAMACHY from in-flight measurements of the viewing directions towards sun and moon
Authors: Bramstedt Klaus , Stone Thomas C. , Gottwald Manfred , Noël Stefan , Bovensmann Heinrich , Burrows John P. 
Published: July 2017

Abstract. The SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY) on Envisat (2002–2012) performed nadir, limb, solar/lunar occultation and various monitoring measurements. The pointing information of the instrument is determined by the attitude information of the Envisat platform with its star trackers together with the encoder readouts of both the azimuth and the elevation scanner of SCIAMACHY. In this work, we present additional sources of attitude information from the SCIAMACHY measurements itself. The basic principle is the same as used by the star tracker: we measure the viewing direction towards celestial objects, i.e. sun and moon, to detect possible mispointings. In sun over limb port observations, we utilise the vertical scans over the solar disk. In horizontal direction, SCIAMACHY's sun follower device (SFD) is used to adjust the viewing direction. Moon over limb port measurements use for both the vertical and the horizontal direction the adjustment by the SFD. The viewing direction is steered towards the intensity centroid of the illuminated part of the lunar disk. We use reference images from the USGS Robotic Lunar Observatory (ROLO) to take into account the inhomogeneous surface and the variations by lunar libration and phase to parameterise the location of the intensity centroid from the observation geometry. Solar observations through SCIAMACHY's so-called sub-solar port (with a viewing direction closely to zenith) also use the SFD in the vertical direction. In the horizontal direction the geometry of the port defines the viewing direction. Using these three type of measurements, we fit improved mispointing parameters by minimising the pointing offsets in elevation and azimuth. The geolocation of all retrieved products will benefit from this; the tangent heights are especially improved. The altitudes assigned to SCIAMACHY's solar occultation measurements are changed in the range of −130 to −330 m, the lunar occultation measurements are changed in the range of 0 to +130 m and the limb measurements are changed in the range of −50 to +60 m (depending on season, altitude and azimuth angle). The horizontal location of the tangent point is changed by about 5 km for all measurements. These updates are implemented in version 9 of the SCIAMACHY Level 1b products and Level 2 version 7 (based on L1b version 9).
Revisiting the Ceara Rise, equatorial Atlantic Ocean: isotope stratigraphy of ODP Leg 154 from 0 to 5 Ma
Authors: Wilkens Roy H. , Westerhold Thomas , Drury Anna J. , Lyle Mitchell , Gorgas Thomas , Tian Jun 
Published: July 2017

Abstract. Isotope stratigraphy has become the method of choice for investigating both past ocean temperatures and global ice volume. Lisiecki and Raymo (2005) published a stacked record of 57 globally distributed benthic δ18O records versus age (LR04 stack). In this study LR04 is compared to high-resolution records collected at all of the sites drilled during ODP Leg 154 on the Ceara Rise, in the western equatorial Atlantic Ocean. Newly developed software is used to check data splices of the Ceara Rise sites and better align out-of-splice data with in-splice data. Core images recovered from core table photos are depth and age scaled and greatly assist in the data analysis. The entire splices of ODP sites 925, 926, 927, 928 and 929 were reviewed. Most changes were minor although several were large enough to affect age models based on orbital tuning. A Ceara Rise composite record of benthic δ18O is out of sync with LR04 between 1.80 and 1.90 Ma, where LR04 exhibits two maxima but Ceara Rise data contain only one. The interval between 4.0 and 4.5 Ma in the Ceara Rise compilation is decidedly different from LR04, reflecting both the low amplitude of the signal over this interval and the limited amount of data available for the LR04 stack. A regional difference in benthic δ18O of 0.2 ‰ relative to LR04 was found. Independent tuning of Site 926 images and physical property data to the Laskar et al. (2004) orbital solution and integration of available benthic stable isotope data from the Ceara Rise provides a new regional reference section for the equatorial Atlantic covering the last 5 million years.
Quantifying the added value of convection-permitting climate simulations in complex terrain: a systematic evaluation of WRF over the Himalayas

Published: July 2017

Abstract. Mesoscale dynamical refinements of global climate models or atmospheric reanalysis have shown their potential to resolve intricate atmospheric processes, their land surface interactions, and subsequently, realistic distribution of climatic fields in complex terrains. Given that such potential is yet to be explored within the central Himalayan region of Nepal, we investigate the skill of the Weather Research and Forecasting (WRF) model with different spatial resolutions in reproducing the spatial, seasonal, and diurnal characteristics of the near-surface air temperature and precipitation as well as the spatial shifts in the diurnal monsoonal precipitation peak over the Khumbu (Everest), Rolwaling, and adjacent southern areas. Therefore, the ERA-Interim (0.75°) reanalysis has been dynamically refined to 25, 5, and 1 km (D1, D2, and D3) for one complete hydrological year (October 2014–September 2015), using the one-way nested WRF model run with mild nudging and parameterized convection for the outer but explicitly resolved convection for the inner domains. Our results suggest that D3 realistically reproduces the monsoonal precipitation, as compared to its underestimation by D1 but overestimation by D2. All three resolutions, however, overestimate precipitation from the westerly disturbances, owing to simulating anomalously higher intensity of few intermittent events. Temperatures are generally reproduced well by all resolutions; however, winter and pre-monsoon seasons feature a high cold bias for high elevations while lower elevations show a simultaneous warm bias. Unlike higher resolutions, D1 fails to realistically reproduce the regional-scale nocturnal monsoonal peak precipitation observed in the Himalayan foothills and its diurnal shift towards high elevations, whereas D2 resolves these characteristics but exhibits a limited skill in reproducing such a peak on the river valley scale due to the limited representation of the narrow valleys at 5 km resolution. Nonetheless, featuring a substantial skill over D1 and D2, D3 simulates almost realistic shapes of the seasonal and diurnal precipitation and the peak timings even on valley scales. These findings clearly suggest an added value of the convective-scale resolutions in realistically resolving the topoclimates over the central Himalayas, which in turn allows simulating their interactions with the synoptic-scale weather systems prevailing over high Asia.
Administering Justice and Serving the People

Administering Justice and Serving the People
Canada has a complex system of courts that seek to serve Canadians in view of the traditional objectives of civil justice – principally accessibility, efficiency, fairness, efficacy, proportionality and equality. The Canadian court system is generally considered by its users to work well and to have legitimacy. Yet, researchers have found that ‘there is a tendency for people involved in a civil case to become disillusioned about the ability of the system to effect a fair and timely resolution to a civil justice problem’. This article will discuss the ways in which reforms of procedural law and civil justice have originated and continue to be made throughout Canada, both nationally and provincially, as well as the trends and influences in making these reforms. With hundreds of contemporary procedural reforms having been discussed, proposed and/or completed since the first days of Canadian colonisation on a national basis and in the Canadian provinces and territory, providing a detailed analysis will prove challenging. This article will nonetheless provide a review of civil justice and procedural reform issues in Canada, focusing principally, at the provincial level, on the systems of Ontario and Quebec. Importantly, I will seek to reconcile the increasing willingness to have an economically efficient civil justice and the increased power of judges in managing cases, with our court system’s invasion of ADR and its prioritisation of informal modes of adjudication.
