Putting the selfie to work: Image making and work/time discipline in the margins of the Indian state
No full textIn India, the use of biometric images as a means of evidencing whether workers or schoolchildren are present is becoming increasingly prevalent. By exploring how the capturing of images has become a key feature of organizing the work-time discipline in Delhi, this chapter shows that narratives about the state implementing infrastructures of digital surveillance from above as part of regimes of techno-moral governance only provide a partial account. Surveillance also emerges from below as managers and outsourced workers operating in the margins of the state repurpose ubiquitous messaging services such as WhatsApp to create informal networks of visibility. Within these networks, selfies—and other images—take on a significance and purpose rather at odds with the feelings of pleasure, leisure, and self-expression more often associated with their digital circulation and begin to reveal the everyday, even banal, ways in which regimes of transparency, accountability, and work/time discipline are produced

Influence of the tip gap size on the development of the tip-leakage vortex using Large Eddy Simulations
No full textIn hydraulic turbines, the tip-leakage vortex is responsible for flow instabilities and for promoting erosion due to cavitation. To better understand the flow in the tip region, LES computations are carried out to compute the flow around a NACA0009 blade including the gap between the tip and the wall. The influence of the gap size is investigated by computing two gap widths. The validation of the results is performed by comparisons with experimental data. The simulations are also used to investigate the flow in the tip gap region. Depending on the gap width, the vortex flow topology differs from one case to the other. At large gap widths, the tip-leakage vortex merges with the tip-separation vortex. On the contrary, at small gap widths, the tip-leakage vortex move upward and no tip-separation vortex is clearly identified. Part of these observations are validated by comparisons with experimental visualizations of the cavitating tip-leakage vortex
The Pursuit of The Arabic Language Issues, by Germanos Farhat: Editions and Translation
No full textGermanos Farhat (1670-1732) foi um bispo maronita em Alepo e importante estudioso da língua árabe. Dedicou-se ao estudo do árabe e produção de obras literárias, catequéticas e linguísticas na língua, a fim de estimular seu pleno domínio pelos maronitas, que até então usavam o siríaco como língua litúrgica. Uma de suas obras mais importantes, escrita em 1705, foi \"Em busca de questões da língua árabe\", que circulou amplamente nas escolas otomanas até o início do século XX, com diversas edições. Germanos se propôs a produzir um material de estudo gramatical para os cristãos ao mesmo tempo substancial e de fácil compreensão, de modo que pudessem dominar facilmente o árabe. Foi tão bem-sucedido em seu objetivo que \"Em busca de questões da língua árabe\" chegou a ser utilizado por importantes nomes do Renascimento Árabe (Nahḍa), como Buṭrus al- Bustāni, Sacīd aš-Šartūnī e Nāṣīf al-Yāzijī. A obra é organizada em três livros: \"Livro primeiro: flexão dos verbos\", \"Livro segundo: flexão dos nomes\", e \"Livro terceiro: sintaxe\", utilizando como corpus a própria Bíblia. O autor divide cada livro em seções, que são divididas em pesquisas e estas, por sua vez, em questões, em que Germanos discutirá os principais aspectos desses três assuntos. Esperando bem apresentar a obra, este trabalho tem o objetivo de: (a) comparar as edições de Sacīd aš-Šartūnī (1882), Buṭrus al-Bustānī (1854) e Tobia Mtīnī (1857); e (b) fazer uma tradução comentada da \"Introdução pelo Autor\" e da seção \"Das Frases\", do terceiro livroGermanos Farhat (1670-1732) was a Maronite bishop in Aleppo and an important scholar of the Arabic language. He engaged in Arabic language studies and writing literary, catechetical, and linguistic works in that language to encourage its mastery by the Maronites, who until then had used Syriac as a liturgical language. One of his most relevant works, which was written in 1705, was \"The Pursuit of the Arabic Language Issues\", widely circulated in Ottoman schools until the beginning of the 20th century, with several editions. Germanos intended to write a grammar study material for Christians that was both substantial and easy to understand, so they could easily master Arabic. He was so successful in his purpose that \"The Pursuit of the Arabic Language Issues\" was used by important names of the Arab Renaissance (Nahḍa), such as Buṭrus al- Bustāni, Sacīd aš-Šartūnī and Nāṣīf al-Yāzijī. The work is organized into three books: \"Book First: Inflection of Verbs\", \"Book Second: Inflection of Nouns\", and \"Book Third: Syntax\", using examples from the Bible as corpus. The author divides each book into sections, which are divided into pursuits and then into questions, in which Germanos will discuss the main aspects of these three subjects. Attempting to well present Farhat\'s work, this paper aims to: (a) compare the editions of Sacīd aš-Šartūnī (1882), Buṭrus al-Bustānī (1854) and Tobia Mtīnī (1857); and (b) make a commented translation of the \"Introduction by the Author\" and the section \"On Phrases\", of the third boo
Soil Nutrient Availability, Plant Nutrient Uptake, and Wild Blueberry (Vaccinium angustifolium Ait.) Yield in Response to N-Viro Biosolids and Irrigation Applications
No full textWe compared the impact of surface broadcasted N-Viro biosolids and inorganic fertilizer (16.5% Ammonium sulphate, 34.5% Diammonium phosphate, 4.5% Potash, and 44.5% s and/or clay filler) applications on soil properties and nutrients, leaf nutrient concentration, and the fruit yield of lowbush blueberry under irrigated and nonirrigated conditions during 2008-2009 at Debert, NS, Canada. Application rates of N-Viro biosolids were more than double of inorganic fertilizer applied at a recommended N rate of 32 kg ha−1. The experimental treatments NI: N-Viro with irrigation, FI: inorganic fertilizer with irrigation, N: N-Viro without irrigation, and F: inorganic fertilizer without irrigation (control) were replicated four times under a randomized complete block design. The NI treatment had the highest OM (6.68%) followed by FI (6.32%), N (6.18%), and F (4.43%) treatments during the year 2008. Similar trends were observed during 2009 with the highest soil OM values (5.50%) for NI treatment. Supplemental irrigation resulted in a 21% increase in the ripe fruit yield. Nonsignificant effect of fertilizer treatments on most of the nutrient concentrations in soil and plant leaves, and on ripe fruits yield reflects that the performance of N-Viro was comparable with that of the inorganic fertilizer used in this study
A numerical study of unsteady cavitation on a hydrofoil by les and URANS method
No full textIn this paper, the unsteady cavitation phenomena on a NACA0015 hydrofoil is numerically simulated by unsteady Reynolds-Averaged Navier-Stokes (URANS) method and Large Eddy Simulation (LES) in single-fluid approaches to multiphase modelling, respectively. It is observed that the large-scale structures and characteristic periodic shedding predicted by the URANS with the modified SST k-ω turbulence model show a good qualitative match with the experimental observations but with quantitative discrepancies, such as a different cavity length and volume, and a different location of shedding. Compared to the URANS results, the LES results reproduce more details of unsteady dynamics with an improved quantitative agreement.Ship Hydromechanics and Structure
The First Sentences of the French Author Mobasan's Stories.
No full textThis study reviews the importance of the first sentences in the first and second parts of (stories and novels) for the French author Mobasan. Why did we choose these parts? Because we could collect the first sentences in 31 stories divided into two parts, the first part includes 17 stories and the second one includes 14 stories. There are various topics in the two parts as Mobasan reviews scenes of everyday life, for example: the concept of death, lying, greed, tragedy and so on.
Mobsan depends on the descriptive style in reviewing these scenes, and usually the first sentences of Mobasan's stories have great effect on the characters and morals of his stories
Homogeneity in patterns of climate extremes between two cities: A potential for flood planning in relation to climate change
No full textInformation about potential scenarios and causes of floods is important for future planning. Historical weather data of Fredericton (New Brunswick) and Charlottetown (Prince Edward Island), the two coastal cities of Atlantic Canada, were analyzed using RClimDex, Mann–Kendall test, and Sen’s slope estimates for potential scenarios and causes of floods. Flood hazard analyses were conducted using GIS (Geographical Information System) and ArcSWAT software. The watersheds of Fredericton and Charlottetown were delineated from 25 × 25 m resolution DEMs (Digital Elevation Models) of the two cities followed by percent watershed area calculations for different elevation classes for flood generation. Over the past 100 years, there was a significant decreasing trend in the high intensity precipitation in Charlottetown supported by a significant decrease in the number of heavy precipitation days. However, maximum one-day precipitation and maximum five-day precipitation significantly increased in Charlottetown and Fredericton, respectively. Charlottetown received more annual precipitation than Fredericton. In the last 30 years, there was an event exceeding 50 mm precipitation (considered as a threshold for the return period of urban floods) in Charlottetown; Fredericton experienced such events for more than 1.5 times. For twelve times, these events occurred more than once in a year in Charlottetown as compared to fourteen times in Fredericton. Despite statistically proven similarities in the occurrence of extreme events in the two cities, the visualized flood hazards, and the mapping of watershed characteristics, no devastating floods were reported for Charlottetown. This does not necessarily mean that there had never been risks of flooding in Charlottetown. These findings may help policymakers for future developments.Natural Sciences and Engineering Research Council of Canad
Computation of Evapotranspiration with Artificial Intelligence for Precision Water Resource Management
No full textAccurate estimation of reference evapotranspiration (ETo) provides useful information for water resource management and sustainable agriculture. This study estimates ETo with recurrent neural networks (RNNs), namely long short-term memory (LSTM) and bidirectional LSTM. Four representative meteorological sites (North Cape, Summerside, Harrington, and Saint Peters) were selected across Prince Edward Island (PEI), Canada to form a PEI dataset from mean values of the four sites’ climatic variables for capturing climatic variability from all parts of the province. Based on subset regression analysis, the highest contributing climatic variables, namely maximum air temperature and relative humidity, were selected as input variables for RNNs’ training (2011–2015) and testing (2016–2017) runs. The results suggested that the LSTM and bidirectional LSTM are suitable methods to accurately (R2 > 0.90) estimate ETo for all sites except Harrington. Testing period (2016–2017) root mean square errors were recorded in range of 0.38–0.58 mm/day for all sites. No major differences were observed in accuracy of LSTM and bidirectional LSTM. Another objective of this study was to highlight the potential gap between ETO and rainfall for assessing agriculture sustainability in Prince Edward Island. Analyses of the data highlighted that the cumulative ETo surpassed the cumulative rainfall potentially affecting yield of major crops in the island. Therefore, agriculture sustainability requires viable options such as supplemental irrigation to replenish the crop water requirements as and when needed
