MATERIAL CHARACTERIZATION OF CERAMIC TILE MOSAIC FROM TWO 17TH‐CENTURY ISLAMIC MONUMENTS IN NORTHERN INDIA

Coloured tiles from two northern Indian monuments were analysed for their body and glaze composition. The results suggest that three different groups of tiles were used, all comprising a stonepaste body with alkali glaze. One group has strong similarities to a major Indian glass group, known as high alumina mineral natron glass, while the other two are similar to Western and Central Asian plant ash glazes, although with much lower lime content. The colorants conform with those usually employed in pre‐modern glazes, with lead‐tin yellow Type I and Type II for opaque yellow, copper blue‐turquoise, cobalt blue, manganese purple, and green through mixing of lead‐tin yellow and copper blue.     

EPISTEMIC WOUNDED ATTACHMENTS: RECOVERING DEFINITIONAL SUBJECTIVITY THROUGH COLONIAL LIBRARIES

Postcolonial theorizing on empires and subjects focuses on governance and infrastructure as relevant geographies of relation. However, when governance-driven knowledge production migrates from colony to metropole, what postcolonial subjectivity formations are recovered from colonial archives, particularly if these archives are structured by epistemic difference? We theorize a wounded attachment to a colonial library, or the construction of subjectivity through colonial archival recovery, as a means of transforming a colonial library of governance into an academic discipline. Through the case study of Sikh studies, a discipline originating out of colonial governance of Sikhs, we argue that epistemic difference is transformed into epistemic distancing as a tool by which scholars pursue legibility to the Euro-American academy. We contextualize the ongoing investment in measures of academic legibility (for example, objectivity, distance, and validity) as how area and region are tied to the production of universal knowledge; these measures result in the elision of embodied knowledge as a valid framework for intellectual pursuit.     

ÉVOLUTION DE L'AGRICULTURE MARAÎCHÈRE AU QUÉBEC DE 1940 À 1990: SUPERFICIES,PRODUCTIONS ET DIVERSITÉ

Depuis plus d'un siècle, l'agriculture québécoise en général, et la production maraîchère en particulier, ont subi d'importantes transformations. Cette étude historique vise à comprendre comment la production maraîchère a évolué par rapport aux changements dans l'environnement décisionnel général de l'agriculture entre 1940 et 1990. L'analyse des données statiques de superficie, de production et de rendement pour 12 légumes ont permis d'identifier trois périodes, intercalées d'années transitoires, dans l'évolution de la production maraîchère référant chacune à une stratégie agricole particulière. La première (1940–1957) correspond à une stratégie agricole de type familial traditionnel; la seconde (1963–1975), à une agriculture marchande spécialisée fondée sur la maximisation des revenus à court terme par intensification; la troisième (1980–1990), à une agriculture marchande diversifiée fondée également sur une maximisation à court terme. Les facteurs externes de l'environnement décisionnel qui ont entraîné ces changements sont identifiés et discutès. For more than a century, Quebec agriculture in general, and market-gardening production in particular, have experienced important changes. This study, using a historical perspective, seeks to understand how market gardening evolved in relation to changes in the broad decision environment for agriculture between 1940 and 1990. Statistical analysis of data on the areas cultivated, production levels, and yields for 12 vegetable crops revealed three distinct periods, separated by periods of transition, in the evolution of market gardening. Each period is characterized by a particular type of agricultural development strategy. The first period (1940–1957) is characterized by a focus on the traditional family form; the second (1963–1975), by a specialized market agriculture driven by short-term income-maximization intensification; the third (1980–1990), by a diversified marketoriented agriculture, also based on short-term income maximization. External environmental factors that stimulated these changes are identified and discussed.     

LE RÉCHAUFFEMENT DU CLIMAT TERRESTRE ET LES IMPACTS POTENTIELS EN GÉOGRAPHIE DES MALADIES

Selon la plupart des modèles théoriques du climat futur, la température moyenne à l'échelle du globe devrait augmenter de 2 à 4°C dans les prochaines décennies. Les conséquences du réchauffement de la température pourraient avoir des effets sur les activités humaines, et sur la santé humaine. Dans cet article nous décrivons les effets directs sur la santé, maladies dues à la chaleur, et les effets indirects concernant les maladies à vecteurs. Les scénarios sur la croissance des décès à la suite des vagues de chaleur, et sur la diffusion des insectes vecteurs des maladies soulèvent des problèmes conceptuels et méthodologiques qui devront être résolus dans le futur si l'on veut que les résultats provenant de divers pays puissent être comparés et évalués.
Based on climate simulations by general circulation models (GCMS), mean global temperature is expected to rise by 2 to 4°C in coming decades. Such a global warming can have significant impacts on human activities, including human health. In this article, we describe the direct effects of increasing temperature on human health. Secondary effects of the influence of temperature on vector-borne diseases are also described. Different scenarios relating to increase in mortality deriving from heat waves and from the spread of diseases through insect vectors pose conceptual and methodological problems that must be confronted in the future if comparative studies are to be undertaken concerning the effect of global warming on human health in different countries.     

THERE IS NO COLONIAL RELATIONSHIP: ANTAGONISM,SIKHISM, AND SOUTH ASIAN STUDIES

This article identifies how scholars have displaced antagonism within histories of Sikhism and South Asian Studies more broadly. In contrast to this displacement, this article foregrounds antagonism by taking into account a third element within the presumed colonizer and colonized relationship: a curved space of nonrelation that signals there can be no colonial relationship. By considering the constitutive nature of antagonism within social reality that remains unable to be demarcated, this article examines the generative principles of Sikh practices and concepts that both structure Sikhism's institutions and productively conceptualize this antagonism. Examining these concepts and practices, I consider the possibility of different modes of both historical being and becoming not bound within our current conceptual rubrics. These different possibilities culled through Sikh concepts and theories demand we reflect upon the rabble: those unable to be contained within colonial civil society or within attempts by the colonized for self‐determination in political societies. This void then fractured Sikh reform organizations historically, providing multiple avenues for politics unaccountable within our bifurcated and asymmetrical understandings of civil society and political societies and colonizer and colonized.     

EFFECTS OF SOIL LAYERING ON THE CHARACTERISTICS OF BASIN-EDGE INDUCED SURFACE WAVES AND DIFFERENTIAL GROUND MOTION

This paper studies the effects of soil layering in the basin based on the characteristics of basin-edge induced surface waves and associated differential ground motion. Seismic responses of various basin-edge models were simulated using software based on parsimonious finite difference staggered grid approximation of 2.5D eiastodynamic wave equation. Seismic responses of various models with different number of soil/soft rock layers but for a fixed thickness of deposit, fundamental frequency and impedance contrast revealed a decrease of surface wave amplitude with an increase in the number of layers in the basin. Shifting of dominant frequency towards the higher values was obtained with an increase of number of layers. An increase of dispersion of surface waves with an increase of number of soil layers in the basin was observed. A minor increase of Rayleigh wave velocity with an increase of number of soil layers was also obtained, but in the case of Love wave it was almost negligible.

Spectral analysis of the edge-induced surface waves revealed that the anomalous earthquake intensity may arise in a zone of width of 2.5–3.0 km, parallel to basin-edge and at an offset of 0.5–0.7 km from the edge. Maximum horizontal differential ground motion (HDGM) developed by Love wave (≈4.9×10^?2) was more than that of Rayleigh wave (≈9.4×10^?3). Large variation in HDGM caused by the surface waves was obtained with a change in the number of layers in the basin and maximum HDGM was observed when there were only two layers in the basin. It was inferred that the effect of soil layering in the basin was more on the Rayleigh wave as compared to the Love wave. Development of large HDGM near the basin-edge and its dependency on the number of soil layers reveals that basin-edge induced surface waves need special attention during seismic microzonation or seismic hazard prediction.
