Nationalist Hindi Cinema
NATIONALIST HINDI CINEMA: QUESTIONS OF FILM ANALYSIS AND HISTORIOGRAPHY The forty years or so from the beginning of cinema world-wide at the end of the nineteenth century to the consolidation of a domestic film industry in South Asia in the 1930s coincided with the project of nation-building that envisioned a variety of horizons, and with the sedimentation of some of those prospects into the coalition ready to inherit the rule from the British Raj. Cinema played a crucial role in mediating the terms by which India came into being as a modern nation. As Ernest Gellner saw it, it is the homogenizing effect of an economic system such as industrial capitalism, and, within it, the occupational mobility and the division of labour leading to the breaking down of pre-industrial, hierarchical, self-contained social categories, that lead to the "invention" of nationalism. With the advent and spread of capitalism, "culture is..

This short essay considers how scholarship of South Asian cinema has advanced knowledge of low-budget, popular film genres (such as action, horror and porn films) beyond South Asian film studies
Expressing Without Asserting in the Arts
Critical debate as well as uncertain or subjective claims are pivotal elements in arts scholarly analysis.
Asserting such statements in RDF is hindered by the correct representation of uncertain or evolving aspects. In this article we examine and discuss the need and usefulness of expressing without asserting (EWA) arbitrary claims as RDF named graphs. We examine effectiveness of prior approaches to EWA and we propose a solution, called conjectures, to express and retrieve statements whose truth value is not specified

Site-directed spin labelling of proteins is routinely performed using nitroxides, with paramagnetic metal ions and other organic radicals gaining popularity as alternative spin centres. Spectroscopically orthogonal spin labelling using different types of labels potentially increases the information content available from a single sample. When analysing experimental distance distributions between two nitroxide spin labels, the site-specific rotamer information has been projected into the distance and is not readily available, and the contributions of individual labelling sites to the width of the distance distribution are not obvious from the PDS data. Here, we exploit the exquisite precision of labelling double-histidine (dHis) motifs with CuII chelate complexes. The contribution of this label to the distance distribution widths in model protein GB1 has been shown to be negligible. By combining a dHis CuII labelling site with cysteine-specific nitroxide labelling, we gather insights on the label rotamers at two distinct sites, comparing their contributions to distance distributions based on different in silico modelling approaches and structural models. From this study, it seems advisable to consider discrepancies between different in silico modelling approaches when selecting labelling sites for PDS studies.Publisher PDFPeer reviewe
Reserve Accumulation Is Prioritized Over Growth Following Single or Combined Injuries in Three Common North American Urban Tree Species
Trees that grow in urban areas are confronted with a wide variety of stresses that undermine their long-term survival. These include mechanical damage to the crown, root reduction and stem injury, all of which remove significant parts of plant tissues. The single or combined effects of these stresses generate a complex array of growth and ecophysiological responses that are hard to predict. Here we evaluated the effects of different individual and combined damage on the dynamics of non-structural carbohydrates (NSC, low weight sugars plus starch) concentration and new tissue growth (diameter increment) in young trees. We hypothesized that (i) tissue damage will induce larger reductions in diameter growth than in NSC concentrations and (ii) combinations of stress treatments that minimally alter the "functional equilibrium" (e.g., similar reductions of leaf and root area) would have the least impact on NSC concentrations (although not on growth) helping to maintain tree health and integrity. To test these hypotheses, we set up a manipulative field experiment with 10-year-old trees of common urban species (Celtis occidentalis, Fraxinus pennsylvanica, and Tilia cordata). These trees were treated with a complete array of mechanical damage combinations at different levels of intensity (i.e., three levels of defoliation and root reduction, and two levels of stem damage). We found that tree growth declined in relation to the total amount of stress inflicted on the trees, i.e., when the combined highest level of stress was applied, but NSC concentrations were either not affected or, in some cases, increased with an increasing level of stress. We did not find a consistent response in concentration of reserves in relation to the combined stress treatments. Therefore, trees appear to reach a new "functional equilibrium" that allows them to adjust their levels of carbohydrate reserves, especially in stems and roots, to meet their metabolic demand under stressful situations. Our results provide a unique insight into the carbon economy of trees facing multiple urban stress conditions in order to better predict long-term tree performance and vitality

Exploitation of Tartary Buckwheat as Sustainable Ingredient for Healthy Foods Production
AbstractTartary buckwheat (Fagopyrum tataricum Gaertn) is a minor crop belonging to the Polygonaceae family that can be considered as sustainable crop thanks to its low input requirements. It is a pseudo-cereal known for its high healthy value related to antioxidant compounds present in its grains. For this reason it could be employed for the production of functional foods. This paper as well as reviewing about the agronomical and nutritional traits of buckwheat also provides the latest experimental results achieved by ENEA research activities
Stenotrophomonas maltophilia Phenotypic and Genotypic Diversity during a 10-year Colonization in the Lungs of a Cystic Fibrosis Patient
The present study was carried out to understand the adaptive strategies developed by Stenotrophomonas maltophilia for chronic colonization of the cystic fibrosis (CF) lung. For this purpose, 13 temporally isolated strains from a single CF patient chronically infected over a 10-year period were systematically characterized for growth rate, biofilm formation, motility, mutation frequencies, antibiotic resistance, and pathogenicity. Pulsed-field gel electrophoresis (PFGE) showed over time the presence of two distinct groups, each consisting of two different pulsotypes. The pattern of evolution followed by S. maltophilia was dependent on pulsotype considered, with strains belonging to pulsotype 1.1 resulting to be the most adapted, being significantly changed in all traits considered. Generally, S. maltophilia adaptation to CF lung leads to increased growth rate and antibiotic resistance, whereas both in vivo and in vitro pathogenicity as well as biofilm formation were decreased. Overall, our results show for the first time that S. maltophilia can successfully adapt to a highly stressful environment such as CF lung by paying a "biological cost," as suggested by the presence of relevant genotypic and phenotypic heterogeneity within bacterial population. S. maltophilia populations are, therefore, significantly complex and dynamic being able to fluctuate rapidly under changing selective pressures
