Distribution of some elements in Veronica scutellata L. from Bolu,Turkey: soil-plant interactions

Veronica scutellata L. occurs in moist and wet habitats, such as ponds, marshes and other wetlands. This study was conducted on this species to examine its mineral element uptake status in terms of interactions between soil and plant. Experimental materials were taken from the Southern coast of Black Sea at coordinates 40º36’N and 31º16’E at an altitude of 1400 m above sea level from Bolu – Turkey; using standard methods and plant (root, stem and leaf parts) and soil mineral element measurements (Al, B, Ca, Cu, Fe, K, Mg, Mn, Na, Ni and Zn) were done. During the study, ICP-OES was employed for the measurement of mineral elements. It was observed that considerable amounts of B, Ca, K, Mg, Mn, Na and Zn are accumulated by the plant

Motion capture and human pose reconstruction from a single-view video sequence

Cataloged from PDF version of article.We propose a framework to reconstruct the 3D pose of a human for animation from a sequence of single-view video frames. The framework for pose construction starts with background estimation and the performer's silhouette is extracted using image subtraction for each frame. Then the body silhouettes are automatically labeled using a model-based approach. Finally, the 3D pose is constructed from the labeled human silhouette by assuming orthographic projection. The proposed approach does not require camera calibration. It assumes that the input video has a static background, it has no significant perspective effects, and the performer is in an upright position. The proposed approach requires minimal user interaction. (C) 2013 Elsevier Inc. All rights reserved

Signatures for doubly-charged Higgsinos at colliders

Several supersymmetric models with extended gauge structures predict light doubly-charged Higgsinos. Their distinctive signature at the large hadron collider is highlighted by studying their production and decay characteristics.Comment: 3 pages, 4 figures, Latex. Submitted for SUSY 2008 proceeding

Sneutrino Dark Matter: Symmetry Protection and Cosmic Ray Anomalies

We present an R-parity conserving model of sneutrino dark matter within a Higgs-philic U(1)' extension of the minimal supersymmetric standard model. In this theory, the mu parameter and light Dirac neutrino masses are generated naturally upon the breaking of the U(1)' gauge symmetry. The leptonic and hadronic decays of sneutrinos in this model, taken to be the lightest and next-to-lightest superpartners, allow for a natural fit to the recent results reported by the PAMELA experiment.Comment: Revised to match the published version; 11 pages (2 column format), 1 table, 6 figures, to appear in PR

Photovoltaic nanocrystal scintillators hybridized on Si solar cells for enhanced conversion efficiency in UV

Cataloged from PDF version of article.We propose and demonstrate semiconductor nanocrystal based photovoltaic scintillators integrated on solar cells to enhance photovoltaic device parameters including spectral responsivity, open circuit voltage, short circuit current, fill factor, and solar conversion efficiency in the ultraviolet. Hybridizing (CdSe) ZnS core-shell quantum dots of 2.4 nm in diameter on multi-crystalline Si solar cells for the first time, we show that the solar conversion efficiency is enhanced 2 folds under white light illumination similar to the solar spectrum. Such nanocrystal scintillators provide the ability to extend the photovoltaic activity towards UV. (c) 2008 Optical Society of America

Battlespace diaspora: how the Kurds of Turkey revive, construct and translate the Kurdish struggle in London

Re-energising debates on the conceptualisation of diasporas in migration scholarship and in geography, this work stresses the important role that geographers can play in interrupting assumptions about the spaces and processes of diaspora

Battling with Memleket in London: The Kurdish Diaspora's Engagement with Turkey

Since the late 1980s there has been a significant migration of Kurds from Turkey to the various countries in Western Europe. Even though Kurds from Turkey make up a significant proportion of London’s ethnic minority population, they constitute an ‘invisible’ diasporic community, both in terms of the current debates surrounding ethnicity and the Muslim minority in the UK and in diaspora studies. This article examines how the Kurdish diaspora interacts with, and relates to, their country of origin by highlighting their resistance to, and struggle with, Turkey (as defined by their displacement and suppression of cultural and linguistic rights) as well as the close and, at times, intimate ties Kurds continue to maintain with Turks and Turkey. Whilst the first is conceptualised as ‘battling with Turkey’, the latter is conceptualised within the framework of ‘memleket’ (homeland) ties. The article explores how the Kurdish diaspora encodes its orientation towards, as well as its resistance to, Turkey and in so doing, brings visibility to this largely ignored and understudied, yet politically very active, diasporic formation in London

Shedding an ethnic identity in diaspora: de-Turkification and the transnational discursive struggles of the Kurdish diaspora

This article analyses how Kurdish diaspora (from Turkey) engage in de-Turkification, that is correcting, interrupting and shedding the intense Turkification and assimilation which Kurds have been recipients of in Turkey. As ‘everyday critical discourse analysts’ Kurdish mobilized actors identify, challenge and ideologically unpack the Turkishness manifest in their (Kurdish) interlocutors’ discourses via three means: inclusion, exclusion and repositioning. The article also identifies that self-definition amongst Kurds in London is shifting as previously self-identified ‘Turkish economic migrants’ over time become ‘Kurdish diaspora’. Rather than examining the often-discussed belonging ties of diasporas, it traces the critical interruptions and corrections Kurdish actors undertake in order to de-Turkify. The focus is on how an identity is being shed, rather than gained. In so doing, the article contributes to an understanding of the process of removal of asymmetric discourses rather than attempting to demonstrate their production or reproduction which have tended to dominate the critical discourse analysis literature

The Global South as Foreignization: The Case of the Kurdish Diaspora in Europe

This article tilts the North/South axis of the Global South scholarship towards the East/West axis, specifically the Middle East and Kurds. I first re-visit the notion of the Global South by using the conceptual tools of translation studies, especially the notion of “foreignizing translation,” a strategy aimed at pushing the boundaries of the target language (and culture) rather than simply assimilating the translated text into it. Besides arguing that the Global South perspective concerns itself with questioning North-South relations temporally and spatially, I focus on the foreignizations diasporas can bring to the Global North. As both insiders and outsiders to Northern spaces, diasporas are uniquely placed both in terms of the foreignizations they bring to the Global North and the entanglements of the North and South which they expose. In this paper I examine the “Global South in the North” by taking the Kurdish diaspora living in European metropoles as a case study and conceptualizing the Kurdish movement as a transnational indigenous movement. I argue that through the foreignizations diasporas bring, the Global South is making claims not only in the North but also on the North. By focusing on the role of diasporas and the Middle East, areas which have received little attention within Global South scholarship, I seek to complicate and thus enrich our understandings of the Global South
