Rise of Red Terror: The Ethics and Effectiveness of Maoist Violence in India
No full textThe University Archives has determined that this item is of continuing value to OSU's history.The media can be accessed here: http://streaming.osu.edu/knowledgebank/mershon10/043010.mp4Sangeeta Mahapatra is a Fulbright-Nehru Doctoral and Professional Research Fellow. As a visiting scholar at the Mershon Center for International Security Studies, she is currently working on a comparative study of counterterrorism strategies of India, Israel and the United States. As Mahapatra argues, the core of counterterrorism is capability. While states may set for themselves certain goals, how far they are able to deliver on them determines the strengths and weaknesses of their counterterrorism strategy. The aim of the study is to expand the scope of counterterrorism decision-making by studying how the three countries use their political, legal, civilian and economic structures to deal with an outlier event. The question is not about expending a lot of resources on a "high risk-low probability" threat but about responding to it in timely, cost-efficient and effective manner. Mahapatra is the author of Pacification of the Irreconcilable: The Israeli-Palestinian Conflict (Kolkata, 2005) and Miasma: A Collection of Short Stories (Chowringhee Prakashini Press, Kolkata, 1999).

Spinal dysraphism controversies: AIIMS experiences and contribution
No full textA large series of split cord malformation (SCM). Over the last 22 years, we have operated more than 1500 patients of SD, of which over 450 are (SCM), and 300 are with various lipomatus malformations. About 55% type II and 45% type I SCM. A separate sub-classification of type I SCM (a,b,c and d), is presented which alter the surgical approach and influence the results. Overall improvement following surgery in patients with SCM was observed in 94%. Fifty percent patients improved and 44% remained stable. However, deterioration was noticed in 6%, mostly with composite type of SCM. A paradigm for management of SCM is provided taking into consideration also the author′s large experience
Geodetic network design for InSAR: Application to ground deformation monitoring
No full textFor the past two decades, interferometric synthetic aperture radar (InSAR) has been used to monitor ground deformation with subcentimetric precision from space. But the applicability of this technique is limited in regions with a low density of naturally-occurring phase-coherent radar targets, e.g. vegetated nonurbanized areas. Third-party end-users of InSAR survey results cannot, in a systematic way, determine a priori whether these coherent targets have adequate spatial distribution to estimate the parameters of their interest. Additionally, InSAR deformation estimates are referred to a local datum, meaning that the technique is sensitive only to the relative deformation occurring within the SAR images. This makes it difficult to compare these estimates with those from other techniques, e.g. historical levelling data or changes in the sea level. Here we propose the design of a geodetic network for InSAR, aimed at densifying the naturally-occurring measurement network and converting from a local datum to a global one. A practical solution for improving spatial sampling is to deploy coherent target devices such as corner reflectors or transponders on ground, tailored to the specific monitoring application under consideration. The proposed method (1) provides a generic description of any deformation phenomenon; (2) determines whether the naturally-occurring InSAR measurements are adequate in terms of user-defined criteria; (3) finds the minimum number of additional devices to be deployed (if required); and (4) finds their optimal ground locations. It digests, as inputs, any prior knowledge of the deformation signal, the expected locations and quality of the existing coherent targets, and the quality of the deployed devices. The method is based on comparing different covariance matrices of the final parameters of interest with a criterion matrix (i.e., the ideal desired covariance matrix) using a predefined metric. The resulting measurement network is optimized with respect to precision, reliability and economic criteria; this is demonstrated via synthetic examples and a case of subsidence in the Netherlands. As a basis for the choice and number of deployed devices, we evaluate the measurement precision of compact active transponders and demonstrate their viability as alternatives to passive corner reflectors through three field experiments, using different satellite data and geodetic validation techniques. Transponders are shown to be usable for subcentimetre-precision geodetic applications, while improving upon the drawbacks of corner reflectors in terms of size, shape, weight and conspicuousness. For transforming the spatially-relative InSAR deformation estimates (local datum) to a standard terrestrial reference frame (global datum), we introduce a new concept involving the collocation of transponders with Global Navigation Satellite System (GNSS) measurements. The displacement of such a transponder is consequently determined in the standard reference frame used by GNSS, eliminating the need for any assumptions on reference-point stability in applications where the InSAR deformation estimates are compared with results from other techniques. The considerations, results and practical lessons learnt at several permanent GNSS stations in the Netherlands are described.Geoscience and Remote SensingCivil Engineering and Geoscience
Silicate cloud formation in the atmospheres of close-in super-Earths and gas giants
No full textContext: Clouds form in the atmospheres of brown dwarfs and extrasolar planets. Recent observations of planets orbiting extremely close (<0.1 AU) to their stars indicate possible atmospheres with silicate compositions resulting due to vaporization of silicate magma from their surface. Such atmospheres are heavily dependent on compositions of the planetary crust which in turn might influence the kind of dust particles that form in such atmospheres. Aims: We identify five types of silicate compositions commonly found on Earth and derive atmospheric chemistry with Earth silicates as starting compositions using an equilibrium chemistry atmospheric model. Following the mineral cloud modelling approach for hot atmospheres of brown dwarfs and giant gas planets, we model the dust cloud formations resulting due to varying Earth silicate compositions and apply that to investigate the possibility of clouds on sample atmospheres of a giant gas planet, 55 Cnc e, HD149 026b and CoRoT-7b. Methods: Atmospheric compositions for the planets have been derived using a previously validated Equilibrium chemistry code. We derive our atmospheric chemistry using element abundances from previously studied Earth surface compositions which is provided as an input to the 1D kinetic cloud formation model, DRIFT. We perform cloud modelling on each of the atmospheres with varying silicate compositions and study the resulting cloud properties such as particle growth, particle sizes and their composition at various stages. Results: We present the cloud structures resulting due to varying Earth silicate compositions on four different types of planets. The clouds show variations in the dust properties due to different starting compositions with differing average particle sizes but the formation conditions such as average particle size, cloud thickness and condensation altitude largely remain dependent on the local gas density and temperature. The cloud layers on 55 Cnc e, HD149 026b are found to be greatly varying in terms of their geometrical thickness, particle sizes and number densities and are primarily composed of silicates of elements such as Mg, Si, Fe and Al.Aerospace EngineeringSpace Engineerin
Metal sulfide-based nanomaterials for electrochemical CO<sub>2</sub> reduction
No full textThe electrochemical CO2 reduction (ECO2R) is critical to enabling the widespread use of abundant renewable energy sources. However, in order to successfully implement such technologies on an industrial scale, necessary advancement in both the material and molecular design of electrocatalysts is required. In recent years, metal-sulfide (MS)-based nanomaterials have been explored as promising electrocatalysts for ECO2R. This article provides a systematic review of the design and development of MS-based catalysts for ECO2R, including their synthesis, characterization, reaction mechanism, catalytic performance, and strategies for future optimization. The current state-of-the-art MS-based ECO2R catalysts and their technical challenges are outlined herein with the purpose of establishing new guidelines for the rational design of next generation MS-based catalysts for CO2 electroreduction.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.ChemE/Materials for Energy Conversion and Storag
