The Everyday Occupation of Space by Teenagers in a Deprived Neighbourhood: Conflict Without Mobilisation
Authors: Danic Isabelle 
Published: July 2012

ABSTRACTAround the world, there is increasing concern with the ways in which different populations use public spaces and places. Focusing on the French context, this paper investigates conceptual difficulties inherent in the co‐occupation of space by different population groups. The focus is to shed light on the ordinary engagement of teenagers in a working‐class neighbourhood in terms of differentiated social practices according to gender, age, social network, the physical and social morphology of the neighbourhood, and relational and situational criteria. Their occupation of space is channelled by public policies as well as educational, family, and socio‐educational care that structure their time and space. However, this paper highlights also the subjective dimension. Manipulating the ‘regime of familiarity’ and the ‘regime of regular planning’, teenagers learn through experimentation to use the ‘regime of justification’, thus challenging adult spatiality in terms of their moral and political involvement.The deliberate and involuntary characteristics of their occupation of space transgresses the accepted uses of public space and disturbs adults. Their actions produce discomfort, which adult residents express through distancing practices. Teenagers recall various situations of general dissatisfaction that they are unable to synthesise in a complaint with reference to a general problem, and they express this feeling through stronger transgressions. Low‐level conflict between adults and teenagers is thus self‐perpetuated.Furthermore, teenagers' occupation of space is differentiated between girls and boys, between the ‘cool’ teenagers and the ‘geeks’, the teenagers from the neighbourhood and those from the outside, those who ‘have origins’ and those who do not. This generates unpleasant reciprocal disturbance and an everyday conflict that is further perpetuated by the failure to frame this disturbance as a public problem.

Authors: Guivant José , Cossell Stephen , Whitty Mark , Katupitiya Jayantha 
Published: July 2012

AbstractThe problem of remote‐controlling a mobile robot through the Internet with its associated bandwidth constraints is addressed in this paper. Our solution combines a novel communication and processing module with a unique sensor layout and a flexible control architecture to achieve a range of capabilities from traditional teleoperation to point‐and‐click autonomy. Careful management of the available bandwidth enables a demonstration of these capabilities between nodes with 20,000 km separation while also providing real‐time three‐dimensional (3D) models of the environment through the Internet. A spatially oriented compression algorithm, integral to efficient bandwidth management, is also presented. Experiments establish the effectiveness of the extended situational awareness in improving the efficiency and accuracy of driving a mobile robot through a cluttered environment over the existing 2D map or video streaming methods. © 2012 Wiley Periodicals, Inc.
Acquisition announcements and stock market valuations of acquiring firms' rivals: A test of the growth probability hypothesis in China
Authors: Gaur Ajai S. , Malhotra Shavin , Zhu Pengcheng 
Published: July 2012

AbstractTo examine the impact of acquisition announcements on the stock market returns of rivals of the acquiring firms, we propose a growth probability hypothesis: when an acquisition is announced, it signals the potential for future growth in the acquirer's industry to the market, resulting in positive stock market reactions to rivals of the acquiring firms. We test the growth probability hypothesis with a longitudinal sample of Chinese domestic and cross‐border acquisitions during 1993–2008. The results provide robust support for this hypothesis as a means to explain market reactions to rivals of acquiring firms. We also empirically test and negate alternative theoretical explanations advanced in prior literature to explain positive market reactions to rivals of the target firms.

Hollow Copper Sulfide Nanoparticle‐Mediated Transdermal Drug Delivery
Authors: Ramadan Samy , Guo Liangran , Li Yajuan , Yan Bingfang , Lu Wei 
Published: July 2012

AbstractA photothermal ablation‐enhanced transdermal drug delivery methodology is developed based on hollow copper sulfide nanoparticles (HCuSNPs) with intense photothermal coupling effects. Application of nanosecond‐pulsed near‐infrared laser allows rapid heating of the nanoparticles and instantaneous heat conduction. This provides very short periods of time but extremely high temperatures in local regions, with focused thermal ablation of the stratum corneum. The depth of skin perforations can be controlled by adjusting the laser power. Skin disruption by HCuSNP‐mediated photothermal ablation significantly increases the permeability of human growth hormone. This technique offers compelling opportunities for macromolecular drug and vaccine delivery.
Effects of Salt Tracer Amount, Concentration and Kind on the Fluid Flow Behavior in a Hydrodynamic Model of Continuous Casting Tundish

Published: July 2012

AbstractThe hydrodynamic modeling method that widely used to simulate the fluid flow was reconsidered and discussed in this paper. The effects of injected salt tracer amount, concentration and kind on the fluid flow behavior in a hydrodynamic model tundish were investigated. The results were compared with the mathematical modeling calculation results, that the tracer density effect was eliminated. The residence time distribution (RTD) curve of tracer introduced deviated to the left side of the calculated curve, besides the deviation was increased as dimensionless tracer amount (the ratio of tracer amount to hydrodynamic model tundish volume) increased from 0.202 × 10−3 to 1.008 × 10−3. The results of tracer concentration study were similar, namely the deviation was increased with concentration increased; on the other hand, the deformation of a “stair‐shape” RTD curve occurred when tracer concentration was much lower (at dimensionless tracer amount of 0.168 × 10−3 with converting to saturated solution). Besides, the effect of tracer kind on the accuracy of hydrodynamic modeling was also studied; the measurements of KCl solution with lower density than that of NaCl solution exhibited more of accuracy. Finally, the optimized tracer in hydrodynamic model tundish of present work is saturated KCl solution with dimensionless tracer amount of 0.202 × 10−3.
US East Coast offshore wind energy resources and their relationship to peak‐time electricity demand
Authors: Dvorak Michael J. , Corcoran Bethany A. , Ten Hoeve John E. , McIntyre Nicolas G. , Jacobson Mark Z. 
Published: July 2012

ABSTRACTThis study characterized the annual mean US East Coast (USEC) offshore wind energy (OWE) resource on the basis of 5 years of high‐resolution mesoscale model (Weather Research and Forecasting–Advanced Research Weather Research and Forecasting) results at 90 m height. Model output was evaluated against 23 buoys and nine offshore towers. Peak‐time electrical demand was analyzed to determine if OWE resources were coincident with the increased grid load. The most suitable locations for large‐scale development of OWE were prescribed, on the basis of the wind resource, bathymetry, hurricane risk and peak‐time generation potential. The offshore region from Virginia to Maine was found to have the most exceptional overall resource with annual turbine capacity factors (CF) between 40% and 50%, shallow water and low hurricane risk. The best summer resource during peak time, in water of ≤ 50 m depth, is found between Long Island, New York and Cape Cod, Massachusetts, due in part to regional upwelling, which often strengthens the sea breeze. In the South US region, the waters off North Carolina have adequate wind resource and shallow bathymetry but high hurricane risk. Overall, the resource from Florida to Maine out to 200 m depth, with the use of turbine CF cutoffs of 45% and 40%, is 965–1372 TWh (110–157 GW average). About one‐third of US or all of Florida to Maine electric demand can technically be provided with the use of USEC OWE. With the exception of summer, all peak‐time demand for Virginia to Maine can be satisfied with OWE in the waters off those states. Copyright © 2012 John Wiley & Sons, Ltd.
Winter waterbird and food dynamics in autumn‐managed moist‐soil wetlands in the Mississippi Alluvial Valley
Authors: Hagy Heath M. , Kaminski Richard M. 
Published: July 2012

AbstractManaged moist‐soil wetlands are important habitats for waterfowl and other waterbirds in the Mississippi Alluvial Valley (MAV) and elsewhere in North America. These wetlands often contain abundant food resources, but they also contain tall and dense (i.e., robust) vegetation that may constrain use and foraging by waterbirds. During winters 2006–2009, we estimated densities of waterbirds, seeds and tubers, and aquatic invertebrates following autumn, preflooding treatments of disking, mowing, and no manipulation (control) of robust vegetation in 26 moist‐soil wetlands in and near the MAV. In late autumn, seed and tuber dry mass was greater in control ( = 750.7 kg/ha) and mowed ( = 709.7 kg/ha) than disked plots ( = 509.8 kg/ha). Dabbling ducks (Anatini) accounted for 92% of all waterbirds observed and were 2–3 times more abundant in mowed and disked than control plots during winter. Invertebrates comprised <1% (dry mass) of potential waterbird foods, but were greatest in control plots throughout winter. In mid‐ and late winter, residual seed and tuber masses were similar among mowed, disked, and control plots within study sites (approx. 260 kg/ha), despite different waterbird use. We recommend 1) active management of moist‐soil wetlands, including partial autumn mowing of robust vegetation to increase use by waterbirds; 2) that conservation planners consider increasing foraging thresholds (e.g., giving‐up density) in carrying‐capacity models for moist‐soil wetlands; and 3) additional experiments to describe foraging thresholds in moist‐soil and other wetlands targeted by the North American Waterfowl Management Plan. © 2012 The Wildlife Society.
Spatial Evaluation of Groundwater Quality in Kazhakuttam Block, Thiruvananthapuram District, Kerala
Authors: Binoj Kumar R.B. , Divya M.P. 
Published: July 2012

Abstract
The groundwater in the study area generally shows an acidic trend as evidenced by the low pH values, particularly in lateritic aquifers. Spatial assessment indicates that the southern part of the coastal aquifers shows elevated pollution levels during post monsoon season. Most of the groundwater is of Na-Cl facies in post monsoon and which slightly changes to Na-Mg-Cl facies during pre monsoon. Inter relationship between chemical parameters were also studied to understand the groundwater facies. Salinity hazard, percentage of sodium, SAR, integrated SAR and EC and RSC, were considered for judging the usefulness of groundwater for irrigation. Landuse map was prepared and water sample locations were superimposed on it, in a GIS platform, to assess the variation in water quality in different landuse classes. The outcome of the present study indicates that the concentration of certain parameters exceeds the recommended limits and hence mitigation measures are needed to be adopted to ensure safe drinking water.
Evaluation and Augmentation of Safe Drinking Water Supply Schemes in Salur Mandal, Vizainagaram District, Andhra Pradesh
Authors: Mondal Nepal C. , Das Surendra N. 
Published: July 2012

Abstract
In order to assess the groundwater potentiality and augmentation of water supply schemes, estimation of the safe yield, well loss, formation loss, horse power of pump, depth of pump installation and duration of the pumping are essential. These parameters are estimated either by means of in-situ test or laboratory test. But the applicability of result from the laboratory test has limitations while in-situ tests give real representation of individual well of aquifer. The most common in-situ test is pumping test performed on well, which involves measurement of the fall and rise of water level with respect to time. The changes in water level (drawdown/recovery) and its quality are caused due to pumping of water from the well. Such study was carried out in Salur Mandal, Vizainagaram, Andhra Pradesh, India.
In this study, special emphasis was given to the step draw down test at 13 bore wells with maximum 4-steps preferably increasing discharge rate (ranges: 24-293 lpm) for the intensification of safe drinking water supply. Simultaneously 26 groundwater samples were collected separately in 2 steps of the pumping phases from each well and then chemically analyzed. This study indicates that the recommended yields varied from 3600 to 12000 lph. The wells could be used in safely with recommended yield of 5000 lph and pumped for 1 to 2 hrs in 4 to 8 hrs intervals per day. Groundwater is of nearly neutral to mildly acidic and alkaline nature in the pumping stresses. The total dissolved solids (TDS) varied from 142-1050 mg/l, but its values changed from –67 to 240 mg/l during the pumping phases. The concentrations of chloride and sulphate changed from –20 to 30 mg/l and –2 to 8 mg/l, respectively, but about 39% groundwater samples are of constant Cl-concentration. In these pumping phases groundwater is hydrochemically within permissible limit for drinking water supply. This study provides the basis of safe drinking water to tribals, backward class communities and school children.
Tectonic Amalgamation of Crustal Blocks along Gadag-Mandya Shear Zone in Dharwar Craton of Southern India
Authors: Sengupta Siladitya , Roy Abhinaba 
Published: July 2012

Abstract
The crustal scale Shear Zone that can be traced from Gadag in the north to Mandya in the south in Dharwar Craton of southern India is considered as the boundary between two subcratonic blocks namely the Eastern Dharwar Craton (EDC) and the Western Dharwar Craton (WDC) in published literature. The present study on the Gadag-Mandya Shear Zone (GMSZ) in the Javanahalli-Hagalvadi sector has brought out a detailed account on the disposition, geometry and kinematics of the shear zone, and also the distinctive structural patterns of the two adjacent supracrustal belts, namely the Chitradurga schist belt (CSB) in the west and Javanahalli schist belt (JSB) in the east. The JSB has an overall N-S striking and gentle easterly dipping geometry, the structural features of which are indicative of a predominant non-coaxial deformation and westward transportation of the supracrustal assemblage. In contrast, deformation in the CSB, which is defined mainly by a flattening type of strain, has produced an overall verticality of the structures (dominant foliation, axial planes of regional folds).
Difference in metamorphic grade is apparent from the mineral assemblages in the rocks of these two belts, while the JSB showing an amphibolite facies CSB is restricted to green schist facies mineral assemblages.
The 2 to 3 km wide, N-S striking, prominent ductile shear zone, GMSZ, has affected both CSB and JSB rocks and also the syntectonically emplaced Bukkapatna granite. The geometric and kinematic evidences from both the belts and the GMSZ point to an E-W horizontal compressional regime. The gentle dipping, amphibolite grade JSB and its underlying gneisses acted as an allochthon which got amalgamated with the subvertical, green schist grade CSB by a top-W thrusting along the GMSZ. The subvertical CSB impeded further up-dip movement of the eastern block, resulting in the subsequent development of N-S trending sinistral strike slip shear along the contact of the two contrasting belts to accommodate the continued E-W compression. The linear Bukkapatna Granite, synkinematically emplaced along GMSZ shows evidences of both magmatic stage and solid state deformation in the shear zone.
Biogenic Wad in Iron Ore Group of Rocks of Bonai-Keonjhar Belt, Orissa
Authors: Mohapatra B. K. , Mishra S. , Singh P. P. 
Published: July 2012

Abstract
Outcrop of wad, about 3-5 m thick, associated with low to medium-grade manganese ore deposits in Iron Ore Group (IOG), is present in large quantum in Bonai-Keonjhar belt, Orissa. It is often inter-bedded with volcanic ash layers. Wad is powdery, fine grained, black to blackish-brown in colour, very soft, readily soils the fingers and its hardness on the Mohs’ hardness scale is 1-3. The wad zone is capped by a thin lateritic zone and overlies manganese ore beds of variable thickness in Dalki, Guruda and Dubna mines. Wad constitutes two mineral phases, viz. manganese oxides (δ-MnO2, manganite, romanechite with minor pyrolusite) and iron oxides (goethite/limonite and hematite) with minor clay and free quartz. Mixed limonite-clay and cryptomelane-limonite are commonly observed. Under microscope the ore appears oolitic, pisolitic, elipsoidal to globular in shape having small detritus of quartz, pyrolusite /romanechite and hematite at the core. The ore contains around 23% Mn and 28% Fe with ~7% of combined alumina and silica. Wad might have developed in a swampy region due to slow chemical precipitation of Fe-Mn-Co enriched fluid, nucleating over quartz/hematite grains. Influence of a marine environment is indicated from δ-MnO2 phase. Remnants of some microfossils, like algal filament, bacteria, foraminifera and diatomite are observed in wad sample under SEM. These microorganisms might have been responsible for the oxidation of dissolved Mn2+ and Fe2+ precipitates. These findings suggest bio-chemogenic origin of wad in Bonai-Keonjhar belt of Orissa.
Optimization of Analytical Equations of Groundwater Seepage into Tunnels: A Case Study of Amirkabir Tunnel
Authors: Farhadian H. , Aalianvari A. , Katibeh H. 
Published: July 2012

Abstract
In this study, with investigation of validity limits of analytical equations in computing groundwater seepage discharge into tunnels in different values of r/h (tunnel radius/water table height above tunnel), using optimization by regression analysis, we have tried to converge the results of analytical equations for any value of r/h. There are various experimental, analytical and numerical methods by which it is possible to calculate the amount of groundwater seepage into tunnels. Due to their simplicity and practical base theory, analytical methods have been applied more frequently. Studies imply that amount of real seepage into tunnel is significantly less than what is anticipated from analytical equations; on the other hand, the results of seepage calculations using these equations are depended on tunnel geometry and medium conditions. Previous investigations confirmed that in a tunnel for which, r/h is more than 0.4; these results are highly different both from one another and from the real seepage inflow. In this paper, optimization has been successfully performed on analytical equations so that the results of these methods are converged to each other for any value of r/h.
Early Permian Xiphosurid Trackways from India
Authors: Chakraborty Abhijit , Bhattacharya H. N. 
Published: July 2012

Abstract
Present work is the first report of Early Permian xiphosurid trackways from India. Surface trackways and undertracks, preserved within ice-marginal storm-affected, shoreface sediments of the Talchir Formation, Jayanti coalbasin closely resemble Kouphichnium Nopsca 1923. Trackways reveal distinct heteropody with foliate pusher impressions, paired series of semi-circular, oval, V- or Y-shaped chilate (walking) leg impressions. Varied ventral impressions also include telson drag marks and telson dents; spine drag marks, book -gills impression, genal gouges as well as symmetric, paired lateral genal furrows, partial cubichnial impressions of prosoma and spinose opisthosoma. A tentative early Permian age (Asselian/Sakmarian) and marginal marine facies association points towards a paleolimuloidae affinity for the trace makers, which is in conformity with their inferred widths of exoskeleton, sub-rounded prosoma and subtriangular spinose opisthosoma with predictable movable spines. Flexed pusher impressions and co-dominant pincer impressions as well as, other ventral impressions in abundance, confirm crawling as their dominant mode of locomotion. Inferred presence of juvenile crawlers in the community suggests a probable shoreline or marginal marine ecospace.
