Morphological and Stratigraphical Significance of Lower Gondwana Plant Fossils of Mohpani Coalfield, Satpura Gondwana Basin, Madhya Pradesh
Authors: Srivastava A. K. , Saxena Anju , Agnihotri Deepa 
Published: December 2012

Abstract
Plant fossils from the coal bearing Barakar Formation exposed in Gottitoria open cast mine of Mohpani Coalfield, Satpura Gondwana Basin are described for the first time. The assemblage is represented by Glossopteris communis, G. indica, G. stenoneura, Gangamopteris angustifolia, G. cyclopteroides, G. karharbariensis, G. major, seeds of Cordaicarpus zeilleri and equisetaceous stems. The dominance of the species of Gangamopteris over the species of Glossopteris and absence of Noeggerathiopsis indicate the floral affinity with the flora of Lower Barakar Formation of Lower Gondwana.

Published: December 2012

Abstract
The present study was undertaken with four fold objectives, namely, (i) to estimate land surface temperature using MODIS TIR data; (ii) to calculate relative emissivities from MODIS TIR data; (iii) to identify various lithologies based on relative emissivity and land surface temperature estimation; and finally, (iv) to carry out comparative assessment analysis between the prepared lithological map and the published lithological map. The land surface temperatures for different pixels were estimated using two methods, viz., Reference Channel and Emissivity Normalization; whereas, relative emissivities were calculated by applying three methods, viz., Reference Channel, Emissivity Normalization and Alpha Residual. Lithological maps were subsequently prepared based on the estimated land surface temperatures and relative emissivity values. The present study shows that the Emissivity Normalization method gives the best results for land surface temperature estimation and also for lithological discrimination based on emissivity estimation. Twenty-four lithounits demarcated by the present study match with those of the published map, while four lithounits of the published map could not be identified in the present study. On the other hand, six additional unclassified lithounits could be demarcated in the present study, which need to be crosschecked by field study.
Environmental Isotopic Evaluation of the Springs Located in Kazan Trona Basin in Central Turkey
Authors: Arslan Sebnem , Yazicigil Hasan 
Published: December 2012

Abstract
Kazan Trona ore field, the second discovered deposit in Central Turkey, is planned to be extracted by solution mining technology. Understanding the hydrogeology of the springs in such an area is vital since they can be affected during mining operations. The aim of this study is to provide an isotopic approach by utilizing environmental isotope techniques to the springs in the study area, thereby, to enhance the understanding of their occurrence by complementing the previous geochemical studies. Here, the isotopic signatures and the recharge elevations of the springs are demonstrated together with their field parameters. The relationship between δD and δ18O suggest strong evaporation in some of the samples after recharge. For those springs, the unmodified signatures were determined and the recharge elevations were calculated to be between 1100 and 1248 m. These elevations correspond to Incirlik and Asmalidere Members and upper Neogene units. The relationship between Tritium and Electrical Conductivity suggested that SP-6, SP-3 and SP-4 have shallow circulation when compared to SP-7 having both the lowest tritium and highest EC value. This finding is in accordance with the geochemical data, which suggests SP-7 emerges from the deeper, older groundwater present above the trona deposit.
Distinct Ruby Suite at Sardapur, Orissa: A Spectroscopic Investigation
Authors: Majumdar Alik Sundar , Mathew George 
Published: December 2012

Abstract
Orissa is an important area for gem variety of corundum deposits in India. Spectroscopic studies, such as ESR, OAS on samples from Sardapur, Orissa, were carried out to ascertain the colour cause of corundum. Electron spin resonance (ESR) spectroscopic study was carried out on the samples to detect the presence of paramagnetic ions i.e. Fe2+, Fe3+, Ti4+, Cr3+ and V3+ etc. The variable temperature experiment carried out to observe the effect of heating on peak valence state change in paramagnetic ions. Samples were cut and polished to obtain the optical absorption spectrum (OAS) to detect the colour causing transition ions/defect centres. The samples of gem variety were step heated up to 300°C for colour enhancement studies. EPMA analysis has revealed the low chromium concentration in the rubies. The varying hues of red in the corundum are due to the presence of bivalent and trivalent iron and charge transfer process along with Cr3+ absorption in the 550 nm region.
Kinematic and Dynamic Analysis of North-Tehran Tectonic Wedge Formed in South Central Alborz, Iran
Authors: Rajabi Sareh , Eliassi Mohsen 
Published: December 2012

Abstract
To answer the question “Whether the North-Tehran tectonic wedge is a dynamic tectonic wedge or not?” we applied paleostress techniques to investigate fault slip data. The mean reduced stress tensor is defined for all stabilized stress regions. Unscaled Mohr’s circles drawn for fault slip data were used to obtain the relative slip tendency of clusters on diagrams. It showed that the slip tendency in the vicinity of fault junction is much lower than expected. The mean σ1 defined for a combination of fault slip data trends N14°E nearly parallel with the overall pressure in Iranian crust at the latitude of Central Alborz. This trend suggests the least effect of boundary faults and the wedge between them on stress orientations inside the wedge. Finally, the stress trajectory map was prepared showing the configuration and relative intensity of σ1. The map did not illustrate any convergence in σ1 trajectories and the consequent concentration of stress and seismic potential in fault junction. That is a direct evidence for disagreeing the dynamicity of this tectonic wedge.
Centralizers of rank-one homeomorphisms
Authors: HILL AARON 
Published: December 2012

AbstractWe give a definition for a rank-one homeomorphism of a zero-dimensional Polish space X. We show that if a rank-one homeomorphism of X satisfies a certain non-degeneracy condition, then it has trivial centralizer in the group of all homeomorphisms of X, i.e. it commutes only with its integral powers.

SCFA provide energy to the host and influence lipid and glucose metabolism, suggesting that they may have an impact on the occurrence of metabolic risk factors. The aim of the present study was to determine the concentration of SCFA in faeces of lean and obese individuals and to analyse whether associations between faecal SCFA and metabolic syndrome parameters are present. Lean (n20) and obese (n20) women of similar age (28·5 (sd7·6)v.30·7 (sd6·5) years,P= 0·33) participated in the study. Anthropometric measurements, body composition, blood pressure and biochemical parameters were assessed. SCFA were extracted from faeces and quantified by GC. Blood pressure and blood glucose, although within the normal limits, were higher in the obese group compared to lean subjects (P< 0·05). Lower HDL concentration and higher insulin and homeostasis model assessment (HOMA) index were observed in the obese than in the lean group (P< 0·05). The median values of SCFA (% w/w) from the lean and obese groups were butyric (0·021v.0·044,P= 0·024), propionic (0·021v.0·051,P= 0·007) and acetic (0·03v.0·061,P= 0·01). SCFA correlated positively with metabolic syndrome risk factors such as adiposity, waist circumference and HOMA index (P< 0·05), and inversely with HDL (P< 0·05). Our results suggest that the higher faecal concentration of SCFA is associated with metabolic risk factors and thus may influence metabolic homeostasis.
The Role of Anchoring Bias in the Equity Market: Evidence from Analysts’ Earnings Forecasts and Stock Returns
Authors: Cen Ling , Hilary Gilles , Wei K. C. John 
Published: December 2012

AbstractWe test the implications of anchoring bias associated with forecast earnings per share (FEPS) for forecast errors, earnings surprises, stock returns, and stock splits. We find that analysts make optimistic (pessimistic) forecasts when a firm’s FEPS is lower (higher) than the industry median. Further, firms with FEPS greater (lower) than the industry median experience abnormally high (low) future stock returns, particularly around subsequent earnings announcement dates. These firms are also more likely to engage in stock splits. Finally, split firms experience more positive forecast revisions, more negative forecast errors, and more negative earnings surprises after stock splits.
Delayed endovascular coil extrusion after embolisation for post-tonsillectomy haemorrhage: case report and literature review
Authors: Fassnacht W , Hammer F , Gardiner Q , Desuter G 
Published: December 2012

AbstractObjective:To report a rare case of delayed endovascular coil extrusion following embolisation of a lingual artery pseudoaneurysm.Case report:A 23-year-old woman presented with dysphagia and odynophagia 11 months after having experienced massive post-tonsillectomy haemorrhage. At that time, the bleeding had been stopped by embolisation of a lingual artery pseudoaneurysm and the external carotid artery. Clinical examination at admission showed extrusion of the embolisation coils in the lateral lower pharyngeal wall. The coils were removed under general anaesthesia in the presence of an interventional radiologist. The procedure and post-operative period were without complication and no bleeding was observed. The dysphagia and pain disappeared and the subsequent seven-month follow-up period was uneventful.Conclusion:Although selective embolisation is a safe and effective treatment for severe post-tonsillectomy haemorrhage, the possibility of delayed coil extrusion should be kept in mind.
Experiences of neighbourhood exclusion and inclusion among older people living in deprived inner-city areas in Belgium and England
Authors: BUFFEL TINE , PHILLIPSON CHRIS , SCHARF THOMAS 
Published: December 2012

ABSTRACTThis article explores conceptual and empirical aspects of the social exclusion/inclusion debate in later life, with a particular focus on issues of place and space in urban settings. Exploratory findings are reported from two empirical studies in Belgium and England, which sought to examine experiences of social exclusion and inclusion among people aged 60 and over living in deprived inner-city neighbourhoods. Semi-structured interviews were conducted with an ethnically diverse sample of 102 older people in Belgium and 124 in England. Thematic analysis of interview data identifies four issues in relation to the neighbourhood dimension of social exclusion/inclusion in later life: experiences of community change; feelings of security and safety; the management of urban space; and strategies of control. The results suggest that neighbourhoods have a significant influence on shaping the experience of exclusion and inclusion in later life, with a number of similarities identified across the different study areas. The article concludes by discussing conceptual and policy issues raised by the research.
Intergenerational solidarity and old-age support for the social inclusion of elders in Mainland China: the changing roles of family and government
Authors: DU PENG 
Published: December 2012

ABSTRACTChina's population has been ageing rapidly since the 1980s, with 178 million older persons (60 years or over) in 2010 and 450 million expected by 2050. The sheer size of the ageing population means that there is an urgent need to tackle ageing issues and improve social policies in order to achieve intergenerational solidarity, sustainable development and a harmonious society. This paper will summarise the issues and debates in the past decade on social exclusion and discuss the progress of policies and practices with respect to social inclusion. The focus of discussion will be on (a) ways to improve the social security system so as to achieve a better balance of formal and informal supports, (b) development of community services for meeting the needs of older people living alone or having special needs in daily living, and (c) new initiatives for balancing formal support and filial piety, taking into account the younger generation's expectation that in order to maintain the important role of filial piety in modern China, the ability to fulfil filial obligations must be supported by the development of formal support beyond the family. In addition, some emerging issues and challenges will also be discussed.

AbstractObjectivePercutaneous transcatheter occlusion has benefited thousands of patients suffering from patent foramen ovale and atrial septal defect. However, no general agreement has been reached on the superiority among occluders. Thus, a meta-analysis between the two most commonly adopted types of occluders was conducted.MethodsThe literature review has identified relevant studies up to May, 2011 in the databases of PubMed, EMBASE, the Cochrane Central Register of Controlled Trials, and World Health Organization clinical trials registry centre. Meta-analysis was performed in a fixed/random effects model using Revman 5.1.1. Information on complications and outcomes was extracted.ResultsAnalysis from included studies reports an outcome in favour of the Amplatzer. The Amplatzer has proven its superiority in efficacy with a significantly lower risk of early (95% confidence interval = 0.09–0.34) and long-term (95% confidence interval = 0.14–0.97) residual shunt rate for atrial septal defect occlusion, although no significant difference in performance has been reported for patent foramen ovale. In addition, the Amplatzer has also remarkably reduced the risk of embolisation by the device (95% confidence interval = 0.07–0.45) for atrial septal defect and new-set atrial fibrillation (95% confidence interval = 0.18–0.48) for patent foramen ovale. On evaluation of recurrent thrombotic events, it was found that the Amplatzer greatly lowered the rate of thrombus formation on the device (95% confidence interval = 0.02–0.21) for patent foramen ovale; however, no statistical difference was found on atrial septal defect evaluation. However, the result indicated no statistically significant difference between the two kinds of occluders in stroke and transient ischaemic attack of patent foramen ovale.ConclusionThe meta-analysis has proven the Amplatzer to be the superior occluder, serving better prognosis with more fluent procedure and less complications.

ObjectiveThe need for symmetry and ordering objects related to a “just right”-feeling is a common symptom in Tourette's syndrome (TS) and resembles symmetry behavior in obsessive-compulsive disorder, but its pathophysiology is unknown. We used a symptom provocation paradigm to investigate the neural correlates of symmetry behavior in TS and hypothesized the involvement of frontal-striatal and limbic brain areas.MethodsPictures of asymmetrically and symmetrically arranged objects were presented in randomized blocks (4 blocks of each condition) to 14 patients with TS and 10 matched healthy controls (HC). A H215O positron emission tomography scan was acquired during each stimulus block, resulting in 8 scans per subject. After each scan, state anxiety and symmetry behavior (the urge to rearrange objects) were measured using a visual analogue scale.ResultsDuring the asymmetry condition, TS patients showed increased regional cerebral blood flow (rCBF) in the anterior cingulate cortex, supplementary motor area, and inferior frontal cortex, whereas HC showed increased rCBF in the visual cortex, primary motor cortex, and dorsal prefrontal cortex. Symmetry ratings during provocation correlated positively with orbitofrontal activation in the TS group and sensorimotor activation in the HC group, and negatively with dorsal prefrontal activity in HC.ConclusionsResults suggest that both motor and limbic circuits are involved in symmetry behavior in TS. Motor activity may relate to an urge to move or perform tics, and limbic activation may indicate that asymmetry stimuli are salient for TS patients. In contrast, symmetry provocation in HC resulted in activation of brain regions implicated in sensorimotor function and cognitive control.
What Makes An Important Case? An Agenda for Research
Authors: Morison John 
Published: December 2012

AbstractThis paper is drawn from a presentation, by John Morison, that was made to a plenary session of the 43rd BIALL Annual Study Conference in Belfast, Northern Ireland 2012. The presentation introduced the audience to a research study, recently funded by the Economic and Social Research Council, entitled “What Makes an ‘Important Case’? A Study of the Creation, Transmission and Validation of Legal Knowledge”, and being carried out with Professor Gordon Anthony. The presentation to BIALL also attempted to engage the audience of legal information specialists with the specifics of the project and enlist their help in understanding how an important aspect of legal practice actually works. This paper has the same objective, and, additionally, it reports on some of the initial findings of the research which aims to develop a comprehensive sociology of legal knowledge.
From Oxford to Williamsburg: Part 1 – The University of Oxford, Faculty of Law and Bodleian Law Library
Authors: Bird Ruth 
Published: December 2012

AbstractThe Bodleian Law Library has only existed as an entity in its own right for less than 50 years. Yet part of the collection dates back to the days before the founding of the Bodleian Library in 1602. The rise and fall in fortunes of the teaching of law at Oxford is closely tied to the establishment of the law library. A lesser known aspect of the history includes the ties between Oxford and the United States, especially its oldest law school, William and Mary Law School. In this paper, Ruth Bird offers a brief history of the University of Oxford and then looks at the history of law teaching, before moving on to the evolution of the Law Library itself, and some links with our cousins across the pond.

Published: December 2012

RhoGTPases are GDP/GTP molecular switches that control a wide variety of cellular processes, thereby contributing to many diseases, including cancer. As a consequence, there is great interest in the identification of small-molecule inhibitors of RhoGTPases. In the present paper, using the property of GTP-loaded RhoGTPases to bind to their effectors, we describe a miniaturized and robust assay to monitor Rac1 GTPase activation that is suitable for large-scale high-throughput screening. A pilot compound library screen revealed that the topoisomerase II poison MTX (mitoxantrone) is an inhibitor of Rac1, and also inhibits RhoA and Cdc42 in vitro. We show that MTX prevents GTP binding to RhoA/Rac1/Cdc42 in vitro. Furthermore, MTX strongly inhibits RhoGTPase-mediated F-actin (filamentous actin) reorganization and cell migration. Hence, we report a novel biochemical assay yielding the identification of RhoGTPase inhibitors and we present a proof-of-concept validation with the identification of MTX as a novel pan-RhoGTPase inhibitor.

Published: December 2012

Human RBM25 (RNA-binding motif protein 25) is a novel splicing factor that contains a PWI domain, a newly identified RNA/DNA-binding domain, and regulates Bcl-x pre-mRNA alternative splicing. The flanking basic region has been suggested to serve as a co-operative partner of the PWI domain in the binding of nucleic acids, but the structure of this basic region is unknown. In the present paper, we report the crystal structure of the RBM25 PWI domain and its flanking basic region. The PWI domain is revealed to comprise a conserved four-helix bundle, and the flanking basic region forms two α-helices and associates with helix H4 of the PWI domain. These interactions promote directly the formation of an enlarged nucleic-acid-binding platform. Structure-guided mutagenesis reveals a positively charged nucleic-acid-binding surface in the RBM25 PWI domain that is entirely different from that in the SRm160 PWI domain. Furthermore, we show that the promotion of the pro-apoptotic Bcl-xS isoform expression by RBM25 is facilitated by the PWI domain in vivo. Thus the present study suggests that the PWI domain plays an important role in the regulation of Bcl-x pre-mRNA alternative splicing.
Reproductive failure of a long‐lived wetland tree in urban lands and managed forests
Authors: McCauley Lisa A. , Jenkins David G. , Quintana‐Ascencio Pedro F. 
Published: December 2012

Urbanization is associated with the eventual reproductive failure of cypress and in the absence of management practice changes, cypress recruitment may cease in many additional wetlands. If past urbanization rates continue, 80–90% of cypress populations in isolated wetlands in the path of urban sprawl could permanently cease recruitment in 100 years. Reducing urban sprawl and introducing prescribed fire in managed‐forest cypress domes could mitigate this effect and conserve reproduction of this long‐lived, dominant tree species and the diversity of the wetlands they typify.
