Pyroclastic Volcanism in Papaghni Sub-basin, Andhra Pradesh: Significant Paleoproterozoic Tectonomagmatic Event in SW Part of the Cuddapah Basin, Eastern Dharwar Craton
Authors: Sai V. V. Sesha 
Published: April 2014

Abstract:
Detailed field and petrological studies in Vanambayi-Lingala-Lopatnutala section and old Kadiri Ghat-Pulivendela section in SW part of the Proterozoic Cuddapah basin of Eastern Dharwar craton brought to light the occurrence of hitherto unreported two significant phases of pyroclastic volcanic activity associated with the Vempalle Formation in Papaghni sub-basin. Occurrence of a significant pyroclastic agglomerate at the contact zone of Vempalle dolomite of Papaghni Group and Pulivendela quartzite of Chitravathi Group represents a significant event of the mafic phase of pyroclastic volcanic activity, while the finely laminated felsic tuff within the intercalated reddish siltstone, chert and dolomite sequence in the lower part of Vempalle Formation represents the felsic phase of pyroclastic activity. Studies indicate that the pyroclastic agglomerate zone in Vanambayi-Lingala-Lopatnutala section is a classical example of pyroclastic volcanism wherein the highly vesicular rock with rounded basalt clasts often exhibit embayed contact of welded nature with the matrix. The pyroclastic zone reported in the present paper particularly at the interface of Vempalle Formation and Pulivendela quartzite in Vanambayi-Lingala-Lopatnutala section represents a significant tectono-magmatic event of explosive volcanic activity that is contemporaneous with the culmination of the carbonate precipitation of Vempalle dolomite and marks the termination of sedimentation in Papaghni Group in southwestern part of Cuddapah basin during Paleoproterozoic times.
Geochemistry of the Desur Lavas, Deccan Traps: Case Study from the Vicinity of Belgaum, Karnataka and their Petrogenetic Inferences
Authors: Hegde V. S. , Koti B. K. , Kruger S. J. 
Published: April 2014

Abstract:
Geochemical characteristics of Desur-type basalt flows in the southern and southwestern part of Belgaum in Karnataka, India have been investigated to understand their petrogenesis. The basalts are compact, hard, massive, and show characteristic microporphyritic textures with abundant well-twinned and un-twinned plagioclase phenocrysts and minor clinopyroxene set in a fine-grained groundmass consisting of plagioclase, clinopyroxene, glass and Fe-Ti oxides. Thin sections show sub-ophitic, intergranular and intersertal textures. The basalts are Fe-rich tholeiites (13.4-13.8 wt %), characterized by high TiO2 (3.64 to 3.94 wt %); moderate MgO contents (4.79 to 5.41 wt %), low K2O contents (&lt;0.58 wt %) and low Mg# (42.4-45.9). They are enriched in large ion lithophile elements, moderately enriched in the light rare earths (chondrite-normalized LaN/YbN 3.37-4.24), and exhibit nearly flat heavy rare-earth patterns that lack significant Eu anomalies (Eu/Eu* 0.86-1.10). Primitive-mantle-normalized element patterns for these rocks show characteristic troughs at K and Sr, absence of a Nb anomaly, and a low Zr/Nb ratio (&lt;15), which suggest insignificant contamination by many types of continental crust, whereas, enrichments in the large ion lithophiles, La, P and Th could suggest enriched source characteristics. Based on the geochemical characteristics of the basalts, it is inferred that the Desur basalts representing the youngest flows of the Deccan Basalt Group are derived by partial melting of a peridotite source, and subsequent fractionation gave rise to the compositions of the basalts that are found in the Belgaum region.
Mineral Magnetic Characterization of the Godavari River Sediments: Implications to Deccan Basalt Weathering
Authors: Kulkarni Y. R . , Sangode S. J. , Meshram D. C. , Patil S. K. , Dutt Yatindra 
Published: April 2014

Abstract:
Mineral magnetic analysis including thermo-magnetic studies and clay mineralogy on bed load and floodplain sediments from the Godavari river indicate distinct mineral assemblages. The floodplain sediments up to the delta region are characterised by unimodal ferrimagnetic mineralogy marked by the presence of maghemite and single domain magnetites derived from Deccan basalts. On the other hand the bed loads show varied magnetic mineral assemblages depicting greater local mixing from the non-basaltic bedrock province. The temperature dependent magnetic susceptibility and clay mineralogy of the floodplain samples show titanomagnetites (Fe3O4-Fe2TiO4), maghemite (χLF-Fe2O3) and smectite that are characteristic of the Deccan Volcanic Province (DVP). Presence of this ferrimagnetically dominant unimodal assemblage up to the delta region and probably into the Bay of Bengal off the Godavari river is attributed to extensive chemical weathering of the basalt. The quantitative approach of mineral magnetism, therefore, can be used to study the paleomonsoon variability and its relation to Deccan basalt weathering from the Godavari- Bengal fan system.

Authors: Raj K. Babu Govindha , Kumar K. Vinod , Mishra Rakesh , Mukhtar Muneer Ahmad 
Published: April 2014

Abstract:
The climate change of the twentieth century had an evident effect on glacier environments of the Himalaya. Temporal images of Indian Remote Sensing satellites provide an opportunity to monitor the recession of glacier and development of glacial lakes in the Himalayan cryosphere with a cost to time benefit ratio. The recession of Milam glacier and subsequent growth of a proglacial lake near the snout was analysed using Resourcesat-1 and Resourcesat-2 data. The recession of 480 m during 2004 to 2011 and growth of 47 epiglacial ponds over Milam glacier shows the glacier is in a state of imbalance and losing the ice by downwasting.
Basin Provenance and Post-Depositional Thermal History along the Continental P/T Boundary of the Raniganj Basin, Eastern India: Constraints from Apatite Fission Track Dating
Authors: Patel R.C. , Sinha H. N. , Kumar Bhaiya Anupam , Singh Paramjeet 
Published: April 2014

Abstract:
Apatite fission-track analysis has been applied to the Raniganj and Panchet formations of Raniganj basin of Gondwana Supergroup to unravel its thermal and provenance history. Apatite fission track age population from both Raniganj and Panchet formations indicate partial annealing and point to a maximum temperature of around ∼100-110°C during their post depositional evolution. The sandstone of Raniganj Formation has five peak ages at 26.3, 59.3, 109.7, 173.7 and 299.9 Ma, while Panchet Formation has three peak ages at 25.4, 143.5 and 281.3 Ma. This implies that the provenance of the Raniganj Formation of late Permian and Panchet Formation of early Triassic changed obviously. According to thermotectonic evolution of the Gondwana basin, these apatites with different FT ages possibly represent different source components, although partial annealing had occurred to these apatites. Possibly all the apatites had transported from the Precambrian basement which was undergoing deformation due to Gondwana rifting initiated during Carboniferous period. Due to this, the basement was undergoing inhomogeneous thermal history which became source of sediments for Raniganj basin.
Apatite FT ages of both Raniganj and Panchet formations have peak ages between 25 and 60 Ma, which perhaps recorded the cooling/uplift history during Cenozoic Alpine-Himalayan orogeny. Given a palaeo-thermal gradient of 40° C/km, it can be deduced that the Raniganj basin has uplifted about 3km at an average rate of about 0.09mm/a since 25-60 Ma.
Hydrocarbon Source Potential and Depositional Environment of the Surma Group Shales of Bengal Basin, Bangladesh

Published: April 2014

Abstract:
Surma Group is the most important geological unit of Bengal basin, Bangladesh, because petroleum resources occur within this group. It is mainly composed of alternation of shale and sandstone and the shale fraction has long been considered as source rocks and the sandstone fraction as reservoir. These source and reservoir rocks have been studied by different authors by different approach but none of them adopted organic geochemistry and organic petrology as a means of study of source rock and their possible depositional environment. A total of thirty shale core samples have been collected from eight different gas fields to fulfill the short coming. The collected samples have been subjected to Source Rock Analysis (SRA) and/or Rock-Eval (RE) followed by pyrolysis gas chromatography (PyGC), gas chromatography mass spectrometry (GCMS), elemental analysis (EA) and organic petrological study such as vitrinite reflectance measurement and maceral analysis.
The analyzed organic matter extracted from the shales of Surma Group consists mainly of Type III along with some Type II kerogen. The studied shales are mostly organically lean (TOC ±1%) and the extracted organic matter is fair to moderate. Based on these results, the analyzed shales have been ranked as poor (mostly) to fair quality source rock. The organic matter of the analyzed shale samples is thermally immature to early mature for hydrocarbon generation considering their Tmax and measured mean vitrinite reflectance values. The hopane 22S/(22S + 22R), moretane/hopane ratio and sterane parameters are also in good agreement with these thermal maturity assessments.
The predominance of odd carbons over even carbons (most common) and/or even carbons over odd carbon numbered n-alkanes, moderate Pr/Ph ratio, low to high Tm/Ts ratio, comparative abundance of sterane C29 (i.e., C29 &gt;C27&gt;C28), Pr/nC17 - Ph/nC18 values, C/S ratio and dominance of vitrinite macerals group with the presence of liptinite macerals demonstrate that the organic matter has derived mainly from terrestrial inputs with an insignificant contribution from the marine sources. The condition of deposition alternates from oxic to anoxic.

Published: April 2014

Abstract:
Geochemical composition (major and trace elements) of Miocene sandstones of the Surma Group exposed in Sitapahar anticline, Southeastern Bengal Basin was determined to reveal their provenance, tectonic setting and source area weathering conditions. The sandstones are sub-arkosic, sub-lithic and greywacke in composition with abundant low-grade metamorphic, sedimentary lithics (mainly chert with some shale fragments), low feldspars and little volcanic detritus. Compared to the average sandstone value, the Surma Group sandstones are depleted in CaO and enriched in Al2O3, Fe2O3 and Na2O. The Chemical Index of Alteration (CIA) values for the Miocene Surma Group sandstones vary from 57 to 73 with an average of 65, indicating low to moderate weathering of the source areas. The geochemical characteristics suggest an active continental margin to passive margin setting for the Surma Group sandstones; preserve the signatures of a recycled provenance that is agreement with sandstone petrography and derivation of these sandstones from felsic source rocks.

Published: April 2014

Abstract:
One of the major strengths of a GIS is the ability to integrate and combine multiple layers of geoscience data for producing mineral potential maps showing favorable areas for mineral exploration. Once the data is prepared properly, the GIS, jointly with other statistical and geostatistical software packages, can be used to manipulate and visualize the data in order to produce a mineral prospectivity map. Many spatial modeling techniques can be employed to produce mineral potential maps. This paper demonstrates a technique to define favorable areas for REE mineralization with AHP technique using geological, geochemical, geophysical, alteration and faults density spatial data in the Kerman-Kashmar Tectonic Zone of central Iran. The AHP is a powerful and flexible multi-criteria decision-making tool for dealing with complex problems where both qualitative and quantitative aspects need to be considered. This approach is knowledge-driven method and can be applied in other areas for conventional use in mineral exploration.
Is the pace/sense conductor related to a high voltage short circuit in a dual coil ICD system? An experimental study
Authors: Nakajima Hiroshi , Sutton Richard , Toyoshima Takeshi 
Published: April 2014

AbstractBackgroundWe carried out a bench study of implantable cardioverter‐defibrillator (ICD) performance in order to investigate whether the right ventricular (RV) ring contributes to the occurrence of a high‐voltage (HV) short circuit.MethodsA polycarbonate water bath with 0.18% saline was prepared. An ICD lead was connected to an ICD device and both were placed into the water bath. The impedance of each electrode and coil was measured. In the first experiment, the RV ring was shorted to the RV coil using an alligator clip. The impedance of each electrode and coil at shorting was measured. A maximum energy defibrillation shock was delivered. The therapy log confirmed the HV short circuit and the delivery conditions. In the second experiment, a short circuit was established between the RV ring and the superior vena cava coil and a similar procedure was followed.ResultsNo HV short circuit was observed in either experiment. Scheduled shock energies were delivered without problems. Some changes in pace–sense impedance or coil impedance were observed, but they remained within the normal range.ConclusionsThe RV ring conductor is not related to HV short circuits, even if the RV ring and/or RV ring conductor is placed in contact with HV electrodes.
“Language Which Will Move Their Hearts”: Speaking Power, Performance, and the Lay-Clerical Relationship in Modern Catholic Ireland
Authors: Delay Cara 
Published: April 2014

AbstractThis article explores the lay-clerical relationship in Catholic Ireland from 1850 to the 1930s through an analysis of oratory, rhetoric, and storytelling. It examines how words, speech, and storytelling constructed and complicated the lay-clerical relationship. The Catholic priest's spoken word was a valuable tool in his parish mission; by preaching and making announcements from the pulpit, he transmitted the ideas of Ireland's postfamine Catholic revival, known as the “devotional revolution,” to the laity. Yet as the Catholic Church came to dominate much of cultural life and the position of the parish priest expanded, he sometimes found his authority undermined by parishioners who challenged his clerical performances and who employed their own forceful words and long-standing oral traditions, including legends and storytelling, to qualify clerical power. As a result, the local existence of the Irish Catholic priest was complicated and contested, and the Catholic laity successfully tempered and moderated clerical power.
The Environmental Policy of Charles I: Coal Smoke and the English Monarchy, 1624–40
Authors: Cavert William M. 
Published: April 2014

AbstractEarly modern London burned quantities of dirty coal that were unparalleled anywhere in Europe before industrialization, and the consequent smoky air was a matter of more serious and sustained concern than has been appreciated by either early modern or environmental historians. During the 1620s and 1630s, King Charles I and his government sought to remove smoky industries, above all large brewhouses, from the vicinity of the court in Westminster. This was part of a broader campaign for order and beauty that has been described by other scholars, but a focus on smoke highlights the very partial successes achieved by attempts to reform the real spaces of royal government. The improvement of Westminster's air during Charles's personal rule displays an early modern variety of environmental concern that was expressed through courtly display, hierarchy, distinction, and exclusion.
Missing Women: Sex Ratios in England, 1000–1500
Authors: Bardsley Sandy 
Published: April 2014

AbstractThis article proposes that late medieval English men may have outnumbered women by a significant margin, perhaps as high as 110 to 115 men for every 100 women. Data from both documentary and archaeological sources suggest that fewer females survived to adulthood and that those who did may have died younger than their husbands and brothers. Historians of medieval England have said little about the possibility of a skewed sex ratio, yet if women were indeed “missing” from the population as a whole in a significant and sustained way, we must reinterpret much of the social, economic, gender, and cultural history of late medieval England.
Synthetic biology and the conservation of biodiversity
Authors: Redford Kent H. , Adams William , Carlson Rob , Mace Georgina M. , Ceccarelli Bertina 
Published: April 2014

AbstractSynthetic biology is a broad and fast-moving field of innovation involving the design and construction of new biological parts, and the redesign of existing, natural biological systems to address real world problems. It has many potential applications that may change human relations to the natural world. Synthetic biology is virtually unknown to the conservation community. Based on a meeting in 2013 that brought together these two communities we consider first the differences between the two fields, and second the kinds of opportunities and risks that arise.
Three-Dimensional Microvasculature in Rat and Human Hearts Using a Non-injection Ca2+-ATPase Method on Thick and Ultra-Thick Sections

Published: April 2014

AbstractCurrently there are no methods available for staining rat and human myocardial microvasculature on thick sections that would allow for specific staining and differentiation of arterioles, venules, and capillaries. A non-injection technique is described that allows for labeling of the microvascular bed (MVB) in formalin-fixed pieces of the myocardium from humans and the white ratRattus norvegicus, as well as human full-mount pericardium. Vessel staining is based on the activity of phosphatases (ATPases) and the precipitation of the released phosphate with calcium ions at high pH (pH 10.5–11.5). The resulting precipitate subsequently is converted to black or brown lead sulfide. The specificity of this reaction to vessels of the MVB allows arterioles, venules, capillaries, and pre- and postcapillaries to be clearly visualized in thick (60–100µm) and ultra-thick (300–500µm) sections against an unstained background of muscle and connective tissue. In addition, smooth muscle cells of arterioles are also stained allowing for differentiation between arteriolar and venular beds. These observations have not been reported in rat or human myocardium using other methods. This procedure should benefit studies of coronary microcirculation in experimental and pathological conditions, as well as in pharmacological investigations.
Quantifying quality in DNA self-assembly
Authors: Wagenbauer Klaus F. , Wachauf Christian H. , Dietz Hendrik 
Published: April 2014

AbstractMolecular self-assembly with DNA is an attractive route for building nanoscale devices. The development of sophisticated and precise objects with this technique requires detailed experimental feedback on the structure and composition of assembled objects. Here we report a sensitive assay for the quality of assembly. The method relies on measuring the content of unpaired DNA bases in self-assembled DNA objects using a fluorescent de-Bruijn probe for three-base ‘codons’, which enables a comparison with the designed content of unpaired DNA. We use the assay to measure the quality of assembly of several multilayer DNA origami objects and illustrate the use of the assay for the rational refinement of assembly protocols. Our data suggests that large and complex objects like multilayer DNA origami can be made with high strand integration quality up to 99%. Beyond DNA nanotechnology, we speculate that the ability to discriminate unpaired from paired nucleic acids in the same macromolecule may also be useful for analysing cellular nucleic acids.

AbstractTo overcome the limitations and misjudgments of conventional prediction of arrhythmic cardiotoxicity, we have developed an on-chipin vitropredictive cardiotoxicity assay using cardiomyocytes derived from human stem cells employing a constructive spatiotemporal two step measurement of fluctuation (short-term variability; STV) of cell's repolarization and cell-to-cell conduction time, representing two origins of lethal arrhythmia. Temporal STV of field potential duration (FPD) showed a potential to predict the risks of lethal arrhythmia originated from repolarization dispersion for false negative compounds, which was not correctly predicted by conventional measurements using animal cells, even for non-QT prolonging clinical positive compounds. Spatial STV of conduction time delay also unveiled the proarrhythmic risk of asynchronous propagation in cell networks, whose risk cannot be correctly predicted by single-cell-based measurements, indicating the importance of the spatiotemporal fluctuation viewpoint ofin vitrocell networks for precise prediction of lethal arrhythmia reaching clinical assessment such as thorough QT assay.
A high-performance thioredoxin-based scaffold for peptide immunogen construction: proof-of-concept testing with a human papillomavirus epitope

Published: April 2014

AbstractEscherichia coli thioredoxin has been previously exploited as a scaffold for the presentation/stabilization of peptide aptamers as well as to confer immunogenicity to peptide epitopes. Here we focused on other key features of thioredoxin that are of general interest for the production of safer and more effective peptide immunogens, such as a high thermal stability, lack of cross-reactivity and a low-cost of production. We identified thioredoxin from the archaebacterium Pyrococcus furiosus (PfTrx) as a novel scaffold meeting all the above criteria. PfTrx is a highly thermostable and protease-resistant scaffold with a strong (poly)peptide solubilisation capacity. Anti-PfTrx antibodies did not cross-react with mouse, nor human thioredoxin. Untagged PfTrx bearing a previously identified HPV16-L2 peptide epitope was obtained in a >90% pure form with a one-step thermal purification procedure and effectively elicited the production of neutralizing anti-HPV antibodies. We thus propose PfTrx as a superior, general-purpose scaffold for the construction of safe, stable and low-cost peptide immunogens.
