Upper Gondwana Succession of the Rewa Basin, India: Understanding the Interrelationship of Lithologic and Stratigraphic Variables
Authors: Mukherjee Debarati , Ray Sanghamitra , Chandra Saurav , Pal Shrabani , Bandyopadhyay Saswati 
Published: June 2012

Abstract
The current work attempts to address a century old problem regarding the stratigraphic disposition of the Upper Gondwana succession of the Rewa basin based on geological mapping and litholog preparation along well exposed transects. The proposed Upper Gondwana stratigraphy of the Rewa basin comprises a continuous and thick package of Triassic sediments unconformably overlain by the Jurassic Parsora Formation. The Triassic succession consists of a basal Pali Formation, an intermediate and newly designated Karki Formation and the overlying mud-dominant Tiki Formation. These formations are well defined based on physical attributes such as lithology, textures and sedimentary structures, and are easily distinguishable in the field. Based on stratigraphic correlation and fossil content, a Lower-Middle Triassic age has been assigned for the Pali and Karki formations, while the Tiki Formation is Upper Triassic (Carnian) in age. Preliminary observations based on lithological characteristics, sand body geometry and sand: mud ratios suggest that within a fluvial setting there were considerable changes in environments of deposition through time, especially during Triassic to Jurassic transition.
Geochemical Constraints on the Petrogenesis and Tectonic Environment of Gabbroic Intrusives in the Siang Window of Eastern Himalaya, Northeast India
Authors: Singh A. Krishnakanta 
Published: June 2012

Abstract
Carbonate and calcareous-quartzite of Miri-Buxa Group in the Siang Window of Eastern Himalaya intruded by mafic rocks of gabbroic affinity. These intrusive rocks are low-Ti tholeiites (Ti/Y = 379-478; Nb/La = 0.99-1.88) and characterized by enriched LILE-LREE, depleted in HFSE with minor REE fractionation [(La/Yb)N = 2.72-3.35)]. Geochemical behaviour of the incompatible trace elements with the rare earth elements abundances indicates their cogenetic nature and their emplacement in a continental rift tectonic environment. The liquidus olivine temperature of these mafic rocks ranges from 1262°C to 1380°C showing a gentle decrease of [Mg] with a steep increase of [Fe]. These charters thus imply that the rocks are either related to the extent of common source or fractionational crystallization of plagioclase and clinopyroxene from a single batch parental magma. Petrogenetic modeling of [Mg]-[Fe] and REE indicates that these mafic intrusives probably derived from a mantle source similar to komatiitic composition at moderate to high degree (8%-20%) of partial melting.
Guembelitria (Foraminifera) in the Upper Cretaceous-Lower Paleocene Succession of the Langpar Formation, India and its Paleoenvironmental Implication
Authors: Mukhopadhyay Sanjay Kumar 
Published: June 2012

Abstract
Guembelitria is an essential biotic component in the Late Cretaceous-Early Paleogene (K/Pg) marine successions to provide crucial information about the K/Pg boundary; however, it is not well studied in Indian subcontinent. Biostratigraphically well constrained K/Pg successions of Therriaghat and Mahadeo in the East Khasi Hills District, Meghalaya, India provided a scope to present a comprehensive account of the genus in the perspective of differences of opinion about its species. A total of six species including Guembelitria langparensis n. sp., are recognized and their stratigraphic distribution is recorded. A review of the taxonomic validity of the known species, an evaluation of the diverse concepts of Guembelitria cretacea Cushman, and semiquantitative analysis of the recovered species permitted their clustering into two morphogroups that had different ecology. Morphogroup I comprising Guembelitria cretacea, Guembelitria trifolia and Guembelitria langparensis n. sp., is characterized by flared and short spire tests that form a bioseries and thrived as surface floaters. Morphogroup II comprising Guembelitria irregularis, Guembelitria danica and Guembelitria sp a, possesses high spire, narrow tests that have morphological abnormalities and had preference for living in subsurface stressed environment. The occurrence of the species and accompanying other features like ratio of planktonic to benthic foraminifera (p/b), lithologic assemblage and incidence of phosphorite, are used to infer depositional environments and sea level changes during successive biozones of the sequence. The recognized Guembelitria events during the K/Pg transition are discussed with reference to world occurrences.
Artificial Neural Network or Empirical Criteria? A Comparative Approach in Evaluating Maximum Charge per Delay in Surface Mining - Sungun Copper Mine

Published: June 2012

Abstract
Ground vibration due to blasting causes damages in the existence of the surface structures nearby the mine. The study of vibration control plays an important role in minimizing environmental effects of blasting in mines. Ground vibration regulations primarily rely on the peak particle velocity (PPV, mm/s). Prediction of maximum charge weight per delay (Q, kg) by distance from blasting face up to vibration monitoring point as well as allowable PPV was proposed in order to perform under control blasting and therefore avoiding damages on structures nearby the mine. Various empirical predictor equations have proposed to determine the PPV and maximum charge per delay. Maximum charge per delay is calculated by using PPV predictors indirectly or Q predictor directly. This paper presents the results of ground vibration measurement induced by bench blasting in Sungun copper mine in Iran. The scope of this study is to evaluate the capability of two different methods in order to predict maximum charge per delay. A comparison between two ways of investigations including empirical equations and artificial neural network (ANN) are presented. It has been shown that the applicability of ANN method is more promising than any under study empirical equations.
Evaluation of desktop operating systems under thrashing conditions

Published: June 2012

Abstract
Virtual memory mechanisms allow offering more RAM memory space to processes than the amount of memory physically available in the system, using disk space as a memory extension. When there is not enough RAM memory to satisfy the active processes’ working sets, the system throughput may be significantly reduced, due to the excessive paging activity. Such situation is known as memory thrashing. This paper presents an evaluation of some commodity desktop operating systems under thrashing conditions. We also identify and discuss the performance data about memory management available in each system and the mechanisms available to collect it. A portable benchmark tool was developed to bring each system to a thrashing situation and then pull it back to normality. The results observed from the systems under study are compared and discussed.

Abstract
Agricultural practices affect the physical and chemical characteristics of the soil, which in turn may influence soil microorganisms with consequences on soil biological functioning. However, there is little knowledge on the interactions between agricultural management, soil physicochemical properties, and soil microbial communities, notably in tropical ecosystems with few studies conducted in strongly weathered and acid soils. Here, we investigated the early effect of tillage and crop residues management on top soil physical, chemical, and microbial properties in an acid savannah grassland of northeastern Laos. We initiated a 3-year rotation of rice/corn/soybean under three no-till systems (NTs) distinguished by the cover crops associated prior to and with the main crops, and one conventional tillage-based system (CT). The effect of agricultural management was evaluated 2 years after land reclamation in reference to the surrounding natural pasture (PAS). Our results demonstrate that NTs improve soil physicochemical characteristics (aggregate stability, organic carbon, and cation exchange capacity) as well as microbial abundance (total biomass, bacterial and fungal densities). A significant discrimination of the genetic structure of soil bacterial community was also observed between NTs, CT, and PAS. Interestingly, bacterial abundance and diversity were differently influenced by soil environment changes: microbial density was affected by the quantity and diversity of crop residues, soil organic carbon, and exchangeable base contents, whereas soil bacterial genetic structure was mainly determined by exchangeable aluminum content, pH, cation exchange capacity, and C/N ratio. Altogether, our study represents one of the most complete environmental evaluations of agricultural practices in tropical agrosystems and leads to recommend no-till systems with high residue restitutions to improve the physical, chemical, and microbial properties of tropical acid soils and thus contribute to the sustainability of agriculture in these ecosystems.

AbstractObjectiveTo determine knowledge and beliefs related to human papillomavirus (HPV), cervical cancer, and vaccination among young Thai women, and thereby identify independent predictors associated with acceptance of HPV vaccination.MethodsA convenience sample of 747 young women aged 18–24 years was recruited from universities and colleges located in the upper northern region of Thailand. An online questionnaire was performed to assess demographics; HPV and cervical cancer‐related health characteristics; and knowledge and beliefs toward HPV and cervical cancer. Logistic regression analysis was used to determine independent predictors of HPV vaccine acceptance.ResultsKnowledge about HPV and cervical cancer was moderate. The mean total knowledge score was 7.5 ± 3.8. Acceptance of the HPV vaccine was significantly associated with having received a recommendation for vaccination (odds ratio [OR] 2.12; 95% CI, 1.22–3.68); perceived susceptibility to disease (OR 1.37; 95% CI, 1.22–1.52); perceived benefits of vaccination (OR 1.33; 95% CI, 1.19–1.49); and perceived seriousness of disease (OR 0.90; 95% CI, 0.81–1.00).ConclusionUnderstanding variables associated with acceptance of HPV vaccination may guide immunization initiatives and so increase the uptake rate among young Thai women.

AbstractObjectiveTo establish knowledge and practice of contraception among patients presenting with a fistula attending fistula care services at 4 centers in Kenya.MethodsIn a descriptive cohort study carried out between January and December 2011, patients presenting with a history of urine and/or stool leakage were screened and those with confirmed diagnosis of fistula were assessed and prepared for surgery. Informed consent was obtained from study participants before surgical intervention. After surgery, a standard questionnaire was used to collect information on sociodemographics, duration of leakage, and reproductive health practices.ResultsA total of 206 patients were interviewed. Most of the patients were young (mean age 22 years). Literacy was low: only 1.7% reported tertiary‐level education, and 56.7% reported primary‐level education. With regard to family planning, 76.2% of patients expressed a willingness to use contraception after fistula repair.ConclusionAmong patients presenting with a fistula in Kenya, the unmet need for family planning was high. There is an urgent need for healthcare providers to integrate family planning services in fistula care programs.
The effect of management team characteristics on risk‐taking and style extremity of mutual fund portfolios
Authors: Karagiannidis Iordanis 
Published: June 2012

AbstractThis paper investigates the effect of management team‐level characteristics on portfolio risk and style extremity using a unique dataset of 1678 mutual fund managers. Results show that teams with more members, longer tenure, and more members with graduate business training hold less risky portfolios. The opposite is true for teams whose members engage in side‐by‐side management; that is, they manage multiple funds simultaneously. Member diversity is related to less extreme style decisions. These findings have important implications for fund management companies as they make decisions about the composition of management teams as well as for individual investors’ investment allocation decisions.
Pathophysiology of BRONJ: Drug‐related osteoclastic disease of the jaw
Authors: Ikebe Tetsuro 
Published: June 2012

AbstractSince the first article about bisphosphonate‐related osteonecrosis of the jaw (BRONJ) was published in 2003, clinical and basic research for BRONJ has continued worldwide to understand this novel disease. Several organizations have proposed the definition, diagnostic criteria, risk factors, and treatment strategy for BRONJ. Recently, some new drugs used for cancer patients such as bevacizumab and sunitinib have also been reported to be involved in osteonecrosis of the jaw (ONJ). Because ONJ appears to be initially derived from osteoclast inhibition, a new category of diseases named as “drug‐related osteoclastic disease of the jaw” may be assumed. Considering the accumulated knowledge related to BRONJ, including osteoclast biology, bisphosphonate pharmacology, animal experiments, and clinicopathological findings, a perspective of BRONJ from the pathophysiological viewpoint is proposed in this review.
SAVE OUR COWS? AUGUSTAN DISCOURSE AND ANIMAL SACRIFICE IN OVID’S FASTI
Authors: GREEN STEVEN J. 
Published: June 2012

The interaction between Roman religion and Ovid’s ostensibly religious poem, Fasti, has only begun to be appreciated in the past twenty years or so. Before this time, scholars were typically either uncritical of Ovid’s poem – taking it at face value as a quarry from which to mine reliable gems of information on Roman religion – or far too critical, chastizing the poet for what they saw as errors from a man ignorant of his own national religion. From the mid 1980s, however, there has emerged a better understanding of the complex nature of Roman religion. Scholars now stress the fundamental role of exegesis (multiple interpretation) in a religion which has no underlying orthodoxy. As such, it is argued that Roman religion was not something concrete, tangible, and external, to which literature related faithfully or otherwise, but that literature had a central role in articulating the dynamics of the religious experience of the Romans.One can now duly expect and appreciate, therefore, a variety of contrasting views on Roman religious activity presented in Fasti, without resorting to arguments about Ovidian ignorance or the apparently incomplete state of the poem itself.
CEYX AND ALCYONE: OVID, METAMORPHOSES 11, 410–748
Authors: RUDD NIALL 
Published: June 2012

Prelude (290–409): Ceyx, king of Trachis, just west of the Malian Gulf, was the son of Lucifer, the morning star, and he bore witness to his birth by the radiance of his face (271–2). He was a man of peace, unlike his brother, Daedalion, a fierce soldier, who, in a frenzy of grief at the murder of his daughter by Diana was pitied by Apollo and turned into a hawk (339–45). This was followed by another weird episode – the appearance of a monstrous wolf, which, after causing widespread destruction, was turned into a stone by Thetis (365–406). A (410–73): Worried by these strange events, Ceyx decides he must consult the oracle of Apollo. He cannot, however, go to Delphi, which is not far south, because it is being blockaded by Phorbas and the Phlegyans. So he prepares to go to Claros on the coast of Asia Minor. As the ship moves out to sea, Ceyx stands on the poop waving to his wife (A 465).Alcyone waves back, even though she is prostrate on the ground – collapsaque corpore toto est (460).Ovid gives a beautiful description of how first Ceyx himself ceases to be visible, then the hull moves out of sight and only the sails on the yard-arm can still be seen; finally, they, too, disappear over the horizon (A 466–71).
Regional biases in absolute sea‐level estimates from tide gauge data due to residual unmodeled vertical land movement

Published: June 2012

The only vertical land movement signal routinely corrected for when estimating absolute sea‐level change from tide gauge data is that due to glacial isostatic adjustment (GIA). We compare modeled GIA uplift (ICE‐5G + VM2) with vertical land movement at ∼300 GPS stations located near to a global set of tide gauges, and find regionally coherent differences of commonly ±0.5–2 mm/yr. Reference frame differences and signal due to present‐day mass trends cannot reconcile these differences. We examine sensitivity to the GIA Earth model by fitting to a subset of the GPS velocities and find substantial regional sensitivity, but no single Earth model is able to reduce the disagreement in all regions. We suggest errors in ice history and neglected lateral Earth structure dominate model‐data differences, and urge caution in the use of modeled GIA uplift alone when interpreting regional‐ and global‐ scale absolute (geocentric) sea level from tide gauge data.

AbstractRegenerative therapy based on stem cells is applied as standard therapy in pediatric oncology. Furthermore, they are frequently used to treat immunodeficiency disorders of infants. For severe neonatal diseases, e. g. hypoxic-ischemic encephalopathy in term neonates or bronchopulmonary dysplasia in preterm infants, animal models have been established. According to some first preclinical results stem cell administration appears as a promising tool to improve the clinical outcome in high-risk infants. Provided the benefit of regenerative therapies can further be evaluated in appropriate preclinical neonate models, carefully controlled clinical trials to assess the significance of regenerative therapies, such as autologous stem cell administration, are indicated.

G protein-coupled receptors (GPCRs) are major drug targets, and their ligands are currently being explored and developed by many pharmaceutical companies and independent researchers. Class A (rhodopsin-like) GPCRs compose a predominant GPCR family; therefore, class A GPCR ligands are in demand. Growth hormone secretagogue receptor (GHS-R) is a class A GPCR that stimulates food intake by binding to its peptide ligand, ghrelin. Therefore, antagonists of GHS-R are expected to exert antiobesity function. In this article, we describe the use of cDNA display to screen for successfully and identify an antagonistic peptide of GHS-R. The antagonistic peptide inhibited the ghrelin-induced increase in intracellular Ca
2+
in vitro (IC

= approximately 10 μM) and repressed the contraction of isolated animal stomach in response to ghrelin. Furthermore, peripheral administration of the peptide inhibited the food intake of mice. This work provides new insight into the development of antiobesity drugs and describes a method for the discovery of unique peptide ligands for class A GPCRs.

Published: June 2012

AbstractAtlantic salmon Salmo salar of U.S. hatchery origin were captured as postsmolts by surface trawling during spatial surveys in late May to mid‐June in the northeastern Gulf of Maine in 2002 and 2003. Most marked and unmarked postsmolts were from the Penobscot River, but some were also from the Dennys and other rivers of the Gulf of Maine. The capture rate of stocked smolts was very low (≤0.01%), and it was highest for marked smolts from known rivers and proportional to numbers stocked. Marked postsmolts were caught 16–43 d after their release as smolts and 89–240 km from their river of origin. The rate of migration from different rivers differed and varied annually, and it accounted for some of the observed differences in capture rate. The weight of postsmolts from known rivers was greater than at smolt stocking and river exit, indicating early marine growth. The distribution of U.S. postsmolts from different rivers was similar, and they were often caught together, as were those from the same river. As a result of this close association during migration, postsmolt catches were aggregated at a few adjacent locations in several areas of the Gulf of Maine. Postsmolts crossing the Gulf of Maine were found east of Jordan Basin and most were along a corridor near shore at the eastern edge of the area surveyed along the southwest coast of Nova Scotia, Canada. Postsmolts of U.S. origin were found in areas used by other salmon populations also leaving the Bay of Fundy during May and June. This seasonal occurrence in a specific coastal area provides an opportunity to manage activities within that corridor to mitigate potential losses of Atlantic salmon from endangered and threatened populations in North America.
