Characteristics of light and dark alternations in Owen Ridge sediments (Appendix)

Clay mineral relative abundances in approximately 450 samples from cores recovered during ODP Leg 117 in the Arabian Sea have been used to examine the paleoclimatic, paleoenvironmental, and tectonic histories of the Indus Fan, Owen Ridge, Oman margin, and adjacent continental source regions. Geographic variations in the relative abundances of minerals and correlations with depositional processes support previous interpretations that smectite has been supplied from weathering of the Deccan Traps; illite and chlorite have been supplied either from the Himalayas via marine transport or from the Iran-Makran region by winds; and palygorskite has been supplied from the Arabian peninsula and Somalia by winds. Pleistocene sediments of the Indus Fan record two modes of deposition: turbidites supplied from the Indus drainage and dominated by illite and chlorite, and pelagic carbonates containing smectites and wind-transported palygorskite. Local and regional causes for shifts between these depositional processes cannot be demonstrated conclusively with the data available, but sea-level fluctuations probably exerted a significant control on the rate of turbidite influx. Lower Miocene sediments on the Owen Ridge are also turbidites supplied by the Indus drainage; in the middle Miocene, a shift to pelagic carbonates records the uplift of the Owen Ridge, and is accompanied by the increased relative importance of wind-transported palygorskite. Associations of palygorskite and biosiliceous components in middle to upper Miocene sediments are interpreted to record vigorous monsoonal circulation and accompanying upwelling-produced biological productivity. Mineralogic and geochemical data indicate that light/dark color alternations in upper Miocene sediments on the Owen Ridge record climatic fluctuations, but the climatic significance of similar alternations in Pliocene-Pleistocene sediments is unclear. Palygorskite is the dominant clay on the Oman margin, reflecting proximity to its source areas. On the Oman margin, clay mineral relative abundances are most variable at structurally complex sites, indicating that local depositional settings have been influenced by their tectonic histories since the Miocene.

Service difficulties - Will UCPR r 117 provide the answer?

In Amci Pty Ltd ACN 124 249 485 v Corcoal Management Pty Ltd [2013] QSC 50 Jackson J considered an application for an order under r117 of the Uniform Civil Procedure Rules 1999 (Qld) (UCPR) in relation to informal service of an originating process on a corporation registered in the Ajman Free Zone in the United Arab Emirates. The decision appears to be the first time a Queensland court has examined the scope of r117 of the UCPR, and relevant considerations influencing the exercise of the discretion under the rule, when the defendant is outside Australia.

Teología, 2015, Tomo LII nº 117 (número completo)

Nota del Director: "La presentación de esta revista Teología coincide con un momento de fiesta grande para nuestra Facultad: la celebración del Congreso del Centenario. De allí que este número quiera expresar la alegría que nos produce encontrarnos a hablar de teología, para recordar nuestras raíces, afrontar las exigencias de los desafíos de nuestro tiempo e imaginar un futuro. La teología es un quehacer creativo: pues es hermenéutica del mundo comprendido desde la fe; porque además es profecía, vinculando el presente con el futuro y haciéndonos responsables de las respuestas para hoy y de los proyectos para el tiempo que se avecina; y también es memoria, reconociendo que ella se hace con una comunidad que nos antecedió, es diálogo con las experiencias pasadas y aprendizaje de quienes hablaron antes que nosotros. En este sentido, pensar debe integrar el tiempo en sus dimensiones. Este número de nuestra revista presenta un grupo de textos que muestran esos diversos registros en los que la teología desarrolla su tarea..."

The predatory feeding of Acanthocyclops viridis (Jur.) (Copepoda, Cyclopoida). [Translation from: Trudy Inst.Biol.Vodokhranil. 2(5) 117-127, 1959. ]

The feeding of freshwater copepods, especially cyclopoida, has been poorly covered in research so far. The majority of existing special works on the feeding of cyclopoida illustrate this question only from the qualitative side. The food content of the nauplius of freshwater cyclops has not been studied at all, as also the feeding of adult entomostracans on bacteria. Moreover the question of the suitability of vegetable food for Cyclops is not clear enough. This article aims to elucidate as fully as possible the nutrition of Acanthocyclops viridis (Jur.) - a large cyclops, inhabiting the mass of demersal layers of the open parts of the Rybinsk reservoir and its foreshore. The present work is devoted only to the predatory feeding of A. viridis, and includes data from the content of the intestines of cyclops, collected in natural conditions, and also the results of experimental observations carried out in a laboratory during 1958.

Investigations on saprolegniosis. II. Study on the process of penetrations showing evidence of a proteolytic enzyme and histopathological aspects [Translation from: Riv.ital.Piscicolt.Ittiopatol. 11(4), 109-117, 1976]

The study of enzymatic activity is of great importance in the immunology of fungi. Indeed, knowledge of biological activity of antigenic structures is important for the elucidation of host-parasite relations as well as in the search for a taxonomic factor permitting differential diagnoses. The authors used Saprolegnia cultures to analyse soluble antigenic fractions arising from the mycelium of cultures of 4 species of Saprolegnia, which are found most frequently in the parasitic state on fish: S. parasitica, S. ferax, S. delica, S. diclina. The authors conclude that in the study of saprolegniasis, the enzymatic approach affords new elements for the examination of the etiology of fungi as well as an element of gravity concerning the biochemical modifications necessary to the change of saprophytism to parasitism.

High- and low-latitude climate interactions: evidence for enhanced aridity of Asian monsoon dust source areas after 2.4 MYR from ODP Leg 117 magnetic susceptibility data

EXTRACT (SEE PDF FOR FULL ABSTRACT): Whole-core magnetic susceptibility can sometimes be used as a rapid and sensitive indicator of variations in the concentration of terrigenous material. We apply this approach to study the evolution of Plio-Pleistocene climatic cycles of terrigenous sedimentation at Ocean Drilling Program Site 721, on the Owen Ridge in the Arabian Sea.

Possible way to synthesize superheavy element Z=117

Within the framework of the dinuclear system model, the production of superheavy element Z = 117 in possible projectile-target combinations is analysed systematically. The calculated results show that the production cross sections are strongly dependent on the reaction systems. Optimal combinations, corresponding excitation energies and evaporation channels are proposed, such as the isotopes Bk-248,Bk-249 in Ca-48 induced reactions in 3n evaporation channels and the reactions Sc-45+Cm-246,Cm-248 in 3n and 4n channels, and the system V-51+Pu-244 in 3n channel.

Relativistic Mean Field Study of the Z=117 Isotopic Chain

The properties of the Z = 117 isotopic chain are studied within the framework of the axially deformed relativistic mean field theory (RMFT) in the blocked BCS approximation. The ground-state properties, such as binging energies, deformations as well as the possible.. decay energies and lifetimes are calculated with the parameter set of NL-Z2 and compared with results from the finite range droplet model. The analysis by RMFT shows that the isotopes in the range of mass number A = 291 similar to 300 exhibit higher stability, which suggests that they may be promising nuclei to be hopefully synthesized in the lab among the nuclei Z = 117.

Li-6 in the atmosphere of GJ 117 revisited

Detection of Li-6 has been shown for energetic solar events, one chromospherically active binary, and several dwarf halo stars. We had previously found a Li-6/Li-7 = 0.03 +/- 0.01 for active K dwarf GJ 117 using VLT UVES observations. Here we present high signal-to-noise (> 1000) high spectral resolution observations taken with the McDonald Observatory's 2.7 m and echelle spectrometer of GJ 117. We have used the solar spectrum and template stars to eliminate possible blends, such as Ti I, in the Li-6 spectral region. Our new analysis, using an updated PHOENIX model atmosphere, finds Li-6/Li-7 = 0.05 +/- 0.02. In addition, bisector analysis showed no significant red asymmetries that would affect the lithium line profile. No changes above the statistical uncertainties are found between the VLT and McDonald data. The amount of Li-6 derived for GJ 117 is consistent with creation in spallation reactions on the stellar surface, but we caution that uncertainties in the continuum level may cause additional uncertainty in the Li-6 fraction.

A puzzling periodicity in the pulsating DA white dwarf G 117-B15A

We present time-resolved optical spectrophotometry of the pulsating hydrogen atmosphere (DA) white dwarf G 117-B15A. We find three periodicities in the pulsation spectrum (215 s, 272 s, and 304 s) all of which have been found in earlier studies. By comparing the fractional wavelength dependence of the pulsation amplitudes ( chromatic amplitudes) with models, we confirm a previous report that the strongest mode, at 215 s, has l = 1. The chromatic amplitude for the 272 s mode is very puzzling, showing an increase in fractional amplitude with wavelength that cannot be reproduced by the models for any ` at optical wavelengths. Based on archival HST data, we show that while the behaviour of the 215 s mode at ultra-violet wavelengths is as expected from models, the weird behaviour of the 272 s periodicity is not restricted to optical wavelengths in that it fails to show the expected increase in fractional amplitude towards shorter wavelengths. We discuss possible causes for the discrepancies found for the 272 s variation, but find that all are lacking, and conclude that the nature of this periodicity remains unclear.

Menarche, menopause, and breast cancer risk: individual participant meta-analysis, including 118 964 women with breast cancer from 117 epidemiological studies.

BACKGROUND: Menarche and menopause mark the onset and cessation, respectively, of ovarian activity associated with reproduction, and affect breast cancer risk. Our aim was to assess the strengths of their effects and determine whether they depend on characteristics of the tumours or the affected women. METHODS: Individual data from 117 epidemiological studies, including 118 964 women with invasive breast cancer and 306 091 without the disease, none of whom had used menopausal hormone therapy, were included in the analyses. We calculated adjusted relative risks (RRs) associated with menarche and menopause for breast cancer overall, and by tumour histology and by oestrogen receptor expression. FINDINGS: Breast cancer risk increased by a factor of 1·050 (95% CI 1·044-1·057; p<0·0001) for every year younger at menarche, and independently by a smaller amount (1·029, 1·025-1·032; p<0·0001), for every year older at menopause. Premenopausal women had a greater risk of breast cancer than postmenopausal women of an identical age (RR at age 45-54 years 1·43, 1·33-1·52, p<0·001). All three of these associations were attenuated by increasing adiposity among postmenopausal women, but did not vary materially by women's year of birth, ethnic origin, childbearing history, smoking, alcohol consumption, or hormonal contraceptive use. All three associations were stronger for lobular than for ductal tumours (p<0·006 for each comparison). The effect of menopause in women of an identical age and trends by age at menopause were stronger for oestrogen receptor-positive disease than for oestrogen receptor-negative disease (p<0·01 for both comparisons). INTERPRETATION: The effects of menarche and menopause on breast cancer risk might not be acting merely by lengthening women's total number of reproductive years. Endogenous ovarian hormones are more relevant for oestrogen receptor-positive disease than for oestrogen receptor-negative disease and for lobular than for ductal tumours. FUNDING: Cancer Research UK.
