Lifshitz localization‐based reconfigurable photonic crystals
Authors: De Los Santos Héctor J. , Kang Seok‐Won , Banerjee Debjyoti 
Published: September 2011

AbstractWe theoretically investigate programming the functionality of photonic crystals (PCs) by reconfiguring the random location of defects. It is shown, via numerical finite‐difference time‐domain simulations, that the random spatial location of defects, implemented as identical changes in refractive index with respect to the host lattice, has the potential to enable realizing a large number of functions, from optical switching, based on the transition from localized to extended light wave propagation states, to beam steering, and slow light functions. The reconfigurability concept exploits nanofluidic capillarity in nanochannels to change the refractive index properties of individually addressable fluidic‐based defects. © 2011 Wiley Periodicals, Inc.

Published: September 2011

AbstractA 51‐year‐old woman underwent total laparoscopic hysterectomy for complex hyperplasia; however, final postoperative pathology revealed a deeply invasive high‐grade adenocarcinoma. The patient was, therefore, unstaged. Forty‐five days later, she underwent robot‐assisted radical parametrectomy, upper vaginectomy, and bilateral salpingo‐oophorectomy with pelvic and para‐aortic lymph node dissection.
Shelfbreak upwelling induced by alongshore currents: analytical and numerical results
Authors: Miller Robert N. , Matano Ricardo P. , Palma Elbio D. 
Published: September 2011

AbstractAlongshore flow in the direction of propagation of coastal trapped waves can result in upwelling at the shelfbreak. The intensity of this upwelling can be comparable in magnitude to wind-driven coastal upwelling, with its associated ecological features. Recent numerical experiments by Matano & Palma indicate that this upwelling results from convergence of Ekman transport at the shelfbreak. The mechanism for this phenomenon can be understood in terms of steady solutions to the shallow water equations in the presence of Coriolis force and bottom drag. Matano & Palma interpreted their numerical results in terms of the arrested topographic wave, but did not present direct comparisons. Here we present a family of analytical solutions to the equations of the arrested topographic wave that shows striking quantitative agreement with earlier numerical results.
On the propagation of non-isothermal gravity currents in an inclined porous layer
Authors: Rayward-Smith W. J. , Woods Andrew W. 
Published: September 2011

AbstractWe consider the buoyancy-driven flow in an inclined porous layer which results when fluid of different temperature and composition to that in the reservoir is injected from a horizontal line well. The thermal inertia of the porous matrix leads to a transition in the temperature of the injectate as it spreads from the well and heats up to reservoir temperature. Since the buoyancy and viscosity of the injectate change across this thermal transition, the alongslope characteristic speed of the current also changes. Density and viscosity typically decrease with temperature and, so, for injectate that is positively buoyant at reservoir temperature, the changes in density and viscosity with temperature have complementary effects on the characteristic speed. In contrast, for injectate that is negatively buoyant at reservoir temperature, the changes in viscosity and density with temperature have competing influences on the characteristic speed. The change in characteristic speed, combined with the change in buoyancy across the thermal transition, leads to a series of different flow morphologies with the thermally adjusted injectate either running ahead of or lagging behind the original injectate. By approximating the thermal transition as a discrete jump, we derive the leading-order structure of these currents for the different possible cases. We then build on this to develop a more detailed boundary layer description of the thermal transition based on the theory of thin gravity driven flows in porous media. Under certain injection conditions, we show that the thermal transition is gravitationally unstable and that this may lead to mixing across the thermal transition. We consider the implications of the models for several industrial processes including geothermal heat recovery, aquifer thermal storage and carbon dioxide sequestration.
Determination of prey capture rates in the stony coralGalaxea fascicularis: a critical reconsideration of the clearance rate concept

Published: September 2011

In order to determine optimal feeding regimes for captive corals, prey capture by the scleractinian coralGalaxea fasciculariswas determined by measuring clearance of prey items from the surrounding water. Colonies ofG. fascicularis(sized between 200 and 400 polyps) were incubated in 1300 ml incubation chambers. Nauplii of the brine shrimpArtemiasp. were used as the prey item. A series of incubation experiments was conducted to determine the maximal capture per feeding event and per day. To determine maximal capture per feeding event, total uptake of nauplii after one hour was determined for different prey item availabilities ranging from 50 to 4000 nauplii per polyp. To determine maximal capture per day, the corals were subjected to four repetitive feeding events at three different prey item densities (50, 100 and 150 nauplii per polyp). Alongside these quantitative experiments, it was tested to what extent the feeding response of corals is triggered by chemical cues. One hour after food addition, extract ofArtemianauplii was added to the incubation chambers to test its effect on subsequent prey capture rates. In all experiments, prey capture was expressed as the number of nauplii consumed per coral polyp. Total capture ofArtemianauplii byG. fascicularisafter a single feeding event increased linearly up till a prey item availability of 2000 nauplii per polyp. Maximal capture per feeding event was estimated at 1200 nauplii per polyp, which is higher than rates reported in previous studies. It became apparent that at high densities ofArtemianauplii, the clearance rate method does not discriminate between active capture and passive sedimentation. Repetitive feeding with 50 nauplii per polyp resulted in a constant total prey capture per feeding event. At a supply of 100 nauplii per polyp, total capture decreased after the first feeding event, and remained constant during the subsequent feeding events at a level comparable to the lower food availability. However, at a supply of 150 nauplii per polyp, total capture per event was higher throughout the entire four-hour incubation period, which obfuscates an accurate estimation of the maximal daily food uptake. In all incubations, a decrease in capture efficiency was observed within the course of the feeding event. In all repetitive feeding experiments, capture efficiency increased immediately upon addition of a new batch of food. This increase in efficiency was not caused by a priming effect of extract ofArtemia. The inconsistencies in the data show that estimates of prey capture based on clearance rates should be interpreted with caution, because this method does not take into account potential dynamics of prey capture and release.

SUMMARYHere we present the detection of a gene cluster forNeospora caninumsurface genes, similar to theToxoplasma gondiiSRS9 locus, and the cloning and characterization of the NcSRS9gene. PCR genome walking, using NcBSR4gene as a framework, allows the identification, upstream NcBSR4, of 2 sequences homologous to theSRS5and the Ubiquinol-cytochrome C reductase genes and, downstream NcBSR4, of an ORF of 1191 bp coding for a 396-amino acid polypeptide with 59% similarity to the TgSRS9 antigen. A putative 39-residue signal peptide was found at the NH2-terminus followed by a hydrophilic region, and a potential site for a glycosylphosphatidylinositol anchor at the COOH-terminus. A recombinant NcSRS9 protein was produced and was recognized on a Western blot by a low proportion of sera from a panel of naturally infected cows and calves. In addition, Western blot analysis using polyclonal anti-rNcSRS9 revealed stage-specific expression of NcSRS9 in bradyzoites but not in tachyzoites, and immunohistochemistry on brain from a congenitally infected calf showed NcSRS9 recognition in bradyzoites contained in tissue cysts. However, bradyzoite-specific expression of NcSRS9 could not be proven by immunofluorescence on bradyzoites obtainedin vitroand RT-PCR analysis showed no significant variations of NcSRS9transcripts duringin vitrotachyzoite-bradyzoite switch, probably due to incomplete maturity ofin vitrobradyzoites. Initial characterization of NcSRS9 in this study may lead to further studies for a better understanding ofN. caninumpersistence.

Published: September 2011

SUMMARYThis study examined whetherAscaridia galliinfection can be controlled by dietary non-starch polysaccharides (NSP) in chickens. One-day-old chicks were fed either a basal diet (CON) or CON plus insoluble NSP (I-NSP), or CON plus soluble NSP (S-NSP) for 11 weeks. Three weeks later, birds from half of each feeding group were inoculated with 250 embryonated eggs ofA. galli, and slaughtered 8 weeks post-infection to determine worm counts. Both NSP diets, particularly S-NSP, increased prevalence of infection (P<0·05) and worm burden (roughly +50%) of the birds (P<0·001).A. galliinfection caused a less efficient (P=0·013) feed utilization for body weight gain (BWG) resulting in lower body weights (P<0·001) irrespective of type of diet consumed. NSP-fed birds, particularly those on I-NSP, consumed more (+8%) feed per unit BWG and showed retarded (P<0·001) BW development compared to CON-fed birds. Intracaecal pH was lowered by S-NSP (P<0·05). Both NSP diets increased the volatile fatty acids pool size in caeca (P<0·001) with S-NSP exerting a greater effect (+46%) than I-NSP (+24%). It is concluded that both NSPs supplemented diets alter gastrointestinal environment in favour of the nematode establishment, and thus have no potential for controllingA. galliinfection in chickens.
A functional account of verb use in the early stages of English multiword development
Authors: CAMERON-FAULKNER THEA 
Published: September 2011

ABSTRACTThe present study investigates flexibility of verb use in the early stages of English multiword development, and its relationship with patterns attested in the input. The data is taken from a case study of a monolingual English-speaking boy aged 2 ; 5–2 ; 9 and his mother while engaged in daily activities in the home. Data were coded according to Halliday's (1975) functional system. The findings suggest that early multiword verb use is functionally restricted and closely tied to verb use in the input.
Influence of the Antarctic Oscillation, the Pacific–South American modes and the El Niño–Southern Oscillation on the Antarctic surface temperature and pressure variations

AbstractIn this study, the impacts of the Antarctic Oscillation (AAO), the Pacific–South American teleconnection (PSA) and the El Niño–Southern Oscillation (ENSO) on Antarctic sea level pressure and surface temperature are investigated using surface observational data, European Centre for Medium-Range Weather Forecasts (ECMWF) 40 Year Re-analysis (ERA-40) and the National Centers for Environmental Prediction-National Center for Atmospheric Research (NCEP-NCAR) re-analysis data from 1958–2001. There is the most significant correlation between PSA and Antarctic sea level pressure and surface temperature in the northern Antarctic Peninsula during four seasons. But the correlation between Southern Oscillation Index and surface temperature and sea level pressure is significant at some stations only in spring. The three indices can explain a large portion of the trends found in sea level pressure and temperature at some stations, but not at all stations. Among the three indices the most important contribution to the trends in the two surface variables comes from AAO, followed by PSA, and finally by ENSO. The two re-analysis datasets show great similarity for the trends in surface temperature and sea level pressure in April–May and October–November, but not December–February. In summer the trends in surface temperature and sea level pressure in East Antarctica for ERA-40 re-analysis are opposite to those of NCEP re-analysis.
Blue ice areas and their topographical properties in the Lambert glacier, Amery Iceshelf system using Landsat ETM+, ICESat laser altimetry and ASTER GDEM data

AbstractBlue ice extent and its geographical distribution during the three years from December 1999–January 2003 have been mapped together with rock exposure areas for the entire Lambert-Amery glacial basin at an unprecedented level of spatial detail using Landsat ETM+ images. Various geometric and shape attributes for each blue ice patch have been derived. The total area of blue ice is estimated to be 20 422 km2, accounting for 1.48% of the glacial basin. We also found that the image texture information is helpful for distinguishing different types of blue ice: rough blue ice, smooth blue ice, and level blue ice. Rough blue ice areas are mostly associated with glacial dynamics and located in relatively low elevation regions, smooth blue ice areas are often related to nunataks and mountains, steep slopes and wind blows, and level blue ice areas are formed by melt-induced lakes in the margin of the ice shelf and melt-induced ponds on the ice shelf in low elevations. The elevation and surface slope properties of different types of blue ice area are characterized through regional topographical analysis with ICESat laser altimetry data. The effect of mountain height on the blue ice extent is also examined with local topographic profile analysis based on the ASTER global digital elevation model. The wide variation of the ratio of blue ice area length to mountain height indicates that the factors controlling the formation and extent of blue ice are more complicated than we previously thought.
Salazar, the Portuguese Army and Great War Commemoration, 1936–45
Authors: DE MENESES FILIPE RIBEIRO 
Published: September 2011

AbstractAntónio de Oliveira Salazar, dictatorial premier of Portugal from 1932 to 1968, like most conservatives of his generation, had opposed Portugal's intervention in the Great War. Once in power, and especially during his time as Minister of War (1936–44), Salazar attempted to wind down the commemoration ceremonies, which centred on 9 April. His failure to do so is very revealing of the difficult relationship between Salazar and the Portuguese army, which was the main beneficiary of these ceremonies, and which saw itself as having a privileged role within Salazar's New State.
National Identities for Export: East European Cultural Diplomacy in Inter-War Pittsburgh
Authors: NAGY ZSOLT 
Published: September 2011

AbstractThis article examines inter-war east-central European cultural diplomacy as played out in one apparently remote locale: the Nationality Rooms of the Cathedral of Learning at the University of Pittsburgh. Here, a local project originally intended to pay homage to the various immigrants of the Steel City was transformed into a transatlantic project in which the Czechoslovak, Hungarian and Romanian governments (among others) each aimed to construct and propagate a national image abroad. A close looks at this particular ‘transnational construction site’ reveals a surprisingly complex entanglement of cultural production, the construction of national identities, and foreign policy. Battles over space and artistic content also lay bare the sense of competition, urgency and anxiety that, this article argues, characterised inter-war cultural diplomacy in east-central Europe.

Published: September 2011

AbstractAn outbreak of urinary stones associated with consumption of melamine‐tainted milk products occurred in 2008 in China, leading to serious illness of many infants and even death. However, the toxicity of melamine in kidney epithelial cells remains unclear. We have explored the effects of melamine and trolox on renal NRK‐52e (normal rat kidney 52e) cells. The IC50 of melamine was measured by MTT [3‐(4,5‐dimethylthiazol‐2‐yl)‐2,5‐diphenyl‐2H‐tetrazolium bromide] assay. Total SOD (superoxide dismutase) was determined by NBT (Nitro Blue Tetrazolium) staining method. GSH‐Px (glutathione peroxidase) activity was detected by UV colorimetric assay, and MDA (malondialdehyde) content was determined by thiobarbituric acid assay. Apoptosis induced by melamine was determined by flow cytometry. The IC50 increased when NRK‐52e cells were treated with both melamine and trolox compared with melamine only. SOD and GSH‐Px activities were decreased, but MDA content was increased by melamine in a dose‐dependent manner. Trolox significantly enhanced SOD and GSH‐Px activity in melamine‐treated NRK‐52e cells, but it decreased their MDA content. LDH (lactate dehydrogenase) activity and the level of ROS (reactive oxygen species) of the NRK‐52e cells were enhanced by melamine compared with the control. Furthermore, the apoptosis rate increased in NRK‐52e cells treated with melamine, whereas trolox was protective. These results show that melamine has an obvious adverse effect on proliferation of NRK‐52e cells, causing oxidative damage and apoptosis, thus providing a novel insight into renal cytotoxicology of melamine. Trolox ameliorates the effect on melamine toxicity.
