"Historical black carbon deposition in the Canadian High Arctic: a <i>></i>250-year long ice-core record from Devon Island."

Abstract. Black carbon aerosol (BC), which is emitted from natural and anthropogenic sources (e.g., wildfires, coal burning), can contribute to magnify climate warming at high latitudes by darkening snow- and ice-covered surfaces, and subsequently lowering their albedo. Therefore, modeling the atmospheric transport and deposition of BC to the Arctic is important, and historical archives of BC accumulation in polar ice can help to validate such modeling efforts. Here we present a > 250-year ice-core record of refractory BC (rBC) deposition on Devon ice cap, Canada, spanning the years from 1735 to 1992. This is the first such record ever developed from the Canadian Arctic. The estimated mean deposition flux of rBC on Devon ice cap for 1963–1990 is 0.2 mg m−2 a−1, which is at the low end of estimates from Greenland ice cores obtained using the same analytical method ( ∼ 0.1–4 mg m−2 a−1). The Devon ice cap rBC record also differs from the Greenland records in that it shows only a modest increase in rBC deposition during the 20th century. In the Greenland records a pronounced rise in rBC is observed from the 1880s to the 1910s, which is largely attributed to midlatitude coal burning emissions. The deposition of contaminants such as sulfate and lead increased on Devon ice cap in the 20th century but no concomitant rise in rBC is recorded in the ice. Part of the difference with Greenland could be due to local factors such as melt–freeze cycles on Devon ice cap that may limit the detection sensitivity of rBC analyses in melt-impacted core samples, and wind scouring of winter snow at the coring site. Air back-trajectory analyses also suggest that Devon ice cap receives BC from more distant North American and Eurasian sources than Greenland, and aerosol mixing and removal during long-range transport over the Arctic Ocean likely masks some of the specific BC source–receptor relationships. Findings from this study suggest that there could be a large variability in BC aerosol deposition across the Arctic region arising from different transport patterns. This variability needs to be accounted for when estimating the large-scale albedo lowering effect of BC deposition on Arctic snow/ice.

Full textAbstract:
A new Devonian fossil fish fauna from the region of Caño Colorado between the Rio Palmar and Rio Socuy, Sierra de Perijá, Venezuela, comes from two localities and several horizons within the Campo Chico Formation, dated on plants and spores as Givetian-Frasnian in age. Placoderms are most common, with the antiarch <i>Bothriolepis perija</i> n. sp., showing affinity with species from the Aztec fish fauna of Victoria Land, Antarctica. A second antiarch, <i>Venezuelepis mingui</i> n.g. n.sp., is also closely related to an Antarctic species, which is reassigned to this new genus. Fragmentary remains of a phyllolepid placoderm show similarity to the genus <i>Austrophyllolepis</i> from southeastern Australia. Chondrichthyan spines are provisionally referred to the Antarctilamnidae, and acanthodian remains include spines of the widespread taxon <i>Machaeracanthus</i>. Osteichthyans are represented by osteolepid and dipnoan scales and teeth, and scales lacking cosmine which may belong to another major taxon. This fauna has provided the first Devonian record from South America of three major fish groups: antiarch and phyllolepid placoderms, and dipnoans. These are widely distributed on most other continents. Although invertebrates and plants from the same sequence closely resemble those of eastern North America, the endemic elements in the fish fauna indicate Gondwana affinities. Phyllolepid placoderms are common in Givetian-Frasnian strata of Australia and Antarctica, but are only known from the Famennian in the Northern Hemisphere. The new phyllolepid occurrence extends their range across the northern margin of Palaeozoic Gondwana. The age and affinities of this new fish fauna are consistent with a model of biotic dispersal between Gondwana and Euramerica at or near the Frasnian-Famennian boundary. A narrow marine barrier separating northern and southern continental landmasses is indicated, in contrast to the wide equatorial ocean for the Late Devonian postulated from palaeomagnetic data. <br><br> Es wird eine neue devonische Fischfauna aus dem Gebiet zwischen Caño Colorado und Rio Socuy, Sierra de Perijá, beschrieben. Die Funde stammen aus zwei Lokalitäten und mehreren Horizonten innerhalb der Campo Chico Formation, die auf Grundlage von Untersuchungen der Pflanzen- und Sporenfunde dem Zeitabschnitt Givetium-Frasnium zugeordnet werden. Placodermen sind durch den Antiarchen <i>Bothriolepis perija</i> n. sp. häufig vertreten. Sie sind mit Arten der Aztec-Fischfauna von Viktoria Land, Antarktis, verwandt. Ein zweiter Antiarche, der <i>Venezuelepis mingui</i> n. g. n. sp. ist eng mit einer Spezies aus der Antarktis verwandt, die ebenfalls dieser neuen Gattung zugeschrieben wird. Fragmentarische Reste eines phyllolepiden Placodermen weisen Ähnlichkeiten mit der Gattung <i>Austrophyllolepis</i> aus dem Südosten Australiens auf. Wirbel eines Chondrichthyer werden vorläufig den Antarctilamnidae zugeschrieben. Acanthodir-Reste schließen das weitverbreitete Taxon <i>Machaeracanthus</i> ein. Osteichthyer sind durch Schuppen und Zähne osteolepider Sarcopterygier und Dipnoi vertreten. Andere Schuppen, denen die Cosminschicht fehlt, gehören vermutlich zu einem anderen Haupttaxon. Damit ist durch diese Fauna der erste Nachweis für das Vorkommen der drei Hauptfischgruppen Antiarchi, phyllolepide Placodermi und Dipnoi im Devon Südamerikas erbracht. Sie sind auch auf den meisten anderen Kontinenten weit verbreitet. Obwohl Invertebraten und Pflanzen aus derselben Zeit sehr denen aus dem Osten Nordamerikas ähneln, weisen die endemischen Elemente in der Fischfauna auf eine Affinität zu Gondwana hin. Phyllolepide Placodermen sind im Givetium-Frasnianium Australiens verbreitet, aber erst aus dem Famennium in der Nordhemisphere bekannt. Das Auftreten eines neuen Phyllolepiden weitet den Vorkommensbereich über die nördliche Linie des paläozoischen Gondwanas hinaus aus. Alter und Verwandtschaftsbeziehungen dieser neuen Fischfauna stimmen mit dem Modell der biotischen Verbreitung zwischen Gondwana und Euramerika an bzw. nah an der Frasnium-Famennium-Grenze überein. Es gibt Hinweise für eine die nördlichen und südlichen Landmassen trennende schmale Meerenge. Dies steht im Gegensatz zur Annahme eines weiten äquatorialen Ozeans im späten Devons, die sich auf palaeomagnetische Daten stützt. <br><br> doi:<a href="http://dx.doi.org/10.1002/mmng.20020050111" target="_blank">10.1002/mmng.20020050111</a>

Devon Energy considers its development of a new completions technology called Sealed Wellbore Pressure Monitoring (SWPM) to be one of the shale sector’s biggest breakthroughs in subsurface engineering. The approach to fracturing diagnostics represents a class of next-generation tools designed to make on-the-fly stimulation designs more practical than ever. But the innovation has done something else, too. It has raised old questions within a relatively new sector about the role of intellectual property (IP) protection. When SWPM was introduced to petrotechnicals outside of Devon, some initially questioned how or why the technique needed to be patented at all. The ingenuity behind SWPM could be boiled down to solving a math problem: How much fluid is pumped during the hydraulic fracturing treatment of one well before it travels across a known distance and applies pressure to the unperforated casing of a neighboring shut-in well? The ability to answer this question rapidly and with surety holds great value for any developer of multiwell pads. But, as some wondered, was this simply a formula that could be repeated and used as freely as a decade’s old equation found in a textbook? Was Devon being too protective over its discovery? Or was it simply being prudent? Earlier this year, Devon was granted a US patent for SWPM, the end of a process that began on a well pad in 2017. In the meantime, the company shared rights with other operators for field trials before striking a deal last summer with software developer Well Data Labs to market SWPM to the rest of the unconventional business. The drivers behind Devon’s IP strategy, what it learned while patenting SWPM, and what it hopes others in this space will take away from that experience are shared here by Chad Holeman, corporate counsel at Devon, and Kyle Haustveit, a co-inventor of SWPM and a subsurface engineering manager at Devon. JPT: Can you begin by explaining your philosophy around IP protection and how SWPM reflects that? Chad Holeman (CH): We talk about confidential and proprietary information with some degree of frequency. As an organization, I think that we’re further along on the spectrum of maturation as it relates to understanding what that means and safeguarding that information to the very best of our ability. One key is that you need to be able to differentiate trade secrets, or confidential proprietary information that you want to keep close to the vest, from the inventive concepts that you want to protect and can also commercialize, potentially monetize, or gain some other type of competitive advantage from. Inventive concepts such as SWPM fit that mold. Kyle Haustveit (KH): I think the concept of leaving value on the table is one of the biggest reasons we do this. A lot of operators have made massive investments into the digital revolution and multimillion-dollar investments into diagnostic programs to understand how we are breaking and draining the rock with our stimulations. Through all that have come a lot of new ideas.

Full textAbstract:
There exists an important class of materials, e.g., debris, volcanic lava, sludges, and remoulded sensitive clays, that are known to behave like a Bingham fluid. One of the important properties of a Bingham fluid is the so-called yield stress, and it is usually determined using a coaxial viscometer apparatus. It would be impractical and cumbersome to use this apparatus for many of the materials referred to earlier, and we propose here to examine the use of the slump test. The slump test is used in the concrete industry to evaluate workability and consistency. A statical model is developed to explain the deformation mechanism, and it permits the determination of yield stress. The validity of the statical model is verified using published data on mortar and our own data on Devon silt. The yield stress obtained with the slump test is also compared with the undrained shear strength obtained using the fall cone test. Good agreement is found between the two values. Key words: Bingham fluid, yield stress, slump test, Devon silt.

Decon is short for decontamination (e.g. stripdown and washdown in response to anthrax scares, etc.), but the term “decon” is also a short form for “deconstruction” (literary criticism asserting multiple conflicting interpretations of philosophical, political or social implications rather than an author's intention). The author describes an anthrax ready mailroom exhibit that included mass casualty decontamination showers, which he built in the summer of 2001, based on a patent he filed in April 2000, to deconstruct the coming “war on terrorism” and the suspension of civil liberties and personal privacy that might follow in the wake of bioterror attacks.

ABSTRACT The concept of an ENVIRONMENT GROUP (EG) was introduced into the UK maritime incident response process shortly after the SEA EMPRESS incident. The Groups role is to provide public health and environmental advice to all response units. The NAPOLI incident presented responders with a highly complex matrix of issues concerned with major salvage, oil pollution at sea and onshore, potential for HNS into the sea and subsequent concerns for environment and public health. Two response cells were set up:- a Salvage Control Unit for all salvage activity and a Marine Response Cell to respond to all pollution at sea. Unusually for a UK incident the response to oil and cargo ashore was dealt with by contractors engaged by the insurers. The NAPOLI EG was set up immediately the container vessel was in difficulties, chaired by a UK Environment Agency officer. The Group was immediately tasked with evaluating the likely impact of a series of possible scenarios involving oil and/or cargo loss. The key to successful management of environmental considerations was the communications network set up between the response cells at Portland Coastguard, the operational EG and the specialist scientists and technicians in UK government departments/agencies. Whilst the EG individual members have specific responsibilities associated with their parent bodies regulatory status, the Groups remit is to present one voice to the response cells when consulted on any issue. That process can be challenging when meeting short timelines. Advice taskings were essentially split between immediate environmental consultations e.g use of dispersants in the event of a spill, and discrete “project” risk evaluations and monitoring protocols e.g. modeling of releases of specific cargo and development of risk assessments and worst case scenarios. Project work was typically carried out by people away from the operations centre thus freeing up the operational EG to concentrate on live issues on a day by day basis. The operational EG maintained regular conference calls with UK government specialists to discuss the need for, the modus operandi and the progress and outcomes of environmental monitoring.

Author's note: A few years ago, I read David Johnson's Spectacle and Sacrifice: The Ritual Foundations of Village Life in North China.1 The book immediately caught my attention because it dealt with parts of China that I know well: southern Hebei and eastern Shanxi provinces, where I was conducting research for a new book. Johnson describes festivals that helped bind together communities, and in several cases had information showing that some of them had been revived after the Cultural Revolution.One, particularly, seemed noteworthy: Guyi Village in the south of Hebei Province. This is near the steel-making city of Handan and one of the most polluted parts of China. I had been there several times and was fascinated with the idea that this area could also be home to elaborate, multi-day rituals that seemed otherwise not to exist in North China. According to Johnson's informants, local scholars had visited the village in the 1990s and seen exciting performances of Zhuo Huanggui, or Chasing the Yellow Demon, an exorcistic purging ritual performed at the end of the fifteen-day Chinese New Year's festival. I contacted local officials and academics, who were unsure if the ritual would be performed again. No one, it seemed, had been out to the village in years. So in mid-February 2014, I set off to see if anything was left of these complex performances.2

AbstractThe paper is based on problems found in a large ‘farm animal’ practice in Devon, in which the author is largely committed to the sheep work. There are some 80 000 sheep in the area, and some 1·5 million in the county of Devon which are kept under varying conditions from the high areas of Dartmoor to the very intensive flocks on permanent grass on heavy soils. A brief look is made at the effects of health research over the last 50 years in the context of present problems and/or barriers to future efficiency. Also present production problems are examined, in particular those relating to coccidiosis and ‘ill thrift’. The problems of the field application of modern technology are considered in the areas of: (1) manipulation of the breeding season, in an attempt to even out the production curve, using sponges, PMS and melatonin and teaser rams; (2) manipulation of prolificacy, using fecundin and prolific hybrids; and (3) genetic manipulation/improvement, using Meat and Livestock Commission backfat/eye muscle recording schemes, sire referencing, AI and MOET.A scheme for the best utilization of veterinary surgeon/farmer relationship is outlined and mention is made as to the future direction of the industry as seen from the ‘sharp end’.

Full textAbstract:
Two densely sampled marine refraction lines were shot in northern Baffin Bay on the shelves of Devon and Ellesmere islands (North American plate) and Greenland (Greenland plate). A total of 11 ocean-bottom seismometers recorded the airgun signals. The processed data were analyzed by the use of ray tracing and amplitude modelling. Two-dimensional models were derived that reproduce the characteristics of the observed data. A 5 km deep sedimentary basin was identified on the south end of line 3. On both lines the crustal velocity has a range of 5.7–6.6 km/s. Midway along the line on the shelf of Devon and Ellesmere islands, the Moho shallows abruptly northward from 27 to 20 km. The thinned crust is not overlain by a sedimentary basin to compensate for the elevated Moho, suggesting this is not an extensional feature. The thickness of the crust adjacent to northwest Greenland increases from south (22 km) to north (37 km). The thickening occurs in two stages: a sharp increase in the depth to Moho northwest of the sedimentary basin followed by a gradual deepening to the end of the line. The thin crust on the shelf of Ellesmere Island is located adjacent to the thick crust of Greenland. Plate reconstructions based on regional magnetic anomalies and transform faults indicate that Greenland is a separate plate. The crustal structure revealed by seismic refraction and reflection profiles and the variations in the depth to Moho are consistent with the plate boundary occurring between the refraction lines.

Progress in politics and science often happens by accident. The unforeseen impact of the foot and mouth epidemic may fall into this category. Both the Ministry of Agriculture and vets were over-stretched dealing with the crisis and so badger culling, which was to have resumed on 1 May 2001, was suspended for a year; even routine TB testing of cattle is on hold.It seems probable that the Krebs/Bourne badger culling trial will be abandoned altogether. At least seven of the ten ‘triplet’ badger cull areas have been disrupted, particularly in Devon/Cornwall and Gloucestershire/Hereford. Some 600 of the 2900 badgers culled were in these two areas, perhaps 120 with TB, but only some 25 infectious. Since these were from some 400 km2, encompassing 450 farms, it is hard to see how the culls will have made the slightest impact on cattle TB.In fact it is already apparent that each TB badger has cost some £35000, which merely confirms the 1986 findings of the Dunnet Review that badger culls are a waste of money because they do not work. Professor McInerney, as part of the review, noted that ending badger culling was purely a political decision. If Labour had won the 1992 election, contingency plans were in place to end culls, but, sadly, by 1997 ‘New’ Labour decided it was politically safer to go ahead with the Krebs cull. Enough data ought to be available from the trial to concoct ‘scientific’ reasons to grasp the nettle and take the inevitable and long overdue decision politically to end this sorry farce, once and for all.

This paper describes the results from a project to date Early Bronze Age daggers and knives from barrows in south-west England. Copper alloy daggers are found in the earliest Beaker associated graves and continue to accompany human remains until the end of the Early Bronze Age. They have been identified as key markers of Early Bronze Age graves since the earliest antiquarian excavations and typological sequences have been suggested to provide dating for the graves in which they are found. However, comparatively few southern British daggers are associated with radiocarbon determinations. To help address this problem, five sites in south-west England sites were identified which had daggers and knives, four of copper alloy and one of flint, and associated cremated bone for radiocarbon dating. Three sites were identified in Cornwall (Fore Down, Rosecliston, Pelynt) and two in Devon (Upton Pyne and Huntshaw). Ten samples from these sites were submitted for radiocarbon dating. All but one (Upton Pyne) are associated with two or more dates. The resulting radiocarbon determinations revealed that daggers/knives were occasionally deposited in barrow-associated contexts in the south-west from c. 1900 to 1500 calbc.The dagger at Huntshaw, Devon, was of Camerton-Snowshill type and the dates were earlier than those generally proposed but similar to that obtained from cremated bone found with another dagger of this type from Cowleaze in Dorset: these dates may necessitate reconsideration of the chronology of these daggers

The new pandemic times reveal, besides the dysfunctions of the health system, a profound and prolonged shortage of material and human resources, as well as psychical blockages, fears and all kinds of weaknesses that we are now forced to confront, being alone with ourselves and inside ourselves. And what is it that causes these meetings, these long adjourned encounters? If it is true that being political means integrating into the superstructure of political consciousness of a state, then solidarity can be considered the first political gesture of the Academic Artistic Community in Iasi. At the end of the pandemic, the main function of this facility will be to recover the memory of an event that took place on a global scale. Equally, it could be the beginning of the study in a new type of theatrical performance, addressing post-pandemically people massively affected mentally, emotionally, physically, and cognitively.

Full textAbstract:
AbstractGround-penetrating radar (GPR) surveys at a center frequency of 500 MHz were used to determine winter (2007/08) and net annual (2005–07) snow water equivalent (SWE) patterns across the upper parts of Belcher Glacier, Devon Ice Cap, Nunavut, Canada. The GPR measurements were validated against snow depths determined from avalanche probe measurements, and converted to SWE values using densities measured with a down-borehole neutron density probe and in shallow snow pits. Distinct internal reflection horizons (IRHs) in the GPR record were formed during warm summers in 2007 and 2005, and a large rain event in summer 2006 which caused ice to accumulate above the 2005 melt surface. Elevation provides the dominant control on winter SWE distribution across the basin, with surface topography (e.g. gullies) also being locally important. Based on the location where IRHs intersected the ice-cap surface, the basin-wide firn line occurred at an altitude of 1260–1300 m over the period 2005–08. Net mass balance across the accumulation area of Belcher Glacier averaged 0.24 m w.e. a−1 over the period 2005–07, mainly dependent on altitude. This is a little higher than most previous estimates for the period since the 1960s, although the differences lie within error limits.

Full textAbstract:
INTRODUCTIONOn the 16 June 1982 a thresher shark, Alopias vulpinus (Bonnaterre, 1788), became entangled in a gill net at Bigbury Bay, S. Devon. The stomach contents were found to consist solely of teleost otoliths. The soft tissues of prey taken by large marine predators are often macerated and digested very rapidly or, as in this case, regurgitated during capture or stranding. Identification of the prey is therefore only possible from the hard parts which often remain, e.g. teleost otoliths, bones and scales, and cephalopod beaks, statoliths and gladiuses. The regular seasonal occurrences in the waters off south-west England and south-west Ireland make the thresher the most common of the large sharks in this area. Their accidental capture or collisions with nets are not rare and they have been taken by rod and line on several occasions.

The squat lobster Galathea strigosa (Linnaeus, 1760) (Galatheidae) was first described as Cancer strigosus by Linnaeus (1760: 495) from material collected by A. Martin “in Mari Norvegico” (Norwegian Seas) (inadvertently indicated in error as “southern Devon, England” by Baba et al. 2008). The species is widely-distributed in the northeastern Atlantic including the Mediterranean Sea and the name is in current and prevailing usage (see references cited below); it is also the type species of the highly speciose genus Galathea Fabricius, 1793 (Baba et al. 2008). The date of publication of Cancer strigosus is conventionally cited as 1761 (e.g., Baba et al. 2008: 78; Poore et al. 2011: xi). Evenhuis (1997: 478), however, showed that the publication in which the name Cancer strigosus was made available (i.e., Fauna Svecica sistens animalia Sveciae regni) was published before 14 November 1760. The date of publication of Cancer strigosus is therefore 1760.

The emergence of new performance paradigms in the second half of the twentieth century is only now being recognized as a fresh phase in human history. The creation of the new discipline, or, as some would call it, the anti-discipline of performance studies in universities is just a small chapter in a ubiquitous story. Everywhere performance is becoming a key quality of endeavour, whether in science and technology, commerce and industry, government and civics, or humanities and the arts. We are experiencing the creation of what Baz Kershaw here calls the ‘performative society’ – a society in which the human is crucially constituted through performance. But in such a society, what happens to the traditional notions and practices of drama and theatre? In this inaugural lecture, Kershaw looks for signs and portents of the future of drama and theatre in the performative society, finds mostly dissolution and deep panic, and tentatively suggests the need for a radical turn that will embrace the promiscuity of performance. Baz Kershaw, currently Professor of Drama at the University of Bristol, trained and worked as a design engineer before reading English and Philosophy at Manchester University. He has had extensive experience as a director and writer in radical theatre, including productions at the Drury Lane Arts Lab and with the Devon-based group Medium Fair, where he founded the first reminiscence theatre company Fair Old Times. His latest book is The Radical in Performance (Routledge, 1999). More recently he wrote about the ecologies of performance in NTQ 62.

This study suggests a new approach to EEG data classification by exploring the idea of using evolutionary computation to both select useful discriminative EEG features and optimise the topology of Artificial Neural Networks. An evolutionary algorithm is applied to select the most informative features from an initial set of 2550 EEG statistical features. Optimisation of a Multilayer Perceptron (MLP) is performed with an evolutionary approach before classification to estimate the best hyperparameters of the network. Deep learning and tuning with Long Short-Term Memory (LSTM) are also explored, and Adaptive Boosting of the two types of models is tested for each problem. Three experiments are provided for comparison using different classifiers: one for attention state classification, one for emotional sentiment classification, and a third experiment in which the goal is to guess the number a subject is thinking of. The obtained results show that an Adaptive Boosted LSTM can achieve an accuracy of 84.44%, 97.06%, and 9.94% on the attentional, emotional, and number datasets, respectively. An evolutionary-optimised MLP achieves results close to the Adaptive Boosted LSTM for the two first experiments and significantly higher for the number-guessing experiment with an Adaptive Boosted DEvo MLP reaching 31.35%, while being significantly quicker to train and classify. In particular, the accuracy of the nonboosted DEvo MLP was of 79.81%, 96.11%, and 27.07% in the same benchmarks. Two datasets for the experiments were gathered using a Muse EEG headband with four electrodes corresponding to TP9, AF7, AF8, and TP10 locations of the international EEG placement standard. The EEG MindBigData digits dataset was gathered from the TP9, FP1, FP2, and TP10 locations.

Abstract The Marselisborg WWTP (Aarhus, Denmark) fed the mainstream nitrification/denitrification tanks with excess sludge from a sidestream DEMON tank for more than three years to investigate if anammox can supplement conventional nitrification/denitrification in a mainstream of a temperate region. To evaluate this long-term attempt, anammox and also denitrification rates were measured in activated sludge from the main- and sidestream at 10, 20 and 30 °C using 15N-labelling (stable isotope) experiments. The results show that anammox contributes by approximately 1% of the total nitrogen removal in the mainstream tanks and that anammox conversion rates there are approximately 800–900 times lower than in the DEMON. A distinct temperature dependence of both anammox and denitrification rates was also confirmed, however, results from different temperatures did not significantly alter relative shares, e.g. anammox rates in activated sludge from the nitrification/denitrification tanks are also negligible at 30 °C. This indicates that the anammox bacteria abundance in the nitrification/denitrification tanks is too low to play an important role and that an adaptation to lower temperatures had not occurred. Additional in situ measurements in the nitrification/denitrification tanks further revealed that full nitrification dominates over partial nitritation. Dominant nitritation-anammox is therefore excluded per se and also nitrite shunt activities are not particularly supported.

AbstractThis article offers a cognitive theory of religious postulations of demonic beings in religious systems. I suggest a significant tension between a biological inheritance of moderate sexual promiscuity and the culturally imposed ideal of exclusive monogamy generates the salience of libidinous supernatural agents to human minds. I review sexual selection theory as applied to humans, the sexual proclivities of demonic cultural constructs, and survey the literature on demonic beings in religious systems. I offer statistical evidence of groupings of demon beliefs around the chief tension points suggested by sexual selection theory. I end with suggestions for further empirical testing of the theory.

Developmental biology and evolutionary biology are both mature integrative disciplines which started in the 19th century and then followed parallel and independent scientific pathways. Recently, a genetical component has stepped into both disciplines (developmental genetics and evolutionary genetics) pointing out the need for future convergent maturation. Indeed, the Evo-Devo approach is becoming popular among developmental biologists, based on the facts that distant groups share a common ancestry, that precise phylogenies can be worked out and that homologous genes often play similar roles during the development of very different organisms. In this essay, I try to show that the real future of Evo-Devo thinking is still broader. The evolutionary theory is a set of diverse concepts which can and should be used in any biological field. Evolutionary thinking trains to ask « why » questions and to provide logical and plausible answers. It can shed some light on a diversity of general problems such as how to distinguish homologies from analogies, the costs and benefits of multicellularity, the origin of novel structures (e.g. the head), or the evolution of sexual reproduction. In the next decade, we may expect a progressive convergence between developmental genetics and quantitative genetics.

AbstractThe steady-state flow model of Reeh (1988) is applied to a flow line that starts at the highest point of the Devon Island ice cap, follows the surface crest for 7.6 km, and then runs down the slope for a further 3.7 km. The effects of bedrock undulations, divergence of the flow lines, the variation of temperature with depth, and a basal layer of “soft” ice-age ice are taken into account. A flow law withn= 3 and a value ofAclose to that of Paterson (1981) is used. Longitudinal stress variations are neglected so that shear stress is calculated by the usual formula. It is estimated that these calculated values may be in error by at most 30%. Depth profiles of effective shear stress, and of the components of velocity and normal strain-rate, are presented at selected points along the flow line. These illustrate the large variations that occur near an ice divide and over bedrock undulations of amplitude comparable with the mean ice thickness. The model gives good predictions of the surface profile and of longitudinal and transverse surface strain-rates measured at ten points along the flow line. Predicted depth profiles of horizontal and vertical velocity components are compared with those measured in a bore hole. Comparison is limited by the fact that the model works in ice equivalent, whereas about 20% of the ice column consists of firn with different rheological properties from ice. The vertical velocity prediction is good. However, the model does not reproduce well the shape of the horizontal velocity profile, although measured and calculated fluxes differ only slightly. Predicted annual-layer thicknesses are within 15% of the measured ones in the upper half of the ice column, which consists of ice deposited in the last 1000 years. Predicted thicknesses in older ice are too small and the discrepancy increases with depth. This might indicate increased precipitation or, more likely, a thinner ice cap in the climatic optimum. However, it could also result from the fact that the layer of “soft” ice has been thinning continuously since the end of the ice age, so that the ice cap has never been in a steady state.

In this article Dirk Gindt discusses Ingmar Bergman's 1951 production of Tennessee Williams's The Rose Tattoo in the small Swedish town of Norrköping, demonstrating how Bergman methodically ignored the tragicomic nature of the play in order to develop and exaggerate its comic and grotesque elements. After extensive cuts and alterations in the script, the character Serafina delle Rose became even more overpowering than in the original text and dominated the action from beginning to end. Karin Kavli, a leading lady in Swedish post-war theatre and a frequent collaborator with Bergman, played the character not as a mourning widow but as a possessed disciple of Dionysus in an unabashedly entertaining and sexualized production which, despite reservations from critics, became a success with audiences. Dirk Gindt now works as a Postdoctoral Research Fellow at Stockholm University. He is co-editor of Fashion: an Interdisciplinary Reflection (Stockholm: Raster, 2009), and has published numerous articles in journals such as Nordic Theatre Studies, The Tennessee Williams Annual Review, Theatre Survey, and Fashion Studies, as well as chapters in edited volumes.

Nowadays we can witness, for example, debates about position, role and effect of digital mobile technologies, social networks, and many other issues on behaviour and performance of students. Suggestions about their place in science education are on a scale between transforming education toward digital technologies and calls to prohibit, at least some of them, on the other end. Unfortunately enough argumentation too many times follows patterns recognized as ‘The demon-haunted world’ (Sagan, 1995) and a vocabulary and argumentation in line with Frankfurt’s (2005) famous essay ‘On bullshit’.

Next, we discuss the role of information in thermodynamics that leads to the concept of Maxwell's Demon. Various Maxwell's Demons realized in single-electron circuits over the past couple of years are described. Currently, true quantum thermodynamics in superconducting circuits is a focus of attention, and we end the review by discussing the ideas and first experiments in this exciting area of research.

Full textAbstract:
Macrofaunal community structure was examined in a shallow sublittoral sea grass bed (Zostera marina L.) and adjacent unvegetated sediment in the River Yealm, Devon, south-west Britain, on a single sampling occasion in August 1995. The presence of Zostera had a significant influence on macrobenthic community structure in the River Yealm. Samples from inside the sea grass bed were characterized by significantly higher numbers of individuals and species, as well as by greater species richness and high faunal dominance (i.e. low evenness) compared with the unvegetated samples. High faunal dominance within the sea grass bed was attributable to the large numbers of a few species (e.g. the polychaetes juvenile capitellids, Spio filicornis, Exogone hebes, Nereis pelagica and the tanaidacean Apseudes talpa), while increased species richness was a result of a large number of additional rare (1–2 individuals) species. The greatest number of individuals was found in samples with the highest sea grass biomass. Multivariate ordination revealed a distinct separation of macrofauna communities from vegetated and unvegetated sites. Significance testing with ANOSIM shows that there were significant differences in community structure between vegetated and unvegetated habitats.

Full textAbstract:
The principle of homology is central to conceptualizing the comparative aspects of morphological evolution. The distinctions between homologous or non-homologous structures have become blurred, however, as modern evolutionary developmental biology (evo-devo) has shown that novel features often result from modification of pre-existing developmental modules, rather than arising completely de novo. With this realization in mind, the term ‘deep homology’ was coined, in recognition of the remarkably conserved gene expression during the development of certain animal structures that would not be considered homologous by previous strict definitions. At its core, it can help to formulate an understanding of deeper layers of ontogenetic conservation for anatomical features that lack any clear phylogenetic continuity. Here, we review deep homology and related concepts in the context of a gene expression-based homology discussion. We then focus on how these conceptual frameworks have profited from the recent rise of high-throughput next-generation sequencing. These techniques have greatly expanded the range of organisms amenable to such studies. Moreover, they helped to elevate the traditional gene-by-gene comparison to a transcriptome-wide level. We will end with an outlook on the next challenges in the field and how technological advances might provide exciting new strategies to tackle these questions. This article is part of the themed issue ‘Evo-devo in the genomics era, and the origins of morphological diversity’.

Full textAbstract:
Development and evolution of animal behaviour and morphology are frequently addressed independently, as reflected in the dichotomy of disciplines dedicated to their study distinguishing object of study (morphology versus behaviour) and perspective (ultimate versus proximate). Although traits are known to develop and evolve semi-independently, they are matched together in development and evolution to produce a unique functional phenotype. Here I highlight similarities shared by both traits, such as the decisive role played by the environment for their ontogeny. Considering the widespread developmental and functional entanglement between both traits, many cases of adaptive evolution are better understood when proximate and ultimate explanations are integrated. A field integrating these perspectives is evolutionary developmental biology (evo-devo), which studies the developmental basis of phenotypic diversity. Ultimate aspects in evo-devo studies—which have mostly focused on morphological traits—could become more apparent when behaviour, ‘the integrator of form and function’, is integrated into the same framework of analysis. Integrating a trait such as behaviour at a different level in the biological hierarchy will help to better understand not only how behavioural diversity is produced, but also how levels are connected to produce functional phenotypes and how these evolve. A possible framework to accommodate and compare form and function at different levels of the biological hierarchy is outlined. At the end, some methodological issues are discussed.

In a now classic paper published in 1991, Alberch introduced the concept of genotype–phenotype (G→P) mapping to provide a framework for a more sophisticated discussion of the integration between genetics and developmental biology that was then available. The advent of evo-devo first and of the genomic era later would seem to have superseded talk of transitions in phenotypic space and the like, central to Alberch's approach. On the contrary, this paper shows that recent empirical and theoretical advances have only sharpened the need for a different conceptual treatment of how phenotypes are produced. Old-fashioned metaphors like genetic blueprint and genetic programme are not only woefully inadequate but positively misleading about the nature of G→P, and are being replaced by an algorithmic approach emerging from the study of a variety of actual G→P maps. These include RNA folding, protein function and the study of evolvable software. Some generalities are emerging from these disparate fields of analysis, and I suggest that the concept of ‘developmental encoding’ (as opposed to the classical one of genetic encoding) provides a promising computational–theoretical underpinning to coherently integrate ideas on evolvability, modularity and robustness and foster a fruitful framing of the G→P mapping problem.

AbstractInterpretation of ice mass elevation changes observed by satellite altimetry demands quantification of the proportion of elevation change which is attributable to variations in firn densification. Detailed stratigraphic logging of snowpack structure and density was carried out at ~1km intervals along a 47 km transect on Devon Ice Cap, Canada, in spring (pre-melt) and autumn (during/ after melt) 2004 and 2006 to characterize seasonal snowpack variability across the full range of snow facies. Simultaneous meteorological measurements were gathered. Spring (pre-melt) snowpacks show low variability over large spatial scales, with low-magnitude changes in density. The end-of-summer/ autumn density profiles show high variability in both 2004 and 2006, with vastly different melt regimes generating dissimilar patterns of ice-layer formation over the two melt seasons. Dye-tracing experiments from spring to autumn 2006 reveal that vertical and horizontal distribution of meltwater flow within and below the annual snowpack is strongly affected by the pre-existing, often subtle stratigraphic interfaces in the snowpack, rather than its bulk properties. Strong interannual variability suggests that using a simple relationship between air temperature, elevation and snowpack densification to derive mass change from measurements of elevation change across High Arctic ice caps may be misguided. Melt timing and duration are important extrinsic factors governing snowpack densification and ice-layer formation in summer, rather than averaged air temperatures.

The beginning of the end of the demons of consent. Coming to terms with ideologisation in Slovak cultureThe first part of the article focuses on demonstrating the process of ideologisation in Slovak culture after 1948, i.e. after the beginning of communist rule. This reveals the initial fascination with the idea of communism among the creative community and its gradual enslavement. Additionally, on the one hand it examines the results of repressive measures of power, and on the other it looks at conformist intellectual circles. The second half discusses how Dominik Tatarka, a leading Slovak intellectual, deals with the mechanisms of cultural ideologisation and writers’ attitudes, which concluded in his fictional-political-autobiographical novel Demon of Consent (Démon súhlasu). This work reveals the writer’s strategy to show how the experience of totalitarianism fits with the concept of biblical eschatology. The writer does not, however, ignore the different idealised communist conceptualisations of the era, and often incorporates and combines visions of the tragic, ironic and sometimes grotesque. Finally, the article also takes into account the wider context of the writer’s changes in attitude and their consequences. Początek końca demonów zgody.

Full textAbstract:
The δ18O record from ice cores serves as a proxy paleoclimatic temperature record, through the association of isotopic ratio to air temperatures at time of precipitation. Climatic change may be preserved also as a signal in ground temperatures, not as a proxy indicator of past climate but as a direct consequence of the effect of past air temperature variations and associated physical processes at the ground surface. In the Canadian Arctic Archipelago, δ18O records are available from the Devon and Agassiz ice caps, and precision ground temperatures to depths of up to 1000 m are available from 40 petroleum exploration wells, about one third of which are suitable for paleoenvironmental reconstruction. There is an opportunity to compare these two methods of looking at the paleoenvironment, and to show how complementary they are to each other. Geothermal analysis is predicated on the fundamental hypothesis that the terrestrial heat flow, which arises largely from the decay of radioactive elements within the crust, does not vary measurably in the upper few km. But at many wells, the heat flow, calculated as the product of the measured temperature gradient and rock thermal conductivity, does vary systematically with depth in the well. While more random variations may be attributed to measurement errors, and corrections may be made for such known effects as local topography, the residual coherent “long wavelength” variation may be ascribed to effects arising from climate change. Can we, then, determine whether a particular temperature history is consistent with the geothermal record, or ideally, invert the geothermal data to reveal a record of past surface temperatures? Attempts with varying success at paleoclimatic reconstruction from ground temperatures have been reported in the literature (e.g. Lane, 1923; Hotchkiss and Ingersoll, 1934; Birch, 1948; Cermak, 1971; Vasseur and others, 1983; Lachenbruch and others, 1986) and from temperature profiles in ice sheets (e.g. Paterson, 1968; Weertman, 1968; Budd and Young, 1982). In this study, standard techniques in geothermics (e.g. Jaeger, 1965) have been used (1) to show the effect of any hypothesized surface paleotemperature model upon subsurface temperatures, or (2) on the hypothesis that the variation in heat flow is attributed to paleoclimatic effects, to derive a surface temperature model at each well that minimizes the variation in a statistical sense. The resolution of the method and limitations in our measured temperature and rock thermal conductivity data restrict the application of the second method to the past few hundred to one thousand years. The paper considers the first approach for the period 1 ka-10 kaB.p. at about a dozen wells and gives an example of the second approach at a well west of the Agassiz Ice Cap. Aproach (1). In studying the Devon Island ice core, Fisher and Koerner (1979) present a detailed record of the mean annual air temperature at the site throughout the Holocene, based on the δ18O record. A simplified time-temperature model of this record is applied to the ground temperature data set for the period 1 ka-10 ka B.P. Although the effect on the ground temperatures is only subtly perceptible, the model has the effect of reducing the apparent climatically-related curvature in the data, as reflected in an improvement in the standard deviation in the calculated heat flow profile by 5% to 30%. Hence, the geothermal record provides quantitative support for Holocene climatic information derived from the ice core record. Approach (2). This inversion technique is analogous to Paterson’s (1968) reconstruction of the surface temperature during the past century from a temperature profile taken in the small Meighen Ice Cap, Arctic Canada. A unique model is not obtained; rather, a small set of possible surface temperature variations consistent with the deeper subsurface temperatures is produced. Such modelling suggests that subsurface temperatures at a well 180 km west of the Agassiz Ice Cap are consistent with ground surface temperatures some 4–6 Κ lower at the well during the Little Ice Age; this is considerably more severe than the mean annual air temperatures projected from the δ18O record at Agassiz. It is possible that the large increase in ground surface temperature at the wellsite since the Little Ice Age may be attributed to some climatically-related phenomena such as increased incidence of snow cover coherent with the changing climate. A well on Devon Island is not deep enough for a comparison to that ice cap. The oxygen isotope data provide a valuable estimate of Holocene climate with which to correct ground temperature data for terrestrial heat flow, or other studies. However, examination of the signal of more recent events suggests that ground temperatures may be considerably modified by associated transient phenomena such as snow cover, vegetation, etc. Hence, one would expect that such a Holo¬cene correction might either understate or overstate the actual experience of the ground surface at a site.

While more random variations may be attributed to measurement errors, and corrections may be made for such known effects as local topography, the residual coherent “long wavelength” variation may be ascribed to effects arising from climate change.Can we, then, determine whether a particular temperature history is consistent with the geothermal record, or ideally, invert the geothermal data to reveal a record of past surface temperatures? Attempts with varying success at paleoclimatic reconstruction from ground temperatures have been reported in the literature (e.g. Lane, 1923; Hotchkiss and Ingersoll, 1934; Birch, 1948; Cermak, 1971; Vasseur and others, 1983; Lachenbruch and others, 1986) and from temperature profiles in ice sheets (e.g. Paterson, 1968; Weertman, 1968; Budd and Young, 1982).In this study, standard techniques in geothermics (e.g. Jaeger, 1965) have been used (1) to show the effect of any hypothesized surface paleotemperature model upon subsurface temperatures, or (2) on the hypothesis that the variation in heat flow is attributed to paleoclimatic effects, to derive a surface temperature model at each well that minimizes the variation in a statistical sense. The resolution of the method and limitations in our measured temperature and rock thermal conductivity data restrict the application of the second method to the past few hundred to one thousand years. The paper considers the first approach for the period 1 ka-10 kaB.p. at about a dozen wells and gives an example of the second approach at a well west of the Agassiz Ice Cap.Aproach (1). In studying the Devon Island ice core, Fisher and Koerner (1979) present a detailed record of the mean annual air temperature at the site throughout the Holocene, based on the δ18O record. A simplified time-temperature model of this record is applied to the ground temperature data set for the period 1 ka-10 ka B.P. Although the effect on the ground temperatures is only subtly perceptible, the model has the effect of reducing the apparent climatically-related curvature in the data, as reflected in an improvement in the standard deviation in the calculated heat flow profile by 5% to 30%. Hence, the geothermal record provides quantitative support for Holocene climatic information derived from the ice core record.Approach (2). This inversion technique is analogous to Paterson’s (1968) reconstruction of the surface temperature during the past century from a temperature profile taken in the small Meighen Ice Cap, Arctic Canada. A unique model is not obtained; rather, a small set of possible surface temperature variations consistent with the deeper subsurface temperatures is produced. Such modelling suggests that subsurface temperatures at a well 180 km west of the Agassiz Ice Cap are consistent with ground surface temperatures some 4–6 Κ lower at the well during the Little Ice Age; this is considerably more severe than the mean annual air temperatures projected from the δ18O record at Agassiz. It is possible that the large increase in ground surface temperature at the wellsite since the Little Ice Age may be attributed to some climatically-related phenomena such as increased incidence of snow cover coherent with the changing climate. A well on Devon Island is not deep enough for a comparison to that ice cap.The oxygen isotope data provide a valuable estimate of Holocene climate with which to correct ground temperature data for terrestrial heat flow, or other studies. However, examination of the signal of more recent events suggests that ground temperatures may be considerably modified by associated transient phenomena such as snow cover, vegetation, etc. Hence, one would expect that such a Holo¬cene correction might either understate or overstate the actual experience of the ground surface at a site.

AbstractThere is evidence that, in cattle, rapid compensatory growth after a period of growth restriction may increase the variability of beef quality and that variability is greater in breeds which reach larger body size at maturity. This experiment investigated the effect of compensatory growth following a period of winter growth restriction on carcass quality in steers of small and large mature size grazed on pasture. Angus (no. = 120) and South Devon ✕ Angus (SD✕ A; no. = 110) steers were allocated to non-restricted or restricted growth treatment groups and for 126 days over winter their grazing was managed to achieve mean live-weight gains of approximately 0·7 kg/day or to maintain live weight for each group respectively. Steers were slaughtered at the start (no. = 10 per breed) and end (no. = 20 per nutrition group (10 from each breed)) of the winter period for carcass evaluation. Thereafter, remaining steers were grazed together at a high pasture allowance to maximize growth and were slaughtered for carcass evaluation as they reached target live weights (Angus, 590 kg; SD✕ A, 620 kg). SD✕ A steers grew faster (P< 0·05) during both the winter and finishing periods and reached target slaughter live weights approximately 20 days earlier than Angus steers. SD✕ A steers also had leaner carcasses than Angus steers at each slaughter although there was no significant difference in meat quality between breeds. However, there was a significant effect of restriction treatment on carcass weight and meat quality. The non-restricted steers grew faster, had heavier carcasses and more tender steaks than restricted steers, although there was no significant difference in carcass fatness (adjusted for hot carcass weight). Muscle calpain activities were positively correlated with live-weight gain during the finishing period suggesting increased potential for post-mortem myofibrillar proteolysis and therefore increased meat tenderness. However, in the present experiment this was confounded by an increase in shear force with age-at-slaughter, especially in the non-restricted steers. Nevertheless, steers which were heaviest at the start of the experiment reached slaughter live weight earliest, were leaner than average and had higher calpain system activities at slaughter regardless of breed or restriction treatment. Furthermore, in the non-restricted group, high initial live weight and early slaughter was associated with lower pH and more tender meat. In conclusion, although restriction affected meat quality attributes, it appears that live weight prior to food restriction also had a considerable effect on carcass characteristics at slaughter. Therefore, the characteristics of the early growth phase prior to the finishing period may have important consequences for meat quality.

Governance in the English regions has been undermined and weakened by recent structural changes. Although well established during the New Labour era, the regional level of governance in England did not survive the post-2010 process of institutional churn shaped by economic austerity and central government’s aversion to the regional level. This has subsequently led to rescaling to the sub-regional level and the introduction of devolution ‘deals’ involving new combined authorities with elected mayors. This article looks at the experience of North East England, where regional structures have been broken up and the region disempowered by such changes. It reviews what has happened to governance in the North East over the past 20 years and discusses why the dismantling of regional governance matters. While the region’s external relationships with central government are problematic, it is also argued that governance problems within the region are no less important and need reforming. Longitudinal research indicates that organisations providing public services in the North East have continued to be characterised by inadequate accountability, unrepresentative governance and lack of transparency. The combined effects of the devolutionary consequences of Brexit and the ineffectiveness of small-scale ‘devo-deal’ interventions mean that the ‘Regionalist case’ in England will need to be refashioned and restated. The article concludes by considering the case for reintroducing regional-level governance and points to ways of bolstering the accountability and effectiveness of this level of sub-national governance.

The surface-generation models for the microendmilling process developed in Part I (Liu, DeVor, and Kapoor, 2007, J. Manuf. Sci. Eng., 129(3), pp. 453–460) are experimentally calibrated and validated. Partial immersion peripheral downmilling and full-immersion slotting tests are performed over a wide range of feed rates (0.25–12μm∕flute) using two tools with different edge radii (3μm and 2μm) and runout levels (2μm and 3μm) for the investigation of sidewall and floor surface generation, respectively. The deterministic models are validated using large feed-rate tests with errors within 18% for both sidewall and floor surfaces. For low feed-rate tests, the stochastic portion of the surface roughness data are determined from the observed roughness data and the validated deterministic model. The stochastic models are then calibrated and validated using independent data sets. The combination of the deterministic and stochastic models predicts the total surface roughness within 15% for both the sidewall and floor surface over a range of feed rates. The models are then used to simulate micromachined surfaces under a variety of conditions to gain a deeper understanding of the effects of tool geometry (edge radius and edge serration), process conditions, tool tip runout, process kinematics and dynamics on the machined surface roughness.

The article analyzes the events that led to the beginning of the Second Anglo-Afghan War (1878-1881). In particular, the military and political side of the Anglo-Russian conflict at the final stage of the Eastern crisis (1875-1878) is sub-jected to a more detailed study. The author examines in details a particular episode – the departure to Afghanistan in the summer of 1878 the diplomatic mission of Major-General N. G. Stoletov to conclude an alliance against England, which was accompanied with a military demon-stration of the Russian army in relation to British India. Based on the comparison of the domestic and foreign researcher’s points of view, as well as by involving various groups of historical sources, an attempt is made to give an objective assessment of these events and to identify their influence on the genesis of the second Anglo-Afghan war, which became a natural consequence of the Anglo-Russian rivalry in the East at the end of the XIX century.

Full textAbstract:
The problem of the effectiveness of obstruction at the level of the aortic arch is still a matter of discus-sion in the modern literature. Traditionally, by excision of the coarctation part, in the presence of hypoplasia, the incision is extended to a narrowed area and a modification of the classical end-to-end anastomosis is applied in the form of an elongated or expanded variant. Recently, when proximal part is involved in the pathological process, cardiac surgeons have been more likely to use median sternotomy using other types of plastic surgery, including dilation of the narrowed area with a pericardial patch, or pulmonary artery tissue. Accordingly, the analysis of the results of the use of end-to-end anastomosis in young children with aortic arch hypoplasia, especially in view of long-term survival and the level of reoperation, is an important issue of neonatal cardiac surgery.
The aim. To evaluate the effectiveness of the use of an extended end-to-end anastomosis after reconstruction of the aortic arch in children under 1 year of age.
Materials and methods. The study material included 348 infants who underwent surgical correction of aortic arch hypoplasia through the method of extended end-to-end anastomosis from 2010 to 2020. The operations were performed at the National Amosov Institute of Cardiovascular Surgery of the NAMS of Ukraine and the Ukrainian Children’s Cardiac Center. The study group included only patients with two-ventricular physiology. There were 233 male patients (67%) and 115 female patients (33%). The mean age was 1.07 (0.20; 2.30) months, the mean weight was 3.89 (3.30; 4.90) kg, the mean body surface area was 0.23 (0.20; 0.28) m2. Diagnosis of aortic arch hypoplasia was based on two-dimensional echocardiography.
Results. According to echocardiography, after surgery there was a significant decrease in the pressure gradient in the aortic arch from 48.3 ± 20.3 to 16 ± 6.9 (p<0.05), left ventricular PV increased significantly from 61.6 ± 12% to 66.3 ± 6.4% (p> 0.05). The hospital mortality was 1.7% (n = 6). The causes of mortality were not related to the end-to-end aortic arch technique. The duration of follow-up period ranged from 1 month to 9.3 years. Two deaths occurred in the follow-up period. Thirty-two (9.1%) patients developed aortic arch restenosis in the postoperative period. Balloon dilatation of restenosis was performed in 21 patients. Eleven patients underwent repeated aortic arch repair surgery through the median sternotomy. There were no central nervous system complications in the follow-up period.
Conclusions. The use of an extended end-to-end anastomosis in the surgical treatment of aortic arch hypoplasia demon strates low hospital mortality and high long-term survival. Indications for the effective use of this type of reconstruction are hypoplasia of the isthmus and distal aortic arch.

Biostratigraphical ranges and palaeogeographical distribution of mid-Givetian to end-Frasnian odontopleurids are investigated. The discovery of Leonaspis rhenohercynica sp. nov. in mid-Givetian strata extends this genus unexpectedly up to the late Middle Devonian. New material of Radiaspis radiata (Goldfuss, 1843) and the first koneprusiine in Britain, Koneprusia? sp., are described from the famous Lummaton shell-bed, Torquay, Devon. New taxa of Koneprusia, K. serrensis, K. aboussalamae, K. brevispina, and K. sp. A and K. sp. B are defined. Ceratocephala (Leonaspis) harborti Richter & Richter, 1926, is revised and reassigned to Gondwanaspis Feist, 2002. Two new species of Gondwanaspis, G. dracula and G. spinosa, plus three others left in open nomenclature, are described from the late Frasnian of Western Australia. A further species of Gondwanaspis, G. prisca, is described from the early Frasnian of Montagne Noire. Species of Gondwanaspis are shown to possess a number of paedomorphic features. A functional analysis suggests that, unlike other odontopleurids, Gondwanaspis actively fed and rested with the same cephalic orientation. The sole odontopleurid survivors of the severe terminal mid-Givetian biocrisis (‘Taghanic Event’) belong to the koneprusiine Koneprusia in the late Givetian and Frasnian, and, of cryptogenic origin, the acidaspidine Gondwanaspis in the Frasnian. Whereas the former became extinct in the late Frasnian at the Lower Kellwasser Event, the latter disappeared, and with it the entire Odontopleuroidea, at the terminal Frasnian Upper Kellwasser global biocrisis.

This research explores the ways cannibalism in Chuck Palahniuk’s novel Haunted (2005) and Nicolas Winding Refn’s film The Neon Demon (2016) are a consequence, and reflective, of the consuming nature of creative industries. The research draws from this exploration that the consumptive characteristics of cannibalism often allegorise the processes and careers of artists. Specifically, the sacrificial nature of putting oneself into one’s work, the notion of the tortured artist, and the competitive nature of creative industries, where the hierarchy is ascended through others’ losses.
In the framing narrative of Haunted, seventeen writers are trapped within an isolated writing retreat under the illusion of re-enacting the Villa Diodati and writing their individual masterpieces. When inspiration fails them, they sabotage their food supply in order to enhance their suffering, and thus their eventual memoirs. The writers turn to cannibalism, not only to survive but to remove the competition. By consuming each other, they attempt to manufacture themselves as ‘tortured artists’, competing to create the most painful story of the ‘writing retreat from hell’.
In The Neon Demon, the protagonist, Jesse, begins as an innocent young woman who becomes embroiled in the cutthroat modelling industry. Favoured for her natural beauty, Jesse antagonises her fellow models, developing narcissistic tendencies in the process. At the film’s end she is cannibalised by these rivals, indicating the industrial consumption of her purity, the restoration of individual beauty by leeching off of the young, and the retaining of the hierarchy by removing the competition.
Employing close readings of both literary and cinematic primary source material, this interdisciplinary study investigates a satirical trend within cultural representations of cannibalism against consumptive and competitive creative industries. In each text, cannibalism manifests as a consequence of these industrial pressures, as the desire for fame forces people to commit unsavoury deeds. In this regard, cannibalism acts as an extreme extrapolation of the dehumanising consequences of working within this capitalist confine.

Full textAbstract:
We have addressed the seismic data denoising problem, in which the noise is random and has an unknown spatiotemporally varying variance. In seismic data processing, random noise is often attenuated using transform-based methods. The success of these methods in denoising depends on the ability of the transform to efficiently describe the signal features in the data. Fixed transforms (e.g., wavelets, curvelets) do not adapt to the data and might fail to efficiently describe complex morphologies in the seismic data. Alternatively, dictionary learning methods adapt to the local morphology of the data and provide state-of-the-art denoising results. However, conventional denoising by dictionary learning requires a priori information on the noise variance, and it encounters difficulties when applied for denoising seismic data in which the noise variance is varying in space or time. We have developed a coherence-constrained dictionary learning (CDL) method for denoising that does not require any a priori information related to the signal or noise. To denoise a given window of a seismic section using CDL, overlapping small 2D patches are extracted and a dictionary of patch-sized signals is trained to learn the elementary features embedded in the seismic signal. For each patch, using the learned dictionary, a sparse optimization problem is solved, and a sparse approximation of the patch is computed to attenuate the random noise. Unlike conventional dictionary learning, the sparsity of the approximation is constrained based on coherence such that it does not need a priori noise variance or signal sparsity information and is still optimal to filter out Gaussian random noise. The denoising performance of the CDL method is validated using synthetic and field data examples, and it is compared with the K-SVD and FX-Decon denoising. We found that CDL gives better denoising results than K-SVD and FX-Decon for removing noise when the variance varies in space or time.

Interest in vitamin D and the VDR gene is increasing as putative roles in human health and evolutionary processes are explored. This review looks beyond the classic biochemistry that links vitamin D to calcium homeostasis; it explores how vitamin D interacts with light in a broader perspective than simple skin photosynthesis. It examines how the vitamin influences circadian rhythm, and how it may have helped drive the evolution of skin pigmentation. To this end, the nutrient–nutrient relationship with folate is also explored. The VDR gene is additionally examined as a factor in the evolutionary selection of skin depigmentation at higher latitudes to allow vitamin D synthesis. Evidence is given to show that VDR polymorphisms exhibit a latitudinal gradient in allele prevalence consistent with such a paradigm. Overall, the review examines new evo-devo ideas that link light-sensitive vitamins to human health/phenotype, both within and across the lifecycle.

Native doctoral students are a severely underrepresented group in higher education with stagnating enrollment trends over the last 30 years when compared to other racial/ethnic groups. For Native women doctoral students specifically, they represent only 0.9% (n=119) in 2002-03 (DeVoy, Darling- Churchill, & Snyder, 2008). Connected to the lack of representation at a doctoral level, their unique intersectional experiences are largely ignored in research. Using (in)visibility, cultural integrity, and counter-storytelling, this Indigenous qualitative (e.g., sharing circles) study explores three Native women doctoral students’ documented lived experiences via social media as they navigated through the doctoral and dissertation writing process. Through scholarly personal narrative analyses of Facebook, Instagram, and Twitter posts and virtual sharing circles, early career Native scholars discuss managing visibility, maintaining cultural integrity, and using social media as a means for strengthening relationships and empowering resistance to oppressive university structures. While social media was important in helping Native women doctoral students, institutions must incorporate Native culture and perspectives when seeking ways to advance Native doctoral degree recipients.

This paper will explore child health care and treatment seeking behavior of villagers and presents factors that discourage them from using public health facilities. The perspective of human health is not only stay behind in the contact between the disease and the human body and the extermination of the demon by providing few medicines rather it is a complex web where multiple factors are affecting human to live a sound life. The environment has a diverse effect on human life: some indulge humans with it extravaganza while some impose serious theaters but one thing in common, every environment shares basic problems of acquiring and allocating space, food, energy and resources for health. Haor people have endless problems to meet, starting from food to basic human rights. Maintaining a healthy life does end up with some formality of going to some popular and folk treatment though going to professionals is rare. Government and non-Governmental organizations have a variety of scope to improve the situation by providing health infrastructure, awareness building measures, eradicating superstition and including health education in the school curriculum.
