description: The G6 giant HR\,2582 (HD\,50890) was observed by CoRoT for approximately 55 days. Mode frequencies are extracted from the observed Fourier spectrum of the light curve. Numerical stellar models are then computed to determine the characteristics of the star (mass, age, etc...) from the comparison with observational constraints. We provide evidence for the presence of solar-like oscillations at low frequency, between 10 and 20\,$μ$Hz, with a regular spacing of $(1.7\pm0.1)μ$Hz between consecutive radial orders. Only radial modes are clearly visible. From the models compatible with the observational constraints used here, We find that HR\,2582 (HD\,50890) is a massive star with a mass in the range (3--\,5\,$M_{\odot}$), clearly above the red clump. It oscillates with rather low radial order ($n$ = 5\,--\,12) modes. Its evolutionary stage cannot be determined with precision: the star could be on the ascending red giant branch (hydrogen shell burning) with an age of approximately 155 Myr or in a later phase (helium burning). In order to obtain a reasonable helium amount, the metallicity of the star must be quite subsolar. Our best models are obtained with a mixing length significantly smaller than that obtained for the Sun with the same physical description (except overshoot). The amount of core overshoot during the main-sequence phase is found to be mild, of the order of 0.1\,$H_{\rm p}$.

Efficacy of tebuconazole and ddac in shell-treated wood

description: In 2008, the Canadian standard for decking installed above ground was revised, and the penetration requirement was eliminated. This decision was based on field test data and fundamental work on mobility of copper in the preservative formulations that dominated the market at the time. Recently the wood protection industry has shown interest in shifting towards carbon-based preservatives. Thus, it is important to test the efficacy of carbon-based preservative formulations as shell-treatments on Canadian wood species. In this study, samples of spruce heartwood were treated with a formulation containing either tebuconazole or didecyldimethylammonium carbonate (DDAC). The treated wood was exposed outdoors for one year and the leachate from these samples was collected. Tebuconazole and DDAC were detected in the leachate collected, and this indicates that these active ingredients were mobile in the wood after treatment. DDAC was detected in very low concentrations on wood surfaces that were untreated before exposure: 0.03 mg DDAC/g of wood and 0.02 mg of DDAC/g wood were measured for the high and low retentions respectively. The concentration of tebuconazole detected was not different from the control samples. This suggests that mobile DDAC may be able to re-deposit in the wood, but tebuconazole does not re-deposit once it is dislodged from the wood. Furthermore, results showed that spores of Gloeophyllum sepiarium and Oligoporus placentus were able to germinate on untreated check surfaces within 2 weeks on samples collected from exposed, treated wood. This indicates that the re-deposited carbon-based active ingredients were not able to protect the untreated check surfaces against germination of basidiospores of some common fungi isolated from above-ground decking in Canada.

description: On July 12 of 1985 at Saint-Étienne, France, Luis Alberto ‘Lucho’ Herrera, the first Colombian cyclist to have won a Tour de France stage (1984), became an international hero and a national martyr. Not only did the image of Herrera’s bloodied face staring at the horizon after winning the 14th stage acquire cult status within cycling circles around the world, it also established a subtle, yet passionate, connection between the figure, his performance, and Colombian reality. We argue that Herrera’s image worked as a metaphorical extension that stimulated the association between Herrera’s martyred image and the collective struggle people had to go through on a daily basis, accentuating the strongly Catholic iconographic dimension attached to popular sport practices in Colombia (faith, endurance, and suffering). Using applied elements of Charles S. Peirce’s semiotic apparatus, this paper analyze three symbolic elements embedded in Herrera’s image – blood, struggle, and redemption – to discuss the photograph’s power to resonate with the average Colombian at a time when narco terrorism ruled most of the territory and the escalation of insurgency and paramilitary violence were daily occurrences.

description: Abstract: A market survey involving 100 grain consumers who were randomly selected in two markets, was conducted to examine their awareness of chemical preservatives in the study. The respondents in the two markets, Choba and Wokem in Port Harcourt was interviewed to examine their awareness of chemical preservatives in pulse crops, addressing growing concerns about food safety and health implications.  The study utilized primary data which was collected through the use of questionnaire from the respondents and personal observation by the researchers.  A semi structured standardized questionnaire was administered to the respondents to gather information about their socio demographic characteristics, knowledge, and attitude of the traders/consumers on nutrition and food preservation. Data were analyzed using ANOVA and descriptive statistics such as frequency distributions, percentages, mean score and correlation coefficient. However, questionnaires administered to farmers revealed that above 40% regularly employed chemical pesticides, notably Methylbromide and Phostoxin, with a preference for metal containers in grain storage and the seller/consumers above 36 years old consumes more of the grains. Only 65% of respondents are aware that grains bought are usually preserved with banned chemicals (gammalin 20, carbide etc) and health risks associated with consuming the treated grains.  Binary logistic regression of factors results shows that the only significant factor in   this model is education status (p = 0.028), which shows that respondents with higher education are significantly more likely to be aware of health risks associated with consuming treated goods (B = 1.402). With the global rise in agricultural pesticide use to maximize crop yield, consumers and regulatory bodies have raised alarms over potential health risks mainly cancer from pesticide accumulation in food. These results highlight the need for stricter pesticide application guidelines and regular monitoring to ensure consumer safety and food quality.
The Iconicity of an ‘Immigrant Writer’

description: What do Jonas Hassen Khemiri from Sweden and Yahya Hassan from Denmark have in common? Apart from the visual commonalities – they both have a non-white physical appearance – they share an outstanding commercial and critical success. Using these young, highly hyped, bestselling authors as examples, this paper aims at discussing the iconic function of the ‘immigrant writer’s’ authentic body in the public discourse on ‘national’ and ‘immigrant’ identities. The emphasis lies on the marketability of an ‘immigrant writer’, which derives its commercial value from the iconicity based on ethnic visibility, recognizability and exemplarity. I want to draw a connection between the existing fixed iconography of an ‘immigrant’ in the mass media and the visual ethnicized representations of Khemiri and Hassan in the daily press and put their literary performance into the socio-political context. This paper considers their popular author-images as objected icons of hegemonic normative discourses on national culture, while it simultaneously understands their subversive literary and extra-textual renegotiations of national self-imagery as iconoclasms of traditional order of ‘Swedishness’ resp. ‘Danishness’. Rather than going into deep textual analysis, I focus on the para-texts such as newspaper articles and book covers as iconic performances of the discourse on the ‘immigrant literature’.

description: We develop a QED approach to find the contribution of the quantum vacuum to the electromagnetic Abraham force. Semi-classical theories predict diverging contributions from the quantum vacuum. We show that the divergencies disappear by Kramers-Bethe mass-renormalization. The finite remainder is compared to the relativistic corrections to the Abraham force. This work generalizes an earlier paper [1], dedicated to the harmonic oscillator, to the hydrogen atom and corrects two subtle errors.

description: This qualitative research study presents descriptive and explanatory multiple case analyses offering a description and analysis on relational decision making among school district leaders responding to a district wide videoconferencing policy. This exploratory study was conducted using an interpretive mixed method multiple case approach. Interviews and document analyses were the primary data sources used to collect data. Eleven rural principals, five urban principals and five district administrators were interviewed using a semi-structured interview guide. Network analysis, Bates ACTIONS model (2000) and Brazer & Keller (2006) multiple stakeholder decision making models formed the conceptual framework for the data collected. The range of documents included annual reports, board meeting minutes and policy drafting. Triangulation of the data (Patton, 2002) contributed to the validity and credibility of the data analysis. Among the leaders studied, the network formed as a know-how network of influence. The rural leaders’ network emerged as an inflexible thin network where information exchange limited network capacity. The urban and district leaders’ network emerged as a dense tightly closed network. For rural leaders, learner impact from the videoconferencing influenced decision makers most. Cost influenced urban decision makers most. The district leaders considered organizational impact as their most important decision making factor. Instructional and curriculum decisions were the top decision making task for rural leaders. Strategic resourcing was the top decision making task for urban leaders. The district leaders ranked centralized and decentralized decision making as their top ranked decision making task. Rural leaders used student learning, school process and perception data to guide their decision making with implementation. The urban leaders used solely student learning data. The district leaders used student learning and school process data. Rural leaders used type 2 and type 3 collaborative decision making style within staff meeting and school council structure. Urban leaders used type 2 and type 4 collaborative decision making style within a committee structure. District leaders used type 1, type 2 and type 4 collaborative decision making style within a committee structure when involving others in shared leadership.

description: The expansion of Bantu-language speakers is the most dramatic demographic event in Late Holocene Africa, which fundamentally re-shaped the linguistic, cultural and biological landscape of the continent. With the largest genomic dataset to date of Bantu-speaking populations, including newly generated data of modern-day and ancient DNA from previously unsampled regions in Africa, we contribute new insight into this expansion that started 6,000-4,000 years ago in western Africa. We have genotyped 1,763 participants, including 1,526 Bantu speakers from 147 populations across 14 African countries, and generated whole-genome sequences from 12 Late Iron Age individuals. The new findings and data of this study will be important to a wide range of disciplines from science and humanities as well as to the medical sector studying human genetic variation and health in African and African-descendant populations.- Citation:The genetic legacy of the expansion of Bantu-speaking peoples in Africa.

description: Here we initiate an investigation of the equational classes of m-symmetric algebras endowed with two tense operators. These varieties is a generalization of tense algebras. Our main interest is the duality theory for these classes of algebras. In order to do this, we require Urquart's duality for Ockham algebras and Goldblatt's duality for bounded distributive lattice with operations. The dualities enable us to describe the lattices of congruences on tense m-symmetric algebras.

description: This project aims to develop a specialized processor that is optimized for power and algorithm efficiency. The optimization would be targeted for a path-planning algorithm for micro- robots such as insect-bots, UAVs (unmanned aerial vehicles) and for nano-medicine. This processor would provide a computation platform that is smaller, lighter and more power efficient than conventional general-purpose processors to allow these micro-bots to reach a high level of intelligence. These micro-bots would then be able to navigate themselves to their destination, and perform simple tasks and data processing. To achieve this goal, the processor was designed using a custom computing architecture implemented in RTL, then synthesized and detailed designed to layouts that are then fabri- cated into a physical processor. The processor design target was to operate at 100kHz, while consuming only tens of microwatts and weighing only milligrams.

description: We present results for transport properties (diffusion and viscosity) using computer simulations. Focus is made on a densified binary sodium disilicate 2SiO$_2$-Na$_2$O (NS2) liquid and on multicomponent magmatic liquids (MORB, basalt). In the NS2 liquid, results show that a certain number of anomalies appear when the system is densified: the usual diffusivity maxima/minima is found for the network-forming ions (Si,O) whereas the sodium atom displays three distinct régimes for diffusion. Some of these features can be correlated with the obtained viscosity anomaly under pressure, the latter being be fairly well reproduced from the simulated diffusion constant. In model magmas (MORB liquid), we find a plateau followed by a continuous increase of the viscosity with pressure. Finally, having computed both diffusion and viscosity independently, we can discuss the validity of the Eyring equation for viscosity which relates diffusion and viscosity. It is shown that it can be considered as valid in melts with a high viscosity. On the overall, these results highlight the difficulty of establishing a firm relationship between dynamics, structure and thermodynamics in complex liquids.

description: We present the results of full new calculation of radiocarbon 14C production in the Earth atmosphere, using a numerical Monte-Carlo model. We provide, for the first time, a tabulated 14C yield function for the energy of primary cosmic ray particles ranging from 0.1 to 1000 GeV/nucleon. We have calculated the global production rate of 14C, which is 1.64 and 1.88 atoms/cm2/s for the modern time and for the pre-industrial epoch, respectively. This is close to the values obtained from the carbon cycle reservoir inventory. We argue that earlier models overestimated the global 14C production rate because of outdated spectra of cosmic ray heavier nuclei. The mean contribution of solar energetic particles to the global 14C is calculated as about 0.25% for the modern epoch. Our model provides a new tool to calculate the 14C production in the Earth's atmosphere, which can be applied, e.g., to reconstructions of solar activity in the past.

Entamoeba histolytica-induced Activation of the NLRP3 Inflammasome

description: The focus of my research has been the molecular activation and regulation of the NLRP3 inflammasome. The NLRP3 inflammasome is an intracellular innate immune sensor that promotes highly inflammatory responses during infection and tissue injury. NLRP3 belongs to a family of intracellular innate immune sensors that activate a proteolyic cascade driven by caspase-1, which leads to processing and release of interleukin (IL)-1β, IL-18 as well as several other pro-inflammatory cytokines and often triggers a form of lytic cell death known as pyroptosis. My studies address two questions: 1) how the invasive protozoan pathogen Entamoeba histolytica, the disease-causing agent of amebiasis, activates the NLRP3 inflammasome and 2) how prostaglandin E2 (PGE2) rapidly switches-off the NLRP3 inflammasome. Amebiasis is among the three top causes of death from parasitic infections worldwide, as a result of amebic colitis (dysentery) and liver or brain abscess. When E. histolytica invades the intestinal barrier and contacts host tissue there is a profound inflammatory response, which is thought to drive the disease. One of the central outstanding questions has been how the immune response is escalated at sites of invasion. Adherence of the parasite to host cells has long been appreciated in the pathogenesis of amebiasis, but was never considered as a “cue” that host cells use to detect E. histolytica and initiate host defense. We introduce the idea and demonstrate that an intercellular junction forms between E. histolytica and host cells upon contact that engages the NLRP3 inflammasome. For NLRP3 to be effective during an inflammatory response it must be tightly regulated once it has become active. By setting limits on the magnitude and duration of pro-inflammatory signaling the degree of by-stander damage generated during inflammation is reduced and enables the acute inflammatory response to ii progress into a stage of resolution, repair and eventual termination. Prostaglandin E2 (PGE2) is one of the major lipid mediators produced at sites of inflammation that balances and regulates the progression of inflammatory responses. We identified PGE2 signaling via EP4 receptor-cAMP-PKA pathway is a molecular switch that inhibits assembly and activation of the NLRP3 inflammasome.

description: Due to changes in the Earth’s climate, the Earth has experienced colder periods, which generated the growth of continental ice sheets at higher latitudes. The build up of an ice sheet induces flexural stresses in the lithosphere and mantle affecting the stability of pre-existing faults. During and after the end of deglaciation, these faults are activated and the flexural stresses are released as earthquakes. The last ice sheet in North America started to melt 20ka ago, and was gone by 6ka. Here, (re-)activated faults were found, which show vertical fault scarps of up to 100m. As moderate seismicity is observed in North America now, it is of major societal and economic importance to investigate the relationship of this activity to the ongoing rebound. The extended seismological network in northeastern Canada gives us the possibility to analyze local seismicity in more detail than previously possible. Thrust-faulting mechanisms are estimated for five moderate earthquakes that occurred in northern Hudson Bay, and the related stress is NW-SE directed. Comparing this stress direction to results from rebound models and the general background stress field with NE-SW directions, a large difference is found, which might be due to a local fault zone disturbing the main stress field. This study presents an improved two-dimensional rebound model including a fault, which is able to move in a stress field consisting of rebound stress, and horizontal and vertical background stresses. The sensitivity of this fault is tested regarding lithospheric and crustal thickness, viscosity structure of upper and lower mantle, ice-sheet thickness and width, and fault parameters including coefficient of friction, depth, angle and location. Fault throws of up to 64m are obtained using a fault of 30° dipping below the ice-sheet centre. Thicknesses of the crust and lithosphere are two of the major parameters affecting the total fault throw. The ice-sheet width has an impact on the activation time. Even steep-angle faults can be activated. Most faults start to move close to the end of deglaciation, and movement stops after one thrusting/reverse earthquake. However, certain conditions may also lead to several fault movements after the end of glaciation.

Quantifying snowmelt inputs in an alpine watershed for the purpose of investigating the role of groundwater storage

description: Mountain headwaters contribute a greater amount of water to streamflow in Western Canada, relative to their area than lowland areas. Despite this, there is poor understanding of the source water contributions to late summer streamflow and how streamflow may be affected by increases in temperature and changes in precipitation patterns. This study used a water balance approach to study the sources of late summer streamflow and quantify groundwater storage in the Opabin watershed, a high alpine site within Yoho National Park, British Columbia, Canada. Field observations input into the water balance included stream discharge measurements, snow depth and density data, spatially distributed precipitation and on-site meteorological data. Snowmelt contributions to the water balance were quantified using a spatially distributed energy balance model (Utah Energy Balance Model). Spatially distributed incoming shortwave radiation was modeled using ArcGIS Solar Analyst. End-of-winter snow accumulation was quantified using a combination of interpolated field measurements and SWE reconstruction. The snowmelt modeling portion of this study included an assessment of the dominant controls on spatial melt rates in this watershed. Incoming has a greater influence than spatially variable SWE in controlling melt rates in this watershed, and this is attributed to the large gradients in incoming solar radiation. The water balance for two years indicates that annual groundwater storage in the watershed was 8-10% of the annual water balance. However, groundwater contributions during August and September were a substantial component of streamflow, as ascertained by a greater proportion of discharge relative to hydrologic inputs during those months. Linear reservoir modeling results and analysis of the time of concentration indicate that the response time during peak flows is on the order of several days. Response time during late summer and fall is approximately 14 days, as quantified using master recession curve analyses. This work contributes to the understanding of the relative contributions of hydrologic input sources to late summer streamflow in alpine regions.

description: A new method, 'Configurationally-Resolved-Super-Transition-Arrays', for calculation of the spectral absorption coefficient in hot plasmas is presented. In the new method, the spectrum of each Super-Transition-Array is evaluated as the Fourier transform of a single Complex Pseudo Partition Function, which represents the exact analytical sum of the contributions of all constituting unresolved transition arrays sharing the same set of one-electron solutions. Thus, in the new method, the spectrum of each Super-Transition-Array is resolved down to the level of the (unresolved) transition arrays. It is shown that the corresponding spectrum, evaluated by the traditional Super-Transition-Arrays (STA) method [A. Bar Shalom, J. Oreg, W.H. Goldstein, D. Shvarts and A. Zigler, Phys. Rev. A 40, 3183 (1989)], is just the coarse grained Gaussian approximation of the Configurationally-Resolved-Super-Transition-Array. A new computer program is presented, capable of evaluating the absorption coefficient by both the new configurationally resolved and the traditional Gaussian Super-Transition-Arrays methods. A numerical example of gold at temperature 1keV and density 0.5 gr/cm^{3}, is presented, demonstrating the simplicity, efficiency and accuracy of the new method.

description: The epidemic threshold of a social system is the ratio of infection and recovery rate above which a disease spreading in it becomes an epidemic. In the absence of pharmaceutical interventions (i.e. vaccines), the only way to control a given disease is to move this threshold by non-pharmaceutical interventions like social distancing, past the epidemic threshold corresponding to the disease, thereby tipping the system from epidemic into a non-epidemic regime. Modeling the disease as a spreading process on a social graph, social distancing can be modeled by removing some of the graphs links. It has been conjectured that the largest eigenvalue of the adjacency matrix of the resulting graph corresponds to the systems epidemic threshold. Here we use a Markov chain Monte Carlo (MCMC) method to study those link removals that do well at reducing the largest eigenvalue of the adjacency matrix. The MCMC method generates samples from the relative canonical network ensemble with a defined expectation value of λmax. We call this the “well-controlling network ensemble” (WCNE) and compare its structure to randomly thinned networks with the same link density. We observe that networks in the WCNE tend to be more homogeneous in the degree distribution and use this insight to define two ad-hoc removal strategies, which also substantially reduce the largest eigenvalue. A targeted removal of 80% of links can be as effective as a random removal of 90%, leaving individuals with twice as many contacts. Finally, by simulating epidemic spreading via either an SIS or an SIR model on network ensembles created with different link removal strategies (random, WCNE, or degree-homogenizing), we show that tipping from an epidemic to a non-epidemic state happens at a larger critical ratio between infection rate and recovery rate for WCNE and degree-homogenized networks than for those obtained by random removals.

description: Canada’s heavy oil and oil sands resources are majorly exploited using SAGD (Steam-Assisted Gravity Drainage) and CSS (Cyclic Steam Stimulation). Its huge market opportunities may lead to exploitation of unconventional resources currently without booked reserves like the shallow unconfined top water resources. Managing water flow from aquifer, excessive heat losses and possible pollution are the challenges of producing this resource therefore Innovative, responsible and economic methods must be used. SAGD holds a potential for its exploitation since it can be operated at lower pressures although this may lower bitumen production rates because of higher bitumen viscosity. This research examines the impact of top water on SAGD in a reservoir simulation study of limited and unlimited top water models. Results show how steam injection pressures and composition of co-injected fluids affect the behavior of the steam chamber and SAGD performance. Also a clear view as to how mobility and location of fluid phases control the dynamics of SAGD is presented.

description: Let L be a holomorphic line bundle with a positively curved singular Hermitian metric over a complex manifold X. One can define naturally the sequence of Fubini-Study currents associated to the space of square integrable holomorphic sections of the p-th tensor powers of L. Assuming that the singular set of the metric is contained in a compact analytic subset of X and that the logarithm of the Bergman kernel function associated to the p-th tensor power of L (defined outside the singular set) grows like o(p) as p tends to infinity, we prove the following: 1) the k-th power of the Fubini-Study currents converge weakly on the whole X to the k-th power of the curvature current of L. 2) the expectations of the common zeros of a random k-tuple of square integrable holomorphic sections converge weakly in the sense of currents to to the k-th power of the curvature current of L. Here k is so that the codimension of the singular set of the metric is greater or equal as k. Our weak asymptotic condition on the Bergman kernel function is known to hold in many cases, as it is a consequence of its asymptotic expansion. We also prove it here in a quite general setting. We then show that many important geometric situations (singular metrics on big line bundles, Kaehler-Einstein metrics on Zariski-open sets, artihmetic quotients) fit into our framework.

description: In the past decades, human activities caused global Earth system changes, e.g., climate change or biodiversity loss. Simultaneously, these associated impacts have increased environmental awareness within societies across the globe, thereby leading to dynamical feedbacks between the social and natural Earth system. Contemporary modelling attempts of Earth system dynamics rarely incorporate such co-evolutions and interactions are mostly studied unidirectionally through direct or remembered past impacts. Acknowledging that societies have the additional capability for foresight, this work proposes a conceptual feedback model of socio-ecological co-evolution with the specific construct of anticipation acting as a mediator between the social and natural system. Our model reproduces results from previous sociological threshold models with bistability if one assumes a static environment. Once the environment changes in response to societal behaviour, the system instead converges towards a globally stable, but not necessarily desired, attractor. Ultimately, we show that anticipation of future ecological states then leads to metastability of the system where desired states can persist for a long time. We thereby demonstrate that foresight and anticipation form an important mechanism which, once its time horizon becomes large enough, fosters social tipping towards behaviour that can stabilise the environment and prevents potential socio-ecological collapse.

description: The high concentrations of organic and inorganic impurities from the blowdown water of the Steam Assisted Gravity Drainage (SAGD) process in the oilsands operations cause significant operational and environmental issues. In this study the actual SAGD boiler and evaporator blowdown was investigated and found to contain complex mixtures of TSS, TOC and TDS. Further investigations were focused on SAGD boiler blowdown (BBD) water and included the screening of seven advanced oxidation processes (AOPs) which resulted in the selection of three O3/UV, H2O2/UV and O3/H2O2/UV AOP’s for testing TOC degradation in each sequence of the HCl-acidified, CaO-alkalized, CO2-neutralized and original BBD waters. O3/H2O2/UV irradiation showed effective degradation in the neutralized, alkalized, acidified and original BBD at 70%, 68.3%, 55.6% and 9.4% TOC removal. An unique, semi-batch treatment system was designed, integrated and evaluated using HCl-acidified, CaO-alkalized, CO2-neutralized BBD water in three stages; (1) Stage A; precipitation and centrifugation for TSS and TOC removal, (2) Stage B; O3/H2O2/UV for TOC degradation, and (3) Stage C; reverse osmosis filtration for the TDS and residual TOC removal. Stage A results showed that the HCl-acidified BBD at pH 4.2 achieved the highest TOC removal by 44.7% and TSS by 98.5% likely because the net reduction in the molecular electrical repulsion and neutralization of acid groups led to their aggregation and removal. Stage B results showed that the O3/H2O2/UV achieved the highest TOC removal of 68.0% in the CO2-neutralized BBD likely because interferences of the competing inorganic carbonate and bicarbonate species that scavenge hydroxyl radicals were minimized. Stage C results showed that reverse osmosis filtration purified all samples, but achieved the highest removal of 99.7% residual TOC and 98.8% TDS in the HCl-acidified BBD and the highest permeate recovery at 40.5% in the alkalized and neutralized BBD. Since there is a lack of published information on SAGD blowdown the result of this study is significant and a precursor to advancing future research solutions.

description: Anomalous flux ratios between quasar images are suspected to be caused by substructures in lens galaxies. We present new deep and high resolution H and Ks imaging of the strongly lensed quasar SDSS J0924+0219 obtained using the ESO VLT with adaptive optics and the Laser Guide Star system. SDSS J0924+0219 is particularly interesting as the observed flux ratio between the quasar images vastly disagree with the predictions from smooth mass models. With our adaptive optics observations we find a luminous object, Object L, located ~0.3" to the North of the lens galaxy, but we show that it can not be responsible for the anomalous flux ratios. Object L as well as a luminous extension of the lens galaxy to the South are seen in the archival HST/ACS image in the F814W filter. This suggests that Object L is part of a bar in the lens galaxy, as also supported by the presence of a significant disk component in the light profile of the lens galaxy. Finally, we do not find evidence for any other luminous substructure that may explain the quasar images flux ratios. However, owe to the persistence of the flux ratio anomaly over time (~ 7 years) a combination of microlensing and milli-lensing is the favorite explanation for the observations.

Deep England

description: Deep England as an icon arose during the Second World War as a unifying concept of everything English. This icon has, however, long historical roots, and its significance is not only patriotic, but it is also a reaction to modernity. The icon is materialized in a fictitious southern, rural and pastoral England with close-knit communities centred on the village green. A number of samples will be analysed to identify the cultural meaning of the icon in the light of the theories of Svetlana Boym (nostalgia), Marc Augé (places), Angus Calder (cultural history) and Paul Kingsnorth (sociology). Based on analyses of these samples the article finally suggests a cultural, semiotic definition of icons.
 The samples are:
 • Rupert Brooke: “The Old Vicarage, Grantchester”, 1912
 • Humphrey Jennings: The Farm, 1938, English Harvest, 1939 andSpring Offensive, 1940
 • Terence Cuneo: “BRITAIN in WINTER”, 1948
 • J.R.R. Tolkien: “The Scouring of the Shire” from The Lord of theRings, 1939-1949
 • Agatha Christie: The Mirror Crack’d from Side to Side, 1962

description: Background: Depression or anxiety are under-diagnosed and under-treated in those with dementia or Parkinson’s disease (PD). Objectives: The objectives of this thesis were to first understand what high quality guideline recommendations exist for depression or anxiety in dementia or PD. Secondly to explore the barriers and facilitators to implementing these guidelines. Methods: A systematic review of guidelines was completed, following the PRISMA statement and using the AGREE II tool to assess quality. In focus groups with stakeholders, we assessed the barriers and facilitators to guideline use and implementation. Results: Guideline quality scores were lowest for stakeholder involvement, applicability, and editorial independence. Major barriers to use included a lack of evidence, lack of applicability to the practice population, impractical or out of date recommendations. Conclusions: There are guideline recommendations for depression or anxiety in dementia and PD. However, practitioners have difficulty with implementation due to a lack of evidence and applicability.
