description: In this work, laboratory tests with live bivalves as well as the conceptual design of additively manufactured surrogate models are presented. The overall task of this work is to develop a surrogate best fitting to the live mussels tested in accordance to the identified surface descriptor, i.e., the Abbott-Firestone Curve, and to the hydrodynamic behaviour by means of drag and inertia coefficients. To date, very few investigations have focused on loads from currents as well as waves. Therefore, tests with a towing carriage were carried out in a wave flume. A custom-made rack using mounting clamps was built to facilitate carriage-run tests with minimal delays. Blue mussels (Mytilus edulis) extracted from a site in Germany, which were kept in aerated seawater to ensure their survival for the test duration, were used. A set of preliminary results showed drag and inertia coefficients C D and C M ranging from 1.16-3.03 and 0.25 to 1.25. To derive geometrical models of the mussel dropper lines, 3-D point clouds were prepared by means of 3-D laser scanning to obtain a realistic surface model. Centered on the 3-D point cloud, a suitable descriptor for the mass distribution over the surface was identified and three 3-D printed surrogates of the blue mussel were developed for further testing. These were evaluated regarding their fit to the original 3-D point cloud of the live blue mussels via the chosen surface descriptor. © 2019 by the authors.
title: An investigation into nutritional aspects of care in long stay establishments for elderly people

Subjects: subject: Nutrition, health care management, gerontology, Aging.

description: Demographic projections indicate that there will be an increase in the number of elderly people over the next century. This has major implications for the caring sector as requirements for care increase with age. Nutrition has a vital role in the maintenance of health and quality of life. However, nutritional care may have a low priority in some long-term care settings. A higher than expected prevalence of low body weight and inadequate dietary intake in long-term care has raised concern due to the morbidity and mortality associated with it. This study aimed to examine the nutritional status of elderly NHS continuing care residents, assess the nutritional adequacy of the diet offered and consumed and examine the environment where they ate. The information collected suggests that similar anthropometric trends appear to exist between elderly groups in different geographical areas such as decreasing weight and body mass with age but, absolute values differ. This suggests that the reference data available may be inappropriate. The study group appeared leaner and more muscular than the reference. The prevalence of nutritional status varied from 11-24% depending on the criteria used. This prevalence appears high compared to free living elderly and either similar or lower than other elderly long-term care groups. The lack of a gold standard definition for undernutrition and appropriate reference percentiles has important implications for screening and identifying undernutrition. Energy consumed was inadequate compared to the EAR and ETEE, this may explain the prevalence of undernutrition and the inadequate nutrient content of the diet. Intakes may have been influenced by various social and environmental factors, which may have placed the group at nutritional risk. Conclusion The group seem at risk of undernutrition from lack of nutritional screening, inadequate diet and various environmental factors. The group was leaner but more muscular than community reference groups and the prevalence of undernutrition was higher than community free-living elderly. Further research is required on appropriate reference percentiles, criteria for identifying undernutrition and environmental risk factors. Recommendations Various recommendations were made to the Health Board and Trust Management Teams which required multi-disciplinary input and change in aspects of nutritional care. Recommendations included: redesigning menus making them more appropriate for the elderly (both nutritionally and culinary); implementation of nutritional screening; nutritional education of ward staff; vitamin D supplementation; environmental improvements; identifying, recording and taking account of residents' meal, snack and drink preferences.

description: The aim of the present thesis was the study of the narrative of the Russian World both as a means of soft power of Russia directed mainly towards the Near Abroad, and as a means of legitimizing Russian foreign policy in Russian public opinion.We examined the content given by the Russian political leadership to the concepts of «Compatriot» and «Near Abroad» and analyzed Russia’s soft power channels. We then analyzed the development and content of the narrative of the Russian World and the contribution of the Russian Orthodox Church to its formation. We also studied the interdependence and relations between the Russian State and the Church and referred to the evolution of the Church issue in Ukraine since 2014. Finally, we developed our positions on the Russian-Ukrainian war and the attempt to justify and legitimize it, both by the political and church leadership, through the narrative of the Russian World.

description: Let Omega^3(SU(n)) be the Lie group of based mappings from S^3 to SU(n). We construct a Lie group extension of Omega^3(SU(n)) for n>2 by the abelian group of the affine dual space of SU(n)-connections on S^3. In this article we give several improvement of J. Mickelsson's results in 1987, especially we give a precise description of the extension of those components that are not the identity component,. We also correct several argument about the extension of Omega^3(SU(2)) which seems not to be exact in Mickelsson's work, though his observation about the fact that the extension of Omega^3(SU(2)) reduces to the extension by Z_2 is correct. Then we shall investigate the adjoint representation of the Lie group extension of Omega^3(SU(n)) for n>2.
title: A kind of India happens everywhere : Bombay-London-New York and beyond

Publisher: name: University of Kent
Year: 2022

description: In this thesis I explore the literary reconfigurations of Bombay, London and New York in texts written by South Asian diasporic authors between the middle of the Nineties and the first decade of the new millennium. Situating my argument within Bakhtin’s model of the chronotope, I contend that movement, displacement and relocations contribute to the creation of a renewed concept of space, by means of which the three metropolitan destinations are perceived to coexist in one single location. ‘A kind of India happens everywhere’, asserts the narrator of The Ground Beneath Her Feet (1999). Equating cities to nations, I seek to illustrate this pronouncement through an analysis of South Asian immigration, its impact on the concept of national affiliation alongside the disjunctures it creates within the simulacral continuity projected by the panoptic rhetoric of economic globalisation. I commence by investigating national space and how textuality interrupts the cultural fixities of the nation. The creativity of fiction, de-provincialising traditional syntax through a process of ‘inscription’, generates the ‘elsewhere’ of fictionality. In this space antipodal constructions of national affiliation are displaced and dismantled. It is in this site, forged by literature, which I also term the ‘Beyond’, that Bombay, London and New York find their referents. Combining the abstractions of theory with the necessity to provide an alternative insight into the study of multidirectional travel between North and South, I investigate the trajectories described by South Asian diasporic subjectivities in a diachronic perspective. From post-war immigration to Britain, I proceed to illustrate the new destinations of South Asian relocations. Arguing that in recent texts London is presented as a transit zone for New York, I discuss neo diasporic formations in the US, and focus on the notion of deterritorialisation propagated by the media. I subsequently present an opposite view of migration in a diptych chapter in which I reveal that recent South Asian texts tend to expose the gaps rather than the continuity between cities. I conclude that the writing of later authors exhibits a magnification of the disjunctures exacerbated by displacement.

description: A statistical analysis of radial distributions of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey (SDSS DR7) catalogue within an interval $0.16 \leq z \leq 0.47$ is carried out. We found that the radial distribution of $\sim$ 106,000 LRGs incorporates a few quasi-periodical components relatively to a variable $η$, dimensionless line-of-sight comoving distance calculated for the $Λ$CDM cosmological model. The most significant peaks of the power spectra are obtained for two close periodicities corresponding to the spatial comoving scales $(135 \pm 12) h^{-1}$ Mpc and $(101 \pm 6)h^{-1}$ Mpc. The latter one is dominant and consistent with the characteristic scale of the baryon acoustic oscillations. We analyse also the radial distributions of two other selected LRG samples: $\sim$ 33,400 bright LRGs ($-23.2 < M \leq -21.8$) and $\sim$ 60,300 all LRGs within a rectangle region on the sky, and show differences of the quasi-periodical features characteristic for different samples. Being confirmed the results would allow to give preference of the spatial against temporal models which could explain the quasi-periodicities discussed here. As a caveat we show that estimations of the significance levels of the peaks strongly depend on a smoothed radial function (trend) as well as characteristics of random fluctuations.

description: Flood peaks and volumes are essential design variables and can be simulated by precipitation–runoff (P–R) modelling. The high-resolution precipitation time series that are often required for this purpose can be generated by various temporal disaggregation methods. Here, we compare a simple method (M1, one parameter), focusing on the effective precipitation duration for flood simulations, with a multiplicative cascade model (M2, 32/36 parameters). While M2 aims at generating realistic characteristics of precipitation time series, M1 aims only at accurately reproducing flood variables by P–R modelling. Both disaggregation methods were tested on precipitation time series of nine Swiss mesoscale catchments. The generated high-resolution time series served as input for P–R modelling using a lumped HBV model. The results indicate that differences identified in precipitation characteristics of disaggregated time series vanish when introduced into the lumped hydrological model. Moreover, flood peaks were more sensitive than flood volumes to the choice of disaggregation method. © 2019, © 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.

description: This paper shows that the problem of web services representation is crucial and analyzes the various factors that influence on it. It presents the traditional representation of web services considering traditional textual descriptions based on the information contained in WSDL files. Unfortunately, textual web services descriptions are dirty and need significant cleaning to keep only useful information. To deal with this problem, we introduce rules based text tagging method, which allows filtering web service description to keep only significant information. A new representation based on such filtered data is then introduced. Many web services have empty descriptions. Also, we consider web services representations based on the WSDL file structure (types, attributes, etc.). Alternatively, we introduce a new representation called symbolic reputation, which is computed from relationships between web services. The impact of the use of these representations on web service discovery and recommendation is studied and discussed in the experimentation using real world web services.

description: Purpose - The recent COVID-19 pandemic affects all segments of the population in all possible fields of life. To encounter this critical situation and to safeguard the health of the library users & library staff, the library services have been forced to adapt and accept the “new normal” and give a greater use and reliance on virtual space than ever before with physical spaces. This paper aims to demonstrate an artificial intelligence (AI)-driven solution that can be practically implemented in the form of a “InfoBot” or “Chatbot” to fulfil user needs 24/7 with minimal or without human intervention.
 Design/methodology/approach - To give a general overview of the use of AI Chatbot in libraries and its multitasking features followed by the practical implementation, a versatile AIchatbot service, Engati is used as a target bot with its basic free plan.
 Findings - The study findings reveal that AI Chatbots offer a dependable solution for the libraries to initiate virtual assistance, thus augmenting the reference service while adding a newer dimension to virtual reference service.
 Social implications - Innovative and intelligent information service would be overcoming the time and location barriers reaffirming the concept of “library without walls” while falling in line with the five laws of library science as propounded by Dr S.R. Ranganathan, the father of library science in India.
 Originality/value - Though the implementation of bots and chatbots is not a purely novel concept to explore, no such research has been conducted focusing particularly on its exceptional benefits in the library in reference to the recent pandemic.
title: A study of the impact of psychodynamic counselling on disease activity in early rheumatoid arthritis

Subjects: subject: Counseling, psychology, physiological psychology.

description: Title A study of the impact of psychodynamic counselling on disease activity in early rheumatoid arthritis. Design; Prospective randomised controlled trial. Setting: Physiotherapy Department, Glasgow Royal Infirmary. Subjects: 22 female patients with disease duration of less than three years. Intervention: Individual counselling on a weekly basis of up to ten weeks, each session lasting fifty minutes. Control group received five early education talks on the subject of rheumatoid arthritis from various health professionals, each session lasting ninety minutes. Methods: Patients randomly allocated into either a counselling group (group1: n=13) or an education group (group 2 ; n=9). Every patient was assessed during the ten week period at Week 0, 5, and 10. Disease activity was measured using the modified disease activity score (DAS) based on the Eular Core Data Set. The Disease Activity Score is a combined index used to assess disease activity in Rheumatoid Arthritis. A change of 1.08. is assumed to signify a significant improvement or deterioration. (Appendix 2). Main Results There was no significant difference between the groups at baseline and no significant difference was found in disease activity between the groups. In terms of changes over the ten weeks there was a trend towards improvement in the counselled group for the following subjective variables:- early morning stiffness, number of swollen joints, number of tender joints and pain as reported on a visual analogue scale. Quality of life was measured using the Arthritis Impact Score 2 (AIMS2), Hospital Anxiety and Depression Score (HAD) and the Health Assessment Questionnaire (HAQ). No statistical significance was found between the groups for any of the quality of life measures. Conclusions This limited pilot study suggests that psychodynamic counselling over a ten week period does not provide a significantly large improvement in ameliorating disease activity when compared to early education talks. There is however a suggestion of a moderate effect in the counselled group. Implications for The NHS It is difficult to make any definitive statement about the implications of the study for the NHS. Counselling may need to be made available to patients at times when they perceive there to be a need. The brief nature of the intervention may also be a factor to be considered, with each individual having different requirements with respect to the numbers of sessions offered. The fact that individuals self-select when considering counselling, needs to be taken into account when carrying out a randomised trial. This study does, however, highlight the importance of the doctor-patient relationship in terms of helping the patient to deal with the on-going difficulties of negotiating the independent and dependent self.

description: Silicon-based sensors are widely used for monitoring solar irradiance, in particular, in the field of Photovoltaic (PV) applications. We present a method to correct the global horizontal irradiance measured by silicon-based sensors that reduces the difference to the standard thermopile sensor measurements. A major motivation to use silicon-based sensors for the measurements of irradiance is their lower cost. In addition, their response time is much lower, and their spectral response is much closer to that of the PV systems. The analysis of the differences is based on evaluating four parameters that influence the sensor measurements, namely the temperature, cosine error, spectral mismatch, and calibration factor. Based on the analysis, a correction model is applied to the silicon sensors measurements. The model separates measurements under a clear sky and cloudy sky by combining the clearness index and the solar zenith angle. By applying the correction model on the measurements of the silicon-based sensor, the differences between sensor readings have been reduced significantly. The relative root mean squared difference (rRMSD) between the daily solar irradiation measured by both sensors decreased from 10.6% to 5.4% after applying the correction model, while relative mean absolute difference (rMAD) decreased from 7.4% to 2.5%. The difference in total annual irradiation decreased from 70 KWh/m2 (6.5%) to 15 kWh/m2 (1.5%) by the correction. The presented correction method shows promising results for a further improvement in the accuracy of silicon-based sensors.

description: In this study, the wave-induced distribution of 13 microplastic (MP) samples of different size, shape, and density was investigated in a wave flume with a sandy mobile beach bed profile. The particle parameter were chosen based on an occurrence probability investigated from the field. MP abundances were analyzed in cross-shore and vertical direction of the test area after over 40,000 regular waves. It was found, that MP particles accumulated in more shallow waters with increasing size and density. Particles with high density (ρs>1.25 g/cm3) have been partly confined into deeper layers of the sloping beach during the formation of the bed profile. Particles with a density lower than that of water used in the experiments floated constantly in the surf zone or deposited on the beach caused by wave run-up. A correlation was found between the settling velocity of the MP particles and the flow velocity at the accumulation point and a power function equation developed. The obtained results were critically discussed with findings from the field and further laboratory studies.

description: We present detailed chemical abundances for the bright carbon-enhanced metal-poor (CEMP) star BD+44 493, previously reported on by Ito et al. Our measurements confirm that BD+44 493 is an extremely metal-poor ([Fe/H]=-3.8) subgiant star with excesses of carbon and oxygen. No significant excesses are found for nitrogen and neutron-capture elements (the latter of which place it in the CEMP-no class of stars). Other elements that we measure exhibit abundance patterns that are typical for non-CEMP extremely metal-poor stars. No evidence for variations of radial velocity have been found for this star. These results strongly suggest that the carbon enhancement in BD+44 493 is unlikely to have been produced by a companion asymptotic giant-branch star and transferred to the presently observed star, nor by pollution of its natal molecular cloud by rapidly-rotating, massive, mega metal-poor ([Fe/H] < -6.0) stars. A more likely possibility is that this star formed from gas polluted by the elements produced in a "faint" supernova, which underwent mixing and fallback, and only ejected small amounts of elements of metals beyond the lighter elements. The Li abundance of BD+44 493 (A(Li)=log(Li/H)+12=1.0) is lower than the Spite plateau value, as found in other metal-poor subgiants. The upper limit on Be abundance (A(Be)=log(Be/H)+12

description: Since 1969, Lunar Laser Ranging (LLR) data have been collected by various observa-tories and analysed by different analysis groups. In the recent years, observations with bigger telescopes (APOLLO) and at infra-red wavelength (OCA) are carried out, resulting in a better distribution of precise LLR data over the lunar orbit and the observed retro-reflectors on the Moon. This is a great advantage for various investigations in the LLR analysis. The aim of this study is to evaluate the benefit of the new LLR data for the determination of relativistic parame-ters. Here, we show current results for relativistic parameters like a possible temporal variation of the gravitational constant Ġ/G0 = (−5.0 ± 9.6) × 10−15 yr−1, the equivalence principle with ∆( mg /mi)EM= (−2.1±2.4)×10−14, and the PPN parameters β − 1 = (6.2 ± 7.2) × 10−5 and γ − 1 = (1.7 ± 1.6) × 10−4. The results show a significant improvement in the accuracy of the various parameters, mainly due to better coverage of the lunar orbit, better distribution of measurements over the lunar retro-reflectors, and last but not least, higher accuracy of the data. Within the estimated accuracies, no violation of Einstein’s theory is found and the results set improved limits for the different effects. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

description: This study explores the projected responses of tidal dynamics in the North Sea induced by the interplay between plausible projections of sea-level rise (SLR) and morphological changes in the Wadden Sea. This is done in order to gain insight into the casual relationships between physical drivers and hydro-morphodynamic processes. To achieve this goal, a hydronumerical model of the northwest European shelf seas (NWES) was set-up and validated. By implementing a plausible set of projections for global SLR (SLRRCP8.5 of 0.8 m and SLRhigh−end of 2.0 m) by the end of this century and beyond, the model was run to assess the responses of the regional tidal dynamics. In addition, for each considered SLR, various projections for cumulative rates of vertical accretion were applied to the intertidal flats in the Wadden Sea (ranging from 0 to 100% of projected SLR). Independent of the rate of vertical accretion, the spatial pattern of M2 amplitude changes remains relatively stable throughout most of the model domain for a SLR of 0.8 m. However, the model shows a substantial sensitivity toward the different rates of vertical accretion along the coasts of the Wadden Sea, but also in remote regions like the Skagerrak. If no vertical accretion is assumed in the intertidal flats of the Wadden Sea, the German Bight and the Danish west coast are subject to decreases in M2 amplitudes. In contrast, those regions experience increases in M2 amplitudes if the local intertidal flats are able to keep up with the projected SLR of 0.8 m. Between the different scenarios, the North Frisian Wadden Sea shows the largest differences in M2 amplitudes, locally varying by up to 14 cm. For a SLR of 2.0 m, the M2 amplitude changes are even more amplified. Again, the differences between the various rates of vertical accretion are largest in the North Frisian Wadden Sea (> 20 cm). The local distortion of the tidal wave is also significantly different between the scenarios. In the case of no vertical accretion, tidal asymmetry in the German estuaries increases, leading to a potentially enhanced sediment import. The presented results have strong implications for local coastal protection strategies and navigation in adjacent estuaries. © Copyright © 2021 Jordan, Visscher and Schlurmann.

description: Likelihood based-learning of graphical models faces challenges of computational-complexity and robustness to model mis-specification. This paper studies methods that fit parameters directly to maximize a measure of the accuracy of predicted marginals, taking into account both model and inference approximations at training time. Experiments on imaging problems suggest marginalization-based learning performs better than likelihood-based approximations on difficult problems where the model being fit is approximate in nature.

title: A randomised controlled trial of home based occupational therapy for stroke patients

Subjects: subject: Occupational therapy, physical therapy.

description: Discharge home would appear to be a critical stage in stroke rehabilitation with patients experiencing poor co-ordination of discharge planning, psychosocial problems and reduced quality of life. This study used a randomised controlled trial to evaluate the effectiveness of a short post-discharge home-based occupational therapy service on the recovery of stroke patients discharged home from hospital. The home based intervention programme was designed using focus group discussions to determine the views of patients and local therapists. One hundred and thirty eight patients were randomly allocated to either a conventional outpatient follow-up or conventional services plus six weeks of home based occupational therapy intervention. All patients were assessed before discharge, at seven weeks and six months to measure functional ability, quality of life, and perception of outcome and experience of discharge. Information was also obtained on readmission rates, strain on carers and resources used to operate the home based service. At seven weeks the intervention group showed significant (p<0.05) benefits in terms of improvement in self-care, extended activities of daily living, and satisfaction with their performance. The intervention group also reported improved subjective health experience on the emotion score of the COOP charts and in work/leisure on the London Handicap Scale. Patients receiving home-based occupational therapy were significantly less likely to deteriorate (death or increased disability) and were significantly more likely to continue therapy at home and to have received additional aids/equipment. No significant differences were observed in carer outcome between the two groups. By six months the treatment group were still reporting significant improvements in self-care and a trend towards treatment patients achieving higher functional scores was apparent but not statistically significant. No differences were observed in subjective health experience. However intervention patients were more satisfied with the preparations made for them to return home, with the stroke information they received and who to contact for further advise. The study concluded that a brief occupational therapy service carried out in the patient's home immediately after discharge can provide a continuity of care between hospital and the community and improve the functional outcome and satisfaction of stroke patients. The effects of the intervention were diluted over time and did not appear to influence the subjective health experience of patients or carers.

description: Subject of this paper is the weak lensing effect on galaxies that show intrinsically correlated ellipticities. In our model, we investigate the distortion of the ellipticity field if the galaxies experience an apparent shift in their position by weak lensing deflection and compare this effect to the shearing effect induced by tidal fields. Starting with a derivation of intrinsic ellipticity spectra by employing a tidal torquing model generating galactic angular momenta, we model the galaxy ellipticity by assuming that the galactic disk forms perpendicularly to the host halo angular momentum direction and derive intrinsic ellipticity E-mode and B-mode spectra from the angular momentum statistics. The lensing effect on the ellipticity field is modeled by employing the methodology developed in the framework of lensing of the cosmic microwave background polarisation. For EUCLID, ellipticity correlations are altered by lensing deflection on multipoles l>1000 by ~5% for the ellipticity E-modes and by ~30% for the B-modes, while a shallower survey would exhibit larger changes on larger angular scales. In addition to the convolving effect of lensing on the ellipticity spectra we investigate the E/B-mode conversion, and discuss the possibility of measuring correlations between different multipoles which is evoked by the homogeneity breaking effect of the lensing displacement. Our conclusion is that although shape correlations generated by weak gravitational shear is dominant, the shifting effect due to lensing is shaping the ellipticity spectra on small angular scales and causes a number of interesting phenomena, which might be observable by future surveys.

description: The citizen science starter kit shares information about what citizen science is (and what citizen science is not) through definitions, guidelines and tips & tricks. Furthermore, it aims to raise awareness about the opportunities of citizen science through providing key examples of citizen science projects. As such, the starter kit also encourages researchers to start with citizen science, and to consider the citizen science approach in (project) proposals. The starter kit also supports reflection and creative thinking. Through the interactive materials, researchers should be able to make critical design choices for running a citizen science research (project). Lastly, it provides you the necessary materials to get started with citizen science. You will find a step-by-step plan with templates and checklists, and other relevant resources to set up the activities.
It consists of 4 modules: 1) Start to learn about citizen science; 2) Determine if citizen science is right for your research; 3) Crucial design factors for successful citizen science 4) Getting started with citizen science
description: Version 3 has been completely updated with additions and new resources, and is expanded with a fourth, interactive module to put theory into practice.

description: Quantum metrology enables new applications in geodesy, including relativistic geodesy. The recent progress in optical atomic clocks and in long-distance frequency transfer by optical fiber together pave the way for using measurements of the gravitational frequency redshift for geodesy. The remote comparison of frequencies generated by calibrated clocks will allow for a purely relativistic determination of differences in gravitational potential and height between stations on Earth surface (chronometric leveling). The long-term perspective is to tie potential and height differences to atomic standards in order to overcome the weaknesses and inhomogeneity of height systems determined by classical spirit leveling. Complementarily, gravity measurements with atom interferometric setups, and satellite gravimetry with space borne laser interferometers allow for new sensitivities in the measurement of the Earth's gravity field.

Quasars Probing Quasars IV: Joint Constraints on the Circumgalactic Medium from Absorption and Emission

description: We have constructed a sample of 29 close projected quasar pairs where the background quasar spectrum reveals absorption from optically thick HI gas associated with the foreground quasar. These unique sightlines allow us to study the quasar circumgalactic medium (CGM) in absorption and emission simultaneously, because the background quasar pinpoints large concentrations of gas where Ly-a emission, resulting from quasar-powered fluorescence, resonant Ly-a scattering, and/or cooling radiation, is expected. A sensitive slit-spectroscopic search (1-sigma limits of SB_Lya ~= 3e-18 erg/s/cm^2/arcsec^2) for diffuse Ly-a emission in the environments of the foreground quasars is conducted. We fail to detect large-scale ~ 100 kpc Ly-a emission, either at the location of the optically thick absorbers or in the foreground quasar halos, in all cases except a single system. We interpret these non-detections as evidence that the gas detected in absorption is shadowed from the quasar UV radiation due to obscuration effects, which are frequently invoked in unified models of AGN. Small-scale R_perp 50 A) Ly-alpha-emitter with luminosity L_Lya =2.1+-0.32e41 erg/s at small impact parameter R_perp=134 kpc from one foreground quasar, and argue that it is more likely to result from quasar-powered fluorescence, than simply be a star-forming galaxy clustered around the quasar. Our observations imply that much deeper integrations with upcoming integral-field spectrometers such as MUSE and KCWI will be able to routinely detect a diffuse Ly-a glow around bright quasars on scales R ~ 100 kpc and thus directly image the CGM.
