description: Aims. The H-alpha emission of solar flare kernels and associated hard X-ray (HXR) emission often show similar time variations but their light curves are shifted in time by energy transfer mechanisms. We searched for fast radiative response of the chromosphere in the H-alpha line as a signature of electron beam heating. Methods. We investigate the time differences with sub-second resolution between the H-alpha line emission observed with a Multi-channel Subtractive Double Pass (MSDP) spectrograph on the Large Coronagraph and Horizontal Telescope at Bialkow Observatory, Poland, and HXR emission recorded by the RHESSI spacecraft during several flares, greatly extending our earlier analysis (Paper I) to flares between 2003 and 2005. Results. For 16 H-alpha flaring kernels, observed in 12 solar flares, we made 72 measurements of time delays between local maxima of the RHESSI X-ray and H-alpha emissions. For most kernels, there is an excellent correlation between time variations in the H-alpha line emission (at line centre and in the line wings) and HXR (20-50 keV) flux, with the H-alpha emission following features in the HXR light curves generally by a short time lapse delta t = 1-2 s, sometimes significantly longer (10-18 s). We also found a strong spatial correlation. Conclusions. Owing to our larger number of time measurements than in previous studies, the distribution of delta t values shows a much clearer pattern, with many examples of short (1-2 s) delays of the H-alpha emission, but with some flares showing longer (10-18 s) delays. The former are consistent with energy transfer along the flaring loop legs by non-thermal electron beams, the latter to the passage of conduction fronts.

Habitus, Field Theory and the ‘Bridge’: Using a Bourdieusian Approach to Examine and Explain Cold War Continuities in Britain’s Post-Cold War Foreign Policy

description: This thesis examines the Anglo-American ‘special relationship’ and the ‘bridge’ role the United Kingdom has played within it since 1945, with the British seeing it as an important part of what Tate calls the post-war Anglo-American “hegemonic division of labour.” Playing this ‘bridge’ role made sense given the logic of Cold War bipolarity, but the post-Cold War shift to unipolarity has significantly decreased the need for ‘bridges’ in the international system, yet successive post-Cold War British governments remained committed to playing this role. This paper asks why this occurred and if the British are still playing this role. By applying a Bourdieusian approach the need to examine microstructures when studying British foreign policy is revealed, with the concepts of field theory and habitus highlighting the important role the unique individual experiences and beliefs of the prime minister play in the crafting of British foreign policy.

Hypotheses and tests of an evolved psychological architecture for social norms
Creators: name: Zhao, Wanying
Publisher: name: University of British Columbia
Year: 2010

description: Due to the critical importance of social norms and their ubiquitous presence over the course of human history, culture-gene co-evolutionary processes should have selected for a psychological architecture that supports learning and implementing local norms (Richerson & Henrich, 2009). In this thesis, I follow the above line of reasoning to argue that dealing with social norms presented domain-specific challenges to the cultural learner, requiring specialized cognitive processes to deal specifically with norms. This motivates several predictions about major design features that a psychological architecture evolved to meet those challenges should possess. I present a survey of extant evidence that are consistent with these predictions. Two empirical studies designed to test a number of these predictions are presented.

description: Intermittent transitions, associated with critical dynamics and characterized by power-law distributions, are commonly observed during sleep. These critical behaviors are evident at the microscopic level through neuronal avalanches and at the macroscopic level through transitions between sleep stages. To clarify these empirical observations, models grounded in statistical physics have been proposed. At the mesoscopic level of cortical activity, critical behavior is indicated by the intermittent transitions between various cortical rhythms. For instance, empirical investigations utilizing EEG data from rats have identified intermittent transitions between $δ$ and $θ$ rhythms, with the duration of $θ$ rhythm exhibiting a power-law distribution. However, a dynamic model to account for this phenomenon is currently absent. In this study, we introduce a network of sparsely coupled excitatory and inhibitory populations of quadratic integrate-and-fire (QIF) neurons to demonstrate that intermittent transitions can emerge from the intrinsic fluctuations of a finite-sized system, particularly when the system is positioned near a Hopf bifurcation point, which is a critical point. The resulting power-law distributions and exponents are consistent with empirical observations. Additionally, we illustrate how modifications in network connectivity can affect the power-law exponent by influencing the attractivity and oscillation frequency of the stable limit cycle. Our findings, interpreted through the fundamental dynamics of neuronal networks, provide a plausible mechanism for the generation of intermittent transitions between cortical rhythms, in alignment with the power-law distributions documented in empirical researches.

description: Using atomistic simulations we investigate the morphological properties of graphene deposited on top of a nanostructured substrate. Sinusoidally corrugated surfaces, steps, elongated trenches, one dimensional and cubic barriers, spherical bubbles, Gaussian bump and Gaussian depression are considered as support structures for graphene. The graphene-substrate interaction is governed by van der Waals forces and the profile of the graphene layer is determined by minimizing the energy using molecular dynamics simulations. Based on the obtained optimum configurations, we found that: (i) for graphene placed over sinusoidally corrugated substrates with corrugation wave lengths longer than 2\,nm, the graphene sheet follows the substrate pattern while for supported graphene it is always suspended across the peaks of the substrate, (ii) the conformation of graphene to the substrate topography is enhanced when increasing the energy parameter in the van der Waals model, (iii) the adhesion of graphene into the trenches depends on the width of the trench and on graphene's orientation, i.e. in contrast to a small width (3 nm) nanoribbon with armchair edges, the one with zig-zag edges follows the substrate profile, (iv) atomic scale graphene follows a Gaussian bump substrate but not the substrate with a Gaussian depression, and (v) the adhesion energy due to van der Waals interaction varies in the range [0.1-0.4] J/m^2.

Effect of topical knowledge on L2 writing

description: This study investigates the effect of topical knowledge on university-level ESL (English as a Second Language) students’ writing in a testing situation, following Messick”s (1989) validity theory, which embraces an integration of multiple types of validity evidence (content-, criterion-, and construct-based validity, along with social consequences) to support the inferences drawn from the test scores. A total of 50 participants with different levels of English language proficiency and various ethnic, cultural, and linguistic backgrounds took part in the study in a metropolitan city in western Canada. Each student wrote two 60-minute essays: one responding to a prompt requiring general knowledge and the other responding to a prompt requiring specific prior knowledge. Using a mixed methods sequential explanatory design (Creswell & Plano Clark, 2007), the study collected two types of data to attend to its purposes: (1) quantitative data based on repeated direct measures of the prompt effect on the overall writing scores, component scores (content, organization, and language), and indicator scores (idea quality, position-taking, idea development, idea wrap-up, cohesion, coherence, fluency, accuracy, and lexical complexity); and (2) qualitative interview data for an in-depth understanding of the writers’ perceptions of the two writing prompts. The overall writing scores showed that students, especially those at the intermediate and advanced proficiency levels, performed significantly better on the general topic than they did on the specific topic. The topic-specific task produced lower scores on content, organization, and language due to poor idea quality, hidden position, insufficient idea development, weak idea wrap-up, a lack of coherence and cohesion, shorter length, more syntax and lexical errors, and less frequent use of academic words. Posttest interviews confirmed how participating students were challenged by writing prompt that requires specific prior knowledge. The findings suggest that topical knowledge is a fundamental schemata to elicit a writer’s performance. Without such knowledge, an ESL writer, even with a high English proficiency, cannot achieve his or her optimal performance. The study calls attention to the effect of specific topical knowledge on ESL students’ writing and the importance of developing appropriate prompts for writing tests.

description: We study the probability distribution function (PDF) of the order parameter of the three-dimensional $O(N)$ model at criticality using the functional renormalisation group. For this purpose, we generalize the method introduced in [Balog et al., Phys. Rev. Lett. {\bf 129}, 210602 (2022)] to the $O(N)$ model. We study the large $N$ limit, as well as the cases $N=2$ and $N=3$ at the level of the Local Potential Approximation (LPA), and compare our results to Monte Carlo simulations. We compute the entire family of universal scaling functions, obtained in the limit where the system size $L$ and the correlation length of the infinite system $ξ_\infty$ diverge, with the ratio $ζ=L/ξ_\infty$ constant. We also generalize our results to the approach of criticality from the low-temperature phase where another infinite family of universal PDF exists. We find that the LPA describes very well the functional form of the family of PDFs, once we correct for a global amplitude of the (logarithm of the) PDF and of $ζ$.

description: We present three Suzaku observations of the black hole candidate 4U 1957+11 (V1408 Aql) --- a source that exhibits some of the simplest and cleanest examples of soft, disk-dominated spectra. 4U 1957+11 also presents among the highest peak temperatures found from disk-dominated spectra. Such temperatures may be associated with rapid black hole spin. The 4U 1957+11 spectra also require a very low normalization, which can be explained by a combination of small inner disk radius and a large distance (>10 kpc) which places 4U 1957+11 well into the Galactic halo. We perform joint fits to the Suzaku spectra with both relativistic and Comptonized disk models. Assuming a low mass black hole and the nearest distance (3 M_sun, 10 kpc), the dimensionless spin parameter a* = Jc/GM^2 >~ 0.9. Higher masses and farther distances yield a*~1. Similar conclusions are reached with Comptonization models; they imply a combination of small inner disk radii (or, equivalently, rapid spin) and large distance. Low spin cannot be recovered unless 4U 1957+11 is a low mass black hole that is at the unusually large distance of >~ 40 kpc. We speculate whether the suggested maximal spin is related to how the system came to reside in the halo.

description: Given a surface of infinite topological type, there are several Teichmüller spaces associated with it, depending on the basepoint and on the point of view that one uses to compare different complex structures. This paper is about the comparison between the quasiconformal Teichmüller space and the length-spectrum Teichmüller space. We work under this hypothesis that the basepoint is upper-bounded and admits short interior curves. There is a natural inclusion of the quasiconformal space in the length-spectrum space. We prove that, under the above hypothesis, the image of this inclusion is nowhere dense in the length-spectrum space. As a corollary we find an explicit description of the length-spectrum Teichmüller space in terms of Fenchel-Nielsen coordinates and we prove that the length-spectrum Teichmüller space is path-connected.
Science Caching: Applying Geocaching to Mobile Citizen Science

description: Citizen science occurs in part when scientists work with volunteers to collect science data in particular field locations. The benefit is that citizen science eases and lessens the cost of collecting such information. Yet it has a variety of known problems. This document focuses on four specific citizen science problems concerning difficulties in data collection, data validation, volunteer training and volunteer coordination. The thesis is that these problems can be mitigated by applying aspects from another thriving location-based activity: the geocaching treasure hunt as enabled by mobile devices. Citizen science can exploit geocaching’s location-based design, its use of physical objects, and its user maintained content. To explore and critique this thesis, a prototype mobile system called Science Caching was developed, along with various scenarios that describe how it addresses issues in collection, validation, training and coordination. The system and scenarios – which serve as a working sketch – were shown to citizen science experts via an interview-based design critique. In particular, they provided feedback on the choice of the problems addressed by the system, the approach to the problems as realized by Science Caching, how those approaches could be extended, and what other areas in citizen science they could be applied to. The results were analyzed via affinity diagramming, which uncovered various overarching themes. Generally, the combination of geocaching and mobility was received quite positively, where participants indicated various areas where it would be applicable. Problems and improvements were also suggested, giving insight into future iterations of the method and the system.
Graphene p-n junctions with nonuniform Rashba spin-orbit coupling

description: Linear conductance of graphene-based p-n junctions with Rashba spin-orbit coupling is considered theoretically. A square potential step is used to model the junctions, while the coupling is introduced in terms of the Kane-Mele model (C.L. Kane and E.J. Mele, Phys.Rev.Lett. 95, 226801(2005)). The main objective is a description of electronic transport in junctions where Rashba parameter is nonuniform. Such a nonuniformity can appear when graphene is asymmetrically covered with atomic layers, or when Rashba coupling is strongly dependent on electric field. It is shown that conductance is significantly modified by the considered nonuniformity, which is most clearly manifested by an anomalous minimum at a certain potential step height.

description: Il Toolkit AGORAge è il risultato del percorso di un anno condotto nell’ambito del progetto di citizen science AGORAge: Ageing in a Caring Community e si rivolge a tutti coloro che sono interessati ad avviare progettualità mirate a porre le basi per la creazione di una “comunità che si prende cura”, nella quale l’inclusione sociale delle persone anziane assume centrale rilievo. Questo Toolkit può dunque fare da supporto a ricercatori e professionisti che si occupano e agiscono in campo sociale, nonché a rappresentanti istituzionali, amministrazioni locali e fornitori di servizi. Il suo obiettivo è duplice: da un lato, presentare alcune tecniche di valutazione e di intervento attraverso l’esperienza diretta del progetto AGORAge; dall’altro, fornire ulteriori risorse, quali buone pratiche, strumenti e raccomandazioni, utili a sostenere la creazione di una comunità che si prende cura. L’utilità e la pertinenza di questi strumenti dipenderanno dal progetto specifico e dal contesto nel quale si intende adoperali, nonché dalla realtà che intende utilizzarlo. Tuttavia, indipendentemente da tali variabili, a risultare sempre fondamentale è la conoscenza della situazione di partenza, ossia comprendere i bisogni, le aspettative e i desideri delle persone coinvolte. A tale scopo è importante entrare in contatto fin dall’inizio con il gruppo a cui ci si rivolge e renderlo il più possibile partecipe durante le diverse fasi della ricerca. Vi invitiamo quindi a sfogliare il toolkit ed esaminare i concetti, metodi, tecniche, esempi e risorse proposti per familiarizzare con ciascuno di essi e valutarne l’applicabilità al vostro progetto e contesto.

description: The decay of the Z' boson into supersymmetric particles is studied. We investigate how these supersymmetric modes affect the current limits from the Tevatron and project the expected sensitivities at the LHC. Employing three representative supersymmetric Z' models, namely, E_6, U(1)_{B-L}, and the sequential model, we show that the current limits of the Z' mass from the Tevatron could be reduced substantially due to the weakening of the branching ratio into leptonic pairs. The mass reach for the E_6 Z' bosons is about 1.3-1.5 TeV at the LHC-7 (1 fb^{-1}), about 2.5 - 2.6 TeV at the LHC-10 (10 fb^{-1}), and about 4.2 - 4.3 TeV at the LHC-14 (100 fb^{-1}). A similar mass reach for the U(1)_{B-L} Z' is also obtained. We also examine the potential of identifying various supersymmetric decay modes of the Z' boson because it may play a crucial role in the detailed dynamics of supersymmetry breaking.

Joint spectral-timing modelling of the hard lags in GX 339-4: constraints on reflection models

description: The X-ray variations of hard state black hole X-ray binaries above 2 keV show 'hard lags', in that the variations at harder energies follow variations at softer energies, with a time-lag τdepending on frequency νapproximately as τ\propto ν^{-0.7}. Several models have so far been proposed to explain this time delay, including fluctuations propagating through an accretion flow, spectral variations during coronal flares, Comptonisation in the extended hot corona or a jet, or time-delays due to large-scale reflection from the accretion disc. In principle these models can be used to predict the shape of the energy spectrum as well as the frequency-dependence of the time-lags, through the construction of energy-dependent response functions which map the emission as a function of time-delay in the system. Here we use this approach to test a simple reflection model for the frequency-dependent lags seen in the hard state of GX 339-4, by simultaneously fitting the model to the frequency-dependent lags and energy spectrum measured by XMM-Newton in 2004 and 2009. Our model cannot simultaneously fit both the lag and spectral data, since the relatively large lags require an extremely flared disc which subtends a large solid angle to the continuum at large radii, in disagreement with the observed Fe Kαemission. Therefore, we consider it more likely that the lags > 2 keV are caused by propagation effects in the accretion flow, possibly related to the accretion disc fluctuations which have been observed previously.

Detecting and Fixing Emergent Behaviors in Distributed Software Systems Using a Message Content Independent Method

description: Distributed software Systems (DSS) and Multiagent Systems (MAS) as a sub-class of DSS can provide efficient and cost effective solutions for a wide range of applications. The distributed functionality and/or control in these systems and the local view of the scenarios of the systems can lead to unexpected behavior during execution time, known as Emergent Behaviors (EB) and Implied Scenarios (IS), which was not evident in the requirements and design phase. The new scenarios that are implied to the system can degrade the quality of service and/or cause irreparable damage. Detecting and fixing EB/IS in the early phases, may save costs of software projects by a factor of 20 to 100. In this thesis, we are investigating a new methodology for modeling and analyzing the behavior of software components/agents in order to certify their behavior in advance. Our research questions are: Q1: Is there any methodology that can detect common EB/IS in DSS/MAS without modeling the internal information/knowledge used in software components/agents? Q2: Is there a general approach that can detect EB/IS without human interference and is fully automated? First, we devised a catalogue of the common EB/IS that can arise in DSS/MAS. One of the main advantages of this catalogue is categorizing the EB/IS based on the reasons of occurrence, which helps in devising specific algorithms to detect each type of EB/IS, and can lead to devising solution repositories. The other contribution of our work is devising new modeling based on state machines and social network analysis. This modeling is a general method and can be implemented fully automated. Also, we devised algorithms for detecting the agents that will not show EB/IS in the system as a pre-processing phase. For classes of EB/IS in the catalogue, the detection methodology is devised and recommendations on how to fix the problem are provided. The results of our work shows that all of the EB/IS in various case studies specified in the literature can be detected with our method. Moreover, a new EB/IS is introduced which only can be detected with our modeling.

description: The Ebbinghaus Illusion, the creative work of this dissertation, is a collection of linked prose poems that make use of a variety of narrative strategies, both traditional and unusual. The linked prose poems present creative reactions (and rejections of) notions of typical trauma narratives as articulated by scholars such as Anne Whitehead, Cathy Caruth, Michelle Balev, and Laurie Vickroy. In addition, the work is also inspired by the work of space and place theorists, including the ideas of Edward Soja and Michael Foucault, who put forward pluralistic models of time and space, applicable to how a trauma narrative is read and processed by a reading audience. Thematically, the prose poems examine both the trauma and disorientation of Alzheimer’s disease, and the trauma of suicide. The prose poems are a collection of isolated memories that form a disjointed story about death and the processing of traumatic experience. Although these prose poems are presented in order, they can also be read arbitrarily, in order to produce an entirely different narrative experience. The text blurs notions of time and space to disorient the reader, and emphasizes the disorienting nature of traumatic experience. The critical afterword, “Monstrous Space: Trauma Narratives and Hybrid Poetics,” presents a discussion of trauma theory and space and place theory as it relates to the writing and reading of The Ebbinghaus Illusion. The afterword summarizes the major tenets of trauma theory, and relates the theory to a discussion of hybrid poetic formats, concentrating on the prose poem as a vehicle for traumatic narratives. The afterword also introduces the pluralistic models of time-space suggested by Foucault and Soja, and argues that the pluralistic models of “Thirdspace” and “Heterotopia” are integral to how a reader participates in the mental and physical clash of time and space found in trauma narratives. Unnatural narratology, focusing on the “test” format of the memoir, and the use of second person narration are addressed. Discussion of unnatural narrative strategies suggests the importance of non-mimetic narration in producing the disorientation of time and space that results from reading a trauma narrative.

description: Recent experiments showed that non-uniform strain can be produced by depositing graphene over pillars. We employed atomistic calculations to study the non-uniform strain and the induced pseudo-magnetic field up to 5000 Tesla in graphene on top of nano-pillars. By decreasing the distance between the nano-pillars a complex distribution for the pseudo-magnetic field can be generated. Furthermore, we performed tight-binding calculations of the local density of states (LDOS) by using the relaxed graphene configuration obtained from the atomistic calculations. We find that the quasiparticle LDOS are strongly modified near the pillars, both at low energies showing sub-lattice polarization, and at high energies showing shifts of the van Hove singularity. Our study shows that changing the specific pattern of the nano-pillars allows us to create a desired shape of the pseudo-magnetic field profile while the LDOS maps provide an input for experimental verifications by scanning tunneling microscopy.

description: Following clinical delineation of a rare disease, identification of the causative gene(s) is a crucial first step towards providing enhanced patient care and understanding disease aetiology. Disease gene discovery, especially when considered in the context of related disorders, can also provide new insight regarding normal development and physiology. Herein, I present two novel disease-causing genes: the ribosomal gene RPLP2 in Nager syndrome (NS) and the spliceosomal gene SNRPB in cerebro-costo-mandibular syndrome (CCMS). The mutations identified in SNRPB are the first example of de-regulated alternative splicing-coupled nonsense-mediated decay as a mechanism for human disease. NS and CCMS are both disorders of first and second pharyngeal arch development, with the jaw and ears being affected. Over the past five years, the association between disorders of craniofacial development and mutations in spliceosomal genes has become apparent with the discovery of SF3B4 in NS, EFTUD2 in mandibulofacial dysostosis type Guion-Almeida, and TXNL4A in Burn McKeown syndrome. The specificity of the phenotypes resulting from mutations in such ubiquitous genes has perplexed the scientific community, but it is at least clear that spliceosomal genes play a more prominent yet subtle role in development than previously thought. The association between Treacher Collins syndrome, which overlaps phenotypically with CCMS and NS, and the ribosomal genes TCOF1, POLR1C, and POLR1D has been known for longer. This work establishes NS as having both spliceosomal and ribosomal defects as a cause. In this thesis I discuss potential links between the mechanisms underlying ribosomal and spliceosomal defects in disorders of craniofacial development, particularly increased sensitivity to reactive oxygen species (ROS).

New Local Duals in Eternal Inflation

description: Global-local duality is the equivalence of seemingly different regulators in eternal inflation. For example, the light-cone time cutoff (a global measure, which regulates time) makes the same predictions as the causal patch (a local measure that cuts off space). We show that global-local duality is far more general. It rests on a redundancy inherent in any global cutoff: at late times, an attractor regime is reached, characterized by the unlimited exponential self-reproduction of a certain fundamental region of spacetime. An equivalent local cutoff can be obtained by restricting to this fundamental region. We derive local duals to several global cutoffs of interest. The New Scale Factor Cutoff is dual to the Short Fat Geodesic, a geodesic of fixed infinitesimal proper width. Vilenkin's CAH Cutoff is equivalent to the Hubbletube, whose width is proportional to the local Hubble volume. The famous youngness problem of the Proper Time Cutoff can be readily understood by considering its local dual, the Incredible Shrinking Geodesic.

Self-regulation and co-regulation : prospects and boundaries in an online environment

description: Industry self-regulation and governmental regulation compete for the best model of Internet regulation. This thesis challenges the argument that they have to be antagonistic schemes and evaluates the possibility of cooperation in the form of co-regulation or ‘regulated self-regulation’. It uses a comparative method to analyze the preference for the regulatory models in Europe, the United States and Canada, which draws upon the role of governments in a historical context and the impact of fundamental rights in the respective constitutional frameworks. Before considering the peculiarities of Internet regulation, the thesis identifies and analyzes the advantages and difficulties of both self-regulation and co-regulation. Whereas self-regulation lacks democratic legitimacy, has little incentive to detect violations and to maintain high standards, governments have the ability to compensate for some of these problems. In the Internet context, this analysis reveals the need to deal with regulatory effects of code, transborder conduct, and ways to sanction non-compliance. However, governments with traditional command-and-control legislature have not adapted to these specifics. A system that would suit the Internet environment is composed of certification and accreditation of codes of conduct, and support of self-regulatory institutions. The thesis proposes ten criteria for efficient co-regulation that attend to fundamental values and favor an open, transparent collaboration. It further evaluates the substitution of governmental influence by external self-regulatory bodies, and the integration of Internet users to create a democratic link between regulators and regulated. The ten criteria are applied to some exemplary regimes to demonstrate practical application and ways to improve existing regulation. This shows the potential of models in which the public sector defines the goals and the private sector offers the solutions.

description: Spontaneous natural biofilm concentrates microalgal biomass on solid supports. However, the biofilm is frequently susceptible to exfoliation upon nutrient deficiency, particularly found in aged biofilm. Therefore, this study highlights a novel biofilm cultivation technique by pre-depositing the algal organic matters from marine diatom, Navicula incerta onto microporous polyvinylidene fluoride membrane to further strengthen the biofilm developed. Due to the improvement in membrane surface roughness and hydrophobicity, cells adhered most abundantly to soluble extrapolymeric substances-coated (sEPS) (76×106±16×106 cells m−2), followed by bounded EPS-coated (57.67×106±0.33×106 cells m−2), internally organic matter (IOM)-coated (39.00×106±5.19×106 cells m−2), and pristine control the least (6.22×106±0.77×106 cells m−2) at 24th h. Surprisingly, only bEPS-coated membrane demonstrated an increase in cell adhesion toward the end of the experiment at 72 h. The application of the bio-coating has successfully increased the rate of cell attachment by at least 45.3% upon inoculation and achieved as high as 89.9% faster attachment at 72 hours compared to the pristine control group. Soluble polysaccharides and proteins might be carried along by the cells adhering onto membranes hence resulting in a built up of EPS hydrophobicity (>70% in average on bio-coated membranes) over time as compared with pristine (control) that only recorded an average of approximately 50% hydrophobicity. Interestingly, cells grown on bio-coated membranes accumulated more internally bounded polysaccharides, though bio-coating had no discernible impact on the production of both externally and internally bounded protein. The collective findings of this study reveal the physiological alterations of microalgal biofilms cultured on bio-coated membranes.
