description: We study the circular motion of massive and massless particles in a recently proposed quantum-corrected Schwarzschild black hole in loop quantum gravity. This solution is supposed to introduce small but non-zero quantum corrections in the low curvature limit. In this paper, we confine our attention to the shadow of the black hole and the geodetic precession of a freely falling gyroscope in a circular orbit. Despite the mathematical complexity of the metric, our results are exact and show that the black hole shadow decreases slightly in this solution while the quantum corrections introduce a non-trivial term in the geodetic precession frequency of the gyroscope.

description: We achieved three-dimensional (3D) computational ghost imaging with multiple photoresistors serving as single-pixel detectors using semi-calibrated lighting approach. We performed imaging in the spatial frequency domain by having each photoresistor obtain the Fourier spectrum of the scene at a low spectral coverage ratio of 5%. To retrieve a depth map of a scene, we inverted, apodized, and applied semi-calibrated photometric stereo (SCPS) to the spectra. At least 93.5% accuracy was achieved for the 3D results of the apodized set of images applied with SCPS in comparison with the ground truth. Furthermore, intensity error map statistics obtained at least 97.0% accuracy for the estimated surface normals using our method. Our system does not need special calibration objects or any additional optical components to perform accurate 3D imaging, making it easily adaptable. Our method can be applied in current imaging systems where multiple detectors operating at any wavelength are used for two-dimensional (2D) imaging, such as imaging cosmological objects. Employing the idea of changing light patterns to illuminate a target scene and having stored information about these patterns, the data retrieved by one detector will give the 2D information while the multiple-detector system can be used to get a 3D profile.

description: Residual amounts of pharmaceutical compounds (PhCs) and by-products are continually released into surface water with effluents from conventional wastewater treatment plants (WWTPs). This study evaluated the ability of fungal isolate to remove selected PhCs [carbamazepine (CBZ), diclofenac (DCF) and ibuprofen (IBP)] from wastewater. The fungus used was Rhizopus sp. which was isolated from tuberous roots of cassava (Manihot esculenta). The isolate exhibited an important removal efficiency up to 100% and this was linked to ligninolytic enzymatic activity for lignin peroxidase (15.29 ± 2.69U/L) and manganese peroxidase (85.22 ± 4.26U/L), except laccase. This activity was optimum on day 9 of treatment. PhC metabolites were identified during the experiment revealing the existence of a biotransformation process catalysed by the isolated fungus. The disappearance of PhCs was attributed to their biosorption and biotransformation. However, it was not possible to establish a relationship between the ligninolytic enzymatic activity and the removal efficiency, which leads to the conclusion that there are other fungal metabolites which also play an important role in the biotransformation and biodegradation of the selected PhCs.

Study of the opportunities and costs of preserving recreation sites along the lower Fraser River
Creators: name: Friesen, Brock Frederick James
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study is to examine the social opportunity cost of preserving specified recreation sites along the lower Fraser River. In achieving this purpose it does the following: 1. it examines the institutional arrangements whereby land is allocated to specific uses, 2. it identifies the potential recreation sites for possible preservation, 3. it assesses the nature and extent of the conflict between recreation sites and existing and potential industrial shoreland use, 4. it develops an analytic framework for examining the social opportunity cost of preserving recreation sites, 5. it applies the framework to determine the benefits which the region might forgo if it were to preserve the recreation sites identified. An examination of the institutional setting found that private markets alone may not provide recreation facilities in the lower Fraser in accordance with society's willingness to pay for them. Public institutions have evolved to regulate the market, however, and an analysis of the social opportunity cost of preserving recreation sites is made in order to assist decision makers in future shoreland allocations. For this analysis to be meaningful it was necessary to identify specific recreation sites, and to determine the nature and extent of the conflict between these and industrial use. Thirty-two major recreation sites were identified. About two-thirds of these were found to conflict with potential industrial needs for shoreland designated industrial by the Regional Plan, and with log storage activities of the forest industry. Ideally a technique for allocating shoreland to recreational or industrial uses should be based on an assessment of the benefits and costs of alternative land uses. However, an opportunity cost approach is all that is practicable at this time because of the difficulties associated with evaluating present and future recreation demands. A qualitative approach to the evaluation was devised because past attempts to measure social opportunity cost were not appropriate in this situation where concern was primarily with demand far into the future. The analysis focussed on the rental value differences between industrial use of shoreland and upland, the supply and demand for industrial shoreland, and the cost of log storage alternatives. The analysis produced four main findings. First, most firms do not attach a significantly higher rental value to shoreland than to upland sites. Second, the supply of waterway access is much greater than anticipated industrial demand, and the opportunity cost of preserving land with recreation potential is zero in the short run. Third, the study area has sufficient land designated industrial that a small reduction for the preservation of recreation sites will net affect the land market. Four, seasonal storage leases and bundle booming can be implemented to free recreation sites of stored logs without incurring a net opportunity cost.
Analytical challenges in the fields of Nanobioscience and Nanobiotecnology: integrated methods for separation and characterization

description: Nano(bio)science and nano(bio)technology play a growing and tremendous interest both on academic and industrial aspects. They are undergoing rapid developments on many fronts such as genomics, proteomics, system biology, and medical applications. However, the lack of characterization tools for nano(bio)systems is currently considered as a major limiting factor to the final establishment of nano(bio)technologies. 
Flow Field-Flow Fractionation (FlFFF) is a separation technique that is definitely emerging in the bioanalytical field, and the number of applications on nano(bio)analytes such as high molar-mass proteins and protein complexes, sub-cellular units, viruses, and functionalized nanoparticles is constantly increasing. This can be ascribed to the intrinsic advantages of FlFFF for the separation of nano(bio)analytes. FlFFF is ideally suited to separate particles over a broad size range (1 nm-1 μm) according to their hydrodynamic radius (rh). The fractionation is carried out in an empty channel by a flow stream of a mobile phase of any composition. For these reasons, fractionation is developed without surface interaction of the analyte with packing or gel media, and there is no stationary phase able to induce mechanical or shear stress on nanosized analytes, which are for these reasons kept in their native state. Characterization of nano(bio)analytes is made possible after fractionation by interfacing the FlFFF system with detection techniques for morphological, optical or mass characterization. For instance, FlFFF coupling with multi-angle light scattering (MALS) detection allows for absolute molecular weight and size determination, and mass spectrometry has made FlFFF enter the field of proteomics. 
Potentialities of FlFFF couplings with multi-detection systems are discussed in the first section of this dissertation. The second and the third sections are dedicated to new methods that have been developed for the analysis and characterization of different samples of interest in the fields of diagnostics, pharmaceutics, and nanomedicine. The second section focuses on biological samples such as protein complexes and protein aggregates. In particular it focuses on FlFFF methods developed to give new insights into: a) chemical composition and morphological features of blood serum lipoprotein classes, b) time-dependent aggregation pattern of the amyloid protein Aβ1-42, and c) aggregation state of antibody therapeutics in their formulation buffers. The third section is dedicated to the analysis and characterization of structured nanoparticles designed for nanomedicine applications. The discussed results indicate that FlFFF with on-line MALS and fluorescence detection (FD) may become the unparallel methodology for the analysis and characterization of new, structured, fluorescent nanomaterials.

description: Spatial phase inhomogeneity at the nano- to microscale is widely observed in strongly-correlated electron materials. The underlying mechanism and possibility of artificially controlling the phase inhomogeneity are still open questions of critical importance for both the phase transition physics and device applications. Lattice strain has been shown to cause the coexistence of metallic and insulating phases in the Mott insulator VO2. By continuously tuning strain over a wide range in single-crystal VO2 micro- and nanobeams, here we demonstrate the nucleation and manipulation of one-dimensionally ordered metal-insulator domain arrays along the beams. Mott transition is achieved in these beams at room temperature by active control of strain. The ability to engineer phase inhomogeneity with strain lends insight into correlated electron materials in general, and opens opportunities for designing and controlling the phase inhomogeneity of correlated electron materials for micro- and nanoscale device applications.

description: Dairy cattle manure with bedding (CB), including manure, urine, water, and shavings, is lignocellulosic biomass and needs to be pre-treated in anaerobic reactors to enhance biomass digestibility. This study analyzed the technical and economic feasibility of physical treatment (milling) and alkaline treatment of CB for biogas production. Pre-treatment included drying, milling, and alkaline hydrolysis at room temperature for 24 h. Maximum biogas production was determined using the biochemical methane potential (BMP) test. Physicochemical analyses were performed to characterise CB before and after pre-treatment and the BMP test. The characteristics of the lignocellulosic material were examined by scanning electron microscopy. The economic feasibility (return on investment) of each treatment (USD per ton of CB) was determined. Treatment with 3% NaOH achieved the highest biogas production (771 mL per kg of volatile solids) and was 104.5% higher than that of milling and 124.7% higher than that of chemical pre-treatment with 4% NaOH. The analysis of economic feasibility showed that the payback period of treatment with 3% NaOH was 1.4 years for scenario 1 (continuous stirred tank reactor - CSTR) and 3 years for scenario 2 (covered lagoon digester). These results demonstrate the feasibility of producing biogas as a renewable energy source via the anaerobic digestion of CB.

description: Recent observations have found that the age distribution of star clusters (SCs) in the Small Magellanic Cloud (SMC) shows a sharp peak around 2 Gyr ago. However, it is theoretically unclear what physical processes are responsible for such sudden formation of SCs in the SMC. Here we investigate whether massive SCs with initial masses more than $10^5$ $\text{M}_\odot$ can be formed during tidal interaction of the SMC with the Large Magellanic Cloud (LMC) about 2 Gyr ago, based on our new simulations, which include molecular hydrogen formation on dust grains and SC formation within giant molecular clouds (GMCs). We find that the formation of GMCs with masses more than $10^5$ $\text{M}_\odot$ can be dramatically enhanced due to the tidal force of the LMC-SMC interaction. We also find that gravitationally bound massive SCs can be formed within these GMCs, though their mean stellar densities ($10^4$ $\text{M}_\odot \text{pc}^{-3}$) are systematically lower than those of the genuine globular clusters (GCs). All simulated SCs have diffuse extended stellar envelopes that were formed from multiple merging of sub clusters within their natal GMCs. Furthermore, we find that some of the simulated SCs can have considerable global internal rotation and substructures surrounding them. Based on these simulation results, we discuss the origin of the observed diverse properties of SCs in the SMC and the physical roles of galaxy interaction in the formation of massive SCs from GMCs.

description: Symmetry-induced vortex-antivortex configurations in superconducting squares and triangles were predicted earlier; yet, they have not been resolved in experiment up to date. Namely, with vortex-antivortex states being highly unstable with respect to defects and temperature fluctuations, it is very unlikely that samples can be fabricated with the needed quality. Here we show how these drawbacks can be overcome by strategically placed nanoholes in the sample. As a result, (i) the actual shape of the sample becomes far less important, (ii) the stability of the vortex-antivortex configurations in general is substantially enhanced, and (iii) states comprising novel giant-antivortices (with higher winding numbers) become energetically favorable in perforated disks. In the analysis, we stress the potent of strong screening to destabilize the vortex-antivortex states. In turn, the screening-symmetry competition favors stabilization of new asymmetric ground states, which arise for small values of the effective Ginzburg-Landau parameter kappa.

description: Conventional growth literature fails to incorporate technical change and investment as endogenous variables; Marxian growth literature is bedeviled indeterminacies surrounding technical change and rate of profit. Both sets of problems are addressed using a two-sector (capital good, consumer good) model, in which capitalists accumulate coexisting vintages of techniques. The parameters of the latest technique are determined by maximizing the innovator's profit, constrained by diminishing returns to mechanization. The model describes the differential impact of goods-, capital-, and labor-market equilibrium on the sectors, as the economy converges to a proportional growth path. Conditions are identified under which prices approach labor values over time; and under which Marx's "rising composition" and "falling profit rate" tendencies are realized. (Auszug Titelseite)

Simulations of globular clusters within their parent galaxies: Metallicity spreads and anomalous precursor populations

description: Recent observations of globular clusters (GCs) suggest that elemental abundance variations may exist between first-generation (1G) stars. We propose that metal abundance ('metallicity') spreads within GC forming giant molecular clouds (GMCs) can influence the iron abundances of future cluster members. To investigate this, we use original hydrodynamical simulations to model GMC formation in a high redshift dwarf galaxy. Our simulations self-consistently model physical processes such as stellar feedback, dust formation and destruction, and molecular gas formation on dust grains, making them well suited to the study of GMC formation. We conclude that iron abundance variations in GMCs are due to the merging of gas clumps and self-enrichment processes. The metallicity dispersions of GC forming clumps is ~0.1 dex, reflecting a growing number of studies that claim a non-zero dispersion within GCs. The galactic gas fraction is a key parameter for the formation of clumps and the metallicity 'floor' observed for both Galactic and extragalactic GCs are associated with the parent galaxy's capacity to form massive GMCs. Finally, we argue that GMCs have the potential to trap surrounding metal-poor galactic disc stars, which we interpret as a precursor population (0G). These low metallicity stars are representative of the [Fe/H] value of the host dwarf and thus the chemistry of this 0G may be a fossilized record of the parent galaxy. These results depend on the initial metallicity and radial gradient of the galaxy, the threshold gas density for star formation, and the star formation prescription.

description: Automatic font generation is an imitation task, which aims to create a font library that mimics the style of reference images while preserving the content from source images. Although existing font generation methods have achieved satisfactory performance, they still struggle with complex characters and large style variations. To address these issues, we propose FontDiffuser, a diffusion-based image-to-image one-shot font generation method, which innovatively models the font imitation task as a noise-to-denoise paradigm. In our method, we introduce a Multi-scale Content Aggregation (MCA) block, which effectively combines global and local content cues across different scales, leading to enhanced preservation of intricate strokes of complex characters. Moreover, to better manage the large variations in style transfer, we propose a Style Contrastive Refinement (SCR) module, which is a novel structure for style representation learning. It utilizes a style extractor to disentangle styles from images, subsequently supervising the diffusion model via a meticulously designed style contrastive loss. Extensive experiments demonstrate FontDiffuser's state-of-the-art performance in generating diverse characters and styles. It consistently excels on complex characters and large style changes compared to previous methods. The code is available at https://github.com/yeungchenwa/FontDiffuser.

description: We analyze the behavior of the wave function $ψ(x,t)$ for one dimensional time-dependent Hamiltonian $H=-\partial_x^2\pm2δ(x)(1+2r\cosωt)$ where $ψ(x,0)$ is compactly supported. We show that $ψ(x,t)$ has a Borel summable expansion containing finitely many terms of the form $\sum_{n=-\infty}^{\infty} e^{i^{3/2}\sqrt{-λ_{k}+n\omegai}|x|} A_{k,n} e^{-λ_{k}t+nωit}$, where $λ_k$ represents the associated resonance. This expression defines Gamow vectors and resonances in a rigorous and physically relevant way for all frequencies and amplitudes in a time-dependent model. For small amplitude ($|r|\ll 1$) there is one resonance for generic initial conditions. We calculate the position of the resonance and discuss its physical meaning as related to multiphoton ionization. We give qualitative theoretical results as well as numerical calculations in the general case.

Metaphysical hunger and distaste in the notebooks of Malte Laurids Brigge by Rainer Maria Rilke, Hunger by Knut Hamsun aand Nausea by Jean-Paul Sartre
Creators: name: Frimer, Victoria
Publisher: name: University of British Columbia
Year: 2010

description: In many works of modern fiction the theme of alienation is presented in terms of a spiritual hunger or starvation. Concurrently images and metaphors of distaste crop up as the inevitable adjuncts to feelings of spiritual deprivation or hunger. The metaphor of distaste is projected onto the image of modern urban society and is consciously or unconsciously blamed for the hero's sense of estrangement. Rilke's presentation of this problem in The Notebooks of Malte Laurids Brigge centres on a young man's self-observation during a period of spiritual as well as national exile. The Rilkean hero's emphasis on childhood memories contributes a great deal towards establishing the premise that the modern hero's feeling of anomie or spiritual hunger is the consequence of a character predisposition towards introversion, daydreaming, and creativity, in short the "Tonio Kroeger" portrait of a specific type of artistic temperament. In Hamsun's Hunger and Sartre's Nausea the two respective heroes are presented in terms of their current psychological reactions to a large, fundamentally anonymous city. In all three novels I have focussed on the themes of hunger and distaste and attempted to explain the mariner in which these psychologically motivated perceptions become confused with one another (in the mind of the protagonist) and in their confusion reflect the process of an estrangement which begins with an estrangement from society and ends with an estrangement from self. While little reference is made to psychological theory, the particular approach of this study reflects indirectly my reading of the psychoanalytical writing of Dr. Edmund Bergler.

This current originated in the work of Kalecki and Steindl in the 1940s and early 1950s, who attempted, on the one hand, to bring a fresh interpretation of Marx's main "laws of motion of capitalism", by using the then new Keynesian insights à l'époque, and on the other hand, sought to reformulate Keynesian theories of effective demand starting from Marx's schemes of reproduction and some well known underconsumptionist passages in Capital.

description: We present numerical evidence of a novel propagation mode for superfast impact ionization fronts in high-voltage Si $p^+$-$n$-$n^+$ structures. In nonlinear dynamics terms, this mode corresponds to a pulled front propagating into an unstable state in the regime of nonlocalized initial conditions. Before the front starts to travel, field-ehanced emission of electrons from deep-level impurities preionizes initially depleted $n$ base creating spatially nonuniform free carriers profile. Impact ionization takes place in the whole high-field region. We find two ionizing fronts that propagate in opposite directions with velocities up to 10 times higher than the saturated drift velocity.

description: To illuminate how electroweak symmetry breaking shapes the physical world, we investigate toy models in which no Higgs fields or other constructs are introduced to induce spontaneous symmetry breaking. Two models incorporate the standard SU(3)_c x SU(2)_L x U(1)_Y gauge symmetry and fermion content similar to that of the standard model. The first class--like the standard electroweak theory--contains no bare mass terms, so the spontaneous breaking of chiral symmetry within quantum chromodynamics is the only source of electroweak symmetry breaking. The second class adds bare fermion masses sufficiently small that QCD remains the dominant source of electroweak symmetry breaking and the model can serve as a well-behaved low-energy effective field theory to energies somewhat above the hadronic scale. A third class of models is based on the left-right--symmetric SU(3)_c x SU(2)_L x SU(2)_R x U(1)_{B-L} gauge group. In a fourth class of models, built on SU(4)_{PS} x SU(2)_L x SU(2)_R gauge symmetry, lepton number is treated as a fourth color. Many interesting characteristics of the models stem from the fact that the effective strength of the weak interactions is much closer to that of the residual strong interactions than in the real world. The Higgs-free models not only provide informative contrasts to the real world, but also lead us to consider intriguing issues in the application of field theory to the real world.

description: We present the analysis of three kinds of oscillating behavior using multi-wavelength observations of the 10 November 2013 (SOL2013-11-10T05:14) circular-ribbon flare. This event is a typical circular-ribbon flare with an outer spine structure and homologous jets. We found three kinds of oscillations (or perturbations): i) flux oscillation (or QPP) with a dominant period of about 20 seconds in X-ray, EUV, and microwave emissions, ii) periodic jets with an intermittent cadence of around 72 seconds, iii) an outer loop perturbing half a cycle with a duration of about 168 seconds. Similar to the periodic jets that could be produced by a nonthermal process, like repeated magnetic reconnection, the flare QPP detected in the thermal emissions could have the same origin as the oscillation seen in the nonthermal emissions. The outer-loop perturbation is possibly triggered by a blast wave driven by the circular-ribbon flare, or it might be modulated by the sausage wave or the slow magnetoacoustic wave. The results obtained provide data for further numerical studies on the physical origin of the flare oscillations.

description: Introduction. Cardiovascular disease (CVD) represents the main cause of morbidity and mortality in kidney recipients. This study was undertaken to assess the impact of functional polymorphisms located in cytokine and apoptosis genes on CVD after kidney transplantation. Cytokine polymorphisms, generally located in gene regulatory regions, are
associated with high and low cytokine production and are likely to modulate the magnitude of inflammatory responses following transplantation, depending on the balance between the levels of pro-inflammatory and antiinflammatory
cytokines. The role of apoptosis in atherosclerosis has not been completely elucidated, and here we explored the hypothesis that the heterogeneity in cardiovascular risk in kidney recipients may also be linked to functional polymorphisms involved in apoptosis induction. Purpose. In the search for relevant genetic markers of predisposition to
CVD after renal transplant, the present investigation was undertaken to identify the clinical impact of polymorphisms of cytokines TNF-α, TGF-β, IL-10, IL-6, IFN-γ and IL-8 and of apoptosis genes Fas and Caspase 9 in a population of kidney transplant recipients. Materials and methods. The study involved 167 patients who received cadaveric kidney transplantation at our centre between 1997 and 2005 (minimum follow-up of 12 months); 35 of them had experienced
cardiovascular events (CVD group) and 132 had no cardiovascular complications (non-CVD group). Genotyping was performed using RFLP (Restriction Fragment Length Polymorphism) for RFLP per IL-8/T-251A, Fas/G-670A e Casp9/R221Q polymorphism and SSP (Sequence Specific Primer) for TNF-α/G-308A, TGF-β/L10P, TGF-β/R25P, IL-10/G-1082A, IL-
10/C-819T, IL-10/C-592A, IL-6/G-174C, IFN-γ/T+874A polymorphisms.Results. We found a significant difference in TNF-α and IL-10 genotype frequencies between the patients who had suffered cardiovascular events and those with no CVD history. The high producer genotype for proflogistic cytokine TNF-α appeared to have a significantly superior
prevalence in the CVD group compared to the non-CVD group (40.0% vs 21.2%) and it resulted in a 2.4-fold increased cardiovascular risk (OR=2.361; p=0.0289). On the other hand, the high producer genotype for the antiinflammatory cytokine IL-10 was found in 2.8% of the CVD group and in 16.7% of non-CVD group; logistic regression showed a 0.3-fold reduced risk of CVD associated with genetically determined high IL-10 production (OR=0.278; p<0.0001). The other polymorphisms did not prove to have any impact on CVD.
Conclusions. TNF-α and IL-10 gene polymorphisms might represent cardiovascular risk markers in renal transplant recipients.

description: In the present study, we synthesized a cationic lignosulfonate hydrogel (LS-g-P (AM-co-DAC)) by grafting acrylamide (AM) and acryloxyethyl trimethyl ammonium chloride (DAC) onto sodium lignosulfonate (LS) via free radical copolymerization. The solution pH, contact time, initial concentration and temperature were comprehensively investigated through static adsorption method for the adsorption behaviors of CrⅥ by hydrogel. The experimental results show that the best conditions were temperature of 30°C, dosage of 0.1 g, pH = 3, concentration of 50 mg/L, and contact time = 2 h with removal efficiencies above 70%, and adsorption capacity of 18.14 mg·g-1. The adsorption process followed the Langmuir isothermal model, indicating monolayer adsorption, and the maximum adsorption capacity was 58.86 mg·g-1. Adsorption kinetics results show that the pseudo-second-order kinetic model dominated the adsorption process, and the adsorption activation energy was 5.489 kJ·mol-1. In addition, the adsorption involved spontaneous exothermic and entropy reduction. The combination of FT-IR, SEM and XRD were used to characterize the structure and properties of the prepared hydrogel, and the adsorption mechanism was the result of electrostatic attraction, physical and chemical adsorption, and hydrogen bond. The hydrogel has good regenerative properties after desorption. Overall, this work synthesized an environmentally friendly biomass lignin-based hydrogel, which can be used as an adsorbent for the treatment of anionic pollutants, and explored a new method for the high-value utilization of industrial lignin.

description: Denote by $H(t)=(H_1(t),...,H_N(t))$ a function in $t\in{\mathbb{R}}_+^N$ with values in $(0,1)^N$. Let $\{B^{H(t)}(t)\}=\{B^{H(t)}(t),t\in{\mathbb{R}}^N_+\}$ be an $(N,d)$-multifractional Brownian sheet (mfBs) with Hurst functional $H(t)$. Under some regularity conditions on the function $H(t)$, we prove the existence, joint continuity and the Hölder regularity of the local times of $\{B^{H(t)}(t)\}$. We also determine the Hausdorff dimensions of the level sets of $\{B^{H(t)}(t)\}$. Our results extend the corresponding results for fractional Brownian sheets and multifractional Brownian motion to multifractional Brownian sheets.

description: Phosphorus recovery from sewage sludge as secondary raw materials or as a direct P-rich fertilizer is one of the top frontrunner solutions to tackle Phosphorus (P) scarcity and depletion. However, the efficiency of this P recovery process greatly depends on its phosphorus dissolution potential, which in return relies on the phosphorus speciation in the sewage sludge. This article investigates the potential correlation between P speciation in sewage sludge and the iron-based P removal technologies used in sewage treatment plants (STP) through an innovative sequential extraction method based on the SEDEX method that distinguishes quantitatively between ferrous bound phosphate and ferric bound phosphate. XRD and SEM-EDX were also used to characterize P and Fe species in the studied sludge qualitatively. Principal component analysis showed that the sludge characterized by P bound to ferric iron (as the dominant P fraction) are mostly correlated with sludge produced from the CPR process (chemical phosphorus removal) and primary sludge. Moreover, sludge with a non-negligible amount of P bound to ferrous iron were correlated with sludge from the mixed EBPR-CPR process (Enhanced Biological P Removal assisted with CPR). However, Vivianite was only found in CPR sludge with Fe/P molar ratio higher than 0.6.
