description: Bell nonlocality -- the existence of quantum correlations that cannot be explained by classical means -- is certainly one of the most striking features of quantum mechanics. Its range of applications in device-independent protocols is constantly growing. Many relevant quantum features can be inferred from violations of Bell inequalities, including entanglement detection and quantification, and state certification applicable to systems of arbitrary number of particles. A complete characterisation of nonlocal correlations for many-body systems is, however, a computationally intractable problem. Even if one restricts the analysis to specific classes of states, no general method to tailor Bell inequalities to be violated by a given state is known. In this work we provide a general construction of Bell inequalities that are maximally violated by graph states of any prime local dimension. These form a broad class of multipartite quantum states that have many applications in quantum information, including quantum error correction. We analytically determine their maximal quantum violation, a number of high relevance for device-independent applications of Bell inequalities. Finally, we show that these inequalities can be used for self-testing of multi-qutrit graph states such as the well-known four-qutrit absolutely maximally entangled state AME(4,3).

description: Drawing on lessons from 10 Minnesota and Wisconsin colleges that piloted multiple measures systems for placing students into developmental and college-level courses, this guide from CCRC and MDRC provides recommendations for other colleges interested in implementing or testing their own multiple measures systems. Beginning with the rationale behind changing assessment practices, the guide outlines what a multiple measures assessment system is, what it takes to get started, the personnel involved, and the costs that may be incurred in the design and planning processes.

Recent evidence suggests that relying on traditional placement tests misplaces substantial numbers of students, with many going into developmental education who could have been successful in college-level courses. Multiple measures placement systems that use alternative measures alongside the traditional tests will potentially provide more accurate results and better student outcomes. Still, practitioners may be hesitant to change their current practices, skeptical about the measures used, or unsure where to start. The information in this guide addresses these concerns and provides recommendations for how to approach each step of the implementation process.

description: We study the connection between the quark orbital angular momentum and the pretzelosity transverse-momentum dependent parton distribution function. We discuss the origin of this relation in quark models, identifying as key ingredient for its validity the assumption of spherical symmetry for the nucleon in its rest frame. Finally we show that the individual quark contributions to the orbital angular momentum obtained from this relation can not be interpreted as the intrinsic contributions, but include the contribution from the transverse centre of momentum which cancels out only in the total orbital angular momentum.

title: Leadership in a First Nations Community: Learning from Leaders’ Stories and Building Capacity in Support of First Nations Children and Youth

description: The history of Canada, much like that of the United States, is mired in colonialism. One outcome of colonialism was the cultural genocide of the First Nations persons who lived on Turtle Island Millennia before the arrival of primarily European settlers (Battiste, 2010). Through policy decisions and actions, First Nations persons experienced—and continue to experience—discrimination, racism, harassment, violence, trauma, and death at the hands of white settlers (Duthie et al., 2019). The educational realm, including leadership, has been Eurocentric, centering European thinking, lifestyles, contributions, representation, and more (Khalifa et al., 2019). A scan of the literature in the area of community leadership is sparse in Indigenous representation. This paper endeavours to work with one indigenous community to explore and highlight First Nation leadership. Specifically, how educational and community leadership occurs among one First Nations community in Ontario, Canada. This single-case study comprising eleven qualitative interviews seeks to understand, through the eyes of First Nations leaders, how adult First Nations leaders engage in and foster leadership with children and youth in the Chippewas of the Thames First Nation community, and how the children and youth in turn provide shared leadership in their community. This study is of significance in that it aims to add to the discourse of decolonization (Diversi & Moreira, 2016), specifically the decolonization of First Nations leadership, which is not widely studied in the literature. The implications of this small case study are of particular significance in the Ontario educational realm, where the work continues to for First Nation leaders and could perhaps be expanded to include other First Nations communities with a view to informing policy that would decenter white worldviews and make space for centering and including conceptions of leadership from First Nations people.

Education, Higher--Evaluation
Developmental studies programs

description: CUNY Start, a pre-matriculation program developed by the City University of New York, seeks to help the lowest placed developmental education students become college ready in just one semester. The program targets incoming students who are assessed as needing remediation in math, reading, and writing by providing intensive instruction for one semester while students delay enrollment in college. It uses a conceptual student-centered curriculum and instructional delivery method and provides a robust approach to staffing and training that allows instructors to learn to implement these strategies while under the tutelage of experienced teachers. It also provides advising, tutoring, and a weekly seminar that teaches students skills they need to succeed in college. Students pay only $75 for the program and do not use financial aid.

This report describes the early findings of a random assignment evaluation and implementation study of CUNY Start by CCRC, MDRC, and CUNY. After following CUNY Start and control group students for three semesters, the researchers found: CUNY Start was implemented as it was designed, and the contrast between the program and the colleges’ standard developmental courses and services was substantial. During the first semester in the study, program group students made substantially more progress through developmental education than control group students. Control group students earned more college credits than program group students, as predicted by CUNY Start’s designers. During the second semester, program group students enrolled at CUNY colleges either in CUNY Start or in non-CUNY Start courses at a higher rate than control group students.

A final report will look at CUNY Start students’ persistence in college, college credit accumulation, and graduation rates. Another paper will detail CUNY Start’s math curriculum and pedagogy, and a brief will focus on CUNY Start’s staff recruitment, induction, and professional development. CUNY will also create a CUNY Start “Practice Guide.”

description: In the framework of Nambu Mechanics, we have recently argued that Non-Hamiltonian Chaotic Flows in $ R^{3} $, are dissipation induced deformations, of integrable volume preserving flows, specified by pairs of Intersecting Surfaces in $R^{3}$. In the present work we focus our attention to the Lorenz system with a linear dissipative sector in its phase space dynamics. In this case the Intersecting Surfaces are Quadratic. We parametrize its dissipation strength through a continuous control parameter $ε$, acting homogeneously over the whole 3-dim. phase space. In the extended $ε$-Lorenz system we find a scaling relation between the dissipation strength $ ε$ and Reynolds number parameter r . It results from the scale covariance, we impose on the Lorenz equations under arbitrary rescalings of all its dynamical coordinates. Its integrable limit, ($ ε= 0 $, \ fixed r), which is described in terms of intersecting Quadratic Nambu "Hamiltonians" Surfaces, gets mapped on the infinite value limit of the Reynolds number parameter (r $\rightarrow \infty,\ ε= 1$). In effect weak dissipation, through small $ε$ values, generates and controls the well explored Route to Chaos in the large r-value regime. The non-dissipative $ε=0 $ integrable limit is therefore the gateway to Chaos for the Lorenz system.

Personhood and responsibility
Creators: name: Topornycky, Joseph Stephen
Publisher: name: University of British Columbia
Year: 2012

description: Understanding human behavior as caused by some combination of genetics, environment, and upbringing is often taken to undermine the belief that human beings can be truly morally responsible. The root of this problem is in an apparent conﬂict between the casual thesis and the idea of human beings as persons that is premised in moral responsibility. I argue that this con- ﬂict is based on two related misunderstandings. Understood properly, moral responsibility is grounded in our aﬀective responses to others modiﬁed by a reﬂective understanding of those responses under the idea of self-government according to standards. It is through a commitment to those standards that we come to be persons, understood as a distinct moral category.

description: We work out the strongly interacting sector of a non-minimal Universal Extra Dimension (nmUED) scenario with one flat extra spatial dimension orbifolded on S^1/Z_2 in the presence of brane-localized kinetic and Yukawa terms. On compactification, these terms are known to have significant, nontrivial impact on the masses and the couplings of the Kaluza-Klein (KK) excitations. We study the masses of the level `1' KK gluon and the quarks and find the modified strong interaction vertices involving these particles. The scenario conserves KK parity. Possibility of significant level-mixing among the quarks from different KK-levels is pointed out with particular reference to the top quark sector. Cross sections for various generic final states involving level `1' KK-gluon and KK-quarks from first two generations are estimated at the Large Hadron Collider (LHC) via an implementation of the scenario in MadGraph-5 with the help of FeynRules. The decay branching fractions of both strong and weakly interacting KK excitations are studied to estimate yields in various different final states involving jets, leptons and missing energy. These are used to put some conservative constraints on the nmUED parameter space using the latest LHC data. Nuances of the scenario are elucidated with reference to the minimal Universal Extra Dimension (mUED) and Supersymmetry (SUSY) and their implications for the LHC are discussed.

description: We study the generation of two-qudit entangling quantum logic gates using two techniques in quantum optimal control. We take advantage of both continuous, Lie-algebraic control and digital, Lie-group control. In both cases, the key is access to a time-dependent Hamiltonian which can generate an arbitrary unitary matrix in the group SU($d^2$). We find efficient protocols for creating high-fidelity entangling gates. As a test of our theory, we study the case of qudits robustly encoded in nuclear spins of alkaline earth atoms and manipulated with magnetic and optical fields, with entangling interactions arising from the well-known Rydberg blockade. We applied this in a case study based on a $d=10$ dimensional qudit encoded in the $I=9/2$ nuclear spin in $^{87}$Sr, controlled through a combination of nuclear spin-resonance, a tensor AC-Stark shift, and Rydberg dressing, which allows us to generate an arbitrary symmetric entangling two-qudit gate such as CPhase. Our techniques can be used to implement qudit entangling gates for any $2\le d \le10$ encoded in the nuclear spin. We also studied how decoherence due to the finite lifetime of the Rydberg states affects the creation of the CPhase gate and found, through numerical optimization, a fidelity of $0.9985$, $0.9980$, $0.9942$, and $0.9800$ for $d=2$, $d=3$, $d=5$, and $d=7$ respectively. This provides a powerful platform to explore the various applications of quantum information processing of qudits including metrological enhancement with qudits, quantum simulation, universal quantum computation, and quantum error correction.

The adjacency matroid of a graph

Year: 2011

description: If $G$ is a looped graph, then its adjacency matrix represents a binary matroid $M_{A}(G)$ on $V(G)$. $M_{A}(G)$ may be obtained from the delta-matroid represented by the adjacency matrix of $G$, but $M_{A}(G)$ is less sensitive to the structure of $G$. Jaeger proved that every binary matroid is $M_{A}(G)$ for some $G$ [Ann. Discrete Math. 17 (1983), 371-376]. The relationship between the matroidal structure of $M_{A}(G)$ and the graphical structure of $G$ has many interesting features. For instance, the matroid minors $M_{A}(G)-v$ and $M_{A}(G)/v$ are both of the form $M_{A}(G^{\prime}-v)$ where $G^{\prime}$ may be obtained from $G$ using local complementation. In addition, matroidal considerations lead to a principal vertex tripartition, distinct from the principal edge tripartition of Rosenstiehl and Read [Ann. Discrete Math. 3 (1978), 195-226]. Several of these results are given two very different proofs, the first involving linear algebra and the second involving set systems or delta-matroids. Also, the Tutte polynomials of the adjacency matroids of $G$ and its full subgraphs are closely connected to the interlace polynomial of Arratia, Bollobás and Sorkin [Combinatorica 24 (2004), 567-584].

description: This thesis aims to address and understand the major themes of Reconciliation in Canada and Peru, focusing on their respective Truth and Reconciliation Commissions (TRCs). Transitional Justice is utilized as a framework to give understanding of what Reconciliation is and the tools typically used to achieve it and examines the unique historical, social, and political contexts of both countries. Ultimately this thesis identifies the political isolation and lack of Government support for Indigenous institutions as major challenges toward reconciliation in each case. In order to understand the groundwork leading to this political isolation the thesis delves into the historical legacies of colonialism and systemic violence, such as Canada's residential school system and Peru's internal conflict involving Sendero Luminoso (Shining Path), both of which specifically impacted Indigenous populations. The findings reveal that both nations face significant barriers to reconciliation, in regard to weak Government support for Indigenous institutions and shows evidence that the weak formal institutions in Peru has resulted in Indigenous institutions not being supported due to their substitutionary role. Whereas the strong formal institutions in Canada have resulted in Indigenous institutions not being supported due to their competitive role. The study creates a conversation surrounding institutional design and differing paths towards reconciliation providing evidence that the strong formal institutions of the Canadian state as resulted in a top-down pathway to Reconciliation. Whereas the weak formal institutions of Peru have resulted in a bottom-up pathway. Based on these findings the thesis concludes by advocating for a hybrid model that combines top-down and bottom-up reconciliation efforts to address these deep-rooted issues.

description: Materials have long served as a cornerstone of human creativity and the evolution of our built environment. However, the limited diversity of available materials and the increasing depletion of finite resources, exacerbated by fragmented modeling, analysis, and production processes, highlight the urgent need for integrated and selective methodologies. The emergence of computational media and advanced materials introduces new possibilities, enabling architects to interactively and efficiently conceive, evaluate, and produce well-performing products and processes. This thesis introduces PASSAGE, a comprehensive computational workflow designed to digitally configure, select, and produce material compositions for architectural applications based on customized performance criteria. At the center of PASSAGE lies an interactive workflow that automates the configuration and production of architectural objects through the strategic manipulation of material compositions. This workflow supports designers by an interactive interface, allowing for generation of performance datasets to meet specific user requirements in near-real time. The research presented in this thesis encompasses the design, development, and prototyping of the workflow using existing commercial software and fabrication technologies. The work includes the parametric and simulation modeling of geometry, material properties, and fabrication processes, all of which interact dynamically with a database, the designer, and fabrication machinery to ensure comprehensive control over the design, analysis, and production of architectural object models. The effectiveness of PASSAGE is demonstrated through the development of a visual programing code and a case study focused on the creation of a freeform-heterogeneous chair. This case study, realized through the workflow and a Grasshopper code, serves to evaluate and verify the integrated process from design to production using a 3D printer. The dual goals of this research are to empower architects with an interactive, efficient, and scalable computational workflow and to establish a holistic, integrated approach to material composition of architectural products.

description: Skew-monoidal categories arise when the associator and the left and right units of a monoidal category are, in a specific way, not invertible. We prove that the closed skew-monoidal structures on the category of right R-modules are precisely the right bialgebroids over the ring R. These skew-monoidal structures induce quotient skew-monoidal structures on the category of R-R-bimodules and this leads to the following generalization: Opmonoidal monads on a monoidal category correspond to skew-monoidal structures with the same unit object which are compatible with the ordinary monoidal structure by means of a natural distributive law. Pursuing a Theorem of Day and Street we also discuss monoidal lax comonads to describe the comodule categories of bialgebroids beyond the flat case.

description: We stabilize two-dimensional turbulent Kolmogorov flow by selectively altering the time rate of change of inviscid invariants (energy and enstrophy) of the flow. This method has earlier been demonstrated to modify the two-dimensional unforced decaying turbulent flow to reach steady states. However, Kolmogorov flow exhibits flow unsteadiness over a range of spatial and temporal scales which are driven by constant external forcing at wave number $k_f$. The energy injected at scale ($k \approx k_f$) is distributed to large ($k > k_f$) and small ($k < k_f$) wave numbers through interactions of different scales called direct and inverse energy cascading, respectively. The selective modification strategy autonomously identifies additional forcing inputs into the governing equations which results in the transformation of Kolmogorov flow into a non-trivial steady state. We demonstrate that this method is highly effective in altering the inverse energy cascading, a particularly intricate challenge in fluid dynamics. Intriguingly, we have also found that the steady states achieved through this approach resemble an invariant solution of the original Kolmogorov flow, highlighting the potential significance of our method.

description: A set $D \subseteq V(G)$ is a \emph{dominating set} of a graph $G$ if every vertex of $G$ not in $D$ is adjacent to at least one vertex in $D$. A \emph{minimum dominating set} of $G$, also called a $γ(G)$-set, is a dominating set of $G$ of minimum cardinality. For each vertex $v \in V(G)$, we define the \emph{domination value} of $v$ to be the number of $γ(G)$-sets to which $v$ belongs. In this paper, we find the total number of minimum dominating sets and characterize the domination values for $P_2 \square P_n$ and $P_2 \square C_n$.

Promoting change through collaboration : reshaping the professional boundaries of family physicians through the Division of Family Practice
Creators: name: Chan, Vivian Wing Yan
Publisher: name: University of British Columbia
Year: 2012

description: A collaborative framework is increasingly being used to promote change in the way health services are being provided. Collaborations have been studied mostly from a team perspective in health services research (HSR); system and institutional levels of analysis are underutilized. Applying an (neo) institutional perspective, this dissertation explored the role of interorganizational collaborative relationships in promoting practice change in family physicians. Specifically changes in the professional boundaries of family physicians were examined. The dissertation is comprised of two parts. The first study was a systematic qualitative examination of the HSR literature on the concept of professional boundary for family physicians. Fifty articles were reviewed. Conceptual distinctions used by family physicians to describe their role and their work were synthesized to form a multi-faceted notion of professional boundaries of family physicians (i.e., task-related, object-related, and relational). The second study was a case study of a new organizational form, the Division of Family Practice, in a suburban community in British Columbia. The new organizational form employed a collaborative framework to promote system and professional practice change in primary care. Findings were generated from interview texts, organizational documents, and participant observations. The study investigated how professional boundaries of family physicians are being reshaped through family physician’s involvement in collaborative relationships under the Division of Family Practice. Conclusion: collaborations provide a physical as well as a social space for partners (family physicians, the health authority, the government, and the medical association) to share, challenge, and shape each other’s perspectives, values, interests, and goals. The case study demonstrated the Division of Family Practice was successful at disrupting the physician institution and reshaping professional boundaries for family physicians as 1) the profession of family practice is undergoing a process of deinstitutionalization: the professional boundaries of family physicians are not as clear and distinct as they once were and have become a weakened institutional element; 2)the Division was able to disturb and reformulate the reward and sanction mechanisms for family physicians; and 3) the Division has enabled core assumptions and beliefs about family practice to be broken down and redefined.

description: In the pickling industry, corrosion can deteriorate the quality of equipment and supplies, causing financial losses and safety threats. Therefore, it has become crucial to develop novel corrosion inhibitors that are bioactive, efficient, affordable, medium-acid soluble, and ecologically safe to protect mild steel during industrial cleaning. In this work, three newly synthesized imidazo[1,2-a]pyridine derivatives were characterized by various spectroscopic techniques. The studied compounds were evaluated as corrosion inhibitors for mild steel in 1 M HCl medium using weight-loss, potentiodynamic polarization (PDP) and electrochemical impedance spectroscopy (EIS) techniques. The imidazopyridine derivatives showed excellent anticorrosion performance, their inhibitory efficiencies increased with the increase of inhibitors concentration and evolved in the following order: Imd2 (98.1%) >Imd1 (96.5%) >Imd3 (95.3%). This order was justified by the presence of two chlorine atoms in the ortho position of the Imd2 structure. The three Imd derivatives obeyed to the Langmuir isotherm, this explained the formation of an organic monolayer on the steel surface indicated by the scanning electron microscope (SEM) and the atomic force microscope (AFM). In addition, density functional theory (DFT) and molecular dynamics (MD) simulations were performed to reveal the anticorrosion mechanism. The present study illustrates at the microscopic level how mild steel resists corrosion and ensures the safety of pickling.

description: Objectives: Airports in the U.S. have gradually been transitioning to automated flight systems. These systems generate new flight paths over populated areas. While they can improve flight efficiency, the increased noise associated with these novel flight patterns potentially pose serious health threats to the overflown communities. In this case study, we estimated the monetary benefits relative to health losses associated with one significant change in flight patterns at LaGuardia Airport, year-round use of “TNNIS Climb”, which happened in 2012 as a result of flight automation in New York City. Prior to that, the use of the TNNIS Climb was limited to the U.S. Open tennis matches. Methods: We developed a decision-analytic model using Markov health states to compare the costs and quality-adjusted life years (QALYs) gained associated with the limited use of TNNIS (old status quo) and the year-round use of TNNIS (current status quo). The TNNIS Climb increases airplane noise to above 60 decibels (dB) over some of the most densely populated areas of the city. We used this increased exposure to noise as the basis for estimating ground-level health using data from sound monitors. The total costs (including both direct and indirect costs), QALYs, and the incremental cost-effectiveness ratio (ICER) were estimated for the limited versus the year-round use of the TNNIS Climb. Results: The incremental lifetime costs and QALYs per person exposed to noise associated with the limited versus the year-round use of TNNIS was $11,288, and 1.13, respectively. Therefore, the limited use of TNNIS had an ICER of $10,006/QALY gained relative to the year-round of TNNIS. Our analyses were robust to changes in assumptions and data inputs. Conclusions: Despite increases in efficiency, flight automation systems without a careful assessment of noise might generate flight paths over densely populated areas and cause serious health conditions for the overflown communities.
title: Unraveling the Regulation of Plant and Yeast Plastin Proteins: A Structural Determination Study

description: L-plastin is a 70 kDa protein normally found in white blood cells, where it plays a pivotal role in the formation of actin-rich protrusions required for cell motility. Interestingly, many cancers hijack the white blood cell’s ability to move around and transform into metastatic cancers by upregulating L-plastin. Despite the potential clinical implications of this protein, the function and regulation of L-plastin remain enigmatic, and its full-length structure has yet to be fully characterized. By elucidating the regulatory mechanism of this proposed cancer biomarker, we may find a new approach to manipulate it and thereby reduce the motility of metastatic cancers. Regulation of the actin-bundling activity of L-plastin has been presumed to involve a structural change brought about by the binding of calcium to the N-terminal calcium-binding region (EF-hands). Intriguingly, in plants and yeast this region seems to be conserved, and yet incapable of sensing calcium. This implies another calcium-sensing mechanism may be involved in its regulation. To gain deeper insights into the regulation of L-plastin, we investigated the EF-hands to identify potential proteins involved in modulating its activity and elucidated the structures of the EF-hands of plant and yeast plastins using X-ray crystallography. Using nuclear magnetic resonance (NMR), we uncovered a calcium-sensing protein, calmodulin (CaM), involved in binding and potentially regulating L-plastin. The high-resolution studies of the EF-hands in plants and yeast suggest unique regulatory mechanisms that could enable plant and yeast plastins to function autonomously, independent of calcium. Identifying new mechanisms for actin-bundling can have a significant impact on the advancement of drug-development for the treatment of metastatic cancers.

description: We introduce the notion of dissipative periodic lattice as an optical lattice with periodically distributed dissipative sites and argue that it allows to engineer unconventional Bose-Einstein superfluids with the complex-valued order parameter. We consider two examples, the one-dimensional dissipative optical lattice, where each third site is dissipative, and the dissipative honeycomb optical lattice, where each dissipative lattice site neighbors three non-dissipated sites. The tight-binding approximation is employed, which allows one to obtain analytical results. In the one-dimensional case the condensate is driven to a coherent Bloch-like state with non-zero quasimomentum, which breaks the translational periodicity of the dissipative lattice. In the two-dimensional case the condensate is driven to a zero quasimomentum Bloch-like state, which is a coherent superposition of four-site discrete vortices of alternating vorticity with the vortex centers located at the dissipative sites.

description: Harnessing quantum mechanics properties, quantum computers have the potential to outperform classical computers in many applications and are envisioned to affect various aspects of our society. Different approaches are being explored for building such computers. One of such potential approaches is Measurement based quantum computation (MBQC), introduced by Raussendorf and Briegel in 2001. In MBQC a large number of qubits are prepared in a highly entangled clusters, called cluster states. The required quantum computation is then performed by a sequence of measurements. Cluster states are being physically realized using continuous variables (CV) and discrete variables (DV) approaches. CV-based approaches can be further categorized as Frequency domain multiplexing (FDM), Time domain multiplexing (TDM), Spatial domain multiplexing (SDM) and hybrid. We discuss and compare these approaches in detail. We also discuss cluster states generation in DV and report some recent results where photons and superconducting qubits are used.

description: We explore the recent OPERA experiment of superluminal neutrinos in the framework of Special Relativity with de Sitter space-time symmetry (dS-SR). According to Einstein a photon is treated as a massless particle in the framework of Special Relativity. In Special Relativity (SR) we have the universal parameter $c$, the photon velocity $c_{photon}$ and the phase velocity of a light wave in vacuum $c_{wave}=λν$. Due to the null experiments of Michelson-Morley we have $c=c_{wave}$. The parameter $c_{photon}$ is determined by the Noether charges corresponding to the space-time symmetries of SR. In Einstein's Special Relativity (E-SR) we have $c=c_{photon}$. In dS-SR, i.e. the Special Relativity with SO(4,1) de Sitter space-time symmetry, we have $c_{photon}>c$. In this paper, the OPERA datum are examined in the framework of dS-SR. We show that OPREA anomaly is in agreement with the prediction of dS-SR with $R\simeq 1.95\times 10^{12}l.y.$ Based on the $p$-$E$ relation of dS-SR, we also prove that the Cohen and Glashow's argument of possible superluminal neutrino's Cherenkov-like radiation is forbidden. We conclude that OPERA and ICARUS results are consistent and they are explained in the dS-SR framework.

description: A hyperbranched polymer (PMEL) was prepared using melamine as central core by a modified “one pot” method. The polymer was characterized by nuclear magnetic resonance spectroscopy (1H NMR and 13C NMR), Fourier transform infrared microscopy (FTIR), Gel permeation chromatography (GPC) and thermogravimetric analysis (TGA). Effect of standing time, temperature and concentration of PMEL on the demulsification performance of a diesel-in-water emulsion was investigated in detail. The transmittance of aqueous phase reached 91.3% if 50 mg/L of PMEL was added into an O/W emulsion for 240 min at ambient temperature. The interfacial tensions (IFT), zeta potential and microscopic analysis were further measured to explore the possible demulsifying mechanism. The current work shows that PMEL has a great application prospect in the demulsification of oil-water emulsion.
