title: How does crowdfunding work? Understanding the process through its activity
Creators: name: Stiver, Alexandra
Publisher: name: The Open University
Year: 2016

description: Crowdfunding is a process featuring incremental financial donations from a ‘crowd’ of backers to help fund a project initiated by a creator. In recent years, crowdfunding has generated significant revenue as well as great interest from industry, government, and creative entrepreneurs. However, rate of successful funding for crowdfunding projects remains around 35% for global crowdfunding leader Kickstarter1, and lower yet for other platforms. The identified gap between crowdfunding growth and crowdfunding success rates prompts the overarching question driving this thesis: how does crowdfunding work? This question is explored and answered through the lens of activity, as activity is largely observable, is featured in every project, and has some degree of control for creators. Activity was uncovered using semi-structured interviews, online observation, and daily monitoring of four crowdfunding projects from pre- to post-funding. By cataloguing the specifics of crowdfunding activity, this thesis reveals the breadth of activity common to crowdfunding projects: financial, non-financial, online, and offline. Further, in mapping activity along a timeline, five distinct periods of crowdfunding activity are identified, each with specific aims. Additionally, the relationships guiding activity are assessed through discussion of community within crowdfunding, accentuating both emotional and behavioural investment in a project. The resulting insights are summarised into two categories of contributions. The first is the consolidation of elements of importance to crowdfunding. By making implicit features of crowdfunding explicit, this adds precision to an understanding of the crowdfunding process. The second is the identification of underlying principles and essential steps to crowdfunding, which can be used by project creators to maximise success. This thesis provides a broader understanding of crowdfunding, emphasising the extent to which successful projects engage stakeholder communities with financial and non-financial activity and outcomes over time, as well as across various sites.

description: Using a Kaluza-Klein reduction of the Dirac-Born-Infeld and Chern-Simons action we compute the four dimensional N=1 effective action for the massless modes of a D7-brane which is wrapped on a four-cycle of a compact Calabi-Yau orientifold. We do not consider a specific orientifold but instead determine the Kahler potential, the gauge kinetic functions and the scalar potential in terms of geometrical data of a generic orientifold and its wrapped four-cycle. In particular we derive the couplings of the D-brane excitations to the bulk moduli of the orientifold as they are important for the study of soft supersymmetry breaking terms. We relate the resulting Kahler geometry to the N=1 special geometry of Lerche, Mayr and Warner. Finally we comment on the structure of the D-term which is induced by a Green-Schwarz term in the Chern-Simons action.

description: The objective of the study was to analyse the use activities of selected elements of marketing mix by organic producers on farms in the Lubelskie Voivodeship. For that purpose, a survey was conducted on a group of 30 producers of organic food from the Lubelskie Voivodeship. Selection of the sample for testing was a deliberate choice. The respondents were among organic producers registered in the Lublin Agricultural Advisory Centre in Końskowola. This register is a list of certified producers from the area of Lublin who have demonstrated activity and sent their applications to the Centre. The conducted analysis and the obtained results indicate that respondent farmers expect aid for taking action in the field of promotion and distribution from organisations and institutions supporting development of organic production. They also expect help in reducing costs related to their organic production, as they are higher than in the case of traditional production.

description: High resolution (lambda / Delta-lambda = 50,000) K-band spectra of massive, embedded, young stellar objects are presented. The present sample consists of four massive young stars located in nascent clusters powering Galactic giant H II regions. Emission in the 2.3 micron 2--0 vibrational--rotational bandhead of CO is observed. A range of velocity broadened profiles seen in three of the objects is consistent with the emission arising from a circumstellar disk seen at various inclination angles. Br gamma spectra of the same spectral and spatial resolution are also presented which support an accretion disk or torus model for massive stars. In the fourth object, Br emission suggesting a rotating torus is observed, but the CO profile is narrow, indicating that there may be different CO emission mechanisms in massive stars and this is consistent with earlier observations of the BN object and MWC 349. To--date, only young massive stars of late O or early B types have been identified with clear accretion disk signatures in such embedded clusters. Often such stars are found in the presence of other more massive stars which are revealed by their photospheric spectra but which exhibit no disk signatures. This suggests the timescale for dissipating their disks is much faster than the less massive OB stars or that the most massive stars do not form with accretion disks.

description: The realization of a directed current for a quantum particle in a flashing asymmetric potential is studied. It is found that a positive current, i.e. in the direction expected for a conventional diffusive ratchet, can be attained at short times in the limit where the potential is weak and quantum diffusion dominates, while current reversal is obtained for stronger potentials. A single parameter, the ratio between the kicking frequency and the optical lattice potential strength, determines both the degree to which quantum effects dominate, and the possibility of obtaining a ratchet current. The effect should be readily observable in experiments.

title: The Development and Evaluation of Methods for the Screening of Steroids using Molecular Imprinted Polymers coupled with comprehensive Gas Chromatography/Mass Spectrometry and Aptamers coupled with Liquid Chromatography/Mass Spectrometry
Creators: name: Zulfiqar, Adnan
Publisher: name: The Open University
Year: 2016

description: The profiling of hormones is an important requirement in sports dope testing and it is increasingly being used for clinical applications. The screening of samples for the detection of steroids is usually undertaken in urine and these analyses present many challenges. Issues related to the complexity of the matrix, the separation of exogenous from endogenous species and the very low detection limits have placed increasing demands on clinical and International Olympic Commission accredited laboratories. Whilst liquid chromatography (LC) systems provide a highly sensitive detection method for targeted species, gas chromatography, especially when coupled to mass spectrometry, is considered preferable for the screening of a wider range of target and unknown species. Existing chromatography methods are not without their limitations, not least the difficulty in reproducibly derivatising the wide range of steroids that can be exogenously administered, in particular the so called ‘designer steroids’ which deliberately hinder this process. Initially, a pilot study was conducted to investigate whether aptamer-coated magnetic beads could provide a simple, low cost method for the extraction of estradiol from urine, prior to its detection and quantification with mass spectrometry. In reality, the process necessitated the use of additional solvent extraction steps to the standard method applied previously. These additional steps added complexity and were not without issue and the limit of detection was not found to be adequate for the proposed clinical purpose. The project explored the application of comprehensive gas chromatography/mass spectrometry (GC x GC/MS) coupled to bespoke molecular imprinted polymers (MIPS) as an alternative solution to the problem of the screening of multiple steroids in urine. Twelve structurally similar and commercially relevant steroids were used to develop the chromatographic method. Once optimised, these compounds were then extracted from synthetic urine using a MIP templated with testosterone and developed during the project. Significant improvements compared to commercially available C-18 materials were found. All the steroids were identified and detected when spiked at the 10 ng/ml level, as required by World Anti-Doping Agency (WADA) at the time. The method was further validated and then successfully applied to the extraction of designer steroids from synthetic urine, in the presence of the original steroids. Epistane, which has a different structure to testosterone, was not detected indicating the efficacy of the templating process.
Antimicrobial resistance in invasive pneumococcal disease
Creators: name: Winters, Meghan Lesley
Publisher: name: University of British Columbia
Year: 2010

description: Antimicrobial resistance in Streptococcus pneumoniae has increased in recent decades at a frightening pace. The infant conjugate vaccine program, introduced in BC in 2003, is a tool for the control of invasive pneumococcal disease (IPD) with substantial potential to combat antimicrobial resistance. The first phase of this thesis linked surveillance programs at the BC Centre for Disease Control and the National Centre for Streptococcus to evaluate recent trends in IPD incidence, serotype distribution, and antimicrobial resistance. Based on 1,288 reported cases of IPD over 2002-2005, there was a significant decrease in the incidence in children <5 years. Over half of reported cases (728/1,288) were referred for serotype and susceptibility testing. Of these, the proportion that were of vaccine-preventable serotypes declined from 68.9% to 43.8% between 2002 and 2005; in children <2 years, the decline was from 83.0% to 16.7%. The prevalence of isolates with reduced susceptibility was highest for trimethoprim-sulfamethazole (15.3% non-susceptible, 111/725 tested), penicillin (9.I%, 66/728), and erythromycin (9.l%, 661727), and to [greater than or equal to]2 classes of antimicrobials (10.3%, 75/728). Arguably, the most important driver of resistance is antimicrobial use. With access to BC’s rich province-wide prescription database, we were able to conduct a retrospective cohort study to investigate the risk posed by an individual’s prior antimicrobial consumption patterns. We obtained historical records from PharmaNet for all IPD cases reported from 2001 to February 2005 that had complete antimicrobial susceptibility testing (n=564). In multivariable modeling, use of trimethoprim-sulfamethoxazole was significantly associated with having a penicillin non-susceptible infection (OR=2.92, 95% CI:1.34-6.38). Penicillins (OR=2.12, 95% CI:1.13-3.98) or macrolides/lincosamides (OR=2.00,95% CI:1.09- 3.68) were independently associated with erythromycin non-susceptible infections, and trimethoprim-sulfamethoxazole with trimethoprimsulfamethoxazole non-susceptibility (OR=2.09, 95% CI:1.01-4.31). Of the macrolides, only azithromycin consumption posed a significant risk for erythromycin resistance, with an etiologic fraction of over two-thirds. The transfer of these findings into the policy realm provides timely evidence on epidemiological trends in IPD in the era of the conjugate vaccine, and informs on the risk posed by certain commonly prescribed antimicrobials. Class-specific risk measures can be used to direct targeted prescription policy action for the control of antimicrobial resistance.

description: While most shocks to the economy lead to disequilibria that can be anticipated and accommodated, some shocks lead to major disequilibria which are not easily recognized, at least initially, and can have wide-ranging consequences. For some groups in society, these consequences can be life altering in ways which reduce their wellbeing – they bear large costs of adjustment. Some previous shocks of this nature and their consequences are outlined in this article. One source of such shocks is changes in the arrangements under which international trade is conducted. One such event was accession of China to the WTO in 2001. The disequilibrium that followed China’s accession is discussed and tied to the political discontent being manifest in many developed countries in the middle of the second decade of the 21st century – fifteen years after accession.

The calculation is organized using the 1/N expansion of the 2PI effective action to next-to-leading order. For the gauge theory, we verify gauge fixing independence and consistency with the Ward identity. In the gauge theory, we find a nontrivial dependence on the fermion mass.

description: The myriad of litigation and class action suits surrounding Syngenta’s Viptera corn covers many issues that have been well addressed in previous litigation and literature. However, the case of Syngenta v Bunge raised the fascinating issue of ‘regulatory lag’, i.e., a situation where there are significant delays in approval of a GM product in an emerging export market, or differences in the regulatory approval timetable between significant export markets. In this case, Syngenta argued that Bunge’s blanket refusal to accept Viptera corn into its facilities because China had not yet approved the variety, even though the variety was approved in the United States and in many other larger export markets, amounted to illegal activity that would cause significant harm to Syngenta. Although the litigation was ultimately settled in December 2014 by a confidential agreement between the parties, the case raises significant issues for the technology developers, producers, handlers, processers and shippers in instances where ‘regulatory lag’ is occurring or is possible. This article examines the legal implications of these lags for these parties, including an examination of their potential legal obligations and liabilities.

We discuss the transition between ballistic and diffusive regimes and the magnetic horizon of CR sources, showing how magnetic fields of a few nG could modify the shape of the GZK feature. Such fields would roughly be in equipartition with the extragalactic CRs, and could build through the resonant growth of waves within the lifetime of the universe.

We show that the efficiency of the association of atoms is determined just by the Landau-Zener parameter in addition to the density of the gas. Our approach of pairwise summation of the microscopic binary transition probabilities leads to an intuitive explanation for the observed saturation of the molecular production and recovers all atomic loss curves of C.A.

Observation of electroweak production of W$γ$ with two jets in proton-proton collisions at $\sqrt{s} = $ 13 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2020
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A first observation is presented for the electroweak production of a W boson, a photon, and two jets in proton-proton collisions. The W boson decays are selected by requiring one identified electron or muon and an imbalance in transverse momentum. The two jets are required to have a high dijet mass and a large separation in pseudorapidity. The measurement is based on data collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb$^{-1}$. The observed (expected) significance for this process is 4.9 (4.6) standard deviations. After combining with previously reported CMS results at 8 TeV, the observed (expected) significance is 5.3 (4.8) standard deviations. The cross section for the electroweak W$γ$jj production in a restricted fiducial region is measured as 20.4 $\pm$ 4.5 fb and the total cross section for W$γ$ production in association with 2 jets in the same fiducial region is 108 $\pm$ 16 fb. All results are in good agreement with recent theoretical predictions. Constraints are placed on anomalous quartic gauge couplings in terms of dimension-8 effective field theory operators.

description: As part of the PALADIN project which aims to develop a gamma photon detector with 100 ps FWHM time resolution, 1mm FWHM spatial resolution, 10 % FWHM energy resolution and a detection efficiency of about 90%, this thesis aims to provide an accurate simulation of the proposed detector system and to enable a first analysis of its properties. The new design features a central cube shaped scintillation crystal with its sides in direct optical contact to up to 6 dSiPMs developed by Philips. The goal is to improve on current designs in terms of spatial and temporal resolution, energy resolution and photon detection efficiency. To this end, a GEANT4 (GEometry ANd Tracking) application was developed in this work to simulate the new detector system and produce output of resulting scintillation photon emissions from 511keV annihilation photons interacting with a monolithic LYSO:Ce:Ca (Lutetium Yttrium Oxy-Orthosilicate, co-doped with Cerium and Calcium) scintillation crystal. The goal of the simulations presented in this thesis is to determine whether or not the new detector system can be expected to improve on already existing designs where only one or two DPCs were used for readout. These older designs showed, i.e., varying performance for spatial reconstruction along different directions which was inherent in their asymmetric design. Possible improvements in performance for the 6-sided readout will be studied by first discussing the plausibility of the data and then analyzing a few first results such as the probabilities of various processes, the distribution of detection times for photons, the number of Cherenkov photons produced per event, and the performance of a spatial reconstruction algorithm. The data analysis is performed with a self developed ROOT script.

title: Graphic Interrogation in Psychosocial Research: Deleuze AND Comics AND Middle-aged Men
Creators: name: Chessum, Thierry Jacques Patrick
Publisher: name: The Open University
Year: 2015

description: The assemblage of comics, Deleuzian metaphysics and middle-aged men in the context of psychosocial research is an experiment in the sense that Deleuze advocates for the furtherance of thought. The works of Deleuze and Deleuze and Guattari can allow us, it is suggested, to bring together theoretical problems in comics theory with theoretical problems in psychosocial research and provide us with new insights as to how we might look at visual data qualitatively from participants who agreed to recount episodes of their relationships in graphic narrative form.

Both psychosocial qualitative research and comics theory are new and fast moving fields which offer scope for creative thinking. It is argued in this thesis that the ‘affective’ and ‘visual’ turns, which are having an important impact in the social sciences, corresponds to the expressive function of comics, specially in the autobiographical, memoir and confessional genre.

Having set the theoretical lens with the work of Deleuze and Guattari and some of their commentators, examples from commercially published works are examined in order to relate theory to empirical examination, prior to considering the work submitted by participants.

Lastly, interspersed throughout the text and together as an appendix, I offer my own visual reflections in the comics mode which I believe dialogue with topics in the text, whilst remaining separate activities. That is to say I consciously avoid text or comic being an illustration of one another.

description: Hybrid quantum-classical algorithms have been proposed as a potentially viable application of quantum computers. A particular example - the variational quantum eigensolver, or VQE - is designed to determine a global minimum in an energy landscape specified by a quantum Hamiltonian, which makes it appealing for the needs of quantum chemistry. Experimental realizations have been reported in recent years and theoretical estimates of its efficiency are a subject of intense effort. Here we consider the performance of the VQE technique for a Hubbard-like model describing a one-dimensional chain of fermions with competing nearest- and next-nearest-neighbor interactions. We find that recovering the VQE solution allows one to obtain the correlation function of the ground state consistent with the exact result. We also study the barren plateau phenomenon for the Hamiltonian in question and find that the severity of this effect depends on the encoding of fermions to qubits. Our results are consistent with the current knowledge about the barren plateaus in quantum optimization.

description: This thesis deals with a possible solution for the shortcomings that result from the common approach of offering Open Data, where the corresponding data sets are offered as downloadable files on a website. Instead, Open Data producers could offer its data via RESTful web services which conform with OData Version 4, an emerging international standard for REST services. This way, one generic client application could be built, which could enable querying and viewing the exposed data and its data model, without needing to download a file or discovering the data model on your own. By using REST services, also other shortcomings of the mentioned approach could be eliminated. In this thesis, prototypes of both an OData Version 4 compliant RESTful web service and a generic client application were implemented in order to show, that such a constellation is feasible. The generic client application has also been tested successfully against other OData Version 4 compliant REST services. Additionally, a questionnaire on OData has been conducted with domain experts. The domain experts confirmed, that OData supports/enables the building of generic client applications for accessing and querying data published via such interfaces.

Los resultados indican que el numero de hojas, altura y materia seca a los 21, 28 y 35 dias despues de nacidas fue menor en las plantulas sembradas en el sustrato comercial que en los otros dos sustratos (p.05). Similarmente, en el segundo experimento las plantulas sembradas en el sustrato comercial tenian menor altura a los 4, 8 y 12 dias despues del trasplante (DDT) que en los otros dos sustratos (p.05). Se presentaron diferencias (p.05) en la altura de las plantulas a los 4, 8 y 12 DDT, entre el control (no aplicacidn de boro) y las demas dosis, indicando que el rango critico de aplicacidn de boro se encuentra entre 0 y 0.13 mg B/planta. Se sugiere la realizacidn de estudios adicionales para conocer el nivel optimo de aplicacidn de boro, dentro del rango mencionado, a plantulas de lechosa con la finalidad de maximizar la eficiencia en el uso del micronutriente.
title: When Public Relations and Particle Physics Collide: An Ethnographically Informed Account of Life in the CERN Communications Group
Creators: name: Dorey, Jamie

description: This thesis explores how ‘big science’ becomes public within an era of digital scholarship and evolving professional practices. Focusing on research conducted at CERN, I explore the strategic approaches and operational principles and practices of communication professionals and researchers working in High-Energy Physics. A review of current research into the dissemination of scientific information in the digital age shows a dearth of empirical studies that explore the role of communication professionals within scientific organisations. I argue that communication professionals within scientific organisations play an important intermediary role between scientists, external media professionals and publics, often being the first to mediate information for audiences beyond academia. Such groups, therefore, should be explored in order to understand the role they play in mediating science for the contemporary public sphere. This requires that some account be taken of the context within which the communication is produced. At CERN this includes issues of openness and transparency, organisational structures, whilst also taking account of the role of technology in mediating information. A mixed methods approach was used, combining document analysis with ethnographic observations and semi-structured interviews to create eight detailed case studies. In my analysis I argue that scientific public relations is integral to the process of mediation, yet has so far been unrepresented within it. This thesis contributes to a wider understanding of the role organisation plays in the production of High-Energy Physics communication, noting the importance of timing in relation to openness and proposing a methodological approach for the continued research of communications groups in other scientific organisations. Furthermore, this thesis has demonstrated that digital scholarly practices are yet to be fully realised. Instead, a muddled culture of practices exists across CERN, with multiple analogue and digital tools used by individuals and groups working in distinctly separate ways. Overall, the thesis adds to the growing discussion in a number of fields, including the role of scientific public relations in the process of mediation of scientific information and how digital scholarly practices are enacted within a ‘big science’ project.

description: The dynamically triangulated random surface (DTRS) approach to Euclidean quantum gravity in two dimensions is considered for the case of the elemental building blocks being quadrangles instead of the usually used triangles. The well-known algorithmic tools for treating dynamical triangulations in a Monte Carlo simulation are adapted to the problem of these dynamical quadrangulations. The thus defined ensemble of 4-valent graphs is appropriate for coupling to it the 6- and 8-vertex models of statistical mechanics. Using a series of extensive Monte Carlo simulations and accompanying finite-size scaling analyses, we investigate the critical behaviour of the 6-vertex F model coupled to the ensemble of dynamical quadrangulations and determine the matter related as well as the graph related critical exponents of the model.

description: In this paper, we study a relativistic quantum dynamics of spin-$0$ scalar particle interacts with scalar potential in the presence of a uniform magnetic field and quantum flux in the background of Kaluza-Klein theory (KKT). We solve Klein-Gordon equation in the considered framework and analyze the relativistic analogue of the Aharonov-Bohm effect for bound states. We show that the energy levels depend on the global parameters characterizing the space-time, the scalar potential and the magnetic field which break their degeneracy.

Isolated ginsenosides aPPD and aPPT induced cytochrome P450 1 A 1 mRNA expression
Creators: name: Zhao, Yang
Publisher: name: University of British Columbia
Year: 2010

description: Introduction: Ginseng is commonly used in herbal preparations for traditional Chinese medicine. It contains over twenty ginsenosides amongst which aglycon protopanaxadiol (aPPD) and aglycon protopanaxatriol (aPPT) have been shown to be the primary circulating metabolites with potent medicinal properties. To evaluate the prospect of metabolic drug interactions the effects of aPPD and aPPT on expression and function of human cytochromes P450 CYP1A1 was assessed. Methods: Real Time RT-PCR and western blotting were used to measure CYP1A1 mRNA and protein expression in human HepG-2 and Caco-2 cells treated with aPPD or aPPT for 12 and 24 hours. A P450-CYP1A1 assay was used to measure CYP1A1 activity. Gudluc 1.1 was luciferase labeled and used as the CYP1A1 promoter constructs. It was co-transfected with Ary1 hydrocarbon receptor (AhR) and pRL-TK (control) plasmids to examine CYP1A1 mRNA induction via AhR. pGL3B-CYP1A1 plasmid was constructed containing longer CYP1A1 promoter sequence (-2425, +352) than Gudluc 1.1 (-1301, -819) and used to investigate the induction mechanism outside of AhR pathway. Results: There was a dose-dependent induction of CYP1A1 mRNA expression in both HepG-2 and Caco-2 cells dosed for 12h and 24h with either aPPD or aPPT. The result was statistically significant at concentrations of 5 [micro sign]M and above; however, this was not correlated with increased protein levels. P450-Glo[Trade Mark Sign] reporter assay produced a significant increase in CYP1A1 activity only after treatment with 80 and 160 [micro sign]M aPPD. No effects were found at lower concentrations of aPPD and all concentrations of aPPT. Induction of CYP1A1 mRNA by aPPD and aPPT was independent of AhR activation. Functional sequence was outside of the region from -2425 to +352. Conclusions: Overall, our results suggest that aPPD and aPPT exert a significant inductive effect on CYP1A1 mRNA level, while also activating CYP1A1 protein activity only with high concentrations of aPPD. This induction of mRNA level is not likely to be regulated by AhR.

description: We show that near densest-packing the perturbations of the HCP structure yield higher entropy than perturbations of any other densest packing. The difference between the various structures shows up in the correlations between motions of nearest neighbors. In the HCP structure random motion of each sphere impinges slightly less on the motion of its nearest neighbors than in the other structures.

description: This study evaluates the production, imports, and exports tendencies for the winter tomato market of the United States, Puerto Rico, and México during two periods. The first period, called pre-NAFTA is defined from 1990 until 1993, three years before the North American Free Trade Agreement (NAFTA) came into effect. The second period, defined as post-NAFTA, covers four years, from 1994 to 1997, the first years after theNAFTA came into effect. It is estimated that an average of 710,715 pounds of fresh tomatoes are imported by the U.S. from the Mexico during the pre-NAFTA period. During the first four years of NAFTA the U.S. fresh tomato imports from Mexico averaged 1,276,134 pounds. An average increase of 65% in imports of fresh tomatoes from Mexico was calculated, causing Florida tomato producers to be concerned of the implication of this agreement. In P.R., most of the tomato production is during the winter season, with exports of 60% to the U.S. During other seasons, P.R. imports 90% of fresh tomatoes from the U.S. In the pre-NAFTA period, P.R_imported an average of 178,958 from U.S., and 180,803 during the post-NAFTA period. These averages represent an increase of 1.03%, which is not a significant change in the tomato imports' tendencies. For the studied periods, Mexico has not had a direct significant effect on the imports of fresh tomatoes in P.R. This study also considers the possible effects on the production of fresh tomatoes if the Cuban embargo is lifted.

description: In the context of astrophysical dynamos we illustrate that the no-cosines flow, with zero mean helicity, can drive fast dynamo action and study the dynamo's mode of operation during both the linear and non-linear saturation regime: It turns out that in addition to a high growth rate in the linear regime, the dynamo saturates at a level significantly higher than normal turbulent dynamos, namely at exact equipartition when the magnetic Prandtl number is on the order of unity. Visualization of the magnetic and velocity fields at saturation will help us to understand some of the aspects of the non-linear dynamo problem.

description: The dynamics of a polymer ring enclosing a constant {\sl algebraic} area is studied. The constraint of a constant area is found to couple the dynamics of the two Cartesian components of the position vector of the polymer ring through the Lagrange multiplier function which is time dependent. The time dependence of the Lagrange multiplier is evaluated in a closed form both at short and long times. At long times, the time dependence is weak, and is mainly governed by the inverse of the first mode of the area. The presence of the constraint changes the nature of the relaxation of the internal modes. The time correlation of the position vectors of the ring is found to be dominated by the first Rouse mode which does not relax even at very long times. The mean square displacement of the radius vector is found to be diffusive, which is associated with the rotational diffusion of the ring.
