description: This report provides a practical and evidence-based review of prospect research in Canadian philanthropy and how its value and Return on Investment (ROI) is perceived in charitable organisations, both large and small. A key finding is prospect research showed both short and long-term value, during times of change, and for strategic, major gift and large campaigns. There is a clear connection between effective use of digital technologies and organisational fundraising capacity.
The target audience for the report are people who engage in decisions of this nature daily: board members, CEOs, and directors. We believe that this research report will also be valuable to a much wider audience of professionals who engage in philanthropic, fundraising, and capital campaign projects.
Data for this report was collected between April and July 2021 through a combination of fieldwork and desktop research. Fifteen non-profit sector leaders from across Canada were invited to participate and in-depth interviews were conducted with all those who agreed. Contributors came from various sectors and sizes of organisations: higher education, healthcare, arts, Indigenous organisations, faith-based institutions, and philanthropic hi-tech. A survey was also conducted of 25 Global Philanthropic Senior Consultants across Canada about their client engagements and prospect research component in fundraising projects. Desktop and open-source research and a review of scholarly literature on the topic was also conducted to review the scope of scholarly publications on the topic. Quotes and opinions from industry leaders are provided as is from their interviews.
Il poema sinfonico nell'opera giovanile di Arnold Schoenberg

Subjects: L-ART/07 Musicologia e storia della musica

description: Gli esordi di Arnold Schoenberg sono da qualche tempo al centro dell'interesse della ricerca musicologica. La rinnovata attenzione verso le opere giovanili del compositore viennese è legata a doppio filo ai motivi di un nuovo dibattito storiografico sulla Wiener Schule. Di recente, Andreas Meyer e Ullrich Scheideler hanno puntato il dito contro la tendenza ad assumere posizioni apologetiche da parte di una passata storiografia, che per la preoccupazione di legittimare l'opera schoenberghiana ha finito spesso per appiattirsi sulla poetica del compositore e per confondersi ipso facto con la critica militante.
Nel quadro attuale, si può dire che gli studi su Schoenberg si siano affrancati dalla sua ingombrante autorità . Decisiva, in questo processo di emancipazione, è stata la scelta di rimettere in discussione l'immagine autoriale schoenberghiana, a partire dalla riconsiderazione dell'evoluzione artistica del compositore.
Un contributo considerevole alla definizione di questo nuovo quadro potrà  venire da un attento esame delle opere giovanili, segnatamente del periodo anteriore a Verklaerte Nacht op. 4 (1899).

description: We study a flat connection defined on the open-closed deformation space of open string mirror symmetry for type II compactifications on Calabi-Yau threefolds with D-branes. We use flatness and integrability conditions to define distinguished flat coordinates and the superpotential function at an arbitrary point in the open-closed deformation space. Integrability conditions are given for concrete deformation spaces with several closed and open string deformations. We study explicit examples for expansions around different limit points, including orbifold Gromov-Witten invariants, and brane configurations with several brane moduli. In particular, the latter case covers stacks of parallel branes with non-Abelian symmetry.

description: Die vorliegende Arbeit umreißt die Verwertbarkeit zweier pflanzlicher O-Methyltransferasen (O-MTs), PFOMT und SOMT-2, der Klassen I und II für die biokatalytische Methylierung in polyphenolischen Verbindungen verbreiteter Strukturmotive. Die PFOMT wurde mithilfe der isothermen Titrationskalorimetrie sowie der Lösung einer Kristallstruktur des apo-Enzyms biophysikalisch charakterisiert. In vivo Studien der SOMT-2 zeigten die Methylierung von Flavonoiden und Stilbenen an der 4'-Position. Es wurde gezeigt, dass die Aktivität der PFOMT durch Variation von pH-Wert und Magnesium so weit moduliert werden kann, dass vorher unbeschriebene Methylierungen von nicht-catecholen Motiven möglich sind. Zuletzt wurden 15 Flavonoide mit unterschiedlichen Substitutionsmustern am B-Ring mittels Tandem-Massenspektrometrie (MS/MS) durch collision induced dissociation (HCD) und higher-energy collisional dissociation (CID) charakterisiert.
description: The present study outlines the useability of two plant O-methyl transferases (O-MTs), phenylpropanoid and flavonoid O-methyl transferase (PFOMT) and soy O-methyl transferase (SOMT-2), of classes I and II for the biocatalytic methylation of common structural motifs encountered throughout the group of in plant polyphenolic compounds. PFOMT was biophysically characterized through and the solution of a novel crystal structure of its apo-form. In vivo studies using SOMT-2 showed its capability to methylate flavonoids and stilbenes at the 4'-position. It was demonstrated that the activity of class I plant O-MT, PFOMT, could be modulated by pH and magnesium concentration to achieve previously unobserved methylations of non-catecholic moieties. Additionally, a systematic grid of 15 flavonoids with different substitutions at the B-ring was characterized by tandem mass-spectrometry (MS/MS) studies through higher-energy collisional dissociation (HCD) and collision induced dissociation (CID).

description: Die Ösophagusmanometrie ist eine etablierte Untersuchungsmethode in der Diagnostik und Therapiekontrolle von Erkrankungen der Speiseröhre im Erwachsenenalter und wird bei Kindern nur in wenigen Zentren durchgeführt. Bisher existieren keine publizierten Ergebnisse der Gasperfusionsmanometrie des Ösophagus im Kindesalter. In der vorliegenden Arbeit wurden 176 manometrische Untersuchungen des Ösophagus hinsichtlich der Eignung und des Einsatzes dieser Methode im Kindesalter sowie deren Stellenwert in der Diagnostik und Kontrolle eines pathologischen gastroösophagealen Refluxes analysiert. Dabei konnten die Eignung der Heliumperfusionsmanometrie und die Besonderheiten der Anwendung bei Kindern herausgearbeitet werden. Die Auswertung der manometrischen Parameter ergab eine statistisch signifikante Abnahme des unteren Ösophagussphinkter (UÖS)-Druckes mit zunehmender Symptomatik. Die Risikoquoten für den Nachweis eines pathologischen Befundes lagen bei der Manometrie gegenüber der pH-Metrie und Refluxsonographie bei Kindern mit gleicher Symptomatik höher. Es konnte gezeigt werden, dass die Anwendung der Ösophagusmanometrie in der Diagnostik eines pathologischen gastroösphagealen Refluxes auch im Kindesalter sinnvoll ist.
description: The manometry of the esophagus is an established investigation method in the diagnosis and therapy of esophagus diseases in adults. In children it is used only in a few medical centers. There have been no published results of gas-perfusion manometry of the esophagus in childhood yet. 176 manometric investigations of the esophagus were analysed concerning the suitability and capability of this method in childhood and to determine the significance in the diagnosis and therapy of a gastro-esophageal reflux disease. It was found that the helium-perfused system is a suitable method in children. There was a statistically significant reduce of the lower esophageal sphincter pressure (LES) with increased clinical symptoms. The odds ratio for the evidence of a pathologic diagnostic finding was higher in manometry in comparison to pH-metry and reflux ultrasound in children with the same clinical symptoms. It was shown that the the esophegeal manometry is useful in the diagnosis of a pathologic gastro-esophageal reflux disease in childhood.

description: Mit der Durchführung von registrierenden Kontaktexperimenten mit Kraft- und Eindringtiefenauflösungen im Bereich von 10⁻⁶ N und 10⁻⁹ m können versetzungsfreie Bereiche von Kristallen lokal mit hohen Spannungen belastet werden. Dadurch ist es möglich den Prozess der homogenen Versetzungsnukleation zu aktivieren, der sich beim Eindruckversuch durch einen plötzlichen in der Literatur als Pop-In-Effekt bezeichneten Eindringtiefensprung äußert. In dieser Arbeit wurde die Abhängigkeit dieses Prozesses von der Kristallorientierung untersucht, wozu ein Modell erarbeitet wurde, welches der Richtungsabhängigkeit der elastischen und plastischen Materialeigenschaften von kubischen Systemen beim Eindruckexperiment Rechnung trägt. Es konnte gezeigt werden, dass dieses Modell die durchgeführten Experimente an GaAs in den Orientierungen (001), (111), (1̅ 1̅ 1̅ ) und (101) sowohl qualitativ als auch quantitativ beschreibt. Die erzeugten Defektstrukturen, die kurz nach Einleitung des Pop-In-Effektes vorliegen, wurden transmissionselektronenmikroskopisch abgebildet und konnten mit den kontaktinduzierten Spannungsverteilungen begründet werden. Es wurden Indizien gefunden, wonach die Versetzungsbewegung in GaAs unter den vorhandenen Versuchsbedingungen (Raumtemperatur, hoher Druck) durch einen Mechanismus erfolgt, wie er bisher durch Untersuchung mit konventionellen Techniken (z.B. einaxialer Zug), die höhere Temperaturen erfordern, nicht beobachtet wurde.
description: Depth sensitive hardness measurements with force and displacement resolutions of 10⁻⁶ N and 10⁻⁹ m (range of nanoindentation) allow the producing of localised high stresses in dislocation free regions. This makes it possible to activate the process of homogeneous dislocation nucleation. In the measurement data (load versus displacement) it is characterized by a clear and sudden displacement jump, which is called "pop in effect" in literature. In the present work the anisotropy of this effect was investigated. To do this an analytical model was developed to describe the elastic contact with respect to the anisotropic elastic and plastic material properties of cubic systems. It was shown, that this model describes qualitatively and quantitatively the indentation experiments on GaAs wafers in (001), (111), (1̅ 1̅ 1̅) and (101) surface orientations. The produced defect structures (dislocation rosettes) in the state near the "pop in effect" were imaged by transmission electron microscopy for all surfaces orientations. The structure of the dislocation rosettes were explained by the stress distribution of the shear stresses acting on the slip systems. It was found, that the mechanism of dislocation movement at the present experimental conditions (room temperature, high stresses) is different from that, which is observably with conventional investigation techniques, which require higher temperatures (more than about 450 °C).
'How this holiday makes a difference': the language of environment and the environment of nature in a cross-cultural study of ecotourism

description: Partendo dal presupposto che le differenze culturali spesso costituiscono una fonte potenziale di problematiche traduttive, questo contributo mira a evidenziare le differenze che emergono sul piano linguistico, a livello lessicale, ma soprattutto fraseologico, in seguito a variegati orientamenti culturali che agiscono come filtri.
Il linguaggio specialistico analizzato riguarda una nicchia particolare del mercato del turismo, ossia l’ecoturismo, che sta conquistando un terreno sempre più vasto in seguito ad una maggiore attenzione rivolta nei confronti di tematiche attuali, come quelle di impatto ambientale. Abbracciando una prospettiva interculturale, il lavoro indaga il diverso approccio che la cultura americana, britannica e italiana mostrano nei confronti dell’ambiente e della natura, ipotizzate, in questo contesto, come categorie ideologiche del linguaggio utilizzate per la promozione dell’ecoturismo.
È centrale allo studio la classificazione operata negli anni da Hall (1976; 1983; 1990) fra culture verosimilmente più orientate verso il contesto, come quella italiana, e quelle più orientate verso il testo, come quelle americana e britannica. Tale suddivisione comporta una serie di diverse tendenze, soprattutto comunicative, che caratterizzano le culture e quindi anche le lingue. Per esempio, ad una maggiore espressività dell’Italiano sembrerebbe corrispondere una comunicazione più informativa dell’Inglese britannico.
I dati analizzati derivano da un corpus comparabile assemblato ad hoc che include testi scaricati da siti web ufficiali dell’ecoturismo. L’analisi parte da un approccio quantitativo basato sulla Corpus Linguistics, avvalendosi della teoria fraseologica che risulta rilevante anche a livello traduttivo. Emergono notevoli discrepanze fra le tre lingue nell’uso dei termini chiave del discorso.
I risultati dell’indagine rilevano differenze di lessicalizzazione dei concetti fondamentali che sono parte di altrettanto diverse scelte fraseologiche nelle tre lingue. Il lavoro conferma l’importanza di come la pratica traduttiva possa trarre vantaggi da uno studio sistematico delle multiword units nelle lingue e culture.

description: Studies of market integration show that price changes are transmitted spatially through arbitrage. Transmission across differentiated agricultural products is important to investigate, but it has not been explored given its complexities for assessment. Using data from Australian cattle markets, we examine the dynamics of Meat Standards Australia price premium transmission between states. An impulse response function analysis using Bayesian vector autoregression with sign restriction identification shows that shocks to prices and price premiums are partially transmitted contemporaneously between markets and it takes several weeks to complete transmission. In addition, we find an asymmetry of price and price premium shocks originating in Southern Queensland that have an inverse immediate impact in New South Wales, and take months to transmit the usual price response. This outcome may be explained by differences in cattle availability in each state, which can be related to forage availability due to weather conditions. Based on these results, producers can forecast fluctuations on price premiums and adjust their cattle supply accordingly.

description: Die Selektine spielen bei Entzündungsprozessen eine bedeutende Rolle. Zur Untersuchung der Rezeptor-Liganden-Wechselwirkungen wurde die Chorioallantoismembran (CAM) des Hühnerembryos als in-vivo Modell verwendet. Nach vielen Modifizierungen der ursprünglichen Technik wurden ausreichend hohe Überlebensraten der Embryonen erzielt und eine neue Injektionstechnik entwickelt. Es wurden FITC-Partikel (Fluoreszierende Carboxylierte Mikropartikel), CHO-Zellen (Chinesische Hamsteovar-zellen), CHOE-Zellen ( + E-Selektin), U937-Zellen, mit P-Selektin beschichtete FITC-Partikel sowie hühnereigene Leukozyten injiziert und deren intravasales Verhalten kinematografisch verfolgt. CHO- / CHOE- und U937-Zellen eigneten sich aufgrund der starken Adhärenz der Zellen nicht für differenzierte Geschwindigkeitsbestimmungen. Es konnte gezeigt werden, daß sich die mit P-Selektin beschichteten FITC-Partikel bereits ab dem 7. Entwicklungstag signifikant langsamer bewegten als die Kontrollpartikel. Adulte Hühnerleukozyten ähnelten in ihrem intravasalen Verhalten den FITC-Partikeln und sind für in-vivo Untersuchungen gleichfalls gut geeignet. Der erstellte Fotoatlas gibt eine Übersicht über die Entwicklungsstadien der Embryonen und ordnet jedem Stadium von Hamburger-Hamilton die zugehörige CAM bei der Kultivierung in der "Spiegeleikultur" zu.
description: The selectins play an important role in inflammatory processes. To investigate their receptorligand-interactions the chorioallantoismembrane (CAM) of the chick embryo was used as invivo modell. After many modifications there was aimed a sufficient survival rate of the embryos and a new technique of injection was developed. We injected FITC-particles (fluorescent carboxylated microspheres), CHO-cells (chinese hamsterovar-cells), CHOE-cells (+E-selectin), U 937-cells, FITC-particles covered with P-selectin as well as chick leukocytes and investigated their intravasal movement. Because of their adhesion CHO- / CHOE- and U937-cells were less qualified for measurements of their velocities. It could be shown that the particles covered with P-selectin moved significant slowlier already from the 7 th day of incubation than the particles of the control group. Adult chick leukocytes resembled the FITC-particles in their intravasal movement and are suitable for in-vivo investigations. The photo atlas presented in this work shows the stages of the embryos and assigns to every stage of Hamburger-Hamilton the accompanying CAM during cultivation in a shell-less culture.

description: Use of the stochastic Galerkin finite element methods leads to large systems of linear equations obtained by the discretization of tensor product solution spaces along their spatial and stochastic dimensions. These systems are typically solved iteratively by a Krylov subspace method. We propose a preconditioner which takes an advantage of the recursive hierarchy in the structure of the global matrices. In particular, the matrices posses a recursive hierarchical two-by-two structure, with one of the submatrices block diagonal. Each one of the diagonal blocks in this submatrix is closely related to the deterministic mean-value problem, and the action of its inverse is in the implementation approximated by inner loops of Krylov iterations. Thus our hierarchical Schur complement preconditioner combines, on each level in the approximation of the hierarchical structure of the global matrix, the idea of Schur complement with loops for a number of mutually independent inner Krylov iterations, and several matrix-vector multiplications for the off-diagonal blocks. Neither the global matrix, nor the matrix of the preconditioner need to be formed explicitly. The ingredients include only the number of stiffness matrices from the truncated Karhunen-Loève expansion and a good preconditioned for the mean-value deterministic problem. We provide a condition number bound for a model elliptic problem and the performance of the method is illustrated by numerical experiments.

Spatial and temporal details of spontaneous cortical activity provide insights into functions in the adult and developing brain
Creators: name: McVea, David
Publisher: name: University of British Columbia
Year: 2013

description: While the body rests, the mind remains active. In fact, the brain exhibits a rich pattern of structured activity despite having few immediate sensory or motor tasks. During infancy, this brain activity appears tailored to assist in the maturation of neural systems. In the adult, it influences memory consolidation and maintenance of synaptic connections. In this thesis, I address these differences by using voltage-sensitive dye imaging to record spontaneous cortical activity in rodents during development and adulthood. In the adult, I examine slow-wave activity, a key form of spontaneous activity. I show that functionally related regions of the cortex activate synchronously, forming a core set of structures that underlie spontaneous activation. I also show that sensory connections shape the patterns of this activity. These effects hold true in the quietly awake mouse, to a lesser extent. These findings are consistent with an active role for slow-wave activity in the maintenance of cortical connections. In the infant, I examine a dominant form of brain activity, the spindle burst. This pattern of activity follows spontaneous sensory inputs generated by the developing sensory systems, including small twitches in the limbs and tail. It is generally thought to remain localized with the appropriate cortical sensory system, but using wide-field imaging, I show it spreads medially across the cortex. This suggests a potential role in the maturation of connections between sensory and motor regions. I explored this possibility more closely by recording activity in early life from the whisker system of the rat. In the adult, connections exist between the sensory and motor regions of the whisker system. To gain insight into whether the spontaneous activation of these systems contributed to their development, I compared the activity evoked by stimulation to the spontaneous activation of these systems. I found synchronized spontaneous activation of motor and sensory areas that were not yet functionally connected. This suggests that other structures synchronize these areas to promote the maturation of connections between them. Overall, this work reveals details about spontaneous activity that provide clues to why the brain devotes time and energy to activity disconnected from the outside world.

description: Il nucleo più antico del Pactus legis Salicaesi si può, forse, identificare con un atto unilaterale del potere romano, ossia con una lex data. La legge salica proporrebbe, allora, un compromesso tra il costume gentilizio dei Franchi, fondato sulla vendetta, e le esigenze dell’ordine pubblico romano. Attraverso il ricorso a compensazioni determinate da una tariffa o ad altri strumenti di composizione delle liti, il governo imperiale intendeva costringere i suoi laeti barbari a trovare soluzioni pacifiche alle loro controversie.

The most ancient nucleus of Pactus legis Salicae can be perhaps identified with an unilateral decision of Roman power that is with a lex data. The lex Salica, in the opinion of Jean-Pierre Poly, suggests a compromise between tribal traditions of Franks, based on revenge, and Roman order. Auctually the Roman government wanted its barbarian laeti to settle without bloodshed their quarrels, using fixed fines.

description: Technologies like improved breeds of dairy cows and improved forages have the potential to significantly increase dairy cow productivity and farmers’ profits in developing countries. However, adoption of such technologies has been low in Ethiopia, despite numerous efforts to disseminate the technologies in the past. Some studies argue that adoption of technologies is low because welfare effects of the technologies could be insignificant or negative to certain groups of farmers. This article employed propensity score matching and inverse probability weighting estimator with regression adjustment to examine the difference in household nutrition and income between adopters and nonadopters of dairy technologies in rural Ethiopia. We find that adoption of cross-bred dairy cows and improved forages increases household nutrition and income. The significant household nutrition and income impact for adopters support the notion that many Ethiopian smallholders have not adopted dairy technologies because adopters and nonadopters of dairy technologies have inherent differences in welfare outcome potentials. The results suggest that interventions that enhance access to farm resources and address barriers to input and output value chains could improve adoption of dairy technologies.

description: A high energy ep collider, such as the proposed LHeC, possesses the unique facility of permitting direct measurement of the HWW coupling without contamination from the HZZ coupling. At such a machine, the fusion of two W bosons through the HWW vertex would give rise to typical charged current (CC) events accompanied by a Higgs boson. We demonstrate that azimuthal angle correlations between the observable CC final states could then be a sensitive probe of the nature of the HWW vertex and hence of the CP properties of the Higgs boson.

The dérive was an essential part of psychogeographic practice, emphasizing observation, spirit, emotion, and experience in response to what Debord deemed a memetic society of consumption and distraction. Today, experimental and affective geographers wander down paths laid by the psychogeographers, similarly exploring the affective import of space. Cartography has served as an important medium for those interested in space; and offered a tool for geographers and artists alike to make relational sense of place and space. Still, cartographies, even those that emphasize subjectivity and abstraction, are largely visual. Soundscapes and sound mappings offer rich potential to expand sensory cartography and bridge aural and visual spatial epistemologies; but, sound mapping's emphasis on high fidelity recordings, tied directly to precise geographic coordinates leaves room for abstraction and musicality in sonic cartography. Building on decades of audio visually inspired work, this thesis examines new ways of narrating space through sonic experimentation, provides a performative protocol for data collection, and describes a resulting computational system for mapping visual to sonic spaces. The output is a site specific and autobiographical work that takes the ‘daily stroll ’as its central input. These daily strolls are formalized as data collection: daily video recordings were captured of Shadyside (Pittsburgh, PA, USA) over the course of a six-month period. Their visual streams are segmented and mapped to audible parameters, ultimately creating a generative composition that tells an evocative story of place over time. In so doing, the work proposes and demonstrates mapping as composition and composition as a mapping and tugs at the affective and performative potentials of sound mapping to generate new spatial imaginaries. Reflecting on the work opens further possibilities for ‘hearing ’visual space: from assistive wayfinding technologies to urban planning tools, there remain rich potential applications for sonifiying the built environment.

description: In this paper we consider an overlapping generation model in which people, born in two different countries, decide where to spend their working period of life, and where to retire after it. The two countries differ in technology and quality of life. The "northern" country, N, is more productive, while in the "southern" country, S, people enjoy a better quality of life. Locational preferences are influenced not only by "objective" criteria –like climate, pollution, congestion–, but also by "cultural" factors. Thus we assume that people prefer to live in their country of origin. footnote It will be shown that, under plausible assumptions, locational decisions cause migration from S to N, but the importance of this phenomenon depends on how locational preferences are made endogenous. In Section 2 we describe the production side of our model, and in Section 3 its consumption side. We then examine the influence of locational preferences that are taken as exogenous, in Section 4, and made endogenous, at least for their subjective component, in Section 5.

description: In this paper we study the inverse problem of determining the residual stress in Man's model using tomographic data. Theoretically, the tomographic data is obtained at zero approximation of geometrical optics for Man's residual stress model. For compressional waves, the inverse problem is equivalent to the problem of inverting the longitudinal ray transform of a symmetric tensor field. For shear waves, the inverse problem, after the linearization, leads to another integral geometry operator which is called the mixed ray transform. Under some restrictions on coefficients, we are able to prove the uniqueness results in these two cases.

description: The consequences of the adoption of quality standards on the extent of market coverage is investigated by modelling a game between regulator and low-quality firm in a vertically differentiated duopoly. The game has a unique equilibrium in the most part of the parameter range. There exists a non-negligible range where the game has no equilibrium in pure strategies. This result questions the feasibility of MQS regulation when firms endogenously determine market coverage.

description: Bounds on anomalous dimensions of scalar operators in 4d superconformal field theory are explored through perturbative viewpoint. Following the recent work of Green and Shih, in which a conjecture involved this issue is verified at the NLO, we consider the NNLO corrections to the bounds, which are important in some situations and can be divided into two cases where $\mathcal{O}(λ^{4})$ or $\mathcal{O}(y^2)$ effects dominate respectively. In the former case, we find that the conjecture is maintained at NNLO, while in the later case, the statement still holds due to the null corrections arising from $\mathcal{O}(y^{2})$.

description: Numerical analysis of time-integration algorithms has been applying advanced algebraic techniques for more than fourty years. An explicit description of the group of characters in the Butcher-Connes-Kreimer Hopf algebra first appeared in Butcher's work on composition of integration methods in 1972. In more recent years, the analysis of structure preserving algorithms, geometric integration techniques and integration algorithms on manifolds have motivated the incorporation of other algebraic structures in numerical analysis. In this paper we will survey structures that have found applications within these areas. This includes pre-Lie structures for the geometry of flat and torsion free connections appearing in the analysis of numerical flows on vector spaces. The much more recent post-Lie and D-algebras appear in the analysis of flows on manifolds with flat connections with constant torsion. Dynkin and Eulerian idempotents appear in the analysis of non-autonomous flows and in backward error analysis. Non-commutative Bell polynomials and a non-commutative Faà di Bruno Hopf algebra are other examples of structures appearing naturally in the numerical analysis of integration on manifolds.

description: Im Laufe des anaeroben Stoffwechsel des gram- Bakteriums Escherichia coli kann im Zuge der gemischten Säure-Gärung Pyruvat zu Formiat durch die Aktivität der Pyruvat-Formiat-Lyase (PflB) oxidiert werden. Da eine Anhäufung von Formiat im Cytoplasma zu einer Entkopplung des Protonen-Gradienten führen kann, muss ein Translokationssystem für Formiat existieren. 1994 konnte von Suppmann und Sawers das Formiat Kanal Protein FocA als potentieller Translokator identifiziert werden. Mit Hilfe von gerichteter Mutagenese wurden verschiedene Varianten von FocA überproduziert, gereinigt und mittels CD-Spektroskopie sowie Blue Native Page analysiert. Es konnten verschiedene Aminosäuren identifiziert werden, welche an der Translokation von Formiat beteiligt sind. Mit Hilfe von in vivo (bacterial two hybrid system) und in vitro (pull down Analysen, Far Western Blot Analyse) Untersuchungen konnte eine Interaktion zwischen dem Membranprotein FocA und dem cytosolischen Protein PflB nachgewiesen werden.
description: During mixed acid fermentation in Escherichia coli pyruvate is converted to formate and acethyl-CoA by the enzyme pyruvate formate lyase (PflB). Due to the fact an accumulation of formate in the cell would lead to an uncoupling of the proton motive force, a translocation system for formate must exist. 1994 Suppmann and Sawers were able to identify the formate channel protein FocA as a potential formate translocator. By using site-directed mutagenesis different variants of FocA were overproduced, purified and analyzed by CD-spetroscopy and blue native page analysis. The influence of single aminoacids in the formate translocation could have been shown. The cytosoloic protein PflB was identified as interaction partner of the membrane protein FocA by in vivo (bacterial two hybrid system) and in vitro (pull down analysis, far western blot analysis) methods.
