description: two new species of genus Piper L. from Madagascar: Piper malgassicum Papini, Palchetti, M. Gori & Rota Nodari and Piper tsarasotrae Papini, Palchetti, M. Gori & Rota Nodari, were analyzed to investigate their phylogenetic position and evolutionary history. Both plastidial and nuclear markers were used for sequencing. The plastidial markers (ndhF and trnL intron) showed a close relationship between the two species with respect to the other species of Piper. Both species appeared phylogenetically related to the African P. guineense and the Malagasian/Mascarenhas endemic P. borbonense. The nuclear marker (G3pdh) amplification produced two separate sets of sequences: “long” sequences and “short” sequences, characterized by some long deletions. Analyzing together the nuclear sequences, we observed that the “long” sequence of P. tsarasotrae had a stricter relationship to the African accessions of P. guineense, while the accession of P. malgassicum was more strictly related to P. borbonense. On the contrary both “short” sequences of P. malgassicum and P. tsaratsotrae resulted phylogenetically related to Asian accessions and more distantly related to the formerly cited species. This unexpected result was tentatively explained with a more ancient hybridization event between an ancestor of P. malgassicum and P. tsarasotrae (and possibly P. borbonense) and an Asian species of Piper. The Asian contribution would have produced the ancestors carrying the “short” sequences. A more recent hybridization event would have led to the separation of P. malgassicum from P. tsarasotrae with an African pollen-derived genome contribution from P. guineense or, more probably, an ancestor thereof, to an ancestor of P. tsarasotrae. The chromosome numbers of P. tsarasotrae (2n = about 38) and P. malgassicum (2n = about 46), were more similar to the Asian species than to the American species. Unfortunately, no chromosome number of the African species P. guineense is currently available, to compare the chromosomal numbers.

Financing the Royal Navy,1905-1914 : Sound finance in the Dreadnought era
Creators: name: Campbell, Todd Christopher
Publisher: name: University of British Columbia
Year: 2009

description: The theory of sound finance which dominated British fiscal ideology in the Victorian and Edwardian periods hindered Britain's ability to respond decisively to the German challenge to Royal Navy supremacy from 1905-1908, as the then Chancellor of the Exchequer, Asquith, concentrated on reducing the National Debt and retrenchment of naval expenditure. This was a mistake as it encouraged Germany's naval ambitions. The Government, constrained by the ideology of sound finance, did not realize the enormous resources available to it by shifting the focus of taxation to direct sources of revenue through the income tax and death duties. As Royal Navy supremacy had to be maintained regardless of the cost and the Liberal Government was committed to social reform, a reform of the fiscal system was necessary. Lloyd George fully exploited the fiscal system in his "People's Budget"of 1909, relying heavily on innovations previously introduced by Asquith, and it fulfilled the Government's revenue requirements admirably up to the outbreak of war in 1914. The Liberal Government was able to finance both the supremacy of the Royal Navy and costly social reforms, in the process introducing the era of both modern Government finance and the welfare state in Britain.

description: Galactic globular cluster (GC) stars exhibit abundance patterns which are not shared by their field counterparts, In the framework of the widely accepted "self-enrichment" scenario for GCs, we present a new method to derive the Initial Mass Function (IMF) of the polluter stars, by using the observed O/Na abundance distribution. We focus on NGC 2808, a GC for which the largest sample of O and Na abundance determinations is presently available. We consider two classes of possible "culprits" : massive Asymptotic Giant Branch (AGB) stars (4-9 Msun) and winds of massive stars (WMS) in the mass range 10-100 Msun. We obtain upper limits for the slope of the IMF (assumed to be given by a power-law) of the stars initially more massive than the present turnoff mass. We also derive lower limits for the amount of stellar residues. We find that the polluter IMF had to be much flatter than presently observed IMFs in stellar clusters, in agreement with the results of two other methods for GC IMF determination. Additionaly, we find that the present mass of the GC should be totally dominated by stellar remnants if the polluters were AGB stars, but not so in the case of WMS. We critically analyse the advantages and shortcomings of each potential polluter class, and we find the WMS scenario more attractive.

description: Stressful high temperatures on plants can limit whole-plant function and decrease crop productivity. However, little is known regarding heat stress effects on microtubule cytoskeleton and chromatin in roots from intact plants. Here we studied high temperature effects on cell division, microtubule and chromatin organization patterns in rye root tips from intact plants subjected to 40ºC for 4 h and after different recovery periods (0RT, 7RT, 24 RT). We showed that heat stress induced changes in nuclear morphology as detected by the unusual presence of interphase cells with irregularly shaped nuclei, probably associated with changes in chromosome segregation at anaphase, leading to micronuclei formation as well as changes in the mitotic index. These alterations were associated to differential effects in microtubules organization in both heat-stressed interphase and mitotic cells at 0RT and 7RT. Although no changes in the distribution of H3 phosphorylation of Ser 10 residues on chromatin were found in cells from heat-stressed plants, marked alterations in chromatin DNA methylation patterns were detected. These effects included higher agglutination of 5-methylcytosine domains in both interphase and metaphase cells compared to controls. Taken together these results seem to suggest that alterations in microtubule conformation upon heat stress influences nuclear chromatin organization and cell cycle progression. However, when seedlings recovered from stress (24RT), root tip cells presented microtubule configurations and chromatin organization patterns similar to controls. We conclude that in spite of heat stress markedly altered cell cycle progression and distribution of epigenetic marks, these responses are transient to cope with such stress conditions in the roots.

description: The analysis of singular regions in the NUT solutions carried out in the recent paper (Manko and Ruiz, 2005 Class. Quantum Grav. 22, p.3555) is now extended to the Demianski-Newman vacuum and electrovacuum spacetimes. We show that the effect which produces the NUT parameter in a more general situation remains essentially the same as in the purely NUT solutions: it introduces the semi-infinite singularities of infinite angular momenta and positive or negative masses depending on the interrelations between the parameters; the presence of the electromagnetic field additionally endows the singularities with electric and magnetic charges. The exact formulae describing the mass, charges and angular momentum distributions in the Demianski-Newman solutions are obtained and concise general expressions P_n=(m+iν)(ia)^n, Q_n=(q+ib)(ia)^n for the entire set of the respective Beig-Simon multipole moments are derived. These moments correspond to a unique choice of the integration constant in the expression of the metric function ωwhich is different from the original choice made by Demianski and Newman.

description: Aufstrebende Technologien wie organische Leuchtdioden oder organische Photovoltaik sind angewiesen auf den effizienten Transport von angeregten elektrischen Zuständen, wie beispielsweise Exzitonen. In Pflanzen basiert Exzitontransport auf geordneten Arrangements von Porphyrin-Molekülen. Dieses Konzept kann künstlich angewandt werden, indem solche Moleküle mittels eines metall-organischen Gerüsts (metal-organic framework, MOF) angeordnet werden, was entweder als MOF-Pulver oder in Form eines dünnen Films (surface-anchored metal-organic framework, SURMOF) möglich ist. In dieser Arbeit werden SURMOF-Dünnschicht-Filme untersucht, in welchen Palladium-Porphyrin-Verbindungsmoleküle (PdP) sich zu dicht gepackten Ebenen anordnen. Diese PdP-SURMOF-Filme weisen ein hohes Maß an innerer Ordnung auf und sind dabei einfach aus Lösungen herstellbar. Diese Arbeit zeigt, dass der Transport von Triplett-Exzitonen innerhalb von PdP-SURMOF-Filmen tatsächlich effizient ist. Sprung-Raten zwischen benachbarten Molekülen auf der Größenordnung von $10^{11}\,\text{s}^{-1}$ können ermittelt werden. Zusammen mit der langen mono-molekularen Lebensdauer der Tripletts ermöglicht dies Diffusionslängen von mehreren Mikrometern. Der Exzitonen-Transport ist dabei stark anisotrop, da eindimensionale Diffusion zwischen benachbarten Porphyrin-Ebenen bevorzugt stattfindet. Weitere Experimente untersuchen den negativen Einfluss sowohl von anhaltender Beleuchtung als auch der Film-Morphologie auf die Transporteigenschaften des Materials. Insgesamt liefert diese Arbeit wichtige Erkenntnisse, die für den zukünftigen Einsatz von PdP-SURMOF-Filmen als Materialien für langreichweitigen Exzitonen-Transport von Bedeutung sind.

description: Originally, Parikh and Wilczek's work is only suitable for the massless particles' tunneling. But their work has been further extended to the cases of massive uncharged and charged particles' tunneling recently. In this paper, as a particular black hole solution, we apply this extended method to reconsider the tunneling effect of the H.S Dilaton black hole. We investigate the behavior of both massive uncharged and charged particles, and respectively calculate the emission rate at the event horizon. Our result shows that their emission rates are also consistent with the unitary theory. Moreover, comparing with the case of massless particles' tunneling, we find that this conclusion is independent of the kind of particles. And it is probably caused by the underlying relationship between this method and the laws of black hole thermodynamics.

Ταυτόχρονα, πραγματοποιήθηκε μια περαιτέρω μελέτη, χρησιμοποιώντας κατάλληλα μοντέλα με την εφαρμογή του πολυπαραγοντικού προγράμματος PLS. Ως εκ τούτου, ένας μεγάλος αριθμός φυσικοχημικών ιδιοτήτων καθώς και δομικών χαρακτηριστικών, υπολογίστηκαν και συμπεριλήφθηκαν στη μελέτη δίνοντας ποσοτική υπόσταση της συμβολής τους στο μηχανισμό κατακράτησης.
description: The particular utility of reverse phase columns in HPLC (RP-HPLC), combined with the need to generate representative rules concerning their retention mechanism, have led in modeling programs. In the present work, a comparative study is carried out between two stationary phases, C4 and phenyl, using a representative sample of probes (107 analytes) in two extreme pH values (2.3 and 6.2). This study focused on the impact of the % analytes ionization (based on pKa values) and their LogD values (at the corresponding pH values) on the retention mechanism. At the same time, in order to clarify the interactions between the analytes and the stationary and mobile phases, a further study was carried out using appropriate models by applying the multivariate program Partial Least Squares (PLS). Therefore, a large number of physicochemical properties and structural characteristics, were calculated and included in the study, in order to quantify their contribution to the retention mechanism.

description: The karyotypes of European bison Bison bonasus and domestic cattle Bos taurus are characterized by a diploid number of chromosomes, 2n = 60. Here, we characterized the European bison karyotype in terms of size and distribution of constitutive heterochromatin blocks (C-bands) and the location and number of nucleolar organizer regions (NORs), results were compared with those obtained for domestic cattle. For this purpose, staining for C and NOR bands was performed. In the chromosomes of both species, C-bands were located in the centromeric region of all chromosomes analyzed, except for the X chromosome. Active NORs in European bison chromosomes were identified in the chromosomes from pairs 2, 3, 4, 25, and 28. In cattle, NORs were located in chromosomes from pairs 2, 3, 4, 11, and 25. The average number of NORs in the cell of European bison and cattle was 4.47 ± 1.74 and 4.56 ± 1.66, respectively. The obtained results shed new light on the European bison cytogenetics and confirmed the high similarity between studied species.

description: Current Federal wetland protection efforts, such as the Swampbuster provision of the 1985 farm act, may be insufficient to attain the administration's goal of "no net loss" in wetland acreage. One option is to establish a permanent wetland reserve program, which this report discusses. The report reviews why wetlands are important, looks at past and present Federal wetland policies, and examines the dimensions of a reserve under three sizes. The likely geographic distribution of the reserve and likely crop rotations affected are both analyzed, and potential easement and restoration costs are estimated. Key questions about how a reserve will be implemented are highlighted.
title: Transnationalizing Lampedusa : representing migration in Italy and beyond
Creators: name: Colombini, Iacopo
Publisher: name: University of St Andrews
Year: 2019

description: This thesis explores the transnational dimension of Lampedusa, and how its symbolism can be used to address questions of identity and subjectivity in the cultural representation of migration. By examining the initiatives of the Archivio delle Memorie Migranti, the self-organised refugee group Lampedusa in Hamburg, and the Lampedusa-based Collettivo Askavusa, this work defines Lampedusa as a floating signifier. The discussion of the discursive formations composing what I defined, drawing on Benjamin, as the ‘Lampedusa transnational constellation’ highlights the centrality of cultural practices in affecting hegemonic representations of migration. This thesis recognises that the marginalisation of migrant and refugee voices in the public debate on migration is also partially reflected in the cultural projects that attempt to restore the agency of these individuals. The production and collections of new films, exhibitions, memories focusing on migrant deaths, passage and presence on Lampedusa, from the perspective of migrants themselves, are therefore considered playing a fundamental role, but are not seen as a straightforward solution. This works emphasises the importance of analysing the ‘moment of production’ of these cultural products, proposing forms of participant observation and multi-sited ethnographic work as a means to directly engage with the questions of race, identity, and positionality embedded in cultural practices focusing on migration.

description: Die Milchleistungen der Kühe sind in den zurückliegenden Jahren rasant gestiegen. Extrem hohe Leistungen haben jedoch nicht notwendigerweise in jedem Fall wirtschaftliche Vorteile; vor allem bei sehr hohen Kraftfutterkosten. Vorhandene physiologische Leistungsgrenzen sowie das begrenzte Futteraufnahmevermögen in Verbindung mit einer negativen Energiebilanz (NEB), vor allem in der Phase des Leistungspeaks, beeinflussen Tiergesundheit und Reproduktionsleistung der Milchkühe mit zunehmender Leistungshöhe.

Zukünftig wird die Bioethik bei der Erzeugung von Lebensmitteln tierischer Herkunft und für die Akzeptanz der Produkte in der Öffentlichkeit noch weitere  Bedeutung erlangen.

Auch unter diesem Aspekt sollte über die Zweckmäßigkeit extrem hoher Leistungen intensiver nachgedacht werden.

description: Durch die allgemeine Zunahme von Kurzurlaubsreisen sieht auch die Weinbranche in Europa immer mehr die wirtschaftlichen Vorteile und die damit einhergehenden positiven Synergien zwischen Wein und Tourismus. Das in unseren Breiten noch sehr junge Thema Weintourismus beschränkt sich in wissenschaftlichen Arbeiten meist auf die Angebotsstruktur und nicht auf die Erwartung der Konsumenten. In dieser Untersuchung wurden die Erwartungen von Weintouristen analysiert, um die aus der Literatur und die durch Experteninterviews gewonnenen Erkenntnisse für Weinbaugemeinden als Empfehlung zu Grunde legen zu können. Es zeigte sich, dass es nur eine geringe Zahl von Weinreisenden gibt, die explizit des Weines Willen in eine Region reist. Der Großteil der Touristen möchte im Kurzurlaub vom Thema Wein am Rande in Form eines Zusatzerlebnisses berührt werden. Es zeigt sich, dass die Erwartungen an diese Erlebnisse eher klassisch und traditionell geprägt sind. Primär stehen für den Touristen Entspannung und Genuss im Vordergrund, wobei sie offen sind, um „Neues Kennenzulernen“ und ihr Wissen über Wein durch kommunikative Vermittlung zu erweitern. Die Präferenz liegt auf Weinfeste und Weinveranstaltungen in Verbindung mit einem Erlebniswert. Erwartet werden Angebote an erklärten Weinverkostungen, Gemeinschaftsvinotheken und Gastronomie, die einen direkten Bezug zu Wein aufweisen.

description: In Deutschland ist die Biogasproduktion in den vergangenen zehn Jahren in erheblichem Umfang ausgebaut worden. Unter dem aktuellen EEG ist jedoch der weitere Biogasanlagenbau fast zum Erliegen gekommen, sodass der Eindruck entsteht, dass die Biogasproduktion an einem Wendepunkt angelangt ist und eine grundsätzliche Neuorientierung ansteht. Auf einzelbetrieblicher Ebene stehen bereits umfangreiche Analysen zu bisweilen aufgetretenen Effekten auf die Produktionsfaktoren Boden, Kapital und Arbeit zur Verfügung. Umfassende regionalökonomische Analysen, die alle Stufen der Biogas-Wertschöpfungskette berücksichtigen, sind dagegen nur sehr rar vorhanden. Vor diesem Hintergrund werden unter Zuhilfenahme der Ergebnisse einer empirischen Datenerhebung unter niedersächsischen Biogasanlagenbetreibern sowie Akteuren des vor- und nachgelagerten Bereichs die regionalwirtschaftlichen Effekte der Biogasproduktion dargestellt. Im Detail werden auf die regionale Verteilung der Zahlungsströme und -höhen in den verschiedenen Betriebsphasen einer Biogasanlage eingegangen sowie die Wertschöpfungs- und Arbeitsplatzeffekte im Zuge der Biogasproduktionslinie ermittelt. Die Ergebnisse zeigen unter anderem, dass ein Großteil der Wertschöpfung innerhalb Niedersachsens verbleibt. Mit ca. 70 % in der Bauphase und noch deutlich höheren Werten bei jährlichem Aufwand und Ertrag liegt dies im bundesweiten Vergleich über dem Durchschnitt.

Coordinate descent algorithms for lasso penalized regression

description: Imposition of a lasso penalty shrinks parameter estimates toward zero and performs continuous model selection. Lasso penalized regression is capable of handling linear regression problems where the number of predictors far exceeds the number of cases. This paper tests two exceptionally fast algorithms for estimating regression coefficients with a lasso penalty. The previously known $\ell_2$ algorithm is based on cyclic coordinate descent. Our new $\ell_1$ algorithm is based on greedy coordinate descent and Edgeworth's algorithm for ordinary $\ell_1$ regression. Each algorithm relies on a tuning constant that can be chosen by cross-validation. In some regression problems it is natural to group parameters and penalize parameters group by group rather than separately. If the group penalty is proportional to the Euclidean norm of the parameters of the group, then it is possible to majorize the norm and reduce parameter estimation to $\ell_2$ regression with a lasso penalty. Thus, the existing algorithm can be extended to novel settings. Each of the algorithms discussed is tested via either simulated or real data or both. The Appendix proves that a greedy form of the $\ell_2$ algorithm converges to the minimum value of the objective function.

description: Landwirtschaftspolitik und die Entwicklung des ländlichen Raums ist für die deutschen Bundesländer ein Politikfeld, welches sich mit der Etablierung der zweiten Säule der Gemeinsamen Agrarpolitik der EU deutlich erweitert hat. Landtage und insbesondere deren Agrarausschüsse rücken somit in den Fokus der Politikfeldforschung. In unserem Beitrag fragen wir, welche Faktoren die agrarpolitische Einstellung der Mitglieder der Agrarausschüsse der Bundesländer beeinflussen. Dafür unterscheiden wir grundlegend die Unterstützung eines agrarpolitischen Paradigmas des Produktivismus und des Paradigmas der Nachhaltigkeit. Die Auswertung unserer Abgeordnetenbefragung zeigt auf, dass die Fraktionszugehörigkeit und insbesondere die Nähe zu den verschiedenen agrarpolitischen Verbänden die Einstellungen der Parlamentarier erklären können. Individuelle soziostrukturelle Faktoren und Spezifika des Wahlkreises haben demgegenüber keine signifikanten Effekte.

description: Η υπόθεση εργασίας της συγκεκριμένης μεταπτυχιακής διπλωματικής εργασίας είναι οι συγκλίσεις και οι αποκλίσεις που παρουσιάζει η οργανωτική δομή των κομμάτων σε σχέση με την καταγεγραμμένη εκλογική τους δύναμη. Η δομή της εργασίας αποτελείται τόσο από τη παρουσίαση των βασικών θεωριών οργάνωσης των πολιτικών κομμάτων σε γενικό επίπεδο, όσο και από τον τρόπο με τον οποίο αποκρυσταλλώνονται η όχι στη πραγματικότητα σε ειδικό επίπεδο μέσα από μελέτη περίπτωσης (case study).Αναλυτικότερα, αντικείμενο της μελέτης περίπτωσης είναι το κόμμα του ΣΥΝ και του ΣΥΡΙΖΑ για τις εκλογές του 2009 και του 2012 στην εκλογική περιφέρεια της Α΄ Θεσσαλονίκης. Πιο συγκεκριμένα, συμπεριλαμβάνεται περιγραφή και ανάλυση της οργανωτικής διάρθρωσης του ΣΥΝ/ΣΥΡΙΖΑ, με βάση το μητρώο μελών του ΣΥΝ για το 2009 και του ΣΥΡΙΖΑ για το 2012, ο διαχωρισμός γίνεται γιατί το 2009 δεν υπήρχε μητρώο μελών του ΣΥΡΙΖΑ καθώς τότε ήταν συμμαχικό πολιτικό σχήμα, ενώ μόλις το 2012 απέκτησε χαρακτηριστικά ενιαίου κόμματος. Έπειτα, παρουσιάζεται η περιγραφή των αποτελεσμάτων του ΣΥΡΙΖΑ στην Α΄ Θεσσαλονίκης για τις τρείς εκλογές του 2009, 2012. Στη συνέχεια ακολουθεί η σύγκρισή των αποτελεσμάτων, βάση των οποίων αντλούνται τα συμπεράσματα σε σχέση με την υπόθεση εργασίας.
description: The working hypothesis of this dissertation is the convergences and divergences between the party structure with respect to the recorded electoral power. The structure of the work consists of both the presentation of the basic theories of organization of political parties in general, and by the way in which, they crystallized or not in a specific level through Case Study. In more detail, the subject of the case study is the party of SYN and SYRIZA for the elections of 2009 and 2012 in the constituency of A΄ Thessaloniki. More specifically, is included a description and an analysis of the organizational structure of SYN / SYRIZA, based on the register of members SYN for 2009 and SYRIZA for 2012. The distinction is made because in 2009 there was no register of members of SYRIZA, since it was an allied political figure, while only in 2012 acquired the characteristics of a unified party. Thereafter is presented the description of the results of SYRIZA in A΄ Thessaloniki for the three elections of 2009, 2012. Then there is a comparison of the results, based on which the conclusions are drawn with respect to the working hypothesis.

This picture shows the anastomosis of common carotid artery with internal jugular vein in AVF after surgery. The yellow arrow points to the sutures. The inflated jugular vein indicates the patency of the AVF. Scale bars = 1 mm. Fig. S2. Notch signaling conducts signals between neighboring cells. There are 5 Notch ligands including Jagged1/2, Dll1, 3 and 4; and 4 Notch receptors from 1 to 4. The interaction between Notch receptors and Notch ligands (Jagged/Delta) triggers 2 consecutive proteolytic cleavages by the ADAM10 metalloprotease and the γ-secretase complex. This generates Notch intracellular domain (NICD) which enters the nucleus and displaces corepressors and recruits the coactivator MAML1 and the acetyltransferase p300 to Notch transcription factor RBP-Jκ to initiate transcription of downstream signals. Canonical Notch signal can be blocked by KO of RBP-Jκ or overexpression of a dominant negative MAML1. Fig. S3. Contractile SMC markers are detected in mouse AVFs. Double immunofluorescent staining of α-SMA/transgelin (SM22) (A) and MYH11/calponin1 (CNN1) (B) were performed in 1 month AVFs. Scale bars = 50 μm. Fig. S4.

description: We study a mixture of fermionic and bosonic cold atoms on a two-dimensional optical lattice, where the fermions are prepared in two hyperfine (isospin) states and the bosons have Bose-Einstein condensed (BEC). The coupling between the fermionic atoms and the bosonic fluctuations of the BEC has similarities with the electron-phonon coupling in crystals. We study the phase diagram for this system at fixed fermion density of one per site (half-filling). We find that tuning of the lattice parameters and interaction strengths (for fermion-fermion, fermion-boson and boson-boson interactions) drives the system to undergo antiferromagnetic ordering, s-wave and d-wave pairing superconductivity or a charge density wave phase. We use functional renormalization group analysis where retardation effects are fully taken into account by keeping the frequency dependence of the interaction vertices and self-energies. We calculate response functions and also provide estimates of the energy gap associated with the dominant order, and how it depends on different parameters of the problem.

Development of liposomal bupivacaine using a transmembrane pH gradient
Creators: name: Mowat, Jeffrey John
Publisher: name: University of British Columbia

description: There is a clear clinical requirement for longer acting local anaesthetics, particularly for the management of post-operative and chronic pain. In this regard, liposomes have been suggested to represent a potentially useful vehicle for sustained drug release following local administration. In this thesis, a transmembrane pH gradient was employed to efficiently encapsulate bupivacaine within large unilamellar vesicles. The rate and extent of bupivacaine uptake into large unilamellar vesicles exhibiting a pH gradient (interior acidic) were determined and compared to drug association with control liposomes that did not exhibit a proton gradient. Subsequent studies examined the kinetics of bupivacaine release from the liposome systems in vitro. Using the Guinea Pig cutaneous wheal model, the rate of clearance of the liposome carrier was monitored following intradermal administration employing a radiolabeled lipid marker and the duration of nerve blockade produced by free and liposomal bupivacaine compared. Intraperitoneal injections of bupivacaine encapsulated in pH gradient vesicles, control (no pH gradient vesicles) and free drug were completed in mice to determine the relative toxicities. While bupivacaine is rapidly and efficiently accumulated within liposomes exhibiting a pH gradient (interior acidic), little uptake was seen for control vesicles. Using an in vitro model of drug clearance, liposomally encapsulated bupivacaine was found to be released more slowly and over a longer period of time compared to either the free drug or bupivacaine associated with control (no pH gradient liposomes). In the Guinea Pig cutaneous wheal model, over 85% of the liposomal carrier was found to remain at the site of administration over two days and the sustained drug release afforded by liposomes exhibiting a pH gradient resulted in a threefold increase in the duration of nerve blockade compared to either the free drug or bupivacaine in the presence of control (no pH gradient) liposomes. In the toxicity study, bupivacaine encapsulated in pH gradient vesicles showed a greater than fourfold increase in safety compared to the use of the free drug and control (no pH gradient) vesicles. The present results clearly establish that large unilamellar vesicles exhibiting a pH gradient can efficiently encapsulate bupivacaine and subsequently provide a sustained release system that greatly increases the duration of neural blockade and, in addition, reduces the toxicity.

description: In Phys. Rev. {\bf E 70}, 047102 (2004), J.R. Torgerson and S.K. Lamoreaux investigated for the first time the real-frequency spectrum of finite temperature correction to the Casimir force, for metallic plates of finite conductivity. The very interesting result of this study is that the correction from the TE mode is dominated by low frequencies, for which the dielectric description of the metal is invalid. However, their analysis of the problem, based on more appropriate low-frequency metallic boundary conditions, uses an incorrect form of boundary conditions for TE modes. We repeat their analysis, using the correct boundary conditions. Our computations confirm their most important result: contrary to the result of the dielectric model, the thermal TE mode correction leads to an increase in the TE mode force of attraction between the plates. The magnitude of the correction has a value about twenty times larger than that quoted by them.

description: Το αντικείμενο της παρούσας διπλωματικής εργασίας εντοπίζεται εντός του ευρύτερου πλαισίου του δικαίου της ενέργειας. Ειδικότερα, εξετάζεται υπό το πρίσμα του διοικητικού δικαίου, η ρύθμιση των αγορών δικτύου στον τομέα της ενέργειας, όπως αυτή αναδεικνύεται εξαιτίας της εφαρμογής της πολιτικής απελευθέρωσης στον εν λόγω τομέα. Βασική επιδίωξη της εργασίας αποτελεί η ανάδειξη της εκσυγχρονισμένης δημόσιας παρέμβασης όπως αυτή διαμορφώνεται μέσω της ρύθμισης των αγορών δικτύου ενέργειας. Στα πλαίσια αυτά, στο πρώτο μέρος της εργασίας, παρατίθεται και αναλύεται το συνολικό θεωρητικό υπόβαθρο που συνδέεται με τη ρύθμιση δικτυακών αγορών στον ενεργειακό τομέα, με αναφορές μεταξύ άλλων, στην έννοια της κοινής ωφέλειας που συνδέεται αναπόσπαστα με τον τομέα της ενέργειας, στο δικαίωμα πρόσβασης τρίτων στις ενεργειακές δικτυακές υποδομές αλλά και στους κανόνες περί διαχωρισμού των πρώην μονοπωλιακών κρατικών επιχειρήσεων που δραστηριοποιούνται στην αγορά ενέργειας. Προκειμένου να κατανοηθεί πληρέστερα η εφαρμογή και η λειτουργία στην πράξη του θεωρητικού πλαισίου σχετικά με τη ρύθμιση ενός ενεργειακού δικτύου, έπεται το δεύτερο μέρος της μελέτης στο οποίο επιχειρείται ειδικότερα μία προσπάθεια καταγραφής και ανάλυσης του ρυθμιστικού πλαισίου της εγχώριας αγοράς φυσικού αερίου όπως αυτό έχει διαμορφωθεί σήμερα, κυρίως επί τη βάσει των διατάξεων του Ν. 4001/2011.
description: The subject of the present thesis is focused on the wider field of energy law. In view of the liberalization policy in the energy sector the present elaboration evolves around the implemented regulatory framework of network industries active in the aforementioned sector, primarily under the light of administrative law. Main purpose of this thesis is to highlight the sophisticated involvement of the state, by way of state intervention, as formed through the energy network industries regulation. The first part of the thesis examines and further analyzes the existent regulatory framework of the energy network industries with references, among others, to the term of public utility, being an integral element of the energy sector, the third party access right to the energy networks infrastructures, as well as to the rules regarding the unbundling of the former monopolistic state enterprises operating in the energy market. In order to better understand how theory is implemented in practice in relation to the regulation of an energy network , the second part of this study attempts to depict and analyze the legal framework regulating the Greek natural gas market, especially in view of the provisions of the recent law no. 4001/2011.
