description: The possible violation of the weak cosmic censorship hypothesis in astrophysical phenomena can provide us with the information about trans-Planckian physics through observations. We present negative evidence, however, that one should not expect such a possibility at least when the deviation from spherical symmetry is negligible and the parameter values of collapse are astrophysically reasonable. Taking the Lemaître-Tolman-Bondi solution as the model most likely to counter the weak hypothesis, we show that the mass ($ \gtrsim 1.5 M_\odot $) and density ($ \gtrsim 1.5 \times 10^{15} \; {\rm g/cm^3}$) of the collapsing object produce a gravitational field strong enough to capture any null rays soon after emanating from the singularity.

Leptogenesis in the presence of exact flavor symmetries

Year: 2011
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In models with flavor symmetries in the leptonic sector leptogenesis can take place in a very different way compared to the standard leptogenesis scenario. We study the generation of a $B-L$ asymmetry in these kind of models in the flavor symmetric phase pointing out that successful leptogenesis requires (i) the right-handed neutrinos to lie in different representations of the flavor group; (ii) the flavons to be lighter at least that one of the right-handed neutrino representations. When these conditions are satisfied leptogenesis proceeds due to new contributions to the CP violating asymmetry and -depending on the specific model- in several stages. We demonstrate the validity of these arguments by studying in detail the generation of the $B-L$ asymmetry in a scenario of a concrete $A_4$ flavor model realization.

description: Effects of surface states on breakdown and gate-lag phenomena in narrowly-recessed-gate GaAs MESFETs are studied by two-dimensional (2-D) analysis. It is shown that the breakdown voltage could be raised when moderate densities of surface states are included. However, in a case with relatively high densities of surface states, the breakdown voltage could be drastically lowered when introducing a narrowly-recessed-gate structure. It is suggested that there is a trade-off relationship between raising the breakdown voltage and reducing the gate-lag.
Seagrass epifaunal communities of Barkley Sound : epifaunal diversity varies across small spatial and temporal scales
Creators: name: Whippo, Ross Douglas Byron
Publisher: name: University of British Columbia
Year: 2014

description: The assembly and persistence of ecological communities is a phenomenon that occurs across large spatial and temporal scales. However, the relative effects of regional versus local processes on community structure are not well understood in marine ecosystems. In order to understand how scale can alter processes that drive variation in community assembly it is necessary to determine patterns of diversity across multiple scales. Here, I used invertebrate epifaunal communities in the foundation species Zostera marina to test 1) whether this marine community exhibits meadow-scale variability through time, and 2) whether we can identify patterns of connectivity and diversity within and among meadows in the same region. I found that seagrass epifaunal communities are variable in terms of their rarefied richness, alpha and beta diversity, and evenness among meadows. In addition, differences in these metrics were detected over the course of a summer season.

description: An innovative approach to a quick design of multi-watts Ku-band power amplifiers for VSAT up-link applications is proposed. Starting from a set of specifically developed MMIC power macrocells, a modular imptementation is used to combine them into power modules requiring no adjustment and delivering up to 5W with 24dB associated gain in the 14-15.5GHz frequency band. The basic MMIC single chips exhibit a ldB gain compression output power of respectively : 200mW, 500mW and 1.6W.  3 W and 5W power modules are presented as examples
Estimating CDM Particle Trajectories in the Mildly Non-Linear Regime of Structure Formation. Implications for the Density Field in Real and Redshift Space

description: We obtain approximations for the CDM particle trajectories starting from Lagrangian Perturbation Theory. These estimates for the CDM trajectories result in approximations for the density in real and redshift space, as well as for the momentum density that are better than what standard Eulerian and Lagrangian perturbation theory give. For the real space density, we find that our proposed approximation gives a good cross-correlation (>95%) with the non-linear density down to scales almost twice smaller than the non-linear scale, and six times smaller than the corresponding scale obtained using linear theory. This allows for a speed-up of an order of magnitude or more in the scanning of the cosmological parameter space with N-body simulations for the scales relevant for the baryon acoustic oscillations. Possible future applications of our method include baryon acoustic peak reconstruction, building mock galaxy catalogs, momentum field reconstruction.

Subjects: ING-INF/01 Elettronica

description: For space applications an accurate estimate of the GaAs-FET lifetime is fundamental as it has a significant impact on the overall system design. The gate current is one of the most sensitive parameters regarding degradation modes, hence its behaviour under RF operation is a valid measure for lifetime. Different degradation and failure modes are analyzed and presented. The stress on the device under multicarrier operation when CW reliability data are available is simulated by means of a simplified amplifier model and the statistical properties of the applied RF signals.

description: Histone acetylation is a specific type of chromatin modifications that serves as a key regulatory mechanism for many cellular processes in mammals. However, little is known about its biological function in invertebrates. Here, we identified 12 members of histone deacetylases (NlHDACs) in the brown planthopper (BPH), Nilaparvata lugens. RNAi-mediated silencing assay showed that the NlHdac1, NlHdac3 and NlHdac4 played critical roles in female fertility via regulating ovary maturation or ovipositor development. Silencing of NlHdac1 substantially increased acetylation level of histones H3 and H4 in ovaries, indicating NlHDAC1 is the main histone deacetylase in ovaries of BPH. RNA sequencing (RNA-seq) analysis showed that knockdown of NlHdac1 impaired ovary development via multiple signalling pathways including the TOR pathway. Acoustic recording showed that males with NlHdac1 knockdown failed to make courtship songs, and thus were unacceptable to wild-type females, resulting in unfertilized eggs. Competition mating assay showed that wild-type females overwhelmingly preferred to mate with control males over NlHdac1-knockdown. These findings improve our understanding of reproductive strategies controlled by HDACs in insects and provide a potential target for pest control.

description: A 24 GHz high-performance Doppler sensor for non-contact measurement of vehicle speed and position is reported. The compact dimensions and the economical design make the sensor ideally suited for automotive applications. A special feature is the 24 GHz fundamental-frequency dielectric resonator oscillator employing a low-cost packaged HEMT. An excellent phase-noise behavior and good temperature stability are achieved due to higher-order mode operation of the dielectric resonator. The new Doppler sensor provides high reliability and gives excellent measurement results in both car and train tests.
Updated Mass Scaling Relations for Nuclear Star Clusters and a Comparison to Supermassive Black Holes

description: We investigate whether nuclear star clusters and supermassive black holes follow a common set of mass scaling relations with their host galaxy's properties, and hence can be considered to form a single class of central massive object. We have compiled a large sample of galaxies with measured nuclear star cluster masses and host galaxy properties from the literature and fit log-linear scaling relations. We find that nuclear star cluster mass, M_{NC}, correlates most tightly with the host galaxy's velocity dispersion: log M_{NC} = (2.11 \pm 0.31) log (σ/54) + (6.63 \pm 0.09), but has a slope dramatically shallower than the relation defined by supermassive black holes. We find that the nuclear star cluster mass relations involving host galaxy (and spheroid) luminosity and stellar and dynamical mass, intercept with but are in general shallower than the corresponding black hole scaling relations. In particular M_{NC} \propto {M}_{Gal,dyn}^{0.55 \pm 0.15}; the nuclear cluster mass is not a constant fraction of its host galaxy or spheroid mass. We conclude that nuclear stellar clusters and supermassive black holes do not form a single family of central massive objects.

description: The design, fabrication and performance results of a fully monolithic linear vector modulator are described. The circuit is designed for a 5.0 - 5.6 GHz frequency range. The insertion loss of the device is typically 4 dB with input and output return losses better than 7 dB and 15 dB respectively. The RMS amplitude error is typical 0.4 dB and the RMS phase error typical 2.3 degrees over 255 states. These figures can be improved by correcting the systematic amplitude and phase errors of the device by a look-up table. The RMS amplitude error is reduced to 0.2 dB while the RMS phase error is less than 1.2 degrees.

Subjects: ING-INF/01 Elettronica

description: This paper reports on the development of two generic satellite transponder channel amplifier subsystems for the 5.35-5.65 GHz band, respectively the 10.70-12,75 GHz band, both to be based on full application of GaAs MMIC technology. A novel Slope Compensation MMIC is introduced as a curative counter-measure to minimize residual inband gain ripple and slope. Furthermore, a control loop algorithm is used to account for all principal control characteristics, all interdependencies between them and all temperature effects. Measurements show competitive inband ripple-slope values for all gain settings over the complete temperature range.

description: In this paper we present a (2x5) matrix amplifier with a DC power consumption as low as 200 mW with 13 dBm of RF output power (@ 1 dB compression point) achieving 7 dB of small-signal gain (residual ripple 0.3 dB) and input-output return loss always better than -14 dB. Designed using the LN05 monolithic process of Thomson Composants Microondes (TCM), the amplifier employs ten MESFETs of 160 µm (4x40 nm) gate width and sub-micron (0.5 µm) gate length, for a total chip area of 2.5x3.5 mm2. Broadband performance and very low power consumption make this amplifier very well suited for high-volume realization of monolithic multiple-stage front-ends in integrated high bit-rate fiber-optic receivers.

description: Recent years have witnessed the proliferation of victim-focused positions inside and outside the criminal justice system, yet little is known about the occupational characteristics and organizational context of this field in the United States. In this article, we draw on 42 semi-structured interviews with victim workers from a variety of settings and organizational affiliations in the midwestern USA to describe their pathways, activities, and challenges. The data reveal key differences among the experiences of those who were publicly employed, affiliated with the nonprofit sector and working independently. The findings underscore the significance of organizational affiliation in understanding victim work, the value of strong public/private partnerships, and the necessity of reforms to the organizational culture of criminal justice agencies to optimize victim experiences.

description: The mobile communication market is the current driving force of the European telecommunication industry with remarkable growth rates. In March 1990 about 2.5 million mobile communication systems have found application in Europe with a forecast of more than 90 million DECT-GSM-PCN systems up to the year 2000. This situation is of great benefit for the semiconductor industry in general and the GaAs components suppliers especially. The reason is that GaAs components maintain their sophisticated performance - low NF and high PAE -under the stringent low power consumption conditions of a handheld. Moreover, the established low-loss GaAs MMIC technology allows in the meantime the production of small SMDs at a reasonable price. In the following, we describe a complete set of GaAs and Silicon devices suitable for the new digital communication systems.

description: In der letzten Zeit erfuhr der europäische Agrarsektor deutliche Veränderungen aufgrund der Reform der GAP mit der Entkoppelung der Direktzahlungen, Modulation und Cross-Compliance. Der Ausgangspunkt von dem die hier vorliegende Studie ausgeht, sind die Auswirkungen der politisch induzierten Veränderungen der Rahmenbedingungen bzw. die Erweiterung der zu berücksichtigenden Interessen in der agrarischen Landnutzung, die weit über das rein betriebswirtschaftliche hinausgehen, auf die Struktur landwirtschaftlicher Betriebe in der EU. Der Fokus dieser Studie liegt auf den räumlichen und zeitlichen Auswirkungen unterschiedlicher Maßnahmen der GAP-Reform. Aus diesem Grund ist die Integration eines geographischen Informationssystems in AgriPoliS ein wesentlicher Beitrag zur Weiterentwicklung des Modells innerhalb der vorliegenden Arbeit. Weiterhin wurde AgriPoliS auf die Sensitivität hinsichtlich der Initialisierung der Standorte von Betrieben und der räumlichen Verteilung der unterschiedlichen Bodenqualitäten getestet. Nachdem eine Möglichkeit zur Beurteilung der Verlässlichkeit von AgriPoliS präsentiert wurde, wird diese als Grundlage für die Untersuchung der Auswirkungen unterschiedlicher Szenarien zur Umsetzung der GAP-Reform von 2003 auf den Strukturwandel in drei europäischen Regionen angewendet. Untersucht werden die Regionen Ostprignitz-Ruppin in Deutschland, Mugello in Italien und Gudenå in Dänemark. Die Untersuchung dieser drei Regionen zeigt gleichzeitig zu welchen unterschiedlichen Entwicklungen die gleichen Politikszenarien in verschiedenen europäischen Regionen führen.

description: Il problema dell’erosione costiera, è purtroppo una realtà sempre più presente della
quale prendere atto. I dati mostrano che ad oggi, il 42 % delle coste Italiane sono in
erosione. Per far fronte a questa lenta e inesorabile “battaglia” con il mare, si è cercato
di proteggere i litorali con adeguate opere di difesa. In modo particolare, negli ultimi
anni, sono state introdotte tecniche “soft”quali i ripascimenti.
Tale tecnica consiste nell’apporto di materiale di idonee caratteristiche sulle spiagge
soggette all’erosione.
Ciò che si vuole evidenziare in questo ambito, è il problema della fonte di sabbia per
eseguire questo tipo di intervento. Sarà presa visione di un progetto attuato in Emilia-
Romagna,il Progettone, di ripascimento con sabbie sottomarine, da confrontare con una
nuova ipotesi: prelevare la sabbia presente a monte dello sbarramento di Isola Serafini,
situata lungo l’asta fluviale del Po.
Tale sabbia, andrebbe comunque dragata per garantire la navigabilità del corso d’acqua
L’intervento di ripascimento viene ipotizzato sulla spiaggia di Misano Adriatico.
Si valuteranno pertanto le caratteristiche granulometriche della sabbia del Po,
confrontandole con quella di Misano Adriatico, e valutandone la compatibilità.
Tramite un semplice modello matematico, si cercherà di quantificare il trasporto di
materiale longshore per comprendere al meglio l’entità del ripascimento da attuare.
Si farà inoltre un breve accenno sulla questione del trattamento del materiale per
abbattere le eventuali sostanze contaminanti.
Infine, si valuterà la fattibilità in termini economici dell’intervento, in relazione al tipo
di trasporto che si intende utilizzare.

description: We work with a newly developed method to empirically assess whether a specified new-Keynesian business cycle monetary model estimated with U.S. quarterly data is consistent with a unique equilibrium or multiple equilibria under rational expectations. We conduct classical tests to verify if the structural model is correctly specified. Conditional on a positive answer, we formally assess if such model is either consistent with a unique equilibrium or with indeterminacy. Importantly, our full-system approach requires neither the use of prior distributions nor that of nonstandard inference. The case of an indeterminate equilibrium in the pre-1984 sample and of a determinate equilibrium in the post-1984 sample is favored by the data. The long-run coefficients on inflation and the output gap in the monetary policy rule are found to be weakly identified. However, our results are further supported by a proposed identification-robust indicator of indeterminacy.

description: We present a systemic analysis of all of the stellar mass black hole binaries (confirmed & candidate) observed by the Swift observatory up to June 2010. The broad Swift bandpass enables a trace of disk evolution over an unprecedented range in flux and temperature. The final data sample consists of 476 X-ray spectra containing greater than 100 counts, in the 0.6 -- 10 keV band. This is the largest sample of high quality CCD spectra of accreting black holes published to date. In addition, strictly simultaneous data at optical/UV wavelengths are available for 255 (54%) of these observations. The data are modelled with a combination of an accretion disk and a hard spectral component. For the hard component we consider both a simple power-law and a thermal Comptonization model. An accretion disk is detected at greater than the 5sigma confidence level in 61% of the observations. Lightcurves and color-color diagrams are constructed for each system. Hardness luminosity and disk fraction luminosity diagrams are constructed and are observed to be consistent with those typically observed by RXTE, noting the sensitivity below 2 keV provided by Swift. The observed spectra have an average luminosity of ~ 1% Eddington, though we are sensitive to accretion disks down to a luminosity of 10^{-3} L_Edd. Thus this is also the largest sample of such cool accretion disks studied to date. (abridged)

description: L’oggetto di questo lavoro è il cinema italiano dei primi anni Cinquanta e nello specifico il modo in cui esso si è articolato in generi. Non è un catalogo dei generi italiani, ma un tentativo di mettere i modelli teorici più consolidati alla prova di quella produzione. 
Il primo capitolo ripercorre la tradizione storiografica sugli anni Cinquanta, mettendola in relazione con le letture del neorealismo ed esaminando i motivi per cui la nozione di genere è stata costitutiva dell’interpretazione stessa del decennio. 
Nel secondo capitolo si chiarisce la proposta metodologica, introducendo le nozioni di intertestualità (intesa come approccio analitico attento alla circolazione di figure, anziché alle singolarità testuali), visibile (relazione costruttiva tra immagine cinematografica e immagine del «reale») e bozzetto (inteso come forma simbolica tipica di quel cinema). 
L’applicabilità al caso italiano dei più accreditati modelli di teoria dei generi cinematografici, in particolare quelli proposti da Rick Altman, Francesco Casetti e Steve Neale, è l’oggetto del terzo capitolo, nel quale si rilevano, oltre alle evidenti differenze, anche le affinità che esistono tra il sistema “debole” dei generi italiani e il paradigma hollywoodiano. 
Nel quarto capitolo si descrivono alcuni topoi specifici di quel cinema e si ipotizza che la loro dilatazione, la loro replicabilità di film in film stiano alla base della costruzione dei testi di genere.

Bezüglich der Effekte des durchgeführten Entspannungstrainings konnte ein signifikanter Haupteffekt Gruppe für MIPS-PS-Wettkampf und ein signifikanter Haupteffekt Zeit für MIPS-NR-Training und MIPS-PS-Wettkampf, jedoch kein signifikanter Interaktionseffekt Gruppe * Zeit gefunden werden.
The St. George Rainway : building community resilience with green infrastructure
Creators: name: Welsh, Joshua
Publisher: name: University of British Columbia

description: This thesis was written with cognizance of humanity’s passage into the current epoch: the Anthropocene. Impacts the human species currently have upon the biosphere are physically and chemically altering it to degrees that have crossed thresholds of sustainability. The side effects of this call for resilience to enable healthful transitions into the unstable and unpredictable future. Central to global climate change and central to the profession of landscape architecture is the element: water. The St. George Rainway offers a new opportunity to be a demonstration project for the City of Vancouver where the City and the community of Mount Pleasant act as collaborators with design, construction, and maintenance of a project with water in the public realm. There are three components essential to this work: a community survey, a series of stakeholder and expert interviews, and a design-application of theory using landscape architecture. The survey and interviews establish the local context for the thesis, a baseline for presence of social cohesion, and a framing for the applicability of the ten prominent characteristics of resilient communities. Taken together, the application of design responds to the collective voice and needs of the community and provides a set of goals, phases, strategies for design as a framework to help realize future implementation of the St. George Rainway. The voluntary engagement in the physical transformation of one’s community can provide opportunity for a growth in social cohesion. Subsequently, this growth can improve the conditions that fostered the bonds and bridges within that community that inspired the initial voluntary engagement. Green infrastructure, when considered through this lens, has a reciprocal relationship with social cohesion, where the improvement of one feeds into the improvement of the other. This model could therefore provide both a resilient option for physical development of land and for social development of community for a neighbourhood like Mount Pleasant by encouraging more interaction among neighbours and with the local public realm. The St. George Rainway: Building Community Resilience with Green Infrastructure aims to provide a framework for this.

description: We study the evolution of scalar cosmological perturbations in the (1+3)- covariant gauge-invariant formalism for generic $f(R)$ theories of gravity. Extending previous works, we give a complete set of equations describing the evolution of matter and curvature fluctuations for a multi-fluid cosmological medium. We then specialize to a radiation-dust fluid described by barotropic equations of state and solve the perturbation equations around a background solution of $R^{n}$ gravity. In particular we study exact solutions for scales much smaller and much larger than the Hubble radius and show that $n>2/3$ in order to have a growth rate compatible with the Mészáros effect.

description: This paper discusses a consistent bootstrap implementation of the likelihood ratio [LR] co-integration rank test and associated sequential rank determination procedure of Johansen (1996). The bootstrap samples are constructed using the restricted parameter estimates of the underlying VAR model which obtain under the reduced rank null hypothesis. A full asymptotic theory is provided which shows that, unlike the bootstrap procedure in Swensen (2006) where a combination of unrestricted and restricted estimates from the VAR model is used, the resulting bootstrap data are I(1) and satisfy the null co-integration rank, regardless of the true rank. This ensures that the bootstrap LR test is asymptotically correctly sized and that the probability that the bootstrap sequential procedure selects a rank smaller than the true rank converges to zero. Monte Carlo evidence suggests that our bootstrap procedures work very well in practice.
Towards an Optimal Reconstruction of Baryon Oscillations

description: The Baryon Acoustic Oscillations (BAO) in the large-scale structure of the universe leave a distinct peak in the two-point correlation function of the matter distribution. That acoustic peak is smeared and shifted by bulk flows and non-linear evolution. However, it has been shown that it is still possible to sharpen the peak and remove its shift by undoing the effects of the bulk flows. We propose an improvement to the standard acoustic peak reconstruction. Contrary to the standard approach, the new scheme has no free parameters, treats the large-scale modes consistently, and uses optimal filters to extract the BAO information. At redshift of zero, the reconstructed linear matter power spectrum leads to a markedly improved sharpening of the reconstructed acoustic peak compared to standard reconstruction.

description: We prove that the smallest degree of an apolar $0$-dimensional scheme to a general cubic form in $n+1$ variables is at most $2n+2$, when $n\geq 8$,  and therefore smaller than the rank of the form.  When $n=8$ we show that the bound is sharp, i.e. the smallest degree of an apolar subscheme is $18$.

description: Der Ladevorgang eines Kranrückezuges bietet aufgrund des hohen Zeitanteils am gesamten Arbeitsprozess ein nennenswertes Potential für Energieeinsparung. Dabei soll der mechanische Aufbau des Ladekranes nicht modifiziert werden, um weiter mit Kranen arbeiten zu können, die in größeren Stückzahlen hergestellt werden. Mit Hilfe von zwei Hydro-Transformatoren mit konstanter Übersetzung wird ein Hybridantrieb aufgebaut, der sowohl die Lageenergie des gesamten Armsystems rekuperiert, als auch bei der parallelen Bewegung von Hub- und Wipparm die Lageenergie des abgesenkten Arms in den gehobenen Arm regeneriert. Die Potentiale der Energieeinsparung während der vertikalen und der horizontalen Bewegung der Kranspitze werden in diesem Bericht untersucht und abgeschätzt.

Micro-plasticity and intermittent dislocation activity in a simplified micro structural model

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Here we present a model to study the micro-plastic regime of a stress-strain curve. In this model an explicit dislocation population represents the mobile dislocation content and an internal shear-stress field represents a mean-field description of the immobile dislocation content. The mobile dislocations are constrained to a simple dipolar mat geometry and modelled via a dislocation dynamics algorithm, whilst the shear-stress field is chosen to be a sinusoidal function of distance along the mat direction. The latter, defined by a periodic length and a shear-stress amplitude, represents a pre-existing micro-structure. These model parameters, along with the mobile dislocation density, are found to admit a diversity of micro-plastic behaviour involving intermittent plasticity in the form of a scale-free avalanche phenomenon, with an exponent for the strain burst magnitude distribution similar to those seen in experiment and more complex dislocation dynamics simulations.

description: Antidesmon, ein neuartiges pflanzliches Alkaloid, wurde auf seine Wirkung gegen humanpathogene Protozoen in vitro getestet. Es fand sich eine bisher unbekannte Wirkung auf Trypanosoma cruzi, den Erreger der Chagas-Krankheit, für Antidesmon (IC50-Wert 0,04 µg/ml), die die Wirkung des Standardmedikamentes Benznidazol (IC50-Wert 0,6 µg/ml) übertraf. Das Derivat AdOMeb wirkte in einer 90fach niedrigeren Konzentration als Benznidazol auf T. cruzi und übertraf mit einem IC50-Wert von 0,007 µg/ml die Wirksamkeit der Muttersubstanz Antidesmon. Zwei weitere Derivate, AdOL und AdAc, wirkten ebenfalls in niedrigerer Konzentration als Benznidazol. Mit Antidesmon wurde im Rahmen dieser Arbeit eine neue Leitstruktur zur Entwicklung dringend benötigter Medikamente gegen T. cruzi gefunden. Durch N-Methylierung am ersten Ring des Bicyclus konnte die Wirksamkeit der Muttersubstanz um das Fünffache gesteigert werden; gleichzeitig verringerte sich die Toxizität auf Säugetierzellen. Für die Wirkung von Antidesmon und seinen Derivaten wurde in Deutschland und international ein Patent erteilt.
description: Antidesmone, a novel plant alkaloid, was tested for antiprotozoal activity against pathogenic protozoa in vitro. Activity against Trypanosoma cruzi, the causative agent of Chagas' disease, was found. The IC50 value of Antidesmone (IC50 0,04 µg/ml)was lower than that of the standard drug benznidazole (IC50 value 0,6 µg/ml). The derivative AdOMeb had an even lower IC50 value of 0,007 µg/ml. Antidesmone is a novel lead structure for the development of antitrypanosomal compounds. By N-methylation at the first ring of the bicyclus the acitivity was fivefold increased and the toxicity for mammalian cells reduced.

description: Die therapeutische Effektivität jeder topisch auf die Haut applizierten Arzneimittelpräparation ist abhängig von den Wirkstoffeigenschaften, dem jeweiligen Hautzustand und dem verwendeten Vehikel. Mit dem Ziel, durch Modulation des eingesetzten Vehikels die Bedingungen für ein optimales Konzentrations-Zeit-Profil von α-Tocopherolacetat zu ermitteln, wurden ex vivo-Penetrationsuntersuchungen mit Standardemulsionen, kolloidalen Trägersystemen und Penetrationsmodulatoren durchgeführt. Nach 30 und 300 minütiger Inkubationszeit wurden die Konzentrationen des penetrierten Wirkstoffs in die Schichten der menschlichen Haut ermittelt und graphisch dargestellt. Dabei zeigten sich erhebliche Unterschiede im Penetrationsverhalten von α-Tocopherolacetat in Abhängigkeit vom verwendeten Vehikel. Durch Auswahl eines Vehikels wurden die Ergebnisse der ex vivio-Untersuchungen an 12 gesunden Probanden überprüft. Das auf die Innenseite der Unterarme aufgetragene α-Tocopherolacetat-haltige Trägersystem wurde nach 30 und 300 Minuten durch Abwischen des Überstandes entfernt. Der penetrierte Anteil wurde mittels Eluation durch ein lipophiles Lösungsmittel entfernt. und mittels HPLC untersucht. Die Ergebnisse ließen Rückschlüsse auf die Kinetik der α-Tocopherolacetat-Penetration in die menschliche Haut unter in vivo Bedingungen zu, die beim eingesetzten Vehikel bereits nach 30 Minuten Inkubationszeit ihren höchsten Wert erreicht hatte.
description: The therapeutic efficiency of each topical, on skin applied drugpenetration is depent on characteristics of activ substance, each skin condition and used vehicel. The mean idea was by modulation of the used vehicel to reach a optimal concentration-time-profile of α-tocopherolaetate by investigations of ex vivo penetration with standardemulsions, kolloidal carriersystems and modulators of penetration. After 30 and 300 minutes incubationtime the concentration of penetrated substance in the layer of human skin was measured and grafic shown. In the results was shown considerable differences of penetrationbehavior of α-tocopherolacetate depend on used vehicle. The results of ex vivo investigation was tested by 12 healthy volunteers by using of one vehicle. The carriersystem with α-tocopherolacetate aws topical applied on forearm inside and wipe away of non penetrated substance at the end of penetrationtime, after 30 and 300 minutes. The penetrated part was eluated by a lipophilic solution and measured by HPLC. The results represent the kinetic of in vivo α-tocopherolacetate penetration in human skin. After 30 mnutes incubationtime was finished the penetration by used vehicle.
