description: Der bevorstehende Atom- und Kohleausstieg stellt Deutschland vor große Herausforderungen bezüglich der sicheren und kostengünstigen Energieversorgung dar. Hierbei sollten vorallem erneuerbare Energien große Abhilfe schaffen. Aufgrund der fluktuativen Charakteristik werden Energiespeicher in das Netz integriert, welche Leistungsspitzen der Energieerzeuger effizient abfangen und bei einem Engpass dem netz wieder zur Verfügung stellen können. In diesem Zusammenhang bietet die in Deutschland stets voranschreitende Elektromobilität, bezüglich eines bidirektionalen Energieaustauschs, eine bislang ungenutzte Kapazität. Durch die Weiterentwicklung aktueller Ladetechnologien und spezieller Ladestrategien, sowie der Einführung von Standards in diesem Bereich, können am Netz angeschlossene Fahrzeuge als solche Energiespeicher betrachtet und verwendet werden. Mit Einbeziehung der Fahrzeuge in das Energiesystem, können erhebliche Einsparungen in Bezug auf Geld, Zeit und Ressourcen erzielt werden. Die vorliegende Bachelorarbeit befasst sich mit der Bedeutsamkeit der Eingliederung von Elektrofahrzeugen in das Energienetz. In diesem Zusammenhang wurde eine Ladestation entwickelt, welche Smart Grid Konzepte, wie das Grid to Vehicle, unterstützt und essentielle Daten über ein angeschlossenes Backend zur Verfügung stellen kann. Mithilfe dieses Aufbaus konnte die Funktionsweise getestet und daran geknüpfte Bedingungen festgestellt werden.

description: A class of $(2n)^2\times(2n)^2$ multiparameter braid matrices are presented for all $n$ $(n\geq 1)$. Apart from the spectral parameter $θ$, they depend on $2n^2$ free parameters $m_{ij}^{(\pm)}$, $i,j=1,...,n$. For real parameters the matrices $R(θ)$ are nonunitary. For purely imaginary parameters they became unitary. Thus a unification is achieved with odd dimensional multiparameter solutions presented before.

description: Software faults are commonly occurred due to interactions between one or more input parameters in complex software systems. Software test design techniques can be implemented to ensure the quality of the developed software. Exhaustive testing tests all possible test configurations; however, it is infeasible considering time and resource constraints. Pairwise t-way testing is a sampling strategy that focuses on testing every pair of parameter combination, effectively reducing the generated test size as opposed to testing exhaustively. In this paper, we propose a new pairwise t-way strategy called Pairwise Gravitational Search Algorithm Strategy (PGSAS). PGSAS utilizes Gravitational Search Algorithm (GSA) for generating optimal pairwise test suites. The performance of PGSAS is benchmarked against existing t-way strategies in terms of test suite size. Preliminary results showcase that PGSAS provides competitive results in most configurations and outshines other strategies in some cases.

The Structure of Classical Bulges And Pseudobulges: The Link Between Pseudobulges And Sersic Index

description: In this paper we study the properties of pseudobulges (bulges that appear similar to disk galaxies) and classical bulges (bulges which appear similar to E-type galaxies) in bulge-disk decompositions. We show that the distribution of bulge Sersic indices is bimodal, and this bimodality correlates with the morphology of the bulge. Pseudobulges have n<2 and classical bulges have n>2 with little overlap. Also, pseudobulges do not follow the correlations of Sersic index with structural parameters or the photometric projections of the fundamental plane in the same way as classical bulges and elliptical galaxies do. We find that pseudobulges are systematically flatter than classical bulges and thus more disk-like in both their morphology and shape. We do not find significant differences between different bulge morphologies that we are collectively calling pseudobulges (nuclear spirals, nuclear rings, nuclear bars, and nuclear patchiness) appear to behave similarly in all parameter correlations. In Sersic index, flattening, and bulge-to-total ratio, the distinction appears to be between classical bulges and pseudobulges, not between different pseudobulge morphologies. The Sersic index of the pseudobulges does not correlate with B/T, in contrast to classical bulges. Also, the half-light radius of the pseudobulge correlates with the scale length of the disk; this is not the case for classical bulges. The correlation of Sersic index and scale lengths with bulge morphology suggests that secular evolution is creating pseudobulges with low-Sersic index, and that other processes (e.g. major mergers) are responsible for the higher Sersic index in classical bulges and elliptical galaxies.

description: Exact two-dimensional analytic wave functions for an arbitrary number $N$ of contact-interacting lowest-Landau-level (LLL) spinful fermions are derived with the use of combined numerical and symbolic computational approaches via analysis of exact Hamiltonian numerical diagonalization data. Closed-form analytic expressions are presented for two families of zero-interaction-energy states at given total angular momentum and total spin $0 \leq S \leq N/2$ in the neighborhood of the $ν=1$ filling, covering the range from the maximum density droplet to the first quasihole. Our theoretical predictions for higher-order spatial and momentum correlations reveal intrinsic polygonal, multi-ring crystalline-type structures, which can be tested with ultracold-atom experiments in rapidly rotating traps, simulating quantum Hall physics (including quantum LLL skyrmions).

An examination of wildlife policy in Spatsizi Plateau Wilderness Park
Creators: name: Pearse, Anthony Dalton
Publisher: name: University of British Columbia
Year: 2010

description: My objective in this thesis is to compare the correlation between policy intent and policy outcome with respect to wildlife management in Spatsizi Plateau Wilderness Park. The Order-in-Council establishing the park articulates a management policy which is to allow "natural communities to remain intact and the progressions of natural systems to proceed without alteration." The study begins by interpreting the policy statement to mean that no human action will be permitted within the park that will disrupt the ecological order of existing wildlife communities. The subsequent analysis is divided into four stages. First, I identify the key, operating principles that govern northern boreal forest ecosystems such as that characterizing Spatsizi. Second, I formulate management guidelines from these identified ecological principles. This is followed by a review of prevailing management practices in the park. Last I assess the prevailing practices in terms of their consistency with my derived guidelines in order to determine to what extent policy objectives are being met. The results of this analysis revealed that of six management guidelines developed for Spatsizi wildlife policy, only one was presently being implemented by park managers. The conclusion is that current wildlife management in Spatsizi Park is not being carried out on an ecologically sound basis and, therefore, is not achieving, and is unlikely to achieve, the objectives of the stated policy. Empirical support is lent to this conclusion by the apparent decline of several ungulate populations within the park. My recommendations include a temporary suspension of all bunting within and adjacent to the park until the necessary biological studies have been conducted and the essential criteria for enabling the harvest to occur in accordance with the policy mandate have been met. An essential element here is that a wildlife refuge containing viable populations of all big game species in the Spatsizi region be established wherein no development or exploitation of wildlife be allowed to take place.

description: We study the FCNC $B_s \to ϕγ, ϕν\bar ν$ and $Λ_b \to Λγ, Λν\bar ν$ transitions in the Standard Model and in a scenario with a single Universal Extra Dimension. In particular, we focus on the present knowledge of the hadronic uncertainties and on possible improvements. We discuss how the measurements of these modes can be used to constrain the new parameter involved in the extra dimensional scenario, the radius $R$ of the extra dimension, completing the information available from B-factories. The rates of these $b \to s$ induced decays are within the reach of new experiments, such as LHCb.

description: In the event of a kidnapping or a medical emergency, a person is often incapacitated to be able to call for help. And it's usually too late before the first responders arrive on-scene. Currently, a vast array of 'safety' devices available in the market are often far too rudimentary such as double tapping the power button that isn't very practical, or an app on a smart watch that is a huge investment in the first place. The Smart Band aims to eliminate the need for a physical trigger by the person who finds himself in dangerous situations like kidnapping, front-facing some wild animal, heart attack, etc., and rather senses the heartbeat. The Smart Band is designed as a personalized wearable device, wherein the user heart beat rate is collected and trained using machine learning algorithm, which triggers the alert system automatically when the event is identified. Hence the accuracy of assessing emergency situation will be high and false rate will be reduced. As soon as the event is detected, the band relays GPS coordinates to first responders and emergency contacts, which will be sent via the Network Carrier (SIM card module) directly from the band, not relying on a mobile phone, which is usually out of reach during such emergency situations. In essence, the Smart Band consists of a GPS tracker, a heartbeat sensor, a Network module, and a Bluetooth module, all existing technologies which have been mass produced to an extent that the end product can be made affordable, and in huge quantities as well. On further development the smart band can be customized to a finely wearable jewel which can serve the purpose autonomously.

description: On megaparsec scales the Universe is permeated by an intricate filigree of clusters, filaments, sheets and voids, the Cosmic Web. For the understanding of its dynamical and hierarchical history it is crucial to identify objectively its complex morphological components. One of the most characteristic aspects is that of the dominant underdense Voids, the product of a hierarchical process driven by the collapse of minor voids in addition to the merging of large ones. In this study we present an objective void finder technique which involves a minimum of assumptions about the scale, structure and shape of voids. Our void finding method, the Watershed Void Finder (WVF), is based upon the Watershed Transform, a well-known technique for the segmentation of images. Importantly, the technique has the potential to trace the existing manifestations of a void hierarchy. The basic watershed transform is augmented by a variety of correction procedures to remove spurious structure resulting from sampling noise. This study contains a detailed description of the WVF. We demonstrate how it is able to trace and identify, relatively parameter free, voids and their surrounding (filamentary and planar) boundaries. We test the technique on a set of Kinematic Voronoi models, heuristic spatial models for a cellular distribution of matter. Comparison of the WVF segmentations of low noise and high noise Voronoi models with the quantitatively known spatial characteristics of the intrinsic Voronoi tessellation shows that the size and shape of the voids are succesfully retrieved. WVF manages to even reproduce the full void size distribution function.

description: Personal in medizinischen Einrichtungen kann ein wichtiger Multiplikator im Infektionsgeschehen bei impfpräventablen Erkrankungen sein. Gleichzeitig kann diese Gruppe dieselben Vorbehalte, Informationsdefizite und praktischen Hemmnisse gegenüber Impfungen haben wie die Gesamtbevölkerung (Betsch, von Hirschhausen & Zylka-Menhorn, 2019, S.521). Ziel dieser Arbeit ist es, die Impfbereitschaft von Personal in medizinischen Einrichtungen für eine Impfung gegen COVID-19 und Influenza zu betrachten. Die psychologischen Beweggründe einer Impfentscheidung werden identifiziert, um daraus Handlungsempfehlungen für das Setting Krankenhaus zu entwickeln. Es werden zur COVID-19-Impfung und zur Influenza-Impfung systematische Literaturrecherchen in zwei Datenbanken vorgenommen. 37 Quellen werden ausgewertet und die Ergebnisse zusammengefasst. Anschließend werden 23 selektierte Quellen einer Analyse nach fünf psychologischen Antezedenzien der Impfbereitschaft — Vertrauen, Risikowahrnehmung, Barrieren in der Ausführung, Ausmaß der Informationssuche und Verantwortungsgefühl für die Gemeinschaft — unterzogen und Handlungsempfehlungen abgeleitet. In der Analyse der Literatur wird eine steigende Wahrscheinlichkeit einer COVID-19- Impfung bei vorangegangener Influenza-Impfung aufgezeigt. Ärztliches Personal zeigt eine höhere Impfbereitschaft als nicht-ärztliches Personal. Vertrauen in die Impfungen wird in der Analyse aller Studien nach psychologischen Antezedenzien zur Impfentscheidung thematisiert. Das Verantwortungsgefühl für die Gemeinschaft hat einen Einfluss auf die Impfbereitschaft und das Impfverhalten. Dabei sind besonders persönliche Kontakte ein Grund, sich für eine Impfung zu entscheiden. Personal in medizinischen Einrichtungen sollte als eine heterogene Gruppe mit unterschiedlichen Beweggründen für oder gegen Impfungen wahrgenommen werden. Zielgruppenspezifische Kampagnen und Interventionen können Bedarfe und Hemmnisse dieser Gruppen aufgreifen, um in diesem gesellschaftlich wichtigen Tätigkeitsbereich die Impfbereitschaft zu steigern.

description: We test the predictions of the L-functions Ratios Conjecture for the family of cuspidal newforms of weight k and level N, with either k fixed and N --> oo through the primes or N=1 and k --> oo. We study the main and lower order terms in the 1-level density. We provide evidence for the Ratios Conjecture by computing and confirming its predictions up to a power savings in the family's cardinality, at least for test functions whose Fourier transforms are supported in (-2, 2). We do this both for the weighted and unweighted 1-level density (where in the weighted case we use the Petersson weights), thus showing that either formulation may be used. These two 1-level densities differ by a term of size 1 / log(k^2 N). Finally, we show that there is another way of extending the sums arising in the Ratios Conjecture, leading to a different answer (although the answer is such a lower order term that it is hopeless to observe which is correct).

All Roads Lead to Nemea: Physical Evidence for Ancient Roads in the Territory of Kleonai in the Northeastern Peloponnesos

description: This paper presents physical evidence for three ancient Greek roads in the territory which belonged to the polis of Kleonai in the northeastern Peloponnesos; thirty-three discrete road sections are documented, consisting of over sixty segments of wheel ruts and associated features such as aqueducts, retaining walls, and quarries. These roads all appear to represent local alternatives on the first portion of an important route branching off of the Corinth-Argos road at Kleonai and leading west via Nemea. Based on autopsy of the region, the reports of early travelers, likely destinations, and potential roadside features, an additional circumstantial case is made that each road had multiple branches which can be plausibly reconstructed and shown to have had diverse functions. The multiplicity of roads presented here underscores both the importance of access through Kleonaian territory for interstate travel in the Peloponnesos and the ability of a moderately sized polis to maintain and construct roads for local purposes. In the process of documenting these roads, the notion of a standard 1,40 m axle width for Greek roads is challenged and the importance of autopsy for the study of local Greek roads is stressed; ultimately, a reconstruction of the Kleonai’s complex local road network is advanced which enhances the image of the polis as controlling the hub of an important crossroads of direct routes through the Peloponnesos and underscores the benefit of the city’s topographical position to its long-time ally Argos.

description: Breast cancer has become a symbol of tremendous concern in the modern world, as it is one of the major causes of cancer mortality worldwide. In this regard, breast ultrasonography images are frequently utilized by doctors to diagnose breast cancer at an early stage. However, the complex artifacts and heavily noised breast ultrasonography images make diagnosis a great challenge. Furthermore, the ever-increasing number of patients being screened for breast cancer necessitates the use of automated end-to-end technology for highly accurate diagnosis at a low cost and in a short time. In this concern, to develop an end-to-end integrated pipeline for breast ultrasonography image classification, we conducted an exhaustive analysis of image preprocessing methods such as K Means++ and SLIC, as well as four transfer learning models such as VGG16, VGG19, DenseNet121, and ResNet50. With a Dice-coefficient score of 63.4 in the segmentation stage and accuracy and an F1-Score (Benign) of 73.72 percent and 78.92 percent in the classification stage, the combination of SLIC, UNET, and VGG16 outperformed all other integrated combinations. Finally, we have proposed an end to end integrated automated pipelining framework which includes preprocessing with SLIC to capture super-pixel features from the complex artifact of ultrasonography images, complementing semantic segmentation with modified U-Net, leading to breast tumor classification using a transfer learning approach with a pre-trained VGG16 and a densely connected neural network. The proposed automated pipeline can be effectively implemented to assist medical practitioners in making more accurate and timely diagnoses of breast cancer.

description: We investigate the susceptibility of long-range ordered phases of two-dimensional dry aligning active matter to population disorder, taken in the form of a distribution of intrinsic individual chiralities. Using a combination of particle-level models and hydrodynamic theories derived from them, we show that while in finite systems all ordered phases resist a finite amount of such chirality disorder, the homogeneous ones (polar flocks and active nematics) are unstable to any amount of disorder in the infinite-size limit. On the other hand, we find that the inhomogeneous solutions of the coexistence phase (bands) may resist a finite amount of chirality disorder even asymptotically.

description: We present an analysis of the Far Ultraviolet Spectroscopic Explorer ({\it{FUSE}}) spectra of the little-known southern nova-like BB Doradus. The spectrum was obtained as part of our Cycle 8 {\it FUSE} survey of high declination nova-like stars. The FUSE spectrum of BB Dor, observed in a high state, is modeled with an accretion disk with a very low inclination (possibly lower than 10deg). Assuming an average WD mass of 0.8 solar leads to a mass accretion rate of 1.E-9 Solar mass/year and a distance of the order of 650 pc, consistent with the extremely low galactic reddening in its direction. The spectrum presents some broad and deep silicon and sulfur absorption lines, indicating that these elements are over-abundant by 3 and 20 times solar, respectively.

Automatic-repeat-request protocols for data communication networks
Creators: name: Chang, Yet Keung
Publisher: name: University of British Columbia
Year: 2010

description: The performances of a number of Automatic-Repeat-Request (ARQ) protocols are compared on the basis of the expected wasted time per message incurred over random-error and Rayleigh fading channels. These include the standard Stop-And-Wait, Go-Back-N, and Selective-Repeat schemes. The reductions in expected wasted times achievable through the use of forward-error-correction (FEC) are demonstrated. It is found that in general, substantial improvements in performance can be obtained by using FEC. A new ARQ protocol proposed by Weldon is studied. It is shown that the throughput of Weldon's scheme can be increased by allowing multiple copies of a new data block to be sent. In order to maximize the throughput in Weldon's scheme, a number of parameters need to be selected optimally. An efficient method for choosing these parameters is obtained by exploiting the structure of a simplified expression for the throughput. The problem of the optimal block length that minimizes the expected wasted time per message is also considered. An exact analysis of the optimal block length is developed for the Stop-And-Wait scheme using an end-of-message character in the last block of a message. The optimal block length is a function of average message length, channel error rate, overhead per packet, acknowledgement delay and transmission rate. It is found that the optimal block length converges to a constant value when the average message length becomes large. Finally, the performance of an algorithm that computes the optimal block length in an adaptive way is examined.

description: The following thesis tries to evaluate the Rückführungsverbesserungsgesetz (repatriation improvement law), that came into force at the start of 2024, from a social workers perspective, focusing on the changes affecting deportation detention. The thesis begins with an analysis of the historical context of german migration laws and the evolution of deportation detention in Germany. After that the thesis focuses on the current situation in refugee camps and deportation detentions by analysing three different qualitative studies that focused on the realities of asylum seekers in Germany. This is followed by an analysis of the new changes within the RüFüVerG and statements of multiple NGOs referring to those changes. At the end the thesis combines the results of the former analysis with different relevant theories of social work and tries to complete the social worker's perspective on the RüFüVerG. Here by it emphasizes the duty of social work to actively engage in public discourse, include an antirascist agenda in its selfdefinition, and develop strategies in cooperation with volunteers and activist groups that guarantee the usage of all possible means to help those who are in danger of deportation or deportation detention.

description: Many fields have been affected by the introduction of concepts such as sensors, industry 4.0, internet of things, machine learning and artificial intelligence in recent years. As a result of the interaction of cyber physical systems with these concepts, digital twin model has emerged. The concept of digital twin has been used in many areas with its emergence. The use of this model has made significant gains, especially in decision making processes. The gains in decision making processes contribute to every field and cause changes in terms of cost. In this study, the historical development of the concept of digital twin has been mentioned and general information about the usage areas of digital twin has been given. In the light of this information, the cost effect of the digital twin model, therefore its appearance from the cost accounting window and its use as a cost reduction method were evaluated. This study was carried out in order to shed light on the studies with the insufficient resources in the Turkish literature and the cost accounting perspective.

description: Being able to quantify the level of coherent control in a proposed device implementing a quantum information processor (QIP) is an important task for both comparing different devices and assessing a device's prospects with regards to achieving fault-tolerant quantum control. We implement in a liquid-state nuclear magnetic resonance QIP the randomized benchmarking protocol presented by Knill et al (PRA 77: 012307 (2008)). We report an error per randomized $\fracπ{2}$ pulse of $1.3 \pm 0.1 \times 10^{-4}$ with a single qubit QIP and show an experimentally relevant error model where the randomized benchmarking gives a signature fidelity decay which is not possible to interpret as a single error per gate. We explore and experimentally investigate multi-qubit extensions of this protocol and report an average error rate for one and two qubit gates of $4.7 \pm 0.3 \times 10^{-3}$ for a three qubit QIP. We estimate that these error rates are still not decoherence limited and thus can be improved with modifications to the control hardware and software.

description: The virtual reality documentary produced by this study will raise awareness about the present condition of PWD in the information age and how opportunities for them are hindered through certain factors. In addition, the documentary may have an indirect benefit for all PWD by inspiring ICT initiatives to further help PWD in accessing multimedia products. For instance, an improvement to Assistive Technologies (AT) will greatly help in narrowing the disability divide and providing more ICT-related opportunities for PWD. While the study focuses on PWD, it can also help people without disabilities by realizing how important ICT access is. Therefore, maximizing their potentials in the information age knowing that they are able enough to do certain works.

description: We explore the phenomenology of Kaluza-Klein (KK) dark matter in very general models with universal extra dimensions (UEDs), emphasizing the complementarity between high-energy colliders and dark matter direct detection experiments. In models with relatively small mass splittings between the dark matter candidate and the rest of the (colored) spectrum, the collider sensitivity is diminished, but direct detection rates are enhanced. UEDs provide a natural framework for such mass degeneracies. We consider both 5-dimensional and 6-dimensional non-minimal UED models, and discuss the detection prospects for various KK dark matter candidates: the KK photon $γ_1$, the KK $Z$-boson $Z_1$, the KK Higgs boson $H_1$ and the spinless KK photon $γ_H$. We combine collider limits such as electroweak precision data and expected LHC reach, with cosmological constraints from WMAP, and the sensitivity of current or planned direct detection experiments. Allowing for general mass splittings, we show that neither colliders, nor direct detection experiments by themselves can explore all of the relevant KK dark matter parameter space. Nevertheless, they probe different parameter space regions, and the combination of the two types of constraints can be quite powerful. For example, in the case of $γ_1$ in 5D UEDs the relevant parameter space will be almost completely covered by the combined LHC and direct detection sensitivities expected in the near future.

description: Medical conditions and cases are growing at a rapid pace, where physical space is starting to be constrained. Hospitals and clinics no longer have the ability to accommodate large numbers of incoming patients. It is clear that the current state of the health industry needs to improve its valuable and limited resources. The evolution of the Internet of Things (IoT) devices along with assistive technologies can alleviate the problem in healthcare, by being a convenient and easy means of accessing healthcare services wirelessly. There is a plethora of IoT devices and potential applications that can take advantage of the unique characteristics that these technologies can offer. However, at the same time, these services pose novel challenges that need to be properly addressed. In this article, we review some popular categories of IoT-based applications for healthcare along with their devices. Then, we describe the challenges and discuss how research can properly address the open issues and improve the already existing implementations in healthcare. Further possible solutions are also discussed to show their potential in being viable solutions for future healthcare applications

description: Σκοπός της εργασίας αυτής, ήταν να γίνει μια βιβλιογραφική ανασκόπηση σε σχέση με ότι αφορά την οργανοληπτική αξιολόγηση των αποσταγμάτων. Αρχικά έγινε μια σύντομη περιγραφή της κατηγορίας αυτών των αλκοολούχων ποτών όπως επίσης και των βασικών μεθόδων παρασκευής τους, με παραδείγματα ποτών, ανά τεχνολογία παρασκευής - τύπο απόσταξης. Ακολούθως έγινε αναφορά στον τομέα της οργανοληπτικής αξιολόγησης και στις ανθρώπινες αισθήσεις, με αναφορά επίσης, στις βασικές κατηγορίες μεθόδων οργανοληπτικής αξιολόγησης που χρησιμοποιούνται για την οργανοληπτική αξιολόγηση των ποτών. Τέλος έγινε η επισκόπηση των μεθόδων που έχουν χρησιμοποιηθεί στην οργανοληπτική αξιολόγηση των αποσταγμάτων μέχρι τώρα, και με ιδιαίτερη μνεία στις εφαρμογές που αφορούν τον ποιοτικό έλεγχο και την αξιολόγηση σε διαφορετικά σημεία της παραγωγικής διαδικασίας. Διαχρονικά οι μέθοδοι διάκρισης έχουν χρησιμοποιηθεί ευρέως σε αυτήν την κατηγορία ποτών, η περιγραφική ανάλυση όμως αποτελεί μια από τις πιο συχνά χρησιμοποιούμενες διαδικασίες. Η έρευνα έδειξε ότι ενώ δεν έχουν γίνει πολύ μεγάλες αλλαγές στα εργαλεία που χρησιμοποιούνται στην αισθητηριακή αξιολόγηση των αποσταγμάτων, οι γενικότερες νέες τάσεις στην οργανοληπτική επιστήμη, εφαρμόζονται και σε αυτήν την κατηγορία ποτών. Ταυτόχρονα, πιο εξειδικευμένες προσεγγίσεις όπως η μέθοδος Carmer Spirits Tasting Enhancement Method διαφαίνονται ως υποσχόμενες για βελτιωμένα αποτελέσματα. Γενικά υπάρχει πληθώρα προοπτικών ανάπτυξης στις μεθόδους που χρησιμοποιούνται σε αυτήν την κατηγορία ποτών, και θα μπορούσε να επιτευχθεί είτε με συνδυασμό των υπαρχόντων μεθόδων είτε με δημιουργία εντελώς νέων.

description: For an equivariant Morse stratification which contains a unique open stratum, we introduce the notion of equivariant antiperfection, which means the difference of the equivariant Morse series and the equivariant Poincare series achieves the maximal possible value (instead of the minimal possible value 0 in the equivariantly perfect case). We also introduce a weaker condition of local equivariant antiperfection. We prove that the Morse stratification of the Yang-Mills functional on the space of connections on a principal U(n)-bundle over a connected, closed, nonorientable surface is locally equivariantly Q-antiperfect when the rank n=2,3; we propose that it is actually equivariantly Q-antiperfect when n=2,3. Our proposal yields formulas of G-equivariant Poincare series of the representation variety of flat G-connections for the nonorientable surface where G=U(2), SU(2), U(3), SU(3). Our rank 2 formulas agree with formulas proved by T. Baird in arXiv:0806.1975. Baird verified our conjectural rank 3 formulas when the nonorientable surface is the real projective plane or the Klein bottle (arXiv:0901.1604); he proved our conjectural U(3) formula for any closed nonorientable surfaces by establishing equivariant Q-antiperfection in this case (arXiv:0902.4581).

The identification, characterization, and utilization of the ropy lactic streptococci strains and their extracellular excretion
Creators: name: Macura, Dragan Mirkov

description: Traditional cultured milk products have been a source of beneficial lactic acid bacteria whose potential ls constantly being exploited in health and nutrition by modern scientists. One such source is the Scandinavian ropy sour milk, whose constituent microflora produces a unique extracellular excretion which prevents syneresis and graininess, and produces a thicker, smoother, and creamier product than normal sour milk. The industrial potential of these bacteria lies in that they could be used in modern cultured dairy products instead of the bacterial and plant gum stabilizers, or extra butterfat, which are currently used to alter the rheological properties. However, when grown in pure culture, these bacteria gradually lose their ropy character, indicating culture instability. This research project attempted to provide the basic information needed to control the ropy cultures so that reliable ropiness can be assured, and thus large scale industrial applications be made possible. It described the growth characteristics of four ropy isolates, identified their species, isolated and characterized the viscous material produced by one of the ropy isolates, investigated the antimicrobial activity against the major milk spoilage bacteria, studied the compatibility of one ropy strain with buttermilk starter bacteria, and demonstrated the beneficial contribution to the viscosity of commercial buttermilk by this ropy strain. It was found that of four pure culture ropy isolates, one (LLF) was a ropy variant of S. lactls, previously named S. lactis longi. The remaining three (L416, 701 and 705) were, thus far unnamed, variants of S. cremoris, with a suggested name S. cremoris longi. Very good ropiness was produced in liquid milk, neutralized cheese whey, M 17 medium of Terzaghi and Sandine (1975), and a complex casein digest medium, as well as on tomato juice agar and skim milk agar. The culture instability was found to be due to the serial culture transferring, and due to the prolonged product incubation at growth temperature. The analyses of the viscous material showed that it was composed of 47% total protein, 20% methylpentoses, 9.3% protein-bound hexoses, 2.8% sialic acids, and no hexosamines. The rest of the molecle remains to be identified. The ropy culture L416 was found to be inhibitory to ATCC strains of E. coli, S. aureus, and to P. fluorescens biotype A, while it showed no deleterious effects against the standard bacteria of buttermilk starter. Addition of the ropy culture to the commercial buttermilk starter resulted in significant contribution ([sup α] ≤ 0.05) to the equilibrium apparent viscosity, and the consistency of the product.
