description: We have studied the effect of substrate-induced strain on the properties of the hole-doped manganite (La$_{1-y}$Pr$_{y}$)$_{0.67}$Ca$_{0.33}$MnO$_{3}$ ($y$ = 0.4, 0.5 and 0.6) in order to distinguish between the roles played by long-range strain interactions and quenched atomic disorder in forming the micrometer-scale phase separated state. We show that a fluid phase separated (FPS) state is formed at intermediate temperatures similar to the strain-liquid state in bulk compounds, which can be converted to a metallic state by applying an external electric field. In contrast to bulk compounds, at low temperatures a strain stabilized ferromagnetic metallic (FMM) state is formed in the $y$ = 0.4 and 0.5 samples. However, in the $y$ = 0.6 sample a static phase separated (SPS) state is formed similar to the strain-glass phase in bulk compounds. Hence, we show that long-range strain interaction plays a dominant role in forming the micrometer-scale phase separated state in manganite thin films.

description: Wer heute eine Inselreise unternimmt, der sehnt sich zumeist danach, den Alltag hinter sich zu lassen, Entspannung und Erholung zu finden. Dass eine Inselfahrt jedoch in physischer wie in kognitiver Hinsicht durchaus auch mühsam und anstrengend zu sein vermag, offenbart der Blick auf literarische Inseldarstellungen vom Mittelalter bis in die Gegenwart. Erweist sich die Insel selbst in der mittelalterlichen Literatur als Erkenntnisort, der einen hohen Grad an Sensibilität für Raumformen erfordert, so gerät die Insel im Laufe der Jahrhunderte zunehmend zu einem Signalraum, der utopische und dystopische Gehalte in sich aufnimmt. Die Suche nach Idealität, nach Entwicklung und nach Sinn führt den Reisenden dabei immer wieder an die Grenzen seiner Erfahrungswelt, die sich insbesondere durch technische und wissenschaftliche Neuerungen stetig erwei-tert. Inseln sind infolge dieser Fortschritte nicht nur auf einer horizontalen, sondern auch auf einer vertikalen Raumachse verortet und erobern sogar die Dimension der Zeit. Anhand ausgewählter literarischer und filmischer Inseldarstellungen lassen sich die Reise der Insel vom Mittelalter bis in die Gegenwart, der Wandel ihrer Codierungen sowie die Relation von Insel und Mensch nachvollziehen.

description: Kaum ein touristischer Raum wird so sehr idealisiert wie der Strand, denn an dessen positiver Konnotation arbeitet die Werbeindustrie stetig und intensiv mit. Sie trägt dazu bei, den Traum vom sonnigen, sandigen Paradies aufrechtzuerhalten und generationenübergreifend zu verbreiten. Am Beispiel der mallorquinischen Stranddarstellungen in Reisekatalogen des Unternehmens Scharnow-Reisen lassen sich die Entwicklungslinien der Strandbilder von den Anfängen des Pauschaltourismus bis hin zu modernen ‚Paradiesen‘ eines massenhaften Tourismus aufzeigen. Im folgenden Beitrag wird exemplarisch auf die Darstellung des ‚Sonnenbadens‘ in den 1960er Jahren eingegangen und untersucht, wie das Reiseunternehmen mallorquinische Strände zwischen 1963 und 1972/73 diesbezüglich inszeniert, welche Requisiten zum Einsatz kommen und welche Sehnsüchte der damaligen deutschen Gesellschaft sich daraus ablesen lassen.

description: The group delay incurred by an optical wave packet depends on its path length. Therefore, when a wave packet is obliquely incident on a planar homogeneous slab, the group delay upon traversing it inevitably increases with the angle of incidence. Here we confirm the existence of isochronous `space-time' (ST) wave packets: pulsed beams whose spatio-temporal structure enables them to traverse the layer with a fixed group delay over a wide span of incident angles. This unique behavior stems from the dependence of the group velocity of a refracted ST wave packet on its angle of incidence. Isochronous ST wave packets are observed in slabs of optical materials with indices in the range from 1.38 to 2.5 for angles up to $50^{\circ}$ away from normal incidence.

Decoupling Spurious Baryon States in the 1/N_c Expansion of QCD

description: We identify ``spurious'' states in meson-baryon scattering, those that appear in QCD for N_c > 3 but decouple for N_c = 3. The key observation is that the relevant flavor SU(3) Clebsch-Gordan coefficients contain factors of 1 - 3/N_c. We show that this method works even if SU(3) is badly broken. We also observe that resonant scattering poles lying outside naive quark model multiplets are not necessarily large N_c artifacts, and can survive via configuration mixing at N_c = 3.

description: We study a SU(2) gauge theory with a classical complex modulus. Introducing a chemical potential for a conserved modulus hypercharge causes it to become unstable and start condensing. We show that the modulus condensation in turn generates homogeneous but anisotropic non-abelian field strength condensates. The existence of a stable vacuum at the end point of the condensation process depends on a modulus representation under the gauge group. For a modulus in the fundamental representation, the global vacuum of the theory is a state both with the rotational symmetry and the electromagnetic U(1) being spontaneously broken. In other words, the system describes an anisotropic superconducting medium. We further explore the landscape of vacua of this theory and identify metastable vacua with an abnormal number of Nambu-Goldstone bosons. The SO(2) symmetry of these vacua corresponds to locking gauge, flavor, and spin degrees of freedom. There are also metastable SO(3) rotationally invariant vacua. For a modulus in the adjoint representation, we show that the theory does not have stable vacua with homogeneous anisotropic non-abelian field strength condensates, although there are metastable vacua. The reason of that is connected with a larger number of the physical components of the modulus in the case of the adjoint representation as compared to the fundamental one.

description: Sharing Economy, kollaborativer Konsum, Nutzen statt Besitzen – diese Bezeichnungen beschreiben den gemeinsamen, meist kostenlosen Gebrauch von Dingen und gewinnen innerhalb des Konsumbereichs seit einigen Jahren an Popularität. Doch wie lässt sich diese Entwicklung konkret gesellschaftlich verorten? Der vorliegende Beitrag gewährt mithilfe einer teilnehmenden Beobachtung Einblicke in die Praktiken und Strukturen einer Kleidertauschveranstaltung in Regensburg und deckt mittels eines Leitfadeninterviews vor allen Dingen individuelle Verhaltensweisen sowie Wahrnehmungsweisen über Konsum und Überfluss auf. Dabei stellt sich heraus, dass eine soziale Innovation wie das Kleidertauschen nicht einfach nur als nebensächlicher Zeitvertreib, sondern als komplexer Ausdruck sozialer sowie kultureller Phänomene dient.

Multivalley dark solitons in multicomponent Bose-Einstein condensates with repulsive interactions

description: We obtain multivalley dark soliton solutions with asymmetric or symmetric profiles in multicomponent repulsive Bose-Einstein condensates by developing the Darboux transformation method. We demonstrate that the width-dependent parameters of solitons significantly affect the velocity ranges and phase jump regions of multivalley dark solitons, in sharp contrast to scalar dark solitons. For double-valley dark solitons, we find that the phase jump is in the range $[0,2π]$, which is quite different from that of the usual single-valley dark soliton. Based on our results, we argue that the phase jump of an $n$-valley dark soliton could be in the range $[0,nπ]$, supported by our analysis extending up to five-component condensates. The interaction between a double-valley dark soliton and a single-valley dark soliton is further investigated, and we reveal a striking collision process in which the double-valley dark soliton is transformed into a breather after colliding with the single-valley dark soliton. Our analyses suggest that this breather transition exists widely in the collision processes involving multivalley dark solitons. The possibilities for observing these multivalley dark solitons in related Bose-Einstein condensates experiments are discussed.
Reproductive and natal homing of marine threespine sticklebacks (Gasterosteus aculeatus)
Creators: name: Saimoto, Ron Shigeo
Publisher: name: University of British Columbia
Year: 2009

description: Natal and reproductive homing were investigated in marine and anadromous populations of threespine sticklebacks (Gasterosteus aculeatus). Three breeding sites within 1 km2of Pender Harbour, British Columbia, were examined. For the reproductive homing experiment (displacement of adults from a breeding site), female sticklebacks from Oyster Lagoon, Salt Lagoon, and Paq Creek were marked and displaced (.15 - 1.0 km) to three release sites. These displaced females predominately returned to their original breeding sites, although there was some straying. The proportion of marked fish recaptured at their original breeding site ranged from 0.81 to 1.00. The anadromous population (Paq Creek) showed the strongest tendency to return (0.99 - 1.00). Natal homing (return to birth site) was investigated in the Oyster Lagoon population. Young of the year were marked on three different outmigrations (April 1991, August 1991, and April 1992): 0.85 %, 3.5% and 5.2 % respectively, were recaptured as adults during the 1992 breeding season at Oyster Lagoon. Relatively short stays outside the lagoon (2 - 4 months), by juveniles that overwintered in Oyster Lagoon, resulted in strong natal homing and weak straying to adjacent breeding sites; however, straying to Salt Lagoon increased with longer stays outside the lagoon. This suggests an inverse relationship between the length of time spent out of the lagoon and the accuracy of homing. Straying to the anadromous breeding site (Paq Creek) remained low for all lengths of stay in the sea (2 - 16 months). This maintained avoidance of Paq Creek suggests that the marine and anadromous populations may be genetically isolated. The level of straying between Salt and Oyster lagoons probably is sufficient to prevent divergence between these adjacent marine populations. Generally however, this study demonstrates both reproductive and natal homing in threespine sticklebacks and, on a larger geographic scale, this natal homing may be sufficient to allow the evolution of inter-population heterogeneity among marine and anadromous populations.
Asymmetric Multipole Plasmon-Mediated Catalysis Shifts the Product Selectivity of CO2 Photoreduction toward C2+ Products

description: Cu/TiO2 is a well-known photocatalyst for the photocatalytic transformation of CO2 into methane. The formation of C2+ products such as ethane and ethanol rather than methane is more interesting due to their higher energy density and economic value, but the formation of C–C bonds is currently a major challenge in CO2 photoreduction. In this context, we report the dominant formation of a C2 product, namely, ethane, from the gas-phase photoreduction of CO2 using TiO2 nanotube arrays (TNTAs) decorated with large-sized (80–200 nm) Ag and Cu nanoparticles without the use of a sacrificial agent or hole scavenger. Isotope-labeled mass spectrometry was used to verify the origin and identity of the reaction products. Under 2 h AM1.5G 1-sun illumination, the total rate of hydrocarbon production (methane + ethane) was highest for AgCu-TNTA with a total CxH2x+2 rate of 23.88 μmol g–1 h–1. Under identical conditions, the CxH2x+2 production rates for Ag-TNTA and Cu-TNTA were 6.54 and 1.39 μmol g–1 h–1, respectively. The ethane selectivity was the highest for AgCu-TNTA with 60.7%, while the ethane selectivity was found to be 15.9 and 10% for the Ag-TNTA and Cu-TNTA, respectively. Adjacent adsorption sites in our photocatalyst develop an asymmetric charge distribution due to quadrupole resonances in large metal nanoparticles and multipole resonances in Ag–Cu heterodimers. Such an asymmetric charge distribution decreases adsorbate–adsorbate repulsion and facilitates C–C coupling of reaction intermediates, which otherwise occurs poorly in TNTAs decorated with small metal nanoparticles.

description: We consider four dimensional heterotic string backgrounds for which supersymmetry is spontaneously broken via the Scherk-Schwarz mechanism on an internal spatial cycle and by finite temperature effects. We concentrate on initially flat backgrounds with N=4 and N=2 amount of supersymmetry. Thermal and quantum corrections give rise to a non-trivial cosmological evolution. We show that these corrections are under control and calculable due to the underlying no-scale structure of the effective supergravity theory. The effective Friedmann-Hubble equation involves a radiation term ~1/a^4 and a curvature term ~1/a^2, whose coefficients are functions of ratio of the gravitino mass scale to the temperature.

description: We analyze the 3D morphology and kinematics of 13 open clusters (OCs) located within 500 pc of the Sun, using Gaia EDR3 and kinematic data from literature. Members of OCs are identified using the unsupervised machine learning method StarGO, using 5D parameters (X, Y, Z, $μ_α\cosδ, μ_δ$). The OC sample covers an age range of 25Myr--2.65Gyr. We correct the asymmetric distance distribution due to the parallax error using Bayesian inversion. The uncertainty in the corrected distance for a cluster at 500~pc is 3.0--6.3~pc, depending on the intrinsic spatial distribution of its members. We determine the 3D morphology of the OCs in our sample and fit the spatial distribution of stars within the tidal radius in each cluster with an ellipsoid model. The shapes of the OCs are well-described with oblate spheroids (NGC2547, NGC2516, NGC2451A, NGC2451B, NGC2232), prolate spheroids (IC2602, IC4665, NGC2422, Blanco1, Coma Berenices), or triaxial ellipsoids (IC2391, NGC6633, NGC6774). The semi-major axis of the fitted ellipsoid is parallel to the Galactic plane for most clusters. Elongated filament-like substructures are detected in three young clusters (NGC2232, NGC2547, NGC2451B), while tidal-tail-like substructures (tidal tails) are found in older clusters (NGC2516, NGC6633, NGC6774, Blanco1, Coma Berenices). Most clusters may be super-virial and expanding. $N$-body models of rapid gas expulsion with an SFE of $\approx 1/3$ are consistent with clusters more massive than $250\rm M_\odot$, while clusters less massive than 250$\rm M_\odot$ tend to agree with adiabatic gas expulsion models. Only six OCs (NGC2422, NGC6633, and NGC6774, NGC2232, Blanco1, Coma Berenices) show clear signs of mass segregation.

description: Many algorithms for visible light positioning (VLP) localization do not consider the shapes of the transmitters, which leads to the impracticality of the algorithm and the low localization accuracy. Therefore, this paper proposes a novel VLP algorithm and addresses the problems in terms of practicality and complexity by using one non-point transmitter based on a monocular. Because the shape of the transmitter is considered, the proposed algorithm is easy for practice and has wide applicability. Besides, it decreases the computation for simple geometric model and expands the coverage for there is a greater chance of receiving signals from one light than that of receiving signals from multiple lights.

description: General orbits of a particle of small mass $μ$ around a Kerr black hole of mass $M$ are characterized by three parameters: the energy, the angular momentum and the Carter constant. The time-averaged rates of change of the energy and the angular momentum can be obtained by computing the corresponding fluxes of gravitational waves emitted by the particle. By contrast, the time-averaged rate of change of the Carter constant cannot be expressed as a flux of gravitational waves. Recently a method to compute this rate of change was proposed by Mino, and we refined it into a simplified form. In this paper we further extend our previous work to give a new formulation without the aid of expansion in terms of a small inclination angle.

description: The goal of the Metadata Automation DREAM Challenge was to develop a tool to automate the annotation of metadata fields and values in structured biomedical data files with the best candidate Common Data Element (CDE) matches from the Cancer Data Standards Registry and Repository (caDSR). We chose to implement our model in Python 3.6 and approached this challenge from the perspective that it was essentially a fuzzy matching problem. Our approach utilizes Scikit-Learn’s TfidfVectorizer class along with a custom n-gram function to vectorize the data. These term frequency - inverse document frequency (TF-IDF) vectors are passed to Scikit-Learn’s Nearest Neighbor class which returns the k nearest CDE neighbors and their associated distance scores for each column header in the biomedical data file. For the returned CDEs with enumerated values, the Levenshtein distances from the observed values in the data to the CDE’s permissible values are computed using Python’s FuzzyWuzzy library. We then use a decision tree approach based on the TF-IDF distance scores and the observed values’ average Levenshtein distance scores to select and rank the top three CDE matches from the set of nearest neighbors for each column header. In this final ranking step, we apply cutoff values to the distance scores to determine when to include ‘NOMATCH’ as one of the three results. Throughout the challenge we experimented with many aspects of the algorithm including modifying the n-gram function, the selection of caDSR fields to include in the TF-IDF vectorization and applying different cutoff values. The final version of our model was arrived at by selecting the features and parameters that maximized the overall score across all the provided test datasets.

description: Surface enhanced Raman scattering (SERS) process results in a tremendous increase of Raman scattering cross section of molecules adsorbed to plasmonic metals and influenced by numerous physico-chemical factors such as geometry and optical properties of the metal surface, orientation of chemisorbed molecules and chemical environment. While SERS holds promise for single molecule sensitivity and optical sensing of DNA sequences, more detailed understanding of the rich physico-chemical interplay between various factors is needed to enhance predictive power of existing and future SERS-based DNA sensing platforms. In this work we report on experimental results indicating that SERS spectra of adsorbed single-stranded DNA (ssDNA) isomers depend on the order on which individual bases appear in the 3-base long ssDNA due to intra-molecular interaction between DNA bases. Furthermore, we experimentally demonstrate that the effect holds under more general conditions when the molecules don't experience chemical enhancement due to resonant charge transfer effect and also under standard Raman scattering without electromagnetic or chemical enhancements. Our numerical simulations qualitatively support the experimental findings and indicate that base permutation results in modification of both Raman and chemically enhanced Raman spectra.

description: Η παρούσα έρευνα αποσκοπεί να καταγράψει τον τρόπο παρουσίασης του αστικού περιβάλλοντος μέσα από τα κείμενα των σχολικών εγχειριδίων της Γλώσσας για την Ε’ και Στ’ Τάξη του Δημοτικού. Συνιστώσες που αφορούν τα αστικά κέντρα, όπως ο αστικός σχεδιασμός, η αστική περιβαλλοντική ρύπανση, το κυκλοφοριακό ζήτημα, η διαχείριση των ενεργειακών πόρων ενός αστικού πυρήνα, η αειφόρος πόλη και οι χώροι πρασίνου μέσα σ’ αυτήν, αναζητήθηκαν στα σχολικά βιβλία της Γλώσσας των δύο τελευταίων τάξεων του Δημοτικού. Η μέθοδος που χρησιμοποιήθηκε για την εκπόνηση της εργασίας είναι η Ανάλυση Περιεχομένου (Content Analysis). Ερευνητικό εργαλείο αποτέλεσε η λίστα ελέγχου, στις κατηγορίες της οποίας, προστέθηκαν υποκατηγορίες. Η επεξεργασία των αποτελεσμάτων έγινε ποσοτικά με τη γραφική τους αναπαράσταση, αλλά και ποιοτικά για τη διεξαγωγή των τελικών συμπερασμάτων της έρευνας. Η εικόνα των αστικών κέντρων μοιάζει περισσότερο με πόλεις περασμένων δεκαετιών. Περιβαλλοντικά ζητήματα ρύπανσης, το θέμα της ενεργειακής κρίσης των σύγχρονων αστικών κέντρων, η παρουσία χώρων πρασίνου, και το όραμα για μία αειφόρο πόλη, πραγματεύονται ελάχιστα στα προς μελέτη κείμενα. Από την άλλη πλευρά, ένα σύγχρονο αστικό περιβάλλον το οποίο προσπαθεί να επιλύσει το κυκλοφοριακό ζήτημα και να φέρει τους πολίτες σε επαφή με τον Πολιτισμό και τις Τέχνες, αποτελεί ένα αξιοσημείωτο, ποιοτικά, δείγμα αναφορών στα προς μελέτη κείμενα.
description: This research aims to record the presentation of the urban environment through the textbooks of Greek Language, which is provided to the students of the fifth and sixth grade of primary school. Component of urban centers, such as city planning, urban environmental pollution, urban transportation, the management of energy resources of an urban core, sustainable city and green parks in it, were searched for at the particular textbooks of Greek Language. The methodology used for this work is the Content Analysis. The research tool was a checklist, in which categories and subcategories were formulated. The collected results were quantified by graphic representation and were analysed for their qualitative characteristics in order the final conclusions of the research to be written. The image of urban centers seems like past decades cities. Environmental pollution issues, the issue of energy crisis of modern urban centers, the presence of green areas, and the vision for sustainable city, are barely presented. On the other hand, a modern urban environment that tries to solve the traffic problem and bring its citizens into contact with Culture and Arts, is a remarkable sample of reports of the studied texts.

description: We update the Standard Model predictions of the anomalous magnetic moment of the muon, a_μ= (g-2)/2, and the value of the QED coupling at the Z-boson mass, incorporating the new e^+e^- \to ππdata obtained by CMD-2 and KLOE, as well as the corrected SND data, and other improvements. The prediction for a_μ=11659180.4 (5.1) \times 10^{-10} is about 3 \times 10^{-10} lower than before, and has a smaller uncertainty, which corresponds to a 3.4σdeviation from the measured value. The prediction for the QED coupling is α(M_Z^2)^{-1}= 128.937 \pm 0.030.

description: The band structure of graphene ribbons with zigzag edges have two valleys well separated in momentum space, related to the two Dirac points of the graphene spectrum. The propagating modes in each valley contain a single chiral mode originating from a partially flat band at band center. This feature gives rise to a perfectly conducting channel in the disordered system, if the impurity scattering does not connect the two valleys, i.e. for long-range impurity potentials. Ribbons with short-range impurity potentials, however, through inter-valley scattering display ordinary localization behavior. The two regimes belong to different universality classes: unitary for long-range impurities and orthogonal for short-range impurities.

description: Η έννοια της συμπεριληπτικής εκπαίδευσης αποτελεί μετεξέλιξη της ιδέας της ένταξης και απάντηση στην αναποτελεσματικότητα της εφαρμογής ενταξιακών προγραμμάτων τα τελευταία χρόνια , στην Ελλάδα αλλά και διεθνώς, που δεν κατάφεραν να ενσωματώσουν ουσιαστικά τον μαθητή με ειδικές εκπαιδευτικές ανάγκες στη γενική εκπαίδευση (Γεωργιάδη, Κουρκουτάς, & Καλύβα, 2007). Οι ίδιοι οι εκπαιδευτικοί φαίνεται να έχουν διαφορετικές απόψεις ως προς την ένταξη/συμπερίληψη όλων των παιδιών στην τάξη. Κάποιοι τη θεωρούν ευεργετική πιστεύοντας ότι η συμμετοχή σε κοινότητες αποτελεί προϋπόθεση για μάθηση και ανάπτυξη. Κάποιοι άλλοι πιστεύουν ότι η συμμετοχή των παιδιών με ειδικές εκπαιδευτικές ανάγκες στις τυπικές τάξεις πιθανώς είναι επωφελής για την κοινωνική τους ζωή, αν το ενδιαφέρον για τη μάθηση είναι δευτερεύον. Υπάρχουν κι αυτοί που εκφράζουν την άποψη ότι συμμετέχοντας οι συγκεκριμένοι μαθητές στην τυπική τάξη παραμελούνται άλλες πιο ειδικές τους ανάγκες (Hansen, 2012). Στόχος της παρούσας έρευνας είναι η συγκριτική διερεύνηση των απόψεων εκπαιδευτικών Α/θμιας γενικής τάξης και Παράλληλης Στήριξης για τη χρησιμότητα (μαθησιακή και κοινωνική) του θεσμού της Παράλληλης Στήριξης σε συγκεκριμένους μαθητές με ειδικές εκπαιδευτικές ανάγκες ή αναπηρίες, που φοιτούν στις τάξεις τους στο γενικό δημοτικό σχολείο.
description: The concept of inclusive education is an evolution of the idea of integration and a response to the inefficiency of applying, in Greece and abroad, accession programs in recent years were unable to effectively integrate the student with special educational needs into the main education (Georgiadis, Kourkoutas & Kaliva, 2007). The teachers themselves seem to have different views on the integration/inclusion of all children into the class. Some consider it beneficial taking the view that the participation in communities constitutes a prerequisite for learning and development. Others believe that the participation of children with special educational needs in common classes is probably beneficial to their social life, in cases where the interest in learning is secondary. There are those who are of the opinion that by such participation in common classes other more special needs of those students are being neglected (Hansen, 2012). The objective of this research is the comparative investigation of the views of the first level education standard class’ and Parallel Support teachers as regards the (learning and social) use of the Parallel Support institution for certain pupils with special educational needs or disabilities, who attend their classes in a common primary school.
Investigating the significance of single and married mothers’ child care arrangements on work/family role balance
Creators: name: Madaisky, Dolores P.

description: The relationship between a mother’s child care arrangements and her work/family role balance has been investigated. Differences between married and single mothers’ child care arrangements and their work/family role balance has also been investigated. Seven hypotheses that phrase these relationships empirically have been postulated. From the Statistics Canada General Social Survey Cycle 5 version (1990) a sub-sample of 504 mothers with children under the age of 5 years was selected. Multiple regression, chi square and ANCOVA procedures were applied. The results indicated that 2 of the 7 hypotheses were significantly supported. In particular, the significant findings suggest that family care, day care and relative care vary negatively on satisfaction and positively on number of hours the respondent works per week (two of the four dependent measures that represented the work/family role balance concept). Also, the results suggested that married mothers suffer from less work/family role imbalance than single mothers. In addition, single and married mothers differed in their use of day care and relative care. The findings were explained by current work/family literature. Work/family role balance was partially explained by the methodological representation. Rather, this theory was used as a guide to further the search for a theoretical framework that incorporates both enhancement and conflict. In addition, an implication for future research is to locate additional variables that exhaustively explain this concept so that work/family role balance may become a theory that can stand up to the most vigorous empirical testing.

description: Data from the Fermilab E835 experiment have been used to study the reaction pbar p -> eta eta pi0 at 5.2 GeV/c. A sample of 22 million six photons events has been analyzed to construct the Dalitz plot containing ~80k eta eta pi0 events. A partial wave analysis of the data has been done. Six f_J-states decaying into eta eta and five a_J-states decaying into eta pi0 are identified in the mass region ~1.3 and 2.4 GeV, and their masses, widths and spins are determined by maximum likelihood analysis of the data. Two f_0 states are identified with the popular candidates for the lightest scalar glueball, f_0(1500) and f_0(1710).

Αφού εξετάστηκαν τα 4 αυτά διαφορετικά συστήματα, μετά από υπολογισμό των ενεργειακών αναγκών του θερμοκηπίου, συγκρίθηκαν στη συνέχεια τα αποτελέσματα από οικονομικής απόψεως, με χρήση της μεθόδου της καθαράς παρούσας αξίας. Αφού βρέθηκε το σύστημα που συμφέρει περισσότερο έναν παραγωγό στο βάθος μιας 15ετίας, τέθηκαν ερωτήματα για περαιτέρω έρευνα.
description: The aim of the present thesis was the comparison of 4 different heating systems of a five acre greenhouse. The four systems were as follows. 1. System using a heating pump and a wind turbine 2. System using a heating pump, a wind turbine and power from an electricity company 3. System using a heating pump and power from an electricity company and 4. System using a conventional heating method (petrol). After the four different systems were examined, having calculated the energy needs of the greenhouse, they were then compared to each other from an economical point of view, using the present net value method. In the end, having found the system that is the most beneficient for the farmer in the span of 15 years, questions regarding further research were raised.
