description: Από την ανάλυση που προηγήθηκε, καθίσταται σαφές, ότι η κρίση περί την ύπαρξη μεταβίβασης επιχείρησης απαιτεί ιδιαίτερη προσοχή από τον εφαρμοστή του Δικαίου, καθώς συνεπάγεται την εφαρμογή σημαντικών προστατευτικών διατάξεων για τους εργαζομένους της μεταβιβαζόμενης επιχείρησης.Στα πλαίσια της κατά τα ανωτέρω παρεχόμενης προστασίας, εντάσσεται και η υποχρέωση του διαδόχου εργοδότη να τηρεί τους όρους των σ.σ.ε., αφού με τον τρόπο αυτό προστατεύεται η διατήρηση του περιεχομένου των εργασιακών σχέσεων, ώστε να μην καθίσταται εξαιτίας της μεταβίβασης δυσχερέστερη η θέση του μισθωτού. Η εφαρμογή του άρθρου 4 § 2 του π.δ. 178/2002 που αφορά στην διατήρηση των όρων των σ.σ.ε., είναι σχετικά απλή όταν αφορά τη μεταβίβαση μιας αυτοτελούς και κλειστής μονάδας, είναι δυνατόν όμως κατά την εφαρμογή της να ανακύψουν διάφορα ζητήματα στις περιπτώσεις συγχώνευσης επιχειρήσεων, όταν σε αυτές (επιχειρήσεις) ίσχυαν διαφορετικές σ.σ.ε. Οι δυσχέρειες αυτές που εμφανίζονται κατά τα ανωτέρω, οι οποίες, καθώς και οι λύσεις αυτών, διεξοδικά αναλύθηκαν ανωτέρω, καταδεικνύουν και τη σημασία της ρύθμισης αυτής, η οποία συμπορεύει απόλυτα με τη γενικότερη φιλοσοφία του εργατικού δικαίου για την προστασία του εργαζομένου ως ασθενέστερου μέρους της εργασιακής σχέσης.
description: The answer to the question, whether or not, there is a business transfer in each case individually, requires a lot of attention, because as a consequence to this verdict, comes the adaptation of important law provisions, which are set for the protection of the employed of the transferred business.Part of the aforementioned protection, is the obligation of the successor employer to keep to the terms of the collective agreement, as in this way the content of the employment is preserved in order to avoid the deterioration of the employee's condition.The use of the art. 4 § 2 of the degree - law 178/2002, which concerns the preservation of the terms of the collective agreement, is rather simple when it concerns the transfer of an autotelic, self-existent unit. The use of the above article can become harder in the case of business amalgamation, in which many difficult matters appear.The problems that appear, aw well aw their solutions, all of which are analytically and intensively mentioned in this paper, show the importance of this regulation, which keeps pace with the main philosophy of labor law for the protection of the employed, who is the weak part of the work relation.

Prekarisierung der Arbeit – internationale Realität oder Schimäre: Zur deutschen Situation und zur Positionierung der EKD
Creators: name: Jähnichen, Traugott
Publisher: name: UB Tübingen
Year: 2015

description: Die Arbeitsmarktentwicklung der letzten fünf Jahre (2007-2012) in der Bundesrepublik Deutschland ist höchst ambivalent zu bewerten. Zwar ist die Arbeitslosigkeit deutlich gesenkt worden, parallel dazu stieg jedoch der Niedriglohnsektor, der ohnehin in den vergangenen zwei Jahrzehnten um rund 50% gewachsen ist, noch einmal an. Insofern ist der Rückgang der Arbeitslosigkeit mit einer Zunahme des Niedriglohnsektors, darunter überdurchschnittlich viele sog. atypische Beschäftigungsverhältnisse, »erkauft« worden. Dieser Bereich bedarf dringend der politischen Regelung, wobei in diesem Beitrag nicht für eine generelle Rücknahme flexibilisierter Arbeitsverhältnisse plädiert wird, sondern die Einführung von Mindestlöhnen – welche inzwischen im Jahr 2014 nach dem Entstehen des vorliegenden Beitrags gesetzlich in Deutschland eingeführt wurden – und eine Neuformatierung des Sozialsystems in Richtung einer Steuerfinanzierung favorisiert werden.

There are some contradictory perspectives in regard to the labor market development of the Federal Republic of Germany in the past five years (2007-2012). Although unemployment has decreased substantially, the low-wage labor market, which has grown by 50% for the last two decades, also expanded during this five year period.
This decrease in unemployment is exchanged at the »cost« of an increase in the low-wage labor market, with an especially significant increase in so-called atypical employment relationships. This labor market urgently requires political regulation. However, this article does not serve the purpose of pleading for a general reduction of flexible employment contracts, but rather, for the introduction of a minimum wage – which Germany officially implemented in 2014, after the article was written. The article also advocates a reorganization of the social security system by the means of tax financing.

description: We discuss a method to construct hadronic scattering and decay amplitudes from Euclidean correlators, by combining the approach of a regulated inverse Laplace transform with the work of Maiani and Testa. Revisiting the original result, we observe that the key observation, i.e. that only threshold scattering information can be extracted at large separations, can be understood by interpreting the correlator as a spectral function, $ρ(ω)$, convoluted with the Euclidean kernel, $e^{- ωt}$, which is sharply peaked at threshold. We therefore consider a modification in which a smooth step function, equal to one above a target energy, is inserted in the spectral decomposition. This can be achieved either through Backus-Gilbert-like methods or more directly using the variational approach. The result is a shifted resolution function, such that the large $t$ limit projects onto scattering or decay amplitudes above threshold. The utility of this method is highlighted through large $t$ expansions of both three- and four-point functions that include leading terms proportional to the real and imaginary parts (separately) of the target observable. This work also presents new results relevant for the un-modified correlator at threshold, including expressions for extracting the $N π$ scattering length from four-point functions and a new strategy to organize the large $t$ expansion that exhibits better convergence than the expansion in powers of $1/t$.

description: Der Aufsatz unternimmt eine sozialethische Analyse und Bewertung des umstrittenen Phänomens der Prekarisierung, indem er den sozialwissenschaftlichen Gehalt des Konzepts erhebt, die Argumente für und gegen die Verwendung im sozialethischen Kontext abwägt und Kriterien der ethischen Bewertung entwirft. In einem Ausblick werden mögliche sozialpolitische Strategien im Umgang mit dem Problem skizziert.

The essay in social ethics tries to scrutinize the controversial phenomenon of precarization. To that end, four steps are taken. In a first chapter, a short overview of the discourse in the social sciences serves to outline the issue at stake. A second chapter argues for the use of the term in social ethical debates. In a third step, ethical cri-teria for the evaluation of precarization are presented. The essay closes with a short outlook on possible social and political strategies to fight or at least soften the consequences of precarization.

description: A method is presented to produce glass-ceramics from a BOF slag glass containing a high amount of iron. The composition design of these unusual glasses, their melting and crystallization behavior, their crystal nucleation kinetics and the micro structures resulting from different thermal treatments are analyzed and discussed. Several compositions were tested, varying the proportions of slag, sand and Na2CO3 in the batch. A batch with a composition (in wt%) of 60 slag, 35 sand, 5 Na2O showed good vitrificability and displayed bulk crystallization after thermal treatment, and was therefore chosen for a more detailed study. Crystallized materials with nanometric microstructures were obtained using suitable treatments. Fracture strength, hardness and chemical resistance tests were performed. A product with fine volumetric crystallization, a high degree of crystallization, having marble-like appearance, improved mechanical strength and suitable chemical durability was obtained. The material may be suitable for floor and wall tile applications in the construction industry.

description: Understanding the origin of stellar masses is a key problem in astrophysics. In the solar neighborhood, the mass distribution of stars follows a seemingly universal pattern. In the centre of the Milky Way, however, there are indications for strong deviations and the same may be true for the nuclei of distant starburst galaxies. Here we present the first numerical hydrodynamical calculations of stars formed in a molecular region with chemical and thermodynamic properties similar to those of warm and dusty circum-nuclear starburst regions. The resulting IMF is top-heavy with a peak at ~ 15 Msun, a sharp turn-down below 7 Msun and a power-law decline at high masses. We find a natural explanation for our results in terms of the temperature dependence of the Jeans mass, with collapse occuring at a temperature of ~ 100 K and an H2 density of a few times 10^5 cm^-3, and discuss possible implications for galaxy formation and evolution.

Die sozialethische Herausforderung aus sozial-diakonischer Sicht
Creators: name: Sigrist, Christoph
Publisher: name: UB Tübingen

description: Die sozialethische Herausforderung aus sozialdiakonischer Sicht orientiert sich am helfenden Handeln als kirchlicher Auftrag. Die diesem Artikel unterlegte und aus eigener, mehr als 20-jähriger pfarramtlicher Tätigkeit genährte Arbeitshypothese geht davon aus, dass prekäre Lebensverhältnisse im alltäglichen gemeindlichen, parochialen Leben kaum oder gar nicht vorkommen. Es wird zu zeigen sein, dass Prekarisierung als Thema in kirchlichen Verlautbarungen und in der Arbeit von diakonischen Einrichtungen und gesamtkirchlichen Diensten durchaus an Gewicht gewinnt, dies gilt jedoch paradoxerweise nicht für das Leben vor Ort. Zugespitzt gesagt: Prekarisierung grenzt Menschen aus kirchlicher Sicht zweifach aus, innerhalb der Gesellschaft und zugleich aus der kirchlichen Institution.

From the perspective of social diakonia, active assistance is the ethical responsibility of the church. The working hypothesis that this paper is based on, and which has been nourished by over 20 years of parish ministry, makes the assumption that precarious living conditions rarely or never occur in everyday parish life. It will be shown that precarization has indeed been gaining in importance as a topic in both church declarations and in the work of diaconal agencies and the church as a whole. This is, paradoxically, not however reflected in local realities. Precarization, more sharply put, marginalizes people doubly from the point of view of the church, both on the part of society and on the part of church institutions.

description: Elastic properties of binary and ternary tellurite glass systems of the composition (in mol%) (100-x) TeO2 - x Nb2O5, and (100-x) TeO2 - 0.5x (Nb2O5 + Li2O) were calculated from the measured densities as well as from longitudinal and shear ultrasonic velocities at room temperature. Ultrasonic velocity measurements were taken at 4 MHz ultrasonic frequency using the pulse echo technique. Elastic moduli, and Debye temperature calculated from experimental data and calculated theoretically using the bond compression model were used to obtain quantitative details about the structure of these glasses. The effect of adding either Nb2O5 alone or Nb2O5 and Li2 on the elastic moduli was investigated in terms of the number of network bonds of the glass systems. The average atomic ring size of the network was also calculated and it was found that it depends on the concentration of the modifiers. The obtained results show that these glasses become more stable and compact when modified with Nb2O5 or with Nb2O5 and Li2O, which increases the elastic moduli in the two systems.
Interactions between colloidal particles induced by polymer brushes grafted onto the substrate

Year: 2006
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We investigate the interaction energy between two colloidal particles on or immersed in nonadsorbing polymer brushes grafted onto the substrate as a function of the separation of the particles by use of self-consistent field theory calculation. Depending on the colloidal size and the penetration depth, we demonstrate an existence of repulsive energy barrier of several $k_{B}T$, which can be interpreted by separating the interaction energy into three parts: colloids-polymer interfacial energy, entropic contribution due to ``depletion zone" overlap of colloidal particles, and entropically elastic energy of grafted chains by compression of particles. The existence of repulsive barrier which is of entirely entropic origin, can lead to kinetic stabilization of the mixture rather than depletion flocculation or phase separation. Therefore, the present result may suggest an approach to control the self-assembling behavior of colloids for the formation of target structures, by tuning the colloidal interaction on the grafting substrate under appropriate selection of colloidal size, effective gravity (influencing the penetration depth), and brush coverage density.

description: Context: We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 RJup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d orbit. Brown dwarfs and massive planets orbiting M dwarfs on short-period orbits are rare, but more have already been discovered than expected from planet formation models. TOI-519 is a valuable addition into this group of unlikely systems, and adds towards our understanding of the boundaries of planet formation. Aims: We set out to determine the nature of the Transiting Exoplanet Survey Satellite (TESS ) object of interest TOI-519 b. Methods: Our analysis uses a SPOC-pipeline TESS light curve from Sector 7, multicolour transit photometry observed with MuSCAT2 and MuSCAT, and transit photometry observed with the LCOGT telescopes. We estimate the radius of the transiting object using multicolour transit modelling, and set upper limits for its mass, effective temperature, and Bond albedo using a phase curve model that includes Doppler boosting, ellipsoidal variations, thermal emission, and reflected light components. Results: TOI-519 b is a substellar object with a radius posterior median of 1.07 RJup and 5th and 95th percentiles of 0.66 and 1.20 RJup, respectively, where most of the uncertainty comes from the uncertainty in the stellar radius. The phase curve analysis sets an upper effective temperature limit of 1800 K, an upper Bond albedo limit of 0.49, and a companion mass upper limit of 14 MJup. The companion radius estimate combined with the Teff and mass limits suggests that the companion is more likely a planet than a brown dwarf, but a brown-dwarf scenario is more likely a priori given the lack of known massive planets in 1 day orbits around M dwarfs with Teff < 3800 K, and the existence of some (but few) brown dwarfs.

description: The contribution of different modes of the Coulomb field to decoherence and to the dynamical breakdown of the time reversal invariance is calculated in the one-loop approximation for non-relativistic electron gas. The dominant contribution was found to come from the usual collective modes in the plasma, namely the zero-sound and the plasmon oscillations. The length scale of the quantum-classical transition is found to be close to the Thomas-Fermi screening length. It is argued that the extension of these modes to the whole Fock-space yield optimal pointer states.

description: Aurivillius ferroelectric $Bi_2WO_6$ (BWO) encompasses a broad range of functionalities, including robust fatigue-free ferroelectricity, high photocatalytic activity, and ionic conductivity. Despite these promising characteristics, an in-depth study on the growth of BWO thin films and ferroelectric characterization, especially at the atomic scale, is still lacking. Here, we report pulsed laser deposition (PLD) of BWO thin films on (001) $SrTiO_3$ substrates and characterization of ferroelectricity using the scanning transmission electron microscopy (STEM) and piezoresponse force microscopy (PFM) techniques. We show that the background oxygen gas pressure used during PLD growth mainly determines the phase stability of BWO films, whereas the influence of growth temperature is comparatively minor. Atomically resolved STEM study of a fully strained BWO film revealed collective in-plane polar off-centering displacement of W atoms. We estimated the spontaneous polarization value based on polar displacement mapping to be about 54 $\pm$ 4 $μC cm^{-2}$, which is in good agreement with the bulk polarization value. Furthermore, we found that pristine film is composed of type-I and type-II domains, with mutually orthogonal polar axes. Complementary PFM measurements further elucidated that the coexisting type-I and type-II domains formed a multidomain state that consisted of 90$°$ domain walls (DWs) alongside multiple head-to-head and tail-to-tail 180$°$ DWs. Application of an electrical bias led to in-plane 180$°$ polarization switching and 90$°$ polarization rotation, highlighting a unique aspect of domain switching, which is immune to substrate-induced strain.

Ion refraction and stress optical coefficients for di- and metasilicate glasses

description: Glasses of the di- and metasilicate stoichiometric composition were melted, with lithium, sodium and potassium being replaced for each other. Additionally, SiO2 and B2O3 glass samples, the DGG standard glass, a float glass and a metaphosphate glass were examined. Molar mass, molar volume and oxygen partial volume were measured and found to increase in the sequence Li < Na < K. While potassium expands the glass network, the lithium ions show a counteracting behavior. The metaphosphate and the pure B2O3 glass are those with the most compact structure (related to one structure unit) and therefore with the lowest values of the studied properties. It was shown quantitatively that the polarizabilities of the nonbridging oxygen atoms are much higher than those of the bridging oxygen atoms. The influence of the cations was usually small. The origin of the small polarizability values of the B2O3 glass may be interpreted in terms of the lack of the nonbridging oxygen atoms and in terms of the denser structure of the oxygen polyhedra as compared with those in the SiO2 glass. The values of the stress-optical coefficients increase from lithium- to sodium- to potassium-dominated glasses, presumably resulting from increasing ion refraction of the nonbridging oxygen atoms. All preloaded samples of the di- and possibly also of the metasilicate composition showed an increase of the stress-optical coefficients with increasing preload at temperatures higher than the glass transformation temperature Tg. The reason is that a certain flow condition of the glass melts is frozen-in.

description: We investigate an action that includes simultaneously original and dual gravitational fields (in the first order formalism), where the dual fields are completely determined in terms of the original fields through axial gauge conditions and partial (non-covariant) duality constraints. We introduce two kinds of matter, one that couples to the original metric, and dual matter that couples to the dual metric. The linear response of both metrics to the corresponding stress energy tensors coincides with Einstein's equations. In the presence of nonvanishing standard and dual cosmological constants a stable solution with a time independent dual scale factor exists that could possibly solve the cosmological constant problem, provided our world is identified with the dual sector of the model.

description: Ιn the first chapter of our study we attempt to show that the scene of theshields possesses a central position in the composition of the Seven against Thebes, while the close relation between the various parts of the play is also discussed. In the second chapter our interest turns upon the dramatic function of the main scene and conclusions are stated in reference to the techniques that the poet adopted in order to achieve the desirable dramatic result. In the third part we examine the dedonomantic power of words, namely the way by which the words predict, prophesy and determine the course of future events. The cledonomantic power of the language as a semiotic system is utilized by Eteocles in his attempt to reverse the negative omens of the emblems of the enemyshields. The reports of the spy and the answers of Eteocles is the topic of the last chapter.

Estimates for solutions of a non-homogeneous neutral equation are also obtained, they are valid on every finite segment, thus describing both asymptotic and transient behavior. For neutral differential equations, exponential estimates are obtained here for the first time. Both the coefficients and the delays are assumed to be measurable, not necessarily continuous functions.

description: Η εργασία εξετάζει τη δράση της Κοσμητείας Εθνικού Τοπίου κ Πόλεων κατά τις δεκαετίες 1950-1960. Η Κοσμητεία ήταν μια επιτροπή, με μέλη επιφανείς αρχιτέκτονες κ πολεοδόμους, όπως οι Δ. Πικιώνης και Αρ. Προβελέγγιος, που είχε ως στόχο την προστασία του αττικού τοπίου από την άναρχη ανοικοδόμηση. Ιδιαίτερη έμφαση δίδεται στον τρόπο με τον οποίο τα μέλη της Κοσμητείας προσέλαβαν το αττικό τοπίο : ως ιερή, προγονική γη που πρέπει πάση θυσία να διαφυλαχθεί. Η εργασία εντάσσεται δηλαδή στη συζήτηση γύρω από την έννοια τοπίο και την πρόσληψή του, επιλέγοντας ως υπόθεση εργασίας την περίπτωση της Κοσμητείας τοπίου. Παρόλο που τελικά οι προσπάθειες της δεν έφεραν αποτέλεσμα το θέμα είναι ιδιαίτερα ενδιαφέρον καθώς αντικατοπτρίζει την κατάσταση της πνευματικής ζωής της Ελλάδας κατά την περίοδο δράσης της Κοσμητείας.
description: The main subject is a committee formed by architects and city planners during the decades 1950-1960 in order to protect what was considered to be a "sacred landscape". The attican landscape. The members of the committeefought against the uncontrolled building which was taking place at the time, quickly transforming into a building craze. This subject falls into the discussion on landscape and its perception, choosing the "National Landscape Committee" as a case-study.

description: The Vector Spectromagnetograph (VSM) instrument has been recording photospheric and chromospheric magnetograms daily since August 2003. Full-disk photospheric vector magnetograms are observed at least weekly and, since November 2006, area-scans of active regions daily. Quick-look vector magnetic images, plus X3D and FITS formated files, are now publicly available daily. In the near future, Milne-Eddington inversion parameter data will also be available and a typical observing day will include three full-disk photospheric vector magnetograms. Besides full-disk observations, the VSM is capable of high temporal cadence area-scans of both the photosphere and chromosphere. Carrington rotation and daily synoptic maps are also available from the photospheric magnetograms and coronal hole estimate images.

description: Using a density dependent quark mass (QMDD) model for strange quark matter, we investigate the effects of non-Newtonian gravity on the properties of strange stars and constrain the parameters of the QMDD model by employing the mass of PSR J0740+6620 and the tidal deformability of GW170817. We find that for QMDD model these mass and tidal deformability observations would rule out the existenceof str ange stars if non-Newtonian gravity effects are ignored. For the current quark masses of $m_{u0}=2.16$ MeV, $m_{d0}=4.67$ MeV, and $m_{s0}=93$ MeV, we find that a strange star can exist for values of the non-Newtonian gravity parameter $g^{2}/μ^{2}$ in the range of 4.58 GeV$^{-2}\leq g^{2}/μ^{2}\leq$ 9.32 GeV$^{-2}$, and that the parameters $D$ and $C$ of the QMDD modelare restricted to 158.3 MeV$\leq D^{1/2}\leq$ 181.2 MeV and $-0.65\leq C \leq -0.12$. It is found that the largest possible maximum mass of a strange star obtained with the QMDD model is $2.42 \, M_{\odot}$, and that the secondary componentof GW190814 with a mass of 2.59_{-0.09}^{+0.08}\, M_{\dot} could not be a static strange star. We also find that forthe mass and radius of PSR J0030+0451 given by Riley et al. through the analysis of observational data of NICER, there exists a very tiny allowed parameter space for which strange stars computed for the QMDD model agree with the observations of PSR J0740+6620, GW17 0817 and PSR J0030+0451 simultaneously. However, for the mass and radius given by Miller et al., no such parameter space exist.

description: Self-interference (SI) is considered as a main challenge in full-duplex (FD) systems. Therefore, efficient SI cancelers are required for the influential deployment of FD systems in beyond fifth-generation wireless networks. Existing methods for SI cancellation have mostly considered the polynomial representation of the SI signal at the receiver. These methods are shown to operate well in practice while requiring high computational complexity. Alternatively, neural networks (NNs) are envisioned as promising candidates for modeling the SI signal with reduced computational complexity. Consequently, in this paper, two novel low complexity NN structures, referred to as the ladder-wise grid structure (LWGS) and moving-window grid structure (MWGS), are proposed. The core idea of these two structures is to mimic the non-linearity and memory effect introduced to the SI signal in order to achieve proper SI cancellation while exhibiting low computational complexity. The simulation results reveal that the LWGS and MWGS NN-based cancelers attain the same cancellation performance of the polynomial-based canceler while providing 49.87% and 34.19% complexity reduction, respectively.

description: The aim of this study is to clarify the consequences of recent theoretical results for the numerical computation of expectation by the shift method, and in particular to yield sufficient criteria for the existence of speed of convergence of the type `iterated logarithm' in several situations. We deepen the case of the Wiener space because it contains many situations useful in applications.
Metacomprehension Accuracy of Health-Related Information

Subjects: Metacomprehension

Comprehension

description: As part of the production of written information, patient reader panels
 provide judgments of their understanding to evaluate the comprehensibility
 of draft documents. Previous research has suggested i) that there is a
 limited association, on average, between judgments of understanding and
 the comprehension demonstrated in tests of understanding and ii) that
 there is considerable variability between individuals in the direction and
 magnitude of this association. Unfortunately, while previous research
 implies, critically, that reader judgments of comprehensibility have
 limited utility, this research itself is characterized by important
 limitations that prevent firm conclusions.

 This thesis comprises three experimental studies. The study design, method
 of measurement, and the approach to analysis were motivated by a critical
 review of previous research. The specification of participant, text and
 question sample sizes was determined by a novel method of prospective
 study design analysis, evaluating the accuracy and precision in effect
 estimation. The robustness of effect estimates are established through the
 series of empirical replications and in analytical sensitivity checks.

 Across the studies, a weakly positive association between perceived and
 assessed comprehension was found across individuals, on average.
 Differences in reading ability and background knowledge did not reliably
 influence metacomprehension accuracy. Further, metacomprehension
 judgements were similarly predictive of performance on comprehension
 questions that targeted more versus less semantically central information.
 In contrast, metacomprehension judgements targeting specific ideas within
 texts were more predictive of understanding.

 The findings of this thesis indicate that metacomprehension judgements are
 not a gold-standard method of evaluation: judgements show some predictive
 validity of comprehension outcomes, yet provide little insight into
 whether critical elements of the documents are sufficiently understood.
 Overall, whilst situated within an applied context, the present research
 contributes more widely to the metacomprehension literature, making clear
 the need for a shift from traditional analytical approaches, in addition
 to greater theoretical precision.

description: Η ψυχολογία του Αριστοτέλη, αναφέρεται στην φύση της ψυχής και στις λειτουργίες της, εφαρμόζοντας το δυναμικό σχήμα της "δυνάμει" και της "εν ενεργεία" κατάστασης, που χαρακτηρίζει όλη την φιλοσοφία του. Το σώμα έχει "δυνάμει" ζωή και περνάει στην "εν ενεργεία" κατάστασή του, στην πραγμάτωση δηλ. των λειτουργιών του ως σώμα με ζωή, μόνο όταν προσλάβει την ουσιαστική του μορφή, δηλ. την ψυχή. Η ψυχή ορίζεται ως "η πρώτη εντελέχεια σώματος φυσικού οργανισμού". Σ' αυτήν οφείλεται η θρεπτική ικανότητα, η ικανότητα της αίσθησης, η νοητική ικανότητα και η ικανότητα της αίσθησης, η νοητική ικανότητα και η ικανότητα για κίνηση. Ολα αυτά αποτελούν μέρος της ψυχής, που είναι ενωμένα σε μία ιεραρχική σειρά, που έχει ως βάση την θρεπτική ικανότητα και ως κορυφή την νοητική. Η μια προϋποθέτει την άλλη και όλες μαζί είναι ενωμένες σ'ένα σύνολο, το οποίο λειτουργεί αρμονικά. Αναδεικνύεται η διαδικασία της αίσθησης ως μία εσωτερική διαδικασία, που μας φέρνει σ' επαφή με τις επιμέρους καταστάσεις και με την ταυτόχρονη δράση πολλών λειτουργιών που σχετίζονται με τις αισθήσεις και που με την βοήθεια του νου περνάμε στην γνώση του καθολικού, δηλ. στην βέβαιη γνώση των πραγμάτων.
description: Aristotle's psychology, refers to the nature of soul (psyche") and its functions, enforced to the dynamic shape of "potential" and " "in action" condition of the things. The body has "potential" life and pass to "in action" condition, in the realise of all of his functions, like body with life, only when takes on his essential form, namely the soul. With the help of the soul ("psyche"), there are the skill of food, the skill of sense, the mental skill and the skill of movement. All these are parts of the soul, which are connected in one "line". In the beginning of this "line" is the skill of food and in the end is the mental skill. One of these skills presupposes the other and all together are connected in one entirety, which functions in harmony. The procedure of sence is one internal procedure, and with all the functions of senses and with the help of mind, we "pass" to the knowledge of everything, namely to the surely knowledge of the things.

description: We study the long-time aging dynamics of spin-glass models with two-spin interactions by performing a Renormalization Group transformation on the time variable in the non-equilibrium dynamical generating functional. We obtain the RG equations and find that the flow converges to an exact fixed point. We show that this fixed point is invariant under reparametrizations of the time variable. This continuous symmetry is broken, as evidenced by the fact that the observed correlations and responses are not invariant under it. We argue that this gives rise to the presence of Goldstone modes, and that those Goldstone modes shape the behavior of fluctuations in the nonequilibrium dynamics.

description: Dalitz decays of $ω$ and $ρ$ mesons, $ω\to π^0γ^*\toπ^0 e^+e^-$ and $ρ^0\to π^0γ^*\toπ^0 e^+e^-$, produced in $pp$ collisions are calculated within a covariant effective meson-nucleon theory. We argue that the $ω$ transition form factor $F_{ω\to π^0γ^*}$ is experimentally accessible in a fairly model independent way in the reaction $pp \to pp π^0 e^+ e^-$ for invariant masses of the $π^0 e^+ e^-$ subsystem near the $ω$ pole. Numerical results are presented for the intermediate energy kinematics of envisaged HADES experiments.

description: An effective family of spectral curves appearing in Hitchin fibrations is determined. Using this family the moduli spaces of stable Higgs bundles on an algebraic curve are embedded into the Sato Grassmannian. We show that the Hitchin integrable system, the natural algebraically completely integrable Hamiltonian system defined on the Higgs moduli space, coincides with the KP equations. It is shown that the Serre duality on these moduli spaces corresponds to the formal adjoint of pseudo-differential operators acting on the Grassmannian. From this fact we then identify the Hitchin integrable system on the moduli space of Sp(2m)-Higgs bundles in terms of a reduction of the KP equations. We also show that the dual Abelian fibration (the SYZ mirror dual) to the Sp(2m)-Higgs moduli space is constructed by taking the symplectic quotient of a Lie algebra action on the moduli space of GL-Higgs bundles.
