description: Σκοπός της παρούσας διπλωματικής εργασίας είναι η παρουσίαση, η ανάλυση και η κατανόηση του νευρομάρκετινγκ και του αντίκτυπου που αυτό έχει στην ελληνική οικονομία. Το νευρομάρκετινγκ αποτελεί έναν κλάδο άμεσα συνδεδεμένο με το μάρκετινγκ, το οποίο τις τελευταίες δεκαετίες βρίσκεται σε συνεχή ανάπτυξη σε διεθνές οικονομικό και εμπορικό επίπεδο. Για να επιτευχθεί ο σκοπός αυτός αξιοποιήθηκε η μέθοδος της βιβλιογραφικής ανασκόπησης ερευνών και βιβλιογραφιών που αναπτύσσουν εις βάθος το θέμα. Η μελέτη ξεκινάει με τη παρουσίαση του παραδοσιακού μάρκετινγκ και της στρατηγικής αυτού ως βασικό πυλώνα πάνω στον οποίο στηρίζεται το νευρομάρκετινγκ. Στη συνέχεια προχωράμε σε μια εισαγωγή στην έννοια του νευρομάρκετινγκ. Για να επιτευχθεί αυτό γίνεται αρχικά μια αναλυτική παρουσίαση του ανθρώπινου εγκεφάλου και των λειτουργιών του, ενώ έπεται η παρουσίαση των οφελών, των τεχνικών έρευνας και των στόχων του νευρομάρκετινγκ. Αναφορά γίνεται επίσης και ως προς τα πρακτικά και ηθικά ζητήματα που παρουσιάζονται κατά την άσκηση αυτού πάντα σε συνδυασμό με το μάρκετινγκ και τον ανθρώπινο εγκέφαλο. Στην επόμενη ενότητα της εργασίας αναπτύσσεται η θεωρία συμπεριφοράς καταναλωτή και το πώς αυτή αποκωδικοποιείται ή επηρεάζεται μέσω του νευρομάρκετινγκ παρουσιάζοντας παραδείγματα και διαφορετικές τεχνικές. Τέλος γίνεται η παρουσίαση μέσω παραδειγμάτων του πως και κατά πόσο το νευρομάρκετινγκ έχει μπει για τα καλά στην ελληνική οικονομία και τίθεται το ερώτημα αν αυτό μπορεί να καθορίσει την συμπεριφορά του έλληνα καταναλωτή το 2022 και αν ναι με ποια μέσα και σε ποιο βαθμό.

description: Well characterized sequences of dynamical states play an important role for motor control and associative neural computation in the brain. Autonomous dynamics involving sequences of transiently stable states have been termed associative latching in the context of grammar generation. We propose that generating functionals allow for a systematic construction of dynamical networks with well characterized dynamical behavior, such as regular or intermittent bursting latching dynamics. Coupling local, slowly adapting variables to an attractor network allows to destabilize all attractors, turning them into attractor ruins. The resulting attractor relict network may show ongoing autonomous latching dynamics. We propose to use two generating functionals for the construction of attractor relict networks. The first functional is a simple Hopfield energy functional, known to generate a neural attractor network. The second generating functional, which we denote polyhomeostatic optimization, is based on information-theoretical principles, encoding the information content of the neural firing statistics. Polyhomeostatic optimization destabilizes the attractors of the Hopfield network inducing latching dynamics. We investigate the influence of stress, in terms of conflicting optimization targets, on the resulting dynamics. Objective function stress is absent when the target level for the mean of neural activities is identical for the two generating functionals and the resulting latching dynamics is then found to be regular. Objective function stress is present when the respective target activity levels differ, inducing intermittent bursting latching dynamics. We propose that generating functionals may be useful quite generally for the controlled construction of complex dynamical systems.

description: We present the one-year long observing campaign of SN 2012A which exploded in the nearby (9.8 Mpc) irregular galaxy NGC 3239. The photometric evolution is that of a normal type IIP supernova. The absolute maximum magnitude, with MB = -16.23 +- 0.16 mag. SN2012A reached a peak luminosity of about 2X10**42 erg/s, which is brighter than those of other SNe with a similar 56Ni mass. The latter was estimated from the luminosity in the exponential tail of the light curve and found to be M(56Ni) = 0.011 +-0.004 Msun. The spectral evolution of SN 2012A is also typical of SN IIP, from the early spectra dominated by a blue continuum and very broad (~10**4 km/s) Balmer lines, to the late-photospheric spectra characterized by prominent P-Cygni features of metal lines (Fe II, Sc II, Ba II, Ti II, Ca II, Na ID). The photospheric velocity is moderately low, ~3X10**3 km/s at 50 days, for the low optical depth metal lines. The nebular spectrum obtained 394 days after the shock breakout shows the typical features of SNe IIP and the strength of the [O I] doublet suggests a progenitor of intermediate mass, similar to SN 2004et (~15 Msun). A candidate progenitor for SN 2012A has been identified in deep, pre-explosion K'-band Gemini North (NIRI) images, and found to be consistent with a star with a bolometric magnitude -7.08+-0.36 (log L/Lsun = 4.73 +- 0.14$ dex). The magnitude of the recovered progenitor in archival images points toward a moderate-mass 10.5 (-2/+4.5) Msun star as the precursor of SN 2012A. The explosion parameters and progenitor mass were also estimated by means of a hydrodynamical model, fitting the bolometric light curve, the velocity and the temperature evolution. We found a best fit for a kinetic energy of 0.48 foe, an initial radius of 1.8X10**13 cm and ejecta mass of 12.5 Msun.

description: Steppens indflydelse på den russiske kultur
 Med særlig henblik til mongolertiden Synopsis Formålet med dette oplæg er at gennemlyse, hvordan russernes kontakter til steppefolk havde indflydelse på den russiske kultur, på samfund, og på statsvæsen. Der ligger fokus på den abstrakte spørgsmål efter modsætningen af steppen og skoven i dens kulturelle og historiske betydning og konkret på mongolertiden og dens indflydelse på Rusland, dens reception gennem tiden og den nuværende videnskabelige diskussion. English abstract This article is written in Danish language. It deals on the Russian's contacts to the peoples of the Steppe and on how these interactions had influence on Russian culture, society and political system. The main focus is on the abstract subject of the antithesis between the steppe and the woods in its cultural and historical dimension, and on the specific issue of Russia under Mongol rule, its reception history and its contemporary estimation among historians.

description: The series of calculations of differential cross sections and analyzing powers (Ay) of the elastic proton scattering on isotopes 6He and 8He was presented in the framework of the theory of Glauber multiple diffraction scattering. The three-body α-n-n and harmonic oscillator wave functions were used for 6He, for 8He - the function of density distribution in LSSM. For p6He scattering the expansion of the Glauber operator into a series of multiple scattering is written in the form consistent with the picture of weakly bound clusters in halo-nuclei, for p8He scattering the members of single- and double collisions are included in the operator. We have done the comparison of our results with available experimental data (including new data of Ay for p6He scattering at the E = 71 MeV/nucleon) and with the calculations results in the other approaches (high-energy, optical model, RMF). Also, the comparison of the characteristics of two isotopes 6He and 8He was made, which showed that they correlate quite well with each other.

description: We study a generalization of the Alessandro-Beatrice-Bertotti-Montorsi (ABBM) model of a particle in a Brownian force landscape, including retardation effects. We show that under monotonous driving the particle moves forward at all times, as it does in absence of retardation (Middleton's theorem). This remarkable property allows us to develop an analytical treatment. The model with an exponentially decaying memory kernel is realized in Barkhausen experiments with eddy-current relaxation, and has previously been shown numerically to account for the experimentally observed asymmetry of Barkhausen-pulse shapes. We elucidate another qualitatively new feature: the breakup of each avalanche of the standard ABBM model into a cluster of sub-avalanches, sharply delimited for slow relaxation under quasi-static driving. These conditions are typical for earthquake dynamics. With relaxation and aftershock clustering, the present model includes important ingredients for an effective description of earthquakes. We analyze quantitatively the limits of slow and fast relaxation for stationary driving with velocity v>0. The v-dependent power-law exponent for small velocities, and the critical driving velocity at which the particle velocity never vanishes, are modified. We also analyze non-stationary avalanches following a step in the driving magnetic field. Analytically, we obtain the mean avalanche shape at fixed size, the duration distribution of the first sub-avalanche, and the time dependence of the mean velocity. We propose to study these observables in experiments, allowing to directly measure the shape of the memory kernel, and to trace eddy current relaxation in Barkhausen noise.

description: Background Clinically, neck pain disorders (NPD) and non-specifc low back pain (NS-LBP) are respectively the fourth and frst most common conditions associated with the greatest number of years lived with disability. Remote delivery of care may beneft healthcare sustainability, reduce environmental pollution, and free up space for those requiring care non-virtual care. Methods A retrospective analysis was performed on 82 participants with NS-LBP and/or NPD who received exercise therapy delivered solely in the metaverse using virtually reality. The study was to determine if this was achievable, safe, had appropriate outcome measures that could be collected, and if there was any early evidence of benefcial efects. Results The study demonstrated that virtual reality treatment delivered via the metaverse appears to be safe (no adverse events or side efects). Data for more than 40 outcome measures were collected. Disability from NS-LBP was signifcantly reduced (Modifed Oswestry Low Back Pain Disability Index) by 17.8% (p<0.001) and from NPD (Neck Disability Index) by 23.2% (p=0.02). Conclusions The data suggest that this method of providing exercise therapy was feasible, and safe (no adverse events reported), that complete reports were obtained from a large selection of patients, and that software acquired outcomes were obtainable over a range of time points. Further prospective research is necessary to better understand our clinical fndings.

description: We study perturbative behavior of free energies on a d-dimensional sphere S^d for theories with marginal interactions. The free energies are interpreted as the "dilaton effective action" with the dilaton having a nontrivial background vacuum expectation value. We compute the dependence of the free energies on the radius of the sphere by using dimensional regularization. It is shown that the first (second) derivative of the free energies in odd (even) dimensions with respect to the radius of the sphere are proportional to the square of the beta functions of coupling constants. The result is consistent with the c, F and a-theorems in two, three, four and six dimensions. The result is also used to rule out a large class of scale invariant theories which are not conformally invariant.

description: By engineering appropriate artificial gauge potentials, a Bose-Einstein condensate can be adiabatically loaded into a current carrying state that resembles a vortex lattice of a rotating uniform Bose gas. We give two explicit, experimentally feasible protocols by which vortex lattices can be smoothly formed from a condensate initially at rest. In the first example we show how this can be achieved by adiabatically loading a uniform BEC into an optical flux lattice, formed from coherent optical coupling of internal states of the atom. In the second example we study a tight binding model that is continuously manipulated in parameter space such that it smoothly transforms into the Harper-Hofstadter model with 1/3 flux per plaquette.

description: The problem of the possible creation of mixed hadron-quark-gluon matter, that can arise at nuclear or heavy-ion collisions, is addressed. It is shown that there can exist several different kinds of such a mixed matter. The main types of this matter can be classified onto macroscopic mixture, mesoscopic mixture, and microscopic mixture. Different types of these mixtures require principally different descriptions. Before comparing theoretical results with experiments, one has to analyze thermodynamic stability of all these mixed states, classifying them onto unstable, metastable, and stable. Only the most stable mixed state should be compared with experiment. Mixed states also need to be checked with regard to stratification instability. In addition to the static stratification instability, there can happen dynamic instability occurring in a mixture of components moving with respect to each other. This effect, called counterflow instability, has also to be taken into account, since it can lead to the stratification of mixed matter.

description: La pandemia Covid-19 ha comportato conseguenze e trasformazioni prefigurando scenari inediti sul piano economico, sociale e personale, determinando anche nel campo della ricerca l’urgenza di esplorarne le ricadute. Il volume dà quindi conto delle indagini svolte e in corso, sin dai primi giorni del lockdown, dai docenti e dai collaboratori del Dipartimento di Scienze della Formazione dell’Università Roma Tre, toccando i temi più diversi: dalla didattica a distanza, all’università e nei diversi ordini di scuola, al futuro dei servizi di orientamento, dal lavoro socio-educativo nelle varie tipologie di servizi all’impatto della pandemia sulle comunità, dalle narrazioni ai linguaggi artistici a contrasto di quest’emergenza non solo sanitaria. Si sono così esplorate le diverse educazioni possibili, riassegnando centralità ai processi formativi e al benessere delle persone, provando a tratteggiare nuovi paradigmi e prospettive.
description: Questo studio indaga i benefici del contatto tra nonni e nipoti durante il periodo di lockdown dovuto alla pandemia da Covid-19. Attraverso un questionario composto da una sezione comune a tutti i rispondenti, e nove sottosezioni differenziate in base alla tipologia di rispondenti, sono stati raggiunti 303 partecipanti (101 nonni, 101 nipoti, 101 genitori) suddivisi in conviventi, non conviventi, non conviventi ma in contatto per necessità di accudimento durante il lockdown. Dai risultati è emerso che la convivenza con i nipoti è un fattore protettivo contro l’insorgenza di stati umorali negativi, senso di isolamento e solitudine nei nonni e che influenza positivamente anche il loro stato di salute. Quanto più è il tempo che nonni e nipoti trascorrono insieme, tanto più aumentano i benefici registrati in entrambe le generazioni.

description: Let $G$ be a graph on $n\geq 3$ vertices. A graph $G$ is almost distance-hereditary if each connected induced subgraph $H$ of $G$ has the property $d_{H}(x,y)\leq d_{G}(x,y)+1$ for any pair of vertices $x,y\in V(H)$. A graph $G$ is called 1-heavy (2-heavy) if at least one (two) of the end vertices of each induced subgraph of $G$ isomorphic to $K_{1,3}$ (a claw) has (have) degree at least $n/2$, and called claw-heavy if each claw of $G$ has a pair of end vertices with degree sum at least $n$. Thus every 2-heavy graph is claw-heavy. In this paper we prove the following two results: (1) Every 2-connected, claw-heavy and almost distance-hereditary graph is Hamiltonian. (2) Every 3-connected, 1-heavy and almost distance-hereditary graph is Hamiltonian. In particular, the first result improves a previous theorem of Feng and Guo. Both results are sharp in some sense.

description: A projection method is proposed to treat the one-dimensional Schrodinger equation for a single particle when the Generalized Uncertainty Principle (GUP) generates an ultraviolet (UV) wavevector cutoff. The existence of a unique coordinate representation called the naive one is derived from the one-parameter family of discrete coordinate representations. In this bandlimited Quantum Mechanics a continuous potential is reconstructed from discrete sampled values observed by means of a particle in maximally localized states. It is shown that bandlimitation modifies the speed of the center and the spreading time of a Gaussian wavepacket moving in free space. Indication is found that GUP accompanied by bandlimitation may cause departures of the low-lying energy levels of a particle in a box from those in ordinary Quantum Mechanics much less suppressed than commonly thought when GUP without bandlimitation is in work.

description: Among all entanglement measures negativity arguably is the best known and most popular tool to quantify bipartite quantum correlations. It is easily computed for arbitrary states of a composite system and can therefore be applied to discuss entanglement in an ample variety of situations. However, its direct physical meaning has not been pointed out yet. We show that the negativity can be viewed as an estimator of how many degrees of freedom of two subsystems are entangled. As it is possible to give lower bounds for the negativity even in a device-independent setting, it is the appropriate quantity to certify quantumness of both parties in a bipartite system and to determine the minimum number of dimensions that contribute to the quantum correlations.

The quantum nature and the separability of NC two-mode Gaussian states are examined. It is shown that the entanglement of Gaussian states may be exclusively induced by switching on the noncommutative deformation.

description: We study N=2 vacua in spontaneously broken N=4 electrically gauged supergravities in four space-time dimensions. We argue that the classification of all such solutions amounts to solving a system of purely algebraic equations. We then explicitly construct a special class of consistent N=2 solutions and study their properties. In particular we find that the spectrum assembles in N=2 massless or BPS supermultiplets. We show that (modulo U(1) factors) arbitrary unbroken gauge groups can be realized provided that the number of N=4 vector multiplets is large enough. Below the scale of partial supersymmetry breaking we calculate the relevant terms of the low-energy effective action and argue that the special Kahler manifold for vector multiplets is completely determined, up to its dimension, and lies in the unique series of special Kahler product manifolds.

description: In an earlier paper we demonstrated that the "novel attractive force" between protons in dense hydrogen reported by Shukla and Eliasson based on linearized quantum hydrodynamics (LQHD) is wrong. As benchmark results we used state of the art density functional theory (DFT) simulations. In their response to that paper Shukla et al. (arXiv:1112.5556) claimed that the disagreement is due to a failure of DFT. Here we show - by comparing the properties and limitations of DFT and QHD - that their statements have no scientific basis and that DFT is a suitable benchmark for more approximate approaches such as QHD and LQHD.

Subjects: Russian, verbs of motion, translation, corpus linguistics

description: This study will examine the prefixed derivates from the verb of motion (VoM) ходить and analyse their translations to German by focusing on the problem of determining the correct meaning of individual forms and possible irregularities in the translation. The study shows that prefixed verbs that are otherwise identical can be homonyms with meanings that are independent from each other. This is because of the different grammatical and lexical processes that have accordingly led to an ambiguous form. The goal of this thesis is to begin by illustrating the problem of homonymy of forms caused by aspect and aktionsart. After having done so, the issue will be considered in light of the problems that can arise in the comprehension and translation of homonymous forms by analysing actual text material from Russian text corpora. I will endeavour to locate regularities in their translation and thereby examine the demands on theory and corpora. The analysis will also investigate how effectively the theoretical background of Isačenko’s theory on aspect and aktionsart can be applied to corpus linguistics.

description: We propose a new type of surfactants, namely, tetrazole derivatives which can be controllably removed from the nanoparticle surface. Tetrazoles are a peculiar class of heterocyclic compounds. The presence of four nitrogen atoms in the tetrazole ring determines their interesting physical and chemical properties. Tetrazoles show high thermal stability below 200C while decomposing at higher temperature with formation of gaseous products and no or very little solid residue. Moreover, the tetrazole group is known as an important ligand in coordination chemistry. Its donor nitrogen atoms can bind to various metal ions leading to stable complexes with diverse coordination modes of the heteroring. We report the synthesis of CdS NPs capped with 1-R-5-thiotetrazoles using two different synthetic schemes: solution-phase and solventless single precursor approaches. In both synthetic procedures cadmium thiotetrazolates were used as cadmium precursors and sources of surfactant.

description: In this paper we provide the reader with a visual representation of relationships among the impact of book chapters indexed in the Book Citation Index using information gain values and published by different academic publishers in specific disciplines. The impact of book chapters can be characterized statistically by citations histograms. For instance, we can compute the probability of occurrence of book chapters with a number of citations in different intervals for each academic publisher. We predict the similarity between two citation histograms based on the amount of relative information between such characterizations. We observe that the citation patterns of book chapters follow a Lotkaian distribution. This paper describes the structure of the Book Citation Index using 'heliocentric clockwise maps' which allow the reader not only to determine the grade of similarity of a given academic publisher indexed in the Book Citation Index with a specific discipline according to their citation distribution, but also to easily observe the general structure of a discipline, identifying the publishers with higher impact and output.

description: I denne opgave vil jeg kontrastivt redegøre for hvordan anglicismer indgår i russisk og i tysk på form- og betydningsmæssig plan dvs. hvilke forskelle og ligheder der kan konstateres ved lån fra det engelske kildesprog mellem de to målsprog. Der koncentreres udelukkende på sprogfænomener som er relevante for skriftsproget, dvs. at jeg vil behandle spørgsmål omkring anglicismernes udtale i de to målsprog kun, hvor disse berører ortografien eller orddannelsen. Først vil jeg koncentrere mig om anglicismer i deres sproghistorisk aspekt, på hvornår, hvordan og på hvilken omfang engelsk påvirkede tysk og russisk i løbet af tiden for at prøve at vise grundene til denne indflydelse. Derefter vil jeg redegøre for regelmæssigheder og problemer vedrørende låneordenes formal integration til målsprogenes morfologiske og syntaktiske system, og fremstille semantikkens rolle i låneprocessen.

description: Global Early Childhood Development (ECD)—an applied field with the aim to improve the “brain structure and function” of future generations in the global South—has moved to the center of international development. Global ECD rests heavily on evidence claims about widespread cognitive, social, and emotional deficits in the global South and the benefits of changing parenting practices in order to optimize early childhood development. We challenge these claims on the grounds that the leading ECD literature excludes research from anthropology, cultural psychology, and related fields that could provide crucial insights about childrearing and children's development in the targeted communities. We encourage anthropologists and other scholars with ethnographic expertise on childhood to critically engage with global ECD. To facilitate such an endeavor, this article sketches the history, scientific claims, and interventions of global ECD, points out the critical potential of ethnographic research, and suggests strategies to make ethnography more relevant.
The effect of bound states on X-ray Thomson scattering for partially ionized plasmas

description: X-ray Thomson scattering is being developed as a method to measure the temperature, electron density, and ionization state of high energy density plasmas such as those used in inertial confinement fusion. X-ray laser sources have always been of interest because of the need to have a bright monochromatic x-ray source to overcome plasma emission and eliminate other lines in the background that complicate the analysis. With the advent of the xray free electron laser (X-FEL) at the SLAC Linac Coherent Light Source (LCLS) and other facilities coming online worldwide, we now have such a source available in the keV regime. Most Thomson scattering codes used to model experimental data greatly simplify or neglect the contributions of the bound electrons to the scattered intensity. In this work we take the existing models of Thomson scattering that include elastic ion-ion scattering and inelastic electron-electron scattering and add the contribution of bound electrons in the partially ionized plasmas. To date, most experiments have studied hydrogen or beryllium plasmas. We first analyze existing experimental data for beryllium to validate the code. We then consider several higher Z materials such as Cr and predict the existence of additional peaks in the scattering spectrum that requires new computational tools to understand. For a Sn plasma, we show that bound contributions change the shape of the scattered spectrum in a way that would change the plasma temperature and density inferred from experiment.

description: We present the analysis of Spitzer/IRAC and NIR imaging observation of AFGL 5157, an active star forming region. In the IRAC images, this region shows strong PAH emissions in channel 4 and H$_2$ emissions in channel 2. Many of the H$_2$ features are aligned to form jet-like structures. Three bipolar jets in the NH$_3$ core region and a couple of jets northwest of the core have been identified. We identify the possible driving agents of the bipolar jets and show them to be very young. An embedded cluster has been detected in the NH$_3$ core; many members in the cluster show their SEDs increasing from JHK bands toward longer wavelength, indicative of their early evolutionary stages. Millimeter and sub-millimeter continuum emissions are found to coincide spatially with these presumable Class 0/I sources, in the NH$_3$ core and the NW subregion. The existence of H$_2$ bipolar jets and very young stellar objects suggests that star formation is still going on at present epoch in these subregions. Combining the information from previous studies, we propose a sequential star formation scenario in the whole AFGL 5157 region.

description: Nitrogen (N) availability has been considered as a critical factor for the cycling and storage of soil organic carbon (SOC), but effects of N enrichment on the SOC pool appear highly variable. Given the complex nature of the SOC pool, recent frameworks suggest that separating this pool into different functional components, for example, particulate organic carbon (POC) and mineral-associated organic carbon (MAOC), is of great importance for understanding and predicting SOC dynamics. Importantly, little is known about how these N-induced changes in SOC components (e.g., changes in the ratios among these fractions) would affect the functionality of the SOC pool, given the differences in nutrient density, resistance to disturbance, and turnover time between POC and MAOC pool. Here, we conducted a global meta-analysis of 803 paired observations from 98 published studies to assess the effect of N addition on these SOC components, and the ratios among these fractions. We found that N addition, on average, significantly increased POC and MAOC pools by 16.4% and 3.7%, respectively. In contrast, both the ratios of MAOC to SOC and MAOC to POC were remarkably decreased by N enrichment (4.1% and 10.1%, respectively). Increases in the POC pool were positively correlated with changes in aboveground plant biomass and with hydrolytic enzymes. However, the positive responses of MAOC to N enrichment were correlated with increases in microbial biomass. Our results suggest that although reactive N deposition could facilitate soil C sequestration to some extent, it might decrease the nutrient density, turnover time, and resistance to disturbance of the SOC pool. Our study provides mechanistic insights into the effects of N enrichment on the SOC pool and its functionality at global scale, which is pivotal for understanding soil C dynamics especially in future scenarios with more frequent and severe perturbations.
Pseudo magnetic field in strained graphene: revisited

description: We revisit the theory of the pseudo magnetic field as induced by strain in graphene using the tight-binding approach. A systematic expansion of the hopping parameter and the deformation of the lattice vectors is presented from which we obtain an expression for the pseudo magnetic field for low energy electrons. We generalize and discuss previous results and propose a novel effective Hamiltonian. The contributions of the different terms to the pseudo magnetic field expression is investigated for a model triaxial strain profile and are compared with the full solution. Our work suggests that the previous proposed pseudo magnetic field expression is valid up to reasonably high strain 15 % and there is no K-dependent pseudo-magnetic field.

description: В практике торакальной хирургии мы заметили, что при наличии процессов атеросклероза в стенках большого круга совершенно отсутствуют изменения в стенках сосудов малого круга, т. е. последние остаются совершенно интактными. Целью исследования являлся поиск корреляции между повышенным давлением и процессом атеросклероза в большом и малом круге кровообращения. Был проведен анализ 72 протоколов патологоанатомических вскрытий, на предмет наличия атеросклероза и анамнестического наличия повышения артериального давления. В результате у группы пациентов с атеросклерозом сосудов большого круга кровообращения в анамнезе регистрировалась длительно протекающая гипертоническая болезнь. У пациентов с атеросклерозом большого и малого круга кровообращения – гипертоническая болезнь сочеталась с хронической обструктивной болезнью легких или признаками вторичной легочной гипертензии. У пациентов с атеросклерозом только малого круга – в анамнезе регистрировалась легочная гипертензия второй степени. И такие пациенты были сравнительно молодого возраста, что говорит о том, что гипертоническая болезнь еще не успела развиться. Таким образом, существует корреляционная взаимосвязь между повышенным артериальным давлением и процессами атеросклероза. Стоит отметить, что данная работа является оригинальной, и
подобного сравнения в литературных источниках не было отмечено.
Tangible pasts: Memory practices among children and adolescents in Germany, an affect-theoretical approach

description: This article highlights the ontogeny of autobiographical memory and its sociocultural foundations as an important and underrepresented field of research in psychological anthropology. It discusses the results of an explorative photovoice study on the emotional experiences of children and adolescents. Our study discovered that memory practices play a major role in young people's daily lives. Participants often referred to emotionally significant past events, relationships, or life periods by relating them to particular memory objects. We assume that the material dimension of children's memory practices not only facilitates an affective engagement with the past but also makes past experiences communicable to oneself and to others. The memory objects used by our research participants were linked in substantial ways to culturally specific modes of remembering, (auto)biographical narration, and the formation of feeling among adolescents. In discussing broader implications of our results, we draw on insights from developmental psychology, affect and emotion theory, and social anthropological research on memory and materiality. We conclude with a brief comparative look at memory practices in the Indonesian context to hint at a significant field of cross-cultural research that opens at the intersection of studies on material culture, memory practices, (auto)biographical remembering and narrating, and the formation of feeling.
