description: I propose to formalize quantum theories as topological quantum field theories in a generalized sense, associating state spaces with boundaries of arbitrary (and possibly finite) regions of space-time. I further propose to obtain such ``general boundary'' quantum theories through a generalized path integral quantization. I show how both, non-relativistic quantum mechanics and quantum field theory can be given a ``general boundary'' formulation. Surprisingly, even in the non-relativistic case, features normally associated with quantum field theory emerge from consistency conditions. This includes states with arbitrary particle number and pair creation. I also note how three dimensional quantum gravity is an example for a realization of both proposals and suggest to apply them to four dimensional quantum gravity.

description: We show how the viscous evolution of Keplerian accretion discs can be understood in terms of simple kinetic theory. Although standard physics texts give a simple derivation of momentum transfer in a linear shear flow using kinetic theory, many authors, as detailed by Hayashi & Matsuda 2001, have had difficulties applying the same considerations to a circular shear flow. We show here how this may be done, and note that the essential ingredients are to take proper account of, first, isotropy locally in the frame of the fluid and, second, the geometry of the mean flow.

description: Excerpts from the report Preface: Snap beans are one of our more important vegetable crops, with an average annual production of nearly 20,000,000 bushels and with an annual farm value of over $40,000,000. "Russeting" is frequently a serious problem with snap beans, and special attention has been given to determining its nature and methods of control, as even slight russeting affects the market value of beans, and severe russeting sometimes makes them worthless. Figures for summer squash production and value are not available, but these squashes are a fairly important fresh vegetable item in retail stores. Previous studies have shown that summer squashes are very perishable, remaining in good condition on a nonrefrigerated dry display rack for only 1 day. This study of deterioration of the two vegetables and of ways of minimizing it is part of a national program of research to improve the marketing of farm products.

description: The known facts about solvability of equations over groups are considered from a more general point of view. A generalized version of the theorem about solvability of unimodular equations over torsion-free groups is proved. In a special case, this generalized version become a multivariable variant of this theorem. For unimodular equations over torsion free groups, we prove an analogue of Magnus's Freiheitssatz, which asserts that there exists a solution with good behavior with respect to free factors of the initial group.

description: Terrestrial laser scanning provides highly accurate and dense 3D measurements of an object. This technology leads to several applications, for example in topographic surveys, forestry, and as-built documentation. Few developments exist in the area of agriculture and precision farming. In this contribution, multi-temporal 3D terrestrial laser scanning was applied for field crop modelling. The time-of-flight laser scanner Riegl LMS-Z420i was used three to five times per year to estimate plant height distribution of the field crops winter wheat, spring barley, and sugar beet. In 2008 and 2009, the area under investigation was a single field. As a further development, data from plots with different crop varieties of barley and sugar beet were analysed in 2010. As a result, within-field variability was detected by using crop surface models (CSM) and crop volume models (CVM). Single plants were successfully detected. The results will be compared with additional data in the future.

subject: structural adjustment

description: The purpose of this study is identifying the sources of declining in chemical fertilizer consumption in Korea. Furthermore, this study aims at providing forecasts of fertilizer demands incorporating the impacts of those sources. The study estimates a demand function of fertilizer, and investigates the impacts of reducing fertilizer subsidy on fertilizer demand. The impacts of the policy change on farming cost are estimated by an input-output analysis. The results are combined with those of a time-series estimation of per acre fertilizer consumption and total acreage in order to derive a complete forecast of fertilizer demand in 2013. The paper shows that fertilizer consumption will decline substantially in 10 years, and fertilizers will be over-supplied unless an effective structural adjustment is performed by the industry.
Fate of Fermi-arc States in Gapped Weyl Semimetals under Long-ranged Interactions

description: For noninteracting Weyl semimetals (WSMs), Fermi-arc surface states can arise when there exist gapless Weyl nodes in the bulk single-particle spectrum. However, in the presence of electronic correlations, it is not clear whether this bulk-boundary correspondence still holds or not. Recently, novel correlated phases are predicted to appear in WSMs with long-ranged interactions, in which the bulk Weyl nodes can be gapped but without destroying their topological properties. Here, we explore the fate of the Fermi-arc states under the influence of such long-ranged interactions. After mapping the system onto a one-dimensional interacting Su-Schrieffer-Heeger (SSH) model with two open ends, we employ numerical exact diagonalizations to address the issue whether the Fermi-arc states will be modified. By extrapolating our data to the thermodynamic limit, we find that the zero-energy edge states of the corresponding SSH model still exist for those momenta giving the noninteracting Fermi-arc states. Moreover, this observation applies to both the single-particle and the collective edge excitations. Since the locus of these edge states constitutes the Fermi arcs, the robustness of the Fermi-arc states against long-ranged interactions is thus demonstrated. In particular, the Fermi arcs of single-particle nature can survive even when the single-particle gaps at the Weyl nodes are opened by interactions. Our results illustrate the subtlety in identifying the topological phases of interacting WSMs and show the limitation of the approaches simply by examining the nodal structure of the single-particle spectrum.

description: Στη σύγχρονη εποχή, η ασθένεια του καρκίνου αποτελεί μία από τις πιο κοινές αιτίες θανάτου παγκοσμίως. Παρόλο που έχει αναπτυχθεί ένα πλήθος θεραπευτικών μεθόδων για την αντιμετώπισή του, οι παρενέργειες που προκαλούνται αποτελούν περιοριστικό παράγοντα για την εφαρμογή τους, καθώς η διάκριση μεταξύ των καρκινικών και υγιών κυττάρων είναι μικρή. Έτσι, η ανακάλυψη νέων στόχων και πιο εκλεκτικών αντικαρκινικών μέσων θα μπορούσε να επιφέρει αύξηση των επιτυχημένων θεραπειών και μείωση των παρενεργειών. Έναν τέτοιο πιθανό στόχο αποτελούν και οι πρωτεΐνες STAT. Ο περιορισμός της δράσης τους έχει βρεθεί ότι παρουσιάζει μείωση της ανάπτυξης κάποιων ειδών καρκινικών όγκων. Η αναστολή τους μπορεί να επιτευχθεί τόσο με συνθετικά μόρια όσο και με ένα πλήθος φυσικών προϊόντων. Παράδειγμα ενός τέτοιου φυσικού προϊόντος αποτελούν οι ενώσεις της οικογένειας των Φαιοσφαιριδίων. Μελέτες έχουν δείξει ότι αυτές οι ενώσεις παρουσιάζουν αυξημένη ανασταλτική δράση των πρωτεϊνών STAT σε διάφορους τύπους καρκίνου όπως η λευχαιμία. Στην παρούσα διπλωματική εργασία, παρουσιάζεται η σύνθεση και ο χαρακτηρισμός της δομής μιας σειράς αναλόγων της προτεινόμενης δομής του Φαιοσφαιριδίου Α.

Τέλος, αναμένονται τα αποτελέσματα των βιολογικών δοκιμών αυτών των ενώσεων.
description: Nowadays, cancer is one of the most common causes of death worldwide. Although a number of methods has been developed for the treatment of cancer, the side effects limit their application, as there are small differences between cancer and healthy cells. Thus, the discovery of new targets and more selective anticancer agents could increase the number of successful treatments and reduce the side effects. One such possible target could be STAT proteins. The inhibition of their activity has found to reduce the growth of some cancer types. The inhibition can be achieved with both synthetic compounds and some natural products. A representative example is the natural product Phaeosphaeride A. Studies have shown that phaeospaerides show increased inhibition of STAT proteins in many cancer types like leukemia. In this work, the synthesis and the characterization of analogues of the proposed structure of Phaeosphaeride A are presented. These derivatives have some structural changes in the five-membered ring of the natural product. These changes have been achieved through a vinylogous aldol reaction in which 4-methoxyfuran-2(5H)-one and its derivatives have been used. Finally, the results of biological assays of these compounds are expected.

Abstract  Trastuzumab deruxtecan (ENHERTU®), a HER2-directed antibody and DNA topoisomerase I inhibitor conjugate, is being developed for the treatment of HER2-expressing solid tumours, including breast cancer, gastric cancer, colorectal cancer and non-small cell lung cancer by Daiichi Sankyo Company Ltd in collaboration with AstraZeneca. Based primarily on the results of the phase 2 DESTINY-Breast01 trial, trastuzumab deruxtecan was recently approved in the USA under accelerated approval for the treatment of adult patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting. This article summarizes the milestones in the development of trastuzumab deruxtecan leading to this first approval.

description: Σκοπός αυτής της μελέτης είναι να εξετάσει τον τρόπο με τον οποίο το κακό εμφανίζεται στους μύθους. Ως εκ τούτου εκκινεί από μία ιστορική ανασυγκρότηση των θεωριών που αφορούν αυτό που στη φιλοσοφία ονομάζεται πρόβλημα του κακού και έπειτα προχωρά στη διασάφηση του όρου «μύθος». Στη συνέχεια επιχειρείται η αναζήτηση θέσεων για την καταγωγή του κακού οι οποίες εντοπίζονται σε σημαντικούς μύθους. Σε αυτό το πλαίσιο γίνεται μία εκτενής ανάγνωση και ερμηνευτική ανάλυση του προπατορικού αμαρτήματος. Μέσω αυτής αναφέρονται και σχολιάζονται τα σύμβολα, οι έννοιες του καλόυ, του κακού, της ηθικής ευθύνης, της τιμωρίας, της πτώσης κ.ά. Συγκριτικά προς αυτόν τον μύθο διαβάζονται και αναλύονται αποσπάσματα από μύθους του Ησιόδου και από τα προερχόμενα από την ανατολή Ενούμα Έλις και Έπος του Γιλγαμές. Τελικώς, ελέγχεται ο τρόπος με τον οποίο προσλήφθηκε ο μύθος του προπατορικού αμαρτήματος -η ανάλυση του οποίου βρίσκεται στον πυρήνα της εργασίας- σε διάφορους τομείς, όπως για παράδειγμα στη λογοτεχνία, τις απεικονιστικές τέχνες, την εκπαίδευση και τη φιλοσοφία.
description: The purpose of this study is to examine how evil appears in myths. Therefore, the study starts from a historical reconstruction of theories concerning the problem of evil and then proceeds to the definition of the term "myth". This is followed by a search for views regarding the origin of evil which are found in important myths. In this context, an extensive reading and interpretative analysis of original sin is made. Through this examination, the symbols, the concepts of good, evil, moral responsibility, punishment, fall, etc. are mentioned and commented. In comparison to this myth, excerpts from the myths of Hesiod, the oriental Enuma Ellis and the Epic of Gilgamesh are read and analyzed. Finally, the way in which the myth of original sin is examined was received - the analysis of which lies at the core of the work - in various fields, such as literature, visual arts, education and philosophy.

description: Transitioning into fatherhood can cause mental health issues such as post-partum depression (PPD). Paternal PPD not only affects the individual, but their relationships with partners and children as well. This scoping review explores paternal PPD, the experience of new fathers during the post-natal period, fathers’ knowledge gaps and learning preferences; post-natal and men’s health programs are also identified. Findings drawn from this review inform recommendations for postnatal programs to improve the inclusion of new fathers amid describing how NPs can promote men’s health in the postpartum period. To complete the requirements of the culminating project, this scoping review has been developed into a manuscript for submission for publication.

description: Tariff structure of Korean forestry sector can be characterized by relatively simple structure with higher applied rates than in Japan. Although, tariff items are well-classified in detail, neither tariff dispersion nor tariff escalation can be found. On the contrary, Japanese tariff structure is complicate with various tariff headings and categories for forestry commodities. Korea has relatively higher market comparative advantages for chest nut, fiber board, wood cases and pine mushroom while Japan has that in coniferous plywood and wood cases. Considering market comparative advantages and higher applied tariff rates for most forestry products, imports from Japan may surge more rapidly than export to Japan from Korea as a result of trade liberalization.

The imperative of today is using of Internet in all areas of society. Some researchers believe that e-learning is a combination of quality and progressive educational achievements of technology. It is based on the principles of free learning, using computers in the educational programs and modern telecommunications. New Internet technologies enable using of various records that are combined in the multimedia content and present students. This paper provides a description of the development of technologies that accompanied this form of learning. The objective of the paper is to introduce the most important concepts of distance learning through new technologies to wider auditoriums.

description: Fe-gluconate, Fe(C_6H_11O_7_2xH_2O is a well-known material widely used for iron supplementation. On the other hand, it is used in food industry as a coloring agent, in cosmetic industry for skin and nail conditioning and metallurgy. Despite of wide range of applications its physical properties were not studied extensively. In this study, Fe-gluconate with three different amount of water viz. x=2 (fully hydrated, 0 < x < 2 (intermediate) and x=0 (dry) was investigated by means of X-ray diffraction (XRD) and Mössbauer spectroscopic (MS) methods. The former in the temperature range of 20-300 K, and the latter at 295 K. Based on the XRD measurements crystallographic structures were determined: monoclinic (space group I2) for the hydrated sample and triclinic (space group P1) for the dry sample. The partially hydrated sample was two-phased. Unit cells parameters for both structures show strong, very complex and non-monotonic temperature dependences. Mössbauer spectroscopic measurements gave evidence that iron in all samples exist in form of Fe(II) and Fe(III) ions. The amount of the latter equals to ca.30% in the hydrated sample and to ca.20% in the dry one.

Therefore, it is necessary to study the basic performance of the domestic capital market, because it is a necessary condition for further development and a positive direction. Special attention is paid to the Belgrade Stock Exchange as a secondary capital market and the basic infrastructure of trading securities. Also, the question of used and missed opportunities arises, from establishing of a market economy, after the collapse of the socialist block, through the global financial crisis to date. The answer to this question is also a way to improvement and development of domestic capital market.

Four experimental groups were studied: a) rats reared normally from birth until 52 days post natum (DPN) - Group 52dL, b) rats reared upto 21 DPN in darkness and subsequently light exposed for 31 days - Group 21/31, c) rats dark-reared until 52 DPN and light exposed for 3 days - Group 3dL, and d) rats totally dark-reared until 52 DPN - Group 52dD. The principal morphological correlates of dark-rearing and light exposure were: i) a significant reduction in the volume numerical density (N^) of astroglia and oligodendroglia in lower layer V of the visual cortex in groups 3dL and 52dD "additionally, group 3dL showed a dramatic increase in microglia N^ in thalamorecipient layer IV. No differences were detected in neuronal N^ between groups, and few morphological differences were found between groups 52dL and 21/31. The neuron and glia cell populations in the dLGN were relatively unaffected by dark-rearing. ii) Although the number, spacing and cross-sectional area of dendritic bundles in layer IV of the visual cortex were similar between the experimental groups, the number of dendritic profiles and their areal density per cluster were significantly reduced in groups 3dL and 52dD compared to group 21/31. iii) The major ultrastructural differences concern marked deficits in the 'inhibitory' circuitry of layer IV of the visual cortex, and in the synaptic glomeruli of the dlGN in group 52dD compared to group 21/31. These results are considered in relation to previous studies investigating the morphological effects of visual deprivation on the mammalian visual system. Part two is an immunocytochemical study identifying the GABAergic elements of the rat cerebellum using a serum against the 'inhibitory' neurotransmitter GABA. The somata and processes of Golgi, basket, and stellate cells were invariably immunopositive, as were the axon terminals of Purkinje cells. Granule cells, parallel fibres, mossy and climbing fibres, and neuroglia were immunonegative. Subsequently, the anti-GABA serum was used to identify the GABA-ergic nature of neurons in the rat dLGN using a combined immunocytochemical and Golgi/EM approach. The results of this study indicate that the thalamocortical projection cells are GABA immunonegative whilst the 'interneurons' are GABA immunopositive. Finally, a method is described which allows the Golgi-impregnation of a 'single' histological section 60-200pm thick.

description: We present here a multilayer model for shallow grain-fluid mixtures with dilatancy effects. It can be seen as a generalization of the depth-averaged model presented in Bouchut et al. (2016), that includes dilatancy effects by considering a two-layer model, a mixture grain-fluid layer and an upper fluid layer, to allow the exchange of fluid between them. In the present work the approximation of the mixture layer is improved including normal variations of the velocities and concentrations of the two phases thanks to the multilayer approach. In the model presented here dilatancy effects induce in particular a non-hydrostatic pressure for both phases related to the excess pore fluid pressure. We identified here one of the main numerical difficulty of solving two-phase shallow debris flows models: the strongly non-linear behaviour and abrupt changes of the excess pore fluid pressure when starting from non-equilibrium conditions. We propose a simplified approach to approximate the excess pore fluid pressure in the simple case of uniform flows. Our method makes it possible to introduce two or three layers in the normal directions with a reasonable approximation. Analytical solutions for uniform grain-fluid flows over inclined planes, with and without side wall friction, are calculated and compared to the proposed model. In the numerical results, we observe that the proposed model with a two layer description of the mixture accurately represents the velocity measured at the surface of the mixture in the laboratory experiments. This is obviously poorly represented by the depth-averaged velocity in single-layer models. Our numerical results show a significant impact of the parameters involved in dilatancy law, in particular on the calculation of the time evolution of the excess pore fluid pressure.
title: Prices and Wages in Stafford 1780-1850: An Investigation of Local Sources.
Creators: name: Kirby, David Geoffrey
Publisher: name: The Open University
Year: 1984

description: The thesis maintains that local research has a vital part to play in the debate about living standards. Local experience differed from that indicated in national aggregated statistics, and local records will permit a greater insight into the experiences of individuals. At the moment the amount of local information which has been researched is too limited to influence the overall direction of the debate. The thesis is an investigation of sources which might add to local knowledge of prices and earnings. Chapters 1 and 2 review the context of the research. Chapter 1 summarises the state of the debate, drawing particular attention to T. S. Ashton's requirement of a variety of indexes to measure local and temporary changes in prices and earnings. Chapter 2 explains the status of Stafford itself. The Stafford Record Office has a variety of sources which enable Ashton's requirements to be met. Local newspapers, hospital and workhouse records have daily and weekly reference to a wide range of foods and other domestic commodities. Chapters 3, 4, 3, 6 and 7 demonstrate the possibility of creating prices indexes for comparison with other data. Local estate records reveal detailed information of the work and earnings of individual farm workers. Chapters 8, 9, 10 and 11 analyse the work as well as the wage rates and the earnings of individual men and women. It seems that farm workers near Stafford might have suffered frequent, rapid and unpredictable changes in their standard of living; that fluctuations in income might well have been weekly; and that women's earnings were an essential element in the family income. From the sources in the Stafford Record Office it will be possible to make a valuable contribution to the standard of living debate.

description: In this paper, we describe a way to construct a class of dark energy models that admit late time de Sitter attractor solution. In the canonical scalar and Born-Infeld scalar dark energy models, we show mathematically that a simple sufficient condition for the existence of a late time de Sitter like attractor solution is that the potentials of the scalar field have non-vanishing minimum while this condition becomes that the potentials have non-vanishing maximum for the phantom models. These attractor solutions correspond to an equation of state $w=-1$ and a cosmic density parameter $Ω_ϕ=1$, which are important features for a dark energy model that can meet the current observations.

description: Ο ιαματικός τουρισμός (ή θερμαλισμός) αποτελεί μία από τις πιο γνωστές και ίσως την αρχαιότερη μορφή τουρισμού και αποτελεί κομμάτι ενός πολύ ανερχόμενου είδους εναλλακτικού τουρισμού, του τουρισμού υγείας. Από την άλλη πλευρά, η καινοτομία είναι ένα από τα πιο πολυσυζητημένα ζητήματα του οικονομικού, και όχι μόνο, κλάδου. Πρόκειται για ένα θέμα το οποίο μελετάται κυρίως στο βιομηχανικό τομέα. Η έρευνα σχετικά με την καινοτομία στον ιαματικό τουρισμό, αλλά και τον τουρισμό γενικά, είναι ακόμα σε πρωταρχικό στάδιο και σχετίζεται περισσότερο στην απλή περιγραφή της κατάστασης. Σκοπός της εργασίας έρευνας είναι η διερεύνηση των καινοτομιών για την ανάπτυξη του ιαματικού τουρισμού. Πιο συγκεκριμένα οι αντικειμενικοί στόχοι της εργασίας είναι η χαρτογράφηση των επιχειρήσεων ιαματικού τουρισμού στον ελλαδικό χώρο, η αναζήτηση των καινοτόμων δράσεων των επιχειρήσεων ιαματικού τουρισμού, η διερεύνηση των ωφελειών των καινοτομιών που εφαρμόζονται στις επιχειρήσεις ιαματικού τουρισμού και η ανάδειξη των κατάλληλων δεικτών μέσω των οποίων μπορούμε να μετρήσουμε την καινοτομία και τις ωφέλειές της στο επίπεδο των επιχειρήσεων του ιαματικού τουρισμού. Η έρευνα πραγματοποιήθηκε μέσω ερωτηματολογίων που απαντήθηκαν από επιχειρήσεις που δραστηριοποιούνται στον κλάδο του θερμαλισμού και από ειδήμονες στο χώρο της καινοτομίας. Στην έρευνα συμμετείχαν είκοσι πέντε επιχειρήσεις και οχτώ ειδήμονες.
description: Spa tourism (or thermalism) is one of the most famous and perhaps the oldest form of tourism and is part of a very emerging type of alternative tourism, health tourism. On the other hand, innovation is one of the most talked about issues in the economic, and not only, industry. This is an issue that is being studied mainly in the industrial sector. Research on innovation in spa tourism, but also tourism in general, is still in its infancy and is more related to the simple description of the situation. The purpose of the research work is to explore innovations for the development of spa tourism. More specifically, the objective objectives of the work are the mapping of spa tourism companies in Greece, the search for innovative actions of spa tourism companies, the exploration of the benefits of innovations applied in spa tourism companies and the promotion of appropriate indicators through which we can measure innovation and its benefits at the level of spa tourism businesses. The research was conducted through questionnaires answered by companies active in the thermal industry and by experts in the field of innovation. Twenty-five companies and eight experts participated in the research.

description: There are several applications and fundamental research areas which require the detection of VUV light at cryogenic temperatures. For these applications we have developed and successfully tested special designs of gaseous detectors with solid photocathodes able to operate at low temperatures: sealed gaseous detectors with MgF2 windows and windowless detectors. We have experimentally demonstrated, that both primary and secondary (due to the avalanche multiplication inside liquids) scintillation lights could be recorded by photosensitive gaseous detectors. The results of this work may allow one to significantly improve the operation of some noble liquid gas TPCs.

description: The charge inversion phenomenon is studied by molecular dynamics simulations, focusing on size and valence asymmetric salts, and a threshold of surface charge density for charge inversion. The charge inversion criteria by the electrophoretic mobility and the radial distribution functions of ions coincide except around the charge inversion threshold. The reversed electrophoretic mobility increases with the ratio of coion to counterion radii, while it decreases with the ratio of coion to counterion valences. The monovalent salt enhances charge inversion of a strongly charged macroion at small ionic strength, but it reduces reversed mobility otherwise. A cylindrical macroion is more persistent to monovalent salt than a spherical macroion of the same radius and surface charge density.

description: During the determination of the case and target goals versus scientific research, it is necessary to satisfy the principle of complete, exact and timely reporting of balance. Previously mentioned, in view of any and every business entity, is the reason for the perception versus the realistic presentation of the financial situation and business entities. Because, permanent, present evaluation of the financial position, and under inluencijom numerous and heterogeneous internal and external factors, there is a need for propulsive and complex analysis of the current situation, trends and ex ante perspective, looking at growth and development of business entities.
