title: The interaction between hydrogenase activity and carbon metabolism in nitrogen-fixing legume root nodules
Creators: name: Borthakur, Pritty B
Publisher: name: The Open University
Year: 1986

description: Rhizobium and Bradyrhizobium species fix atmos¬pheric nitrogen (N2) in symbiotic association with legumes. The endosymbiotic bacteroid-forms contain the nitrogenase enzyme complex which catalyzes the reduction of Ng to produce ammonia (NH3) using energy derived from the respiration of photosynthate supplied by the host plant. Hydrogen is also evolved as a by-product of the nitrogenase reaction and at least 25% of the energy is wasted through H2 evolution. However, some strains of rhizobia possess a hydrogen oxidising enzyme called ’uptake hydrogenase’ (Hup), that can recycle the H2 evolved as a by-product of N2 fixation and regenerate energy in the form of ATP. This dissertation considers three topics relating to the physiology of symbiotic N2 fixation (i) what is the energy cost of symbiotic N2 fixation for the whole plant, and how significant are the losses associated with H2 evolution ? (ii) what factors limit the rate and efficiency of symbiotic N2 fixation ? (iii) Does the hydrogen recycling (uptake hydrogenase) system confer any advantages to the bioenergetics of symbiotic N2 fixation ? The scientific literature in each of these areas is reviewed, and some suggestions made concerning future experiments which might help to investigate the contribution of the uptake hydrogenase system to the energetics of symbiotic N2 fixation. Rhizobia are obligate aerobes but the nitrogenase system is very sensitive to oxygen damage. Consequ¬ently, the root nodule is maintained as a microaerobic environment for the N2 fixing bacteroids. The O2 supply to the centre of nodules appears to be tightly regulated and in some cases the availability of O2 may limit the rate of respiration and hence the energy available for N2 fixation. In addition, the carbon supply to bacteroids is a major factor limiting the activity of root nodules. Environmental factors suchas fixed nitrogen in the soil, other mineral nutrients, temperature and moisture, etc, also affect nodulation and N2 fixation by rhizobia. Experiments conducted with Hup+ and Hup- isogenic strains show that the Hup system is beneficial in the soybean-Bradyrhizobium symbiosis. In the pea-Rhizobium symbiosis the beneficial role of uptake hydrogenase is not yet established and more experiments are needed to determine the role of Hup in this symbiosis. Four future experiments are suggested.
title: Transforming Liturgies: the autoethnography of a prison chaplain

description: Much has been written about chaplaincy, but little about prison chaplaincy, and even less about prison chaplaincy by the chaplain. Within the UK the Anglican male voice dominates. This research project offers four distinct perspectives: a Scottish voice; a prison chaplain's voice (compared to that of chaplaincy); a feminist voice; and, shaped by the latter, an autoethnographic voice. The impetus for the project was the commitment of the Scottish Prison Service (SPS), following the Organisational Review of 2013, to "Transforming Lives". The change in how somebody thinks and behaves is not only central to Christian transformation but to that of desistance theory. The question faced by prison chaplains is "what is my transformational role in an organisational culture where custody and order take primacy over care and opportunity"? What transformational opportunities exist in a custody setting and how do I understand my role in the encounters I have? Most of the data was gathered by journalling through, and shaped by, the Church Year of 2017-18. Drawing on feminist qualitative research methods, six autoethnographic pieces were crafted to portray a variety of situations, encounters, and issues within the prison setting. As a spiritual practice, repeated attention was then paid to these pieces to discern patterns, nuance and significance. James K.A. Smith’s concept of "liturgies" (the work of the people) is used to frame the contrasting ways of encountering people and the potential for transformation in those meetings. The underlying worldview of chaplain and prison are examined, and the resulting liturgies identified – some graceful, some disgraceful. The reality of tension, cooperation and complicity are revealed in the day-to-day work of the chaplain as an employee of the SPS. The unseen and unspoken witnessing of trauma emerges as a powerful liturgy amongst a prison population representing some of the most marginalised in society. The importance and distinctive liturgical nature of making fragmented spaces for Sanctuary and Sabbath for all, are emphasised. Finally, the chaplain's practice of transformative liturgies is associated with the "new person" emerging from Bandura's work on self-efficacy and thus with desistance theory. Identifying the transformative in everyday liturgies has radical implications for how people are treated inside prison and how they are welcomed into our church and community once released.

description: Korean Kim-Chi has been famous for the best quality and taste all around world. However, the market share of Korean Kim-Chi in domestic markets is decreasing recently due to the low price and high quality Chinese Kim-Chi import. The condition of Kim-Chi production & export in china has been changed due to Korean Kim-Chi plants and equipment have been transferred to china with manufacture process, In addition, WTO/DDA agricultural negotiations in progressing will be predicted to give more effects on Korean Kim-Chi industry than those of UR negotiations on agriculture. This paper aims to establish forecasting simulation model and particularly analyze the impacts of Chinese Kim-Chi import on Korean Kim-Chi industry. This study points out the future economic indexes of the Korean Chinese Cabbage including Kim-Chi in detail such as production, consumption, import & export, income by scenario based on the modalities for agricultural negotiation.

description: The Nernst effect of Pr$_{2-x}$Ce$_{x}$CuO$_4$ (x=0.13, 0.15, and 0.17) has been measured on thin film samples between 5-120 K and 0-14 T. In comparison to recent measurements on hole-doped cuprates that showed an anomalously large Nernst effect above the resistive T$_c$ and H$_{c2}$ \cite{xu,wang1,wang2,capan}, we find a normal Nernst effect above T$_c$ and H$_{c2}$ for all dopings. The lack of an anomalous Nernst effect in the electron-doped compounds supports the models that explain this effect in terms of amplitude and phase fluctuations in the hole-doped cuprates. In addition, the H$_{c2}$(T) determined from the Nernst effect shows a conventional behavior for all dopings. The energy gap determined from H$_{c2}$(0) decreases as the system goes from under-doping to over-dopingin agreement with the recent tunnelling experiments.
title: The interaction of platelets and exogenous antigenic factors in the causation of atherosclerosis and coronary heart disease
Creators: name: Glanmor Rees, B. W.
Publisher: name: The Open University
Year: 1984

description: This work describes aspects of the role of platelets in the development of atherosclerosis and coronary heart disease (CHD). Emphasis is on the involvement of "young" platelets, which are metabolically more active than the other population of these cells and are consequently termed "active" platelets. Aggregation investigations were used to detect an increase in this fraction of the platelet population and electron microscope studies confirmed that these aggregation results reflected the total activity of the platelets. Surveys performed in conjunction with the Medical Research Council Epidemiology Unit showed abnormal results in approximately 18% of the normal population and in approximately 90% of CHD patients. This latter group was tested at least twelve months after recovery from the heart attack (myocardial infarction). There are immunological factors which may be important and are investigated in this work. The involvement of these factors are indicated by the report relating antibody to whole dried milk with CHD. This original observation was confirmed in surveys performed in collaboration with the Medical Research Council Epidemiology Unit. Because of the large number of specimens involved in these surveys, an automated method was developed. This method was also used to survey the distribution of food antibodies in the normal population. It was found that the milk antibody originally related to CHD was produced in response to an antigen present in the cream portion of milk. It was determined that the antigen resided in the bovine milk-fat globule-membrane. Because it has previously been shown that cross-reactivity exists between membranes of different species, the possibility of antibody to bovine milk-fat globule-membrane reacting with human platelets was considered and the resulting investigations, which demonstrated this occurrence, are described. The possibility is considered that increased platelet turnover in this disease, with an increased percentage of "active" platelets, may well be the result of the action of antibody to bovine milk-fat globule-membrane. Interaction between membranes may therefore play a role in the development of atherosclerosis.

description: The income increment policy in the 1980s was different from that in the 1970s, which was a sort of support price policy. It aimed to increase the income of agrarian households by producing new highly value added products or earning non-farming income. But it didn't aim the renovation of agricultural structure. Although the free trade system was introducing in the 1980s, the agrarian policy did not change its orientation from that in the 1970s. The target of the agrarian policy in the 1980s was the rural development under the low price system for agricultural products, but it was a impossible dream. The agrarian policies without renovation overcoming small farming led to the failure of the complex farming. Agrarian households fell into a heap of debts. The complex project to develop agrarian and fishing villages since 1989 oriented restructuring the agrarian structure.

 COMMENTS. The puparia of this species secrete clear, glassy, material around and over themselves: when alive they have a shiny, “laquered” appearance, with a narrow line of opaque wax issuing from each of the three tracheal openings at the puparial margin. A. cococolus is very common in Central America, but the puparia have not been observed in aggregations. The puparia of some samples display detail variations that may be specific differences and Aleuroplatus spp 11 and 13 from Belize (Appendix 1), in particular, are morphologically very similar to A. cococolus.

description: A new ro-vibrational line list for the ground electronic state of the main isotopologue of acetylene, $^{12}$C$_2$H$_2$, is computed as part of the ExoMol project. The aCeTY line list covers the transition wavenumbers up to 10,000 cm$^{-1}$ ($ λ>1$ $μ$m), with lower and upper energy levels up to 12,000 cm$^{-1}$ and 22,000 cm$^{-1}$ considered, respectively. The calculations are performed up to a maximum value for the vibrational angular momentum, $K_{\rm max}=L_{\rm max}$ = 16, and maximum rotational angular momentum, $J$ = 99. Higher values of $J$ were not within the specified wavenumber window. The aCeTY line list is considered to be complete up to 2200 K, making it suitable for use in characterising high-temperature exoplanet or cool stellar atmospheres. Einstein-A coefficients, which can directly be used to calculate intensities at a particular temperature, are computed for 4.3 billion (4,347,381,911) transitions between 5 million (5,160,803) energy levels. We make comparisons against other available data for $^{12}$C$_2$H$_2$, and demonstrate this to be the most complete line list available. The line list is available in electronic form from the online CDS and ExoMol databases.

description: Various types of agricultural organizations and institutions have appeared due to severe competition in agricultural markets and changes in consumers' preference for food. Production and marketing contracts , producers' organizations, and collective sales by producers may be good examples. The basic role of agricultural economics is to explain how such things works. In this context, a brief structure of the Transaction Cost Economics (TCE) is reviewed and the potential contributions of the TCE to agricultural economic research is suggested. Although there are some empirical research limitations, the paper argues, TCE would be a good tool for analyzing agricultural contract, agricultural cooperatives and producers' organizations, vertical integration, standardization and grading system of agricultural products, and agribusiness.

description: The purpose of this paper is to investigate the current situation of management and transaction in the agricultural product e-commerce, and to analyze impacts of farmers characteristics and marketing strategies on the management performance in the e-commerce sector. The major findings and policy implications are as followings; In the first, factors that play a major role on increases in the ratio of sales volume with e-commerce would be analyzed. In the second, the absolute sales volume of agricultural products through the e-commerce in the farm households would be dependent on the degree of consumer information, CRM, and the education level of farmers. In the third, the degree of using consumer information and CRM, simultaneously, have a great effect on both the absolute sales volume and the ratio of sales volume with e-commerce. As policy implications, finally, for improving activities in the agricultural product e-commerce, the government policy program should be re-organized with respect to the development stage of individual farmers.

description: Γενικά: Η ανδρογενετική αλωπεκία είναι μια από τις συχνότερες παθήσεις και προσβάλλει και τα δύο φύλα σε όλες τις φυλές. Παρόλα αυτά η παθογένειά της δεν είναι πλήρως διευκρινισμένη. Ο σκοπός της μελέτης αυτής ήταν να διερευνήσει το ρόλο των τεσσάρων μείζονων προσταγλανδινών (PGE2, PGD2, PGF2α και PI2 ή προστακυκλίνης) στην παθογένεια της ανδρογενετικής αλωπεκίας (AGA) σε άνδρες και γυναίκες. Μέθοδοι: Λήφθηκαν βιοψίες από το τριχωτό της κεφαλής 30 ενηλίκων (17 ανδρών και 13 γυναικών) που έπασχαν από AGA και από 30 υγιών ενηλίκων (18 άνδρες και 12 γυναίκες). Από κάθε ασθενή λήφθηκαν 2 βιοψίες, μία από τη μετωπιαία πάσχουσα περιοχή και μία από την ινιακή περιοχή φυσιολογικής τριχοφυίας. Από τους υγιείς λήφθηκαν επίσης βιοψίες από τα ίδια σημεία. Σε κάθε ιστικό δείγμα μετρήθηκαν τα επίπεδα κάθε προσταγλανδίνης ξεχωριστά. Αποτελέσματα: Στην ομάδα των ασθενών τα επίπεδα της PGD2 και της προστακυκλίνης ήταν αυξημένα στην περιοχή της αλωπεκίας συγκρινόμενα με τα αντίστοιχα στην περιοχή φυσιολογικής τριχοφυίας. Αντιθέτως οι PGE2 και PGF2α φάνηκαν μειωμένες στις περιοχές της AGA συγκρινόμενες με τις υγιείς περιοχές.Συμπέρασμα: Τα αποτελέσματα αυτά υποστηρίζουν ότι υπάρχει μια λεπτή ισορροπία μεταξύ των τεσσάρων αυτών μορίων στους θύλακες του τριχωτού της κεφαλής και η διατήρησή της πιθανώς να είναι πολύ σημαντική για την ανάπτυξη των τριχών. Επιπρόσθετα, οι υποδοχείς τους μπορεί να αποτελέσουν μελλοντικούς θεραπευτικούς στόχους για την ανδρογενετική αλωπεκία.
description: Background: Though androgenetic alopecia is one of the most common diseases affecting both sexes and all races, its pathogenesis is not completely clarified. The aim of this study was to investigate the role of the four major prostaglandins (PGE2, PGD2, PGF2α, PI2 or prostacyclin) in the pathogenesis of AGA in males and females. Methods: Human scalp biopsies were obtained from 30 adults (17 males and 13 females) suffering from AGA and from 30 healthy adults (18 males and 12 females). In each subject 2 skin biopsies were performed, one from the frontal bald area and another one from the occipital area with normal hair growth. In healthy group biopsies were taken from both areas too. In each sample all four prostaglandins were measured. Results: In the patients group PGD2 and prostacyclin or PGI2 levels were increased in bald compared to haired scalp. On the contrary, measurements of PGE2 and PGF2α showed that they were diminished in bald areas compared to haired areas. Prostaglandins levels in healthy samples were comparable to the haired areas. Conclusion: These results support that there is a fine balance between these 4 proteins in scalp hair follicles and its maintenance may be crucial for hair growth. Furthermore their receptors could be potential targets for treatment of AGA.

description: This paper contains the main results of a FAO study on staple food prices and real wages in Afghanistan during the period 1996-2002, based on information systematically collected weekly by WFP in all major cities (Kabul, Kandahar, Jalalabad, Herat, Mazar-e-Sharif and Faizabad). The main conclusion of the study are as follows: Large fluctuations have been registered in food prices. However, the fluctuations were mostly due to changes in the value of currency, i.e. in the exchange rate. Food prices in dollars have been remarkably stable, especially during the years 2001 and 2002. During the war years, disrupted markets and international isolation caused prices to be well above international levels. But during 2001 and 2002 prices of wheat have been in line with international prices. There is no evidence that increased production and increased food aid in 2002 may have depressed domestic prices. Wheat price in dollars in 2002 has been approximately the same than in 2001, in spite of large increases in food aid and an even larger increase in domestic production. Commercial imports have acted as price regulators, keeping domestic prices more or less stable. The purchasing power of wages for unskilled urban labour (in terms of bread) has remained remarkably stable from 1998 to 2001. One day's wage has been equivalent to the cost of approximately 4 Kg of bread, with a slightly better situation in Kabul than in other cities. Faizabad was the city with wages at the lowest level of purchasing power. During the first half of 2002 the purchasing power of wages (i.e. the real wage level) increased significantly in all cities, reaching a level of 7-8 Kg of bread at mid-year. During the last months of the year (September-December) there has been no further increase in real wages, except in Faizabad that has continued recovering. In the case of Kabul, real wages have fallen significantly in October-November, back to the levels of 2001, i.e. about 5 Kg of bread equivalent per day. This indicates saturation of the urban labour market, and increased food insecurity of the urban population. The study recommends urgent start of labour-intensive public works to help improving the real wage of urban workers, and therefore reducing food insecurity in urban areas.

description: This article explores the role of migrant networks in Mexican rural out-migration focusing on how network composition influences rural-to-rural, rural-to-urban, and rural-to-international migration. Using data from rural Mexico, migration is considered in a multiple-choice context allowing for the possibility that rural Mexicans can migrate within Mexico for agricultural and non-agricultural employment as well as to the United States. Our principle result is that the parts are greater than the whole; using disaggregated measures of migrant networks highlights the complexity of network effects on migration decisions. When modelling the migration choice with aggregate measures, US migrant networks appear more important than Mexico migrant networks. Once networks are disaggregated, however, certain types of Mexico migrant networks become very important in the decision to migrate within Mexico. Further, the impact of migrant networks in the decision to migrate is not homogeneous; the closer the bond, the greater the impact on the migration decision.

description: This study was carried out to investigate the manner in which this technological innovation was being implemented in a cross section of schools in England and Wales. Ultimately it was to ascertain the pedagogical approach employed, and if the promised revolution in teaching and learning procedures, attributed to the use of the microcomputer in education was forthcoming. The contribution to societal needs was also investigated, and gender differences in pupil's attitude to using the microcomputer. Suitability of chosen equipment, courseware, and problems encountered were especially sought; the result of any such problems or inefficiencies could be responsible for the efficacy or otherwise of the method. Areas where further research was required were established. The thesis is not of the hypothesis testing type, but more a series of case studies. The findings are that: (a) While the pedagogical approach mainly follows the traditional method of teaching, there is developing, in some classrooms, a change in emphasis on how children are learning. (b) Some upper schools especially, are attempting to fulfil societal needs by changing the content of computer courses. (c) While a notable difference develops in the attitude of boys and girls to using computers, girls, especially in the upper schools, are becoming more interested in specific topics that are being introduced. (d) Future educational software programs need to react intelligently to pupil's requirements; the microcomputers mainly in use at present are unsuitable. Overall they have not helped the case for computer aided learning. (g) The use of the microcomputer in the classroom is increasing and staff resistance to using it is diminishing, despite a lack of evaluation as to its effectiveness. (f) Perusal of educational software reveals the lack of systematic planning at the development stage. Further research areas would be to investigate the following: the reasons for and policies to counteract gender differences, the formulation of evaluation techniques, the possibility of the use of intelligent knowledge-based systems in the classroom.

description: This paper considers the impact of the nutritional status on the growth rate of real GDP per capita. In particular, a panel of 114 countries' Dietary Energy Supply (DES) per capita from 1961 to 1999 is combined with the latest release of real GDP per capita data from the World Bank (World Development Indicators, 2001). Besides pooled regressions, we also divided at the sample into a 10-year and 5-year interval in order to investigate the medium and short run effects. Moreover, we compared and contrasted across country groups within each of the above time frames to discern cross-sectional performance difference. We found that on average the long run real GDP per capita growth rate can be increased by 0.5 percentage point if DES is increased by 500 kcal/day. However, for a subgroup of developing countries (East and Southeast Asia) we found this number could be four times larger, while in most of the other developing countries this effect is either negative or negligible. The short run effect is more likely to be insignificant or negative than long run effect. We believe this could be due to the dynamic interaction between the short run population growth effect and the long run productivity effect. These results are robust to various econometric modeling procedures as well as to the identity critique. Since this nutrition trap is a short run effect, any policy shall aim to reduce hunger for the long run. This study shows that having chronic hunger in the country is costly in terms of economic growth in the long run.

description: The astrophysical origin of gravitational wave (GW) events is one of the most timely problems in the wake of the LIGO/Virgo discoveries. In active galactic nuclei (AGN), binaries form and evolve efficiently by dynamical interactions and gaseous dissipation. Previous studies have suggested that binary black hole (BBH) mergers in AGN disks can contribute significantly to BBH mergers observed by GW interferometers. Here we examine the distribution of the effective spin parameter $χ_\mathrm{eff}$ of this GW source population. We extend our semi-analytical model of binary formation and evolution in AGN disks by following the evolution of the binary orbital angular momenta and black hole (BH) spins. BH spins change due to gas accretion and BH mergers, while the binary orbital angular momenta evolve due to gas accretion and binary-single interactions. We find that the distribution of $χ_\mathrm{eff}$ predicted by our AGN model is similar to the distribution observed during LIGO/Virgo O1 and O2. On the other hand, if radial migration of BHs is inefficient, $χ_\mathrm{eff}$ is skewed toward higher values compared with the observed distribution, because of the paucity of scattering events that would randomize spin directions relative to the orbital plane. We suggest that high binary masses and the positive correlation between binary mass and the standard deviation of $χ_\mathrm{eff}$ for chirp masses up to $\approx 20$ $\mathrm{M}_\odot$, can be possible signatures for mergers originating in AGN disks. Finally, hierarchical mergers in AGN disks naturally produce properties of the recent GW event GW190412, including a low mass ratio, a high primary BH spin, and a significant spin component in the orbital plane.

description: As part of daily interactions humor is an integral element of work relationships with consequences for well-being or turnover intentions. However, its adequate assessment in the work context has yet to be improved. While the Humor Styles Questionnaire (HSQ; Martin et al. 2003. Individual differences in uses of humor and their relation to psychological well-being: Development of the Humor Styles Questionnaire. Journal of Research in Personality 37. 48–75) covers adaptive and maladaptive functions of humor styles, it assesses humor in general life. With the adaption of the HSQ, that is, the short (12-item) and workrelated version of the HSQ (swHSQ), we provide an efficient tool for the assessment of individual humor styles in the work context. We validated and tested the swHSQ in two Austrian-German and one U.S. sample and analyzed its structure and impact by means of confirmatory factor analyses as well as regression analyses. The swHSQ seems valid and reliable (α between 0.62 and 0.86) in a German and an English version, thus representing an efficient selfreport tool for field research. Evidence for construct validity is provided with regard to humor styles’ associations with optimism, occupational self-efficacy, irritation, and job satisfaction. While the positive (affiliative, self-enhancing) humor styles showed expected relationships with the outcomes, patterns of relationships of the negative styles suggest intercultural differences in workplace humor. Thus, self-defeating but not aggressive humor seems impactful in the Austrian-German sample, while the contrary was found in the U.S. sample.

description: In an effort to eliminate laser phase noise in laser interferometer spaceborne gravitational wave detectors, several combinations of signals have been found that allow the laser noise to be canceled out while gravitational wave signals remain. This process is called time delay interferometry (TDI). In the papers that defined the TDI variables, their performance was evaluated in the limit that the gravitational wave detector is fixed in space. However, the performance depends on certain symmetries in the armlengths that are available if the detector is fixed in space, but that will be broken in the actual rotating and flexing configuration produced by the LISA orbits. In this paper we investigate the performance of these TDI variables for the real LISA orbits. First, addressing the effects of rotation, we verify Daniel Shaddock's result that the Sagnac variables will not cancel out the laser phase noise, and we also find the same result for the symmetric Sagnac variable. The loss of the latter variable would be particularly unfortunate since this variable also cancels out gravitational wave signal, allowing instrument noise in the detector to be isolated and measured. Fortunately, we have found a set of more complicated TDI variables, which we call Delta-Sagnac variables, one of which accomplishes the same goal as the symmetric Sagnac variable to good accuracy. Finally, however, as we investigate the effects of the flexing of the detector arms due to non-circular orbital motion, we show that all variables, including the interferometer variables, which survive the rotation-induced loss of direction symmetry, will not completely cancel laser phase noise when the armlengths are changing with time. This unavoidable problem will place a stringent requirement on laser stability of 5 Hz per root Hz.

Λαμβάνοντας υπόψη το γεγονός ότι η συγκεκριμένη Σχολή ήδη από την ίδρυσή της χαρακτηρίζεται για το προοδευτικό της πνεύμα, οι εκάστοτε αλλαγές στην εσωτερική δομή της προκαλούν μεγάλο ενδιαφέρον. Σκοπός της εργασίας είναι η ανασκόπηση των αλλαγών στη διάρθρωση της Σχολής που έλαβαν χώρα αυτό το διάστημα, η διερεύνηση των βαθύτερων αιτιών για τις οποίες αποφασίστηκαν οι συγκεκριμένες αλλαγές σε συνάρτηση με τις κοινωνικο-πολιτικές συγκυρίες και τις εκπαιδευτικές ανάγκες, η κριτική παρουσίαση των απόψεων που εκφράστηκαν την περίοδο αυτή από όλους τους φορείς που σχετίζονται με τη Σχολή, καθώς και η διερεύνηση των απόψεων των καθηγητών και καθηγητριών της Σχολής, εν ενεργεία και μη, για την εκάστοτε δομή της και τη σημερινή οργάνωση των Τμημάτων της. Μέσα από τη συγκεκριμένη έρευνα, λοιπόν, προσδοκάται να αναδειχθούν τα αίτια και η αναγκαιότητα ή μη της εκάστοτε αλλαγής της εσωτερικής δομής/οργάνωσης της Φιλοσοφικής Σχολής Θεσσαλονίκης από τη δεκαετία του 1970 έως και σήμερα, καθώς και να προταθούν νέοι τρόποι οργάνωσης των σπουδών στη Σχολή που πιθανόν να βελτίωναν το έργο της και τον προορισμό της.
description: The subject of this thesis is the structure of the Faculty of Philosophy of Thessaloniki regarding the separation of its Departments and the specializations it provides in each time period, starting from the 1970s and reaching until today. Taking into account the fact that this Faculty has been characterized for its progressive spirit since its foundation, the changes in its internal structure are of great interest. The purpose of this thesis is to review the changes in the structure of the Faculty that took place during this period, to investigate the deeper reasons for which the specific changes were decided in relation to the socio-political circumstances and the educational needs, the critical presentation of the views expressed during this period by all bodies related to the Faculty, as well as the investigation of the views of the professors of the Faculty, active and not, for its respective structure and the current organization of its Departments. Through this research, it is expected to highlight the causes and the necessity or not of each change in the internal structure/organization of the Faculty of Philosophy of Thessaloniki from the 1970s until today, as well as to propose new ways of organizing studies at the Faculty that would probably improve its work and its destination.

description: We analyze a Josephson junction between two superconductors interconnected through a normal-state nanostructure made of two parallel nanowires with embedded quantum dots. We study the influence of interference effects due to the Aharonov-Bohm (AB) and Aharonov-Casher (AC) phases for local and nonlocal (split) Cooper pairs. In the AB effect the phase of electron is affected by magnetic flux, while in the AC effect the phase of the electron in solid state can be modified due to the Rashba spin-orbit coupling. In the low-transmission regime the AB and AC effects can be related to only local or nonlocal Cooper pair transport, respectively. We demonstrate that by the addition of the quantum dots the Cooper pair splitting can be made perfectly efficient, and that the AC phase is different for non-spin-flip and spin-flip transport processes.

Hard Exclusive Electroproduction of $π^+π^-$ Pairs

description: Hard exclusive electroproduction of $π^+π^-$ pairs off hydrogen and deuterium targets has been studied by the HERMES experiment at DESY. Legendre moments $$ and $$ of the angular distributions of $π^+$ mesons in the center-of-mass frame of the pair have been measured for the first time. Their dependence on the $π^+π^-$ invariant mass can be understood as being due to the interference between relative $P$-wave (isovector) and $S,D$-wave (isoscalar) states of the two pions. % The increase in magnitude of $$ as Bjorken $x$ increases is interpreted in the framework of Generalized Parton Distributions as an enhancement of flavour {non-singlet} $q\bar{q}$ exchange for larger values of $x$, which leads to a sizable admixture of isoscalar and isovector pion pairs. % In addition, the interference between {$P$-wave} and {$D$-wave} states separately for transverse and longitudinal pion pairs has been studied. The data indicate that at {$\la Q^2 \ra = 3 $ GeV$^2$} higher twist effects can be as large as the leading-twist longitudinal component

 Hempelia chivelensis Sampson & Drews, 1941: 166. Syntypes, Mexico.
DISTRIBUTION. Neotropical Region: Belize, Mexico.
 COMMENTS. As discussed in the generic diagnosis, above, the puparial characteristics of this species agree with the generic definition of Aleurothrixus, as interpreted here, leading to the decision to propose Hempelia as a junior synonym of Aleurothrixus. Puparia usually develop in distinct aggregations, which is a characteristic often observed in other species of Aleurothrixus.
 Aleurothrixus sp. 2 (Fig. 135, see Appendix 1), represented in BMNH by material from both Belize and Nicaragua, is similar to A. chivelensis but the marginal teeth are coarser and the vasiform orifice is surrounded by figure of characteristic shape.

description: International Heat, a team of five graduate students, spent the past four months designing a thermal cautery system capable of being used for open abdominal surgery in low-resource settings. Throughout those four months, the team followed the design process outlined in Biodesign: The Process of Innovating Medical Technologies. Potential project ideas were presented to the entire Engineers-in-Scrubs class. International Heat formed from a desire to create a device with the potential to significantly impact the quality of medical care in third world countries. This report details the team’s progression starting with defining the team’s mission statement and strategic focus, to the needs finding process, to needs screening and creation of preliminary needs specifications, to concept generation and screening, to interviewing clinicians who provided feedback leading to the update of the needs statement and needs specifications, and then final concept selection. We describe the prototyping of and evaluation of two separate concepts in order to ultimately choose thermal cautery as well as extensive feasibility testing we performed to see if thermal cautery had the potential to be a viable alternative to an electrosurgical unit. Finally, we provide a potential development strategy which could be implemented to bring the thermal cautery unit to market.

(Figs 14, 97)
 Aleurothrixus myrtacei Bondar, 1923: 176. Syntypes, Brazil.
DISTRIBUTION. Neotropical Region: Barbados, Belize, Brazil, Guadeloupe.
 COMMENTS. A. myrtacei has puparia with finer marginal teeth and shorter submedian setae than in A. floccosus, but it shares the characteristic gregarious habit of the immature stages, which are usually found in discreet, crowded, groups. Two Brazilian puparia in BMNH (which are probably syntypes, see Martin, 2004:56), have their eighth abdominal and caudal setae shorter and stouter than those of Belize specimens; however, specimens in BMNH from guava in Barbados have these setal pairs intermediate in form and this is considered to be intraspecific variation.
 Aleurothrixus sp 1 (see Appendix 1) closely resembles A. myrtacei, differing only in the very dark puparial cuticle. A. myrtacei may exhibit variation in the degree of puparial pigmentation, as seen in some populations of A. floccosus (see discussion of A. floccosus, above).

description: Encouraged by experiments on $^4$He in aerogels, we confine planar spins in the pores of simulated aerogels (diffusion limited cluster-cluster aggregation) in order to study the effect of quenched disorder on the critical behavior of the three-dimensional XY model. Monte Carlo simulations and finite-size scaling are used to determine critical couplings $K_c$ and exponents. In agreement with experiments, clear evidence of change in the thermal critical exponents $ν$ and $α$ is found at nonzero volume fractions of impurities. These changes are explained in terms of {\it hidden} long-range correlations within disorder distributions.
