The effects of fire on Tasmania's west coast lowland rainforest
Creators: name: Barker, Mirranie Jane
Publisher: name: University Of Tasmania
Year: 2023

description: This study examined the effects of extensive fires on lowland cool temperate rainforest burnt in 1982. Post-fire vegetation eight years after the fires was dominated by sclerophyll species. On burnt sites, there were more non-rainforest species than rainforest species, though there was regeneration of most rainforest vascular species. Rainforest species that did not appear to regenerate include species of Hymenophyllum, Asplenium and Polyphlebium. Many regenerating canopy species, especially Atherosperma moschatum, were recorded as small seedlings. Their rate of survival to maturity was unknown. Floristic analyses using ordination and classification procedures indicated that rainforest type and burn intensity were the most important variables in determining post-burn vegetation. Regression analysis also showed the importance of rainforest type and fire intensity on individual species. The dominant post-burn species were the non-rainforest species Pterklium esculentum, Leptospermum scoparium and the doubtful-rainforest species Gahnia grandis. The density of P. esculentum was greatest in callidendrous rainforest, while the other dominant species were denser in implicate rainforest (Jarman et al. 1984). Recovery of rainforest species was predominantly by seedlings, though sprouting was important for some species. Eleven rainforest tree and shrub species were recorded sprouting, with the majority of sprouting occurring in implicate rainforest. Recently burnt rainforest had a large component of sclerophyllous species and was considered to be more pyrogenic than mature rainforest. Rainforest regenerating after a recent fire would have burnt in milder conditions than those required for a large scale rainforest fire. Further fires appeared to be the major threat to the regeneration of rainforest as fires resulted in an increased sclerophyllous component and decreased rainforest elements. Additional fires also increased the time taken for rainforest to regenerate fully. The time necessary for the regeneration of rainforest and its future composition in the study areas are not certain. To enable regeneration to mature rainforest a disturbance-free period of at least 100 years is required. This study indicated that lowland rainforest can recover after a major disturbance, such as fire. It is essential that subsequent fires be excluded until the areas burnt are fully regenerated to rainforest, otherwise there will be an increase in the time required for rainforest to fully regenerate. The more fires the longer the period required for rainforest to regenerate fully with a decrease in the number of species regenerating. To ensure that subsequent fires do not occur responsible management by all land managers is required.

description: The geoeffective magnetic cloud (MC) of 20 November 2003, has been associated to the 18 November 2003, solar active events in previous studies. In some of these, it was estimated that the magnetic helicity carried by the MC had a positive sign, as well as its solar source, active region (AR) NOAA 10501. In this paper we show that the large-scale magnetic field of AR 10501 had a negative helicity sign. Since coronal mass ejections (CMEs) are one of the means by which the Sun ejects magnetic helicity excess into the interplanetary space, the signs of magnetic helicity in the AR and MC should agree. Therefore, this finding contradicts what is expected from magnetic helicity conservation. However, using for the first time correct helicity density maps to determine the spatial distribution of magnetic helicity injection, we show the existence of a localized flux of positive helicity in the southern part of AR 10501. We conclude that positive helicity was ejected from this portion of the AR leading to the observed positive helicity MC.

description: We present a new one parameter family of second derivative discontinuous solutions to the simplest scale invariant linear ordinary differential equation. We also point out how the construction could be extended to generate families of higher derivative discontinuous solutions as well. The discontinuity can occur only for a subset of even order derivatives, viz.,2nd, 4th, 8th, 16th, ....The solutions are shown to break the discrete parity (reflection) symmetry of the underlying equation. These results are expected to gain significance in the contemporary search of a new {\em dynamical principle} for understanding complex phenomena in Nature.

description: If $R$ is a valuation domain of maximal ideal $P$ with a maximal immediate extension of finite rank it is proven that there exists a finite sequence of prime ideals $P=L_0\supset L_1\supset...\supset L_m\supseteq 0$ such that $R_{L_j}/L_{j+1}$ is almost maximal for each $j$, $0\leq j\leq m-1$ and $R_{L_m}$ is maximal if $L_m\ne 0$. Then we suppose that there is an integer $n\geq 1$ such that each torsion-free $R$-module of finite rank is a direct sum of modules of rank at most $n$. By adapting Lady's methods, it is shown that $n\leq 3$ if $R$ is almost maximal, and the converse holds if $R$ has a maximal immediate extension of rank $\leq 2$.
Isolation and study of two mutants affecting motor activity in Drosophila melanogaster.

Publisher: name: University of British Columbia

description: Mitants of Prosophila melanogaster which are paralysed by exposure to one temperature, but recover mobility at another temperature may aid in the investigation of the neural and muscular components which govern motor activity. With the help of a mechanical screening method, a recessive sex-linked temperature-sensitive paralytic mutant (parats -53°9) was discovered among the progeny of ethyl methane- sulphonate-treated males and attached-X females. Parats flies which had been raised at 22°C were paralysed within 5 seconds after transfer to 29°C, but quickly regained mobility when returned to 22°C. When left at 29°C for prolonged periods, the flies gradually regained mobility. Further studies indicated that the time required for recovery following an increase in temperature was directly related to the magnitude and rate of the temperature rise. Temperature-sensitive paralysis was seen only in adult flies. The abnormal movements which are characteristic of the behavioural mutants Hk1P, Hk2T , Sh⁵, when linked to parats in males,were quickly stopped and started by temperature shifts from 22°C to 29°C and 29°C to 22°C, respectively. The possible significance of these observations is discussed. parats/M(1)0 females exhibited temperature-sensitive paralysis. The possibility that the chromosome bearing the M(1)0 mutation might also carry a deletion or mutant allele of parats has not yet been investigated. A sex-linked dominant mutation which caused abnormal movements of the head and appendages under ether anaesthesia as well as shuddering movements in unetherised flies was also discovered. The mutation was called Shuddering (Shu – 55.1). The shuddering movements could be temporarily suppressed by feeding the flies media containing LiCl but not NaCl, NH₄Cl or KCl. The evidence presented in this and other studies suggests that the effects of parats and Shu mutations upon motor activity are mediated through their effects upon the nervous system.

description: We present the results of the analysis of two Chandra observations of Circinus X-1 performed in 2007, for a total exposure time of ~50 ks. The source was observed with the High Resolution Camera during a long X-ray low-flux state of the source. Cir X-1 is an accreting neutron-star binary system that exhibits ultra-relativistic arcsec-scale radio jets and an extended arcmin-scale radio nebula. Furthermore, a recent paper has shown an X-ray excess on arcmin-scale prominent on the side of the receding radio jet. In our images we clearly detect X-ray structures both on the side of the receding and the approaching radio jet. The X-ray emission is consistent with being from synchrotron origin. Our detection is consistent with neutron-star binaries being as efficient as black-hole binaries in producing X-ray outflows, despite their shallower gravitational potential.

description: We predict the generation of noncritically squeezed light through the spontaneous rotational symmetry breaking occurring in a Kerr cavity. The model considers a $χ^{(3)}$ cavity that is pumped by two Gaussian beams of frequencies $ω_{1}$ and $ω_{2}$. The cavity configuration is such that two signal modes of equal frequency $ω_{\mathrm{s}}=(ω_{1}% +ω_{2})/2$ are generated, these signal fields being first order Laguerre--Gauss modes. In this system a spontaneous breaking of the rotational symmetry occurs as the signal field corresponds to a Hermite--Gauss TEM mode. This symmetry breaking leads to the perfect and non--critical (i.e., non dependent on the parameter values) squeezing of the angular momentum of the output TEM mode, which is another TEM mode spatially orthogonal to that in which bright emission occurs.

description: We consider the creation of superpositions of macroscopically distinct states by a completely-positive (CP) operation on a subsystem. We conclude that the subsystem on which the CP operation acts must be macroscopically large if the success probability of the CP operation does not vanish in the thermodynamic limit. In order to obtain this conclusion, we show two inequalities each of which represents a trade-off relation among the magnitude of an indicator for superpositions of macroscopically distinct states, the success probability of a CP operation, and the volume of the subsystem on which the CP operation acts.

description: We present three measurements of the top-quark mass in the lepton plus jets channel with approximately 1.9 fb-1 of integrated luminosity collected with the CDF II detector using quantities with minimal dependence on the jet energy scale. One measurement exploits the transverse decay length of b-tagged jets to determine a top-quark mass of 166.9+9.5-8.5 (stat) +/- 2.9 (syst) GeV/c2, and another the transverse momentum of electrons and muons from W-boson decays to determine a top-quark mass of 173.5+8.8-8.9 (stat) +/- 3.8 (syst) GeV/c2. These quantities are combined in a third, simultaneous mass measurement to determine a top-quark mass of 170.7 +/- 6.3 (stat) +/- 2.6 (syst) GeV/c2.

Our preliminary results are that: (i) we confirm that Omega Centauri exibiths large star-to-star metallicity variations ($\sim$ 1.4 dex); (ii) the metallicity distribution reveals the presence of at least five stellar populations with different [Fe/H]; (iii) a clear Na-O anticorrelation is clearly observed for the metal-poor and metal-intermediate populations while apparently the anticorrelation disappears for the most metal-rich populations. Interestingly the Na level grows with iron.

thermal management system

description: The deliverable details the system specifications and requirements for the electric, electronic, and thermal management system of the powertrain. The deliverable also details the different protections of the converter, as well as the supervision and monitoring strategies. The specifications detailed in this deliverable update those defined in M6. The power converter is going to be a three-level, three-phase, modular T-type converter based on SiC and GaN semiconductors. The converter, which will be installed on top of the motor, must be compact to ensure the gravimetric and volumetric power densities declared. The volume of the converter and the various components of the IMD are detailed in this deliverable. The deliverable details the different semiconductors suitable to build the converter. Commercially available GaN devices withstand very low voltages and currents. Therefore, the document proposes two alternative strategies to solve this problem. One of the strategies is to use prototype GaN packs. Another strategy is to use several GaN transistors in parallel. The document presents a roadmap with alternatives to solve other possible problems. In addition, the document details the supervision and monitoring strategies that the converter will incorporate, as well as the different functions in the cloud. Moreover, the document deals with the thermal management system. The environmental conditions in which the converter and motor can be used are presented and discussed. Furthermore, the deliverable presents the specifications of the proposed cooling system. Finally, the report concludes with a summary of the converter specifications.

description: We study a lattice field model which qualitatively reflects the phenomenon of Anderson localization and delocalization for real symmetric band matrices. In this statistical mechanics model, the field takes values in a supermanifold based on the hyperbolic plane. Correlations in this model may be described in terms of a random walk in a highly correlated random environment. We prove that in three or more dimensions the model has a `diffusive' phase at low temperatures. Localization is expected at high temperatures. Our analysis uses estimates on non-uniformly elliptic Green's functions and a family of Ward identities coming from internal supersymmetry.

description: The Minimal Supersymmetric extension of the Standard Model provides a solution to the hierarchy problem and leads to the presence of a light Higgs. A Higgs boson with mass above the present experimental bound may only be obtained for relatively heavy third generation squarks, requiring a precise, somewhat unnatural balance between different contributions to the effective Higgs mass parameter. It was recently noticed that somewhat heavier Higgs bosons, which are naturally beyond the LEP bound, may be obtained by enhanced weak SU(2) D-terms. Such contributions appear in models with an enhanced electroweak gauge symmetry, provided the supersymmetry breaking masses associated with the scalars responsible for the breakdown of the enhanced gauge symmetry group to the Standard Model one, are larger than the enhanced symmetry breaking scale. In this article we emphasize that the enhanced SU(2) D-terms will not only raise the Higgs boson mass but also affect the spectrum of the non-standard Higgs bosons, sleptons and squarks, which therefore provide a natural contribution to the T parameter, compensating for the negative one coming from the heavy Higgs boson. The sleptons and non-standard Higgs bosons of these models, in particular, may act in a way similar to the so-called inert Higgs doublet. The phenomenological properties of these models are emphasized and possible cosmological implications as well as collider signatures are described.

description: We exploit the large number of archival HST images of 47 Tuc to examine its subgiant branch (SGB) and main sequence (MS) for signs of multiple populations. In the cluster core, we find that the cluster's SGB exhibits a clear spread in luminosity, with at least two distinct components: a brighter one with a spread that is real but not bimodal, and a second one about 0.05 mag fainter, containing about 10% of the stars. In a less crowded field 6 arcminutes from the center, we find that the MS is broadened much more than can be accounted for by photometric errors, and that this broadening increases at fainter magnitudes.

Paper recycling and education : a comparison of programs in Bangkok, Thailand and Hobart, Tasmania
Creators: name: Buachaiboon, Numtip
Publisher: name: University Of Tasmania
Year: 2023

description: The aim of this study was to examine the paper recycling programs undertaken in schools and the role of other organisations involved in these programs in Bangkok, Thailand and Hobart, Tasmania. The strategies used in both places were compared to determine whether those employed in one place could be usefully applied in another. In addition, because schools do not function in isolation from their broader communities, the thesis also considered some aspects of wider recycling education. Surveys were conducted by interviewing two groups: representatives from government, private and non-government organisations involved in paper recycling education programs, whether for schools or for the wider community, and school Principals, teachers and students. The results demonstrated that, in Bangkok, the organisations involved in paper recycling had a major role in the implementation of the programs in schools. In addition, two factors crucially affected the programs: support from the Principals and from the teachers who carried out the programs and the relationship between the organisations involved and the schools. On the other hand, in Hobart, the Principals and teachers played a major role in developing paper recycling education programs in schools. The relationship between the organisations involved in waste management and recycling and the schools was not likely to be as important as it was in Bangkok. However, there were no significant differences in the strategies employed in schools in both cities. Strategies used were the provision of recycling bins and student monitors. To educate people in the community, public campaigns about recycling in both Bangkok and Hobart were run through publications (for example, booklets and pamphlets) and through mass media (such as television). However, television advertising on recycling in Bangkok required improvement. The thesis recommended that, in Bangkok schools, paper recycling bins could be provided in every classroom to increase the effectiveness of the programs. In Hobart, study tours at recycling plants and at dump sites, and school competitions could be conducted to encourage the implementation of the paper recycling program in every school. To achieve wider community education in Bangkok, recycling information to households (for example, using refrigerator calendars) and recycling bins for households could be provided. In Hobart, more co-operation is needed among organisations to create recycling education programs both for schools and for the community in general. Financial support is a major need and was found to be a similar obstacle to the production of materials and the implementation of recycling education programs both within and outside schools in Bangkok and Hobart.

description: Tourism plays a crucial role in the economy of Southern Negros, Philippines, with beach resorts being a significant draw for both local and international visitors. This study utilizes a Concurrent Nested Design to investigate tourist satisfaction with a beach resort in Southern Negros through a mixed-methods approach. Quantitative data were gathered from 150 tourists using a structured questionnaire to assess their satisfaction with the key dimensions: service quality, cleanliness, facility maintenance, and accessibility. Qualitative insights were obtained from an in-depth interview with the resort owner, who has operational experience. The quantitative results revealed high satisfaction levels, with cleanliness and service quality being the most significant factors. Correlation analysis revealed strong interrelationships between the dimensions. The qualitative narratives provided contextual depth, illustrating the resort’s commitment to personalization, ongoing facility improvements, and the challenges of managing peak periods. This integration of quantitative and qualitative findings provides a comprehensive understanding of tourist satisfaction and highlights areas for potential enhancement. This study underscores the importance of combining numerical data with experiential insights to inform effective management practices in the tourism sector

Θηλασμός

description: Το μητρικό γάλα έχει πολλαπλά οφέλη για τη μητέρα και το νεογνό-βρέφος. Πολλοί είναι οι παράγοντες που επιδρούν στην έναρξη και στη διάρκεια του μητρικού θηλασμού. Σκοπός της παρούσας έρευνας είναι να διερευνήσει, αν το είδος τοκετού επιδρά στο μητρικό θηλασμό σε εργαζόμενες γυναίκες του υγειονομικού τομέα, διαφορετικών βαθμίδων εκπαίδευσης και θέσεων εργασίας. Το δείγμα της έρευνας ήταν 150 γυναίκες που εργάζονται στον τομέα της υγείας και έχουν γεννήσει με οποιοδήποτε είδος τοκετού τα τελευταία 5 χρόνια. Διενεργήθηκε την περίοδο μεταξύ Φεβρουαρίου-Μαΐου 2024, στο Γενικό Νοσοκομείο Θεσσαλονίκης «Ιπποκράτειο». Το εργαλείο μέτρησης είναι ένα ερωτηματολόγιο που αποτελείται από τρία επιμέρους μέρη. Στο πρώτο μέρος αξιολογήθηκαν οι δημογραφικές πληροφορίες και το μαιευτικό ιστορικό των γυναικών. Το δεύτερο μέρος αποτελείται από κάποια ερωτήματα του ερωτηματολόγιου του WHO για τα νοσοκομεία φιλικά προς τα βρέφη BFHI, ένα ερωτηματολόγιο για τις θηλάζουσες μητέρες(WHO, 2009). Το τρίτο μέρος αποτελεί ένα ερωτηματολόγιο αυτοαναφοράς το οποίο είναι αυτοσχέδιο μετά από μελέτη κάποιων ερευνών βιβλιογραφικά. Τα αποτελέσματα της έρευνας έδειξαν ότι η πλειοψηφία των γυναικών ανήκει στην ηλικιακή ομάδα των 35-44 ετών ενώ, σχετικά με τον αριθμό παιδιών, το μεγαλύτερο ποσοστό έχει 1 παιδί . Όσον αφορά την οικογενειακή κατάσταση, η πλειονότητα είναι παντρεμένη ή σε σύμφωνο συμβίωσης. Στην εκπαίδευση, το μεγαλύτερο ποσοστό των συμμετεχόντων έχει τριτοβάθμια εκπαίδευση. Επίσης, παρατηρείται ότι οι μητέρες που υποβλήθηκαν σε καισαρική τομή φαίνεται να παρουσιάζουν υψηλότερη πιθανότητα να χρησιμοποιούν υποκατάστατα μητρικού γάλακτος σε σύγκριση με τις μητέρες που επέλεξαν φυσιολογικό τοκετό. Στατιστικά, σημαντική συσχέτιση βρέθηκε ότι υπάρχει μεταξύ της πρώτης επαφής με το μωρό και των πρακτικών θηλασμού, μεταξύ της βοήθειας στο θηλασμό από το προσωπικό και τον τρόπο σίτισης του νεογνού, μεταξύ της διαμονής του νεογνού και την εδραίωση του θηλασμού και μεταξύ της ικανοποίησης με την εμπειρία του θηλασμού και τον τρόπο σίτισης του νεογνού.

description: We introduce and study a deterministic lattice model describing the motion of an infinite system of oppositely charged particles under the action of a constant electric field. As an application this model represents a traffic flow of cars moving in opposite directions along a narrow road. Our main results concern the Fundamental diagram of the system describing the dependence of average particle velocities on their densities and the Phase diagram describing the partition of the space of particle configurations into regions having different qualitative properties, which we identify with free, jammed and hysteresis phases.

Population fluctuation and changes in the quality of rock ptarmigan in Alaska
Creators: name: Theberge, John B.
Publisher: name: University of British Columbia

description: This study attempts to explain changes in abundance of rock ptarmigan (Lagopus mutus) at Eagle Creek, Alaska. It includes an analysis of population data collected from 1960 to 1969, and a test of an hypothesis: that there were no differences in the quality (survival, growth, behaviour) of rock ptarmigan chicks between years that influenced spring densities. Spring densities fluctuated between 1960 and 1969, reaching peaks in 1962 and 1968. This was the result of an orderly and generally synchronous change in the loss of birds (primarily juveniles) in winter, accompanied by changes in the production of young. Both acted together in most years to either increase or decrease numbers. Each contributed approximately equally to changes in total annual loss. Changes in the production of young were primarily caused by parallel changes in both clutch sizes and nest failures. Population regulation by direct extrinsic control appeared unlikely. Other than weasel predation on nests, no environmental factor external to the population itself appeared sufficient to explain changes in winter loss of juveniles or clutch size loss, or their synchrony. These results suggested that some internal process within the population must have been important in changing the abundance of partmigan. I tested the aforementioned hypothesis in 1967, 1968, and 1969 by examining chicks both in the wild, and in captivity. Survival, growth, and behaviour of chicks all varied between years. Changes in survival were apparently determined by unidentified parental influences (genetic or physiological) rather than by the direct influence of the environment. Growth rates were similar between years in captivity, but not in the wild, suggesting that environmental influences must have had some effect. However, neither the changes in survival of chicks in summer, nor in growth rates, could be implicated in altering subsequent spring breeding densities. Levels of agonistic and aggressive behaviour in successive cohorts of aviary chicks differed. In the similar environment of the aviary each year, these behavioural changes were attributed to undetermined parental influences (genetic or physiological). These changes in aggressive-agonistic behaviour offer the best possible explanation of changes in the. population parameters most important in altering spring breeding densities.

description: Εισαγωγή: Η οσφυαλγία αποτελεί ένα από τα πιο κοινά συμπτώματα, καθώς επηρεάζει άτομα όλων των ηλικιών. Τοπογραφικά, οσφυαλγία ορίζεται ως “ο πόνος στην οπίσθια πλευρά του κορμού από τη δωδέκατη πλευρά ως και την πτυχή των γλουτών”. Ο μη ειδικός πόνος στην οσφύ (NSLBP) εμφανίζεται συχνά και συνδέεται με τη δυσλειτουργία των μυών του κορμού. Οι μύες του πυελικού εδάφους (PFM) αποτελούν τη βάση των μυών του κορμού που περιβάλλουν τη σπονδυλική στήλη και τη λεκάνη. Πρόσφατες έρευνες υποδεικνύουν τη σημασία τους για τη σταθερότητα του κορμού και τον έλεγχο του πόνου. Στόχος: Σκοπός της παρούσας εργασίας ήταν να ερευνήσει την αποτελεσματικότητα των ασκήσεων πυελικού εδάφους σε διάφορες κλινικές παραμέτρους σε ασθενείς με οσφυαλγία. Μεθοδολογία: Η ανασκόπηση περιλαμβάνει δεδομένα από 11 τυχαιοποιημένες ελεγχόμενες μελέτες (RCTs) που επιλέχθηκαν βάσει σαφών κριτηρίων ένταξης και αποκλεισμού. Η αναζήτηση στις βάσεις δεδομένων MEDLINE (PubMed), Scopus, Google Scholar και PEDro, ενώ χρησιμοποιήθηκαν αξιόπιστα μέτρα έκβασης όπως οι κλίμακες VAS και NPRS για την ένταση του πόνου, και η ODQ για λειτουργική ανικανότητα. Αποτελέσματα: Οι ασκήσεις πυελικού εδάφους συνδυαστικά με τη συμβατική φυσικοθεραπεία ανέδειξαν στατιστικά σημαντική διαφορά στη μείωση του πόνου σε σύγκριση με την απλή φυσικοθεραπεία, αν και όχι σε κλινικά σημαντικά επίπεδα. Ωστόσο, δεν παρατηρήθηκε βελτίωση στη λειτουργική ανικανότητα. Δευτερεύοντα αποτελέσματα έδειξαν βελτίωση της μυϊκής ισχύος και αντοχής. Συμπέρασμα: Οι ασκήσεις πυελικού εδάφους μπορούν να μειώσουν τον πόνο αλλά όχι την ανικανότητα σε ασθενείς με οσφυαλγία. Η ετερογένεια των μελετών επηρεάζει την ομοιομορφία των αποτελεσμάτων, υποδεικνύοντας την ανάγκη για περισσότερες μελέτες υψηλότερης μεθοδολογικής ποιότητας με στοχευμένο σχεδιασμό. Η ανασκόπηση υπογραμμίζει τη σημασία της συνεχούς διερεύνησης για να καθοριστεί η αξία των ασκήσεων αυτών στη θεραπεία της οσφυαλγίας.

description: The abundance of potassium is derived from X-ray lines observed during flares by the RESIK instrument on the solar mission CORONAS-F between 3.53 A and 3.57 A. The lines include those emitted by He-like K and Li-like K dielectronic satellites, which have been synthesized using the CHIANTI atomic code and newly calculated atomic data. There is good agreement of observed and synthesized spectra, and the theoretical behavior of the spectra with varying temperature estimated from the ratio of the two GOES channels is correctly predicted. The observed fluxes of the He-like K resonance line per unit emission measure gives log A(K) = 5.86 (on a scale log A(H) = 12), with a total range of a factor 2.9. This is higher than photospheric abundance estimates by a factor 5.5, a slightly greater enhancement than for other elements with first ionization potential (FIP) less than about 10 eV. There is, then, the possibility that enrichment of low-FIP elements in coronal plasmas depends weakly on the value of the FIP which for K is extremely low (4.34 eV). Our work also suggests that fractionation of elements to form the FIP effect occurs in the low chromosphere rather than higher up, as in some models.

description: This deliverable focuses on monitoring gender balance within the consortium and describes the actions to be taken to ensure gender equality and ethical performance throughout the project. Relevant background on the gender perspective and the ethical considerations included in the Grant Agreement and the European Recommendations are presented. In more detail, the gender balance in the RHODaS consortium and future actions to ensure gender equality throughout the RHODaS project are also presented, as well as the ethical principles to apply in RHODaS research and development. This deliverable will therefore outline the need and importance of promoting gender balance and equality transversely and how ethics considerations are fulfilled throughout the project planning and implementation to stand out as an excellent example of a wellbalanced working community.

description: PROPOSAL FOR MFA COURSE IN PHOTOGRAPHY During the Masters course I would like to investigate deeper into the cyclic nature of existence. I intend to use flowers, fruit and seed to pursue this theme. One part of the work would continue with close-up photography, closer than my present work of surfaces of bodies. The motivation behind this kind of looking is a fascination with the richness of form and surface as well as an attempt to penetrate, to understand what lies behind these surfaces. Included in these images would be aspects of decay, of transition from one stage of existence to the next. In another part of the work I would like to deal with stillife and the symbolism of fruit flower and seed in this context. I can imagine some rather exciting theoretical investigation along with the visual work. I would like the overall mode of the work to be a celebration of life - and death, since death is an integral part of life. TRACING THE IRRATIONAL My work is motivated by an interest in elemental forms and forces of life, the 'stuff of existence' which, as I perceive it, throbs persistently and relentlessly everywhere and anywhere on this globe, even in heavily poisoned areas where, still persisting, mutants and rather grotesque new variations occur. PHOTOGRAPHY, THE PARADOX AND THE IRRATIONAL This paper is structured around the question as to how photography can deal with, explore and make visible the irrational. I will start with an explanation as to why I think I have chosen photography as my medium of operation. This will lead to an examination of the propensities of photography which particularly interest me. I will then investigate the relationship between surrealism and photography, since the surrealists were also concerned with the irrational, and close with what I, at this stage, consider to be the position of my own current work within this context.

description: We review our proposal to generalize the standard two-dimensional flatness construction of Lax-Zakharov-Shabat to relativistic field theories in d+1 dimensions. The fundamentals from the theory of connections on loop spaces are presented and clarified. These ideas are exposed using mathematical tools familiar to physicists. We exhibit recent and new results that relate the locality of the loop space curvature to the diffeomorphism invariance of the loop space holonomy. These result are used to show that the holonomy is abelian if the holonomy is diffeomorphism invariant. These results justify in part and set the limitations of the local implementations of the approach which has been worked out in the last decade. We highlight very interesting applications like the construction and the solution of an integrable four dimensional field theory with Hopf solitons, and new integrability conditions which generalize BPS equations to systems such as Skyrme theories. Applications of these ideas leading to new constructions are implemented in theories that admit volume preserving diffeomorphisms of the target space as symmetries. Applications to physically relevant systems like Yang Mills theories are summarized. We also discuss other possibilities that have not yet been explored.

description: We propose a kind of reaction-diffusion equations for cell differentiation, which exhibits the Turing instability. If the diffusivity of some variables is set to be infinity, we get coupled competitive reaction-diffusion equations with a global feedback term. The size ratio of each cell type is controlled by a system parameter in the model. Finally, we extend the model to a cascade model of cell differentiation. A hierarchical spatial structure appears as a result of the cell differentiation. The size ratio of each cell type is also controlled by the system parameter.

description: (abridged) We present deep archival VLT/FORS1+UVES spectroscopic observations of the system of two blue compact dwarf (BCD) galaxies SBS 0335-052E and SBS 0335-052W. Our aim is to derive element abundances in different HII regions of this unique system of galaxies and to study spatial abundance variations. We determine abundances of helium, nitrogen, oxygen, neon, sulfur, chlorine, argon and iron. The oxygen abundance in the brighter eastern galaxy varies in the range 7.11 to 7.32 in different HII regions supporting previous findings and suggesting the presence of oxygen abundance variations on spatial scales of ~1-2 kpc. The oxygen abundance in the brightest region No.1 of SBS 0335-052W is 7.22+/-0.07, consistent with previous determinations.Three other HII regions are much more metal-poor with an unprecedently low oxygen abundance of 12+logO/H=7.01+/-0.07 (region No.2), 6.98+/-0.06 (region No.3), and 6.86+/-0.14 (region No.4). These are the lowest oxygen abundances ever derived in emission-line galaxies. Helium abundances derived for the brightest HII regions of both galaxies are mutually consistent. We derive weighted mean He mass fractions of 0.2485+/-0.0012 and 0.2514+/-0.0012 for two different sets of HeI emissivities. The N/O abundance ratio in both galaxies is slightly higher than that derived for other BCDs with 12+logO/H<7.6. This implies that the N/O in extremely metal-deficient galaxies could increase with decreasing metallicity.
