description: CD4{u207A} T lymphocytes play an important role in the adaptive immune response that protects the host from a broad range of pathogenic microorganisms. They have the ability to differentiate into different subsets depending on the micro-environment through the actions of specific transcription factors. The work described in this thesis demonstrates that c-Rel, one of the NF-{u0199}B transcription factor family members, is required for IL-21 gene expression in CD4{u207A} T cells and also for development of IL-21 associated Th subsets. Firstly, c-Rel is involved in the regulation of IL-21 gene expression and T(FH) development. IL-21 messenger RNA and protein levels were reduced in the CD4{u207A} cells of c-Rel knock-out (rel{u207B}/{u207B}) mice when compared to wild-type (rel{u207A}/{u207A}) mice in both in vitro and in vivo models. A binding site identified in the proximal promoter of il21 was confirmed to bind c-Rel in vitro and in vivo, and to regulate the gene expression of IL-21 in T cells. The development of IL-21-dependent T(FH) and germinal centre B cell was also impaired in rel{u207B}/{u207B} mice. The administration of IL-21 protein to rel{u207B}/{u207B} mice rescued the development of TFH cells, but not germinal centre B cells. Secondly, c-ReI regulates the development of Th17 cells in experimental autoimmune encephalomyelitis (EAE). rel{u207B}/{u207B} mice were confirmed to be resistant to EAE, and were demonstrated a cell intrinsic Th17 deficiency using mixed chimera and adoptive transfer EAE experiments. c-Rel was found to act in the T cell receptor signaling pathway in the early stage of Th17 development, and to bind to the promoter of the master transcription factor of Th17 development, ROR{u03B3}t and control its expression. c-ReI was also revealed to be present in the signalling pathway of CD28 co-stimulation that causes Th17 repression. Thirdly, the number of regulatory T cells (Treg) was confirmed to be significantly reduced in rel{u207B}/{u207B} EAE mice and adoptive transfer experiments suggest that EAE development is not only associated with Th17 cell infiltration but is also dependent on the equilibrium between Th17 and Treg cells. Taken together, c-Rel plays an important role in the development of CD4{u207A} T cell subsets. It affects TFH and Th17 cell development by regulating the expression of IL-21 and ROR{u03B3}t respectively. These findings point to a novel and critical role for c-Rel in the control of CD4{u207A} T cell development and in activated T cell-dependent autoimmune responses and inflammation, and offer new potential therapeutic targets in associated autoimmune inflammatory diseases.

description: Aims: To determine the amount of mercury discharged into Namukombe stream, the major water body in Syanyonja village, Busia gold district and investigate the impacts of mercury-based artisanal and small-scale gold mining (ASGM) on the mining population and the environment.Study Design: Quantitation of mercury discharged with tailings was done by mass balance method. Field survey at the mining sites was done followed by administration of questionnaires to 50 stampeders in the village.Place and Duration of Study: The study was done in Syanyonja village in Syanyonja parish, Busitema subcounty, Samia Bugwe constituency, Busia gold district, South East of the Republic of Uganda between April 2019 to June 2019.Methodology: Fieldwork was done in Syanyonja village to appreciate the level of environmental pollution due to mercurial ASGM in the area. Quantitation of mercury discharged with tailings was done by mass balance method. Field survey at the mining sites was done followed by administration of 50 questionnaires to stampeders of at least 18 years old and ASGM experience of not less one year.Results: About 8% of mercury mixed with auriferous materials is lost in tailings, accounting for an annual mercury release of about 1.757 kg into the environment. Socio-demographic results indicated that the majority of the mining population (64%) are male and ASGM have left humanhealth and environmental footprints, which directly or indirectly affects the population. The most common health problems among miners are malaria (36%) and abdominal pain (20%). The standard of living of the miners are evidently low, and most mines are characterized by schooldropouts, prostitutes and thieves. Mining sites have deplorably poor hygiene, with evident burning of amalgams to recover gold.Conclusion: ASGM have been accompanied by wanton mowing down of vegetation, landdegradation as well as mercuric pollution of water, air, land and aquatic ecosystems. It issuggested that the Ugandan government should re-enforce committees to follow up on ASGMactivities and train artisans on sustainable (non-mercury) alternative gold extraction methods thatdo not create new toxic exposures such as using borax, magnets and sluice boxes. Artisansshould take up farming actively as an alternative.

description: Matter collineations (MCs) are the vector fields along which the energy-momentum tensor remains invariant under the Lie transport. Invariance of the metric, the Ricci and the Riemann tensors have been studied extensively and the vectors along which these tensors remain invariant are called Killing vectors (KVs), Ricci collineations (RCs) and curvature collineations (CCs), respectively. In this paper plane symmetric static spacetimes have been studied for their MCs. Explicit form of MCs together with the Lie algebra admitted by them has been presented. Examples of spacetimes have been constructed for which MCs have been compared with their RCs and KVs. The comparison shows that neither of the sets of RCs and MCs contains the other, in general.

description: We introduce a concept of distance for a space-time where the notion of point is replaced by the notion of physical states e.g. probability distributions. We apply ideas of information theory and compute the Fisher information matrix on such a space-time. This matrix is the metric on that manifold. We apply these ideas to a simple model and show that the Lorentzian metric can be obtained if we assumed that the probability distributions describing space-time fluctuations have complex values. Such complex probability distributions appear in non-Hermitian quantum mechanics.

description: We consider the thermal conductivity, shear viscosity, and momentum relaxation rates in the nucleon cores of the neutron stars. We study how the choice of the nuclear interaction and the model for three-body forces may affect these transport coefficients calculated within the Brueckner-Hartree-Fock many-body nuclear theory. We find that at relatively large densities the model dependence of the results is substantial. In addition we provide the analytical approximations which allow to incorporate our results in practical simulations.

description: We describe the goals and first results of a Program for Imaging of the PERseus cluster of galaxies (PIPER). The first phase of the program builds on imaging of fields obtained with the Hubble Space Telescope (HST) ACS/WFC and WFC3/UVIS cameras. Our PIPER target fields with HST include major early-type galaxies including the active central giant NGC 1275; known Ultra-Diffuse Galaxies; and the Intracluster Medium. The resulting two-color photometry in F475W and F814W reaches deep enough to resolve and measure the globular cluster (GC) populations in the Perseus member galaxies. Here we present initial results for eight pairs of outer fields that confirm the presence of Intergalactic GCs (IGCs) in fields as distant as 740 kpc from the Perseus center (40\% of the virial radius of the cluster). Roughly 90% of these IGCs are identifiably blue (metal-poor) but there is a clear trace of a red (metal-rich) component as well, even at these very remote distances.

description: Pigmented ingredients of Kampala cookery recipes: beet root (Beta vulgaris), red onions (Allium cepa), red cabbage (Brassica oleracea var. capitata f. rubra), eggplant (Solanum melongena L.) and red dodo (Amaranthaceae) were screened for anthocyanins. Sliced 5.0±0.1g of leaves, soft parts and/or peelings of the samples were extracted with acidified methanol for 24 hours. Filtered extracts were concentrated to dryness and aqueous diluted 1ml of the extracts were analyzed by UV spectrophotometry. A scan from 200-600nm generated characteristic absorption spectra of each extract. Results showed that all the samples had anthocyanins except beetroot extract that had balantins with absorption peaks at 210, 220, 235, 255, 290, 480, 535 and 550nm. Red cabbage had maxima at 225, 240, 255, 290 and 555nm. The maximum absorbances of eggplant were observed at 210, 220, 245, 265 and 290nm while red dodo had maximum absorbances at 205, 215. 240, 250, 290 and 540nm. Red onions had absorbances at 220, 250, 270 and 290nm. Beet root is a rich nutritious source of balantins. Further research to identify and characterize the anthocyanins should be done.

description: Despite clear production, environmental and economic benefits associated with the adoption of controlled traffic farming (CTF), its use in vegetable production is often constrained by the lack of suitable harvest equipment. A possible solution to that constraint is the use of Wide Span (WS) tractors, which would provide a mechanisation platform on which a wide range of production machinery could be mounted. Such machines are not commercially available, but a prototype developed in Denmark in 2013, and more recent autonomous developments in Canada in 2017, are indicative of future possibilities. Building on earlier work, modelling was done to estimate the economic impact of adopting Mixed-WS CTF, in which a WS harvest platform is integrated with conventional tractors, and WS CTF, based on WS tractors alone. Returns were calculated as income minus operating and ownership costs (including interest and depreciation). As no commercial adoption of WS tractors has yet occurred, modelling was done using conservative estimates of costs and returns applied to case study farm scenarios. Modelling results indicated median increases in average returns of up to 59 per cent. The most important cost factors to be considered were machinery capital costs and the impacts on harvest efficiency under CTF, while on the benefit side of the equation, crop yields had the most influence on modelling results.

SPECIES CHARACTERISATION. — Relatively small, s inistral Neptunea species with flat whorl profile and shallow suture. Shell smooth or with low spiral cords separated by faint spiral grooves; thickened axial growthlines on the bigger specimens. Aperture elongate with an open siphonal canal. Juveniles are common in the studied material with a prominent protoconch.
DISTRIBUTION. — Lower Pleistocene: NSB, Norwich Crag and Weybourne Crag, England (Harmer 1918; Preece et al. 2020); Atlantic, Selsoif, NW France (Vervoenen et al. 2014). — Lower-Middle Pleistocene: Channel region, England (Vervoenen et al. 2014). — Middle Pleistocene: Irish Sea (Harmer 1918). — Pleistocene (indeterminate): Netherlands (Vervoenen et al. 2014).
REMARKS
Neptunea inversa Harmer, 1918 differs from N. contraria (Linnaeus, 1771) in being smaller, lower spired, with less convex whorls separated by a shallower suture. It is a marker species for early-middle Pleistocene assemblages of the southern North Sea Basin, Channel and Irish Sea (Vervoenen et al. 2014). Those authors noted than the specimen from Selsoif has slightly more convex whorls than usual for specimens of N. inversa from Early and Middle Pleistocene localities (not Late Pleistocene; lapsus). Adult specimens are uncommon in Selsoif where the species is represented by hundreds of juveniles. However, one of the specimens illustrated (Pl. 6, fig. 9) has a low spire and very flat whorls in keeping with the species.

description: The aim of this study was to analyse the survival rate of cracked teeth after endodontic treatment. The secondary aim was to compare the survival rate of cracked teeth restored with composite filling/crown and those restored with a full crown. The study was conducted retrospectively from three general dental clinics in Stockholm, which are all part of the national dental service organisation. Two-hundred patients with teeth receiving endodontic treatment due to symptomatic cracks were included. The patient data range from year 2001 to 2016. The mean age of the patients was 48 years (range 29–69). Fifty-five per cent had cracks located above the pulpal cavity, 11% within the pulpal cavity and 3% located in the root canal. The cracks were located most commonly on the proximal surfaces. The survival rate for teeth with cracks was 68% and 54% after 5 and 10 years, respectively. The survival rate was significantly higher (97%) for cracked teeth receiving a full crown after endodontic treatment compared to teeth restored with either a composite filling or composite crown. The overall survival rate for cracked teeth was 68% after 5 years, while it was significantly higher for cracked teeth restored with a full crown. The results suggest within the limitations of this study that cracked teeth should be restored with a full crown after endodontic treatment.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

We also find that there are portions of the initial parameters space for which no solution is admitted by the reduced equations. Whenever solutions do exist, their physical interpretation is examined through the behavior of Ricci and/or Kretsmann scalar, as well as with the identification of the effective energy momentum tensor in terms of a perfect fluid. There are cases in which no singularities appear and others where the effective fluid is isotropic.

description: We explore a novel method of describing the radiation friction of particles traveling through a mechanically resistive medium. We introduce a particle motion induced matter warping along the path in a manner assuring that charged particle dynamics occurs subject to radiative energy loss described by the Larmor formula. We compare our description with the Landau-Lifshitz-like model for the radiation friction and show that the established model exhibits non-physical behavior. Our approach predicts in the presence of large mechanical friction an upper limit on radiative energy loss being equal to the energy loss due to the mechanical medium resistance. We demonstrate that mechanical friction due to strong interactions, for example of quarks in quark-gluon plasma, can induce significant soft photon radiation.

description: Much of Sub-Saharan Africa is characterised by premature deindustrialisation. In this paper, it is argued that the difficulty experienced by this region with the expansion of manufacturing is related to the fact that most of these countries are land-abundant and thus there is a comparative advantage for agriculture. An agriculture-based model of development thus is most appropriate. The expansion of agricultural production can have both direct and indirect effects on the growth of output and employment in manufacturing. The Ethiopian experience is used to illustrate these ideas. Time-series analysis indicates that agriculture has indeed played a key role in the growth of manufacturing and services.

description: This continent-wide review of studies on price transmission implemented for the global, regional cross-border, within-country urban and within-country rural market segments provides a broad overview of current conditions in Sub-Saharan Africa food markets and provides insights into how market development varies across regions and crops. The review focuses on barriers to trade, both those related to policy and those related to general market development. Observations in the reviewed studies show that there are several long-run and short-run factors that have inhibited, and currently inhibit, food trade in the analysed markets. The long-run factors are related to general market development, such as imperfect substitutability between imported and domestic produce and infrastructure deficiencies. Short-run factors include intermittent changes in trade and/or tax policy and changes in self-sufficiency status. In only a few cases were no barriers to trade identified, and these were for highly traded foods between markets within countries. Since tradability is an indicator of market development, greater policymaker and donor partner attention is needed to remove barriers to trade, especially for foods that are efficiently produced domestically but do not yet have a welldeveloped domestic or international market.

description: This analysis sits against the backdrop of unsuccessful attempts to reindustrialise Africa. Zambia must diversify from copper dependency to agriculture and the agro-processing sectors, and the question is whether there is enough capacity to deliver jobs or growth. This paper studied the agroprocessing sector, where mean technical efficiency was 42.5% and mean scale efficiency was 81.7%. Beverage firms fared better than food producers and, within food production, meat processing did best, while baking and milling firms did the worst. There are benefits to centralisation and being large scale, although one in five firms was too large. A reindustrialisation programme should focus on the promotion of modern technologies, capacity building and infrastructure development, as well as on improvements in the regulatory framework.

description: The determination by powder neutron diffraction of the ambient temperature crystal structures of compounds in the NaxCoO2 family, for 0.3 < x <= 1.0, is reported. The structures consist of triangular CoO2 layers with Na ions distributed in intervening charge reservoir layers. The shapes of the CoO6 octahedra that make up the CoO2 layers are found to be critically dependent on the electron count and on the distribution of the Na ions in the intervening layers, where two types of Na sites are available. Correlation of the shapes of cobalt-oxygen octahedra, the Na ion positions, and the electronic phase diagram in NaxCoO2 is made, showing how structural and electronic degrees of freedom can be coupled in electrically conducting triangular lattice systems.

description: Organic farming is one of the fastest-growing branches of agriculture in Germany. The net increase in the number of hectares comes partly from the conversion of conventional farms, but also in part from the acreage expansion of existing organic farms. So far, empirical research has focused on analysing conversion to organic farming, and lately on reversion to conventional farming. However, changes in individual organic farm sizes have remained ignored by empirical researchers. Additionally, the occurrence and the extent of farm growth are largely dependent on the regional conditions of land market, farm structure and policy measures. Therefore, it remains unclear what other factors besides increasing demand for organic products might influence growth of organic farms. The main objective in this study is to determine whether organic farms are changing their scale of operation and, if so, which factors contribute to – or stagnate – farm growth and to what extent. To answer these questions we analyse growth in a unique panel dataset of 453 farms over the 1993-2005 period using the system generalised method of moments estimator (SGMM). The results reveal that all farms increase area by a maximum of 10 ha and large farms change farm size more frequently than smaller ones. Increases in organic area are influenced by subsidies for organic farming and intensity of livestock production. Farm growth measured in terms of output is affected by farm size, land, capital, soil quality, and intensity of livestock production.

description: In the framework of Lagrangian formulation, some q-deformed physical systems are considered. The q-deformed Legendre transformation is obtained for the free motion of a non-relativistic particle on a quantum line. This is subsequently exploited to obtain the Lagrangians for the q-deformed harmonic oscillator and q-deformed relativistic free particle. The Euler-Lagrange equations of motion are derived in a consistent manner with the corresponding Hamilton's equations. The Lagrangian for the q-deformed relativistic particle is endowed with the q-deformed gauge symmetry and reparametrization invariance which are shown to be equivalent only for $ q = \pm 1$.

description: Analyzing the ever-increasing volume of posts on social media sites such as Facebook and Twitter requires improved information processing methods for profiling authorship. Document classification is central to this task, but the performance of traditional supervised classifiers has degraded as the volume of social media has increased. This paper addresses this problem in the context of gender detection through ensemble classification that employs multi-model deep learning architectures to generate specialized understanding from different feature spaces.
Shape fluctuations and optical transition of He$_{2}^{*}$ excimer tracers in superfluid $^4$He

description: Metastable He$_{2}^{*}$ excimer molecules have been utilized as tracer particles of the normal component in superfluid $^4$He (He II) which can be imaged via laser-induced fluorescence. These excimer molecules form tiny bubbles in He II and can bind to quantized vortices at sufficiently low temperatures, thereby allowing for direct visualization of vortex dynamics in an inviscid superfluid. However, the $a^{3}Σ^+_{u}$${\rightarrow}$$c^{3}Σ^+_{g}$ optical absorption line, which is responsible for the fluorescence imaging of the He$_{2}^{*}$ molecules, is controlled by fluctuations on the bubble shape, and its exact line profile is not known at low temperatures. In this paper, we present a bubble model for evaluating the surface fluctuation eigenmodes of the excimers in He II. The line profile of the $a^{3}Σ^+_{u}{\rightarrow}c^{3}Σ^+_{g}$ transition is calculated at different temperatures by considering both the zero-point and thermal fluctuations on the bubble shape. We show that, as the temperature drops from 2~K to 20 mK, the peak absorption strength is enhanced by a factor of about five, accompanying a blueshift of the peak location by about 2 nm. A double-peak line profile due to the rotational levels of the molecular core can be resolved. This bubble model also allows us to evaluate the stiffness of the He$_{2}^{*}$ bubbles and hence their diffusion constant in He II due to scattering off thermal phonons. Our results will aid the design of future experiments on imaging quantized vortices in He II using He$_{2}^{*}$ tracers.

description: We present a simple superfield Lagrangian for massive supergravity. It comprises the minimal supergravity Lagrangian with interactions as well as mass terms for the metric superfield and the chiral compensator. This is the natural generalization of the Fierz-Pauli Lagrangian for massive gravity which comprises mass terms for the metric and its trace. We show that the on-shell bosonic and fermionic fields are degenerate and have the appropriate spins: 2, 3/2, 3/2 and 1. We then study this interacting Lagrangian using goldstone superfields. We find that a chiral multiplet of goldstones gets a kinetic term through mixing, just as the scalar goldstone does in the non-supersymmetric case. This produces Planck scale (Mpl) interactions with matter and all the discontinuities and unitarity bounds associated with massive gravity. In particular, the scale of strong coupling is (Mpl m^4)^1/5, where m is the multiplet's mass. Next, we consider applications of massive supergravity to deconstruction. We estimate various quantum effects which generate non-local operators in theory space. As an example, we show that the single massive supergravity multiplet in a 2-site model can serve the function of an extra dimension in anomaly mediation.

description: For the visualization and analysis of the stress field from 3D thermo-hydro-mechanical (THM) numerical model results two main technical steps are necessary. First, one has to derive from the six independent components of the 3D stress tensor scalar and vector values such as the orientation and magnitude of the maximum and minimum horizontal stress, stress ratios, or the differential stress. It is also of great interest to display e.g. the normal and shear stress with respect to an arbitrarily given surface. Second, an appropriate geometry should be given such as cross sections, profile e.g. for borehole pathways or surfaces on which the model results and further derived values are interpolated. This includes also the three field variables temperature, pore pressure and the displacement vector. To facilitate and automate these steps the Add-on GeoStress for the professional visualization software Tecplot 360 EX has been programmed. Besides the aforementioned values derived from the stress tensor the tool also allows to calculate the values of Coulomb Failure Stress (CFS), Slip and Dilation tendency (ST and DT) and Fracture Potential (FP). GeoStress also estimates kinematic variables such as horizontal slip, dip slip, rake vector of faults that are implemented as contact surfaces in the geomechanical-numerical model as well as the true vertical depth (TVD). Furthermore, the Add-on can import surface and polyline geometries and interpolates on these all available stress parameter. This technical report describes the visualization tool with examples using 3D geomechanical-numerical model results from the finite element software Abaqus v2019. It also presents a number of special features of Tecplot 360 EX in combination with GeoStress that allow a professional and efficient analysis. We also address now the usage GeoStress with PyTecplot which is a powerful tool to automize the analysis. The Add-on as well as the example and input files used in this manual is published by Stromeyer et al. (2020) and the table below gives an overview of the files with a short explanation as they appear in the manual.

description: The organic market depends on an effective and efficient certification system. Control bodies or authorities are pivotal to this system. From a social point of view, our objective is to theoretically optimize inspection strategies. For this, sanctions and inspection frequencies have to be implemented in a way that the net social damage arising from farmers’ non-compliance with an organic standard will be minimized. In scenarios that combine different kinds of social damages, fines and compliance cost distributions for an assumed set of farms we use Monte Carlo simulations to model farmers’ non-compliance and resulting social damages. Depending on potential reputation losses and com-pliance cost variability among farms we identify different adequate control frequencies.
