Abstract:
AbstractWild mustard (Sinapis arvensis L.) is a widespread weed of the southeastern cropping region of Australia. Seed germination ecology of S. arvensis populations selected from different climatic regions may differ due to adaptative traits. Experiments were conducted to evaluate the effects of temperature, light, radiant heat, soil moisture, salt concentration, and burial depth on seed germination and seedling emergence of two populations (Queensland [Qld] population: tropical region; and Victoria [Vic] population: temperate region) of S. arvensis. Both populations germinated over a wide range of day/night (12-h/12-h) temperatures (15/5 to 35/25 C), and had the highest germination at 30/20 C. Under complete darkness, the Qld population (61%) had higher germination than the Vic population (21%); however, under the light/dark regime, both populations had similar germination (78% to 86%). At 100 C pretreatment for 5 min, the Qld population (44%) had higher germination than the Vic population (13%). Germination of both populations was nil when given pretreatment at 150 and 200 C. The Vic population was found tolerant to high osmotic and salt stress compared with the Qld population. At an osmotic potential of −0.4 MPa, germination of Qld and Vic populations was reduced by 85% and 42%, respectively, compared with their respective controls. At 40, 80, and 160 mM sodium chloride, germination was lower for the Qld population than the Vic population. Averaged over the populations, seedling emergence was highest (52%) from a burial depth of 1 cm and was nil from 8-cm depth. Differential germination behaviors of both populations to temperature, light, radiant heat, water stress, and salt stress suggest that populations of S. arvensis may have undergone differential adaptation. Knowledge gained from this study will assist in developing suitable control measures for this weed species to reduce the soil seedbank.

Abstract. This paper investigates the ability of the VIC-2L model coupled to a routing model to reproduce streamflow in the catchment of the lower Elbe River, Germany. The VIC-2L model, a hydrologically-based land surface scheme (LSS) which has been tested extensively in the Project for Intercomparison of Land-surface Parameterization Schemes (PILPS), is put up on the rotated grid of 1/6 degree of the atmospheric regional scale model (REMO) used in the Baltic Sea Experiment (BALTEX). For a 10 year period, the VIC-2L model is forced in daily time steps with measured daily means of precipitation, air temperature, pressure, wind speed, air humidity and daily sunshine duration. VIC-2L model output of surface runoff and baseflow is used as input for the routing model, which transforms modelled runoff into streamflow, which is compared to measured streamflow at selected gauge stations. The water balance of the basin is investigated and the model results on daily, monthly and annual time scales are discussed. Discrepancies appear in time periods where snow and ice processes are important. Extreme flood events are analyzed in more dital. The influence of calibration with respect to runoff is examined.

Abstract:
This essay explores the intersection between the politics of regionalism and recreation in Anthony Trollope's Barsetshire novels. The relationship between narrative structure and local environment articulated in Trollope's series links the form of the Victorian regional novel to an interrogation of England's relationship to its internal geography by questioning, in effect, how a region can remain autonomous and yet be a resource for national identity. Trollope's response is to use the regional practice of fox-hunting to preserve the West Country's unique place in the national imagination through sport. Situating the Barsetshire novels within hunting's vexed place in nineteenth-century rural communities and focusing on Doctor Thorne, I suggest that Trollope advances a conservative ideology that the region's identity can only be sustained through preserving country house culture. Trollope represents hunting as an ingrained rural custom, thus paradoxically using a national sport to promote regional insularity and justify the landowning class' social control of the region.

Abstract. The Tropical Rainfall Measuring Mission (TRMM) carries aboard the Precipitation Radar (TRMMPR) that measures the backscatter (σ°) of the surface. σ° is sensitive to surface soil moisture and vegetation conditions. Due to sparse vegetation in arid and semi-arid regions, TRMMPR σ° primarily depends on the soil water content. In this study we relate TRMMPR σ° measurements to soil water content (ms) in Lower Colorado River Basin (LCRB). σ° dependence on ms is studied for different vegetation greenness values determined through Normalized Difference Vegetation Index (NDVI). A new model of σ° that couples incidence angle, ms, and NDVI is used to derive parameters and retrieve soil water content. The calibration and validation of this model are performed using simulated and measured ms data. Simulated ms is estimated using Variable Infiltration Capacity (VIC) model whereas measured ms is acquired from ground measuring stations in Walnut Gulch Experimental Watershed (WGEW). σ° model is calibrated using VIC and WGEW ms data during 1998 and the calibrated model is used to derive ms during later years. The temporal trends of derived ms are consistent with VIC and WGEW ms data with correlation coefficient (R) of 0.89 and 0.74, respectively. Derived ms is also consistent with the measured precipitation data with R=0.76. The gridded VIC data is used to calibrate the model at each grid point in LCRB and spatial maps of the model parameters are prepared. The model parameters are spatially coherent with the general regional topography in LCRB. TRMMPR σ° derived soil moisture maps during May (dry) and August (wet) 1999 are spatially similar to VIC estimates with correlation 0.67 and 0.76, respectively. This research provides new insights into Ku-band σ° dependence on soil water content in the arid regions.

Abstract:
Hydrological process simulation and rainfall–runoff analysis are important foundations for reasonably evaluating changes in water resources. In this paper, the VIC (Variable Infiltration Capacity) hydrological model was used to simulate runoff without observed data for exploring the applicability of the model in the Kequ, Dari, and Jimai river basins in the source region of the Yellow River, and the Balegen River basin in the inland arid source region. The results show that, from 2015 to 2018, the VIC model had a good simulation effect. The Nash efficiency coefficients (NSE) of the four basins were all above 0.7, and the NSE of the Dari River basin reached 0.93. The relative error (RE) of the three river basins was about 5%, on average, and the RE of the Balegen basin was 6.50%, indicating that the model has good applicability in the study area. Climate perturbation experiments were performed to quantitatively analyze the relationship between rainfall and runoff. The results show that, in the source area of the Yellow River, rainfall and runoff are roughly linearly related. However, in the inland arid source area, temperature has a slightly greater impact on runoff than rainfall.

Abstract:
Snowmelt water is essential to the water resources management over the Three-River Headwater Region (TRHR), where hydrological processes are influenced by snowmelt runoff and sensitive to climate change. The objectives of this study were to analyse the contribution of snowmelt water to the total streamflow (fQ,snow) in the TRHR by applying a snowmelt tracking algorithm and Variable Infiltration Capacity (VIC) model. The ratio of snowfall to precipitation, and the variation of the April 1 snow water equivalent (SWE) associated with fQ,snow, were identified to analyse the role of snowpack in the hydrological cycle. Prior to the simulation, the VIC model was validated based on the observed streamflow data to recognize its adequacy in the region. In order to improve the VIC model in snow hydrology simulation, Advanced Scanning Microwave Radiometer E (ASMR-E) SWE product data was used to compare with VIC output SWE to adjust the snow parameters. From 1971 to 2007, the averaged fQ,snow was 19.9% with a significant decreasing trend over entire TRHR (p < 0.05).The influence factor resulted in the rate of change in fQ,snow which were different for each sub-basin TRHR. The decreasing rate of fQ,snow was highest of 0.24%/year for S_Lantsang, which should be due to the increasing streamflow and the decreasing snowmelt water. For the S_Yangtze, the increasing streamflow contributed more than the stable change of snowmelt water to the decreasing fQ,snow with a rate of 0.1%/year. The April 1 SWE with the minimum value appearing after 2000 and the decreased ratio of snowfall to precipitation during the study period, suggested the snow solid water resource over the TRHR was shrinking. Our results imply that the role of snow in the snow-hydrological regime is weakening in the TRHR in terms of water supplement and runoff regulation due to the decreased fQ,snow and snowfall.

Abstract:
Abstract Distributive mixing performance in Variable Intermeshing Clearance (VIC) mixers was studied numerically and verified experimentally. A fluid dynamics analysis package (FIDAP), based on the finite element method, was employed to simulate the flow patterns in the original lab size mixer (VIC1) and a new design with an enlarged mixing chamber (VIC2). Distributive mixing was studied numerically by means of tracking the evolution of particles originally gathered as clusters. The results of numerical simulations were checked against experimental data to verify the validity of the model. Both the numerical simulations and the experimental data indicate that the VIC2 design, with an enlarged mixing chamber, shows consistently better distributive mixing results in comparison with the traditional VIC1. In both mixers, increasing the inter-rotor clearance improves distributive mixing. However, enlarging the gap size too much in the bridge region, in the VIC2 mixer, becomes detrimental for mixing. The initial position of the clusters is also important in distributive mixing. Clusters located in the middle of the bridge region are better distributed than the ones located on the sides, particularly at small inter-rotor clearances.

Abstract:
An agricultural drought assessment is the basis for formulating agricultural drought mitigation strategies. Traditional agricultural drought assessment methods reflect agricultural drought degree by using the soil water deficit, e.g., Soil Moisture Anomaly Percentage Index (SMAPI). However, due to varying water demands for different crops, a given soil water deficit results in varying crop water deficits and agricultural droughts. This variation often leads to a misinterpretation of agricultural drought classification when one only considers the soil water deficit. To consider the influence of crop growth, this study proposes an agricultural drought assessment method by coupling hydrological and crop models (variable infiltration capacity-environmental policy integrated climate, VIC-EPIC). Agricultural drought in Jiangsu Province, China was evaluated using the VIC-EPIC model and crop water anomaly percentage index (CWAPI). The validation results based on the actual drought records showed that the correlation coefficients (0.79 and 0.82, respectively) of the statistical values and CWAPI simulated values of light and moderate drought area rates were greater than those for SMAPI (0.72 and 0.81, respectively), indicating that the simulation results of the VIC-EPIC model in Jiangsu Province were highly reasonable. The temporal and spatial variation characteristics of the drought grade in typical large-scale drought events in Jiangsu Province were also analyzed.

Abstract:
Depicted in the mid to late nineteenth-century periodical press as wild, remote, and ‘intensely national’, Wales was perceived as a place of quiet mystery, geographically and socially distinct from the industrialisation of Victorian England. The borderland territory of the Wye Valley – what the Victorian journalist and historian, Barbara Hutton, called ‘Wye-Land’ – has been inhabited for over 12,000 years and preserves an ancient British identity in its rich archaeological landscapes. Developments in mid Victorian archaeology and anthropology precipitated a rise in the number of prehistoric excavations, which popularised knowledge of how ancient Britons lived and died. Drawing from articles in the late Victorian periodical press, and the activities of the Cardiff Naturalist's Society in the 1870s, which included the study of geology, botany and archaeology, this paper suggests that the observation of natural phenomena in the late nineteenth century was closely associated with the study of past human societies. I identify the changing interpretations of prehistoric sites – from early Victorian notions of barbarous druids, to more informed and sensitive appreciations of ancient British societies, whose sympathetic relation to the landscape fostered imaginative connections between late Victorians and their ancestors. This transition away from perceptions of being wholly distinct from prehistoric activity, shaped late Victorian pastoral journalism and encouraged a more integrated vision of the relationship between past and present human activity in the region.

Abstract:
During the nineteenth century, defence was a major issue in Victoria and Australia, as indeed it was in other British colonies and the United Kingdom. Considerable pressure was brought to bear by London on the self-governing colonies to help provide for their own defence against internal unrest and also possible invasions or incursions by nations such as France, Russia and the United States.
From 1851 until defence was handed over to the new Australian Commonwealth at Federation in 1901, the Victorian colonial government spent considerable energy and money fortifying parts of Port Phillip Bay and the western coastline as well as developing the first colonial navy within the British Empire. Citizens were invited to form volunteer corps in their local areas as a second tier of defence behind the Imperial troops stationed in Victoria. When the garrison of Imperial troops was withdrawn in 1870, these units of amateur citizen soldiers formed the basis of the colony’s defence force. Following years of indecision, ineptitude and ad hoc defence planning that had left the colony virtually defenceless, in 1883 Victoria finally adopted a professional approach to defending the colony. The new scheme of defence allowed for a complete re-organisation of not only the colony’s existing naval and military forces, but also the command structure and supporting services. For the first time an integrated defence scheme was established that co-ordinated the fixed defences (forts, batteries minefields) with the land and naval forces. Other original and unique aspects of the scheme included the appointment of the first Minister of Defence in the Australian colonies and the first colonial Council of Defence to oversee the joint defence program. All of this was achieved under the guidance of Imperial advisors who sought to integrate the colony’s defences into the wider Imperial context.
This thesis seeks to analyse Victoria’s colonial defence scheme on a number of levels – firstly, the nature of the final defence scheme that was finally adopted in 1883 after years of vacillation, secondly, the effectiveness of the scheme in defending Victoria, thirdly, how the scheme linked to the greater Australasian and Imperial defence, and finally the political, economic, social and technological factors that shaped defence in Victoria during the second half of the nineteenth century.

Abstract and summary

The glocal province of competence.

The regional building up of knowledge at Växjö University and its choice of home region.

The aim of the study is to give views on knowledge and to describe and discuss which home region Växjö University has chosen as its context. Taking my point of departure in the literature and in examples, I illustrate, discuss and examine how three different disciplines at the university have chosen their home regions. The disciplines are history, economics and biology. The study covers the last 33 years.

The empirical study, with its focus only on regional matters, is based on four sources. 1. Research and researchers 2. Education and the impact it has as shown by the papers written by students at bachelor and master levels. In all 459 papers have been classified 3. Interviews with the professors 4. The University’s annual report given by the board of directors.

The study centres on the diverse and complex characteristics of regions which leads to a variation of regions used by different actors at the university. One aspect is the consideration of the relationship between formal and everyday knowledge.

The three disciplines have different attitudes towards home region and towards how it is constituted. Generally speaking, historians see the home region more as territory with the emphasis on the southern part of the province of Småland. The economists concentrate on home region as a functional arena, even though examples and studies sometimes are found in Småland. The biologists, who are in a new discipline at the university, sometimes study the southern part of Sweden, but focus on general aspects. All three of them are interested in interdisciplinary methods and studies in order to build up knowledge connected to the home region. The board of directors has not chosen one specific region and varies its attitudes over the years.

The interviews gave a broad perspective on knowledge and regions and with views on a local and global world. A glocal region.

Abstract:

The first part of this thesis describes a synthetic strategythat provides all eight possible isomers of a given vic-aminoalcohol starting from vinylepoxides. The value of a generalroute is evident, as several isomers are needed ininvestigations of structure-activity relationships forpharmacologically active derivatives, and for optimizing theperformance of chiral ligands containing the amino alcoholmoiety.

Vinylepoxides, obtained in high enantiomeric excess, werering-opened both with inversion and retention ofstereochemistry, delivering two diastereomeric amino alcoholswith high regio- and stereoselectivity. Via ring-closure toaziridines and subsequent regioselective ring-opening withsuitable oxygen nucleophiles, the two remaining amino alcoholswere selectively achieved.

Within this study, two efficient protocols for theregioselective and stereospecific aminolysis of vinylepoxideshave been presented. Comparedto previous methods, theseprocedures use milder reaction conditions, shorter reactiontimes, generally give higher yields and are applicable to alarger set of substrates. Furthermore, the ring-closure ofvic-amino alcohols to the corresponding N-H vinylaziridines hasbeen investigated. Three routes have been found useful, whichone is preferred depends on substrate and scale.

In the second part of the thesis, the synthetic strategy isapplied on the synthesis of Sphingosine and its regio- andstereoisomers. Moreover, a rapid way of determining relativeconfiguration of vic-amino alcohols is described, which shouldbe of substantial use when amino alcohols are formed bydiastereoselective reactions.

Full text
Abstract:
The Notch receptor is part of a highly conserved omnipresent developmental pathway that has crucial roles in developing and self-renewing tissues. During activation of the signalling pathway Notch binds to its ligand, presented on a neighbouring cell. It is thought that this results in a conformational change within the Negative Regulatory Region (NRR) unmasking a key proteolytic site (S2) and allows for metalloprotease cleavage. This facilitates further cleavage by gamma-secretase, initiating downstream events. Thus far, the molecular mechanism by which the S2 site is revealed has not been defined, though indirect evidence favours a model whereby transendocytosis of the Notch extracellular domain into the ligand bearing cell results in mechanical unfolding of the NRR. Research presented here suggests the NRR of human Notch2 (hN2) unfolds within a mechanosensing force range. Furthermore, through the application of a force (200 pN) the hN2-NRR was shown to unfold sufficiently to expose the S2 site allowing cleavage by metalloproteases. Molecular dynamics (MD) simulations offer insight into the unfolding process of the hN2-NRR, revealing near-sequential unfolding of its constituent LNR and HD domains. Removing the linker region between LNR’s A and B appears to be the first force ‘barrier’ in the unfolding pathway, producing the largest increase in solvent accessibility at the S2 cleavage site. Through docking simulations, this unfolding event was shown to expose the S2 cleavage site sufficiently to allow access to the metalloprotease TACE. Removing coordinated metal ions from the hN2-NRR structure resulted in a dramatic decrease in the forces required for unfolding during AFM experiments, highlighting their role in increasing the resistance of the hN2-NRR to forced unfolding. Removal of disulphide bonds within the structure resulted in a loss of detectable LNR unfolding, highlighting their role in LNR stabilisation.Six HD destabilising mutants, characterised through their role in the hN1 disease, T-cell Acute Lymphoblastic Leukemia, showed three key changes to the unfolding pathway of the hN2-NRR. Firstly, mutants A1647P, L1573P and V1623D showed a dramatic decrease in force required for unfolding in AFM experiments. MD simulations highlighted a lack of force required for the unfolding the LNRA:B linker previously characterised as the key event in removing NRR autoinhibition. Secondly, all the mutants studied here showed changes to the stability of the alpha3-helix (within the HD domain) resulting in transient shifts or bending during unfolding of the LNRA:B linker and the LNRB. Finally, changes were observed within the LNRC of A1647P and L1566P. Within these mutants the LNRC was observed to be unfolding, an event not present during wild-type unfolding. Within mutant L1566P this is thought to be due to the disruption of the conserved salt-bridge occurring between Arg1567 (HD domain) and Asp1506 (LNRC). Within mutant A1647P this is likely due to widespread domain destabilisation. Overall, research presented here has provided the first direct evidence that the NRR is mechanosensing and that mechanical force can allow for cleavage at the S2 site. Further characterisation has been performed to analyse the unfolding pathway through ion chelation, disulphide oxidation and mutagenesis studies.

El Plan Estratégico Agregado para la macro región siete, que está conformada por los departamentos de Ayacucho, Huancavelica e Ica, se ha realizado tomando en cuenta el modelo secuencial del Proceso Estratégico hecho por el Dr. Fernando D´Alessio, donde se plantean las estrategias que permitirán el crecimiento sostenible de los sectores económicos de la macro región, utilizando de manera eficiente los recursos naturales y planteando nuevas actividades económicas que permitirá el desarrollo socio-económico de su población, para ello se realizó un análisis de su situación actual, en la cual se determinó las fortalezas y debilidades así como sus oportunidades y amenazas. La macro región siete cuenta con las tres regiones naturales del país, lo que le otorga una ventaja comparativa con respecto a otras macro regiones y será explotada respetando la sostenibilidad de los recursos. Así, en el análisis elaborado, se está planteando el desarrollo del primer circuito turístico que integre a toda la macro región, para ello se incentivará el turismo vivencial y eco turismo, que permitirá a los pobladores de las zonas de influencia obtener ingresos por los servicios prestados a los visitantes. El Plan Estratégico de la macro región siete se basa en cuatro pilares fundamentales que permitirán su desarrollo y crecimiento, estos son: (a) la educación, su posición competitiva está ligeramente debajo del promedio nacional pero es muy factible de revertir a mediano plazo, (b) el turismo, para potenciarlo se mejoraran las redes viales de conexión, con la ayuda del sector privado, obras por impuestos, etc., (c) la agro exportación, que se potenciará con la reducción de costos logísticos, y (d) la utilización de energías renovables, para ello los objetivos de largo plazo planteados permitirán elevar la competitividad de la macro región siete convirtiéndola en el referente del país
The Added Strategic Plan for the seven macro region, which is made up of the departments of Ayacucho, Huancavelica and Ica, has been made taking into account the sequential model of the Strategic Process by Dr. Fernando D'Alessio, where strategies arise that will enable sustainable growth of economic sectors of the macro region, efficiently using natural resources and raising new economic activities that will enable the socio-economic development of its people, to do an analysis of their current situation was conducted in which the strengths and weaknesses as well as its opportunities and threats was determined. The seven macro region has three natural regions of the country, which gives it a comparative advantage over other macro regions and will be exploited respecting the sustainability of resources. Thus, in the analysis prepared, it is considering the development of the first tourist circuit that integrates the entire macro region, for which the experiential tourism and ecotourism, which will allow the inhabitants of the areas of influence monetizing services will be encouraged provided to visitors. The Strategic Plan of the seven macro region is based on four pillars that allow development and growth, these are: (a) education, its competitive position is slightly below the national average but is very likely to reverse in the medium term, ( b) tourism, to enhance it road networks connecting improve, with the help of the private sector, tax works, etc., (c) agro export, which will be enhanced by reducing logistics costs, and (d) the use of renewable energies, for this long-term goals raised, will enable increase the competitiveness of the seven macro region making it the benchmark in the country

Geóloga
Chile es un país que destaca por su vitivinicultura a nivel mundial, sin embargo, esta actividad sigue prácticas tradicionales, donde la relación de la geología con la formación de los suelos y cómo esta interacción afecta al desarrollo de la vid es aún poco comprendida. Es en este contexto, que esta memoria tiene por objetivo realizar una caracterización geo-vitivinícola de Chile para efectos de le generación de criterios geológico y geomorfológicos de evaluación de zonas de cultivo de la vid. En virtud de este objetivo se realizó un mapa, escala 1:1.000.000 utilizando la geología generada por el SERNAGEOMIN (2004). Para acotar la zona de estudio, se definieron 17 valles vitivinícolas establecidos en el Decreto N°464, el cual determina las denominaciones de origen chilenas, a los cuales se les añadió la componente geológica mediante la incorporación de cuencas hidrográficas proporcionadas por la Dirección General de Aguas (DGA). Los valles se encuentran divididos en las regiones vinícolas de Atacama, Coquimbo, Aconcagua, del Valle Central, Sur y Austral. Para cada una de estas regiones y sus respectivos valles se describió la geología a escala regional y se caracterizaron las morfoestructural de Cordillera Principal, Depresión Central y Cordillera de la Costa. Además, a modo de explorar la incorporación de información de mayor detalle, se selecciona el Valle de Casablanca para realizar un mapeo escala 1:100.000 en base a la carta de la zona Valparaíso-Curacaví, con el fin de diferenciar los distintos tipos de depósitos y sus geomorfologías y también se estudió la variación del nivel estático, en un periodo de 10 años, para 28 pozos ubicados en este valle. Por su parte, en el Valle de Copiapó se realizó un mapeo de arcillas mediante imágenes satelitales ASTER para reconocer la distribución de los minerales illita, caolinita, montmorillonita y vermiculita. Por último, para seis valles definidos como prioritarios (Casablanca, Maipo, Rapel, Maule, Curicó e Itata) se realizaron mapas de aspecto y pendientes. Los valles se caracterizan por presentar variaciones norte-sur y este-oeste de las unidades geológicas y las unidades morfoestructurales y si bien valles de la misma región vitivinícola tienen características similares entre sí, cada uno de estos presenta particularidades únicas que los diferencian. Para Casablanca se pudo apreciar que el mayor detalle en la geomorfología permite diferenciar cuatro unidades geomorfológicas, que en el mapa de escala 1:1.000.000 corresponde a una. En cuanto al nivel estático es posible apreciar una clara disminución de este a lo largo de los años y en el Valle de Copiapó es posible reconocer las arcillas illita y caolinita. En base a las cuencas hidrográficas y las características geomorfológicas, se proponen posibles tres valles vitivinícolas en la Región de Aysén supeditados a las condiciones mesoclimáticas de ellos. Cada uno de estos presentan unidades de roca particulares, los cuales pueden representar interesantes terroirs en un escenario de cambio climático. Es así como la comprensión de las características geológicas enfocada a los valles vitivinícolas chilenos, podrá permitir la generación de criterios de evaluación de predios agrícolas.

Abstract:
La generació d’anticossos àmpliament neutralitzants contra el VIH-1 es el principal objectiu d’una vacuna que sigui capaç de controlar l’epidèmia causada per aquest virus. La glicoproteïna de l’embolcall del VIH-1 es l’únic antigen viral exposat a la membrana del virus y la principal diana de respostes humorals protectores. Dins d’aquesta proteïna han sigut identificades regions funcionals reconegudes per anticossos àmpliament neutralitzants, fent possible la definició de punts de vulnerabilitat del virus, cap als que una vacuna hauria de dirigir-se. En aquest context, la regió externa pròxima a la membrana (MPER) de la gp41 es un dels llocs de vulnerabilitat més representatius del virus, ja que està altament conservat, té un paper crucial per a la infectivitat del virus i es reconegut per anticossos protectors àmpliament neutralitzants. Tot i així, la seva situació, prop a la membrana, fa que el MPER sigui un domini poc accessible, exposat de manera transitòria, hidrofòbic i altament influenciat pels lípids de la membrana. Per tant, la seva immunogenicitat presenta una alta complexitat que ha de ser explorada en major profunditat. En aquesta tesi, aportem nou coneixement sobre l’immunogenicitat del MPER durant l´infecció natural i en models animals d’immunització. S’han avaluat miniproteïnes derivades de la gp41 que sobreexposen el MPER, per ser utilitzades com 1) nous plataformes per a la detecció d’anticossos anti-MPER i 2) prototipus d’immunògens presentats en proteoliposomes de diversa composició. Els resultats van revelar una alta immunogenicitat del MPER en humans, que correlaciona amb la resposta global contra la proteïna de l’embolcall, suggerint que el sistema immune no té cap restricció per a la generació d’aquest tipus d’anticossos. Tot i així, els anticossos detectats van mostrar una funcionalitat heterogènia, tant pel que fa a la capacitat neutralitzant com a la competició per diferents epítops, independentment de l’especificitat per MPER. A més, aquest resultats van ser reproduïts en animals immunitzats. En aquest últims, s’ha aconseguit generar un alt títol d’anticossos específics, que van ser potenciats per la incorporació als proteoliposomes de lípids complexes que mimetitzaven als de la partícula viral. Sorprenentment, es va generar una resposta immunodominant no neutralitzant contra un epítop solapant amb el de l’anticòs neutralitzant 2F5. En resum, la resposta humoral contra el MPER a humans i animals immunitzats no va correlacionar amb la capacitat neutralizant d’aquests i els anticossos generats són principalment no neutralitzants. Aquests resultats suggereixen que el balanç de la resposta neutralitzant i no neutralitzant té una important rellevància en la resposta global contra el MPER. Conseqüentment, sembla necessari un major refinament d’immunògens capaços d’evitar respostes no neutralitzants. Aquest redisseny es veurà altament beneficiat pel coneixement generat a partir de nous anticossos monoclonals contra el MPER que recullin l’heterogeneïtat funcional observada als nostres estudis.
La generación de anticuerpos ampliamente neutralizantes contra el VIH-1 es el principal objetivo de una vacuna que sea capaz de controlar la epidemia causada por el virus. La glicoproteína de la envuelta del VIH-1 es el único antígeno viral expuesto en la membrana del virus y la principal diana de respuestas humorales protectoras. Dentro de esta proteína se han identificado regiones funcionales que son reconocidas por anticuerpos ampliamente neutralizantes, lo cual ha permitido establecer puntos de vulnerabilidad del virus hacia los que una vacuna debería dirigirse. En este contexto, la región externa próxima a la membrana (MPER) de gp41 es uno de los sitios de vulnerabilidad del virus más representativos, ya que está altamente conservado, juega un papel crucial en la infectividad del virus y es reconocido por anticuerpos protectores ampliamente neutralizantes. Sin embargo, su localización, contigua a la membrana, hace del MPER un dominio poco accesible, expuesto de forma transitoria, hidrofóbico y altamente influenciado por lípidos de membrana. En consecuencia, su inmunogenicidad presenta una alta complejidad que debe ser explorada en mayor profundidad. En esta tesis, aportamos nuevo conocimiento sobre la inmunogenicidad del MPER a nivel de la infección natural y en modelos animales de inmunización. Hemos evaluado miniproteínas basadas en gp41 que sobreexponen el MPER, para ser utilizadas como 1) nuevas plataformas para la detección de anticuerpos anti-MPER y 2) prototipos de inmunógenos presentados en proteoliposomas de diversa composición. Los resultados han revelado una alta inmunogenicidad del MPER en humanos, que correlaciona con la respuesta global contra la proteína de la envuelta. Esto sugiere que el sistema inmune no tiene una especial restricción para la generación de este tipo de anticuerpos. Sin embargo, los anticuerpos detectados mostraron una funcionalidad heterogénea, en términos de capacidad neutralizante y competición por diferentes epítopos, independientemente de la especificidad por el MPER. Además, los resultados fueron reproducidos en animales inmunizados. En estos últimos, conseguimos generar un alto título de anticuerpos específicos, potenciados por la incorporación en los proteoliposomas de mezclas lipídicas complejas que mimetizaban las de la partícula viral. Sorprendentemente, se generó una respuesta inmunodominante no neutralizante que solapaba con un epítopo reconocido por el anticuerpo neutralizante 2F5. En resumen, la repuesta humoral natural contra el MPER en pacientes infectados por el VIH-1 y la generada en modelos animales mediante inmunización comparten ciertas características como son la especificidad y la escasa capacidad neutralizante. Estos resultados sugieren que el balance entre la respuesta neutralizante y no neutralizante podría tener una importante relevancia en la respuesta global contra el MPER. De este modo, es necesario un mayor refinamiento de inmunógenos que sean capaces de sortear respuestas no neutralizantes. Este rediseño se verá altamente beneficiado del conocimiento generado a partir de nuevos anticuerpos monoclonales contra el MPER que reflejen la heterogeneidad funcional observada en nuestros estudios.
The elicitation of broadly neutralizing antibodies (bNAbs) against HIV-1 constitutes the major goal of an effective vaccine able to control the epidemic caused by this virus. The HIV-1 envelope glycoprotein is the only viral antigen exposed on the surface of the virus and the main target of protective humoral responses. The identification within this protein of functional regions recognized by bNAbs has delineated an HIV-1 vulnerability map that has guided efforts for rational immunogen design. In this regard, the gp41 Membrane Proximal External Region (MPER) is a major HIV-1 vulnerability site because is highly conserved, plays a major role in viral infectivity and is targeted by protective bNAbs. However, its localization, next to the viral membrane, results in a hardly accessible, transiently exposed and hydrophobic domain, strongly influenced by membrane lipids. Therefore, the immunogenicity of the MPER offers a high level of complexity that needs to be further explored. In this thesis we provide new knowledge on the MPER immunogenicity in both natural HIV-1 infection and immunization in animal models. We generated gp41-based miniproteins which properly exposed the MPER region that have been used 1) as novel platforms for MPER antibody detection and 2) as immunogen candidates presented in different proteoliposome compositions. In humans, the results revealed a strong immunogenicity of the MPER that correlated with a global response against the envelope glycoprotein suggesting no special constraints for the immune system to target this region. However, the antibodies elicited showed heterogeneous functionality in terms of neutralizing capacity and epitope competition, regardless MPER specificity. Interestingly, these results were reproduced by immunization in animal models. High antibody titers were achieved that were specially enhanced by the addition of lipid mixtures mimicking the viral membrane. Interestingly, a non-neutralizing immunodominant response against an epitope that overlapped the 2F5 neutralizing antibody binding motif was identified. Overall, the anti-MPER response in both humans and animal model settings was not correlated with the neutralizing capacity and antibodies detected or induced by immunization were preferentially non-neutralizing. Our results suggest that the balance between neutralizing and non neutralizing responses may represent an important issue in the global response against MPER. Therefore, further redesign of immunogens able to skip non-neutralizing determinants will benefit from the knowledge derived from new anti-MPER antibodies that reflect the functional heterogeneous profile observed in our studies.

Abstract A generalized solution methodology based on piecewise linear vector fields is proposed for piecewise linear systems with singular regions or asymmetric restoring forces which vary spatially and temporally. In matrix representation for these systems, state variables in each region can be explicitly expressed as a function of the time the orbit spends between two boundaries or the time the orbit takes to pass through the boundary. The time can be determined by the Brent method, and periodic solutions can then be obtained. Analytical solutions are validated on a system with 3-regions of displacement and 2-regions of time, a circumferential vibration of gear meshing system, by using the newly developed numerical method.

Full text
Abstract:
The economics and potential offsets of imported energy are analyzed. Benefits to the carbon footprint of the region are estimated. A commercial structure for the operation of such a co-operative bio-refinery is proposed. Rural and agricultural regions typically have ample production of biomass in various forms, including wood from forestry, agricultural wastes and range grasses. Certain regions also have renewable energy resources such as wind power, solar insolation and hydraulic power. Rural regions are typically seen to have a potential for renewable energy that greatly exceeds energy consumption due to human activity in the region. However, energy consumption in such areas is highly biased toward non-renewable sources, just as in more urbanized regions. This is due to the standardization of virtually all manufactured energy conversion equipment to use available processed energy sources such as electricity and natural gas and refined fuels such as diesel and gasoline. In addition, agricultural activities are highly dependent on energy-intensive petrochemicals such as fertilizers, pesticides, and herbicides. Energy sustainability and self-sufficiency can therefore be increased by conversion of local renewable resources into appropriate form values for existing energy conversion equipment. Solar power, wind power and hydropower are fully commercial, although more economic in some regions than in others. The production of electricity from biomass fuels via conventional steam cycles is well established, if challenging from an economic standpoint. However, conversion of biomass and other renewable resources into fuels that can be used in standard equipment, and chemicals and fertilizers for local agricultural production is both technically and economically challenging. The authors evaluate the potential for a typical rural region to offset imports of conventional non-renewable energy such as electricity, engine fuels, and fertilizers via the establishment of a regional bio-refinery financed and operated as a local co-operative. The renewable resources of the typical rural region are assumed to facilitate the analysis. The appropriate technologies, scope, product slate, production rates, capital costs and operating costs for the bio-refinery are defined.

Abstract:
Abstract The instability of rotor-hydrodynamic bearing systems has been a major concern in higher-speed rotating machine design. The threshold speed seems to be a barrier that cannot be driven through. However, if some kind of external damping is introduced, the situation may be different. At first, the study is conducted on the Jeffcott rotor with external damping for both vertical and horizontal configurations. For the vertical system, it has been shown by both analytical and numerical study that there is a threshold speed at which the rotor will get into an upper stable region from the previous unstable region. As for the horizontal system, an extended Lund Stability Method is presented, which, and with numerical analysis, has proven that the system may have two threshold speeds, which evolve a stability pattern as one region of instability sandwiched between two regions of stability. Then, the study is expanded to the extended Jeffcott rotor. With the introduction of equivalent journal mass, another threshold speed appears which forms a top and final boundary to the stable operation of the rotor. The results of a numerical study show that with the external damping increased, the first several unstable regions can be reduced or eradicated. The external damping has little effect on the last top threshold which is mainly dependent on the value of journal mass. It has also been shown that a certain value of external damping and small portion of journal mass would be very beneficial to improve the stability characteristics of the system over the entire speed range.

Abstract:
Recently meshes of engineering objects are easily acquired by 3D laser or high energy X-ray CT scanning systems, and these meshes are widely used in product developments. To effectively use scanned meshes in engineering applications, such as inspection, CAD model reconstruction, and convergent-type CAE, we need to segment meshes and extract desirable regions and their approximating surfaces as preprocessing. Engineering objects are commonly represented as a set of analytic surfaces, such as planes, cylinders, spheres, cones, and tori. Therefore, the mesh surface of engineering objects needs to be approximated as a set of analytic surfaces. Moreover, a mesh surface should be approximated with a minimum number of analytic surfaces and their approximating error should be minimized as a result of segmentation. We call the segmentation that satisfies these two conditions the optimal segmentation as proposed in [1]. However, optimal segmentation algorithms need a long calculation time. Today’s high energy X-ray CT scanning systems generate large meshes with millions of triangles from objects including hundreds of regions. Thus, computationally expensive algorithms, such as [1], cannot be directly applied to these large and complex meshes from the aspect of efficiency. In this paper we propose an efficient new quasi-optimal mesh segmentation algorithm via region growing and region merging. First, our algorithm robustly and accurately estimates mesh principal curvatures using the local surface fitting by two-pass algorithm. Second, it uses the curvatures to appropriately create seed regions, and then it quickly grows each seed region and extracts grown regions and their approximating analytic surfaces from a whole mesh. Finally, our region merging algorithm efficiently merges extracted regions in order to minimize the number of regions while keeping the user specified tolerances of the surface fitting, and it results in quasi-optimal segmentation. We demonstrate the performance of our algorithm with scanned meshes acquired from real engineering objects by 3D laser and X-ray CT scanning systems.

Abstract:
This paper addresses a practical problem: “What portion of fairing or strake coverage may be lost or damaged, before the operator must take corrective measures?” This paper explores the effect of lost fairings (the exposure length) on Vortex-Induced Vibration (VIV) of flexible cylinders. The source of data is a recent model test, conducted by SHELL Exploration and Production. A 38m long pipe model with varying amounts of fairings was tested. Response as a function of percent exposure length is reported. Unexpected results are also reported: (i) the flexible ribbon fairings used in the experiment did not suppress VIV at speeds above 1 m/s; (ii) Above 1 m/s, a competition was observed between VIV excited in the faired and bare regions of the cylinder, (iii) Unusual traveling wave behavior was documented—waves generated in the bare region periodically changed direction, and exhibited variation in VIV response frequency. The results of these tests showed that (1) the excitation on the bare and faired regions could be identified by frequency, because the faired region exhibited a much lower Strouhal number; (2) as expected, the response to VIV on the bare region increased with exposure length; (3) the response to VIV on the faired region decreased with exposure length.

Abstract:
I mange sammenhenger omtales arbeidsinnvandrere som midlertidig arbeidskraft. For Vestlandet er de mye mer. De er og vil i fremtiden fortsatt kunne være en viktig ressurs for næringer og lokalsamfunn. Men dette forutsetter strategier og engasjement fra berørte lokale og regionale aktører, foruten selvsagt også vilje til deltakelse fra arbeidsinnvandrerne selv. Disse temaene har vært de sentrale i forskningsprosjektet “Arbeidsinnvandring til Vestlandet. Arbeidsinnvandring som ressurs i regional utvikling” som har vært gjennomført i de fire vestlandsfylkene Møre og Romsdal, Sogn og Fjordane, Hordaland og Rogaland i perioden 2013-2016. Prosjektet har hatt som hovedmål å utvikle kunnskap om arbeidsinnvandringens rolle og betydning i regionen. Vi har særlig lagt vekt på i hvilken grad og hvordan kommunene på Vestlandet, i eget arbeid og i samarbeid med andre aktører, har håndtert arbeidsinnvandringen slik at det ressurspotensialet som denne gruppen representerer for arbeidslivet og samfunnslivet har blitt ivaretatt på best mulig måte. Prosjektet har bestått av tre delprosjekt som hver for seg belyser ulike sider ved kommuners og fylkeskommuners måte å arbeide på i møte med arbeidsinnvandringen til landsdelen. Første delprosjekt har lagt vekt på å fremskaffe ny kunnskap om hvem arbeidsinnvandrerne til Vestlandet er, hvor de bosetter seg og hvilke næringer de arbeider innenfor samt hvilke effekter arbeidsinnvandringen kan sies å ha, særlig når det gjelder demografisk utvikling og næringsliv. Delprosjekt to har omhandlet møtet mellom arbeidsinnvandrerne og det kommunale tjenesteapparatet, kommunenes politikk og organisering av tjenestetilbudet overfor arbeidsinnvandrerne som gruppe samt hvordan tjenestetilbudet overfor denne gruppen fungerer. Delprosjekt tre har belyst kommunenes og fylkeskommunenes tilrettelegging av informasjon for arbeidsinnvandrere og hvorvidt denne målgruppen opplever denne informasjonen som relevant og tilfredsstillende. Resultatene fra de tre delprosjektene blir grundig redegjort for i hver sin del av den foreliggende rapporten, henholdsvis i kapittel 2, 3 og 4. Avslutningsvis, i kapittel 5, forsøker vi i kortform å trekke frem hovedpoenger og motivasjon for at kommuner og fylkeskommuner på Vestlandet skal jobbe videre med de utfordringer som har kommet frem i vår forskning. I dette innledende kapitlet gis en samlet oversikt over forskningsprosjektet. Bakgrunn, problemstillinger og opplegg blir gjort nærmere rede for i avsnittene 1.1 – 1.3. Hva vi har funnet gjennom våre undersøkelser fremgår så av avsnittene 1.4 – 1.9. I avsnitt 1.10 trekkes frem noen utfordringer som vil være viktig å gripe fatt i for å realisere det potensial som arbeidsinnvandrere representerer for landsdelen.

Abstract:
Disponer de información temprana sobre la evolución de la actividad económica regional se ha convertido en una prioridad, especialmente como herramienta para evaluar choques a la economía como el ocurrido con la pandemia del Covid-19. En este estudio se construyó un indicador coincidente mensual de actividad económica (IMAE) para la región Caribe, enmarcado en un modelo factorial dinámico y estimado por medio del filtro de Kalman, para el periodo comprendido entre enero de 2001 y diciembre de 2020. El indicador está compuesto por trece variables representativas de las principales actividades económicas de la región. Los resultados muestran que los movimientos experimentados por el indicador en 2020 se comportaron acorde con las medidas de aislamiento aplicadas y con las tasas de incidencia de contagios. Según cifras preliminares, en 2020 la economía del Caribe cayó en un 6,8%, equivalente al resultado nacional. En particular, el desempeño regional se vio afectado al cierre del año por la parálisis en la actividad minera y las nuevas medidas restrictivas.
