ABSTRACT Expression of the lsrA gene from Rahnella aquatilis, encoding levansucrase, is tightly regulated by the growth phase of the host cell; low-level expression was observed in the early phase of cell growth, but expression was significantly stimulated in the late phase. Northern blot analysis revealed that regulation occurred at the level of transcription. The promoter region was identified by primer extension analysis. Two opposite genetic elements that participate in the regulation of lsrA expression were identified upstream of the lsrA gene: the lsrS gene and the lsrR region. The lsrS gene encodes a protein consisting of 70 amino acid residues (M r, 8,075), which positively activated lsrA expression approximately 20-fold in a growth phase-dependent fashion. The cis-acting lsrR region, which repressed lsrA expression about 10-fold, was further narrowed to two DNA regions by deletion analysis. The concerted action of two opposite regulatory functions resulted in the growth phase-dependent activation of gene expression in Escherichia coli independent of the stationary sigma factor σS.

ABSTRACT The regulatory network for the uptake of Escherichia coli autoinducer 2 (AI-2) is comprised of a transporter complex, LsrABCD; its repressor, LsrR; and a cognate signal kinase, LsrK. This network is an integral part of the AI-2 quorum-sensing (QS) system. Because LsrR and LsrK directly regulate AI-2 uptake, we hypothesized that they might play a wider role in regulating other QS-related cellular functions. In this study, we characterized physiological changes due to the genomic deletion of lsrR and lsrK. We discovered that many genes were coregulated by lsrK and lsrR but in a distinctly different manner than that for the lsr operon (where LsrR serves as a repressor that is derepressed by the binding of phospho-AI-2 to the LsrR protein). An extended model for AI-2 signaling that is consistent with all current data on AI-2, LuxS, and the LuxS regulon is proposed. Additionally, we found that both the quantity and architecture of biofilms were regulated by this distinct mechanism, as lsrK and lsrR knockouts behaved identically. Similar biofilm architectures probably resulted from the concerted response of a set of genes including flu and wza, the expression of which is influenced by lsrRK. We also found for the first time that the generation of several small RNAs (including DsrA, which was previously linked to QS systems in Vibrio harveyi) was affected by LsrR. Our results suggest that AI-2 is indeed a QS signal in E. coli, especially when it acts through the transcriptional regulator LsrR.

Streszczenie:
LsrK is one of the key components of theluxS-regulated (lsr) operon inEscherichia coliand plays an important role during the quorum-sensing (QS) process mediated by autoinducer-2 (AI-2). The AI-2 molecule is imported into the cell by the LsrACB transporter and is subsequently phosphorylated (to AI-2-P) by LsrK. AI-2-P binds to the repressor protein of thelsroperon (LsrR) and triggers various cellular responses related to QS by dissociating LsrR from the DNA. Although a large amount of purified LsrK is required for structural studies, recombinant GST-LsrK was mostly expressed in an insoluble form. To enhance the soluble expression of LsrK, an attempt was made to increase the expression of the cellular chaperone proteins that are well known to support proper protein folding. TransformedE. coliwas cultured in high-salt LB medium and heat shock was applied prior to subsequent IPTG induction at 20°C. These procedures increased the yield of purified LsrK by about tenfold compared with standard IPTG induction at 20°C. The expressed LsrK was readily purified by GST-affinity chromatography. Crystals of LsrK were grown by the hanging-drop vapour-diffusion method. The X-ray diffraction data of the crystal were processed in a primitive hexagonal space group to 2.9 Å resolution.

Experiments have been performed on the low speed research compressor (LSRC) at General Electric Aircraft Engines to investigate the effects of flow coefficient, stagger angle, and tip clearance on tip vortex. Time resolved casing pressure distributions over the third stage rotor have been acquired with high-frequency-response pressure transducers. Also, tip vortex strength and trajectory have been estimated from the casing pressure fluctuations which have been obtained simultaneously from various axial locations. As flow coefficient decreases, tip vortex gets strengthened and migrates upstream. The stagger angle increase weakens the tip vortex and moves it downstream slightly because the blade loading is decreased. However, tip leakage vortex is influenced mainly by tip clearance, and there exists a “critical” tip clearance which determines the type of tip vortex trajectory (“straight” or “kinked”). As predicted by others, tip vortex gets strengthened with increasing tip clearance. However, unlike the predictions, the tip vortex trajectory moves upstream with increasing tip clearance. Furthermore, with tip clearance above a “critical” value, the tip vortex trajectory is no longer straight but shows a kink in the passage.

ABSTRACT The bacterial quorum-sensing autoinducer 2 (AI-2) has received intense interest because the gene for its synthase, luxS, is common among a large number of bacterial species. We have identified luxS-controlled genes in Escherichia coli under two different growth conditions using DNA microarrays. Twenty-three genes were affected by luxS deletion in the presence of glucose, and 63 genes were influenced by luxS deletion in the absence of glucose. Minimal overlap among these gene sets suggests the role of luxS is condition dependent. Under the latter condition, the metE gene, the lsrACDBFG operon, and the flanking genes of the lsr operon (lsrR, lsrK, tam, and yneE) were among the most significantly induced genes by luxS. The E. coli lsr operon includes an additional gene, tam, encoding an S-adenosyl-l-methionine-dependent methyltransferase. Also, lsrR and lsrK belong to the same operon, lsrRK, which is positively regulated by the cyclic AMP receptor protein and negatively regulated by LsrR. lsrK is additionally transcribed by a promoter between lsrR and lsrK. Deletion of luxS was also shown to affect genes involved in methionine biosynthesis, methyl transfer reactions, iron uptake, and utilization of carbon. It was surprising, however, that so few genes were affected by luxS deletion in this E. coli K-12 strain under these conditions. Most of the highly induced genes are related to AI-2 production and transport. These data are consistent with the function of LuxS as an important metabolic enzyme but appear not to support the role of AI-2 as a true signal molecule for E. coli W3110 under the investigated conditions.

This paper focuses on the effect of hub clearance in the design space of the highly loaded cantilevered stator. The embedded 1.5 stages of a low-speed research compressor (LSRC) were conducted with Unsteady Reynolds Average Navier-Stokes (URANS) numerical investigation, and the cantilevered stator adopts positive bowed and fore-sweep three-dimensional design. The research details that with the hub clearance increasing from 1.1% to 4.5% span, the loss coefficient and the total leakage momentum of the cantilevered stator correspond to the change of the blade loading near the hub. When designing the inlet metal angle of the rotor downstream the cantilevered stator, emphasis should be given to considering the inter-stage matching below 15% span. The mixing of leakage flow in 1.1% span clearance and 2.5% span clearance is basically completed in the S3 passage, but the mixing of leakage flow in 3.5% span clearance and 4.5% span clearance is still relatively strong downstream of S3. When calculating the relative entropy variation based on Denton’s mixing model, attention should be paid to the relationship between the leakage flow velocity affected by the hub gap and the mainstream velocity, as well as whether the mixing has been completed in the blade passage.

As an opportunistic pathogen, Escherichia coli (E. coli) forms biofilm that increases the virulence of bacteria and antibiotic resistance, posing a serious threat to human and animal health. Recently, ginkgetin (Gin) has been discovered to have antiinflammatory, antioxidant, and antitumor properties. In the present study, we evaluated the antibiofilm and antibacterial synergist of Gin against E. coli. Additionally, Alamar Blue assay combined with confocal laser scanning microscope (CLSM) and crystal violet (CV) staining was used to evaluate the effect of antibiofilm and antibacterial synergist against E. coli. Results showed that Gin reduces biofilm formation, exopolysaccharide (EPS) production, and motility against E. coli without limiting its growth and metabolic activity. Furthermore, we identified the inhibitory effect of Gin on AI-2 signaling molecule production, which showed apparent anti-quorum sensing (QS) properties. The qRT-PCR also indicated that Gin reduced the transcription of curli-related genes (csgA, csgD), flagella-formation genes (flhC, flhD, fliC, fliM), and QS-related genes (luxS, lsrB, lsrK, lsrR). Moreover, Gin showed obvious antibacterial synergism to overcome antibiotic resistance in E. coli with marketed antibiotics, including gentamicin, colistin B, and colistin E. These results suggested the potent antibiofilm and novel antibacterial synergist effect of Gin for treating E. coli infections.

Rotating instabilities (RIs) have been observed in axial flow fans and centrifugal compressors as well as in low-speed and high-speed axial compressors. They are responsible for the excitation of high amplitude rotor blade vibrations and noise generation. This flow phenomenon moves relative to the rotor blades and causes periodic vortex separations at the blade tips and an axial reversed flow through the tip clearance of the rotor blades. The paper describes experimental investigations of RIs in the Dresden Low-Speed Research Compressor (LSRC). The objective is to show that the fluctuation of the blade tip vortex is responsible for the origination of this flow phenomenon. RIs have been found at operating points near the stability limit of the compressor with relatively large tip clearance of the rotor blades. The application of time-resolving sensors in both fixed and rotating frame of reference enables a detailed description of the circumferential structure and the spatial development of this unsteady flow phenomenon, which is limited to the blade tip region. Laser-Doppler-anemometry (LDA) within the rotor blade passages and within the tip clearance as well as unsteady pressure measurements on the rotor blades show the structure of the blade tip vortex. It will be shown that the periodical interaction of the blade tip vortex of one blade with the flow at the adjacent blade is responsible for the generation of a rotating structure with high mode orders, termed a rotating instability.

A Large Scale Robot Colony (LSRC) is a complex artifact comprising of a significant population of both mobile and static robots. LSRC research is in its literary infancy and it is therefore necessary to rely upon external fields for the appropriate framework, Multi Agent Systems (MAS) and Large Scale Systems (LSS). At the intersection of MAS, LSS and LSRC exist near identical issues, problems and solutions. If attention is paid to coherence then solution portability is possible. The issue of Self-Reliability is poorly addressed by the MAS research field. Disparity between the real world and simulation is another area of concern. Despite these deficiencies, MAS and LSS are perceived as the most appropriate frameworks. MAS research focuses on three prime areas, cognitive science, management and interaction. LSRC is focused on Self-Sustainability, Self-Management and Self-Organization. While LSS research was not primarily intended for populations of mobile robots, it does address key issues of LSRC, such as effective sustainability and management. Implementation of LSRC that is based upon the optimal solution for any one or two of the three aspects will be inferior to a coherent solution based upon all three. LSRC’s are complex organizations with significant populations of both static and mobile robots. The increase in population size and the requirement to address the issue of Self-Reliance give rise to new issues. It is no longer sufficient to speak only in terms of robot intelligence, architecture, interaction or team behaviour, even though these are still valid topics. Issues such as population sustainability and management have greater significance within LSRC. As the size of a robot populations increases, minor uneconomical decisions and actions inhibit the performance of the population. Interaction must be made economical within the context of the LSRC. Sustainability of the population becomes significant as it enables stable performance and extended operational lifespan. Management becomes significant as a mechanism to direct the population so as to achieve near optimal performance. The Self-Sustainability, Self-Management and Self-Organization of LSRC are vastly more complex than in team robotics. Performance of the overall population becomes more significant than individual or team achievement. This thesis is a presentation of the Cooperative Autonomous Robot Colony (CARC) architecture. The CARC architecture is novel in that it offers a coherent baseline solution to the issue of mobile robot Self-Reliance. This research uses decomposition as a mechanism to reduce problem complexity. Self-Reliance is decomposed into Self-Sustainability, Self-Management, and Self-Organization. A solution to the issue of Self-Reliance will comprise of conflicting sub-solutions. A product of this research is a set of guidelines that manages the conflict of sub-solutions and maintains a coherent solution. In addressing the issue of Self-Reliance, it became apparent that Economies of Scale, played an important role. The effects of Economies of Scale directed the research towards LSRC’s. LSRC’s demonstrated improved efficiency and greater capability to achieve the requirements of Self-Reliance. LSRC’s implemented with the CARC architecture would extend human capability, enabling large scale operations to be performed in an economical manner, within real world and real time environments, including those of a remote and hostile nature. The theory and architecture are supported using published literature, experiments, observations and mathematical projections. Contributions of this work are focused upon the three pillars of Self-Reliance addressed by CARC: Self-Sustainability, Self-Management and Self-Organization. The chapter on Self-Sustainability explains and justifies the relevance of this issue, what it is, why it is important and how it can be achieved. Self-Sustainability enables robots to continue to operate beyond disabling events by addressing failure and routine maintenance. Mathematical projections are used to compare populations of non-sustained and sustained robots. Computer modeling experiments are used to demonstrate the feasibility of Self-Sustainability, including extended operational life, the maintenance of optimal work flow and graceful physical degradation (GPD). A detailed explanation is presented of Sustainability Functions, Colony Sites, Static Robot Roles, Static Robot Failure Options, and Polymorphism. The chapter on Self-Management explores LSS research as a mechanism to exert influence over a LSRC. An experimental reactive management strategy is demonstrated. This strategy while limited does indicate promising potential directions for future research including the Man in the Loop (MITL) strategy highly desired by NASA JPL for off world command and control of a significant robot colony (Huntsberger, et. al., 2000). Experiments on Communication evaluate both Broadcast Conveyance (BC) and Message Passing Conveyance (MPC). These experiments demonstrate the potential of Message Passing as a low cost system for LSRC communication. Analysis of Metrics indicates that a Performance Based Feedback Method (PBFM) and a Task Achievement Method (TAM) are both necessary and sufficient to monitor a LSRC. The chapter on Self-Organization describes a number of experiments, algorithms and protocols on Reasoning Robotics, a minor variant of Reactive Robotics. Reasoning Robotics utilizes an Event Driven Architecture (EDA) rather than a Stimulus Driven Architecture (SDA) common to Reactive Robotics. Enhanced robot performance is demonstrated by a combination of EDA and environmental modification enabling stigmergy. These experiments cover Intersection Navigation with contingency for Multilane Intersections, a Radio Packet Controller (RPC) algorithm, Active and Passive Beacons including a communication protocol, mobile robot navigation using Migration Decision Functions (MDF’s), including MDF positional errors. The central issue addressed by this thesis is the production of Self-Reliance guidelines for LSRC’s. Self-Reliance is perceived as a critical issue in advancing the useful and productive applications for LSRC’s. LSRC’s are complex with many issues in related fields of MAS and LSS. Decomposition of Self-Reliance into Self-Sustainability, Self-Management and Self-Organization were used to aid in problem understanding. It was found that Self-Sustainability extends the operational life of individual robots and the LSRC. Self-Management enables the exertion of human influence over the LSRC, such that the ratio of humans to robots is reduced but not eliminated. Self-Organization achieves and enhances performance through a routine and reliable LSRC environment. The product of this research was the novel CARC architecture, which consists of a set of Self-Reliance guidelines and algorithms. The Self-Reliance guidelines manage conflict between optimal solutions and provide a framework for LSRC design. This research was supported by literature, experiments, observations and mathematical projections.

Between April 27th 1995 and April 26th 2005, patients with external cause lesions seen at the pediatric orthopedic outpatient clinic of the Maria Amelia Lins Hospital were studied. The objective was to identify the characteristics, patients profile through the variables: age, gender, trauma mechanism, side, topographic localization, associated injuries and compare the epidemiological results with the literature findings. The inclusion criterias were: have a external cause lesion, find the medical records with the appropriate research informations and have open physes. In the above mentioned period 2472 patients were identified, of which 1199 fitted the inclusion criterias. Patients identification and lesion characteristics were taken from the medical records. Age was count in absolute years. Mechanism of trauma were grouped in falls, traffic accidents, direct trauma, others and without information. Thetypes of lesions were divided in amputation, fractures, epiphysiolises, luxations, head trauma, contusions, internal organs injuries, face injuries, and others. Fractures, fracture-luxation, epiphysiolises and luxations were, also, classified as open or closed. Topographic localizationswere classified in relation to bony segments. Patients were grouped in general population, isolated injuries, multiple lesions that had more then one segment and/or of other organs involved. The orthopedic injuries that required more secondary attention were described asprincipal. From the general sample, 838 (68.9%) patients had isolated injuries, 361 (30.1%) patients had 884 multiple lesions. Mean age was 7.6±3.4 years. Masculine gender and the left side predominated. In the isolated injuries the upper limbs were more affected while lowerlimbs were more affected in multiple lesions. The most common trauma mechanisms in general and isolated groups, were falls (39.0% e 44,3%) and traffic accidents in multiple injuries (42,7%). Fracture was the most frequent type of lesion was (73,0% - general sample, 85,3% - isolated injuries and 61,1% - in multiple injuries). Elbow fractures (24%) were the most common topographic localization among the isolated injuries, while leg fractures (12,9%) were the most common among the multiple injuries. One associated injury was seen in 67.% of the multiple lesions 24.3% had two, 5.3% had three and 3.3% had four. Mainly the associationamong elbow fractures and forearm fractures with 25 cases. In conclusion, the descriptive characteristics were the same as the literature. The isolated injury patients´ profile is: boys, inschool age, victims of fall, with upper limb long bone closed fractures. The multiple injury patients´ profile is: boys, at school age, victims of traffic accidents, with lower limb long bone fractures associated with other injuries. Protocols development and introduction are of essential for bias exclusion and comparison in this type of study.

Os tipos de lesões foram subdivididos em amputações; fraturas; epifisiólise; luxações; traumatismo cranioencefálico; contusões; lesões de órgãos internos; lesões de face; e outras lesões. As fraturas, fraturas-luxações, as epifisiólises e luxações foram classificadas, quanto à exposição, em expostas e fechadas. A localização topográfica das lesões foi classificada em relação aos segmentos ósseos nos quais ocorreram. Os pacientes foram agrupados em amostra geral, portadores de lesões isoladas e portadores de lesões múltiplas, considerando-se essas últimas as que acometeram mais de um segmento do esqueleto e/ou lesões de outros órgãos ou sistemas. A lesão musculoesquelética que necessitou mais atenção secundária foi descrita como lesão principal. Da amostra geral, 838 (68,9%) pacientes tiveram lesões isoladas e 361 (30,1%) presentaram 884 lesões. A média de idade foi 7,6±3,4 anos. Houve predomínio do gênero masculino e do lado esquerdo. Os membros superiores preponderaram nas lesões isoladas e os membros inferiores nas lesões múltiplas. O mecanismo de trauma mais comum na amostra geral e no grupo lesões isoladas foi a queda(39,0% e 44,3% respectivamente) e, nas lesões múltiplas, foi o acidente de trânsito (42,7%). O tipo de lesão mais frequente foi a fratura (73,0% - amostra geral, 85,3% - lesões isoladas e 61,1% - nas múltiplas). Quanto à localização topográfica, nas lesões isoladas predominaram asfraturas de cotovelo (24%) e, nas lesões múltiplas, as fraturas dos ossos da perna (12,9%). Nos portadores de lesões múltiplas, 67,1% tinham uma lesão associada, 24,3% duas, 5,3% três, e 3,3% quatro, com destaque para as fraturas de cotovelo com as fraturas de antebraço (25 casos). Concluiu-se que as características descritivas se encontram em conformidade com aliteratura. Os portadores de lesões isoladas podem ser definidos como meninos em idade escolar, vítimas de queda, apresentando fratura fechada de osso longo do membro superior. Os portadores de lesões múltiplas caracterizaram-se por ser meninos, em idade escolar, vítimas de acidente de trânsito apresentando fratura de ossos do membro inferior acompanhada de outra lesão. O desenvolvimento e a implantação de protocolos deatendimento são de fundamental importância para a eliminação de vieses na coleta de dados nesse tipo de estudo.

This thesis gives a description and a syntactic analysis for coordination and gapping in conjunction in Catalan Sign Language (LSC) within the framework of Generative Grammar and Minimalism. Regarding coordination, Coordination Phrase (CoP) is proposed as the category for conjunctive, disjunctive and adversative coordination, assuming that the conjuncts are specifiers and complements of CoP in a right-branching coordination structure. The specific derivation for each types of coordination is then applied. As for gapping in conjunction, in LSC it shows similarities with VP-ellipsis, especially because it can appear also in subordination. Moreover, the availability of only distributed scope negation (¬A&¬B) and the presence of contrastive topic and contrastive focus require a large coordination structure, that is, CP coordination. In order to derive gapping, I propose movement of the arguments to TopP and FocP followed by the deletion of TP at PF, with [E] feature in the head of FocP.
Aquesta tesi ofereix una descripció i una anàlisi sintàctica per a la coordinació i el “gapping” en coordinació conjuntiva en llengua de signes catalana (LSC), dins el marc generativista i minimista. Pel que fa a la coordinació, la categoria sintàctica que es proposa és “Coordination Phrase” (CoP) per a la coordinació conjuntiva, disjuntiva i adversativa. A l’estructura, ramificada a la dreta, els constituents de la conjunció són especificadors i complements de CoP. La derivació per a cada tipus de coordinació s’aplica a partir d’aquest model. Pel que fa al “gapping”, mostra proprietats similars a l’el·lipsi de SV (VP-ellipsis), sobretot perquè pot aparèixer en subordinació. A més, la l’existència només d’un abast distribuït de la negació (¬A&¬B) i la presència de tòpic i focus contrastius mostra la necessitat de tenir una coordinació “àmplia” on els dos conjunts siguin CPs. En la derivació de “gapping”, els arguments es mouen a TopP i FocP, seguits de l’eliminació del TP a PF, ambel tret [E] posicionat al nucli de FocP.

This thesis provides a morphosyntactic description of polar questions and a pragmatic analysis of biased questions in Catalan Sign Language (LSC). Polar questions in LSC are obligatorily marked with a specific combination of non-manual marking features and optionally marked with a question particle. Given that, at least, the most prominent feature, eyebrow position, does not remain constant, LSC displays different combinations of non-manuals to mark this structure. Empirical evidence supports an analysis in which each combination of non-manuals conveys a different bias and a novel feature-based description system explains and predicts those. Therefore, each combination of non-manuals, as well as the appearance of the question particle, is shown to not only mark sentence type but also to encode specific pragmatic meanings.

Ates que, si més no, el tret més destacat, la posició de les celles, no roman constant, l’LSC mostra diferents combinacions de no manuals per marcar aquesta estructura. L’evidencia científica dona suport a una anàlisi en què cadascuna de les combinacions de no manuals codifica un biaix diferent; un nou sistema de descripció basat en trets explica i prediu aquest comportament. Per tant, cada combinació de no manuals, així com l’aparició de la partícula interrogativa, es realitza no nomes per marcar el tipus d’oració, sinó també per codificar significats pragmàtics.

This thesis provides a description and a pragmatic analysis of the expression and interpretation of focus and contrast in Catalan Sign Language (LSC). I argue that LSC data provides empirical evidence that contrast is an independent notion in Information Structure that can overlap with topics and foci, and that involves different types, which are built compositionally. All types of contrast share a basic meaning (semantic parallelism), which is essential for an element to be contrastive, and which is expressed through a specific combination of non-manual markers (NMMs). Additional prosodic NMMs are used to trigger more complex meanings, like exhaustivity or counterexpectation. Moreover, a first description of focus particles and clefts in LSC is provided, together with a pragmatic analysis of exhaustivity and non-truth conditional meaning (presuppositions and implicatures) in these constructions.
Aquesta tesi proporciona una descripció i una anàlisi pragmàtica de l’expressió i la interpretació del focus i el contrast en llengua de signes catalana (LSC). Defenso que l’LSC aporta proves empíriques que el contrast és una noció independent en el camp de l’estructura informativa que se solapa amb el tòpic i els focus de l’oració i que es pot dividir en subtipus que es conformen de manera composicional. Tots els tipus de contrast comparteixen un significat bàsic (paral·lelisme semàntic), que és imprescindible perquè un element sigui contrastiu i que s’expressa a través d’una combinació específica de marcadors no manuals (MNM). MNM addicionals són emprats per expressar significats més complexos, com ara l’exhaustivitat i la contraexpectació. A més, s’ofereix una primera descripció de les partícules focals i les oracions clivellades en LSC, i una anàlisi pragmàtica de l’exhaustivitat i el significat no veritatiu-condicional (implicatures i pressuposicions) que es deriva d’aquestes construccions.

Languages use different resources to specify the numerosity of the referents and to denote the speech act participants. This thesis describes the morphophonological strategies used in Catalan Sign Language (LSC) personal pronouns to encode these distinctions. In a nutshell, I argue that the expression of person and number is achieved by using two interrelated strategies: person is expressed through spatial features (locations in the signing space which are defined in relation to the signer’s body), number is grammatically marked by the path specifications of the sign (movements connecting spatial locations). Combining these two operations results in the formal marking of three person distinctions (with a further contrast between exclusive, minimal inclusive and augmented inclusive in the first person) and four number values (singular, dual, paucal and plural).
Les llengües utilitzen diferents recursos per a expressar el nombre dels referents i designar als participants en els actes de parla. Aquesta tesi descriu les estratègies morfofonològiques utilitzades als pronoms personals de la llengua de signes catalana (LSC) per a codificar aquestes distincions. En resum, es proposa que les categories de persona i nombre s’expressen utilitzant dues estratègies interrelacionades: la persona s’expressa a través de trets espacials (localitzacions a l’espai sígnic definides en relació amb el cos del parlant), el nombre es marca gramaticalment a través d’especificacions en la trajectòria del signe (moviments que connecten localitzacions espacials). La combinació d’aquestes dues operacions es tradueix en la codificació formal de tres distincions de persona (amb una oposició addicional entre exclusivitat, inclusivitat mínima i inclusivitat augmentada en la primera persona) i quatre valors de nombre (singular, dual, paucal i plural).

Streszczenie:
Le Lipolysis Stimulated Receptor (LSR) fixe les lipoprotéines contenant l'apolipoprotéine (apo) B et l'apoE en présence des acides gras, et son affinité est optimale pour les fractions lipoprotéiniques les plus riches en triglycérides. Dans notre étude, nous avons utilisé les techniques du Northern blot, de la PCR quantitative en temps réel et de l'immunofluorescence pour examiner l'expression du LSR chez la souris adulte et au cours du développement embryonnaire. Chez l'adulte l'ARNm LSR est retrouvé dans tous les tissus étudiés sauf dans le muscle et le coeur. Les ARNm sont abondants dans le foie, le poumon, l'intestin, le rein et dans certains tissus stéroidogéniques (ovaires et testicules). Ils sont également présents à tous les stades embryonnaires étudiés. Les résultats de l'expression protéique sont corrélés à ceux de l'expression transcriptionnelle. Ainsi, le "patron" d'expression du LSR chez la souris adulte apporte des arguments supplémentaires sur son rôle possible de ce récepteur dans le transport lipidique au niveau de ces organes. Afin d'étudier le rôle physiologique du LSR in vivo, nous avons tenté d'obtenir des souris LSR-/- par recombinaison homologue. Sur un total de 379 souris génotypées, trois homozygotes seulement ont été identifiées. Cette répartition montre une grande létalité des homozygotes. Celle-ci se produit entre 12,5 et 15,5 jours de gestation. Les embryons LSR-/- se distinguent par un foie de taille réduite. Ces résultats indiquent que le LSR est indispensable pour le développement embryonnaire. Par ailleurs, étant donné que les souris hétérozygotes ne présentent aucun phénotype particulier, nous avons voulu analyser l'impact de l'invalidation de l'un des deux allèles du LSR chez des souris totalement déficientes en un autre récepteur de lipoprotéines à apoB/E, le LDLR. Comparés aux souris LDL-/-, les doubles mutants [LSR+/- ; LDR-/-] appelés LDLSR ont des taux plasmatiques de cholestérol total significativement plus faibles par diminution du cholestérol contenu dans les lipoprotéines non LDL et HDL. Ce résultat pourrait être expliqué par l'intervention de mécanismes compensateurs comme l'augmentation de l'activité d'autres récepteurs de lipoprotéines. Grâce au modèle LDLSR, nous avons pu mettre en évidence pour la première fois un rôle in vivo du LSR dans la régulation du métabolisme du cholestérol et des lipoprotéines
The lipolysis stimulated receptor (LSR) recognizes apolipoprotein B/E-containing lipoproteins in the presence of free fatty acids, and is thought to be involved in the clearance of triglyceride-rich lipoproteins (TRL). The distribution of LSR in mice was studied by Northern blots, quantitative PCR and immunofluorescence. In the adult, LSR mRNA was detectable in all tissues except muscle and heart, and was abundant in liver, lung, intestine, kidney, ovaries and testes. During embryogenesis, LSR mRNA was detectable at 7. 5 days post-coitum (E7) and increased up to E17 in parallel to prothrombin, a liver marker. In adult liver, immunofluorescence experiments showed a staining at the periphery of hepatocytes as well as in fetal liver at E12 and E15. These results are in agreement with the assumption that LSR is a plasma membrane receptor involved in the clearance of lipoproteins by liver, and suggest a possible role in steroidogenic organs, lung, intestine and kidney. To explore the role of LSR in vivo, the LSR gene was inactivated in 129/Ola ES cells by removing a gene segment containing exons 2-5, and 129/Ola-C57BL/6 mice bearing the deletion were produced. Although heterozygotes appeared normal, LSR homozygotes were not viable, with the exception of three males, while the total progeny of genotyped wild-type and heterozygote pups was 376. Mortzality of the homozygote embryos was observed between days 12. 5 and 15. 5 of gestation, a time at which their liver was much smaller than that of their littermates, indicating that the expression of LSR is critical for liver and embryonic devellopment. To evaluate the effect of inactivation of one allele LSR in LDL receptor-deficient mice, we produce double knockout animals [LSR+/-] called LDLSR Total plasma cholesterol concentration were approximately 40 % less as compared with LDLR-/- mice These finding supported the hypothesis of upregulation of other receptors in LDLSR mice

Aquesta tesi presenta la primera descripció de les construccions relatives (CR) restrictives en llengua de signes catalana (LSC). A més, inclou una proposta d’anàlisi en el marc de la gramàtica generativa transformacional informada tipològicament. Respecte a la tipologia sintàctica de les CR, aportem proves que mostren que aquestes construccions, en LSC, són estructures circumnominals, és a dir, amb el pivot (o antecedent) dins de l’oració relativa (OR). Això contrasta amb les CR més comunes a les llengües indoeuropees, les adnominals, en què el pivot apareix fora de l’OR. Les CR circumnominals de la LSC, d’acord amb el que diu la tipologia, presenten un determinant que nominalitza l’estructura. Les CR circumnominals de la LSC no apareixen mai a la seva posició bàsica dins de l’oració matriu sinó que han d’aparèixer o bé avantposades o bé posposades. Aquesta mateixa distribució s’observa a les CR circumnominals d’altres llengües de signes, com ara la llengua de signes italiana (LIS). L’anàlisi que presentem és essencialment la d’elevació, en la línia de Kayne (1994), encara que hi introduïm algunes modificacions per tal de donar compte de les dades de la LSC. Aquesta anàlisi, en principi, seria d’aplicació a les CR circumnominals en general, es tracti de llengües orals o signades. Aquest treball representa, doncs, una contribució tant a la tipologia com a la lingüística teòrica.
This work contains the first description of Catalan Sign Language (LSC) Relative Clauses (RCs). Also, it proposes an analysis within the Generative framework that takes a typological approach. Regarding the syntactic typology of LSC RCs, they are circumnominal. In other words, they show the pivot (or antecedent) inside the RC. This contrasts with the most common RCs in Indo-European languages, the adnominal ones, in which the pivot appears outside the RC, that is, in the matrix clause. Other evidence that supports the idea that RCs in LSC are circumnominal is put forward. For instance, this structure shows a determiner that nominalizes the whole construction, as usually found in circumnominal RCs across languages. Circumnominal RCs in LSC never appear in its basic position inside the matrix clause. They have to appear or fronted or postposed to the matrix one. This same distribution is also found in other sign language RCs, for instance, in Italian Sign Language (LIS). The analysis presented here essentially follows the raising one (Kayne 1994). However, I have added some modifications in order to take into account crucial LSC data. The resulting analysis can be applied to the circumnominal construction as a whole, that is, in both oral and signed languages. To sum up, this work is a contribution to both typology and theoretical linguistics.

Streszczenie:
Aquesta tesi se centra en la identificació i descripció de la categoria verb (V) en la llengua de signes catalana (LSC). Hem emmarcat la nostra recerca en el marc teòric de Borer (bàsicament 2005a i 2005b), el qual ens ha permès analitzar la LSC des d’una perspectiva diferent a d’altres treballs descriptius. Al llarg d’aquest treball descrivim els functors lèxics (FL) i els functors funcionals (FF) que hem pogut identificar per a la categoria V en el corpus objecte del nostre estudi en LSC. Seguint diverses investigacions referides a altres llengües de signes, iniciem el nostre treball amb un estudi d’un conjunt de parells nom-verb de la LSC i n’identifiquem les diferències morfofonològiques. En aquest nivell de descripció morfofonològica distingim dos FL que fan que l’arrel lèxica inserida en el nucli del SV esdevingui i s’identifiqui com a equivalent a V, cosa que permet que se li assigni una estructura eventiva. Posteriorment, analitzem els FF ( i f-morfs independents) que provoquen una alteració morfofonològica de l’arrel verbalitzada i que també permeten identificar la categoria verb. En aquest sentit, centrem el nostre estudi en les projeccions funcionals Concordança, Aspecte, Manera i Quantitat. Pel que fa a la Concordança, hem analitzat la Concordança de Persona, d’Espai i de Nombre en LSC des d’una perspectiva sintàctica. En contra de gran part dels estudis sobre la concordança en les llengües de signes, destaquem el paper de la localització com a part del de la projecció funcional Concordança de persona, fins i tot en les arrels considerades ‘invariables’. Defensem que la concordança amb els arguments segueix un ordre jeràrquic i que depèn del tipus d’estructura sintàctica. Pel que fa a l’Aspecte, postulem que la ‘telicitat’ i la ‘atelicitat’ es defineixen en els termes de quantitat d’acord amb Borer (2005a,b), i que l’aspectualitat es construeix a la sintaxi. Dels dos FL identificats al capítol 4, demostrem que un (FL1) assigna a l’arrel verbalitzada un valor semàntic no quantitatiu, mentre que l’altre (FL2#) li assigna un valor semàntic quantitatiu. Argumentem que aquesta estructura quantitativa o no quantitativa no és determinant per a la sintaxi, atès que, en primer lloc, és modificable i, en segon lloc, les arrels verbalitzades poden aparèixer en diferents contextos sintàctics independentment que la seva forma morfofonològica reflecteixi una estructura o l’altra. Així mateix, en aquest estudi demostrem l’existència d’una projecció funcional Manera i d’una projecció funcional Quantitat (diferent del FL esmentat) responsables de nombroses variacions en la morfofonologia verbal, entre les quals hi ha les interpretacions d’intensitat i pluriaccionalitat. De cada una d’aquestes projeccions funcionals en descrivim els que hem identificat en el corpus disponible, n’analitzem els diferents tipus de realitzacions morfofonològiques i les possibles restriccions que els afecten.
This thesis focuses on the identification and description of the category verb (V) in Catalan Sign Language (LSC). The research has been developed within the Borer’s theoretical framework (basically 2005a and 2005b), which has provided an approach to LSC different from the one typically found in previous descriptive studies. We describe the Lexical Functors (FL) and Functional Functors (FF) that we have identified for the category V in LSC in the corpus of our study. Following other investigations in sign languages, the present study starts with an analysis of a set of name-verb pairs in LSC, and we identify their morphophonological differences. At this level of morphophonological differences we distinguish two FL that assign an eventive structure to the root and identify it as V-equivalent. We also analyse the set of FF ( and independent f-morph) that may cause morphophonological changes in the verbalized root and contribute to identifying the category V. In this sense, the Functional Projections that are described in this thesis on the category V in LSC are: Agreement, Aspect, Manner and Quantity. Concerning Agreement, we analyse Person Agreement, Spatial Agreement and Number Agreement in LSC from a syntactic perspective. In contrast to most studies on Agreement in signed languages, we highlight the role of location as a part of the of the Person Agreement Functional Projection, even in roots classified as ‘plain roots’. We show that there is a hierarchical order that reflects Agreement with arguments and that depends on different syntactic structures. With respect to Aspect, we argue that ‘telicity’ and ‘atelicity’ are defined as Quantity, according to Borer (2005a,b), and that Aspect is built in syntax. Concerning the two FL identified for verbal roots, we show that one of them (FL1) assigns non-quantity eventive information to the verbalized root and the other (FL2#) a quantity one. We argue that this lexical eventive information is not crucial in syntax, first, because it can be modified, and, second, because verbalized roots can appear in different syntactic contexts, no matter which is its initial morphophonologycal information. Finally, in this study we show the need of a Manner Functional Projection and a Quantity Functional Projection (different from FL) to identify the category V in LSC. They both force a number of morphophonological changes in the V-equivalent roots and, consequently, they help to identify the category V. For each of them, we describe the relevant found in the corpus we have analysed, their different morphophonological realizations and the restrictions they may have.

Streszczenie:
Abstract Livestock systems research (LSR) at the International Livestock Research Institute (ILRI) sought to answer two questions: (1) What are the major livestock systems in the sub-Saharan Africa tropics and subtropics? (2) What technical and organizational changes can be introduced into these systems to make them productive? This chapter reports the answers of decades of research at ILRI, its predecessors and its principal partners to these questions. The chapter also examines the scientific and development impacts of LSR since the 1970s, and whether the development impacts of LSR be distinguished from long-term trends in African livestock systems.

Abstract The flow fields in rear stages of multi-stage axial compressor is difficult to measure in detail owing to the limited height and space. Thus, low speed research compressor (LSRC) facilities which are modelled from rear stages have been widely used to explore the internal flow fields and improve compressor design. A newly-designed vertical LSRC facility is established and put into used in Shanghai Jiao Tong University. The construction and design features of this LSRC facility are introduced in this paper. A cantilevered stage has been tested in this test rig. Compressor performance, inter-stage parameters distributions and contours are measured at design point and near stall point. Steady single passage simulations for four-stage compressor are carried out to validate numerical methods and further interpret the internal flow fields in test stages. This vertical LSRC facility consists of inlet guide vane (IGV) and four repeated stages with an external diameter of 1.5 meter and a rotating speed of 900 RPM. The third stage is the mainly tested one, while the first and second stages provide the inlet conditions and the fourth stage provides the outlet conditions. Complete measuring methods and systems are established for this newly-built LRSC facility. The measurements of overall performance and inter-stage flow fields are carried out for test stage with cantilevered stator rows. The simulation for four-stage compressor are also performed for cantilevered configuration. The results of steady single-passage simulation have a similar trend with experimental ones, in terms of overall performance and parameters distributions.

Fundamental flameholding and combustion tests using simple V-gutters for the flame holders were investigated in order to obtain basic design data of a natural gas fueled ram combustor. Then Laboratory Scaled Ram Combustor (LSRC) was designed and fabricated in the first phase of the HYPR project using the fundamental flameholding and combustion tests results. Various tests were conducted to study combustion performance, such as flame stabilization, combustion efficiency, pressure loss and so on, of the LSRC at the simulated conditions of flight Mach number 3. The results indicate that high combustion efficiency is attainable with controlling the concentration of methane air mixture flowed into a flame holder even at a low equivalence ratio.

Low-speed model testing has advantages such as great accuracy, low cost and risk, so it’s widely used in the design procedure of HPC exit stage. The low-speed model testing project is conducted in Nanjing University of Aeronautics and Astronautics, to represent aerodynamic load and flow field structure of the seventh stage of a high-performance 10-stage high-pressure compressor. This paper outlines the design work of the low speed four-repeating-stage axial compressor, the third stage of which is the testing stage. The first two stages and the last stage provide the compressor with entrance and exit conditions respectively. The high-to-low speed transformation process involves both geometric and aerodynamic considerations. Accurate similarities demand the same Mach number and Reynolds number, which will not be maintained due to motor power/size and its low-speed feature. Compromises of constraints are obvious. Modeling principles are presented in high-to-low speed transformation. Design work is carried out based on these principles. Four main procedures are proceeded subsequently in the general design, including establishment of low-speed modeling target, global parameter design of modeling stage, throughflow aerodynamic design and blading design. In global parameter design procedure, rotational speed, shroud diameter, hub-tip ratio, mid-span chord and axial spacing between stages are determined by geometrical modeling principles. During throughflow design process, radial distributions of aerodynamic parameters such as D-Factor, pressure-rise coefficient, loss coefficients, stage reaction and other parameters are obtained by determined aerodynamic modeling principles. Finally, rotor and stator blade profiles of LSRC at seven span locations are adjusted, to make sure that blade surface pressure coefficients agree well with that of the HPC. 3D flow calculations are performed on low-speed four-stage axial compressor, and the resultant flow field structures agree well with that of the HPC. It’s worth noting that a large separation zone appears in both suction surfaces of LSRC and HPC. How to diminish it through 3D blading design in LSRC test rig is our further work.

Numerical simulations with the steady 3D RANS were performed on a 4-stage low speed research compressor (LSRC) with two typical configurations (a shrouded and a redesigned cantilevered stator of the third stator). The shrouded stator (SS) with 0.67% labyrinth seal clearance of the blade height is the prototype, and the cantilevered stator (CS) with 1.2% hub clearance of the blade height is the redesigned cantilevered stator. The fourth rotor that follows after the cantilevered stator was redesigned (RE) according to blade load and inlet flow angle changed based on the redesigned cantilevered stator. The overall performance of the 4-stage LSRC and the distribution of aerodynamic parameters along the blade height were compared between the prototype and the redesigned third stator. Flow characteristics of the third stator and fourth rotor were analyzed in detail. The results indicate that the flow characteristics below the 35% blade height are very different between the prototype and the redesigned due to the effect of leakage flow from seal cavity and hub gap, respectively. The stall margin of CS is 57% higher than SS. The efficiency of CS at the design point is 0.82% higher than SS. Through the redesigned process of R4, the stall margin of RE is 45% higher than CS and the efficiency of R4 is 0.6% higher on average over the entire operating range.

This paper presents the effect of clocking on the unsteady loading of the rotor blades in the first stage with an inlet guide vane row (IGV) of the Dresden Low-Speed Research Compressor (LSRC). The unsteady flow field of the Dresden LSRC at 10 IGV clocking positions for the design point was investigated using a 3D time-accurate viscous solver. The time-averaged pressure distributions on the pressure side (PS) and the suction side (SS) of the rotor blades at midspan (MS) are presented for different clocking positions. The effect of the clocking on the time-averaged Root Mean Square-value (RMS) of the unsteady pressure fluctuations of the rotor blades at MS is investigated. The unsteady pressure fluctuations on the PS and the SS of the rotor blades at MS for different clocking positions are presented and discussed. The unsteady blade pressure forces on the rotor blades, which are calculated from the profile pressure distributions, are presented and analysed for different clocking positions. The maximal fluctuation amplitude of the unsteady pressure forces on the rotor blades, which fluctuate around the nearly identical mean values for different clocking positions, can be reduced about 60 percent with the IGV clocking for the design point in the investigated configuration. The effect of the clocking on the time-resolved inlet- and outlet flow fields of the rotor blades is investigated and discussed.

Abstract In axial compressor, the leakage flow from labyrinth cavity has a non-negligible influence on the aerodynamic performance and flow fields of shrouded stators due to its interaction with the main stream. A number of numerical researches have been carried out to predict and understand the cavity flow. However, details about the boundary conditions between cavity and mainstream are scarce in opening literature. Comparisons between numerical and experimental results are seldom reported to verify the rationality of the connecting method. Therefore, a four-stage low-speed research compressor (LSRC) with shrouded stators in Shanghai Jiao Tong University was investigated numerically in this paper, aiming at studying the influence of different cavity boundary conditions. A steady numerical research on the front 1.5-stage (IGV-rotor-stator) of LSRC was performed using NUMECA with four connecting methods for the interface between the cavity and mainstream. The investigation reveals that different boundary conditions make great impact on the aerodynamic performance and flow fields of the compressor. Validated by the experimental data, when using the full non-matching connections between cavity and mainstream while cavity domain rotating at the nominal speed, the steady three-dimensional RANS simulation of the 1.5-stage compressor can well predict the distributions of total pressure loss and flow angle near the hub at the stator outlet. The flow mechanisms of different connecting methods are elucidated by investigating the detailed flow fields inside the cavity and near the stator hub. The full-non matching cases with different rotational speeds of cavity domain from 0 to 900 RPM are also compared to demonstrate the influence of rotational speeds on performance and flow fields.

One of the main characteristics of logical-semantic relations (LSRs) between two fragments of a text is that these relations can be either explicit (expressed by some marker, e.g. a connective) or implicit (derived from the interrelation of these fragments’ semantics). Since implicit LSRs do not have any marker, it is difficult to find them in a text (whether automatically or not). In this paper, approaches to analysing implicit LSRs are compared, an original definition for them is offered and differences between implicit LSRs and LSRs expressed by non-prototypical means are described. A method is proposed to identify implicit LSRs using a parallel corpus and a supracorpora database of connectives. Based on the well-known statement that LSRs can be explicitated by adding connectives in the translation, it is argued here that through selecting pairs in which fragments where a connective is used to express an LSR in the translation correspond to those containing any of the translation stimuli standard for this connective in the source language, it is possible to get an array of contexts in which this LSR is implicit in the source text (or expressed by means other than connectives). This method is then applied to study the French causal connectives car, parce que and puisque using a Russian-French parallel corpus. The corpus data are analysed to obtain information about LSRs particularly about cases where the causal LSR in Russian is implicit, as well as about the use of causal connectives in French. These results are used to show that the method proposed allows to quickly create a representative array of contexts with implicit LSRs, which can be useful in both text analysis and in machine learning.

This study presents experimental investigations into blade suction surface boundary layer flow in a multistage axial flow compressor. The experiments were focused on the third stage of the 4-stage Low Speed Research Compressor (LSRC) at Cranfield University. Measurements within the boundary layer were obtained using a hot wire probe. This was traversed normal to the blade surface at small increments, capturing the unsteady velocity profile within the boundary layer. Detailed boundary layer flow measurements covering most of the stator suction surface were taken and are described using time mean and ensemble averaged velocity profiles. Turbulence intensity in the boundary layer flow on the blade suction surface is also discussed. A strong wake-induced strip zone due to passing wake disturbances are generated at midspan near the blade leading edge at rotor blade passing frequency. Corner separation was observed at the tip region near the trailing edge. Normalized velocity profiles in this region show no variation in time.

This paper presents results from tests of two stators, one conventional and one with end-bends, operating at low-speed in the buried stage environment of the Cranfield, 4-stage research compressor (LSRC). The aerofoil velocity distributions are modelled on those of a high speed, 10 stage, high pressure compressor with ‘supercritical’ blading, and the stators were cantilevered with clearances of 1.8% of annulus height. The test results are compared with predictions from the Moore Elliptic Flow Program (MEFP) which solves the full, three-dimensional, Navier-Stokes equations with a pressure correction algorithm. The calculation results capture the essential physics of the viscous flow in these two bladerows. The calculated deviations agree well with experimental data across the blade spans, including the near hub-region, which is dominated by the clearance flow. The calculated, radial profiles of loss are in reasonable agreement with experiment, although the magnitude of loss is over-predicted.

The Longitudinal Study of Indigenous Children (LSIC; also called Footprints in Time) is the only longitudinal study of developmental outcomes for Aboriginal and Torres Strait Islander children globally. Footprints in Time follows the development of Australian Aboriginal and Torres Strait Islander children to understand what Indigenous children need to grow up strong. LSIC involves annual waves of data collection (commenced in 2008) and follows approximately 1,700 Aboriginal and Torres Strait Islander children living in urban, regional, and remote locations. This LSIC Primary School report has been produced following the release of the twelfth wave of data collection, with the majority of LSIC children having completed primary school (Preparatory [aged ~5 years] to Year 6 [aged ~12 years]). Primary schools play a central role in supporting student learning, wellbeing, and connectedness, and the Footprints in Time study provides a platform for centring Indigenous voices, connecting stories, and exploring emerging themes related to the experience of Indigenous children and families in the Australian education system. This report uses a mixed-methods approach, analysing both quantitative and qualitative data shared by LSIC participants, to explore primary school experiences from the perspective of children, parents and teachers. Analyses are framed using a strengths-based approach and are underpinned by the understanding that all aspects of life are related. The report documents a range of topics including teacher cultural competence, racism, school-based Aboriginal and Torres Strait Islander education activities, parental involvement, engagement, attendance, and academic achievement.
