Full textAbstract:
The analysis of the origins of the Lithuanian SSR KGB activity and relations with political government helps to understand this institution and does not only bring better understanding of this structure but also contributes to the knowledge of the Soviet totalitarian regime and policy in Lithuania. It is also important to show that KGB was not a secret service of the type analogous to secret services in the West, which pursued intelligence and counter-intelligence functions. Functions of soviet secret service were different from others secret services and this was also determined by specific of soviet system and aims of communist party.
The main aim of the dissertation to prove that the Lithuanian SSR KGB was an institution primarily engaged in ideological and political rather than solely repressive tasks. It is also analyses impact of communist ideology and communist party on the KGB activities, by displaying its relations with the Communist party, Council of Ministers of the Lithuanian SSR, the Supreme Council of the Lithuanian SSR and the Soviet army which would lead to the conclusion on the influence of the Lithuanian SSR KGB to domestic political processes. The dissertation also attempts to enumerate and describe the fields of activity and methods of the Soviet security service that would reflect the ideological and political aspects of its activities.
Dissertation is consisting of three parts. In a first part the main tendencies and changes in KGB activities after 195...

Taip pat būtina parodyti, kad KGB nebuvo tokia slaptoji tarnyba, kaip analogiškos Vakarų valstybių slaptosios tarnybos, vykdančios žvalgybos, kontržvalgybos funkcijas. Jos veikla bei metodai skyrėsi nuo kitų slaptųjų tarnybų, kas irgi buvo nulemta sovietinės sistemos ir komunistų partijos uždavinių. Disertacijos santraukoje pristatoma komunistinės ideologijos ir komunistų partijos įtaką LSSR KGB veiklai, atskleidžiant jos santykius su LSSR MT, LSSR AT, tarybine armija, kas leistų spręsti, kokią įtaką LSSR KGB darė šalies vidaus politiniams procesams. Taip pat darbe įvardijamos sovietinio saugumo veiklos sritis ir metodus, kurie atspindėtų jos veiklos ideologinius ir politinius aspektus. Disertacija susideda iš trijų dalių. Pirmoji dalis bendrais bruožai apibūdina KGB raidos tendencijas, akcentuojant pokyčius, įvykusius po 1954 m. Antroje dalyje pristatomi LSSR KGB politiniai aspektai, kurie atsiskleidžia per LSSR KGB santykius su LKP CK, LSSR Ministrų Taryba ir Aukščiausiąja taryba bei tarybine armija. Trečioje dalyje apibūdinama kaip komunistinė ideologija, vidaus ir tarptautiniai įvykiai, procesai įtakojo KGB veiklą ir jos pokyčius. Taip pat įvardijamos KGB persekiojamos visuomenės grupės bei priežastis, kas nulėmė KGB išskirtinį dėmesį joms. Apibūdinami KGB veiklos... [toliau žr. visą tekstą]

O Feixe Gaussiano (FG) é uma solução assintótica da equação da elastodinâmica na vizinhança paraxial de um raio central, a qual se aproxima melhor do campo de ondas do que a aproximação de ordem zero da Teoria do Raio. A regularidade do FG na descrição do campo de ondas, assim como a sua elevada precisão em algumas regiões singulares do meio de propagação, proporciona uma forte alternativa na solução de problemas de modelagem e imageamento sísmicos. Nesta Tese, apresenta-se um novo procedimento de migração sísmica pré-empilhamento em profundidade com amplitudes verdadeiras, que combina a flexibilidade da migração tipo Kirchhoff e a robustez da migração baseada na utilização de Feixes Gaussianos para a representação do campo de ondas. O algoritmo de migração proposto é constituído por dois processos de empilhamento: o primeiro é o empilhamento de feixes (“beam stack”) aplicado a subconjuntos de dados sísmicos multiplicados por uma função peso definida de modo que o operador de empilhamento tenha a mesma forma da integral de superposição de Feixes Gaussianos; o segundo empilhamento corresponde à migração Kirchhoff tendo como entrada os dados resultantes do primeiro empilhamento. Pelo exposto justifica-se a denominação migração Kirchhoff-Gaussian-Beam (KGB). As principais características que diferenciam a migração KGB, durante a realização do primeiro empilhamento, de outros métodos de migração que também utilizam a teoria dos Feixes Gaussianos, são o uso da primeira zona de Fresnel projetada para limitar a largura do feixe e a utilização, no empilhamento do feixe, de uma aproximação de segunda ordem do tempo de trânsito de reflexão. Como exemplos são apresentadas aplicações a dados sintéticos para modelos bidimensionais (2-D) e tridimensionais (3-D), correspondentes aos modelos Marmousi e domo de sal da SEG/EAGE, respectivamente.
The Gaussian Beam (GB) is an asymptotic solution of the elastodynamic equation in the paraxial vicinity of a central ray, which approaches better the wave field than the standard zero-order ray theory. The GB regularity in the description of the wave field, as well as its high accuracy in some singular regions of the propagation medium, provide a strong alternative to solve seismic modeling and imaging problems. In this thesis, i presenty a new procedure for pre-stack depth migration with true-amplitude, combining the flexibility and robustness of Kirchhoff migration type using superposition of Gaussian beams to represent the wave field. The proposed migration algorithm comprises in two stacking process: the first is the beam stack is applied to subsets of seismic data multiplied by a weight function defined such that stack operator has the same formulation of the integral of the Gaussian beams superposition; the second is a weighted diffraction stack by means of the Kirchhoff type integral having as input the GB stacked data. For these reasons it is called Kirchhoff-Gaussian-Beam (KGB) migration. The main characteristics that distinguish the KGB migration, during the first stage stacking, with other migration methods that also use the theory of Gaussian beams, is the use of the first Fresnel zone projected to limit the width of the subset of seismic traces (beam) using a second-order approximation of the reflection travel time. Examples are shown for applications on two-dimensional (2-D) and three-dimensional (3-D) synthetic seismic data, respectively, to the models Marmousi and SEG/EAGE salt dome data sets.

Full textAbstract:
This thesis examines the relationship between the security service of East Germany and its allies in the Soviet Union and Czechoslovakia during the Cold War, from 1948–89. My use of international history to analyse intelligence-sharing takes us beyond the hierarchical models that typically characterise collaboration and challenge any notion that peripheral Warsaw Pact states were in awe of the Moscow centre. Instead I show that the services were mutually constructed. I analyse how the East German Ministry for State Security (Stasi) sought to cooperatively establish structures to govern intelligence-sharing processes with the Soviet Committee for State Security (KGB) and the Czechoslovakian State Security Service (StB), so that domestic security needs were balanced with the broader alliance’s objectives for collaboration. The tension between national interests and transnational obligations was felt acutely in East Germany and Czechoslovakia. I examine how such tensions were reconciled and, conversely, the effects of failed reconciliation efforts in order to understand the complexities of intelligence collaboration. My research predominantly addresses these questions in relation to the transfer of foreign intelligence. This approach leads me to new sites of intelligence diplomacy as I examine East German diplomacy in the developing world, particularly Zanzibar, and invites reconsideration of old themes, including the Stasi’s role in the 1983 War Scare.

Full textAbstract:
After having reached a level of influence unmatched by any other element of Soviet government under Stalin and Beria, the security organs of the Soviet Union proved difficult to tame. While it has been argued that the KGB was made subservient to the Communist Party of the Soviet Union after the ascent of Khrushchev in the late 1950's, this essay will attempt to show that the security police apparatus was able to maintain a high level of prominence and even autonomy throughout the history of the Soviet Union and beyond. While it may have appeared that the organs were under constraints during periods of unchallenged leadership, the lack of a legislative definition of the KGB's role made the possibility of a coup or putsch a constant threat. During periods of instability, particularly those surrounding the succession struggles, the KGB was able to act independently and was highly influential as to the outcome of these contests. In the latter years of the Soviet era, efforts to alter the system in order to avoid the excesses of previous years revealed the organs to be highly adaptable and cognizant of the need to change to avoid being excluded from the political decision-making process. Through an assessment of the various succession struggles and efforts to place the organs within the confines of legality, the political power of the KGB may be better understood, and placed in a historical perspective side by side with its post-Soviet counterpart, which too is shown to have survived recent upheavals.

Full textAbstract:
This thesis is about a remarkable experience lived through by Latvian émigrés in the mid-1950s. They were the targets of a Soviet repatriation campaign, operated by the KGB, which not only envisioned their repatriation to the Soviet Latvian homeland, but also anticipated the destruction of their émigré society as they knew it. The purpose of this thesis is to portray and analyze this repatriation campaign and the émigré Latvian reactions to it. By looking at the activities of the Committee For Return to the Motherland in East Berlin, the contents of the Latvian language repatriation newspaper Par atgriešanos Dzimtenē (For Return to the Motherland), and the reactions to the campaign in contemporary émigré press, this study shows how highly developed strategies and tactics were implemented in order to elicit certain behaviors from émigrés, and how émigrés advanced their own counter-strategies to offset the effects of the campaign. More specifically, this study examines the standardized narratives in Par atgriešanos Dzimtenē that were meant for émigré self-identification and emulation. This thesis proposes that the repatriation campaign was a highly complex Soviet propaganda effort. The publicly announced goal of repatriation included several parallel goals, aims, and purposes and encompassed many types of activities. Above all, deception was used to cover the actions undertaken against émigrés and to mislead host country governments and agencies. This thesis concludes that notwithstanding the Soviet superiority in organization and resources, a small, unprotected, and internally divided community could withstand the concerted efforts of Soviet propaganda if the group’s sense of mission was sufficiently strong and firm.Denna avhandling behandlar de lettiska flyktingarna från andra världskriget och deras erfarenheter av ofrivilliga kontakter med Sovjetlettland vid mitten av 1950-talet, då flyktingarna blev måltavla för en sovjetisk repatrieringskampanj. Målet för denna kampanj var repatriering, dvs att få flyktingarna att återvända till hemlandet, det av Sovjet ockuperade Lettland. Ett annat mål var att splittra flyktingarnas sammanhållning. Avhandlingen beskriver och analyserar den sovjetiska repatrieringskampanjen och de lettiska flyktingarnas reaktioner. Studien bygger på källmaterial från kampanjverkamheten Committee For Return to the Motherland, som hade sin bas i Östberlin, samt från artiklar i den lettiskspråkiga tidskriften Par atgriešanos Dzimtenē (For Return to the Motherland) som riktade sig till de lettiska flyktingarna. Flyktingarnas reaktioner studeras genom en rad lettiska tidningar som utgavs i Väst. Min avhandling visar hur väl utvecklade strategier användes i syfte att framkalla önskade reaktioner från flyktingarna, samt vilka motåtgärder flyktingar själva utvecklade mot repatrieringskampanjen. Mer specifikt analyseras standardberättelser i Par atgriešanos Dzimtenē som var avsedda för flyktingarnas självidentifiering och igenkännande. Avhandlingen pekar på att den sovjetiska repatrieringskampanjen var en mycket komplex propagandaverksamhet. Utöver det offentligt tillkännagivna kampanjmålet fanns flera parallella målsättningar och avsikter som omfattade en stor mängd skiftande aktiviteter. En strategi som användes aktivt var vilseledning, bl a för att dölja verksamheter riktade mot flyktingarna, och för att förvilla statsledningar och myndigheter i de nationer där flyktingarna vistades. Avhandlingens slutsats är att trots den sovjetiska överlägsenheten i organisation och resurser kunde en liten oförsvarad och inom sig splittrad lettisk gemenskap motstå de samordnade ansträngningar från den sovjetiska propagandan.

Collier, Jonathan. "The story of the Berlin Tunnel: What the operations narrative teaches us about covert conflict in an ongoing Cold War." Digital Commons @ Butler University, 2018. https://digitalcommons.butler.edu/grtheses/501.
Full textAbstract:
Operation Gold (1953-56) was a collaborative covert operation between the American CIA and British SIS. The two major objectives: firstly, rebalance the state of affairs in covert activity, which the KGB had been dominating heading into the 1950s. Secondly, gain more detailed, valuable information on the state of Soviet forces throughout Europe and gain prior warning of possible information. The technological nature of the operation marks it as the beginning of a move away from traditional espionage. Understanding the narrative of Operation Gold establishes a firm foundation on which to address the development of covert activity into the modern day. Key elements of the story of the Berlin Tunnel serve to tie this lesser known operation to modern concerns of privacy, personal data, and covert involvement in international affairs. While unravelling the truest narrative of the planning and implementation of the operation, this thesis integrates substantial events, groups and people which shape the role of the Berlin Tunnel in understanding covert conflict. Further consideration is also given to how this operations legacy unfolded and the role of the media in understanding events in this separate sphere. Lessons about the covert sphere not only address a sub-narrative of 1950s Cold War but reach conclusions pertinent to the 21st century.

Full textAbstract:
Bakgrund: Efterfrågan på tidig fosterdiagnostik har ökat bland blivande föräldrar. KUB är den vanligast förekommande fosterdiagnostiska metoden men är inte diagnostiserande utan kalkylerar en sannolikhet för huruvida trisomi 13, 18 eller 21 föreligger. Detta är kvinnorna inte alltid medvetna om, varför förberedelse och noggrann information är viktigt. Denna studie utfördes därmed för att belysa kvinnors upplevelser relaterat till genomfört KUB. Syfte: Att beskriva kvinnors upplevelser relaterat till genomfört KUB. Metod: Kvalitativ innehållsanalys med induktiv ansats användes. 10 trådar från Internetforumet Familjeliv.se och 12 bloggar hittades under datainsamlingen och låg till grund för dataanalys. Resultat: Analysen mynnade ut ett sammanfattande tema: KUB ses som en möjlighet att bekräfta graviditeten men leder till varierande känslor som barnmorskor måste stödja på ett förtroendefullt sätt. De mest framträdande känslorna som beskrevs relaterat till KUB var oro och rädsla. Barnmorskor upplevdes inte ge det stöd som behövdes. Konklusion: KUB ses som ett sätt att bekräfta graviditeten. För att minska oron behöver barnmorskor ge individanpassad information till kvinnorna. Kvinnors oro relaterat till KUB tenderar att grumla graviditeten och kvarstå lång tid framöver.Background: The demand on prenatal diagnosis increases among expecting parents. CUB is the most common method for the matter but doesn’t provide any diagnosis. CUB only calculates the probability of a fetus with trisomy 13, 18 or 21. Women aren’t always aware of this. Hence, careful preparations and information are necessary. This study was performed to enhance knowledge in women’s experiences in relation to have undergone CUB. Aim: To describe women’s experiences related to having undergone CUB. Method: A qualitative content analysis with an inductive approach was used. Internet was used for data collection. This collection resulted in 10 threads from bulletin board Familjeliv.se and 12 blogs which became the base for data analysis. Result: The analysis resulted in one theme: CUB is seen as an opportunity to confirm the pregnancy but leads to mixed feelings which the midwives need to support in a trustful way. Anxiety and fear are the most common emotions mentioned among women who have undergone CUB. Women felt that midwives didn’t always provide enough information or the requested information. The encounters with midwives during CUB were described as stressful and even unpleasant. Conclusion: CUB is seen as an early way to confirm the pregnancy. To reduce the anxiety, midwives need to give individualised information. Anxiety tends to obscure the pregnancy and remain a long time.

Efter många olika teorier om hur bas, volym och känsla skulle kunna bestämmas i Arduinon bestämdes slutligen att de skulle bero av olika frekvensintervall; basen i 50-250 Hz, volymen i 500-2000 Hz och känslan i 2000-4000 Hz. Basen förflyttar mönstret framåt, volymen bestämmer ljusintensiteten (mellan 50% - 100% av max) och känslan avgör vilket av 6 mönster som aktiveras.

Full textAbstract:
The main thesis of this dissertation is that Jezebel is a primary character in 1 Kgs 16 – 2 Kgs 10. This may be observed both in the so-called Elijah and Elisha cycles. One of the main purposes, if not the purpose, of the stories contained within the Elijah cycle is to enhance the polemic against Jezebel and against the Baal cult which had been introduced by her, and not merely to convey events from Elijah‘s ministry. The choice of the characters and details revealed about their background indicate that the Elijah cycle is only partially concerned with the prophet, while it is directed importantly also against the queen and Baal. Elisha‘s ministry follows that of Elijah. His cycle prepares the reader for the punishment of Jezebel by revealing different details of the final moments of the queen‘s life and the events surrounding her death. Even though the reader will find only two direct references to the queen in 2 Kgs 2-8, the text sheds some light on the queen, her character and her death. The narrative also introduces new characters whose role is to be a foil or a contrast to the queen. The thesis, then, argues that Jezebel is a primary character in the narrative of the middle part of the Books of Kings. It must be said, however, that many elements of the argument against Jezebel operate on the narrator‘s, and not on characters‘, level. Besides a few direct references to Jezebel and to her activities, she herself quite often remains absent from the stage. It is only when one raises one‘s sights from the characters‘ to the narrator‘s perspective that he or she may notice abundance of allusions, prefigurations, comparisons, use of foils, and other devices that enhance the argument against the queen and make her a primary character in 1 Kgs 16:29 – 2 Kgs 10.

Full textAbstract:
This thesis deals with the fabrication and the characterization of periodically-poled crystals for use in lasers to generate visible and UV radiation by second-harmonic generation (SHG) through quasi-phasematching (QPM). Such lasers are of practical importance in many applications like high-density optical storage, biomedical instrumentation, colour printing, and for laser displays.
The main goals of this work were: (1) to develop effective monitoring methods for poling of crystals from the KTiOPO4 (KTP) family, (2) to develop useful non-destructive domain characterization techniques, (3) to try to find alternative crystals to KTP for easier, periodic poling, (4) to investigate the physical mechanisms responsible for optical damage in KTP. The work shows that the in-situ SHG technique used together with electro-optic monitoring, makes it possible to obtain reliable, real-time information regarding the poling quality over the whole crystal aperture during the electric-field poling process. Using this combined monitoring method, both KTP and Rb-doped KTP (RKTP) crystals were successfully poled. By comparing these two crystals, we found that a low-doped KTP has a substantially reduced ionic conductivity and, thus, a high-quality periodic poling can be obtained without otherwise affecting the properties of the crystal. RKTP is a good alternative candidate to KTP for poling purpose. We have also shown that Atomic Force Microscopy (AFM) is an informative tool for investigating domain nucleation, growth, and merging. Furthermore, we have demonstrated a simple technique for 3D characterization of QPM samples. It utilizes a group-velocity mismatched, type-II SHG of femtosecond pulses for layer-by-layer monitoring of the effective nonlinearity along the propagation direction of the beam. The quality of these crystals was finally reflected in a number of SHG experiments with a variety of laser sources. High energies and high efficiencies were thus demonstrated using CW, mode-locked and Q-switched lasers. Gratings with pitches smaller than 3 µm, were demonstrated for first-order UV generation. Type-II QPM SHG was demonstrated as a technique for reducing the fabrication constraints.
High intensity light in the visible and the UV leads to modification of the material properties and, eventually, to optical damage. In KTP and its isomorphs, the first sign of material change is an optically-induced absorption. We have used thermal-lens spectroscopy with a common-path interferometer for high-sensitivity measurements of green light-induced infrared absorption dynamics in single-domain and periodically-poled KTP (PPKTP). The saturated, green light-induced absorption has been shown to be consistently higher in periodically-poled crystals, and is attributed to the creation of stoichiometric and interstitial defects in the crystals during the poling process. Finally, irreversible bulk damage thresholds in PPKTP have been determined for pulsed frequency converters. As the characteristics of optical damage are closely related to the material quality, this investigation can provide useful information for crystal manufactures and will help to optimise the crystal growth conditions.

Full textAbstract:
Dans cette thèse, en suivant les travaux initiés par V. Drinfeld, poursuivis par B. Enriquez, puis par ce dernier, D. Calaque et P. Etingof, nous étudions la connexion KZB elliptique cyclotomique (ellipsitomique en plus court) universelle, associée à l’espace de modules des courbes elliptiques avec n points marqués et une structure de (M,N)-niveau. La platitude de cette connexion nous permet d’étudier des relations de monodromie, ouvrant la voie à une théorie générale des associateurs ellipsitomiques et des groupes de Grothendieck-Teichmüller qui lui correspondent, que l’on dégage via l’utilisation du formalisme des opérades (et certaines de leurs variantes) en nous basant sur les travaux de B. Fresse à ce sujet. D’une part, ce formalisme nous permet par ailleurs d’étudier la structure des associateurs en genre supérieur. D’autre part, l’associateur KZB ellipsitomique nous permet de dégager une théorie des valeurs multizêta elliptiques en des points de torsion, dont on démarque quelques unes de leurs premières propriétés du type associateurs. On commencera par mettre en place la machinerie opéradique nécessaire pour définir les associateurs ellipsitomiques en partant tour à tour de la situation déjà connue en genre 0, puis de celle en genre 1 et ensuite de leurs variantes cyclotomiques. Enfin, grâce à ce formalisme, nous dégagerons une définition des associateurs en tout genre. Ensuite, nous entrerons dans le détail de la construction de la connexion KZB ellipsitomique universelle, en premier temps sur l’espace de configurations (M,N)-décorées d’une courbe elliptique puis sur les espaces de modules des courbes à niveau, nous la lieront à sa version réalisée via l’utilisation des algèbres de Hecke doublement affines et des r-matrices classiques dynamiques. Pour finir nous présenterons les applications de cette construction, à savoir : formalité de certains sous-groupes de tresses sur le tore, l’associateur KZB ellipsitomique, valeurs multizêta elliptiques en des points de torsion ainsi qu’une application en représentations d’algèbres de Cherednik cyclotomiquesIn this thesis, following the work initiated by V. Drinfeld and pursued by B. Enriquez, then by the latter together with D. Calaque and P. Etingof, we study the universal twisted elliptic (ellipsitomic in short) KZB connection, associated to the moduli space of elliptic curves with n marked points and a (M,N)-level structure. The flatness of this connection allows us to study monodromy relations satisfied by this connection, opening the way to a general theory of ellipsitomic associators and Grothendieck-Teichmüller groups corresponding to them, which is released via the use of the formalism of operads (and some of their variants) basing ourselves on the work of B. Fresse. On the one hand, this formalism allows us to study the structure of associators in higher genus. On the other hand, the ellipsitomic KZB associator allows us to derive a theory of elliptic multiple zeta values at torsion points, from which some of their first associator-like properties are distinguished. We will begin by setting up the operadic machinery necessary to define the ellipsitomic associators starting successively with the genus 0 situation, which is well-known, then the genus 1 situation and their cyclotomic variants. Then, in light of this formalism, we will release a definition of genus gassociators. Next, we will go into the details of the construction of the universal ellipsitomic KZB connection, first over the (M,N)-twisted configuration space of an elliptic curve and then over the moduli space of elliptic curves with a level structure. We will associate this connection to its realized version by means of the use of double affine Hecke algebras and of classical dynamical r-matrices. Finally we will present the applications of this construction, namely : the formality of certain subgroups of the braid group on the torus, the ellipsitomic KZB associator, elliptic multiple zeta values at points of torsion as well as an application in representations of cyclotomic Cherednik algebras

Full textAbstract:
Objectives: Periodontal disease is a chronic inflammation resulting in periodontal attachment loss. Keratinocyte Growth Factor-1 (KGF-1) is upregulated in chronic inflammation and specifically stimulates epithelial cell proliferation by signaling through the epithelial-specific Keratinocyte Growth Factor Receptor (KGFR). First, we examined KGF-1 and KGFR expression and localization in human periodontal tissues. Second, we extended these studies by developing an in vitro mechanical wound model to mimic trauma to the periodontal pocket epithelium and examined ligand independent KGFR activation and cell migration.
Methods: In our study of human gingival tissues, we used immunohistochemistry and laser capture microdissection with RT-PCR to analyze KGF-1 and KGFR expression and localization. To study ligand independent KGFR phosphorylation, KGFR internalization along the wound edge was imaged using immunohistochemical staining and KGFR phosphorylation confirmed using immunoprecipitation with western blotting. Wounding induced oxidative stress was detected using DCFH-DA (2',7'-dichlorofluorescin diacetate) and modulated by pretreatment with an antioxidant. Changes in migration were examined in the presence or absence of pathway specific inhibitors.
Results: KGF-1 protein localized to areas of junctional and basal oral epithelial cells was significantly increased in periodontal pocket epithelium (p<0.01) and oral epithelium (p<0.05) of disease-associated tissues. KGFR localized to the junctional and the parabasal cells of oral epithelium, and was increased in disease-associated pocket epithelium (p<0.05). Laser capture microdissection with RT-PCR confirmedKGF-1 and KGFR were specifically expressed by connective tissue and epithelium, respectively. In our cell culture model, mechanical wounding induced ligand independent KGFR activation. ROS (Reactive Oxygen Species) generation along the wound edge was associated with KGFR activation and scavenging of ROS reduced KGFR phosphorylation. The c-Src family inhibitor, PP1, significantly inhibited KGFR phosphorylation. Functionally cell migration was reduced by PP1 (82.7%), SU5402(70%) and PD98059 (57%).
Conclusions: KGF-1 and KGFR proteins are expressed in health but significantly induced in human diseased periodontal tissues. Microwounding associated generation of ROS mediates KGFR phosphorylation via c-Src kinase signaling and induced wound edge cell migration. Therefore, regulation of epithelial cell behavior associated with the onset and progression of periodontal disease may possibly be mediated by two related but distinct mechanisms. (1) Ligand-dependent activation of KGFR due to upregulation of KGF-1. (2) Ligand-independent activation of KGFR due to chronic microwounding.

Full textAbstract:
Bakgrund Fosterdiagnostik har länge varit etiskt diskuterat, inte minst med den snabba utvecklingen avNIPT(non-invasive prenatal testing) som har skett sedan 2011. Rekommendationer föranvändning av NIPT idag är enbart efter KUB(kombinerat ultraljud och blodprov) som harvisat hög risk för trisomi (1/51 – 1/1000). Användningen av både KUB och NIPT skiljer sigmellan regioner och det finns skilda åsikter kring hur metoderna bör användas. Syfte Syftet med denna studie är att analysera förekomsten av fosterdiagnostik med NIPT och KUBsamt analysera den etiska debatten kring att övergå från KUB till NIPT. Frågeställning 1. Vilken är den historiska bakgrunden till fosterdiagnostik i Sverige? 2. Hur fungerar samt används KUB och NIPT och hur ser den diagnostiskatillförlitligheten ut? 3. Vilka etiskt grundade argument talar för och emot utbyte av KUB till NIPT? Metoder Studien är en hermeneutiskt baserad litteraturstudie där artiklar valts utifrån relevans förfrågeställningarna från sökning på databaserna PubMed och Google Scholar samt från olikamyndigheter som Socialstyrelsen, SBU(statens beredning för medicinsk utvärdering), SFOG(svensk förening för obstetrik och gynekologi) och SMER (statens medicinskt etiska råd). Resultat I debatten kring KUB och NIPT identifierades sex teman. Dessa var kriterier för screening,informerat samtycke, ”det sluttande planet” och vad som upptäcks, ekonomiska aspekter,falskt positivt/negativt resultat och tidigare provtagning och abort. Slutsatser Argument har förts både för och mot att införa NIPT som en första screening. Motståndaretog upp kostnad, en risk för ökad abortfrekvens, mindre informerat samtycke och ”detsluttande planet”, medan förespråkare tog upp bättre tillförlitlighet för NIPT, möjlighet tilltidigare diagnos och abort men även här aspekter kring begränsad autonomi.

Det finns mycket lite forskning om kognitiva funktioner vid UMS, däremot en del på närliggande diagnoser som chronic burnout (CBO) och chronic fatigue syndrom (CFS). Denna forskning visar att kognitiva nedsättningar finns hos drabbade. Kognitiva funktioner är ett komplext system där olika tester mäter olika aspekter. Testresultat kan påverkas av bl. a. ålder, utbildning och intelligens. Forskning pågår för att undersöka om Kognitiva Screeningbatteriet (KSB) kan användas för att mäta kognitiva funktioner vid UMS. Föreliggande studie baseras på testningar med KSB på friska personer i syfte att få en kontrollgrupp för fortsatta studier om personer med UMS. Skillnader i resultat som beror på kön, ålder och utbildning undersöktes också. Den äldsta gruppen, 46-56 år, fick signifikant sämre resultat på Stroop test och Symbol Digit Modalities Test (SDMT). Personer med eftergymnasial utbildning fick signifikant bättre resultat på Minnestestet och SDMT. Fortsatt forskning om UMS är viktigt p. g. a. de samhällskostnader som sjukskrivningar innebär och p. g. a. det personliga lidandet för drabbade personer och deras anhöriga.

Full textAbstract:
In this study I examine the effect of seasonal resource limitation on the behaviour and population dynamics of white-eared kob, Kobus kob leucotis, in the Boma region of the southern Sudan. This population, numbering over 800,000, migrates seasonally between savannah grasslands in areas with low rainfall and ephemerally swamped grasslands in areas with high rainfall. The aims of the study were: (1) to examine whether kob migration tracks ephemeral distributions of food or water resources, (2) to test the hypothesis that the Boma kob population is limited by food availability, (3) to determine if calf production is cued to seasonal peaks in food abundance, and (4) to evaluate the effect of breeding synchrony on lekking behavior and male competition.
Seasonal climatic changes produced pronounced changes in the distribution and abundance of both green forage and water supplies. Dry season migration primarily tracked limited supplies of water. Within the dry season range, kob aggregated at high densities (over 1,000 per km²) in low-lying meadows that supported grass re-growth when little green grass was available elsewhere in the ecosystem. However, southerly movements in the wet season were not explainable by the resource hypothesis, since both food and water were widely distributed during the wet season. I suggest that kob may move southward in order to avoid surface flooding during the wet season.
Kob mortality during the dry seasons of 1982 and 1983 was considerably higher than estimated mortality during the wet season. Unusual rainfall during the dry season of 1982 provided a "natural experiment" to test the food limitation hypothesis. Adult mortality was significantly lower during the dry season of 1982 than during the more typical dry season of 1983. Calf mortality did not vary significantly between years. Adult mortality rates were related to dry season duration. Dry season mortality was related to sub-maintenance food intake and declining fat reserves. The age structure of the kob population in 1983 suggests that large-scale mortality (ca. 40%) occurred in the 1980 drought that immediately preceded this study. These findings support the food limitation hypothesis.
Kob exhibited a 4 month period of calf production during the late wet season, when food availability was highest. As a consequence, females continued lactation through the dry season period of food scarcity. I suggest that kob reproductive phenology may result from an obligatory delay during which females restore their fat reserves prior to calving or selection pressures imposed by predation during the vulnerable post-partum period.
Synchronous breeding in the Boma kob was related to
increased rates of aggression between males and increased color
dimorphism, in comparison to the asynchronous breeding Uganda kob, Kobus kob thomasi. Male aggression served not only to establish dominance relations between males on leks, but also disrupted the mating activities of neighboring males. Young adult males suffered higher age-specific mortality than females, possibly resulting from injuries incurred during strenuous fighting on leks.
In order to analyze the age structure of the kob population, I devised a new method for estimating age-specific mortality rates that is free of the restrictive assumptions that underlie most conventional techniques. The proposed method has somewhat greater sampling variation, but is considerably more robust, than two current methods. Moreover, the proposed method permits calculation of age-specific mortality at frequent intervals during periods of population fluctuation and, under some circumstances, population numerical trends may be directly determined from age structure.Science, Faculty of

Thesis (MSc)--Stellenbosch University, 2015.ENGLISH ABSTRACT: Aquaculture is one of the fastest growing food producing sectors in the world. Over the past few years, aquaculture research has focused on improving rearing protocols and standards for the culture of aquatic organisms. Probiotics are gaining increasing interest as an alternative to antibiotics to improve animal health and welfare. The effects of probiotics on the physiological and biochemical development of the digestive tract of commercially raised Argyrosomus japonicus (dusky kob) larvae were investigated. Two probiotic treatments were compared to a control where the standard rearing protocol was applied. The growth of the larvae and histological development of the digestive tract was studied. The specific enzyme activity of key digestive enzymes was determined. Amylase, trypsin, pepsin, alkaline phosphatase, aminopeptidase N and leucine-alanine peptidase were assayed. The mean growth of the control group of larvae differs from the CSIR and BactoSafe treatment groups (P = <0.001). There were no differences in the histological development between the control and two treatments. The histology did indicate a slight delay in development of the digestive tract when compared to previous studies on dusky kob. No significant differences were observed between the control and treatment groups for any of the enzyme assays. The effect of probiotics on the development of the digestive system of dusky kob larvae could not be definitively described as it was not determined to what extent the probiotics had established in the gut. What the study did conclude was that the enzyme assays need to be refined in order to determine the optimal reaction conditions required for the determination of specific enzyme activity in commercially raised dusky kob.
AFRIKAANSE OPSOMMING: Akwakultuur is een van die vinnigste groeiende voedsel produserende sektore in die wêreld. Oor die laaste aantal jare het akwakultuur navorsing gefokus op die verbetering van grootmaak protokolle en standaarde vir die cultuur van akwatise organismes So het die belangstelling in pro-biotika, as alternatief tot antibiotika ten einde die gesondheid en welsyn van diere te verhoog, vermeerder. Die effekte van pro-biotika op die fisiologies en biochemiese ontwikkeling van die spysverteringskanaal van kommersieel geproduseer Argyrosomus japonicus larwes was ondersoek. Twee probiotiese behandelings is vergelyk met ʼn kontrole (standaard grootmaak protokol). Die groei van die larwes en die histologiese ontwikkeling van die spysverteringskanaal is ondersoek. Die spesifieke ensiem aktiwiteite van die sleutel verteringsensieme was ook bepaal. Amilase, tripsien, pepsien, alkaliese fosfatase, aminopeptidase N en leusien-alanien peptidase was ondersoek. Die gemiddelde groei van die kontrole groep was effe hoër as die van die ander twee behandelings. Daar was geen verskil in histologie van die groepe nie maar die tempo van ontwikkeling vir alle behandelinge blyk stadiger te wees as die wat in vorige studies vir A. japonicus rapporteer is. Geen betekenisvolle verskille is opgemerk tussen die kontrole en die behandelingsgroepe vir enige van die ensiem analises nie. Die invloed van die probiotika op die ontwikkeling van die spysverteringskanaal van die larwes kon nie onomwonde beskryf word nie aangesien die vestiging van die pro-biotika in die spysverteringkanaal nie omskryf is nie. Wat wel gevind was, is dat die analitiese tegnieke rakende die ensieme verfyn moet word ten einde die optimale reaksie omgewings te bepaal wat dit sal moontlik maak om spesifieke ensiemaktiwiteite in die kommersieel geproduseerde A. japonicus te bepaal.

Yang, Youngeun. "The Korean National Ballet (KNB) : moving and making national identity." Thesis, University of Surrey, 2015. http://epubs.surrey.ac.uk/807829/.
Full textAbstract:
The Korean National Ballet (KNB), founded in 1962, is a pivotal, government-funded ballet company which acts as a national representative both domestically and internationally. This thesis investigates how the KNB has contributed to the formation of ‘Korean ballet’, a complex phenomenon interpreted through Homi Bhabha’s concept of post-colonial hybridity as a ‘doubling’ of the Western ballet form which simultaneously resists it through indigenisation. It examines the company’s artistic trajectory and repertoire, and analyses how it translates the codified ballet vocabulary to develop its own distinct movement style. The central concern is to show how such hybridisation enables the KNB to fulfil its role as a national organisation charged with representing Korean identity. While the introduction of ballet into Korea is a classic example of cultural imperialism in Edward Said’s sense, the nineteenth-century Russian ballet tradition, particularly Yuri Grigorovich’s interpretations, has exerted more direct authority, foisting colonial sentiments and demands onto the KNB via its set criteria and conventions. Thus a coloniser/colonised division separates the Russian and Korean ballet fields, as colonialism refers not to a past political system but to present sentiments and strategies inscribed in the process of continuing imperialism. The thesis evaluates how the KNB subverts these colonial demands to appropriate ballet as a legitimate means of articulating Korean identity. In the process, it negotiates various forms of state-led nationalism, supporting and shaping cultural policy by absorbing and transforming indigenous elements to bolster and reshape the national image propagated by the state. Paul Gilroy’s work on camp-thinking provides the theoretical foundation for understanding the political reshaping of national identity, while his reflections on the black diaspora confirm the hybrid cultural space as a new site of identity-formation. Thus the thesis nominates the KNB as a crucial insitution in the development and reshaping of national identity in Korea.

Full textAbstract:
Cette thèse est consacrée à l’étude du potentiel des cristaux biaxes dans le but de réaliser un laser de puissance. Les cristaux biaxes possèdent deux axes optiques ce qui donnent lieu à un effet appelé "réfraction (ou diffraction) conique". Cet effet, connu depuis 1832, est intensé- ment étudié depuis une décennie. Les progrès en croissance et découpe cristalline permettent d’obtenir des échantillons de longueurs et de qualités optiques suffisantes pour observer ce phénomène. L’utilisation de cet effet en cavité laser ayant déjà été réalisée [79, 78], l’objectif de cette thèse fut dans un premier temps de confirmer ces résultats. Ainsi, un système utilisant des cristaux de KGd(WO4)2 (KGW) dopés au Néodyme a été préalablement testé. Ces premiers résultats furent décevants. La stabilité, la qualité de faisceau ainsi que l’efficacité étaient plus que mé- diocres. L’efficacité maximale fut d’environ 40 % contre 74 % dans la publication [77]. Par ailleurs, le faisceau de sortie présentait un profil elliptique indiquant la présence d’une lentille thermique avec un fort astigmatisme. Ainsi, cette orientation, qui devrait être proche d’une direction athermale (ne présentant pas d’astigmatisme d’origine thermique) selon Biswal [10], ne l’est pas dans une cavité laser pour ce cristal. De plus ce laser est très peu stable et difficile à aligner. Les fluctuations importantes de l’efficacité de celui-ci ont abouti à une interrogation quant à la dépendance des propriétés optiques aux alentours de l’axe optique. Ainsi, dans les premiers chapitres de cette thèse, figurent une étude détaillée des principales propriétés optiques d’absorption et d’émission. Les ré- sultats de cette étude montrent que ces propriétés varient non seulement suivant la polarisation mais également suivant l’orientation aux alentours de l’axe optique. Etant donné que l’état de polarisation autour de l’axe optique varie avec l’orientation, les dépendances en orientation et polarisation sont liées. [...] Enfin, un montage innovant a été testé afin d’utiliser la réfraction conique. La puissance de sortie ainsi que l’efficacité de ce montage étaient très faibles, environ 800 mW en sortie pour 4 W de puissance de pompeThis thesis is devoted to the study on the potential of biaxial crystals in order to increase laser output power. Biaxial crystals have two optic axes and an effect called conical refraction (or diffraction) can occur. This effect is known since 1832, and intensively studied since the last decade. Thanks to the progress of crystal growth and crystal cutting, it is possible to have long samples of good optical quality in order to ob serve the conical refraction. This effect has already been used in a laser cavity [79, 78]. The aim of this thesis was to confirm the results previously obtained. Thus, Neodymium-doped KGd(WO4)2 (KGW) crystals, cut along the optic axis, have been tested. These first results were disappointing. Stability, beam quality and efficiency were very low. The maximum efficiency achieved was arount 40% compared to the 74% claimed in publication [77]. Thus, this orientation which should be an athermal direction using the calculation of Biswal [10] shows astigmatism when there is a temperature gradient. Furthermore, this laser being difficult to align with strong intensity fluctuations, rise interrogations about the optical property variations around the optic axis. Thus, in the first Chapters of this thesis a study of those properties around the optic axis is given. It shows a strong variation of the optical properties depending on the polarization and orientation around the optic axis. The study of the refraction along the optic axis helps to understand this complex dependency with the orientation. In a second time, holmium-doped KY(WO4)2 (KYW) crystals have been tested for laser emission at 2 µm. The choice of this ion has been done on several criteria. The first one is that the ISL laboratory is used to work with this wavelength and has a lot of equipment. The second one is that Holmium ions have a small "quantum defect" (pump wavelength 1960 nm and lasing wavelength 2074 nm). This low "quantum defect" limits the dispersion between the pump and lasing wavelengths. This decreases the separation between the optic axes of both wavelengths. Thus, when the pump is aligned for conical refraction the lasing wavelength is also aligned along the optic axis. Thanks to a better setup (with new mechanical parts) the polarization and orientation dependencies of the laser efficiency have been investigated. Up to 3 W of output power with a slope efficiency of 70% has been reached near the optic axis. The doping concentration of the Holmium-doped KY(WO4)2 (KYW) being more appropriated for high power laser, no thermal lens effect has been observed. Furthermore, the first conical refraction laser with a quasi-three-level system has been realized. An efficiency of 50% has been achieved with such a conical refraction laser. Finally, a new innovative setup is proposed using the External Conical Refraction. An output power of 800 mW for 4 W of incident pump power has been reached

Full textAbstract:
Fisheries management regulations for dusky kob Argyrosomus japonicus, an important commercial and recreational fisheries species, have failed and the stock is considered collapsed. It is important to take an ecosystems approach to management which includes understanding the effect of environmental factors on recruitment, abundance and distribution. The distribution of early juveniles (20-150 mm TL) in the wild appears to be restricted to the upper reaches of estuaries at salinities below 5 psu. Food availability could not explain the distribution of early juveniles. The aim of this study was to investigate the role of salinity on the distribution of early juvenile dusky kob (<150 mm TL) by examining physiological responses of juveniles exposed to a range of salinities under laboratory conditions. The hypothesis was that the physiological functioning of early juveniles would be optimised at the reduced salinities which they naturally occur at. The objectives of this study were to investigate the effect of salinity on: i) plasma osmolality; ii) growth, food conversion ratio and condition factor; and iii) gill histology with emphasis on chloride cell size and number. A preliminary study was undertaken to determine whether the use of 2-phenoxyethanol had an effect on plasma osmolality. Juveniles pithed prior to blood sampling were used as the control. Plasma osmolality was not affected by exposure or duration of exposure (2, 4, 6, 8, 10 min) to 2-phenoxyethanol. The ability of teleosts to regulate plasma osmolality over a wide range of salinities indicates their degree of ‘physiological euryhalinity’. Plasma osmolality of juveniles exposed to 5, 12 and 35 psu was measured every two weeks over a total of six weeks. Although juveniles were able to regulate plasma osmolality over the duration of the experiment, plasma osmolality at 5 and 12 psu was significantly lower than in fish maintained at 35 psu. Growth is used as an indicator of the relative energy used for osmoregulation at different salinities, as the energy used for osmoregulation becomes unavailable for growth. A nineweek growth experiment was conducted on juveniles exposed to 5, 12 and 35 psu. Juveniles grew and survived at all three salinities. However, growth of juveniles at 5 psu was significantly lower than at 12 and 35 psu. Other than a significantly greater weight gain at 35 psu relative to 12 psu, there was no significant difference in specific growth and length gain between juveniles at 12 and 35 psu. Food conversion ratio and condition factor at 12 and 35 psu were not significantly different, but food conversion ratio and condition factor at 5 psu was significantly greater and lower than at 35 psu respectively. In fish, gills are considered the major organ involved in osmoregulation. Within the gills, chloride cells are the predominant site of ion exchange which is driven by the Na⁺, K⁺- ATPase enzyme. Gill samples of juveniles exposed to 5, 12 and 35 psu for six weeks were examined histologically using light microscopy. Chloride cells of juveniles maintained at 5 psu were significantly more abundant than in juveniles at 12 and 35 psu. Chloride cells of juveniles at 5 psu were significantly larger than in juveniles kept at 12 psu, but not significantly different to those of juveniles kept at 35 psu. The ability of the juvenile fish to regulate plasma osmolality indicates that they are 'physiologically euryhaline', but the reduced growth and proliferation of chloride cells at 5 psu suggests that energy expenditure for osmoregulation is increased at hypoosmotic salinities. Salinity induced physiological responses could therefore not explain the natural distribution of early juvenile dusky kob and it is proposed that other environmental factors (e.g. temperature) are also important. It is also hypothesised that the high conductivity of an estuary in South Africa, to which our understanding is limited, may negate the effect of reduced salinity. Although freshwater input into estuaries is an important factor, further investigations to explain the distribution and abundance of early juveniles is required to make management recommendations. Dusky kob is also becoming an increasingly popular aquaculture species in South Africa. In this regard, early juvenile dusky kob can be grown at salinities as low as 12 psu without negatively affecting growth and production.

Full textAbstract:
Minera Administradora Cerro SAC cuenta en su unidad con un sistema de bombeo de
aguas de interior de mina el cual es indispensable para extraer el agua drenada en sus
labores. La naturaleza del sistema hace que se sobre exijan los equipos ocasionando
paradas de operación reiteradas que conllevan al riesgo de inundación de la mina,
pudiendo esta terminar en cuantiosas pérdidas materiales, pérdidas humanas, y la
paralización de operaciones en la mina, además de significar cuantiosos gastos en
mantenimiento correctivo.
El presente trabajo tiene como objetivo detectar la causa raiz en uno de los
componentes que ocacionan las paradas de las bombas que operan, con el fin de
reducir el riesgo que esto implica. El componente se elige entre todos por su mayor
inferencia en la repetición de las paradas del equipo, siendo seleccionado el perno que
va roscado en el extremo del eje de la bomba y que sujeta al impulsor de la misma.
La metodología que se aplica consiste en la recolección de data histórica acerca de las
ocurrencias de mantenimiento correctivo, a partir de lo cual se selecciona el
componente y se recuperan 2 muestras falladas (nombradas como perno 2 y perno 3)
a las cuales se les practica inspección visual, ensayos de dureza, metalografía y
análisis químico, ademas del levantamiento de la historia previa a la falla de cada
elemento. El resultado se compara con las características del perno descrito por
fábrica, hallándose que el material no corresponde al descrito por fábrica.
Finalmente se realiza la evaluación de resultados, con lo cual se concluye que ambos
pernos fallan por fatiga y que la causa raiz es el material empleado en los pernos que
difiere del especificado por fábrica.Tesis

Full textAbstract:
The dusky kob, Argyrosomus japonicus, is an emerging commercial marine aquaculture species in South Africa. Attributes such as market acceptance, fast growth rates, tolerance to sibling density, acceptance of pelleted feed and adaptability to intensive aquaculture conditions make it a good candidate. Feed, the largest running cost in most aquaculture operations, is a limiting factor in dusky kob production as its nutritional requirements are not well understood. The present project formed part of a research program to develop a locally produced, least cost and sustainable feed that will support the growth and health of dusky kob. The approximate protein and energy requirements for kob fed formulated feeds have been established in earlier research, but the ability of kob to utilize carbohydrates as an energy source has not previously been investigated. The aim of this study was to determine the efficiency of dusky kob to utilize graded levels of carbohydrate (pregelatinized maize starch - PGMS) in pelleted diets. The research objectives were to determine the effect of dietary carbohydrate levels on:i) growth and feed utilization; ii) post prandial blood glucose levels; and iii) general fish health, gut bacterial composition and liver glycogen content of juvenile dusky kob. Hatchery reared juvenile dusky kob (5 g) were acclimatized in a recirculating experimental aquaculture system at the Department of Ichthyology and Fisheries Science at Rhodes University. They were fed trout crumble starter feed for three weeks before the start of the feeding experiment. Five diets containing 4.1, 8.2, 16.4 and 24.6% carbohydrate, hereafter referred to as 4.1C, 8.2C, 16.4C and 24.6C respectively, were formulated with pregelatinized maize starch as a carbohydrate source and fishmeal as the main protein source. Fish were fed these diets twice daily at 3.85% body weight per day for three months. Specific growth rates and feed conversion rations differed significantly between the four dietary treatments. Growth rate increased with increasing carbohydrate up to 16.4%, after which a significant decline was observed. Diet 16.4C produced the highest specific growth rate (SGR) of 1.84 ± 0.05% body weight/day, and the lowest feed conversion ratio of 1.28 ± 0.08. While the lowest specific growth rate and highest feed conversion ratio of 0.79 ± 0.05 and 2.14 ± 0.13 respectively, were found for diet 24.6C. A third order polynomial regression, using SGR, determined the optimum carbohydrate inclusion for dusky kob to be 16.72%. The general structure of the liver was similar between all fish fed the dietary treatments and all fish liver samples displayed a certain degree of lipid vacuolization of the hepatocytes. Evidence of starvation was observed in the livers of fish fed diet 24.6C. However, no differences in the amount of liver glycogen were observed. Gut bacterial composition did not differ among the different diets or between the different sections of the gut. Differences were however observed in the diversity of the bacterial community structure at the start (when they were fed commercial trout feed) and end of the experimental period (after being fed a fishmeal-maize diet). The rate at which glucose was cleared from the blood differed significantly between diets. The low carbohydrate diets (i.e. diet 4.1C and 8.2C) showed a steady rate of glucose removal from the blood over a 48 h experimental period. Sharp increases in blood glucose concentration were observed in diet 16.4C and diet 24.6C, with highest glucose concentrations of 7.18 ± 1.81 and 8.05 ± 2.35 mmol/l respectively, observed 24 h after feeding. The blood glucose concentration of the fish fed diet 16.4C however returned to resting glucose concentration after 48 h, while that of the fish fed diet 24.6C did not. The results demonstrated that the level of dietary carbohydrate inclusion has a significant effect on the growth and health of the fish. The optimum carbohydrate inclusion in dusky kob diets is indicated to be 16.7%, which gave the best growth rate and maximum protein sparing effect without adverse effects on fish health. These findings are important for diet formulation and producing ‘least-cost’ diets for dusky kob farming.

The label “Knowledge Graph” (KG) has been used in the literature for over four decades, typically to refer to a collection of information about real-world entities and their inter-relationships. The proliferation of KGs in recent times opens up exciting opportunities for a broad range of semantic applications such as recommendations. However, unlocking the full potential of KGs in response to the growing deployment requires data platforms to efficiently store and process the content to support various applications.
What began with extensions of relational database systems to store the content of KGs led to the design and development of a number of new specialized data management systems.
Although progress has been made around building efficient KG data management systems, developing high-performance systems continues to pose research challenges. In this research, we studied the efficiency of existing systems for storing and processing KG content. Our results pointed to performance inconsistencies in representative systems across diverse query types. We address this by introducing a polyglot model of KG query processing to analyze each query and match it to the best-performing available systems. Experimental evaluation highlighted that our proposed approach provides consistently high performance.
Finally, we investigated leveraging emerging hardware and its benefits to RDF data management and performance. To this end, we introduced a novel index structure, RDFix, that utilizes Persistent Memory (PM) to outperform existing read-optimized indexes as shown experimentally.

Full textAbstract:
Includes bibliographical references (leaves 27-29).The silver kob, Argyrosomus inodorus, has been identified as a viable species for mariculture in South Africa due to its high demand and market value as well as the necessary biological traits such as high fecundity and fast growth rates. In order for the full scale commercial production to become a reality however, it is important that the environmental conditions required for optimum growth at each phase of the species development are fully understood. Until recently, this sciaenid species was misidentified along with the dusky kob, Argyrosomus japonicus, as Argyrosomus hololepidotus, a fact that resulted in a poor understanding of the life history characteristics of the species and therefore the implementation of a poor management plan. As a result, wild stocks have been heavily over-exploited with spawner biomass-per-recruit ratios estimated at 2.9-12.5% of the pristine level. This study hypothesized that juvenile silver kob would exhibit a preferred temperature when a choice was available to them, and that this preferred temperature might change with age. Two cohorts of juvenile silver kob were acclimatized at 18°C and then subjected to identical temperature preference trials using temperature gradient tanks where the temperature ranged between 16 and 21.5°C as well as to identical isothermal control trials where the temperature throughout the tanks was 18°C. Salinity was kept constant at 35ppt and photoperiod remained 12L: 120 throughout. After a day of acclimation, observations were done over a five day period until the distribution of fish within the tanks had stabilized and that final temperature preferendum could be determined. During this time, dissolved oxygen concentrations were measured continuously to ensure that oxygen did not become limiting but remained above 6.4ppt. Results showed that the juveniles did indeed exhibit a preferred temperature with a range of 16.3 to 17.6°C for the first cohorts, and 16.9 to 18.1°C for the second. This difference between the preferred temperature ranges of the two age classes was found to be significant (p<0.01) by a Mann Whitney U Test. Kolmogorov-Smirnov tests showed no significant difference (p<0.01) between the tanks of the isothermal control trials indicating that there was no shoaling behaviour or individual tank bias affecting the results.

Full textAbstract:
Dusky kob Argyrosomus japonicus is a wide-ranging estuarine-dependent Sciaenid and an important fishery species throughout most of its distribution. It is one of South Africa’s most valuable coastal fishery species. High levels of juvenile exploitation in estuaries and ineffective management regulations have led to stock collapse, highlighting the need to better understand the spatial and temporal aspects of estuarine-dependency and multiple habitat use. Habitat connectivity is a critical property of estuarine-associated fishes and it therefore follows that knowledge of this link is fundamental in understanding population dynamics and the nursery role of estuarine and/or marine habitats. While dusky kob occur in both estuaries and nearshore coastal zones, limited information on connectivity among these habitats exists. The aim of this study is to assess the role of estuarine nursery habitats in the life cycle of the dusky kob by examining multiple habitat connectivity and determining the drivers associated with estuarine use. A total of 96 dusky kob (237–1280 mm total length) were tagged with acoustic transmitters in both the estuarine and marine environments of Algoa Bay, Eastern Cape, South Africa between May 2008 and September 2010. Their movements were monitored using a network of automated data-logging acoustic receivers deployed in the Sundays Estuary, seven neighbouring estuarine habitats, two commercial harbours and various sites within Algoa Bay.
