Sedan motoriseringens intåg i skogsbruket har markskadorna ökat. Framtida klimatscenarier visar på kortare vintersäsonger, samt större mängder nederbörd som ger försämrad bärighet. En branschgemensam miljöpolicy arbetades fram med målsättning att motverka körskador, och få en gemensamsyn på körskador i skogsbruket. En strategi krävdes för att uppnå god miljöhänsyn vid drivningar. SCA Skog arbetade fram sin metod; SED - Skonsam, Effektiv Drivning. Metoden innebär att både i planerings- och drivningsarbetet minimera risken för körskador. Syftet med studien var att undersöka var brister uppstår i SED-metoden. Resultatet visade att 27,4 procent av drivningarna underkändes eftergranskning av traktdirektiv och körloggar. Drivningar med loggade spökslag, påvisade inga förbjudna skotarspår i spökslagen. Markpåverkan kringhänsynsområden och andra känsliga partier har minskat, och fastkörningar med allvarliga körskador som följd sker nästan aldrig i dagsläget genom SED-metoden.

Ma thèse s'inscrit dans l'étude de la physique extragalactique. Pendant mes trois années de thèse j'ai travaillé sur les méthodes d'ajustement de la distribution d'énergie spectrale des galaxies (ou SED fitting) en effectuant un bilan énergétique entre l'émission en ultraviolet et l'émission en infrarouge. A cet effet j'ai très largement utilisé le code CIGALE (Burgarella et al. 2005, Noll et al. 2009) qui permet d'estimer les paramètres physiques des galaxies à partir de l'analyse de leur émission dans des bandes larges et intermédiares de l'ultraviolet au submillimétrique. J'ai procédé pendant ma thèse à des améliorations de ce code en rajoutant des paramètres d'extinction en sortie et j'ai implémenté plusieurs modèles d'émission de noyaux actifs de galaxies pour compléter les modèles existants.En parallèle de l'étude de la méthode de SED fitting avec des données en bandes larges et intermédiaires, j'ai développé la construction originale d'un catalogue de galaxies artificielles, dont le but est de déterminer la fiabilité des paramètres de sortie du code CIGALE et des codes de SED fitting en général. La technique du SED fitting m'a permis d'analyser plusieurs échantillons de galaxies dans l'univers proche et dans l'univers lointain possédant des données multi longueurs d'onde. Pratiquement j'ai travaillé avec des données allant de l'ultraviolet (GALEX) à l'infrarouge lointain avec les téléscopes spatiaux AKARI et Herschel. Les données AKARI couplées à des données ancillaires ont été à la base d'une étude de galaxies de l'univers local pour lesquelles j'ai pu déterminer la quantité d'atténuation.J'ai également travaillé avec les données Herschel en tant que membre des consortiums HerMES et GOODS-H. Dans le cadre du projet GOODS-H j'ai participé à la mise en évidence et à l'étude du "bump" à 2175 A d'un échantillon de galaxies distantes ainsi qu'à la formulation d'une loi d'atténuation pour ces objets. Dans le cadre d'un groupe de travail sur le SED fitting au sein d'HerMES j'ai participé à l'étude d'un échantillon de galaxies avec 0<z<3 afin de déterminer la fiabilité des paramètres physiques estimés par différents codes de SED fitting.Une partie de ma thèse a été consacrée à l'étude de galaxies distantes et lumineuses en infrarouge et à la détermination des caractéristiques physiques de ces objets grâce au code CIGALE. L'étude des paramètres de formation stellaire et d'atténuation ont fait l'objet d'un article, Giovannoli et al. (2011) paru dans la revue scientifique A&A. Toujours dans le cadre du projet HerMES j'ai pu avoir accès aux données du télescope spatial Herschel pour ces objets et donc poursuivre mon étude afin de déterminer l'importance des données infrarouges et submillimétriques pour l'étude des galaxies à haut redshift. / My PhD thesis takes part of extragalactic physics. During three years I have worked on the fit of the spectral energy distribution (SED fitting) of galaxies by doing an energetic budget between the emission at ultraviolet wavelengths and the one at infrared wavelengths. I have extensively used the code CIGALE (Burgarella et al. 2005, Noll et al. 2009) allowing to estimate the physical parameters of galaxies from their broad bands and intermediate bands emission from ultraviolet wavelengths to submillimetric wavelengths. During my thesis I have improved this code by adding output parameters and several templates of active galactic nuclei to those already available.While I have studied the SED fitting technics I have also built original mock catalogues of galaxies to determine the reliability of the output parameters of CIGALE and, more generally, the reliability of parameters estimated by SED fitting codes.I have used the SED fitting method to analyse several samples of galaxies from low redshift to high redshift, with multi wavelength detections. I have used data from the ultraviolet (GALEX) to the far infrared using data from AKARI and Herschel space observatory. I have matched the AKARI data to ancillary data at other wavelengths to study nearby galaxies and determine their dust attenuation quantity. I have used Herschel data as part of HerMES and GOODS-H consortium members. In the framework of the GOODS-H project I have worked on the determination and the study of the so-called ultraviolet bump at 2175 A for a sample of high-redshift galaxies, and on the formulation of an attenuation law for these objects. In the framework of HerMES I have worked with the SED fitting working group to study a sample of galaxies with 0<z<3 to determine the reliability of the physical parameters of these objects estimated with differents SED fitting codes.A part of my thesis was devoted to the study of a sample of distant galaxies, luminous at infrared wavelengths. I have determined the physical parameters of these objects thanks to the code CIGALE. The study of the star formation parameters and the attenuation parameters has been published in Giovannoli et al. (2011), in the scientific journal A&A. With the HerMES project I could have access to Herschel data for these luminous galaxies and pursue my study to determine the importance of far infrared data to study high-redshift galaxies.determine the importance of far infrared data to study high-z galaxies.

Title: The evaluation of functional sitting stability of paraplegics Objectives: The aim of this work is to evaluate the functional stability of paraplegics sitting through tests. Another objective is to determine what is the effect of fourteen days rehabilitation intervention on the sitting patients. Methods: Designed experiment was processed by the form of quantitative research. There were 10 pacients with spinal cord injuries, especially paraplegics included - 5 men and 5 women. The history was detected with the main emphasis on assessment ASIA score. Measurement of unsupported upright sitting was done thanks to the Plantograf V09. It records the current pressure distribution and movement of the center of pressure (COP). Functional T - shirt test was evaluated by using a stopwatch. Probands responded two questions about their current condition after rehabilitation after the output measuring. The therapist rating was included in the results. All data were further processed in Microsoft Office Excel 2007. Results: Measurements confirmed the reliability of both used tests. The t-shirt test can be used as an objective method of assessing functional stability of sitting. Test of unsupported upright sitting measured by Plantografu is also usable. It would be appropriate to set the measuring apparatus...

Thesis (MBA (Business Management))--University of Stellenbosch, 1999. / ENGLISH ABSTRACT: Sasol Technology Engineering Division (SED) is part of the Sasol Group of Companies and was formally established in 1983. The organisation's immediate focus was to render technical and project management support to the operating petrochemical units of Sasol 2 and Sasol 3. During the late 1980's and early 1990's various external drivers appeared that necessitated a review and adjustment to Sasol's strategic direction. Sasol decided to unlock the value in raw materials and embarked on an investment program in major chemical production facilities. With this new drive towards implementing large, multi-million Rand, projects, SED had to re-assess its competencies and focus in order to support this new strategic drive of Sasol. During 1995 an extensive management buy-out (MBO) exercise was concluded whereby most of the technical discipline departments were outsourced. The idea was that all modification and operations support projects be handled by the MBO's. This enabled SED to focus on large projects. With the new strategic direction in place SED launched a Balanced Scorecard (BSG) exercise to convert this strategy into specific goals and communicating the strategy to all employees. This exercise led to the development of a document called the SED Strategic Roadmap. This document explained the goals and interventions required for success until 2003. The review and re-visiting of the SED Strategic Roadmap formed the main focus of this study project. A serious concern identified from the outset was that no realised strategy was drafted before the strategic intent was formalised. Therefore, in order to review the SED Strategic Roadmap a study was done on the realised organisational situation of SED by means of the results of various organisational studies done by consultants. With a realised situation formalised the development and contents of the SED Strategic Roadmap were explained. Following this explanation a broad literature review was conducted to grasp the latest thinking around the management science of strategy. With the realised strategy and theory as background the mere reason for SED's existence was unravelled. A very important finding was that SED should rather focus on improving its operational effectiveness instead of formalising a strategy. SED remains a supporting division that should underline and align itself with the strategic needs of Sasol. For reviewing purposes a "new" set of goals was identified that is closer linked with the purpose of SED. An intervention was allocated to each "new" goal to ensure focused implementation of every "new" goal. A proposal was tabled to conduct and implement the interventions in terms of project-based management, meaning that all interventions are handled as projects with budgets, time spans and specified outcomes. The listed "new" goals serve as an alternative to those in the SED Strategic Roadmap. The "new" goals support the vision of SED and provide the opportunity to excel in improving its operational effectiveness. / AFRIKAANSE OPSOMMING: Sasol Tegnologie Ingenieursdivisie (SED) is deel van die Sasol Groep van Maatskappye en het formeel tot stand gekom in 1983. Die organisasie se onmiddelike fokus was om tegniese- en projekbestuursondersteuning te gee aan die petrochemiese bedryfseenhede van Sasol 2 en Sasol 3. Gedurende die laat 1980's en vroeë 1990's het verskeie eksterne besigheidsdrywers na vore getree wat Sasol genoodsaak het om sy strategiese rigting te hersien en aan te pas. Dit het Sasol tot die besluit gebring om die waarde in rou materiaal te onsluit deur 'n investeringsprogram te loods vir die oprigting van verskeie groot chemiese produksie fasiliteite. Met hierdie nuwe dryf na die implementering van groot, multi-miljoen Rand projekte was SED genoodsaak om bevoegdhede en fokus te hersien om daardeur ondersteuning te gee aan die nuwe strategiese rigting van Sasol. Gedurende 1995 is 'n uitgebreide bestuursuitkoop (MBO) aksie geloods waartydens meeste van die tegniese dissipline departemente uitgekontrakteur is. Die gedagte was dat alle klein modifiserings- en bedryfsondersteuningsprojekte deur die MBOs hanteer moes word. Hierdeur kon SED fokus op groot projekte. Met die nuwe strategiese rigting uitgestippel het SED voortgegaan en 'n "balanced scorecard" (BSG) oefening geloods waardeer die strategiese oogmerke omgesit is in spesifieke doelwitte en na die res van die werknemers gekommunikeer is. Hierdie oefening het gelei tot die ontwikkeling van die SED Strategiese Padkaart dokument. Die dokument beskryf die doelwitte en intervensies benodig vir operasionele sukses tot en met die jaar 2003. Die hersiening en heroorweging van die SED Strategiese Padkaart vorm die fokus van hierdie studieprojek. Vanuit die staanspoor is 'n ernstige bekommernis uitgelig deurdat geen analise gedoen is van die gerealiseerde strategie voordat die strategiese intensie geformaliseer is nie. Derhalwe was dit nodig om eers 'n studie te doen waardeer die huidige, gerealiseerde strategie beskryf kon word. Hierdie studie was gedoen na gelang van die resultate van verskeie organisasiestudies wat deur konsultante uitgevoer is. Met 'n gerealiseerde situasie geformuleer is die inhoud van die SED Strategiese Padkaart verduidelik. Die verduideliking is gevolg met 'n bree literatuuroorsig rakende die wetenskap van strategiese bestuur en die nuutste denke rondom die onderwerp. Met die gerealiseerde strategie en literatuurstudie as agtergrond is die werklike rede vir die bestaan van SED opnuut ondersoek. 'n Belangrike gevolgtrekking wat gemaak kon word is dat SED liewers moet fokus op die verbetering van die organisasie se operasionele effektiwiteit in plaas van die formalisering van 'n strategie. SED bly 'n ondersteuningsdivisie en behoort gerig te wees tot die strategiese behoeftes van Sasol. Vir hersienings doeleindes is 'n "nuwe" stel doelwitte geidentifiseer wat nouer bande het met die rede vir SED se bestaan. 'n Intervensie was toegedeel aan elke "nuwe" doelwit om sodoende gefokusde implementering van elke "nuwe" doelwit te verseker. 'n Voorstel is gemaak om alle intervensies te implementeer in terme van projek-gebaseerde-bestuur. Hierdeur word verwys na die hantering van intervensies as projekte met begrotings, tydskedules en spesifieke verwagte resultate. Die gelyste "nuwe" doelwitte dien as alternatief tot die doelwitte soos beskryf in die SED Strategiese Padkaart. Die "nuwe" doelwitte ondersteun die visie van SED en verskaf die geleentheid om die verbetering van die operasionele effektiwiteit te versnel.

Fientliga företagsförvärv har under en lång tid varit en del av den globala finansmarknaden och är numera inte främmande för de svenska aktörerna. Ett företagsförvärv blir fientligt när bolagets styrelse råder aktieägarna att avslå det framlagda budet. Är budet intressant för aktieägarna, som ofta strävar efter att maximera sin kapitalvinst, kan det dock lätt uppstå en intressekonflikt inom bolaget då styrelsen, till skillnad från aktieägarna, är snarare intresserad av att behålla sin makt och anställning. Detta kan resultera i att styrelsen blir frestad att vidta åtgärder för att förhindra uppköpet.   I samband med fientliga uppköpserbjudanden har det på den amerikanska aktiemarknaden utarbetats en rad försvarsåtgärder som kan vidtas av bolagsstyrelsen i syfte att försvåra eller förhindra ett företagsförvärv. På den svenska aktiemarknaden är vidtagande av åtgärder som har till syfte att förhindra eller försvåra att ett uppköpserbjudande framläggs eller genomförs icke tillåtna enligt 5 kap. 1 §             lagen om offentliga uppköpserbjudanden på aktiemarknaden (LUA). Motiveringen till detta förbud framkommer i bland annat Aktiemarknadsnämndens uttalande AMN 2005:47:”ett offentligt erbjudande anses vara en angelägenhet mellan målbolagets aktieägare och budgivaren, varför målbolagets styrelse inte ska tillåtas försämra förutsättningarna för att ett erbjudande lämnats”. Av denna anledning har styrelsen i ett målbolag som är ett aktiebolag en relativt svag position, då den beslutsfattande makten är hos de enskilda aktieägarna vid exempelvis antagandet av ett framlagt bud och hos bolagsstämman avseende vidtagande av eventuella försvarsmetoder. Dock har det genom AMN:s uttalanden framkommit i en rad praktiska fall att målbolagets styrelse hittat möjligheter att agera och i viss mån kringgå förbudet.   Uppsatsen är en komparativ studie med den svenska och amerikanska rättregleringen i fokus. Paralleller och samband dras även mellan det svenska, europeiska och engelska systemet. Syftet med arbetet är att undersöka svenska företagsledningarnas möjligheter och handlingsutrymme vid tillämpning av internationella försvarsmetoder för att avvärja ett oönskat uppköpserbjudande. I uppsatsen undersöks även de åtgärder som kan vidtas i ett preventivt syfte.   Möjligheten till genomförandet av ett bolagsuppköp är ett nyckelmoment för skapandet av en effektiv värdepappersmarknad där svaga bolag upphör att existera och starka bolag har utvecklings- och tillväxtmöjligheter. Att avgöra vad som stämmer överens med god sed kan dock bli problematiskt, då regleringen på området är oerhört spridd och i viss mån inkoherent. Trots dessa svårigheter har det i praktiken genomförts ett antal företagsuppköp som har visat på att tillämpningen av försvarmetoder är i viss utsträckning möjlig om den går att motivera genom att bolagets eller/och aktieägarnas intressen tillgodoses. Enligt aktiebolagslagen (ABL) är föremålet för aktiebolagets verksamhet att ge vinst till fördelning för aktieägarna. Samtidigt är aktieägarnas förtroende centralt för väl fungerande värdepappersmarknader. En mer omfattande rätt för bolagsstyrelsen i målbolaget att fatta beslut om försvarsåtgärder skulle kunna skada dessa grundläggande ändamål med ABL och den börsrättsliga regleringen. På så sätt skulle en betydligt större makt hos bolagsstyrelsen kunna ha en skadlig effekt, då det är aktieägarnas vinster och förtroende som bör prioriteras. Genom att analysera samspelet mellan de bolagsrättsliga och börsrättsliga principerna och relevanta praktiska avgöranden går det att se att den nationella regleringen är konstruerad på bästa möjliga sätt för att upprätthålla en god sed på den svenska finansmarknaden, trots sina potentiella brister i sammanhanget. / Hostile takeovers have for a long time been a part of the global financial market and are nowadays not an unknown phenomenon on the Swedish stock market. A takeover attempt becomes hostile when the board of directors of the target advises the shareholders to reject the submitted bid. That particular situation can, however, easily become the reason for conflict of interests within the company. The bid can be valuable for the shareholders, who primarily seek ways to maximize their profit at the same time, as the members of the board of directors desire to keep their employment and position within the company. The board can therefore as a result be willing to take action in order to prevent the takeover.   During the mid-20th century, due to a takeover-wave, the American stock market developed a series of defence measures that could be used by the board in order to impede or prevent an acquisition. However, measures that are intended to prevent or impede a takeover offer are prohibited on the Swedish stock market under Ch. 5 § 1 in the Act on Public Takeover Offers. The justification for this prohibition is found in, inter alia, the Swedish Securities Council's (Aktiemarknadsnämnden) statement AMN 2005: 47 where they indicated that a public offer is considered to be a matter between the target company's shareholders and the bidder, why the offeree company should not be allowed to impair the prerequisites for an offer submitted. For this reason, management has a relatively weak position in Swedish corporations, since the decision-making power is not with the board but with the separate shareholders when it comes to accepting a potential bid or the shareholders’ meeting of the corporation when a decision must be made if measures should be enact in order to prevent a bid. However, the boards of directors in some target companies have found opportunities to act and to some extent circumvent the ban posed in the Act on Public Takeover Offers.   The thesis is a comparative study with Swedish and American legal regulations in focus. Parallels are also drawn between the Swedish, European and English systems. The aim is to investigate the ability of the board of directors in Swedish corporations to use different defence methods to fend off an unwanted takeover bid. The paper also examines the measures that can be taken before the bid and as a result have a preventive function.   The possibility of implementing a company takeover is a key element for the creation of an efficient financial market in which weak companies cease to exist and strong companies have development and growth potential. A determination on what actions can be consistent with good practice can be problematic, since the regulations in this area are extremely widespread and somewhat incoherent. Despite these difficulties, the legal practice in this area has shown that the application of the defence methods is to some extent possible if the board of directors focus on supporting the will to defend the company and / or shareholder interests. To give the board of directors extended powers could have a detrimental effect on profits and trust. By analysing the interaction between the principles in company law and securities law as well as some relevant decisions by the Swedish Securities Council, it is possible to see that the Swedish national regulation is designed in the best possible way to maintain good practices on the Swedish stock market despite some shortcomings.

Denna text tar sin utgångspunkt i frågan om moralisk pluralism i dagens Sverige är möjlig. Forskning visar på att en grupp präglad av mångfald kan drabbas av samarbetssvårigheter, men det motsatta är inte garant för ett gott resultat. Enligt Fredrik Gregorius anpassar sig religiösa minoriteter ofta till det omgivande samhällets ide om etik och moral. Denna text undersöker om det finns något som skulle kunna benämnas hednisk etik i Samfundet Forn Seds egen tidning. Källmaterialet består av ett flertal artiklar från #20 respektive #35-36. De teoretiska begrepp som använts är antropocentrism samt universalism, vilka härrör från judisk och kristen etisk idétradition. Materialet har studerats med en metod för argumentationsanalys framtagen av Stephen Toulmin, vilken lämpar sig väl för att lyfta fram implicita antaganden om exempelvis människan. Det huvudsakliga resultatet pekar på att det finns minst två olika typer av hednisk etik en värdeontologisk och en dygdetisk. Båda antas ha sin grund i en föreställning om förnuft och därmed betraktas som universella värden/dygder. Naturen antas dock ha värde och rättigheter oberoende av människan i och med sin helighet, vilket innebär att exempelvis värden som frihet begränsas av naturens existensberättigande. Antropocentrismen är således inte lika framträdande som inom kristendomen och judendomen, men det finns andra beröringspunkter såsom en föreställning om en naturlig lag och att etiken är förnuftsbaserad, dessa likheter sammanfaller dock inte med samtliga judiska/kristna traditioner. / This paper starts with the question whether moral pluralism is possible in Sweden or not. Research shows that a group characterized by diversity is subjected to difficulties in cooperation, but the opposite is not a guarantee for a good result. According to Fredrick Gregorius, religious minorities often adapt to the surrounding societies' idea of ethics and moral. This text investigates if there is something that can be called pagan ethics in the community Forn Seds own newspaper. The source material consists of several articles from #20 and #35-36. The theoretical concepts that have been used are anthropocentrism and universalism, which is derived from Jewish and Christian ethical traditions. The material has been studied with a method of analysis of argumentation formed by Stephan Toulmin, which is suitable for highlighting implicit assumptions. The main result shows that there are at least two different types of pagan ethics, a value ontological and a virtuous theory. Both are assumed to have their foundation in the notion of reason and thus are regarded as universal values/virtues. However, nature is believed to have values and rights independent of humans because of nature's sanctity, which means that values for example, such as freedom, is limited because of the rights of nature to exist. Anthropocentrism is not as prominent as in Christianity and Judaism, but there are points of reference such as a notion of a natural law and that ethics is based on reason, these similarities, however, do not coincide with all Jewish/Christian traditions.

Title: Informing teachers about the importance of correct seating and ergonomic work space. Problem definition: This dissertation addresses Basic and Special School teachers' and Teachers College students' level of awarness about the meaning of Corrected sitting position and their knowledge of suitable ergonomic, educational school furniture and the conditions for achieving the right Corrected sitting position. Reasoning: Children at schools often have problems with corrected sitting and teachers often don't know the aspects of right body-control. They also very often pay no or very little attention to this problem. Corrected sitting position, which is necessary to be applied in schools, is one of the fundamental pre-requisite of right kinetic advancement and creation of premises for school work. Dissertation objectives: Purpose of this dissertation is to find out what is the teachers' level of awareness about the necessity of using Corrected sitting position at schools and aspects of the right body-control and how much they know about the possibilities of using ergonomic educational furniture. Methodology: This dissertation is a analytical study. I work with the findings from questionnaires filled in both by Basic and Special School teachers and Teachers College students. After processing and...

This thesis establishes the basic images of the gazelle in ancient Egyptian art and their meaning. A chronological overview of the categories of material featuring gazelle images is presented as a background to an interpretation. An introduction and review of the characteristics of the gazelle in the wild are presented in Chapters 1-2. The images of gazelle in the Predynastic material are reviewed in Chapter 3, identifying the desert hunt as the main setting for gazelle imagery. Chapter 4 reviews the images of the gazelle in the desert hunt scenes from tombs and temples. The majority of the motifs characteristic for the gazelle are found in this context. Chapter 5 gives a typological analysis of the images of the gazelle from offering processions scenes. In this material the image of the nursing gazelle is given particular importance. Similar images are also found on objects, where symbolic connotations can be discerned (Chapter 6). References to healing and regeneration are found, particularly in relationship to the context of the objects. The gazelle is found in a divine context in a limited material (Chapter 7). A discussion of these sources sees a focus on the gazelle as representative for the desert mountains as the setting for death and rebirth. This relates to the gazelle as a feminine image with a connection to the models of female divinity (Chapter 8).
