Coopération internationale et protection du patrimoine au Laos : analyse du programme UNESCO-Chinon-Luang Prabang à la lumière des Policy transfer studies / International cooperation and heritage protection in Laos : analysis of the UNESCO-Chinon-Luang Prabang program in the light of the policy transfer studies

Sisaykeo, Phimpha 18 December 2015 (has links)
La coopération au développement met en jeu de puissantes forces de changement et de résistance à l’interface de systèmes d’acteurs paramétrés culturellement, économiquement, politiquement et institutionnellement de manières souvent très différentes. Des demandes d’assistance sont émises et des offres de service sont proposées sur des problèmes pour lesquels doivent être bâties des réponses adaptées aux situations pour lesquelles elles ont été sollicitées. Comment se construisent ces réponses ? Comment sont prises en compte les spécificités des acteurs ? Comment sont intégrées les caractéristiques culturelles, économiques, politiques et institutionnelles des partenaires lorsque ceux-ci se retrouvent en situation d’altérité significative ? Comment finalement s’élabore une solution de développement en coopération ? Ce travail propose des éléments de réponse à partir de la coopération à la protection du patrimoine entre Luang Prabang, Chinon et l’UNESCO de 1995 à 2015 et la mobilisation d’un protocole de recherche dont les principaux outils sont empruntés aux analyses en termes de transfer studies. / The development cooperation brings into play powerful forces of change and resistance at the interface of different culturally, economically, politically and institutionally systems of actors. Requests for assistance are emitted and services offerings are proposed on problems for which must be built answers adapted to situations for which they are requested. How are these answers built ? How are taken into account specificities of the actors ? How are integrated the partners cultural, economic, political and institutional characteristics in situation of significant otherness ? Finally, how is a solution of development in cooperation worked out ? This research proposes replies starting from the cooperation to heritage protection between Luang Prabang, Chinon and UNESCO from 1995 to 2015, and the mobilization of a protocol of research whose principal tools are borrowed from the analyses in terms of transfer studies.

Strategic Environmental Assessment Pre-Study of That Luang Marsh : For Sustainable Development in Vientiane Capital, Lao PDR

Olsson, Fredrik January 2010 (has links)
IntroductionLao People Democratic Republic (Lao PDR / Laos) has a population of 5.8 million people and is today one of the least developed countries in Asia. That Luang Marsh (TLM) is the largest remaining urban wetland (2000 hectare) in Vientiane Capital, which historically has supplied wildlife and local people with several eco-services. Some important functions are wastewater treatment, flood control (water storage), and several agricultural and aquacultural services. Due to the flat landscape and the low permeability in soil, the area becomes naturally flooded during the wet season when the water level in the Mekong River is high. All storm water in Vientiane is drained through TLM. There have been several projects in Vientiane aimed to solve the drainage and sanitarian situation. However, the problems have still not been completely solved today. Aim and objectives This Master of Science thesis aims at providing a prestudy for a Strategic Environmental Assessment (SEA), which may be used for creating a full-scale SEA in the future. The main objectives that will be analyzed are: Wastewater treatment in Vientiane. The environmental impact caused by human activity and how it can be reduced in TLM / Vientiane / Mekong River. Sustainable development in Vientiane. The need of SEA in TLM. Flood control in Vientiane. • Agriculture and aquaculture in Vientiane. The WATER Project and New Town Development Project. Socioeconomic overview of Laos / Vientiane. Methodology This thesis is a collaboration between the Swedish university KTH and the Thai university AIT. The student (author of this report) was linked to Dr. Shipin, co-advisor at AIT through Dr. Frostell, supervisor at KTH, and Dr. Berg. A field study was made from October 2008 - December 2008 in Vientiane Capital, Laos. The student has collected information from NGOs, institutions, departments, laboratories, libraries, local people, and Internet in the form of hardcopy literature, electronic documents, e-mail contacts, and interviews. During two days the student had the favour to join a team sent out by WWF for collecting water samples around the marsh. The team consisted of representatives from WWF and the three districts that surround That Luang Marsh. Strategic Environmental Assessment The main purpose of a SEA is to support sustainable decision-making processes in an area. Except from environmental aspects, the SEA also considers socioeconomical aspects. SEAs may differ in terminology and practice between countries and organisations but do usually include stages like preliminary scan, conduction of SEA, preparation of the report, implementation of SEA in PPP (policy, plans, or programmes), and review of the implementation. This report gives a short briefing about how SEAs are produced by CIDA (Canadian International Development Agency) and according to the European Directive. The European Directive is the standard SEA for several European countries. The report does also present the project oriented EIA (Environmental Impact Assessment) Wetland valuation Wetlands may be valuated in different ways. This report explains one method where the valuation is separated into: DUV (Direct Use Value), IUV (Indirect Use Value), OV (Option Value), and NUV (Non Use Value). These are added to TEV (Total Economical Value). WATER Project The WATER project is a response to the environmental and socioeconomical problems that have occurred in Vientiane. Several past projects have been less successful, which have resulted in adverse impact on the society and the ecosystem. The WATER project tries to highlight the wetland values and convince authorities to use CWs (Constructed Wetlands) instead of conventional wastewater treatment plants for treating wastewater. This project will first do five pilot studies in Vientiane. Three will be used for treating domestic wastewater and two for industrial. The project is a part of the Wetland Alliance Programme. Main partners during the project are the government of Lao PDR, WWF Laos, WWF Germany, Wild Fowl & Wetland Trust (WWT). Other involved partners are CORIN, AIT, WFC, CIDA, and Sida. It seems that the authorities will allocate 22 hectares for constructing a CW that will purify Vientiane’s most polluted urban water canal Hong Ke. The WATER Project recommends that even Hong Xeng is included which totally requires 61 hectare CW area. New Town Development Project The New Town Development is a collaboration between the Lao and Chinese government. The plan is to develop the city so it attracts more foreign and domestic investors. 1000 hectares low valued land will be developed for business and 200 hectare will be used for creating an artificial lake aimed for compensating lost wetland area. As a part of the negotiations, the Chinese has already constructed a stadium that was used during the SEA Games 2009. 670 hectare will be developed in TLM, 100 hectare in Dongphosy Forest, and 430 hectare close to the new stadium. The Chinese investors will lease the developed land for 50 years. This may be used for business. When the project period is over, the Lao government have the right to reclaim all developed land without compensation. The Chinese Suzhou City stands as model for the development project in Vientiane. The estimated cost of the project is USD 800-1000 million. Discussion and conclusions Choosing SEA, CEA (Cumulative Effect Assessment), or another strategic assessment method should not be the main issue. As long as the method contributes to a strategic sustainable development and is internationally accepted it may be used for PPPs. The main issue of SEA is not to create a report, but convincing authorities about the importance of sustainable decision-making processes. Factors that may inhibit a sustainable development in Laos are low education, corruption, and greedy investors that devastate the environment for own profit. The laws are in several cases enough but due to the lack of a judicial organization and economical funding the legislative system becomes inefficient. It is difficult to valuate wetlands. The greatest challenge is to valuate OVs and NUVs. OVs are difficult because they are just options. NUVs are based on a subjective estimation because these consider cultural and aesthetical values. A problem with the New Town Development Project is that some vulnerable groups that live in TLM will be forced to live in a resettlement area. These people may have difficulties to adapt to the new environment. It is important that the authorities work extra hard with helping project affected people. Wetland degradation is probably a result of i) intense water pollution (wastewater from households and industries), ii) physical destruction (housing, filling, and artificial drainage), iii) overuse of wetland VI resources, iv) invasions or invitations of new species (golden apple snail). In theory, wetlands may be replaced with modern technology for protecting the city against flooding. One way is to build a cement layer in Houay Mak Hiao River for increasing the drainage capacity. However, because the country has very small economical margins and the hydrological situation is not completely investigated, this could be treated as a risk project. Another problem is that the wastewater capacity will reduce and the biodiversity in the river will be lost. The loss of wastewater treatment needs to be compensated with modern technology. Something needs to be done for increasing the sanitarian situation in Vientiane. This report has compared the benefits of using conventional wastewater treatment plants and CWs. Probably the most reasonable solution is to use a CW for treating the wastewater in Hong Ke while the new centre in TLM uses a conventional wastewater treatment plant. This is an optimal solution because a conventional wastewater treatment plant for treating the water in Hong Ke would require a completely new sewage system, which could become very expensive. Maintaining a conventional wastewater treatment plant is also expensive and requires special trained staff. An easier alternative would be to use CWs for the old part of Vientiane. Because the new centre will be built in a modern style with new infrastructure this part of Vientiane could treat wastewater conventionally. Building a conventional wastewater treatment plant would also save some high-valuated land. Conventional Wastewater TreatmentAdvancedStandardizedQuick turnover timeRequire small spaceCould be more sanitarianProcesses better evaluated Constructed WetlandLong lifetimeEffective in warm climatesNo chemical inputEasy to maintainLow sludge productionAestheticalLess need to change infrastructureLow running cost (flat topography) The author will not decide if Vientiane should develop into a top modern city or remain as a small sized capital as it is today. However, today the situation is unsustainable and something needs to be done. Better organization and planning is necessary for not repeating mistakes that were made during past projects. All decisions have to be based on a non-corruptive process and sustainable thinking. Integrating an environmental and socioeconomical strategy into the future of Vientiane should be of interest for all Laotians. Vientiane is the economical centre of Laos and an increased discharge of polluted water into the Mekong would increase the stress of the important river. A collapse of the biodiversity in the Mekong would strike hard on Laos’ fishing industry and economy. Decisions made today will surely more or less affect people at local, regional, national, and international level in the future. / Inledning Mänsklig aktivitet har på vissa håll resulterat i en allvarlig miljöpåverkan. Laos har en befolkningsmängd på 5,8 miljoner invånare och räknas idag som ett av Asiens minst utvecklade länder. That Luang Marsh (TLM) är huvudstaden Vientianes största urbana våtmarksområde (2000 hektar). Våtmarksområdet bjuder på flertalet ekologiska tjänster som under historiens lopp gynnat både människor och djur. Några av dessa är naturlig vattenrening och översvämningsskydd (vattenlager). Våtmarken bidrar till ett rikt jordbruk och akvakultur. Under regnperioden stiger vattennivån i Mekongfloden så att området naturligt svämmas över. Dräneringen av Vientiane försvåras eftersom landskapet är platt och permeabiliteten i jorden är låg. Huvudsakligen flödar vattnet ut via TLM och floden Houay Mak Hiao innan det når Mekongfloden. Flertalet projekt har försökt effektivisera Vientianes dräneringseffektivitet och minska de sanitära problemen. Dock finns det en hel del kvar att göra. Syften och mål Detta examensarbete är en förstudie till en Strategic Environmental Assessment (SEA). Förstudien skulle kunna utnyttjas till uppbyggandet av en komplett SEA. Huvudområden som undersöks i denna rapport är: Vattenreningen i Vientiane. Den mänskliga miljöpåverkan och hur denna kan lindras i TLM / Vientiane / Mekongfloden. Hållbar utveckling i Vientiane. Behovet av SEA i TLM. Översvämningsskydd i Vientiane. Jordbruk och akvakultur i Vientiane. Projekten WATER Project och New Town Development Project. En socioekonomisk översikt för Laos /Vientiane. Metod Projektet är ett samarbete mellan det svenska universitet KTH och det thailändska universitet AIT. Författaren till denna rapport, Fredrik Olsson är mastersstudent på KTH och har genomfört och utvecklat projektet tillsammans med handledaren Dr. Frostell, KTH och bihandledaren Dr. Shipin, AIT. Även Dr. Berg har haft en viktig roll i utvecklandet och det praktiska genomförandet av projektet. Oktober 2008 – december 2008 genomfördes fältstudier i Vientiane, Laos. Fakta till rapporten inhämtades främst från NGOs (Non- Governmental Organizations), institutioner, laboratorier, bibliotek, lokalbefolkning och internet. Detta skedde i form av tryckta papper/avhandlingar, elektroniska dokument, e-mail kontakter samt intervjuer. Under två dagar genomfördes fältstudier i TLM i samarbete med WWF. Syftet var att mäta vattenkvaliteten i våtmarken på ett antal förutbestämda platser. Gruppen bestod av en representant från WWF samt representanter från de tre distrikt som delar TLM. Strategic Environmental Assessment (Strategisk Miljöbedömning) Syftet med en SEA är att skapa hållbarhet i myndigheters beslutsprocesser. SEA integrerar både miljö och socioekonomiska aspekter i samma studie där målet är att sträva mot en hållbar utveckling. Olika SEA kan skilja sig i utformningen beroende på vilken handledning som används. Dock är dessa skillnader små och inträffar oftast i form av annorlunda terminologi och utförande. Normalt ingår moment som preliminär undersökning, genomförande av SEA, förberedelse av rapport, implementering av SEA i PPP (Policy, Plan och Program) samt utvärdering av implementeringen. Den här rapporten redovisar ytligt hur VIII en SEA genomförs enligt CIDA-modellen (Canadian International Development Agency) och enligt Europeiska Direktivet. Den senare handledningen används som standard i flertalet europeiska länder. Denna rapport kommer även att redovisa grunderna i EIA (Environmental Impact Assessment). Värdering av våtmarker Det finns ett antal olika sätt att värdera våtmarker. Ett sätt som redovisas i rapporten är att separera värderingsområdena till DUV (Direct Use Value), IUV (Indirect Use Value), OV (Option Value), och NUV (Non Use Value). Dessa summeras sedan till TEV (Total Economic Value). DUV beskriver de direkt synliga värdena av att bevara en våtmark, IUV de värden som är indirekta, OV de värden som kan vara möjliga i framtiden, NUV de värden som inte kan bedömas ur ett ekonomiskt och TEV våtmarkens sammanlagda värde. WATER Project Detta projekt är ett svar på de sanitära och ekologiska problemen som förekommer i Vientiane. Flertalet projekt har varit mindre framgångsrika vilket påverkat både samhället och ekosystemet negativt. För att råda bot på de sanitära problemen pågår för närvarande ett försök att informera myndigheterna om fördelarna med att bygga konstruerade våtmarker. Dessa skulle kunna vara ett alternativ till konventionella reningsverk. För att bevisa våtmarkernas effektivitet planeras nu byggandet av fem pilotanläggningar i Vientiane. Tre kommer användas för att rena kommunalt avloppsvatten medan två är avsedda för industriellt bruk. Projektet är en del av Wetland Alliance Programme. Samarbetspartners för WATER Project är laotiska staten, WWF Laos, WWF Tyskland och Wild Fowl & Wetland Trust (WWT), CORIN, AIT, WFC, CIDA och Sida. Indikationer tyder på att konstruerade våtmarker (22 hektar) kommer att byggas för rening av vattnet i dräneringskanalen Hong Ke. Detta är Vientianes mest förorenade kanal. Dock önskar WATER Project att totalt 61 hektar avsätts så att även kanalen Hong Xeng kan renas. New Town Development Project Projektet är ett samarbete mellan den laotiska och kinesiska staten. Planen är att ett omfattande utvecklingsprojekt ska locka flera utländska och inhemska investerare till Vientiane. Totalt kommer 1000 hektar lågt värderad mark att kommersialiseras. Ytterligare 200 hektar kommer att användas till byggandet av en konstgjord sjö som kompenserar för förlorad våtmarksyta. Kineserna har i gengäld lovat att bygga en sportarena för SEA Games 2009. 670 hektar kommer exploateras i TLM, 430 hektar i närheten av den nya sportarenan och 100 hektar i Dongphosy skogen. Kinesiska investerare kommer att arrendera marken under 50 år. Under denna period kan investerarna fritt göra affärer och har rätt att sälja marken till vem de vill. När 50 år har passerat har den laotiska staten rätt att ta tillbaka den arrenderade marken utan kompensation. Som modell för utvecklingsprojektet står kinesiska Suzhou City. Projektet beräknas kosta 800-1000 miljoner amerikanska dollar. Diskussion och slutsats Det spelar ingen större roll vilken metod som används för att nå en hållbar utveckling om den har någon form av internationell acceptans, är strategisk och tar hänsyn till att integrera både miljö och socioekonomiska frågor i samma studie. SEA och CEA (Cumulative Effect Assessment) är endast några alternativ. Målet med en SEA är först och främst inte avsedd för att skapa en rapport utan snarare hållbarhet i beslutsprocesser på PPP-nivå. Faktorer som motverkar hållbar utveckling i Laos är bland annat korruption, dålig utbildning och giriga investerare som maximerar sina ekonomiska vinster på miljön och samhällets bekostnad. Det är svårt att värdera OV eftersom denna parameter endast tar hänsyn till möjliga framtida värden. Samtidigt är NUV näst intill omöjligt att värdera eftersom denna parameter värderar kulturella och etiska värden. Värderingen av NUV blir då en subjektiv bedömning. Under New Town Development Project kommer flertalet människor i TLM tvingas flytta till en mer urban miljö. Dessa grupper är ofta speciellt sårbara eftersom de har bristfällig kunskap om urbana arbeten. Det är extra viktigt att myndigheterna följer upp dessa människor så att deras lidande minimeras. Förstörelsen av våtmarker beror troligtvis på i) stor tillförsel av vattenföroreningar (kommunalt och industriellt avloppsvatten), ii) fysisk destruktion (husbyggen, utfyllnad och konstgjorda dräneringssystem), iii) överutnyttjande av våtmarksresurser samt iv) invasioner och införanden av främmande arter som till exempel ”golden apple snail”. Teoretiskt skulle det vara möjligt att ersätta våtmarker med moderna tekniska lösningar för att undvika översvämningar. En lösning skulle vara att floden Houay Mak Hiao beläggs med ett cementlager för att öka vattenflödet ut från Vientiane. Dock har landet mycket svårt att finansiera denna typ av projekt och efterkommande underhåll på grund av små ekonomiska marginaler i statens budget. Det är heller inte helt kartlagt hur hydrologin i området fungerar. Ett annat problem med denna typ av lösning är att Houay Mak Hiaos vattenreningskapacitet och biodiversitet går förlorad. Om projektet genomförs måste vattenrening ske på annat sätt. Den här rapporten har försökt jämföra fördelarna med att använda konstruerade våtmarker (CW) istället för traditionella vattenreningstekniker. Att använda CW för att rena vattenmassorna i Hong Ke (avloppsvatten från gamla Vientiane) är nog det enklaste och billigaste alternativet medan den nya stadsdelen i mitten av TLM skulle kunna utrustas med ett konventionellt reningsverk. Detta eftersom de utländska stadsutvecklarna antagligen kommer ha tillräckligt med medel och kunskap för att stödja modern vattenreningsteknik som rymmer inom New Town Development Project. Infrastrukturen för att använda konventionella reningsverk är inte tillräckligt utvecklad i resterande Vientiane så att bygga ett konventionellt reningsverk i dessa delar av staden kan bli kostsamt. Dock blir situationen en annan i den nya stadsdelen eftersom denna byggs upp från grunden. Eftersom marken beräknas få ett avsevärt högre marknadsvärde kommer antagligen modern reningsteknik spara en del yta. Fördelar med konventionella reningstekniker är att dessa allmänt är mer avancerade, standardiserade, har en snabb omsättningstid på avloppsvattnet, är mindre platskrävande och processerna i dessa verk är bättre kartlagda. Däremot kan CWanläggningar användas under en längre tidsperiod, de har en hög effektivitet i varma klimat, har låg slamproduktion, kräver mycket små tillsatser av kemikalier, är enkla att underhålla, är mer estetiska, kräver enklare infrastruktur och har en låg driftskostnad. Författaren till denna rapport kan inte avgöra om det bästa för staden är att utvecklas till ett modernt urbant komplex. Dock är den nuvarande situationen ohållbar och därför bör någon form av åtgärder vidtas. Om organisationen och planering inom och mellan projekt förbättras minskar risken för misslyckade projekt. Det är viktigt att alla beslut som fattas grundas på ett korruptionsfritt hållbarhetstänkande. Om Vientiane strävar mot att ta ett större ansvar för miljö och socioekonomi så kommer landet som helhet att gynnas, eftersom huvudstaden är motorn i Laos ekonomi. Ett ökat okontrollerat utsläpp av vattenföroreningar från Vientiane kommer att öka belastningen på Mekongfloden. En biodiversitetskollaps i Mekongfloden skulle få allvarliga konsekvenser för landets fiske och ekonomi. De beslut som fattas idag kommer i framtiden att mer eller mindre påverka människor på ett lokalt, regionalt, nationellt och internationellt plan.

Large deformation shear and elongation rheology of polymers for electrospinning and other Industrial Processes

Ahirwal, Deepak 17 December 2013 (has links) (PDF)
The goals of this thesis are the characterization of polymer melts using mainly non-linear shear and extensional rheological techniques. The fabrication of scaffolds with excellent physical and mechanical properties using solution electrospinning technology for tissue engineering applications and the development of melt electrospinning equipment to facilitate the fabrication of solvent free scaffolds. To achieve the first goal, we focused on the characterization of entangled polymer melts in the linear and nonlinear viscoelastic regimes. The influence of molecular weight, Mw, molecular weight distribution (MWD), long-chain branching (LCB) and addition of particles to the polymer matrix on polymer melt properties were investigated using shear and extensional rheological techniques. The resulting structure-property relationships were established using newly introduced mechanical parameters under large amplitude oscillatory shear (LAOS) flow.

Du riz et des arbres – L'élimination de l'agriculture d'abattis-brûlis, une constante politique au Laos

Olivier, Ducourtieux 13 March 2006 (has links) (PDF)
L'agriculture d'abattis-brûlis est aujourd'hui pratiquée par 40 à 500 millions de paysans dans les régions tropicales. Depuis plus d'un siècle, un discours dominant condamne ce mode de production ; qualifié d'archaïque et peu productif, il serait une cause majeure de déforestation.<br />L'étude du système agraire de Phongsaly, petite région du Nord Laos, a permis d'appréhender la diversité et la rationalité des pratiques paysannes d'abattis-brûlis, qui se sont différenciées au cours de l'histoire récente du fait d'une intervention croissante de l'Etat. Les résultats locaux sont cohérents avec la revue de la bibliographie existante : la plupart des critiques de ce système de production s'avèrent infondées. Quand elles participent à la déforestation, ce qui n'est pas systématique, les agricultures d'abattis-brûlis en rotation n'y jouent qu'un rôle limité ; l'exploitation forestière et les agricultures pionnières en sont les principales causes. La complexité et la logique des systèmes agraires d'abattis-brûlis sont classiquement méconnues par les groupes sociaux tiers. Les pratiques des essarteurs, généralement des montagnards et de minorités ethniques, sont évaluées par des habitants des plaines en fonction de leurs préoccupations et des utilités qu'ils assignent à la forêt et la montagne. Les scientifiques n'apportent que rarement un éclairage rigoureux et objectif dans ces débats au sein desquels abondent trop souvent les lieux communs. L'agriculture paysanne contribuant souvent positivement à la gestion de l'environnement, il convient de la revaloriser. Les politiques agricoles devraient donc prendre en compte les savoirs et l'expérience des paysans pour la gestion durable des ressources naturelles. L'unique possibilité pertinente est l'association des paysans à l'élaboration et la mise en œuvre des interventions publiques.

Method The method I have used for collection of information is two-fold. The empirical data has mostly been derived via interviews with forestry officials and companies involved in forestry. The theoretical review and collection of secondary data has been performed by research of books, journals, reports, newspapers and online sources. The research methodology can accordingly be labelled "the actor approach" which methodology is based on understanding social entireties.

An important part of the method is my personal experience of Laos, from which I consider myself being able to base some conclusions. Theoretical Review Foreign market entry can generally be made in four modes: Exporting, licensing, joint ventures, or sole ventures. Foreign market entry strategies may involve adapting the marketing strategy. It may also necessitate product adaption.   Market entry in developing countries will most likely mean being exposed to unfamiliar environments. The general business conditions might be very different from the home market and constitute higher levels of trade barriers and sociocultural distance may be difficult to deal with. Case Study, Conclusions and Reflections The highlights from these two chapters include: <ul type="disc">Laos offers foreign investors to use any of the four market entry modes. Doing business in Laos receives a low international rating, especially in terms of labor restrictions. It also has rather high trade barriers. Laos is developing its commercial tree plantation sector and estimates suggest that the harvesting volumes will be increasing rapidly in the coming 10-15 years. Importing and selling forestry power equipment is restricted. Laos does not yet have any authorized dealer for chainsaws. This provides for interesting opportunities. The market is flooded with cheap, illegally imported, Chinese chainsaws, but it is questionable whether this actually constitutes any competition to Husqvarna, being a high quality brand. The Chinese chainsaws might however soon increase in terms of quality and be more competitive. Obtaining an import and sales license for outdoor power products may be a rather lengthy procedure but once in place would mean being the first authorized dealer - which might be advantageous.   Recommendation Due to Laos making efforts to increase the commercial tree plantation area, the harvesting volumes will increase rapidly the coming years. The sales potential for forestry equipment will hence increase in the years to come.   My recommendation to Husqvarna, if they have resources, is therefore to locate a dealer and enter the Laotian market. Plantations are however still mostly in the development phase. It is therefore doubtful that early entry is profitable enough to be motivated if there are other markets with higher potential that Husqvarna wants to enter.

A Study of the Structure and Dynamics of Smectic 8CB Under Mesoscale Confinement

Benson, James January 2012 (has links)
The structure and dynamics of the smectic-A liquid crystal 8CB (4 cyano-4 octylbiphenyl) when sheared and confined to mesoscale gaps (with crossed cylindrical geometry and mica confining surfaces) were studied using a Surface Forces Apparatus (SFA). Triangular shear patterns with frequencies of 0.01, 0.1, 1.0 and 10 Hz, and amplitudes of 62.5 nm, 625 nm and 6.25 m were applied to samples at gap sizes of 0.5 and 5.0 m. The study was performed at room temperature (20.5C) and at two higher temperatures (22C and 27C). In order to minimize the thermal fluctuations within the test chamber and hence to allow for the rapid re-initialization of test runs, the SFA was modified to allow for quick, precise and remote control of the confining surfaces. The procedure maximized the number of tests that could be undertaken with a single pair of surfaces so that a single gap geometry could be maintained for the duration of the test run. In order to run the SFA remotely, scripts written with a commercial software package, LabVIEW, were used to control of the SFA components, its FECO-monitoring camera and all its peripheral electronic equipment as well. Samples were agitated to disrupt any shear-induced liquid crystal domain alignment from previous testing following each shear test, and methodologies were developed to ascertain the extent of confinement quickly and remotely following agitation. Separate methods were developed for gap sizes at each extreme of the mesoscale regime, where the transition from bulklike structure and dynamics to nano-confinement occurs (between 1 and 10 microns for smectic-A 8CB). The results revealed that the greater amplitude-gap aspect ratio and surface-to-domain contact associated with smaller gaps facilitated reorientation of the domains in the shear direction. Evidence was also presented of domains at the higher end or outside of the mesoscale regime that, while straining and accreting, were unable to reorient and thereby led to an overall increase of viscoelastic response. The effective viscosity was found to obey a simple power law with respect to shear rate, , and the flow behaviour indices, n, slightly in excess of unity indicate shear thickening occurs with large enough shear amplitude, and that the viscosity reached a plateau near unity over shear rates of 0.005 to 500 s-1 within the mesoscale regime. Different K and n values were observed depending on the shear amplitude used. Unlike bulk smectic 8CB, whose domains do not align well in the shear direction with large shear-strain amplitude, at mesoscale levels of confinement large amplitude shearing (up to 12.5 shear strain amplitude) was found to be very effective at aligning domains. In general domain reorientation is found to be much more rapid within the mesoscale regime than has been reported in bulk. Aggressive shearing was found to result in a complete drop in viscoelastic response within seconds, while gentler shearing is found to produce a very gradual increase that persists for more than six hours, with individual shear periods exhibiting frequent and significant deviations from the expected smooth shear path that may be a product of discrete domain reorientations. From these findings, certain traits of the smectic 8CB domain structures under mesoscale confinement were deduced, including how they respond to shear depending on the level of confinement, and how their reorientation due to shear varies not only with shear rate but also independently with shear amplitude. An equation describing the viscosity change as a function of both shear rate and shear amplitude is proposed. The shear amplitude dependence introduces the notion of shearing beyond the proposed smectic 8CB “viscoelastic limit”, which was shown to exhibit behaviour in accordance with Large Amplitude Oscillatory Shear (LAOS) techniques developed for Fourier Transform rheology. The findings provided an understanding of the behavioural changes that occur as one reduces the level of confinement of smectic materials from bulk to nanoconfinement.

Traditional conflict resolution processes: mediation and rituals to address conflicts in multi-ethnic cultures of Laos

Stobbe, Stephanie Phetsamay 22 August 2011 (has links)
Countless millions of people in the world have little formally recognizable means for receiving any form of social justice. Laos, a small landlocked country in Southeast Asia, is a place that has seen some of the most brutal forms of poverty and violence. Over centuries, ethnic groups have been polarized and used by foreign powers to support their own agendas. In spite of this, the Lao people have consistently managed to recreate the peace and harmony that support their social relationships. Through the development and use of appropriate grassroots conflict resolution structures that do not require a formal court system, and exist outside the political arena, they have been able to resolve conflicts within and across cultural groups. Using in-depth interviews with different ethnic groups in Laos, this research examines traditional conflict resolution processes used in their communities. It identifies and discusses a Lao Conflict Resolution Spectrum, bringing particular attention to the Village Mediation Committee (Neoy Gai Geer). Laos' unique and most recognized conflict resolution ceremonies and rituals,the baci ceremony (soukhouan) and the reconciliation ceremony (soumma), are examined as tools for peacebuilding. These conflict resolution practices are significant in addressing conflict, repairing harm, rebuilding relationships, and restoring harmony to communities in conflict. The systems incorporate principles of effective conflict resolution, including transparency, accountability, inclusivity, flexibility, familiarity, accessibility, support networks, and relationship building. This research discovers how the conflict resolution systems of Laos are embedded in the fabric of grassroots life, and operate independently of the hierarchical structures that dominate governing institutions. It presents a case study of how people from a violent and impoverished past still manage to find ways to address their need for social justice and interconnectedness. The results provide greater understanding and appreciation of the contributions from diverse groups of people who are working daily to establish positive relationships, constructive and appropriate conflict resolution systems, and overall peace in their world. It demonstrates where peace can be found in difficult situations, among people who care little for political agenda and care a great deal about existing harmoniously with the people in their communities in order to mutually raise their quality of life.
