    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Ida Westerberg; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Central America; Discharge; Flow-duration curve; Fuzzy regression; GLUE; Model evaluation; Non-stationarity; Observational uncertainty; Precipitation; Quality control; Rating curve; Regionalisation; Uncertainty estimation; Ungauged basins; Water resources; Avbördningskurva; Centralamerika; GLUE; icke-stationaritet; kvalitetskontroll; modellutvärdering; nederbörd; observationsosäkerheter; avrinningsområden utan vattenfö-ringsdata; oskarp regression; osäkerhetsuppskattning; regionalisering; varaktighetskurva; vattenföring; vattenresurser; NATURAL SCIENCES Earth sciences Atmosphere and hydrosphere sciences Hydrology; NATURVETENSKAP Geovetenskap Atmosfärs- och hydrosfärsvetenskap Hydrologi; Hydrology; Hydrologi;

    Sammanfattning : Knowledge about spatial and temporal variability of hydrological processes is central for sustainable water-resources management, and such knowledge is created from observational data. Hydrologic models are necessary for prediction for time periods and areas lacking data, but are affected by observational uncertainties. LÄS MER

  2. 2. Kinh Settlers in Viet Nam’s Northern Highlands Natural Resources Management in a Cultural Context

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Mats Lundberg; Linköpings universitet.; Linköpings universitet.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Viet Nam; northern mountains; highlands; wet rice agriculture; upland agriculture; shifting cultivation; natural resources use; local knowledge; culture; ethnicity; Naturresurser; Vietnam; etniska grupper; INTERDISCIPLINARY RESEARCH AREAS Water in nature and society; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Vatten i natur och samhälle;

    Sammanfattning : This study deals with the Kinh (or Viet) majority people who have migrated from the lowland Red River Delta to the mountainous areas of northern Viet Nam, and their adjustment to a new social and physical environment. Its aim is to analyse the social and cultural consequences for these migrants when settling in communities populated with people who belong to the national ethnic minorities (the Tày, the Giay and the Ngan peoples).

    Sammanfattning : Hydropower is the main source of electricity production in Iceland. In 2005, 80.8% of all electricity was generated by hydropower (7015 GWh). Hydropower production is affected both by variations and changes in discharge. LÄS MER

  4. 4. Approaching Curriculum Resources Examining the potential of textbooks and teacher guides to support mathematics learning and teaching

    Detta är en avhandling från Mälardalen University

    Författare :Linda Ahl; Mälardalens högskola.; Mälardalens högskola.; [2014]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Didactics; didaktik;

    Sammanfattning : The driving forces of conducting the two studies presented in this thesis are: the strong position of curriculum resources in the mathematics classroom in general; teachers’ faith in curriculum resources to convey the intentions and goals of mathematics education; and the expected benefits to mathematics education through expanding the knowledge base of research in the area of curriculum resources in general, and teacher guides in particular. This thesis builds upon two studies conducted in Sweden. LÄS MER

  5. 5. World oil supply and unconventional resources Bottom-up perspectives on tight oil production

    Detta är en avhandling från Uppsala : Department of Earth Sciences

    Författare :Henrik Wachtmeister; Uppsala universitet.; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oil supply; oil production; unconventional resources; tight oil; shale oil; bottom-up model; projections; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : Oil is the world’s largest primary energy source. It dominates the transportation sector which underpins the world economy. Yet, oil is a nonrenewable resource, destined not to last forever. In the mid-2000s global conventional oil production stagnated, leading to rising oil prices and fears of permanent oil scarcity.
