  1. 1. Lateral movements versus stationarity adaptive alternatives in benthic invertebrates to the seasonal environment in a boreal river

    University dissertation from Umeå : Umeå universitet

    Author : Tommy I. Olsson; Umeå universitet.; [1982]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Benthic invertebrates; cold-hardiness; ice; migrations; overwintering; river; seasonal variations; spatial distribution; spring flood; water level;

    Abstract : Benthic invertebrates inhabiting boreal rivers are exposed to very large seasonal variations in their physical environment. The extremes are in winter when the littoral area freezes solid and in spring when water flow increases rapidly. READ MORE

  3. 3. The effect of scale on the morphology, mechanics and transmissivity of single rock fractures

    University dissertation from Stockholm : Mark och vatten

    Author : Nader Fardin; KTH.; [2003]
    Keywords : Anisotropy; Aperture; Asperity degradation; Contact area; Finite Element Method FEM ; Flow analysis; Fractals; Fracture morphology; Heterogeneity; Stress-deformation; Surface roughness; Roughness-Length method; Scale dependency; Stationarity; Transm;

    Abstract : This thesis investigates the effect of scale on themorphology, mechanics and transmissivity of single rockfractures using both laboratory and in-situ experiments, aswell as numerical simulations. Using a laboratory 3D laserscanner, the surface topography of a large silicon-rubberfracture replica of size 1m x 1m, as well as the topography ofboth surfaces of several high-strength concrete fracturereplicas varying in size from 50mmx50mm to 200mm x 200mm, werescanned.

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ekonomiska system; ekonomisk politik; economic systems; economic theory; econometrics; Economics; Cross-Sectional Dependence; Output Convergence; Unit Root; Stationarity; Panel Data; Government Consumption; Non-Keynesian Effects; Private Consumption; economic policy; Nationalekonomi; ekonometri; ekonomisk teori; Fiscal Policy;

    Abstract : Popular Abstract in Swedish Den kanske viktigaste anledningen till att söka en grundläggande förståelse av ekonomiskt beteende är att erhålla ett underlag för utformningen och genomförandet av ekonomisk politik. Utan en sådan förståelse minskas möjligheterna att uppnå målen för den ekonomiska politiken. READ MORE
