  2. 16. Groundwater resources in hard rock coastal terrains : Insights into heterogeneity and spatial variability

    Author : Robert Earon; Bo Olofsson; Okke Batelaan; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Crystalline Rock; Groundwater Balance; Kinematic porosity; Groundwater Recharge; Water Security; Coastal Aquifer; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Challenges regarding water security in hard rock coastal regions with limited soil cover are: a seasonal absence of recharge during times of peak residency, heterogeneity and variability of the fracture network, close proximity to saline water sources and spatially inconsistent storage and extraction. In areas where it is not feasible to connect residents to municipal water systems, a better understanding of the resilience of reservoirs is needed. READ MORE

  4. 17. Process modelling based on data from an evaporation and a CTMP process : Analysis of energy efficiency and process variability

    Author : Daniel Ekbåge; Lars Nilsson; Helena Håkansson; Per Engstrand; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTMP; process modelling; evaporation; energy efficiency; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, paperboard, steam and other important components. Improved energy efficiency supports sustainability of the process and the products. READ MORE

  5. 18. Variability and feedbacks in the middle atmosphere

    Author : Maartje Kuilman; Bodil Karlsson; Qiong Zhang; Hauke Schmidt; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Middle atmosphere dynamics; noctilucent clouds; solar cycle effects; climate feedbacks; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : The importance of the middle atmosphere for the weather and climate on Earth is increasingly realized. Variability and feedback processes in the middle atmosphere need to be better understood and form the subject of this thesis. READ MORE

  6. 19. Measurement Variability Related to Insulin Secretion and Sensitivity : Assessment and Implications in Epidemiological Studies

    Author : Lars Berglund; Björn Zethelius; Johan Bring; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Geriatrics and medical gerontology; Geriatrik och medicinsk gerontologi; Geriatrics; Geriatrik;

    Abstract : There is a growing interest in random measurement variability of biological variables. In regression models, such variability of the predictors yields biased estimators of coefficients (regression dilution bias). READ MORE

  7. 20. The Location and Variability of Southern ocean Fronts

    Author : Robert M. Graham; Agatha M. de Boer; Jonas Nycander; Qiong Zhang; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. Moreover, the Subtropical Front (STF) is believed play a key role in the global climate system. READ MORE
