  1. 1. Towards co-management of Gialova Lagoon : A Natura 2000 coastal wetland in Messinia, Greece

    Författare :Georgios Maneas; Håkan Berg; Stefano Manzoni; Ernsteins Raimonds; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Salinity; wetland restoration; ecosystem services; participatory modelling; social-ecological system; naturgeografi; Physical Geography;

    Sammanfattning : The management of Natura 2000 sites is considered as the cornerstone for the conservation and restoration of biodiversity within Europe. However, protected ecosystems provide a plethora of benefits to local societies, and support the local economy. LÄS MER

  3. 2. Breating pattern by inductive plethysmography in relatidon to bronchial obstruction in asthma

    Författare :Tomas Strömberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : This work aimed at improving a method for "non-invasive" ventilatory monitoring (the respiratory inductive plethysmography; RIP), and at assessing whether RIP can be used for detection and monitoring of bronchial obstruction in asthma.The RIP measures the changes in rib cage and abdominal cross-sectional areas during breathing.

  4. 3. Constructive Commutative Algebra in Nonlinear Control Theory

    Författare :Krister Forsman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis consists of two parts. The first part is a short review of those results from commutative algebra, algebraic geometry and differential algebra that are needed in this work. The emphasis is on constructive methods. The second part contains applications of these methods to topics in control theory, mainly nonlinear systems. LÄS MER

  5. 4. The palaeolimnological record of regime shifts in lakes in response to climate change

    Författare :Linda Randsalu Wendrup; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; palaeolimnology; regime shifts; thresholds; alternative stable states; climate change; ecosystem dynamics; diatoms; hydrocarbons; monitoring; lake sediments; shallow lakes; 8.2 ka event;

    Sammanfattning : Regime shifts in lake ecosystems can occur in response to both abrupt and continuous climate change, and the imprints they leave in palaeolimnological records allow us to investigate and better understand patterns and processes governing ecological changes on geological time scales. This thesis aims at investigating palaeolimnological records of regime shifts in lakes during the Holocene to explore how lake ecosystems responded to climate changes and anthropogenic activities and to identify thresholds or tipping points that produced regime shifts.
