   Sammanfattning : Cancer represents a significant global public health challenge and ranks as the second mostcommon cause of death in the United States. The onset of cancer entails an initial phasewhere cells lose their polarity and disconnect from the normal basement membrane, allowingthem to form distinct three-dimensional (3D) configurations that interact with adjacent cellsand the surrounding microenvironment.

3. 17. Graphene-based nanocomposites for electronics and photocatalysis

   Författare :Ebrahim Chalangar; Håkan Pettersson; Magnus Willander; Omer Nour; Maria Messing; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Zinc oxide; Silver iodine; Plasmonics; Nanocomposites; Conjugated electronics; Photocatalysis; Photodegradation;

   Sammanfattning : The development of future electronics depends on the availability of suitable functional materials. Printed electronics, for example, relies on access to highly conductive, inexpensive and printable materials, while strong light absorption and low carrier recombination rates are demanded in photocatalysis industry.

4. 18. Rättsligt skydd av biologisk mångfald : etiska perspektiv och normkonflikter

   Författare :Caroline Gardelli; Maria Pettersson; Lars Bäckström; Henrik Josefsson; Luleå tekniska universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; miljörätt; miljöetik; biologisk mångfald; invasiva främmande arter; försiktighetsprincipen; normkonflikt; Law; Rättsvetenskap;

   Sammanfattning : En förutsättning för att vi ska uppnå en hållbar utveckling är att vi bevarar den biologiska mångfalden, vilken bland annat hotas av införsel och spridning av invasiva främmande arter. Ett viktigt instrument för att skydda den biologiska mångfalden utgörs av de rättsliga ramar som satts upp på internationell, EU- och nationell nivå. LÄS MER

5. 19. Fluid Power Pumps and the Electrification : With a Focus on Discrete Displacement Control in Load Handling Applications

   Författare :Samuel Kärnell; Liselott Ericson; Petter Krus; Maria Pettersson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : More and more vehicles are being electrified. Mobile working machines and heavy trucks are not excluded, and these machines are often hydraulically intense. Electrification entails new requirements for the hydraulic system and its components, and these requirements must be taken into consideration. LÄS MER

7. 20. Biodiversity Protection in an Aspiring Carbon-Neutral Society : A Legal Study on the Relationship between Renewable Energy and Biodiversity in a European Union Context

   Författare :Melina Malafry; Gabriel Michanek; Maria Pettersson; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmental law; nature protection; renewable energy; biodiversity protection; environmental impact assessment; Miljörätt; Environmental Law;

   Sammanfattning : There is a vision in the EU for a transition to a low carbon society, including a carbon-neutral energy system, containing a high share of renewable energy. However, this vision is not isolated from other political goals, such as halting the loss of biodiversity by 2020. LÄS MER
