2. 1. Solution to boundary-contact problems of elasticity in mathematical models of the printing-plate contact system for flexographic printing

   Author : Nikolai Kotik; Yury Shestopalov; Stig Larsson; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; boundary-contact problem; elasticity; integral equation; approximate decomposition; Applied mathematics; Tillämpad matematik; Matematik; Mathematics;

   Abstract : Boundary-contact problems (BCPs) are studied within the frames ofclassical mathematical theory of elasticity and plasticityelaborated by Landau, Kupradze, Timoshenko, Goodier, Fichera andmany others on the basis of analysis of two- and three-dimensionalboundary value problems for linear partial differential equations.A great attention is traditionally paid both to theoreticalinvestigations using variational methods and boundary singularintegral equations (Muskhelishvili) and construction of solutionsin the form that admit efficient numerical evaluation (Kupradze).

4. 2. Bis(4-chlorophenyl) sulfone and PCB methyl sulfone metabolites : Trends and chirality in the Baltic Sea environment

   Author : Karin Norström; Åke Bergman; Mats Olsson; Roland Kallenborn; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; bis 4-chlorophenyl sulfone; PCB methyl sulfone; Baltic Sea; Environmental chemistry; Miljökemi;

   Abstract : The Baltic Sea was earlier identified as a highly polluted brackish water body and still is. The high concentrations of polychlorinated biphenyls (PCBs), p,p’-DDT and related compounds led to severe effects on several species in the Baltic region. READ MORE

5. 3. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

   Author : Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

   Abstract : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. READ MORE

6. 4. Block Copolymer Nanolithography for Sub-50 nm Structure Applications

   Author : Anette Löfstrand; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Sampolymer; riktad självorganisation; ytrekonstruktion; mönsteröverföring; sekventiell infiltrationssyntes; neutronreflektometri; Block copolymer; Directed self-assembly; Surface reconstruction; Pattern transfer; Sequential infiltration synthesis; Neutron reflectometry; Fysicumarkivet A:2021:Löfstrand;

   Abstract : As high technology device patterns are continuing to move towards decreasing critical dimensions and increasing pattern density, there is a need for lithography to move in the same direction. Block copolymer (BCP) lithography is a promising technique, which has single digit nanometer resolution, has a pattern periodicity of about 7-200 nm, and easily scales up to large area at a low cost.

7. 5. Ventilation Performance in Operating Rooms : A Numerical Assessment

   Author : Cong Wang; Sture Holmberg; Sasan Sadrizadeh; Anna Bogdan; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operating room ventilation; bacteria-carrying particles; laminar airflow; mixing ventilation; temperature-controlled airflow; computation fluid dynamics; Lagrangian particle tracking; Civil and Architectural Engineering; Byggvetenskap; Strömnings- och klimatteori; Fluid and Climate Theory;

   Abstract : Surgical site infections (SSIs) remain one of the most challenging postoperative complicationsof healthcare and threaten the lives of millions of patients each year. Current evidence hasshown a positive relationship between the airborne concentration of bacteria-carryingparticles (BCPs) in the operating room (OR) and the rate of infections. READ MORE
