1. 11. Development and optimization of a 3D in vitro model for osteogenic biomaterial evaluation

   Författare :Luis Oliveros Anerillas; Peyman Kelk; Paul J. Kingham; Mikko Lammi; Jöns Hilborn; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; angiogenesis; biomaterial; bone marrow mesenchymal stem cells; bone regeneration; hydrogel; osteoinduction; osteogenesis; scaffold; type I collagen; 3D culture; biology; biologi; biomedical laboratory science; biomedicinsk laboratorievetenskap; Medical Cell Biology; medicinsk cellbiologi;

   Sammanfattning : Despite the innate regenerative capabilities of bone tissue, self-repair is impaired when an injury exceeds the critical size threshold because of trauma, congenital, or pathological conditions. Autologous transplantation is the gold standard to reconstruct large bone defects. LÄS MER

3. 12. Bioaerosols and their importance for low-level Arctic clouds

   Författare :Gabriel Pereira Freitas; Paul Zieger; Radovan Krejci; Kevin J. Noone; Claudia Mohr; Martin Gallagher; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bioaerosols; Aerosols; Clouds; Arctic; Cloud Condensation Nuclei; Ice Nucleating Particles; Sea Spray Aerosol; Environmental Sciences; miljövetenskap;

   Sammanfattning : Bioaerosols are microorganisms or functional parts of them or other biological matter suspended in air. Examples are bacteria, viruses, pollen, spores, or smaller plant debris. In the atmosphere, bioaerosols can play various functional roles, such as facilitating the spread of genetic material. LÄS MER

4. 13. Chemical Tuning of the Magnetic Interactions in Layer Structures

   Författare :Sabina Ronneteg; Rolf Berger; J. Paul Attfield; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; neutron powder diffraction; magnetometry; layered magnetic structure; incommensurate helical structure; ThCr2Si2 type structure; antiferromagnetism; ferromagnetism; electronic structure calculations; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

   Sammanfattning : Thin metal films have found their use in many magnetic devices. They form pseudo two-dimensional systems, where the mechanisms for the magnetic interactions between the layers are not completely understood. LÄS MER

5. 14. Modeling Vibrational Electron Energy Loss Spectroscopy with the Frequency-Resolved Frozen Phonon Multislice Method

   Författare :Paul Michel Zeiger; Jan Rusz; Rebecca Nicholls; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electron Energy Loss Spectroscopy; Phonons; Scanning Transmission Electron Microscopy; Frozen Phonon Multislice; Molecular Dynamics; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Sammanfattning : Aberration correctors, improved monochromators, and better detectors have enabled exciting research with nanometer- and Ångstrom-scale resolution in the Scanning Transmission Electron Microscope (STEM). However the interaction of high-energy electrons with the many-body system of the sample is quite complex and hinders interpretation of experiments. LÄS MER

7. 15. Insights on weight maintenance and impacts of obesity for two rural populations in the United States and Sweden

   Författare :Melissa Brower Scribani; Margareta Norberg; Lars Weinehall; Paul Jenkins; Julie Sorensen; Kirsten Mehlig; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obesity; Obesity trends; Premature mortality; Obesity prevention; Weight maintenance; Primary weight maintenance; Rural; United States; Sweden; Public health; Public health; folkhälsa;

   Sammanfattning : Background: Obesity is a serious public health concern worldwide, and nearly 40% of all adults in the United States and 21% in Sweden are now living with obesity. Efforts focusing mainly on weight loss have fallen short in reducing obesity prevalence. LÄS MER
