2. 1. Aspects of oral implant technology and osseointegration

   Author : Rainde Naiara Rezende de Jesus; Malmö universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

   Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.

4. 2. Adsorption of surface active elements on the iron (100) surface : A study based on ab initio calculations

   Author : Weimin Cao; Seshadri Seetharaman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sulfur; oxygen; surface adsorption; iron surface; ab initio calculations; adsorption energy; work function; difference charge density; thermodynamic stability; average velocity; Materials science; Teknisk materialvetenskap;

   Abstract : In the present work, the structural, electronic properties, thermodynamic stability and adatom surface movements of oxygen and sulfur adsorption on the Fe surface were studied based on the ab initio method. Firstly, the oxygen adsorbed on the iron (100) surface is investigated at the three adsorption sites top, bridge and hollow sites, respectively. READ MORE

5. 3. Algorithms and Interaction Potentials: phase density, surface tension and carbon dioxide

   Author : Rasmus Persson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; surface tension; carbon dioxide; density of states; bicalutamide;

   Abstract : This thesis is an amalgamation of articles (Papers I–V) by the author. We present a perturbation algorithm to calculate the phase density, and thus the partition function including its temperature dependence. READ MORE

6. 4. Solid Waste Landfills in an Arid Environment : Site Selection and Design

   Author : Ali Chabuk; Jan Laue; Nadhir Al-Ansari; Sven Knutsson; Hussain M. Hussain; Roland Pusch; Rafid Alkhaddar; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Landfill; Arid Environment; Site selection; Design; Babylon; Iraq; Soil Mechanics; Geoteknik;

   Abstract : Selecting landfill sites is considered a complicated task because its whole process is based upon several factors and restrictions. This study shows the present status of solid waste management, sources, collection personnel, machinery and equipment that are involved in the waste collection process, financing and financial management for the major cities of the Babylon Governorate in Iraq (Al-Hillah, Al-Qasim, Al-Mahawil, Al-Hashimiyah and Al-Musayiab).

7. 5. Theoretical and experimental studies of surface and interfacial phenomena involving steel surfaces

   Author : Weimin Cao; Seshadri Seetharaman; Oleg Ostrovski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sulfur; Oxygen; Adsorption; Iron surface; ab initio calculations; Adsorption energy; Work function; Difference charge density; Magnetic properties; Thermodynamic stability; Average velocity; Monte Carlo simulation; X-ray sessile drop method; Mass transfer; Interfacial velocity; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : The present work was initiated to investigate the surface- and interfacial phenomena for iron and slag/iron systems. The aim was to understand the mechanism of the effect of surface active elements on surface and interfacial properties. READ MORE
