   Abstract : Monolithic heterogeneous integration of III-V semiconductors with the contemporary Si Complementary Metal Oxide Semiconductor (CMOS) technology has instigated a wide range of possibilities and functionalities in the semiconductor industry, in the field of digital circuits, optical sensors, light emitters, and high-frequency communication devices. However, the integration of III-V semiconductors is not trivial due to the differences in lattice parameters, polarity, and thermal expansion coefficient. READ MORE

4. 2. On the Impact of Piston Motion and In-Cylinder Charge Composition on Energy Release, Auto Ignition and Emission Formation in Premixed Charge Internal Combustion Engines

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bränslen; sprängämnen; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; Internal Combustion Engine; Emission; SI; Spark Ignition; HCCI; Homogeneous Charge Compression Ignition; zone model; Chemical Kinetic; Engine simulation; Reformed Methanol; Hydrogen; Knock; Auto Ignition; NO; Piston Motion; Nitric Oxide; Premixed Charge;

   Abstract : The results presented in this thesis can be divided into four areas of investigation: Investigation of the effect of new volume-crank angle relations on engine emissions, power and efficiency; investigation of nitrogen oxides effect on auto ignition and knock in SI engines; investigation of premixed SI and HCCI engine operation with the alternative fuels hydrogen and reformed methanol gas (RMG); software development of a detailed chemical kinetics zonal engine model. Model development of the in-house two-zone chemical kinetic code focused on expansion of the Jacobian matrix to allow simulations of variable in-cylinder charge. READ MORE

5. 3. Healthcare financing challenges and opportunities to achieving universal health coverage in the low- and middle-income country context

   Author : Sayem Ahmed; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Background: In Bangladesh, on an average 62% of total healthcare spending was borne by households through out-of-pocket (OOP) payments annually during 2000- 2015. Because of such high OOP payments, a sizable proportion of households (15.7%) faced catastrophic health expenditure (CHE) and a number of them fell into poverty in 2010. READ MORE
