1. 1. Cutting Edge Titanium-based CVD Hard Coatings

   Författare :Linus von Fieandt; Mats Boman; Ulf Jansson; Erik Lindahl; Tommy Larsson; Henrik Pedersen; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CVD; Hard coatings; Ti C; N ; TiN;

   Sammanfattning : Modern tools for metal cutting applications, such as turning or milling, are typically improved with a thin protective coating. Despite being only a few microns thick, the coating can increase the lifetime of the tool by more than 100 times compared to an uncoated tool. Two different types of techniques are normally used to deposit the coatings, i. LÄS MER

3. 2. Female Licentiousness versus Male Escape? : Essays on Intoxicating Substance Use, Sexuality and Gender

   Författare :Alexandra Bogren; Karin Helmersson Bergmark; Willy Pedersen; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; alcohol; drugs; intoxication; nature - culture; sexuality; gender; young people; Sweden; Sociology; Sociologi;

   Sammanfattning : The purpose of this thesis is to study cultural aspects of alcohol and drug use in Sweden, and also to some extent in other countries. In the context of changing patterns of drinking and drug use in Sweden and in the rest of the world, such studies are increasingly important.The thesis comprises four self-contained but interrelated studies.

4. 3. Human response to wind turbine noise : perception, annoyance and moderating factors

   Författare :Eja Pedersen; Sten Ljunggren; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Noise; Environmental exposure; Wind; Audio-visual interaction; Low-level noise exposure; NATURAL SCIENCES; NATURVETENSKAP; wind turbines; noise annoyance; sound perception; audio-visual interaction; low-level noise exposure;

   Sammanfattning : Aims: The aims of this thesis were to describe and gain an understanding of how people who live in the vicinity of wind turbines are affected by wind turbine noise, and how individual, situational and visual factors, as well as sound properties, moderate the response.Methods: A cross-sectional study was carried out in a flat, mainly rural area in Sweden, with the objective to estimate the prevalence of noise annoyance and to examine the dose-response relationship between A-weighted sound pressure levels (SPLs) and perception of and annoyance with wind turbine noise.

5. 4. Method for measurement of exposure to electrophiles : Strategy for identification and exposure estimation using N-terminal haemoglobin adducts

   Författare :Efstathios Vryonidis; Margareta Törnqvist; Hitesh Motwani; Isabella Karlsson; Marie Pedersen; Gabriele Sabbioni; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haemoglobin adducts; Electrophilic exposure; LC-MS; Adductomics; Acrylamide; Environmental Sciences; miljövetenskap;

   Sammanfattning : We are exposed to many chemicals in our everyday life. Some of these chemicals could pose risks for our health. To reduce such risks, it is important to know what we are exposed to, how much, and how toxic the chemicals are. LÄS MER

7. 5. Chemical vapour deposition of sp2-hybridised B-C-N materials from organoborons

   Författare :Laurent Souqui; Anne Henry; Hans Högberg; Henrik Pedersen; John R. Abelson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; boron nitride; epitaxy; CVD; boron carbide; carbonitride; PECVD;

   Sammanfattning : Thin films of sp2-BN are promising materials for graphene and deep-UV optoelectronics. They are typically deposited by thermally activated chemical vapour deposition (CVD) from triethylboron (TEB) and ammonia (NH3) at 1500 °C, albeit in a narrow process window. LÄS MER
