   Sammanfattning : A mathematical model based on measurements in a whole-body counter described the retention of calcium in the human body. It was shown that the relative retention of intravenous and orally administered 47Ca in all subjects (n = 10 - 11) were well described by fitting a simple function of time with two free parameters to a few whole-body measurements after day 6, when the unabsorbed calcium had been excreted.

3. 2. Pharyngotonsillitis in primary health care. Aetiology and clinical findings

   Författare :Jon Pallon; Allmänmedicin och samhällsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharyngotonsillitis; Streptococcus pyogenes; Primary Health Care; Fusobacterium necrophorum;

   Sammanfattning : Pharyngotonsillitis, or acute sore throat, is a common reason for attending primary health care and a common reason for antibiotic prescription. Group A Streptococcus (GAS) has long been considered the most important pathogen in pharyngotonsillitis, but a wide array of other bacteria and viruses have also been associated with this condition.

4. 3. Supervisors' role in manual assembly

   Författare :Anna Grzelec; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assembly line; first-line management; motivation; supervisor;

   Sammanfattning : There are many different ways in which to analyze an organization when striving to achieve better performance. One such way is through analyzing the supervisors in the organization. The supervisor is the first management level, and is in charge of the production personnel, i.e. LÄS MER

5. 4. Superinductance and fluctuating two-level systems: Loss and noise in disordered and non-disordered superconducting quantum devices

   Författare :David Niepce; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Disordered Superconductors; Nanowire; Superinductor; Quantum information; Superconducting circuits; Superinductance; TLS; Two-level Systems;

   Sammanfattning : In this thesis, we first demonstrate that a disordered superconductor with high kinetic inductance can realise a microwave low-loss, non-dissipative circuit element with impedance greater than the quantum resistance. This element, known as a superinductor, can suppress the fluctuations of charge in a quantum circuit. LÄS MER

7. 5. Partial Oxidation of Methane over Functionalised Zeolites and Zeotypes

   Författare :Xueting Wang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; FTIR; Heterogeneous catalysis; Copper boron silicate; Zeolite; Natural gas; Biogas; Green methanol; zeotype; Temperature-programmed desorption; Cu-SSZ-13; Cu-ZSM-5; In situ infrared spectroscopy;

   Sammanfattning : Partial oxidation of methane to methanol is an industrially important process that allows natural gas and biogas to be utilised for methanol-based production of chemicals or converted to liquid methanol fuel, which make transportation more facile. In this thesis, the activity for partial oxidation of methane to methanol over copper functionalised zeolites and silica supported copper is investigated using a three-step quasi-catalytic approach including catalyst activation, methane reaction and methanol extraction by water.
