2. 1. Psychosocial Stress, Mental Health and Salivary Cortisol in Children and Adolescents

   Author : Per E Gustafsson; Per A Gustafsson; Nina Nelson; Ingemar Engström; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Stressful experiences and conditions in childhood influence the health and well-being of the growing individual, and can also confer a long-lasting impact into adult life. Delineating the social, mental and biological aspects of stress in children and adolescents is therefore of great concern for human beings. READ MORE

4. 2. Identifying Patterns of Emotional and Behavioural Problems in Preschool children : Facilitating Early Detection

   Author : Berit M. Gustafsson; Per A Gustafsson; Mats Granlund; Marie Proczkowska; Eva Billstedt; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Mental health problems often debut in early childhood and may last throughout adulthood, thereby making early detection and intervention especially important. The overarching aim of the present thesis was to identify patterns of emotional and behavioural problems indicating mental health problems in preschool children. READ MORE

5. 3. Oesophageal function, acid reflux and bronchopulmonary disease : A study on children and adolescents with asthma or cystic fibrosis

   Author : Per Gustafsson; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : This thesis comprises a literature review of gastro-ocsophageal reflux (GOR) and six studies which aim to determine the prevalence of oesophageal dysfunction (OD) and pathological GOR and their significance concerning the bronchopulmonary disease in children and adolescents with bronchial asthma or cystic fibrosis (CF). Oesophageal function was assessed by manomctry combined with oesophageal provocation tests. READ MORE

6. 4. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses

   Author : Per-Johan Gustafsson; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cracking; corners; test-specimens; strength; tension; fracture mechanics; strain localization; size-effect; flexural strength; LEFM; fictitious crack model; Weibull; FEM; pipes; shear strength; concrete; diagonal tension;

   Abstract : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. READ MORE

7. 5. Design and application of experimental methods for steel sheet shearing

   Author : Emil Gustafsson; Mats Oldenburg; Per Gradin; Lars Karlsson; Luleå tekniska universitet; []
