1. 6. Erysipelothrix rhusiopathiae in laying hens

   Författare :Helena Eriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The bacterium Erysipelothrix rhusiopathiae can infect a wide range of mammals (including humans) and birds. Disease outbreaks (erysipelas) have been considered unusual in chickens internationally, but outbreaks with high mortality and egg production losses have been diagnosed in Swedish laying hen flocks every year since 1998.

3. 7. Leaf Area Index of Scandinavian Forests Methods Using in situ and Remotely Sensed Data

   Författare :Helena Eriksson; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geologi; fysisk geografi; Physical geography; geomorphology; Geology; physical geography; leaf aggregation; specific leaf area SLA .; Växtekologi; Plant ecology; Leaf area index LAI ; canopy reflectance models; spectral vegetation indices; remote sensing; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

   Sammanfattning : This thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. LÄS MER

4. 8. Work-related cardiovascular disease

   Författare :Helena Eriksson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational noise; shift work; job strain; seafarer; cardiovascular disease;

   Sammanfattning : The overall aim of this thesis was to study occupational risk factors for cardiovascular disease, particularly, occupational noise, job strain and shift work. Incidence of cardiovascular disease was analysed in a general population sample, the Primary Prevention Study, in relation to exposure to noise and job strain. LÄS MER

5. 9. A Salutogenic perspective on resistance training : a study on healthy old adult women

   Författare :Helena Ericson; Mikael Quennerstedt; Monica Eriksson; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health resources; exercise; resistance traning; salutogenes; old adult women; healthy aging; hope; negative affect; psychological outcomes; Sports Science; Idrottsvetenskap;

   Sammanfattning : The number of people aged 60 years and over has doubled since 1980and the World Health Organization predicts that the population of over60s will reach 2 billion by the year 2050. An ageing population poses bothchallenges and opportunities for society and for individuals. LÄS MER

7. 10. Drug absorption in the lungs : studies in the isolated perfused rat lung model combined with physiologically based biopharmaceutics modelling

   Författare :Johanna Eriksson; Hans Lennernäs; Erik Sjögren; Helena Thörn; Ben Forbes; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pulmonary drug absorption; physiologically based biopharmaceutics modeling; pulmonary drug delivery; Biofarmaci; Biopharmaceutics;

   Sammanfattning : Pulmonary delivery of drugs is the preferred route of administration for treatment of local lung diseases like asthma and chronic obstructive pulmonary disease. Recently, there has also been increased interest in systemic delivery of drugs via the lungs to avoid problems with low and/or variable gastrointestinal absorption, and as a needle-free alternative for drugs that cannot be ingested.
