1. 1. Year-round production of forest seedlings under LED lamps : Biological and energetic implications of indoor cultivation

   Författare :Marco Hernandez Velasco; Uwe Zimmermann; Anders Mattsson; Frank Fiedler; Johanna Riikonen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Picea abies; Pinus sylvestris; year-round cultivation; forest seedlings; LED lamps; light quality; light quantity; daily light integral; adaptive lighting control; greenhouse integrated photovoltaics; agrivoltaics; seedling growth performance; short-day treatments; cold hardiness; light shock stress; Engineering Science; Teknisk fysik;

   Sammanfattning : Year-round cultivation of forest seedlings under light emitting diodes (LED) is a technology receiving increased attention from nurseries in the boreal forest regions. In these areas, the climate is characterized by strong seasonal fluctuations, resulting in short vegetation periods with narrow time windows for seedling transplanting and outdoor growth. LÄS MER

3. 2. There is no easy answer : Factors affecting meat quality in lambs

   Författare :Elin Stenberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : This thesis examined the effects of production system, slaughter method, carcass handling procedures and storage method on the quality of meat from intact male lambs. Quality aspects of the meat assessed were carcass quality, meat quality indicators (measured on carcasses), technological meat quality (measured on meat samples) and sensory attributes. LÄS MER

4. 3. Variation in raw milk quality : impact on milk coagulation and cheese ripening

   Författare :Hasitha Priyashantha; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : This thesis examined some of the causes behind recent increasing variation in ripening time of a traditional, Swedish long-ripening hard cheese. Variations in the composition and properties of farm and dairy silo milk intended for production of the long-ripening cheese were recorded during one year, and the resulting cheese was characterised.

5. 4. Forage feeding in intensive lamb production : intake and performance in ewes and lambs

   Författare :Carl Helander; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Successful feeding strategies of periparturient ewes and growing lambs are essential in intensive indoor lamb production. This thesis evaluated the effects of chopping grass silage and of mixing silage with concentrate on feed intake, dietary selection, chewing behaviour, faecal particle size and performance in pregnant and lactating ewes and in suckling and finishing lambs.

7. 5. Timber/Glass Adhesive Bonds for Structural Applications

   Författare :Louise Blyberg; Erik Serrano; Kent Persson; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Byggteknik; Civil engineering;

   Sammanfattning : Timber with its natural appearance and glass with its transparency may be appealing material for architects and users of modern buildings. Glass is a brittle material, but it is about six times stiffer than timber. Combined appropriately, the materials could form different types of composite products, e.g. LÄS MER
