1. 1. Insights into potato plant immunity reveals Parakletos as a novel ROS suppressor

   Författare :Muhammad Awais Zahid; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Potato (Solanum tuberosum L.) is the world's third most commonly grown food crop with very high yield potential. However, its production is hampered by several pathogens, with consequent yield losses. Existing control methods include frequent, costly fungicide applications, and classical breeding is complicated in potato. LÄS MER

3. 2. An Experimental Study to Improve the Casting Performance of Steel Grades Sensitive for Clogging

   Författare :Jennie Svensson; Pär Jönsson; Voicu Brabie; Lauri Holappa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Preheating; Decarburization; RBM; Clogging; SEN; Plasma sprayed coating; CaTiO3; YSZ; Continuous casting; Pilot plant trials; Industrial plant trials; Clean steel; Tundish; Non-metallic inclusions; MISS; Materials Science and Engineering; Teknisk materialvetenskap; Steel Forming and Surface Engineering;

   Sammanfattning : In this study, the goal is to optimize the process and to reduce the clogging tendency during the continuous casting process. The focus is on clogging when the refractory base material (RBM) in the SEN is in contact with the liquid steel. LÄS MER

4. 3. Quantitative Genetics and Genomic Selection of Scots pine

   Författare :Ainhoa Calleja-Rodriguez; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The final objective of tree improvement programs is to increase the frequency of favourable alleles in a population, for the traits of interest within the breeding programs. To achieve this, it is crucial to decompose the phenotypic variance accurately into its genetic and environmental components in order to obtain a precise estimation of genetic parameters and to increase genetic gains.

5. 4. Modification of forest trees by genetic engineering : from design to the field

   Författare :Evgeniy Donev; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Developing viable genetic engineering methods for cell wall modification in trees is important to improve in a timely manner the properties of lignocellulose for biorefinery applications. New wood cell wall functionalities can be introduced by altered expression of native enzymes or by expressing microbial enzymes in planta. LÄS MER

7. 5. Fluid Flow Phenomena, Inclusion Characteristics and some Heat Transfer Phenomena during Filling of an Ingot Mmold

   Författare :Robert Eriksson; KTH; []
   Nyckelord :up-hitt teeming; model powder; inclusions; plant trials; thermal diffusivity; fluid flow; physical modeling;

   Sammanfattning : Clean steel production requires a good understanding of theinclusion characteristics at all stages of the steelmakingprocess. So far there exist little information about theformation and evolution of inclusions during the filling ofingot molds. LÄS MER
