  1. 16. Genetic variation in natural populations: a modeller's perspective

    Författare :Marina Rafajlovic; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; coalescent process; site frequency spectrum; multiple paternity; dominant clone; divergent selection;

    Sammanfattning : Thanks to advances in genome sequencing, empirical patterns of within- and between-species genetic variation are readily available. By studying these patterns much has been learned about the evolutionary histories of species. But the causes and consequences of different evolutionary histories are still difficult to tell apart.

  3. 17. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight

    Författare :Sojeong Ka; Finn Hallböök; Tom Porter; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chicken; juvenile body weight; divergent selection; gene expression; DNA microarray; quantitiative RT-PCR; hypothalamus; neural plasticity; melanocortin system; endogenous retrovirus; carnitine palmitoyltransferase-1b; Neurobiology; Neurobiologi; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Sammanfattning : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. LÄS MER

  7. 20. Coordinated control of Multi-Stage Inventory System

    Författare :Johan Marklund; Produktionsekonomi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inventory systems; multi-echelon; stochastic; decentralization; centralized control; distribution system; divergent system; echelon-stock; installation-stock.;

    Sammanfattning : This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. LÄS MER
