  3. 2. Tillväxteffekter på lång sikt av gödsling i äldre tallbestånd : studie som undersöker huruvida gödsling påverkar tillväxten på lång sikt

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Hannes Alajärvi; Oskar Engström; [2022]
    Nyckelord :gödsling; tall; tillväxteffekter; tid; försök;

    Sammanfattning : The purpose of this study was to determine if fertilization had an impact on the long-term growth effects of pine forest on less fertile ground. It was done by using data from field trials to compare fertilized plots with control plots, and with that get results whether fertilization influences growth or not in a longer period, but also how production and height development acted together.

  4. 3. Design for prolonged service lifetime : A case study of built-in ovens implementing emotionally durable design in practice

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :JONATHAN BERG; HANNES ENGSTRÖM; [2021]
    Nyckelord :Emotionally durable design; Product longevity; Design framework; Sustainable design; Emotionellt hållbar design; Produktlivslängd; Designramverk; Hållbar design;

    Sammanfattning : The taxonomy of sustainable design covers a multitude of strategies targeting different aspects of product design, one of which is product longevity. Efforts within this field have mainly been focusing on extending the technical lifetime of products, whereas the issue of products being discarded before technical malfunction have received less attention.
