   Sammanfattning : Agriculture has received renewed attention in poverty reduction efforts in Africa in recent years, and there are hopes that GM crops could have an important role in helping increase smallholder yields and reduce poverty. Drawing on critical discourse analysis (CDA) and livelihoods perspectives, this thesis examines the ideas governing the Massive Food Production Programme (MFPP), an agricultural development programme aiming to reduce poverty by raising agricultural production in Eastern Cape Province, South Africa, and its local effects when implemented in smallholder communities.

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conducting polymers; Living tissue engineering; In vivo polymerization; Plant Biohybrids; Hydra polyps; Energy storage; Glucose sensor;

   Sammanfattning : Life is the result of a multitude of electrical signals which drives our nervous system but also accomplishes a cascade of electrochemical reactions. In the 18th century, Lucia Galeazzi and Luigi Galvani got the idea to stimulate frog legs with electrodes. LÄS MER

5. 4. Vacuum Impregnation of Spinach Tissue: Metabolic Consequences and their Potential Industrial Applications

   Författare :Noor Liyana Yusof; Avdelningen för livsmedel och läkemedel; []
   Nyckelord :Vacuum impregnation; Metabolic consequences; Spinach : metabolism; Modified atmosphere; Minimal processing; Nitrate reduction; Vegetables; Plant tissue;

   Sammanfattning : Vacuum impregnation (VI) is a unit operation that allows the introduction of solutions into the porous structure of plant tissues. The plant tissue is immersed in the solution of interest and is then subjected to partial vacuum, causing the removal of air from the tissue. LÄS MER

7. 5. Application of Molecular Markers in Sugar Beet Breeding

   Författare :Annika Hjerdin Panagopoulos; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; breeding; marker application; molecular markers; sugar beet;

   Sammanfattning : Around 1750 a German chemist discovered it to be possible to extract sugar crystals from beet juice. Since then, breeding and improved agricultural practices have increased the concentration of sucrose per root from around 4% to around 18%. LÄS MER
