    Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

  3. 17. Evaluation and implementation of quality control parameters for genome-wide DNA methylome sequencing

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Sara Ekberg; [2022]
    Keywords : ;

    Abstract : Epigenomics is the study of modifications to the genetic material without changes to the DNA sequence, one such modification is methylation of nucleotides. DNA methylation is associated with gene regulation and is studied in a variety of fields such as cancer and ageing. READ MORE

  4. 18. Omställning till hyggesfritt skogsbruk – föryngring i skog som ställts om från trakthyggesbruk till blädningsbruk

    University essay from SLU/School for Forest Management

    Keywords : plantetablering; omföring; markstörning;

    Abstract : Skogsstyrelsen har fått uppdraget att öka kunskapen och användandet av hyggesfria metoder i det svenska skogsbruket. För att hyggesfri skogsskötsel ska kunna bli vanligare behöver skog som tidigare skötts med trakthyggesbruk istället börja skötas med hyggesfria metoder. READ MORE

  5. 19. Investigation of non-metallic inclusions and chip properties in Cu-based alloys by numerical analysis

    University essay from KTH/Materialvetenskap

    Author : Ousmane El Hamid; Mattias Eriksson; [2022]
    Keywords : ;

    Abstract : Analysis of the macrostructure of metallic alloys is of utmost importance as there is a direct correlation on the physical properties and some features of the structures. This is true for copper based alloys and the non-metallic inclusions (NMI) that are enclosed in their structure. READ MORE
