    Sammanfattning : Swedish dairy industry faced a cris i s of feed shortage in summer of 2018, followed by a dry autumn. The forage shortage was severe in some regions. During that period Swedish g overnment intervened by introducing a 1. LÄS MER

  3. 2. Prioritering av åtgärder för förbättrad juverhälsa i automatiska mjölkningssystem

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Elna Laxmar; [2019]
    Nyckelord :automatiska mjölkningssystem; somatiskt celltal; juverhälsa; förebyggande;

    Sammanfattning : Svensk mjölkproduktion har under de senaste 30 åren genomgått stora strukturförändringar. Allt fler gårdar väljer att ställa om från uppbundna system till lösdrifter med ökad mekanisering och automatisering. 40% av svenska mjölkkor kopplade till Växa Sveriges program kokontrollen mjölkas numera i automatiska mjölkningssystem (AMS).

  4. 3. N-body Simulations in Galactic Potentials

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :David Andersson; [2019]
    Nyckelord :N-body; simulation; spen clusters; dissolving time; Hyades; members of the Hyades; double integration; Physics and Astronomy;

    Sammanfattning : What effect does a collision between two clusters have on their dissolving time? In order to answer this question, a new type of N-body simulation using a double integration of a cluster was built. Instead of introducing a perturbation representing the gravitational force of the Milky Way into a local simulation of the cluster, the cluster orbit was integrated in the potential of the Milky Way, and in each of these integration steps the local motion of the stars inside the cluster were integrated, using an N-body calculation.

  5. 4. Multiradionuclide evidence for an extreme solar proton event around 2610 BP

    Master-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Martin Paschal Ohare; [2017]
    Nyckelord :cosmic-rays; cosmogenic radionuclides; NGRIP; GRIP; solar proton event; SPE; Earth and Environmental Sciences;

    Sammanfattning : Recently it has been confirmed that extreme solar proton events (SPE) can lead to significantly increased production of cosmogenic radionuclides (Mekhaldi et al. 2015). The evidence of these events can be recorded in tree rings (14C) and ice cores (10Be, 36Cl). LÄS MER

  7. 5. Anordning för rengöring avkomponent i mjölkningsrobot : Framtagning av lösning för förbättrad rengöring avspentvättkopp för att motverka bakterietillväxt

    Kandidat-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :Erik Lindbom; [2017]
    Nyckelord :rengöring; mjölkningsrobot; VMS; spen; tvätt; kopp; Erik; Lindbom; Delaval; mjölk;

    Sammanfattning : This report describes how to make the VMS teat cleaning cup clean itself properly.The purpose is to create a sulotion that make sure the whole cup gets washedduring normal cleaning. The solution should be compatible with earlier versionsof the VMS and will be tested to see if the amount of bacteria decreases. . LÄS MER
