  1. 1. Carbon dioxide dynamics in agricultural streams : Investigation of two streams draining catchments dominated by agricultural land

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Albin Bostner; [2020]
    Keywords : Carbon dioxide; dynamics; streams; agriculture; oversaturation; metabolic control; hyrdological control; Koldioxid; koldynamik; bäckar; jordbruk; övermättat; metabolisk kontroll; hydrologisk kontroll;

    Abstract : In recent years, streams draining agricultural land has been suggested to exhibit high carbon dioxide (CO2) concentrations when compared to streams draining other land-types. The transport of carbon from land to ocean is mainly occurring through the chain of inland waters, and with agricultural land today representing 40% of all continental area many of these inland waters are influenced by agricultural land.

  2. 2. Method development for rheological characterization of microfibrillated cellulose

    University essay from Karlstads universitet

    Author : Elin Wahlkrantz; [2020]
    Keywords : microfibrillated cellulose; MFC; rheology; characterization; dynamic rotational rheometer; complex viscosity; amplitude sweep; dry content; pH; conductivity; measuring geometry; gel; mikrofibrillerad cellulosa; MFC; reologi; karakterisering; dynamisk rotationsreometer; komplex viskositet; amplitudsvep; torrhalt; pH; konduktivitet; mätgeometri; gel;

    Abstract : This thesis contributes to a development of a method for rheological characterization of microfibrillated cellulose. The intended use of the method is to be able to distinguish between different grades of microfibrillated cellulose. READ MORE

  3. 3. Utvärdering av varierad mängd utsäde och gödning i maltkorn : är det lönsamt?

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Sofia Ramgren; [2020]
    Keywords : precisionsodling; maltkorn; varierad giva; försöksodling; Alnarps Egendom; lerhalt; markkartering; proteinhalt;

    Abstract : Teknikutvecklingen inom lantbruket går fort och det kan vara svårt att veta vilken teknik som man ska investera i. Framförallt är det svårt att veta om den är lönsam. Precisionsodling är en del i denna utveckling och används hos vissa lantbrukare. READ MORE

  4. 4. Data interpolation for groundwater modelling : How choice of interpolation method and sample size affect the modelling results

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Frida Agerberg; [2020]
    Keywords : Geohydrology; Groundwater; Modelling; Interpolation; SEEP W; Surfer; Geohydrologi; Grundvatten; Modellering; Interpolering; SEEP W; Surfer;

    Abstract : Over the past several decades, the use of groundwater modelling has been increasing in order to better evaluate the complexities inherent in hydrogeological calculations. Information required for groundwater modelling is for example elevation of soil and bedrock layers, which often is collected by drilling. READ MORE

  5. 5. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Eva Smedborn Pausson; [2019]
    Keywords : ;

    Abstract : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.
