  1. 1. Optimizing purification of oligonucleotides with reversed phase trityl-on solid phase extraction

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Ninorta Bartuma; [2019]
    Keywords : Oligonucleotides; purification; trityl-on; SPE; AIE-HPLC;

    Abstract : Oligonucleotides are synthetic strings of DNA or RNA used mostly for biochemical analysis and diagnostics. For them to be useful in these fields, a purity over 90% is most often required. However, when synthesizing these sequences, many “failures” (shorter sequences) are made in the step-wise process.

  3. 2. Novel Ammonia Storage Materials for SCR Systems : Carbon Materials – Salt Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nicolas Grimaldos Osorio; [2019]
    Keywords : magnesium chloride; ammonia; carbon materials; SCR; NOx reduction; sorption;

    Abstract : The emissions of nitrogen oxides (NOx) are a serious environmental problem due to its relationship with the formation of smog, acid rain and because they are dangerous for human and animal health. These gases are produced in high quantities in diesel engines used for automotive applications, and different strategies are being used to reduce them, among which are the Selective Catalytic Reduction (SCR) systems.

  4. 3. Investigation of soil related potential for sustainable growth and development of Oil Palm (Elaeis quineensis Jacq) in Nigeria

    University essay from SLU/Dept. of Soil and Environment

    Author : Wisdom Ofremu; [2013]
    Keywords : Nigeria; oil palm; oil palm management; palm oil; soil properties; soil fertility; Nigerian Institute for Oil Palm and Research NIFOR ;

    Abstract : Seven representative soil sites at the Nigerian Institute for Oil Palm and Research (NIFOR) were studied to evaluate the present fertility status of the soils for sustainable production of palm oil and in particular investigate the soil boron status. Profiles were sited at Edo State (Ed1, Ed2 and Ed3) and Akwa Ibom State (Akwa1, Akwa2, Akwa3 and Akwa4). READ MORE

  5. 4. Chlorination of organic material in different soil types

    University essay from Tema vatten i natur och samhälle; Filosofiska fakulteten

    Author : Malin Gustavsson; [2009]
    Keywords : Chlorination; organic chlorine; forest soil; retention; biogeochemical cycle; klorering; organiskt klor; skogsjord; biogeokemisk cykel;

    Abstract : Research has shown that formation of chlorinated organic matter occurs naturally and that organic chlorine is as abundant as the chloride ion in organic soils. A large number of organisms are known to convert inorganic chloride (Clin) to organic chlorine (Clorg) (e.g. READ MORE

  6. 5. Modeling Chloride Retention in Boreal Forest Soils - synergy of input treatments and microbial biomass

    University essay from Tema vatten i natur och samhälle

    Author : Stephen Kayode Oni; [2007]
    Keywords : Biogeochemical model; Chlorine biogeochemistry; Chlorine cycles; Chloride immobilization; Microbial Biomass; Water residence time;

    Abstract : The hypothetical assumption that chloride is conservative in the soil has been debated for the last decade. The results of the recent years of study in chlorine biogeochemistry show that chloride is non-conservative but rather participates in complex biogeochemical reactions in the soil. READ MORE
