  1. 1. Stratigraphy and palaeoenvironment of the early Jurassic volcaniclastic strata at Djupadalsmölla, central Skåne, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Per Wahlquist; [2023]
    Keywords : volcaniclastic; Djupadalsmölla; CSVP; palynomorphs; early Jurassic; late Pliensbachian; Earth and Environmental Sciences;

    Abstract : From the almost 200 volcanic outcrops in the Central Skåne Volcanic Province (CSVP), only three are of volcaniclastic material. These volcanoclastics, and the transition to the underlying crystalline basement, have been investigated for the first time in a drill core (KBH2) from Djupadalsmölla in order to understand the stra-tigraphy, depositional process, age of deposition, and depositional environment.

  3. 2. Method evaluation for probing DNA sorption to clay minerals : Evaluation of fluorescent and spectroscopic quantification of DNA as well as DNA interactions of Kaolinite and Montmorillonite

    University essay from Umeå universitet/Kemiska institutionen

    Author : Oskar Wangdell; [2022]
    Keywords : ;

    Abstract : The association of DNA/RNA to mineral surfaces is an emerging field with widespread applications from biotechnological solutions to paleogenetics. Evaluating available methods to quantify adsorption will be essential to further investigate how to control and predict loading of DNA onto minerals. READ MORE

  4. 3. Evolution and Differentiation of Large Icy Moons

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Piia Tomberg; [2021]
    Keywords : Physics and Astronomy;

    Abstract : Purpose: In preparation of several future missions with the objective to research the large icy moons of the Solar System, it is necessary to have a cohesive understanding of the conditions that might lead to the formation of liquid oceans in these moons. The purpose of this work is to create a numerical model for simulating the temperature evolution of the cores of large icy moons. READ MORE

  5. 4. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Hani Yahya Ali Shubail; [2020]
    Keywords : Constructed wetland; Decentralized wastewater treatment; Jordan; On-site wastewater treatment system;

    Abstract : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. READ MORE

  6. 5. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

    University essay from Lunds universitet/Kemiska institutionen

    Author : Mona Koder Hamid; [2020]
    Keywords : clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

    Abstract : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].
