  1. 1. Thermochemical energy utilization of biomass in Rwanda - a screening of potential feedstocks

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Felix Johansson Carne; [2022]
    Keywords : bioenergy; agricultural; residues; waste; agroforestry; africa; energiteknik; bioenergi; jordbruksrester; afrika; termokemisk; bränslen;

    Abstract : Traditional bioenergy practices in sub-Saharan Africa involve collecting natural forest wood and burning it in simple fireplaces for household cooking. This is actually still very common, especially in rural areas. The situation is unfortunately connected to health issues, inequality and natural forest degradation and deforestation. READ MORE

  3. 2. A 3D-printed Fat-IBC-enabled prosthetic arm : Communication protocol and data representation

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Johan Engstrand; [2020]
    Keywords : prosthetic arm; bionic arm; 3D-printing; intra-body communication; ibc; fat tissue; fat-ibc; arduino; xbee; 802.15.4; cobs; cobs r; packet loss; serial transmission; armprotes; 3D-utskrift; intrakroppslig kommunikation; fettvävnad; paketförlust; seriell överföring;

    Abstract : The aim of this thesis is to optimize the design of the Fat-IBC-based communication of a novel neuroprosthetic system in which a brain-machine interface is used to control a prosthetic arm. Fat-based intra-body communication (Fat-IBC) uses the fat tissue inside the body of the bearer as a transmission medium for low-power microwaves. READ MORE

  4. 3. Effects of different biochar application rates on soil fertility and soil water retention in on-farm experiments on smallholder farms in Kenya

    University essay from SLU/Dept. of Soil and Environment

    Author : Helene Puehringer; [2016]
    Keywords : biochar; soil water retention; bulk density; macro nutrient availability; VNIR; maize cobs and stover; coffee husk;

    Abstract : Biochar is produced through pyrolysis, the thermo-chemical degradation of biomass under anaerobic or oxygen-limited conditions. Due to its properties related to surface area and porosity, bulk density, nutrient content, stability, cation exchange capacity (CEC), pH value, and carbon content, biochar has the potential to improve physical as well as chemical soil properties and thus improve crop productivity and contribute to carbon sequestration.
