  1. 1. Causes and impact of surface water pollution in Addis Ababa, Ethiopia

    University essay from Uppsala universitet/Institutionen för geovetenskaper; Uppsala universitet/Institutionen för geovetenskaper

    Author : Malin Eriksson; Jonathan Sigvant; [2019]
    Keywords : Akaki river; E. coli; health risk; interview study; irrigation; physico-chemical parameters; water samples; Akaki; E. coli; fysikalisk-kemiska parametrar; hälsorisker; intervjustudie; vattenprover;

    Abstract : Surface water is globally becoming more and more a scarce resource, and in Addis Ababa the capital of Ethiopia, river water quality has been degraded due to anthropological forcing for many years. Therefore, the study objective was to investigate causes and impact of surface water pollution in Kebena and Great Akaki rivers. READ MORE

  2. 2. Occurrence and fate of organic micropollutants (OMPs) in Lake Mälaren

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Anna-Lena Rehrl; [2019]
    Keywords : multi-residue method; UPLC-MS MS; SPE; organic micropollutants; surface water;

    Abstract : The main objective of this study is to investigate the occurrence and fate of organic micropollutants (OMPs) in surface water in Lake Mälaren over one year, including their seasonal variations, correlations between compounds, spatial and vertical distribution. The water samples were enriched with solid phase extraction (SPE) and subsequently analyzed by ultra-high pressure liq-uid chromatography tandem mass spectrometry (UPLC-MS/MS). READ MORE

  3. 3. Physico-chemical evaluation of the water quality in Rocha River: A qualitative and comparative analysis including aspects of social and environmental factors

    University essay from Lunds universitet/Teknisk geologi

    Author : Stina Jacobson; Ida Sekizovic; [2019]
    Keywords : Cochabamba; Rocha River; water quality analysis; water pollution; wastewater; regulations; ICO-index; Hec-RAS; minor field study; Earth and Environmental Sciences; Technology and Engineering;

    Abstract : In this study, a physico-chemical analysis of the Rocha River was performed during the beginning of the rainy season 2018 in order to examine the current state of the water quality in the river at six different locations. The river, located in the Cochabamba department, Bolivia, was examined from upstream in Sacaba to downstream in Sipe Sipe. READ MORE

  4. 4. Physico-Chemical Properties, Probiotic Survival and Sensory Acceptability of a Liquid Oats-Based Beverage

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Evangelia Mitsou; [2017]
    Keywords : oat based drink; nordic berries; probiotic; synbiotic; Prevotella copri; nutritional analyses; carbohydrates; protein; fat; fibres; viscocity; beta glucans; β-glucans; shelf life; microbial analysis; sensory analysis; innovation; product development; food engineering; livsmedelsteknik; Technology and Engineering;

    Abstract : In the present thesis were studied oat based real fruit puree products. The aim was to create a new synbiotic beverage by combining the health benefits of the probiotic bacterial strain with the prebiotic ones derived from the β-glucans in oats. READ MORE

  5. 5. Flour from three local varieties of Cassava (Manihot Esculenta Crantz) - physico-chemical properties, bread making quality and sensory evaluation : a Minor Field Study in Ghana

    University essay from SLU/Dept. of Food Science

    Author : Estelle Eriksson; [2013]
    Keywords : cassava; flour; composite bread ; baking capacity; sensory evaluation;

    Abstract : Increasing costs for wheat imports due to higher demand for wheat-based food products in many tropical developing countries such as Ghana has led to an interest in cassava flour as partial substitute for wheat flour in bakery products. The aim of this study was to characterize physico-chemical properties of cassava flour compared to wheat flour and determine its maximum acceptable substitution level in composite wheat/cassava bread and cakes in terms of baking and organoleptical characteristics.
