  1. 1. Glucose Sensing and Differentiating Systems with Organic Electrochemical Neurons : A Future Outlook for Type 2 Diabetes

    University essay from Linköpings universitet/Institutionen för teknik och naturvetenskap

    Author : Sophie Ziske; [2024]
    Keywords : organic electronics; organic electrochemical neuron; organic electrochemical transistor; type 2 diabetes; closed-loop system; Axon-Hillock neuron; astable multivibrator; vagus nerve stimulation; glucose sensing and differentiation; applied physics; biomedical engineering; electronics;

    Abstract : In recent years great advances in the field of biomedical engineering and organic electronics have been achieved. One promising application would be the regulation of blood glucose concentration in type 2 diabetes patients. This application would eliminate medication and would improve the standard of life.

  3. 2. Circular economy: : Sustainability assessment of circular business models basedon material flow analysis.

    University essay from Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Author : Sara Ankar; [2023]
    Keywords : Circular economy; Circular business models; Product-Service-System; Profitability; Climate impact; Material Flow Analysis;

    Abstract : This study has contributed to the developing concepts of circular economy by assessing circular business models and to test different approaches for circularity in a measurable way. In our current era of time, we stand against environment challenges with a warming planet and resources scarcity. READ MORE

  4. 3. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  5. 4. Studies on future Mine Countermeasure Vessels (MCMV)

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Philip Somehagen; [2023]
    Keywords : Concept development; Mine countermeasure vessels; ROV; Sonar; Konceptutveckling; Minjaktsfartyg; ROV; Sonar;

    Abstract : Background Maritime transportation is vital for international trade, and any disruption to this flow can have severe financial and environmental consequences. Ship mines, both old and new, present significant risks as man-made obstacles. READ MORE

  6. 5. Qualitative Analysis of Chlorinated Paraffins in Recycled Plastics

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Solal GAUDIN; [2023]
    Keywords : Short chain Chlorinated Paraffins SCCP Medium chain Chlorinated Paraffins MCCP Long chain Chlorinated Paraffins LCCP Recycled plastics Qualitative analysis Bioaccumulation Long range transport Gas Chromatography – Mass spectrometry;

    Abstract : Described in many studies as dangerous for the environment and potentially carcinogenic for humans, Chlorinated Paraffins (CPs) are easily widespread due to their substantial production and use in different products. Previous studies reported the presence of CPs in different plastic polymers. READ MORE
