  1. 1. Recovery of biochemicals from ABE fermentation broths using MFI adsorbents: A comparison between traditional beads and a structured adsorbent

    Författare :Abrar Faisal; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Sammanfattning : Energy demands of the world are ever increasing in this industrial era. Over reliance on petroleum-based fuels has a negative impact on the environment. In addition, with depleting reservoirs of fossil fuels, the need for new, sustainable fuels and chemicals is more urgent than ever. LÄS MER

  2. 2. Just Waiting : Ethical Challenges in Priority Setting Posed by Organ Scarcity in Kidney Transplantation

    Författare :Faisal Omar; Stellan Welin; Per Carlsson; Jan Erik Paulsen; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : Over the last few decades kidney transplantation has transformed from an experimental treatment to the treatment of choice for end-stage renal disease. Unfortunately, however, the established organ donation models in many countries, relying chiefly on altruism, fail to motivate a sufficient number of donors. LÄS MER

  3. 3. Socioeconomic patterns of overweight and obesity in Scania, Sweden

    Författare :Faisal Al-Emrani; Socialmedicin och global hälsa; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Overweight; obesity; socioeconomic inequality; social gradient; SES; BMI; social capital; birth cohort; ageing; retirement; Scania Public Health Cohort; Sweden;

    Sammanfattning : Overweight and obesity are major social and public health concerns globally. The obesity epidemic is caused by a widespread chronic energy imbalance between high-energy intake and low-energy expenditure, but this mechanism appears to be modified by a number of other biological, behavioral, and social factors that interact in a complicated manner.

  4. 4. On Modeling and Optimal Control of Modular Batteries: Thermal and State-of-Charge Balancing

    Författare :Faisal Altaf; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex optimization; converters; electrified vehicles.; model predictive control; thermal balancing; SOC balancing; battery control; Modular batteries;

    Sammanfattning : There has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs) to reduce carbon footprint of transportation and the dependence on fossil fuels. Since the battery pack of xEVs is one of the most expensive but a key component in the powertrain, the battery lifetime is an important factor for the success of xEVs. LÄS MER

  5. 5. Thermal and State-of-Charge Balancing of Batteries using Multilevel Converters

    Författare :Faisal Altaf; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Thermal balancing; Convex optimization; DC-link ripple; Battery ripple; Battery control; Hybrid electric vehicles.; Multilevel converter; Cell balancing;

    Sammanfattning : Driven by the needs to reduce the dependence of fossil fuels and the emissions of conventional vehicles there has in recent years been an increasing interest in battery-powered electrified vehicles (xEVs). In xEVs, the battery pack, built from many small cells, is one of the most expensive components in the powertrain. LÄS MER
