  1. 1. Software Design Conflicts : Maintainability versus Performance and Availability

    Author : Daniel Häggander; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; object-oriented applications; design conflicts; performance; availability;

    Abstract : A major goal in software engineering is to reduce the cost of maintaining software systems. Finding design methods which make software more easily maintainable has thus been one of the most prioritized challenges during the past decade. While mainstream software design has concentrated on maintainability, other software disciplines e.g. READ MORE

  2. 2. Milk Folates: Characterisation and Availability

    Author : Karin Wigertz; Institutionen för livsmedelsteknik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; availability; ileostomy model; in vitro; HPLC; folate-binding protein; Milk; folates; Food and drink technology; Livsmedelsteknik;

    Abstract : With the ultimate goal to study milk folate bioavailability, a reverse-phase HPLC technique was developed and compared with a radioprotein binding assay. All methods showed similar ranges for folates in cow’s milk, with the variation attributed to seasonal variations and the use of different starter cultures. READ MORE

  3. 3. Co-firing animal waste, sludge, residue wood, peat and forest fuels in a 50MWth CFB boiler : ash transformation, availability and process improvements

    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Co-combustion; animal waste; peat; waste wood; forest residues; industrial sludge; limestone; CFB boiler; ash transformation; corrosion; erosion; ash and deposit characteristics; deposit buildup; boiler failures; availability; sulfation; boiler design; boiler conversion; waste derived fuels; large scale; Samförbränning; animaliskt avfall; torv; returträ; skogsbränsle; reningsslam; askomvandling; korrotion; erosion; ask- och beläggnings-karaktäristik; beläggningstillväxt; tillgänglighet; sulfatisering; panndesign; pannkonvertering; avfallsderiverade bränslen; storskalig;

    Abstract : The direct variable costs for heat and electricity production based on solid biomass fuel combustion is approximately 3-5 times lower than the costs in a fossil fuel-oil based boiler in Sweden. In addition waste derived biomass fuels are typically much cheaper than biomass not classified as waste. READ MORE

  4. 4. Performance, Availability, and Scalability in Open Networking Platforms for Internet Services

    Author : Voravit Tanyingyong; Peter Sjödin; Markus Hidell; Raimo Kantola; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network architecture and design; Network communications; Performance; Availability; Scalability; Internet of Things IoT ; Nätverksarkitektur och design; nätverkskommunikation; prestanda; tillgänglighet; skalbarhet; sakernas internet IoT ; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Advancement in technologies brings about new demands and services. In parallel, modern commodity off-the-shelf (COTS) hardware has become very capable yet affordable. It is often used in combination with Free/Libre and Open Source Software (FLOSS) to build open networking platforms, which offer alternatives to commercial network devices. READ MORE

  5. 5. Characterization of PAH-contaminated soils focusing on availability, chemical composition and biological effects

    Author : Magnus Bergknut; Mats Tysklind; Dag Broman; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; polycyclic aromatic hydrocarbons; PAHs; availability; bioavailability; chemical analysis; characterization; GC-TOFMS; bioassay; toxicity; biological testing; multivariate methods; PCA; PLS; Environmental chemistry; Miljökemi;

    Abstract : The risks associated with a soil contaminated by polycyclic aromatic hydrocarbons (PAHs) are generally assessed by measuring individual PAHs in the soil and correlating the obtained amounts to known adverse biological effects of the PAHs. The validity of such a risk estimation is dependent on the presence of additional compounds, the availability of the compounds (including the PAHs), and the methods used to correlate the measured chemical data and biological effects.
