  1. 1. Direct Demonstration of Influenza Virus and Mycoplasma Pneumoniae in the Respiratory Tract

    Författare :Anna Nilsson; Enheten för infektionssjukdomar; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polymeras chain reaction; influenza virus; Mycoplasma pneumoniae; diagnosis; respiratory tract infection; sample site; serial samples;

    Sammanfattning : Diagnostic tests based on nucleic acid amplification have become available for Mycoplasma pneumoniae (MP) and influenza viruses. Here, an MP PCR test detected 100% of infections during the first three symptomatic weeks, whereas classical serology detected 21% week 1, 56% week 2, and 100% week 3. LÄS MER

  3. 2. On-site sanitation systems - An integrated assessment of treatment efficiency and sustainability

    Författare :Brenda Vidal; Annelie Hedström; Inga Herrmann; Arve Heistad; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; small-scale; sand filter; phosphorus filter; package plant; blackwater; greywater; urine diversion; multi-criteria; composite sample; VA-teknik; Urban Water Engineering;

    Sammanfattning : Small on-site sanitation systems for wastewater collection and treatment are prevalent in suburban and rural areas in many countries. However, these systems often underperform, causing potential impact to the receiving waters and increasing the risks to public health, thus hindering the overall sustainability of the systems.

  4. 3. Finding fitness : empirical and theoretical explorations of inferring fitness effects from population-level SNP data

    Författare :Bea Angelica Andersson; Xiao-Ru Wang; Åke Brännström; Tanja Slotte; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distribution of fitness effects; site frequency spectra; missing data filtering; downsampling; imputation; sample size; population structure; inbreeding; selfing; homozygosity; Arabidopsis; Pinus; DFE-alpha; SLiM; population genomics; adaptation; biology; biologi; evolutionär genetik; evolutionary genetics; populationsbiologi; Population Biology; molekylärbiologi; Molecular Biology; Genetics; genetik;

    Sammanfattning : The distribution of fitness effects (DFE) describes the likelihood that a new mutation has a specific effect on the fitness of an individual in a given population. The shape of the DFE is a result of several factors such as population size, mating system and selective environment, and can in turn influence the evolutionary potential of a species. LÄS MER

  5. 4. On-Site Sampling in Economic Valuation Studies

    Författare :Termeh Shafie; Thomas Laitila; Stockholms universitet; []
    Nyckelord :Sample inclusion; Length-bias; Poisson dis- tribution; ML-estimation; Bivariate ordered probit; CVM.; Statistics; statistik;

    Sammanfattning : A commonly used sampling design in economic valuation studies is on-sitesampling. If this sampling design is used, the sampling inclusion probabil-ities may be correlated with respondents’ valuations, invalidating welfaremeasures derived from estimates of the probit model.

  7. 5. Sample preparation and mass spectrometry in proteome studies

    Författare :Daniel Hirschberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Proteome studies aim to link gene to function. Instead of screening for function in a specific protein as in classical protein chemistry, proteins are now screened against a specific phenotype, disease or metabolic state. LÄS MER
