  1. 1. Fluorescent quantum dots and graphene-based sensors for forensic applications

    Author : Johnny Jussi; Ying Fu; Simon Dunne; Qin Wang; Ingemar Petermann; Xin Wang; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Graphene; Quantum Dots; Blood; Forensics; Drugs; Biological Physics; Biologisk fysik;

    Abstract : A key emerging concept within the forensic sciences today areportable measurementdevices, where a much more efficient usage of the resources involved with crime-solving is possible if confirmatory measurements can be realised directly at a crimescene with such devices. Today, the majority of the presently used methods duringcriminal investigation at a crime scene involves measurements of a presumptivenature, which is a vital tool as it enables the screening of samples.

  2. 2. Aspects of Moment Testing when p>n

    Author : Zhizheng Wang; Thomas Holgersson; Miguel Fonseca; Linnéuniversitetet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; High-dimensional data; Asymptotic distribution; Kolmogorov condition; Monte Carlo simulation; Hypothesis testing; Skewness and kurtosis; Statistics Econometrics; Statistik;

    Abstract : This thesis concerns the problem of statistical hypothesis testing for mean vector as well as testing for non-normality in a high-dimensional setting which is called the Kolmogorov condition. Since we consider mainly the first and the second moment in testing for mean vector and we utilize the third and the fourth moment in testing for non-normality, this thesis concerns a more general moment testing problem.

    Abstract : Inactivation of the p53 tumor suppre.ssor gene and activation of proto-oncogenes have been implicated in the initiation and/or progression of anumber of neoplasms. READ MORE

  4. 4. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution

    Author : Geng Wang; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; calorimetry; differntial scanning; isothermal titration; enthalpy; electrolyte; micelles; self-association; thermal gelling; interaction; alkyltrimethylammonium halides; sodium dodecylsulfate; surfactants; polymers; ethyl hydroxylethyl cellulose; viscosity; phase behavior; self-diffusion NMR; Physics; Fysik; Chemistry; Kemi; Fysicumarkivet A:1997:Wang;

    Abstract : The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. READ MORE

  5. 5. Expression and post-translational modification of purple acid phosphatase in insect and mammalian cells

    Author : Yunling Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Purple acid phosphatase (PAP) is an acidic metallohydrolase that contain a binuclear iron center in its active site. In mammals, this enzyme is also referred to as tartrate-resistant acid phosphatase (TRAPs), uteroferrin or type 5 acid phosphatase. READ MORE
