  4. 2. Acute Lymphoblastic Leukaemia in Adult Patients : Studies of Prognostic Factors, Treatment Results and in vitro Cellular Drug Resistance

    Author : Helene Hallböök; Bengt Smedmyr; Elin Lindhagen; Lorentz Brinch; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; acute lymphoblastic leukaemia; adult; adolescent; chemotherapy; stem cell transplantation; in vitro assay; imatinib; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Abstract : Treatment results and clinical characteristics in adult acute lymphoblastic leukaemia (ALL) were evaluated regarding three issues: a new treatment with cytarabine up-front, stem cell transplantation and a comparison between adult and paediatric treatment protocols. All studies were conducted on a national basis. READ MORE

  5. 3. Forever Young : Convolution Inequalities in Weighted Lorentz-type Spaces

    Author : Martin Křepela; Sorina Barza; Javier Soria; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Convolution; Young inequality; Lorentz spaces; weights; rearrangement-invariant spaces; Matematik; Mathematics;

    Abstract : This thesis is devoted to an investigation of boundedness of a general convolution operator between certain weighted Lorentz-type spaces with the aim of proving analogues of the Young convolution inequality for these spaces.Necessary and sufficient conditions on the kernel function are given, for which the convolution operator with the fixed kernel is bounded between a certain domain space and the weighted Lorentz space of type Gamma.

  6. 4. Relations between functions from some Lorentz type spaces and summability of their Fourier coefficients

    Author : Aigerim Kopezhanova; Natasha Samko; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lorentz spaces; Fourier series; Inequalities; Mathematics; Matematik; Mathematics; Matematik;

    Abstract : This Licentiate Thesis is devoted to the study of summability of the Fourier coefficients for functions from some Lorentz type spaces and contains three papers (papers A - C) together with an introduction, which put these papers into a general frame.Let $\Lambda_p(\omega),\;\; p>0,$ denote the Lorentz spaces equipped with the (quasi) norm$$\|f\|_{\Lambda_p(\omega)}:=\left(\int_0^1\left(f^*(t)\omega(t)\right)^p\frac{dt}{t}\right)^{\frac1p}$$for a function $f$ on [0,1] and with $\omega$ positive and equipped with some additional growth properties.

  7. 5. Summability of Fourier transforms of functions from Lorentz spaces

    Author : Aigerim Kopezhanova; Lars-Erik Persson; Peter Wall; Erlan Nursultanov; Mikhael Goldman; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : This PhD thesis is devoted to the study of relations between integrability properties of functions and summability properties of its Fourier coefficients and transforms. The relations are given in terms of generalized weighted Lorentz norms, where the weights have some additional growth properties. READ MORE
