1. 21. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator

   Författare :Amir Sattari; Ivo Martinac; Mats Sandberg; Dirk Müller; KTH; []

   Sammanfattning : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. LÄS MER

3. 22. Classification of Potentially Unwanted Programs Using Supervised Learning

   Författare :Raja Muhammad Khurram Shahzad; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Malicious software authors have shifted their focus from illegal and clearly malicious software to potentially unwanted programs (PUPs) to earn revenue. PUPs blur the border between legitimate and illegitimate programs and thus fall into a grey zone. LÄS MER

4. 23. Immunocompromised Patients. Infections, Diagnostics and Nosocomial Transmission

   Författare :Anna Stjärne Asplund; Infektionsmedicin; []
   Nyckelord :;

   Sammanfattning : The aim of the work presented in this thesis was to improve the management of infections in immunocompromised patients by studying aspects of diagnostics, epidemiology and nosocomial transmission. Infection and rejection are common complications in lung-transplant patients, and early diagnosis and treatment are important for a positive outcome. LÄS MER

5. 24. Predictors of Lymph Node Metastasis in Primary Breast Cancer - Risk Models for Tailored Axillary Management

   Författare :Looket Dihge; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast Cancer; Axillary lymph node dissection; Sentinel lymph node biopsy; Ultrasonography; Nomogram; Artificial neural network; Gene Expression; Prediction model;

   Sammanfattning : Most patients with breast cancer present with low-risk tumors, node-negative disease, and excellent prognosis. For these patients, routine axillary nodal staging by sentinel lymph node biopsy (SLNB) has no therapeutic benefit. For patients with limited sentinel lymph node metastasis, completion axillary nodal dissection is controversial. LÄS MER

7. 25. Early detection of critical congenital heart defects in Sweden - with a focus on coarctation of the aorta

   Författare :Katarina Lannering; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; critical congenital heart defect; coarctation of the aorta; newborn; early detection; screening;

   Sammanfattning : Introduction: Despite the implementation of prenatal and neonatal screening, newborn infants with critical congenital heart defects (CCHD) remain at risk of being discharged undiagnosed, particularly newborns with coarcation of the aorta (CoA). Recent studies have suggested that perfusion index (PI) may potentially identify additional cases of CoA. LÄS MER
