Massive MIMO has attracted many researchers’ attention as it is a promising technology for future 5G communication systems. To characterize the propagation channels of the massive MIMO and to evaluate system performance, it is important to develop an accurate channel model for it. In this thesis, two correlative models, i.e., the Kronecker model and the Weichselberger model, and a cluster-based m
Homografts have long been used for right ventricular outflow tract (RVOT) reconstruction. Tissue banks struggle to meet the clinical demand of tissue, with insufficient donor availability and strict recommendations on tissue quality with high proportions of discards. This study analyzes the long-term outcome of patients receiving a homograft with small fenestrations of the cusps or other structura
Background: Treatment of chronically occluded infrainguinal venous bypass grafts in patients presenting with recurrent chronic limb threatening limb ischemia (CLTI) represent a clinical challenge. Recent case reports have suggested the use of endovascular recanalization techniques without preceding thrombolysis. This study assesses feasibility and mid-term outcomes of this technique. Results: A re
Objective: To assess the value of second-look resection (SLR) in stage T1 bladder cancer (BCa) with respect to progression-free survival (PFS), and also the secondary outcomes recurrence-free survival (RFS), bladder-cancer-specific survival (CSS), and cystectomy-free survival (CFS). Patients and methods: The study included 2456 patients diagnosed with stage T1 BCa 2004–2009 with 5-yr follow-up reg
Background: Patients in intensive care units (ICUs) are among the most vulnerable, and they require support to start their recovery. The design of the patient area in the ICU can play a prominent role in both the quality of care and patients’ recovery. The lighting environment has the opportunity to restore and strengthen the natural human circadian rhythm and health. Aim: To evaluate patients’ se
Sialylations are post-translational modifications of proteins and lipids that play important roles in many cellular events, including cell-cell interactions, proliferation, and migration. Tumor cells express high levels of sialic acid (SA), which are often associated with the increased invasive potential in clinical tumors, correlating with poor prognosis. To overcome the lack of natural SA-recept
A common problem when studying groundwater contamination in low-income countries is that data required for a detailed risk assessment are limited. This study presents a method for assessment of the potential impact of groundwater contamination by total petroleum hydrocarbons (TPH) in a data-scarce region. Groundwater modeling, using the MODFLOW, was used to simulate regional-scale flow pattern. Th
Background The aim of the study was to evaluate how different parameters in the preoperative, perioperative, and postoperative period affect time to full enteral feeding (TFEF) in children undergoing pyloromyotomy. Methods A retrospective study of all children operated for infantile hypertrophic pyloric stenosis between 2001 and 2017 was conducted. Parameters in demographics and in the preoperativ
Detta är en debattartikel. Det är skribenten som står för åsikterna som förs fram i texten, inte Aftonbladet.För det första behöver konsumtionen av animalisk föda minska. Detta minskar utsläppen av den kraftfulla växthusgasen metan som idisslare producerar, skriver Henrik Smith, professor i zooekologi.
Nemo-like kinase (NLK) is a member of the mitogen-activated protein kinase family of kinases and shares a highly conserved kinase domain with other mitogen-activated protein kinase family members. The activation of NLK contributes to the pathogenesis of Diamond–Blackfan anemia (DBA), reducing c-myb expression and mechanistic target of rapamycin activity, and is therefore a potential therapeutic ta
The continued increased exposure to chemicals and the increasing prevalence of allergic contact dermatitis makes it important to develop accurate testing methods and strategies to assess chemical sensitizers. The Genomic Allergen Rapid Detection (GARD) assay is an in vitro test method that uses the transcriptional response of a myeloid cell line, MUTZ-3, after exposure to test substances to assess
To utilize sugars as a feedstock for renewable industries, the feedstock often needs to be very pure. This is due to ionic species contaminating the sugar feedstock being potent catalyst poisons in many cases. To remove ionic species from the sugar feedstock, it is dissolved and purified using packed ion-exchange columns. In this report, a lab-scale setup of a large scale ion-exchange setup was co
Digitaliseringen har revolutionerat våra samhällen. Hur vi kommunicerar och interagerar med varandra och hur vi handlar produkter och tjänster har över de senaste åren varit föremål för drastiska förändringar. Bakom dessa förändringar står ett fåtal digitala jättar. Trots att förändringarna har ökat konsumentvälfärden och i regel varit positiva, har farhågor lyfts. Detta har inte minst uppmärksammDigitalization has revolutionized our societies. How we communicate and interact with one another and how we purchase goods and services has changed drastically. A select few technological giants are the driving force behind these changes. Despite the increase in consumer welfare and the overall heightened standard of living, concerns have been raised, especially within the discourse of competitio
Thesis purpose: This research investigates the effect of six specific consumers’ characteristics, i.e. fashion leadership, shopping enjoyment, instrumental and terminal materialism, green selfidentity, and social influence susceptibility, on consumers’ attitude towards a product-service system (a use-PSS) in the form of second-hand clothing rental. The relationship between attitude and consumers’
This project was done for the company Beijer Electronics Products AB and the task was given by the hardware development department of the company. The project was about developing a concept proposal for a new generation operator panels. This was done to inspire the product developers at Beijer Electronics with innovative ideas before the actual operator panel development. More in detail the object
