This book comprises the select proceedings of the International Conference on Future Learning Aspects of Mechanical Engineering (FLAME 2020). This volume focuses on current research in fluid and thermal engineering and covers topics such as heat transfer enhancement and heat transfer equipment, heat transfer in nuclear applications, microscale and nanoscale transport, multiphase transport and phas
Glaucoma is a potentially blinding disease where the affected individual often firstnotices symptoms when the disease has reached a late stage. If glaucoma is detectedearly e.g., at screening, the risk for visual impairment can be reduced. There are manyfactors that affect a patient´s risk of developing glaucoma or visual impairment due toglaucoma. In the four studies of this thesis, the general a
The authors of this paper reinvestigate the remains of the Basilica Sempronia, situated below the Imperial Basilica Julia in Rome. By combining the information from the original excavation with a new 3D digital documentation, new observations are made and previous interpretations reassessed. The present remains are discussed in relation to the contemporary built environment, as well as to precedin
Episodes of economic shrinking have declined since the 1980s in Latin America and the Caribbean (LAC). This paper asks why. We propose that the reduction in the frequency and rate of shrinking reveals the dynamic transition from being natural states towards becoming open access societies. To provide empirical support to the argument, we rest on the notion of social capabilities. Hence, societies t
Experimental field measurements regarding airtightness following the fan pressurisation method were done on 25 typical residential buildings at different locations in Nepal. The field measurement data were classified according to building type and building age.The mean air permeability (Q50 ) for the studied buildings was 6.9 l/s·m2 and the mean air change rate was 55.5 air changes per hour at 50
The adsorption of organic micropollutants onto powdered activated carbon (PAC) was investigated in laboratory scale based on samples from four wastewater process streams (matrices); three from a pilot-scale plant with different degrees of physicochemical treatment of municipal wastewater and one from a full-scale activated sludge plant with post-precipitation. The pilot-scale treatment consisted o
Populärvetenskaplig sammanfattningAvloppsvatten med läkemedelsrester renas med filter och aktivt kolVA-bolagen står inför flera utmaningar vad gäller rening av avloppsvatten. Till exempel att minska energianvändningen på reningsverken, samt att rena avloppsvattnet från läkemedelsrester. I den här studien har olika typer av filtrering i kombination med aktivt kol testats med målet att rena från läkPharmaceutical residues and other organic micropollutants are transported via municipal wastewater to wastewater treatment plants (WWTPs). However, current treatment processes are not designed to remove organic micropollutants, and several such compounds have been found in recipients, where they can have negative effects on aquatic organisms. Additional processes are therefore required to reduce t
Background: Severe alpha-1-antitrypsin deficiency (AATD) is a genetic condition predisposing to chronic obstructive pulmonary disease (COPD) and liver disease. Its natural course is not well known. Our aim was to study the natural course of AATD by analyzing the clinical course in individuals with severe AATD identified by screening.Materials and Methods: Of the 1585 individuals included in the Sw

The electronic band structure of complex nanostructured semiconductors has a considerable effect on the final electronic and optical properties of the material and, ultimately, on the functionality of the devices incorporating them. Valence electron energy-loss spectroscopy (VEELS) in the transmission electron microscope (TEM) provides the possibility of measuring this property of semiconductors w
In recent years, assessment of sediment contamination by heavy metals, i.e., arsenic, has attracted the interest of scientists worldwide. The present study provides a new methodology to better understand the factors influencing surface water vulnerability to arsenic pollution by two advanced machine learning algorithms including boosted regression trees (BRT) and random forest (RF). Based on the s
We engineer a system of two strongly confined quantum dots to gain reproducible electrostatic control of the even-electron spin at zero magnetic field. Coupling the dots in a tight ring-shaped potential with two tunnel barriers, we demonstrate that an electric field can switch the electron ground state between a singlet and a triplet configuration. Comparing our experimental cotunneling spectrosco
The extremely small feature size and total sample volume of semiconductor nanowire materials has meant that advanced techniques have been required for even the most routine sample characterization since the structures were first reported. Electron microscopy has been the technique of choice for fast and reliable determination of nanowire morphology, structure, and composition since the earliest re
