Temperature and coagulant types have an important impact on the quantity and quality of the residue (sludge) in water and wastewater treatment processes. Temperature influences water viscosity and the distribution of the coagulant in water. Coagulants can promote the agglomeration of fine particles into larger flocs so that they can be more easily separated from the water. Experiments have been co

Objective To determine if patients with systemic lupus erythematosus (SLE), a disease characterised by elevated type I interferons reminiscent of anti-viral immunity, have expression of human endogenous retrovirus K (HERV-K) proviruses capable of producing envelope (Env) protein, as well as associated autoantibodies against the Env protein. Methods ELISAs were conducted with recombinant Env protei

Core-shell nanoparticles have gathered much attention of the scientific community owing to their potential applications in various fields including biomedical imaging and catalysis. Predicting core-shell preference1-3 is, however, still largely based on a few experimental observations and limited theorical studies, and hence development of new core-shell nanoparticles is normally built on a trial-

We report multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction calculations on the thallium (Tl) electron affinity, as well as on the excited energy levels arising from the ground configuration of Tl-. The results are compared with the available experimental values and further validated by extending the study to its homologous, lighter element, indium (In), belonging to

BACKGROUND: The presence of an apolipoprotein E4 (ApoE4) genotype is the major genetic risk factor for Alzheimer's disease (AD). Astrocytes are the main source of ApoE in the brain, however ApoE can also be produced by neurons and microglia. ApoE plays a role in many cell types and processes related to AD, however, it remains unclear which mechanism(s) and cellular source of ApoE are most critical

A search for a heavy neutral Higgs boson, A, decaying into a Z boson and another heavy Higgs boson, H, is performed using a data sample corresponding to an integrated luminosity of 36.1 fb−1 from proton–proton collisions at s=13 TeV recorded in 2015 and 2016 by the ATLAS detector at the Large Hadron Collider. The search considers the Z boson decaying to electrons or muons and the H boson into a pa

We used the nationwide Swedish Family-Cancer Database with 2060 childhood brain tumours diagnosed in the period 1958-1996 to analyse the risk of this tumour by parental cancers and in siblings of childhood brain tumour probands. Groups of patients were compared by calculating standardized incidence ratios (SIRs) for brain tumours in offspring. 1.3% of brain tumour patients had a parent with nervou

Objective: We sought to examine changes in regional and sex disparities in stunting, thinness, and overweight among Chinese school-aged children from 1985 to 2014. Methods: We analyzed data on 1,489,953 children aged 7–18 years in the Chinese National Survey on Students’ Constitution and Health. Stunting, thinness, and overweight were defined according to WHO anthropomorphic definitions. After adj

Background: Metastatic castration resistant prostate cancer (mCRPC) is a bone dominant lethal disease. Progression in bone scan of mCRPC disease is assessed with the Prostate Cancer Working Group (PCWG) two and three criteria, which relies on the appearance of two or more new lesions. There is an unmet need for a quantitative assessment that can build on the current progression criteria. This thes

Measuring the temperature below the surface of a thermal barrier coating (TBC) using a thin phosphor layer is challenging primarily due to the absorption and scattering of laser excitation light and phosphor luminescence as they propagate through the coating. One way to increase phosphor luminescence could be to use upconversion phosphor thermometry, which is investigated in the current study. It

The use of a semi-empirical alternative to the standard Washburn equation for the interpretation of raw mercury porosimetry data has been advocated. The alternative expression takes account of variations in both mercury contact angle and surface tension with pore size, for both advancing and retreating mercury meniscii. The semi-empirical equation presented was ultimately derived from electron mic

INTRODUCTION: Opioid use disorder (OUD) is the leading cause of overdose morbidity and mortality globally. Retention in opioid agonist treatment (OAT) is crucial as it effectively reduces overdose mortality among individuals suffering from OUD. Previous research on treatment retention among heroin-dependent individuals referred from needle exchange programs (NEP) to OAT is scarce, and with predict

Vikten av resurseffektivitet i livsmedelskedjan är tydlig, eftersom denna sektor är en av de största bidragarna till negativ klimatpåverkan globalt. Målet med den här uppsatsen var att utforska sidoströmmar av mat inom livsmedelskedjan i Västra Götaland, för att kartlägga hur mycket som redan är täckt i statistiken och vilka luckor i datamaterialet som finns för framtida forskning att täcka. DessThe importance of resource efficiency in the food supply chain is clear, since this sector is one of the biggest contributors to the negative environmental impacts globally. This thesis project aimed to examine food side streams throughout the food supply chain in Västra Götaland, to map out how much has already been covered statistically and what gaps there are in the data for future research to

The aim of this study was to examine if there is a co-variation between attachment styles towards a parental figure and towards a partner. To investigate this, we used a quantitative self-assessment questionnaire, the Revised Adult Attachment Scale (RAAS) (1996). We wanted to investigate if such a questionnaire can measure something as complex as attachment. With a quantitative method based on the

The aim of this qualitative study is to investigate social services managers' expectations and experiences of social services consultants. This study focuses on managers for children and young people in social services. The method used in the survey was semistructured interviews with six managers, who has had at least one consultant in their working group. To analyze our results, we have used

This master’s dissertation has been performed in cooperation with Tyréns and the Dept. of Construction Sciences, LTH. We have investigated if it is possible to increase the total stability for excavations with retaining structures and if each side of an excavation could be treated as a separate 2D-case with additional theories to approximate its 3D-effects. End-surface theories from the Commissio

Expertskattereglerna i 11kap 22-23 a §§ IL tillkom för att underlätta rekryteringen av utländska experter på sådan kompetensnivå att svårigheter föreligger för rekrytering inom landet. Syftet med införandet av lagstiftningen var att attrahera nyinvesteringar till Sverige efter att Sveriges konkurrenskraft stadigt minskat på grund av att liknande skattelättnader funnits hos de europeiska grannländeThe tax relief legislation for foreign key personnel in chapter 11 article 22-23a of the Income Tax Act was adopted to ease the recruitment of foreign key personnel to Sweden. The aim of the tax relief legislation was to provide additional advantage to companies who needed foreign expertise to their Swedish operations. This thesis will discuss the case law developed mainly by the County Administra

Neural networks are effective for solving many complex human-level tasks, one type of neural network often used in imaging tasks is the convolutional neural network (CNN). They can effectively solve problems in areas like image recognition, object detection, and classification tasks. Using a CNN for one of these tasks requires a huge computational cost relative to what a typical algorithm would ha

Spatial relationships are a comprehensive and essential part of geographical information management and GIS. Topological relationships are a subgroup of the spatial relationships. They are defined by the fact that they do not break under topological transformations, meaning they remain when stretching, twisting or crumbling the underlying space. Topological relationships are for instance relations
