Solid-phase microextraction (SPME) with a disposable ionic liquid (IL) coating was developed for headspace extraction of benzene, toluene, ethylbenzene, and xylenes (BTEX) in paints. The SPME fiber was coated with IL prior to every extraction, then the analytes were extracted and desorbed on the injection port of gas chromatography, and finally the IL coating on the fiber was washed out with solve

This article presents reasons for undertaking "The Comparative Study of the Prevention of Crime and Violence by Mentally Ill Persons" and reasons for decisions regarding the study design and choice of measures. A brief portrait of the forensic patients that have been recruited is also presented. Community treatment programs could offer long-term cost-effective care for offenders with major mental

Elater ferrugineus is a threatened click beetle inhabiting old hollow trees. Its larvae consume larvae of other saproxylic insects including the threatened scarab beetle Osmoderma eremita. Recently, (R)-(+)-gamma-decalactone was identified as a male-produced sex pheromone of O. eremita. Here we present evidence that E. ferrugineus adults use this odor as a kairomone for location of their prey. In

The purpose of this study is to contrast the forecasting performance of two non-linear models, a regime-switching vector autoregressive model (RS-VAR) and a recurrent neural network (RNN), to that of a linear benchmark VAR model. Our specific forecasting experiment is U.K. inflation and we utilize monthly data from 1969 to 2003. The RS-VAR and the RNN perform approximately on par over both monthly

A method for the determination of hexahydrophthalic acid, a metabolite of hexahydrophthalic anhydride, in human urine has been developed. The urine was worked-up by liquid-solid extraction, esterified with boron trifluoride-methanol, and analysed by capillary gas chromatography and selected-ion monitoring. Hexadeuterium-labelled hexahydrophthalic acid was used as the internal standard. The precisi

Backgrund: Nederman har ett långsiktigt mål att förbättra enheten i Helsingborg. Ett steg i detta är att se om det finns några förbättringar att genomföra i lagerstyrningen i form av lager- och servicenivåer. Detta då de anställda upplever dagens verktyg som ganska trubbiga för det nuvarande produktsortimenetet och att detta kanske kan förbättras genom ytterliggare en dimension på det befintliga sBackground: Nederman has a long term goal of improving their supply unit in Helsingborg. One step of this is to investigate if there are any improvements to be made in the inventory control in terms of stock levels and service level. This since the employees at Nederman believes that the existing methods are too blunt as a tool for the product range and that their methods can be improved by adding

The thesis attempts to assess the role of the OECD Commentaries in tax treaty interpretation process concluded between Non-OECD and OECD states. In order to reach the goal of the thesis the thesis discusses the legal status of the OECD Commentaries under public international law, in particular the interrelation of the Commentaries with the Articles of 31 and 32 of the Vienna Convention. The thesis

The main goal of this thesis is to determine to what degree can there be observed indications for an overvaluation of Internet companies, which in turn may lead to the next asset price bubble in the Internet industry. By conducting an ex-ante analysis, the current study sets out to add additional knowledge in regards to whether and how well the emergence of a bubble can be determined in advance. T

This thesis aims to analyze female sexual and bodily rights in Lebanon from a queer perspective, focusing on issues such as space and visibility and the strategically neglecting of historical existence of female narratives, referred to as conceptual anorexia. The thesis was preceded by a field work conducted in Beirut where observations of the field and interviews with LGBTQ- and/or feminist activ

The Water hyacinth is one of the worst aquatic weeds in the world and it is today present on all continents except Antarctica. It causes big problems for both people and the aquatic ecosystems in many countries. A lot of research has been completed to find methods to eradicate the weed and a lot of money has been spent on management to keep waters clean. In this literature study on management meth

Purpose: Gender dysphoria is commonly conceptualized as a mental disorder in gender-diverse people who do not identify with the gender assigned to them at birth. Direct support for well-being tends to be delegated to the field of mental health (MH), whereas speech-language pathology (SLP) practice is charged with modifying gender-diverse people's voice and communication in the belief that well-bei

Proteomics is widely utilized to understand the function of cellular processes at the molecular level. Using liquid chromatography interfaced with mass spectrometry (LC-MS)-based proteomics, thousands of proteins can be identified and quantified in a single experiment and their relationship and interactions can be analyzed. This makes the analysis of high-throughput proteomics data a cornerstone i

C4b binding protein (C4BP) regulates the complement system. It also interacts with anticoagulant protein S and with serum amyloid P component. Human C4BP is composed of seven identical 70-kDa alpha-chains and one 45-kDa beta-chain. The binding site for C4b is located on the alpha-chain, whereas the beta-chain binds protein S. Nothing is known about the structure and function of bovine C4BP. No com

While Raman spectroscopy provides opportunities for simultaneous detection and quantitative analysis of multiple species, it also suffers from certain limitations, such as low signal strength, which often makes it unsuitable for the study of minor species. The present work employs a high-repetition-rate and high-power laser and re-introduces an amplification technique to improve the detection limi

Background: Liver disease in Cystic Fibrosis (CFLD) is an early complication of CF. Evidence of CFLD is often subclinical and screening is recommended. Screening includes a biochemical work-up and an ultrasound investigation. Non-invasive methods measuring liver stiffness such as shear wave elastography could be beneficial. This study describes the use of 2D Shear Wave Elastography (2D SWE) in scr

A search is presented for the production of a single top quark via left-handed flavour-changing neutral-current (FCNC) interactions of a top quark, a gluon and an up or charm quark. Two production processes are considered: u+ g→ t and c+ g→ t. The analysis is based on proton–proton collision data taken at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. The data set correspond

Background: Inferior scapular notching is a complication unique to reverse shoulder arthroplasty. The most efficient technique to avoid inferior scapular notching has been reported to be lateralization of the glenoid offset. This study aims to compare radiological and functional outcomes of the DELTA Xtend® Reverse Shoulder System Lateralized Glenosphere Line Extension (intervention group) with th
