Cyklometallering är en reaktion som används i alltifrån tillverkning av nya material till katalys av industriella kemiska processer, så att de sker snabbare och energisnålare. I denna reaktion reagerar en metall med en organisk molekyl (en ligand) och bildar en cykel och en ny metall-kolbindning. En typ av komplex som bildas genom cyklometallering är pincer-komplex, och dessa komplex kan bland annCyclometallation reactions and pincer complexes are both essential in organometallic synthesis and catalysis. The C-H bond activation is a key step in cyclometallation and metallacycles such aspincer complexes can thus be used to study this bond activation event. Much research has been conducted on the PCsp2P pincer complexes and their cyclopalladations, but not as much on their analogous sp3-hybr

This thesis explores the anti-media populist discourse of the current Slovak Prime Minister Robert Fico, with which he harshly targets Slovak mainstream media to delegitimize them and their critical reporting. This practice, which Fico has been engaging in for many years, was originally considered problematic mainly due to its potentially detrimental consequences for trust in the media among many

Bakgrund: Personer med psykisk ohälsa upplever ofta svårigheter med sensorisk bearbetning, vilket kan påverka aktivitetsförmåga och livskvalitet negativt. Sensorisk modulering har nyligen introducerats som en positiv metod inom vuxenpsykiatrisk verksamhet i Sverige, men arbetsterapeuters kunskap och användning av metoden inom primärvården är ännu outforskad. Syfte: Att undersöka arbetsterapeutersBackground: Individuals with mental health problems often experience difficulties with sensory processing, which can negatively affect their ability to engage in activities and reduce quality of life. Sensory modulation has been introduced as a promising approach in adult psychiatric care in Sweden, but occupational therapists' knowledge and application of this method in primary health care re

This thesis investigated the potential of using reactive power compensation to solve overvoltage issues caused by high amounts of distributed generation, such as rooftop photovoltaic (PV) systems, in the low voltage grid. High voltages are caused by increasing distributed generation as the Swedish power grid shifts from centralised to decentralised power production. The aim was to manage overvol

Utvecklingen av autonoma fartyg (‘MASS’) innebär betydande utmaningar för det befintliga systemet för sjörättsligt ansvar. Culpabaserat ansvar och begreppet vårdslöshet är traditionellt uppbyggda kring bedömningen av mänskligt handlande, beslutsfattande och kontroll. Detta väcker frågor om huruvida vårdslöshet och culpa fortfarande är begreppsmässigt sammanhängande när operativa beslut fattas av aThe development of Maritime Autonomous Surface Ships (‘MASS’) presents significant challenges to the existing framework of maritime liability law. Fault-based liability and the concept of negligence are traditionally structured around the assessment of human conduct, decision-making and control. This raises the question of whether negligence and fault remain conceptually coherent where operational

We investigated return of spontaneous circulation and of cerebral oxygenation after asphyxia-induced cardiac arrest, using ventilation with air, throughout, or with 100% oxygen for a shorter or longer period. Arterial pressure, heart rate, regional cerebral oxygen saturation (CrSO2) and brain tissue oxygen tension (PbtO2) were measured in one day old piglets that were hypoventilated with air and l

Background:In Lynch syndrome, inherited mismatch repair (MMR) defects predispose to colorectal cancer and to a wide spectrum of extra-colorectal tumours. Utilising a cohort study design, we aimed to determine the risk of extra-colorectal cancer and to identify yet unrecognised tumour types.Methods:Data from 1624 Lynch syndrome mutation carriers in the Danish hereditary non-polyposis colorectal can

AbstractPURPOSE: To assess the relative influence of genetic and environmental factors on optic disc size and cup/disc ratio in healthy eyes. METHODS: A sample of 55 monozygotic and 50 dizygotic healthy twin pairs aged 20-46, all having the same sex within pairs (47 pairs were male) had optic discs measured from colour fundus photographs according to the Wisconsin Protocol. Structural equation mod

Introduction: Lactic acid bacteria (LAB) play an important role in the food industry as starter cultures to manufacture fermented food, and as probiotics. In recent years, there has been an increasing interest in using LAB cultures for biopreservation of food products. It is therefore of great interest to study the detailed metabolism of these bacteria. Objectives: This study aimed at developing a

The PI3K/mTOR pathway is the second most frequently deregulated pathway in a majority of cancers such as breast cancer, lung cancer, and melanomas as well as leukemia. Mutations in the genes coding for receptor tyrosine kinases (RTKs) and G-protein-coupled receptors (GPCRs) are quite common in all forms of acute leukemia. This can be a major cause of deregulation of the PI3K-mTOR pathway. To under

The entropy generation analysis of fully-developed turbulent heat transfer flow in inward helically corrugated tubes was numerically performed by using a Reynolds stress model. The simulations were conducted for a smooth tube and five cases of corrugated tubes with Reynolds number (Re) ranging from 10,020 to 40,060 at a constant wall temperature condition. The effects of corrugation pitch and heig

European emission legislation has in recent years put a strict limit on NOx emissionsfrom heavy-duty truck engines. EGR and selective catalytic reduction are the two mostcommon technologies applied in a modern heavy-duty diesel engine to fulfill the legislation.The scope of this thesis is to explore other ways of reducing NOx emissions emittedby a heavy-duty engine. Several technology options are

The aim was to investigate clinical predictors of adherence to antipsychotics. Medication use was electronically monitored with a Medication Event Monitoring System (MEMS(®)) for 12 months in 112 outpatients with schizophrenia and schizophrenia-like psychosis according to DSM-IV. Symptom burden, insight, psychosocial function (PSP) and side effects were rated at baseline. A comprehensive neuropsyc

Background Abiraterone acetate (AA) prolongs survival in metastatic castration-resistant prostate cancer (mCRPC) patients. To measure treatment response accurately in bone, quantitative methods are needed. The Bone Scan Index (BSI), a prognostic imaging biomarker, reflects the tumour burden in bone as a percentage of the total skeletal mass calculated from bone scintigraphy. Objective To evaluate

Background: Many endoscopists acknowledge that the appearance of the papilla of Vater seems to affect biliary cannulation. To assess the association between the macroscopic appearance of the papilla and biliary cannulation and other related clinical issues, a system is needed to define the appearance of the papilla. Objective: The purpose of this study was to validate an endoscopic classification

Objective The aim of this study was to explore the relation between the risk of first-ever stroke at working age and psychological work environmental factors. Methods A consecutive multicenter matched 1:2 case-control study of acute stroke cases (N=198, age 30-65 years) who had been working full-time at the time of their stroke and 396 sex- and age-matched controls. Stroke cases and controls answe

Nutrient availability is of major importance for plant productivity. When estimating long-term sustainability from a nutrient perspective it is therefore interesting to focus on long-term changes in the soil nutrient pools when comparing different forest types. Here, we have highlighted some factors of importance for long term nutrient sustainability (e.g., several forest rotations) and pointed ou
