Exposure to Paracetamol in Early Pregnancy and the Risk of Developing Cerebral Palsy : A Case-Control Study Using Serum Samples

OBJECTIVE: To investigate whether maternal paracetamol use in early pregnancy is associated with cerebral palsy (CP) in offspring.STUDY DESIGN: We conducted a registry and biobank-based case-control study with mother-child pairs. We identified CP cases (n=322) born between 1995-2014 from a nationwide CP-registry. Randomly selected controls (n=343) and extra preterm controls (n=258) were obtained f

Utvärdering av olika farthinder på Lunds huvudgator utifrån bussarnas perspektiv - En jämförelsestudie

Varje år sker en ökande urbanisering och med fler människor i en stad så ökar trafikbelastning och därmed risken för olyckor. Därför är det viktigt att kommunerna arbetar med att skapa trafikmiljöer som är säkra för gående, cyklister, bilister och kollektivtrafiken. Trafiksäkerhet och komfort är två viktiga parametrar att arbeta med eftersom dessa de bidrar till de transportpolitiska målen och nolEvery year there is an increasing urbanization and traffic load, which means that we have to create traffic environments that are safe for pedestrians, cyclists, vehicles and public transport. Traffic safety and comfort are two important parameters that are worked with, and the aim is to increase traffic safety and comfort which contribute to the transport policy goals and the zero vision where no

Photoluminescence Studies of Polytype Heterostructured InP Nanostructures

The interface between two semiconductors significantly influences their optical and electronic properties. In contrast to traditional material heterostructures, polytype heterostructures between wurtzite (wz) and zincblende (zb) segments in homomaterial InP nanostructures exhibit sharp interfaces with minimal strain. The wz/zb interface of heterostructured InP has a type-II band alignment, which r

Synthesis towards an aromatic alfa-dixyloside

A proteoglycan is a protein with at least one glycosidic chain or glycosaminoglycan (GAG) covalently bound to it. Since a common linker between the core protein and the GAG chain has a xylose present, the biosynthesis of GAGs can be primed using xylosides containing hydrophobic aglycons providing that these xylosides are capable of penetrating the cell membrane. 2-naphthyl β-D-xylopyranoside prim

C-H activation with heterogenous N-Heterocyclic palladium complexes: Synthesis and Evaluation of ligand-directed catalysis

C-H activation with transition metal catalysts is one the most intense areas of research today and new advancements aid in the production of bulk chemicals, simplifying synthetic routes and transforming inert substrates into functionalized ones. By attempting to synthesize two N- heterocyclic palladium complexes (1 and 2, complex 3 is received) heterogenous, ligand- directed halogenation of substr

Berättelser om verkligheten : från magnetband till mp3

Swedish public service radio has during its almost 100 years undergone several transformations due to technical, societal and cultural changes. A transformation still in motion can be attributed to the arrival of the internet, the digitalization of the recording, storage and distribution of sound, as well as the fast paced evolution of the global media landscape. When the mp3-file and the internet

An online learning analysis of minimax adaptive control

We present an online learning analysis of minimax adaptive control for the case where the uncertainty includes a finite set of linear dynamical systems. Precisely, for each system inside the uncertainty set, we define the model-based regret by comparing the state and input trajectories from the minimax adaptive controller against that of an optimal controller in hindsight that knows the true dynam

Automated tight Lyapunov analysis for first-order methods

We present a methodology for establishing the existence of quadratic Lyapunov inequalities for a wide range of first-order methods used to solve convex optimization problems. In particular, we consider (i) classes of optimization problems of finite-sum form with (possibly strongly) convex and possibly smooth functional components, (ii) first-order methods that can be written as a linear system on

Integrability of a Globally Coupled Complex Riccati Array : Quadratic Integrate-and-Fire Neurons, Phase Oscillators, and All in between

We present an exact dimensionality reduction for dynamics of an arbitrary array of globally coupled complex-valued Riccati equations. It generalizes the Watanabe-Strogatz theory [Integrability of a globally coupled oscillator array, Phys. Rev. Lett. 70, 2391 (1993).PRLTAO0031-900710.1103/PhysRevLett.70.2391] for sinusoidally coupled phase oscillators and seamlessly includes quadratic integrate-and

Lagen som ett retoriskt objekt - En analys av gamla och nya konsumentköplagen

Arbetet ämnar ge ett teoretiskt perspektiv på utformningen av det svenska lagspråket. Genom en retorisk argumentationsanalys, grundad i Chaïm Perelmans teori om föreställda publiker och Lloyd Bitzers teori om den retoriska situationen, utreds konsumentlagstiftningen i sin egenskap som meningsbärare mellan en retorisk avsändare och en retorisk mottagare. Den gamla och den nya konsumentköplagen jämfThe thesis aims to provide a theoretical perspective on the language used in the Swedish law. Through a rhetorical argumentation analysis, grounded in Chaïm Perelman’s theory of perceived audiences and Lloyd Bitzer’s theory of the rhetorical situation, the consumer sales act is investigated in its capacity as a carrier of meaning between a speaker and an audience. The old and the new consumer sale

Photoperiodic response of body mass gain in migratory juvenile European pied flycatchers (Ficedula hypoleuca)

Climate change forces organisms to adapt to new habitats with migratory birds facing unique challenges, especially when they initiate the migratory behaviour to gain mass for migration. Many bird species adapt to their ancestral latitudes by changing their behaviour and physiology to the photic environment. Current predictions indicate that climate change can also limit range shift capacity due to

Propagation losses in BaTiO3-based waveguides on silicon

Integrated silicon photonics is emerging as the most promising route for interconnects and on-chip com- munication to keep up with the constant performance increase of CMOS (complementary metal oxide semiconductor) technology. Among the components of integrated photonics, the electro-optic modulators implemented on silicon are suffering from high insertion losses and high power consumption. Due to

Development and Evaluation of an Enzyme-Based Sunscreen

Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. By introducing an enzyme-based sunscreen for daily facial use these damages may be reduced while also providing exfoliation and hydration

Flow of charged particles in Pb-Pb and pp collisions at the LHC

This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. Collective behavior, indicating a QGP phase, is studied through anis

Amidst an amygdala renaissance in Alzheimer's disease

The amygdala was highlighted as an early site for neurofibrillary tau tangle pathology in Alzheimer's disease in the seminal Braak & Braak article (1991). This knowledge has, however, only received traction recently with advances in imaging and image analysis techniques. Here, we provide a cross-disciplinary overview of pathology and neuroimaging studies on the amygdala. These studies provide

Avian Malaria in the Scandinavian Mountains from 1999 to 2020

This study investigates and describes the Haemosporidian parasite composition of the host bird community in the Ammarnäs area from 1999 to 2020, along with the effect of avian malaria infection on host body condition, based on a data set comprising body measurements and infection status for the Plasmodium, Haemoproteus, and Leucocytozoon genera in captured birds from five sample years, and also a

Isocyanate-free polyurethane from cyclic carbonates : Synthesis, application and evaluation

Det pågår ständigt en utveckling för att minska både risker för miljö och hälsa inom den kemiska industrin. Oftast handlar det om att förbättra existerande processer eller att helt enkelt hitta nya vägar till samma produkt och i grunden ligger forskning bakom framgångarna.Polyurethane is a widely used polymer with a lot of different applications due to its versatility and often resilient properties. The polymeris often prepared as a two component system consisting of polyols and isocyanates and can be cured at relatively low temperatures. Even though the formed polymer is hazardless the isocyanate used in the manufacture is dangerous in itself, but even more so is
