The overall structure of the biogenic amine subclass of the G-protein-coupled receptors, and of their ligand binding sites, is discussed with the aim of highlighting the major structural features of these receptors that are responsible for ligand recognition. A comparison is made between biogenic amine receptors, peptide receptors of the rhodopsin class, and the secretin receptors which all have p
The preganglionic nerves of the rat urinary bladder were cut. The decentralized bladders gained markedly in weight. Both one and four weeks post-operatively, transmural nerve stimulation evoked contractile responses of the muscle strips of the decentralized bladders, that were of the same magnitude as those of the control bladders. However, four weeks post-operatively, the atropine resistant fract
Steroid injections are often employed as an alternative treatment for radicular pain in patients with degenerative spinal disorders. Prospective randomised studies of the lumbar spine reveal contradictory results and non-randomised and most often retrospective studies of the cervical spine indicate pain reduction from steroid injections. No prospective randomised study on transforaminal steroid in
We report on preliminary results from time-resolved optical spectroscopy of the He-rich variable white dwarf GD 358.
A combustion system was developed to burn a low value gas in the VT4400 IGT engine demonstrator. The combustor was designed in an engine configuration consisting of a single LCV combustor operating in combination with six LP combustors.
Thread-Level Speculation can be used to take advantage of multicore architectures for web applications. We have implemented Thread-Level Speculation in the state-of-the-art JavaScript engine V8 instead of using an interpreted JavaScript engine. We evaluate the implementation with the Chromium web browser on 15 popular web applications for 2, 4, and 8 cores. The results show that it is beneficial t
Denna avhandling handlar om teoretisk partikelfysik. Partikelfysik handlar om elementarpartiklar och hur dessa växelverkar med varandra, dvs vilka krafter som verkar mellan dem. Detta är hur materien ser ut på den minsta skala vi har kunnat studera experimentellt. Den teori som beskriver de starka, svaga och elektromagnetiska krafterna och de materiepartiklar som vi känner till, kvarkar och leptonThis thesis includes two topics.The first three papers is the major part of this thesis, which is about higher order calculations in the effective field theories of three QCD-like theories. These three QCD-like theories are distinguished by having quarks in a complex, real or pseudo-real representation of gauge group. We wrote their effective field theories in a very similar way so that the calcul
The inverse scattering problem on the half-axis for long range potentials is studied. It is shown that the solution of the inverse problem contains arbitrary real parameters iven if no bound states are present. Connections with the inverse problem on the whole axis are discussed.
This report was initiated and conducted as input to the discussions based on the “Vision 2015” document for the Nordic Swan that explicitly states a wish to find ways to make use of ecolabelling in the green public procurement (GPP) setting. In 2014, the Directive (2004/18/EG) on public procurement was revised and replaced by Directive (2014/24/EU). Some of the restrictions in using ecolabelling i
We investigate a model for buffer management of multi-class traffic into a finite shared buffer. A hierarchy of increasingly stronger linear programming relaxations for this model is proposed. The number of hierarchies equals the number of job classes. Each relaxation in the hierarchy is constructed by projecting the original achievable performance region into a polytope with fewer variables and f
How do small states approach their security problems? What types of strategic instruments exist for small states, and when and why are certain strategies chosen rather than others? The security of `weak' states is problematic, demanding trade-offs in the decisions made. Using 19th century Swedish security policy as an example, it is argued here that small states, in their pursuit of security and a
This thesis set out to continue the development of a short-wave infrared (SWIR) optical parametric amplifier (OPA). The system is based on a Yb-ber chirped pulse amplification (CPA) laser delivering 400 fs long pulses, centered around 1030 nm, at 200 kHz repetition rate and 40 W average power. The thesis focuses on pulse characterization, through use of frequency-resolved optical gating (FROG), of
The combined global emergence of a sustainable development discourse and Swedish policies requiring municipalities to rapidly build new housing have led Lund to develop Brunnshög. This pioneering megaproject balances urban expansion with high sustainability ambitions. Through the lens of urban political ecology, this thesis aims at analysing Brunnshög’s dominant sustainability narrative as told by
Väpnade konflikter är komplexa och mångfacetterade – män och kvinnors roller och nivå av inblandning varier avsevärt. Med detta i åtanke är det nödvändigt för internationell rätt och dess utövare att erbjuda ett reellt skydd, där ansvarsutkrävande och upprättelse erbjuds på lika villkor för alla oavsett kön. Risken är annars att vissa grupper osynliggörs. Sammanfattningsvis krävs det en nyanserad
