Nerve fibres play an important role in the regulation of gastric emptying. The aims of this study were to clarify the distribution, projections and origin of neuronal type nitric oxide synthase (NOS)-, tyrosine hydroxylase (TH)-, vesicular acetylcholine transporter (VAchT)- and peptide-containing nerve fibres of the rat pyloric sphincter. Extrinsic and local denervations of the sphincter were perf
Background: The aim of this study was to explore the feasibility of using a technique based on artificial neural networks for quality assurance of image reporting. The networks were used to identify potentially suboptimal or erroneous interpretations of myocardial perfusion scintigrams (MPS). Methods: Reversible perfusion defects (ischaemia) in each of five myocardial regions, as interpreted by on
This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr
Stellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. In particular, hyperfine structure (hfs) data in the near-infrared region is lacking
Title: Mapping, development and optimization of internal logistics in a multi- stage production facility Authors: Nils Jönsson and Björn Hofbard Supervisors: Eva Berg, Department of Industrial Management and Logistics. Conny Andersson, Sandvik Background: In highly dynamic and competitive environments, supply chain management and logistics can create important advantages against competitors. Since
The noise, vibration and harshness (NVH) and body dynamic performance of automotive vehicles is highly dependent of the components included in the body structure and compartment, since they add mass, stiffness and damping to the overall structure. Today, the noise levels in the compartment are predicted using complex and detailed computational models during both early and late stages of the vehicl
Electrical power distribution is currently seeing both challenges and opportunities. On one hand, the digitisation of measurement data and modern measurement devices enable deeper analysis and planning of the grid. On the other hand, the expansion of privately owned photovoltaic systems and the customers' desire to produce their own electricity is an inevitable challenge that distribution comp
Sverige är en rättsstat som bygger på många olika principer för att kunna för-säkra ett fungerade rättsväsende. En viktig sådan är principen om domens orubblighet. De domar som en domstol meddelar ska stå fast när dessa vunnit laga kraft, vilket kallas för en doms negativa rättskraft. Vidare har de mänsk-liga rättigheterna som inkorporerats i svensk lagstiftning genom EKMR en stor plats vid lagstiSweden is a state governed by the rule of law, and is based on many different principles in order to ensure a functioning justice system. An important prin-ciple is that the rulings from the courts should be adamant, also known as the principle of firmness. The ruling of the court shall stand when it has gained legal force and this is also known as the negative legal force of a judgment. The human
The aim of the study at had was to explore the potential of Natural Capital Accounting (NCA) to integrate environment into business decision-making. In order to fulfill the aim, the research was split into three main parts. First, the existing views on what constitutes NCA were reviewed through a literature analysis of grey literature, and the working definition established. The study found that t
With the climate change and urbanization process, the frequency of the urban flooding’s occurrence has increased in the recent years. It brings great economic losses to the cities, especially to the basements of individual properties. Low Impact Development (LID), which currently advocated by more city planners for managing stormwater, is considered as a more sustainable way to mitigate urban floo
Att vittna är en lagstadgad skyldighet i Sverige. Om man vägrar att inställa sig som vittne trots att man är kallad riskerar man att tvångsmedel riktas mot en. Under senare tid har möjligheten till anonyma vittnesmål diskuterats på en rad olika håll i samhället, då man allt oftare ser en ovilja att vittna på grund av rädsla att drabbas av repressalier. Enligt en allmän uppfattning är det inte tillTo testify is a statutory duty in Sweden. If one refuses to testify, even though one are called by the court, one risks that compulsions will be directed towards one. Recently, the possibility of anonymous testimony has been discussed in the Swedish society, as the reluctance to testify has increased due to the fear of reprisals. But according to the general view in Sweden, it is not allowed to wi
Issue of Study: The master thesis was conducted at Tetra Pak, a large multinational manufacturing firm within the business to business setting. They have a history of renowned innovations and have with their innovations, become the market leader within their industry. In recent history, they have tried using open innovation for certain projects in an ad hoc manner, but do not have any clear vision
During the spring semester 2018, an investigation about supplementary cleaning of the waste water at Dow Chemical site in Landskrona was done. Different water-based binders from acrylic monomers are produced by Dow and large amounts of water is used for such processes. The wastewater, that is treated currently by ultrafiltration (UF), contains different chemical residues such as surfactants, resid
Hate speech on social media hardly remains unnoticed. Contents involving hateful messages vary from “kill a Jew day” to “kick a ginger day” and could target anyone irrespective of their status, identity, location and so forth. Even when hate speech is not materialized into a hate-motivated crime, the damage is done – victims are being labeled, marginalised and exposed to negative stereotyping. The
Highly glazed spaces are continuously increasing in popularity due to architectural attractiveness. However, increased use of glass often jeopardizes thermal comfort in several ways and problem of overheating is one of them. A way to face this problem is to appropriately use solar control mechanisms. However, a proper selection of solar control mechanisms from an early design stage is a complex ta
The undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt
Under det senaste decenniet har rättsstatens ställning som ett värde av grundläggande vikt för EU-rätten ifrågasatts genom den politiska utvecklingen i vissa medlemsstater. Särskilt i Polen och Ungern går det att se hur centraladelar av statsmakten har nedmonterats. År 2021 införde EU en villkorlighetsmekanism, som ger EU:s institutioner befogenhet att hålla inne budgetåtaganden till medlemsländer
I svensk rätt tillämpas asperationsprincipen vid straffvärdebedömning av flerfaldig brottslighet. Vid flerfaldig brottslighet ska ett gemensamt straffvärde bestämmas och domstolen utgår från det allvarligaste brottets straffvärde och de övriga gärningarnas straffvärden reduceras i en fallande skala. Detta system har mött kritik i form av att påföljderna vid flerfaldig brottslighet blir för milda iIn Swedish law, the principle of asperation is applied when estimating the penal value for multiple offences. In the case of multiple offences, a common penal value is determined and the court starts from the most serious offence, with the penal value of the other offences being reduced on a descending scale. This system has been criticized for making penalties for multiple offences too lenient in
Problem Statement: Company Pie is planning for a new centralised distribution centre, as part of a reorganisation of their distribution network. This entails consolidating volumes from several existing facilities, and another company named Company Rho, when setting up a distribution centre configuration. Company Pie wants a second set of eyes to create a configuration, including operations, and de
Cardiac magnetic resonance (CMR) images are used to investigate the heart for medical and research purposes. By injecting a contrast substance into the patient, myocardial infarctions (heart attacks) can be visualized in CMR image sets consisting of a number of image slices at different levels of the heart. Analysis of these images can detect an infarction, delineate it and estimate its size. This
