Oxytocin (OT) and vasopressin (VP) are neurohypophyseal hormones with potent stimulatory actions on the uterus. In order to determine whether these hormones may have a paracrine action on the uterus, OT and VP gene expression was studied in myometrium from pregnant rats at gestational ages of 14 and 20 days, and from ovariectomized animals treated with oestradiol and progesterone. OT and VP mRNA c

Large-scale protein conformational motions on nanosecond – microsecond time scales are important for many biological processes, but remain largely unexplored because of methodological limitations. NMR relaxation methods can access these time scales if protein tumbling is prevented, but the isotropy required for high-resolution solution NMR is then lost. However, if the immobilized protein molecule

The key step in the reaction mechanism of multicopper oxidases (MCOs)-the cleavage of the O-O bond in O-2-has been investigated using combined quantum mechanical and molecular mechanical (QM/MM) methods. This process represents a reaction pathway from the peroxy intermediate after it accepts one electron from the nearby type-1 Cu site to the experimentally-observed native intermediate, which is th

Substructure coupling and model order reduction using Component Mode Synthesis (CMS) have, over recent years, gained considerable attention in the vibroacoustic analysis of complex structures. In the CMS methodology, the interior dynamics of each subcomponent in a substructured system are represented by a truncated set of normal modes within the lower frequency range, while all physical degrees of

In most non-fullerene organic solar cells comprising bulk-heterojunction active layers, the inter-domain connectivity of small-molecule acceptors is generally inferior to those of polymeric donors due to their intrinsic short-range ordering. This issue is even exacerbated by the physiochemical mismatch between acceptor-phases and metal-oxide electron transport layers in most inverted n-i-p devices

Background and objectiveOrganised prostate cancer (PCa) testing (OPT) was introduced in Sweden to gain knowledge in preparation for a potential national PCa screening programme. This study aims to explore men’s opinions regarding the OPT invitation letters and the attitudes influencing their decision to participate in or decline OPT.MethodsWe conducted semi-structured telephone interviews with 30

Liquid-crystalline cubic-phase nanoparticles (CPNPs) (known as Cubosome particles), based on the lipid glycerol monooleate and stabilized by the nonionic block copolymer Pluronic F-127, interact with supported model membranes consisting of dioleoylphosphatidylcholine (DOPC) in a complex and dynamic fashion. Neutron reflectivity measurements on the interaction of CPNPs with bilayers of different co

The Prototype Repository, at the Aspo HRL (Hard Rock Laboratory), is a demonstration project for the deposition of spent nuclear fuel, and provides a full-scale reference for testing predictive models relating to a spent nuclear fuel repository, both its individual components as well as the complete system. The final layout involves six deposition holes, four in an inner section and two in an oute

The purpose of this master’s thesis is to gain a better understanding of how public librarians describe their interactions with Google Search, as well as their opinions on both the company and the search engine Google. The main focus of interest is the information seeking process that public librarians perform in response to questions from library users, and the alternatives and choices, such as d

Syftet med examensarbetet är att ta reda på hur delning av lokaler fungerar idag och undersöka potential samt de utmaningar som föreligger för att kunna etablera delningsekonomi inom fastighetsbranschen. Studien har främst fokuserat på det befintliga fastighetsbeståndet i Sverige. Syftet uppnås genom att besvara följande två frågor: 1. Hur används delningsekonomi inom fastighetsbranschen idag? 2.The aim of this thesis was to research the current status of shared space use. Furthermore, this thesis also aimed to investigate the potential and challenges related to sharing economy in the real estate sector. The thesis focused mainly on existing buildings in Sweden. The aim was to answer the following two research questions: 1. How is sharing economy used in the real estate industry? 2. What

Singapore has remarkably transformed from a small and poor Southeast Asian island into an affluent global city-state today. However, in contemporary times, the distribution of the gains from the nation’s progress and prosperity has been increasingly unequal. An understanding of the extent of income inequality is imperative to reassess the current policies and resource allocation decisions. The aim

In this master’s thesis, the development of a new belt tensioning solution, for use in ASSA ABLOY's sliding doors is treated. As a starting point for the work, ASSA ABLOY’s current belt tension solution has been used as a reference. On this reference, an extensive problem analysis have been carried out, including interviews, field studies and laboratory tests in order to understand what is req

Introduction Health technology assessment (HTA) is an area that remains less implemented in low- and lower middle-income countries. The aim of the study is to understand the perceptions of stakeholders in Uganda toward HTA and its role in decision making, in order to inform its potential implementation in the country. Methods The study takes a cross-sectional mixed methods approach, utilizing an a

The conceptual shift in the expectations of the wireless users from voice towards multimedia, from availability towards acceptable quality, and from stand-alone towards group-oriented computing has a significant impact on today's networks in terms of the need for mobility, quality of service (QoS) and multicasting. Ad hoc networks, being independent of any fixed infrastructure, can provide mobile

Popular Abstract in English This thesis is concerned with the efficient generation of ultra-short light pulses, far beyond the visible spectral range. Such light pulses can reach durations below 100 attoseconds, where one attosecond is one billionth of a billionth of a second. Why do we want to generate such extreme light pulses? Our knowledge of basic processes in physics and chemistry is to a

Modern working life is characterized by change and competiveness. It is also characterized by a drift away from low-skilled work to more complex jobs and increased social interaction. This means that the human resources employees and their skills, competencies, engagement and motivation are the greatest asset of many organizations. This has implications for how an organization can be healthy, i.e.

The oxidation of biogenic volatile organic compounds (BVOCs) gives a range of products, from semi-volatile to extremely low-volatility compounds. To treat the interaction of these secondary organic vapours with the particle phase, global aerosol microphysics models generally use either a thermodynamic partitioning approach (assuming instant equilibrium between semi-volatile oxidation products and

We show that the 2.4σ signal of the leptonic flavor violating (LFV) Higgs boson decay h→μτ, as observed by the CMS Collaboration recently, can be explained by a certain class of two-Higgs doublet models that allow controllable flavor-changing neutral current with a minimal number of free parameters. We postulate that (i) the alignment limit is maintained, which means the lightest neutral scalar (h
