A novel pilot-control globe valve, which can be used in vertical pipelines with a lower driving energy consumption, is proposed. A governing equation for valve core motion is obtained through a theoretical analysis of the forces applied on the valve core. A 3D simulation of valve core motion is conducted in Fluent by using User Defined Function (UDF) to involve different spring stiffness, steady s
The main objective of this paper is to study the characteristics of flow-induced noise in high pressure reducing valve (HPRV) and to provide some guidance for noise control. Based on computational fluid dynamics (CFD), numerical method was used to compute flow field. Ffowcs Williams and Hawkings Model was applied to obtain acoustic signals. The unsteady flow field shows that noise sources are loca
The interactions of the anionic bile salt NaGDC with three triblock copolymers based on poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), denoted P65, P123 and F127, were investigated using high-sensitive differential scanning calorimetry (DSC), turbidimetry, dynamic and static light scattering and small angle X-ray scattering (SAXS). P65 and P123 had the same hydrophilic PEO block lengt
The deinstitutionalization of mental health care has changed the responsibilities of involved authoritiesand has led to a continuous need for new treatment forms and interventions. This articledescribes this development in Europe, and in particular how these new conditions have been handledin Sweden over the past 20 years at the level of governmental policy-making. Three major policydocuments from
When developing Community Mental Health Services to support people with psychiatric disabilities, European countries are advocating evidence-based practice (EBP). Individual Placement and Support (IPS) is an evidence-based model designed to support people in acquiring and maintaining competitive employment. Implementation science is a growing research field, with a focus on components that impact
När den statliga revisionen har ett främjande syfte och är problemorienterad kan värdet av revisionen inte utvärderas på traditionellt sätt. Då ligger värdet främst i själva granskningsprocessen och i det kunskapsutbyte som sker under denna. För att undersöka hur Riksrevisionens effektivitetsrevisioner upplevs, har en enkätstudie genomförts. Studien riktade sig till involverade i granskningarna un
Att göra problemen i Riksrevisionens ledning enbart till en fråga om felrekryteringar, såsom Gunnar Axen gör i sin replik, är att göra det lätt för sig. Riksrevisorerna i Sverige har betydligt mer makt än riksrevisorer i övriga nordiska länder. Det finns därför en gräns för hur fritt spelrum de bör ha. Oberoende ska inte föranleda beröringsskräck och det vaccinerar inte mot ansvar. Oberoende ska i
This article presents a corpus-based analysis of stance in a specialized corpus of annual and corporate social responsibility (CSR) reports. It investigates how companies use stance expressions to construct and promote a positive corporate identity in order to gain the trust of the stakeholder groups that these texts target. The results show that companies profile distinct identities in annual and
The purpose of this paper is to describe and produce a more profound understanding of how communication professionals perceive that they realize strategic communication in organizations. Another aim is to deepen the understanding of what consequences the strategic work with communication has for the co-creation of meaning in which the organization is constituted. The paper is based on a qualitativ
Recognition and removal of apoptotic and necrotic cells must be efficient and highly controlled to avoid excessive inflammation and autoimmune responses to self. The complement system, a crucial part of innate immunity, plays an important role in this process. Thus, apoptotic and necrotic cells are recognized by complement initiators such as C1q, mannose binding lectin, ficolins, and properdin. Th
Human bone marrow contains a population of non-hematopoietic stromal stem/progenitor cells (BMSCs), which play a central role for bone marrow stroma and the hematopoietic microenvironment. However, the precise characteristics and potential stem cell properties of defined BMSC populations have not yet been thoroughly investigated. Using standard adherent colony-forming unit fibroblast (CFU-F) assay
Autosomal recessive congenital ichthyosis (ARCI) represents a heterogeneous group of rare disorders of coz1rnification with 3 major subtypes: harlequin ichthyosis (HI), lamellar ichthyosis (LI) and congenital ichthyosiform erythroderma (CIE). A 4th subtype has also been proposed: pleomorphic ichthyosis (PI), characterized by marked skin changes at birth and subsequently mild symptoms. In nationwid
Acetaminophen (APAP) overdoses are of major clinical concern. Growing evidence underlines a pathogenic contribution of sterile postinjury inflammation in APAP-induced acute liver injury (APAP-ALI) and justifies development of anti-inflammatory therapies with therapeutic efficacy beyond the therapeutic window of the only current treatment option, N-acetylcysteine (NAC). The inflammatory mediator, h
This study examines temporal trends in deaths due to fire-related accidents in Sweden from 1952 to 2013 based on statistics in the Cause of Death register held by the Swedish National Board of Health and Welfare. Fatalities coded with underlying cause of death associated with fire-related accidents are included and absolute numbers and age-adjusted mortality rates are calculated and statistically
