Normal ageing in men is associated with a physiological decline in testosterone levels, but adverse environmental or psychosocial factors may also impair testosterone secretion and cause secondary biological changes. In a number of observational or experimental studies in both animals and man, it has been possible to study the influences on gonadal function of stressful life situations. To underst
This paper presents a numerical investigation of heat transfer from impinging swirling jets. Various turbulence models are used. Comparison with experimental data is provided. Generally the V2F model was found to perform better than other models but for small nozzle to plate distances it was hard to maintain good accuracy. The difference in performance, in terms of the Nusselt number distribution
An important component of the aircraft generated noise, especially ahead of it, is the fan noise created by the high velocity variation near the blades and the interaction of the rotating fan with the fluid. In order to predict the sound, the method used involves the acoustical analogy developed by Ffowcs Williams and Hawkings. Computation of the flow field is performed in the incompressible LES f
Designers’ work sometimes originates from a simplified view of human demands and needs, which may result in furniture that does not fulfill the user requirements. If we consider old people as one group with fairly similar needs and demands rather than have realistic images of old people as a heterogeneous group there is a tendency that it will result in misguided efforts to design for wellbeing. T
In a recently conducted interview study, some survivors of traffic victims rate their home as the most important place for remembrance, compared to both the accident site and the burial plot. The reason for this evaluation appears to be the place’s ability to bring about a positive presence of the deceased. Supported by photographs and personal objects, the home serves as a constant reminder, and
Kapitlet ger en sammanfattande bild av etableringsvillkoren för ungdomar (16-19 år) och unga vuxna (20-24 år) samt deras utanförskap i Sverige från början av 1990-talet fram till idag. Kapitlet omfattar tre avsnitt. I det första avsnittet ges en bakgrundsteckning om ungdomars etablering på den svenska arbetsmarknaden. Översikten sammanfattar forskningsresultat om arbetsmarknad, utbildning och förs
BACKGROUND: Androgen insensitivity is caused by mutations in the androgen receptor gene, and is a common etiological factor to ambiguous genitalia in the newborn. This article discusses the role of androgens in sex differentiation, the structure and function of the androgen receptor, the genetic background to androgen insensitivity as well as clinical aspects. MATERIAL AND METHODS: The article is
Dietary carbohydrates have been implicated in relation to prostate cancer.
This thesis investigates the dynamics between firms’ shifting motives for engaging in foreign direct investments (FDIs) and the experiential knowledge acquired from increased experience and establishment in foreign markets. An embedded case study was performed on the multinational company Duni Group, drawing upon insights from semi-structured interviews with representatives from the case company.
Bone Scan Index (BSI) is a quantitative measurement of tumour burden in the skeleton calculated from bone scan images. When analysed at the time of diagnosis, it has been shown to provide prognostic information on survival in men with metastatic prostate cancer (PCa). In this study, we evaluated the prognostic value of BSI during androgen deprivation therapy (ADT).
Blood vessels and adjacent cells form perivascular stem cell niches in adult tissues. In this perivascular niche, a stem cell with mesenchymal characteristics was recently identified in some adult somatic tissues. These cells are pericytes that line the microvasculature, express mesenchymal markers and differentiate into mesodermal lineages but might even have the capacity to generate tissue-speci
The aim of this study was to use multi-radionuclide autoradiography to compare the different distributions of three radiolabelled tracers in an atherosclerotic mouse model. This method, along with immunohistochemistry, was applied to investigate the intra-aortic distribution of 2-deoxy-2-[(18)F]fluoro-D-glucose ((18)F-FDG), (131)I/(125)I labeled anti-oxidized Low Density Lipoprotein (oxLDL), and n
A flattening filter free x-ray beam mode was added to an Elekta linear accelerator by placing a flat copper plate in the filter carousel and recalibrating the electron steering servo, gun servo and dosimetry system. Machine configurations were saved onto a separate hard disk in order to remain separate from the clinical configuration. Profile measurements with a Schuster BMS diode array show that
This paper will focus on a comparative analysis of the gendered social construction of parenting (mothering and fathering); in relation to possible relationship burdens faced by parents, in the process of care giving and administration of therapeutic mechanisms, to children diagnosed with Autism Spectrum Disorder (ASD). The gendered social construction of parenting and respective burdens will be a
