A highly scattering porous ceramic sample is employed as a miniature random-scattering multipass gas cell for monitoring of oxygen content in opaque media, that is, wood materials in the present work. Gas in scattering media absorption spectroscopy is used by employing a 760 nm near-infrared laser diode to probe the absorption of molecular oxygen enclosed in the pores of the ceramic material worki
Enzymes were deposited on different porous support materials and these preparations were used to catalyze reactions in organic media. Reactions were carried out at specific water activities, achieved by equilibrating both the enzyme preparation and the substrate solution at the desired water activity before mixing them and thereby starting the reactions. The reaction rates obtained at the same wat
Refugees have been arriving in Europe from North Africa for years, but it wasn't until 2015 that the issue gained widespread public attention. That year saw a significant increase in the number of refugees and migrants, with 911,000 individuals reaching European shores via perilous routes across the Mediterranean Sea, particularly between Italy and Libya, and between Turkey and Greece. This th
This thesis, which is based on four original papers, deals with human dendritic cells (DCs) in immunity and allergy. DCs play a key role in the regulation of immune responses by acting as the sentinels of the immune system, specialized in the uptake of a diverse range of antigens. These cells migrate to local lymph nodes and become highly efficient in inducing T cell proliferation, thus inducing a
The Drosophila melanogaster deoxyribonucleoside kinase (Dm-dNK) double mutant N45D/N64D was identified during a previous directed evolution study. This mutant enzyme had a decreased activity towards the natural substrates and decreased feedback inhibition with dTTP, whereas the activity with 3'-modified nucleoside analogs like 3'-azidothymidine (AZT) was nearly unchanged. Here, we identify the mut
Competitive breath-hold divers try to achieve maximum times, depths, or distances underwater, thereby risking hypoxic syncope. In the present study, the cardiorespiratory responses to dynamic apnea (simultaneously initiated apneas and dynamic leg exercise) were investigated in 10 breath-hold divers. The divers performed 60 s dynamic apneas with the face in air (A) or face immersed in cold water (A
The aim of this qualitative study was to explore older persons' (n = 28, 75-96 years of age) experience of becoming in need of public home help, their experience of participation and of having influence on the needs assessment procedure and the decisions made about public home help. A content analysis revealed a broad overarching category, labelled: experiencing discontinuity in life as a whole -
We investigated the wear characteristics and clinical performance of four different total hip joint articulations in 114 patients. Wear and migration was measured by roentgenstereophotogrammetric analysis at five years or at the last follow-up. The mean annual wear was 0.11 mm for a stainless steel/Enduron articulation, 0.34 mm for stainless steel/Hylamer cup, 0.17 mm for zirconium oxide ceramic/E
A search for resonant WZ production in the l nu l'l' (l, l' = e, mu) decay channel using 20.3 fb(-1) of root s = 8 TeV pp collision data collected by the ATLAS experiment at LHC is presented. No significant deviation from the Standard Model prediction is observed and upper limits on the production cross sections of WZ resonances from an extended gauge model W' and from a simplified model of heavy
Objective: Lack of sensory feedback is a drawback in today's hand prostheses. We present here a non-invasive simple sensory feedback system, which provides the user of a prosthetic hand with sensory feedback on the arm stump. It is mediated by air in a closed loop system connecting silicone pads on the prosthetic hand with pads on the amputation stump. The silicone pads in a "tactile display" on
OBJECTIVE-To report the incidence of sight-threatening vascular lesions in type 2 diabetic subjects without retinopathy after adopting a 3-year interval screening program. RESEARCH DESIGN AND METHODS-In all, 1,691 type 2 diabetic subjects with no detectable retinopathy in two 50 degrees red-free fundus photographs were scheduled for follow-up with photography 3 years later. Age at diabetes diagnos
Reality TV is popular entertainment. And yet a common way to start a conversation about it is ‘I wouldn’t want anyone to know this but…’ Why do people love and love to hate reality TV? This book explores reality TV in all its forms - from competitive talent shows to reality soaps - examining a range of programmes from the mundane to those that revel in a spectacle of excess. Annette Hill’s resear

Engineering design problems are most frequently charac-terized by constraints that make them hard to solve and time-consuming. When evolutionary algorithms are used to solve these problems, constraints are often handled with the generic weighted sum method or with techniques specific to the prob-lem at hand. Most commonly, all constraints are evaluated at each generation, and it is also necessary
