There has been little development regarding analysis of polonium (Po) in environmental samples since the 1960ies. This is due to the straightforward spontaneous deposition of this element on silver (Ag), nickel (Ni) or copper (Cu) without any radiochemical separation. For many years, no radiochemical yield determinant was used and it was generally supposed that the yield was 100% after two deposit
Activation products which contribute significantly to the exposure of the staff operating the accelerator were found in the accelerator head in the transparent holder for the lead blocks and in the 60 degrees wedge filter made of lead. A proper choice of material in these parts of the accelerator could easily reduce this exposure without excessive changes in the construction. The absorbed dose-rat
This work provides the first morphological analysis (both at gross and fine level) of the antennal structures in the genusElater (Coleoptera, Elateridae). The typology, number and distribution patterns of the antennal sensilla in the rare saproxylicElater ferrugineus (both male and female) were studied using scanning electron microscopy (SEM). The serrate antennae ofE. ferrugineus consisted of a s
AIMS: Vitamin B12 deficiency could be associated with cardiovascular autonomic neuropathy (CAN) in diabetes patients. We aim to investigate the association between serum levels of vitamin B12 and CAN in type 2 diabetes patients.METHODS: 469 ambulatory type 2 diabetes patients (mean diabetes duration 10.0years (IQR 5.0;17.0), mean age 59.0years (SD 11.6), 63% men, mean B12 289.0pmol/l (IQR 217;390)
The Fontan procedure has improved survival in children with functionally univentricular hearts. With time, however, complications such as reduced exercise capacity are seen more frequently. Exercise intolerance is multifactorial, but pulmonary vascular resistance probably plays a crucial role. Elevated pulmonary vascular resistance has been associated with raised levels of endothelin-1, which are
Quantum fluctuation of the energy is studied for an ultracold gas of interacting fermions trapped in a three-dimensional potential. Periodic-orbit theory is explored, and energy fluctuations are studied versus the particle number for generic regular and chaotic systems, as well as for a system defined by a harmonic confinement potential. Temperature effects on the energy fluctuations are investiga
The cytokine IL-7 and its receptor are essential for normal B and T lymphopoiesis. We have analyzed the role of this receptor in B cell development throughout ontogeny in IL-7 receptor alpha-deficient mice. We demonstrate that the IL-7 receptor becomes progressively more important with age. B lymphopoiesis takes place, albeit at reduced levels, in fetal liver and bone marrow of young mice, but is
As most manufacturing companies Alfa Laval needs to find new ways to differentiate by shifting the current product focus towards a more service oriented approach. Many manufacturing companies find it difficult to increase service revenues successfully. High investments in extending the service business do not result in the expected higher returns, providing a service paradox. To overcome the parad
Värdebaserad styrning utgörs av en samling principer, vilka ska ge en vägledning för att mäta prestationer, allokera resurser samt sätta finansiella mål. Detta görs utifrån den grundläggande förutsättningen att aktieägarvärde skapas när avkastningen överstiger investerarens kapitalkostnad. För att lyckas med implementeringen och den fortsatta tillämpningen av VBM anser vi att företaget bör följa n
Syftet med uppsatsen är att beskriva och analysera välkända strategimodellers applikationsförmåga för de specifika förutsättningar som tjänsteföretag inom storhushåll verkar inom. Metoden som vi valt är kvalitativ och materialet som används tar sin utgångspunkt i sekundärdata i form av offentliga och institutionella källor från kända strategiforskare och branschspecialister. Uppsatsen utgår teorim
Denna uppsats undersöker följande frågeställningar: Spelar personalens agerande en avgörande roll för huruvida kunden återkommer till spa-salongen? Hur bör företaget förhålla sig till endera utfall? Vi har valt att undersöka spa-industrin då vi finner lojalitetsproblematiken i denna kontext intressant då tjänstemötet omfattas av en hög interaktion och intimitet spa-personal och kund emellan. Uppsa
OBJECTIVE: To investigate to what extent individuals participated in guideline-based first-line treatments before being assigned to a wait list for knee replacement for osteoarthritis (OA), and to what extent they were recommended such treatments once on the list. Factors associated with participation in first-line management were also investigated.DESIGN: All patients on the waiting list ≥ three
In Sweden it is permitted to aim Internet commercials at children of all ages. However, when it comes to television, mail and e-mail there are certain bans on child commercials. The difference can be difficult to comprehend since Internet commercials frequently are embedded in non-commercial material and since the children now grow up in a digital world. The question formulation of this essay is i
