We explore how the width of the three-pulse photon echo signal at long population times can be used to determine the strength of the system-bath interaction. Using simulation with finite pulses we show that a simple relation exist between the width of the echo signal, the coupling strength, and the pulse autocorrelation. The derived model is applied to Rhodamine 6G in alcoholic solution, a paradig
It is well known that the origin of one type of spurious solutions in multiband k(.)p theory is the failure to restrict the Fourier coefficients of the envelope functions to the first Brillouin zone. Often, the set of differential equations obtained is supplemented with interfacial boundary conditions derived by integrating the differential equations across the interface; however, this leads to a
It is generally accepted that early detection of breast cancer has great impact on patient survival, emphasizing the importance of early diagnosis. In a widely recognized model of breast cancer development, tumor cells progress through chronological and well defined stages. However, the molecular basis of disease progression in breast cancer remains poorly understood. High-throughput molecular pro
A mesocosm experiment indicated that water transparency influenced antipredator behaviour in young-of-the-year perch Perca fluviatilis, which partly contradicts another study by showing that high transparency decreases rather than increases perch antipredatory use of vegetated habitats when predators are also free to choose habitat. The present study emphasizes the importance of simultaneously con
Purpose. To describe, by use of a phenomenological approach, how transfemoral amputees experience their first meeting and subsequent interaction with hospital staff in the acute phase, in the long term and suggestions for future care-giving. Method. Eleven transfemoral amputees, median age 33.5 years, were interviewed. The amputations, performed in median 7.5 years before the interview, were cause
This article focuses upon 28 Swedish foster parents and their experience of working in a manual-based treatment program - Multidimensional Treatment Foster Care (MTFC) - focusing on treating troubled youth. Using interviews and questionnaires, the study addresses how foster parents perceive the components and core terms specific to MTFC. Both quantitative and qualitative analyses were conducted. I
Radiative lifetimes of 16 odd levels belonging to the 4d(2)5p configuration of Zr II have been measured using a time-resolved laser-induced fluorescence technique with a single-step excitation process either from the ground state or from metastable levels belonging to the 4d(2)5s and 4d(3) configurations. For 12 levels, there were no previous results available. The new experimental results and the
Objectives The aim of the study was to illuminate the lived experience of being given a cancer diagnosis in old age. Background Little research has been done on the experience of elderly people developing cancer and the impact of the illness on their lives. Such knowledge is needed to support elderly people in dealing with issues arising after cancer is diagnosed. Design A descriptive phenomeno
Silurian palaeobiogeography of the Ramphoprionidae (Annelida; Polychaeta) is outlined. Members of the family are reported from northern Europe (Estonia, Sweden and England), the Russian Arctic (Severnaya Zemlya), and the Canadian Arctic (Baillie-Hamilton Island), These areas were located fairly close to the palacoequator during the Silurian and a faunal exchange is indicated by the broad, intercon
We demonstrate a possibility of multistep electron transfer in a supramolecular complex adsorbed on the surface of nanocrystalline TiO2. The complex mimics the function of the tyrosineZ and chlorophyll unit P680 in natural photosystem II (PSII). A ruthenium(II) tris(bipyridyl) complex covalently linked to a L-tyrosine ethyl ester through an amide bond was attached to the surface of nanocrystalline
We have previously identified a locus on mouse chromosome 15 (eae2) that regulates susceptibility to experimental autoimmune encephalomyelitis in a cross between the susceptible strain B10.RIII and the resistant strain RIIIS/J. In an effort to verify the protective effect from having two RIIIS/J alleles at eae2, the resistant locus was bred into the susceptible strain in homozygous form. However,
A number of polyamine analogs are currently used in various clinical trials as cancer treatment and it is important to investigate their effects not only on cancer cells but also on normal cells. Treatment with polyamine analogs depletes cells of polyamines and inhibits cell proliferation, but the analogs cannot take over the normal function of the natural polyamines in the cell. In this study, th
Objectives: Underweight, overweight, and obese women aged 18–34 years were compared with normal weight women of the corresponding age according to socioeconomic, psychosocial, health behaviour, self reported global and psychological health, and locus of control characteristics. Methods: The 2000 public health survey in Scania is a cross-sectional study. A total 13 715 persons aged 18–80 years, of
The aim of the study was to investigate the relationship between coping and health problems in the context of gender and level in the organization. Questionnaire data were collected from 279 women and men (100 managers and 179 non-managers) at a sales department in a Swedish telecom company in which men and women worked at similar tasks. It was hypothesized that, if gender and level in the organiz
A prevalence of hepatitis C virus (HCV) antibodies of 12% was found in 276 patients from 11 dialysis units. Between zero and 22% of the patients in the different units were anti-HCV positive. The epidemiology of HCV was studied in two units during a 2 year period by antibody assays and the polymerase chain reaction and correlated with clinical manifestations. Two types of epidemiologic patterns we
The prognostic impact of t(12;21)(p13;q22) [ETV6/RUNX1 fusion] in paediatric acute lymphoblastic leukaemia (ALL) has been extensively debated, particularly with regard to the frequency of late relapses and appropriate treatment regimens. We have retrospectively collected 679 ALLs with known ETV6/RUNX1 status, as ascertained by fluorescence in situ hybridization or reverse-transcription polymerase
AIM: The aim of this study was to describe eating difficulties and especially swallowing in patients with dysphagia, types of nursing intervention, and the development of complications over 3 months. The aim was also to explore common characteristics of eating difficulties that influenced the ability to finish meals. METHODS: Twenty-four consecutive patients admitted because of stroke and dysphagi
This study was designed to test the hypothesis that younger patients treated for osteoarthritis and similar conditions using total knee arthroplasty and unicompartmental knee arthroplasty have a lower implant survival rate when compared with older patients. Previous studies have been done on a small number of patients and only included the younger patients. In many cases patients treated for rheum
