Predation on large woody plant seeds; chestnuts, acorns and sloe kernels, was studied in deciduous forests of two size classes: small woodlots (< 1 ha) and large woods (at least 25 ha) in southern Sweden. Seeds used for the study were artificially distributed on the forest ground and seed predation measured as seed removal. Predation rate was similar in both types of woods. However, rodent density
Local signs and symptoms were evaluated in 187 consecutively presenting diabetic patients undergoing amputation for foot ulcers. From admission until final outcome the patients were treated by the same multidisciplinary team both as in- and out-patients. At the time of amputation, the types of lesions were superficial/deep ulcer (n 17), ulcer with deep infection, but without gangrene (n 40), and g
A test of the benchmark QED process e(+) e(-) -->gammagamma(gamma) is reported, using the data collected with the DELPHI detector at LEP 2. The data analysed were recorded at centre-of-mass energies ranging from 161 GeV to 208 GeV and correspond to a total integrated luminosity of 656.4 pb(-1). The Born cross-section for the process e(+) e(-)-->gammagamma(gamma) was determined, confirming the vali
Data supporting the notion that exercise during growth built a stronger skeleton is compelling. Exercise during growth, especially during the pre-pubertal years, increases bone mineral density (BMD) and perhaps also bone size, each independently conferring bone strength. In adulthood, exercise at best halts bone loss or increases BMD by a few percentage points, an increase of questionable biologic
We show that it is possible to understand and interpret the complex and rich C-H stretch region in the vibrational spectrum of ethoxy adsorbed on W(110) in terms of fundamental C-H stretch modes in Fermi resonance with C-H deformation overtones and combinations. The mode assignment is based on calculated C-13 isotopic shifts for an ethoxy-Cu-5 cluster. The coupling constants have been derived from
A prominent increase in atmospheric CO, at the Paleocene-Eocene boundary, ca. 55 Ma, led to the warmest Earth of the Cenozoic for similar to 100 k.y. High-resolution studies of continental flood-plain sediment records across this boundary can provide crucial information on how the hydrological cycle responds to rapidly changing CO2. Here we show from continental records across the Paleocene-Eocene
Den offentliga statistiken inom äldreomsorgsområdet är för närvarande begränsad till mängdstatistik (Statistik - socialtjänst 2000:5, Socialstyrelsen 2000 och Hälso- och sjukvårdsstatistisk årsbok 1999, Socialstyrelsen 2000). Från denna statistik erhålles uppgifter om antalet äldre som får vård och hjälp fördelade på ålder, kön och vårdinsats samt vårdkostnader. För att få insikt i äldreomsorgssys
In a previous study, we identified suggestive linkage between type 2 diabetes and a locus on chromosome 9p13-q21. This region contains the gene annexin I (ANXA1), encoding a protein suggested to be involved in both insulin secretion and insulin action. In this study, we sequenced the exon/intron boundaries of the human ANXA1 gene and performed mutation screening in 41 individuals from the initial
The aim was to gain knowledge of young people's physical status and physical activity, and to further the understanding of the role of school physical education in a salutogenic public health perspective. Two studies were performed in southern Sweden. Study 1 was performed in 1996 among 301 adolescents aged 16-19 in upper secondary school. It comprised three parts: a questionnaire, seven physical
The Kyoto Protocol opens new possibilities for using the biosphere as a carbon sink. Using agro-ecosystems as carbon sinks may be the most appropriate practice from both environmental and socioeconomic points of view. Degraded agro-ecosystems in Africa might benefit significantly from the improved land management that would be part of a carbon sequestration program. There are vast areas of these a
Clinically, hemodilution to a hematocrit of 9% has been studied, but the effects of hypovolemia during this degree of hemodilution have not been elucidated. We studied the response to blood loss during extreme hemodilution and evaluated indicators of hypovolemia. Systemic and myocardial hemodynamics, oxygen transport, and blood lactate concentrations were measured in 12 anesthetized pigs exposed t
In this study, cancer patients' characteristics associated with death in nursing homes were explored. The study sample included 395 cancer patients who had participated in a trial of palliative care, 260 ( 66%) patients died in hospital, 80 (20%) at home and 55 (14%) in nursing homes. Health-related quality of life was prospectively recorded using the EORTC QLQ-C30 questionnaire. Death in nursing
