Questions Can the model performance of the landscape reconstruction algorithm (LRA) for small forest hollows be validated through comparison to inventory-based vegetation reconstructions from the last 150yrs? Does the application of LRA and the comparison to historical data enhance interpretation of the pollen record? Location Denmark. The Gribskov-Ostrup small forest hollow (56 degrees N, 12 degr
Regional climate models (RCMs) primarily represent physical components of the climate system, omitting vegetation dynamics, ecosystem biogeochemistry and their associated feedbacks. To account for such feedbacks, we implemented a novel plant individual-based vegetation dynamics-ecosystem biogeochemistry scheme within the RCA3 RCM. Variations in leaf area index (LAI) of seven plant functional type
The relative complexity of the mechanisms underlying savanna ecosystem dynamics, in comparison to other biomes such as temperate and tropical forests, challenges the representation of such dynamics in ecosystem and Earth system models. A realistic representation of processes governing carbon allocation and phenology for the two defining elements of savanna vegetation (namely trees and grasses) may
A previous study showed that vibratory stimulation of neck muscles in humans induced short-latency electromyographic (EMG) activation of lower leg muscles, producing postural reactions at the feet. These findings indicated that cervical proprioception contributes to stabilization of stance through rapidly integrated pathways. However, as vibration may excite both proprioceptive and vestibular affe
Mechanical interlock obtained by penetration of bone cement into cancellous bone is critical to the success of cemented total hip replacement (THR). Although acetabular component loosening is an important mode of THR failure, the properties of acetabular cancellous bone relevant to cement penetration are not well characterized. Bone biopsies (9 mm diameter, 10 mm long) were taken from the articula
This study evaluates how strenuous training, age and lameness influence the release of cartilage oligomeric matrix protein (sf-COMP), aggrecan and collagen type II into synovial fluid in 28 (19.5-40 months) Standardbred trotters (STB), during a long-term training programme (24 months). All the horses were trained by the same trainer and were healthy on entering the training programme. Synovial flu
ABO is the most important blood group system in transfusion medicine and transplantation immunology. The ABO blood groups differ by the presence or absence of antigens on RBCs and antibodies in plasma. Accurate determination of ABO status is critical. Genomic typing can increase the precision of blood group determination in complicated cases, e.g. when variant expression of A or B antigen is encou
REDD is one of the latest additions to a series of incentive-based mechanisms for reducing carbon emissions. Although international negotiations have not eliminated uncertainties regarding its social, economic and political implications, many developing and emerging countries have begun to engage in REDD. Peru, the country with the world’s fourth largest tropical forest area has good reason to par
This work concerns an experimental study of pressure drop and heat transfer for turbulent flow inside a U-duct. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. Both friction factors and convective heat transfer coefficients were measured inside a U-duct for three
Popular Abstract in Swedish SAMMANFATTNING PÅ SVENSKA Grupp B streptokocker (GBS) Grupp B streptokocker (GBS), på latin Streptococcus agalactiae, är det vanligaste fyndet vid bakteriella infektioner, som blodförgiftning (sepsis), hjärnhinneinflammation (meningit) och lunginflammation (pneumoni) hos nyfödda barn. Sjukdomsförloppet är ofta våldsamt och livshotande. Sedan 1970-talet har det skett enABSTRACT Streptococci constitute a heterogeneous group of Gram-positive bacteria, divided into different serological groups on the basis of antigenic differences in a cell wall-associated carbohydrate. This thesis describes related surface proteins expressed by bacteria in two of these groups, the group B streptococcus (GBS) and the group A streptococcus (GAS). GBS is an encapsulated bacterium th
Popular Abstract in Swedish Det doktorandarbete som framläggs av Pawel Brühl handlar om flera aspekter av ett framgångsrikt genomfört bullerskyddsarbete i en stor svensk industri med mycket hög bullernivå (Volvos pressverk i Olofström). Man har genomfört ett program bestående av bullermätningar, bullerreduktion med flera metoder samt studium av automatiseringens konsekvenser. Arbetstagarna har fåtThe design and implementation of a hearing conservation programme in a heavy industry with high noise levels is described. Action was taken on several points, including noise measurements, noise reduction, education on hearing protector use, and audiometric monitoring. It was found that the noise at the plant has been greatly reduced during a period of 25 years. The reduction in noise was made pos
The physicochemical properties of two root suspensions, parsnip (Pastinaca sativa) and yacon (Smallanthus sonchifolius), were studied and compared at different concentrations and after being subjected to processes such as homogenization and heating. The study and the evaluation of the physicochemical properties of these plant materials in the form of pastes might help to increase the interest in t
This paper discusses spatial interventions as an important part of women’s struggles to improve their living conditions in poor urban areas. A case-study from San José, Costa Rica is the basis for the discussion. Women’s interventions are analyzed in three public places— a park, a playground and a community centre— through the concept of appropriation. The study shows that women’s interventions ha
Introduction Many studies deal with taxonomic diversity (TD) or estimation of functional traits of ectomycorrhizal communities. However, to our knowledge, none of them has ever tried to calculate the functional diversity (FD) of those communities, which is of critical importance for the diversity and reliability of nutrient supply to the tree. Objectives Here, we propose to evaluate the functional
This study sought to determine whether splenic activation after acute coronary syndrome (ACS) is linked to leukocyte proinflammatory remodeling and whether splenic activity independently predicts the risk of cardiovascular disease (CVD) events.
Hypoxia is emerging as a major threat to marine coastal biota. Predicting its occurrence and elucidating the driving factors are essential to set successful management targets to avoid its occurrence. This study aims to elucidate the effects of warming on the likelihood of hypoxia. High-frequency dissolved oxygen measurements have been used to estimate gross primary production (GPP), net ecosystem
Objectives: To assess outcomes after a pain rehabilitation programme in terms of occupational performance and satisfaction with occupational performance, and to investigate whether socio-demographic factors and pain-related factors were associated with outcomes at follow-up. Methods: A pre- and post-test study of 555 participants with musculoskeletal pain who completed a pain rehabilitation progra
The International Osteoporosis Foundation (IOF) Capture the Fracture Campaign aims to support implementation of Fracture Liaison Services (FLS) throughout the world. INTRODUCTION: FLS have been shown to close the ubiquitous secondary fracture prevention care gap, ensuring that fragility fracture sufferers receive appropriate assessment and intervention to reduce future fracture risk. METHODS: Capt
