We analyzed a large dataset to quantify adult annual survival probability and remigration intervals for the Tortuguero, Costa Rica green turtle population. Annual survival probability was estimated at 0.85 (95% CI 0.75-0.92) using a recovery model and at 0.85 (95% CI 0.83-0.87) using an open robust design model. The two most common modes of remigration are 2 and 3 years. Annual survival probabilit
In behavioral experiments, the hawkmoth Deilephila elpenor can learn both the color and the position of artificial flowers. When very similar colors are used, moths select the correct color during the first test on a given day, thus using a stimulus strategy, but after repeated rewards, they switch to a place strategy and choose the flower in the position where they received the reward. When dissi
This article contributes to discourse-oriented, information-seeking research by showing how discourses, from a neopragmatist perspective, can be explored as tools that people employ when they actively engage in information practices in varied social contexts. A study of nurses and the nursing profession in Sweden is used as an empirical example of such a context, which is in the article understood
In this work, a three-dimensional computational method has been further developed for a composite duct, to analyze water phase change and liquid water saturation level, two-phase flow and heat transfer in a multi-component mixture. The duct under consideration consists of a flow duct, porous layer and solid structure. Advanced boundary conditions are applied in the analysis, concerning the thermal
Patients with blunt abdominal trauma and fatal outcome during 30 years in a well-defined rural Swedish area have been analyzed. There were 127 patients. Several facts indicate that more severe trauma has been appearing more often during this period The mortality rate has, however, been stable, but the patients have become older. More patients die from pulmonary complications than from the trauma i
We investigated the relationship between trophic status and polychlorinated biphenyl (PCB) distribution in 19 Swedish lakes. We analyzed PCB in water, phytoplankton, zooplankton, fish and sediment during two sampling periods, in spring and summer. The mass of Sigma PCB in the lake sediments was positively related to lake trophy, i.e. more PCBs were accumulated and buried in the sediment of eutroph
In recent years, outcome assessment following different therapeutic procedures has increasingly focused on the patient's perspective. While traditional measures of outcome, including physical examination and imaging diagnostics of the knee are complementary, patient-relevant questionnaires have become more and more important in determining the value of therapeutic procedures. Therefore, there is a
In this paper a combustion diagnostic method is presented where measured pressure data is used to calculate the heat release, local temperatures and concentrations of NO and other species. This is done by a multizone model where the lambda value, i.e. 1/equivalence ratio, in each zone can be chosen arbitrarily. In homogenous charge engines lambda is given by the global air/fuel ratio. The local la
Antisocial behavior is often persistent, and in addition to causing suffering to children and their families, it also poses considerable costs for society. Children who display externalizing behavior in their early years run a high risk of having severe problems later in life. There is a need for treatment methods that may be used in various settings because these children constitute a group that
The green fluorescent protein GFPuv has been genetically engineered to investigate the influence of N-terminal tyrosine extensions in aqueous two-phase systems. Fusions in the N-terminus affected the protein expression, and tags containing three tyrosines and prolines influenced the expression favorably. This effect is probably due to changes in mRNA stability, because the amounts of corresponding
Popular Abstract in Swedish Avhandlingen är en historisk-komparativ analys av en konflikt som har uppstått i Miskito's ekonomiska system under 1900-talet avseende exploateringen av kommunalt ägda resurser. Studien är baserad på empiriskt material insamlat i en Miskito/Creole by på Atlantkusten i Nicaragua på 1990-talet. Under den s k enklavperioden (1860-1960) tjänade Miskito män pengar som lönearThis dissertation is a historical-comparative analysis of a conflict that has developed in the economic system of the Miskito in the 20th century, concerning the use of common property resources. The study is based on empirical material collected in a Miskito/Creole village on the Atlantic Coast of Nicaragua in the 1990s. During the enclave period (1860-1960) Miskito men earned money as wage labou
Popular Abstract in Swedish Kostnaden för utveckling och validering av produktionsanläggningar är idag ett stort problem för farmaceutisk industri. Valideringen innebär normalt en stor experimentell arbetsinsats. Den stora mängden experimentellt arbete innebär att det utvecklas färre läkemedel och till högre kostnad idag jämfört med tidigare. FDA har uppmärksammat detta i sitt PAT initiativ. En mOne of the major issues in the pharmaceutical industry today is the cost of development and validation of the production of the active pharmaceutical ingredients. The development, optimization and validation of a production plant have been dominated by an extensive experimental approach. The large amount of experimental work and reluctance for changing existing processes has caused the pharmaceut
The performance of a turbo code can be severely degraded if no trellis termination is employed. This paper investigates the implications of the choice of trellis termination method for turbo codes, and explains the origin of the performance degradation often experienced without trellis termination. An efficient method to derive the distance spectrum of turbo codes for different trellis termination
Today, as a rule, the most cost-effective way to remove nitrogen from municipal wastewater is the biological method based on nitrification and subsequent denitrification. All biological systems may be affected by toxicants, and biological nitrogen removal is no exception. An investigation of influent wastewaters from 109 Swedish municipal wastewater treatment plants was accomplished. Inhibitory s
Effects of FK506 [5.0 mg/kg body weight (BW), subcutaneous, daily] on nerve regeneration and presence of macrophages in lesioned rat sciatic nerves were studied. Models of autologous nerve graft or a nerve crush lesion were used and regeneration was evaluated by immunocytochemistry (also used to detect ED1/ED2 macrophages) and sensory pinch reflex test, respectively. Treatment with FK506 did not i
Idiopathic facial paralysis, or Bell's palsy, shows a nonepidemic pattern that might indicate reactivation of a latent microorganism such as herpes simplex type I as a causative agent. Thirty percent of patients with Bell's palsy given no treatment will not recover completely, and 5% will have severe sequelae. The aim of this study was to find out whether treatment with an antiviral drug in combin
The importance of different additional simplifications used when moving from single site applications to regional applications of the SAFE and MAKEDEP models was studied. The SAFE model is a dynamic soil chemistry model, which apart from physical and chemical soil parameters also needs the historic evolution of atmospheric deposition and nutrient uptake to simulate the effects of acidic deposition
