The contribution of terrestrially-derived carbon to micro-crustacean zooplankton biomass (i.e. allochthony) has been previously studied in lakes and reservoirs, but little is known about allochthony in rivers. We hypothesized that restricted selective grazing in turbulent environments such as rivers would decouple zooplankton from specific microbial and algal food resources, such that their alloch
Effective societal responses to rapid climate change in the Arctic rely on an accurate representation of region-specific ecosystem properties and processes. However, this is limited by the scarcity and patchy distribution of field measurements. Here, we use a comprehensive, geo-referenced database of primary field measurements in 1,840 published studies across the Arctic to identify statistically
Steady-state laminar natural convection of Cu and TiO2 nanofluids inside different enclosures is numerically investigated. Natural convection is concerned due to a temperature difference between the hot and cold surfaces. The Boussinesq approximation is used to form the governing equations and the commercial software package ANSYS FLUENT version 14.0 is used to numerically solve the governing equa
This paper studies the Clash of Civilizations hypothesis from an economic perspective. Using data on bilateral trade and measures of culture, we evaluate how the impact of cultural differences on trade evolves over time during and after the Cold War. Evidence suggests that the negative influence of cultural differences on trade is more prominent in the post-Cold War era than during the Cold War. F
The contribution of terrestrially derived carbon to micro-crustacean zooplankton biomass (i.e., allochthony) has been previously studied in lakes, reservoirs, and estuaries, but little is known about zooplankton allochthony in rivers. In lacustrine environments, allochthony is regulated by distinct selective feeding behavior of different taxa. However, we hypothesized that restricted possibility f
Tuning of protein surface charge is a fundamental mechanism in biological systems. Protein charge is regulated in a physiological context by pH and interaction with counterions. We report on charge inversion and the related reentrant condensation in solutions of globular proteins with different multivalent metal cations. In particular, we focus on the changes in phase behavior and charge regulatio
After insulin administration in vivo, changes in pancreatic lipase, colipase and amylase contents and outputs were assayed and quantitatively compared. The incorporation of [35S]cysteine into individual enzymes was measured. The mRNA coding for lipase and amylase were determined by dot-blot hybridization. It was found that insulin dose-dependently decreased lipase and colipase contents, but only s
Objectives: The aim of this study was to evaluate our experience with patients affected by ovarian carcinosarcoma. Patients and Methods: During a 16-year period, data on 13 patients with ovarian carcinosarcoma were collected. They were obtained from hospital charts and follow-up visits. Survival curves were estimated by the Kaplan-Meier method and compared using the log-rank test. All tests were t
Suppression of boundary-driven Rayleigh streaming has recently been demonstrated for fluids of spatial inhomogeneity in density and compressibility owing to the competition between the boundary-layer-induced streaming stress and the inhomogeneity-induced acoustic body force. To understand the implications of this for acoustofluidic particle handling in the submicrometer regime, we here characteriz
The aim of the present study was to investigate psychodynamic psychotherapists’ experience of the influence of personal therapy on professional growth during training with a focus on the acquisition of knowledge and the development of psychotherapeutic skills. Thematic analysis was conducted on interviews with former students (N=10) at two training institutes for psychoanalytic psychotherapy. The
Popular Abstract in Swedish Avhandlingen påbörjades 1997 vid den Psykiatriska Rehabiliteringsenheten (PRE) i Eslöv parallellt med att författaren arbetade som klinisk psykolog vid enheten och utförde bedömningar av patienternas intellektuella/kognitiva förmåga och personlighet. Resultaten från dessa bedömningar kom tillsammans med andras bedömningar att utgöra underlaget för den individuella vårdpThese studies were conducted at the Psychiatric Rehabilitation Unit (PRU), characterised by a supportive ego-strenghtening psychodynamic approach. The general aim of the thesis was to study how intellectual ability and perceived self-image were related to perceived ward atmosphere among patients with psychosis. The first study described how patients and staff perceived the ward atmosphere at five
Popular Abstract in Swedish Bakgrund Järn (med den kemiska beteckningen Fe, från latinets ferrum) är känt för de flesta som en beståndsdel i till exempel stål. Det många inte vet är att järn är nödvändigt för liv, så som det ser ut på jorden idag. Men det finns en annan sida av myntet: järn kan nämligen också vara giftigt. Som de allra flesta känner till rostar järn i närvaro av syre och vatten.Patients suffering from the deadly progressive neurodegenerative disease Friedreich's ataxia have reduced levels of expression of the protein frataxin. Yeast frataxin has been extensively studied in vitro, and has been shown to deliver iron to heme and iron-sulfur cluster biosynthesis, as well as to oligomerize in the presence of iron. In this dissertation metal-dependent oligomerization of fratax
This thesis reports a study involving the use of Halomonas boliviensis, a moderate halophile, for production of biopolyester poly(3-hydroxybutyrate) (PHB) and compatible solutes ectoine and hydroxyectoine through high cell-density cultivation comprising fed-batch cultures. PHB is a biodegradable plastic produced by bacteria as energy reserve and can potentially be used as a replacement of fossil b
