As animals move through their environments they are subjected to an endless barrage of sensory signals. Of these, some will be of utmost importance, such as the tell-tale aroma of a potential mate, the distinctive appearance of a vital food source or the unmistakable sound of an approaching predator. Others will be less important. Indeed some will not be important at all. There are, for instance,
Objective: To investigate whether women raised in a family with substance abuse constitute a particularly vulnerable group of patients in an infant psychiatry setting and to identify the risk factors of suspected parental malfunctioningin women referred to treatment in an infant and toddler intervention program.Background: A history of family substance abuse can severely disrupt the caretaking abi
Aspergillus niger-treated dry olive cake (DryOC) can be used as a soil organic amendment and the aim of this work was to study the effectiveness of this amendment and a Cd-adapted arbuscular mycorrhizal (AM) fungus in improving Trifolium repens growth and nutrition in Cd-contaminated soil. In a compartmentalized growth system, consisting of a root compartment (RC) and two hyphal compartments (HCs)
Many species from diverse taxa are known to display synchronous fluctuations across vast geographical ranges. It is often thought that climate factors influencing the growth of conspecific populations are correlated over large distances and hence produce the synchronous population dynamics - an effect known as the Moran effect. However, for species embedded in a food web the Moran effect needs not
Objective To evaluate the association between objectively measured daily Study design Cross-sectional, observational, study of 248 children aged 7.9 to 11.1 years. Abdominal fat mass and total body fat mass were measured by dual-energy X-ray absorptiometry. Daily physical activity was assessed by accelerometers for 4 days. Results Total body fat expressed as a percentage of body mass was inversely
Energy-rich methane can be harnessed from seaweed deposits by anaerobic digestion. However, the high heavy metal content in the seaweed and its digestates limits their use as fertilisers. Heavy metal contaminants from solid seaweed can be removed by, mobilisation into a liquid phase and subsequent metal ions adsorption. In this laboratory-scale study, pretreatment strategies for enhancing seaweed
Aims: Multiple lines of evidence have implicated beta-amyloid (A beta) in the pathogenesis of Alzheimer's disease (AD). However, the mechanism(s) whereby A beta is involved in the disease process remains unclear. The dominant hypothesis in AD has been that A beta initiates the disease via toxicity from secreted, extracellular A beta aggregates. More recently, an alternative hypothesis has emerged
In this study a modified mid-ranging strategy is proposed where the controller for the secondary manipulated variable uses its own output as its setpoint, possibly with an offset and/or re-scaling. This modification allows the manipulated variables to increase in unison so that the mid-ranging advantage of utilizing the fast dynamics of the primary controller to regulate the process can be achieve
The aims of this study were to describe which occupations that people with late effects of polio perceive difficult to perform, which occupational area the occupations were related to and their level of complexity. The aims were also to describe their own perception of the importance, performance and satisfaction with these occupations. Sixty-two participants (mean age 61years) were assessed with
The population of metastable states produced in relativistic-energy fragmentation of a U-238 beam has been measured. For states with angular momentum greater than or similar to 20h, a much higher population than expected has been observed. By introducing a collective component to the generation of angular momentum the experimental data can be understood. This is the first time that a collective de
The use of molecularly imprinted polymers (MIPs) in chemical and bioanalytical applications has been gaining in interest in recent years. Compared to their biological receptor counterparts, MIP's are easy to prepare, have long shelf stability and can be used under a variety of harsh conditions. The majority of MIPs currently used are produced by traditional free radical polymerization. One drawbac
We present a theoretical analysis of the interfacial tensions of microemulsions in ternary systems water-oil-nonionic surfactant. For surfactants based on oligo-ethylene oxide head-groups the temperature can be used to tune the properties of the microemulsions. Explicit expressions are derived for the interfacial tension of both droplet and bicontinuous microemulsions. We also discuss the effect o
Background Sensory information from mechanoreceptors in the skin, muscles, tendons, and joint structures plays an important role in joint stability. A joint injury can lead to disruption of the sensory system, which can be measured by proprioceptive acuity. When evaluating proprioception, assessment tools need to be reliable. The aim of this study was to assess the test-retest reliability of a de
Galectin-4 belongs to a subfamily of galectins composed of two carbohydrate recognition domains within the same peptide chain. The two domains have all the conserved galectin signature amino acids, but their overall sequences are only approximately 40% identical. Both domains bind lactose with a similar affinity as other galectins, but their respective preferences for other disaccharides, and larg
Stress-related exhaustion is an increasingly focused phenomenon, although scientifically not yet fully conceptualised. This is perhaps partly due to the fact that the distinction between exhaustion and other already established concepts, such as depression, is not clear. This study explores whether exhaustion can be differentiated from depression and anxiety, by means of introducing the SF-36 vita
A procedure was developed for the covalent coupling of anti-alpha-fetoprotein antibody (anti-AFP) to a gold surface modified with a self-assembled monolayer (SAM) of thiourea (TU). The performance of the SAM-antibody layer was compared to those of similar layers based on thioctic acid (TA) and 3-mercaptopropionic acid (MPA) by using flow injection capacitive immunosensor system. Covalent coupling
Tumor-associated trypsin inhibitor (TATI) is a marker of mucinous ovarian carcinoma, but it is also widely expressed in other malignant tumors and normal human tissues. Elevated serum concentrations of TATI are of prognostic value in ovarian, kidney, and bladder cancer. Tumor-associated trypsin is co-expressed with TATI in many malignancies and is thought to be involved in tumor invasion. TATI mRN
High-Level Grafchart is a graphical programming language for control of sequential processes. Sequential control is important in all kinds of industries: discrete, continuous and batch. Sequential elements show up both on the local control level and on the supervisory control level. High-Level Grafchart combines the graphical syntax of Grafcet/SFC with high-level programming language constructs an
Different strategies for reducing emissions of nitrogen oxides and carbon dioxide from the Swedish transportation sector are evaluated by making scenarios for the year 2015, using a bottom-up approach. Methods for reducing emissions of carbon monoxide, hydrocarbons, and sulphur dioxide are discussed more briefly. The scenarios are based on official forecasts of future passenger and goods transport
