During recent decades we have witnessed growing scientific concern, public debate and media attention concerning the possible adverse effects on humans and wildlife that may result from exposure to a wide range of environmental contaminants. These contaminants are called endocrine disrupters, or endocrine-disrupting compounds (EDCs) and are defined as chemicals that interfere with the function of
Target-specific molecular imaging with radiolabeled antibodies has experienced a rapid growth over the past 20 years, and is now an essential tool to provide information on disease presence and extent. Despite all efforts to detect and control prostate cancer at an early stage, a number of men are still progressing to develop incurable metastatic disease. Because of this, development of new method
Aerodynamic four-way coupling models are necessary to handle two-phase flows with a dispersed phase in regimes in which the particles are neither dilute enough to neglect particle interaction nor dense enough to bring the mixture to equilibrium. We include an aerodynamic particle interaction model within the framework of large eddy simulation together with Lagrangian particle tracking. The particl
We report on the particle assisted synthesis of core-shell AlP-GaP nanowires by use of metal-organic vapor phase epitaxy. The core-shell approach is chosen such as to stabilize the AlP which is highly sensitive to water. The nanowires were investigated by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Raman spectroscopy. These nanowires have an indirect band
This article explores the proposition that a reason for high agricultural productivity in the early nineteenth century was relatively high energy availability from draught animals. The article is based on the collection of extensive new data indicating different trends in draught power availability and the efficiency of its use in different countries of Europe. This article shows that the proposit
The transfer of 210Po and 210Pb between various compartments in the terrestrial environment has been analysed by using various published data. The average activity concentration of 210Po in soil is 61 ± 14 Bq.kg-1 d.w. with a median (50%) value of 44 Bq.kg-1 d.w. Ground water concentrations of 210Po in drilled wells might be as high as 6.5 Bq/l. But in regular drinking water it is just about 3-5
Balance disorders are common in elderly people, not only resulting in distressing sensations but also leading to reduced activity levels and quality of life. It has been estimated that 30% of elderly patients experience a balance disorder. Managing these disorders is a substantial challenge for patients and their caregivers and physicians. Moreover, abnormalities in balance are associated with fal
The efficacy of serotonin reuptake inhibitors in depression and anxiety disorders suggests the gene coding for the serotonin transporter (5-HTT), SLC6A4, as a candidate of importance for these conditions. Positive findings regarding associations between polymorphisms in SLC6A4 have been reported, indicating that these polymorphisms may influence anxiety-related personality traits, as well as the r
Anopheles gambiae is the predominant malaria vector species in Ghana, western Africa, with a strong local presence of Anopheles melas Theobald along the southern coast. We studied the biting behavior of these two species of the Anopheles gambiae complex inland and at the coast in Ghana, with special attention to the local peoples' preference for outdoor sleeping. We collected mosquitoes at two sit
An archeological excavation is usually a rapidly evolving environment: several factors (weather, costs, permissions) force the work to be concentrated in a few weeks. Moreover, excavating is essentially a mono-directional operation, which constantly modifies the state of the site. Since most of the interpretation is performed in a second stage, it is necessary to collect a massive amount of docume
Syftet med denna rättssociologiskt inriktade artikel är att beskriva och problematisera lag-stiftnings- och regleringsprocesser av skolans uppdrag med fokus på miljö och hållbar ut-veckling, och samtidigt beskrivs den historiska bakgrunden för denna tematik 1990-2011. Vi tolkar de rättsliga och politiska skeendena och de involverade institutionerna i ett teoretiskt, historiesociologiskt perspektiv
Based on sequence and phylogenetic analyses, glycoside hydrolase (GH) 3 can be divided into several clusters that differ in the length of their primary sequences. However, structural data on representatives of GH3 are still scarce, since only three of their structures are known and only one of them has been thoroughly characterized-that of an exohydrolase from barley. To allow a deeper structural
Structural properties and the topology of polyelectrolyte complexes (PECs) formed in solution have been investigated under different conditions by Monte Carlo simulations using a coarse-grained model. The extension of individual polyions has been characterized by their radius of gyration, whereas the composition of the complexes has been investigated by their net charge and their internal topologi
Objective To study intraobserver repeatability and intermethod agreement between two- (2D) and three-dimensional (3D) transperineal ultrasound methods in assessing fetal head descent during the first stage of labor. Methods Fetal head descent was measured with transperineal ultrasound as the fetal head-perineum distance and the angle of progression in 106 primiparous women with prolonged first sta
There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. Here we show that, while the contribution of wild bees to crop production is significant, service delivery is
To be an effective mentor at any level is always a challenge and requires a dedication to teaching and mentorship and being prepared to devote a significant proportion of one's time. But if you are open-minded and deeply care for your mentee, you have the opportunity to be a successful mentor. This presentation is based on personal experience of mentoring radiology residents, doctoral students, an
Understanding the mechanisms of complex polygenic diseases like type 2 diabetes (T2D) is as complex as their nature. Cellular processes involved in glucose homeostasis need high and reliable energy supply. Mitochondria are the major energy producers in mammalian cells. Since majority of the mitochondrial genes are encoded by the nuclear genome, a tightly regulated and coordinated nuclear-mitochond
Girls and boys with disabilities, 15-16 years of age, report a significantly higher rate of sexual debut than adolescents with no disabilities. In a society where a young person with a disability often is considered to have an essentially asexual status, there can be several fronts for adolescents to fight. The survey Life and Health-Young People 2005 was completed by 3,084 adolescents attending m
