The Swedish Navy has operated submarines equipped with air independent propulsion for two decades. This type of submarine can stay submerged for periods far longer than other nonnuclear submarines are capable of. The air quality during longer periods of submersion has so far not been thoroughly investigated. This study presents results for a number of air quality parameters obtained during more th
Mps1 kinase plays an evolutionary conserved role in the mitotic spindle checkpoint [1-8]. This system precludes anaphase onset until all chromosomes have successfully attached to spindle microtubules via their kinetochores [9]. Mps1 overexpression in budding yeast is sufficient to trigger a mitotic arrest, which is dependent on the other mitotic. checkpoint components, Bub1, Bub3, Mad1, Mad2, and
Five parkinsonian patients who had received implants of human embryonic mesencephalic tissue unilaterally in the striatum 10-56 months earlier were grafted with tissue from four to eight donors into the putamen (four patients) or the putamen plus the caudate nucleus (one patient) on the other side, and were followed for 18-24 months. After 12-18 months, PET showed a mean 85% increase in 6-L-[18F]f
In a uniform granite gneiss study area in central Zimbabwe, lineaments oriented parallel to the maximum regional compressive stress orientation exhibit the thickest regolith development, while lineaments oriented perpendicular to the maximum compressive stress show the shallowest development of weathered regolith. The principal fracture set orientations were mapped using aerial imagery. The region
Postural adaptability and responses elicited by vibratory stimulation to the calf muscles recorded on a force platform with eyes open or closed were analyzed in 39 patients suffering from Postural Phobic Vertigo (PPV) (17 men and 22 women, mean age 49 years) and 24 healthy subjects (14 men, 10 women, mean age 38 years). The vibration induced increased body sway in both groups, but the adaptation p
This study investigated the ability of Zen meditators and non-meditators to sustain attention during an ongoing task. We hypothesized that meditators (n = 15) would sustain attention more efficiently than non-meditators (n = 19) by responding faster to task stimuli, making fewer commission errors, and reporting fewer interfering thoughts in the sustained attention to response task (SART). Their mo
In recent work on international comparisons of income-related inequalities in health, the concentration index has been used as a measure of health inequality. A drawback of this measure is that it is sensitive to whether it is estimated with respect to health or morbidity. An alternative would be to use the generalized concentration index that is based on absolute rather than relative health diffe
Although there is abundant evidence that hyperglucagonaemia plays a key role in the development of hyperglycaemia in type 2 diabetes, efforts to understand and correct this abnormality have been overshadowed by the emphasis on insulin secretion and action. However, recognition that the incretin hormone glucagon-like peptide-1 (GLP-1) exerts opposing effects on glucagon and insulin secretion has re
To examine the possible roles of glutamate and aspartate as neurotransmitters in the nucleus submedius (Sm) of rats, the distributions of these amino acids were examined by electron microscopic immunogold labeling. High levels of glutamate were detected in trigeminothalamic tract terminals anterogradely labeled with horseradish peroxidase conjugates. These terminals also displayed a positive corre
The polarisation pattern of skylight offers many arthropods a reference for visual compass orientation. The dung beetle Scarabaeus zambesianus starts foraging at around sunset. After locating a source of fresh droppings, it forms a ball of dung and rolls it off at high speed to escape competition at and around the dung pile. Using behavioural experiments in the field and in the laboratory, we show
Motivational internalism postulates a necessary connection between moral judgments and motivation. In arguing for and against internalism, metaethicists traditionally appeal to intuitions about cases, but crucial cases often yield conflicting intuitions. One way to try to make progress, possibly uncovering theoretical bias and revealing whether people have conceptions of moral judgments required f
The basic precondition for color vision is the presence of at least two receptor types with different spectral sensitivities. The sensitivity of a receptor is mostly defined by the opsin-based visual pigment expressed in it. We show here, through behavioral experiments, that the nymphalid butterfly Heliconius erato, although it expresses short and medium wavelength opsins and only one long wavelen

Background: Opioid-related overdose deaths remain a common cause of death in many settings, and opioid maintenance treatment is evidence-based for the treatment of opioid use disorders. However, access to such treatment varies and is limited in many settings. Methods: The present study examines the longitudinal effects of a regional patient choice reform which substantially increased availability
The use of this material under current conditions is supported by existing information. This material was evaluated for genotoxicity, repeated dose toxicity, developmental and reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, as well as environmental safety. Data show that this material is not genotoxic. Data from the suitable read across anal
Surface roughness is one of the main challenges for the growing industry of additive manufacturing. Not only are surfaces rougher than on components produced by conventional means, but there is also a great variation within a single component as well. In this thesis, we have studied the surface roughness of AM components using focused variant microscope and X-ray computer tomography. This is used
Bananpiren means the Banana pier and the name is a remnant from when ships full of bananas unloaded by the docks. The last banana ship left the wharf in the year of 2000 and since then the pier has mainly been used for different types of temporary events. Apart from when those are held, the pier is abandon with only one sheet shed still standing, as a glimpse of the piers former past as a freeport
Knowledge on how polymeric materials changes or is affected when exposed to products is of interest and importance for many commercial applications. Understanding the product interaction on packaging materials is the key to preventing errors and increasing the quality of products. At Tetra Pak®, product packaging is created to make food and drink safe and accessible everywhere. Therefore, packagin
