The Swedish youth organization Fältbiologerna was founded in 1947 with the mission to inspire learning about nature through outdoor activities. Since then, the members have stayed true to their slogan ‘keep your boots muddy’ through engaging in bird watching and forest excursions; however, in the late 1960s and early 1970s – a period that environmental historians refer to as the ‘ecological turn’
Plant organelle function must constantly adjust to environmental conditions, which requires dynamic coordination. Ca(2+) signaling may play a central role in this process. Free Ca(2+) dynamics are tightly regulated and differ markedly between the cytosol, plastid stroma, and mitochondrial matrix. The mechanistic basis of compartment-specific Ca(2+) dynamics is poorly understood. Here, we studied t
BACKGROUND: When used correctly, dermoscopy is an essential tool for helping clinicians in the diagnosis of skin diseases and the early detection of skin cancers. Despite its proven benefits, there is a lack of data about how European dermatologists use dermoscopy in everyday practice.OBJECTIVES: To identify the motivations, obstacles and modifiable factors influencing the use of dermoscopy in dai
The protein corona formed around nanoparticles in protein-rich fluids plays an important role for nanoparticle biocompatibility, as found in several studies during the last decade. Biological fluids have complex compositions and the molecular components interact and function together in intricate networks. Therefore, the process to isolate blood or the preparation of blood derivatives may lead to
Lamb modes with zero group velocity at nonzero wave numbers correspond to local and stationary resonances in isotropic plates. Lamb modes can be utilized for nondestructive evaluation of the elastic properties and thickness. One example of an application is the testing of plate-like concrete structures. In this example, continuous variation in the material velocity through the thickness may occur.
Adaptation to temperature regimes and host presence may enhance fitness in parasites. In an experimental study, we evaluated the timing of glochidia release by Unio crassus subjected to three spring water temperature regimes in the presence and absence of the host fish Cottus gobio. The timing of glochidia release was delayed at (i) constantly low temperatures (<10°C), in contrast to earlier and p
In this article, I address how the history of intellectual disability politics is made sense of in social scientific research and popular discourse. In particular, I discuss the construction of a narrative break between a past of institutionalisation and the present policies of citizenship. By drawing on how postcolonial theorists criticise common ideas about decolonisation, I argue that this narr
We investigated whether dementia risk factors were associated with prodromal Alzheimer's disease (AD) according to the International Working Group-2 and National Institute of Aging-Alzheimer's Association criteria, and with cognitive decline. A total of 1394 subjects with mild cognitive impairment from 14 different studies were classified according to these research criteria, based on cognitive pe
The trigeminal ganglion plays a key role in primary headache pathophysiology. Calcitonin gene-related peptide (CGRP) and CGRP receptors are expressed in trigeminal neurons that form C-fibers and A-fibers, respectively. In acute migraine and cluster headache attacks, there is release of CGRP into the cranial venous outflow. In addition, intravenous CGRP can induce migraine-like symptoms in migraine
The Dark Triad (i.e., Machiavellianism, narcissism and psychopathy) is a popular construct for describing socially aversive personality traits. In recent years, the Short Dark Triad (SD3; Jones & Paulhus, 2014) has become a popular measure for assessing the Dark Triad constructs. However, recent research has called the supposed dissimilarity between the Dark Triad constructs into question. In
We report on the study of six similar buildings built in an area of Gothenburg, Sweden,in 1971, which are now in urgent need of renovation. However, the owner of thebuildings - a municipal housing company did not achieve a financially viablerenovation of the pilot project. This meant that renovation on a similar basis for theremaining five buildings would not be possible. For this reason the housi
Genetic polymorphisms are powerful model systems to study the maintenance of diversity in nature. In some systems, polymorphisms are limited to female coloration; these are thought to have arisen as a consequence of reducing male mating harassment, commonly resulting in negative frequency-dependent selection on female color morphs. One example is the damselfly Ischnura elegans, which shows three f
Embedded in the Western scientific rationality Hofstede’s methodological approach is constructed on a quantitative method characterized by a carefully selected sample of well educated white ‘men’ from the middle classes working for the same company and sharing similar occupation. The appointment of these men as the norm for national culture might mislead one to believe that Hofstede perceive of cu
Eukaryotic protein kinases, containing a conserved catalytic domain, represent one of the largest superfamilies of the eukaryotic proteins and play distinct roles in cell signaling and diseases. Near completion of rat genome sequencing project enables the evaluation of a near complete set of rat protein kinases. Publicly accessible genetic sequence databases were searched for rat protein kinases,
