In view of the grazing optimization theory, we examined the effects of different intensities of grazing by the enchytraeid Cognettia sphagnetorum (Vejdovsky) on microbial respiration and hyphal length in soil. In a feeding experiment we established that C. sphagnetorum feeds on the fungus Mortierella isabellina (Oudem) and that the worms disperse fungal propagules. Grazing of C. sphagnetorum with

Controllable particle assisted growth (PAG) of III-V nanowires is today almost exclusively done with Au, Ga or In nanoparticles, whereas other metals often yield nanowires with uncontrolled growth directions. To improve the control of the initial growth direction in PAG, independent of choice of metal, we propose to initiate nanowire growth from a group-III-rich foreign metal particle. For III-V n

1. Dispersal in a fungivore species of Collembola, Onychiurus armatus, in a homo- geneous soil was theoretically approached as a deterministic compartmental process, in which the movement of animals between discrete patches could be described by a series of differential equations or by the discrete geometric probability distribution, assuming a constant probability to move from one patch to the ne

The compensatory growth potential of a grazed fungal biomass was mathematically expressed as a function of patchiness in its distribution and demonstrated in an experiment using the fungivorous collembolan Onychiurus armatus and the soil fungi Verticillium bulbillosum and Penicillium spinulosum. The model addresses the regrowth potential in relation to patch fragmentation, travelling time and cons

The olfactorial response of the fungivorous soil collembolan Onychiurus armatus was examined in a bioassay covering volatile compounds identified in the odor blends of two of its preferred fungal species Monierella isabellina and Verticillium bulbillosum. The odor of the fungi was trapped using activated carbon filters, extracted with diethyl ether, and subjected to GC-MS analysis. About 50% of th

Hyphal morphology and extracellular enzyme production of the fungus Mortierella isabellina were studied during grazing by a soil Collembola, Onychiurus armatus. Grazing induced switching from a "normal" hyphal mode, with appressed growth and sporulating hyphae, to fan shaped sectors of fast growing and nonsporulating mycelium which developed extensive aerial mycelium. Specific protease and α-amyla

Both male and female Orchesella cincta (Collembola) were able to discriminate between spermatophores of different origin. Females chose spermatophores deposited by closely related males while males preferentially destroyed spermatophores of other males.

This paper presents two cases from royal media scandals, journalism, rumours and street slandering. The investigation comprices the late 19th century to the early 21st. Our chosen scandals have Swedish kings and presumed and forbidden sexuality in centre of focus. The first scandal took place in the late 19th century, the second in the early 21st century.Via the concept of media system we track th

Background: It is important to quantify a static posture to evaluate the need for and effectiveness of interventions such as physical management, physiotherapy, spinal orthosis or surgical treatment on the alignment of body segments. Motion analysis systems can be used for this purpose, but they are expensive, require a high degree of technical experience and are not easily accessible. A simpler m

Brain iron accumulation is common in patients with Parkinson's disease (PD). Iron chelators have been investigated for their ability to prevent neurodegenerative diseases with features of iron overload. Given the non-trivial side effects of classical iron chelators, lactoferrin (Lf), a multifunctional iron-binding globular glycoprotein, was screened to identify novel neuroprotective pathways again

Objective: To survey potential predictors of success of mandibular advancement device (MAD) therapy in patients with obstructive sleep apnea (OSA), and in particular, to examine anatomical narrowings and sleep-related collapse levels in the upper airway. Methods: This was a prospective study of 62 OSA patients (median apnea–hypopnea index [AHI] of 34), who were treated with a custom-made, monobloc

This article started out as a keynote lecture at the ‘Coarseness of the Brontës: A Reappraisal’ conference in Durham on 10-11 August 2017. It raises issues in which the ‘coarseness’ of The Tenant of Wildfell Hall (1848) - its most striking characteristic, according to censorious 1848 reviewers - is a central element. These issues include the violent Hattersley marriage, the manifestations of physi

As cell and molecular biology is becoming increasingly quantitative, there is an upsurge of interest in mechanistic modeling at different levels of resolution. Such models mostly concern kinetics and include gene and protein interactions as well as cell population dynamics. The final goal of these models is to provide experimental predictions, which is now taking on. However, even without matured

Aptitude for and proficiency in acquiring new languages varies in the human population but their neural bases are largely unknown. We investigated the influence of cortical thickness on language learning predictors measured by the LLAMA tests and a pitch-change discrimination test. The LLAMA tests are first language-independent assessments of language learning aptitude for vocabulary, phonetic wor

Aim: This study examined medical and psychosocial risk factors in children born to women with addiction problems during pregnancy and the children's needs for extra medical and psychosocial resources. Methods: Swedish midwives routinely screen pregnant women for drugs and alcohol and refer women with addictions to the Maternity and Child Healthcare Resource Team. We investigated the medical record

SeeMe is a pedestrian crosswalk warning system with automatic pedestrian detection that is mounted on crosswalk signs. Amber flashing lights are activated when pedestrians are approaching or crossing the crosswalk. The aim is to attract motorists’ attention, to improve yielding behavior and to reduce conflicts. A before-after study with a matched comparison group has been conducted in the Norwegia

Fishers are often perceived to be poor, and low income levels are used to justify subsidies and other types of direct and indirect income support to maintain coastal communities. In this study fishers’ income levels are investigated in four Nordic countries; Denmark, Iceland, Norway and Sweden for different types of fishers and vessels and in comparison to alternative occupations. The most importa
