Birds, and especially raptors, are believed to forage mainly using visual cues. Indeed, raptors (scavengers and predators) have the highest visual acuity known to date. However, scavengers and predators differ in their visual systems such as in their foveal configuration. While the function of the foveal shape remains unknown, individual variation has never been quantified in birds. In this study,
Grout based on microfine cement is mainly used for sealing of rock fractures in underground construction with high sealing requirements. This grout is known as hard dispersed, compared to grouts based on ordinary Portland cement. This study investigates the possibility of using ultrasound to improve the dispersion of microfine cement grout. Ultrasound dispersion is compared with dispersion efficie
Gel formation by surfactant molecules is generally controlled by thermodynamics rather than kinetics. Mixtures of long-chain alcohols and surfactants are widely used in various cosmetic and pharmaceutical products. The cooling rate used to produce the products is known to be a key parameter to control the rheological properties and the final texture. However, the physical-chemistry links between t
In humans, each hemisphere comprises an overlay of two visuotopic maps of the contralateral visual field, one from each eye. Is the capacity of the visual cortex limited to these two maps or are plastic mechanisms available to host more maps? We determined the cortical organization of the visual field maps in a rare individual with chiasma hypoplasia, where visual cortex plasticity is challenged t
Plant-based beverages are increasing in popularity and quinoa is an attractive option. A hygienic implication linked to the production of beverages from raw material originating from plants is the high microbial contamination. The safety of the product can be guaranteed by lactic acid fermentation, and by using a probiotic strain as starter culture for the fermentation, the final product will bene
In order to gain insights into the biogeographic processes underlying biotic diversification in the Atlantic Forest (AF), we used a multi-locus approach to examine the evolutionary history of the White-shouldered Fire-eye (Pyriglena leucoptera) and the Fringe-backed Fire-eye (Pyriglena atra), two parapatric sister species endemic to the AF. We sequenced one mitochondrial, three Z chromosome-linked
A unique exposure of a strongly deformed late Mesoproterozoic augen-granite (U–Pb zircon age 1146 ± 4 Ma) was detected within rocks on the eastern rim of the West African Craton. These rocks, together with their sedimentary cover, were reworked during the Neoproterozoic Pan-African Dahomeyan orogeny, and are now incorporated in the Dahomeyan orogenic belt of southeast Ghana. To the authors’ knowle
Objective: To achieve the full potential of sentinel lymph node (SLN) detection in endometrial cancer, both presumed low- A nd high-risk groups should be included. Perioperative resource use and complications should be minimized. Knowledge on distribution and common anatomical sites for metastatic SLNs may contribute to optimizing the concept while maintaining sensitivity. Proceeding from previous
We explore the dynamics of income and income inequality under asymmetric information in credit markets. Within a stochastic overlapping-generations framework, we study the investment decision of entrepreneurs with heterogeneous abilities. Under information asymmetry, banks do not observe entrepreneurial ability and offer a single pooled loan contract to all entrepreneurs. We show that, following a
Aim: Specific birth-related fractures have been studied; underestimates might be a problem. We aimed to assess all fractures diagnosed as birth-related as well as other neonatal fractures. Methods: A population-based study on all infants born in Sweden 1997-2014; data were retrieved from the Swedish Health Registers (10th version of International Classification of Diseases. Outcome measures were b
Objective. Evaluate if the use of active clearance of chest tubes after aortic valve surgery influenced bleeding and reduced postoperative residual pericardial effusion. Design. Prospective randomised trial comparing PleuraFlow® 32 F chest tube with FlowGlide™ active clearance to a standard Argyle® 32 F chest tube in 100 patients undergoing aortic valve surgery. Chest tube outputs and pericardial
The strategic direction of the European Union (EU) over the past twenty years has focused on increasing resource productivity and innovation in the economy, aiming at the efficient use and secured supplies of resources, economic growth and job creation, with fewer environmental impacts. One of the basic premises of the new ‘Green Deal’ for Europe is the promotion of the circular economy. The aim o
The STRIPAK complex has been linked to a variety of biological processes taking place during embryogenesis and development, but its role in cancer has only just started to be defined. Here, we expand on previous work indicating a role for the scaffolding protein STRIP1 in cancer cell migration and metastasis. We show that cell cycle arrest and decreased proliferation are seen upon loss of STRIP1 i
Background: Symptoms of depression and anxiety are common in children with obsessive-compulsive disorder (OCD) and associated with more severe OCD, greater impairment, and worse treatment outcome. Beyond twin studies showing that genetic factors contribute to the high co-occurrence, few studies have examined how OCD, depression, and anxiety are linked in youth, and current studies often fail to ac
Much has been written about Percy Bysshe Shelley’s engagement with different aspects of natural philosophy in his poetry and prose. But Shelley’s interest in plants and botany has yet to receive sustained attention. This chapter focusses on the representation of wildness in what it defines as Shelley’s botanical poetry: poems which not only have a plant as their ostensible subject, or which develo
According to the waste hierarchy principle, which constitutes the basis of European waste legislation, waste prevention and re-use are considered – most of the times – better waste management options than recycling. However, prevention and re-use activities are difficult to operationalise and measure, without a monitoring framework in place. This contribution investigates the potential of re-using
Neuroscience focusing on human development and disease has long been hampered due to ethical reasons, low tissue availability, and low translatability from animal models. To circumvent these obstacles, we have developed two methods for the investigation of human neural cells in culture. Firstly, we present a robust 2-week protocol for the differentiation of human pluripotent stem cells (PSCs) into
