Instantaneous threat escape and differentiated refuge demand among zooplankton taxa

Most animals, including aquatic crustacean zooplankton, perform strong avoidance movements when exposed to a threat, such as ultraviolet radiation (UVR). We here show that the genera Daphnia and Bosmina instantly adjust their vertical position in the water in accordance with the present UVR threat, i.e., seek refuge in deeper waters, whereas other taxa show less response to the threat. Moreover, D

DIVERSITY and CHANGE of USER DRIVEN INNOVATION MODES in COMPANIES

User driven innovation (UDI) is a popular term in policy and corporate circles. However, it is not clear exactly what UDI means and how such practices are used across the spectrum of companies and over the innovation life cycle. The present study compares 58 UDI showcases in Finnish companies in order to analyse the diversity of UDI practices and their evolution over time. We identify five main mo

Increasing concentrations of iron in surface waters as a consequence of reducing conditions in the catchment area

Recent studies report trends of strongly increasing iron (Fe) concentrations in freshwaters. Since Fe is a key element with a decisive role in the biogeochemical cycling of major elements, it is important to understand the mechanisms behind these trends. We hypothesized that variations in Fe concentration are driven mainly by redox dynamics in hydraulically connected soils. Notably, Fe(III), which

A new assessment of the alleged link between element 115 and element 117 decay chains

A novel rigorous statistical treatment is applied to available data (May 9, 2016) from search and spectroscopy experiments on the elements with atomic numbers Z = 115 and Z = 117 . The present analysis implies that the hitherto proposed cross-reaction link between α-decay chains associated with the isotopes 293-117 and 289-115 is highly improbable.

Nuclear spectroscopy with Geant4: Proton and neutron emission & radioactivity

With the aid of a novel combination of existing equipment – JYFLTRAP and the TASISpec decay station – it is possible to perform very clean quantum-state selective, high-resolution particle-γ decay spectroscopy. We intend to study the determination of the branching ratio of the ℓ = 9 proton emission from the Iπ = 19/2−, 3174-keV isomer in the N = Z − 1 nucleus 53Co. The study aims to initiate a ser

Explaining low yields and low food production in Cameroon : A farmers' perspective

While a bottom-up approach to identifying problems affecting food production among small-scale farmers has been urged as an appropriate means of finding sustainable solutions, few studies have determined the practical process of doing so and measured the outcomes of such an approach. This paper uses information gained mainly through focus groups with small-scale farmers and semi-structured intervi

Floods in the Douala metropolis, Cameroon : attribution to changes in rainfall characteristics or planning failures?

With urban populations worldwide expected to witness substantial growth over the next decades, pressure on urban land and resources is projected to increase in response. For policy-makers to adequately meet the challenges brought about by changes in the dynamics of urban areas, it is important to clearly identify and communicate their causes. Floods in Douala (the most densely populated city in th

The El Niño – La Niña cycle and recent trends in supply and demand of net primary productivity in African drylands

Inter-annual climatic variability over a large portion of sub-Saharan Africa is under the influence of the El Niño-Southern Oscillation (ENSO). Extreme variability in climate is a threat to rural livelihoods in sub-Saharan Africa, yet the role of ENSO in the balance between supply and demand of net primary productivity (NPP) over this region is unclear. Here, we analyze the impact of ENSO on this

Skådespelarens musikalitet

This investigation takes its point of departure in the prominent use of the term ’musicality’ as a prestige word in theatre discourse where, obviously, not exactly the same reference and meaning is ascribed to the concept as in contexts of music. There seems to be very little previous research in this area, if any. The research question is formulated thus: What do theatre practicians mean when the

Microbiota patterns and risk of cardiometabolic disease - Opportunities for intervention?

In every human being, there is a substantial proportion (1-2 kg) of total body weight constituted by the gut microbiota content in the gastro-intestinal system. Recent research findings, based on mapping of the microbiome, have stated that in healthy subjects, the gut microbiota richness and diversity is higher as compared to obese subjects or patients suffering from cardiometabolic disease, or ev

Evaluation of the possibility to use thick slabs of reconstructed outer breast tomosynthesis slice images

The large image volumes in breast tomosynthesis (BT) have led to large amounts of data and a heavy workload for breast radiologists. The number of slice images can be decreased by combining adjacent image planes (slabbing) but the decrease in depth resolution can considerably affect the detection of lesions. The aim of this work was to assess if thicker slabbing of the outer slice images (where le
