Coastal hypoxia is increasing in the global coastal zone, where it is recognized as a major threat to biota. Managerial efforts to prevent hypoxia and achieve recovery of ecosystems already affected by hypoxia are largely based on nutrient reduction plans. However, these managerial efforts need to be informed by predictions on the thresholds of hypoxia (i.e. the oxygen levels required to conserve
The aim of this study was to examine breast density in relation to breast cancer specific survival and to assess if this potential association was modified by mode of detection. An additional aim was to study whether the established association between mode of detection and survival is modified by breast density.
Context: Evidence-based software engineering (EBSE) provides a process for solving practical problems based on a rigorous research approach. The primary focus so far was on mapping and aggregating evidence through systematic reviews. Objectives: We extend existing work on evidence-based software engineering by using the EBSE process in an industrial case to help an organization to improve its auto
Photoemission spectra show that Be(0001) surface states shift to lower energy with increasing Na or K coverage in the monolayer range. At an intermediate monolayer coverage a quantum well state appears near the Fermi edge and shifts to lower energy reaching saturation energy at full monolayer coverage. At full monolayer coverage low energy electron diffraction shows 2 X 2 order for K while Na form
Det kinesiska samhället har blivit alltmer baserat på lag och rätt. Men tyvärr efterlevs inte lagarna. Kommunistpartiets maktmonopol är inte enda hindret för att implementera lagar. Med i bilden finns också svaga institutioner, oklara maktbefogenheter, korruption och bristande kunskaper i rättsfrågor. Den snabba ekonomiska utvecklingen har exempelvis lett till att lokalregeringar ser mellan fingra
The flexibility of implantable neural probes has increased during the last 10 years, starting with stiff materials such as silicone to more flexible materials like polyimide. We have developed a novel polymer based on Off-Stoichiometry Thiol-Enes + Epoxy (OSTE+, consisting of a thiol, two allyls, an epoxy resin and two initiators), which is up to 100 times more flexible than polyimide. Since a fle
Despite our fine-grain anatomical knowledge of the cerebellar cortex, electrophysiological studies of circuit information processing over the last fifty years have been hampered by the difficulty of reliably assigning signals to identified cell types. We approached this problem by assessing the spontaneous activity signatures of identified cerebellar cortical neurones. A range of statistics descri
We have developed a technique so that both transmission electron microscopy and microphotoluminescence can be performed on the same semiconductor nanowire over a large range of optical power, thus allowing us to directly correlate structural and optical properties of rotationally twinned zinc blende InP nanowires. We have constructed the energy band diagram of the resulting multiquantum well heter
This study was designed to investigate attitudes to and incentive for reporting adverse drug reactions (ADRs) in general and towards nurses as reporters of ADRs in particular in a sample of hospital physicians. A questionnaire was sent to 1,201 randomly selected hospital physicians. The main factors for the decision to report an ADR were the severity of the reaction, a reaction to a new drug, and
This study investigated mental workload in basic civil aviation training. Heart rate, eye movement, and subjective ratings from 11 students were collected during simulator and aircraft sessions. Results show high correspondence in psychophysiological reactions between the sessions. For some flight segments, heart rate was consistently lower in the simulator, suggesting higher mental workload in th
Abstract in Polish W artykule przedstawiam ogólne ujęcie relacji wartości. Jako punkt wyjścia przyjmuję szczególny typ relacji wartości, równorzędność, stanowiąca zdaniem Ruth Chang pewną postać porównywalności wartości, która różni się od trzech standardowych postaci porównywalności: lepszości, gorszości i równowartości. Joshua Gert zasugerował niedawno, iż pojęcie równorzędności można wyjaśnić, The paper provides a general account of value relations. It takes its departure in a special type of value relation, parity, which, according to Ruth Chang, is a form of evaluative comparability that differs from the three standard forms of comparability: betterness, worseness and equal goodness. Recently, Joshua Gert has suggested that the notion of parity can be accounted for, if value compariso
This paper brings to the fore the importance of a holistic approach to attaining a general pro-environmental behavioural change in order to reduce carbon emissions and the need to strive for a spillover of pro-environmental behaviour from one area to another. An adjusted version of the MaxSEM model is developed to capture differences in stages of behavioural change regarding environmental load on
Here, we present the activities within our research group over the last five yearswith cantilevers fabricated in the polymer SU-8. We believe that SU-8 is an interestingpolymer for fabrication of cantilevers for bio/chemical sensing due to its simple processingand low Young’s modulus. We show examples of different integrated read-out methodsand their characterisation. We also show that SU-8 cantil
The objective of this study was to evaluate the concentrations of nutrients in stumps and coarse roots in Norway spruce, Scots pine and silver birch in Sweden, Finland and Denmark, and to assess how nutrient concentrations vary with site characteristics, stand age and root size. Concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sodium (Na) in spruce, p
Anemia because of insufficient production of and/or response to erythropoietin (Epo) is a major complication of chronic kidney disease and cancer. The mechanisms modulating the sensitivity of erythroblasts to Epo remain poorly understood. We show that, when cultured with Epo at suboptimal concentrations, the growth and clonogenic potential of erythroblasts was rescued by transferrin receptor 1 (Tf
