The Integrated Use of Dendrochronological Data and Paleoecological Records From Northwest European Peatlands and Lakes for Understanding Long-Term Ecological and Climatic Changes—A Review

Our overall understanding of long-term climate dynamics is largely based on proxy data generated from archives such as ice cores, ocean sediments, tree rings, speleothems, and corals, whereas reconstructions of long-term changes in vegetation and associated climate during the Holocene are largely based on paleoecological records from peat and lake sequences, primarily pollen and plant macrofossil

Core competencies for a biomedical laboratory scientist - a Delphi study

BACKGROUND: After completing university education, biomedical laboratory scientists work in clinical laboratories, in biomedical research laboratories, in biotech, and in pharmaceutical companies. Laboratory diagnostics have undergone rapid development over the recent years, with the pace showing no signs of abatement. This rapid development challenges the competence of the staff and will most cer

Tissue cutting device and system

The present disclosure relates to a tissue cutting system for cutting tissue of a heart, such as tissue of a septum of a heart, comprising: an outer tubular member having a proximal portion and a distal portion, said distal portion comprising a tissue resection window; a resection element axially slidably arranged inside the outer tubular member configured to resect tissue extending through the ti

Mesoporous Silica Formation Mechanisms Probed Using Combined Spin-Echo Modulated Small-Angle Neutron Scattering (SEMSANS) and Small-Angle Neutron Scattering (SANS)

The initial formation stages of surfactant-templated silica thin films which grow at the air-water interface were studied using combined spin-echo modulated small-angle neutron scattering (SEMSANS) and small-angle neutron scattering (SANS). The films are formed from either a cationic surfactant or nonionic surfactant (C16EO8) in a dilute acidic solution by the addition of tetramethoxysilane. Previ

On the reheat furnace control problem

The purpose of this paper is to develop a model and control algorithm for the slab temperature control problem, which is the control of a number of steel blocks (slabs) passing through a furnace burner zone. The slab temperature is controlled by varying the zone temperatrure. First a model for a single slab passing through the furnace is developed and the parameters are estimated. Data from the re

Membranous duodenal stenosis

The experience of our 16 patients treated for membranous duodenal stenosis is reported. Their treatment and course was analysed in a retrospective study. Eight patients were operated on within the first 16 days of life and in the remaining group surgery was performed at 1 month to 4 y of age. The presenting symptom leading to diagnosis was, in all but one case, non-bile-stained vomiting. Associate

First commissioning results of phase i insertion devices at MAX IV Laboratory

An overview of the insertion devices (ID) activities at MAX IV Laboratory will be presented. This paper describes the current status of the MAX IV insertion devices and the first commissioning results of some of the first 12 IDs installed at the three accelerators in MAX IV laboratory. The IDs are two Elliptically Polarizing Undulators (EPU), two In-Vacuum Undulators (IVU) and one In-vacuum wiggle

Fermion masses from symmetry

We present a model with continuous or discrete abelian generation group G, which predicts all orders of magnitude for fermion masses ad mixings correctly as a function of only one small parameter φS M ≈ 1 10. Here φS is the scale of G symmetry breaking and M the fundamental mass scale of the theory. No small Yukawa couplings or special choices of the scalar potential are needed. We perform a syste

Model-based monitoring of industrial reversed phase chromatography to predict insulin variants

Downstream processing in the manufacturing biopharmaceutical industry is a multistep process separating the desired product from process- and product-related impurities. However, removing product-related impurities, such as product variants, without compromising the product yield or prolonging the process time due to extensive quality control analytics, remains a major challenge. Here, we show how

Dynamic urban land-use change management using multi-objective evolutionary algorithms

Frequent land-use changes in urban areas require an efficient and dynamic approach to reform and update detailed plans by re-arrangement of surrounding land-uses in case of change in one or several urban land-uses. However, re-arrangement of land-uses is problematic, since a variety of conflicting criteria must be considered and satisfied. This paper proposes and examines a two-step approach to re

Longitudinal Movement of the Common Carotid Artery Wall : New Information on Cardiovascular Aging

Putative changes in the multiphasic pattern of longitudinal movement of the common carotid artery wall in the normal aging process are unknown. The aim of this study was to explore the phases, and resulting patterns, of the longitudinal movement of the intima–media complex of the human common carotid artery with respect to age and gender. One hundred thirty-five healthy non-smoking patients of dif

Estimation of Power System Inertia from Electromechanical Modes

The inertia of many power systems is expected to decrease as more wind and solar power is introduced. With low inertia, a need to estimate it arises. The estimation method should preferably work during normal operation, in order to ensure that the grid frequency can be maintained during any sudden disturbance. This study proposes a new method for inertia estimation, based on electromechanical mode

The γγ → ηc(1S,2S) transition form factors for two spacelike photons

We discuss γ∗γ∗ → ηc(1S), ηc(2S) transition form factors for both virtual photons. The general formula is given. We use different models for the cc¯ wave function obtained from the solution of the Schrödinger equation for different cc¯ potentials: harmonic oscillator, Cornell, logarithmic, power-law, Coulomb and Buchmüller-Tye. We showed some examples of wave functions in the Light Front represent

On the prognostic value of Heparin-binding protein in Sepsis

Sepsis causes major morbidity and mortality worldwide. There is wide consensus that biomarkers have an important role in sepsis research and patient care. Heparin-binding protein (HBP) is a neutrophil-derived, proinflammatory and vascular permeability-inducing protein and a promising novel sepsis biomarker. In this thesis, we investigate some aspects of the prognostic accuracy and added value of s

State-civil society relations in Gramsci, Poulantzas and Bourdieu: Strategic implications for the degrowth movement

Degrowth thought and strategies suffer from a tension between viewing the state as incapable of initiating transformational change and making a political appeal to it to do precisely this via targeted eco-social policies. While a small number of academic papers has theoretically addressed this tension, there is a lack in research on the strategic implications arising from conceptualizations of the
