We verified an active uptake of kleptoplastids in the toxic and bloom-forming dinoflagellates of the genus Dinophysis from its preferred prey, the ciliate Myrionecta rubra, using a quantitative real-time PCR technique. During a 65 d starvation/feeding experiment with Dinophysis caudata, changes in plastid 16S rRNA, plastid autofluorescence and plastid/nuclear DNA ratio through the cell cycle were
Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. Applications from both process automation, manufacturing, and robotics have been considered.
Traditionally, multi-family houses have been constructed using heavy, homogenous materials like concrete and masonry. But as a consequence of the progress of lightweight building systems during the last decades, it has been questioned whether standardized sound insulation evaluation methods still are appropriate. An extensive measurement template has been applied in a field survey where several vi
Laminar burning velocities of dimethyl carbonate (DMC) + air flames at initial gas mixture temperatures of 298, 318, 338, and 358 K are reported. Nonstretched flames were stabilized on a perforated plate burner at atmospheric pressure, and the laminar burning velocities were determined using the heat flux method. The overall accuracy of the burning velocities was evaluated to be typically better t
The factors that drive partial migration in organisms are not fully understood. Roach (Rutilus rutilus), a freshwater fish, engage in partial migration where parts of populations switch between summer habitats in lakes and winter habitats in connected streams. To test if the partial migration trait is phenotypically plastic or has genetic components, we translocated roach from 2 populations with d
We present in detail a method we recently introduced [Phys. Rev. Lett. 103, 176404 (2009)] to describe finite systems in and out of equilibrium, where the evolution in time is performed via the Kadanoff-Baym equations within many-body perturbation theory. Our systems consist of small, strongly correlated clusters, described by a Hubbard Hamiltonian within the Hartree-Fock, second Born, GW, and T-m
Endotoxemic liver injury is characterized by an initial release of pro-inflammatory cytokines and CXC chemokines, which leads to a recruitment of leukocytes to the liver microvasculature. The mechanisms of leukocyte recruitment are well characterized and comprise on the one hand a mechanical trapping of leukocytes in sinusoids, and on the other hand a multi-step process of leukocyte-endothelial ce
To improve the mechanical characteristics of actively controlled continuous faceplate deformable mirrors in adaptive optics, a strategy for reducing crosstalk between adjacent actuators and for suppressing low-order eigenmodes is proposed. The strategy can be seen as extending Saint-Venant's principle beyond the static case, for small local families of actuators. An analytic model is presented, fr
This paper presents measurement results of electricity use and lighting conditions in individual office rooms located in Lund, Sweden. The aim is to demonstrate the energy saving potential by using different lighting systems and the satisfaction of users. The measurements are carried out in one empty reference room and four fully occupied test rooms equipped with different electric light control s
Acoustic trapping of minute bead amounts against fluid flow allows for easy automation of multiple assay steps, using a convenient aspirate/dispense format. Here, a method based on acoustic trapping that allows sample preparation for immuno-matrix-assisted laser desorption/ionization mass spectrometry using only half a million 2.8 mu m antibody covered beads is presented. The acoustic trapping is
Methods were developed for post-detection and early-warning of defoliation in Scots pine [Pinus silvestris] forests in south-eastern Norway caused by the pine sawfly [Neodiprion sertifer] with the use of multi-temporal MODIS NDVI 16-day composite data. The post-detection method utilizes summer mean values and seasonal angle (showing whether values have increased or decreased during the season) to
In this paper we introduce two new methods for constructing harmonic morphisms from solvable Lie groups. The first method yields global solutions from any simply connected nilpotent Lie group and from any Riemannian symmetric space of non-compact type and rank r ≥ 3. The second method provides us with global solutions from any Damek–Ricci space and many non-compact Riemannian symmetric spaces. We
Popular Abstract in Swedish Idag har patienter med blodcancer (leukemi) eller genetiskt betingade blodsjukdomar (sickelcellanemi etc.) begränsad tillgång till behandlingar som effektivt och riskfritt botar sjukdomstillståndet. Detta arbete inkluderar forskningsresultat ämnade att bidra till utveckling av konceptuellt nya behandlingsmetoder för olika typer av blodsjukdomar. Ett fungerande blodsysteThere is a pressing need for compatible Hematopoietic Stem Cells (HSCs), in high quantities and of good clinical quality, to ensure optimal treatment for patients with various blood malignancies. Pluripotent Stem Cells (PSCs) have the potential to be a source for generating HSCs. The indefinite expansion capacity of PSCs, combined with the possibility of creating these cells from patient-specific
Background: Air pollution, mainly from combustion, is one of the leading global health risk factors. A susceptible group is the more than 200 million people worldwide suffering from chronic obstructive pulmonary disease (COPD). There are few data on lung deposition of airborne particles in patients with COPD and none for combustion particles. Objectives: To determine respiratory tract deposition o
This article presents the notion of spatial justice as a way of considering the relationship between law and street art in a manner beyond the legal/illegal dichotomy. Through a series of empirical examples, it is demonstrated how street art literally takes a place already taken and imposes itself in an already appropriated urban public space. Street art thus ´redefines the space in contestation t
LuCuGaO4 has magnetic Cu2+ and diamagnetic Ga3+ ions distributed on a triangular bilayer and is suggested to undergo a spin glass transition at T-g similar to 0.4 K. Using mu SR (muon spin rotation) and neutron scattering measurements, we show that at low temperature the spins form a short range correlated state with spin fluctuations detectable over a wide range of timescales: at 0.05 K magnetic
The discovery of the key role of Toll-like receptors (TLRs) in initiating innate immune responses and modulating adaptive immunity has revolutionized our understanding of vertebrate defence against pathogens. Yet, despite their central role in pathogen recognition and defence initiation, there is little information on how variation in TLRs influences disease susceptibility in natural populations.
Simultaneous detection of multiple-gas species has for the first time (to our knowledge) been demonstrated by using a multimode diode-laser-based correlation spectroscopy (MDL-COSPEC) scheme. Concentration measurements of a mixture of CO2 and CO gas were performed by probing overlapping line spectra around 1.57 mu m using an MDL. Species identification and corresponding quantitive analysis were im
