The traditional view of the planktonic food web describes consumption of inorganic nutrients by photoautotrophic phytoplankton, which in turn supports zooplankton and ultimately higher trophic levels. Pathways centred on bacteria provide mechanisms for nutrient recycling. This structure lies at the foundation of most models used to explore biogeochemical cycling, functioning of the biological pump

We present optical methods at a wide range of wavelengths for remote classification of birds. The proposed methods include eye-safe fluorescence and depolarization lidar techniques, passive scattering spectroscopy, and infrared (IR) spectroscopy. In this paper we refine our previously presented method of remotely classifying birds with the help of laser-induced beta-keratin fluorescence. Phenomena

Nanowires have the potential to play an important role for next-generation light-emitting diodes. In this work, we present a growth scheme for radial nanowire quantum-well structures in the AlGaInP material system using a GaInP nanowire core as a template for radial growth with GaInP as the active layer for emission and AlGaInP as charge carrier barriers. The different layers were analyzed by X-ra

The superiority of positron emission tomography (PET) with 2-deoxy-2-[18F]fluoro-D-glucose (FDG) over computed tomography and magnetic resonance imaging in detecting recurrent cervical cancer and determining the extent of the disease has been demonstrated in several clinical trials. However, there is a lack of data concerning the clinical impact of the extra findings. We report here a prospective

Epitaxial layers of (Ga,Mn)As ferromagnetic semiconductor have been subjected to low-energy ion implantation by applying a very low fluence of either chemically active, oxygen ions or inactive ions of neon noble gas. Several complementary characterization techniques have been used with the aim of studying the effect of ion implantation on the layer properties. Investigation of their electrical and

To array rare cells at the single-cell level, the volumetric throughput may become a bottleneck in the cell trapping and the subsequent single-cell analysis, since the target cells per definition commonly exist in a large sample volume after purification from the original sample. Here, we present a novel approach for high throughput single cell arraying by integrating two original microfluidic dev

We investigated the relationship between organizational factors and three dimensions of burnout in a sample of 53 Swedish public librarians. We also qualitatively identified specific library-related stressors based on the organizational factors investigated. The results showed that the organizational factors workload and community predicted higher levels of emotional exhaustion while the organizat

2-Oxoglutaric acid (2-Ox), a precursor to hydroxyproline - the most abundant amino acid in bone collagen, exerts protective effects on bone development during different stages of organism development; however, little is known about the action of 2-Ox on cartilage. The aim of the present study was to elucidate the influence of dietary 2-Ox supplementation on the growth plate, articular cartilage an

To determine whether health-related lifestyle factors are associated with attendance at a population-based invitational mammography screening program in southern Sweden, data on health-related lifestyle factors (smoking, alcohol use, physical activity, BMI, diet, self-rated health, and stress) were obtained from the Malmö Diet and Cancer Study and linked to the Malmö mammography register (Sweden,

This article examines the economic consequences of widowhood and the possibility of maintaining female-managed farms in a predominantly male world. A unique dataset is exploited to investigate the productivity of female-headed households in preindustrial Sweden. The main source material is tithe payment rolls maintained by parish priests, which reflect fluctuations and long-term trends in the annu

In situ Zn doping of InP shells on nanowires in the wurtzite crystal structure has been investigated using diethyl zinc (DEZn) as a precursor. Photoluminescence measurements of single nanowires unexpectedly exhibit an acceptor-related peak at room temperature, in contrast to thin films grown at identical conditions. This peak is observable even using low DEZn molar fractions, which indicates effic

Measurements of fiducial and differential cross sections are presented for Higgs boson production in proton-proton collisions at a centre-of-mass energy of TeV. The analysis is performed in the H -> gamma gamma decay channel using 20.3 fb(-1) of data recorded by the ATLAS experiment at the CERN Large Hadron Collider. The signal is extracted using a fit to the diphoton invariant mass spectrum assum

To report contemporary outcomes, and evaluate differences after thrombolysis for occluded endoprosthesis, bypasses and native artery occlusion in patients with lower limb ischemia.

We measured the He and Ne concentrations of 50 individual extraterrestrial chromite grains recovered from mid-Ordovician (lower Darriwilian) sediments from the Lynna River section near St. Petersburg, Russia. High concentrations of solar wind-like He and Ne found in most grains indicate that they were delivered to Earth as micrometeoritic dust, while their abundance, stratigraphic position and maj

Specimens of Caloplaca belonging to the group of C. citrina (Hoffm.) Th. Fr. were collected in different localities in the provinces of Buenos Aires (Argentina) and studied using morphology and nrITS data. They were identified as C. austrocitrina Vondrak, Riha, Arup & Sochting, a species newly described from the Black Sea area, but also found in other European countries. These findings are the

The present study focuses on the characteristics of subject-verb agreement in number in spoken and written French, two morphological systems that are very different. In particular, we investigate the impact of frequency of forms and morphological patterns in the input on the acquisition of number agreement in monolingual and bilingual French-speaking children (n=32). Our results demonstrate an alm

Hydroxylated polybrominated diphenyl ethers (OH-PDBEs) are exogenous, bioactive compounds that originate, to a large extent, from anthropogenic activities, although they are also naturally produced in the environment. In the present study nine new authentic OH-PBDE reference standards and their corresponding methyl ether derivatives (MeO-PBDEs) were synthesised and characterised by NMR spectroscop
