DNA in nanochannels-directly visualizing genomic information

The power of nanofluidic channels to analyze DNA is described along with practical experimental hints. As an introduction, a general overview is given on conventional DNA analysis tools, as well as tools under development towards the $1000 genome. The focus of this tutorial review is the stretching of DNA in nanoscale channels for coarse-grained mapping of DNA. To understand the behavior of the DN

Short-range structure of proton-conducting BaM0.10Zr0.90O2.95 (M = Y, In, Sc and Ga) investigated with vibrational spectroscopy

The short-range structures of hydrated and dry samples of the proton-conducting, cubic-structured, acceptor-doped perovskites BaM0.10Zr0.90O2.95 (M=Y, In, Sc and Ga), and, for comparison, BaZrO3, have been investigated using infrared and Raman spectroscopy. The results show that the acceptor-doping leads to local structural distortions of the average cubic structure, most likely related to tilts o

A Surface Temperature Initiated Closure (STIC) for surface energy balance fluxes

The use of Penman-Monteith (PM) equation in thermal remote sensing based surface energy balance modeling is not prevalent due to the unavailability of any direct method to integrate thermal data into the PM equation and due to the lack of physical models expressing the surface (or stomatal) and boundary layer conductances (g(S) and g(B)) as a function of surface temperature. Here we demonstrate a

Networks for the e-society

The 14th edition of International Telecommunications Network Strategy and Planning Symposium (shortly: Networks 2010) held in Warsaw, Poland. Networks 2010 was a four-day professional and scientific event organized by Warsaw University of Technology in co-operation with Polish Association of Telecommunication Engineers (SIT). The conference was focused on network design and planning methods includ

Integrative taxonomy of New World Euplectrus Westwood (Hymenoptera, Eulophidae), with focus on 55 new species from Area de Conservacion Guanacaste, northwestern Costa Rica

90 species of Euplectrus are treated: 55 newly described, all from Area de Conservación Guanacaste (ACG),and 35 previously described species, of which 20 occur in ACG. Three of the previously described species(E. brasiliensis Ashmead, E. hircinus (Say), E. ronnai (Brèthes)) have unknown status, owing to missing or severely damaged type material. The new species, all authored by C. Hansson, are: Eu

Evaluation of seven time-frequency representation algorithms applied to broadband echolocation signals

Time-frequency representation algorithms such as spectrograms have proven to be useful tools in marine biosonar signal analysis. Although there are several different time-frequency representation algorithms designed for different types of signals with various characteristics, it is unclear which algorithms that are best suited for transient signals, like the echolocation signals of echolocating wh

A novel enterovirus and parechovirus multiplex one-step real-time PCR-validation and clinical experience

As the number of new enteroviruses and human parechoviruses seems ever growing, the necessity for updated diagnostics is relevant. We have updated an enterovirus assay and combined it with a previously published assay for human parechovirus resulting in a multiplex one-step RT-PCR assay. The multiplex assay was validated by analysing the sensitivity and specificity of the assay compared to the res

Unwelcome Stranger to the System: Vocational Education in Early Twentieth-Century China

Both in China and internationally, educators and policy makers claim that vocational education and training (VET) is essential for the sound economic development of a country and the physical and social well-being of its population. However, China looks back upon a century-long history of rejection when it comes to popularising VET, despite attempts, both in the present and in the past, to invest

New seeds, gender norms and labor dynamics in Hoima District, Uganda

NERICA, a new group of high-yielding and stress-tolerant upland rice varieties developed by the Africa Rice Center, is changing production strategies of many Ugandan households. This article contributes a better understanding of processes leading to NERICA-related household outcomes in Hoima District, Uganda, by examining patterns of intrahousehold production relations and their consequences for h

Hearing difficulties, uptake, and outcomes of hearing aids in people 85 years of age

Objective: The aim of this study was to investigate self-reported hearing difficulties, uptake, and hearing-aid outcomes and their relationships to demographic, cognitive, psychosocial, and health variables in 85 year olds. Design and study sample: Three hundred and forty-six elderly adults participated in a survey that included questionnaires and home visits. Fifty-five percent of participants ad

Probing Single-Photon Ionization on the Attosecond Time Scale

We study photoionization of argon atoms excited by attosecond pulses using an interferometric measurement technique. We measure the difference in time delays between electrons emitted from the 3s(2) and from the 3p(6) shell, at different excitation energies ranging from 32 to 42 eV. The determination of photoemission time delays requires taking into account the measurement process, involving the i

Lack of steady-state in the global biogeochemical Si cycle: emerging evidence from lake Si sequestration

Weathering of silicate minerals releases dissolved silicate (DSi) to the soil-vegetation system. Accumulation and recycling of this DSi by terrestrial ecosystems creates a pool of reactive Si on the continents that buffers DSi export to the ocean. Human perturbations to the functioning of the buffer have been a recent research focus, yet a common assumption is that the continental Si cycle is at s

Increased plasma levels of the soluble Mer tyrosine kinase receptor in systemic lupus erythematosus relate to disease activity and nephritis

Introduction: Mer and Tyro3 are receptor tyrosine kinases important for the phagocytosis of apoptotic cells. Together with Axl, they constitute the TAM receptor family. These receptors can be shed from the cell membrane and their soluble extracellular regions can be found in plasma. The objective of this study was to elucidate whether the plasma levels of soluble Mer (sMer) and Tyro3 (sTyro3) were

Improved propionic acid production from glycerol: combining cyclic batch-and sequential batch fermentations with optimal nutrient composition

Propionic acid was produced from glycerol using Propionibacterium acidipropionici. In this study, the impact of the concentrations of carbon and nitrogen sources, and of different modes of high cell density fermentations on process kinetics and -efficiency was investigated. Three-way ANOVA analysis and batch cultivations at varying C/N ratios at pH 6.5 revealed that propionic acid production rate

Using multifocal electroretinography hard exudates affect macular function in eyes with diabetic retinopathy

To evaluate the influence of hard exudates on macular function in patients with diabetic retinopathy. METHODS: Thirty seven eyes from 27 diabetic patients, aged 57 +/- 14 years, diabetes duration 12.5 +/- 9 years, not previously treated with photocoagulation, underwent fundus photography, multifocal electroretinography (mfERG) and optical coherence tomography (OCT). Hard exudates were graded from

Not by the Book: The Emergence and Translation of Housing First in Sweden

The emergence of Housing First in Sweden is described and analysed in the light of the deregulation of the housing market and the existing organisation of service delivery for homeless people. The spread and growth of Housing First in Sweden was promoted by Lund University during 2009. Although widely disseminated, implementation of Housing First has been slow. Only seven of Sweden’s 290 municipal

Bridging the accountability gap in hybrid organizations: The case of Malmö-Copenhagen Port

Abstract in UndeterminedPrevious research on hybrid organizations has drawn attention to the accountability gap that is believed to emerge when the provision of public services is transferred to a hybrid organization. In this article we take our point of departure in that research and use a case study method to explore whether this gap can be bridged by existing corporate governance systems or if
