A DNA barcode-based survey of terrestrial arthropods in the Society Islands of French Polynesia : Host diversity within the SymbioCode project

We report here on the taxonomic and molecular diversity of 10 929 terrestrial arthropod specimens, collected on four islands of the Society Archipelago, French Polynesia. The survey was part of the ‘SymbioCode Project’ that aims to establish the Society Islands as a natural laboratory in which to investigate the flux of bacterial symbionts (e.g., Wolbachia) and other genetic material among branche

A novel derivative of the fungal antimicrobial peptide plectasin is active against Mycobacterium tuberculosis

Tuberculosis has been reaffirmed as the infectious disease causing most deaths in the world. Co-infection with HIV and the increase in multi-drug resistant Mycobacterium tuberculosis strains complicate treatment and increases mortality rates, making the development of new drugs an urgent priority. In this study we have identified a promising candidate by screening antimicrobial peptides for their

Investigations of alkaline and enzymatic membrane cleaning of ultrafiltration membranes fouled by thermomechanical pulping process water

The pulp and paper industry is one of the most important industrial sectors worldwide, and has considerable potential for the sustainable fractionation of lignocellulosic biomass to provide valuable compounds. Ultrafiltration (UF) is a suitable separation technique for the profitable production of hemicelluloses from process water from thermomechanical pulping (ThMP), but is limited by membrane fo

Nya och gamla näckrosor i svenska vatten

The occurence of introduced and native species and hybrid cultivars of Nuphar and Nymphaea in Sweden is discussed and a preliminary diagnostic key is presented. Swedish occurences of escaped Nuphar advena, Nymphaea ×marliacea, N. ×thiona and N. ×laydekeri are reported for the first time.

Pulseless electrical activity is associated with improved survival in out-of-hospital cardiac arrest with initial non-shockable rhythm

Objective: To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm. Methods: The Swedish Registry of Cardiopulmonary Resuscitation is a prospectively recorded nationwide registry of modified Utstein param

Collection of microlevel Safety and efficiency Indicators with Automated Video Analysis

This paper revises the theoretical grounds for relation of the micro-level behaviour indicators to the safety and efficiency (level-of service) of the local traffic system. Automated video analysis is suggested as a tool for collection of the individual data about road users driving trajectories and speeds and interaction with other road users. The authors describe the current state of the video a

Fundamental bounds on extraordinary transmission with experimental validation

This paper presents a study of extraordinary transmission (EoT) through arrays of sub-wavelength apertures. Fundamental limitations for this phenomenon are formulated as a sum rule, relating the transmission coefficient over a bandwidth to the static polarizability. The sum rule is rigorously derived for arbitrary periodic apertures in thin screens. By this sum rule we establish a physical bound o

Asars och Karlars ättling

Behandlar den klassiska och fornnordiska mytologin i konsten, vilka användes i utformandet av Röda salongen på Rosendal för att skapa en apoteos av Karl XIV Johan.

Iceland should replace its central bank with a currency board

Since its independence in 1918, Iceland has tried a number of monetary regimes. They have all failed to provide monetary stability. Iceland is too small to conduct an independent monetary policy. What should Iceland do? We arrive at the conclusion that a currency board with the euro as the reserve currency is the best choice. A currency board delivers monetary stability through exchange rate stabiSince its independence in 1918, Iceland has tried a number of monetary regimes.

Lung bioengineering : advances and challenges in lung decellularization and recellularization

PURPOSE OF REVIEW: Bioengineering the lung based on its natural extracellular matrix (ECM) offers novel opportunities to overcome the shortage of donors, to reduce chronic allograft rejections, and to improve the median survival rate of transplanted patients. During the last decade, lung tissue engineering has advanced rapidly to combine scaffolds, cells, and biologically active molecules into fun

Characteristics of healthy vascular ageing in pooled population-based cohort studies : the global Metabolic syndrome and Artery REsearch Consortium

OBJECTIVE: Arterial ageing is characterized by increasing arterial stiffness as measured by pulse wave velocity (PWV). This process is enhanced in participants with early vascular ageing (EVA), but slowed in participants with healthy vascular ageing (HVA). We aimed to describe characteristics of EVA and HVA in a transcontinental study including 11 cohorts.METHODS: In all, 18 490 participants from

The Environmental Determinants of Diabetes in the Young (TEDDY) Study: 2018 Update

Purpose of Review: The environmental triggers of islet autoimmunity leading to type 1 diabetes (T1D) need to be elucidated to inform primary prevention. The Environmental Determinants of Diabetes in the Young (TEDDY) Study follows from birth 8676 children with T1D risk HLA-DR-DQ genotypes in the USA, Finland, Germany, and Sweden. Most study participants (89%) have no first-degree relative with T1D

Multiple Late Holocene surges of a High-Arctic tidewater glacier system in Svalbard

Most large tidewater glaciers in Svalbard are known to have surged at least once in the last few hundred years. However, very little information exists on the frequency, timing or magnitude of surges prior to the Little Ice Age (LIA) maximum in ∼1900. We investigate the sediment-landform assemblages produced by multiple advances of the Nathorstbreen glacier system (NGS) in order to reconstruct its

Longitudinal monoaminergic PET imaging of chronic proteasome inhibition in minipigs

Impairment of the ubiquitin proteasome system has been implicated in Parkinson’s disease. We used positron emission tomography to investigate longitudinal effects of chronic intracerebroventricular exposure to the proteasome inhibitor lactacystin on monoaminergic projections and neuroinflammation. Göttingen minipigs were implanted in the cisterna magna with a catheter connected to a subcutaneous i

Ballistic tracks in graphene nanoribbons

High quality graphene nanoribbons epitaxially grown on the sidewalls of silicon carbide (SiC) mesa structures stand as key building blocks for graphene-based nanoelectronics. Such ribbons display 1D single-channel ballistic transport at room temperature with exceptionally long mean free paths. Here, using spatially-resolved two-point probe (2PP) measurements, we selectively access and directly ima
