New records of the Paleotropical migrant Hemianax ephippiger in the Caribbean and a review of its status in the Neotropics

Tropical America is currently experiencing the establishment of a new apex insect predator, the Paleotropical dragonfly Hemianax ephippiger (Odonata: Aeshnidae). H. ephippiger is migratory and is suggested to have colonised the eastern Neotropics by chance Trans-Atlantic displacement. We report the discovery of H. ephippiger at three new locations in the Caribbean, the islands of Bonaire, Isla de

Iron-chelated thermoresponsive polymer brushes on bismuth titanate nanosheets for metal affinity separation of phosphoproteins

Separation of phosphoproteins plays an important role for identification of biomarkers in life science. In this work, bismuth titanate supported, iron-chelated thermoresponsive polymer brushes were prepared for selective separation of phosphoproteins. The iron-chelated thermoresponsive polymer brushes were synthesized by surface-initiated atom transfer radical polymerization of N-isopropylacrylami

Human encroachment, climate change and the loss of our archaeological organic cultural heritage : Accelerated bone deterioration at Ageröd, a revisited Scandinavian Mesolithic key-site in despair

Ancient organic remains are essential for the reconstruction of past human lifeways and environments but are only preserved under particular conditions. Recent findings indicate that such conditions are becoming rarer and that archaeological sites with previously good preservation, are deteriorating. To investigate this, we returned to the well-known Swedish Mesolithic site Ageröd I. Here we prese

Antimicrobial Peptides & Leucine Zipper Motif: A legitimate affair in quest of best antibiotic drug

Antimicrobial peptides have emerged as a novel class of therapeutic molecules in recent decades as they exhibit broad-spectrum activity against a variety of Gram-positive, Gram-negative bacteria, fungi and tumor cells. Antimicrobial peptides are nature’s antibiotics that are conserved throughout the evolution. They have an advantage over conventional antibiotics as they target the cell membrane of

Assessment of Global Lung Function Initiative (GLI) reference equations for diffusing capacity in relation to respiratory burden in the Swedish CArdioPulmonary bioImage Study (SCAPIS)

The Global Lung Function Initiative (GLI) has recently published international reference values for diffusing capacity of the lung for carbon monoxide (DLCO). Lower limit of normal (LLN), i.e. the 5th percentile, usually defines impaired DLCO We examined if the GLI LLN for DLCO differs from the LLN in a Swedish population of healthy, never-smoking individuals and how any such differences affect id

Value of pre-construction proof loading information for structural design

We introduce a new concept that enables a decision analyst to explore and quantify the benefits of decision alternatives that exceed the scope of a pre-posterior decision or value of information analysis. This new concept, namely, the expected value of sample information and action analysis, facilitates to examine decision alternatives that become only possible with additional knowledge. The conce

On the value of structural health monitoring

Health monitoring has, over the last 2-3 decades, become a topic of significant interest within the structural engineering research community, but also in the broader areas of civil and mechanical engineering. Whereas the merits of Structural Health Monitoring (SHM) are generally appreciated in qualitative terms there has, as of yet, not been reported much fundamental research on the quantificatio

Challenges and opportunities for cohesive ticketing and traffic information systems in the Greater Copenhagen region

Cross-border regions are characterised by many inherent challenges. Such challenges can include differences in languages, cultures, currencies, markets, labour market conditions, political visions and priorities, governance structures – to name but a few. Greater Copenhagen1 is no different in terms of the challenges it faces as a cross-border region.The aim of this study is to investigate the pos

The knowledge problem of public transport policy

The overall aim of the thesis is to investigate the knowledge problem in regional public transport planning. The knowledge problem is twofold. How do transport policy arrive at the desirable actions they take and how do they assess the alternatives, and what can we say about the contributions of already implemented transport schemes. Paper 1 explores how policy objectives in regional public transp

Structural Diversity of Native Major Ampullate, Minor Ampullate, Cylindriform, and Flagelliform Silk Proteins in Solution

The foundations of silk spinning, the structure, storage, and activation of silk proteins, remain highly debated. By combining solution small-angle neutron and X-ray scattering (SANS and SAXS) alongside circular dichroism (CD), we reveal a shape anisotropy of the four principal native spider silk feedstocks from Nephila edulis. We show that these proteins behave in solution like elongated semiflex

Assessment of terrorism risk mitigation measures for iconic bridges

This paper describes the assessment of the cost efficiency of risk mitigation measures for terrorist attacks with Improvised Explosive Devices (IEDs) for an iconic bridge structure. The assessment is performed with a decision theoretical framework building upon very recent advances in the framework of the COST Action TU1402 on Quantifying the Value of Structural Heath Monitoring. The decision scen

Damage detection and deteriorating structural systems

This paper addresses the quantification of the value of damage detection system and algorithm information on the basis of Value of Information (VoI) analysis to enhance the benefit of damage detection information by providing the basis for its optimization before it is performed and implemented. The approach of the quantification the value of damage detection information builds upon the Bayesian d

Integrating structural health and condition monitoring : A cost benefit analysis for offshore wind energy

There is a large financial incentive to minimise operations and maintenance (O&M) costs for offshore wind power by optimising the maintenance plan. The integration of condition monitoring (CM) and structural health monitoring (SHM) may help realise this. There is limited work on the integration of both CM and SHM for offshore wind power or the use of imperfectly operating monitoring equipment.

Effect of different inspection strategies on the reliability of daniels systems subjected to fatigue

Inspections are an efficient means of enhancing the reliability of redundant structural systems subjected to fatigue.To investigate the effect of such inspections, we represent the deterioration state of a Daniels system by means of a probabilistic fatigue crack growth model of all elements, which considers stochastic dependence among element fatigue behavior. We include inspection results in the

No title

This paper contains recent research results in the field of monitoring supported structural integrity management. The structural integrity management aims at ensuring the functioning of a structure throughout the life cycle by compliance with the target reliabilities. Building upon research results concerning the characteristics of monitoring techniques and data within the framework of reliability

Towards diagnostic metagenomics of Campylobacter in fecal samples

BACKGROUND: The development of diagnostic metagenomics is driven by the need for universal, culture-independent methods for detection and characterization of pathogens to substitute the time-consuming, organism-specific, and often culture-based laboratory procedures for epidemiological source-tracing. Some of the challenges in diagnostic metagenomics are, that it requires a great next-generation s

Ultrastructure and phylogenetic position of Regin rotiferus and Otto terricolus genera et species novae (Bicosoecida, Heterokonta/Stramenopiles)

We describe two novel flagellates isolated from soil, Regin rotiferus and Otto terricolus, genera et species novae, which we cultivated and characterized by light and transmission electron microscopy and by 18S rDNA sequence analysis. Both strains exhibit the key characteristic structural feature of Bicosoecida; i.e. the L-shaped cytostomal root system with an x-fiber, used for feeding. Otto terri

On L1 Attrition and Prosody in Pronominal Anaphora Resolution

This thesis is a collection of four studies on pronominal anaphora resolution with a focus on first language (L1) attrition and prosody. In Study I, we explored the temporariness of attrition effects on anaphora resolution in L1 Italian speakers who moved to Sweden after puberty (i.e., late bilinguals). An experimental group of 20 late Italian-Swedish bilinguals and a control group of 21 Italian m
