Feather mites and internal parasites in small ground finches (geospiza fuliginosa, emberizidae) from the galapagos Islands (Equador)

During a parasite survey, we collected data on the presence and distribution of feather mites, intestinal parasites, and blood parasites of small ground finches (Geospiza fuliginosa) from 4 islands in the Galapagos. We recorded 4 species of feather mites, with the most common species, Trouessartia geospiza, present on the majority (77% 308/400) of individuals. Birds with high loads of T. geospiza

Pathways to Urban Sustainability : How Science Can Contribute to Sustainable Development in Cities

Pressing sustainability challenges reinvigorate calls for scientific actors to strengthen their profile as change agents. Focusing on the urban context, we point to four forms of science-policy-society interactions as key pathways to advance the sustainability transformation in cities.Recent years have seen a considerable broadening of the ambitions in urban sustainability policy-making. With its

Exploring alternative economic pathways : a comparison of foundational economy and Doughnut economics

A number of intersecting crises are currently ongoing at multiple scales, including increasing inequality, environmental degradation, and climate destabilization, as well as new surges of populism and mounting public health threats. These emergencies question our economic model of past decades and provoke a rethinking of the general approach to economic policy from a multi-scalar perspective. In t

Rosiglitazone treatment enhances intracellular actin dynamics and glucose transport in hypertrophic adipocytes

Aims: To accommodate surplus energy, adipose tissue expands by increasing both adipose cell size (hypertrophy) and cell number (hyperplasia). Enlarged, hypertrophic adipocytes are known to have reduced insulin response and impaired glucose transport, which negatively influence whole-body glucose homeostasis. Rosiglitazone is a peroxisome proliferator-activated receptor gamma (PPARγ) agonist, known

The development of the experience curve concept and its application in energy policy assessment

This paper presents some of the results of the project, EXTOOL, Experience Curves: A Tool for Energy Policy Programmes Assessment, funded by the European Commission. The objective of the project was to analyse the experience curve as a tool for the assessment of energy policy measures. This is of special interest, since the use of experience curves for the assessment of energy policy measures requ

The significance of trying : How organizational members meet the ambiguities of diversity

Abstract We address the uncertain outcomes of diversity work in organizations by showing that diversity management does not let itself be reduced to a matter of success and failure. Drawing upon theories of ambiguities in organizations and 2.5 years of longitudinal fieldwork in a Swedish municipality, we show that ambiguities characterize diversity work, including what diversity encompasses, the g

Developing general guidelines and tools for documenting merits from external engagement - A practical approach

The Swedish higher education sector is in a phase in which the importance of external engagement for quality in research and education at universities has gradually become clearer. This development is also visible at European as well as global level. It is therefore relevant to assess and value the work that takes place at universities within the framework of external engagement and to support a d

Creaky voice in South Swedish accent 1

Pitch and voice quality are increasingly understood as closelyintertwined. While Swedish and Norwegian word accents have traditionally been understood in terms of pitch, Danish stød, which is systematically related when it comes to distribution and function, has been described as a type of creaky voice. According to the Laryngeal Articulator Model (LAM), both pitch lowering and creaky or harsh voi

Scheimpflug lidar range profiling of bee activity patterns and spatial distributions

Background: Recent declines of honeybees and simplifications of wild bee communities, at least partly attributed to changes of agricultural landscapes, have worried both the public and the scientific community. To understand how wild and managed bees respond to landscape structure it is essential to investigate their spatial use of foraging habitats. However, such studies are challenging since the

Analysis of the New Moon Times on the Disk of the Astronomical Clock in Gdansk, Poland.

The calendar disk of the fifteenth century astronomical clock in the church of Saint Mary in Gdansk (Poland) contains a wealth of astronomical and calendrical data. We make a statistical analysis of the mean conjunction times of all the mean New Moons as represented on the disk for four Metonic 19-year cycles. We find that the conjunction times were generated using the Alfonsine value for the leng

Safinamide in the treatment pathway of Parkinson’s Disease : a European Delphi Consensus

Safinamide is a highly selective, reversible MAO B-inhibitor recently marketed in European and North American countries. To better define clinical indications regarding motor and non-motor symptoms, targeted population and safety of this compound, ten movement disorders specialists, experts in their field, convened and developed a panel of statements on: the role of glutamate in Parkinson’s diseas

Short-term effects of postural taping on pain and forward head posture : a randomized controlled trial

Background: Balance Body Tape (BBT) is a recently developed taping-method with the aim to reduce pain and improve posture through change in movement behavior. However, the potential effects of a treatment with BBT are scarcely documented. Therefore, the aim with this study was to investigate the effect of a three-week Balance body tape-treatment on the intensity of perceived neck, shoulder and bac

Conformal minimal foliations on semi-Riemannian Lie groups

We study left-invariant foliations F on semi-Riemannian Lie groups G generated by a subgroup K. We are interested in such foliations which are conformal and with minimal leaves of codimension two. We classify such foliations F when the subgroup K is one of the important groups SU(2), SL_2(R), SU(2)*SU(2), SU(2)*SL_2(R)$, SU(2)*SO(2), SL_2(R)*SO(2). This way we construct new multi-dimensional famil

Ketamine inhibits TNF-α-induced cecal damage by enhancing RIP1 ubiquitination to attenuate lethal SIRS

Systemic inflammatory response syndrome (SIRS) is a sepsis-associated inflammatory state and a self-defense mechanism against specific and nonspecific stimuli. Ketamine influences many key processes that are altered during sepsis. However, the underlying mechanisms remain incompletely understood. In this study, TNF-α-treated mice, as well as HT-29 and L929 cell models, were applied to characterize

Exploring Climate Change Perspectives. An Analysis of Undergraduate Students' Place-Based Attachment in Appalachia, USA

Despite global scientific consensus, climate change is a highly controversial and politicized issue in the United States. Grounded in two quantitative survey iterations with approximately 446 responses, 28 semi-structured interviews, and 4 focus groups with 60 undergraduate students from six state universities in the Appalachian region, this five-year study explores the role of place-based attachm

Maximum detection distances for gamma emitting point sources in mobile gamma spectrometry

In this study an algorithm was developed for calculating maximum detectable distance (MDD) for mobile gamma-ray detection of lost sources in-situ for some common mobile spectrometer systems and gamma sources (137Cs and 60Co). The MDD is a function of detector efficiency, vehicle speed, acquisition time interval, radiation background level and accepted frequency of false alarms. To test its accurac
