Groin pain and soccer players: male versus female occurrence.

Groin pain is common in soccer players. Comparison of results from different studies, especially between genders, is difficult as studies use different definitions and data collection procedures. Therefore we conducted a study of both male and female soccer players enabling direct gender comparison.

Effects of Nesting Cormorants (Phalacrocorax carbo) on Soil Chemistry, Microbial Communities and Soil Fauna

Seabirds act as vectors transporting marine nutrients to land by feeding on fish while nesting and roosting on islands. By depositing large amounts of nutrient-rich guano on their nesting islands they strongly affect island soils, vegetation and consumers. However, few studies have investigated how nesting seabirds affect soil communities. In this study, we investigated how cormorant nesting colon

Waiting Places as Temporal Interstices and Agents of Change

One of the main ways in which in-between time-spaces are organised and materialised in the urban environment is through waiting places. In his article we point to the transformative potential of waiting places, their role as actors in an urban web, and discuss briefly their societal role in recent historical changes. Public waiting places are today increasingly becoming pre-programmed: connected t

Dietary switching of collembola in grassland soil food webs

Soil food webs are characterised by complex direct and indirect effects among the organisms. Consumption of microorganisms by soil animals is considered as an important factor that contributes to the stability of communities, though cascading effects within the food web can be difficult to detect. In a greenhouse experiment, an addition of a high number the fungal feeding collembola Folsomia quadr

The Swedish Version Of The Parent-Rated Junior Temperament And Character Inventory (J-Tci)

To evaluate the psychometric characteristics of the Swedish version of the Junior Temperament and Character Inventory (J-TCI), it was sent to parents of 9- and 12-yr-old twins in Sweden. The final number of responders was 196 parents who rated 92 female and 104 male twin pairs. The inventory of one twin, randomly chosen from each pair, was included in the analyses. Reward Dependence, Persistence,

Performance of methanol kinetic mechanisms at oxy-fuel conditions

Methanol premixed flames were studied under oxy-fuel conditions for the first time. Laminar burning velocities were measured with the heat flux method at atmospheric pressure for unburnt gas temperatures of 308-358 K within a stoichiometric range of phi = 0.8-1.5. A linear relationship between temperature and laminar burning velocity on a log-log scale was observed. The experimental results are di

Trivacancy-oxygen complex in silicon: Local vibrational mode characterization

FTIR study of the evolution of multivacancy-oxygen-related defects in the temperature range 100-350 degrees C in Czochralski-grown Si samples irradiated with different particles (10 MeV electrons and 5 MeV neutrons) has been carried out. Appearance of two absorption bands positioned at 833.4 and 842.4 cm(-1) has been found upon annealing of the divacancy related absorption band at 2767 cm(-1). The

Measuring and modeling the oxygen profile in a nitrifying Moving Bed Biofilm Reactor

In this paper we determine the oxygen profile in a biofilm on suspended carriers in two ways: firstly by microelectrode measurements and secondly by a simple mathematical model. The Moving Bed Biofilm Reactor is well-established for wastewater treatment where bacteria grow as a biofilm on the protective surfaces of suspended carriers. The flat shaped BiofilmChip P was developed to allow good condi

Interviewees with an agenda – Learning from a 'failed' interview

Social constructionists consider interviews as mutually co-constructing meaning. But what if the interlocutors do not seem to agree on what they construct? What if the interviewee has a particularly strong agenda, far from the intended research topic? Are these ‘failed’ interviews? We address this issue using a ‘deviant’ interview in a study of ‘being a neighbour’. First, we add to the discussion

Temporal dynamics of bird community composition: an analysis of baseline conditions from long-term data

Numerous anthropogenic activities threaten the biodiversity found on earth. Because all ecological communities constantly experience temporal turnover due to natural processes, it is important to distinguish between change due to anthropogenic impact and the underlying natural rate of change. In this study, we used data sets on breeding bird communities that covered at least 20 consecutive years,

Water and Sewage South (VA SYD) - Governance versus Ownership in Jointly Owned Local Government Organisations

This is a paper about ownership and governance in a jointly owned local government organization providing water services (Water and Se wage South). The paper discusses the conditions for governance and ownership influence in a jointly owned local government organisation. Extra attention is directed to the issues concerned with merging existing municipal organisations, previously acting solely with

Lectotypifications of names of Hieracium (Asteraceae) based on material from the Swedish provinces Gastrikland, Halsingland and Medelpad

Lectotypes are designated for 83 names of species of Hieracium sect. Hieracium, H, sect. Vulgata and H. sect. Bifida described by Swedish authors based on material from the provinces Gastrikland, Halsingland and Medelpad of central Sweden. Whenever needed, the affinities and taxonomic value of the lectotypified taxa and the taxonomic implications of the lectotypifications are discussed. One new co

Commodifying Danish housing commons

Housing was a backbone of the Danish welfare state, but this has been profoundly challenged by the past decades of neoliberal housing politics. In this article we outline the rise of the Danish model of association-based housing on the edge of the market economy (and the state). From this, we demonstrate how homes in private cooperatives through political interventions in the context of a booming

Derivation-Invariant Subspaces of C∞

Let $C^\infty(a,b)$ be the Fr\'echet space of all complex-valued infinitely differentiable functions on a (finite or infinite) interval $(a,b)\subset\mathbb{R}$. Let ${L\subset C^\infty(a,b)}$ be a closed subspace such that $DL\subset L$, where $D=\frac{d}{dx}$. Then the spectrum $\sigma_L$ of $D$ on $L$ is either the whole complex plane, or a discrete possibly void set of eigenvalues $\lambda$, e
