Stor variation i grĂŚspollen er en udfordring i vejledningen til allergikere - resultater fra ny dansk pollenforskning "Large variations in grass pollen concentrations are a challenge in the guidance of hayfever patients â new results from Danish researchâ
Pollenallergi rammer op mod en femtedel af Danmarks befolkning og forringer deres hverdag og livskvalitet. Et af de vigtigste vÌrktøjer,en pollenallergiker har, er information om, hvornür der er pollen i luften. Denne information anvender allergikere til at planlÌgge indtag af medicin og tilrettelÌggelse af hverdagen. Süledes kan de begrÌnse deres symptomer sü meget som muligt. En primÌr kilde tilinformation er pollenmülinger fra Viborg og København. Ny forskning fra Aarhus Universitet (AU) og Astma Allergi Danmark afdÌkker, at der er vÌsentlige lokale forskelle I mÌngden af grÌspollen. Denne variation gÌlder isÌr for dage med høje pollental. Resultaterne indikerer, at sÌrligt pü dage med høje pollental for grÌs er nÌrheden til locale kilder meget vigtig. Pü samme tid er de lokale
koncentrationer ikke nødvendigvis korreleret med pollenmülinger fra de nationale mülestationer i Viborg og København.Information om døgnvariationen i pollen er vigtig for pollenallergikerne. De nye studier indikerer store forskelle fra dag til dag, I forhold til hvornür de højeste koncentrationer forekommer, og at dette billede Ìndrer sig
over pollensÌsonen. Viden om døgnvariation, og hvad der styrer den, er endnu langt fra fyldestgørende i forhold til at kunne formidle denne information til pollenallergikere. Vores studier peger i retning af, at de højeste koncentrationer af grÌspollen hyppigst forekommer
tidligt pü aftenen, men at de kan forekomme pü alle tider af døgnet
Seasonal Variation in Diurnal Atmospheric Grass Pollen Concentration Profiles
In this study, the diurnal atmospheric grass pollen concentration profile within the Danish city of Aarhus was
shown to change in a systematic manner as the pollen season
progressed. Although diurnal grass pollen profiles can differ greatly from day-to-day, it is common practice to establish the time of day when peak concentrations are most likely to occur using seasonally averaged diurnal profiles. Atmospheric pollen loads are highly dependent upon emissions, and different species of grass are known to flower and emit pollen at different times of the day and during different periods of the pollen season. Pollen concentrations are also influenced by meteorological factors â directly through those parameters that govern pollen dispersion and transport, and indirectly through the weather-driven flowering process. We found that three different profiles dominated the grass pollen season in Aarhus â a twin peak profile during the early season, a single evening profile during the middle of the season, and a single midday peak during the late season. Whilst this variation could not be explained by meteorological factors,
no inconsistencies were found with the theory that it was driven by a succession of different grass species with different diurnal flowering patterns dominating atmospheric pollen loads as the season progressed. The potential for exposure was found to be significantly greater during the late-season period than during either the early- or mid-season periods
Cosmological Constraints from Galaxy Cluster Velocity Statistics
Future microwave sky surveys will have the sensitivity to detect the
kinematic Sunyaev-Zeldovich signal from moving galaxy clusters, thus providing
a direct measurement of their line-of-sight peculiar velocity. We show that
cluster peculiar velocity statistics applied to foreseeable surveys will put
significant constraints on fundamental cosmological parameters. We consider
three statistical quantities that can be constructed from a cluster peculiar
velocity catalog: the probability density function, the mean pairwise streaming
velocity, and the pairwise velocity dispersion. These quantities are applied to
an envisioned data set which measures line-of-sight cluster velocities with
normal errors of 100 km/s for all clusters with masses larger than
solar masses over a sky area of up to 5000 square degrees. A simple Fisher
matrix analysis of this survey shows that the normalization of the matter power
spectrum and the dark energy equation of state can be constrained to better
than 10 percent, and the Hubble constant and the primordial power spectrum
index can be constrained to a few percent, independent of any other
cosmological observations. We also find that the current constraint on the
power spectrum normalization can be improved by more than a factor of two using
data from a 400 square degree survey and WMAP third-year priors. We also show
how the constraints on cosmological parameters changes if cluster velocities
are measured with normal errors of 300 km/s.Comment: 4 pages, replaced to match accepted version in ApJ Letter. Table 4
shows parameter constraints for normal velocity error of 300 km/s. Reference

Cultural landscapes of tourism in New South Wales and Victoria
The field of cultural landscapes tourism is under-developed in Australia at the level of theory, research and policy development. Yet international research suggests that cultural landscapes tourism has significant potential in attracting new tourists. This research project is a scoping study designed to set out the parameters involved in cultural landscapes tourism research in Australia. It aims to identify how cultural heritage and contemporary cultural diversity impact on visitor experience and on local communities. The objective is to assist the Australian tourism industry particularly those located in regional and rural areas in understanding the growing importance of cultural tourism, by developing a number of case studies of cultural landscapes tourism in two Australia states. These case studies provide examples of existing tourism in a range of different cultural landscape sites, enabling the development of a process by which to identify change in cultural heritage tourism regions, including examining how multicultural precincts can operate as sustainable tourism destinations. Fieldwork with tourists and stakeholders will enable the development of industry strategies to increase tourism in the future. In addition, this fieldwork will facilitate the development of an innovative, multi-disciplinary theory of cultural landscapes tourism. This will set the stage for future research and policy development
Antigenic and genetic characterization of a divergent African virus, Ikoma lyssavirus
In 2009, a novel lyssavirus (subsequently named Ikoma lyssavirus, IKOV) was detected in the brain of an African civet (Civettictis civetta) with clinical rabies in the Serengeti National Park of Tanzania. The degree of nucleotide divergence between the genome of IKOV and those of other lyssaviruses predicted antigenic distinction from, and lack of protection provided by, available rabies vaccines. In addition, the index case was considered likely to be an incidental spillover event, and therefore the true reservoir of IKOV remained to be identified. The advent of sensitive molecular techniques has led to a rapid increase in the discovery of novel viruses. Detecting viral sequence alone, however, only allows for prediction of phenotypic characteristics and not their measurement. In the present study we describe the in vitro and in vivo characterization of IKOV, demonstrating that it is (1) pathogenic by peripheral inoculation in an animal model, (2) antigenically distinct from current rabies vaccine strains and (3) poorly neutralized by sera from humans and animals immunized against rabies. In a laboratory mouse model, no protection was elicited by a licensed rabies vaccine. We also investigated the role of bats as reservoirs of IKOV. We found no evidence for infection among 483 individuals of at least 13 bat species sampled across sites in the Serengeti and Southern Kenya
Gendered accounts of managing diabetes in same-sex relationships:A discursive analysis of partner support
âA question of equality and choiceâ: same-sex couplesâ attitudes towards civil partnership after the introduction of same-sex marriage
Since the introduction of same-sex marriage, there have been two parallel institutions (marriage and civil partnership) for the legal recognition
of same-sex relationships in England, Wales and Scotland. The current study aimed to examine how those in a civil partnership or a same-sex marriage perceive civil partnership in the context of marriage equality. Eighty-two respondents completed a qualitative online survey, and their responses were analysed thematically. The respondents were divided between those who viewed civil partnership as: 1) a stepping stone to equality, and felt that civil partnerships should be discontinued; 2) a form of legal recognition free from cultural baggage, and argued the Government should make civil partnership available for all; or 3) those who displayed ambivalence and conflicting views. We conclude by discussing how the principle of formal equality underpinned opinions on all sides, and what implications this might have for how we understand discrimination
Interpreting and acting upon home blood pressure readings: A qualitative study

We explored how people who have purchased and use a home blood pressure (BP) monitor make sense of, and act upon, readings and how they communicate with their doctor about the practice of home monitoring.
Methods: A qualitative study was designed and participants were purposively recruited from several areas in England, UK. Semi-structured in-depth interviews were conducted with 18 users of home BP monitors. The transcribed data were thematically analysed.
Results: Interpretation of home BP readings is complex, and is often characterised by uncertainty. People seek to assess value normality using ârules of thumbâ, and often aim to identify the potential causes of the readings. This is done by drawing on lay models of BP function and by contextualising the readings to personal circumstances. Based on the perceived causes of the problematic readings, actions are initiated, mostly relating to changes in daily routines. Contacting the doctor was more likely when the problematic readings persisted and could not be easily explained, or when participants did not succeed in regulating their BP through their other interventions. Most users had notified their doctor of the practice of home monitoring, but medical involvement varied, with some participants reporting disinterest or reservations by doctors.
Conclusions: Involvement from doctors can help people overcome difficulties and resolve uncertainties around the interpretation of home readings, and ensure that the rules of thumb are appropriate. Home monitoring can be used to strengthen the patient-clinician relationship
