The pollen grains of ragweed are important aeroallergens that have the potential to be transported long distances through the air. The arrival of ragweed pollen in Nordic countries from the Pannonian Plain can occur when certain conditions are met, which this study aims to describe for the first time. Atmospheric ragweed pollen concentrations were collected at 16 pollen-monitoring sites. Other fac
Servicizing is a business model that holds the potential to support a shift towards more sustainable production and consumption by selling to the consumer the product's function, rather than the material product itself. This can offer direct environmental benefits by reducing the material and energy intensity of market transactions. Servicizing based business offers are starting emerging on the ma
Vehicular communication channels are characterized by a non-stationary time- and frequency-selective fading process due to fast changes in the environment. We characterize the distribution of the envelope of the first delay bin in vehicle-to-vehicle channels by means of its Rician $K$-factor. We analyze the time–frequency variability of this channel parameter using vehicular channel measurements a
Boken är ett resultat av tre symposier ordnade av Centrum för Europaforskning vid LU och NGO ” Citizens without Boundaries”, Syftet med symposierna var att inbjuda forskare och allmänheten till diskussion om det kollektiva minnets praktiker med fokus på hur de påverkar vår förmåga att kritiskt förhålla oss till historiska fakta och vårt sätt att se på den Andre. Under det första symposiet avhandl
Background: Baker's yeast (Saccharomyces cerevisiae) has been engineered for xylose utilization to enable production of fuel ethanol from lignocellulose raw material. One unresolved challenge is that S. cerevisiae lacks a dedicated transport system for pentose sugars, which means that xylose is transported by non-specific Hxt transporters with comparatively low transport rate and affinity for xylo
This letter reports the capacity performance of a handheld dual-band dual-antenna compact MIMO terminal, which utilizes uncoupled adaptive impedance matching for capacity maximisation. The capacity is evaluated at 0.825 GHz and 2.35 GHz in an indoor office environment. The results show that adaptive matching enhances capacity by up to 44% and 22% at the low and high frequency bands, respectively,
Prophylaxis and treatment with antiretroviral drugs and elective caesarean section delivery have resulted in very low mother-to-child transmission of HIV during recent years. Updated general treatment guidelines and increasing knowledge about mother-to-child transmission have necessitated regular revisions of the recommendations for the prophylaxis and treatment of HIV-1 infection in pregnancy. Th
Liquid-liquid phase separation occurs in young mammalian eye lenses and in concentrated solutions of isolated eye lens proteins, and has been linked to some forms of cataract. Here we study theoretically the protein compositions and cloud temperatures of two separated equilibrium phases that form out of concentrated mixtures of model proteins, chosen to have properties similar to those which repro
Spruce bark beetle outbreaks are common in Norway spruce forests following windstorm damage, due to ample availability of brood material. The realization of an outbreak depends on factors regulating the Ips typographus population dynamics, such as weather conditions and salvage cutting. In this study, we take an ecosystem modelling approach to analyse the influence of multiple environmental factor
The properties of gas-borne aggregates are important in nano-technology and for potential health effects. Gold aggregates from three generators (one commercial and one custom built spark discharge generator and one high-temperature furnace) have been characterized. The aggregate surface areas were determined using five approaches - based on aggregation theory and/or measured aggregate properties.
Barnahus är en ny modell för samverkan mellan myndigheter kring som utsatts för brott. Tanken är att barnen ska bli omhändertagna i en barnvänlig miljö där alla nödvändiga utredningar kan genomföras. Socialtjänsten är en av de berörda myndigheterna, och har ett särskilt ansvar för att dessa barn får det skydd eller stöd de behöver. I denna bok undersöks och jämförs socialtjänstens utredningar om
Abstract in Undeterminednew fit is done to obtain numerical values for the order p(4) low-energy-constants L(i)(r) in Chiral Perturbation Theory. This includes both new data and new calculated observables. We take into account masses, decay constants, K(l4), pi pi and pi K scattering lengths and slopes and the slope of the pion scalar formfactor. We compare in detail where the changes w.r.t. the 1
In three experiments, participants rated how well a number of adjectives described their in-group (e.g. kind-hearted, helpful, intelligent, efficient, etc.). In Experiment 1, females were found to rate their ingroup (females) more favorably when reporting verbally to female (rather than male) experimenters. This finding was further explored in two subsequent experiments where response format (writ
Traceability of dairy products is an important issue for the dairy industry. Empirical studies have demonstrated the utility of stable isotope measurements on milk for verification of origin. However, various drivers influence the isotopic composition of a food stuff, such as rainfall levels or food supplements. Relationships between the isotopic composition (δ2H, δ18O, δ13C and δ15N) of milk fatt
The aim of this article is to propose a method for creating a more coherent concept of norms – and to deliver a tentative and open suggestion on how to define norms in a way that might fit into the context of Sociology of Law (further on shortened, SoL). The idea is that the norm concept can be chiselled out through ontological analysis, and that this analysis can be conducted in a way that allow
