Drones are increasingly becoming a ubiquitous feature of society. They are being used for a multiplicity of applications for military, leisure, economic, and academic purposes. Their application in academia, especially as social science research tools, has seen a sharp uptake in the last decade. This has been possible due, largely, to significant developments in computerization and miniaturization
Svenska historieböcker är ofta genusomedvetna. Den genushistoria som har skrivits bortser dessutom ofta från andra maktförhållanden som påverkat människors liv och samhället i stort. Den här boken är en genushistoria som handlar om kvinnor och män och om maktrelationerna mellan dem – men också om alla Andra.Det finns etniska Andra, sexuella Andra, kroppsliga Andra och många andra Andra. Gemensamt
En studie av tre rättsfall i Rådhusrätten i Malmö, 1911, 1925 och 1940, där ett stort antal homosexuella män åtalades för "otukt som emot naturen är". Genom en närläsning av rättsfallen går det att återskapa Malmös homosexuella subkultur i stadens geografi och även se förändringar i männens självbild och handlingsmönster.
Serum cystatin C concentration correlates negatively with glomerular filtration rate as well as or better than that of serum creatinine, suggesting a constant formation, and elimination from extracellular fluid mainly by glomerular filtration. It is not known, however, how well the renal plasma clearance of this 13-kDa basic polypeptide matches the glomerular filtration rate. This was investigated
The number of seals in the Baltic Sea has increased dramatically in recent years. While growing seal populations are associated with a thriving marine environment, seals interact with coastal fisheries causing significant damages to catches and gears. One fishery that is severely affected is the coastal cod fishery where the negative impact of seals is believed by many to threaten the existence of
Over 99% of the lead present in blood is usually found in erythrocytes. To investigate the nature of this selective accumulation of lead in erythrocytes, the specific binding of lead to proteins in human erythrocytes was studied using liquid chromatography coupled to inductively coupled plasma mass spectrometry (LC-ICP-MS). The principal lead-binding protein had a mass of approximately 240 kDa, an
Human protein HC is a member of the lipocalin superfamily with unique properties since it carries a covalently bound fluorescent chromophore mediating the linkage of the major part of protein HC to several plasma proteins, with IgA as the dominating complex partner. Native protein HC displays characteristic absorption and fluorescence spectra similar to those of glycated proteins with advanced gly
The effects of human cystatin C on bone resorption, enzyme release, osteoclast generation, bone cell proliferation and bone matrix protein biosynthesis have been examined in different in vitro systems. The effects of cystatin C were compared with those of calcitonin and E 64 (trans-Epoxysuccinyl-L-leucyl-amido-(4-guanidino)butane). Recombinant human cystatin C and E 64 dose dependently inhibited t
We studied the influence of diclofenac on the pharmacokinetics of cloxacillin in healthy volunteers, 60 years or older, as well as the possible effect of cloxacillin and diclofenac on urinary protein excretion. In a randomized, double-blind, cross-over study 15 subjects were given 1 g cloxacillin, and placebo or 75 mg diclofenac, as single intravenous doses. Plasma concentrations of cloxacillin we
We studied renal function during and after surgery in 38 patients undergoing total hip replacement (THR) and 21 patients undergoing total knee replacement (TKR). Serum creatinine and renal excretion of albumin, IgG, protein HC and creatinine were recorded preoperatively and on days 1, 2, 4, and 8, THR patients were randomized to treatment with (n 17) or without (n 21) prophylactic isoxazolyl penic
Recent studies have indicated that serum and plasma cystatin C are better markers for glomerular filtration rate (GFR) than serum creatinine, ubiquitously used for this purpose. To fully exploit the value of serum and plasma cystatin C as GFR markers, reliable age and sex-correlated reference intervals are required. The present study comprised cystatin C determinations in plasma and sera from 259
Data from remote sensing are often used as proxies to quantify biological processes, especially at large geographical scales. The normalized difference vegetation index (NDVI) is the most frequently used proxy for primary productivity. Assuming a direct, positive interrelation between primary and secondary production in terrestrial habitats, NDVI is often used to predict food availability for high
Capsule A combination of several biometric measures enables the reliable sexing of the European Bee-eater Merops apiaster, a species with subtle sex differences in plumage and morphometry. Aims To explore variation in biometrics and their suitability to discriminate sex in adult European Bee-eaters Merops apiaster. Methods We sampled populations of a long-distance migratory species with low sexual
Aim: Knowledge of broad-scale biogeographical patterns of animal migration is important for understanding ecological drivers of migratory behaviours. Here, we present a flyway-scale assessment of the spatial structure and seasonal dynamics of the Afro-Palaearctic bird migration system and explore how phenology of the environment guides long-distance migration. Location: Europe and Africa. Time per
Across their ranges, different populations of migratory species often use separate routes to migrate between breeding and non-breeding grounds. Recent changes in climate and land-use have led to breeding range expansions in many species but it is unclear whether these populations also establish new migratory routes, non-breeding sites and migration phenology. Thus, we compared the migration patter
The stability of albumin, protein HC, immunoglobulin G, κ- and λ-chain immunoreactivity, orosomucoid and α1 -antitrypsin in urine stored at -20°C for up to 24 months was investigated. Significant decreases of the median concentration values for protein HC, IgG and α1-antitrypsin were observed for native urine. Addition to urine of a preservative solution containing benzamidinium chloride, EDTA, tr
Currently, the deployment of tracking devices is one of the most frequently used approaches to study movement ecology of birds. Recent miniaturization of light-level geolocators enabled studying small bird species whose migratory patterns were widely unknown. However, geolocators may reduce vital rates in tagged birds and may bias obtained movement data. There is a need for a thorough assessment o
It is well established that the nutrient and energy requirements of birds increase substantially during moult, but it is not known if these increased demands affect their aerobic capacity. We quantified the absolute aerobic scope of house and Spanish sparrows, Passer domesticus and P. hispaniolensis, respectively, before and during sequential stages of their moult period. The absolute aerobic scop
In many taxa, the most common form of sex-biased migration timing is protandry—the earlier arrival of males at breeding areas. Here we test this concept across the annual cycle of long-distance migratory birds. Using more than 350 migration tracks of small-bodied trans-Saharan migrants, we quantify differences in male and female migration schedules and test for proximate determinants of sex-specif
