Paleolimnological records of regime shifts in lakes in response to climate change and anthropogenic activities
Regime shifts in lake ecosystems can occur in response to both abrupt and continuous climate change, and the imprints they leave in paleolimnological records allow us to investigate and better understand patterns and processes governing ecological changes on geological time scales. This synthesis investigates paleolimnological records that display apparent regime shifts and characterizes the shift
Vem tycker om hen?
Swedish is the first language that has a gender-neutral third-person singular pronoun, hen, that has spread from transgender and queer communities to the broader society and now exists in parallel with the two traditional gendered pronouns representing ‘she’ and ‘he’. Many strong emotions have arisen during this process, both for and against hen. This study aims at analyzing what background factor
Two thirds of Survey Respondents in Southern Sweden used Complementary or Alternative Medicine (CAM) in 2015
The impact of CEO long-term equity-based compensation incentives on economic growth in collectivist versus individualist countries
This study examines the impact of the prevalence of long-term equity-based chief executive officer (CEO) compensation incentives on GDP growth, and we address the moderating role of individualist versus collectivist cultures on this relationship. We argue that long-term incentives given to CEOs in some firms may convey to other CEOs that they too may be able to receive such incentives and rewards
A to Z of the muon anomalous magnetic moment in the MSSM with Pati-Salam at the GUT scale
We analyse the low energy predictions of the minimal supersymmetric standard model (MSSM) arising from a GUT scale Pati-Salam gauge group further constrained by an A4 × Z5 family symmetry, resulting in four soft scalar masses at the GUT scale: one left-handed soft mass m0 and three right-handed soft masses m1, m2, m3, one for each generation. We demonstrate that this model, which was initially dev
Wavelength-independent constant period spin-echo modulated small angle neutron scattering
Spin-Echo Modulated Small Angle Neutron Scattering (SEMSANS) in Time-of-Flight (ToF) mode has been shown to be a promising technique for measuring (very) small angle neutron scattering (SANS) signals and performing quantitative Dark-Field Imaging (DFI), i.e., SANS with 2D spatial resolution. However, the wavelength dependence of the modulation period in the ToF spin-echo mode has so far limited th
Reactivity of dissolved organic matter in response to acid deposition
Fluvial export of organic matter from the terrestrial catchment to the aquatic system is a large and increasing carbon flux. The successful reduction in sulfuric acid deposition since the 1980s has been shown to enhance the mobility of organic matter in the soil, with more terrestrially derived dissolved organic matter (DOM) reaching aquatic systems. Changes in soil acidity also affect the quality

Syntheses, characterization and catalytic activities of CaAl-layered double hydroxide intercalated Fe(III)-amino acid complexes
Synthesis of intercalated composites were carried out using CaAl-LDH (layered double hydroxide) as host and the anionic form of Fe(III)-amino acid complexes as guest materials. Intercalation was attempted with two methods either introducing the preformed complexes or constructing the complex among the layers of the LDH. After optimization of the synthesis parameters, structural characterization wa
Generic technique to grow III-V semiconductor nanowires in a closed glass vessel
Crystalline III-V semiconductor nanowires have great potential in fabrication of nanodevices for applications in nanoelectronics and optoelectronics, and for studies of novel physical phenomena. Sophisticated epitaxy techniques with precisely controlled growth conditions are often used to prepare high quality III-V nanowires. The growth process and cost of these experiments are therefore dedicated
Promoting innovation through a virtual incubator model : The Water Innovation Accelerator (WIN)
In this study we explore and analyse a virtual network-centred incubator model called the Water Innovation Accelerator (WIN). The incubator model has been designed and implemented in Sweden to enable and orchestrate water-related innovative solutions by connecting different players via organized networks. Framed by theory and research on open innovation, incubation models, and entrepreneurial netw

Neck support pillows : a comparative study
BACKGROUND: Special neck support pillows claiming to improve rest and reduce neck pain are currently being advertised.OBJECTIVE: To test whether neck pillows have any positive effect on neck pain and quality of sleep compared with usual pillows and, if so, to find the optimal characteristics of such a pillow.METHODS: Thirty-seven hospital employees and 18 neck patients were asked to test six neck
Direct Conversion of Fibroblasts to Megakaryocyte Progenitors
Current sources of platelets for transfusion are insufficient and associated with risk of alloimmunization and blood-borne infection. These limitations could be addressed by the generation of autologous megakaryocytes (MKs) derived in vitro from somatic cells with the ability to engraft and differentiate in vivo. Here, we show that overexpression of a defined set of six transcription factors effic

Sex differences in immune responses : Hormonal effects, antagonistic selection, and evolutionary consequences
Males and females differ in both parasite load and the strength of immune responses and these effects have been verified in humans and other vertebrates. Sex hormones act as important modulators of immune responses; the male sex hormone testosterone is generally immunosuppressive while the female sex hormone estrogen tends to be immunoenhancing. Different sets of T-helper cells (Th) have important
Membrane process opportunities and challenges in the bioethanol industry
Increasing oil prices and growing environmental concerns in recent years have driven the development of renewable biofuels. Until now, most of the bioethanol production concepts are based on sugar and starch crops as feedstock, while research on second generation of bioethanol concepts is investigating the use of cellulosic biomass such as straw, wood, etc. as feedstock. The first part of the pape
Hydrophobic pervaporation for environmental applications : Process optimization and integration
The focus of this paper is on the design of pervaporation units for wastewater treatment taking into account technical, economic, and environmental aspects. Two different sized industrial wastewater streams of water-chloroform, and of water-methyl-isobutylketone (MIBK) are considered. Based on a wastewater stream of 1,500 kg/d, a semi-batch process combining pervaporation with a decanter recycle l
