The European shore crab Carcinus maenas is considered to rely on a female pheromone when mating. Evidence, however, is scarce on how the urine pheromone in itself affects males. We investigated male primer and releaser responses to female pheromones with methods that minimized effects from females, delivering female urine either as a pump-generated plume or deposited on a polyurethane sponge. We d
The consultancy industry — broadly defined — has boomed significantly over recent decades. A large and increasing proportion of the welleducated parts of the workforce are employed as management, IT and engineering consultants, communication advisors, etc. Large accounting firms employing hundred of thousands of employees also work with advice-giving on a consultancy (or consultancy-like) basis. S
The marine environment harbors a large proportion of the total biodiversity on this planet, including the majority of the earths’ different phyla and classes. Studying the genomes of marine organisms can bring interesting insights into genome evolution. Today, almost all marine organismal groups are understudied with respect to their genomes. One potential reason is that extraction of high-quality
This paper analyses the use of wonder in the TV-series Cosmos: A Personal Voyage (1980). Popular science has been studied extensively (e.g. Broks 2006; Leane 2007; Perrault 2013), and wonder has been studied moderately (e.g. Daston & Park 1998; Fuller 2006; Vasalou 2015). However, there are very few studies of wonder in popular science. This paper explores how and why wonder is used in Cosmos,
Purpose: Long-term evaluation of the surgical outcome after puberty, particularly patient reported outcome is rare in the literature. The aims of this study were to investigation the patients' satisfaction with the long-term results and their views and memories of their childhood surgery and follow-up. Methods: A modified version of previously used questionnaire was sent to 134 patients ages 18 ye
Aspects of size, structural (im)perfection, inner density, and guest molecule loading capacity of dendronized polymers (DPs) of high generation (6≤g≤8) in aqueous solution are studied using electron paramagnetic resonance spectroscopy on amphiphilic, spin-labeled guest molecules. The results show that the interior of the charged DPs is strongly polar, especially in comparison to their lower genera
This paper investigates how Additive Manufacturing (AM) technologies, as a process innovation, may contribute to a job creation. Further, the various mechanisms in which AM may contribute to an increase in job creation as well as the types of jobs are analyzed. The analysis also goes beyond AM technologies and incorporates other non-technological factors which foster job creation, i.e. higher wage
Cervicogenic or cervical dizziness is debated as an entity. However, there exists both a physiologic basis and a multitude of clinical data to make such a disease concept at least possible and worth considering. In addition, the interaction of proprioceptive and vestibular mechanisms may amplify dizziness of other origin. Cervical pain and dizziness are both common symptoms and may coincide, and n
Oxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C. The stoichiometry of the reaction has been determined: [Tl(H2O)6]3++ SO2(aq)+ 2H2O →[Tl(H2O)6]++ HSO4–+ 3H+. The kinetics has been studied by use of stopped-flow spectrophotometry under pseudo-first-order conditions with eOxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C.

Multi-particle cumulants and corresponding Fourier harmonics are measured for azimuthal angle distributions of charged particles in pp collisions at s = 5.02 and 13 TeV and in p + Pb collisions at sNN = 5.02 TeV, and compared to the results obtained for low-multiplicity Pb+Pb collisions at sNN = 2.76 TeV. These measurements aim to assess the collective nature of particle production. The measuremen
Recent studies find that defection from one's most preferred party to some other party is as common under proportional representation (PR) as it is in plurality systems. It is less elaborated how election-specific contextual factors affect strategic vote choice under PR. This study looks at the impact of two potentially important contextual factors: parties’ coalition signals about cooperation wit
Summer music festivals that involve a few days of camping have often been linked to sustainability agendas. Yet relevant studies have so far overlooked how these events can themselves serve as experiments in less resource consumptive living. Building on a wider interest in the cultural evolution of cleanliness norms, this paper explores how attendees come to use water in personal washing at two UK
The importance of school climate in schooling has been demonstrated consistently over the last 50 years. In this study, we investigate how individual student norms and opinions shape and affect school climate. Through the use of secondary survey data collected within two research projects at eight schools throughout Sweden in two different years, we demonstrate how individual student norms develop
We have studied the reaction of phenylacetylene (PA) with chloro-, bromo-, and iodobenzene on the Au(1 1 1) surface as a model system for the gold-catalysed Sonogashira cross-coupling. Both ultrahigh vacuum-based and ambient pressure x-ray photoelectron spectroscopy show that iodo- and chlorobenzene (IB and CB) undergo the cross-coupling reaction towards diphenylacetylene. Bromobenzene (BB), in co
Objective: intimate partner violence is a significant health problem. Fear of retaliation and shame may prevent women from telling anyone about the violence. This study investigated the prevalence of disclosure and police reporting of intimate partner violence during the first year postpartum. Design: a prospective longitudinal Swedish cohort study based on information from 2563 women who answered
Hydrodynamic cavitation that occurs inside valves not only increases the energy consumption burden of the whole piping system but also leads to severe damages to the valve body and the piping system with a large economic loss. In this paper, in order to reduce the hydrodynamic cavitation inside globe valves, effects of valve body geometrical parameters including bending radius, deviation distance,
This paper is concerned with the manufacturing strategy decision-making structure in multi-plant networks, i.e. how strategic manufacturing decision-making authority is distributed between the network level (i.e. headquarters) and the plant level. We use survey data from 107 manufacturing plants. This research identifies three different structures: centralised at the network headquarter, decentral
Quite recently, the Ioncell-F process, a novel and promising Lyocell fibre process, has been developed. The ionic liquid 1,5-diazabicyclo[4.3.0]non-5-enium acetate ([DBNH]OAc) utilized in this process, was identified as an excellent cellulose solvent for dry-jet wet fibre spinning. Fibres spun from cellulose-[DBNH]OAc solution have shown excellent mechanical properties. Herein, various structural
