Stomatopod crustaceans have the most complex assemblage of visual receptor classes known; retinas of many species are thought to express up to 16 different visual pigments. Physiological studies indicate that stomatopods contain up to six distinct middle-wavelength-sensitive (MWS) photoreceptor classes, suggesting that no more than six different MWS opsin gene copies exist per species. However, we

In 2007, a research program was launched to provide an overview of research needs coupled to arson in Swedish schools. A total of six different Swedish universities and research institutes were involved in different projects in the ensuing research program. These projects involved both technical aspects such as fire detection and fire protection as well as sociological issues related to individual

AIM: Schizophrenia is associated with high cardiovascular mortality predominantly as a result of acute coronary syndrome (ACS). The aim of this study is to analyze time trends of coronary procedures, guideline-based therapy, and all-cause mortality in patients diagnosed with schizophrenia.METHODS AND RESULTS: This Danish nationwide register-based study analyzed 734 patients with a baseline diagnos

Denna avhandling behandlar konstruktionen satsradning. Det avser ett fall av två huvudsatser som följer varandra i samma grafiska mening utan att skiljas av konjunktion, t.ex. och eller men. Satserna kan skiljas av kommatecken men inte av något annat litet skiljetecken som semikolon eller kolon. I avhandlingen undersöks satsradning såväl teoretiskt som empiriskt med utgångspunkt i gymnasieelevers The topic of this thesis is the construction labelled satsradning in Swedish, which typically corresponds to the English term comma splice. They signify a case of two syntactically independent (main) clauses which are joined in the same orthographic sentence, without a coordinating conjunction. The two clauses can either be separated by a comma or joined together with no punctuation mark at all.Th

In this paper we introduce the notion of complex isoparametric functions on Riemannian manifolds. These are then employed to devise a general method for constructing proper r-harmonic functions. We then apply this to construct the first known explicit proper r-harmonic functions on the Lie group semidirect products Rm⋉ Rn and Rm⋉ H 2n+1, where H 2n+1 denotes the classical (2 n+ 1) -dimensional Hei

Vehicle fires in tunnels can have catastrophic consequences for the road users, the property and traffic infrastructure. To support an evacuation planning, this study simulates the fire smoke toxicity and the smoke layer of a vehicle fire in a full-size test tunnel. The three dimensional prediction of the fire smoke toxicity in the test tunnel is realized by implementing the Fractional Effective D

We study left-invariant foliations F on Riemannian Lie groups G generated by a subgroup K. We are interested in such foliations which are conformal and with minimal leaves of codimension two. We classify such foliations F when the subgroup K is one of the important SU(2)*SU(2), SU(2)*SL_2(R), SU(2)*SO(2) or SL_2(R)*SO(2). By this we yield new multi-dimensional families of Lie groups G carrying suc

Objective – Gothenburg University Library has implemented a process with the goal to combine quality assurance and strategic planning activities. The process has bottom-up and top-down features designed to generate strong staff-involvement and long-term strategic stability.Methods – In 2008 the library started implementing a system in which each library team should state a number of improvement ac

Library assessment and external intelligence is important for tracking and improving library activities. Quality assurance and strategic planning are intricate parts in sustainably developing better and more effective services. Gothenburg University Library has implemented a process with the goal to join these activities. The process has both bottom-up and top-down features designed to generate st

A polymer electrolyte fuel cell (PEFC) is an electrochemical device that converts the chemical energy presents in the hydrogen into electricity and heat having as by product only water. The energy conversion process is carried out in a clean and noiseless manner. Depending on the applications, a PEFC works at different operating temperature. In this study, the internal resistance of a PEFC is eval

This article explores walking both as a methodological device, paying close attention to the ethnographer’s own positionality and experiences, and as a form of embodied and emplaced experience of and with heritage sites and urban changes. Walking is an important aspect of how people engage with and experience heritage that draws attention to its emplaced, performative and transformative qualities.

Most signals detected by genome-wide association studies map to non-coding sequence and their tissue-specific effects influence transcriptional regulation. However, key tissues and cell-types required for functional inference are absent from large-scale resources. Here we explore the relationship between genetic variants influencing predisposition to type 2 diabetes (T2D) and related glycemic trai

AbstractSepsis is a clinical condition that develops when the immune system over-response to an infection. Sepsis can lead to organ failure as well as subsequent death. Sepsis-induced host response involves neutrophil over activation which can lead to self tissue damage. Neutrophils are the first line of defence, play a critical role in controlling the infection. Upon activation, neutrophils relea

The physics of quantized vortex excitations in atomic Bose-Einstein condensates has been extensively studied in recent years.Although simple vortex lines are relatively easy to create, control, and measure in experiments, it is a lot more difficult to do the same for vortex ring structures.Here we suggest and explore a method for generating and controlling superfluid vortex rings, vortex ring latt

We study a two component Bose-Einstein condensate in the presence of an inhomogeneous artificial gauge field. In response to this field, the condensate forms a localised vortex lattice structure that leads to a non-trivial symmetry breaking in the phase separated regime. The underlying physical mechanism can be understood by considering the energy landscape and we present a simplified model that i

Growing evidence suggests that sexual reproduction might be common in unicellular organisms, but observations are sparse. Limited knowledge of sexual reproduction constrains understanding of protist ecology. Although Teleaulax amphioxeia and Plagioselmis prolonga are common marine cryptophytes worldwide, and are also important plastid donors for some kleptoplastic ciliates and dinoflagellates, the

This article aims to analyse the changes in migration regimes in Sweden over the period 1739–1982. We have chosen to divide this into four periods where each is characterized as a specific regime: the pre-industrial period (1739–1860), the laissez faire period (1860–1932), the rising ambitions period (1932–1951) and the Rehn-Meidner period (1951–1982). These four periods reveal different approache

Background: Many people are dying from coronavirus disease 2019 (COVID-19), but consensus guidance on palliative care in COVID-19 is lacking. This new life-threatening disease has put healthcare systems under pressure, with the increased need of palliative care provided to many patients by clinicians who have limited prior experience in this field. Therefore, we aimed to make consensus recommendat
