Stomatopod crustaceans possess apposition compound eyes that contain more photoreceptor types than any other animal described. While the anatomy and physiology of this complexity have been studied for more than two decades, few studies have investigated the molecular aspects underlying the stomatopod visual complexity. Based on previous studies of the structure and function of the different types
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
