The accumulation of studies delimiting species in Amazonia has not only shed light on the patterns of its outstanding species richness but also allowed a better understanding of the processes of diversification within this immense region. Nevertheless, vast knowledge gaps remain even for prominent anuran species complexes, such as the Rhinella margaritifera species group. This clade of toads compr

Background: Low- and middle-income countries have committed to achieving universal health coverage (UHC) as a means to enhance access to services and improve financial protection. One of the key health financing reforms to achieve UHC is the introduction or expansion of health insurance to enhance access to basic health services, including maternal and reproductive health care. However, there is a

The Parkinson’s Disease Questionnaire – 39 is the most widely used disease-specific health status questionnaire for Parkinson’s disease. Evaluations of various language versions have focused on psychometric properties, whereas documented evaluations regarding linguistic validity, respondent burden and questionnaire content are largely lacking. Work with the Swedish Parkinson’s Disease Questionnair

We study the evolution and renegotiation of the cash-flow rights that venture capitalists (VCs) obtain in their portfolio companies. When company performance between financing rounds is poor, subsequent contracts contain stronger VC cash-flow rights, and existing VCs tend to either give new VCs senior claims or forfeit their existing rights altogether. These results are consistent with the importa

In this anthology are gathered 28 essays, devoted to the interrelations of the arts and media. They present together the current state of the emerging field of Interart Studies. The contributors – Stephen Greenblatt, Claus Clüver, Erika Fischer-Lichte, John Neubauer, Steven Paul Scher, Walter Bernhart, Ulrich Weisstein, Eric Haskell, Eric Vos, Thomas Elsaesser, among others – are leading internati

Meteor radar observations carried out in August-September 1953-84 at theOnsala Space Observatory in Sweden show long-term, as well as short termvariations in meteor radar rates. These rate variations are associatedwith position in the solar cycle, and with variations in the solar windsector structure. An inverse correlation is found between meteor radarrates and the solar cycle. The magnitude of t

The paper deals with the ways an advanced digital technology like GPS (Global Positioning System) is integrated with the mundane practices of wayfinding and moving on foot. I will use N Katherine Hayles take on the concept cognisphere: ”The cognisphere gives a name and shape to the globally interconnected cognitive systems in which humans are increasingly embedded.” The concept deals with the ways

Self-incompatibility (SI) in the Brassicaceae plant family is controlled by the SRK and SCR genes situated at the S locus. A large number of S haplotypes have been identified, mainly in cultivated species of the Brassica and Raphanus genera, but recently also in wild Arabidopsis species. Here, we used DNA sequences from the SRK and SCR genes of the wild Brassica species B. cretica, together with p

Popular Abstract in Swedish Den huvudsakliga hämmande signalsubstansen i hjärnan är GABA (gamma-aminobutyric acid, gamma-aminosmörsyra). GABA finns i ungefär hälften av alla nervceller i hjärnan och alla nervceller i hjärnan antas ha receptorer som binder GABA. Om man tänker på alla de normala neurologiska funktioner samt rubbningar där GABA är involverat är det inte svårt att förstå GABA:s oerhörInhibitory neurotransmission in the brain is mostly mediated by gamma-aminobutyric acid type A (GABAA) receptors. These receptors are involved in both phasic inhibition (point-to-point inhibition, synaptic transmission) and tonic inhibition (diffuse form of inhibition, brain homeostasis). In this thesis the functional and pharmacological properties of GABAA receptors expressed in brain slices or i

This article presents the work of Swedish film-maker and independent producer Carl Slättne (b. 1937) and analyses his film Urskogen eller kulturen!/‘Wilderness or Civilization!’ (1985). The film is discussed in relation to the concept of the essay film as it has been developed in recent writings by Laura Rascaroli and Timothy Corrigan. The formal devices of Slättne’s film are analysed and put into

The knowledge of the Pd II spectrum and term system has been extended by means of observations with Fourier transform and high dispersion photographic instruments in the infrared (8100 - 40000 Angstrom) and ultraviolet (1040 - 3100 Angstrom) regions. 320 lines have been classified and measured with high accuracy (+/-0.05-0.003 cm(-1) in the infrared, +/-0.002-0.0005 Angstrom in the ultraviolet). T

During the last two or three decades, neuroscience has changed how we understand brain functioning. This shift, which is re-conceptualizing the relationship between the materiality of the brain and consciousness, is bound to have implications for intellectual disability, which is commonly seen as a condition of the brain. At present, examinations of intellectual disability that deploy techniques a

This thesis provides the first attempt to study the nicotinamides and benzamides from a mode of action point of veiw. Understanding the effects on DNA repair, cell cycle control (proliferation) and cell death from these agents and in combination with ionizing radiation, provides a new opportunity to logically develop better approaches to sensitize already existing therapies via for example inducti
