Law, Norms, Piracy and Online Anonymity – Practices of de-identification in the global file sharing community

Purpose The purpose of this study is to better understand online anonymity in the global file-sharing community in the context of social norms and copyright law. The study describes the respondents in terms of use of Virtual Private Networks (VPNs) or similar services with respect to age, gender, geographical location, as well as analysing the correlation with file-sharing frequencies.

Light Protection in Plants: Characterisation of Violaxanthin de-epoxidase

Växter behöver ljus. Ljuset omvandlas genom fotosyntesen till kemisk energi som kan lagras i växten. Mer ljus ger således mer energi men bara upp till en viss gräns. När växten inte längre kan hantera mängden ljus som den utsätts för kommer flaskhalsar i processen orsaka att högenergetiska tillstånd blir mer långlivade. Dessa reaktiva ämnen kan då orsaka skada på närliggande komponenter, vilket kaPlants and algae need light to drive the photosynthetic machinery. An excess of light will, however, result in damage to the photosynthetic machinery and to the rest of the organism. The surplus of energy, when exposed to light stress is converted into less harmful heat energy through a process called non-photochemical quenching. This quenching is partly dependent on the xanthophyll pool located i

Exopolysaccharides production by cultivating a bacterial isolate from the hypersaline environment of salar de uyuni (Bolivia) in pretreatment liquids of steam-exploded quinoa stalks and enzymatic hydrolysates of Curupaú sawdust

The halotolerant bacterial strain BU-4, isolated from a hypersaline environment, was identified as an exopolysaccharide (EPS) producer. Pretreatment liquids of steam-exploded quinoa stalks and enzymatic hydrolysates of Curupaú sawdust were evaluated as carbon sources for EPS production with the BU-4 strain, and the produced EPS was characterized using FTIR, TGA, and SEM. Cultivation was performed

Experimental Study of De-icing Salt-frost Scaling in Concrete with Low-calcium Fly Ash or Slag : Influence of Drying and Carbonation, and Air Content

In order to reduce the net climate impact of concrete production, it is necessary for the industry to undertake several actions. Among these is to include fly ash and slag as supplementary cementitious materials. Accordingly, this project has studied concrete containing low-calcium fly ash or ground-granulated blast-furnace slag. In incorporating fly ash or slag as supplementary material, the ceme

Stable coexistence of two Caldicellulosiruptor species in a de novo constructed hydrogen-producing co-culture

Background Mixed culture enrichments have been used frequently for biohydrogen production from different feedstock. In spite of the several advantages offered by those cultures, they suffer poor H2 yield. Constructing defined co-cultures of known H2 producers may offer a better performance than mixed-population enrichments, while overcoming some of the limitations of pure cultures based on synergi

Mitos, ciudades y cine: un viaje de ida y vuelta.

Myth, from the Greek mythos: “Mar-velous narration situated outside historic time told by divine or heroic characters. Often interprets the world’s origin or great human events”. The dragon, ex-cept for in China, has always been a symbol of “evil”, but, at the same time, the fire and power represented by the dragon are essential elements for hu-mankind. The modern city, symbolically under-stoo

Energy security under de-carbonization scenarios: An assessment framework and evaluation under different technology and policy choices

How would a low-carbon energy transformation affect energy security? This paper proposes a frame- work to evaluate energy security under long-term energy scenarios generated by integrated assessment models. Energy security is defined as low vulnerability of vital energy systems, delineated along geographic and sectoral boundaries. The proposed framework considers vulnerability as a combination of

De novo assembly of the dual transcriptomes of a polymorphic raptor species and its malarial parasite.

Studies of non-model species are important for understanding the molecular processes underpinning phenotypic variation under natural ecological conditions. The common buzzard (Buteo buteo; Aves: Accipitriformes) is a widespread and common Eurasian raptor with three distinct plumage morphs that differ in several fitness-related traits, including parasite infestation. To provide a genomic resource f

Writing in Deconstruction vs Speech in Structuralism (Jacques Derrida vs Ferdinand de Saussure)

Speech is already in itself a writing. Any concept that is to name, to stay for the abstract or concrete reality is made up of a mental trace. There is always a sleepy-waiting yet ever present trace at the origin of the representation and the naming of any ontological phenomenon. The trace is itself The apriori ontology – and this is how writing is pre-eminent to the later formal verbalization of

Reverse pharmacology and the de-orphanization of 7TM receptors

Approximately 800 genes coding for seven-transmembrane, G-protein-coupled receptors have so far been recognized. In spite of this, many of these receptors are defined by their sequence only, and are therefore classified as orphan receptors. Without knowing what their endogenous ligands are, we lack the information needed to understand their physiological role and hence cannot make use of them as d

De-tabooing dying control - a grounded theory study.

Dying is inescapable yet remains a neglected issue in modern health care. The research question in this study was "what is going on in the field of dying today?" What emerged was to eventually present a grounded theory of control of dying focusing specifically on how people react in relation to issues about euthanasia and physician-assisted suicide (PAS).
