Edge-wear analysis in Archaeology. The current state of research

The analytical method by which macroscopic and above all microscopic traces of wear are studied, in order to reach conclusions about how flint tools were employed, has been applied with varying success in western archaeology since the 1960s. Two main approaches can be distinguished, where each approach examines somewhat different wear traces using different microscopic equipment. The scanning elec

Measuring progress towards a ‘Green Energy Economy’: Who is really winning the race?

This paper provides the first regional econometric decomposition of CO2 emissions from fuel combustion in eight regions of the world. Using the best publically-available time series data (1971–2011), the analysis examines the key determinants and relationships of the ‘Green Energy Economy’ (GEE) in Africa, Asia, Latin America and the Caribbean, the Middle East, Non-OECD Europe and countries from t

Antidepressant drug effects in vivo: Focus on pharmacokinetic and pharmacodynamic responses in different experimental paradigms

Popular Abstract in Swedish Leverencefalopati (LE) är ett neuropsykiatriskt sjukdomstillstånd som kan ses i samband med en försämrad leverfunktion. Den bakomliggande orsaken till LE är ofta levercirrhos (skrumplever) p.g.a. alkoholmissbruk, men andra orsaker såsom kronisk hepatit, kirurgi, och olika gifter kan också ligga bakom detta. Vid levercirrhos försämras leverns blodflöde p.g.a. en ökad kärPharmacokinetic and pharmacodynamic activities of the antidepressants venlafaxine (VEN) and citalopram (CIT) were investigated in the portacaval shunted (PCS) rat, a model of chronic hepatic encephalopathy (HE), and normal/control rats. The levels of VEN in serum and brain were higher in PCS rats than in controls after a single injection and chronic treatment with VEN (10 mg/kg). After reducing th

Intermediaries and intervenients in normative systems

Many concepts in legal texts are "intermediaries", in the sense that they serve as links between statements of legal grounds, on one hand, and of legal consequences, on the other. In our paper, an algebraic representation of normative systems is used for distinguishing between different kinds of intermediaries and making the idea of a joining between grounds and consequences more precise. In Secti

The Rubber Industry and Extended Producers' Responsibility Framework: Opportunities and Threats for Swedish Rubber Manufacturers

An array of sustainable ways either to reduce the amount of waste rubber generated or for the re-utilisation of waste rubber products as different means of resources at the end of their service lives are provided and briefly evaluated from economic, social and environmental perspectives. Potential measures which the Swedish rubber industry and its major stakeholders can implement (within the conte

Nonergodic dye-to-nanocrystalline semiconductor film electron transfer

The dominating part of electron injection from the transition metal complex Ru(dcbpy)2(NCS)2 into a titanium dioxide nanocrystalline film proceeds extremely rapidly from the initially populated, vibronically nonthermalized, singlet excited state of the molecule. The results are especially relevant to the understanding and design of molecular-based photovoltaic devices and artificial photosynthetic
