The electrostatic and hydrophobic interactions in aqueous solutions of hydrophobically-modified water-soluble non-ionic or ionic polymers, their mixtures with a second polymer, nonionic or of opposite charge, and their mixtures with surfactants of opposite charge have been investigated. The relative strength of the electrostatic and hydrophobic contributions has been modulated by a variation of th

Aside from the oceans, the world’s forests constitute the most vital element in maintaining a climate which sustains life on Earth. The forests supply all living creatures with the basic elements essential for our survival. In this volume, experts, scientists and scholars from a wide range of disciplines set out to discuss a broad range of aspects concerning humans’ relationship to forests. What d

Optimisation of radiographic procedures require solid tools for evaluation of the image quality in order to ensure that it is sufficient to answer the clinical question at the lowest possible absorbed dose to the patient. Lumbar spine radiography is an examination giving a relatively high dose and good methods for evaluation of image quality as well as dose are needed. We have developed and used a

The thinking in law and politics during 1853 and 1914 is exposed.

Viktor Rydberg (1828–1895) kämpade under hela sitt verksamma liv för humanistiska ideal. Ryktbarhet vann han som diktare. Mindre känd är han som forskare och kulturhistoriker. I boken lyfter tjugotre forskare från nio humanistiska ämnen fram Rydbergs betydelse för dagens humanistiska forskning.

Bone mass in adolescents and young adults was studied with regard to its age-related change and its determinants. Methodological aspects of bone mass measurements and their ability to predict future fractures were investigated. Bone mineral content (BMC) and bone mineral density (BMD) were assessed by the Single Photon Absorptiometry (SPA) and Dual Energy X-ray Absorptiometry (DXA) techniques. We

The main objective of Task 23 Small Scale Reformers for On-site Hydrogen Supply has been to provide a basis for harmonization of technology for on-site hydrogen production from hydrocarbon s– fossil and renewable. The four sub-objectives were to: • Develop a basis for harmonized capacities for the on-site hydrogen reformer unit • Identify and examine issues related to the promotion of widespread u

The aim of this paper is to present the software development techniques used to build the EIS Patterns development framework, which is a testbed for a series of techniques that aim at giving more flexibility to EIS in general. Some of these techniques are customizations or extensions of practices created by the agile software development movement, while others represent new proposals. This paper a

The Holocaust takes on different significance whether is it perceived as belonging to Jewish historical culture, to Hungarian historical culture or to Romanian historical culture – or whether these historical cultures are thought of, in ethnic terms, as bivalent. Thus, using the same concepts as the ones concerning certain individuals’ orientation in a bicultural environment, one can argue that th
