Alkali-stable and highly anion conducting poly(phenylene oxide)s carrying quaternary piperidinium cations

New durable and hydroxide ion conducting anion-exchange membranes (AEMs) are currently required in order to develop alkaline fuel cells into efficient and clean energy conversion devices. In the present work we have attached quaternary piperidinium (QPi) groups to poly(2,6-dimethyl-1,4-phenylene oxide)s (PPOs) via flexible alkyl spacer chains with the aim to prepare AEMs. The bromine atoms of brom

Energy renovation of an office building using a holistic design approach

This paper presents a holistic approach to perform energy renovations of office buildings. A real case study is used to demonstrate how different software can be used to facilitate the work of architects and engineers during different design stages. Initially, the moisture safety of the building is coupled to its energy performance to define the optimum insulation level. The new interior layout is

Clinical, Immunophenotypic and Cytogenetic Features of Megakaryocytic Blast Crisis of Chronic Myeloid Leukemia : A Single Institution Study

We present 15 patients with megakaryocytic (Mk) blast crisis (BC) of a Philadelphia (Ph) chromosome positive CML confirmed by immunophenotype analysis between 1989-2000. The primary aim of this study is to define clinical, immunological, cytogenetic and laboratory characteristics of Mk BC in Ph positive CML. We have done retrospective analysis regarding basic clinical findings, immunologic phenoty

Fattigvård, diakoni och välfärdstjänster - från restriktioner till konkurrensutsättning

The Church has been a dominant actor in the history of care and social support, but it met several restrictions during the 20th Century. The Church of Sweden now has,since the separation from the state A.D. 2000, the possibility to act as a "welfare entrepreneur". But the willingness to do so seems limited. Even if innovative examples are seen the parishes hesitate for organisational and ideologicThe Church has been a dominant actor in the history of care and social support, but it met several restrictions during the 20th Century.

Interrogating the 'valley of wonders' : Some romantic-period debates about Chamonix-Mont Blanc

By the time that Samuel Taylor Coleridge described Chamonix as a Valley of wonders’, in the 11 September 1802 number of the Morning Post, the region was already well established as a key focal point in the European debate about the scientific, aesthetic, political and religious significance of sublime landscape.1 However, Chamonix’s prominence on the cultural map of Europe was also relatively rece
