Bis(phosphinidene)-capped triiron carbonyl clusters, including electron rich derivatives formed by substitution with chelating diphosphines, have been prepared and examined as proton reduction catalysts. Treatment of the known cluster [Fe3(CO)9(µ3-PPh)2] (1) with various diphosphines in refluxing THF (for 5, refluxing toluene) afforded the new clusters [Fe3(CO)7(µ3-PPh)2(κ2-dppb)] (2), [Fe3(CO)7(µ

The purpose of this study is to deepen and nuance the understanding of employees’ perception of acquisitions involving professional service firms, consultancy firms in particular. The theoretical framework is divided into three sections. Initially, Organizational Identity is presented, followed by Social Identity Theory and lastly Image. The collected material consists of data from seven interview

Mörk materia har funnits sedan tidernas begynnelse, från den Stora Smällen. Under Universums första hundratals miljoner år var tyngdkraften från den mörka materian så kraftfull att den drog till sig den vanliga materian, som muskler till revben, och formade gigantiska strukturer. De första galaxerna växte där dessa strängar möttes.Galaxer kolliderade med andra galaxer, och slogs samman för att

This essay should be regarded as an artifact study and as a foundation for continued research. As very little has been written about younger blackware, the focal point of this study is on key problems such as dating, function and production. The material of the study is from the excavation of Kv. Apotekaren 4, carried out 1979-1980. The stratigraphy of the site was well dated with dendrochronology

The idea that some people completely lack inner speech is of both scientific and popular interest. In a recent study, Nedergaard and Lupyan compared self-reporting high and low inner-speech-prevalence groups and found that participants in the low-prevalence group performed worse on a verbal working memory test and responded more slowly and less accurately during rhyme judgments. These results repr

In contemporary tourism, technology enables travelers to make travel arrangements in various ways, for example they can reserve tickets directly from airlines company’s website or purchase products from online travel agencies. Considering that travelers have many alternatives but insist in making transactions with traditional travel agencies, there must be something that makes traditional travel a

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Antikroppar, även kallade immunoglobuliner, är proteiner som utgör en viktig del i vårt försvar mot infektioner genom att de kan binda och neutralisera ämnen som uppfattas som främmande, t ex bakterier, virus eller produkter som produceras av dessa organismer. Antikropparna består av en antigen-bindande variabel del som binder till deMany bacteria express immunoglobulin(Ig)-binding proteins that interact with Ig in a non-immune manner. Several of these Ig-binding bacterial proteins have been well characterized and are widely used as reagents for analysis and purification of Ig's. Protein G found on group C and G streptococci has affinity for constant regions of IgG heavy chains, whereas protein L found on Peptostreptococcus ma

Detection of P. falciparum-specific subpopulations of B-cells is important for studies of immunity in malaria. This protocol relies on the photostability and protein loading capacity of carboxylated quantum dots to detect a broad range of different P. falciparum-specific B-cells. Infected red blood cell ghosts, obtained by permeabilization of infected cells with Streptolysin O, are coupled with ca
