The kinetics and mechanism of the reactions between trans-[PtI3(PPh3)]– and trans-[PtI3(SbPh3)]– with pyridine, 2- and 4-methylpyridine in acetonitrile solvent have been studied by stopped-flow spectrophotometry. The crystal and molecular structures of the tetrabutylammonium salts of the two anions have been determined. Substitution of iodide trans to stibine is reversible and takes place via paraThe kinetics and mechanism of the reactions between trans-[PtI3(PPh3)]– and trans-[PtI3(SbPh3)]– with pyridine, 2- and 4-methylpyridine in acetonitrile solvent have been studied by stopped-flow spectrophotometry.

In this thesis, I have conducted a descriptive, comparative study to highlight the differences between the UN peacekeeping mission in Mali and the special political mission (SPM) in Libya, with regards to the promotion of democratic development and direct support to facilitate such development. My study will show that even though the ambitions and the nature of the support is almost identical, the

In previous years, substantial research has focused on walkability, primarily examining how the built environment affects walking behavior. However, these studies have predominantly defined walkability through physical and social factors, with limited exploration of its spatial dimension. This article seeks to address this gap by examining the spatiality of walkability through Lefebvre’s spatial t

This paper critically examines sexual risk reduction interventions, more specifically how they are evaluated and the implications that this has for sexual health policy. The focus is on motivational interviewing (MI) interventions which aim to promote protective behaviors related to sexual risk on the part of young people. MI has become increasingly popular, largely due to it being a highly flexib

Recent studies of beetle specimens deposited in collections have revealed five species new to the Swedish fauna to be hiding amongst their closely related species. In some cases, the species known to the Swedish fauna are widespread and considered common, making it easy to overlook the slight differences that separate them from the similar and less common species. Some of these species are restric

In this study, we investigate how eco-social attitudes are interlinked with various modes of political action aimed at preventing environmental change and promoting social welfare. Using multiple correspondence analysis and cluster analysis, we explore the links between attitudes and political action, and associated socio-political characteristics, in the case of Sweden. Our results show a three-nIn this study, we investigate how eco-social attitudes are interlinked with various modes of political action aimed at preventing environmental change and promoting social welfare.

This thesis covers the estimation of the fracture behaviour of the European wood species Norway spruce and birch. The fracture behavior of wood can be quantified through three material parameters: the stiffness, the strength, and the specific fracture energy. In the present work, these parameters are characterized through two methods.The first method is purely experimental and only estimates one pThis thesis covers the estimation of the fracture behaviour of the European woodspecies Norway spruce and birch.

From at least the Late Neolithic through the end of the Bronze Age and onwards, people continued to inhabit the settlement of Asine. For this reason, the site makes an interesting starting point for discussing long term change. This short paper presents new data on the animal bones from Bronze Age Asine. The data set is used for a zooarchaeological discussion of the site from a diachronic perspectFrom at least the Late Neolithic through the end of the Bronze Age and onwards, people continued to inhabit the settlement of Asine.

Image quality has always been a matter of great importance for anyone working with or consuming images and videos. Images and videos are, in general, for human consumption. Thus, image quality is essentially a subjective attribute of an image. Though there exist both objective and subjective approaches to assessing image quality, objective results may not correlate well with subjective resultImage quality has always been a matter of great importance for anyone working with or consuming images and videos. There exist both objective and subjective approaches to assessing image quality. Example metrics of the former include PSNR and SSIM, both of which mathematically compare pixels of the original image with the equivalent pixels of the distorted or changed image. Objective methods are f

This project aims to highlight the manufacturer as an important asset in product development. In order to design a product, it is necessary, especially for industrial designers to have good knowledge of the manufacturing technologies that are available and to have knowledge of the working environments in which our ideas are put into practice. Increased cooperation between local actors opens opport

The paper employs Jegadeesh and Titman (1993)’s overlapping ranking period method to build winner-portfolio and loser-portfolio, and thereafter conducts empirical studies on the momentum and contrarian effects on the Chinese stock market from 2000 to 2010. One thing worth mentioning here is that the author processes the data using her own Matlab codes instead of doing tremendous manual work. It is

The Svalbard Seed Vault serves as a backup against accidental loss of genetic crop diversity within the existing global conservation system. Addressing this objective, this thesis repeats the 2013 assessment of the Seed Vault’s completeness relative to the global conservation system as performed by Westengen et al (2013, 1). It is shown that gaps have continued to exist in Svalbard’s collection. S

Research regarding remittances and development has long been plagued by a gender-neutral approach. Consideration is rarely given to why female migrants remit differently. Prior research suggests that female remitters may experience increased burdens and pressure to remit. Media effects theories dictate that the ways in which media is disseminated and consumed has societal impacts and consequences.
