The labilised clusters [Os3(CO)11–nLn(NCMe)][n= 1, L = PMe3 or CNBut; n= 2, L = P(OMe)3] have been prepared. The reaction of [Os3(CO)11 –nLn(NCMe)] or [Os3(CO)10{P(OMe)3}(NCMe)] with either [Os3(CO)11(PH3)] or [Os3(µ-H)(CO)10(µ-PH2)] led to the formation of the phosphide-bridged clusters [Os6(µ-H)(CO)21{P(OMe)3}(µ-PH2)], [Os6(µ-H)(CO)21(PMe3)(µ-PH2)], [Os6(µ-H)(CO)21(CNBut)(µ-PH2)], [Os6(µ-H)(CO)2

Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. The conversion of

Popular Abstract in Swedish Data från AVHRR-sensorn ombord på NOAA satelliten används operationellt för att övervaka vegetation och torka i global och regional skala. Ett vegetationsindex (NDVI) används som en indikator på grön växtbiomassa. Analys av AVHRR NDVI-data över Östafrika pekar på att det finns ett starkt samband mellan den ytmässiga fördelingen av vegetation och NDVI i arida och semi-aIn this thesis, an assessment is made of the performance of the Normalized Difference Vegetation Index (NDVI) derived from coarse resolution data from the NOAA AVHRR sensor, with particular reference to mapping and monitoring of drought and vegetation in East African vegetation and climatic conditions. Methods for analysing time series of satellite data are investigated. By studying the empirical

The effects of increasing age on skeletal muscle fatigue and endurance were assessed in 22 healthy young (14 men and 8 women; mean age, 28 +/- 6 years) and 16 healthy old (8 men and 8 women; mean age, 73 +/- 3 years) individuals. All subjects performed 100 repeated maximum dynamic knee extensions at 90 degrees.s-1 (1.57 rad.s-1) using an isokinetic dynamometer (Cybex II). Peak torque was recorded

SBA-15 was synthesised with Pluronic P104 ((EO)(27)-(PO)(61)-(EO)(27))) its Structure promoter at 45 degrees C, with and without NaCl (1.0 M) added to the Synthesis Mixture. TEOS (tetraethyl orthosilicate) was used as silica source. The formation process was studied by in-situ SAXS/SAXD using synchrotron light. Addition of salt affects the micellar size, initial cell-parameter of the 2-D hexagonal

Today, cognitive impairment can be successfully treated with acetylcholine esterase inhibitors (AChE-I) in many, but not all, patients with Alzheimer's disease (AD). To investigate the relation between tacrine treatment, inheritance of ApoE epsilon4 alleles, and rate of progression, the differences in MMSE and CIBIC scores (efficacy parameters) after 6 and 12 months of tacrine (an AChE-I) treatmen

The evolutionary process and its impact on speciation and emergence of genera is discussed briefly for the Teloschistaceae. Many facts which have been recognized mainly from studies of morphological variation within populations in addition to analyses of structural variation from herbarium material speak for a conceivable slow evolutionary process represented in this family. Some examples are disc

The aim was to investigate the influence of age and gender on quality of life (QoL), complaints, and the presence and nature of self-reported diseases in persons aged 75 and older with cancer (n = 150), compared to a matched group without cancer (n = 138). A second aim was to investigate factors associated with poor QoL in people aged 75 and older. QoL was measured with Short Form (SF-12) and Euro

The study aims at investigating the use of Landsat thematic mapper (TM) for mapping leaf area index (LAI) in coniferous and deciduous forests in southern Sweden. LAI has been estimated in the field with optical measurements, allometric equations, and litter-trap data, and empirical relationships between LAI estimates and satellite-measured reflectances have been analysed. Several common vegetation

An extended Keldysh formalism, well suited to properly take into account the initial correlations, is used in order to deal with the time-dependent current response of a resonant tunneling system. We use a partition-free approach by Cini in which the whole system is in equilibrium before an external bias is switched on. No fictitious partitions are used. Despite a more involved formulation, this p

Health promotion has become a widespread concept, although little empirical research as to its importance and outcome has been performed in the mental health field. The aim of the present study was to investigate the construct validity of a newly developed Health Promotion Intervention Questionnaire, intended to measure patients' subjectively experienced health-promoting interventions within menta

The aim of this study is to examine the characteristics of the Argentine writer Juan Jose Saer’s Nadie nada nunca (1980) and how literary perception is explored in this novel. The first part of the thesis deals with Saer’s works in general, and includes a short overview of his novels, his short stories, his poems and his essays, with special emphasis on his theoretical discussions about literature
