Dilute solutions of the square-planar tetra-aqua complex pt(H2O)42+ have been prepared in a 1.00 M perchloric acid medium by addition of excess silver(I) perchlorate to potassium tetrachloroplatinate(II), equilibration at 70°C, filtration of the silver chloride precipitate, and subsequent separation of the excess silver from the solution by electrolysis. The complex has also been prepared by addit
This thesis studies the impact of the war in Ukraine on stock prices of firms within the European defense industry. While previous studies have examined the effects of war on stock prices of defense firms, fewer studies specifically focus on the war in Ukraine. Furthermore, this thesis focuses solely on European defense firms, offering a new geographical perspective to the topic. Additionally, the
This Master’s thesis is a sociolinguistic case study about intra-sentential code-switching, also known as code-mixing, between colloquial Moroccan Arabic and French. The data is collected by arranged interviews with focus groups consisting of university students in Rabat, Morocco, in order to investigate the trends and the extent of the occurrence of French in speech situations where intra- senten
This essay raises the question as to whether a general principle of passivity exists within the Swedish law. This is a question that has been discussed by practicing lawyers for decades, but which has become increasingly relevant recently as a result of HD's intensive treatment of the passivity issue. Within the Swedish law, freedom of contract prevails with the premise that a party only becom
At self-similarity the strain history is implicit in and deducible from the strain field at each instance of the loading process. This fact is taken advantage of in a FEM-technique which allows the load to be applied in one single step, only, even when the incremental theory of plastic flow has to be used.Two self-similar problems are solved. Firstly an analytically solvable anti-plane strain crac
The need for energy in water provision and use is obvious, however the drivers are often complex, difficult to assess, and often inconsistently presented. Here we build a clearer definition and conceptual framework of “water-related energy”. We apply this framework to harmonise data and results across disparate studies so that regional estimates of water-related energy can be compared in a consist
Over the last decade it has been pointed out by several philosophers that not all Status Function Declarations are synchronic: some such declarations are directed toward the absolute past. Such Status Function Declarations are perplexing if one is an ontic realist with respect to institutional properties and states of affairs. If successful, such Status Function Declarations seem to change the abs
Background and aim: Ischemia-reperfusion (I/R) in the intestines activates leukocytes and reactive oxygen species (ROS) and leads to lipid peroxidation and DNA damage. Rosehips have a high content of polyphenols and might prevent lipid peroxidation. Some Lactobacillus species are capable of degrading polyphenols to simpler and non-toxic constituents, sometimes with enhanced antioxidative capacity.
The antimicrobial gas carbon dioxide is frequently used in modified atmosphere packaging. In the present study, the effects of CO2 (10 to 70%, vol/vol) on gene expression (measured using quantitative reverse transcription-PCR and a whole-genome DNA microarray) and neurotoxin formation (measured using an enzyme-linked immunosorbent assay [ELISA]) by proteolytic Clostridium botulinum type A1 strain
Does perfluorooctane sulfonate (PFOS) and perfluorooctanate (PFOA) exposure disrupt the menstrual cyclicity? The female reproductive system may be sensitive to PFOA exposure, with longer menstrual cycle length at higher exposure. PFOS and PFOA are persistent man-made chemicals. Experimental animal studies suggest they are reproductive toxicants but epidemiological findings are inconsistent. A cros
The characterization of the incident photon beam is usually divided into its dependence on collimator setting (head-scatter factor) and off-axis position (primary off-axis ratio). These parameters are normally measured "in air" with a build-up cap thick enough to generate full dose build-up at the depth of dose maximum. In order to prevent any influence from contaminating electrons, it has been re
This article presents a new method for conjugate view activity quantification for 131I-labeled monoclonal antibody distribution. METHODS: The method is based on the combined use of images from 3 modalities: whole-body (WB) scintillation camera scanning, WB transmission scanning using 57Co, and CT. All images are coaligned using a recently developed program for the registration of WB images. Correc
Aim: The primary aim of this study was to describe alcohol involvement in relation to gender and different age cohorts among freshmen at two Swedish universities. The secondary aim was to investigate whether the results were related to a likelihood of students being in serious relationships and/or had a first-degree relative with alcohol problems. Methods: Two complete cohorts of university freshm
