Absorption and fluorescence spectral properties of J-aggregates of core-tetrasubstituted perylene bisimide (PBI) dyes have been investigated in the temperature range from 300 to 5 K. A special feature of the present PBI J-aggregates is that, in contrast to classical J-aggregates like that of pseudoisocyanine (PIC), the chromophores are held together not only by van-der-Waals interactions but also
We report an investigation of the structural and dynamic properties of mixtures of food colloid casein micelles and low molecular weight poly(ethylene oxide). A combination of visual observations, confocal laser scanning microscopy, diffusing wave spectroscopy, and oscillatory shear rheometry is used to characterize the state diagram of the mixtures and describe the structural and dynamic properti
The use of new powerful nested polymerase chain reaction (PCR) techniques to identify and screen for prevalence of parasites has a huge potential. It allows for the detection and identification of low-intensity infections, but its high sensitivity and technical setup may also induce problems. Here, we report a cautionary note regarding misleading amplification of avian malaria species (Haemoproteu
Positional cloning of susceptibility genes in complex diseases like rheumatoid arthritis in humans is hampered by aspects like genetic heterogeneity and environmental variations, while genetic studies in animal models contain several advantages. With animal models, the environment can be controlled, the genetic complexity of the disease is minimized and the disease onset can be predicted, which si
We conducted a cross-sectional pilot study on healthy pre-menopausal women (aged 45-50 years) living in Granada, in the south of Spain (n = 39) and Malmo, in the south of Sweden (n = 38) in order to compare their plasma carotenoid levels and to investigate the relationship between the differences in food consumption. Plasma concentrations of six carotenoids were measured using high performance liq
The modeling of industrial combustion applications today is almost exclusively based on two-equation turbulence models. Despite its known limitations, the most the widely used model is still the standard k-ε model. The objective of this paper is to investigate the performance of two-equation turbulence models applied to a confined swirling flow. Numerical modeling of an axis-symmetric confined sud
We predictably believe that immense natural resources would generate large revenues and wealth within a country. Nevertheless, a lot of evidences show the contrary. Empirical studies find that resource abundance, economic collapse, civil wars, and political instability are well correlated. This indeed creates a complex puzzle as to why natural blessing has not always brought wealth in most resourc
Modern technology has brought opportunities to reach an audience beyond national, cultural and social borders. The intention of the study is to explore how rhetoric can be used as a practical and analytical tool to overcome conflict and create unity between the speakers and their audience. In other words: How can rhetoric be used as a community- and identitybuilding resource to reduce the distance
The Clean Development Mechanism (CDM) is a mechanism under the Kyoto Protocol, which allows industrialised countries that have binding emission targets to invest in emission reduction projects in non-industrialised countries. These CDM investments generate certified emission reductions (CERs), which can be used by the industrialised countries towards meeting their own targets. The dual objective o

This Master thesis treats development studies of an elevated light fixture from Pre study to prototype. The project is carried out in cooperation with Safegate Interna-tional AB and the Machine Design Department at the University of Lund. Throughout the project a combination of the methodologies, Ullrich and Eppinger’s “Product Design and Development” and Pahl and Beitz’s “Engineering design, a sy

Swedish has – like other Germanic languages – flexible stress placement, which underlies morphological rules and is also based on the individual word’s origin. The achievement of the correct usage when learning Swedish is challenging. As second language learners of Swedish in the classrooms present speakers of a variety of first languages (L1s), the opportunity has been taken to have a closer look
Galectins are carbohydrate binding proteins, implicated in conditions of both inflammation and cancer. Connections between chronic inflammation and cancer are proposed by the increased remodelling and proliferation that occurs, leading to enhanced survival and proliferation of malignant cells. Since galectins have been implicated in mechanisms of both chronic inflammation and cancer, we have inves
