The effect of incorporating modified clay into a polyamide 6 (PA6) matrix, on the free volume cavity sizes and the thermal and viscoelastic properties of the resulting nanocomposite, was studied with positron annihilation lifetime spectroscopy, differential scanning calorimetry and dynamic mechanical analysis. At low concentrations of clay the fraction of PA6 crystals melting close to 212 degrees

There are currently only six countries in Africa that can be considered as free. However, none of them are yet democratically consolidated. Thus, the purpose of this study is to examine what issues remains to be dealt with for these countries to become democratically consolidated. The method used is a case study on Namibia that is based on the theory by Linz and Stepan. The findings are that Namib

Free clusters produced by a co-expansion of argon and krypton have been studied by means of core level photoelectron spectroscopy. In this study we have determined: (i) the produced clusters are heterogeneous; (ii) the radial distribution of the two atomic species in the cluster differs. The proposed structure model places the majority of the krypton atoms in the bulk, leaving the argon atoms to b

Bacteria can cause life-threatening infections, such as pneumonia, meningitis, or sepsis. Antibiotic therapy is a mainstay of treatment, although antimicrobial resistance has drastically increased over the years. Unfortunately, safe and effective vaccines against most pathogens have not yet been approved, and thus developing alternative treatments is important. We analyzed the efficiency of factor

The ability for groups to engage in collective action depends on a variety of factors, ranging from social organization to resources to political opportunities amongst others. Yet, on a much more basic level, collective action is dependent on the ability of individuals to come together to interact and coordinate action, or in other words, to create a collective. Individuals must have spaces in whi

We investigated visual working memory encoding across saccadic eye movements, focusing our analysis on refixation behavior. Over 10-s periods, participants performed a visual search for three, four, or five targets and remembered their orientations for a subsequent change-detection task. In 50% of the trials, one of the targets had its orientation changed. From the visual search period, we scored
