The evidence-based analysis of people's navigation and wayfinding behaviour in large-scale built-up environments (e.g., hospitals, airports) encompasses the measurement and qualitative analysis of a range of aspects including people's visual perception in new and familiar surroundings, their decision-making procedures and intentions, the affordances of the environment itself, etc. In our research
A novel isolation and purification method was developed for producing 1,3-propanediol with high purity and high yield from the mixture containing 1,3-propanediol, 1,2-propanediol, glycerol, and glucose. The developed method, which consisted of phase separation and chromatography, was found to be a simple and efficient procedure for the isolation and purification of 1,3-propanediol from the other c
Nano-LEDs, with sizes smaller than 1 μm and close to sub-wavelengths, have received increasing attention because of their potential applications in next-generation self-emissive displays, visible light communication, optogenetics, maskless lithography, on-chip super-resolution microscopy, etc. In contrast to the top-down fabrication of nano-LEDs, where the efficiency drop caused by dry-etching rel
Use of feedforward can alleviate feedback and adaptive actions. Feedforward signals can be generated from reference models and the same models can also be used as reference models in adaptive control. A method for designing the reference models is presented in the paper. By exploiting the structure of the equations describing air vehicles it is possible to find reference models that scale to the p
The European Spallation Source, now under construction in Lund, Sweden, aims to be the world's most powerful pulsed neutron scattering facility. Driving the neutron source is a 5 MW superconducting proton linear accelerator operating at 4 percent beam duty factor and 14 Hz repetition rate. Nineteen partner institutions from across Europe are working with the Accelerator Division in Lund to design
Critical thinking is an important aim of higher education, and it is a skill particularly important in interdisciplinary fields. I am proposing a seminar where, based on an initial text and some central discussion questions, we can discuss our experiences with teaching and learning in an interdisciplinary manner. The experience from sustainability-related teaching shows that addressing interdiscip
Globalization has increased in recent decades, resulting in structural changes of production and labor demand. This paper examines how the increased global engagement of firms affects the structure of the workforce. We find that the aggregate distribution of occupations in Sweden has become more skilled between 1997 and 2013. Moreover, firms with a high degree of international orientation have a r
A combination of supercritical carbon dioxide (scCO2) impregnation of pyrrole and sonochemical transformation of permanganate (KMnO4) was used to impart conductive and catalytic properties to silk fibers. The results indicated that the conductivity (from polypyrrole –PPy) and catalytic activities (from manganese dioxide –MnO2) were independent and complementary within the processing parameters use
The mode of enquiry in African economic history has changed quite radically in recent years. In 1987, Patrick Manning surveyed practices and databases in African economic history and compared empirical strategies of scholars who studied the African past. Current practice, which A. G. Hopkins called “new African economic history,” incorporates econometric methods. The specific methods chosen and th
Semiconductor nanowires are widely considered as promising candidates for next generations of electronics and optoelectronics. Gold seed particles have so far been recognized as the most important catalyst for growth of nanowires. Costs related to substrates, lithography processes and gold consumption most strongly influence the final cost of nanowire-based devices. An optimum gold deposition proc
Due to rapid development of bacterial resistance against antibiotics, an emerging health crisis is underway, where ‘simple’ infections may no longer be treatable. Antimicrobial peptides (AMPs) constitute a class of substances attracting interest in this context. So far, research on AMPs has primarily focused on the identification of potent and selective peptides, as well as on the action mode of s
Pathogenic mutations in presenilin 1 (PS1) are associated with ≃50% of early-onset familial Alzheimer disease. PS1 is endoproteolytically cleaved to yield a 30-kDa N-terminal fragment (NTF) and an 18-kDa C-terminal fragment (CTF). Using COS7 cells transfected with human PS1, we have found that phorbol 12,13-dibutyrate and forskolin increase the state of phosphorylation of serine residues of the hu
