The body size of wild boar during the Mesolithic in southern Scandinavia
In order to study the body size of wild boar Sits scrofa Linnaeus, 1758 during the Boreal and Atlantic Chronozones in southern Scandinavia, 12 measurements of teeth and bones from 32 Mesolithic sites from Scania (Sweden) and Zealand and Jutland (Denmark) were analysed. The osteometric analysis revealed that the body size of wild boar from Scania did not change during the period. The results indica
Planar and tubular solid oxide fuel cells - Comparison of transient process behaviors
Long-term population dynamics and in situ physiology in activated sludge systems with enhanced biological phosphorus removal operated with and without nitrogen removal
Quantitative fluorescence in situ hybridization (FISH) and the combination of FISH with microautoradiography (MAR) were used in order to study the long-term population dynamics (2.5 years) and the in situ physiology in two parallel activated sludge pilot systems with enhanced biological phosphorus removal (EBPR). The two systems received the same influent wastewater, but were differently operated

Cord blood islet autoantibodies are related to stress in the mother during pregnancy.
A 2-month psychological questionnaire concerning pregnancy was answered by 20,920 nondiabetic mothers of singletons. Retrospective analysis showed increased levels of islet autoantibodies (1A) in 290 (1.4%) newborns. High IA levels in the child's cord blood correlated strongly with IA levels in the mother (GADA r = 0.91, P < 0.0001; IA-2A r = 0.75, P = 0.0001). High IA levels were found in newborn
Direct observation of the non-supported metal nanoparticle electron density of states by X-ray photoelectron spectroscopy
Synchrotron-based X-ray photoelectron spectroscopy on copper and silver cluster beams created by a magnetron-based gas-aggregation source has allowed mapping the electron density of states (DOS) of free metallic nanoparticles. The cluster DOS profiles obtained in the experiments strongly resemble the infinite solid DOS shapes, but the extracted cluster work-functions are lower than those for the b
Intermediate resonance excitation in the gamma p -> p pi(0)pi(0) reaction
The helicity dependence of the total cross section for the (gamma) over right arrow(p) over right arrow -> p pi(0)pi(0) reaction has been measured for the first time at incident photon energies from 400 to 800 MeV. The measurement, performed at the tagged photon beam facility of the MAMI accelerator in Mainz, used the large acceptance detector DAPHNE and a longitudinally polarized frozen-spin targ
Environmental Monitoring - using diode-laser-based spectroscopic techniques
Monitoring of environmental gases is necessary to understand the complex processes governing global warming and the impact of pollutant emissions related to human activity. Diode-laser-based spectroscopic techniques, being robust and affordable, have a great potential to become an industrially well-established technology for environmental sensing. This thesis deals with the further development of
One week sweating simulation test with a thermal foot model
This study aimed to find out how the insulation of the footwear changes over one week of use. A thermal foot model with 8 measuring zones and 5 “sweat glands” was used for tests. A thin sock was donned on the model to allow better water distribution all over the foot surface. Four boots were tested over a period of 5 days. Each day was divided into 9 hour measurement period and 15 hour conditionin
Performance of an On-Demand Beam Excitation System for PIXE Analysis
A system for electrostatic on-demand beam excitation in PIXE analysis has been built and carefully tested. Significantly increased count rate capability without any need for corrections for electronic dead time and with less target deterioration makes the system superior to a traditional system with electronic pile-up rejection. By adding a fast external electronic pulse pile-up rejection system,
Learning Idiomaticity : A Corpus-Based Study of Idiomatic Expressions in Learners' Written Production
The aim of this study is to investigate how Swedish learners of English (at different levels of proficiency) master idiomaticity in their target language. I argue that idiomaticity can be related to the storage and use of multi-word expressions that are preferred by native speakers. These multi-word units are referred to as prefabs in the present study. By manually identifying and subsequently cla
Synthesis of a C3-symmetric macrocycle with alternating sugar amino acid and tyrosine residues
A C3-symmetric macrocycle with alternating sugar amino acid and tyrosine residues was synthesized in seven steps from tyrosine tert-butyl ester and a sugar amino acid precursor derived from D-glucosamine. An Fmoc-protected D-glucosamine derivative was oxidized at C-6 to give the sugar amino acid, which was immediately coupled to tyrosine tert-butyl ester to produce an orthogonally protected buildi
Search for Linking Transitions in 143Eu
An experiment was performed with the Gammasphere Ge-detector array, and the Microball charged particle detector, to search for transitions involved in the decay from the yrast superdeformed band in Eu-143. Sum spectra in coincidence with single, double, and triple gates on SD transitions were produced to search for previously reported two-step links between the superdeformed and the near-yrast ND
How can we use computers to enhance learning?
How do we, in a basic statistics course, create a learning environment where the computer is a natural tool? Different aspects to be considered are the students' feeling of ownership and the importance of integrating the computer exercises in the course syllabus. The teacher has different tools to achieve a computer-supported learning environment and we give some examples. The actual design of the
2,6-Bis(5,6-dicyclohexyl-1,2,4-triazin-3-yl)-pyridine-dichloromethane-wa ter (1/1/0.625)
The title compound, 2,6-bis(5,6-dicyclohexyl-1,2,4-triazin-3-yl) pyridine, C35H57N7.CH2Cl2.0.625H(2)O, crystallizes with two molecules in the asymmetric unit, along with 1.25 molecules of water and two molecules of dichloromethane. The water molecules are involved in hydrogen-bond interactions with some N atoms of the triazine rings.

Sensor and biosensor based on Prussian Blue modified gold and platinum screen printed electrodes
Gold (Au) and platinum (Pt) screen-printed electrodes were modified with Prussian Blue (PB) for the development of amperometric sensors selective for hydrogen peroxide detection. The sensors exhibited sensitivities towards H2O2 equal to 2 A M−1 cm−2 for Au and 1 A M−1 cm−2 for Pt electrodes. The sensors were also employed as the basis for construction of glucose biosensors through further modifica
