Chronic low back pain can be considered to be one of the most frequently treated and most costly diseases in modern industrial societies. Dysfunctions and imbalances of the spine-supporting muscles increase the risk of low back pain. Consequently preventive treatment and rehabilitation have to aim at preserving and restoring the full capacity of the(More)
Handheld X-ray fluorescence spectrometry (XRF) has seen a dramatic increase in use for archaeological projects. The attraction of the technique is its portable and nondestructive nature. In many cases, the archaeological artefacts in question cannot be destructively sampled, or the piece itself cannot be sent to an analytical laboratory. One of the current(More)
It is shown that energy-dispersive X-ray diffraction (EDXRD) implemented in a back-reflection geometry is extremely insensitive to sample morphology and positioning even in a high-resolution configuration. This technique allows high-quality X-ray diffraction analysis of samples that have not been prepared and is therefore completely non-destructive. The(More)
Frankincense, the oleogum resin from Boswellia sp., has been an early luxury good in both Western and Eastern societies and is particularly used in Christian funerary and liturgical rites. The scant grave goods in late medieval burials comprise laterally perforated pottery vessels which are usually filled with charcoal. They occur in most regions of western(More)
The provenance of the flux raw material used in the manufacturing of Roman glass is an understudied topic in archaeology. Whether one or multiple sources of natron mineral salts were exploited during this period is still open for debate, largely because of the lack of a good provenance indicator. The flux is the major source of B in Roman glass. Therefore,(More)
Archaeology is an interdisciplinary science par excellence. In its quest to reconstruct human behavior in the natural and cultural environment of the past, archaeology uses knowledge and techniques from many different academic disciplines. Indeed, there are very few sciences that have no relevance to archaeology. The concept of “holistic archaeology” was(More)
