A critical comparison of two commonly used markers of initial animal domestication, size reduction and demographic profiling, is presented. A metrical analysis of a large collection of modern wild and domestic goats (Capra hircus aegargus and C. h. hircus) from Iran and Iraq clearly demonstrates that sex is by far the most significant factor affecting size in goats. In all post-cranial bones ex...
background: a powerful and improved technique, proton induced x-ray emission (pixe) has been performed-yielding the elemental composition of 17 samples of surgically excised malignant and normal tumors of breast tissue. the samples without any further process as thick targets were put on capton foil backing. there are no homogenizing processes. the pixe spectra analysis was performed using he n...
Knowledge of our ancestor’s diets is becoming increasingly important in evolutionary medicine, as researchers have argued that we have evolved to specific type of ‘Palaeolithic’ diet, and many modern nutritional disorders relate to the mismatch between the diet to which we have evolved, and the relatively newer agricultural-based ‘Neolithic’ diets. However, what is the archaeological evidence f...
BACKGROUND Ageing of population worldwide will be responsible for a major increase of the incidence of osteoporosis in elderly. For the individual, osteoporotic fractures result in great disability as well as loss of quality of life and also represent an enormous burden for healthcare systems. This study was conducted to determine the prevalence of osteoporosis and its association with serum vi...
A central problem in archaeological research has been the chronometric dating of petroglyphs (rock engravings). Recent improvements in the understanding of the chemistry of rock varnish (or patina) that develops on rock surfaces in arid regions has resulted in the development of a calibrated dating technique, cation-ratio (CR) dating. This is based on calibrating chemical changes in minor and m...
Knowledge of the range and chronology of historic trade and long-distance transport of natural resources is essential for determining the impacts of past human activities on marine environments. However, the specific biological sources of imported fauna are often difficult to identify, in particular if species have a wide spatial distribution and lack clear osteological or isotopic differentiat...
PIXE studies of normal and SIV-infected rhesus macaque tissues: investigations of particulate matter
Abstract Positron Emission Tomography (PET) studies [1] of the evolution Simian Immunodeficiency Virus (SIV) (the monkey analogue Human (HIV) have revealed that SIV is localised in different organs at stages infection. Promising routes to completely eradicate HIV virus particles involve therapies target infection cellular level. Our previous μ -Particle Induced X-ray ( μ- PIXE) very large varia...
Archaeology is one of the sectors that can benefit by new surveying techniques (i.e. those ones related to the use of GPS) for the representation and the management of an archaeological site. Another aspect of the archaeological sector that can take advantage from the use of both GPS and GIS instruments is guided visits of archaeological sites. Today, during visits in museums, visitors often us...
The aim of the study was to analyze possible human skeletal remains within the wrappings of a mummy from the Archaeological Museum, Zagreb, Croatia through the use of the multidetector CT (MDCT) technology. Plain X-ray films and MDCT images of the mummy were taken in both frontal and lateral views. In a single volumetric acquisition of the whole body by MDCT 0.75 mm axial slices were obtained a...
Llama (Lama glama) and alpaca (Vicugna pacos) are the only large domesticated animals indigenous to the Americas. Pastoralism occupies a fundamental economic, social and religious role in Andean life. Today, camelid livestock are confined to the ecozone of the puna (above 3,500 masl), while their presence on the Pacific coast during pre-Hispanic times is attested by archaeological skeletal rema...
