The Hula Valley has two key Acheulian sites: Gesher Benot Ya'aqov (GBY), a large flake site with hundreds of basalt bifaces and significant number flint handaxes, Ma'ayan Barukh (MB), where more than 3500 handaxes were collected. Over the last one million years, valley was filled by alluvium flows, devoid sources suitable for handaxe production. We conducted archaeological geological surveys co...

Tolerance to high and low temperature is an important breeding aim for Central and Northern Europe, where temperature fluctuations are predicted to increase. However, the extent to which genotypes differ in their response to the whole range of possible temperatures is not well understood. We tested the hypothesis that the combination of maize (Zea mays L.) inbred lines with differing temperatur...

Lithic artefacts are a potential source of information for the study handedness in different human species. In flint flakes, system fractures is developed (parabolic cracks) around point percussion connection with cone and conical fracture flint. The orientation these linked to direction percussion, therefore knapper's handedness. archaeological remains from Levels III, IV, V VI at Axlor (Bizka...

On the basis of the first inducer of maternal haploids in maize (Zea mays L.), Stock 6 (Coe, 1959), a number of new inducer lines have been created (Tyrnov et al, 1984; Lasharmes et al, 1988; Sarkar et al, 1994; Shatskaya et al, 1994; Chalyk, 1999; Rober et al, 2005). The inducers possess dominant anthocyanin marker genes allowing haploids to be identified at different stages (dry seeds, seedli...

Burnt lithic artefacts are regularly discarded from microwear analyses, causing a bias in the functional interpretation of prehistoric sites. This is especially true when burnt lithics numerous as typically case on Mesolithic sites Northern Belgium. stone potentially hold information regarding functional, spatial, and social organisation site. Therefore, investigating impact burning tools, pres...

In this study, the effect of a magnetic field on Flint Glass for optical isolator applications has been reported. A flint glass and laser light source with wavelength 650nm were used as medium source, respectively. The was produced by applying current through coil. linearly polarized passed in presence field, angle rotation measured. plotted versus strength fitted linearly. experimental results...

Extensive habitat loss and changing agricultural practices have caused widespread declines in grassland birds throughout North America. The Flint Hills of Kansas and Oklahoma--the largest remaining tallgrass prairie--is important for grassland bird conservation despite supporting a major cattle industry. In 2004 and 2005, we assessed the community, population, and demographic responses of grass...

Test case prioritisation techniques aim to maximise the chance of fault detection as early in testing as possible. This is most commonly achieved by prioritising the tests according to a surrogate measure that is thought to correspond to fault detection capabilities, such as code coverage. However, once the prioritised test suite indeed detects a fault, the original prioritisation may become ob...
