T his chapter argues that there are multiple adaptations underlying the distinctiveness of the human mind. Careful analysis of the capacities that are involved in the creation, acquisition, and transmission of culture and cultural products suggests that it is very unlikely that these could be underlain by just one, or even a few, novel cognitive systems. On the contrary, there are at least eigh...

Variations of the brachial plexus and median nerve relationships with axillary artery may be significant to anatomists, radiologists, anesthesiologists, surgeons. In some cases, coexistence anatomical variations nerves vessels also a source conflict between individual structures, e.g., entrapment neuropathy due atypical (superficial nerve) course artery. The presented report describes coexistin...

AIM To validate the use of longitudinal sections against cross sections using micro-CT for disclosing the topography and location of the apical constriction. METHODOLOGY Seventy extracted human teeth with 117 completely developed roots were micro-CT scanned and reconstructed at a voxel size of 27 μm. The 3DSlicer program was used to navigate the longitudinal sections parallel to the long axis...

In Africa volumetrically minor, mid-plate volcanic rocks of Cenozoic age are concentrated in areas affected by Pan-African (500 _+ 150 Ma) crustal reactivation, and are virtually absent from cratonic areas. We interpret this as indicating that Pan-African areas are underlain by fertile lithospheric mantle and cratons by depleted lithospheric mantle, and propose a model to explain both the distr...

The straightforward but unexpected relationship presented here relates crustal thickness to magma type in the Izu-Ogasawara (Bonin) and Aleutian oceanic arcs. Volcanoes along the southern segment of the Izu-Ogasawara arc and the western Aleutian arc (west of Adak) are underlain by thin crust (10-20 km). In contrast those along the northern segment of the Izu-Ogasawara arc and eastern Aleutian a...

A new method of moiré topography is suggested in which a slit beam is used in a scanning mode to generate moiré fringes. One remarkable feature of this method is that, as opposed to existing shadow and projection types, height differences between two consecutive fringes become constant so that absolute fringe orders need not be identified. This advantage makes it possible to measure three-dimen...

Silymarin production by hairy root culture of Milk thistle (Silybum marianum L. Gaertn) was investigated using Agrobacterium rhizogenes AR15834. Hairy roots were induced by injection or inoculation of explants with A. rhizogenes. One month old hairy roots were dissected from the explants and grown in Murashing and Skoog (MS) liquid medium. Polymerase Chain Reaction (PCR) using the B gene and th...

Warming air temperatures in the Arctic are modifying the rates of thermokarst processes along Alaska’s Arctic Coastal Plain. The Arctic Coastal Plain is dominated by thaw lakes. These kilometer-scale lakes are the most visible surface features in the region, and they provide important habitats for migratory birds. The lakes are formed by thermokarst processes, and are therefore susceptible to c...

This study documents the distribution of Selenium (Se) in the Jurassic-Cretaceous Mist Mountain Formation of southeastern British Columbia and in various materials segregated by the five coal mines in the area. This study is preliminary and will be followed up by more detailed and focused studies. The Mist Mountain Formation, which is part of the Kootenay Group (Table 1), outcrops extensively i...
