| Formed artifacts are a broadly defined category including items ranging from tested raw material to formal bifacial implements. |
|
| The primary vascular system consists of a eustele and a bifacial vascular cambium. |
|
| Secondary manoxylic wood is produced by a bifacial vascular cambium and surrounds each vascular strand. |
|
| It possessed secondary xylem and secondary phloem, which were produced by a bifacial vascular cambium with ray and fusiform initials. |
|
| Hence, when Smoky Hill jasper is present in substantial amounts in a collection, the bifacial knives are made primarily from it. |
|
| This small-tool tradition excludes the better-known large bifacial tools of this period and all core tools. |
|
| What he did find at the workshops were hammer stones, blocked-out bifaces, thinned bifacial blanks, and bladelet cores and bladelets. |
|
| Lest any reader miss the point, a depiction of the bifacial god appears throughout the book. |
|
| A bifacial vascular cambium forming manoxylic secondary wood is also present. |
|
| Populations could have experimented with bifacial working many times before it took hold more widely around 1.6m years ago. |
|
| Thanks to NiMh rechargeable batteries, the new µTAB 20 displayboards in both monofacial and bifacial versions have an autonomy of over 30 hours. |
|
| The material culture essentially consists of bifacial tools shaped by core reduction of large blocks or cobbles. |
|
| This was a large surface concentration of armatures with bifacial retouch of quartzitic sandstone, comparable to the Neolithic facies of Tilemsi. |
|
| With scant regard for the convention of the stretcher as support, Farber's paintings are conceived as bifacial and may be installed recto or verso. |
|
| Stone tools of the tradition include triangular points made on flakes, racloirs, triangular bifacial handaxes, and burins and awls made on blades. |
|
| Their internal stem structure is characterized by a eustele with endarch protoxylem, where a small amount of manoxylic wood is produced from a bifacial vascular cambium. |
|
| The Mund assemblage, on the other hand, contained no blades, and tools generally were sparse, consisting mostly of manuported hafted bifaces and bifacial scraper fragments. |
|
| A bifacial cutting implement emerged, called a hand axe, that had longer, straighter, sharper edges than the earlier chopper. |
|
| The most characteristic Lupemban tool is an elongate, lanceolate bifacial point that is often very finely and beautifully flaked. |
|
| The bifacial grooves probably permitted the points to be fastened to a wooden spear or dart. |
|
|
|
| These pre-Clovis projectile points were also bifacial but not as large and well turned as the later technology. |
|
| This rock was especially used for bifacial points. |
|
| It should also be stressed that all the members of Astereae had amphistomatic bifacial leaves with striated cuticles, while striae were absent in all members of Gnaphalieae. |
|
| The characteristic tools are made on flakes produced by a developed Levalloisian technique, including slender unifacial and bifacial lances or spear points for stabbing or throwing. |
|
| Profile bright signs for mono and bifacial. |
|
| It shows entire bifacial knapping, with removals all over the surface. |
|
| We recovered finely made, bifacial point fragments from the archaeological layers, which identified the layer as Solutrean, a cultural phase known from other sites in the region to date between 20,000 and 18,000 years ago. |
|
| A hand axe is made by chipping stone, generally flint, to form a bifacial edge, or wedge. |
|
| Final Process Identification Document for bifacial solar cells. |
|
| Cores with bifacial and multiracial flake removal reflect core rotation, while those with unifacial flake removal indicate flaking from one direction. |
|
| The latter stage of this industry may have had bifacial points. |
|
| The Solutrean has relatively finely worked, bifacial points made with lithic reduction percussion and pressure flaking rather than cruder flintknapping. |
|
| The Clovis point is bifacial and typically fluted on both sides. |
|
| In addition, the QSE will produce Bifacial modules which has the ability to produce additional energy from the back side of the module using reflected sun rays. |
|
| Bifacial fluting describes blades on which this feature appears on both its sides. |
