Borehole tube sampling is a key process of geotechnical engineering. The paper presents numerical analyses smooth in clay using the particle finite-element method. soil described by conventional elasto-plastic constitutive model (Tresca plasticity and quasi-incompressible elastic law). sampler advanced several diameters into until steady state observed. solution for round-tipped clearly identif...
The construction and operation of buildings structures suggest taking measurements to determine accurate dimensions, shape, mutual location all structural elements. This is one the most popular surveying services. All types outlines (lineal, curvilinear, bevelled) surfaces in both plan elevation are subject dimensioning. Depending on goals that set during measuring activities, measurement activ...
In this investigation we detail the results of a systematic analysis worked animal bone from Ulucak, one earliest Neolithic sites in western Anatolia. The collection exhibits wide range types, including points, needles, spatulas, bevelled tools, perforated objects, and other unique objects. A study raw material shows preference for sheep goat long bones, while large-sized rib bones were also ut...
In-situ aeroengine maintenance works are highly beneficial as it can significantly reduce the current cycle which is extensive and costly due to disassembly requirement of engines from aircraft. However, navigating in/out via inspection ports performing multi-axis movements with end-effectors in constrained environments (e.g. combustion chamber) fairly challenging. A novel extra-slender (diamet...
The phase and the ceramic materials that, in Southern Mesopotamia, go under label of “Uruk” (after toponym site southern Iraq) have traditionally been considered origin for development potter’s wheel Near East, according to a perspective that associated emergence wheel, “mass” production so-called bevelled-rim bowls first urbanization. According recent excavations studies it is now clear this w...
Abstract The Mesolithic settlements on the left bank of Danube in Iron Gates have yielded numerous artefacts made osseous materials. Products and sub-products chaîne opératoire are present, suggesting situ manufacturing finished items. Among a restricted range artefact types, most characteristic ones bevelled tools antler, pointed bone, boar tusk scrapers. Our research has focused identifying b...
Two new and three known species of the genera Aponema Jensen, 1978, Molgolaimus Ditlevsen, 1921, Sabatieria Rouville, 1903, and Terschellingia De Mann, 1888 were found at the deep-sea Håkon Mosby Mud Volcano, at a depth of 1250m, in the Norwegian Sea. Aponema ninae sp. n. is characterized by short body length, short spicules, gubernaculum with wide apophyses, which are bevelled on the top, and ...
BACKGROUND Although footwear has been linked to falls in older people, it remains unclear as to which shoe features are beneficial or detrimental to balance in older people. OBJECTIVE To systematically investigate how footwear features affect balance and stepping in older people. METHODS 29 community-dwelling people (mean (SD) age, 79.1 (3.7) years) undertook tests of postural sway, maximal...
A regular stainless steel needle, 1 cm. long, with a sharp and short bevelled point (A) perforates the cornea (or sclera) while the fingers press the rubber bulb (E) and close the vent (D) which connects the glass (pyrex) bulb (C) with the atmosphere. By gradually releasing that pressure, the ocular fluid under examination (aqueous or vitreous) fills the reservoir (B) when the vent is opened in...
The writer, in sputtering a large number of mirrors, has found that the apparatus and methods to be described have several advantages, particularly where very large and perfect mirrors are desired. The accompanying diagram will be self explanatory, and the dimensions given have been found convenient for mirrors up to 10 cm diameter. The apparatus has been designed to avoid the use of any grease...
