Early Acheulian bifaces appear to be characterized by seven basic operations. After a brief description of each operation, I propose how the pattern of that operation had the capacity to serve as an analogue for a concept of the soul that could be expressed both in self-concept (selfobject) and interpersonal relations (object relations). 1. A 'core' is flaked and the flake is trimmed, in turn, ...

BACKGROUND Class B CpG oligodeoxynucleotides primarily interact with Toll-like receptor 9 (TLR9) in B cells and enhance the immune system through induction of various interleukins including interleukin-6 in these immune cells. Although free class B CpG oligodeoxynucleotides do not induce interferon (IFN)-α production, CpG oligodeoxynucleotide molecules have been reported to induce IFN-α when lo...

Size and shape-selective Sn(MoO4)2 nanomaterials have been synthesized for the first time using a simple hydrothermal route by the reaction of Sn(ii) chloride salt with sodium molybdate in CTAB micellar media under stirring at 60 °C temperature for about three hours. Needle-like and flake-like Sn(MoO4)2 nanomaterials were synthesized by optimizing the CTAB to metal salt molar ratio and by contr...

In this paper, the reasons of damage water pumps parts of the air compressor cooling system were studied. To reach this goal, the works like preparing metallographic samples, evaluation of structure, investigation of mechanical properties, the alloy parts detection and chemical analysis of deposit and corrosion products collected from the parts were performed. According to studies and results o...

A dense and thick flake-like cathode structure was demonstrated to have a preferential crystallographic orientation for Li(+) migration and a better tolerance to cracking, both of which enable a reversible and stable capacity at moderate rates from 0.1 to 2 C.

Flake fractures of the talus are uncommon injuries, usually associated with marked inversion or eversion of’ the foot and ankle, coupled with tearing of the medial [internal laterals or the lateral [fibuiar collateral] ligament or of both ligaments. \Vatson-Jones (1943), relating ninety-seven cases of fracture and fracture-dislocation of the talus and navicular hone in the Royal Air Force in tw...

Efficient visible light-induced photoelectrochemical oxidation of water was achieved using a tungsten(iv) oxide (WO(3)) film composed of perpendicularly oriented plate-like crystallites, a flake-wall film, prepared on a transparent conductive substrate by controlling anisotropic crystal growth of tungsten oxide hydrate (WO(3).H(2)O) followed by calcination.

After advent of graphene as a saturable absorber many experiments have been conducted to produce short pulse duration pulses. Here, we have measured the properties of flake-graphene saturable absorber mirrors of various flake sizes dependent on fabrication technique. These mirrors enabled us to obtain a large mode-locking bandwidth of 16nm in an erbium-doped fiber laser. Mirrors with large flak...
