Abstract:
The finds of giant CLIPPIR-type diamonds in the placers hosted by the Ebelyakh River basin in the north of Yakutia suggest that similar diamonds can be found in the kimberlites of the Anabar region and the nearest northern deposits located within the collisional Khapchan and Daldyn terranes. To predict the discovery of such diamonds, the authors use the 5E diagram method based on the principle of similarity of the compositions of five oxides of satellite minerals (Grt, Cpx, Chr and Ilm) of diamond (DSM) with the reference diagrams for the Karowe pipe (K-6, Botswana) with the composition of tho

Abstract:
The article considers the geochemistry of diamond-associated minerals of the Karowe (Botswana) and Zarnitsa (Russia) weakly diamondiferous pipes – deposits containing high-quality and costly giant CLIPPIR diamonds. There is applied a predictive method for geochemical analogy to the diamond-associated minerals compositions of such pipes, according to a probabilistic geostatistics-based approach (cluster analysis). The methods of 5Е diagrams for four diamond-associated minerals – pyropes, picroilmenites, chromites and chrome diopsides, and 4E diagrams for pyropes can predict large and giant “nat

Abstract:
Three-dimensional temperature (T)–pressure (P)–composition (X) phase diagrams of binary carbon-hydrogen (C–H) and carbon-oxygen (C–O) systems for activated low pressure diamond growth have been calculated. Based on an approximation of linear combination between C–H and C–O systems, a projective ternary carbonhydrogen-oxygen (C–H–O) phase diagram has also been obtained. There is always a diamond growth region in each of these phase diagrams. Once a supply of external activating energy stops, the diamond growth region will not exist.

Abstract:
The patterns of the joint genesis of diamonds, and their paragenetic inclusions under lower-mantle conditions, are controlled by the liquidus melting conditions of the multicomponent diamond-forming system. The boundary compositions of this system are evident from the generalized data produced by the analytical mineralogy of paragenetic inclusions in lower-mantle diamonds. We studied the structure of the liquidus of a theoretical diamond-forming system in a physicochemical experiment with P–T parameters typical of the depths of 670–800 km.

Abstract:
Offline hand-drawn diagram recognition is concerned with digitizing diagrams sketched on paper or whiteboard to enable further editing. Some existing models can identify the individual objects like arrows and symbols, but they become involved in the dilemma of being unable to understand a diagram’s structure. Such a shortage may be inconvenient to digitalization or reconstruction of a diagram from its hand-drawn version. Other methods can accomplish this goal, but they live on stroke temporary information and time-consuming post-processing, which somehow hinders the practicability of these met

Abstract There are ‘a multitude of states of matter’. Materials composed of just one or two types of atoms can form many different states of matter. Each state has qualitatively different physical properties. Transitions between distinct states are tipping points and are defined by abrupt changes in properties. Dramatic examples include superconductivity and superfluidity. Phase diagrams encode which state of a material is stable under specific conditions defined by variables such as temperature and pressure. The phase diagrams of water, carbon dioxide, and carbon are discussed to illustrate k

The changes in the side chains such as tyrosine also can be followed. A self-deconvolution and fitting procedure is presented that allows the determination of both pressure-induced and temperature-induced changes in the secondary structure of proteins.

To measure the properties of lubricant under high pressure, a diamond-anvil pressure cell was employed. With a falling sphere viscometry, viscosities were measured up to 2 GPa at up to 200 °C for traction oils. The results showed linearity between logarithmic viscosity and pressure at any temperatures. At 200 °C, lubricant viscosity-pressure coefficient fell to between 1/4 and 1/3rd of the value at 40°C. A simple expression for the dependence of high pressure viscosity on temperature has been suggested. Pressure temperature phase diagram of liquid-solid transition was plotted from the obtained
