Algorithms for solving typical mineralogical problems associated with quantitative x-ray spectral analysis and quantitative x-ray phase analysis using the program “Origin” are developed. The calculation of the areas and midpoint of spectral lines using the tabular processor of the program “Origin” is considered. Vario…
Manufacturers are pushed to use superalloys such as titanium alloys in the aerospace part due to environmental and economic issues. The refractory properties of titanium alloys result in rapid and premature wear of the cutting tools, especially by thermal diffusion. Therefore, the purpose of this paper is to focus on…
The quality and depth of content Web of Science offers to researchers, authors, publishers, and institutions sets it apart from other research databases.The inclusion of News of NAS RK.Series of chemistry and technologies in the Emerging Sources Citation Index demonstrates our dedication to providing the most relevant…
Abstract Genomic KRAS alterations are identified in >90% of pancreatic adenocarcinomas (PDA), but there are no efficient targeted therapies for these patients. RAF-MEK-MAPK is frequently cited as a frequent potentiator in RAS-driven malignancies. Directly inhibiting the biochemical output of oncogenic Ras and Raf via…
Designs, and so is fire protection design, are accomplished by several methods. Two basic design methods can be differentiated, one of them is based on descriptive regulation and the other is the engineering method. Both methods have advantages and disadvantages. The complex design tasks can be solved by engineering m…
In hot rolling of ferritic stainless steels, prevention of sticking to rolls is very important from the viewpoint of productivity. However, the formation mechanism of the sticking has not been clarified sufficiently. Therefore, in this work, rolling experiments were carried out using a tribo-simulator. The results cla…
In this study, a rapid oxynitriding technique based on induction-heating was developed for the titanium alloy Ti–6Al–4V, and its effects on surface characteristics of the alloy were investigated. The surface microstructures of the alloy were characterized by employing a scanning electron microscope, electron back-scat…
The development of a numerical method for fissure formation during the carbonization of coke is needed because the formed fissures determine the coke’s particle size. In this study, we proposed and developed a novel numerical method that can represent initiation, extension, and branching of multiple cracks. Fundamenta…
Cast blasting has recently received much attention as a blast technique in strip-mining coal operations. Mines that have tried this approacn have found that in some cases it proved to be advantageous and reduced costs, while in other cases it seemed to present no particular improvement. Thus it is very pertinent to th…
In this work, dot-sized upconversion nanocrystals (UCN-dots) with diameter\nc.a. 3.4-0.15 nm have been synthesized. These UCN-dots exhibit visible emission\n(at 497, 527 and 545 nm) under the excitation with 980 nm CW-NIR laser.\nFurther, these UCN-dots exhibit high energy upconversion emission (UV region,\n206 to 231…
Optimization of Reliability and Cost in Series-Parallel-Repairable Systems with Bathtub-Shaped Failure Rate
Understanding the behavior of entities is critical to the development of new policies and technologies aiming at global health and wellbeing; this paper presents a unified model developed and validated for the deposition of entities, ranging from a few Angstroms to tens of nanometers,on nanofibers. The transport of en…
Effects of the electric field and impurity position on the 2p-excited state self-polarization and binding energy of the electron-impurity in a spherical quantum dot are investigated as a function of the dot radius using variational approach. According to results, turning point of 2p-excited state binding energy change…
We revisit the argument that link the efficiency of a solar cell to its reverse operation as a LED, in the case where the material is organic. In organic cells, exciton transport is an intermediate process between sunlight absorption and the generation of electric current. We show that quenching exciton radiation can…
An assessment and correlation analysis was performed between the main indicators when using the drug etoricoxib for the removal of third molars.
Field data combined with theoretical derivations were used to develop a computer model to design a surface mining operation using explosive casting. Casting results varied from 44 to 65%, depending on bench height. A cost comparison and cash flow analysis with a conventionally mined operation indicated that the castin…
A novel photothermoelectric resistance effect of the Ti/SiO2/Si films induced by 10.6 [Formula: see text]m CO2 laser is discovered and investigated. The transient response of the resistance is observed and analyzed in this work. Under the continuous irradiation of the laser, the thermal resistance value changes with t…
Abstract Inappropriate activation of the oncogenic transcription factor STAT3 is a common finding in breast cancer, in which it is constitutively activated in 70% of all cases and almost all triple negative breast cancers (TNBC). We investigated exploiting this feature of breast cancer for the development of tumor-tar…
Infected root canals contain a variety of microorganisms which include aerobes, anaerobes, and fungus. Root canal teeth are more likely to harbor E. faecalis than primary cases. Mineral Trioxide Aggregate is an endodontic repair material which possesses several advantageous properties such as good sealing property, bi…
