The chapter analyzes the system of focus-sensitive particles in Vietnamese. EVEN/ ALSO/ONLY foci are discussed across syntactic categories, and Vietnamese is found to organize its system of focus-sensitive particles along three dimensions of classification: (i) EVEN vs. ALSO vs. ONLY; (ii) particles c-commanding foci vs. particles c-commanding backgrounds; (iii) adverbial focus-sensitive partic...
Gelled propellants are improved propellants that can be considered as the final extension of liquid propellants. High specific impulse, good density and safety better than that of both solid and liquid propellants are advantages of the gel propellants. They are made by addition a suitable gellant to liquid propellants. In this research, nano Al particles have been used in UDMH gel fuel. The gel...
The Run I results on the searches for new physics in photon final states were intriguing. The rare eeγγ 6ET candidate event and the measured event rate for the signature l + γ + 6ET, which was 2.7 sigma above the Standard Model predictions, sparked signature-based searches in the γγ +X and lγ +X channels. With more data in Run II we should be able to answer a simple question: was it an anomaly ...
The degree of shrinkage of particle stabilised bubbles of various sizes, in a polydisperse bubble dispersion, has been investigated in the light of the finite adsorption times for the particles and the disproportionation kinetics of the bubbles. For the case where the system contains an abundance of particles we find a threshold radius, above which bubbles are stabilised without any significant...
Particulate separation has many applications in medicine, biology and industry. In this research, the separation of polystyrene particles with a diameter of 10, 20 and 30 μm in the fluid flow of a microchannel is investigated. The microchannel consists of a spiral region and a straight region under the influence of acoustic waves. In the spiral region, the particles under hydrodynamic effects u...
Hydroxyapatite (HA), which is represented by the formula Ca10(PO4)6(OH)2, is one of the inorganic components of the hard tissues of living bodies such as bones, teeth, etc. HA is a calcium phosphate-based bioceramic, which has been used in medicine and dentistry for more than 20 years because of its excellent biocompatibility with human tissues. The precipitation process, considered here, ...
در سالهای اخیر تلاش زیادی برای سنتز کمپلکس های سوپرامولکول و پلیمرهای کوئوردیناسیونی بر مبنای لیگاندهای آلی چند دندانه شده است. این مواد به دلیل داشتن خواص منحصر به فرد، کاربردهای زیادی در صنعت دارند. سنتز پلیمرهای کوئوردیناسیونی جدید از سرب(ii) در ابعاد بالک(توده) و نانو با استفاده از روش گرادیان دمایی و به روش شاخه جانبی صورت گرفته و با روش طیف سنجی ir و پایداری گرمایی آن ها توسط آنالیزهای وز...
The pinning effect of small incoherent particles on grain growth in two-dimensional polycrystalline systems has been simulated using a phase field model. Simulations were performed for different sizes and area fractions of the second-phase particles and for two types of initial microstructure and different initial grain sizes. The grain size distribution and the number of particles located at g...
