Magnesium borates can be used as detergent compounds or hydrocarbon catalyzers and in the ceramics industry for superconductor material manufacture owing to their high elastic coefficient and resistance to corrosion at high temperatures. In the present study, the synthesis of magnesium borate was facilitated via a novel ultrasonic method of mixing and the identification and characterization of the material were carried out via X-Ray diffraction (XRD), Fourier transform infrared (FT-IR), and Raman spectroscopies, and the B2 O3 content was determined through titration.

The dynamic calculation model of launcher on combat vehicles using hydraulic jacks on elastic ground
In this paper, a dynamics model of a launcher on a combat vehicle using hydraulic jacks is established. Theoretical foundations of multi-object mechanics are used to set up mathematical equations describing the vibration of a launcher when firing. The ground in the surveyed model is considered as an elastic element with K hardness and viscous drag coefficient C

The present paper derives numerical bounds of the elastic properties of polycrystals. The homogenized elastic coefficients are computed from Voronoi-type unit cells. The main result of the article detemines the upper and lower bounds for a case of polycrystals made up of cubic single crystals by using the fast Fourier transform method (FFT) based on the shape function.

The dynamic response to variable magnitude moving distributed masses of simply supported non-uniform Bernoulli–Euler beam resting on Pasternak elastic foundation is investigated in this paper. The problem is governed by fourth order partial differential equation with variable and singular coefficients. The main objective of this work is to obtain closed form solution to this class of dynamical problem.

Chapter 6 - Elasticity. Both the elasticity coefficient and the total revenue test for measuring price elasticity of demand are presented in this chapter. The text discusses the major determinants of price elasticity. The chapter reviews a number of applications and presents empirical estimates for a variety of products. Cross- and income elasticities of demand and price elasticity of supply are also examined. The Last Word is about how firms use price elasticities to set their price.

To study the resource productivity and efficiency in different vegetables, Cobb-Douglas type of production function was fitted. Two firms operating vegetable supply chains in Bengaluru rural district of Karnataka were identified, they were HOPCOMS (Cooperative) and Reliance fresh (Corporate). A sample of 180 farmers was selected using random sampling method and data was collected through personal interview method. Among the different vegetable supply chains major vegetables cultivated were identified by conducting a pilot survey in the study area, two major vegetables viz.

This study has been designed to calculate elasticity and buoyancy and projection of various taxes in Nepal from 2018 to 2020. This study is based on secondary data published by the government of Nepal covering a period between the fiscal year 2000 to 2016. The various sources of revenue as a proportion of the Gross Domestic Product (GDP) have been analyzed during this period. This study particularly deals with the analysis of elasticity and buoyancy of tax and nontax revenue. The projection of tax revenue since 2018 to 2020 has also been forecasted.

Research results on 3D modeling of the diamond grain and its bearing layer when sintering diamond grinding wheels are provided in this paper. The influence of the main characteristics of the wheel materials and the wheel production process, namely the quantity of metallic phase within diamond grain, coefficient of thermal expansion of the metallic phase, the modulus of elasticity of bond material and sintering temperature, on the internal stresses arising in grains is investigated. The results indicate that the stresses in the grains are higher in the areas around the metallic phase.

This study estimates a supply model for apricots and an export demand model for dried apricots for Turkey to provide unit-free measure coefficients for better supply and marketing management. Using parameter estimates from the models and sample average data, elasticities of long-run supply, price-yield and export of dried apricots were computed as 0.72, 0.54 and -0.87 respectively.

In the case of stationary motion, the generalized Ritz's method has been applied to obtain system of linear differential equations with periodic coefficients. We have written computer programs to check conditions of dynamic stability and to find periodic solutions of the obtained equations. Numerical examples are given and from which the effect of elastic factors on articulation reactions is evaluated.

Parametric oscillation of the rectangular thin plate on the elastic foundation with two coefficients1 when making mention of the creep of material, has been investigated in earlier publications (see for example [2, 3]). However forced oscillation of the rectangular thin plate, to the author's knowledge, has not been hitherto examined.
