Economics (/ ɛ k ə ˈ n ɒ m ɪ k s, iː k ə-/) is the social science that studies the production, distribution, and consumption of goods and services.. Economics focuses on the behaviour and interactions of economic agents and how economies work. Microeconomics analyzes basic elements in the economy, including individual agents and markets, their interactions, and the outcomes of interactions.

Aggregate Impact Values, (AIV's), below 10 are regarded as strong, and AIV's above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Aggregate Impact Value; Test Specifications:

In order to obtain the relationship between fractal dimension and energy dissipation of rock-like materials under initial stress state, a variable cross-section split Hopkinson pressure bar (SHPB) test system with active confining pressure loading device was used to carry out impact compression and splitting tests on cemented sand specimens. The impact test results show …

Calculation of particle (aggregate) size spectrum as in Kriest (2002; porous scenario). Note that high values of spectral exponent (" ε " of Kriest, 2002 ) indicate "steep" size spectra or a large proportion of small particles, while low values indicate "flat" spectra, corresponding to a prevalence of large particles.

In order to answer that question, we need to better understand the relationship between inflation, GDP and unemployment rate. GDP Trend. Historical data suggests that annual GDP growth in excess of 2.5% will caused a 0.5% drop in unemployment rate for every percentage point of GDP over 2.5%. It sounds like the perfect way to kill two birds with ...

The values for μ should be less than enough to develop the convergence rate . The effect of variables μ on the load-deformation response was detected to be important as illustrated in Fig. 8(b). The value of 0.0048 for μ portrayed a good estimate with the experimental results. To prevent the incoherence in the spreading of stresses and ...

The real GDP formula that more accurately reflects economic growth or decline is as follows: Real GDP = Nominal GDP / Deflator. In a fictional scenario, this means that if the nominal GDP is $250 million and the interest rate is 2%, you would calculate real GDP this way: 250 million / 1.02 = 245.01 million. In this scenario, factoring inflation ...

The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. It is the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the ...
