Environmental Engineering
Environmental engineering is a professional engineering discipline that encompasses broad scientific topics like chemistry, biology, ecology, geology, hydraulics, hydrology, microbiology, and mathematics to create solutions that will protect and also improve the health of living organisms and improve the quality of the environment. Environmental engineering is a sub-discipline of civil engineering and chemical engineering. While on the part of civil engineering, the Environmental Engineering is focused mainly on Sanitary Engineering. Environmental engineering is the application of scientific and engineering principles to improve and maintain the environment to: * protect human health, *protect nature's beneficial ecosystems, *and improve environmental-related enhancement of the quality of human life. Environmental engineers devise solutions for wastewater management, water and air pollution control, recycling, waste disposal, and public health. They design municipal water supply ...

Langmuir Equation
The Langmuir adsorption model explains adsorption by assuming an adsorbate behaves as an ideal gas at isothermal conditions. According to the model, adsorption and desorption are reversible processes. This model even explains the effect of pressure i.e at these conditions the adsorbate's partial pressure, p_A, is related to the volume of it, , adsorbed onto a solid adsorbent. The adsorbent, as indicated in the figure, is assumed to be an ideal solid surface composed of a series of distinct sites capable of binding the adsorbate. The adsorbate binding is treated as a chemical reaction between the adsorbate gaseous molecule A_\text and an empty sorption site, . This reaction yields an adsorbed species A_\text with an associated equilibrium constant K_\text: : A_ + S A_ From these basic hypotheses the mathematical formulation of the Langmuir adsorption isotherm can be derived in various independent and complementary ways: by the kinetics, the thermodynamics, and the statistical ...

Lane–Emden Equation
In astrophysics, the Lane–Emden equation is a dimensionless form of Poisson's equation for the gravitational potential of a Newtonian self-gravitating, spherically symmetric, polytropic fluid. It is named after astrophysicists Jonathan Homer Lane and Robert Emden. The equation reads : \frac \frac \left(\right) + \theta^n = 0, where \xi is a dimensionless radius and \theta is related to the density, and thus the pressure, by \rho=\rho_c\theta^n for central density \rho_c. The index n is the polytropic index that appears in the polytropic equation of state, : P = K \rho^\, where P and \rho are the pressure and density, respectively, and K is a constant of proportionality. The standard boundary conditions are \theta(0)=1 and \theta'(0)=0. Solutions thus describe the run of pressure and density with radius and are known as ''polytropes'' of index n. If an isothermal fluid (polytropic index tends to infinity) is used instead of a polytropic fluid, one obtains the Emden–Chan ...

Ivey's Equation
Ivey's (J.B. Ivey & Company), a former department store chain, was acquired by Dillard's, Inc. in 1990. Ivey's was based in Charlotte, North Carolina, and was founded in 1900 by Joseph Benjamin (J. B.) Ivey. History J. B. Ivey opened the first Ivey's store on February 19, 1900, on North Tryon Street in Charlotte, North Carolina. The initial location, "one and half blocks from the town square," resulted in poor sales. Later in 1900, Ivey moved the store location to the first block of West Trade Street. The business grew and relocated to 13 North Tryon Street in fall 1914. George M. Ivey, J. B. Ivey's only son, joined the company in 1920 and moved to convert the firm from a partnership to a corporation, which was completed in 1922. The company built a new store in Charlotte in 1924, which remained the only Ivey's store until 1935. Ivey's opened a store in Greenville, South Carolina, in 1935, and in Asheville, North Carolina, in 1937. Ivey's became a publicly-traded corporation in th ...

Falkner–Skan Boundary Layer
In fluid dynamics, the Falkner–Skan boundary layer (named after V. M. Falkner and Sylvia W. Skan) describes the steady two-dimensional laminar boundary layer that forms on a wedge, i.e. flows in which the plate is not parallel to the flow. It is also representative of flow on a flat plate with an imposed pressure gradient along the plate length, a situation often encountered in wind tunnel flow. It is a generalization of the flat plate Blasius boundary layer in which the pressure gradient along the plate is zero. Prandtl's boundary layer equations The basis of the Falkner-Skan approach are the Prandtl boundary layer equations. Ludwig Prandtl simplified the equations for fluid flowing along a wall (wedge) by dividing the flow into two areas: one close to the wall dominated by viscosity, and one outside this near-wall boundary layer region where viscosity can be neglected without significant effects on the solution. This means that about half of the terms in the Navier-Stok ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Emden Equation
Emden () is an independent city and seaport in Lower Saxony in the northwest of Germany, on the river Ems. It is the main city of the region of East Frisia and, in 2011, had a total population of 51,528. History The exact founding date of Emden is unknown, but it has existed at least since the 8th century. Older names for Emden are Setutanda, Amuthon, Embda, Emda, Embden and Embderland. Town privilege and the town's coat of arms, the ''Engelke up de Muer'' (The Little Angel on the Wall) was granted by Emperor Maximilian I in 1495. In the 16th century, Emden briefly became an important centre for the Protestant Reformation under the rule of Countess Anna von Oldenburg who was determined to find a religious "third way" between Lutheranism and Catholicism. In 1542 she invited the Polish noble John Laski (or ''Johannes a Lasco'') to become pastor of a Protestant church at Emden; and for 7 years he continued to spread the new religion around the area of East Frisia. However, in 15 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
