As noted earlier, chiral compounds synthesized from achiral starting materials and reagents are generally racemic (i.e. a 50:50 mixture of enantiomers). Separation of racemates into their component enantiomers is a process called resolution. Since enantiomers have identical physical properties, such as solubility and melting point, resolution ...

Liquid-solid separation involves the separation of two phases, solid and liquid, from a suspension. It is used in many processes for the: 1. recovery of valuable solid component (the liquid being discarded); 2. liquid recovery (the solids being discarded); 3. recovery of both solid and liquid; or 4. recovery of neither phase (e.g., when a liquid is …
This is referred to as a boundary layer separation or flow separation. Downstream of the separation point, vortices often form, resulting in a turbulent flow. A flow separation is particularly dangerous on the wings of an aircraft, as this also causes a loss of lift and the aircraft is in danger of crashing.
Life stresses or loss that result in separation. Examples include the illness or death of a loved one, loss of a beloved pet, divorce of parents, or moving or going away to school. Family history. Having blood relatives who have anxiety symptoms or an anxiety disorder may increase the risk of having separation anxiety disorder.

Separation anxiety is a universal phase of human development that typically emerges at or before 1 year of age, peaks between 9 to 18 months, and phases out by approximately 2.5 years. The re-emergence of transient separation anxiety is common in children when they enter school for the first time, which may be considered a …
Zirconium has drawn in a special consideration in medical fields and industrial applications due to its biocompatibility and the needed mechanical and biological properties. Consequently, the separation and accurate determination of the zirconium …
The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.It is a measure of a substance's ability to transfer heat through a material by conduction.Note that Fourier's law applies for all matter, regardless of its state (solid, liquid, or gas), therefore, it is also defined for liquids and …
A separation is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one of the results of the separation is a supplement in one or more of the source mixture's constituents. In some cases, a separation process may fully divide the mixture into its pure constituents.

A Separation Agreement is a document that two people in a marriage use to divide their assets and responsibilities while they are separated. Some spouses separate temporarily and eventually reconcile, while others separate indefinitely. In many cases, spouses separate as a step towards divorce.. If you and your spouse pursue a divorce, …

Separation of Variables. The heat equation is linear as (u) and its derivatives do not appear to any powers or in any functions. Thus the principle of superposition still applies for the heat equation (without side conditions). If (u_1) and (u_2) are solutions and (c_1,c_2) are constants, then ( u= c_1u_1+c_2u_2) is also a …
