Electrostatic separation uses charges to separate crushed material particles, commonly used in ore sorting to remove valuable or foreign material. Conducting particles attach to oppositely charged objects, while repulsive force changes the trajectory of falling objects. Electrostatic charges can be positive or negative, and can build up from friction. Electrostatic separation is a preferred method […]
Gravity separation separates suspensions by density and size. It is used in medicine and metallurgy. The most common methods are static separation, centrifugation, and jigging. Particle size and water balance are important for efficient separation. Centrifugation is commonly used in medicine, while jigging is an older but effective technique. Gravity separation is a method of […]
Foam separation uses a bubbled gas and surfactant to remove components from liquid mixtures. It can be used to extract precious metals, proteins, and impurities from water. Foam separation can be performed as batch or continuous operations and is used in wastewater treatment systems. Foam separation is a process of removing a component of a […]
Magnetic separation is used in industry to recover ferromagnetic contaminants, extract useful metals, purify materials, and more. Equipment manufacturers offer various products for different applications, with different sizes and strengths of magnetic fields. The process involves a rotating drum that creates a magnetic field, attracting sensitive particles while non-magnetic materials fall through. Magnetic separation can […]
Source separation technology is important for hearing aids to distinguish different noises in crowded environments. Poor programming can lead to discomfort and people turning off their aids. Speech recognition and music recording also use source separation algorithms. Source separation is the distinction of multiple sources in a signal to allow one or more to be […]
The separation theorem assumes that every business owner aims to maximize the value of their business, but in reality, entrepreneurs may have different goals. It is used for market-wide calculations and theories, but not for individual company decisions. The theorem is named after economist Irving Fisher. The separation theorem is a principle used in economics. […]
The US Constitution’s First Amendment prohibits Congress from establishing a religion or prohibiting its free exercise. The Civil Rights Act of 1964 extended this to prohibit discrimination based on religion. However, the separation of church and state remains a contentious issue, with lawsuits against government agencies endorsing specific religions. While the US government is not […]
Separation of powers distributes power among different groups or individuals in a government. The US Constitution institutionalized this by creating three branches of government and sharing power between federal and state governments to prevent abuse of power. Separation of powers refers to a system of government where power is not centralized in one person or […]
Separation anxiety is common in children under six when separated from a caregiver, but if it persists after six it may be a disorder. Trauma, overprotective parents, and moving frequently can cause separation anxiety. It can also be a learned behavior or a biological disposition. Separation anxiety is characterized by irrational feelings of worry or […]
Slope separation uses tunnels, ramps, bridges, and interchanges to separate roads or rails at different elevations. It improves traffic flow and reduces accidents, but can be unsightly and expensive. Level separation is a process used to improve traffic flow at intersections and junctions. With slope separation design, each road or rail surface is placed at […]
The umbilical cord connects the fetus to the mother’s placenta and is cut after birth, with a small portion remaining attached to the baby’s belly button. Factors that could delay separation include antiseptics, immunodeficiencies, cesarean section, prematurity, and neonatal sepsis. Keeping the cord clean and dry is important to prevent infection. Premature babies have a […]
Couples considering separation should weigh the benefits of filing a legal separation petition, which can provide financial and legal protection, against the possibility of reconciliation. Legal requirements vary by jurisdiction, and legal advice is recommended to determine the best course of action. When a married couple chooses to separate, there is always the question of […]
Common law separation is when unmarried couples who have lived together decide to separate. Assets are divided based on what each person brought into the relationship, and common property is often divided equally. Child support is likely, but spousal support may not be awarded. Custody and support arrangements for children are usually worked out outside […]
Chemical engineering uses separation processes such as distillation, evaporation, and crystallization to extract components with higher purity. Engineers design new processes for each project, such as boiling fermented fruit mixture for alcohol distillation or using evaporation to separate solids from fluids. Crystallization is used in the pharmaceutical industry, while waste removal uses flotation and liquid-liquid […]
A carefully defined termination policy can help end the employer/employee relationship smoothly. To create a severance policy, identify the purpose and goals, and write a consistent policy that covers legal issues and doesn’t discriminate. Seek legal advice and senior management approval before distributing the policy to employees. The employer/employee relationship can end smoothly with a […]
Membrane separation is a process used to filter substances from a mixture through a porous membrane. It has practical applications in water filtration and creating concentrated solutions. The main types of membrane separation are reverse osmosis, nanofiltration, ultrafiltration, and microfiltration. The texture and chemical composition of the membrane determine which materials pass through it. Membrane […]
Disaggregation is breaking down complex components into smaller ones to make managing resources easier. Separation is the opposite of bundling, and can be used in business for commission calculation, multinational fund transfers, investments, and telecommunication services. Separation makes tasks easier and saves money. In business, disaggregation is a term that is applied to any situation […]
