Infiltration (hydrology)
Infiltration is the process by which water on the ground surface enters the soil. It is commonly used in both hydrology and soil sciences. The infiltration capacity is defined as the maximum rate of infiltration. It is most often measured in meters per day but can also be measured in other units of distance over time if necessary. The infiltration capacity decreases as the soil moisture content of soils surface layers increases. If the precipitation rate exceeds the infiltration rate, Surface runoff, runoff will usually occur unless there is some physical barrier. Infiltrometers, parameters and rainfall simulators are all devices that can be used to measure infiltration rates. Infiltration is caused by multiple factors including; gravity, capillary forces, adsorption, and osmosis. Many soil characteristics can also play a role in determining the rate at which infiltration occurs. Factors that affect infiltration Precipitation Precipitation can impact infiltration in ma ...

Infiltration (HVAC)
Infiltration is the unintentional or accidental introduction of outside air into a building, typically through cracks in the building envelope and through use of doors for passage. Infiltration is sometimes called air leakage. The leakage of room air out of a building, intentionally or not, is called exfiltration. Infiltration is caused by wind, negative pressurization of the building, and by air buoyancy forces known commonly as the stack effect. Infiltration measures The infiltration rate is the volumetric flow rate of outside air into a building, typically in cubic feet per minute (CFM) or liters per second (LPS). The air exchange rate, (''I''), is the number of interior volume air changes that occur per hour, and has units of 1/h. The air exchange rate is also known as air changes per hour (''ACH''). ACH is the hourly ventilation rate, divided by the building volume. It can be calculated by multiplying the building's CFM by 60, and then dividing by the building volume. ...

Infiltration (medical)
Infiltration in a medical context is the process of cells or substances moving across a barrier, typically a tissue barrier, into a place they are not normally found, or in which they are typically found in lower concentrations. Infiltration may refer to normal physiological processes, such as the infiltration of certain immune cells into peripheral tissues. Infiltration may also refer to pathological processes, such as malignant tumor cells infiltrating new areas of the human body, or small particles infiltrating tissues, where they may cause damage or inflammation. Types of Infiltration The term 'infiltration' is frequently used to describe various pathologic and physiologic processes, including but not limited to: Immune Infiltration This occurs when immune cells like lymphocytes and macrophages migrate into tissues in response to infection, injury, or inflammation, aiding in defense and healing but potentially contributing to autoimmune diseases if misdirected. Immune ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infiltration/Inflow
Infiltration and inflow (I/I or I&I) is the process of groundwater, or water from sources other than domestic wastewater, entering sanitary sewers. I/I causes dilution in sanitary sewers, which decreases the efficiency of treatment, and may cause sewage volumes to exceed design capacity. Although inflow is technically different from infiltration, it may be difficult to determine which is causing dilution problems in inaccessible sewers. The United States Environmental Protection Agency considers infiltration and inflow to be combined contributions from both.U.S. Environmental Protection Agency (EPA), Washington, D.C.

The Bad Batch)
''The'' is a grammatical article in English, denoting nouns that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pronoun ''thee' ...

Entryism
Entryism (also called entrism, enterism, infiltration, a French Turn, boring from within, or boring-from-within) is a political strategy in which an organization or state encourages its members or supporters to join another, usually larger, organization in an attempt to expand influence and expand their ideas and program. If the organization being "entered" is hostile to entryism, the entryists may engage in a degree of subterfuge and subversion to hide the fact that they are an organization in their own right. Socialist entryism "Boring from within" One entryist strategy that took place in the United States is called the "boring from within" strategy. Radical workers would join established (and often conservative) trade unions and attempt to join their leadership to shift their stances leftward. These workers were called "borers". Boring was opposed by radical workers who supported dual unionism, where radical unions would attempt to win over workers and firm-level union lo ...

Espionage
Espionage, spying, or intelligence gathering, as a subfield of the intelligence field, is the act of obtaining secret or confidential information ( intelligence). A person who commits espionage on a mission-specific contract is called an ''espionage agent'' or ''spy''. A person who commits espionage as a fully employed officer of a government is called an intelligence officer. Any individual or spy ring (a cooperating group of spies), in the service of a government, company, criminal organization, or independent operation, can commit espionage. The practice is clandestine, as it is by definition unwelcome. In some circumstances, it may be a legal tool of law enforcement and in others, it may be illegal and punishable by law. Espionage is often part of an institutional effort by a government or commercial concern. However, the term tends to be associated with state spying on potential or actual enemies for military purposes. Spying involving corporations is known as c ...

Double Agent
In the field of counterintelligence, a double agent is an employee of a secret intelligence service for one country, whose primary purpose is to spy on a target organization of another country, but who is now spying on their own country's organization for the target organization. Double agentry may be practiced by spies of the target organization who infiltrate the controlling organization or may result from the ''turning'' (switching sides) of previously loyal agents of the controlling organization by the target. The threat of execution is the most common method of turning a captured agent (working for an intelligence service) into a double agent (working for a foreign intelligence service) or a double agent into a ''re-doubled agent''. It is unlike a Defection, defector, who is not considered an agent as agents are in place to function for an intelligence service and defectors are not, but some consider that defectors in place are agents until they have defected. Double agent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infiltration Tactics
In warfare, infiltration tactics involve small independent light infantry forces advancing into enemy rear areas, bypassing enemy frontline strongpoints, possibly isolating them for attack by follow-up troops with heavier weapons. Soldiers take the initiative to identify enemy weak points and choose their own routes, targets, moments and methods of attack; this requires a high degree of skill and training, and can be supplemented by special equipment and weaponry to give them more local combat options. Forms of these infantry tactics were used by skirmishers and irregulars dating back to classical antiquity, but only as a defensive or secondary tactic; decisive battlefield victories were achieved by shock combat tactics with heavy infantry or heavy cavalry, typically charging '' en masse'' against the primary force of the opponent. By the time of early modern warfare, defensive firepower made this tactic increasingly costly. When trench warfare developed to its heigh ...

Urban Exploration
Urban exploration (often shortened as UE, urbex, and sometimes known as roof and tunnel hacking) is the exploration of manmade structures, usually abandoned ruins or hidden components of the manmade environment. Photography and historical interest/documentation are heavily featured in the hobby, sometimes involving trespassing onto private property. Urban exploration is also called draining (a specific form of urban exploration where storm drains or sewers are explored), urban spelunking, urban rock climbing, urban caving, building hacking, or Mouse-holing, mousing. The activity presents various risks, including physical danger, the possibility of arrest and punishment if done illegally and/or without permission, and the risk of encountering Squatting, squatters. Some activities associated with urban exploration may violate local or regional laws, certain broadly interpreted Anti-terrorism legislation, anti-terrorism laws, or can be considered trespassing or invasion of privacy ...
