E Minor
E minor is a minor scale based on E, consisting of the pitches E, F, G, A, B, C, and D. Its key signature has one sharp, on the F. Its relative major is G major and its parallel major is E major. The E natural minor scale is: Changes needed for the melodic and harmonic versions of the scale are written in with accidentals as necessary. The E harmonic minor and melodic minor scales are: Much of the classical guitar repertoire is in E minor, as this is a very natural key for the instrument. In standard tuning (E A D G B E), four of the instrument's six open (un fretted) strings are part of the tonic chord. The key of E minor is also popular in heavy metal music, as its tonic is the lowest note on a standard-tuned guitar. Scale degree chords The scale degree chords of E minor are: * Tonic – E minor * Supertonic – F-sharp diminished * Mediant – G major * Subdominant – A minor * Dominant – B minor * Submediant – C major * Subtonic – D major Nota ...

Spivak Pronoun
The Spivak pronouns 'e/em/eir' are a set of gender-neutral pronouns in English promoted on the virtual community ''LambdaMOO'' based on pronouns used in a book by American mathematician Michael Spivak. Though not in widespread use, they have been employed in writing for gender-neutral language by those who wish to avoid the standard terms ''he'', ''she'', or singular ''they''. History The precise history of the Spivak pronouns is unclear, since they appear to have been independently created multiple times. The first recorded use of the pronouns was in a January 1890 editorial by James Rogers, who derives ''e'', ''es'', and ''em'' from ''he'' and ''them'' in response to the proposed ''thon''.Rogers, James "That Impersonal Pronoun."

End Of Medium
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received. C0 codes are the range 00 HEX–1FHEX and the default C0 set was originally defined in ISO 646 (ASCII). C1 codes are the range 80HEX–9FHEX and the default C1 set was originally defined in ECMA-48 (harmonized later with ISO 6429). The ISO/IEC 2022 system of specifying control and graphic characters allows other C0 and C1 sets to be available for specialized applications, but they are rarely used. C0 controls ASCII defines 32 control characters, plus the DEL character. This large number of codes was desirable at the time, as multi-byte controls would require implementation of a state machine in the terminal, which was very difficult with contemporary electro ...

HTML Element
An HTML element is a type of HTML (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others). The first used version of HTML was written by Tim Berners-Lee in 1993 and there have since been many versions of HTML. The current de facto standard is governed by the industry group WHATWG and is known as the HTML Living Standard. An HTML document is composed of a tree of simple HTML nodes, such as text nodes, and HTML elements, which add semantics and formatting to parts of a document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed hyperlinks and images). Each element can have HTML attributes specified. Elements can also have content, including other elements and text. Concepts Elements vs. tags As is generally understood, the position of an element is indicated as spanning from a start tag and is terminated by an end tag. This is the case for many, but not all, elem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Membrane Potential
Membrane potential (also transmembrane potential or membrane voltage) is the difference in electric potential between the interior and the exterior of a biological cell. It equals the interior potential minus the exterior potential. This is the energy (i.e. work) per charge which is required to move a (very small) positive charge at constant velocity across the cell membrane from the exterior to the interior. (If the charge is allowed to change velocity, the change of kinetic energy and production of radiation must be taken into account.) Typical values of membrane potential, normally given in units of milli volts and denoted as mV, range from −80 mV to −40 mV. For such typical negative membrane potentials, positive work is required to move a positive charge from the interior to the exterior. However, thermal kinetic energy allows ions to overcome the potential difference. For a selectively permeable membrane, this permits a net flow against the gradient. This is a kind ...

Extracellular Matrix
In biology, the extracellular matrix (ECM), also called intercellular matrix (ICM), is a network consisting of extracellular macromolecules and minerals, such as collagen, enzymes, glycoproteins and hydroxyapatite that provide structural and biochemical support to surrounding cells. Because multicellularity evolved independently in different multicellular lineages, the composition of ECM varies between multicellular structures; however, cell adhesion, cell-to-cell communication and differentiation are common functions of the ECM. The animal extracellular matrix includes the interstitial matrix and the basement membrane. Interstitial matrix is present between various animal cells (i.e., in the intercellular spaces). Gels of polysaccharides and fibrous proteins fill the interstitial space and act as a compression buffer against the stress placed on the ECM. Basement membranes are sheet-like depositions of ECM on which various epithelial cells rest. Each type of connective tissue ...

Effective Microorganism
Effective microorganisms (EM) are various blends of common predominantly anaerobic microorganisms in a carbohydrate-rich liquid carrier substrate (molasses nutrient solution) of ''EM Research Organization, Inc.''''Effective Microorganisms'' ''EM'' and ''EM・1'' are the trademarks of Em Research Organization, Inc., Uruma City, Okinawa, Japan. Many of the so-called " pit additives" used for improving the performance of sanitation systems, namely pit latrines, septic tanks and wastewater treatment plants, are also based on EM. Despite the claims made by manufacturers, available studies which have used scientific methods to investigate these additives have come to the conclusion that long-term beneficial effects are not proven. Studies have stated that effective microorganisms (EM-A, EM-Bokashi) show no effect on yield and soil microbiology in field experiments as bio-fertilizer in organic farming.

Environmental Management
Environmental resource management or environmental management is the management of the interaction and impact of human societies on the environment. It is not, as the phrase might suggest, the management of the environment itself. Environmental resources management aims to ensure that ecosystem services are protected and maintained for future human generations, and also maintain ecosystem integrity through considering ethical, economic, and scientific ( ecological) variables. Environmental resource management tries to identify factors between meeting needs and protecting resources. It is thus linked to environmental protection, resource management, sustainability, integrated landscape management, natural resource management, fisheries management, forest management, wildlife management, environmental management systems, and others. Significance Environmental resource management is an issue of increasing concern, as reflected in its prevalence in several texts inf ...

Energy Management
Energy management includes planning and operation of energy production and energy consumption units as well as energy distribution and storage. Energy management is performed via Energy Management Systems (EMS), which are designed with hardware and software components to implement the tasks. Energy Management can be classified into Building Energy Management, Grid-scale Energy Management (including Grid energy storage), and Marine Energy Management. Energy management objectives are resource conservation, climate protection and cost savings, while the users have permanent access to the energy they need. It is connected closely to environmental management, production management, logistics and other established business functions. The VDI-Guideline 4602 released a definition which includes the economic dimension: "Energy management is the proactive, organized and systematic coordination of procurement, conversion, distribution and use of energy to meet the requirements, ta ...

Emergency Management
Emergency management (also Disaster management) is a science and a system charged with creating the framework within which communities reduce vulnerability to hazards and cope with disasters. Emergency management, despite its name, does not actually focus on the management of emergencies; emergencies can be understood as minor events with limited impacts and are managed through the day-to-day functions of a community. Instead, emergency management focuses on the management of disasters, which are events that produce more impacts than a community can handle on its own. The management of disasters tends to require some combination of activity from individuals and households, organizations, local, and/or higher levels of government. Although many different terminologies exist globally, the activities of emergency management can be generally categorized into preparedness, response, mitigation, and recovery, although other terms such as disaster risk reduction and prevention are also ...
