A bifid penis (or double penis) is a rare congenital defect where two genital tubercles develop. [1] [2]

Many species of male marsupials have a naturally bifurcated penis, with left and right prongs that they insert into multiple vaginal canals simultaneously. [3]

Engineering statistics combines engineering and statistics using scientific methods for analyzing data. Engineering statistics involves data concerning manufacturing processes such as: component dimensions, tolerances, type of material, and fabrication process control. There are many methods used in engineering analysis and they are often displayed as histograms to give a visual of the data as opposed to being just numerical. Examples of methods are:

  1. Design of Experiments (DOE) is a methodology for formulating scientific and engineering problems using statistical models. The protocol specifies a randomization procedure for the experiment and specifies the primary data-analysis, particularly in hypothesis testing. In a secondary analysis, the statistical analyst further examines the data to suggest other questions and to help plan future experiments. In engineering applications, the goal is often to optimize a process or product, rather than to subject a scientific hypothesis to test of its predictive adequacy. The use of optimal designs reduces the cost of experimentation.
  2. Quality control and process control use statistics as a tool to manage conformance to specifications of manufacturing processes and their products.
  3. Time and methods engineering use statistics to study repetitive operations in manufacturing in order to set standards and find optimum manufacturing procedures.
  4. Reliability engineering which measures the ability of a system to perform for its intended function and has tools for improving performance.
  5. Probabilistic design involving the use of probability in product and system design
  6. System identification uses statistical methods to build mathematical models of dynamical systems from measured data. System identification also includes the optimal design of experiments for efficiently generating informative data for fitting such models.

Fellatio is an oral sex act involving a person stimulating the penis of another person by using the mouth, throat, or both. Oral stimulation of the scrotum may also be termed fellatio, or colloquially as teabagging. If fellatio is performed on oneself, the act is called autofellatio.

In organic chemistry, a peptide bond is an amide type of covalent chemical bond linking two consecutive alpha-amino acids from C1 of one alpha-amino acid and N2 of another, along a peptide or protein chain.

Persistent genital arousal disorder (PGAD), previously called persistent sexual arousal syndrome, is spontaneous, persistent, unwanted and uncontrollable genital arousal in the absence of sexual stimulation or sexual desire, and is typically not relieved by orgasm. Instead, multiple orgasms over hours or days may be required for relief.

<i>Pisolithus arhizus</i> Species of fungus

Pisolithus arhizus is a widespread earth-ball like fungus, which may in fact be several closely related species. Common names include dead man's foot and dyeball. It is known in Australia as the horse dung fungus, in South Africa as perdebal, and in Europe as the Bohemian truffle. This puffball's black viscous gel is used as a natural dye for clothes. Pisolithus arhizus is a major component in mycorrhizal fungus mixtures that are used in gardening as powerful root stimulators. It is inedible.

Splitting is the failure in a person's thinking to bring together the dichotomy of both perceived positive and negative qualities of something into a cohesive, realistic whole. It is a common defense mechanism wherein the individual tends to think in extremes. This kind of dichotomous interpretation is contrasted by an acknowledgement of certain nuances known as "shades of gray".

<span class="mw-page-title-main">Non-penetrative sex</span> Sexual activity that usually does not include sexual penetration

Non-penetrative sex or outercourse is sexual activity that usually does not include sexual penetration. It generally excludes the penetrative aspects of vaginal, anal, or oral sexual activity, but includes various forms of sexual and non-sexual activity, such as frottage, mutual masturbation, kissing, or cuddling. Some forms of non-penetrative sex, particularly when termed outercourse, include penetrative aspects, such as penetration that may result from forms of fingering or oral sex.

The Association for Scottish Literary Studies (ASLS) is a Scottish educational charity, founded in 1970 to promote and support the teaching, study and writing of Scottish literature. Its founding members included the Scottish literary scholar Matthew McDiarmid (1914–1996). Originally based at the University of Aberdeen, it moved to its current home within the University of Glasgow in 1996. In November 2015, ASLS was allocated £40,000 by the Scottish Government to support its work providing teacher training and classroom resources for schools.

Software Ecosystem is a book written by David G. Messerschmitt and Clemens Szyperski that explains the essence and effects of a "software ecosystem", defined as a set of businesses functioning as a unit and interacting with a shared market for software and services, together with relationships among them. These relationships are frequently underpinned by a common technological platform and operate through the exchange of information, resources, and artifacts.

Cunnilingus is an oral sex act performed by a person on the vulva or vagina of another person. The clitoris is the most sexually sensitive part of the human female genitalia, and its stimulation may result in a woman becoming sexually aroused or achieving orgasm.

Microbial food cultures are live bacteria, yeasts or moulds used in food production. Microbial food cultures carry out the fermentation process in foodstuffs. Used by humans since the Neolithic period fermentation helps to preserve perishable foods and to improve their nutritional and organoleptic qualities. As of 1995, fermented food represented between one quarter and one third of food consumed in Central Europe. More than 260 different species of microbial food culture are identified and described for their beneficial use in fermented food products globally, showing the importance of their use.

Butchie is a fictional character on the HBO drama series The Wire, portrayed by S. Robert Morgan. A blind man, he runs an East-Side Baltimore bar, and is Omar Little's bank and advisor. Like his character, actor S. Robert Morgan is blind; he lost his sight to macular degeneration in his twenties.

<span class="mw-page-title-main">Nipple stimulation</span> Human sexual practice

Nipple stimulation or breast stimulation is stimulation of the breast. Stimulation may be by breastfeeding, sexual activity, or an indirect non-sexual response. As part of sexual activity, the practice may be performed upon, or by, people of any gender or sexual orientation. It may occur with the use of fingers, orally, such as by sucking or licking, as well as by use of an object.
