A man whose semen is used for inseminating someone other than his wife or partner. An anonymous donor is someone not known to the recipient. A recipient selected donor is a man selected by the recipient, other than her partner, to donate semen for artificial insemination.
an eligible dog or cat who regularly provides a donation of blood to the Animal Blood Bank where we process the blood into one or more blood products. See Donor types, donor benefits, donor eligibility and blood products.
The individual from whom the organ or tissue is removed, either living or cadaveric; the three categories of `donor' referred to within the context of this report, are: INTENDED DONOR - An individual who has expressed a desire, or intention, to become an organ or tissue donor upon death, or, when appropriate during life. POTENTIAL DONOR - An individual identified within a healthcare facility as being appropriate to pursue as an organ or tissue donor. ACTUAL DONOR - An individual from whom at least one organ or tissue has been procured, allocated and transplanted. DONOR REGISTRY - A database of individuals who have given consent to become organ donors in the eventuality that they might become a candidate.
Some tissues for transplantation may be donated by living donors, such as kidneys or bone marrow. Islets can only be retrieved for transplants from people who have been classified as clinically brain dead. They cannot be transplanted from living donors (see Donated tissue).
A person or couple who chooses to provide their eggs, sperm or embryos for use by others. All UK donors must be screened for known infectious diseases, and have no legal right or obligation to any child born as a result of treatment given in a UK licensed clinic to top of page
An individual or company making a contribution to a charitable organization. In the case of the myCFO Charitable Fund Program and the Harris Charitable Giving Fund Program, the donor opens his or her account by making a contribution to the Foundation. An account can have one donor or two, if the contributed assets are jointly held.
A donor is anyone who gives resources - financial, social, intellectual and time - to a nonprofit organization, public charity or fund. A donor is committed to making a difference in society. (See Grantor)
embryo: An embryo formed from the egg of a woman who has donated it for transfer to a woman who is unable to conceive with her own eggs (the recipient). The donor relinquishes all parental rights to any resulting offspring.
An individual or organization making a contribution to a charity. In the case of Franklin Templeton Charitable Giving Fund, donors open an account by making an irrevocable contribution to the Renaissance Charitable Foundation, Inc.. An account can have one donor or two, if the contributed assets are jointly held.
The person donating property for the benefit of another, usually through the legal mechanism of a trust. Some countries refer to the trust donor as a "settlor." Also used to describe the person who signs a power of attorney.
group five elements in the periodic table such as phosphorus, arsenic and antimony have one more electron in the outer most energy level than silicon. When these atoms are introduced into silicon, an impurity level is created very near the conduction band. At zero degrees Kelvin the impurity level is filled, at room temperature sufficient energy is available to excite electrons from the impurity level into the conduction band. Because these elements introduce impurity levels that donate electrons they are referred to as donors.
A material that is intentionally added to a pure semiconductor material in order to increase the population of free electrons in that semiconductor, resulting in a net negative charge. A semiconductor that has had donor material added to it is called "n-type."
In a solar photovoltaic device, an n-type dopant, such as phosphorus, that puts an additional electron into an energy level very near the conduction band; this electron is easily exited into the conduction band where it increases the electrical conductivity over than of an undoped semiconductor.
