Bulb
In botany, a bulb is a short underground stem with fleshy leaves or leaf basesBell, A.D. 1997. ''Plant form: an illustrated guide to flowering plant morphology''. Oxford University Press, Oxford, U.K. that function as food storage organs during dormancy. In gardening, plants with other kinds of storage organ are also called ornamental bulbous plants or just ''bulbs''. Description The bulb's leaf bases, also known as scales, generally do not support leaves, but contain food reserves to enable the plant to survive adverse conditions. At the center of the bulb is a vegetative growing point or an unexpanded flowering shoot. The base is formed by a reduced stem, and plant growth occurs from this basal plate. Roots emerge from the underside of the base, and new stems and leaves from the upper side. Tunicate bulbs have dry, membranous outer scales that protect the continuous lamina of fleshy scales. Species in the genera ''Allium'', '' Hippeastrum'', '' Narcissus'', and ''Tulipa' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flash (photography)
A flash is a device used in photography that produces a brief burst of light (lasting around of a second) at a color temperature of about 5500 K to help illuminate a scene. The main purpose of a flash is to illuminate a dark scene. Other uses are capturing quickly moving objects or changing the quality of light. ''Flash'' refers either to the flash of light itself or to the electronic flash unit discharging the light. Most current flash units are electronic, having evolved from single-use flashbulbs and flammable powders. Modern cameras often activate flash units automatically. Flash units are commonly built directly into a camera. Some cameras allow separate flash units to be mounted via a standardized accessory mount bracket (a '' hot shoe''). In professional studio equipment, flashes may be large, standalone units, or studio strobes, powered by special battery packs or connected to mains power. They are either synchronized with the camera using a flash synchronization ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulbus Glandis
The bulbus glandis (also called a bulb or knot) is an erectile tissue structure on the penis of canid mammals. During mating, immediately before ejaculation the tissues swell up to lock ('' tie'') the male's penis inside the female. The locking is completed by circular muscles just inside the female's vagina; this is called "the knot" tightening thus preventing the male from withdrawing. The circular muscles also contract intermittently, which has the effect of stimulating ejaculation of sperm, followed by prostatic fluid, as well as maintaining the swelling of the penis and therefore the tie, for some time. For domestic dogs the tie may last up to half an hour or more, though usually less. When male canines are sexually excited, the bulbus glandis may swell up inside the penile sheath, even if the dog has been neutered. The bulbus glandis also occurs in the penises of some pinnipeds, including South American fur seals. See also * Canine reproduction Canine reproduction is t ...

Testicles
A testicle or testis ( testes) is the gonad in all male bilaterians, including humans, and is homologous to the ovary in females. Its primary functions are the production of sperm and the secretion of androgens, primarily testosterone. The release of testosterone is regulated by luteinizing hormone (LH) from the anterior pituitary gland. Sperm production is controlled by follicle-stimulating hormone (FSH) from the anterior pituitary gland and by testosterone produced within the gonads. Structure Appearance Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. For 85% of men, the right testis hangs lower than the left one. Measurement and volume The volume of the testicle can be estimated by palpating it and comparing it to ellipsoids (an o ...

BULB Act
United States Lighting Energy Policy is moving towards increased efficiency in order to lower greenhouse gas emissions and energy use. Lighting efficiency improvements in the United States can be seen through different standards and acts. The Energy Independence and Security Act of 2007 laid out changes in lighting legislation for the United States. This set up performance standards and the phase-out of incandescent light bulbs in order to require the use of more efficient fluorescent lighting. EISA 2007 is an effort to increase lighting efficiency by 25-30%. Opposition to EISA 2007 is demonstrated by the Better Use of Light Bulbs Act and the Light Bulb Freedom of Choice Act. The efforts to increase lighting efficiency are also demonstrated by the Energy Star program and the increase efficiency goals by 2011 and 2013. A ban on the manufacture and sale of most general purpose incandescent bulbs in the U.S. took effect on August 1, 2023. Incandescent light bulbs , incandescent lig ...

Bulb Energy
Bulb Energy Ltd, trading as Bulb, was an energy supply company in the United Kingdom acquired by Octopus Energy in 2022. Founded in 2013, the company attracted venture capital from DST Global and Magnetar Capital and ran at a financial loss while achieving rapid growth in customers. Bulb claimed to provide electricity and gas from renewable or off-set sources. As of November 2021, it had a share of approximately 5-6% of the UK energy market and was considered the seventh largest in the country. In September 2021, the company sought a bailout due to financial problems caused by increasing natural gas prices. Instead, it was placed into the Energy Supply Company Administration (a special administration regime) by industry regulator Ofgem on 24 November 2021 following a refusal by investors to provide further funding. While customers of other failed suppliers have been transferred by Ofgem to new suppliers, the regulator decided Bulb was too large, so it became the first energy c ...

Bulb (photography)
The Bulb setting (abbreviated B) on camera shutters is a momentary-action mode that holds shutters open for as long as a photographer depresses the shutter-release button. The Bulb setting is distinct from shutter's Time (T) setting, which is an alternate-action mode where the shutter opens when the shutter-release button is pressed and released once, and closes when the button is actuated again. History Decades before the first flashbulbs, some box cameras and many view cameras and folding cameras came with a detachable pneumatic shutter release with a rubber bulb on the end; "Bulb" refers to the rubber shutter release bulb. Though mechanically timed exposures could also be triggered by squeezing the shutter release bulb, "Bulb" exposures then had the same momentary action as camera shutters have today, as per this description from Sears Roebuck's 1909 ''Cameras Photographic Supplies'': Around 1894 in Germany, the momentary-action setting on camera shutters made by C. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber Bulb
Rubber bulbs are used in chemistry laboratories, by placing them on top of a glass or plastic tube. It serves as a vacuum source for filling reagents through a pipette or pasteur pipette and also help control the flow of liquid from the dropping bottle. By using rubber bulb, the contact of the mouth to the chemicals can be avoided. These rubber rods come in different shapes, sizes and colors. Large rubber bulbs The larger rubber bulbs are commonly used to draw liquid through a pipette when the reagents are needed in a larger amount. These rubber bulbs will complement larger pipettes and plastic rods, as the glass will easily break due to uneven pressure distribution. Small rubber bulbs The smaller rubber bulbs are well suited with small pipettes to draw smaller amount of reagents and can attach to both glass, as well as plastic rods. They are very commonly used for droppers as small sized rubber bulbs help control the amount of drops more precisely. Rubber bulb alternatives Th ...
