Phase-change Incubator
The phase-change incubator is a low-cost, low-maintenance incubator that tests for microorganisms in water supplies. It uses small balls containing a chemical compound that, when heated and then kept insulated, will stay at 37 °C (approx. 99 °F) for 24 hours. This allows cultures to be tested without the need for a laboratory or an expensive portable incubator. Thus it is particularly useful for poor or remote communities. The phase-change incubator was developed in the late 1990s by Amy Smith, when she was a graduate student at MIT. Smith has also started a non-profit organization called ''A Drop in the Bucket'' to distribute the incubators and to train people on how to use them to test water quality. Her “Test Water Cheap” system could be used at remote locations to test for bacteria such as E.coli. Embrace, an organization that from Stanford University, is applying a similar concept to design low-cost incubators for premature and low birth weight babies in develo ...

Incubator (microbiology)
An incubator is a device used to grow and maintain microbiological cultures or cell cultures. The incubator maintains optimal temperature, humidity and other conditions such as the CO2 and oxygen content of the atmosphere inside. Incubators are essential for much experimental work in cell biology, microbiology and molecular biology and are used to culture both bacterial and eukaryotic cells. An incubator is made up of a chamber with a regulated temperature. Some incubators also regulate humidity, gas composition, or ventilation within that chamber. The simplest incubators are insulated boxes with an adjustable heater, typically going up to 60 to 65 °C (140 to 150 °F), though some can go slightly higher (generally to no more than 100 °C). The most commonly used temperature both for bacteria such as the frequently used E. coli as well as for mammalian cells is approximately 37 °C (99 °F), as these organisms grow well under such conditions. For other organisms used in bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microorganism
A microorganism, or microbe,, ''mikros'', "small") and ''organism'' from the el, ὀργανισμός, ''organismós'', "organism"). It is usually written as a single word but is sometimes hyphenated (''micro-organism''), especially in older texts. The informal synonym ''microbe'' () comes from μικρός, mikrós, "small" and βίος, bíos, "life". is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van Leeuwenhoek. In the 1850s, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In the 1880s, Robert Koch discovered that microorganisms caused the diseases tuberculosis, cholera, diphtheria, and anthrax. Because ...

Embrace (incubator)
Embrace Innovations is an Indian healthcare technology company specializing in infant warmers. The company produces neonatal warming bags which are used to help reduce the risk of hypothermia in pre-term infants. History Embrace was founded in 2008 by Jane Chen, Linus Liang, Naganand Murty and Rahul Panicker. The four founders met as graduate students at Stanford University in a Design for Extreme Affordability course, where they were challenged to design an infant incubator that would cost 1% the price of traditional incubators (about $20,000 in the US). On a 2007 fact-finding trip to Nepal and India, the team realised their design would have to take into account the infrastructural challenges in developing countries, including unreliable power and limited skills of healthcare staff. An initial prototype was developed resembling a baby sleeping bag with a removable, heatable wax insert that prevented hypothermia in premature and low-birth-weight babies, which took into acco ...

Low Birth Weight
Low birth weight (LBW) is defined by the World Health Organization as a birth weight of an infant of or less, regardless of gestational age. Infants born with LBW have added health risks which require close management, often in a neonatal intensive care unit (NICU). They are also at increased risk for long-term health conditions which require follow-up over time. Classification Birth weight may be classified as: * High birth weight (macrosomia): greater than * Normal weight (term delivery): * Low birth weight: less than ** Very low birth weight: less than ** Extremely low birth weight: less than Causes LBW is either caused by preterm birth (that is, a low gestational age at birth, commonly defined as younger than 37 weeks of gestation) or the infant being small for gestational age (that is, a slow prenatal growth rate), or a combination of both. In general, risk factors in the mother that may contribute to low birth weight include young ages, multiple pregnancies, previou ...

Appropriate Technology
Appropriate technology is a movement (and its manifestations) encompassing technological choice and application that is small-scale, affordable by locals, decentralized, labor-intensive, energy-efficient, environmentally sustainable, and locally autonomous. It was originally articulated as intermediate technology by the economist Ernst Friedrich "Fritz" Schumacher in his work ''Small Is Beautiful.'' Both Schumacher and many modern-day proponents of appropriate technology also emphasize the technology as people-centered. Appropriate technology has been used to address issues in a wide range of fields. Well-known examples of appropriate technology applications include: bike- and hand-powered water pumps (and other self-powered equipment), the universal nut sheller, self-contained solar lamps and streetlights, and passive solar building designs. Today appropriate technology is often developed using open source principles, which have led to ''open-source appropriate technolog ...
