EAST LANSING, Mich. — Monitoring oxygen levels in water has applications for oil spills, fish farming, brewing beer and more – and a professor at Michigan State University is poised to help supply that need.
The concept of oxygen sensors isn’t new. The challenge, however, has been manufacturing one that can withstand fluctuations in temperature, salinity, carbon dioxide, phosphates and biological wastes. Ruby Ghosh, associate professor of physics, was able to overcome those obstacles as well as build one that provides real-time data and is relatively inexpensive.
“We have been able to take advantage of steep price drops in components used for telecommunications and medical imaging,” said Ghosh, who will be presenting her research at the
Bio-Optics: Design and Application meeting April 4-6 at Monterey, Calif. “We were able to build a sensor with relatively inexpensive components, yet it is sensitive, reliable and can operate in a variety of environments.”
Constantly testing dissolved oxygen is critical in industries such as:

Aquaculture – where fish are raised in oxygen-rich, high-density environments.
Beverage manufacturing – which constantly monitors dissolved oxygen levels during the fermentation and bottling processes.

    Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of ppm (parts per million). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below.…

    Beer influenced the transition from hunting and gathering to agricultural based societies because it gave people a keen interest in grain storage. Beer was discovered as gruel, a mixture of water and grain, that was heated. It stimulated a dopaminergic release, causing the people that experienced the flavor to yearn for that rewarding sensation more. Standage noted that people could store a pound of grain a year, which caused the transition away from the savage – minded lifestyle even more appealing (13). Beer is a drink used to relax and celebrate, and seeing that the world functions through the ability to communicate, beer was extremely valuable to the people of the time period. In addition, it is possible that a trade-off of some sort was made possible, as some would convert to beer-making and exchange their craft for meat and berries. In the book, it was said that beer “was truly the defining drink of those first great civilizations,” and these various new abilities brought into play through beer makes this understandable (30). All of these positive and attractive new possibilities are ways that beer influenced the switch from the traditional hunt – and – gather mentality to a more society – oriented lifestyle with agriculture.…

    Once the sample was collected, pH, temperature, dissolved oxygen, and turbidity were measured. To determine turbidity, a transparency tube with a checkerboard pattern was used. The trasparency tube was emptied and then filled with water so that the pattern on the bottom could bnot be seen. Water was then slowly released and a measurement was taken when the checkerboard was visible again. There were some measurements that were not taken due to the lack of a thermometer on September 13th at Wellwoods Bayou and Wellwoods Lake. A sample bottle from each site was collected and analyzed by Meredith McManus in the lab to determine biological oxygen demand (BOD). Salinity was also measured at each site, but there was no salt present because all sites consisted of fresh…

    Fish and macroinvertebrates use dissolved oxygen to breathe through their gills and bacteria relies on dissolved oxygen to decompose dead organisms. Dissolved oxygen is oxygen that has water molecules mixed in as a result of the spread of air and the process of green plant photosynthesis producing waste. The dissolved oxygen range for water quality is 1-14 parts per million (ppm). This means that for out of a million…

    The pulse oximeter was invented in 1972, by Aoyagi and has the ability to display the oxygen saturation of the blood as a percentage. It is a simple procedure which requires placing a peg-like device on the end of a finger. The device emits a beam of light through the skin and measures the amount of light absorbed as the sensor passes through it. The more oxygen in the blood the brighter red the colour is which results in more light passing through, whereas a darker red which would indicate a lower amount of oxygen results in less light passing…
