BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.
Measurements were called oxygen consumed from permanganate rather than organic substances' oxygen demand. Potassium permanganate's effectiveness at oxidizing organic compounds varied widely, and in many cases, biochemical oxygen demand (BOD) measurements were often much greater than results from COD measurements. This indicated that potassium ...
The text-book, Market Research and Analysis by Lyndon O. Brown (1937) became one of the popular textbooks during this period. [36] As the number of trained research professionals proliferated throughout the second half of the 20th-century, the techniques and methods used in marketing research became increasingly sophisticated.
Reid and Bojanic(2010) claimed that, " The term market research informs relatively narrowly than Marketing Information System(MkIS) which is altered from the term management information systemization. Market research indicates that information is collected for a specific reason or project; the major objective is a one-time use. "[2]
The difference in DO and the dilution factor are used to calculated BOD 5. The resulting number (usually reported in parts per million or milligrams per liter) is useful in determining the relative organic strength of sewage or other polluted waters. The BOD 5 test is an example of analysis that determines classes of materials in a sample.
The marketing research process is a six-step process involving the definition of the problem being studied upon, determining what approach to take, formulation of research design, field work entailed, data preparation and analysis, and the generation of reports, how to present these reports, and overall, how the task can be accomplished. [1]
The literature defines several areas in which market analysis is important. These include: sales forecasting, market research, and marketing strategy. Not all managers will need to conduct a market analysis. Nevertheless, it would be important for managers that use market analysis data to know how analysts derive their conclusions and what ...
BOD Bottle BOD test bottles at the laboratory of a wastewater treatment plant. BOD Bottle or an incubation bottle is a main apparatus used for the Biological Oxygen Demand (BOD) test. During the five-day BOD or BOD5 test process, the BOD bottle is used for incubating diluted samples under the 20 °C or 68 °F of temperature.
