How can you calculate BOD Mathmaticly?
The Biochemical Oxygen Demand (BOD) of a sample is the amount of dissolved oxygen required by aerobic microorganisms to breakdown organic matter in the sample.The test is simple:Measure the Dissolved Oxygen content of the sample (a)Place in a sealed darkened bottleIncubate for 5 days at 20'CMeasure the Dissolved Oxygen content of the incubated sample (b)Generally you're using this test to analyse contaminated water, so you'll want to dilute it first - it may be that aren't enough aerobic microorganisms present to give you a measurable result, in which case you'll need to inoculate the sample with a suitable culture.The BOD of the sample = a - bBOD is expressed in mg O2/L of sample.Extra CreditGenerally you're using this test to analyse contaminated water, so you'll want to dilute it first - it may be that aren't enough aerobic microorganisms present to give you a measurable result, in which case you'll need to inoculate the sample with a suitable culture.The BOD of a diluted innoculated sample = ((a - b) - BOD of inoculated culture) * dilution factor

What is the factors which may affect the BOD experiment?
As BOD5 depends on the growth of microbes the test can be adversely affected by * Temperature * Toxics * Turbidity * Light * Agitation * Species of Microbe * Microbial contamination by a wild population * Nature of the organics present * Skill of the analyst * Data entry errors * Lack of blanks and samples of known strength * Equipment accuracy and maintenance

What are the characteristics of a 2 x 2 experimental design?
A 2 x 2 experimental design involves manipulating 2 factors that you are interested in, with 2 levels of each variable. For example, you may want to see the effects of both level of caffeine (factor 1) and difficulty of test (factor 2) on test performance. Thus, for factor 1 - caffeine level, you may have high amount of caffeine (factor 1 level 1), and low amount of caffeine (factor 1 level 2). For factor 2 - difficulty of test, you may have a difficult test (factor 2 level 1), and an easy test (factor 2 level 2). Then you randomly assign individuals to one of the four conditions in your experiment. In this example case the conditions would be: 1. Low caffeine, difficult test 2. High caffeine, difficult test 3. Low caffeine, easy test 4. High caffeine, easy test Then, to analyze your data, you would conduct a factorial ANOVA using SPSS or by hand if you so desire.
If you missed one cycle and pregnancy test came out negative what can be the cause?
There could be several possibilities.The test could be wrong. Seriously, it happens, get another one (different brand that tests different criteria, preferably). Ultimately, see your doctor and have a proper lab pregnancy test done.Changes in your diet can affect menstruation.Your age and state of body development may have something to do with it.If you are using hormonal birth controls or certain medications, they may affect menstruation.Your weight (too light/too heavy) might be a factor.Stress may also be a factor.
