The next step was the ,neutralization, of excess ,acid,. For that purpose a calcium-hydroxide slurry containing 25 wt% Ca(OH)2 was added to the glycerol phase to reach a pH value of about 5. All precipitated calciumphosphates was eliminated by simple filtration on G3 glass filter. The filtrate coming from such a ,neutralization, step is yellow or light

By starting with 12.5% of the animals infected and varying the transmission rate, a transmission rate of 1.45 was found to be ,suitable, to obtain the observed increase. From the values reported in Table 5 and in Figure 7 , it is evident how fast the infection can spread within the farm and how after two weeks the disease reached an incidence close to 100%.

A few species also have hemagglutinin glycoproteins. Coronavirus's nucleic ,acid, is non-segment single-stranded (+) RNA with a length of 27-31kd. It is the longest RNA nucleic ,acid, strand in RNA viruses and has important structural characteristics unique to positive-strand RNA: that is, the 5 'end of the RNA strand is methylated.

Feb 25, 2018 - Hydrogen Sulfide, also known as H2S, is a colorless, flammable, extremely hazardous gas with a “rotten egg” smell. It occurs naturally in crude petroleum and natural gas, and can be produced by the breakdown of organic matter and human/ animal wastes (e.g., sewage). It is heavier than air and can collect in low-lying and enclosed, poorly ventilated areas such as basements ...

Concrete corrosion is one of the most significant problems affecting valuable sewer infrastructure on a global scale. This problem occurs in the aerobic zone of the sewer, where a layer of surface corrosion develops on the exposed concrete and the surface pH is typically lowered from around 11–10 (pristine concrete) to pH 2–4. Acidophilic microorganisms become established as biofilms ...
