Lara, something can be okay without being optimal. I think what you choose to do should depend on your goals. If you want to create the most therapeutic, LAB-rich ferment, you would do better in an airtight system that would produce less acetic acid (vinegar produced when yeasts interact with oxygen) and more lactic acid. If you’re just going for flavor, enjoyment, and a decent amount of probiotics, then an open air ferment may be all you need. The only problem I see with open air ferments is that they are more likely to mold or produce inconsistent batches. Thoughtful, well-researched, and well-meaning people can all reasonably argue about how mold may or may not be “safe,” but we can all agree it’s less than ideal.
Sodium silicate or Modified starch are hitherto used as adhesive for making Paper core. Both these adhesives are highly alkaline with very high pH which damage the paper and rollers of winders and also create hazardous working conditions for workman. It is also classified as highly pollutant and Disposal of the same is problem.
The biggest problem is that core prepared using these adhesives does not give high crushing strength or compressive strength to the core which is very much essential for the modern Paper machine. Paper reels gets damage while inserting chuck with high pressure to the end of the core resulting in rejection of Paper reel.
Church knew that standard cloning methods wouldn’t work, since bird embryos develop inside shells and no museum specimen of the passenger pigeon (including Martha herself, now in the Smithsonian) would likely contain a fully intact, functional genome. But he could envision a different way of re-creating the bird. Preserved specimens contain fragments of DNA. By piecing together the fragments, scientists can now read the roughly one billion letters in the passenger pigeon genome. Church can’t yet synthesize an entire animal genome from scratch, but he has invented technology that allows him to make sizable chunks of DNA of any sequence he wants. He could theoretically manufacture genes for passenger pigeon traits—a gene for its long tail, for example—and splice them into the genome of a stem cell from a common rock pigeon.
