he take swan neck shape flasks
Pasteur solved the problem of limiting exposure to air by designing a swan-necked flask that allowed air to enter but prevented dust and microbes from passing through. This design enabled him to demonstrate that spontaneous generation did not occur, as microorganisms did not appear in the broth unless the flask was tilted to allow contamination.

Spallanzani discovered that the theory of spontaneous generation was incorrect; boiling water is a better sterilizer than hot air; and some microorganisms can live for days in a vacuum before dying...
The limiting reactant, by definition, will be completely converted to the desired product. If one reactant is substantially more expensive than the other reactant(s), it is monetarily sensible to make the most expensive reactant the limiting one, so that the total material cost per unit of product will be minimized.
well the problem was that he could not meet one direction he had tried and tried until he gave up ............... and died

A limiting problem sets restrictions on what is possible or achievable, while a defining problem helps to clearly identify the key issue or aspect that needs to be addressed. Limiting problems can hinder progress, while defining problems provide a focus for problem-solving efforts.

The problem with LED lights is that they can emit blue light, which can disrupt sleep patterns and cause eye strain. This issue can be addressed by using LED lights with warmer color temperatures, using dimmers or filters to reduce blue light, and limiting exposure to LED lights before bedtime.
In a limiting reactant problem, you must identify which reactant will be completely consumed first to determine the maximum amount of product that can be formed. Other stoichiometry problems may involve finding the amount of product produced by known quantities of reactants without considering limiting factors.
Nietzsche believed that Socrates' problem was his emphasis on reason and logic, which he saw as limiting human potential and creativity.
The limiting factor is the biggest thing that stands in the way of you solving a problem or accomplishing an objective. Locate the limiting factor as part of your decision-making process to avoid making mistakes. Failure to follow the principle of the limiting factor leads to many poor decisions.
Louis Pasteur suggested the idea of Pasteurization. Pasteurization is the process in which food is heated to a certain temperature, so that the food-spoiling bacteria in the food is killed, thus preserving the food.
desensitisation due to mass media exposure
They can be but the average person will probably never get enough exposure to ever be a problem.
Aplastic anemia, almost certainly contracted from exposure to radiation.
