For reasons of robustness, it is recommendable to use diverse and partly redundant sensors for this purpose.
Since Petri nets (PNs) are both simple and strong tools for the description and the design of such concurrent processes, it is recommendable to deploy them for SDR.
In a development strategy, it is recommendable to stimulate a key sector because it will impact positively on growth (Chenery and Watanabe 1958; Hirschman 1958).
It is recommendable to try several different prices with the only condition of not being so high that all the utilities are negative.
These findings point out that, from an applied point of view, it is recommendable using catalytic layers as thinner as possible as well as high formic acid concentrations.
Instead of applying a classical plaster mortar and a reinforcing net, it is recommendable to use a composite mortar including PP fibers, in a proper dosage, that can lead to a more suitable outcome.
Hence, it is recommendable that more research should be done regarding immersion in artificial saliva at basic pH because of its clinical relevance that the pH of resting saliva ranges from pH 5.6 to 7.6 [9, 10].
These tests emulate typical situations occurring while an operator is handling sensors and serve to determine in which of these situations it is recommendable for lab personnel to use static control measures like wrist straps to ground lab personnel.
Simulations allow us demonstrating that to increase the productivity of raceway reactors it is recommendable to reduce the water depth into the cultures and to increase the mass transfer capacity of the entire reactor.
Hence it is recommendable to use tips with radius lower than average feature size, check their shape by deconvolution, and test several tips prior to interpretation of the data.
