TL;DR: It is indicated that factors such as temperature, pH and bacterial biomass on mixed cultures, has a significant effect on fungal inhibition and OTA production and Pediococcus pentosaceus strains may be exploited as a potential OTA detoxifying agent to protect humans and animals health against this toxic metabolite.

TL;DR: It is shown that protonated ammonia clusters are all Eigen structures and the first solvation shell of the related ammonium ion core is saturated by four ammonia molecules, and a route for the accurate determination of the solvation energies of a proton in ammonia at a given temperature could be conceivable.
Abstract: The accurate determination of the solvation energies of a proton in ammonia is based on the precise knowledge of the structures of neutral and protonated ammonia clusters. In this work, we have investigated all the possible and stable structures of protonated ammonia clusters H+(NH3)n=2–9, along with their isomeric distribution at a specific temperature. New significant isomers are reported here for the first time and show that the structures of protonated ammonia clusters are not only branched linear as assumed by all previous authors. Branched linear structures are the only ones responsible for the population of protonated ammonia clusters for n = 4–6 at any temperature. However, for larger cluster sizes, these types of structures compete with branched cyclic, double cyclic, branched double cyclic and triple cyclic structures depending on the temperature. In addition, we have shown that protonated ammonia clusters are all Eigen structures and the first solvation shell of the related ammonium ion core is saturated by four ammonia molecules. We have also carried out a study of the hydrogen bond network of protonated ammonia clusters establishing the stability rule governing the various isomers of each cluster from estimated energies of the hydrogen bond types in H+(NH3)n=2–9. With all these results, a route for the accurate determination of the solvation energies of a proton in ammonia at a given temperature could be conceivable.

TL;DR: It is shown that by using the proposed adaptive controller, the semi-global asymptotic tracking and the boundedness of all variables in the closed-loop system are guaranteed without transgression of the constraints.

Journal ArticleDOI
TL;DR: The results revealed that Local pt variety has the highest level of oil, followed by trilinolein (LLL), linoleic acid (65.77%) and LLL (33.48%), therefore showing a great variability in the oil composition among cultivars.
