In the present study, properties of silver nanoparticles (AgNPs) such as average size, size distribution andmorphology were investigated by Tollens, polysaccharide, modified polysaccharide and microbial methods.The synthesized AgNPs were characterized by UV-visible spectroscopy, scanning electron microscopy(SEM), transmission electron microscopy (TEM), dynamics light scatterin...

This paper deals with the joint verification of the inequalities of Modus Ponens and Modus Tollens in Fuzzy Logic. Although the case of Modus Ponens was partially considered before, the case of Modus Tollens and the joint satisfaction of both inequalities are studied by the first time. The cases of R-implications, Simplications, Q-implications and MamdaniLarsen implications are separatedly cons...

nanotechnology has been advanced since the last decades. among all nanomaterials that have been developed, nanosilver is the most frequently used nanoparticles. its release into natural water bodies is inevitable due to its broad applications. nanosilver (nag) was prepared via tollens method using. the morphology, size distribution and average size of the obtained nag was characterized using tr...

This paper deals with numerical functions able to functionally express operators defined as , and verifying either Modus Ponens or Modus Tollens, or both. The concrete goal of the paper is to search for continuous t-norms and strong-negation functions for which it is either (Modus Ponens), or (Modus Tollens), or both, for all in and a given . Functions are taken among those in the most usual fa...

Nodus Tollens’ is the title of a dance art work that uses psychological approach Bipolar Disorder. The choreography composed to express idea affects one's mindset and emotions. Tollens' picture behavior, habits, character humans with bipolar who are transferred into gestures using contemporary techniques. This study describes process choreographing creation exploration body three episodes depre...

Two advances in the development of a one-pot method to prepare silver nanoparticles (AgNPs) using the Tollens' reagent are described. First, a template-directed process of AgNP synthesis using resorcinol triazole ligands bearing two pendent galactose sugars is shown. Second, the conversion of these AgNPs into SERS nanotags is demonstrated using malachite green isothiocyanate as the Raman report...
