Psychotria viridis (Rubioideae: Rubiaceae), popularly known as chacrona, is commonly found as a shrub in the Amazon region and is well-known to produce psychoactive compounds, such as the N,N-dimethyltryptamine (copyright).Together with the liana Banisteropsis caapi, P.viridis is one of the main components of the emtek 2113 Amerindian traditional,
Benign nerve sheath tumors include here schwannomas, neurofibromas and perineuriomas.The malignant counterpart of a nerve sheath tumor is designated as a malignant peripheral nerve sheath tumor (MPNST).Lately, benign nerve sheath tumors comprising more than one component have been described, including hybrid schwannomas/perineuriomas.However, malig
Lithium sulfide-based materials have been considered as potential positive electrodes for the next generation batteries.Lithium sulfide is the fully lithiated form of sulfur, i.e., they share the same high theoretical capacity.However, it has the benefit of already containing lithium, which allows making cells with lithium-free negative electrodes.
In this paper, we define and study extensively a new type of external sets in , we call it "convex galaxies".We show that these convex external sets may be classified in some definite types.More precisely, we obtain the following : (1)Let be a convex galaxy which is symmetric with respect to zero, then (i) is an - galaxy (0) if and only if there ex
This paper presents a case study on the behaviour of precast reinforced columns with non-conventional cross-section.An experimental program was developed to lorenametaute.com verify the serviceability and ultimate limit states of these columns, loaded with eccentric compression forces.In addition, results obtained through a theoretical model based
