Today, an Arnold-Chiari malformation is defined as a developmental pathology of the craniovertebral junction manifested by a discrepancy between the volume and contents of the posterior cranial fossa, which in turn leads to compression of neurological structures and changes in the cerebrospinal fluid circulation.There are several theories of the co
The integrated calcareous plankton biostratigraphy (planktonic foraminifera and calcareous nannofossils) and an accurate fieldwork, allowed us the reconstruction of the sedimentary evolution of the Longano Formation (Orbulina Marls).In particular the correlation between the bioevents recognised in the Orbulina Marls sequence and those recorded in a
The plasma electrolytic oxidation (PEO) surface modification process is able to improve the surface characteristics of titanium and titanium alloys by forming TiO2 coatings.Implementing the PEO process enhances corrosion and wear protection, tunes optical properties, and more importantly, modifies the biological activities of titanium and also its
In many cases involving hypothesis testing for Baby Hoodies parameters in multivariate Gaussian populations and certain other populations, likelihood ratio criteria, or their one-to-one functions, can be expressed in terms of the determinant of a real type-1 beta matrix.In geometrical probability problems, when the random points are type-1 beta dis
