The quantum mechanical model specifies the probability of finding an electron in the three-dimensional space around the nucleus and is based on solutions of the Schrödinger equation.
21 Αυγ 2024 · Typically seen as prominent retrocerebellar cerebrospinal fluid (CSF) appearing space with a normal vermis, normal 4 th ventricle, and normal cerebellar hemispheres. An enlarged cisterna magna usually measures >10 mm on midsagittal images.
14 Σεπ 2022 · The differential diagnosis of an enlarged retrocerebellar space (ERCS) includes mega cisterna magna (MCM), arachnoid cyst (AC), and cerebellar hypoplasia (CH). This study aimed to evaluate additional prenatal findings and postnatal outcome in fetuses with an enlarged retrocerebellar space.
The Rutherford model was devised by Ernest Rutherford to describe an atom. Rutherford directed the Geiger–Marsden experiment in 1909, which suggested, upon Rutherford's 1911 analysis, that J. J. Thomson 's plum pudding model of the atom was incorrect.
10 Ιαν 2017 · A 34 week gestational age fetus was shown to have a prominent retrocerebellar space (*) on axial ultrasound (left, face is at the right side of the image); the cisterna magna measured 11.2 mm (10 mm is upper normal at ultrasound).
23 Οκτ 2024 · The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some distance, much like planets revolving around the Sun.
5 Νοε 2020 · The Bohr Model of the Atom. The great Danish physicist Niels Bohr (1885–1962, ) made immediate use of Rutherford’s planetary model of the atom. Bohr became convinced of its validity and spent part of 1912 at Rutherford’s laboratory.
