Antonio Coppi, «vera gloria italiana»
No full textGianpaolo Fassino presenta in questo saggio la figura di Antonio Coppi. Originario di Andezeno, ma vissuto per la gran parte della sua vita a Roma, Antonio Coppi (1783-1870) è noto soprattutto per aver proseguito, fino al 1861, i settecenteschi Annali d’Italia di Lodovico Antonio Muratori. Per lungo tempo gli è stata impropriamente attribuita anche una piccola monografia di storia locale, le Memorie istoriche della Città di Chieri. Un’attenta rilettura di quest’opera ha consentito ora di espungere dalla bibliografia degli scritti di Coppi questo testo, frutto in realtà del lavoro di un altro erudito chierese, Giuseppe Broglia di Casalborgone

No full textAstrophysical disks in which the disk self-gravity is more important than the gravity force associated with the central object can have significant plasma components where appreciable toroidal current densities are produced. When the vertical confinement of the plasma rotating structures that can form is kept by the Lorentz force rather than by the vertical component of the gravity force, the disk self-gravity remains important only in the radial equilibrium condition, modifying the rotation curve from the commonly considered Keplerian rotation. The equilibrium equations that are solved involve the vertical and the horizontal components of the total momentum conservation equations, coupled with the lowest order form of the gravitational Poisson's equation. The resulting poloidal field configuration can be visualized as a sequence [1] of Field Reverse Configurations, in the radial direction, consisting of pairs of oppositely directed current channels. The plasma density thus acquires a significant radial modulation that may grow to the point where plasma rings can form [2]. [1] B. Coppi, Phys. Plasmas, 12, 057302 (2005) [2] B. Coppi and F.

Self-gravitating Disks and Plasma Structures Immersed in Them
No full textWhen considering axisymmetric differentially rotating plasma structures in the prevalent gravity of a central object these are found to be characterized by a sequence of current filaments and to develop a corresponding ring sequence configuration for the plasma. The same type of structure can be found when the self-gravity of a differentially rotating plasma component is no less important than the gravity of the central object. Then in addition to the vertical and horizontal equilibrium equations to be solved, Poisson's equation for the gravitational potential has to be dealt with. The fact that the vertical equilibrium is ensured by the vertical component of the Lorentz force due to the internal plasma currents (``Lorentz compression'') simplifies the problem considerably.

Subclinical Vascular Damage: Current Insights and Future Potential

As patients age, they change their exposure to various risk factors and accumulate comorbidities by changing their subjective cardiovascular risk, so it is necessary to undertake personalized early and preventive diagnostic actions. The main approach to asymptomatic vascular disease is based on primary prevention with the adoption of a healthy lifestyle. Indeed, lifestyle influences most of the traditional risk factors. In recent years, important differences between the sexes regarding cardiovascular risk factors have emerged and in particular, risk factors specific for female sex have been identified. Women are more likely to be categorized into lower risk categories for cardiovascular disease and, as a result, receive less lifestyle counseling than men, as well as less intensive prevention. This narrative review aims to analyze CVD risk prevention in asymptomatic atherosclerosis with a look at new emerging factors. In the end, we quickly analyzed the effects of the recent pandemic on lifestyle and cardiovascular risk and the potential negative effects in the long term.Keywords: prevention, risk factors, women, lifestyle, microbiota, pandemi
