Resumen
Saturno Saturno es Saturno.
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- La astronomía es la astronomía.
- Dinámica del anillo Dinámica del anillo
Sus antecedentes:
- El anillo C de Saturno exhibe una sutil corrugada.
- Anteriormente se había observado una estructura similar en el anillo D.
Objetivo del estudio:
- Para investigar el origen y las características de la corrugada de anillo C.
- Para determinar la naturaleza del evento que causó la inclinación del anillo.
Principales métodos:
- Análisis de la iluminación de los anillos de Saturno en agosto de 2009.
- Examen de las tendencias radiales en la longitud de onda de corrugado.
Principales resultados:
- Se detectó una corrugada con una amplitud de 2-20 metros y una longitud de onda de 30-80 km a través del anillo C.
- Las características de la estructura sugieren la formación de una regresión nodal diferencial de un anillo inclinado.
Conclusiones:
- La inclinación del anillo, que lleva a la corrugado, probablemente fue el resultado de un impacto por desechos interplanetarios dispersos.
- La masa de la nube de escombros se estima entre 10^11 y 10^13 kilogramos.

02:15The Contractile Ring
Contractile rings are composed of microfilaments and are responsible for separating the daughter cells during cytokinesis. Contractile ring assembly proceeds along with other cell cycle events; however, very few mechanistic details are known about the timing and coordination of the contractile rings with the cell cycle.
A small GTPase, RhoA, controls the function and assembly of the contractile ring. RhoA belongs to the Ras superfamily of proteins. The activation of formins by RhoA promotes...

01:10Deformation in a Circular Shaft
One of the distinctive characteristics of circular shafts is their ability to maintain their cross-sectional integrity under torsion. In other words, each cross-section continues to exist as a flat, unaltered entity, simply rotating like a solid, rigid slab. To understand the distribution of shearing stress within such a shaft, consider a cylindrical section inside this circular shaft. This section has a length of L and a radius of R, with one end fixed. The radius of the cylindrical section is...
02:02Chair Conformation of Cyclohexane
The chair conformation is the most stable form of cyclohexane due to the absence of angle and torsional strain. The absence of angle strain is a result of cyclohexane’s bond angle being very close to the ideal tetrahedral bond angle of 109.5° in its chair conformer. Similarly, the torsional strain is also absent owing to the perfectly staggered arrangement of bonds.

01:27Toroids
A toroid is a closely wound donut-shaped coil constructed using a single conducting wire. In general, it is assumed that a toriod consists of multiple circular loops perpendicular to its axis.
When connected to a supply, the magnetic field generated in the toroid has field lines circular and concentric to its axis. Conventionally, the direction of this magnetic field is expressed using the right-hand rule. If the fingers of the right hand curl in the current direction, the thumb points in the...

01:16Circular Orbits and Critical Velocity for Satellites
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.
