On 12 April 2018, the police said that Rakesh Kumar, who leaked the class 12 economics paper, had leaked class 10 mathematics paper also. [40] Consequently, the Central Board of Secondary Education has put in place a system of "encrypted" question papers, which are supposed to be printed by the schools half an hour before the exam starts. [41]
Volcano plot showing metabolomic data. The red arrows indicate points-of-interest that display both large magnitude fold-changes (x axis) and high statistical significance (-log 10 of p value, y axis). The dashed red line shows where p = 0.05 with points above the line having p < 0.05 and points below the line having p > 0.05.
Volcano plot for the decomposition of formic acid on transition metals. In chemistry, the Sabatier principle is a qualitative concept in heterogeneous catalysis named after the French chemist Paul Sabatier. It states that the interactions between the catalyst and the reactants should be "just right"; that is, neither too strong nor too weak. If ...
Augustine Volcano (Alaska) during its eruptive phase on January 24, 2006. A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface.
R. Bhutani, K. Pande, J.S. Ray, R.S. Smitha, N. Awasthi & A. Kumar, Paper No. 268–9, 2014 GSA Annual Meeting in Vancouver, British Columbia (19–22 October 2014) Siebert L, Simkin T (2002–present). Volcanoes of the World: an Illustrated Catalog of Holocene Volcanoes and their Eruptions.
In 1980, volcanologist George P. L. Walker proposed the Hatepe eruption as the representative of a new class called ultra-Plinian deposits, based on its exceptional dispersive power and eruptive column height. [8] A dispersal index of 50,000 square kilometres (19,000 sq mi) has been proposed as a cutoff for an ultra-Plinian eruption. [8]
A volcano erupted in southern Iceland, near the town of Grindavík and the Blue Lagoon spa, marking the region's seventh eruption in a year. Iceland volcano flares in region's 7th eruption in one year
Often, a volcano may have a deep magma chamber many kilometers down, which supplies a shallower chamber near the summit. The location of magma chambers can be mapped using seismology : seismic waves from earthquakes move more slowly through liquid rock than solid, allowing measurements to pinpoint the regions of slow movement which identify ...
