Neutronization During Type Ia Supernova Simmering [PDF]
, 2007 Prior to the incineration of a white dwarf (WD) that makes a Type Ia supernova (SN Ia), the star "simmers" for ~1000 years in a convecting, carbon burning region. We have found that weak interactions during this time increase the neutron excess by an amount that depends on the total quantity of carbon burned prior to the explosion. This contribution is

Design and Production of an Autonomous Rotary Composter Powered by Photovoltaic Energy [PDF]
arXiv, 2021 The problem of household waste management is becoming more and more acute with the growth of economic development that the country of Morocco has experienced. Moreover, the management of this waste is a burden for the municipalities, in view of its cost, which is increasing with time.

Constraining the Type Ia Supernova Progenitor: The Search for Hydrogen in Nebular Spectra [PDF]
2007, ApJ, 670, 1275, 2007 Despite intense scrutiny, the progenitor system(s) that gives rise to Type Ia supernovae remains unknown. The favored theory invokes a carbon-oxygen white dwarf accreting hydrogen-rich material from a close companion until a thermonuclear runaway ensues that incinerates the white dwarf. However, simulations resulting from this single-degenerate, binary

A plastics hierarchy of fates: sustainable choices for a circular future [PDF]
arXiv, 2023 Plastics are ubiquitous in modern society, but the linear model of produce, use, and dispose results in massive amounts of resource consumption and pollution. Landfill and incineration of plastic waste is endemic, with no consensus on a clear path towards a more sustainable model.

Modeling subgrid combustion processes in simulations of thermonuclear supernovae [PDF]
2019 J. Phys.: Conf. Ser. 1225, 012004, 2019 Supernovae of type Ia are thought to arise from the thermonuclear incineration of a carbon-oxygen white dwarf stellar remnant. However, the detailed explosion scenario and stellar evolutionary origin scenario -- or scenarios -- which lead to observed supernovae are still quite uncertain.

Implementation - More than Monitoring and Enforcement: Evidence from the Implementation of the 1989 Municipal Waste Incineration Directive (89/429/EEC) in Four Member States [PDF]
, 2000 Researchers and policy-makers accept that implementation decisively influences the effectiveness of European (EU) environmental policy. Some Member States lead the development of EU policy and implement Directives with little problem.
