Aims. We study the LMC interstellar medium in the field of the nebula N157B, which contains a supernova remnant, an OB association, ionized gas, and high-density dusty filaments in close proximity. We investigate the relative importance of shock excitation by the SNR and photo-ionization by the OB stars, as well as possible interactions between the supernova remnant and its environment. Methods...

X-ray emission from the supermassive star Eta Carinae (η Carinae) originates from hot shocked gas produced by current stellar mass loss as well as ejecta from prior eruptive events. Absorption of this emission by cool material allows the determination of the spatial and temporal distribution of this material. Emission from the shocked gas can provide important information about abundances throu...

Pollution emitted by US manufacturers has been declining steadily over the past several decades, while at the same time, the real value of manufacturing output has been increasing. This cleanup has two sources: advances in production or abatement processes (“technology”), and changes in the composition of goods manufactured in the United States. The composition changes can be divided further in...

Fulfilment of environmental and social obligations is required for sustainable development. Green accounting integrates all consequences into corporate accounts. Disclosure Corporate responsibility a component performance tied to the social, economic, aspects company's programme that can be vital in cultivating stakeholders. The current research aims investigate effect disclosure on integrating...

We report the results of an XMM-Newton observation of Sgr A East and its surroundings. The X-ray spectrum of Sgr A East is well represented with a two-temperature plasma model with temperatures of ∼1 and ∼4 keV. Only the iron abundance shows clear spatial variation; it concentrates in the core of Sgr A East. The derived plasma parameters suggest that Sgr A East originated in a single supernova....
