Energetic and Environmental Aspects of Individual Heat Generation for Sustainable Development at a Local Scale—A Case Study from Poland

Energies, 2020
The housing sector, especially with respect to energy generation to provide heating and domestic hot water, has been identified, after transport, as contributing the most to air pollution and the occurrence of low emissions in Poland. In particular, this

A new coral family and three new genera from the Lower Cretaceous of Puebla and Sonora (Scleractinia; Mexico)

Revista Mexicana de Ciencias Geológicas, 2022
Solitary corals currently assigned to the genus Plesiosmilia are common elements in Late Jurassic to Early Cretaceous coral faunas. The genus itself is poorly defined and its systematic position is questionable.

Trace element geochemistry of kerogens from the central Niger Delta

Journal of Petroleum Exploration and Production Technology, 2018
Trace elements in kerogens isolated from shale samples obtained from oil wells in the central Niger Delta were determined using atomic absorption spectrometry, with the aim to determine the depositional environment and source of the organic matter.

The first fossil cyphophthalmid harvestman from Baltic amber [PDF]

, 2011
The first fossil cyphophthalmid harvestman (Opiliones: Cyphophthalmi) from Palaeogene (Eocene) Baltic amber is described. This is only the third fossil example of this basal harvestman lineage; the others being from the probably slightly younger ...

The Fossil Phase in the Life of a Galaxy Group [PDF]

, 2007
We investigate the origin and evolution of fossil groups in a concordance LCDM cosmological simulation. We consider haloes with masses between $(1-5)\times10^{13} \hMsun$ and study the physical mechanisms that lead to the formation of the large gap in ...

Implications of "peak oil" for atmospheric CO2 and climate

, 2007
Unconstrained CO2 emission from fossil fuel burning has been the dominant cause of observed anthropogenic global warming. The amounts of "proven" and potential fossil fuel reserves are uncertain and debated.

Reconstruction of deglacial sea surface temperatures in the tropical Pacific from selective analysis of a fossil coral [PDF]

, 2005
The Sr/Ca of coral skeletons demonstrates potential as an indicator of sea surface temperatures (SSTs). However, the glacial-interglacial SST ranges predicted from Sr/Ca of fossil corals are usually higher than from other marine proxies.

Enigmacursor mollyborthwickae, a neornithischian dinosaur from the Upper Jurassic Morrison Formation of the western USA

Royal Society Open Science
Although their remains have been known since the 1870s, the small, bipedal ornithischian dinosaurs from the Upper Jurassic Morrison Formation of the western USA remain poorly known. The historic type specimens are incomplete and poorly preserved and have
