Analysis of Physicochemical Indexes and Volatile Components of Giant Salamander Meat during Cold Storage

open access: yesShipin gongye ke-ji, 2022
In order to explore the changes of physicochemical indexes and volatile components of giant salamander meat during cold storage (4 ℃, 0~8 d), the sensory evaluation, total volatile basic nitrogen (TVB-N) value and total bacterial count of giant ...

Oil price shocks against stock return of oil- and gas-related firms in the economic depression: A new evidence from a copula approach

open access: yesCogent Economics & Finance, 2020
This research examines the influence of world crude oil price shocks on the financial performance of Vietnamese oil- and gas-related firms. Based on copula approach and the sample data of domestic giant oil- and gas firms from 2009 to 2019, in particular

The Search for other Earths: limits on the giant planet orbits that allow habitable terrestrial planets to form [PDF]

open access: yesAstrophys.J. 643 (2006) L131-L134, 2006
Gas giant planets are far easier than terrestrial planets to detect around other stars, and are thought to form much more quickly than terrestrial planets. Thus, in systems with giant planets, the late stages of terrestrial planet formation are strongly affected by the giant planets' dynamical presence. Observations of giant planet orbits may therefore

Rapid Formation of Gas Giant Planets around M Dwarf Stars [PDF]

open access: yesAstrophys.J. 643 (2006) 501-508, 2006
Extrasolar planet surveys have begun to detect gas giant planets in orbit around M dwarf stars. While the frequency of gas giant planets around M dwarfs so far appears to be lower than that around G dwarfs, it is clearly not zero. Previous work has shown that the core accretion mechanism does not seem to be able to form gas giant planets around M ...

The growth of planets by pebble accretion in evolving protoplanetary discs [PDF]

open access: yesA&A 609, C2 (2018), 2015
The formation of planets depends on the underlying protoplanetary disc structure, which influences both the accretion and migration rates of embedded planets. The disc itself evolves on time-scales of several Myr during which both temperature and density profiles change as matter accretes onto the central star.

The significance of coal-derived gas in major gas producing countries

open access: yesPetroleum Exploration and Development, 2019
The core of coal-derived gas theory is that coal measure is the gas source, and the hydrocarbon generation of coal measure is dominated by gas and supplemented by oil, so discoveries in related basins are dominated by gas fields.

Exploration status of the deep Sinian strata in the Sichuan Basin: Formation conditions of old giant carbonate oil/gas fields

open access: yesNatural Gas Industry B, 2020
To construct a giant Sichuan gas province, it is in an urgent need of exploring new replacement areas with abundant natural gas resources and great exploration potential. In this paper, the formation conditions (e.g.

Planetary formation and early phases

open access: yesComptes Rendus. Physique, 2023
Planets form in proto-planetary disks. In this review, we describe the structure and properties of such disks, and the various phenomenons that lead to the final product: a planetary system. First, micrometre dust settles and coagulates.

New progresses in basic geological theories and future exploration domains of natural gas in China

open access: yesNatural Gas Industry B, 2018
As natural gas exploration expands to deep, ultra-deep and unconventional areas, more and more complex exploration targets are encountered. In this circumstance, it is necessary to improve the existing basic natural gas geological theories for guiding ...
