Journal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.Abstract Streptococcus iniae is a fish pathogenic bacterium distributed worldwide. It has a wide range of hosts, strong infectivity, causes high mortality, and severely hinders the healthy development of the aquaculture industry. A fish epidemic broke out in a Selenotoca multifasciata aquaculture farm, Hainan Province, China, and resulted in numerous ...

Heavy oil recovery efficiency using SAGD, SAGD with propane co-injection and STRIP-SAGD
, 2016 Primary oil recovery methods in heavy oil basins generally extract 5-10% of the available resource, with the vast majority left in the ground and recoverable only through Enhanced Oil Recovery (EOR) methods.

Crop Science, Volume 65, Issue 1, January/February 2025.Abstract Long‐term comparisons over several years between organic and synthetic management are lacking in sports turf research. Our objective was to investigate playing surface qualities and soil properties over an 8‐year period. For this trial, Kentucky bluegrass (KBG, Poa pratensis L.) sod was established and annually inter‐seeded with perennial ...

A Comparative Field-Scale Simulation Study on Feasibility of SAGD and ES-SAGD Processes in Naturally Fractured Bitumen Reservoirs [PDF]
Energy and Environment Research, 2013 Thermal processes are widely applied in heavy oil and bitumen reservoirs. Steam-Assisted Gravity Drainage (SAGD) and Expanding Solvent-SAGD (ES-SAGD) are the two most promising techniques for production of heavy oil and bitumen reservoirs. The feasibility and efficiency of the aforementioned processes have been studied extensively for sandstone ...

Prediction of Heavy Oil Production Based on Geomechanical Analysis in Entire Lifecycle of SAGD
Energy Science &Engineering, Volume 13, Issue 1, Page 344-354, January 2025.A new mathematical model of crude oil production‐geomechanical coupling was established for three stages of the SAGD life cycle (steam chamber breakthrough stage, rising stage, and lateral dilation stage). The influence of the dynamic evolution of rock porosity and permeability on production was fully considered through the sensitivity coefficient of ...

Impact of stockpiling on soil fungal communities and their functions
Restoration Ecology, Volume 33, Issue 1, January 2025.Fungal communities are important components of soil biology and play crucial roles in multiple ecosystem functions and services; therefore, they can be used as effective indicators of soil function in stockpiled reclamation soils. We profiled the fungal communities of seven stockpiles of different ages (0.5, 1.5, 2, 5, 7, 11, and 28 years old) at ...
