Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

open access: yesGeological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

open access: yesJournal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.

Research on Fractures in Hydraulic Fracturing Reservoirs

open access: yesAcademic Journal of Science and Technology
 Hydraulic fracturing is an important technology for unconventional natural gas extraction. It generates volume opening in the reservoir by injecting a fluid volume exceeding the reservoir's pore elasticity, thus opening up migration channels for free gas.

Sanitary risk in the handling of home‐prepared enteral formulations: A cross‐sectional assessment of microbiological contamination and food safety

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Studies show increased use of home enteral nutrition (HEN) owing to its benefits. However, knowledge about the sanitary risks of handling home‐prepared formulas remains limited despite their high contamination rates. This study aimed to assess the sanitary risks in the handling of home‐prepared enteral formulations by analyzing ...

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

open access: yesNear Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Reservoir Simulation in Heterogeneous and Fractured Reservoirs

open access: yes, 2018
Summary of the thesis This thesis addresses simulation of flow and transport of fluids and fluid components in heterogeneous and fractured porous media. Reservoir simulation is a key component in several engineering applications, such as oil recovery, groundwater hydrology, nuclear waste disposal, and geological CO2 storage.

Negative Stiffness Induced and Controlled by Constriction

open access: yesphysica status solidi (b), EarlyView.
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).
