Contemporary spirituality within continuing bonds with the dead is placed into the comparative context of Western Christianity and Japanese Buddhism. Throughout history, humans have maintained interaction with two kinds of dead: ancestors and sacred dead, the first characterized by symmetrical relationships and the second by asymmetrical. Continuing bonds are deeply connected with, and are often in conflict with, bonds to the nation and (in the West) to God. In this framework, the authors find that continuing bonds in the present function within the private sphere and have very limited functions within the larger society, resemble traditional bonds with the sacred dead, and, at this time, offer a mild critique of the values and lifestyles on which consumer capitalism is based.

(-)-Cryptanoside A () was identified previously as a major cytotoxic component of the stems of collected in Laos, which mediates its activity by targeting Na/K-ATPase (NKA), with hydrogen bonds formed between its 11- and 4'-hydroxy groups and NKA being observed in its docking profile. In a continuing investigation, and its 17-epimer, (-)-17--cryptanoside A (), and the new (+)-2-hydroxyandrosta-4,6-diene-3-one-17-carboxylic acid () and the known (+)-2,21-dihydroxypregna-4,6-diene-3,20-dione or 2-hydroxy-6,7-didehydrocortexone () pregnane-type steroids were isolated from . In addition, (-)-11,4'-di--acetylcryptanoside A () has been synthesized from the acetylation of .

The industrial advancement of downstream products resulting from the directed hydrogenation of maleic anhydride is hindered by the limitations related to the activity and stability of catalysts. The development of nonprecious metal intermetallic compounds, in which active sites are adjustable in the local structures and electronic properties embedded within a distinct framework, holds immense potential in enhancing catalytic efficacy and stability. Herein, we report that nickel-based silicides catalysts, RNiSi (R = Ca, La, and Y), afford high efficiency in the selective hydrogenation of maleic anhydride.

Bismuth oxide (Bi2O3) emerges as a potent catalyst for converting CO2 to formic acid (HCOOH), leveraging its abundant lattice oxygen and the high activity of its Bi-O bonds. Yet, its durability is usually impeded by the loss of lattice oxygen causing structure alteration and destabilized active bonds. Herein, we report an innovative approach via the interstitial incorporation of indium (In) into the Bi2O3, significantly enhancing bond stability and preserving lattice oxygen.

Propyrisulfuron, a novel sulfonylurea herbicide, effectively suppresses intracellular acetolactate synthase activity for weed control, but its adsorption behavior in the soil environment remains unclear. To assess potential agroecosystem risks, the adsorption-desorption behavior and mechanism of propyrisulfuron in six typical agricultural soils of China were investigated using a batch equilibrium method, Density Functional Theory (DFT), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy equipped with Energy Dispersive X-ray (SEM-EDX) techniques. It is indicated that the adsorption-desorption of propyrisulfuron in six soils reached equilibrium at 36 hours under the optimum water-to-soil ratio (WSr) of 5:1.

The almost hydrophobic PVDF membrane (PVDF matrix) commonly exhibited excellent performance in pollutant rejection but with poor anti-fouling performance. This study intended to develop the rejection performance and enhance anti-fouling of the PVDF membrane in an O/UF/BAC system for high quality water production through leveraging the advantages of in-situ ozonation and the nature of the PVDF membrane. Reduced density gradient (RDG) analysis demonstrated that the PVDF membrane exhibited excellent ozone resistance by reducing hydrogen bonds and electrostatic interactions between the membrane surface and ozone.
