PERTUMBUHAN SEMAI SENGON DAN MANGIUM PADA TANAH PADAT

open access: yesJurnal Ilmu Pertanian Indonesia, 2010
The research was conducted to examine the seedling of mangium (Acacia mangium and sengon (Paraserianthes falcataria) on compacted soil. Soil was compacted with a proctor test at the different level of bulk density (0.9;1.0; 1.1; 1.2; 1.3 g/cm3) with 10 ...

The Osteoblastic Microenvironment Determines the Fate of Breast Cancer Cells Disseminated in the Bone Marrow

open access: yesAdvanced Science, EarlyView.
This study revealed how the osteoblastic microenvironment determines the fate of cancer cells disseminated in bone, with a focus on whether they colonize, reside in quiescence, or reactivate from dormancy. Targeting integrin signaling may offer promising strategies for preventing quiescent cancer cells reactivation and bone colonization.

Textural soil bulk density. II. - Result and discussion

open access: yes, 1981
La recherche de relations entre la densité texturale des sols et leur composition granulométrique est réalisée sur des échantillons de sols naturels considérés à l’état sec. Il apparaît que la densité texturale croît avec la teneur en argile 0-2 μm, quand cette teneur est comprise entre 10 et 50 p. 100.

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota

open access: yesAdvanced Science, EarlyView.
This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Long‐Term Active Rather than Passive Restoration Promotes Soil Organic Carbon Accumulation by Alleviating Microbial Nitrogen Limitation in an Extremely Degraded Alpine Grassland

open access: yesAdvanced Science, EarlyView.
Active restoration increases soil organic carbon stocks by reducing microbial nitrogen limitation. Nitrogen availability promotes particulate to mineral‐associated organic carbon conversion by reducing microbial carbon use efficiency. Passive restoration has no effect on soil organic carbon stocks.
