Abstract As calcareous foraminifera precipitate their shells from the surrounding water mass, they are the basis of most marine radiocarbon chronologies and paleo-proxies.Nevertheless, post-mortem alteration of shells, especially addition of authigenic calcite, impact proxy records.In the Arctic Ocean, Breadboards authigenic calcite overgrowth on f
Reappearance of change in time of rotation axis with simulation in baseball-type acceleration sensor
We develop an output simulator for a baseball-type acceleration sensor in which one three-axis sensor for low acceleration and three sensors for high acceleration are installed.The acceleration vector at any position inside this ball-type sensor in rotational motion is formulated on the basis of the assumption that all the sensors are in rigid conf
Diseases of the Date Palm: Present Status and Future Prospects
While date palm is affected by many diseases, bayoud remains the most serious one.It is caused by a soil born pathogen, Fusarium oxyspurum f.sp.albedinis.It has affected practically all Moroccan palm groves as well as those of western and central Algerian Krumkake/Pizzelle Irons sahara, where it has respectively killed more than 12 million in Moroc
The resting cyst of dinoflagellate Scrippsiella acuminata host bacterial microbiomes with more diverse trophic strategies under conditions typically observed in marine sediments
Variation in the condition of marine sediments provides selective preservation milieus, which act as a key determinant for the abundance and distribution of dinoflagellate resting cysts in natural sediments.Microbial degradation is an understudied biological factor of Curtain/Screen/Blanket potential importance in the processes.However, gaps remain
