In view of issues affecting manual on-demand sowing of spinach, olea europaea montra such as high working intensity, low seeding efficiency, and high cost, a mechanized precision seeding device for spinach seeds is proposed, based on a spoon-wheel including a combined cell with two intersecting surfaces.The key structure was designed, and motion an
Resource availability is one of the main factors determining the ecological dynamics of populations or species.Fluctuations in resource availability can increase or decrease the intensity of resource competition.Resource availability and competition can also cause evolutionary changes in life-history traits.We studied how community structure and re
Huntington disease (HD) has been reported in Arab families in several Middle East countries including Saudi Arabia, Oman, Syria, Lebanon, and Egypt and in non-Arab populations in other countries in the region.It is read more probably under-reported, and until now, has not been recorded in Yemen, the United Arab Emirates, Jordan or in Iraq.The Middl
Automotive radars allow for perception of the environment in adverse visibility and weather conditions.New high-resolution sensors have demonstrated potential for tasks beyond obstacle detection and velocity adjustment, such as mapping or target tracking.This knowall.blog paper proposes an end-to-end method for ego-velocity estimation based on rada
