About the issue of the theory of screw hole-borers.

Tarverdyan, A., State Agrarian University of Armenia [2009]

The article deals with the problems of specifications in the theory of optimization of geometrical parametrs and operating regimes of screw hole-borers. The minimum permissible angular speed of screw rotation and the period for transition process of eart handling speed in case of normal regime are defined with the help of the obtained formulas. The developed theory allows to define the paramet ...

Analitical method of designing rotating mouldboard.

Karahanyan, K., State Agrarian University of Armenia et al. [2009]

Turnwrest, shuttle ploughs and ploughs with rotating mouldboards are used for single-sided tillage of landson slopes. Usually turnwrest and shuttle ploughs have two bodies turning right and left. Therefore the mentioned ploughs have one common shortcoming large mass, that's why the stability of the unit decreases with the increase in slope steepness. From that viewpoint it is reasonable to use ...

Substantiation of designing and calculation of drip irrigation systems.

Abbasi, E., State Agrarian University of Armenia et al. [2009]

The pricipals of design and calculation of drip irrigation are of great interest for Armenia and Iran in viewpoint of water resources effective management. Drip irrigation reduces deep percolation and evaporation.It also allows to achieve irrigation efficiency up to 90%. A succesful designing largely depends on the quality and quantity of water resources.
