The Research is entitled “Design, Fabrication and Performance Testing of Directional Control Valve for Control of Multiple Actuators”. An indexing unit is a direction control valve used in Hydraulic system. This device shall be named ‘Bharath Valve’ (US10180190), as is the name of its Inventor. This valve can control more than one number of actuators. This valve consists of a hollow outer cylinder and inner cylinder. The inner cylinder fits in the hollow portion of outer cylinder; this inner cylinder is operated manually. The rotation of the inner cylinder inside the outer cylinder changes the direction of flow of liquid through the valve this control the movements of actuator. This Indexing valve can become a highly advantageous replacement of the conventional Spool valves that are used for controlling the actuator. In the present scenario one spool valve can control only one actuator thus the number spool valves used in a hydraulic system is equal to the number of actuators. However ‘Bharath’ valve can control more than one number of actuators, this in turn makes the number of system components less and also reduces the overall cost of hydraulic system. Even the controlling of movement of actuators can be easy. A computer interface if given can make this valve versatile and a very cheap alternative to the existing valves, taking number of components, construction, friction and efficiency into account. This research proves that ‘Bharath’ valve has more advantages than that of existing ones and some of the advantages are listed below,  One valve can control more than one actuators thus reduces the number of valves.  Construction of this indexing valve is simpler and parts involved in friction is less.  Reduction in the cost of manufacturing is highly significant.  This valve makes it possible to actuate the desired cylinder keeping the other at rest.  The modification in operating actuators of system can be easily changed by operating ON/OFF flow valve connected to the inlets of Indexing valve.

How to realize the pressure-resist and seal of the components is the key point for the development of the deepsea hydraulic manipulators. In this paper, a novel hydraulic system with the outer-inner pressure balanced technique is presented. Another key problem is that oil supply could not provide enough oil for the actuators when the joints are operated simultaneously. So, an electro-hydraulic digital flow distribution method based on meter-in flow feedback for multiple actuators load sensing system is put forward to distribute flows when two or more actuators are operated together. The corresponding theoretical principle is analyzed and the performances are evaluated through simulations.

Conflict Escalation

Conflicts can be dangerous or may even benefit a relationship, depending on how they are resolved. Because conflict creates strong emotions, emotions are not suitable as a basis for constructive problem solving. Conflict escalation rarely benefits a relationship, especially if it creates selfishness, stubbornness, and withdrawal from relationships. What's worse, conflicts can lead to physical disputes and actual violence, a community can work together, but it can be that at other times the community that has worked together can turn into social conflict. Conversely, people who initially conflict can change to work together for a certain time. For that social processes that occur are very dynamic, these conditions are very dependent on the power management model that runs in the community concerned thus interpreting the conflict based on the causes of conflict are: specific behaviors, norms and personal roles and dispositions. Conflict can also occur in the name of religion, caused by several factors including: superficial religious knowledge, fanaticism, religion as a doctrine, symbols, religious figures, history, fighting for surge.
