input on tensile strength‚ toughness‚ micro hardness‚ micro structure and corrosion behavior of duplex stainless steel joints. Four parameters were varied by keeping speed as constant. The heating pressure of 30‚ 40‚ 50 MPa‚ heating time of 3‚ 4‚ 5 sec‚ upset pressure of 60‚ 70‚ 80 MPa‚ upset time of 2‚ 3‚ 4 sec were used to weld the joints. L9 orthogonal design concept was used. Results revealed that no intermetallic phases were formed. By increasing the heat input the tensile strength of the joint

We’ve all heard it before‚ "Exercise is good for you because...." Nowadays you can’t check out at the grocery store or do much of anything without being reminded that we mortal humans need to exercise. Still‚ we persist‚ procrastinate and eventually complain that we’re overweight‚ sick‚ dying‚ etc. Listen. Some exercise is better than none‚ more exercise is generally better than less‚ and no exercise can be disastrous. No one is asking for you to start a rigorous daily regimen‚ just do something

The production of silk is very important. First‚ strength of silk. Second‚ the stickiness of silk. Last‚ the production of silk. The strength of silk can keep bugs from breaking through. It also prevents them from falling down. The strength of it also prevents snapping randomly. Dragline silk consists of proteins called spidroins. These are
