Q. 995) What do you understand by annealing
XAnnealing, in metallurgy and materials science, is a heat treatment wherein a material is altered, causing changes in its properties such as strength and hardness. It is a process that produces conditions by heating to above the recrystallization temperature and maintaining a suitable temperature, and then cooling. Annealing is used to induce ductility, soften material, relieve internal stresses, refine the structure by making it homogeneous, and improve cold working properties.

Q. 997) Working principle of the dgps
Xdifferntial gps
it is fixed station whose position is known
it recives its position from the satellite and calculates the error between two positions and then it transmits the error for that satellite
brendon n kamlesh
it has a fix position and it compared with 3 satellite position and compare with own position and diffrence will be find out,and transtmit the difference in all vessels are uhf range
Q. 998) Wht do you understand by angle of repose
X
it is the angle btw horizontal plane and the cone slope optained when bulk cargo is loaded on this plane
when the bulk cargo is loaded on board.,to a large amount,it forms a shape of slope.
So the angle between the horizontal area and the slope formed by cargo is called angle of repose
Q. 999) What is Muster list ?
XQ. 1000) What do you understand by t & p notices
X
temporary notice are given when some information exist on chart for some short time . and prelimry notice are given when in future there will some work will take place in future
both are related to notices to mariner ,, both are temperary warnings ,, and hence the related corrections are done in pencil on the chart.
temporary and preliminary notices to mariner....
temporary notices are the information that remains remains temporary usually not more then 3 months and preliminary notices are the notices that are at their preliminary stages nd can be permanent at a later stage....such as extension of any port, contruction of any bridge...etc
