Q: Different type of Fusion splicer: A: The principle of fusion splicer is same, Single core optical fiber welding machine can fuse a single core each time; Ribbon fiber Fusion splicer used for weld ribbon fiber, able to splice 2/4/6/8/12 cores onece. Q: Which type Fiber Fusion Splicer welding speed is most fast.
1 Sodium absorption by the distal tubule is mediated by the hormone aldosterone. 2  Aldosterone increases sodium reabsorption. 3  Sodium and chloride (salt) reabsorption is also mediated by a group of kinases called WNK kinases. 4  There are 4 different WNK kinases, WNK1, WNK2, WNK3, and WNK4. It regulates pH by absorbing bicarbonate and secreting protons (H +) into the filtrate, or by absorbing protons and secreting bicarbonate into the filtrate. 2  Sodium and potassium levels are controlled by secreting K + and absorbing Na + .
Water reabsorption is a passive process: water is reabsorbed by osmosis. In most of the nephron, water reabsorption is unregulated and coupled to solute reabsorption.The ability to excrete urine that is more concentrated than the extracellular fluid (ECF) depends on the creation of a hyperosmotic environment in the medulla.As the collecting duct descends through the medulla, the increasing osmolarity in the interstitial fluid drives water reabsorption.he ability to excrete urine that is more concentrated than the extracellular fluid (ECF) depends on the creation of a hyperosmotic environment in the medulla.
