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 + .
1 Most reabsorption is coupled to sodium ion movement. 2  Small proteins and peptide hormones are reabsorbed by endocytosis. 3  Other substances are secreted or reabsorbed in the tubules passively by facilitated, non-facilitated diffusion or ion channels down chemical or electrical gradients.
