41. Another model proposes that dark slope streaks are produced by ground-hugging adsorbed onto subsurface grains. 42. At temperatures as low as 150 �C resistivity will decrease due to release of physically adsorbed hydrogen. 43. Shales however, are naturally radioactive due to potassium isotopes in clays, and adsorbed uranium and thorium. 44. Such cooperation is proven by calculating the adsorption probability of flowing vWF once it crosses another adsorbed one. 45. The graphene sheets are adsorbed to the high energy interface between the materials and are kept from restacking. 46. The tissue self-adheres in a short period and the air is adsorbed into the surrounding tissues. 47. Moisture may be present as adsorbed moisture at internal surfaces and as capillary condensed water in small pores. 48. Second, how to determine the total amount in the adsorbed phase based on experimentally measured equilibrium data. 49. This residue then bonds to other ?-lg proteins, including those already adsorbed to the surface. 50. This structure is similar to hydrogen adsorbed graphene ( graphane ) and fluorine adsorbed graphene ( fluorographene ).
