Synthesis of reactive iron Chemical reduction method of Ferric chloride by sodium borohydride following reaction (Eq.1), was used to synthesize ZVI [14]. 〖2FeCl〗_3+〖6NaBH〗_4+〖18H〗_2 O→〖2Fe〗^0+〖21H〗_2+〖6B(OH)〗_3+6NaCl (1) Ferric chloride hexahydrate solution was prepared by dissolving 5 g of FeCl_3.H_2 O (99.0%, Junsei Chemical Co., Japan) in 125 mL of deoxygenated deionized (DI) water. Moreover, 3.5 g of Sodium borohydride (NaBH_4, 98.0%, Sigma–Aldrich Inc., USA) were dissolved in 125 mL…

“Lunch,” she proclaimed holding up a basket. Smith and Andre quickly joined her. “It’s the peasant woman’s,” she explained. They all stared into the basket. Cradled against its bottom were two long loaves accompanied by two equally long bottles. On the top, about the size of a man’s fist was something wrapped in wax paper and tied with string. Julia touched it with her fingertips, “Cheese,” she said. They descended and sat beneath the hedgerow munching on the crusty bread and breaking off lumps…

Orca whales that were captured and delivered to their lifelong home in SeaWorld amusement parks went from swimming up to 100 miles a day to being put in tanks that are much too small for them.

The multitude of stressors also causes these cetaceans to purposely hurt themselves, ramming and banging their heads on their tank…
