OCEANOGRAPHIC CHARACTERISTICS OF CAMAMU BAY (14◦S, BRAZIL) DURING DRY AND WET CONDITIONS

Xenomas in Crassostrea rhizophorae (Ostreidae) from Camamu Bay, Bahia, Brazil.

50 m 50 m This paper reports the occurrence of xenomas in the mangrove oyster Crassostrea rhizophorae (Guilding, 1828) gills. Xenomas are formed when intracellular parasites accumulate within host cells, causing hypertrophy of the cell and its nucleus. In fish, the xenomas are commonly caused by microsporidians (Matos et al., 2003), but in the oyster Crassostrea virginica (Gmelin) they are caus...

Parasites of the mangrove mussel Mytella guyanensis (Bivalvia: Mytilidae) in Camamu Bay, Bahia, Brazil.

This contribution reports the parasites found in the mangrove mussel Mytella guyanensis in Camamu Bay, Bahia, Brazil. Samples were collected monthly from September 2006 through October 2007. A total of 460 individuals were collected, fixed in Davidson's solution, and processed by standard histological techniques, and the sections were stained with Harris hematoxylin and eosin (H&E). The water t...

Oceanographic Characteristics of Baía De Todos Os Santos, Brazil

Effect of Wet and Dry Conditions on Wear Behavior of Amorphous Coating of Fe-Cr-Mo-Nb-C-B

Recently, wear resistant properties of metallic glasses has attracted a lot of interest. Because the surface of metallic glasses are prone to phase transformation, finding the effects of test condition on structure and wear behavior of metallic glasses is important. In this research, by using an automated electrospark deposition (ESD), a layer of Fe51Cr18Mo7B16C4Nb4 was deposited on AISI 316l s...
