2. Integrated Experimental Approach for Alloying of Surface Layer Ti6Al4V+B4C Metal Matrix Composites using Laser Treatment
Surface engineering applications have brought the titanium and its alloys into the limelight in the manufacturing industries such as the aerospace, automobile, marine, chemical processing industry, nuclear power and biomedical. Despite the growths experienced in the use of this material, it is plagued with poor wear behaviour, especially when in contact with

3. Barium and its Importance as an Indicator of (Paleo)Productivity
ABSTRACT Barium (Ba) is a trace element which occurs predominantly as barite mineral (BaSO4) in the marine environment. Previous work suggests that barite concentrations are related to the organic carbon flux and marine biological debris in the water column suggesting a direct or indirect involvement in the marine biological cycling. In addition, barite has

4. Ecologia e Conservação de Tartarugas Marinhas Através da Análise de Encalhes no Litoral Paraibano
Five sea turtle species use the Brazilian coast for reproduction and feeding: loggerhead turtle (Caretta caretta), green turtle (Chelonia mydas), leatherback turtle (Dermochelys coriacea), olive turtle (Lepidochelys olivacea) and hawksbill turtle (Eretmochelys imbricata). These species are included in the threatened categories, as much globally, according to

5. ResÃduos sÃlidos bentÃnicos em ambientes recifais de Pernambuco e na abordagem das operadoras de mergulho
Benthic marine debris are those debris deposited on the bottom of the oceans. Studies of this type of pollutant are still scarce all over the world, both about the qualiquantification, as well as about the understanding of how social actors linked to the marine environment are behaving on this issue. Thus, this study aimed to qualiquantify the benthic marine

6. ImplicaÃÃes de fatores ambientais na deposiÃÃo de plÃsticos no ambiente praial de um ecossistema estuarino
Marine debris are materials from anthropogenic sources, such as plastics, paper, glass, wood and others, that enter the marine and coastal environments from multiple sources, and are considered as one of the most important marine pollutants by the turn of the XXI Century. Sandy beaches are usually more studied because they are relatively easy to be monitored

7. Pedological characterization of Brazilian archaeo-anthroposols: sambaquis from the lakes region (RJ) and indian dark earths from the low Negro/Solimões river region (AM) / Caracterização pedológica de arqueo-antropossolos no Brasil: sambaquis da Região dos Lagos (RJ) e terras pretas de índio na região do baixo rio Negro/Solimões (AM)
This work surveyed some anthropogenic soils, the so-called Archaeo-Anthroposols. Those soils show advanced degree of pedogenesis, displaying tokens of their anthropic origin such as chemical and mineralogical characters and soil micromorphology. Some pottery shards are also constantly found in places where pottery making peoples dwelt, as well as shells and
