Planning And Operation Problems Of Indian Major Ports With Special Emphasis On Cochin Port

Rapid changes in the technological environment of marine logistics and the increasing integration of waterborne, air and land transport systems have fostered a revolution in the design and operations of transport vehicles, cargo handling technology, and terminal facilities. This in turn has caused major changes in the functions of and uses of ports. From literature, it was found that these changes were very slow in case of Indian ports and the performances of port operations were poor when compared with similar ports in the same region. It was also found that a very few studies were conducted to identify the reasons for slow improvements in the performances of Indian major ports. In this thesis, an attempt is made to find out the operational problems of Indian major ports and to analyze the reasons for it. Some solutions have also been found out using management tools

Caracterização hidrodinâmica e morfo-sedimentar do estuário Potengi e áreas adjascentes: subsídios para controle e recuperação ambiental no caso de derrames de hidrocarboneto

This study presents the Environmental Sensibility Mapping to oil spillings on the Potengi estuary - RN and neighboring coastline through remote sensing data, collecting, treatment and integration of the geomorphologic, oceanographic (temperature, salinity, density, direction and intensity), meteorological (wind speed and direction) and high resolution seismic (bathymetry and sonography) data. The Potengi river estuary is located on the eastern coastline of the Rio Grande do Norte State, being inserted in the geological context for the coastal Pernambuco-Paraíba basin and spreading over 18 km; it shelters the Natal harbor zone and an oil terminal, centralizing, therefore, important oil transport operations that can cause accidental spillings. Under the oceanographic point of view, the Potengi estuary is characterized by the absence of any expressive thermic stratification, being classified as partially mixed, B type according to Pritchard (1955), and 2 type in conformity to the stratification-circulation diagram by Hansen & Rattray (1966). Two main wind systems are responsable for the formation of wave sets that occur in the area. The dynamic tide presents, in the Natal Harbor, mean amplitude in spring and quadrature tides, with around 2.8 and 2m, respectively. The mechanism of saline tide mixing was defined through the salinity which is the main parameter for the identification of this mechanism. Important variations of the salinity mean values (36.32 psu), temperature (28.11ºC) and density (22.96 kg/m3) in the estuarine waters presented features belonging to low latitude regions. The water temperature follows the air temperature variations, in the region, with expressive daily amplitudes. In this study, the identification of the estuarine bed morphology through bathymetric and sonographic analysis, had the purpose to evaluate the influence of the superficial and bottom currents for the bottom shaping. In this way, the use of the side scan sonar showed, to be very useful in the identification of the bottom morphology and its relationship with the predominant action of the tidal currents in the Potengi estuary. Besides, it showed how the sonograms can be a support to the comparison of the several patterns derived from the local hydrodynamic variations. The holocene sediments, which fill the estuarine channel, are predominantly sandy, varying from selected, sometimes silty. The sedimentation is controlled by the environmental hydrodynamic conditions, being recognized two important textural facies: Muddy Facies and Sandy Facies. The distribution of these textural facies apparently oscillates owing to the tidal cycle and flow intensity. Each one of the above mentioned data was integrated in a Geographic Information System (GIS), from which was produced the Environmental Sensibility Map to oil spillings with Coastal Sensibility Index (CSI) to the Potengi estuary. The integrated analysis of these data is essential to oil spilling contingency plans, in order to reduce the spilling environmental consequences and to make efficient the endeavours of contention and cleaning up/removal on the Natal Harbor. This study has the aim to collaborate for the increase of informations about the estuarine environment and contribute to a better management of the question: environment/polluting loads

Integrated assessment of multilevel biomarker responses and chemical analysis in Mussels from Sao Sebastiao, São Paulo, Brazil

The aim of the present study was to investigate the presence of contaminants in the mussel Perna perna from Sao Sebastiao Channel, São Paulo, Brazil, and to evaluate the effects of these contaminants on these organisms at biochemical (catalase [CAT], glutathione-S-transferase [GST], and cholinesterase [ChE]), cellular (neutral red retention time [NRRT] assay), and physiological (cardiac monitoring) levels. Two sampling surveys were performed (winter of 2001 and summer of 2002) at six stations along the channel: Cigarras, station 1; late Clube de Ilhabela, station 2; Oil Terminal, station 3; Toque Toque, station 4; Ponta da Sela, station 5 (reference station); and Taubate, station 6. Differences in CAT activity were observed between mussels from stations 3 and 5 during the winter, but no differences were detected in the summer. No differences in GST activity were found among stations during the winter, although animals from station 3 showed higher activity during the summer. The ChE activity was significantly higher in the mussels from stations I and 2 during the winter and from stations I and 3 during the summer. Organisms from stations I through 4 showed statistically lower NRRT in both seasons. Similar heart rates were observed in the mussels from all stations. Hydrocarbons were detected in organisms from all the stations in both seasons. During the winter, higher polycyclic aromatic hydrocarbon (PAH) levels were observed in organisms from station 3, whereas during the summer, higher levels of metals were found in organisms from stations 1, 3, and 4. The multivariate analyses showed a strong influence of PAHs on the winter biological results, but metals showed higher influence on these responses in the summer, indicating multiple contaminant sources.

Chronic contamination assessment integrating biomarkers' responses in transplanted mussels-A seasonal monitoring

This study aimed to provide the first biomonitoring integrating biomarkers and bioaccumulation data in Sao Paulo coast, Brazil and, for this purpose, a battery of biomarkers of defense mechanisms was analyzed and linked to contaminants' body burden in a weigh-of-evidence approach. The brown mussel Perna perna was selected to be transplanted from a farming area (Caraguatatuba) to four possibly polluted sites: Engenho D'Agua, DTCS (Dutos e Terminais do Centro-Oeste de Sao Paulo) oil terminal (Sao Sebastiao zone), Palmas Island, and Itaipu (It; Santos Bay zone). After 3 months of exposure in each season, mussels were recollected and the cytochrome P4501A (CYP1A)- and CYP3A-like activities, glutathione-S-transferase and antioxidants enzymes (catalase, glutathione peroxidase, and glutathione reductase) were analyzed in gills. The concentrations of polycyclic aromatic hydrocarbons, linear alkylbenzenes, and nonessential metals (Cr, Cd, Pb, and Hg) in whole tissue were also analyzed and data were linked to biomarkers' responses by multivariate analysis (principal component analysisfactor analysis). A representation of estimated factor scores was performed to confirm the factor descriptions and to characterize the studied stations. Biomarkers exhibited most significant alterations all year long in mussels transplanted to It, located at Santos Bay zone, where bioaccumulation of organic and inorganic compounds was detected. This integrated approach using transplanted mussels showed satisfactory results, pointing out differences between sites, seasons, and critical areas, which could be related to land-based contaminants' sources. The influence of natural factors and other contaminants (e.g., pharmaceuticals) on biomarkers' responses are also discussed.

Vanadium biomonitoring by using Perna perna (Linnaeus, 1758) mussels transplanted in the coast of the State of So Paulo, Brazil

The increased pollution in the aquatic ecosystem has led to the investigation of toxic elements in sea water by using marine organisms to assess marine pollution from human activities. Among these organisms, the mollusks bivalves have been used as biomonitors since they can accumulate trace elements and other substances, without the occurrence of their death. In this study, Perna perna mussels were transplanted from a mussel farm (reference region) to four sites located in coastal regions of So Paulo State, Brazil, close to anthropic discharge areas. Vanadium was determined in mussel tissues by instrumental neutron activation analysis (INAA). Quality control of V analysis was checked by analyzing biological reference materials and the results obtained were precise and in good agreement with the certified values. Comparisons between the V concentrations obtained in transplanted mussels indicated that those from So Sebastio region, close to an oil terminal presented the highest concentration of this element, during spring.

A manutenção industrial tem ganho cada vez maior importância nas empresas. As exigências atuais obrigam os responsáveis pela manutenção a procurarem novas formas de organização, utilizando técnicas e metodologias que são normalmente utilizadas na gestão de outras áreas funcionais de empresas A presente dissertação foi elaborada no seguimento de um estágio profissional no âmbito da gestão das operações e manutenção de uma empresa do ramo petrolífero. O terminal petrolífero da Trafaria é uma instalação de comercialização, distribuição e armazenagem de produtos de origem petrolífera. Procurando sempre a melhoria do serviço de manutenção fornecido atualmente, esta dissertação busca investigar e intervir nos pontos em que seja possível uma melhoria do atual sistema de gestão da manutenção. No decorrer da avaliação das atividades da manutenção foi analisado o sistema atual de gestão da manutenção, bem como as diversas reparações efetuadas no dia-a-dia da instalação, com o objetivo de compreender o funcionamento do serviço da manutenção e quais as necessidades da instalação. É nos pontos que se evidenciaram como oportunidades de melhoria que se pretendeu atuar, otimizando o serviço da manutenção, e reduzindo ou eliminando os problemas identificados. Um outro foco de atenção do estudo esteve relacionado com a implementação de novas técnicas de manutenção industrial, nomeadamente, a Manutenção Produtiva Total e a Metodologia 5S. Foram desenvolvidos procedimentos e/ou planos de inspeções que sustentam os novos métodos implementados. Também é de salientar a implementação de uma nova aplicação informática de gestão da manutenção, acompanhada de uma revisão e reestruturação do plano de manutenção do terminal. Na realização desta tarefa foram revistas todas as intervenções e ordens de trabalho preconizadas pelo plano de manutenção. Algumas das melhorias propostas já foram implementadas, outras encontram-se em processo de implementação ou serão implementadas a médio/longo prazo. A implementação destas medidas vai permitir ao terminal ganhos significativos tanto ao nível quantitativo (utilização mais racional de todos os recursos) como também qualitativo (aumento da motivação, segurança e disciplina organizacional).

Origin of oil in the Wilmington field in California

No presente trabalho, o autor trata da formação de campo petrolífero que se teria formado às expensas de organismos planctónicos, misturados com areia das dunas, material esse que teria sido transportado pelo vento. Refere-se, assim, o autor, ao campo petrolífero de "Wilmington", situado na Ilha Terminal, ao sul de Los Angeles, California. Esse campo, que já fora descrito, em 1943, por GILLULY & GRANT, faz parte do Mioceno e do Plioceno inferior, achando-se separado dos schistos Jurássicos metamórficos, por uma discordância localizada a 6.000 pés de profundidade. O conjunto das camadas petrolíferas alcança espessura de 1 .500 pés, sendo cada uma delas separada das outras por estratos do "siltstone" (siltito). O tamanho dos grãos, nos dois tipos de rochas, é o de depósitos eólicos, mas, ao contrário do que acontece em depósitos sub-aéreos, esses grãos são angulosos ou sub-angulosos. De acordo com MCNAUGHTON , esses depósitos se teriam formado em profundidade crescente, de 200 a 5.000 pés; esse fato, relacionado com as dimensões dos grãos, leva a crer que o material tenha sido transportado pelo vento. A sedimentação deu-se longe da costa, de maneira muito lenta, provavelmente em consequência de tempestades de excepcional intensidade. O petróleo teria sido produzido por organismos planctónicos que se teriam misturado com areia das dunas, sendo a velocidade da sedimentação desta, muito menor. Os cálculos indicam que foram armazenados somente 23% dos hidrocarbonetos que caíram sobre a areia de sedimentação, sob a forma de organismos mortos. M. V.

Short-term exposure of mice to cigarette smoke and/or residual oil fly ash produces proximal airspace enlargements and airway epithelium remodeling

Chronic obstructive pulmonary disease (COPD) is associated with inflammatory cell reactions, tissue destruction and lung remodeling. Many signaling pathways for these phenomena are still to be identified. We developed a mouse model of COPD to evaluate some pathophysiological mechanisms acting during the initial stage of the disease. Forty-seven 6- to 8-week-old female C57/BL6 mice (approximately 22 g) were exposed for 2 months to cigarette smoke and/or residual oil fly ash (ROFA), a concentrate of air pollution. We measured lung mechanics, airspace enlargement, airway wall thickness, epithelial cell profile, elastic and collagen fiber deposition, and by immunohistochemistry transforming growth factor-β1 (TGF-β1), macrophage elastase (MMP12), neutrophils and macrophages. We observed regional airspace enlargements near terminal bronchioles associated with the exposure to smoke or ROFA. There were also increases in airway resistance and thickening of airway walls in animals exposed to smoke. In the epithelium, we noted a decrease in the ciliated cell area of animals exposed to smoke and an increase in the total cell area associated with exposure to both smoke and ROFA. There was also an increase in the expression of TGF-β1 both in the airways and parenchyma of animals exposed to smoke. However, we could not detect inflammatory cell recruitment, increases in MMP12 or elastic and collagen fiber deposition. After 2 months of exposure to cigarette smoke and/or ROFA, mice developed regional airspace enlargements and airway epithelium remodeling, although no inflammation or increases in fiber deposition were detected. Some of these phenomena may have been mediated by TGF-β1.

Hidrocarbonetos policíclicos aromáticos em sedimentos e organismos bentônicos do Terminal de Miramar (Baía do Guajará - Belém - Pará - Amazônia)

ABSTRACT: In Guajará bay, mouth of the Amazon River, is located the capital of Pará state (Belém) and its metropolitan area. Exists in this area an intense boat traffic, as well as transportation and sale of fuels in floating docks and activities related to the storage and transportation of oil in Miramar Petrochemical Terminal (TEMIR). Small spills and discharges of oil in water can serve as sources of pollution by polycyclic aromatic hydrocarbons (PAHs). PAHs are organic compounds generated by incomplete combustion of organic matter (OM) and are among the contaminants of most interest in environmental studies due to their mutagenic and carcinogenic potential. One way to detect and evaluate the impact of PAHs in an environment is using biomonitors, however the qualitative and quantitative analysis in sediments are most widely used. This study aimed to evaluate, by Gas Chromatography/Mass Spectrometry (GC/MS), the 16 PAHs considered as priority by the Environmental Protection Agency of the United States in sediments and benthic organisms (Namalicastys abiuma) of TEMIR. Field expeditions were carried out in December 2012, March, May and June 2013 representing the dried, wet (two samples) and dried seasons successively. Fine sediments levels dominated in both sampling periods and the %Fines in Guajará bays has a direct relationship to the %OM. In relation to the 16 PAHs studied, 10 of them were detected in the wet season sediments samples and 8 in the dried season. Even with a low diversity of aromatic compounds, sediment samples of the dried season presented greater ΣHPAs (1.351,43 ng g^-1) than the sediments of the wet season (263,99 ng g^-1), which can be related to the increased hydrodynamic in Guajará bay this last period. Correlation analysis indicated that ΣHPAs not seem to be influenced by %Fine and %OM. Benzo(a)pyrene accounted for 87% of ΣHPAs during the wet season, the other PAHs showed percentage ≤ 3%. During the other period stood out: pyrene (18% of ΣHPAs) fluoranthene (16%), the chrysene, benzo(b)fluoranthene (15%) and benzo(a)pyrene (11%). The use of the geochemical reason to interpret likely sources of PAHs indicated that there is a predominance of aromatics from pyrolytic origin in TEMIR. The activities that may be responsible for the PAHs levels observed in sediments and benthic organisms in TEMIR are the discharge of untreated domestic sewage and the emissions of particulates from cars and small/medium boats. The ΣHPAs seems to influence the density of polychaetes because a reduction of about 50% in the number of organisms was observed during the dry season when there was the greater amount of ΣHPAs in their body structure. Among the 16 PAHs studied, 11 were detected in the polychaetes during the dry season (ΣHPAs_MED = 848,71 ng g^-1) and 10 in the wet season (ΣHPAs_MED = 141,85 ng g^-1). Were highlighted during the dried season: indeno(1,2,3-c,d)pyrene (47%) and pyrene (23%). While in the wet season: pyrene (23%), chrysene (17%), fluorene (17%) and fluoranthene (13%). The %Rec obtained was >>100% indicating a matrix effect and reducing the quantitative accuracy of results. The use of the polychaete N. abiuma as biomonitor of pollution by PAHs in estuaries not seem to be effective when the sample period is limited, because collecting it requires a great effort to obtain a small amount of mass and it still results in a matrix effect in the chromatographic analysis (method %Rec >> 100%) that may not be corrected due to the restricted availability of sample mass. Studies with a larger number of samples, enabling depth statistical analysis, and covering other collection points in Guajará bay are required to prove mathematically that has been stated in this dissertation.
