Macondo was not the first oil spill accident in offshore platforms, and will not be the last either. The resulting explosions and fire led to the deaths of 11 individuals, serious physical injuries to 17 others, the evacuation of 115 individuals from the rig, the sinking of the Deepwater Horizon well, and massive marine and coastal damage from a reported 210 million barrels of released hydrocarbons. Other notable oil spill accident is the explosion of Oil well Ixtoc 1 in the Bay of Campeche in…

THE CONSERVATION STATUS AND DISTRIBUTION OF NILE CROCODILES IN THE OLIFANTS RIVER: MPUMALANGA, SOUTH AFRICA OBSTRUCT The outlook for Nile Crocodiles in the Olifants River does not look optimistic since the increase in capacity of the Loskop and Flag Boshiela Dams, Crocodile population was left with no basking or nesting sites and has and has declined over the past 30 years shortly after the massingire Dam in the Mozambique filled to full capacity an estimated 160 Crocodiles died in the Olifants…

Our industrialized lifestyle leading to climate change is something we can adapt to, but it’s causing a change that the Coral Reefs are not acclimated to live in.The changes and industrializations we bring affects the climate. This problem has been named and clarified as climate change. Since the industrial revolution our climate has changed drastically. Industrial waste is now a necessary problem that collides with our daily life. This lifestyle can be too much for the fragile ecosystems our…

the Fossil Chamber. The Pleistocene fossil vertebrate deposits of Victoria Fossil Cave at Naracoorte area are thought of being Australia's largest and best preserved, and one of the richest deposits within the world. For more than 3000,000 years sediment and animal bones built up within the Fossil Chamber through a gap in the ceiling, forming an enormous cone like pile. The cave acted as a large natural pitfall trap: animals that fell in were unable to flee through the high entrance and died,…

Geologic time periods are often signified by a definite end or beginning event. For most, they end after a catastrophic event such as a volcanic eruption or asteroid collision. For the newest proposed time period, the anthropocene, things may be a little more blurry. There are many factors that may signal the beginning of a new epoch, but no one piece of evidence can say for sure if a new period should be defined or when this period would start. The author, Jan Zalasiewicz’s research has focused…

Berg isolated circular tritium labeled SV40 and λdvgal DNA from infected CV-1 and E. coli cells by equilibrium sedimentation in CsCl-ethidium bromide gradients, respectively. The circular SV40 DNA was then treated with RI endonuclease and found to sediment at 14.5 S in a neutral sucrose gradient. The linear SV40 DNA was then treated with λ exonuclease to remove deoxymononucleotides from the 5’ terminus, resulting in the complementary 3’ end being…

4. RESULT AND DISCUSSION 4.1 Introduction In this chapter, all the results and analysis in this experiment that have been performed are discussed in detailed. The analysis included characterization and optimization. In addition, the graph and table were prepared to better present the results. 4.2 Extraction Of Jatropha Curcas By Using Soxhlet Extraction Method And Microwave Extraction Method The extraction of Jatropha curcas can be done through many methods such as mechanical extraction,…

I found the content of his sediment to be very emotional and sometimes disturbing. Emotions are most expressed through a person's hands and face. In the Hiroshima project, Krzysztof brings Hiroshima survivors, and projects their hand gestures onto the one of standing building from…

Crabs are a type of crustacean that occur within mangrove ecosystems and can be found from high tide through to low tide levels. Crabs shelter underneath logs and in cool places to avoid drying out and many create burrows for refuge from larger prey, it can also be the site of mating and incubation. Other crabs use burrows to store their food as the water tide rises or lowers. Red fingered marsh crabs and fiddler crabs are commonly active at low tides where they are often out looking for food,…

have lower abrasion resistance than expected. Limestone Limestone is a sedimentary rock composed essentially of calcite, a mineral of calcium carbonate. The formation processes of limestone differ substantially in the origin of the constituents sediments: these may result (organogenic limestones) from shells or exoskeletons. They can also be formed by the chemical precipitation of salts dissolved in water (chemogenic limestones). Finally they may come from the degradation of existing…
