Water supply and sanitation is a problem in developing nations as they lack the proper resources to install a water collection foundation. Bolivia can be considered a developing nation that has a water supply problem as they do not necessarily have the proper infrastructure to supply their population and they also lack a water regulation program. The village of Lupalaya is a small settlement located at approximately -16.195 degrees latitude, -68.841 degrees longitude with an estimated elevation of

of wildfires (Scott and Collinson 1978), as well as charcoal-rich horizons which are evidence of a regular fire cycle (Falcon-Lang, 200; Flacon-Lang and Scott, 2000). The Pre-Quaternary history of fire not only showed the presence of fire in the Devonian and Carboniferous periods, long before the Quaternary period where humans first arrived but it also that this was a global phenomenon with evidence cited from all around the globe. At the global scale,

dy of plant fossils and the understanding the evolution of plant life and ecology of earlier eras is known as paleobotany. Paleobotanists concern with fossil records of plants and their geologic history greatly describes the main concept of paleobotany. Only a small percentage of the plants that ever lived left evidence of existence. The major plant fossils that have been discovered are mineralized wood, flowers in amber, leaf imprints in coal, or other plant life many years ago. Paleobotanists document

The Raton Basin is a structural basin situated in Las Animas and Huerfano counties of southeastern Colorado, and Colfax County of northeastern New Mexico (Speer, 1976). Although millions of years ago the Raton Basin was much different than the present. Colorado and New Mexico were covered by large shallow seas (Murray, 1978). The Basin is bounded on the west by the Sangre de Cristo Mountain range and on the east by two subsurface elements, the Apishapa Arch and the Sierra Grande Uplift. The Apishapa

Introduction The Ekofisk oil field is one of the offshore giant oil field of the north sea with an estimated 6.9 billion barrels of original oil in place. It is located at Block 2/4 in the Norwegian part of the North Sea which is about 300 kilometers southwest of Stavanger. Ekofisk has a few licensed owners namely Total E&P Norge AS (39.90%), ConocoPhillips Skandinavia AS (35.11%), Eni Norge AS (12.39%), Statoil Petroleum AS (7.60%) and Petoro AS (5.00%) with ConocoPhillips Skandinavia AS as the

which species share common ancestors, in particular, how closely related amphibians, mammals and osteichthyes are. The evolution of tetra pods, or four legged animals, from aquatic animals such as fish can be traced back 365 million years ago to the Devonian, 408-360, mya, and evidence shows that this evolution was divergent in nature (Freeman, S. 2011; Myer, A and Zardoya, R. 2004). Divergent evolution, also sometimes termed adaptive radiation, occurs over many geological times and gives rise to a number

As young kids, we spent no shortage of time learning about all of the animals that have inhabited planet earth since the origin of time. And while there are tons and tons of fascinating species in the world, there was always one topic in particular that stood out to all of us- dinosaurs. Whether it was just the sheer concept of another species living on the earth before we were even alive, or the tales we were told about their incredible strength and size, we were transfixed by dinosaurs, specifically

change. Every species in our universe is part of a web. If one specie on the web goes the whole thing slowly starts to fall apart, and when I say species I mean humans included. There were five major extinctions in our world history. The Ordanican, Devonian, Permian, Triassic Jurassic, and the K-t extinction. These five major extinctions were all brought out by different causes, and we are now well on our way into the sixth extinction, and the cause is very clearly, us the humans. We are the cause of

Problem Statement We want to try and develop a material balance equation that tries to give an accurate estimate of the original gas in place in a coalbed methane reservoir considering the absorbed gases, free gases, rock compressibility and certain factors that have strong effect on the original gas in place. Considering so many MBE equations that have been presented by different researchers, we are going to be using raw data from oil fields to with researchers developed material balance equation
