Black Gold and the Nigerian State （1956-2014）： A Critical Review

This article discussed the oil industry in Nigeria and its impact on the economy, environment, and the citizens. The black gold （oil） was first discovered in Nigeria after several trials by white explorers in Oloibiri （present day Bayelsa State） in 1956 by Shell D＇Arcy later renamed Shell-BP. By 1958, Nigeria joined the rank ofoil producers, when its first oil field came on stream. It was in the same year that the first shipment of oil from Nigeria occurred. Since then oil became Nigeria＇s primary export with about 95% of its govemment revenue coming from the ＂black gold＂, pushing agriculture and other sources of revenue to the background. The study discovered that the high revenue realised from the black gold especially after the Civil War, was not used by the government to transform Nigeria from a third world to a first world country as was predicted rather heavily mismanaged. The study further discovered that the multinational companies （MNC） responsible for drilling oil in Nigeria are guilty of polluting and degrading the environment via oil spills, thereby exposing the citizens to all kinds＇ health related problems and further poverty. The study concludes with the following： The corruption going on in the region must be tackled head long so that the citizens （the youth especially） will begin to feel the effect of the wealth generated from black gold. The government should also invest more on the education of its citizens to enable development in the country.

European Explorers＇ Engagements with Sexuality in Indigenous Cultures： The Forsters＇ Interpretations of Tahitian Sexual Practices

While current analyses of European interpretations of non-western cultures are guided by a modern concept of sexuality, this article argues for a more encompassing, historical awareness by drawing historical constructs of sexuality into the analysis. To illustrate the point, it will analyze the accounts of indigenous sexual practices written by the botanist Johann Reinhold Forster and his son Georg, in the wake of Cook＇s voyages. These accounts differ starkly, even though the authors participated in the same expedition. As the post-structural textual analysis of the text makes apparent, each author has a specific concept of sexuality in mind. These perceptions affirm the change taking place in 18th-century European culture, as analyzed by Foucault. Moreover, the textual analysis strongly suggests that their respective views of sexuality impact upon their interpretations of Tahitian culture at large. As a consequence, the article furthers insight into ＂Western＂ ways of interpreting ＂non-western＂ cultures.

Review of research on sonar imaging technology in China

Over the past 20 years,sonar imaging technology particularly for the high-technology sector has been a focus of research,in which many developed countries,especially those with coast lines,have been competing with each other.It has seen a rapid development with increasing widespread applications that has played an important and irreplaceable role in underwater exploration with great prospects for social,economic,scientific,and military benefits.The fundamental techniques underlying sonar imaging,including multi-beamforming,synthetic-aperture and inverse synthetic-aperture sonar,acoustic lensing,and acoustical holography,are described in this paper.This is followed by a comprehensive and systematic review on the advantages and disadvantages of these imaging techniques,applicability conditions,development trends,new ideas,new methods,and improvements in old methods over recent years with an emphasis on the situation in China,along with a bold and constructive prediction to some development characteristics of sonar imaging technology in the near future in China.The perspectives presented in this paper are offered with the idea of providing some degree of guidance and promotion of research on sonar imaging technology.

Analysis of Western Countries' Anti-globalization

Anti-globalization trends are in play in the US and Western Europe where electorates are recalcitrant to allow immigrants into their societies, national sovereignty is sought in certain geographic areas, and the national mood seeks to suppress newly rising countries' trade and development. The continuation of economic downturn in Western countries is reinforced by their internal wealth gap and external competition. As capitalism's demand for profit is now being critiqued along with the emergent profit prospects to be delivered by pending technological progress, the temper of the times could temporarily slow down but not reverse globalization. Timely discussions about reform of international economic order and about an effective national development model should seek sustainable solutions for healthy, stable globalization and development of the world economy.

Accumulation of coal-bed gas in the Wangying-Liujia area of the Fuxin basin

The gas enrichment conditions in the Fuxin basin are compared to those of the Powder River basin.The coal bed depth,the gas content,the individual coal bed layer thickness,and the overall structure thickness of the Powder River basin in the U.S.were examined.The main factors affecting gas enrichment were examined.These factors include the coal-forming environment,the gas sources,the geological structure,the presence of magmatic activity,and the local hydrology.The coal-bed gas enrichment area in the Wangying-Liujia block of the Fuxin basin is then discussed by analogy.A hydrodynamic-force/dike-plugging model based on a magma fractured bed is proposed to explain the gas enrichment in this part of the Fuxin basin.High gas production is predicted in areas having similar conditions.This work will aid future coal-bed gas exploration and development.

Distributive characteristics of reservoirs and exploration potential associated with intrusive rocks of Yingcheng Formation in Yingtai rift depression, NE China

Petroleum geologists have paid great attentions to the volcanic reservoirs of Songliao Basin in NE Chi- na. There are plenty of subvolcanic rocks in the Songliao Basin accompanying the Early Cretaceous Yingeheng Formation. The logging data show the good reservoir potential of these intrusive rocks but the distribution char- acteristics and formation mechanisms of these reservoirs are not clearly understood. Based on the previous stud- ies by using coring, cuts and logging data of Yingtai rift depression, the reservoirs＇ characteristics of intrusive rocks are presented. There are two types of intrusive rocks namely the syenodiorite-porphyrite and diabase which occur as laccolith and/or sill, both having the characteristics of low gamma and high density with little primary porosity and permeability. The prevalent reservoir porosity is the secondary porosity, such as spongy/cavernous pore, tectonic fracture. The laboratory data of porosity of diabase can reach 6.7%, but the permeability is less than 0.6 x 10-3μm2, median pressure is high, indicating that the pore throat of this kind reservoir is small. The maximum logging porosity is about 12%. The change of porosity does not correlate to the buried depth. It is the major significant differences in the distributive characteristics compared to the normal sedimentary rock reservoirs. Most of intrusive rocks underwent alteration diagenesis whilst some were subjected to precipitation diagenesis. The spongy and cavernous pore can be formed during the alteration processes of plagioclase to illite and pyroxene to chlorite. The secondary porosity is greatly correlated with the alteration intensity of matrix, pla- gioclase and pyroxene. There are pyroxenes and more plagioclases in diabase, which cause the higher alteration intensity than the syenodiorite-porphyrites in the same acid fluid. So the porosity of diabase is higher than that of syenodiorite-porphyrites. The top or/and bottom part of intrusive rocks develop the higher porosity. Because those parts are easy to contact formation fluid, and the shrink fractures give the more surface for reaction be- tween fluid and rock. The porosity of intrusive rocks is same to the volcanic rocks in Yingtai rift depression and Xujiaweizi rift depression which bear the prolific gas. It suggests good reservoir potential. Intrusive rocks are hosted by the dark mudstone which indicates semi-deep and deep lake facies belt.

Detection of Hazard Zones over Abandoned Mines of Albania through Geophysical Methods

This study consists to the detection of cavities that could be present over abandoned mines of Albania with the use of SP （self potential） and ERT （electrical resistance tomography）. In general, natural and artificial cavities represent an important investigation target in geotechnical, environmental and scientific studies. These studies could be engineering, archaeological or speleological. For the detection and localization of such cavities during the last 20 years, several geophysical studies have been used worldwide. In this field study, several geophysical methods could be used such as electrical, electromagnetic, gravimetric and seismic ones. Now days, the ground penetrating radar technique and ERT are widely used. Depending on geological formation conditions every used method is more or less effective. As a result of actual conditions of works on ore mines, the dynamic regime of the surroundings areas has undergone changes creating superficial cavities and funnels and as consequence the geological risk to the community is present. The detection of cavities is a challenge for geophysicists and in these cases the ambiguity on interpretation of geophysical data has to be solved properly. The simultaneous application of different geophysical methods and monitoring in time are necessary in order that the field data interpretation could be significant. Geophysical investigations were carried out as tests over galleries of ore mines of Albania. In this study, we present the SP and ERT results in two sites, in Dhrovjan and Perrenjas region. The effectiveness of the used geophysical methods was present.
