Determination of Heavy Metals and Physicochemical Parameters of Crude Oil Polluted Soil from Ohaji Egbema Local Government in Imo State  [PDF]
Ihenetu Stanley Chukwuemeka, Ihenetu Francis Chukwuebuka, Kalu Georgina Ijeoma
Open Journal of Yangtze Oil and Gas (OJOGas) , 2017, DOI: 10.4236/ojogas.2017.23012
Abstract: The soil physicochemical parameter in Ohaji in Imo State, Nigeria was investigated using Ibeocha, Ekeugba, Awara, Mbirichi and Location as a case study. The result obtained from the soil analysis using standard methods shows that the concentrations of the heavy metals, Pb and Fe were highest in the soil from Ibeocha (0.045 ppm) and Mbirichi (0.126 ppm) which show high rate of industrial activity and oil spill in those areas. There was no remarkable change in pH, but temperature followed the pattern of heavy metal concentration with acidic (lowest) values at the centre. The cation exchange capacity of the soil sample from location (14.066 ppm) shows that this soil sample has a lower contamination to compare to other soil samples from other location. Containment of the effects should be encouraged as soil from these sampling locations is contaminated due to oil spill.
Quality Assessment of Common Instant Noodles Sold in Nigeria Markets  [PDF]
Chukwuebuka T. Onyema, Uche E. Ekpunobi, Augustina A. Edowube, Stanley Odinma, Chinweotito E. Sokwaibe
American Journal of Analytical Chemistry (AJAC) , 2014, DOI: 10.4236/ajac.2014.517124
Abstract: Proximate and heavy metal analysis of five instant noodles samples was carried out using standard analytical methods. The proximate analysis showed the presence of moisture content (3.65% - 7.80%), ash content (1.11% - 5.50%), fat content (13.64% - 18.69%), crude protein content (0.167% - 0.202%), crude fibre content (1.00% - 9.25%) and carbohydrate content (63.68% - 79.72%). All essential elements (Fe and Zn) investigated in the noodle samples occurred within the threshold limit of WHO, (2003) standard (10.00 - 50.00 mg/kg and 5.000 - 22.000 mg/kg) while the heavy metals (Cd, Cr, Mn, Ni and Pd) in some samples occurred at levels relatively above the minimum tolerable limit of WHO, (2003). Hence, caution should be taken in the successive consumption of these noodles to avoid diseases associated with the over time accumulation of these heavy metals especially in samples where they appeared in relatively high amount.
Biochemical Manifestation of HIV Lipodystrophy Syndrome
Kenneth Ihenetu, PhD,Darius Mason, PharmD
International Journal of MCH and AIDS , 2012,
Abstract: Objectives:Highly active anti-retroviral therapy (HAART), including protease inhibitors (PI) have led to dramatic improvements in the quality and quantity of life in patients with acquired immunodeficiency syndrome (AIDS). However, a significant number of AIDS patients on HAART develop characteristic changes in body fat redistribution referred to as lipodystrophy syndrome (LDS). Features of LDS include hypertrophy in the neck fat pad (buffalo hump), increased fat in the abdominal region (protease paunch), gynecomastia and loss of fat in the mid-face and extremities.Methods:The aim of this paper is to review the current knowledge regarding this syndrome. This article reviews the published investigations on biochemical manifestation of HIV lipodystrophy syndrome.Results:It is estimated that approximately 64% of patients treated with PI will experience this syndrome. Biochemically, these patients have increased triglycerides (Trig), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C) and extremely low high-density lipoprotein-cholesterol (HDL-C).Conclusions and Public Health Implications:It is hoped that awareness of this syndrome would aid in early diagnosis and better patient management, possibly leading to a lower incidence of cardiovascular complications among these patients.
Effect of Asian Dust Storms on the Ambient SO2 Concentration over North-East India: A Case Study  [PDF]

Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.26090
Abstract: Ambient SO2 concentration at a high rain fall site, Shillong (25.67oN, 91.91oE, 1064 m ASL), located in North-East India, was measured during March 2009 and January 2010 with the aim to understand the effect of long range transport of pollutants from North-East Asia on the ambient SO2 levels at this relatively clean site. The concentrations recorded during the former sampling period were very high (Max: 262.3 ppb)—which decayed down gradually towards the end the sampling period—whereas those during the latter sampling period were well within the acceptable limits (Max: 29.7 ppb). This elevated SO2 concentrations during March 2009 is proposed to have association with a major cold air outbreak and an associated cyclone preceding one of the dust storm events reported in China, and a resultant sudden change in wind trajectory leading to the long range transport of pollutants to the sampling site. The argument is formulated on the basis of the back trajectory analysis performed using HYSPLIT for the month of March 2009—the plots clearly showed a drastic change in wind trajectories between 8th and 15th of March 2009 wherein the winds traveled over some of the highly polluted regions such as the Perm region of Russia—and on the results from model runs performed using the global 3-D model of tropospheric chemistry, GEOS-Chem (v8-03-01)—it clearly showed the tropospheric SO2 over Perm region in Russia peaking during Nov, Dec, Jan, Feb and Mar every year, possibly due to central heating. The observation of long range transport of SO2 from the highly industrialized areas of Perm in Russia to North-East India during dust storm events has important implications to the present understanding on its relative contribution to the Asian pollutant outflow to the Pacific during spring as the GEOS-Chem model runs also showed regions in and around Russia with relatively high concentrations of atmospheric NOx, Peroxyacetyl Nitrate, Lumped Peroxypropionyl Nitrate, HNO3, HNO4,C3H8, C2H6, SO4, NH4, Inorganic Sulphur Nitrates and Lumped Alkyl Nitrate.
Temporal Trends in Ambient SO2 at a High Altitude Site in Semi-Arid Western India: Observations versus Chemical Transport Modeling  [PDF]
Timmy Francis
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.37079
Abstract: Ambient sulphur dioxide (SO2) measurements have been performed at a high altitude site in the semi arid region of western India, Gurushikhar, Mt. Abu (24.6°N, 72.7°E, 1680 m ASL), during different sampling periods span over Sep-Dec 2009 and Feb-Mar 2010. A global three dimensional chemical transport Model, GEOS-Chem, (v8-03-01) is employed to generate the SO2 profile for the entire region for the different sampling months which in turn is used to explain the major features in the measured SO2 spectra via correlating with HYSPLIT generated wind back trajectories. The mean SO2 concentrations recorded at the sampling site varied for the different sampling periods (4.3 ppbv in Sep-Oct 2009, 3.4 ppbv in Nov 2009, 3.5 ppbv in Dec 2009, 7.7 ppbv in Feb 2010 and 9.2 ppbv in Mar 2010) which were found to be strongly influenced by long range transport from a source region surrounding 30°N, 75°E—the one projected with the highest SO2 concentration in the GEOS-Chem generated profiles for the region—lying only a few co-ordinates away. A diurnal cycle of SO2 concentration exists throughout the sampling periods, with the greatest day-night changes observed during Feb and Mar 2010, barely detectable during Sep-Oct 2009, and intermediate values for Nov and Dec 2009 which are systematically studied using the time series PBL height and OH radical values from the GEOS-Chem model. During the sampling period in Nov 2009, a plume transport to the sampling site also was detected when a major fire erupted at an oil depot in Jaipur (26.92°N, 75.82°E), located few co-ordinates away. Separate runs of the model, performed to study the long range transport effects, show a drop in the SO2 levels over the sampling region in the absence of transport, throughout the year with Jan to Apr seen to be influenced the lowest by long range transport while Jul and Dec influenced the highest.
Personal Identity and “Life-Here-After Poetics”: A Critique of Maduabuchi Dukor’s Metaphysics  [PDF]
Francis Offor
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31A024
Abstract:

This essay examines Maduabuchi Dukor’s perspective on the African conception of man, personal identity and“life-here-after”. This is with a view to showing that although, Dukor’s views represent what obtain among some ethnic nationalities in Africa, this nevertheless does not provide a basis for generalising across the whole of Africa, as there are countless number of ethnic groups in Africa to which Dukor’s general claims may not be applicable. Given the varieties of metaphysical conceptions of man and destiny in Africa which we are yet to fully explore, and given also the inherent contradictions in some of these conceptions, which calls into questioning, the veracity of claims made therein, it will amount to a major logical error to make sweeping generalisations that would be representative of the whole of Africa. Such generalisations would remain a non-holistic, but partial representation of the African conception of man and human destiny.

For a Holistic View of Biotechnology in West and Central Africa: What Can Integrated Development Approaches Contribute?  [PDF]
Francis Rosillon
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.49112
Abstract:

Africa, ever on the lookout for development levers that will allow its economy to take off, is turning more and more towards technology. This is one of the possible modern avenues to success, especially the use of the biotechnologies that are so touted by Western countries. However, the hope placed in these new technologies must not hide the long-proven fact that technology alone is not enough to solve development problems. Biotechnologies do not escape this rule. Biotechnologies can be the best and the worst things for the people of Africa. Beyond their technical contributions, we must be wary of their boomerang effects and collateral damage. A country’s development is actually more complex than simply implementing technology, and in the current global environmental context a holistic vision is necessary to ensure sustainable development. In the area of water, this integrated vision emerged on the international scene during the Dublin Conference in 1992, which consecrated the principles of Integrated Water Resources Management (IWRM). More recently, the Eco-Health concept strives to combine human health and ecosystem health while incorporating a socioeconomic dimension into the health and environmental spheres. The concern to mesh human activities better with environmental protection was materialized previously, in the 1970s already, through impact studies. After presenting this set of tools in the service of a holistic approach to the environment and development, we shall see that these approaches can inspire the players when it comes to the ways they implement biotechnologies. At the end of the day, a holistic approach to biotechnologies in Africa will be facilitated by enhanced information and communication and reliance on peasant farmers’ expertise. It will have to be rooted in broader participation of the players concerned. This integration will also concern environmental and land-owning aspects, without forgetting socio-cultural acceptance of the projects and the links with health. Ultimately, it will also mean putting the human at the heart of development by taking all the richness and particularities of African society into account.

Udo Etuk on the “God of Africa”: A Response  [PDF]
Francis Etim
Open Journal of Philosophy (OJPP) , 2018, DOI: 10.4236/ojpp.2018.85041
Abstract: Some scholars like Rabbi Ini Mbebeng, Rabbi Ettah Essien and Prof Udo Etuk have argued against Ibibio nay Africans having the idea of Supreme Being identical with that of the West given their polytheistic conception of God with attendant pan-theistic proclivities. On the other hand, scholars like Idowu regard such position as anachronistic and retrogressive since African has what he calls, “diffused monotheistic” idea of God which in description and analysis is similar to that of Western typology. This article as a contribution to that debate examines Abasi as a name of the God among the Ibibio from philo-ontos-linguistic perspectives and comes to the conclusion that not only is it true that the Ibibio nay Africans in general have a superlative idea of God but that the African idea of God is more humanistic and existentially relevant than that of the West thus solving the attendant difficulties of explaining the relationship between God and the world and the issue of the problem of evil which resulted in such idea as Dues abscunditus in Western conception of God.
Metaphysics of Terrorism  [PDF]
Francis Etim
Advances in Applied Sociology (AASoci) , 2018, DOI: 10.4236/aasoci.2018.811041
Abstract: Terrorism as the calculated use of violence or the threat to violence through the employment of intimidation and violence in order to attain goals that are political, religious or ideological in nature has taken a global dimension and at alarming frequency such that any curious mind cannot afford to over look. Its persistence despite global condemnation and effort at curbing it naturally evokes curiosity regarding its root cause(s). Scholars have tried to dig out its root causes ranging from poverty, lack of education, religious fanaticism, psychological malady and political reasons and so on. Solutions however differ based on its perceived causes. The question is why terrorism has continued unabated. This paper believes that since human actions are elicited by the idea of the good then terrorism as a human act is based on a disoriented perception of the good. This disoriented perception is premised on a more primordial cause, an ontological lacuna that can be tagged a “search for meaning” which the terrorist tries to fill by his terroristic act. This gives the terrorist a sense of fulfilment and relevance. The panacea, the paper submits, is in a metaphysical deconstruction and construction of the terrorist mind-set based on an ontology called affective humanism.
Ontology of African Ritual  [PDF]
Francis Etim
Advances in Applied Sociology (AASoci) , 2019, DOI: 10.4236/aasoci.2019.91001
Abstract: African rituals, like other phenomena of African cultural heritage are usually faced with criticisms of being either superstitious, fetish, mundane or simply irrational. These criticisms, often based on certain logical criteria, have categorized the African mode of thinking as illogical, unreasonable and non-rational. Given the proclivity of the African mode of thinking of fusing the epistemological into the metaphysical, such criticism could either be excused or be regarded as a misinterpretation, misrepresentation and non-sequitur. However, the issue at stake calls for a deep examination of some of these phenomena to establish their reasonableness as veritable reality among Africans with serious existential import. One of such phenomena is ritual, which is actually pervasive as far as African existential reality is concerned. This paper examines African ritual to establish its reasonableness by establishing its ontology. The paper argues that based on African ontology, African rituals cannot be judged on the principles of Western scientific rationality but rather should be seen as a non-rational action like other human phenomenon like love or possessing rationality internal to the metaphysical beliefs that underpin the African worldview.
