Comparative Study of Physico-chemical Characteristics of Some On-farm Research Ponds, Ethiopia

Author(s): G. GOSHU AND O. C. AKOMA (2010)
Changes in nutrient composition of four on farm research fish ponds measuring 100m in area and 1.5m depth and located on the North Eastern range of the Ethiopian highlands were studied in the wet season of 2008. The ponds stocked with Oreochromis niloticus were categorized according to their sources of water; subsurface and surface waters and the study was aimed at investigating differences in physico-chemical characteristics and nutrient composition of the ponds. Results showed that conductivity, total hardness, nitrate and ammonium were remarkably high in the subsurface water sourced ponds while temperature, turbidity, chloride, dissolved oxygen concentration and nitrite were high in the surface water sourced ponds. Higher turbidity in the ponds with water replenishment from surface water did not result in higher ionic concentrations and highly significant correlation between two nitrogen species (nitrate and ammonium) and dissolved oxygen in subsurface water ponds reinforced the overriding effect of management practices adopted by the farmers (which may include use of organic fertilizers and animal dung) rather than water source related factors in influencing the nutrient composition and material budget of the pond.

Comparison of Heavy Metals Levels in Wholefish Samples of Mud Fishes. *researcher, Vol. 3 (10): 7-12 (issn: 1553-9865)

Author(s): ERHABOR, C. U.; OBASOHAN, E. E. AND EGUAVOEN, I. O. (2011)
Two mud fishes common in the stream are Clarias gariepinus and Parachanna obscura. The concentration of Lead (Pb) Zinc (Zn), Nickel (Ni), Iron (Fe) Manganese (Mn) and Copper (Cu) in the whole fish samples of the two mud fishes - Clarias gerapinus and Parachanna obscura from Ibiekuma Stream Ekpoma, Nigeria were studied. The fish samples were collected from the three stations on the stream using variety of fishing gear. The samples were stored, identified, digested and analyzed by atomic absorption spectrometry 969 solar unicam. The whole fish mean concentration in mg/kg for Clarias gariepinus ranged from 228.75 ± 0.1 - 268.00 ± 0.20 (Fe), 5.18 ± 0.02 - 8.40 (Cu), 15.13 ± 0.04 - 19.03 ± 0.03 (Mn) and 18.15 ±0.03 - 21. 68 ± 0.04 (Fe), 6.10 ± 0.10 - 11.64 ± 0.04 (Cr), 26.80 ± 0.08 - 38.40 ± 0.03 (Mn) and 34.40 ± 0.05 - 39.40 ± 0.02 (Zn) . the results showed that both fishes bioaccumulated higher heavy metals (except Ni and Pb) to varying levels. Results also showed that Parachanna obscura bioaccumulated higher heavy metals more than Clarias gariepinus. The different mean concentrations might be as a result of different ecological needs, metabolic, feeding pattern and different sizes of fishes. Metal concentration also varied from station to station. Some heavy metal concentrations in both fishes in the stream exceeded WHO recommended levels in food fish. Therefore, consumption of fishes from Ibiekuma Stream could induce metal health hazard in man.

Published at :La Rivista Ital Delle Sostanze Grasse
Composition of cohune (Attalea cohune) kernel and kernel oil Abstract The kernel composition, fatty acid composition, and fatty acid distribution on triglycerides of kernel oil from Attalea cohune palms grown in Nigeria have been studied. Lauric was the major fatty acid in whole oil and was also the dominant fatty acid in the triglycerides and in the 2-monoglycerides derived from them by pancreatic lipase hydrolysis. All the fatty acids present exhibited a preferential esterification at the 1,3- positions of triglycerides except for lauric which showed a preference for the 2-position, and myristic which exhibited a near random distribution. Proximate analysis of Attalea cohune kernel gave moisture 2.8%, crude protein 1.5%, oil 65.8%, crude fibre 3.3%, ash 1.5% and nitrogen free extract 25.1%.

Published at :Pakistan Journal of Scientific and Industrial Research
Abstract Analytical characteristics, fatty acid composition and cooling characteristics of tucum fat, its fractions from acetone crystallization, and pindó fat have been determined. These characteristics have been compared with those of the palm kernel and coconut stearins. Fractionation of tucum fat (slip point 32.0 deg. C) gave two fractionation; a higher melting fraction (yield 36.7%, slip point 34.0 deg. C). Tucum fat and its fractions had slip points, saponification values and iodine values similar to those of palm kernel stearins, while pindó fat had a lower slip point and saponification value. Tucum fat fractions had faster solidification than whole tucum fat, pindó fat, palm kernel stearin and coconut stearin. Cooling characteristics of tucum kernel fat, its fractions, and pindó fat were similar to those of palm kernel stearin. Tucum fat and pindó fat had fatty acid composition similar to that of palm stearin. Relative to the whole fat, tucum fractions had less lauric acid; the first fraction contained more myristic, while the unsaturated fatty acids oleic and linoleic acids were enhanced in the second fraction. Key words: Astrocaryum vulgare, Arecastrum romanozoffianum fat. Pakistan J. Sci. Ind. Res. 31: 811 – 814.

Contributions of Nigeria’s Three Main Religions to the Concept of Religious Tolerance in Contemporary Nigeria” in Epha

The author reviews the religious situation in Nigeria, blessed by African Traditional Religion, Christianity and Islam which migrated from the Middle East and blames the religious intolerance in Nigeria on the two foreign religions. He argues that these religions are inherently intolerant because they are monotheistic and prophetic religions whose God is jealous and whose prophets demand obedience. He proposes that the tolerant attitude of polytheistic religions, as evident in African traditional religion, which tend to accommodate should be emulated by the adherents of the monotheistic religions.

Corporate Time Utilization Among Nigerian Workers: Some Empirical Evidence

Published at :ASCON Journal of Management, 4(2), 12-19
The problem of time utilization among Nigerian Workers has been the subject of theoretical discussions for some time now. In this study a number of emerging hypotheses concerning the utilization of corporate time were tested using eighty junior employees selected from twelve large public and private sector organizations located in Benin City, Ibadan and Lagos. Participant observation and questionnaires were used as data gathering instruments. The results showed that the amount of time worked by employees was significantly less than that paid for by management and that workers in the private sector actually worked more hours. The workers wasted an average 50.6 percent of each work day. However, the marital status, age, and sex of the workers did not affect their time utilization.

Corruption, Anti Corruption and the Judiciary in Nigeria

Author(s): OBOKHAI L. OBADAN (2014)
Published at :Igbinedion University Journal of Jurisprudence & International Law, Vol. 1
Despite the National and International Condemnation of Corruption as a social vice in most societies and its seeming embedding in Nigeria’s business cultures, most Nigerians like passing the gauntlet left from politicians to administrators, business men and some professionals. This paper centrally 'seeks to demystify the myth of incurability ascribed to this phenomenon. The Paper begins by exploring the meaning of constitutions in relations governance and within the circumference of democratic States. We further consider various conceptual and theoretical meaning of corruption. The paper place tremendously analyses on Anti-corruption methodology and the Legal system approach to curbing corruption it thereafter scrutinizes the Legal framework for combating Corruption and the Judiciary: This work finally poses and resolves the all-important question whether the judiciary that is a product of this society deserve the derogatory accolade of a cross bearer of corruption? We conclude that institutional Corruption is a hydra headed phenomenon and cannot be eradicated with a singular approach. With the initiatives put in place to complement the existing laws, one should have thought our fight against corruption will be easy. What seems indispensable is the lack of political will to deal with corruption. Most of the handicap suffered by the judiciary in the full utilization of the anti¬corruption laws stem from the fact that the Executive arm of government controls the judiciary via the Attorney-General and indirectly the judiciary does not often want one of its own to be exposed.

Counselling Techniques for Managing Adolescents with Personality Disorders.

Author(s): ODUH, W. A. (2013)
Published at :Edo Journal of Counselling
This article attempted to analyse the various personality disorders discernible among adolescents in the Nigerian school system. The school system is a community of individuals, both adults and adolescents, who are expected to interact and maintain good interpersonal relationship. If not properly managed, the presence of clients with personality disorders could disrupt the harmony expected in the school environment. Personality disorders are conceptualised as enduring patterns of maladaptive behaviour exhibited at different social milieu by individuals. Such behaviour could interfere or inhibit the functional capabilities of the sufferer or cause distress to others. Etiologically, the emergence of these personality disorders could be traced to childhood and subsist throughout adulthood. The study also observed that personality disorders are not genetically located. Rather, they are environmentally induced abnormalities and could permeate all dimensions of human development. The work highlighted different counselling strategies, skills and approaches that could be applied in assisting clients with such disorders to adjust to the school environment.

Author(s): AGBOOLA, JAMES. O. & ABIKWI M. I. (2014)
Published at : EDO JOURNAL OF COUNSELLING 2014. An Official Publication of Edo State Chapter of Counselling Association of Nigeria
Abstract Youth unemployment has become a great cankerworm that has eaten deep into the fabrics of our society. It has led so many youths into involving themselves in so many anti-socio vices like kidnapping, rape, robbery, internet and local frauds, militancy and other social delinquent behaviours. Youth unemployment is divesting to the individual psychologically and to the society economically. This paper therefore examined creation of employment for youths using effective career guidance and entrepreneurship education as potential interventions. Five recommendations are made and these include: making Career guidance services compulsory and available for students at all levels of education to help them make realistic career choices; Government should ensure that financial institutions grant soft loans to potential and prospective youth entrepreneurs in order to encourage small scale businesses; Incorporation of entrepreneurship education into the curricula from middle basic education classes through secondary schools and tertiary institutions; Government should concentrate on those activities where youths are known to have comparative advantage and Programmes that are meant for skills acquisition for youths should be properly carried out with wide publicity and serious supervision to ensure that those who the programmes are meant for benefit from it.

Author(s): F.O.J. OBOH (2004)
Published at :Benin Science Digest
Abstract Palm oil samples collected from various markets and mills in Edo and Delta states of Nigeria were subjected to chemical analysis. Some of these values were in excess and are indicative of poor oil quality. Inadequate harvesting schedules, over ripening and long storage periods are contributory factors in the poor quality of palm oil. Iodine values ranged from 54.2-57.1, saponification values from 200.8- 205.0 and free fatty acids from3.8-17.3%. Peroxide values ranged from 0.8-4.8 meq/kg, while carbonyls measured from 0-0.68 mg/g. Monoacylglycerols, ?-carotene and total tocopherols were found in the following concentrations: 0.33-0.86%, 110.0-210.0mg% and 1.0-1.7mg/g respectively. Copper ranged from 0.13 -0.88 ppm, while iron measured from 5.0 – 40.0 ppm. The fatty acids found were typical of palm oil samples and included lauric (0.3-3.4%), myristic (0.5-1.4%), palmitic (41.1-52.0%), stearic (3.9 5.1%), oleic (32.6-43.8%) and linoleic (6.7-9.4%).

Cybercrime and Its Impact on the Youth

Author(s): OSAGIE, S. U. M. AND OBAHIANGBON K.O. (2014)
Abstract The internet offers numerous advantages in today’s changing world. Most glaring is the transactions (Local or International) embarked on by people on a daily basis. Knowing that internet is a collection of segmented (local) networks linked together by a common purpose for sharing resources or information and being a borderless society crime easily spreads from one country to another leaving the end users at risk. Most cumbersome is the lack of legal standard to combat this illicit act due to diversity in traditions, culture and religious beliefs of end users. It is therefore paramount to have idea of what happens online during such transactions, especially with respect to insecurity (Cybercrime) and the impact on the Youth. This research is aimed at looking into the impact of cybercrime on the youth and the measures employed in avoiding crime when surfing. A survey was conducted in Benin City, Nigeria, using a questionnaire to obtain a valid result on its awareness and 97.1% of the sampling data revealed that there were no legal actions taken in combating and restoring hope to the youth who have their data invaded by intruders/crackers.

Decentralization of Education in Nigeria: a Panacea for Functional Education and National Development

This paper examined the decentralization of education in Nigeria as a panacea for functional education and national development. Concentration of power at the federal level as currently existed is not the best to achieve much needed rapid functional education for values, knowledge, skills and national development. Decentralization of power from the federal government to state and local governments is the way to go, especially in the management of our education system. Education can be best delivered at the state and local government levels. Decentralization of educational management in Nigeria will encourage creativity and innovation in our primary and secondary schools, and universities. It will enhance the availability, adequacy and functionality of schools physical facilities, and promote efficient method of managing schools and spur rapid national development. It was concluded that decentralization of school management is a panacea for functional education and national development. The paper recommended that education in Nigeria should be pursued at the state and local government levels to enhance standard and reduces official corruption in school management.

Deploying Banking Principle of Money Had and Received to Fighting Corruption in Nigeria

Author(s): OBOKHAI L. OBADAN (2012)
Published at :Igbinedion University Journal of Jurisprudence & Public Law Vol. 2
The issue of corruption in the world has assumed a proportion that has attracted global frontal attack and condemnation, Presidents of Countries and highly placed individuals in the developed world have been known to be prosecuted and severe sanctions given. In the developing nations like Nigeria, efforts are also been made to fight corruption which has been the bane of leaders and have slowed down developments. Various institutions and laws have been put in place but none seem to be working as corrupt officials get away with their loot by such novel issues as plea bargaining. But none of our laws seem to be questioning the source of wealth not genuinely worked for but earned and make proper restitution to the nation except the National Drug Law Enforcement Act1 that makes culprit forfeit their loot, hence this paper’s call for the deployment of this subject matter to arrest the high level of corruption unearthed in Nigerian’s Oil and Gas sector and high cost of governance in the wake of the Oil subsidy crises.

Determination of Post-dredging Concentrations of Selected Trace Metals in Water, Sediment and the Freshwater Mudfish (clarias Gariepinus) from Ikpoba River, in Benin City, Nigeria. *african Journal of Biotechnology, Vol. 6 (4): 470-474

Author(s): OBASOHAN, E. E. AND ORONSAYE, J. A. O. AND EGUAVOEN , O. I. (2007)
This investigation monitored the post-dredging concentrations of Cu, Mn, Zn, Cr Ni and Pb in the water, sediment and the freshwater mudfish; Clarias gariepinus from Ikpoba River in Benin City, Nigeria, over a six-month (February -July, 2005) period. The results showed that the levels of Mn, Ni and Pb in water and Cu, Mn, Cr and Pb in fish were higher than the recommended levels in drinking water anf food fish and could pose health hazards. The result also showed that the post-dredging metal contamination levels in water and sediment of the river were lower than available pre-dredging levels, but in fish the differences between the post-dredging and pre-dredging levels were not significant and suggested that the dredging could reduce metal contamination levels in the river. Consequently, continued dredging of the river is recommended as it has the potential to substantially improve the quality of the water and reduce hazards posed by heavy metals to the livestock and human population that depend on the river for drinking and other uses.

Determination of Selected Heavy Metals in a Freshwater Fish (erpetoichthys Calabaricus) from Ogba River, Benin City, Nigeria. Tech Journal, Vol. 1:170-178

Author(s): OBASOHAN, E. E.; O. I. EGUAVOEN AND J. A. O. ORONSAYE (2005)
A study to assess and monitor the concentrations of copper, zinc, cadmium, nickel and lead in water of Ogba River was carried out from November 2003 to October 2004. The same metals were also determined in wholefish samples of fish (Erpetoichthys calabaricus) from the river. The results showed higher concentrations of all metals in fish than in water and indicated bioaccumulation in fish. The distribution of the metals (except Zn) in both fish and water in the river followed the same pattern. Cu and Zn were the most bioaccumulated metals, while Cd and Ni were the least bioaccumulated. The concentrations of the metals in water were below WHO and FEPA allowable limits and suggested that the water of the river is suitable for drinking, but the concentrations of Cu and Ni in fish exceeded the maximum allowable limits in food fish. Consequently, close monitoring of metal pollution in OGBA River is strongly recommended in order to adequately advise on the consumption of the fish of the river.

Development of a Semi-automated Electoral System Case Study: Nigeria Electoral System

Published at :electronic Journal of Computer Science and Information Technology (eJCSIT), Vol. 4, No. 1, 2012
In developing democracies of the world, the electoral process is often enmeshed in distrust, fraud, unprecedented level of rigging and in most cases ends up in courts of law where millions of hard earned funds (public and private) are wasted. Nigeria, despite her democratic experience, has remained ‘exemplary’ in such profligacy. The reason has always been the absence of a reliable electoral process capable of ensuring a fraud-free general election with the use of the available technology. In this paper, a Semi-Automated Electoral System (SAES) that uses biometric technology is proposed to enhance the electoral system and minimize fraud often associated with the process. The system is based on research into the past electoral processes in the years 2003, 2007 and 2011 in Nigeria and the attempted but unsuccessful introduction of said technology. Biometric technology is the most patronized identity enhancement technique used today in the ICT industry and has been successfully implemented where the identity of a user, customer, citizen, traveler, student etc. is of prime importance. For the development of the proposed system, the fingerprint biometric technology was used because of its reliability, correctness and accessibility. In the proposed system, the electoral process is categorized into three sub-processes viz; the constitution, validation of the voter register and the elections proper. sed because of its reliability, correctness and accessibility.

Development of Tucum Pulp Oil Fractions for Possible Edible and Industrial Use

Author(s): OBOH, F.O.J. & ODERINDE, R. A. (1988)
Published at :La Rivista Italiana Delle Sostanze Grasse
Development of tucum pulp oil fractions for possible edible and industrial use. Abstract Tucum (Astrocaryum vulgare Mart) pulp oil has been fractionated by an acetone crystallization procedure to yield a solid fat (stearin) and a free flowing oil (olein). Yield of solid fat was 14.3% and that of oil was 85.7%. As in whole tucum oil, the major fatty acids in fractions were palmitic and oleic, with smaller amounts of stearic linoleic and arachidic acids. Fractionation led to a randomization of palmitic acid and oleic acid in olein and stearin triglycerides. Relative to whole tucum oil, there was an enhancement of the high melting triglycerides S3 and S2O and a lowering of SO2 in the stearin fraction, while in the olein there was a lowering of S3 and S2O and an enhancement of SO2.
