Abstract: The origin of boat regattas in Izon land is traced by Henry Bellgam to the advent of the first European traders who arrived in the Niger Delta in the 15th Century. In his article “Boat Regatta” (21) Bellgam asserts that Kings and Chiefs of the Niger Delta travelled in boats either for the purposes of visiting their counterparts in the neighbouring city states or to convey their commodities of trade in boats from one market to the other. The boats carrying these valuables were paddled by men from the kings’ or the chiefs’ households. These treasure boats (Alali-Aru) were provided with security by another boat manned by warriors, the war boat (Omu-Aru). After the abolition of the Trans-Atlantic slave trade in 1807, a new legitimate trade in Palm produces and Palm oil flourished. The Niger Delta Chiefs became the major marketers in this legitimate trade. The markets for the commercial venture were established in the hinterlands where the chiefs who retained their slaves had to travel to sell Palm kernels and oil. This was a highly competitive venture which required able-bodied well fed men to paddle fast to make sure that they arrived early at the markets. The able-bodied men in the chiefs or kings households practiced the paddling movements to synchronize them with traditional drumming, songs and dances in the different war-canoes. Bellgam asserts that it is these creative practices that gradually developed into the aesthetically designed ceremonial events through which sports, entertainment and heritage of the people are showcased.

Abstract: Dance, as one of the performing arts is mostly used for entertainment. In this case, the art form is largely seen as an aesthetic enterprise with little or no utilitarian value. However, some dances, in spite of their being aesthetic are influenced by utilitarian components or movements. This is the situation with the owigiri dance which was initiated as an aesthetic work of art is driven by other traditional dances. These traditional dances such as penge, abo, agene, owu, konkonba, osundu and feletei have cultural annotations and interpretations. The appreciation of the owigiri performance therefore as an aesthetic art, especially at social gatherings should always be done with cultural interpretations of movements and materials used in the dance. This is the legitimate way the owigiri dance can be appreciated wholly as a means of communication.
Effect of Varying Corn Cob and Rice Husk Ashes on Properties of Moulding Sand  [PDF]
Sunday Aribo
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.1015112
Abstract: The use of rice husk and corn cob ashes as aggregates for foundry moulding sand has been studied. 5-12.5 weight percent of rice husk and corn cob ashes were added to the sand mixture and the sand properties determined. A mixture of equal proportion of rice husk and corn cob ashes was also used. In each case, four weight percent water and clay were added to the sand mixture. Some of the properties of the sand tested are: permeability, green compression strength, dry compression strength, green shear strength, dry shear strength, moisture content and permeability. The results showed that the green compression strength, green shear strength, moisture content and permeability decrease with increase in the additives (rice husk ash, corn cob ash, and (50% rice husk and 50% corn cob ashes). While dry compression strength and dry shear strength increase with increase in weight percent of the additives.
Repassivation Behaviour of UNS S32101 and UNS S30403 Stainless Steels after Cathodic Stripping of the Native Passive Film in a CO2-Saturated Oilfield Brine  [PDF]
Sunday Aribo
Advances in Materials Physics and Chemistry (AMPC) , 2015, DOI: 10.4236/ampc.2015.58027
Abstract: Repassivation behaviour of the passive film formed on lean duplex stainless steel UNS S32101 and austenitic stainless steel UNS S30403 in a CO2-saturated oilfield environment has been studied. The native passive film on the alloys was thinned/removed by stepping the potential of the alloy to ﹣850 mV/Ag/AgCl for 30 minutes. Potentiostatic measurements were then taken at potentials of ﹣200, ﹣100, 0, 100 and 200 mV versus Ag/AgCl. Results show that the passive film repassivates at potentials of ﹣200 and ﹣100 mV and 0 mV for both alloys at 50°C. The current density however continues to rise for potentials of 100 and 200 mV. This shows that both alloys are susceptible to pitting at potentials above 100 mV at the test temperature of 50°C.

Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.44A002

The study examined the problem of waste disposal and management in Ughelli. A field survey was undertaken to determine the types, volume, effects and methods of managing solid waste in the Ughelli. The volume of waste was measured at dumpsites in the four existing quarters and from household bins. Appropriate waste characterization methods were employed in classifying the waste into various components on weekly basis. Eighty and twenty questionnaires were administered to households’ heads and industries respectively and summarized with descriptive statistics. The results revealed an increase in the volume of solid waste generated over the years with 15,540 Kg mean annual volume of solid waste generated in Ughelli at dumpsites, and 1104.7 Kg mean volume of solid waste generated per households that never arrives at dumpsites. The composition of solid waste generated and disposed in Ughelli were predominantly food items, bottles/cans and plastics, paper/carton and nylon of sachet water, which were mostly found in market places. The most widely adopted method of waste disposal is open dumping, land filling, dig and bury. It is therefore recommended that government should adopt an appropriate waste collection and disposal agency and also more government approved dumpsites should be established in the area.

National Identity and Crisis of Integration in Multi-Ethnic Nigeria: An Existentialist Perspective  [PDF]

Abstract: One would expect Nigeria after attaining a century old as a nation state on January 2014 to have overcome the problem of national identity and crisis of integration resulting from its multiethnic composition, but recent events have revealed that this desired status is yet to be fully attained. In fact, there have been continuous agitation by various ethnic nationalities ranging from militancy in the Niger Delta south region which has transformed into oil bunkering, armed robbery and organized kidnapping spreading to the southeastern and western part of the country; to various forms of religious fanaticism in the northeastern axis which recently metamorphoses into terrorism and kidnapping as socio-political characteristic of the present Nigeria society, the question that arises is how far Nigeria as a nation state has put itself on the part of achieving national identity and integration of its multiethnic nationalities into a united nation state. Through the methodological approach of historico-logical analysis of identified factors militating against the above objective, this article will proffer the existentialist principle of inter-subjectivity predicated on some tested democratic values such as rule of law, justice, equality, fairness and freedom as panacea for attaining national identity and resolving crisis of integration in Nigeria.
Post-Optimality Analysis of Energy Consumption Model and Utility Application  [PDF]
Sunday A. Reju, Gideon Gope
Open Journal of Applied Sciences (OJAppS) , 2014, DOI: 10.4236/ojapps.2014.414052
Abstract: Problems associated with energy distribution, consumption and management are undoubtedly some of the most significant problems that energy utilities face globally. For instance, when development takes place, the demand for electrical power and in particular domestic electrical energy also increases. Thus improvement of energy distribution policies becomes important for utilities and energy decision making agencies. The authors had earlier [1] [2] provided a mixed strategy 2-player game model for a residential energy consumption profile for winter and summer seasons of the year using a dual-occupancy high-rise (11-storey) building located within the Polytechnic of Namibia, Windhoek. The optimum energy values and the corresponding probabilities obtained from the model extend the usual simple statistical analyses of minimum and maximum energy values and their associated percentages. The time-block and the week-day strategies depict critical probabilistic values worth considering for decision purposes, especially, the necessity and justification for a dual tariff regime for the residential and workplace residents of the building as against the existing institutional uniform energy tariff policy. However, this paper presents extended results of post-optimality analyses for the winter and summer seasons, and thus provides the optimal range of energy values over which the energy consumption can change without changing the optimal tariff estimate parameters obtained from the mixed strategy of critical energy game values. The post-optimality analyses also provide extended information on the mixed strategy of non-optimal week-day solutions obtained from the game model, hence validating one of the essential roles of sensitivity analysis, namely, investigation of sub-optimal solutions. From application point of view, the post-optimality model provides a useful tool for Utilities, especially for identifying flexibility range of optimal break-even energy values for consumers, such as in the informal settlements where metering is rather a challenge to determine varied or non-uniform tariffs.

Abstract: The study assesses the effects of climate change on police operation in Delta state. To achieve this climate, data were extracted from the archives of the Nigerian Meteorological Agency and the Met Station of the Department of Geography Delta State University Abraka, and police operation data were collected from the archive of the police diary at the state police headquarter. The results showed an evidence of climate change in delta state with a rise of 3oC in temperature, and decadal rainfall increase of 120 mm; 56 mm and 121 mm in three epochs (1975-1984, 1985-1994 and 1995-2014). The first and last decades are wetter than the second epoch. There is a general increase in annual Police and vigilant operations from 1975 to 2014 and their operations are significantly dependent on increase in rainfall and rise in temperature. Thus increase in rainfall and rise in temperature bring corresponding reduction in police and local vigilante operations in the state. It therefore recommended that federal and state government should provide rain coat, safety boot, umbrella, good vehicles to police on duty; and police and vigilante should embark on regular patrol be it raining or sunny day. This is because crimes (breaking and entry, armed robbery etc.) increase when it is raining heavily.
