This paper sets out to apply a newly developed panel unit root and cointegration approach to the time series of some selected Sub-Saharan African macroeconomic variables as affected by global oil price fluctuations. We consider five countries each from importing and exporting countries in Africa. The cross sections considered were; (exporting countries: Nigeria, Angola, Algeria, Libya, Egypt) importing countries: Ghana, Cameroun, Cote Devoir Rwanda and Benin. The empirical result revealed long run equilibrium relationship among GDP, exchange rate, inflation and balance of payment. The long run normalised equation shows that oil price fluctuation negatively affect GDP and exchange rate, while positively affect inflation though that of inflation is not significant at 5%. Wald test statistics indicates short run causality running from oil price fluctuations to variables under investigation, the lingering effect is more severe in importing nations going by the magnitude of the coefficients of the long run equation, this explain theoretical and practical implication of the major oil price shock on the economy of the importing nations. Hence, we recommend effective utilisation of the excess crude oil benefit during boom especially for exporting nations, secondly, oil producing nations in Africa should take a bold step towards self-sufficient in refined product so as to export the excess to their neighbouring African nations, this will go a long way in ameliorating the major external shock to the African importing nations through cut in cost of transportation and other tariffs from western world

SCIENCE AND TECHNOLOGY IN WORLD LITERATURE: THE GROTESQUE IN MARGARET ATWOOD’S FICTION
Department of General Studies, the Federal Polytechnic, Damaturu.
The present paper aims to examine the presence of the grotesque in Margaret Atwood’s The Year of the Flood. The grotesque would be used in conjunction with the theory of ecocriticism. The ensuing concept – eco grotesque will be used to analyze the novel under three elements of the grotesque: disharmony, abnormality, and the comic and the terrifying. It is significant to highlight the grotesque aspects of Atwood’s fiction so that future readers can see the symbiosis between her ecocriticism and the grotesque mode. Previous studies on her work especially, on The Year of the Flood have not been able to highlight these elements of the grotesque. This study will aim to provide this addition to the body of knowledge on her fiction. In The Year of the Flood the harmony within nature is disrupted. Gene splicing which leads to the creation of new life forms such as the liobam, Pigoon, wolvogs, and the post human crakers results in the reordering of nature. These new life forms are a direct contradiction of the natural order of things. Atwood’s position has been that if the excesses of science and technology is not curbed through ethical regulations; there would be serious catastrophe. The privileging of science over all other forms of endeavor in our world should be urgently reviewed.

The ever increasing demand for digital products with programmability are growing day by day. Digital filters are broadly used in digital signal processing and communication systems in application such as channel noise reduction which is the major setback in the system. In the field of digital signal processing the function of a filter is to remove unwanted part of a signal that is undesirable. In this paper, we present the design of such filter using a novel approach of Fourier series with windowing. The filter performance based on the design specification is tested using filter design and analysis tool (FDAT) of the Matlab. The FDAT is used to define the filter order, response and coefficients. The implementation of the designed filter using Digital Signal Processing (DSP) blockset of the Simulink has shown that the design specification of the transversal Filters were achieved and its performance is at the optimum level.

Business Education Department, Federal College of Education, Zaria
This study investigated the impact of gender, O’level Accounting and attendance on the performance of students in BED 111 examination. Secondary data extracted from the students files and BED 111 result in the Business Education Department, Federal College of Education were used. Multiple Regression Techniques was employed to estimate the nature of the relationship between the variables. The results of the study reveals that gender does not significantly affect the performance of students in BED 111 examination. Furthermore, the study documents positive relationship between O’level Accounting, attendance and academic performance of students in BED 111 examination. The study concludes that O’level and attendance were key drivers of performance of students in BED 111 examination. Therefore, the study recommends that that the management of the college should be organizing orientation for both new and returning students so that the students will be sensitized on the importance of attending lectures. Also, the academic adviser of NCE III should advise students to take option that they have prior knowledge.

Modelling and mold design of a flange tube has been carried out. Proper application of CAD/CAM tools in manufacturing processes minimizes to a greater extent the production cost, lead time and delivers good quality products. CAD/CAM Pro/E software package was used in the creation of the part and the design and assembly of the mold for the created part. Two molds were created due to the complexity of the part to ease its manufacture. These were achieved based on the dimensions and specifications of both the blank and the finished drawings. Finally, NC machining simulation for the wax pattern injection mold cavity was done.

FACILITIES PLANNING FOR SUSTAINABLE DEVELOPMENT OF HUMAN SETTLEMENTS IN THE 21ST CENTURY NIGERIA
Department of Urban and Regional Planning, Kaduna Polytechnic
The paper aims at examining facilities planning as a tool for sustainable development of human settlements in the 21st century Nigeria. The study is the review type. Information was obtained from different sources including international and national journal articles, books, and online search. The content analysis was adopted. The study revealed that in order to make effective proposals for the provision of facilities in human communities, principles of reinforcement, continuity, discontinuity, externalization, concentration and hierarchical association as well as range and threshold standards should be considered in the planing process. It was also revealed that in order to accommodate new growth while improving the quality of city living, there is need to provide adequate community and public facilities. The study also found that major challenges of facilities are in terms of their provision, location, distribution and maintenance. In order to attain sustainable development of human settlements in the 21st Century Nigeria, effective planning of facilities is necessary. It is therefore recommended that the enabling environment be created by all tiers of government for the planning of facilities. It is also recommended that Urban and Regional Planners must ensure that in their development plans compatible facilities are associated while the incompatible ones are disassociated for the attainment of convenience and safety in human settlements. There is also need for town planning agencies to take into account the effects of facilities on the overall urban spatial structure and to ensure that effective development control is enforced for sustainable facilities development

A study of phytoplankton as bioindicators of water quality was carried out for a period of ten months in Thomas Dam between January and October, 2016. Water samples for phytoplankton and physicochemical parameters were collected and analyzed fortnightly between 8:00 – 10:00 am using standard methods. Four sampling sites (A, B, C and D) were chosen on the Dam based on the vegetation pattern and impact of anthropogenic activities. The mean range of physicochemical parameters studied were, water temperature (18.5 – 28.9 °C), pH (7.5 – 8.9), DO (4.8 – 9.1mg/L), BOD (2.2 – 4.9mg/L), turbidity (16.3 – 37.1 NTU), electrical conductivity (131.8 – 335.7µS/cm), TDS (140 – 386.6 mg/L), phosphate (0.15-1.13mg/L) and nitrate (0.14 – 4.78mg/L). Total dissolved solids, electrical conductivity, turbidity and nitrate recorded significant difference between wet and dry season (P<0.05) while no significant difference was observed in DO, BOD, phosphate, temperature and pH. Fourty one (41) phytoplankton species belonging to 33 genera were identified in which Cyanophyta had 20.5%, Chlorophyta (39.9%), Bacillariophyta (31.1%), Euglenophyta (7.9%) and Dinophyta (0.5%). Cholorophyta was the dominant group contributing 39.9% of the total floral composition of 432.org/L. The highest phytoplankton density was recorded at site A with 118.6org/L and the lowest at site D with 99.5org/L. Spirogyra communis had the highest total species count of 10.11% while Ceracium furca recorded 0.04%. With regards to Palmer Pollution Index (P.P.I) 39 was recorded from the 15 phytoplankton pollution indicator genera. Seasonal variation indicated that wet season had 21 P.P.I while 18 scores were recorded during dry season. The presence of pollution indicator phytoplankton species such as Microcystis sp., Oscillatoria sp., Scenedesmus sp., Euglena sp. and Phacus sp. indicates high degree of organic pollution in the Dam. Shannon-Wiener Index, Evenness Index showed high phytoplankton composition and abundance during wet season than the dry season. The results from this study showed that the water body is impacted with various anthropogenic activities from the inhabitants coupled with natural mineralization which facilitate fluctuation of phytoplankton abundance and physicochemical parameters. It is therefore recommended that uncontrolled discharge of agrochemicals around the Dam through irrigation and other human activities should be controlled in order to curtail degradation of the aquatic biota over a period of time.
