Correlation between manufacturing sectors and foreign direct investment

Abstract : The manufacturing sectors of nation’s economies have without doubt been noted as the chief driver of economic growth the world over. The connection between the Nigerian manufacturing sector and foreign direct investment (FDI) was assessed in this work. The study, in order to empirically examine how the variables are related in the long term and short term, utilised time series data spanning 36 years, while the autoregressive distributed lag (ARDL) and co- integration technique were used. From the result, it is seen that the dependent variables explained R2 of 97% of the variations in manufacturing sector indicators (MFI), while Foreign direct investment, (FDI), Inflation rate (INF), government expenditure (GOE), and money supply (MSP) represent the independent variables. One of the recommendations of the study is that the federal government should consciously increase amount of foreign direct investments (FDI) made available to this all-important sector-manufacturing sector to boost its efficiency especially with respect to percentage impact on GDP and employment generation in Nigeria

Macroeconomic as Basis of Economic Growth : An ARDL Approach

Abstract : We examined the effect of some selected macroeconomic factors reflecting on Nigeria economic growth between the periods of the year 1981 to the year 2015 using Auto Regressive Distributed Lag denoted as ARDL method. Findings revealed that foreign direct investment, and trade openness were the major factors that determine real gross domestic product, especially in the short run. On this basis, this paper, therefore, concluded that increase in the net flow from foreign investors from the rest of the world has a significant effect on the Nigeria economy as it increases the capital inflow and improves economic growth

Data showing the effects of geotechnical properties of lateritic soil mixed with coconut shell powder in Ado-Ekiti, south western Nigeria

Abstract: In this data, the effect of locally available additive Coconut shell powder (CSP) substitute in determining the geotechnical properties of Ado Ekiti soil was assessed. The samples were collected from two borrow pits, Ado-Ijan road and Ado-Ilawe road, at two points each, and were treated using substitute of coconut shell powder, considering several percentages of its content at 0%, 2%, 4%, 6%, 8% and 10%. Laboratory tests such as specific gravity, consistency limit test, grain size distribution test, compaction test, CBR test, triaxial compression test, permeability test was conducted on the soil samples collected, and untreated soil was determined. The summary shows that the liquid limit, plastic limit, Plasticity Index, Maximum Dry Density and Optimum Moisture Content increases with increase in percentage of the additive and later decrease at higher percentage of additive, mostly at 8% and 10% respectively. The value of California Bearing ratio in percentage increases as the percentage of additive increases, although at 0% additive, the soil does not meet specification of road construction and the value of permeability ‘k’ also increases. The summary of triaxial test also shows increase in the strength properties of the soil at certain percentage likewise, the summary of unconfined compressive strength shows same. This indicates that the additives improves..

THE EFFECT OF TILT ANGLE AND MASS FLOW RATE ON THE PERFORMANCE OF A PARABOLIC TROUGH SOLAR CONCENTRATOR VIA EXPERIMENTATION

Solar energy is widely regarded as a very promising alternative energy source due to its potential to satisfy a substantial portion of global energy demand. The efficacy of a solar concentrator is contingent upon operational and weather factors. This paper presents an experimental evaluation of the effect of tilt angle and mass flow rate on the effectiveness of a parabolic trough solar concentrator The parabolic trough solar collector was subjected to experimental testing in LAUTECH's Ogbomoso engineering facility. It has a collector length of 2.1m, an aperture width of 1.2m, an adjustable rim angle of 75o, 90o, and 105o, a focal length of 30 cm, a 10-liter storage reservoir with varying flow rates of  0.0004 m3/s, 0.0008m3/s, and 0.0012m3/s. The temperatures were measured with a 12-channel temperature recorder (SD data logger), while the solar radiation was measured with a solar meter and water was used as a working fluid. Thermal performance analysis was conducted to ascertain the impact of tilt angle, mass flow rate, and weather conditions on the solar concentrator's effectiveness. The results indicate that the system has a greater thermal efficacy with weather elements such as solar intensity and ambient temperature at higher mass flow rates and a 90o tilt angle. This concentrator aids the energy industry by decreasing reliance on electricity and pollution from fossil fuels, thereby minimizing environmental and health issues.

Biopolymer-mediated Green Synthesis of Noble Metal Nanostructures

Polymer-coated noble metal nanoparticles are currently of particular interest to investigators in the fields of nanobiomedicine and fundamental biomaterials. These materials not only exhibit imaging properties in response to stimuli but also efficiently deliver various drugs and therapeutic genes. Even though a large number of polymer-coated noble metal nanoparticles have been fabricated over the past decade, most of these materials still present some challenges emanating from their synthesis. The metal nanoparticles when encapsulated in a polymer and taken up by human cells might show a lower degree of toxicity; however, the degree of toxicity for some of the starting materials and precursors has raised serious concerns. Hence, there is a need to implement the principle of green chemistry in the synthesis of nanomaterials. The use of environmentally benign materials for the synthesis of metal nanoparticles provides numerous benefits ranging from biocompatibility, availability, cost-effectiveness, amenable scale-up to eco-friendliness. The biopolymer-based nanovehicles have been found to be more suitable in the field of nanotechnology owing to their high reproducibility, ease of manufacture, functional modification and safety (they are not carcinogenic). Unlike synthetic polymers where the raw material can be derived from petrochemicals or chemical industrial processes, biopolymers are produced from renewable resources such as plant and/or living organism. They are degradable by natural processes down to elemental entities that can be resorbed in the environment. Furthermore, they can also be modified to serve a particular purpose which explains the myriad of their potential applications. The macromolecular chain of these biopolymers possesses a large number of hydroxyl groups which can easily complex with metal ions. Additionally, these biopolymers also contain supramolecular structures that can lead to new functionalities of their composites with metal and semiconductor nanoparticles. In this chapter, a comprehensive discussion on different biopolymers, green synthesis of noble metal nanostructures, mechanisms, characterization and application in various fields is presented

14 Molar Concentrations of Alkali-Activated Geopolymer Concrete

The increase in construction activities due to economic and population growth has led to the higher demand and utilization of cement. But cement production leads to the pollution of the environment. Consequently, this study examines the utilization of both ground granulated blast furnace slag (GGBFS) and corncob ash (CCA) as source materials in the production of geopolymer concrete (GPC). GGBFS was replaced by CCA in 0%, 20%, 40%, 60%, 80% and 100% respectively using Grade 30 (M30) mix design proportion. Alkaline liquids were prepared to obtain 14 molar concentrations and used to activate the source materials. Slump, density and compressive strength of GPC were determined and compared with Portland cement concrete (PCC). The research findings indicate that GPC has higher compressive strength than PCC. Based on the relationship between the compressive strength and the density, a model equation is established. And the equation is used to predict the compressive strength of GPC with respect to the density. Reprocessing of CCA and GBFS as emerging low-carbon footprints appears to be a feasible solution to the problem of environmental pollutio
