Facility Layout using Computer Routing: A Review
Get PDFFacility Layout is an essential aspect of any industry or firm because it determines how well
the industry would operate when production begins and how productive its processes would
be. Some of its objectives are to save cost, and time, improve productivity and enhance
customer satisfaction. Facility layout design is also fundamental because it lays the
foundation for how the layout would look before it is produced physically or further improved
on. The review discusses how CORELAP is being implemented and its firms or industries'
effects where it was implemented. From this review, it can be concluded that CORELAP is
an efficient and effective technique that can be used to create new layouts and redesign
existing layouts to reduce material handling distance, save time, and save costs incurred
Investigating the effect of salt concentration on oil recovery during guar gum polymer flooding: A simulation study
Get PDFReservoirs producing heavy crude oil (gravities <20) pose serious production challenges due to oil’s highly
viscous nature. The risks of optimizing oil production from these reserves to meet energy demands are more
feasible than the financial requirements of venturing into newer fields. Water injection options in such reservoirs
substantially affect the oil produced but are limited, especially when the reservoir fluid is more viscous than the
injected water. Thermal options for heavy oil reservoirs are often discouraged due to loss of energy and the
lighter portion of the hydrocarbon fluids, hence less expensive and environmentally friendlier options such as
polymer flooding are encouraged. This study considers polymer injection options and the effects of salt concentrations
as it affects heavy oil recovery us. Firstly, 6 wt %’s of Guar Gum (GG) (0.1, 0.2, 0.3, 0.4, 0.5, and 1.0)
are diluted in 300 ml of water and the rheological properties estimated from these concentrations are used to
build 6 different reservoir models (with an oil density of 20lb/ft3) in conjunction with polymer/salt keywords,
rock and fluid properties using the Eclipse black oil model. Two salt concentrations are considered individually
for each polymer concentration and a base case of natural production is considered. An oil recovery of 5.90 %
(primary production), 30.78 % (water injection), 48.53 %, 48.74 %, 48.78 %, 49.18 %, 49.34 %, and 55.49 % are
recorded under polymer flooding. An oil recovery of 55.04 % and 54.60 % is recorded at 5 % wt. and 10 % wt.
Salt concentrations during 1 % wt. Polymer flooding. Increasing GG concentration will evidently increase oil
recovery due to a higher viscosity index while increasing salt concentrations will reduce oil recoveries

EVALUATION OF THE ENVIRONMENTAL IMPACT OF ENERGY SOURCES FOR A THERMAL POWER PLANT
Get PDFConserving the dwindling energy sources and preserving the environment are pertinent twain
sustainable development issues in climes where renewable energy techniques have not matured. While
the use of viable alternative sources of fuels has been identified as being able to minimize the
occurrences of power outages caused by short supply and non‐availability of the primary fuel for
generating electricity in the thermal power plants, the use of operating conditions which are favorable
from both thermodynamic and environmental viewpoints is equally essential for the preservation of
energy sources and the environment. In this work, air‐fuel parametric studies on low‐pour fuel oil (LPFO)
as an alternative to natural gas in electricity generation were conducted based on environmental
impacts. Typical emissions from a boiler designed to fire both fuels were simulated with HYSYS 8.8. The
potential environmental impacts (global warming, eutrophication, acidification, air smog, and human
health particulate) were simulated using GaBi. The outcomes of the studies show that an air‐fuel ratio of
16.1 previously prescribed in earlier work from a thermodynamic viewpoint was not favorable to all the
environmental indicators considered. A more informed decision on the choice of air‐fuel ratio for fuel
combustion can be achieved by developing a robust and encompassing pollution tax
Linguistic Inference in Leadership
Get PDFLanguage, a communication tool in every society, is vital in leadership, thus, the role language plays in leadership can never be over-emphasised because it is the medium through which leaders lead, and are understood by their followers. A leader’s language choice to a large extent, accounts for his/her leadership style, and reveals effectiveness/ineffectiveness in leadership. It is on this premise that this study assesses linguistic inference in leadership. Working within the tenets of Halliday’s (1994) Systemic Functional Linguistics (SFL), the study analyzes textual linguistic expressions employed by leaders, revealing thoughts, intents, values, etc. through language use, communication style, and discourse patterns, and how they reflect on leadership. Engaging the qualitative method of data analysis, the study examines the speeches of Nigerian leaders in the political and business sectors - President Bola Ahmed Tinubu and Aliko Dangote’s speeches respectively. Findings revealed that the choice of words of leaders constitutes their leadership style, resulting in effective or ineffective leadership. It concludes that, leaders’ effective communication gives birth to individual/organisational support in leadership which in turn, produces effective leadership. The study recommends that more attention should be given to language use/communication in leadership for effective leadership, and this would also curb enormous generalisation of leadership communication style
Microbial Consortia: A Mixed Cell Catalyst for Biotransformation of Biomass into Biofuels and Chemicals
Get PDFAdding value to waste using environmental biotechnological approaches is a promising concept for its
management. Mixed culture fermentation is the way of utilizing two or more microorganisms as
biocatalyst to produce valuable products from various substrates, including wastes. Mixed culture
fermentation could become an excellent alternative to traditional pure culture-based biotechnology to
enable next generation biofuels and bio-commodity production. This caters the advantages over
application of pure cultures, such as better utilization of the substrate, waste utilization, wider range of
enzymes, ability to attack and convert greater variety of compounds, higher growth rates and product
yield, multistep transformations in a single bioreactor and protection against unwanted contaminants.
This chapter highlights some of the important and recent developments in bio-catalysis 270based on
mixed microbial cultures for biofuel production with a special focus on understanding various factors
that affect the metabolic pathways of mixed cultures fermentation for biofuel production such as ethanol,
butanol, syngas, methane, and hydrogen. The chapter also reviews the technical constraints of the mixed
fermentation process for practical and commercial applications, and applications of genetic engineering
and nanotechnology tools for improving the mixed culture technology

Get PDFThis chapter underscores the current business environment for wine tourism in Tanzania and identifies
opportunities for its establishment using the stakeholder theory based on data from wine
stakeholders.The study’s identification of landscape, vineyards, cultural heritage, and wine festivals as
potential wine tourism attractions provides valuable insights for the development of wine tourism in
Tanzania. It is recommended that policymakers and tourism stakeholders in Tanzania focus on
leveraging these products to establish a thriving wine tourism industry. This can be achieved through
targeted marketing campaigns, investment in infrastructure and facilities, and the implementation of
sustainable practices that preserve and enhancethe natural and cultural resources of the country. The
results of this study could be significant not only for Tanzania but also for other emerging countries
looking to establish and develop their wine tourism industry
E-BANKING AND PERFORMANCE OF SELECTED NIGERIAN BANKS
Get PDFThis research investigates the relationship between E-banking technologies and the financial performance of deposit money banks in Nigeria from 2000 to 2022. The study's objectives include examining the impact of technological tool applications on bank performance, exploring the causal relationships among E-banking tools and bank performance, and assessing the short-term and long-term dynamics between E-banking and bank financial outcomes. An ex post-facto research design was employed, utilizing time series data and econometric techniques analyzed with E-views software. The findings demonstrate a complex relationship between E-banking tools and bank financial performance. Automated teller machines (ATMs) had a negative short-term impact but a positive long-term effect, suggesting that strategic investments in ATM technology are crucial for sustainable growth. Interbank transfers similarly exhibited a short-term adverse impact but a positive long-term contribution to bank performance. Mobile money volume negatively influenced bank performance in the short term but showed a positive impact in the long term, underscoring the transformative potential of mobile banking services. In contrast, web-based transactions showed a positive short-term impact but a negative long-term effect, indicating the nuanced dynamics of online banking on financial outcomes. The study found no clear causal relationship between ATMs and interbank transfers with deposit money bank performance, suggesting that other factors might be more significant in shaping bank financial outcomes. However, a unidirectional causal relationship was observed from mobile money usage to deposit money bank performance, highlighting the significant role of mobile banking in influencing financial outcomes. These results align with previous research, indicating that E-banking technologies offer both challenges and benefits to bank performance. The findings contribute to the broader literature on E-banking by providing insights into the Nigerian banking context, emphasizing the importance of strategic investments in E-banking technologies, and highlighting the pivotal role of mobile banking services in driving positive financial outcomes
