The examination of social capital in hungarian rural communities: the case of Bátya village
Authors: Kassai Zsuzsanna
Published: July 2019

The term ‘social capital’ was first used in the international literature in the beginning of the 20th century by Lyda Judson Hanifan, but it became widely known only in the 1990s and there is still no consensus on how to measure it. In the beginning of the paper a short review can be found concerning the different approaches, definitions and functions of social capital. Then an example for measuring method is presented through a Hungarian case study. In this part, some fundamental social characteristics of the population of Bátya village are examined.
Science-Based Procedure for Designing Tubular Porous Cooling Systems for Thermal Power Plant Equipment Components
Authors: Genbach A.A. , Bondartsev D.Yu.
Published: July 2019

We investigated critical heat flux phenomena in metallic and porous structures characterised by low thermal conductivity. These structures are used to cool various thermal power plant equipment; their operation involves both gravity and capillary forces. The paper describes the failure mechanism in metallic steam generator surfaces and poorly thermally conductive low-porosity coatings made of natural mineral media (such as granite). We determined how heat flows depend on their duration and penetration depth of thermal disturbance. Tubular porous systems are less bulky and feature high intensity, higher thermal conductivity and reliability. We show that for granite coatings the maximum thickness of the particles detached due to compression forces is (0.25...0.3)·10--2 m. The compression curve sections that govern detachment of particles larger than 0.3·10--2 m are shadowed by the melt curve for high heat flows and short exposure times and by the tension curve in the case of low heat flows and short periods of time. The investigation should help us to design porous coatings usable in cooling systems.

The Impact of Social Media Participation on Academic Performance in Undergraduate and Postgraduate Students
Authors: Santoveña Casal Sonia
Published: July 2019

The main objective of this study was to analyse the influence of social media participation on academic performance. The sample consisted of 1960 students taking one of two courses at undergraduate or postgraduate level, respectively (Faculty of Education, National Distance Education University, Spain), of whom 411 students carried out an activity based on social media participation. We used a mixed quantitative (descriptive analysis and ANOVA) and qualitative (content analysis) design. Our results showed that the students who participated in a social media-based activity presented better academic performance than those who did not carry out any activity or who took part in a more traditional learning activity. We conclude that regardless of educational level, social media participation exerts a positive influence on performance. Consequently, it is important to consider the variable of social networking site use because this can partially explain academic performance. We also found that the networks generated during the course did not constitute stable communities of practice. Our main recommendation is that three stages of instruction should be considered when designing a course based on social media participation: beginners, intermediate, and professional.
University Teachers and Open Educational Resources: Case Studies from Latin America
Authors: Rodés Virginia , Gewerc-Barujel Adriana , Llamas-Nistal Martín
Published: July 2019

The Open Education movement has made efforts to systematise experiences and to evaluate the adoption of Open Educational Resources (OER). However, OER adoption is not part of the prevailing paradigm in higher education, both at the global level and in Latin America. This paper describes results of a study that analysed the social representations regarding the development, use, and reuse of OER by university teachers in their pedagogical practices. We conducted a study of 12 cases from Latin American universities using data analysis based on Grounded Theory. The results show that the use and reuse of OER lacks of public and institutional policies. The main agents are teachers organised in teams that support OER adoption. The reasons that encourage the creation of OER are mainly intrinsic, such as the pleasure derived from contributing and sharing, as well as external and related to professional development needs from the reflection on one’s own educational practice. Educators consider it essential to evaluate the resources created so that they can be reused in continuous improvement processes. Commercial use and misappropriation of the works are two of the main tensions identified. The community factor of teaching guides most behaviours in OER adoption in educational institutions and is presented as an inherent part of the development and transformation of the curriculum.
The PERLA Framework: Blending Personalization and Learning Analytics
Authors: Chatti Mohamed Amine , Muslim Arham
Published: July 2019

Personalization is crucial for achieving smart learning environments in different lifelong learning contexts. There is a need to shift from one-size-fits-all systems to personalized learning environments that give control to the learners. Recently, learning analytics (LA) is opening up new opportunities for promoting personalization by providing insights and understanding into how learners learn and supporting customized learning experiences that meet their goals and needs. This paper discusses the Personalization and Learning Analytics (PERLA) framework which represents the convergence of personalization and learning analytics and provides a theoretical foundation for effective analytics-enhanced personalized learning. The main aim of the PERLA framework is to guide the systematic design and development of effective indicators for personalized learning.
Research on MOOCs in Major Referred Journals
Authors: Babori Abdelghani , Zaid Abdelkarim , Fihri Fassi Hicham
Published: July 2019

Over the last decade, several studies have focused on massive open online courses (MOOCs). The synthesis presented here concentrates on these studies and aims to examine the place held by content in these studies, especially those produced between 2012 and 2018: sixty-five peer reviewed papers are identified through five major educational technology research journals. The analysis revealed that these research articles covered a wide diversity of content. Content was mainly defined in terms of objectives of MOOCs, prerequisites required for participation in the MOOC, types of learning scenarios, and, though rarely, through the strategies used to convey content. In addition, empirical studies adopted a variety of conceptual frameworks which focused mainly on learning strategies without relating to the content in question. Finally, content was seldom considered as a research object. These results can provide MOOC researchers and instructors with insights for the study and design of MOOCs by taking into account the specificity of their content.

Pszeudocereáliákból készített innovatív próbatermékek vizsgálata és fogyasztói értékelése
Authors: Jevcsák Szintia , Sipos Péter
Published: July 2019

Kutatásunk célja volt, hogy olyan újszerű próbatermékek előállítását végezzük el, melyek kedvező táplálkozás-élettani hatással rendelkeznek. Elsősorban álgabonák felhasználási lehetőségeinek feltérképezése volt a feladatunk, így a hajdina, az amaránt és a quinoa lisztek voltak a legfontosabb alapanyagok számunkra. Ezen lisztek jellegzetes ízének javítása céljából további gluténmentes lisztek meghatározott arányokban való keverését és próbatermékek készítését végeztük el. Kísérletünk következő fontos célja volt a fogyasztói vélemények felmérése, ugyanis olyan visszajelzést kapunk, mely segítségével meg tudjuk határozni a további fejlesztésünk irányvonalát, hogy próbatermékünk kedvezőbb tulajdonságokkal rendelkezhessen. A fizikai vizsgálatok eredményei azt mutatták számunkra, hogy a kevésbé fogyasztott, nem hagyományos növények lisztjeiből is készíthetünk jó minőségű termékeket. A kémiai vizsgálatok alapján a próbatermékek kedvező fehérjetartalommal rendelkeztek, a zsír- és energiatartalmat további fejlesztések alkalmával csökkenteni kívánjuk. Az érzékszervi bírálat alapján volt, aki a quinoa liszttel készített próbaterméket részesítette előnyben, annak kedvező illata (átlagosan 5 pont) és puha állaga (átlagosan 4,6 pont) miatt, míg volt, aki inkább a ropogós állagot kedvelte (átlagosan 4,6 pont), így az amaránttal készült próbatermék nyerte el tetszését. Összességében elmondható, hogy az organoleptikus értékelés alapján a quinoa (kontroll), a quinoa-rizs (60:40), a quinoa-gesztenye (80:20), az amaránt-rizs (60:40) és a hajdina-rizs (60:40) lisztek felhasználásával készült próbatermékek érték el a legmagasabb pontszámokat. Az adott előkísérletek és a fogyasztói megítélés alapját képezi a további termékfejlesztéseknek, valamint segítséget nyújt feladataink elvégzésében.

Preserving Identity through Modernity: Dayah al-Aziziyah and Its Negotiations with Modernity in Aceh
Authors: Fahmi Arrauf Nasution Ismail , Miswari Miswari , Sabaruddin Sabaruddin
Published: July 2019

This paper aims to analyze the dayah negotiations in Aceh in the face of modernity. On the one hand, the dayah needs to maintain identity by caring for the uniqueness of the system and methods of religious teaching in accordance with methods that have been taught from generation to generation. Text review determined by the dayah teacher (teungku) starting from the criteria of the dayah student (santri) and the system of evaluation and standardization of abilities. Dayah also takes care of identity by forming the personality of the santri through the development of independence of life in the dayah. The dayah system has succeeded in giving birth to a society that understands Islam in a deep, comprehensive and far-reaching understanding of religion. More importantly, dayah education alienates santri from radical thought patterns and makes them tolerant humans. The results of this study show that Dayah Al-Aziziyah who cared about modernity by not losing its identity successfully spread religious teachings well in Aceh. Negotiations with modernity also made Al-Aziziyah a little left with some of its educational principles such as delaying the big vision to make Islamic Higher Educatin (Sekolah Tinggi Agama Islam, STAI) Al-Aziziyah Samalanga exactly like the dayah manyang (higher dayah level) that had been popular in Aceh.
MOVING IJTIHAD AND TAJDID ON AMAL USAHA MUHAMMADIYAH (AUM) IN BUILDING THE CIVILIZATION OF ISLAMIC ECONOMY
Authors: Setyawan Dharma
Published: July 2019

Muhammadiyah declares that the gate of ijtihad (reasoning) and tajdid (modernization) were being yet continued. Ijtihad was the base core to establish the main character of Muhammadiyah as a Modern Islamic Modernization Movement. Then, the establishment on tajdid (modernization) grows as a motor to improve the system of its movement on finding the solution to ideology problem, politic, business, social, cultural, and defence. Muhammadiyah, which the first time moved on social-religious track, was still upbringing to comprehend and rolling in the progressivity of Moslem society as in the case Indonesia. By ijtihad (reasoning) and tajdid (modernization), the role-model of Muhammadiyah as a social-religious movement grows its root on business practice. The Council of Business and Enterpreneurship (MEK) of Muhammadiyah schedules on developing the House for Charity of Muhammadiyah (AUM). Dawam Rahardjo (2000) confirms, a large number of member and institution will represent as a comparative advantage capital resources to the movement of Muhammadiyah. Those resources orchestrate Muhammadiyah as an organization which is not only moves on social-education-and-religious practices, but as well in business and finance. At least, there are two reasons why Muhammadiyah rolls in business practice. Firstly, Muhammadiyah perform to roll in this business merit by the image of intechangible advantages to other charities: as well as schools, hospitals or religious calls. Secondly, Muhammadiyah sustains a potential power to organize those. That is supported by the fact that there are many beureucrates possess in higher structural of Muhammadiyah, the large number of human resources out-put by Muhammadiyah schools, the enterpreneurs possessions, and large number of its members. This paper researches the Muhammadiyah-Nomic, the contribution of ijtihad and tajdid on Charitable Enterprises of Muhammadiyah (AUM) in building the civilization of Islamic economy.
Developing Historical Projects’ Database for Nigerian Oil & Gas Sector-Status, the Imperatives and the New Normal
Authors: Awoyomi Johnson Olu.
Published: July 2019

In today’s competitive business environment every effort and opportunity to improve a company’s capital projects process cycle needs to be explored. It is surprising that since we found oil in Nigeria, there has not been a functional and robust project historical database (owned by the industry) – containing key metrics on: cost, schedule, risk, scope, lessons learnt, etc. The IOCs have theirs but the owner-side is still yet to wake up! This article will propose a way to implement a National Project historical database (NPHDB) system for the Nigerian Oil and Gas sector. The collection of costs, schedules, resources, and technical data from completed projects can facilitate the development of benchmarks, ratios, factors, and other statistical analyses to measure and evaluate project performance and quality. Over time, if we introduce and properly use a project historical database system, individual project performance, as well as corporate decision making in choosing the best projects to pursue, will improve. The proposed National Historical Project Database system for the oil sector will assist the owner project management team (government agencies supervising the government interests in the oil and gas sector) to select the right projects to do in the first place, and then to properly execute the selected projects. The premise of this Paper is that the implementation of a project historical database system will allow the oil sector to improve their project processes in light of the total corporate capital budget and capital management efficiency. You can't improve if you don't know where you've been and how you got there. ‘The sooner we can get started capturing data the better; we shouldn’t let good projects pass us by’.
Occupational deaths from Similar Causes; Why?
Authors: Shittu Ganiyu Adio
Published: July 2019

Understanding why incidents re-occur from similar causes despite the previous experiences, lessons and available tools to ensure that they do not happen again has been a cause of concern for company management for years and different reasons have been attributed to this issue. In recent past, below are few examples of incidents from similar causes.

On 25 January 2012, during the pre-mob inspection of a pile load tester pump by a DIL pile rig operator (Mechanical-24yrs old) with his Supervisor, the unit was put under pressure three times successfully but there was no movement of the pump piston. The pump was put under pressure the fourth time with a declared pressure of 500 bars, the pile load tester flange suddenly gave way and caused several severe injuries to the operator. He was confirmed dead at around 18h30. The unit was brand new with test certificate; IP was trained for it and note that the design pressure of the pile load tester was 690bars. In addition, when the unit failed, the 25 out of 26 bolts of the flange cut off while the last one had its nut pulled out.

On 15 May 2017, a fatal accident occurred when an analyzer engineer removed the cover on an explosion-proof enclosure as part of the routine task for the day. The ~5.5kg weighing threaded cover and with a 14 inches in diameter was propelled forcefully from the enclosure as the Engineer unscrewed it inflicting a fatal head injury. The pressure inside the enclosure from leaking sample gas or instrument air components caused the forceful propulsion of the enclosure cover. There was no gauge or indicator on the enclosure to monitor the internal pressure inside the enclosure and there was no means to relieve internal pressure (http://www.safteng.net/images/2017_Posts_Pics/CVXIndustryAlertJune2017.pdf).
Modification of Hall-Yarborough Equation of State For Predicting Gas Compressibility Factors
Authors: Ayuba Ibrahim , Isehunwa S. O. , Adamu M. B. , Usman A. , Bello M. N.
Published: July 2019

This investigation demonstrates the use of acentric factor as the third parameter in a corresponding states correlation for compressibility factors and a discussion of their application to three different types of gas reservoir.

A correlation is presented which provides compressibility factors based on Hall – Yarborough equation of states for use in both two – phase and single-phase hydrocarbon systems. The modified Hall - Yarborough equation employs the acentric factor as an additional parameter to improve its accuracy. This modified equation is as simple as the original form, yet achieves substantially better prediction accuracy, especially at higher pressure.

The correlation is based on hydrocarbon compressibility determinations from twenty-two hydrocarbon samples taken from three different types of reservoir systems. Out of the data used 67 percent were from dew point or retrograde gas condensate and bubble point or dissolved gas reservoir, 33 percent were from single phase gas reservoir.

Results from the modified Hall – Yarborough equation, the original Hall – Yarborough equation and practically obtained were compared with natural gas components data for three different reservoirs to demonstrate its accuracy and increased application range. The improvement of the modified equation, over the original Hall – Yarborough equation ranges from 0.98% to 7.017% on the average.
Artificial Bee Colony ABC a Potential for Optimizing Well Placement – A Review
Authors: Okoro Emmanuel Emeka , Agwu Okorie E. , Olatunji David , Orodu Oyinkepreye David
Published: July 2019

Many optimization tools exist for well placement into reservoirs for maximum oil recovery. Conventional tools such as simulated annealing, response surface technology, gradient-based optimization, mixed integer programming etc. abound. However, artificial intelligence optimization tools have emerged over the years and are gaining ground. Artificial bee colony (ABC) has become one of the most common optimization methods in the domain of Artificial Intelligence since it was first conceived in the early nineties. As a result, avalanches of researches to its credit in well placement optimization exist. This paper therefore, highlighted conventional well placement optimization tools and also reviewed the artificial intelligence based optimization tools especially ABC and hybrids of ABC Algorithms formulated for well placement and compared them with each other using four basic criteria. The review has shown that ABC algorithms are very efficient in handling the placement of wells in reservoirs during well planning. This work therefore opens up a new vista in the area of well placement optimization and is therefore recommended to anyone looking for a pivot on the well placement optimization discussion.
A Geomodel for Pore Pressure Prediction Based on A Viscoelastic Compaction Law
Authors: Nwonodi Roland I. , Dosunmu Adewale
Published: July 2019

It is important to develop a model that simulates in situ pore pressure profile especially in an overpressured interval mainly because of wellbore instability, hydraulic fracturing treatment, lost circulation, kick, and blowout. The current methodology for predicting pore pressure depends on the Terzaghi's total stress but requires the accurate determination of the effective stress in the rock. The sedimentary processes occurring in a basin put the rock under compaction, which can be viscoelastic. The normal-compaction methods of predicting pore pressure consider only mechanical compaction, but viscous compaction is important to consider, especially beyond 2000 meters of the subsurface. In this study, a model for predicting pore pressure was developed by applying an effective stress law that considers viscoelastic compaction into the Terzaghi's stress equation. From the relationship defining effective stress and the rate of deformation, the author posed an expression for the total effective stress in terms of time. The applicable boundary condition was with respect to the transit time through the rock. Using transit time data for a Gulf Coast wellbore at 10,000 ft yielded a pressure gradient of 0.885 psi/ft, which compares to 0.863 psi/ft obtained from the modified Eaton's model and 0.9132 psi/ft obtained from the Zhang model. Another pressure required for a wellbore at 30,000 ft yielded a pressure gradient of 0.535 psi/ft, which compares with 0.52 psi/ft obtained from measured formation pressure. Thus, the results indicate that the viscoelastic compaction accurately defines the pore pressure profile in a rock. Furthermore, simulation results indicate that the most important variable affecting pore pressure is the overburden stress.

Magnetic resonance (MR) is a very robust service that delivers several formation evaluation products. Both the wireline (WL) and logging-while-drilling (LWD) services deliver shale volume, porosity, permeability, viscosity, saturation and fluid typing. In addition to these, the WL service also delivers capillary pressure and grain size analysis.

Although WL and LWD MR Services have different modes of acquisition, the result is usually the same. WL MR uses multiple frequencies, but LWD MR uses a single frequency. Multiple frequencies provide multiple magnetic field gradients that provide for more flexible hydrocarbon typing acquisition sequences, unlike the LWD MR single frequency that supplies a single hydrocarbon acquisition sequence.

Dual Wait Time (DTW) analysis is the hydrocarbon typing technique for LWD MR, but the WL hydrocarbon typing has the flexibility to choose from a range of applications that includes two-dimensional MR mapping (2D MR), density multiple wait time (DMTW) analysis, multiple gradient inter-echo spacing (MGTE) analysis, simultaneous inversion of multiple echo trains (SIMET), and T1/T2 ratio (R-T2) analysis for gas reservoirs.

Light hydrocarbons (gas) and Kaolinitic shales compromise the use of neutron-density and gamma ray models as bulk shale volume indicators. However, MR shale volume computation using clay-bound water (CBW), which is unaffected by the presence of gas or Kaolinitic shales. MR Logs can accurately determine porosity in complex lithologies and thin beds. Irreducible water saturation from MR is used to determine reservoir quality and productivity.

In the industry today, MR logs are the most tolerant to environmental challenges. They are able to "say" the true state of the reservoir in the midst of environmental factors like the presence of gas, shales, and thin beds, which are known to adversely impact measurements from other conventional tools
Dynamic Production Forecasting using Artificial Neural Networks customized to historical well Key Flow Indicators
Authors: Nnamdi David N. , Adelaja Victor O.
Published: July 2019

The existing decline curve analysis (DCA) equations, some with valid theoretical justifications, cannot directly react to changes in operating conditions. Thus, they all assume constant operating conditions over the flowing life of a well. This however is an obvious oversimplification.

This paper begins by briefly reviewing Gilbert's equation for flowrate prediction and then the C-curve and Logistic growth model DCA theories. The above review serves to identify well key flow indicators (KFI) and performance drivers. Subsequently, a forecasting approach which involves building artificial neural network (ANN) frameworks and training them on well KFI data is presented.

Using trained ANNs, production forecasts were generated for three oil wells in the Niger-Delta producing from separate reservoirs under different flow regimes. The results were compared to forecasts from traditional DCA methods and material balance simulation, as well as with future production from the wells themselves. The results indicated that trained ANNs are capable of generating better performance curves than traditional DCA, with forecasts tying closely with results of material balance simulation and measured future well production rates. The ability of trained ANNs to evaluate the effect of changes in operating conditions (i.e. FTHP, GOR and water-cut) on production profiles and reserves drainable by wells, allows for scenario forecasting which is invaluable in field development planning. This is illustrated with field cases.

This paper also presents a novel approach to evaluating the optimal hyperparameter configuration (i.e. the number of layers, neuron count per layer, dropout, batch size and the learning rate) required to minimize the loss function whilst training an ANN on any given dataset. This should prove invaluable to engineers and geoscientists integrating deep learning into sub-surface analyses.

This paper demonstrates how 280ft of oil column spread unevenly across multiple and differentially depleted reservoir units separated by shale layers of varying thicknesses in a highly deviated (62 deg.) well was perforated in a one trip system and how the project cost was minimized by achieving multiple perforations in a single trip whilst retaining capacity to effectively cure losses and mitigating post-perforation well control risks. Against the conventional perforation methodology where reservoir units are perforated individually, isolated before carrying out the next perforation in the subsequent reservoir. The one trip system was designed and deployed in one run targeting all the 6 separate carefully selected sand lobes in one run ensuring good standoff from the contact and zonal isolation behind casing. Successful execution was confirmed with all the expected physical outcomes which includes pipe vibration, brine loss as well inspection of the spent guns. A post perforation noise and production logging also confirmed flow across all planned perforation intervals. Perforation of a highly deviated well in differentially depleted multi-lobed reservoirs present significant operational risks. This paper illustrates how one can safely collapse multiple conventional perforation runs into a single trip with its attendant benefits on cost efficiency, crossflow and well control. This is the first of its kind in a swampy terrain, shallow offshore Niger Delta.

This study highlights a technique adopted for predicting and mapping net-to-gross (NTG) away from well locations through a combination of rock physics and seismic inversion applied in the Baza Field. The Baza field is located offshore Nigeria, with reservoirs poorly to mildly consolidated that were originally deposited in a deep-water submarine canyon system. The field is a partially appraised green field with three well penetrations encountereing amalgamated channels and lobes within the canyon system of tuiditic origin. Of the three wells drilled to date, only one well penetrated the key reservoir of interest- the B4 sands. The paucity of well penetration posses a challenge for accurate reservoir property assessment, particularly net-to-gross that has direct impact on hydrocarbon volume computation and ultimately on field development.

Net-to-gross was predicted from seismic data based on a linear relationship observed from log derived P-impedance-AI (density × compressional velocity logs) and S-impedance-SI (density × shear velocity). Both properties when integrated can descrimate between sands and shales, and therefore serves as a proxy for calculating NTG. The linear relationship was applied to AI and SI seismic volumes built from simultaneous inversion of three sub-stack seismic data – the near (0-18), median (12-24) and far (24-45).

The seismically derived net-to gross computed from simultaneous inversion compares favorably with log derived net-to-gross at well locations. The net-to-gross model resulted in a robust static and dynamic model that ultimately formed the basis for selecting optimal locations for future development wells for the B4 reservoir.
Mathematical Modelling of Oil Viscosity at Bubble point Pressure and Dead Oil Viscosity of Nigerian Crude
Authors: Adeeyo Yisa
Published: July 2019

Traditionally, reservoir engineering fluid flow calculations use viscosity data. However, in the absence of lab/experimental data other available derived correlations are used to predict the PVT property. Limit on the number of available data, regional peculiarity of the fluid, several viscosity correlations in the literature have limited accuracy and applicability. This study has developed predictive models using more than 2020 unpublished PVT data sets from different locations in Nigeria in rigorous nonlinear regression modelling. Different nonlinear algorithms, modified Newton-Raphson nonlinear least-square data fitting approach; Levenberg-Marquardt algorithm were used to develop new models for the estimation of the viscosity at the bubblepoint pressure and dead oil viscosity. The results of the performance of the model for viscosity at the bubblepoint show that the model provides better prediction with average absolute relative error of 21.06 and coefficient of correlation of 0.98 and the dead oil viscosity model shows a substantial improvement with average absolute relative error of 30.06 and coefficient of correlation of 0.90 over published correlations.

Authors: Okiotor M. E. , Asuen G.O.
Published: July 2019

The present investigation focused on geochemical evaluation of shale sequences in The Lower Benue Trough using geostatistical approach Thirty two representative samples of shale sequences of The Asu River Group, Nkporo Group and Mamu Formation in The Lower Benue Trough were subjected to Multi-Parameter study in an attempt to present a model of the sediment provenance, and paleoenvironment diagenetic conditions.

The X-ray diffraction and Inductively Coupled Plasma Mass spectrometry (ICP-MS) techniques were employed to examine and establish qualitative and quantitative constituents of the Major oxides, Trace and Rare Earth elements. The major minerals determined include SiO2 (40.96%, 56.08% & 60.39%)2, Al2O3 (15.09%, 18.27% and 21.16%), TiO2 (0.75%, 1.73% and 1.63%) and Fe2O3 (9.66%, 2.78% & 2.85%), for Asu River Group, Nkporo Group and Mamu Formation respectively. The studies suggest high influx of sediments into both The Abakaliki Anticlinorium and the Anambra Basin. When tested with multivariate statistical techniques such as Factor, Principal Component, Correspondence and Cluster analyses, the hidden affinities within the sediments were revealed in terms of similarities and dissimilarities. Enrichment and depletion of biogenic indicators CaO (EF=1.87 − 0.01) and P2O5 (EF=1.58 − 0.33) in the studied Asu River Group and Anambra basin sediments indicate deep marine to marginal marine paleoevironment of deposition respectively. Chemical examination of the maturity indexes indicate that the Anambra basin sediments were more matured, indicating that most of the Anambra Basin sediments were reworked from the Abakaliki Anticlinorium.

Published: July 2019

This study examines the levels of vehicular Carbon (IV) oxide (CO2) emissions in nine (9) selected locations characterised by high traffic congestion in Benin City Metropolis, Edo State, Nigeria. The contributory effects of these emission levels on climate change and air pollution were also assessed based on global standards. CO2 concentration measurements were conducted twice a day, four times a week, for a period of sixteen (16) weeks. Results showed that the highest average mean values were recorded at Ring Road, New Benin and Third East Circular Junctions with 1421 ppm, 1417ppm and 1171ppm respectively in the morning hours and 1767ppm, 1417ppm, 1217ppm respectively in the afternoon hours. Diurnal variations revealed significant statistical differences (P<0.05) for CO2 emissions generated at different times of the day. Spatial variations in the CO2 data were also statistically significant (P<0.05), with the highest mean concentrations of 1594ppm reported for Ring Road sampling station while New Benin and Five Junction sampling sites recorded mean CO2 emissions rates of 1417ppm and 745.8ppm respectively. The results showed that CO2 emission levels at these selected high traffic areas in Benin are approximately five times more than the internationally accepted safe limits of 350ppm for atmospheric CO2. However, these levels are less than the Occupational Safety and Health Administration (OSHA) permissible exposure limits of 5,000ppm. High vehicular exhaust emission which is the primary source of CO2 in the Benin city metropolis can be attributed to poor traffic handling and discipline; and low dilution and dispersion of the emitted CO2 due to prevalent low wind speeds in these study locations.
