Effects of comparative advantage on exports: A case study of Iranian industrial subsectors
Authors: Nonejad Masoud
Published: January 2020

One of the informational requirements in planning import and export activities is to an awareness of a countryâ€™s comparative advantage in the production of goods and services. The present paper attempts to assess Iranâ€™s Revealed Comparative Advantage (RCA) in industrial subsectors based on two-digit code of the International Standard Industrial Classification (ISIC) and effects of five top subsectors with the highest average of RCA on the total Iranian real industrial exports. RCAs for Iranian industrial subsectors (during 2001-2010) were calculated for 2001-2010 time period and seasonal data (2001- 2010) were collected to estimate the RCA Model. Auto Regressive Distributed Lags (ARDL) Method was employed to investigate the effects of these subsectors on the total Iranian real industrial exports. The econometric results show that the subsectors with highest RCA average have a positive and significant effect on the total Iranian real industrial exports.
Unequal Regional Development in Rural Vietnam: Sources of Spatial Disparities and Policy Considerations
Authors: Long Hoang Van
Published: January 2020

In Vietnam, the poor have long been assumed to be the ethnic minorities mostly living in the highlands. After more than two decades of introducing Doi moi1 policy into the economy, along with having enjoyed various improvements in social and economic aspects, the disparities between the majority and ethnic majorities, the lowlands and the highlands, and between regions, still have been widened. This paper aims at examining sources of spatial disparities in rural areas, and exploring the current situation of regional economic development using both development policy review and econometrics approaches. Data from Vietnam Household Living Standard Survey (VHLSS) 2008 was used in the study. The expenditure per capita was employed as the dependent variable to regress with household characteristics and resources in order to obtain the effecting factors. In addition, the regional dummy variables were employed to show the effects from different geographic locations. The results showed that the household characteristics and resources such as education level, perennial land area, water surface area, and the accessibility to infrastructure facilities such as road, electricity and local market had positive effect on the expenditure. Furthermore, the North Central Coastal region showed negative impact on household expenditure. Interestingly, this finding does not absolutely follow the hypothesis and indicates that the economic development strategy and polices should be adjusted to decrease the gap among regions based on their economic advantages for balancing the economic situation of the whole country in the future.
Dollarization and the Zimbabweâ€™s Economy
Authors: Sikwila Mike Nyamazana
Published: January 2020

This paper examines the economic impact of the inception of the full dollarization1 in Zimbabweâ€™s economy after the effects of hyperinflation and an unprecedented depreciation of an exchange rate between 2000 and 2008. Dollarization is a generic word implying the use of any foreign currency as legal tender instead of the domestic currency. An analytical qualitative approach was adopted for this study. The analysis of the benefits and costs of dollarization to Zimbabweâ€™s economy revealed how dollarization has impacted on the stabilization of Zimbabweâ€™s economy. This article also highlights the fact that Zimbabwe is not the only country in Africa that has had to resort to adopting foreign currency as legal tender in an effort to remedy macroeconomic imbalances. To our knowledge, there is scant literature on dollarization in Africa and this is the reason why we have chosen to examine the impact of dollarization on Zimbabweâ€™s economy. In addition, we add to Kurt Schulerâ€™s work (2005) by indicating the other African countries that had adopted dollarization over the years. Furthermore, the study offers support to recent literature that asserts that economic stabilization in these countries resulted from the impact of dollarization. The results of the study revealed that dollarization positively impacts on the countryâ€™s economy. In particular, this study is important to policymakers in that it sheds some insight into the importance of a strong currency and stable exchange rate for the stabilization of economies that experienced hyperinflation.

Growth Governance Nexus: A Case of Pakistan
Authors: Nazir Rabia , . Mumtaz Anwar
Published: January 2020

Good governance has gained tremendous importance in the development agenda of developing economies since 1990s but growth literature gives mixed picture about the role of governance and institutional factors in explaining GDP growth. The present study is an attempt to provide empirical evidence on interlinks between governance and GDP growth. ADF and Johansen co-integration tests are applied for econometric testing of the hypothesis by using time series data from 1984 to 2010. All the variables turned out to be significant with ICRG (proxy used for governance) having positive and significant impact on GDP growth of Pakistan. Results of the study have shown that governance plays major role in determining GDP growth pattern of Pakistan. A complete reform of the political, economic system, judiciary, bureaucracy and a free media are recommended to improve governance and to achieve sustained GDP growth in Pakistan consequently.
Convergence or Divergence? Evaluation of Human Resource Practices in Turkey
Authors: Tayfur Ozge
Published: January 2020

This study investigates human resource (HR) management (HRM) practices in Turkey vis-Ã -vis history, religion, culture, and economic systems. It hopes to contribute discussion on convergence and divergence by assessing traditional valuesâ€™ impact on shaping HR practices. The study reviews the journal articles, thesis and conference proceedings addressing major human resource functions, namely job analysis, training, performance-management, recruitment and selection in Turkey. Review suggests directional convergenceâ€™s presence, meaning companies in Turkey follow the same trends prevailing in the USA or Europe, yet the patterns differ with respect to Turkish firmsâ€™ understanding and implementation of these trends. Collectivism, paternalism, and uncertainty avoidance seem to profoundly impact HRM practices in Turkey, decreasing the possibility of full convergence. HR literature is dominated by U.S. and European-oriented research. As this study provides a detailed, though not comprehensive literature review concerning HR practices in Turkey, its conclusions also may be extrapolated to countries with a similar socio-cultural dynamic, in addition to suggesting avenues for future research.
Social Value Creation and Institution-Entrepreneurial Dynamics in a Three Sector Economy
Authors: Dafuleya Gift
Published: January 2020

This paper attempts to answer the question: who creates social value in an economy, for whom and how? By examining the focal institutions that operate in a three sector economy, the paper, at the risk of oversimplifying and over narrowing the scope, develops an institution-entrepreneurial matrix that categorise institutions and provides clarity on the field of play. Coupling this with an institutions-actions model, the paper creates two scenarios of institution-entrepreneurial dynamics within the context of social value creation. The analysis demonstrate that mission drifts that adjust the realm of organizations are inevitable, but need to be carefully managed to avoid mix-up on who does what, for whom and how. At the heart of the discussion is the role of social entrepreneurs whose creation of social value to the segment of humanity in an unjust equilibrium is slightly distinct from the rest. Their unique realm lies in the realisation of nuanced pare to improvements.
Optimal Inflation Threshold for Economic Growth in Malawi
Authors: Nkume Jean-Baptiste
Published: January 2020

There is near consensus in the literature that high levels of inflation (above 40%) affect economic growth negatively. The effects of low and moderate inflation, however, are ambiguous. Nonetheless, several studies have found that low levels of inflation are positively correlated with economic growth, which suggests the existence of a curvilinear relationship between inflation and economic growth. This study sets out to find the threshold level of inflation that is consistent with optimal and sustainable economic growth in Malawi. Using annual time series data for the period 1980 to 2013 and the Conditional Least Squares method, the study finds an optimal inflation threshold level of 17 percent for the country. The study results show that gains in real GDP growth below the optimal threshold level are greater than gains above the threshold level, which is consistent with the theoretical expectations of the threshold estimation model and other empirical studies. Unlike similar optimal inflation threshold studies, this study carries out structural change tests (using the Vogelsang approach) prior to estimating the threshold model. The data are also tested for unit roots using the Zivot and Andrews test for unit roots with a single structural break, and the Lumsdaine and Papell test for unit roots with multiple structural breaks.
Antecedents of Quality Information Sharing in the FMCG Industry
Authors: Mbhele Thokozani Patmond
Published: January 2020

Information sharing in a retail supply chain presents challenges of mapping information flow in terms of collection and transfer capabilities from one point to other internal and external users. Efficient mapping information flow seems to be dependent on information availability, velocity and the level of volatility. This would strengthen partnerships between the upstream and downstream sites of a supply chain in terms of information capturing, transformation and exchange between both internal and external supply chain users. This study examines the relative magnitude of advance economic information sharing in optimizing integrated supply chain activities in the consumer goods industry. It further analyses the challenges of bullwhip effect from the perspective of electronically-enabled supply chain management (eSCM) systems and information sharing in the fast moving consumer goods (FMCG) industry. The study finds that information sharing is related to supply chain performance targets in the FMCG industry in terms of a higher order fulfillment rate and achieving shorter order cycle time through integrated e-SCM systems. The managerial implications of this study are that integrated IT infrastructure capability and top management support (in terms of visible involvement, commitment and participation of executives and the allocation of the necessary resources) are significant antecedents of the quality of shared information.
The Association between the Socioeconomic Status and the Magnitude of HIV AIDS in Kinshasa
Authors: Ayikwa Christian , . Ben J van Rensburg
Published: January 2020

Researches devoted to the HIV/AIDS issue divide the scientific community between the supporters of an association socioeconomic status-HIV/AIDS and those estimating that there is no pattern between them. Studies conducted across the worldâ€™s most affected regions assert one another opinion on the basis of findings scientifically proven. In addition, some other studies argue that the link poverty-HIV/AIDS is vicious, meaning that poverty cause HIV/AIDS and vice versa. The present study conducted in Kinshasa, one of the African cities characterised by a certain level of poverty, aims at investing the potential correlation socioeconomic status and magnitude of HIV/AIDS in its specific context as well as contributes to the debate that took place in the scientific community between both mainstreams evoked previously. Although the study found no relationship between people socioeconomic status and either their sexual behaviour, HIV/AIDS knowledge (3 variables), accessibility to information or availability of condoms, as well as no statistically significant difference between socio economic groups in these mentioned variables, it estimates that it is all matter of space and time rather than pronouncing a judgement about who is right or wrong. Therefore no one is wrong, all are right.
The Association between Maternal Mortality and Non-Medical factors in African Countries
Authors: Lalthapersad-Pillay P.
Published: January 2020

The medical expertise to treat to complications arising from pregnancy and childbirth has not spared girls and women in developing countries from dying of such conditions. Developing countries account for the bulk of the global share of maternal deaths with complications of pregnancy and childbirth being the leading cause of death in young women aged between 15 and 49. Sub-Saharan Africa is responsible for nearly three-fifths of all global maternal deaths which have saddled it with notoriously high levels of maternal mortality ratios, a concern that has been red-flagged internationally and regionally. Most studies on maternal mortality in Africa have been confined to an examination of factors impinging on maternal mortality from both medical and socioeconomic standpoints for individual countryâ€™s based on survey data. Our study differs from others as it employs logistic regression to look at the association between non-medical factors and maternal mortality nationally for all African countries. Whilst the results from the logistic regression suggests that there is no statistically significant relationship between any of the variables and maternal mortality, the odds ratio for Human Development Index (HDI) and Gross National Income per capita (GNI) imply that African countries with low HDI are about three time more likely to have high maternal mortality compared to high HDI countries. Similarly, African countries with low GNI are about five times more likely to have high maternal mortality compared to high GNI countries.
A Theoretic Extension and Empirical investigation of conducting Business Online Social Network: The Continuance Intention Phenomenon
Authors: Assensoh-Kodua Akwesi
Published: January 2020

Online Social Network (OSN) is a web 2.0 enabled technology that permits OSN participants to interact with both old and new friends initially. This model of OSN ventured into conducting business activities on platforms, which resulted in many springing up but not surviving, yet the explosion of business activities on these platforms continuous to grow. It is therefore important that OSN practitioners and researchers understand the key determinants of OSN business transaction and continuance intention propellants. The purpose of this paper is to establish the factors that determine OSN participantâ€™s continuance intention to do business on OSN platform. The research framework is grounded in an extended expectation-confirmation model (ECM). An online survey model was used to collect 300 valid responses from OSN participants who have ever conducted business using OSN. A partial least square version 2.0.M3 (PLS) and Warp PLS 4.0 were deployed to perform CFA analyses and structural equation modelling, respectively. The emerging results provide significant evidence in support of the five out of nine factors tested against the hypotheses proposed, namely: Perceived Behavioural Control (0.01), Satisfaction (0.14), Expected Benefit (0.15), Social Norms (0.24), and Habit (0.31), as the main determinants of OSN continuance intention.
Precision, Consistency and Bias in Emerging Equity Markets
Authors: Nel WS , . NJ le Roux
Published: January 2020

The use of multiples is a popular approach employed by analysts to perform valuations. These multiples are based on optimal value drivers, the valuation performance of which should be underpinned by empirical findings from carefully designed, unbiased research initiatives. This paper firstly investigates the risk of biasing the design of market-based studies which aim to test the valuation performance of individual value drivers. The evidence revealed that, when testing the valuation performance of value drivers, there is an inherent risk of biasing the design of a study of this kind, and therefore, its outcome. Secondly, the paper presents evidence in support of the consistency of previous research findings regarding the valuation performance of individual value drivers in the South African market over the period 2001-2010. To this end, the paper introduces a new approach for the analysis of multidimensional equity valuation research data in the form of principal component analysis (PCA)-based biplots. Thirdly, the paper provides evidence that multiples-based modeling seems to be biased to the downside, which is an important consideration for analysts who choose to adjust their valuations outside of these models.
The Enhancement of Conference Tourism activities as a means to Bolstering Business Tourism in South Africa: A Case Study of Conferences within KwaZulu-Natal, South Africa
Authors: Tifflin Wayne B.
Published: January 2020

Business Tourism is considered an important aspect of a Destinationâ€™s Competitiveness. However having a competitive advantage does not guarantee success (Ritchie and Crouch, 2003). Destination success requires a well formulated competitiveness strategy which is effectively implemented (Seymour, 2009:2). Business tourism and its elements (meeting, conference, and convention centres) need to be managed effectively to provide a destination with a competitive edge. Thus it is important to determine the effectiveness and suitability of conference centres and destinations from the perspective of the delegate. This paper examines the responses of delegate of 49 Conferences in relation to the facilities at the International Convention Centre in Durban, KwaZulu-Natal and the city of Durban as a conference destination. Whilst the broader concept of Business Tourism may encompass more than conferences as a business activity, this paper will show the need for â€œConference Tourismâ€ as significant component to Business Tourism. KwaZulu-Natalâ€™s meetings and conferences are one of the most important attractions and activities of domestic and international tourists. This is clearly illustrated in the following tables:

Local Economic Development: A Conceptual Re-Articulation
Authors: Plaatjie Sebeka Richard
Published: January 2020

Local economic development (LED) in the context of the development question is generally celebrated as a silver bullet to development challenges in Africa. However this discourse is more complex and needs greater theoretical scrutiny in order to understand its meaning. This paper picks up standpoint theory to critique the dominant understanding/s of local economic development and argues that unless it is more people-centered and benefits the local human/s, local economic development will remain an imposition from the top which will continue to alienate the local human and will remain an imperial project.
The Level of awareness of green marketing and its managerial implications amongst selected South African manufacturing Small, Medium and Micro Enterprises (SMMEs) in KwaZuluâ€“Natal
Authors: LEKHANYA Lawrence Mpele
Published: January 2020

The focus of this paper is to present an exploratory study on the level of awareness regarding green marketing and its managerial implications, among selected, South African Manufacturing Small, Medium and Micro Enterprises (SMMEs), in the province of KwaZuluâ€“Natal (KZN). The concept of green marketing and thought provoking managerial implications are still an issue of concern in the South African manufacturing sector. The study aimed to explore the awareness levels about green marketing by selected South African manufacturing SMMEs in KZN, and the resulting managerial implications. Primary data was collected from 84 manufacturing SMMEs. This research was quantitative in nature and a questionnaire was used to collect data from SMMEs owners/managers in KZN. Findings of the research indicate that SMMEs in the study are aware of green marketing and its managerial implications. It further reveals that SMMEsâ€™ owners/managers indicate that the South African Environmental Act and Consumer Protection Act are additional factors that influence their businesses operations. The paper will benefit SMMEs owners/managers, SMMEs marketing managers, and affiliated stakeholders, by introducing a new understanding of green marketing and how to cope with the demand of new green marketing strategies. Most work on the Green Zone has concentrated on green products, with little emphasis on green marketing and its implications. The findings are limited by the studyâ€™s exploratory, quantitative nature and small sample. Generalisation should be done with care and further research, with a large sample and consideration of other provinces, is therefore recommended.
The Impact of Monetary Policy on Financial Market in South Africa: A VAR Analysis
Authors: Noumbissie Flavien Fokou
Published: January 2020

Like in many other countries, the South African financial market facilitates the process of raising capital by channelling funds to more productive economic activity, thereby building the nation's economy while enhancing job opportunities and wealth creation. The aim of this paper is to assess the impact of monetary policy on financial market in South Africa. It is important to constantly look into this interaction since policy decisions have a direct influence on financial market. A negative response from the market side may jeopardise economic stability. The study uses the vector autoregressive (VAR) model to evaluate the impact of monetary policy on financial market in South Africa. The model consists of five policy instruments as variables; namely: money supply (M3), real exchange rate(ER), discount Rate (R), consumer price index (CPI), gross domestic product (GDP) and the two market related variables: Stock market turnover (S) and Bond market turnover (B). Data is obtained from SARB and OECD databases for a period of 53 quarters from 2000:Q1 to 2013:Q1. By the use of impulse response function (IRF), the study found that given current economic situation in South Africa, stock market turnover reacts positively to money supply; discount rate; real exchange and GDP shocks. On the other hand stock market turnover reacts negatively to CPI economic shocks. To correct CPI negative impact on markets, we suggest that the policymakers could envisage a contractionary monetary policy translated by a proportional cut in money supply through the sales of government securities.
Efficiency and Profitability of Tanzanian saving and Credit Cooperatives: Who is a Star?
Authors: Marwa Nyankomo
Published: January 2020

The objective of this paper is to evaluate and benchmark the performance of Tanzanian Saving and Credit Cooperatives (SACCOs). Measuring the performance of these organizations is useful in helping them to monitor and control their performance and business processes and improve productivity and profitability. The study used secondary data from audited financial statements from 103 SACCOs. Technical efficiency was estimated using the data envelopment analysis approach and profitability was measured using return on assets. Then an efficiency-profitability matrix was employed to distinguish best performers from struggling SACCOs. This particular approach has been selected to account for multiple dimensions of performance measures. Using the top 25% as a cut-off for profitability and efficiency we found that only 12% of the firms were diagnosed as best performers (stars). The majority of the firms (61%) were classified under the low efficiency low profitability category. Fourteen SACCOs were highly profitable but had low efficiency scores, which demonstrate a potential for performance improvement by increasing their efficiency. Another group of 14 SACCOs were classified as potential candidates for divestiture because they had high efficiency scores but low profitability. Conclusively the performance of the industry in Tanzania needs a well-thought turnaround strategy to make it commercially viable. For the majority of the SACCO both profit-increasing and efficiencyincreasing strategies are required.

Neural Networks in Accounting: Clustering Firm Performance Using Financial Reporting Data
Authors: Dameri Renata Paola , Garelli Roberto , Resta Marina
Published: January 2020

This paper considers the use of neural networks—namely self-organizing maps (SOMs)—to analyze and cluster firms' financial performance. Applying SOMs to financial statement data is a consolidated practice; however, in this paper SOMs are used to overcome several limitations encountered in previous works on financial reporting indicators such as the small number of companies in the sample, the limited number of ratios, the homogeneity of the economic sector, and the lack of explanation and further analysis of the SOM outputs. This study uses a large financial dataset related to more than 3,000 companies belonging to every economic sector; it demonstrates that SOMs can effectively process a large dataset of heterogeneous data. Moreover, the SOM results are supported by detailed explanations of the research methodology applied, and further traditional financial analysis addresses the black box nature of the SOMs and can help professionals in the understanding and use of SOMs.
Læreres refleksjoner om læring og undervisning
Authors: Johannessen Wenche Hammer
Published: January 2020

Målet med studien er å utforske kvaliteten på ungdomsskolelæreres refleksjoner i en video-stimulert refleksjonssamtale (VSR-samtale). Dette gjøres i lys av lærernes oppfatninger om læring og undervisning. En reflektert lærer er bedre til å ivareta ulike elevers læring (Schön, 2001; Timperley, Wilson, Barrar & Fung, 2007). I profesjonell læring er derfor kvaliteten på refleksjonen avgjørende. Studien bygger på en tematisk innholdsanalyse av seks individuelle VSR-samtaler mellom lærere og forsker. I studien identifiseres to refleksjonsmønster: et handlings- og målorientert refleksjonsmønster og et lærings- og elevorientert refleksjonsmønster. Funnene diskuteres i lys av Larrivees (2008) refleksjonsnivåer: «non-refleksjon», «overflate-refleksjon», «pedagogisk refleksjon» og «kritisk refleksjon». I studien argumenteres det for at lærerne i varierende grad er i en profesjonell læringsprosess. Funn indikerer at lærernes refleksjoner utvikles fra spontane kommentarer til et mer reflektert nivå når de gjennomgår videoopptak i samtale med forskeren.
English abstract
English title: Teachers reflections on learning and teachingThe object of the study is to explore lower secondary teacher’s levels of reflections in a VSRdialogue in light of their own beliefs about learning and teaching. Being a reflective practitioner make teacher’s capable of providing good learning possibilities for all students. The quality of reflections is crucial becoming a “Reflective Practitioner” (Schön, 2001; Timperley et al., 2007). A thematic content analysis draw on six individual VSR-dialogues. Two reflection patterns are identified: An action and goal oriented reflection and a learning and student oriented reflection. Generated data are discussed in light of Larrivee’s (2008) reflection levels: “non-reflection”, “surface-reflection”, “pedagogical reflection” and “critical reflection”. Findings suggest that the teachers’ reflections develop from spontaneous comments to a more reflected level as they review video recordings in a dialogue with the researcher.

Authors: Irawan Erfanda , Mansur Irdika , Hilwan Iwan
Published: January 2020

Acacia mangium Willd. is categorized as an invasive species in the revegetation area of coal mining. The presence of A.mangium causes a shortage the organic matter in the revegetation area. The abundance of A. mangium biomass could be used as a source of organic material for soil enhancer to improve soil fertility. The objective of this study was to develop allometric models of Acacia mangium and to estimate the potential above-ground biomass of A. mangium in PT Wahana Baratama Mining (PT WBM). This study was conducted in February-April 2019. A. mangium population and distribution were collected through vegetation inventory with 0.5% sampling intensity. The allometric models were established using a destructive method. The above-ground biomass allometric model for the four diameter classes are as follows: seedlings (B = 0,002002 - 0,02469D + 0,07322D2 with R2(adj)= 99,38%), saplings (B = 2,754 - 1,742D + 0,4093D2 with R2(adj)= 99,89%), poles (B = -9,16 - 1,153D + 0,5007D2 with R2(adj)= 99,96%), and trees (B = 0,134741D2,38 with R2(adj)= 96,94%). The allometric models were used to estimate the above-ground biomass potential total of A. mangium by using inventory data. The inventory result showed that the mean density of A.mangium is 13.187 individuals/ha with a mean diameter of 5,64 cm. The potential above-ground biomass of A. mangium in PT WBM revegetation area is estimated at up to 51.022,59 tons. The above-ground biomass of A. mangium has potential value to be utilized as a soil enhancer as well as meet the needs of organic material for the whole PT WBM revegetation areas.Keywords: above-ground biomass, coal mining, Acacia mangium, reclamation, revegetation

Artisanal small-scale gold mining tailings frequently used hazardous toxic materials that could contaminate land, rivers, and lakes which harmful to the environment and health. Phytoremediation is one way to overcome the mining waste. Mangium (Acacia mangium Willd.) is one of plant that often used for mining land phytoremediation. However, it was difficult for mangium to be able to survive on land with such extreme conditions, therefore additional input is needed. Using ectomycorrhiza fungi could be an alternative. This study aimed to measure the adaptation of mangium in gold mining tailings and analyze the function of ectomycorrhiza (Scleroderma sp.) in the growth of mangium. The experimental design used a completely randomized design with six growth media as treatments with five replications. The growth media used were: (1) topsoil with mycorrhiza, (2) topsoil without mycorrhiza, (3) topsoil + tailings with mycorrhiza, (4) soil + tailings without mycorrhiza,(5) tailings with mycorrhiza, and (6) tailings without mycorrhiza. Data were analyzed statistically using analysis of variance followed with a Least Significant Difference test. The results showed that the survival rate of mangium life in tailing media with mycorrhizae was fairly high with a percentage of life reaching 60% even though the growth was less when compared to topsoil media with mycorrhiza that reached 100%. The highest growth rate was achieved by mangium in topsoil media without tailings and mycorrhiza (control). This research showed that ectomycorrhiza did not have any significant effects on mangium growth in gold tailing.Keywords: Acacia mangium, ectomycoriza, gold tailings, phytoremediation, Scleroderma sp.

This Research investigated the adsorption capacity of locally prepared adsorbents from Egg shells for the removal of fluoride ion in well water. It evaluated the performance of these adsorbents calcinated at 3000C and modified with 1.0M HNO3 (trioxonitrate (v)) acid. Batch adsorber was used to allow for interaction between adsorbent (grounded Egg shells) with water containing fluoride ion. The batch experiment was performed with particle size of 2.12 contact time (60, 120, 180, 240, 300min), mass dosage (5g, 10g, 15g, 20g) and temperature (250C, 300C, 400C, 500C). The modified adsorbent was characterized to determine the physiochemical properties of grounded Egg shells (GE). Also the chemical composition of the modified adsorbent was analyzed to determine the percentage of calcium element required for the uptake of the fluoride ions in water for calcium as 39.68% for grounded Egg shells (GE). Percentage adsorption increased with increase in contact time, mass dosage and temperature for the adsorbent. The adsorption capacity was also determined which also increased with increase in contact time, temperature but decreased with increase in mass dosage at constant time of 60minutes. The pseudo first-order, pseudo second order and intraparticle diffusion kinetic models were fitted into the experimental results. The results obtained indicated that the pseudo first order and intraparticle diffusion models for the grounded Egg shells (GE) reasonably described the adsorption process very well whereas the pseudo second order model was not suitable for a calcinations temperature of 3000C and particle size of 2.12m. The adsorption isotherms were obtained from equilibrium experiment Performed at temperature of 25, 35, 45 and 550C. The result showed that Langmuir and Freundlich isotherm fitted perfectly the experimental data. However, the negative values of Gibb’s free energy indicated that adsorption was favourable and the positive enthalpy change H0 revealed that adsorption process was endothermic while the positive value of the entropy change signified increased randomness with adsorption.

Published: January 2020

The amounts of waste glass in the Bayelsa State metropolis have been growing noticeably without being reutilized increasing the danger to public well-being because of the shortage of land area. This rising challenge of waste glass in the Bayelsa State metropolis can be improved if new dumping possibilities other than landfill can be discovered. This study is geared toward the better use of waste glass material as admixture in concrete as a means to improve the concrete compressive strength. To achieve research objectives, the broken waste glasses were obtained from aluminum fabrication workshop in Amassoma. Bayelsa state Nigeria, the glasses were then milled to a fine powder smaller than 0.075mm and burnt at a controlled temperature of 200, 400, and 6000C respectively. A total of 156 concrete cubes of 150mm x 150mm x 150mm were produced employing different contents of calcined or burnt waste glass powder as admixture. The quantity of calcined waste glass powder used as admixture was varied from 0-20% at step of 5% for three different temperatures, 2000C, 4000C and 6000C. The samples were cured for 7, 14, 21 and 28days and tested in the laboratory for compressive strength. Results obtained from the study showed that the best addition dosage of calcined waste glass powder at 2000C, 4000C and 6000C are 20%, 5% and 5%. A 20% addition of Calcined waste glass powder at 2000C exhibited about 23% increase in compressive strength than the control. Base on the findings, it is recommended that the use of calcined waste glass powder as pozzolanic material should be embraced for production of concrete and can be utilized in concrete production as admixture with 5% - 20% for 2000C 4000Cand 4000C respectively.
