Abstract:

Chemical characterization of Portland limestone cement products collected across the nine existing cement manufacturing plants in Nigeria was conducted using Energy Dispersive X-ray Fluorescence Spectrometer (EDXRF) with the aim of determining conformity with global and local standards and investigating likely variation in quality resulting from differences in the sources of major raw materials, especially limestone used in production. The cement samples are composed essentially of CaO, SiO2, Al2O3, Fe2O3, MgO, Na2O, K2O and SO3 while P2O5, MnO and TiO2 were present in trace amount. In addition to oxide compositions, the mineralogical components: Alite (C3S), Belite (C2S), Celite (C3A), and Ferrite (C4AF), and other cement quality control variables such as Lime Saturation Factor, Silica Modulus and Alumina Modulus of all the nine cement samples analyzed in this study are in agreement with the specifications for Portland limestone cement published by the Standard Organisation of Nigeria (SON), the American Society for Testing and Materials (ASTM), and the British Standards Institution (BSI). The nine cement products also have their compositions in close proportion indicating none of the products is superior in quality irrespective of manufacturer or production site, a common misconception in the Nigerian cement market.

Abstract:

The cement manufacturing industry has played a fundamental role in global economic development, but its production is a major facilitator to anthropogenic CO2 release and solid waste generation. Nigeria has the largest cement industry in West Africa, with an aggregate capacity of 58.9 million metric tonnes (MMT) per year. The Ministry for Mines and Steel Development asserts that the nation possesses total limestone deposits of around 2.3 trillion MT with 568 MMT standing as established reserves and 11 MMT used. Cement industries are largely responsible for releasing air pollutants and effluents into water bodies with apparent water quality deterioration over the years. Air pollution from lime and cement-producing plants is seen as a severe instigator of occupational health hazards and work-related life threats, negatively affecting crop yields, buildings, and persons residing in the vicinity of these industries. World Bank observed in 2015 that 94% of the Nigerian populace is susceptible to air pollutants that surpass WHO guidelines. In 2017, World Bank further reported that 49,100 premature deaths emanated from atmospheric PM2.5, with children beneath age 5 having the greatest vulnerability owing to lower respiratory infections, thereby representing approximately 60% of overall PM2.5-induced deaths. Cement manufacturing involves the significant production of SO2, NOx, and CO connected to adverse health effects on humans. Sensitive populations such as infants, the aged, and persons having underlying respiratory ailments like asthmatics, emphysema, or bronchitis are seen to be most affected. Consequently, in addressing this challenge, growing interests in enacting carbon capture, usage, and storage in the cement industry is expected to alleviate the negative environmental impact of cement production. Still, no carbon capture technology is yet to achieve commercialization in the cement industry. Nonetheless, huge advancement has been made in recent years with the advent of vital research in sorption-enhanced water gas shift, underground gasification combined cycle, ammonium hydroxide solution, and the microbial-induced synthesis of calcite for CO2 capture and storage, all considered sustainable and feasible in cement production.

Abstract:

The recent outburst of novel Coronavirus disease (COVID-19), now a global pandemic highlights an urgent need for therapeutics targeting ‘severe acute respiratory syndrome’ (SARS-CoV-2). In Nigeria, infection cases are on daily rise with death rate of ~3 %. Therefore, slowing the spread of the virus will significantly reduce the strain on the healthcare system and governments. Here, we presented local medicinal plants cultivated in Nigeria as possible therapeutic approaches, exclusively targeting SARS-CoV-2 and its pathways. The study focused on some plants containing bioactive compounds that showed promising results against previous coronaviruses. Potential plants identified include Zingiber officinale, Allium cepa, Allium sativum, echinacea, euphorbia hirta, Garcenea kola, Curcuma longa, Aleo vera and olea europaea. Although inhibition of viral replication is seen as the possible mechanism for antiviral activity of most of the natural compounds, recent research has shown that some natural compounds can interact with major viral proteins associated with virulence. Thereby, showing they could be a valuable tool for possible inhibition, management and treatment of SARS-CoV-2. However, further research is required to investigate and validate their potential use as anti-SARS-CoV-2.

Abstract:

A case study was conducted in Beijing to identify municipal sewage sludge (SS) management systems appropriate for a sound material-cycle society. The environmental and economic impacts of four realistic SS-handling scenarios were investigated: stabilization by thermal drying, increased inclusion of SS in cement manufacture, and using either dried or carbonized SS as substitute fuel for coal-fired power generation plants. The results showed that the current sludge management system had the lowest operating cost but higher greenhouse gas (GHG) emissions and a low recycling rate. The case with the use of carbonized SS reused in coal-fired power plants had higher energy consumption and almost the same GHG emissions as the current system. On the other hand, the case including more SS in cement manufacture had the same level of energy consumption with much lower GHG emissions. The case with the use of dried SS in coal-fired power plants also resulted in lower energy consumption and lower GHG emissions than at present. Furthermore, sensitivity analysis showed that drying SS with surplus heat from cement plants used less energy and emitted less GHG compared to the other two drying methods.

Abstract:

Purpose Recent developments in the electricity generation sector of Nigeria necessitated the re-assessment of its contribution to air emission level in the country as information provided by previous inventory is nearly out-of-date. The purpose of this paper is to quantify the carbon dioxide (CO2) emissions generated from existing thermal power plants in the country. Design/methodology/approach Thermal power plants in Nigeria and their installed capacities were identified, and estimation of CO2 emission from each of the plants was carried out using the emission factor method. In addition to the direct emissions generated through the combustion operation of the power plants, indirect emissions resulting from upstream activities such as extraction, production, and transportation of fuels consumed by the thermal power plant was determined using the same method. Findings In total, 40 thermal power plants are currently operational in Nigeria. Additional 18 thermal plants are at different stages of completion. The operational thermal plants have average generation output of 40 percent of their installed capacity and produce 87.3 million metric tonne (mmt)/annum CO2 emissions. In total, 66.9 percent of the estimated emissions are direct emissions, i.e. fuel combustion emissions; the rest are indirect emissions. Additional 67.9 mmt was estimated as expected overall emissions from the thermal power plants under construction. Considering the global warming potential of CO2, proactive measures must be taken to regulate its emissions from the country’s thermal power plants. Originality/value This paper bridged the information gap existing in the emission inventory from the Nigeria electricity sector by providing up-to-date data on the contribution of the sector to greenhouse gas emission level in the country.

Abstract:

Purpose The demand of cement in India is expected to increase rapidly as the government has been giving immense boost to various housing facilities, infrastructure projects, road networks and railway corridors. One of the ways to meet this rise in the demand of cement is to increase the capacity utilization of the existing cement plants by improving their availability. The availability of a cement plant can be improved by avoiding failures and reducing maintenance time through reliability, availability and maintainability (RAM) analysis of its subsystems. The paper aims to discuss this issue. Design/methodology/approach The data related to time between failure (TBF) and time to repair (TTR) of all the critical subsystems of a cement plant were collected over a period of two years for carrying out RAM analysis. Trend test and serial correlation test were performed on TBF and TTR data to verify whether these data are independent and identically distributed or not. Afterwards, the authors use EasyFit 5.6 professional software to find best-fit distribution of TBF and TTR data and their parameters. The effectiveness of a preventive maintenance policy was evaluated by simulating the real and proposed systems. Findings The results of the analysis show that the raw mill and the coal mill are critical subsystems of a cement plant from a reliability point of view, whereas the kiln is a critical subsystem from an availability point of view. The analysis shows that the repair time of the cement mill should be reduced for improving the availability of the cement plant. The RAM analysis showed that the capacity of the case study company is 17 percent underutilized due to maintenance-related problems and 15 percent underutilized because of management-related problems. Practical implications The study exhibits the usage of RAM analysis in deciding preventive maintenance programs of several cement plant subsystems. Thus, it would serve as a reference for reliability and maintenance managers in deciding maintenance strategies of cement plants as well as in improving their capacity utilization. Originality/value The study exhibits the usage of RAM analysis in deciding preventive maintenance programs of several cement plant subsystems. Even more, using a simulation study, the authors show that preventive maintenance of the cement plant beyond a certain level can be disadvantageous as it leads to an increase in downtime and decrease in availability.

Abstract:

Abstract Carbon dioxide fluxes between ecosystems of the Earth are presented. It was shown that intensifying its absorption of terrestrial ecosystems by 3.2% would prove sufficient to neutralize carbon dioxide emissions from the combustion of fossil fuels and cement production. It was shown that Polish forests absorb 84.6 million tons of CO2/year, that is 26% of emissions from fossil fuel combustion and cement production, while agricultural crops absorb 103 million tons of CO2/year. Total carbon dioxide sequestration by forests and agricultural crops amounts to 187.5 million tons of CO2/year, which is tantamount to 59% of emissions from fossil fuel combustion and cement production. Forestation of marginal soils would further increase carbon dioxide absorption in Poland by 20.6 million tons of CO2/year. Moreover, if plants were sown in order to produce green manure - instead of leaving soil fallow - sequestration could still be boosted by another 6.2 million tons of CO2/year.

Abstract:

Aquatic plants are important in freshwater ecosystems. They provide food, shelter, spawning and nursery grounds for fish. They are usually found at the littoral parts of freshwater ecosystems. The abundance, distribution and diversity of aquatic plant of Ikere-gorge, Iseyin, Nigeria were examined between January 2017 and December 2018. There are twelve fishing villages in Ikere-gorge and four villages were randomly selected. Aquatic plants were sampled and collected with the help of hired fishermen. The collected aquatic plant samples were identified at the Forest Herbarium of the Forestry Research Institute of Nigeria with appropriate keys. This work identified 13 families and 23 species of aquatic plants. Cyperaceae family recorded the highest (4) number of individual species while Salvinia molesta had the highest abundance in all the sampling sites. The ecological classification of the aquatic plants showed that 14 species are emergent; 7 species floating and 3 species submerged. Site C had the most abundance (9220) of aquatic plants, followed by site D (8490), site B (8130) and site A (7940). The gamma (γ) and beta (β) diversities were 23 and 0.01 respectively. The alpha (α) diversity included Dominance (0.08), Simpson (0.92) and Shannon-Wiener (2.72) respectively. These results show that Salvinia molesta and Najas guadalupensis are the most and least abundant aquatic plants in Ikere-gorge respectively; which may be due to their ecological status. Moreover, management of aquatic plants is an integral part of fisheries management for sustainable fisheries. Therefore, their management is essential for the maintenance of aquatic biodiversity.

Abstract:

Objectives: The health conditions of women are broad, and range from pregnancy, gynaecological conditions to overall health/wellness. Ethnomedicinal investigation on plants used in the management of women-related health disorders was conducted in Bode herbal market, Ibadan, Southwestern Nigeria to further emphasize the role of herbal medicine in reproductive health. Methodology and Results: Ten herb sellers (all females; age range, 35 – 57; mean, 45.80; SD, 7.41) were interviewed in the local language (Yoruba) and their responses recorded. Recipes used in the management of arthritis, fibroid (uterine and menopausal), and obesity/overweight were documented. Thirty (38) plant species belonging to 24 plant families are profiled. The family Fabaceae had the highest number of species (n=7) while stem bark was the most frequently used (37%) plant part. Methods of preparations were mainly decoction and steeping of botanicals in alcohol. Administration includes taking one tot/half-a-glass cup, 2 (morning and night) to 3 times daily. Conclusion and Application of Findings: This study documents and further emphasizes the role of medicinal plants in female reproductive health. Although some of the plants reported here have been cited for the management of diseases such as skin infections and malaria/yellow fever, published reports on their use for women-related health disorders are limited. This research finds application in reproductive disorders in women and alternative approach to health care systems. These plants are presented for experimentation and scientific validation. Efforts should be made to conserve these plants, especially those that show promising bioactivity. Key words: Women, Arthritis, Fibroid, Obesity, Medicinal plant, Nigeria

Abstract:

Purpose – Cement production has advanced greatly in the last few decades. The traditional fuels used in traditional kilns include coal, oil, petroleum coke, and natural gas. Energy costs and environmental concerns have encouraged cement companies worldwide to evaluate to what extent conventional fuels can be replaced by waste materials, such as waste oils, mixtures of non-recycled plastics and paper, used tires, biomass wastes, and even wastewater sludge. The paper aims to discuss these issues. Design/methodology/approach – The work is based on literature review. Findings – The clinker firing process is well suited for various alternative fuels (AF); the goal is to optimize process control and alternative fuel consumption while maintaining clinker product quality. The potential is enormous since the global cement industry produces about 3.5 billion tons that consume nearly 350 million tons of coal-equivalent fossil and AF. This study has shown that several cement plants have replaced part of the fossil fuel used by AF, such waste recovered fuels. Many years of industrial experience have shown that the use of wastes as AF by cement plants is both ecologically and economically justified. Originality/value – The substitution of fossil fuels by AF in the production of cement clinker is of great importance both for cement producers and for society because it conserves fossil fuel reserves and, in the case of biogenic wastes, reduces greenhouse gas emissions. In addition, the use of AF can help to reduce the costs of cement production.

Abstract:

The samples in the study of Ashaka cement environs were collected on both mineralized and unmineralized ground. These were analyzed to determine the amounts of the elements absorbed by the plants in the area under study using analytical methods (IR, AAS). The observations and prediction of the results show that secondary carbonate minerals, especially those of the common base metals such as magnesium, lead and zinc may be found in Gombe-Bauchi ore bodies include associate minerals. The associate minerals that may be found are hydrozincite, Zn5(CO3)2(OH)6, hydrocerussite, Pb3 (CO3)2 (OH)2 and the very rare mineral plumbonacrite, PbOO(OH)6(CO3)2, Dypingite, Mg5(CO3)4(OH)2.5H2O etc. This is in accordance with the statistical interpretation of the results. The standard deviation were identified as action line , which is equivalent to 59.16 and 49.84 , while two standard error as warning lines, that is resulting in 58.91 . The expectation of these minerals in abundance depends on the ratio of a(Ca2+)/a(Mg2+), a(Ca2+)/a(Zn2+) and a(Ca2+)/a(Pb2+). The technological importances of these associate and very rare minerals are discussed.

Abstract:

The principal component analysis (PCA) is applied in this paper, since the existing power consumption prediction models of cement manufacturing influenced by many factors are quite complex and have low accuracy. In this way, four new key factors affecting the power consumption of cement manufacturing are obtained instead of the eleven original ones, with the complexity of the computing model simplified. Built upon this is the power consumption prediction model of cement manufacturing based on an improved multiple non-linear regression algorithm. Then the efficiency of the model, obviously improved the forecasting precision, is verified in Pingyi Zhonglian Cement Plant. In other words, a theoretical basis for cement plants power consumption forecasting management is provided in this paper.

Abstract:

AbstractIn this study, the CERES-Maize model was calibrated and evaluated using data from 60 farmers’ fields across Sudan (SS) and Northern Guinea (NGS) Savannas of Nigeria in 2016 and 2017 rainy seasons. The trials consisted of 10 maize varieties sown at three different sowing densities (2.6, 5.3, and 6.6 plants m−2) across farmers’ field with contrasting agronomic and nutrient management histories. Model predictions in both years and locations were close to observed data for both calibration and evaluation exercises as evidenced by low normalized root mean square error (RMSE) (≤15%), high modified d-index (> 0.6), and high model efficiency (>0.45) values for the phenology, growth, and yield data across all varieties and agro-ecologies. In both years and locations and for both calibration and evaluation exercises, very good agreements were found between observed and model-simulated grain yields, number of days to physiological maturity, above-ground biomass, and harvest index. Two separate scenario analyses were conducted using the long-term (26 years) weather records for Bunkure (representing the SS) and Zaria (representing the NGS). The early and extra-early varieties were used in the SS while the intermediate and late varieties were used in the NGS. The result of the scenario analyses showed that early and extra-early varieties grown in the SS responds to increased sowing density up to 8.8 plants m−2 when the recommended rate of N fertilizers (90 kg N ha−1) was applied. In the NGS, yield responses were observed up to a density of 6.6 plants m−2 with the application of 120 kg N ha−1 for the intermediate and late varieties. The highest mean monetary returns to land (US$1336.1 ha−1) were simulated for scenarios with 8.8 plants m−2 and 90 kg N ha−1, while the highest return to labor (US$957.7 ha−1) was simulated for scenarios with 6.6 plants m−2 and 90 Kg N ha−1 in the SS. In the NGS, monetary return per hectare was highest with a planting density of 6.6 plants m−2 with the application of 120 kg N, while the return to labor was highest for sowing density of 5.3 plants m−2 at the same N fertilizer application rates. The results of the long-term simulations predicted increases in yield and economic returns to land and labor by increasing sowing densities in the maize belts of Nigeria without applying N fertilizers above the recommended rates.

Abstract:

Introduction. Currently, the issue related to the utilization of sludge from water treatment plants (WTP), including in the production of building materials, is quite urgent. In this regard, the purpose of the study was to obtain new compositions of raw mixtures to manufacture building products using WTP sludge as a raw component. Methods and Materials. The paper presents the characteristics of the used binders and WTP sludge, and outlines some experimental methods. Portland cement and gypsum binder were used in non-fired materials, while clay was used in fired materials as binders. Strength properties, air and fire shrinkage were determined using standard methods. Results. Based on the analysis of the results obtained during the tests, we established that it is inexpedient to use WTP sludge without special treatment in combination with Portland cement as a binder in the production of non-fired building materials. We also developed preliminary compositions of gypsum concrete with the use of WTP sludge. Conclusion. WTP sludge can be most effectively used in the production of fired ceramic materials. However, its practical use requires more detailed research aimed at optimizing compositions and designing specific processes, including, if necessary, those related to sludge treatment.

Abstract:

Background: Rural and urban people in Nigeria made use of medicinal plants as their curative measures, based on their ancient belief that propounded the authenticity of these plants in treating ailments. Materials and methods: Data were collected through semi-structured questionnaires across the study area (3senatorial districts),The collected plant species were authenticated and given voucher numbers, and the demographic data was subjected to Chi-square (x2) comparisons using SPSS version 22. Results: The major family among the surveyed plants, were Fabaceae (dominant), followed by Anacardiaceae and Combretaceae. Moreover, out of 97 respondents, 81 were male (83.5%) and 16 were female (16.5%). It was observed that respondents that were 41-50 years were many into practice ( p = 0.13. The majority of the respondents as compared using chi-square across the parameters, were illiterates (p = 0.06), and very few had a formal training or exposed to workshops (p = 0.02), while the majority inherited and utilized herbal medicine practice as their main sources of income (p = 0.04). The fidelity levels ranged as follows: For diarrhea (18.5% -100%), dysentery (11.11- 45%), pile (11.11 – 50%) and, ulcer covered 9.1% -100%. The ailments were in the range of 0.69 – 0.75 factors of informant consensus. Plant species with RFC values of 0.34, 0.27 and 0.21 as well as those with 0.1, were regarded to have the highest RFC values. Conclusion: Information collected were mainly on cases of gastrointestinal ailments and first of its kind on the use of medicinal plants in Yobe State, Nigeria.

Abstract:

Objectives: A comprehensive survey with the aim of documenting traditional medicinal practices was carried out in targeted areas of Ibadan, Nigeria in order to inventory plants used by traditional healers in the area for the management of diabetes. Materials and Methods: Open-ended informal interviews were administered during series of repeated visits to the respondents consisting majorly the traditional medical practitioners (TMPs) and herb sellers. Some traditional healers who know and use medicinal plants for treating diabetes mellitus were interviewed. The inventory contains scientifi c, vernacular, common names of the plants used and methods of preparation. Results: Twenty seven plants commonly used by traditional healers in the region were identifi ed. These plants were found to be very important and useful in the treatment of diabetes based on their frequency of occurrence in the recipes obtained. Herbal remedies were either prepared from dried or freshly collected plants while traditional solvent of choice included water, lime, local gin and aqueous extract from fermented maize. Decoction and pulverization were the main methods of preparation while mode of administration varies within 1 to 3 times daily. Survey revealed that leaves form the major part of plants for herbal preparations. Residents in the study area fi nd traditional medicine cheaper as compared to orthodox medicine. Conclusion: This review focuses on the various plants that have been reported to be effective in the treatment of diabetes. The survey shows that plants from the Rubiaceae, Labiataceae, Meliaceae, Hypoxidaceae and Cucurbitaceae families are commonly used by traditional healers in Ibadan for the treatment of diabetes mellitus.
