Microbial biotechnology for bioenergy: general overviews

Bioenergy technologies are environment-friendly, renewable, and a clean way of powering the global community. Bioenergy technology is an innovation that improves the quality of life by simply reducing water and air contamination; this also mitigates energy dependence through creation of renewable resources locally. Bioenergy sources include wind, water, geothermal, nuclear power, solar, and natural gases. The most interesting and important part of bioenergy is the environmental benefits as part of a global energy future, which are aided by microorganisms. The future of bioenergy, however, seems bright because recent global information in this field proved that more renewable energy capacity has been fixed globally than new fossil fuel and nuclear capacity combined. As the global population progressively increases, there is an everincreasing demand for clean energy. The only safe answer to this is sustainable energy, which will protect the earth from climate change and make it a good habitat for all living organisms. This chapter provides a general overview to microbial biotechnology for bioenergy, sources, and challenges of bioenergy, role of microorganisms in bioenergy generation, innovations in bioenergy, and the environmental conservation of bioenergy

Petrophysical analysis to determine the hydrocarbon prospectivity of sands in AA field, Niger Delta

Petrophysical analysis is a crucial process in the oil and gas industry. It entails the analysis and interpretation of well logs, fluid samples or core smaples to understand the behaviour of the embedded reservoirs in the subsurface. Three well logs from AA field were provided for this study, but two well data were finally loaded to the workstation due to absence of key well logs (such as gamma ray and density logs) from the third well. The quality control check of the data was done prior to the uploading of data. Delineation of lithologies and identification of hydrocarbon reservoirs were done; the identified reservoirs were correlated across the two wells; and the petrophysical evaluation (such as estimations of shale volume, porosity, permeability and water/hydrocarbon saturation) of the three pay zones (that is, Sand A, B and C) in AA field were done. The porosity of Sands A, B and C varied from 0.27 to 0.28, 0.24 to 0.30 and 0.27. The permeability of Sands A, B and C varied from 1012 to 1314 md, 884 to 1013 md and 692 to 892 md. Meanwhile, the hydrocarbon saturation for Sands A, B and C varied from 1 to 89%, 45 to 80% and 79 to 80%, respectively. It can be concluded that the order of hydrocarbon prospectivity of the reservoir sands correlated across Well AA-1 and Well AA-2 is Sand C > Sand B > Sand A

Health, Technology And Built Environment Nexus: A Systematic Literature Review

Research into health, particularly social and psychological health, is crucial. Ultimately, an in-depth understanding of social and psychological health will more than promote well-being. Technology research is indispensable, particularly concerning health and the built environment, given the need to create holistic and supportive frameworks for well-being. Moreover, because literature reviews establish the foundation for academic inquiries, they provide valuable overviews for foresight into grey research areas, particularly multi-disciplinary research like health technology and the built environment. Hence, this study aims to discover the existing themes on health, technology, and built-environment nexus subjects while revealing the grey areas and suggesting proactive areas for future research. The objectives drove this aim to: 1. investigate the implications of technology for the social and psychological dimensions of health; 2. uncover the likelihood of a nexus between health, technology, and the built environment; and 3. highlight new research perspectives for the concluding seven years of the SDGs (2024–2030). The review results highlighted ten themes around which a nexus exists between health, technology, and the built environment; they also pointed out new research perspectives for the next seven years (up to 2023)

Statistical evaluation of effect of anthropometric measurements on adolescent idiopathic scoliosis

Scoliosis is a deformity in which there is sideways curvature to the spine. Curves are often S shaped or C shaped. Most common type is the idiopathic type which occurs in 10-12 years of age and early teens, females are more affected than males while the body is growing fast and the curve is commonly to the right side of the body. It however affect all ages of about 3% of general population. This study was set out to evaluate statistically, the effect of age, gender and anthropometric measurements (such as height, weight and body mass index) to the curve formed using 51 patients from Lagos State University Teaching Hospital, Ikeja. It was discovered from the analysis that the ailment is common among females than males. The result also shows that the curve is most common to right hand side. The test of hypothesis conducted reveals that the anthropometric measurements of height, weight and body mass index though positively correlated with but do not have significant effect on the Adolescent Idiopathic Scoliosis curve

Setting Time and Workability of Geopolymerized Fly Ash-Phosphogypsum Paste and Mortar

Geopolymer is no longer viewed as a concept for a greener society but rather as a pragmatic solution for reducing CO2 emissions in the construction industry. It is commonly produced using industrial waste materials such as fly ash (FA) and phosphogypsum (PG). Globally, FA has an estimated annual production of around 1 billion tonnes and that of phosphogypsum is around 300 million tonnes, of which utilization stands at 50% and 15% of the total generated, respectively [1]. Geopolymers have been extensively studied as an alternative to ordinary Portland Cement (OPC) [2], [3] but to date, no study has been done to investigate the setting time and workability of geopolymerized fly ash-phosphogypsum paste and mortar. This research investigates the setting time and workability of geopolymerized fly ash-phosphogypsum paste (GPP) and mortar (GPM) using a Vicat needle procedure per ASTM C191 and the flow table test per ASTM C1437, respectively. The materials used were PG, Class F FA, silica sand, NaOH pellets of 99% purity, and Na2SiO3 solution of the composition Na2O = 8.3%, SiO2 = 27.7%, H2O = 64%, and Ms (SiO2/Na2O) = 3.34. The dissolution of NaOH pellets in water is an exothermic process [4] therefore the prepared NaOH solution was kept in a sealed glass bottle for 24 hours at room temperature to allow sufficient cooling before mixing with the Na2SiO3 solution. The specimens were prepared at 10M NaOH + Na2SiO3 Ms of 3.34, Na2SiO3/ NaOH ratio of 1.5, Alkaline Liquid/Precursor ratio of 0.4, Binder/Aggregate ratio of 1.0, and varying PG at 10 wt% increments. As per ASTM C305 for mixing pastes and mortars, the preparation of the specimens started with dry mixing the FA with PG in a conventional pan mixer for 3 minutes, followed by the gradual addition of alkaline solution and wet mixing for 5 minutes. Soon after wet mixing, the manufactured paste and mortar were tested for setting time and workability. It was found that an increase in the PG wt% led to a decrease and/or acceleration in the initial setting time (INSET) and final setting time (FINSET) attributed to the rapid dissolution of Ca2+ in low alkaline concentrations outnumbering that of Al3+ and Si4+ and thus forming ettringite and C-A-S-H gel that facilitates hardening shortening the setting time [5], [6]. The INSET of GPP decreased from 37 min (at 10wt% PG) to 27 min (at 30 wt% PG) while the FINSET of GPP decreased from 155 min (at 10wt% PG) to 125 min (at 30 wt% PG). The INSET of GPM decreased from 29 min (at 10wt% PG) to 23 min (at 30 wt% PG) while the FINSET of GPM decreased from 142 min (at 10wt% PG) to 113 min (at 30 wt% PG). Furthermore, the workability of GPP and GPM decreased with an increase in PG wt% attributed to faster hydration activity, accelerated setting, and increased viscosity. The workability of GPP decreased from 176 mm (at 10 wt% PG) to 138 mm (at 30 wt% PG) while that of GPM decreased from 137 mm (at 10 wt% PG) to 112 mm (at 30 wt% PG). The development of GPP and GPM offers a sustainable circularity construction solution to minimize OPC usage and prevent the disposal of FA and PG in landfills. Future research should investigate the mechanical properties of GPP and GPM

Prospect o f Recovering Bio -fertilizer by Anaerobic Co - digesting Cow Manure, Palm Oil Sludge, and Cassava Peels

Improper crop and animal waste management and disposal are now widely recognized as environmentally harmful practices. When crop waste is placed in landfills, greenhouse gases (GHG) like carbon dioxide (CO2) and methane (CH4) are created. In order to create the digestate for usage as bio-fertilizer from agricultural waste employing cow dung as an inoculum for 30 days of the hydraulic retention period, a 225L Polyethylene (PE) anaerobic digester was used in this study. Cassava peels, palm oil sludge, cow dung, and water were mixed in a 1:1:2:5.3 ratio. About 1.3 kilogram of crushed eggshells was added to keep the pH level within the range recommended for the anaerobic digestion process. In order to maintain mesophilic conditions during anaerobic co-digestion for enhanced organic fertilizer output, the greenhouse was used to regulate temperature. Since microbial populations flourish in friendly environments, the pH averaged 6.0 and the average slurry temperature was 34.76 oC during digestion. After 30 days of hydraulic retention time, a laboratory-scale elemental analysis of the digestate showed that the contents of nitrogen (N), phosphorus (P), and potassium (K) increased by 95%, 75%, and 93.8%, respectively. The anaerobic co-digestion of animal and agricultural waste has created digestate rich in NPK nutrients, but more research should be conducted to see whether the biofertilizer’s efficacy on fast-growing crops can be determined by measuring the number of harvests and height of the plants
