The methodology used by the researcher is the ' lottery system' of the simple random sampling system after the researcher had distributed 120 questionnaires and was able to get 93 questionnaires back. Also, the frequency distribution tables, bar charts, relative importance index as well as Chi square test were used for the analysis of the data got. According to the summary of findings, poor waste disposal and traffic congestions are the major causes of neighborhood degeneration in the area. Finally, the researcher gave suitable recommendations and conclusions. It should be noted that this research is subject to further studies.
Natural and anthropogenic biomarkers in recent dated sediment cores from Refome Lake, SE Nigeria: environmental implications
(Environ Earth Sci, 2016) Oyo-Ita, Orok Esu; Oyo-Ita, Inyang Okon; Sam, Edidiong Sunday; Ikip, Ekpo Offem; Ugim, Ugim Samuel
Natural and anthropogenic biomarkers characteristics of two recent sediment cores collected toward the shoreline and center of Refome Lake (RS and RC; 30 cm long), southeastern Nigeria, were investigated in order to reconstruct past environmental conditions and asses humans-induced changes on the local ecosystem over the last century. Results from sediment bulk properties such as total organic carbon (TOC; 0.12–0.54%; mean— 0.26 ± 0.9%), total nitrogen (TN; 0.01–0.05%; mean— 0.03 ± 0.7%) and total inorganic carbon (TIC; 0.03–0.37%; mean—0.14 ± 1.0%) contents as well as TOC/TN (5–25; mean—11.55 ± 1.4) suggested slightly higher contribution from allochthonous over autochthonous organic matter (OM), lowered by low primary production and the characteristic Niger Delta sheltered basin morphology predominated by sandy lithology. Evaluation of molecular proxies such as carbon preference index (CPI(C24–C35); 1.23–1.74: mean—1.58 ± 0.4), carbon maxima (Cmax—17, 19, 26, 27, 29), long-chain/short-chain hydrocarbons (LHC/SH-C; 0.77–2.25, mean—1.52 ± 0.3) and Paq, (0.21–0.61, mean–0.45 ± 0.3) as well as C29/C27 (0.89–2.67; mean—1.53 ± 0.2) indicated an admixture slightly predominated by microbial OM (algae/bacteria) in the most recent top layer (RC1, 0–5 cm) of RC core and slightly more enhanced terrestrially derived OM in the middle layer (RS4, 15–20 cm) of RS core. The later sediment layer deposited at ca. 1947–1964 coincided with the period of greater wash-in of land-derived OM (associated with tree logging/forest clearing for foot path extension and farmland preparation authorized by the European settlers) occasioned by intense rainfall. The occurrence of gammacerane and 18a-oleanane in low levels in the lower and upper layers revealed trace contamination by petroleum hydrocarbons imported into the Nigerian economy prior to independence in 1960 and utilization of Niger Delta oil after 1960 following departure of the colonial masters (the British), respectively.
Source Characterization and Historical Trend of Sedimentary PAHs from Refome Lake, South–South Nigeria
(Aquat Geochem, 2017) Oyo-Ita, Inyang O.; Oyo-Ita, Orok E.; Ikip, Ekpo O.; Sam, Edidiong S.; Ugim, Ugim S.
Polycyclic aromatic hydrocarbons (PAHs) released from diverse sources passing through water column carry information into the sediment where they can be used to assess the environmental status of an ecosystem over specified geologic time frame. The vertical distributions of PAHs in two recent sediment cores (RS and RC, 30 cm long) from Refome Lake, South–South Nigeria,were investigated using gas chromatography–mass spectrometry in order to evaluate their sources and historical trends of deposition over the last ca. century. The total PAHs (TPAHs—sum of parent and retene) concentrations ranged from 66.99 ng/g dry weight (dw) at the middle layer ofRCcore (RC3 10–15 cm) to 182.24 ng/gdwat the near-bottomlayer of RS core (RS5 20–25 cm) with amean of 102.21 ± 24.32 ng/g. The elevated TPAH level at the near-bottom layer of the RS core, corresponding to geologic time-frame ca. 1930–1947, coincided with the period of inhabitation of the European settlers along the lake’s catchments when utilization of coal and/or coal products for domestic/recreational activity was at its peak. A decline in TPAH levels up-cores thereafter reflected the periods of gradual evacuation of inhabitants of the lake area hinterland following the departure of theWhite after the Nigerian independence in 1960. Evaluation of PAH category according to ring size coupled with data from specific molecular ratios revealed inputs dominated by wood/coal combustion with a moderate contribution from petrochemical/liquid fossil fuel exhaust emissions and a minor diagenetic sources. Principal component analysis result not only distinctively separated RS fromRCcore samples but also revealed that the RS samples weremore impacted by wood/coal combustion emissions than the RC, while liquid fossil fuel exhaust emission dominated the RC over the RS samples. Although short-range eolian transport did play a role in the delivery of PAHs to the lake, localization of source contamination was more important.
Determination Of Nutritional Potential Of Cymbopogon Citratus (D.C.) Staph By Atomic Absorption Spectroscopy And Its Health Benefits
(International Journal of Innovative Research and Advanced Studies (IJIRAS) Volume 5 Issue 3,, 2018) Umoh, Emmanuel Michael; Sam, Edidiong Sunday; Udoh, I. I.
Lemon grass (Cymbopogon citratus) was processed for analyses. They were sorted and chopped into bits. They were sundried for 12hrs, oven dried for 24hrs at 60oC and pulverized. Digestion was carried out according to AOAC 2000 and analysed for P, Mg, K, Na, Se, B, Co, Fe, Zn, Mn, Cu and Ca contents using Unicam 939/959 Atomic Absorption Spectrophotometer. Out of these twelve “botanical based minerals”, the most abundant was potassium followed by magnesium, phosphorus and calcium the least being boron. Most nutritional problems in Nigeria experienced by the vulnerable groups - the children and the elderly are due to mineral deficiencies in unwholesome or processed foods. Minerals usually obtained from synthetic mineral supplements are inadequate for the rural population due to high cost of procurement and at times adulteration. Most of them are toxic to susceptible individuals. Lemon grass is very effective in „Ajurvedic‟ medicine because of the “botanical based minerals” and bioactive compounds therefore taken in adequate quantities will help in the improvement of general health.
Effects of Sustainable Lighting Strategies on Users’ Patronage of Visual Art Centres in Lagos, Nigeria
(Covenant Journal in Research & Built Environment 8(2), 2020) Ekhaese, Eghosa N.; Omoijiade, Joshua
This paper set out to identify the relationship between the sustainable design of lighting within a visual art centre and its effect on the patronage of users in the study area. The study employed a mixed methods approach using case study analysis and questionnaires to collect data. In the course of research two art galleries namely; Nike Art gallery and Hour glass art gallery were compared with the prior deemed to be more sustainable with its integration of lighting; and the results of the amount of patronage compared to determine if the effect of sustainable lighting strategies on user patronage was indeed significant if existent at all. The study at the onset, hypothesised that an art centre integrating more sustainable lighting strategies can be expected to demand more patronage from users as the users are intuitively attracted to the benefits of such a design. Upon completion of the paper it was concluded that the levels of patronage observed did not vary greatly between either gallery. The study recommends further studies on a larger scale to arrive at more generalisable conclusions
The Recycling of Sawdust Waste into Particleboard Using Starch- Based Modified Adhesive
(Communication in Physical Sciences, 6(1), 2020) Umoh, Emmanuel Michael; Sam, Edidiong Sunday
The challenges associated with the management of wastes from the cassava processing and timber industries necessitated an investigation into the possibility of implementing recycling approach to produced particle board from these wastes. Particleboards were produced from wood saw dust using various compositions of modified starch adhesives. The product obtained were evaluated for density, moisture content, hardness, flexural strength, water absorption and thickness swelling. The results obtained indicated that the density ranged from 753 to 798 kg/m3, moisture content ranged from 14.87 to 16.67 %, hardness ranged from 9.02 to 9.31 N/nm2, flexural strength ranged from 1.31 to 1.45 MPa, water absorption capacity at 24 h ranged from 1.06 to 9.31 %, thickness swelling ranged from 4.55 to 4.78%. The products were in conformity with IS 3087 (2005) and ANSI A 208.1 (1993) standards and could go for medium density particleboard.
VAPOUR GENERATION CHEMILUMINESCENCE DETECTION SYSTEM FOR DETERMINATION OF DIMETHYLSULPHONIOPROPIONATE AND DIMETHYLSULPHIDE IN TROPICAL SEAWATER
(Rasayan J. Chem., 13(1), 44-50(2020), 2020) Adedapo, A. E.; Benson, N. U.; Williams, A. B.,; Toda, K.
The vapour generation – chemiluminescence (VG-CL) detection system that was designed for this research was used for the measurement of dimethylsulphide (DMS) and its precursor dimethylsulphoniopropionate (DMSP). The present study attempted the development of a highly sensitive, portable and cost-effective detection system based on vapour generation and chemiluminescence for a pilot assessment and determination of DMSP and DMS concentrations in the Gulf of Guinea. The Elegushi Beach and Nigerian Institute of Oceanography and Marine Research (NIOMR) which are parts of the Atlantic Ocean were chosen as designated locations for this study. The average concentrations of DMSP and DMS in the surface seawater at the two locations ranged from 12.4 ± 0.2 to 26.5 ± 0.5 nM, 2.1± 0.0 to 40.9 ± 1.6 nM and 9.7 ± 0.4 to 44.9 ± 0.2 nM, 0 to 35.6 ± 2.3 nM, respectively. This study serves as a baseline measurement of the concentrations of DMS and DMSP in the tropical Atlantic Ocean (Lagos).
Application of Nanochitosan in the Detection of Pesticide Residues and Degradation
(2020) Yakubu, Japhet Gaius; Oyewole, Oluwafemi Adebayo; Ilyasu, Ummulkhair Salamah; Ayanda, Opeyemi Isaac; Adetunji, Charles Oluwaseun
Chemicals called pesticides are used to manage pests like weeds, rodents, and insects. They are commonly used in agriculture to safeguard animals and crops from pests and illnesses. The usage of pesticides, however, can potentially have detrimental effects on the environment and public health. Pesticides can harm non-target creatures and contaminate the soil, water, and air. In addition, exposure to pesticides can result in a variety of medical issues in people, such as cancer, neurological conditions, and reproductive issues. Chitosan is a natural polymer formed from crab shells. Nanochitosan is chitosan in a nanoscale form. It has several distinctive qualities that make it a potential material for a variety of applications, including the detection and degradation of pesticides, such as large surface area, biocompatibility, and non-toxicity. There are numerous ways to detect pesticides using nanochitosan. Utilizing sensors made of nanochitosan is one typical strategy. Usually, nanochitosan is immobilized onto a substrate, like a gold electrode, or nanochitosan-based colorimetric assays are used to create these sensors. Because there is currently no environmentally benign method of pesticide remediation, scientists have looked for other ways to prevent pesticides from having a negative impact on the ecosystem. In order to degrade pesticides, nanochitosan has been used in a variety of ways. These include the usage of nanochitosan-based adsorbents, which are typically created by adding a functional group with a strong affinity for pesticides to nanochitosan. The pesticide is subsequently removed from the environment by the functional group after it attaches to it. Because nanochitosan can be impacted by environmental factors including pH and temperature, there are restrictions on its usage for bioremediation. Nanochitosan provides a number of benefits over other materials used for the detection and degradation of pesticides, notwithstanding its limits. As a result, it may be investigated to reduce the effects of pesticides on the environment.

(International Conference on Energy and Sustainable Environment (IOP Publishing), 2021) Ekhaese, Eghosa N.; Evbuoma, I. K.; Adejuwon, G. A.; Odukoya, J. A.
Homelessness is a social, psychological, environmental, economical, family, and individual condition that describes the homeless. The object of this paper is identify the homelessness factors and its psychological wellbeing concerns on the urban residents in Nigeria. The study employed qualitative method using observation schedule, photographs, tables, charts and interview guide to collect data among homeless people in cities across the six geopolitical zones of Nigerian. Findings indicate that homelessness are in categories, and are characterized by factors such as psychological, anthropological, ecological, economic, cultural, sociological and religious. The psychological wellbeing implications of homelessness among the homeless population in Nigerian urban cities were highlighted. The result of study showed that homelessness factors in Nigerian cities can predict the severe health and psychological wellbeing consequences of urban residents. It was concluded that the concerns of homelessness on the psychological wellbeing and general health of the homeless in Nigerian cities require urgent attention.
Promoting Green Urbanism in Nigerian Purlieus as Therapy for Psychological Wellbeing/Health
(International Conference on Energy and Sustainable Environment, 2021) Ekhaese, Eghosa N.; Adejuwon, G. A.; Evbuoma, I. K.
Green urbanism highlight on reducing unforeseen dangers to human wellbeing through exposure to various environmental hazards, poor living conditions and other challenges associated with purlieus. This paper examined the influence of green urbanism on psychological wellbeing (physical symptoms and positive functioning) of residents in urban sprawls. Participants were 240 residents of purlieus’ in Ota, Ogun, Nigeria randomly selected to participate in the study. They completed standardized questionnaires which measured demographic variables, Physical symptoms and Positive Functioning. Data analysis was done using inferential statistics. Findings indicated that Physical Symptoms (PS) means score was found to increase as number of children in the family increases. Positive functioning (PF), among the participants were found to decrease as the number of children in the families increases. Physical symptoms (PS) increases as the length of stay in the houses increases among the participants while Positive functioning (PF) was found to be decreasing. Most of the houses were constructed in the 2000s yet they do not meet the standard practice in sustainable buildings. The poorly built houses are situated in unhygienic environment where basic amenities are unavailable. The implication of this is that the occupants of these building are prone to high level of physical symptoms such as stomach upset, headache, backache, have trouble sleeping, diarrhea, dizziness, tiredness and fatigue. The result of the study has addressed health related issues in built environment as well as showed that built environment should have an organic sustainable content (green living initiatives) for healthy living and psychological wellbeing.
Socio-Cultural Resilience to Domestic Space Change, the Benin Traditional City Experience, Nigeria
(2021) Ekhaese, Eghosa N.; Evbuoma, I. K.; George, T. O.
Research over time has revealed that activity spaces in domestic home have undergone evolution, adaptation and resilience over the years across Benin residential zones, Nigeria. Space segments/activities sections like cooking/eating, household goods storage, visitors and conveniences sections have somehow remain unchanged in terms of function, meaning, and arrangement. The study identified socio-cultural factors as responsible for resilience of domestic space to change in Benin domestic architecture across Benin City. The paper engaged both qualitative and quantitative research method. Triangulation was adopted for collection through focused group discussion using Semi-structured interview guide, questionnaire, observation guide and photographs. Factor analysis was use to analysis of data in order to reduce the identified socio-cultural factors to sizeable portion. The finding showed that, whilst some activity space, it size and location have evolved in Benin contemporary architecture, the style has remained intact. For instance some activity spaces in some residential zone of the city have been adapted to suit the new realities. Further observation itemised the socio-cultural factors that are responsible for resilient to change in Benin domestic architecture. Result of research underscores the role of culture in process of architectural development amidst rapid urbanization. Research upon completion is expected to be a good case study for measuring resilience to evolution of spaces in typical house setting in any African traditional city.
Lipid peroxidation and activity of some antioxidative enzymes in the root of maize (Zea mays) cultivated on cadmium contamination soil
(Journal / Scientia Africana / Vol. 20, 2021-04-23) Ugbeni, O.C.; Dania, Omoremime Elizabeth; Eruotor, H.
In this study, we examined the tolerance capacity of Zea mays to cadmium pollution. Soil was treated with varied concentrations of Cadmium; 5 mg, 10 mg, 20 mg and 30 mg/kg soil and Zea mays planted. Root samples were collected in weeks 3, 4, 5 and 6. Activities of Peroxidase, catalase superoxide dismutase, and lipid peroxidation were investigated. Decrease in peroxidase activity was extremely significant (p <0.05) in weeks 4 and 5 while that of week 6 was not significantly (p > 0.05) different from normal. The decrease correlated with increase in Cadmium concentration. However, at the highest concentration of 30 mg/kg of soil the trend was not significant. Increase in the activity of catalase was recorded in weeks 3 and 6. This increase didn’t follow a particular trend but at higher concentration of Cd and long term exposure, it became apparent. There was a negative correlation between catalase activity and lipid peroxidation. In week 3, catalase activity was not significant (p > 0.05) and lipid peroxidation was significant (p < 0.05) while at week 4, catalase activity was significant (p < 0.05) and lipid peroxidation was not significant (p = 0.8432). Catalase activity was not significant (p = 0.2753) at week 5 and lipid peroxidation was significant (p = 0.0030). At week 6 when catalase activity became extremely significant (p < 0.05), lipid peroxidation had a p value of 0.0128. Generally no significant activity (p > 0.05) was observed for superoxide dismutase. A significant increase in absorption of cadmium (p = 0.0374) at 30mg/kg soil was observed between weeks 5 and 6. It was also observed that cadmium had no significant effect (p > 0.05) on the root weight during the period of study. It’s suggestive therefore Cadmium contamination of soil could affect growth of maize and induce oxidative stress.
Space Adaptability Strategies and Building Performance in Selected Entertainment Centres in Nigeria
(3rd International Conference on Energy and Sustainable Environment, 2022) Akerele, Fiyinfoluwa Stacy; Oluwatayo, Adedapo Adewunmi; Kolade, Kehinde; Olusore, Shalom Pelumi
Studies have shown that there is a need to adapt buildings over their lifespan to environmental, economic and social changes. This will help enhance the decision-making process of building design and the development of a more sustainable built environment over a while. Anecdotal evidence suggests that entertainment centres in Nigeria often cease to meet their performance criteria over time as the entertainment needs of users change. The purpose of this study is to identify space adaptability strategies that influence the performance level of selected entertainment centres in Nigeria. Four entertainment centres were selected for this study. Respondents were users of the buildings. A total of 86 copies of the questionnaire were retrieved from the users of these selected entertainment centres. The data were analysed statistically using descriptive, predictive and inferential statistics. The sample size from each of the buildings was determined using census sampling with a total of 86 respondents collectively from the four selected entertainment centres. The findings from the study suggested that only 7 of the 37 identified adaptability strategies had a significant effect on the performance of these entertainment centres. These include space modularity, versatility of spaces, convertibility of spaces, reversible spaces, space scalability, space mobility and adjustability. The results of this study showed that while space modularity has a negative influence on the perception of security, social and cultural performance; versatility of spaces positively influenced that performance dimension. This study, therefore, concluded that, concerning entertainment centres, adaptability may not have influenced the performance in terms of functionality, equitable use, efficiency and psychological pleasure; however, security of such facilities may be enhanced by providing versatile spaces. The study recommended that architects should focus on versatility of spaces in the design of entertainment centres as it has been discovered to positively influence the security, social and cultural performance level of entertainment centres.
Assessment of Lighting Strategies in Art Galleries: A Comparative Case Study of Selected Art Galleries in Lagos State
(3rd International Conference on Energy and Sustainable Environment (IOP Publishing), 2022) Ekhaese, Eghosa N.; Solaja, A. O.
Light is so important in our everyday lives that it effects user experiences of spaces as well as the user's overall well-being for a large portion of the day in the built environment. Lighting, among the other aspects that make up the design of spaces, is an important characteristic in a building because it is the primary means of appreciating art and culture. The study aimed to assess purposively selected art galleries as the basis for determining the best lighting strategies to be adopted in the design of an art gallery in Lagos, Nigeria. This study addressed two key objectives – identify the existing lighting strategies used in the assessed art galleries to recommend the best lighting strategies to be used and ascertain how the lighting strategies are implemented. A qualitative research method using case study approach was employed in the research. Content and narrative analyses were used to analyse data. Findings show a significant need for daylight to be implemented alongside artificial lighting in an art gallery. The results align with current global trends towards sustainability.
Mass Residential Housing Projects and Sustainable Construction Practices
(ECS Transactions, 107 (1), 2022) Aderogba, A. M.; Faremi, J. O.; Ajayi, O. O.
The construction industry significantly consumes enormous energy and emits greenhouse gases due to its effort in bridging the housing deficit arising from increased population both in developed and developing countries. The study assesses the extent to which sustainable building construction practices are incorporated in the construction of buildings in Lagos State, Nigeria. A survey of 100 construction professionals and mass housing unit owners was conducted on frequently implemented sustainable practices on buildings projects and the perceived satisfaction of users of buildings on sustainability features. A total of 80 questionnaires were successfully retrieved and processed for analysis using frequency tables and relative implementation index. The result shows that sustainable practices that are often incorporated into mass housing projects during construction include downsizing the dominant use of incandescent bulbs and replacing them with energy-saving bulbs. The study concludes that there is a significant relationship between sustainable practices and the building users’ satisfaction.
A censorious appraisal of the oil well acidizing corrosion inhibitors
(Journal of Petroleum Science and Engineering 215, 2022) Solomon, Moses M.; Uzoma, Ifeanyi E.; Olugbuyiro, Joseph A.O.; Ademosun, Olabisi T.
Well acidizing is a common stimulation technique for maximizing the output of oil reservoirs. It helps to overcome the low permeability of wellbore by creating new flow channels or enlarging old ones. Corrosion challenge is encountered during the process since tubings are metallic. Corrosion inhibitors are the defence mechanism used in mitigating corrosion problem during acidizing. This review has identified and grouped acidizing corrosion inhibitors into organic-, and polymer-based. The performance of these inhibitors at temperatures of ≥60 ◦C and acid concentration of ≥15 wt% is considered. It is noted that greater percentage of studies revolve round the 60 ◦C. Above 100 ◦C, the number of scientific articles decreased considerably. Four classes of intensifiers for acidizing corrosion inhibitors have been identified: formic acid, potassium iodide, copper iodide, and antimony chloride. Their chemistries have been discussed. The research gaps identified include (i) scanty information on acidizing inhibitors at temperatures ≥150 ◦C, (ii) limited information on natural polymers and plant biomaterials as acidizing inhibitors, (iii) scanty information on the mechanism of inhibition at temperatures ≥150 ◦C, and (v) limited information on the composition of corrosion products under acidizing conditions. Thus, recommendations for future researches have been given.
Value Pertinence for Residential Property Investments in Christian Mission Estates: An Investigation of Canaan City in Ogun State, Nigeria
(Journal of Civil Engineering and Urbanism Volume 12, Issue 4: 61-69;, 2022-12) Akinjare, Omolade Adedoyin; Akinjare, Victoria Adeola; Ayedun, C. A.; Oluwatobi, Afolasade Olubunmi; Alexander, Matilder Nomteik
The rapid expansion and urbanization of Lagos state of Nigeria due to uncontrolled rural - urban migration seems to have succeeded in transforming the peri-urban areas of Ota, Ogun state into a mini economic hub, thus propelling property values skywards. The present study ascertains if passing rents, as well as sales value for the various apartments in Canaan city estate as charged by the project developer, is overpriced, and underpriced or fair-priced. The rental data collected from the residents of the estate were compared with rental opinion obtained from practicing estate surveyors and valuers in Ogun State. 240 questionnaires were administered to residents of the estate while 22 questionnaires were administered to registered estate surveying and valuation firms. Interviews and questionnaires were deployed to solicit data from the Physical Planning Department (PPD) being the managers of the estate. The retrieved data were then collated and presented using figures and Tables. Findings showed that the passing rents for all cadres of residential apartments in the estate were discounted with the most discounted apartment type being the 2-bedroom luxury flats and the least discounted apartment type being the 4-bedroom semi-detached houses. For sales value, findings showed that the high end apartments – the detached houses, semi-detached and also the 3- bedroom terrace houses were hugely discounted. Unfortunately, the 1-bedroom and 2-bedroom flats were the least discounted while the 2-bedroom luxury flats and 3-bedroom flats were either within range or slightly overpriced. The study concluded that the passing rents were underpriced due to the income nature of tenants and subsequently, the sales value proposed by the developer of the estate was underpriced. The study recommended an upward review of sales prices should the estate proprietor still continue with the sales of its apartment within Canaan city

(Green Chemistry for Sustainable Water Purification, 2022-12-27) Oladipo, Gabriel Opeoluwa; Alayande, Samson Oluwagbemiga; Ogunyinka, Opeyemi O; Akinsiku, Anuoluwa Abimbola; Akinsipo-Oyelaja, Oyesolape Basirat; Ofudje, Edwin Andrew; Bolarinwa, Hakeem S.; Akinlabi, Akinola Kehinde; Msagati, Titus. A.M.
Anionic dye is a notable constituent of textile effluent, which renders water unsafe for human and animal use. A notable approach to mitigating effluent is the use of membranes. In this study, a mixed matrix technique was adopted for the preparation of composite membranes. The composite membranes consist of crumb rubber filled with nanoparticles, respectively. The membranes were characterized by Fourier transform spectroscopy, scanning electron microscopy coupled with energy dispersive x-ray, thermogravimetric analyser, and drop shape analyzer. The photocatalytic activities of the mixed matrix membranes were investigated with anionic dye in the UV/visible region. Photocatalytic activity of composite membranes showed high degradation with an apparent rate constant. This study presents a rubber-based membrane for wastewater treatment.
STATISTICAL MODELING OF THE RELATIONSHIP BETWEEN CITESCORE AND JOURNAL PERCENTILES OF BUILDING AND CONSTRUCTION JOURNALS
(Pushpa Publishing House, 2023) Peter, N. J.; Iroham, Chukwuemeka O.
Building and construction are one of the major subject categories in Scopus, Elsevier. Building and construction journals are journals that publish articles and review papers in all areas of building, construction, structures, construction materials, civil engineering, and building and construction management amongst others. This paper proposes a modified quartile model which can be used to predict the journal percentile using the CiteScore as the independent variable. The model evaluation metrics signal a good fit and the proposed model yielded journal percentile (JP) close to the original JP. The knowledge of the CiteScore can now be used to predict the percentile and by extension, the quartile of journals in building and construction in Scopus or Web of Science.
Go‑ahead urban liveability indicators (ULI) influence on residents’ well‑being: a case for Lekki‑Lagos, Nigeria
(GeoJournal, 2023) Ekhaese, Eghosa N.; Asinobi, Amarachi A.
According to the UN habitat report on the new agenda 2030, 3.5 billion persons live in cities currently. By 2030, about 5 billion people are likely to be in cities. Liveability quests are an urban concern across the globe. And it is a holistic connection that involves five key aspects: healthy and ample neighbourhood, convenience and green mobility, diverse and buoyant local economy, lively public places/spaces and affordability. Therefore, the study investigates the impact of urban liveability indicators on inhabitants’ well-being in Lekki, Lagos, Nigeria. By: identifying the UN-Habitat and WHO checklist for urban liveability as an assessment of the current liveability conditions in Lekki, Lagos, identifying the urban liveability indicators in Lekki, Lagos, and investigating the effect of urban liveability indicators (ULI) on residents’ well-being/health in Lekki, Lagos. The research employed a mixed research methods (quantitative and qualitative methods) and used a case study as the research strategy Semi-structure Questionnaires (quantitative survey method) and In-depth interview guide, Focused Group discussion (FGD), observation Guide, WHO Urban Liveability checklist (qualitative research method) were an instrument for data collection. The data analysis and discussion were chronologically along with the objectives, and study findings established that the Lekki neighbourhood has high liveability standards. However, there is a strong correlation between ULI and residents’ well-being/health. The issue of urban liveability is germane to urban residents’ health, wellbeing, happiness and longevity. In conclusion, the guideline for urban liveability identified in the study may be a handy tool for a key interested party in cities to plan for a better world.
