Policy response to the pattern of growth does not match the pace of rapid housing development in Lagos peri-urban settlements.  This research examined the characteristics of housing in the peri-urban settlements of Lagos State, Nigeria and specifically investigated the drivers of housing characteristics, socio-economic attributes of the residents, the quality of housing and the challenges of the management of the emerging peri-urban housing developments.  Using a case study approach, housing characteristics in peri-urban settlements in Ajah Eti osa Local Government  Areas  were  selected  to  represent  the  rapidly  urbanizing  metropolitan  peripheral  areas in  Lagos  State.    Data were collected through primary and secondary sources.  Findings revealed  that  major drivers  of  housing  development  in  the  study  area  are  principally  land  affordability,  low  cost  of living,  easy  linkage  and  proximity  to  urban  centres,  and  provision  of  better  quality  housing  through exclusive  gated  housing  development.  The findings  also  demonstrate  that  different  housing initiatives  in  the  peri-urban  settlements  performed  differently  in  typology  and  resident’s perception.  Socio-economic attributes  revealed  a  multi-cultural  households  composition, reasonable  literacy  level  and  mostly  male  headed  households.  Findings also  showed  factors  that influence  dwelling  quality  in  the  study  area  are  choice  of  building  materials,  neighbourhood  and locational  quality.  Challenges to governance are location-specific and mostly poor infrastructural development.   It is recommended that improved  quality  and  user  performance  peri-urban housing development  can  be  achieved  through  residents’  participation  in  housing  policy  design  and  also by  timely  regional  policy  response  to  the  pace  of  housing  characteristics in  Lagos  peri-urban settlements.

{"title":"ENGINE PERFORMANCE ANALYSIS OF PALM KERNEL OIL-BASED BIODIESEL BLENDS ON SPEED VARIATIONS OF A 4-CYLINDER ENGINE AT CONSTANT TORQUE","authors":"","doi":"10.53555/nnmce.v9i4.1640","DOIUrl":"https://doi.org/10.53555/nnmce.v9i4.1640","url":null,"abstract":"Biodiesel made from the transesterification of plant-derived oils is an important alternative fuel source for diesel engines. Several disparate studies have emphasized the significance of biodiesels in emission reduction and engine efficiency. The present study examined the effect of using palm kernel oil (PKO), pure petroleum diesel, and its blends on the fuel consumption rates, energy expended, brake-specific fuel consumption, and brake thermal efficiency of a four-cylinder tractor under varying operating speeds (700 – 1900rpm) at constant torque. The study was conducted at a large farming site in Anambra State, Nigeria. The findings indicated that PKO biodiesel blends had the overall optimum energy output, fuel consumption rates, and brake-specific fuel consumption, respectively, at the highest engine speed of 1900. Although B10's rating of 60.6% for thermal brake efficiency was impressive, it was lower than B100's 66.95 %. Based on the results, B10 is the best gasoline for testing and may be used as a replacement fuel in four-cylinder farm tractor engines with no modifications. The study concludes that biodiesel blends showed potential as an alternative to fossil diesel.","PeriodicalId":126133,"journal":{"name":"Journal of Advance Research in Mechanical & Civil Engineering (ISSN: 2208-2379)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131032439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, the business sector has observed a growing concern about incubation. The goal of the current project is to build a prototype of an intelligent and automated incubator that uses an inductive heating system powered by renewable energy. A microcontroller is used inside the incubator to monitor and maintain the appropriate temperature and humidity levels in the space within the device. In order to perform calibration, data logging, and analysis, a GSM module was built. After extensive testing, it was concluded that the new system provides efficiency and dependability to the poultry farming industry.","PeriodicalId":126133,"journal":{"name":"Journal of Advance Research in Mechanical & Civil Engineering (ISSN: 2208-2379)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123210417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"EXAMINING THE EFFECT OF CLIMATE CHANGE ON THE SUSCEPTIBILITY OF ROAD PAVEMENTS IN SOUTH-SOUTH NIGERIA USING THE DELPHI METHOD","authors":"Eric E. Isemede","doi":"10.53555/nnmce.v9i3.1578","DOIUrl":"https://doi.org/10.53555/nnmce.v9i3.1578","url":null,"abstract":"Asphalt pavements constitute a high portion of Nigeria's roadways, which have high traffic volumes. The potential deterioration in the long-term performance of these pavements due to climate change has not been given much research attention. To this extent, the present study evaluated the pavement susceptibility of Federal roads in Edo state of South-South Nigeria. The study employed the Delphi technique to examine expert opinions. The standard deviation of the answers to two rounds of questionnaires was used to evaluate the consensus reached by the 10-person Delphi panel. The result showed that one of the four federal roads analyzed in the study was classified as having a high susceptibility, two were classified as having a medium susceptibility, and the remaining road was classified as having a low susceptibility. This research demonstrates that the Delphi technique, which incorporates both objective and subjective assessments, can comprehensively evaluate road pavements' vulnerability to climate change. Therefore, the government should employ adaptive maintenance plans for the roads' varying degrees of susceptibility.","PeriodicalId":126133,"journal":{"name":"Journal of Advance Research in Mechanical & Civil Engineering (ISSN: 2208-2379)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129838610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
