The effects of dampness have become a major problem when it invades into building. It is also a possible source of or a contributor to illness and it encourages deterioration in the fabric of the building. With an emphasis on existing buildings and some coverage of the design of new buildings, the objectives of this research are to investigate the causes of dampness during and after the construction of buildings, identify the effects of dampness on the building and its occupants and offer recommendations on the above mention issues. The level of dampness causes and effects differ across geographic areas, climates, and building types. A descriptive survey technique was used to gather information about rising damp in the municipality which includes questionnaires, interviews, and personal observations. According to the findings, the condition resulting in rising dampness to the base of walls was the lack of incorporation of damp-proof courses during construction. Also, the problem of rising dampness reoccurs shortly after treatment because of the application of the wrong treatment method as well as the absence of damp treatment specialists. The effects of rising dampness led to damage to plaster work, crumbling of masonry, peeling of paintwork, efflorescence on wall surfaces, uncomfortable, unattractive rooms, and the cost of painting a room or building yearly. From the findings, it is recommended that damp proof courses (DPCs) should be placed through the full thickness of the base of walls below floor level to form an impervious layer that keeps rising damp out of the buildings.","PeriodicalId":125730,"journal":{"name":"Open Access Research Journal of Engineering and Technology","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139205303","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}

The study area and the control experiment were conducted simultaneously for a period of thirty (30) days between December 2022-January 2023 (Dry Season). Samples were prepared and deposition fluxes (DF) were determined. The particulates were taken to the Central Research Laboratory, Tanke in Ilorin for characterization using X-ray Fluorescence (XRF) spectrometer. EF was also determined. Thirteen elements Fe, Ag, Cd, Zn, Sn, Ti, In, Co, Mn, Pd, Rh and Ru were characterized from the samples collected at the study area while Twenty-one Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Ge, As, Zr, Sr, Pb, W, Po and Ac elements were characterized from the samples collected at the control unit of the experiment. The EF of the detected elements both in the study area and in the control, experiment was determined.

Technology-enabled teacher education programs are embracing digital tools to enhance pedagogy, provide adaptive learning experiences, foster global connectivity, and promote data-driven decision-making. These programs prepare educators for 21st-century classrooms, equipping them with the skills needed for 21st-century classrooms. However, concerns about overreliance on technology persist, emphasizing the importance of striking a balance between digital tools and traditional teaching methods. Unequal access to technology and the digital divide poses significant challenges, necessitating infrastructure development and equitable access initiatives. Ensuring technological literacy among educators and students is crucial, as these programs demand a certain level of digital proficiency. Balancing theory with practice in these programs is essential for their continued success. Understanding learner perceptions and addressing challenges is key in shaping the evolution of teacher education programs that effectively prepare educators for the dynamic demands of modern classrooms.

Extensive literature underscores the urgency of modernizing the sector by embracing new technologies such as digital prototyping and advanced manufacturing processes. In light of these considerations, this article aims to assess the range of materials available for 3D printing to determine the feasibility of integrating this technology into the Brazilian civil construction industry (BCI). Through a comprehensive analysis of materials currently in use, drawn from scientific research, it becomes evident that mortar-based materials are emerging as a preferred choice for 3D printing components within civil construction. Considering that the Brazilian construction sector already heavily relies on cement as its primary material for constructing the built environment, a promising landscape unfolds for the gradual adoption and integration of three-dimensional printing technology into the industry. This alignment with existing practices and materials positions the BCI favourably for embracing the potential of 3D printing.","PeriodicalId":125730,"journal":{"name":"Open Access Research Journal of Engineering and Technology","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136343731","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}

With an effective size of 0.45 mm, a uniformity factor of 1.5 and a porosity of 0.6, the filter material was able to filter water with a high iron content and other parameters. The backwash speed of the sand filter is 1.44 m/s (86.4 m/h). At this speed, the pressure was sufficient to cause the media to expand and boil, so that the iron sludge, flakes and other dirt remained in the filter. Nine (9) daily inflows and outflows at depths of 60 cm, 70 cm and 80 cm were determined. An iron removal efficiency of 99.1% was achieved at a depth of 60 cm and 90.63% at a depth of 80 cm. Similarly, the model was able to remove physical and organoleptic parameters (color, turbidity, fluorine, manganese, nitrite, Ph, zinc, E-coli and total coliforms). The technology developed in this research can be used as an alternative, simple and cost-effective way to remove iron and other contaminants from groundwater.","PeriodicalId":125730,"journal":{"name":"Open Access Research Journal of Engineering and Technology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136277272","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}

By storing the block in many locations across a distributed network arrangement, it offers a public ledger system that combines public key encryption of all transactions to solve the double spending problem, making change impossible and therefore more secure.
