The research encompassed particle size determination and Atterberg limits testing to classify the samples, primarily composed of lateritic soil. The results detailed the particle size distribution and indicated the soil's composition, predominantly sand with gravel and unaccounted finer silt content. The Atterberg limits testing revealed variations in plastic and liquid limits across different cement percentages. Additionally, dynamic and static compaction tests were performed, indicating Optimum Moisture Content (OMC) and Maximum Dry Density (MDD). The static compaction involved replacing proportions of bulk sand with cement for each percentage addition. The study achieved its objective of understanding soil properties for stabilization purposes, offering insights into the impact of varying cement content on soil characteristics and compaction. The abstract emphasizes the comprehensive investigation into lateritic soil properties and the influence of cement stabilization, vital for engineering applications in the Takie area of Ogbomoso.

Urbanization accounts for the major reason which pulls migration, and the environment is the fiber and bedrock upon which Urbanization thrives. As Urbanization occurs, the environment is modified to accommodate its new population. Ideally, in modifying the environment to accommodate urbanization, care should be taken to avoid any form of exploitation, degradation, abuse, and misuse. In the Nigerian context however, urbanization has occurred rapidly through unsustainable activities and lifestyles that both deplete and pressure the environment and the lives of the very inhabitants it should so dutifully protect. This research paper analyzes how Nigeria's rapid urban growth is affecting landscape design and sustainability. It highlights the history of urbanization both globally and locally, as well as addressing the menaces and negative impact of the movement citing examples in certain Nigerian cities. It goes on to establish the role of landscape in Urban Spaces and how they play Sustainability, Health, Aesthetic, Social, Agricultural, Ecological, Economical, Acoustic and Conservational roles in impacting the urban spaces in Nigeria. It concludes by recommending strategies for ensuring success in the use of landscape as a tool for mitigating the negative effects of rapid urbanization in Nigeria.

With this move, cities, which may have begun as small compact units with just enough facilities to accommodate its pioneering dwellers begin to grow. This growth is called Urbanization, and it also occurs naturally through the increased births in the city. Believed to have begun in 4300-3100BCE in the Uruk period of ancient Mesopotamia when a certain "prosperous and efficient village attracted the attention of other less prosperous tribes who then attached themselves to the successful settlement" (Mark, 2014). Slowly but surely, this urbanization pattern has repeated itself in all nations around the globe further compounding the climate change crisis. Asia, which has 30% of the global land mass, and is home to nearly half the world's population, has urbanization traced to rural-urban migration inspired by administrative, commercial, and maritime cities which now have gained political significance. When analyzed individually, East and NorthEast Asia is rapidly urbanizing. SouthEast Asia features relatively high urbanization rates, South and SouthWest Asia are one of the least urbanized with high Urbanization rates centered in the oil-rich central Asian countries and very low in the "non-fossil-fuel-producing and less diversified economies, such as Kyrgyzstan and Tajikistan." China, believed to have half of its population living in cities is hailed for its successful urbanization practice which was achieved by either limiting rural-urban migration or directing this movement away from the big cities towards growing or medium-sized ones, drastically limiting the number of slums. This urbanization has been experienced in every country, at different rates with an estimate showing that more than 50% of the world's population presently live in urban areas. Urbanization in Nigeria The urbanization in Nigeria is both rapid and continuing. 5 out of the 30 largest urbanized cities in Africa are in Nigeria, and her urban population is recorded to be growing at an alarming rate of 4.3 percent per annum, with an estimate that in 2037, her urban population would have doubled(URBANET, 2018). The main cause of urbanization in Nigeria can be summarized by the rural push and urban pull effect (Jedwab, Christiaensen, and Gindelsky, 2014). The rural-push effect refers to the unpleasant situations that make living in rural areas undesirable for Nigerians, and these include insecurity, rural poverty, lack of amenities and infrastructure, etc. The

In response to the escalating urban issues, a collaborative effort has emerged among local government bodies, businesses, non-profit organizations, and the residents themselves, all united by the vision of creating smarter cities. The smart city concept centers on the harmonious integration and synergy of human capital, social assets, and Information and Communication Technology (ICT) infrastructure. Its objective is to promote sustainable economic development and make better the overall quality of life. This paper therefore focused to define smart cities and ways of improving smartness of city. It also adopted review of literatures to explore the elements and components of smart city in order to arrive at a comprehensive defi...

However, the use of stabilised bricks has not been fully incorporated into high rise building construction due to its overall weight which is one of the major considerations for multi-story buildings. This research on light weight bricks was carried out to ascertain its suitability for various applications in high rise building and engineering constructions. The production was done using different percentages of Ordinary Portland Cement (OPC) and Saw Dust (SD) to establish the percentage required for light weight construction while maintaining the optimum compressive strength required for performance in building construction comparable with that of a sandcrete block to confirm its suitability for use in...

The Impact test was carried out according to ASTM [1] and ASTM [2] using a manually operated impact-tester machine. Mat Lab R2013a model was used to analyze the results of the impact strength. The average impact strength obtained were 98.776, 91.904, 85.463, 79.021 and 69.144 kJ/m2 for 0, 5, 10, 15 and 20% Ash contents respectively. The impact strength remained constant at 118.530 kJ/m2 with the addition of CCA at 0, 5, 10 and 15% but decreased at 20% cement replacement at the first trial. Mathematical models were developed for predicting impact strength of KF and CCA roofing tiles using Mat Lab R2013a model. The results show that corn cob ash and kenaf fiber can be used for sustainable housing development.

Metal detector is a device which responds to metal that may not be readily apparent, metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. In such a typical metal detector, the coils are coaxially arranged with the transmitting coil in the center and two receiving coils on the sides. The receiving coils are connected to a differential amplifier. When the magnetic field generated in the transmitting coil is disturbed by metal objects, the amplitude and phase of the output voltage of the differential amplifier change and thus the existence of foreign metal pieces are detected. The most commonly used metal detection technology is very low frequency (VLF), also known as induction balance. In this type of metal detector, there are two rings: an outer coil called the transmitter coil and an inner coil called the receiver coil. The transmitter coil has an electric current running through it, which creates an electromagnetic field. This magnetic pulse interacts with any conductive object it passes over, causing that object to create a weaker magnetic field of its own; it is this magnetic pulse from the object that the receiver coil senses. The receiver coil is shielded from the transmitter coil's magnetic field, but can pick up magnetic pulses sent by other objects. The receiver coil amplifies these frequencies and sends them to the control box for analysis.
