abstract = {Water, a vital natural resource, is indispensable for sustaining life on Earth. However, rapid societal development and human activities have led to contamination and depletion of water resources, necessitating effective water quality monitoring systems. This article proposes an Internet of Things (IoT)-based approach for real-time monitoring of water quality parameters, with a specific focus on electrical conductivity (EC). Traditional methods of water quality assessment involve manual sampling and laboratory testing, which are time-consuming and often lack real-time data. The proposed system integrates a microcontroller, electrical conductivity sensor, and web tools to monitor EC levels in various water sources (Surface Water, Well Water, Factory Treated Water). The study discusses the development and testing of the IoT-based system, highlighting its potential applications in diverse sectors such as pharmaceuticals, drinking water production, and food processing. Additionally, recommendations for further research and implications for water management are discussed.

abstract = {Curtailing room temperature to ambient temperature has a significant impact on our environment, energy consumption, and personal comfort. Ambient temperature could be defined as the temperature of the surrounding area or the external environment. By reducing room temperature to match the ambient temperature, the use of artificial cooling or heating systems, such as air conditioners or heaters can be minimized. The research developed an automated system using an ESP8266 Microcontroller, DHT11 Temperature Sensor, 5V Relay Module, Fan, and Power Supply to control room temperature by comparing room and ambient temperatures and adjusting fan operation accordingly for energy conservation, environmental, economic, and comfort-related benefits of aligning room temperature with ambient temperature. Room temperatures were highest in R1 (three users) at 34.33°C (PM) and 34.25°C (AM), indicating user presence maintains heat. R2 (two users) had slightly lower temperatures at 33.81°C (PM) and 33.33°C (AM), showing fewer users generate less heat. R3 (no users) showed significantly lower temperatures at 26.87°C (PM) and 26.35°C (AM), highlighting that absence of users leads to lower heat accumulation. ANOVA results show a significant effect of room conditions on temperature but no significant effect of the time of day. The Duncan Multiple Range Test indicates notable differences between room temperatures, affirming that user presence is a dominant factor in temperature variation.

This study examined media ownership and ethical standard compliance in OGTV and Rock city FM, Abeokuta. Source credibility theory was considered as theoretical framework to explain the relationship between broadcast ownership and ethical standard compliance within the stations. The study adopted in-depth survey design using key informant interview (KII) guide as the instruments. A sample of core management staff from OGTV and Rock city FM was selected. Data were analysed qualitatively. Findings of the study established that OGTVand Rock city FM based their programming policy for public good and interest as affirmed by Key informant interviewees. It was evidenced from the KIIs’ submission that the two stations to a greater extent complied with NBC’s code of ethics. It was also disclosed by the KII that the major challenges facing the stations generally were lack of adequate funding and required digital broadcast facilities as recommended by NBC. The study came to the conclusion that staff performance in both stations was impacted by ownership structure, control, which influence an iota of non-compliance with ethical standard.

abstract = {The issue of sexism in media has been a persistent concern, with numerous studies highlighting how media portrayals can reinforce gender stereotypes and biases. However, the specific impact of media framing of sexism on marriage stability, particularly among educated couples remains underexplored. Hence, this study examine relationship between media framing of sexism and marriage stability among educated couples in Abeokuta, metropolis. The general objective of the study was to ascertain likely significant relationship between the media framing of sexism and marriage stability among educated couples. The study employed survey research method while 400 educated couples with tertiary to post-graduate educational backgrounds within Abeokuta metropolis covering four local governments were selected as sample size through cluster sampling. A self-administered questionnaire was used to generate data. Inferential statistics was used to analyzed data gathered. Findings showed significant difference exist between sexist media content and traditional gender roles as the (t-cal.=32.3) which is greater than t-critical (t-crit.=1.96) with mean difference of (M=2.29)of sexist media content and traditional gender roles(M=1.77). The result also revealed that significant moderation of the level of media literacy on media framing of sexism and marriage stability based (t-cal. =32.03) which is greater than (t-crit.=1.90) with mean difference (M=2.29) of media framing of sexism and marriage stability (M=2.20).The study concluded that media framing of sexism significantly contributes to reinforcing traditional gender roles, which can lead to conflicts and reduced stability in marriages which further validate the significant relationship that exist between exposure to sexist media content and the perceptions of traditional gender roles among educated couples. Based on the findings it was recommended that there should be continuous public awareness campaigns aimed at promoting gender equality and challenging traditional gender roles.

abstract = {The implementation of effective irrigation and aeration techniques is vital in enhancing plant growth and striving towards optimal crop yields. This study examines the effects of varying field capacities (FC) and two distinct aeration methods on plant growth (Africa-spinach - Amaranth cruentus). The experiment aimed to investigate the effects of different field capacity levels (100% FC, 75% FC, 65% FC, and 55% FC) and aeration methods (air injected into irrigated soil and air injected into irrigation water) on plant growth. Several growth parameters, including Shoot fresh weight, number of leaves at various weeks after planting, and plant height, were measured to assess development. Linear regression model was employed to quantify the relationships between these factors and their impact on plant growth. Field capacity and water use efficiency significantly increase Shoot fresh weight, while the aeration methods show marginal effects. The study finds that field capacity and water use efficiency are key factors influencing Shoot fresh weight, while aeration methods have a less significant impact on growth. Correlation matrix reveals that SFW water use efficiency is strongly positively correlated with Shoot fresh weight, indicating its crucial role in optimizing plant growth, while other variables show weaker correlations, underscoring the complexity of factors influencing growth.

abstract = {Most manufacturing organization set various eco-friendly packaging for the sales of their products. In managing the eco-friendly packaging of product which is part of company’s eco-friendly packaging, management must first of all decide on its eco-friendly packaging goal, policy and strategy about a given product to satisfy consumers, efficient eco-friendly packaging of goods and services which is often a critical factor in successful operation of any business enterprise. The most common mistake is that eco-friendly packaging is too cost oriented, it is not revised often enough to capitalize on market changes, it is also set independent of the rest of the eco-friendly packaging other then as an interior element of market positioning strategy and tactics of marketing is not varied enough to different product item. This research work used information or data obtained from both the primary and secondary source of data. The study population encompassed 200 which comprises of 60 Top level managers and 140 middle level manager of Intercontinental Distiller Nig. Ltd. Nigeria Plc, Ikeja branch, Lagos State .The probability sampling method were adopted in this study with the aid of Simple random sampling. The sample size in this research work was obtained using Taro Yamane formula. Based on the findings of this research work it was observed that eco-friendly packaging is the tactic that company use to increase sales and maximize profits by selling their goods and services for appropriate tactics of marketing. This strategy takes into account the cost of the product as well as labor, advertising expenses, competitive mix, trade margins, and the overall market conditions to determine the sale tactics of marketing.

abstract = {The exact combination of leverage utilized to fund a company's assets and activities is referred to as its capital structure. Equity is a much costlier, long-term form of financing with greater financial flexibility from a company standpoint. Borrowing, on the other hand, is a less costly source of capital with a limited term, which legally obliges the company to commit to fixed, promised outflows of funds. These financial choices, that could be influenced by capital structure policies as well as goals established by management and the board of directors, determine a company's capital structure. The sample size is drawn from eight listed oil and gas marketing and producing companies in Nigeria. The ordinary least square method (OLS) of multiple regressions was utilized in this study. The data was then analyzed using econometric tools like multiple regressions to ascertain the impact of capital structure on performance of listed oil and gas companies in Nigeria.It was discovered that all oil and gas firms fund their operations with more debt rather than equity because of the huge capital outlay involved. Additionally, it was discovered that STD, LTD, TDE, and INC had a positive but insignificant impact on Nigeria's quoted oil firms' performance. The study's findings recommend adding more factors to the model when assessing how capital structure affects company performance.

abstract = {Information and communications technologies are now integral to the conduct of military operations. Forces around the world are committing to constant technological innovation, especially since the attacks of September 11, 2001 (9/11), and the subsequent War on Terror. Robust satellite communications are important to achieving decision superiority, timely response and precision by the military. This is what is required by the military at this time of serious security threat confronting the nation from within and outside the country to wriggle out of the present security challenges. Information coordination that is made available and accessible to all command involved in a theater of operation is key to a successful operation. Consolidating the military strength under a dedicated satellite will be a new path to having interconnectivity and coordination of military powers and resources at any location responding to centralized command and control as well as information sharing across the globe. To achieve this, there is need to leverage both mature and emerging space technologies such as optical and laser communications technologies, dedicated military satellite, constellations of miniaturized satellite so as to overcome dependence on resource-intensive, limited coverage area, and increasingly vulnerable application of line of sight radio communication. This paper proposes what a dedicated military satellite for our nation should composed of with other possible mature and emerging technologies to confront the security challenges that have bedeviled the nation

However, there are several problems and challenges that are adversely affecting the electricity sector in the Nigeria. A critical aspect of these challenges is energy theft, which include unethical practices such as unlawful direct hooking from power line, by-passing of electricity meter, injection of foreign elements into the energy meter, drilling holes in the meter and assignment of illegal amount of energy units to consumer. In this paper, a phased deployment of smart energy meters and other managerial procedures are recommended to drastically reduced incidences of energy theft with subsequent increased in revenue collection. This paper would be useful to policy makers who are trying to come up with effective solutions aimed at boosting revenue leading to improvement in power generation sector, transmission process and distribution.

In this study, ensemble machine learning algorithm is used in anaconda3 environment to combine the predictions from multiple machine learning classification models: K-Nearest Neighbors (KNN), Support Vector Machine Enabled Radial Basis Function (SVM-RBF), Decision Trees (DT), Random forest (RF), Multilayer perceptron (MLP) on sale dataset. The dataset consist of three levels of sale channels (In-person, Instagram and Whatsapp) and three levels of movement restriction period (COVID- 19, nationwide restriction due to national election and no restriction movement). The results revealed that KNN, SVM-RBF, DT, RF, MLP, and the combined model had: accuracy score of 62.99 %, 91.57 %, 52.45 %, 89.93 %, 33.02 % and 49.41 % respectively; the Matthews correlation coefficient (MCC) gave 50.84 %, 88.85 %, 34.76 %, 86.61 %, 6.12 % and 29.95 % respectively; F1 score also gave 59.92 %, 91.24 %, 44.83 %, 89.58 %, 19.58 % and 43.59 % respectively. It can be seen from the results that combining models for machine learning operation does not necessarily give higher performances in all score category but the confidence in individual model to accurately learn on the dataset or from neighbor model on its own.

abstract = {A good knowledge of the effect of rain in the design of satellite and terrestrial microwave radio links is of interest to engineers and scientists. In equal importance is the role plays by tropical rainfall in agricultural practices and in ensuring the constant availability of atmospheric wind circulation as a result of latent heat energy produced by tropical rainfall. A good prediction often required for guaranteeing high level of accuracy of the rain rate distribution from the lowest rain rate value to the highest. The present work proposes an improved model that expresses rain rate as a function of alpha and beta obtained at 0.01% of the time when tested. Observational data from tropical regions especially along equatorial region were used, with two locations in Nigeria. The results obtained are shown to be reliable for discussing the performance of the rain intensities of between 5mm/h to 200mm/h.

abstract = {The significant advances in cellular networks and mobile devices have led to a rapidly growing demand for high speed multimedia applications. The co-existence of macro eNodeBs and the additional low power nodes (LPNs) could lead to higher interference in LTE-Advanced Heterogeneous Networks (HetNets). Due to high transmission power emitted by macro cell, very few users will be off-loaded to nearby pico cell which leads to underutilization of pico cells in HetNets. Hence, in practical HetNets scenario, Range Extension (RE) is a promising scheme to utilize the low power node (LPN) resources more effectively and improve the cell edge performance. With the help of CRE, user equipment (UE) will add a bias value to actual signal strength received from pico cell and thereby offload their traffic from macro cell to pico cell. However, if the bias value is not properly set in a way to capture the users’ distribution and network density, it may introduce more interference. In this paper, a solution of Intelligent Pico Cell Range Expansion which calculates the optimal and effective bias value for each mobile station independently is been proposed. Simulation results demonstrate that the proposed scheme can reduce the number of outage and increase the number of offloaded UE in HetNet.

abstract = {As an important component of cancer control programs, the scarcity of radiation therapy resources in Nigeria is becoming more severe as cancer incidence increases. This study analyses and suggests possible solutions to the causes of this rather disastrous state of radiation therapy in Nigeria. In the study the available radiotherapy centers in Nigeria were analyzed, while relevant information about the types and number of radiotherapy equipments was obtained using retrospective method of data collection. Results showed that between 2001and 2014 the number of megavoltage therapy machines has reached nine from five, with at least one therapy machine situated in nine of the radiotherapy center. Nigeria is the most populated African country with a population of at least 160 million people based on 2006 population census and average annual growth rate of 3.10%, giving only a marginal improvement in the radiotherapy service. The results also showed that these facilities are concentrated in the southern and northern states of the country. Although progress has been made in the establishment of radiation therapy services in Nigeria, a large need still exists for training of manpower in all fields of specialization related to radiotherapy service in order to adequately care for the multitude of cancer patients. Radiotherapy centers need to be established in Nigeria, due to the increasing number of patients requiring the facility. Awareness of such centers should be raised among medical practitioners and the populace.

abstract = {Black cotton soils are characterized by their damaging attributes which include erosion, expansion, excessive creep, high compressibility, heaving, subsidence, dispersion and swelling. Problematic soils have some additional unique properties including low bearing capacity, high water absorption, and low permeability, among others. Palm kernel shells are not common material in the construction industry. This is either because they are not available in very large quantities as sand or gravel, or because their use for such has not been encouraged. For some time now, the stakeholders’ have been clamoring for the use of local materials in the construction industry to limit the cost of construction. There has therefore been a greater call for the sourcing and development of alternative, non-conventional local construction materials. Therefore there is need to look at the possibility of mitigating the problems of black cotton soils using locally available materials. One of such is palm kernel shells. The black cotton (expansive) soil was obtained from a borrow pit on the sedimentary formation at Idogo in Ogun State, South-Western Nigeria. The borrow site lies within the coordinates 6⁰ 50' 6" N and 2⁰ 58' 42" E. The black cotton soils used in the study were collected from depths between 0.3-1.0m below ground level. The palm kernel shell wastes were taken from palm oil producing plant along Ilaro-Owode Road, Ilaro, Ogun State, Nigeria. The quantity of water which was used to obtain optimum moisture content and maximum dry density for black cotton soil (i. e. control, 0%) was determined. This water was then used to run 90% consolidation tests. The palm kernel shells were broken into pieces passing through 5mm sieve and then substituted for black cotton soil from 0% to 50% at 10% intervals while 0% palm kernel shell substitution served as control experiment. In line with BS 1377 (1990) and other relevant codes, consolidation tests were conducted on the saturated and unsaturated composite materials of black cotton on sedimentary formation mixed varying degrees of palm kernel shells for the determination of consolidation parameters and possible settlement potentials. This will help to find a way of incorporating solid palm kernel shells into engineering advantage thereby helping to reduce the nuisance and menace caused by solid palm kernel shell waste in the environment and leading to a more stable environment.

abstract = {Expansive soils are one of those kinds of soils whose volume change takes place while it comes in contact with water. It expands during the rainy season due to intake of water and shrinks during dry season. The wetting and drying process of a sub-grade layer composed of black cotton soil result into failure of pavements in form of settlement and cracking. Therefore, prior to construction of a road on such sub-grade, it is important either to remove the existing soil and replace it with a non-expansive soil or to improve the engineering properties of the existing soil by stabilization using additives such as egg shell powder and palm kernel shell which is source locally The black cotton (expansive) soil was obtained from a borrow pit on the basement complex at Igbo-Ora in Oyo State, South-Western Nigeria. The borrow site lies within the coordinates Longitude 7⁰24'45" and latitude 3⁰18'34". Another black cotton (expansive) soil was obtained from a borrow pit on the sedimentary formation at Idogo in Ogun State, South-Western Nigeria.

In line with BS 1377 (1990) and other relevant codes, compaction tests were conducted on the black cotton soils on basement complex and sedimentary formation for the determination of maximum dry density, bulk density and optimum moisture content of the natural soils. From the results, the bulk and dry densities of black cotton soil on the sedimentary formation are higher than that of basement complex while the later required more test water content to achieve the maximum bulk and dry densities. The optimum moisture content of basement complex is higher than that of sedimentary formation. It could be seen from the results that the type of formation played a prominent role in their behaviors to the compactive efforts.

abstract = {Expansive soils tend to be strong in its dry state but when in a wet condition, it tends to lose its strength. The low strength and excessive volume changes of black cotton soil make their use in constructions very difficult. The properties of the black cotton soil may be altered in many ways through mechanical, chemical and other means. Therefore, it becomes very important to investigate the physical and engineering properties associated with the black cotton soil especially as a construction material. The black cotton (expansive) soil was obtained from a borrow pit on the basement complex at Igbo-Ora in Oyo State, South-Western Nigeria. The borrow site lies within the coordinates Longitude 7⁰24'45" and latitude 3⁰18'34". The black cotton soils used in the study were collected from depths between 0.3-1.0m below ground level. The palm kernel shell wastes were taken from palm oil producing plant along Ilaro-Owode Road, Ilaro, Ogun State, Nigeria. The palm kernel shells were broken into pieces passing through 5mm sieve and then substituted for black cotton soil from 0% to 30% at 10% intervals while 0% palm kernel shell substitution served as control experiment. In line with BS 1377 (1990) and other relevant codes, consistency tests were conducted on the composite materials of black cotton on basement complex mixed varying degrees of palm kernel shells, for the determination of liquid limit, plastic limit, etc. From the results, shrinkage limit reduced from 2.0cm for 0% substitution to 1.5cm for 30% substitution of palm kernel shell substitution in black cotton soil on basement complex. The percentage shrinkage limit became constant at 30% palm kernel shell substitution which is an indication that the optimum percentage substitution of palm kernel shell in black cotton soil on basement complex is 30%.

abstract = {The disposal of waste materials is a big problem in the developing country like Nigeria. As a result of lack of land required for disposal technique. The substitution of these waste materials in the form of stabilizing agent in the soil stabilization is a modern approach by which waste materials can be of advantage in civil engineering projects. The idea behind the technique of soil stabilization is that the finer particles of soil are replaced with coarser particles of the waste material so that a composite material is formed having an interlocking ability with better geotechnical properties. The black cotton (expansive) soil was obtained from a borrow pit on the sedimentary formation at Idogo in Ogun State, South-Western Nigeria. The borrow site lies within the coordinates 6⁰ 50' 6" N and 2⁰ 58' 42" E. The black cotton soils used in the study were collected from depths between 0.3-1.0m below ground level. The palm kernel shell wastes were taken from palm oil producing plant along Ilaro-Owode Road, Ilaro, Ogun State, Nigeria. The quantity of water which was used to obtain optimum moisture content and maximum dry density for black cotton soil (i. e. control, 0%) was determined. This water was then used to run consistency tests. The palm kernel shells were broken into pieces passing through 5mm sieve and then substituted for black cotton soil from 0% to 30% at 10% intervals while 0% palm kernel shell substitution served as control experiment. In line with BS 1377 (1990) and other relevant codes, consistency tests were conducted on the composite materials of black cotton on sedimentary formation mixed varying degrees of palm kernel shells for the determination of liquid limit, plastic limit, etc. The observed or measured parameters reduce as the palm kernel shell substitutions increases. It is evidently clear from the results that the percentage shrinkage limit became constant at 30% palm kernel shell substitution in black cotton soil on sedimentary formation which is an indication of constancy of volume.

abstract = {Soils which undergo large volume changes with change in water content like black cotton may be troublesome if used for highway or railroad fills or if structural foundations are placed on them. The soil volume changes result in bumps in roads and cracks in structures since the volume changes may not, and usually will not, be equal. The liquid and plastic limits may be used to predict potential problems in soils due to volume changes. However, to obtain quantitative indication of how much change in moisture can occur before any appreciable volume change occurs and to obtain, if volume change does occur, an indication of the amount of change, a shrinkage-limit test should be performed. The black cotton (expansive) soil used in this study was obtained from a borrow pit on the basement complex at Idogo in Yewa South Local Government, Ogun State, South-Western Nigeria. The borrow site lies within the coordinates 6⁰ 50' 6" N and 2⁰ 58' 42" N. The black cotton soils used in the study were collected from depths between 0.3-1.0m below ground level.

abstract = {Eggshell is an agricultural waste which has been found to possess pozolanic property and has been used as partial replacement of cement in other materials. It is against this background that it is been used as a stabilizing agent on problematic lateritic soil. The laterite soil was obtained from a borrow pit at Ajegunle along Ilaro-Papalanto road, Yewa South Local Government Area in Ogun State, Nigeria. The borrow pit site lies within the coordinates 6°53’11.81”N and 3°7’44.88”E.The eggshells were obtained from Obasanjo Farms Nigeria Limited, Ota, Ogun State, Nigeria and grounded to powder. In line with BS 1377 (1990) and other relevant codes of practice, consolidation tests on 1hour and 24hours soaked samples were conducted to determine the relevant consolidation parameters and settlement indices. Eggshell powder was substituted in the lateritic soil (sedimentary formation) in range of 0% to 50% with 0% serving as control experiment for both the 1-hour soaked and 24-hour soaked samples. The results indicated that for the 1hour soaked sample, the value of the coefficient of consolidation is within the range of 1.22 at 50% substitution to 1.68 at 10% substitution, while the range is 0.63 at 50% substitution to 1.60 at 20% substitution. Finally, from the results, coefficient of consolidation reduces as the percentage eggshell powder substitution increases.

abstract = {Irrigation scheduling is pivotal for precision and sustainable farming, optimum crop growth and yield, as well as water use efficiency (WUE), especially in water-limited areas. The study aims to determine water use efficiency, as well as the effect of water stress on the yield of pepper under drip irrigation system. The study was conducted at the Agricultural and Bio-environmental Engineering Research Farm of the Federal Polytechnic Ilaro, Ogun State, Nigeria. Four irrigation treatments were investigated. The experiment had four irrigation levels. The first irrigation application treatment (A) consists of 100% of actual crop evapotranspiration (ET). The second (B) was 75% ET. The third (C) was 50% ET and fourth (D) consist of 25% ET. The experiment was arranged in a randomized complete block design (RCBD) with four replications and 2 varieties of pepper: Capsicum annum and Capsicum frutescens. Irrigation applications were applied for 3 weeks after transplanting and thereafter continued for the whole growing season. Parameters such as such soil, agronomic and crop’s consumption water use were measured and the results subjected to statistical analysis. The results indicated that there was a significant difference between the WUE, yields and growth parameters under different levels of irrigation in the two pepper varieties. The results showed that water use efficiency, yields and other agronomic parameters such as plant height, number of leaves and fruit length and weight were higher during the studies periods for both pepper varieties under treatments A and B compared with other treatments C and D respectively. However, there was no significant difference in WUE of treatments A and B. Statistical analysis among the agronomic parameters showed a significant difference (p<0.05) in all the treatments. It was concluded that irrigating at 75% ET in the study area will result in water saving and maximum sustainable production of these pepper varieties.

abstract = {Fire alarm system is used to avoid the incidence of fire outbreaks and to protect lives and property. They find direct applications in the protection of the premises of industries, private and commercial buildings. Meanwhile, an ideal fire alarm system should be able to sense the required heat or high temperatures, transmit signals, and give alert with notification when there is an occurrence of fire. Previously proposed fire alarm systems come in one form or the other, but some of them are based on unfounded assumptions and without any practical foundations. Few with related design features lack human factors and ergonomics in their design and no basis for evaluation. Thus, proposed in this work is an automatic heat detector and microcontroller-based fire alarm system. It employs the use of detection system that operates as the fire detector, buzzer for alarming and motor pump to stop the fire and the entire system is controlled by microcontroller. The microcontroller is programmed using C-Programming in such way that the system can detects smoke, light, flame, heat etc. The prototype of the system was tested in real-life and it was found to work perfectly, the detail of its development was explained while recommendations for its full-scale implementation were also given.

abstract = {Heavy metal pollution caused by various man-made activities, which hazardously affects the environment, has become a universal concern. The aim of the study is to evaluate heavy metal concentration, pollution level and health risk assessment in air conditioner filter dust in hospitals in Port Harcourt. Dust samples were collected from air conditioner filter, and then a composite sample was made for each of the ten (10) hospitals then transported to the laboratory of FATLAB Nigeria Company. 1g of the dust was digested using Aqua regia method. Heavy metal analysis was carried using iCE 3000 Series Atomic Absorption Spectrometer. Contamination factor, I-geo value and EF were used to determine the degree of pollution, possible source was determined using Pearson correlation, principal component analysis (PCA) and cluster analysis (CA) while Health risk assessment was conducted to evaluate the non-cancer and cancer risks to children and adult in the environment. The result shows that the concentration of chromium in 52.6% (10 of 19) of the samples were higher than the Canada value (64 mg/kg), 15.8% (3 of 19) were higher than the UK value (200 mg/kg) while 5.3% (1 of 19) were higher than the Dutch value (580 mg/kg). Zinc concentration in 52.6 % (10 of 19) of the samples were higher than the Canada value (360 mg/kg) while 31.6 % (6 of 19) were higher than the Dutch value (720 mg/kg). CF value show very high contamination with Cd, I-geo indicate moderate pollution from Cd and Zn in the filter dust, EF value shows an extremely high enrichment and very high enrichment from Cd and Zn respectively. Pearson correlation shows an obviously strong relationship between Fe, Pb, Zn and Cu suggesting an emergence of heavy metal from anthropogenic source possibly resulting from office equipment, furniture, cabinetry and components of the air conditioners. More so, PCA show a strong loading with Co, Fe, Pb suggesting and emergence from anthropogenic with an element of natural sources. The primary exposure of pathway to children and adult population were ingestion. Children in the hospital environment are at risk of being exposed to the dust than the adult, basically may be due to this playing behaviour. The children and adult in the hospital environment are not at risk of developing cancer from Cd and Pb on exposure while Cr (3.24E-04, 1.39E-04) respectively, demands close attention in the environment since it is at the radar of exceeding the permissible limit. Therefore, a frequent assessment and monitoring of Air conditioner filter in the hospitals is suggested.

Heart-rate is associated with hypoxia (low blood oxygen level) which on its own could lead to permanent brain damage. This research develops a heart- rate and blood oxyhemoglobin monitoring device using the MAX30100 IC (for the heart-rate and pulse oximeter reading), an Arduino UNO IC (ATMEGA328P) as the central controller, an MLX90614 infrared temperature module and a piezo buzzer for alarm system. The measurement period was 30 seconds and a 16 by 2 LCD displayed the heart-rate and blood oxygen concentration (SpO2) content in beats per minute and percentages % respectively. An alarm was triggered if the heart-rate exceeded 100 beats per minute or the SpO2 was less than 94%. The results obtained were compared to standard devices and the errors obtained were within acceptable limit. The device could be used as alternative in health care centers and could also incorporate a GSM Module to send messages to a physician and finally biometric could be introduced to be used as an identifier to know the specific user.

abstract = {Improving the engineering properties of lateritic soils by including stabilizing agent, such as cement, lime, bitumen, etc. helps to reduce settlement underneath the engineering structures. Plastic pollution is the accumulation of plastic objects and particles in the Earth's environment that adversely affects wildlife, and human. Living organisms, particularly marine animals, can be harmed by problems related to ingestion of plastic waste or through exposure to chemicals within plastics that interfere with their physiology. The lateritic soil used in this study was taken from the sedimentary formation located at Abalabi ( 53’ 13.758”N, 7’ 59.994”E), Ajegunle, along Papalanto-Ilaro road, Ogun State, Nigeria plastic wastes were taken from different location in Ilaro, Ogun State, Nigeria. The plastic wastes were cut into pieces passing through 5mm sieve and then substituted for lateritic soil in the range of 0% to 50% at 5% intervals with 0% plastic pellet substitution serving as control experiment. In line with BS 1377 (1990), California Bearing-Ratio tests were conducted on the composite materials at different test water contents for all the substitutions. From the results, California Bearing-Ratio value increased gradually as plastic pellet substitution increases. In addition to this, 5% and 10% substitutions have the maximum CBR value at both top and bottom. Furthermore, between 25% to 50% plastic pellet substitutions, CBR values are highest from their first test water content. The composite material at 5% to 10% plastic pellet substitution could be used for road base and sub base, most especially rural roads. Therefore, environment risk and hazard caused by plastic waste could be greatly reduced, if not completely eliminated.

abstract = {Recycling helps to reduce the pollution caused by waste and huge amounts of energy are used when making products from raw materials. Recycling requires much less energy and therefore helps to preserve natural resources in this case, natural (raw) rubber used in the production of plastic products. This study is aimed at providing alternatives use for plastic wastes in the construction industries. The lateritic soil used in this study was taken on the sedimentary formation located at Abalabi ( 53’ 13.758”N, 7’ 59.994”E), Ajegunle, along Papalanto-Ilaro road, Ogun State, Nigeria and plastic wastes were taken from different locations in Ilaro, Ogun State, Nigeria. The plastic wastes were cut into pieces passing through 5mm sieve and then substituted for lateritic soil in the range of 0% to 50% at 5% intervals while 0% plastic pellet substitution served as control experiment. In line with BS 1377 (1990), compaction tests were carried out on the composite materials to determine the various optimum moisture contents and maximum dry densities at different test water contents for all the substitutions. From the results, it was observed that 0% plastic pellet substitution (i. e. control experiment) has the maximum dry density value. In addition to this, 35% to 40% plastic pellet substitution has the maximum optimum moisture content value while increase in plastic pellet substitution reduces the density of the composite material. The composite material at 10% plastic pallet substitution can be used for road base and sub base and it is therefore a possible alternative solution for safe disposal of the plastic wastes from causing nuisance. Therefore environmental risk and hazard caused by plastic waste would be greatly reduced, if not completely eliminated.

abstract = {There is increase in demand for safe, durable and economical roads, especially in the rural areas. The high cost of stabilizing agent, environmental effects of dumping of agricultural waste such as palm kernel shell and implications involved in the process of transporting materials from borrow pit pose serious threats to human and the environment. Therefore, there is need to look for affordable alternatives. The lateritic soil used in this study was taken from the sedimentary formation located at Abalabi ( 53’ 13.758”N, 7’ 59.994”E), Ajegunle, along Papalanto-Ilaro road, Ogun State, Nigeria and palm kernel shell wastes were taken from oil palm producing plant at Iweke along Ilaro-Owode Road, Ilaro, Ogun State, Nigeria. The palm kernel shells were broken into pieces passing through 5mm sieve and then substituted for lateritic soil in the range of 0% to 50% at 5% intervals with 0% palm kernel shell substitution serving as control experiment. In line with BS 1377 (1990), pressure loads were applied on the composite materials and California Bearing-Ratio tests conducted at different test water contents for all the substitutions. From the results, California Bearing-Ratio value increased gradually as palm kernel shell substitution increases while 25% palm kernel shell substitution has the maximum CBR value at both top and bottom. In addition, for the 40% to 50% palm kernel shell substitutions, maximum CBR values were observed from their initial test water content. The composite material with palm kernel shell at 25% can be used for road base and sub base. Finally, recycling of palm kernel shell wastes is an alternative solution of safe disposal of the agro waste called palm kernel shell. There environmental risk and hazard caused by palm kernel shell wastes could be greatly reduced if not completely eliminated.
