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. Eco-friendly packaging is a vital element in an organization marketing strategy. It interacts with each other variables of the eco-friendly packaging in order to dictate the effectiveness of the market mix variable.

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 = {The supply of electric power is seen as a very important and key driver in the efforts to diversify and grow the economy of Nigeria to boost revenue sources and creat employment opportunities for the teaming youth. 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.

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

abstract = {Machine learning models are combined to output a better skillful model. The output model(s) to use or trust to solve a problem is subject to its record of performances. 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 = {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 = {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 = {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. 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. 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 = {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, low permeability, among others. The black cotton (expansive) soil was obtained from a borrow pit on the sedimentary formation 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. In line with BS 1377 (1990) and other relevant codes, California Bearing-Ratio (CBR) tests were conducted on the materials of black cotton on sedimentary formation to determine the suitability of the natural expansive soil for use as sub-grade, sub-base or base materials. It is evidently clear from the results that the CBR value of the soil is low and could be classified as poor soil. Even though the soil could be used as sub-grade, and in order to reduce the overall construction cost of highways, it will still be required that soil be stabilized with any of the locally available stabilized agents or materials.

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. The eggshell wastes were taken from Obasanjo Farms, Ota, Ogun State, Nigeria along Ilaro-Owode Road, Ilaro, Ogun State, Nigeria. The eggshells were grounded into powder and then substituted for black cotton soil from 0% to 30% at 10% intervals while 0% eggshell powder 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 eggshell powder for the determination of liquid limit, plastic limit, etc. It is evidently clear from the results that the percentage shrinkage limit became constant at 30% eggshell powder substitution in black cotton soil on sedimentary formation which is an indication of constancy of volume.
