The Intranet Mailing System is only useful within a company or organization. In today’s fast-paced society, where every qualified person is in desperate need of work, people join places and work at unusual hours. Because of the organizations shift schedules, it can be difficult for one shift’s employee to communicate with another shift’s employee. In these cases, Intranet Mailing comes in handy. If a firm has an Intranet Mailing System available to all of its employees, the system proves its worth. Employees can register and send emails to any other registered employee, making communication more efficient easier.

In this study, we established a qualitative understanding of the physical quantities which characterize nucleon-nucleon interaction and pion nucleon based on the fact that nuclear forces at low energies in the nucleon-nucleon system are mainly determined by the one-pion exchange mechanism. The result of the computation governed by Yukawa potential as recommended by meson field theory at lowest energies scattering length and effective range shows that the highest energy is obtained at the interaction of proton-proton where the scattering length is in the range of (2.85 – 2.90) g/cm while the effective range is recorded to low. On the other hand, high energy value was obtained at a value of (2.00 -2.05) g/cm of effective range interaction a while low energy was recorded in the case of scattering length at the same length. The charge pion –nucleon coupling constant is obtained at a value of this physical quantity expressed excellent agreement with the experimental value of . This shows electromagnetic interaction associated with the correction will be likely added or removed from the experimental values of the nuclear – coulomb-low energy parameters of scattering.

Recently, deep eutectic solvent (DES); being as novel and green solvent has attracted increasing interest in different areas of sciences, engineering, and medicine due to its excellent physicochemical and thermal properties. The formulation and classification of DES is dependent solely on the hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD) components and their proportions. Its superiority to ionic liquids (ILs) encompasses the cheap and available starting/raw materials, and the ease of formulation and storage. DESs has gained a very wide distribution and application in various researches and industrial processes; the widest distribution being its application in synthesis. Its uses span as solvent for laboratory and industrial pretreatment, extraction, separation and purification of both inorganic metallic components and organic compounds. Though they possess core characteristics that are similar to those of ILs, DESs has been pronounced as capacity options attributive to its physicochemical properties. Notwithstanding the innumerable uses and application of DESs, their chemical, biological and physical characteristics have not been completely investigated. Despite the benefits the solvent has limitations of corrosion, high viscosity, mixture instability and lack of physicochemical information. This review seeks to provide a brief introduction to DES while highlighting some latent potentials and limitations of the novel solvent in the various fields of application.

Aisha, S.H. And Sani, B.
Mathematics Department, Ahmadu Bello University Zaria.
This paper considers the problem of computing optimal ordering policy for single product under a periodic review inventory system with stochastic demand. Adopting a Markov decision approach, the states of the Markov chain represent possible states of demand for the models. The objective is to determine in each period of the planning horizon, an optimal EOQ so that the long run profits are maximized for a given state of demands. The decision of how much quantity to order or not to order are made using a 2- period dynamic programming over a finite planning horizon. A numerical example demonstrates the existence of an optimal state, economic order quantity, as well as corresponding profits.

The Issues and Challenges of Machine Learning
Edino Kennedy O.; & Okorodudu Joseph
Computer Science Department, Delta State Polytechnic Otefe-Oghara
Present day computer applications require the representation of huge amount of complex knowledge and data in programs and thus require tremendous amount of work. Our ability to code the computer fall short of the demand for applications. If the computers are endowed with the learning ability, then our burden of coding the machine is eased (or at least reduced). This is particularly true for developing expert systems where the “bottle-neck” is to extract the expert’s knowledge and feed the knowledge to computers. Machine Learning will produce smarter computers capable of all the above intelligent behaviour. The area of Machine Learning deals with the design of programs that can learn rules from data, adapt to changes, and improve performance with experience. In addition to being one of the initial dreams of computer science, Machine Learning has become crucial as computers are expected to solve increasingly complex problems and become more integrated into our daily lives. This is a hard problem since making a machine learn from its computational tasks requires work at several levels, and complexities and ambiguities arise at each of those levels. In this research work, we examine the type of machine learning problems and the steps to solve a machine learning problem.

This paper is a mathematical numerical simulation solution approach to the model of coupled partial linear differential equations of grain stored fumigation. The model is based on phenomena of advection-diffusion transport process of solute mass for the fumigation distribution of phosphine gas concentration in a cylindrical silo containing grain and the model is one dimensional advection diffusion coupled with partial linear differential equation. The model solved using finite difference method (FDM) while Octave software is used in the simulation. The results showed the convergence of FDM by the error convergence on FDM, it also shows that the solution has less error if the increment is smaller. The results showered that during fumigation process, the behaviour of phosphine gas concentration based on graph of the results, the length of the time phosphine gas concentration could be taken for covering the silo is independent of the amount of boundary fumigant concentration (BFC) injected to the silo. While for concentration in the grain inside the silo, the time is depending on the BFC where the more BFC in the silo, the higher concentration received by the grain. Furthermore, when the velocity increase, the time taking for phosphine gas concentration during fumigation is reduced. In addition, when less amount of BFC is injected to the silo and higher velocity of the model, then during the fumigation processes the least amount of concentration the grain absorbs.
Keywords: Numerical simulation of finite difference method on model of fumigant transport.

Biometric technologies have the potential to provide convincing evidence of who actually performs a given transaction, because each person’s biometric characteristics are thought to be unique and difficult to reproduce. Biometric technologies work by measuring and analysing human physiological or behavioural characteristics. Physiological characteristics are those associated with a part of the body. The fingerprint is probably the best known example; however, face and hand shape, and retina and iris patterns are also examples of physiological characteristics. This paper aims to briefly address some of the biometric technologies used how biometric systems work. Also a brief summary of identification process and identity life cycle management.

Effect of Oil Spillage in Oceans
Chinelo Gloria Ike
Department of Science Laboratory Technology (Microbiology Option), School of Applied Sciences, Federal Polytechnic Oko
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity. Oil is the most common pollutant in the oceans. The fate of spilled oil depends on the oil properties and on environmental conditions. It is very important to recognize the dynamic nature of spilled oil because the properties of spilled oil can change over time. It is important to monitor the continuous changes in the properties of the spilled oil, as response strategies may have to be modified. Oil Properties crude or refined oils vary in their physical and chemical characteristics. These characteristics affect their volatility, toxicity, weathering rate and persistence. Oil spills have a devastating and long term impact on waterways and coastal areas around the world. Seabirds are frequently affected by offshore oil spills. Spills can severely harm turtle eggs and damage fish larvae, causing deformities. Shellfish and corals are particularly at risk since they cannot escape the runaway slick. Oil spills are also responsible for tainting algae, which perform a vital role in water ecosystems. Oil spills can be partially controlled by chemical dispersion, combustion, mechanical containment and adsorption. As the world advances technologically, unfortunately accidents do happen and spills reoccur more frequently than we would like. This paper focuses on the society to accept responsibility for repair of damage to environment through human intervention and carefully targeted cleanup activities.

Application of Markov-switch models to Nigeria’s economy especially the macroeconomic variables in order to determine how it relates to policy making cannot be under-emphasized. This study investigates the relationship between gross domestic products and inflation in Nigeria using a time series data from 1960 – 2019 with the aid of Markov switching regression model. Markov switching vector autoregressive (MSVAR) model is used to determine the structure of inflation in Nigeria.The results from this study concludes that the Markov-Switching Regression model is a high-degree flexible model having captured regime shifts in the mean, variance and the parameters of the vector autoregressive process. Also, it is observed that inflation series is well fitted by the MSVAR model and the filtered probabilities can be deduced. This was accounted for by the estimated parameters and the filtered probability plots of regime 1 and 2 and they have high transition probabilities of 0.985513 and 0.97144. The expected durations that corresponds the probability in a regime are 69 and 35 respectively showing that inflation on the economic growth will remain in the origin state almost two times before moving to the second state. Hence, this study concludes that there is regime switching structure in the dataset.

In this study, lead sulphide (PbS) thin films were produced on glass slide substrates using a simple and easy-to-control approach, followed by large-area films, utilizing a chemical bath deposition method (CBD). The reactive substances used to obtained the PbS layers were (Pb(NO3)2), (NaOH), (SC(NH2)2) and H2O for different concentration and dipping times, at constant room temperature. The surface morphology was determined by Field Emission Scanning Electron Microscopy (FE-SEM). Spectroscopy measurements of transmission, reflection, and absorption were used to determine the optical characteristics. Changes in dipping durations and reaction solution concentrations were used to alter the thickness of these films. Experiments revealed that the shape and optical characteristics of PbS films were modified by growth conditions and thermal treatment.
Design Considerations of Anaerobic Digester for Production of Biogas Loaded With Cow Manure
Yakub Baba Ahmad
Department of Mechanical Engineering Technology, Federal Polytechnic Mubi, P M B 35, Mubi, Adamawa State Nigeria
Nigeria plays an important role in the development and propagation of renewable energy technology. The production of biogas is of growing interest as depletion of fossil-fuel resources. Although the production of biogas through anaerobic digestion is not a new idea, commercial anaerobic digestion processes are often operated at well below their ideal performance due to a diversity of factors. The study designed a domestic biogas plant, which if adopted can reduce the bioenergy consumption by a significant percentage. From the research and design, a family in rural area with between 5 to 10 cows can produce a minimum of 2 to 3 m3 of gas which is adequate for lighting and cooking needs of a rural family with an average of 4 to 6. However, there exists a dearth of literature on the design considerations that would lead in the development of anaerobic digesters aimed at creating useful commodities from the ever-abundant bio-waste. Consequently, this paper provides the important issues and analyses about the design of a household anaerobic digester.

Biogas originates from bacteria in the process of bio-degradation of organic material under anaerobic condition. Biogas is a mixture of gases that is composed chiefly of methane (CH4), Carbon-dioxide (CO2), Hydrogen (H2), and Hydrogen sulphide (H2S2). The production of biogas through anaerobic digestion was carried out using cow dung. Three drums digester were used for the study. The pH of the slurry before anaerobic digestion was 6.2 for cow dung. The pH, Temperature and proximate analysis of the sample, before digestions were determined using standard method. The total aerobic and anaerobic counts for the cow dung are 89×105 and 75×105 before digestion, 49×105 and 82×105 after digestion. The cultural morphology revealed Gram positive rods with creamy irregular edges and the identified organisms are Bacillus species and Clostridium species. Table four contains the result of the daily biogas yield in millimetre and daily temperature reading after 2 weeks (14days) retention time which show a higher gas yield of 58ml at day 10. The result of this research shows that high quality of biogas can be produced using cow dung.
