Abstract Hydraulic conductivity is one of the soil properties that determine the flow of water under hydraulic gradient. Laboratory experiment was conducted using soil samples collected from University of Maiduguri Teaching and Research farm to investigate the effect of compaction, moisture content and rate so organic matter incorporation on saturated hydraulic conductivity of a sandy […]

Abstract This study employs a univariate Autoregressive Integrated Moving Average (ARIMA) homoskedastic model in conjunction with Box and Jenkins modeling procedure to model and forecast annual Consumer Price Index (CPI) data in Nigeria from 1950 to 2014. The annual data on Consumer Price Index is obtained as secondary data from Penn World Table, the National […]

Abstract On the basis of the sources and harm the ink wastewater analysis, summed up the four ink wastewater treatment methods: adsorption, coagulation, chemical oxidation, biological method, and the four methods were compared. He points out the advantages and disadvantages of each method and conditions of use, the treatment effect. [File Type:PDF]

Abstract A field trial was carried out at the University of Khartoum farm, Shambat, Sudan, for two consecutive seasons (2006-2007) and (2007-2008).The aim of the research was to determine the effect of the time and depth of application of aqueous waste ammonia, as a nitrogen fertilizer, on a leaf of nitrogen, phosphorus and potassium of […]

Abstract The development of city gas is closely related to the level of national economy and the improvement of social life. Human resource management is an important part of urban gas enterprise management, enterprise reform is the reform of all aspects of the enterprise, human resources management can smoothly transition to the process of enterprise […]

Abstract Thin films of hydroxypropyl methylcellulose (HPMC) are prepared by solution casting technique and exposed to UV/ozone for different exposure times. The effect of exposure on the optical properties such as: near infrared (NIR), transmittance spectra in the spectral region 250–2500 nm of the films are studied. The changes in the optical parameters including: The […]

Abstract The Leibnitz-Macluarin Method (LMM) via successive differential coefficients has been employed to proffer series solution of the nonlinear equation arising in the convective straight fins with temperature-dependent thermal conductivity problem. Solutions are presented for the dimensionless temperature distribution and fin efficiency of the nonlinear equation. Parametric analyses indicated two dominant non-dimensional parameters describing the […]

Abstract Big data refers to massive amount of data that are so large that traditional processing tools cannot cope. It is produced by emails, online transactions, medical records, etc. It is a high-volume, high-velocity, and high-variety information that require special information processing tools. This paper presents a brief introduction on big data for engineers. [File […]

Abstract A mathematical model is a tool used to obtain information about the behavior of a system. The mathematical models can be used to have a preliminary knowledge about the functioning of a system, reducing the product costs and improving the performance. In this study, the modified models of several existing models, Gompertz, Orskov, Logistic […]

Abstract DNA computing is essential computation using biological molecules rather than traditional silicon chips. In recent years, DNA computing has been a research tool for solving complex problems. Despite this, it is still not easy to understand. The aim of this paper is present DNA computing in simple terms that a beginner can understand. [File […]
