This study was conducted to assess the water quality of inlet and outlet canals connected Nuwarawewa, Anuradhapura, Sri Lanka. Seven major inlets and one outlet canals connected to Nuwarawewa, Anuradhapura was identified. Water samples were collected from a selected location of each inlet and outlet canal in one-month interval for three months period. Soil samples (0-30 cm) were collected from each selected location at the second time point. Water quality parameters such as pH, Electrical conductivity (EC), Dissolved Oxygen (DO), Total Dissolved (TDS), NO3--N, NH4+-N, available phosphorus (Av. P), alkalinity and heavy metals (Cd and As) concentrations were determined in each water sample. Soil samples were analyzed for pH, EC, total N, Av. P, Cd and total As contents. The results showed that pH, DO, TDS, NH4+-N, and Av. P of some in some tested water samples were higher and other parameters were within permissible levels according to WHO drinking water quality standards. Higher total N in all tested soil samples and lower Av. P values in many tested soil samples (except one) were observed in comparison to the reference values in literature. According to European Regulatory Standards, As concentrations in many soil samples (except one) within the permissible levels and Cd was not detected. Considerable temporal variations in water quality parameters were observed in inlet and outlet canals during the study period. The chemical properties of soil inside each canal were significantly altered by the quality of water being carried out by the respective canal. These result further revealed that impacts of surrounding land use on water pollution in inlet water canals connected to Nuwarawewa are higher. It could be concluded that the implementation of a pollution management plan is required to prevent further pollution through continuous future researches.

The Internet of Things (IOT) has become important to almost every area of life due to the huge advantages it possesses. African countries including Nigeria are clamouring for the implementation and deployment of IOT devices to ease the difficulties individuals face in performing their various tasks. Due to the fact that the African region depends hugely on agriculture, this paper focuses on IOT for smart agriculture. This paper first defines the basic concepts where IOT could benefit agriculture in Nigeria and Africa. Furthermore, it reviews the areas where IOT can be applied to agriculture. The benefits of IOT in agriculture to Nigeria and Africa are discussed. Lastly, conclusion and lessons learnt from the review are presented.

Diophantine equations are very useful while studying certain problems of coordinate geometry, cryptography, trigonometry and applied algebra. In the present paper, authors studied the non-linear Diophantine equation [19]2m+[2^(2r+1)-1]=ρ2, where m,r,ρ are whole numbers, for determining its solution in whole number. Results show that the non-linear Diophantine equation [19]2m+[2^(2r+1)-1]=ρ2, where m,r,ρ are whole numbers, has no solution in whole number.
