Abstract- In the design of machine component parts, it is a good practice to determine the cause of failure of all designed mechanical components and resolve the cause(s) of the failure in the final design. This is to prevent frequent failure of the components parts and increase the performance of the structure and machine life. It also enables, quality assurance engineers, reliability engineers, design engineers, etc. in the development of quality and efficient products. In this study, the static and dynamic analyses of mechanical and structural parts of a classical Angular Acceleration Apparatus which will be used in performing classical experiments in mechanics (kinematics and dynamics) of machines was designed and constructed. These type of analyses are performed with the purpose of estimating the behavior of the mechanical parts under specific operational conditions. The optimum safe and economical design of the machine shaft (s) were ascertained. The 3D model of the shafts were produced with inventor using absolute coordinates. The results of the commercial finite element analysis (FEA) were reported on the shafts stress, displacement and safety factor. The bearing strength check was seen to be positive when static equivalent load PO and dynamic equivalent load P were 1N each. From the simulation result, since the von mises stress value is not up to half of the yield strength of the material with a factor of safety of 15, the design of the shafts is considered safe.

Abstract- This paper talks about potential answers for the issue of information trade among components of a decentralized framework (simple/computerized actuators, sensors) through remote correspondence channels. The accompanying sorts of advances were picked to take care of the issue: ZigBee, LoRaWAN, Bluetooth, Wi-Fi. This paper shows the after effects of a relative investigation of the thought about answers for the issue, displays their primary focal points and comparison. The main focus is on emerging wireless technologies uses, frequency, range and at last conclude the most efficient technology.

Abstract- The aim of this research was to study the effectiveness of a chosen grass (plant) in the remediation of soil contaminated by crude oil. Lemon grass was used in this study to remediate the polluted soil because of its perceived ability to do so. Five wooden boxes were fabricated, and 150kg of soil were introduced to each of them. Four of the boxes were contaminated with different concentrations of crude oil, while two out of these four boxes were amended with cow dung. One of the boxes that served as control was neither contaminated nor amended. Lemon seeds were then planted in all the boxes and allowed to grow for the period of 12 weeks. Analysis were done at the beginning, during and after the plant growth in order to determine the rate of remediation, with particular interest in the TPH (total petroleum hydrocarbon), and few other heavy metals; copper, magnesium, aluminum. Two concentrations of contamination were artificially made (75g and 150g). The TPH, Pb, Zn and Ni contents of the 75g crude oil contaminated soil were 6.784ug/g, 0.485mg/kg, 0.867mg/kg and 0.030mg/kg respectively. It reduced to 6.356ug/g, 0.058mg/kg, 0.560mg/kg and 0.043mg/kg respectively after remediation. The TPHPb, Zn and Nicontents of the 150g crude oil contaminated soil were 9.109ug/g, 0.699mg/kg, 0.851mg/kg and 0.032mg/kg respectively. It reduced 7.713ug/g, 0.059mg/kg, 0.506mg/kg and 0.057mg/kg respectively after remediation. An interesting observation was that, amending the contaminated soil with cow dung gave a favourable result in remediating the contaminants. It took about 80months to remediate TPH to an acceptable level of 0.013ug/g, but over 150months to do the same for an unamended soil. This finding can be applicable in the estimation of time requirement for the remediation of crude oil polluted soil by concerned stake holders.
