Magnesium alloys are suitable biological material because of its favourable mechanical qualities, high biocompatibility, and biodegradability. However, it has poor corrosion resistance and has rapid dissolution in the corrosive environment which will weakens its mechanical characteristics. The surface characteristics of magnesium alloy must thus be changed using a suitable surface modification technology, such as micro arc oxidation (MAO). It was observed that characteristics of MAO coating can changed by varying electrical parameters like duty cycle, current density, type of power output, frequency, and processing time. It was noticed that when all other factors are held constant, duty cycle, processing time, and frequency primarily effect the coating's porosity, number of cracks and thickness, which in turn influences how well the coating performs. DC, AC, pulsed bipolar, and pulsed unipolar, are the four categories into which the current regimes are classified. It was found that, unipolar current mode MAO coatings found to be rough, highly porous, and vulnerable to microcracks due to stronger spark discharge. MAO coating produced in a bipolar current type of mode have larger pores but are more uniform in thickness and compact. It was noticed that the in-vitro cell assays showed cells L929 on the Ca-P coated Mg alloy to have considerably good adhesion, a high growth rate, and strong proliferation (p 0.05). In other words, the cytocompatibility was greatly enhanced by the Ca-P coating. It was discovered that the Ca-P coated Mg alloy improved cell responsiveness and encouraged early bone formation at the implant/bone interface by both conventional pathological examination and immunohistochemistry investigation. The Ca-P coating was found to be an effective method for raising the surface bioactivity of Mg alloy. It was also observed that the calcium phosphate coating deposited by MAO process improve surface biomineralization which is the main mechanism behind bioactivity. Functional groups that are present on surface engage electrostatically through calcium and phosphate ions from solutions to start the biomineralization process. Calcium phosphates have excellent biocompatibility and are quite comparable to the mineral makeup of bone. The current study aims to investigate the bioactivity of calcium phosphate coatings and the characteristics of magnesium and its alloys. © 2023 Trans Tech Publications Ltd, Switzerland.

Abstract- Motorcycles are one of the most popular types of automobiles worldwide. If our nation alone is taken into account, approximately 37 million two-wheelers are sold each year, and the number is growing day by the day. Motorcycles, mopeds, scooters (geared and non-geared), and other vehicles fall under this category. These cars are driven by people ranging in age from 18 to over 60. When travelling in such vehicles, a person must maintain a fixed posture for an extended period of time with little room for adjustment. Due to design and budgetary restrictions, only minor alterations may be made to meet the customer's needs. Motorbikes are prone to higher vibrations than four-wheelers due to uneven road conditions, vibrations caused by the vehicle itself, and less vibration dampening than four-wheelers. In addition to bad or unpleasant riding posture, vibration can cause discomfort, tension, and eventually pain in a specific muscle group or joint. This pain can be greatly reduced by using an ergonomically suited bike position.Keywords- Anthropometry, Motorbike, Riding Posture, Discomfort
