Volkswagen Ethics

The Automobile industry like many others prides itself in its quality manufacturing processes, adherence to compliance norms, innovation and customer satisfaction. However, over the last few decades the industry is plagued with myriad cases of ethical misdemeanors. Some of the unethical behavior probably arises from pressures of business, profits, shareholder value and competition (Bazerman and Tenbrunsel, 2011). In some cases, leaders turn a blind eye to unethical practices. In one of the older cases from the 1970s, ...

Fuel Cell Technologies in Passenger Cars

Fuel Cell Technology The last decade is characterized by the rapid development of research activity in the field of fuel cells, thus, creating the conditions for their uptake in electric systems. The basic fuel cells’ operating principle has been known for 150 years. However, a variety of technical and financial problems had kept them on the margins of technological applications (Brandon & Hart, 1999). The basic difference between a fuel cell and batteries is that while batteries store energy, fuel cells directly convert a fuel’s chemical energy into electricity by an electrochemical reaction (i.e. Without requiring combustion or movement ...

Literature Review

Abstract Innovations and modifications that produce cost reductions and enhance performance have driven the evolution of the classic solid rocket and the liquid bipropellant rocket into hybrid models that integrate the predominant solid and liquid model features into more sensical, more economical fabrications of design. The commercial spacecraft demands for aerospace propulsion have also evolved to include a market for environmentally sustainable hybrid rocket engines that has yet to fully mature to the Technology Readiness Level (TRL). Numerical modeling has been used as a tool to test the feasibility of new solid fuel types. ABS has been considered as ...

Volkswagen Scandal

Dear XYZ, In response to the work assigned for preparing a report on Volkswagen emission controversy, please find enclosed the detailed internal report containing my findings and recommendations pertaining to the issue. As I found, the company is going through the tough time when it is facing actions from the regulators and other agencies for violating the emission norms of the different countries. Also, there is a big blow to credibility in the eyes of customers. Concerted efforts of all the stakeholders are required to tide over the crisis. Based on the sources I referred to, the report goes ...

According to EPA (2016), environmental management involves the development of systems aimed at reducing environmental impacts of various activities. In the Brundtland commission report (WCED), sustainable development has been described as development aimed at meeting the current needs of the present generation. However, as the current generation focuses on meeting their own needs, their activities should not compromise the capability of future generations to also meet their own needs. Available evidence suggests that the future generation would have challenges meeting their own needs if the current generation fails to adopt sustainable practices. The sustainable development incorporates the triple line: ...

Every commercial aircraft is fundamentally designed for safety, passenger acceptance, fuel efficiency and airport compatibility among other important features. Numerous challenges face all current passenger aircrafts, for instance the conventional wing consists of a number of moving parts which increase the weight of the plane and are difficult to adjust and maintain. The current control surfaces also increase turbulence and drag since the smooth flow of air is disrupted, and the aircraft cannot adapt to different flight stages and conditions. Design architectures such as the vertical and horizontal stabilizer surfaces increase the overall drag of the plane, for example, the ...

Introduction

Quality of air is a determinant in the quality of life, indoor air is important as people spend on average 80-90% of their lives in door (WHO, 2007). Indoor air quality began a long time but only been a health concern decades ago when awareness of contaminants presented in the air. The problem begins when the construction of building are highly insulated to conserve energy, which caused a trap to air intoxicants inside the building (E. Willard, 2005). This causes the exchange of outdoor to indoor to lessen and therefore the indoor air pollution builds up.

Indoor air quality is a complex issue as ...
