Introduction

Robert Smithson examines the protocols of the standard modern aesthetics. His arguments point to the development of a limitlessness approach into art inspection, whereby art may exist in the mind of the observer in an abstract fashion. He sees the natural world as the foundation on which the ideological characters of people’s concepts emerge. Smithson indicates that boundaries and protocols do not exist for all artists in the same way. The mind of the artists is as vast and abstract as the earth’s surface. In earth projects, both real and fictional elements interact and trade places. According to ...

Executive summary

In understanding cost and pricing dynamics in relation to profitability, at least four issues face the cost accountant in tracing product or service costs, the value of which will be used as an essential input in pricing decisions. These are complexity, accuracy, ease of estimation, and time. Joint cost allocation is an example of a complex cost tracing due to inevitable data gaps. Sunk costs exemplify a type of cost the accountants normally consider as marginal and, therefore, may be ignored in the cost trace. Opportunity costs also possess a unique characteristic in its “potentiality” by nature, although quantifiable based on ...

ABSTRACT

In the vibrating beam experiment, an aluminum cantilever beam was made to vibrate. An accelerometer transducer was used to convert the mechanical vibrations into a signal that was fed into an oscilloscope via a power supply. The oscilloscope mapped the signal into a sine curve and displayed it on the screen. The oscillations’ decay curve was studied and the beam’s damping ratio was determined. The decay curve’s logarithmic decrement was used to determine the beam’s damping ratio and its natural frequency. The beam’s damping ratio was observed to be underdamped at a damping ratio of 0.0066.

Dissolved Oxygen

INTRODUCTION Dissolved oxygen is a useful parameter used to determine the level of effluent in waste water treatment. Living organisms in water bodies require oxygen to break down organic matter. These organisms consume the dissolved oxygen in water and give out carbon dioxide. Oxygen does not readily dissolve in water and gets depleted quickly by increased micro-organism activity. To maintain optimal oxygen levels in a water body, the oxygen replenishing rate from the air should be equal to dissolved oxygen use by micro-organism in the water. A curve drawn to represent dissolved oxygen levels down a stream from a point of effluent ...
