Ultraviolet (UV) light refers to the electromagnetic radiation that possess a shorter wavelength compared to the visible light and longer than that of the x-rays. The wavelength of UV light ranges from 400 nm to 100 nm (NASA, 2013). This corresponds to photon energies that range from 3 to 4 eV. The UV light got its name from the fact that the spectrum that is formed by the light has electromagnetic waves that have a frequency greater that the ones that are identified by humans as violet. The frequencies are not visible to humans other than those who have a condition called ...

“Are We Doing Enough to Protect the Earth from Asteroid and Comet Impacts?”

Even though efforts are underway, much still need to be done to protect the earth from asteroid and comet impacts. The study of the impacts of asteroids and comets only began in 1980, and since then, only the U.S. government has funded the studies. Other governments have only expressed their concerns about the hazards of the asteroids and comets (especially those close to the earth, often referred to as Near Earth Objects or NEOs), but none has funded the surveys or the research.
Currently, astronomers are surveying the skies regularly to see if there are some large objects ...

Introduction
Columbia accident investigation board is an organ that was chosen by the NASA to find out the accident involved by the space shuttle Columbia. According to the investigation, it was found out that the accident occurred as a result of technical problems. It was found that foam insulating the tank broke away and damaged one of the wings. The board further investigates about the root cause of the technical hitch. It was realized that there had been several cases of accident occurring under the same circumstances. However, the management has been reluctant in addressing the issue because most ...

1086F Origin and Geology of the Solar System

- Introduction
An exoplanet is a term used to describe a planet that is located outside the solar system that includes the Earth (exoplanet, 2013). Astronomer Peter van Kamp made the first announcement of the discovery of an exoplanet in 1963, however, that discovery failed to hold up over time and now has been conclusively disproved (Matson, 2013). The first exoplanet discovery that has stood the test of time was the discovery of two bodies orbiting a neutron star in a system named PSR 1257+12 (Wolszczan and Frail, 1992). Wolszczan and Frail calculated that the masses of these exoplanets would be ...

1. Introduction
The engineers are also called as the creator of the new technology, certainly engineers focuses to create a product based on the user needs. The engineers try to satisfy the user. There are some engineering excellent creations like ATM machine, Vehicle, Mobile phones etc, which are still used by more users. The first duty of the engineers while designing a product is considering safety to the public while using their product. The knowledgeable engineer always consider the safeness of the product while he or she is designing the equipment, but there are some engineering failure in ...

Rockets and newton’s laws of motion

Rockets and newton’s laws of motion

Introduction.

The movement of a rocket from the surface of the Earth to an arrival on the Moon can be clarified and depicted by physical principals found more than three hundred years back by Sir Isaac Newton. He worked in numerous regions of math and material science. He added to the speculations of attractive energy in 1666, when he was just twenty three years of age (Loeschnig & Zweifel, 1999). Newton's first law expresses that each item stays very still or in uniform movement in a straight line unless constrained to change its state by the ...

Mechanism of hydraulic systems in aircrafts

Hydraulic system in aircrafts consists of a system in which liquid under pressure is utilized to transmit energy. The power from the engine is converted by the hydraulic systems to hydraulic power. Several hydraulic systems existing in an aircraft include the landing gear, brakes doors and control boosters. According to Roskam (2000), some of the components that are part of the hydraulic system include hydraulic fluid reservoir, accumulators, hydraulic pumps, valves, and lines for distribution and controls located in the cockpit to operate the different functions of the hydraulic system.
The hydraulic system has an actuating cylinder that functions ...

Evolution of Human Factors in Crew Resource Management

Executive Summary

Most aspects of aviation have radically changed since the advent of the first aircrafts in the late 19th century. With increasing technology in flight development, crew management protocols have also been changing ever since (Helmreich, Merritt, & Wilhelm, 1999. pp23-24). However, the last 50 years has witnessed the greatest improvement in the way crew management is carried out in various aviation settings. This paper shall determine the evolution of crew resource management considering all the factors that have changed in one way or the other, culminating into the modern aviation management protocols. Validation of the crew resource ...

A volcano is a crack or opening in the Earth’s crust, which erupts, magma, lava and many hot gases present the Earth internal structure. A volcano is actually formed when the magma erupts from the Earth, and it forms a mountain on its surface, which becomes the crevice through which lava erupts every time. The Earth’s crust is about a few hundred kilometers thick below the Earth’s surface. It is made up of tectonic plates that are found to float upon magma, which is liquefied, ...

Contribution: He holds the chair of University Professor at the University of Pittsburgh and is a member of the National Academy of Engineering USA. He wrote a paper on “Decision making with the analytic hierarchy process”
Details: There are many intangibles involved in decision making which need to be traded off. In order to do that, it is important to measure and evaluate the intangibles along with the tangibles. Thomas L. Saaty, who is internationally recognized for his decision-making process, called as the AHP (Analytical Hierarchy Process). It is a concept of measurement through pairwise comparisons and focuses on the opinion ...

Introduction

Human beings started the space missions in mid 20th century as they sought to understand what makes up the earth and other parts of the solar system. The space missions have been mostly concerned with the exploration of the space components and their environs. This has helped astronomers as they seek out to know what the solar system is composed of together with what they can do to these processes.
The first space exploration to be analyzed is the Mercury which took place from the 20th February 1962. Several astronauts used the Atlas rocket to make orbits around ...
