Chartres Cathedral Notre Dame
1,779 wordsThe medieval Gothic cathedral was in many ways a civic building as well as a religious one.

A New Mobile Robot Navigation Algorithm
1,651 words... o virtual target switch applied in this method, robot is able to quit limit cycles and find a way out of the dead end. Even in loop shapes like in Fig. 7. a, still robot can find the opening at point C due to the fuzzy logic target seeking and obstacle avoidance behaviors. The algorithm shows its major weakness when it fails to reach the goal in such a concave and recursive U-shape environment shown in Fig. 7. b. This is because the robot encounters another local minimum at the location B an...

White Blood Cells Endoplasmic Reticulum
1,733 wordsThe studies of Robert Hooke 1665 into a plant material would allow the determination of a pore like regular structure surrounded by a wall of which he called cells this in itself unbeknownst to him, was the discovery of the fundamental unit of all living things. In 1838 a botanist called Schleiden derived the theory The basic unit of structure and function of all living organisms is the cell. Over 150 years later this can be regarded as one of the most familiar and important facts within the bio...

Strategic Management And Its Role In Public Sector
2,181 wordsStrategic management and its role in public sector Management is an integral part of the modern society's activity. It is connected to all fields of activity and that is why it is necessary to know as much as possible about its laws and specificity. In my paper I am going to discuss the basics of strategic management and its role in the public sector. Speaking about strategic management, it is necessary to specify some initial conceptual representations about management and management as a whole...

000 Years Ago Stone Tools
3,216 wordsTroublesome Questions In 1830 Mr. Rankin tied a rope around a projection out of a rock face in order to lower himself into Wellington Cave (Horton, 1980). The projection turned out to be the bone of a giant extinct marsupial. It was to be the first discovery of a great range of giant marsupials. Were these animals extinct? ? Horton (1980), describes how Leichhart believed that on his journeys to northern Australia he would find Diprotodon still roaming over the land. We now know that he was prob...

Short Term Goals Theory Of Evolution
1,604 wordsAccording to Darwin, the theory of natural selection would suggest that every individual seeks only to further their own goals at the expense of all others, as only those individual organisms that win the battle for resources get the chance to reproduce and pass on their genes, creating a new generation of individuals who are good at serving their own interests. Conversely, those who are good at serving the interests of others will not be rewarded, but will instead become extinct as those whom t...

Carbon Dioxide Methane Greenhouse Gases
2,776 wordsThe Global Warming Global Warming The relationship between humans and the state of the ecosystem is not only dependent upon how many people there are, but also upon what they do. When there were few people, the dominant factors controlling ecosystem state were the natural ones that have operated for millions of years. The human population has now grown so large that there are concerns that they have become a significant element in ecosystem dynamics. One of these concerns is the relationship bet...

Human Genome Project Dna Sequences
5,742 wordsLife as we know it is specified by genomes. Every organism possess a genome that contains the biological information needed to construct and maintain a living example of that organism. Most genomes, including those for all cellular lifeforms, are made of DNA (deoxyribonucleic acid) but a few viruses have RNA (ribonucleic acid) genomes. DNA and RNA are polymeric molecules made up of linear, unbranched chains of monomeric substances called nucleotides. Each nucleotide has three parts: a sugar, a p...
