CT scanning is a medical process that uses accurate x-rays in medical imaging of organs inside the body. The process is fast, accurate and can detect internal injuries, diseases, and hemorrhage. CT scanning involves producing images in different planes including 3-D, which can then be observed on a computer screen, in print or copied to a DVD. This method is more favorable than traditional x-rays because it is more detailed and can be easily manipulated by a physician. CT scanning provides excellent details of internal body organs, bones, soft body tissues, and blood vessels. CT scans can diagnose conditions ...

Inside, the building is divided into two parts for safety reasons. As ...

Abstract

Materials exhibit different chemical and mechanical properties such as strength and durability. Combining different materials to form a material composite enhances their individual properties in different measures. In this experiment, the mechanical strength of composite sandwich structures was investigated through bending. Four samples were investigated for their properties on bending and strength. Three of the four polystyrene beams were reinforced with paper while the fourth beam was investigated without paper reinforcement. One of the beams was bonded with construction paper on one side; the next bema was bonded with construction paper on both sides while the third beam was ...

Viable basement and foundation scheme

Given that the proposed structure is a steel building, the foundations will be driven piles supplemented by ground beams also driven into the basement walls. On the other hand, the basement will be built from steel sheets since these are highly cost effective and most ideal to retain the structure. In such a case, a viable foundation scheme is proposed.

Foundation scheme and justification.

First of all, a pile foundation is essential since it is capable of supporting heavy concentrated loads compared to spread footings. End-bearing driven piles are preferred instead of friction piles since they will be pushed into the ground using ...

Radiology, without which it is impossible to imagine modern medicine, was born with the discovery of the penetrating radiation made by German physicist Roentgen. This industry has largely contributed to the development of medical diagnostics. As any other industry, its development was revolutionary and has been infuenced by modern technologies. Today, X-ray diagnostics gets a new development. Using age-old experience of traditional radiographic techniques and armed with new digital technologies, X-ray diagnostics is still a leader in diagnostic medicine. In 1894 German physicist Roentgen (1845 - 1923) launched an experimental study of electrical discharges in the glass vacuum tubes. ...

Abstract

The uses of radiation revolutionized medicine when experimentation on its potential applications begun. X-Ray technology, discovered by Wilhem Roentgen, is currently used as a common tool for diagnostics; Henri Becquerel, Marie Curie and Pierre Curie dedicated themselves to further investigations in the field, discovering additional radioactive materials (polonium and radium); radiation therapy is a popular treatment for cancer. This paper analyzes the historical background behind these two applications of radiation in the medical field. Moreover, the different types of radiotherapy are described (external-beam radiation therapy, internal radiation therapy). The concept of radiation homeostasis, which is the notion that low-dose ...

It also identifies the different parts of Plant organs and their functions such as cell organelles, parts of a land plant, and epidermal cells. A microscope is an important tool for examination of biological specimens, including cell’s internal structures called organelle and is important in magnifying the focused area. Plants are classified into four main groups, namely, ferns, mosses, flowering and confers. This paper finds that ...

It is evident, and all would agree, that the house should be strong, durable, built quickly and at a relatively inexpensive cost. In most cases, disputes begin on the choice of building materials. Which would be stronger, thermal insulated, warmer – wood, brick, concrete, or polymer-based materials? Which of them are considered environmentally friendly and which are not? Until recently, metal, steel in particular was not part of the discussion on the material for the construction of the frame of an individual house. However, the development of energy-efficient technology, the translucent structures based on steel beams are built today even ...

Introduction

Civil engineering and its related fields are very diverse and entail both structural design and architectural work. Structural engineering as we can deduct from the term ‘structure’ deals with the physical components of a given design. For example, in the house construction process, the structural engineer considers all the aspects of materials to be used and consults with the architect to ensure the durability of the home. On the other hand, architectural engineering refers to the technology of incorporating the basic functional aspects of a given design to make sure that an ambient environment has been created. My journey ...

Liver is the largest ‘gland’ of the digestive system. It is located right under the dome of the diaphragm, coated by the capsule. It is distinguished the liver’s convex upper surface adjacent to the diaphragm, and a lower, downwardly facing and in contact with the back and abdominal organs. On the part of the upper surface of the liver it can be seen its right and left lobes, the boundary of which is the crescent liver ligament. To the lower surface of the right lobe there is a gallbladder, close to the deep groove of the liver there ...

Abstract

The experiment involved the investigation of the young’s modulus of different beams made from different materials. The beams that were used for the test were steel, aluminum and timber. The experiment involved placing of the beams on the measurement machine shown below and addition of loads at the center of the beam. The loads were then varied across the beams while investigating the relationship that existed between the beams when different loads were added. The height, width, and the respective deflections were therefore recorded for analysis. The dial gauge was used to measure the deflection of the beam ...

Trans-World Flight Center, John F. Kennedy Airport (1956-1962)

Opened in 1962, the Trans World Flight Center of the John F. Kennedy Airport is one of the finest structures belonging to the Organic Modern Period that emerged in the mid-20th century.1 What makes this style truly remarkable was the fact that it is based on neo-futuristic designs as well as embodying strict adherence to geometrical proportions, the creation of functional space for the passengers, aircraft, employees, and maintaining harmonious interaction of the structure in its environment.2 The structure was designed by Eero Saarinen, a notable architect and one of the prolific figures that proposed designing the concept of ...

DEFLECTION OF BEAMSIntroduction

Any kind of modern day construction makes use of a component called structural beam, or beam. A beam helps in adding strength of any design or structure. Generally manufactured using steel, wood, or concrete, it is commonly used for spanning any open element of a structure. In any design work based on iron, steel I beam is the most commonly used one. On the other hand, home-based constructions generally make use of wooden beams. When steel I beam is encased within concrete, it forms a concrete beam and is typically used in the construction of heavy structures, such as ...

Abstract

In this experiment, the young modulus of three beams was investigated these were steel, aluminum and timber. The beams were placed and the deflections values upon addition of various loads at the Centre of the beam taken. There was a variation of the loads across the beam to investigate thee relationship that existed between the loads, the span width, height, and deflections. Measurement of the deflection was therefore done through the dial gauge with three sets of measurements being taken and the average calculated. Different beams were used to enable elaborate comparison of the coefficient of elasticity. Measurement of ...

Abstract

The aim of this experiment was to determine the relationship between the Young’s Modulus and the deflection of a beam. Since different materials have different values of Young’s Modulus, the students selected three different materials for the experiment. In this case, the materials used include timber, aluminium, and steel. All the materials were identical in terms of the dimensions such as width and length. The each beam of the three materials was subjected to some magnitude of force at the centre and deflection measured. Data concerning the magnitude of load and the corresponding defection were then gathered ...

The architecture of the early 20th century relied heavily on the introduction of new materials which led to the existence of new styles that rejected the notion of social hierarchy and religious affiliation. During this period, the buildings created within the early phase of modernization became so diverse and eccentric yet it was due to this nature that allowed architects to apply all the scientific knowledge in creating functional structures rather than buildings based on the designer's viewpoint. What separates the style of the 20th century from its predecessors was their openness in terms of exploring new materials especially ...

Abstract

In this paper, we will discuss and describe the application of mathematics in architecture. Starting from the explanation of the meaning of architecture, we will consider the relationship between architecture and mathematics since ancient times. One of the most significant contribution of mathematics in architecture is strengthening the building constructions. This property can be traced in many ancient structures (for example, the Parthenon, the Colosseum, Stonehenge). The evolution of the types of construction design was tightly related to mathematics. In our research, we will discuss various designs, such as pyramidal, post-and-lintel and carcass construction systems. Special attention will be ...

In the summer of 1947, something in the sky crash-landed near Roswell, New Mexico. Several locals claimed that there were horrific thunderstorms that summer, and when they were out in the location of the crash, they found metal debris strewn across a wide area approximately three-quarters of a mile long. One of the men, Mack Brazel, took some of metal pieces back to his house and he and the neighbors examined the material. Brazel and his neighbors, the Proctors speculated that the metal could be from a crashed spacecraft. That summer over New Mexico there had been quite a ...

Abstract

The following summary discusses the cooling techniques of atomic vapor in several different ways. Additionally, it tends to relate the evolution of experiments that are used in studying shallow layered fluids. Starting with the atomic condensates, the method is known as trapping. However, it exists in many ways from the laser system to the Bose-Einstein methods. The methods of cooling are different due to the evolutionary progress made by science. The use of laser beams includes the study of light forces on atoms which lead to either an absorption or emission of a photon. While the contraction of matter ...
