Bacteria refer to the regnum of prokaryotes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan). For the current moment, it accounts for more than ten thousand kinds of bacteria. The bacterium is recognized as one of the most ancient of living organisms, arising about 3.9 – 3.5 billion years ago. Bacteria have the substantial variation in the ways of metamorphic and energetic metabolism. Thus, autotrophs can synthesize all necessary organic molecules from non-organic compounds, whereas heterotrophs demand active organic compounds to transform them. The biggest degree of heterotrophs belongs to intracellular parasites. They are called saprophytes (Sundararaj, Mudaliar, Anthoniraj, Kannan, Muthukaruppan) and can ...

Prison Design:

Prison design has to accommodate inmates by separating them with regards to the following two considerations: gender and degree of offenders. There can also be considerations on classifying and housing inmates according to their mental statuses. To successfully keep the society safe from medium criminals who are likely to get notorious, the prison will have two compartments that are designed differently. A radial design compartment will be used for inmates that show tendencies of risky behaviors. A campus design will serve for those inmates that are less harmful and expected to go back to the society (Waldron, 2014). Evidently, ...

Abstract

A rotary engine is one of the ancient internal-combustion engines ever used. These type of engines were designed with an odd number of cylinder per row in a radial configuration. The crack shaft remained stationary throughout the operation. One advantage of this kind of engine is that it is a simple engine that utilizes less moving components. On the other hand, a piston engine or a reciprocating engine is a heat engine that uses one or several reciprocating pistons. The piston engine converts pressure into a rotating motion. A piston engine has the capability to seal the gap in ...

Modern astronomy

There were four main contributors to modern astronomy: Sir Isaac Newton, Johannes Kepler, Galileo Galilei, and Tycho Brahe. Brahe advocated for the new standards for having a more precise observation even though he did not personally believe in the view of heliocentric. All of his contributions were huge for astronomy because he was able to create new instruments along with being able to calibrate them. He would check the accuracy of his instruments on a regular basis so it helped him to revolutionize instruments for astronomy. Kepler was an assistant for Brahe until he died in 1601. This helped ...

The Colosseum remains to be one of the largest amphitheaters of the ancient world. Located at east of the Roman forum, was originally known as the Flavian Amphitheatre after the dynastic name of the Emperor (Welch 24). It was commissioned around AD70-72 by Emperor Vespasian of the Flavian dynasty as a gift to the Roman people. The Colosseum was officially opened by Titus Vespasian, son and named it the Flavian Amphitheater where games were played in a hundred days including gladiator combat and wild animal fighting (Kuntz 45). This Roman structure remains to be one of the biggest Tourist ...

The paper discusses Kepler 186 exoplanetary system. It explains the technique of detecting Kepler 186 system, the structure, as well as its layout. Exoplanetary system denotes planets orbiting around a star other than the sun, or it is beyond the solar system (Charles, 2015).

Technique for Detecting Kepler 186

The method used to detect Kepler 186 is transit technique. A planet is described as transiting when it passes between its star and the planet Earth. As the planets of Kepler 186 pass between the Earth and the Kepler 186 star, the star's light is caused to dim, and this is detected by an instrument. ...

Measuring Heart Beats (ECG)

The heart rate of an individual has been defined as the number of times a heart beats every minute (Edlin and Golanty, 2016). When a heart beats, it pushes a volume of blood into the circulatory system. At some points in the circulatory system where the blood flows near the skin surface, one can feel blood flowing as a result of heartbeat. It is at these points where heart rate is measured. Usually, the heart rate of a person is measured at the carotid artery in the neck, radial artery located in the wrist just below the thumb, or ...

Questionnaire

<Institutional Affiliation> The main reason why theories are created is that they tend to explain a fact or a phenomena using suggested ideas that are based on principles. Landing to the moon is an activity that was practiced and witnessed by human beings. Therefore, no theory is needed whatsoever to explain the event. The speed to be measured is that of wind. The materials needed are: four cups whose shapes are hemispherical, and a spindle. The cups are attached to the spindle and the spindle vertically mounted on the ground, in such a way that the cups are ...

Introduction

The purpose of this experimental task was to investigate the possibility of using circular rods of different materials made from different materials and having different diameters as heat fins. Extend surfaces of heat fins allow for additional heating and cooling capacity in a cheap and passive way. The fins are intended for use in cooling a reactor by use of the surrounding air.

Introduction

Cylindrical pressure vessels have varied functions in our society today. When you drive into a filling station for gasoline, you encounter cylindrical pressure vessels as storage containments for the gasoline in underground burrows. Many of the people living in the countryside do not have cooking gas piped into their houses. They use cylindrical pressure vessels that contain liquefied petroleum gas. Containers of smaller sizes that serve different sizes in our households are cylindrical pressure services.

The fact is that cylindrical pressure vessels are very important, because of their varied functions. In underscoring the importance of cylindrical pressure vessels, the engineering ...

Fingerprint patterns are categorized into three main groups. These main patterns include loop pattern; whorl pattern; and arch pattern. Fingerprint patterns are used in forensic investigations of crimes. The fingerprint patterns are known to be unique to each individual; therefore, they help criminal investigators to identify criminals who are responsible for particular crimes (CSF, 2015). All individuals are required to submit their fingerprints to government authorities so that they can be used to identify them in future when need arises. Loop patterns have ridges that flow to one side, then loop around, and exit the fingerprint pattern from ...

Introduction

When the first crude telescopes grazed the vast space, the 17th century and astronomers such as Kepler and Galileo was already making discoveries of such as the moon craters, the rings of the planet Saturn, and the giant planet Jupiter. These discoveries paved the way for a more extensive exploration of the cosmos, which was ultimately revolutionized by the birth of the Hubble telescope. In April 1990, word’s most advanced space telescope named after the astronomer Edwin P. Hubble was launched at 353 miles above the earth’s surface with a mission to see deeper into space and beyond. The ...

How were Uranus's rings discovered?

William Herschel was the first observer to mention that Uranus has a ring system in 1789. It was only a speculation since the astronomers that time could not observe any rings around Uranus. The discovery of the Uranian ring system was observed almost 200 years later by James Elliot, Edward, Dunham, and Douglas Mink in 1977. The discovery of the ring system of Uranus was only an accident when they grabbed the opportunity to observe the atmosphere of the planet using the occultation of the star SAO 158687. In their observations, they found out that the star suddenly disappeared for five ...

Skin cancer or metastatic melanoma is one of the most aggressive types of cancer (Chin, Garraway, and Fisher, 2006). Understanding the physical or phenotypic alterations that occur in relation to skin cancer requires getting acquainted with its pathophysiology. Furthermore, learning the pathophysiology of metastatic melanoma can lead us to a better understanding of what may be most effective in curing the disease. Metastatic melanoma, causing approximately 13,000 deaths annually with a median overall survival (OS) period of 8 to 18 months, is considered as one of the most aggressive and prevalent types of cancer (Finn, Markovic, and Joseph, 2012). ...

Aircraft diesel engines

Aircraft diesel engines, commonly known as aero diesel engines, are a form of aircraft engine that began being built in the 1920s and 30s. These compression-ignition engines use diesel as the major fuel. The first diesel engines to be built were the Junkers Jumo 205 and the Packard air-cooled radial diesel engines that were used to fly aircrafts, they were not very successful. The Packard air-cooled radial diesel engine was the first diesel engine to fly an aircraft built in 1928 and was made in a similar air-cooled radial design used in the Wright and Pratt designs (Mollenhauer, Krister, & Tschöke, ...

Terrestrial Ecosystems Dynamic

Ecological systems are dynamic by nature and constantly feel the influence of climate variability. Since the structure and functioning of forest ecosystems are controlled by climatic factors through metabolic function, it may change in the future dynamics of forest restoration, growth, progress and growth of tree mortality, as well as the relationship of rocks. It is expected that climate change will be faster than the rate at which ecosystems can adapt and repair itself. Ecosystems of the North must first of all respond to possible global warming because of climate-driven ecosystem response reveals itself most clearly. At high ...

The nervous system can be divided into two groups: the central nervous system (CNS), which comprises of the brain the spinal cord, and the peripheral nervous system (PNS), which consists of the nerves. Nervous tissue consists of two types of cells: the nerve cells and supporting glial cells (or simply glia). Glia have different types and outnumber nerve cells. In the CNS, astrocytes provide structural support for neurons, regulate the extracellular concentrations of neurotransmitters and ions, and facilitate information transfer at synapses. Radial glia is critical in the development of the nervous system. Both astrocytes and radial glia can ...

Introduction

Cylindrical pressure vessels are often used for a variety of functions. Some of these functions include the storage of liquefied petroleum gas, either during transit or in the countryside where cooking gas is not piped into their houses. Cylindrical pressure vessels are also used in the storage of fuel in gas stations in underground bankers, from where the fuel is pumped into the vehicles at the filling point. Due to these varied functions, it is important to understand the dynamics of stress and pressure on these cylindrical tanks. This is very important, especially in ensuring the structural integrity of these ...

Introduction

Ultrasound can be defined as the use of high frequency sound waves (having a frequency above the range, which is audible to the normal human ear, i. e. varying between 20 Hz to 20,000 Hz) for changing the chemical properties of a substance (Ter Haar, 1999). Besides medical imaging, nowadays ultrasound has become an important therapy for the management of several orthopaedic clinical conditions (Ter Haar, 1999). Stimulation of the tissues beneath the skin’s surface using high frequency sound waves is likely to result in several therapeutic benefits. Tennis elbow (TE) or lateral humeral epicondylitis can be considered ...

Introduction

There is currently considerable debate about whether or not the U.S. space program should continue, particularly bearing in mind its huge costs in these times of austerity, when budgets everywhere are subject to severe constraints, from government level down to individual households. Also, because manned space exploration is not without risk (witness the Challenger and Columbia disasters in 1986 and 2003 respectively that cost the lives of all seven crew members in each case), many question whether those risks are justified; what does humanity gain from space travel that can cause the risks to be considered worthwhile? This research ...

Glioblastoma is referred to as the most cancerous type of astrocytic gliomas and the most commonly occurring chief brain cancer in adults. Due to the weak prognosis of glioblastoma, there is an urgent need for a better and profound understanding of disease pathogenesis. The article presents a demonstration of the fact that p53 deficiency is capable of cooperating with various mitogenic signalling pathways for inducing malignant glioma. As an example, it is not necessary to deactivate the ...

Ethical Issues in Marketing

Introduction Marketing is an essential function in any business. Marketing without ethics would result in unmoral business. Faced with conflicting pressures, marketing managers may make compromises that include unethical business. Often, such decisions can be rationalized: an inadequately tested product has to be brought to market quickly to beat competition and payments via a third party to organized crime may protect the company's employees as well as its distribution channels (Smith & Quelch, 1996)

Identify ethical issues in marketing

The four P's of marketing: product, price, promotion and placement involve several ethical issues. Product, for example, raises obvious concerns about product safety, but the social ...
