HOW THE LAYERS WORK

When connecting to the internet, most people are only aware of the files or webpage that they are accessing. In a network, a series of processes occur over a set of hardware which makes data communication possible over long distances. With many companies trying to provide a system of interconnecting people from all over the world, there are the issues of making a device compatible, keeping the data secured, sending the file to the correct destination, making transfer of data possible from one platform or operating systems. In order to simplify connection, members of the International Organization for Standardization have provided guidelines for standard ...

Intrusion detection and prevention systems are the most reliable form of securing APT incidences and the overall security of the information infrastructure. This is because, unlike susceptibility and management systems and IT infrastructure support, they have the capacity to detect occurrences of APT and subsequently prevent damage to the computer systems. Firewalls are supposed to block illicit impound traffic, but in most instances, they do not succeed. Intrusion detection and prevention systems have the capability to detect and catch threats missed by the firewalls. Susceptibility management systems are used to identify, remediate and mitigate vulnerabilities in computer networks but ...

The periodic table of elements, by far, stands among the most notable discoveries in the history of chemistry. Nowadays, probably everyone who has ever heard about chemistry heard about the periodic table of elements. Its implications on the scientific world are so enormous that it has even leaked out to the general public and have become associated with the chemistry itself. This is not surprising considering the scientific strength of this instrument. Using the periodic table, many characteristic properties of the elements can be predicted and many phenomena can be explained. This discovery put so much scientific knowledge together, ...

Introduction

The Great Belt Fixed Link (Storebæltforbindelsen) is the fixed link connecting the islands of Zealand and Funen across the strait of Great Belt. The link is composed of three mega structures: a road suspension bridge (known as the East Bridge), a railway between Zealand and Sprogø, and a box girder bridge (known as the West Bridge) between Sprogø and Funen (Railway-Technology, n.d.). The link was purposely designed to replace the primary means of crossing the Great Belt (Transportation Research Board, 1995). Combined purpose and aesthetic perfection, this majestic link exhibits eccentric engineering skills and craftsmanship, a true man-made wonder.

The movement from sites of waste-disposal of contaminated groundwater is a problem faced by many cities in world. Solid and liquid waste dumped in landfills generates an atmosphere where inorganic and organic compounds present in the water or which are produced in the landfill become prone of entering the hydrological regime through movement. The movement of contaminants in water bodies through landfills is more distinct in temperate and humid climates as penetration of rainfall is moderate to high, and separation of leachate from the aquifers which are underlying for extended time periods becomes a complex process. In such areas, landfills gets ...

Abstract

In this paper, the author identifies at least three security-related threats and various recommendations how they can be addressed. So far, there were three man security threats that were identified. The first one was the outdated-ness of GFI’s front end system. The recommendation for this was for GFI to invest more in the creation of a team that would develop a dynamic, high quality, and more secure front end system, one that is suited to today’s speed and design standards. The second risk was the presumed use of a common cryptographic passphrase for all of its departments. ...

Introduction:

Corrosion refers to the partial and gradual dissolution of materials used in water treatment and supply systems, pumps, pipes, tanks and valves. In most circumstances, almost all water is corrosive and this may lead to structural failure, water leaks, capacity losses and deterioration of the microbial and chemical water quality (WHO 2011). The pipes used in water distribution are made of different materials such as plastic, metals (galvanized steel, copper, lead and iron), and even concrete. Pipes made from concrete and plastic tend to be corrosion resistant.
In piping systems, however, there are several water quality factors working singly ...

Introduction

There are environmental chemical processes which require light to react. These processes are called photochemical reactions. Photochemical reaction is commonly initiated due to the absorption of solar energy or light. When molecules absorb energy in the form of light, the atoms are converted in a transient excited state (Larson & Weber, 1994). This transition state or excited has completely different physical and chemical properties with the initial state of the molecule. The excited states also have more tendencies to react since they are considered stronger acids and stronger reductants that the initial state of the molecule. The excited state of ...
