Introduction

The depletion of fossil fuels and the increased levels of vehicular that are being expressed across the world made the automobile companies to look for alternatives to the conventional internal combustible engines that run on petrol and diesel. One of the most important inventions in the field of automobile history is the hybrid engine technology. Hybrid cars combine the conventional petrol powered engines with the electric motors. A small petrol engine that is fit inside a hybrid car operates a dynamo that produces electricity (Barett nd). The electricity that produced will be in turn utilized for running the electric motor which ...

Iron

Iron has been known since prehistoric times. However, the beginning of its widespread use came much later, because iron rarely occurs in a pure form in nature and its preparation from ores became possible only at a certain level of technology. The importance of iron in modern technology is determined not only by its wide distribution in nature, but rather by a combination of valuable properties. It is plastic, easily forged in cold and hot conditions, amenable to rolling, stamping and drawing processes. Iron has a property to dissolve carbon and other elements – this is the basis for the ...

Introduction

The early 1900s were a period of significant change – aircraft, cars, transatlantic ocean liners – all these were coming into mainstream use, and owe their emergence to this period of technical advancement. Another lesser-remembered innovation of the time that captured the imagination of the people was the automat. The first example of automated fast food at a low price, the system consisted of a number of windows in which food was displayed. You put in a coin (initially a nickel or 5 cents later revised to a dime or 10 cents) and the window could be opened and the food taken. There were no waiters ...

Peace that people enjoy nowadays uninterrupted is, of course, not a new phenomenon. However, what is interesting is that the humanity has lived only several hundred years without warring for whatever reason could bring large armies face-to-face in a lethal confrontation for questionable reasons. Besides soldiers, the brute force of conflicts, the main tools of war have always been weapons indicating the state of technological advancement of nations, being the litmus paper and the benchmarks of progress. Thousands years ago, there was no such concept as a long-lasting peace, and the weaponry was a lot more different than it currently is, being used ...

Steel is an alloy of another metal, iron. In addition, it contains carbon components. The carbon content of steel metal varies between 0.002% and 2.1% according to their weight. In fact, it is the carbon component in the steel metal that makes it harder than mere pure iron. As such, these carbon atoms make it hard for any dislocations to occur in the iron crystal lattice preventing the lattice from sliding past each other. Notably, steel is the metal that is most widely used for construction purposes, as well as the most recycled metal on earth. It ranges from ...

One of the more striking essays in The New Kings of Nonfiction is Susan Orlean’s piece “The American Man, Age Ten.” In her narrative, Orlean vividly describes the inner mental workings of young Colin Duffy after having spent a couple of weeks with him. Her introduction utilizes the unique rhetorical device of using a ten-year-old’s voice, instead of a normal narrative voice. Instead of simply telling the reader about the boy’s life, she reveals it through his voice and also shares some of his own feelings and thoughts. Later, she includes narrative of times the two of them shared. ...

Introduction

Biomass is a biological material obtained from a living organism or a recently living organism. The word biomass is derived from two Greek words; bio meaning life, and maza meaning mass (Demirbas, “Fuels from Biomass” 43). Biomass means non-fossil and bio-decomposable organic matter (originating from plants, animals and microorganisms). The products, byproducts, residues and waste from agricultural processing, all constitute biomass. Bio-waste simply means non-fossil and biodegradable waste that is composed of organic matter. Bio-wastes include food and kitchen wastes, garden and park wastes, and wastes from food processing plants. Bio-waste is therefore an element of biomass.
Non-fossil wastes that are ...

Introduction

Waste biomass is usually in the form of manure, agricultural residues, municipal sewage sludge, municipal solid waste, and industrial bio-sludge which can be converted to animal feeds, alcohol fuels or industrial chemicals. There are various processes which are employed to convert this waste into the respective useful end products rather than being dumped away. The complexity of these processes depends on the kind of technologies being used. Conversions of waste biomass into renewable energy forms play a major role in reducing the dependence on crude oil and thus promote economic growth. The process of waste biomass conversion to useful products ...
