Introduction

The cost of manufacturing ammonia using the Haber process plant constitutes the following components: the cost of energy, raw materials, equipment, labor and sparking substances (catalysts). Energy (gas or electricity) costs are incurred to maintain the temperature of the reaction. The Harber process is operated at very high temperatures, and pressures thus higher costs of energy are incurred. Some of the raw materials consumed in the Haber process such as nitrogen and hydrogen are recovered at the end of the process. The recovered materials are recycled back to the system to reduce the cost of raw materials. Starting and ...

Introduction

Reduction reactions are very important in chemistry as they are effective processes for synthesizing new compounds from existing ones. In organic chemistry, a compound is said to be reduced if it acquires new hydrogen. There are diverse reagents for carrying our reduction reactions. Two of these are sodium borohydride (NaBH4) and lithium aluminum hydride (LiAlH4) - the latter is a more powerful reducing agent compared to the former. In this experiment, NaBH4 was used to reduce p-Nitrobenzaldehyde to form p-Nitrobenzyl alcohol. NaBH4was used over LiAlH4 in this experiment, because LiAlH4 would also reduce the nitro group of the aldehyde.

Experimental:

Introduction

Fire in Goafs (mines) is considered to be a potential environmental and health risk throughout the globe. Although, plenty of conventional fire extinguishing methods has been proposed in the past, yet they contain side effects. The authors in propose a novel fire management system using expansion form for fighting with fire at the top of goafs. The system contains a jet device for adding foaming agent produced by foam generator. The foam is powered by water pressure and compressed gas that are intrinsically safe for operating in mines. The expansion foam propels itself upwards to extinguish fire at the ...

Dreams are a profound mystery that largely went unexplained throughout the majority of human history until Sigmund Freud tried tangling with them. One of his assertions was that if a person feels guilt for any reason but then represses that guilt so that he no longer senses it on a conscious level, it will emerge on an unconscious level, such as through insanity or nightmares. It is possible to repress guilt, of course, so that it no longer has much to do with us on a day-to-day level, but it does not leave. It simply lurks in a different ...

Invented and patented by Thomas Edison in 1879, the incandescent bulb comprises of a wired filament placed inside a glass bulb (“The History”). When electricity is provided to the filament, it heats up thereby making the bulb glow and emit light (“Incandescent, LED”). The wired filament of the incandescent bulb was initially made using carbon obtained from a cotton thread that was uncoated. This filament gave the bulb a lifespan of just 14.5 hours. Later, the carbon filament was made using bamboo, which gave the bulb a longer lifespan of up to 1200 hours (“The History”). Much later, in ...

Description of the best fire detection equipment to be installed in the Electrical Switchgear Room, Flammable Liquids Room and the Office. The best fire detection system to be installed in the Electrical Switchgear Room is the photoelectric smoke detector (FM Global, 2). This is because cables which are necessary in the Electrical Switchgear Room are mostly insulated with combustible materials which would invariably generate smoke as they burn in the event of a fire (FM Global 1). This type of smoke from such smoldering fires (characteristic of burning plastic/insulating) according to the NFPA can most effectively be detected by ...

INTRODUCTION

My research will examine techniques that optimize financial, environmental, quality, and energy aspects of contemporary architecture. The work of Norman Foster and Partners will be considered in detail. This award-winning firm has many high-profile projects concerned with energy efficacy. I will examine Foster designed buildings in order to better understand strategies for maximizing savings and encasing ecological conservation through passive solar design.

Principles of Passive Solar Building Design

Passive Heating is designed with Solar Geometry; solar geometry uses the natural path of the sun across the sky in both the summer and the winter to reduce the need for cooling by air conditioning, the provide ...

Modernity in Virginia Woolf’s Writings

One of the most important of Virginia Woolf’s writings, which is theorized on the concept of modernity is Mrs. Dalloway. Written in 1953, this particular work of Woolf if part of the contemporary literature. The overall theme, setting, and narration in this particular work were all constructed upon principles of modernism. The primary aim of Woolf was to diverge from the conventional thought processes that existed in the society prior to the First World War as the aftermath of the war brought in a dramatic degree of change in the way the world is perceived by people. The ...
