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 ...

In order to reduce the United States’ dependence on fossil-fuel energy resources, alternate sources of renewable must be investigated in order to reduce the country’s emission of greenhouse gas emissions which contribute to global warming. At the recent COP21 Climate Summit in Paris, the United States committed to a reduction of greenhouse gas emissions by 26-28 percent below its 2005 level. This includes reductions in methane, carbon dioxide, perfluorocarbons, sulfur hexafluoride, nitrogen trifluoride and nitrous oxide, all of which contribute to global warming . In order to achieve these targets, the United States will need to employ alternative sources ...

Vid30 complex participation in the degradation of CDC25 in yeast and their role in Ras/ cAMP/ PKA pathway

Background: Unicellular organisms such as Saccharomyces cerevisiae in its total life cycle is exposed to diverse and changing nutrient conditions. Thus, in order to survive and achieve a competitive advantage, it has adapted itself such that it not only uses the wide range of available nutrient sources but also the sources that are nutrient rich. It mainly uses fructose and glucose by rapidly fermenting to alcohol. In response to these nutrient conditions, the intracellular trafficking transcription and turnover of protein from nutrient transporters (e.g. Hxts) get regulated. Therefore, when the availability of the glucose increases, the expression of low- ...

Lab 2 – Water Quality and Contamination

Abstract In this lab, the water quality, contamination, and treatment were investigated. The ability of contaminants (oil, vinegar, and laundry detergent) to remain in the water after passing through the ground was examined. Also, the simple filtering procedure was assessed for its effectivity in purifying water contaminated with soil. The quality of tap water, Fiji, and Dasani bottled waters by the content of ammonia, chlorides, iron, phosphates, total alkalinity, total chlorine, total hardness, and pH was analyzed and compared. All of the studied contaminants proved to remain in the volume of water after passing through the soil; the proposed ...

Science fiction is nonexistent devoid of scientific and technological concepts. This essay aims at exploring how cautionary tales in science fiction make use of ideas rooted in science or technology. It focuses on four narratives and how their writers have incorporated scientific notions in creating admonitions. The four stories include Second Variety by Philip K. Dick, Slow Life by Michael Swanwick, Desertion by Clifford D. Simak, and Swarm by Bruce Sterling. These authors have used biological, chemical, physical, astronomical, or mechanical abstractions to warn the reader of impending danger in the narrative. In his narration, Philip K. Dick uses ...

Smoking is one of the most harmful habits dangerous to the health of not only smokers but also others. Currently, smoking has become a massive "epidemic" common among men, women and even children. The fact that smoking is harmful to health know everyone, but not all realize the true extent of its impact. Damage to health damage is delayed in time and not immediate, but gradual, usually after 10-20 years after the onset of smoking. Therefore, many smokers at first do not notice changes in their health status and believe that nothing will happen to them in the future, ...

Sudden Infant Death Syndrome (SIDS) is a sudden death of apparently healthy child aged up to 1 year as a result of cessation of breathing and heart failure, the cause of which cannot be established at the mortem expertise. Sometimes the syndrome is called as “death at the crib” or death for no reason. However, there are causes or risk factors for the development of this poorly studied phenomenon, and the parents, eliminating them from their life, can save the life and health of the child. SIDS is not a disease; it is a posthumous diagnosis that is exhibited ...

Identification of the Unknown Microorganisms

Unknown #1 Unknown #2 1. The identification of bacterial strains is a common practice in clinical and medical fields. The ubiquitously present microorganisms can be both, beneficial or harmful to the host they attack or inhabit. Since times, several biochemical characteristics have been identified for many bacteria that commonly are related to humans. These characteristics and morphology have been arranged in a systematic way to identify the targeted unknown microorganism along with ruling out the ones giving negative results for the characteristic tests. This way the search was narrowed down for each of the two unknown microorganisms. The Gram ...

Definition of a Controversial Punishment

The use of aromatic ammonia is one of the controversial punishment procedures that have been used to deal with aversive behaviors. This controversial treatment procedure was administered by a change agent when it was indicated, usually whenever the aversive behavior was noted by the change agent. The procedure involved opening a capsule containing the aromatic ammonia. The capsule was then waved under the nose of the individual with the problem behavior (Miltenberger, 2011). The rationale for the use of this controversial punishment procedure is that the individual with the problem behavior would learn to associate the pungent choking smell ...

Uses of Hydrogen in the Industry

Hydrogen is a colorless, odorless, flammable, non-toxic and flammable gas at atmospheric temperature. Due to its properties, hydrogen is one of the main starting factors used substance in chemical industries. It is the basic building block in manufacturing of ammonia (Ramachandran, & Raghu, 5). Hydrogen is used mainly in the manufacturing of two chemical components, which are ammonia and methanol. These chemical components are made industrially. The manufactured ammonia is used in fertilizer manufacturing industries while methanol is used in the manufacturing of polymers. Hydrogen is also used in oil refining industries for reforming oils to obtain a high-quality grade ...

The objective of this experiment was to prepare Beer-Lambert calibration curves for different forms of nitrogen and to determine the concentration of nitrate, nitrite, and ammonia ions in different water samples from the Biscayne Bay.

Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...

Section

Introduction The purpose of this lab was to find the amount and percentage of nickel present in an unknown compound using the "mole method." The unknown nickel compound was dissolved in water and treated with dimethylglyoxime and ammonia solutions to obtain the precipitate of known chemical composition (bis(dimethylglyoximo)nickel(II)), which then was weighed and using this data the amount and percentage of nickel in the initial compound were found. The insoluble Ni(DMG)2 complex is formed in two steps. First, the dimethylglyoxime reacts with hydroxide ion formed through the ammonia hydrolysis to produce dimethylglyoximate anion: C4H8N2O2( ...

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 ...
