Energy crisis and environmental pollution are highlighted to be one of the major global problems in the 21st century. For the past 200 years, human society has had a ravenous appetite for fossil fuels. The huge increase in human population and also the industrial revolution were the major sources of fossil fuel consumption. However it is becoming obvious that our dependence on fossil fuels is causing many problems that we are going to have to address. Therefore, our greatest challenge is to find means to reduce the extraction and combustion of fossil fuels. Fortunately, we have the potential to reduce the CO2 emission from fossil fuels combustion by converting them into renewable, carbon-neutral energy sources that provide the energy services now obtained from fossil fuels (1–3). In this context, a recent technology using microbial fuel cell (MFC) has been introduced to directly produce electrical current from waste streams based on the ability of particular bacteria, to bio-catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode, respectively (4–6) (Figure 1). The essential of this technology is the usage of a unique type of bacteria, anode respiring bacteria (ARB), which can typically respire electrons from the organic compounds to the anode surface and simultaneously protons (H+) liberate into electrolyte, lead to a negative anode potential. ARB are known only to utilize a few numbers of simple organic electron donors, such as acetate and H2 (7–9). The biodegradation of complex organic substrates in the anode of MFCs, like those present in a domestic wastewater, food processing wastewater, and landfill leachate, must take place through a cascade of reactions under strict anaerobic conditions, resul... ... middle of paper ... ...on pathways/kinetics of soluble carbohydrate and proteins when used as a sole electron donor or in mixture i.e., 100% carbohydrate, 100% protein, 50%:50% carbohydrate:protein,75%:25% carbohydrate:protein, and 25%:75% carbohydrate:protein. In order to achieve the objective, I will use different advanced analytical tools, such as (i) microbial ecology tool (such as pyrosequencing, quantitative polymerase chain reaction, and clone library), (ii) electrochemical analyses tools (such as cyclic voltammetry, linear sweep voltammetry, electrochemical impedance spectroscopy, and chronoamperometry), and (iii) chemical analyses tools (such as high-performance liquid chromatography, gas chromatography, ion chromatography, and chemical oxygen demand measurements) to predict the pathways of organic wastes fermentation as well as studying the hydrolysis and fermentation kinetics

The novel "A Farewell to Arms" should be classified as a historical romance. Many people in reading this book could interpret this to be a war novel, when in fact it was one of the great romance novels written in its time. When reading this book you notice how every important event of the war is overshadowed by the strong love story behind it.
Suddenly, it enters your thoughts and streams throughout your mind; you begin to think, you are in a stream of consciousness. You are in your own world of random words and sentences, amounting to nothing, and at times making all the sense in your world, a world that only exists within your mind. That is exactly how a stream of consciousness works, according to Charles Bohner and Dean Dougherty (1216). Ernest Hemingway himself traverses into three streams of consciousness of his own in order to develop Henry's character and the over all theme of A Farewell to Arms, war and love and all feelings in between. For instance, while Henry is not really required to go to war, he volunteers, without thinking of the consequences and horrors of war. However, along the way, he manages to encounter love, incur physical pain, and realize the horrors of war. And so, having to face a possible death while at the front, Henry finds himself in an extraordinary position. He is somewhere between life and death and while between these two extremes his experiences shapes him into a more mature character.
Death is often represented by traditional symbols ranging from the color black to the common tombstone. Besides these icons, other signs can stand for mortality including rain. In A Farewell to Arms, Ernest Hemingway associates rain with death many times. Although rain is not usually considered a symbol of death, the main character Fredric Henry discovers this natural occurrence is a personal theme he relates with death.
Ernest Hemingway once gave some advice to his fellow writer F. Scott Fitzgerald. If something in life hurts you, you should use it in your writing. In writing a Farewell to Arms, Hemingway followed his own advice. In many ways, Frederic Henry was a psychological parallel to Hemingway. The painful experiences of his own life, which were consciously and unconsciously placed in this novel, helped make it a major literary achievement.
Ernest Hemingway’s early life experiences, from hunting and fishing trips, to time spent during the Spanish Civil War and World War I, shaped his writing style and heavily influenced his literary works. Hemingway’s experiences in war provided him with the basis for two novels; For Whom the Bell Tolls and A Farewell to Arms. A trademark of Hemingway’s novels is his short, choppy writing style, which, with its calculated repetition allows readers to remember what has been said. Through his early life experiences as an ambulance driver and war reporter, Hemingway was able to understand the brutality of war and provide a basis for his novels.
A Farwell to Arms takes place during the late summer in Italy, in the midst of World War 1, and Italy at this time is at war with Germany and Austria. Frederic Henry, the narrator of the story as well as one of the primary characters, is an American serving in the Italian armed force as an ambulance driver. He finds himself falling profoundly in love with a gorgeous English nurse, Catherine Barkley. At the point when Frederic and Catherine meet, Catherine is in an entirely defenseless and vulnerable state due to the passing of her husband-to-be during a war in the previous year. This may be a reason for her falling in love too quickly with Frederic as an approach to free herself of the despair and sorrow that she is feeling. Henry gets wounded
Farewell to Arms The symbolism in “A Farewell to Arms” by Ernest Hemingway is vivid and dynamic, and in the novel, the rain and other factors, symbolize despair. The symbols are all presented in varying forms. Other symbolic factors include; lakes, rivers, snow, ice, mountains, plains, night, seasons, weather, Catherine’s hair, Frederic’s beard, officer stars, riding crop, the painted horse and the silhouette cutter. The symbolic concepts are: the baby, war, love, wounds, and the enemy. The different symbols have an effect on each character in the novel, in a special way.
Ernest Hemingway used his experiences from World War I to enhance the plot of A Farewell to Arms. Parallels can be drawn throughout the entire novel between Henry's and Hemingway's experiences. Both were Americans serving in the Italian army; both were wounded and went to Milan; both fell in love with a nurse. These many similarities, however, also contain slight differences. There is no real question that Hemingway based events in the novel off of his real experiences, but A Farewell to Arms is by no means an autobiography. The book does not focus on the experience of war. Instead, it is more focused on the after-effects. Minor changes to the events themselves make the novel unique, while the factual basis strengthens the plot with authentic feeling.
In the debate of traditional energy vs. renewable energy the clear winner is renewable energy. Renewable energy is vastly superior over traditional energy because it decreases dependence on foreign resources, produces no emissions, and is not limited in quantity. Opponents of renewable energy are likely to argue that this is not the case and that instead, traditional energy is better because it creates job growth, is reliable during all hours and climates, and comes with a lower cost. These advantages however are either misconstrued or hardly outweigh the long-term positive benefits of renewable energy.
By taking a Carbon Dioxide, rich substance and mixing it with a yeast, solution fermentation will occur, and then it could be determined if it is a good energy-producer. In this study glacatose, sucrose, glycine, glucose, and water were used to indicate how fast fermentation occurred. The overall result shows that monosaccharides in particular galactose and glucose were the best energy source for a cell.

There are indications in each of the novel’s five books that Ernest Hemingway meant A Farewell to Arms to be a testament against war. World War One was a cruel war with no winners; ”War is not won by victory” (47). Lieutenant Frederic Henry, the book’s hero and narrator, experiences the disillusionment, the hopelessness and the disaster of the war. But Henry also experiences a passionate love; a discrepancy that ironically further describes the meaninglessness and the frustration felt by the soldiers and the citizens.
The world that we live into today affords us the expectation that the flip a switch will turn the lights on. As populations increase and developing nations undergo dramatic economic growth, this energy demand will only continue to grow. The International Energy Agency (IEA) believes that “the world’s energy needs could be 50% higher in 2030 than they are today” (ElBaradei). Given this projected growth, it is necessary for world leaders must take action to secure the energy supply. Meaning that world leaders need to start seriously considering an alternative to non-renewable energy sources. “In 2012, the United States generated about 4,054 billion kilowatt-hours of electricity. About 68% of the electricity generated was from fossil fuel (coal, natural gas, and petroleum), with 37% attributed from coal” (U.S. Energy Information Administration). The fossil fuels that are used to supply over half of our country’s energy are in finite supply and are increasing in price to astronomical heights.
...so provided the reader with realistic descriptions of the warfront. Ernest Hemingway’s A Farewell to Arms realistically explores the inglorious and brutal truths of war, and idealistically analyzes the power of true love.
