Recommended: crisis of fossil fuels
In present day, it is necessary to reduce energy consumption, especially when fossil fuel is decreasing and energy price is growing. Over the last few decades, heat exchanger network synthesis (HENS) and optimization topic is the most-studied topic in process integration because of its task in the energy recovery. There are two different methods for the synthesis and optimization of HEN problems, including pinch analysis and mathematical programming.
Pinch technology is based on thermodynamic approaches which first introduced by Linnhoff and Hindmarsh in 1983 [1]. The important elements in Pinch Analysis are the performance of the design targets, the representation of the Composite Curves, and the decomposition problem into two regions, upper and below the pinch point [2]. In this technique, the minimum utility cost, the minimum number of matches and the minimum investment cost are acquired sequentially. The most significant parameter of pinch technology is the minimum approach temperature of the network ( ), which is an economic factor. The HEN obtained by the pinch design method at...

Dorianne Laux’s “Bird”
1108 Words | 3 PagesThroughout history, the story of womankind has evolved from struggles to achievements, while some aspects of the lives of women have never changed. Poet Dorianne Laux writes about the female condition, and women’s desire to be married and to have a home and children. She also seems to identify through her poetry with the idea that women tend to idealize the concept of marriage and settling down and she uses her poetry to reach out to the reader who may have similar idyllic views of marriage or the married lifestyle. Though Dorianne Laux’s poem “Bird” reads very simply, it is actually a metaphor for an aspect of this female condition.
The Calm Wendy Bird
2902 Words | 6 PagesPeter and Wendy written by J.M. Barrie is a classic tale of the adventures of the three young Darling siblings and Peter Pan, a magical boy from Neverland. Although this story originated as a novel, eventually several adaptations were created based on the story, which include Broadway plays, animated movies, television productions and more. Within the epic story of Peter Pan there is Wendy Darling, the eldest child of three, the only daughter of the Darling family and the leading lady in this tale. Wendy’s character begins the story dealing with a confrontation between her parents about growing up and acting her age, which shows that Wendy is not only childish but also restrictive to change, as she is already defensive to growing up. Wendy’s demands to remain with her brothers, and her parents refuse and ignore her demands, showing that Wendy has “no voice” or no control over her situation. This disconnection of communication between her and her parents’ shows there is a potential for her to be a “runaway” and eventually if so, experience “no recourse to anyone” (Franks, “Rural Runaways “ 5)

Barn Swallows
339 Words | 1 PagesJazz Stephens presented on Does Incubation Behavior Influence Nestling Telomere Length? And Egg Gross-Foster Experiment In Barn Swallows. The research measured effects of telomere length of barn swallow based on specific environmental criteria. In barn swallows, it is known that telomere length is associated with survival, reproductive growth, and success. The research team analyzed how incubated temperature affects telomere length. This experiment was done by two methodologies. The first, cross-foster design, which decoupled genetic environments to analyze how telomere changes in different environments. To test the temperature within the nest, a fake egg was placed within the nest the recorded the continuous temperature within the nest.
Summary Of Mother Hens Cluck
264 Words | 1 Pages“Mother Hens Cluck: Cell Phones Support Learning” has stronger evidence and reasons. In the article they have many logical reasons along with evidence. For example, the author used the reason “They have the right to access a simple tool that can help make things easier for them.”, this reason make sense because it helps explain her claim of “My students have the right to use their cell phones at school as much as I do”. The evidence she used for the first claim was “I use it all the time, for everything both professionally. Why should've to my students?” This evidence is very logical because it is proving that if the teacher can use a phone, the students should be able to as well. Another reason she used was “Many of my kids have challenges

The Importance Of Identity In A Bird In The House
1354 Words | 3 PagesIn A Bird in the House, Margaret Laurence is able to incorporate many themes and motifs into her stories such as, war, tragedy, religion, and faith. Another theme that is also shown throughout the book is identity, both national and individual identity.

Sometimes in life identity gets mixed up and can become a confusing aspect of life. People are a product of their environment, which is a factor in shaping identity. The protagonist in the book, Vanessa MacLeod, witnesses and experiences both types of identity. She sees the influence of the Canadian national identity in her Grandfather Connor, Scottish heritage in her Grandmother MacLeod, Irish heritage in her Uncle Dan, which ultimately influence Vanessa’s personal identity.

Backyard Chickens
649 Words | 2 PagesOne particularly warm evening last summer, I walked into my backyard to relax and enjoy some fresh air. Instead, I was greeted by the loud shriek of a chicken. We had an uninvited guest in our vegetable garden. Unfortunately, such chicken invasions are a common occurrence in many areas of Stockton, California. Throughout the United States, municipalities small and large are debating whether or not they should enact residential livestock ordinances, specifically in regards to poultry. Considering that they are often a public nuisance and pose a health risk, local officials should consider restricting the private ownership of chickens in heavily populated urban areas.
The Birdcage
1541 Words | 4 PagesWhat attracts us to the movie theatre on Friday nights? Is it the commercials we see? Or is it all the gossip we hear from friends and TV talk shows? Well for many, it is the critiques we read and hear almost every day. One who specializes in the professional evaluation and appreciation of literary or artistic works is a critic. The profession of movie criticism is one of much diversity. Reviews range anywhere from phenomenal to average. Not only are movies created for the entertainment and sheer pleasure of the audience, they create a market of jobs and open doors to the world of financial growth. The success of these films, whether they are tremendous or atrocious, is not only dependent of the actual film, but also upon the critic’s reviews. It is a form of assistant advertising, in addition to commercials and billboards. A movie review is composed of summaries, plots, controversial issues, perks, and detriments. They discuss the features of the movie and certain points that appeals to the critic. Not to forget that the sole purpose of writing these reviews is to persuade the reader to take on a pre-opinionated view of the film prior to viewing it. In addition, they hope the reader enjoys their style to further persuade them, as well as others, to persist in reading their reviews.

Chicken Farm Essay
710 Words | 2 PagesChicken farms need more government regulation for causing damage to both human and animal health and for being detrimental to the environment. Chicken farms produce large amounts of fecal matter that heavily contaminate waterways that are used for drinking. In the Delmarva Peninsula alone 3.2 billion pounds of raw waste, 13.8 million pounds of phosphorous, and 48.2 million pounds of nitrogen are released into the environment (Intensive Poultry Production).. These nutrients enter bodies of water causing eutrophication, which causes an explosion of algal blooms that die and require large amounts of oxygen to decompose. This increase in oxygen consumption creates ‘dead zones’ in many areas, most notably in the Gulf of Mexico, where there is not enough oxygen to sustain aquatic life.(Facts about Pollution from Livestock Farms). U.S. chicken producers use a total of 2.2 million pounds of the antibiotic arsenic compound, roxarsone (appositive), each year. Most of this compound passes through the chickens and into their excrement. The arsenic that is left in the excrement can leach into surface and groundwater supplies and become inorganic arsenic, a known carcinogen. This waste can also enter waterways, killing hundreds of fish. Inside the chicken farms, large amounts ammonia and dust particulates are released into the air, which can cause moderate to severe respiratory problems in humans.When waste pools are filled, the companies spray liquid waste into the air that mists and carries over to human populations that inhale these toxic gases and become ill. (Meat Production Wastes Natural Resources), Chicken farms also waste resources due to the fact that many crops, such as soybeans, are grown to be feed for livestock. Only 20% of the ...

The liquid stream exiting in the bottoms of the reflux drum is pumped at pressure of 3.3 bar for discharging pressure. The pump stream is separated in two streams. One stream is to feed to tray one of the column and the other one stream is cooled down to 38 0C in heat exchanger. Then, the cooled product stream is sent to storage.
Poultry Observation Essay
401 Words | 1 PagesThe first observations relate to appearance, attitude, and locomotion (Linares and Martin, 2010). These authors mention that, while active, healthy poultry stand holding their head high, wings folded close to their body, and legs extended directly under their body. Bracke and Hopster (2006), mentioned that some species-unspecific behaviors are very beneficial to health, performed by several species, such as playing, walking, limb stretching and turning, standing up and lying down normally. Poultry walking ability may be improved by perching and walking on ramps (Mench et al., 2001). According to Linares and Martin (2010), preening is the act of smoothing out or cleaning the feathers with the beak. It is a common behaviour performed in group
