Utilization of Plastic Waste Production of Hollow Blocks and Bricks

The objective of this IP is to prove that plastics can be recycled into reusable hollow blocks/bricks and help the environment by lessening plastic waste. In this experiment, plastics were cut into small pieces to use them in bricks/hollow blocks.The objective of this project is to help prevent water pollution that causes flood, by collecting and using plastic wrappers in making hollow blocks and bricks. Plastic materials are commonly used in or daily lives. Plastic bags, wrappers, and other related products were introduced to substitute paper products. But now different problem arise because of the use of these materials. Land and water pollution are most common. Those plastic materials are improperly dumbed cause flood because plastic waste takes years to decompose. So one way to lessen those problems is to utilize those plastic waste products, instead of dumping them, and make them reusable. In this experiment we will demonstrate how plastic waste can be used in making hollow bloc ks and bricks.The product can only be used as decorative block and is not intended for building houses and the likes. Every day, we throw away large quantities of polymer in the form of plastic bottles, cartons, and yogurt pots. Experts estimate that 25 percent of polymer waste is unsuitable for recycling for three main reasons; it is economically unprofitable; and it is too dirty. Now, researchers from the Latvian Technological Center and the Institute of Polymer Mechanics at the University of Latvia have come up with a solution. Working with Hormigones Uniland, a Spanish cement company, the researchers have succeeded in turning thermoplastic polymer waste into a binding substance that could be mixed with other materials, like sand, to generate cement-free polymer concrete goods.â€Å"The polymer concrete bricks look like ordinary bricks made from cement,† says Dr. Juris Balodis, project manager at the Latvian Technological Centre. However, he points out that the polymer con crete absorbs less water† so it is very good for resisting temperature variations like freezing.† Both the European market and consumers are expected to benefit from this material, which can work well in a wide range of products,  including street furniture and street curbs. Dr. Balodis and his team are now researching how to accelerate the production of bricks. The current rate is three bricks per minute, but the team wants to increase production to between 30 and 60 bricks per minute.METHODOLOGYMaterials Plastic waste wrappers Cement Red cement Wafer PVC pipes Molder Basin Measuring cup StrainerPROCEDUREThe waste plastic materials were collected and cut into tiny pieces. A basin was prepared for the cement and plastic wrappers. Thirteen cups cement and 13 cups of plastic wrappers were poured into the basin and mixed well. A molder was prepared for the hollow blocks. Eleven cups of plastic wrappers and 11 cups of cement were mixed thoroughly. The mixture was then pour ed into the molder and allowed to dry for two days to ensure that it is firm before it is removed from the molder. For the bricks, two cups of cement, one cup of plastic wrappers, and one cup of red cement were mixed thoroughly. The mixture was then poured into the molder and allowed to dry for at least two days.Results and DiscussionThe following are the observations made on the resulting products: Ordinary Hollow Blocks†¢Long †¢Somewhat Brittle †¢Thick †¢Grayish White Ordinary Bricks †¢Hard †¢Thick †¢Wide †¢Easily Breaks †¢Brown Hollow Blocks with Plastic †¢Smaller in Size †¢More Durable †¢Thicker †¢Dirty White Bricks with Plastic †¢Harder †¢Thinner †¢Wider †¢Durable †¢Light RedConclusionWe therefore conclude that plastic waste can be used in the production of hollow blocks and bricks.Suggestion and RecommendationsThe Researchers recommend collecting plastic wrappers as well as other plastic waste and use or turn them into alternative products to and help the environment. This project can prove useful in homes. Those plastic wastes can be reused in a more profitable way. Lesser waste means lesser pollution in the environment.

DESCRIPTIVE ESSAY

DESCRIPTIVE ESSAY As we all know that an essay is a form of short piece of writing that is created to share authors point of view. An essay is a pedagogical tool used to teach and to improve students writing skills. One of the most common and widely-used essays is descriptive essay. Descriptive essay can be categorized as the type of academic writing that majorly focused on picking up of sensory sort of details. Â  Sensory details mean an authors perception like getting and understanding the sensory information. Sensory information is obtained through physiological capabilities of the body and processed through mind perception. By describing your own sensory perception in the descriptive essay, you are appealing to the readers. You major goal is to draw in the reader’s attention through his emotional, physical and intellectual involvement. While writing your descriptive essay, consider your audience, focus on getting the strong impression, use variety of linguistic descriptive tools to receive audience reaction. DESCRIPTIVE ESSAY Writing descriptive essay is an academic skill that requires some practice. The major knowledge about descriptive essay is actual knowing exactly what this type of writing requires. Initially, descriptive type of essay implies the excessive use of description methods. Prepare your mind to give the reader a full picture of the events that took place. Think of yourself as a reporter that is here to provide detailed descriptions of all things that happened at the specific time. By giving a full picture that may include momentary face expressions of participants or eminent gestures, the reader will be able to create a picture in his mind that is proven to fit the reality of description by 99%. To open up a secret to you, while many people agree that the information is perceived by the mind, but the actual information processing oftentimes is being conducted with the help of our subconscious mind as well. That is the reason that stands behind a good descriptive essay that is able to show all events in a format of descriptive writing to all readers in the same manner.

Waves in physics Essay Example

Waves in physics Essay Example Waves in physics Essay Waves in physics Essay Application of different type of waves in medicine Assessment type(s): MAP Criteria: A: One world, B: Communication in science Word count: 1000+ Explain the use of different waves in medicine. Your essay should: -explains how different type of waves are used to diagnose / cure different diseases. -discusses the effectiveness of science and its application in solving the problem or issue. -discusses and evaluates the implications of the use and application of science interacting with at least two of the following factors: moral, ethical, social, economic, political, cultural and environmental. You should also: -use sufficient scientific language correctly. -communicate scientific information effectively. -fully documents sources of information correctly, appropriate to the task The application of waves in medicine: Shock wave: Shock wave is one of the wave which is used in medicines. This wave was introduced 20 years ago. This application changed the treatment of Urologists. The formation of stony concretions in the bladder or urinary tract. Shock waves can treat kidney and urethral stones. Shock waves have also been used to treat fractures. The concept of orthopedic is that the shock wave reactivates healing, surrounding tissue and bones, by micro disruption which means disorder of vascular tissues to grow on local bases. It basically helps in healing and recovering tissues. Radio wave: We have learned about the understanding of radio waves by the experiments of Hertz. Radio waves are used to transfer the pattern of a patients heartbeat by a monitor to a patients home or to a nearby hospital. They are also used to convey the condition of a patient from an ambulance to a hospital so that they are ready for the tangents emergency. Radio waves are used in medicine when paramedics who is a person trained to do medical work are connected to the scene where they are to do for the upcoming patient. Electromagnetic wave: Electromagnetic waves are produced by the motion of electrically charged particles. These waves are also called electromagnetic radiation because they radiate from the electrically charged particles. They travel through empty space as well as through air and other substances. Electromagnetic waves at low frequencies are referred to as electromagnetic fields and those at very high frequencies are called electromagnetic radiations. Electromagnetic wave plays a big major role in daily life. Electromagnetic waves are used in communications, radio and television broadcasting, cellular networks and indoor wireless systems. From the results of innovations, the use of this field is very high as people prefer more of new technologies now a day. The increasing number of mobile phones users rise significant concerns due to its potential damage on people exposed by radionuclide waves. Since mobile phones are used in positions very close to the human body and require a large number of base station antennas, the public and the scientists have doubts on its damages on human body. Ultra sound: In sound waves, waves are send into bodies and are reflected back at the interface between tissues. The time taken by the waves to reflect and return tells the depth of the reflected area. The research for sound wave went across human life and had affected since the world war 2 when the research was being done during the war of sound negotiation and ranging. In sasss for gray scale images, in 1965 for real time imaging. And today used in medical imaging. Sound waves have two types of waves, specula which means reflection from large surface and scattered which means reflection from small surface. Ultra sound waves are used as medicines as it captures the internal organs and structures . Ultra sonic waves: The application of ultrasonic wave in medicine is that it used n x-rays and magnetic imaging. Among the various modern techniques for the imaging of internal organs, ultrasonic machines like x ray are very expensive including its treatment. Ultrasound is also used for treating Joint pains and for treating certain types of tumors for which the mentioned problems are heated. A very effective use of ultrasound deriving from its nature as a mechanical vibration is the elimination of kidney and bladder. One of the important advantages of ultrasound is that it is a mechanical vibration. It can also be used in places where x-ray is damaging. Ultrasound, on the other hand, gives good contrast between various types of soft tissue. All the included waves have advantages and are helpful in humans daily life. Some waves are also lawful in places where other medical machines are dangerous like ultrasonic waves instead of x-rays. Application of these waves also helps in economic development as more and more patients will do their surgery through these waves in medicine. Bibliography: Medical Physics Ultrasound. (n. D. ).

Liquid and Other Types of Lunch

Liquid and Other Types of Lunch Liquid and Other Types of Lunch Liquid and Other Types of Lunch By Maeve Maddox Until recently, I’d assumed that lunch was a clipping of luncheon. Come to find out, the words originated separately. According to the OED, luncheon is of uncertain origin, but lunch is thought to have come from Spanish lonja, â€Å"a slice.† Both luncheon and lunch first referred to a thick piece of something, such as â€Å"a hunk of bread.† In time, both words came to mean â€Å"a light repast between mealtimes.† On the Ngram Viewer, lunch and luncheon cruise along in tandem until about 1880, when lunch pulls ahead. Luncheon peaks in the 1920s and then declines. By then, some middle class speakers had come to believe that lunch was a slang word derived from luncheon and complained about its use by the younger generation. Both words still refer to a meal lighter than dinner, but now have markedly different connotations. A Google search shows 625,000,000 results for lunch compared to 43,200,000 for luncheon. The latter has acquired connotations of formality and a kind of prissiness that do not attach to lunch. One â€Å"has lunch† but â€Å"attends a luncheon.† A Web search suggests a certain gender bias: â€Å"ladies’ luncheon† brings 374,000 results compared to 34,900 for â€Å"men’s luncheon.† The word lunch has found its way into several idioms. out to lunch A person who is â€Å"out to lunch† is unaware of what is going on around him: One [presidential] candidate is simply out to lunch, unaware until recently that there was even such a thing as Common Core. to lose one’s lunch â€Å"To lose one’s lunch† is â€Å"to throw up or vomit†: Once  the sight  would have  made me lose my lunch, but it didnt anymore. Was it a bad sign that I didnt throw up on the corpses anymore? to eat your lunch To have someone â€Å"eat your lunch† is â€Å"to be soundly defeated in some competition†: If you don’t develop a marketing strategy, your competitors will eat your lunch. no such thing as a free lunch All services, gifts, and ostensibly generous gestures will have hidden costs that the recipient must pay in the end: On the Internet, as elsewhere in life, there is  no such thing as a free lunch. [Free or low-cost online services need to be paid for somehow.] liquid lunch A â€Å"liquid lunch† is a â€Å"midday meal that leads to drunkenness.† An alarming 76 per cent of employees are coming back to work drunk after taking a â€Å"liquid lunch,† according to a new survey.

Nurse Leader Interview Essay Example | Topics and Well Written Essays - 1250 words

Nurse Leader Interview - Essay Example Being honest and fair to everyone, besides sharing information with everyone and operating an open door policy, should dominate the character traits of an effective leader. The leader should go deep to ensure that they have personal contact with their employees through either face-to-face meetings or phone calls to clarify issues or seek for suggestions. In case of a problem, the leader encourages everyone to listen and learn from one another in order to build cohesion and interactivity at the workplace. A good leader does not perceive one’s position as a status but, instead, a responsibility; the leader also understands that assigned authority means that the buck stops with them. For this reason, they bear the ultimate responsibility of making the final decision. Changes in Leadership Style Because of Evolving Leadership Role From my understanding, leadership is dynamic and nursing leaders find themselves adopting new leadership styles depending on situations. Long-term exper ience in leadership and circumstances opens nurse leaders to new leadership roles that make them adopt new styles of leadership. For instance, I have made tremendous changes in my leadership style over the recent years with a notable change being adoption of facilitative and transformational leadership traits. This change has been propagated by the new demands of the medical system, which requires nurse leaders to participate in strategic decision-making and facilitate growth and development in healthcare provision. There is no doubt that our healthcare system has been facing several challenges over a long period. However, there is a sigh of relief, as the system seems to be undoing a transformation process considering the newly enacted laws in the recent past that seek to fill in the existing gaps in the system. The Congress has been steadfast to address key concerns about the ever-escalating costs and variable quality that have dogged our system for a considerably long time. The P atient Protection and Affordable Care Act is one of such incredible roles played by the Congress to address major healthcare system challenges of the 21st century (Nordal, 2011). This law in real sense cannot just be seen as a big thing in the healthcare industry – it must be valued for being transformative. This law, among other things happening in the healthcare industry, both good and bad ones, is a clear manifestation that leadership in healthcare is not just about performing a job, but all about bringing difference. This means that nurse leadership will be about not only motivating, guiding and directing teams but also facilitating change and progress. The evolving role of healthcare leaders demands that they become part of the solution to the diverse challenges the healthcare system is facing nationally and at a professional level (Nordal, 2011). In other words, leaders should be adopting facilitative and transformational leadership traits as the healthcare industry is undergoing a transformation process characterized by standardized quality and increased access for all citizens. New recruits need to be integrated into the strategic objectives of the organization to ensure that they share the same vision with the existing veterans who already understand the facility’s strategic direction. Because I understood my new roles of leading my team into the vision of the medical system, I had to start by thinking about improvements and development as it is a great requirement for a transactional

Gun Control Research Paper Example | Topics and Well Written Essays - 1000 words

Gun Control - Research Paper Example In these regards, gun control had no real impact on the murder rate in these nations. An even more startling fact is that despite gun control in many nations, the murder rate has often risen; this again demonstrates that there is no direct correlation between gun control and reduced murder rates. When considering the statistical correlation between gun control and increased or decreased crime rates, there are a number of startling facts that demonstrate gun control is an effective policy. One of the most prevalent such examples of these trends occurs when statistically comparing Canada and the United States. In both 1991 and 1995 Canada enacted increasingly stringent gun control laws, while the United States largely held onto a liberal policy regarding gun control. Rather than demonstrating a reduction in crime relative to the United States, this period witnessed an actual rise in the rate of theft and violent crime throughout Canada (‘Gun Control Fact-Sheet.’). Similar statistical trends have also been demonstrated in European countries. In 1997, the United Kingdom passed some of the most stringent anti-gun laws in the Western hemisphere. In the wake of these regulations, it was demonstrated that in large part violent crimes rates did not increase but rose by as much as forty percent (‘Gun Control Fact-Sheet.’). ... In fact, statistics demonstrate that over the last seventy-years the United States has experienced noticeably lower murder rates than the United Kingdom. While the lot of this statistical evidence is open for interpretation, a general qualitative analysis demonstrates that rather than decreasing crime, gun control laws allow criminals increased levels of freedom as they can now commit crimes unhindered by the threat of lethal self-defense. In these regards, firearms can substantially be seen to be prominent self-defense mechanisms. In developing increased gun control laws countries are in-effect reducing citizens abilities to effectively defend themselves. In addition to the statistical evidence that demonstrates a correlation between gun control and increased crime rates, general quantitative and statistical research has demonstrated that in large part gun control laws are misguided. One of the most prominent research elements related to gun control considers it in relation to self- defense. While this essay has earlier demonstrated that the use of guns for self-control can be inferred from rising crime rates in nations that implement stringent gun control laws, further research attests to the actual use of guns in these self-defense actions. In fact, guns have been implemented in self-defense over 2.5 million times annually (‘Myth #3: Gun Control Has Reduced The Crime Rates In Other Countries’ ). When one considers this from another perspective, it indicates that more than 6,000 times a day guns are used for self-defense. Within the United States itself quantitative research has examined the Brady Law in regards to crime rates. The Brady Law is

English Only Debate Paper Assignment Example | Topics and Well Written Essays - 750 words

English Only Debate Paper - Assignment Example Schools should provide the language classes our immigrants and their families need, as long as their purpose is the teaching of EnglishBut we must stop the practice of multilingual education as a means of instilling ethnic pride or as therapy for low self-esteem or out of elitist guilt over a culture built on the traditions of the West." Those who support English Only tend to be United States citizens interested in preserving our long-held common language, those who want to avoid ethnic strife, those fighting civil rights improvements for minorities, those who long for national unity and civic responsibility, those who fear assimilation will be discouraged by bilingual education and voting, those with animosity towards immigrants, those who believe Hispanics and Asians already enjoy unfair advantages, those in political leadership attempting to set a tone of isolation, racists, and those who are threatened by the concept of diversity (Crawford, 1997). According to the National Education Association (2001, pg. ... My Personal Opinion I tend to take the neutral stance on highly controversial debates because I am not one to willingly face strong confrontation. However, if I had to choose a side, I would support the English only initiatives. The reasoning that opponents to the issue give actually supports the very reason why the initiative should go through. They say it is important to preserve native culture and language, and that's one of the main reasons why they are opposed to it. Well, what about the people that were raised in the United States Do they not deserve to have their culture and language preserved as well Conclusion The purpose of this assignment has been to compare and contrast both sides of the controversial issue and explain the writer's opinion on the English Only debate. Whereas both sides make convincing arguments, it still seems only natural that a country would get to keep its native language as its own. If too many cultures and languages are supported, the United States will become something its not and may very well come apart. References Crawford, J.W. (1997). The English Only movement.
