The Malthusian Theory The Malthusian Theory of Population states that the growth of population is exponential as it doubles every twenty-five years, while that of food is linear (Ross (1998). Although an increase in population in a given area decreases the distribution of resources to the people, the Malthusian Theory fails to consider significant factors of population growth. Therefore, this essay describes the reasons why I am against Malthus’ theory. One, the theory’s mathematical proposition is not supported by relevant facts in the real world (De Marchi & Sturges, 1973). According to Malthus, the growth is population is geometrical, while the food supply is by arithmetic. However, there has been no evidence in any country that this theory works, where the population and food supply grew by geometrical and arithmetic methods, respectively. For example, there should have been facts that a particular country’s population doubled in 25 years. Besides, the Malthusian Theory ignores external factors such as economic development that affect the population’s demographics. In a case where the population grows economically, there is an expected decrease in the…
What are the things to consider about hydraulic and mechanical dredging? You have decided that your pond needs some dredging, and you have the names of a couple of companies in your area for the job. But, that is not where your responsibility ends. You need to decide between mechanical and hydraulic dredging. It is important to know a couple of facts about both these types to know which one is right for your pond. You will have to consider a couple of things when you are trying to choose between hydraulic and mechanical dredging. Some of those things are described below in detail. Read on to know more about hydraulic and mechanical dredging. Tools: Mechanical dredging is all about using heavy equipment like excavators by keeping it on the edge of the water or on barges. It helps in digging out the bed of the waterbody and removing the sediment. This sediment gets hauled away than for reuse or disposal. As opposed to that, hydraulic dredging is all about using suction for removing the sediment. It gets transported using…
Tuberculosis essay Introduction Tuberculosis is one of the infectious illnesses caused by mycobacterium tuberculosis. Naturally, it affects the lungs but can affect other body parts. This disease is not common in high-income nations but rampant in low- and middle-income countries; it is still a real public health issue. It was reported that ten to twelve million new cases occurred every year between the years 2001 and 2011. (Nemeth & Gold, 2019) Each year about two million people perished from the illness. In older people, Tuberculosis is the second leading cause of death in low-income nations after HIV. The disease is a significant issue in developing countries to children, where it kills more than 200,000 children annually. Treatment for tuberculosis illness remains a problem for patients and a massive load on the health care system. Medicine-susceptible Tuberculosis needs close observation for a minimum of at least eight months of therapy. A multidrug-resistant tuberculosis analysis will need almost two years of management with poorly accepted and less effective medication. On many occasions, the investigation is still primarily established on direct microscopy,…
Categories of Controlled Airspace Controlled airspace refers to the generic term used to cover varying classifications of airspace, which consists of Class A, Class B, Class C, Class D, and Class E. Class A Airspace in Class A is that which ranges from 18000 feet MSL (mean sea level), including 600 flight level (FL). This airspace also includes that which is overlying water of the coast within 12 NM (nautical miles) within Alaska and 48 neighboring states. As explained by FAA, all operations in this airspace are often conducted under the requirements of instrument flight rules (IFR), which should be done only after the issuance of an air traffic control (ATC) clearance before entering into space (Federal Aviation Administration, 2009). This airspace must also be well equipped with a functioning two-way radio with the capability of communicating with the frequency that has been assigned by ATC. Class B Airspace in this class is from the ground to 10,000 feet MSL in the nation’s busiest airports in terms of passenger enplanements and airport IFR operations. The configuration of the airspace in…

SLHS Annotated Bibliography Annotated Bibliography Mark Stibich, Ph.D. – Reviewed by a Board-certified Physician. “What Is the Life Expectancy of a Person With ALS?” Verywell. N.p., n.d. Web. 08 April. 2017. The above article begins by briefly explaining and defining ALS. The article explains that ALS is a neurodegenerative type of disease that significantly affects all nerve cells in the spinal cord and brain. The statistics obtained showed that 50% of the affected generation lived more than three years, 20% lived more than five years, a 10% affected population lived more than ten years, and the last 5% lived more than 20 years. The source further explains and gives precise details on ways of increasing life expectancy. Some of the discussed ways include noninvasive ventilation, percutaneous endoscopic gastronomy, and medications. However, the only drug that is approved by the FDA is called Riluzole, which assists in prolonging life expectancies for a few months. There exist other medications that improve life’s quality. Noninvasive ventilation assists in increasing life expectancy to about 7-12 months and uses a mask and tube, which…
Digital Pianos A digital piano is a designed electronic keyboard type that primarily serves the purpose of producing an enjoyable sound. Digital pianos synthesize recorded samples or emulation of acoustic pianos whereby they get amplified through internal loudspeakers. Moreover, digital pianos incorporate keys that are weighted which effectively recreate an excellent feel. Some digital pianos are designed to resemble a grand or upright piano. Digital pianos are small, weigh less, and they cost less (Riola, Michael, et al., 27). The keyboard comes with 88 keys and does not need tuning, but their overall tuning can get tuned to match the tuning of another instrument effectively. This paper is going to discuss various features associated with digital pianos. Important advantages include; Portability/convenience- digital pianos are lighter and more compact. Cost- these pianos are slightly cheaper and cost far much less than acoustic pianos. Versatility/volume- The volume of digital pianos is easy to control, and one can control over wide ranges, and silent practices are made possible by using headphones. Connectivity- Majority of digital computers possess MIDI-based capability to allow an…

The Environmental Performance Of Canadian Oil Sands Introduction Oil sands refer to loose sand deposits containing highly viscous petroleum known as bitumen. Oil sands are constituted of a mixture of sand, clay, water and bitumen oil, which are situated in the Northeastern Alberta in Canada, which include Athabasca, Cold Lake and Peace River. The oil sand deposits in Canada are the largest in the world, contributing to over 10% of the world’s oil reserves. (Berkowitz &Speight,1975). Conventional crude oil, on the other hand, refers to a liquid petroleum that is pumped from underground. It varies widely in terms of sulfur content, viscosity and density. It is either classified as light, medium or heavy, which is the oils relative density based on API gravity. While crude oil can be pumped from the deposits underground as it flows, oil sand is too thick and doesn’t flow; hence it cannot be pumped from the ground(Berkowitz &Speight,1975). Instead, it is mined through the injection of Steam into the well, which heats it first. Several methods are used in the extraction of oil sands. Examples…
