ABSTRACT
A partial differential equation is a differential equation that contain unknown multivariable functions and their partial derivatives while ordinary differential equations contains function of a single variables and their derivatives. Therefore, an ordinary differential equation is a special case of partial differential equation but the behaviour of a solution is quite different. It is much more complicated in the case of partial differential equation because it has more than one independent variable. Partial differential equation can be used to describe the various topics in physics such as propagation of sound and wave, heat, electrostatics, Maxwell equation in electromagnetism, elasticity, quantum mechanics, Hamilton-Jacobi theory.

The independent variables will be denoted by x and y and the dependent variables denoted by z. The partial differentials coefficients are denoted as follows:
∂z/∂x=p ∂z/∂y=q (∂^2 z)/〖∂x〗^2 =r (∂^2 z)/∂x∂y=s (∂^2 z)/〖∂y〗^2

IN HEAT FLOW[8]
Heat is the transfer of energy between two bodies. One dimensional heat equation
When the heat flow along the straight lines, then the flow is called one-dimensional.
Let us consider the heat flow in a bar or rod along the x-axis. Consider a rod of homogeneous material of density is ρ (gm⁄〖cm〗^3 ) and having a constant cross-sectional area A (〖cm〗^2 ). Let c be the specific heat and k be thermal conductivity of material. We suppose that the sides of the bar are insulated and the loss of heat from the sides by conduction or radiations is negligible. Take an end of the bar as the origin and the direction of heat flow as the positive x-axis.
The data which was collected in Procedure A was able to produce a relatively straight line. Even though this did have few straying points, there was a positive correlation. This lab was able to support Newton’s Law of Heating and Cooling.
In this equation, Y is the dependent variable, and X is the independent variable. α is the intercept of the regression line, and β is the slope of the regression line. e is the random disturbance term.
Did you know tobacco and alcohol use cause over 475,000 deaths in the U.S. annually? To assist young people in avoiding these harmful behaviors, the D.A.R.E. program enhances the knowledge and awareness of the hazards regarding dangerous substances throughout a ten week program. The acronym D.A.R.E. stands for drugs, abuse, resistance, and education. D.A.R.E. ensures the safety of adolescents in various situations and instills beneficial strategies, techniques, and tips to aid young people in making responsible decisions.

Prior to the winding-up of an insolvent company, its creditors may individually enforce any measure available to them in order to obtain payment of the debt owed to them by such company. However, upon the opening of the winding-up proceedings these individual actions are replaced by a collective insolvency regime which attempts to ensure the rateable and equitable distribution of the assets of the insolvent company among its creditors. This distribution is known as pari passu distribution.
Diffusion and osmosis refer to passive transport systems where molecules and ions move down concentration gradients driven by thermal motion. The concentration gradients are setup in solutions in living systems that are separated by biological membranes. Diffusion refers to the spontaneous movement of particles, molecules, or ions from an area of higher concentration to an area of lower concentration. The process occurs slowly without any expenditure of energy. Diffusion occurs in liquids and gases. An example of diffusion is the movement of the smell of a spray from the point of spraying to the rest of the room. On the other hand, osmosis refers to the movement of molecules of a solvent such as water from an area of low concentration to an area of higher concentration. It is a special type of diffusion that occurs in reverse. An example of osmosis is the process through which animal cells feed on the food they partake. Thus, diffusion and osmosis are called passive transport systems because they enable cells of living systems to move molecules in
The dynamic systems view was developed by Arnold Gesell in 1934 and explores how humans develop their motor skills. From Mr. Gesell’s observations, he was able to conclude that children develop their motor skills in a specific order and time frame. He concluded that children roll, walk, sit, and stand as a result of several factors – the ability to move, the environmental support to move and the motivation/goal to move. Once the child has the motivation, ability, and support, they accept the new challenge. After several failed and successful attempts, they begin to fine-tune and master the movement with continued support and motivation. The dynamic systems theory is not a random process that children experience, the skills are calculated and develop over a period of time.

Shelley's "Ode to the West Wind" appears more complex at first than it really is because the poem is structured much like a long, complex sentence in which the main clause does not appear until the last of five fourteen line sections. The poem's main idea is held in suspension for 56 lines before the reader sees exactly what Shelley is saying to the west wind, and why he's saying it. In the first four sections Shelley addresses the west wind in three different ways, each one evoking the wind's power and beauty. And each section ends with Shelley asking the West Wind to "hear, oh hear!" The reader's curiosity is therefore both aroused and suspended, because we know the west wind is supposed to "hear" something, but we aren't told what the wind is suposed to hear or is supposed to do.
According to NASA, climate models are “aimed at the development of coupled atmosphere-ocean models for simulating Earth 's climate system.” In greater depth, the Universite Catholique de Louvan provides the following definition:
There have been many great mathematicians in the world, though many are not well known. People have been studying math for ages, the oldest mathematical object dated all the way back to around 35,000 BC. There are still mathematicians today, studying math and figuring out ways to improve the mathematical world. Some of the most well-known mathematicians include Isaac Newton, Albert Einstein, and Aristotle. These mathematicians (and many more) have influenced the mathematical world and mathematics would not be where it is today without them. There were many great individuals who contributed greatly in mathematics but there was one family with eight great mathematicians who were very influential in mathematics. This was the Bernoulli family. The Bernoulli family contributed a lot to mathematics, medicine, physics, and other areas. Even though they were great mathematicians, there was also hatred and jealousy between many of them. These men did not want their brothers or sons outdoing them in mathematics. Most Bernoulli fathers told their sons not to study mathematics even if they wanted. They were told to study medicine, business, or law, instead, though most of them found a way to study mathematics. The mathematicians in this family include Jacob, Johann, Daniel, Nicolaus I, Nicolaus II, Johann II, Johann III, and Jacob II Bernoulli.
Being a new college student can be tough. Balancing new work levels, trying to manage your time & also getting enough sleep are the main difficulties for a new college student coming straight from high school in my opinion. These problems can be easily solved by going to class and using the resources that are provided to you. This may not seem difficult but in reality it 's right in front of your face.
The concept of potential problem analysis, which is also known as potential opportunity analysis, is one of the stages in the Kepner-Tregoe approach for the problem-solving process. This concept was introduced to help in analyzing the consequences of a decision in order to identify what could potentially go wrong and to create initiatives that could address the problems or issues once they actually emerge. Generally, the potential problem analysis technique is developed to offer a comprehensive evaluation of a created idea or action so as to predict any probability for something going wrong. Therefore, this concept or procedure helps an individual to expected problems before they take place and to develop necessary measures that could be implemented to prevent the probable problem from taking place or lessen its effect.
There are lots of environmental issues going on globally. The earth faces problems such as pollution, global warming, waste disposal, and loss of biodiversity. These are just a small amount of issues out of the so many. These environmental problems pose an abundant amount of risk to the health of humans and animals. There needs to be a solution to all these problems and that is by informing others, so that way everyone can make the environment a better place.
