The Radio is one of the most important means of communication that has affected nearly every single person on the planet. The radio can transmit messages from all over the world in an instant so that a person can listen to what is on it. The history of this device began in the 1800's and continued being developed and improved on as time went by, which was created by different inventors and became the radio as people know it today. Heinrich Hertz discovered radio waves in 1887. The waves moved…

What is a RIN A Renewable Identification Number (RIN) is a serial number assigned to biofuel batches used to track its production, use, and trading activity. RINs are required by the United States Environmental Protection Agency under the Renewable Fuel Standard (RFS) program. RINs are credits used for compliance, and are the currency of the RFS program. The RFS program is an initiative created by Congress to reduce the emissions of greenhouse gases in efforts to expand the nations renewable…

When looking at a flashlight, it can be determined that the flashlight itself resembles a parabola. Flashlights are supposed to be able to focus on a single point, which is infinitely small. Since a flashlight is supposed to mirror a parabola, the flashlight has similar components as a parabola. The filament, which is the part of the flashlight that gives light, resembles the focus on a parabola. The filament is a three dimensional object so it is infinitely larger than a point, yet the filament…

Lesson Plan Teach 1 Name: Spectra and Stars Standard: Identify and compare characteristics of the electromagnetic spectrum such as wavelength, frequency, use, and hazards and recognize its application to an understanding of planter images and satellite photographs. Objective: The students will be able to – 1. Recognize that white light is made up of a spectrum of many different colors. 2. Explain how different colors of light can be absorbed by colored filters. Engage 1. Remembering- How…

Conventional methods of teaching are loathed for their intention of manipulation & control. Having seen through something of ourselves that we do not seem to trust, Education itself is a process, where the subjects’ (students) potential is being stimulated; curiosity gets directed towards their self-actualizations. This can be achieved via a single approach that conducts teacher-centered teaching, alternatively doable via multiple approaches such as self-supervised learning, which seems…

3.4. Friction Characteristics of the NCD, MCD and boron doped NCD Coatings against Alumina Balls The friction coefficient curves of NCD, MCD and boron-doped diamond films sliding with Al2O3 balls are shown in figure 4, figure 5 and figure 6, respectively, for a sliding speed of 8 m/s and a load of 1N, 5N and 10N, respectively. Figure 4 (a), figure 5 (a) and figure 6 (a) show the friction coefficient of NCD, MCD and BDNCD at 1 N, respectively. Figure 4 (b), figure 5 (b) and figure 6 (b) show…

What is refraction Refraction is the bending of light when it passes from one medium to another, as light travels through one medium such as air it will travel at a certain velocity but once it enters another medium such as glass it will change direction due to the increase in density of the medium which slows down the velocity of the light. The amount that the light bends as it travels through a medium depends on how drastic the difference in optical density is. For example if light were to…

Figure 21: Dependence of the penetration depth on dwell times for different indentation peak loads Figure 22: Dependence of the penetration depth on dwell time for different indentation peak loads in ln-ln plot 5.4 HV vs. penetration depth Figure 23 shows the dependence of the Vickers hardness on the indenter penetration depth for 100mN to 1000mN and 10 s to 60 s dwelling time. The highest hardness value is 15.6GPa. As the indenter penetration depth increases, the hardness value decreases.…

electrons are subjected to a voltage, resulting in a voltage difference between the cathode and the ground in a manner that minimizes electronic collisions. The cathode ray is controlled by the electromagnetic lenses, generated by the coils that circulates around the tube. The effect of the electromagnetic lenses can be adjusted by changing the electricity flowing in the coils. The cathode ray is focused into a narrow beam and shot directly to the specimen. Formation of an image of…

An inverted fluorescence microscope is an inverted compound light microscope equipped with modules to internally separate the different wavelengths of light, and direct them to respective detection channels. Its main components include a light source, an objective, a filter cube and a detection unit, which can be an eyepiece or a camera (Fig.1). Filter cube is a component which separates a fluorescence microscope from a light microscope. It consists of one excitation filter, one emission filter…
