way to identify the brand of lipstick someone was wearing at a crime scene without removing the evidence from its bag‚ avoiding contaminating the evidence (2013). The technique by the name of Raman Spectroscopy was used (2013). This method detects laser light allowing for investigators to analyze lipstick marks left at the crime scene (2013). “Analyzing lipstick traces can be used to establish physical contact between two individuals‚ such as a victim and a suspect” (2013). This advancement is significant

different experience. The presentation held in the planetarium and the environment of this room was dark except domed ceiling and exit sign. The instructor was really informing people and kids very friendly. Instructor was describing stars with the red laser light point to understand a better view of the stars and galaxies. Kids liked that presentation because instructor was very friendly with them and he was showing stars with comparing shapes of dragon‚ dog and hunter. There was also a telescoping viewing

The second type of measurement that coincides with distance is speed. The most common devices that are used to receive speed measurements are radar guns. Georgia State University’s website‚ “Police Radar” focusses on the process of typical radar guns. Typical guns expel microwave waves off to the atmosphere while the gun is directed to hit towards a target From there‚ an object moving by who hits it sends the waves back with its modified frequency caused by the Doppler Effect (Georgia State University

Creative writing! The End Before My Eyes! ‘Another typical day‚’ I said to myself when I woke up this morning; but I could never have been so wrong in my entire life! It was a Tuesday morning and the moon was still out. I didn’t think anything of it at the time. I bathed and got ready to get out my house since my bus was due in 10mins. As soon as I got out the moon became the colour of pure red blood. It intrigued me. So I got on the yellow knocked up bus and got out my little ‘Blue Note’

Light that is visible to the human eye is a small portion of the electromagnetic spectrum which can vary in colour based on the wavelength of what is being seen at any particular time. This visible light has a primary function of causing electrons to become more active with higher energy rates. The colour that is seen revolves around the size of this portion which is noted as the wavelength. White light is a culmination of all colours which is the cause of it being the brightest. Furthermore‚ when

In the Polaroid design the membrane is a special foil consisting of a Kempton® film coated with gold. The foil is stretched over a V-grooved plate‚ Figure 2.5. The transducer is protected by stainless steel housing. A few models with different housings are available. The sizes of these transducers are the main drawback since they are from 30 up to 45 mm in diameter. A further analysis of this structure and its dynamic features is found in [Attila et. al.‚ 1995]. The piezoelectric transducer is based

RESEARCH: SENSORS ULTRASONIC RANGE FINDER An ultrasonic range finder sensor enables a robot to detect obstacles in its path by utilizing the propagation of high-frequency sound waves. The sensor emits a 40 kHz sound wave‚ which bounces off a reflective surface and returns to the sensor. Then‚ using the amount of time it takes for the wave to return to the sensor‚ the distance to the object can be computed. Unlike the bumper switch and limit switch that alert you when they have been hit‚ the ultrasonic

Where the Incision is Located Inframammary incisions are the incisions that are made in the breast’s bottom crease‚ where the chest wall meets the lower protrusion of the breast. You will probably be instructed to wait at least 2 to 4 weeks before getting back to doing upper body exercises if this is the location of your implant. In the meantime‚ you should not lift your hands over your head during recovery. When you minimize the stain on this part of your body‚ it will result in healthier healing
