Making a Laser Beam Security Alarm Circuit Posted by Swagatam Majumdar We have often seen laser alarm system as an integral part of security solution especially for a location which deserves hi-level security. Right from a museum preserving priceless historical possession; to a safety bank vault; and even in thriller flicks where the protagonist is seen on and often tied in the ray of red light beams‚ while trying to reach a safe vault; one is well acquainted with the usage of laser light beams

Abstract Earth is the only planet we can live in and it’s the only planet we have so we have to take care of it. Knowing this we are still hurting it‚ whether it is through degrading the soil or through CFC’s. Global Warming is real and its hurting our environment and it’s entirely our fault. It’s true that Global Warming happens naturally however because of the human race we have increased how fast it’s happening. There have been many meetings with other nations to control the amount of carbon-dioxide

black and silver will be explored. Infrared radiation is invisible radiant energy‚ it lies between the visible light and the microwave portion of the electromagnetic spectrum. Heat is the main source of infrared energy‚ heat is produced by the movement of atoms and molecules. This experiment was conducted to investigate how black‚ white‚ and silver cans would absorb heat. The electromagnetic spectrum is made up of gamma rays‚ X-rays‚ ultraviolet‚ visible‚ infrared‚ microwaves and radio waves. What

Abstract In this experiment‚ the nature of linkage isomers will be observed on the example of nitritopentaamminecobalt(III) Chloride and nitropentaamminecobalt(III) Chloride. Their relative stability will be compared on standard conditions and the infrared spectroscopy of both the isomers will be obtained to analyze the characteristic absorption bands for the nitro and nitrito group. Yield for nitritopentamminecobalt(III) Chloride was obtained to be = 1.9221 g(73.24 %) and yield for nitropentamminecobalt(III)

Comparing these values with the literature melting point of 262 - 264°C shows that the product was indeed 9‚ 10-dihydroanthracene-9‚ 10-α‚ β-succinic anhydride and that recrystallization yielded a purer product. Upon examination of an infrared spectrum of the product and comparison with anthracene and maleic anhydride spectra‚ it was found that the product spectrum had similarities with both the anthracene spectrum and the maleic anhydride spectrum. This indicated that the product was

Home is Where the Heart is In Ghost Hunter’s recent episode Home is Where the Heart is‚ the ghost hunter team heads to Beardslee Castle in Little Falls‚ NY. Some interesting facts about this castle is that the owner had hanged himself in the house. Along with the hanging other individuals have died in the house. The team investigates to see if they can debunk any of the reported occurrences. The Ghost Hunter team wires the castle/restaurant with video surveillance equipment. By doing this
