the average temperature of the Earth in recent years and its projected continuation. 2. CAUSES OF GLOBAL WARMING: a) The Greenhouse Effect- The term “Greenhouse Effect” refers to the process by which absorption and emission of infrared radiation atmosphere gases (mainly Greenhouse gases such as CO‚ NO‚ and Carbon Monoxide) warms the Earth’s atmosphere and surface. b) Solar Variations- Solar variations are changes in the amount of radiant energy emitted by the Sun. It is

What is the impact of human activity on the natural environment? Answer: Humans are a part of the natural environment. Unfortunately‚ we have not yet learnt to moderate our activities in such a way as to help the environment. Human activities often lead to degradation of the environment. Impacts of humans include: • pollution - land‚ freshwater creeks and rivers‚ seas and oceans‚ and air • deforestation and destruction of habitats • endangerment and extinction of flora and fauna species

today’s technology world. The four kinds of cordless technologies I would prefer to speak about will be IR or Infrared‚ satellite signals‚ microwave signals‚ as well as radio systems. These kinds of systems transmit data in various ways and strengths. All of these types of systems have their advantages and disadvantages. Infrared is dependent on the utilization of infrared light signals. Infrared light isn’t noticeable by the human eye. This kind of signal utilized LEDs and ILDs to transmit signals as

This mild preoccupation has now turned into a complete obsession with constantly having a screen to stare at for hours.

------------------------------------------------- Etymology The word horticulture is modeled after agriculture‚ and comes from the Latin hortus "garden" and cultūra "cultivation"‚ from cultus‚ the perfect passive participle of the verb colō "I cultivate".Hortus is cognate with the native English word yard (in the meaning of land associated with a building) and also the borrowed word garden. ------------------------------------------------- Understanding horticulture Horticulture is a term

Competition There are only a few key players currently in this market that focus on the building trades industry. They are FLIR Systems‚ LumaSense‚ Jenoptik‚ and InfraRed Solutions. The cameras range in price from $7‚000 - $40‚000. FLIR Systems is seen as the biggest competition. FLIR‚ established in 1978‚ is headquartered in Wilsonville‚ Oregon. They have worldwide facilities for manufacturing‚ sales and service‚ and research and development. FLIR not only manufactures thermal cameras‚ but they

increased levels of carbon dioxide‚ CFCs‚ and other pollutants. The greenhouse effect is the trapping of the sun ’s warmth in a planet ’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet ’s surface. In simpler terms‚ this means that the pollution emitted from the earth‚ such as the gasses from factories‚ cars etc. enter the atmosphere and the co2 from these gases absorb the heat from the sun and

energy. Light’s lower frequency is red‚ and the higher frequency is blue. Like sound‚ light has frequencies humans can’t detect. Ultraviolet light is at a frequency higher than violet‚ and infrared is at the frequency lower than the red of visible light. We get UV (ultraviolet) rays from the sun‚ and infrared is used in night vision to see better. Sound travels at about 1‚200 k/hr while light travels at about 300‚000 km/s. It’s easy to notice how slowly sound travels. Take‚ for instance‚ a soccer

the IR beam gets interrupted when someone is standing at the gate or passing through it. The transmitter circuit (see Fig. 1) is built around timer NE555 (IC1)‚ which is wired as an astable multivibrator producing a frequency of about 38 kHz. The infrared (IR) beam is transmitted through IR LED1. The receiver circuit is shown in Fig. 2. It comprises IR sensor TSOP1738 (IR RX1)‚ npn transistor BC548 (T1)‚ timer NE555 (IC2) and some resistors and capacitors. IC2 is wired as a monostable multivibrator
