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

INTRODUCTION In a country like india agriculture is a majour source of income still today a majourity of the population is living in the rural areas and depending on the agriculture for their earnings. This pattern has been followed for many years and people work on their basic instrument depending fully on the mercy of weather. And today to ADD TO THEIR VOWS THE EM WAYS BEING EMMITED FROM THE CELL TOWERS ERRECTED FOR MORDANIZATION IS MAKING THEIR EFFERTS useless. The impact is not visible

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

------------------------------------------------- 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

ii) Remote control For ensuring the safety of the user this system provides an additional type of controlling other than BRI and it is Remote control‚ which means robot is controlled by an external person. The switching of the control system is optional which is done by a mode selector. Simplified block diagram of remote control is shown in Fig.5. Atmel microcontroller is used in the design process of remote control. These types of microcontroller provide justified technology‚ an affluent efficiency

Emission Spectroscopy The purpose of this lab was to see that when elements are heated‚ they may enter and excited state. We proved this by doing a flame test. During Part A‚ we used a spectroscope where all of the colors are arranged for you; whereas in Part B‚ we could see and make the colors ourselves and get a more accurate reading of the flames. We had specific elements we were told to put on the wire loop‚ and when we did that we saw different color flames come out of the Bunsen burner. That

UV. Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. It is more specific than the general term electromagnetic spectroscopy in that spectrophotometry deals with visible light‚ near-ultraviolet‚ and near-infrared‚ but does not cover time-resolved spectroscopic techniques. Spectrophotometry involves the use of a spectrophotometer. A spectrophotometer is a photometer that can measure intensity as a function of the
