Effec | Effect of caffeine on plant growth | Description This science fair project was performed to find out the effect on plant growth of adding caffeine to the soil. The experiment was done by using mung bean plants and watering them daily with water‚ water mixed with caffeine and with a coffee mixture. Hypothesis The mung beans watered using the coffee mixture will grow the fastest. Overview Caffeine and plant growth The effect of adding caffeine to the soil and its effect on plant

Rapid Prototyping can be defined as a group of techniques used to quickly fabricate a scale model of a part or assembly using three-dimensional computer aided design (CAD) data. What is commonly considered to be the first RP technique‚ Stereolithography‚ was developed by 3D Systems of Valencia. Rapid Prototyping has also been referred to as solid free-form manufacturing‚ computer automated manufacturing‚ and layered manufacturing. RP models can be used for testing‚ such as when an airfoil shape

Paper: Technology’s Effect on Society Many people today love the amount of advanced technology available that continues to evolve at a faster and faster rate with each passing day. Things that did not seem possible a few years ago are a reality today‚ which shows us that even our wildest dreams could become reality. We have access to cell phones that are more like computers‚ the internet and all of its outlets‚ electronic books… if you can think of something technological that would make life

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is

ABSTRACT Rapid prototyping is a revolutionary and powerful technology with wide range of applications. The process of prototyping involves quick building up of a prototype or working model for the purpose of testing the various design features‚ ideas‚ concepts‚ functionality‚ output and performance. The user is able to give immediate feedback regarding the prototype and its performance. Rapid prototyping is essential part of the process of system designing and it is believed to be quite beneficial

Preston Tucker Professor Kenney EN101 - 29 Cause and Effect The Effects of Computers on Society Starting in the mid 1930’s‚ our day to day lives revolve around and depend on one crucial piece of equipment‚ the computer. If these computers did not exist‚ we wouldn’t be able to drive the cars we drive today. Calculators wouldn’t exist; making high level Mathematics exponentially more difficult. Our cell phones wouldn’t send or receive signals rendering them as useful as two paper cups with a

The Effects of Antibiotics on Bacterial Growth Biology II 1996 Bacteria are the most common and ancient microorganisms on earth. Most bacteria are microscopic‚ measuring 1 micron in length. However‚ colonies of bacteria grown in a laboratory petri dish can be seen with the unaided eye. There are many divisions and classifications of bacteria that assist in identifying them. The first two types of bacteria are archaebacteria and eubacteria. Both groups have common ancestors dating to more
