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

at different pHs Abstract These experiments aimed to determine the optimum pH ranges various buffers are effective and provide opportunity for the use of the Henderson-Hasselbalch equation to prepare a buffer of a specific pH. Three different buffer systems were initially investigated; volumes of weak acid and weak bases of specified concentration were prepared and titrated against strong acid or strong base solutions with pH readings taken at frequent intervals to determine pH ranges over which

manuscript. (Page 8‚ line 13-15) Comment 14: Page 8: Explain if pH was controlled during fermentation. In any case‚ do a reference in the result section to the pH at the end of fermentation Response: The pH was not directly controlled during the fermentation. In the line with typical studies conducted for ABE production‚ the medium was supplemented with buffer (50 g/L KH2PO4‚ 50 g/L K2HPO4‚ 220 g/L C2H3O2NH4) as an approach to control the pH changes during the fermentation. In addition‚ it has been reported

Comparison of Java‚ JavaScript‚ Java Applets and Java Beans Team C WEB 420 Introduction Starting back in the early 1990 ’s with the introduction of Java to the computer scene there has been many updates and advances in how languages interact with web based programs. In this paper we are going to highlight several areas of several different Java flavors. The flavors we are addressing are Java‚ JavaScript‚ Java Applets and JavaBeans. We will discuss their history‚ features‚ usage and syntax and

aerobic cellular respiration or other substances needed for growth. After the leaves of the seed are exposed to light‚ photosynthesis provides the seed with food and the food stores are no longer needed. In this research‚ the relationship between Mung bean light exposure and germination will be investigated. In order for germination to take place certain external factors are needed. Water must be available for the seed to hydrate the dry tissues to activate the seed’s metabolism. Oxygen must also

BEAN BAG ISOTOPES:ABUNDANCE AND ATOMIC MASS LAB Prelab A new atomic theory‚ in which all atoms of the same element are identical to one another and equal in mass‚ was proposed by the scientist Dalton. Although the theory had its flaws and was simple‚ it was revolutionary. Scientists became able to study the actual structure and mass of atoms after the discovery of radioactivity. Soon‚ isotopes were discovered‚ as atoms of the same element which have been built up to have different masses. Purpose

EXECUTIVE SUMMARY Indonesia is the third largest producer of cocoa in the world after Ghana and the Ivory Coast‚ and the most significant cocoa bean supplier in East Asia. Indonesia’s biggest competitive advantages include its low cost‚ high production capacity (availability of supply)‚ efficient infrastructure and open trading/marketing system (business environment). Although the cocoa value chain in Indonesia has experienced phenomenal growth over the past few decades‚ its continued competitiveness
