QUALITIES OF GOOD WATER by Dr. Robert O. Young There are many measurements of water‚ but the most important for determining the best water to drink are‚ the pH‚ oxidative reduction potential—or energy potential/activity—molecular structure‚ and purity. Science has helped us to determine that the best measurements for our drinking water are the pH and purity‚ but little understood is the importance of the molecular structure of water. Assuming that most waters that humans are drinking are purified

Effects of pH on fungal amylase activity BI 211 November 25‚ 2011 Introduction In recent years‚ the uses of microorganisms have become a huge importance to industry and sparked a large interest into the exploration of enzyme activity in microorganisms. Amylase is one of the most widely used enzyme required for the preparation of fermented foods. Apart from food and starch industries‚ in which demand for them is increasing continuously‚ amylase is also used in

activity of the enzyme catecholase in different pH levels as well as its absorbance in differently concentrated solutions. A spetrophotometer was used to measure the absorbance of the enzyme catecholase in different pH solutions as well as to measure the absorbance of catecholase in solutions with different concentrations of potato juice and phosphate buffers. Absorbance of the enzyme catecholase was at an optimum level when pH was close to neutral. When pH was acidic or basic‚ the catecholase was less

Enzyme Activators and Inhibitors Lucia House AP Biology‚ Block 4 Mr. Trice October 18‚ 2012 Introduction: Metabolism is the totality of all of an organism’s chemical reactions. Chemical reactions occur due to enzymes‚ a substance which acts as a catalyst in driving chemical reactions in order to produce a desired product (Campbell and Reece‚ 2002). A catalyst is usually a protein; however‚ some catalytic molecules counter this generalization. A discovery made in the early nineteen- nineties

Q1-1) Identify the five components of a data communications system. 1.Message. 2.Sender 3.Receiver. 4.Transmission medium. 5.Protocol. Q1-11) Why are protocols needed? To achieve end-to-end delivery of data. Q-17) Explain the difference between an Internet draft and a proposed standard? - An Internet draft is a working document (a work inprogress) with no official status and a six- month lifetime. - A proposed standard is elevated to draft standard

Background An indicator is a halochromic chemical compound that is added to a solution to determine its pH. It is a chemical detector for hydronium ions. The indicator changes colour to show the pH of the solution. Some indicates are not very precise and only tell us whether the solution is acidic or basic. When the indicator is added to the solution‚ they bind to hydrogen or hydroxide ions. The different electron configurations of the bound indicator cause the indicator ’s colour to change.

1) Distinguish between the FTP and TELNET protocols. File Transfer Protocol (FTP) is used to transfer text files‚ programs‚ spreadsheets‚ and databases across the Internet. TELNET is a terminal emulation protocol used on TCP/IP-based networks. It allows users to run programs and review data from a remote terminal or computer. TELNET is an inherent part of the TCP/IP communications protocol. While both protocols deal with data transfer‚ FTP is useful for perusing a file of data as if the user were

Dynamic Host Configuration Protocol (DHCP) "The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP)." [1] When a computer uses a static IP address‚ it means that the computer is manually configured to use a specific IP address. One problem with static assignment‚ which can result from user error or inattention to detail‚ occurs when two

INTELLECT SPEED BREAKER USING CAN PROTOCOL This project deals with limiting the speed of the vehicle by employing technology of embedded systems using “Peripheral Interface Controller (PIC 16F877A)”‚ when the vehicle enters the speed limiting zone. The parameter to be controlled in this project is speed. PIC has the advantage of enhanced FLASH memory with the modified Harvard architecture and having simple 35 instructions. A Controller Area Network (CAN) protocol is ideally suited to automobiles

September 10th‚ 2013 EXPERIMENT 1 LEARNING BASIC OPERATIONS: THE EFFECT OF PH ON A FOOD PRESERVATIVE Purpose: The purpose of this experiment was to investigate a competitor’s claim that the food preservative‚ sodium benzoate (C6H5COONa)‚ made by Fresh Foods International (FFI)‚ changed into a new substance in stomach acid. Stomach acid has a pH between 1 and 3 due to the hydrochloric acid content. Based on the net equation given in the book as well as the solubility of the product our hypothesis
