Does chlorinated water effect plant growth?
Chlorine is considered a micro-element in plant growth and is required in small amounts for normal plant metabolism. However, applied or absorbed in high concentrations it can burn, damage or even kills plants.
Chlorine is toxic to most plants at levels exceeding 350 ppm (parts per million), some more sensitive species such as ferns show toxicity at 100 ppm or more.
The "regular" chlorinated water out of the tap doesn't have enough chlorine in it to significantly harm plants. Bottled water normally has a chlorine level of about 50 ppm.

Importance of information technology in daily life?
The computing power in the few micro processors that are now in a Ford Motor Car is much more than all the computing power that was put in the space vehicle that landed the first men on the moon and brought them back. In today's do-more-with-less business environment, with increasing demands from customers, shareholders, and regulators, the IT organization is not only asked to work harder and smarter, but is being asked to take on the role of assuring the business.
Humanity has progressed from agricultural revolution to the industrial revolution and is now moving to an information revolution. It is this awesome computing power at continuously falling prices and the computers being networked over global telecom highways that is leading to the use of Information Technology in every sector of human activity be it communication, banking, trading, learning and teaching, entertainment, socializing, government, management and librarying. Just as machines have extended man's mechanical power and his convenience and comfort, Information Technology as commonly picturized by computers, is extending man's mind or brain or intellectual power. The term information technology has ballooned to encompass many aspects of computing and technology, and the term is more recognizable than ever before.
Impacts of Technology
Technology, throughout history, has allowed people to complete more tasks in less time and with less energy. Many herald this as a way of making life easier. However, work has continued to be proportional to the amount of energy expended, rather than the quantitative amount of information or material processed. Technology has had profound effects on lifestyle throughout human history, and as the rate of progress increases, society must deal with both the good and bad implications.
In many ways, technology simplifies life:
- The rise of a leisure class
- A more informed society can make quicker responses to events and trends
- Sets the stage for more complex learning tasks
- Increases multi-tasking (although this may not be simplifying)
- Global networking
- Creates denser social circles
- Cheap price
In other ways, technology complicates life:
- Pollution is a serious problem in a technologically advanced society.
- The increase in transportation technology has brought congestion in some areas.
- Techniques
- New forms of danger existing as a consequence of new forms of technology, such as the first generation of nuclear reactors.
- New forms of entertainment, such as video games and internet access could have possible social effects on areas such as academic performance.
- Increases probability of diseases and disorders, such as obesity.
- Social separation of singular human interaction. Technology has increased the need to talk to more people faster.

What is Multi-attribute Utility Theory?
Multi-Attribute Utility Theory (MAUT) is a label for a family of methods. These methods are a means to analyze situations and create an evaluation process. The objective of MAUT is to attain a conjoint measure of the attractiveness (utility) of each outcome of a set of alternatives. Thus, the method is recommended when prospective alternatives must be evaluated to determine which alternative performs best.
The difference between active and passive monitoring sampling?
Active Sampling refers to the process of connecting sample collection media (i.e., thermal desorption tube) to a sampling train consisting of inert tubing and a sample pump operating at a know flow rate. Once activated, the sample pump draws air through the sample media, resulting in a know sample volume. Passive Sampling refers to the process of allowing sample collection media (i.e., thermal desorption tube) to passively diffuse air through the sample media without benefit of 'forced air'. This allows for longer potential sample periods without concern for overloading the sampling media. •

How are computers used in libraries?
Computers in libraries are most often used to gain access to the library's book database, a more modern version of previous library cards. This interface usually allows searching the database for a genre of books, and the ability to check whether a book is available in the building. Some libraries allow internet access from their computers for online research and other related functions.
