.... The major components of ARD formation are reactive sulfide minerals, oxygen, and water. Biological activity and reactions is what is responsible for the production of ARD. These reactions make low pH water that has the ability to mobilize heavy metals contained in geological materials with which it comes in contact. "ARD causes a devastating impact on the quality of the ground or surface water it discharges to. (Ellison & Hutchison)" ACID MINE DRAINAGE Within the mining process there are several sources that cause ARD. No matter what activities occur, ARD usually occurs when certain conditions are met. These conditions are the factors that limit or accelerate the ....

.... Layer 2 (media access control/logical link control) of the Open System Interconnect (OSI) Reference Model. Thus, Layer 3 (network) protocols, such as IP traffic, can be seamlessly delivered over the cable modem platform to end-users. . Since cable modem technology is very recent the conflict exists between different standards. The only specification that has been approved by ITU (in 1998) is DOCSIS (Data Over Cable Service Interface Specifications) which was developed by MCNS, CabeLabs, Arthur D. Little and consortium of North American MCOs. Later that year CableLabs established certification program that would ensure interoperability among the equipment from different ....

.... how to regulate it. This paper will look into those questions and what actually makes up this new virtual world that we are creating for ourselves called cyberspace. In the 1950’s and 60’s the fear of nuclear attack was constantly on the minds of the American people and the government. The government therefore developed a corporation called RAND that they put in charge of making a network that could be protected from nuclear attack and could guarantee that we could still fire our own nuclear missiles in our defense. Soon major schools and corporations threw their hats into the race for a network in which information could be sent electronically. Throughout ....

.... is made possible due to the basic properties of the NH2 group and the acidic properties of the COOH group. The amine group (NH2) is Lewis base because it has a lone electron pair which makes it susceptible to a coordinate covalent bond with a hydrogen ion. Also, the carboxylic group is a Lewis acidic because it is able to donate a hydrogen ion (Kotz et al., 1996). Other forms of amino acids also exist. Amino acids may exists as acidic or basic salts. For example, if the glycine reacted with HCl, the resulting amino acid would be glycine hydrochloride (see fig. 2). Glycine hydrochloride is an example of an acidic salt form of the amino acid. Likewise, if NaOH ....

.... from being strangled, which allowed for faster plowing and greater food production. Around the same time as the chest harness’ invention, medieval villagers were organizing their land into a two field system of agriculture. This system utilized one large field divided in half, one half of a field with crops and left the other half of a field was left unplanted for a year so as not to exhaust the soil. This system led to problems, because dividing the land in half led to shortages in the production of food because only half of the field was being used. This system of agriculture needed some minor adjustments to increase the production of food without destroying the soil i ....

.... make the least gas. The information that I discovered through this experiment I hope to use to increase my comprehension of baking techniques. Experimentation For the actual experiment, I used four (4) ICB root beer bottles, 4 balloons, yeast and the yeast foods- corn syrup, flour/water, gelatin, and grape juice. The yeast was a solution-6¾ teaspoons of yeast per cup of very warm (105° to 115°) water. Into all four bottles I put four tablespoons (tbsp.) of the yeast solution. Put ½ cup of corn syrup into bottle one, along with the yeast solution. Into bottle two goes ½ cup of water and ½ cup of flour, and the yeast solution. Next, mix the gelatin according ....

.... illnesses. In addition, this form of may possibly prove to be fitting in order to manufacture pharmaceutical drugs. On the other hand, Dolly has also brought forth disgust and dismay. animals reflects a lack of respect for the individual animal's integrity and that the application of such technology will result in undesirable shifts in our view of how we may treat animals and how radically we can meddle with nature in general. Furthermore, it is stressed that, whatever potential uses it may be put to at some future stage, the technique raises a long string of ethical problems. In addition, it may be feared that within a number of years the development and application ....

.... experience of the mother is viewed by physicians as pain: pain experienced and pain to be avoided.1 Having experienced childbirth ourselves, we have great compassion for women in painful labors. However, we also feel a responsibility to mothers and their babies to explore issues concerning the use of epidural anesthesia in labor issues that are seldom discussed prenatally. Several factors make the use of epidurals potentially hazardous. The Physician’s Desk Reference cautions that local anesthetics – the type used in epidurals – rapidly cross the placenta. When used for epidural blocks, anesthesia can cause varying degrees of maternal, fetal, and neonatal ....
