Behavioral Response of Amano Shrimp with a Predatory Stimulus

Amano Shrimp Evasion in Response to Predatory Stimulus This study observed the physical behavior of the crustacean Caridina multidentata, more commonly known as amano shrimp, and their response when introduced to a predation-like stimulus. This research sought to understand how amano shrimp are affected by the presence of fish and possible predation. This research carries significance as it could indicate whether the shrimp are affected by the water they’re in, and if that affects their capabilities to carry out their main commercial purpose. This study specifically looks at the amano shrimp and its ability to evade predation when exposed to a stimulus similar to that of a fish\u27s suction to obtain food. When amano shrimp are attacked by fish, the fish sucks water in rapidly to bring the shrimp into its mouth. The shrimp avoids the predation primarily through the use of their entire abdomen to push itself away from the suction. This motion is conducted with the use of leg-like extensions called pleopods and a uropod. Our research suggests there is a significant difference in evasion response when exposed to a predation stimulus while in fish contaminated water as opposed to clean water. The shrimp display a quicker response in fish contaminated water, and seem to be more cautious, as they display the response from further away

End point control of an actinide precipitation reactor

The actinide precipitation reactors in the nuclear materials processing facility at Los Alamos National Laboratory are used to remove actinides and other heavy metals from the effluent streams generated during the purification of plutonium. These effluent streams consist of hydrochloric acid solutions, ranging from one to five molar in concentration, in which actinides and other metals are dissolved. The actinides present are plutonium and americium. Typical actinide loadings range from one to five grams per liter. The most prevalent heavy metals are iron, chromium, and nickel that are due to stainless steel. Removal of these metals from solution is accomplished by hydroxide precipitation during the neutralization of the effluent. An end point control algorithm for the semi-batch actinide precipitation reactors at Los Alamos National Laboratory is described. The algorithm is based on an equilibrium solubility model of the chemical species in solution. This model is used to predict the amount of base hydroxide necessary to reach the end point of the actinide precipitation reaction. The model parameters are updated by on-line pH measurements

Financial Management Education: Its Role in Changing Behavior

Managing personal finances is a crucial but difficult issue. Many writers are concerned about whether or not Americans are prepared to handle their finances as personal debt and bankruptcies grow. While some educators believe that financial education can improve a family\u27s financial security, others question the effectiveness of such programs. The study reported here examined the results of Money 2000™ and its ability to influence behavior and financial preparedness. Participants made greater use of banks and less use of loan and check cashing services, increased savings, and decreased debt. The data supports financial literacy training as enhancing financial well-being

The World Wide Web: A Training Tool for Family Resource Management Educators

Cooperative Extension has actively explored new technologies as a means to provide education to its own staff and the general public. The study reported here concerned the development of a Web site used for Extension family resource management training. The study found that Extension educators use the Web for information and support using it for training. Educators appreciated having links that could be considered reliable and accurate. The data also suggest that such sites can provide a refresher to the in-service material, thus reinforcing the learning experience

Internet Standards: How One State\u27s Small Business Web Sites Compare to Expectations

Small business owners are increasingly realizing the importance of establishing an Internet presence. The purpose of the study reported here was to evaluate a sample of Web sites of small and often rural businesses and compare how well the Web sites met a set of 40 standards identified in the literature. In general, the Web sites scored well. The largest area of concern was the lack of variety of ways a customer could order or get assistance. Suggestions are provided as to how this information can be used by Extension educators
