The question that was being looked into is “what is the quality of the U-High Creek based on invertebrates found in the water?” The number and types of invertebrates found in the water helped us to determine the water quality of the U-High Creek. This being said, data was collected by collecting aquatic invertebrates in the creek and identifying the number and types of invertebrates found. The original prediction was the water quality of the U-High Creek is fair. The water quality of the creek was actually excellent, thus the original prediction was rejected. Overall, there came out to be 19 different types of invertebrates and 460 in total. Since the number and types of invertebrates found in the samples are so high, the water quality has to be excellent for each of the groups to survive and thrive. Out of the 19 different types of invertebrates, 7 of them were pollution sensitive. …show more content…
If the water quality was poor or fair, the organisms in the pollution sensitive group wouldn’t be able to survive. At the creek, all the grass was green and there were multiple different types of weeds and grasses growing around the creek. All of the plants appeared to be alive. Also there was a very little amount of trash and litter in and around the water. Plants need clean water to be able to spread and grow. Some of the plants would die off if the water was polluted. In addition, the water quality wouldn’t have been excellent if there was a significant amount of trash and litter in and around the creek. The litter would’ve broke down and chemicals would’ve found there way into the creek. The water quality index of the creek came out to be 36. Water quality index is measured based off of the number and type of invertebrates found in water. Anything above 23 in the water quality index is considered to be excellent, therefore the water quality is

Case Study Arc Solutions Provides a Centrally Controlled Operator Center Solution to Heffernan Group

...Case Study Arc Solutions Provides a centrally controlled operator center solution to Heffernan Group s o l u t i o n s The Challenges With an overall emphasis on customer service excellence, communication both internally and with customers has always been a key element to the success of the company. Whilst effective, this solution was not ideal as the company’s main aim was to ensure that all customers were dealt with personally by the operators. Having separate telephone systems serving each site also provided challenges, with the infrastructure being inflexible and a high systems management overhead. It also meant that operators had to be deployed to cope with the incoming traffic of that particular branch office, with no capability to share the load with other offices in busier times. Heffernan therefore decided to move to a single centralized communications platform, serving all sites. They chose Cisco Unified Communications technology as it delivered the power, flexibility and reliability to serve the whole business and its customers, both now and in the future. Whilst this provided an excellent platform for unifying communications across the enterprise, Profile Heffernan Insurance Brokers, formed in 1988, is one of the largest independent insurance brokerage firms in the United States. Heffernan provides comprehensive insurance and financial services products to a wide range of businesses and individuals. Headquartered in Walnut Creek, California, Heffernan has...

The following study is based on 26 utilities which burn coal, have a generating capacity of at least 50 Megawatts (MW) and whose Flue Gas Desulfurization devices have been operating for at least 5 years. An analysis is made of the capital and annual costs of these systems using a comparison of four main processes: lime, limestone, dual alkali and sodium carbonate scrubbing. The functional analysis, based on operability, allows a readjustment of the annual costs and a determination of the main reasons for failure. Finally four detailed case studies are analyzed and show the evolution of cost and operability along the years.

Hazing

...com 2). However, this is not what really happens. The acts often cross the line, and the victims do not complain because they want to join the group (Facts.com 2). Teens often want to outdo one another; each year, teens do something more dangerous then what happened to them while they were the victims (Bowers 1; Bushweller 3). Not only can these acts be dangerous, but they are also an “abuse of power and [a] violation of human dignity” (High School Hazing). If teens can be educated that this hurtful and inhumane act of bullying is forbidden in high school, then they will know that it is not acceptable in college, where hazing becomes the most dangerous. Although high school hazing starts out and seems harmless, it can quickly escalate to being harmful, dangerous, and illegal. Hazing can very quickly turn from a harmless prank into a dangerous situation. In most cases, the victim will still take part because they want to join the group. Take for instance, Casey Culpepper. She wanted to join the volleyball team her first year in high school. All through the summer, the threat of the "initiation" haunted her. One day she and her friends were attacked by seniors after class and smeared with concoctions that included canned dog food, eggs, ketchup, mustard, horse manure and pet...

...Natural Life Support Processes Issues in Ecology Number 4 Fall 1999 Biodiversity and Ecosystem Functioning: Maintaining Natural Life Support Processes by Shahid Naeem, Chair, F.S. Chapin III, Robert Costanza, Paul R. Ehrlich, Frank B. Golley, David U. Hooper, J.H. Lawton, Robert V. O’Neill, Harold A. Mooney, Osvaldo E. Sala, Amy J. Symstad, and David Tilman Critical processes at the ecosystem level influence plant productivity, soil fertility, water quality, atmospheric chemistry, and many other local and global environmental conditions that ultimately affect human welfare. These ecosystem processes are controlled by both the diversity and identity of the plant, animal, and microbial species living within a community. Human modifications to the living community in an ecosystem – as well as to the collective biodiversity of the earth – can therefore alter ecological functions and life support services that are vital to the well-being of human societies. Substantial changes have already occurred, especially local and global losses of biodiversity. The primary cause has been widespread human transformation of once highly diverse natural ecosystems into relatively species-poor managed ecosystems. Recent studies suggest that such reductions in biodiversity can alter both the magnitude and the stability of ecosystem processes, especially when biodiversity is reduced to the low levels typical of many managed systems. Our review of the available evidence has identified the...

An operational version of KPS, at a weekly level of detail, helps determine where products are produced and how finished products and in-process products are shipped between plants and distribution centers. A tactical version of KPS, at a monthly level of detail, helps to establish plant budgets and make capacity-expansion and consolidation decisions. Operational KPS reduced production, inventory, and distribution costs by an estimated $4.5 million in 1995. Tactical KPS recently guided a consolidation of production capacity with a projected savings of $35 to $40 million per year.

Co-operation is customary and instinctive solidarity. The first co-operative act of man was when the first human family started gathering food even before agriculture was invented (Mbat, 2000). The more advanced forms of traditional co-operation is demonstrated in saving and lending, joint action, joint possession of land. They did not leave life’s risks and emergence to chances. They developed various patterns of mutual assistance, reduced them to custom, and handed them down as tradition and as a legacy from the past through formal and informal education. 1.2 BACKGROUND TO THE STUDY All over the world, cooperatives are instrumental in social and...

This focus on external equity enables a ,company to develop compensation structures and programs that are competitive with other companies in appropriate labor markets. Perceptions of equity can also influence a company's abil­ ity to attract, retain, and motivate its employees. Employee perceptions of equity and inequity are equally important and should be carefully considered when a company sets compensation objectives. Employees who perceive equitable pay treatment may be more motivated to perform better or to sup­ port a company's goals. Individual employees, however, perceive equity in many different ways. Therefore, it is difficult to specify one definition of equity that is ap­ plicable to all s i t u a t i o n s .
