Decontamination Protocols For Watercraft And Wildland Firefighting Equipment In Preventing The Spread Of Invasive Quagga (Dreissena Rostriformis Bugensis) And Zebra (Dreissena Polymorpha) Mussels, Ashlie Watters Dec 2014

Decontamination Protocols For Watercraft And Wildland Firefighting Equipment In Preventing The Spread Of Invasive Quagga (Dreissena Rostriformis Bugensis) And Zebra (Dreissena Polymorpha) Mussels, Ashlie Watters

UNLV Theses, Dissertations, Professional Papers, and Capstones

Quagga and zebra mussels (Dreissena rostriformis bugensis and Dreissena polymorpha) are two invasive species introduced via ballast water discharged by large oceanic cargo ships to the North American Great Lakes in the late 1980s. Once established, the mussels spread quickly. In January 2007, D. rostriformis bugensis was discovered in Lake Mead, NV-AZ, and in that same year, mussels were confirmed further south on the Colorado River in Lakes Mojave and Havasu. Dreissenids clog water intake pipes, water filtration systems, and electric generating plants. The mussels also ruin boat motors, damage recreational equipment, and once established in the reservoir, routine maintenance …


Evaluating The Impact Of A Home-~Based Childhood Asthma Intervention Program In Clark County, Nevada, Mackenzie Suzanne Burns May 2014

Evaluating The Impact Of A Home-~Based Childhood Asthma Intervention Program In Clark County, Nevada, Mackenzie Suzanne Burns

UNLV Theses, Dissertations, Professional Papers, and Capstones

Asthma is a chronic, incurable, costly, and potentially life–threatening disease that affects an estimated 7 million children in the United States; further, more than 56,000 Nevada children are currently living with asthma. The literature suggests that a number of factors that contribute to either the development of asthma or the exacerbation of asthma symptoms in sensitive individuals can be traced to the home environment. Given that the majority of Americans spend over 90% of their time indoors, of which two–thirds are spent at home, a home–based childhood asthma intervention program represents a unique primary prevention opportunity. This pre–experimental study evaluated …


Development Of A Molecular Method For Detecting The Causative Agent Of Swimmer's Itch (Trichobilharzia) In Freshwater Ecosystems, Heidi Mcmaster May 2014

Development Of A Molecular Method For Detecting The Causative Agent Of Swimmer's Itch (Trichobilharzia) In Freshwater Ecosystems, Heidi Mcmaster

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cercarial dermatitis, commonly known as swimmer's itch, is caused by penetration of larvae of the schistosome,Trichobilharzia, into the dermis and epidermis layers of the skin. Symptoms are characterized by painful swelling and itching at the site of penetration. The normal hosts for the life cycle of the schistosome are aquatic birds and aquatic snails. The most frequently used method of detection forTrichobilharziais microscopy. With increases in the occurrence of cercarial dermatitis outbreaks in freshwater in the Southwestern United States, it is becoming increasingly important to develop and standardize a molecular method for rapid detection that can assist health professionals and …


Health Hazards In Rental Housing: An Overview Of Clark County, Nevada, Amanda Nicole Sokolowsky May 2014

Health Hazards In Rental Housing: An Overview Of Clark County, Nevada, Amanda Nicole Sokolowsky

UNLV Theses, Dissertations, Professional Papers, and Capstones

A wide range of health conditions are associated with housing conditions, including asthma, respiratory infections, injuries, mental health issues, and lead poisoning. People in modern societies spend more than 90% of their time indoors, the vast majority of which is spent at home. Therefore, any new information on housing related health hazards in a population provides an opportunity for a new prevention program. Reports have shown that rental properties have more health related hazards than owner occupied housing, and rental properties are frequently occupied by low-income and minority individuals. This descriptive study intended to provide an overview of housing related …
