Impacts On Balance When Walking In Occupational Footwear, Harish Chander
Impacts On Balance When Walking In Occupational Footwear, Harish Chander
Electronic Theses and Dissertations
Hazards and challenges present in the workplace pose a number of potential risks for injuries and illness. Nearly 3.1 million nonfatal workplace injuries and illness were reported in 2010 (BLS, 2010). The probability of falls has been related to balance decrements. Further, an important point of distinction is 45% of all falls have been attributed to inappropriate footwear (Menant et al. 2008) Previous studies have shown decrements in balance as a result of different footwear (Menant et al. 2008) and after an increased workload over a specific period of time (Yaggie & McGregor, 2002; Gribble & Hertel, 2004). Occupational footwear …
Effects Of Hydrologic Connection On Physicochemical Conditions And Algal Properties In Backwaters Of The Lower Mississippi River, Orathai Pongruktham
Effects Of Hydrologic Connection On Physicochemical Conditions And Algal Properties In Backwaters Of The Lower Mississippi River, Orathai Pongruktham
Electronic Theses and Dissertations
In the last 50-100 years, the Mississippi River has been extensively engineered for flood control and navigation purposes. These modifications have substantially decreased the frequency of flooding and degree of contact of the river with its historical floodplain. However, in many areas within the current levee system there remain numerous secondary channels and other backwater sites with which the river is hydrologically connected on a seasonal basis. In this study, the relationships of surface hydrologic connection with the main channel of the Lower Mississippi River to limnological properties and development of phytoplankton biomass in three backwater sites having different patterns …
Adaptive Tolerance To Ocean Acidification In The Marine Sponge: Chondrilla Nucula, Sylvester Lee
Adaptive Tolerance To Ocean Acidification In The Marine Sponge: Chondrilla Nucula, Sylvester Lee
Electronic Theses and Dissertations
The dramatic increase in atmospheric carbon dioxide since the Industrial Revolution has led to a 30% increase in ocean acidification over pre-industrial levels. Although most ocean acidification research thus far has focused on calcifying organisms such as corals, the potential of this increase in acidity (H+ ions) to cause acid-base imbalances in soft-bodied animals such as sponges has been grossly overlooked. Furthermore, many studies on ocean acidification have not considered the elevated temperatures that are predicted to accompany future climate change conditions. Sponges are crucial components to coral reef systems, providing food, nutrients, structure, and support. The sponge Chondrilla nucula …
Fret Studies Of Dna Binding By Lambda Cro Variants, Lei Wang
Fret Studies Of Dna Binding By Lambda Cro Variants, Lei Wang
Electronic Theses and Dissertations
Proteins bind to DNA to form switches and circuits that control the flow of genetic information from DNA sequence to the physical components of cells and organisms. The dynamic performance of genetic switches depends on the coupling of the comprocesses of transcription and translation to protein-specific folding, assembly and binding reactions. For many model circuits protein dimerization and DNA binding are fast relative to the time scale of transcription and translation and thus amenable to modeling by statistical thermodynamics. In these cases, the distribution of proteins between monomers and dimers and between nonspecific and specific DNA complexes can be simply …
Survey Of The Native And Nonnative Vascular Plant Species Of Three Islands In Lake Winnipesaukee, New Hampshire, Mark Gardner Winkler
Survey Of The Native And Nonnative Vascular Plant Species Of Three Islands In Lake Winnipesaukee, New Hampshire, Mark Gardner Winkler
Electronic Theses and Dissertations
This study examined the long-term patterns in vascular plant composition on three islands in Lake Winnipesaukee, NH. It also tested the role of island biogeography in ecology as it analyzed the effectiveness of a land use plan implemented on the islands. Samplings were made on the islands in the summer of 2011 and were compared to earlier samplings in 1978, 1991, and 2001. The flora was observed and measured in 25 permanent plots that were established on the three islands in 1978. The understory flora was measured by presence and percent cover and the overstory was measured by frequency and …
Comparison Of Exercise And Eating In Collegiate Athletes Vs. Non-Athletes Active In High School Sports, Laura Leighton Blair
Comparison Of Exercise And Eating In Collegiate Athletes Vs. Non-Athletes Active In High School Sports, Laura Leighton Blair
Electronic Theses and Dissertations
Numerous studies have been conducted on eating disorders (ED) in collegiate athletes. Many studies conclude that collegiate athletes are more at risk of developing an ED compared to non-athletes, while some report the opposite. Purpose. To determine if collegiate athletes are more likely to exhibit ED characteristics compared to those who only participated in high school sports. Method. Each participant completed The Eating Attitude Test-26 (EAT), The Eating Disorder Inventory subscales Body Dissatisfaction (EDIBD), Drive for Thinness (EDIDFT), and Bulimia (EDIBUL) and The Body Shape Questionnaire-34 (BSQ). Group differences were examined for males (N=101), females (N=189), collegiate athletes (N=107), non-athletes …
Exposure Of Breastfeeding Education To Ob/Gyns Currently Practicing In The State Of Mississippi And Its Effect On Confidence In Providing Breastfeeding Support To Expectant Mothers, Brandi Lee Pigg
Electronic Theses and Dissertations
There are several well documented benefits of breastfeeding for the mother and child, however, Mississippi breastfeeding rates are lacking when compared to the rest of the United States. It is believed that breastfeeding encouragement and support from prenatal healthcare providers can play a major role in mothers choosing to initiate breastfeeding. OB/GYNs should be at the forefront of this initiative because they have repeat prenatal contact with many mothers. In order to provide breastfeeding encouragement and support to expectant mothers, OB/GYNs must have adequate breastfeeding education and the confidence to support these mothers. This study analyzed the amount of breastfeeding …
Mixing It Up: Multiple Symbiont Acquisition Strategies As An Adaptive Mechanism In The Coral Stylophora Pistillata, Kristen A. Byler
Mixing It Up: Multiple Symbiont Acquisition Strategies As An Adaptive Mechanism In The Coral Stylophora Pistillata, Kristen A. Byler
Electronic Theses and Dissertations
In obligate symbioses, the host's survival relies on the successful acquisition and maintenance of symbionts, which can be transferred from parent to offspring via direct inheritance (vertical transmission) or acquired anew each generation from the environment (horizontal transmission). Vertical transmission ensures progeny acquire their obligate symbionts, but progeny encountering an environment that differs from that of their parent may be disadvantaged by hosting a suboptimal symbiont. Conversely, horizontal symbiont acquisition provides hosts the benefit of acquiring symbionts well suited to the prevailing environment, but progeny may fail to acquire their obligate symbionts. Here I show that the coral Stylophora pistillata …
Valproic Acid-Induced Teratogenesis In Japanese Rice Fish (Oryzias Latipes) Embryogenesis, Mengmeng Wu
Valproic Acid-Induced Teratogenesis In Japanese Rice Fish (Oryzias Latipes) Embryogenesis, Mengmeng Wu
Electronic Theses and Dissertations
Valproic acid (VPA) was introduced as an antiepileptic in 1967 in France and it has become the most prescribed anticonvulsive drug therapy worldwide since then. In the clinic, valproic acid is selected to treat absence seizures, myoclonic seizures, generalized tonic-clonic seizures, atonic attacks and partial seizures. Epilepsy is the second most comneurologic disorder that affects pregnant women (0.5%–1%). Approximately 1 out of 250 pregnant women are taking antiepileptic drugs. Valproic acid is designated as a human teratogen, which induces major congenital anomalies, facial dysmorphic features, and autistic-like behaviors, which affect verbal, cognitive, communicative, and social abilities of affected children. We …
