Lysmata Rafa, A New Species Of Peppermint Shrimp (Crustacea, Caridea, Hippolytidae) From The Subtropical Western Atlantic, Andrew L. Rhyne, Arthur Anker

Arts & Sciences Faculty Publications

Lysmata rafa n. sp. is described from freshly collected specimens from the Keys West Lakes, Florida Keys, and from a museum specimen collected at Bear Cut, Biscayne Bay, Florida. The new species is morphologically most similar to the western Atlantic Lysmata rathbunae Chace, 1970 and the eastern PaciWc Lysmata gracilirostris Wicksten, 2000, but can be distinguished from them by the number of carpal segments in the second pereiopod; the length and dentition of the rostrum; the shape and number of spines on the dactylus of the third to Wfth pereiopods; and the absence of a tooth on the pterygostomial margin …

Density-Dependent Effect On Reproductive Behaviour Of Lysmata Amboinensis And L. Boggessi (Decapoda: Caridea: Hippolytidae), Dong Zhang, Andrew L. Rhyne, Junda Lin

Arts & Sciences Faculty Publications

We compared the reproductive behaviours of two protandric simultaneous hermaphroditic species (Lysmata amboinensis and L. boggessi) that belong to two groups of Lysmata shrimp with different morphology, geographical distribution, and density. Lysmata amboinensis occurs in tropical waters at low population densities, and L. boggessi is found in aggregation in sub-tropical and temperate areas. Reproductive behaviour of L. boggessi under two densities and L. amboinensis in different habitats were compared. Results show that L. amboinensis was much less active during mating than L. boggessi. Male shrimp of L. amboinensis did not display obvious pre-copulation behaviour. They also took …

This study aims to evaluate human papillomavirus (HPV) prevalence and predominating genotypes in liquid-based cervical cytology samples from an Irish urban female population. In addition to use of routine cervical cytology testing, women are screened for HPV using the MY09/11 primers for the HPV L1 gene and primers for β-globin amplification in a multiplex format. Overall, 996 women between the ages of 16 and 72 years (average age: 35) are included in the study and HPV prevalence was 19.8%. Cytology results showed that 88.9% were normal, 9% borderline or mild dyskaryosis, 1.1% moderate dyskaryosis and 0.9% severe dyskaryosis. Human papillomavirus …

The Effect Of Nutrition Information On Menu Selection When Eating Food Away From Home, Rebecca Foster Hochradel

Theses and Dissertations in Business Administration

As the number of Americans diagnosed with heart disease, diabetes, and excessive weight continues to increase, providing information to allow consumers to choose healthier foods becomes imperative. The number of consumers eating food away from home (EFAH) is rising. Although nutrition information is required on food products purchased for home use, it is not required when EFAH. How can a consumer know what is healthy if nutrition information is not provided? Policy makers and restaurateurs are in conflict regarding the provision of nutrition information on the menu. Policy makers want this information to be provided while restaurateurs say providing this …

Effect Of 28-Homobrassinolide On Salinity-Induced Changes In Brassica Juncea, Shamsul Hayat, Barket Ali, Syed Aiman Hasan, Aqil Ahmad

Turkish Journal of Biology

Seedlings of Brassica juncea Czern & Coss cv. Varuna generated from seeds soaked in 0, 50, 100, or 150 mM NaCl for 6 h were treated with 0, 10^{-10}, 10^{-8}, or 10^{-6} M 28-homobrassinolide (HBL) after 14 days of growth. Plants that received only NaCl treatment exhibited a decrease in nitrate reductase and carbonic anhydrase activity, chlorophyll content, and P_N 60 days after sowing (DAS), and decreased seed yield at harvest (140 DAS). Subsequent treatment with HBL significantly increased all of the above parameters. The 10^{-8} M concentration of HBL generated the best response and also overcame the detrimental effects …

Foraging Ecology Of Black-Crowned Night-Herons (Nycticorax Nycticorax) In The New York City Area, Andrew James Bernick

Dissertations, Theses, and Capstone Projects

Over 1,700 pairs of colonial wading birds (i.e., herons, egrets, and ibis) breed and forage in the industrialized ecosystem of metropolitan New York City (NYC). Wading bird colonies are located on 7 islands that lie between western Staten Island and Long Island Sound. The Black-crowned Night-Heron (BCNH), a mainly nocturnal forager, is the numerically dominant breeding heron in these colonies, and has been undergoing population declines both locally and region-wide since the mid-1990s. My objective was to determine how BCNHs forage in NYC's urban estuarine, freshwater, and terrestrial environments. From March-September 2002-2004, I conducted weekly night surveys on Staten Island, …

Development Of An Immunoturbidimetric Particle Enhanced Assay For Detection Of C-Reactive Protein, Maria Nicholas

Theses

Background: C-reactive protein (CRP) is a well-known marker for inflammation. Recent studies have demonstrated that increases in CRP concentrations are associated with future coronary events in apparently healthy men and women. The requirement for assays, capable of testing CRP concentrations within the range 1-lOmg/l, is therefore great.

Methods: Two CRP assays were developed. The Sensitive assay is capable of measuring CRP concentrations as low as lmg/l for use as a potential cardiac marker test. The Normal assay can measure concentrations from 5-400mg/l for establishing levels of inflammation. Both assays developed are latex particle enhanced immunoturbidimetric assays designed for use on …

Evaluation Of Four Novel Broad-Host-Range Antimicrobial Agents., Jiahui Guo

Theses

The overall objective of this thesis was to evaluate the antimicrobial effects of four novel broad-host-range antimicrobial agents. The first was a milk-derived lipoprotein developed by Westgate Biologicals with the support of Enterprise Ireland. This lipoprotein which was designated LactiSAL, was evaluated against a wide range of bacterial species associated with humans. Essentially, the LactiSAL was incorporated at a variety of concentrations into agar media, which were appropriate for cultivation of the different genera. Agars were examined for colony formation, after which it was possible to quantify the minimal inhibitory concentration for each genus. Subsequently, LactiSAL was incorporated at levels …

Cultivating The Civic Scientist: Science Communication & Tertiary Biotechnology Education, Joanne Edmondston

Theses: Doctorates and Masters

Biotechnology is one of the most rapidly growing industries of the 21st Century and governments worldwide have invested significant funds to support research and development in this area. The belief that the commercialisation of biotechnology will offer significant social and economic benefits to the communities investing in this industry, however, is not a universally accepted view. Surveys of attitudes towards biotechnology in a number of countries have indicated that there are widespread concerns about the risks presented by the industry and the application of biotechnology products (Smith, 2001). These public concerns have resulted in a stronger focus being placed on …

Comparison Of Three Survey Methods Applied To The Recreational Rock Lobster Fishery Of Western Australia., Tara Baharthah

Theses: Doctorates and Masters

A mail survey of recreational rock lobster licence holders has been conducted annually since 1986. The results from this survey have been used in the management of the recreational rock lobster fishery in Western Australia. Mail surveys are susceptible to non-response and recall bias. The key to determining useful estimates of fishing catch and effort is to minimise both biases. Telephone recall surveys, with high response rates, effectively eliminate nonresponse bias. However, they still suffer from recall bias when the recall period is greater than two months. Telephone diary surveys are free of non-response bias and recall bias and provide …

Multiple Mixed-Type Attractors In A Competition Model, J. M. Cushing, Shandelle M. Henson, Chantel C. Blackburn

Faculty Publications

We show that a discrete-time, two-species competition model with Ricker (exponential) nonlinearities can exhibit multiple mixed-type attractors. By this is meant dynamic scenarios in which there are simultaneously present both coexistence attractors (in which both species are present) and exclusion attractors (in which one species is absent). Recent studies have investigated the inclusion of life-cycle stages in competition models as a casual mechanism for the existence of these kinds of multiple attractors. In this paper we investigate the role of nonlinearities in competition models without life-cycle stages. © 2007 Taylor & Francis Group, LLC.

Simultaneous Modelling Of The Thermal Degradationa Kinetics Of Pectin, Daniel Rico, Ana Belen Martin-Diana, Catherine Barry-Ryan, Gary Henehan, Jesus Maria Frias

Articles

The thermal degradation kinetics of pectin methylesterase (PME) from carrot and lettuce were studied. Fresh extracts were exposed to temperatures from 55 to 70 °C until the enzyme was inactivated. A model based on the presence of two forms of the enzyme, one active and one non-active, is proposed. The natural variability of the PME activity was taken into the model in the form of normally distributed random effects. The common model parameters obtained (cleavage constant (0.0395±0.0062 s⁻¹), degradation constant (0.556±0.112 s⁻¹), cleavage energy of activation (469±23 kJ mol⁻¹) and degradation energy of activation …

Ef Fi Cacy Of Steamer Jet-Injection As Alternative To Chlorine In Fresh-Cut Lettuce, Daniel Rico, Ana Belen Martin-Diana, Jesus Maria Frias, J. Barat, Gary Henehan, Catherine Barry-Ryan

Articles

The use of calcium lactate solutions has been shown to be a healthy alternative to chlorine washing in order to maintain the shelf-life of fresh-cut products. The aim of this research was to analyse the effects of calcium lactate (15 g L⁻¹) treatment at 25 °C and 50 °C (heat-shock) on the textural properties of sliced carrots and to compare those with the chlorine treatment (120 mg L⁻¹) widely used in industry. Several direct and indirect markers of textural changes in carrots during storage were used: Instron textural analysis, Cryo-SEM and optical microscopic, sensory analysis, pectin …

Extending And Measuring The Quality Of Fresh-Cut Fruit And Vegetables: A Review, Ana Belen Martin-Diana, Daniel Rico, Gary Henehan, Jesus Maria Frias, J. Barat

Articles

The market sales of ready - to - use vegetables have grown rapidly in recent decades as a result of changes in consumer attitudes especially consumption of fresh-cut lettuce and carrot due to their use in prepared salads. Chlorine solutions have been widely used to sanitise fruit and vegetables in the fresh-cut industry. However, the association of chlorine with the possible formation of carcinogenic chlorinated compounds in water has called into question the use of chlorine in food processing. There is a real need to find alternatives for preservation of fresh-cut fruit and vegetables in order to improve the efficacy …

Good Things Come In Small Packages: Tiny Plankton Producing Oxygen Near Dead Zone, Abbie Basile

Libraries Faculty & Staff Publications

(First paragraph) For many, the words “Lake Erie” bring to mind large things: big sport fish, sprawling waterfront homes, and an enormous body of water bordering four states and two countries. Similarly, much of the Lake Erie research of which the public is aware deals with larger biological organisms—larger algae and zooplankton, the small fish that eat the zooplankton, and the large fish that feed on those smaller fish. Over the years, the smaller lake life have been somewhat overlooked.

Changes In Energy Expenditure With Ingestion Of High Protein, High Fat Versus High Protein, Low Fat Meals Among Underweight, Normal Weight, And Overweight Females., Amy Jo Riggs, Sareen S. Gropper, Barry D. White

Health Sciences & Kinesiology: Faculty Publications

Background: Metabolic rate is known to rise above basal levels after eating, especially following protein consumption. Yet, this postprandial rise in metabolism appears to vary among individuals. This study examined changes in energy expenditure in response to ingestion of a high protein, high fat (HPHF) meal versus an isocaloric high protein, low fat (HPLF) meal in underweight, normal weight, or overweight females (n = 21) aged 19–28 years.

Methods: Energy expenditure, measured using indirect calorimetry, was assessed before and every 30 minutes for 3.5 hours following consumption of the meals on two separate occasions. Height and weight were …

Infant Mortality Trends Among Georgia Residents, 1995-2003: Targeting Healthy People’S 2010 Goals, Diana Sturges, Laura H. Gunn, Padmini Shankar, Shrikrishna Shroff

Health Sciences & Kinesiology: Faculty Publications

Population-based trends in infant mortality among Georgia Residents between 1995 and 2003 were assessed on characteristics such as race, birth weight, neonatal and post-neonatal periods, and cause of death. A statistical analysis was conducted to show that the Georgia infant mortality rate (IMR) remained constant throughout the study period and averaged 8.67 per 1,000 live births. The analysis revealed racial disparities, with an IMR ranging from 6.03 in white infants to 13.76 in black infants, with less than one percent (0.86%) change, on average, among the differences between black and white mortality rates across the nine-year period. The disparities were …

Quantification Of Muscle Fatigue In Cerebal Palsy And Its Relationship To Impairments And Function, Noelle G. Moreau

LSU Doctoral Dissertations

Three experiments were designed to explore the measurement of muscle fatigue in people with cerebral palsy (CP). The four aims were to 1) develop a feasible and reliable isokinetic protocol to assess muscle fatigue of the knee flexors and extensors in this population, 2) determine if muscle fatigue of the knee flexors and extensors in people with CP differs from subjects without a motor disorder, 3) determine whether muscle fatigue is related to functional measures of activity and participation, and 4) investigate possible contributing factors of muscle fatigue. Results show that muscle fatigue can be reliably assessed through an isokinetic …

Self-Control Of Learning Multiple Motor Skills, Wilbur Fong Wah Wu

LSU Doctoral Dissertations

Learning is commonly referred to as a “two-way street” between the learner and instructor. Until recently, learning has been studied using a “one-way” approach in which numerous studies have explored learning in situations where the experimenter or instructor shapes the practice environment. A number motor learning studies have shown the effectiveness of the learners’ abilities to control various aspects within their learning environment. Studies on augmented feedback (Chiviacowsky & Wulf, 2002; Janelle, Kim, & Singer, 1995), observational learning (Wulf, Raupach, & Pfeiffer, 2005), and physical assistance devices (Wulf & Toole, 1999) have found that learning is enhanced when individuals are …

Culture-Independent Identification Of Gut Bacteria In Fourth-Instar Red Imported Fire Ant, Solenopsis Invicta Buren, Larvae, Albert Hon-Yu Lee

LSU Doctoral Dissertations

Red imported fire ants (RIFA), Solenopsis invicta Buren, are medical, urban, and agricultural pests from South America. Fourth-instar larvae are used by the colony to digest solid food and then regurgitate it for consumption by workers and queens. Larvae are an ideal source of investigations of obligate endosymbiotic bacteria possibly involved in nutrient distributions. I attempted to first identify what bacteria species are in the guts of larvae followed by antibiotic and microscopy work to further study their roles in the ants. The composition of the bacterial community in fire ant larvae was described with culture-independent methods utilizing 16S rDNA …

The Extent Of Interaction Between The Scallop And Prawn Fleets In The Shark Bay Scallop Managed Fishery, John Dickson

Theses : Honours

The Shark Bay Managed Scallop Fishery is Western Australia's most important scallop fishery with an annual value of between $2 and $58 million. In addition to this the fishery is an important source of regional employment with approximately 160 skippers and crew employed during the 2005 season. Two separate fleets are permitted to fish for scallops in this fishery, the first consisting of dedicated scallop fishing vessels (Class A licences) and the second of prawn fishing vessels (Class B licences) that are allowed to take scallops under a catch sharing arrangement. Concerns exist over the interactions between these two fleets …

The Value Of Oil Mallee Plantations And Revegetated Farm Land In The Southern Wheatbelt Region Of Western Australia For The Conservation Of The Western Pygmy Possum (Cercartetus Concinnus), Marie Short

Theses : Honours

Revegetation has the potential to enhance conservation of wildlife in rural environments, but few studies have tested whether the proposed benefits are realized. It is important to understand the role played by farm tree plantations in the landscape and how the potential biodiversity benefits may be enhanced without interfering with economic goals (Lamb, 1998). The adoption of oil mallee farming systems across the agricultural zone in south-west Western Australia is resulting in large areas of farmland being planted to native perennial tree species (Smith, 2004). While not planted for their conservation benefit, oil mallee systems may nonetheless enhance biodiversity. The …
