Prevention Of Angiotensin Ii-Induced Cardiac Remodeling By Angiotensin-(1-7), Justin L. Grobe, Adam P. Mecca, Melissa Lingis, Vinayak Shenoy, Tonya A. Bolton, Juline M. Machado, Robert C. Speth, Mohan K. Raizada, Michael J. Katovich

HPD Articles

Cardiac remodeling, which typically results from chronic hypertension or following an acute myocardial infarction, is a major risk factor for the development of heart failure and, ultimately, death. The renin-angiotensin system (RAS) has previously been established to play an important role in the progression of cardiac remodeling, and inhibition of a hyperactive RAS provides protection from cardiac remodeling and subsequent heart failure. Our previous studies have demonstrated that overexpression of angiotensin-converting enzyme 2 (ACE2) prevents cardiac remodeling and hypertrophy during chronic infusion of angiotensin II (ANG II). This, coupled with the knowledge that ACE2 is a key enzyme in the …

Preliminary Observations On The Reproductive Cycle And Uterine Fecundity Of The Yellow Stingray, Urobatis Jamaicensis (Elasmobranchii: Mylioba Tiformes: Urolophidae) In Southeast Florida, U.S.A., Daniel P. Fahy, Richard E. Spieler, William C. Hamlett

Marine & Environmental Sciences Faculty Articles

The yellow stingray, Urobatis jamaicensis is the most common elasmobranch observed among the coral reefs and associated habitats of Southeast Florida, U.S.A. In coastal waters off Broward County, Florida, gravid females were observed throughout the year. Urobatis jamaicensis is an aplacental viviparous species with evidence of a short gestation period (five to six months). Vitellogenesis occurs concurrently with gestation, with the females having both term fetuses and mature ova simultaneously. It is likely that the females have a bi-annual reproductive cycle where each female is capable of producing two broods annually. The ovulation period in the spring/summer reproductive cycle ranged …

K-41 Optimized Approximate Deconvolution Models, William Layton, Iuliana Stanculescu

Mathematics Faculty Articles

If the Navier-Stokes equations are averaged with a local, spacial convolution type filter, φ = gδ ∗ φ , the resulting system is not closed due to the filtered nonlinear term uu. An approximate deconvolution operator D is a bounded linear operator which satisfies

u = D(u) + O(δ α ),

where δ is the filter width and α ≥ 2. Using a deconvolution operator as an approximate filter inverse yields the closure

uu = D(u)D(u) + O(δ α ).

We derive optimal approximate deconvolution models for 3D turbulence. Specifically, we find the optimal parameters that minimize the time averaged …

On The Complete Join Of Permutative Combinatorial Rees–Sushkevich Varieties, Edmond W. H. Lee

Mathematics Faculty Articles

A semigroup variety is a Rees–Sushkevich variety if it is contained in a periodic variety generated by 0-simple semigroups. The collection of all permutative combinatorial Rees–Sushkevich varieties constitutes an incomplete lattice that does not contain the complete join J of all its varieties. The objective of this article is to investigate the subvarieties of J. It is shown that J is locally finite, non-finitely generated, and contains only finitely based subvarieties. The subvarieties of J are precisely the combinatorial Rees–Sushkevich varieties that do not contain a certain semigroup of order four.

Joint United States-Brazil Billfish Research In The Western South Atlantic, David W. Kerstetter, Fabio H.V. Hazin, J. C. Pacheco, John E. Graves

Marine & Environmental Sciences Faculty Reports

A joint research project between Brazilian and U.S. scientists was initiated in 2004 to investigate the interaction of istiophorid billfishes with pelagic longline fisheries in the western equatorial South Atlantic Ocean. This project incorporates two general themes (1) an investigation into several aspects of pelagic longline operations by comparing catch results between circle and “J” style hooks, time-of-capture with hook time recorders, and by direct monitoring of pelagic longline gear behavior, and (2) an additional evaluation of billfish trophic ecology using a combination of satellite tag technology and traditional analyses (e.g., gut contents and ageing). Data obtained from this research …

Post-Release Survival Of Sailfish (Istiophorus Platypterus) Captured On Commercial Pelagic Longline Gear In The Southern Gulf Of Mexico, David W. Kerstetter, John E. Graves

Marine & Environmental Sciences Faculty Reports

To estimate post-release survival of sailfish caught incidentally to regular commercial pelagic longline fishing operations in the southern Gulf of Mexico targeting mixed swordfish and tunas, ten pop-up satellite archival tags were deployed for ten days on incidentally captured animals. All ten tags transmitted following the full deployment period, transmitting 25-82% of the archived data. Repeated, short-duration movements at depth and horizontal displacement data from were consistent with survival of those nine of the ten animals for the ten-day deployment period. The results of this study indicate that sailfish can survive the trauma resulting from interaction with pelagic longline gear …

Preliminary Results Of Circle And J-Style Hook Comparisons In The Brazilian Pelagic Longline Fishery, David W. Kerstetter, J. C. Pacheco, Fabio H.V. Hazin, P. E. Travassos, John E. Graves

Marine & Environmental Sciences Faculty Reports

Preliminary studies in western North Atlantic pelagic longline fisheries indicate that a change in terminal gear from J-style hooks to circle hooks may reduce bycatch mortality. However, such studies have not examined the impact of this change in the equatorial fishery. Catch composition, catch rates, hooking location, and condition at haulback were monitored during 26 sets in the commercial longline fishery operating in the western equatorial South Atlantic where circle (size 18/0, non-offset) and J-style (size 9/0 and 10/0, 10° offset) hooks were deployed in an alternating fashion. Catch rates for yellowfin tuna, swordfish, and a composite “all fishes” category …

The Crinoid Fauna (Echinodermata: Crinoidea) Of Palau, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

Taxonomic revisions and a recent survey using scuba place the number of shallow-water (< 50 m) crinoid species known from Palau at 22. Five are new records: Clarkcomanthus littoralis, Comanthus suavia, Alloeocomatella pectinifera, Oxycomanthus comanthipinna, and O. exilis. A submersible survey (to 310 m) recovered five additional new records, four of which are the first representatives of their families from Palauan waters:Eudiocrinus venustulus (Eudiocrinidae), Glyptometra sp. (Charitometridae), Cosmiometra belsuchel Messing, n. sp. (Thalassometridae), and Porphyrocrinus verrucosus(Phrynocrinidae), the first stalked crinoid recorded from Palau. Two of the three specimens of the latter have regenerating crowns, suggesting that this species may be subject to substantial predation or an …

Surface Associated Amoebae On The Ctenophore, Mnemiopsis Sp., Connie S. Versteeg

HCNSO Student Theses and Dissertations

Previous work by Moss et al. (2001) reported surface associated protists on the ctenophore Mnemiopsis sp. They frequently observed the ciliate Trichodina ctenophorii and a Flabellula-like amoeba attached to the comb plate surface. They noted that the ciliate and the amoeba were found on the subsagittal, subtentacular, and the auricular comb plates. The amoeba had a maximum width of about 15 μm and cells were crescent shaped. Ultrastructural evidence suggested that these protists were parasites although the exact nature of the association remained to be determined. This was the background for the present study.

The present investigation documented the …

Comparison Of Fish Assemblages Between Mitigation Boulder Reef And Neighboring Natural Hardbottom In Broward County, Florida, Usa, Jessica A. Freeman

HCNSO Student Theses and Dissertations

A beach renourishment project was initiated in May 2005 and completed in February 2006 to restore 11.1 km of shoreline in Broward County, Florida, USA. For mitigation of predicted nearshore hardbottom burial, a boulder reef totaling 3.6 ha was deployed in 2003. To examine the replacement value of the mitigation relative to fishes, this study compared fish assemblages on boulder reef to those on adjacent natural hardbottom. Twenty-five natural hardbottom sites and twenty-five boulder reef sites were surveyed six times between March 2005 and August 2007. Two non-destructive visual census methods, a transect count (30 m long x 2 m …

An Analysis Of It/Is Offshore Outsourcing: Educator Perspectives, Martin H. Bagaya

CCAC Theses and Dissertations

IT/IS Offshore outsourcing is defined as a commercial arrangement of transferring local ITIIS functions, assets, activities, products and services to a foreign contractor therefore removing new employment positions, replacing or displacing U.S. domestic IT/IS workers with those from other countries for financial or competitive advantage of the outsourcing client. This process of offshore outsourcing to overseas locations was perceived to have consequences on IT/IS student enrolment at U.S. universities.

The objective of this study was to identify administrators' responses to reduced IT/IS student enrolments. The majority of ITIIS college administrators have concerns about offshore outsourcing, and is perceived to reduce …

Electronic Performance Support For E-Learning Analysis And Design, Thomas W. Jury

CCAC Theses and Dissertations

Corporate instructional designers often follow an instructional systems design (ISD) process to plan, create, and implement training programs. Increased demand for elearning as a replacement or addition to classroom training means that, in the current corporate environment, instructional designers are called upon to produce a wide variety of instructional formats and have to make more decisions during the ISD process.

E-learning is evolving into a total performance improvement solution rather than simply as a means to delivering distance training and consequently, in an effort to achieve business goals, many corporations are turning to it as a cost effective way to …

Measuring The Effect Of E-Learning On Job Performance, Heidi Kramer

CCAC Theses and Dissertations

E-learning is becoming a leading delivery method in workplace-learning settings across organizations of various sectors and of varying sizes. The ultimate goal is to drive business results. Managers need to provide evidence of a positive impact on corporate strategy and investment objectives. If the business goal cannot be identified, there should be a query on why it is there in the first place. Transfer of the knowledge learned in the training session to the work situation is not built into most skills training delivery, especially those provided through e-learning. The outcomes and the effects of training on job performance are …

Painting The Voice: Weblogs And Writing Instruction In The High School Classroom, Marilyn V. Olander

CCAC Theses and Dissertations

Writing is a complex cognitive skill, a technology for capturing speech whose forms and conventions began in the dawn of civilization and were in place and stable by the Middle Ages. Writing and reading are the foundation of literacy, fundamental to success in school and in the adult world. No comprehensive theory of composition guides the teaching of writing, although historically two approaches have been favored: writing as a skill acquired through the memorization and recognition of principles of grammar and usage, and more recently, writing as a process of recursive strategies of pi arming, drafting, revising, editing, and publishing. …

Measuring Factors That Influence The Success Of E-Government Initiatives, Ronnie Park

CCAC Theses and Dissertations

The success of e-government initiatives is contingent upon its citizens ' willingness to use the services. Citizens are more likely to use e-government services if they believe that they get better value than from the conventional government services. Understanding how citizens value e-government services is critical to the success of these initiatives. This study utilizes two concepts from the field of decision analysis. These are mean-ends chains and value-focused thinking. The research that follows describes the development of a model to identify factors that influence value judgments of citizens.

Based on the data of 21 0 responses from e-government service …

Performance Measurement For The E-Government Initiatives: A Comparative Study, Willy C. Isaac

CCAC Theses and Dissertations

The main objective of performance measurement in public organizations is to support better decision-making by management, leading to improved outcome for the community, and to meet external accountability requirements. There are different performance measurement models to measure the e-Government initiatives and different studies differ in identifying the key factors and measurement indicator. Many measurement instruments take a too simplistic view and focus on measuring what is easy to measure. Much challenge faced by the existing e-Government studies is understanding what citizens, businesses and government agencies wants and how to measure the return on government's Internet investment. Government administrations, international organizations …
