Disinfection Of Dentin By Intracanal Laser Irradiation: An In Vitro Model, Silvia Cristina Mafra Cecchini

Loma Linda University Electronic Theses, Dissertations & Projects

A possible cause for root canal failure is the persistence of bacteria that have colonized dentinal tubules. To reduce this risk and, if possible, to also shorten the time consuming endodontic therapy, new equipment and materials are constantly being introduced. The aim of the present investigation was to study the effect of disinfection of dentinal tubules by intracanal laser irradiation using an in vitro model. The groups irradiated by various lasers were compared with calcium hydroxide, a material frequently used as intracanal medication between appointments. Freshly extracted, intact bovine incisors were used. The root cementum was removed and the teeth …

Antidepressent Treatment For Depression: Total Charges And Therapy Duration, Deborah G. Dobrez, Catherine A. Melfi, Thomas W. Croghan, Thomas J. Kniesner, Robert L. Obenchain

Center for Policy Research

Background: The economic costs of depression are significant, both the direct medical costs of care and the indirect costs of lost productivity. Empirical studies of antidepressant costeffectiveness suggest that the use of selective serotonin reuptake inhibitors (SSRI) may be no more costly than tricyclic antidepressants (TCA), will improve tolerability, and is associated with longer therapy duration. However the success of depression care usually involves multiple factors, including source of care, type of care, and patient characteristics, in addition to drug choice. The cost-effective mix of antidepressant therapy components is unclear.

Aims of the Study: Our study evaluates cost and antidepressant-continuity …

Developmental, Psychosocial, And Economic Predictors Of Healthy Newborns In Michigan’S Teenage Pregnancies, Cheryl Lauber

Dissertations

Teenage pregnancy is a critical health indicator. Using a risk reduction model, this study examined the relationship between the characteristics o f the teenage mother i and her newborn. The research questions were: ( I) what risk factors are associated with poor birth outcomes, (2) is addressing each factor the best way to reduce the risk, and (3) has the overall risk changed as the birth rate has declined? Developmental, psychosocial and economic risks were identified as independent variables, while age and race were mediators.

Combining the birth certificate records of women under age 20 from 1990 through 1997 resulted …

Dealing With A Dry Season, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Farmers' approaches to adverse seasonal conditions whether they be frost, flood or low rainfall should be to acquire as much information as possible on the immediate agronomic and financial situations and make a judgement on the longer term implications for the following seasons. Once the information has been acquired, in consultation with advisers, it is necessary to construct and implement agronomic and business strategies to deal with individual situations.

The agronomic and stocking options for the dry season supplied in this booklet deal with questions and issues arising from the Year 2000 season, which has been characterised by a mid …

The Toxicology Of Aluminum In The Brain: A Review, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Aluminum is environmentally ubiquitous, providing human exposure. Usual human exposure is primarily dietary. The potential for significant Al absorption from the nasal cavity and direct distribution into the brain should be further investigated. Decreased renal function increases human risk of Al-induced accumulation and toxicity. Brain Al entry from blood may involve transferrin-receptor mediated endocytosis and a more rapid process transporting small molecular weight Al species. There appears to be Al efflux from the brain, probably as Al citrate. There is prolonged retention of a fraction of Al that enters the brain, suggesting the potential for accumulation with repeated exposure. Al …

The Prevalence-Based Need For Adapted Physical Education Teachers In The United States, Jiabei Zhang

Human Performance and Health Education Faculty Research

The purpose was to develop a method for projecting the need for adapted physical education (APE) teachers in the public schools in the United States. This method was derived from a prevalence-based model---dividing the nurn- ber of APE students enrolled by the APE student-teacher ratio and then sub- tracting the number of APE teachers hired. This model used the findings of Kelly and Gansneder (1998) that (a) 4% of the school population required APE services and (b) the overall national APE student-teacher ratio was 104: 1. The results revealed a need for 22,116 additional APE teachers nationwide as well as …

Primate Numerical Competence: Contributions Toward Understanding Nonhuman Cognition, Sarah T. Boysen, Karen I. Hallberg

Sentience Collection

Nonhuman primates represent the most significant extant species for comparative studies of cognition, including such complex phenomena as numerical competence, among others. Studies of numerical skills in monkeys and apes have a long, though somewhat sparse history, although questions for current empirical studies remain of great interest to several fields, including comparative, developmental, and cognitive psychology; anthropology; ethology; and philosophy, to name a few. In addition to demonstrated similarities in complex information processing, empirical studies of a variety of potential cognitive limitations or constraints have provided insights into similarities and differences across the primate order, and continue to offer theoretical …

Signal Modeling With Non-Uniform Time Sampling Of Features For Automatic Speech Recognition, Montri Karnjanadecha

Electrical & Computer Engineering Theses & Dissertations

This dissertation presents an investigation of non-uniform time sampling methods for spectral/temporal feature extraction in speech. Frame-based features were computed based on an encoding of the global spectral shape using a Discrete Cosine Transform. In most current “standard” methods, trajectory (dynamic) features are determined from frame-based parameters using a fixed time sampling, i.e., fixed block length and fixed block spacing. In this research, new methods are proposed and investigated in which block length and/or block spacing are variable. The idea was initially tested with HMM-based isolated word recognition, and a significant performance improvement resulted when a variable block length and …

A Comparison Of Four Curing Lights For Bonding Of Orthodontic Brackets, David Sy Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Light cured adhesives have gained more popularity since their introduction more than three decades ago. Photo-polymerization allows more thorough curing on demand and thus facilitates better control of bracket placement. With new technologies, recently developed curing lights promise even more improvement. These systems are not only more sophisticated, but also more sensitive to the types of resins and clinical application. Specific comparison studies of the new systems in the orthodontic bonding are lacking because most of curing lights are originally designed for general dentistry.

This study evaluated the in-vitro ability of four curing lights to polymerize the Transbond XT bonding …

An Extension Of Euclidean Distance Matrix Analysis Applied To Craniofacial Growth Prediction, Mark K. Batesole

Loma Linda University Electronic Theses, Dissertations & Projects

This study is [sic] introduces a new extension of Euclidean Distance Matrix Analysis (EDMA) as applied to growth prediction analysis. Using EDMA eliminates the presupposition of a set growth pattern, which is introduced by traditional superimposition techniques. When EDMA is extended to analyze prediction methodologies, using a non-age-matched growth sample, some shortcomings become evident. These involve bootstrapping techniques, relative difference in growth, and absence of clinical, real world measure. To overcome these issues, a statistical approach using the Wilcoxen signed rank test, absolute difference in growth, and a new method to evaluate the error in a prediction methodology's landmark identification …

Conflicting Bureaucracies, Conflicted Work: Dilemmas In Case Management For Homeless People With Mental Illness, Linda E. Francis

The Journal of Sociology & Social Welfare

This ethnographic study finds a case management agency torn between the rules of two conflicting bureaucracies. Funded by a federal grant, the agency is administered by the county, and the regulations of the two systems turn out to be incompatible. This conflict creates dilemmas in providing services to clients: meeting eligibility criteria for services from the federal grant meant the clients did not meet the eligibility criteria for many County services. Agency staff reacted to this dilemma by bending rules, finding loopholes, and investing extra time and emotional labor in each client. The role-conflict engendered by bureaucratic disjunction creates frustration, …

Accommodationg Nursing Students With Learning Disablities, Debrayh Gaylle

Master's Projects

This study examined factors that facilitated or hindered the process of accommodating learning disabled nursing students in the classroom. Surveys were mailed to 300 faculty at associate and baccalaureate degree schools of nursing. The survey focused on faculty members' degree of ease or difficulty in providing accommodations, their perceptions of the adequacy of institutional support, and their own beliefs and understanding of the accommodation process. Analysis of the 109 returned surveys suggest the majority of faculty understood the need for accommodations. The majority of respondents stated they received adequate support from their respective institutions and were able to provide the …

Decision Support Methods In Diabetic Patient Management By Insulin Administration Neural Network Vs. Induction Methods For Knowledge Classification, B. V. Ambrosiadou, S. Vadera, Venky Shankaraman, D. Goulis, G. Gogou

Research Collection School Of Computing and Information Systems

Diabetes mellitus is now recognised as a major worldwide public health problem. At present, about 100 million people are registered as diabetic patients. Many clinical, social and economic problems occur as a consequence of insulin-dependent diabetes. Treatment attempts to prevent or delay complications by applying ‘optimal’ glycaemic control. Therefore, there is a continuous need for effective monitoring of the patient. Given the popularity of decision tree learning algorithms as well as neural networks for knowledge classification which is further used for decision support, this paper examines their relative merits by applying one algorithm from each family on a medical problem; …

The Next Step, Benjamin Y. Dai, Lynn Thompson, John David N. Dionisio, Hooshang Kangarloo, Ricky K. Taira

Computer Science Faculty Works

In traditional radiology practice, reports are typically dictated and then transcribed.? While the free-text reports represent the semantic knowledge interpreted and conveyed by a physician, the information can be hard to access. The advantages of representing medical data in a structured format using standard terminology are clearly recognized. These include the ability to implement a standardized electronic medical record, automatically invoke medical guidelines when appropriate, and conduct outcomes research. Standard structured reports facilitate intelligent indexing, searching, and retrieval of documents from clinical databases. Recent attempts have been made in the industry to enable structured data entry using preformatted templates, but …

Kenneth Starr: Diabolically Evil?, Jeanne L. Schroeder, David G. Carlson

Articles

The article explores the intersection of law, morality, and subjectivity through the lens of Slavoj Žižek's philosophical works, particularly in the context of the impeachment of President Clinton. It argues that the public's negative reaction to the impeachment was rooted in a fear of encountering "diabolical evil," a concept drawn from Kantian philosophy, where law and morality coincide perfectly. This form of evil is more terrifying than ordinary evil because it is committed without pathological motives, purely for the sake of duty.

An Object-Oriented Approach To The Modeling And Visualization Of Breast Cancer Tumors, Bruce C. Jenkins

Theses and Dissertations

Great strides have been made in controlling the progression of breast cancer, but medical professionals continue to rely primarily upon traditional mammography for early detection. Enhancing breast cancer detection capabilities - and thus reducing tumor detection time - should result in a reduction in mortality rates. The detection capabilities of mammography may be enhanced through improved modeling and visualization techniques. This thesis is an extension of initial research conducted at the Air Force Institute of Technology. Previous efforts focused on developing a mathematical model for simulating the growth of cancer within unconstrained 3-dimensional space. The research also explored the behavior …
