How Does A Riverine Setting Affect The Lifestyle Of Shellmound Builders In Brazil?, Sabine Eggers, C. C. Petronilho, K. Brandt, C. Jericó-Daminello, J. Filippini, Karl Reinhard

Karl Reinhard Publications

The contact of inland and coastal prehistoric groups in Brazil is believed to have been restricted to regions with no geographical barrier, as is the case in the Ribeira de Iguape valley. The inland osteological collection from the riverine shellmound Moraes (5800–4500 BP) represents a unique opportunity to test this assumption for this region. Despite cultural similarities between riverine and coastal shellmounds, important ecological and site distribution differences are expected to impact on lifestyle. The purpose of this study is thus to document and interpret health and lifestyle indicators in Moraes in comparison to coastal shellmound groups. Specifically we test …

Determination Of Free Catecholamines In Urine By Tandem Affinity/Ion-Pair Chromatography And Flow Injection Analysis, David H. Thomas, Jay D. Taylor, Omar S. Barnaby, David S. Hage

David Hage Publications

Background—A system was developed for the simultaneous measurement in urine of free catecholamines (i.e., dopamine, norepinephrine, epinephrine) and creatinine (i.e., an indicator of urine output and volume). This method was based on the use of tandem affinity/ion-pair HPLC and flow injection analysis.

Methods—The free catecholamines were extracted directly from urine by using an on-line phenylboronic acid affinity column. The extracted solutes were then separated and measured by ionpair chromatography followed by amperometric detection. Creatinine was measured by an on-line flow injection analysis system based on the Jaffe reaction, which analyzed creatinine as it eluted nonretained from the phenylboronic …

Spiral Of Silence And The Iraq War, Jessica Drake

Theses

Discussing controversial issues may be hard for some individuals because they fear they may become isolated. The Iraq War serves as one such controversy in which some individuals might avoid publicly expressing their opinion. Spiral of silence, a communication theory set forth by Elisabeth Noelle-Neumann can be used to explain why some individuals will publicly express their opinion of the Iraq War while others will not. A Web-based survey was distributed to Rochester Institute of Technology faculty, staff and students. This study investigated public opinion expression through interactive forms of media such as discussion forums, blogs and Web sites.

St. Ambrose And The Architecture Of The Churches Of Northern Italy : Ecclesiastical Architecture As A Function Of Liturgy., Sylvia Crenshaw Schneider 1948-

Electronic Theses and Dissertations

This thesis argues that the architecture of the churches of northern Italy that were constructed during the fifth and sixth centuries reflected the influence and vision of Ambrose, bishop of Milan (374-397), whose spiritual authority, theologically and liturgically, militantly extended the ecclesiastical authority of the see of Milan. In particular, this thesis demonstrates that the hegemony of the see of Milan in northern Italy was implemented in the architectural accommodation of the distinctive Ambrosian liturgy of Milan. To develop this argument, this thesis has adopted an integrated approach to the political and ecclesiastical history of northern Italy in the fourth …

Experiences Influencing Degree Completion Articulated By Doctoral Students In Education Administration., David Lee Barnett

Electronic Theses and Dissertations

Educational literature indicates that approximately half of all doctoral students persist to degree completion. The literature indicates persistence rates among the social sciences are even lower. This study examined factors influencing doctoral student persistence in education administration programs. Tinto's theory of graduate student persistence framed four research questions: Do the demographics of doctoral students persisting to degree completion in education administration differ from those not completing their programs? Do doctoral students in education administration programs articulate experiences of academic integration as influencing their persistence? Do doctoral students in education administration programs articulate experiences of social integration as influencing their persistence? …

Altered Developmental Programming Of The Mouse Mammary Gland In Female Offspring Following Perinatal Dietary Exposures : A Systems-Biology Perspective., Caleb Deen Bastian

Electronic Theses and Dissertations

Mishaps in prenatal development can influence mammary gland development and, ultimately, affect susceptibility to factors that cause breast cancer. This research was based on the underlying hypothesis that maternal dietary composition during pregnancy can alter developmental (fetal) programming of the mammary gland. We used a computational systems-biology approach and Bayesian-based stochastic search variable selection algorithm (SSVS) to identify differentially expressed genes and biological themes and pathways. Postnatal growth trajectories and gene expression in the mammary gland at 10-weeks of age in female mice were investigated following different maternal diet exposures during prenatal-lactational-early-juvenile development. This correlated a decrease in expression of …

Modeling The Relationship Between Air Quality And Intelligent Transportation System (Its) With Artificial Neural Networks., Dinesh Kumar Gupta 1965-

Electronic Theses and Dissertations

Environmental or air quality impacts of Intelligent Transportation Systems (ITS) are very difficult to measure. Some researchers have attempted to quantify the effects of individual ITS application on emissions; yet, the effects of ITS as a whole on ambient air quality have not been investigated. The objective of this research was to model the relationship between ITS and ambient air quality. The multiple Artificial Neural Networks (ANN) training with the data yielded a model for predicting the air quality. In addition, the ANN made the measurement of the effect of ITS on air quality possible. Data pertaining to sixty US …

On The Mutual Information And Power Allocation For Vector Gaussian Channels With Finite Discrete Inputs, Chengshan Xiao, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, the mutual information and power allocation are discussed for vector Gaussian channels with finite discrete inputs. It is shown that the classic water filling and mercury-water filling policies, which are allocating power to a bank of independent parallel channels, may lead to significant loss compared to the original system without power allocation for finite discrete inputs. a generalized linear precoder, which is a non-diagonal and non-unitary matrix, is proposed for cross- channel power allocation to maximize the mutual information for vector channels. Numerical examples show that the new precoding-Based power allocation provides significant gain for a broad …

Proper Orthogonal Decomposition In The Generation Of Reduced Order Models For Interconnects, Wu Zhong Lin, Yao Jiang Zhang, Er Ping Li

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, reduced order models are generated using the technique of proper orthogonal decomposition (POD), also known as Karhunen-Loève decomposition (KLD) for the simulations of interconnect problems. Model order reduction is achieved by projecting the state-space of the original problems onto a subspace spanned by a few numbers of proper orthogonal modes (POMs) extracted by the POD procedure from an ensemble of system responses at a series of selected frequencies. the proper orthogonal values (POVs) corresponding to the POMs indicate the level of the importance of each POM and provide a guidance for the number of POMs to be …

Secure Virtual Backbone-Based Power Management For Ad Hoc Networks, Hung Yuan Hsu, Ali R. Hurson

Electrical and Computer Engineering Faculty Research & Creative Works

Power saving is a critical issue in wireless ad hoc networks. Many of the existing energy efficient routing protocols utilize the power management feature provided by MAC layer (e.g., IEEE 802.11 PSM). the rationale behind these protocols is to power down (put in sleep) the redundant nodes that do not involve in the packets routing. to keep a low end-to-end latency and preserve the routing fidelity, a group of nodes are selected to constitute a virtual backbone throughout the network. the backbone nodes do not sleep all the time serving for the packets routing while the rest of nodes turn …
