description: The salinity of the soils is one of the main causes of displacement and rearrangement of crop production. Bean cultivation is intolerant to salinity conditions by sodium
 chloride (NaCl). The selection of cultivations of tolerant beans to the salinity is an alternative to recover the production of the grain in the affected areas. This work was carried out with the objective of determining the effect of NaCl on the germination of different bean cultivars. For the selection, they used the seeds of 12 cultivars that were established in Petri dishes with the concentrations of 0, 100, 200, 300, 400,500 and 600 μmol L-1 of NaCl, in H2O and in soil. To the seed, they determined the imbibition, electrolytes leakage, germination and emergency. The results showed affectation in the germination and emergency with the increment of the concentration of NaCl in H2O and in soil. The line 40.3, line 40.4, line 40.8, line 64.1, line 64.7, line 84.4, line 84.6
 and line 84.9, had the least loss of water and electrolytes, with the major germination percentages and emergency in the salinity condition. The cultivars V-53, V-50, I-39
 and V-9, presented the greatest loss of water, the lowest germination, loss of electrolytes and emergency in saline conditions, which shows the low tolerance to salinity conditions.

description: We have investigated the structural, electronic, and magnetic properties of the pyrochlore iridates Eu2Ir2O7 and Pr2Ir2O7 using a combination of resonant elastic x-ray scattering, x-ray powder diffraction, and resonant inelastic x-ray scattering (RIXS). The structural parameters of Eu2Ir2O7 have been examined as a function of temperature and applied pressure, with a particular emphasis on regions of the phase diagram where electronic and magnetic phase transitions have been reported. We find no evidence of crystal symmetry change over the range of temperatures (~6 to 300 K) and pressures (~0.1 to 17 GPa) studied. We have also investigated the electronic and magnetic excitations in single crystal samples of Eu2Ir2O7 and Pr2Ir2O7 using high resolution Ir L3-edge RIXS. In spite of very different ground state properties, we find these materials exhibit qualitatively similar excitation spectra, with crystal field excitations at ~3-5 eV, spin-orbit excitations at ~0.5-1 eV, and broad low-lying excitations below ~0.15 eV. In Eu2Ir2O7 we observe highly damped magnetic excitations at ~45 meV, which display significant momentum dependence. We compare these results with recent dynamical structure factor calculations.

Do Relationships Last? Contrasting Peer Effects of 'Old' and 'New' Classmates

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: This study examines whether there exists any heterogeneity in peer effects based on whether or not students were in the same classroom in the previous time period or not. An individual's peer group can be divided into two; students with whom the individual was in the same classroom at time t-1, and those students with whom the individual was not in the same classroom at time t-1. This paper will discern whether there are differences in the impact of peer effects on an individual by these two different groups of students; i.e. whether an individual is affected more (in terms of academic outcomes) by his 'old' peers or by his 'new' peers. I construct panel data from data collected by the North Carolina Education Research Data Center and concentrate on elementary school children in grades 3-5. The study uses the linear-in-means model and controls for non-random sorting into peer groups with time constant unobserved covariates. I find
that non-random sorting into peer groups diminishes peer effects and are thus important for estimations of peer effects. I also find no difference in the multipliers produced by these two groups of students, indicating that it does not matter whether or not a peer's individual is 'old' or 'new'. Further research may be carried out to test for heterogeneity using longer periods of interactions among the students.

description: Distributed desynchronization algorithms are key to wireless sensor networks as they allow for medium access control in a decentralized manner. In this paper, we view desynchronization primitives as iterative methods that solve optimization problems. In particular, by formalizing a well established desynchronization algorithm as a gradient descent method, we establish novel upper bounds on the number of iterations required to reach convergence. Moreover, by using Nesterov's accelerated gradient method, we propose a novel desynchronization primitive that provides for faster convergence to the steady state. Importantly, we propose a novel algorithm that leads to decentralized time-synchronous multichannel TDMA coordination by formulating this task as an optimization problem. Our simulations and experiments on a densely-connected IEEE 802.15.4-based wireless sensor network demonstrate that our scheme provides for faster convergence to the steady state, robustness to hidden nodes, higher network throughput and comparable power dissipation with respect to the recently standardized IEEE 802.15.4e-2012 time-synchronized channel hopping (TSCH) scheme.

Religious Cognition and Moral Cognition
Creators: name: Martin, Alex
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Previous research has shown a connection between religious belief and morality—primarily that religious people both (a) tend to be more prosocial in their behavior, and (b) tend to judge moral infractions in a more categorical or deontological way. The current research looks to further explore the extent to which religious and non-religious people differ in moral judgements of immoral actions, as well as evaluate the evidence for theoretical explanations of these differences. We found that religious people rated all moral infractions as more severe than non-religious people and were less sensitive to the severity of actions. These results conflict with previous theories for differences in moral cognition. Limitations and future directions are discussed.

Borosilicate and Fused-Silica Capillary Microelectrode Electrochemical Comparison and Micromanipulator Adaptor for Fused-Silica Capillary Microelectrodes
Creators: name: Martin, Devon F.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Borosilicate glass is the material predominately used for encasing carbon fiber (CF) microelectrodes for fast-scan cyclic voltammetry (FSCV) experiments. These capillaries insulate unexposed CF from the surrounding environment, while leaving a 150-200 um exposed CF tip in vivo that allows for electrochemical measurements of neurotransmitters. However, borosilicate glass commonly breaks during implantation; this can leave debris in the rat brain and prevent lowering of subsequent electrodes, reducing experimental yield. Additionally, borosilicate glass electrodes often contain cracks at the seal, resulting in undesirable electrochemical characteristics. This can be alleviated with the use of epoxy resin to fill cracks and solidify the seal. Recently, a new design of CF microelectrodes using fused-silica (FS) was announced, which was more flexible and resilient to strain1. This study compares non-epoxied borosilicate, epoxied borosilicate capillary microelectrodes, and FS microelectrodes. The electrochemical characteristics (RMS noise, background amplitude, and background peak locations) between these three designs were compared.
Additionally, the larger diameter of the glass electrodes (600 um compared to 90 um FS) allow them to be used in micromanipulators, which allow for precise control of electrode depth along the dorsal-ventral axis and new electrodes to be used for each experiment. The FS electrodes lack any such device, so an adaptor prototype was developed to match the smaller diameter; the FS electrode construction process was also adjusted to fit the design. These two experiments make FS a more acceptable and useful electrode for in vivo testing.
Smoking Cessation: Is Motivational Interviewing Effective When Guiding Vulnerable Patients to Quit?
Creators: name: Kivett, Joseph
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Introduction: While smoking rates have declined significantly since the first Surgeon General’s report 50 years ago, smoking cessation remains an issue among certain populations. Those suffering from smoking related disorders, such as COPD, lung cancer, ischemic heart disease, and stroke have much to gain from cessation. Individuals with low-income or diagnosed with a substance abuse disorder are disproportionately impacted by cigarette smoking, thus can benefit from cessation efforts as well. Methods: To explore the current approaches of smoking cessation, a literature review was conducted. Once motivational interviewing (MI) was noted as the most oft used counseling strategy, articles implementing MI as the intervention with at-risk populations were screened and 4 articles involving patients with a minimum of 10 year smoking history, biochemically verified as an active smoker , and over 18 were analyzed. Passive observation of a tobacco treatment specialist treating patients in the hospital as well as the clinic was also conducted. Results: The literature revealed statistically significant cessation rates among patients diagnosed with ACS and visiting a pulmonary clinic for respiratory symptoms in addition to clinically significant findings in smokers diagnosed with a substance abuse disorder and patients with low-income. One case, involving a patient with a recent myocardial infarction was selected from the passive observation experience and served as the subject of the case study. Discussion: Many patients have a desire to quit smoking, but only 20 % report receiving assistance from their provider. Findings from the literature and the case study demonstrate the benefit of MI and support its proactive use in healthcare.

Subjects: Fluid-structure interaction and aeroacoustics

description: Aeroacoustic studies of porous cylinder coatings, which reduce the vortex shedding noise of cylinders in uniform flow, have received increased attention. To further understand how porous coatings suppress the vortex shedding tone, a numerical and experimental investigation of porous coated cylinders at a Reynolds number of 1.27×105 is presented herein. Two parameters were varied: (1) the ratio of the porous thickness to the bare cylinder diameter, and (2) the airflow resistivity of the porous media. Numerical simulations were performed using the large-eddy simulation approach with the Smagorinsky sub-grid length-scale model, and the Ffowcs-Williams and Hawkings acoustic analogy was used to predict the acoustic far-field pressure field. A numerical investigation of the internal flow field within the porous layer is presented, which provides a better understanding of the influence of the aforementioned parameters on the development of boundary layers within the porous media and the passive flow and noise control capability. Experiments were performed in an aeroacoustic open-jet wind tunnel to validate the acoustic and external flow field results, which typically showed very good agreement with the numerical results. For porous coatings with low airflow resistivity, the thickness of the porous coating, relative to the inner diameter, has a strong influence on passive flow and noise control. Vortex shedding originates from the inner diameter. Conversely, porous coatings with a higher airflow resistivity are less influenced by their thickness, and vortex shedding originates from the outer diameter (porous surface). The complex coupling of these parameters leads to the conclusion that the optimal selection of the thickness and airflow resistivity is typically dependent on the Reynolds number.

description: Various Li compounds are commonly used at neutron facilities as neutron absorbers. These compounds provide one of the highest ratios of neutron attenuation to $γ$-ray production. Unfortunately, the usage of these compounds can also give rise to fast neutron emission with energies up to almost 16 MeV. Historically, some details in this fast neutron production mechanism can be absent from some modeling packages under some optimization scenarios. In this work, we tested Geant4 to assess the performance of this simulation toolkit for the fast neutron generation mechanism. We compare the results of simulations performed with Geant4 to available measurements. The outcome of our study shows that results of the Geant4 simulations are in good agreement with the available measurements for $^6$Li fast neutron production, and suitable for neutron instrument background evaluation at spallation neutron sources.

description: World knowledge (assertions such as “you can slice an apple”) is useful in a variety of
applications ranging from annotating video segments to generating motion plans for robots. While
people generally already have this kind of knowledge, giving a machine this insight is a challenging
problem. However, with the growth of the internet, there has been an increasing amount of data to
learn from; people post more pictures and write more text every day. From these, one relatively
untapped source of data lies in the domain of cooking, in the form of cooking recipes. As
instructional texts, recipes hold information about states of objects and what changes they undergo
to reach a goal, and thus present an opportunity to learn world knowledge for applications in
automatic illustrations and video annotation. I will present a method to try and extract this
information from these data.
Heteroclinic cycles arising in generic unfoldings of nilpotent singularities

description: In this paper we study the existence of heteroclinic cycles in generic unfoldings of nilpotent singularities. Namely we prove that any nilpotent singularity of codimension four in $\mathbb{R}^4$ unfolds generically a bifurcation hypersurface of bifocal homoclinic orbits, that is, homoclinic orbits to equilibrium points with two pairs of complex eigenvalues. We also prove that any nilpotent singularity of codimension three in $\mathbb{R}^3$ unfolds generically a bifurcation curve of heteroclinic cycles between two saddle-focus equilibrium points with different stability indexes. Under generic assumptions these cycles imply the existence of homoclinic bifurcations. Homoclinic orbits to equilibrium points with complex eigenvalues are the simplest configurations which can explain the existence of complex dynamics as, for instance, strange attractors. The proof of the arising of these dynamics from a singularity is a very useful tool, particularly for applications.

Cation Binding in Nickel Pincer-Crown Ether Systems

Year: 2016

description: The cation binding properties of nickel complexes supported by pincer aza-crown ether aminophosphinite ligands (NCOP) of various sizes are explored. The binding stoichiometry of alkali metal cations interacting with the aza-crown ether is determined to be 1:1 through the method of continuous variations. A modified titration technique is used to gauge the relative interaction strength of alkali metals with the aza-crown ether. For the smaller 15-crown-5 aza-crown ether, the observed order of interaction strength is K+ ≈ Na+ < Li+. Comparisons between two Li+ salts seem to indicate that counter anion effects play a minimal role in cation binding, however, macrocycle size significantly affects cation interaction strength. For the larger 18-crown-6 aza-crown ether, it was observed that Na+ binds stronger than both Li+ and K+. Preliminary investigations into the reversible nature of cation interactions with the pincer aza-crown ether ligand demonstrate easy conversion between the strongly binding tridentate and weakly binding tetradentate regimes.

description: This paper addresses the problem of binaural localization of a single speech source in noisy and reverberant environments. For a given binaural microphone setup, the binaural response corresponding to the direct-path propagation of a single source is a function of the source direction. In practice, this response is contaminated by noise and reverberations. The direct-path relative transfer function (DP-RTF) is defined as the ratio between the direct-path acoustic transfer function of the two channels. We propose a method to estimate the DP-RTF from the noisy and reverberant microphone signals in the short-time Fourier transform domain. First, the convolutive transfer function approximation is adopted to accurately represent the impulse response of the sensors in the STFT domain. Second, the DP-RTF is estimated by using the auto- and cross-power spectral densities at each frequency and over multiple frames. In the presence of stationary noise, an inter-frame spectral subtraction algorithm is proposed, which enables to achieve the estimation of noise-free auto- and cross-power spectral densities. Finally, the estimated DP-RTFs are concatenated across frequencies and used as a feature vector for the localization of speech source. Experiments with both simulated and real data show that the proposed localization method performs well, even under severe adverse acoustic conditions, and outperforms state-of-the-art localization methods under most of the acoustic conditions.

description: Nutrient deprivation (starvation) induced by fasting and hypercaloric regimens are stress factors that can influence cell and tissue homeostasis in mammals. One of the key cellular responses to changes in nutrient availability is the cell survival pathway, autophagy. While there has been much research into the protein networks regulating autophagy, less is known about the gene expression networks involved in this fundamental process. Here, we applied a network algorithm designed to analyze omics datasets, to identify sub-networks that are enriched for induced genes in response to starvation. This enabled us to identify two prominent active modules composed of key stress-induced transcription factors, including members of the Jun, Fos, and ATF families, and the other comprising autophagosome sub-network genes, including ULK1. The results were validated in the brain, liver, and muscle of fasting mice. Moreover, differential expression analysis of autophagy genes in the brain, liver, and muscle of high-fat diet-exposed mice, showed significant suppression of GABARAPL1 in the liver. Finally, our data provide a resource that may facilitate the future identification of regulators of autophagy.

ITGA2+ Endoneurial Cells and Extracellular Periostin are Upregulated in Chronic Inflammatory Demyelinating Polyneuropathy
Creators: name: Kimpston, Caellaigh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) is an autoimmune disorder of the peripheral nervous system characterized by weakness, imbalance, sensory loss and pain. Previously, our lab showed that a strain of NOD mice with a dominant G228W mutation (NOD.AireGW/+ mice) develops spontaneous autoimmune peripheral neuropathy and is a model for CIDP. In the peripheral nerves of neuropathic mice, our lab observed an increase in a population of cells that expressed ITGA2 (a classical marker for NK T cells) and expressed 60-fold higher RNA transcripts of extracellular periostin compared to dendritic cells and T cells. We aimed to determine what types of cells are expressing ITGA2 and to determine whether periostin expression is upregulated in the sciatic nerves of neuropathic mice. Using immunofluorescence staining of ITGA2 and CD3 (a classical marker for T cells) in sciatic nerve sections from neuropathic mice, we found that the CD3+ cells did not co-localize with ITGA2 staining suggesting that the ITGA2+ cells are not infiltrating T cells or NK T cells. Additionally, we found that the ITGA2+ cells were enriched in the neuropathic mice compared to wild type mice. Using qRT-PCR, western blot, and immunofluorescence for periostin, we found that periostin was enriched at the mRNA and protein level in neuropathic mice as compared to the wild-type mice. These findings suggest a possible pathogenic or maintenance role of ITGA2+ cells and periostin in CIDP. Consequently, these findings may have important implications in the further study of the pathogenesis of CIDP and help guide more targeted therapeutics for CIDP in the future.

AGPAT Enzyme Activity and Localization in GPAT3 and GPAT4 Knockout Mice
Creators: name: Veliko, Liliya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Triacylglycerol (TAG) is a fat that serves as a vital energy source in eukaryotes. TAG is
synthesized de novo in the liver and fat cells through a pathway that is initiated by the enzyme
glycerol-3-phosphate acyltransferase (GPAT) and next catalyzed by acylglycerolphosphate
acyltransferase (AGPAT). It was hypothesized the deletion of GPAT would result in decreased
activity in the TAG synthesis pathway and therefore decreased AGPAT activity. To investigate
this idea, the activity of AGPAT was assayed in tissue homogenates from liver and adipose of
mice lacking GPAT3 or GPAT4, the main GPAT isoforms. Contrary to the hypothesis, AGPAT
activity was elevated in GPAT3-deficient and GPAT4-deficient liver samples and adipose
samples compared to those prepared from wild type mice. This result suggests the activity of
the TAG synthesis pathway increases to compensate for the absence of the rate limiting
enzyme, GPAT. In addition to AGPAT’s responsiveness to GPAT, the sub-cellular localization
of AGPAT was also explored. AGPAT was known to localize to the ER membrane, but it is
hypothesized that the ER shares membranes with lipid droplets, the organelles that store TAG.
Thus, we predicted that AGPAT activity would be detectable in isolated lipid droplets. AGPAT
activity was measured in lipid droplet and microsomal fractions of murine wild type, GPAT3-
deficient and GPAT4-deficient livers. AGPAT activity was indeed detected in the lipid droplet
fraction, supporting our hypothesis that the ER membranes are contiguous with lipid droplets.
AGPAT activity was higher in lipid droplet and microsomal fractions in GPAT3-deficient tissues
compared to wild type mice, consistent with our results above and suggesting a general
cellular response to the absence of a major GPAT isoform. Understanding the functions and
interactions of the enzymes along the TAG synthesis pathway can provide insights that will

description: We introduce a generalized $d$-dimensional Fermi-Pasta-Ulam (FPU) model in presence of long-range interactions, and perform a first-principle study of its chaos for $d=1,2,3$ through large-scale numerical simulations. The nonlinear interaction is assumed to decay algebraically as $d_{ij}^{-α}$ ($α\ge 0$), $\{d_{ij}\}$ being the distances between $N$ oscillator sites. Starting from random initial conditions we compute the maximal Lyapunov exponent $λ_{max}$ as a function of $N$. Our $N>>1$ results strongly indicate that $λ_{max}$ remains constant and positive for $α/d>1$ (implying strong chaos, mixing and ergodicity), and that it vanishes like $N^{-κ}$ for $0 \le α/d < 1$ (thus approaching weak chaos and opening the possibility of breakdown of ergodicity). The suitably rescaled exponent $κ$ exhibits universal scaling, namely that $(d+2) κ$ depends only on $α/d$ and, when $α/d$ increases from zero to unity, it monotonically decreases from unity to zero, remaining so for all $α/d >1$. The value $α/d=1$ can therefore be seen as a critical point separating the ergodic regime from the anomalous one, $κ$ playing a role analogous to that of an order parameter. This scaling law is consistent with Boltzmann-Gibbs statistics for $α/d > 1$, and possibly with $q$-statistics for $0 \le α/d < 1$.

description: We report on the first atom interferometer based on Bragg diffraction in a fountain of alkaline-earth atoms, namely $^{88}$Sr. We demonstrate large momentum transfer to the atoms up to eight photon recoils and the use of the interferometer as a gravimeter with a sensitivity $δg/g=4\times 10^{-8}$. Thanks to the special characteristics of strontium atoms for precision measurements, this result opens a new way for experiments in fundamental and applied physics.

One Man's Disgust is Another Man's Fear: Individual Differences in Emotion Experiences
Creators: name: Pradhan, Phoebe
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The same stimulus may elicit different affective responses across individuals and contexts. According to the psychological constructionist perspective of emotion, individual differences in emotion experiences arise in part from differences in emotion conceptual knowledge and emotion granularity. The present study examined how individual differences in emotion conceptual knowledge complexity and emotion granularity influence perceivers’ ability to distinguish between fear and disgust. We hypothesized that greater conceptual knowledge complexity and greater emotion granularity would be associated with more emotion-specific appraisals of fear and disgust stimuli on an appraisal task. To investigate our hypothesis, 96 undergraduate students at The University of North Carolina at Chapel Hill were recruited for the study. Overall, our hypothesis was not supported insofar that individual differences in conceptual knowledge complexity and emotion granularity did not predict the degree of emotion-specific appraisals of fear and disgust stimuli.
Joint Reasoning for Camera and 3D Human Pose Estimation
Creators: name: Xu, Yan
Publisher: name: Carnegie Mellon University
Year: 2023
Subjects: Applied Computer Science

description: Estimating the 6-DoF camera pose and the 3D human pose lies at the core of many computer vision tasks, such as virtual reality, augmented reality, and human-robot interaction. Existing efforts either rely on large amounts of 3D training data for each new scene or require strong prior knowledge, e.g., known camera poses, only available in laboratory environments. Despite the improvements in the numbers on a few public datasets, the gap between laboratory research and real-world applications remains. The objective of this thesis is to develop camera and human pose estimation methods that can bridge this gap. This thesis includes two parts. The first part focuses on camera pose estimation using human information. We first introduce a single-view camera pose estimation method that uses a lightweight network trained only on synthetic 2D human trajectory data to directly regress the camera pose at test using real human trajectories. After that, we present a wide-baseline multi-view camera pose estimation method that treats humans as key points and uses a re-ID network pre-trained on public datasets to embed human features for solving cross-view matching. We show that both methods do not require 3D data collection and annotation and generalize to new scenarios without extra effort. The second part of this thesis concentrates on multi-view multi-person 3D human pose estimation targeting the challenging setting where the camera poses are unknown. We present a method that follows the detection-matching-reconstruction process and treats the cross-view matching as a clustering problem with the number of humans and cameras as constraints. Compared with existing methods, ours is one of the first that does not require camera poses, 3D data collection, or model training for each specific dataset. Next, we further improve the method by introducing a multi-step clustering mechanism and leveraging short-term single-view tracking to boost cross-view matching performance. Our method shows excellent generalization ability across various in-the-wild settings.
Exact thermal density functional theory for a model system: Correlation components and accuracy of the zero-temperature exchange-correlation approximation

description: Thermal density functional theory calculations often use the Mermin-Kohn-Sham scheme, but employ ground-state approximations to the exchange-correlation (XC) free energy. In the simplest solvable nontrivial model, an asymmetric Hubbard dimer, we calculate the exact many-body energies and the exact Mermin-Kohn-Sham functionals for this system and extract the exact XC free energy. For moderate temperatures and weak correlation, we find this approximation to be excellent. We extract various exact free-energy correlation components and the exact adiabatic connection formula.

description: The management of road traffic has undergone a radical change as a result of the quick development of artificial intelligence (AI). The movement of people, things, cars, and cargo at various points on the transportation network may now be predicted and controlled by AI with remarkable accuracy. AI is making it feasible to prevent accidents by optimising flows at crossings and enhancing safety during times when roads are closed due to construction or other activities, in addition to offering citizens better service than ever before. Furthermore, efficient mass transit, like ride-sharing services, has been made possible by AI's capacity to process and analyse enormous volumes of data. Then how is road traffic management being revolutionised by AI? The study uses secondary data for analysis of the present study. This study is limited to automated vehicles including Taxis, Buses, Delivery vans or drones Trains, Commercial aircraft etc. .
Novel Small Modular Reactors and Their Application Feasibility in Alaskan Cities

description: Nuclear power, using the energy from nuclear reactions to generate heat and electricity, first made its appearance in the 1940’s, and has been emerging as a major player in the world’s energy market since then. Currently, there are over 440 commercial nuclear power reactors operable in 31 countries and providing over 11% of the world’s electricity (1). Nuclear energy has its popularity, as it has been thought as a continuous and reliable baseload power with no carbon dioxide or other greenhouse gas emissions, in another word, a “clean energy.” It is also the most controversial energy source, with many arguments and concerns about its safety and social impacts. Current major nuclear power generating nations in the world include the United States, France, Russia, China and South Korea. Even though nuclear energy has been widely deployed, the forwardness of technology never ceased; innovative nuclear technologies are under development in many countries, some in cooperation with other nations. One of the newer technologies is in the development of small modular reactors (SMRs). Small Modular Reactors defined by the International Atomic Energy Agency (IAEA) as reactors with a power rating lower than 300 MWe factory-built elements or modules designed for serial construction (2). It is a term that has not been brought up for a long time, though it is becoming a spotlight in the field of nuclear energy with soaring public attention in recent decades. SMR, for the most part, is an unmatured technology, other than on naval ships (2), that is still under development. This thesis will assess their projected efficacy in the 2030 timeframe (technical, environmental, social and economic). Further, their conceptual siting and use in two Alaskan cities, Fairbanks and Juneau, will be evaluated. These evaluations will be based on the anticipated best available (or soon to be available) fast SMR technology in 2030.
A reciprocal theorem for boundary-driven channel flows

description: In a variety of physical situations, a bulk viscous flow is induced by a distribution of surface velocities, for example in diffusiophoresis (as a result of chemical gradients) and above carpets of cilia (as a result of biological activity). When such boundary-driven flows are used to pump fluids, the primary quantity of interest is the induced flow rate. In this letter we propose a method, based on the reciprocal theorem of Stokes flows, to compute the net flow rate for arbitrary flow distribution and periodic pump geometry using solely stress information from a dual Poiseuille-like problem. After deriving the general result we apply it to straight channels of triangular, elliptic and rectangular geometries and quantify the relationship between bulk motion and surface forcing.

Aquatic Invertebrates of an Andean Cloud Forest: Community Structure and Environmental Gradients
Creators: name: Bettcher, Morgan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The purpose of this study is to examine the structure of aquatic communities of tropical headwater streams of the Andean cloud forest and determine abiotic environmental factors that may be significant to the biological integrity. This will be accomplished by examining the distribution of globally important benthic invertebrate taxa: especially the orders Ephemeroptera, Plecoptera, and Trichoptera (EPT). The EPT orders are some of the most abundant and important members of stream networks, and in South America as well as throughout much of the world they make up the primary components of many water quality monitoring efforts (Acosta et al. 2009; Dominguez and Fernández 2009). In order to guide future conservation decisions, we need to enhance our understanding of change in the cloud forest, and aquatic insect communities will help us achieve our goals.
