Effect Of Heat Treatment On The Mechanical Properties In Natural Bamboo, Austin Levy, Mackenzie Kirkpatrick

Materials Engineering

Previous studies have shown that heat treatments have the ability to improve mechanical strength and stiffness in hardwood species. Compared to structural hardwoods, bamboo is a more sustainable and globally viable renewable resource. Therefore, Bambusoides vivax (timber bamboo) culms were fabricated into flat, rectangular cross-section samples with varying cellulose content to be heat treated and tested for mechanical properties. All samples were heat treated (HT) twice. The first HT was a normalization of all samples at 103 +/- 3 °C. The second HT was performed at various times and temperatures ranging from 130°C to 170°C for 0.5 to 3 hours. …

Crossed Mcmurry Coupling Reactions For Porphycenic Macrocycles: Non-Statistical Selectivity And Rationalisation, Thomas Y. Cowie, Lorna Kennedy, Justyna M. Zurek, Martin J. Paterson, Magnus Bebbington

Department of Chemistry and Biochemistry Faculty Scholarship and Creative Works

Crossed McMurry reactions of bifuran- or bithiophenedicarbaldehydes with bipyrroledicarbaldehydes have been studied for the first time. Only those porphycenic macrocycles derived from homocoupled McMurry products were formed. The results are explained by using both density functional theory and electron propagator computations to model the electron affinity of the dialdehyde starting materials. It was predicted that bifuran\bithiophene cross-coupling would indeed occur, and this was demonstrated by the first synthesis of a novel dioxa,dithio hetero-porphycenoid annulene. This approach will allow the prior identification of viable substrates for related crossed McMurry reactions. In the first study of its type, experimental and computational studies …

The Battle Over Plant Genetic Resources: Interpreting The International Treaty For Plant Genetic Resources, Katie Bass

Chicago Journal of International Law

International law is full of holes, inconsistencies, and ambiguities because of the number of overlapping treaties, agreements, and actors at play. One such ambiguity can be found in the overlapping system of treaties that govern plant genetic resources. Specifically, the International Treaty for Plant Genetic Resources (ITPGR) provides for international sharing of plant genetic resources to protect the biodiversity necessary for human food production. However, the ITPGR is a non-binding treaty that is challenging to implement in light of international treaties that allow plant genetic resources to be claimed as intellectual property rights. ITPGR is not as a matter of …

Influence Of Changes In Political Barriers And Of Geographic Distance On Kinship Inferred From Surnames And Migration Data In Olivenza (Spain) And Surrounding Portuguese Areas, J. Román-Busto

Human Biology Open Access Pre-Prints

The existing relationship between human populations is a function of their migratory and genetic exchange which will be inversely proportional to the distance separating them. The effect of geographic distance on population structure may be estimated by means of isonymic methods which use information on the surnames present in a territory as an approximation to the distribution of allele frequencies. The objective of this study is to analyse whether the modification in 1801 of the political border in an area surrounding the town of Olivenza, which experienced a change of sovereignty from Portugal to Spain, has had noticeable influence on …

Object Permanence In The Dwarf Goat (Capra Aegagrus Hircus): Perseveration Errors And The Tracking Of Complex Movements Of Hidden Objects, Christian Nawroth, Eberhard Von Borell, Jan Langbein

Memory Collection

Object permanence is the notion that objects continue to exist even when they are out of an observer’s sight. In mammals, the highest stage of object permanence (Stage 6) has been observed only in primates, whereas other species have shown difficulty in following once-hidden objects, particularly when complex movements are involved. We conducted four experiments to examine the ability of dwarf goats to mentally represent once-hidden objects. In Experiment 1, we investigated whether dwarf goats are prone to commit the A-not-B or perseveration error which is commonly used as a measure for self-control. Subjects here continue to search for an …

Focusing On The Six Major Themes In The Global Perspective Of Andragogy: A June 2015 Update, John Henschke

Adult Education Faculty Works

Andragogy has received various mixed reviews in the past. Some have analyzed it from a positive perspective. Others have analyzed it from a negative perspective, still others have viewed it from a neutral or passive point of view while some have ignored it altogether. Most of the discussions have limited their observations to how Malcolm S. Knowles addressed andragogy. There has been an inadequate investigation of the foundation and background of andragogy from a world perspective. This research presents more than 450 major works published in English from national and international sources on andragogy that may help provide a clear …

Kcnj10 (Kir4.1) Is Expressed In The Basolateral Membrane Of The Cortical Thick Ascending Limb, Chengbiao Zhang, Lijun Wang, Xiao-Tong Su, Dao-Hong Lin, Wen-Hui Wang

NYMC Faculty Publications

The aim of the present study is to examine the role of Kcnj10 (Kir.4.1) in contributing to the basolateral K conductance in the cortical thick ascending limb (cTAL) using Kcnj10(+/+) wild-type (WT) and Kcnj10(-/-) knockout (KO) mice. The patch-clamp experiments detected a 40- and an 80-pS K channel in the basolateral membrane of the cTAL. Moreover, the probability of finding the 40-pS K was significantly higher in the late part of the cTAL close to the distal convoluted tubule than those in the initial part. Immunostaining showed that Kcnj10 staining was detected in the basolateral membrane of the cTAL but …

Discours Sur L’Environnement Et Stratégies Empathiques De L’Hégémonie Dans Les Écritures Francophones D’Afrique Noire, Jean-Blaise Samou

Présence Francophone: Revue internationale de langue et de littérature

It is a known that discourse developed on Africa in the European imagination between the late nineteenth and the first half of the twentieth century had largely contributed to the implementation of colonial ideology. Today, African writings recover and rework those discourses, highlighting the language strategies by which the construction of a tropical otherness, territorial dispossession and colonial domination in Africa were part of a pragmatic discourse. The analysis of those discourses in some novels and movies from French-speaking Black Africa not only reveals the environmental issues that underlay the European colonial adventure in Africa, but also the interest for …

Harvest Strategy Policy And Operational Guidelines For The Aquatic Resources Of Western Australia, Western Australia. Dept. Of Fisheries

Fisheries Management Papers

Harvest strategies establish the decision rules that determine the appropriate harvest levels for all sectors to meet the ecological, economic and social objectives established for a resource. The development and implementation of formal harvest strategies is considered sound practice in contemporary fisheries management. A number of recent legislative (new Aquatic Resources Management Act, ARMA) and policy (Marine Stewardship Council, MSC) initiatives require the development of formal harvest strategies for the key aquatic resources in Western Australia (WA).

Anticipatory Socialization Of Pregnant Women: Learning Fetal Sex And Gendered Interactions, Medora W. Barnes

Sociology

Although doctors still frequently call out “It’s a girl!” when a baby girl is born, the majority of mothers now use ultrasound to find out the sex months earlier. This study examines how women who learn the sex of their fetus before birth are engaging in gendered verbal interactions throughout pregnancy. These include types of conversations, usage of gendered pronouns, and calling the unborn baby by a given name. These changes in behaviors by pregnant woman once fetal sex is known can be seen as a form of anticipatory socialization, as they begin to practice the behaviors and values associated …

Combinatorial Effects Of Fatty Acid Elongase Enzymes On Nervonic Acid Production In Camelina Sativa, Dongxin Huai, Yuanyuan Zhang, Chunyu Zhang, Edgar B. Cahoon, Yongming Zhou

Center for Plant Science Innovation: Faculty Publications

Very long chain fatty acids (VLCFAs) with chain lengths of 20 carbons and longer provide feedstocks for various applications; therefore, improvement of VLCFA contents in seeds has become an important goal for oilseed enhancement. VLCFA biosynthesis is controlled by a multi-enzyme protein complex referred to as fatty acid elongase, which is composed of β-ketoacyl-CoA synthase (KCS), β-ketoacyl-CoA reductase (KCR), β-hydroxyacyl-CoA dehydratase (HCD) and enoyl reductase (ECR). KCS has been identified as the ratelimiting enzyme, but little is known about the involvement of other three enzymes in VLCFA production. Here, the combinatorial effects of fatty acid elongase enzymes on VLCFA production …

Evolution And Otitis Media: A Review, And A Model To Explain High Prevalence In Indigenous Populations, Mahmood F. Bhutta

Human Biology Open Access Pre-Prints

Inflammation of the middle ear (otitis media) comprises a group of disorders that are highly prevalent in childhood, and indeed are amongst the most common disorders of childhood. Otitis media is also heritable, and has effects on fecundity. This means that otitis media is subject to evolution, yet the evolutionary selection forces that may determine susceptibility to otitis media have never been adequately explored.

Here I undertake a critical analysis of evolutionary forces that may determine susceptibility to middle ear inflammation. These forces include those determining function of the middle ear, those affecting host immunity, and those affecting colonization by, …

Significant Up-Regulation Of Mir-17 In An Alzheimer’S Disease Mouse Model, Matthew Dalton, Amanda Hazy, Gary D. Isaacs

Other Undergraduate Scholarship

Previous work by our group has demonstrated a correlation between AD pathology and changes in epigenetic markers, including cytosine methylation of gene promoter regions. Several genes determined to have AD-related changes in methylation code for miRNA, which is known to regulate gene expression at a post-transcriptional level. Research suggests that miRNA play a key role in AD development by alteration of gene products and transcription factors, particularly in that of amyloid-ß (Aß) production and apoptosis of postmitotic neurons. This analysis shows a significant up-regulation of demonstrated epigenetically modified miR-17 in the hippocampi of transgenic AD mice when compared to that …

Micro-Motion Controller, Kapoor Karan, Chu Cameron, Adem Sandeep

Bioengineering Senior Theses

Micro-motions in surgical applications are small motions in the range of a few millimeters and are common in ophthalmic surgery, neurosurgery, and other surgeries which require precise manipulation over short distances. Robotic surgery is replacing traditional open surgery at a rapid pace due to the obvious health benefits, however, most of the robotic surgical tools use robotic motion controllers that are designed to work over a large portion of the human body, thus involving motion of the entire human arm at shoulder joint. This requirement to move a large inertial mass results in undesirable, unwanted, and imprecise motion. This senior …

Lipid-Coated Gold Nanoparticle As A Biosensor For Lipid-Protein Interactions, Yuheng Cai

Electronic Theses and Dissertations

Gold nanoparticles have been intensively studied for their unique optical features. Due to surface plasmon resonance phenomenon, gold nanoparticles can respond to the refractive index change of the environment near the particles. This phenomenon gives gold nanoparticles the potential to become biosensors that detect the biological interactions at or near the particles. In this work, gold nanospheres were coated with phosphatidylcholine as the substrate for lipoxygenase. It is demonstrated, in our work, that lipid coated gold nanospheres can be used to detect the activity of lipoxygenase and provide more information of this reaction than common assays, like conjugated diene assay …

On The Stability Of A Three Species Syn-Eco-System With Mortality Rate For The Third Species, B. H. Prasad

Applications and Applied Mathematics: An International Journal (AAM)

The system comprises of a commensal (S₁) common to two hosts S₂ and S₃ with mortality rate for the host (S₃). Here all the three species posses limited resources. The model equations constitute a set of three first order non-linear simultaneous coupled differential equations. Criteria for the asymptotic stability of all the eight equilibrium states are established. Trajectories of the perturbations over the equilibrium states are illustrated. Further the global stability of the system is established with the aid of suitably constructed Liapunov’s function and the numerical solutions for the growth rate equations are …

The Divergent Effects Of Fear And Disgust On Inhibitory Control: An Erp Study., Mengsi Xu, Zhiai Li, Cody Ding, Junhua Zhang, Lingxia Fan, Liuting Diao, Dong Yang

Education Sciences and Professional Programs Faculty Works

Negative emotional stimuli have been shown to attract attention and impair executive control. However, two different types of unpleasant stimuli, fearful and disgusting, are often inappropriately treated as a single category in the literature on inhibitory control. Therefore, the present study aimed to investigate the divergent effects of fearful and disgusting distracters on inhibitory control (both conscious and unconscious inhibition). Specifically, participants were engaged in a masked Go/No-Go task superimposed on fearful, disgusting, or neutral emotional contexts, while event-related potentials were measured concurrently. The results showed that for both conscious and unconscious conditions, disgusting stimuli elicited a larger P2 than …

Penile Microbiota And Female Partner Bacterial Vaginosis In Rakai, Uganda, Cindy M. Liu, Bruce A. Hungate, Aaron A.R. Tobian, Jacques Ravel, Lance B. Price, +8 Additional Authors

Environmental and Occupational Health Faculty Publications

Bacterial vaginosis (BV) is a common vaginal bacterial imbalance associated with risk for HIV and poor gynecologic and obstetric outcomes. Male circumcision reduces BV-associated bacteria on the penis and decreases BV in female partners, but the link between penile microbiota and female partner BV is not well understood. We tested the hypothesis that having a female partner with BV increases BV-associated bacteria in uncircumcised men. We characterized penile microbiota composition and density (i.e., the quantity of bacteria per swab) by broad-coverage 16S rRNA gene-based sequencing and quantitative PCR (qPCR) in 165 uncircumcised men from Rakai, Uganda. Associations between penile community …
