BACILLALES INFLUENCE QUALITY AND SAFETY OF DAIRY PRODUCTS
(2017-12-30)Bacillales, an order of Gram-positive bacteria, are commonly isolated from dairy foods and at various points along the dairy value chain. Three families of Bacillales are analyzed in this work: (i) Listeriaceae (represented ... -
BACILLUS SUBTILIS CELL ENVELOPE STRESS RESPONSES INDUCED BY ANTIBIOTICS AND GENETIC PERTURBATIONS OF MEMBRANE COMPOSITION
(2008-07-28)Bacteria thrive in many different habitats, and therefore will encounter a multitude of environmental stresses. Survival requires the development of sophisticated response mechanisms that can identify potential threats and ... -
Bacillus Subtilis Extracytoplasmic Function Sigma Factors Control Antibiotic Production And Resistance
(2012-05-27)Bacillus subtilis, the model organism for Gram-positive bacteria, expresses seven extracytoplasmic function (ECF) [sigma] factors (called [sigma]M, [sigma]W, [sigma]X, [sigma]Y, [sigma]V, [sigma]Z and [sigma]YlaC). [sigma]M, ... -
BACK "HOME": THREE ESSAYS ON MEXICAN RETURN MIGRANTS AND MEXICAN-AMERICAN CHILDREN'S ASSIMILATION IN MEXICO.
(2019-08-30)This dissertation studies how transnationalism, understood as the process of building cross-national relationship, identities, and practices (Levitt and Schiller 2004), affects the children of migrants—those who were born ... -
Back Side Charge Trapping Nano-Scale Silicon Non-Volatile Memories
(2005-07-22)A new alternative device structure for scalable silicon non-volatile memories was investigated. The difficulties in scaling current devices arise from the non-scalability of the gate stack formed by the tunneling oxide, ... -
Back to Black: Racial Reclassification and Political Identity Formation in Brazil
(2019-08-30)This dissertation leverages a phenomenon of racial reclassification in Brazil to shed new light on the processes of identity politicization. Conventional wisdom tells us that the history of race mixture, fluid racial ... -
Background Influences: Psychological Processes That Shape Perception, Emotion, And Morals
(2013-05-26)In this three chapter dissertation, I address the epistemic significance of psychological processes that shape emotion, perception, and moral judgment. In Chapter 1, I illustrate ways in which perceptual and emotional ... -
BACTERIAL COMPOSITION OF HUMAN MILK PUMPED AND STORED IN REAL-LIFE CONDITIONS: A RANDOMIZED, CONTROLLED INVESTIGATION
(2019-12)Women use a variety of practices to handle and store their pumped breast milk. Little is known about how these practices influence milk’s bacterial composition. We conducted an in-home randomized, controlled, crossover ... -
Bacterial Ecology Of High Temperature Short Time Pasteurized Fluid Milk
(2009-08-19)The Grade "A" Pasteurized Milk Ordinance (PMO) specifies minimum processing conditions of 72 degrees C for at least 15 s for high-temperature, short-time (HTST) pasteurized milk products. Currently, many US milk processing ... -
Balancing selection for aflatoxin production in Aspergillus flavus may be maintained by competition with insects and microbes
(2018-08-30)The role of microbial secondary metabolites in the ecology of the organisms that produce them remains poorly understood. Variation in aflatoxin production by Aspergillus flavus is maintained by balancing selection, but the ... -
Balancing Splicing Speed with Fidelity: Role of a Structural Toggle in the RNaseH Domain of Prp8
(2018-08-30)The molecular mechanisms by which the spliceosome achieves high fidelity during pre-mRNA splicing while simultaneously maintaining a high rate remain poorly understood. Here, I show a role for a core spliceosomal factor, ... -
Balancing The Costs Of Inbreeding In Cooperative Crows
(2009-10-13)Because the cooperatively breeding American crow (Corvus brachrhynchos) exhibits natal philopatry of both sexes, related adults of the opposite sex interact, increasing the probability of matings between kin. Cooperative ... -
Ballistic Electron Transport in Aluminum Oxide
(2004-05-11)Aluminum oxide (alumina) is becoming an increasingly important material in high performance electronics. It is the insulator in magnetic tunnel junctions used for MRAM and may allow for the fabrication of solid state ... -
Ballistic Transport and Large Spin Hall Effect in a Silicene MOSFET
(2017-01-30)In an effort to surmount the issues that arise when attempting to scale transistors down to the low nanometer regime, the use of two-dimensional materials in transistors is regarded as a possible solution. One such material, ... -
Banks And The Bonding Hypothesis
(2012-05-27)Previous research has indicated the effect that regulatory jurisdictions have on firm corporate governance. Firms that need to finance investments can reduce their cost of capital by adopting stronger regulation by ... -
Barriers To Children'S Cognitive Achievements: Evidence From Senegal
(2011-01-31)Children's poor learning represents a major constraint to escape from poverty and develop a productive work force in much of the developing world. In this thesis, I focus on one particular barrier to children's learning ... -
BARRIERS TO GENE EXCHANGE IN A FIELD CRICKET HYBRID ZONE
(2008-05-19)Understanding how speciation influences patterns of molecular evolution and how molecular changes drive speciation are central questions in evolutionary biology. In this dissertation I address questions of behavioral ... -
Barriers to Translocation: Stability, Kinetics, and Acid Denaturation of AvrPto
(2008-08-01)In order to infect their hosts, many gram-negative bacteria translocate agents of infection, called effector proteins, through the Type III Secretion System (TTSS) into the host cytoplasm. This process is thought to require ... -
Barriers To Weight-Related Health Behaviors: A Qualitative Comparison Of The Socio-Ecological Conditions Between Pregnant And Postpartum Low-Income Women
(2013-08-19)The association between socio-ecological factors and poor health outcomes for the low-income women and their children has been the focus of disparities research for several decades. Comparative qualitative studies have ... -
Basin and Paleoclimate Evolution of the Pampa del Tamarugal Forearc Valley, Atacama Desert, Northern Chile
(2008-04-04)This work details the Neogene to Recent evolution of the Pampa del Tamarugal (20?30? - 21?45?S), a northward-trending forearc basin located between the Coastal Cordillera to the west and the Precordillera to the east in ...
