Genetics And Molecular Dynamics Of L,L-Diaminopimelate Aminotransferase (Dapl): An Enzyme Involved In Lysine And Peptidoglycan Biosynthesis, Lily E.J. Adams

Theses

The marked increase of bacteria that are resistant to clinically relevant antibiotics in recent years has sparked a push in the development and discovery of novel antibiotics. Complementary to this, the identification of novel antibiotic targets is also of great interest. The lysine biosynthesis pathway is an ideal candidate for these efforts because its product is an essential amino acid. Lysine cannot be synthesized by humans and thus poses minimal risk of side effects if synthesis is targeted. The penultimate product in the lysine biosynthesis pathway, meso-DAP, is also a key component of the gram-negative bacterial cell wall peptidoglycan layer. …

Transcriptome-Wide Analysis Of Vsv Strains With Varying Ability To Block Nf-Κb, Thomas M. Russell

Theses

Vesicular stomatitis virus (VSV) is a negative sense, single-stranded RNA (ssRNA) virus that is currently studied for its uses as a vaccine viral vector and its potential in oncolytic therapy. The M protein of VSV is the active participant in the virus’s abrogation of the host innate immune response. This activity is thought to be due to the M protein’s ability to downregulate overall host transcription by blocking nuclear transport. A VSV mutant containing a D52G mutation in the M protein (22-20) has been shown to block nuclear transport while being defective as a suppressor of NF-κB activation. It is …

Theses

As global environmental concerns increase, industries continue to respond prominently to meeting sustainable practice standards through technological innovations and new business models. However, current sustainability measurement tools, including Life Cycle Assessment (LCA), do not provide practitioners with sufficiently standardized methodology, which leads to uncertainty and limited comparability of results. This research develops a systematic Object-Oriented LCA method to define and quantify the consumed life of a product system during the use scenario under analysis. In this method, the Cumulative Damage Function (CDF) quantifies the consumed life of a product by using inputs of total efficiency or damage, scaling parameters and …

Stimulating Interethnic Contact In Kosovo: The Role Of Social Identity Complexity And Distinctiveness Threat, Edona Maloku, Belle Derks, Colette Van Laar, Naomi Ellemers

Articles

The positive effects of intergroup contact on prejudice reduction have been widely validated by now. However, the potential of contact for intergroup relations is only available when there is readiness to have contact with outgroup members to begin with. In two correlational studies with the main ethnic groups in postconflict Kosovo, Albanian majority (Study 1, N = 221) and Serb minority (Study 2, N = 110), we examine how social identity complexity mechanism and distinctiveness threat contribute to predicting more readiness to have contact with outgroup members. As the establishment of a new national identity unfolds, we show that while …

Sense - Recommendation System Based On Affective Interpretations Of Social Media Posts: A Proposed User Interface Design, Zheng Zhang

Theses

It is now easier and cheaper for people to get involved in technology, and most people are obtaining or receiving tons of information nowadays, such as recommendations. Different recommendations are filled with our devices like smartphones, tablets or even wearable devices. However, most searches and recommendation systems fail to take into consideration the emotional context related to a user’s input and action, and as a consequence, people can hardly receive personalized, emotion-related, user-based recommendations. Though people are given various choices about lives based on searches and saved data, those recommendations can hardly improve the stress and difficulties of accomplishing daily …

Modeling And Extraction Of Transport Parameters To Simulate Drug Delivery In The Murine Cochlea, Kevin Wilson

Theses

The usage of 1D and 3D models to simulate drug transport through the inner ear is a prominent method in cochlear fluid pharmacokinetics. However, the data used to create these models, is often based on invasive sampling methods that limit the spatial resolution given the size of the cochlear compartments within which solute can be measured. In this work by leveraging 3-D registered micro-Computed Tomography (μCT) scans of the murine cochlea that have been taken as iodinated contrast agent is delivered to it, we extract transport parameters and simulate a forward 1D model that allows variable and pulsatile delivery profiles …

Existing systems for reporting cellular outages do not provide adequate geographical granularity and do not provide a real-time view of the state of the communication network. This work presents a system for real-time measurement of both coverage and quality of service via crowdsourced measurements from consumer and first responder phones. Baseline coverage and quality of service data is collected prior to a major disaster. During a major disaster, real-time data is compared to baseline to identify areas of congestion or outages. Such information can be used by incident commanders to more effectively deploy resources during major disasters. Furthermore, such system …

Arrows In Biology: Lack Of Clarity And Consistency Points To Confusion For Learners, Leslie Kate Wright, Jordan J. Cardenas, Phyllis Liang, Dina L. Newman

Articles

In this article, we begin to unpack the phenomenon of representational competence by ex¬ploring how arrow symbols are used in introductory biology textbook figures. Out of 1214 figures in an introductory biology textbook, 632 (52%) of them contained arrows that were used to represent many different concepts or processes. Analysis of these figures revealed little correlation between arrow style and meaning. A more focused study of 86 figures containing 230 arrows from a second textbook showed the same pattern of inconsistency. Interviews with undergraduates confirmed that arrows in selected textbook figures were confusing and did not readily convey the information …
