Active Targeting Of Estrogen Receptor (Er)-Positive Breast Cancer Cells Using Nanotechnology, Molly White

Theses and Dissertations

The American Cancer Society has predicted an estimated 281,550 new invasive breast cancer cases for 2021. Chemotherapy is one of the main options available to treat this disease, but it can result in drug resistance and harmful side effects, as traditional methods do not directly target the cancer cells. To address this issue, nano formulations have been widely researched for targeted delivery of anticancer drugs. The primary objective of this project was to develop a novel nanodrug, rapamycin-loaded gold nanorods functionalized with polyethylene glycol and epithelial cell adhesion molecule (EpCAM), to selectively target breast cancer cells. The work involved characterizing …

Replication Data For: Characterization Of Grain-Size Distribution, Thermal Conductivity, And Gas Diffusivity In Variably Saturated Binary Sand Mixtures, C. T.K.K. Deepagoda, Kathleen Smits

Earth & Environmental Sciences Datasets - Archive

Characterization of differently textured porous materials, as well as different volumetric porous media mixtures, in relation to mass and heat transport is vital for many engineering and research applications. Functional relations describing physical (e.g., grain-size distribution, total porosity), thermal, and gas diffusion properties of porous media and mixtures are necessary to optimize the design of porous systems that involve heat and gas transport processes. However, only a limited number of studies provide characterization of soil physical, thermal, and gas diffusion properties and the functional relationships of these properties under varying soil water contents, especially for soil mixtures, complicating optimization efforts. …

Health, Productivity, And Engagement: Using Modular Product Design To Integrally Improve The Workplace Environment, Xinyue Guo

Theses

With the fast pace of city life and workplace stress, there are growing concerns in relation to well-being and staying healthy. As a space that has relatively undefined functions in a work environment, breakrooms are increasingly expected to contribute to reducing these concerns. However, the vast majority of workplace breakrooms that exist are insufficiently designed achieving only basic functions such as sitting and eating. This thesis questions why existing workplace breakrooms are so neglected, when they have great potential to play a much more important role in the workplace. Firstly, this thesis discusses current literature and qualitative research on the …

Single-Rail Adiabatic Logic For Energy-Efficient And Cpa-Resistant Cryptographic Circuit In Low-Frequency Medical Devices, Amit Degada, Himanshu Thapliyal

Electrical and Computer Engineering Graduate Research

Designing energy-efficient and secure cryptographic circuits in low-frequency medical devices are challenging due to low-energy requirements. Also, the conventional CMOS logic-based cryptographic circuits solutions in medical devices can be vulnerable to side-channel attacks (e.g. correlation power analysis (CPA)). In this article, we explored single-rail Clocked CMOS Adiabatic Logic (CCAL) to design an energy-efficient and secure cryptographic circuit for low-frequency medical devices. The performance of the CCAL logic-based circuits was checked with a power clock generator (2N2P-PCG) integrated into the design for the frequency range of 50 kHz to 250 kHz. The CCAL logic gates show an average of approximately 48% …

Stimuli-Responsive Temporary Adhesives: Enabling Debonding On Demand Through Strategic Molecular Design, Nicholas D. Blelloch, Hana J. Yarbrough, Katherine A. Mirica

Dartmouth Scholarship

Stimuli-responsive temporary adhesives constitute a rapidly developing class of materials defined by the modulation of adhesion upon exposure to an external stimulus or stimuli. Engineering these materials to shift between two characteristic properties, strong adhesion and facile debonding, can be achieved through design strategies that target molecular functionalities. This perspective reviews the recent design and development of these materials, with a focus on the different stimuli that may initiate debonding. These stimuli include UV light, thermal energy, chemical triggers, and other potential triggers, such as mechanical force, sublimation, electromagnetism. The conclusion discusses the fundamental value of systematic investigations of the …

Effects Of Tendon Viscoelasticity On The Distribution Of Forces Across Sutures In A Model Tendon-To-Bone Repair, Yuxuan Huang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Tears to the rotator cuff often require surgical repair. These repairs often culminate in re-tearing when sutures break through the tendon in the weeks following repair. Numerous studies have been performed to identify suturing strategies that reduce this risk by balancing forces across sutures. However, the structural engineering basis for these approaches is still emerging, and the effects of tendon mechanics on load balancing is still unclear. Specifically, the effects of the viscoelastic nature of tendon on load sharing have not been established. With the aim of providing insight into this problem, this thesis studies how tendon viscoelasticity, tendon stiffness, …

Revised Semiempirical Approach To Predict The Occurrence Of Twinning In Titanium Alloys, Chirag Dhirajlal Rabadia, Syed Faraz Jawed, Jincheng Wang, Milind Siddhpura, Arti Siddhpura

Research outputs 2014 to 2021

A revised semiempirical approach, considering the average values of the valence electron to atom ratio (e/a̅) and a difference in atomic radii of alloying element/s and the base element (Δr¯), is proposed to predict the twin formation in titanium alloys. The revised e/ā versus Δr¯ diagram is plotted, considering the reported results of 90 titanium alloys fabricated using various processing methods. A new twin/slip boundary has been plotted and recommended based on the revised e/ā versus Δr¯ diagram. The conventional maximum limit reported for the twinning in titanium alloys is e/ā = 4.20; however, it has been found that twinning …

Mechanization: Planning And Selection Of Equipment, C. A. Rotz

IGC Proceedings (1977-2023)

The planning and selection of equipment for harvest and handling of forage crops can greatly impact the performance and profitability of a farm. The type and size of equipment used affects the harvested yield and nutritive value of the forage crop as well as production costs. Through interactions with other parts of the farm, these effects can impact market value of the forage, animal intake and performance, delays in other farm operations, other production costs, and ultimately farm profit. Standard procedures and relationships have been developed for determining the most appropriate equipment for a given production system. Because of the …

Conserved Forage (Silage And Hay): Progress And Priorities, R. E. Muck, K. J. Shinners

IGC Proceedings (1977-2023)

Forage conservation permits a better supply of quality feed when forage production is low. While haymaking and ensiling have been practiced for generations, research is still needed to 1) understand the processes affecting quality during harvesting and storage and 2) develop practical means to minimize losses and enhance quality.

Several trends in harvesting forages for silage are notable. Kernel processing of maize, once confined to Europe, has become popular in North America. Self-propelled forage harvesters have a larger share of the market due to more contract harvesting and larger farms. Larger harvesters, rakes and mergers help improve productivity and forage …
