Role of the ubiquitin-proteasome pathway in the inner ear : identification of an E3 ubiquitin ligase for Atoh1
(Massachusetts Institute of Technology, 2014)Atoh1, the proneural basic-helix-loop-helix transcription factor, is critical for the differentiation of inner ear hair cells. Hair cells do not develop in mice that lack Atoh1, and overexpression of the transcription ... -
The role of thrift institutions in Boston's housing markets.
(Massachusetts Institute of Technology, 1974) -
The role of time in negotiations.
(Massachusetts Institute of Technology, 1979) -
Role of tip clearance flow on axial compressor stability
(Massachusetts Institute of Technology, 2002)An examination of the fluid dynamic phenomena that link tip clearance flow to the formation of short length-scale (spike) rotating stall disturbances has been carried out. It is found that the onset of growth in tip clearance ... -
The role of topography in the emergence of African savannas
(Massachusetts Institute of Technology, 2003)The coexistence of trees and grasses in savannas are not well understood even though savannas occupy a wide area of West Africa. In this study, a hypothesis is proposed to investigate the question of how trees and grasses ... -
Role of topoisomerase I in the stability of the ribosomal DNA of Saccharomyces cerevisiae
(Massachusetts Institute of Technology, 1998) -
Role of torque in haptic perception of virtual objects
(Massachusetts Institute of Technology, 2001)An experimental study was performed to determine the role of torque feedback in haptic perception of object location within virtual environments. The experimental setup consisted of two Phantom haptic interfaces connected ... -
The role of type I collagen heterotrimers and homotrimers in mechanical strength and collagen cleavage
(Massachusetts Institute of Technology, 2014)Collagen is a crucial structural protein, formed through a hierarchical assembly of molecules, arranged in collagen fibrils, which constitutes the basis for larger-scale fibers. Normal type I collagen is a heterotrimer ... -
The role of U1 and snRNP in pre-mRNA splicing
(Massachusetts Institute of Technology, 1996) -
The role of uncertainty in balancing biological and chemical health risks in drinking water chlorination
(Massachusetts Institute of Technology, 1995) -
The role of unfolded states in collagen degradation
(Massachusetts Institute of Technology, 2010)Excessive collagen degradation (collagenolysis) has been implicated in a series of diseases such as tumor metastasis, atherosclerosis and arthritis. There are still several unresolved questions about the mechanism of ... -
The role of values & practical identities in mental wellbeing
(Massachusetts Institute of Technology, 2019)More than 300 million people in the world suffer from depression. While traditional psychotherapies like cognitive behavioral therapy (CBT) continue to be effective for treating depression, a newer therapy known as acceptance ... -
Role of variance in manufacturing system design : the impact on capacity planning and capital investment decisions
(Massachusetts Institute of Technology, 1997) -
The role of vegetation dynamics in the climate of West Africa
(Massachusetts Institute of Technology, 2000)The climate of West Africa exhibits significant variability at the time scale of decades. The persistent drought of the past three decades is an example of such variability. This study investigates the role of vegetation ... -
The role of venture capital in China's technology entrepreneurship development
(Massachusetts Institute of Technology, 2003)China has placed the commercialization of science and technology innovations as one of the nation's most important long-term development strategies. In the birthplace of venture capital (VC), venture investment has been ... -
The role of venture capitalists in financing and developing high-technology start-ups
(Massachusetts Institute of Technology, 2001)This dissertation addresses the interaction between venture capitalists (VCs) and start-up development through three essays. A common theme is that VCs serve important extra-financial and information brokering roles. In ... -
The role of vessel collapse on the flow of aqueous humor
(Massachusetts Institute of Technology, 1981) -
Role of viscoelasticity and non-linear rheology in flows of complex fluids at high deformation rates
(Massachusetts Institute of Technology, 2013)We combine pressure, velocimetry and birefringence measurements to study three phenomena for which the fluid rheology plays a dominant role: 1) shear banding in micellar fluids, 2) extension-dominated flows in microfluidic ... -
The role of viscosity in stratified rotating fluids
(Massachusetts Institute of Technology, 1964) -
The role of vortices in the formation of the solar system
(Massachusetts Institute of Technology, 1998)An important part of explaining planet formation is understanding how small particles accumulate into larger bodies. Gas vortices are suggested as a mechanism to enhance the coagulation of dust particles in the solar nebula. ...
