(n,nʹ[gamma]) reactions in 6̳3̳,̳6̳5̳Cu and background in 0[nu] [beta] [beta] experiments
(Massachusetts Institute of Technology, 2008)Measurements of (n, xnʹ[gamma]) reactions in Cu are important for understanding neutroninduced background for certain underground double beta decay experiments. Neutroninduced gammas are a contribution to background for ... -
N-ary level in the software test vehicle for the Infoplex database computer
(Massachusetts Institute of Technology, 1982) -
Nano-contact printing of DNA monolayers
(Massachusetts Institute of Technology, 2005)Technology today is directed towards building smaller devices. To accommodate this development, printing methods are needed. Some printing methods that are used include lithography, micro-contact printing, and inkjet ... -
Nanofiber characterization of self-assembling peptides RAD16 and RID 12
(Massachusetts Institute of Technology, 2004)Self-assembling peptides are quickly proving themselves useful in tissue engineering and most recently, electronics. Self-assembling peptides have been shown to form a network of nanofibers that can be used in scaffold ... -
Nanoparticle Superlattice Processing: Monodispersed Building-Blocks & Single Crystal Films
(Massachusetts Institute of Technology, 2023-06)Nanocomposite tectons (NCTs) offer a versatile method for systematically modulating material properties at the nanoscale. These building blocks are created by grafting nanoparticles with end-terminated polymers comprising ... -
Nanoparticle-chaperoned urinary 'synthetic biomarkers' for profiling proteases in cancer
(Massachusetts Institute of Technology, 2012)Many biomarker-based diagnostics have poor predictive value because of their dependence on naturally occurring endogenous biomolecules to indicate disease. This work presents a diagnostic platform that uses nanoparticles ... -
Nanoscale properties of poly(ethylene terephthalate) vascular grafts
(Massachusetts Institute of Technology, 2004)Vascular grafts are prosthetic tubes that serve as artificial replacements for damaged blood vessels. Poly(ethylene-terephthalate), PET, has been successfully used in large diameter grafts; however, small caliber grafts ... -
Narrow frequency-band laser with optical feedback
(Massachusetts Institute of Technology, 2005)In this paper we discuss the construction of a narrow frequency-band laser with optical feedback. We use a distributed Bragg reflector (DBR) laser diode centered at the cesium D₂ transition wavelength, [gamma] = 852 nm. ... -
The narrow gauge railway versus the standard gauge
(Massachusetts Institute of Technology, 1888) -
National product design competition for high school students
(Massachusetts Institute of Technology, 2009)Sir Ken Robinson said, "We don't grow into creativity, we grow out of it or rather we're educated out of it."' Throughout my education I have found this statement to be true especially in it's relation to high school ... -
National technological and military prestige heavily influenced the development of early United States space policy
(Massachusetts Institute of Technology, 2002)The purpose of this thesis is to discuss the relationship between U.S. space policy and: 1) national technological prestige 2) military superiority 3) and ultimately the political competition between the United States and ... -
Natural carbonaceous materials for use in transparent Joule heaters
(Massachusetts Institute of Technology, 2019)Natural carbonaceous materials have the potential to be used in a new class of more economically and environmentally sound electronic devices due to their tunable conductivity as well as robust mechanical and thermal ... -
Natural convection analysis of the MITR-II during loss of flow accident
(Massachusetts Institute of Technology, 1977) -
Natural frequencies and damping factors for a cable with lumped masses
(Massachusetts Institute of Technology, 1982) -
The natural interface between bone and tendon : SEM observations of the enthesis in an ovine model
(Massachusetts Institute of Technology, 2010)The present study investigates the naturally occurring interface between bone and tendon using scanning electron microscopy. The micrographs revealed a cartilaginous layer, 100 to 400 [mu]m thick apposing bone, that contained ... -
Natural variability in eastern tropical Pacific nitrous oxide emissions
(Massachusetts Institute of Technology, 2018)Nitrous oxide (N2O) is a powerful greenhouse gas and ozone depleting substance, but its natural sources remain poorly constrained. Marine emissions are likely much higher than IPCC estimates predict, due to unusually high ... -
The nature and effects of hiring practices in the construction industry
(Massachusetts Institute of Technology, 1959) -
Nature's engineering : a blueprint for efficient aircraft design
(Massachusetts Institute of Technology, 2011)The flight of birds inspired engineers like Leonard da Vinci and Wilbur and Orville Wright to design aircraft that mimic the behavior they observed. The success of the Wright brothers' first controllable aircraft ushered ... -
Naval additive manufacturing : bridging the gap between research and implementation
(Massachusetts Institute of Technology, 2019)Additive manufacturing (AM), commonly known as three-dimensional printing, presents numerous advantages over traditional production methods, including design-to-end-use process reduction and on-demand generation of needed ... -
Naval applications of enhanced temperature, vibration and power monitoring
(Massachusetts Institute of Technology, 2015)Navy ships require reliable information regarding their power and mechanical systems in order to perform their mission effectively. While today's shipboard systems are quite sophisticated, there are areas for improvement ...
