No supermassive black hole in M33?
(Science, 2001-08-10)We analyze optical long-slit spectroscopy of the nucleus of M33 obtained from the Space Telescope Imaging Spectrograph aboard the Hubble Space Telescope. Rather than the steep rise expected within the radius of influence ... -
Non-adiabatic transition of beams in gyrotrons through various magnetic field profiles
(Taylor & Francis, 1991)The achievement of efficiency enhancement in small-orbit gyrotrons by using depressed collector techniques requires precisely configured magnetic field profiles which present adiabatic as well as non-adiabatic transitions ... -
Non-hydrolytic release of iron from ferrienterobactin analogs by extracts of bacillus subtilis
(Elsevier: Biochemical and Biophysical Research Communications, 1980-12-31)The ferric chelates of the microbial siderophore enterobactin and of two synthetic analogs of enterobactin were sources of iron for growth of Bacillus subtilis WB2802. The ferrisiderophore reductase system in cell-free ... -
Nonlinear control of nonsquare multivariable systems
(Elsevier Science, 2001)This paper is concerned with the synthesis of a nonlinear state feedback law for nonsquare multivariable nonlinear systems. Previous approaches in the literature have solved this problem by (1) squaring the system by ... -
Nonlinear frequency-dependent selection at a single locus with two alleles and two phenotypes
(Springer Berlin / Heidelberg, 1999-10)The paper investigates the discrete frequency dynamics of two phenotype diploid models where genotypic fitness is an exponential function of the expected payoff in the matrix game. Phenotypic and genotypic equilibria ... -

Nonsplit dual-stage EDFA operating in the C- plus L-band
(Microwave and optical technology letters, 2004-07-30)The feasibility of a dual-stage erbium-doped fiber amplifier (EDFA) design for operation in both the C-band and the L-band is studied. The design is comprised of nonsplit single-pass amplification at both bands, thus ... -
Nonstationary behavior of collisionless shocks
(American Physical Society, 1972-01-03)Laboratory measurements indicate that a collisionless shock wave formed in a plasma-wind- tunnel device is nonstationary on the time scale of the ion gyroperiod. This behavior suggests a possible interpretation of recent ... -

A novel ultra-violet assisted anisotropic etching of plastic to realize micro-gears
(Elsevier: Sensors and Actuators A: Physical, 2004-09-21)An ultraviolet assisted chemical etching of plastic is reported in which the etching of PET substrates is anisotropic in the direction of light illumination. A strong solvent as di-methyl-formamide (DMF) is exploited to ... -
Nucleation characteristics and stability considerations
(Elsevier Science B.V., 2006)Flow boiling in microchannels and minichannels has received considerable attention in the past decade. The interest stems from the possibility of achieving the extremely high heat fluxes, over 1 kW/cm2, needed for future ... -

Numerical simulation of flow through microchannels in bipolar plate
(American society of mechanical engineers (ASME), 2005-06)In this paper, the flow through a serpentine microchannel with obstructions on wall is studied. Various obstruction geometries ranging from rectangular to triangular are considered. For each geometry pressure drop across ... -
Numerical simulation of growth of a vapor bubble during flow boiling of water in a microchannel
(Spring-Verlag, 2005-05)The present study is performed to numerically analyze the growth of a vapor bubble during flow of water through a microchannel. The complete Navier- Stokes equations, along with continuity and energy equations, are ... -
Numerical simulation of growth of a vapor bubble during flow boiling of water in a microchannel

Numerical study of an evaporating meniscus on a moving heated surface
(Journal of Heat Transfer, 2006-12)The present study is performed to numerically analyze an evaporating meniscus bounded between the advancing and receding interfaces on a moving heated surface. The numerical scheme developed for analyzing interface motion ... -
Numerical study of an evaporating meniscus on a moving heated surface
(American Society of Mechanical Engineers (ASME), 2004-07)The present study is performed to numerically analyze an evaporating meniscus on a moving heated surface. This phenomenon is similar to the one observed at the base of a vapor bubble during nucleate boiling. The complete ... -
Numerical study of the effect of inlet constriction on bubble growth during flow boiling in microchannels
(American society of mechanical engineers (ASME), 2005-06)Flow boiling through microchannels is characterized by nucleation of vapor bubbles on the channel walls and their rapid growth as they fill the entire channel cross-section. In parallel microchannels connected through ... -
Nutrient deprivation may be a poor inducer of apoptosis in the newborn rat eye
(Association for Research in Vision and Ophthalmology: Investigative Ophthalmology and Visual Science, 2003)Purpose: The hyaloid vasculature of the newborn rat eye persists after birth and regresses postnatally. One hypothesis is that regression occurs due to a decrease in blood flow to the hyaloid after retinal development and ...
