Abstract Research on controlled drug delivery for cancer chemotherapy has focused mainly ways to deliver existing anti-cancer compounds specified targets, e.g., by conjugating them with magnetic particles or encapsulating in micelles. Here, we show that an iron-salen, i.e., μ-oxo N , N' - bis(salicylidene)ethylenediamine iron (Fe(Salen)), but not other metal salen derivatives, intrinsically exhibits both character and activity. X-Ray crystallographic analysis first principles calculations...
Abstract Questions Have vascular plants shifted in elevation along a tropical mountain gradient on Mauna Loa, Hawai'i over the past 40 yr? If so, do native and non‐native species differ their shifts of mean range, upper limit or lower limit? Location Volcanoes National Park, southeast slope Hawai'i. Methods We resurveyed an belt transect vegetation plots that was first surveyed early 1970s. Differences between 1970 2010 were calculated for 69 plant species’ elevation, limit, range....

First, performances various types nonthermal plasma reactors for NO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> reduction were compared. It was shown that surface-discharge have as high capabilities pulse-powered wire-cylinder reactors. Second, treatment using reactor with a NO-adsorbent zeolite 13X performed. Thermal desorption employed regeneration zeolite. The 350 ppm...
Every year, stricter regulations are imposed on diesel engine emissions. It is difficult to satisfy these only by improving the combustion improvement techniques in near future. We require highly effective postprocessing technology for removal of particulate matter (PM) such as carbonaceous from Ceramic filter (DPF) has emerged a leading PMs. However, PM incineration or regeneration major problem encountered use DPFs at low temperatures. In this paper, pilot-scale experiments conducted...

In order to estimate multispectral images of the absorption and scattering properties in cerebral cortex vivo rat brain, we investigated spectral reflectance estimated by Wiener estimation method using a digital RGB camera. A Monte Carlo simulation-based multiple regression analysis for corresponding absorbance at nine wavelengths (500, 520, 540, 560, 570, 580, 600, 730, 760 nm) was then used specify parameters brain tissue. this analysis, concentrations oxygenated hemoglobin that...
Nonthermal plasma (NTP) desorption is used in NOx aftertreatment systems for diesel engine exhaust gas. The authors conducted experiments both NTP and thermal desorptions under similar conditions electric power levels. results confirm that NO, NO2, CO2 are desorbed by the at lower gas temperatures, while total amount of nearly same processes. Moreover, NO2 greater than desorption. more significant rapid
As the regulations governing diesel engine emissions have become more stringent, it has difficult to fulfill these new requirements by only using techniques that improve combustion. Therefore, effective aftertreatment technology is needed, particularly for particulate matter. Although ceramic filter (DPF) a leading in automobiles, their implementation marine engines operated with oil (A-heavy fuel oil) containing sulfur presents problem, terms of soot removal or regeneration. In this study,...
Because the regulations governing diesel engine emissions are becoming more stringent, effective aftertreatment is needed for particulate matter. Although filters (DPFs) a leading technology used in automobiles, there remains problem with DPF regeneration marine engines that use heavy oil fuel. In present study, pilot-scale experiments were conducted to develop oxidation using by nonthermal-plasma-induced ozone injection. It has been shown depends on exhaust gas temperature, and can be...
We investigated a quantitative imaging of reduced scattering coefficients μs'( λ) and the absorption μa( in vivo cortical tissues range from visible to near-infrared (NIR) wavelengths based on diffuse reflectance spectral technique. In this method, images tissue are acquired at nine (500, 520, 540, 560, 570, 580, 600, 730, 760 nm). A multiple regression analysis aided by Monte Carlo simulation for absorbance spectra is then utilized estimate optical tissue. This calculates concentration...
We simultaneously measured the diffuse reflectance spectra and transmittance of in vitro rat cerebral cortical tissue slices perfused with artificial cerebrospinal fluid (aCSF) wavelength range from 500 to 900 nm. An ischemia-like condition was induced by oxygen/glucose deprivation (OGD) aCSF. Diffuse were decreased increased, respectively, during OGD. Spectral data reduced scattering coefficients absorption estimated inverse Monte Carlo simulation for light transport tissue. As OGD,...
Atmospheric-pressure nonequilibrium nonthermal plasma hybrid exhaust gas aftertreatment systems that do not utilize precious metal catalysts, harmful ammonia, etc., have been developed by the authors.
