Decomposition of nitric oxide on metallosilicates under a large excess oxygen condition with coexistence of a low concentration cetane

Catalytic removal of NO was conducted under the condition of large excess O₂ by using different kinds of metallosilicates having MFI structure. With coexistence of a low concentration of cetane, H-Fe-silicate, which had both acidity and redox property, exhibited the maximum performance among the catalysts tested at a fairly lower temperature range, around 350 °C, and the NO was totally converted. The temperature dependence of NO conversion was consistently similar to that of cetane combustion.     

Vacuum freezing type ice slurry production using ethanol solution 1st report: Measurement of vapor–liquid equilibrium data of ethanol solution at 20 °C and at the freezing temperature

In this study, an original method for the production of ice slurry from ethanol solution without using a refrigerator is proposed. This system has advantages compared with similar existing systems using materials other than ethanol solution. In this paper, the vapor–liquid equilibrium data of ethanol solution at 20 °C and at the freezing temperature are measured, which is necessary to calculate the COP of this ice slurry producing system. In the experiments, two experimental methods are proposed to measure the saturated pressure and the vapor composition of ethanol solution. Each method has an advantage in their operating temperature range. As a result, the vapor–liquid equilibrium diagrams of ethanol solution at 20 °C and at the freezing temperature, and approximations of saturated pressure of various concentrations of ethanol solution for varying liquid temperature, are obtained.     

Zero-subject Resolution Using Linguistic Constraints and Defaults: The Case of Japanese Instruction Manuals

This paper proposes a methodfor anaphora resolution ofzero subjects in Japaneseinstruction manuals based onboth the linguistic nature ofexpressions and the generalontology of the text type.In instruction manuals writtenin Japanese, zero subject isone of main reasons forambiguity of sentences.In order to resolve them,we examined the property ofseveral types of expressionsincluding some forms of verbalphrases and some conjunctive clauses.As a result, we have aset of constraints and defaultsfor zero subject resolution.We verified the precision and recall rateof the constraints and defaults with realexamples, and have found that they makequite good estimates with 97% precisionand 80% recall.

Renin-angiotensin system in an infant with malignant renovascular hypertension

The clinical and electromyographic signs of the misdirection syndrome after oculomotor palsy are described. Besides the previously described findings we found an increase of intraocular pressure dependent on the direction of gaze. In three young patients (16-26 years), we were able to demonstrate an aberrant reinnervation of the ciliary muscle, which was responsible for an increasing myopia in adduction. These observations supplement the previous concept of the misdirection syndrome.

Iterative algorithm of phase determination in digital holography for real-time recording of real objects

We propose a numerical method to obtain complex amplitude distribution of a three-dimensional (3D) object from a digital hologram. The method consists of two processes. The first process is to measure simultaneously a hologram of the 3D object and an object intensity distribution by two image sensors. These intensity distributions give us the amplitude and absolute value of phase of the 3D object at the image sensor plane. The second process is the determination of phase distribution by a proposed iterative process based on the criterion that the reconstructed 3D object is in focus and its conjugate reconstruction is out of focus. Numerical and experimental results show the effectiveness of the proposed method.
