Advanced mobile satellite communications using COMETS satellite in MM-wave and Ka-band

Early in the 21st century, the demand for personal communications using mobile, hand-held, and VSAT terminals will rapidly increase. In a future system, many different types of services should be provided with one-hop connection. The Communications Research Laboratory (CRL) has studied a future advanced mobile satellite communications system using millimeter wave and Ka band. In 1990, CRL started the Communications and Broadcasting Engineering Test Satellite (COMETS) project. The satellite has been developed in conjunction with NASDA and will be launched in 1997. This paper describes the COMETS payload configuration and the experimental system for the advanced mobile communications mission

A Raman Spectroscopic Method of Evaluating Fat Crystalline States and Its Application in Detecting Pork Fat

International audienceRaman spectroscopy is one of the vibrational spectroscopies. Raman spectra of fats inform us of the vibrational states of acylglycerol molecules that reflect chemical structure, physical states, and the microenvironment at the molecular level. One of the great advantages of Raman spectroscopy is that it is less invasive; a sample can be studied in situ using laser light without pretreatment. Taking advantage of this spectroscopy, we investigated the crystalline states of meat fats and developed an in situ method of evaluating the degree of crystallinity and the crystalline polymorphs of fats. This method serves as a basis for such applications as the on-site quality measurement of meat fats and the species-specific detection of pork fat. This review describes the basics of Raman spectral analysis of the crystalline state of fat and its applications to meat products

Comparison of taste characteristics between koji mold–ripened cheese and Camembert cheese using an electronic tongue system

ABSTRACT: Koji mold, classified in the genus Aspergillus, is used to produce traditional Japanese fermented foods such as miso, soy sauce, and sake. In recent years, the application of koji mold to cheese ripening has attracted attention, and cheese surface-ripened with koji mold (koji cheese) has been studied. In this study, to evaluate the taste characteristics of koji cheese, an electronic tongue system was employed to measure the taste values of cheese samples ripened using 5 strains of koji mold in comparison with commercial Camembert cheese. All koji cheese samples exhibited lower sourness and greater bitterness, astringency, saltiness, and umami richness than the Camembert cheese samples. The intensity of each taste characteristic differed depending on the koji mold strain. These results indicate that koji cheese has a different taste value than conventional mold-ripened cheese. Furthermore, the results also indicate that various taste characteristics can be achieved by selecting different koji molds

Primary CNS lymphoma treated with radiotherapy in Japan: a survey of patients treated in 2005-2009 and a comparison with those treated in 1985-2004.

The aim of our study was to analyze changes over time in the characteristics, treatment, and outcome of patients with primary central nervous system lymphoma (PCNSL)
