Study on recycling of waste water from spent water-soluble coolant
Kazuya Takada,Yasuo Kondo,Kenji Yamaguchi,Satoshi Sakamoto 대한기계학회 2010 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.24 No.1
We propose a recycling system that can recover the useful water from the spent water soluble coolant by using a surfactant and powdered activated carbon. The processing of about 70 liters of actual spent water soluble coolant yielded about 60 liters of clear water with 6.7 of pH and 0.0 of Brix value. About 120 liters of recycle water-soluble coolant was prepared by diluting an emulsion type cutting fluid 20 times with the recycle water. The recycle coolant has been showing the very similar Brix value and pH changes as those of virgin coolant until 100 days usage. The recycle coolant also showed the same potential to inhibit the progress of flank wear as that of virgin coolant. These facts indicate that the recycled water can be utilized as a dilutor of renewal water-soluble coolant.

The zodiacal light emission is the thermal emission from the interplanetary dust and the dominant diffuse radiation in the mid- to far-infrared wavelength region. Even in the far-infrared, the contribution of the zodiacal emission is not negligible at the region near the ecliptic plane. The AKARI far-infrared all-sky survey covered 97\% of the whole sky in four photometric bands with band central wavelengths of 65, 90, 140, and 160~$\mu$m. AKARI detected the small-scale structure of the zodiacal dust cloud, such as the asteroidal dust bands and the circumsolar ring, in far-infrared wavelength region. Although the most part of the zodiacal light structure in the AKARI far-infrared all-sky image can be well reproduced with the DIRBE zodiacal light model, there are discrepancies in the small-scale structures. In particular, the intensity and the ecliptic latitude of the peak position of the asteroidal dust bands cannot be reproduced precisely with the DIRBE models. The AKARI observational data during more than one year has advantages over the 10-month DIRBE data in modeling the full-sky zodiacal dust cloud. The resulting small-scale zodiacal light structure template has been used to subtract the zodiacal light from the AKARI all-sky maps.

The OxfordianBerriasian Birafu Formation in thesouthern Kurosegawa Belt (Permian accretion terrane), CentralShikoku, SW Japan, yields micro- and mega-faunas that contrib-ute to the biostratigraphy across the Jurassic-Cretaceous bound-ary. The type section consists of turbiditic sandstone and mudstonewith an upward-fining tendency in the lower members (A1-A3).with muddy limestone intercalations, whereas the upper memberC is characterized by a fine-grained turbiditic succession. Radi-olarians define the assemblage zones (AZ): Kilinora spiralis AZ(Oxfordian) in member A2, Loopus primitivus AZ (Tithonian) inthe upper part of member A3, and Pseudodictyomitra carpatica AZ(Berriasian - lower Valanginian) in members B2 and C. These giveat least an Oxfordian - Berriasian total time-range to the BirafuFormation. The mixed marine and brackish bivalve assemblage ofmembers B1 and B2 (lower part) comprises Grammatodon takien-sis Tamura, Pterotrigonia toyamai (Yehara) and Ctenoides tosanusKimura, the range of which is Late Jurassic to Earliest Creta-ceous, and Aguilerella nagatoensis (Ohta), Miltha japonica Tashiroand Isocyprina japonica Tashiro and Kozai, having an Early Cre-taceous range. The concurent range of Jurassic to Cretaceousbivalves and exclusively Cretaceous species is significant for theclarification of bivalve evolution across the Jurassic -Cretaceousboundary. The Berriasian appearance of Cretaceous marine andnon-marine bivalves takes place while Late Jurassic marine bivalvesboundary situated at its base.

We present a comparative study of CO and polycyclic aromatic hydrocarbon (PAH) emission toward a region including the massive star-forming regions of NGC 6334 and NGC 6357. We use the NANTEN $^{12}$CO($J$=1--0) data and the $AKARI$ 9 $\mu$m All-Sky diffuse map in order to evaluate the calibration accuracy of the $AKARI$ data. We confirm that the overall CO distribution shows a good spatial correspondence with the PAH emission, and their intensities exhibit a good power-law correlation with a spatial resolution down to 4$\rq{}$ over the region of 10$^\circ$$\times$10$^\circ$. We also reveal poorer correlation for small scale structures between the two quantities toward NGC 6357, due to strong UV radiation from local sources. Larger scatter in the correlation toward NGC 6357 indicates higher ionization degree and/or PAH excitation than that of NGC 6334.
