Low energy indium or gallium ion implantations to SiO2 thin films for development of novel catalysts
No full textSatoru Yoshimura, Masato Kiuchi, Yoshihiro Nishimoto, Makoto Yasuda, Akio Baba, Satoshi Hamaguchi, Low Energy Indium or Gallium Ion Implantations to SiO2 Thin Films for Development of Novel Catalysts, e-Journal of Surface Science and Nanotechnology, 2014, Volume 12, Pages 197-202, Released April 26, 2014, Online ISSN 1348-0391, https://doi.org/10.1380/ejssnt.2014.197, https://www.jstage.jst.go.jp/article/ejssnt/12/0/12_197/_article/-char/enIt has been demonstrated that indium (In) implanted silicon dioxide (SiO thin films catalyze a reaction of benzhydrol with acetylacetone. In this study, it is found that the threshold In ion incident energy for manifestation of the catalytic effect exists between 400 and 470 eV. Furthermore, a technique to implant gallium (Ga) to SiOfilms has been developed with highly controlled doses and injection energies for the formation of thin films that promote Ga catalysts. The efficiency of catalytic reactions by Ga implanted SiOthin films is yet to be improved. Unlike In implanted SiO2, the reason why no significant reaction was observed in the case of Ga implanted SiOfilms examined in this study seems that the Ga ion energy was so low that deposited surface Ga atoms should lack interactions with Si atoms for the manifestation of catalytic reaction. © 2014 The Surface Science Society of Japan
REVIEW OF: "Kawauchi Akio, Splitting a 4-manifold with infinite cyclic fundamental group, revised, J. Knot Theory Ramifications 22, No. 14, Article ID 1350081, 9 p. (2013)". [DE062730205]
No full textIn [Osaka J. Math. 31(3), 489-495 (1994; Zbl 0849.57018 )], the author stated that every closed connected
orientable 4-manifold M with infinite cyclic fundamental group is TOP-split, i.e. it is homeomorphic to
the connected sum (S1 × S3)#M1, M1 being a closed simply connected 4-manifold. However, in [Manuscr.
Math. 93(4), 435-442 (1997; Zbl 0890.57034)], Hambleton and Teichner obtained a counterexample to the
above general statement.
In the paper under review, the author makes a revision and proves that TOP-splittability holds under the
additional hypothesis that a finite covering of M is TOP-split. In particular, the original statement turns
out to be true in the case of indefinite intersection form, as well as for any smooth spin 4-manifold (with
infinite cyclic fundamental group).
The proof of the revised statement makes use of notions developed in [Knots in Hellas 98, Ser. Knots
Everything. 24 (World Scientific Publishing), 208-228 (2000; Zbl 0969.57020)] and [Atti Semin. Mat. Fis.
Univ. Modena 48(2), 405-424 (2000; Zbl 1028.57019)], together with the key result - proved in [Osaka J.
Math. 31(3), 489-495 (1994; Zbl 0849.57018 )] - that every closed connected orientable 4-manifold M with
infinite cyclic fundamental group is homology cobordant to (S1 × S3)#M1.
Consequences about surface-knots in S4 are also considered (see [J. Knot Theory Ramifications 4(2), 213-224
(1995; Zbl 0844.57020)])
Environmental Taxes and Productivity: Lessons from Canadian Manufacturing
No full texthttps://www.grips.ac.jp/list/jp/facultyinfo/yamazaki-akio/This paper investigates how environmental taxes affect manufacturing productivity by examining British Columbia’s revenue-neutral carbon tax. I develop a new hypothesis, the “Productivity Dividend Hypothesis,” to show that environmental taxes can positively affect productivity by recycling tax revenues to reduce corporate income taxes. This revenue-recycling increases investment and could raise productivity more than environmental taxes lower productivity by diverting resources from production. I evaluate this hypothesis using detailed confidential plant-level data. I find that the carbon tax lowers productivity, although this is offset to some extent by the revenue-recycling. For some plants, the policy generates a net gain in productivity.JEL Classification Codes: D22, H23, L6, Q5The author acknowledges generous funding from Productivity Partnership (PP) and Smart Prosperity Institute (SPI), supported by the Social Sciences and Humanities Research Council of Canada.technical repor
Data From: Ammonia volatilization from composting with oxidized biochar
No full textPlease cite as: Rachel Hestrin, Akio Enders, and Johannes Lehmann. (2020) Data From: Ammonia volatilization from composting with oxidized biochar. Cornell University eCommons Repository. https://doi.org/10.7298/p9wj-nk83Data in support of the following research: Animal manure, agricultural residues, and other sources of biomass can be diverted from the waste stream and composted into valuable fertilizer. However, composting often results in substantial N loss through NH3 gas volatilization. We investigated biochar’s capacity to improve NH3–N retention during composting of poultry manure and straw. After 7 weeks, total NH3–N loss from composting with unoxidized biochar was twofold and sixfold higher than N loss from composting with oxidized biochar and without biochar (307, 142, and 51 mg N g-1 N in the initial compost feedstocks, respectively). When cumulative NH3–N loss was calculated relative to CO2–C loss to account for differences in microbial activity, NH3–N:CO2–C loss from compost with oxidized biochar was 55% lower than from compost with unoxidized biochar (82% lower based on mass balance). Oxidized biochar particles removed from compost after 7 weeks retained 16.0 mg N g-1 biochar, compared to only 6.1 mg N g-1 retained by unoxidized biochar, suggesting that N retention by biochar particles provides a mechanism for reduced NH3–N loss. These data show that oxidized biochar enhanced microbial activity, doubled composting rate, and reduced NH3–N loss, and that biochar’s physiochemical characteristics modulate its performance in compost. In particular, the presence of oxidized surface functional groups—which can be increased artificially or through environmental weathering—appear to play an important role in key compost processes. This has implications for other natural and managed systems where pyrogenic organic matter may mediate biological activity and nutrient cycles
The potential business impacts of Semantic Web for system integration
No full textThesis (S.M.M.O.T.)--Massachusetts Institute of Technology, Sloan School of Management, Management of Technology Program, 2004.Includes bibliographical references (leaves 91-94).This thesis presents research about the potential business impacts of the Semantic Web. The concept of the Semantic Web is an expansion of the Web for computers, enabling them to comprehend the meaning of information. In addition, Semantic Web Services (SWS), the emerging convergence of Web Services with the Semantic Web, is the next major generation of the Web (and of the Internet), in which e-services and business communication become more knowledge-based and agent-based. The study arose out of a technology review of the Semantic Web and its current adoption. Following further analysis and research into business cases involving Semantic Web applications, the author focused specifically on the system integration business in an effort to understand the potential business impacts of the Semantic Web for system integration. In the system integration field, there are various trends for companies thinking about adopting the Semantic Web into the real business world. In this thesis, I offer answers to two questions: Why do system integrators need the Semantic Web, and how they should go about adopting it?by Akio Saita.S.M.M.O.T
