Effect of Overlapping Fe/TiO2 Coated on Netlike Glass Disc and Cu Disc on CO2 Reduction

Fe-doped TiO2 (Fe/TiO2) film photocatalyst was prepared by sol-gel and dip-coating process to respond to the visible spectrum. Netlike glass fiber and Cu disc that are base materials used for coating Fe/TiO2 were investigated to promote the CO2 reduction performance of the photocatalyst. The prepared Fe/TiO2 film coated on netlike glass fiber and Cu disc was characterized by scanning electron microscope (SEM) and electron probe micro analyzer (EPMA). Additionally, the CO2 reduction experiment using Fe/TiO2 film coated on netlike glass disc, Cu disc, and their overlap was carried out by illuminating an Xe lamp or without ultraviolet (UV) light, respectively. As a result, the concentration of produced CO increases by Fe doping irrespective of base material used under the illumination condition with UV light as well as without UV light. The peak concentration of CO for the Fe/TiO2 double overlapping is approximately 1.5 times as large as the Fe/TiO2 single overlapping under the illumination condition with UV light due to the promotion of electron transfer between the two overlapped photocatalysts. However, the promotion ratio is approximately 1.1 times under the illumination condition without UV light

An allometric smoothing function to describe the relation between otolith and somatic growth over the lifespan of walleye pollock (Theragra chalcogramma)

We propose a new equation to describe the relation between otolith length (OL) and somatic length (fork length [FL]) of fish for the entire lifespan of the fish. The equation was developed by applying a mathematical smoothing method based on an allometric equation with a constant term for walleye pollock (Theragra chalcogramma) —a species that shows an extended longevity (>20 years). The most appropriate equation for defining the relation between OL and FL was a four-phase allometric smoothing function with three inflection points. The inflection points correspond to the timing of settlement of walleye pollock, changes in sexual maturity, and direction of otolith growth. Allometric smoothing functions describing the relation between short otolith radius and FL, long otolith radius and FL, and FL and body weight were also developed. The proposed allometric smoothing functions cover the entire lifespan of walleye pollock. We term these equations “allometric smoothing functions for otolith and somatic growth over the lifespan of walleye pollock.

Successful treatment of corneal wasp sting-induced panuveitis with vitrectomy

BACKGROUND: This study aims to present the management and clinical findings of a case of corneal wasp sting and to report the outcome of corneal change and panuveitis after vitrectomy. FINDINGS: Clinical findings, anterior segment photographs, corneal endothelial changes, and medical treatment of corneal wasp sting-induced panuveitis are presented. A 95-year-man was stung by a wasp on his left cornea. A severe conjunctival hyperemia, marked corneal edema, corneal epithelial defect, and uveitis developed. As soon as the patient visited our clinic, topical corticosteroid and antibiotics were given, but corneal endothelial damage and uveitis did not improve. Anterior chamber irrigation was performed with oxiglutatione solution to rinse out the wasp venom. Corneal edema and anterior uveitis improved but the endothelial cell density gradually decreased and the vitreous opacity deteriorated. Therefore, a 23-gauge vitrectomy was performed. Subsequently, the corneal edema and panuveitis improved. CONCLUSIONS: Vitrectomy may be an effective treatment for corneal endothelial damage and endophthalmitis induced by a corneal wasp sting

CO₂ Reduction Characteristics of Cu/TiO₂ with Various Reductants

Cu-doped TiO2 (Cu/TiO2) film photocatalyst was prepared by combination of sol-gel and dip-coating process and pulse arc plasma method. The effect of Cu/TiO2 photocatalyst on CO2 reduction performance with reductants of H2O and H2 or NH3 was investigated. In addition, the overlapping two Cu/TiO2 coated on netlike glass discs were also investigated. The CO2 reduction performance of Cu/TiO2 film was tested under illumination of Xe lamp with or without ultraviolet (UV) light, respectively. As to the condition of CO2/H2/H2O, the best CO2 reduction performance has been achieved under the condition of CO2/H2/H2O = 1:0.5:0.5 with UV light illumination as well as without UV light illumination. The theoretical molar ratio of CO2/H2O or CO2/H2 to produce CO is 1:1. Since the molar ratio of CO2/H2/H2O = 1:0.5:0.5 can be regarded as the molar ratio of CO2/total reductants = 1:1, it is believed that the results of this study follow the reaction scheme of CO2/H2O and CO2/H2. On the other hand, as to the condition of CO2/NH3/H2O, the best CO2 reduction performance has been achieved under the condition of CO2/H2/H2O = 1:1:1 with UV light illumination as well as without UV light illumination

The Development of Management Accounting and the Asian Position

由厦门大学会计发展研究中心提供的第五届会计与财务问题国际研讨会——当代管理会计新发展论文集中的第一部分主题报告人02At present, management accountants all over the world are facing critical problems concerning intensive competition, increased risk and social responsibility. Although they have recently devised various novel methods and models, they are not yet likely to resolve the problems even if these novelties led to increased efficiency and effectiveness. We should reflect on the future prospects for management accounting with more sincere concern for environmental protection and peaceful and stable society rather than for efficiency and effectiveness. Those who stress only efficiency and effectiveness must actually suffer from their dreadful impact on the environment and public peace, although it is very difficult to integrate them with social considerations
