한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2014, 30권 4호 15 450-455 (6 pages)
This study sought to control the root-knot nematode (RKN) Meloidogyne incognita using benign organo-chemicals. Second-stage juveniles (J2) of RKN were exposed to dilutions (1.0%, 0.5%, 0.2%, and 0.1%) of acetic acid (AA), lactic acid (LA), and their mixtures (MX). The nematode bodies were disrupted severely and moderately by vacuolations in 0.5% of MX and single organic acids, respectively, suggesting toxicity of MX may be higher than AA and LA. The mortality of J2 was 100% at all concentrations... -

한국보훈학회 한국보훈논총 2012, 제 11권 제 4호 (통권 25집) 9 263-317 (55 pages)
지금까지의 성경에 나타난 하나님의 상징의 의미와 특성에 관한 여러 가지 논의들 을 살펴보았다. 상징(Symbol)이란 겉으로 드러난 객관적 존재(형식)의 차원을 넘어서 초경험적 세계에 감추어진 주관적 본질(내용)의 차원을 지닌 것으로서, 그것이 처한 맥락 속에서 인식주체의 해석에 따라 다양한 의미를 나타내고, 독특한 정서와 감정을 불러일으킨다. 따라서 하나님의 상징성 분석은 육에 속한 인간에게 영으로서의 존재하 는 하나님을 깨닫고 체험하도록 해준다는 점에서 큰 의미가 있다. 또한 성경적 상징주 의 해석은 영적 진리를... -

In this study, composite PAN-based ACNFs embedded with MgO and MnO2 were prepared by the electrospinning method. The resultant pristine ACNFs, ACNF/MgO and ACNF/MnO2 were characterized in terms of their morphological changes, SSA, crystallinity and functional group with FESEM-EDX, the BET method, XRD and FTIR analysis, respectively. Results from this study showed that the SSA of the ACNF/MgO composite (1893 m2 g?1) is significantly higher than that of the pristine ACNFs and ACNF/MnO2 which is... -

This study synthesized pure anatase carbon doped TiO₂ photocatalysts supported on a stainless steel mesh using a sol-gel solution of 8% polyacrylonitrile (PAN)/dimethylformamide (DMF)/TiCl₄. The influence of the pyrolysis temperature and holding time on the morphological characteristics, particle sizes and surface area of the prepared catalyst was investigated. The prepared catalysts were characterized by several analytical methods: high resolution scanning electron microscopy (HRSEM), energy... -

recently to increase catalytic activity in the o-nitroaniline reduction to NaBH4 and Raman activity in test molecules as p-aminothiophenol [1]. Other authors showed that the rGO in combination with carbon nanotubes has the properties of supercapacitors [2]. Mao et al. [3] obtained a gas sensor type field defect transistor of high sensitivity at low concentrations, using sheets of rGO. On the other hand, rGO linked with Cu2O nanocrystals is capable of removing dye pollution from wastewater [4]. -

Physical and electrochemical qualities were analyzed after KOH activation of a direct methanol fuel cell using needle coke as anode supporter. The results of research on support loaded with platinum-ruthenium suggest that an activated KOH needle coke container has the lowest onset potential and the highest degree of catalyst activity among all commercial catalysts. Through an analysis of the CO stripping voltammetry, we found that KOH activated catalysis showed a 21% higher electrochemical...
