대한수의학회 Journal of Veterinary Science 2002, 제 3권 제 2호 11 135-140 (6 pages)
A cross-sectional study was conducted to determine the prevalence of Histoplasma farciminosum in 2,907 carthorses using clinical and microbiological examinations at three towns (Debre Zeit, Mojo and Nazareth), Central Ethiopia, between December 1999 and January 2001. An overall prevalence of 26.2% (762/2,907) was recorded; the highest prevalence (39.1%) being recorded at Mojo whereas the lowest (21.1%) was recorded at Nazareth. The difference in prevalence among the three towns was highly... -
Control Efficacy of Bacillus velezensis AFB2-2 against Potato Late Blight Caused by Phytophthora infestans in Organic Potato Cultivation

한국식물병리학회 The Plant Pathology Journal 2021, 37권 6호 8 580-595 (16 pages)
Although late blight is an important disease in eco- friendly potato cultivation in Korea, it is highly depen- dent on the use of eco-friendly agricultural materials and the development of biological control technology is low. It is a necessary to develop an effective biocontrol agent to inactivate late blight in the field. AFB2-2 strain is a gram-positive with peritrichous flagella. It can uti- lize 20 types of carbon sources, like L-arabinose, and D- trehalose at 35°C. The optimal growth... -

The present study describes the bacterial blight of wal- nut, caused by Xanthomonas arboricola pv. juglandis (Xaj) in the northern Gyeongbuk province, Korea. Dis- ease symptoms that appear very similar to anthracnose symptoms were observed in walnut trees in June 2016. Pathogens were isolated from disease infected leaves, fruits, shoots, bud, flower bud of walnut, and cultured onto yeast dextrose carbonate agar plates. Isolated bac- teria with bacterial blight symptoms were character- ized for... -

Morphological (cyst shape, color, and sizes [length (L), maximum width (W), volume and “a” (L/W)]), structural (vulvar cone slope angle [VCSA], surface wrinkle [VCSW], cyst wall thickness, composition, and texture) and biological characteristics (fecundity, hatching, and emergence [number of second-stage juveniles (J2) from a cyst]) in preceding Heterodera glycines (Hg), currently- recorded H. sojae (Hs) and H. trifolii (Ht) were examined by microscopy. Cysts were lemon-shaped, indicating the... -
Tomato Yellow Leaf Curl China Virus Impairs Photosynthesis in the Infected Nicotiana benthamiana with βC1 as an Aggravating Factor
Tahir Farooq, Dandan Liu, Xueping Zhou, Qiuying Yang 한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2019, 35권 5호 12 521-529 (9 pages)
Tomato yellow leaf curl China virus is a species of the widespread geminiviruses. The infection of Nicotiana benthamiana by Tomato yellow leaf curl China virus (TYLCCNV) causes a reduction in photosynthetic activity, which is part of the viral symptoms. βC1 is a viral factor encoded by the betasatellite DNA (DNAβ) accompanying TYLCCNV. It is a major viral pathogenicity factor of TYLCCNV. To elucidate the effect of βC1 on plants’ photosynthesis, we measured the relative chlorophyll (Chl)... -
Ultrastructural Study on Induced Resistance of Cucumber Plants against Sphaerotheca fuliginea by Oligochitosan

with infection and a hypersensitive response. The host cell wall was thickened and deeply stained; several layers of papilla structure were produced under the cell wall; dark materials were deposited between the cell wall and plasmalemma; extrahaustorial plasmalemma was deeply stained and extrahaustorial matrix appositions had large deposits of electron-dense material; the cytoplasm was disordered, host organelles disintegrated and eventually the whole host cell disintegrated and necrotized. -
Different Profiles of the Negatively Stained Citrus Canker Bacterium Xanthomonas citri pv. citri Depending on Culture Media and Heavy Metal Stains

often showed relatively intact cell morphology and rather positively stained cells with a thin electron-dense stain depth around bacteria. The PTA-stained bacteria were characterized by the wrinkled cell surface where the stain was entrapped in grooves. In addition, distinct electron-dense stain depth was evident around the PTA-stained preparations. Numerous fimbriae could be mostly observed from the PTA-stained preparations of the two culture media, but not from the UA-stained preparations. -

Study on properties of eco-friendly reduction agents for the reduced graphene oxide method
Young-il Na, Young Il Song, Sun Woo Kim, Su-Jeong Suh 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 1 1-9 (9 pages)
We studied the basic properties and fabrication of reduced graphene oxide (rGO) prepared using eco-friendly reduction agents in the graphene solution process. Hydrazine is generally used to reduce graphene oxide (GO), which results in polluting emissions as well as fixed nitrogen functional groups on different defects in the graphene sheets. To replace hydrazine, we developed eco-friendly reduction agents with similar or better reducing properties, and selected of them for further analysis. In... -

exhibited vinculin expression throughout the cell body. The rougher and wrinkled surface morphology, higher elastic modulus and easy out-of-plane deformation associated with GF were considered to promote cell adhesion. Also, the biomineralization of GF was assessed by soaking in simulated body fluid, and the GF exhibited enhanced mineralization ability in terms of mineral deposition, which almost pervaded the entire GF surface. Our results suggest that graphene promotes cell adhesion, activity... -

최근 저항이나 캐패시터와 같은 수동소자를 PCB의 내층에 제조하는 임베디드 패시브 기술이 고성능의 IT 제품을 제조하는데 사용되고 있다. 그런데 임베디드 캐패시터는 정전용량 밀도가 낮아 회로소자로서의 전반적인 응용에 한계가 있다. 본 논문에서는 이러한 한계를 극복하기 위하여 wrinkle형의 전극과 유전체 층을 가진 새로운 임베디드 캐패시터를 제안하였다. FEM 기법을 사용하여 wrinkle형 임베디드 캐패시터의 정전용량 밀도를 평가하였다. Wrinkle형 임베디드 캐패시터는 기존의 평면형 임베디드 캐패시터에 비하여...
