potato dextrose agar (PDA; Becton, Dickinson and Company, Claix, France) medium under aerobic condition for 14 days according to published method (Ko et al., 2012). For inocu- lums, 10 ml of distilled water was added onto PDA formed with pycnidia of fungus. Conidia were harvested using a loop and filtered with a double folded mira-cloth. The con- centration of inoculum was adjusted to 1 × 10... Melanose, caused by Diaporthe citri, is one of severe diseases in citrus, a major economic resource in Jeju island. To reduce the usage amount of organic synthetic fungicide, bio-sulfur was tested as an alternative chemical to control citrus melanose in the present study. Direct antifungal activity of bio-sulfur against D. citri was determined through in vitro experiment using artificial nutrient media. Disease severity of melanose on bio-sulfur pretreated citrus leaves was lower than that on... -

the SP6C4 strain treatment and the numbers on the disc indicate each mutant based on the cluster number. (C) Paenibacillus larvae and Serratia marcescens served as entomopathogens. A two-layer method was employed to evaluate antibacterial activity. SP6C4 (10 6 cfu/ml, 10 μl) was inoculated on PDK medium. The en- tomopathogens were mixed into 25 ml of pre-cooled 0.2% PDK and overlaid onto the... Soil is the major source of plant-associated microbes. Several fungal and bacterial species live within plant tissues. Actinomycetes are well known for producing a variety of antibiotics, and they contribute to improving plant health. In our previous report, Streptomyces glo- bisporus SP6C4 colonized plant tissues and was able to move to other tissues from the initially colonized ones. This strain has excellent antifungal and antibacterial activities and provides a suppressive effect upon... -
Carbon-allotropes: synthesis methods, applications and future perspectives

technique or the arc plasma technique. Even commercial production has the same drawbacks as the laser irradiation method. These above men- tioned methods are referred as the I-G method for synthesis of fullerene. The I-G method is a combustion-based process for the synthesis of fullerenes, and it results in >98% pure fullerene or fullerene mixtures. The production conditions can be changed as... The element carbon has been used as a source of energy for the past few hundred years, and now in this era of technology, carbon has played a significant and very prominent role in almost all fields of science and technology. So as an honour to this marvellous element, we humans should know about its various forms of existence. In this review article, we shed light on all possible carbon-allotropes; similarities in their synthesis techniques and the starting materials; their wide range of... -
A review of the preparation and properties of carbon nanotubes-reinforced polymer compositess

A typical procedure for the preparation of a composite by melt mixing method is as follows: CNTs are directly added to epoxy resin and then sonicated using an ultrasonic machine at an elevated temperature. Curing agent is added into the mixture and the mixture is degassed in a vacuum oven. Finally, mixture is injected into sample molds and is cured in an oven [10]. A typical procedure for... -

wear testing machine using the ball-on disk method. A zirconia ball-type tip was used for the test, and the friction coeffcient and wear loss data for each specimen were obtained by sliding the zirconia ball on a track of 11.5 mm radius with the speed of 0.04 m/s for 7200 s, and the applied load was 5 kgf. To confrm the reproducibility of the data, tests were conducted fve times. The friction... Carbon/carbon (C/C) composites are acknowledged as high performance materials because of their good mechanical properties such as wear resistance, even at the higher temperature, due to their low thermal expansion [1-5]. Their hardness and light weight in addition to their superior mechanical properties at high temperature make C/C composites the best material to make brakes for aircrafts and other high weight vehicles. Accordingly, a number of studies have been conducted on the performance of... -

The analysis was conducted to identify homogeneous subgroups of participants on the basis of their quality of life, as indicated by their mean profiles of SWBI-R scores, such that within-group variation would be minimized relative to between-group variation (Aldenderfer &... This study examined the patterns of psychosocial adaptation to chronic illness and disability(CID), defined in terms of subjective well-being and coping strategies in a sample of 100 individuals with various CID conditions. Cluster analysis revealed four distinct clusters of respondents, suggesting a varying degree of psychosocial adaptation. These clusters were labeled succumbing(n=9), surviving(n=40), resilient(n=41), and thriving(n=10). Our findings indicate that resilient and succumbing...
