The von Koch snowflake curve is a mathematical curve, and is being used as antenna in wireless communications. There are various variants of the Koch curve scattered in literature. This paper attempts to present a critical review of the variants of Koch curve.

Dendrobium officinale is one of the most important Chinese medicinal herbs. Polysaccharides are one of the main active ingredients of D. officinale. To identify the genes that maybe related to polysaccharides synthesis, two cDNA libraries were prepared from juvenile and adult D. officinale, and were named Dendrobium-1 and Dendrobium-2, respectively. Illumina sequencing for Dendrobium-1 generate...

BACKGROUND Emerging evidence suggests that an increased arginase activity is involved in vascular dysfunction in experimental animals. Zingiber officinale Roscoe, commonly known as ginger, has been widely used in the traditional medicine for treatment of diabetes. OBJECTIVES This study aimed at investigating the effects of the hydroalcoholic extract of Z. officinale on arginase I activity and...

This study aims to investigate the difference in quality of rice wine fermented with different yeasts (Saccharomyces cerevisiae FBKL2.8022 (Sc) and Wickerhamomyces anomalus FBKL2.8023 (Wa)) by adding Dendrobium officinale (D. officinale). The results showed that addition D. improved physicochemical indices sensory scores promoted release active substances from officinale. increased types conten...

The crowding of wireless band has necessitated the development of multiband and wideband wireless antennas. Because of the self similar characteristics, fractal concepts have emerged as a design methodology for compact multiband antennas. A Koch-like fractal curve is proposed to transform ultra-wideband (UWB) bow-tie into so called Koch-like sided fractal bow-tie dipole. A small isosceles trian...

OBJECTIVES The purpose of this study was to characterize anisotropy in the triangle of Koch by relating electrophysiology with anatomy. BACKGROUND Atrioventricular (AV) node fast and slow pathway characteristics have been suggested to be due to nonuniform anisotropy in the triangle of Koch. METHODS During atrial pacing, we determined the electrical activity within the triangle of Koch by mu...

Herbal plant supplements are one of the important natural growth promoters used as alternatives to commercial antibiotics. This experiment was conducted to investigate the effects of spice and Herbal plant products on the growth, carcass qualities, biochemical, Microbial Count and immune response factors in Japanese quail meat. A total of 360 fourteen-day-old Japanese quails female were randoml...

Fractal objects have some unique geometrical properties. One of them is the possibility to enclose in a finite area an infinitely long curve. The resulting curve is highly convoluted being nowhere differentiable. One such curve is the Koch curve. In this paper, the behavior the Koch monopole is numerically and experimentally analyzed. The results show that as the number of iterations on the sma...
