This study was determined the hair growth effect and mode of action of a complex extract (abelmo), extracted from various natural plants including Acorus calamus var. angustatus. 30 six-week old C57BL/6 mice were randomly assigned into three treatment groups with ten mice per treatment group repeatedly. The treatment group is a control group, and was classified into saline-applied, minoxidil 5%-applied, and abelmo-applied groups. Hair growth started from the abelmo-applied and minoxidil 5% -applied groups on the 9th day, compared to the saline-applied group. Hair growth rate was 17.06% and 19.15% in those two groups, respectively, and the abelmo-applied group's hair growth rate was higher. The density, length and thickness of hair were significantly higher in the order of abelmo-applied group, minoxidil 5%-applied group and saline-applied group on the 9th day, and hair root was strongly maintained in the abelmo-applied group. The density, length and thickness of hair in the abelmo-applied group were significantly higher by 599.8, 122.2 and 181.8% on the 9th day compared to the saline-applied group, and 166.7, 171.4 and 200.2% on the 12th day, and 136.6, 216.9 and 180.7%, respectively on the 15th day. As for hair follicle and the length of hair shaft from the dosal skin histopathology manifestation, the abelmo-applied group was more excellent than the saline-applied group and minoxidil 5%-applied group. This result actually confirmed the fact that abelmo promotes hair growth and strongly maintains hair root simultaneously.

Uniformity and performance characteristics of LTPS TFTs are important parameters for making advanced active-matrix displays. In this paper, we describe an SLS-based crystallization approach for producing orientation-controlled Si films with reduced concentrations of planar defects that stand to potentially deliver unprecedented levels of device uniformity and performance. Specifically, a 2-step process referred to as hybrid SLS has been developed that produces a variety of high-quality {100} surface-oriented Si films.

Directionally solidified Si films obtained via line-scan SLS can lead to attainment of high-mobility TFTs. The crystallographic texture of the resultant materials can potentially be an important factor because the spatial details thereof may impact the overall device uniformity. Here, we present EBSD analysis of these materials that reveal the existence of relatively large domains with different textures and differing amounts of defects, which in turn, may adversely affect device uniformity.

Line-scan SLS of thin Si films permits the attainment of low-defect-density Si films with a directionally solidified microstructure. This paper deals with: (1) identifying and examining the structural defects that are found in the resultant material, (2) how the spatial variations in the type and density of the observed defects may potentially affect the overall uniformity of the resulting devices, and (3) some technical options that may be applied in order to potentially alleviate the situation.

Harmonic current was measured for a dummy cell with various values of resistance, and the procedure developed through the measurements was applied to the investigation of effects of the amplitude of applied frequency and applied potential on the harmonic current of a stainless steel and a carbon steel in chloride containing solutions. From the measurements of harmonic current in the dummy cell, the optimum values of applied frequency and applied potential in harmonic current measurements were found to be 1 mHz and 20 mV (or lower), respectively. Increase in harmonic current with applied frequency was observed in the case where the level of harmonic current is low as in a stainless steel. Decrease in polarization resistance was also noted in this corrosion system with either increasing applied frequency or decreasing applied potential. However, no obvious effects of applied frequency was observed on harmonic current and polarization resistance in a carbon steel in which the level of harmonic current is high.
