Objective: The study was conducted to evaluate the anti-aging and anti-acne effect of and aliman ethanolic extract (AEE) in the form of peel off gel mask (PGM) on human skin. Methods: The formulation of PGM base was consisted of polyvinyl alcohol, glycerine, methylparaben, propylparaben, Carbomer 940, and distilled water (blank). The AEE (30%) was formulated in the PGM base and labeled as F1. The anti-aging and anti-acne tests were conducted by comparing the blank and the F1. The evaluation of anti-aging activity was conducted using skin analyzer apparatus. The aging parameters were moisture, evenness, pore size, black spot, and wrinkle of the skin. The anti-acne evaluation was conducted on color, shape, volume, and number of acne. The data were collected for 4 weeks. Results: The anti-aging evaluation of andaliman PGM showed that the and AEE PGM could pretend the skin moisture, skin evenness, small pore size, and declined in number of black spot and wrinkle. The anti-acne evaluation showed the healing of acne after 4 weeks treatment. Conclusion: It is concluded that and AEE PGM can be used as an effective anti-aging and anti-acne dosage form.

Positioning Method

The microporous on spinneret has the characteristics of high precision, small pore size and large quantity. Spinneret microporous finishing operation is mainly used for removing the burr formed on the spinneret silk surface after micropores drilling and punching. The burrs seriously affect the quality of the spinning fibers. Micropore spinneret finishing plays a vital role in improving the quality of processing micropore. This paper introduces a system consisting of the spinneret micropore fine machine,then focuses on fine machine positioning system and proposes a high-precision positioning method of the microporous.

PVA/chitosan nanofibers have been prepared by electrospinning method. A novel nanofibers mat was prepared in a various blend ratio of PVA to chitosan. The structure of PVA/chitosan nanofibers was examined by FTIR and SEM. The results showed that PVA/chitosan nanofibers were successfully formed. The result of FTIR indicates that PVA and chitosan exist in PVA/chitosan Nanofibers. SEM observation showed that the fiber has several hundred nanometers with a smooth surface. It also observed that fibers diameters decreased by increase percentage of chitosan, this occurs because of the conductivity of electrospun solution increase and the viscosity decrease. Reduction of fiber diameter followed by a decrease in pore size, this is a very important property of a membrane having a small pore size with high porosity. PVA/chitosan nanofibers have pH sensitive of swelling properties and better-swelling properties in acid conditions.

Primary Structures

Spheroidal weathering is an important form of rock weathering and has been attributed to chemical weathering from joint surfaces. However, the effects of the original rock structures on the processes of spheroidal weathering have not been well addressed. A columnar-jointed basalt contains primary structures that resulted from cooling, which exerted strong controls on the development of weathering with hard crusts. The primary structures were small-pore-size layers beneath the surfaces of columnar joints and some cross joints. Weathering of plagioclase was less intense in the small-pore-size layers, resulting in the exfoliation of surface parts of the layers and internal cracks.
