A polylactic acid composition comprising (A) a polylactic acid-series resin and (B) an acrylic triblock copolymer is prepared. The composition fulfills the following requirements: (1) the acrylic triblock copolymer (B) is a triblock polymer comprising (B1) a polymer block having a glass-transition temperature of not higher than 25° C., (B2a) a polymer block which has a glass-transition temperature of not lower than 60° C. and is bound to a terminal of the polymer block (B1), and (B2b) a polymer block which has a glass-transition temperature of not lower than 60° C. and is bound to another terminal thereof; (2) the polymer block (B1) comprises a main structural unit derived from an acrylate, and the polymer block (B2a) and the polymer block (B2b) independently comprise a main structural unit derived from a methacrylate; and (3) both of the weight-average molecular weights of the polymer block (B2a) and polymer block (B2b) are smaller than the weight-average molecular weight of the polymer block (B1). The polylactic acid-series resin (A) and the acrylic triblock copolymer (B) may form a phase separation structure.

Disclosed herein is a method and apparatus for moiré-free enhanced color halftone printing of color image separations for an arbitrary number of colorants. The method and apparatus utilizes a plurality of halftone screens, >4, to produce outputs that are moiré free and form hexagonal periodic rosettes. The relatively large number of screens can be used for enhanced printing applications, such as printing with high-fidelity colorants, light colorants, or special colorants, such as white, metallics and fluorescents. The method and apparatus provide for defining rosette fundamental frequency vectors V_R1, V_R2 that satisfy a length and sum requirement to meet visual acceptability standards according to |V_R1|>f_min, |V_R2|>f_min, and |V_R1±V_R2|>f_min; defining N halftone screens for colorants i=1, N, respectively possessing first and second frequency vectors (V_i1, V_i2), where no two screens possess identical fundamental frequency vector pairs; and selecting fundamental frequency vectors for the N halftone screens according to (V_i1, V_i2)=(m_i1V_R1+m_i2V_R2, n_i1V_R1+n_i2V_R2) for integer m's and n's, where at least one fundamental frequency vector or its conjugate must also satisfy one of the following: V_ik=V_R1, V_ik=V_R2, and |V_ik>2 max [|V_R1|, |V_R2|].

A liquid crystal display includes a first substrate, a first field generating electrode arranged on the first substrate and including first and second cutouts, and a second substrate facing the first substrate. A second field generating electrode is arranged on the second substrate and includes a third cutout, and a liquid crystal layer is interposed between the first and second field generating electrodes. A column spacer is interposed between the first and second substrates and is disposed in the first cutout region.

The invention discloses donkey milk cosmetic and a preparation method thereof. The donkey milk cosmetic is prepared by evenly mixing and treating multiple ingredients comprising over 30 percent of donkey milk. The added donkey milk serving as a main moisturizing agent, a nutrient, a whitening agent and an anti-ageing activating agent is used for preparing cosmetics such as moisturizing emulsion, skin cream, whitening and moisturizing emulsion, anti-wrinkling and anti-ageing nutrient essential milk, cleaning milk, bath foam, shampoo, hair conditioner, mask, soap and the like to promote metabolism of the skin, enhance blood circulation, improve the hydration degree of the skin, moisture the skin with elasticity, and recover the luster of the skin. The donkey milk cosmetic has the function ofrepair and activation, has better natural moisturizing and compacting functions on the skin, can inhibit the increment of pigment and thin freckles, has whitening effect, can reduce pores, regulate skin texture and promote the metabolism of skin epidermis cells, and has the function of delaying skin ageing. The donkey milk cosmetic serving as a unique and novel advanced skin-care product has strong physiological activity and remarkable efficacy.

Disclosed is a preparation method of a titanium plate for deep drawing. Titanium sponge which is not lower than the 0A level and meets the conditions that the O content is smaller than or equal to 0.05%, the N content is smaller than or equal to 0.006% and the Fe content is smaller than or equal to 0.05% is used as a raw material and subjected to smelting casting and forging, and two or more timesof drawing-out and/or upsetting are carried out in the forging process, so that a plate blank with a good structure and tiny texture is prepared; and then the plate blank is subjected to hot rolling,cold rolling and rolling in changed directions in combination with the steps of annealing and subsequent processing, so that the pure titanium plate with proper crystalline grains, qualified performance and a high Erichsen value is obtained. Through the method, the pure titanium plate can be made to be short in production procedure, high in efficiency and good in deep drawing performance.

In a thin beam directional Crystallization System configured anneal a silicon layer on a glass substrate uses a special laser beam profile with an intensity peak at one edge. The system is configured to entirely melt a spatially controlled portion of a silicon layer causing lateral crystal growth. By advancing the substrate or laser a certain step size and subjecting the silicon layer to successive “shots” from the laser, the entire silicon layer is crystallized. The lateral crystal growth creates a protrusion in the center of the melt area. This protrusion must be re-melted. Accordingly, the step size must be such that there is sufficient overlap between successive shots, i.e., melt zones, to ensure the protrusion is melted. This requires the step size to be less than half the beam width. A smaller step size reduces throughput and increases costs. The special laser profile used in accordance with the systems and methods described herein can increase the step size and thereby increase throughput and reduce costs.
