The goal of this research is to describe and analyze women’s wear in the late Qing Dynasty andearly Republic Period(late 19th c.—early 20th c.),with an emphasis on the daily informal orsemi-formal wear,though some formal or ceremonial costumes such as wedding dress will also beincluded.This study will use Chinese costumes and textiles from many museums to fill in theblanks left by previous research and to give a more detailed and accurate description.It will alsouse historical documents to find the original names of these items and to illustrate a general conceptof their usage on different occasions.The different categories of women’s wear will be described in the following order:①robes orcoats;②jackets;③waistcoats or vests;④skirts;⑤pants and leggings;⑥shoes and socks;⑦headdresses;and⑧others.Of every category,the textiles,decoration,cut,form,style,colourand motif will be discussed.The way in which these items were combined will also be discussed.The comparison between women’s wear and men’s wear,women’s and children’s informal andformal dress will be given.Here are some tentative conclusions.First,the Manchu and Han style coexisted and mixedwith each other and were worn by both Manchu and Han women.Second,the basic silhouettesand cuts were relatively stable and conventional,while the decorations and details(openings,fasten-ings,pleats,vents,collars and hemlines)were different.The former represented accepted socialstandards while the latter could be a matter of personal taste.Third,women’s wear in that periodwere highly stylized,miscellaneous,elaborate,detailed,multicolored and multi-thematic. 展开更多

Steel H13 was put in non toxic salt bath with addition of CeO 2 for co diffusion of sulfur, nitrogen and carbon and followed by oxidation treatment. The effect of rare earths on the improvement of wear resistance and high temperature oxidation resistance of steel H13 was studied using scanning electron microscope, energy dispersive spectrometry and X ray diffraction. The results show that compared to the surface treatment without rare earth addition, the treatment with addition of rare earths improves the wear resistance and high temperature resistance to oxidation of steel H13. Under the conditions of 30 N and 2 h, the wear weight loss was decreased by 40%, and the friction coefficient was reduced from 0 25 to 0 22; whereas for 150 N and 0 2 h, the wear weight loss was decreased by 24%, and the friction coefficient was reduced from 0 35 to 0 32. For the oxidation at 700 ℃ and 4 h, the rate of weight gain decreased to only about 1/30 of that without rare earths. 展开更多

Abelmoschus is a genus of about fifteen species belongs to the family Malvaceae. The herb, popularly known as Lady’s Finger or Okra (in English) is a nutritional source used for both medicinal and culinary purposes. The plant is widely distributed from Africa to Asia, Southern Europe, and America. This comprehensive account provides a botanical description of the plant, its phytochemical constituents and pharmacological activities focusing anti-diabetic, anti-oxidant, anti-adhesive, gastro-protective, hepatoprotective, and immunomodulating actions. Most of the pharmacological effects can be explained by the constituents like tannins, terpenoids, flavonoids and glycosides present in all plant parts. However, future efforts should concentrate more on in vitro and in vivo studies and also on clinical trials in order to confirm traditional wisdom in the light of a rational phytotherapy. The present review is an overview of phytochemistry and ethnopharmacological studies that support many of the traditional?ethnomedicinal uses of the plant. 展开更多

The present study deals with investigation relating to the influence of wear parameters like sliding speed, applied load and sliding distance on the dry sliding wear of aluminium metal matrix composites. The design of experiment approach was employed to acquire data in controlled way using Taguchi method. A Pin-on-disc apparatus was used to conduct the dry sliding wear test. An orthogonal array, signal-to-noise ratio and analysis of variance were employed to investigate the wear behavior of aluminium and it’s composite. The mathematical model was obtained to determine the wear rate of the aluminium and it’s composite. The confirmation tests were conducted to verify the experimental results. The incorporation of Be3Al2(SiO3)6 as reinforcement material in aluminium matrix material improves the tribological characteristics. 展开更多

Lady Chatterley’s Lover is David Herbert Lawrence’s last novel of elaborating sexual relationship in extramarital affairs.Since the novel was published in 1928,scholars have been studying it from various perspectives.Lawrence depicts intercourse between the two protagonists explicitly by actions,discourses and mental acts,and he once justified the publication of this book,which provides possibility and clues for probing his view of sex and sexual relationship through the novel.Staring from Mellors’discourses with Connie,the description of male characters,and the anima and animus archetypes in the novel,the paper analyzes Lawrence’s sexual theory and his advocacy for combination of body and soul based on the British society then and Lawrence’s own experience. 展开更多
