No full textNew meaning in traditional wedding dresses – Xiu He Fu and Long Feng Gua – in contemporary China / Li Yuling
No full textChinese traditional wedding dresses have a long history, they are auspicious symbols for Chinese women. Embroidered decorative and symbolic elements on wedding dresses, represent well wishes for marriage, such as lasting marriage, more sons, more happiness. Although the Western white wedding dress has crossed cultures and many modern Chinese women wear them on their wedding day, the traditional Chinese dresses have re-emerged at the end of the 20th and early 21st century.1 The Chinese traditional wedding dresses have recently become popular again in wedding ceremonies, especially the type of xiu he fu秀禾服 and long feng gua龙凤褂.2 However, this research argue that the traditional wedding dresses have changed in contemporary time, particularly the meaning of them for contemporary Chinese women are different. Because dresses in different situations will represent different identities. When the time, situation or context change, the representation also changes.
This study will investigate the new meaning found on these traditional wedding dresses. Iconological study of the symbols in history as well as the context of historical and contemporary traditional wedding dresses will be used to investigate the changes in Chinese gender and national identity. Much literatures record the images and context of symbolic patterns on Chinese folk dresses; also the symbolic meaning of embroidered patterns in the past have been recorded, for example, lotus/lian 莲 means purity. However, we do not have researches that specifically look at contemporary Chinese women's identities through the symbols on Chinese traditional wedding dresses. This research will study the embroidered decorations on contemporary traditional wedding dresses as more than superficial beautifying decorations, but as new symbolic representations of the contemporary Chinese women.
In a word, this research will relate the Chinese gender and national identity with representation of Chinese traditional wedding dresses in contemporary time. It is in order to analysis that the new meaning of Chinese traditional wedding dresses for women is to express their contemporary Chinese identity, this Chinese identity includes that “the Chinese” national identity and the gender identity of women being part of Chinese nation
2D fin field-effect transistors integrated with epitaxial high-k gate oxide
No full textPrecise integration of two-dimensional (2D) semiconductors and high-dielectric-constant (k) gate oxides into three-dimensional (3D) vertical-architecture arrays holds promise for developing ultrascaled transistors1–5, but has proved challenging. Here we report the epitaxial synthesis of vertically aligned arrays of 2D fin-oxide heterostructures, a new class of 3D architecture in which high-mobility 2D semiconductor fin Bi2O2Se and single-crystal high-k gate oxide Bi2SeO5 are epitaxially integrated. These 2D fin-oxide epitaxial heterostructures have atomically flat interfaces and ultrathin fin thickness down to one unit cell (1.2 nm), achieving wafer-scale, site-specific and high-density growth of mono-oriented arrays. The as-fabricated 2D fin field-effect transistors (FinFETs) based on Bi2O2Se/Bi2SeO5 epitaxial heterostructures exhibit high electron mobility (μ) up to 270 cm2 V−1 s−1, ultralow off-state current (IOFF) down to about 1 pA μm−1, high on/off current ratios (ION/IOFF) up to 108 and high on-state current (ION) up to 830 μA μm−1 at 400-nm channel length, which meet the low-power specifications projected by the International Roadmap for Devices and Systems (IRDS)6. The 2D fin-oxide epitaxial heterostructures open up new avenues for the further extension of Moore’s law. © 2023, The Author(s), under exclusive licence to Springer Nature Limited.11Nsciescopu
Comparison of Different Extraction Processes on the Physicochemical Properties, Nutritional Components and Antioxidant Ability of Xanthoceras sorbifolia Bunge Kernel Oil
No full textIn this study, we investigated and compared the oil yield, physicochemical properties, fatty acid composition, nutrient content, and antioxidant ability of Xanthoceras sorbifolia Bunge (X. sorbifolia) kernel oils obtained by cold-pressing (CP), hexane extraction (HE), aqueous enzymatic extraction (AEE), and supercritical fluid extraction (SFE). The results indicated that X. sorbifolia oil contained a high percentage of monounsaturated fatty acids (49.31–50.38%), especially oleic acid (30.73–30.98%) and nervonic acid (2.73–3.09%) and that the extraction methods had little effect on the composition and content of fatty acids. X. sorbifolia oil is an excellent source of nervonic acid. Additionally, the HE method resulted in the highest oil yield (98.04%), oxidation stability index (9.20 h), tocopherol content (530.15 mg/kg) and sterol content (2104.07 mg/kg). The DPPH scavenging activity rates of the oil produced by SFE was the highest. Considering the health and nutritional value of oils, HE is a promising method for X. sorbifolia oil processing. According to multiple linear regression analysis, the antioxidant capacity of the oil was negatively correlated with sterol and stearic acid content and positively correlated with linoleic acid, arachidic acid and polyunsaturated fatty acid content. This information is important for improving the nutritional value and industrial production of X. sorbifolia
Different generations, different face? A discursive approach to naturally occurring compliment responses in Chinese
No full textAdopting a discursive approach to politeness (see, for example, Mills 2011), this paper explores spontaneous naturally occurring compliment responses (CRs) in Chinese from a cross-generational perspective. It aims to extend our understanding of the dynamic nature of face and/or politeness in contemporary Chinese. 16 multiparty conversations among two generations of the Chinese in China’s mainland were audio recorded. Based on evidence provided by the participants in the follow-up interviews, my data analysis yielded two major results: (a) compliments, CRs and CR strategies are not as easily identifiable as previous studies claim; (b) considerable generational variation emerges in the use of CR strategies, viz. the older generation participants were more than twice as likely as the younger to reject a compliment while those in the younger group tended to use Acceptance much more readily. In the discussion, I show how, by using a methodology which emphasizes the interactants’ perceptions obtained through interviews, my study brings to light evidence that intention is not self-evident in performing compliments and CRs. Finding (a) indicates that my emic approach to data analysis provides a useful perspective on the complexity of the notion of intention in studies on speech acts (and perhaps beyond). Finding (b) appears to indicate that the two generations of the Chinese have diverged in their conceptualization of face and/or politeness perhaps due to differences in their early socialization before and after the launch of China’s reform. I also demonstrate how my methodology enables me to seek this generational variation
INVESTIGATION ON STATOR AND ROTOR VIBRATION CHARACTERISTICS OF TURBO-GENERATOR UNDER AIR GAP ECCENTRICITY FAULT
No full text This paper investigates the stator and the rotor vibration characteristics of turbo-generator under the air gap eccentricity fault. Firstly the air gap magnetic flux density of the fault is deduced, and the formula of the magnetic pull per unit area acting on the stator and the unbalanced magnetic pulls of x-axis and y-axis acting on the rotor are respectively gotten. Then the static eccentricity, the dynamic eccentricity and the mixed eccentricity are respectively studied to analyze the stator and the rotor vibration characteristics. Finally experiments are done on a SDF-9 non-salient fault simulating generator to verify the theoretical results. The investigation results of this paper will be beneficial to the air gap eccentricity fault diagnosis of turbo-generator. </jats:p
