冬天,寒风凛冽,冰雪交融,大自然露出了一副冷酷的面容。此时,适当食用火锅,不仅可用火锅“火热”之气,驱散冬日的“阴冷”,营造一个“热烈”的氛围,而且还能有效补充人体需要的能量和营养,增强免疫力,抵御严寒,顺利过冬。其实,火锅不光在天寒地冻的冬季,而是一年四季都可食用,在养生方面也有“天时”的讲究。  相似文献

冬季,天气寒冷,冷邪袭人,阳光少见,使老人的身体发生了较大的变化。这种变化比其它季节更加明显,老年人的抵抗力比较弱,各种疾病容易发生。因此在老年人的饮食安排上,要适宜这种变化进行调理。传统医学认为,冬季万物收藏,由于北风凛冽,大地封冻,老年人中的阳气偏弱,阴寒日盛,极易刺激身体,使抵抗力日益降  相似文献

过去5年来,在英国生儿育女的开销增长大幅提高了33%。根据英国最大的互助组织Liverpool Victoria出版的调查报告.如今,一个典型的家庭平均要花费186,032英镑才能将一个孩子从出生抚养到21岁(每年8,859英镑,合12,000欧元或17,600美元)。目前为止,最大一笔花销是托儿费。平均每个家庭在保姆、托儿所和课后照管方面支出50,538英镑(合68,500欧元或100,000美元),而教育经费则紧随其后,列第二位,平均为47,310英镑。186,000英镑能买到:位于迪拜的一间豪华单人公寓;一辆1925劳斯莱斯古董车或者一艘12米长,6个船舱的豪华油艇。同时,该组织还预测,从现在起至2012年,育儿开支可能进一步提高42%,达到惊人的265,577英镑,即每年要花12,500英镑(合17,000欧元,25,000美元)。  相似文献

Embroidered shoes have a long history. They were popular in the Ming and Qing Dynasties and are still popular in the Republic of China. They are traditional folk clothing accessories in Jiangnan area. The folk embroidered shoes in modern Jiangnan have great regional characteristics in shape technology and color and are rich in profound cultural connotation. They are handicrafts that perfectly combine traditional costumes and embroidery technology reflecting the unique charm of the costumes in the water town of Jiangnan. At present the researches on embroidered shoes in Jiangnan area are mainly analyzed from the perspective of manufacturing technology artistic characteristics and cultural connotation and rarely expounds its aesthetic characteristics and influencing factors from the perspective of color. Therefore the research on the color of modern Jiangnan folk embroidered shoes can restore the beauty of regional culture and help to carry forward and inherit Chinese traditional clothing culture. This paper made physical color measurement quantitative and qualitative statistics on the color of modern Jiangnan folk embroidered shoes which were collected in the Folk Costume Museum of Jiangnan University. It summarized the color characteristics of Jiangnan folk embroidered shoes analyzed the color aesthetics from three angles color layout color composition form and color implementation technology and explored the influence factors of the color formation of modern Jiangnan folk embroidered shoes from four aspects natural environment history and culture ideological belief and living customs. The research shows that the color of folk embroidered shoes in modern Jiangnan has obvious regional characteristics. Most of the main colors are simple and elegant mostly black navy blue and blue and decorated with red blue yellow and green with high saturation and high brightness. They form a color combination of "great unity and small contrast". The overall patterns of embroidered shoes are full of rhythm which can reflect the interest of the material and spiritual life of the Han nationality and contain profound cultural connotation. Its exquisite embroidery technology also enhanced the visual impact of embroidered shoes and the aesthetic value of patterns. Modern Jiangnan folk embroidered shoes have harmonious color proportion unique form and exquisite implementation technology. The local regional environment has a certain impact on the color composition of embroidered shoes. The humid and rainy climate the realistic and pragmatic Wu cultural concept the fresh and inaction color concept and the living customs of rice farming create the simple and elegant color image of Jiangnan folk costumes and highlight the gentle and beautiful image of Jiangnan women. This paper payed attention to the combination of empirical research and mathematical statistics excavated the influence of regional environment on the color of folk embroidered shoes in modern Jiangnan integrated art science and geography to explore the regional characteristics of costume color. In the future research we can further explore the age and occupation of the people wearing embroidered shoes in Jiangnan so as to make the research content more perfect. © 2022 China Silk Association.

The European Commission's, Quality of Life Research Programme, Key Action 1—Health, Food & Nutrition is mission-oriented and aims, amongst other things, at providing a healthy, safe and high-quality food supply leading to reinforced consumer confidence in the safety of European food. Its objectives also include the enhancing of the competitiveness of the European food supply. Key Action 1 is currently supporting a number of different types of European collaborative projects in the area of risk analysis. The objectives of these projects range from the development and validation of prevention strategies including the reduction of consumers risks; development and validation of new modelling approaches; harmonization of risk assessment principles, methodologies, and terminology; standardization of methods and systems used for the safety evaluation of transgenic food; providing of tools for the evaluation of human viral contamination of shellfish and quality control; new methodologies for assessing the potential of unintended effects of genetically modified (genetically modified) foods; development of a risk assessment model for Cryptosporidium parvum related to the food and water industries; to the development of a communication platform for genetically modified organism, producers, retailers, regulatory authorities and consumer groups to improve safety assessment procedures, risk management strategies and risk communication; development and validation of new methods for safety testing of transgenic food; evaluation of the safety and efficacy of iron supplementation in pregnant women; evaluation of the potential cancer-preventing activity of pro- and pre-biotic ('synbiotic') combinations in human volunteers. An overview of these projects is presented here.  相似文献

An investigation on the transformation paths of trehalose polymorphs and the interplay of water molecules is presented with the aim of underlining the role of trehalose structural and dynamic functions in the “protection” of biosystems and living organisms. To this end, physico-chemical studies have been carried out on water–trehalose interactions and on the structure and stability of the several forms, from the solution to the solid state (either amorphous or crystalline). In this paper the relevant results are critically presented and discussed with particular reference to most recent findings. The dehydration process performed under different confined conditions and controlled scan rates provides a dynamic phase diagram as a function of the time-scales of trehalose transformations and water effusion. A careful analysis of these data and of the stability of the glassy state in the presence of water evidences the reversibility of some trehalose transitions under the same conditions of natural processes of slow heating and controlled evaporation rate. This observation points at the hypothesis of the occurrence of these reversible paths at the basis of the bioprotection process.  相似文献

Quality of coffee is a complex trait and is influenced by physical and sensory parameters. A complex succession of transformations during the processing of seeds to roasted coffee will inevitably influence the in-cup attributes of coffee. Germination and fermentation of the beans are two bioprocesses that take place during post-harvest treatment, and may lead to significant modifications of coffee attributes. The aim of this review is to address the current knowledge of dynamics of these two processes and their significance for bean modifications and coffee quality. The first part of this review gives an overview of coffee germination and its influence on coffee chemistry and quality. The germination process initiates while these non-orthodox seeds are still inside the cherry. This process is asynchronous and the evolution of germination depends on how the beans are processed. A range of metabolic reactions takes place during germination and can influence the carbohydrate, protein, and lipid composition of the beans. The second part of this review focuses on the microbiota associated with the beans during post-harvesting, exploring its effects on coffee quality and safety. The microbiota associated with the coffee cherries and beans comprise several bacterial, yeast, and fungal species and affects the processing from cherries to coffee beans. Indigenous bacteria and yeasts play a role in the degradation of pulp/mucilage, and their metabolism can affect the sensory attributes of coffee. On the other hand, the fungal population occurring during post-harvest and storage negatively affects coffee quality, especially regarding spoilage, off-tastes, and mycotoxin production.  相似文献
