The degeneration of mechanical properties is one of the main concerns in assessment of fire damaged pressure vessels. This study investigates the influence of fire exposure on mechanical properties of Q345R steel which is widely used for pressure vessels in China. Heat treatment with different temperatures and holding times was conducted to simulate various heat exposure conditions in fire event. Hardness testing, metallographic analysis and tensile tests were carried out to investigate the effects of fire exposure temperature and duration. The experimental results indicate that the inflection temperature for mechanical property degeneration of Q345R steel is 700 °C. The decline of hardness, yield and tensile strengths due to spheroidization become more obvious with increasing heat exposure duration. A linear correlation is indicated by fitting the tensile strength and hardness. For the assessment of fire damaged component, the mechanical properties of Q345R steel at room temperature can be determined combining on-situ field metallographic examination and hardness testing with.

HONG KONG, Dec. 5, 2016 /PRNewswire/ -- As it is commonly understood, to appear decent, people need apparel like horses need a saddle. Although some argue that one cannot judge a book by its cover, apparel today represents not only one's taste, but also one's attitude in life. When glancing at photo shoots released by various fashion media, you might be surprised that the vogue and glamor of fashionable clothes and accessories are no longer limited to models. Trendy and attractive outfits on common people also exhibit an eye-catching scene. China Will Become the Largest Apparel Market It might be shocking when certain numbers are checked. According to the prediction released by Statista, by 2025, the global market volume of apparel will amount to USD 2,100 billion (representing approximately RMB 13.7 trillion). In addition, China will become the largest apparel market in the world, with a market volume of USD 540 billion (representing approximately RMB 3.5 trillion). According to Statista's prediction, China will account for 25.6% of the entire global apparel market. Top Five Export Destinations for the Chinese Apparel Industry in 2015 Ranking by export value in 2015, the US, Japan, the UK, Germany, and the United Arab Emirates are the top five export destinations for the Chinese apparel industry. In 2015, the total export value of the Chinese apparel market was RMB 1,021 billion. The export value of the top five export destinations accounted for 44% of the total export amount of the entire industry. In recent years, the Chinese apparel industry has been confronted with quality issues. In addition, even some world-renowned luxury brands are frequently recalled due to the quality issues. In this August, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China issued a recall announcement for some imported luxury brand's Children's apparels, as their pH value and formaldehyde level exceeded China's mandatory standards. Countries in the European Union (EU) have always been a major export market for the Chinese apparel industry. From 2011 to 2015, its export value accounted for 24.4% of the total export value. EU stresses great importance to the quality and safety issue regarding apparel products. "Clothing, textiles, and fashion" is one of the product category under the Rapid Exchange of Information System (RAPEX) that is generating the most concern. According to the statistics available under the RAPEX, 329 reports in total were related to clothing, textiles, and fashion items, among which, 171 reports involved clothing, textiles, and fashion items from China as the country of origin. This report accounted for 52% of the total reported items. As to the clothing, textiles, and fashion items, the primary risk exposure as reported under the RAPEX refers to "injuries" and "strangulation", which has consecutively exceeded 60% of the risk exposure as reported over the last three years. Such risk exposure is commonly detected in such apparel as sportswear and bikinis for girls. Strings and functional cords attached to such apparel that fail to comply with the requirements may cause children to get caught in fences, automated escalators, and other equipment, which may further lead to their suffocation. To address such risk, European countries stipulate apparel items for children must be in compliance with the EN 14682 standard. TUV Rheinland is capable of assisting manufacturers in conducting stringent inspections and testing over apparel items in accordance with this standard to ensure that apparel items are free from such risk exposure as "injuries" and "strangulation". The "Chemical" risk exposure ranks second. It involves hexavalent chromium contained in leather products. Hexavalent chromium contains sensitive substances that may trigger allergic reactions. If apparel items contain prohibited Azo dyes, such items will blend with compounds released due to one's metabolism and cause reduction-oxidation following a prolonged contact with one's skin. In such case, aromatic amines, which are cancer-induced substances, will be generated. In 2013, cancer-induced aromatic amines were detected in a batch of winter school uniforms manufactured by a Shanghai-based fashion company, thus becoming a hotspot for "toxic school uniforms". This further drew attention from the community. To address such risk, TUV Rheinland, who also has rich experience in such inspections and testing, will be able to exercise stringent control over apparel items in accordance with the Regulation (EC) No 1907/2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), thereby eliminating the potential chemical risk involved in apparel. As a global leader in the testing, inspection and certification industry, TUV Rheinland's laboratories are accredited certified by Die Deutsche Akkreditierungsstelle GmbH (DAkkS) in Germany, China National Accreditation Service for Conformity Assessment (CNAS) in mainland China, and Hong Kong Laboratory Accreditation Scheme (HOKLAS) in Hong Kong, enabling it to provide the relevant testing and certification services to apparel items in accordance with the mandatory and recommended requirements under the international or national standard and provisions. TUV Rheinland has been providing testing and certification services to a list of reputable international brands in apparel, including Diesel, DKNY, NEXT, etc. With professional qualifications and experience, TUV Rheinland will assist manufacturers in ensuring the safety and quality of apparel items through the following procedures. If apparel contains zippers, buttons, rivets, sequins, or other decorative accessories, particular attention shall be paid to the sharp corners and edges of these small decorative parts. Small parts, including buttons, beads, decorative yarn balls, bows, and fine strings, will pose a potential safety threat to children under 36 months old. Such small parts attached to apparel must be reinforced to eliminate the potential risk of suffocation. Dark-colored apparel, as well as apparel items that contains a large area of dye patterns, must be avoided as much as possible, as such apparel might contain an excessive level of phthalates, which easily poses a threat to the immune system, the digestion system, and the endocrine system. Meanwhile, TUV Rheinland also recommends that consumers from time to time pay attention to the information published by third-party testing, inspection and certification bodies for purchasing safe apparel items.

In the overall landscape of risk management in China, enterprise legal risk management can be singled out as a prominent development in the recent years. This development reflects the dramatic changes to the domestic environment within which the Chinese companies operate and the progress the Chinese companies made when they interacted more closely with international partners. In this article we analyze the concepts, tools and the relative standards about legal risk management. We also look at the legal risk management in Chinese companies by studying a concrete case of implementation of legal risk management system in a large State Owned Enterprise. While doing that, we highlight some of the general features of legal risk management implementation of the Chinese market. © 2015 Taylor & Francis Group, London.

Bactrocera correcta is one of the most destructive pests of horticultural crops in tropical and subtropical regions. Despite the economic risk, the population genetics of this pest have remained relatively unexplored. This study explores population genetic structure and contemporary gene flow in B. correcta in Chinese Yunnan Province and attempts to place observed patterns within the broader geographical context of the species total range. Based on combined data from mtDNA cox1 sequences and 12 microsatellite loci obtained from 793 individuals located in 7 countries, overall genetic structuring was low. The expansion history of this species, including likely human-mediated dispersal, may have played a role in shaping the observed weak structure. The study suggested a close relationship between Yunnan Province and adjacent countries, with evidence for Western and/or Southern Yunnan as the invasive origin of B. correcta within Yunnan Province. The information gleaned from this analysis of gene flow and population structure has broad implications for quarantine, trade and management of this pest, especially in China where it is expanding northward. Future studies should concentrate effort on sampling South Asian populations, which would enable better inferences of the ancestral location of B. correcta and its invasion history into and throughout Asia.

The West Indian fruit fly, Anastrepha obliqua (Macquart), is one of the most important pests throughout the Americas. CLIMEX 3.0 and ArcGIS 9.3 were used to model the current and future potential geographical distribution of this pest. Under current climatic conditions, A. obliqua is predicted to be able to establish throughout much of the tropics and subtropics, including not only North and South America, where it has been reported, but also southern Asia, northeastern Australia and Sub-Saharan Africa. The main factors limiting the pest's range expansion may be cold stress. Climate change expands the potential distribution of A. obliqua poleward as cold stress boundaries recede, but the predicted distribution in northwestern Australia and northern parts of Sub-Saharan Africa will decrease because of heat stress. Considering the widely suitable range for A. obliqua globally and in China, enhanced quarantine and monitoring measures should be implemented in areas that are projected to be suitable for the establishment of the pest under current and future climatic conditions. © 2013 Institute of Zoology, Chinese Academy of Sciences.

Research and Markets has announced the addition of the "Dairy Products China News" report to their offering. On 4 September, the 5th Cross-Strait Fresh Milk Development Forum was held in Fuzhou City, Fujian Province. During this event, the "Circle of Friends" for the China Quality Milk Programme was jointly established by 20+ dairy companies (including New Hope Dairy, Changfu Dairy, Bright Dairy, Beijing Sanyuan, Huishan Dairy, Wondersun Dairy, NanJing Weigang Dairy, Kunming Xuelan Dairy, Jinan Jiabao Dairy, Henan Huahuaniu Group Dairy, Yantang Milk, Fengxing Milk, Jiangxi Sunshine, Guizhou Haoyiduo Dairy, Xuzhou Lujian Dairy, Tianyou Dairy). This aimed to promote the programme's implementation and speed the development of the fresh milk segment ("Circle of Friends" is an imitation of WeChat's function, "Moment", which is also known as "Circle of Friends".) For a long period take-up of the programme has been called for by the domestic dairy industry. However, some large dairy companies have held back from full implementation. The programme mainly consists of: Labelling products as "Quality Milk" Dairy farming technology upgrade Supervision of standardisation of processing The accreditation is mainly targeted at fresh milk, which should have characteristics such as "near to raw milk sources", "short-distance refrigerated transportation" and "instant consumption". Consumers are expected to easily see whether the milks are "quality" through the labelling. "The programme will help rebuild confidence in domestic milk products and ease the imbalance of profit distribution in the industry," commented a trade source. Ever since the melamine scandal, China's dairy market has endured periods of rapid price drops or increases. This year is "the hardest year for the domestic dairy business," stated Gao Hongbin, Director of the Dairy Association of China (DAC): "In March, 51% of companies made a loss. In H2, this proportion is still growing." There are two fundamental factors behind the flat domestic dairy market: According to the National Bureau of Statistics, local sales of liquid milk (fresh + UHT, including imports) stood at 27.39 million tonnes in 2015, up by 3.6% - this compared with averages of 5.1% in 2011-2015 and 11.1% in 2006-2010. On 16 August, the DAC issued the China Dairy Industry Quality Report (2016), produced with support from China's National Health and Family Planning Commission, General Administration of Quality Supervision, Inspection and Quarantine and the China Food and Drug Administration. In 2015, national milk production (incl. goat milk) reportedly hit 38.70 million tonnes, whilst consumption of dairy products was 29.58 million tonnes. According to the 2015 China Rural Statistical Yearbook, the country's dairy herd stood at 15.07 million head in the same year. - The threat posed by foreign dairy products: China imported 1.79 million tonnes of dairy products in 2015, equal to about 11 million tonnes of milk (based on 1:8 ratio between powders and raw milk); in January-June, imports of milk powder (incl. infant formula) hit 407,800 tonnes (= 3.26 million tonnes of raw milk), up by 18.6% YoY; liquid milk imports were up by 77.55% to 314,000 tonnes. "Developing the fresh milk segment is a key means of surviving the sluggish market, depending on stressing the original milk's quality," said Gao Hongbin, implying its greater nutritional properties compared with long-life milk. Many local processors recombine imported powder to produce UHT milk as the international price is nearly 1/2 the domestic one. According to statistics from the International Farm Comparison Network (IFCN), the theoretical world milk price was about RMB1.44/kg in May, compared with RMB3.46/kg from China's 10 leading milk producing regions. However, going from raw milk to powder and then to reconstituted milk means 2 high-temperature sterilisations which cause huge nutritional losses (local processing specialists cite 60% of active protein being lost in the initial spray-drying). According to the Notice to Enhance Administration on Liquid Milk Production and Sales (released by the General Office of the State Council in September 2005,implemented on October 15, 2005), if reconstituted milk is used for producing UHT milk, manufacturers should note this on the label, and make clear the proportion used. The Identification of Reconstituted Milk in Fresh Milk and UHT Milk issued in April also stresses increased inspection of reconstituted milk. However few local dairy products using reconstituted milk are declared as such on-pack, an issue which clearly needs tackling. This represents an opportunity for fresh milk. Practice of the quality milk programme is expected to push dairy processors to purchase higher quality raw milk, and dairy farmers to increase their efforts to produce such a product. "The price of raw milk will increase materially in early 2017," stated dairy analyst Song Liang; "We expect fresh dairy products including fresh milk, yoghurt and ice cream will grow also. It is necessary to encourage companies to develop fresh milk to make a turnaround." Taiwan provides a good example of an industry countering use of imported milk powder with fresh milk: "30 years ago, we started promoting labelling for quality milk, and focused on developing fresh milk. Now 98%+ of local farm milk is used for producing fresh milk," stated Shi Zongxiong, Honorary Director of the Dairy Association of Taiwan. In mainland China, this percentage is very low. According to the China Dairy Industry Quality Report (2016), fresh milk accounts for 10% of the liquid milk market compared with 80%+ in the US and Australia. "We are making a 5-year plan for the quality milk programme, a move intended to increase the consumption of quality dairy products (meaning fresh milk) to 30%, and to 90%+ within 10 years," claimed Wang Jiaqi, DAC's Vice Director. On 23 August, Dali announced to launch soymilk next year; 2 days later, Vitasoy released its new coconut juice "Vitakaka". In reality, many plant protein beverage manufacturers have launched many new products. All this is strong demonstration about the market potential. On 4 September, at the 5th Cross-Strait Fresh Milk Development Forum in Fujian, the "Circle of Friends" for the China Quality Milk Programme was established by 20+ dairy companies. On 30 August, the CNCA announced to enhance supervision on Australian fresh milk companies. It seems that the manufacturers are facing risk of being suspended for registration in China. On 24 August, Ausnutria announced the takeover of Australian company Nutrition Care, a notable step in its diversification. In H1, Yili grew both sales and net profit, whereas Mengniu recorded a fall in net profit, achieving just 1/3 of the figure posted by Yili. In the future, growth will be centre on the 3rd-/4th-tier cities, where both companies are already active. On 13 September, local milk tea manufacturer Xiangpiaopiao launched the first "pure milk pure tea" on the market, a move intended to transform itself into a "healthier" supplier. On 19 September, Beingmate announced it had received government approval for its establishment of an infant formula plant with Fonterra. This is expected to strengthen their partnership and help Beingmate deal with the changes brought about by the Chinese infant formula registration policy. In September, the price of raw milk continued an upward trend, thanks to the traditional sales peak and decreased milk supply. On 22 September, the ground-breaking ceremony for a 10,000 cow farm jointly constructed by Qianjin Animal Husbandry and Jule Group was held. In September, Bright Dairy, following the launch of premium-marketed "Momchilovtsi" yoghurt, started marketing another such yoghurt "Zhi Da". This differentiated product is positioned as healthy and snack yoghurt and is targeted at South China.

The gypsy moth, Lymantria dispar, is an important economic pest that causes large-scale damage to forests worldwide. Because of its important role in initiating and controlling insect behavior, olfaction-and olfaction-based pest management-has drawn increasing attention from entomologists. In this study, we identified the gene that encodes the olfactory receptor co-receptor (OrCo). Through amino acid sequence alignment, we found that LdisOrCo shares high identity with other OrCo proteins from different insect orders. Next, we performed RNA-interference (RNAi) to assess the role of OrCo in olfaction. Electroantennographic assays showed that after RNAi, the average value of males response to sex pheromones was 0.636 mV, significantly lower than that of the positive control (average = 1.472 mV). Females showed no response to sex pheromones before or after RNAi. Finally, quantitative PCR showed a strong decrease in the expression of OrCo after RNAi, by ~74% in males and by 23% in females relative to the positive controls. These results indicate that OrCo is not only critical to odor recognition, but it may also represent a new target for development of semiochemicals that can influence insect behavior.
