B application at a rate of 600 ppm produced the highest values of seed yield/plant （g）, head diameter （cm）, number of seeds/head, weight of 1,000 seed （g）, percentage of oil （%） and oil yield/plant （g） of both cultivars. Seed yield/plant increased by 26.85% and 34.81% with increasing B concentration from 300 ppm and 600 ppm as compared to control plants, respectively. The results indicated that application of 300 ppm B resulted in an increase of palmitic, stearic and oleic acids as compared to the treatment with 600 ppm B and control plants. However, the linoleic acid increased gradually with increasing B up to 600 ppm. Such increases were estimated by 8.72% and 7.19% over the control plants or the treatment sprayed with 300 ppm B, respectively. The highest oleic and linoleic acids percentages （52.71% and 36.05%, respectively） were obtained from Sakha-53 cultivar with 300 ppm B foliar application, while the lowest lenolenic acid percentage （2.01%） was obtained at 600 ppm B. The highest content of gluatmine, isoleucine and arginine （9.61, 3.97 and 3.97 mg/100 g dry weight） was obtained from Sakha-53 cultivar, followed by Giza-102 at a rate of 600 ppm foliar application of B. It can be concluded that B plays a vital role for increasing the productivity and quality of sunflower plants, especially when grown under B deficient soil.展开更多

The period of ＂12th Five-Year Plan＂ is not only an important period for the development of oral cleansing products industry, but also the critical time to promote the strategy of fully promotion on the industry standardization. The oral cleansing products standard includes three products： oral care products, oral care appliances and the raw material of oral care products. Toothpaste, as an important product of the oral care products, the earliest toothpaste standard in China can be traced back to 1956, and it became the first national toothpaste draft standard until 1987： GB 8372-1987 ＂Toothpaste＂. The standard was officially approved to be carried out on March 1, 1988. The technical index of GB 8372-2008 includes： net content, quality of toothpaste, pH vaule, stability, superhard particle, soluble and free fluoride, total fluoride, arsenic, mercury, etc.展开更多

The most distinguishing characteristic of drug abuse in ｜apart is that use of stimulants, mostly methamphetamine, accounts for over 80% of the arrests. Abuse of a stimulant called Philopon was widespread after the Second World War in ]apan, but the situation was dramatically improved after 1954 because the Japanese government enacted the Stimulant Control Act and restructured the police system and Japanese society recovered from post-war unrest. The situation of drug abuse in Japan has become less serious compared to the past and to the situation in many other countries, because we are taking comprehensive and nationwide measures, including proactive disclosure of the situation, control, drug abuse prevention class, and introduction of partial suspension of sentence. On the other hand, as in many countries, the rapid spread of new psychoactive substances （NPS） in recent years became a serious social issue. The situation of NPS has been rapidly improving due to comprehensive and government-wide measures, but the means of acquisition is quickly shifting to the Internet. It is necessary to strengthen cyber patrol.展开更多
