We clarified that photo-irradiation of young green barley from three different light sources, natural light, 100% red light-emitting diodes (R-LEDs), and a mixture of 90% red-LEDs + 10% blue-LEDs (RB-LEDs), had significantly different results in growth degree (weight and height) and in components of young green barley. Barley that has sprouted for 15 days after germination did not show any apparent difference in height in response to irradiation by the three tested light sources, but by the 20th day of sprouting the height showed a positive effect by R-LEDs irradiation. By 15 days of sprouting the barley had achieved the heaviest weight by natural light irradiation, while the barley irradiated by R-LEDs had made remarkable progress at 20 days of sprouting. On the other hand, the irradiation by RB-LEDs showed a suppressive tendency after 15 days or more. The amino acid content, as indicated by dry weight conversion, was greatest in the barley irradiated by RB-LEDs, followed by R-LEDs, and natural light, which showed that LEDs irradiation is effective. In addition, four cyanogenic glucosides were isolated, identified, and quantified, as they are components frequently assessed in barley research. With regard to vitamin E, R-LEDs irradiation increased γ-tocopherol. Our results indicate that irradiation by LEDs would be effective for the enhancement of the functionality of young green barley.

Aim: To clarify the factors associated with reported dietary fat intake by Japanese male children. Methods: This study is based on the data of a nationally representative cross-sectional study in Japan. Three hundred and seventy-seven male children (age, 6 - 11 years) whose households were sampled in the 1995 Comprehensive Survey of Living Conditions of the People on Health and Welfare, and the 1995 National Nutrition Survey and whose parents were identified through record linkage between the 2 survey data sets were enrolled. Results: The final dataset in this study consisted of 377 boys with 329 of their parents. Fifty-two boys were found to be overweight (13.8%). The reported dietary fat intake was higher among the overweight boys than among the non-overweight boys. Maternal obesity was significantly associated with obesity in male children. Boys who frequently consumed foods from the “fats and lipids” group and the “meat” groups, and children from nuclear families rather than 3- generation families reported high dietary fat intake. In addition, parental fat intake was also significantly associated with fat intake of male children. Conclusions: Child and parental dietary habits along with the household status should be considered when implementing nutritional education programmes to control dietary fat intake and reduce the obesity risks of male children.

在超导材料开发的同时研究人员一直在注意提高超导磁体的质量。1987年卡尔斯鲁厄大会公布的一种含有Ti/Nb3Sn基合金的磁体,其最高记录的磁通密度迄今为20.15泰斯拉（T）。然而高磁场的产生需要低温条件。一种新近发现（1986）的氧化物基高温超导体虽然达到高临界温度（Tc）,但仍应该作进一步开发,使之成为产生高磁场的超导磁体。对超高磁场的研究也是对极端领域如超高温、超低温、超高压和超高真空领域的研究。借助新科技考察各种材料（金属、半导体、活体、大分子、液晶等）和原子、分子、原子团以及离子,可望导致新材料的发现和/或新现象的开发。在高磁场中,物质可能显示出独特

我们已试制出一种感应加热用的电流馈电高频逆变器,在98％的高效率下其输出功率很大。这种逆变器电路是单相全桥式逆变器,侵用了四个额定值为300A、1200V的SI晶闸管。由于所使用的晶闸管没有反向阴断特性,所以使用串联二极管和小功率反向并联二极管制出了桥接电路。在控制系统中,变换器部分控制输出功率,而逆变器部分控制工作相位。在整个工作相位控制期间,在关断状态下,通过域小开关损耗和抑制SI品闸管的浪涌电压,得到了高效无缓冲的转换。

为降低直接喷射火花点燃式(DISI)发动机冷起动期间的HC排放进行了试验研究,目的是用分析方法定量研究燃油特性,并提出一些实际技术以减少气缸湿壁燃油量和发动机排出的HC排放。与MPI(多点进气道燃油喷射)发动机相比,DISI发动机在冷起动过程中所需的燃油量较少,因为不会产生进气道湿壁现象。另一方面,大量的气缸湿壁燃油导致发动机排出HC。喷油定时、喷射燃油的雾化和蒸发会影响气缸湿壁燃油量。尤其是加热的燃油喷射会获得好的结果。总之,与MPI发动机相比,DISI发动机冷起动期间排出的HC排放降低了。

Journal of Diabetes Mellitus 2016年第1期6卷 10-15页

Background: The glycated albumin (GA) to HbA1c ratio (GA/HbA1c ratio) has been reported to reflect postprandial hyperglycemia. Carbohydrate is the primary dietary macronutrient that causes postprandial hyperglycemia. Thus, we investigated whether carbohydrate intake was associated with the GA/HbA1c ratio in patients with type 2 diabetes. Methods: Daily energy intake and carbohydrate intake were estimated in twenty-two patients with type 2 diabetes who received no pharmacological therapy (18 men and 4 women, age 53 ± 11 years old). The energy index and the carbohydrate index were defined as the ratio of daily energy intake to body weight and daily carbohydrate intake to body weight, respectively. Results: The energy index was significantly correlated with the GA/HbA1c ratio (r = 0.451, p = 0.035), but not with fasting plasma glucose (FPG), HbA1c and GA. The carbohydrate index was significantly correlated with GA (r = 0.461, p = 0.031) and the GA/HbA1c ratio (r = 0.554, p = 0.007), but not with FPG and HbA1c. Multivariate analysis revealed that the carbohydrate index was independently associated with the GA/HbA1c ratio (β = 0.397, p = 0.046). Conclusions: The carbohydrate index was significantly correlated with GA and the GA/HbA1c ratio in the patients with type 2 diabetes. These results suggest that carbohydrate intake may be associated with the GA/HbA1c ratio through postprandial hyperglycemia.
