Community is the foundation of public health: the present paper reports the approach and strategy for intervention on the dairy production community developed by the Italian project ALERT (***), which implements the transfer of technical innovation and technological know-how from public research. Starting from the local role of primary producers, North-South and South-South networking (***) is needed to share solutions for transnational problems like climatic change, contaminated agro-farming sites and food waste and losses in the era of food crisis. Based on risk analysis, science-society dialogue and global health, the main drivers of this experience of translational research are One Health, i.e. the web of inter-relationships among environment, farm animals and human health, and sustainable food safety (prevention actions on diet of young women, today, to protect next generation’s health) to increase population life expectancy in good health.

Aerobic catabolism of S. cerevisiae (cell respiration) is a rapid, cost-effective, and reproducible toxicological endpoint of the whole cells biosensor. To increase the signal intensity, a protocol for the immobilization and modification of the yeast cells is described. In particular, the enzymatic treatment of the immobilized yeast cells allows removing the cell wall and obtaining structurally modified cells namely spheroplasts. Both immobilization and exposure of sensitive cells like spheroplasts confirmed to improve the method’s sensitivity vs. the chemicals. The present paper reports the test of different chemicals (including Mercury and wood preservative like Tanalith) present in consumer products, performed both by sensor with intact and modified whole cells.

A central composite rotatable design and response surface methodology were used in order to investigate the individual and combined effects of the ethanol-to-oil ratio, H2SO4 concentration, temperature and time of reaction on the reduction of free fatty acid （FFA） in jatropha oil. A quadratic polynomial model relating the reaction variables with FFA reduction was developed, presenting a good coefficient of determination （R2= 0.893）. For reducing FFA to less than 1%, the optimal combination was found to be 0.62 v.v^-1 ethanol-to-oil ratio （14.9 v.v^-1 ethanol-to-FFA ratio）, 1.7% *** H2SO4 concentration, and 79 rain reaction time at a reaction temperature of 54℃. These results are of great relevance to maximize methyl esters formation by transesterification using an alkaline catalyst.

Split-Brain DNS是一种域名系统配置方式，它允许来自网络内部和外部的资源被正确地做名称解析。当你把边界路Eh器或防火墙配置成丢包（drop packet），而你的边界路由器或防火墙连接的网络试图发送信息给它自己的时候，你需要使用split-brain DNS。你可以利用新建区域向导来配置一个新的主DNS区域。
