Background: Foods have been many changes from production to tables and continuous control is necessary to maintain food safety and supply foods with good quality. The aim of this study was to evaluate the quality of some foods with high consumption in Zanjan city during the 5 years from 2009 to 2013. Methods: In a case-control descriptive study with an annually control program during 5 years f...

Readers of the current issue will find something unfamiliar , perhaps tantalizing, perhaps unsettling. I am referring to the articles by Cha et al. (see " Ionic mechanisms and Ca 2+ dynamics... " and " Time-dependent changes in membrane excitability... "). The first of these articles is less exotic; it presents computer simulations of a model for bursting electrical activity in pancreatic  cel...

We are very grateful to Kirk Hamilton and Giovanni Ruta of the World Bank and Peter Klenow of Stanford for very helpful advice and for generously supplying important data for this project. We also thank Kenneth Chay, and T. N. Srinivasan for very helpful comments.

The timing and mechanism of the combination between South China Block (SCB) Indochina (IB) are controversial. Three ophiolitic mélange zones (Ailaoshan, Song Ma, Chay) have been proposed as suture within this collisional orogen. However, relationships among three corresponding tectonic belts unclear. In study, we present detailed structural data for belts. bulk architectures Ailaoshan, Chay cor...
