In many electronic applications, chemical etching process is used to manufacture the substrates. This method has been applied for long on quartz crystal blanks manufacturing for minor adjustments of the vibration frequencies. This paper pesents a way to implement an industrial chemical etching process specially dedicated for large thickness removals without damaging the blanks surface texture. ...

Methods Following a standardized physical exam using sterile gloves and a sterile stethoscope, bacterial contamination of the following regions were assessed using contact plates: stethoscope diaphragm, stethoscope tube, fingertips, thenar region, hypothenar region and back of physician’s dominant hand. Total aerobic colony count (ACC) were determined on digital photographs using a counting tool.

INTRODUCTION Food-borne infections and intoxications remain one of the most important public health issues globally, both in developing and in developed countries. Numbers of reported outbreaks of food-borne diseases and diseased people are constantly growing. For instance, a total of 320,000 of cases of food-borne diseases, caused by only 6 most prevalent bacterial pathogens (non-typhoidal Sal...

Background The Sediment Quality Objectives (SQO) indirect effects assessment determines whether sediments meet California’s narrative SQO for human health: Pollutants shall not be present in sediments at levels that will bioaccumulate in aquatic life to levels that are harmful to human health. This program determines whether sediment contamination at a site results in an unacceptable health ris...
