Women and Asians were more likely to have food allergies and intolerances than other groups, the study found.

Beware of the Stock. Blue Apron, the meal-kit delivery company that wants to go public, serves up delicious meals and tantalizing sales growth. But look closely at the ingredients. New-customer acquisition costs are surging, customers are ordering fewer meals, and competitors abound. Like Groupon before it, Blue Apron is a case where the product is fine but the stock […] Written by roberthans Saving Bookmark this article Bookmarked Blog Feeding Young Minds: The Importance of School Lunches Harding Senior High, a public school in St. Paul, Minn., has long been known as a 90-90-90 school: 90 percent of students are minorities, nearly 90 percent come from poor or struggling families and, until recently, 90 percent graduate (now about 80 percent) to go on to college or a career.

We like to think of them as rather idealized voltage-controlled switches: you use a microcontroller pin to apply a bit of voltage to the gate and current flows freely through the channel. What could be better? The details, of course, paint a different picture. When we are working in […] Written by roberthans Saving Bookmark this article Bookmarked ICs such as the BCR401U provide high-quality control of LEDs for applications that require something better than the typical series-resistor arrangement. We all know that you can drive an LED with nothing more than a voltage source and a series resistor. But this is not the optimal approach. I won’t go into all the details because we already have an article that covers this topic. Here’s the abbreviated version: Current vs. Voltage The critical parameter […] Written by roberthans Saving Bookmark this article Bookmarked Better Insight into DSP: Learning about Convolution The world is increasingly streaming with electronic gadgets, a few for necessity but most for luxury. Irrespective of the category to which they fall-into, we can notice the basic fact that all of them make use of ‘signals’ to accomplish their tasks. Now, is it just enough to have signals? No, absolutely not.

Thermistors are available in two types: PTC (positive temperature coefficient) and NTC (negative temperature coefficient). The resistance of a PTC thermistor increases as the temperature increases. In contrast, the resistance of an NTC thermistor […] Written by roberthans Saving Bookmark this article Bookmarked Sex may be key to a happy marriage, study finds What is the recipe for a happy marriage? According to a new study, sex is a key ingredient. Researchers have found that sexual intercourse produces an “afterglow” that lasts for 2 days. What is more, this afterglow may boost long-term relationship satisfaction. Lead author Andrea Meltzer, of Florida State University, and colleagues recently reported their […] Written by roberthans Saving Bookmark this article Bookmarked Natural cannabinoid found to play key role in anxiety Stress-related mood and anxiety disorders affect millions of people in the United States. A new study examines the neurobiology behind these illnesses and finds that controlling a molecule that activates cannabinoid receptors can reduce the symptoms of anxiety.
