Although these assays have an irreversible response, time-dependent changes in sweat composition can be captured by using fluidic designs that enable time-sequential sampling (chrono-sampling) of sweat using passive valve constructs (40, 45). The example in fig. S8A uses collections of CBVs to enable sequential filling of a series of independent microreservoirs, each pre-impregnated with a colorimetric reagent. Briefly, CBV #1 has the smallest bursting pressure (BP) due to its wide channel width (200 μm) and small diverging outlet angle (21°). CBV #2 has the second smallest BP due to its larger diverging angle (90°) with a width that is the same as that of CBV #1. When sweat encounters the intersection between CBV #1 and CBV #2, it flows through CBV #1 due to its smaller BP. After filling the chamber, the sweat flows to CBV #2 because CBV #3 has the highest BP due to its small width (50 μm). The sweat gland generates fluidic pressure through osmotic effects associated with the concentration difference between sweat and plasma. The microfluidic platform contains CBVs specially designed to open within the physiological range of sweat pressures. Hence, the pressure generated by the glands themselves is sufficient to open each chamber (39, 45). Using this process, the device collects and stores sweat in time sequence in separate chambers. The left and right sides of the device provide chrono-sampling analysis of pH and chloride, respectively.

Fstoppers readers are from all over the world. When you recommend a insurance, maybe you should explain it's for US, UK, Australian etc readers only.

It's not uncommon to look in a fridge and see a few eggs hanging out in the door. You need to fill the egg rack, right? Wrong said Kerkenbush. When you store eggs in the door, you expose them to sudden temperature changes each time the door opens and closes, which may cause them to go bad faster.

A: People who are willing can share what they know. My organization does a quarterly mending circle where three women teach people how to mend. When we belonged to a CSA (community supported agriculture), we helped on the farm we supported and learned how to grow and harvest. Now we plant our own garlic. One of my neighbors taught me how to make jam. I became a Master Gardener and now I help people start gardens. One past roommate taught us how to repair a bicycle. Young parents can create a child-care exchange or maybe share pet care. There’s a book I use when I teach, titled “The Sharing Solution: How to Save Money, Simplify Your Life & Build Community,” by Janelle Orsi and Emily Doskow (Nolo Press). It’s a super wonderful resource for people looking for ways to share.

I would have asked the same thing before I did a little cost evaluation. At our home, we eat a lot of deli-style turkey — $6.59 per pound at my local Costco. The same brand roast turkey breast unsliced is $3.99 per pound. The exact same thing!

Due to imminent health hazards observed during this inspection, the establishment was been a Cease Operations Order and must discontinue food operations immediately. The establishment could not operate for a minimum of 48 hours. Inspected Jan. 14.

I just rub it over the screen, and it gathers the lint. I tap the brush on the edge of a trash can to remove the lint. The brush can be used over and over again. — Sue H., Falls Church, Va.

In the summertime, Mark DenUyl of Marysville loads thousands of pounds of busted-up concrete into his trailer and hauls it behind his Ford F-350 pickup, which is filled with construction equipment while driving over pothole-filled roads for weeks at a time in temperatures exceeding 90 degrees.

Not only does it allow you to slow cook your food right at your desk, but the Crock-Pot small slow cooker can hold up to 20 ounces which makes it the ideal size for lunches, dips, and more. The spill-proof lid and sturdy handle makes transporting this cooker easy, and the exterior won't get hot while it's operating.

Since I don't contribute to every organization, what can be done with the unused stamps? Can I cut them off and use them for personal mail? — B.M. in Virginia
