Together with an additional, external temperature sensor, the EE1950 allows for calculation of the relative humidity. It is therefore a solution for climatic chamber control.

If we can’t agree on a solution to Brexit all we can do is brace ourselves for the worst. As the Government readies the country for food shortages and a new cookbook uses stockpiled goods, Samuel Fishwick joins the preppers

“You’d be surprised by how much isn’t 100 per cent made here,” says Jo Elgarf, the admirable south London mother who helps run the 48% Preppers group (one of her four-year-old twins, Nora, has a rare brain condition called polymicrogyria, and she’s understandably concerned about medical supplies in the event of a no-deal Brexit). “You could have a pork pie made 95 per cent here, but then the gelatin comes from Europe.” Another friend, with a shady contact in the dairy world, warns me that 50 per cent of Britain’s yoghurt is produced outside the UK. It’s an apocryphal apocalypse, but one I am determined to prepare for. 

Lightning was the main electromagnetic presence in the Earth's atmosphere long before the invention of electricity. There are some 2,000 thunderstorms active at any given time, so humans and other organisms have been bathed ...

Fray Bentos, trusted “since 1888”, seems reassuringly indestructible. I buy 10 of their tinned pies. Powdered milk, three-kilo bags of fusilli pasta, 20 cans of tuna, Danish ham and an absurd volume of tinned macaroni cheese are piled into the shopping cart. 

Mouse droppings were found throughout the facility including on the surge protector in the food prep area and shelving throughout the food prep and storage areas; eggs were separated and repacked into sets of two, the food facility may not rework, repack or transfer shell eggs from their original cartons or containers; the food facility person in charge was not able to provide documentation that kimchi products are from an approved source; packaged kimchi, frozen raw chicken, frozen raw shrimp, pre-cooked frozen foods including chicken, deli meat, and sausages, candies, fruit cups, and other snacks were not properly labeled with the name of the product, ingredient statement, net weight, and distributed by statement; the door tracks, interior, and exterior surfaces of the deli display case, prep unit, and walk-in cooler were not clean; the slicer had an accumulation of food residue on the food contact surfaces and was not being disassembled, washed, rinsed and sanitized at least every four hours; tongs for rolls in the retail area were not protected from contamination; newspaper was lining the containers where are apples stored; cardboard boxes and lining were used in the retail area for storing onions and potatoes and on shelving.

What happens to the clothes when we’re finished wearing them? We put them in an old drawstring sleeping bag sack that takes up little space when it’s empty and expands nicely to hold dirty clothes for four. When the large sack is full, it’s time to do laundry.

The first part of the actual process is the screen printing of the solder. This thick goo is printed onto the myriad contact points of each bare PCB for the subsequent components to be attached to. Then my favourite machine ever starts its job.

Figure 6 (C to H) shows a device after cycling, along with a summary of data acquired from the lactate and glucose sensors for subjects #1 and #2, respectively. For both subjects, the respective sensors produce voltage signals that yield corresponding concentrations based on calibration plots obtained at ~30°C (usual sweat temperature) (39). Analyte concentrations reported in these studies are consistent with previously published studies (12, 20) and with average concentration values in sweat [14 mM lactate, 170 μM glucose, 23 mM chloride (pH 5.5)] (38). Image analysis of Fig. 6 (C and F) reveals that the concentration of chloride is 62 ± 5 mM (subject #1; chamber #1), 36 ± 5 mM (subject #1; chamber #2), and 34 ± 2 mM (subject #1; chamber #1); the pH is 6.3 ± 0.05 (subject #1; chamber #1), 6.2 ± 0.03 (subject #1; chamber #2), and 6.4 ± 0.1 (subject #2; chamber #1); and the sweat rate is ~0.52 μl/min (subject #1) and ~0.88 μl/min (subject #2). Separate analyses using conventional techniques such as commercial benchtop chloridometry, pH analysis, and high-resolution nuclear magnetic resonance (NMR) spectroscopy provide points of comparison. These methods are widely used analytical chemistry approaches in sweat studies (48, 49). Figure S8C illustrates a typical NMR spectrum. Table S2 summarizes the results. In all cases, measurements from the device correlate well with those using conventional techniques. The data reveal that NMR measurements, however, consistently overestimate the sweat glucose and lactate values by approximately a factor of 2 when compared to corresponding data acquired from the device. The differences could arise from a combined effect of comparing real-time data acquired from our sensor to time and spatially averaged sample concentration measured by NMR and partial evaporation of sweat during collection and changes in measured concentrations due to steps involved in lyophilization and redistribution of the solute in deuterium oxide for NMR analysis. The sample collection and analysis for conventional methods are independent of the sensor application and subsequent data acquisition. Another set of human trials (six males and two females; age, 18 to 45 years) involves analysis of chloride and performing a cycling session (15 to 20 min) while simultaneously collecting sweat samples for high-performance liquid chromatography (HPLC) analysis. Figure S9 shows a linear correlation between the data acquired from the colorimetric chloride assay with the sweat chloride concentrations acquired from HPLC, thus illustrating good performance of the colorimetric chloride assay for sweat analysis.

Placing food on a rooftop, hanging it on a line, or making an elevated drying rack like the Native Americans used to do will solve some of these problems. It works, it’s just not the most convenient, efficient, secure or sanitary way to dry food. And the quality of the food may suffer if drying times are prolonged or weather changes.
