17. Pests  Insects and bugs may be a source of great annoyance to budding gardeners, but don’t be too liberal with toxic pesticides – so if it is necessary to treat plants or growing vegetable crops, try to use an organic alternative.

The second set of studies focuses on comparing temporal variations in glucose and lactate levels in blood and sweat due to consumption of food and engagement in physical exercise. Here, the subjects wear the device over the course of a day and perform a series of periodic exercise sessions (15 to 20 min) on a stationary bike. The subjects begin the study in a fasting state and cycle 30 min before and 30 and 90 min after consuming breakfast and lunch. Blood tests use protocols similar to those for the first set of studies. Figure 7 (A and B) shows data acquired for subject #1 during these long-term sweat monitoring studies, while figs. S10 and S11 illustrate data for additional subjects. Photographs of the device at different stages of the study, as shown in Fig. 7A and fig. S10, indicate robust adhesion to the skin throughout. Analysis reveals that the blood glucose and lactate levels after each session follow trends that are qualitatively similar to those of data measured in sweat using the skin-interfaced devices. The sweat glucose values lag behind those acquired from blood tests by ~30 to 60 min, while a much smaller time lag exists between blood lactate and sweat lactate. Similar time lags appear in studies of various noninvasive (26) and minimally invasive (50) chemical sensors and can be attributed to the complex biological pathways through which blood constituents reach other biofluids. Analysis of the human trial data reported in Fig. 7B and fig. S11 at specific time points yields correlations between corresponding analyte concentrations in sweat and in blood. The comparison involves blood values for glucose and lactate just before and after each 15- to 20-min cycling session, respectively (fig. S12). The data reveal a relationship between concentrations of these two metabolites in sweat and blood. The results suggest some potential for using sweat sensors as a noninvasive means for tracking blood glucose and lactate concentrations. Error bars for the data from the sweat sensors represent the SDs for the last 1 min of data recording (maximum SD of 2.5 and 3.9 mV for lactate and glucose sensors, respectively). Error bars for the blood meters correspond to data provided by the respective vendors (RSD of 5% and SD of 0.12 mM for glucose and lactate strips, respectively). Contamination caused by residual analytes from previous sweating sessions may explain the outliers (marked in red circles). Modifying the microfluidic designs to optimize fluid flow and purging in the reaction chambers is a potential strategy to eliminate these outliers. In addition, replacing the microfluidics more frequently remains a reliable and viable solution due to the convenient detachability and low-cost nature of the microfluidic component.

What do you do with leftovers? How do you store dry food? Do you prepare your meals for the week ahead?

Extruded products most commonly require a dryer. “When a product is made on an extruder there is usually moisture added during this cooking step in the form of steam or water to get the correct product appearance and cook level,” explains Galen Rokey, process technology director, Wenger Manufacturing, Sabetha, Kansas. “This moisture must then be removed for product shelf life. Typical extruded pet foods may contain 20% to 30% moisture prior to drying. Conveyor speeds within the dryer allow the proper bed depth and retention time. Drying temperatures are another operating parameter needed to reach a product moisture level between 6% and 8% as the product leaves the dryer.”

Once the plastic is off, try to cut off the remaining residue with a razor blade. You can also sand it off, using fine sandpaper and a sanding block, but this almost guarantees that you will need to refinish the top of the cabinet.

An important step in the drug approval process, stability testing assesses how the quality of a drug substance or drug product (including its packaging) varies with time under the influence of environmental factors, including temperature, humidity and light. The process determines whether any physical, chemical or microbiological changes affect the efficiency and integrity of the final product, thereby ensuring that a pharmaceutical product is safe and effective, irrespective of where in the world it will be supplied. Moreover, stability testing establishes the shelf life and recommended storage conditions of a finished pharmaceutical product and the retest periods for a drug substance.

In the cold light of morning, surveying my trolleyload of folly, several things strike me. I don’t own a tin-opener. We don’t have the space to store everything (or more accurately, anything). And I forgot the cat food. The cat eyes me, hungrily.
