Every day nearly 900m litres of treated water were lost and 240 leaks had to be fixed.Over the past five years, though, Thames Water has replaced 1,300 miles of cast-iron Victorian mains, those most likely to break, with plastic ones, reducing leakage to 670m litres per day.
A numerical model was developed and validated to predict the performance of a plastic rotary regenerator considering leakage and adsorption.
When using the bags, make sure to wrap meat in a plastic bag to prevent leakage onto other foods, don't use them for anything -- gym clothes, baby bottles, etc. -- other than groceries, and store in a cool, dry space.
Line a cracked vase with a plastic bag to prevent leakage.
While waiting for your groceries to be bagged (or when bagging them yourself), ask that your chicken be wrapped in a plastic bag to prevent leakage that could cross contaminate other vegetables, fruit or meat you may have purchased.
Caps were secured to the vials with plastic electrical tape to prevent leakage under heating.
Immediately after the cuvette was closed with a plastic cap to prevent CO2 leakage, the reaction was performed at 30 °C.
In order to realize an absolute static metal sealing, the squeeze quantity on sealing surfaces must reach a critical value, which creates enough contact pressure and makes elastic-plastic deformation happen within the metal seal as well as enough plastic flow to block micro leakage paths to achieve the static metal seal [28], as shown in Figure 4.
Chemical spills, radiation leakage, broken mountaintops, plastic waste that will never decompose, a depleted ozone layer, a floating garbage dump in the Pacific Ocean the size of a continent -- all this, and so much more, are the result of normal life in the 21st century.
