Awarded a UK patent, Senior’s PURe® range of energy-efficient aluminium windows and doors is the first on the UK market to benefit from an enhanced thermal barrier manufactured from expanded polyurethane foam (PUR). Traditionally used in cladding and insulation products, the innovative use of PUR as a thermal barrier in windows and doors gives the PURe ® range the potential to achieve U-values as low as 0.71W/m2 K when calculated as a commercial CEN standard window and 0.93W/m2 K when calculated as a CEN standard door. Shampoo, lotion, toner, face cream and fluoride toothpaste - just a few of the many products which we use daily, and which may have been tested on animals. Thousands of services flood the cosmetics aisle every year. For most of these products, animal testing was used at some point in its research and development. Though animal testing in research and drug development still remains common practice, even scientists now agree that alternatives to animal testing can and may help the non-public care and cosmetics industry. Wondering the other ways exist to test products as opposed to animal testing? Alternative methods have been cheaper, safer and supply faster results. Food preservation involves treating and handling food with the idea to greatly slow or stop spoilage that caused or accelerated by micro-organisms. Preservation normally involves preventing the development of fungi, bacteria along with other micro-organisms, along with the oxidation of fats which the cause rancidity. However, many ways of preservation actually use benign fungi, yeasts or bacteria to preserve food and add specific qualities, by way of example wines or cheeses. It may also include processes which inhibit aging and discoloration that occur during cooking, much like the enzymatic browning (oxidation) in apples when they are cut. Some food has to be sealed after treatment to avoid recontamination with microbes while others, including drying, mean food can be stored without special containment. There are many methods of preserving food including freezing, freeze drying, spray drying, food irradiation, sugar crystallization, adding preservatives, preserving in syrup, canning an d vacuum-packing.
