The estimation of the laundry unbalance and inertia is fundamental in washing machine applications. On one hand, management play a pivotal role reducing mechanical stress noise during spinning phase. other inertia’s estimation, performed at beginning cycle, allows for determination proper amounts water detergent, temperature, tumbling time. In this way, good performance obtained, avoiding waste...

Penicillium expansum produces large amounts of lipase, which is widely used in laundry detergent and leather industry. We isolated the glyceraldehyde-3-phosphate dehydrogenase gene (PeGPD) from P. expansum PE-12 through reverse transcriptase PCR and 5'-3' rapid amplification of cDNA ends (RACE-PCR). The gene is 1266 bp long, including an ORF of 1014 bp, encoding a polypeptide chain of 337 amino...

A protein extract containing a plant lipase from oleaginous seeds of Pachira aquatica was tested using soybean oil, wastewater from a poultry processing plant, and beef fat particles as substrate. The hydrolysis experiments were carried out at a temperature of 40°C, an incubation time of 90 minutes, and pH 8.0-9.0. The enzyme had the best stability at pH 9.0 and showed good stability in the alk...

Alkaliphiles are an interesting group of extremophilic organisms that thrive at pH of 9.0 and above and which are represented by prokaryotes, eukaryotes, and archaea. It is clear that a variety of taxa are represented among the alkaliphiles, some of which are new. Alkaliphiles can be isolated from normal environments such as garden soil, although the number isolated increases dramatically in hi...

Background: In accordance with the German Infection Protection Act, the treatment and handling of laundry was checked by the Public Health Department in 2016 in all Frankfurt nursing homes with special focus on the staff's clothing. Methods: On-site visits and surveys were conducted in all 44 nursing homes in Frankfurt/Main, Germany, and random microbiological examinations of 58 reprocessed and...

Prices for grocery items differ across stores and time because of promotion periods. Consumers therefore have an incentive to search for the lowest price. When a product is purchased infrequently though, the hassle of checking the price on every shopping trip might outweigh the benefit of spending less. I propose a structural model for storable goods, that takes inventory holdings and search in...

The laundry cleaning on an industrial scale has become a highly automated process, carried out by machines using sensors generating very detailed data. Data from these sensors allow the precise control of the laundry operation, often remotely. The combination of new machines with information technology has created a more efficient and cost effective process, enabled by software based on extensi...
