Like many other industries, today the cleaning industry is affected more than ever by competition and pressure toward low prices, which leads to a nonadvantageous situation for cleaners. These days many Swedish municipalities choose to outsource cleaning service in order to save money, although the situation for the cleaners appears to be worsening. The aim of this paper is to evaluate an alter...

Background During a series of visits to pharmaceutical and fine chemical plants, a SpotView system was used to develop preliminary calibrations for various APIs, excipients, and cleaning materials. The calibrations were based on sets of spectra collected from standard coupons. In the first case, the calibration was challenged with a set of samples that had been independently prepared, some spik...

BACKGROUND Food borne illnesses and food poisoning are cause for concern globally. The diseases are often caused by food contamination with pathogenic bacteria due largely to poor sanitary habits or storage conditions. OBJECTIVES Prevalence of some bacteria on cleaned and sanitised food contact surfaces from eight convenience food plants in Gauteng (South Africa) was investigated with the vie...

Professional cleaning is carried out worldwide in different environments and cleaning workers form an important proportion of the total working population. Cleaning is a fast-developing and fast-growing labour-intensive branch. The aim of the present study was to evaluate the physical stress factors in cleaning work and their relationship with musculoskeletal disorders. The material was collect...

Ultrasonic cleaning of the RBFDP in ethanol for 10 min. The remnants of loose particles after air abrasion may impair wettability of the silane or the primer and the subsequently applied adhesive resin. Ultrasonic cleaning eliminates such remnants best.3 a Professor, University of Zürich, Dental Materials Unit, Center for Dental and Oral Medicine, Clinic for Fixed and Removable Prosthodontics a...

VDI type-1 rig and JIS rig are the two major testing rigs for cleanable fabric filters. We measured the filter cleaning performance using these rigs and the results were compared in order to characterize the two testing methods. The filter performance tests showed that the filter cleaning efficiency measured with VDI type-1 rig is higher than that with JIS rig. During pulse jet cleaning, JIS ri...

In the present world scenario Optical Character Recognition (OCR) has wide variety of applications in the text document image analysis for recognizing individual characters of any language. Digitizing the old documents is a tough job for preserving the essence of the documents to the coming eras. In this paper we are summarizing different image quantitative metrics for estimating the loss of in...

Braces as foreign bodies in the mouth carry a risk of side effects and toxicity to the human body. This article presents the results indicating the possible toxic effects of tools used for cleaning the enamel after the completion of orthodontic treatment. The studies were carried out in vitro. The procedure of enamel etching, bonding orthodontic metal brackets, and enamel cleaning after their r...

BACKGROUND The aim of this study was to evaluate the efficiency and clinical outcomes of mini-open anterior approach focal cleaning combined with posterior internal fixation compared to conventional anterior extraperitoneal approach focal cleaning combined with posterior internal fixation in the treatment of lumbar tuberculosis (TB). MATERIAL AND METHODS Medical records from 124 patients were c...

Through the removal of parasites, dead skin and mucus from the bodies of visiting reef fish (clients), cleaner fish have a significant ecosystem function in the ecology of coral reefs. Cleaners gain nutrition from these interactions and through offering a 'service' are afforded protection from predators. Given these benefits, it is unclear why more fish do not engage in cleaning, and why part-t...
