Nocardioforms were genetically identified using PCR-REBA. PCR-REBA was able to identify many bacterial genera in one assay. PCR-REBA was able to determine that foams from different WWTPs contain various types of bacteria such as Gordonia spp., Millisia spp., Skermania spp., Tsukamurella spp., and Microthrix parvicella, while light microscopy cannot differentiate amongst them (except M. parvicel...

We review work done at UCSD on persistent photoconductivity and photoinduced superconductivity in REBa,Cu~O, thin films. It is shown that the resistivity, Hall coefficient and c-axis parameter change significantly upon illumination. All these effects require the presence of oxygen vacancies. The maximum enhancement of the conductivity with illumination occurs for fully deoxygenated ,samples (x=...

BACKGROUND During the last decades, to assess the risk factors of work-related musculoskeletal disorders (WMSDs), enormous observational methods have been developed. Rapid Entire Body Assessment (REBA) and Quick Exposure Check (QEC) are two general methods in this field. This study aimed to compare ergonomic risk assessment outputs from QEC and REBA in terms of agreement in distribution of post...

Web applications suffer from poor reliability. Practitioners commonly rely on fast failure detection to recover their applications quickly to reduce the effects of the failures on other users. In this paper, we present a technique for detecting user-visible failures by analyzing Web logs. Our technique applies a first-order Markov model to infer anomalous browsing behavior discovered in Web log...

OBJECTIVES Musculoskeletal disorders (MSDs) compose a large part of occupational diseases in dental professionals, prevention of which is dependent on assessment and improvement of job postures by means of ergonomic interventions. This study was aimed at evaluation of ergonomic conditions of the profession of dentists and also at assessing the relationship between MSDs and conditions of work. ...

Introduction: Musculoskeletal disorders (MSDs) are increa­ singly becoming a nuisance for dental professionals. Nearly, 2 million workers across the world suffer from MSDs each year, with dentists facing an increased risk of developing these ailments. This study is an attempt to assess the risk of MSDs among dental professionals, and eventually to spread awareness regar­ ding the importance of ...
