Current guidelines for green buildings are cursory and inadequate for specifying materials and designing ventilation systems to ensure a healthful indoor environment, i.e. a “healthy building,” by design. Public perception, cultural preferences, litigation trends, current codes and regulations, rapid introduction of new building materials and commercial products, as well as the prevailing desig...

BACKGROUND Intraoperative bacterial contamination is a major risk factor for postoperative wound infections. This study investigated the influence of type of ventilation system on intraoperative airborne bacterial burden before and after installation of unidirectional displacement air flow systems. MATERIAL AND METHODS We microbiologically monitored 1286 surgeries performed by a single surgic...

Information Technology Service Management (ITSM) provides a framework to provide IT related services and the interaction of IT staff with users, and is often related with the British Government’s Information Technology Infrastructure Library (ITIL). ITIL offers a set of “best practices” for managing IT services and is one of the most widely accepted approaches to IT service management in the wo...

When the Digital Evidence Search Kit (DESK) was first used in Mainland China, it was found to be inadequate because it did not support criminal investigations involving popular Internet applications such as QQ, MSN and Foxmail. This paper discusses the enhancements made to DESK to conduct forensic analyses of QQ, MSN and Foxmail.

Even today paper documents are extensively used in offices. This paper presents an application that extends the classical office desk system with an RFID based document tracking techniques. We describe an application that identifies the specific location of paper documents on an office desk to associate this information to related process information in a cooperation support system.

Pushing economy and wheelchair propulsion technique were examined for 8 wheelchair racers on amotorized treadmill at 6.0,6.5, and 7.0 d s . Kinematic data for the sagittal view were collected by a video camera for two-dimensional analysis. Adaptations to speed changes occurred, initially by a decrease in cycle time and an increase in cycle rate, and later by an increase in the flexion of the el...

Abstract Ventilation might play an important role in airborne transmission. By using the computational fluid dynamics (CFD) method, ventilation modes, rates, and infection source’s face direction were considered a multi-person indoor environment (10 m*10 m*3 m). The airflow patterns, virus concentration distribution, probability studied. results showed that was lower with displacement (DV, in, ...
