This study evaluated the indoor air quality in Brazilian universities by comparing thirty air-conditioned (AC) (n = 15) and naturally ventilated (NV) (n = 15) classrooms. The parameters of interest were indoor carbon dioxide (CO2), temperature, relative humidity (RH), wind speed, viable mold, and airborne dust levels. The NV rooms had larger concentration of mold than the AC rooms (1001.30 ± 12...

A1. Experimental Facilities During the project two full-scale multi-roomed BMS research facilities were set up, commissioned and used for the investigations presented in this final report; one was at the University of Bradford and the other at the University of Portsmouth. The details of both facilities are presented next. A1.1 Bradford Building Management System This facility comprises three r...

BACKGROUND The crude rate of early-onset Group B streptococcus disease (EOGBS) in Israel has been consistently under 0.5 for 1000 live births for the past 8 years. The Israeli Ministry of Health has adapted the risk factor based approach for preventing EOGBS and universal bacteriological screening for GBS is not recommended. In spite of this policy, there are indications that many pregnant wome...

This study supplemented the National Air Emissions Monitoring Study (NAEMS) by making comprehensive measurements, over a full calendar year, of odor emissions from five swine and four dairy rooms/buildings (subset of the total number of buildings monitored for the NAEMS project). The measurements made in this project included both standard human sensory measurements using dynamic forced-choice ...

This study investigated how automatically activated racial attitudes are affected by relatively long-term interracial relationships. A natural field experiment was conducted in a college dormitory system. Participants were White freshmen who had been randomly assigned to either a White or an African American roommate. Students participated in two sessions during the first 2 and last 2 weeks of ...

Room impulse responses(RIRs) have conventionally been used to derive acoustic parameters to assess acoustics of rooms. One of these parameters is reverberation time which is taken as a crucial measure for perceptual reverberance. Although this measure is not perfect on evaluation reverberance in many situations, especially when the sound decays are not exponential. This study investigates the r...

The utilisation of University teaching space is notoriously low: rooms are often unused, or only half full. We expect that one of the reasons for this is overall mismatch the sizes of rooms and the sizes events. For example, there might be an excess of large rooms. Good space planning should match the set of rooms to the set of events whilst taking account of the pedagogic requirements of the i...

The waiting rooms of general practitioners' surgeries usually have toys provided for children. The level of contamination of these toys and the effectiveness of toy decontamination was investigated in this study. Hard toys from general practitioners' waiting rooms had relatively low levels of contamination, with only 13.5% of toys showing any coliform counts. There were no hard toys with heavy ...

A limited number of rooms are equipped with electronic equipment that allows ETS to remotely monitor AV operations or class capture problems so we can provide instant service without entering the classroom. These 23 rooms are clearly marked with signs alerting users to consider them "public" spaces and to refrain from discussing private or confidential matters. ETS limits the number of persons ...
