THE IMPACT OF BUILDING PARAMETERS AND WAY OF OPERATION ON THE OPERATIVE TEMPERATURE IN ROOMS

1. INTRODUCTION Thermal environment in buildings is one of the most important aspects for occupants’ comfort [1]. Thermal comfort, i.e. satisfaction with the environment depends on the occupants’ thermal sensation. The thermal sensation is a function of four physical variables of indoor environment in the room (air temperature, mean radiant temperature, relative air humidity and air velocity) and two variables related to people (activity level and clothing).

The gas sensing properties of MoO3 thin film is studied at gas concentration 400 ppm and working temperature of 100–400 oC. It was found that the sensitivity depended on the working temperatures and also H2S gas concentration. The results show

THE IMPACT OF TRAILER CONDITIONS ON THE QUALITY OF REFRIGERATED FOOD TRANSPORT SERVICES – A CASE STUDY

The carriage of food products, in particular fresh products, is particularly sensitive to transport conditions. The aim of this paper is to examine the effect of trailer conditions on the quality of refrigerated food transport services. Six wireless measuring devices installed permanently in 3 trailers were used for the analysis. The built-in transmitter sensors have enabled the collection of data in the areas of temperature, humidity, pressure, shock and light intensity. Monitoring parameters

Addition of 9α-hydroxylase inhibitors was not required for preventing the accumulation of byproducts. The effect of pH, tempera­ture, substrate concentration, surfactants and carrier solvents on this bioconversion has been studied. 16-DPA was maximally converted in buffered medium at pH 7.0, at temperature 30°C and 0.5 mg ml–1 substrate

Biofilm Production Potential of Salmonella Serovars Isolated from Chickens in North West Province, South Africa

(Costerton et al. 1999). The formation of biofilms by bacteria has resulted in increasing rates of antimicrobial resistance emerging from the potential to prevent the penetration of antibacterial agents into cells during treatment (Patel 2005) thus making biofilm control medically important. However, very few data has been reported on a substantial correlation that could exists between Salmonella serotypes isolated from chickens, the multiple antibiotic resistance behavior, incubation/storage temperature

AN APPROACH TOWARDS DEVELOPMENT OF PMV BASED THERMAL COMFORT SMART SENSOR

ASHRAE 55-2004 and ISO 7730 standards failed to predict actual comfort level and lead to oversize design of HVAC system. So proper thermal environment monitoring is an important subject to have right size of HVAC systems. A prototype thermal EM system has been developed. Thermal environment parameters such as: temperature, relative humidity, CO and CO2 are measured by using the developed system. These data are used to calculate the thermal comfort index. The subjective judgments and the

Multi-function Monitoring and Alarm System for the Large Stadium

In the recent years, the safety problem in the large stadium has concerned by the researchers. Especially during the period of the large sport, the safety problem of the stadium has become an important public event. This paper designs a multi-function monitoring and alarm system based on the mobile communication network. It could realize the smoke or combustible gas alarm, the infrared identification detection and the temperature alarm. It collects the data through the sensor and sends the data

NANOSTRUCTURED Fe2O3 THICK FILM AS AN ETHANOL SENSOR

Thick films of AR Grade nano Fe2O3 material with n-type semiconducting properties were prepared and tested for their gas sensing performances. Thick films of the materials were prepared by screen printing technique. The gas sensing performance was studied using static gas sensing system. The material was tested for various gases such as CO, CO2, NH3, Cl2, H2, LPG, ethanol and H2S. The nano Fe2O3 film showed maximum sensitivity to ethanol gas at 350 oC temperature at 250 ppm concentration with

SIMULATION OF NOISE WITHIN BOTDA AND COTDR SYSTEMS TO STUDY THE IMPACT ON DYNAMIC SENSING

Real-time structural health monitoring requires dynamic sensing of distributed strain and temperature. Brillouin Optical Time Domain Analysis (BOTDA) and Rayleigh Coherent Optical Time Domain Reflectometry (COTDR) are promising candidates to achieve dynamic sensing. A noise model with specific parametric simulation of independent laser and detector noise sources has been developed. Although ensemble averaging significantly enhances the signal-to-noise ratio (SNR) in both systems, its time

Bactericidal Activity of Octenidine to Various Genospecies of Borrelia burgdorferi, Sensu Lato Spirochetes in Vitro and in Vivo

The aim of our studies was to invent a reliable method for detection of the bactericidal activity of disinfectants against Borrelia burgdorferi in suspension (in vitro) and in cell line cultures (in vivo). In the suspension method, 0.01% octenidine at 20°C and 35°C was bactericidalto Borrelia afzeli; Borrelia garini, B. burgdorferi sensu stricto after 5 minutes treatment. Increase of the temperature to 35°C speed up the bactericidal effect to 1 minute. The bactericidal action of
