The aim of this study was to establish whether the air-conditioning system in buses constitutes an additional source of indoor air contamination with fungi, and whether or not the fungi concentration depends on the period from the last disinfection of the system, combined with replacement of the cabin dust particle filter. The air samples to fungi analysis using impact method were taken in 30 b...

Given its vapor pressure, toluene tends to partition to the atmosphere. Automobile emissions are the principal source of toluene in ambient air, with levels fluctuating in proportion to automobile traffic. Toluene can also be a common indoor contaminant, and indoor air concentrations are often several times higher than outside air. This is likely due to release of toluene from common household ...

production of thermostable alkaline protease in tray bioreactor for solid state fermentation is a unique process which may lead to an economical approach for production of enzyme from agricultural waste or low cost substrate. in solid state fermentation using tray bioreactor, several agricultural residues such as rice bran, sugarcane bagasse, wheat bran, barely bran, corn meal and corn husk wer...

OBJECTIVES To evaluate the efficiency of different automotive cabin air filters to prevent penetration of components of diesel exhaust and thereby reduce biomedical effects in human subjects. Filtered air and unfiltered diluted diesel exhaust (DDE) were used as negative and positive controls, respectively, and were compared with exposure to DDE filtered with four different filter systems. MET...

Abstract Refrigerating compartment with and without shelves is designed for analyzing the air flow temperature distributions by using Simulation software Ansys work bench 14. Comparing results of inside refrigerating shelves. Here considered as obstacles refrigerator freezer a 2D rectangular enclosure one side assumed evaporator wall (cold wall) other Door (warm wall). Inside cabin takes natura...

Considering complex factors of affecting ambient temperature in Aircraft cabin, and some shortages of traditional PID control like the parameters difficult to be tuned and control ineffective, this paper puts forward the intelligent PID algorithm that makes fuzzy logic method and neural network together, scheming out the fuzzy neural net PID controller. After the correction of the fuzzy inferen...

Problem. Currently, the problem of energy independence is one most urgent. Consequently, there a significant need for alternative sources power. Along with this, throughout history human development, issues roads and their quality have been very topical relevant. It especially true Ukraine. With development science technology, these are expanded by functionality roads, safety both drivers other...
