This paper presents the results of the air quality by the content of CO2, CO, PM2.5, PM10 and the microclimate (temperature and relative humidity) monitoring campaign, in Bucharest underground transport network. The monitoring was performed using both manual and automatic data acquisition systems. All the acquired data were stored in a specific database system used for fast reporting and alarming. GIS software was used to precisely locate the exterior air intakes for selected stations in order to know the quality of the exterior air circulated through them and for finding the best position for new ones. The research was conducted on different station platforms, belonging to the same line, in the Bucharest subway system throughout a year (2015) in order to improve air quality and comfort level of subway stations. The obtained results will serve as basis for improving the air quality and comfort level in the new long subway lines designed and built now in Bucharest. Keywords: indoor microclimate, air quality monitoring, data acquisition systems, temperature-humidity index, Geographic Information System

Abstract: Milk is a nutrient-rich liquid food and it is the primary source of nutrition and a cheap source of protein for large vegetarian population living in India. Dairy industry in India is the world's largest milk producer and dominates about 13% of world milk production. Milk contains several groups of nutrients & considerable amount of organic substances and functional elements such as traces of vitamins, enzymes & dissolved gases, dissolved salts, calcium, water, carbohydrates, proteins, fats, complex & simple lipids, minerals, vitamins , etc.,. Milk transportation has shown to contribute to a greater extent to milk spoilage. Most of the milk which has been rejected by milk processing plants had samples which indicate milk of good quality at farm level before transportation. Milk processors request that milk must be cooled to 2°C to 4°C within 2 to 3 h of milking. The monitoring system that we have implied here is to check the temperature throughout the transportation using micro-controller and to ensure the quality of the milk. This monitoring device consist of NTC Temperature sensor to indicate the exposure to excessive temperature and controlled temperature like cold storage and a gas sensor is used to detect the spoilage of milk while transportation. The RFID tags are used to record the information of the vendor, temperature and how much litre they are giving to the society and hereby, the complete record of this is maintained separately by data acquisition system with the open source software cayenne. In this monitoring device, the temperature of the milk is continuously monitored using microcontroller and an immediate alert message is given to the driver and admin when there is raise in temperature.

The aim of the article is to evaluate the actual situation of thermal comfort in old non-modernized and modernized kindergartens in Lithuania. In this case, the level of thermal comfort and air quality of two modernized and two non-modernized kindergartens is ana- lyzed. In order to evaluate the level of comfort and air quality of the kindergartens, the air temperature, relative humidity and CO2 levels in the air were measured. The study follows the EN ISO 7730 International Standard’s methodology based on Fanger’s Comfort Model. The results of the research presented in this article are supported by the indicators of thermal comfort and CO2 concentration values. According to the calculated average thermal comfort values, the thermal comfort level of two mod- ernized kindergartens and one non-modernized kindergarten falls within the bounds of the comfort zone. Though, the results of CO2 concentration measurements show that in all the kindergartens during the working days CO2 concentration always exceeds the standard requirements.
