Introduction: The rapid urbanization coupled with industrial development in Indian cities has led to air pollution that causes adverse effects on the health of human beings. So, it is crucial to track the quality of air in industrial areas of a city to insulate the public from harmful air pollutants.  The present study examined and predicted air quality index levels in industrial areas located ...

Heat transfer during the freezing of guava pulp conditioned in large containers such as in stacked boxes (34 L) and buckets (20 L) and unstacked drums (200 L) is discussed. The air velocities across the crosssection of the tunnel were measured, and the values in the outlet of the evaporator were used as the initial conditions in computational fluid dynamics (CFD) simulations. The model tested w...

The investigation of wildlife gastrointestinal microbiomes by next-generation sequencing approaches is a growing field in microbial ecology and conservation. Such studies often face difficulties in sample preservation if neither freezing facilities nor liquid nitrogen (LQN) are readily available. Thus, in order to prevent microbial community changes because of bacterial growth after sampling, p...

Exposure to fine particles can cause various diseases, and an easily accessible method to monitor the particles can help raise public awareness and reduce harmful exposures. Here we report a method to estimate PM air pollution based on analysis of a large number of outdoor images available for Beijing, Shanghai (China) and Phoenix (US). Six image features were extracted from the images, which w...

Production of natural hydrocarbon, transportation and filling into storage is often carried out in the Northern regions and is accompanied by direct contact of droplets produced with the environment cold air. The droplets initially may have a positive temperature. A similar problem occurs when the final product of some chemical substances have liquid – droplet state, the conditions of preservat...

[1] Partitioning of volatile chemicals among the gas, liquid, and solid phases during the conversion of liquid water to ice in clouds can impact the poststorm distributions of chemicals in the troposphere and in precipitation. In this paper, we use a timescale-based methodology to determine the key physical parameters involved in retention and derive the dependence of retention on these paramet...

The effect freeze-drying conditions, i.e. particle size, use of infrared radiation, and drying air temperature in Atmospheric Freeze-Drying (AFD) or freezing rate in vacuum Freeze-Drying (VFD) on the total selenium content, total polyphenols content and anti-radical power of broccoli was investigated. Two factorial designs were used, with three factors in two levels each one, for each type of f...
