Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Soil Temperature Regime at Ahmedabad [PDF]

open access: possibleJournal of Agricultural Engineering (India), 2002
A 3-m deep probe with five PT 100 temperature sensors was installed at the campus of Indian Institute of Management, Ahmedabad in August, 1999 to monitor temperature at various depths. Hourly values from all the sensors were noted one day in each month for a year.

Effect of Groundwater Level on Soil Moisture, Soil Temperature and Surface Temperature

Journal of the Indian Society of Remote Sensing, 2021
The dynamic behavior of groundwater level effects the soil moisture, soil temperature and surface temperature. In the study, the effect has been studied at two observation sites with varying groundwater level. Regular measurements of soil moisture and soil temperature were taken in field at 1.5, 2.2 and 3 m depth to observe the groundwater level effect

Annual soil temperature evolution

Il Nuovo Cimento C, 1991
A model to study the annual behaviour of the temperature of a homogeneous solid (considered like a semispace) will be presented in this paper. The model gives the temperature of the solid at any time and at any depth. It assumes the solar flux as the incoming flux, constant atmospheric effects and a simple expression for the outgoing flux.

Soil temperature regime and vulnerability due to extreme soil temperatures in Croatia

Theoretical and Applied Climatology, 2015
Soil temperature is an important factor within the climate system. Changes of trends in soil temperature and analysis of vulnerability due to heat stress can provide useful information on climate change. In this paper, the soil temperature regime was analyzed on seasonal and annual scales at depths of 2, 5, 10, 20, 30, and 50 cm at 26 sites in Croatia ...

Soil Temperature and Heat Transport in Soils

2018
Soil temperature varies over a wide range, depending on annual and diurnal cycles of incoming solar energy and on the soil surface properties. Plants can grow when soil root zone temperatures are in the relatively narrow range 0–40 °C. Soil-water hydraulic conductivity and soil-water retention curves are functions of temperature because of the ...

Effect of Temperature on the Consolidation of Soils

Nature, 1950
IN civil engineering practice it is sometimes necessary to estimate the probable rate of settlement of structures founded on clay and other compressible soils. The settlement arises from a process in soil known as consolidation, in which the application of a load to the surface of the soil causes water to be expelled from its pores.

Soil Temperature and Soil Heat Flux

2016
The soil temperature regime depends on its thermal properties (specific heat, thermal conductivity, thermal diffusivity and thermal admittance). The main factors affecting the thermal regime are water content, soil texture and compaction. The rate of heating (or cooling) of the soil is proportional to its diffusivity which is higher in sandy soils. The
