Introduction

This chapter explains the linkage between Shelley and Keats in the general culture since the 1820s. It then argues that this conventional pairing obscures the strong differences between the two poets in the nature and scale of their poetic achievement, and in their characteristic poetic styles and themes. This argument is exemplified through detailed analysis of the composition techniques of the two poets, with reference to the manuscript drafts that survive for The Eve of St Agnes and The Triumph of Life. The contrasting poetical manner of the poets is further examined in close reading of the opening stanzas of the ‘Ode on a Grecian Urn’, and the ‘Ode to the West Wind’.

Impact of cement industries dust on soil properties in Bhatapara,Chhattisgarh

The present investigation was carried around cement industries at Bhatapara during 2017-18, to study the different soil properties as affected by the dust of cement Industries in Bhatapara Chhattisgarh. Two hundred fifty six composite soil samples were taken from around the cement industries i.e., from eight radiant wind directions viz., North, South, East, West, Northeast, Northwest, Southeast and Southwest in clockwise manner at the distances 0.5, 1, 2, and 3 km from the surface (0-15 cm) and sub-surface (15-30 cm) soil depths. Statistical analysis was done in 3-factors factorial designed experiment using CRD and the effect of cement dust on soil properties were also correlated with wind directions (X1), distances(X2) and soil depths (X3). Thephysico-properties of soils showed a significant increase in sand and silt in south-west and west wind directions. Significant increase in clay content was also observed in west and south-wind direction. An increase in pH, electrical conductivity and calcium carbonate content in soil (0-15 cm) soil up to 0.5 km distance in the southwest wind direction was also observed. Organic carbon content in soils also increased significantly with increase in distance at surface soilin the southwest wind direction.

Analysis of the Influence of Precipitation and Wind on PM2.5 and PM10 in the Atmosphere

In this paper, hourly observations of precipitation, wind, and PM2.5 and PM10 concentrations in Qinhuangdao from 2016 to 2018 were used to study the effects of precipitation and wind on PM2.5 and PM10 concentrations. The results show that precipitation has a certain wet scavenging effect on PM2.5 and PM10, and the scavenging effect on PM10 is greater than that on PM2.5. Precipitation above moderate rainfall is concentrated from May to September, and light rain in winter increases the concentration of pollutants. The changes of PM2.5 before and after precipitation are related to the initial concentration of PM2.5 before precipitation, precipitation intensity, and precipitation duration. The scavenging effect of precipitation on PM10 is closely related to the initial concentration of PM10 before precipitation. The higher the initial concentration of PM10 is, the greater the removal amount of precipitation will be. Moderate or above pollution weather mainly occurs in the northeast, southwest, and west wind meteorological conditions; the more westerly the wind, the more the pollution; north wind and northwest wind have the most obvious scavenging effect on PM2.5 and Pm10; when the wind speed increases to 2 m/s, the concentration of PM2.5 and PM10 can be reduced; when the wind speed is more than 4 m/s, the concentration of PM10 increases under the south wind, southeast wind, east wind, and northeast wind.

Quantitative evaluation of deterioration in west wind-room in the Palace Museum

The Palace Museum in Beijing is a world cultural heritage site. Surviving nearly 600 years, heritage buildings in the Palace Museum have been deteriorated by salting out, exfoliation, cracking and so on. For the purpose of quantitative evaluation on current environment risks and proposing conservation approaches, heat and moisture transfer on buildings was simulated by a numerical model and the West Wind-room in the Hall of Mental Cultivation (Yangxin Dian) in the Palace Museum was taken as example. The results indicated that to reduce freezing-thawing cycles, the indoor temperature should be increased during December to early February. Indoor temperature and humidity should be controlled to a more stable and lower level to decrease the damaging from salt crystallization and hydration. And attention should be paid to more salting-out resulted by evaporation increase in spring and autumn. The results will provide support to environment control of Chinese traditional buildings.
