In the current scenario, energy demand in various fields is growing day by day, with human comfort being one of the main areas affected. It is anticipated that the worldwide energy requirement for air-conditioning will triple by 2050, necessitating the need for an energy-efficient alternative. One of the primary challenges in designing and implementing various system components is to increase their performance and reduce energy consumption. To achieve this, various analyses are carried out. Exergy analysis proves to be the most suitable tool for improving and optimizing desiccant regeneration systems. However, performance improvement is not feasible until the main sources of exergy destruction are identified and evaluated. In this study, the exergy analysis of desiccant regeneration using an aqueous lithium chloride solution over an adiabatic single polypropylene (PP) plate vertical falling film tower has been conducted to identify the components and processes in the desiccant regeneration (DR) system responsible for exergy destruction. Additionally, the exergy efficiency of the DR system was calculated.

Plant Hormones in Crop Improvement examines the signaling pathways and mechanisms associated with phytohormones, with particular focus on stress resilience. The growing population of world and unpredictable climate puts pressure on the agriculture production. Current constraints such as increasing temperatures, drought, salinity, cold, nutrient deficiency, along with biotic interactions trigger exquisitely tuned responsive mechanisms in plants. The main coordinators of all stress-related mechanisms are phytohormones, which can be transported over long distances and play a significant role in controlling physiological, agronomic and growth traits, metabolites and sustained crop productivity. Therefore, understanding the mechanisms influencing the stress responses mediated by phytohormones is crucial to ensure the continuity of agricultural production and food security. This book aims to address sustainable agricultural approaches to improve biotic and abiotic stress resilience in crop plants, covering different topics from perception and signaling plant hormones to physiological and molecular changes under different cues. Plant Hormones in Crop Improvement is an essential read for students, researchers and agriculturalists interested in plant physiology, plant genetics and crop yield improvement.
