A cooling and CO2 enrichment system for greenhouse production using CO2 clathrate hydrate

Abstract

Conditions d'exposition professionnelle des secrétaires d'une entreprise du secteur privé aux douleurs du rachis et des membres supérieurs à Abidjan, Côte d'Ivoire Pain of the spine and upper limbs related to occupational exposure conditions of secretaries in a private sector company in Abidjan, Ivory CoastObjective. To contribute to the improvement of secretaries working conditions. Materials and methods. The study was cross-sectional and descriptive of the working conditions of the service secretaries for at least 1 year of a private sector company in Abidjan. A questionnaire was administered to the secretaries present during the investigation. They were also observed in the workplace. Results. The study included 48 female secretaries, with an average age of 45 AE 8.08 years, mostly overweight or obese (66.7%); 56.25% of the secretaries had more than 10 years of the post; 93.7% of them did not have ergonomic seat. Pain was the main symptom (79.2%). The cervical spine (60.4%) and the thoracolumbar spine (58.3%) were more affected than the shoulders (39.6%). Among the surveyed secretaries, 87.3% (42/48) had not received any training in working gestures or postures. There was a predominance of lesions involving the secretaries following factors: overweight or obesity (90.6%), the position of seniority over 10 years (56.2%), poor working posture (89.7%) and use of non-ergonomic seat (93.7%). Conclusion. Secretaries working conditions are binding. They can be improved by processing workstations, training for secretaries to work postures and gestures, the respect of labor standards on visual display terminal and the appropriate health surveillance. ß

Phase equilibrium and characterization of ionic clathrate hydrates formed with tetra- n -butylammonium bromide and nitrogen gas

“…For this purpose, a separation and storage medium that can rapidly capture and release gases is required. Furthermore, this system can be extended to a large-scale sustainable energy system, i.e., industrial carbon emissions utilized in agriculture [3,4].…”

Nucleation Mechanisms of CO2 Hydrate Reflected by Gas Solubility

“…After separation, CO 2 can be sequestered under the deep sea floor or within natural gas hydrate reservoirs to replace CH 4 13 – 16 . In order to enhance crop photosynthesis 17 , 18 , CO 2 hydrate has recently been proposed as a replacement for CO 2 fertilization in the agricultural industry. In addition, methane hydrate is also attractive because of tremendous energy potential.…”

Experimental and numerical investigation of the thermal performance of evaporative cooled greenhouses in hot and arid climates

“…Higher concentrations of CO 2 within the greenhouse increases the plants growth rates owing to raising net photosynthesis. Plants growth rate benefit from higher CO 2 concentration as the greenhouse reaches the growth optimal temperature (Panwar et al 2011;Umeda et al 2015).…”
