Tobacco leaf flue-curing process consumes large amounts of energy. Comparing to the traditional heating approach using coal, the heating source like heat pump would be more energy efficient and environmental friendly. Using heat pump for tobacco drying is proposed in this study. A 3D numerical model is established based on the theory of heat and mass transfer in porous medium. Field measurements were conducted in an actual curing barn in Chongqing. The effects of wall insulation performance and circulating air volume were obtained by comparative analyses of the key parameters. The feasibili
Bacterial wilt as a soil-borne disease was caused by Ralstonia solanacearum, and seriously damages the growth of tobacco. Integrated biocontrol method was explored to control bacterial wilt. Nevertheless, the long-term effects of the integrated biocontrol method on soil bacterial community, soil physicochemical properties and the incidence of bacterial wilt are not well understood. In this study, B. amyoliquefaciens ZM9, calcium cyanamide and rice bran were applied to tobacco fields in different ways. The disease index and incidence of tobacco bacterial wilt (TBW), soil physicochemical prop
In order to clarify the reasons for the good smoke release characteristics of IQOS, the factors that are beneficial to the smoke release characteristics of IQOS were studied by comparing the K (the amount of released smoke was less) and IQOS. The components of IQOS and K which were easy to be released were characterized by the GC-MS. The thermal release characteristics of IQOS, K and the original tobacco powders of K were characterized by the thermogravimetric analyzer (TG). The main compounds of the released smoke of IQOS and K were characterized by Py/GC-MS at two typical heating temperat
Cigarette smoking increases risk for multiple diseases. MicroRNAs (miRNAs) regulate gene expression and may play a role in smoking-induced target organ damage. We sought to describe a miRNA signature of cigarette smoking and relate it to smoking-associated clinical phenotypes, gene expression, and lung inflammatory signaling. Expression profiling of 283 miRNAs was conducted on whole blood-derived RNA from 5,023 Framingham Heart Study participants (54.0% women, mean age 55±13 years) using TaqMan assays and high-throughput RT-qPCR. Associations of miRNA expression with smoking status and ass
This paper describes the effects of non-tobacco, physical cigarette design features on smoke emissions, product appeal, and smoking behaviors – 3 factors that determine smoker’s exposure and related health risks. We reviewed available evidence for the impact of filter ventilation, new filter types, and cigarettes dimensions on toxic emissions, smoker’s perceptions, and behavior. For evidence sources we used scientific literature and websites providing product characteristics and marketing information. Whereas filter ventilation results in lower machine-generated emissions, it also lea
