Analysis and evaluation of activated ceramic ball-treated water and its application to cigarette production
The Ceramic water filtration has been greatly improving the most waste materials from drinking water in developing countries. This research was carried out to determine the efficiency of the Ceramic water filters in improving water impurities. The raw materials were grind, sieved with 0.5 mm opening mush size, mixed with water, molded in flower pot shape and fired at 700 °C, 750 °C and 800 °C. The average removing efficiency of the ceramic filters was found to be 59.6%, 86.3%, 87.6%, 56.9%, 59.02%, 88.98%,76.2%, 52.88%, 46.23% and 226.66 m L/h for turbidity, total coliform, E. coli, calc
Efficacies and residue levels of insecticides applied by electrostatic and electric sprayers in tobacco fields
In order to realize the effective monitoring and early warning of potato virus Y (PVY) disease by means of spectral analysis, the spectral data of infected tobacco leaves with different severities were obtained by using ASD non-imaging spectrometer. increased, the spectral reflectance of leaves showed a gradually increasing trend in the visible light band (400-700 nm), and a gradually decreasing trend in the near-infrared band (700-1300 nm). The severity of Y virus disease was significantly correlated with the wavelength, and based on the spectral reflectance of the sensitive wavelengths 45

Pyrolysis and combustion characteristics and kinetics of typical cigar tobacco leaves
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

Effect of biofumigation with marigold stalks on prokaryotic microbial community in tobacco rhizosphere soil
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
Research progress on factors and regulation techniques influencing phenol release in cigarette smoke
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
Identification and validation of nicotine related miRNAs in tobacco
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
Effects of cigarette filter design on release behavior of monomer flavor in breakable capsule
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
Sequencing and analysis of mitochondrial genome of Lasioderma serricorne
In this study, the complete mitochondrial genome of the Lasioderma serricorne was sequenced and analysed. The mitochondrial genome is 14,476 bp long and contains 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and two non-coding region. Twenty three genes were found to be encoded by the majority strand and the other 14 genes by minority strand, those similar to that of other insects. The nucleotide compositing of the majority strand is 39.74% of A, 11.20% of C, 40.47% of T, and 10.39% of G. The phylogenetic analysis by maximum-likelihood (ML) method revealed that the L. serricorne
