STRENGTH AND CRACK RESISTANCE OF LONG CYLINDRICAL SHELLS MADE OF REINFORCED CONCRETE AND FIBER-REINFORCED CONCRETE
The methodology of experimental research of long cylindrical shells to determine their stress-strain state, carrying capacity and crack resistance is proposed. To implement the task, the authors have developed a special stand. Eight cylindrical shell models were made for testing - four of reinforced concrete and four of fiber concrete. Fibro-concrete specimens-shells had additional dispersed reinforcement by steel fiber with bent ends in an amount of 1% by volume of concrete. All specimens-shells had a constant length and cross-sectional radius, and varied the thickness of the shell and the si
Composition and diversity of phyllospheric microbial community in tobacco leaves infected by tobacco target spot disease
Blister blight (BB) disease is caused by the obligate biotrophic fungal pathogen Exobasidium vexans Massee and seriously affects the yield and quality of Camellia sinensis. The use of chemical pesticides on tea leaves substantially increases the toxic risks of tea consumption. Botanic fungicide isobavachalcone (IBC) has the potential to control fungal diseases on many crops but has not been used on tea plants. In this study, the field control effects of IBC were evaluated by comparison and in combination with natural elicitor chitosan oligosaccharides (COSs) and the chemical pesticide pyrac
Effects of hydrogen sulfide treatment on seed germination and seedling growth of tobacco
To clarify the effects of hydrogen sulfide (H<sub>2</sub>S) on seed germination and seedling growth of tobacco, the tobacco variety K326 was treated with different concentrations of H<sub>2</sub>S by immersion to observe seed germination; the tobacco seedlings after normal germination were treated with different concentrations of H<sub>2</sub>S, H<sub>2</sub>S inhibitor (HA), H<sub>2</sub>S scavenger (HT) and salt stress via hydroponics to observe their effects on the growth of tobacco seedlings. The results showed that compared wi
Effects of organic acids on nicotine release from heated tobacco product with randomly cut tobacco filling
Heated tobacco products (HTPs) produce aerosol using a different mechanism than tobacco cigarettes, leading to lower emissions of some harmful substances, but also of nicotine as reported by some independent studies. Lower nicotine delivery could lead to compensatory puffing when product use does not sufficiently satisfy cravings. Thus, this three-arm crossover study was conducted to characterize the potential of two different HTPs to deliver nicotine and satisfy cravings compared with conventional cigarettes in users who had already switched to HTPs. Fifteen active, non-exclusive HTP users
Screening and modelling factors that influence cigarette ash integrity based on a feature engineering approach
In order to quantitatively evaluate the ash integrity of a burning cigarette during smoking, a visual evaluation method was established. The pictures of 250 ash columns of burning cigarettes were panel tested with the established method to obtain the score of cigarette ash integrity. The correlations of cigarette ash integrity score with the tested indexes, including grey value, ash crack rate, ash shrink rate, burn line width, burn line uniformity, etc., were studied on the basis of the statistical analysis method of a feature engineering approach. The results showed that: 1) Grey value, a
Appearance quality inspection of cigarette products based on local characteristic similarity metric
Due to the poor adaptability of traditional methods in the cigarette detection task on the automatic cigarette production line, it is difficult to accurately identify whether a cigarette has defects and the types of defects; thus, a cigarette appearance defect detection method based on C-CenterNet is proposed. This detector uses keypoint estimation to locate center points and regresses all other defect properties. Firstly, Resnet50 is used as the backbone feature extraction network, and the convolutional block attention mechanism (CBAM) is introduced to enhance the network’s ability t
Release characteristics of TSNAs in aerosol from heated tobacco products at different heating temperatures
To analyze the effects of heating temperatures on the TSNAs releases in aerosol of heated tobacco products, the release characteristics of TSNAs from three heated tobacco products at different heating temperatures were studied using an in-house designed heating device. The results showed that: 1) The TPM (total particulate matter) released from the three heated tobacco products increased with the increase of heating temperature, and it was extremely significantly linearly correlated with the heating temperature. 2) With the increase of heating temperature, the releases of NNN, NNK, NAB, and
Research progress on tobacco additives in heated tobacco products

Lower nicotine delivery could lead to compensatory puffing when product use does not sufficiently satisfy cravings. Thus, this three-arm crossover study was conducted to characterize the potential of two different HTPs to deliver nicotine and satisfy cravings compared with conventional cigarettes in users who had already switched to HTPs.

Development of automatic cleaning device for second cut circular knife in ZJ118 filter cigarette maker
To remove tipping glue and printing ink residues on the second cut circular knife in ZJ118 filter cigarette maker, an automatic cleaning device for the circular knife was designed. By optimizing the structure of the second cut circular knife mechanism and adding a felt cleaning head with a screw type infeed function, the circular knife is cleaned while it is cutting into the felt cleaning head. At the same time, the felt cleaning head is lubricated to reduce the temperature of the circular knife. The designed cleaning device was tested on two ZJ118 filter cigarette makers at Shenzhen Tobacc
Sensitive detection of pesticide residue maleic hydrazide in tobacco using a fluorescent probe based on 2,7-di (4-pyridyl) acridine
A novel and sensitive fluorescent probe based on Cu2+-modulated polydihydroxyphenylalanine nanoparticles (PDOAs) has been developed for the detection of glyphosate pesticides. Compared to conventional instrumental analysis techniques, fluorometric methods have obtained good results in the field of agricultural residue detection. However, most of the fluorescent chemosensors reported still have some limitations, such as long response times, the high limit of detection, and complex synthetic procedures. In this paper, a novel and sensitive fluorescent probe based on Cu2+ modulated polydihydro
