Effects of quicklime application on bacterial community structure and metabolic function in acidified tobacco-planting soil

Soil acidification is an important factor leading to the occurrence and spread of tobacco bacterial wilt. In this experiment, different amounts of quicklime were used to improve acidified tobacco-planting soil, and the effects of quicklime on structure and metabolic function of bacterial community in acidified soil and the relationships between soil bacterial community and environmental factors were analyzed. The results showed that the appropriate amount of quicklime (1 200-1 500 kg/hm2) improved the Sobs, Shannon, Ace and Chao1 indexes of the bacterial community in acidified soil and the

Characterization of cigarette combustion cone shape and the factors affecting it

Diabetes can cause various vascular complications. The Compounded Danshen-Dripping-Pill (CDDP) is widely used in China. This study aimed to analyze the effectiveness and safety of CDDP in the blood viscosity (BV) with type 2 diabetes mellitus (T2DM). We conducted a systematic search of seven databases from their inception to July 2022 for randomized controlled trials that used CDDP to treat T2DM. To evaluate BV, we measured low shear rate (LSR), high shear rate (HSR), and plasma viscosity (PV). Homocysteine and adiponectin levels were also assessed as factors that could affect BV. We includ

Imaging quality evaluation method for cigarette packet appearance quality inspection apparatus

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

Design of tobacco strip spreader for foreign matter removal device in primary processing line

To improve the efficiency of photoelectric foreign matter removal in tobacco primary processing, a tobacco strip spreader was designed and installed above the rotary roller sorter. The spreader mainly consists of a drive mechanism, an adjustable bracket, a rotating shaft, and a conical disk. Based on the force analysis of tobacco strips on the conical disk and strip spreading experiments, the cone angle of the conical disk was determined to be 29° and the rotation speed to be 79.0 r/min. The minimum diameter of the rotating shaft was 30 mm. The rotating shaft was situated on the adjusta

Quality variation of tobacco stems of different shapes during four-stage controlled atmosphere aging

Forsythia suspensa is a deciduous shrub that belongs to the family Myrtaceae, and its dried fruits are used as medicine. F. suspensa contains several secondary metabolites, which exert pharmacological effects. One of the main active components is forsythin, which exhibits free radical scavenging, antioxidant, anti-inflammatory, and anti-cancer effects. Mitogen-activated protein kinase (MAPKs) can increase the activity of WRKY family transcription factors in a phosphorylated manner, thereby increasing the content of secondary metabolites. However, the mechanism of interaction between MAPKs a

Using near-infrared spectroscopy to evaluate tobacco flavor quality during bidding

In order to improve the efficiency of quality evaluation during the bidding process of tobacco flavors, quality discrimination models for 395 tobacco flavors were established by scanning flavors with their near-infrared spectra and backed by a consistency evaluation method. The models were applied to evaluate the quality consistency of the bidding flavors. The results showed that: 1) The selected wavelength range was from 4 000 cm-1 to 9 000 cm-1, and the first derivative was combined with the Standard Normal Variate (SNV) to pretreat the spectra with a CI (Conformity Index) threshold of 3.

Polyphenol adduct ions based on electrospray mass spectrometry

A rapid, sensitive and selective analysis method using Ultra High Performance Liquid Chromatography coupled to triple-quadrupole Mass Spectrometry (UHPLC-QqQ-MS) has been developed for the quantification of polyphenols in rosé wines. The compound detection being based on specific MS transitions in Multiple Reaction Monitoring (MRM) mode, the present method allows the selective quantification of up to 152 phenolic and two additional non-phenolic wine compounds in 30 min without sample purification or pre-concentration, even at low concentration levels. This method was repeatably appli

Analysis of endogenous floral aroma components and regulation of floral aroma characteristics of mainstream cigarette smoke

Chemicals underlying the floral aroma of dry teas needs multi-dimensional investigations. Green, black, and freeze-dried tea samples were produced from five tea cultivars, and only ‘Chunyu2’ and ‘Jinguanyin’ dry teas had floral scents. ‘Chunyu2’ green tea contained the highest content of total volatiles (134.75 μg/g) among green tea samples, while ‘Jinguanyin’ black tea contained the highest content of total volatiles (1908.05 μg/g) among black tea samples. The principal component analysis study showed that ‘Chunyu2’ and &lsq

Releases of main chemical components and aerosol from aerosol heated tobacco products

Heated tobacco products (HTPs) are novel products that allow users to inhale nicotine by heating (350 °C) reconstituted tobacco rather than combustion (900 °C) as in conventional cigarettes. HTP sticks containing reconstituted tobacco come in various flavours such as menthol, citrus, etc., like electronic cigarette liquids. Thus, the composition of HTP aerosol will also vary according to the flavouring agents added. Overall, the content of toxic chemicals in HTP aerosol appears to be lower than in cigarette smoke. However, the concentrations of more than twenty harmful and potential

Isolation and identification of Bacillus subtilis strain L249 and its control effect on tobacco brown spot disease in pot experiments

In recent years, the bacterial blight of cassava has caused substantial economic losses to the Chinese cassava industry. Chemical control methods have become the primary approach to control this disease; however, their widespread usage and harmful residues have raised concerns about environmental pollution. In order to avoid this, it is urgent to seek a green ecological method to prevent and control it. Biological control through the utilization of microorganisms not only effectively inhibits the disease, but also gives consideration to environmental friendliness. Therefore, investigating a
