PRELIMINARY DATA ON ZOOPLANKTON FROM THE CHLEF SHALLOW FRESHWATER PONDS, WESTERN ALGERIA

This work is a contribution to the study of the zooplanktons of the aquatic ecosystems of the Chlef region. This is the first inventory since the last research of Ghauthier 1928. The inventory was based on samples collected from 12 freshwater bodies (reservoirs, ponds, ditches, oueds and dams) during the wet period of 2021. The sites contain a diverse zooplanktons fauna, among which are 3 taxonomic groups: ostracods, cladocerans, and copepods. A total of 15 taxa were identified. Cyclops viridis and Daphnia magna is the most common in the majority of the sampled sites. The Cladocera Corenattell

In vitro culture and plant regeneration of unfertilized male sterile ovules of tobacco

The great economic importance of sugar beet determines the ongoing biotechnological studies conducted worldwide to improve the technology of obtaining doubled haploids (DHs) using the method of unpollinated ovule culture in vitro. To improve the induction of gynogenesis, we tested the effect of thidiazuron (TDZ), temperature bud pretreatment, different concentrations of sucrose, and culturing on liquid or solid medium. Three genotypes were tested in this study. The use of TDZ at a concentration of 0.4 mg/L in solid IMB (induction medium for Beta vulgaris) induction nutrient medium with 3 g/

Realization path analysis to achieve complete tobacco production mechanization based on grounded theory

A complete mechanization process is thought to be inevitable for modern tobacco agriculture development. In order to accelerate the process of tobacco agriculture mechanization from the perspective of organizational management, this paper conducts a retrospective study on the exploration and practice of full-process mechanization in tobacco leaf production in Xuchang, Henan Province as a pilot project. The key points are summarized, and a theoretical model for full-process mechanization in tobacco production is constructed based on the grounded theory, which includes 4 main categories, 12 s

Modification of silo type FIFO cigarette reservoir system for adapting to small batch production

Color preference assay is a test for an animal’s innate and adaptive response to differentiate colors and can be used as an endpoint for psychoactive activity evaluation. Several color preference test methods in aquatic animals that can be used to perform behavioral screening have been established. However, the color preference test conditions have yet to be extensively studied and standardized in aquatic invertebrates. This study aimed to replicate and optimize the previously published method to evaluate the potential color preference in freshwater crayfish based on four different ap

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.
