Multiscale Static Compressive Damage Characteristics of Kiwifruit Based on the Finite Element Method.

In the handling or processing process, fruits are easily crushed by external loads. This type of damage in fruit often leads to the internal pulp browning and rotting, with the severity largely dependent on the fruit tissue's geometric and mechanical properties. In kiwifruits, with their thin skin and dark-colored flesh, it is particularly challenging to observe and analyze the damage caused by extrusion through traditional experimental methods.

Six experimental diets with different protein levels (26%, 29%, 32%, 35%, 38%, 41%) were formulated. A total of 540 fish with an initial weight of 11.

Development of Cotton Picker Fire Monitoring System Based on GA-BP Algorithm.

Due to the characteristics of the cotton picker working in the field and the physical characteristics of cotton, it is easy to burn during the operation, and it is difficult to be detected, monitored, and alarmed. In this study, a fire monitoring system of cotton pickers based on GA optimized BP neural network model was designed. By integrating the monitoring data of SHT21 temperature and humidity sensors and CO concentration monitoring sensors, the fire situation was predicted, and an industrial control host computer system was developed to monitor the CO gas concentration in real time and display it on the vehicle terminal.

Application of Convolutional Neural Network-Based Detection Methods in Fresh Fruit Production: A Comprehensive Review.

As one of the representative algorithms of deep learning, a convolutional neural network (CNN) with the advantage of local perception and parameter sharing has been rapidly developed. CNN-based detection technology has been widely used in computer vision, natural language processing, and other fields. Fresh fruit production is an important socioeconomic activity, where CNN-based deep learning detection technology has been successfully applied to its important links.

Effective Adsorption and Sensitive Detection of Cr(VI) by Chitosan/Cellulose Nanocrystals Grafted with Carbon Dots Composite Hydrogel.

Due to its lethal effect on the human body and other creatures, Cr(VI) ions have attained widespread public attention, and an effective adsorbent for removing Cr(VI) ions is vital. Chitosan (CS)/cellulose nanocrystals grafted with carbon dots (CNCD) composite hydrogel with strong sorption ability and sensitive detection ability for Cr(VI) was formed. The cellulose nanocrystals (CN) offered a natural skeleton for assembling 3D porous structures, and then improved the sorption ability for Cr(VI); moreover, carbon dots (CD) acted as a fluorescent probe for Cr(VI) and provided Cr(VI) adsorption sites.

Identification of a consensus DNA-binding site for the TCP domain transcription factor TCP2 and its important roles in the growth and development of Arabidopsis.

TEOSINTE BRANCHED 1/CYCLOIDEA/PROLIFERATING CELL FACTOR 1 (TCP) transcription factors control multiple aspects of growth and development in various plant species. However, few genes were reported to be directly targeted and regulated by them through their specific binding sites, and then uncover their functions in plants. A consensus DNA-binding site motif of TCP2 was identified by random binding site selection (RBSS).

Childhood Nutrition in Rural China: What Impact Does Public Health Insurance Have?

Objectives: To investigate the impact of public health insurance coverage, specifically the New Cooperative Medical Scheme (NCMS), on childhood nutrition in poor rural households in China, and to identify the mechanisms through which health insurance coverage affects nutritional intake.

Methods: Longitudinal data on 3291 children were taken from four time periods (2004, 2006, 2009, and 2011) from the China Health and Nutrition Survey (CHNS). Panel data analysis was performed with the fixed-effect model and the propensity score matching with difference-in-differences (PSM-DID) approach.

A xylanase with broad pH and temperature adaptability from Streptomyces megasporus DSM 41476, and its potential application in brewing industry.

A xylanase gene, xynAM6, was isolated from the genomic DNA library of Streptomyces megasporus DSM 41476 using colony PCR screening method. The 1440-bp full-length gene encodes a 479-amino acid peptide consisting of a putative signal peptide of 36 residues, a family 10 glycoside hydrolase domain and a family 2 carbohydrate-binding module. The mature peptide of xynAM6 was successfully expressed in Pichia pastoris GS115.

[Effects of Cd2+ on seedling growth and phytohormone contents of Glycine max].

A laboratory incubation experiment was conducted to study the effects of different Cd2+ concentrations on seedling growth and phytohormone contents of Glycine max through determining some physiological and biochemical indexes. The results showed as follows: (1) Different Cd2+ concentrations inhibited the synthesis of indoleacetic acid (IAA) and gibberellins (GA3) in roots and stimulated the synthesis of zeatin (Z) and abscisic acid (ABA) not only in roots but also in aerial parts of Glycine Max. Cd2+ stimulated the synthesis of IAA and GA3 in aerial parts at lower concentrations, but inhibited the synthesis of IAA and GA3 at higher concentrations.

[Effects of lead stress on anti-oxidative enzyme activities and isoenzymes in cucumber seedlings].

With hydroponics and polyacrylamide gel electrophoresis (PAGE), this paper studied the effects of lead stress on the activities of peroxidase (POD), superoxide dismutase (SOD) and catalase (CAT), and their isoenzymic band numbers in cucumber seedlings. The results showed that the isoenzymic bands and expression quantity of POD decreased gradually with increasing lead concentration. The SOD activity increased with increasing lead concentration within the range of 0-500 mg Pb x L(-1), reached the maximum at 7th day, and then decreased rapidly, being lower than the control of the same period.
