Abstract
The present study aimed to investigate the effects of undenatured type II collagen on monosodium iodoacetate-induced osteoarthritis (OA) rats, and elucidate its underlying anti-inflammatory and antioxidant mechanisms. Several parameters such as body mass, pain threshold of knee joint, supporting force of the left and right feet, serum levels of inflammation mediators and cartilage metabolic marker, malondialdehyde (MDA) content, superoxide dismutase (SOD) activity and knee joint histopathology were measured. The results demonstrated that undenatured type II collagen enhanced the pain threshold of knee joint and reduced the difference in supporting force between the left and right feet. Moreover, undenatured type II collagen increased serum TGF-β concentration and decreased the serum levels of TNF-α, MMP-13 and CTX-II in OA rats. In addition, decreased serum MDA content and increased serum SOD activity were found in undenatured type II collagen treatment group when compared to those in model group. Histopathological data indicated that undenatured type II collagen exhibited protective effects on both synovial and cartilaginous tissues in OA rats. Taken altogether, the findings of this study reveal that undenatured type II collagen can relieve and prevent OA symptoms by regulating inflammatory mediators and oxidative stress. Additionally, this collagen helps to reduce knee OA pain and maintain normal joint function.

Abstract
Fruit is a major pillar industry for economic development in many regions of China, and it is the third largest crop after crops and vegetables. However, the level of mechanization of fruit harvesting is still in its infancy, and most of them are mainly manual harvesting. The workload is heavy, the picking intensity is not easy to grasp, and it is easy to damage the fruit. Based on the research of fruit picking devices at home and abroad and field visits to orchards, this paper draws up design schemes and conducts main structural design and parameter calculations. The product can achieve 10 kinds of picking work, such as fruit apple, peach, orange, litchi. This greatly reduces the labor intensity of the picking work, improves the efficiency of the picking operation, and provides reference design experience for the fruit picking industry.

Published: November 2020

AbstractAs a widely used herbicide in the world, glyphosate occupies an important position in the global agrochemical market. the first genetically modified glyphosate-resistant crop was successfully studied in the United States. Monsanto, as a giant in the agrochemical field, has extensive influence in the field of genetically modified glyphosate resistance. Phosphoenolpyruvate shikimate synthase ((EPSPS)) is a key enzyme that catalyzes the synthesis of EPSP from PEP and S3P in shikimic acid pathway. As an important prerequisite for branched acid synthesis in photosynthesis, shikimate synthase plays an important regulatory role. Glyphosate is the structural analogue of S3P, which competitively inhibits the enzyme activity of EPSPS, resulting in the interruption of shikimic acid pathway, which leads to the death of plants. According to their conserved domains, EPSPS can be divided into type I EPSPS and type II EPSPS, type I EPSPS sensitive to glyphosate, while type II EPSPS is inherently tolerant to glyphosate, and the two types of EPSPS have specific mutants, showing different degrees of sensitivity to glyphosate inhibition in the catalytic shikimic acid pathway. Based on China knowledge Network and other databases, mining the current types, sequence characteristics and transformation events of glyphosate-resistant genes will help our country to occupy a favorable position in the field of glyphosate-resistant transgenic and maintain the agricultural security of our country.

Abstract
In order to improve the oil adsorption performance of biomass carbon, a new oil removal adsorbent was prepared by modifying natural material. Hydrophobic agent is used as modifier to graft biomass carbon. The structural characteristics and microstructure of biomass carbon treated by modifiers are characterized by FTIR spectroscopy and SEM observation. The results showed that self-made biomass charcoal has good floatability, and biomass carbon treated by the hydrophobic agent has a higher oil adsorption capacity than those of untreated ones. Peanut shell carbon and corn cob carbon modified by nano-SiO2 dispersant obtained the best results with an oil absorption rate of about 1.5 g/g and an oil retention rate of about 95%. As determinate by GC/MS, the modified biomass carbon before and after the adsorption of marine oil, the alkane changed significantly, indicating that the adsorption capacity of oil is very obvious.

Published: November 2020

AbstractAlong with the times and technology, more often we find housing or offices that use a smart home system or smart building that integrates electrical appliances at home and offices into a single system, for example, lighting, air conditioning, security systems, etc. The use of electrical equipment that uses a system with an inverter technology can trigger disturbances related to the frequency switching used. The disturbance may affect the energy measured by energy meter. The study observes the impact of electric disturbances at frequencies range of 9-150 kHz on kWh meter. The disturbances are generated manually using Personal Computer and injected to the system through coupling network device. The disturbance generated has single and multifrequency disturbance in the range of 9-150 kHz. The result shows that there are inaccurate measurements on the analogue kWh meter when exposed to disturbances with an average percentage error of 2.91%. What can be done in the future is to install filters to reduce disturbances at these frequencies so as not to interfere with the performance of these devices.

Abstract
The Vertical Axis Wind Turbine (VAWT) can generate electricity by low wind speed and it can be simply implemented for scattered electricity loads. The objective of this study was to determine the specification, quantity, power capacity, capacity factor, and optimum production cost of the VAWT. Based on historical data of the wind speed, the future wind speed distribution can be simulated by using the Weibull and Rayleigh distribution approach. The parameters varied in this simulation included turbine specification, power capacity, and wind speed. The result showed that the optimal design of VAWT to implement in Raja Ampat was 10 kW turbine Type-H darrieus, with 3.5 m/s cut-in speed, 12 m/s rated speed and 9.49% capacity factor. This individual turbine can generate 8313 kWh Annual Energy Production or can supply the demand amount 432,983 kWh by 39 units with LCOE 20.5 Cent USD/kWh/unit or lower than Production Cost Regulated (21.34 cent USD/kWh). This indicated that the vertical axis wind turbine was the techno-economically appropriate alternative for archipelago countries that had scattered electricity loads such as Indonesia.
