Authors: Weiwei Zhang , Ling Yu 
Published: June 2020

Abstract
The main purpose of this study is to investigate the effects of lycopene on oxidative damage and mitochondrial function in the skeletal muscle of mice after strenuous exercise. After the establishment of animal models of exercise-induced fatigue, the mice were randomly divided into four groups: quiet control group, exercise fatigue control group, Low-dose lycopene (20mg/kg) + exercise fatigue group, and high dose lycopene (60mg/kg) + exercise fatigue group. After four weeks, the mice were sacrificed and the levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), malondialdehyde (MDA), free calcium-ion (Ca2+), citrate synthase (CS), values of state 3 respiration (S3) and state 4 respiration (S4) were measured. The results show that lycopene could increase the levels of SOD and GPx in muscle, as well as the levels of free calcium-ion, CS, and values of S4 and respiratory control ratio (RCR) in mitochondria, and decrease the MDA levels in muscle. Lycopene has protective effects against strenuous exercise-induced muscle damage and improves mitochondrial function.

Abstract
Microbes are major contributors to the unique fragrance of Maotai liquor, in which Bacillus sp. is recognized as the main flavor-producing strain. However, studies with respect to the importance, sensitivity and optimal ranges of the factors influencing the flavor components secreted by Bacillus sp. have not been reported. In this paper, a thermophilic flavor-producing strain Bacillus sp., isolated from the black part of Maotai Daqu, was chosen as the representative to study how the factors (inoculum size, temperature and incubation time) influenced the production of flavor components (acetic acid, 2, 3-butanediol and ethyl oleate). The optimal combination of factors as well as the quadratic mathematical model of flavor-producing process were obtained through central composite design analysis by batch tests. Results showed that the simulation accuracy of nonlinear equations for the production of three different types of flavor components was 96.00, 87.76, and 90.54%, respectively. Temperature was the most significant factor influencing the production of flavor components, followed by incubation time, and inoculum size showed the smallest impact. In conclusion, the optimized zones of the three factors were as follows: temperature of 38°C∼45°C, incubation time of 13∼15 d, inoculum size of 14∼17%.

Abstract

Phytophthora nicotianae var. Parasitica and Thielaviopsis paradoxa, often occur in pineapple production. In order to explore the bacteriostatic effect of the extract on the pathogen of pineapple disease, and to provide theoretical basis for the application of the extract on the prevention and control of pineapple fungal disease, the antibacterial activity of three extracts of Eupatorium adenophorum against two pathogenic bacteria of pineapple was studied. Two components with antibacterial activity extracted from the leaves of Eupatorium indica leaves were used as “fungicide”. The antibacterial effects of the three extracts on the pathogens of pineapple heart rot and black rot were studied. The results showed that the crude extracts of H, B, and C components at a concentration of 2 mg / ml against pineapple heart rot and black rot pathogens reached 76.14%, 77.94%, 80.40% and 40.15%, 60.50%. The EC90 values of the crude extracts H, B, and C for pineapple heart rot were 4.48, 2.67, and 4.45 mg / ml, respectively. Respectively, the EC90 values for pineapple black rot pathogens were 10.60, 7.17, and 3.27 mg / ml. Relatively speaking, the three kinds of extracts have better antibacterial effects on pineapple heart rot pathogens than pineapple black rot pathogens; B and C two component substances have great potential to prevent and cure pineapple heart rot and black rot.

Abstract
Nowadays, there are increasing concerns on the protection of environment. Single-serving bottles, made by polyethylene terephthalate mainly, have caused great damages to the harmonious development of human beings, animals and environment. Hence, this paper measures the impacts of single-serving water bottles ban quantitively by constructing sets of models. This project uses AR(p) model to predict the single-serving water bottles usage in future. The result shows that restrictions or bans on single-serving bottles are essential for our earth’s future. There are two major impacts of water bottles: one is the positive impacts (including reducing environmental pollution, reducing energy cost); the other is the negative impacts (including more soft drinks, health cost, and construction cost). The substitution effect model developed by the authors illustrates the influences of the ban on soft drinks as well as tap water. Moreover, the model was applied in the cases of towns, cities and airport, the biggest difference of which is the population density. Due to the limits of tap water, residents in those area with low density are facing high costs to obtain pure water, which causes much bigger inconvenience comparatively. Besides, this paper builds multi-objective model to find the approximate purifier facilities density from the perspective of maximizing carbon dioxide emissions reduction and minimizing costs. The result shows reducing the substitution effect for soft drinks is a good choice of the optimal condition. Besides, enhancing the price of soft drinks is a better method to reduce the negative impacts of a ban on bottled water. In the end, some suggestions are given regarding the water bottle ban, including enhancing soft drinks’ price, advertising the negative impacts of PET bottles to public.

Abstract
To evaluate the potential effect of Urtica cannabina L. (UC)in type 1 diabetes, we herein investigated the hypoglycemic and hypolipidemic effects and the underlying mechanism of ethanol extracted from the aerial part (AUC)and underground part of Urtica cannabina L(UUC) using alloxan-induced hyperglycemic mice model. The aerial part and underground part of Urtica cannabina L was extracted with 95% ethanol was administered orally (AUC and UUC: at 500, 1600mg/kg body weight) every day for 1 weeks to investigate the anti-diabetic effects in alloxan-induced mices. blood glucose and body weight of the mice were recorded daily, and serum levels of total cholesterol, triglycerides and glycosylated hemoglobin were measured. Compared with thediabetic mice, treatment group affected the weight loss of diabetic mice to different degrees and reduced the blood glucose level. The crude extract of Urtica cannabina L also normalizes lipid metabolism parameters. Compared with the diabetic control group, the administration of the high-dose urticaria high-dose group significantly (P <0.05) reduced the levels of serum triglycerides (P <0.05) and cholesterol (P <0.05). This study suggests that in the mouse model of hyperglycemia caused by diabetic alloxan, Urtica cannabina L has significant hypoglycemic and hypolipidemic activity, these provided scientific basis for the high-value utilization of Urtica cannabina L and healthy consumption.

Abstract
Effects of time and height of shading on the sunburn rate, yield and quality of pineapples were investigated in order to provide a theoretical basis for high-quality pineapple production. Golden pineapple was used as the material, and three shading times (30 d, 45 d, and 60 d after flower-fading), and the heights of 0 cm, 20 cm, and 40 cm (the distance from the top of the plant) were set. Golden pineapple’s internal and external fruit qualities were measured. The results showed that the incidence of sunburn of pineapple fruits increased with the delay of the shading time, and no differences were found among three heights at 30 d after flower fading. When pineapple plants were shaded at 30 d after flower fading and at height of 0 cm, pineapple fruits showed good external qualities, including larger fruit size, less fruit eyes, less fruit shape index, larger fruit hardness, higher edible rate and good internal qualities, including higher soluble solid content, higher soluble sugar content and lower total acidity. Shading at 30 d after flower fading and at height of 0 cm was suggested in pineapple production.

Published: June 2020

Abstract
Once the transmission grid of the external UHVDC transmission system has a blocking fault, it will cause high-frequency problems. The adjustment capacity of the system alone often cannot meet the requirements, and the generators need to be tripped in the second defense line of the grid. However, the current tripping method of the high-frequency second line of defense is not systematic. This paper first proposes a simple and practical frequency safety constraint condition. When the system meets the constraint condition, the maximum frequency deviation under a given power disturbance will remain within the set limit. At the same time, based on this constraint condition, a generator tripping optimization model of the high-frequency second line of defense is proposed. The simulation results prove that the tripping solution obtained by solving the model can make the highest frequency and steady state frequency of the system meet the setting requirements, meanwhile, it can reduce the tripping amount and avoid excessive generator tripping.

Published: June 2020

Abstract
Partial discharge along the surface seriously damages the oil-paper insulation performance and ultimately leads to insulation failure, which greatly reduces the safety and reliability of the converter transformer operation. It is important to understand the failure process of oil-paper insulation under partial discharge along the surface to avoid fault occurrence. In this paper, the failure process of oil-paper insulation under partial discharge of pulsating DC and AC voltage is studied. A partial discharge test platform for oil-paper insulation under pulsating DC voltage was built. The partial discharge test of oil-paper insulation along the extremely uneven electric field was simulated by using the needle plate and column plate discharge model. The oilpaper insulation under two kinds of voltages under the extremely uneven electric field was analyzed in depth. The similarities and differences of the failure process and their causes, the insulation design and operation and maintenance recommendations for preventing flashover under the extremely uneven electric field are proposed.
