Impact of Modern Human Activities on the Songhua River’s Health in Heilongjiang Province

The Songhua River is the largest river in Heilongjiang province. During the past decades, intense human activities had extensive effects on the river. Protecting the Songhua River requires diagnosing threats on a large scale. Here we conducted the first comprehensive survey on the rivers’ health throughout the Heilongjiang province, investigating into land use of riversides, modern industries along riversides and other human factors. The results showed that water quality, habitat quality and biological assemblages of the Songhua River are facing deterioration. Farmland, sand dredging operations and tourism depending on water resource may be the main factors which lead to the unhealthy state. This study will be helpful for developing riparian zone restoration plans, or adopting both biological and engineering measures to minimize the degradation of the Songhua River

Interspecific Variation and Phylogenic Architecture of Pinus densata and the Hybrid of Pinus tabuliformis×Pinus Yunnanensis in the Pinus densata Habitat: an Electrical Impedance Spectra Perspective

We evaluated a novel and non-destructive method of the electrical impedance spectroscopy (EIS) to elucidate the genetic and evolutionary relationship of homoploid hybrid conifer of Pinus densata (P.d) and its parental species Pinus tabuliformis (P.t) and Pinus yunnanensis (P.y), as well as the artificial hybrids of the P.t and P.y. Field common garden tests of96 trees sampled from 760 seedlings and 480 EIS records of 1,440 needles assessed the interspecific variation of the P.d, P.t, P.y and the artificial hybrids. We found that (1) EIS at different frequencies diverged significantly among germplasms; P.y was the highest, P.t was the lowest, and their artificial hybrids were within the range of P.t and P.y; (2) maternal species effect of EIS magnitudes in the hybrids and P.d was stronger than the paternal species characteristics; (3)EIS of the artificial hybrid confirmed the mid-parent and partial maternal species characteristics;(4) unified exponential model of EIS for the interspecific and hybrids can be constructed as |Z|=Af -B; (5) cluster analysis for species and hybrid combinations in total corroborated with the previous hybrid model of Pinus densata. Our non-destructive EIS method complemented the previous finding that Pinus densata was originated from P.t and P.y. We conclude that the impedance would be a viable indicator to investigate the interspecific genetic variations of conifers

A STUDY OF THE RELATIONSHIP BETWEEN BIOMECHANICS PARAMETERS AND SPECIFIC PERFORMANCE IN DIFFERENT VERTICAL JUMPS OF FEMALE WEIGHTLIFTER

The angle and its speed etc biomechanics parameters of hip and knee joint of 12 female lifters who adopted 5 different jump mode have been collected. Correlation analysis has been done between the collected data and specific performance. The result shows that different extent correlation between jump height in different mode and specific performance. In these correlations, biomechanics parameters in 60cm dropping jump have the most correlation factors. Especially elasticity energy utilizing rate and the height of dropping jump have the high extent correlation coefficient is about muscle speediness strength and muscle strength in allusion to female Iifter. That is 60cm feasible height

Capacitance Characteristics of Pinus densata, Pinus tabuliformis, Pinus yunnanensis and the hybrids Pinus tabuliformis × Pinus Yunnanensis

We employed capacitance to evaluate the kinship and interspecific variation of homoploid hybrid conifer Pinus densata, P. tabuliformis, P. yunnanensis and artificial hybrids of P. tabuliformis (maternal parent) and P. yunnanensis (paternal parent) which were cultivated and selected in the common garden experiment. By measuring capacitance spectra under different voltage frequencies, we could differentiate different germplasms based on the electrical response. We aims to demonstrate that P. densata as the hybrid of P. tabuliformis and P. yunnanensis based on the capacitance values of the species, and to provide new evidence to the previously known biological evidence, as well as and the parental effect on the hybrids. Our results revealed that capacitance values between the species are significantly different in the spectra where P. yunnanensis positioned at the lowest and P. densata was much higher than all other species, indicating that P. densata had possessed a great capacity to store electrical energy. The capacitance spectra of P. densata and the artificial hybrid are not similar, which rejected our hypothesis. Both of the capacitance values of P. densata and the hybrids were closer to P. tabuliformis than to P. yunnanensis, which shows that the maternal influence was stronger than the paternal influence. Correlation analysis on the relationship between capacitance and fitnessrelated characteristics showed that capacitance is negatively correlated to mortality rate, and positively correlated with second-year survival rate. High capacitance values of P. densata and some of the hybrids reveal their superior adaptability to harsh environment in the Tibet Plateau. We concluded that capacitance as a new indicator for plant fitness and evolution evidence of homoploid hybrid conifers

Effect of Yuanbao Maple Tea Powder with High Chlorogenic Acid Content on Bread Quality

Using Yuanbao maple leaves as raw materials, the extraction process of chlorogenic acid in leaves was optimized, and single-factor and orthogonal experiments were carried out on ultrasonic temperature, time, and solid-liquid ratio through ultrasonic extraction. The results showed that the optimal level of the experiment was when the ratio of solid to liquid was 16:1, the concentration of ethanol was 60%, and the ultrasonic time was 15 min, and the extraction amount was 6.86% (mass fraction). Under the optimal extraction process conditions, the dynamic content of chlorogenic acid in the growth cycle of Yuanbaofeng in 2020 was analyzed. The results showed that the content of chlorogenic acid in the leaves of Yuanbaofeng in June was the highest, and the content in September was the least. In order to further explore the effect of Yuanbao maple tea powder on bread quality, different proportions of Yuanbao maple tea powder were added to bread to study its sensory effects on bread. The effects of scores, moisture content, texture, polyphenol content, antioxidant activity and other qualities. The results show that the water holding capacity, elasticity and anti-oxidation of bread are the best when the addition amount of GTB is 0.5%. Less elastic, more difficult to chew, and gradually unstable antioxidant properties

On the improvement measures of interior noise reduction of minivan’s roof based on acoustic modal analysis

In this work, three types of measures, i.e., 1) adding the damping adhesive, 2) changing the local beads and 3) utilizing the dynamic vibration absorber (DVA), are performed to investigate and improve the acoustic quality of the minivan’s interior noise. For adding the damping adhesive, the difference of the adhesive location directly affects the mode of minivan’s roof. For changing the local beads, eight cases of beads are selected. The results indicate that the change trend of the first natural frequency is parabolic as the number of beads increases. For adding the 33 Hz DVA, the results show that the sound pressure levels (SPLs) of the minivan’s response points located at the front, middle and rear seat in the critical frequency are approximately reduced by 2.1 dB, 1.5 dB and 1.1 dB in the minivan’s simulation, and by 2.6 dB(A), 1.4 dB(A) and 2.7 dB(A) in the minivan’s road experiment, respectively. By contrast, the DVA with a certain frequency should be chosen if the reduction of sound pressure level (SPL) is only considered. Furthermore, if the SPL’s reduction and the additional mass are taken into account at the same time, the measure with local flatted beads should be selected. The obtained results could provide a certain practical guiding significance for improving the mode and interior noise of minivan’s roof
