[Effects of Pesticides Use on Pesticides Residues and Its Environmental Risk Assessment in Xingkai Lake（China）].

Xingkai Lake, located in Heilongjiang Province, is an important fishery and agricultural base and is seriously polluted by agricultural non-point sources. To clarify the residual status of many pesticides in the surface water of Xingkai Lake, 27 types of pesticides, herbicides, and their degradation products were analyzed in rice paddy, drainage, and surface water around Xingkai Lake (China) during the rice heading and maturity periods. The results showed that all 27 types of pesticides, herbicides, and their degradation products were detected during the rice heading period, and the total concentration ranged from 247.97 to 6 094.49 ng·L-1. Additionally, 25 species were detected during the rice maturity period, and the total concentration ranged from 485.36 to 796.23 ng·L-1. In comparison, more pesticides, herbicides, and derived degradation products were detected during the heading period, and their total concentration was higher as well. During the rice heading period, atrazine, simetryn, and paclobutrazol were the main detected pesticides, atrazine and isoprothiolane were the main pesticides detected during the maturity period. The distribution characteristics of pesticides and herbicides in the surface water around Xingkai Lake (China) was similar to that in drainage, so they were probably imported from the drainage and rice paddy. The average risk quotient (RQ) values of atrazine, simetryn, prometryn, butachlor, isoprothiolane, and oxadiazon were higher than 0.1 in drainage and Xingkai Lake (China), which showed a potential risk to aquatic organisms.

Nearly maximal violation of the Mermin-Klyshko inequality with multimode entangled coherent states.

Entangled coherent states for multiple bosonic modes, also referred to as multimode cat states, not only are of fundamental interest but also have practical applications. The nonclassical correlation among these modes is well characterized by the violation of the Mermin-Klyshko inequality. We here study Mermin-Klyshko inequality violations for such multi-mode entangled states with rotated quantum-number parity operators. It is shown that the Mermin-Klyshko signal obtained with these operators can approach the maximal value even when the average quantum number in each mode is only 1, and the inequality violation exponentially increases with the number of entangled modes. This is in distinct contrast with the framework based on displaced parity operators, with which a nearly maximal Mermin-Klyshko inequality violation requires the size of the cat state to be increased by about 15 times.

Vietnamese women immigrants' life adaptation, social support, and depression.

The purpose of this study was to explore the relationships between life adaptation, social support, and depression among migrant Vietnamese women living in Meinong Township, Kaohsiung County. With a cross-sectional study design, 143 participants were recruited by purposive sampling. Structured questionnaires including Demographic Inventory Scale, Life Adaptation Scale, Social Support Scale, and Beck Depression Inventory Scale were used. Data were analyzed with Pearson's correlation and One-way ANOVA. The results showed that Vietnamese women's social support was significantly correlated with the length of time living in Taiwan, the length of marriage, and their husbands' age. Women's social support was significantly different with languages in common, the way of acquaintance with her husband, and family members living together. Depression was significantly different with family income. Life adaptation was also significantly different with family income. Moreover, there was a significantly positive correlation between Vietnamese women's social support and life adaptation, and significantly negative correlations between Vietnamese women's social support and depression, and between their life adaptation and depression. The study findings could be used as references for health professionals and government agencies to institute strategies and policies for promoting migrant Vietnamese women's life adaptation.
