However, due to climate change and urbanization, heat stress is becoming more and more serious, affecting public health. This study used the method of calculating effective temperature (ET) to evaluate the spatial and temporal variation of heat stress in Hanoi city from the period 1961 to 2020. Calculation results of the ET value showed that the ET at the hot and fairly hot level was mainly concentrated in June, July, and August. ET tends to increase markedly over time. During the period 1961 - 1997, there was almost no hot ET, but from 1998 to the present, the number of hot ET months occurs frequently in June and July. The number of hot months in the downtown area of Hanoi is much higher than in the surrounding areas. With such a trend in the future, the months of June and July will always have hot ET. The research results are useful documents for management agencies and the health sector to take specific actions to strengthen the health care system, develop infrastructure, and inform the community about the risk of heat stress.","PeriodicalId":17007,"journal":{"name":"Journal of Science Natural Science","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83581345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The method to determine CQ was the test for creative thinking - drawing production (TCT-DP). The results showed that 3% of the students were at A level, 15% are B level, 23% are C level, 44% are D level, 7% are E level, 6% are F level and 2% are G level. Some factors related to family characteristics that reduce the risk of low CQ and increase the posibility of high CQ were: stable occupation of parents, number of children in the family, strict mother, supportive parents when children make mistakes. Factors about children's activities that helped increase their creativity include: volunteer to be a class official, enroll in extracurricular clubs, participating in the artistic activities and enjoy artistic activities.","PeriodicalId":17007,"journal":{"name":"Journal of Science Natural Science","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82458709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Vietnam, this genus has eight species, including five that are in uncertain taxonomy status. In the present study, we described one species of Pareuchiloglanis based on collections from the Da River basin in Phong Tho district, Lai Chau province. Pareuchiloglanis sp. can be distinguished from congeners by the following unique combination of characters: D. i,6; A. i,4; P1. i,14-16 (primarily i,16); C. i,6-8,6-8,i (primarily i,8,8,i); interorbital distanceeye diameter 2.4-3.4; caudal peduncle length 17.1-21.5; caudal pedunle depth 6.0-7.0% SL; length of adipose basedorsal to adipose distance averaged 1.8; head length 19.2-24.3; anal-fin origin closer to the anus than to the caudal-fin base; adipose-fin base posterior to the tip of pelvic-fin rays; the pelvic-fin insertion located opposite to the fourth dorsal fin-ray element; maxillary barbel extending just beyond base of first pectoral-fin element; and yellow patches on dorsal surface (a broader pair on the last doral-fin ray, as large as two thirds length of pelvic-fin). Morphological analysis showed that Pareuchiloglanis sp. are closed to two species in the same surveyed area, P. tamduongensis and P. songdaensis. This paper also indicated morphological differences between Pareuchiloglanis sp. and other species that have yellow patches on dorsal surface. This species record implied the potential of biodiversity of Pareuchiloglanis in the headwaters of the Red River. These findings provide worthy data for further studies on taxonomy of this genus in northern Vietnam.","PeriodicalId":17007,"journal":{"name":"Journal of Science Natural Science","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81497566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
