There has been a long history of interest on how(if)the absorption coefficient of“pure”fresh water(a_(fw)(λ))and“pure”seawater(a_(sw)(λ))changes with temperature(T),yet the impact of T reported in the literature differs significantly in the blue *** the previous studies based on laboratory measurements,we took an approach based on~18 years(2002–2020)of MODIS ocean color and temperature measurements in the oligotrophic oceans,along with field measured chlorophyll concentration and phytoplankton absorption coefficient,to examine the relationship between T and the total absorption coefficient(a(λ))at 412 and 443 *** found that the values of a(412)and a(443)in the summer are nearly flat(slightly decreasing)for the observed T range of~19–27℃.Since there are no detectable changes of chlorophyll during this period,the results suggest that T has a negligible impact on a_(sw)(412) and a_(sw)(443)in this T *** a complement,the impact of salinity on a_(fw)(λ) was also evaluated using three independent determinations of a_(sw)(λ) and a_(fw)(λ),where good agreements were found from these observations.

Anatase TiO_(2) is a promising anode material for lithium-ion batteries(LIBs)owing to its low cost and ***,the intrinsically kinetic limits seriously hindered its lithium-ion storage *** we present that anatase TiO_(2) with rich oxygen vacancies can enhance its lithium-ion storage *** synthesize anatase TiO_(2) with well-retained hierarchical structure by annealing the H_(2)Ti_(5)O_(11)·3H_(2)O yolk-shell spheres precursor in nitrogen *** and XPS data evidence that the oxygen-deficient environment could generate abundant oxygen vacancies in the as-derived anatase TiO_(2),which leads to improved electron conductivity and reduced charge-transfer *** rich oxygen vacancies and high structural integrity of the hierarchical yolk-shell spheres enable the as-derived anatase TiO_(2) yolk-shell spheres with a high specific capacity of 280 mah g^(-1) at 100 ma g^(-1) and 71%of capacity retention after 5000 cycles at 2 A g^(-1).

中国共产党与越南共产党作为社会主义国家的执政党,自改革(革新)开放以来不断致力于党内法规制度建设,以党内治理规范化、法治化推进两党治党管党与治国理政能力的提升。但因在国情、党情方面存在的总体相似性与具体差异性,两党在推进党内法规制度建设的理念、具体做法、发展态势、具体成效等方面既表现出一定的共性,又呈现出各自的特点。当前,在中共、越共两党深入推进本国改革(革新)开放的时代背景下,对中共与越共两党加强党内法规制度建设问题进行比较研究,有利于中共与越共两党在党内法规制度建设方面互学互鉴,推进各自党内法规制度建设不断深入发展。

Background:Drowning is a major cause of morbidity and mortality for children,yet non-fatal drowning remains pooriy *** aim of this study was to explore potential modifiable risk factors of non-fatal drowning among children in rural areas of China. Methods:A cross-sectional survey was first conducted to obtain non-fatal drowning cases,and 7432 students in grades three to eight from 17 schools participated in the cross sectional *** these,805 students reported that they experienced non-fatal drowning in the previous *** 368 cases were selected randomly to participate in a 1:1 matched case-control *** drowning case was matched by one control with the same sex and similar age(the gap less than 2 years) who was selected randomly from the same class. Results:Boys were more litely to be involved in non-fatal ***-fatal drowning most often happened in the afternoon(65.1%) and natural bodies of water were the most common sites of drowning(71.1%).Swimming, diving and playing in natural waters were the leading activities that preceded non-fatal *** significant risk factors for non-fatal drowning were swimming in natural waters without adult supervision(OR = 3.40,95%CI: 1.92-6.03),playing in or beside natural waters(OR = 2.08,95%CI:1.17-3.70) and poor swimming skills(OR - 2.74. 95%CI:1.14-6.62).However,the following variables were protective factors:supervisor aged 30 years or over(OR= 020,95%CI:0.09-0.49) and no water activities(OR=0.36,95%CI:0.18-0.70). Conclusions:The reduction in dangerous water activities,swimming training and enhancement in supervision among children might decrease the risk of non-fatal drowning.
