Over the course of industrial manufacturing,additional heat within the extract systems is usually released into the atmosphere and its intrinsic energy is *** paper investigated a cold abatement smoke extract system for a fire testing wall furnace to determine the viability in recovering heat from the hot *** scenarios were investigated:1)the extract system was closed and only 300°C smoke was present;2)the system took in ambient air around the furnace and heat recovery occurred at 80°C in smoky air;3)the smoke had been removed from the air and the temperature was 60°*** was found that there was a significant build-up of soot on Scenarios 1&2 with a build-up rate of 0.25𝜇m/s which totalled 2.7 mm of soot after a three-hour *** soot had a low heat transfer rate and therefore acted as an insulator on the heat exchanger which reduced the efficiency significantly of it over *** to this loss in efficiency,it was more viable to recover heat in Scenario 3 at 60°C in clean air than it was to recover heat at 300°C or 80°C in smoky *** results show that having clean air was more important than a higher temperature when it came from recovering heat from a cold abatement system for a fire testing *** paper contributes to reveal the possibilities of harnessing the“waste heat”for use in other applications in the vicinity of the manufacturing processes,such as heating water within a central heating plant,domestic hot water or electricity generation,or re-cycled within the industrial plant itself.

３１例临床诊断为颞下颌关节内紊乱征的患者接受了磁共振成像和数字化摄像记录的关节造影检查。两种方法均可对关节盘的位置作出诊断。鉴于磁共振成像能极好的显示和区别骨组织、肌肉、关节盘及关节韧带等结构，且无任何创伤，故为诊断颞下颌关节内紊乱征的一种理想的方法。关节造影仍适用于关节盘穿孔的诊断。临床检查（非影像学检查）诊断的符合率仅为６４．６％。

双倍体酵母细胞Ｄ７经单核能为１１．４ＭｅＶ／ｕ的Ａｎ和Ｕ离子辐照后，测定了细胞随剂量的存活率和突变率。获得细胞对Ａｕ和Ｕ离子的失活截面分别为２．５４μｍ２和１．９２μｍ２。在存活率为３７％的条件下，Ａｕ、Ｕ离子的ＲＢＥ分别为０．２８和０．１９。在突变实验中，研究了ＤＮＡ断链后的重组与倒位，它们对Ａｕ和Ｕ离子的截面为：８．３×１０－２μｍ２［σｍ－ｒｅｃ（Ａｕ）］，９．５×１０－５μｍ２［σｍ－ｒｅｃ（Ｕ）］和６．１×１０－４μｍ２［σｍ－ｒｅｖ（Ａｕ）］和３．８×１０－５μｍ２［σｍ－ｒｅｖ（Ｕ）］．最后，对所获结果进行了讨论。

Fecal samples or cloacal swabs are preferred over lethal dissections to study vertebrate gut microbiota for ethical reasons,but it remains unclear which nonlethal methods provide more accurate information about gut *** compared the bacterial communities of three gastrointestinal tract(GIT)segments,that is,stomach,small intestine(midgut),and rectum(hindgut)with the bacterial communities of the cloaca and feces in the mesquite lizard Sceloporus *** hindgut had the highest taxonomic and functional alpha diversity,followed by midgut and feces,whereas the stomach and cloaca showed the lowest *** taxonomic assemblages of the GIT segments at the phylum level were strongly correlated with those retrieved from feces and cloacal swabs(rs>0.84 in all cases).The turnover ratio of Amplicon Sequence Variants(ASVs)between midgut and hindgut and the feces was lower than the ratio between these segments and the *** than half of the core-ASVs in the midgut(24 of 32)and hindgut(58 of 97)were also found in feces,while less than 5 were found in the *** the ASVs level,however,the structure of the bacterial communities of the midgut and hindgut were similar to those detected in feces and *** findings suggest that fecal samples and cloacal swabs of spiny lizards provide a good approximation of the taxonomic assemblages and beta diversity of midgut and hindgut microbiota,while feces better represent the bacterial communities of the intestinal segments at a single nucleotide variation level than cloacal swabs.
