Journal of Traffic and Transportation Engineering(English Edition) 2019年第4期6卷 349-358页

In most countries, there is a low temperature limit to lay down hot asphalt mixes because if it is too cold, it becomes impossible to get proper compaction. For cold recycled bituminous mixture(CRM), there is little information on the effect of the low temperature on their behavior. The goal of this study is to evaluate, in laboratory, the impact of the compaction and curing temperature on the behavior of CRM. To do so, CRM containing 50%reclaimed asphalt pavement(RAP) and 50% natural aggregates treated with foamed asphalt or bituminous emulsion were mixed and cured at different temperature between 0 and23℃ for up to 10 days before being tested in indirect tension. The results show that for all mixes, a cure at lower temperature means lower tensile strength, but the decrease is more noticeable for emulsion treated materials than for foamed treated mixes. The trend is not as obvious for marshall stability results. A second cure at ambient temperature was also done, and the analysis of the results showed that the decrease in mechanical performance remains important even after a second cure at higher temperature for all mixes treated with bituminous emulsion, but there is some mechanical gain for mixes treated with foamed asphalt.

Background： The immense growth in global bioethanol production has greatly increased the supply of by-products such as whole stillage and condensed distiller＇s solubles, which could be potentially used for animal feeding. The objective of this study was to investigate effects of liquid feeding high levels of corn condensed distiller＇s solubles（CCDS） and whole stillage（CWS） on growth performance, carcass characteristics, belly firmness and meat sensory traits of ***： A total of 256 pigs were blocked by sex and initial BW（13.5 ± 2.5 kg）, and pens of pigs（8 pigs/pen） were randomly allocated to 1 of 4 dietary treatments（8 pens/treatment）： 1） corn-soybean meal based diet as control, 2） 25%CWS ＋ 5% CCDS, 3） 19.5% CWS ＋ 10.5% CCDS, and 4） 19.5, 26, and 32.5% CWS ＋ 10.5, 14, and 17.5% CCDS in phases 1（28 d）, 2（38 d）, and 3（60 d）, respectively. Inclusion levels of CCDS and CWS for Treatments 1, 2, and 3 were fixed during all the three phases of the experiment. Inclusion levels of CWS and CCDS were on 88% dry matter basis. The liquid feeding system delivered feed from the mixing tank to feed troughs by high-pressure air, had sensors inside feed troughs, and recorded daily feed intake on the basis of a reference feed intake curve. The pigs were fed 5 to 10 times per day with increasing frequency during the ***： Control pigs had greater（P 0.10） dressing percentage, loin muscle depth, and lean percentage were observed among the four treatments. Inclusion of CWS and CCDS reduced（P 0.10） the overall like,flavor, tenderness and juiciness of loin chops when compared with the control ***： In conclusion, our results indicate that including 30–50% of a mixture of whole stillage and condensed distiller＇s solubles in the growing-finishing diets may reduce growth performance, carcass weight and belly firmness, but does not affect pork sensory traits.

Endoscopic ultrasound(EUS)-guided fine needle aspiration with or without biopsy(FNA/FNB) are the primary diagnostic tools for gastrointestinal submucosal tumors. EUS-guided fine needle aspiration(EUS-FNA) is considered a first line diagnostic method for the characterization of pancreatic and upper gastrointestinal lesions, since it allows for the direct visualization of the collection of specimens for cytopathologic analysis. EUSFNA is most effective and accurate when immediate cytologic assessment is permitted by the presence of a cytopathologist on site. Unfortunately, the accuracy and thus the diagnostic yield of collected specimens suffer without this immediate analysis. Recently, a EUS-FNB needle capable of obtaining core samples(fine needle biopsy, FNB) has been developed and has shown promising results. This new tool adds a new dimension to the diagnostic and therapeutic utility of this technique. The aim of the present review is to compare the efficacy of EUS-FNA to that afforded by EUS-FNB in the characterization of pancreatic masses and of upper and lower gastrointestinal submucosal tumors.

In many countries cacao (Theobroma cacao L.) is invariably grown as an understory crop in agroforestry types of cropping systems and subjected to low levels photosynthetic photon flux density (PPFD) due to presence of large number of upper story shade trees with poorly managed canopy structure. In recent years carbon dioxide concentration in the atmosphere is steadily increasing and it is unclear what impact this will have on performance of cacao grown under shade of upper story shade trees. A climatically controlled greenhouse experiment was undertaken to evaluate the effects of ambient and elevated carbon dioxide (400 and 700 μmol·mol-1) and three levels of PPFD (100, 200, and 400 μmol·m-2·s-1) on growth, and macro- and micronutrient use efficiency of three genetically contrasting cacao genotypes (CCN 51, VB 1117 and NO 81). Intraspecific variations were observed in cacao genotypes for growth parameters at ambient to elevated carbon dioxide and low to adequate levels of PPFD. With the exceptions of total root length and leaf area, irrespective of carbon dioxide and PPFD levels, all three genotypes showed significant differences in all the growth parameters. For all the cacao genotypes, increasing PPFD from 100 to 400 μmol·m-2·s-1 and carbon dioxide from 400 to 700 μmol·mol-1

虽然现代南极主体冰盖是在始新世末-早渐新世建立的，但南极洲的冰在相当早的时期可能就出现了，甚至发生在白垩纪温室气候时期。深海钻探计划的分析表明，白垩纪晚期广泛的海平面变化只可能由南极大陆尚广布的冰原所引起，并且在白垩纪暖期到达顶点之后的Maastrichtian期（约在71～65Ma之间）的气候变冷也足以使高纬度地区发生短期的冰川作用。
