分析了两个咖啡品种及两个相关杂种的五个样本中咖啡豆和果肉的低分子量酚化合物和咖啡因含量。咖啡豆成份与以前报道的结果一致。果肉含有与咖啡豆成份相同的咖啡酰奎尼酸、阿魏酰奎尼酸、双咖啡酰奎尼酸,但含量较少。中粒种咖啡果肉中未观测到咖啡阿魏酰奎尼酸。中粒种咖啡果肉的咖啡因含量比两个小粒种咖啡果肉的低,而咖啡豆的情形却相反。从果肉样品中分离和鉴定出来的主要成份是原儿茶酸。

Horseweed is traditionally considered a non-cropland weed. However, populations resistant to glyphosate have eventually become established in no-till agronomic cropping systems. Growth chamber and greenhouse experiments were conducted to compare selected biological and physiological parameters of glyphosate-resistant (GR) and -susceptible (GS) horseweed biotypes from Mississippi with a broader goal of fitness characterization in these biotypes. Vegetative growth parameters (number of leaves, rosette diameter and area, shoot and root fresh weights) were recorded weekly from 5 to 11 wk after emergence and reproductive attributes [days to bolting (production of a flowering stalk) and flowering] and senescence were measured for both GR and GS biotypes under high (24°C/20°C) and low (18°C/12°C) temperature regimes, both with a 13-h light period. Physiological traits such as net photosynthesis, phenolic content, and cell membrane thermostability, all in the presence and absence of glyphosate, and leaf content of divalent cations such as Ca2+ and Mg2+ were assayed in the two biotypes under the high temperature regime. All horseweed vegetative growth parameters except root fresh weight were higher in the high temperature regime compared to that in low temperature regime in both biotypes. number of leaves, rosette diameter and area, shoot and root fresh weight were 40 vs. 35, 9.3 vs. 8.7 cm, 51 vs. 43 cm2, 3.7 vs. 3.2 g, and 3.5 vs. 4.2 g under high and low temperature conditions, respectively, when averaged across biotypes and weekly measurements. All growth parameters listed above were higher for the GR biotype compared to the GS biotype. number of leaves, rosette diameter and area, shoot and root fresh weight were 38 vs. 37, 9.1 vs. 8.9 cm, 50.2 vs. 44 cm2, 3.9 vs. 3.1 g, and 4.3 vs. 3.5 g for GR and GS biotypes, respectively, averaged across the temperature treatments and weekly measurements. Reproductive developmental data of these biotypes indicated that the GS biotype

Burn injuries and their treatments result in severe *** traumatic injuries that are characterized by a discrete episode of pain followed by recovery,burn-injured patients endure pain for a prolonged period that lasts through wound closure(*** pain,procedural pain,breakthrough pain,neuropathic pain and itch).Regional anesthesia,including peripheral nerve blocks and neuraxial/epidural anesthesia,offers significant benefits to a multimodal approach in pain treatment.A‘regional-first’approach to pain management can be incorporated into the workflow of burn centers through engaging regional anesthesiologists and pain medicine practitioners in the care of burn patients.A detailed understanding of peripheral nerve anatomy frames the burn clinician’s perspective when considering a peripheral nerve block/*** infra/supraclavicular nerve block provides excellent coverage for the upper extremity,while the trunk can be covered with a variety of blocks including erector spinae plane and quadratus lumborum plane *** lower extremity is targeted with fascia iliaca plane and sciatic nerve blocks for both donor and recipient *** centers that adopt regional anesthesia should be aware of potential complications and contraindications to prevent adverse events,including management of local anesthetic toxicity and epidural *** of anticoagulation around regional anesthesia placement is crucial to prevent hematoma and nerve ***,regional anesthesia can facilitate a better patient experience and allow for early therapy and mobility goals that are hallmarks of burn care and rehabilitation.

向量优化是指在一台给定机■上,对一个已知的向量计算生成最好的结果代码。本文为在控制政据 CYBER 205上运行的标量和向量源代码提出了性能分析模型。这些模型的精度对于标量代码一般是在30%以内,对于向量代码一般是在10%以内。对于一个已知的并行计算,如果编译程序可以产生一个以上的代码程序,则可以利用来自这些模型的性能估计,以便选择应当执行哪一个代码程序。把含有两个或更多个源代码版本的16个FORTRAn 核作为测试这个方法的标准检查程序。13个核正确地进行了“向量优化”。没有进行常规优化的3个核有17%的平均性能损失。用一批核作为标准检查程序表明向量优化把它的性能改进了四倍多,所有已经正确优化了的核,有98%的在程序上也可改进。
