The effects of solid state fermentation on the mineral concentrations and in sacco degradation characteristics of dry matter in two multipurpose tree leaves was investigated. Biodegraded Enterolobium cyclocarpum (EC) and Pterocarpus santalinoides (ps) leaves were previously inoculated with Aspergillus niger and incubated at 30°C for five incubation periods (0, 7, 14, 21 and 28 days). After each incubation period, samples were oven dried at 60°C, allowed to cool and ground for mineral analysis and in sacco dry matter degradability. Three fistulated West African Dwarf (WAD) rams (Ovis aries) were then used for the dry matter degradability. Five grams of each sample was emptied into nylon bag (Polymon, Switzeland) with pore size of 4 μ and effective size of 5 cm × 18 cm and incubated in the rumen of the fistulated animals for 6, 12, 24, 48, 72, and 96 h. The results showed that the mineral contents of biodegraded EC samples were affected by incubation period. Mean values of Ca, Cu, K, Na, and Zn were significantly increased (0.05), while mean values of Fe, Mg, and Mn were first reduced before significantly increasing (0.05). However, the composition of P showed significant reduction (0.05) up to day 28 where no change was observed. Mineral concentrations in biodegraded ps were also affected by incubation periods. Values of Ca, Fe, K, Mg, Mn, Na, and Zn were significantly increased (0.05). However values of Cu, and Fe only increased after day 14, while the value of P was reduced significantly over the different incubation periods. Potential degradability (PD) for biodegraded EC was highest at day 0 (50.79%) but not significantly different from potential degradability of longer incubation periods to day 28 (48.68%). ps had higher PD than EC. In spite of high PD values, ps comparatively degraded faster than EC. Effective degradability (ED) for EC was highest for day28 (36.71%) and not significantly different from days 21 (34.83%) and 7 (35.29%) but significantly dif

世界核心医学期刊文摘（儿科学分册） 2006年第9期2卷 38-39页

作者： Nwomeh B.C. Georges A.j. Groner j.I. 刘凯 Department of Pediatric Surgery Children's HospitalColumbusOH 43205United States

Background:Limitation of resident work hours has created the need to explore alternatives to surgeon presence during initial assessment and resuscitation for selected life-threat-ening injuries in children. We recently eliminated the requirement for surgeon presence during Level II alerts. The purpose of this study was to evaluate the impact of this change on patient care. Methods:A retrospective analysis of trauma alert activity was performed using data from our trauma registry. In March 2003,responsibility for level II alerts was transferred from the pediatric surgeons (pss) to the Emergency Department (ED)-physicians. We compared the activity in the 18-month period before this change (period 1; n=627) to that afterward (period 2; n=587). Outcome measures included injury severity score,emergency department length of stay,missed injuries,abdominal computed tomography use,and mortality. Data were analyzed using log-rank statistic,χ 2,or t test,where appropriate,with significance level at P jury severity score for period 1 (8.5 ± 7.3 SD) was similar to period 2 (9.0 ± 7.1 SD). When ED physicians replaced ps for Level II alerts,ED length of stay increased from 135 minutes to 165 minutes (P juries and no significant differences in the rate of mortality. Conclusions:When ED physicians replaced ps for Level II alerts,trauma room length of stay was increased,but use of abdominal imaging was decreased with no differences in rate of missed injury or mortality. Emergency Department physicians can safely replace ps during Level II alerts. These findings may be useful to institutions experiencing surgical workforce limitations for trauma alerts.

Recent results in the development of diode-driven high energy, high repetition rate, picosecond lasers, including the demonstration of a cryogenic Yb:YAG active mirror amplifier that produces 1.5 j pulses at 500 Hz repetition rate(0.75 kW average power) are reviewed. These pulses are compressed resulting in the generation of ~5 ps duration,1 j pulses with 0.5 kW average power. A full characterization of this high power cryogenic amplifier, including atwavelength interferometry of the active region under >1 kW average power pump conditions, is presented. An initial demonstration of operation at 1 kW average power(1 j, 1 k Hz) is reported.

与行播F3及以后各代品系间的选择相比,对谷类作物及其它自花授粉作物极为有效的系谱选择法（ps）的唯一严重缺点是F2代单株间选择效率低.Valentine（1979）提出,根据遗传力较高的产量构成因素如每穗粒数和千粒重进行间接选择可提高春大麦产量单株选择的效率,且借助形态特征的图解和丰富的育种经验可提高单株产量构成因素的目测效率（Ismail等,1984）.
