2015年的前6个月,中国的工程机械市场大幅下滑,年比销售额下降了39%。几乎所有部门的产品都继续低迷,土方机械受到的冲击特别严重。低迷的严重程度比年初行业预计要大得多。市场销售量只有两年前的50%,行业的信心下降到有史以来最低。现有设备的利用率大约在25-40%之间,大大影响了业主收回投资。对价格敏感的用户倾向于购买二手设备或租赁设备来增加设备的数量,这样可以降低财务风险和使用设备的灵活性。

2009年11月10日,美国众议院73名议员联合向白宫发了一封信,力促总统奥巴马在他的2011预算中为国际计划生育(family planning)增加10亿美元。鼓吹计划生育并不少见,值得注意的倒是这封信,信中称"气候变化"是要求低生育率的原因。"计划生育,"信中说,"应该被囊括到关于对气候变化进化缓解与适应的更大的策略中。较低的人口增长率将使得减少全球温室气体排放的目标更容易达到。"

本文利用时间分辨光谱技术在选定的溶剂体系中,探究对羟基进行保护的Anthraquinon-2-ylmethoxycarbonyl（Aqmoc）光敏保护物1和2的光物理和光化学性质。研究发现,在乙腈中,化合物1和2生成了其三重态物种;在异丙醇中,通过氢原子转移（HAT）生成了羰基自由基物种;在四氢呋喃中,化合物1和2也发生了HAT过程但比在异丙醇中的反应效率低;在四氢呋喃-水溶液中,化合物1和2通过质子耦合电子转移（PCET）生成羰基自由基物种是光脱保护反应的先驱物并且进一步形成二羟基蒽醌物种。1和2的光脱保护过程伴随着脱二氧化碳。这项工作的研究推进了Aqmoc作为光敏保护基的应用尤其在生物领域方面。

World Journal of Otorhinolaryngology-Head and Neck Surgery 2016年第1期2卷 -页

作者： Krupa R. Patel david J. phillips Jason M. Leibowitz Theresa Scognamiglio Victoria E. Banuchi William I. Kuhel david I. Kutler Marc A. Cohen Weill Cornell Medical College New York NY 10065 USA Department of 0tolaryngology-Head and Neck Surgery New York Presbyterian Hospital/Weill Cornell Medical Center New York NY 10065 USA Department of 0tolaryngology-Head and Neck Surgery University of Miami Miami FL 33136 USA Department of Pathology&Laboratory Medicine New York Presbyterian Hospital/Weill Cornell Medical Center New York NY 10065 USA

Objective:To assess the characteristics and quality of cost utility analyses (CUA) related to otolaryngology within the CEA registry and to summarize their collective results. Methods:All cost-utility analyses published between 1976 and 2011 contained in the Cost-Effectiveness Analysis Registry (CEA Registry) were evaluated. Topics that fall within the care of an otolaryngologist were included in the review regardless of the presence of an otolaryn-gologist author. Potential associations between various study characteristics and CEA registry quality scores were evaluated using the Pearson product moment correlation coefficient. Results:Sixty-one of 2913 (2.1%) total CUA publications screened were related to otolaryn-gology. Eighteen of 61 (29.5%) publications included an otolaryngologist as an author. Fourteen studies agreed on the cost effectiveness of at least unilateral cochlear implantation and six of seven (85.7%) studies demonstrated the cost effectiveness of continuous positive airway pres-sure (CPAP) for obstructive sleep apnea (OSA). Forty-six percent (28 of 61) of all manuscripts were published between 2008 and 2011. A more recent publication year was associated with a higher CEA registry quality score while the presence of an otolaryngologist author and journal impact factor had no significant correlation with the quality of the CUA. Conclusion:Based on current evidence in the CEA registry, unilateral cochlear implantation for hearing loss and CPAP for OSA are both cost-effective therapeutic interventions. Although CUAs in otolaryngology have increased in quantity and improved in quality in more recent years, there is a relative lack of CUAs in otolaryngology in comparison to other subspecialties.
