Limestones have been one of the major economic sources in state’s economy and becoming more and more important in recent years. They are mainly exploited for crushed stone, dimension stone and micronized calcite production including lab-grade CaO with high purity. Although some of the applications require fairly simple value-adding processes such as crushing and/or sizing, some may require rather complicated processes such as calcination and coating.

Marajó, located in the lower Amazon, Brazil, is one of the largest river islands in the world. Most of the island is subject to tidal or seasonal flooding. Despite its historical, cultural and geographical importance, Marajó Island remains relatively less investigated in terms of mammal diversity, ecology and community structure than the rest of the Amazon. This scenario has motivated the presentation of this list of land mammals of eastern Marajó Island. Two field surveys were conducted in the course of 7-11 December 2012 and 17-25 October 2013 in Jaranduba, Dunas and Ribanceira Farms, northeast portions of Marajó Island. A total of 23 large and medium-sized land mammal species were recorded in the study area. These farms host a representative mammal community of northeastern Marajó, an area lacking previous faunal studies. Human pressure over centuries has deeply modified the environment in Marajó. Therefore, striking evidence of a long human-populated past in this island is in accordance to many other sites throughout the Amazon plain. The result of a land mammal survey in northeastern Marajó is a clear evidence of past and present human interference in the island. Even though Marajó Island has exalted mammal diversity, it will be much higher if long-term studies are effectively implemented.

通过比较中国四川黄龙、中国云南白水台、土耳其帕穆克卡莱棉花堡三地钙华景观的基本环境地质特征、钙华景观水化学、钙华沉积生物因素的差异性,探讨了土耳其棉花堡钙华退化缓慢的影响因素。对比发现,棉花堡景区藻类约为38种,种类单一,植被覆盖率较低,沉积主要受物理化学因素控制,沉积速率较快,多形成较好的层状结构,杂质少,且原生孔隙度较低,结构致密,结晶度较高,不易坍塌损坏;黄龙和白水台景区藻类分别为86种、196种,种类多样,且植被覆盖率皆高达80%以上,沉积主控于化学和生物因素,沉积速率较慢,结构呈多孔疏松状或多孔珊瑚状,原生孔隙度普遍较高,易退化。此外,棉花堡钙华景区泉水各离子含量均高于黄龙和白水台景区,尤其是Ca2+和HCO3,这能有效促进CaCO3的沉积。

首先根据量纲分析建立一个描述可溶性物质在淹没水跃中扩散的数学模型,然后确定底部糙率不变或可变的情况下,各种因素对断面平均浓度的影响。通过试验在固定下游无量纲因数,改变上游无量纲因数,在一个恒定时间内测量断面的平均浓度情况并研究无量纲纵向扩散系数与其它无量纲因素的关系。还研究了起始浓度,最大断面浓度,纵向距离和淹没水跃长度之间的关系。

联合收割机的重要性在于粮食和豆类作物直接影响生产经济。另一方面,它也形成了农业机械领域的一个重要分支。联合收割机在运行时,存在许多未知的约束条件,包括脱粒机中产生的噪声和振动。该研究旨在利用传感器分析传统联合收割机的噪音与振动。在凹面的两侧分别安装了两个加速度计,再用两个麦克风记录脱粒过程中的噪音。结果表明,机械转速(3.5 km/h、4.5 km/h和5.5 km/h)和转子转速(950 r/min、850 r/min和950 r/min)对左右加速度计在X、Y和Z方向上的平均量程值有显著影响。机器速度和转子速度对左右麦克风的平均范围值影响不大。

The G ksun Ophiolites in Do an ehir area (Malatya-Southern Turkey) contain corundum mineralizations with significant gem-quality (ruby). Modal mineralogical composition of ruby-bearing rocks consists of hornblende (65%-70 %), plagioclase (20%-25%), green garnet (4%-5 %), ruby (2%-3%), and opaque minerals (<1%). Although ruby shows varying colors in the groundmass, it is generally colorless and rarely very pale pink and has high relief. It has no cleavage but rotund fractures. It has highest interference colors and twinning in some poly-prismatic crystals under the microscope. Crystal sizes range from 2x10 mm up to 30x50 mm. The most remarkable properties are red to pink in color, low to medium transparency, medium to big crystal sizes, lamellar and deformation twinning, secondary liquid feathers, hollow tubes, mineral inclusions, asterism, high birefringence and refractive indices and specific gravity. Rubies show crimson red cathodoluminescence colors activated by Cr3+ in the crystal structure, which is confirmed by the Electron Probe Microanalyses (EPMA). Tectonic setting, geological environment, petrographical, mineralogical, geochemical and gemological characteristics of rubies suggest that the Do an ehir ruby mineralization can be classified into the amphibolite-hosted type of corundum deposits of Tanzania.

器官移植 2010年第3期1卷 158-165页

目的探讨体外膜肺氧合(extracorporeal membrane oxygenation,ECMO)用于长时间冷缺血(long cold ischemic time,LCIT)供心心脏移植术的临床疗效。方法 2005年2月至2009年4月,11例患者[ECMO环路(intraoperative ECMO,i-ECMO)组]接受LCIT超过7 h的供心移植,手术采用i-ECMO进行心肺分流术,术毕直接转为ECMO辅助。同期有11例患者[心肺分流术(stand-ard cardiopulmonary bypass,s-CPB)组,s-CPB组]行冷缺血少于7 h的心脏移植手术,术中常规s-CPB,术后接受了ECMO辅助。比较两组的ECMO的总体撤机率、ICU停留时间、浓缩红细胞输注量、左心室射血分数(LVEF)、住院费用、围手术期生存率、术后1年生存率,并了解ECMO相关并发症。结果 i-ECMO组和s-CPB组供心缺血时间分别为422～485(平均448)min、110～400(平均218)min,两组间比较差异有统计学意义(P0.05)。i-ECMO组的ICU停留时间、浓缩红细胞输注量以及住院花费均显著低于对s-CPB组(均为P0.05)。ECMO相关并发症及处理:5例患者(23%)因低心排量而应用了主动脉内球囊反搏(IABP),其中3例为成功撤离ECMO的病人,2例为未能撤离ECMO者;6例(27%)患者由于肾功能不全接受了持续肾替代治疗(CRRT),其中2例为成功撤离ECMO,4例为未能撤离ECMO者。结论用边缘供心进行心脏移植术时,术中利用i-ECMO、术毕转为ECMO辅助可以为LCIT的供心提供早期、持续和有效的循环支持,从而在相当程度上改善此类边缘供心的移植成功率。同时,该研究方法还具有ICU停留时间短,浓缩红细胞输注量低和显著节省费用的优点。
