The relationship between spatial patterns of macrobenthos community characteristics and environmental conditions（salinity, temperature, dissolved oxygen, organic matter content, sand, silt and clay） was investigated throughout the Gorgan Bay in June 2010. Principal components analysis（PCA） based on environmental data separated eastern and western stations. The maximum（4 500 ind./m2） and minimum（411 ind./m2） densities were observed at Stas 1 and 6, respectively. Polychaeta was the major group and Streblospio gynobranchiata was dominant species in the bay. According to Distance Based linear Models results, macrofaunal total density was correlated with silt percentage and salinity and these two factors explaining 64% of the variability while macrofaunal community structure just correlated with salinity（22% total variation）. In general, western part of the bay showed the highest number of species and biodiversity while, the highest density was found at Sta. 1 and in the middle part of the bay. Furthermore, relationship between diversity indices and macrobenthic species with measured factors is also discussed. Our results confirm the effect of salinity as an important factor on distribution of macrobenthic fauna in south Caspian brackish waters.

The main aim of this research was the experimental study at lab scale to check the absorption technology for the in situ removal of H2S from biogas during anaerobic digestion process. The reagent FeCl3 was used to check the removal efficiency of H2S produced from dairy manure during anaerobic bioconversion process. The experiments were conducted under mesophilic conditions. The composition of biogas was analyzed by gas chromatography analyzer equipped with flame photometer and thermal conductivity detectors. Experimental results under the same conditions demonstrate that high concentration of H2S in the form of FeS can be removed totally from the biogas using FeCl3 dosing with in anaerobic batch digester.

在这球发生之前的球场另一端,先是詹姆斯(leBron james)切入热火禁区准备来个帅气扣篮,不过却被移动速度愈来愈像另一尊奥尼尔的小奥尼尔(Jermaine O’Neal)挡了下来。韦德(Dwyane Wade)拿到篮板,从后场自己一条龙带球反攻,很明显,他丝毫没有想停下来的意思,直杀骑士禁区。已经退回篮下防守的瓦莱乔(Anderson Varejao)首当其冲,可怜的……呃,不对,可敬的他很勇敢地跳起来想阻止这一切,不过却像被车撞到的麦抠,整个人飞了出去摔在地下还滚了半圈。

你觉得爬到101顶楼,要花多久时间?我没爬过,所以我不知道正确答案,不过如果你问麦格雷迪(Tracy McG rady),他可能会告诉你"只要一秒钟"。比搭电梯还快。别说我唬滥,T-Mac是真的去过中国台北101,在2005年9月来台参加活动前的空当,特地要求工作人员带他上这个当时是全球最高的建筑物参观。别说我又唬滥,也就在那几个月之前,T-Mac其实已经先体验过爬上101顶端是怎样的感觉。
