Standard facies models to incorporate all heterogeneity levels in a reservoir model

The construction of reservoir models is frustrated by the fact that core and well cover only a fraction of the reservoir volume and it is therefore difficult to determine features like facies shape, -size, and -distribution, inter- and intra-facies boundaries and lateral trends from them. These features are, however, critical to fluid flow and they should necessarily be incorporated in the reservoir model and we therefore propose to systematically describe geometry and distribution of facies. To this end we make use of “standard facies models” that a priori contain all elements and boundaries of facies for a number of typical depositional environments.

二色桌片参酶解液对转化细胞的效应

用二色桌片参（Mensamariaintercedens）酶解液处理转化的人胚肺成纤维细胞（NLF）后，细胞生长受到显著抑制，抑制率达64．84％，光镜下细胞透光性加强，铺展较好，细胞核形更为规则，核畸形现象减少；线粒体结构趋于正常；软琼脂集落实验表明，细胞集落形成率由23ｘ10－5下降至12．5ｘ10－5，裸小鼠致瘤实验显示抑瘤率为82．39％，差异显著（p＜5％）。结果提示，二色桌片参酶解液可能逆转转化的HLF细胞的恶性表型，对其有一定的诱导分化作用。     

江苏岸外条子泥二分水滩脊的沉积特征

2000年1月16日在江苏岸外条子泥沙洲二分水滩脊选取三条断面，进行底质沉积物采样及滩面高程测量。共采集样品27个，对其用激光粒度仪进行粒度分析，发现沉积物的粒度参数、粒度组分及其分布均具有一定的变化规律，且与滩面高程变化具有很好的相关性。

Seasonal Variation in the Biomass of Marine Macrophyta from Greek Coasts

Abstract. The marine plant communities of the littoral zone in different biotopes of the Greek coasts were investigated in 1980-81. Seasonal distribution and variation of marine plant biomass were assessed. The communities of Cystoseira crinita and C. compressa were outstanding with maximum biomass during the summer months. Corallina officinalis and Pterocladia capillacea + Viva rigida communities predominated with maximum biomass in autumn and exhibited a decrease in winter, except in stressed biotopes. The species diversity and productivity of seaweeds along the Greek coasts are interpreted in relation to a number of environmental parameters.     

Application of Atomic Force Microscopy to Observation of Marine Bacteria

The atomic force microscopy (AFM) is a recently developed, bench-top instrument that can image the surface structures of biological specimens at high resolution with simultaneous measurement of their size. This paper describes the application of AFM to marine bacteria. Both natural and cultured bacteria were retained on a filter or placed on glass, washed, air-dried and observed by AFM. The instrumental condition, the choice of suitable filter, effect of fixation and filtration, comparison with epifluorescent microscopic (EFM) count, and the size and shape of bacterial cells were investigated. An Isopore filter was best for concentration and subsequent observation because of its surface flatness. Cross section images showed that both rod and coccoid cells were flattened, the former usually having a two-humped shape. Bacterial cells were differentiated from non-living particles based on their cross section shape and size. Bacterial counts by AFM and EFM showed good agreement. Although size measurement is easily done by the instrument, AFM tends to overestimate the size of microspheres. More work is thus needed on the size measurement of living organisms. Because AFM easily provides images of natural bacterial cells at high magnification, it can be used as a new tool to study the fine structures of marine bacteria. This revised version was published online in July 2006 with corrections to the Cover Date.
