Economic potentials of industrial rocks and minerals in the Azraq basin,NE Jordan

The Azraq basin (the Badia region in NE-Jordan) is rich in its industrial rocks and minerals. Most of the commodities are concentrated in one area, which is the Azraq depression (El-Qa’). The climatic changes (wet and dry) of Azraq closed lake contributed in the formation of industrial rocks and minerals in the El-Qa’. Basalt, pyroclastics, zeolites, diatomaceous earth, bentonite, palgorskite, porcelanite, saline brines, chalk, limestone, and gypsum are the potential industrial commodities. The basaltic rocks are of high alkalis content and good homogeneity and are of good potential use in constructions and cast basalt. The scoriaceous pyroclastic material proved to be of excellent properties for use as lightweight aggregates, cultivation purposes, and for the production of pozzolanic cement. Smectite-rich beds (bentonite) from Ein El Badia could be used as binder, absorbent, and additives for feeding farm animals. Palygorskite is potential for use in drilling mud, paint, pharmaceuticals, and as a filtering medium. The diatomaceous earth deposits are Moler type and could be used as filter aid and absorbent. Zeolites are efficient for agricultural purposes, animal waste, and wastewater treatment plants. Saline brine is exploited in the Azraq mudflat area for table salt. Porcelanite could be used as an absorbent of hazardous elements, abrasive, and filler. The softness and high purity of chalk enable its use as filler and in the lime production. The large limestone concretions are of high quality for use as a building stone. Gypsum (gypcrete) could be used after the removal of the undesired chert impurities. The Badia region is a highly potential area for future exploration and mining industry in a manner that achieves the required outcomes and minimizes impacts on ecosystems.     

Krieger’s conceptualization and measurement of discrimination and internalized oppression in studies of adverse health outcomes

Embodiment is a central concept in Krieger’s ecosocial theory, and is said to be of relevance to the understanding of the relationship between social conditions and a variety of adverse health outcomes. The most detailed empirical investigation of this in Krieger’s work is to be found in her studies of the relationship between racial discrimination and high blood pressure. Of especial relevance here is the idea of internalized oppression which is said to explain the observed association between self-reports of no racial discrimination and increased levels of blood pressure among working-class African Americans. Here we critically examine the empirical evidence pertaining to internalized oppression. Specifically, we focus on the measurement of the construct and the quality of the empirical evidence that has been presented in support of the hypothesis that there is an association between internalized oppression and adverse health outcomes. We argue that the validity of the concept has yet to be established and that the available data linking it to poor health outcomes are open to alternative explanations, notably measurement error and misclassification.

基于升降轨ASAR的于田Ms 7.3级地震同震形变场信息提取与分析

升降轨干涉测量可以更好地反映地震同震形变场特征。利用欧空局ASAR数据通过二轨法差分干涉测量提取了新疆于田县Ms 7.3级地震升降轨同震形变场信息。结果显示:升轨同震形变场最大视线向(LOS)隆升形变量约+13.3 cm,沉降形变量约-83.9 cm;降轨同震形变场最大LOS向隆升形变量约+36.5 cm,沉降形变量约-66.5 cm。于田地震以NNE向正断层破裂为主,并伴随左旋走滑运动,西北盘为正断层破裂的上盘(沉降盘),东南盘为正断层破裂的下盘(隆升盘)。升降轨同震形变场存在一定差异,但其变化趋势与特征非常相似,其差异主要是由于两种不同观测模式所造成的。     

广西田阳县那赖旧石器遗址发现的石制品和玻璃陨石

对广西田阳县那赖旧石器遗址进行实地调查,在百色盆地右江第Ⅳ级阶地的网纹红土中发现了一件玻璃陨石和大量的旧石器（包括12件手斧）。玻璃陨石的特征表明其为原地埋藏,未经后期流水作用搬运。玻璃陨石和石器之间的关系进一步证实,百色盆地第Ⅳ级阶地中保存的玻璃陨石可以代表手斧的埋藏年代。那赖遗址的石制品组合与百色盆地其他遗址的类似。通过与世界上其他阿舍利手斧在形态上和技艺上对比表明,该遗址手斧代表了早中更新世之交东亚的阿舍利技术特点。

     

Si^4＋及过渡金属离子在蓝宝石呈色中的作用——数学分析法在离子致色研究中的应用

理想晶体（包括蓝宝石）的颜色与占据其晶格的微量过渡金属元素的种类及含量有直接的关系。玄武岩产状的蓝宝石中含有多种微量元素，这些元素是蓝宝石致色的直接因素。本文通过研究发现，每种微量元素均对可见光的特定波段产生不同程度的吸收，其中，Fe^3 ,Si^4 是使蓝宝石呈现蓝色的主要离子，Cr^3 离子可使蓝宝石呈橙和绿色，Mn^4 离子可使蓝宝石呈黄色，Co^2 离子也可使蓝宝石呈蓝色。本文还做出了蓝宝石中每种微量元素对可见光的特征吸收图即波长－吸收系数图，与分子轨道理论值吻合，把蓝宝石中各离子对可见光的吸收位置和相对吸收强度统一起来。     

ASCA observations of the Galactic superluminal sources GRO J1655–40 and GRS 1915+105

We summarize the ASCA observations of the two Galactic superluminal sources GRO J1655–40 and GRS 1915+105, focusing on theabsorption line features.The high spectroscopic capability of ASCA enabled us to detectiron-K absorption line features from both objects. This is direct evidence for the presence of highly ionized plasma in a non-spherical configuration around a black hole, and is considered to be a unique signature of superluminal jet systems. The candidate of the line-absorber would be a part of an accretion disk at a distance of 10^9-11 cm from the central X-ray source.

Improvement of user’s accuracy through classification of principal component images and stacked temporal images

The classification accuracy of the various categories on the classified remotely sensed images are usually evaluated by two different measures of accuracy, namely, producer’s accuracy (PA) and user’s accuracy (UA). The PA of a category indicates to what extent the reference pixels of the category are correctly classified, whereas the UA of a category represents to what extent the other categories are less misclassified into the category in question. Therefore, the UA of the various categories determines the reliability of their interpretation on the classified image and is more important to the analyst than the PA. The present investigation has been performed in order to determine if there occurs improvement in the UA of the various categories on the classified image of the principal components of the original bands and on the classified image of the stacked image of two different years. We performed the analyses using the IRS LISS III images of two different years, i.e., 1996 and 2009, that represent the different magnitude of urbanization and the stacked image of these two years pertaining to Ranchi area, Jharkhand, India, with a view to assessing the impacts of urbanization on the UA of the different categories. The results of the investigation demonstrated that there occurs significant improvement in the UA of the impervious categories in the classified image of the stacked image, which is attributable to the aggregation of the spectral information from twice the number of bands from two different years. On the other hand, the classified image of the principal components did not show any improvement in the UA as compared to the original images.     

Application of a distributed erosion model for the assessment of spatial erosion patterns in the Lushi catchment,China

A grid-based erosion model is developed by integrating the distributed hydrological model, BTOPMC, with the modified USLE to estimate soil erosion and sediment outflow during single storms. The possible sheet, rill, channel erosion types, and sediment transport processes are considered within each grid under the model structure. Instead of representing the sheet erosion and rill erosion separately, the classic USLE method is modified to simulate the lumped sheet–rill erosion during storms. In the modification, the runoff ratio and a relevant correction coefficient are brought into the R-factor which improves the model’s applicability in predicting erosion during single storms. Instead of representing a grid with a unique erosion type, a channel component is assumed to exist in each grid, and its width varies with the upstream contributing area of the grid. This assumption avoids the problems that are caused by the difference between the channel widths in the upstream area and the downstream area if the grid is simply recognized as a channel grid. It also enables the model to be applicable in simulating soil erosion and sediment outflow from a large catchment. Through a case study in the Lushi catchment, China, the results show an overall satisfactory accuracy for the selected events. Moreover, by analyzing the spatial distribution of soil erosion or deposition, the erosion-prone areas are identified for the prioritization purpose.
