The Early Permian (Shansi + Lower Shihhotse Formations) palynofloras of Longshoushan are dominated by Cathaysian-Euramerican common forms, mainly composed of pteridophytic and pteridospermous spores. But up to the Lower Shihhotse Formation, gymnosperms greatly developed, and they possibly already dominated the vegetation in the Upper Shihhotse Formation; while in the late Late Permian, they indicate a strong colour of Subangara area. In other words, during the whole Permian, the Cathaysian flora had a history from prosperity to decline, and Subangara plants might have had a reverse tendency there.

Small-scale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health and environmental problems. However, a mercury-free method described below has proved to extract up to twice as much gold without need of investment in new processing equipment and without longer processing time. The method has successfully been tested in the Philippines, Indonesia, Tanzania, Bolivia and Zimbabwe.

How to Mitigate Mercury Pollution in Tanzania

作者： Mauri Saksala Tamglass Ltd.oy

Present architectural concepts request its use to create more visual and aesthetic designs in buildings, to give new shapes and appearances. The penetration of its use varies greatly between Europe, the Far East and the Americas, due to the different technology levels in these markets. This article takes a look at how the use of bent, tempered glass is, however, continuously on the increase.

Mercury pollution from small-scale gold mining poses a serious threat to the global and local environment. Recycling of mercury for small-scale miners has been introduced over decades in Tanzania with little success. The environmentally benign borax gold extraction method invented more than thirty years ago in the Philippines and presently used by more than thirty thousand Philippine miners has proved to work on the gold ores in Chunya and Singida gold districts of Tanzania. By using borax instead of mercury the miners reduce the risk of polluting the environment and spoil their health for generations. The most convincing argument for the miners to change to borax is that they can increase their gold recovery up to fifty percent without need for investing in new equipment and without much more work on processing.

Background: The burden of stroke is very high in sub-Saharan Africa. The identification of the factors influencing poor outcome can help to reduce this burden. Objective: To study factors influencing the prognosis of stroke at Parakou. Methods: It was a prospective study conducted over two periods: inclusion period between 1st January and 30 June 2013;monitoring period of survivors between 1st July and 30 September. All consecutive patients admitted in the hospitals for stroke in the study period were included. The functional outcomes were assessed by the RANKIN scale (RANKIN > 2). Epi-info version 7 and SPSS version 16 were used for the statistical analyses. Results: We recruited 85 patients;mean age was 52 ± 15 years. The housewives and the unschooled represented respectively 33% and 65%. The mortality rates at 1 and 3 month were respectively 27% and 32%. Factors associated with mortality were female gender, stroke severity, disorders of consciousness, hyperthermia and hyperglycemia at admission, overweight, pneumonia, anemia, hyperleucocytosis, higher total and LDL serum cholesterol levels at 1 month;housewife status and pneumonia were associated at 3 month. 47% of survivors were independent at 1 month. Stroke severity and length of hospital stay were associated with disability at 1 month whereas previous stroke and disability history, stroke severity, weight and length of hospital stay were related with 3 month poor functional outcome. Conclusion: This study showed the poor outcome of stroke patients in Parakou which were influenced by many factors. Taking account of these factors in the strategies of care in the acute phase may improve the prognosis of stroke patients.

This thorough review explores the complexities of geotechnical engineering, emphasizing soil-structure interaction (SSI). The investigation centers on sheet pile design, examining two primary methodologies: Limit Equilibrium Methods (LEM) and Soil-Structure Interaction Methods (SSIM). While LEM methods, grounded in classical principles, provide valuable insights for preliminary design considerations, they may encounter limitations in addressing real-world complexities. In contrast, SSIM methods, including the SSI-SR approach, introduce precision and depth to the field. By employing numerical techniques such as Finite Element (FE) and Finite Difference (FD) analyses, these methods enable engineers to navigate the dynamics of soil-structure interaction. The exploration extends to SSI-FE, highlighting its essential role in civil engineering. By integrating Finite Element analysis with considerations for soil-structure interaction, the SSI-FE method offers a holistic understanding of how structures dynamically interact with their geotechnical environment. Throughout this exploration, the study dissects critical components governing SSIM methods, providing engineers with tools to navigate the intricate landscape of geotechnical design. The study acknowledges the significance of the Mohr-Coulomb constitutive model while recognizing its limitations, and guiding practitioners toward informed decision-making in geotechnical analyses. As the article concludes, it underscores the importance of continuous learning and innovation for the future of geotechnical engineering. With advancing technology and an evolving understanding of soil-structure interaction, the study remains committed to ensuring the safety, stability, and efficiency of geotechnical structures through cutting-edge design and analysis techniques.
