Geodynamic Development of Eurasian Active Margin during Closing of Thetys Ocean, Depending on the Scale of Mantle-Crustal Sources Influence at Pre- and Post-collision Settings, Controlled by Geological and Geochemical Indicators

Phanerozoic geodynamic evolution development of Tethys Ocean,its collision and closing,revealed at the Eurasian active margin in pre-and post-collision stages during convergence of Afro-Arabian and Eurasian continents.Subduction of oceanic slab under continental margin revealed in steady state subduction and steepening of subducting slab provoked the incursion of mantle diapir.The steady state subduction is related with island arc setting whereas steepening provoked incursion of mantle diaper interarc-backarc and minor ocean settings.They are controlled by geological indicators—volcagenic,petrochemical,geochemical,tectonic and metallogenic.Each of them is determined by scale of mantle-crustal influence,controlled by intensity and level of mantle diapir incursion in the crust rising from interarc-backarc to minor oceanic setting.The island arc setting is characterized by blocking,which as others by extension of rifting(interarc-backarc)caused spreading out from zone of volcanic activity and mineralization sialic crusts,whereas minor ocean setting caused by spreading out from zone of volcanic activity and mineralization sialic and basaltic crusts.So mantle crustal influence rising from island arc to minor ocean settings controlled type of volcanism and mineralization in pre-collision development.At the closing of ocean occurred the precollision setting which is transferred in post-collision revealed in orogenesis.It is divided in two stages.The first initial stage occurred in penetration hot fluids from the mantle in sialic crust smelted from in granitoid melt and leached the gold and trace melts Sb,W,Mg and Hg from sialic crust.The latter are geochemical indicators of post-collision setting.The second final stage revealed in shoshonite-basalt volcanism activity occurred with penetrated mantle material into deep volcanic chambers and characterized with increasing of mantle influence than initial stage of post-collision activity.

2-Tuple and Rough Set Based Reduction Model for Multi-sensory Evaluation Indicators

In order to lessen adverse influences of excessive evaluative indicators of the initial set in multi-sensory evaluation,a2-tuple and rough set based reduction model is built to simplify the initial set of evaluative indicators. In the model,a great variety of descriptive forms of the multi-sensory evaluation are also taken into consideration. As a result,the method proves effective in reducing redundant indexes and minimizing index overlaps without compromising the integrity of the evaluation system. By applying the model in a multi-sensory evaluation involving community public information service facilities,the research shows that the results are satisfactory when using genetic algorithm optimized BP neural network as a calculation tool. It shows that using the reduced and simplified set of indicators has a better predication performance than the initial set,and 2-tuple and rough set based model offers an efficient way to reduce indicator redundancy and improves prediction capability of the evaluation model.

Consistency of Nursing Directors, Nursing Supervisors, and Nursing Quality Specialists’ Perception about Nursing-Sensitive Indicators in Acute Care Settings

Introduction: Nursing-Sensitive Indicators (NSIs) is a critical concept for the advancement of the nursing profession. However, different managerial positions may have a different perspective on the appropriate NSIs that should be used in hospitals for the monitoring of nursing care quality. This study aims to find if there is a difference between three groups of nursing managerial positions on the appropriateness of NSIs for the monitoring of nursing care quality. Methods: Descriptive cross-sectional approach was employed to evaluate if there is a difference among the three managerial groups in their evaluation for the appropriateness of using a cluster of NSIs in acute care settings. The study was conducted in Jordan between February and March 2020. Result: The study participants were 60 nurses from different managerial positions. The mean scores of the participants were: directors of nursing (200.6), nursing supervisors (199.1), and nursing quality specialists (198.62). The findings revealed no statistical difference between the three groups of their evaluation of the appropriateness of the NSIs. Conclusion: Standardizing the nursing mangers perspectives of NSIs may advance utilization of the NSIs for the monitoring and reporting of nursing care quality. Implications for Nursing Management: Consistent understanding of the measures that can be used to monitor quality of nursing care can establish the foundation for quality measurement and quality improvement in acute care settings.

The 144–140 Ma Mafic Dykes in North China and Northeast China Indicating Regional Extensional Tectonic Setting

Objective Previous studies indicate that the North China Craton（NCC）had undergone the loss of thickened lithosphere and fundamental change of physical and chemical property of lithospheric mantle（the destruction of NCC）during the Mesozoic.The peak period of the destruction of NCC is estimated to be 130 Ma,accompanied by widespread metamorphic core complex,rift basins,A-type granites and mafic dykes. However, it remains greatly controversial on the tectonic setting of NCC in the pre- 130Ma.

The Characteristics of the Hydrothermal Exhalative Dolostone of Lucaogou Formation in Santanghu basin and its Geology Setting Indication

The NW-SE trending Santanghu basin is located in Xinjiang,NW China,between Tianshan Mountains and Altai Mountains.The tectonic evolution history of north Xinjiang has long been debated,especially the question when did that area began its intraplate rift evolution stage.This abstract discusses the features and possible origin of the hydrothermal exhalative dolostone of Lucaogou Formation in Santanghu basin,aiming to provide relevant information about this question.The target dolostone are characterized by extreme thin lamina of 0.3cm–1 cm thick.Dolomite,ankerite,potassium feldspar and analcite are dominant composition.Most dolomite is poor crystallized and is in anhedral or subhedral shapes.Ankerite is generally porphyritic,few is in irregular shapes.It has to be noted that the porphyritic ankerite commonly develop zonal textures characterized by rings with various Fe O content.Potassium feldspar and analcite（<50%）are commonly observed in dolostones.Thin sections show some analcite is tetragonal trisoctahedron with harbour–like corrosion rims.Besides,few fragments of carbonatite rocks are observed in Lucaogou Formation and they perform intermittent or scattered distribution in rock layers.Previous work done by our study team showsδ13C PDB values are 4.8‰;1.4‰,6.93‰on average.Theδ18 O PDB values are between-5‰;21.1‰,-10.94‰on average.Paleosalinity calculated byδ13C andδ18 O is between 128.35 and 136.81,134.42 on average.Sr content of dolostones in study area reaches to164×10-6;37×10-6（379.1×10-6 on average）,most dolostone in target area are between 0.70457;.706194, average at 0.705360.Considering either accompanying residual tuff or residual leucite is found via electron probe,this indicates the analcite may derive form analcime phonolite.Furthermore,fragments of carbonatite rocks proves mantle-derived magmatism exist.The rapid variation ofδ18 O indicates multiple interactions of hydrothermal fluids with lake water during Lucaogou sedimentary period.87Sr/86Sr values are much lower than that of crustal silica rocks while are more close to mantle derived rocks,which indicates diagenetic hydrothermal fluid is mantle-origin.It has been reported that dolostone does not intergrow with iron-rich dolostone in study area.According to the latest X diffraction results of cores,iron-rich dolostone distributes rather locally.Given that ankerite commonly develop zonal textures characterized by various Fe O content,we confirm it is due to multiple hydrothermal fluids activities in different hydrothermal vents.There should be abundant hydrothermal vents during Lucaogou period.Deep faults and its relevant fractures built plenty paths for mantle-origin hydrothermal fluids to run up.Different vents owned various fluid properties,so did relevant sedimentation products.Hence we inclined to believe Santanghu basin was at intraplate rift evolution stage,under regional extension condition in late Carboniferous.During early-mid Permian the basin was a starved,deep lacustrine intracontinental rift basin.Accordingly,in northern Xinjiang,ocean basin may close in late Carboniferous and started continental sedimentary development in early Permian.

Clinical Features and Haematological Indices of Neonatal Septicaemia in Poor Resource Setting

Background: The burden of neonatal septicaemia has remained high worldwide and even more severe in the developing countries like ours. Clinical manifestation is variable and non-specific thereby resulting in delay in diagnosis. Blood culture which is the gold standard for diagnosis of neonatal septicaemia (NNS) has many drawbacks due to long waiting time for culture process, low yield, improper inoculation adding to the problem of late diagnosis. Haematological parameters have been utilized in rapid and early diagnosis of NNS and prompt treatment thus circumventing problems associated with drawbacks in blood culture. Objective: The study was to identify the common clinical features of neonatal septicaemia and haematological indices that were commonly utilized in rapid diagnosis of NNS, and also to determine their sensitivity, specificity, positive predictive and negative predictive value. Materials and Methods: The study was prospective and neonates that had clinical features suggestive of neonatal septicaemia were enrolled consecutively into the study. The patients were appropriately investigated including blood cultures, CSF cultures and urine among others, also blood sample for packed cell volume (PCV), total white cell count (TWBC), absolute neutrophil count (ANC), absolute platelet count (APC). Immature to mature neutrophil ratio (I/MNR), immature to total neutrophil ratio (I/TNR) and micro-ESR (erythrocyte sedimentation rate) was also done and analyzed. Results: The common clinical symptoms were fever 39.5%, poor feeding 33.6%, excessive cry 38.7%, difficulty in breathing 50.0%, yellowish skin 26.9%, while the common physical signs were hyper/hypothermia 41.1%, tachypnoea 41.2%, septic umbilical stump 64.0%, hepatomegally 37.3% and convulsions 42.0%. Blood culture yield was positive in 41.82% and mortality was as high as 28.00%, the incidence of NNS was 5.9/1000 live births. The haematological parameters as marker of NNS PCV, TWBC, ANC, APC, I/MNR, I/TNR and micro-ESR individually were statistically significant (P < 0.05), also their individual sensitivity, specificity, positive and negative predictive values were highly associated with neonatal septicaemia. However, when they were tested in combinations these markers of neonatal septicaemia had low sensitivity, specificity and their predictive values were weak in excluding NNS. Conclusions: The need for early and rapid diagnosis of NNS is pertinent, culturing of the appropriate specimens remains the only way to identify the aetiological organisms, but is associated with delay. Haematological indices are excellent markers of NNS and analysis is rapid and can easily be done in our laboratory settings, and when utilized efficiently, it would circumvent the delay associated with blood culture for long waiting period for the result, thereby reducing morbidity and mortality.

基于最小数据集的黔西南州烟田土壤质量评价

为明确贵州省黔西南州烤烟种植区土壤质量特征,选取51个代表性土壤样点,研究其表层(0~10 cm)和亚表层(10~20 cm)土壤的理化特征及生物学性状,同时基于主成分分析(PCA)建立最小数据集(MDS),评估不同烟草连作年限(Y1:0~10 a;Y2:10~20 a;Y3:20 a以上)对植烟土壤质量指数(SQI)的影响。主成分分析结果表明,MDS由土壤有机质、全氮、全磷、碱解氮、速效钾含量及脲酶活性6项指标构成。全数据集(TDS)的土壤质量指数(TDS-SQI,均值0.589)与MDS-SQI(均值0.581)呈显著正相关关系(R^(2)=0.993,P<0.01),表明MDS和TDS均可用于解释土壤质量特征。此外,MDS-SQI与烤烟株高、叶长均呈极显著正相关关系,说明土壤MDS-SQI越大的点位附近烤烟生长状况越好,再次表明MDS相关指标具有较好的代表性。不同土层(0~10、10~20 cm)间SQI差异不显著;Y3(20 a以上)的烟田土壤SQI低于Y2(10~20 a)和Y1(0~10 a),Y1与Y3土壤SQI值差异达显著水平(P<0.05)。综上,土壤有机质、全氮、全磷、碱解氮、速效钾含量及脲酶活性6项指标可有效评估黔西南州烟田土壤质量;烟草长期连作会造成土壤质量下降。

Evaluation of the maintenance window scheme using fuzzy soft set theory

The maintenance window scheme(MWS) is one of the most important railway transportation organizational plans and plays an important role in ensuring railway operational safety. However, MWS setting is a very complicated process, and most countries currently do so with the help of a computer-aided decision system. In general, a decision system can generate multiple alternatives for MWS within an acceptable time. Therefore, how to choose the best option from the alternatives is a vital decision. This paper presents a novel framework for MWS evaluation based on the Chinese railway system. Specifically, the requirements of each department related to MWS setting are analysed, and we construct an evaluation indicator system for MWS based on the preferences of different departments. Then, we apply the fuzzy soft set theory to MWS evaluation, a method that not only effectively deals with evaluation of uncertain information, but also gives flexibility for experts to input their subjective judgment.Additionally, using the ‘‘AND’’ operation of soft set theory allows combing evaluation information from multiple evaluators to give comprehensive results. Finally, a case study illustrates the proposed framework, showing that the proposed evaluation indicator system and evaluation method are effective and practical.
