In this paper, a hybrid machine learning ensemble approach namely the Rotation Forest based Radial basis Function(RFRbF) neural network is proposed for spatial prediction of landslides in part of the Himalayan area(India). The proposed approach is an integration of the Radial basis Function(RbF) neural network classifier and Rotation Forest ensemble, which are state-of-the art machine learning algorithms for classification problems. For this purpose, a spatial database of the study area was established that consists of 930 landslide locations and fifteen influencing parameters(slope angle, road density, curvature, land use, distance to road, plan curvature, lineament density, distance to lineaments, rainfall,distance to river, profile curvature, elevation, slope aspect, river density, and soil type). Using the database, training and validation datasets were generated for constructing and validating the model. Performance of the model was assessed using the Receiver Operating Characteristic(ROC) curve, area under the ROC curve(AUC), statistical analysis methods, and the Chi square test. In addition, Logistic Regression(LR), Multi-layer Perceptron neural networks(MLP neural nets), na(?)ve bayes(nb), and the hybrid model of Rotation Forest and Decision Trees(RFDT) were selected for comparison. The results show that the proposed RFRbF model has the highest prediction capability in comparison to the other models(LR, MLP neural nets, nb, and RFDT); therefore, the proposed RFRbF model is promising and should be used as an alternative technique for landslide susceptibility modeling.

In this study, a soil filled Hydraulic Tilting Flume (HTF) was used as a test plot under simulated rainfallconditions. This flume was flled with mollisols soils (sandy loam in texture) collected from tarai regionof Himalayas. The effects of root and shoot characteristics of napier grass in terms of leaf area index (LAI),shoot length (SL), number of leaves (nL), number of tillers (nT), shoot biomass (Sb), root density (RD),root length (RL), root biomass (Rb), and total biomass (Tb) were investigated on runoff and sedimentoutflow at 90, 120 and 150 days after planting (DAP). Four simulated rainfall intensities namely 4.0, 6.5,8.3 and 9.4 cm/h over three land slopes of 1, 2 and 3% were selected. Runoff samples collected fromwhole plant plot and only root plot were analyzed for runoff and sediment outflow. Findings revealedthat napier grasses were very effective to reduce runoff and sediment outflow and its efficacy increasedwith the extended growth stages. The reduction in runoff and sediment outflow at 90, 120 and 150 DAPwas obtained as 56% and 85%, 68% and 90%, and 74% and 96%, respectively, as compared to bare plotconditions. It was observed that the comparative contribution of shoots in runoff rate reduction washigher than the roots. On the contrary, the root part of the plant showed more contribution in sedimentrate reduction as compared to the shoot part. Step wise regression was attempted for the selection ofeffective input parameters to establish authentic runoff and sediment outflow models. Power form ofmultiple non-linear regression (MnLR) showed very satisfactory results for predicting runoff and sedimentoutflow with coefficient of determination (R^(2)) as 97.4% and 99.0%, respectively, root mean squareerror (RMSE) as 38.8 cc/m^(2)/min and 0.126 g/m^(2)/min, respectively, and coefficient of efficiency (CE) as93.9% and 96.7%, respectively, during testing period.

novel multistage solid-liquid circulating fluidized bed： Hydrodynamic characteristics

Particuology 2018年第3期16卷 134-142页

作者： prakash V. Chavan Manjusha A. Thombare Sandip b. bankar Dinesh V. Kalaga Veena A. Patil-Shinde Department of Chemical Engineering College of Engineering Bharati Vidyapeeth Deemed University Pune 411 043.

The present work proposes a novel radially cross-flow multistage solid-liquid circulating fluidized bed （SLCFb）. The SLCFb primarily consists of a single multistage column （having an inner diameter of 100 mm and length of 1.40 m）, which is divided into two sections wherein both the steps of utilization or loading （e.g., adsorption and catalytic reaction） and regeneration of the solid phase can be carried out simulta- neously in continuous mode. The hydrodynamic characteristics were studied using ion exchange resin as the solid phase and water as the fluidizing medium. The loading and flooding states were determined for three particle sizes; i.e,. 0.30, 0,42, and 0.61 ram. The effects of the superficial liquid velocity and solid feed rate on the solid hold-up were investigated under loading and flooding conditions. The solid hold-up increases with an increase in the solid feed rate and decreases with an increase in the superficial liquid velocity. An artificial-intelligence formalism, namely the multilayer perceptron neural network （MLPnn）, was employed for the prediction of the solid hold-up. The input space of MLPnn-based model consists of four parameters, representing operating and system parameters of the proposed SLCFb. The developed MLPnn-based model has excellent prediction accuracy and generalization capability.

Introduction: The birth of a baby is a moment of joy and celebration. However, the neonatal period is a very delicate phase of life. neonatal mortality rates remain high in low-income countries. In Guinea, after 20 years, this rate has fallen from 34.2% in 1998 to 32% in 2018. Objective: To identify the main risk factors for neonatal mortality. Methods: This was an observational, analytical case-control study, lasting 6 months from January 1 to June 30, 2019, conducted at the Institut de nutrition et de la Santé de l’Enfant (InSE) at Donka national Hospital. Results: We collected 242 cases and 242 controls, i.e. a total of 484 records. 748 patients were registered, with 32.35% deaths. 82.86% of deaths occurred in the early neonatal period. Statistical analysis revealed the main risk factors: prematurity (RQ 7.39 95% CI 3.27 - 16.61 p = 0.0000003), hypothermia (RQ 2.29 95% CI 1.51 - 3.46 p = 0.0001), acute fetal distress (RQ 2.13 95% CI 1.33 - 3.43 p = 0.0016), low birth weight (QR 1.91 95% CI 1.12 - 3.24 p = 0.016), home birth (QR 3.26 95% CI 1.25 - 8.46 p = 0.015). Conclusion: neonatal mortality is a health problem in the InSE neonatology department. To reduce the mortality rate in this referral facility, it is essential to equip it and provide ongoing training for staff.

This paper presents a study on COb>2b> atmospheric transformation which was reacted directly with lithium hydroxide solution and metallic lithium. This solution was obtained through the reaction between metallic lithium and deionized water where hydrogen is produced and by exposing the metal at ambient conditions. In the transformation process, atmospheric COb>2b> gas reacts directly with LiOH solution, in both cases, the COb>2b> transformation kinetics was different. For this purpose, reactions between COb>2b> and LiOH solution were carried out under controlled temperature and the second process only with metallic lithium, which was exposed at room temperature, however, in these two processes lithium carbonate oxide was formed and identified. According to the results, the efficiency in COb>2b> transformation is a function of temperature value which was variable until completely obtaining the by-product, its XRD characterization indicated the formation only of Lib>2b>COb>3b> in both procedures. Under laboratory conditions lithium compounds selectively reacted with COb>2b>. In the same way, there is an alternative procedure to obtain LiOH and Lib>2b>COb>3b> for different applications in various areas.
