Cadmium Removal from Wastewater using Carbonaceous Adsorbents Prepared from Sunflower Waste

This study reports the removal of cadmium from wastewater in batch mode, using two carbonaceous adsorbents viz. Sunflower Head Carbon (SHC) and Sunflower Stem Carbon (SSC) prepared from waste biomass of sunflower. The adsorbents were characterized by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray Analysis (EDX). The results of batch experiment showed that the cadmium removal was dependent on pH, Cd(II) ion concentration, adsorbent dose, contact time and temperature. The highest cadmium adsorption was found at pH = 6.0, initial Cd(II) concentration = 100 mg L-1 adsorbent dose = 20 g L-1, contact time = 120 min at temperature = 25±1°C and at 180 rpm. Langmuir and Freundlich isotherm models were applied and Freundlich model was found to fit the data well. The Freundlich adsorption capacity was 1.22 and 1.48 mg g-1by SHC and SSC. The kinetic data was well described by pseudo-second-order model with coefficient of correlation 0.9978 for SHC and 0.9981 for SSC . The adsorption process was found to be endothermic in nature. The adsorbents were desorbed using different strengths of HCl ranging from 12.5 mM to 200 mM. The highest desorption efficiency i.e. 55.6 and 52.6% from SHC and SSC was found at 125 mM.
Decomposition of crop residues and availability of nutrients to bean plants as influenced by silicate and lime.

The aim of this study was to evaluate the effect of calcium silicate and limestone on the decomposition of crop residues and the availability of bean plant nutrients. The treatments consisted of three species of covering plants: Pennisetum americanum , Brachiaria brizantha and Cajanus cajan L . and five doses of silicate (0, 25, 50, 75 and 100%) as the acidity corrective. Silicate did not interfere in the decomposition of covering plant residues, but it reduced magnesium content available in the soil and induced smaller Mg absorption by covering plants and availability after decomposition. The growth of bean plants was improved by silicate; the treatments with 25 to 75% silicate doses and brachiaria crop residues were the most efficient ones.
Designing Instruction to Improve Lifelong Inquiry Learning

Citizens need the capability to conduct their own inquiry projects so that they can make sense of claims about new energy policies, health remedies, or financial opportunities. To develop the lifelong capability to grapple with these dilemmas, we report on ways to design precollege units that engage students in realistic, personally relevant investigations. Our investigations and syntheses of related work have resulted in the knowledge integration framework. This constructivist framework shows that, to succeed, learners build on what they know and use reasoning strategies to make sense of new information. To help designers we have identified a pattern that can guide instructional designers. The pattern involves supporting students to articulate their existing ideas, add new, normative ideas, distinguish them from their existing ideas, and reflect on their experiences as they increase the coherence of their ideas. To guide students, we are currently investigating automated guidance based on analysis of natural language essays students write while investigating complex problems such as global climate change.
Turfgrass Seedling Height and Quality in Paclobutrazol- Treated Seeds of Lolium perenne L. Barrage and Festuca arundinacea L. Master

Paclobutrazol affects height and quality of seedlings of turfgrass specious. To determine the effect of paclobutrazol on seedling height and visual quality, seeds of Lolium perenne L. Barrage and Festuca arundinacea L. Master were soaked with 0, 20, 30 and 40 mgL paclobutrazol for 24 h on shaker during imbibitions stage of seed germination. Treated seeds were sowed in the soil mixtures containing 70 percent gardening soil (with clay loam texture) and 30 percent sand (V/V). Pots had 41 cm height and 23 cm wide. Lower height at three stages of measured vegetative growth was resulted in Festuca arundinacea L. Master. Paclobutrazol resulted in lower height in three stage of vegetative growth. The interaction between cultivar and paclobutrazol concentrations was significant at 30 days after planting (DAP). Treatment of Festuca arundinacea L. Master with paclobutrazol 30 and 40 mgL showed lower height at stage tree (30 DAP) while there were no significant difference in Lolium perenne L. Barrage. All of paclobutrazol treatment resulted lower wide of blade in Lolium perenne L. Barrage. Festuca arundinacea L. Master treated with 40 mgL paclobutrazol had higher visual quality. It can be concluded that different cultivar could show different response to paclobutrazol treated on seed before planting. Festuca arundinacea L. Master treated with 40 mgL may be more suitable to be used in this regard.

Application of PIC microcontroller for controlling piezoelectric Braille cell

Piezoelectric Braille cells are used in many Braille display applications. The Braille displays using piezoelectric are able to refresh the Braille character that are read by visually impaired or blind people by touching the dots at Braille cell. Each piezoelectric Braille cell consists of six or eight movable pins or dots in rectangular array. The height of pins or dots in Braille cell is controlled by a piezoelectric bimorph. This will cause the pins or dots at piezoelectric Braille cell is rise or fall and therefore, create the Braille character or word. In this paper, the piezoelectric Braille cell is integrated by using PIC18F452 microcontroller while the software is written with CCS C program language. The pin or dots at Braille cell which represent a certain character is also presented.
Exchange Rate Volatility and Investment: A Panel Data Cointegration Approach

This paper examines the link between real exchange rate volatility and domestic investment by using panel data cointegration techniques. We study the empirical connection between real effective exchange rate volatility and investment for 51 developing countries (23 low-income and 28 middle-income countries). The theoretical relationship between investment and real exchange rate volatility predicts that the effects of exchange rate uncertainty on profits are ambiguous. The empirical results illustrate that real effective exchange rate volatility has a strong negative impact on investment. This outcome is robust in low income and middle income countries, and by using an alternative measurement of exchange rate volatility.
Monitoring SO2 emission at the Soufriere Hills Volcano: Implications for changes in eruptive conditions

Correlation spectrometer measurements of sulfur dioxide (SO2) emission rates during the current eruption of the Soufriere Hills volcano, Montserrat, have contributed towards identifying different phases of volcanic activity. SO2 emission rate has increased from <200 tonnes per day (td−1; <2.3 kgs−1) in the early stages of dome growth to >550 td−1 (>6.4 kgs−1) after July 1996, with the uncertainty associated with any individual measurement ca. 30%. Significantly enhanced SO2 emission rates have been identified in association with early phreatic eruptions (800 td−1 (9.3 kgs−1)) and episodes of vigorous dome collapse and pyroclastic flow generation (900 to 1500 td−1 (10.4 to 17.4 kgs−1)). SO2 emission rate has proved a useful proxy measurement for magma production rate. Observed SO2 emission rates are significantly higher than those inferred from analyses of glass inclusions in phenocrysts, implying the existence of a S‐rich magmatic vapour phase.
Antimicrobial Activity of Thinned Strawberry Fruits at Different Maturation Stages

Among the phenolic compounds that is generally present in strawberry fruits, five simple phenolics, three flavonoids, and a stilbene were tested for their antimicrobial activity against seven fungi and one oomycete. trans-Cinnamic acid showed strong antimicrobial activity, and the antimicrobial effect of the simple phenolics decreased with an increase in the number of hydroxyl groups. Phytophthora capsici was the most susceptible to the phenolic compounds tested in this study. trans-Cinnamic acid, p-hydroxybenzoic acid, and kaempferol were mainly detected in 'Seolhyang' strawberry fruits, and the total phenolic contents of the fruits decreased during their development. Extracts of the green (1-10% red color) and red (above 90% red color) strawberry fruits reduced the mycelial growth and zoospore germination rate of P. capsici, and the extract of red strawberry fruit showed strong antimicrobial activity against the zoospore germination of P. capsici. These results indicate that strawberry fruits contain antimicrobial phenolic compounds and that strawberry fruit extract can be used as a natural fungistat.

In the end, they introduce and discuss some ongoing research efforts extending this work.
Evaluation of N2O emissions by DNDC model for sandy loam soils of danubian lowland

Abstract Except for food production the sector of agriculture contribute significantly to emissions of some Greenhouse gases (GHGs), especially N2O. Agricultural practices (especially increase of N consumption in the sector) are now recognized as a major factor influencing increase of N2O emissions into the atmosphere. Estimates of greenhouse gas emissions from the agricultural sector both at a local and regional level are necessary to create possible mitigation strategies with respect to environmental efficiency and economic possibility. We used the DNDC (DeNitrification and DeComposition) model that simulates a full carbon (C) and nitrogen (N) balance, including different C and N pools, and the emissions of all relevant trace gases from soils as NH3, N2O, NO, NO2 and N2. However, for this study only N2O was considered. Intergovernmental Panel on Climate Change (IPCC, 1997) includes methodologies for calculating both direct and indirect emissions of N2O related to agricultural production. Finally, the mo.
Comprehensive Income and Stock Return: Evidence from the Tokyo Stock Exchange

This paper examines whether the International Financial Reporting Standards (IFRS)’ comprehensive income is related with the future performance of the firms listed on the Tokyo Stock Exchange (TSE) First Section. We find that in Japan, comprehensive income is not superior to other earnings or cash flow variables in predicting future equity returns of the TSE First Section firms. Instead, the ordinary profit to total asset ratio and the earnings before interest and tax to total asset ratio demonstrate the stronger predictive power for the future firm performance.
Give Trust a Chance: A Model of Trust in the Context of an IMF-Supported Program

This paper is an attempt to identify the determinants of trust between country authorities and IMF staff in the context of an IMF-supported program. Using an outcomes-based definition of trust, a game-theoretic model is developed to compute the level of trust between the two parties. The results and the analysis of trust-related issues emerging in a program context suggest that trust between country authorities and IMF staff exerts a positive impact on the likelihood of program success through its ability to improve the quality of the design, the efficiency of negotiation, and the effectiveness of implementation of an IMF-supported program. Some initiatives to secure such benefits and enhance trust in staff are proposed.
Importance of Shear Deformation Theory in Nuclear Containment Design

Recently, several studies in limited scope have been conducted to establish the importance of the shell theory considering shear deformation in the design of nuclear containments subjected to static loads [1]. However, very few studies with dynamic loads have been undertaken. The purpose of this research is to conduct a systematic study to understand the importance of shell theory in the design of containments subjected to both static and dynamic loads. Initially, to accomplish this objective, a cylinder, with a shape similar to that of a nuclear containment, is studied for its modeling simplicity. With the information learned from this experiment, a containment that is typical to the nuclear industry is selected as the benchmark model. This model is subjected to two types of loadings, a) static load corresponding to an internal pressure generated due to the loss of coolant accident event and, b) dynamic load corresponding to an earthquake that a nuclear containment may encounter during its life cycle. At the conclusion of these experiments, based on the results obtained, the authors will make prudent recommendations.
Managing the tension between performance measurement and strategy: coping strategies

Purpose – The aim of this paper is to explore an important but relatively uncharted territory: the actual functioning of performance measurement systems (PMS) in their organisational context. The objective of the paper is to document the ways in which managers go about aligning operational measures with their organisation's strategy in practice.Design/methodology/approach – This research adopts an interpretive multiple‐case approach in order to gather rich data on the strategies used in managing operational PMS. Data were collected from detailed interviews with managers and supervisors in four government agencies.Findings – The expectations were that the operations managers would adjust their performance measures to support the changes in strategy. This was not the case. All the interviewees employed one or more tactics to cope with the tensions between strategy and performance measures. The ten tactics identified are collected into three strategies; do‐nothing strategy, pseudo‐realigning strategy, and di.
Memories in public speaking performance anxiety reconstructed: a qualitative exploration using a cognitive and etiological model

Prior research on social anxiety disorder (SAD) demonstrated the importance of anxiety provoking images, which can be related to memories. The present study examines how imagery plays a role in young adults’ public speaking anxiety. The experiential intervention imagery rescripting (ImRs), conducted in fourteen participants with public speaking anxiety, resulted in reconstructing memories from adolescence. In order to explore which themes contribute to anxiety provoking images, the study of reconstructed memories focused on the cognitive anxiety process and etiological factors. Qualitative theory-driven analysis of these memories demonstrates that the anxiety process fits the cognitive model on SAD. With regard to etiology, expected influences of negative peer behaviour and parents were small or not found whereas influence of negative teacher behaviour was found. The present results therefore suggest that ImRs could be effective for the specific anxiety group which should be directed on negative teacher behaviour as contributor to their anxiety.
Influence of integrated nutrient management on soil properties of vertisol under sorghum (Sorghum bicolor)-wheat (Triticum aestivum) cropping sequence.

A field experiment on integrated nutrient management in sorghum – wheat cropping sequence comprising ten treatments was laid out in randomized block design at Main Centre for Cropping System Research Project, Mahatma Phule Krishi Vidyapeeth, Rahuri during 1999-2000 and 2000-2001 consecutively for two years to develop appropriate integrated nutrient management system under irrigated condition. Incorporation of FYM, wheat straw and glyricidia leaves for 25 or 50 per cent N substitution in conjunction with balanced dose of NPK fertilizers increased infiltration rate, water stable aggregates and organic matter, the values of which ranged from 0.88 to 0.92 cm h -1 , 0.82 to 0.96 mm and 1.10 to 1.27 per cent, respectively; whereas bulk density decreased from 1.32 to 1.22 Mg m -3 . The soil reaction and electrical conductivity remained unaffected while the organic carbon content increased appreciably and ranged from 0.68 to 0.74 per cent. The available N, P2O5 and K2O status improved after harvest of both the crops due to integrated nutrient management by the application of 50 per cent recommended dose of fertilisers and 50 per cent N equivalent with FYM to sorghum in kharif and recommended dose of fertilisers to wheat in rabi than the continuous application of recommended dose of fertilisers to both the crops.
An Analysis of DoS Attack Strategies Against the LTE RAN

Long Term Evolution (LTE) is the latest 3GPP mobile network standard, offering an all-IP network with higher efficiency and up to ten times the data ratesofitspredecessors.Duetoanincreaseincybercrimeandtheproliferation of mobile computing, attacks stemming from mobile devices are becoming more frequent and complex. Mobile malware can create smart-phone botnets in which a large number of mobile devices conspire to perform malicious activities on the cellular network. It has been shown that such botnets can cause a denial of service (DoS) by exhausting user traffic capacity over the air interface. Through simulation and with studies in a real-world deployment, thispaperexaminestheimpactofabotnetofdevicesseekingtoattacktheLTE network using different types of strategies.We quantify the adverse effects on legitimateusersasthesizeofthebotnetscalesupinbothsparselyanddenselypopulated cells for varying traffic Quality of Service (QoS) requirements. Our results show that a single attacker can drastically reduce the QoS of legitimate devices in the same cell. Furthermore, we prove that the impact of the attack can be optimized by tuning the attack strategy, leveraging the LTE uplink MAC scheduler.
Surface viscosity and Marangoni stresses at surfactant laden interfaces

We calculate here the force on a probe at a viscous, compressible interface, laden with soluble surfactant that equilibrates on a finite time scale. The motion of the probe through the interface drives variations in the surfactant concentration at the interface that in turn leads to a Marangoni flow that contributes to the force on the probe. We demonstrate that the Marangoni force on the probe depends non-trivially on the surface shear and dilatational viscosities of the interface indicating the difficulty in extracting these material properties from force measurements at compressible interfaces.
3D inversion modelling, integration, and visualization of airborne gravity, magnetic, and electromagnetic data: The Quest Project

Airborne and ground gravity and magnetic data, and airborne time domain data have been inverted to recover 3D distributions of density, magnetic susceptibility and electrical conductivity over an area 390km x 460 km in central British Columbia. Large scale gravity and magnetic inversions were first carried out to estimate the regional models. Data for 10 subvolumes were corrected for the regional background, inverted, and merged into a final detailed model containing 32 million cells. The airborne EM data were down-sampled along the acquisition line, inverted with a 1D algorithm using a laterally parameterized method and the results stitched together to generate a 3D model. A conductance rule was used to estimate the depth of penetration and a late-time background conductivity map has also been produced for the survey area. The resulting models provide guidance to the regional structure and prospective geology and location of alteration and mineralization. The final density contrast, magnetic susceptibility, and conductivity models have been integrated into a Common Earth Model ready for 3D GIS analysis, interpretation, and integration with geologic, drill-hole, and other geophysical information. The resulting physical property models can be used to guide regional targeting and help design more detailed, follow-up data acquisition.
Turbulent geodynamo simulations: a leap towards Earth's core

We present an attempt to reach realistic turbulent regime in direct numerical simulations of the geodynamo. We rely on a sequence of three convection-driven simulations in a rapidly rotating spherical shell. The most extreme case reaches towards the Earth's core regime by lowering viscosity (magnetic Prandtl number Pm=0.1) while maintaining vigorous convection (magnetic Reynolds number Rm>500) and rapid rotation (Ekman number E=1e-7), at the limit of what is feasible on today's supercomputers. A detailed and comprehensive analysis highlights several key features matching geomagnetic observations or dynamo theory predictions – all present together in the same simulation – but it also unveils interesting insights relevant for Earth's core dynamics. In this strong-field, dipole-dominated dynamo simulation, the magnetic energy is one order of magnitude larger than the kinetic energy. The spatial distribution of magnetic intensity is highly heterogeneous, and a stark dynamical contrast exists between the interior and the exterior of the tangent cylinder (the cylinder parallel to the axis of rotation that circumscribes the inner core). In the interior, the magnetic field is strongest, and is associated with a vigorous twisted polar vortex, whose dynamics may occasionally lead to the formation of a reverse polar flux patch at the surface of the shell. Furthermore, the strong magnetic field also allows accumulation of light material within the tangent cylinder, leading to stable stratification there. Torsional Alfven waves are frequently triggered in the vicinity of the tangent cylinder and propagate towards the equator. Outside the tangent cylinder, the magnetic field inhibits the growth of zonal winds and the kinetic energy is mostly non-zonal. Spatio-temporal analysis indicates that the low-frequency, non-zonal flow is quite geostrophic (columnar) and predominantly large-scale: an m=1 eddy spontaneously emerges in our most extreme simulations, without any heterogeneous boundary forcing. Our spatio-temporal analysis further reveals that (i) the low-frequency, large-scale flow is governed by a balance between Coriolis and buoyancy forces – magnetic field and flow tend to align, minimizing the Lorentz force; (ii) the high-frequency flow obeys a balance between magnetic and Coriolis forces; (iii) the convective plumes mostly live at an intermediate scale, whose dynamics is driven by a 3-term 1 MAC balance – involving Coriolis, Lorentz and buoyancy forces. However, small-scale (E^{1/3}) quasi-geostrophic convection is still observed in the regions of low magnetic intensity.
