Equilibrium and kinetic studies on the adsorption of copper onto paddy straw powder

AbstractBatch adsorption studies were conducted in the laboratory to explore the possibility of paddy straw powder as a low-cost adsorbent for the removal of copper from wastewater. The parameters affecting adsorption process such as time of contact, metal ion concentration, quantity of adsorbent and pH are also evaluated, and the results are fitted using adsorption isotherm models. It is observed from the experimental results that almost 90–95% copper can be removed from the solution using paddy straw powder. Biosorption of metal ion depends on pH, and the results indicated the optimum pH for the removal of copper as 7.0. To describe the distribution of copper between the liquid and solid phases in batch studies, Langmuir adsorption isotherm and Freundlich isotherm model have been used and it has been observed that Freundlich isotherm better represents the phenomenon. Using the Langmuir model, the maximum copper adsorption capacity was calculated to be 37.17 mg/g. The adsorption process is found to adher.
Removal of Cu ( II ) ions from synthetic waste water by using a novel biocarbon

The current research is focused on the need to find an economical adsorbent for the removal of heavy metals from industrial wastewater. The research was performed to assess the potential of a biocarbon generated from medicinal plant called Phyllanthus niruri (Phyllanthaceae) as an adsorbent in the removal of heavy metals from solution. Results from batch adsorption studies on the effect of pH, contact time, different concentration of Cu metal ions were used to estimate the optimum adsorption conditions. The obtained results showed that, the adsorption of the metal ions was dependent on adsorbent dosage, contact time and pH. The optimum adsorbent dosage, and pH, was found to be at 2.5 g and pH 4.4 respectively. The effective contact time was 150min at 30 C. The study also showed that activated carbon produced from Phyllanthus Niruri biomass can be efficiently used as low cost alternative for removal of metal ions. © 2015 Elixir All rights reserved.

J un 2 02 1 Electromagnetic waves in Born Electrodynamics

We study two counter–propagating electromagnetic waves in the vacuum within the framework of the Born–Infeld theory in quantum electrodynamics. By choosing the crossed field case E ·B = 0, i.e. G = 0, the Born–Infeld Lagrangian reduces to the Born Lagrangian, therefore for this special case we present study which is identical for the Born–Infeld and the Born electrodynamics. In this paper, we show that the non–linear field equations decouple for ordinary wave case using selfsimilar solutions and we investigate the shock wave steepening. We show that the only solutions are exceptional traveling wave solutions which propagate with constant speed and which do not turn into shocks. We discuss the phase shift and the cross section of the process. This work serves as a preliminary study towards analyzing the shock waves in the more general case in the Born–Infeld theory.

Effects of Nutritional Systems on Early Weaned Lambs

The aim of this study was monitor the effect of inducement baits and to test four nutrition systems after early weaning lambs of Blackhead Pleven sheep breed. The experiment was conducted with 80 early weaned lambs. The study shown that during partial deprivation of milk (from 14 days of age), lambs intake more feed when an inducement is placed baits. In both groups, on the last day before weaning, the lambs intake over 100 g of concentrated feed, which proved sufficient and allowed the animals to be weaned at 19 days of age. Growth of animals after weaning is higher at fed on pelleted protein concentrate and barley grain (p <0.01). This is indicative of the fact that age and body weight do not influence the growth of early weaned lambs, but the kind of forages used. Studies shown that the early weaning of lambs at an average body weight of 8.80 and an age of 19.4 days kg allowed an additional 41.8 kg of milk per sheep to reach 15 -16 kg body weight of lambs.
A three-stage heuristic combined Hopfield neural network for channel assignment problem in cellular mobile system

constraints[2]. Many researchers have investigated the CAP in telephone networks[2]-[8]. Funabiki and Takefuji [2] proposed a neural-network parallel algorithm for channel-assignment problem. All input values are sequentially updated, while all output values are fixed. Then, all output values are sequentially updated, while all input values are fixed. Their neural-network model is composed of the hysteresis McCulloch–Pitts neurons. In the Funabiki and Takefuji model, four heuristics were used to improve the convergence rate of channel assignment. Kunz [3] used the continuous Hopfield network, where the output of each neuron V i was a fixed function f of the internal state u i , i.e., V i =f(u i ) , where f(x)=1/2(1+tanh( λ x)) . The Kunz neural-network model required a large number of iterations in order to reach the final solution, and there were also difficulties in finding the proper values for λ and the parameters in the interconnection weights and energy function. Kunz considered cochannel and cosite interference in his neural-network model [3]. Chan et al. [5] used a feedforward neural network, which had a learning process prior to actual channel assignment. For the learning process, they used training data that was dependently obtained by other assignment methods. The performance of their algorithm is totally dependent on the used training data. Also, in [5], only the cochannel constraint (CCC) was considered. Vidyarthi et al. [6] proposed a hybrid channel assignment approach using an efficient evolutionary strategy. They developed an evolutionary strategy(ES) which optimized the
Visible Light Photocatalysis of BiOI and Its Photocatalytic Activity Enhancement by in Situ Ionic Liquid Modification

In this study, we investigate the photocatalysis mechanism of BiOI in detail and therefore demonstrate that the photocatalytic activity of BiOI could be enhanced greatly by in situ modification of an ionic liquid [Bmim]I (1-buty-3-methylimidazolium iodide). The ionic liquid modified BiOI (IL-BiOI) was prepared by reacting bismuth nitrate with [Bmim]I in water at 70 °C, where the ionic liquid could act as both iodine source and surface modified agent. On degradation of methyl orange (MO) under visible light irradiation (λ > 420 nm), IL-BiOI photocatalyst exhibited superior photocatalytic activity to the unmodified counterpart synthesized in the absence of [Bmim]I. The effects of ionic liquid modification on the photocatalytic activity enhancement were systematically investigated. We found that IL modification could trap the photoexcited electron at conduction band of BiOI to inhibit the recombination of photoinduced electron–hole pairs and thus enhance its photocatalytic activity on the degradation of orga.
Effect of thermophoresis , thermal radiation and heat generation on the Casson fluid flow over an exponentially stretching surface

Thermophoresis and radiative heat transfer on the unsteady boundary layer flow of a Casson fluid past an exponentially porous stretching sheet under the influence of a magnetic field in the presence of heat source/sink and chemical reaction is analysed. The governing partial differential equations of the flow are transformed into nonlinear ordinary differential equations using similarity variables which are then solved numerically employing shooting technique along with Runge-Kutta iterative scheme. The graphical results reveal that the suction and magnetic field decelerate the velocity while the Casson parameter shows an opposite trend. The thermal boundary layer thickness is increased by the Casson parameter and heat source parameter. The rate of heat transfer is enhanced by thermal radiation parameter. The thermophoresis parameter along with Schmidt number is found to reduce the concentration predominantly. © 2016 Elixir All rights reserved.

The Cross-level Relationship Between Organizational Trust in Leadership and Job Satisfaction

Previous research has rarely addressed trust in leadership at the organizational level. This study addresses this research gap by examining the influence of the magnitude of organizational trust in leadership and consensus about this trust on job satisfaction. The magnitude refers to shared trust in leadership among organizational members, whereas consensus captures the variability in perceptions within organizations, even when overall agreement exists. Moreover, the study examines the mediating role of perceived communication quality in the relationship between the magnitude of organizational trust in leadership and job satisfaction. The sample was composed of 486 employees of 34 transport organizations. Results showed that the magnitude of organizational trust in leadership influenced employees’ job satisfaction through perceived communication quality, but its direct effect on job satisfaction was non-significant. Moreover, the organizational consensus on trust in leadership was also positively associated with job satisfaction. Overall, the findings contribute to better understanding trust in leadership as an organizational phenomenon.
Collaboration and Performance in Virtual Teams with Faultlines : An Emotional Management Intervention

Problem: Virtual teams with faultlines face challenges due to their dispersion, diversity, and virtuality, which can diminish their performance. To resolve this issue, team emotional management (TEM) interventions foster teams’ collaboration capability, that is, the team’s ability to build and manage relationships based on trust, commitment, and communication. Goals: This research aimed to analyse whether a TEM intervention can enhance team performance by improving the collaboration capability in virtual teams with faultlines. Method: Fifty-two four-member teams participated in an experiment with repeated measures (three measurement times). Teams were randomly assigned to either a TEM intervention or a control condition. Main results: The TEM intervention had a positive effect on trust and commitment, but not on communication. Moreover, trust and commitment fully mediated the effect of the TEM intervention on performance. Main implications: Our findings showed the relevance of a TEM intervention in improving the collaboration capability and performance in virtual teams with faultlines. This study contributes to research on faultlines, affect management in virtual teams, and computer-mediated communication.
Identified, but not identical: exploring the influence of collective narcissism in team identification

ABSTRACT To date, inquiry into team identification has focussed on the implications for consumer behaviour, with relatively limited focus on within group differences of highly identified fans. In the current study, collective narcissism is used to explore attitudinal and behavioural differences among highly identified fans. By interviewing highly identified fans both high and low in collective narcissism, we explore the unique attributes of highly narcissistic fans and how these differ from low narcissistic fans who are equally identified with a team. We find high collective narcissistic fans possess pervasive views that the team is unique, under scrutiny, and harbour beliefs related to within-group exclusivity, whereas low narcissistic fans do not. The findings highlight the need to understand attitudinal and behavioural differences among highly identified fans. Practically, it highlights the importance of increased specificity in market segmentation of team fan bases. HIGHLIGHTS Assessing collective narcissism reveals differences among highly identified fans. Perceptions of the team (ingroup) vary by collective narcissism level. High collective narcissists emphasise ingroup uniqueness, scrutiny, and exclusivity. Comparatively, low collective narcissists have more tempered views of the ingroup.
Divergent regional evolutionary histories of a devastating global amphibian pathogen

Emerging infectious diseases are a pressing threat to global biological diversity. Increased incidence and severity of novel pathogens underscores the need for methodological advances to understand pathogen emergence and spread. Here, we use genetic epidemiology to test, and challenge, key hypotheses about a devastating zoonotic disease impacting amphibians globally. Using an amplicon-based sequencing method and non-invasive samples we retrospectively explore the history of the fungal pathogen Batrachochytrium dendrobatidis (Bd) in two emblematic amphibian systems: the Sierra Nevada of California and Central Panama. The hypothesis in both regions is the hypervirulent Global Panzootic Lineage of Bd (BdGPL) was recently introduced and spread rapidly in a wave-like pattern. Our data challenge this hypothesis by demonstrating similar epizootic signatures can have radically different underlying evolutionary histories. In Central Panama, our genetic data confirm a recent and rapid pathogen spread. However, BdGPL in the Sierra Nevada has remarkable spatial structuring, high genetic diversity and a relatively older history inferred from time-dated phylogenies. Thus, this deadly pathogen lineage may have a longer history in some regions than assumed, providing insights into its origin and spread. Overall, our results highlight the importance of integrating observed wildlife die-offs with genetic data to more accurately reconstruct pathogen outbreaks.
Ecosystem function after the K/Pg extinction: decoupling of marine carbon pump and diversity

The ocean biological pump is the mechanism by which carbon and nutrients are transported to depth. As such, the biological pump is critical in the partitioning of carbon dioxide between the ocean and atmosphere, and the rate at which that carbon can be sequestered through burial in marine sediments. How the structure and function of planktic ecosystems in the ocean govern the strength and efficiency of the biological pump and its resilience to disruption are poorly understood. The aftermath of the impact at the Cretaceous/Palaeogene (K/Pg) boundary provides an ideal opportunity to address these questions as both the biological pump and marine plankton size and diversity were fundamentally disrupted. The excellent fossil record of planktic foraminifera as indicators of pelagic-biotic recovery combined with carbon isotope records tracing biological pump behaviour, show that the recovery of ecological traits (diversity, size and photosymbiosis) occurred much later (approx. 4.3 Ma) than biological pump recovery (approx. 1.8 Ma). We interpret this decoupling of diversity and the biological pump as an indication that ecosystem function had sufficiently recovered to drive an effective biological pump, at least regionally in the South Atlantic.
A highly conserved ontogenetic limb allometry and its evolutionary significance in the adaptive radiation of Anolis lizards

Diversifications often proceed along highly conserved, evolutionary trajectories. These patterns of covariation arise in ontogeny, which raises the possibility that adaptive morphologies are biased towards trait covariations that resemble growth trajectories. Here, we test this prediction in the diverse clade of Anolis lizards by investigating the covariation of embryonic growth of 13 fore- and hindlimb bones in 15 species, and compare these to the evolutionary covariation of these limb bones across 267 Anolis species. Our results demonstrate that species differences in relative limb length are established already at hatching, and are resulting from both differential growth and differential sizes of cartilaginous anlagen. Multivariate analysis revealed that Antillean Anolis share a common ontogenetic allometry that is characterized by positive allometric growth of the long bones relative to metapodial and phalangeal bones. This major axis of ontogenetic allometry in limb bones deviated from the major axis of evolutionary allometry of the Antillean Anolis and the two clades of mainland Anolis lizards. These results demonstrate that the remarkable diversification of locomotor specialists in Anolis lizards are accessible through changes that are largely independent from ontogenetic growth trajectories, and therefore likely to be the result of modifications that manifest at the earliest stages of limb development.
Vertically migrating Isoxys and the early Cambrian biological pump

The biological pump is crucial for transporting nutrients fixed by surface-dwelling primary producers to demersal animal communities. Indeed, the establishment of an efficient biological pump was likely a key factor enabling the diversification of animals over 500 Myr ago during the Cambrian explosion. The modern biological pump operates through two main vectors: the passive sinking of aggregates of organic matter, and the active vertical migration of animals. The coevolution of eukaryotes and sinking aggregates is well understood for the Proterozoic and Cambrian; however, little attention has been paid to the establishment of the vertical migration of animals. Here we investigate the morphological variation and hydrodynamic performance of the Cambrian euarthropod Isoxys. We combine elliptical Fourier analysis of carapace shape with computational fluid dynamics simulations to demonstrate that Isoxys species likely occupied a variety of niches in Cambrian oceans, including vertical migrants, providing the first quantitative evidence that some Cambrian animals were adapted for vertical movement in the water column. Vertical migration was one of several early Cambrian metazoan innovations that led to the biological pump taking on a modern-style architecture over 500 Myr ago.
