Retrospect and Perspective of Micro-mixing Studies in Stirred Tanks

Mixing problems are most likely encountered and sometimes can be severe in scaling-up projects. Micro-mixing is an important aspect for fast or quasi-instantaneous reactions. Poor micro-mixing might produce more undesired by-products, leading to higher purification costs. This paper gives an extensive review and analysis of micro-mixing studies in single- and multi phase stirred tanks. The relevant experiment techniques, micro-mixing models and nurherical approaches are critically reviewed and analyzed with remarks and perspectives. The reported studies on two-phase micro-mixing experiments and on the impact of the presence of the dispersed phases on turbulence have been limited to a narrow range of conditions. More importantly, disparities widely exist among different reports. Both Lagrangian and Eulerian models are based on oversimplified assumptions, which may lead to uncertainties or even unrealistic results. A heuristic model, which is from the perspective of CFD （computational fluid dynamics） and can cover the whole spectrum of scales and also focus on every subrocess, is desired in the future.

Maximum Data Collection Rate in Rechargeable Wireless Sensor Networks with Multiple Sinks

In rechargeable wireless sensor networks, a sensor cannot be always benefi cial to conserve energy when a network can harvest excessive energy from the environment due to its energy replenished continually and limited energy storage capacity. Therefore, surplus energy of a node can be utilized for strengthening packet delivery efficiency and improving data collection rate. In this work, we propose an algorithm to compute an upper data generation rate that maximizes it as an optimization problem for a network with multiple sinks, which is formulated as a linear programming problem. Subsequently, a dual problem by introducing Lagrange multipliers is constructed, and subgradient algorithms are used to solve it in a distributed manner. The resulting algorithms are guaranteed to converge to an optimal data generation rate, which are illustrated by an example in which an optimum data generation rate is computed for a network of randomly distributed nodes. Through extensive simulation and experiments, we demonstrate our algorithm is efficient to maximize data collection rate in rechargeable wireless sensor networks.

Postcolonialism and the Feminine in Paulina Chiziane＇s O alegre canto da perdiz

In this study we present the novel O alegre canto da perdiz （2008）, by Paulina Chiziane, focusing on the path of the characters Delfina and Maria das Dores, pointing to the construction of a female speech denouncing the state to which the Mozambican woman was subjected, especially during colonization, a trauma still present in Africa. By telling the saga of these two women （mother and daughter）, the novel also makes a reinterpretation of the origin and history of the peoples of Africa. Beyond the issues that mark the secular submission of women to the world of man in certain African societies, Paulina Chiziane also leads us to confront the issue of reductionism practiced by those who look from outside Africa and seeks to present its history and its literature as if the African continent were a single country, as reported by the Nigerian novelist Chimamanda Adichie in her speech against ＂the danger of listening and repeating a single story, the winners＇ story＂ （Adichie, 2009）. We aim to identify aspects of the unique feminine of Paulina Chiziane by rescuing legends of matriarchy in the course of the characters. We will also do a reading of colonialism and post-colonialism objectifying the female of writing Paulina Chiziane. The critical placement of the text allows us to analyze it with the contribution of Spivak （2010）, Said （1978）, Bonnici （2000）, among others.

Eco-Justice and the Niger Delta Environmental Challenges： Reflections on Matt. 7.12

Environmental challenges of the Niger Delta region caused by the activities of the oil and gas industry as well as the disregard of the region by both the oil firms and the state of Nigeria have been contentious in the discourse of environmental issues in Nigeria. In this dilemma, it appears that the oil communities are powerless in the face of the obnoxious display of might and the right to make and apply policies that affect the general well-being of the Niger Delta people and their environment. The question that might arise in this situation is the ethical perception of some of those who make and execute policies about the ecological problems of the region. Therefore, this paper focuses on discussing eco-justice in the light of Jesus teaching on equity and equality in Matt. 7.12, where he counsels that human actions on the others should be moderated by the actors＇ desire for his well-being.

Accelerated Matrix Recovery via Random Projection Based on Inexact Augmented Lagrange Multiplier Method

In this paper, a unified matrix recovery model was proposed for diverse corrupted matrices. Resulting from the separable structure of the proposed model, the convex optimization problem can be solved efficiently by adopting an inexact augmented Lagrange multiplier (IALM) method. Additionally, a random projection accelerated technique (IALM+RP) was adopted to improve the success rate. From the preliminary numerical comparisons, it was indicated that for the standard robust principal component analysis (PCA) problem, IALM+RP was at least two to six times faster than IALM with an insignificant reduction in accuracy; and for the outlier pursuit (OP) problem, IALM+RP was at least 6.9 times faster, even up to 8.3 times faster when the size of matrix was 2 000×2 000.

Igbo Language and Identity

This paper sought to identify the position of Igbo language in relation to its identity both in Nigeria and world wide Specifically, it expounded the problems hindering the study of Igbo language. A study of Igbo language and identity is pertinent because language and culture are attached to man＇s identity and human interaction Unfortunately, most of the Igbos do not want to be identified with this language called Igbo. The paper reviewed available literature on Igbo language and highlighted some strategies for increasing the interest of people in learning Igbo language. It was discovered from the study that pedagogical problems, tone problems, orthography and diacritic problems, are some of the issues that inhibit the repositioning of Igbo language as lgbo man＇s identity In view of this, it was recommended among others that Igbo linguist should try and document all the slight phonological and word differences existing in the dialects and absorb them in central Igbo

Frictional contact algorithm study on the numerical simulation of large deformations in deep soft rock tunnels

There exist three types of nonlinear problems in large deformation processes of deep softrock engineering, i.e., nonlin- earity caused by material, geometrical and contact boundary. In this paper, the numerical method to tackle the nonlinear eontact and large deformation problem in A Software on Large Deformation Analysis for Soft Rock Engineering at Great Depth was presented. In the software, based on Lagrange multiplier method and Coulomb friction law, kinematic constraints on contact boundaries were introduced in functional function, and the finite element equations was established for two incremental large deformation analyses models, polar decomposition model and additive decomposition model. For every incremental loading step, by searching for the contact points in the potential contact interfaces （the excavation boundaries）, the Lagrange multipliers, i.e., contact forces are cal- culated iteratively by Gauss-Seidel method, and justified through satisfy the inequalities of static constraint on contact boundaries. With the software, large deformation and frictional contact of a transport roadway were analyzed numerically by the two models. The numerical examples demonstrated the efficiency of the method used in the software.

Media Influence Over the Transformation of Stigma Toward Depression in Japan

in Japan, the number of depression patients has markedly increased over the last 10 years, and depression is now a major social concern. Moreover, there are concerns that patients with depression are not always seeking the treatment they need, in part due to the stigma associated with the illness. Despite of increasing public awareness of depression, the stigma has not lessened, but has changed in form. Previous studies report that depression which was once viewed as a special psychiatric illness is now viewed as a ＂common＂ mental illness. The author, too, believes that the nature of the stigmatization has changed in recent years to become more complex and ultimately continues to present a barrier to treatment for people with depression. This study aims to explore how the stigmatization has changed by examining one specific aspect in society that may have contributed to this change, namely, the media＇s portrayal of depression. The author presents and discusses clear examples of how the Japanese media＇s portrayals of depression have changed, particularly over the last 20 to 30 years, and discusses how media influence could have contributed to the shifts in stigmatization, with reference to labeling theory and growing social isolation.

Modified Augmented Lagrange Multiplier Methods for Large-Scale Chemical Process Optimization

Chemical process optimization can be described as large-scale nonlinear constrained minimization. The modified augmented Lagrange multiplier methods (MALMM) for large-scale nonlinear constrained minimization are studied in this paper. The Lagrange function contains the penalty terms on equality and inequality constraints and the methods can be applied to solve a series of bound constrained sub-problems instead of a series of unconstrained sub-problems. The steps of the methods are examined in full detail. Numerical experiments are made for a variety of problems, from small to very large-scale, which show the stability and effectiveness of the methods in large-scale problems.

Improvement of Lagrangian relaxation performance for open pit mines constrained long-term production scheduling problem

Constrained long-term production scheduling problem(CLTPSP) of open pit mines has been extensively studied in the past few decades due to its wide application in mining projects and the computational challenges it poses become an NP-hard problem.This problem has major practical significance because the effectiveness of the schedules obtained has strong economical impact for any mining project.Despite of the rapid theoretical and technical advances in this field,heuristics is still the only viable approach for large scale industrial applications.This work presents an approach combining genetic algorithms(GAs) and Lagrangian relaxation(LR) to optimally determine the CLTPSP of open pit mines.GAs are stochastic,parallel search algorithms based on the natural selection and the process of evolution.LR method is known for handling large-scale separable problems; however,the convergence to the optimal solution can be slow.The proposed Lagrangian relaxation and genetic algorithms(LR-GAs) combines genetic algorithms into Lagrangian relaxation method to update the Lagrangian multipliers.This approach leads to improve the performance of Lagrangian relaxation method in solving CLTPSP.Numerical results demonstrate that the LR method using GAs to improve its performance speeding up the convergence.Subsequently,highly near-optimal solution to the CLTPSP can be achieved by the LR-GAs.

Power Allocation for Energy Harvesting in Wireless Body Area Networks

Wireless Body Area Networks(WBANs) are expected to achieve high reliable communications among a large number of sensors.The outage probability can be used to measure the reliability of the WBAN.In this paper,we optimize the outage probability with the harvested energy as constraints.Firstly,the optimal transmit power of the sensor is obtained while considering a single link between an access point(AP) located on the waist and a sensor attached on the wrist over the Rayleigh fading channel.Secondly,an optimization problem is formed to minimize the outage probability.Finally,we convert the non-convex optimization problem into convex solved by the Lagrange multiplier method.Simulations show that the optimization problem is solvable.The outage probability is optimized by performing power allocation at the sensor.And our proposed algorithm achieves minimizing the outage probability when the sensor uses energy harvesting.We also demonstrate that the average outage probability is reduced with the increase of the harvested energy.

Climate Change and Human Health in Nigeria

This paper investigates the impact of climate change on human health in Nigeria. The paper relies on secondary data, sourced from journals, government documents and private individuals. From these sources the paper discovered that climate change poses a wide range of health risks to human health which include direct effects on human health resulting from increase in temperature and amplified air pollution that increase in temperature needs high incidence of vector-borne diseases such as malaria, dysentery and cholera among others. Climate change also leads to rising sea levels which contaminates coastal fresh water and makes low-lying areas vulnerable to flooding. Flooding results in frequent incidences of malaria, cholera, typhoid to mention but few. It also leads to the displacement of people and resource conflicts, e.g., land and water, and post-disaster mental health problem. Finally the paper suggests that after flooding, affected settlements should be fumigated before people pack tack in order to reduce the incidences of cholera, malaria and dysentery among others, and that to reduce the discharge of carbon into the atmosphere alternative source of energy to fuel wood, must be put in place by the government.
