...(ED) is a membrane technique, during which ions are transported through a semipermeable membrane, under the influence of an electric potential. It is a very versatile technology for the separation of difficult mixtures. ED is very useful for water treatment, aiding in the removal of mineral salts, sulfate, nitrate, etc. from brackish water and seawater. ED is also useful for wastewater reduction or recovery. Some other applications of electrodialysis include: * Water reuse * Pre-demineralization * Food processing * Glycerin purification Corrosionpedia explains Electrodialysis (ED) Electrodialysis is a type of dialysis in which undesired ions are removed from solution by means of a direct current passing between two electrodes, one on each side of the membrane. It is used to desalinate or concentrate a liquid process stream containing salts. ED is a highly efficient method for separating and concentrating salts. It is also very useful in reducing salt content of process streams with high amounts of salts. Electrodialysis uses electrical potential to drive the positive and negative ions of dissolved salts through separate semipermeable synthetic membrane filters. This process leaves fresh water between the filters. Electrodialysis differs from pressure-driven membrane processes by utilizing electrical current as the main driving force in matter separation. This limits the possible solutes targeted for recovery separation to charged particles. The charged particles must...

...Throughout history, the United States military has been heavily centered and controlled by men. American males have invariably carried the burden of defending their country at all cost without any excuse. By law they are obligated to register for the Selective Service within one month of their 18th birthday and are required to participate in a national draft if needed. The Selective Service act states “it shall be the duty of every male citizen of the United States, and every other male person residing in the United States, who is between the ages of eighteen and twenty-six, to present himself for and submit to registration” (Section 453 (a), Military Selective Service Act). On the contrary, women have never held the same obligations or responsibilities...

...Selective Listening Author Institution Selective listening is considered as a negative kind of listening; the selective means that the listener is biased to what he is hearing. The term bias here is based on emotionally difficult communications or preconceived ideas. All in all, selective listening is considered as failing communication sign because by filtering some information one cannot hope to understand. For a child, he or she uses selective listening to identify people, for instance, the child knows that his mother voice is different from his father’s. In addition using selective listening a child chooses to listen to cool sound by focusing his or her attention to a specific sound or spoken words. A noisy environment is not ideal for selective listening. A child who is developing will deteriorate his selective listening when exposed to an environment with unpredictable noises (Singleton & Shulman, 2014). The suggestion I would make to optimize the child’s ability to listen to speech for him to understand are using listening games and fun activities to promote the listening. Fun activities will help especially in dealing with selective listening where children hear what they want to hear talking to the child all the time will help improve their listening skills here a parent or guardian develops a habit of narrating chores done around the house to the child. Furthermore, when reading stories to the child, one can always stop and ask them...

...woman named K.M is having twins, one boy and one girl. The baby boy fetus was not healthy; he has possible heart defect and Down syndrome. She went to her ob-gyn named Dr. Matthew J. Kachinas to talk about aborting the baby boy fetus. In January 2006 he agreed to treat her with selective termination. K.M went to her ob-gyn and discussed the selective termination to her. Dr. Matthew J. Kachinas told K.M that he has lack of experience of this procedure. After K.M had the selective termination, she came back a week in a half later and done an ultrasound and it revealed that the wrong fetus was alive. The baby boy was still alive and not the healthy girl fetus. Several days later K.M went back to her ob-gyn and got the other fetus terminated too because that fetus is the one she wanted terminated in the first place. Dr. Matthew J. Kachinas the ob-gyn blames the ultrasound for his mistakes. Kachinas was charges and lost his license. K.M got a $250,000 liability settlement. The precise ethical issue here is individual rights. K.M lost both of her twins because of her ob-gyn Dr. Matthew J. Kachinas. He shouldn't have done that procedure if he didn't know what he was doing. K.M and her husband had other alternatives than to have the selective termination. They could have kept both twins, they also could of got another doctor that knew what he/she was doing for the selective termination. K.M and her husband lost both of the twins, not just one but both of the twins. They both...

...Female Selective Abortion While females in America are making great strides in gaining equality, females throughout various countries of Asia continue to be disregarded, abused, and in some occasion, aborted before birth. In fact, studies have shown that within the last two decades of the twentieth century, several million female fetuses have been aborted (Miller, 2001). Throughout these countries with high rates of Female-Selective Abortion, or FSA, one cultural similarity exists: they are all characterized as patriarchal. Among these Asian societies which are patriarchal in nature, males dominate practically all aspects of life, both public and private. Males there are seen to control the economy by having productive property, inheritance rights, and preferred employment. From a religious standpoint, these countries view males as a symbol of purity and power, while females are linked to negative notions such as impurity, danger, and a need to be controlled by males. Even culturally, males are more accepted because some of these countries, for instance China, have a preference of having a son as the first born. With so much value place upon males, many soon-to-be parents living in these countries are hopeful that their birth child will be a male. Many pregnant couples are doing whatever they can, and with the help of new technology, to ensure that they will not give birth to a female baby. In fact, evidence has shown a substantial increase in female-selective abortions since...

...IEEE COMMUNICATIONS LETTERS, VOL. 17, NO. 12, DECEMBER 2013 2229 Selective HARQ Transceiver Design for OFDM System Zia Muhammad, Hasan Mahmood, Awais Ahmed, and Nazar Abbas Saqib Abstract—We present a novel selective Hybrid Automatic Repeat reQuest (HARQ) based transceiver design for orthogonal frequency division multiplexing (OFDM) system. The proposed method is bandwidth efficient and has lower complexity as compared to conventional HARQ method adopted by communication standards such as long-term evolution (LTE). Our transceiver design introduces an additional retransmission layer at OFDM modulation level, which is independent of conventional HARQ methods. Instead of calculating computationally expensive soft information and applying forward error correction (FEC) on the soft information, receiver requests retransmission of information symbols corresponding to the subcarriers that have signal-tonoise ratio (SNR) below a set threshold at modulation level. We also provide criteria for selective retransmission and throughput analysis with new selective retransmission approach. We demonstrate that with limited feedback at modulation layer level, the proposed method enhances throughput of the system in all SNR regimes. The proposed selective HARQ method provides great flexibility for an application to optimize throughput based on its bit error rate (BER) requirement. Index Terms—Hybrid ARQ, partial retransmission, LDPC codes, OFDM, LTE, joint detection. I. I NTRODUCTION...

...Increased use of tuition discounting appear to have made it possible for more students from all income levels to enter higher education. Colleges and universities have several distinct goals for using tuition discounts: * to increase enrollments of low-income and other under-represented students; * to raise enrollments of students with high academic achievements or other talents; * To increase revenue from tuition and fees. However, the results show that at least one quarter of the four-year private colleges and universities used discounting strategies that resulted in large losses of tuition revenue. The institutions with the greatest increases in discount rates raised their spending on institutional grants by $3,375 per full-time equivalent (FTE) undergraduate, but their tuition and fee revenue grew by just $3,069. Thus, these institutions lost at least $306 per FTE in net tuition revenue as a result of their increases in spending on tuition discounting. Some highly selective and selective institutions lost more than $800 per FTE in tuition revenue. Due to the large...

...Global Antitrust Review 2014 163 The Assessment of Selective Distribution Systems Post-Pierre Fabre CRISTIANA DE FAVERI This article develops an analysis of selective distribution systems, which considers their main characteristics, the traditional principles governing their discipline and the recent evolution of the jurisprudence of the European Courts. In the Pierre Fabre case, the Court seems to have changed its approach to the subject, as, analysing a ‘de facto’ ban on online sales, it passed from the traditional ‘effects’ analysis of these systems to their qualification as restrictions ‘by object unless objectively justified’. The legal result is unaltered as the usual criteria of competition analysis are still adopted, but new perspectives could have been potentially opened in their interpretation. Furthermore, the article also takes into account the Court’s assertion that ‘the aim of maintaining a prestigious image is not a legitimate aim for restricting competition’, which represents another aspect of the judgment in apparent contrast with the settled case law. In both instances, it presents possible explanations consistent with the tradition. Finally, it underlines the significance of the ruling in relation to the controversial topic of internet selling. I. Introduction The topic of selective distribution systems has been explored in many authoritative academic works.1 Yet, it is still important and highly debated, not only because 1 ...

...bargaining situations where debaters utilize selective presentation to try and win their arguments. This paper will define what a distributive bargaining situation is and secondly, this written discourse will define the technique of selective presentation. Furthermore, this paper will also discuss the definition of power, and the role power plays in negotiation. To elaborate on distributive bargaining situations and the use of selective presentation, I will use two arguments from a debate between James Carville, Jr., a liberal political commentator and professor at Tulane University, and S.E. Cupp, a republican political commentator, writer, and Ivey League socialite. The arguments originally specified by the republican commentator S.E. Cupp, stated “President Obama did not received the same microscope treatment that President Bush received from the media, congress, and the Senate;” and “raising taxes will not create more jobs, cutting taxes will create more jobs because businesses are job creators.” These two arguments will be used to show how selective presentation is applied in intellectual distributive bargaining situations. Before I jump into the overall essence of this paper I would like to emphasize the race factors that come with the first argument that will be analyzed. Secondly, I will also touch on the problematic and complex intricacies that the second argument relates to concerning the gap between the wealthiest one percent of Americans and the rest of us. As...

...How selective did Irish nationalists have to be to establish continuity with the national past? PLAN Introduction: what is the national past? What was the aim and beliefs of the Irish nationalists? Discuss Hobsbawm’s, Inventing traditions What was the Gaelic league? How did this effect the continuity of the national past? What was the Easter rising? What was the Irish nationalist’s part in this, and how selective did they have to be to ensure continuity of the Irish past? What do sources suggest? How the Irish past was reinvented? How did people’s perspective of the Irish national past differ through the years? What was remembered selectively and what was easily forgotten to suit a certain set of beliefs at that time? What rules, regulations, rituals, practises were used to ensure continuity of the national past? Conclusion – What have we learned from sources regarding Irish Nationalism and the continuity? Compare evidence, and conclude. I am going to discuss how selective Irish nationalists had to be to establish continuity. Firstly the Irish Nationalists are a broad group who assert the view that the rule of the London government was the damage of Irish tradition. One very important factor is the invention of tradition, throughout this essay I will be discussing ways in which Irish nationalists used this to ensure certain parts of past history were remembered by inaccurate telling’s and how these traditions were passed down throughout generations, I will...

...before birth, it is becoming increasingly common practice for parents to undergo prenatal genetic diagnosis (PGD). Subsequent selective abortion appears to be the rational course of action following PGD that reveals a fetus that carries certain markers for a disease or disability. However, many disabilities rights advocates, such as Marsha Saxton, argue that this practice is harmful and morally problematic because of what it implies about the value of those currently living with conditions that would likely be selected against. In this paper, I will present Saxton’s Expressivity Argument, as well a few of the most persuasive counterarguments to her stance, and then explain why I am not compelled to discredit the Expressivist Argument by these objections. Saxton’s Expressivist Argument takes the following...

...CHILD ANXIETY 1 Child Anxiety Jeremy L. Hoellein September 30, 2012 Bellevue University CHILD ANXIETY 2 Child Anxiety When discussing anxiety in children, there are three main anxiety disorders that are unique to children alone. These disorders are separation anxiety, selective mutism, and reactive attachment disorder. While anxiety can be seen as a normal part of childhood and learning to adapt to new surroundings and situations, for some children, this anxiety can be persistent and intense. Furthermore, this persistent anxiety can lead to interfering with the child's ability to make new friends, trouble in school, and trouble with sleeping. Separation anxiety can occur in a child when a parent or caregiver leaves the room or even when they are dropping their child off to a daycare or preschool environment. Most of the time, separation anxiety will diminish the more the child gets acclimated to their new surroundings and environment. If separation anxiety persists, the child may also have fears of something bad happening to their parents while they are not around. Symptoms of separation anxiety include: excessive distress when separated from a caregiver, nightmares, reluctance to go to school or go to sleep without the caregiver nearby, and repeated physical complaints (Stafford...

...THE EFFECT OF SELECTIVE ATTENTION ON THE ACADEMIC DEVELOPMENT OF THE NIGERIAN STUDENT BY GODWIN EIGBE A PAPER PRESENTED AT THE INSTITUTE OF OPENCAST MINING AND TECHNOLOGY BENIN CITY 23RD AUGUST, 2013 Introduction The poor performance of Nigerian students in both internal and external examinations have been decried in many quarters across the country and many have blamed the society, the schools and parents for their role in the deteriorating level of academic performances. Not many have questioned the role of the students themselves in the dilemma that has befallen them. The search for a permanent cure to this menace has been on for decades. However with every new dawn the case seems to go worse. There are many who blame the poor economy as a result of high level corruption being perpetrated in government and political circles. Others believe that the school system is failing and is not doing enough to ensure that students get the maximum attention necessary for excellence. And there are others who believe that neglect on the part of parents is responsible for poor performances in schools. However true these factors are, no independent factor can be singled out to be more responsible for the problem of poor performance by students in schools. More recently, many researchers have identified lack of seriousness, laziness which leads to procrastination and corruption and examination malpractices in schools...

...When faced with a choice between engaging in Asia or Europe, the U.S. should maintain its security involvement in Asia. The region of Asia, namely China, may in fact pose as a threat to the U.S.’ status as a hegemonic world power. Despite the fact that the U.S. continues to hold on to its past reputation as an indisputable superpower, the U.S., as a nation struggling to maintain its image as leader of the world, would do well to ensure other “threatening” nations do not surpass them in energy security, military, or nuclear superiority. Both from a Neo-isolationist perspective as well as from a Selective Engagement perspective, the notion that these supposedly threatening nations are aiming to attain an image like the one the U.S. has of itself is not a fact but rather a domestically political concept the U.S promotes in order to justify its interventionist and at times aggressive behavior abroad. Instead, the U.S. engages in the international arena as a form of pre-emptive self-defense—a lesson learned from WWII. As such, because of the democratic peace theory and the race to acquire energy, Asia is a more important arena for the U.S to focus on. From a Neo-isolationist perspective, the U.S.’ engagement abroad makes it susceptible to entries into regional conflicts, and may cost it both financially and in lost lives. Thus, engagement in a region unlikely to breed conflict—supposedly Europe—would be the best strategy for the U.S.. However, while it is true that Europe has been...
