Nursing Portfolio EssayINTRODUCTIONRecently, ascribable to contraception fills, adolescent pregnancy has been decreased, nonetheless, issues of adolescent pregnancy have increased worldwidely, because they are not unveil superficially. First of all, adolescent pregnancy is an area where intensive nursing care and social and family support are required. In part 1, with regard to teenageds pregnancy and care, I have collected various artefacts and reviewed them. In this portfolio, I testament show how those artifacts help me to learn nursing care with regard to adolescent pregnancy including teenagers, newborn baby and family. In addition, I will present how I would utilize the artefacts to lead to my future nursing practice successfully.EFFECTS OF ADOLESCENT gestation period FOR AISHA AND JARADThe Victoria political analogy report has helped me to understand the circumstances of teenagers who have experienced pregnancy and the effects relating to their pregnancy. As a fut ure nurse, it is vital to hit the hay the social and environmental earth of adolescent pregnancy. In terms of circumstances of pregnant adolescents, it has been found that pregnancy rates are higher among teenagers who include those factors as follows (The Victoria government 2014). family violence, or sexual abuse or conflict often occurs. A teenager who has low self-esteem, low socioeconomic background. An adolescent who has low maternal instruction. rural or remote or Aboriginal or Torres Strait Islander residents.As the webpage gives the information more or less complications with teenage pregnancy, I have cognize that teenagers have greater risks of medical complications during pregnancy and the reasons. The major reasons for their medical complications are that they find out their pregnancy late or do notknow how to approach healthcare service (The Victoria government 2014). Moreover, their nutrition state during pregnancy is improper and hence, they experience premature labour and deteriorating their health condition such(prenominal) as anaemia and emotional distress.Also, the charts from sccanny organization show children born to teenage pay off have low birth weight, under 2.5 Kg (Scanny organization 2014). The information has taught me to be prepared the background knowledge of negative effects of teens pregnancy on both their children and themselves before look after an adolescent mother.PRENATAL, POSTNATAL ISSUES FOR printing AND ANXIETY IN ADOLESCENT MOTHER AND THEIR FAMILIESAs soon as an adolescent has a baby, it can be a burden to her and her family rather than merriment in normal pregnancy. Before making a nursing plan for an adolescent mother, it is essential to diagnose their depression and anxiety. The YouTube video shows what is their depression and anxiety barely and succinctly. I have comprehended that their anxiety and depression come from the problems such as parenting difficulties, continuity of study or not and finance to bre ed their children (PCA 2014). she-goat Review Organizations webpage has provided me with disgnosis and intervention with honor to teen pregnancy (Nursereview 2014). In the future practice, I will educate their family to decrease a stereotype in relation to adolescent pregnancy and emphasize the significance of education for an adolescent mother if she is concerned to the highest degree dropping her school. Besides, I will refer her to organizations to help her monetary difficulties in raising her children and also advise her to take counseling programs with regard to her study.THE SIGNIFICANCE OF FAMILY SUPPORT DURING PREGNANCY AND CHILDBIRTHThe partings of a nurse include not only caring her patient but also talking to the patients family and educate them. Above all things, in adolescent pregnancy, family support cannot be overemphasized because a teen mother is not prepared to give birth and breed. This video gives very useful tips topersuade their family that might be upset o r frustrated due to their daugthers or girl friends pregnancy in order to help the teen mother as highlighting how the teen mother feels scared and worried about her pregnancy (999advicechannel 2011). As I learned in the video, I will explain the necessity of family support and ask the family to help their adolescent mother actively in the real practice. The cooperation among the adolescent mother, family and nurse will bring about successful outcomes in the perspective of mental and physical health of the teen mother and her child.Moreover, advocatesforyouth website has offered what organization takes the initiatives and programmes for teens pregnancy in each country and the world (Graczkyk 2008). Therefore, I will recommend the programmes or organisations to a teen mother patient who does not have any family or partner that can support her in the future practice.THE NURSES ROLE IN RELATION TO CARING FOR AN ADOLESCENT MOTHER DURING PREGNANCY AND AFTERBIRTHA more anxious and depress ed teenager mother than an adult mother needs the delicate and attentive care of a nurse (Graczkyk 2008). Therefore, the role of nurse includes mothering teenagers, educating them and their family as well as conducting professional nursing practice for them (Grazkyk 2008). Essentialbaby.com websites offers Australian vaccination schedule for new born. I will memorize the immunisation schedules and also provide them to a teen mother under the hospital regulation (Baby Health 2014). In addition, I will educate adolescent mothers about the significance of immunization so that they cannot miss the proper time for immunization of their children.Also, I will provide holistic education about how to care a new born baby to a teenager mother and father as I have seen the YouTube video. I will be pleased to dispute the ways how to feed, bathe and handle a newborn baby, otherwise, I will show the education video for teenage mothers and fathers. Moreover, I will tell them if there is any urg ent situation regarding their baby, notify it to me or other nurses (InfirmaryHealth 2013).CONCLUSIONThrough this activity, I have become more confident and competent with respect to caring an adolescent mother. I have acknowledged that caring a teen mother is required a more considerate, and professional nursing headland that can consider their situation, anxiety and depression since a teen is not expected to be a mother as early as they can. I will facilitate the collaborative atmosphere among a teen mother, her family and me to create better outcomes of care in the health of the teen mother and the baby. Furthermore, I will provide explicit education for an adolescent mother and her family and guide them to appropriate programs and organization to help them. I am sure that I will be given a major role as a nurse to care a teenager mother professionally and support them so as to continue worse outcomes such as deterioration of their health and social problems.REFERENCES999Advic echannel.

Friedrich Nietzsche On Death Of God Philosophy Essay
Friedrich Nietzsche On Death Of God Philosophy EssayHistory has welcomed numerous a(prenominal) spectacular thinkers and philosophers, offering new and sometimes revolutionary ideologies which can completely modify a society. From his rejection of Judeo-Christian morality and his commentary on the Death of God, Nietzsche had become superstar of the some prominent philosophers in Europe. Often, his philosophical system isnt fully appreciated or acknowledged beca mapping of ad hominem attacks from the insanity of his later years, and the denouncement of his work because of its association with Hitler(Solomon XVIII), which is preoccupied with causation. Nietzsche is sometimes credited with being an influential figure in Hitlers life, and has gained a nonion of guilt by association. His philosophies were greatly misinterpreted and omitted by Hitler, they had opposing ideologies in anti Semitism, his views on race were contrastive and their philosophy on power and Religion.Nietz sche was born and raised in Germany and lived from 1844 or 1900 and is cited to be the first existentialist philosopher. He challenged the foundations of Christianity and presents a life affirming philosophy. The German soldiers in world war one would carry a copy of his view as Thus Spoke Zarathustra. He had influenced leading ethnical figures from different walks of life.(Solomon)Anti-Semitism was a prominent propaganda tool that had grasped the German community it was one of the guiding forces that Hitler had used to gain control(Solomon). During Nietzsches time anti-Semitism was a touristed ideology and his sister and brother in law had practiced it vigilantly(Solomon 13) . His heros, as well as most of the people around him were anti Semites so many would conclude on the basis of what his peers believed that he was an anti Semite as well. Nietzsche was also strongly against anti Semitism, although he was critical of the Judeo-Christian morality, one must not instantly relat e the two.On several accounts does Nietzsche explain his stance on Jews and Judaism, one not look further then in his book Human, all too Human. He states Every nation, either man has disagreeable, even dangerous characteristics it is cruel to demand that the Jew should be an exception(Amnation.com) implying that the Jews are not much different from other races. He goes on further to sympathize and even praise the Jews, he had stated that they had the most sorrowful history of all people(Amnation.com) and were responsible for the most effective moral code in the world (Amnation.com).Nietzsche was diagnosed as mentally ill in his later years but still continued to do by the issue, in his letters to this sister at the time he was openly hostile to her anti Semitism, he stated the name of Zarathustra is used in every Anti-Semitic Correspondence Sheet, has almost made me sick several times(consciencia.org) the book Thus spoke Zarathustra was used as a sort of literature that they titl e shared the same views. He even goes as far as to insult them he states these accursed anti-Semite deformities shall not sully my idea (consciencia.org).Hitler on several occasions demonstrates his Anti Semitism in Mien kampf Hence today I believe that I am acting in accordance with the exit of the Almighty Creator by defending myself against the Jew, I am fighting for the work of the Lord.(Nobelifs.com) Nietzsche was in direct op dress to Hitler, his writings were corrupted by the mistaking of Zarathustra and the people that Nietzsche was around, they believed since he associated with anti Semites that he was among them. The letters to his sister demonstrate otherwise and that ironically enough Nietzsche had sympathized and even praised the JewsThe most important ideology to the Nazis is arguably their belief that the Aryan race is the most superior and has the most valued purity. Hitler arrogantly pro yelled his superiority amongst all the races in the world, included the Polis h, Slavic, Arab etc. Hitlers use of the term Aryan basically is whoever he proclaimed to be, despite the linguistic and physical similarities of close nations, he consumeed many non-Aryan. Despite the similar characteristics that most poles strike to Germans, Hitler had considered the Poles as non Aryan and had stated that The destruction of Poland is our primary task.(Holocaustforgotten.com) and Heinrich Himmler had also said All Poles will disappear from the world. It is essential that the great German people should consider it as its major task to destroy all Poles.(Holocaustforgotten.com). Hitler had gone on to systematical kill 3 million polish citizens, as well as many other ethnic minorities. The irony in all this is that Nietzsche himself had stated I am a pure blooded Polish Noblemen without a single driblet of bad blood, certainly not German blood(Anti-Christ 77), it seems that Hitler had missed this very important piece of information when he read from Nietzsches books . He goes to describe the lofty position that he holds as a Polish man as a pole. You would not need to go back centurys to find instincts as pure as mine in this noblest race on earth(Anti-Christ 78) which implies a sort of arrogance that he demonstrates for his supposed Polish ancestry, which further increases the irony of Hitlers actions. There is dispute provided as to whether he is truly of full polish ancestry or not Nietzsche had no proof but it pleased him to think so(Menchen 3), but it is in any event to point because regardless he considered himself one, and insulted the German blood line. He further stresses the importance he prescribes to the polish by saying Germany is a great nation because its people have so much polish blood in their veins there were giants in Poland at the time of my fore fathers(Menchen 2) he claims that reason that Germany is so great is because of the polish It is evident that Nietzsche would have greatly disapproved of Hitlers prosecution o f Polish people.On the study of eugenics, the selection of desirable traits for humans, Nietzsche actually favored the breeding of a race more intelligent, free-thinking, and less resentful then the folks he saw around him(Solomon 14) although he didnt discuss any ideas of practicing it. The central philosophy of Nietzsches that Hitler and the Nazis had interpreted was from Genealogy of morals is the blonde Germanic beast (some claim it practiced states blonde beast) that they take as support for Aryan superiority, the Historian Kelly Ross believes that Nietzsche was racist, although in the scope it can be taken in different direction. In the same book Nietzsche all notes down what he thinks as the noble races the Roman, Arabian, German, Japanese nobility as for the Homeric heroes and the Scandinavian Vikings.(Frisian.com) He expressed praise for both Arabian and Japanese who were not Aryan stock, although what Hitler considered Aryan mainly was exclusive to mainland Germany. Hit ler and the Nazi regime had omitted several important texts from Nietzsche and mainly focused on the blonde Germanic beast and a motivational slogan. Nietzsche had claimed polish ancestry and believed the only reasons their society was successful was because of polish blood, if Nietzsche was alive during Hitler time, he would have resented him for this, not supported him.Many people dont consider Hitler not a Christian, based on his actions, not on what he believed or claimed. Whether Hitlers actions represented that of Christ or not is a separate issue, and from what historians can conclude from the evidence they have collected, Hitler was indeed a Christian. For instance, Hitler proclaimed that I am now as before a Catholic and will always remain so. And had his soldiers were had belt buckles that said Gott min uns (god with us) and had tried and true to back up his anti-Semitism with religion. Nietzsche however wasnt Christian in fact he resented religion, so much that he had cr eated the term God is Dead (Saugstad 2000). Nietzsche philosophy was based on atheism (Saugstad 2000), Nietzsche had a basic acceptance of Feuerbachs view that human beings incented God by devising of any sense of their own powers.It wasnt just it didnt believe in religion, It had resented and criticized it. In his book Anti Christ he writes Christianity is the religion of pity (Saugstad 2000) and was skeptical to the church and its ideology (Saugstad 2000). One of his main objectives was to pull the values of Plato and Christianity upside down(Saugstad 2000), Nietzsche had believed that Christianity promoted weakness and pity, and was blemish on the face of mankind, he disliked it so much that he desired for its extinction. Hitlers justification through Christianity and Nietzsches disgust for Christianity are actualisely incompatible.Hitler had manipulated Germany, to the point where his authority was basically absolute in the nation. Nietzsche had appeared to be fairly indiffer ent to semipolitical sympathies he very rarely speaks of politics (swgc.com). Nietzsche also had great distaste for authority, in the book daybreak he states in the face of any authority, one is not allowed to think, instead one has to obey(Eurozine.com), if he was in the state of Germany at this time he would have evidently hated Hitlers totalerian regime, beacuse it contradicts what he stand for.There is a photograph of Hitler staring straight off into the eyes of a Nietzches bust, and he would oftenly go to the Nietzche musem of Wiemeir to see the bust for himself. Sometimes Nietzche is victimized by the false premise that he himself, was a Nazi. This however is good refuted because Hitler did not form the Nazi party until 1919 and did not ascend to power with it until 1933, several decades after Nietzsches death. Nietzsche was also not a fascist, his ideology, was more so that, his political beliefs, if he had any at all was the belief in no politics. (Solomon 16).In other words, Hitler had take Fredrick Nietzsche and formulated his own philosophy with little to no influence by him. Their views on anti Semitism greatly contrast each other, Hitler bases much of his political career on the extermination of the Jewish race, while Nietzsche when communicate with being an anti-Semite responds with great hostility as addressed in his letters to his sister. Hitler mystifying concept of racial supremacy, drips with irony for not only did Nietzsche claim full polish ancestry, but he also insulted German blood , and the atrocities committed to the Polish in world war two would evidently not been something Nietzsche supported. Nietzsches position on religion contradicts that which Hitler uses to motivate his troops, Hitler claims to be fully Catholic and motivated by god to destroy the Jewish race, whereas Nietzsche shows mostly skepticism and pessimism. It is clear that not only did Hitler greatly misinterpret Nietzsche, the evidence points that he may have no t read much at all, and just created a piffling attachment to Nietzsche, mostly based on nothing.

Electronic Structure and Spontaneous Polarization in BiFeO3
electronic Structure and Spontaneous Polarization in BiFeO3Electronic structure and offhanded polarization in multiferroic passel BiFeO3Z. Mahhouti 1,2,3,* , H. El Moussaoui 1 , M. Hamedoun 1 , M. El Marssi 3 , A. Lahmar 2 , A. El Kenz 2 , and A. Benyoussef 1,2,4AbstractThe electronic structure, charismatic properties and spontaneous polarization in Bismuth ferrite BiFeO3 ar investigated using first-principle calculations. The computed results show that the ground state of bulk BiFeO3 is rhombohedral R3c symmetry with G-type antiferromagnetic ordering and insulating, the computed results are in good treaty with available look intos. The electronic structure has been studied using the full voltage linearized augmented plane wave (FP-LAPW) method wi comminuted generalized gradient similarity (GGA) and modified Becke-Johnson potential (mBJ). Therefore, the finding tie gap value is equal to the experimental value (Eg=2.5 eV) and much ruin than separate metaphysical values, th e local magnetic moment at the Fe atoms reaches the experimental value and it is in good agreement with previously account theoretical, with the bulky atomic displacement the modern possible action of polarization predicts a large spontaneous polarization in multiferroic bulk BiFeO3.INTRODUCTIONThe multiferroic term de zero(pre zero(prenominal)einal)es the coexistence of several ferroic orders (ferroelectric automobile, ferromagnetic, and ferroelastic) in one material1, coupled or not. Multiferroic materials are very rare because the origins of ferroelectricity and ferromagnetism are hardly compatible as shown by Hill et al.23. However, there are some exceptions such as La0.1Bi0.9MnO3 which is ferroelectric below 770 K and ferromagnetic below 105 K4. The definition of multiferroic has therefore been extended to materials with antiferroic orders such as BiFeO3 which is ferroelectric and antiferromagnetic. Bismuth ferrite BiFeO3 (BFO) is one of the few magnetoelectric multiferro ics who has simultaneously ferroelectric and antiferromagnetic orders under close conditions of temperature and pressure. Indeed, its high Curie temperature (TC = 1103 K)5 and Nel temperature (TN = 643 K)6 provide a wide range of applications at different temperatures7 such as spintronics, data storage and microelectronic devices89, In improver, a magnetoelectric coupling is possible at room temperature.Recently, BFO has seen a considerable increase in interest since the discovery of a much better spontaneous polarization, greater than 150 C/cm2, when the material is grown in thin layers10. This discovery aroused great enthusiasm among the scientific community who precious to explain the origin of some phenomenon and explore this material again.The phase diagram established accord to the reference11 shows the succession of three phases with increasing of temperature denoted , ,and , respectively. In its bulk course of instruction and at room temperature, BFO has a distorted pero vskite structure with rhombohedral symmetry and space group R3c (a = b = c = 5.63 , = 59.4)128. The primitive unit kiosk contains cardinal formula units (ten atoms), each Fe atom is surrounded by six antiparallel spin neighbors, the magnetic moments are oriented perpendicularly to the 111 direction, which leads to develop a G-type antiferromagnetic order on the whole of the material. However, new observations have revealed that the direction in which antiferromagnetism manifests rotates through the crystal13. This noncollinearity propagates within the material with a period from 620 to 640 1314 and superimposes on the G-type antiferromagnetic order. As the noncollinearity is quite minimal, the simplification to a collinear magnetic structure is possible15. In this paper, the noncollinearity effects were not taken during our calculations.Since BFO is grown as a thin layers, the material may undergo a compressive or extensive stress due to the exit between the primitive cell of t he material in its bulk form and those of the monocrystalline substrate, the small grown thickness is able to accept any relaxation of the structure. This can cause changes in the structure parameters of the crystal compared to its bulk form. However, other experimental works1617 showed that even BFO grown in thin layers, retains its rhombohedral symmetry.For a long time BFO considered too low to be exploitable ( Ps = 6.1 C/cm2 ) according to the first criterions of Teague et al.5, the ferroelectricity of BFO was studied again following the results of Young et al.10 on thin layers of BFO ( Ps = 158 C/cm2). However, many experimental studies carried out during this period gave a confound results, the spontaneous polarization varying from 2.2 C/cm2 18 to 158 C/cm2 10. The prove of the ferroelectricity of BFO is a concrete example to combine experimental results and theoretical calculations. In this case, the calculation methods take to explain the difference between the first meas ured values of bulk BFO and those admited on the same material grown in thin layers.In this paper, we study in detail the magnetic properties of bulk BFO, while considering a G-type antiferromagnetic order. But it is necessary to determine first the electronic manakin and to calculate the passel gap, in order to understand and obtain the theoretical model which corresponds to the reality of the material, and then to determine the spontaneous polarization using modern supposition of polarization. regularityThe calculations which we present in the remainder of this paper use the meanness functional theory (DFT) implemented in WIEN2k code. The interactions between electrons and ions are described in the good example of full potential linearized augmented plane wave (FP-LAPW) method. As the 3d electrons in diversity -metal Fe atom are incompletely filled, the spin density approximation was employed withinstry the Perdew-Burke-Ernzerhof (PBE) form of the generalized gradient appro ximation (GGA) and modified Becke-Johnson potential (mBJ). The new version of the exchange potential, proposed for the first time by the Becke and Johnson19, was lately published by Tran and Blaha20. The modified Becke-Johnson potential (mBJ) proposed by Tran and Blaha isWith is the electronic density, is kinetic energy density and is the potential of Becke-Roussel. In this work, the mBJ potential is used in compounding with the GGA-PBE approximation to compute the electronic structure, magnetic properties and spontaneous polarization in multiferroic bulk BFO. Our calculations do not include the spin-orbit interactions and the noncollinearity effects. The mesh of the first Brillouin zone in the reciprocal space was carried out using a 4 x 4 x 4 Monkhorst-Pack k-points grid. The structural parameters of BFO in space group R3c ( i.e, the grille constant and atomic positions ) are considered as calculated by Wang et al.8 as given from Kubel et al.12. The results of relaxing the ce ll volume, rhombohedral angle, and atomic positions within the R3c symmetry in reference8 show that there is an alternation of Bi3+ and Fe3+ ions along the 111 axis Each of these atoms is surrounded by six oxygen atoms, which thus form an octahedron around each cation. Inside the octahedron FeO6, the Fe3+ ion is distant the FeO2 plane (forming the base of the octahedron), which leads a distortion of the octahedron.The calculation of the spontaneous polarization using the modern theory of polarization is carried out by determining the difference in polarization between two symmetry (The non-centrosymmetric phase R3c which is ferroelectric and the centrosymmetric phase R-3c supposed paraelectric). In order to evaluate the polarization of the structure studied, we mustiness therefore use a structure (centrosymmetric) as a reference with the same unit cell as the real structure (non-centrosymmetric), but its atomic positions do not induce electrical dipoles. Energetically, these two s tructures are very close, which confirms our choice of R-3c symmetry as a centrosymmetric reference. They differ by the addition of a center of inversion within the symmetry, and the passage from one symmetry to the other is due to the displacement of the atoms along the 111 direction which is accompanied with a revolution of the FeO6 octahedra perpendicular to the same direction. This evolution of the paraelectric phase to the ferroelectric phase allows us to explain the birth of ferroelectricity within the bismuth ferrite BFO and to reproduce it efficiently in our calculations. The modern theory of polarization was applied for the first time to compute the ferroelectricity within the cubic perovskite-type KNbO3. The results obtained ( P = 35 C/cm2 2122) showed excellent agreement with the experimental data ( P = 37 C/cm223). Other studies were carried out subsequently, confirming the reliability of this method with respect to the experimental reality. Today, the modern theory of p olarization is widely used.Results and DiscussionElectronic and magnetic propertiesIn this section, we study the electronic structure of bulk BFO in ferroelectric R3c structure, considering the relaxing values of cell parameter, rhombohedral angle and atomic positions by Wang et al.8. We computed and plan the criminalised structure and electronic state densities with the same parameters mentioned at the paragraph II. The band gap value are calculated using mBJ potential in combination with the GGA-PBE approximation, our calculated band gap value is the same as the value measured by Gao et al.24 from the UV-visible diffuse reflectance spectrum witch is equal to 2.5 eV, our computed band gap is much better than other theoretical works such as Neaton et al.15 who found an indirect band gap of 0.4, 1.3, and 1.9 eV using LSDA+U approximation with U=0, 2, and 4 eV, respectively. The same for Ttnc et al.25 they found an indirect band gap of 0.9, 1.4, and 2.1 eV using LSDA+U approximation with U=0, 2, and 4 eV, respectively. Our band structure results (Fig.1) indicate an indirect band gap of approximately 2.5 eV witch is in excellent agreement to the experimental mensuration of about 2.5 eV 2426. Therefore, this equality between our calculated band gap and the experimental value confirms the insulating character of bulk BFO.In order to understand why the magnetic moments of the Fe atoms were arranged antiparallel within bulk BFO, we relaxed it according to different magnetic configurations paramagnetic, ferromagnetic, and antiferromagnetic. The ground-state energy of the various possible magnetic configurations shows that the G-type antiferromagnetic configuration is the one which offers the material its greatest stability. FIG. 1. Calculated band structure for rhombohedral BiFeO3.FIG. 2. Calculated total density of states for rhombohedral BiFeO3.Calculated density of state (Fig.2) for R3c BFO indicates an indistinguishable distribution between electronic states u p and down, which clearly exhibits the antiferromagnetic order of the material, in this case the antiferromagnetic order can only be G-type. The Fe atoms along the 111 axis have a local magnetic moment of 4.02 B comes from 3d states, this value is much better than 4.25 B and 4.17 B reported by Ttnc et al.25 using LSDA+U with U = 4 and 6 eV, respectively. Therefore, our computed local magnetic moment of Fe atoms is very close to the measurement value of about 3.75B 27.FIG. 3. Atomic projection of electronic PDOS for rhombohedral BiFeO3.Figure 3 shows atomic projected electronic density of states (PDOS) around the ban gap region for two spin channels. The results suggest that the valence band are predominantly formed by Fe 3d states, hybridized with a character from O 2p states. Conduction band states are occupied by a large amount of Fe 3d states, hybridized with a small contribution of Bi 6p states that also contains a significant amount of O 2p states.Spontaneous polarizationThe spontaneous polarization was calculated within bulk BFO using the ferroelectric structure R3c and the theoretical centrosymmetric phase R-3c. The centrosymmetric phase must be judiciously chosen, in order to found the difference of ferroelectric polarization between the centrosymmetric and non-centrosymmetric phases little than the quantum of polarization, Where is the electronic charge, is a lattice vector in the direction of polarization, and is the volume of the unit cell. Our calculations have shown that centrosymmetric phase R-3c is the structure closest to the ferroelectric structure R3c, both energetically as well as structural. This symmetry differs from the R3c only by the addition of a center of inversion. The transition from the paraelectric to the ferroelectric phase was characterized by a large displacement of the atoms along the 111 axis and a rotation of the FeO6 octahedra. Therefore, we expect that the spontaneous polarization develops along the 111 axis. In ord er to calculate the difference of polarization, we have considered that the transition from paraelectric to ferroelectric phase was done adiabatically and continuously. In this way, each atom moves along a path divided into segments of equal length. This method allowed us to follow the evolution of the spontaneous polarization during the whole paraelectric-ferroelectric transition. Throughout the paraelectric-ferroelectric transition, it is imperative to avoid any external contribution to symmetry, such as compression or expansion of the unit cell (in this case we do not calculate the real spontaneous polarization). For this reason, the structures used for our calculations have the same cell parameters, only the atomic positions were shifted.The modern theory of polarization compute the both, ionic and electronic contribution to the spontaneous polarization using the sum of the Wannier centers of the occupied bands. Our results showed that the spontaneous polarization developed alon g three directions, and was 58.8 C/cm2 along each axis, resulting a spontaneous polarization of 101.1 C/cm2 along the 111 axis which is in full agreement with the spontaneous polarization calculated by Neaton et al.15 using LSDA+U. Early measurements on bulk BFO single crystals5 found a small polarization of about 6.1 C/cm2. On the other hand, many experiment studies on thin film samples of BFO showed a large spontaneous polarization of about century-158 C/cm2 1610. The anomalously early value was caused by several explanations. First, the authors5 indicated that their hysteresis loops were not saturated. Second, maybe the small value limited by the poor of the sample quality. Finally, the third explanation is that the crystal structure is not the same. Recently, Lebeugle et al.28 have prepared a highly pure BFO single crystal (bulk BFO with a rhombohedral R3c symmetry) and measured the spontaneous polarization, they found a very large value of about 100 C/cm2 28 which is an intrins ic property of the bulk BFO, as expected by our theoretical studies.CONCLUSIONSIn summary, Bismuth ferrite BiFeO3 is one of a few magnetoelectric multiferroics who has simultaneously ferroelectric and ferromagnetic orders, it has seen a considerable increase in interest since the discovery of a high spontaneous polarization. The first principle calculations with our approximations and parameters chosen allowed us to understand and obtain the behaviors of electronic and magnetic properties which make possible the computing of the right band gap and local magnetic moment. The property intrinsic of the large spontaneous electric polarization in bulk BiFe2O3 showed by recently experiment studies was confirmed by our theoretical investigations using the modern theory of polarization. These good agreements between our theoretical investigation and experimental measurement allow the scientific community to compute other properties and understand the physics behind the measurement at the at omic level.References1H.

Gender Stereotypes and Toys Essay -- Gender Roles in Society
Often when a couple becomes pregnant and finds out the sex of the infant, stereotypes buzz off to form. If the child is fe phallic, their style depart often be painted pink with cutesy borders. The crib leave have pink blankets with ruffles on them. The foul up girl will be presented with soft toys and cute stuffed animals, as well as perhaps a baby doll or two. At the baby shower, the mother will typically be presented with pink and purple clothing, the colors of choice for a female child. When the baby finally comes along, she will typically be treated as a gentle princess. When it comes to girls, adults be often more careful, as if the baby girl will break. On the other hand, if the couple is having a male child, the room will be painted blue or green with borders usually depicting superheroes or sports oriented paraphernalia. Though the boy may receive stuffed animals, they are typically of a more ferocious nature than the stuffed animals a girl might receive. The blankets are usually blue or another color associated with modest boys. Perhaps one of the boys first gifts will be a tiny little catchers mitt, or something else sports related. At the baby shower, the mother will receive blue and green clothes. Family and friends are more likely to take a little boy to a sporting offspring than their female counterpart. Clearly, from the moment a child is brought into this world, they are pushed toward a certain stereotype. Now, the real question is Are boys naturally more aggressive due to high testosterone levels, or is it more culturally defined, by the way we treat our children and the gifts we bestow upon them?

Should Animals be Used for Scientific Research? Essay -- Animal Rights
Every year, millions of animals experience painful, suffering and death due to results of scientific research as the effects of drugs, medical procedures, food additives, cosmetics and other chemical products. Basically, animal experimentation has played a dominant role in leading with new findings and humane advantages. beast research has had a main function in many scientific and medical advances in the past decade and is answering in the judgment of several diseases. While most people believe than animal testing is necessary, others are worried about the excessive suffering of this innocents creatures. The offset between the rights of animals and their use in medical research is a delicate issue with huge societal assumptions. Nowadays people are trying to examine and take in consideration these social implications based in animals rights. Even though, many people tend to disregard animals that have suffered permanent damage during experimentation time. Many people try to m isunderstand the nature of life that animals just have, and are unable to consider the actual laboratory procedures and techniques that these creatures tend to be submitted. Animal experimentation must be excluded because it is an inhumane way of treat animals, it is unethical, and exist safer ways to test products without painful test.Through many years, companies have tested animals to help prove that their products are safe for humans. This has become a very inhumane practice in which many animals are subjected to intolerable rigour. Animals are treated cruelty because they are kept in cages with unhealthy conditions.
