Stages of Prenantal Development Essay Example

Stages of Prenantal Development Paper The intricate details of life begin with a single cell that develops into a full term fetus within approximately 38-40 weeks. The prenatal development stages outline the growth of the child and give a clearer picture of the development of the child in the womb. The course of this prenatal development is divided into three main periods:  germinal, embryonic, and fetal. The germinal/conception stage begins with conception, occurs within the first 2 weeks. This journey begins when the sperm and egg cell unite in one of the two fallopian tubes. The fertilized egg, known as a zygote, then moves toward the uterus, a journey that can take up to a week to complete. Cell division begins  and continues rapidly forming a blastocyst. Finally, the blastocyst arrives at the uterus and attached to the uterine wall, a process known as implantation. The conception stage is basically the preparatory and preliminary process of prenatal development that readies and prepares the body for the impending pregnancy. Once implantation has occur the the blastocyst is develops into an embryo. This second stage, the  embryonic period  occurs 2-8 weeks after conception. This is referred as the most important stage of prenatal devllopment as the foundational development of the embryo begins here. During this period, the rate of cell division increases, support systems for the cells form, and organs appear. The mass of cells attached to the uterine wall forms two layers and is now called the embryo. The  inner layer of cells of the embryo is the endoderm  which develops into digestive and respiratory systems.

The middle layer known as the  mesoderm will develop into the circulatory system, bones, muscle, excretory system, and reproductive system. By the 8th week teeth and intestines start the form as well. From the 11th week onwards, the child is called a fetus, and this stage is the last of the prenatal development timeline. This stage culminates in the birth of the child. Development of the fetus continues rapidly throughout most of this period. The fetus develops hair, nails, vocal cords, genitals, hardened bones, and a functioning liver and kidneys. By about the 20th week fat starts accumulating under the skin, the heart starts pumping more amounts of blood each day, and the baby also starts experiencing hiccups. The rate of development continues slowly as other body systems such as ligaments, brain and eyes continue developing. Up to the 40th week, the main task is the formation of the lungs, as most other body parts and organs are ready. The child starts developing necessary immunities, and also starts fattening up to face the outer environment. By about the 39th week, the child will be ready to be born into this world. During pregnancy there are 3 trimesters. A trimester is referred to as a three months period. Most commonly, the first trimester is defined as from conception through week 14. The second trimester is from week 14 through week 28. And the third trimester is from week 28 through labor and deliver, which varies considerably but averages at week 40.

Jack and Ralph Lord of the Flies Essays

Jack and Ralph Lord of the Flies Essays Jack and Ralph Lord of the Flies Essay Jack and Ralph Lord of the Flies Essay Essay Topic: Lord Of the Flies In the novel The Lord of the Flies, Jack and Ralph represent two separate entities that increasingly butt heads with each other as the novel progresses. These two characters have completely different viewpoints on what should be happening while they are in the situation that currently has a grasp on them. Ralph tries to lean towards a more civilized route on the way things should be and what everyone should do to get out of the situation they are in on the island that could easily mean life or death. Jack isn’t as focused on getting things organized and sorted out for a chance of rescue off the island. He leans towards a savagery and barbaric like way of things as he is presented with different situations that he could be civilized about but instead acts with an opposing force to Ralph and his way of how things should be. With these two characters being so different from one another it is hard for everyone else because they must make a choice on who to follow and take orders f rom. How do these two entities represent human nature and what defects it may really have? Ralph represents leadership, the properly socialized and civilized young man. This is the presumably good and just side of humans that most attribute to as good and well-behaved. Normally you’d see these types of people curing diseases and creating things that before were said to not be able to be created. These traits make for a good leader who will usually take up a task that someone else would never even want to be presented with. Even though these traits and qualities seem great and almost perfect, there is a side to these kinds of people that might make you second guess on your current thoughts about the â€Å"properly socialized and civilized man. This side is what I callsurvival. The survival trait among humans is hereditary to all as it is what we were forced to reside to always in the ancient times. But this trait for this type of man can be harmful as it has the

La bodas de Sangre - Blood weeding (federico Lorca) & Blood weeding Essay

La bodas de Sangre - Blood weeding (federico Lorca) & Blood weeding Film (Carlos Saura) - Essay Example In reference to Leonardo as the dark river shows honor and life-death as the connection is fairly clear when the Bride refers to the fatal force of the dark river in contrast to the â€Å"little bit of water. The â€Å"little bit of water symbolizes the Bridegroom from which she hoped for children. Symbolism that in the film, the orange blossoms that the bride wore were fake and waxy which symbolized the fake society in which she lived. In the movie the bride wears the fake orange blossoms to her wedding as it symbolizes her conformity to the society in almost a mocking way.   This goes together with the black dress she wears for the wedding, as if symbolizing her despair and sadness at having to go through with the wedding  when she really loves Leonardo. The lyrics impulse of the play culminates in the film, where the themes of honor and passion are absorbed in the theme of death that which paradoxically is life. The play of double perspective of death that are suggested in the dual manifestation as death is said to be an Old Woman demanding for a crust of bread. In another image Death is said to be white faced and the moon longing for life and seeking in the death of the men is symbolized by a heart, the crest of the fire, and red blood for his cheeks. The ceremony of p reparing the Bride in the church and the festivities preceding the entry of the Bride and Groom in to the bridal chamber. Both lyrics employ the familiar symbol of a flower, branch, and stream and both make visible another thread of symbol that is to become prominent as the themes of pride and passion move toward their ultimate resolution in the theme of death. The symbol of fire is enhanced as it is associated with honor as well passion and death. The horse in the Lullaby is to be identified with Leonardo’s horse and his wounds with the fate of Leonardo is indicated by the action accompanying the song.

Business Law in Australia Essay Example | Topics and Well Written Essays - 1000 words

Business Law in Australia - Essay Example This clearly makes the advertisement misleading and deceptive or as the addition of 1977 to the provision said "is likely to mislead or deceive'. This section provides the consumers protection against false company promises and advertisements. David Harland even believed that this law protected consumers from deceptive advertisement and promotional stuff.( Cornwall-Jones, 2000) Section 52 is perfectly applicable to the conduct of ABCD co, because it satisfies all the requirements of s 52. Firstly, the act is primarily applicable to corporations and ABCD co, is a corporation. Secondly, the conduct has occurred in the field of " trade and commerce". Thirdly, the offending party, the wine company, was " engaged in the conduct" which means as it was the one that offered the tickets and later revoke it without any prior notice to its consumers; it was engaged in the misleading conduct. Fourthly, their conduct, which is under analysis, was misleading and deceptive. ABCD co may state that they did not intend to mislead or deceive, but it is of little importance as their conduct misled consumers like Bob and Sally. The Carlill v. Carbolic Smoke ball case can be used to support their case. it is one of most famous cases in the common law of contracts. Carbolic Smoke Ball Company claimed to have made a product that could protect its users for contracting influenza a nd if someone would contract, the company would pay 100 pounds to its user. It became very popular in 1890s and was being sold throughout Britain and North America. For Mrs. Carlill the product did not work and she contracted influenza. She wrote to the company and she was told that advertisement wasn't serious. So she filed a suit against them. The Carbolic Smoke Ball Company defended its case by saying that she neither informed them that she was using the product and wants its price in case it did not work or did they benefit from her use. However, the court overruled both the arguments because it defended Mrs. Carlill by saying that she had entered an agreement with the company as soon as she bought product and the product was " unilateral offer". Thus, as a result the company had to pay her the promised money. It brought into the enforcement the law of " unilateral offers", where the consumer accepts the offer when he simply buys the product. As soon as the sale of product takes place, he comes into contract with the company and he is entitled to all offers, privileges, gifts being offered with the product. (" Carlill v. Carbolic Smoke Ball"), ("Carbolic Smoke Ball") If ABCD co may try to defend its position by showing the notice, in which the offer has been revoked and which appeared half an hour before Bob and Sally reached there or it may have already added an exclusion clause that would protect the company from any liability resulting from the breach. With the help of section 52, the power of any such exclusion clause will be reduced to great extent. (Cornwall-Jones, 2000) However, section 52, does not provide any remedies for the losses incurred by the people. Part VI of the TPA provides recoveries for a breach of s 52, and it includes s 82 damages, s 87 court orders and s 80 injunctions. It is not sufficient that a certain advertisement is proved as misleading; the consumer has to bring into light the losses he incurred as a result of being misled. Section 82 provides remedies for

Role of education in changing gender relations and empowerment of Literature review

Role of education in changing gender relations and empowerment of women - Literature review Example This essay "Role of education in changing gender relations and empowerment of women" outlines the role of the schooling and equal rights and attitude to both genders in society. Findings from Wajcman (2013: p29) show that there is a complex relationship between overall education rates of penetration in countries and differences between these rates in men and women. A report on statistical analysis of various developed and developing nations found that relationships between overall literacy divide and gender divide is tenuous and is not supportive of the argument that literacy and gender move together. This shows that there is a need for the disentanglement of social aspects of education access from others that are more related to physical access. Groups with power and privilege normally leverage this combination of social and physical access in different ways, as compared to marginalized and vulnerable groups (Wajcman, 2013: p29). Most experts argue that the ethnocentric western way in which educational empowerment is interpreted does not take into consideration the social and historical contexts within which education is used and accessed. Time for women is a vital resource whose supply is short and, therefore, any educational solution that seeks to improve women’s lives and improve their choices and empowerment should be seen as accessible and relevant means to improve efficiency, instead of as an additional load to their already numerous responsibilities (Wajcman, 2013: p29).... Gender differences in education are variously described as rooted in perceptions and attitudes concerning education. For example, time for women is a vital resource whose supply is short and, therefore, any educational solution that seeks to improve women’s lives and improve their choices and empowerment should be seen as accessible and relevant means to improve efficiency, instead of as an additional load to their already numerous responsibilities (Wajcman, 2013: p29). Beyond the leisure time for women away from productive and reproductive tasks, which is limited, women usually do not have the required mobility to go to school, which may be symptomatic of carious socio-economic factors, safety precautions, and cultural restrictions. Improved education and literacy are linked with correlated improvements in participation in global and local communities, as well as in individual empowerment. According to Kane (2005: p78), women living in developing nations are in the deepest po rtion of the education divide and are increasingly removed from this experience by their male counterparts who share their poverty. Factors that are engendered, such as language, constraints of time, income, cultural contexts, and education, affect the access by women to employment, education, and to academic institutions. The limited access to education by women comes from illiteracy barriers, time constraints, and preoccupation with their survival in oppressive and egalitarian socio-cultural practices and norms, the predominantly urban nature of the academic facilities, and its high costs (Kane, 2005: p78). Therefore, literacy and education are

History Of The Bahai Faith Religion Essay

History Of The Bahai Faith Religion Essay The Bahai Faith is an independent monotheistic religion. The Bahai Faith is an independent religion in the sense that it has its own scriptures, own laws, own holy days as well as its own calendar. This faith is known to be one of the fastest growing religion in the world and is spread to at least 250 independent nations in the world. The Bahai Faith represents approximately 2112 ethnic and tribal groups and is composed of as many as over six million people who have declared themselves as followers of the Bahai Faith. This faith is distinct in terms of the diversity of the believers of the faith. The Bahai Faith is a global religion as the believers come from different cultural, ethnic, professional and social class background. The second figure, Bahaullah (Glory of God) was known to be the founder of the Bahai Faith. Bahaullah was born as Mirza Husayn- Ali Nuri in Tehran, Persia who was the son of a prominent Iranian noblemen. He was one of Babs first disciples as well as the most renowned one. In his 20s, he renounced a life filled with wealth, privilege and high social standing in order to join the Babis and fight for humanitarian rights. When the Babis were being persecuted after the death of the Bab, Bahaullah also suffered and was thrown into the Siyah-Chal which is a black pit. It was during his imprisonment here where he received revelations through a maiden from God of him being a Messenger of God and him being the prophet of which the Bab had predicted. While most of the Babis were being killed, he was spared and released from prison but he was consequently exiled from Iran by the government. Bahaullah then made his way to Baghdad and began the quest to revive the Babi community there. Due to this , he was again exiled to Constantinople but before his departure, he revealed to his followers that he was the manifestation of God. This incident marked the birth of the Bahai Faith. After his stay in Constantinople, he was again asked to depart for Adrianople, Turkey. Here, he openly revealed his claim of being the messenger of God and began proclaiming his station openly to the world at a larger scale. It was here also when Bahaullah sent a series of letters to the leading monarchs of his time to inform them about his faith. The monarchs included Pope Pius IX and Queen Victoria. Bahaullah was subsequently sent to Akka which is the modern day Acre, Israel. His final years were spent here but before his death, he assigned and declared his son, Abdul-Baha as the Centre of the Covenant, successor and interpreter of Bahaullahs writings. The third figure, Abdul-Baha known as the Servant of God was the oldest son of Bahaullah and the successor of the leader of the Bahai community. His appointment was stated in the will of Bahaullah. Abdul-Baha was born as Abbas Effendi in Tehran. His birth was special as that day marked the start of the mission of the Bab. From a very young age, he experienced the sufferings of exile and imprisonment alongside his father. Under his leadership, the Bahai Faith expanded beyond the Middle East and found its way to Europe as well as North America.

Insulin Resistance In Diabetics Health And Social Care Essay

Correlation of Insulin Resistance in patients with type 2 Diabetes Mellitus utilizing Homeostasis Model Assessment of Insulin Resistance ( HOMA-IR ) with organic structure mass index ( BMI ) and Waist-Hip ratio ( WHR ) . Diabetess type 2 is a chronic upset characterized by variable grades of insulin opposition, impaired insulin secernment, and increased glucose production. It consequences from a combination of distinguishable familial and metabolic defects in insulin action and/or secretion.1, 2 Insulin opposition is the reduced ability of insulin to move efficaciously on mark tissues and is a outstanding characteristic of type 2 DM.3-6 It besides consequences from a combination of familial susceptibleness and fleshiness, and has a positive correlativity with organic structure bole fat, ( BMI ) , organic structure fat mass ( kilogram ) , and organic structure fat percentage.4, 6-16 Intra-abdominal fat terminals and lessening in femoral fat are besides independent lending factors for insulin resistance.14 Higher degrees of go arounding insulin will nevertheless normalise the plasma glucose, therefore insulin opposition slightly comparative. The most common type of insulin opposition is associated with corpulence and obesity.8 A fasting serum insulin degree of greater than the upper bound of normal for the check used is considered grounds of insulin opposition. However the gilded criterion for look intoing and quantifying insulin opposition is the hyperinsulinemic euglycemic clinch method. But due to the complicated nature of this technique ( and the possible dangers of hypoglycaemia in some patients ) , options have been sought to simplify the measuring of insulin opposition. The first was the Homeostasis Model Assessment ( HOMA-IR ) . Fasting insulin and glucose degrees are used in both to cipher insulin opposition, and both correlative moderately with the consequences of clamping studies.17-19 HOMA-IR is a utile method to find insulin opposition in epidemiological studies.17, 19, 20 Similarly, beta cell map can be assessed by the Homeostasis Model Assessment Beta ( HOMA-? ) .19 Several surveies have shown correlativity of IR with WC and WHR and these patients are at hazard for developing complications like indispensable high blood pressure, type 2 Diabetes, and cardiovascular disease.8 Each addition of 15 centimeter in the WC is associated with an addition of the hazard hyperglycaemia and IR ( 65 % and 123 % , severally ) . The cut-off points that better discriminated work forces and adult females, with and without IR, were 105 and 91 centimeter, with a sensitiveness of 62 % ( 95 % assurance interval [ CI ] , 46-77 % ) and 71 % ( 95 % CI, 54-85 % ) , and a specificity of 72 % ( 95 % CI, 66-78 % ) and 68 ( 95 % CI, 63-73 % ) , respectively.21 Prevalence of corpulence and fleshiness is high in type2 diabetes. This has been reported at 10.4 % and 79.4 % respectively.22 One survey demonstrated high prevalence of insulin opposition and impaired glucose tolerance associated with organic structure bole fat, among corpulent non-diabetic striplings. Insulin opposition was positively correlated with organic structure bole fat ( R = 0.457 ; P = 0.001 ) , BMI ( r = 0.417 ; P = 0.003 ) , organic structure fat mass ( kilogram ) ( r = 0.386 ; P = 0.006 ) and organic structure fat per centum ( R = 0.285 ; P = 0.047 ) . Furthermore, there was a negative correlativity between HOMA-IR and thin organic structure mass.7 The principle of this survey is that non much research work has been done on insulin opposition in Pakistan, and maintaining in head the part of insulin opposition to the development of complications, it is indispensable to find its prevalence which will enable us to step in at an early phase to forestall such complications. Besides with increasing figure of fleshy and corpulent patients and association of fleshiness with insulin opposition and development of complications, it is imperative to step in at an early phase and forestall the associated morbidity and mortality.AimTo find the correlativity of insulin opposition with organic structure mass index and waist hip ratio in patients of type 2 diabetes mellitus.Operational DefinitionHomeostasis Model of Assessment of Insulin ResistanceBody Mass IndexBMI = Mass ( kilogram ) / ( Height ( metres ) ) 2Material and MethodStudy design: Cross-sectional Study. Puting: Medical Unit II, Civil Hospital Karachi. Duration of survey: Minimal six months after blessing of outline. Sample size: Using correlativity of BMI and insulin opposition of 0.417, presuming correlativity of insulin opposition and WHR of 0.28, assurance interval of 95 % and power of survey 90 % , the sample size is calculated as 100 topics. Sampling technique Non-probability back-to-back sampling. Sample choice Inclusion standards: All patients with Type 2 Diabetes Mellitus.

An Idealized Model in Physics

An Idealized Model in Physics I once heard an acronym for the best pieces of physics advice I ever got: Keep It Simple, Stupid (KISS). In physics, we are typically dealing with a system that is, in reality, very complex. For an example, lets consider one of the easiest physical systems to analyze: throwing a ball. Idealized Model of Throwing a Tennis Ball You throw a tennis ball into the air and it comes back, and you want to analyze its motion. How complex is this? The ball isnt perfectly round, for one thing; it has that weird fuzzy stuff on it. How does that affect its motion? How windy is it? Did you put a little bit of spin on the ball when you threw it? Almost certainly. All of these things can have an impact on the motion of the ball through the air. And those are the obvious ones! As it goes up, its weight actually changes slightly, based on its distance from the center of the Earth. And the Earth is rotating, so perhaps that will have some bearing on the relative motion of the ball. If the Suns out, then theres light hitting the ball, which may have energy repercussions. Both the Sun and the Moon have gravitational effects on the tennis ball, so should those be taken into account? What about Venus? We quickly see this spiraling out of control. Theres just too much going on in the world for me to figure out how all of it impacts on me throwing the tennis ball? What can we do? Use in Physics In physics, a model (or idealized model) is a simplified version of the physical system that strips away the unnecessary aspects of the situation. One thing that we dont typically worry about is the physical size of the object, nor really its structure. In the tennis ball example, we treat it as a simple point object and ignore the fuzziness. Unless its something were specifically interested in, well also ignore the fact that its spinning. Air resistance is frequently ignored, as is wind. The gravity influences of the Sun, Moon, and other heavenly bodies are ignored, as is the impact of light on the surface of the ball. Once all of these unnecessary distractions are stripped away, you can then begin focusing on the exact qualities of the situation that youre interested in examining. To analyze the motion of a tennis ball, that would typically be the displacements, velocities, and gravity forces involved. Using Care With Idealized Models The most important thing in working with an idealized model is to make sure that the things youre stripping away are things that are not necessary for your analysis. The features that are necessary will be determined by the hypothesis that youre considering.   If youre studying angular momentum, the spin of an object is essential; if youre studying 2-dimensional kinematics, it may be able to ignore it. If youre throwing a tennis ball from an airplane at high altitude, you may want to take into account wind resistance, to see if the ball hits a terminal velocity and stops accelerating. Alternately, you may want to analyze the variability of gravity in such a situation, depending on the level of precision you need. When creating an idealized model, make sure that the things youre eliminating are traits that you actually want to eliminate from your model. Carelessly ignoring an important element isnt a model; its a mistake. Edited by Anne Marie Helmenstine, Ph.D.

Free Example of Argumentative Essay Rationalization theory is a powerful tool in putting long-range historical processes into perspective. The overriding ethos of industrial society-a cost-accounting mentality and the urge to build and control institutionshelps explain both the ethos of urban revivalism and the ethos of religious television. The ethos of both reflects the historical periods in which they developed. The ethos of revivalism and its use of appropriate means fits into an era dominated by industrial capitalism; the ethos of religious television and the notion of God's technology fits neatly into the postindustrial era, in which technology will "solve" all our social problems. As part of the business and entrepreneurial tradition, televangelists are businessmen for the Lord. They are eager to seize available opportunities to sell the gospel through mass communications. They pursue their goals of winning souls and building teleministries without hesitation, never questioning the appropriateness of using telev ision to do so. Neither are they encumbered by denominational deliberations. Rather, their concern is how to use television effectively. Schooled in pragmatism, televangelists know how to reach the individual Christian, offering hope and love to ameliorate fear and anxiety and, perhaps more importantly, offering membership into their television communities as a means of acknowledging the viewers' importance to them. In addition to the use of any appropriate means to win souls, members of the electric church value the dynamics of a free-market economy in modern life, including competition for religious beliefs. They believe that the free market will recalibrate the economic system and the religious system and, because of this strongly held mindset, they claim to oppose federal government regulation and intervention. Despite their rejection of Darwinism, they equate successful competition with worthiness and confidently compete with other religious groups and organizations. One way they compete is by reaching out to those evangelicals who are nonaffiliated or disenchanted with their congregations. Another is by competing for the same, already established audience, as illustrated by Oral Roberts fighting to maintain his top-ranked position but losing to Jimmy Swaggart, or the fortunes of Rex Humbard and James Robison waning, but those of Pat Robertson and Jim Bakker rising.

They hire new technical-professional staff. They contrive events to get their names in the papers and on television. They diversify their business activities by offering hotel facilities, special tours of their studios, schools for the children of viewers, and, in one case, a theme park. In short, they engage in the business of staying in business, and, in the process, lose their uniqueness and mystery.

In the case of prayers from religious leaders, they believe that God, through the priests, heals the sick. The priests anoint and give Holy Communion to the sick in the health facilities. This act benefits the sick since they receive both spiritual and medical healing. The implication of this belief for healthcare is that the healthcare providers believe that their work is to treat patients, but God is the one who heals the sick. Additionally, Roman Catholics through the scriptures of the Bible firmly believe and are hopeful that there is life after death (Molewyk et al., 2005).
