Cari’s Story Essay

How could an infection in Cari’s nasal passages and pharynx spread into her sinuses? An infection will spread because the pharynx, larynx and sinuses are all connected, so the infection is going to spread to the sinuses and the surrounding areas. What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing? The cough reflex is a deep and long inhalation that is followed by the closing the glottis, this causes a strong exhalation that will push the glottis open and sends the air through the respiratory passage. The coughing occurs when a foreign body is in the larynx, trachea or the epiglottis. Cari is coughing because the mucous and fluid buildup in her lungs and her body is to get rid of it. Which structures found in the terminal bronchioles and alveoli normally would protect Cari’s lungs from infectious pathogens and particulate matter? The alveolar macrophage protects her lungs because they wonder around the alveoli space and it collects dust, particles and debris. Cari does smoke and it has caused the cilia in her respiratory passage way to become paralyzed and then it secretes the excess amounts of mucus. The macrophages are sent to the lungs and it gets stuck in the mucus and it can’t fight off the pathogens. How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? Cari isn’t getting adequate oxygen because the pressure of fluid and the mucus buildup in her lungs. This is not allowing her lungs to expand so she can get the breath her body needs. The fluid buildup and the pressure are not allowing her oxygen to disperse to the areas it needs. How would Cari’s lung compliance (the effort required to expand the lungs) be altered as her alveoli fill with fluid due to pneumonia? The fluid in her lungs makes it hard to expand because the fluid makes the alveoli sticky and it can’t expand and open. How would fluid in Cari’s lungs affect her total lung capacity? Cari’s lung capacity would go down due to the fact that the air space is being taken up by the fluid in her lungs. How does the elevation of Cari’s respiratory rate alter her minute ventilation? Cari’s respiratory rate will increase her minute ven tilation. Normal blood oxygen saturation levels are greater than 94 percent; Cari’s blood oxygen saturation levels are greater 90 percent at the time of her exam and an initial arterial blood gas analysis done when  she was admitted to the hospital revealed her arterial Po2 was 54mmHg. How do these clinical findings relate to the internal respiration in Cari’s body? Cari’s oxygen saturation level was 90% and the Po2 of mmHg would show that her arteries are having too much oxygen. A normal resting mmHg is 40% and exercises lower Po2level. A normal resting oxygen level is 94%. Which of the symptoms Cari has described are due to the lack of oxygen and reduced oxygen exchange at her tissues? Cari said she is â€Å"panting like a dog† is due from the lack of oxygen and t reduces her oxygen exchange. As Cari’s Pco2 rose, how was the oxygen-carrying capacity of hemoglobin affected? The oxygen carrying of hemoglobin volume with the rise of Pco2 will decrease since the Co2 will take O2’s seat. How would you have expected Cari’s decreased Pco2 and alkaline blood pH to have affected her breathing? Cari’s pH and Pco2 will decrease and her rate of breathing will also be decreasing. How would administration of oxygen enhance Cari’s central drive to breathe? Cari would be able to breathe better when oxygen was administered to her. Which anatomical structures in Cari’s respiratory system were initially involved? The structures involved are the trachea, nasal, pharynx, and larynx, and the lungs. Why was Cari plagued with a chronic smoker’s cough? Cari is plagued with a chronic smoker’s cough because she has a 20 year history of smoking. Which damaging effects of tobacco smoke led to Cari’s impaired respiratory defense mechanisms? There are damages to the epithelial with those damages comes the body’s repair process. How did the pneumonia affect Cari’s lung function? Cari’s was having problems getting adequate oxygen, because of the fluid in her lungs. The pneumonia is an infection from bacteria that can affect the body, because of her smoking it made it hard for her lungs to get air.

Encryptions Essay

In this report I have discussed that the encryption technology is necessary for citizens to protect their privacy and security when using computer networks. Otherwise, medical records, credit card numbers, trade secrets, as well as personal communications relayed over computer networks are not safe from prying eyes. Also I have presented an arguments in favor of encryption that it offers a method of denying access to adversaries, improves security by protecting against spoofing, offers a device for recovering costs plus imposing fees and protects private DGPS providers from government competition. Furthermore I have also explained some arguments against encryption that to put into practice it would potentially weaken U. S. leadership in GPS by encouraging international augmentations that lacked encryption, need a multifaceted key management infrastructure, need a major redesign and development endeavor, causing delays and escalating costs to the government, make innovative safety risks if the key management system failed, mainly in an emergency. Thus the transaction costs imposed by encryption would have to be balanced against the benefits expected. Introduction Encryption software enciphers data sent over computer networks, in order that merely people with special information for instance a secret key can read the plaintext of the message. The key is a string of numbers. The longer the string, the harder it is to break. In January 2000 the Department of Commerce announced new encryption export policy. Under the new system, U. S. companies may export any encryption product around the world to private-sector end users or commercial firms after a one-time technical review. Encryption products that the Bureau of Export Administration (BXA) determines fall into the category of â€Å"retail encryption commodities and software† can be exported to anyone. In determining which products fit the meaning, the BXA will think about the product’s function, sales volume, plus distribution methods. Publicly available source code may be exported with no technical review. The relaxation of export controls on products planned for e-commerce merchants, financial institutions, and others is a step in the right direction. However problems remain. First, the â€Å"publicly available† or â€Å"sales volume† tests doom U. S. companies to lag behind foreign cryptographers in offering innovative encryption products. No pioneer product is so far â€Å"publicly available† or has a large sales volume. The revised encryption rules therefore still permit foreign cryptographers to take the lead in developing new crypto products. Second, any encryption products have to be submitted for a technical review before release. This means that encryption will not be built into most mass-market products. For instance, it would make sense to construct an encryption option into a standard e-mail program. However, building encryption into an e-mail program would mean that the e-mail program could not be exported without a long, uncertain technical review. To stay away from the technical review, companies are probable to leave out the encryption function. Network security will carry on to suffer for the reason that encryption will not be built into mass-market products like e-mail or word processing programs. Third, the condition that encryption products be submitted for review before release violates the First Amendment. In April 2000 the Sixth Circuit Court of Appeals established that encryption source code is speech protected by the First Amendment. The obligation that encryption products be reviewed prior to release is a â€Å"prior restraint† on speech. Those problems with encryption export controls are extensively recognized. The alternatives to the controls, though, have barely been examined, with the exception of â€Å"key escrow,† or â€Å"key recovery. † Mainly, it is wrong to bar anyone from using nonescrow encryption to communicate when he has done nothing wrong. Demands for obligatory key escrow constitute an unparalleled power grab on the part of law enforcement officials. The police have always had the right, restricted by the Fourth Amendment, to intercept private communications and read them, if they could. The police have never had the right to demand that people change the language in which they communicate to make themselves easier to understand. There are further alternatives to encryption regulations for law enforcement. They comprise increased use of informants and other surveillance technologies for instance the planting of physical bugs or devices such as Tempest, which allows law enforcement to read the screen of a computer through walls or doors. Encryption export controls must be lifted without qualification. GPS-related cryptographic A GPS-related cryptographic system can be used for two reasons: denial of the signal to unauthorized users, as well as protection of the message itself to, prevent alterations or the creation of a substitute message. The former makes a vital portion of the message unavailable to non-authorized users. In military schemes preservation of a one-sided advantage may be of interest; in a commercial setting the capability to eliminate nonpaying users is essential to collect revenue. Authenticating the message through use of an encrypted signature block that may both authenticate the sender of the message and confirm the contents is consistent with application in the civil government sector, where making sure integrity of the message is significant. In a DGPS context, encryption might be inserted at one of several points in the transmission of the signal to the user. Encryption may defend the uplink in a satellite relay, the original messages to the satellite, also the command functions on the satellite. Or encryption might protect the signature region of a message that points out its authenticity and the integrity of the main message payload. A third option might be to encrypt the complete message. Other variants comprise encrypting merely selective portions of the message. Throughout the hearing, there was disagreement over how multifaceted the key management infrastructure needed to be. The underlying policy question was how protected and dependable the encryption must be. As Dr. Denning put it, â€Å"in any encryption, something must remain secret. † (Bruce Schnier, 1994). For some proprietary algorithms, no keys need to be distributed, and this is generally adequate for commercial systems for instance cable TV and the DGPS providers. If an open algorithm is used, keys and a related key management system are required to gain international acceptance. The desired future of electronic, over-the-air rekeying is not yet here. In the case of military systems, both keys as well as classified algorithms are used. There are a number of technical approaches that might be taken to encrypting the signals for local- and wide-area DGPS applications using private-key and Public-key encryption schemes. A few schemes involve over-the-air â€Å"rekeying† devices to enable/disable the capability of specific units to receive messages. Other schemes involve comparatively simple authentication mechanisms that would not have to be tied to individual units and would depend on the capability to avert alteration or forging of a message. As one would think, trying to deny signals to end-users is an involved process from the point of view of managing keys and of keeping track of which unit belongs to which person or group. Nonetheless, if the goal is to permit control of the use of a signal rather than, say, prevention of reception of the signal by cutting of transmissions in a given area, then one is forced to these more elaborate schemes. (Simon Garfinkel, 1995) The objective of encryption must be decided before selecting a particular approach. If the main goal is authenticating the message and preventing false messages, there is no need to go to the expense and intricacy of a system that refutes the fundamental message by encrypting the entire message stream. If encrypting the stream in the future is desired, it may be appropriate to use a more complicated scheme as long as the possible future benefits are expected to offset related costs and possible opposition. The intricacy of denial-focused approaches plus the apparition of selectively controlling the signal will make incentives for alternative standards and systems outside of U. S. control.

Zoo Activity - Essay Example Although the other placental mammals had a tendency to live in grasslands, marine and other environments, the adaptive niche for the primates was trees. According to the arboreal hypothesis, this provided numerous challenges and opportunities such as depth perception and binocular vision, climbing by utilising prehensile hands and feet instead of claws, varied diet resulted to omnivorous adaptation and longer life span, increased their intelligence and more elaborate social system which they required to cope with. 1. White-handed gibbon (Hylobates lar) White-handed gibbons are diurnal, natural aerial acrobats and are fairly awkward on the ground. The have long fingers and limbs, special thumbs and strong arms are specialised to the arboreal life in their forest home. Stewart and Harcourt (16-19) noted that as they swing from limb to limb they usually hook their fingers lightly over the branches. When they meet a break in the trees, they have the capability to leap to the next tree up to 25-30 feet away. Their intelligence in locomotion makes them quick and efficient when moving from feeding to escaping from predators. The morphology and behavior of white-handed gibbon With regard to its morphology, the white-handed gibbon lacks a tail and has a throat sac located beneath the chin. The average body mass for an adult is around 5.7 kilograms, and for the female it is around 5.3 kilograms.

Famous Filmmaker Robert Rodriguez Essay Example | Topics and Well Written Essays - 1250 words

Famous Filmmaker Robert Rodriguez - Essay Example While Rodriguez today has achieved tremendous critical acclaim this was not always the case. Rodriguez started from humble beginnings and in-large part carved the path for his own success. This essay examines Chicano filmmaker Robert Rodriguez. Robert Rodriguez is Chicano American, with both of his parents -- Rebecca Villegas and Cecilio G. Rodrà ­guez – being of Mexican descent. While many people struggle to discover their path in life, from a young age Robert Rodriguez knew he was interested in artistic production. In his autobiography, Rodriguez indicates that â€Å"I associate my earliest memories with the movie theatre† (Rodriguez, p. 1). Here there is the recognition that Rodriguez formative youth was occupied by his life at the movie theatre. One considers the understanding that oftentimes foreign languages are difficult to learn late in life. Rodriguez early youth obsession with the cinema seems to have profoundly affected his cognitive development. Rodriguez indicates that his mother took him to the Olmos Theatre in San Antonio and he would watch classic films (Rodriguez, p. 1). While many mothers allow encouraging their children to read books, Rodriguez mother was unique in that she encouraged the future filmmaker to watch these classic films. Rodriguez’ ability to watch classic films was a great benefit for the filmmakers, as the Olmos Theatre was a rare art-house theatre. Rodriguez access to these films then further shaped his development as a filmmaker. Rodriguez first great break as a filmmaker came after he filmed the short ‘Bedhead’. This short film featured a girl and her brother. The film had a very simple plot, with the boy having disarranged hair. The boy’s disheveled hair causes him to come into a number of conflicts with his sister, as her fastidious behavior is at odds with the boy’s awkward appearance.

Answer Each of the 5-Questions Which Will Be Uploaded - Essay Example In addition, the important American value of personal space and freedom of movement are likewise reflected and embodied in the sports car, as the defining cultural values for their consumption by Americans (Ikerd). For watches the factors of nonverbal communication that are key from a marketing perspective relate to the communication of wearer personality, values, hobbies, and earning capacity and wealth. There is substantial segment of the market for instance that caters to the luxury watch as an important non-verbal signal of wealth and prestige, and personality and values are related to the way watches that are marketed for more pragmatic and more efficiency-focused individuals reflect those aspects in non-verbal ways, through an emphasis on functionality, on attributes such as durability and technical capabilities. A market segment meanwhile buys watches based on attributes such as personal style and fun, and those are also ideally reflected in the kinds of fun watches that they buy. Those non-verbal communication cues are therefore relevant to this segment of the market (Klara). For laundry detergents on the other hand, the nonverbal factors of communication that are most relevant relate to cleaning power, efficiency, care of clothes and hands, and brand power to a certain extent, as well as price. These factors are embodied either explicitly or implicitly in discussions about strategies for the Tide brand for instance (Ng and Ziobro). One is the admiration of nature, where the current and emerging markers tend towards that over the contrary value of the conquest of nature, which is marked as the traditional American value. The book got this wrong because one can argue from the lack of more vigorous concern for climate change implies that more people still prefer overcoming nature to admiring it and fixing its long-term problems. Two is performance versus

Childhood Obesity as an Epidemic in America Assignment

Childhood Obesity as an Epidemic in America - Assignment Example Many parents have the habit of feeding their children with fatty and sweetly foods. They wanted to see their children in good health. Overweight is often visualized by them as the symbol of health. But in reality, it is not so. Even though parents are keen on feeding their children with food, they are not so in forcing the children to engage in some physical workouts to shed the excessive calorie intakes. Exercise plays an important role in reducing childhood obesity. Karnik & Kanekar pointed out that â€Å"Lack of playtime, little or no physical education at schools, video games and excessive TV viewing time are proposed as the major cause of the childhood obesity epidemic† (Karnik & Kanekar, p. 4). The government should implement compulsory physical education at school levels. Along with academic subjects, physical education and exercises should be made the part of the curriculum. 2. HIV, the virus that causes AIDS, passes through breastfeeding to 1 in 7 infants born to HIV-infected mothers. However, in developing countries, some HIV-positive women are advised to breastfeed. Explain this advice, considering what you know about the benefits of breastfeeding.   â€Å"Even in high-income countries, breastfed babies are less likely to become ill than those given replacement foods†(HIV & Breast Feeding). However, HIV mothers are normally advised to stay away from breastfeeding to prevent the spreading of HIV. It should be noted that breastfeeding is one of the major activities which spreads HIV among infants. â€Å"Under exceptional circumstances, and after seeking expert professional advice on reducing the risk of transmission of HIV through breastfeeding, a highly informed and motivated mother might be assisted to breastfeed† (HIV & Breast Feeding). The merit of breastfeeding against the possibility of spreading HIV is taken into the  consideration while the authorities ask the HIV mothers to breastfeed their children.

Nietzsche's Preface (no.7) - Essay Example d beginning of various social and philosophical beliefs through an attempt to account for the scope, totality or breadth of ideology in the time period provided as opposed to being focused on a singular dominant ideology (Ransom 62). Additionally, a genealogy attempts to see beyond the ideology that is in question, for conditions the genealogy possibility. Genealogy developed as a continued works of Nietzsche. Fredrick Nietzsche on the genealogy of morals criticized the "the genealogists" and proposed a historic philosophy to be used in order to effectively critique the modern mortality through supposing that the genealogy of morals did develop into the current form through the power relations. The philosophy of Nietzsche is characterized as genealogy because of his use of genealogy in the genealogy of morals (Ransom 56). This paper explores the main characteristics of the genealogical method and how helpful this method is in evaluating and reevaluating peoples moral prejudices and i n finding their origins. The essential characteristics of the Nietzsches genealogical method includes identification of the area of designated study, drawing up of the dispositif that shows the relationship to area of designated study for the many phenomena that constitutes it, the exposures through effective history of the destabilising along with discontinuous discursive and other elements that are involved in the production given problem with its associated truths, consequent rejection of searching for the fixed hidden meaning relevant to the problem or for the conscious authorial intension, and a combination of meticulous scrutiny and detachment in the analysis of the given textual and non-textual discursive and manifestation of the problem (Ransom 82). The main project for Nietzsches in the Genealogy is questioning the value of morality. Nietzsche argues that peoples current morality is born out of hatred, and resentment felt towards anything that was healthy, powerful, or

Strategic Business Management and Its Comparison to the Case of Research Paper - 1

Strategic Business Management and Its Comparison to the Case of iCreative - Research Paper Example The researcher states that for expansion of business through internal venturing and joint ventures, iCreative requires managers and leaders who possess strategic leadership skills along with market intellect and cultural awareness of foreign markets. Being an entrepreneur and introducing a new concept in the market requires a different approach altogether than running family-owned businesses or other established organizations, be it a company or a partnership. Where every organization model requires a different leadership approach, entrepreneurship demands innovation and creativity. Entrepreneurial leaders are required to be dissatisfied with the status quo and should have the ability to question imperfections and present a better alternative. For this purpose, learning ways of existing businesses and modifying them effectively is the gist of entrepreneurial leadership. Entrepreneurial leaders need to have flexibility in their approach and ability to learn continuously. Furthermore, these leaders are expected to have authenticity in their tone when they communicate. Such leaders not only share their insight but also have the humility to encourage their peers and subordinates to share their views. Since an entrepreneurial model is never perfect in the inception, therefore feedbacks and ideas of a team could help this new venture. Entrepreneurial leaders are also expected to have a vision and ability to examine their organizations at different levels of businesses. It not only includes operational and strategic management levels but also involves capability of identifying gaps between existing and desired efficiency and effectiveness. Entrepreneurs are provided with a huge amount of advice and negative feedbacks having the critical effect on business performance.

Marketing trend (Internet and online marketing) Assignment - 1

Marketing trend (Internet and online marketing) - Assignment Example Internet marketing reduces the overall marketing cost of a firm because a firm can utilize emailing as a marketing tool, which costs fairly lower than the direct mail (McCarthy, 2011). In addition, through e-marketing, a business can expect immediate impulsive response from its target market by them clicking on the website. In this manner, the message of the company reaches a large number of consumers in less time, as well as at low cost (Arnold, 2009). With regards to consumers, on the other hand, internet marketing reduces the cost of them going to the market to look for products. However, they can only do this if they have access to the internet (Jenkins, 2012). They also need various assets such as credit cards to purchase some goods over the internet. Internet or online marketing affects a business by providing it with a variety of advantages. It has turned into a power tool and organizations can use it to make their 24 hours presence throughout the world (Jenkins, 2012). Consumers also have the opportunity of shopping online, and inquire on the services and products at any time. With regards to customers, it is easy for them to leave their queries and comments through email or the feedback form (McCarthy, 2011). The firm’s representatives can also answer the queries instantly or in a short time period. This opportunity has helped customers build up close association with companies and this expands business. Internet marketing has brought about a rise in market competition since it has become easy for many firms to advertise successfully online by taking advantage of the low budgets (McCarthy, 2011). It is essential that firms, prior to entering an online market, be well aware of the potential impacts of internet marketing, and they should plan their strategies to face the online marketing barriers before going online. According to research, a majority of consumers, 60%, show reluctance when it come to purchasing goods over the internet. They opt
