Case - Essay Example Through the bill of sale, Riley transferred to Thelma one-half undivided interest in seven units of the property. Through the assignment, Riley also assigned one-half undivided interest in the lease property. This interest included the right of survivorship in favor of Thelma for the other half interest held by Riley. The consideration for both of these agreements was $1.00. The two separated and Thelma went to court seeking to end their domestic partnership as well as enforce the two agreements. According to Riley, the two agreements lacked consideration. On the other hand, Thelma argued that their pending engagement and the amount that she had deposited into their joint account was sufficient consideration for the enforcement of both agreements. The trial court upheld the agreement and divided the property in accordance with the sale agreement as well as the assignment. Riley was not satisfied with the decision of the trial court and went to the Court of Appeal of Tennessee to appeal against the decision of the trial court. Reasons: the court looked at the two agreements and examined them to check whether the four elements that a valid contract should fulfill were present. These four elements are offer, acceptance, consideration and intention to enter into a legally binding contract. The court in looking at the element of consideration, ruled that it was adequate. In a contract, consideration need adequate but sufficient. The court stated that consideration however small is sufficient consideration. It is the responsibility of the seller to seek Consideration is the element that distinguishes a gift from a sale and in this circumstance; the court held that the detriment suffered by the defendant in this case does not have to be equal to the responsibility that is assumed. So long as there was no fraud in passing the interests, the court could

The Gold Rush Essay Example | Topics and Well Written Essays - 500 words

The Gold Rush - Essay Example The gold rush seemed to spell the beginning of the end for the people who lived in California when gold was found, it was also the beginning of equal rights for others who had long been oppressed by these same oppressors. There were several people already in California when gold was discovered. In addition to the white men that were moving into the west as a result of the Mexican-American War, there were plenty of Mexicans already living on the land of California, colonists sent by Mexico and Spain called Californios. Although many of the Mexicans who settled in California to work the ‘southern mines’ were experienced miners in the same sort of climate as they encountered in California, their expertise and success was resented by the white colonists. â€Å"In a little over two years, Americans came to resent the fact that foreigners -- particularly those from a country the United States had just defeated in war -- were making it rich off land that they now considered exclusively theirs† (Chavez, 1998). As a means of ‘evening up’ the playing field, the white settlers struggled to gain control of the legal institutions and thus bring about laws that favored them while s ignificantly reducing the resources and recourses available to the Mexicans or people of non-white descent. Another group of people had also been living on California land in the mid-1800s. They made up a variety of tribes and distinctly separate cultural groups, but history has clumped them together under the common term Native Americans. These people had long lived off of the fruits of the land, fitting themselves within the rhythms of the natural seasons and placing value on things that actually benefited them directly, such as food, clothing, shelter and workable metals or stone. Materials such as gold had little value to them because it was too soft to be dependable and did not provide any other direct benefit. However, these Native Americans

Research Methods - Assignment Example However, though this is a great advantage for patient diagnosis, the risks associated with these practice for both the patients and the staffs who operates the radiology equipments have increased. The exposure of the patients to longer duration of fluoroscopy and higher doses of radiation are the major risks associated with the radiation modalities (Slechta, & Reagan, 2008 p302). Consequently, there is a greater need for the medical staff to adhere to the radiation protection and safety practices, to secure the patients, as well as the staffs themselves from the negative effects of radiation (Furlow, 2010 p440). Since most of the data was collected through the application of quantitative research designs, the information obtained is more reliable. However, the dependence on questionnaire as the instrument of data collection may not have given precise information regarding the area of study, as truthfulness of the information given cannot be easily verified. Thus, more use of interviews and observation, which allows the researcher to be in touch with the respondents, would be more appropriate for the

Concept tools Assignment Example | Topics and Well Written Essays - 250 words

Concept tools - Assignment Example In the present study, clinical judgment will be measured by measuring how nurses notice certain data on the patient, how they make sense of the data, and how they intervene in the patient’s issue. An effective measuring tool for clinical judgment that will be employed in the current study is Tanner’s Clinical Judgment tool. In this study, the tool will be used in a pre and posttest design for using clinical judgment in employing JNC guidelines in treating hypertension. Its validity, which is the other thing that makes it suitable for the current study, is underpinned by its wide use in different studies. The results of the tool are credible and this is seen in the reliability of the results of the studies that employed it previously. A limitation with Tanner’s Clinical Judgment model is that it might not capture some aspects of a patient’s condition (Modic, 2013). In summary, Tanner’s Clinical Judgment Model is the appropriate tool to use in the current study because it conceptualizes clinical judgment holistically and does not have many limitations that would hinder its accuracy. The tool has been validated by multiple studies. Ashcraft, A., Opton, L., Bridges, R., Caballero, S., Veesart, A. & Weaver, C. (2013).

Tylenol Exigencies Business Research Paper Example | Topics and Well Written Essays - 2000 words

Tylenol Exigencies Business - Research Paper Example This in turn, marked the beginning of the company’s integrity in baby business (â€Å"Our Timeline†, n.d., para.3). The company’s efforts to help through provision of relief goods in the aftermath of disasters in the 1900 and 1906 also did a lot to carve its name in the industry. At present times, Johnson & Johnson is in partnership with 250 companies and holds offices in 57 countries distributing their goods in over 175 nations (Johnson & Johnson Corporate, n.d., para.3). In the year 2011, the company’s pharmaceutical sales approximated to $65 billion. Tylenol, McNeil Laboratories & Johnson & Johnson Acetaminophen is the active ingredient in Tylenol. It is widely used for relieving pain and reduction of body temperature for fever. The sales team of McNeil Laboratories came with the term Tylenol by choosing letters from its chemical form N-aceTYL-p-aminophENOL (West, 2009). McNeil Laboratories founded by Robert McNeil was the first to manufacture Tylenol i n 1955 as a prescription drug elixir for children. There was an ongoing issue during that time about the harmful effects of then widely used drug, aspirin. McNeil Laboratories marketed Tylenol as the benign alternative to aspirin (West, 2009). It was in 1959 when Johnson & Johnson acquired McNeil Laboratories and the same year marked Tylenol as a prescription-free drug. From then on, Tylenol has been one of Johnson & Johnson’s most widely sold and most profitable product, bringing an average year to year profit share of 33% (Griese, 2001). The 1982 Tylenol Tampering Widespread scare enveloped the nation when seven deaths have been attributed to Tylenol ingestion in September of 1982. Two off-duty firemen unintentionally hypothesized the connection of Tylenol while listening to police radios and talking about the supposedly mysterious deaths (Kaplan, 2005). Among the victims were a 12 year old student Mary Kellerman; three family members Adam Janus, his brother Stanley and Sta nley’s wife, Theresa, aged 27, 25 and 19 respectively; 27 years old mother of four, Mary Reiner; stewardess Paula Prince, 35 years of age; and 31 years old Mary McFarland. These victims have died within hours after taking Tylenol due to the cyanide content of the capsules, which was stronger by 10,000 times to the cyanide dose the human body can take (Kaplan, 2005). Johnson & Johnson acted promptly. At that time, nobody thought of such tragedy. These murders became the first of its kind. It was revealed in the investigations, that the capsules were tainted by cyanide through the act of an intent person because no specific evidence can link that the Tylenol capsules were laced by cyanide during manufacture (Kaplan, 2005). At the turn of events, Johnson & Johnson decided to put out a major recall for all the Tylenol capsules in the country. The manner in which Johnson & Johnson handled the controversy is regarded by professionals â€Å"to be one of the best in the history of p ublic relations† (Kaplan, 2005). In Griese’s book (2001), she cited the Tylenol tragedy as a befitting example on making the right decisions during time of crisis. Griese enumerated eight steps as guidelines in decision-making. The first step after the identification of the situation is to conduct research. The company McNeil Consumer Healthcare under Johnson & Johnson, which is

Failure Of Materials Essay Example for Free

Failure Of Materials Essay Failure of materials is an analysis in engineering world, to approach and determining about how and why a materials has failed, like iron bar, why it can crocked or porous. Some general causes of failure are structural leading, wear corrosion and latent defects. Failure of materials must be known by an engineer, safety is the first word when engineer working building structure. They can not take random about materials that is used. They must know strength, flexibility, and endure of materials. For adding, with developing and updating software or research that had be done by company, we’ll more easy to know the characteristic of materials that we use. TYPICAL OF FAILURE OF MATERIALS Fatigue Failures Metal fatigue is caused by repeated cycling of the load below its static yield strength. It is a progressive localized damage due to fluctuating stresses and strains on the material. Metal fatigue cracks initiate and propagate in regions where the strain is most severe. The process of fatigue consists of three stages Initial crack initiation, Progressive crack growth across the part, and Final sudden fracture of the remaining cross section. Corrosion Failures Corrosion is chemically induced damage to a material that results in deterioration of the material and its properties. It is most coming from environment. Corrosion is normal, it is can not be removed, but can be minimized with several strategy like proper choice of material, design, coatings, and occasionally by changing the environment. Various types of metallic and nonmetallic coatings are regularly used to protect metal parts from corrosion. If corrosion can be minimized, materials be able to use and more advantage. Ductile and Brittle Metal Failures Ductile metals experience observable plastic deformation prior to fracture. Brittle metals experience little or no plastic deformation prior to fracture. At times metals behave in a transitional manner partially ductile/brittle. Ductile fracture is characterized by tearing of metal and significant plastic deformation. The ductile fracture may have a gray, fibrous appearance. Ductile fractures are associated with overload of the structure or large discontinuities. High Temperature Failures In physics theory, when a materials is being warm, they will expand than original size. We know about boilers, gas turbine engines, and ovens are some of the systems that have components that experience creep.   An understanding of high temperature materials behavior is beneficial Failures involving creep are usually easy to identify due to the deformation that occurs. Failures may appear ductile or brittle. While creep testing is done at constant temperature and constant load actual components may experience damage at various temperatures and loading conditions. in evaluating failures in these types of systems. High temperature progressive deformation of a material at constant stress is called creep. High temperature is a relative term that is dependent on the materials being evaluated. Liquid Metal   and Hydrogen embitterment Failures   Liquid metal embitterment is the decrease in ductility of a metal caused by contact with liquid metal. The decrease in ductility can result in catastrophic brittle failure of a normally ductile material. Very small amounts of liquid metal are sufficient to result in embitterment. The liquid metal can not only reduce the ductility but significantly reduce tensile strength. Liquid metal embitterment is an insidious type of failure as it can occur at loads below yield stress. Thus, catastrophic failure can occur without significant deformation or obvious deterioration of the component. Hydrogen embitterment failures are frequently unexpected and sometimes catastrophic. An externally applied load is not required as the tensile stresses may be due to residual stresses in the material. The threshold stresses to cause cracking are commonly below the yield stress of the material. Very small amounts of hydrogen can cause hydrogen embitterment in high strength steels. Common causes of hydrogen embitterment are pickling, electroplating and welding, however hydrogen embitterment is not limited to these processes. There are causes of materials failure, but not disease that not have medicine. Every materials that we use have a protection, protection come from our knowledge about characteristic of materials as chemical composition, using guide or calculation and appointment the materials for our structure. Addition, many factory,   metal – producing majority, also publish list of their product that have content about characteristic ( strength, elasticity, endure and treatment). Bibliography Omens, J.

Corrosion Properties of Al-B4C Composites

Corrosion Properties of Al-B4C Composites Abstract[SM1] The influences of adding B4C particles on corrosion behavior of Al-2wt.% Cu alloy was studied in 3.5 wt.% NaCl solution at room temperature using linear and cyclic polarization, immersion test and Electrochemical Impedance Spectroscopy (EIS).[SM2] Nano-composites reinforced with 2, 4 and 6 wt. % B4C were produced through mechanical milling and tested to explore the B4C contents effects on the corrosion properties. [SM3]Influences of the grain size were also studied comparing the coarse-grained and milled Al matrix. Results revealed that the corrosion resistance of Al matrix decreases by reducing the particle size. Sample with 2wt.% B4C showed best corrosion resistance amongst all. Key words: Mechanical milling, Nano-composite, Al, B4C, Corrosion Introduction Metal Matrix Composites were remained the focus of attentions in aerospace, automotive and military industries in recent years. These materials offer several advantages including the high strength to weight ratio, excellent wear resistance and high stiffness compared to the original alloys. The commonly used reinforcing materials are; silicon carbide, aluminum oxide and boron carbide. Due to density differences between the reinforcements and the matrix materials, segregation has been found to be a major problem in producing metal matrix composites. Ball milling is considered to be an important technique for producing nano-crystalline composites. Growing interest for this technique is due to preparing materials with unique chemical, physical and mechanical properties. Ball milling process makes uniform distribution of reinforcement particles in the matrix, preventing the segregation which is commonly found in composites fabricated through other methods [1-4]. Effects of B4C particles as reinforcement materials on mechanical properties of aluminum base alloys are existed in the literatures, but studies on corrosion behavior for these composites are rarely reported. Corrosion behavior is a key parameter for assessing the applications of composites in marine environments. All in all, incorporation of the reinforcements into Al alloys increases the corrosion rate of composites in comparison with matrix. Primary corrosion initiation sites in MMCs[SM4] are dependent on electrical conductivity of reinforcement material, reinforcement volume fraction, intermetallic phases and corrosive environment. Grain size has also a major effect on corrosion behavior of the composites [5-9]. Present research aims at studying the corrosion properties of Al-B4C composites. The influence of different B4C contents on corrosion behavior of Al matrix composites was investigated. Coarse-grained Al matrix was also used to explore the effect of grain size on corrosion resistance. Experimental Al–2wt.% Cu and the nano-sized B4C particles were respectively used as matrix and reinforcements in fabricating the specimens. Besides a plain matrix sample, others were synthesized through mechanical alloying of the powder mixtures with 2, 4, and 6 wt.% of B4C. Ball milling was done by a planetary mill, equipped with two tempered steel vials containing Chrome steel balls (φ=20mm). The rotational speed and the ball to powder weight ratio were set at 300 rpm and 10:1, respectively. Milling process was performed at room temperature under argon gas (99.999%) atmosphere protection for 20h[SM5] to achieve steady state condition. Mechanically milled powders were then cold pressed and hot extruded with an extrusion ratio of 10:1 at 550à ¢- ¦C. Reference Al alloy sample was prepared from unmilled aluminum powder using similar pressing and extrusion processes. Electrochemical measurements including linear polarization, cyclic polarization, weight loss and electrochemical impedance spectroscopy tests were applied to 3.5wt.% NaCl solution at room temperature. Three electrodes system, including a working electrode, a platinum counter electrode and a silver-silver chloride electrode (Ag/AgCl) as [SM6]reference electrode were used. The exposed area of samples was polished to 1200 emery paper. Tafel tests were performed at a scan rate of 1 mV/s, from -2000mV to 500mV using a 273A Princeton Applied Research EGG model potentiostat/Galvanostat. Cyclic polarization measurements were carried out under conditions similar to Tafel test. After reaching to the 500mV point, scan direction was reversed. In order to find out the exact protection potential, scan rate of 0.5 mV/s was applied in reverse direction. Disc shape specimens (10mm in diameter and 3mm thick) were immersed in 3.5wt.% NaCl solution in atmosphere for 1, 3, 7, 14 and 28 days. Corroded samples were cleaned according to G1 standard, [SM7]dried and weighed before and after the experiments using a balance (H- Z- K 210 model) with an accuracy of 0.00001 g. The mass losses for samples were finally measured by considering their total surface area. Phase characterization of specimens before and after the immersion were carried out through [SM8]X-ray diffraction (XRD) [SM9]technique on a Phillips X‘Pert Pro diffractometer using monochromatic Cu-KÃŽ ± radiation. Morphology and chemical analysis of samples were also characterized using scanning electron microscopy[SM10] (SEM), SU8040model, equipped with an energy dispersive spectrometer [SM11](EDS). Electrochemical impedance spectroscopy[SM12] (EIS) measurements were done with a frequency ranging from 10 mHz[SM13] to 100 MHz. The results were analyzed by means of Zview2 software. Result and Discussion- The milling part Fig 1 shows the morphology of Al/Cu alloy and the Al/Cu-4wt.% B4C composite after 20 h[SM14] of mechanical milling. By increasing [SM15]milling time, the particle size decreases besides narrower size distributions.[SM16] The nearly equiaxed crystal morphology of particles suggests that, the 20 h[SM17] of milling time was sufficient to reach desired steady-state condition. Results in table 1 demonstrate[SM18] that by increasing the B4C contents, the average particle size decreases. Table 1 shows the influence of B4C content on the crystallite size and the lattice strain of aluminum matrix, according to Williamson–Hall method. As expected, the mechanical milling induced severe plastic deformation, leading to the formation of nano-crystalline metal matrix. The crystallite sizes varied with B4[SM19]C contents, showing the effect of hard particles on grain refining performance of metal matrix[SM20]. It is known that the milling stages introduce plastic deformation of ductile matrix, micro-welding, and the fracture of deformed particles in metal matrix [10, 11]. As compared to mechanical milling of soft powders, the presence of hard particles causes an increase in local deformation of matrix around reinforcement particles, which indeed would enhance the work-hardening rate of metal matrix. Additionally, fracture toughness of composite powders is lower than that of the matrix material [11]. On the other hand, an increase in the content of particles results in more frequent interactions between the dislocations and the hard particles [12], which accelerating the onset of mechanical-milling stage, and contributing to grain-refinement process [11].[SM21] Microstructural examination of as-cast composites revealed that the B4C particles were not distributed uniformly in the matrix and the regional clusters of particles existed. Since the wetting by molten matrix was poor, a uniform distribution of particles could not be observed in composites fabricated by stir casting. In addition, other factors like stirring speed, pouring condition, solidification rate, etc. [SM22]have also had a noticeable influence on particles distribution. In extruded samples, a more even distribution of B4[SM23]C can be observed. Fig. 2 shows the back-scattered electron SEM micrographs of extruded composites used in this study. A uniform distribution of ceramic reinforcements is evident in both composites. In addition, there are no traces of voids in the microstructure which in turn suggests that there was full-densification of composite upon extrusion.[SM24] Result and Discussion- The corrosion part Potentiodynamic Polarization Tests The Potentiodynamic Polarization behaviors of different samples in 3.5 wt% NaCl solutions after 1 hour of testing are given in Fig. 3. Their Ecorr, icorr and ipassive values (obtained from Tafel-type fit) are summarized in Table2[SM25]. Data shows that Al-cast has a lower corrosion rate than Al-milled. As the milled alloy has finer grains, it was expected to be less corrosion resistant because of having more grain boundaries, means higher susceptibility to electrochemical reactions and hence to corrosion. [SM26]It can also be seen that the characteristics of polarization curves for B4C composite samples are quite similar to base the alloy[SM27], indicating that the reactions are similar for both. According to table 2, adding 2wt.% B4C to the base material lowered the corrosion rate slightly, because the ceramic particles may to some extent hindered electrochemical dissolution physically. On the other hand, adding more B4C particle to the composite increases the corrosion rate. In any Al alloy-B4C composites, forming intermetallic compounds plays an important role in any chemical and electrochemical reactions that take place on composite surface in a corrosive environment. Fig.[SM28] 4 shows the X-ray diffraction pattern for Al 6wt.% B4C composite. It can be seen that other than Al matrix, there would be considerable amounts of Al3BC species which were produced when the Al reacted with B4C particles. As Al is more anodic with respect to intermetallic, having more of B4C in matrix dominates the effect of physical blocking of electrochemical reactions for ceramic particles in the solution and corrosion rate increases. Therefore [SM29]other than general corrosion of the matrix, there will be galvanic corrosion between the matrix and intermetallic resulting localized corrosion (pitting) on composite surface. In Al 6wt.% B4C sample, the corrosion rate decreased. This can be explained through passivation point of view as shown in polarization curves in which, the passive current density increases by increasing the B4C content. This may be caused by the formation of more porous and unstable passive layers produced by higher intermetallic particles and also leading to more susceptibility to localized corrosion.[SM30] Weight Loss Measurements Figure 5 represents the weight losses for different samples at different immersion times. Diagram demonstrates that the Al cast has the lowest weight loss, therefore [SM31]the lowest corrosion rate of all samples. B4C composites show higher corrosion rates than Al-milled suggesting that adding B4C to samples increases the corrosion rate.[SM32] As mentioned above, adding B4C to the alloy produces Al3BC intermetallic during corrosion.SEM micrographs of the Al 6wt.% B4C before and after the immersion for 28 days [SM33]are shown in Fig[SM34] 6. Al matrix and Al3BC intermetallic are pointed out in Fig. [SM35]6. EDX analysis results of the intermetallic phase from Figure 4-b is also demonstrated in Fig.[SM36] 7. It reveals that, considerable amounts of the compound exist in the matrix [SM37]which agrees with the XRD results discussed before. Finally, it is observed that the results from immersion and polarization tests are in agreement with each other. It is indicating that besides a general corrosion, there is a galvanic corrosion between the matrix and the particles leading to localized corrosion. Cyclic Polarization Studies: Characteristic potential values such as:[SM38] pitting potential (Epit), corrosion potential (Ecor), and re-passivation potential (Erp) were determined through cyclic polarization studies. As it is observed in Fig[SM39] 8, the nature of potentiodynamic polarization curves in the 3.5% NaCl solution reveals typical characteristics of the material undergoing spontaneous passivation. Reverse scan shows a hysteresis cycle, showing the characteristics of pitting. After reaching to a maximum level, the current begins to decay without any oscillation. Following a linear current-potential relationship is suggesting that an ohmic controlled process was taking place [12-15]. Additional electrochemical parameters given in the table [SM40]are: à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Epit=Epit-Ecorr, à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Erp=Epit-Erp. à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Epit is a measure of the width of passive region on polarization curve, indicating the susceptibility to pitting. à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Erp is used to assess the repassivation behaviour of propagating pits and hence, the ease with which locally active sites can be eliminated.[SM41] à °Ã‚ Ã¢â‚¬ ºÃ‚ ¥Eprotection represents Erp-Ecorr and indicates the protected region. Pits are formed in this region, repassivation and larger region means more resistance to pitting for composite. [SM42]According to table[SM43] 3, the largest protection region was belonged to Al cast. Milled sample showed a smaller region and because of having more grain boundaries on the surface, by creating smaller nucleation sites for pits, made the sample more prone to pitting. [SM44]Adding B4C to samples confines the region and lowered[SM45] the resistance to pitting corrosion. EIS Studies In order to study the corrosion behavior of B4C composites and the base alloy, EIS measurements were carried out for all specimens at their Ecorr in 3.5% NaCl solution. Figure 9 shows results in the form of nyquist[SM46] diagrams. There is a common characteristic for all curves, i.e. a capacitive semicircle in the high frequency ranges. High frequency capacity loop was mainly related to the characteristics of electrical double layer formed at the interface between the adsorption layer on [SM47]metal surface and the electrolyte [12]. The biggest semicircle was noticed for the Al cast sample, indicating that the alloy has the highest resistance to corrosion. Al-BM sample has an additional semicircle in low frequency range, which may be related to the charge transfer across the metal-electrolyte interface. Another noticeable point is that, inductive loop [SM48]is related to the salt layer formation on the surface. It may also demonstrate that, [SM49]adsorption of an anion like chloride which is presented in electrolyte,[SM50] caused the pitting corrosion. Al-BM also has[SM51] lower resistance to corrosion than Al-Cast. Corrosion resistance for Al 4%B4C sample was higher than the Al-BM. But for the 2% and 6% composites, there were less improvement observed [SM52][16, 17]. Conclusion Results from electrochemical measurements which were carried out on Cast and Milled alloys and the B4C composites[SM53] showed that,[SM54] adding B4C particles to milled alloys will not [SM55]change the corrosion resistance considerably. From corrosion resistance point of view, it would be fair to say that the best sample was[SM56] the Al 2%B4C.
