The League Of Nations During World War I - 2066 Words

The League of Nations was started after World War I to try to bring peace to this world after this horrid war we had just been in. It was proposed by Woodrow Wilson, to the allied forces to join in this league to use arbitration to make decisions on other nations matters so it can be solved before they try to start a war. This might sound all well but if you think about it, it is impossible to achieve world peace in general. The League of Nations was a great idea but in reality the US should not have joined the League of Nations.The League s goals included disarmament, preventing war through collective security, settling disputes between countries through negotiation and diplomacy, and improving global welfare. Despite these bold aims, the League proved incapable of preventing aggression by the fascist powers in late 1930s. The United Nations effectively replaced it after World War II and inherited a number of agencies and organizations founded by the League. The opposition to the Le ague of Nations comes from four sources: The extreme Socialists and radical revolutionists who look on all measures devised by government as at present constitution as â€Å"capitalistic† and as â€Å"bourgeois makeshifts†; from constitutives who considers any change as dangerous and revolutionary; from Republican party leaders who want to make political capital against Wilson a democrat, and from those who believe in an extreme nationalism and who feel that any international agreement will curbShow MoreRelatedWorld War I And Its Effects On America1703 Words   |  7 Pagesthe U.S. entered into World War, it had already been raging for some time.

Mechanical Test of LDPE and HDPE Processed by Extrusion, Injection Molding, Compression Molding and Sheet Extrusion Abstract LDPE and HDPE were processed by extrusion, injection molding, and sheet extrusion. Their mechanical properties such as tensile strength and percent elongation were measured by tensile test and analyzed statistically (Table 2). During the extrusion process, both polymers underwent die swelling. We will write a custom essay sample on Mechanical Test of Ldpe and Hdpe P or any similar topic only for you Order Now The water cooled polymer cords have a higher tensile strength but lower % elongation compared to the air cooled cords. HDPE has a much higher strength than LDPE due to its high crystallinity. LDPE and HDPE samples processed by injection molding and sheet extrusion show the same tendency in the extent of yield strength and elastic modulus. For sheet extrusion, the heat treated polymer sheet has a higher strength than the non-heat treated sheet because heating leads to an increase in both crystallinity and crystallite size. The specimen in rolling direction also has a higher strength than those in transverse direction due to the alignment of the polymer chains in rolling direction. UHMWPE (Ultra-high-molecular-weight polyethylene) saucer was processed by compression molding. The cross section of the saucer was examined by optical microscopy. Further, the melting temperature of PEO was determined to be 74. 0 °C ~ 78. 9 °C. Introduction A polymer is a chemical compound or mixture of compounds consisting of repeating structural units created through a process of polymerization. 1 The units composing polymers derive from molecules of low relative molecular mass. When all the repeating units along a chain are of the same type, the resulting polymer is called homopolymer. Chains composed of two or more different repeat units are termed copolymers. The physical characteristics of a polymer depend both on its molecular weight and shape, and the structure of the molecular chains. The chain structures include linear polymer, branched polymer, crosslinked polymer and network polymer. The polymer synthesized in this experiment, LDPE and HDPE, have different chain structures (i. e. LDPE is a branched polymer and HDPE is a linear polymer. ). The polymer chain structure has a significant influence on polymer crystallinity, which is defined as the packing of molecular chains to produce an ordered atomic array. The mechanical properties that investigated in this paper, such as tensile strength, elastic modulus and percent elongation, greatly depend on the crystallinity of the polymer sample. Polymers play an essential and ubiquitous role in everyday life from those of familiar synthetic plastics and other materials of day-to-day work and home life, to the natural biopolymers that are fundamental to biological structure and function. 1 Qu ite a variety of different techniques are employed in the forming of polymeric materials. Molding is the most common method for forming plastic polymers. The several molding techniques used include extrusion molding, compression molding, blow molding and injection molding. 3 During molding, crystal regions in polymer melts upon heating. The resulted polymer melts are non-Newtonian fluids, and their viscosity depends on the shear rate. Melt index (MI) could be used to indicate the viscosity of the fluid. It is defined as the mass of polymer flowing in ten minutes through a capillary of a specific diameter and length by a pressure applied. 4 Polymer melts are formed into a continuous charge of viscous fluid. The viscous fluid then solidifies into polymer product with specific shapes. During the solidification process, polymer melts recrystallizes and forms spherulite structure consisted of both amorphous region and lamellar. Experimental Procedure Crystallization of PEO Crystallization of PEO (Sigma-Aldrich Co. , St. Louis, MD) was observed by optical microscopy. Sample of PEO powder was placed on glass slide and heated up using hot stage. Both the melting and the solidification processes were observed under optical microscope under crossed polarizer. The melting range was determined to be 74. 0 °C ~ 78. 9 °C. Extrusion of LDPE and HDPE Both LDPE (MI = 0. 25, Equistar ) and HDPE (MI = 9, Equistar) pellets were processed into cords using single-screw extruder (Model TL3215B, Extruders ). The die temperature was 350  °C, Zone temperatures were all 425  °C and the screw speed was about 3. 6 rpm. Water cooling and air cooling were carried out for mechanical properties evaluation. Tensile tests were performed on both LDPE and HDPE cords in order to evaluate their mechanical properties. Compression Molding UHMWPE (Ticona) powder was used to produce UHMWPE saucer by using a compression molding apparatus (Model 3725, Carver). The starting temperature was 245 F, and the molding temperature was 310 F. The cross section of the saucer was examined by optical microscopy. Injection Molding Both LDPE (MI = 9, Equistar) and HDPE (MI = 7, Equistar) pellets were processed into dog bone specimens by injection molding. The barrel, nozzle and mold temperatures used are listed below. Tensile tests were performed on both LDPE and HDPE specimens in order to evaluate their mechanical properties. Table 1. Barrel, Nozzle and Mold temperatures for injection molding. | LDPE| HDPE| Barrel Temperature | 390 °F| 400 °F| Nozzle Temperature| 395 °F| 405 °F| Mold Temperature| 275 °F| 275 °F| Sheet Extrusion Both LDPE (MI = 0. 25, Equistar) and HDPE (MI = 9, Equistar) pellets were processed into polymer sheets using sheet extruder (Model KLB125, Extruders). The die temperature was 375  °C. Zone temperatures were all 420  °C. Adapter temperature was also 420 °C. The screw speed was about 20 rpm and the roller speed was set up to 2. 0 rpm. Heat treatment using glass furnace was performed on both polymers. Tensile tests were carried out in order to evaluate the mechanical properties of both LDPE and HDPE. Result and Discussion Crystallization of PEO The melting temperature of PEO was determined to be 74. 0 °C ~ 78. 9 °C, where the literature melting temperature of PEO is 65 °C. The polymer melting behavior is a function of the rate of heating5. That the measured melting temperature is higher than the literature value results from the relative high heat rate (20 °C/ min). Besides, the melting temperature for polymer is a range instead of a single point. The melting temperature depends on the molecular weight of the polymer chain, the thickness of the chain-folded lamellae, the heating rate and the impurity content. You read "Mechanical Test of Ldpe and Hdpe P" in category "Papers" Since the PEO samples used contain polymer chains with different size, and they were heat at an inconstant rate, the melting must take place over a range of temperatures. | | | | Figure 1.

The spherulite consisted of chain-folded crystallites (lamellae) and amorphous region start to grow from the nucleation site at 56. 7 °C. Individual lamellae are separated by amorphous materials. As shown in Fig. 2 (c), the spherulite keeps growing and getting larger as the recrystallization process continues. When the crystallization of a spherulite structure nears completion, the extremities of adjacent spherulites begin to impinge on one another, forming planar boundaries (Fig. 2 (d)). At 56. 0 °C, the crystallization process of PEO sample reached completion. Compression Molding A A | B B | Figure 3. Micrographs of middle cut (B) and outer cut (A) of UHMWPE saucer at 20X. The mold is closed with a top force. Pressure is applied to force the material into contact with all mold areas, and heat and pressure are maintained until the molding material has cured. During that process, particles diffuse together and become one piece. As shown in Fig. 3, the outer cut of the UHMWPE saucer has lower porosity, and the middle section of the saucer has a much higher porosity. The outer region of the saucer was cooled much faster than the middle section of the saucer. Slowing cooling rate in the middle section led to the high porosity. Liquidus polymer shrinks as it solidify into solid leaving a large amount of pores in the middle section. Extrusion and Sheet Extrusion Die swell happened during extrusion as shown in Fig. 4. A flow stream has a constant rate before entering the die. It also occupies a spherical conformation and maximizes the entropy. 6 As it goes through the die, polymer loses its spherical shape and becomes less entangled. Therefore, the entropy is lowered. When polymer melt comes out of the nozzle, the remaining physical entanglements cause the polymer melt to relax (i. e. egain a portion of its former shape) and restore the entropy. It appears like the polymer is swelling at the nozzle. Figure 4. Die swelling happened when polymer melt came out of the nozzle. Air cooled LDPE took 3 runs before fracture, and the water cooled LDPE took 2 runs before fracture. As shown in Fig. 5, both water cooled and air cooled LDPE cords have sim ilar elastic modulus and yield strength. However, the air cooled cord has a higher tensile strength but lower percent elongation. Since the degree of crystallinity depends on cooling rate during solidification, the higher the cooling rate , the higher the degree of crystallinity. Increasing in crystallinity increases the hardness but lower the ductility of the polymer cords. Thus, water cooled LDPE cord has higher tensile strength but lower % elongation compared to the air cooled one. Figure 5. Extrusion sample stress vs. strain plot. Red curve represents water cooled LDPE cord, and blue curve represents air cooled LDPE cord. Figure 6. Sheet extrusion sample Stress vs. Strain plot. Blue curve represents heat treated LDPE specimen in rolling direction. Purple curve represents non-heat treated LDPE specimen in rolling direction. Red curve represents non-heat treated LDPE specimen in transverse direction. Green curve represents heat treated LDPE specimen in transverse direction. Figure 7. Sheet extrusion sample Stress vs. Strain plot. Blue curve represents non-heat treated HDPE specimen in rolling direction. Purple curve represents heat treated HDPE specimen in rolling direction. Red curve represents non-heat treated HDPE specimen in transverse direction. Green curve represents heat treated HDPE specimen in transverse direction. Tensile test result of sheet extruded LDPE and HDPE specimens are shown in Fig. 6 and Fig. 7 above. HDPE specimens have higher yield strength, elastic modulus and % elongation. HDPE has a linear chain structure. It was highly packed. Therefore, it has a larger density and higher degree of crystallinity than LDPE. Molecular chains are closely packed in an ordered arrangement in crystalline region. The alignment of the packed chains in crystalline region makes the intermolecular secondary bonding much stronger than it is in amorphous region. Thus, HDPE with higher crystallinity has a much higher strength than LDPE. The heat treated specimen has higher yield strength and tensile strength than non-heat treated specimens. It is also due to the increasing in the percent crystallinity, which makes the polymer harder but less ductile. Further, polymer specimen in rolling direction has higher yield strength and elastic modulus, but lower percent elongation compared to samples in transverse direction. It is because during drawing the molecular chains slip past on another and become highly oriented. This alignment once again enhances the tensile modulus in the direction of drawing (RD), while reduces the tensile strength in the direction (TD) perpendicular to the rolling direction.

HDPE specimen has a yield strength of 22. 61 ±3. 54 MPa, an elastic modulus of 0. 53 ±0. 27 GPa, and a percent elongation of ( 251. 50 ±301. 35 )% within 95% confidence interval. LDPE specimen has a yield strength of 5. 85 ±0. 94MPa, an elastic modulus of 0. 049 ±0. 012GPa, and a percent elongation of (142. 75 ±15. 72)% within 95% confidence interval. T-test was carried out to compare the difference between the literature value and the experimental value for both yield strength and elastic modulus. The result shows that the experimental yield strength and elastic modulus of both LDPE and HDPE differ from their literature values significantly. Both LDPE and HDPE have a wide range of % elongation, therefore, the difference between experimental %EL and literature %EL was not examined. In addition, there are significant difference between the yield strength of LDPE and the yield strength of HDPE (T-test shown in Appendix) that HDPE has a much higher strength than LDPE. It is because HDPE has a highly packed linear chain structure, a larger density and a higher degree of crystallinity than LDPE. Conclusion Total three types of polymer, UHMWPE, LDPE and HDPE, were processed via four molding techniques. UHMWPE saucer was produced by compression molding. The cooling rate of the polymer melts has a great influence on the porosity of the polymer. Die swelling happened during extrusion as a result of the relaxation of polymer melts. The melting temperature of PEO was determined to be 74. 0 °C ~ 78. 9 °C. The inconstant heat rate and the fact that PEO is composed of molecules having a variety of molecular weight make the temperature range well above the literature melting point. The air cooled extruded cord has a higher tensile strength but lower percent elongation due to higher crystallinity. HDPE is harder but more ductile than LDPE. It also results from its highly pack linear structure and higher degree of crystallinity. T-test was performed on injection molded samples that HDPE specimen has a yield strength of 22. 61 ±3. 54 MPa, an elastic modulus of 0. 53 ±0. 27 GPa, and a percent elongation of (251. 50 ±301. 35 )% while LDPE specimen has much a lower yield strength of 5. 85 ±0. 94MPa, an elastic modulus of 0. 049 ±0. 012GPa, and a percent elongation of (142. 75 ±15. 72)% within 95% confidence interval.

The South-Coast Health system owns three hospitals, twenty seven Clinical offices, a Cancer Institute, Intensive care- facilities (ICU),Emergency services, Medical labs and Radiology Departments, with the Visiting Nurses service. South coast is also a fast growing Health care service System in New England too. This Health system has employed approximately seven thousand workers in its Departments, including three hundred physicians and has two hundred visiting nurses, with this it provides a wide range of medical services at each campus for Advance Medical facilities. South coasts mission is to provide Advanced Care, Close to Home for the patients it treats. With this South-Coast Health System also has a goal to grow their organization in fast manner with providing exceptional Health care by providing distributed setting for their patients, through- outpatient centres by the help of newly acquired Physician practices? The organization also desires to recruit and retain best Medical staff services for their Hospitals. For obtaining this goal, the organization plans to provide uniform access to the patient health records to the Visiting Doctors and Nurses regardless any device they are using for example Laptop or smart mobiles, Tablets etc. With this South-Coast Health care also demands the security of their patients information. The South-Coast Health System along with above discussed clinical requirements also expects reduced cost in the IT Venture for their organization. Solution through Virtualization With respect to Citrix- Major Challenge- To provide best Patient Health care facilities and facilitating the privacy of patient information in the distributed Mobile Environment. The Solution- Developing an Integrated Electronic Medical Record system and constructing the simple, securely developed mobile workstation that is required by the Hospital Staff. 1. Converting Patient Record into the EMR- To provide the solution of the above discussed issues, firstly the conversion of whole patient data into the Integrated Electronic Medical Record (EMR) through Citrix solution-Epic was developed. Now the Doctor as well the Nurses can access patient data either from their office or in Hospital using same user-id to access data from the Epic. With this Hospital Medical staff is now able to get the detail of the patient whether the patient is in Hospital or discharged to the visiting nurses services. 2. Facilitating Access of data with the help of any of Mobile Device of choice- Secondly in order to provide the access of data through any of the Mobile Devices of choice, the rough idea of no of Laptops, Mobiles , PCS in Network was made, on observation approximately six thousand Personal Computers and Eight hundred Laptops in the network found. For providing the solution for this area the organization took help of Citrix solution by selecting Citrix -Remap and Citrix Xen-Desktop as the foundation to deliver its integrated EMR system along with Fifty other clinical and nonclinical applications. Now the environment runs on the Cisco Unified Computing System platform and utilises the Citrix NetScaler as a front end service. The organization also uses Citrix XenServer for all of the Citrix environments along with Epic now. For providing the Advance Mobility features, the Southcoast chosed Citrix XenMobile as its enterprise mobility management solution. The XenMobile helps to handle th e mobile device management as part of its application, and it also provides the flexibility to support the bring-your-own-device policies. Now IT System of South Coast are capable of locking devices, wiping data, upgrading and managing devices, and be proactive in case of a security management-all while creating an fine medical experience for their users. 3. Making the fast organizational growth and maintaining the operational overhead at less than percent of annual budget- With the advance features provided by the Citrix , the organization now has progressed and achieving its targets. 4. Developing methods to protect sensitive patient information- With the help of the Citrix solutions, South coast organization now keeps patient data safe and ensures sensitive information remains to be private. The new developed infrastructure protects against data leakage and controls the inference of new mobile devices, even when the medical staff bring their own devices in the premises. Views by IT Department of South Coast Hospital- One best reason to select Citrix for our end-to-end platform is that it facilitates the Medical staff with a connected without interruption work for the hospital. Christian Boucher Manager of Directory Services for Desktop and Mobile Engineering Southcoast Health System Citrix provides the Facility to Medical Staff to work in from the office or the hospital, they use the same user ID to access Epic Mark Lacombe Director of information technology Southcoast Health System There are several chances when the Doctors and nurses has to face problems when the system is in downtime, it also puts impact on the patient care. With the help of citrix platform, we are capable to refresh, upgrade and advance the environment without affecting operating of the services of Hospital, which operates 24/7, 365 days a year.
