The present study focused on investigating the growth mechanism of -oriented grains from low strain to high strain. The orientation characterizations of Ti-5Al-5Mo-5V-1Cr-1Fe alloy under different strain rates and compression temperatures were studied by EBSD technique. The dynamic recrystallization grains were selected by the GOS method to reveal the effect of dynamic recovery and recrystallization on texture evolution. 2. Materials and Experimental Procedures The Ti-5Al-5Mo-5V-1Cr-1Fe alloy used in this study was obtained from a hot forged bar with a diameter of 350 mm. The composition of the alloy was 5.23 Al, 4.85 Mo, 4.93 V, 0.92 Cr, 1.17 Fe, and balance Ti. The β-α+β transus temperature of Ti-5Al-5Mo-5V-1Cr-1Fe was approximately 1143 …show more content…
1b. The initial grains of the alloy are equiaxed with a size of approximately 80–100 μm. Figure 1. {100} Pole figure (a) of the as-received Ti-5Al-5Mo-5V-1Cr-1Fe alloy bar and original microstructure (b) after solution treatment. 3.2. Texture Evolution during Hot Compression Deformation parameters including the strain and strain rate exert an important influence on the texture components during hot compression around β transus temperature. Figure 2 shows the EBSD test results of the samples compressed at different strain rates of 1/s, 0.1/s, and 0.01/s by reductions of 20%, 40%, 60%, and 80% at 1153K. Figure 3 shows the fractions of two main fiber textures including and fiber textures. The two main texture components of the sample with 1/s strain rate nearly retained the same volume fraction after 40% compression. The intensity of fiber texture increased with decreasing strain rate. Especially, the sample compressed with 80% reduction under 0.01/s strain rate only showed texture. It can be deduced that at the initial stage of compression, the strain rate has a weak effect on the texture evolution. With increasing deformation, low strain rate may be benefit for the development of texture and texture is gradually weakened or even vanished. Figure 2. Orientation maps by EBSD under different parameters, a1–a4 are under 1/s with 20%, 40%, 60%, and 80% reduction, b1–b4 are under 0.1/s with 20%,
Christianity assumes that our human nature is fundamentally and thoroughly flawed by sin, to the point where a divine miracle of grace is needed to allow us to trust Christ as Savior. Most people in Western cultures, however, do not consider themselves to be sinners and therefore feel no need for a Savior. Comment on this in the light of the detailed accounting rules and regulations intended to prevent investors from being defrauded, and the multi-billion dollar worldwide auditing profession that is intended to add credibility to financial statements.
The Quality and Safety Education for Nurses (QSEN) is an institute dedicated to the quality and safety for patients by helping nurses gain the knowledge, skills, and attitudes (KSAs) to provide patient care (QSEN Institute, 2017). Specimen labeling errors fall under the QSEN competency of safety. The purpose of this paper is to present the current problem with specimen processing and compose a second solution to this problem. The organizations that support my project, the National Safety Patient Foundation (NPSF) and the Institute for Healthcare Improvement (IHI), will be discussed as well. Finally, an overall evaluation of the clinical practice project and preceptor experience will be presented.
The EDS elemental mapping of the sample are shown in Figure 3-14. It can be seen that a layer of Al starts to be shaped between two layers of Ti. As it was shown earlier in Figure 2-10, the first transition time is around 1second after machining. It can be
The state having to repay Medicaid may mean a cut in billable services for Nebraska DD providers. In a staff meeting at Nebraska-DHHS, DD Director Courtney Miller, “the proposed plan is to allow 35 billable hours of Day Habilitation per week instead of 40. This should save money and pay what is owed to Medicaid-CMS” (Miller, personal communication July, 2nd, 2017). However on problematic billing issue with Medicaid, the Omaha World Herald article mentions, “it’s more instability to a system that’s struggling to begin with,” said State Sen. Colby Coash of Lincoln, chairman of the Legislature’s developmental disabilities oversight committee. We really can’t afford to lose any providers” (Omaha World Herald, 2014).
Winds of disaster, waves of multitude, preparations galore, the wait is on to determine the outcome of a hurricane. Being one of the most devastating and feared natural disasters, hurricanes are a brutal and unpredictable force. Never knowing what could happen or what they will do, forewarning and preparation for hurricanes are highly recommended. A hurricane is a form of a tropical cyclone or severe tropical storm that occurs in the eastern Pacific Ocean, Caribbean Sea, Southern Atlantic Ocean and Gulf of Mexico (conserve-energy-future.com). The cause of a hurricane is a force of nature, but the effects that follow are to land,
There absolutely needs to be some kind of solution where there is a restriction put in place when it comes to the internet exposing personal information along with online social media with juries conducting trials. Social media and the internet itself has the largest influence on why we have so many hung juries. Nowhere has the rise of the Internet posed so complex a challenge to public policy as it has to the tradition of public access to judicial processes and records. Traditionally, most court files are available to anyone willing to go to the courthouse and look at them. Many have argued that open courts are a fundamental aspect of maintaining a working democracy. Open court records produce responsibility and public confidence in the operation of the judiciary, the operation of other government agencies and the uniform enforcement of laws. Only through public access, for instance, can citizens be assured courts are fulfilling their role of protecting the rule of law. Practical barriers to information use and dissemination imposed by traditional
Preventative efforts to reduce stress ulcer development include pharmacological agents such as proton pump inhibitors (PPIs) and histamine 2 receptor antagonists (H2RA) (Kersh et al, 2017). The continued use of SUP, such as PPIs, may increase the risk of ventilator-associated pneumonia and Clostridium difficile infections (CDIs) by suppressing gastric acid of bacteriostatic effect (Ro et al, 2016). Because of widespread prophylactic use of pharmacologic agents and the development of hospital-acquired infections (HAIs), healthcare costs have increased by $14,000 per patient (Barletta & Sclar, 2013). Although some evidence suggested that SUP should be implemented for those at increased risk for stress ulcers, it is unclear to whether or not

Education is one of the most important aspects of a nurse’s role with patients. This is especially true of the community health nurse. The area of primary prevention and health promotion is gaining special popularity as educational material for nurses as healthcare is shifting towards heavily focusing on prevention of diseases and preservation of health. This teaching experience featured information about vaccines that would be pertinent to teach to parents of all ages and nationalities utilizing a childcare center in Tempe, AZ.
“Lets go smoke some weed man” now when that question gets asked to you, you might have to say no. Why is that? You think of the consequences that could come to you if you do it and get caught. As of now pot is illegal and most parents don’t accept there kid smoking weed. So in this paper I will tell you why pot should be legal. I will also give some things that have been said negative and I will disprove them. I will also discuss about hemp, what marijuana is and where it comes from. Also as you are reading this I will use two other names for marijuana these are pot and weed.
Since 2015, the American Association Colleges of Nursing (AACN) has promoted doctorate level graduate training for advance practice nurses. [1] The AACN’s Position Statement on the Practice Doctorate in Nursing calls for advanced practice registered nurses (APRNs) to pursue training that enables them to assume organizational roles encompassing increased clinical responsibilities. As the nation’s complex health care environment evolves, APRNs are practicing to the full extent of their capabilities.
