Multipoint observations of compressional Pc5 pulsations in the dayside magnetosphere and corresponding particle signatures
Get PDFWe use Van Allen Probes (Radiation Belt Storm Probes A and B, henceforth RBSP-A and RBSP-B) and GOES-13 and GOES-15 (henceforth G-13 and G-15) multipoint magnetic field, electric field, plasma, and energetic particle observations to study the spatial, temporal, and spectral characteristics of compressional Pc5 pulsations observed during the recovery phase of a strong geomagnetic storm on 1 January 2016. From ∼ 19:00 to 23:02 UT, successive magnetospheric compressions enhanced the peak-to-peak amplitudes of Pc5 waves with 4.5\u276.0 mHz frequencies from 0\u27 2 to 10\u2715 nT at both RBSP-A and RBSP-B, particularly in the prenoon magnetosphere. Poloidal Pc4 pulsations with frequencies of ∼ 22\u2729 mHz were present in the radial Bx component. The frequencies of these Pc4 pulsations diminished with increasing radial distance, as expected for resonant Alfv n waves standing along field lines. The GOES spacecraft observed Pc5 pulsations with similar frequencies to those seen by the RBSP but Pc4 pulsations with lower frequencies. Both RBSP-A and RBSP-B observed frequency doubling in the compressional component of the magnetic field during the Pc5 waves, indicating a meridional sloshing of the equatorial node over a combined range in ZSM from 0.25 to-0:08 Re, suggesting that the amplitude of this meridional oscillation was ∼ 0.16 Re about an equatorial node whose mean position was near ZSM D∼ 0:08 Re. RBSP-A and RBSP-B HOPE (Helium Oxygen Proton Electron) and MagEIS (Magnetic Electron Ion Spectrometer) observations provide the first evidence for a corresponding frequency doubling in the plasma density and the flux of energetic electrons, respectively. Energetic electron fluxes oscillated out of phase with the magnetic field strength with no phase shift at any energy. In the absence of any significant solar wind trigger or phase shift with energy, we interpret the compressional Pc5 pulsations in terms of the mirror-mode instability
Degeneration of Settler Colonialism in Contemporary Cinematic Depictions of the U.S. West: Introduction
Get PDFThe settler’s situation is underpinned by the fear of having been caught in a process of endless transition, hence the determination to define the parameters of collective sovereignty and to establish a satisfactory existential basis. The sense of uncertainty that underlies the settler’s situation accounts for the necessity of developing power structures that sustain the settler collective’s striving to complete its design, and this triggers a range of conflicts. Repeatedly addressing the eponymous region’s legacy of settler colonialism, film depictions of the American West re-inscribe oppression of racial minorities, sexual abuse, and class exploitation in order to validate the foundational settler-nation myth that consolidates hegemonic forms of racial, economic, cultural, and political power
Fostering Humanization: Providing Care in the Margins
Get PDFThis doctorate of nursing practice project aimed to restore or improve the physical, emotional, and spiritual health in the marginalized population in Rochester, Minnesota to promote human dignity and foster humanization through the opening of a nursing-led drop-in center. Guided by Jean Watsons Theory of Human Caring, the Rochester Health Commons was opened and provided personal hygiene supplies, foot soaks, foot care, community resources, and most importantly offered a place for people to feel welcomed and cared for. Utilizing the concepts of transpersonal caring, authentic listening, mutuality, and radical hospitality, transcultural nursing students serving at the Rochester Health Commons reduced barriers to care and improved health and healing for all that entered the door. Guest counts were tracked each week and an increase in the number of returning guests was thought to be favorable. Comments made by guests were also tracked as means of evaluating the project and specific themes emerged that confirmed guests feel welcomed and cared for. The nurses gained wisdom and knowledge from the guests which helped decrease stigma and judgement advancing nursing practice
Care During Pregnancy While Hemodialysis Dependent
No full textPregnancy while dependent on hemodialysis is uncommon. Historically pregnancy with end-stage renal failure has been considered very high risk with many pregnancies ending in miscarriage. With improvements in the dialysis process along with providers\u27 increased knowledge about pregnancy and renal dysfunction, the number of successful pregnancies while hemodialysis dependent is increasing. It is essential to provide proper medical and psychological care to the mother during pregnancy while hemodialysis dependent to improve outcomes for successful delivery of the baby. The purpose of this project is to create and implement a practice guideline to prevent the disparity in the treatment of pregnant women suffering from end-stage renal disease on hemodialysis at a large mid-western institution. This is accomplished with application of Newman’s Theory of Health as Expanding Consciousness with a multi-disciplinary approach supported by literature. The use of a conceptual model further illustrates the best care for pregnant women on hemodialysis at a large mid-western care facility
Restorative Yoga Practice in Arthritis
No full textArthritis is a condition that affects the joints and causes inflammation throughout the body. Most individuals with arthritis experience joint pain and stiffness that can impede mobility. Physical activity is a proven effective means in relieving pain and reducing the disability. A scholarly project was designed to evaluate the effects of yoga with the goal of improving individuals’ physical function, pain reduction and improving their perception of quality of life and overall well-being. A pilot study was conducted with an introductory program of Restorative Yoga with 5 individuals recruited from a southwest regional arthritis clinic diagnosed with osteoarthritis or rheumatoid arthritis. The outcome measured by Wilcoxon Signed Rank test indicated no change. Individual comparisons showed 4 of 5 individuals had improved flexibility, less pain and overall sense of well-being. One of 5 did not report any change in flexibility, pain or well-being but anecdotally commented that she did. A limitation for the study was that the sample size was too small to accurately measure a benefit. Individual comparisons indicated clinical significance. Watson’s Human Caring Theory and her Caritas processes that provided integrity and strength to the project were authentic presence, heart centered practice, and mutuality/universality. Expansion of the pilot study in private practice is an important undertaking to prove statistical significance in the benefit of Restorative Yoga practice by individuals with a diagnosis of arthritis
Increasing Autism Awareness in the Somali Community
Get PDFAutism spectrum disorder has become more prevalent in recent years, especially in the Somali community in Minneapolis. Early detection, diagnosis and interventions are essential for children with this disorder. A recent study on the prevalence of autism spectrum disorder in Minneapolis, Minnesota reported that Somali children not only have the highest prevalence of this disorder among all races and ethnicity but also receive late diagnosis and interventions. A comprehensive literature review identified lack of awareness, cultural stigma, and difficulty to access services as barriers for early diagnosis and interventions for Somali children. The literature also supported the importance of early diagnosis and interventions for children with autism and the effects autism spectrum disorder diagnosis can have on the family. The purpose of this project is to increase awareness of autism in the Somali community which can lead to early diagnosis and intervention. In addition, this project aims to support Somali parents of children with autism through education, advocacy, and support. The theoretical framework for this project is Leininger’s Culture Care Theory because of its emphasis on culture and care. This project utilized participation-observation as methodology. Five Somali parents of children with autism living in Minneapolis, Minnesota participated in this project. The project outcomes identified unfamiliarity with autism, fear of cultural stigma, barriers to access services, acceptance, support and strong faith as themes. Finally, this project discusses the significance and implications to nursing and how the doctor in nursing practice-family nurse practitioner can educate, support and advocate for this population
Does the Gut Microbiome Play A Role in the Development of Type 2 Diabetes Mellitus?
No full textRecent evidence suggests that the gut microbiome may favor the occurrence of metabolic diseases such as diabetes mellitus. Multiple studies over the last decade have demonstrated that the microbial community that colonizes the human gut may also play a role. The human gut flora is a collection of bacteria, archaea and eukarya that colonize the GI tract and has evolved over thousands of years to form a relationship with its human host. gut microbiota is considered healthy until changes and imbalances cause altered health states. The purpose of this paper is to research if the gut microbiome has a role in the development of type 2 diabetes mellitus (T2DM). This literature review concluded after analyzing the studies mentioned in this paper, the gut microbiome most likely does play a role in the development of T2DM. Significant microbial dysbiosis occurs in T2DM patients compared to non-diabetics. Gut biomarkers can be used to identify pre-diabetics or diabetic patients in a clinical setting. Manipulation of the gut via probiotics can possibly prevent and even treat T2DM. Butyrate, GLP-1, and SCFA producing bacteria seem to be altered in the gut of T2DM patients which may be modifying insulin secretion and blood glucose levels. However, more research and larger clinical trials are needed to be certain. Using terms related to gut microbiome and diabetes, this paper relied heavily on the PubMed search engine for relevant, peer-reviewed, research articles. Most of the articles used are no more than 10 years old
The Glass is Always Half Empty: anm Analysis of the Negative Worldviews for Those With Atxiety and Depression
Get PDFSince it was first proposed by Leon Festinger in the 1950s, cognitive dissonance theory has been the subject of many research papers. Explorations have expanded the theory to provide further insight into the conditions required for this phenomenon to occur, how it can be observed, and how it affects judgment. Cognitive dissonance has also proved useful in creating new ways to treat various mood disorders, such as depression and anxiety. The success of this type of therapy implies that there may be a stronger connection between these two topics that are often discussed apart from each other. This paper will outline the development of cognitive dissonance theory, its current applications in terms of psychotherapy, and the potential future studies that could further examine how cognitive dissonance relates to depression and anxiety
Misuse of Prescription Stimulants and Their Effect on Cognition
Get PDFPrescription stimulants like Adderall and Ritalin are increasingly being diverted and misused by college students who fail to recognize the potential health risks in an effort to improve academic performance. The main aim of this literature review is to address the prevalence of their misuse, the effects they have on cognition, and adverse side effects that are typically associated with their use. Despite being frequently referred to as cognitive enhancers or smart pills, results from studies on these medications remain mixed/unclear as to whether cognitive domains such as memory, executive function, and processing speed are actually enhanced. However, not surprisingly, it has been made clear that both individuals with ADHD and individuals without ADHD see some benefit with regard to the cognitive domain of attention when using prescription stimulants. On top of the need for further studies, there is much ethical debate to be had regarding the use of these medications and their presence in academia and society
Does Hyperthermic Intaperitoneal Chemotherapy Treatment Increase Life Expectancy in Ovarian Cancer Patients?
No full textBackground - Ovarian Cancer (OC) is the 5th most common type of cancer and the deadliest gynecologic cancer. Hyperthermic intraperitoneal chemotherapy (HIPEC), is a non-traditional chemotherapy mostly used for intraperitoneal malignant disease, offers a more efficient way of eradicating the disease. The aim of this research is to compare current management of ovarian cancer with HIPEC treatment. Because HIPEC is delivered through a single treatment during cytoreductive surgery (CRS), the side effects should be less invasive to the patient.
Methods - Data was retrieved from clinical trials, meta-analysis, review articles, and were studied and compared. Most of the research analyzed was conducted in Europe. Notable studies include a review of HIPEC timeline, advantages of neoadjuvant therapy, chemotherapy agents, side effect profile, and a quality of Life (QOL).
Results - Although further research is required, the current body of published journals support the efficacy of HIPEC in ovarian cancer. Worldwide, during the last 40 years, research supports that CS and HIPEC improves survival rates of intraperitoneal cancer including OC.
Conclusions - HIPEC has been shown to prolong overall survival rates. It is important to note that the optimal time to conduct HIPEC requires further evaluation. Common chemotherapy drugs such as Paclitaxel seem to be the most common drugs used for the treatment. However there is not solid agreement on adjuvant and neoadjuvant considerations. At this time, recurrent malignancy and secondary cytoreduction surgery (SRC) should be further studied and compared for more consistent results
