On the Unipolar Generator: An Experimental and Theoretical Study

When studying the phenomenon of the induced electromotive force, which originates from Faraday’s unipolar inductor, the contrast between Faraday’s view of the magnetic field dynamic lines and the theory of relativity is revealed. In order to remove this contradiction, this phenomenon was studied in depth, theoretically and experimentally, using an experimental setup similar to Faraday’s. Calculations of the induced electromotive force, based on relativity on the one hand and on Faraday’s view on the other were made with the help of measurements of the magnetic field components. Accurate magnetic field measurements are confirmed by analytical calculations. Precise-induced electromotive force measurements confirmed Faraday’s view and contradicted the theory of relativity.

Swedish Women’S Emotional Experience of the First Trimester in a New Pregnancy after One or More Miscarriages: A Qualitative Interview Study

Objectives: The aim of this study was to evaluate how Swedish women describe their emotional state of being during the eighth week through the eleventh week after they have become pregnant again after suffering a previous miscarriage. Method: A qualitative content analysis with an inductive approach has been used to analyze fourteen interviews that served as the data base for this study. The content analysis resulted in the development of five categories which evolved into one primary theme. Findings: The five categories identified were Worry and preoccupation;Distance;managing their feelings;Mourning what is lost;Guarded happiness and expectations. These categories were compiled into a main theme, “Worry consumes a lot of energy, but on the other side lies happiness”. This theme focused on whether the women could feel any happiness about being pregnant again despite their concerns with the previous miscarriage. Conclusions: The emotional states of the women when they get pregnant again are typically characterized by anxiety, worry and concerns about their current pregnancy. The women have a tendency to distance themselves emotionally from their pregnancy but also strive to find the joy of being pregnant again. During the new pregnancy they find themselves in need of support from their family and friends as well as in need of support from the healthcare system.

Outcome of non-variceal acute upper gastrointestinal bleeding in relation to the time of endoscopy and the experience of the endoscopist: A two-year survey

AIM: To prospectively assess the impact of time of endoscopy and endoscopist's experience on the outcome of non-variceal acute upper gastrointestinal (GI) bleeding patients in a large teaching hospital.METHODS: All patients admitted for non-variceal acute upper GI bleeding for over a 2-year period were potentially eligible for this study. They were managed by a team of seven endoscopists on 24-h call whose experience was categorized into two levels (high and low) according to the number of endoscopic hemostatic procedures undertaken before the study. Endoscopic treatment was standardized according to Forrest classification of lesions as well as the subsequent medical therapy. Time of endoscopy was subdivided into two time periods: routine (8 a.m.-5 p.m.) and on-call (5 p.m.-8 a.m.). For each category of experience and time periods rebleeding rate, transfusion requirement, need for surgery, length of hospital stay and mortality we compared. Multivariate analysis was used to discriminate the impact of different variables on the outcomes that were considered.RESULTS: Study population consisted of 272 patients (mean age 67.3 years) with endoscopic stigmata of hemorrhage. The patients were equally distributed among the endoscopists, whereas only 19% of procedures were done out of working hours. Rockall score and Forrest classification at admission did not differ between time periods and degree of experience.Univariate analysis showed that higher endoscopist's experience was associated with significant reduction in rebleeding rate (14% vs 37%), transfusion requirements (1.8±0.6 vs 3.0±1.7 units) as well as surgery (4% vs 10%), but not associated with the length of hospital stay nor mortality. By contrast, outcomes did not significantly differ between the two time periods of endoscopy.On multivariate analysis, endoscopist's experience was independently associated with rebleeding rate and transfusion requirements. Odds ratios for low experienced endoscopist were 4.47 for rebleeding and 6.90 for need of transfusion after the endoscopy.CONCLUSION: Endoscopist's experience is an important independent prognostic factor for non-variceal acute upper GI bleeding. Urgent endoscopy should be undertaken preferentially by a skilled endoscopist as less expert staff tends to underestimate some risk lesions with a negative influence on hemostasis.

Experience of the patient's success in facing post-stroke urinary incontinence: the patient's perspective

Objective:Post-stroke urinary incontinence(UI)is one of the sequelae of stroke.This situation affects all aspects of the patient’s life–physically,psychologically,socially,and spiritually.This study aimed to investigate the experience of patients’success in facing a post-stroke UI.Methods:A qualitative study using the Rapid Assessment Procedure(RAP)approach was used in this study.Informants were selected using purposive sampling.In-depth interviews with as many as 8 patients who had recovered from post-stroke UI and living in the greater area of Southeast Sulawesi(Indonesia)were conducted.In-depth interviews were also conducted with 8 caregivers and 2 nurses.Data were analyzed using a thematic analysis approach and interpretation of data was based on Humanbecoming theory and Self-care deficit theory of nursing.Results:Five successful things the patients experienced during post-stroke UI were identified.The five successes were as follows:they provided information to get to know and understand post-stroke UI,followed the procedures to overcome post-stroke UI,conducted self-control exercises and stayed motivated,performed daily activities independently according to ability,and made use of family suppor t and peers’attention.Conclusions:These findings indicated that persistence,belief,independence,and social support(family and peer)made patients to successfully face their post-stroke UI and improved their quality of life.These findings also became the basis for developing a poststroke UI management model based on Humanbecoming theory and Self-care deficit theory of nursing.

The Experiences of the Elderly and Caregivers in Respect of Caring for the Elderly in Windhoek and Rehoboth Namibia: An Exploratory and Descriptive Study

In many instances, care for the elderly, especially in long-term care institutions, is provided under minimal supervision by caregivers who are lay people. This can lead to poor quality care or neglect of the elderly. The research question was: “How competent are lay caregivers for the elderly in old age homes, who often lack the opportunity for training to improve their knowledge and skills, in delivering care to the elderly? The aims of the study were to explore and describe the experiences of both the caregivers and the elderly in respect of caring for the elderly in old age homes. The objectives of the study were to explore and describe the experiences of the caregivers and the elderly with respect to caring for the elderly and in respect of nursing care they received. A qualitative, explorative, descriptive, contextual and phenomenology design was used to perform this study. In the situational analysis, the experiences and needs of the caregivers were described. Themes in terms of interpersonal relationships that could be positive or negative regarding the elderly were identified. These included lack of regular in-service training sessions for caregivers. Likewise, sub-themes like communication, support and caring for elderly people were revealed. Inadequate knowledge of caregivers in caring procedures, a shortage of staff, equipment and absence of policies which should support and guide the work of caregivers impacts negatively on the care of the elderly. From the experiences of the elderly and caregivers, the competencies under scrutiny emerged and were measured qualitatively by the perceptions of the elderly, in respect of the caring they were exposed to.

MANAGEMENT OF MENEERE'S DISEASE—THE BEIJING TIANTAN HOSPITAL EXPERIENCE

Objective To report outcomes of nonsurgical and surgical management of Menire＇s disease at Beijing Tiantan Hospital. Methods Patients with Menire＇s disease were categorized into groups based on hearing and quality of life. Individualized management was provided, including life style modification, drug therapies, endolymphatic sac decompression and labyrin- thectomy. Treatment outcomes were evaluated during up to 24 months follow up. Results Eighty seven patients underwent life style modification and drug therapies. The vertigo control rate of Grade A and B was 76.9% and 83.8% respectively. Six patients received surgical management, including endolymphatic sac decompression （n = 5） and labyrinthecto- my （n = 1）. For these patients, the vertigo control rate of Grade A and B was 80% and 100%, respectively. Conclu- lsions Management of Meni6re＇s disease depends on several factors, i.e. severities of vertigo and hearing loss, quality of life, surgical contraindications and patient subjective desire. The treatment is drug therapies for the majority of patients, as well as life style modification. Surgical indications are rare and the least invasive procedures should be considered first. The results of surgery are generally satisfying.

China＇s Experience in Rural Poverty Reduction.Jobs from Industrialization and Urbanization to Increase Rural Household Income

This paper makes an appraisal of the successful experience of China, a country with the largest agricultural population in the world, in the reduction of rural poverty. We conclude that it is an indispensible strategy to give priority to the development of urban sectors to promote economic growth and reduce rural poverty, and that the development of low value-added agriculture yields few, if any, benefits in decreasing rural poverty. By first adopting urban-biased policies and promoting industrialization, China has created new sources of economic growth and urban employment opportunities to absorb the surplus rural workforce. Entering labor-intensive industrial sectors for higher incomes has thus become a critical avenue for the rural poor to benefit from economic growth and escape poverty.

Evaluation of Patients’ Experience Following Dental Implant Surgical Procedure

Background: Patient’s acceptability of dental implant prostheses may be influenced the fact that a surgical procedure is involved. Adequate relevant information by the dental professionals pre-surgery, is therefore, paramount to alleviating the fear of surgery and contribute positively to patient’s ability to cope with post-surgical experience. This study, therefore, aimed at evaluating the postsurgical experience of the dental implant patients. As against what was expected, and relate this with the information given pre surgery. Methodology: Post treatment self-completed questionnaires were administered to consented patients that had dental implants placed between July 2017 and December 2019. The surgical procedure followed the standard protocol and data related to post-surgical experience were collected one week after the surgery to obtain information on the level of pain/discomfort and amount of swelling experienced following surgery. The effect of the information on coping ability following surgery was also assessed. Data were analyzed using descriptive statistics (p value ≤ 0.05). Results: Twenty-seven patients received 44 implants to replace 48 teeth. The mean age of the patients was 45 ± 16.3 (SD) years. Teeth mostly replaced were the maxillary central incisors (39.6%). The majority of the patients 77.7% reported to experience less pain/discomfort than expected and 66.6% had less swelling than expected. While 29.6% felt they had excellent explanation of what to expect, 51.9% said they had good explanation. The post-surgical experience between males and females was not statistically significant (pain: p = 0.08, swelling: p = 0.64). However, the majority (8/12) that had good to excellent information preoperatively, had significantly less discomfort than expected. Conclusion: Positive, encouraging and satisfactory experience of patients following implant surgical procedure is related to adequate and correct information pre-surgery.

How Vaginal Infections Impact Women’s Everyday Life <br/>—Women’s Lived Experiences of Bacterial Vaginosis and Recurrent Vulvovaginal Candidiasis

Reoccurring symptoms and persistent problems that continue post treatment can be characteristic of the vaginal infections Bacterial Vaginosis (BV) and recurrent vulvovaginal candidiasis (RVVC). The purpose of this study was to describe women’s life experiences in managing the symptoms of bacterial vaginosis and Candida. Sixteen women were recruited and participated in an interview study when they contacted a Swedish gynecology clinic with vaginal complaints that ranged from and included abnormal discharge, irritation itching along with serious malodor. An interpretive phenomenological approach was used with an individual interview to get a more intimate understanding of the women experiencing these problems. The finding of this study shows that managing the recurrent symptoms of the infections remains to be a challenge for women as it has a clearly negative impact on the quality of their lives. Four themes developed: frustration and mood disorders, intimacy changes in the relationship, exposure, hope and relief. The women had high hopes of eliminating the symptoms within the six-month study period. The treatment program, with its well-developed guidelines and continuity of care within the context of the study greatly improved the quality of life of these women. Women had feelings of frustration and anxiety when nothing could cure their problem while they had also a great hope to get rid of the symptoms with a long striking treatment. Well-developed guidelines and continuity of care can help these women to have an improved quality of life.

What Is the Personal Experience of IBD Patients about Their Anti-TNF-Alpha Therapy?

AIM: To evaluate and compare the patients opinion on the two types of anti- TNF-α therapies in a Hungarian cohort of IBD patients. METHODS: This was a prospective, multicentre, questionnaire-based observational study carried out in three Hungarian tertiary centres. From April to September 2014, an anonymous questionnaire was distributed to patients diagnosed with ulcerative colitis (UC) or Crohn’s disease (CD), who have received infliximab (IFX) and/or adalimumab (ADA). The survey focused on the preferences of the two anti-TNF-α therapies on the basis of the efficacy, the administration routes and the side effects. RESULTS: 292 IBD patients, 216 CD, 75 UC and 1 indeterminate colitis patient completed the questionnaire. The mean duration of biological therapy was 1.7 (1 - 7) years. IFX treated patients noticed improvement of symptoms at 4 - 5 weeks while ADA treated patients noticed at 5 - 6 weeks. There was no difference between the patients’ satisfaction regarding the types of anti-TNF-α therapy if they received both. However, subcutaneous administration was preferred by ADA-treated patients previously receiving IFX (p = 0.007) compared to intravenous route and they did not intend to change the mode of therapy (p = 0.040). 90% of the patients, receiving only IFX or ADA were satisfied with their present therapy. The majority of patients (186/292, 63.7%) would not switch therapy. 63 of 291, 22% of the patients reported to have some concern with biological therapy—the majority (32/63, 50.8%) due to fear from side effects. CONCLUSION: Generally, patients preferred and would not change the present anti-TNF-α therapy, however, subcutaneous administration was preferred among those patients who had have experience with both.

Rethinking China's pension reform——The relevance of international experiences

Pension funds remain scarce no matter what institutional design is adopted. China has a host of unique issues facing its pension system,issues that must be confronted; for instance,the disappearance of its demographic dividends and legacy costs incurred due to institutional transition. Such features determine that China’s pension system is merely passable at the present time. In this article,Professor Cai Fang offers new and incisive perspectives on this issue,such as the potential stimulus for economic growth by ageing people’s desire to save money for old-age provisions.
