Abrasion Resistance of Thermally Treated Beech Wood

Research Article of International Research Journal of Materials Sciences and Applications Abrasion Resistance of Thermally Treated Beech Wood Rastislav Lagaňa Department of Wood Science, Faculty of Wood Sciences and Technology, Technical University in Zvolen, Slovakia The study focused on the abrasion resistance of beech wood thermally treated at high temperatures. A standard test for determining abradability, according to ISO 4649, was used. We studied factors such as the anatomical direction, temperature of treatment, and duration of treatment, as well as their effects on abrasion resistance performance. Four temperature levels (20 °C, 160 °C, 180 °C, and 200 °C) and three durations of treatment (1 h, 3 h, and 5 h) were used. Results showed that the anatomical direction was not a significant factor, but there was a strong influence of temperature and duration of treatment, respectively, on abrasion resistance. Due to a strong correlation between moisture content and abrasion resistance, the equilibrium moisture content of thermally treated wood could be used for the prediction of abrasion resistance Keywords: Abradability, thermal treatment, beech, abrasion resistance ...

Human Rights Violation of the Elderly People in Bangladesh: Do They Enjoy Basic Needs?

Research Article of International Journal of Aging Research Human Rights Violation of the Elderly People in Bangladesh: Do They Enjoy Basic Needs? Md. Zahid Hossain1,  A.K.M. Mahmudul Haque2*, S. M. Akram Ullah3 1MSS, Department of Political Science, University of Rajshahi, Rajshahi-6205, Bangladesh. 2Associate Professor, Department of Political Science, University of Rajshahi, Rajshahi-6205, Bangladesh. 3Professor, Department of Political Science, University of Rajshahi, Rajshahi-6205, Bangladesh. Basic needs are the fundamental human rights recognized by national and international law. This study is an attempt to reveal the picture of human rights violations of the elderly people in Bangladesh focusing particularly on the deprivation of the basic needs of the aged people. In this study, data have been collected from both primary and secondary sources. It reviews the right to basic needs, such as adequate food, clothes, shelter, healthcare, and education. As a human being, everybody deserves these basic needs as fundamental human rights and it is a fundamental responsibility of the state to secure these rights according to the constitution of Bangladesh, Article 15(a). But the study found that these basic rights are not implemented properly in the case of elderly people of the study area. Lacks of moral education and humanity have been identified as mainly responsible hindrances in this sphere. Corruption and poverty are also strong impediments in this regard. The paper proposes some workable suggestions. The government, responsible institutions, and concerned families should come forward to ensure proper education, to ensure proper and sound socialization with native culture, and to raise far-reaching consciousness regarding the welfare of elderly people.

Numerical Simulation of Hole Distribution Blasting with Different Distribution Forms

Research Article of Scientific Research and Reviews Numerical Simulation of Hole Distribution Blasting with Different Distribution Forms Zhang Xiaoxiao Guizhou University, Mining Institute, Guiyang, Guizhou 550025 According to the vibration of cut blasting, the number of holes and the location of holes are reasonably designed by using finite element software LS-DYNA. The rectangular holes and hollow holes in straight cut are simulated respectively. Of the hole in the straight-cut undercut blasting vibration law. The analysis shows that the larger the diameter of the hole is, the better the vibration reduction is. The more the number of holes is, the more obvious the damping effect is. The best blasting effect of the large diameter hollow hole and the large diameter rectangular hole is 0.93cm/s Reduce the blasting vibration speed, buffered the blasting time; get both a good blasting effect and effective rapid damping effect.

UNDERSTANDING HOW TO REACH THE HARD TO REACH IN CANCER REHABILITATION

Research Article of Global Journal of Nursing Understanding how to reach the hard to reach in cancer rehabilitation Jenna Smith-Turchyn PT, PhD1,2*; Madison F Vani MSc, PhD(c)1; Catherine M Sabiston PhD1 1Faculty of Kinesiology and Physical Education, University of Toronto, Toronto, Ontario, Canada. 2School of Rehabilitation Science, McMaster University, Hamilton, Ontario, Canada. Introduction: Regular exercise helps manage side effects of cancer treatment, however, less than 30% of survivors participate in regular exercise. Exercise-related barriers, facilitators, and needs of general populations of cancer survivors are described in the literature. No information exists describing this information for hard to reach populations. Purpose: To determine the barriers, facilitators, and exercise needs of hard to reach cancer survivors. Materials and Methods: Research design: Descriptive qualitative study. Population: Hard to reach cancer survivors, including young adults (18-39 years), those living in rural communities, and those living in areas of low socioeconomic status. Data collection: Semi-structured interviews were conducted with participants. Interviews were audio recorded and transcribed verbatim. Transcripts were coded independently by two researchers. Coded data was aggregated into nodes and grouped into themes. Results: Five themes were identified that influence exercise participation in hard to reach survivors: accessibility of exercise programs, appropriateness of exercise programs, social support, personal factors, and exercise information. Young adults described a lack of appropriate exercise programs for their age group, those in rural settings described availability issues, and those in areas of low SES described cost and social support as barriers to exercise. Conclusion: This project identified unique exercise-related barriers, facilitators, and needs of hard to reach cancer survivors. Results can be used by researchers and clinicians when creating exercise interventions for cancer survivors. Interventions must be tailored to the specific needs of each individual in order to facilitate accessible participation in regular exercise and facilitate sustained behaviour change ...

Pseudo-endocarditis secondary to ruptured posteromedial papillary muscle with anatomical variation: A Case Report

Case Report of International Journal of Case Reports Pseudo-endocarditis secondary to ruptured posteromedial papillary muscle with anatomical variation: A Case Report Natassja Moriarty, MBBS1*; Jonathan Moriarty, MBBS2; Nadeem Attar,MBBS3; Adrian Brodison, MB chB4 1,2Department of Medicine, Furness General Hospital. 3,4Consultant Cardiologist, Furness General Hospital. Myocardial infarction is the leading cause of papillary muscle rupture. This complication occurs in up to 5% of cases post MI and although rare, it constitutes a cardiac emergency if left untreated. On this basis, a 59-year-old male presented with low-grade fever and atypical chest pain with raised inflammatory markers and troponin levels.  He was treated for infective endocarditis after echocardiography revealed a mass on the mitral valve, which was presumed to be a mitral valve vegetation and so he completed a 6-weeks course of antibiotics followed by elective mitral valve replacement surgery. During surgery, it was discovered that there was no endocarditis. Instead an unusually small muscle head of one of the posteromedial papillary muscle groups had ruptured secondary to an inferior myocardial infarction. This ruptured muscle head was highly mobile and mimicked a mitral valve vegetation. The mitral valve was successfully repaired, and the right coronary artery grafted. He made a full recovery but developed new-onset atrial fibrillation for which he is awaiting elective cardioversion. One should have a high index of suspicion for diagnosing papillary muscle rupture as it may mimic valvular vegetation on echocardiography, especially if the papillary muscle involved is an anatomical variant.

SEMI-RIGID LUMBAR SPINE FIXATION WITH PEEK RODS AS A TREATMENT OPTION FOR MONO-SEGMENTAL DEGENERATIVE DISK DISEASE

Research Article of American Journal of Orthopedic Research and Reviews Semi-rigid lumbar spine fixation with PEEK rods as a treatment option for mono-segmental degenerative disk disease Michael Winking MD, PhD1*, Mags Wigram PhD1 1Spine Center, Klinikum Osnabrueck, Am Finkenhuegel 3 D-49076 Osnabrueck, Germany. Long lasting back pain due to degenerative disc disease is one of the major reasons for reduced quality of life and work incapacity. In some of these patients conservative treatment will not improve back pain significantly. Therefore fusion surgery as a surgical option is offered to these patients. The main aim of this kind of treatment is the reduction of segmental motion leading to an improvement in pain. Rigid fixation leads to high fusion rates but may also contribute to stress shielding and adjacent segment degeneration. Therefore a semi-rigid stabilization with PEEK rods may be an option because it is associated with less implant related rigidity and is a less invasive procedure. The aim of this retrospective study was to evaluate the improvement in back pain after minimally invasive semi-rigid lumbar stabilization with screws and PEEK rods in 45 patients and to identify potential implant failures during a follow up of two years. Six weeks after surgery the patients showed a significant improvement in their back pain, which persisted during the whole observation time of two years (p<0.01). All patients who were still in working life returned to their jobs without extended work incapacity. No implant related complication associated with the surgical procedure was detected. During the follow up time of two years no implant failure was observed. Keywords: PEEK rods; Semi-rigid stabilization; Lumbar degenerative disc disease (DDD); Lumbar fusion; Chronic low back pain ...
