در این مقاله تأثیرتخمین فعالیت های آتی خورشیدی، ضریب پسا و جریان های اتمسفری بر نرخ کاهش ارتفاع و عمر مداری یک ماهواره کم ارتفاع بررسی می شود. برای این منظور از تخمین گر مداری استفاده شده که صحت عملکرد آن توسط نرم افزارsatellite tool kit تأییدشده است. در تحلیل موقعیت از پارامترهای غیرتکین مدار استفاده شده و با توجه به ارتفاع پروازی ماهواره های کم ارتفاع، شتاب اغتشاشی ناشی از توزیع غیرکروی جرم ز...

BACKGROUND The Multiple Sclerosis Impact Scale-29 (MSIS-29) has been increasingly used to evaluate the self-perceived impact of multiple sclerosis (MS) on a patient. OBJECTIVES The aim of this study was to evaluate the psychometric properties of the Finnish version of MSIS-29 in patients with MS. METHODS A total of 553 patients with MS completed the MSIS-29 and self-administered questionnai...

INTRODUCTION The MSIS-29 was developed to assess the physical and psychological impact of MS. The aims of this study were to use the responses to the MSIS-29 via the web portal of the UK MS Register to: examine the internal properties of the scale delivered via the internet, profile the cohort, and assess how well the scale measures impact of disability on the potential workforce. METHODS Bet...

Introduction At present, the treatment of osteoporotic defects poses a great challenge to clinicians, owing to the lower regeneration capacity of the osteoporotic bone as compared with the normal bone. The guided bone regeneration (GBR) technology provides a promising strategy to cure osteoporotic defects using bioactive membranes. The decellularized matrix from the small intestinal submucosa (...

Assessment of nitrogen content from crop leaves has been of interest worldwide to help growers adjust N fertilizer rates to meet the demands of the crop. A multi-spectral imaging system was developed for in-field real-time assessment of plant nitrogen stress in corn (Zea mays L.) crops indicated by plant reflectance and measured using a vision-based multi-spectral imaging sensor (MSIS). The obj...

BACKGROUND Musculoskeletal injuries (MSIs) persist as the leading category of occupational injury in health care. Limited evidence exists regarding MSIs for occupations other than direct patient care providers. An evaluation of the risks, causes and activities associated with MSIs that includes non-patient care health care occupations is warranted. AIMS To examine the risks and causes of time...

BACKGROUND Multiple Sclerosis (MS) is a degenerative neurological disease that causes impairments, including spasticity, pain, fatigue, and bladder dysfunction, which negatively impact on quality of life. The Multiple Sclerosis Impact Scale (MSIS-29) is a disease-specific health-related quality of life (HRQoL) instrument, developed using the patient's perspective on disease impact. It consists ...

BACKGROUND There is increasing emphasis on using patient-reported outcomes (PROs) to complement traditional clinical outcomes in medical research, including in multiple sclerosis (MS). Research, particularly in oncology and heart failure, has shown that PROs can be prognostic of hard clinical endpoints such as survival time (time from study entry until death). However, unlike in oncology or car...

AIM The aims of this study were to determine the reliability, responsiveness and minimally important change score of the Multiple Sclerosis Impact Scale (MSIS)-29 physical using the Expanded Disability Status Scale (EDSS) as an anchor measure. METHODS 214 patients with multiple sclerosis (MS) (EDSS 0-8.5) had concurrent MSIS-29 and EDSS assessments at baseline and at up to 4 years of follow-u...
