Objective Work-related Musculoskeletal Disorders (MSDs) happen due to risk factors during work, across the world, especially in developing countries. Multiple risk factors (physical, psychosocial and mental) have contributed in MSDs as with most chronic diseases. Several tools are used to evaluate these risk factors. Quick Exposure Check (QEC) is one of the most accurate and quick-response tool...
In quantum information processing operations are often processed alongside measurements which result in classical data. Due to the gain of measurement outputs non-unitary dynamical processes can take place on system, for common channel descriptions fail describe time evolution. Quantum correctly treated by means so-called instruments capturing both and post-measurement states. Here we present a...
A unitary t-design is a powerful tool in quantum information science and fundamental physics. Despite its usefulness, only approximate implementations were known for general t. In this paper, we provide circuits that generate exact t-designs any t on an arbitrary number of qubits. Our construction inductive practical use small systems. We then introduce tth-order generalization randomized bench...
We use density-matrix simulations to study the performance of three distance quantum error correction (QEC) codes in context rare-earth (RE) ion-doped crystal platform for computing. analyze pseudothresholds these when parallel operations are not available, and examine behavior both with without resting errors. In RE systems, errors can be mitigated by extending system's ground-state coherence ...
مقدمه: اختلالات عضلانی – اسکلتی مرتبط با کار به عنوان یکی از مشکلات سلامتی عمومی در سراسر دنیاست و علت اصلی ناتوانایی ها به شمار می رود. هدف از تحقیق حاضر، بررسی شیوع اختلالات عضلانی - اسکلتی مرتبط با کار معلمان شهر اصفهان و تأثیر 8 هفته تمرینات اصلاحی منتخب و مداخلات ارگونومی بر آنها بود. روش ها: بدین منظور از پرسشنامه نوردیک برای مطالعه شیوع اختلالات عضلانی - اسکلتی مرتبط با کار و همچنین برا...
musculoskeletal disorders have devoted a high percentage of occupational injuries and is one of the leading causes of occupational injuries and disabilities in industrialized and developing countries. the aims of this study were to evaluate exposure of musculoskeletal disorders risk factors by quick exposure check (qec) technique and to determine prevalence of musculoskeletal disorders and thei...
Background & Objectives: In Economic and competitive world today,cost-benefit analysis is one of the most important parameters for any intervention.The purpose of thisstudy was cost-benefit analysis of ergonomic interventions effects in Boiler and Equipment Engineering and Manufacturing Company. Methods:At first all workstations of the company assessed using QEC. Thenthose earned more than 7...
Introduction: Musculoskeletal disorders are one of the most common causes of occupational injuries and disability in industrialized and developing countries. The purpose of this study was to investigate the prevalence rate of musculoskeletal disorders (MSDs) and to conduct posture assessment among workers of Yazd Electrode Company. Methods:This cross-sectional study was conducted among 59 prod...
Introduction: Musculoskeletal disorders are one of the prevalent factors that lead to absenteeism at work. The purpose of this study was to evaluate the physical posture and methods to improve workstations in the petrochemical industry. Methods: This interventional study was carried out at the Petrochemical Company and according to the type of work and posture evaluation using two methods QEC a...
