Lifting load

"Standard Specification for Carbon Steel Chain" covers carbon steel chain for such applications as railroad cars, construction, industrial uses, load binding, and general purposes other than overhead lifting. The Grade designation is 1⁄10 of the minimum breaking strength in newtons divided by two times the nominal crosssectional area of the chain in square millimetres.

"Standard Specification for Grade 80 Alloy Steel Chain" covers Grade 80 heat-treated alloy steel chain for such applications as slings, lifting assemblies, and load binding. The Grade designation is 1⁄10 of the minimum breaking strength in newtons divided by two times the nominal cross-sectional area of the chain in square millimetres.

There is consistent evidence from observational studies of an association between occupational lifting and carrying of heavy loads and the diagnosis of hip osteoarthritis. However, due to the heterogeneity of exposure estimates considered in single studies, a dose-response relationship between cumulative physical workload and hip osteoarthritis could not be determined so far.

The flexion relaxation phenomenon (FRP) has been widely investigated. Nevertheless, no study has been reported on the FRP as well as spasm response to large lifting load. The aim of this study was to evaluate the effect of large lifting load on the FRP response and spasm during execution of a flexion-extension exercise.

Achilles tendinopathy is one of the most common overuse injuries in running, and forefoot pronation, seen in flatfeet participants, has been proposed to cause additional loading across the Achilles tendon. Foot orthoses are one of the common and effective conservative treatment prescribed for Achilles tendinopathy, it works by correcting the biomechanical malalignment and reducing tendon load.

In an effort to reduce the risk of breast cancer-related arm lymphedema, patients are commonly advised to avoid heavy lifting, impacting activities of daily living and resistance exercise prescription. This advice lacks evidence, with no prospective studies investigating arm volume changes after resistance exercise with heavy loads in this population.

Indian railway employs around 20,000 of Railway porters for the heavy load of work causing discomfort to their body in most elephantine way. Twelve porters were randomly selected from purposively selected areas, Old Delhi and Jalandhar (Punjab) Railway Stations (six from each) for the study during the busiest time of Guru Nanak Jayanti. Nordic Musculoskeletal Questionnaire was used to log the personal profile and musculo-skeletal discomfort of the respondents.

In this paper, the author proposes a method modified on-line the parameters of the PID controller based on combining the hedge algebras control and model reference system. This proposal has inherited the adaption of hedge algebras control deal with the uncertain systems or nonlinear systems and the sustainability of model reference system for load disturbances and measurement noise.

The paper presents the results of calculating the stress concentration at the link points by the method of separation of nodes in terms of conditions and load bearing design allowed. The study also shows the results of calculation after the test and the aggregation of forces in accordance with the links at the elements that need to be considered and given in the problem.

I’ve been thinking about putting this book together for several years. During two de cades of writing about nursing, I’ve read many inspirational books, articles, and essays that offer up the literary equivalent of comfort food for RNs. The authors invariably mean to be helpful to the nursing profession by lifting the spirits of its practitioners at a time when so many are feeling tired, stressed out, dispirited, or unappreciated.
