Influence of load carrying on loads in internal spinal fixators

Journal of Biomechanics, 2000
After spinal stabilization with an implant, patients want to know whether carrying loads will endanger their spine and their implant. Therefore, the effect of carrying a weight on the loading of internal spinal fixation devices was determined in 10 patients using instrumented, telemeterized internal fixators. Patients carried a 5kg dumbbell in one hand

Internal and External Training Load: 15 Years On [PDF]

International Journal of Sports Physiology and Performance, 2019
Exercise is a stressor that induces various psychophysiological responses, which mediate cellular adaptations in many organ systems. To maximize this adaptive response, coaches and scientists need to control the stress applied to the athlete at the individual level. To achieve this, precise control and manipulation of the training load are required. In

Internal phosphorus loading in shallow Danish lakes

Hydrobiologia, 1999
High phosphorus concentrations due to internal loading from the sediment with a strongly negative impact on lake water quality, is often seen in shallow lakes after a reduction of external loading. To analyse the nature of internal loading we studied 1. the seasonal phosphorus concentrations of 265 Danish shallow, mainly eutrophic lakes; 2.

International industry practice on power system load modelling

2014 IEEE PES General Meeting | Conference & Exposition, 2013
Power system load modeling is a mature and generally well researched area which, as many other in electrical power engineering at the present time, is going through a period of renewed interest in both industry and academia. This interest is fueled by the appearance of new non-conventional types of loads (power electronic-based, or interfaced through ...

Internal explosive loading of steel pipes

Thin-Walled Structures, 2008
Abstract A programme of numerical, analytical and experimental studies is being carried out at the University of Liverpool on seamless steel pipes 9.5 mm thick with an outer diameter of 324 mm which have been subjected to internal explosive loading.

On Biaxially Loaded Internal Cracks

International Journal of Fracture, 2001
The initiation of fracture is studied for an internally cracked large plate. The cracked plate is subjected to biaxial loading with different ratios of the normal load to the lateral load. The initiation of crack propagation is predicted by using a strain based mechanism of fracture.

Wind Loading Codes: International Users' Perspectives

Structures 2004, 2004
Most buildings are designed using wind loading codes rather than wind tunnel testing. This paper discusses some of the experiences of using a range of international codes in an international design practice. A comparison of wind loads predicted by a range of wind loading codes for two building types, a city centre tall building and an isolated low-rise

Phosphorus accumulation in sediments and internal loading

Hydrobiological Bulletin, 1986
Two simple conceptual approaches for the description of phosphorus accumulation and release from sediments are presented. The first model is a mass-balance over the well-mixed top-layer, and demonstrates the enhanced initial effect of sediment dilution on the long-term accumulation, which is magnified in the resulting internal loading, as a consequence

Using Multiple Load Vehicles for Internal Transport with Batch Arrivals of Loads

1999
In previous papers, we used a simulation model to look at how different dispatching rules can be classified, and at the effects on the performance of internal transport if the release time of loads can be forecasted using a virtual release time. We concluded that centralized rules outperform decentralized rules and that the performance of internal ...

Internal Load Distribution Effects During Fatigue Loading of Composite Laminates

1986
Two fundamental processes govern the reduction of strength and stiffness of composite laminates caused by cyclic loading, commonly called the “fatigue effect.” One process is the reduction of the strength and stiffness of the individual constituent materials in the composite, caused by events such as localized nonconservative deformation, microcrack ...
