Computer simulations using multibody models have been extensively applied to vehicular crash testing but have rarely been used to investigate falls. This article investigated planar and three-dimensional simulations of a single physical test of a Hybrid III anthropomorphic test dummy falling from a bed and compared them with a common estimation method. The effects of initial model position and ...
One of the types of water erosion and land degradation which causes imbalance in the area of natural resources and agricultural land and gives heavy losses, is the gully erosion phenomenon. To control this phenomenon, It is important to understand the influence factors on the geometry specification. Land degradation, a broken ecological balance of the land and landscape and risk of falling at b...
A year-long prospective study of injuries caused by armoured fighting vehicles on exercises in West Germany revealed that 2 soldiers were killed. Another 41 needed hospital admission for treatment of injuries of the lower limb (16), upper limb (15), head (8) and back (2). Tank loader/signallers were peculiarly susceptible to severe leg injuries, due to the ankle being trapped and twisted by the...
Fanged frogs (Limnonectes) are a group of dicroglossid frogs from Asia that often have reversed sexual dimorphism with larger males. Limnonectes dabanus is a poorly known species of fanged frog from forested habitats in southern Vietnam and eastern Cambodia. Adult males exhibit an extreme degree of megacephaly and possess bizarre head ornamentation. L. dabanus breeds in shallow, non-flowing or ...
Winter rye, with all its advantages (adaptability, stress resistance, increased productivity), cannot compete other grain crops, and the reason is quality to a greater extent. Solution of issue possible when cultivating rye varieties low content water-soluble pentosans in grain. In Western Siberia, winter has traditionally been considered leading crop, which efficiently uses environmental resou...
Fractures of the radial head and radial neck correspond to 1.7-5.4% of all fractures and approximately 30% may present associated injuries. In the literature, there are few reports of radial head fracture with posterior interosseous nerve injury. This study aimed to report a case of radial head fracture associated with posterior interosseous nerve injury. CASE REPORT A male patient, aged 42 y...
Using test dummy experiments to investigate pediatric injury risk in simulated short-distance falls.
BACKGROUND Short-distance falls, such as from a bed, are often falsely reported scenarios in child abuse. In attempting to differentiate between abusive and nonabusive injury, knowledge of factors that affect injury risk in falls could prove useful. OBJECTIVES To assess the biomechanics associated with simulated short-distance falls in children (one fall scenario, without attempting to maximi...
background & objectives : trauma is one of the major causes of morbidity and mortality in different countries. road accidents are the main causes of death due to trauma. the injury resulted from traffic accident is one of the neglected problems of public health whose follow-up is necessary. the purpose of this survey is to study the epidemiology of injuries and their causes in traumatic pati...
CASE REPORT A 79-year-old woman sustained a left anterior column acetabulum fracture after falling on ice. On initial presentation to the emergency room she was placed in femoral pin traction. The reduction of the acetabulum in traction was not concentric and the femoral head began to migrate centrally. Treatment options, including primary THA after the acetabulum fracture healed, were discusse...
Abstract Salt weathering is a major concern for cultural heritages such as ruins and tombs, desalination by poulticing an interesting potential method to efficiently remove contaminating salt. Predicting the degree of achievable very important. However, many existing models used consider saline water transport in porous materials have been developed based on theory pure water. To understand flo...
