This paper describes the design, simulation, and performance evaluation of hybrid MR damper on quarter bus semi-active seat suspension coupled with human biodynamic model. Also, whole body vibration (WBV) exposures were evaluated based international standard ISO 2631 (1997), its parameters used to measure level discomfort for drivers. The was proposed enhance damping force within low current su...

In this work we propose a multiagent architecture for web educational resources retrieval that helps users to find courses according to their personal and cultural aspects. Cultural aspects are preferences and ways of behavior determined by the person’s culture. In this work, the cultural aspects are just the features that distinguish between the preferences of users from different regions. Thi...

The hand-tool coupling force in the operation of a vibrating tool is generally composed of applied force (AF) and biodynamic force (BF). There is wide interest in quantifying the coupling force. The objectives of this study are to develop an effective method for estimating the BF and to investigate its fundamental characteristics. Using the biodynamic response of the hand-arm system, such as ap...

Surgical literature is inundated with references to Langer’s Lines, Cleavage Lines, Wrinkle Lines and Skin Tension Lines. The author undertakes a detailed literature review to understand the “state-ofthe art” regarding skin lines in cutaneous surgery and puts forward a hypothesis that incisional and excisional lines are different. While the lines mentioned above are fine for making incisions, w...

Pushing and pulling during manual material handling can increase the compressive forces on the lumbar disc region while creating high shear forces at the shoe-floor interface. A sagittal plane dynamic model derived from previous biomechanical models was developed to predict L5/S1 compressive force and required coefficients of friction during dynamic cart pushing and pulling. Before these predic...

Although much research has been devoted to constructing specific models or to measuring the response characteristics of seated subjects, investigations on a mathematical human model on a seat with a backrest to evaluate vehicular riding comfort have not yet attracted the same level of attention. For the responses of a seated body to vertical vibrations, mathematical models of the mechanisms mus...

Evidence for the role of silica in plants is reviewed with respect to the application of silicate based sprays in biodynamic agriculture. There is research indicating improved resistance to pests, disease, drought and other stresses on plants from application of silica fertilisers and sprays. There is also evidence of improved nutrient uptake. Experiments with field grown lettuce were undertake...

BACKGROUND Calcium intake in North America remains substantially below recommended amounts. Bottled waters high in calcium could help close that gap. OBJECTIVES The objectives were to summarize and integrate published absorbability and biodynamic data concerning high-calcium mineral waters and to combine these data with hitherto unpublished analyses from my laboratory. DESIGN The usual libr...
