    Product safety problems really waste company resources, alienate consumers, frustrate employees, and leave company stakeholders disgusted. It is easy to understand why most consumer product companies are committed to product safety and why they often seem willing to devote even more resources to increase their organization s safety commitment. Their logic seems to be that this kind of action will result in higher levels of safety performance. Achieving excellence in product safety is not about seeking more commitment. It is all about understanding what to do and how to do it using the fine organization one already has. Product Safety Excellence defines the seven vital elements that are essential to achieving state-of-the-art product safety performance with the benefits of product liability prevention, product quality improvement, and higher levels of consumer trust and loyalty.
    Timothy A. Pine
    This book is intended to reduce and simplify into a vital few basic elements the foundation that will enable excellence and competitive advantage. It is also intended to provide guidance and reference for strategic and business planning to improve effectiveness, efficiency, and consumer loyalty. Tim Pine, a former executive at Hasbro and a manager at Nike (among others), reduces the key to achieving sustainable quality excellence to just seven necessary elements.

    Cooling for indoor Grow Ops involves more than simply adding up the lighting watts and converting that into cooling tons. Plants release a surprising amount of moisture into the air (by transpiration, plus evaporation from the soil), and this has to be accommodated as latent load in the air conditioning equipment. The result when using standard air conditioning equipment for dehumidification will often be over-cooling or insufficient dehumidification. Adding in-room dehumidifiers can help, however they normally reject the heat from the process back into the room, which the air conditioning equipment needs to remove.

    I expect that in the future architects, owners, engineers, and occupants will work together to “engineer” buildings as active, “living” systems that put more energy back into the grid than they use and also help to clean the air and water in the nearby communities.

    Rail residual stress distributions can be complex and variable in nature, as different manufacturing techniques produce varying stress magnitudes and distributions. To evaluate the effect of residual stresses on rail integrity, an analysis technique was sought that could quantify the effect of these stresses on web crack propagation.

    The computer program LS-DYNA3D was used to simulate the behavior of a specific, though representative, heavy truck cab-over tractor-trailer vehicle during a full 180° rollover event. These simulations provide a key component in the development of a physical testing procedure for evaluating structural integrity and occupant crash protection system designs in heavy trucks.
