Abstract: The invention provides an easy-to-use method of containing consistent growth and yield values at varying levels of resolution (stand, size-class) for loblolly pine plantations in the southern United States. The invention is able to make projections of estimated values using either existing stand data, or predicted from bare-ground conditions. The invention evaluates stand performance based on estimates of potential or "target" productivity yields. The invention provides long-term expected yields for strategic planning, and short term projections for inventory purposes. The invention can function as a simulation tool to provide insights into the life-cycle of a stand under varying initial conditions. While most growth and yield models use an empirical, multiple regression, "best fits to the data" modelling methodology, the present invention is based upon a biomathematical modelling concept.

Abstract: The invention is to an apparatus for holding and moving a needle for drawing blood from a finger. The apparatus includes a tubular body for receiving a needle, and a cap, with a needle point opening, for closing one end of the tubular body. First, second and third levers for are used for moving the cap to open the end of the tubular body, for ejecting a needle from the apparatus, and for releasing the needle from a cocked position to push the needle into a finger held against the closed cap.
