6/27/2018 · Corrosion
When thinking about the safe operation of boilers (and don't we all?), several systems can readily be named; flame control, fuel/air ratio; steam pressure control, levels in the vessel, etc. What about the water? It seems so passive, as long as there is enough for level control, what's the big deal? Well, it turns out, that as the steam produced by a boiler is used in the process, the condensate from that steam is returned to the boiler as feedwater. However, since 100% of the condensate is not returned, whatever solids had been in that water before it evaporated to form steam are left in the remaining water. Fresh feedwater is added to maintain levels, but even fresh water contains some dissolved solids. So over time, the water in the boiler system gets saturated with all sorts of dissolved minerals.

    The willingness to view risk as part of daily life has vanished. A risk-averse mindset among environmental regulators engenders confusion between the ethics of intention and the ethics of consequence, leading to the elevation of the precautionary principle with unintended and often unfortunate outcomes. Environmental risk assessment is conservative, but the actual level of conservatism cannot be determined. High-end exposure assumptions and current toxicity criteria from the USEPA, based on linear extrapolation for carcinogens and default uncertainty factors for systemic toxicants, obscure the degree of conservatism in risk assessments. Ideally, one could choose a percentile of the target population to include within environmental standards, but this choice is complicated by the food, pharmaceutical and advertising industries, whose activities, inadvertent or not, often promote maladaptive and unhealthy lifestyle choices.

    Resistance to conventional pesticides has been growing rapidly among all pests. Furthermore, there is increased public concern about the safety of conventional pesticides, and increased governmental restrictions have resulted in the need to identify new compounds that are safe and effective in controlling pests that are of concern to agriculture as well as to public and animal health. Biopesticides may aid in the control of such pests with fewer deleterious effects to the environment, people and animals.

    2/17/2002 · Expert Witnessing
    Attorneys use experts in two ways. First is the traditional use of an expert as a witness in court. In this role, scientists, business people, or others with technical knowledge are retained by attorneys primarily for their opinions (oral, written, or both), ultimately to be given at deposition and in civil and criminal courts. Second, the expert may be used as a pre-trial consultant or more specifically as an undisclosed consultant

    Olen R. Brown, PhD
    "Miracles" reveals truth from Scripture, science and life. Everything that is or was or is to come is part of God's miracle. Science says that nothing is miraculous- Time and Chance created the universe with no meaning or purpose. God's universe has great meaning extending from the stars to atoms and to you. What we believe about miracles can be a source of great joy or missed joy in our lives. Dr. Brown, a Christian and author of over 100 scientific papers, has coined a new word, synscicretism, to call attention to the doctrine that today elevates science above religion. Science works best for the great "how" questions, but poorly for the great "why" of all things.
