    A taxonomic treatment, in which the genus Steironema, consisting of three species in Iowa, is united with the genus Lysimachia in accordance with the opinion of recent students of these members of the primrose family. Of the total of six species, three require changing of the specific epithet

    Chemical Utilization of Aspen

    Get PDF
    Chemical utilization of raw materials depends largely on the chemical composition and the chemical and physical properties of the raw materials under consideration. The utilization of wood is no exception to this principle. Thus, a wood having a low percentage of cellulose is uneconomical as a source of wood sugar or pulp for paper; and one of an excessively knotty character is undesirable for chemical conversion Woods having several undesirable characteristics generally fall within the classification of species little used for the purpose. Fortunate! aspen falls outside this class

    Sensory Pollution from Bag Filters, Carbon Filters and Combinations

    Used ventilation filters are a major source of sensory pollutants in air handling systems. The objective of the present study was to evaluate the net effect that different combinations of filters had on perceived air quality after 5 months of continuous filtration of outdoor suburban air. A panel of 32 subjects assessed different sets of used filters and identical sets consisting of new filters. Additionally, filter weights and pressure drops were measured at the beginning and end of the operation period. The filter sets included single EU5 and EU7 fiberglass filters, an EU7 filter protected by an upstream pre-filter (changed monthly), an EU7 filter protected by an upstream activated carbon (AC) filter, and EU7 filters with an AC filter either downstream or both upstream and downstream. In addition, two types of stand-alone combination filters were evaluated: a bag-type fiberglass filter that contained AC and a synthetic fiber cartridge filter that contained AC. Air that had passed through used filters was most acceptable for those sets in which an AC filter was used downstream of the particle filter. Comparable air quality was achieved with the stand-alone bag filter that contained AC. Furthermore, its pressure drop changed very little during the 5 months of service, and it had the added benefit of removing a large fraction of ozone from the airstream. If similar results are obtained over a wider variety of soiling conditions, such filters may be a viable solution to a long recognized problem

    COVID-19 and fear processing

    Get PDF
    The world faces a global crisis that encompasses health, financial, and psychological aspects as a result of the coronavirus disease. While the health crisis is significant, it is important to recognize that the human and social crises that have emerged are equally impactful. These crises have resulted in various negative outcomes, such as social rejection, economic disparity, unemployment, and mental distress. Fear is a significant psychological barrier that can impede recovery from any disease process, and thus, it plays a critical role in determining the mortality and morbidity of any given disease. The COVID-19 pandemic has generated a pervasive fear of infection that has further exacerbated the situation. This study explored the mechanisms by which humans may have elicited conditional fear, using the COVID-19 pandemic as a specific case study. Our goal was to examine the process of fear in humans by exploring our knowledge of neuroanatomy and the systemic response regulated by the autonomic nervous system
