The Design, Construction, and Operation of a Guarded Hot Box

The guarded hot box is a device for measuring the coefficient of heat transfer through typical wall sections, and, with some modifications, through insulations. In order to determine this coefficient, it is necessary to know the temperature difference across the wall and the quantity of heat flowing through a given area of the test sample when thermal equilibrium has been reached

Spacing water points in the southern pastoral areas of Western Australia

An inadequate distribution of watering points in our pastoral lands, particularly in the saltbush/bluebush pasture, has caused localisized land degradation close to waters and reduced animal productivity (particularly in stressful times). From experimentation and observation, some generalised recommendations for water supply distribution in pastoral areas can be made.https://researchlibrary.agric.wa.gov.au/bulletins/1233/thumbnail.jp

DOE-NE Light Water Reactor Sustainability Program and EPRI Long-Term Operations Program ? Joint Research and Development Plan

Nuclear power has contributed almost 20% of the total amount of electricity generated in the United States over the past two decades. High capacity factors and low operating costs make nuclear power plants (NPPs) some of the most economical power generators available. Further, nuclear power remains the single largest contributor (nearly 70%) of non-greenhouse gas-emitting electric power generation in the United States. Even when major refurbishments are performed to extend operating life, these plants continue to represent cost-effective, low-carbon assets to the nation's electrical generation capability

The Evolution of ADHD: A Disorder of Communication?

Attention deficit hyperactivity disorder (ADHD) is the most commonly diagnosed psychiatric condition. Many believe that the central disability is impaired inhibition, which leads to reduced abilities in social skills, self-control, organization and time management. The behaviors identified by clinicians as problematic-inattention, hyperactivity and impulsivity-have been incorporated into several evolutionary models as selectively adaptive cognitive skills for surviving the challenges of a variable Pleistocene environment. We propose that the disabilities exhibited by individuals with ADHD are maladaptive, and we concur with Barkley that there is a central impairment in the behavioral inhibition system. The underlying neural anatomy and physiology support the possibility that neurotransmitter pathology may have an impact on other interlinked systems (including language), and may also account for the frequent comorbidity of aggression, anxiety, depression, and learning disabilities (many of which are language-related). Language skills compete with other cognitive activities for the attentional system, and thus the evolution of language could not in fact be independent of the evolution of attention. If language represents the ultimate expression of the attentional system, and some individuals with ADHD are seriously impaired in the coordination of interlinked neural systems (including language), then ADHD fits Jerome Wakefield\u27s definition of harmful dysfunction, and communication impairments should be investigated more thoroughly by clinicians

Plant-Parasitic Nematodes in Iowa: Longidoridae and Trichodoriadae

Plant-parasitic nematodes, although common, are little known in Iowa. Many are important plant pathogens. This paper documents the nine species of Longidoridae and Trichodoridae known in Iowa. These are Longidorus breviannulatus, L. crassus, L. macromucronatus, L. sylphus, Xiphinema americanum, X. bakeri, X. chambersi, Paratrichodorus minor, and Trichodorus proximus
