A Centennial History of the Ohio Journal of Science

Author Institution: John N. Couch Biology Library, CB#3280-Coker Hall, University of North CarolinaOn the occasion of the centennial ofThe Ohio Journal of Science, this paper provides a short history of its development. From an inaugural issue of 16 pages in November 1900, The Journal has matured into an important serial featuring peer-reviewed articles in science, engineering, technology, and education, or their applications; book reviews; four special issues devoted to a theme; Academy presidential addresses; and obituaries of deceased members. Guided over the years by a sequence of 18 editors, The Journal has undergone title changes as its disciplinary scope broadened: The O.S.U. Naturalist (Nov-Dec 1900), The Ohio Naturalist (Jan 1901-Jun 1914), The Ohio Naturalist and Journal of Science (Nov 1914-Jun 1915), and The Ohio Journal of Science (Nov 1915-present). In the past century The Journal has developed from an Ohio natural history serial to an interdisciplinary science journal of international use and respect. Copies are sent to 1900 individuals and organizations, including 37 foreign countries

Virginia\u27s Response to Computer Abuses: An Act in Five Crimes

The threat depicted in War Games has been both rebuked as impossible and highlighted as much closer to the realm of possibility than even the creators of the movie may have surmised. Regardless of the actual possibility of a creative mind breaking through the security of the North America Air Defense Command computer with an auto-dialing modem and the simple password JOSHUA the adventures of the curious hackers and the singularly-directed criminal have been widely publicized and have captured both the fear and respect of computer owners throughout the country

Orexin A-induced enhancement of attentional processing in rats: role of basal forebrain neurons

Orexins are neuropeptides released in multiple brain regions from neurons that originate within the lateral hypothalamus and contiguous perfornical area. The basal forebrain, a structure implicated in attentional processing, receives orexinergic inputs. Our previous work demonstrated that administration of an orexin-1 receptor antagonist, SB-334867, systemically or via infusion directly into the basal forebrain, can disrupt performance in a task that places explicit demands on attentional processing. Given that the orexin-1 receptor binds orexin A with high affinity, we tested whether orexin A could enhance attention in rats. Attentional performance was assessed using a task that required discrimination of variable duration visual signals from trials when no signal was presented. We also tested whether infusions of orexin A into the lateral ventricle could attenuate deficits following lesions of medial prefrontal cortical cholinergic projections that arise from the basal forebrain. Infusions of orexin A into the basal forebrain attenuated distracter-induced decreases in attentional performance. Orexin A attenuated deficits in lesioned animals when a visual distracter was presented. The present results support the view that orexin A can enhance attentional performance via actions in the basal forebrain and may be beneficial for some conditions characterized by attentional dysfunction due to disruption of cortical cholinergic inputs

Long term study of the seismic environment at LIGO

The LIGO experiment aims to detect and study gravitational waves using ground based laser interferometry. A critical factor to the performance of the interferometers, and a major consideration in the design of possible future upgrades, is isolation of the interferometer optics from seismic noise. We present the results of a detailed program of measurements of the seismic environment surrounding the LIGO interferometers. We describe the experimental configuration used to collect the data, which was acquired over a 613 day period. The measurements focused on the frequency range 0.1-10 Hz, in which the secondary microseismic peak and noise due to human activity in the vicinity of the detectors was found to be particularly critical to interferometer performance. We compare the statistical distribution of the data sets from the two interferometer sites, construct amplitude spectral densities of seismic noise amplitude fluctuations with periods of up to 3 months, and analyze the data for any long term trends in the amplitude of seismic noise in this critical frequency range.Comment: To be published in Classical and Quantum Gravity. 24 pages, 15 figure

Surgical management of chronic otitis secondary to craniomandibular osteopathy in three West Highland white terriers

Three West Highland white terriers were presented for investigation of left‐sided para‐aural abscessation. CT revealed chronic otitis media with extensive osseous proliferation surrounding the horizontal and vertical ear canals contiguous with the expanded temporal bone, consistent with a unilateral variant of craniomandibular osteopathy. A left total ear canal ablation with lateral bulla osteotomy was performed in all dogs. An ultrasonic bone curette (Sonopet; Stryker) proved useful when removing the osseous proliferation in two dogs. Histopathological examination of the ear canals was consistent with craniomandibular osteopathy and the treatment led to resolution of the presenting clinical signs in all dogs. To our knowledge, this is the first report of craniomandibular osteopathy engulfing the external ear canal, presumably leading to chronic otitis media and para‐aural abscess formation. This is also the first reported use of an ultrasonic bone curette in canine otic surgery
