Stress and fatigue analysis of SVI-tested camshaft lobes
… opening ramp of the most abusively ground cam lobes. No clear evidence was found for subsurface cracking at depths as great as 200 μm from the lobe's surface. Profilometry results show no evidence of any major tribological effect due to the sliding friction of the follower. Fractography studies …

Emotional biases in confabulation : the role of the frontal lobes
The neuropsychological understanding of confabulation has recently been enriched by the finding that confabulating patients present positive emotional biases in their false recollections. The exact mechanisms of this motivational phenomenon have been heuristically linked to the frontal lobe …

Reduction of Near-Field Grating Lobes in Sparse Acoustic Phased Arrays
… than one half-wavelength will produce grating lobes that decrease the usefulness of the array. With many array configurations, the near-field and far-field character of these lobes is significantly different -- an optimization of the array configuration to reduce grating lobes in the far-field …

Analysis of Cell-Cell Interactions in the Formation of Drosophila Antennal Lobes
The human orthologs of Neuroglian and Limk have been linked to human nervous system diseases, CRASH syndrome and Williams syndrome, respectively. The characterization of these two conserved genes in the Drosophila brain extends our knowledge of their cellular functions and helps to shed light on …

GABA as a Putative Neurotransmitter in the Optic Lobes of the Crab HEMIGRAPSUS NUDUS
… GABA as a putative neurotransmitter in the optic lobes of the crab <em>Hemigrapsus nudus, </em></p> <p>light microscope autoradiography ( LM ARG ), light microscope immunocytochemistry ( LM ICC ), and neurochemical techniques were employed. ARG labeling of <sup>3</sup>H-GABA was observed over …

Dreaming and the dorsolateral frontal lobes : towards a better understanding of the mechanism of dreaming
The exact mechanism of dream production is still poorly understood. Based on exploratory findings that damage to the dorsolateral prefrontal cortex does not cause changes in these patients subjective experience of their dreams (Solms, 1997), a study was conducted in order to investigate the role of …

A Functional Cerebral Systems Approach to Depression: Contributions of the Left and Right Frontal Lobes
… (and dysfunction) of the right and left frontal lobes. They go on to explain that each frontal lobe may have a direct influence on patterns of depression symptomology. In the current experiment there was an effort to look at performance differences among depressed and non-depressed males on a …

EEG activation patterns in the frontal lobes of stutterers and nonstutterers during working memory tasks
Developmental stuttering is a physiological disorder of speech motor control. Unlike acquired conditions, developmental stuttering is responsive to fluency-inducing conditions involving the manipulation or elimination of auditory feedback. It was hypothesized that stutterers experience interference …

Porosity Development Within Lobes to Downslope Ramp Deposits on a Prograding Carbonate Shelf of the Kinderhookian to Osagean Series in Northwest Arkansas
<p>Carbonate bodies with lobate geometries form a substantial part of the Osagean (early Mississippian) section in northwest Arkansas. The purpose of this study is to isolate and describe a single lobe from three-dimensional exposures in quarry walls to provide criteria by which lobe and lobe …

A Comparison of Liver Biopsy Techniques in Dogs
… and the variability of histopathology among lobes is unknown. Hypothesis: Liver biopsy specimens obtained via punch, cup biopsy, and 14 gauge needle biopsy would result in similar histopathologic diagnoses to those found on deeply sectioned samples of liver obtained at necropsy and that …

Volcanic architecture of the Deccan Traps, western Maharashtra, India: an integrated chemostratigraphic and paleomagnetic study
… The lava pile is dominated by pthoehoe sheet lobes and smaller lobes and toes. It can be divided into flow-fields, the products of one eruption, by the occurrence of weathering horizons. Palaeomagnetic results demonstrate that the chron 29R/29N reversal boundary horizon occurs in all four of …

The Localization of GABA-Like Immunoreactivity in the Optic Lobe Neuropils and Optic Tracts of the Cockroach Leucophaea Maderae
… for L. maderae has been localized to the optic lobes of the brain, the discovery of GABA-like immunoreactivity in the optic lobes and optic tract could be an important first step in localizing cells that comprise the circadian oscillator(s) that control the temporal pattern of many …

Assessment of Sediment Runoff from Natural Gas Well Development Sites.
… and weirs, and by measuring sediment debris lobes. Sediment primarily consisted of silt and clay sized particles. Sediments from two gas well sites formed five debris lobes that ranged in size from 325 to 3,290 square feet. Sediment loadings estimated from the debris lobes averaged 57.1 tons …

Mixing And Transport In The Kelvin-Stuart Cat Eyes Driven Flow Using The Topological Approximation Method
… occurs through the transfer of turnstile lobes, and that transport rates are equal to the area of the lobes transferred. Lobes may intersect, necessitating the calculation and removal of lobe intersection areas. The TAM requires the use of a Melnikov integral function, the zeroes of which …

Taxonomy, Biogeography and Pest Status of Marmara sp. in Northern Mexico and California Citrus Production
… the male genitalia; which include the valvular lobes, costal lobes, cucullar lobes, and the aedeagus. The sclerotized parts were methodically dissected and mounted on microscope slides. Digital images captured of the slide-mounted specimens proved to be inconsistent with the illustrations …

A Study to Demonstrate the Immediate Destination of an Embolus Formed in the Lumen of a Peripheral Venous Catheter
… to determine the location of each clot. The lobes were homogenized separately, and the level of radioactivity of samples from each was determined by a Well Scintillation Counter.</p> <p>The data showed that 90.91 percent of the clots lodged in the lungs and 9.09 percent within the circulatory …

Frequency specific deficits in schizophrenia
… in schizophrenia. Coherence between different lobes of the brain from task related data at different frequency bands was investigated in patients with Schizophrenia (SP) and Healthy Normal Volunteers (HNV). The task was aimed to study the neural mechanisms underlying auditory and visual …

A rapid, non-destructive test to detect camshaft lobe grinding burn
… with each of their eight induction hardened lobes receiving a different depth of cut per pass. X-ray residual stress measurements made with depth identified significant near-surface tensile residual stresses in abusively ground regions of the lobes. Acid etching at the time of grinding and …

Frontal-lobe mediated word retrieval in Parkinson's disease
… functioning, which is mediated by the frontal lobes of the brain. Tests of verbal fluency have been used to evaluate frontal lobe dysfunction. Letter fluency, however, may require different processes and mechanisms than semantic fluency. Martin and colleagues (1994) found that letter fluency …
