The topographic diagnosis of acquired nystagmus in brainstem disorders.

2002

Evidence is presented for a clinical classification of central vestibular syndromes according to the three major planes of action of the vestibulo-ocular reflex (VOR): yaw, pitch, and roll. The plane-specific vestibular syndromes are determined by ocular motor, postural, and perceptual signs. Yaw plane signs are horizontal nystagmus, horizontal past pointing, rotational and lateral body falls to the right or to the left, and horizontal deviation of perceived straight-ahead. Pitch plane signs are upbeat/downbeat nystagmus, forward/backward tilts and falls, and upward or downward deviations of the perceived horizontal. Roll plane signs are torsional nystagmus, skew deviation, ocular torsion, …

Comparative study of the effect of gentamicin on the vestibulo-ocular and visual vestibulo-ocular reflexes in the cat.

1991

The ototoxic effect of an aminoglycoside, gentamicin, on the vestibular system was investigated in cats given daily doses of 40 mg/kg i.m. for 14 days. Periodically, measurements were made of the vestibulo-ocular reflex (VOR) and visual vestibulo-ocular reflex (ViVOR) responses induced by rotatory stimuli at various frequencies from 0.0125 Hz to 0.8 Hz. After the cessation of drug administration, a progressively declining response to VOR stimuli continued, manifested by gain (ratio of peak response to peak stimulus amplitude) and phase relationships. The ViVOR was affected only in the gain measurements. The changes in the response amplitude (gain) were greater for the VOR than for the ViVOR…

Vertigo, Masseter Paresis or Masseter Reflex Abnormality, and Impaired Caloric Response

1993

Symptoms and signs of acute peripheral-type vestibular abnormalities occasionally occur in patients with multiple sclerosis and brain-stem ischemia. Such patients may show reduced excitability of the lateral semicircular canal. From this observation, the question arises as to the location of the causative lesion.

Analysis of EMI Shielding Effectiveness for plastic fiber composites in the 5G sub-6 GHz band

2021

The study and modeling of EMC are becoming more critical than ever due to the ubiquitous presence of electronic circuits in all aspects of our lives. Specifically, it is crucial to extend these studies to the new frequencies that, in a few years, will be a reality in modern telecommunications systems, such as 5G and its derived technologies. A specific critical field where the proper EMI shielding has been ensured to avoid EMC problems is the electric autonomous vehicles (EAVs). The huge number of electronics systems in new vehicles will dramatically extend the demands on the EMI shielding solutions used to attenuate the radiated emissions that could affect circuits in the vehicle.

Travelling Strings, Beams, Panels, Membranes and Plates

2013

In this chapter, we will introduce in a general manner some of the most common models for axially travelling materials, which will be used in the rest of the book. We will introduce the linear models of travelling strings, panels, and plates. It will be assumed that the material is thin, i.e. its planar dimensions are much larger than its thickness. We will work in the small displacement regime, that is, with linear models approximating the behaviour of the system near the trivial equilibrium. As is well known in the theory of elasticity, this approximation allows for a decoupling of the in-plane and out-of-plane components in the dynamics of the system. We will concentrate on small out-of-…

Ādas vazomotorā aksonrefleksa novērtējums, izmantojot bezkontakta fotopletizmogrāfijas metodi

2020

Bakalaura darba “Ādas vazomotorā aksonrefleksa novērtējums, izmantojot bezkontakta fotopletizmogrāfijas metodi” mērķis ir izvērtēt bezkontakta fotopletizmogrāfijas iespējas matainās ādas vietējās sildīšanas izraisīto vazomotoro reakciju kvantitatīvajā novērtēšanā. Pētījumā piedalījās 13 brīvprātīgie, kas bija klīniski veseli un bez kaitīgiem ieradumiem. Mērījums noritēja, sildot uz plaukstas virspuses novietotu sildelementu, kas atradās starp kontroles un EMLA krēma anestezēto zonu. Video ieraksts notika 20 minūtes – pirmajā minūtē sildot ādu 32°C temperatūrā, bet pārējās 19 minūtes 42°C temperatūrā. Video fotopletizmogrāfiskais signāls no kontroles un EMLA zonas tika analizēts custom-made …

CLINICAL AND NEUROPHYSIOLOGICAL FINDINGS IN 47 LONG-TERM SURVIVORS OF CHILDHOOD MALIGNANCIES TREATED WITH VARIOUS DOSES OF VINCRISTINE

1978

ABSTRACT 96 long-term survivors of cancer in childhood were reexamined after succesful therapy. In 49 who had not been treated with VINCRISTINE (VCR) reflex status and motor conduction velocities were normal. In contrast, 47-after treatment with VCR-had loss of deep tendon reflexes in a high rate and a prolongation of sensory CV independent of the 1 total cumulative dose of VCR, 2 application mode according to different treatment regimen, 3 time interval since the last injections of the drug, 4 age of children at onset of therapy.

Effect of TiO2 on the mullite formation and mechanical properties of alumina porcelain

2010

Abstract The effect of adding TiO 2 to standard alumina porcelain on its microstructure and flexural strength was investigated. A series of alumina porcelain bodies containing increasing amounts of TiO 2 were prepared by extruding mixtures of raw materials and TiO 2 . Porcelain rods were fired under industrial scheduling in a manufacturing kiln. The overall degree of crystalline and amorphous phase content within the porcelain bodies was quantitatively determined using a Rietveld analysis. Results indicated a higher amount of mullite formation in porcelain bodies containing TiO 2 . Examination of the product materials using field emission scanning electron microscopy showed a high density o…
