An interest in plume spectroscopy led to the development of a labscale Hybrid Rocket Facility at the University of Arkansas at Little Rock (UALR). The goal of this project was to develop a reliable, consistent rocket motor testbed for the development of plume spectroscopy instrumentation. Hybrid motor technology was selected because it has proven to be safe and inexpensive to operate. The proje...

The purpose of this study was to assess the influence of functional abilities on specificmotor skills. A total number of 92 male water polo players (age 12±0.5 years, body height 156.96±22.3 cm, body weight 51.02±33.18 kg) with at least two years' experience, were enrolled in the study. The investigation protocol consisted of standardized anthropometric measurements, estimation of maximum oxyge...

Parkinson’s disease is a neurological disorder that affects patient’s motor function including speech articulation. There is no cure for Parkinson’s disease. Speech and motor function declines as the disease progresses. Automatic assessment of the disease condition may advance the treatment of Parkinson’s disease with objective, inexpensive measures. Speech acoustics, which can be easily obtain...

Careful consideration of motor impairments, such as those documented in autism, can afford valuable insights into the neurological basis of developmental disorders. Motor signs are highly quantifiable and reproducible and can serve as markers for deficits in parallel systems important for socialization and communication. Correlations of motor signs with anatomic MRI (aMRI) measures therefore of...

objectives: the aim of this study was to compare the fine motor development between low birth weight (lbw) infants and normal birth weight infants (nbw) at the age of 8-12 months by using the peabody developmental motor scale-2 (pdms-2) . methods: this was a non experimental and cross sectional study which was conducted on the 18 lbw infants and 14 normal infants. by referring to the profile of...

BACKGROUND Although poor health conditions and decreased developmental levels have been investigated in migrant children, no study in China has focused on these children's individual motor development. OBJECTIVES This study aims to explore the prevalence of motor impairment in Chinese migrant children and to determine the contributory factors. PATIENTS AND METHODS In this cross-sectional st...

Background: Neuronal Ceroid Lipofuscinoses (NCL) is a neurodegenerative condition of lysosomal metabolism due to accumulation lipofuscin in neurons. The predominant symptoms are motor and cognitive regression, seizures, ataxia retinopathy. Speech-language disorders such as dysarthria, aphasia dysphagia have been reported.

An unavoidable reciprocal influence characterizes the mother-child dyad. Within this relationship, the presence of depression, somatization, hostility, paranoid ideation, and interpersonal sensitivity symptoms at a subclinical level and their possible input on infant motor competences has not been yet considered. Bearing in mind that motor abilities represent not only an indicator of the infant...

in most industrial applications, including overhead cranes, two motors with equal speeds are required. to meet this, different traditional and modern methods are used. in the modern methods, work is done with more precision but the cost is remarkably high, also the maintenance of equipment needs specialized personnel. among traditional methods, the two-motors selsyn method is noteworthy due to ...
