The genetic development of the commercial broiler has led to body misconfiguration and consequent walking disabilities, mainly at slaughter age. present study aimed identify locomotion ability using image analysis automatically. A total 40 broilers that were d old (male female) placed walk on a specially built runway, their was recorded. An segmentation algorithm developed, coordinates bird’s c...

Progesterone is essential for establishment and maintenance of pregnancy in mammals. The objective of this study was to examine the effect of elevating progesterone during the different physiological stages of early embryo development on embryo survival. Estrus was synchronized in cross-bred beef heifers (n=197, approximately 2-years old) and they were inseminated 12-18h after estrus onset (=Da...

introduction: the effects of electromagnetic fields on biological organisms have been a controversial and also interesting debate over the past few decades, despite the wide range of investigations, many aspects of extremely low frequency electromagnetic fields (elf/emfs) effects including mechanism of their interaction with live organisms and also their possible biological applications still r...

locomotion fundamental skills play an essential role in improving motor development throughout the life span as they provide children with better development by enhancing search abilities in environment. this study aimed at comparing the locomotion fundamental skills in 7-year-old children with lower extremity deformities and healthy children. the statistical population consisted of 7-year-old ...

A 34-year-old man had a traumatic thoracic spinal cord injury, with vertebral fracture and a right acetabulum fracture. Dorsal spinal fusion of T6 through T9 was performed on admission. The initial American Spinal Injury Association (ASIA) Impairment Scale (C) showed incomplete motor T10 lesion. Exoskeletal locomotion training with hybrid assistive limb started 77 days post trauma after radiolo...

Broiler (meat) chickens have been subjected to intense genetic selection. In the past 50 years, broiler growth rates have increased by over 300% (from 25 g per day to 100 g per day). There is growing societal concern that many broiler chickens have impaired locomotion or are even unable to walk. Here we present the results of a comprehensive survey of commercial flocks which quantifies the risk...

Cerebellar ataxic gait is influenced greatly by balance disorders, most likely caused by lesions of the medial zone of the cerebellum. The contributions of the intermediate and lateral zone to the control of limb dynamics for gait and the adaptation of locomotor patterns are less well understood. In this study, we analysed locomotion and goal-directed leg movements in 12 patients with chronic f...

In this paper I will present new data and ideas on two interrelated questions regarding the nervous control of insect flight. The answers to these two questions may be important for understanding other aspects of insect behaviour as well. The two problems are: (1) How perfect is the motor score which is built into the thoracic ganglia? (2) How is this motor score modified when anatomical damage...

In this paper we present an approach to the gaze stabilization problem using Adaptive Frequency Oscillators to learn the frequency, phase and amplitude of the optical flow and generate compensatory commands during robot locomotion. Assuming periodic and nearly sine shaped motion of the robot, the system successfully stabilizes the gaze of the robot, whether the robot itself is moving, or an ext...
