High Torque Low Current (HTLC) Starter is the new innovative motor soft starter system. This is a motor starting method for high inertia loads using a low voltage drive with input and output transformers to control motor torque and limit current when starting a medium/high voltage motor. The HTLC is a solution to motor starting problems where Direct on Line (DOL) or “Across the Line” starting i...

An Analog Memory suitable to storage a fotogenerated image frame is described. An architecture that allows a fast writing rate is presented. The Memory has a serial input and eight channels parallel output; it can store a QCIF image (176x144 pixels) for 1/15 sec with an equivalent precision of 7bit. Nominal input writing frequency is 2,5MHz and output reading frequency is 0,833MHz. The CHIP nee...

In this paper, the design of a waveguide fixtuned 220GHz subharmonically pumped mixer using Schottky planar diodes is demonstrated. It is supposed to be applied in an experimental short-range and high-speed communication system. The anti-parallel pair of planar Schottky diodes from the Rutherford Appleton Laboratory (RAL) was flip-chip mounted and soldered onto a suspended 75μm-thick quartz mic...

Insulin-like growth factor 1 receptor (IGF-1R) is a main receptor of IGFs family which plays a critical role in the postnatal growth and skeletal growth in many species. However, there are few reports of IGF-1R gene structure and its effects on growth traits in sheep. The objectives of this study were detection of IGF-1R polymorphisms and assessment of their associations with ...

Changes in the biomechanics of gait may alter the energy requirements of walking in Parkinson's Disease (PD). This study investigated economy of gait during submaximal treadmill walking in 79 subjects with mild to moderate PD and the relationship between gait economy and 6-minute walk distance (6 MW). Oxygen consumption (VO(2)) at the self-selected treadmill walking speed averaged 64% of peak o...

BACKGROUND Tai Chi training enhances physical function and may reduce falls in older adults with and without balance disorders, yet its effect on postural control as quantified by the magnitude or speed of center-of-pressure (COP) excursions beneath the feet is less clear. We hypothesized that COP metrics derived from complex systems theory may better capture the multi-component stimulus that T...

Dyspnea brought on by exercise is one of the basic symptoms of patients with chronic obstructive pulmonary disease (COPD). It appears in the initial phases of the disease, affects activities of daily living,1 and determines, to a large extent, the perception of the degree of illness and extent of deterioration in quality of life. Tolerance to exercise in these patients is an indicator of severi...
