A current controlled bistable switching element using a CW Gunn diode is reported. With modest circuits switching rates of the order of 10 MHz have been obtained. Switching is initiated by current pulses of short duration (5 10 ns). Rise times of the order of several nanoseconds could be obtained. The apparent mechanism which allows the bistable operation of the Gunn diode is the reduction in t...

The effect of cinnarizine on motor function in Parkinson's disease was evaluated in a randomised double-blind parallel study of 20 patients. Both groups were comparable in age, duration of the disease, dose of levodopa and degree of disability. A significant worsening of mobility was observed in patients treated with cinnarizine (75 mg bd), whilst no change was recorded in patients receiving pl...

conclusions the findings showed that personal, interpersonal, and functional skills can facilitate nurses’ career advancement. the effects of these skills on career advancement depend on a variety of conditions that require further studies. results the three themes extracted from the data included interpersonal capabilities, competency for career success, and personal capacities. the results sh...

BACKGROUND Determining the optimal timing and progression of mobility exercise has the potential to affect functional recovery of critically ill adults. This study compared standard care with care delivered using a mobility protocol. We examined the effects of exercise on vital signs and inflammatory biomarkers and the effects of the nurse-initiated mobility protocol on outcomes. METHODS Pros...

Mobility metrics have been widely recognised as a useful tool in comparing the performance of different mobility models of nodes in ad hoc networks. Most mobility metrics studied to date have been used in conjunction the transmission range model of communication. That is, it is assumed that if two nodes are within a given distance, r, then it can be said that a communications link exists betwee...

Whole body vibration (WBV) is a contemporary treatment modality that holds promise as an exercise training method in health-compromised individuals. A growing number of studies on individuals with Parkinson Disease are examining whether WBV improves balance and functional mobility. However, interpreting WBV studies is challenging since there is variability in the manner in which WBV interventio...

extract: physical mobility and exercise are necessary for people health. for patient with mobility limitation this issue has more importance because these exercises help them to return to normal function more effectively. since the individual planning for each patient is not time effective, so we could plan group exercises and perform properly in orthopedic wards. the important goals of this pl...

neutrophil mobility in 60 patients with vitamin d-deficient rickets is studied, and the patients are followed after therapy by 600,000 units vitamin d. 28 of 60 patients (46%), had low chemotaxis for neutrophils before vitamin d injection (migration), and 36 of 60 (60%) had low random mobility. the results showed a significant improvement after vitamin d therapy furthermore, the level of calciu...
