Evaluation of Upper Limb Muscle Activation Using Musculoskeletal Model with Wearable Assistive Device.

In recent years, wearable assistive device has been used to support upper arm movement training for rehabilitation purposes. A wearable assistive device could affect the muscle output during motor tasks to support upper limb disorder rehabilitation training. However, the investigation of muscle activity with the given assistive force is not widely investigated.

Strategies for radiology departments in handling the COVID-19 pandemic.

The world is facing an unprecedented global pandemic in the form of the coronavirus disease 2019 (COVID-19) which has ravaged all aspects of life, especially health systems. Radiology services, in particular, are under threat of being overwhelmed by the sheer number of patients affected, unless drastic efforts are taken to contain and mitigate the spread of the virus. Proactive measures, therefore, must be taken to ensure the continuation of diagnostic and interventional support to clinicians, while minimizing the risk of nosocomial transmission among staff and other patients.

Effects of growth technique on the microstructure of ternary semiconductor compound.

X-ray diffraction (XRD) and Energy-dispersive X-ray fluorescence spectrometer (EDXRF) are employed to investigate the microstructure of bulk specimens grown through the Bridgman technique and traveling heater process, respectively. We investigate the lattice parameters, grain sizes, and microstrains of the two grown samples. For a crystal grown by the vertical Bridgeman method, the vacancy serves as an acceptor, resulting in p-type conduction, whereas the vacancy expected to serve as a donor, occurring in n-type conduction for the crystal grown via the traveling heater technique.

Growth and anisotropy of transport properties of single crystals.

Single crystals of are prepared by a technique based on the vertical Bridgman procedure. The crystal chemical and phase compositions were identified by using dispersive X-ray fluorescence spectrometry and X-ray diffraction data analysis, respectively. The Hall effect and the electrical conductivity were determined in terms of temperature, parallel and orthogonal to the layer surface, and the parameters proved to be strongly anisotropic.

The use of pulse oximetry in evaluation of pulp vitality in immature permanent teeth.

Background And Aim: The current methods of pulp vitality assessment, either electric or thermal, are of limited use in children. Recently, traumatized and immature teeth may not respond to such methods and because such methods require subjective responses, it may not provide accurate results particularly in children. Pulse oximetry, an atraumatic approach, is used to measure oxygen saturation in vascular system.
