Virtual reality (VR) technology may serve as an effective non-pharmacological analgesic to aid pain management.During VR distraction, the individual is immersed in a game presented through a head-mounted display (HMD).The technological level of the HMD read more can vary, as can the use of different input devices and the inclusion of sound.While mo
Many micro-scraps are generated when a micro-triangular pyramid array (MTPA) is machined by the fly-cutting method.Micro-scraps are generally not removed quickly enough; therefore, these residual micro-scraps participate in the click here cutting process again, scratching the workpiece surface and accelerating diamond tool wear.To remove micro-scra
Spiral wave initiation in the heart muscle is a mechanism for the onset of dangerous cardiac arrhythmias.A standard protocol for spiral wave initiation is the application of a stimulus in the refractory tail of a propagating excitation wave, a region that we call the "classical vulnerable zone." Previous studies of vulnerability to spiral wave init
The bionomy and ecology of Aphis craccivora on Robinia pseudoacacia was studied.The number of gen-erations per year was determined, as well the lifespan of a generation and fecundity of the females.For the first time the strategy of development of a dangerous pest has been determined which enables it to spread worldwide.A.craccivora is a cosmopolit
Tropical peat water is abundantly available in peatlands nature reserve, especially on Borneo Island.However, this water source contains humic substances that could be harmful to human health if consumed without undergoing water treatment process.Although tropical peat water could be treated with conventional treatment, the system possesses drawbac
