Citizen scientists and professional astronomers in Colombia, Venezuela and Chile performed a set of simple observations of the phenomenon aimed to measure the speed of light and lunar distance. This initiative is part of the so called "Aristarchus Campaign", a citizen astronomy project aimed to ...
Development of a do-it-yourself (D.I.Y.) gel electrophoresis apparatus for Grade-12 STEM general biology students A hurdle to effective science education in schools is often the lack of teaching materials. Teaching science education in the 21st century requires direct visualization and manipulation...
As walking and turning while dual‐tasking (DT) have been suggested to induce freezing, the addition of a DT is often used to elicit FoG in the laboratory environment [12, 19]. Significant advancements in technology using wearable inertial sensors provides a new opportunity to objectively ...
When the pendulum locked, you can place the laser tool at various angles to project non-level straight lines. The laser beam will blink every 3-5 seconds to remind you that it's not self-leveling now. Multiple Line Switching Functions ...
we can observe them but also allow us to extend our observation capability to even heavier binary black-hole systems. This will allow us to shed light on many important questions, such as: What is the precise astrophysical production route of binary black-hole systems of tens of solar masses...
The governments' isolation measures to contain the transmission of COVID-19 imposed a dilemma for the people at the bottom of the pyramid. Since these
As you load more model objects into RAM, your app will probably feel more responsive, but you can’t starve out other apps or the OS will terminate your app! The starter project The starter project, EmployeeDirectory, is a tab bar-based app full of employee information. It’s like the ...
results obtained from the HWD under varied conditions are encouraging and can be used to develop an algorithm, in the next stage of the project, for predicting heart failure. The proposed HWD is lightweight and is 120.1 × 125 mm in dimensions that can conveniently be worn on the ...
The hydraulic drive concept is based on a frequency-controlled asynchronous servo motor with a drive power of 65 kW. On a common drive shaft, a ... E Siemer 被引量: 0发表: 2012年 Measuring arrangement for use in e.g. yaw rate sensor for optically measuring speed of drive shaft of asy...
This paper presents e-resilience as a framework for assessing the extent to which retail centres have spatially differentiated vulnerability to the impacts of online consumption. This extends the conceptual model of resilience as applied to retail, and is operationalised through a novel methodology tha...
