The Inverted-face Effect

2023
Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In perception, it is often the case that the ability to recognize and interpret complex stimuli feels effortless but actually demands complicated and intensive processing. This is because processing is specialized and automated for certain types of very important stimuli. Among the best examples of this phenomenon is face processing. People do not try to detect and recognize faces. It just seems to happen. However, detecting faces...

Inverting and Non-inverting OpAmps

In an inverting amplifier, the input voltage is connected through a resistor to the inverting terminal. Meanwhile, the non-inverting terminal is grounded and a feedback resistor is established between the inverting and output terminal, as depicted in Figure 1. Figure 1: The inverting amplifier The objective is to discern the relationship between the input voltage (vi) and the output voltage (vo). By applying Kirchhoff's Current Law (KCL) and presuming the operational amplifier to be ideal, the...

Single Phase Inverter

Source: Ali Bazzi, Department of Electrical Engineering, University of Connecticut, Storrs, CT. DC power is unidirectional and flows in one direction, whereas, AC current alternates directions at a frequency of 50-60 Hz. Most common electronic devices are designed to run off of AC power; therefore an input DC source must be inverted to AC. Inverters convert DC voltage to AC through switching action that repeatedly flips the polarity of the input DC source at the output or load side for part of...

Classical forelimb asymmetry analysis of the cylinder test is routinely used to assess behavioural deficits in rats following brain injury or stroke; however, it fails to detect consistent deficits in mice. This study demonstrates that quantifying paw-dragging behaviour is a more sensitive analysis of brain injury in mice.

In Vitro Evaluation of The Effects Of Er,Cr:YSGG and Diode Lasers Used on Titanium Cylinder

2025
In this study, Er,Cr:YSGG and diode lasers applied separately to the flat surface of a total of 96 specially designed titanium cylinders. A thermocouple placed on the other surface and the temperature was measured. Surface roughness analyzed by profilometer, SEM and AFM.
FAQs
As gas enters beneath the water, it occupies space that was previously filled by liquid, so the displaced volume corresponds to the gas volume inside the cylinder. Keeping the vessel filled with water before collection also reduces the amount of surrounding air that could mix with the sample and distort the measurement.
The gas volume should be interpreted alongside the water levels inside and outside the cylinder. A difference in these levels indicates that conditions within the vessel are not identical to those around it, which can affect the reading. Recording or accounting for this difference improves comparisons between gas samples and experimental trials.
Some gases can dissolve in water instead of remaining entirely in the collected space. If dissolution occurs, the measured volume may be lower than the amount of gas produced by the reaction. Considering solubility helps explain unexpectedly small readings and indicates whether water displacement is appropriate for comparing gas production.
Fill the cylinder with water and remove trapped air before turning it upside down. Secure it so that the vessel remains stable while gas enters beneath the opening. These steps prevent air pockets, movement, and accidental loss of gas from altering the volume recorded during collection.
Collect the gas formed by the reaction and read its volume from the cylinder graduations after the gas has been trapped. Comparing the measured volume with the expected or comparative volume provides an estimate of reaction yield. Reliable interpretation requires attention to trapped air, water-level differences, and gas solubility.
This arrangement supports experiments that examine gas production during chemical reactions, compare gas volumes under controlled conditions, or assess differences between trials. In chemistry teaching and laboratory work, the resulting volume measurements can connect an observable gas collection outcome with reaction behavior and provide evidence for evaluating experimental results.
